Detailed implementation manners

[0053] 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 set forth herein. On the contrary, these embodiments are provided so that the present utility model can be more thoroughly understood and the scope of the present utility model can be completely conveyed to those skilled in the art.

[0054] 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 installed on the side of the bottom. The side brushes are mainly used to clean hard-to-reach corners 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.

[0055] However, the side brushes of most current cleaning robots are always in contact with the ground. When the cleaning robot cleans liquid dirt, such as cleaning liquid dirt like soy sauce or milk, it is easy to contaminate the side brushes. And when the cleaning robot passes over the cleaned ground, the contaminated side brushes are likely to cause secondary pollution to the ground.

[0056] Based on the above technical problems, the embodiments of the present utility model are proposed. The embodiments of the present utility model may include a side brush housing 1, a guide member 2, a side brush transmission member 3, and a side brush assembly 4. A receiving cavity 1001 is provided in the side brush housing 1. The guide member 2 is located in the receiving cavity 1001 and is fixed to the side brush housing 1. The side brush transmission member 3 is vertically installed in the receiving cavity 1001. The side brush assembly 4 passes through the side brush housing 1 and is connected to the side brush transmission member 3. Among them, the side brush assembly 4 abuts against the guide member 2 and drives the side brush assembly 4 to fold through the abutting force. Thus, when the cleaning robot cleans liquid dirt or is in a single mopping mode, the side brush assembly 4 can be folded away from the ground by the folding method of the side brush assembly 4, avoiding the side brush assembly 4 from contacting the dirt, improving the cleanliness of the side brush device, and avoiding secondary pollution during the ground cleaning process.

[0057] Refer to Figure 1-8 The embodiments of the present utility model provide a side brush device. The side brush device may include a side brush housing 1, a guide member 2, a side brush transmission member 3, and a side brush assembly 4. A receiving cavity 1001 is provided in the side brush housing 1. The guide member 2 is located in the receiving cavity 1001 and is fixed to the side brush housing 1. The side brush transmission member 3 is vertically installed in the receiving cavity 1001. The side brush assembly 4 passes through the side brush housing 1 and is connected to the side brush transmission member 3. Among them, the side brush assembly 4 abuts against the guide member 2 and drives the side brush assembly 4 to fold through the abutting force.

[0058] In an embodiment of the present utility model, the side brush device may include a side brush housing 1, a guide member 2, a side brush transmission member 3, and a side brush assembly 4. A receiving cavity 1001 is provided in the side brush housing 1 for installing the guide member 2, the side brush transmission member 3, and the side brush assembly 4. For example, the side brush transmission member 3 is vertically installed in the receiving cavity 1001, and the guide member 2 is installed in the receiving cavity 1001 and fixed to the side brush housing 1. The side brush assembly 4 penetrates through the side brush housing 1, which can be understood as part of the side brush assembly 4 being installed in the receiving cavity 1001 and part of the side brush assembly 4 being installed outside the side brush housing 1.

[0059] For example, the front end of the side brush assembly 4 is located in the receiving cavity 1001, and the end of the side brush assembly 4 is located outside the side brush housing 1. The side brush assembly 4 may also be fixed to the side brush transmission member 3, and the guide member 2 fixed on the side brush housing 1 forms an abutment with the side brush assembly 4. By the abutting force applied to the side brush assembly 4 by the guide member 2, the side brush assembly 4 is pressed down and folded to change the ground clearance of the side brush assembly 4.

[0060] Thus, when the cleaning robot is cleaning liquid dirt or in a single mopping mode, the side brush assembly 4 can be folded to keep the side brush assembly 4 away from the ground, avoiding contact between the side brush assembly 4 and the dirt, improving the cleanliness of the side brush device, and preventing secondary pollution during the process of cleaning the ground.

[0061] In an optional embodiment of the utility model, referring to Figure 5 、 Figure 8 、 Figure 9 and Figure 10 as shown, the guide member 2 is provided with an abutting inclined surface 201 along the axial direction of the side brush transmission member 3. Among them, the side brush assembly 4 includes a side brush curved arm 402, and the side brush curved arm 402 includes a side brush bending portion 4021, and the side brush bending portion 4021 abuts against the abutting inclined surface 201.

[0062] In the embodiment of the present utility model, the abutting inclined surface 201 is used to abut against the side brush curved arm 402. Wherein, the abutting inclined surface 201 is a surface formed by the height of the guiding member 2 (the distance between the connection of the guiding member 2 and the side brush housing 1 along the axial direction of the side brush transmission member 3 and the abutting inclined surface) gradually changing along the circumferential direction of the side brush transmission member 3. Thus, during the rotation of the side brush housing 1, through the relative rotation between the side brush housing 1 and the side brush transmission member 3, the height of the guiding member 2 changes, so as to gradually increase or decrease the abutting force of the abutting inclined surface 201 on the side brush curved arm 402, thereby enabling the side brush curved arm 402 to be pressed down to fold, or enabling the side brush curved arm 402 to fold back to its original position and return to the descending state again.

[0063] The side brush curved arm 402 has a certain bending angle. When the side brush assembly 4 is in the descending state, the bending direction of the side brush curved arm 402 is set to bend downward. When the side brush transmission member 3 and the side brush housing 1 move relative to each other, the guiding member 2 on the side brush housing 1 abuts against and presses down the side brush transmission member 3. For example, the guiding member 2 on the side brush housing 1 abuts against the side brush curved arm 402 downward, so that after driving the side brush curved arm 402 to fold downward, the bending direction of the side brush curved arm 402 changes. For example, the bending direction of the side brush curved arm 402 changes from bending downward to bending horizontally, so as to raise the height of the side brush curved arm 402. When the side brush curved arm 402 is in the raised state, the side brush assembly 4 can be away from the ground. Thus, when the cleaning robot cleans liquid dirt or operates in the single mopping mode, the side brush assembly 4 can be away from the ground through the folding method of the side brush assembly 4, avoiding the side brush assembly 4 contacting the dirt, improving the cleanliness of the side brush device and avoiding secondary pollution during the process of cleaning the ground.

[0064] In an optional embodiment of the utility model, referring to Figure 8 、 Figure 9 and Figure 12 as shown, the abutting inclined surface 201 includes a first abutting inclined surface 2011 and a second abutting surface 2012 connected to the first abutting inclined surface 2011. Wherein, when the side brush housing 1 rotates, the first abutting inclined surface 2011 abuts against the side brush bending part 4021, driving the side brush curved arm 402 to rotate, so as to enable the side brush assembly 4 to clean the ground. When the side brush housing 1 and the side brush transmission member 3 move relative to each other, the first abutting inclined surface 2011 forms an abutting guide for the side brush bending part 4021, so that the side brush bending part 4021 folds downward, raising the height of the side brush assembly 4. When the side brush assembly 4 is lifted to the highest position, the second abutting surface 2012 abuts against the side brush bending part 4021.

[0065] In the embodiment of the present utility model, the abutting inclined surface 201 includes a first abutting inclined surface 2011 and a second abutting surface 2012. Wherein, the second abutting surface 2012 is connected to the first abutting inclined surface 2011, or there is a smooth transition between the second abutting surface 2012 and the first abutting inclined surface 2011. Refer to Figure 8 As shown, when the side brush housing 1 rotates, the first abutting inclined surface 2011 of the guiding member 2 abuts against the side brush bending portion 402, so that the abutting force applied to the side brush bending portion 4021 by the guiding member 2 drives the side brush assembly 4 and the side brush transmission member 3 to rotate synchronously, so that the side brush assembly 4 remains in contact with the ground and performs ground cleaning. During the cleaning process of the side brush assembly 4, when encountering some large or thick garbage, due to the above-mentioned abutting force, the side brush assembly 4 remains pressed down and will not be turned up with the garbage, which can further improve the cleaning effect of the side brush assembly 4.

[0066] Refer to Figure 9 As shown, in the case of relative movement between the side brush housing 1 and the side brush transmission member 3, the first abutting inclined surface 2011 on the guiding member 2 forms an abutting guide for the side brush bending portion 4021. Among them, the abutting guide can be understood as that while the guiding member 2 abuts against the side brush bending portion 4021, the side brush bending portion 4021 moves along the first abutting inclined surface 2011 under the action of the abutting force. Thus, during the relative movement process through the abutting inclined surface 201, the abutting force on the side brush bending portion 4021 can be gradually increased, so that the side brush bending portion 4021 is pressed down and turned over downward, thereby changing the bending direction of the side brush curved arm 402.

[0067] The bending direction of the side brush curved arm 402 is turned from downward bending to horizontal bending, so that the ground clearance height of the side brush curved arm 402 can be lifted. And when the side brush assembly 4 is lifted to the highest position, the side brush bending portion 4021 abuts against the second abutting surface 2012. Wherein, a chamfer is also provided at a position of the second abutting surface 2012 far from the first abutting inclined surface 2011, and the chamfer is used to avoid the side brush assembly 4.

[0068] In some alternative embodiments, refer to Figure 12 As shown, the length of the second abutting surface 2012 on the guiding member 2 along the circumferential direction of the side brush transmission member 3 can also be extended, so that the relative rotation range between the side brush housing 1 and the side brush transmission member 3 can be further increased, which is convenient for controlling the lifting or lowering of the side brush assembly 4.

[0069] In an alternative embodiment of the utility model, refer to Figure 4As shown, the thickness of the side brush bending portion 4021 in the radial direction of the side brush transmission member 3 and away from the center of the side brush transmission member 3 is greater than the thickness near the center of the side brush transmission member 3.

[0070] In the embodiment of the present utility model, the thickness of the side brush bending portion 4021 refers to the thickness of the side brush bending portion 4021 in the axial direction of the side brush transmission member 3. Refer to Figure 3 and Figure 4 As shown, the central thickness of the side brush bending portion 4021 in the radial direction of the side brush transmission member 3 is set to be thinner. Thus, it is convenient for the guiding member 2 to apply a pressing force to the side brush bending portion 4021, so that the thinner area of the side brush bending portion 4021 can be bent downward to form the foldable feature on the side brush curved arm 402. And it can make the side brush curved arm 402 change the bending direction under the folding of the side brush bending portion 4021, thereby realizing the height lifting of the side brush curved arm 402.

[0071] In some embodiments, the thickness of the side brush bending portion 4021 in the radial direction of the side brush transmission member 3 and near the center of the side brush transmission member 3 is less than the thickness away from the center of the side brush transmission member 3, which can make the side brush bending portion 4021 form an arc groove or a V-shaped groove, etc. in the radial direction of the side brush transmission member 3. The side brush bending portion 4021 is in contact with the guiding member 2. Thus, it can make the side brush bending portion 4021 more easily pressed down, and make the central part with a thinner thickness on the side brush bending portion 4021 deformed, driving the side brush bending portion 4021 to fold downward, thereby changing the bending direction of the side brush curved arm 402.

[0072] In an alternative embodiment of the utility model, the side brush bending portion 4021 is made of rubber material.

[0073] In the embodiment of the present utility model, the side brush bending portion 4021 can be made of rubber material with good deformation performance, so that the side brush bending portion 4021 has good deformation performance and can maintain the structural stability of the side brush bending portion 4021 during repeated deformation, thereby improving the service life of the side brush bending portion 4021.

[0074] In an alternative embodiment of the utility model, refer to Figure 1 、 Figure 3 and Figure 4 As shown, the side brush assembly includes a side brush sleeving portion 401, the side brush sleeving portion 401 is sleeved on the side brush transmission member 3, and the side brush curved arm 402 is fixed to the side brush sleeving portion 401.

[0075] In an embodiment of the present utility model, the side brush sleeving part 401 may have an annular shape in the radial cross-section along the side brush transmission member 3, and it is sleeved on the side brush transmission member 3 to connect the side brush assembly 4 with the side brush transmission member 3. And through the side brush transmission member 3, a position limit of the side brush sleeving part 401 is formed along the axial direction of the side brush transmission member 3. Wherein, the side brush sleeving part 401 and the side brush bent arm 402 may be an integral structure.

[0076] In an alternative embodiment of the utility model, with reference to Figure 4 and Figure 6 As shown, a side brush limiting part 4011 is provided on the inner circumferential side of the side brush sleeving part 401, and a transmission limiting part 301 is provided on the side brush transmission member 3. Wherein, the side brush limiting part 4011 cooperates with the transmission limiting part 301 to form a limit on the side brush sleeving part 401 along the radial direction of the side brush transmission member 3.

[0077] In an embodiment of the present utility model, a side brush limiting part 4011 is provided on the inner circumferential side of the side brush sleeving part 401, and a transmission limiting part 301 is provided on the side brush transmission member 3. In some embodiments, the side brush limiting part 4011 may be a limiting groove, and the transmission limiting part 301 is a limiting protrusion that matches the shape of the limiting groove. In other embodiments, the side brush limiting part 4011 may be a limiting protrusion, and the transmission limiting part 301 may be a limiting groove that matches the shape of the limiting protrusion. Thus, when the side brush sleeving part 401 is sleeved on the side brush transmission member 3, through the cooperation of the side brush limiting part 4011 and the transmission limiting part 301, a limit on the side brush sleeving part 401 is formed along the radial direction of the side brush transmission member 3.

[0078] The side brush transmission member 3 may be a plastic part. After the side brush sleeving part 401 is sleeved on the side brush transmission member 3, the side brush transmission member 3 is injection-molded for the second time, so that a limit on the side brush sleeving part 401 can be formed along the axial direction of the side brush transmission member 3.

[0079] In some alternative embodiments, the number of the side brush bent arms 402 provided may be at least two, and at least two of the side brush bent arms 402 are equally angularly distributed about the central axis of the side brush sleeving part 401 in the horizontal circumferential direction of the side brush sleeving part 401. Those skilled in the art can determine the number of the side brush bent arms 402 according to actual design requirements, and no further limitation is made here. As a preferred embodiment, the number of the side brush bent arms 402 may be three.

[0080] In an alternative embodiment of the utility model, with reference to Figure 1 、 Figure 2 and Figure 10As shown, the side brush assembly 4 further includes a side brush hair bundle 403 located at the end of the side brush curved arm 402 away from the side brush sleeving portion 401. Wherein, the side brush curved arm 402 is folded under the abutment of the guide member 2 to raise or lower the height of the side brush hair bundle 403.

[0081] In an embodiment of the present utility model, the side brush assembly 4 may further include a side brush hair bundle 403, and the side brush hair bundle 403 is located at the end of the side brush curved arm 402 away from the side brush sleeving portion 401 (which can also be understood as being located at the rear end of the curved arm). The side brush hair bundle 403 is mainly used for floor cleaning. Thus, through the rotation of the side brush transmission member 3 or the rotation of the side brush housing 1, the side brush hair bundle 403 located on the side brush curved arm 402 can be driven to rotate synchronously, thereby realizing the floor cleaning of the side brush hair bundle 403. In some embodiments, the side brush hair bundle 403 can also be made of materials such as rubber and plastic.

[0082] The abutting force generated by the guide member 2 on the side brush curved arm 402 raises the ground clearance height of the side brush hair bundle 403 when the side brush curved arm 402 is folded downward. Thus, when the cleaning robot is cleaning liquid dirt or in a single mopping mode, the side brush hair bundle 403 can be kept away from the ground through the folding manner of the side brush assembly 4, avoiding the side brush hair bundle 403 from contacting the dirt, improving the cleanliness of the side brush device and avoiding secondary pollution during the process of cleaning the ground.

[0083] In an alternative embodiment of the utility model, with reference to Figure 2 、 Figure 5 and Figure 7 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 accommodation cavity 1001.

[0084] 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, and thus through the up-and-down assembly of the first housing 101 and the second housing 102, the accommodation cavity 1001 is formed. 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, positioning structures and through holes for assembling the side brush curved arm 402 can also be provided on the end faces of the first housing 101 and the second housing 102 that are close to each other.

[0085] In another alternative embodiment, the side brush housing 1 may include a first housing 101 and a second housing 102 located on the left side of the first housing 101, and the first housing 101 and the second housing 102 cooperate to form the accommodation cavity 1001.

[0086] In the embodiment of the present utility model, the side brush housing 1 may further include a first housing 101 and a second housing 102. Among them, the second housing 102 is located on the left side of the first housing 101, so that through the left-right assembly of the first housing 101 and the second housing 102, the accommodation cavity 1001 is formed. In some embodiments, the first housing 101 and the second housing 102 may be connected by means such as welding, bonding, and clamping. No further limitation is made here. For example, a positioning structure and a through hole for assembling the side brush curved arm 402 may also be provided on the mutually approaching end faces of the first housing 101 and the second housing 102.

[0087] In an alternative embodiment of the utility model, the side brush device further includes an elastic member 5 sleeved on the side brush transmission member 3. The first end of the elastic member 5 is fixed to the side brush housing 1, and the second end of the elastic member 5 is fixed to the side brush transmission member 3, so as to drive the folding and resetting of the side brush curved arm 402 through the deformation recovery of the elastic member 5. Among them, when the side brush housing 1 drives the side brush assembly 4 to rotate, the elastic member 5 provides a torsional force to keep the guide member 2 in contact with the side brush assembly 4. When the side brush housing 1 and the side brush assembly 4 move relative to each other, the torsional force of the elastic member 5 increases, and through the torsional recovery of the elastic member 5, the side brush assembly 4 is driven to fold and reset.

[0088] In the embodiment of the present utility model, the elastic member 5 is sleeved on the side brush transmission member 3, and its two ends are respectively fixed to the side brush transmission member 3 and the side brush housing. For example, referring to Figure 1 As shown, the elastic member 5 may include a torsion spring. The first end of the elastic member 5 is fixed to the first housing 101, and the second end of the elastic member 5 is fixed to the side brush transmission member 3. Thus, an elastic connection between the side brush transmission member 3 and the first housing 101 can be formed through the elastic member 5 along the circumferential direction of the side brush transmission member 3.

[0089] In some other embodiments, referring to Figure 11 As shown, the first end of the elastic member 5 is fixed to the second housing 102, and the second end of the elastic member 5 is fixed to the side brush transmission member 3, so that an elastic connection between the side brush transmission member 3 and the second housing 102 can be formed through the elastic member 5 along the circumferential direction of the side brush transmission member.

[0090] When the guide member 2 abuts against the side brush crank arm 402 and drives the side brush crank arm 402 to rotate synchronously, when the side brush assembly 4 is in the descending state, the elastic deformation torsion force of the elastic member 5 is used to maintain the abutment between the guide member 2 and the side brush crank arm 402. Thus, the side brush assembly 4 can be kept in contact with the ground, and the ground can be cleaned by the rotation of the side brush assembly 4.

[0091] When the side brush housing 1 rotates relative to the side brush transmission member 3 under the action of an external force, the elastic potential energy (which can also be called the deformation torsion force) of the elastic member 5 increases, so that the abutting force of the guide member 2 on the side brush crank arm 402 increases, and the guide member 2 presses down the side brush crank arm 402 to cause the side brush crank arm 402 to fold downward.

[0092] When the side brush housing 1 drives the side brush transmission member 3 to rotate synchronously again, under the torsional recovery action of the elastic member 5, the side brush bending portion 4021 moves along the abutting inclined surface 201, and the abutting force of the abutting inclined surface 201 on the side brush bending portion 4021 gradually decreases, so that the deformation of the side brush bending portion 4021 is restored. The bending direction of the side brush crank arm 402 is reset to the state of being horizontally downward. And the elastic deformation torsion force of the elastic member 5 is used to maintain the abutment between the guide member 2 and the side brush crank arm 402. Thus, the side brush assembly 4 can be kept in contact with the ground, and the ground can be cleaned by the rotation of the side brush assembly 4.

[0093] An optional embodiment of the utility model, referring to Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, a first clamping groove 1002 is formed on the first housing 101, and the first end of the elastic member 5 is clamped in the first clamping groove 1002 along the radial direction of the side brush transmission member 3. Wherein, a second clamping groove 3002 is formed on the side brush transmission member 3, and the second end of the elastic member 5 is clamped in the second clamping groove 3002.

[0094] In the embodiment of the present utility model, a first clamping groove 1002 is provided on the first housing 101, or a first clamping groove 1002 is provided on the second housing 102. A second clamping groove 3002 is provided on the side brush transmission member 3, and the first clamping groove 1002 and the second clamping groove 3002 are used for clamping and assembling the elastic member 5. For example, the first end of the elastic member 5 is clamped in the first clamping groove 1002 along the radial direction of the side brush transmission member 3. The second end of the elastic member 5 is clamped in the second clamping groove 3002. Thus, when the elastic member 5 is sleeved on the side brush transmission member 3, the elastic member 5 can be fixed through the cooperation of the first clamping groove 1002 and the second clamping groove 3002, and it can be ensured that when there is no relative movement between the guide member 2 and the side brush assembly 4, the elastic member 5 has a small torsional force, so that the guide member 2 and the side brush assembly 4 remain in abutment.

[0095] Referring to Figure 11 As shown, as a preferred embodiment, the elastic member 5 is arranged between the second housing 102 and the side brush assembly 4, which can effectively reduce the axial length of the side brush transmission member 3 and the axial length of the elastic member 5.

[0096] In an alternative embodiment of the present utility model, referring to Figure 10 As shown, a threaded through hole 3001 is provided in the vertical direction of the side brush transmission member 3. The side brush device may further include a threaded connector 6 and a transmission shaft 7. The threaded connector 6 is threadedly connected to the side brush transmission member 3 through the threaded through hole 3001. The transmission shaft 7 is coaxially arranged with the side brush transmission member 3, and the transmission shaft 7 is connected to the threaded connector 6 to drive the side brush transmission member 3 to rotate through the transmission shaft 7.

[0097] In the embodiment of the present utility model, the transmission shaft 7 is coaxially fixed to the side brush transmission member 3, and it is used to drive the side brush transmission member 3 to rotate. The threaded connector 6 penetrates through the central axis of the side brush transmission member 3. On the one hand, the threaded connector 6 serves as the rotation axis of the side brush transmission member 3. On the other hand, the threaded connector 6 is used for fixed connection with the transmission shaft 7 and also serves as a power input component.

[0098] The threaded through hole 3001 and the threaded connection hole are coaxially arranged, that is, the central axis of the threaded through hole 3001 coincides with the central axis of the threaded connection hole. In order to facilitate improving the connection stability between the transmission shaft 7 and the side brush transmission member 3, the threaded connector 6 can penetrate through the side brush transmission member 3 completely from the bottom of the side brush transmission member 3 and be threadedly connected to the threaded connection hole, so as to realize the fixed connection between the transmission shaft 7 and the side brush transmission member 3.

[0099] In the embodiment of the present utility model, in order to facilitate the installation of the threaded connecting member 6, relevant holes may be opened in the corresponding assembly areas of the first housing 101 and / or the second housing 102. For example, an assembly through hole 1021 may be opened on the central axis of the second housing 102, etc., and no further limitation is made here. The threaded connecting member 6 may be a connecting member such as a screw or a bolt.

[0100] In an alternative embodiment of the utility model, with reference to Figure 10 As shown, the side brush device may further include a second gear 8 and a one-way transmission member 9. The second gear 8 is sleeved on the transmission shaft 7 and is movably connected to the transmission shaft 7. Among them, the second gear 8 is coaxially fixed to the first housing 101 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. Among them, when the second gear 8 rotates forward, it drives the side brush housing 1 to rotate, and the guide member 2 abuts against the side brush curved arm 402 and drives the side brush transmission member 3 to rotate. When the second gear 8 rotates reversely, it drives the side brush housing 1 to rotate. Under the abutting force of the guide member 2 and the locking force of the one-way transmission member 9 on the side brush transmission member 3, the guide member 2 presses down on the side brush curved arm 402 to form a fold.

[0101] In the embodiment of the present utility model, the movable connection between the second gear 8 and the transmission shaft 7 means that the rotation of the second gear 8 does not directly drive the rotation of the transmission shaft 7. For example, the movable connection may be a clearance fit, a sliding connection, etc. Thus, under the action of an external force on the second gear 8, 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 and restricts the side brush transmission member 3 to rotate only in one rotation direction. For example, the rotating part of the one-way transmission member 9 is fixed to the transmission shaft 7. When the transmission shaft 7 rotates forward under force, the one-way transmission member 9 does not restrict the rotation of the transmission shaft 7. When the transmission shaft 7 rotates reversely under force, due to the one-way locking function of the one-way transmission member 9, the current position of the transmission shaft 7 is locked, and the transmission shaft 7 cannot rotate reversely.

[0102] The coaxial fixation of the second gear 8 and the side brush housing 1 means that the central axis of the second gear 8 coincides with the central axis of the side brush housing 1, and the second gear 8 is fixed to the side brush housing 1. When the second gear 8 rotates forward, the side brush housing 1 coaxially fixed with the second gear 8 rotates forward synchronously with the second gear 8. At this time, the guide member 2 on the side brush housing 1 abuts against the side brush crank arm 402, and drives the side brush transmission member 3 to rotate synchronously by the abutting force exerted on the side brush crank arm 402 by the guide member 2. Among them, when the transmission shaft 7 rotates forward under force, the one-way transmission member 9 does not restrict the rotation of the transmission shaft 7, so that the rotation of the side brush assembly 4 can be realized. At this time, the side brush assembly 4 is in a lowered state. Therefore, when the second gear 8 rotates forward, it can drive the side brush assembly 4 to rotate in the lowered state, so that the side brush assembly 4 remains in contact with the ground and performs normal ground cleaning.

[0103] When the second gear 8 rotates reversely, the side brush housing 1 rotates reversely synchronously. Due to the locking effect of the one-way transmission member 9 on the side brush transmission member 3, the side brush transmission member 3 cannot rotate synchronously with the side brush housing 1. At this time, the side brush crank arm 402 fixed to the side brush transmission member 3 rotates relative to the side brush housing 1. Therefore, during the relative rotation, the abutting force pressing down on the side brush bending portion 4021 is increased through the abutting inclined surface 201 of the guide member 2, so that the side brush bending portion 4021 is turned downward under the action of the abutting force. And the height of the side brush bristles 403 from the ground is lifted. At this time, the deformation torsional force of the elastic member 5 increases.

[0104] In the case of the next forward rotation of the second gear 8, due to the torsional recovery of the elastic member 5, after the abutting inclined surface 201 gradually reduces the abutting force with the side brush crank arm 402, the side brush bending portion 4021 deforms and recovers to turn upward, and moreover, the side brush crank arm 402 is reset from the lifted state to the lowered state. Finally, the guide member 2 abuts against the side brush bending portion 4021 with a smaller abutting force. Thus, when the second gear 8 rotates forward and the side brush housing 1 drives the side brush transmission member 3 to rotate synchronously again, the side brush assembly 4 repeats the ground cleaning work. When the cleaning robot sweeps liquid dirt or is in the single mopping mode, the side brush assembly 4 can be turned over so that the side brush assembly 4 is away from the ground, avoiding contact between the side brush assembly 4 and the dirt, improving the cleanliness of the side brush device and avoiding secondary pollution during the ground cleaning process.

[0105] In an optional embodiment of the utility model, the second gear 8 is fixedly connected to the side brush housing 1 by clamping.

[0106] When a fixed connection is formed between the threaded connector 6 and the transmission shaft 7 by means of threads or other methods, the second gear 8 can be fixedly connected to the side brush housing 1 in a snap-fit manner. For example, a first snap-fit portion is provided on the first housing 101, and a second snap-fit portion that is shape-matching with the first snap-fit portion is provided on the end face of the second gear 8 close to the side brush housing 1. Among them, the radial cross-section of the first snap-fit portion along the side brush transmission member 3 is an irregular shape, so that when the first snap-fit portion and the second snap-fit portion are shape-matching, the radial displacement of the side brush housing 1 along the side brush transmission member 3 can be defined, so that the side brush housing 1 can be driven to rotate synchronously by the second gear 8. And at the same time, the convenience of disassembly and assembly between the second gear 8 and the side brush housing 1 is improved.

[0107] In an alternative embodiment of the utility model, with reference to Figure 10 As shown, the side brush device further includes a gear box 10 and a rotary motion output device 11. The second gear 8 and the one-way transmission member 9 are both installed in the gear box 10. The rotary motion output device 11 is in transmission connection with the second gear 8 to drive the side brush housing 1 to rotate through the rotary motion output device 11.

[0108] In the embodiment of the present utility model, the gear box 10 is used to provide an assembly space for the one-way transmission member 9 and the second gear 8. The second gear 8 and the one-way transmission member 9 are respectively installed in the gear box 10. In another embodiment, the rotary motion output device 11 can also be installed on the gear box 10. The rotary motion output device 11 is used to output rotary motion, and it is in transmission connection with the second gear 8, so that the second gear 8 can be driven to rotate through the rotary motion output device 11, and rotational power is provided for the side brush housing 1. The rotary motion output device 11 can include devices such as a servo motor and a stepper motor.

[0109] When the second gear 8 is coaxially fixed to the first housing 101 and the one-way transmission member 9 is fixed to the transmission shaft 7, when the rotary motion outputter 11 rotates forward, it drives the second gear 8 connected to the rotary motion outputter 11 to rotate forward, and drives the side brush housing 1 to rotate forward synchronously. At this time, the guide member 2 on the side brush housing 1 abuts against the side brush crank 402, and drives the side brush transmission member 3 to rotate synchronously by the abutting force applied to the side brush crank 402 by the guide member 2. When the transmission shaft 7 is forced to rotate forward, the one-way transmission member 9 does not restrict the rotation of the transmission shaft 7. Thus, the rotation of the side brush assembly 4 can be realized. And, at this time, the side brush assembly 4 is in the descending state. Thus, when the second gear 8 rotates forward, it can drive the side brush assembly 4 to rotate in the descending state, so that the side brush assembly 4 remains in contact with the ground and performs normal ground cleaning.

[0110] When the rotary motion outputter 11 rotates reversely, it drives the second gear 8 connected to the rotary motion outputter 11 to rotate reversely, and the side brush housing 1 rotates reversely synchronously. Due to the locking effect of the one-way transmission member 9 on the side brush transmission member 3, the side brush transmission member 3 cannot rotate synchronously with the side brush housing 1. At this time, the side brush crank 402 fixed to the side brush transmission member 3 rotates relative to the side brush housing 1. Thus, during the relative rotation process, the abutting force pressing the side brush crank 402 downward is increased through the abutting inclined surface 201 of the guide member 2, so that the side brush crank 402 is folded downward under the action of the abutting force. And the height of the side brush bristles 403 from the ground is lifted. At this time, the elastic member 5 is deformed and twisted.

[0111] And when the side brush assembly 4 is lifted to the highest position, the rotary motion outputter 11 stops rotating. Among them, the rotary motion outputter 11 controls the relative rotation angle between the side brush assembly 4 and the side brush transmission member 3 within 120° (including 120° itself). When the rotary motion outputter 11 rotates forward next time and drives the second gear 8 to rotate forward, under the action of the torsional recovery of the elastic member 5, the side brush bending portion 4021 moves along the abutting inclined surface 201, and the abutting force of the abutting inclined surface 201 on the side brush bending portion 4021 gradually decreases, so that the deformation of the side brush bending portion 4021 is restored. The bending direction of the side brush crank 402 is reset to the state of horizontally downward. And through the deformation and torsional force of the elastic member 5, the abutting of the guide member 2 and the side brush crank 402 is maintained. Thus, the side brush assembly 4 can be kept in contact with the ground, and the ground can be cleaned by the rotation of the side brush assembly 4.

[0112] Other transmission structures can be adopted for power transmission between the rotational motion outputter 11 and the second gear 8. For example, the side brush device may further include a gear set 12, and the gear set 12 may include at least one driving gear, so that the gear set 12 meshes with the second gear 8, and the output shaft of the rotational motion outputter 11 is coaxially fixed to the driving gear for power input in the gear set 12.

[0113] In summary, the embodiment of the present utility model discloses a side brush device, which may include a side brush housing 1, a guide member 2, a side brush transmission member 3, and a side brush assembly 4. A receiving cavity 1001 is provided in the side brush housing 1, the guide member 2 is located in the receiving cavity 1001 and fixed to the side brush housing 1. The side brush transmission member 3 is vertically installed in the receiving cavity 1001. The side brush assembly 4 penetrates through the side brush housing 1 and is sleeved on the side brush transmission member 3. Wherein, the side brush assembly 4 abuts against the guide member 2 and is driven to fold by the abutting force. Thus, when the cleaning robot cleans liquid dirt or is in the single mopping mode, the side brush assembly 4 can be folded to be away from the ground, avoiding the side brush assembly 4 from contacting the dirt, improving the cleanliness of the side brush device, and avoiding secondary pollution during the process of cleaning the ground.

[0114] The embodiment of the present utility model also discloses a cleaning robot, which may include the side brush device as described in any one of the above-mentioned utility model embodiments.

[0115] The embodiment of the present utility model also discloses a cleaning robot, which may include a side brush housing 1, a guide member 2, a side brush transmission member 3, and a side brush assembly 4. A receiving cavity 1001 is provided in the side brush housing 1, the guide member 2 is located in the receiving cavity 1001 and fixed to the side brush housing 1. The side brush transmission member 3 is vertically installed in the receiving cavity 1001. The side brush assembly 4 penetrates through the side brush housing 1 and is sleeved on the side brush transmission member 3. Wherein, the side brush assembly 4 abuts against the guide member 2 and is driven to fold by the abutting force. Thus, when the cleaning robot cleans liquid dirt or is in the single mopping mode, the side brush assembly 4 can be folded to be away from the ground, avoiding the side brush assembly 4 from contacting the dirt, improving the cleanliness of the side brush device, and avoiding secondary pollution during the process of cleaning the ground.

[0116] In summary, the embodiments of the present utility model also disclose a side brush device and a cleaning robot. The embodiments of the present utility model may include a side brush housing 1, a guide member 2, a side brush transmission member 3, and a side brush assembly 4. A receiving cavity 1001 is provided in the side brush housing 1. The guide member 2 is located in the receiving cavity 1001 and fixed to the side brush housing 1. The side brush transmission member 3 is vertically installed in the receiving cavity 1001. The side brush assembly 4 penetrates through the side brush housing 1 and is sleeved on the side brush transmission member 3. Among them, the side brush assembly 4 abuts against the guide member 2 and drives the side brush assembly 4 to fold through the abutting force.

[0117] During the operation of the cleaning robot, if the second gear 8 rotates forward, the side brush housing 1 fixed coaxially with the second gear 8 rotates forward synchronously with the second gear 8. At this time, the guide member 2 on the side brush housing 1 abuts against the side brush arm 402, and drives the side brush transmission member 3 to rotate synchronously through the abutting force applied by the guide member 2 to the side brush arm 402. Among them, when the transmission shaft 7 is forced to rotate forward, the one-way transmission member 9 does not restrict the rotation of the transmission shaft 7, so that the rotation of the side brush assembly 4 can be realized. At this time, the side brush assembly 4 is in a descending state. Therefore, when the second gear 8 rotates forward, it can drive the side brush assembly 4 to rotate in the descending state, so that the side brush assembly 4 remains in contact with the ground and performs normal ground cleaning.

[0118] In the case where the second gear 8 rotates reversely, the side brush housing 1 rotates reversely synchronously. Due to the locking effect of the one-way transmission member 9 on the side brush transmission member 3, the side brush transmission member 3 cannot rotate synchronously with the side brush housing 1. At this time, the side brush arm 402 fixed to the side brush transmission member 3 rotates relative to the side brush housing 1. Thus, during the relative rotation, the abutting force pressing the side brush arm 402 downward is increased through the abutting inclined surface 201 of the guide member 2, so that the side brush arm 402 folds downward under the action of the abutting force. And the height of the side brush bundle 403 from the ground is lifted. At this time, the elastic member 5 is deformed and twisted.

[0119] In the case where the second gear 8 rotates forward next time, under the action of the torsional recovery of the elastic member 5, the side brush bending portion 4021 moves along the abutting inclined surface 201, and the abutting force of the abutting inclined surface 201 on the side brush bending portion 4021 gradually decreases, so that the deformation of the side brush bending portion 4021 is restored. The bending direction of the side brush curved arm 402 is reset to a state of horizontally downward. And through the deformation and torsional force of the elastic member 5, the abutting connection between the guide member 2 and the side brush curved arm 402 is maintained, whereby the side brush assembly 4 can be kept in contact with the ground, and the ground can be cleaned by the rotation of the side brush assembly 4. Thus, when the cleaning robot cleans liquid dirt or is in a single mopping mode, the side brush assembly 4 can be folded away from the ground, avoiding contact between the side brush assembly 4 and dirt, improving the cleanliness of the side brush device and preventing secondary pollution during the process of cleaning the ground.
