A vehicle collision energy dissipation device

Abstract

The invention belongs to the technical field of vehicle safety, and in particular relates to a vehicle collision energy dissipation device. The invention comprises a crossbeam, on which a pair of fixed columns are arranged, the impact plate is slidably connected to the cylinder through a connecting rod, an energy dissipation plate is arranged between the two fixed columns, and a breaker with a cutting edge facing the energy dissipation plate is arranged in the middle of the impact plate. board knife. When the vehicle collides violently, the impact plate is impacted and close to the energy dissipation plate, driving the breaking knife to cut to the energy dissipation plate, offsetting most of the impact force during the cutting process, and there are multiple sets of elastic elements between the rigid parts to further buffer To counteract the huge kinetic energy in the fierce collision process, the impact plate is equipped with a buffer body composed of elastic plates and flexible plates, which can also provide active safety protection for pedestrians. The technical scheme of the invention can provide reliable products for the technical field of driving safety, can effectively protect people's life and property safety, and has great promotion value and application prospect.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a vehicle collision energy dissipation device. Background technique [0002] The original meaning of a vehicle refers to a car that has no power itself. It is called a carriage if it is pulled by a horse, and it is called a rickshaw if it is pulled or pushed by a human. With the development of science and technology, there are cars that are pulled by a steam engine, etc. Until now, the automobile industry The development is becoming more and more mature, the number of vehicles on the road is increasing, and the accident rate is increasing simultaneously. [0003] The injuries caused can be roughly divided into deceleration injuries, impact injuries, crush injuries, crush injuries, and falls, among which deceleration injuries and impact injuries are the most common. The deceleration injury is caused by the sudden and powerful deceleration of the vehicle. The impact injury ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, foam layers are usually used as collision energy dissipation devices at the front and rear of vehicles to protect pedestrians, passengers, and vehicles, and some are equipped with rigid settings such as bumpers and anti-collision beams to resist large impacts , but because the collision occurs in a very short time during the collision of the car, which leads to a huge instantaneous impulse at the moment of the collision, especially in a serious and violent collision accident, the existing buffer device is far from being able to deal with the collision at the moment of collision. Energy is absorbed, which leads to unsatisfactory anti-collision effect and insufficient protection for the vehicle and the occupants
