Principle of embodiment:
in normal conditions, the cylinder 21 and the first air passage 6 are both provided with compressed air, so that the plunger 3 and the cylinder 21 provide better support for the cabinet 1. When the front side of the vehicle collides, the cabinet bodies 1 move forwards along the sliding rail 20 under the action of inertia, the plungers 3 are damped and buffered under the action of compressed gas, and the distance between the adjacent cabinet bodies 1 is reduced, so that the batteries in the accommodating space are protected.
When the container 26 encounters a rear-end collision, the rear side of the container 26 is deformed by the collision, and at this time, the piston rod 24 moves forward, the air pressure in the cylinder 22 rises, and since the air intake hole 16 and the cylinder 22 are communicated, the air pressure on the lower side of the first piston 9 rises, and the first piston 9 drives the connecting rod 12 and the hook 13 to move upward.
