Small car front bumper with significant energy-absorbing effect

Abstract

The invention relates to a small car front bumper with significant energy-absorbing effect, which is used for solving the problems of insufficient energy absorption of energy-absorption boxes and the jointing of a crossbeam and skin. The bumper comprises the crossbeam and the energy-absorption boxes symmetrically arranged on both sides of the crossbeam; the upper wall and the lower wall of the crossbeam are wavy wall panels; the peaks and the troughs on the wavy wall panels extend to both ends of the crossbeam along the direction of the crossbeam, and the peaks and the troughs of the upper wall and the lower wall are symmetrically arranged. The Small car front bumper with significant energy-absorbing effect improves the energy-absorbing performance of the crossbeam by improving the structural design of the crossbeam and realizes the dual energy-absorbing effect of the energy-absorption boxes and the crossbeam so as to effectively improve the energy-absorbing level of the whole front bumper under the condition of not increasing the structural space of the energy-absorption boxes, and solve the problem of the balance of the security performance and the compact shape of the small car front bumper.

Description

technical field [0001] The invention relates to a vehicle component, in particular to a front anti-collision beam suitable for various small cars, and belongs to the technical field of automobiles. Background technique [0002] Cars are becoming more and more popular as a means of transportation and transportation, but traffic accidents are also gradually increasing. How to protect the safety of occupants and reduce the damage of important parts of cars in the event of car collisions has become an issue for various The direction of the car manufacturers' efforts. The front anti-collision beam is one of the main safety components of the car, and the energy absorption effect of the front anti-collision beam structure in the frontal collision is an important measure of the safety performance of the car. At present, the beam in the front anti-collision beam is used as a component for transmitting force, and basically does not absorb energy or only has a very small energy absorp...

AI Technical Summary

Problems solved by technology

When the energy absorption of the front anti-collision beam structure is insufficient, the energy-absorbing effect is mainly increased by changing the arrangement of the energy-absorbing ribs on the energy-absorbing box. Very insufficient, no matter how to change the arrangement of energy-absorbing ribs on the energy-absorbing box, the energy absorption of the front anti-collision beam can only be within a limited range, and cannot be greatly improved

For this problem, automobile manufacturers can only choose between slightly inferior safety performance and changing the shape of the car. Usually, small car manufacturers have no choice but to accept the reality of low safety performance
