When the sweeping robot 1 needs to disassemble the mop assembly 12, the sweeping robot 1 moves to the base 21, and the driving device 221 drives the driving member 223 to move through the transmission assembly, and the driving member 223 drives the slider 222 to press the button 132, so that the button 132 is disengaged from the buckle 131, thereby unlocking the locking mechanism 13, and the mop assembly 12 can be disassembled when the robot body 11 of the sweeping robot 1 is withdrawn from the base 21.

[0098] As an embodiment of the present invention, the driving member 223 is disposed on the cleaning brush 25 and moves synchronously with the cleaning brush 25; the transmission assembly can drive the cleaning brush 25 to move between the first position and the second position to clean the mop assembly 12, and the transmission assembly can drive the cleaning brush 25 to move to the third position so that the driving member 223 drives the slider 222 to unlock the locking mechanism 13.

[0099] As an embodiment of the present invention, the base 2 is provided with detection sensors 27 for detecting the position of the cleaning brush 25 corresponding to the first position, the second position and the third position, respectively, and each detection sensor 27 is electrically connected to the first control unit. Fig.11 The three detection sensors 27 correspond to the first position, the second position and the third position from right to left.

[0100] In this embodiment, by respectively arranging detection sensors 27 at the corresponding first position, second position and third position on the base 2, it is convenient to detect the movement position of the cleaning brush 25, and it is convenient for the first control unit to control the movement of the cleaning brush 25 according to actual needs.

[0101] As an embodiment of the present invention, the detection sensor 27 is a Hall sensor, and a magnet 28 is fixed at one end of the cleaning brush 25. The Hall sensor detects a magnetic field signal to determine the movement position of the cleaning brush 25. The structure is simple and the implementation cost is low. For example, when the detection sensor 27 at the second position detects a magnetic field signal, it can be determined that the cleaning brush 25 has moved to the second position.

[0102] Among them, three detection sensors 27 are arranged in sequence and spaced apart, and the three detection sensors 27 divide two movement areas. When the driving device 221 drives the cleaning brush 25 to reciprocate in the movement area between the first position and the second position, the cleaning brush 25 can clean the mop assembly 12; when the cleaning brush 25 enters the movement area between the second position and the third position, the driving member 223 on the cleaning brush 25 will push the slider 222 to move, so that the slider 222 is pushed out in the direction of the button 132, thereby unlocking the lock mechanism 13; when the cleaning brush 25 exits the movement area between the second position and the third position, the driving member 223 on the cleaning brush 25 will leave the slider 222, and the slider 222 is reset by the elastic member 224, so that the button 132 can be automatically reset, so that the lock mechanism 13 is re-locked. In addition to this embodiment, the detection sensor 27 can also be an infrared sensor, and the cleaning brush 25 does not need to be provided with a magnet 28, and the infrared sensor can be used to directly detect the movement position of the cleaning brush 25.

[0103] As an embodiment of the present invention, the bottom of the slider 222 is provided with a first inclined surface, and the driving member 223 is provided with a second inclined surface that matches the bottom of the slider 222. When the cleaning brush 25 enters the second movement area, the second inclined surface of the cleaning brush 25 pushes the first inclined surface at the bottom of the slider 222, so that the slider 222 pushes the button 132 toward the middle. The slider 222 and the driving member 223 cooperate with each other through the inclined surfaces, so that the slider 222 moves more smoothly.

[0105] Two sets of pulleys 261 drivingly connected to the driving device 221; and

[0106] The two belts 262 are respectively connected to the two sets of pulleys 261 , and the two ends of the cleaning brush 25 are respectively fixed on one belt 262 .

[0107] In this embodiment, a set of pulleys 261 are respectively provided on both sides of the base 21, and each set of pulleys 261 is driven by a belt 262. The two ends of the cleaning brush 25 are respectively fixed on a belt 262, and the two belts 262 simultaneously drive the cleaning brush 25 to move forward and backward. In addition, the pulleys 261 and the belts 262 can also be replaced by sprockets and chains.

[0108] As an embodiment of the present invention, the transmission assembly 26 further includes:

[0109] The gear reduction box 264 has an input shaft connected to the driving device 221 , and an output shaft connected to a cross bar 265 , and both ends of the cross bar 265 are respectively connected to one of the two groups of pulleys 261 .

[0110] In this embodiment, the first control unit controls the operation of the driving device 221, and the driving device 221 drives the cross bar 265 to rotate forward or reversely. The cross bar 265 also drives the two sets of pulleys 261 to rotate synchronously, so that the two belts 262 can move forward and backward synchronously. The two belts 262 drive the cleaning brush 25 to move forward and backward to clean the mop assembly 12 or drive the driving member 223 to drive the slider 222 to unlock or lock the locking mechanism 13.
