As a possible embodiment, as shown in fig. 2, the side brush assembly 2 may include a plurality of side brush assemblies 2, and the plurality of side brush assemblies 2 are spaced around the main body 1. It should be understood that fig. 2 shows an edge brush of a mobile cleaning device including three edge brush assemblies 2, but this is merely an example, and the number of the edge brush assemblies 2 is determined according to the actual application scenario, which is not limited by the embodiment of the present invention.

As can be seen in fig. 2, the main body 1 may have a top portion 11 rotatably connected to the mobile cleaning device, a bottom portion 12 opposite the top portion 11, and a first direction z directed from the bottom portion 12 to the top portion 11.

Further, as shown in fig. 2, the winding portion 23 may be a bent portion 231 extending from a side wall of the main body portion 1 in a direction away from the main body portion 1, and in this case, the bending direction of the bent portion 231 may be along the first direction z. As can be seen from fig. 2, the two opposite sides of the bending portion 231 are symmetrically bent, but the bending form is not limited to this, and in other embodiments, the bending portion 231 may be bent at any one of the two opposite sides. It should be noted that even if the bending portion 231 is not bent at the opposite two sides, that is, the winding portion 23 is an extending portion without bending characteristics extending from the side wall of the main body portion 1 to the direction away from the main body portion 1, the winding effect of the winding portion 23 will not be affected, so what kind of structural form the winding portion 23 specifically adopts is determined according to the actual application scenario, and the embodiment of the present invention does not limit this.

As a possible embodiment, both sides of the bent portion 231 in the extending direction of the bent portion 231 may include a rough surface; or both sides of the protruding part in the extending direction of the protruding part may include rough surfaces. That is, the boundary of the bent portion 231 in the first direction z includes a rough surface, or both side boundaries of the protruding portion include rough surfaces. Specifically, the rough surface may include a serrated relief structure or a surface having a large friction such as a frosted finish. The friction force between the rough surface and the long and thin garbage such as hair is larger than the friction force between the garbage and the first side brush 21 and the second side brush 22, so that the garbage can be drawn out of the first side brush 21 and the second side brush 22, the clamping stop of the mobile cleaning equipment can be effectively avoided, and the cleanliness of the mobile cleaning equipment is improved. It should be understood that only a portion of the boundary of the two corresponding sides of the bent portion 231 or the extended portion may include a rough surface to reduce the difficulty of removing the garbage from the winding portion 23, and certainly, the two corresponding sides of the bent portion 231 or the extended portion may also include all rough surfaces to improve the ability of the winding portion 23 to extract the garbage.

As another possible embodiment, both sides of the winding part 23 in the extending direction of the winding part 23 include a cut part. Specifically, both sides of the bending portion 231 along the extending direction of the bending portion 231 include cut portions; or the protruding part includes cut parts on both sides in the extending direction of the protruding part. That is, the boundary of the bending portion 231 in the first direction z includes the cut portion, or both side boundaries of the protruding portion include the cut portions. Specifically, the cutting portion may have a sharp edge, and the cutting portion may be configured to cut long and thin garbage, such as hairs, on the first side brush 21 and the second side brush 22 into short garbage to implement cleaning, so as to prevent the garbage, such as hairs, from being too long and being entangled around the cleaning device.

As a possible implementation, the width of the end of the bending part 231 close to the main body part 1 may be greater than the width of the end of the bending part 231 far from the main body part 1; or the width of the end of the extension portion close to the main body portion 1 may be larger than the width of the end of the extension portion far from the main body portion 1. That is, the width of the bending portion 231 or the extending portion decreases from the end close to the main body portion 1 to the end far from the main body portion 1. The bent part 231 or the extending part with gradually changing width can prevent garbage such as hair from approaching the main body part 1 during cleaning to affect the normal operation of the main body part 1 (for example, the hair enters the main body part 1 to cause jamming), and the bent part 231 or the extending part with gradually changing width can be used to facilitate the garbage removal from the winding part 23. It should be understood that the bent portion 231 or the protruding portion may be provided to have a width closer to one end of the main body portion 1 larger than that farther from one end of the main body portion 1 while both sides in the extending direction include rough surfaces.

As a possible embodiment, the winding portion 23 includes guide portions on both sides in the extending direction of the winding portion 23. Specifically, the two sides of the bending part 231 along the extending direction of the bending part 231 include guide parts extending to the garbage suction port; or the two sides of the extending part along the extending direction of the extending part comprise guide parts extending to the garbage suction port. By providing the guide portion, the garbage such as hair wound around the winding portion 23 can be guided to the garbage suction port to be cleaned, and the cleaning effect can be improved.

Furthermore, the first side brush 21 may extend from the main body 1 in a direction away from the main body 1, and the extending direction x of the first side brush 21 forms a first included angle β with the plane of the bottom of the main body 1; similarly, the second side brush 22 may extend from the main body 1 in a direction away from the main body 1, and the extending direction y of the second side brush 22 forms a second included angle α with the plane of the bottom of the main body 1.

Preferably, the length of the second side brush 22 in the extending direction of the second side brush 22 is 9 mm to 25 mm greater than the length of the first side brush 21 in the extending direction of the first side brush 21. For example, the length of the second side brush 22 may be set to 54 mm and the length of the first side brush 21 may be set to 45 mm to avoid interference between the first side brush 21 and the second side brush 22.

Specifically, the first side brush 21 may include first bristles 211, and the first bristles 211 may be directly connected (e.g., embedded, etc.) to the main body 1; the second side brush 22 may include a connection portion 221 extending in a direction away from the main body 1, a fixing portion 222 extending in a direction away from the main body 1 from one end of the connection portion 221 away from the main body 1, and second brush bristles 223 connected (e.g., fitted) to the fixing portion 222. It should be understood that the first bristles 211 of the first side brush 21 and the second bristles 223 of the second side brush 22 are both members that are in direct contact with the debris to be cleaned.

More specifically, the connecting portion 221 of the second side brush 22 may be made of a rigid material or a flexible material, and preferably, the connecting portion 221 made of the flexible material can ensure a necessary range for the second side brush 22 to clean the garbage, which is beneficial to the cleaning of the second side brush 22. In order to avoid the length of the second side brush 22 in the extending direction y of the second side brush 22 from affecting the cleaning operation of the second side brush 22, the length of the fixing portion 222 in the second side brush 22 in the extending direction y of the fixing portion 222 may be greater than 10mm and less than or equal to 20 mm.

Of course, the structure of the first side brush 21 and the second side brush 22 is not limited to the structure described above, and as shown in fig. 3 and 4, in other embodiments, the first side brush 21 may include the first bristle 211 and the fastening portion 212 extending from the main body portion 1 in a direction away from the main body portion 1, in which case, the first bristle 211 may be directly connected (e.g., embedded) to one end of the fastening portion 212 away from the main body portion 1; the second side brush 22 may include a torsion portion 224 extending from the main body portion 1 in a direction away from the main body portion 1, and second bristles 223 connected to one end of the torsion portion 224 away from the main body portion 1, wherein the torsion portion 224 has an axis along the extending direction of the torsion portion 224, the torsion portion 224 is twisted with the axis as a reference, and a socket 2241 may be formed at one end of the torsion portion 224 away from the main body portion 1, in which case, the second bristles 223 may be connected (e.g., fitted into) the socket 2241.

Preferably, the torsion portion 224 of the second side brush 22 is made of an elastic material. As can be seen from the foregoing description, the torsion portion 224 is connected to the second brush bristles 223 by the way of the insertion holes 2241, that is, the torsion portion 224 and the second brush bristles 223 are not integrated, and in this case, the torsion portion 224 can be used as a resilient bending arm. Then in practical application, when the second brush hairs 223 connected with the twisting portion 224 contact with larger particulate garbage, the second brush hairs 223 can be ensured not to be easily forked due to the effect of the twisting portion 224, and the cleaning effect is effectively improved.

It can be understood that the material of the connecting portion 221 in the second side brush 22, the length of the fixing portion 222 along the extending direction y, the length of the second bristle 223 along the extending direction y, the length of the first bristle 211 in the first side brush 21 along the extending direction x, and the like are determined according to practical application scenarios, and the embodiment of the present invention is not limited thereto.
