Abstract

The invention relates to an electric vehicle battery pack cushioning device, which effectively solves the problem that the current electric vehicle battery cushioning device has bad effect. The technical solution includes an inner box and an outer box, the battery pack is placed in an inner box, A guide post is arranged on the inner box, the outer box is provided with a first blind hole which canbe matched with a guide post, A first piston is mounted in the first blind bore, the first blind hole is externally provided with a second blind hole in the direction of the first blind hole, A secondpiston is mounted in the second blind bore, the second piston is connected with a piston rod, the first blind hole is provided with an arc-shaped pressing piece, the piston rod is connected with thearc-shaped pressing piece, an oil passage is communicated between the first blind hole and the second blind hole, a plurality of exhaust holes with small apertures are arranged on the inner wall of the first blind hole between the first piston and the orifice, and gas in the first blind hole can be slowly discharged through the exhaust holes; The cushioning process of the invention is stable, andthe cushioning process can effectively cushion large and small impact, and the upper limit of the cushioning force is high, and the cushioning process is safe and reliable.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a buffer device for battery packs of electric vehicles. Background technique [0002] Electric vehicles are the main direction of automobile research and development at present; as the power source of electric vehicles, the chemical reaction process of batteries will not produce harmful products, the pollution is extremely small, and the energy conversion efficiency of batteries is 2 to 3 times higher than that of internal combustion engines. Therefore, electric vehicles have good prospects for promotion. [0003] The current battery packs are mostly fixedly installed in the battery box. Frequent acceleration and deceleration during the driving process of the car will easily cause loosening or collision between the battery and the battery box. damage, thereby reducing the service life of the battery; especially when the vehicle is running at high speed, if the vehicle brakes sud...
