Abstract

The invention provides a structure proposal of an electric vehicle collision protection high-efficiency energy-absorbing island. The scheme sets up a beam system at the front of the car that can withstand the huge impact of a collision, and combines it with energy-absorbing foam materials to form an efficient energy-absorbing island structure for collision protection. When a car encounters an accidental collision, the beam body system supports the energy-absorbing island to absorb the huge impact kinetic energy of the colliding vehicle. At the cost of the collapse of the foam structure of the energy-absorbing island, it greatly absorbs and consumes the kinetic energy of the opponent's vehicle, protecting the safety of passengers on the own vehicle. At the same time, the beam system can further disperse the greatly reduced recoil of the energy-absorbing island to the battery case, avoiding fire and explosion caused by excessive force and deformation of the battery case, and minimizing collision hazards.

Description

technical field [0001] The invention relates to the technical field of electric vehicle collision protection, in particular to a high-efficiency energy-absorbing island structure for electric vehicle collision protection. Background technique [0002] Pure electric vehicles are the main form of new energy vehicles. Compared with traditional fuel vehicles, they have the following advantages: (1) Low pollution: almost "zero emission". (2) Low noise: The noise generated by pure electric vehicles can be ignored. (3) Low cost: The manufacturing cost of pure electric vehicles is low, and the operating cost is lower. (4) High efficiency: Pure electric vehicles have no waste heat. (5) Easy maintenance: only need to regularly check the motor battery and other components, easy maintenance. In addition, electric vehicles will soon become the best platform for low-carbon, informatization and intelligence. Therefore, all countries in the world have vigorously supported the developmen...
