Automobile small-offset collision test barrier

Abstract

The invention relates to an automobile small-offset collision test barrier with simple structure. The automobile small-offset collision test barrier comprises a rigid barrier main body assembly (1), the rigid barrier main body assembly comprises a connecting piece (15), a frame body (14), a support body (13), a main collision plate (12), and an arc-shaped side collision plate (11) connected at the rear side of the main collision plate and bending towards the left, the automobile small-offset collision test barrier also comprises a base (2) and a floor (3), the base comprises a bottom installing plate (21) and a side installing plate (22) connected to the right end of the bottom installing plate (21) and vertically extending in an upward manner, the floor comprises a body (31), the connecting piece of the rigid barrier main body assembly is connected with the side installing plate (22) of the base, the bottom installing plate of the base is detachably connected with the body of the floor, the bottom installing plate of the base can move back and forth relative to the body of the floor, and the body of the floor is fixed on the ground.

Description

technical field [0001] The invention belongs to automobile collision test equipment, in particular to a small offset collision test barrier for automobiles. Background technique [0002] According to statistics, among all automobile accidents, the casualties caused by frontal collision accidents of automobiles account for the largest proportion, and among them, small overlap frontal collision accidents of automobiles are the main cause of death of people inside the vehicle. In order to prevent small overlap frontal collision accidents from causing death of occupants in the vehicle, the United States took the lead in researching and developing a 25% small overlap offset crash test condition, which is extremely strict to examine the structure of the passenger compartment of the crash test vehicle and the damage value of the dummy inside the vehicle. China has also formulated a corresponding crash test regulatory system, and will also require auto companies to pass the small ov...

AI Technical Summary

Problems solved by technology

The defect that this automobile small offset crash test barrier exists; One is that its rigid body wall 6 is made of reinforced concrete, and its quality is greater than 7*10 4 kg, very heavy, the energy consumed to raise the bottom of the inflation and make it move horizontally is relatively large, and the inflation structure is relatively complicated

The 2nd, the rigid body wall 6 is usually fixed on the end of the track 7 and the rear of the rigid barrier body assembly 1. After the test car 8 collides, if it cannot continue to move freely along the route of the collision, it may collide with the rigid body. The collision of the wall 6 caused other damage to the test vehicle 8 due to the secondary collision, and there was a great potential safety hazard

This in turn leads to higher costs
