Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile accessories, and specifically relates to a lightweight passenger car rear anti-collision beam. BACKGROUND

[0002] The automobile anti-collision beam is a device for reducing the collision energy absorbed when a vehicle is subjected to a collision, which is composed of a main beam, an energy-absorbing box and a mounting plate connected to the automobile. The main beam and the energy-absorbing box can effectively absorb the collision energy when a low-speed collision occurs to the vehicle, thereby minimizing the damage of the impact force to the vehicle body longitudinal beam. In this way, the anti-collision beam plays a protective role for the vehicle. However, the main beam is usually a rigid structure, which cannot quickly and effectively eliminate the impact force when subjected to an impact. SUMMARY
