[0047] The exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present utility model and to fully convey the scope of the present utility model to those skilled in the art.

[0048] A cleaning robot, also known as a floor sweeping robot or an automatic cleaning machine, etc., can automatically complete the cleaning work of the ground. It usually has side brushes arranged on the side of the bottom. The side brushes are mainly used to clean the corners that are difficult to clean, such as the corners of walls and the edges of furniture. Moreover, the side brushes can also rotate and sweep by rubbing against the ground, pushing the garbage towards the suction port of the cleaning robot to improve the cleaning effect.

[0049] However, the side brushes of most current cleaning robots are always in contact with the ground, resulting in easy contamination of the side brushes when the cleaning robot cleans liquid dirt. And when the cleaning robot passes over the cleaned ground, the contaminated side brushes are likely to contaminate the ground again.

[0050] Based on the above technical problems, embodiments of the present utility model are proposed. The embodiments of the present utility model may include a side brush housing 1, a side brush transmission member 2, and a side brush assembly 3. A receiving cavity 1001 is provided inside the side brush housing 1. The side brush transmission member 2 is vertically installed in the receiving cavity 1001, and a first abutting surface 20211 and a second abutting surface 20212 are provided along the circumference of the side brush transmission member 2. The side brush assembly 3 penetrates through the side brush housing 1, and the side brush assembly 3 includes a protruding column 301. The first abutting surface 20211 and the second abutting surface 20212 are respectively used to abut against the protruding column 301, and drive the side brush assembly 3 to flip through the abutting force. Thus, when the cleaning robot sweeps liquid dirt or is in the single mopping mode, the side brush assembly 3 can be flipped away from the ground, avoiding the side brush assembly 3 from contacting the dirt, and improving the cleanliness of the side brush device.

[0051] Referring to Figures 1-10 , embodiments of the present utility model provide a side brush device. The side brush device may include a side brush housing 1, a side brush transmission member 2, and a side brush assembly 3. A receiving cavity 1001 is provided inside the side brush housing 1. The side brush transmission member 2 is vertically installed in the receiving cavity 1001, and a first abutting surface 20211 and a second abutting surface 20212 are provided along the circumference of the side brush transmission member 2. The side brush assembly 3 penetrates through the side brush housing 1, and the side brush assembly 3 includes a protruding column 301. The first abutting surface 20211 and the second abutting surface 20212 are respectively used to abut against the protruding column 301, and drive the side brush assembly 3 to flip through the abutting force. Thus, when the cleaning robot sweeps liquid dirt or is in the single mopping mode, the side brush assembly 3 can be flipped away from the ground, avoiding the side brush assembly 3 from contacting the dirt, and improving the cleanliness of the side brush device.

[0052] In the embodiments of the present utility model, a receiving cavity 1001 is opened inside the side brush housing 1, and the receiving cavity 1001 is used for installing the side brush transmission member 2 and the side brush assembly 3. Among them, the side brush assembly 3 penetrates through the side brush housing 1. It can also be understood that the front end of the side brush assembly 3 is located in the receiving cavity 1001, and the end of the side brush assembly 3 is located outside the side brush housing 1. The side brush assembly 3 is arranged along the circumference of the side brush housing 1. The side brush assembly 3 may further include side brush bristles 304, and the side brush bristles 304 are mainly used for ground cleaning and are located at the end outside the side brush housing 1. Thus, the rotation of the side brush transmission member 2 or the rotation of the side brush housing 1 can drive the rotation of the side brush assembly 3 and drive the side brush bristles 304 to perform ground cleaning.

[0053] A protruding column 301 is further provided on the side brush transmission member 3. Among them, the side brush transmission member 2 is vertically installed in the accommodation cavity 1001, and a first abutting surface 20211 and a second abutting surface 20212 are provided on the circumferential direction of the side brush transmission member 2. The first abutting surface 20211 and the second abutting surface 20212 are used to abut against the protruding column 301 respectively, so as to provide a force to the protruding column 301 through the first abutting surface 20211 or the second abutting surface 20212, or to apply a force to the first abutting surface 20211 or the second abutting surface 20212 through the protruding column 301. Thus, under the action of the abutting force, the protruding column 301 drives the side brush assembly 3 to flip. Thus, the ground clearance height of the side brush assembly 3 is changed. To prevent the side brush assembly 3 from contacting dirt, the cleanliness of the side brush device is improved, and the cleaning effect of the side brush device is improved.

[0054] In some embodiments, the side brush assembly 3 may further include a side brush curved arm 302, and the side brush curved arm 302 has a certain bending angle. Referring to FIGS. 1 and Figure 2 As shown, when the side brush assembly 3 is in the descending state, the side brush assembly 3 is bent downward. Under the action of the abutting force, after the protruding column 301 drives the side brush assembly 3 to flip by a certain angle, the bending direction of the side brush curved arm 302 changes, so as to lift the height of the side brush bristles 304 located on the side brush curved arm 302.

[0055] The number of the side brush assemblies 3 provided is at least two, and at least two side brush assemblies 3 are equally angularly distributed about the central axis of the side brush transmission member 2 in the horizontal circumferential direction of the side brush housing 1. As a preferred embodiment, the number of the side brush assemblies 3 can be set to three.

[0056] An alternative utility model embodiment, referring to Figure 7 As shown, the side brush transmission member 2 includes a transmission body 201 and a transmission abutting portion 202 extending radially along the transmission body 201. A transmission abutting groove 2021 is formed on the transmission abutting portion 202, so that two side walls of the transmission abutting groove 2021 respectively form the first abutting surface 20211 and the second abutting surface 20212.

[0057] In the embodiment of the present utility model, the side brush transmission member 2 may include a transmission body 201 and a transmission abutting portion 202, and the transmission abutting portion 202 extends radially along the transmission body 201. The transmission body 201 and the transmission abutting portion 202 may be an integral structure. Moreover, on the transmission abutting portion 202, a transmission abutting groove 2021 for defining the position of the side brush crank arm 302 is formed radially along the transmission body 201. Two side walls of the transmission abutting groove 2021 along the circumferential direction of the transmission body 201 are respectively used as a first abutting surface 20211 and a second abutting surface 20212. The protruding post 301 abuts against the first abutting surface 20211 or the second abutting surface 20212.

[0058] Thus, a force is provided to the protruding post 301 through the first abutting surface 20211 or the second abutting surface 20212, or a force is exerted on the first abutting surface 20211 or the second abutting surface 20212 through the protruding post 301. So that under the action of the abutting force, the protruding post 301 drives the side brush assembly 3 to flip. Wherein, both the first abutting surface 20211 and the second abutting surface 20212 may be inclined surfaces.

[0059] In some alternative embodiments of the utility model, referring to Figure 1 、 Figure 4 and Figure 5 as shown, the side brush housing 1 includes a first housing 101 and a second housing 102 located below the first housing 101, and the first housing 101 and the second housing 102 cooperate to form the accommodating cavity 1001. At least two limiting rib strips 4 are arranged on the second housing 102. Among them, every two limiting rib strips 4 cooperate to form a limit on the protruding post 301 to limit the flipping angle of the side brush crank arm 302.

[0060] In the embodiment of the present utility model, the side brush housing 1 may also include a first housing 101 and a second housing 102. Wherein, the second housing 102 is located below the first housing 101, so that through the up-and-down assembly of the first housing 101 and the second housing 102, the accommodating cavity 1001 is formed. In some implementation manners, the first housing 101 and the second housing 102 may be connected by means of welding, bonding, clamping, etc. No excessive limitation is made here. For example, positioning structures and through holes for assembling the side brush crank arm 302 may also be arranged on the end faces of the first housing 101 and the second housing 102 that are close to each other.

[0061] At least two limiting rib strips 4 are provided on the second housing 102. Among them, the number of the limiting rib strips 4 is associated with the number of the side brush crank arms 302. For example, when the number of the side brush crank arms 302 is N, the corresponding number of the limiting rib strips 4 is 2N, etc. Thus, every two limiting rib strips 4 can be arranged at intervals, and the two cooperate to form a circumferential position limit for the stud 301 along the transmission body 201. Thus, during the flipping process of the side brush crank arm 302, the stud 301 abuts against the first limiting rib strip 4, or the stud 301 abuts against the second limiting rib strip 4 to limit the flipping angle of the side brush crank arm 302. For example, the flipping angle can be less than or equal to 90°.

[0062] An optional embodiment of the utility model, referring to Figure 5 and Figure 8 As shown, a side brush clamping groove 1021 is provided on the second housing 102. The side brush assembly 3 may further include a side brush clamping portion 303. Among them, the side brush clamping portion 303 is connected to the side brush crank arm 302, and the side brush clamping groove 1021 and the side brush clamping portion 303 cooperate to form a radial limit for the side brush crank arm 302 along the transmission body 201.

[0063] In the embodiment of the present utility model, the side brush clamping portion 303 is used to limit the side brush crank arm 302 in the radial position along the transmission body 201. For example, a side brush clamping groove 1021 is provided on the second housing 102, and the side brush clamping portion 303 and the side brush clamping groove 1021 cooperate. Thus, it is possible to prevent the side brush crank arm 302 from displacing in the radial direction along the transmission body 201 during the flipping process. For example, the front end (a part close to the transmission body 201) of the side brush crank arm 302 can be a cylindrical structure, or the front end of the side brush crank arm 302 can be a conical structure, or the front end of the side brush crank arm 302 is a frustum structure, etc. Thus, it can be ensured that the outer edge of the axial section of the front end of the side brush crank arm 302 along the transmission body 201 is circular, and it is only necessary to ensure that the front end of the side brush crank arm 302 can rotate around the same axis, and no more limitations are made here.

[0064] The central axis of the side brush clamping portion 303 coincides with the flipping central axis of the side brush crank arm 302, and the cross-sectional shape of the side brush clamping portion 303 along the flipping central axis can be an annular shape or a part of an annular shape.

[0065] In some alternative embodiments, the side brush crank arm 302, the side brush card-connecting portion 303, and the stud 301 can be of an integral structure. They can be made of materials such as metal, plastic, and rubber. The side brush bristle bundle 304 at the end of the side brush crank arm 302 can also be made of materials such as rubber and plastic.

[0066] In some other alternative utility model embodiments, the side brush housing 1 includes a first housing 101 and a second housing 102 located on the side of the first housing 101. The first housing 101 and the second housing 102 cooperate to form the accommodation cavity 1001. At least two limiting rib strips 4 are provided on the first housing 101 and / or the second housing 102. Among them, every two limiting rib strips 4 cooperate to limit the stud 301, so as to define the flipping angle of the side brush crank arm 302.

[0067] In the embodiments of the present utility model, the side brush housing 1 can also include a first housing 101 and a second housing 102. Among them, the second housing 102 is located on the side of the first housing 101, so that the accommodation cavity 1001 is formed by the left-right assembly of the first housing 101 and the second housing 102. In some embodiments, the first housing 101 and the second housing 102 can be connected by means such as welding, bonding, and snap connection. No further limitation is made here. For example, a positioning structure and a through hole for assembling the side brush crank arm 302 can also be provided on the end faces of the first housing 101 and the second housing 102 that are close to each other.

[0068] When there is one side brush crank arm 302, two limiting rib strips 4 can be provided at the bottom of the first housing 101 or the bottom of the second housing 102. Thus, every two limiting rib strips 4 can be arranged at intervals, and the two cooperate to define the position of the stud 301 along the circumferential direction of the transmission body 201. Thus, during the flipping process of the side brush crank arm 302, the stud 301 abuts against the first limiting rib strip 4, or the stud 301 abuts against the second limiting rib strip 4, to define the flipping angle of the side brush crank arm 302. For example, the flipping angle can be less than or equal to 90°.

[0069] As a preferred embodiment of the utility model, the flipping angle can be 90°. Thus, when the bending direction of the side brush crank arm 302 is flipped to the horizontal direction, the side brush bristle bundle 304 is lifted to the highest position.

[0070] When there are at least two side brush curved arms 302, two limiting rib strips 4 can be respectively arranged at the bottom of the first housing 101 and the bottom of the second housing 102. Wherein, the number of the limiting rib strips 4 is associated with the number of the side brush curved arms 302. For example, when the number of the side brush curved arms 302 is N, the corresponding number of the limiting rib strips 4 is 2N, etc.

[0071] In an alternative embodiment of the utility model, a side brush clamping groove 1021 is arranged on the first housing 101 and / or the second housing 102. The side brush assembly 3 may include a side brush curved arm 302 and a side brush clamping portion 303. Wherein, the side brush clamping portion 303 is connected to the side brush curved arm 302 to cooperate with the side brush clamping portion 303 through the side brush clamping groove 1021 to form radial limitation on the side brush curved arm 302 along the radial direction of the transmission body 201.

[0072] In the embodiment of the present utility model, when there is one side brush curved arm 302, a side brush clamping groove 1021 can be arranged at the bottom of the first housing 101 or the bottom of the second housing 102. The side brush clamping portion 303 is used to define the radial position of the side brush curved arm 302 along the transmission body 201. For example, the side brush clamping portion 303 cooperates with the side brush clamping groove 1021. Thereby, it is possible to prevent the side brush curved arm 302 from displacing along the radial direction of the transmission body 201 during the flipping process.

[0073] For example, the front end (a part close to the transmission body 201) of the side brush curved arm 302 can be a cylindrical structure, or the front end of the side brush curved arm 302 can be a conical structure, or the front end of the side brush curved arm 302 is a frustum structure, etc. Thereby, it can be ensured that the outer edge of the axial section of the front end of the side brush curved arm 302 along the transmission body 201 is circular, and it is only necessary to ensure that the front end of the side brush curved arm 302 can rotate around the same axis, and no more limitations are made here.

[0074] In some alternative embodiments of the utility model, referring to Figure 1 、 Figure 4 、 Figure 9 and Figure 10 as shown, the side brush device may further include an elastic member 5 sleeved on the transmission body 201. The first end of the elastic member 5 is fixed to the transmission abutting portion 202, and the second end 501 is fixed to the first housing 101. Through the deformation recovery of the elastic member 5, the first abutting surface 20211 or the second abutting surface 20212 forms an abutment with the stud 301 to drive the side brush assembly 3 to flip and reset.

[0075] In an embodiment of the present utility model, the elastic member 5 is sleeved on the side brush transmission member 2, and its two ends are respectively fixed to the side brush transmission member 2 and the side brush housing 1. Refer to Figure 1 and Figure 4 As shown, the elastic member 5 may include a torsion spring. The first end (not marked in the figure) of the elastic member 5 is fixed to the side brush transmission member 2, and the second end 501 of the elastic member 5 is fixed to the side brush housing 1. Thus, through the elastic member 5, the side brush transmission member 2 and the side brush housing 1 are elastically connected along the circumferential direction of the transmission body 201.

[0076] Thus, the protruding column 301 is driven to rotate by the first abutting surface 20211 or the second abutting surface 20212. Or, when the protruding column 301 drives the first abutting surface 20211 or the second abutting surface 20212 to rotate. After the external force is withdrawn, the elastic potential energy accumulated by the elastic member 5 is released, so that the first abutting surface 20211 or the second abutting surface 20212 applies a force to the protruding column 301, enabling the protruding column 301 to drive the side brush bent arm 302 to flip under the action of the abutting force, thereby causing the height of the side brush assembly 3 to decrease. For example, the bending direction of the side brush bent arm 302 is flipped from the horizontal direction to vertically downward, so that the side brush bristles 304 are restored to the cleaning state of contacting the ground. Thus, when the cleaning robot cleans liquid dirt or operates in the single mopping mode, the side brush assembly 3 can be flipped away from the ground by the flipping mode of the side brush assembly 3, avoiding the side brush assembly 3 from contacting the dirt and improving the cleanliness of the side brush device.

[0077] An alternative embodiment of the utility model, refer to Figure 7 As shown, an elastic accommodation groove 2001 is provided between the side brush transmission member 2 and the transmission abutting portion 202. The elastic member 5 is embedded in the elastic accommodation groove 2001, and the first end of the elastic member 5 is radially clamped on the transmission abutting portion 202. Wherein, the second end 501 of the elastic member 5 is radially clamped on the first housing 101 or the second housing 102.

[0078] In the embodiments of the present utility model, in order to ensure the axial stability of the elastic member 5, an elastic accommodation groove 2001 is provided between the side brush transmission member 2 and the transmission abutting portion 202, or it can be understood as at the connection between the side brush transmission member 2 and the transmission abutting portion 202. When the elastic member 5 is sleeved on the side brush transmission member 2, the elastic accommodation groove 2001 can axially limit and radially limit the elastic member 5 along the axis of the transmission body 201. Additionally, an elastic limit groove for defining the position of the elastic member 5 is provided on the first housing 101 or the second housing 102. Thus, displacement of the elastic member 5 in the axial direction of the transmission body 201 can be avoided, and displacement of the elastic member 5 in the radial direction of the transmission body 201 can be avoided.

[0079] Referring to Figure 1 , Figure 4 , Figure 6 and Figure 7 as shown, a first clamping groove 2022 is further formed on the transmission abutting portion 202, and the first end of the elastic member 5 is radially clamped in the first clamping groove 2022 of the transmission abutting portion 202. And a second clamping groove 1002 is further formed on the first housing 101 or the second housing 102, and the second end of the elastic member 5 is radially clamped in the second clamping groove 1002. Thus, during the rotation of the elastic member 5, it can deform radially along the transmission body 201.

[0080] An alternative embodiment of the utility model, referring to Figure 9 and Figure 10 , a threaded through hole 2002 is formed in the vertical direction of the transmission body 201. The side brush device may further include a threaded connecting member 6 and a transmission shaft 7. The threaded connecting member 6 is threadedly connected to the transmission body 201 through the threaded through hole 2002. The transmission shaft 7 is coaxially arranged with the transmission body 201, and the transmission shaft 7 is connected to the threaded connecting member 6 to drive the transmission body 201 to rotate through the transmission shaft 7.

[0081] A threaded connection hole 7001 is formed on the end face of the transmission shaft 7. The threaded connecting member 6 cooperates with the threaded connection hole 7001 to form a fixed connection between the transmission shaft 7 and the transmission body 201.

[0082] In the embodiments of the present utility model, the transmission shaft 7 is coaxially fixed to the transmission body 201 and is used to drive the transmission body 201 to rotate. The threaded connecting member 6 penetrates through the central axis of the transmission body 201. On the one hand, the threaded connecting member 6 serves as the rotation axis of the transmission body 201. On the other hand, the threaded connecting member 6 is used for the fixed connection with the transmission shaft 7 and also serves as a power input component.

[0083] The threaded through hole 2002 and the threaded connection hole 7001 are coaxially arranged, that is, the central axis of the threaded through hole 2002 coincides with the central axis of the threaded connection hole 7001. To improve the connection stability between the transmission shaft 7 and the side brush transmission member 2, the threaded connecting member 6 can be used to penetrate the side brush transmission member 2 completely from the bottom of the side brush transmission member 2 and be threadedly connected to the threaded connection hole 7001, so as to realize the fixed connection between the transmission shaft 7 and the side brush transmission member 2.

[0084] In the embodiment of the present utility model, in order to facilitate the installation of the threaded connecting member 6, relevant holes can be opened in the corresponding assembly areas of the first housing 101 and / or the second housing 102, which will not be limited too much here. The threaded connecting member 6 can be a connecting member such as a screw or a bolt.

[0085] In an alternative embodiment of the utility model, referring to Figure 10 As shown, the side brush device further includes a second gear 8 and a one-way transmission member 9. The second gear 8 is sleeved on the transmission shaft 7 and is coaxially fixed to the transmission shaft 7 to drive the transmission shaft 7 to rotate through the second gear 8. The one-way transmission member 9 is fixed to the side brush housing 1. Wherein, when the second gear 8 rotates forward, it drives the side brush transmission member 2 to rotate, and the first abutting surface 20211 abuts against the protruding column 301 to drive the side brush housing 1 to rotate synchronously. When the second gear 8 rotates reversely, it drives the side brush transmission member 2 to rotate, and the protruding column 301 moves to abut against the second abutting surface 20212. Under the abutting force of the second abutting surface 20212 and the locking force of the one-way transmission member 9 on the side brush housing 1, the protruding column 301 drives the side brush curved arm 302 to flip.

[0086] In the embodiment of the present utility model, the second gear 8 being coaxially fixed to the transmission shaft 7 means that the central axis of the second gear 8 coincides with the central axis of the transmission shaft 7 and forms a fixed connection. Thus, when the second gear 8 is acted on by an external force, it drives the transmission shaft 7 to rotate and drives the side brush transmission member 2 fixedly connected to the transmission shaft 7 to rotate. The one-way transmission member 9 is fixedly connected to the side brush housing 1. For example, the one-way transmission member 9 can be a one-way bearing, which has a one-way locking function and limits the side brush housing 1 to rotate only in one of the rotation directions of the transmission member body 201.

[0087] When the second gear 8 rotates forward, the side brush transmission member 2 rotates forward synchronously. At this time, the first abutment surface 20211 forms an abutment with the protruding column 301, and drives the side brush housing 1 and the side brush transmission member 2 to rotate forward synchronously through the abutment force, thereby realizing the rotation of the side brush assembly 3, and at this time the side brush assembly 3 can perform normal floor cleaning.

[0088] When the second gear 8 is reversed, the side brush transmission member 2 is reversed synchronously. At this time, the protruding column 301 is converted from being in contact with the first abutting surface 20211 to being in contact with the second abutting surface 20212. And due to the locking effect of the one-way transmission member 9 on the side brush housing 1, the second abutting surface 20211 applies a circumferential force along the transmission body 201 to the protruding column 301. As a result, the protruding column 301 is flipped by the toggle and the height of the side brush assembly 3 from the bottom surface is raised. At this time, the elastic member 5 is deformed and compressed. When the second gear 8 rotates forward next time, due to the elastic deformation recovery of the elastic member 5, after the second abutting surface 20211 cancels the abutting force on the protruding column 301, the first abutting surface 20211 forms abutment with the protruding column 301 again, and the floor cleaning operation is repeated. Therefore, when the cleaning robot is cleaning liquid dirt or performing single mopping mode, the side brush assembly 3 can be flipped to keep the side brush assembly 3 away from the ground, thereby preventing the side brush assembly 3 from contacting dirt and improving the cleanliness of the side brush device.

[0089] In another optional utility model embodiment, referring to Figure 9 As shown, the side brush device may further include a second gear 8 and a one-way transmission member 9, wherein the second gear 8 is sleeved on the transmission shaft 7 and movably connected to the transmission shaft 7, wherein the second gear 8 is fixed to the side brush housing 1 so as to drive the side brush housing 1 to rotate through the second gear 8. The one-way transmission member 9 is fixed to the transmission shaft 7. Wherein, if the second gear 8 rotates forward, driving the side brush housing 1 to rotate, the protruding column 301 abuts against the first abutting surface 20211 and drives the side brush transmission member 2 to rotate. If the second gear 8 rotates reversely, driving the side brush housing 1 to rotate, the protruding column 301 moves to abut against the second abutting surface 20212, and under the abutting force of the second abutting surface 20212 and the locking force of the one-way transmission member 9 on the side brush transmission member 2, the protruding column 301 drives the side brush curved arm 302 to flip.

[0090] In the embodiment of the utility model, the second gear 8 is movably connected to the transmission shaft 7, which means that the rotation of the second gear 8 does not directly drive the transmission shaft 7 to rotate. For example, the movably connected may be a clearance fit, a sliding connection, etc. Thus, when the second gear 8 is subjected to an external force, the side brush housing 1 is driven to rotate. The one-way transmission member 9 is fixedly connected to the transmission shaft 7. For example, the one-way transmission member 9 may be a one-way bearing, which has a one-way locking function, which limits the side brush transmission member 2 to rotate only in one of the rotation directions.

[0091] When the second gear 8 rotates forward, the side brush housing 1 rotates forward synchronously. At this time, the first abutment surface 20211 abuts against the protruding column 301, and the abutment force generated by the protruding column 301 drives the side brush transmission member 2 to rotate forward synchronously, thereby realizing the rotation of the side brush assembly 3, and at this time, the side brush assembly 3 can perform normal floor cleaning.

[0092] When the second gear 8 is reversed, the side brush housing 1 is reversed synchronously. At this time, the protruding column 301 is converted from being in contact with the first abutting surface 20211 to being in contact with the second abutting surface 20212. And due to the locking effect of the one-way transmission member 9 on the side brush housing 1, the second abutting surface 20211 applies a circumferential force along the transmission body 201 to the protruding column 301. As a result, the protruding column 301 is flipped by the toggle and the height of the side brush assembly 3 from the bottom surface is raised. At this time, the elastic member 5 is deformed and compressed. When the second gear 8 rotates forward next time, due to the elastic deformation recovery of the elastic member 5, after the second abutting surface 20211 cancels the abutting force on the protruding column 301, the first abutting surface 20211 forms abutment with the protruding column 301 again, and the floor cleaning operation is repeated. Therefore, when the cleaning robot is cleaning liquid dirt or performing single mopping mode, the side brush assembly 3 can be flipped to keep the side brush assembly 3 away from the ground, thereby preventing the side brush assembly 3 from contacting dirt and improving the cleanliness of the side brush device.

[0093] In the above embodiment, the rotary motion output device 10 is connected to the second gear 8 for outputting rotary motion and driving the second gear 8 to rotate. When the second gear 8 is coaxially fixed with the transmission shaft 7 and the one-way transmission member 9 is fixed with the side brush housing 1, the rotary motion output device 10 rotates forward and drives the second gear 8 to rotate forward, and the side brush transmission member 2 rotates forward synchronously. At this time, the first abutting surface 20211 abuts against the protruding column 301, and drives the side brush housing 1 and the side brush transmission member 2 to rotate forward synchronously through the abutting force, thereby realizing the rotation of the side brush assembly 3, and at this time, the side brush assembly 3 can perform normal floor cleaning.

[0094] When the rotary motion output device 10 reverses, the second gear 8 is driven to reverse, and the side brush transmission member 2 reverses synchronously. At this time, the protruding column 301 is converted from abutting with the first abutting surface 20211 to abutting with the second abutting surface 20212. And due to the reverse locking effect of the one-way transmission member 9 on the side brush housing 1, the one-way transmission member 9 and the side brush housing 1 are relatively displaced, and the second abutting surface 20211 applies a circumferential force along the transmission body 201 to the protruding column 301. As a result, the protruding column 301 is flipped by the toggle, and the height of the side brush assembly 3 from the bottom surface is raised. At this time, the elastic member 5 is deformed and compressed. And when the side brush assembly 3 is lifted to the highest point, the rotary motion output device 10 stops rotating.

[0095] When the second gear 8 rotates forward next time, the elastic deformation of the elastic member 5 is restored, and after the second abutting surface 20211 cancels the abutting force on the protruding column 301, the first abutting surface 20211 abuts against the protruding column 301 again, and the floor cleaning operation is repeated. Therefore, when the cleaning robot is cleaning liquid dirt or performing a single mopping mode, the side brush assembly 3 can be flipped to keep the side brush assembly 3 away from the ground, thereby preventing the side brush assembly 3 from contacting dirt and improving the cleanliness of the side brush device.

[0096] When the second gear 8 is coaxially fixed with the side brush housing 1, and the one-way transmission member 9 is fixed with the transmission shaft, the rotational motion output device 10 rotates forward, driving the second gear 8 to rotate forward, and the side brush housing 1 rotates forward synchronously. At this time, the first abutting surface 20211 abuts against the protruding column 301, and the abutting force generated by the protruding column 301 drives the side brush transmission member 2 to rotate forward synchronously, thereby realizing the rotation of the side brush assembly 3, and at this time, the side brush assembly 3 can perform normal floor cleaning.

[0097] When the rotary motion output device 10 is reversed, the second gear 8 is driven to reverse, and the side brush housing 1 is reversed synchronously. At this time, the protruding column 301 is converted from abutting with the first abutting surface 20211 to abutting with the second abutting surface 20212. And due to the reverse locking effect of the one-way transmission member 9 on the side brush housing 1, the one-way transmission member 9 and the side brush housing 1 are relatively displaced, and the second abutting surface 20211 applies a circumferential force along the transmission body 201 to the protruding column 301. Thereby, the protruding column 301 is flipped by the toggle, and the height of the side brush assembly 3 from the bottom surface is raised. At this time, the elastic member 5 is deformed and compressed. And when the side brush assembly 3 is lifted to the highest point, the rotary motion output device 10 stops rotating. When the second gear 8 rotates forward next time, the elastic deformation of the elastic member 5 is restored, and after the second abutting surface 20211 cancels the abutting force on the protruding column 301, the first abutting surface 20211 abuts against the protruding column 301 again, and the floor cleaning operation is repeated. Therefore, when the cleaning robot is cleaning liquid dirt or performing a single mopping mode, the side brush assembly 3 can be flipped to keep the side brush assembly 3 away from the ground, thereby preventing the side brush assembly 3 from contacting dirt and improving the cleanliness of the side brush device.

[0098] Other transmission structures may be used for power transmission between the rotational motion output device 10 and the second gear 8. For example, the side brush device may further include a gear set 11, and the gear set 11 may include at least one power gear, so that the gear set 11 is meshed with the second gear 8, and the output shaft of the rotational motion output device 10 is coaxially fixed with the power gear for power input in the gear set 11. The rotational motion output device 10 may include a motor and other devices.

[0099] In summary, the embodiment of the utility model discloses a side brush device, which may include a side brush housing 1, a side brush transmission member 2 and a side brush assembly 3. The side brush housing 1 is provided with a housing cavity 1001. The side brush transmission member 2 is vertically installed in the housing cavity 1001, and a first abutting surface 20211 and a second abutting surface 20212 are provided along the circumference of the side brush transmission member 2. The side brush assembly 3 is arranged through the side brush housing 1, and the side brush assembly 3 includes a protruding column 301. The first abutting surface 20211 and the second abutting surface 20212 are respectively used to abut against the protruding column 301, and drive the side brush assembly 3 to flip through the abutting force. Therefore, when the cleaning robot cleans liquid dirt or performs a single mopping mode, the side brush assembly 3 can be flipped to keep the side brush assembly 3 away from the ground, thereby preventing the side brush assembly 3 from contacting dirt, thereby improving the cleanliness of the side brush device.

[0100] An embodiment of the present utility model also discloses a cleaning robot, which may include a side brush device as described in any one of the above-mentioned utility model embodiments.
