Problems solved by technology

However, due to the cost and the problem of particle settlement in the magnetorheological fluid itself, the magnetorheological damper has not been widely used in civilian vehicles at present, and most of them are used in some high-end vehicles and military equipment, and the current magnetorheological The damper cannot be adaptively adjusted according to the characteristics of the car when it collides, which has great limitations

Abstract

The present invention provides an automobile collision buffer system based on magnetic control cement, comprising: a buffer capsule filled with magnetic control cement and a magnetic buffer pressure relief device, the buffer capsule is installed on the outside of the automobile anti-collision baffle, and the magnetic buffer The pressure relief device is in sealing communication with the magnetic buffer capsule. The invention effectively divides the automobile collision buffer device into three extrusion flow buffers, which can be applied to collisions at different speeds; the multi-baffle structure effectively increases the circulation damping of the three-stage controllable magnetic control cement in a small volume The length of the channel enables the device to absorb the collision energy to the greatest extent and greatly reduce the damage of the car to the driver and passengers when a collision occurs.

Description

Technical field [0001] The present invention relates to the technical field of automobile collisions, in particular to an automobile collision buffer system based on magnetic control cement. Background technique [0002] In recent years, with the rapid increase in the number of automobiles in my country, traffic safety has become a very important topic. Passive automobile safety technology, as the top priority, is the only guarantee to prevent drivers and passengers from being injured or even killed. When a car has a frontal collision, the front buffer energy-absorbing assembly is mainly used to absorb the kinetic energy of the collision and reduce the impact force. At present, most automobile energy-absorbing energy-absorbing devices are mainly purely mechanical structures, pneumatic or hydraulic methods designed for the specific collision intensity of automobiles. These methods have gradually failed to meet people's needs for automobile safety. With the development of science a...
