Collapsible front bumper mounting device

Abstract

The invention discloses a collapsible front bumper mounting device. The collapsible front bumper mounting device mainly comprises a collapsible front bumper mounting bracket, an upper collapsible bracket mounting plate, a lower collapsible bracket mounting plate and collapsible bracket buckles, wherein the collapsible front bumper mounting bracket, the collapsible bracket upper mounting plate and the collapsible bracket lower mounting plate form a section of common interference mounting part, and the frictional resistance of the part and the resistance provided by the collapsible bracket buckle jointly form the collapsible resistance of the device. According to the device, a vulnerable road user can be effectively protected, the trolleys are prevented from drilling and colliding, the collision compatibility between the vehicles is improved, the occurrence of malignant rear-end collision accidents is avoided, the design cost is low, the weight is light, the structural strength is high, the stability is good, and the production and the installation are convenient.

Description

technical field [0001] The invention relates to the technical field of structural design of automobile parts, in particular to a collapsible front bumper installation device. Background technique [0002] With the rapid progress of my country's industrial development and the significant improvement of people's living standards, cars have become an indispensable tool in people's daily life. However, the increasing number of cars will not only cause traffic congestion, but more importantly, the probability of collisions between cars and vulnerable road users (pedestrians and two-wheeler users) will greatly increase. In such accidents, vulnerable road users often lack adequate protection and are therefore extremely vulnerable. Therefore, while the number of automobiles is increasing rapidly, the improvement of automobile safety performance, especially the protection of vulnerable road users is imminent. [0003] During a frontal collision between a vulnerable road user and a ...

AI Technical Summary

Problems solved by technology

[0003] During a frontal collision between a vulnerable road user and a passenger car, the front bumper is in direct contact with the calf, knee joint, thigh, and pelvis of the vulnerable road user. If the front bumper cannot effectively collapse and absorb energy to form a buffer , not only will cause greater damage to the lower limbs of vulnerable road users, but the upper body and head of vulnerable road users are likely to hit the engine compartment cover or front windshield, causing greater damage

[0004] In the existing application of front bumper mounting brackets for passenger cars, a combination of sheet metal brackets and non-stretchable plastic brackets is generally used. However, the deformation of the sheet metal brackets and non-stretchable plastic brackets is limited, and the front bumper cannot form an effective collapse. Buffers, insufficient protection for vulnerable road users
