Energy absorber for vehicle anti-collision equipment

Abstract

The present invention provides a vehicle -anti -collision equipment energy absorber, including the frame and the shell covered by the frame; the framework is installed as a combination of supporting parts to keep the energy suction unit. There are several energy -absorbing units and several energy -absorbing units replace modules. The structural design is reasonable, and the processing and assembly are simple. At the same time, the overall energy absorption effect is good. The shell is used to protect the internal components. The absorbing tube will be damaged first when the stress cap is impacted. The absorbent tube in the absorbent component is made of aluminum -magnesium alloy. The weight is light, which effectively reduces the weight of the car's anti -collision equipment. The energy -absorbing component can resist slight collisions, and when its external force impact reaches a certain limit, it will be stable. It can be disassembled or installed according to actual needs to disassemble or install the energy -absorbing unit replacement module that has reached the required absorption buffer effect.

Description

technical field [0001] The invention belongs to the technical field of vehicle-mounted anti-collision equipment, and in particular relates to an energy absorber for vehicle anti-collision equipment. Background technique [0002] In recent years, traffic accidents of hazardous chemical transport vehicles are common. How to ensure the traffic safety of hazardous chemical transport vehicles has become the top priority of the public security traffic police, traffic, safety supervision and other departments. Currently, hazardous chemical transport accidents account for the total traffic accidents. The proportion of hazardous chemical accidents is not high, but the damage results show an expanding trend. Statistics show that the fatality rate of hazardous chemical accidents is 33%, which is about 12 to 13 percentage points higher than the fatality rate of ordinary accidents. After the rear-end collision accident of a transport vehicle, it is more difficult to unload hazardous chem...

Problems solved by technology

At present, the structural strength of automotive energy-absorbing devices on the market is not high, there is no reasonable layout, and the energy-absorbing effect is not good, especially for vehicles transporting hazardous chemicals with a large load, they cannot absorb well when they are hit. Energy, the effect is very small, if you want to improve the buffer energy-absorbing effect, you can only make a large-scale buffer energy-absorbing device with a large volume and complex structure, which not only increases the self-weight of the vehicle too much, but also because the buffer energy-absorbing device is installed on the vehicle Therefore, the turning radius of the vehicle is also increased, making it difficult to drive and there are unsafe factors
