Since the driving assembly 30 cannot overcome the constraining force of the constraining assembly 60 to drive the cover 20 to open under the constraining action of the constraining assembly 60, before the cover 20 is opened, the constraining assembly 60 must be released from constraining the cover 20, and then the driving assembly 30 is controlled to drive the pin 40 to rotate to open the cover 20.

After receiving the opening signal, the actuating element 70 can break the connection state between the first member 61 and the second member 62, so that the first member 61 and the second member 62 are separated from each other, and the constraint action generated between the cover 20 and the body 10 due to the connection between the first member 61 and the second member 62 disappears.

In a specific embodiment, the first member 61 is movable relative to the body 10, for example, the first member 61 can rotate or translate relative to the body 10, and the actuator assembly 70 can drive the first member 61 to move relative to the body 10, so that the first member 61 is separated from the second member 62.

In the present application, the first member 61 is exemplified to be rotatable relative to the body 10, and as shown in fig. 4 and 5, the specific technical solution is as follows:

the first driving device 73 is also used for driving the reel 72 to rotate reversely, so that the pulling rope 71 is released from the reel 72.

As shown in the schematic diagram of fig. 4, the first member 61 includes a first end and a second end, the first end is used for connecting with the second member 62; with reference to the illustrated position, the pulling rope 71 is located on the left side of the first member 61, one end of the pulling rope 71 is connected to the second end of the first member 61, the other end of the pulling rope 71 is wound on the winding shaft 72 and is under tension, and when the winding shaft 72 rotates forward under the driving of the first driving device 73, the pulling rope 71 is gradually wound on the winding shaft 72, so as to drive the first member 61 to rotate from the first position to the second position in the clockwise direction, so that the first end of the first member 61 is far away from the second member 62.

When the spool 72 is driven by the first driving device 73 to reverse after the first member 61 is separated from the second member 62, the pull cord 71 will be released from the spool 72, so that the first member 61 can be returned to the first position by the reset assembly 80.

Alternatively, the pulling rope 71 may be located at the right side of the first member 61 and connected to the first end of the first member 61, and similarly, under the action of the first driving device 73, the pulling rope 71 will drive the first member 61 to rotate clockwise while being wound on the winding shaft 72, so as to separate the first member 61 from the second member 62, which will not be described in detail herein.

The first driving device 73 and the reel 72 may be fixed to the main body 10 or may be fixed to a device to which the charging device is attached.

As shown in fig. 5, the push rod 74 is located at the right side of the second end of the first member 61, under the action of the second driving device 75, the push rod 74 gradually approaches the second end of the first member 61, and after the push rod 74 contacts the second end of the first member 61, the push rod 74 is continuously driven to move, so that the first member 61 is driven by the push rod 74 to rotate in the clockwise direction, and the first member 61 is separated from the second member 62.

When the second driving device 75 drives the push rod 74 to move reversely, the push rod 74 can return to the initial position, and the first member 61 can also be reset under the action of the reset assembly 80.
