Description

Technical Field

[0002] The anti-collision beam of the car is located at the front end of the car. It consists of a crossbeam and energy absorption boxes on both sides. The front anti-collision beam of the car is connected to the longitudinal beam through the bottom plate. At present, with the continuous improvement of people's requirements for automobile safety, automobile collision tests are becoming more and more stringent. In the China Insurance Automobile Safety Index Test and Evaluation System, there is a frontal 25% offset collision condition with a collision speed of 64km / h. Compared with a relatively large area of ​​frontal collision, the local force of a small offset collision is greater, and the probability of injury to the occupants of the car is higher.

[0003] Since the coverage of the barrier and the vehicle body is very small, only 25%, during a collision, the barrier will directly bend the front anti-collision beam, and directly hit the small longitudinal beam and the front suspension system along the energy absorption box and the left side of the longitudinal beam. The energy absorption box cannot deform and absorb energy during a collision, causing the impact energy to be easily transferred to the passenger compartment, causing damage to the occupants.
