Abstract

The invention particularly discloses an anti-collision box for a battery pack of an electric automobile, and belongs to the technical field of automobile batteries. The anti-collision box comprises abattery box, wherein the battery box comprises an elliptical anti-collision box and an elliptical battery pack box, and the elliptical battery pack box is arranged in the elliptical anti-collision box; a wave-shaped anti-collision plate is arranged on the outer side surface of the elliptical anti-collision box; a protective interlayer is arranged on the bottom surface of the outer side of the elliptical anti-collision box; a plurality of damping spring sets which are sequentially arranged from bottom to top are arranged in a cavity formed between the elliptical anti-collision box and the elliptical battery pack box; the damping spring sets comprise a plurality of double 8-shaped damping springs which are connected end to end; the elliptical battery pack box is sequentially provided with three elliptical battery separators from outside to inside, and the elliptical centers of the elliptical battery separators are arranged on the elliptical center of the elliptical battery pack box. Theanti-collision box is novel in design, can well protect the battery pack, and prevents the battery pack from being damaged, burnt and exploded when being impacted.

Description

Technical field [0001] The invention belongs to the technical field of automobile batteries, and in particular relates to an electric automobile battery pack anti-collision box. Background technique [0002] With the improvement of people’s awareness of environmental protection and the improvement of environmental protection requirements, the promotion of new energy vehicles has reached a considerable scale. In the existing new energy vehicles, the car battery is the core component. Compared with the traditional car in the collision of electric vehicles The particularity reflects that high-energy, large-mass power batteries may cause fire and explosion when they are crushed in a collision. The current method of avoiding collisions for battery boxes is usually to increase the strength of the battery box itself, but the strength of the material The upper limit of its use, and the higher the strength, the more expensive the cost. In addition, the battery box is fixed on the chassis ...
