However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0056] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0057] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0060] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0061] A cleaning robot generally includes a body and a side brush. The side brush is detachably mounted on the bottom of the body. The side brush rotates when the cleaning robot performs a cleaning task and is used to sweep dust and garbage on the surface to be cleaned toward the suction port of the body to improve cleaning efficiency. However, when the cleaning robot encounters a raised obstacle during floor cleaning, the force exerted by the obstacle on the side brush when the side brush is cleaning the obstacle or passing over the obstacle can easily cause the side brush to fall off relative to the body. To solve this problem, the present application provides a side brush 10( Figure 2 As shown), cleaning robot 100 ( Figure 1 As shown), base station 300 ( Figure 10 As shown), and cleaning system 1000 ( Figure 10 shown).

[0062] See also Figures 1 to 4 313, and a second connection portion 313 is provided between the first connection portion 311 and the second connection portion 313; the side brush 10 includes a mounting base 11, and the mounting base 11 is provided with a mounting groove 111, and the mounting groove 111 is used for the connection portion 31 to be installed therein, and an anti-slip portion 113 is provided in the mounting groove 111, and the anti-slip portion 113 is connected to the inner wall of the mounting groove 111 and divides the mounting groove 111 into a first groove 1111 and a second groove 1113, the first groove 1111 is used to accommodate the first connection portion 311, and the second groove 1113 is used to accommodate the second connection portion 313; when the connection portion 31 is installed in the mounting groove 111, the anti-slip portion 113 is located in the gap 315 between the first connection portion 311 and the second connection portion 313.

[0063] Specifically, see Figure 1The cleaning robot 100 of the embodiment of the present application includes a side brush 10 and a body 30. The cleaning robot 100 is a device for cleaning the surface to be cleaned. The surface to be cleaned can be, but is not limited to, the floor, carpet, marble surface, or glass surface. The cleaning robot 100 can be a sweeping robot, a mopping robot, or a sweeping and mopping robot. The sweeping robot can be used to clean the surface to be cleaned, the mopping robot can be used to wipe the surface to be cleaned, and the sweeping and mopping robot can integrate the functions of the above two robots, that is, the sweeping and mopping robot can be used to sweep the surface to be cleaned, and can also be used to wipe and clean the surface to be cleaned. The cleaning robot 100 of the present application is explained by taking a sweeping robot as an example.

[0064] The body 30 is used to mount the side brush 10 and the cleaning components of the cleaning robot 100. The body 30 may be provided with a suction port, a blower, and a dust box. When the cleaning robot 100 is operating, the side brush 10 and the cleaning components may be used to sweep dirt (dust, debris, hair, etc.) on the surface to be cleaned to the vicinity of the suction port, and the blower may suck the dirt near the suction port into the dust box, thereby completing the cleaning of the surface to be cleaned.

[0065] See also Figure 1 and Figure 2 When the cleaning robot 100 is working, the side brush 10 can assist the cleaning part in cleaning. The side brush 10 can rotate relative to the main body 30 to gather the dirt on the surface to be cleaned toward the suction port, and then the dirt can be sucked into the dust box by the fan. In the case that the cleaning robot 100 includes a cleaning part and a side brush 10, the cleaning robot 100 has a better cleaning effect on the surface to be cleaned. Preferably, at least a portion of the side brush 10 can extend from the periphery of the main body 30, so that the side brush 10 can extend into locations that are difficult for the cleaning part to reach, such as walls, corners, or gaps, for cleaning. The side brush 10 can expand the cleaning range of the cleaning robot 100, and the cleaning robot 100 cleans the surface to be cleaned more comprehensively, and the cleaning effect of the cleaning robot 100 is better.

[0066] See also Figure 2 and Figure 3The connecting portion 31 is used to connect the body 30 to the side brush 10. The connecting portion 31 can rotate relative to the main body of the body 30, thereby driving the side brush 10 to rotate. The rotation of the side brush 10 can clean the surface to be cleaned. The mounting base 11 is used to mount the brush bar assembly 13 of the side brush 10. The mounting base 11 is also connected to the connecting portion 31 to ensure that the side brush 10 is firmly attached to the body 30 and prevent the side brush 10 from falling off the body 30. Preferably, the mounting base 11 and the connecting portion 31 are detachably connected, thereby facilitating removal of the side brush 10 from the body 30 for maintenance or replacement. Examples of detachable mounting methods include, but are not limited to, threaded connections, screw connections, and snap-fit ​​connections. The snap-fit ​​connection between the mounting base 11 and the connecting portion 31 of the present application makes installation and removal of the side brush 10 from the body 30 simple and quick, providing a good user experience.

[0067] When the side brush 10 is engaged with the body 30, the first connecting portion 311 extends into the first groove 1111, the second connecting portion 313 extends into the second groove 1113, and the anti-detachment portion 113 is located in the gap 315 between the first groove 1111 and the second groove 1113. When the cleaning robot 100 moves over the surface to be cleaned and the side brush 10 encounters an obstacle, causing the side brush 10 to scrape against the obstacle (for example, when the cleaning robot 100 climbs a step and the side brush 10 scrapes against the edge of the step), in most cleaning scenarios, the force exerted by the obstacle on the mounting base 11 is applied to one side of the mounting base 11. This force causes the mounting base 11 to be unbalanced, causing the mounting base 11 to tilt relative to the surface being cleaned. This makes it easy for the connecting portion 31 to disengage from the other side of the mounting base 11. Specifically, when the force of the obstacle acts on one side of the mounting base 11, the obstacle contacts the side of the mounting base 11 and causes it to move upward. Because the mounting groove 111 of the mounting base 11 is connected to the connecting portion 31, the point where the mounting groove 111 and the connecting portion 31 meet acts as a fulcrum. When one side of the mounting base 11 moves upward under the action of an obstacle, the other side of the mounting base 11 moves downward. The torque generated by the force exerted by the obstacle on the mounting base 11 causes the other side of the mounting base 11 to move downward, and the deformation of the connecting portion 31 is greater. The mounting groove 111 on this side first disengages from the connecting portion 31, and then the entire connecting portion 31 separates from the mounting groove 111. In other words, when the side brush 10 rubs against the obstacle, the mounting base 11 is likely to fall away from the connecting portion 31. During the process of the mounting base 11 falling away from the connecting portion 31, the connecting portion 31 is subjected to a certain amount of deformation, which causes the mounting base 11 and the connecting portion 31 to be released, and the mounting base 11 is completely separated from the connecting portion 31, thereby causing the side brush 10 to fall off and separate from the body 30.

[0068] See also Figures 2 to 4When the anti-detachment portion 113 is provided in the mounting groove 111, the anti-detachment portion 113 is located in the gap between the first connecting portion 311 and the second connecting portion 313. When the side brush 10 rubs against an obstacle and is subjected to a downward force, the mounting base 11 tends to fall off relative to the connecting portion 31. When an obstacle contacts one side of the mounting seat 11, the torque formed by the force of the obstacle on the mounting seat 11 causes the other side of the mounting seat 11 to move downward. Since the anti-slip portion 113 is located between the first connecting portion 311 and the second connecting portion 313, the anti-slip portion 113 can effectively prevent the first connecting portion 311 and the second connecting portion 313 from undergoing a large deformation toward the direction of the gap 315. The gap direction is perpendicular to the height direction, that is, the anti-slip portion 113 can effectively reduce the deformation of the connecting portion 31, so that the connecting portion 31 and the mounting seat 11 can remain engaged, and the mounting seat 11 is not easy to fall off relative to the connecting portion 31. When the side brush 10 rubs against an obstacle, the connection between the side brush 10 and the fuselage 30 is relatively stable, and the side brush 10 is not easy to fall off relative to the fuselage 30.

[0069] Furthermore, when an anti-slip portion 113 is provided within the mounting groove 111 and the width of the anti-slip portion 113 is substantially the same as the width of the gap 315, the contact between the first connecting portion 311 and the anti-slip portion 113 can generate a first frictional force, and the contact between the second connecting portion 313 and the anti-slip portion 113 can generate a second frictional force. That is, after the connecting portion 31 is connected to the mounting seat 11, the anti-slip portion 113 can increase the frictional force between the connecting portion 31 and the mounting seat 11, thereby providing a more stable connection between the connecting portion 31 and the mounting seat 11. If the side brush 10 rubs against an obstacle and is subjected to the force of the obstacle, the frictional force between the connecting portion 31 and the mounting seat 11 can further prevent the mounting seat 11 from falling away from the connecting portion 31, thereby preventing the side brush 10 from falling relative to the body 30.

[0070] Furthermore, the mounting base 11 is fixedly connected to the connecting portion 31, so that when the connecting portion 31 rotates relative to the body 30, it can drive the side brush 10 to rotate. When the anti-slip portion 113 is located within the gap 315, the anti-slip portion 113 can also prevent the mounting base 11 from rotating in the circumferential direction relative to the connecting portion 31, thereby making the connection between the side brush 10 and the connecting portion 31 more stable.

[0071] In the side brush 10 of the embodiment of the present application, the mounting base 11 and the connecting portion 31 can be connected by a snap fit. When the mounting base 11 and the connecting portion 31 are connected, the first connecting portion 311 is located within the first groove 1111, the second connecting portion 313 is located within the second groove 1113, and the anti-slip portion 113 is located between the first connecting portion 311 and the second connecting portion 313. If the side brush 10 is subjected to forces caused by rubbing against an obstacle and the mounting base 11 tends to separate from the connecting portion 31, the anti-slip portion 113 can prevent the first connecting portion 311 and the second connecting portion 313 from significantly deforming toward the gap 315, thereby preventing the connecting portion 31 and the mounting base 11 from being disengaged. This provides a more stable connection between the connecting portion 31 and the mounting base 11, making it less likely that the mounting base 11 will fall off the connecting portion 31, and thus the side brush 10 will be less likely to fall off the body 30.

[0072] The side brush 10 will be further described below with reference to the accompanying drawings.

[0073] See also Figure 4 、 Figure 5 、 Figure 6 and Figure 9In some embodiments, the width w1 of the anti-slip portion 113 is smaller than the width w2 of the gap 315. In this case, during the insertion of the connecting portion 31 into the mounting slot 111, a gap can be formed between the first connecting portion 311 and the anti-slip portion 113, and a gap can also be formed between the second connecting portion 313 and the anti-slip portion 113. This eliminates friction between the first connecting portion 311 and the anti-slip portion 113, and also eliminates friction between the second connecting portion 313 and the anti-slip portion 113, facilitating insertion of the connecting portion 31 into the mounting slot 111. The user only needs to apply a small amount of force to insert the connecting portion 31 into the anti-slip portion 113, providing a better user experience. Furthermore, when the width w1 of the anti-slip portion 113 is smaller than the width w2 of the gap 315, strict alignment between the connecting portion 31 and the mounting base 11 is not required when the connecting portion 31 is inserted into the mounting slot 111, making the connection between the mounting base 11 and the connecting portion 31 relatively simple and quick. In addition, the first connecting portion 311 and / or the second connecting portion 313 can undergo minor deformation when being installed or removed from the mounting groove 111, facilitating installation and removal. It should be noted that this deformation is smaller than the deformation that would occur if the mounting groove 111 were not designed with the anti-detachment portion 113. This design facilitates installation and removal while preventing the side brush 10 from falling off when it rubs against an obstacle. It is understandable that when an obstacle acts on one side or side of the mounting base 11, it can easily cause the mounting base 11 to tilt, and the torque generated by the force of the obstacle acting on one side or side of the mounting base 11 can cause the connecting portion 31 to undergo significant deformation. This significant deformation can cause the other side of the mounting base 11 to disengage from the connecting portion 31, thereby causing the side brush 10 to detach from the body. When an obstacle acts on the middle position of the mounting seat 11, the mounting seat 11 will not tilt. The force exerted by the obstacle on the mounting seat 11 is upward, and the direction of this force is the same as the installation direction of the mounting groove 111 and the connecting portion 31. Therefore, when an obstacle acts on the middle position of the mounting seat 11, the connecting portion 31 will not be separated from the mounting groove 111. It should be noted that in most scenarios where the cleaning robot is sweeping the floor, the force exerted by the obstacle on the mounting seat 11 acts on the side of the mounting seat 11, not the middle position of the mounting seat 11. Therefore, the anti-detachment portion 113 designed in the mounting groove 111 can prevent the side brush 10 from falling off the body 30. When the side brush 10 needs to be separated from the body 30, the mounting seat 11 can be pulled away from the body 30 along the height direction H. At this time, the connecting portion 31 undergoes a slight deformation and can be separated from the mounting seat 11, thereby facilitating the installation and removal of the connecting portion 31 and the mounting groove 111.

[0074] See also Figure 4 、 Figure 5 、 Figure 6 and Figure 9In other embodiments, the direction in which the connecting portion 31 is inserted into the mounting groove 111 is the height direction H, and the length h1 of the anti-slip portion 113 along the height direction H is less than the depth L of the mounting groove 111 along the height direction H.

[0075] Since the connection portion 31 and the mounting seat 11 are snap-fitted, the connection portion 31 may be squeezed by the sidewalls of the mounting groove 111 during the process of the connection portion 31 extending into the mounting groove 111, thereby causing a certain amount of deformation. When the connection portion 31 and the mounting seat 11 are installed in place, the connection portion 31 can restore its original shape. When the length h1 of the anti-slip portion 113 along the height direction H is less than the depth L of the mounting groove 111 along the height direction H, in the width direction W from the first connection portion 311 to the second connection portion 313, when the connection portion 31 does not correspond to the anti-slip portion 113, it is convenient for the first connection portion 311 and the second connection portion 313 to deform in the direction of the gap 315, so that the connection portion 31 can smoothly extend into the mounting groove 111 to be firmly connected to the mounting groove 111. Furthermore, when the length h1 of the anti-slip portion 113 along the height direction H is smaller than the depth L of the mounting groove 111 along the height direction H, the anti-slip portion 113 is smaller in size, which can save certain material costs and the overall weight of the mounting seat 11 is also lighter.

[0076] See also Figure 4 、 Figure 5 、 Figure 6 and Figure 9 In some other embodiments, the width w1 of the anti-slip portion 113 is smaller than the width w2 of the gap 315, and the direction in which the connecting portion 31 is inserted into the mounting groove 111 is the height direction H. The length h1 of the anti-slip portion 113 along the height direction H is smaller than the depth L of the mounting groove 111 along the height direction H. In this case, when the mounting seat 11 and the connecting portion 31 are connected, no large external force is required to secure the mounting seat 11 and the connecting portion 31 in place, making the connection between the mounting seat 11 and the connecting portion 31 relatively simple.

[0077] See also Figures 4 to 6 In some embodiments, the anti-slip portion 113 extends from the slot opening of the mounting slot 111 into the mounting slot 111 , that is, the anti-slip portion 113 is disposed at a position close to the slot opening of the mounting slot 111 .

[0078] At this time, after the connecting part 31 is installed with the mounting groove 111, the anti-slip portion 113 is located at a position in the gap 315 that is closer to the fuselage 30. When an obstacle acts on the side of the mounting seat 11, the position where the connecting part 31 is subjected to greater force is the position close to the fuselage 30. Then, the deformation amount at this position is relatively large, and the anti-slip portion 113 is set at a position close to the fuselage 30, which can better prevent the connecting part 31 from undergoing large deformation.

[0079] As the connecting portion 31 extends into the mounting groove 111, it initially aligns with the anti-slip portion 113, causing minimal deformation of the connecting portion 31. As the connecting portion 31 continues to extend downward toward the bottom of the mounting groove 111, it may be squeezed by the sidewalls of the mounting groove 111, causing significant deformation. Once the connecting portion 31 is properly seated in the mounting groove 111, it returns to its original shape.

[0080] When the side brush 10 encounters an obstacle and tends to separate from the connecting portion 31 (at this time, the force exerted by the obstacle on the side brush 10 is relatively small), the anti-detachment portion 113 located near the notch of the mounting groove 111 can effectively prevent the first connecting portion 311 and the second connecting portion 313 from significantly deforming toward the gap 315. As a result, the connecting portion 31 is not easily disengaged from the mounting seat 11, and the mounting seat 11 is not easily separated from the connecting portion 31, resulting in a more stable connection between the side brush 10 and the body 30. If the anti-detachment portion 113 is located near the engagement point between the connecting portion 31 and the mounting seat 11, the anti-detachment portion 113 will prevent the deformation of the connecting portion 31, making it difficult to remove the side brush 10 from the body 30, and the user experience will be poor.

[0081] See also Figures 6 to 9 In some embodiments, the length h3 of the gap 315 along the height direction H is greater than the length h1 of the anti-slip portion 113 along the height direction H. In this case, the connecting portion 31 can easily pass through the anti-slip portion 113 and continue to extend toward the bottom of the mounting groove 111. After the connecting portion 31 is engaged with the mounting seat 11, the connection between the connecting portion 31 and the mounting seat 11 is relatively stable. If the length h3 of the gap 315 along the height direction H is less than or equal to the length h1 of the anti-slip portion 113 along the height direction H, during the process of inserting the connecting portion 31 into the mounting groove 111, after the gap 315 cooperates with the anti-slip portion 113, the connecting portion 31 cannot continue to extend toward the bottom of the mounting groove 111, and it is difficult for the connecting portion 31 to form an engaging connection with the mounting seat 11.

[0082] See also Figures 5 to 8 In some embodiments, the first connecting portion 311 is provided with a first latching protrusion 3111 at the end away from the fuselage 30, and a first locking portion 11111 is provided in the first groove 1111. When the connecting portion 31 is installed in the mounting groove 111, the first locking portion 11111 is used to prevent the first latching protrusion 3111 from moving in a direction away from the mounting groove 111.

[0083] The first locking protrusion 3111 protrudes from the main body of the first connecting portion 311 in a direction away from the gap 315. The first engaging portion 11111 protrudes from the inner wall of the first groove 1111 in a direction close to the center line of the mounting groove 111. The center line of the mounting groove 111 is the central axis of the mounting groove 111 in the height direction H. When the connecting portion 31 extends into the mounting groove 111, the first locking protrusion 3111 contacts the first engaging portion 11111, and the first engaging portion 11111 squeezes the first locking protrusion 3111 ( Figure 7 As shown in FIG, the first connecting portion 311 is deformed toward the gap 315, so that the connecting portion 311 can continue to extend downward toward the bottom of the mounting groove 111. In the height direction H, when the first locking protrusion 3111 is located below the first engaging portion 11111, the first connecting portion 311 can restore its original shape (away from the gap 315). Figure 8 As shown), at this time, the first locking protrusion 3111 cooperates with the first locking portion 11111, and the first locking portion 11111 can prevent the first connecting portion 311 from moving toward the notch of the installation groove 111.

[0084] When the first connecting portion 311 includes a first latching protrusion 3111 and a first engaging portion 11111 is disposed within the first groove 1111, the engagement between the first latching protrusion 3111 and the first engaging portion 11111 securely connects the connecting portion 31 to the mounting base 11, preventing the mounting base 11 from detaching from the connecting portion 31. If the side brush 10 encounters an obstacle and tends to detach from the connecting portion 31, the first engaging force between the first latching protrusion 3111 and the first engaging portion 11111 prevents the mounting base 11 from detaching from the connecting portion 31. Furthermore, the anti-detachment portion 113 effectively prevents the first connecting portion 311 from significantly deforming toward the gap 315, thereby further preventing the first latching protrusion 3111 and the first engaging portion 11111 from disengaging. This provides a more secure connection between the connecting portion 31 and the mounting base 11, preventing the side brush 10 from detaching from the body 30.

[0085] See also Figures 5 to 8 In some embodiments, along the height direction H, the anti-slip portion 113 and the first engaging portion 11111 are arranged in sequence, and the distance between the anti-slip portion 113 and the first engaging portion 11111 is greater than or equal to the length of the first engaging protrusion 3111 in the height direction H.

[0086] In the height direction H, the position of the anti-slip portion 113 is higher than that of the first engaging portion 11111. When the distance between the anti-slip portion 113 and the first engaging portion 11111 is greater than or equal to the length of the first latching protrusion 3111 in the height direction H, when the first latching protrusion 3111 contacts the first engaging portion 11111 and is squeezed by the first engaging portion 11111, the first latching protrusion 3111 does not correspond to the anti-slip portion 113 in the width direction W from the first connecting portion 311 to the second connecting portion 313. As a result, the first latching protrusion 3111 can be deformed toward the gap 315 under the action of the squeezing force, so that the connecting portion 31 can continue to extend downward toward the bottom of the mounting groove 111.

[0087] If the distance between the anti-slip portion 113 and the first engaging portion 11111 is less than the length of the first engaging protrusion 3111 in the height direction H, when the first engaging protrusion 3111 contacts and is squeezed by the first engaging portion 11111, at least a portion of the first engaging protrusion 3111 will still correspond to the anti-slip portion 113 in the width direction W. At this time, the first engaging protrusion 3111 tends to deform toward the gap 315 under the action of the squeezing force, but the anti-slip portion 113 prevents the first connecting portion 311 from deforming toward the gap 315, preventing the first engaging protrusion 3111 from deforming sufficiently toward the gap 315. The first engaging protrusion 3111 will become stuck between the first engaging portion 11111 and the anti-slip portion 113, making it difficult for the connecting portion 31 to continue extending downward toward the bottom of the mounting groove 111, and thus making it difficult for the connecting portion 31 to engage with the mounting base 11.

[0088] See also Figures 5 to 8 In other embodiments, the second connecting portion 313 is provided with a second latching protrusion 3131 at the end away from the fuselage 30, and a second locking portion 11131 is provided in the second groove 1113. When the connecting portion 31 is installed in the mounting slot 111, the second locking portion 11131 is used to prevent the second latching protrusion 3131 from moving in a direction away from the mounting slot 111.

[0089] The second locking protrusion 3131 protrudes from the body of the second connecting portion 313 in a direction away from the gap 315. The second engaging portion 11131 protrudes from the inner wall of the second groove 1113 in a direction close to the center of the mounting groove 111. When the connecting portion 31 is inserted into the mounting groove 111, the second locking protrusion 3131 contacts the second engaging portion 11131, and the second engaging portion 11131 squeezes the second locking protrusion 3131, so that the second connecting portion 313 is deformed in the direction of the gap 315 ( Figure 7 As shown), the connecting portion 31 can continue to extend downward toward the bottom of the installation groove 111. In the height direction H, when the second locking protrusion 3131 is located below the second engaging portion 11131, the second connecting portion 313 can restore its initial shape (away from the gap 315) Figure 8As shown), at this time, the second locking protrusion 3131 cooperates with the second locking portion 11131, and the second locking portion 11131 can prevent the second connecting portion 313 from moving toward the direction of the notch of the installation groove 111.

[0090] When the second connecting portion 313 includes a second latching protrusion 3131 and a second engaging portion 11131 is disposed within the second groove 1113, the engagement between the second latching protrusion 3131 and the second engaging portion 11131 secures the connection between the connecting portion 31 and the mounting base 11, preventing the mounting base 11 from detaching from the connecting portion 31. If the side brush 10 encounters an obstacle and tends to detach from the connecting portion 31, the second engaging force between the second latching protrusion 3131 and the second engaging portion 11131 prevents the mounting base 11 from detaching from the connecting portion 31. Furthermore, the anti-detachment portion 113 effectively prevents the second connecting portion 313 from significantly deforming toward the gap 315, thereby further preventing the second latching protrusion 3131 and the second engaging portion 11131 from disengaging. This provides a more secure connection between the connecting portion 31 and the mounting base 11, preventing the side brush 10 from detaching from the body 30.

[0091] See also Figures 5 to 8 In some embodiments, the anti-slip portion 113 and the second engaging portion 11131 are arranged in sequence along the height direction H, and the distance between the anti-slip portion 113 and the second engaging portion 11131 is greater than or equal to the length of the second engaging protrusion 3131 in the height direction H.

[0092] In the height direction H, the position of the anti-slip portion 113 is higher than the position of the second engaging portion 11131. When the distance between the anti-slip portion 113 and the second engaging portion 11131 is greater than or equal to the length of the second engaging protrusion 3131 in the height direction H, when the second engaging protrusion 3131 contacts and is squeezed by the second engaging portion 11131, the second engaging protrusion 3131 does not correspond to the anti-slip portion 113 in the width direction W. As a result, the second engaging protrusion 3131 can be deformed toward the gap 315 under the action of the squeezing force, so that the connecting portion 31 can continue to extend downward into the mounting groove 111.

[0093] If the distance between the anti-slip portion 113 and the second engaging portion 11131 is less than the length of the second engaging protrusion 3131 in the height direction H, when the second engaging protrusion 3131 contacts and is squeezed by the second engaging portion 11131, at least a portion of the second engaging protrusion 3131 will still correspond to the anti-slip portion 113 in the width direction W. At this point, the second engaging protrusion 3131 tends to deform toward the gap 315 under the action of the squeezing force, but the anti-slip portion 113 prevents the second connecting portion 313 from deforming toward the gap 315, preventing the second engaging protrusion 3131 from sufficiently deforming toward the gap 315. The second engaging protrusion 3131 will become stuck between the second engaging portion 11131 and the anti-slip portion 113, making it difficult for the connecting portion 31 to continue extending downward into the mounting groove 111, thereby preventing the connecting portion 31 from engaging with the mounting base 11.

[0094] See also Figures 5 to 8 In some other embodiments, the first connecting portion 311 is provided with a first latching protrusion 3111 at the end away from the fuselage 30, and a first latching portion 11111 is provided in the first groove 1111. When the connecting portion 31 is installed in the mounting slot 111, the first latching portion 11111 is used to prevent the first latching protrusion 3111 from moving in a direction away from the mounting slot 111; and the second connecting portion 313 is provided with a second latching protrusion 3131 at the end away from the fuselage 30, and a second latching portion 11131 is provided in the second groove 1113. When the connecting portion 31 is installed in the mounting slot 111, the second latching portion 11131 is used to prevent the second latching protrusion 3131 from moving in a direction away from the mounting slot 111.

[0095] At this time, the cooperation between the first latching protrusion 3111 and the first engaging portion 11111 generates a first engaging force, while the cooperation between the second latching protrusion 3131 and the second engaging portion 11131 generates a second engaging force. The first and second engaging forces securely connect the connecting portion 31 to the mounting base 11, preventing the mounting base 11 from detaching from the connecting portion 31. If the side brush 10 encounters an obstacle and tends to detach from the connecting portion 31, the first and second engaging forces effectively prevent the mounting base 11 from detaching from the connecting portion 31. Furthermore, the anti-detachment portion 113 effectively prevents the first and second connecting portions 311, 313 from significantly deforming toward the gap 315, thereby effectively preventing the first latching protrusion 3111 from disengaging from the first engaging portion 11111 and the second latching protrusion 3131 from disengaging from the second engaging portion 11131. This further strengthens the connection between the connecting portion 31 and the mounting base 11, preventing the side brush 10 from detaching from the body 30.

[0096] See also Figures 5 to 8Furthermore, in some embodiments, the first locking portion 11111 includes a first locking surface 11112, and in the direction in which the connecting portion 31 is inserted into the mounting groove 111, the distance between the first locking surface 11112 and the center line of the mounting groove 111 gradually increases.

[0097] The center line of the mounting groove 111 is the center axis of the mounting groove 111 in the height direction H. The first engaging surface 11112 is located at the bottom of the first engaging portion 11111, and the first engaging surface 11112 is an inclined surface or an arc surface. The bottom of the first latching protrusion 3111 includes a first mating surface 3113. In the direction in which the connecting portion 31 is inserted into the mounting groove 111, the distance between the first mating surface 3113 and the center line of the mounting groove 111 gradually increases, and the first mating surface 3113 is also an inclined surface or an arc surface. When the connecting portion 31 is engaged with the mounting seat 11, the first latching protrusion 3111 is located below the first engaging portion 11111. At this time, the first engaging surface 11112 is engaged with the first mating surface 3113 ( Figure 8 When the side brush 10 encounters an obstacle and tends to separate from the connecting portion 31, the first engaging surface 11112 is used to prevent the first engaging protrusion 3111 from moving toward the notch of the mounting groove 111, thereby ensuring a more stable connection between the connecting portion 31 and the mounting base 11.

[0098] The first engaging surface 11112 and the first mating surface 3113 are substantially parallel. When a user applies a large force to the mounting base 11 to remove the side brush 10 from the body 30, the cooperation between the first engaging surface 11112 and the first mating surface 3113 can guide the first engaging protrusion 3111. When the mounting base 11 moves away from the connecting portion 31 under the action of an external force, the first engaging protrusion 3111 can move along the first engaging surface 11112 to disengage from the first engaging portion 11111, thereby disconnecting the mounting base 11 from the connecting portion 31.

[0099] See also Figures 5 to 8 In other embodiments, the second engaging portion 11131 includes a second engaging surface 11132 , and in the direction in which the connector is inserted into the mounting slot 111 , the distance between the second engaging surface 11132 and the center line of the mounting slot 111 gradually increases.

[0100] The second engaging surface 11132 is located at the bottom of the second engaging portion 11131. The second engaging surface 11132 is an inclined surface or an arc surface. The bottom of the second engaging protrusion 3131 includes a second mating surface 3133. In the direction in which the connecting portion 31 is inserted into the mounting groove 111, the distance between the second mating surface 3133 and the center line of the mounting groove 111 gradually increases. The second mating surface 3133 is also an inclined surface or an arc surface. When the connecting portion 31 is engaged with the mounting seat 11, the second engaging protrusion 3131 is located below the second engaging portion 11131. At this time, the second engaging surface 11132 is engaged with the second mating surface 3133 ( Figure 8 When the side brush 10 encounters an obstacle and tends to separate from the connecting portion 31, the second engaging surface 11132 is used to prevent the second engaging protrusion 3131 from moving toward the notch of the mounting groove 111, thereby ensuring a more stable connection between the connecting portion 31 and the mounting base 11.

[0101] The second engaging surface 11132 and the second mating surface 3133 are substantially parallel. When a user applies a large force to the mounting base 11 to remove the side brush 10 from the body 30, the engagement between the second engaging surface 11132 and the second mating surface 3133 can guide the second latching protrusion 3131. When the mounting base 11 is moved away from the connecting portion 31 under the action of an external force, the second latching protrusion 3131 can move along the second engaging surface 11132 to disengage from the second engaging portion 11131, thereby disconnecting the mounting base 11 from the connecting portion 31.

[0102] See also Figures 5 to 8 In some other embodiments, the first locking portion 11111 includes a first locking surface 11112, and the distance between the first locking surface 11112 and the center line of the mounting groove 111 gradually increases in the direction in which the connecting portion 31 is inserted into the mounting groove 111; the second locking portion 11131 includes a second locking surface 11132, and the distance between the second locking surface 11132 and the center line of the mounting groove 111 gradually increases in the direction in which the connecting member is inserted into the mounting groove 111.

[0103] When the side brush 10 encounters an obstacle and tends to separate from the connecting portion 31, the first engaging surface 11112 is used to prevent the first engaging protrusion 3111 from moving toward the notch of the mounting groove 111, and the second engaging surface 11132 is used to prevent the second engaging protrusion 3131 from moving toward the notch of the mounting groove 111, thereby making the connection between the connecting portion 31 and the mounting seat 11 more stable, and the side brush 10 is not easy to fall off relative to the body 30.

[0104] When the user needs to remove the side brush 10 from the body 30, the user can apply a large force to the mounting base 11. At this time, the cooperation between the first engaging surface 11112 and the first mating surface 3113 can guide the first latching protrusion 3111, and the cooperation between the second engaging surface 11132 and the second mating surface 3133 can guide the second latching protrusion 3131. When the mounting base 11 moves away from the connecting portion 31 under the action of an external force, the first latching protrusion 3111 can move along the first engaging surface 11112 to release the engagement with the second engaging portion 11131, and the second latching protrusion 3131 can move along the second engaging surface 11132 to release the engagement with the second engaging portion 11131, thereby releasing the mounting base 11 from the connecting portion 31.

[0105] See also Figures 5 to 8 Furthermore, in some embodiments, a first card slot 11113 is provided in the first slot 1111. The first card slot 11113 is closer to the bottom of the installation slot 111 than the first engaging portion 11111. The first card slot 11113 is connected to the first card protrusion 3111.

[0106] The first engaging groove 11113 is formed by being recessed from the inner wall of the first groove 1111 in a direction away from the centerline of the mounting groove 111. In the height direction H, the anti-slip portion 113, the first engaging portion 11111, and the first engaging groove 11113 are arranged in sequence, and the first engaging groove 11113 is used to accommodate the first engaging protrusion 3111. When the connecting portion 31 extends into the mounting groove 111, when the first engaging protrusion 3111 is located below the first engaging portion 11111 to cooperate with the first engaging surface 11112, the first engaging protrusion 3111 can be located in the first engaging groove 11113. At this time, the first engaging protrusion 3111 is no longer squeezed by the first engaging portion 11111 and the inner wall of the mounting groove 111, and the first connecting portion 311 can return to its original shape. In the width direction W, the surface (vertical surface) of the first engaging protrusion 3111 away from the gap 315 is spaced far apart from the surface (vertical surface) of the main body of the first engaging portion 11111. When the side brush 10 encounters an obstacle and tends to separate from the connecting portion 31, the first latching protrusion 3111 is difficult to leave the first latching groove 11113 to disengage from the first engaging portion 11111, thereby making the connection between the connecting portion 31 and the mounting seat 11 more stable and the mounting seat 11 less likely to fall off relative to the connecting portion 31.

[0107] When the first engaging portion 11111 and the first engaging slot 11113 are provided in the first groove 1111, the first engaging protrusion 3111 passes through the first engaging portion 11111 and enters the first engaging slot 11113. The first engaging slot 11113 and the first engaging portion 11111 are jointly used to limit the first engaging protrusion 3111 to be located in the first engaging slot 11113. The first connecting portion 311 is not easily disengaged from the mounting seat 11, so that the connection between the connecting portion 31 and the mounting seat 11 is relatively stable, and the side brush 10 is not easily detached from the body 30.

[0108] See also Figures 5 to 8 In other embodiments, a second card slot 11133 is provided in the second slot 1113 . The second card slot 11133 is closer to the bottom of the installation slot 111 than the second engaging portion 11131 . The second card slot 11133 is connected to the second engaging protrusion 3131 .

[0109] The second engaging groove 11133 is formed by being recessed from the inner wall of the second groove 1113 in a direction away from the centerline of the mounting groove 111. In the height direction H, the anti-slip portion 113, the second engaging portion 11131, and the second engaging groove 11133 are arranged in sequence, and the second engaging groove 11133 is used to accommodate the second engaging protrusion 3131. When the connecting portion 31 extends into the mounting groove 111, the second engaging protrusion 3131 is located below the second engaging portion 11131 to cooperate with the second engaging surface 11132, and the second engaging protrusion 3131 can be located in the second engaging groove 11133. At this time, the second engaging protrusion 3131 is no longer squeezed by the second engaging portion 11131 or the inner wall of the mounting groove 111, and the second connecting portion 313 can return to its original shape. In the width direction W, the surface (vertical surface) of the second engaging protrusion 3131 away from the gap 315 is spaced far apart from the surface (vertical surface) of the main body of the second engaging portion 11131. When the side brush 10 encounters an obstacle and tends to separate from the connecting portion 31, the second latching protrusion 3131 is difficult to leave the second latching groove 11133 to release the engagement with the second engaging portion 11131, thereby making the connection between the connecting portion 31 and the mounting seat 11 more stable and preventing the mounting seat 11 from falling off relative to the connecting portion 31.

[0110] When the second engaging portion 11131 and the second engaging slot 11133 are provided in the second groove 1113, the second engaging protrusion 3131 passes through the second engaging portion 11131 and enters the second engaging slot 11133. The second engaging slot 11133 and the second engaging portion 11131 are jointly used to limit the second engaging protrusion 3131 to be located in the second engaging slot 11133. The second connecting portion 313 is not easily disengaged from the mounting seat 11, so that the connection between the connecting portion 31 and the mounting seat 11 is relatively stable, and the side brush 10 is not easily detached from the body 30.

[0111] See also Figures 5 to 8In some other embodiments, a first card slot 11113 is provided in the first slot 1111, the first card slot 11113 is closer to the bottom of the installation slot 111 than the first engaging portion 11111, and the first card slot 11113 is connected to the first engaging protrusion 3111; a second card slot 11133 is provided in the second slot 1113, the second card slot 11133 is closer to the bottom of the installation slot 111 than the second engaging portion 11131, and the second card slot 11133 is connected to the second engaging protrusion 3131.

[0112] At this time, the first card slot 11113 and the first engaging portion 11111 are jointly used to limit the first engaging protrusion 3111 to be located in the first card slot 11113, and the first connecting portion 311 is not easily disengaged from the mounting seat 11. The second card slot 11133 and the second engaging portion 11131 are jointly used to limit the second engaging protrusion 3131 to be located in the second card slot 11133, and the second connecting portion 313 is not easily disengaged from the mounting seat 11, so that the connection between the connecting portion 31 and the mounting seat 11 is more stable, which can further avoid the problem of the side brush 10 falling off relative to the fuselage 30.

[0113] See also Figures 5 to 8 In some embodiments, the first connecting portion 311 is provided with a first latching protrusion 3111 at the end away from the fuselage 30, and a first latching groove 11113 is provided in the first groove 1111. When the connecting portion 31 is installed in the installation groove 111, the first latching groove 11113 is engaged with the first latching protrusion 3111.

[0114] In this case, the first engaging portion 11111 may not be provided in the first groove 1111; instead, only the first engaging groove 11113 may be provided in the first groove 1111. The first engaging groove 11113 may be located at the bottom of the first groove 1111, with the sidewalls of the first engaging groove 11113 further away from the centerline of the mounting groove 111 than the sidewalls of the first groove 1111. As the connecting portion 31 extends into the mounting groove 111, the first engaging protrusion 3111 may be squeezed by the sidewalls of the first groove 1111, causing the first connecting portion 311 to deform toward the gap 315. After the first engaging protrusion 3111 enters the first engaging groove 11113, the first connecting portion 311 may return to its original shape in a direction away from the gap, at which point the first engaging protrusion 3111 is located within the first groove 1111. The top wall of the first slot 11113 can cooperate with the first protrusion 3111. When the side brush 10 encounters an obstacle and tends to separate from the connecting part 31, the top wall of the first slot 11113 can be used to prevent the first protrusion 3111 from moving toward the notch of the mounting slot 111, so that the connection between the connecting part 31 and the mounting seat 11 is more stable.

[0115] In this embodiment, the first groove 1111 has a relatively simple structure and is easy to manufacture. Furthermore, the cooperation between the first engaging groove 11113 and the first engaging protrusion 3111 effectively prevents the first engaging protrusion 3111 from moving toward the notch of the mounting groove 111. This provides a relatively stable connection between the connecting portion 31 and the mounting base 11, and prevents the side brush 10 from falling off relative to the body 30.

[0116] See also Figures 5 to 8 In other embodiments, the second connecting portion 313 is provided with a second latching protrusion 3131 at the end away from the fuselage 30, and a second latching groove 11133 is provided in the second groove 1113. When the connecting portion 31 is installed in the installation groove 111, the second latching groove 11133 engages with the second latching protrusion 3131.

[0117] In this case, the second engaging portion 11131 need not be provided within the second groove 1113; instead, only the second engaging groove 11133 may be provided within the second groove 1113. The second engaging groove 11133 may be located at the bottom of the second groove 1113, with the sidewalls of the second engaging groove 11133 further away from the centerline of the mounting groove 111 than the sidewalls of the second groove 1113. As the connecting portion 31 extends into the mounting groove 111, the second engaging protrusion 3131 may be squeezed by the sidewalls of the second groove 1113, causing a certain deformation of the second connecting portion 313 toward the gap 315. After the second engaging protrusion 3131 enters the second engaging groove 11133, the second connecting portion 313 may return to its original shape, moving away from the gap. At this point, the second engaging protrusion 3131 is located within the second groove 1113. The top wall of the second slot 11133 can cooperate with the second protrusion 3131. When the side brush 10 encounters an obstacle and tends to separate from the connecting part 31, the top wall of the second slot 11133 can be used to prevent the second protrusion 3131 from moving toward the notch of the mounting slot 111, so that the connection between the connecting part 31 and the mounting seat 11 is more stable.

[0118] In this embodiment, the second groove 1113 has a relatively simple structure and is easy to manufacture. Furthermore, the cooperation between the second engaging groove 11133 and the second engaging protrusion 3131 effectively prevents the second engaging protrusion 3131 from moving toward the notch of the mounting groove 111. This provides a relatively stable connection between the connecting portion 31 and the mounting base 11, and prevents the side brush 10 from falling off relative to the body 30.

[0119] See also Figures 5 to 8In some other embodiments, the first connecting portion 311 is provided with a first latching protrusion 3111 at the end away from the fuselage 30, and a first latching groove 11113 is provided in the first groove 1111. When the connecting portion 31 is installed in the mounting slot 111, the first latching groove 11113 engages with the first latching protrusion 3111; the second connecting portion 313 is provided with a second latching protrusion 3131 at the end away from the fuselage 30, and a second latching groove 11133 is provided in the second groove 1113. When the connecting portion 31 is installed in the mounting slot 111, the second latching groove 11133 engages with the second latching protrusion 3131.

[0120] In this case, the first engaging portion 11111 and the second engaging portion 11131 are not provided in the mounting groove 111, resulting in a simpler structure and easier processing. Furthermore, the cooperation between the first engaging groove 11113 and the second engaging protrusion 3131, as well as the cooperation between the second engaging groove 11133 and the second engaging protrusion 3131, further prevents the connecting portion 31 from moving toward the notch of the mounting groove 111, thus further stabilizing the connection between the connecting portion 31 and the mounting base 11 and preventing the side brush 10 from falling off relative to the body 30.

[0121] See also Figures 5 to 8 In some embodiments, a first clearance groove 11115 is provided in the sidewall of the first groove 1111 facing the second groove 1113. The first clearance groove 11115 is recessed from the sidewall of the first groove 1111 in a direction away from the centerline of the mounting groove 111. The first clearance groove 11115 is provided near the notch of the mounting groove 111. In the width direction W from the first connecting portion 311 to the second connecting portion 313, the first clearance groove 11115 corresponds to the anti-slip portion 113.

[0122] As the connecting portion 31 extends into the mounting groove 111, the first clearance groove 11115 is used to accommodate the first latching protrusion 3111. In the width direction W, the distance between the sidewall of the first clearance groove 11115 and the anti-slip portion 113 may be greater than or equal to the width of the first connecting portion 311 at the location of the first latching protrusion 3111. This allows the first connecting portion 311 to smoothly extend into the gap between the first clearance groove 11115 and the anti-slip portion 113, pass through the gap between the first clearance groove 11115 and the anti-slip portion 113, and extend toward the bottom wall of the first groove 1111, ultimately engaging with the first engaging portion 11111 and / or the first latching groove 11113. If the first clearance groove 11115 is not provided in the first groove 1111, the gap between the bottom wall of the first groove 1111 and the anti-slip portion 113 is small, and the first connecting portion 311 is difficult to extend into the gap, so that the first connecting portion 311 is difficult to cooperate with the first locking portion 11111 and / or the first locking groove 11113.

[0123] See also Figures 5 to 8In other embodiments, a second clearance groove 11135 is provided in the sidewall of the second groove 1113 facing the first groove 1111. The second clearance groove 11135 is recessed from the sidewall of the second groove 1113 in a direction away from the centerline of the mounting groove 111. The second clearance groove 11135 is provided near the notch of the mounting groove 111. In the width direction W, the second clearance groove 11135 corresponds to the anti-slip portion 113.

[0124] As the connecting portion 31 extends into the mounting groove 111, the second clearance groove 11135 is used to accommodate the second latching protrusion 3131. In the width direction W, the distance between the sidewall of the second clearance groove 11135 and the anti-slip portion 113 can be greater than or equal to the width of the second connecting portion 313 at the location of the second latching protrusion 3131. This allows the second connecting portion 313 to smoothly extend into the gap between the second clearance groove 11135 and the anti-slip portion 113, pass through the gap between the second clearance groove 11135 and the anti-slip portion 113, and extend toward the bottom wall of the second groove 1113, ultimately engaging with the second engaging portion 11131 and / or the second latching groove 11133. If the second groove 11135 is not provided in the second groove 1113, the gap between the bottom wall of the second groove 1113 and the anti-slip portion 113 is small, and the second connecting portion 313 is difficult to extend into the gap, so that the second connecting portion 313 is difficult to cooperate with the second locking portion 11131 and / or the second locking groove 11133.

[0125] See also Figures 5 to 8 In some other embodiments, a first clearance groove 11115 is defined in the sidewall of the first slot 1111 facing the second slot 1113, and a second clearance groove 11135 is defined in the sidewall of the second slot 1113 facing the first slot 1111. In this manner, the first connecting portion 311 can smoothly extend into the gap between the first clearance groove 11115 and the anti-slip portion 113, and the second connecting portion 313 can smoothly extend into the gap between the second clearance groove 11135 and the anti-slip portion 113. As a result, the connecting portion 31 can smoothly extend toward the bottom of the mounting slot 111 to engage with the mounting base 11. This simplifies installation of the connecting portion 31 and the mounting base 11.

[0126] See also Figures 5 to 8In some embodiments, the first connecting portion 311 is provided with a first locking protrusion 3111 at the end away from the fuselage 30, and a first locking portion 11111 is provided in the first groove 1111. When the connecting portion 31 is installed in the mounting groove 111, the first locking portion 11111 is used to prevent the first locking protrusion 3111 from moving in the direction of leaving the mounting groove 111. A first clearance groove 11115 is provided on the side wall of the first groove 1111 facing the second groove 1113, and a first guide surface 11116 is provided at the bottom of the first clearance groove 11115. The first guide surface 11116 connects the first locking portion 11111 and the first clearance groove 11115. In the direction in which the connecting portion 31 is inserted into the mounting groove 111, the distance between the first guide surface 11116 and the center line of the mounting groove 111 gradually decreases.

[0127] During the insertion of the connecting portion 31 into the mounting slot 111, after the first latching protrusion 3111 enters the first clearance groove 11115, the first guide surface 11116 can engage with the first mating surface 3113, guiding the first latching protrusion 3111 toward the first engaging portion 11111. Preferably, the first guide surface 11116 and the first mating surface 3113 are substantially parallel, thereby effectively guiding the first latching protrusion 3111, ensuring mating between the first latching protrusion 3111 and the first engaging portion 11111. When the first latching protrusion 3111 is located below the first engaging portion 11111, the engagement of the first engaging surface 11112 and the first mating surface 3113 prevents the first latching protrusion 3111 from moving toward the notch of the mounting slot 111, thereby providing a more secure connection between the first connecting portion 311 and the mounting slot 111.

[0128] When the bottom wall of the first recess 11115 is provided with the first guide surface 11116, the structure of the first recess 1111 is relatively simple, and it can also guide the first connecting portion 311, so that the first latching protrusion 3111 can smoothly extend into the bottom of the first recess 1111. The user can easily install the side brush 10 without applying a large external force, providing a good user experience.

[0129] See also Figures 5 to 8In other embodiments, the second connecting portion 313 is provided with a second latching protrusion 3131 at the end away from the fuselage 30, and a second engaging portion 11131 is provided in the second groove 1113. When the connecting portion 31 is installed in the mounting groove 111, the second engaging portion 11131 is used to prevent the second latching protrusion 3131 from moving in the direction of leaving the mounting groove 111. A second clearance groove 11135 is provided on the side wall of the second groove 1113 facing the first groove 1111, and a second guide surface 11136 is provided at the bottom of the second clearance groove 11135. In the direction in which the connecting portion 31 is inserted into the mounting groove 111, the distance between the second guide surface 11136 and the center line of the mounting groove 111 gradually decreases.

[0130] During the insertion of the connecting portion 31 into the mounting slot 111, after the second latching protrusion 3131 enters the second clearance groove 11135, the second guide surface 11136 can engage with the second mating surface 3133, guiding the second latching protrusion 3131 toward the second engaging portion 11131. Preferably, the second guide surface 11136 and the second mating surface 3133 are substantially parallel, thereby effectively guiding the second latching protrusion 3131 and ensuring engagement between the second latching protrusion 3131 and the second engaging portion 11131. When the second latching protrusion 3131 is positioned below the second engaging portion 11131, the engagement of the second engaging surface 11132 and the second mating surface 3133 prevents the second latching protrusion 3131 from moving toward the notch of the mounting slot 111, thereby providing a more secure connection between the second connecting portion 313 and the mounting slot 111.

[0131] When the second guide surface 11136 is provided on the bottom wall of the second recess 11135, the structure of the second recess 1113 is relatively simple, and the second connecting portion 313 can be guided so that the second latching protrusion 3131 can smoothly extend into the bottom of the second recess 1113. The user can easily install the side brush 10 without applying a large external force, providing a good user experience.

[0132] See also Figures 5 to 8In some other embodiments, the first connecting portion 311 is provided with a first locking protrusion 3111 at the end away from the fuselage 30, and a first engaging portion 11111 is provided in the first groove 1111. When the connecting portion 31 is installed in the mounting groove 111, the first engaging portion 11111 is used to prevent the first locking protrusion 3111 from moving in the direction of leaving the mounting groove 111. A first clearance groove 11115 is provided on the side wall of the first groove 1111 facing the second groove 1113. A first guide surface 11116 is provided at the bottom of the first clearance groove 11115. The first guide surface 11116 connects the first locking portion 11111 and the first clearance groove 11115. In the direction in which the connecting portion 31 is inserted into the mounting groove 111, the first guide surface 111 16 and the distance between the center line of the installation slot 111 gradually decreases; the second connecting portion 313 is provided with a second latching protrusion 3131 at the end away from the fuselage 30, and a second engaging portion 11131 is provided in the second groove 1113. When the connecting portion 31 is installed in the installation slot 111, the second engaging portion 11131 is used to prevent the second latching protrusion 3131 from moving in the direction of leaving the installation slot 111. A second makeshift groove 11135 is provided on the side wall of the second groove 1113 facing the first groove 1111, and a second guide surface 11136 is provided at the bottom of the second makeshift groove 11135. In the direction in which the connecting portion 31 is inserted into the installation slot 111, the distance between the second guide surface 11136 and the center line of the installation slot 111 gradually decreases.

[0133] When the bottom wall of the first clearance groove 11115 is provided with a first guide surface 11116, the structure of the first groove 1111 is relatively simple, and it can also guide the first connecting portion 311, so that the first latching protrusion 3111 can smoothly extend into the bottom of the first groove 1111. When the bottom wall of the second clearance groove 11135 is provided with a second guide surface 11136, the structure of the second groove 1113 is also relatively simple, and it can also guide the second connecting portion 313, so that the second latching protrusion 3131 can smoothly extend into the bottom of the second groove 1113. The user's operation when installing the side brush 10 is relatively simple, and no significant external force is required, providing a good user experience.

[0134] See also Figures 5 to 8In some embodiments, the first latching protrusion 3111 cooperates with the first engaging portion 11111 in the first groove 1111, and / or the first latching protrusion 3111 cooperates with the first latching groove 11113 located in the first groove 1111. In one embodiment, the first latching protrusion 3111 can cooperate with the first latching portion 11111 to prevent the connection portion 31 from moving toward the notch of the installation groove 111. In another embodiment, the first latching protrusion 3111 can cooperate with the first latching groove 11113 to prevent the connection portion 31 from moving toward the notch of the installation groove 111. In yet another embodiment, the first latching protrusion 3111 can cooperate with both the first latching portion 11111 and the first latching groove 11113 to prevent the connection portion 31 from moving toward the notch of the installation groove 111.

[0135] See also Figures 6 to 9 In some embodiments, when a first clearance groove 11115 is provided on the side wall of the first groove 1111 facing the second groove 1113, in the direction in which the connecting portion 31 is inserted into the installation groove 111, the length h1 of the anti-slip portion 113, the depth d1 of the first clearance groove 11115, and the height h2 of the first latch 3111 satisfy the relationship: h1≤d1-h2.

[0136] When the length h1 of the anti-slip portion 113 is less than or equal to the depth d1 of the first clearance groove 11115 minus the height h2 of the first latching protrusion 3111, when the first latching protrusion 3111 located at the bottom of the first clearance groove 11115 contacts the first engaging portion 11111, the first latching protrusion 3111 will be squeezed by the first engaging portion 11111. At this time, in the width direction W, the first latching protrusion 3111 does not correspond to the anti-slip portion 113, so that the first latching protrusion 3111 can be deformed toward the direction of the gap 315 under the action of the extrusion force, so that the connecting portion 31 can continue to extend downward into the installation groove 111.

[0137] If the length h1 of the anti-slip portion 113 is greater than the depth d1 of the first clearance groove 11115 minus the height h2 of the first latching protrusion 3111, when the first latching protrusion 3111 at the bottom of the first clearance groove 11115 contacts and is squeezed by the first engaging portion 11111, at least a portion of the first latching protrusion 3111 still corresponds to the anti-slip portion 113 in the width direction W. At this time, the first latching protrusion 3111 tends to deform toward the gap 315 under the action of the squeezing force, but the anti-slip portion 113 prevents the first connecting portion 311 from deforming toward the gap 315. The first latching protrusion 3111 cannot deform sufficiently toward the gap 315, and the first latching protrusion 3111 becomes stuck between the first engaging portion 11111 and the anti-slip portion 113, making it difficult for the connecting portion 31 to continue extending downward into the mounting groove 111, and thus making it difficult for the connecting portion 31 to engage with the mounting seat 11.

[0138] See also Figures 5 to 8 In some embodiments, the second connecting portion 313 is provided with a second latching protrusion 3131 at the end away from the body 30. The second latching protrusion 3131 cooperates with the second engaging portion 11131 in the second slot 1113, and / or the second latching protrusion 3131 cooperates with the second latching slot 11133 located in the second slot 1113. In one embodiment, the second latching protrusion 3131 can cooperate with the second engaging portion 11131 to prevent the connecting portion 31 from moving toward the notch of the mounting slot 111. In another embodiment, the second latching protrusion 3131 can cooperate with the second latching slot 11133 to prevent the connecting portion 31 from moving toward the notch of the mounting slot 111. In yet another embodiment, the second latching protrusion 3131 can cooperate with both the second engaging portion 11131 and the second latching slot 11133 to prevent the connecting portion 31 from moving toward the notch of the mounting slot 111.

[0139] See also Figures 6 to 9 In some embodiments, when a second clearance groove 11135 is provided on the side wall of the second groove 1113 facing the first groove 1111, in the direction in which the connecting portion 31 is inserted into the installation groove 111, the height h1 of the anti-slip portion 113, the depth d2 of the second clearance groove 11135, and the height h3 of the second latch 3131 satisfy the relationship: h1≤d2-h3.

[0140] When the length h1 of the anti-slip portion 113 is less than or equal to the depth d2 of the second clearance groove 11135 minus the height h3 of the second latching protrusion 3131, when the second latching protrusion 3131 located at the bottom of the second clearance groove 11135 contacts the second engaging portion 11131, the second latching protrusion 3131 will be squeezed by the second engaging portion 11131. At this time, in the width direction W, the second latching protrusion 3131 does not correspond to the anti-slip portion 113, so that the second latching protrusion 3131 can be deformed toward the direction of the gap 315 under the action of the extrusion force, so that the connecting portion 31 can continue to extend downward into the mounting groove 111.

[0141] If the length h1 of the anti-slip portion 113 is greater than the depth d2 of the second clearance groove 11135 minus the height h3 of the second latching protrusion 3131, when the second latching protrusion 3131 at the bottom of the second clearance groove 11135 contacts and is squeezed by the second engaging portion 11131, at least a portion of the second latching protrusion 3131 still corresponds to the anti-slip portion 113 in the width direction W. At this time, the second latching protrusion 3131 tends to deform toward the gap 315 under the action of the squeezing force, but the anti-slip portion 113 prevents the second connecting portion 313 from deforming toward the gap 315. Therefore, the second latching protrusion 3131 cannot deform sufficiently toward the gap 315 and becomes stuck between the second engaging portion 11131 and the anti-slip portion 113. This makes it difficult for the connecting portion 31 to continue extending downward into the mounting groove 111, and it is difficult for the connecting portion 31 to form an engagement with the mounting seat 11.

[0142] See also Figure 1 and Figure 2 In some embodiments, the side brush 10 includes at least two brush bar assemblies 13, each of which includes a first connecting arm 131, a second connecting arm 133, and bristles 135. The first connecting arm 131, the second connecting arm 133, and the bristles 135 are sequentially connected, and the end of the first connecting arm 131 away from the second connecting arm 133 is connected to the mounting base 11. The first connecting arm 131 has a greater hardness than the second connecting arm 133. When the first connecting arm 131 is connected to the mounting base 11, the first connecting arm 131 is harder than the second connecting arm 133. When it comes into contact with an obstacle, the first connecting arm 131 is not easily deformed or bent. The first connecting arm 131 can rotate with the second connecting arm 133 and the bristles 135, and the first connecting arm 131 is not easily bent when rotating with the second connecting arm 133 and the bristles 135. When the first connecting arm 131 is relatively hard and not easily deformed or bent, an obstacle acts on the first connecting arm 131, causing the first connecting arm 131 to move upward. Since the first connecting arm 131 has a certain length, the torque generated by the force of the obstacle is relatively large, and the side of the mounting base 11 opposite the first connecting arm 131 is more likely to disengage from the connecting portion 31, thereby easily causing the side brush 10 to fall off relative to the body 30. When the first connecting arm 131 is relatively hard, providing the anti-detachment portion 113 in the mounting groove 111 has a better anti-detachment effect.

[0143] Specifically, the brush bar assembly 13 is designed to directly contact the surface to be cleaned. When the connection portion 31 drives the mounting base 11 to rotate, the mounting base 11 can also drive the brush bar assembly 13 to rotate, so that the bristles 135 in the brush bar assembly 13 can sweep dirt from the surface to the suction port, where it can be sucked into the dust box by the fan. The number of brush bar assemblies 13 in the side brush 10 includes, but is not limited to, two, three, four, or more. The side brush 10 of the present application includes two brush bar assemblies 13.

[0144] When the hardness of the first connecting arm 131 is greater than that of the second connecting arm 133, the connection between the brush bar assembly 13 and the mounting base 11 is more stable. When the mounting base 11 drives the brush bar assembly 13 to rotate, the brush bar assembly 13 is less likely to fall off relative to the mounting base 11. To ensure connection with the mounting base 11, the first connecting arm 131 can typically be shaped. Therefore, the first connecting arm 131 can be manufactured using an injection molding process.

[0145] The second connecting arm 133 can fix the bristles 135. At the same time, the second connecting arm 133 can also extend the overall distance of the brush bar assembly 13, so that the cleaning range of the brush bar assembly 13 is larger. Generally, the bristles 135 and the second connecting arm 133 are both slender and have a generally consistent extension trend. In other embodiments, the brush bar assembly 13 can also omit the second connecting arm 133 and directly connect the bristles 135 to the first connecting arm 131. Each bristle 135 generally has multiple filaments, and the multiple filaments diverge from the root connected to the first connecting arm 131 or the second connecting arm 133 to the end. For each filament, the filament can be straight; or the end of the filament can be bent backward relative to the rotation direction during normal cleaning; or the end of the filament can be bent toward the ground.

[0146] See also Figure 1 and Figure 2 In some embodiments, the material of the first connecting arm 131 is the same as that of the mounting base 11; and / or, the second connecting arm 133 is made of an elastic material; and / or, at least one of the at least two brush bar assemblies 13 is a movable brush bar assembly 13, and the movable brush bar assembly 13 can move between a first position and a second position.

[0147] For example, the mounting base 11 and the first connecting arm 131 can both be made of hard rubber or hard plastic. When the mounting base 11 and the first connecting arm 131 are made of the same material, the brush strip assembly 13 has a high degree of adaptability when connected to the mounting base 11, the connection between the brush head assembly and the mounting base 11 is relatively stable, and the brush strip assembly 13 is not easy to fall off relative to the mounting base 11. The material of the second connecting arm 133 can be thermoplastic polyurethane elastomer (TPU). In this case, the second connecting arm 133 can have a certain degree of elasticity and softness, and the second connecting arm 133 can increase the flexibility of the brush strip assembly 13. When the brush strip assembly 13 collides with an obstacle during rotation, the problem of the second connecting arm 133 breaking can be avoided, and the service life of the brush strip assembly 13 is extended.

[0148] The movable brush bar assembly 13 is rotatable relative to the mounting base 11 to switch between a first position and a second position. In the first position, the movable brush bar assembly 13 is separated from adjacent brush bar assemblies 13 and spaced apart from each other. In the second position, the movable brush bar assembly 13 is closed to adjacent brush bar assemblies 13 and positioned close to each other.

[0149] See also Figure 1 and Figure 2 In one embodiment, of the two brush bar assemblies 13 in the side brush 10, one is a movable brush bar assembly 13 and the other is a fixed brush bar assembly 13. The fixed brush bar assembly 13 remains in a fixed position relative to the mounting base 11. The fixed brush bar assembly 13 is adjacent to the movable brush bar assembly 13. Movement of the movable brush bar assembly 13 between the first position and the second position causes the movable brush bar assembly 13 and the fixed brush bar assembly 13 to move closer to or further away from each other.

[0150] For example, when the movable brush bar assembly 13 is in the first position, the angle between the bristles 135 of the movable brush bar assembly 13 and the bristles 135 of the adjacent fixed brush bar assembly 13 can range from 120° to 165°. This allows the multiple brush bar assemblies 13 to be more dispersed, achieving a better cleaning effect. For example, when the movable brush bar assembly 13 is in the first position, the angle between the bristles 135 of the movable brush bar assembly 13 and the bristles 135 of the fixed brush bar assembly 13 can be 150°. For example, when the movable brush bar assembly 13 is in the second position, the angle between the bristles 135 of the movable brush bar assembly 13 and the bristles 135 of the fixed brush bar assembly 13 can range from 0° to 20°, which further facilitates untangling. For example, when the movable brush bar assembly 13 is in the second position, the angle between the bristles 135 of the movable brush bar assembly 13 and the bristles 135 of the fixed brush bar assembly 13 can be 15°. Exemplarily, the force that moves the movable brush bar assembly 13 may come from one or more of a driving source such as a motor or a hydraulic device, friction between the brush bar assembly 13 and the surface to be cleaned, inertia, etc. Those skilled in the art may reasonably select one or more of the above methods as needed. In other embodiments, the side brush 10 may include at least two adjacent movable brush bar assemblies 13. Exemplarily, the side brush 10 may have two brush bar assemblies 13, and both brush bar assemblies 13 are movable brush bar assemblies 13. Alternatively, the side brush 10 has more than two brush bar assemblies 13, one of the brush bar assemblies 13 adjacent to one of the movable brush bar assemblies 13 is a movable brush bar assembly 13, and the remaining brush bars are fixed brush bar assemblies 13. Alternatively, the side brush 10 has more than two brush bar assemblies 13, and both brush bar assemblies 13 adjacent to one of the movable brush bar assemblies 13 are movable brush bar assemblies 13.

[0151] When performing cleaning tasks, long filamentous garbage may be entangled on the multiple brush bar assemblies 13, and it is difficult for the long filamentous garbage to break away from the brush bar assemblies 13 under the negative pressure of the fan. Moreover, when the side brush 10 cleans the surface to be cleaned, the spacing between the multiple brush bar assemblies 13 is large. Once the long filamentous garbage is entangled on multiple brush bar assemblies 13 at the same time, it will be more difficult for it to break away automatically. However, at least a portion of the multiple brush bar assemblies 13 provided in the present disclosure are movable brush bar assemblies 13. During the process of the movable brush bar assembly 13 moving from the first position to the second position, that is, during the process of the movable brush bar assembly 13 and at least one of the adjacent brush bar assemblies 13 moving from the separated state to the closed state, the spacing between the free ends of the multiple brush bar assemblies 13 becomes significantly smaller than when the movable brush bar assembly 13 is in the first position. Therefore, if filamentary debris is entangled in both the movable brush bar assembly 13 and the fixed brush bar assembly 13, the free ends of the two brush bar assemblies approach each other, allowing the filamentary debris to be easily dislodged. Alternatively, the movable brush bar assembly 13 can be switched back and forth between the first and second positions, causing the movable brush bar assembly 13 and the fixed brush bar assembly 13 to continuously move closer, further away, closer, further away, etc. This can cause the filamentary debris to continuously loosen, tighten, loosen, tighten, loosen, etc. on the side brush 10, allowing the filamentary debris to be easily dislodged. This process can be referred to as disentanglement. Based on this, a cleaning device using the side brush 10 can have a disentanglement mode.

[0152] See also Figures 3 to 5 In some embodiments, a guide surface 1115 is provided around the periphery of the notch of the mounting groove 111. In the direction in which the connector is inserted into the mounting groove 111, the distance between the guide surface 1115 and the centerline of the mounting groove 111 gradually decreases. The guide surface 1115 is used to guide the connecting portion 31 so that the connecting portion 31 can accurately enter the mounting groove 111. Specifically, the guide surface 1115 is used to cooperate with the first mating surface 3113 of the first latching protrusion 3111 to guide the first connecting portion 311 accurately into the first groove 1111. The guide surface 1115 is used to cooperate with the second mating surface 3133 of the second latching protrusion 3131 to guide the second connecting portion 313 accurately into the second groove 1113.

[0153] See also Figures 3 to 5In some embodiments, the mounting base 11 includes a base body 115 and a loading portion 117. The loading portion 117 is disposed on a side of the base body 115 close to the body 30 and is provided with a mounting groove 111. The loading portion 117 is configured to connect to the connecting portion 31 so that the side brush 10 is securely connected to the body 30. The base body 115 is configured to mount the brush bar assembly 13. The loading portion 117 and the base body 115 are fixedly connected. When the connecting portion 31 drives the loading portion 117 to rotate, the loading portion 117 drives the base body 115 to rotate, and the base body 115 drives the brush bar assembly 13 to rotate, thereby enabling the brush bar assembly 13 to clean the surface to be cleaned.

[0154] See also Figure 10 The embodiment of the present application provides a base station 300, which is used in conjunction with the cleaning robot 100 of the above embodiment. The base station 300 includes a docking position for accommodating the cleaning robot 100. The base station 300 can be used to power the cleaning device and clean it.

[0155] In the base station 300 according to the embodiment of the present application, the mounting base 11 and the connecting portion 31 can be connected by a snap fit. When the mounting base 11 and the connecting portion 31 are connected, the first connecting portion 311 is located within the first groove 1111, the second connecting portion 313 is located within the second groove 1113, and the anti-slip portion 113 is located between the first connecting portion 311 and the second connecting portion 313. If the side brush 10 rubs against an obstacle and is subjected to a downward force, and the mounting base 11 tends to separate from the connecting portion 31, the anti-slip portion 113 can prevent the first connecting portion 311 and the second connecting portion 313 from significantly deforming toward the gap 315, thereby preventing the connecting portion 31 and the mounting base 11 from being disengaged. This provides a more stable connection between the connecting portion 31 and the mounting base 11, making it less likely that the mounting base 11 will fall off relative to the connecting portion 31, and thus the side brush 10 will be less likely to fall off relative to the body 30.

[0156] See also Figure 10 An embodiment of the present application provides a cleaning system 1000, which includes the cleaning robot 100 and a base station 300 of the above embodiment. The base station 300 is used to cooperate with the cleaning robot 100 of the above embodiment, and the base station 300 includes a docking position for accommodating the cleaning robot 100.

[0157] In the cleaning system 1000 according to the embodiment of the present application, the mounting base 11 and the connecting portion 31 can be connected by a snap fit. When the mounting base 11 and the connecting portion 31 are connected, the first connecting portion 311 is located within the first groove 1111, the second connecting portion 313 is located within the second groove 1113, and the anti-slip portion 113 is located between the first connecting portion 311 and the second connecting portion 313. If the side brush 10 rubs against an obstacle and is subjected to a downward force, and the mounting base 11 tends to separate from the connecting portion 31, the anti-slip portion 113 can prevent the first connecting portion 311 and the second connecting portion 313 from significantly deforming toward the gap 315, thereby preventing the connecting portion 31 and the mounting base 11 from being disengaged. This provides a more stable connection between the connecting portion 31 and the mounting base 11, making it less likely that the mounting base 11 will fall off the connecting portion 31, and thus the side brush 10 will be less likely to fall off the body 30.
