Abstract

The invention discloses an automotive vehicle collision device with a novel switch type jetting energy dissipater, which comprises a piston cylinder, a screw hole joint, a high pressure connection tube and the novel switch type jetting energy dissipater, wherein the novel switch type jetting energy dissipater comprises a high pressure buffer chamber, a low pressure buffer chamber, a pedestal jetting hole, an upper part valve cylinder, a middle part valve cylinder, a lower part valve cylinder, an upper part shuttle valve, a middle part shuttle valve and a lower part shuttle valve; the pedestal jetting hole penetrates from the middle part valve cylinder to the low pressure buffer chamber; a liquid channel is arranged between the middle part valve cylinder and the middle part shuttle valve; a liquid channel is arranged between the lower part valve cylinder and the lower part shuttle valve; and each shuttle valve assembly can vertically shuttle according to a pressure difference between the upper end and the lower end, so that the corresponding liquid channel between the lower part valve cylinder and the lower part shuttle valve is closed. According to the automotive vehicle collision device with the novel switch type jetting energy dissipater, the contact strain problem and the loss problem of wires between the shuttle valve and the valve cylinder can be solved, the automotive vehicle can be ensured to have a bidirectional anti-collision function, and the automotive vehicle body can be ensured to be always in a stretching state.

Description

technical field [0001] The invention relates to a motor vehicle collision device, in particular to a motor vehicle collision device with a novel switch-type injection 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....
