[0052] In order to better understand the above-mentioned technical scheme, the technical scheme of the embodiments of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0053] The first aspect of an embodiment of the present application proposes a damper 100, comprising: a first connecting member 110, on which a first guide surface 111 is formed; a second connecting member 120, on which a second guide surface 121 is formed, and the second guide surface 121 is used to abut against the first guide surface 111; a reset member 130, which is connected to the second connecting member 120, and when the second connecting member 120 rotates relative to the first connecting member 110, the reset member 130 is used to apply a reset force to the second connecting member 120.

[0054] The damper 100 provided in the embodiment of the present application includes a first connecting member 110, a second connecting member 120 and a reset member 130. The first connecting member 110 and the second connecting member 120 are respectively formed with a first guide surface 111 and a second guide surface 121. During use, when providing damping for two objects capable of relative motion, one of the first connecting members 110 is connected to one object, and the second connecting member 120 is connected to the other object. For example, when the damper 100 is applied to a base station, the first connecting member 110 is connected to the base station body 210, and the second connecting member 120 is connected to the reset member 130. The second connecting member 120 is connected to the hatch 220. When the hatch 220 rotates relative to the base station body 210, the first connecting member 110 rotates relative to the second connecting member 120. In this process, the first guide surface 111 and the second guide surface 121 guide the movement between the first connecting member 110 and the second connecting member 120, so that the second connecting member 120 compresses the reset member 130 and drives the reset member 130 to twist. In this case, the reset member 130 can apply reverse stress, thereby providing resistance to the opening of the hatch 220, and a damping effect can be achieved. When the damper 100 provided in the embodiment of the present application is applied to the base station, it can slow down the speed of opening the hatch 220, reduce the probability of collision between the hatch 220 and other components, and reduce the noise of opening the hatch 220.

[0055] It can be understood that, taking the application of the damper 100 on the base station as an example, when the hatch 220 is closed, the first connecting member 110 and the second connecting member 120 also rotate relative to each other, the first guide surface 111 and the second guide surface 121 are guided, and the reset member 130 is reset, which can facilitate the closing of the hatch 220, making the closing of the hatch 220 more labor-saving, more convenient to use, and more advanced.

[0056] It can be understood that during the assembly process of the damper 100 provided in the embodiment of the present application, it is only necessary to connect the first connecting member 110 and the second connecting member 120 to two relatively moving objects respectively to provide a damping effect. There is no need for a fixed connection relationship between the first connecting member 110 and the second connecting member 120, and the requirements for assembly accuracy between the two are not high, so it is easy to assemble. At the same time, the reset member 130 is used as the power component of the damping, which has a lower failure rate.

[0057] like Figures 3 to 6 As shown, in a feasible embodiment, the damper 100 also includes: a countersunk hole 140 and a boss 150, one of the countersunk hole 140 and the boss 150 is opened on the first connecting member 110, and the other is opened on the second connecting member 120, and the boss 150 is used to be inserted into the countersunk hole 140.

[0058] In this technical solution, the damper 100 may further include a countersunk hole 140 and a boss 150. The boss 150 is received in the countersunk hole 140. On the one hand, the first connecting member 110 and the second connecting member 120 can have a plug-in relationship. Through the plug-in of the boss 150 and the countersunk hole 140, when the damper 100 is assembled, it is more convenient to accurately assemble the damper 100. For example, when the boss 150 is completely inserted into the countersunk hole 140, it can be shown that the damper 100 is assembled in place, making the assembly of the damper 100 more convenient. On the other hand, through the countersunk hole 140 and the boss 1 The setting of 50 limits the freedom between the first connecting member 110 and the second connecting member 120. The first connecting member 110 and the second connecting member 120 can rotate relative to each other and can move along the length direction of the boss 150. With this setting, when the first connecting member 110 rotates relative to the second connecting member 120, the reset member 130 can be compressed, stretched or twisted to provide damping. At the same time, the freedom of other aspects can be limited, which can reduce the probability of misalignment of the first connecting member 110 and the second connecting member 120, thereby ensuring the stability of the damper 100.

[0059] like Figures 3 to 6 As shown, in a feasible implementation manner, the boss 150 is disposed on the second connecting member 120 , and the counterbore 140 is opened on the first connecting member 110 .

[0060] In this technical solution, the setting positions of the boss 150 and the countersunk hole 140 are further clarified. The boss 150 is set on the second connecting member 120, and the countersunk hole 140 is opened on the first connecting member 110. This setting is based on the consideration that since the second connecting member 120 is connected to the reset member 130, the structure and connection relationship of the first connecting member 110 are simpler than those of the second connecting member 120. Therefore, arranging the boss 150 on the second connecting member 120 can make the positioning between the first connecting member 110 and the second connecting member 120 more precise.

[0061] like Figures 3 to 6 As shown, in a feasible embodiment, the damper 100 also includes: a first limit member 160, which is arranged on the first connecting member 110; and a second limit member 170, which is arranged on the second connecting member 120; wherein the first limit member 160 is used to abut against the second limit member 170 to limit the rotation angle of the second connecting member 120 relative to the first connecting member 110.

[0062] In this technical solution, the damper 100 may also include a first limit member 160 and a second limit member 170. When the first connecting member 110 and the second connecting member 120 are rotated to the extreme positions, the first limit member 160 may abut against the second limit member 170. Based on this, the rotation angle of the second connecting member 120 relative to the first connecting member 110 can be limited, thereby preventing the first connecting member 110 from excessively rotating relative to the second connecting member 120.

[0063] Taking the application of the damper 100 on the base station as an example, the opening of the cabin door 220 can be controlled by setting the first limit member 160 and the second limit member 170 on the damper 100. When the cabin door 220 rotates to the maximum design width, it will not be able to continue to rotate. The base station does not need to be equipped with other limit components or detection components, and the maximum opening of the cabin door 220 can be accurately controlled, which is more convenient to use. The opening of the cabin door 220 can be limited by abutting two mechanical structures, which is lower in cost.

[0064] like Figure 7 As shown, in a feasible implementation manner, the damper 100 further includes: a fixing member 180 , a cavity is formed in the fixing member 180 , a portion of the second connecting member 120 is disposed in the cavity, and the second connecting member 120 can slide relative to the fixing member 180 .

[0065] In this technical solution, the damper 100 may further include a fixing member 180. This configuration is based on the consideration that the second connecting member 120 needs to have a connection relationship with the reset member 130, and also needs to have an abutment relationship with the first connecting member 110, and may also have a plug-in connection relationship with the first connecting member 110. Therefore, the connection relationship of the second connecting member 120 is relatively complicated. The configuration of the fixing member 180 can provide an installation position for the second connecting member 120, facilitate the assembly of the second connecting member 120, and facilitate the reliable connection between the second connecting member 120 and other devices, thereby enabling the damper 100 to operate stably.

[0066] like Figures 1 to 7 As shown, in a feasible implementation manner, the first guide surface 111 and the second guide surface 121 are inclined surfaces.

[0067] In this technical solution, the styles of the first guide surface 111 and the second guide surface 121 are further provided. The first guide surface 111 and the second guide surface 121 are inclined surfaces. When the first connecting member 110 and the second connecting member 120 generate relative rotation, the first connecting member 110 and the second connecting member 120 can generate displacement in the axial direction. Based on this, reverse stress can be applied to the reset member 130, thereby achieving the damping effect of the damper 100. Through the setting of the inclined surface, it is convenient to control the deformation amount of the reset member 130, so that the damper 100 can achieve the damping effect.

[0068] It is understandable that the first guide surface 111 and the second guide surface 121 may also be curved surfaces, as long as the first connecting member 110 and the second connecting member 120 can be displaced in the axial direction when the first connecting member 110 and the second connecting member 120 rotate relative to each other.

[0069] like Figures 1 to 7 As shown, in a feasible implementation, the reset member 130 includes a spring. In this configuration, the spring can output reverse stress by being compressed, stretched or twisted, thereby achieving a damping effect, and the cost is lower by using the spring as a power component.

[0070] In a feasible implementation, the reset member 130 includes an elastic body made of elastic material. In this configuration, when the first connecting member 110 and the second connecting member 120 rotate relative to each other, the reset member 130 will also be compressed, stretched or twisted, and reverse stress can also be applied.

[0071] like Figures 8 to 11 As shown, according to the second aspect of an embodiment of the present application, a base station is proposed, comprising: a base station body 210; a hatch 220, the hatch 220 being hinged to the base station body 210; and a damper 100 such as any of the above-mentioned technical solutions, one of the first connecting member 110 and the second connecting member 120 being connected to the hatch 220, and the other being connected to the base station body 210.

[0072] The base station provided in the embodiment of the present application includes the damper 100 of any of the above technical solutions, so the base station has all the beneficial effects of the damper 100 of the above technical solutions.

[0073] The base station provided in the embodiment of the present application includes a base station body 210 and a hatch 220. The base station can be used on a cleaning system, and the base station can be used to store a cleaning device body, such as a sweeping robot. When there is no need to replace the dust bag of the base station or to clean the dust collection bin 211, the hatch 220 can be locked on the base station body 210 by a locking member to close the dust collection bin 211 on the base station body 210. In this case, the hatch 220 is a plane, the base station is more tidy, and the appearance of the hatch 220 can be adapted to the style of the user's home decoration, which can make the base station more beautiful. When the dust bag needs to be replaced or the dust collection bin 211 needs to be cleaned, the hatch 220 can be unlocked, and the hatch 220 opens the dust collection bin 211 to expose it, and the user can replace and clean the dust bag or clean the dust collection bin 211. Through the base station provided in the embodiment of the present application, the dust bag in the dust collection bin 211 can be replaced or cleaned only by opening the hatch 220. The space required to open the hatch 220 is very small, which can save opening and closing space and save user home decoration space. In addition, the user can open and close the hatch 220 with one hand, which makes the operation simpler and the user experience better.

[0074] The base station provided in the embodiment of the present application includes a damper 100, and the damper 100 includes a first connecting member 110, a second connecting member 120 and a reset member 130. The first connecting member 110 and the second connecting member 120 are respectively provided with a first guide surface 111 and a second guide surface 121. When the hatch 220 rotates relative to the base station body 210, the first connecting member 110 rotates relative to the second connecting member 120. During this process, the first guide surface 111 and the second guide surface 121 guide the movement between the first connecting member 110 and the second connecting member 120, so that the second connecting member 120 compresses the reset member 130. In this case, the reset member 130 can provide a time-reverse stress, thereby providing resistance to the opening of the hatch 220, thereby achieving a damping effect. When the damper 100 provided in the embodiment of the present application is applied to a base station, it can slow down the opening speed of the hatch 220, reduce the probability of the hatch 220 colliding with other components, and reduce the noise of opening the hatch 220; and the damper 100 provided in the embodiment of the present application has a simple structure and is easy to assemble.

[0075] like Fig.10 and Fig.11 As shown, in a feasible implementation, the second connecting member 120 is connected to the hatch 220, and the first connecting member 110 is connected to the base station body 210. This configuration is made in consideration that the second connecting member 120 needs to be connected to the reset member 130, so the connection relationship of the second connecting member 120 is more complicated than that of the first connecting member 110. Connecting the second connecting member 120 to the hatch 220 of a relatively smaller volume facilitates the assembly of the damper 100.

[0076] In a feasible implementation manner, the second connecting member 120 is connected to the cabin door 220 via a fixing member 180 .

[0077] In this technical solution, the second connecting member 120 is connected to the cabin door 220 through the fixing member 180. This arrangement is based on the consideration that the second connecting member 120 needs to have a connection relationship with the reset member 130, and also needs to have an abutting relationship with the first connecting member 110, and may also have a plug-in connection relationship with the first connecting member 110. Therefore, the connection relationship of the second connecting member 120 is relatively complicated. The setting of the fixing member 180 can provide an installation position for the second connecting member 120. The fixing member 180 can be connected to the door body, which is convenient for the second connecting member 120 to be assembled in place, and to facilitate the reliable connection between the second connecting member 120 and the cabin door 220, thereby making the damper 100 work stably.

[0078] In some examples, in order to improve mechanical strength, the fixing member 180 and the door 220 may be an integrated structure.

[0079] According to a third aspect of an embodiment of the present application, a cleaning system is proposed, comprising: a damper 100 as in any of the above technical solutions; and / or a base station as in any of the above technical solutions.

[0080] The cleaning system provided in the embodiment of the present application includes the damper 100 and / or the base station of any of the above-mentioned technical solutions, so the cleaning system has all the beneficial effects of the damper 100 and / or the base station of the above-mentioned calculation solution.

[0081] The damper 100 of the cleaning system provided in the embodiment of the present application includes a first connecting member 110, a second connecting member 120 and a reset member 130. The first connecting member 110 and the second connecting member 120 are respectively provided with a first guide surface 111 and a second guide surface 121. The first connecting member 110 is connected to the base station body 210, and the second connecting member 120 is connected to the cabin door 220. When the cabin door 220 rotates relative to the base station body 210, the first connecting member 110 rotates relative to the second connecting member 120. During this process, the first guide surface 111 and the second guide surface 121 guide the movement between the first connecting member 110 and the second connecting member 120, so that the second connecting member 120 compresses the reset member 130 and drives the reset member 130 to twist. In this case, the reset member 130 can provide time-reverse stress, thereby providing resistance to the opening of the cabin door 220, thereby achieving a damping effect. When the damper 100 provided in the embodiment of the present application is applied to a base station, it can slow down the opening speed of the hatch 220, reduce the probability of the hatch 220 colliding with other components, and reduce the noise of opening the hatch 220; and the damper 100 provided in the embodiment of the present application has a simple structure and is easy to assemble.
