Elastic buffering and plastic overturning parallel type energy absorption assembly

Abstract

The invention relates to an elastic buffering and plastic overturning parallel type energy absorption assembly which comprises a cylindrical thin-wall component and a compression spring and further comprises an overturning seat. The elastic buffering and plastic overturning parallel type energy absorption assembly is characterized in that the center of the compression spring and that of the cylindrical thin-wall component are arranged on a same straight line; the overturning seat comprises a seat body and a boss, the boss is integrally in circular arc connection with the seat body, one end of the cylindrical thin-wall component sleeves the boss, and the other end of the cylindrical thin-wall component is a free end; one end of the compression spring is fixedly connected with the boss, the other end of the compression spring is a stress end, and the stress end extends out of the free end of the cylindrical thin-wall component. The invention has the benefits: the structure is simple, buffering and energy absorption functions are achieved, and safety and protection property are improved. Compared with a plastic collapse buckling energy-absorption structure, the structure of the elastic buffering and plastic overturning parallel type energy absorption assembly has longer buffering distance and more stable energy absorption capacity.

Description

technical field [0001] The invention relates to the technical field of cushioning and energy absorption, in particular to an elastic cushioning and plastic flipping parallel energy-absorbing component. Background technique [0002] With the continuous development of automobiles, high-speed trains and other vehicles and the continuous improvement of their operating speeds, their collision safety has attracted more and more attention. Issues that must be considered when designing trains and other structures. Another important issue in automobiles and high-speed trains is cushioning. But when an object is subjected to a slight collision or bump, the cushioning component can effectively reduce vibration and reduce the acceleration of the collision. The important difference between energy absorption and cushioning is that the deformation formed by energy absorption often uses the non-recoverable deformation characteristics of the structure to absorb energy, while cushioning uses...

Problems solved by technology

At present, the structure of buffer devices used in vehicles is relatively simple, such as springs or hydraulic cylinders. When an accident occurs, it is necessary to quickly slow down the impact energy, and even when the safety components are damaged in exchange for personal safety, these buffer devices are still incompetent. The energy-absorbing parts can not reflect the buffering effect in normal operation, and the functions of the energy-absorbing parts and the buffering parts are not well integrated
