A car anti-collision beam with good energy absorption effect

Abstract

The invention discloses an automobile anti-collision beam with good energy absorption effect, which comprises a front beam structure, a primary energy-absorbing structure, a cross column, a secondary energy-absorbing structure, a tertiary energy-absorbing structure and a beam group. The lower surface of the beam structure is fixedly installed with a primary energy-absorbing structure that can buffer impact forces in different directions. There is a horizontal column under the primary energy-absorbing structure, and the horizontal column is equipped with a structure that can buffer the energy from the primary energy-absorbing structure to a certain extent. A secondary energy-absorbing structure for structural impact, and the secondary energy-absorbing structure is elastically connected to the primary energy-absorbing structure, and the lower surface of the horizontal column is fixedly installed with a tertiary energy-absorbing structure that can buffer the impact force from the secondary energy-absorbing structure, The lower surface of the three-stage energy-absorbing structure is fixed with a crossbeam group, and through the mutual cooperation among the pre-beam structure, the first-stage energy-absorbing structure, the second-stage energy-absorbing structure, and the third-stage energy-absorbing structure, a high-efficiency hierarchical buffering effect is realized , play a very good role in energy absorption, to ensure that the entire beam group will not be deformed and damaged by too much impact.

Description

technical field [0001] The invention relates to the technical field of automobile anti-collision beams, in particular to an automobile anti-collision beam with good energy absorption effect. Background technique [0002] Automobile anti-collision beams are an important part of the body structure. They are generally installed on the front and rear bumpers, side doors, etc. of vehicles, which can directly protect the safety of drivers and passengers in collisions. Made of high-safety steel plates, when the collision force is applied, it will be transmitted to the frame of the vehicle to bear it. [0003] Generally, the first anti-collision beam of a car is an anti-collision steel beam, which is connected to the whole frame of the car through an energy-absorbing box. If it is passed to the beam, it cannot be buffered in stages, and the damage to the entire frame of the car body is relatively large, and the repair work in the later stage is difficult. [0004] Therefore, we pr...
