Abstract

The invention discloses a motor vehicle chassis with an anti-collision device. The motor vehicle chassis comprises a tubular longitudinal beam, a piston cylinder, a piston, a piston mandril, a pressure relief tube, a piston cylinder end cover, an anti-collision rod and energy dissipation liquid, wherein one end of the piston cylinder is fixedly connected with the tubular longitudinal beam, and the other end is connected with the piston cylinder end cover; one end of the piston mandril is connected with the top of the piston, and the other end penetrates through the piston cylinder end cover to connect the anti-collision rod; the energy dissipation liquid is filled in the tubular longitudinal beam and the piston cylinder; the pressure relief tube is reserved on the piston cylinder; the piston is provided with at least one jet hole; the jet hole penetrates from the bottom of the piston to the top of the piston, so the tubular longitudinal beam is in a stretched state in an anti-collision process so as to prevent a passenger room from being extruded and deformed and prevent a steering column and a steering wheel from moving backwards to smash the heads and the chests of a passenger. Therefore, the security of a motor vehicle can be improved extremely.

Description

Technical field

[0001] The invention relates to an active anti-collision method and device for a motor vehicle, in particular to a motor vehicle chassis with an 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 people 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. Annual economic losses due to road traffic accidents exceed $700 billion.

[0003] The body of the existing motor vehicle is in a compressed state during the impact process....
