DETAILED DESCRIPTION

[0020] See attached Figure 1 and 2 The present invention provides a battery locking and unlocking assembly for new energy passenger vehicles, comprising a lock plate 1 for locking and unlocking a locking mechanism that locks a battery pack, and a matching locking and unlocking drive assembly. The locking and unlocking drive assembly includes a mounting base 2, a transmission member 3 positioned within a drive slot 1-1 in the lock plate 1, and a drive component that drives the transmission member 3 horizontally and rotates the lock plate 1 through a predetermined angle to cooperate with the locking mechanism to unlock the battery pack or lock it.

[0021] The locking plate 1 is hinged to the mounting base 2. The locking plate 1 is hinged to the mounting base 2 via a hinge shaft 5. A spacer 6 is mounted on the hinge shaft 5. The installation of the spacer 6 allows the connecting plate 7 to be located inside the locking plate 1, which improves the compactness of the entire device.

[0022] The lock plate 1 is strip-shaped, and the top and front and rear sides of the unlocking portion 1-2 of the lock plate 1 are provided with inclined surfaces to facilitate contact with the unlocking portion 13-1 of the connecting rod 13 in the locking mechanism and drive the connecting rod 13 to move.

[0023] See attached Figure 1 The aforementioned driving components include two bearing blocks 8 fixed to the mounting base 2, a screw 9 with its ends respectively restrained by the two bearing blocks 8, a nut 10 threadedly connected to the screw 9, and a drive motor 11 that drives the screw 9 in rotation. The transmission member 3 is fixed to the nut 10. A connecting plate 7 is fixed to the nut 10, and the transmission member 3 is connected to the nut 10 via the connecting plate 7. In this embodiment, the transmission member 3 is a drive shaft connected to the connecting plate 7. To facilitate the movement of the transmission member 3 within the drive groove 1-1 when the lock plate 1 is driven to rotate, a roller 4 is provided on the transmission member 3.
