[0058] The mop assembly 3 can be placed flat in the maintenance cavity 221 when the first spring and the second spring in the energized state push the first locking buckle and the second locking buckle back to the position where the locking assembly is in the engaged state. When the locking assembly is in the engaged state, the locking assembly can be engaged with the hook assembly on the bottom shell, thereby fixing the bottom shell and the mop assembly 3.

[0059] In the robotic cleaner provided by the above embodiment, the first locking buckle and the second locking buckle can be arranged adjacent to the edge of the mop support 31, so that the disassembling assembly on the maintenance station 2 can conveniently disassemble the mop assembly 3 on the robot body 1.

[0060] In the robotic cleaner provided by the above embodiment, the disassembling assembly can include a first disassembling rod 51 and a second disassembling rod 51'. When the robot is in the maintenance cavity 221, the first end of the first disassembling rod 51 is opposite to the end of the first connecting part 42 away from the first hook arm 41, and the first end of the second disassembling rod 51' is opposite to the end of the second connecting part 42' away from the second hook arm 41'.

[0063] In a specific embodiment, the driving assembly can specifically include a first rack 61, a second rack 61', a first gear 62, a second gear 62', a first motor 63, and a second motor 63'. The first rack 61 is connected with the second end of the first dismounting rod 51 and has the same extension direction as the first dismounting rod 51. The first gear 62 is engaged with the first rack 61 and is arranged on the rotating shaft of the first motor 63. The second rack 61' is connected with the second end of the second dismounting rod 51' and has the same extension direction as the second dismounting rod 51'. The second gear 62' is engaged with the second rack 61' and is arranged on the rotating shaft of the second motor 63'.

[0064] In the above driving assembly, when the rotating shaft of the first motor 63 rotates in a first preset direction, the first motor 63 can drive the first gear 62 to rotate, the first gear 62 can drive the first rack 61 to move, so that the first dismounting rod 51 extends into the maintenance cavity 221, and the first dismounting rod 51 pushes the first lock catch to move towards the second lock catch. When the rotating shaft of the second motor 63' rotates in a second preset direction, the second motor 63' can drive the second gear 62' to rotate, the second gear 62' can drive the second rack 61' to move, so that the second dismounting rod 51' extends into the maintenance cavity 221, and the second dismounting rod 51' pushes the second lock catch to move towards the first lock catch, thereby making the first lock catch and the second lock catch in the unclamped state, and achieving automatic dismounting of the mop assembly 3 on the bottom shell. When the first motor 63 and the second motor 63' rotate in directions opposite to the first preset direction and the second preset direction, respectively, the movement of the first rack 61 and the second rack 61' can drive the first dismounting rod 51 and the second dismounting rod 51' to retract into the containing space 222.

[0065] In a specific embodiment, a control unit is further arranged in the containing space 222, and the control unit is used to control the rotation of the first motor 63 and the second motor 63'. The control unit can control the state of the first dismounting rod 51 and the second dismounting rod 51' in the dismounting assembly by controlling the rotation direction of the first motor 63 and the second motor 63'.

[0066] In a possible implementation, the bottom plate 21 can be provided with at least one alignment slot extending towards the opening of the maintenance cavity 221, and the side of the mop support 31 adjacent to the bottom plate 21 can be provided with an alignment part corresponding to the alignment slot, so that the robot body 1 and the maintenance cavity 221 can be aligned through the one-to-one matching of the alignment part and the alignment slot during the movement of the robot body 1 towards the inside of the maintenance cavity 221.

[0067] The mop assembly 3 is fixed to the bottom shell, and the robot can clean the ceramic tile floor or the floor. After the robot finishes cleaning the ceramic tile or the floor, the robot returns to the maintenance cavity 221 of the maintenance station 2 when receiving the next cleaning instruction. The robot feeds back the received instruction to the control unit of the maintenance station 2, and the control unit controls the first motor 63 and the second motor 63' to rotate, drives the first gear 62 and the second gear 62' to rotate, and then drives the first dismounting rod 51 on the first rack 61 and the second dismounting rod 51' on the second rack 61' to extend into the maintenance cavity 221, pushes the first lock catch and the second lock catch on the mop support 31 to move towards the opposite direction, so that the first lock catch and the second lock catch on the mop are disengaged from the first hook part and the second hook part 71' on the bottom plate 21. At this time, the robot body 1 leaves the maintenance station 2, and the mop assembly 3 stays in the maintenance cavity 221 of the maintenance station 2. The robot can clean the carpet without wetting the carpet with wet mops. After the robot body 1 leaves the maintenance station 2, the control unit controls the first driving motor and the second driving motor to rotate again, so that the first dismounting rod 51 and the second dismounting rod 51' are retracted into the protective shell 22, and the mop assembly 3 is placed flat in the maintenance cavity 221.

[0068] When the robot body 1 finishes cleaning the carpet and returns to the maintenance station 2 to charge, add water, or clean the dust box inside the robot body 1, the mop assembly 3 is at the bottom of the maintenance cavity 221. When the robot body 1 moves towards the inside of the maintenance cavity 221, the first slope of the first hook part on the bottom shell and the first slope of the second hook part 71' on the bottom shell respectively slide and press the second slope of the first hook arm 41 and the second slope of the second hook arm 41', the first lock catch and the second lock catch move towards the opposite direction, and the first hook part and the second hook part 71' continue to move to the position where they can be engaged with the first hook arm 41 and the second hook arm 41'. Due to the pushing force of the first spring and the second spring 43', the first lock catch and the second lock catch return to the position where the lock catch assembly is engaged, and the first hook part and the second hook part 71' are engaged with the first hook arm 41 and the second hook arm 41', respectively. At this time, the robot body 1 can stop moving, and the mop assembly 3 is fixed to the bottom shell of the robot body 1.

[0069] The sweeping robot provided by the embodiment of the present application can have higher automation performance, can clean various environments, and can automatically switch states without manual intervention when the scene to be cleaned is changed, thereby improving user experience.

[0070] Obviously, various modifications and variations of the present application can be made by those skilled in the art without departing from the spirit and scope of the application. Thus, it is intended that the present application cover modifications and variations of this application provided they come within the scope of the appended claims and their equivalents.
