Anti-collision equipment energy absorber for vehicle

Abstract

The invention provides an anti-collision equipment energy absorber for a vehicle, which comprises a frame and a shell coated outside the frame, wherein a plurality of support members are combined and installed to form an energy absorption unit retainer in the frame, and a plurality of energy absorption units and a plurality of energy absorption unit replacement modules are installed on the energy absorption unit retainer. The energy absorber provided by the invention is reasonable in structural design, simple in processing and assembly and good in integral energy absorption effect; the shell is used for protecting all internal assemblies; the frame is used for fixing the energy absorption unit retainer formed by combining and installing a plurality of support members; energy absorption pipes in the energy absorption assemblies are damaged prior to compression resistant caps when being impacted; the energy absorption pipes in the energy absorption assemblies are made of aluminum-magnesium alloy which is light in weight, thereby effectively reducing the weight of the vehicle-mounted anti-collision equipment; the energy absorption assemblies can resist slight collision, and when the external impact to the energy absorption assemblies reaches a certain limit value, the energy absorption assemblies can stably collapse; and the energy absorption unit replacement modules can be disassembled or assembled according to actual requirements so as to achieve the required energy 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
