The sweeping machine may specifically include: a housing 10, a side brush structure 30, a cleaning unit 20 and a locking structure;

[0054] The side brush structure 30 is rotatably connected to the bottom of the housing 10, and the cleaning portion 20 is spaced apart from the side brush structure 30;

[0055] The locking structure is disposed in the housing 10 , and the locking structure is connected to the side brush structure 30 ;

[0056] The side brush structure 30 has a plurality of extended brush strips 31 , and the locking structure can lock the side brush structure 30 so that at least one of the brush strips 31 is located in the cleaning portion 20 to clean the brush strip 31 .

[0057] In the embodiment of the present application, the side brush structure 30 is positioned by the locking structure, so that the brush strip 31 used for cleaning by the side brush structure 30 is located in the cleaning part 20, and the hair, pet hair, rope and other easily generated garbage on the brush strip 31 are cleaned by the cleaning part 20, so that the side brush structure 30 has better cleaning performance, reducing the hidden dangers of causing motor stalling or even device damage. When the side brush structure 30 does not need to be cleaned, the locking structure can unlock the side brush structure 30, so that the side brush structure 30 can work normally to clean the floor.

[0058] In the embodiments of the present application, Figure 2 As shown in FIG. 1 , the brush strip 31 is located in the cleaning portion 20. At this time, the cleaning portion 20 performs self-cleaning on the brush strip 31. Figure 3 As shown in FIG. 1 , it is a schematic diagram of the brush strip 31 not being located in the cleaning portion 20. At this time, the cleaning portion 20 does not perform self-cleaning on the brush strip 31. Figure 4 As shown, hair, ropes and other debris are easily entangled on the side brush structure 30. Figure 5 As shown, the arrow indicates the cleaning direction of the cleaning part 20 for hair, rope and other debris. The cleaning part 20 can clean the hair, rope and other debris along the direction of the arrow to the brush bar 31. Figure 6 As shown, the arrow also indicates the cleaning direction of the cleaning part 20 for hair, rope and other debris. At this time, the cleaning part 20 cleans the hair, rope and other debris from the brush bar 31 along the direction of the arrow, thereby achieving a better self-cleaning function for the brush bar 31.

[0059] For example, in the embodiment of the present application, the cleaning part 20 may be provided with a roller brush, and the roller brush is used to roll and clean the hair, pet hair, rope and other garbage that is easy to entangle on the brush bar 31. In addition, the cleaning part 20 may also be provided with a dust suction structure, and the hair, pet hair, rope and other garbage on the brush bar 31 are sucked and cleaned by the dust suction structure. The specific type of the cleaning part 20 is not limited in the embodiment of the present application.

[0060] In the embodiment of the present application, the side brush structure 30 is rotatably connected to the shell 10, and the brush strip 31 is in contact with the ground. The brush strip 31 cleans the ground through the rotation of the side brush structure 30. For example, the side brush structure 30 can be arranged at the edge of the bottom of the shell 10, and further, the side brush structure 30 can also be arranged at the middle position of the bottom of the shell 10. Similarly, the cleaning part 20 can be arranged at the middle position of the bottom of the shell 10, and further, the side brush structure 30 can also be arranged at the edge of the bottom of the shell 10, and so on. The embodiment of the present application does not limit the specific arrangement positions of the side brush structure 30 and the cleaning part 20.

[0061] For example, in the embodiment of the present application, the side brush structure 30 has a plurality of brush strips 31, such as two, three, five or ten, etc., which can be set according to actual needs, and the embodiment of the present application may not limit the specific number and setting method of the brush strips 31. The locking structure locks the side brush structure 30, so that one of the brush strips 31 can be located in the cleaning part 20, two of the brush strips 31 can be located in the cleaning part 20, three of the brush strips 31 can be located in the cleaning part 20, etc., and can be set according to the setting range and cleaning requirements of the cleaning part 20, etc., and the embodiment of the present application may not limit this.

[0062] In the embodiment of the present application, for example, the number of the side brush structures 30 can be one, two, or three, etc., the number of the cleaning parts 20 can be set to one, and multiple side brush structures 30 can be distributed at intervals on the edge of the housing 10 with the cleaning part 20 as the center, so that one cleaning part 20 can clean the brush strips 31 of multiple side brush structures 30 at the same time. In addition, the number of the cleaning parts 20 can also be set to two or three, etc., one side brush structure 30 can be set corresponding to one cleaning part 20, or two side brush structures 30 can share one cleaning part 20. The embodiment of the present application does not limit the specific number and setting method of the cleaning parts 20 and the side brush structures 30.

[0063] Specifically, in the embodiment of the present application, the housing 10 is used to provide a space for the locking structure, and to connect the side brush structure 30 and to set the cleaning part 20. For example, the material of the housing 10 can be plastic, or metal, etc. The embodiment of the present application does not limit the specific material and shape of the housing 10.

[0064] Optionally, in the embodiment of the present application, the locking structure includes the first transmission assembly and the locking member 43; the first transmission assembly is connected to the side brush structure 30, the locking member 43 is connected to the first transmission assembly, and the locking member 43 locks the movement of the first transmission assembly, driving the first transmission assembly to lock the side brush structure 30. In this way, the connection and transmission between the side brush structure 30 and the locking structure are realized by the first transmission assembly, and the locking member 43 locks the first transmission assembly to realize the locking of the rotational movement of the side brush structure 30, so that it stops rotating, so that the brush strip 31 is in the cleaning part 20 for cleaning, and the self-cleaning function of the sweeper on the side brush structure 30 is realized.

[0065] In the embodiment of the present application, optionally, the first transmission assembly includes a first transmission member 41 and a second transmission member 42, the first transmission member 41 is connected to the side brush structure 30, the second transmission member 42 is connected to the first transmission member 41, and the locking member 43 is connected to the second transmission member 42. In this way, the first transmission assembly is connected to the side brush structure 30 through the first transmission member 41, and the first transmission assembly is connected to the locking member 43 through the second transmission member 42, which has a better transmission effect and is also convenient for setting according to the spatial layout in the housing 10.

[0066] For example, the number of the first transmission members 41 can be one or two, or three, etc., and can be set according to the space volume and transmission and layout requirements of the housing 10 according to actual needs. The specific number of the first transmission members 41 is not limited in the embodiment of the present application. Similarly, the number of the second transmission members 42 can be two or two, or three, etc., and can be set according to the space volume and transmission and layout requirements of the housing 10 according to actual needs. The specific number of the second transmission members 42 is not limited in the embodiment of the present application.

[0067] Optionally, in the embodiment of the present application, the first transmission member 41 is an incomplete gear, the second transmission member 42 is a transmission gear, and the locking member 43 is a one-way bearing; the incomplete gear is connected to the side brush structure 30, the transmission gear is meshed with the incomplete gear, and the one-way bearing is connected to the transmission gear; the side brush structure 30 rotates in a first direction, driving the incomplete gear to rotate, the incomplete gear drives the transmission gear to rotate, and the transmission gear drives the one-way bearing to rotate in the first direction; the side brush structure 30 rotates in a second direction, driving the incomplete gear to rotate, the incomplete gear drives the transmission gear to rotate in the second direction, and the one-way bearing locks the transmission gear, wherein the second direction is opposite to the first direction. In this way, the locking position of the side brush structure 30 is limited by the meshing position of the incomplete gear and the transmission gear, so that the brush strip 31 is located at the cleaning portion 20, and the rotation of the transmission gear is locked by the locking member 43, thereby locking the brush strip 31 of the side brush structure 30.

[0068] Specifically, in the embodiment of the present application, the incomplete gear may also be called a sector gear, which is a gear with partial gear teeth, that is, the number of its teeth is incomplete. When the gear teeth of the incomplete gear mesh with the transmission gear, the incomplete gear drives the transmission gear to rotate. The incomplete gear and the transmission gear are combined to form an incomplete gear mechanism, and the incomplete gear drives the transmission gear to rotate intermittently. Figure 7 As shown, the incomplete gear is provided with two gear teeth. In addition, the incomplete gear can also be provided with three gear teeth or four gear teeth, etc., which can be set according to actual needs. The embodiment of the present application may not limit the specific number of gear teeth of the incomplete gear.

[0069] For example, in the embodiment of the present application, when the side brush structure 30 works normally without self-cleaning, the side brush structure 30 rotates in the clockwise direction, driving the incomplete gear to rotate in the clockwise direction, the incomplete gear drives the transmission gear to rotate intermittently in the clockwise direction, and the transmission gear drives the one-way bearing to rotate in the clockwise direction. When the side brush structure 30 needs to make the brush strip 31 located in the cleaning part 20 for self-cleaning, the side brush structure 30 rotates in the counterclockwise direction, driving the incomplete gear to rotate in the counterclockwise direction, the incomplete gear drives the transmission gear to rotate in the counterclockwise direction, the transmission gear drives the one-way bearing to have a tendency to rotate in the counterclockwise direction, and the one-way bearing can only rotate in the clockwise direction and cannot rotate in the counterclockwise direction, thereby realizing the locking of the transmission gear and the incomplete gear in the counterclockwise direction, so that the brush strip 31 of the side brush structure 30 stops rotating when located in the cleaning part 20, and the self-cleaning function of the brush strip 31 of the cleaning part 20 is realized.

[0070] In the embodiment of the present application, the position of the gear teeth of the incomplete gear can be designed according to the setting position of the brush strip 31. When the incomplete gear rotates counterclockwise, through the locking effect of the one-way bearing, when the incomplete gear is in a position where the rotation stops, the brush strip 31 is located in the area of ​​the cleaning portion 20. The specific structural type such as the position and number of the gear teeth of the incomplete gear can be set according to actual needs, and the embodiment of the present application is not limited to this.

[0071] In the embodiment of the present application, for example, the one-way bearing can rotate in a first direction, such as clockwise, and cannot rotate in the opposite direction, such as counterclockwise, to achieve locking. In addition, the one-way bearing can also rotate in the counterclockwise direction, and cannot rotate in the clockwise direction to achieve locking. The embodiment of the present application does not limit the rotatable direction of the one-way bearing.

[0072] Optionally, in the embodiment of the present application, the sweeper further includes a driver 50 and a second transmission assembly connected to the driver 50; the second transmission assembly is disposed in the housing 10, and the second transmission assembly is connected to the side brush structure 30, and the driver 50 drives the second transmission assembly to rotate in a first direction or a second direction, and the second direction is opposite to the first direction. The side brush structure 30 is also connected to the locking structure, so that a relatively stable and reliable driving force is provided by the driver 50, and when the side brush structure 30 performs a cleaning operation on the ground, the driver 50 outputs a driving force rotating in the first direction, drives the second transmission assembly to move, and drives the side brush structure 30 to rotate in the first direction to clean the ground. At this time, the one-way bearing of the locking structure can rotate in the first direction without locking the side brush structure 30, so as to avoid affecting the side brush structure 30 when performing a ground cleaning operation. When the side brush structure 30 performs self-cleaning on its brush strip 31, the driver 50 outputs a driving force rotating in the second direction, drives the second transmission assembly to move, and the second transmission assembly drives the side brush structure 30 to rotate in the second direction. At this time, the locking structure locks the rotation of the side brush structure 30 through the one-way bearing and the first transmission assembly. Specifically, the side brush body 33 of the side brush structure 30 stops rotating, and the position of the brush strip 31 is locked.

[0073] For example, in an embodiment of the present application, the driver 50 may be an electric motor or the like, and the output end of the driver 50 is connected to the second transmission component for driving the second transmission component to rotate. The embodiment of the present application may not limit the specific type of the driver 50.

[0074] In the embodiment of the present application, optionally, the side brush structure 30 includes a side brush shell 32 and a side brush body 33, the side brush body 33 is provided with a plurality of brush strips 31, and the brush strips 31 extend out of the side brush shell 32; the side brush body 33 is rotatably connected to the side brush shell 32, the second transmission assembly is connected to the side brush shell 32, and the first transmission member 41 is connected to the side brush body 33. In this way, the second transmission assembly can drive the side brush shell 32 to rotate, and when the side brush structure 30 is reversed, the first transmission assembly can lock the rotation of the side brush body 33 to prevent the side brush structure 30 from being damaged by the locking effect of the locking structure.

[0075] For example, in the embodiment of the present application, when the driver 50 drives the second transmission assembly to rotate in the first direction, the second transmission assembly drives the side brush housing 32 to rotate in the first direction, and the side brush housing 32 can drive the side brush body 33 to rotate in the first direction, so that the brush strip 31 on the side brush body 33 rotates to clean the ground. When the driver 50 drives the second transmission assembly to rotate in the second direction opposite to the first direction, the second transmission assembly drives the side brush housing 32 to rotate in the second direction, the side brush housing 32 drives the side brush body 33 to rotate in the second direction, and the side brush body 33 drives the first transmission assembly to rotate in the second direction, and the locking member 43 counter-bearing locks the rotation of the first transmission assembly in the second direction, so that at least one brush strip 31 is located in the cleaning portion 20, and at the same time, the side brush housing 32 rotates relative to the side brush body 33 under the action of the second transmission assembly.

[0076] In the embodiment of the present application, for example, the side of the side brush housing 32 is provided with an opening, and the side brush curved arm 35 of the side brush body 33 extends out of the side brush housing 32 from the opening. For example, the side brush housing 32 may include an upper housing and a lower housing, and the upper housing and the lower housing are enclosed to form a receiving cavity, and the central part of the side brush body 33 is located in the receiving cavity, which facilitates assembly and improves assembly efficiency. In addition, the side brush housing 32 may also be an integrally formed structure or a plurality of split structures, and the embodiment of the present application may not limit the specific type of the side brush housing 32.

[0077] Optionally, in the embodiment of the present application, the second transmission assembly includes a first gear 61, a second gear 62 and a third gear 63; the first gear 61 is connected to the driver 50, the second gear 62 is meshed with the first gear 61, the third gear 63 is meshed with the second gear 62, and the side brush structure 30 is connected to the third gear 63. Specifically, the side brush shell 32 of the side brush structure 30 is connected to the third gear 63, so that the connection between the second transmission assembly and the driver 50 is realized through the first gear 61, the connection between the second transmission assembly and the side brush structure 30 is realized through the third gear 63, and the transmission between the first gear 61 and the third gear 63 is realized through the second gear 62, which has good transmission efficiency and transmission reliability, and is convenient for designing the force transmission path according to the spatial layout in the housing 10.

[0078] For example, in the embodiment of the present application, the second gear 62 includes a first gear ring and a second gear ring arranged at intervals, the first gear ring is meshed with the first gear 61, and the second gear ring is meshed with the third gear 63, so that the second gear 62 is respectively meshed with the first gear 61 and the third gear 63. In addition, the same gear ring of the second gear 62 can also be meshed with the first gear 61 and the third gear 63, respectively. The embodiment of the present application does not limit the specific type of the second gear 62.

[0079] In the embodiment of the present application, for example, the number of the first gears 61 can be one or two, or three, etc., and can be set according to the spatial volume, transmission, and layout requirements of the shell 10 according to actual needs. The specific number of the first gears 61 set in the embodiment of the present application may not be limited. Similarly, the number of the second gears 62 can be two or two, or three, etc., and can be set according to the spatial volume, transmission, and layout requirements of the shell 10 according to actual needs. The specific number of the second gears 62 set in the embodiment of the present application may not be limited. And, the number of the third gears 63 can be three or two, or three, etc., and can be set according to the spatial volume, transmission, and layout requirements of the shell 10 according to actual needs. The specific number of the third gears 63 set in the embodiment of the present application may not be limited.

[0080] Optionally, in the embodiment of the present application, the locking structure and the second transmission assembly are at least partially coaxially arranged. In this way, the locking structure and the second transmission assembly can be arranged on the same axis, which can save the additional space required for arranging them separately, improve the space utilization of the housing 10, and facilitate the miniaturization of the product.

[0081] In the embodiment of the present application, optionally, the sweeper further comprises a locking shaft 44, the locking member 43 and the second gear 62 are spaced apart and connected to the locking shaft 44, the second transmission member 42 is sleeved on the locking member 43, and the locking member 43, the second transmission member 42 and the second gear 62 are coaxially arranged. Figure 1 As shown, the locking shaft 44 can extend in the vertical direction, so that the locking member 43 and the second gear 62 can be stacked in the vertical direction, reducing the horizontal size of the housing 10, and the second transmission member 42 is sleeved on the locking member 43, further improving space utilization. In addition, the locking shaft 44 passes through the locking member 43 and the second gear 62 at the same time, and also has good structural stability.

[0082] Optionally, in the embodiment of the present application, the side brush structure 30 further includes a side brush shaft 34, one end of which is located in the side brush housing 32, and the other end of which extends upward from the side brush housing 32; the side brush body 33 is connected to one end of the side brush shaft 34, and the first transmission member 41 is connected to the other end of the side brush shaft 34. In this way, the transmission connection between the side brush body 33 of the side brush structure 30 and the first transmission member 41 is realized through the side brush shaft 34, and the other end of the side brush shaft 34 extends upward from the side brush housing 32, so as to avoid the first transmission member 41 from affecting the movement of the housing 10. In addition, the first transmission member 41 can be sleeved on the outer periphery of the side brush shaft 34 and fixedly connected, which also has good force transmission stability.

[0083] In the embodiment of the present application, optionally, the side brush shaft 34 is arranged on the central axis of the side brush housing 32, and the third gear 63 of the second transmission assembly is arranged coaxially with the first transmission member 41. Figure 1 As shown, the side brush shaft 34 can extend in the vertical direction, so that the third gear 63 can be stacked with the first transmission member 41 in the vertical direction, reducing the horizontal size of the housing 10 and improving space utilization.

[0084] Optionally, in the embodiment of the present application, the side brush structure 30 can be connected to the housing 10 in a lifting manner. When the side brush structure 30 is lifted close to the housing 10, the locking structure locks the side brush structure 30 so that at least one brush strip 31 is located in the cleaning portion 20. In this way, when the sweeper returns to the base station for self-cleaning, when the side brush structure 30 is in a lifted state, it is far from the ground, so that the side brush structure 30 is prevented from contacting dirt and being contaminated again, so that the cleaning portion 20 can effectively clean the brush strip 31 of the side brush structure 30. In addition, when the sweeper is cleaning liquid dirt or performing a single-mopping mode, the side brush structure 30 is not used, and the side brush structure 30 can also be lifted to clean its brush strip 31 to improve cleaning efficiency.

[0085] In the embodiment of the present application, optionally, the side brush body 33 of the side brush structure 30 includes a side brush curved arm 35, and the brush strip 31 is connected to the side brush curved arm 35; the side brush structure 30 includes a side brush shell 32, and the side brush curved arm is bent and abuts against the upper surface inside the side brush shell 32, so that the side brush structure 30 is lifted close to the housing 10. In this way, the side brush curved arm 35 is bent and folded to abut against the upper surface inside the side brush shell 32, so that the side brush structure 30 is lifted.

[0086] For example, in an embodiment of the present application, when the side brush structure 30 performs floor cleaning operations, the side brush curved arm 35 can extend downward toward the ground. When the side brush structure 30 is switched to a raised state, the side brush curved arm 35 is bent and folded to extend toward an approximately horizontal direction, and is abutted against the upper surface of the inner side of the side brush shell 32 to remain in a raised state.

[0087] Optionally, in the embodiment of the present application, the side brush body 33 further includes a sleeve 36, the sleeve 36 is sleeved on the side brush shaft 34 of the side brush structure 30, the side brush curved arm 35 is connected to the outer periphery of the sleeve 36, and the side brush curved arm 35 is provided with a bending portion 37 at one end close to the sleeve 36; when the side brush housing 32 rotates along the second direction, the bending portion 37 bends so that the side brush curved arm 35 abuts against the upper surface inside the side brush housing 32. The bending portion 37 is provided at one end of the side brush curved arm 35 close to the sleeve 36, so that the side brush curved arm 35 is bent and turned at one end close to the sleeve 36, so that the side brush curved arm 35 has a higher lifting height.

[0088] For example, in an embodiment of the present application, the bending portion 37 can be a hollow structure, and the shape of the hollow structure can be semicircular, elliptical, rectangular, etc., which can be set according to the stress conditions. The embodiment of the present application may not limit the specific shape of the bending portion 37.

[0089] In the embodiment of the present application, optionally, a protruding abutment portion 38 is provided on the upper surface of the side brush housing 32, and the side brush curved arm 35 is bent and abutted against the abutment portion 38. In this way, the side brush curved arm 35 has a relatively stable and reliable abutment effect with the side brush housing 32 through the abutment portion 38, thereby improving the structural stability of the side brush structure 30 when it is in a raised state.

[0090] For example, when the sweeper of the embodiment of the present application is performing normal ground cleaning work, the incomplete gear of the first transmission member 41 and the transmission gear of the second transmission member 42 are normally meshed and transmitted, and the side brush performs normal ground cleaning work. When the sweeper returns to the base station for cleaning, the side brush structure 30 will be lifted to be in a lifted state, the drive motor will reverse, the first gear 61 and the second gear 62 and the third gear 63 will sequentially mesh and transmit to drive the side brush shell 32 to reverse, thereby driving the side brush body 33 to reverse, the side brush body 33 and the side brush shaft 34 can be connected by snap connection, the side brush shaft 34 and the incomplete gear of the first transmission member 41 rotate synchronously, when the incomplete gear rotates to mesh with the transmission gear of the second transmission member 42, because the transmission gear of the second transmission member 42 rotates synchronously with the outer side of the one-way bearing, the one-way bearing will be locked during reversal, so that the transmission gear, the incomplete gear, the side brush shaft 34 and the side brush body 33 stop rotating. At this time, the side brush housing 32 will still be reversed by the drive of the third gear 63, and the side brush body 33 and the side brush housing 32 will achieve relative rotation. At the same time, the abutment portion 38 protruding from the inner upper surface of the side brush housing 32 will abut against the upper surface of the side brush curved arm 35, so that the side brush curved arm 35 can be folded downward along its foldable bending portion 37, and this action will change the end of the side brush curved arm 35 from bending toward the ground to bending toward a nearly horizontal direction, thereby lifting the side brush. Since the position of the gear teeth of the incomplete gear can be set according to actual conditions, when the incomplete gear is meshed and engaged with the transmission gear, the side brush curved arm 35 is within the cleaning range of the roller brush of the cleaning portion 20 after the side brush structure 30 is lifted.

[0091] In the embodiment of the present application, for example, the side brush curved arm 35 has a certain bending angle. When the side brush structure 30 is in a descending state, the bending direction of the side brush curved arm 35 is set to bend downward. When the sleeve 36 and the side brush shell 32 move relative to each other, the abutment portion 38 on the side brush shell 32 abuts and presses down the sleeve 36. For example, after the abutment portion 38 on the side brush shell 32 abuts downward against the side brush curved arm 35, thereby driving the side brush curved arm 35 to fold downward, the bending direction of the side brush curved arm 35 changes. For example, the bending direction of the side brush curved arm 35 changes from bending downward to bending horizontally, thereby raising the height of the side brush curved arm 35. When the side brush curved arm 35 is in a raised state, the side brush structure 30 can be kept away from the ground. Therefore, when the cleaning robot is cleaning liquid dirt or performing a single mopping mode, the side brush structure 30 can be folded to keep the side brush structure 30 away from the ground, thereby preventing the side brush structure 30 from contacting dirt, improving the cleanliness of the side brush structure 30, and avoiding secondary pollution during the floor cleaning process.

[0092] Optionally, in the embodiment of the present application, the abutting portion 38 may include a first abutting inclined surface and a second abutting surface connected to the first abutting inclined surface, wherein when the side brush housing 32 rotates, the first abutting inclined surface abuts against the bent portion 37 of the side brush curved arm 35, driving the side brush curved arm 35 to rotate, so that the side brush structure 30 cleans the floor. When the side brush housing 32 and the sleeve 36 move relative to each other, the first abutting inclined surface forms an abutting guide for the bent portion 37 of the side brush curved arm 35, so that the bent portion 37 of the side brush curved arm 35 is folded downward, raising the height of the side brush structure 30, wherein when the side brush structure 30 is raised to the highest point, the second abutting surface abuts against the bent portion 37 of the side brush curved arm 35.

[0093] In the embodiment of the present application, the second abutting surface is connected with the first abutting inclined surface, or the second abutting surface can also smoothly transition with the first abutting inclined surface. For example, when the side brush shell 32 rotates, the first abutting inclined surface of the abutting portion 38 abuts against the bent portion 37 of the side brush curved arm 35, so that the abutting force applied by the abutting portion 38 to the bent portion 37 of the side brush curved arm 35 drives the side brush structure 30 and the sleeve 36 to rotate synchronously, so that the side brush structure 30 keeps in contact with the ground and cleans the ground. During the cleaning process of the side brush structure 30, when encountering some garbage with large particles or a certain thickness, due to the existence of the above-mentioned abutting force, the side brush structure 30 is kept pressed down and will not flip up with the garbage, which can further improve the cleaning effect of the side brush structure 30.

[0094] For example, in the embodiment of the present application, when the side brush housing 32 and the sleeve 36 move relative to each other, the first abutting slope on the abutting portion 38 forms an abutting guide for the bent portion 37 of the side brush curved arm 35. The abutting guide can be understood as that while the abutting portion 38 and the bent portion 37 of the side brush curved arm 35 are in abutment, the bent portion 37 of the side brush curved arm 35 moves along the first abutting slope under the action of the abutting force. Thus, the abutting force on the bent portion 37 of the side brush curved arm 35 can be gradually increased by the abutting portion 38 during the relative movement, so that the bent portion 37 of the side brush curved arm 35 is pressed down and folded downward, thereby changing the bending direction of the side brush curved arm 35. The bending direction of the side brush curved arm 35 changes from bending downward to bending horizontally, thereby raising the height of the side brush curved arm 35 from the ground. Furthermore, when the side brush structure 30 is lifted to the highest position, the bent portion 37 of the side brush curved arm 35 abuts against the second abutting surface. The second abutting surface is further provided with a chamfer at a position away from the first abutting inclined surface, and the chamfer is used to avoid the side brush structure 30.

[0095] In some optional embodiments, the second abutment surface on the abutment portion 38 may be extended along the circumferential length of the sleeve 36, thereby further increasing the relative rotation range between the side brush shell 32 and the sleeve 36, thereby facilitating the lifting or lowering control of the side brush structure 30.

[0096] For example, in some embodiments, the thickness of the bent portion 37 of the side brush curved arm 35 away from the center of the sleeve 36 in the radial direction of the sleeve 36 is greater than the thickness close to the center of the sleeve 36. In the embodiment of the present application, the thickness of the bent portion 37 of the side brush curved arm 35 refers to the thickness of the bent portion 37 of the side brush curved arm 35 along the axial direction of the sleeve 36. The central thickness of the bent portion 37 of the side brush curved arm 35 along the radial direction of the sleeve 36 is set to be thinner. Therefore, it is convenient for the abutting portion 38 to apply an abutting force to the bent portion 37 of the side brush curved arm 35, so that the thinner area of ​​the bent portion 37 of the side brush curved arm 35 can be bent downward, forming a foldable feature on the side brush curved arm 35. And the side brush curved arm 35 can change the bending direction of the side brush curved arm 35 under the folding of the bent portion 37 of the side brush curved arm 35, so as to achieve the height lifting of the side brush curved arm 35.

[0097] In some embodiments, the thickness of the bent portion 37 of the side brush curved arm 35 near the center of the sleeve 36 along the radial direction of the sleeve 36 is smaller than the thickness away from the center of the sleeve 36, so that the bent portion 37 of the side brush curved arm 35 can form an arc groove or a V-shaped groove along the radial direction of the sleeve 36. The bent portion 37 of the side brush curved arm 35 abuts against the abutment portion 38. Therefore, the bent portion 37 of the side brush curved arm 35 can be more easily abutted and pressed down, and the thinner center of the bent portion 37 of the side brush curved arm 35 can be deformed, driving the bent portion 37 of the side brush curved arm 35 to bend downward, thereby changing the bending direction of the side brush curved arm 35.

[0098] In an optional application embodiment, the bent portion 37 of the side brush curved arm 35 can be made of a rubber material. In the embodiment of the present application, the side brush curved arm 35 can be made of a rubber material with good deformation performance, so that the bent portion 37 of the side brush curved arm 35 has good deformation performance, and the structural stability of the bent portion 37 of the side brush curved arm 35 can be maintained during repeated deformation, thereby increasing the service life of the bent portion 37 of the side brush curved arm 35.

[0099] The inner circumference of the side brush body 33 may be provided with a side brush limiting portion, and the sleeve 36 may be provided with a transmission limiting portion, wherein the side brush limiting portion cooperates with the transmission limiting portion to limit the side brush body 33 along the radial direction of the sleeve 36 .

[0100] In the embodiment of the present application, a side brush limiting portion is provided on the inner circumference of the side brush body 33, and a transmission limiting portion is correspondingly provided on the sleeve 36. In some embodiments, the side brush limiting portion may be a limiting groove, and the transmission limiting portion may be a limiting protrusion that matches the shape of the limiting groove. In other embodiments, the side brush limiting portion may be a limiting protrusion, and the transmission limiting portion may be a limiting groove that matches the shape of the limiting protrusion. Thus, when the side brush body 33 is sleeved on the sleeve 36, the side brush limiting portion cooperates with the transmission limiting portion to limit the side brush body 33 in the radial direction of the sleeve 36.

[0101] For example, in the embodiment of the present application, the sleeve 36 can be a plastic part. After the side brush body 33 is sleeved on the sleeve 36, the sleeve 36 is injection molded for the second time, so that the side brush body 33 can be limited along the axial direction of the sleeve 36.

[0102] In some optional embodiments, the number of the side brush curved arms 35 may be at least two, and the at least two side brush curved arms 35 are distributed at equal angles about the central axis of the side brush body 33 in the horizontal circumferential direction of the side brush body 33. Those skilled in the art may determine the number of the side brush curved arms 35 according to actual design requirements, and no further limitation is made here. As a preferred embodiment, the number of the side brush curved arms 35 may be three.

[0103] In some optional application embodiments, the side brush structure 30 further includes an elastic member sleeved on the sleeve 36, the first end of the elastic member is fixed to the side brush shell 32, and the second end of the elastic member is fixed to the sleeve 36, so as to drive the side brush curved arm 35 to fold and reset through the deformation recovery of the elastic member. When the side brush shell 32 drives the side brush structure 30 to rotate, the elastic member provides a torsional force to keep the abutment portion 38 in abutment with the side brush structure 30. When the side brush shell 32 and the side brush structure 30 move relative to each other, the torsional force of the elastic member increases, and the torsional recovery of the elastic member drives the side brush structure 30 to fold and reset.

[0104] In the embodiment of the present application, the elastic member is sleeved on the sleeve 36, and its two ends are respectively fixed to the sleeve 36 and the side brush housing 32. For example, the elastic member may include a torsion spring, the first end of the elastic member is fixed to the upper half of the side brush housing 32, and the second end of the elastic member is fixed to the sleeve 36. Thus, the elastic member can form an elastic connection between the sleeve 36 and the side brush housing 32 along the circumference of the sleeve 36.

[0105] In other embodiments, the first end of the elastic member can be fixed to the lower half of the side brush housing 32, and the second end of the elastic member can be fixed to the sleeve 36, so that the elastic member can form an elastic connection between the sleeve 36 and the lower half of the side brush housing 32 along the circumference of the side brush transmission member. When the abutment portion 38 abuts against the side brush curved arm 35 and drives the side brush curved arm 35 to rotate synchronously, when the side brush structure 30 is in a descending state, the deformation torsional force of the elastic member maintains the abutment between the abutment portion 38 and the side brush curved arm 35, thereby keeping the side brush structure 30 in contact with the ground, and cleaning the ground through the rotation of the side brush structure 30.

[0106] When the side brush shell 32 is subjected to external force and rotates relative to the sleeve 36, the elastic potential energy (also called deformation torsional force) of the elastic member increases, thereby increasing the abutment force of the abutment portion 38 on the side brush curved arm 35. The abutment portion 38 presses down on the side brush curved arm 35, causing the side brush curved arm 35 to fold downward.

[0107] When the side brush housing 32 drives the sleeve 36 to rotate synchronously again, under the torsional recovery action of the elastic member, the bent portion 37 of the side brush curved arm 35 moves along the abutting portion 38, and the abutting force of the abutting portion 38 on the bent portion 37 of the side brush curved arm 35 gradually decreases, so that the bent portion 37 of the side brush curved arm 35 is deformed and restored. The bending direction of the side brush curved arm 35 is reset to a horizontal downward state. The abutting portion 38 and the side brush curved arm 35 are kept in contact by the deformation torsional force of the elastic member, so that the side brush structure 30 can keep in contact with the ground, and the ground can be cleaned by the rotation of the side brush structure 30.
