[0015] The beneficial effects of this utility model embodiment are as follows: Unlike existing technologies, this utility model embodiment provides a cleaning base station, including a base, a guide plate, a cleaning tank, and a support. The guide plate has a guide surface. The cleaning tank is located on the base and has a walking bridge for the auxiliary wheels of the cleaning robot to move. The support is detachably mounted on the cleaning tank, and the guide surface, walking bridge, and support are arranged sequentially along a first direction. The auxiliary wheels of the cleaning robot can travel to the support sequentially via the guide surface and the walking bridge. For cleaning robots with rear-mounted omnidirectional wheels or front and rear dual omnidirectional wheels, the rear-mounted omnidirectional wheels of the cleaning robot can move to a predetermined position via the guide surface, walking bridge, and support. This allows the cleaning robot's mopping components to be better positioned in the cleaning tank after entering the cleaning base station, with the rear-mounted omnidirectional wheels positioned on the support. When the mopping components are being cleaned in the cleaning tank, the possibility of the rear-mounted omnidirectional wheels interfering with other components is reduced. Furthermore, the bracket is detachably mounted in the cleaning tank, which facilitates easy installation and disassembly. When the cleaning base station is adapted to a cleaning robot with rear-mounted omnidirectional wheels or front and rear dual omnidirectional wheels, the bracket can be mounted in the cleaning tank. When the cleaning base station is adapted to a cleaning robot with only front-mounted omnidirectional wheels, the bracket can be detached from the cleaning tank, allowing the cleaning base station to be compatible with various types of cleaning robots. Therefore, the cleaning base station of this application can be compatible with both rear-mounted omnidirectional wheels and front and rear dual omnidirectional wheels. Attached Figure Description

[0027] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0028] Most existing cleaning robots only have front-mounted omnidirectional wheels, and the cleaning tanks of cleaning base stations mostly only support cleaning robots with front-mounted omnidirectional wheels, and cannot simultaneously accommodate cleaning robots with rear-mounted omnidirectional wheels or both front and rear omnidirectional wheels. The cleaning base station of this application can simultaneously accommodate cleaning robots with rear-mounted omnidirectional wheels or both front and rear omnidirectional wheels. To facilitate the reader's understanding of the inventive concept of this utility model, the specific structure of the cleaning base station is described below:

[0029] Please see Figures 1 to 3 The cleaning base station 100 includes a base 1, a guide plate 2, a cleaning tank 3, and a support 4. The guide plate 2 is provided with a guide surface 21. The cleaning tank 3 is located on the base 1 and is provided with a walking bridge 32 for the auxiliary wheels 202 of the cleaning robot 200 to move. The support 4 is detachably mounted on the cleaning tank 3 and is used for the auxiliary wheels 202 of the cleaning robot 200 to stop. The support 4 extends in the direction away from the guide surface 21 from the walking bridge 32. The guide surface 21, the walking bridge 32, and the support 4 are arranged sequentially along a first direction X. The auxiliary wheels 202 of the cleaning robot 200 can travel to the support 4 sequentially via the guide surface 21 and the walking bridge 32. The auxiliary wheels 202 can be omnidirectional wheels, driven wheels, or wheels with a driving function. For cleaning robots 200 with rear omnidirectional wheels or front and rear dual omnidirectional wheels, the rear omnidirectional wheels of the cleaning robot 200 can move to a predetermined position via the guide surface 21, the walking bridge 32, and the support 4. This design allows the cleaning robot 200 to better position its mopping components within the cleaning tank 3 after entering the cleaning base station 100. The rear omnidirectional wheels are mounted on the bracket 4, reducing the likelihood of the rear omnidirectional wheels interfering with other components during cleaning in the cleaning tank 3. Furthermore, the bracket 4 is detachably mounted on the cleaning tank 3, improving the ease of installation and removal. When the cleaning base station 100 is compatible with a cleaning robot 200 with rear omnidirectional wheels or both front and rear omnidirectional wheels, the bracket 4 can be mounted on the cleaning tank 3. When the cleaning base station 100 is compatible with a cleaning robot 200 with only front omnidirectional wheels, the bracket 4 can be detached from the cleaning tank 3, allowing the cleaning base station 100 to accommodate various types of cleaning robots 200. Therefore, the cleaning base station 100 of this application can simultaneously accommodate cleaning robots 200 with rear omnidirectional wheels or both front and rear omnidirectional wheels. Here, the first direction X is the direction in which the cleaning robot 200 enters the cleaning base station 100.

[0030] In some embodiments, the guide plate 2 is disposed on the base 1 in the first direction X, the cleaning tank 3 includes a tank body 31 adapted to the base 1, the tank body 31 is disposed on the base 1 in the second direction Y, the second direction Y is perpendicular to the first direction X, and the walking bridge 32 is connected to the wall of the tank body 31.

[0031] In some embodiments, one end of the walking bridge 32 is connected to the wall of the trough 31 near the guide surface 21, and the other end of the walking bridge 32 away from the guide surface 21 is connected to the bracket 4. The walking bridge 32 has a bridge surface 323 away from the base 1, and the bracket 4 has a frame surface 411 away from the base 1. The guide surface 21, the bridge surface 323, and the frame surface 411 are sequentially connected to form a walking surface. The height of the walking surface relative to the bottom surface of the base 1 gradually increases in the first direction X. When the cleaning robot 200 enters and exits the cleaning base station 100, it travels on the walking surface, which allows for a smooth transition and reduces the possibility of the cleaning robot 200 bumping or getting stuck due to sudden height changes, thus helping the cleaning robot 200 to enter and exit the cleaning base station 100 more smoothly.

[0032] In some embodiments, the height of the guide plate 2 gradually increases in the first direction X, causing the guide surface 21 to be inclined upward in the second direction Y, allowing the driving wheels 201 and auxiliary wheels 202 of the cleaning robot 200 to travel smoothly on the guide surface 21. The other end of the walking bridge 32 extends inclined upward in the second direction Y, causing the bridge surface 323 to be inclined upward in the second direction Y, allowing the auxiliary wheels 202 of the cleaning robot 200 to travel smoothly on the bridge surface 323. The extension direction of the bracket 4 near the walking bridge 32 is inclined upward in the second direction Y, causing the frame surface 411 to be inclined upward in the second direction Y, allowing the auxiliary wheels 202 of the cleaning robot 200 to travel smoothly on the frame surface 411.

[0033] In some embodiments, a stopping position 22 is provided in the transition area between the guide surface 21 and the base 1 in the first direction X. The stopping position 22 is recessed into the guide surface 21 and is used for the driving wheel 201 of the cleaning robot 200 to stop. There is a first distance between the stopping position 22 and the bracket 4, and a second distance between the driving wheel 201 and the auxiliary wheel 202 of the cleaning robot 200. The first distance and the second distance are adapted to each other, so that the stopping position 22 can allow the cleaning robot 200 to stop in place, and the bracket 4 does not need to be provided with an additional stopping abutment to prevent the auxiliary wheel 202 from disengaging from the bracket 4. The driving wheel 201 can be a drive wheel.

[0034] In some embodiments, in the first direction X, the guide surface 21 is provided with a protrusion 211 near the edge of the parking position 22. The protrusion 211 can prevent the driving wheel 201 located in the parking position 22 from sliding down, so as to assist the driving wheel 201 to stop in the parking position 22.

[0035] In some embodiments, please refer to Figure 1 , Figure 4 and Figure 5The walking bridge 32 has a first positioning groove 321 at one end away from the guide surface 21, and a second positioning groove 311 on the wall of the groove 31. One end of the bracket 4 has a first positioning post 43, and the other end has a second positioning post 44. The first positioning post 43 is inserted into the first positioning groove 321, and the second positioning post 44 is inserted into the second positioning groove 311. This allows the bracket 4 to be detachably mounted on the cleaning tank 3, thus improving the ease of installation and disassembly. Furthermore, when the cleaning base station 100 is adapted to a cleaning robot 200 with rear-mounted universal wheels or front and rear dual universal wheels, the bracket 4 can be mounted on the cleaning tank 3. When the cleaning base station 100 is adapted to a cleaning robot 200 with only front-mounted universal wheels, the bracket 4 can be detached from the cleaning tank 3, enabling the cleaning base station 100 to adapt to various types of cleaning robots 200.

[0036] In one embodiment, the second positioning groove 311 may be located on the bottom surface of the groove 31 near the base 1 to improve the stability of the connection between the bracket 4 and the groove 31.
