Detailed Description

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.

A cleaning assembly of a cleaning robot according to an embodiment of the present invention is described below with reference to fig. 1 to 16.

The cleaning assembly 100 according to an embodiment of the present invention includes: the cleaning part 10, the driving assembly 20, the pressing assembly 30 and the reset element 40.

The cleaning part 10 is rotatably disposed at the bottom of the cleaning robot, and the cleaning part 10 is provided with a cleaning surface 10a, wherein the cleaning surface 10a is used for cleaning a cleaning surface, and the cleaning surface can be a ground, a wall surface, a glass surface of a window, and the like. The cleaning assembly 100 of the present application will now be described with reference to the cleaning surface being a floor surface.

The cleaning part 10 cleans the cleaning surface in a rotating manner, when the cleaning part 10 rotates, the cleaning surface 10a also rotates along with the cleaning part, the cleaning surface 10a can be in contact with the cleaning surface, and the cleaning surface 10a cleans the cleaning surface in a rotating manner, so that the cleaning effect is good.

As shown in fig. 1 and 4, the driving assembly 20 is connected to the cleaning part 10, and the cleaning part 10 can slide in a vertical direction with respect to the driving assembly 20, and the driving assembly 20 is fixedly installed on a housing of the cleaning robot and is used to drive the cleaning assembly 100 to rotate, so as to implement a cleaning action of the cleaning part 10.

As shown in fig. 1 and 4, the pressing assembly 30 is connected to the cleaning part 10 and the driving assembly 20, respectively, and the pressing assembly 30 can apply a driving force to the cleaning part 10 to move to the cleaning surface side with respect to the driving assembly 20 when the cleaning part 10 rotates, so as to drive the cleaning part 10 to slide downward with respect to the driving assembly 20, thereby attaching the cleaning part 10 to the cleaning surface and ensuring the cleaning effect of the cleaning part 10.

The cleaning surface comprises a ground, a wall surface, a ceiling, a window glass surface and the like, and the ground can be a horizontal ground or a ground with a certain included angle with the horizontal direction; the wall surface may be a wall surface of a vertically disposed wall. That is, the cleaning assembly 100 of the present application may be applied to a window cleaning machine or a sweeping robot.

It should be noted that, the cleaning assembly 100 may include various working states, taking the cleaning surface as the floor as an example, when the cleaning portion 10 cleans the floor, the cleaning surface 10a may be pressed against the floor by its own gravity, and the driving assembly 20 drives the cleaning portion 10 to rotate so as to further increase the pressure between the cleaning surface 10a and the floor by the pressing assembly 30, thereby ensuring the cleaning effect of the cleaning surface 10a on the floor.

As shown in fig. 7, the reset element 40 is connected between the driving assembly 20 and the cleaning part 10, and the reset element 40 can store energy when the pressing assembly 30 drives the cleaning part 10 to move downward (to the cleaning surface side) with respect to the driving assembly 20, and apply a driving force (reset driving force) to the cleaning part 10 to move upward with respect to the driving assembly 20.

Specifically, the reset element 40 is connected between the driving unit 20 and the cleaning part 10, and when the cleaning part 10 is not rotated, the pressing unit 30 does not apply driving force to the cleaning part 10, and the cleaning part 10 can be fixed at an initial position under the action of the reset element 40; when the cleaning part 10 rotates, the pressing assembly 30 applies a driving force to the cleaning part 10, and the cleaning part 10 moves downward relative to the driving assembly 20 under the driving force, and the restoring member 40 stores energy to drive the cleaning part 10 to move toward the initial position in the case that the driving force is reduced or eliminated.

It should be noted that, the "initial position" refers to a position of the cleaning portion 10 relative to the driving assembly 20 when the cleaning assembly 100 is not in operation.

It will be appreciated that when the cleaning part 10 is not in operation, the cleaning surface 10a is not in contact with the cleaning surface, i.e., the cleaning surface 10a is spaced apart from the cleaning surface, so that the running resistance of the cleaning robot can be reduced, the cleaning robot can be moved conveniently, and a gap can be reserved between the cleaning assembly 100 and the cleaning surface, thereby improving the obstacle surmounting capability of the cleaning robot. When the cleaning portion 10 is required to clean a cleaning surface, the driving assembly 20 is controlled to drive the cleaning portion 10 to rotate, the pressing assembly 30 can apply driving force to the cleaning portion 10 while the cleaning portion 10 rotates, so as to drive the cleaning portion 10 to move downwards relative to the driving assembly 20, so that the cleaning surface 10a is tightly attached to the cleaning surface, the cleaning effect of the cleaning portion 10 on the cleaning surface is ensured, and in the process of moving the cleaning portion 10 downwards relative to the driving assembly 20, the resetting member 40 stores energy until the position of the cleaning portion 10 relative to the driving assembly 20 is not changed. At this time, if the pushing driving force applied to the cleaning portion 10 by the pushing assembly 30 is reduced, the reset element 40 may drive the cleaning portion 10 to move upward relative to the driving assembly 20, i.e. the cleaning portion 10 moves to a side far away from the floor, so as to space the cleaning surface 10a from the floor, so that the cleaning portion 10 is convenient to cross the obstacle on the floor, and the obstacle crossing capability of the cleaning assembly 100 is improved.

The pressing action of the pressing component 30 is performed simultaneously with the rotation of the cleaning portion 10 driven by the driving component 20, when the rotation speed of the cleaning portion 10 is reduced or stagnates due to the blockage of the cleaning portion 10 in the rotation process, the pressing component 30 does not apply a downward driving force to the cleaning portion 10, and under the action of the resetting member 40, the cleaning portion 10 can be quickly reset (i.e. move upwards).

It should be further noted that the cleaning robot is provided with a vision sensor for detecting an obstacle of the cleaning robot on the traveling path, so that the cleaning robot can avoid the obstacle. When the cleaning robot judges that the cleaning part 10 can be lifted up to cross the obstacle, the rotation speed of the driving component 20 for driving the cleaning part 10 can be reduced so as to lift the cleaning part 10, so that the cleaning robot can conveniently cross the obstacle from above, and the cleaning part can smoothly cross the obstacle; when the cleaning robot judges that the obstacle cannot be passed over (the obstacle cannot be passed over even if the cleaning part 10 is lifted up), the traveling direction of the cleaning robot can be adjusted, so that the cleaning robot can avoid the obstacle. The functions of active obstacle crossing and active obstacle avoidance can be realized through the vision sensor, but the situation that the vision sensor does not detect the obstacle due to lower obstacle and the like still exists.

When the cleaning part 10 cleans the floor, the cleaning part 10 is closely attached to the floor to ensure the cleaning effect. In the traveling process of the cleaning robot, when the cleaning part 10 contacts with an obstacle on the ground, the rotation of the cleaning part 10 is blocked, at this time, the cleaning part 10 stops rotating or the rotation speed is greatly reduced, the cleaning part 10 can be quickly reset under the action of the resetting piece 40, that is, the cleaning part 10 is quickly lifted upwards to avoid the obstacle, and the cleaning robot can pass over the obstacle. The cleaning part 10 stops rotating or the rotating speed is greatly reduced by touching the cleaning part 10 or the cleaning surface 10a with the obstacle, so that the passive obstacle crossing function of the cleaning robot can be realized, the response speed of the passive obstacle crossing is high, and the passive obstacle crossing effect of the cleaning robot can be ensured.

Wherein, the driving assembly 20 can be fixed on the shell, the position of the driving assembly 20 relative to the shell is not changed, and because the pressing assembly 30 is respectively connected with the cleaning part 10 and the driving assembly 20, when the pressing assembly 30 applies the driving force to the cleaning part 10 which moves towards the cleaning surface side relative to the driving assembly 20, the cleaning part 10 moves synchronously relative to the shell while moving relative to the driving assembly 20, thereby adjusting the position of the cleaning part 10 relative to the shell.

According to the cleaning assembly 100 of the embodiment of the present invention, the driving assembly 20 can drive the cleaning portion 10 to rotate, and the pressing assembly 30 can drive the cleaning portion 10 to move downward relative to the driving assembly 20, so that the cleaning surface 10a is tightly attached to the cleaning surface, the cleaning effect of the cleaning surface 10a on the cleaning surface is ensured, and the cleaning surface 10a can further improve the cleaning effect of the cleaning assembly 100 on the cleaning surface by applying pressure to the cleaning surface and rotating the cleaning surface. When the traveling direction of the cleaning assembly 100 encounters an obstacle, the cleaning portion 10 can be driven to move upward by the reset member 40, i.e., the cleaning surface 10a is separated from the cleaning surface, so that the cleaning assembly 100 can pass through the obstacle, and the obstacle surmounting capability of the cleaning assembly 100 is improved.

As shown in fig. 4, in some embodiments of the present invention, the cleaning part 10 includes: the cleaning part body 11 and the connecting seat 12, the cleaning part body 11 is provided with the cleaning surface 10a, the connecting seat 12 is arranged on the cleaning part body 11, the connecting seat 12 is positioned at the center of the surface of the cleaning part body 11 on the side away from the cleaning surface 10a, and the connecting seat 12 is connected with the driving assembly 20.

As shown in fig. 1, the driving assembly 20 is connected with the cleaning part body 11 through the connection base 12, so that driving force is transmitted to the cleaning part body 11 through the connection base 12, and since the connection base 12 is disposed at the central position of the cleaning part body 11, when the driving assembly 20 drives the cleaning part 10 to rotate, the cleaning part 10 rotates around the central position thereof, so that stability in the rotation process of the cleaning part 10 can be ensured.

It should be noted that, when the cleaning portion body 11 is configured in a circular shape, the "center position" of the cleaning portion body 11 is the center position of the circular shape, in relation to the shape of the cleaning portion body 11; when the cleaning portion body 11 is configured as a regular polygon, the center position is the center of the regular polygon. Preferably, the cleaning part body 11 is constructed in a circular, regular polygonal, structured pattern, thereby facilitating the determination of the position of the connection base 12 and ensuring the stability during the rotation of the cleaning part 10.

The cleaning surface 10a has a cleaning function, and when the cleaning surface 10a is in fit with the floor, the rotating cleaning surface 10a can clean the floor.

Specifically, the driving member 23 is configured to output a driving force to drive the driving seat 21 to rotate, and the driving seat 21 may drive the connection seat 12 connected thereto to rotate synchronously, thereby driving the cleaning portion 10 to rotate. During the rotation of the cleaning part 10, the cleaning part 10 can slide in the vertical direction relative to the driving seat 21.

Wherein the driving piece 23 is configured as a driving motor, and the driving motor outputs driving force with good stability.

Wherein one of the plug portion 211 and the plug mating portion 121 is configured as a plug bar, and the other of the plug portion 211 and the plug mating portion 121 is configured as a socket. When the connecting seat 12 is connected and matched with the driving seat 21, the inserted rod is inserted into the slot along the vertical direction, and the inserted rod can slide in the slot.

Referring to fig. 1, taking the plug portion 211 as a plug rod and the plug mating portion 121 as a socket as an example, when the cleaning portion 10 moves downward relative to the driving component 20, the connecting seat 12 moves downward relative to the driving seat 21, and at this time, the plug rod slides out of the socket and at least part of the plug rod is still located in the socket, so that the driving component 20 still can transmit the driving force to the connecting seat 12 through the plug rod, and the driving effect of the driving component 20 is ensured.

Referring to fig. 1 and 4, in some embodiments of the present invention, the driving seat 21 is provided with a plurality of insert rods, which are uniformly spaced in a circumferential direction of a rotation axis of the driving seat 21, and the connection seat 12 is provided with a plurality of slots, which correspond to the insert rods one by one. "axis of rotation" refers to: when the driving piece 23 drives the driving seat 21 to rotate, the driving seat 21 rotates around the rotation axis, and the cleaning part 10 can synchronously rotate around the rotation axis. It can be understood that the connection reliability of the connecting seat 12 and the driving seat 21 can be improved by arranging a plurality of groups of inserting rods and inserting slots, and the stability of driving force transmission is ensured, so that the rotation of the cleaning part 10 is more stable, and the cleaning effect of the cleaning part 10 on the ground is further ensured.

Referring to fig. 1, there are two limiting portions 312, the two limiting portions 312 are respectively disposed at two ends of the guide rail 311, and the slider 32 can slide between the two limiting portions 312. When the slider 32 abuts against the stopper 312, the slider 32 cannot further slide relative to the rail 311. The limiting portion 312 includes a first limiting portion 3121 and a second limiting portion 3122, the first limiting portion 3121 is disposed between the slider 32 and the connection seat 12, and the second limiting portion 3122 is disposed on a side of the slider 32 away from the connection seat 12.

In some embodiments of the present invention, the driving manner of the slider 32 may include driving by a driving device and centrifugal force driving, the driving device being connected to the slider 32 and used for driving the slider 32 to slide, so as to pull the connecting member 33 through the slider 32, thereby realizing adjustment of the position of the cleaning part 10; when the cleaning portion 10 is rotated by centrifugal force, the slider 32 has a movement tendency to move toward a side away from the connection base 12, i.e., the slider 32 can perform centrifugal movement.

In a specific embodiment of the present invention, the sliding direction of the slider 32 is the radial direction of the rotation axis, and the extending direction of the guide rail 311 is parallel to the radial direction of the rotation axis. Since the mounting base 31 is disposed on the cleaning part body 11, when the cleaning part 10 rotates, the slider 32 will slide to a side far away from the connecting base 12 under the action of centrifugal force, and during the sliding process of the slider 32, the slider 32 will pull the connecting piece 33, and the connecting piece 33 can apply driving force to the connecting base 12 at this time to drive the connecting base 12 to move downward relative to the driving component 20.

Wherein the centrifugal force is related to the mass of the slider 32, the rotational angular velocity of the cleaning portion 10, and the distance between the slider 32 and the rotational axis. During the rotation of the cleaning part 10, when the rotational angular velocity of the cleaning part 10 and the mass of the slider 32 are constant, the slider 32 moves away from the connecting seat 12 under the action of the centrifugal force, and at this time, the centrifugal force of the slider 32 gradually increases to drive the cleaning part 10 to move downward relative to the driving assembly 20. It will be appreciated that the centrifugal force experienced by the slider 32 may also be adjusted by adjusting the rotational angular velocity of the cleaning portion 10 when adjusting the position of the cleaning portion 10 relative to the drive assembly 20.

As shown in fig. 1 and 4, in some embodiments of the present invention, the upper surface of the connection seat 12 is provided with a via hole 12a, and the other end of the connection member 33 is disposed through the via hole 12a and connected to the driving assembly 20. The two ends of the connecting piece 33 are respectively connected with the driving assembly 20 and the sliding block 32, when the sliding block 32 slides to the side far away from the connecting seat 12, the sliding block 32 pulls the connecting piece 33, and at this time, the connecting piece 33 can apply driving force to the connecting seat 12 and slide relative to the through hole 12 a.

As shown in fig. 4, in a further embodiment of the present invention, an arc surface is formed in the circumferential direction of the via hole 12a, and the connection member 33 abuts against the arc surface, so that the arc surface can reduce the sliding resistance between the connection member 33 and the connection seat 12, prevent the connection member 33 from being damaged in the sliding process, and prolong the service life of the connection member 33.

As shown in fig. 4, in some embodiments of the present invention, the first limiting portion 3121 is provided with a through hole, and an end of the connection member 33 is penetrated through the through hole and connected to the slider 32.

In some alternative embodiments of the invention, the connector 33 is a flexible member. It will be appreciated that the connector 33 is required to slidably engage the connector holder 12, and that during the sliding engagement, the connector 33 will deform, so that the connector 33 is configured as a flexible member to enhance the deformability of the connector 33 and increase the service life of the connector 33. The material of the flexible member may be synthetic fiber, natural fiber, ductile metal, etc., such as: nylon, steel wire, copper wire, etc., whereby the strength of the connection member 33 can be ensured, preventing the connection member 33 from being broken.

Referring to fig. 7, in some embodiments of the present invention, one end of the connection member 33 is connected to the slider 32, and the other end of the connection member 33 is connected to the limiting plate 22. When the slider 32 pulls the connecting piece 33 to move to the side far away from the connecting seat 12, the connecting piece 33 can apply a downward driving force to the connecting seat 12, at this time, the distance between the limiting plate 22 and the through hole 12a gradually decreases, and the cleaning part 10 moves downward relative to the driving assembly 20.

As shown in fig. 8 and 12, in some embodiments of the invention, the cleaning portion 10 further comprises a flange 13, the flange 13 being provided on the cleaning portion body 11, and the flange 13 extending from the edge of the cleaning portion body 11 to a side facing away from the cleaning face 10 a.

Referring to fig. 8 and 12, the flange 13 is disposed around the cleaning part body 11, and the flange 13 and the cleaning part body 11 together define an accommodating space for arranging the driving assembly 20 and the pressing assembly 30, and the flange 13 can play a good shielding role on the components disposed on the cleaning part body 11 to avoid the exposure of the components, and can also promote the appearance of the cleaning assembly 100.

In a further embodiment of the invention, the cleaning assembly further comprises: the first magnetic component (not shown in the figure) includes a first magnetic member disposed on a mating surface 32a of the slider 32 opposite to the flange 13, and a second magnetic member disposed on an inner wall surface 13a of the flange 13, and attractive force is provided between the first magnetic member and the second magnetic member.

Referring to fig. 8 and 12, when the cleaning assembly 100 is rotated rapidly, the slider 32 slides to the flange 13 side by centrifugal force, the first magnetic member and the second magnetic member are respectively disposed on the slider 32 and the flange 13, and when the slider 32 approaches to the flange 13 side, the attraction force between the first magnetic member and the second magnetic member is gradually increased; when the slider 32 moves to the side away from the flange 13, the attraction force between the first magnetic member and the second magnetic member gradually decreases.

It will be appreciated that the slider 32 moves towards the flange 13 under the action of centrifugal force, the magnitude of which is related to the mass of the slider 32, the radius of the circular motion of the slider 32 and the angular rotation speed, and in order to ensure the depressing effect of the cleaning portion 10 in the cleaning assembly 100, it is necessary to keep the cleaning portion 10 rotating at a high rotational speed so that the slider has sufficient centrifugal force at a corresponding position, and keeping the cleaning portion 10 rotating at a high rotational speed for a long time will result in a larger load of the driving assembly 20 and more energy (e.g. electric energy) is consumed.

Specifically, in the present application, as the slider 32 slides toward the flange 13 side, the attraction force between the first magnetic member and the second magnetic member gradually increases, and the attraction force is the same as the direction of the centrifugal force. Thus, when the slider 32 needs to be kept at the corresponding position, the cleaning portion 10 can be driven to rotate at a high speed to make the slider 32 approach to the flange 13 side, and then the rotation speed of the cleaning portion 10 is gradually reduced, at this time, the attraction force between the first magnetic member and the second magnetic member can be equivalent to a part of centrifugal force, so that the slider 32 can be kept at the corresponding position. That is, the cleaning portion 10 can ensure the pressing effect of the pressing assembly 30 even without maintaining a high rotation speed, and the cleaning portion 10 is driven to a preset cleaning height.

As shown in fig. 8 and 12, in some embodiments of the present invention, the shape of the mating surface 32a is adapted to the shape of the inner wall surface 13a of the flange 13, so that when the slider 32 abuts against the flange 13, the mating surface 32a is in fit with the inner wall surface 13a, so as to further ensure the adsorption mating effect of the first magnetic member and the second magnetic member. The "shape matching of the mating surface 32a and the flange 13" means that the mating surface 32a and the inner wall surface 13a have the same shape and size, when the slider 32 moves to the side of the flange 13, the slider can be abutted against the flange 13, at this time, the mating surface 32a is attached to the inner wall surface 13a, the first magnetic element and the second magnetic element are close in distance, and the magnetic attraction effect is good. Meanwhile, the contact area between the sliding block 32 and the flange 13 can be reasonably increased, damage caused by overlarge local stress of the flange 13 is avoided, and the reliability of the pressing process of the cleaning assembly 100 is improved.

Referring to fig. 8 and 12, in some embodiments of the present invention, the cleaning portion body 11 is configured in a disc shape, the flange 13 is disposed at an edge of the cleaning portion body 11 and is configured in a circular ring shape, at this time, an inner wall surface 13a of the flange 13 is configured in an arc surface, and accordingly, a surface (i.e., a mating surface 32 a) of the slider 32 disposed opposite to the inner wall surface 13a is configured in an arc surface, and an extending direction of the arc surface is the same as an extending direction of the flange 13, and extends in a circumferential direction of the cleaning portion body 11, so that a contact area when the slider 32 is in stop-fit with the flange 13 can be ensured, and a force applied to the flange 13 is uniform.

As shown in fig. 8, in some embodiments of the present invention, the mounting seat 31 includes a guide rail 311 and a limiting portion 312, one end of the guide rail 311 is connected to the inner wall surface 13a of the flange 13, the limiting portion 312 is disposed at the other end of the guide rail 311, and the flange 13 and the limiting portion 312 have a limiting effect on the sliding range of the slider 32, that is, the slider 32 can only slide between the flange 13 and the limiting portion 312.

In some embodiments of the invention, as shown in fig. 16, the cleaning assembly 100 further includes an upper cover 14 facing the cleaning portion 10 and covering the cleaning portion 10. The upper cover 14 can well shield the components (such as the driving component 20 and the pressing component 30), prevent the components from being exposed, and improve the reliability of the cleaning component 100.

As shown in fig. 5, in some embodiments of the present invention, the plurality of the pressing assemblies 30 are arranged at regular intervals on the outer side of the connection base 12 in the circumferential direction, so that the stability of driving the cleaning part 10 to move downward can be improved.

Referring to fig. 1, the through holes 12a and the slots on the connection base 12 are spaced apart in the circumferential direction of the rotation axis, so that interference between the connection member 33 and the insert rod and the slots can be prevented. Specifically, when the number of the insert pins and the slots is four and the number of the push-down assemblies 30 is also four, the through holes 12a and the slots are staggered one by one and arranged at intervals in the circumferential direction of the rotation axis.

In some embodiments of the present invention, the restoring member 40 is constructed as a spring, which has a simple structure and good elastic properties, and can secure the restoring effect of the cleaning portion 10. When the pressing assembly 30 drives the cleaning part 10 to move downward relative to the driving assembly 20, the spring is compressed or stretched to store energy, and when the driving force of the pressing assembly 30 is reduced, the spring can be reset to drive the cleaning part 10 to return to the initial position.

Referring to fig. 7, in a further embodiment of the present invention, the cleaning part 10 is provided with a first connection part 111, the driving assembly 20 is provided with a second connection part 212, the first connection part 111 is provided at a surface of the cleaning part body 11 facing away from the cleaning surface 10a, the second connection part 212 is provided at an outer circumferential surface of the driving seat 21, both ends of the reset element 40 are respectively connected with the first connection part 111 and the second connection part 212, and the second connection part 212 is higher in position than the second connection part 111 in the vertical direction. At this time, there is a height difference at both ends of the reset element 40, and when the cleaning part 10 moves downward with respect to the driving assembly 20, the reset element 40 can store energy sufficiently to apply the driving force of the upward movement to the cleaning part 10.

Further, the first connecting portion 111 is disposed on the outer side of the connecting seat 12 in the radial direction and is spaced from the connecting seat 12, and the resetting member 40 is disposed obliquely downward from the side of the driving seat 21. When the cleaning part 10 moves downward relative to the driving assembly 20, the reset element 40 is pulled in an oblique direction as a whole, and when the cleaning part 10 is reduced by the driving force of the pressing assembly 30, the reset element 40 contracts and drives the cleaning part 10 to move upward relative to the driving assembly 20.

In some embodiments of the present invention, the cleaning assembly 100 is provided with a plurality of resetting members 40, the plurality of resetting members 40 are spaced apart in the circumferential direction of the driving seat 21, and each resetting member 40 corresponds to a set of first connecting portions 111 and second connecting portions 212, so that the stress of the cleaning portion 10 is even, the driving effect of the resetting members 40 on the cleaning portion 10 can be ensured, and the stability of the upward movement process of the cleaning portion 10 is improved.

In some embodiments of the present invention, the first connection portion 111 is spaced apart from the pressing assembly 30 in the circumferential direction, so that the reset element 40 can be spaced apart from the pressing assembly 30, interference between the reset element 40 and the pressing assembly 30 is avoided, and reliability of the movement process of the cleaning assembly 100 is improved.

In some embodiments of the present invention, the first connection part 111 is configured as a first hook extending from the upper surface of the cleaning part body 11 toward the far side from the center to prevent the reset element 40 from being pulled out of the first hook; the second connection portion 212 is configured as a second hook extending upward from the outer wall of the driving seat 21 to prevent the reset element 40 from being removed from the second hook. Wherein, reset piece 40 is the spring, and the both ends of spring are provided with rings structure, and spring accessible rings structure and first couple and second couple are hung the cooperation.

Referring to fig. 8, 9 and 12, in some embodiments of the present invention, the first connection part 111 is disposed on a surface of the cleaning part body 11 facing away from the cleaning surface 10a, and the second connection part 212 is disposed on an outer circumferential surface of the driving seat 21, and the first connection part 111 is disposed adjacent to the second connection part 212 in a projection in a vertical direction.

When the cleaning part 10 moves downward with respect to the driving assembly 20, the second connection part 212 moves downward with respect to the first connection part 111 in the vertical direction. Since the first connection portion 111 and the second connection portion 212 are adjacently disposed on the projection in the vertical direction, the reset member 40 deforms and applies a vertically upward force to the first connection portion 111. It will be appreciated that the resetting member 40 applies a force to the first connecting portion 111 in a vertical direction, which is the same as the direction of movement of the cleaning portion 10 relative to the driving assembly 20, so that stability of the cleaning portion 10 during resetting can be improved.

As shown in fig. 11, in some embodiments of the present invention, the restoring member 40 is configured as a coil spring 41, a pull-out end 412 of the coil spring 41 is fixedly coupled to the second coupling part 212, a winding body 411 of the coil spring 41 is rotatably installed to the first coupling part 111, and the coil spring 41 can be pulled out in a vertical direction, so that stability and reliability of the up-and-down movement of the cleaning part 10 with respect to the driving assembly 30 can be further improved.

Specifically, referring to fig. 11, when the cleaning portion 10 moves downward with respect to the driving assembly 30, the pull-out end 412 of the coil spring 41 is pulled out in the vertical direction, the return driving force applied to the first connection portion 111 by the coil spring 41 is constant during the pulling-out of the coil spring 41, and the return driving force applied to the coil spring 41 is constant, that is, the return driving force applied to the connection base 12 by the coil spring 41 is maintained substantially constant when the cleaning portion 10 is driven to be depressed, without being affected by the depressing distance of the cleaning portion 10. Since the reset driving force of the coil spring 41 can be kept constant, the cleaning part 10 can be driven to be pressed down when the downward driving force of the pressing component 30 applied to the cleaning part 10 is larger than the reset driving force, at this time, the reset driving force applied by the reset piece 40 can not be changed obviously along with the pressing distance of the cleaning part 10, the driving difficulty in the pressing process of the cleaning part 10 can be reduced, and the pressing effect of the cleaning part 10 is ensured.

Further, when the cleaning portion 10 needs to be reset, the cleaning portion 10 is in a pressed state, the rotation speed of the driving assembly 20 for driving the cleaning portion 10 needs to be reduced, so as to reduce the pressing driving force applied to the cleaning portion 10 by the pressing assembly 30, and at this time, the cleaning portion 10 can be moved upward and reset relative to the driving assembly 20 under the action of the constant reset driving force applied by the coil spring 41. Among them, since the reset driving force applied by the coil spring 41 tends to be constant, the stability during reset of the cleaning portion 10 is good. When the driving assembly 20 stops driving the cleaning part 10 to rotate, the cleaning part 10 is only subjected to gravity and the reset driving force of the coil spring 41, and at this time, the cleaning part 10 can be maintained to be reset upward at a constant speed.

As shown in fig. 9, in some embodiments of the present invention, the first connection portion 111 is formed with a mounting groove 111a, the pull-out end 412 of the coil spring 41 is fixedly connected with the second connection portion 212, the winding body 411 is embedded in the mounting groove 111a, and the winding body is rotatably mounted in the mounting groove 111a by the mounting shaft 112, the pull-out end 412 of the coil spring 41 extends in the vertical direction, and the connection manner of the coil spring 41 is simple and highly reliable.

In some embodiments of the present invention, the cleaning assembly 100 further comprises: the second magnetic component comprises a third magnetic piece 51 and a fourth magnetic piece 52, the third magnetic piece 51 is arranged on the driving component 30, the fourth magnetic piece 52 is arranged on the cleaning part 10, the third magnetic piece 51 is opposite to the fourth magnetic piece 52 and is arranged at intervals, and attractive force in the vertical direction is formed between the third magnetic piece 51 and the fourth magnetic piece 52.

It will be appreciated that when the cleaning part 10 is located at the initial position (i.e., at the position when not depressed), the distance between the third magnetic member 51 and the fourth magnetic member 52 is closest, the magnetic attraction between the third magnetic member 51 and the fourth magnetic member 52 is maximum, and when the cleaning part 10 moves downward, the magnetic attraction between the third magnetic member 51 and the fourth magnetic member 52 gradually decreases as the cleaning part 10 is driven to be depressed, so that the depressing effect of the cleaning part 10 can be ensured. Wherein the magnetic attraction between the third magnetic member 51 and the fourth magnetic member 52 also has a reset effect.

Further, as the cleaning part 10 moves downward during the downward movement of the cleaning part 10 driven by the pressing down assembly 30, the third magnetic member 51 and the fourth magnetic member 52 gradually decrease. Since the cleaning part 10 is rotated by driving the present application to generate a downward driving force by the pressing assembly 30, the magnitude of the pressing driving force is related to the rotation speed of the cleaning part 10. After the cleaning part 10 is driven to be pressed down, the rotation speed of the cleaning part 10 can be reasonably reduced, and the cleaning part 10 can be kept at the corresponding pressing-down position at the moment, so that the energy consumption of the cleaning assembly can be reduced while the cleaning effect of the cleaning part 10 is ensured.

When the cleaning part 10 needs to be reset, the cleaning part 10 is in a pressing state, the rotation speed of the driving assembly 20 for driving the cleaning part needs to be reduced, so that the pressing driving force applied to the cleaning part 10 by the pressing assembly 30 is reduced, and at this time, the cleaning part 10 can be driven to move upwards relative to the driving assembly 20 to reset under the action of magnetic attraction force between the third magnetic piece 51 and the fourth magnetic piece 52. Wherein, since the magnitude of the magnetic attraction force between the third magnetic member 51 and the fourth magnetic member 52 is related to the distance therebetween, the magnetic attraction force between the third magnetic member 51 and the fourth magnetic member 52 is gradually increased along with the upward movement of the cleaning portion 10 for resetting, so that the resetting effect of the cleaning portion 10 can be ensured. When the driving assembly 20 stops driving the cleaning part to rotate, the cleaning part 10 is only subjected to gravity and the reset driving force of the second magnetic attraction assembly (the magnetic attraction force between the third magnetic element 51 and the fourth magnetic element 52), the cleaning part 10 slowly rises at the initial stage in the reset process, and the reset speed gradually increases along with the rising of the cleaning part 10, so that the reset action of quickly resetting the cleaning part 10 after slowly rising is realized, and the reset effect of the cleaning part is ensured.

In a further embodiment of the invention, the third magnetic member 51 is arranged on the driving seat, the fourth magnetic member 52 is arranged on the connecting seat, and the third magnetic member 51 and the fourth magnetic member 52 are arranged opposite to each other in the vertical direction. Wherein at least one of the third magnetic member 51 and the fourth magnetic member 52 is configured as a magnet, and the other of the third magnetic member 51 and the fourth magnetic member 52 is configured as a magnetic member such as a magnet or an iron block, so as to ensure that a magnetic attraction exists between the third magnetic member 51 and the fourth magnetic member 52. If the third magnetic element 51 and the fourth magnetic element 52 are each configured as a magnet, two opposite poles of the third magnetic element 51 and the fourth magnetic element 52 are disposed opposite each other.

The cleaning assembly 100 of the present application is applicable to a first type of cleaning robot for cleaning a floor, such as a sweeping robot, etc. When the cleaning assembly 100 performs a cleaning operation, the cleaning surface 10a is attached to the floor surface, so as to ensure the cleaning effect on the floor surface. If there is an obstacle on the floor, when the first cleaning robot moves to the obstacle, the side wall of the cleaning part 10 may be in contact with the obstacle, and at this time, the cleaning part 10 may be lifted (i.e., move upward relative to the driving assembly 20), so as to avoid the obstacle, so as to improve the obstacle surmounting capability of the first cleaning robot.

It will be appreciated that when the side wall of the cleaning part 10 contacts an obstacle, the obstacle acts as an obstacle to the rotation of the cleaning part 10, which results in a reduction in the rotational angular velocity of the cleaning part 10, and the centrifugal force of the slider 32 is reduced, which in turn reduces the driving force of the pressing assembly 30 on the cleaning part 10, and at this time the cleaning part 10 can move upward relative to the driving assembly 20 under the action of the reset member 40 to be spaced apart from the ground, so that the first cleaning robot can pass over the obstacle.

The operation of the cleaning assembly 100 according to an embodiment of the present invention is described with reference to fig. 1-6:

referring to fig. 1, the cleaning assembly 100 is in an initial state in which the driving assembly 20 does not drive the cleaning part 10 to rotate and the pressing assembly 30 does not apply a driving force to the cleaning part 10. The slider 32 is in abutting engagement with the first stopper 3121 by the reset means 40.

When the driving component 20 drives the cleaning part 10 to rotate, the pressing component 30 rotates synchronously with the driving component, the sliding block 32 slides along the direction of the guide rail 311 to a side far away from the connecting seat 12 under the action of centrifugal force, at this time, the connecting piece 33 applies a downward driving force to the connecting seat 12, the cleaning part 10 moves downward relative to the driving component 20 to adjust the distance between the cleaning surface 10a and the ground, and the resetting piece 40 stores energy in the downward movement process of the cleaning part 10 relative to the driving component 20.

When the rotational speed of the driving unit 20 driving the cleaning unit 10 decreases, the driving force applied to the connection base 12 by the pressing unit 30 decreases, and if the downward driving force is smaller than the driving force of the reset element 40, the cleaning unit 10 moves upward relative to the driving unit 20 under the action of the reset element 40, and the connection base 12 applies the driving force to the connection element 33 to pull the slider 32 to slide toward the side close to the connection base 12. When the driving assembly 20 no longer drives the cleaning part 10 to rotate, the resetting member 40 can reset the cleaning part 10 to the initial position.

According to the first cleaning robot of the embodiment of the present invention, the first cleaning robot includes the above-mentioned cleaning assembly 100, and the pressing assembly 30 applies a driving force for downward movement to the cleaning part 10 during rotation of the cleaning part 10 to press the cleaning part 10 downward, so that the cleaning surface 10a is closely attached to the ground, the cleaning effect of the cleaning part 10 on the ground is improved, and the cleaning part 10 can be lifted or reset when encountering an obstacle or non-working, so that the cleaning surface 10a is spaced apart from the ground, and the obstacle surmounting capability of the first cleaning robot is improved.

In some embodiments of the present invention, the first cleaning robot is provided with a plurality of cleaning assemblies 100, and the plurality of cleaning assemblies 100 are arranged at intervals in the width direction of the first cleaning robot body, so that the cleaning area of the first cleaning robot can be increased, and the cleaning efficiency can be improved.

Since the cleaning assembly 100 has a function of driving the cleaning part 10 to move downward so that the cleaning surface 10a is attached to the floor, when the amount of water in the water tank is reduced, the cooperation effect of the cleaning surface 10a and the floor can be ensured, thereby ensuring the cleaning effect of the first cleaning robot on the floor.

It should be noted that, the existing robot is provided with a water tank, and uses its own weight to make its cleaning portion attach to the ground, however, as the cleaning solution in the water tank gradually flows out and decreases, the pressure of the cleaning portion on the ground gradually decreases, and the cleaning portion cannot be guaranteed to be fully contacted with the ground, so as to affect the cleaning effect of the robot on the ground.

The first type cleaning robot in this application is provided with clean subassembly 100, and clean subassembly 100 can be when rotating clean portion 10 clear up ground to clean portion 10 push down through pushing down subassembly 30, with clean face 10a and ground laminating, guarantees clean portion 10 to the cleaning effect on ground, and the influence is less by the change of first type cleaning robot 100 self weight.

The cleaning assembly 100 of the present application is also applicable to a second type of cleaning robot where the cleaning surface is a non-horizontal surface, such as a window glass surface, as compared to the first type of cleaning robot where the cleaning surface is a floor surface, where the second type of cleaning robot may be a window cleaning machine. When the cleaning assembly 100 performs a cleaning action, the self weight of the cleaning portion 10 and the water tank disposed on the cleaning portion 10 cannot be converted into the friction force between the cleaning surface 10a and the cleaning surface, and at this time, when the cleaning portion 10 is driven to rotate by the driving assembly 20, the pressing assembly 30 rotates synchronously with the driving portion, and under the action of centrifugal force, the cleaning surface 10a contacts with the cleaning surface and converts the force into the friction force, so as to ensure the cleaning effect on the cleaning surface.

In a further embodiment of the present invention, the second cleaning robot further includes: the second cleaning robot can still keep working state when the adsorption device (not shown) ensures that the cleaning surface is non-horizontal, so as to realize cleaning of the cleaning surface.
