Problems solved by technology

[0004] However, when the vehicle actually collides, most of them are oblique collisions (non-frontal collisions) and other complicated situations, which lead to uneven collision force on the car crash box and can not be uniformly deformed, which reduces the energy absorption effect of the car crash box

Abstract

The invention discloses an automobile crash box, relates to automobile accessories and provides an energy absorbing device which is uniform in deformation and good in crash energy absorbing effect. The automobile crash box in the embodiment comprises a tubular crash box body, one end of the crash box body is provided with a front mounting plate connected with an anticollision beam of an automobile, and the other end of the same is provided with a rear mounting plate connected with a longitudinal beam of the automobile. The side wall of the crash box body is provided with crumple grooves recessed inwardly, and at least one guide plate is fixed on at least one side wall of the crash box body and provided with a weakening structure corresponding to the crumple grooves. When automobiles crash, the weakening structures of the guide plates can deform and guide the crumple grooves to crumple and absorb energy. The automobile crash box is mainly applied to automobiles.

Description

technical field [0001] The invention relates to the technology of automobile accessories, in particular to an automobile energy-absorbing box. Background technique [0002] In today's society, with the improvement of the economy and living standards, people are increasingly using cars as a means of transportation for travel. At the same time, people are paying more and more attention to the safety of cars. [0003] At present, due to the increasing number of vehicles and the increasingly complex road conditions, accidents such as collisions are extremely prone to occur in the process of driving a car, and most of them are frontal or rearward collisions (rear collisions) at low speeds. In the prior art, in order to effectively improve the protective effect of the front anti-collision beam and the rear anti-collision beam under the low-speed collision of the car, the front anti-collision beam and the front longitudinal beam, the rear anti-collision beam and the rear longitudin...
