Energy-absorbing buffers, crash structures and vehicles

Abstract

The invention discloses an energy absorption buffering device, an anti-collision structure and a vehicle. The absorption buffering device comprises a casing, and a buffering piece which can be movably inserted in the casing along an axial direction, wherein first buffering areas accommodating first fluid media are formed between the buffering piece and the casing in a limit manner, a second buffering area accommodating a second medium is formed in the buffering piece, when the buffering piece is inserted inwards in the casing, the first fluid media can enter the second buffering area through a throttling structure between the first buffering areas and the second buffering area. When collision occurs, the buffering piece is prevented from being inserted in the casing through the moving damping and the resistance to compression of the first fluid media; when the collision is more heavy, the pressure of the first fluid media rises, and the first fluid media can enter the second buffering area through the throttling structure, so that the resistance to the buffering piece entering the casing is increased. Therefore, through the artful structure of the energy absorption buffering device disclosed by the invention, the effects of energy absorption and buffering can be effectively improved, and the practicability is high, so that the anti-collision property and the safety of the vehicle are higher.

Description

technical field [0001] The invention relates to the fields of energy absorbing, buffering and anti-collision components, in particular to an energy-absorbing buffer device, an anti-collision structure using the energy-absorbing buffer device and a vehicle using the anti-collision structure. Background technique [0002] At present, the number of vehicles is increasing, and the number of safety accidents is also increasing. By adding proper protection to the front of the car, the crash performance of the vehicle can be improved. When the vehicle collides, the protective device can play its role to reduce the degree of injury to the driver and passengers on the vehicle. At present, the protective device of an existing vehicle is usually a front bumper, and the skeleton of the front bumper is directly connected with the vehicle frame. However, due to the simple installation structure and insufficient rigidity of the front bumper, energy cannot be absorbed in the event of a co...

AI Technical Summary

Problems solved by technology

However, due to the simple installation structure and insufficient rigidity of the front bumper, energy cannot be absorbed in the event of a collision, but the collision force and energy are directly transmitted to the frame and body, resulting in deformation of the frame and body, endangering safety of people on board
