Since the charge-discharge expansion mechanism 100 provides the battery pack 230 with a mounting position independent of the electric device 220 and the receptacle 120 and the charge-discharge assembly 130 are configured to establish electric connection with the battery pack 230 and the electric device 220, respectively, so that electric connection between the battery pack 230 and the receptacle 120 and between the electric device 220 and the charge-discharge assembly 130 can be established individually at the time of wiring, instead of directly connecting the wiring to the battery pack 230 and the electric device 220, respectively, thereby simplifying the wiring scheme between the battery pack 230 and the electric device 220. In this way, when the self-mobile device 200 is maintained, the connection between the battery pack 230 and the socket 120, and between the power utilization device 220 and the charging and discharging assembly 130 can be disconnected, and then the battery pack 230 is removed from the docking station 110, so that the disassembly and assembly of the battery pack 230 are simplified, the time consumption of disassembly and assembly of the battery pack 230 is shortened, and the time consumption of disassembly and assembly of the self-mobile device 200 is shortened.

As shown in fig. 1 and 2, as an embodiment, the main body 210 includes a machine body 211 and a wheel assembly 212, a cavity 213 is provided in the machine body 211, the power device 220 and the charge-discharge expansion mechanism 100 are both accommodated in the cavity 213, and the wheel assembly 212 is rotatably connected to the bottom of the machine body 211 to drive the machine body 211 to travel on a supporting surface, which may be the ground.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the specification and drawings of the present utility model or direct/indirect application in other related technical fields are included in the scope of the present utility model.
