Description

Side brush module and cleaning robot

Technical Field

Along with the development of automation technology and artificial intelligence, the demand of intelligent cleaning robot is more and more extensive, and cleaning robot can effectively improve sanitation, has greatly reduced cleaning personnel's working strength.

The front end of the intelligent cleaning robot in the walking direction is generally provided with a side brush. When cleaning, the side brush is contacted with the surface to be cleaned and rotates relative to the surface to be cleaned, so that the garbage on the surface to be cleaned is rolled and swept. In order to ensure the cleaning effect, the side brush needs to be inclined relative to the surface to be cleaned, and the side brush sweeps the garbage on the inclined side to the non-inclined side in a rolling manner, so that the garbage is gathered. Wherein, the inclined side is the side of the brush body closer to the surface to be cleaned.

The existing lifting mechanism is generally adopted to drive the side brush to move towards the direction close to or far away from the surface to be cleaned, and the rotation of the side brush is realized while the side brush is lifted, so that the side brush is inclined to a preset angle relative to the surface to be cleaned. However, since the side brush and the lifting mechanism have a large weight, the side brush is inevitably inclined or shaken during the lifting process, and the inclination angle of the side brush relative to the surface to be cleaned is affected, thereby affecting the cleaning effect and the service life of the side brush. It is common to provide a guide structure to guide the lifting movement of the lifting assembly. However, the existing guide structure has a limited guide effect on the lifting assembly, and the lifting assembly and the side brush still incline or shake in the lifting process.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 and 2, the present embodiment provides an edge brush module 100, which can be configured on a cleaning robot for cleaning a surface to be cleaned. Specifically, the side brush module 100 is generally installed at the front end of the traveling direction of the cleaning robot and is disposed at the bottom of at least one side of the cleaning robot. When the cleaning device works, the side brush module 100 inclines relative to a surface to be cleaned, the inclined side of the side brush module 100 is contacted with the surface to be cleaned, and the non-inclined side is separated from the surface to be cleaned. The side brush module 100 rotates relative to the surface to be cleaned to sweep the garbage on the inclined side to the non-inclined side, so that the garbage is gathered. Wherein, the inclined side is the side of the side brush module 100 closer to the surface to be cleaned. Specifically, for the cleaning robot, the inclined side is the side of the side brush module 100 facing the outside of the cleaning robot, and the non-inclined side is the side of the side brush module 100 facing the inside of the cleaning robot, and the side brush module 100 guides the garbage on the surface to be cleaned backwards and inwards. The rear of the side brush module 100 can be optionally provided with a rolling brush module, and the rolling brush module further rolls the garbage into a dust collecting box. The rear part of the rolling brush module is optionally provided with a water absorption rake for absorbing sewage on a surface to be cleaned and ensuring that the surface to be cleaned is clean and has no water mark.

Specifically, as shown in fig. 1 to 4, the edge brush module 100 includes a lifting assembly 4 and an edge brush assembly 1. The lifting assembly 4 serves as a mounting carrier for the edge brush module 100. The lifting assembly 4 can drive the side brush module 100 to lift, i.e. move towards or away from the surface to be cleaned. When the lifting component 4 drives the side brush component 1 to move towards the direction close to the surface to be cleaned, the side brush component 1 can contact with the surface to be cleaned so as to realize cleaning. Illustratively, referring to fig. 8 and 10, the edge brush assembly 1 includes an edge brush 11, and the edge brush 11 includes a brush body 111 and a plurality of bristle parts 112 arranged along a circumferential direction of the brush body 111. The bristle parts 112 are all inclined downward to form an approximately umbrella-like structure. The ends of the bristle portion 112 are used to contact the surface to be cleaned to sweep the waste.

Further, referring to fig. 1 to 7, the side brush assembly 1 is rotatably mounted on the lifting assembly 4, and the side brush assembly 1 includes a first triggering part 721 and a second triggering part 31. When the lifting assembly 4 drives the side brush assembly 1 to lift, the first triggering portion 721 is lifted relative to the second triggering portion 31, and when the first triggering portion 721 contacts with the second triggering portion 31, the first triggering portion 721 drives the side brush assembly 1 to rotate and tilt relative to the lifting assembly 4, i.e. the side brush assembly 1 tilts relative to the surface to be cleaned, so as to clean. Illustratively, when the side brush assembly 1 does not need to be cleaned, the side brush assembly 1 is parallel to the surface to be cleaned or is not inclined at a proper angle. When needing to clean, lifting unit 4 drives limit brush subassembly 1 to the direction motion of being close to the face of waiting to clean, and first portion 721 that triggers contacts with second portion 31, and limit brush subassembly 1 rotates the slope for lifting unit 4 under the drive of first portion 721 that triggers simultaneously to make limit brush subassembly 1 for waiting to clean the face and incline to predetermineeing inclination, in order to treat and clean the face.

In this embodiment, the first triggering portion 721 is elevated relative to the second triggering portion 31, and when the first triggering portion 721 contacts with the second triggering portion 31, the first triggering portion 721 drives the edge brush assembly 1 to rotate and incline relative to the lifting assembly 4, so that the edge brush assembly 1 inclines to a preset inclination angle relative to the surface to be cleaned, thereby cleaning the surface to be cleaned.

In this embodiment, the first triggering part 721 is disposed on the edge brush assembly 1, that is, the first triggering part 721 and the edge brush assembly 1 are lifted synchronously; the second trigger part 31 is arranged on the cleaning robot body 3, namely, the absolute position of the second trigger part 31 is unchanged in the process of lifting the side brush assembly 1; so that the first triggering part 721 can contact with the second triggering part 31 as the edge brush assembly 1 ascends and descends. The cleaning robot body 3 serves as a bearing structure of the cleaning robot, and other necessary structures such as other cleaning modules (such as a rolling brush module, a water absorption raking module and the like) and walking wheels can be arranged on the cleaning robot body.

In this embodiment, the first triggering portion 721 includes a protrusion, and the second triggering portion 31 includes a rotating member, and the protrusion can contact with the rotating member. Specifically, the protruding direction of the protrusion forms an included angle with the lifting direction of the side brush assembly 1. The rotating member is located in the direction in which the projection ascends or descends. When the lifting component 4 ascends or descends, the side brush component 1 ascends or descends along with the lifting component. Before the projection is not contacted with the rotating part, the movement of the side brush assembly 1 and the lifting assembly 4 is completely the same, and the side brush assembly 1 is parallel to the surface to be cleaned or the inclined angle is not in place. When the bulge is contacted with the rotating piece, the bulge is blocked by the rotating piece along with the lifting motion of the side brush component 1; in order to continuously rise or fall, the protrusions exert certain extrusion force and tangential force on the rotating piece under the driving of the side brush assembly 1, and the rotating piece rotates under the action of the tangential force; the protruding then can drive limit brush subassembly 1 and rotate for lifting unit 4 under the effect of the reaction force of rotating the piece to can cross the stopping of rotating the piece and continue rising or descending along with lifting unit 4, make limit brush subassembly 1 for waiting to clean the face slope to predetermineeing the angle simultaneously, in order to clean.

Specifically, referring to fig. 4-7, the projection includes a top end a, an upper end b, and a lower end c. The top end a is the end of the projection facing away from the side brush assembly 1. The upper end b and the lower end c are both positioned at the root of the bulge and are respectively arranged at the two opposite ends of the bulge in the lifting direction. The convex outer profile includes a first profile S1 and a second profile S2. The first profile S1 extends from the apex a of the projection to the lower end c thereof. The second profile S2 extends from the apex a of the projection to its upper end b. By providing the first contour S1 and the second contour S2, the protrusions are ensured to be able to be stably and effectively contacted with the rotating member, thereby ensuring the rotating smoothness of the side brush assembly 1 relative to the lifting assembly 4. Further, the protrusions are alternately contacted with the rotation member through the first profile S1 and the second profile S2, so that the rotation and alignment of the edge brush assembly 1 with respect to the lifting assembly 4 can be achieved, as will be described in detail below.

The lifting assembly 4 has upper and lower extreme positions which are opposite up and down. When the side brush module 100 does not need to perform cleaning work, the lifting assembly 4 is located at the upper limit position, and the side brush assembly 1 is separated from the surface to be cleaned so as to avoid influencing the normal walking of the cleaning robot; optionally, at this time, the edge brush assembly 1 is parallel to or at a certain included angle with the surface to be cleaned (the included angle is smaller than the preset inclined angle, and when the edge brush assembly 1 contacts with the surface to be cleaned at the included angle, the cleaning effect cannot be guaranteed, that is, the edge brush assembly 1 is not inclined in place relative to the surface to be cleaned).

When the side brush assembly 1 is needed to clean, the lifting assembly 4 descends and drives the side brush assembly 1 to move towards the direction close to the surface to be cleaned. The movement of the side brush assembly 1 and the lifting assembly 4 is identical before the protrusions are not in contact with the rotating member. As the lifting assembly 4 continues to descend, the lower end c of the projection first contacts the rotating member. The rotor rotates about its own axis under the action of the projections, and in order to continue the descent of the edge brush assembly 1, the points of the first contour S1 of the projections from its lower end c to its top end a come into contact with the rotor in sequence, as a result of which: the protrusion drives the side brush assembly 1 to rotate and incline relative to the lifting assembly 4, and the rotation angle of the side brush assembly 1 relative to the lifting assembly 4 is increased continuously, that is, the side brush assembly 1 inclines relative to the first direction of the surface to be cleaned, and the included angle is increased continuously. When the side brush assembly 1 is inclined to a preset inclination angle relative to the surface to be cleaned and the end part of the bristle part 112 at the inclined side is in contact with the surface to be cleaned, the cleaning work can be performed.

It can be understood that when the protrusion contacts the rotating member through the first contour S1, specifically when the top end a of the protrusion contacts the rotating member, the inclination angle (not less than the preset inclination angle) of the side brush assembly 1 relative to the surface to be cleaned is the largest, and at this time, the lifting assembly 4 can be controlled to stop descending, and the side brush assembly 1 starts cleaning; or before the top end a of the protrusion is not contacted with the rotating part (at the moment, the side brush assembly 1 is inclined to the preset inclined angle relative to the surface to be cleaned), the lifting assembly 4 is controlled to stop descending, and the side brush assembly 1 starts cleaning.

In one embodiment, after the cleaning of the side brush assembly 1 is finished, the lifting assembly 4 can be controlled to ascend, the side brush assembly 1 and the protrusion ascend, and the protrusion moves reversely relative to the rotating member through the first contour S1, so that the side brush assembly 1 rotates reversely relative to the lifting assembly 4, that is, the side brush assembly 1 inclines in a second direction (opposite to the first direction) relative to the surface to be cleaned, and the inclination angle of the side brush assembly 1 relative to the surface to be cleaned gradually decreases. When lifting unit 4 rose to extreme position, limit brush subassembly 1 reverted to initial condition, and limit brush subassembly 1 is parallel or is certain contained angle with treating the cleaning surface promptly, and limit brush subassembly 1 with treat the separation of cleaning surface, avoid influencing cleaning robot's walking.

In another embodiment, when the protrusion contacts the rotating member through the first contour S1 and when the top end a of the protrusion contacts the rotating member (when the angle of inclination of the side brush assembly 1 with respect to the surface to be cleaned is the largest), the lifting assembly 4 is controlled to continue to descend, and the protrusion contacts the rotating member through the points from the top end a to the top end b of the protrusion on the second contour S2 in sequence, as a result: the protrusion drives the side brush assembly 1 to rotate reversely relative to the lifting assembly 4, namely, the side brush assembly 1 inclines towards the second direction (opposite to the first direction) relative to the surface to be cleaned, and the inclination angle of the side brush assembly 1 relative to the surface to be cleaned is reduced. When the lifting component 4 descends to the lower limit position, the protrusion is separated from the rotating component, and the side brush component 1 is parallel to the surface to be cleaned.

Alternatively, when the lifting assembly 4 is lowered to the lower limit position and is parallel to the surface to be cleaned, two further cases can be distinguished: 1. the side brush assembly 1 is contacted with a surface to be cleaned; 2. the edge brush assembly 1 is separated from the surface to be cleaned.

In case 1, this is a conventional practice in the prior art, and the present embodiment will not be described in too much.

In case 2, as shown in fig. 1, 2, 4-10, the cleaning pad assembly 2 can be disposed at the bottom of the side brush assembly 1, specifically, at the bottom end surface of the brush body 111, i.e., the cleaning pad assembly 2 is located at the inner side of the approximately umbrella-shaped structure formed by the plurality of bristle parts 112. Specifically, since the cleaning pad assembly 2 has a certain thickness, it is possible to prevent the end portion of the bristle part 112 from extending to the surface to be cleaned when the bottom end surface of the cleaning pad assembly 2 is brought into close contact with the surface to be cleaned, i.e., when the side brush assembly 1 is separated from the surface to be cleaned while being parallel to the surface to be cleaned, only the cleaning pad assembly 2 is operated. Meanwhile, since the radius of the bottom surface of the approximately umbrella-shaped structure formed by the plurality of bristle parts 112 is greater than the radius of the cleaning pad assembly 2, the cleaning pad assembly 2 is separated from the surface to be cleaned when the side brush assembly 1 is lifted and tilted with respect to the surface to be cleaned, while the bottom surface of the approximately umbrella-shaped structure formed by the plurality of bristle parts 112 is tilted with respect to the surface to be cleaned and the end of the inclined side bristle part 112 is in contact with the surface to be cleaned, only the brush assembly 1 is operated at this time.

That is, in case 2, by adding the cleaning pad assembly 2 to the bottom of the edge brush assembly 1, the whole edge brush module 100 has the following states during the process of the lifting assembly 4 descending from the upper limit position to the lower limit position: 1) a stop state, in which the edge brush module 100 is not performing a cleaning operation (see fig. 5, the lifting assembly 4 is located at the upper limit position); 2) the working state of the side brush assembly (see fig. 6, the lifting assembly 4 descends from the upper limit position, the protrusion contacts with the rotating member through the first contour S1, the inclination angle of the side brush assembly 1 relative to the surface to be cleaned is continuously increased, and the brush part 112 at the inclined side contacts with the surface to be cleaned); 3) the side brush assembly 1 is gradually separated from the surface to be cleaned, and the cleaning pad assembly 2 is gradually attached to the surface to be cleaned (the lifting assembly 4 continuously descends, the protrusion is contacted with the rotating part through the second contour S2, the inclination angle of the side brush assembly 1 relative to the surface to be cleaned is continuously reduced, the brush hair part 112 at the inclined side is gradually separated from the surface to be cleaned, and the bottom surface of the cleaning pad assembly 2 is gradually attached to the surface to be cleaned); 4. the cleaning pad assembly is in operation (see fig. 7, the upper end b of the projection is in contact with the rotating member, i.e. the projection is separated from the rotating member, the lifting assembly 4 is lowered to the lower limit position, and the bottom surface of the cleaning pad assembly 2 is completely attached and clings to the surface to be cleaned). That is, in the process of descending the lifting assembly 4, the switching between the working state of the side brush assembly and the working state of the cleaning pad assembly can be realized.

The side brush assembly 1 works first to clean large-particle garbage on the surface to be cleaned first, and then the cleaning pad assembly 2 works to clean and wipe small-particle garbage on the surface to be cleaned and garbage adhered to the cleaning surface. The edge brush assembly 1 serves as a pre-cleaning module and the cleaning pad assembly 2 serves as a secondary cleaning module to enhance the cleaning effect. The limit brush subassembly 1 cleans in advance to cleaning pad subassembly 2, can avoid treating the large granule rubbish on the cleaning surface to destroy cleaning pad subassembly 2, improves the life of cleaning module. In addition, the edge brush assembly 1 and the cleaning pad assembly 2 are integrated into one cleaning module, which can effectively reduce the size of the product.

Illustratively, referring to fig. 8, the cleaning pad assembly 2 includes a mounting member 21 and a pad assembly 22. The pad assembly 22 is connected to the brush body 111 by the mounting member 21. The mounting member 21 may be engaged with the brush body 111, screwed, welded, etc., and is not limited thereto. The pad assembly 22 includes a hook plate 221 and a cleaning pad 222. The hook plate 221 is similar to a hook and loop fastener. The cleaning pad 222 is adhered to the hook surface of the hook plate 221. The smooth surface of the dial 221 is optionally bonded to the mounting member 21.

Further, after the cleaning pad assembly 2 is completed, the lifting assembly 4 is lifted from the lower limit position, the cleaning pad assembly 2 is separated from the surface to be cleaned, and the protrusions sequentially contact the rotating member through the points from the upper end b to the top end a on the second contour S2, as a result of the contact: the protrusion drives the side brush assembly 1 to rotate relative to the lifting assembly 4, namely, the side brush assembly 1 inclines towards the second direction relative to the surface to be cleaned, the inclination angle of the side brush assembly 1 relative to the surface to be cleaned is continuously increased, meanwhile, the end part of the brush hair part 112 on the inclined side is in contact with the surface to be cleaned, and the side brush assembly 1 can work or does not work at the moment. When the tip a of the projection comes into contact with the rotating member, the angle of inclination of the side brush assembly 1 with respect to the surface to be cleaned is maximized. The lifting assembly 4 continues to rise, and the protrusion then contacts the rotary member through the first profile S1, as a result of which: the bulge drives the side brush assembly 1 to rotate reversely relative to the lifting assembly 4, the side brush assembly 1 inclines towards the first direction relative to the surface to be cleaned, the inclination angle of the side brush assembly 1 relative to the surface to be cleaned is continuously reduced, and the side brush assembly 1 is separated from the surface to be cleaned. When the lifting assembly 4 is lifted to the upper limit position, the side brush assembly 1 and the cleaning pad assembly 2 are completely separated from the surface to be cleaned.

It can be understood that the inclination angle of the side brush assembly 1 relative to the surface to be cleaned can be ensured by designing the shape and size of the protrusion, and the cleaning effect can be further ensured.

Referring to fig. 3, in the present embodiment, the rotating member includes a roller. The roller is rotatably mounted on the cleaning robot body 3 through a connecting shaft. Obviously, the roller may be a complete wheel, a half wheel or a partial wheel, and is not limited herein, as long as it is ensured that the roller can contact with the protrusion during the ascending or descending process of the lifting assembly 4.

Further, referring to fig. 11 and 12, the plurality of protrusions are arranged in the embodiment, the plurality of protrusions are arranged at intervals along the axial direction of the rotating shaft of the rotating member, and the rotating member extends along the axial direction of the rotating shaft, so that the contact area between the protrusions and the rotating member is ensured, and the rotation stability of the side brush assembly 1 relative to the lifting assembly 4 is improved. In this embodiment, the rotating member is in the shape of a long cylinder.

In another embodiment, the protrusion is provided with one protrusion extending along the axial direction of the rotating shaft of the rotating member, so that the contact area between the protrusion and the rotating member can be ensured. In other another embodiment, the rotating part is provided with a plurality of rotating parts which are arranged at intervals along the axial direction of the rotating shaft, so that the contact area of the bulge and the rotating part can be ensured.
