The storage mechanism 2 includes a base 21, a battery storage component 22, and a horizontal sliding component 23. The battery storage component 22 is horizontally slidably connected to the base 21 in a first horizontal direction through the horizontal sliding component 23. The battery storage component 22 is provided with a battery storage slot 221 having an open end 2211. The battery passes through the open end 2211 and enters and exits the battery storage slot 221 in a second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction. The lifting mechanism 3 is disposed on the frame 1 and connected to the base 21, and the lifting mechanism 3 is used to drive the storage mechanism 2 to vertically lift and lower.

It should be noted that the first driving wheel 3311 and the first driven wheel 3312 cooperate to drive the first belt 3313 to rotate, the second driving wheel 3321 and the second driven wheel 3322 cooperate to drive the second belt 3323 to rotate, and the first belt 3313 and the second belt 3323 rotate synchronously to achieve the stable lifting of the coupling assembly 31. Among them, the first driven wheel 3312 and the second driven wheel 3322 are respectively arranged directly below the first driving wheel 3311 and the second driving wheel.

[0042] As Figure 4 shown, in one embodiment, the coupling assembly 31 includes a vertical sliding assembly 311, a lifting part 312, a pressing plate part 313, a pressing plate connecting part 314, and a lifting coupling part 315.

Among them, the lifting part 312 is arranged on one side of the first belt 3313 and the second belt 3323, the pressing plate part 313 is arranged on the first belt 3313 and the second belt 3323, and the pressing plate connecting part 314 is arranged between the pressing plate part 313 and the lifting part 312. It should be noted that the pressing plate part 313 and the lifting part 312 are fixedly connected through the pressing plate connecting part 314 so that the transmission of the first belt 3313 and the second belt 3323 can drive the lifting coupling part 315 to lift.

[0043] As Figure 4 shown, in one embodiment, the vertical sliding assembly 311 includes a vertical slide rail mounting part 3111, a vertical slide rail 3112, and a vertical slider 3113.

By pressing the first buffer and limit block 42 with the limit connecting piece 41, the guide shaft 44 is moved downward until it reaches the second buffer and limit block 46 and cannot move downward any further, thus achieving the effect of limiting and reducing the sound generated by the collision between the limit connecting piece 41 and the guide shaft 44. The elastic member 47 is sleeved on the guide shaft 44 so that when the limit connecting piece 41 moves downward and contacts the first buffer and limit block 42, the elastic member 47 is compressed to generate an elastic force, which plays a buffering role for the limit connecting piece 41. The guide shaft 44 is arranged in the guide hole of the buffer and limit mounting seat 43, and the guide shaft sleeve 44 is arranged on the buffer and limit mounting seat 43 and sleeved on the guide shaft 44 to enable the guide shaft 44 to move vertically in the guide shaft sleeve 44.
