Automobile anti-collision beam

Abstract

The invention relates to an automobile anti-collision beam. An energy storage buffer box is of a structure that a piston is matched with an elastic piece; the elastic piece can effectively store impact energy, so that damage to passengers in an automobile is reduced, and the safety of pedestrians outside the automobile is protected. Under a low-speed condition, the elastic piece serves as an energy storage element to store certain collision energy, so that the safety of the passengers can be effectively protected. Compared with a traditional automobile anti-collision beam of which the energy absorption box is directly stressed to deform in a collision process, and the automobile anti-collision beam enables an energy absorption process to be smoother. Meanwhile, when automobiles collide with each other at a high speed, the hollow structure of the piston enables the elastic piece to be impacted by loads, subsequent metal plastic deformation can be generated to absorb impact energy aftera compression amount reaches a maximum value, and therefore, the safety of a passenger compartment is improved. Layered self-similar energy absorption boxes increase the energy absorption effect of the anti-collision beam.

Description

technical field [0001] The invention relates to an automobile anti-collision beam. Background technique [0002] With the increasing number of cars, the number of traffic accidents is also increasing when the development speed of social facilities lags behind the development speed of cars and people's driving behavior is not standardized. as obvious. At intersections or assembly areas with a large flow of people in the city, traffic accidents between pedestrians and cars are prone to occur due to too many pedestrians. Traditional cars often focus on traffic accidents between cars and ignore the collision between pedestrians and cars. Condition. The main part of the existing automobile anti-collision beam is a rigid structure, and this structure has almost no protection ability for pedestrians, so even if a traffic accident occurs with a pedestrian at a very low speed, it is likely to cause injury. At the same time, the anti-collision beam is an important device used to re...

Problems solved by technology

However, the existing anti-collision beams ignore the protection of pedestrians and have poor energy absorption efficiency. In the case of higher speed, it can not play a good role in protecting the occupants
