Crash protection efficient energy absorption island structure for electric automobile

Abstract

The invention provides a crash protection efficient energy absorption island structure for an electric automobile. According to the scheme, a beam body system capable of bearing great collisions is arranged on the portion of an automobile head and combined with an energy absorption foam material, and the crash protection efficient energy absorption island structure is formed. When the automobile crashes accidently, the beam body system supports an energy absorption island to bear great impact kinetic energy of a crashing vehicle, at the cost of the collapse of the foam structure of the energyabsorption island, the kinetic energy of the opposite vehicle is greatly absorbed and consumed, passengers on the automobile are protected to be safe, meanwhile, the beam body system can further scatter and evenly share the greatly-reduced recoil of the energy absorption island on a battery shell, the situation that a battery box receives too large force and then deforms, and thus the battery boxcatches fire and explodes is avoided, and crash damage is avoided to the maximum extent.

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...

AI Technical Summary

Problems solved by technology

Due to the strong activity of lithium itself, lithium-ion batteries have been plagued by battery safety issues for the development of the electric vehicle industry. Both lithium iron phosphate and ternary lithium batteries are prone to fire and explosion problems. Although through modern intelligent control technology, static The thermal runaway of the battery has been effectively contained in the environment, but it has not fundamentally solved the battery safety problem

The previous structural design of the co-installation of the energy-absorbing box and the main beam of the car body can no longer adapt to the new structural changes of electric vehicles
