The lifting rods 54 move together with the lifting plate 53. The lifting plate 53 drives the battery tray to move, so as to realize the adjustment of the position height of the battery.

[0046] As Figure 1 and Figure 4As shown, in some embodiments, the lifting mechanism 5 further includes a guide rod 56 and a linear bearing 55.

By providing the guide rod 56 and the linear bearing 55, the linear bearing 55 passes through the third mounting bracket 51, and the guide rod 56 passes through the linear bearing 55 and is connected to the lifting plate 53. When the lifting cylinder 52 expands and contracts to drive the lifting plate 53 to move, the lifting plate 53 drives the guide rod 56 to move along the linear bearing 55, and the linear bearing 55 can play a guiding role.

[0047] As Figure 1 and Figure 5 As shown, in some embodiments, the device further includes a lifting limit mechanism 6.
