Embodiment 1

[0010] Embodiment 1: Multiple springs (2) can be installed between the top of the rod of the piston (3) and the bearing plate (1).

Embodiment 2

[0011] Embodiment 2: An oil-inlet check valve (7) and a pressure relay or pressure sensor (8) are installed on the bottom side wall of the cylinder. Connected with the control circuit and the pump, it can form an automatic oil filling device. It is connected with the ignition device of the control vehicle to form a flameout device, and the vehicle is flamed out after a collision. Protect the car.

Embodiment 3

[0012] Embodiment 3: add a high-pressure pipe after the one-way valve (6), or add a high-pressure pipe after the one-way valve (6) and the one-way valve (7), and the liquid of several collision relief safety devices is fed by a pump Injection, the liquid flows out into a liquid storage container when the crash evacuation safety device works.

Abstract

The collision load-releasing safety device is a safety protection one used when the collision takes place by high-speed vehicle (automobile, ship and train), which comprises a cylinder with piston and filled with liquid, the bottom portion of the cylinder is equipped with several small conical holes on the periphery of which the non-return valve is mounted, the top end of the piston rod is equipped with spring, and the other end of the spring is equipped with force-bearing plate. When the collision takes place, the spring can be compressed to absorb partial kinetic energy which can be converted into elastic energy to make the liquid jetted out to convert a part of kinetic energy into friction heat energy and released partial energy.

Description

1: Technical field [0001] The invention belongs to the technical field of collision safety, especially in the collision of high-speed moving objects, especially automobiles, ships, trains, etc., and the object itself is extremely related to the safety. Two: background technology [0002] Take a car as an example, assuming that the mass is one ton and it is traveling at a speed of 80 kilometers per hour. After a collision, the speed is 0, and the negative work displacement during the collision is 10 cm. The force on the car is about 200 tons. Traveling at a speed of 40 kilometers, the suffered force is about 50 tons. (According to 1 / 2mv*v=fs) when colliding, the displacement may be smaller and the stressed force will be larger. It can be seen that the high-speed moving object receives a huge force after collision, and its destructive force is also very large. With the increase of highways and automobiles, high-speed collisions of vehicles also increase, and their harm is als...
