The present disclosure relates to a robot cleaning system, a base station, and a control method, and in particular, to a robot cleaning system capable of automatically replacing a mopping module, and a corresponding base station and control method.
With the development of sciences and technologies, robots are playing an increasingly important role in people's life, and in particular, domestic robots help emancipate people from burdensome housework, where cleaning robots are widely favored by users because of relatively wide applicability.
Existing cleaning robots can move autonomously and work without manual direct control and operating, and further have functions such as path planning, automatic obstacle avoidance, man-machine interaction, and returning for charging. Although the existing cleaning robots can meet a daily requirement of people for sweeping trash on the ground, the existing cleaning robots usually has no mopping function. In addition to the requirement of sweeping trash on the ground, many users further intend that the cleaning robots can mop, thereby keeping the ground in a relatively neat state. In terms of the mopping function of the cleaning robots, some corporations home and abroad make attempts one after another. For example, the Irobot corporation in USA submits the patent application No. CN108378786A which discloses a cleaning pad dedicated to a mobile robot, and the cleaning pad can absorb and retain a cleaning solution, and is suitably combined with more than one tool; The Ecovacs robot corporation submits the patent application No. CN107788913A, which discloses a ground cleaning robot equipped with a mopping cloth, and the ground cleaning robot detects a ground type during working, thereby avoiding a carpet; and so on. It is very easy for a mopping cloth to become dirty during working. Therefore, if the mopping cloth is not replaced in time, the cleaning effect is greatly degraded, and even the originally clean ground becomes dirtier. For the existing cleaning robots, mopping modules of the cleaning robot cannot be automatically replaced in time, but are usually replaced manually, and the users need to continuously pay attention to the cleaning work process, causing a low degree of robot intelligence. Moreover, if the users do not replace the mopping modules in time, the cleaned ground is further contaminated. This problem is particularly evident to a user with a relatively large indoor area.
Therefore, it is necessary to design a new technical solution to resolve the foregoing technical problem.

The cleaning robot 100 is usually used for clearing different regions in a house, thereby comprehensively cleaning rooms. However, different regions in a house are usually contaminated to different extents, and in particular, it is difficult to clean some regions that may have relatively stubborn stains.

Because of arranging the vibration motor, the mopping module 310 vibrates, and if the mopping module 310 continuously vibrates during working, vibration transferred to another element of the cleaning robot 100 affects the working stability of the cleaning robot 100 and the working life of the element of the cleaning robot 100.

Specifically, the transfer module includes a driving member and a loading member, where the loading member is connected to the mopping module and causes the mopping module to move under the action of the driving member. The loading member includes a mopping module collection unit 231 and a mopping module providing unit 236, where the mopping module collection unit 231 is configured to move the mopping module 310 at the first operating position 251 separated from the cleaning robot 100 to the first storage unit 211; and the mopping module providing unit 236 is configured to obtain the mopping module 310 from the second storage unit 212 and move the mopping module to the second operating position 252, for the cleaning robot 100 to mount. Moreover, the loading member includes a supporting assembly, configured to support the mopping module in storage module to prevent the mopping module from falling. Specifically, the supporting assembly includes a first supporting assembly configured to support the mopping module in the first storage unit and a second supporting assembly configured to support the mopping module in the second storage unit. Specifically, the mopping module collection unit includes a first supporting assembly, and the mopping module providing unit includes a second supporting assembly. That is to say, the supporting assembly includes the first supporting assembly of the mopping module collection unit, and the second supporting assembly of the mopping module providing unit. Specifically, the mopping module collection unit 231 is configured to collect the mopping module 310 separated from the main body of the cleaning robot 100, and the mopping module providing unit 236 is configured to provide, to the cleaning robot 100, the mopping module 310 with which the cleaning robot 100 performs replacement. The first storage unit 211 cooperates with the mopping module collection unit, to collect the mopping module 310 separated from the main body of the cleaning robot 100 to the first storage unit 211; and the second storage unit 212 cooperates with the mopping module providing unit, to transfer, through the mopping module providing unit, the mopping module 310 stored in the second storage unit 212 to the cleaning robot 100 for mounting. Specifically, the cleaning robot 100 enters the base station and then reaches the operating position, and a part on the cleaning robot 100 on which the mopping module is mounted corresponds to the operating position on the base station 200. Specifically, when the cleaning robot 100 reaches the first operating position 251, the cleaning robot 100 separates the mopping module 310 mounted on the main body and places the mopping module on the first operating position 251; and when the cleaning robot reaches the second operating position 252, the cleaning robot 100 mounts the mopping module 310 placed on the second operating position 252 onto the main body of the cleaning robot 100. Specifically, the operating position includes an operating region, the region may be configured to place the mopping module 310, and the region may be provided for the cleaning robot 100 to separate the mopping module and/or for the cleaning robot 100 to mount the mopping module. Specifically, the first operating position 251 includes a first operating region, and after the robot 100 enters the base station and reaches the first operating region, the mopping module 310 mounted on the main body of the robot is separated and is placed on the first operating region, where more than one mopping module may be stacked on the first operating region; and the second operating position 252 includes a second operating region, and after the robot enters the base station and reaches the second operating region, the mopping module 310 placed on the second operating region is mounted on the main body of the cleaning robot. Specifically, one or more mopping modules 310 may be placed on the second operating region. That is to say, the operating position of the base station 200 includes an operating region, the mopping module 310 may be placed on the region, and the cleaning robot 100 is capable of replacing the mopping module of the cleaning robot 100 on the region.

As shown in
In this embodiment, the cleaning robot 100 enters the base station to replace the mopping module 310. Specifically, the base plate of the base station 200 protrudes from the cleaning surface, and only after travelling onto the base plate, the cleaning robot can enter the base station 200, and the base plate of the base station is provided with the first groove, the second groove, the first stop structure, and the second stop structure. Therefore, the base plate needs to have a specific thickness. Specifically, the cleaning robot 100 has a specific obstacle crossing capability, the obstacle crossing capability of the cleaning robot affects setting of the thickness of the base plate, and the obstacle crossing capability of the cleaning robot is affected by the height of the moving wheel of the cleaning robot. Usually, when the height of the moving wheel is relatively large, the obstacle crossing capability is relatively good. In this embodiment, the thickness of the base plate is less than 20 mm, so that the obstacle crossing capability of the cleaning robot is capable of ensuring that the cleaning robot 100 enters the base station, ensuring working stability of the robot cleaning system.
In an embodiment, to cause the mopping module 310 to be placed relatively accurately after moving from the second storage unit 212 to the second operating position 252, if the mopping module 310 is placed at the second operating position relative accurately, accuracy of mounting the mopping module 310 by the cleaning robot 100 can be improved. Specifically, the second operating position 252 is provided with a positioning magnet, a magnetic element is mounted on the mopping module, and when the mopping module falls from the second storage unit 212, the position of the mopping module 310 after falling is corrected because of adsorption of the positioning magnet. Specifically, the second operating position 252 is provided with four positioning magnets, the mopping module 310 is provided with four magnetic elements, and positions of the four positioning magnets correspond to those of the four magnetic elements. Specifically, the mopping module 310 is further provided with a magnetic element provided for the cleaning robot 100 to mount the mopping module. Specifically, for the magnetic element used for alignment and the magnetic element used for mounting, one magnetic element may be used to implement two functions, or two magnetic elements may be used to respectively implement alignment and mounting. Specifically, when two magnetic elements are used, the magnetic element used for alignment is magnetically weaker than the magnetic element used for mounting. Specifically, when the mopping module 310 includes two or more magnetic elements, there is an anti-interference structure between the magnetic elements.
In this embodiment, the loading member includes a mopping module collection unit 231, the mopping module collection unit 231 further includes a first supporting assembly (referring to
In this embodiment, the lifting mechanism 232 further includes a pickup assembly. In this embodiment, the pickup assembly includes an adsorption assembly 233, and the adsorption assembly 233 is disposed at a tail end of the lifting mechanism, and picks up the mopping module 310 by the adsorption assembly 233. In this embodiment, the adsorption assembly 233 includes a magnetic element, configured to perform a magnetic action with the magnetic element 314 of the rear board 311 of the mopping module to adsorb the mopping module 310. Specifically, in this embodiment, the magnetic element includes a magnet. Specifically, the adsorption assembly 233 and the lifting mechanism 232 are combined, and when the mopping module collection unit needs to collect the mopping module 310, the lifting mechanism elongates to be in the second extension state, and the adsorption assembly 233 disposed at the tail end of the lifting assembly approaches the mopping module 310 with extension of the lifting mechanism and adsorbs the mopping module 310 through a magnetic action, or the adsorption assembly 233 comes into contact with the mopping module 310 and adsorbs the mopping module 310 through a magnetic action. In this embodiment, the mopping module 310 is provided with four magnetic elements 314, the mopping module collection unit is provided with four the lifting mechanisms 232, each lifting mechanism 232 is provided with a magnetic element, and the four lifting mechanisms 232 on the mopping module collection unit synchronously elongate or retract. The magnetic element on the lifting mechanism 232 corresponds to the magnetic element 314 on the mopping module 310, to pick up the mopping module 310. When the mopping module collection unit needs to collect the mopping module, the lifting mechanism 232 extends to adsorb the mopping module 310 through the adsorption assembly 233, the adsorbed mopping module 310 is a dirty mopping module 310 that is separated from the main body of the cleaning robot 100 and has worked for a period of time, and the cleaning robot 100 travels to the first operating position 251 of the base station 200 to separate the dirty mopping module 310 from the main body of the cleaning robot 100. However, when separating the mopping module 310, the cleaning robot 100 cannot ensure that the mopping module 310 is accurately aligned with the mopping module collection unit at all moments. Consequently, correspondingly, the position of the magnetic element on the mopping module collection unit cannot be completely aligned with that of the magnetic element 314 on the mopping module 310 always, as described above. In other embodiments, the connection manner and the collection manner of the mopping module 310 may be frequently used. In this embodiment, by arranging the magnetic elements, because of attraction between the magnetic elements, even if the position of the mopping module 310 is not completely aligned, the magnetic elements have a calibration function. A beneficial effect of this design lies in that, through adsorption of the magnetic element, the process of collecting the mopping module 310 by the mopping module collection unit is calibrated, ensuring that the mopping module collection unit has relatively good working stability.

The transmission mechanism may asynchronously drive the first blocking sheet telescoping mechanism 270 and the second blocking sheet telescoping mechanism 280 to move, and may alternatively synchronously drive the first blocking sheet telescoping mechanism 270 and the second blocking sheet telescoping mechanism 280 to move. A specific form is not limited. The transmission mechanism in this embodiment of the present disclosure is simultaneously meshed with the first blocking sheet telescoping mechanism 270 and the second blocking sheet telescoping mechanism 280 through the gear and rack structure. When the transmission mechanism moves, the first blocking sheet telescoping mechanism 270 and the second blocking sheet telescoping mechanism 280 synchronously move, and switching between the extension position and the retraction position is implemented through forward rotation and reverse rotation of the motor. Such setting enables each stage of release process of the mopping module to be precise and stable, and a case that the first blocking sheet telescoping mechanism 270 moves, while the second blocking sheet telescoping mechanism 280 does not operate, causing a plurality of mopping modules to be simultaneously released onto the base plate, or a similar case does not occur.
As shown in
When the mopping module 310 is used by the cleaning robot 100 for mopping to a specific extent or for a specific time and needs to be replaced, the robot travels to the base station 200. In this case, the first mopping module lifting frame 1 is located below, the robot travels to the operating position of the base station 200, the mopping module 310 of the robot is aligned with the first mopping module lifting frame 1, then the mopping module 310 on the robot separated from the cleaning robot is detached, and the detached mopping module 310 separated from the cleaning robot descends onto the first mopping module lifting frame 1. Then, the robot leaves the first mopping module lifting frame 1 or the base station. Specifically, the robot enters the first operating position of the base station, separates the mopping module 310, and places the mopping module 310 on the first mopping module lifting frame 1. Then, the first mopping module lifting frame 1 is driven through the driving member 5 to ascend, the first mopping module lifting frame 1 holds up the mopping module 310 separated from the cleaning robot to ascend, and then reach the first supporting assembly 2, and the first supporting assembly 2 supports the mopping module 310 separated from the cleaning robot to cause the mopping module to not descend as the first mopping module lifting frame 1 descends. Then, the first mopping module lifting frame 1 is capable of descending under driving of the driving member 5, to prepare for next arrival of the robot. A plurality of mopping modules 310 to be replaced are stacked in advance in the second storage unit, and are supported through the second supporting assembly 4, and when the second mopping module lifting frame 3 descends, at least one mopping module 310 is caused to descend from the second supporting assembly 4 of the storage module onto the second mopping module lifting frame 3. When the second mopping module lifting frame 3 continues to descend, the second mopping module lifting frame 3 and the at least one mopping module 310 descending onto the second mopping module lifting frame descend to the bottom. In this case, the robot may travel to the top of the second mopping module lifting frame to automatically mount the mopping module 310 on the second mopping module lifting frame onto the bottom of the robot. Specifically, when the mopping module 310 is mounted, the cleaning robot 100 enters the second operating position of the base station, and mounts the mopping module placed on the second mopping module lifting frame 3 onto the cleaning robot 100. Through the foregoing process, the mopping module used by the robot for mopping is automatically replaced. After a new replacement mopping module 310 is used and dirty, the foregoing steps may be performed, and a plurality of mopping modules 310 may be supported on the first supporting assembly 2.
To better understand the base station 200 for a cleaning robot in this application, the base station is further explained and described below. As shown in
The first mopping module lifting frame 1 is capable of ascending or descending in the vertical direction, the first mopping module lifting frame 1 is capable of bearing the mopping module 310 separated from the cleaning robot and driving the mopping module 310 separated from the cleaning robot to ascend.
In a feasible implementation, the transfer module of the base station includes at least one guiding rod body, and the first mopping module lifting frame 1 and the second mopping module lifting frame 3 are disposed on the guiding rod body and are slidable along the guiding rod body to ascend or descend. Specifically, the guiding rod body includes a first guiding rod body and a second guiding rod body at least. Specifically, the mopping module collection unit may include at least one first guiding rod body 6, the first guiding rod body 6 extends along the vertical direction, and the lifting frame for the mopping module 310 separated from the cleaning robot is disposed on the first guiding rod body 6 and can slide along the first guiding rod body 6 to ascend or descend. Specifically, to fix the first guiding rod body 6, the base station for a cleaning robot may include a base plate 250, and the first guiding rod body 6 is connected to the base plate 250. The first mopping module lifting frame 1 is provided with a through-hole, and the first mopping module lifting frame 1 is sleeved on the first guiding rod body 6 through the through-hole and can slide along the first guiding rod body 6 to ascend or descend.
In a preferred implementation, there are a plurality of first guiding rod bodies 6, and different positions on the first mopping module lifting frame 1 are provided with a plurality of through-holes. For example, when the first mopping module lifting frame 1 is roughly in the shape of a rectangle on the horizontal plane, and there may be 4 through-holes respectively provided at corners of the rectangle. In this way, when the first mopping module lifting frame 1 slides along the first guiding rod body 6, stability of the entire first mopping module lifting frame 1 can be ensured, and smoothness of ascending and descending is improved.
When the first mopping module lifting frame 1 descends onto the bottom along the first guiding rod body 6, that is, falls onto the base plate 250, the robot needing to replace the mopping module travels onto the first mopping module lifting frame 1, the robot is automatically detached from the dirty mopping module at the bottom of the robot, and the detached mopping module descends onto the base plate. Specifically, the cleaning robot moves to the first operating position 251, the cleaning robot separates the mopping module and places the mopping module on the first operating position of the base plate. That is to say, the mopping module 310 separated from the cleaning robot descends onto the first mopping module lifting frame 1.
As shown in
The limit member 21 has at least two states, and when the limit member 21 is in a first state, the first mopping module lifting frame 1 when ascend is capable of causing the mopping module 310 on the first mopping module lifting frame 1 to pass through the limit member 21; and when the limit member 21 is in a second state, the limit member 21 is capable of propping the mopping module 310.
Usually, the limit member 21 is in the second state. When the first mopping module lifting frame 1 ascends to the limit member 21, the first mopping module lifting frame 1 butts the limit member 21 to cause the limit member 21 to rotate, and the limit member 21 overcomes a force of the reset member 22 to rotate. Then, the limit member 21 is in the first state, and the first mopping module lifting frame 1 is capable of ascending to the top of the limit member 21. Then, the limit member 21 restores to the second state under the action of the force of the reset member 22. When the first mopping module lifting frame 1 descends, the mopping module 310, on the first mopping module lifting frame 1, separated from the cleaning robot is propped by the limit member 21, so that the mopping module 310 does not descend, and is recycled and stacked on the limit member 21. In this way, the dirty mopping module 310 separated from the cleaning robot is stored.
In a feasible implementation, there may be a plurality of limit members 21 and matching reset members 22, and the plurality of limit members 21 are capable of propping different positions at edges of the mopping module 310 separated from the cleaning robot, thereby ensuring stability of propping the mopping module 310 separated from the cleaning robot, so that the mopping module 310 separated from the cleaning robot does not fall.
In a feasible implementation, the base station 200 for a cleaning robot may include: a first mopping module recycling bracket 330 extending along the vertical direction. The limit member 21 and the reset member 22 may be mounted on the first mopping module recycling bracket 330, the first mopping module recycling bracket 330 is located on a side of the mopping module 310 separated from the cleaning robot and stacked on the limit member 21, and when there are a plurality of dirty mopping modules 310 separated from the cleaning robot and stacked on the limit member 21, the mopping modules 310 separated from the cleaning robot and stacked on the limit member 21 may be prevented from falling.
As shown in
In a feasible implementation, as shown in
In a preferred implementation, as shown in
When the second mopping module lifting frame 3 carrying at least one mopping module 310 obtained from the second storage unit 212 descends to the bottom along the second guiding rod body 7, that is, falls onto the base plate 250, the robot on which a clean mopping module is mounted needs to travel onto the second mopping module lifting frame, and the robot automatically mounts the mopping module 310 on the second mopping module lifting frame onto the bottom of the robot, and then leaves the second mopping module lifting frame, to continue to perform programmed mopping work.
The clamping member 41 has at least two positions, and when the clamping member 41 is at the first position, the second mopping module lifting frame 3 when descending is capable of causing at least one mopping module placed on the clamping member 41 to be detached from the clamping member 41; and when the clamping member 41 is at the second position, the clamping member 41 is capable of propping the mopping module 310.
To cause the mopping module 310 placed on the clamping member 41 to be detached from the clamping member 41 when the second mopping module lifting frame 3 descends, as shown in
When the second mopping module lifting frame 3 descends, the guiding surface 431 butts one end of the clamping member 41, the one end of the clamping member 41 deflects under the action of the guiding surface 431, and then the clamping member 41 is rotated, so that the other end of the clamping member 41 is detached from the mopping module 310. In this case, at least one lowest mopping module 310 of the stacked mopping modules 310 falls onto the second mopping module lifting frame 3. In the foregoing manner, through displacement of the second mopping module lifting frame 3 in the vertical direction and cooperation with the guiding surface 431, the clamping member 41 is rotated on the horizontal plane.
After the second mopping module lifting frame 3 continues to descend, and one end of the clamping member 41 is detached from the guiding surface 431, the clamping member 41 is rotated under driving of the pressure biasing member 42, so that the other end of the clamping member 41 approaches the mopping module 310. In this case, the other end of the clamping member 41 is at least inserted between the first mopping module 310 and the second mopping module 310 counted from bottom to top on the second mopping module lifting frame 3. In this way, the clamping member 41 is capable of propping the second mopping module 310 and a mopping module 310 above the second mopping module. The first mopping module 310 is placed on the second mopping module lifting frame 3, and is capable of continuing to descend to the bottom with the second mopping module lifting frame 3. In this case, the robot from which the dirty mopping module 310 is dismount may travel to the top of the second mopping module lifting frame to automatically mount the mopping module 310 on the second mopping module lifting frame onto the bottom of the robot. Through the foregoing process, the mopping module used by the robot for mopping is automatically replaced. After a new replacement mopping module is used and dirty, the foregoing steps may be performed, and a plurality of mopping modules may be supported on the second supporting assembly 4. The robot may adsorb the mopping module in a magnetic adsorption manner, and provided that a magnetic force is removed when the mopping module needs to be dismounted, the mopping module automatically descends.
In this application, the first mopping module lifting frame 1 and the second mopping module lifting frame 3 collect and store the mopping modules 310 separated from the cleaning robot in an ascending and descending manner and sequentially release the stored mopping modules 310. In the manner, the structure is simple, stability of the system is relatively good, and a stuck phenomenon and the like are not easy occur, so that the base station for a cleaning robot can normally run for a long time. In a feasible implementation, as shown in
In the foregoing process, the mopping module 310 separated from the cleaning robot may be understood as a dirty mopping module replaced from the robot. The mopping module 310 may be understood as a clean mopping module that is stored on the clamping member 41 in the base station for a cleaning robot in advance in a stacked form and is at least one in quantity. Specifically, the clamping member is located in the second storage unit 212.
In a feasible implementation, as shown in

To make it convenient to mount the motor 52, to cause the motor 52 to be located on a side of the entire base station, transmission between the motor 52 and the rotatable member 51 may be implemented through a plurality of synchronization belts 53 and a plurality of belt pulleys 54. For example, as shown in
Specifically, the rotational belt extensible along the vertical direction is disposed between the first mopping module lifting frame and the second mopping module lifting frame, and the motor is disposed at one end, of the rotational belt extensible along the vertical direction, opposite to a remote end of a base plate of the base station. Moreover, the driving member further includes: a rotational belt extensible along a horizontal direction connected to the rotational belt extensible along the vertical direction, where the motor is disposed at one end, of the rotational belt extensible along the horizontal direction, far away from a remote end of the storage module.
In a feasible implementation, the driving member 5 may include: a rotational belt 55 extensible along the vertical direction; and a motor 52 configured to drive the rotational belt 55. The first mopping module lifting frame and the second mopping module lifting frame 3 may be fixed to the rotational belt 55 through a fixing buckle 56, so that the rotational belt 55 can drive the mopping module 310 separated from the cleaning robot to ascend or descend and the second mopping module lifting frame 3 to ascend or descend. Preferably, the mopping module 310 separated from the cleaning robot and the second mopping module lifting frame 3 may be an integrated structure. In a feasible manner, when the first mopping module lifting frame and the second mopping module lifting frame move in the vertical direction, and there is no relative movement between the first mopping module lifting frame and the second mopping module lifting frame, so that the first mopping module lifting frame and the second mopping module lifting frame synchronously move. Before the cleaning robot enters the base station to replace the mopping module, the first mopping module lifting frame descends. Meanwhile, the second mopping module drives a mopping module to descend, and the cleaning robot enters the base station, separates the dirty mopping module and places the dirty mopping module onto the first mopping module lifting frame. The cleaning robot continues to advance, and mounts the mopping module placed on the second mopping module lifting frame onto the cleaning robot. Subsequently, the cleaning robot leaves the base station, the first mopping module lifting frame and the second mopping module lifting frame synchronously ascend, the dirty mopping module on the first mopping module lifting frame is taken in through the limit member, and meanwhile a clean mopping module is placed on the second mopping module lifting frame to wait for next arrival of the cleaning robot. Preferably, the first mopping module lifting frame and the second mopping module lifting frame may serve as a whole structure, that is, the first mopping module lifting frame and the second mopping module lifting frame move upward or downward as a whole. No relative movement between the first mopping module lifting frame and the second mopping module lifting frame can simplify the structure of the base station for a cleaning robot, and improve working stability of the base station. Meanwhile, because the first mopping module lifting frame 1 and the second mopping module lifting frame 3 may be fixed to the rotational belt 55 through the fixing buckle 56, the first mopping module lifting frame 1 and the second mopping module lifting frame 3 simultaneously ascend when the motor 52 drives the rotational belt 55 to ascend. When ascending, the first mopping module lifting frame 1 transports the dirty mopping module replaced from the robot onto the limit member 21 for propping. When the motor 52 drives the rotational belt 55 to descend, the mopping module 310 separated from the cleaning robot and the second mopping module lifting frame 3 simultaneously descend. When descending, the second mopping module lifting frame 3 carries and transports a lowest mopping module 310 stored on the clamping member 41 to the bottom, for the robot to replace the mopping module.
For example, the rotational belt 55 may be in the shape of a ring, and the base station for a cleaning robot includes: two belt pulleys 54 arranged up and down, where the rotational belt 55 is sleeved on the belt pulleys 54, the motor 52 drives, through a synchronization transmission belt, one of the belt pulleys 54 to rotate, thereby implementing counterclockwise rotation and clockwise rotation of the rotational belt 55, and the rotational belt 55 is capable of driving the first mopping module lifting frame 1 and the second mopping module lifting frame 3 to ascend or descend. Certainly, the transmission belt may be alternatively in the shape of a strip, the base station for a cleaning robot includes only one rotatable shaft, and the motor 52 drives the rotatable shaft to rotate, and the transmission belt is capable of winding around the transmission shaft, to control ascending and descending of the first mopping module lifting frame 1 and the second mopping module lifting frame 3 through winding and releasing during rotation.
In the foregoing several implementations, both the first mopping module lifting frame 1 and the second mopping module lifting frame 3 ascend and descend through the same driving member 5, and the driving member 5 drives the first mopping module lifting frame 1 and the second mopping module lifting frame 3 to synchronously ascend or synchronously descend or drives one to ascend and the other to descend. In this way, synchronization between the first mopping module lifting frame 1 and the second mopping module lifting frame 3 may be relatively good, and the structure of the entire driving member 5 is simple and relatively compact.
This application further provides a cleaning robot system, including: any one of the foregoing base stations for a cleaning robot that are described above; and a cleaning robot, where a cleaning element is capable of being mounted on the cleaning robot, the cleaning robot is capable of separating and/or mounting the cleaning element from and/or on the base station for a cleaning robot, and the cleaning element is a mopping module 310.
In a feasible implementation, the base station for a cleaning robot includes a charging module, and the charging module provides energy to the cleaning robot when the cleaning robot docks to the base station. The cleaning robot returns, when being at a low power level, to the base station for a cleaning robot and leaves, after being charged fully, the base station for a cleaning robot, to continue to perform cleaning work.
An embodiment of this application provides a base station 200, referring to
In this embodiment, the base station 200 includes: a housing 3; a second supporting assembly disposed on the housing 3, where the second supporting assembly includes a first supporting mechanism 201; and a second supporting mechanism 202 disposed on the housing 3. On the housing 3, there are a storage module 210 in which mopping modules 310 are stacked, and an operating position located below the storage module 210. The first supporting mechanism 201 has a supporting state of supporting the mopping module 310 and a retraction state of not supporting the mopping module 310. The second supporting mechanism 202 has a holding-up state of supporting the mopping module 310 in the storage module 210 and an open state of releasing at least one mopping module 310 to the operating position.
As shown in
The base station 200 provided in this embodiment is provided with the first supporting mechanism 201 and the second supporting mechanism 202 matching each other, so that when the cleaning robot needs to replace a mopping module 310, the second supporting mechanism 202 is switched to the open state, at least one mopping module 310 is delivered the operating position, and the cleaning robot enters the operating position to replace the mopping module 310 at the operating position. Correspondingly, remaining mopping modules 310 in the storage module 210 are supported by the first supporting mechanism 201 to avoid falling, until the second supporting mechanism 202 is reset to the holding-up state to support the mopping module 310 again until the cleaning robot performs replacement again with a new mopping module 310. Therefore, when being applied to a scenario of replacing a mopping module 310, the base station 200 provided in this embodiment is capable of automatically delivering a mopping module 310, thereby automatically replacing the mopping module 310, reducing intervention by a user in mopping module 310 replacement, and improving user experience.
In this embodiment, when being in the holding-up state, the second supporting mechanism 202 supports the mopping module 310 in the storage module 210, and the first supporting mechanism 201 is in the retraction state. The second supporting mechanism 202 releases, when being in the open state, at least one mopping module 310 to the operating position, and the first supporting mechanism 201 supports, when being in the supporting state, remaining mopping modules 310 in the storage module 210. In this way, the first supporting mechanism 201 matches the second supporting mechanism 202, and mopping modules 310 may be delivered one by one, to make it convenient for the cleaning robot to replace a single mopping module 310 at a single time.
Certainly, in another embodiment, the base station 200 may further deliver two or even more mopping modules 310 at each time, to allow two or more cleaning robots to perform replacement with new mopping modules 310. This is not particularly limited in this application.
In this embodiment, a plurality of mopping modules 310 are stacked in the storage module 210. Specifically, the plurality of mopping modules 310 are stacked in the second storage unit 212 of the storage module 210 and are supported by the second supporting mechanism 202 to prevent falling, where the second supporting mechanism 202 is located in the second storage unit. The mopping module 310 has a specific structural rigidity, and is capable of maintaining a basic shape under supporting of the first supporting mechanism 201 or the second supporting mechanism 202. The mopping module 310 may be a mopping board to which a mopping paper or mopping cloth is attached. Additionally, the mopping module 310 may have a bracket to which a mopping paper or mopping cloth is attached, and the bracket may be a rigid bracket. Certainly, the material of the bracket may be a metal or plastic material, provided that the bracket can keep the entire shape unchanged.
The second storage unit 212 is wholly in a cuboid structure, and correspondingly, the mopping module 310 is wholly in a rectangular board body structure. The first supporting mechanism 201 and the second supporting mechanism 202 are located on two sides at the bottom of the second storage unit 212, to support the mopping module 310 in different states. The mopping module 310 in the storage module 210 is a clean mopping module 310, that is, a mopping module 310 with which replacement is to be performed. Specifically, the operating position is located below the storage module 210. Specifically, the second operating position 252 is located below the second storage unit 212, and the robot may enter the base station, dock at the second operating position 252, and mount the clean mopping module 310 at the second operating position 252.
The second operating position 252 is located below the second storage unit 212, and is configured to receive the mopping module 310 delivered through the second supporting mechanism 202. The operating position has a carrying groove for holding a mopping module 310. A minimum distance between the second supporting mechanism 202 and the carrying groove bottom of the groove is greater than a thickness of a single mopping module 310. There may be an opening formed on a side of a groove wall 52 of the carrying groove 51, to make it convenient for the cleaning robot to enter or leave. Certainly, the groove wall 52 of the carrying groove 51 may further limit the mopping module 310, to avoid a case that when the cleaning robot enters or leaves, the mopping module 310 is displaced, to affect smooth replacement.
The first supporting mechanism 201 and the second supporting mechanism 202 are located on two sides at the bottom of the storage module 210, and the first supporting mechanism 201 or the second supporting mechanism 202 supports the mopping module 310 in different states. The retraction state of the first supporting mechanism 201 and the open state of the second supporting mechanism 202 are similar. In either of the two states, the mopping module 310 in the storage module 210 is not supported, but supporting or limiting on the mopping module 310 is removed. Correspondingly, to avoid a case that all mopping modules 310 fall, supporting time points of the first supporting mechanism 201 and the second supporting mechanism 202 are mutually staggered, to deliver only the mopping module 310 with which replacement is to be performed, and keep remaining mopping modules 310 stored in the second storage unit 212.
The second supporting mechanism 202 and the first supporting mechanism 201 are linked. In this way, when the first supporting mechanism 201 and the second supporting mechanism 202 need to be driven or positions of the second supporting mechanism 202 and the first supporting mechanism 201 need to be detected, driving may be performed only in need of a single energy module, and similarly, a position state of only one supporting mechanism needs to be obtained to learn a position state of the other supporting mechanism, thereby reducing the quantity of sensors and reducing the costs.
In this embodiment, the first supporting mechanism 201 and the second supporting mechanism 202 are provided with linked structures (for example, limit protrusions 21 and 22, and a dial rod 12 described below). Through the linked structures, the first supporting mechanism 201 drives, when acting, the second supporting mechanism 202 to act, or the second supporting mechanism 202 drives, when acting, the first supporting mechanism 201 to act. In the embodiment shown in
In another embodiment, the first supporting mechanism 201 and the second supporting mechanism 202 may be provided with no linked structure, and may be each independently equipped with an energy module, to mutually independently rotate, and actions of the two are controlled through a controller to achieve mutually staggered supporting time points.
In this embodiment of this application, the first supporting mechanism 201 switches between the supporting state and the retraction state through an action, and the second supporting mechanism 202 switches between the holding-up state and the open state through an action. Action forms of the first supporting mechanism 201 and the second supporting mechanism 202 may be back-and-forth rotation, back-and-forth telescoping, or translational movement, and the action forms of the two may be the same or different. This is not uniquely limited in this application. Preferably, the first supporting mechanism 201 switches between the supporting state and the retraction state through rotation, and the second supporting mechanism 202 switches between the holding-up state and the open state through rotation.
The first supporting mechanism 201 and the second supporting mechanism 202 have specific action ranges, and the supporting state and the retraction state, and the holding-up state and the open state may be an initial position and a final position or an initial state and a final state of the respective action ranges. For example, if the action form is translation or rotation, the first supporting mechanism 201 and the second supporting mechanism 202 has a back-and-forth translation range and back-and-forth rotation range with a specific distance or angle, and the supporting state and the retraction state, and the holding-up state and the open state may be endpoint positions or endpoint states of the translation range and the rotation range.
Specifically, the first supporting mechanism 201 is capable of rotating around a first rotational axis. The first supporting mechanism 201 switches between the supporting state and the retraction state through rotation. The second supporting mechanism 202 is capable of rotating around a second rotational axis 11. The second supporting mechanism 202 switches between the holding-up state and the open state through rotation. The first rotational axis and the second rotational axis 11 are parallel to each other. In the embodiment shown in
In the embodiment shown in
The first supporting mechanism 201 includes a rotatable stop board (201a, 201b) configured to rotate around the second rotational axis 11. A supporting rod 13 is disposed on the rotatable stop board. The supporting rod 13 is, when being in the retraction state, located outside the storage module 210, and stretches, when being in the supporting state, into the second storage unit 212.
To make it convenient for the first supporting mechanism 201 and the second supporting mechanism 202 to be linked, a dial rod is further disposed on the rotatable stop board. The rotatable stop board is located on a side of the supporting board along an axial direction of the first rotational axis. The axial direction along the first rotational axis is a front-rear direction facing
A side surface of the supporting board at the connection end 25 is provided with a first limit protrusion 21 and a second limit protrusion 22. The first limit protrusion 21 and the second limit protrusion 22 are circumferentially spaced apart by a specific distance, a gap is formed between the first limit protrusion 21 and the second limit protrusion 22, and the dial rod is threaded between the first limit protrusion 21 and the second limit protrusion 22 through the gap. The dial rod is located between the first limit protrusion 21 and the second limit protrusion 22, and is limited by the first limit protrusion 21 and the second limit protrusion 22 during rotation.
To make it convenient for the first supporting mechanism 201 to be inserted between two neighboring mopping modules 310, then bear remaining mopping modules 310, and prevent the remaining mopping modules 310 from falling, there is a gap 301 between the two neighboring mopping modules 310, and the first supporting mechanism 201 may be insert into the gap 301 to bear the mopping module 310 above the first supporting mechanism. As shown in
The second supporting mechanism 202 and the first supporting mechanism 201 linked to the second supporting mechanism form the second supporting assembly 60. The mopping module providing unit 236 is provided with a plurality of second supporting assemblies 60. At least two second supporting assemblies 60 are respectively mounted on two sides of the storage module 210 along a first direction; and the first direction F is perpendicular to the vertical direction. In this embodiment, the first direction F is a left-right direction facing
As shown in
In the second supporting assembly 60, the first supporting mechanism 201 temporarily supports the mopping module 310 when the mopping module 310 is delivered, and the second supporting mechanism 202 continuously supports the mopping module 310 when no mopping module 310 is delivered. When the second supporting mechanism 202 switches from the holding-up state to the open state, the mopping module 310 descends in dependence on gravity before falling onto the bottom of the operating position. There are at least three second supporting assemblies. Correspondingly, the quantity of first supporting mechanisms 201 and the quantity of second supporting mechanisms 202 stably support the mopping modules 310, to prevent the mopping modules 310 from autonomously falling, and there are at least three second supporting assemblies 60.
In the embodiment shown in
To avoid a case that rotation forms interference, the second supporting assemblies 60 located on two sides of the storage module 210 are staggered. In this way, the supporting board has a larger length, thereby forming a delivery path when the mopping module 310 is delivered, to avoid a case that the mopping module 310 directly falls and deviates. A plurality of second supporting assemblies 60 or a plurality of second supporting mechanisms 202 are at different positions in the second direction. Two second supporting assemblies 60 are distributed on the left side of the storage module 210, and two second supporting assemblies 60 are distributed on the right side of the storage module 210. A distance between the two second supporting assemblies 60 on the left side is larger than a distance between the two second supporting assemblies 60 on the right side. There is a transmission gear group between two second supporting assemblies 60 located on the same side, and the transmission gear group implements transmission from a first driving shaft 401 to the pivoting shaft 402.
To avoid a case that the mopping module 310 deviates when being delivered, and ensure that the mopping module 310 is subsequently replaced smoothly, a length of the supporting board in the holding-up state stretching into the storage module 210 is greater than ½ of a width of the storage module 210 along the first direction F. In this way, the larger length of the second supporting mechanism 202 may form a descending path of the mopping module 310, to avoid a case that the mopping module 310 deviates when being delivered, ensure an accurate delivery position of the mopping module 310, and further make it convenient for the cleaning robot to perform replacement.
To be conveniently inserted between two neighboring mopping modules 310, the supporting rod 13 has a relatively small length. Specifically, A length of the supporting rod 13 in the supporting state stretching into the storage module 210 is less than a length of the supporting board in the holding-up state stretching into the second storage unit 212.
Further, a gap 301 is formed between edges (landing edges 302) of two neighboring stacked mopping modules 310. An outer end 131 is flat, to make it convenient to stretch into the gap 301 between the neighboring mopping modules 310. To further conveniently insert the first supporting mechanism 201 between the mopping modules 310, the supporting rod 13 has, when extending toward the outer end 131 of the supporting rod, the width gradually decreased. A width direction F2 of the supporting rod 13 is approximately parallel to a circumferential direction around the second rotational axis 11. The supporting surface of the supporting rod 13 is a curved surface.
When the mopping module 310 is delivered, as supporting boards on two sides of the mopping module 310 open toward the two sides, and the mopping module 310 descends along the bearing surfaces of the supporting boards. However, there may be a case that descending speeds or descending displacements on the two sides of the mopping module 310 are asynchronous, to cause the entire mopping module 310 to deviate laterally, until the delivery causes position deviation or overturning, which affects subsequent cleaning member replacement.
To avoid the problem, the second supporting mechanism 202 (for example, the supporting board) is further provided with a buffering portion 231. The buffering portion 231 includes a buffering inclined surface 231b; and a protrusion height of the buffering inclined surface 231b along a direction from the connection end 25 of the second supporting mechanism 202 to the free end 26 of the second supporting mechanism 202 is gradually increased. The buffering portion 231 is disposed on the supporting surface of the second supporting mechanism 202, and stops the mopping module 310 when the mopping module 310 descends, until opening to a larger degree to release the mopping module 310.
The second supporting mechanisms 202 located on the two sides of the storage module are each provided with a buffering portion 231. When the second supporting mechanism 202 rotates to open, the mopping module 310 descends, until coming into contact with the buffering inclined surface 231b of the buffering portion 231 to stop or slow descending. In this case, lateral deviation occurs on the two sides of the mopping module 310, a landing edge 302 on a side of the mopping module 310 comes into contact with the buffering inclined surface 231b in advance to stop or slow descending; and then, a landing edge 302 on the other side comes into contact with the landing edge 302 on the buffering inclined surface 231b in advance to form chasing, until the level of the mopping module 310 is restored, to eliminate the lateral deviation problem, thereby ensuring that the mopping module 310 is in an accurate to-be-replaced state during delivery. Moreover, the buffering inclined surface 231b may further reduce the descending speed of the mopping module 310, so that the mopping module is delivered into the carrying groove 51 at a relatively low speed, to further avoid a possibility that the mopping module 310 deviates.
Further, the buffering portion 231 further has a sliding inclined surface 231a; the sliding inclined surface 231a is closer to the connection end than the buffering inclined surface 231b; and a protrusion height of the buffering inclined surface 231a along a direction from the connection end 25 to the free end 26 is gradually decreased. The sliding inclined surface 231a and the buffering inclined surface 231b form a stepped structure. During descending, the mopping module 310 first comes, when sliding to the buffering portion 231, into contact with to the sliding inclined surface 231a, and the sliding inclined surface 231a is in contact with the inclined surface of the landing edge 302, so that the mopping module 310 stably slides; and then, the mopping module 310 forms, when sliding to the buffering inclined surface 231b, buffering and damping for the mopping module 310 through the buffering inclined surface 231b, to ensure that the mopping module 310 is in a level state. Preferably, the supporting board has a plurality of buffering portions 231; and the plurality of buffering portions 231 are arranged along a direction from the connection end 25 to the free end 26 to form a stepped buffering structure 23.
Specifically, the supporting board has the stepped buffering structure 23 configured to bear the mopping module 310. The stepped buffering structure 23 includes a plurality of buffering portions 231 arranged along the direction from the connection end 25 to the free end 26. Each buffering portion 231 includes a sliding inclined surface 231a and a buffering inclined surface 231b. The sliding inclined surface 231a is closer to the connection end 25 than the buffering inclined surface 231b. Along the direction from the connection end 25 to the free end 26, a protrusion height of the buffering inclined surface 231a is gradually decreased, and a protrusion height of the buffering inclined surface 231b is gradually increased. The buffering portion 231 wholly forms a “V” shaped groove, and a plurality of V shaped grooves are sequentially arranged along the direction from the connection end 25 to the free end 26, to form the stepped buffering structure 23.
When the mopping modules 310 are delivered, as the supporting boards open by an increased angle, the mopping modules 310 successively fall on the stepped buffering structure 23. When passing through a buffering portion 231 at a stage each time, the mopping module 310 is decelerated and buffered, to avoid a case that the delivery speed is excessively high and deviation occurs.

To ensure that the supporting rod 13 supports the remaining mopping modules 310 other than the lowest mopping module 310a, and avoid delivering an excessive quantity of mopping modules 310, in the holding-up state, a height difference between the free end 26 of the supporting board and the supporting rod 13 is greater than a thickness of a single mopping module 310 and less than a thickness of two mopping modules 310. In the retraction state, the outer end 131 of the supporting rod 13 is located above the lowest mopping module 310a. In the retraction state, the outer end 131 of the supporting rod 13 and the gap 301 are disposed opposite to each other along the first direction F.
In this embodiment, a transmission mechanism is disposed on the housing 3. A driving motor 400 drives, through the transmission mechanism, the plurality of second supporting assemblies 60 to synchronously act. The transmission mechanism may include a worm gear and a worm. The driving motor 400 drives, through the worm gear and the worm, the pivoting shaft 402 to rotate, and the pivoting shaft 402 may be fixedly connected to the plurality of second supporting mechanisms 202, thereby simultaneously driving the plurality of second supporting mechanisms 202 to simultaneously rotate.
Specifically, the driving motor 400, the first driving shaft 401, and a second driving shaft 406 are further disposed on the housing 3. The first driving shaft 401 and the second driving shaft 406 are respectively mounted on two sides of the storage module 210 along the first direction F. The first driving shaft 401 and the second driving shaft 406 are disposed parallel to the first rotational axis, and respectively drive pivoting shafts 402 located on two sides of the storage module 210 to rotate. The driving motor 400 is configured to drive the first driving shaft 401 and the second driving shaft 406 to rotate.
The driving motor 400 and the first driving shaft 401 are located on a side of the storage module 210 along the first direction F, and the second driving shaft 406 is located on another side of the storage module 210 along the first direction F. A side of the storage module 210 along a second direction is provided with a chain 405. The driving motor 400 drives the second driving shaft 406 through the chain 405. The second direction is perpendicular to the first direction F and the vertical direction.
A working principle of a mopping module providing unit 236 in an embodiment of this application is described below in detail with reference to
As shown in
The storage module 210 stores a plurality of stacked mopping modules 310 (310a, 310b, 310c), the operating position is located below the storage module 210, and the four second supporting assemblies 60 are respectively located on two sides of the bottom of the storage module 210. Two second supporting assemblies 60 are located on the left side. Correspondingly, two supporting boards are located on the left side, and share the same pivoting shaft 402 for driving, and are driven through the first driving shaft 401, and each supporting board corresponds to a linked rotatable stop board. Two second supporting assemblies 60 are located on the right side. Correspondingly, two supporting boards are located on the left side, and share the same pivoting shaft 402 for driving, and are driven through the second driving shaft 406, and each supporting board corresponds to a linked rotatable stop board.
The cross section of the mopping module 310 matches that of the storage module 210, and left and right edges of the mopping module 310 are close to left and right side walls of the storage module 210. In this way, the space of the storage module 210 may be used as much as possible, and it is convenient for the first supporting mechanism 201 to be inserted to support the remaining mopping modules 310.

As shown in
The supporting board rotates downward and opens gradually, and the lowest mopping module 310a begins to move downward. At the initial stage in which the supporting board rotates, the supporting rod 13 extends from the opening of the holding box 61, and stretches into the gap 301. As shown in

When being in the holding-up state, the second supporting mechanism 202 supports the mopping module 310 in the storage module 210, and the first supporting mechanism 201 is in the retraction state. The second supporting mechanism 202 releases, when being in the open state, at least one mopping module 310 to the operating position, and the first supporting mechanism 201 supports, when being in the supporting state, remaining mopping modules 310. Usually, the mopping module 310 includes a disposable mopping cloth and a washable mopping cloth, the robot cleaning system 300 in this embodiment is compatible with the disposable mopping cloth and the washable mopping cloth, and the storage module 210 is capable of storing the disposable mopping cloth and the washable mopping cloth. In an embodiment, to enable the storage module 210 to be compatible with both the disposable mopping cloth and the washable mopping cloth, the design of the storage module 210 needs to be improved, so that in a case of being compatible with the mopping clothes, the storage module 210 is still capable of ensuring relatively good working stability. Specifically, gaps of the storage module 210 in the length direction and the width direction are increased, so that a mopping module of a relatively large size is also capable of matching the storage module 210, and when a plurality of mopping modules 310 are placed in the storage unit 210, edges of the mopping modules 310 may be stacked, to ensure the capability of the storage module 210 to store the mopping modules 310 by increasing an internal gap of the storage unit 210. When there is a gap on two sides of the storage module 210, it means that the internal space of the storage module 210 is greater than the actual size of the mopping module 310. Usually, the center region of the storage module 210 is just aligned with the operating position, so that the mopping module can be relatively accurately placed on a corresponding operating position. Therefore, when the mopping module 310 is stored in the storage module, the mopping module 310 also needs to be placed on the center region of the storage module 210 as much as possible. Specifically, mopping modules 310 with which replacement is to be performed are stored in the second storage unit 212, and when the cleaning robot 100 needs to replace a mopping module, the second storage unit 212 provides a mopping module 310 to the second operating position 252 for the cleaning robot to mount. Specifically, if the mopping module 310 needs to be accurately placed on the second operating position, the mopping module 310 in the second storage unit 212 needs to fall from the intermediate region.

In another embodiment, the base station 200 may be alternatively a cleaning station configured to wash a mopping module, or the like. Moreover, a charging function is further integrated into the base station 200, and when the power level of the cleaning robot 100 is insufficient, the cleaning robot 100 may automatically return to the base station 200 for charging, to replenish electric energy.
The base station 200 includes a base 253, a functional module disposed above the base 253 and configured to perform a preset function, an accommodation cavity 258 enclosed by the functional module and the base 253 to accommodate the cleaning robot, and a charging module configured to charge the cleaning robot. The functional module is located above the accommodation cavity 258. The charging module includes charging terminals configured to dock to and charge the cleaning robot 100. The base station 200 includes a base plate 2531 and a supporting portion configured to connect the base plate and the functional module. The preset function performed by the functional module corresponds to the preset operation predefined by the base station 200. In this embodiment, the base station 200 is a mopping module replacement station configured to automatically replace a mopping module, and correspondingly, the functional module is a structure or substance required during mopping module replacement.
In this embodiment, the functional module is configured to at least perform a storage function, and the functional module includes a storage module 215 configured to accommodate a storage substance. The storage substance is a substance required when the base station 200 performs the preset operation. For example, in this embodiment, the base station 200 is a mopping module replacement station configured to automatically replace a mopping module. When mopping module replacement is performed, a new (clean) mopping module is required, and a dirty mopping module is generated. In this case, the storage module configured to accommodate these mopping modules is required. Therefore, the functional module is a storage module 210 configured to accommodate the mopping modules. In another embodiment, the functional module may be alternatively a storage module configured to store another substance, for example, configured to store an air purification module, water, or another washing medium. In another embodiment, the functional module may be alternatively configured to perform another function, for example, dust proofing, washing, or charging.
As shown in
In this embodiment, the cleaning robot 100 has a function of returning to the base station 200 to automatically replace a mopping module 310. In this case, the storage module 215 is configured to store mopping modules 310, the storage module 215 includes a first storage unit 2153 configured to store a dirty mopping module and a second storage unit 2154 configured to store a clean mopping module, and the communicating mouth 2150 includes a first communicating mouth 2151 and a second communicating mouth 2152 that are respectively located below the first storage unit 2153 and the second storage unit 2154 and that may be opened and closed. The first storage unit 2151 and the second storage unit 2152 are located abreast above the accommodation cavity 258 in the horizontal direction. The corresponding base plate 2531 has an accommodation groove configured to accommodate the dirty mopping module and an accommodation groove configured to accommodate the clean mopping module. In an aspect, the mopping modules may be limited, and in another aspect, the mopping modules may be prevented from excessively protruding from the base plate 2531, to hinder the cleaning robot 100 from moving.
The cleaning robot 100 usually has a control panel, the user may operate the control panel of the cleaning robot 100 to control actions of the cleaning robot 100, and the operating panel of the cleaning robot 100 is usually disposed on an upper surface of the cleaning robot 100. Because a function other than charging is integrated in the base station 200, the functional module is disposed above the base station and located above the accommodation cavity 258, to reduce the occupied area. However, when the functional module is disposed above the accommodation cavity 258, and when the cleaning robot 100 returns to the base station 200, the cleaning robot 100 is accommodated in the accommodation cavity 258, an upper surface of the cleaning robot 100 is blocked by the functional module, and the user cannot directly operate the operating panel on the cleaning robot 100. In this case, if the user intends to operate the operating panel on the cleaning robot 100 to cause the cleaning robot to execute a corresponding instruction, or intends to directly perform some other operations on the cleaning robot 100, the user can only manually forcibly pull out the cleaning robot 100. Such an operation dirties the hands of the user and reduces satisfaction of the user experience, and the forcible action may further cause the structure of the cleaning robot 100 to be damaged or cause the program to be disordered.
In this embodiment, the base station 200 further includes a signal transmitter 259 configured to at least send, to the cleaning robot 100, a leaving instruction signal of leaving the accommodation cavity 258, and an operating portion 340 electrically connected to the signal transmitter 259 and configured to at least control the signal transmitter to send the leaving instruction signal. When the cleaning robot 100 enters the accommodation cavity 258 of the base station 200, the operating portion 340 may be directly operated to cause the cleaning robot to leave the base station and then perform a related operation.
In an embodiment, a detachable battery pack is mounted on the body of the cleaning robot 100. When the user needs to remove the battery pack, if the cleaning robot 100 is located in the base station 200, the operating portion 340 on the base station is operated, so that the cleaning robot 100 leaves the base station and stops working, to make it convenient for the user to remove the battery pack. In an embodiment, a water tank is mounted on the cleaning robot 100, and is capable of providing moisture to the mopping module 310 to implement wet mopping on the ground. When the water storage amount in the water tank is relatively small, the user needs to add water to the water tank. In this case, if the cleaning robot 100 is located in the base station, the user may operate the operating portion 340 of the base station to cause the cleaning robot to leave the base station 200 and dock outside the base station, making it convenient for the user to remove the water tank and mount the water tank.
Certainly, another function may be further integrated in the signal transmitter 259 and the operating portion 340, so that the user can operate the operating portion 340 on the base station 200 to control the cleaning robot 100 to perform another instruction. For example, the signal transmitter 259 may not be merely limited to sending a leaving instruction signal, the signal transmitter 259 may be further configured to send an entering instruction signal of entering the accommodation cavity 258. Correspondingly, the operating portion 340 is electrically connected to the signal transmitter 259, and may control the signal transmitter 259 to send the entering instruction signal, thereby operating the operating portion 340 to control the cleaning robot 100 to execute an instruction for entering the accommodation cavity 258. Certainly, the signal transmitter 259 may be further configured to send a guiding signal of guiding the cleaning robot 100 to return or send another signal. Correspondingly, the operating portion 340 is electrically connected to the signal transmitter 259, and may control the signal transmitter 259 to send the corresponding guiding signal or another signal, to control the cleaning robot 100 to execute another instruction.
The operating portion 340 may be provided for the user to operate, to control the signal transmitter 259 to transmit a corresponding signal, thereby controlling the cleaning robot 100 to execute a corresponding instruction. For example, the user may operate the operating portion 340, to control the signal transmitter 259 to transmit a leaving signal instruction, thereby controlling the cleaning robot 100 to execute an instruction for leaving the accommodation cavity, so that when the cleaning robot 100 is accommodated in the accommodation cavity 258, the user may directly operate the operating portion 340 to control the cleaning robot 100 to leave the accommodation cavity 258, to avoid forcibly manually interfering with the cleaning robot 100, thereby effectively improving user experience. Similarly, when the signal transmitter 259 is further integrated to send the entering instruction, and when the cleaning robot 100 is located outside the base station 200, the user may alternatively operate the operating portion 340, to quickly recall (for example, one-key recall) the cleaning robot 100, to avoid looking for the cleaning robot 100 everywhere.
The operating portion 340 may be a physical operating element, a virtual operating element on a screen, or the like, and the operating element may be a button, a foot stepping pedal, or the like. When the signal transmitter 259 may send different signals, the operating portion 340 may be as what is shown in
The operating portion 340 is disposed on an outer surface of the base station 200, to make it convenient for the user to operate. As shown in
The cleaning robot 100 includes a signal receiver configured to receive a signal transmitted by the signal transmitter 259. The signal transmitter 259 may be an infrared signal transmitter, a Bluetooth signal transmitter, a Wi-Fi signal transmitter, or the like. In this embodiment, an example in which the signal transmitter 259 is an infrared signal transmitter is used. The signal transmitter 259 is disposed in the accommodation cavity 258, the accommodation cavity 258 has an opening 255 in communication with the outside provided for the cleaning robot 100 to leave and/or enter, and a supporting portion 2532 is disposed on a side of the base station 200 opposite to the opening 255, so that when the cleaning robot 100 docks, projections of the cleaning robot 100 and the functional module in the horizontal plane approximately coincide. Therefore, the structure of the base station 200 in the horizontal direction is more compact, thereby reducing the occupied area of the entire robot cleaning system 300. The signal transmitter 259 is disposed on the supporting portion 2532, and configured to transmit a signal toward the opening 255. When the cleaning robot 100 docks to the base station 200, the cleaning robot 100 is located on a side of the supporting portion 2532 facing the opening 255. Therefore, transmission of the signal transmitter 259 toward the opening 255 is to transmit a signal just directly facing the cleaning robot 100, making it convenient to receive the signal on the cleaning robot 100. However, when the cleaning robot 100 does not dock to the base station 200, the signal transmitter 259 transmits a signal to the outside of the base station 200 through the opening 255, to prevent the signal from being blocked by another component on the base station 200, making it convenient for the cleaning robot 100 to receive the signal. The signal receiver is located in front of the movement direction of the cleaning robot 100, so that it is easier to receive the signal transmitted by the signal transmitter 259.
The signal transmitter 259 may be further configured to transmit a guiding signal of guiding the cleaning robot 100 to move toward the base station 200. After detecting that its own power level is less than a threshold, the cleaning robot 100 moves toward the base station 200 according to a preset path, continuously detects, during moving, a signal sent by the charging module, and determines a position of the base station 200 according to the signal and completes charging and docking. In this embodiment, the charging terminals are located on the supporting portion 2532 or the base plate 2531. Certainly, in some embodiments, the charging terminals may be alternatively located at a position such as the bottom of the storage module 210, so that the top of the cleaning robot 100 is in contact with the charging terminals to perform charging. After entering the base station 200 to complete docking, the cleaning robot 100 starts charging, and the cleaning robot 100 leaves the base station 200 after the charging ends. In another embodiment, a manner in which the cleaning robot 100 returns for charging further includes wireless charging, the charging module includes a transmitting coil, and the cleaning robot 100 includes a receiving coil, to charge the cleaning robot 100 through electromagnetic induction between the transmitting coil and the receiving coil. The charging module is disposed on the base station 200, whose beneficial effect lies in that functions of the base station 200 are integrated, so that the base station 200 is reusable in function and compact in structure.
In still another embodiment of the present disclosure, as shown in
As shown in
In this embodiment, the base station 200 is a mopping module replacement station configured to automatically replace a mopping module of the cleaning robot 100, and is also a charging station configured to charge the cleaning robot 100. When the power level of the cleaning robot 100 is insufficient, the cleaning robot 100 may automatically return to the base station 200 for charging, to replenish electric energy. Functions of charging and replacing a mopping module are integrated in the same base station 200, to reduce the costs, and docking sites are reduced, to make it convenient for the user to operate or observe the cleaning robot 100. Certainly, in another embodiment, the base station 200 may be alternatively only a mopping module replacement station.
The base station 200 includes a base 253, a charging module disposed on the base 253 and configured to charge the cleaning robot 100, a storage module 210 is configured to store mopping modules of the cleaning robot 100, a transfer module configured to drive a mopping module 310 to move, and a control unit configured to control the transfer module to autonomously drive the mopping module 310 to move to automatically replace a mopping module 310.
In this embodiment, the storage module 210 is disposed above the base 253, and the storage module 210 and the base 253 enclose an accommodation cavity 258 configured to accommodate the cleaning robot, where the storage module 210 is located above the accommodation cavity 258. In another embodiment, the storage module 210 may be alternatively disposed at another position on the base 253, for example, behind or beside the base station 200. The charging module includes charging terminals configured to dock to and charge the cleaning robot 100. The base station 200 includes a base plate 2531 and a supporting portion configured to connect the base plate and the storage module 210.
The storage module 210 includes a storage module 215 configured to accommodate a mopping module 310. In this embodiment, the base station 200 is a mopping module replacement station configured to automatically replace a mopping module. When mopping module replacement is performed, a new (clean) mopping module is required, and a dirty mopping module is generated. In this case, the storage module configured to accommodate these mopping modules is required. Therefore, the storage module is disposed to accommodate the mopping modules, to automatically replace a mopping module.
In this embodiment, the cleaning robot 100 may automatically return to the base station 200, and automatically replace a mopping module, the dirty mopping module is automatically accommodated in the storage module 210, a clean mopping module 310 is automatically accommodated in the storage module, and the entire process is automatic without any manual operation. However, when the storage module 210 is fully loaded with dirty mopping modules 310, or clean mopping modules 310 are used up, it is very difficult for the user to find this case in time. If the case is not found in time, because the storage module is fully loaded with dirty mopping modules or clean mopping modules are in short supply, the robot cleaning system 300 cannot automatically replace a mopping module, and cannot continue to perform automatic mopping work.
In this embodiment, the base station 200 further includes a storage state detection module configured to detect whether a storage state in the storage module 215 is a preset state and a reminding module configured to send reminding information indicating that the storage state in the storage module 215 is the preset state, and the control unit controls, according to a detection result of the storage state detection module, the reminding module to send the reminding information to the outside. The storage state in the storage module 215 is a state such as whether there is a mopping module in the storage module 215 and/or whether a storage quantity of mopping modules exceeds a preset value. The preset state is a pre-delivery or user-defined threshold state. For example, a state that there is a mopping module in the storage module 215 may be defined as the threshold state, and when the storage state detection module detects that there is a mopping module in the storage module, the control unit controls the reminding module to send the reminding information; or a state that there is no mopping module in the storage module 215 may be defined as the threshold state, and when the storage state detection module detects that there is no mopping module in the storage module, the control unit controls the reminding module to send the reminding information; or a state that the quantity of mopping modules in the storage module 215 reaches the preset value may be defined as the threshold state, and when the storage state detection module detects that the quantity of mopping modules in the storage module reaches the preset value, the control unit controls the reminding module to send the reminding information.
The reminding module may be a light warning apparatus, a sound warning apparatus, a wireless sending module that is configured to send the reminding information to the outside, or the like. For example, the reminding module may emit corresponding light, flashlight, or the like through the light warning apparatus, may alternatively send a warning sound through the sound warning apparatus, and may alternatively send reminding information to a mobile phone app, a computer, or another mobile device of the user through the wireless sending module.
As shown in
The storage module 210 includes a first storage unit 211 and a second storage unit 212 respectively configured to store a dirty mopping module 310 and store a clean mopping module 310, and correspondingly, the storage module 215 includes a first storage unit 2153 configured to store a dirty mopping module and a second storage unit 2154 configured to store a clean mopping module. The communicating mouth 2150 includes a first communicating mouth 2151 and a second communicating mouth 2152 that are respectively located below the first storage unit 2153 and the second storage unit 2154 and that may be opened and closed. The first storage unit 2153 and the second storage unit 2154 are located abreast above the accommodation cavity 258 in the horizontal direction. The corresponding base plate 2531 has an accommodation groove configured to accommodate the dirty mopping module and an accommodation groove configured to accommodate the clean mopping module. In an aspect, the mopping modules may be limited, and in another aspect, the mopping modules may be prevented from excessively protruding from the base plate 2531, to hinder the cleaning robot 100 from moving.
The accommodation cavity 258 has an opening 255 in communication with the outside provided for the cleaning robot 100 to leave and/or enter, and a supporting portion 2532 is disposed on a side of the base station 200 opposite to the opening 255, so that when the cleaning robot 100 docks, projections of the cleaning robot 100 and the storage module 210 in the horizontal plane approximately coincide. Therefore, the structure of the base station 200 in the horizontal direction is more compact, thereby reducing the occupied area of the entire robot cleaning system 300. The charging terminals are located on the supporting portion 2532 or the base plate 2531. Certainly, in some embodiments, the charging terminals may be alternatively located at a position such as the bottom of the storage module 210, so that the top of the cleaning robot 100 is in contact with the charging terminals to perform charging. After entering the base station 200 to complete docking, the cleaning robot 100 starts charging, and the cleaning robot 100 leaves the base station 200 after the charging ends. In another embodiment, a manner in which the cleaning robot 100 returns for charging further includes wireless charging, the charging module includes a transmitting coil, and the cleaning robot 100 includes a receiving coil, to charge the cleaning robot 100 through electromagnetic induction between the transmitting coil and the receiving coil. The charging module is disposed on the base station 200, whose beneficial effect lies in that functions of the base station 200 are integrated, so that the base station 200 is reusable in function and compact in structure.
The storage state detection module 360 may be a mechanical detection structure, a detection sensor, or the like. As shown in
When the storage module 310 includes a first storage unit 211 and a second storage unit 212 respectively configured to store a dirty mopping module 310 and store a clean mopping module 310, each of the first storage unit 211 and the second storage unit 212 includes a storage state detection module 360. As shown in
Specifically, the second storage unit 212 of the base station 200 includes a storage state detection module 360, capable of detecting a current state of the mopping module 310 in the second storage unit 212 and sending reminding information to the user. For example, when it is detected that the second storage unit has no mopping module 310, the user is reminded to add a mopping module in time, to avoid affecting working stability of the base station 200. Similarly, the first storage unit 211 also includes a storage state detection module 360, configured to send reminding information for processing mopping modules 310 to the user when it is detected that the quantity of mopping modules 310 placed in the first storage unit 211 reaches a preset value, or detected that a storage time of mopping modules in the first storage unit 211 reaches a preset value. For example, when the quantity of mopping modules 310 is greater than or equal to a preset value, reminding information for processing the mopping modules 310 is sent to the user. The foregoing preset value may be set before pre-delivery, and may be alternatively set autonomously according to a requirement of the user.
A manner in which the base station sends reminding information includes: the base station communicates with a mobile device (for example, a mobile phone, a computer, or an IPAD), to send reminding information to the user, to remind the user to clear the base station in time, or remind the user to add a mopping module. In another embodiment, the base station includes an indicator, and is capable of reminding, through light or sound of the indicator or in another manner, the user to perform a corresponding operation on the base station.
In another embodiment, as shown in
The transmit end may be disposed on a side of the storage module, the receive end is disposed at a corresponding position on another side of the storage module, and when a signal transmitted by the transmit end can be received by the receive end, it indicates that there is no obstacle between the transmit end and the receive end. If whether the first storage unit 2153 is fully loaded with mopping modules 310 needs to be detected, the transmitter of the photoelectric sensor is mounted on a side of the top of the first storage unit 2153, and the receiver of the photoelectric sensor is mounted at another side; and if the first storage unit 2153 is fully loaded with mopping modules 310, when the transmitter transmits a signal, because the signal is blocked by the mopping module 310 at the top of the first storage unit 2153, the receiver cannot receive the signal, and it is determined accordingly that the first storage unit 2153 has been fully loaded with mopping modules 310. Moreover, if whether the first storage unit 2154 further has a mopping module 310 with which the cleaning robot 100 may perform replacement needs to be detected, the transmit end of the photoelectric sensor is mounted on a side of the bottom of the first storage unit 2154, and the receive end is mounted at a corresponding position on another side; and if the first storage unit 2154 has no mopping module 310 to be mounted, after the transmit end of the photoelectric sensor transmits a signal, because the signal is not blocked by any intermediate mopping module, the receive end can receive the signal, and it is determined accordingly that the first storage unit 2154 has no mopping module 310 that may be provided for the cleaning robot 100 to mount. In another embodiment, the photoelectric sensor may be mounted on another position. For example, if it is determined that the quantity of mopping modules 310 in the storage module 215 is less than 2, the photoelectric sensor may be mounted at a position where a second mopping module is stacked in the storage module 210; and if the receive end has not detected any signal, it indicates that the quantity of mopping modules 310 in the storage module is greater than or equal to 2; otherwise, it indicates that the quantity of mopping modules 310 in the storage module is less than 2.
Certainly, in another embodiment, the storage state detection module may be further a Hall sensor, an infrared sensor, a reed switch, or the like.
Technical features of the foregoing embodiments may be randomly combined. To make description concise, not all possible combinations of the technical features in the foregoing embodiments are described. However, the combinations of these technical features shall be considered as falling within the scope recorded by this specification provided that no conflict exists.
The foregoing embodiments only describe several implementations of the present disclosure, and their description is specific and detailed, but cannot be understood as a limitation to the patent scope of the present disclosure. It should be noted that a person of ordinary skill in the art may further make several variations and improvements without departing from the concept of the present disclosure, and these variations and improvements all fall within the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be subject to the appended claims.
