Crash absorbers and vehicles

Abstract

The present disclosure relates to a crash energy absorbing mechanism and a vehicle, comprising a fixed bracket and an energy absorbing device installed on the fixed bracket, the fixing bracket is made of metal material, the energy absorbing device includes an energy absorbing plunger and a housing, The housing includes an inner wall and an outer wall oppositely arranged, and a side wall connected between the inner wall and the outer wall, the side wall, the inner wall, and the outer wall together form a closed hydraulic chamber, and the energy-absorbing One end of the plunger is telescopically connected to the inside of the hydraulic chamber and divides the hydraulic chamber into two chambers, and the other end protrudes outside the hydraulic chamber, and the energy-absorbing plunger is provided with A buffer structure that enables oil in the hydraulic chamber to communicate between the two chambers. When the oil circulates between the two chambers, it converts the kinetic energy into heat energy and consumes the energy of the collision, so that it can play the role of cushioning and absorbing energy and reduce the risk of injury to the life safety of the occupants.

Description

technical field [0001] The present disclosure relates to the field of anti-collision of vehicles, in particular, to a collision energy-absorbing mechanism and a vehicle. Background technique [0002] At present, the number of automobiles in my country is growing rapidly, and the incidence and death rate of traffic accidents are also high. Under the situation of increasing collision energy, the traditional method of simply relying on the plastic deformation of steel plates to absorb collision energy has certain limitations, which not only leads to the death of occupants The safety is greatly damaged, and at the same time, after a slight collision of the vehicle, it is difficult to repair the vehicle, the cost of vehicle maintenance is high, and social resources are wasted. However, due to the constraints of materials, technology, weight and cost, it is impossible to improve the anti-collision ability by arranging the reinforcement plates indefinitely and improving the strength...

[0002] At present, the number of automobiles in my country is growing rapidly, and the incidence and death rate of traffic accidents are also high. Under the situation of increasing collision energy, the traditional method of simply relying on the plastic deformation of steel plates to absorb collision energy has certain limitations, which not only leads to the death of occupants Safety is greatly damaged, and at the same time, after a slight collision of the vehicle, it is difficult to repair the vehicle, the cost of vehicle maintenance is high, and social resources are wasted

However, due to the constraints of materials, technology, weight and cost, it is impossible to improve the anti-collision ability by arranging reinforcement plates indefinitely and improving the strength of parts materials.
