In some embodiments, the cleaning performing device 1 may move up and down under an action of the driving device 2 according to an actual need, such that improves an adaptability of the cleaning apparatus. Moreover, the position of the cleaning performing device 1 during moving up and down may be constrained by the constraining structure, such that improves a stability of the cleaning performing device 1 during moving up and down.
In some embodiments, the cleaning driving module 12 includes a cleaning power source 121, and a cleaning transmitting mechanism 122, and the cleaning transmitting mechanism 122 is configured to connect between the cleaning power source 121 and the cleaning module 11 to transmit motion, and bring the cleaning module 11 to move under a driving of the cleaning power source 121. In some embodiments, the cleaning transmitting mechanism 122 is arranged in a transmitting box 123.
In some embodiments, the cleaning driving module 12 is not limited to the above form, the cleaning driving module 12 may have other form as long as it can drive the cleaning module 11 to move.
In some embodiments, the cleaning module 11 is driven by the cleaning driving module 12 to rotate relative to the ground around a vertical axis to clean the ground. Of course, the cleaning module 11 is not limited to a specific form, and a movement mode of the cleaning module 11 is also not limited to a form as shown in
In some embodiments, the driving device 2 includes a power source 20 and a transmitting mechanism, and the transmitting mechanism is connected between the power source 20 and the cleaning performing device 1 to transmit motion.
The transmitting mechanism includes a gear 21, and the cleaning performing device 1 includes a rack 13 engaged with the gear 21. When the gear 21 rotates in a first direction, the rack 13 is driven by the gear 21 to move upward. When the gear 21 rotates in a second direction opposite to the first direction, the rack 13 is driven by the gear 21 to move downward. With a cooperation of the rack 13 and the gear 21, the cleaning performing device 1 may move up and down stably.
The power source 20 can be, but is not limited to, a motor. The power source 20 is installed on a fixing base T. The fixing base T may be integrally formed in the body of the cleaning apparatus, or may be fixedly connected to the body directly or indirectly.
In some embodiments, the gear 21 may be directly connected to an output end of the power source 20, or may be indirectly connected to an output end of the power source 20. In an example as shown in
In some embodiments, the rack 13 may be integrally formed on a component of the cleaning performing device 1 (ie, the rack 13 and the component is regarded as one part), or may be fixedly connected to a component of the cleaning performing device 1. For example, when the cleaning performing device 1 includes the transmitting box 123, the rack 13 may be integrally formed with the transmitting box 123 or fixedly connected to the transmitting box 123.
In some embodiments, the constraining structure includes a linkage structure 7. The linkage structure 7 is connected between the cleaning performing device 1 and a fixing structure, and has a fixed trajectory. The linkage structure 7 is linked to move to constrain the position of the cleaning performing device 1 during moving up and down. A trajectory of the rack 13 is matched with the fixed trajectory of the linkage structure 7. Since the trajectory of the linkage structure 7 as the constraining structure is matched with the trajectory of the rack 13 moving along the gear 21, the rack 13 may be constrained to always engage with the gear 21 during a movement of the rack 13, thereby ensuring that the cleaning performing device 1 can move up and down stably. The fixing structure may be, but is not limited to, the fixing base on which the power source 20 is arranged, the fixing structure may also be a relatively fixed structure. In the present disclosure, the linkage structure 7 may move relative to the cleaning performing device 1 during the cleaning performing device moving up and down.
It should be noted that the position where the linkage structure 7 is connected to the cleaning performing device 1 is not limited. In a specific example, the linkage structure 7 is connected to a side wall of the rack 13.
Further, the rack 13 is an arc-shaped rack. The linkage structure 7 with a fixed trajectory is configured to constrain the cleaning performing device 1 to swing up and down, so that the cleaning performing device 1 may change between an upward state and a downward state to generate a position deviation (along an up and down direction).
Further, the linkage structure 7 is movably connected to the cleaning performing device 1 and the fixing structure, and the linkage structure 7, the cleaning performing device 1 and the fixing structure cooperatively form a multi-linkages structure. Specifically, the linkage structure 7 includes a first connecting rod 71 located on an upper side of the linkage structure 7 and a second connecting rod 72 located on a lower side of the linkage structure 7. Both ends of the first connecting rod 71 are hinged to the cleaning performing device 1 and the fixing structure respectively. Both ends of the second connecting rod 72 are hinged to the cleaning performing device 1 and the fixing structure respectively, and the multi-linkages structure is a parallelogram linkage structure. Through this technical mean, the cleaning performing device 1 may be constrained to swing up and down reliably.
In some embodiments, a connecting position of the cleaning performing device 1 and the first connecting rod 71 is vertically opposite to a connecting position of the cleaning performing device 1 and the second connecting rod 72. A connecting position of the fixing structure and the first connecting rod 71 is exactly opposite to a connecting position of the fixing structure and the second connecting rod 72 in a vertical direction. Through this technical mean, the cleaning performing device 1 can maintain a same posture during moving up and down to avoid a skew.
The linkage structure 7 is not limited to the above-mentioned form, the linkage structure 7 can be other structure as long as it can constrain the cleaning performing device 1 to move up and down stably. Further, in order to ensure the reliability of the cooperation between the gear 21 and the rack 13, the linkage structure 7 may include two groups of linkage structure respectively arranged on opposite sides of the gear 21 and the rack 13, but the linkage structure 7 may also have other kinds of structures. In some embodiments, the cleaning assembly further includes an elastic structure (not shown) acting on the linkage structure 7. When the cleaning performing device 1 moves upward, the elastic structure is configured to store an elastic potential energy, and when the cleaning performing device moves downward, the elastic structure is configured to release the elastic potential energy. In this way, when cleaning the ground, etc., the cleaning apparatus may float on the uneven ground, and have a shock absorption effect at the same time.
In some embodiments, the constraining structure may include a swinging arm, a first end of the swinging arm is connected with the cleaning performing device 1, and a second end of the swinging arm is rotatably connected to the fixing structure. During the cleaning performing device 1 moving up and down, the swinging arm is configured to constrain a trajectory of the cleaning performing device 1 of swing up and down.
In order to ensure the reliability of the up and down movement of the cleaning performing device 1, the constraining structure may include other structures, or may be replaced by other structures with a trajectory constraining effect, in addition to the linkage structure 7 and the swinging arm. For example, the constraining structure may include other different structures having a trajectory constraining effect.

In some embodiments, the cleaning performing device 1 can move up and down under an action of the driving device 2 according to an actual need, such that improves an adaptability of the cleaning apparatus. Moreover, the position of the cleaning performing device 1 during moving up and down can be constrained by the constraining structure, such that improves a stability of the cleaning performing device 1 during moving up and down.

In some embodiments, the driving device 2 includes a power source 20 and a transmitting mechanism, and the transmitting mechanism is connected between the power source 20 and the cleaning performing device 1 to transmit motion. The transmitting mechanism includes a moving member 22 capable of moving up and down. When moving upward, the moving member 22 is configured to lift the cleaning performing device 1 upward. When the moving member 22 moves downward, the cleaning performing device 1 loses its support and falls backward. Specifically, the power source 20 may be, but is not limited to, a motor.
In some embodiments, the power source 20 can be installed on a fixing base T, and the fixing base T may be integrally formed in the body of the cleaning apparatus, or may be fixedly connected to the body directly or indirectly. An output end of the power source 20 is connected with a screw rod 23, and the moving member 22 is threadedly matched with the screw rod 23. When the screw rod 23 rotates under a driving of the power source 20, the moving member 22 may move up and down to lift up the cleaning performing device 1, or the cleaning performing device 1 loses its support. The moving member 22 may have a single-piece structure or may be a combination of at least two structures. For example, the moving member 22 may include a main structure and a screw nut fixedly connected to the main structure, and the moving member 22 is matched to the screw rod 23 through the screw nut.
In some embodiments, the constraining structure includes a linkage structure 7 connected between the cleaning performing device 1 and a fixing structure. During the cleaning performing device 1 moving up and down, the linkage structure 7 is linked to move to constrain the position of the cleaning performing device 1. With the arrangement of the linkage structure 7, the position of the cleaning performing device 1 during moving up and down can be constrained, so as to ensure the stability of the up and down movement of the cleaning performing device 1. The fixing structure may be, but is not limited to, the fixing base T. Of course, the linkage structure 7 may be arranged at different positions, and the number of the linkage structure 7 is also not limited.
In some embodiments, the linkage structure 7 is configured to move in a fixed trajectory to constrain a movement up and down of the cleaning performing device 1 with a fixed trajectory. Of course, the linkage structure 7 is not constrained to move with the fixed trajectory.
In some embodiments, constraints of the linkage structure 7 to the cleaning performing device 1 allows the cleaning performing device 1 to swing during moving up and down, thereby causing the cleaning performing device 1 to generate a positional deviation when changing between the upward state and the upward state state.
In some embodiments, the linkage structure 7 is movably connected with the cleaning performing device 1 and the fixing structure, and the linkage structure 7, the cleaning performing device 1 and the fixing structure form a multi-linkages structure.
Further, the linkage structure 7 includes a first connecting rod 71 located on an upper side of the linkage structure 7 and a second connecting rod 72 located on a lower side of the linkage structure 7.

With this technical mean, the cleaning performing device 1 can be constrained to move up and down reliably in a swinging manner.
In some embodiments, a connecting position of the cleaning performing device 1 and the first connecting rod 71 is vertically opposite to a connecting position of the cleaning performing device 1 and the second connecting rod 72. A connecting position of the fixing structure and the first connecting rod 71 is exactly opposite to a connecting position of the fixing structure and the second connecting rod 72 in a vertical direction. Through this technical mean, the cleaning performing device 1 can maintain a same posture during moving up and down to avoid a skew.
Of course, the linkage structure 7 is not limited to the above-mentioned form, the linkage structure 7 can be other structure as long as it can constrain the cleaning performing device 1 to move up and down stably. Specifically, in the case where the cleaning driving module 12 of the cleaning performing device 1 includes a transmitting box 123, the linkage structure 7 may be connected to the transmitting box 123. In order to facilitate the connection of the linkage structure 7 and the transmitting box 123, the transmitting box 123 may have a mounting part 1231 protruded from a side of the transmitting box 123. Of course, a manner of connecting the linkage structure 7 to the cleaning performing device 1 is not limited, as long as the manner can play a role in constraining the position of the cleaning performing device 1 during moving up and down. In some embodiments, the cleaning assembly further includes an elastic structure (not shown) acting on the linkage structure 7. When the cleaning performing device 1 moves upward, the elastic structure stores an elastic potential energy, and when the cleaning performing device moves downward, the elastic structure releases the elastic potential energy. In this way, when the cleaning apparatus cleans the ground, etc., the cleaning apparatus may float on the uneven ground, and have a shock absorption effect at the same time.
It should be noted that the driving device 2 may also act on the linkage structure 7, and may be configured to drive the cleaning performing device 1 to move up and down through the linkage structure 7.
In some other embodiments, the constraining structure may include a swinging arm, one end of the swinging arm is connected with the cleaning performing device 1, and the other end of the swinging arm is rotatably connected to a fixing structure. During the cleaning performing device 1 moving up and down, the swinging arm is configured to swing to constrain a trajectory of the cleaning performing device 1 to swing up and down. The driving device 2 may also be configured to bring the cleaning performing device 1 to move up and down through driving the swinging arm.
In order to ensure the reliability of the up and down movement of the cleaning performing device 1, the constraining structure may include other structures, or may be replaced by other structures with a trajectory constraining effect, in addition to the linkage structure 7 and the swinging arm. For example, the constraining structure may include other different structures having a trajectory constraining effect in other embodiments.

In some embodiments, the driving device 2 includes a power source 20 and a transmitting mechanism, and the transmitting mechanism is connected between the power source 20 and the cleaning performing device 1 to transmit motion. The transmitting mechanism includes a moving member 34 driven by the power source 20 to perform a reciprocating linear movement. The moving member 34 includes a first sliding part, and the cleaning performing device 1 includes a second sliding part matched with the first sliding part. When the moving member 34 moves in the first direction, the first sliding part slides relative to the second sliding part, and the second sliding part moves upward along a direction angled with the first direction under the constraints of the constraining structure. Through the cooperation between the first sliding part on the moving member 34 and the second sliding part on the cleaning performing device 1, the cleaning performing device 1 can move up and down under the action of the power source 20. It should be noted that the constraining structure can constrain a movement up and down of the cleaning performing device 1 with the fixed trajectory, but it is not limited to this.
In some embodiments, the first sliding part includes a first sliding surface 341, the second sliding part includes a first protruding portion 1237. When the first sliding surface 341 moves in the first direction, the first protruding portion 1237 slides along the first sliding surface 341 upward in a direction angled with the first direction.
Further, the moving member 34 defines a first sliding groove 342, the first sliding groove 342 includes a first sliding surface 341 and a third sliding surface 343 opposite to the first sliding surface 341 along an extending direction of the first sliding groove 342. The first protruding portion 1237 is slidably received in the first sliding groove 342. When the third sliding surface 343 moves in the second direction opposite to the first direction, the first protruding portion 1237 slides along the third sliding surface 343 to move downward along a direction angled with the second direction. The first protruding portion 1237 is slidably disposed in the first sliding groove 342, which is beneficial to mating the first protruding portion 1237 with the first sliding groove 342 reliably.
In some embodiments, the cleaning performing device 1 includes a transmitting box 123, and the transmitting box 123 is provided with a first protruding portion 1237 protruded from a side of the transmitting box 123. Of course, the first protruding portion 1237 is not limited to the specific manner.
Of course, the first sliding part and the second sliding part are not limited to the above-mentioned forms. For example, the first sliding part includes a second protruding portion, the second sliding part includes a second sliding surface. The second protruding portion moves in the first direction, and the second sliding surface moves upward in a direction angled with the first direction. Further, the cleaning performing device defines a second sliding groove, the second sliding groove includes a second sliding surface and a fourth sliding surface opposite to the second sliding surface along an extending direction of the second sliding groove, and the second protruding portion is slidably arranged in the second sliding groove. When the protruding portion moves in the second direction opposite to the first direction, the fourth sliding surface moves downward in a direction angled with the second direction. Alternatively, the first sliding part and the second sliding part may also be a cam and a cam mating surface, respectively.
In some embodiments, an output end of the power source 20 is connected with a screw rod 35, and the screw rod 35 is threadedly connected with the moving member 34. When the screw rod 35 rotates under the driving of the power source 20, the moving member 34 may be driven to perform the reciprocating linear movement (In some instances a linear movement in the horizontal direction), the first sliding part moves relative to the second sliding part correspondingly, so that the cleaning performing device 1 moves up and down. The moving member 34 may be a single-piece structure or a combination of at least two structures. For example, the moving member 34 may include a main structure and a screw nut fixedly connected to the main structure, and the moving member 24 is matched to the screw rod 25 through the screw nut.
It can be understood that the linear reciprocating movement of the moving member 34 is not limited to be transmitted by the screw rod 35, and the screw rod 35 can be replaced by other structure which can enable the moving member 34 to perform the linear reciprocating movement.
In some embodiments, the power source 20 may be installed on a fixing base T, and the fixing base T may be integrally formed in the body of the cleaning apparatus, or may be fixedly connected to the body directly or indirectly.
In some embodiments, the constraining structure includes a first structure arranged on the cleaning performing device 1 and a second structure having a fixing structure, the first structure is matched with the second structure. During the cleaning performing device 1 moving up and down, the first structure moves up and down relative to the second structure, and the second structure is configured to constrain the position of the first structure during moving up and down. During the cleaning performing device 1 moving up and down, the first structure is regarded as a component of the cleaning performing device 1 or as a structure fixedly connected to the cleaning performing device 1, and moves up and down relative to the second structure. During the first structure moving up and down, the second structure can constrain the position of the first structure during moving up and down, thus enabling the cleaning performing device 1 to move stably.
In some embodiments, the first structure is slidably matched with the second structure to guide the up and down movement of the cleaning performing device 1. Of course, the first structure is not limited to slidably matched with the second structure. For example, during the first structure moving up and down, the second structure does not necessarily contact with the first structure, and the second structure may constrain a possible deviation of the first structure within a certain range. Alternatively, the first structure or the second structure is used as a component of the transmitting mechanism, and moves under the driving of the power source 20, so that the first structure moves up and down under the action of the second structure, so that the cleaning performing device 1 moves up and down, and the second structure may constrain the position of the first structure in the up and down movement. By the above technical means, the functions of moving up and down and constraining the position of the cleaning performing device 1 are simultaneously achieved by a set of structures, no need to arrange the driving device 2 additionally. For example, the first structure is engaged with the second structure, and during the cleaning performing device 1 moving, up and down, the first structure remains to be engaged with the second structure to guide the cleaning performing device 1 to move up and down. For example, the first structure may include a gear, the second structure may include two racks with fixing structures that are engaged with both sides of the gear respectively. The power source 20 is fixedly connected to the cleaning performing device, and directly or indirectly drives the gear. Under the driving of the power source 20, the gear can move up and down along the two racks, to bring the cleaning performing device 1 and the power source 20 to move up and down. For another example, the first structure may include two oppositely arranged racks, the second structure may include a gear, the two racks are engaged on two opposite sides of the gear, the gear is directly or indirectly connected to the power source 20, and the gear is driven by the power source 20 to bring the two racks and the cleaning performing device to move up and down. During the up and down movements of the racks, the positions of the two racks can be constrained by the gear, and then the position of the cleaning performing device 1 during moving up and down can be constrained. Of course, when the first structure is engaged with the second structure, the first structure or the second structure is not limited to be used as a component of the transmitting mechanism to drive the cleaning performing device to move up and down, or the first structure or the second structure may not be used as a component of the transmitting mechanism. For example, the gear in the above example may drive the cleaning performing device to move without the driving of the power source 20, and the cooperation of the gear and the racks is configured to guide the cleaning performing device to move up and downward, not to drive the cleaning performing device.
In some embodiments, the first structure is a protruding portion 1238 arranged on the cleaning performing device 1, the second structure is a limiting groove 8 provided on a fixing structure, and the protruding portion 1238 is received in the limiting groove 8. When the cleaning performing device 1 moves up and down, the protruding portion 1238 can move up and down in the limiting groove 8, and inner walls of the limiting groove 8 can limit the position of the protruding portion 1238 during moving up and down. Further, the limiting groove 8 may be a sliding groove, and the protruding portion 1238 moves up an down (such as moves upward vertically) along a fixed track under the restriction of the sliding groove. Of course, the protruding portion 1238 does not have to be strictly limited by the limiting groove 8. For example, a width of the limiting groove 8 may be greater than a width of the protruding portion 1238, and the inner walls of the limiting groove 8 can limit a deviation range of the protruding portion 1238 during moving up and down. The fixing structure may be a fixing base T.
When the first structure is slidably matched with the second structure, the matching manner is not limited to a matching of the protruding portion 1238 and the sliding groove, and may include any guiding and sliding mode. For example, the matching manner may include a matching manner of the sliding groove and the sliding wheel, and a matching manner of the sliding groove and the sliding surface, a matching manner of a shaft and a shaft sleeve, and so on.
In some embodiments, the cleaning driving module 12 of the cleaning performing device 1 includes a transmitting box 123, and the first structure is protruded outward from the transmitting box 123. Of course, the structure of the cleaning driving module 12 is not limited to this.
In order to ensure the reliability of the up and down movement of the cleaning performing device 1, the constraining structure may include other structures, or may be replaced by other structures with a trajectory constraining effect, in addition to the linkage structure 7 and the swinging arm. For example, the constraining structure may include other different structures having a trajectory constraining effect in other embodiments.

When the winding wheel 36 rotates in the second direction opposite to the direction, the winding belt 37 becomes loose, and the cleaning performing device 1 falls back under the constraints of the constraining structure. By winding the winding belt 37 on the winding wheel 36, loosening the winding belt 37 from the winding wheel 36, and combining the constraints of the constraining structure, the cleaning performing device 1 may move up and down stably.

The rotary driving motor is in the shape of a lying down cylinder. The plurality of reinforcing ribs 2135 and the extension plate 2136 respectively have an arc surface H that fits with the cylindrical surface of the rotary driving motor 211. By means of this technical means, the structural strength of the constraining structure can be further strengthened, and at the same time, the installation stability of the constraining structure and the compactness of the overall structure of the constraining structure can be facilitated.
