Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

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

The cleaning assembly 100 according to an embodiment of the present invention includes: cleaning portion 10, drive assembly 20, hold-down assembly 30, and restoring member 40.

Wherein, the cleaning part 10 is rotatably arranged at the bottom of the cleaning robot, the cleaning part 10 is provided with a cleaning surface 10a, the cleaning surface 10a is used for cleaning the cleaning surface, and the cleaning surface can be the ground, the wall surface, the glass surface of the window, etc. The cleaning assembly 100 of the present application will now be described with reference to an example in which the cleaning surface is a floor surface.

The cleaning part 10 cleans the cleaning surface in a rotating mode, 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 mode, so that the cleaning effect is good.

As shown in fig. 1 and 4, a 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 perform a cleaning action of the cleaning part 10.

As shown in fig. 1 and 4, the pressing assemblies 30 are respectively connected to the cleaning portion 10 and the driving assembly 20, and the pressing assemblies 30 can apply a driving force to the cleaning portion 10 when the cleaning portion 10 rotates, so as to drive the cleaning portion 10 to slide downwards relative to the driving assembly 20, so as to attach the cleaning portion 10 to the cleaning surface, and ensure the cleaning effect of the cleaning portion 10.

The cleaning surface comprises a ground, a wall surface, a ceiling, a window glass surface and the like, wherein 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 in the present application can be applied to a window cleaner or a sweeping robot.

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

As shown in fig. 7, the restoring member 40 is connected between the driving assembly 20 and the cleaning part 10, and the restoring member 40 can accumulate energy when the pressing assembly 30 drives the cleaning part 10 to move downward (toward the cleaning surface side) relative to the driving assembly 20 and apply a driving force (restoring driving force) to the cleaning part 10 to move upward relative to the driving assembly 20.

Specifically, the reset member 40 is connected between the driving assembly 20 and the cleaning part 10, when the cleaning part 10 is not rotated, the pressing assembly 30 does not apply a driving force to the cleaning part 10, and the cleaning part 10 can be fixed at an initial position by the reset member 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 by the driving force while the restoring member 40 accumulates energy to drive the cleaning part 10 to move to the initial position in a state that the driving force is reduced or eliminated.

It should be noted that the "initial position" refers to a position of the cleaning part 10 with respect to the driving assembly 20 in a state where the cleaning assembly 100 is not operated.

It can be understood 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 walking resistance of the cleaning robot can be reduced, the movement of the cleaning robot is facilitated, and a gap can be reserved between the cleaning assembly 100 and the cleaning surface, thereby improving the obstacle crossing ability of the cleaning robot. When the cleaning part 10 is required to clean a cleaning surface, the driving assembly 20 is controlled to drive the cleaning part 10 to rotate, the pressing assembly 30 can apply a driving force to the cleaning part 10 while the cleaning part 10 rotates to drive the cleaning part 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 part 10 on the cleaning surface is ensured, and in the process that the cleaning part 10 moves downwards relative to the driving assembly 20, the resetting member 40 stores energy until the position of the cleaning part 10 relative to the driving assembly 20 does not change any more. At this time, if the downward pressing driving force applied to the cleaning part 10 by the pressing assembly 30 is reduced, the restoring member 40 may drive the cleaning part 10 to move upward relative to the driving assembly 20, that is, the cleaning part 10 moves to a side far away from the floor, so as to space the cleaning surface 10a from the floor, thereby facilitating the cleaning part 10 to cross an obstacle on the floor, and improving the obstacle crossing ability of the cleaning assembly 100.

Wherein, the pushing down action of the pushing down assembly 30 is performed simultaneously with the driving assembly 20 driving the cleaning part 10 to rotate, when the cleaning part 10 is blocked during the rotation process, which results in the reduction of the rotation speed of the cleaning part 10 or the stagnation, the pushing down assembly 30 no longer applies a downward driving force to the cleaning part 10, and the cleaning part 10 can be quickly reset (i.e. moved upwards) under the action of the resetting member 40.

It should be further noted that the cleaning robot is provided with a vision sensor, and the vision sensor is used for detecting an obstacle on a traveling path of the cleaning robot, so that the cleaning robot can avoid the obstacle. When the cleaning robot judges that the cleaning part 10 can be lifted over an obstacle, the rotation speed of the driving component 20 for driving the cleaning part 10 can be reduced to lift the cleaning part 10, so that the cleaning robot can conveniently pass over the obstacle, and the cleaning part can smoothly pass over the obstacle; when the cleaning robot judges that the cleaning robot cannot pass over the obstacle (cannot pass over the obstacle 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 conveniently. The visual sensor can realize the functions of active obstacle crossing and active obstacle avoidance, but the visual sensor still cannot detect the obstacle due to the fact that the obstacle is low and the like.

When the cleaning part 10 cleans the floor, the cleaning part 10 is closely attached to the floor to ensure the cleaning effect. When the cleaning part 10 contacts with an obstacle on the ground in the traveling process of the cleaning robot, the rotation of the cleaning part 10 is blocked, at the moment, the cleaning part 10 stops rotating or the rotating speed is greatly reduced, the cleaning part 10 can be quickly reset under the action of the resetting piece 40, namely, the cleaning part 10 is quickly lifted upwards to avoid the obstacle, and the cleaning robot can cross over the obstacle. The cleaning part 10 stops rotating or the rotating speed is greatly reduced by the way that the cleaning part 10 or the cleaning surface 10a touches an 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 housing, the position of the driving assembly 20 relative to the housing does not change, and since the pressing assembly 30 is respectively connected with the cleaning part 10 and the driving assembly 20, when the pressing assembly 30 applies a driving force to the cleaning part 10 to move towards the cleaning surface side relative to the driving assembly 20, the cleaning part 10 moves synchronously relative to the housing while moving relative to the driving assembly 20, so that the position of the cleaning part 10 relative to the housing can be adjusted.

According to the cleaning assembly 100 of the embodiment of the invention, the driving assembly 20 can drive the cleaning part 10 to rotate, and simultaneously the pressing assembly 30 can drive the cleaning part 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 surface 10a on the cleaning surface is ensured, and the cleaning surface 10a cleans the cleaning surface by applying pressure to the cleaning surface and rotating, and the cleaning effect of the cleaning assembly 100 on the cleaning surface can be further improved. When the traveling direction of the cleaning assembly 100 encounters an obstacle, the restoring member 40 drives the cleaning portion 10 to move upward, i.e., separates the cleaning surface 10a from the cleaning surface, so that the cleaning assembly 100 can pass through the obstacle, and the obstacle crossing ability of the cleaning assembly 100 is improved.

As shown in fig. 4, in some embodiments of the present invention, the cleaning part 10 includes: cleaning portion body 11 and connecting seat 12, cleaning portion body 11 is provided with cleaning surface 10a, and connecting seat 12 sets up on cleaning portion body 11, and connecting seat 12 is located the central point on the surface that cleaning portion body 11 deviates from cleaning surface 10a one side moreover, and connecting seat 12 links to each other with drive assembly 20.

It should be noted that the "central position" of the cleaning section body 11 is related to the shape of the cleaning section body 11, and when the cleaning section body 11 is configured as a circle, the central position is the position of the center of the circle; when the cleaning part body 11 is configured as a regular polygon, the central position is the center of the regular polygon. Preferably, the cleaning part body 11 is constructed in a regular pattern of a circular, regular polygonal structure, thereby facilitating the determination of the position of the coupling holder 12 and ensuring the stability during the rotation of the cleaning part 10.

The slider 32 is slidable along the extending direction of the guide rail 311, and the stopper 312 is provided to limit the slider 32.

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 slide further relative to the guide 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 sliding block 32 and the connecting seat 12, and the second limiting portion 3122 is disposed on a side of the sliding block 32 departing from the connecting seat 12.

In some embodiments of the present invention, the driving manner of the slider 32 may include a driving device and a centrifugal force driving, the driving device is connected to the slider 32 and is used to drive the slider 32 to slide, so as to pull the connecting member 33 through the slider 32, thereby achieving the adjustment of the position of the cleaning part 10; when the cleaning part 10 is driven to rotate by centrifugal force, the sliding block 32 has a moving tendency to move to the side far away from the connecting seat 12, that is, the sliding block 32 can do centrifugal motion.

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

Wherein the centrifugal force is related to the mass of the slider 32, the rotational angular speed of the cleaning part 10, and the distance between the slider 32 and the rotational axis. During the rotation of the cleaning part 10, when the rotation angular speed 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 centrifugal force, and 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 can also be adjusted by adjusting the angular speed of rotation 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 connecting socket 12 is provided with a through hole 12a, and the other end of the connecting member 33 passes through the through hole 12a and is connected to the driving assembly 20. The two ends of the connecting member 33 are respectively connected to the driving assembly 20 and the sliding block 32, and when the sliding block 32 slides to the side away from the connecting seat 12, the sliding block 32 pulls the connecting member 33, and at this time, the connecting member 33 can apply a 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-shaped surface is formed in the circumferential direction of the via hole 12a, and the connecting member 33 abuts against the arc-shaped surface, so that the arc-shaped surface can reduce the sliding resistance between the connecting member 33 and the connecting seat 12, prevent the connecting member 33 from being damaged during the sliding process, and prolong the service life of the connecting member 33.

As shown in fig. 4, in some embodiments of the present invention, the first position-limiting portion 3121 is provided with a through hole, and the end of the connecting member 33 is inserted through the through hole and connected to the sliding block 32.

In some alternative embodiments of the present invention, the connecting member 33 is a flexible member. It can be understood that the connecting member 33 needs to be in sliding fit with the connecting seat 12, and during the sliding fit, the connecting member 33 will deform, so that configuring the connecting member 33 as a flexible member can improve the deformability of the connecting member 33 and prolong the service life of the connecting member 33. Wherein, the material of the flexible member can be synthetic fiber, natural fiber, metal with ductility, etc., such as: nylon, steel wire and copper wire etc. can guarantee the intensity of connecting piece 33 from this, prevents that connecting piece 33 from splitting.

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 stopper plate 22. When the slider 32 pulls the connecting member 33 to move away from the connecting seat 12, the connecting member 33 can apply a downward driving force to the connecting seat 12, and 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 present invention, the cleaning portion 10 further includes a burring 13, the burring 13 is provided on the cleaning portion body 11, and the burring 13 extends from an edge of the cleaning portion body 11 toward a side away from the cleaning surface 10 a.

Referring to fig. 8 and 12, the turned-up edge 13 is disposed around the cleaning portion body 11, and the turned-up edge 13 and the cleaning portion body 11 together define an accommodating space for arranging the driving assembly 20 and the pressing assembly 30, and the turned-up edge 13 can perform a good shielding function on components disposed on the cleaning portion body 11 to prevent the components from being exposed, and can also enhance 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) comprises a first magnetic part and a second magnetic part, the first magnetic part is arranged on a matching surface 32a of the sliding block 32, which is opposite to the flange 13, the second magnetic part is arranged on the inner wall surface 13a of the flange 13, and attraction force exists between the first magnetic part and the second magnetic part.

Referring to fig. 8 and 12, when the cleaning assembly 100 is rotated rapidly, the slider 32 slides to the side of the flange 13 under the action of 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 side of the flange 13, the attractive force between the first magnetic member and the second magnetic member is gradually increased; when the slide block 32 moves to the side far away from the flange 13, the attraction force between the first magnetic part and the second magnetic part is gradually reduced.

It can be understood that the slide block 32 moves towards the side of the flange 13 under the action of centrifugal force, the magnitude of the centrifugal force is related to the mass of the slide block 32, the radius of the circular motion of the slide block 32 and the rotation angular velocity, in order to ensure the pressing-down effect of the cleaning part 10 in the cleaning assembly 100, it is necessary to keep the rotation speed of the cleaning part 10 high so that the slide block has sufficient centrifugal force at the corresponding position, and keeping the rotation speed of the cleaning part 10 high for a long time will cause the load of the driving assembly 20 to be large and consume more energy (such as electric energy).

Specifically, in the present application, as the slider 32 slides toward the flange 13, the attraction force between the first magnetic member and the second magnetic member gradually increases, and the direction of the attraction force is the same as the direction of the centrifugal force. Therefore, when the slide block 32 needs to be kept at the corresponding position, the cleaning part 10 can be driven to rotate at a high speed to enable the slide block 32 to approach to the flanging 13 side, and then the rotating speed of the cleaning part 10 is gradually reduced, at this time, the adsorption force between the first magnetic member and the second magnetic member can be equivalent to a part of centrifugal force, so that the slide block 32 can be kept at the corresponding position. That is, the cleaning part 10 can secure the pressing effect of the pressing assembly 30 even without maintaining a high rotation speed, driving the cleaning part 10 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 fits snugly with the inner wall surface 13a, so as to further ensure the attraction-fit effect of the first magnetic member and the second magnetic member. The term "the mating surface 32a is adapted to the shape of the flange 13" means that the mating surface 32a is the same as the inner wall surface 13a in shape and size, and when the slider 32 moves to the flange 13 side, it can abut against the flange 13, and at this time, the mating surface 32a is attached to the inner wall surface 13a, and the first magnetic member and the second magnetic member are close to each other and have a good magnetic attraction effect. Meanwhile, the contact area between the sliding block 32 and the flanging 13 can be reasonably increased, the damage of the flanging 13 due to overlarge local stress 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 to be a disk, the flange 13 is disposed at the edge of the cleaning portion body 11 and configured to be a circular ring, at this time, the inner wall surface 13a of the flange 13 is an arc surface, and correspondingly, the surface of the slider 32 opposite to the inner wall surface 13a (i.e., the mating surface 32a) is configured to be an arc surface, and the extending direction of the arc surface is the same as the extending direction of the flange 13 and both extend along the circumferential direction of the cleaning portion body 11, so that the contact area when the slider 32 and the flange 13 are in abutting engagement can be ensured, and the stress at 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.

As shown in fig. 16, in some embodiments of the present invention, the cleaning assembly 100 further includes an upper cover 14 facing the cleaning part 10 and covering the cleaning part 10. The upper cover 14 can shield the components (e.g., the driving assembly 20 and the pressing assembly 30) well, so as to prevent the components from being exposed and improve the reliability of the cleaning assembly 100.

As shown in fig. 5, in some embodiments of the present invention, the pressing assemblies 30 are plural, and the plural pressing assemblies 30 are uniformly spaced outside of the connecting seat 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 of the connector holder 12 are spaced in the circumferential direction of the rotation axis, and interference between the connectors 33 and the insertion rods and the slots can be prevented. Specifically, when the number of the insert rods and the slots is four and the number of the hold-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 configured as a spring, which has a simple structure and good elastic performance, and can ensure the restoring effect of the cleaning part 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 extended to accumulate 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 portion 10 is provided with a first connecting portion 111, the driving assembly 20 is provided with a second connecting portion 212, the first connecting portion 111 is provided on a surface of the cleaning portion body 11 on a side away from the cleaning surface 10a, the second connecting portion 212 is provided on an outer circumferential surface of the driving seat 21, two ends of the restoring member 40 are respectively connected to the first connecting portion 111 and the second connecting portion 212, and a position of the second connecting portion 212 in the vertical direction is higher than that of the second connecting portion 111. At this time, there is a height difference between both ends of the restoring member 40, and when the cleaning part 10 moves downward relative to the driving assembly 20, the restoring member 40 can sufficiently accumulate energy to apply a driving force of the upward movement to the cleaning part 10.

Further, first coupling portion 111 is provided at the outer side of coupling holder 12 in the radial direction and is spaced apart from coupling holder 12, and restoring member 40 is inclined downward from the side of driving holder 21. When the cleaning part 10 moves downward relative to the driving assembly 20, the restoring member 40 is stretched 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 restoring member 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 restoring members 40, the plurality of restoring members 40 are arranged at intervals in the circumferential direction of the driving seat 21, and each restoring member 40 corresponds to one set of the first connecting portion 111 and the second connecting portion 212, so that the cleaning portion 10 is stressed evenly, the driving effect of the restoring members 40 on the cleaning portion 10 can be ensured, and the stability of the upward movement process of the cleaning portion 10 can be improved.

In some embodiments of the present invention, the first connecting portion 111 is spaced from the lower pressing assembly 30 in the circumferential direction, so that the restoring member 40 can be spaced from the lower pressing assembly 30, interference between the restoring member 40 and the lower 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 coupling portion 111 is configured as a first hook extending from the upper surface of the body 11 toward the side away from the center to prevent the restoring member 40 from coming off the first hook; second coupling portion 212 is configured as a second hook extending upward from the outer wall surface of driving seat 21 to prevent restoring member 40 from being released from the second hook. Wherein, the piece that resets 40 is the spring, and the both ends of spring are provided with rings structure, and spring accessible rings structure articulates the cooperation with first couple and second couple.

With reference to fig. 8, 9 and 12, in some embodiments of the present invention, the first connecting portion 111 is disposed on a surface of the cleaning portion body 11 on a side away from the cleaning surface 10a, the second connecting portion 212 is disposed on an outer circumferential surface of the driving seat 21, and the first connecting portion 111 and the second connecting portion 212 are disposed adjacent to each other in a vertical projection.

When the cleaning part 10 moves downward with respect to the driving assembly 20, the second connecting part 212 moves downward with respect to the first connecting part 111 in the vertical direction. Since the first connecting portion 111 and the second connecting portion 212 are adjacently disposed in the projection of the vertical direction, the restoring member 40 deforms and applies a vertically upward force to the first connecting portion 111. It can be understood that the restoring member 40 applies a force in a vertical direction to the first connecting portion 111, the force in the vertical direction being the same as the movement direction of the cleaning portion 10 with respect to the driving assembly 20, so that the stability of the cleaning portion 10 during the restoring process 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 pulling end 412 of the coil spring 41 is fixedly connected to the second connecting portion 212, a winding body 411 of the coil spring 41 is rotatably mounted to the first connecting portion 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 relative to the driving assembly 30 can be further improved.

Specifically, referring to fig. 11, when the cleaning section 10 moves downward relative to the driving assembly 30, the pulling end 412 of the coil spring 41 is pulled out in the vertical direction, the return driving force applied by the coil spring 41 to the first connecting section 111 in the process of pulling out the coil spring 41 is constant, and the return driving force applied by the coil spring 41 is constant, that is, when the cleaning section 10 is driven by being pressed downward, the return driving force applied by the coil spring 41 to the connecting section 12 is kept substantially constant regardless of the pressing distance of the cleaning section 10. Because the reset driving force of the coil spring 41 can be kept constant, the cleaning part 10 can be driven to press down when the driving force of the downward movement applied to the cleaning part 10 by the pressing assembly 30 is greater than the reset driving force, at this time, the reset driving force applied by the reset member 40 does not change significantly 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 part 10 needs to be reset, the cleaning part 10 is in a pressing-down state, and the rotation speed of the driving assembly 20 for driving the cleaning part 10 needs to be reduced to reduce the pressing-down driving force applied to the cleaning part 10 by the pressing-down assembly 30, at this time, the cleaning part 10 can be reset by moving upward relative to the driving assembly 20 under the constant resetting driving force applied by the coil spring 41. Among them, since the return driving force applied by the coil spring 41 tends to be constant, the stability in the return process 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 driven by gravity and the return driving force of the coil spring 41, and the cleaning part 10 can be returned upward at a constant speed.

As shown in fig. 9, in some embodiments of the present invention, the first connecting portion 111 is formed with a mounting groove 111a, the drawing end 412 of the coil spring 41 is fixedly connected with the second connecting portion 212, the winding body 411 is embedded in the mounting groove 111a, and is rotatably mounted in the mounting groove 111a by the mounting shaft 112, the drawing 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 attraction 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 and the fourth magnetic piece 52 are arranged right opposite and at intervals, and attraction force in the vertical direction is formed between the third magnetic piece 51 and the fourth magnetic piece 52.

It is understood that when the cleaning part 10 is located at the initial position (i.e., at the position when not pressed down), the distance between the third magnetic member 51 and the fourth magnetic member 52 is the closest, the magnetic attraction force between the third magnetic member 51 and the fourth magnetic member 52 is the largest, and when the cleaning part 10 moves downward, as the cleaning part 10 is driven to be pressed down, the magnetic attraction force between the third magnetic member 51 and the fourth magnetic member 52 is gradually reduced, so that the pressing-down 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, during the downward movement of the cleaning part 10 driven by the pressing assembly 30, the distance between the third magnetic member 51 and the fourth magnetic member 52 gradually decreases as the cleaning part 10 moves downward. Since the present application is driven by the cleaning part 10 to rotate so as to generate the 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 rotating speed of the cleaning part 10 can be reasonably reduced, and the cleaning part 10 can be kept at the corresponding pressing position, 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 pressed-down state, the rotation speed of the driving component 20 for driving the cleaning part needs to be reduced to reduce the pressing-down driving force applied to the cleaning part 10 by the pressing-down component 30, and at this time, under the action of the magnetic attraction force between the third magnetic member 51 and the fourth magnetic member 52, the cleaning part 10 can be driven to move upwards and reset relative to the driving component 20. Since the magnetic attraction between the third magnetic member 51 and the fourth magnetic member 52 is related to the distance therebetween, the magnetic attraction between the third magnetic member 51 and the fourth magnetic member 52 is gradually increased along with the upward movement and resetting of the cleaning unit 10, so that the resetting effect of the cleaning unit 10 can be ensured. When the driving assembly 20 stops driving the cleaning portion to rotate, the cleaning portion 10 is only driven by gravity and the reset driving force of the second magnetic attraction assembly (the magnetic attraction force between the third magnetic member 51 and the fourth magnetic member 52), the cleaning portion 10 slowly ascends at the initial stage in the reset process, and the reset speed gradually increases along with the ascending of the cleaning portion 10, so that the reset action of quick reset after the cleaning portion 10 slowly ascends is realized, and the reset effect of the cleaning portion is ensured.

In a further embodiment of the present invention, the third magnetic member 51 is disposed on the driving seat, the fourth magnetic member 52 is disposed on the connecting seat, and the third magnetic member 51 and the fourth magnetic member 52 are disposed opposite to each other in the vertical direction. 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 force exists between the third magnetic member 51 and the fourth magnetic member 52. If the third magnetic member 51 and the fourth magnetic member 52 are both configured as magnets, two opposite magnetic poles of the third magnetic member 51 and the fourth magnetic member 52 are disposed opposite to each other.

The cleaning assembly 100 in the present application can be applied to a first cleaning robot for cleaning the ground, such as a sweeping robot. When the cleaning assembly 100 performs a cleaning action, the cleaning surface 10a is attached to the floor surface to ensure a 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 can contact with the obstacle, and at this time, the cleaning part 10 can be lifted (i.e. moved upward relative to the driving assembly 20) to avoid the obstacle, so as to improve the obstacle crossing ability of the first cleaning robot.

It can be understood that when the side wall of the cleaning part 10 contacts with an obstacle, the obstacle acts as an obstacle to the rotation of the cleaning part 10, which will result in the reduction of the rotation angular speed of the cleaning part 10, the centrifugal force of the slider 32 is reduced, and the driving force of the pressing assembly 30 to the cleaning part 10 is reduced, and at this time, the cleaning part 10 can move upward relative to the driving assembly 20 under the action of the restoring member 40 to be spaced apart from the ground, so that the first cleaning robot can conveniently 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. Under the action of the restoring member 40, the sliding block 32 is in abutting engagement with the first limit portion 3121.

When the driving assembly 20 drives the cleaning part 10 to rotate, the pressing assembly 30 rotates synchronously with the driving part, the slider 32 slides to a side away from the connecting seat 12 along the direction of the guide rail 311 under the action of centrifugal force, the connecting member 33 applies a driving force to the connecting seat 12 to move downwards, the cleaning part 10 moves downwards relative to the driving assembly 20 to adjust the distance between the cleaning surface 10a and the ground, and the restoring member 40 accumulates energy during the downward movement of the cleaning part 10 relative to the driving assembly 20.

When the driving assembly 20 drives the cleaning part 10 to rotate at a reduced speed, the driving force applied by the pressing assembly 30 to the connecting seat 12 is reduced, and if the downward driving force is smaller than the driving force of the resetting member 40, the cleaning part 10 will move upward relative to the driving assembly 20 under the action of the resetting member 40, and the connecting seat 12 applies a driving force to the connecting member 33 to pull the slider 32 to slide to a side close to the connecting seat 12. When the driving assembly 20 no longer drives the cleaning part 10 to rotate, the restoring member 40 may restore the cleaning part 10 to the initial position.

According to the first cleaning robot of the embodiment of the invention, the first cleaning robot comprises the cleaning assembly 100, during the rotation of the cleaning part 10, the pressing assembly 30 applies a driving force of downward movement to the cleaning part 10 to press the cleaning part 10 downwards, so that the cleaning surface 10a is tightly 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 meeting an obstacle or not working, so that the cleaning surface 10a is separated from the ground, and the obstacle crossing 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 main body, so that the cleaning area of the first cleaning robot can be increased, and the cleaning efficiency can be improved.

In a further embodiment of the present invention, the first cleaning robot further comprises: the water tank, the water tank is used for the storage washing liquid, and first kind cleaning machines people can be through spray set with the washing liquid spouts ground, and cleaning assembly 100 can clear up the ground that has the washing liquid to can promote the cleaning performance of first kind cleaning machines people to ground. 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 ground, when the amount of water in the water tank is reduced, the matching effect of the cleaning surface 10a and the ground can be still ensured, thereby ensuring the cleaning effect of the first cleaning robot on the ground.

It should be noted that, the existing robot is provided with a water tank, and the cleaning part of the robot is attached to the ground by using the self weight, however, the pressure of the cleaning part on the ground is gradually reduced as the cleaning liquid in the water tank gradually flows out, and the sufficient contact between the cleaning part and the ground cannot be ensured, so that the cleaning effect of the robot on the ground is affected.

A cleaning machines people in this application is provided with cleaning assembly 100, and cleaning assembly 100 can push down cleaning portion 10 through pushing down subassembly 30 when rotating cleaning portion 10 and clearing up ground, with cleaning surface 10a and ground laminating, guarantees that cleaning portion 10 is less to the clearance effect on ground, receives the change of first cleaning machines people 100 self weight to influence.

The cleaning assembly 100 of the present application is also applicable to a second type of cleaning robot that cleans a surface that is non-horizontal, e.g., a window glass surface, as compared to the first type of cleaning robot which cleans the surface as a floor surface, in which case the second type of cleaning robot may be a window wiper. When the cleaning assembly 100 performs a cleaning operation, the cleaning assembly cannot convert the self weight of the cleaning part 10 and the water tank arranged on the cleaning part 10 into the friction force between the cleaning surface 10a and the cleaning surface, at this time, when the driving assembly 20 drives the cleaning part 10 to rotate, the pressing assembly 30 synchronously rotates along with the driving part, 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 comprises: when the suction device (not shown) ensures that the cleaning surface is not horizontal, the second cleaning robot can still keep working to clean the cleaning surface.
