Background

Along with the development of the automobile market in China and frequent traffic accidents, people pay more and more attention to the safety of automobiles. Before, a relatively strict and fair collision standard does not exist in China, and with the fact that collision tests of middle and old research are published, a plurality of vehicle types cannot meet the standard. In particular, the shock developed in the future is referenced to the American IIHS standard, incorporating a frontal 25% offset shock at 64km/h, which was an unprecedented challenge for vehicle enterprises.

And 25% of the front collision avoidance and longitudinal beam area is ingeniously avoided at the collision position. And many vehicle enterprises only pay attention to the front anti-collision beam, and due to the limitation of mechanism space, the requirements on the structural strength of the side wall and the vehicle door are very high. The side panel must effectively disperse the impact force and the door must support the side panel well. Therefore, the impact beam of the door is to withstand both side and frontal impacts.

The front end and the rear end of the existing automobile anti-collision beam are mostly in a Y-direction lap welding structure with the inner plate, the structure only considers the side collision effect, and the front and rear supporting effect on the front and rear collision is small. When 25% of offset collision happens on the front surface, the collision force is mainly transmitted to the side wall, the force of the side wall is transmitted to the vehicle door, and the vehicle door is easy to deform because the anti-collision beam cannot play a good supporting role on the front part, so that the A column is easy to deform.
