[0071] The cover body device 10 provided in the embodiment of the present application, the setting of the rotational connection between the first rotating member 411 and the connecting rod 412 is conducive to the switching of the state of the front cover 200, and avoids the movement of the second part 420 along the guide groove 520 being hindered due to the inability of the first rotating member 411 and the connecting rod 412 to rotate relative to each other, thereby hindering the switching of the state of the front cover 200.

[0072] In some embodiments, the connecting rod 412 is provided with a first connecting hole and a second connecting hole at both ends, the first part also includes a pin shaft 413, the pin shaft 413 is inserted in the first connecting hole and the first rotating member 411, and the driving member 300 includes an output shaft 310, and the output shaft 310 is inserted in the second connecting hole.

[0073] The cover device 10 provided in the embodiment of the present application realizes the rotational connection between the first rotating member 411 and the connecting rod 412 by inserting the pin shaft 413 into the first connecting hole and setting the first rotating member 411, allowing the first rotating member 411 to rotate relative to the connecting rod 412 while maintaining the relative positions of the two, thereby realizing the normal operation of the first part.

[0076] In some embodiments, a slot 4123 is provided on one side of the connecting rod 412 close to the connecting shaft 600, and the cover device 10 further includes a stopper 700 and an elastic member 800. The stopper 700 is located in the chamber 120, and the stopper 700 is located on one side of the connecting shaft 600 close to the charging port avoidance hole 110. The elastic member 800 is passed through the connecting shaft 600, one end of the elastic member 800 abuts against the stopper 700, and the other end of the elastic member 800 extends into the slot 4123 of the connecting rod 412.

[0077] The shape of the limiting block 700 includes but is not limited to a rectangular parallelepiped, a cube or other special shapes.

[0079] The cover device 10 provided in the embodiment of the present application, exemplarily, when the connecting rod 412 rotates clockwise, the front cover 200 is switched from the closed state to the open state, and when the connecting rod 412 rotates counterclockwise, the front cover 200 is switched from the open state to the closed state. Since one end of the elastic member 800 abuts against the limit block 700, and the other end of the elastic member 800 extends into the slot 4123 of the connecting rod 412, the elastic member 800 is deformed when the connecting rod 412 rotates clockwise and provides resistance to the state switching of the front cover 200, so that the movement of the front cover 200 is smoother. When the front cover 200 is switched from the open state to the closed state, when the connecting rod 412 rotates counterclockwise, the elastic member 800 will simultaneously restore to its original state and provide power for the state switching of the front cover 200, so that the front cover 200 is more labor-saving when closing.

[0080] In some embodiments, the second portion 420 includes a second rotating member 421 and a driven rod 422. The second rotating member 421 is fixedly connected to the front cover 200. The driven rod 422 is located between the second rotating member 421 and the guide assembly 500, and the driven rod 422 is rotatably connected to the second rotating member 421. In the closed state, one end of the driven rod 422 extends into the limiting groove 530, and in the open state, one end of the driven rod 422 extends into the guide groove 520.

[0083] The cover device 10 provided in the embodiment of the present application realizes a movable connection with the front cover 200 and movement along the guide assembly 500 through the arrangement of the second rotating member 421 and the driven rod 422. The movable connection between the second rotating member 421 and the driven rod 422 provides a condition for the state switching of the front cover 200. If the two are fixedly connected, the state switching of the front cover 200 cannot be realized, so that the overall layout and components of the cover device 10 are simple.
