Description

BACKGROUND

Technical Field

The present disclosure relates to the field of electromechanical technologies, and in particular, to a self-moving robot system.

Related Art

A base station of a conventional self-moving robot is mainly configured to charge the self-moving robot, and a user needs to dump and clean a dust containing box of the self-moving robot. In order to reduce a user intervention frequency, a “suction type” dust collection base station is introduced, and an air pump is mounted in the dust collection base station to suck away debris in the dust containing box of the self-moving robot.

At present, during operation of the “suction type” dust collection base station, there is a common problem of loud noise with a noise level even reaching 75 dB, far exceeding a level of 40 dB to 60 dB for normal people's conversation, which affects the normal conversation of users and makes people feel upset and distracted. The dust collection base station performs a suction operation every time the self-moving robot returns to the base station, and frequent suction with loud noise causes discomfort to the user and damages the hearing nerve.

DETAILED DESCRIPTION

Exemplary implementations of the present embodiments are described below in detail with reference to the accompanying drawings. It should be understood that these detailed descriptions are merely used for teaching a person skilled in the art to implement the present embodiments, but are not used to exhaust all possible manners of the present embodiments and are not used for limiting the scope of the present embodiments.

As shown in FIG. 1-1 to FIG. 1-4 and FIG. 2-1 to FIG. 2-3, the present disclosure provides a self-moving robot system, including a self-moving robot 2 (for example, a sweeping robot) and a dust collection base station 1. The self-moving robot 2 includes a main machine 21 and a dust containing box 22. The dust containing box 22 is detachably mounted on the main machine 21, the dust containing box 22 is configured to accommodate debris 3, dust, and the like, and the main machine 21 includes a circuit part of the self-moving robot 2.

The dust collection base station 1 includes a charger 18, a power mechanism (not shown), a dust collector 16, and a transfer 13. The self-moving robot 2 includes a charging connector 28, and the charger 18 is configured to electrically connect the charging connector 28, to charge the self-moving robot 2. The charger 18 may include a metal contact, and the charging connector 28 may include a metal contact matching the metal contact of the charger 18.

The transfer 13 can be engaged with the dust containing box 22 and assist separation of the dust containing box 22 from the main machine 21 or assist mounting of the dust containing box 22 on the main machine 21. For example, a lock pin 27 is driven to exit from a lock slot, so that the dust containing box 22 is separated from the main machine 21, or the dust containing box 22 is loosened, and the lock pin 27 is inserted into the lock slot, so that the dust containing box 22 is mounted on the main machine 21.

It should be understood that that the transfer 13 “assists” the separation of the dust containing box 22 from the main machine 21 includes the following two cases:

First, the dust containing box 22 is disassembled and removed from the main machine 21 by the transfer 13.

Second, the dust containing box 22 is actively unloaded by the main machine 21, for example, ejected out from the main machine/pushed out by the main machine, and the transfer 13 is configured to receive and move the dust containing box 22 separated from the main machine 21.

The power mechanism is connected to the transfer 13, so that the transfer 13 moves according to a predetermined path, to transfer the dust containing box 22 to a dust collection opening of the dust collector 16. The self-moving robot system includes a first cover opener 15, where the first cover opener 15 is mounted on the dust collection base station 1 or the self-moving robot 2. When the dust containing box 22 arrives at the dust collection opening, the first cover opener 15 opens the dust containing box 22, so that the debris 3 and the like in the dust containing box 22 fall into the dust collector 16 from the dust collection opening. When the transfer 13 transfers the dust containing box 22, the charger 18 may be electrically connected to the main machine 21 of the self-moving robot 2, to charge the self-moving robot 2.

In the self-moving robot system, the dust containing box 22 of the self-moving robot 2 can be removed from the main machine 21, and the dust containing box 22 can be moved to the dust collection opening, so that the debris 3 and the like in the dust containing box 22 are collected by the dust collector 16, and the debris 3 and the like are uniformly cleaned, to prevent a user from frequently taking out the debris. In addition, in the system, there is no need to move the entire self-moving robot 2 with a relatively small system load and a relatively low requirement on a driving capability of a driving apparatus. The dust containing box 22 is transferred by the transfer 13 without using an air pump to suck the debris 3 and the like in the dust containing box 22 with relatively low working noise and relatively high use comfort of the user.

In addition, the self-moving robot 2 can be charged synchronously during debris 3 collection and the like.

A direction from which the self-moving robot 2 enters the dust collection base station 1 is defined as an entrance direction I, and a direction from which the self-moving robot leaves the dust collection base station 1 is defined as an exit direction O.

Two specific embodiments of the self-moving robot system are respectively described below.

First Embodiment

As shown in FIG. 1-1 to FIG. 1-4, the power mechanism includes a conveying assembly, where the conveying assembly includes a first conveying portion arranged in a vertical direction and a second conveying portion arranged in a horizontal direction, and the transfer is connected to the power mechanism to move along with the conveying assembly. The conveying assembly includes a synchronous belt assembly, the first conveying portion includes a first synchronous belt, and the second conveying portion includes a second synchronous belt.

The power mechanism may include a driving motor (not shown). The driving motor drives the synchronous belt assembly, and the synchronous belt assembly includes a synchronous belt 11 and a roller, where the synchronous belt 11 is mounted on the roller, and the roller is driven by the driving motor to drive the synchronous belt 11. The synchronous belt 11 includes a first synchronous belt 111 arranged in a vertical direction and a second synchronous belt 112 arranged in a horizontal direction.

In another implementation, the power mechanism may further include another structure such as a gear and rack mechanism, a link mechanism, a steel wire or a chain, or a screw and a screw rod.

For example, the power mechanism includes a rack assembly and a gear assembly mounted on the transfer, and the gear assembly meshes with the rack assembly and rotates to drive the transfer to move.

The dust collector 16 may be located beside the first synchronous belt 111 and below the second synchronous belt 112. The transfer 13 may be connected to the synchronous belt assembly, for example, riveted to the synchronous belt 11 or tightly fixed to the synchronous belt 11 through a bolt, so that the transfer 13 can follow the synchronous belt assembly to move to the dust collection opening along the first synchronous belt 111 and the second synchronous belt 112. The dust collection base station 1 includes an operating position for the self-moving robot 2 to stop. The charger 18 may be arranged at the operating position, the dust collector 16 is arranged higher than the charger 18 (the operating position), the self-moving robot 2 enters and exits the dust collection base station 1 below the dust collector 16, and the conveying assembly is located on a lateral upper side of the dust collector 16. When the transfer 13 transfers the dust containing box 22, the dust collector 16 is located above the operating position, so that the structure in the dust collection base station 1 is compact.

The dust collection base station 1 may further include a sealing portion, where the sealing portion is configured to sealedly connect the dust containing box 22 and the dust collection opening, to avoid leakage of dust and the like.

In this embodiment, the sealing portion may include a transfer cover 162, and the dust collector 16 may include a garbage bin 161 and the transfer cover 162, where the garbage bin 161 is provided with the dust collection opening, and the garbage bin 161 may be used with a garbage bag. The transfer cover 162 is provided with a large opening end and a small opening end, an aperture of the large opening end is greater than an aperture of the small opening end, the large opening end of the transfer cover 162 is sleeved with the dust collection opening, and the small opening end is configured to be aligned with the dust containing box 22. When the dust containing box 22 is moved above the dust collector 16, a debris dumping opening of the dust containing box 22 can be engaged with the small opening end of the transfer cover 162, so that when the debris 3 and the like are dumped, there is no dust leakage gap between the dust containing box 22 and the garbage bin 161, to avoid dust raising.

In another embodiment, an air hole may be provided on one side of the garbage bin 161, and a fan is mounted on an outer side wall of the garbage bin 161, so that a space between the garbage bin 161 and the garbage bag may be vacuumized through rotation of the fan, and the garbage bag is placed close to an inner wall of the garbage bin 161 under the action of atmospheric pressure.

In another embodiment, the dust collector 16 may further have a garbage bin mounting position but does not include the garbage bin 161, and the user may directly place a household garbage bin at the mounting position or cover the garbage bin mounting position with a garbage bag.

In another embodiment, the self-moving robot system further includes a transmission mechanism configured to control the dust collector 16 to move. Optionally, the transmission mechanism includes a transmission belt and a driving motor. Optionally, the transmission belt may drive the dust collector to respectively move to a garbage bag mounting position outside the dust collection base station 1, an internal mop recycle position, and a dust collection initial position. Optionally, the dust collection initial position may be located between the garbage bag mounting position and the mop recycle position.

As shown in FIG. 1-13, a full dust detection apparatus 166 such as an infrared sensor, an ultrasonic sensor, or a distance sensor is further mounted on an upper edge of the garbage bin 161. When debris and the like are about to fill up the garbage bin 161, the full dust detection apparatus 166 detects this case and reminds the user to empty the garbage bin.

The dust collection base station 1 may further include a track 121 closely attached to the synchronous belt 11 and a track 122 spaced apart from the synchronous belt 11, where the tracks 121 and 122 may be approximately parallel to the synchronous belt 11. The transfer 13 may be limited by the tracks 121 and 122 to move along the tracks 121 and 122 from a head end to a tail end. The tracks 121 and 122 each may include a first track section 123 parallel to a transmission trajectory of the first synchronous belt 111, a second track section 124 parallel to a transmission trajectory of the second synchronous belt 112, and a descending section 125 connected to the second track section 124. The descending section 125 may be inclined relative to a vertical direction and arranged on a tail end of each of the tracks 121 and 122. The transfer 13 moves in the vertical direction along the first track section 123, moves in the horizontal direction along the second track section 124, and descends along the descending section 125, so that the dust containing box 22 can pass over the transfer cover 162 in height and then descend to be closely attached to the transfer cover 162.

The transfer 13 may include a plurality of rolling bearings 141, where the rolling bearings 141 are mounted in the tracks 121 and 122, so that the transfer 13 is rollably connected to the tracks 121 and 122.

As shown in FIG. 1-3a to FIG. 1-3d, the self-moving robot 2 may include the first cover opener 15, and the first cover opener 15 may be fixedly mounted on the dust containing box 22 of the self-moving robot 2 and is transferred together with the dust containing box 22. The dust containing box 22 includes an upper flip cover 23 and a lower flip cover 24 (a box cover). The upper flip cover 23 is operated manually to open or close the dust containing box 22, and the lower flip cover 24 is operated by a cover opening mechanism to open and close the dust containing box 22. The upper flip cover 23 may be located on an upper surface of the dust containing box 22, and the lower flip cover 24 may be located on a lower surface of the dust containing box 22, to facilitate manual cover opening and automatic cover opening.

The dust containing box 22 may further be provided with a filtering element 220. When the self-moving robot 2 works, the filtering element 220 filters sucked debris. The filtering element 220 may include a high efficiency particulate air (HEPA) filter, a sponge mat, nonwoven fabric, or the like.

The first cover opener 15 includes a cover opening motor and a rotational portion, where the rotational portion may include a synchronous belt wheel 151, a tension wheel 152, and a synchronous belt 153. The synchronous belt wheel 151 may be mounted on an output end of the cover opening motor, the synchronous belt wheel 151 is connected to the tension wheel 152 by the synchronous belt 153, and the cover opening motor drives the rotational portion to rotate, that is, drives the synchronous belt wheel 151 and the tension wheel 152 to rotate and drives the synchronous belt 153 to roll. The cover opening motor may be mounted on the dust containing box 22, and the rotational portion may be mounted on the lower flip cover 24 of the dust containing box 22. The first cover opener 15 and the dust containing box 22 are fixedly mounted, so that the first cover opener 15 is reliably connected to the dust containing box 22. When the dust containing box 22 is moved to the dust collection opening of the dust collector 16, the cover opening motor drives the rotational portion to rotate, so as to open the lower flip cover 24. after the dust containing box 22 completes debris dumping, the cover opening motor drives the rotational portion to rotate, so as to close the lower flip cover 24.

In another embodiment, the first cover opener 15 may further include a linkage mechanism arranged inside the dust containing box 22, and after clamping the dust containing box 22, the transfer 13 opens and closes the lower flip cover 24 by acting on the linkage mechanism.

As shown in FIG. 1-2, a contact electrode may be arranged at a position where the dust containing box 22 corresponds to the transfer 13. When the transfer 13 is engaged with the dust containing box 22, the contact electrode is conducted, so that a power supply of the cover opening motor is turned on, and whether the first cover opener 15 is opened or not may be controlled as required.

As shown in FIG. 1-1 and FIG. 1-2, the transfer 13 includes a power source, a transfer frame 131 and a loading and unloading portion, where the loading and unloading portion is configured to operate the dust containing box 22 to be separated from the main machine 21 or mounted on the main machine 21. The loading and unloading portion may specifically include a clamping claw 138. The transfer frame 131 is mounted on the synchronous belt 11 (the power mechanism), and the power source and the clamping claw 138 are mounted on the transfer frame 131. The power source includes a clamping motor and a gear (a first gear structure), and the clamping claw 138 includes a rack 139 (a second rack structure). The gear driven by the clamping motor meshes with the rack 139, so that the rack 139 drives the clamping claw 138 to clamp or loosen the dust containing box 22.

In this embodiment, the loading and unloading portion is located on the transfer 13. In another embodiment, the loading and unloading portion may further be located on the self-moving robot.

A lock pin 27 and a linkage portion 29 are arranged in the dust containing box 22. When the clamping claw 138 is engaged with the linkage portion 29 and pushes the linkage portion 29 in the horizontal direction, the lock pin 27 can be linked to the linkage portion 29, so as to exit the lock slot. The linkage portion 29 is provided with a locking spring 26 connected to the lock pin 27, and the lock slot is provided on the main machine 21 of the self-moving robot 2. For example, the linkage portion 29 may be located at the downstream of the lock pin 27 in the entrance direction I, and the linkage portion 29 and the lock pin 27 may simultaneously move in two opposite directions in the horizontal direction.

When the transfer 13 is engaged with the dust containing box 22, the clamping claw 138 tightly clamps the linkage portion 29 and may push the linkage portion 29 in the exit direction O. When the linkage portion 29 moves, the locking spring 26 is compressed, and the lock pin 27 is linked to the linkage portion 29 and moves in the entrance direction I to exit the lock slot (as shown in FIG. 1-3b). When the transfer 13 loosens the dust containing box 22, the clamping claw 138 loosens the linkage portion 29, and the lock pin 27 is ejected by an elastic force of the locking spring 26 in the exit direction O, so that the lock pin 27 is inserted into the lock slot (as shown in FIG. 1-3c).

In an embodiment, as shown in FIG. 3-1 and FIG. 3-2, the self-moving robot system includes a second cover opener 4, where the second cover opener 4 includes: a driving member 41, arranged on the loading and unloading portion; and a rotational member 42, arranged on one side of the dust containing box 22 and being in contact with the box cover (that is, the lower flip cover 24) of the dust containing box 22, where the rotational member 42 is configured to rotate between a first position and a second position under the drive of the driving member 41; when the rotational member 42 is located at the first position, the box cover is closed; and when the rotational member 42 rotates from the first position to the second position, the box cover is opened under the drive of the rotational member 42.

Optionally, still referring to FIG. 3-1 and FIG. 3-2, one end of the rotational member 42 is rotatably connected to the dust containing box 22 by a connecting shaft, and one end of the rotational member away from the connecting shaft is in contact with the box cover under the action of gravity. When the rotational member 42 is located at the first position, the box cover is closed; and when the rotational member 42 rotates around the connecting shaft under the drive of the driving member 41 to the second position, one end of the rotational member 42 away from the connecting shaft pushes the box cover to be opened, so that dust in the dust containing box falls into the dust collector 16. Optionally, the rotational member 42 is provided with a limiting portion. When the rotational member 42 is located at the first position, there is a space between one end of the box cover away from the rotational member 42 and the limiting portion, and when the rotational member 42 rotates around the connecting shaft under the drive of the driving member 41 to the second position, one end of the box cover away from the rotational member 42 abuts against the limiting portion, and one end of the rotational member 42 away from the connecting shaft abuts against the box cover, so that the rotational member 42 and the box cover limit each other.

The loading and unloading portion may be provided with the clamping claw 138, and the driving member 41 may be arranged on one side of an end portion of the clamping claw 138 and independent of the clamping claw 138. First, after the clamping claw 138 tightens inward, clamps the dust containing box 22, and transfers the dust containing box to the dust collection opening (a time sequence 2), the driving member 41 may move to one end of the rotational member 42 close to the connecting shaft under an external force (a time sequence 3), to push the rotational member 42 to rotate. After dust in the dust containing box 22 has been dumped, the external force on the driving member 41 is released, to reset the driving member 41 (a time sequence 4), so that the rotational member 42 is reset, that is, the rotational member 42 rotates from the second position to the first position, and when the rotational member 42 rotates back to the first position, the box cover is closed again.

As shown in FIG. 1-3d, the self-moving robot 2 includes an operating portion, where the operating portion can assist separation of the dust containing box 22 from the main machine 21 or mounting of the dust containing box on the main machine 21 in response to pressing or releasing pressing of a user. Specifically, when the dust containing box 22 is manually opened, for example, a button 211 (the operating portion) is pressed in a direction of an arrow A, to compress the locking spring 26, the linkage portion 29 moves and drives the lock pin 27 by using a transfer mechanism 212, and the transfer mechanism 212 causes the linkage portion 29 and the lock pin 27 to be close to each other, for example, the linkage portion 29 moves in a direction of an arrow B2, and the lock pin 27 moves in a direction of an arrow B1, so that the lock pin 27 is retracted and unlocked from the main machine 21.

The dust containing box 22 is provided with an upwardly open engagement groove, and the main machine 21 is provided an upwardly open opening through which the dust containing box 22 is separated from the main machine 21. The clamping claw 138 can enter the engagement groove and tightly clamp the dust containing box 22, and the clamping claw 138 moves vertically along the first synchronous belt 111 after tightly clamping the dust containing box 22.

When the transfer 13 transfers the dust containing box 22, the clamping claw 138 bears the entire weight of the dust containing box 22, and a structure in which the gear meshes with the rack 139 can provide a reliable locking force, thereby ensuring that the dust containing box 22 is stably and reliably transferred.

The clamping claw 138 can apply a force to the dust containing box 22 to cause the lock pin 27 to exit the lock slot, so as to assist separation of the dust containing box 22 from the main machine 21 and can further release the force applied to the lock pin 27 to cause the lock pin 27 to be inserted into the lock slot, so as to assist mounting of the dust containing box 22 on the main machine 21.

The dust collection base station 1 may further include an auxiliary dust dumping apparatus 17 (which is shown in FIG. 2-2), where the auxiliary dust dumping apparatus 17 includes a vibration motor and an eccentric block (an eccentric assembly). The vibration motor drives the eccentric block to vibrate, the vibration motor may be mounted on the transfer frame 131 (the auxiliary dust dumping apparatus 17 is mounted on the transfer 13) and move along with the transfer 13, and the eccentric block can be connected to the dust containing box 22 or in contact with the dust containing box 22, to drive the dust containing box 22 to vibrate. When the dust containing box 22 is transferred to the dust collection opening, the auxiliary dust dumping apparatus 17 slaps the dust containing box 22, to facilitate dumping of the debris 3 and the like.

The auxiliary dust dumping apparatus 17 may further include, for example, four shock-absorbing balls (dampers), where the shock-absorbing ball may be connected between the vibration motor and the transfer 13, for example, connected between the vibration motor and the transfer frame 131. The shock-absorbing ball has a function of shock absorption, to reduce a vibration force transmitted by the vibration motor to the transfer frame 131 and enable the vibration force to act on the dust containing box 22 as much as possible.

The dust collection base station 1 includes a control system, where the control system is configured to control the driving motor, the clamping motor, the cover opening motor, the vibration motor, and the like.
