Collision energy dissipation component based on magnetorhrologic grease and device

Abstract

The invention relates to a collision energy dissipation component based on magnetorhrologic grease and a device; the collision energy dissipation component comprises an oil sac and an oil cylinder which are sequentially arranged along the axial direction vertical to a bumper rail, the closed and of the oil sac is arranged on the back surface of the bumper rail, the opening end thereof is communicated with the oil cylinder, and damping material is filled in the oil sac and the oil cylinder; a multi-level radial annular damping channel is arranged in the oil cylinder along the axial direction; in the invention, the oil sac communicated with the oil cylinder is arranged in front of the oil cylinder, and a linear type damping channel is changed into the multi-level radial annular damping channel, the effective length of the damping channel is increased and the dissipation ability of a collision energy dissipation device to collision energy is enhanced; the invention adopts the damping channel formed by an annular damping segregation board and a central segregation board, the structure is simple and the operation is convenient.

Description

Technical field [0001] The present invention involves a shock absorption device, especially about a collision energy dispersion component and device based on a magnetic flow -based lipid -based collision energy dispersion component and device that reduces the damage and the damage of car items in the car. Background technique [0002] With the rapid development of the automotive industry, the number of cars is increasing day by day, and the occurrence of traffic accidents is unavoidable.In various types of traffic accidents, the collision accident is the first place, so the safety requirements for collision of cars are getting higher and higher.In order to reduce the damage of the collision accident and effectively ensure the personal safety of members, countries around the world are actively conducting research on collision prevention.At present, the safety design of the anti -collision device is mainly concentrated at the moment when the collision occurs. The energy generated b...
