Description

Technical Field

[0001] The utility model relates to an anti-collision cross beam for an automobile. Background Art

[0002] The anti-collision beam is a device used to reduce the impact energy absorbed when the vehicle is hit. It consists of a main beam, an energy absorption box, and a mounting plate connected to the car. The main beam and the energy absorption box can effectively absorb the collision energy when the vehicle collides at a low speed, and minimize the damage to the longitudinal beam of the vehicle body caused by the impact force. In this way, it plays a protective role for the vehicle. The anti-collision beam structure should be able to ensure that the low-speed energy absorption box can effectively absorb the energy of a low-speed collision through collapse.

[0003] During the use of the anti-collision beam, the anti-collision effect of the anti-collision beam is not ideal. It is difficult to effectively absorb the kinetic energy generated by the collision and protect the colliding vehicle. In addition, during the collision, the bracket used for spring guidance is prone to tilt and damage in a lateral collision, which reduces the buffering effect and greatly reduces the protective performance of the existing anti-collision vehicle.
