A vehicle anti-collision component

Abstract

The invention discloses a vehicle anti-collision assembly, which is used for a mounting seat installed on a longitudinal beam, a protection beam located in front of the mounting seat, an anti-collision beam located in front of the mounting seat, an energy absorbing box, and a bracket; the protection beam is located below the anti-collision beam; the energy-absorbing box is clamped between the anti-collision beam and the installation seat, and the bracket is clamped between the protection beam and the installation between the seats; the cross-sectional area of ​​the energy absorbing box gradually increases from back to front. The invention can fully absorb the energy generated by the collision, improve the safety performance of the vehicle, and effectively reduce the damage to personnel caused by the collision, and belongs to the technical field of automobile anti-collision structures.

Description

technical field [0001] The present invention relates to the technical field of automobile anti-collision structures, in particular to a vehicle anti-collision assembly. Background technique [0002] The energy-absorbing box and the anti-collision beam are very important metal components in the car. They play the role of deforming and absorbing energy, resisting the impact and protecting the safety of the members during the collision of the car. The anti-collision performance of the energy-absorbing box and the anti-collision beam is generally tested by a crash test. At present, MPDB (two vehicles colliding with each other at 50% of the vehicle width at a relative speed of 100kmph) has been added to the crash test of CNCAP vehicle collision avoidance device to more comprehensively examine the compatibility of the two-vehicle collision. In a collision accident, it can not only protect the occupants of the vehicle (crashworthiness), but also reduce the damage (aggressiveness) ...

AI Technical Summary

Problems solved by technology

The current energy-absorbing box and calf protection beam generally have a small front section and a large rear section, which is likely to cause breakdown of the aluminum foam of the trolley, and there is a high risk of penalty points in the crash test. Therefore, the existing energy-absorbing box and anti-corrosion The anti-collision performance of the collision beam is low, the safety of the car is not high enough, and it is easy to cause personal injury
