It should be noted that the rotation axis of the driving member 10 is vertically arranged relative to the bottom surface of the housing 200; and the driving member 10 may employ a motor.

In practical applications, the specific structure of the side brush 30 may be determined according to practical situations, such as a single-side brush structure, a double-side brush structure, or a three-side brush structure, and the like, and the specific structure is not limited herein as long as the side brush can be smoothly contacted with the surface to be cleaned for cleaning when cleaning is needed, and can be maintained in a state of being separated from the surface to be cleaned when cleaning is not needed.

Also, the side brush 30 may be provided on the driving member 10 and may be rotated with respect to the elevation structure 20, or the side brush 30 may be provided on the bottom surface of the housing 200 and may be rotated with respect to the elevation structure 20.

When the lifting structure 20 rotates in the first direction, the lifting structure 20 can lift the bristles 31 of the side brush 30 in a planar lifting manner, so that the bristles 31 are separated from the surface to be cleaned; alternatively, the lifting structure 20 can lift the bristles 31 of the side brush 30 in a grabbing manner, so that the bristles 31 are separated from the surface to be cleaned; still alternatively, the lifting structure 20 may lift the bristles 31 of the side brush member 30 in a sucking manner to detach the bristles 31 from the surface to be cleaned, and the like.

In an embodiment, the side brush 30 can rotate relative to the lifting structure 20, when the bristles 31 of the side brush 30 are lifted by the lifting structure 20, the side brush 30 can be driven to continue to rotate in the first direction by the lifting structure 20, and when the bristles 31 of the side brush 30 are released by the lifting structure 20 to contact with the surface to be cleaned, the side brush 30 can be driven to continue to rotate in the second direction by the lifting structure 20; at this time, the driving member 10 may be provided with only one rotating shaft, so that the rotating shaft drives the lifting structure 20 to rotate.

In another embodiment, the side brush 30 can rotate relative to the lifting structure 20, and the specific driving member 10 may include two rotating shafts, one rotating shaft is a hollow shaft, the other rotating shaft is a solid shaft, the hollow shaft is sleeved outside the solid shaft, and the rotating shafts of the two rotating shafts coincide, wherein the two rotating shafts can respectively drive the lifting structure 20 and the side brush 30 to rotate, as long as the lifting structure 20 and the side brush 30 can rotate relative to each other.

Further, referring to fig. 1 and 2 in combination, in an embodiment of the edge brush mechanism 100 of the present invention, the rotation axis of the edge brush member 30 coincides with the rotation axis of the lifting structure 20. So set up, including a rotation axis when the driving piece, and after the brush hair 31 of limit brush piece 30 was lifted by lifting structure 20, alright drive limit brush piece 30 through lifting structure 20 and continue to rotate with the first direction, after brush hair 31 of limit brush piece 30 was released by lifting structure 20 and is waited to clean the surface contact, specifically also can drive limit brush piece 30 through lifting structure 20 and continue to rotate with the second direction.

So set up, when need not cleaning, driving piece 10 will drive lifting structure 20 and rotate with first direction, and brush hair 31 will slide in lifting plane 220, just through lifting plane 220 lifting brush hair 31 to make brush hair 31 break away from the surface of treating to clean, so, just need not additionally to increase the structure of snatching or absorbing the structure of the locking of brush hair 31 lifting, and, can avoid causing the damage to brush hair 31 in the in-process of snatching or absorbing repeatedly through the mode of lifting plane 220 lifting.

Further, referring to fig. 1 and fig. 2 in combination, in an embodiment of the edge brush mechanism 100 of the present invention, the lifting structure 20 includes a lifting member 21 and a limiting member 22, the lifting member 21 is connected to the driving member 10 and has the lifting plane 220, the limiting member 22 is disposed on the lifting plane 220 and has a first limiting surface 221 and a second limiting surface 222 that are disposed opposite to each other; when the lifting piece 21 rotates in the first direction, the brush bristles 31 slide into the lifting plane 220 and abut against the first limiting surface 221; when the lifting member 21 rotates in the second direction, the bristles 31 slide out of the lifting plane 220 and abut against the second limiting surface 222.

With such an arrangement, when the surface to be cleaned does not need to be cleaned, the driving member 10 drives the lifting member 21 to rotate in the first direction, and the bristles 31 slide into the lifting plane 220 of the lifting member 21 and abut against the first limiting surface 221. At this time, the bristles 31 of the side brush 30 are lifted by the lifting planes 220 so that the bristles 31 of the side brush 30 do not contact the surface to be cleaned to be maintained in a state of being separated from the surface to be cleaned. When the surface to be cleaned needs to be cleaned, the driving member 10 drives the lifting member 21 to rotate in the second direction, the bristles 31 slide out of the lifting plane 220 of the lifting member 21 and abut against the second limiting surface 222, at this time, the bristles 31 are not limited in the height direction and contact the surface to be cleaned, and when the driving member 10 drives the lifting member 21 to continue to rotate in the second direction, the side brush member 30 can be pushed to rotate under the limiting effect of the second limiting surface 222, so that the surface to be cleaned is cleaned through the bristles 31 of the side brush member 30.

It should be noted that the limiting member 22 is convexly disposed on the lifting plane 220 of the lifting member 21 and extends toward the bottom surface of the casing 200, and the first limiting surface 221 and the second limiting surface 222 are both disposed at an included angle with the bottom surface of the casing 200, so that the bristles 31 of the side brush member 30 are abutted against the first limiting surface 221 or the second limiting surface 222 during the rotation process of the lifting member 21.

Referring to fig. 2, in an embodiment of the edge brush mechanism 100 of the present invention, the first position-limiting surface 221 and the second position-limiting surface 222 are perpendicular to the bottom surface of the housing 200.

With such an arrangement, when the driving member 10 drives the lifting member 21 to rotate in the first direction, the bristles 31 of the side brush member 30 slide into the lifting plane 220 of the lifting member 21 and abut against the first limiting surface 221, and since the first limiting surface 221 is perpendicular to the bottom surface of the housing 200, the contact area between the first limiting surface 221 and the bristles 31 can be increased, so that the bristles 31 are sufficiently abutted by the first limiting surface 221, and the bristles 31 can be better maintained in a state of being separated from the surface to be cleaned. Similarly, when the driving member 10 drives the lifting member 21 to rotate in the second direction, the bristles 31 of the side brush 30 slide out of the lifting plane 220 of the lifting member 21 and abut against the second limiting surface 222, and since the second limiting surface 222 is perpendicular to the bottom surface of the housing 200, the contact area between the bristles 31 and the second limiting surface 222 can be increased, so that the bristles 31 are sufficiently abutted by the second limiting surface 222, the side brush 30 is pushed to rotate under the limiting action of the second limiting surface 222, and the surface to be cleaned can be cleaned by the bristles 31.

Referring to fig. 5 and fig. 8, in an embodiment of the edge brush mechanism 100 of the present invention, the first position-limiting surface 221 and the second position-limiting surface 222 are both disposed to extend along a radial direction of a rotation track of the driving member 10; that is, the limiting member 22 is a fan-shaped structure disposed on the lifting plane 220, and the first limiting surface 221 and the second limiting surface 222 are two opposite sides of the fan-shaped structure, so that when the brush bristles 31 abut against the first limiting surface 221, the contact area between the first limiting surface 221 and the brush bristles 31 is further increased, thereby further increasing the limiting strength of the first limiting surface 221 to the brush bristles 31, and similarly, when the brush bristles 31 abut against the second limiting surface 222, the contact area between the second limiting surface 222 and the brush bristles 31 is further increased, thereby further increasing the limiting strength of the second limiting surface 222 to the brush bristles 31.

It should be noted that the extending direction of the first position-limiting surface 221 is a third direction, and the extending direction of the second position-limiting surface 222 is a fourth direction. The rotation locus of the driver 10 is a circle surrounded by the rotation of the driver 10 around the rotation axis.

Optionally, the limiting member 22 and the lifting member 21 are of an integral structure, so that the forming process is simplified, and the connection strength between the limiting member 22 and the lifting member 21 is improved. In practical application, the composite material can be integrally formed by adopting an injection molding process. In other embodiments, the limiting member 22 and the lifting member 21 may be provided separately, for example, the limiting member 22 is detachably fixed on the lifting member 21 by a fastener.

Referring to fig. 2, in an embodiment of the edge brush mechanism 100 of the present invention, the lifting element 21 includes a connecting portion 211 and a lifting portion 212; the connecting part 211 is connected to the driving element 10; the lifting part 212 is connected to an outer circumference of the connection part 211 and has the lifting plane 220.

With such an arrangement, during the assembly process, the lifting member 21 can be connected to the driving member 10 through the connecting portion 211, so that the driving member 10 drives the lifting member 21 to rotate, and meanwhile, the lifting portion 212 is connected to the outer periphery of the connecting portion 211, so that the bristles 31 can slide into the lifting plane 220 of the lifting portion 212 and abut against the first limiting surface 221, or the bristles 31 slide out of the lifting plane 220 of the lifting portion 212 and abut against the second limiting surface 222 during the rotation process of the lifting member 21.

Optionally, the connecting portion 211 and the lifting portion 212 are of an integral structure, so that the forming process is simplified, and the connecting strength between the connecting portion 211 and the lifting portion 212 is improved.

Further, referring to fig. 2 in combination, in an embodiment of the edge brush mechanism 100 of the present invention, the lifting portion 212 includes a first lifting portion 2121 and a second lifting portion 2122; the first uplifting part 2121 is connected to the outer periphery of the connecting part 211 and extends along the radial direction of the rotation track of the driver 10, and the first uplifting part 2121 has a first uplifting surface facing the bottom surface of the housing 200; the second lifting portion 2122 is connected to an end of the first lifting portion 2121 away from the connecting portion 211, and extends along the second direction, the second lifting portion 2122 has a second lifting surface facing the bottom surface of the casing 200, the first lifting surface and the second lifting surface form the lifting plane 220, and the limiting member 22 is disposed on the second lifting surface.

In the rotation process of the lifting member 21, since the first lifting portion 2121 extends along the radial direction of the rotation track of the driving member 10, and the second lifting portion 2122 extends along the second direction, the bristles 31 can smoothly slide into the first lifting surface of the first lifting portion 2121, then slide into the second lifting surface of the second lifting portion 2122, and finally abut against the first limiting surface 221, so that the bristles 31 can conveniently slide into the lifting plane 220.

Optionally, the first lifting portion 2121 and the second lifting portion 2122 are an integral structure, so that the molding process is simplified, and the connection strength between the first lifting portion 2121 and the second lifting portion 2122 is improved.

Further, referring to fig. 2, in an embodiment of the edge brush mechanism 100 of the present invention, a side of the first elevation part 2121 facing away from the extending direction of the second elevation part 2122 has a guide surface 2121a, and the guide surface 2121a is connected to the elevation plane 220 for the bristles 31 to pass over and guide to the elevation plane 220.

During the rotation of the lifting member 21, the bristles 31 smoothly pass over the guide surfaces 2121a and are smoothly guided to the lifting plane 220 by the guide surfaces 2121a, so that the bristles 31 more smoothly slide into the lifting plane 220.

In some embodiments, referring to fig. 2 in combination, in an embodiment of the edge brush mechanism 100 of the present invention, the first lifting surface is inclined gradually upward along a radial outward direction of the rotation track of the driving member 11; the second lifting surface is inclined upward in a direction from an end of the second lifting portion 2122 close to the first lifting portion 2121 to an end thereof far from the first lifting portion 2121.

With such an arrangement, when the lifting member 21 rotates in the first direction, the bristles 31 smoothly slide the first lifting surface, which is obliquely arranged, onto the second lifting surface, and then smoothly slide the second lifting surface, which is obliquely arranged, into the second lifting surface to abut against the first limiting surface 221; similarly, when the lifting member 21 rotates in the second direction, the brush bristles 31 smoothly slide out from the second inclined lifting surface to the first inclined lifting surface, and then slide out from the first inclined lifting surface to contact with the second limiting surface 222.

Note that "upward" refers to a side toward the casing 200.

Further, referring to fig. 2, in an embodiment of the edge brush mechanism 100 of the present invention, the limiting element 22 is disposed at an end of the second lifting portion 2122 away from the first lifting portion 2121.

With such an arrangement, when the bristles 31 slide over the first lifting surface and slide into the second lifting surface during the rotation of the lifting member 21, the bristles 31 can be supported on the first lifting surface and abut against the first limiting surface 221, so that the bristles 31 are maintained in a state of being separated from the surface to be cleaned; after the brush hairs 31 sequentially slide out of the second lifting surface and the first lifting surface, the brush hairs 31 are not limited in the height direction and contact the surface to be cleaned, and the brush hairs 31 abut against the second limiting surface 222, so that the brush hairs 31 are pushed to rotate under the limiting action of the second limiting surface 222 to clean the surface to be cleaned.

Further, referring to fig. 2 in combination, in an embodiment of the edge brush mechanism 100 of the present invention, the second limiting surface 222 is flush with an end surface of the second raised portion 2122 away from the first raised portion 2121.

With such an arrangement, in the rotation process of the lifting element 21, after the brush bristles 31 slide out of the lifting plane 220, the brush bristles 31 can partially abut against the second limiting surface 222 and partially abut against an end surface of the second lifting portion 2122, which is far away from the first lifting portion 2121, so as to further improve the limiting strength of the brush bristles 31.

In order to improve the cleaning effect of the surface to be cleaned, referring to fig. 1 and fig. 2, in an embodiment of the edge brush mechanism 100 of the present invention, at least two of the lifting portions 212 are provided, at least two of the lifting portions 212 are spaced apart from each other along the circumferential direction of the rotation track of the driving member 10, and an avoiding space 210 is formed between two adjacent lifting portions 212; one limiting member 22 is arranged on each lifting plane 220; the side brush member 30 has at least two bristles 31, at least two bristles 31 are arranged at intervals along the circumference of the rotation track of the driving member 10, and each escape space 210 is used for correspondingly accommodating one bristle 31;

the lifting piece 21 rotates, so that each bristle 31 slides into one of the lifting planes 220 and abuts against one of the first limiting surfaces 221; alternatively, the lifting member 21 rotates, so that each bristle 31 slides out to one escape space 210 and abuts against one second limiting surface 222.

With such arrangement, when the surface to be cleaned needs to be cleaned, the driving part 10 drives the lifting part 21 to rotate, so that each bristle 31 slides out from the lifting plane 220 of one lifting part 21 to an avoidance space 210 and abuts against the second limiting surface 222 of one limiting part 22, at this time, at least two bristles 31 are not limited in the height direction and contact the surface to be cleaned, and at least two bristles 31 can be respectively pushed to rotate under the limiting effect of the at least two second limiting surfaces 222, so that the surface to be cleaned is cleaned through the at least two bristles 31, and thus the cleaning effect of the surface to be cleaned is effectively improved.

It should be noted that the respective structures (e.g., the driving member 10, the lifting portion 212, the brush 31, etc.) are described in an assembled state (i.e., a state where the side brush mechanism 100 is assembled to the housing 200 of the cleaning robot 1000).

In order to ensure that the side brush 30 can rotate relative to the driving member 10, referring to fig. 1, in an embodiment of the side brush mechanism 100 of the present invention, the side brush 30 has a mounting ring 32, the lifting structure 20 is circumferentially fixed to the driving member 10, the driving member 10 has a driving shaft 11, and the mounting ring 32 is sleeved on the driving shaft 11 and can rotate relative to the driving shaft 11.

When the surface to be cleaned needs to be cleaned, the driving shaft 11 drives the lifting piece 21 to rotate, so that the bristles 31 slide out of the lifting plane 220 of the lifting piece 21 and abut against the second limiting surface 222, in the process, the side brush piece 30 rotates relative to the driving shaft 11, namely, the side brush piece 30 does not move, and when the lifting piece 21 continues to rotate, the side brush piece 30 is pushed to rotate together under the limiting effect of the second limiting surface 222; similarly, when the surface to be cleaned is not required to be cleaned, the driving shaft 11 drives the lifting member 21 to rotate, so that the bristles 31 slide into the lifting plane 220 and abut against the first limiting surface 221, in the process, the side brush 30 rotates relative to the driving shaft 11, that is, the side brush 30 is stationary, and when the lifting member 21 continues to rotate, the side brush 30 is pushed to rotate together under the limiting action of the first limiting surface 221.

Alternatively, in another embodiment, the side brush member 30 has a mounting ring 32, and the rotor of the driving member 10 has an annular groove (not shown) disposed around the rotation axis of the driving member 10, and the mounting ring 32 is engaged with and rotatable relative to the annular groove in the annular groove.

Similarly, when the surface to be cleaned needs to be cleaned, the driving member 10 drives the lifting member 21 to rotate, so that the bristles 31 slide out of the lifting plane 220 of the lifting member 21 and abut against the second limiting surface 222, in the process, the side brush 30 rotates relative to the driving member 10 under the matching of the mounting ring 32 and the annular groove, that is, the side brush 30 is not moved, and when the lifting member 21 continues to rotate, the side brush 30 is pushed to rotate together under the limiting action of the second limiting surface 222; similarly, when the surface to be cleaned is not required to be cleaned, the driving member 10 drives the lifting member 21 to rotate, so that the bristles 31 slide into the lifting plane 220 and abut against the first limiting surface 221, in the process, the side brush 30 rotates relative to the driving member 10 through the cooperation of the mounting ring 32 and the annular groove, that is, the side brush 30 is not moved, and when the lifting member 21 continues to rotate, the side brush 30 is pushed to rotate together under the limiting action of the first limiting surface 221.

Further, in an embodiment, the bristles 31 are connected to the outer periphery of the mounting ring 32, so that the bristles 31 are prevented from being connected to the top or bottom of the mounting ring 32, which results in a large space occupied by the side brush 30 and thus a large overall space occupied by the side brush mechanism 100, and is not favorable for realizing a miniaturized design.

The utility model further provides a cleaning robot 1000, the cleaning robot 1000 includes a housing 200 and an edge brush mechanism 100, the specific structure of the edge brush mechanism 100 refers to the above embodiments, and since the cleaning robot 1000 adopts all technical solutions of all the above embodiments, at least all beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here. The side brush mechanism 100 is disposed at the bottom of the casing 200.
