Abstract

The invention relates to a motor vehicle safety anticollision device, which comprises a piston-type jet energy consumption device and a pipe wall-type jet energy consumption device, wherein the piston-type jet energy consumption device comprises a piston cylinder, a piston, a piston ejector pin, a piston cylinder end cover, an anticollision rod and an antifreeze solution; the piston is provided with at least one piston jet hole; the piston jet holes penetrate through the top of the piston from the bottom of the piston; the pipe wall-type jet energy consumption device comprises at least one pipe wall jet hole, a jet buffer chamber, a jet buffer chamber pressure relief pipe, a connecting pipe and an antifreeze solution box. By adopting the motor vehicle safety anticollision device, a motor vehicle can be ensured to have a bidirectional anticollision function, i.e. the front collision is prevented firstly and then the rear-end collision can be prevented, the body of the motor vehicle can be ensured to be in the stretching state in the high-speed front collision process, the side collision prevention performance can be greatly improved and the safety of the motor vehicle can be greatly improved. The invention also relates to a motor vehicle chassis with the anticollision device.

Description

technical field [0001] The invention relates to a motor vehicle safety anti-collision device and a motor vehicle chassis with the anti-collision device. Background technique [0002] Since the advent of automobiles 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 involved in road traffic accidents in 2008 was as high as 1.2 million, and 20 million to 30 million people were injured or disabled. Global economic losses due to road traffic accidents exceed US$700 billion annually. [0003] The body of the existing motor vehicle is in a compressed state during the collision process. On the one hand,...

AI Technical Summary

Problems solved by technology

But this patent has the following problems: ① when the front of the motor vehicle collides first and then the rear-end collision occurs immediately, the motor vehicle body may be in a compressed state

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. With any energy, the pressure of the liquid in the tubular stringer cannot be established. At this time, the nozzle energy consumption device and the piston type energy consumption device cannot function. pressure casualties

②When the motor vehicle collides at a very high speed, the propulsion distance of the front piston ejector rod may be greater than the design distance. At this time, the anti-collision rod will directly impact on the end cover of the piston cylinder, which will cause the motor vehicle body to be in a compressed state, seriously may result in personal injury

③ No matter it is 100% full frontal collision or 70% offset collision, the number of nozzles participating in the injection is unchanged, and it is impossible to satisfy 100% full frontal collision and 70% offset collision at the same time

⑦The high-speed fluid sprayed from the nozzle will generate a relatively large impact force, which cannot be used in this patent to help the motor vehicle body to be in a stretched state

⑧ From the previous analysis, it can be seen that after a frontal collision, the front piston hardly consumes energy in the process of retreating, and the front piston resets without encountering resistance, which will easily lead to a relatively large rebound speed of the motor vehicle, which is not conducive to personnel protection

⑩The spring is too soft, and a light collision will cause the car body to deform, which is not conducive to industrial application; in addition, placing the spring at the bottom of the piston cylinder is not conducive to reducing the length of the piston cylinder, and is not conducive to industrial application
