Serial connection type energy absorption component allowing elasticity buffering and plastic buckling

Abstract

The invention relates to a serial connection type energy absorption component allowing elasticity buffering and plastic buckling. The serial connection type energy absorption component comprises a cylindrical thin wall part and a compression spring. The serial connection type energy absorption component is characterized in that one end of the compression spring is fixedly connected with one end of the cylindrical thin wall part, the other end of the cylindrical thin wall part is a fixedly mounted end, and the other end of the compression spring is a stressed end. A mounting plate is arranged at the fixedly mounted end of the cylindrical thin wall part, the compression spring is fixedly connected with the cylindrical thin wall part through a connecting plate, and a bearing plate is arranged at the stressed end of the compression spring. The serial connection type energy absorption component disclosed by the invention has the benefits of being simple in structure, having functions of buffering and energy absorption, and improving safety protection performance.

Description

technical field [0001] The invention relates to the technical field of cushioning and energy absorption, in particular to an elastic cushioning and plastic buckling series 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. Because collision accidents will cause heavy personal casualties and property losses, collision problems have 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 u...

AI Technical Summary

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
