In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

In order to prevent foreign matters such as impurities from entering the clean water tank of the cleaning robot to affect normal water outlet, a baffle is usually hinged at a water injection port of the clean water tank. And when the baffle is hinged behind the water injection port, the damping that the baffle received is great, and stability is higher, therefore, when cleaning robot rocks because of the ground is uneven, the baffle still can cover to establish in water injection port department, can not swing at will, avoids the foreign matter to get into.

Referring to fig. 1-4, one embodiment of the present application provides an automatic replenishment station 10 comprising: a base 110 and a clear water docking mechanism 120. The clean water docking mechanism 120 includes a water injection arm 121 and a first elastic member 122. The water injection arm 121 is movably connected with the base 110 and is configured to extend into a clean water tank 210 on the cleaning robot 20. The first elastic member 122 abuts between the water injection arm 121 and the base 110. The first elastic member 122 is used to apply elastic force to the water injection arm 121 in a direction away from the base 110 when the cleaning robot 20 moves in a direction approaching the base 110 to make the water injection arm 121 abut against the baffle 211 hinged on the cleaning tank 210.

In the automatic replenishment station 10, since the clean water docking mechanism 120 includes the water filling arm 121, when the cleaning robot 20 moves toward the substrate 110, the water filling arm 121 contacts the baffle 211 on the clean water tank 210, and then the baffle 211 is pushed continuously to rotate the baffle 211, so that the water filling arm 121 can extend into the clean water tank 210 for filling water. The water injection arm 121 is in butt joint with the baffle 211 and promotes baffle 211 pivoted in-process, and baffle 211 can exert reaction force to water injection arm 121, because clear water docking mechanism 120 still includes first elastic component 122, and water injection arm 121 is relative base member 110 swing joint, first elastic component 122 sets up between water injection arm 121 and base member 110, consequently, when water injection arm 121 and baffle 211 contact, under the effect of first elastic component 122, can make water injection arm 121 obtain the buffering, can effectively avoid rigid contact between water injection arm 121 and the baffle 211.

Specifically, in this embodiment, the cleaning robot 20 is provided with a radar and an identification component, which are matched with each other to realize automatic and accurate butt joint between the clean water tank 210 and the water injection arm 121 of the cleaning robot 20. Specifically, the surface of the substrate 110 provided with the water injection arm 121 is regarded as the front surface of the substrate 110, and during the docking process of the cleaning robot 20 and the automatic replenishment station 10, firstly, when the cleaning robot 20 is located at a distance of about 1 meter from the automatic replenishment station 10, the radar on the cleaning robot 20 automatically recognizes the recognition feature on the front surface of the automatic replenishment station 10, and the recognition component (for example, MARK camera) on the cleaning robot 20 is combined with the recognition component slowly approaching the automatic replenishment station 10 and corrects the orientation of the cleaning robot 20, so that the clean water tank gradually faces the front surface of the automatic replenishment station 10. After the cleaning robot 20 is orientated, it continues to slowly approach the auto replenishment station 10 to align the water arm 121 with the fresh water tank 210 so that the water arm 121 can extend into the fresh water tank 210 after docking.

Referring to fig. 1 and 4, in an embodiment, the clean water docking mechanism 120 further includes a supporting base 123 and an abutment block 124. The supporting base 123 is connected with the base 110, and the water injection arm 121 is slidably disposed on the supporting base 123. In this way, the water injection arm 121 may be disposed on the base 110 and may also be movable relative to the support base 123 and the base 110.

Specifically, the abutment block 124 is sleeved outside the water injection arm 121, and the first elastic member 122 abuts between the support base 123 and the abutment block 124. When the water injection arm 121 abuts against the baffle 211, the cleaning robot 20 continues to move towards the base 110, the baffle 211 rotates under the action of the water injection arm 121, and the water injection arm 121 and the abutment block 124 move towards a direction away from the cleaning robot 20 relative to the support base 123 under the reaction force provided by the baffle 211, so that the first elastic member 122 is compressed. When the baffle 211 rotates to a certain angle, the reaction force of the baffle 211 to the water injection arm 121 is smaller than the restoring force of the first elastic member 122, and the first elastic member 122 is restored to push the water injection arm 121 to extend into the clean water tank 210, so that the reliability of the water injection arm 121 extending into the clean water tank 210 can be improved.

The second elastic member 132 is used to apply an elastic force to the plug assembly 131 in a direction away from the base 110 when the charging socket of the cleaning robot 20 is in plug-in engagement with the plug assembly 131. Thus, the stability of the plug assembly 131 after being in butt joint with the charging socket can be improved, and the reliability of the charging process can be improved.

Further, in one embodiment, as shown in fig. 3 and 5, the charging docking mechanism 130 further includes a support guide 133.
