Problems solved by technology

But this patent has the following problems: ①During the collision process, since the number of nozzles participating in the injection is constant, the test results show that the speed curve of the motor vehicle body is a half-width sinusoidal curve, and the piston advances about 2/3 of the distance and consumes 92% of the engine power. The kinetic energy of the motor vehicle, the remaining 1/3 of the distance only consumes 8% of the kinetic energy of the motor vehicle, which is manifested in the excessive peak pressure of the liquid in the tubular stringer and the peak acceleration of the vehicle body. The problem to be solved is to reduce the peak pressure and acceleration peak
This is because when a frontal collision occurs, the front piston has already extended into the bottom of the front piston cylinder. At this time, a rear-end collision occurs. When the rear piston is pushed forward, the front piston will also move forward at the same time, and the reset process of the front piston will consume almost no energy. Any energy, the pressure of the liquid in the tubular stringer cannot be established, and the nozzle type energy consumption device and the piston type energy consumption device cannot function at this time. crush casualty
③When the motor vehicle collides at a very high speed, the propulsion distance of...

Description

technical field [0001] The invention relates to a motor vehicle collision device, in particular to a motor vehicle collision device with a jet energy consumer. Background technique [0002] Since the advent of motor vehicles in 1886, while bringing convenience to human life and work, road traffic accidents have also caused a large number of casualties and property losses. So far, more than 34 million people have died in car accidents worldwide, while hundreds of millions of people have been injured or disabled. According to the "Global Status of Road Safety" report published by the World Health Organization (WHO) on June 15, 2009, the number of deaths involving road traffic accidents in 2008 was as high as 1.2 million, and 20 to 30 million were injured or disabled. The annual economic loss caused by traffic accidents exceeds 700 billion US dollars. [0003] The body of the existing motor vehicle is in a compressed state during the collision process. On the one hand, this w...
