Impact force mitigation device and vehicle

Abstract

The invention provides an impact force mitigation device. The impact force mitigation device comprises a front force mitigation device, wherein the front force mitigation device comprises a force-bearing body and a force guide energy absorption mechanism, the force guide energy absorption mechanism comprises a force-guiding body and an energy absorption device, one end of the force-guiding body isvertically connected to the force-bearing body and is behind the force-bearing body, the energy absorption device comprises N tooth-shaped steps and N-1 energy absorption contact blocks, the front end of each energy absorption contact block is connected with the force guide body, the tail end of each energy absorption contact block is in a clearance of two adjacent tooth-shaped steps in a one-to-one correspondence, wherein N is a positive integer greater than or equal to 2. Due to the force guide energy absorption mechanism, the action force is transmitted from the forced direction to an inverse direction and is converted into pull force, so as to form counter-acting force relative to the impact force, so that the inertia effect is reduced. When being applied to a vehicle, the impact force mitigation device needs to cooperate with a safety belt, and deformation of the force-bearing body due to impact force can be reduced to the greatest extent, for example, damage to drivers and passengers after collision and deformation of the vehicle is avoided.

Description

Technical field [0001] The invention relates to the technical field of impact mitigation, in particular to an impact mitigation device and a vehicle equipped with the impact mitigation device. Background technique [0002] Moving objects, especially vehicles, often collide due to various reasons during the movement. After the collision occurs, accidents often occur, causing safety hazards to the vehicle body and the passengers in the vehicle. In order to reduce the potential safety hazards caused by such collisions, the prior art usually adopts the method of installing bumpers on the vehicle to avoid the collision damage of the vehicle body and protect the safety of the passengers to a certain extent. [0003] However, when a high-strength impact is applied to the bumper, after the bumper is subjected to a force that exceeds its own strength, the force point of the vehicle directly acts on the forefront of the force point of the vehicle, forming a deformation of the vehicle body an...
