Collision energy absorption mechanism and vehicle

Abstract

The invention relates to a collision energy absorption mechanism and a vehicle. The collision energy absorption mechanism comprises a fixed support and an energy absorption device installed on the fixed support; the fixed support is made of a metal material; the energy absorption device comprises an energy absorption plunger and a shell; the shell comprises an inner wall and an outer wall which are oppositely arranged, and a side wall is connected between the inner wall and the outer wall; the side wall, the inner wall and the outer wall jointly define a closed hydraulic chamber; one end of the energy absorption plunger is telescopically connected to the interior of the hydraulic chamber and is used for dividing the hydraulic chamber into two cavities, the other end of the energy absorption plunger is arranged outside the hydraulic chamber in a protruding mode, and the energy absorption plunger is provided with a buffer structure capable of enabling oil in the hydraulic chamber to circulate between the two cavities. When oil liquid circulates between the two cavities, kinetic energy is converted into heat energy, collision energy is consumed, and therefore the buffering and energyabsorbing effects can be achieved, and the risk that the life safety of passengers is injured is reduced.

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.
