Problems solved by technology

However, the current mainstream energy-absorbing devices are still some common configuration pipes, such as thin-walled square tubes, thin-walled round tubes, etc., which can no longer meet people's many requirements for safety and anti-collision structures. Therefore, a new type of energy-absorbing device is designed to improve safety, has important practical significance and practical value

Abstract

The invention discloses a collision energy absorbing device based on a paper folding structure, which comprises a folded outer box body, a folded inner box body and two flange connecting pieces, the inner box body is coaxially arranged in the outer box body, the two flange connecting pieces are fixedly connected to the two ends of the outer box body and the two ends of the inner box body respectively, a first honeycomb body is filled between the outer box body and the inner box body, and the inner box body is filled with a second honeycomb body. The collision energy absorbing device has the advantages of high energy absorption efficiency, stable energy absorption process, small initial peak force, capability of ensuring multi-angle collision energy absorption, simple structure and easiness in manufacturing.

Description

technical field [0001] The invention relates to a collision energy-absorbing device, in particular to a collision energy-absorbing device based on an origami structure. Background technique [0002] With the development of science and technology, the progress of industry, and the significant improvement of people's living standards, the travel rate of people in various countries is increasing. While enjoying the convenience brought by the means of transportation, people have also suffered from various traffic accidents that emerge in an endless stream, causing great property losses and safety problems to the society and the people. As a long-standing global problem, traffic safety has been paid more and more attention to by people. As an important energy-absorbing element during a collision, the energy-absorbing device absorbs the kinetic energy from the collision accident through its own irreversible crush deformation, so as to protect the occupant or the victim. However,...
