Split type automobile anti-collision beam convenient to maintain

Abstract

The invention discloses a split type automobile anti-collision beam convenient to maintain. The split type automobile anti-collision beam convenient to maintain comprises a cross beam, energy absorption boxes and an energy absorption protecting cover, wherein the energy absorption boxes are arranged on the back face of the cross beam in a spaced mode, and the energy absorption protecting cover isarranged on the front face of the cross beam and extends to the outer sides of the two ends of the cross beam; the energy absorption protecting cover comprises two U-shaped bending plates and connecting strips, wherein the connecting strips are arranged between the two parallel U-shaped bending plates in a spaced mode, and the positions of the connecting strips correspond to the energy absorptionboxes in a one-to-one mode; and bolts penetrating through the cross beam and connected with the energy absorption boxes are arranged on the connecting strips, and threaded sleeves corresponding to thebolts are arranged in the energy absorption boxes. Through the mode, according to the split type automobile anti-collision beam convenient to maintain, a split type structure is adopted, the maintenance convenience is high, the energy absorption protecting cover is specially designed to protect the front face of the cross beam, the energy absorption protecting cover can perform fold deformation so as to realize energy absorption when the energy absorption protecting cover bears force, the energy absorption protecting cover is matched with the energy absorption boxes to reduce the damage to anautomobile body, and the replacement proportion of the cross beam in accidents is reduced.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a split type automobile anti-collision beam which is convenient for maintenance. Background technique [0002] The anti-collision beam will plastically deform when the vehicle collides violently, absorb part of the impact and reduce further damage to the vehicle. Therefore, in order to improve the safety performance of the vehicle, most vehicles are equipped with anti-collision beams, but they are different from plastic bumpers. , the plastic deformation of the anti-collision beam has lost its original rigidity and needs to be replaced as a whole, which is relatively expensive. [0003] In order to reduce the maintenance cost of the anti-collision beam, some vehicles also install an energy-absorbing box between the beam and the longitudinal beam of the frame to achieve low-speed safety protection. As a metal thin-walled component, the energy-absorbing box is prone to wrinkle deformatio...

AI Technical Summary

Problems solved by technology

[0004] The energy-absorbing box is usually bolted or welded on the back of the beam, and it is difficult to disassemble after wrinkling and deformation

In addition, there is no energy-absorbing structure that can wrinkle and deform on the front of the beam, so that the front of the beam is prone to pits or bends during collisions. The proportion of repairs and replacements in accidents is still relatively high and needs to be improved.
