High-efficiency rollover preventing system for passenger car

Abstract

The present invention relates to the technical field of passenger car safety protection, in particular to a high-efficiency anti-rollover system for passenger cars. The inclination angle of the vehicle body is sensed by an inclination sensor arranged at the center of gravity of the vehicle body. When the inclination angle of the vehicle body exceeds a set critical When the angle is at an angle, the controller sends an instruction to the door pop-up mechanism installed between the luggage compartment door and the vehicle body to open the luggage compartment door. The triangular structure composed of the connected hatch column and the foldable tie rods hinged at both ends to the lower column of the waist beam of the vehicle body and the door column respectively absorbs part of the impact energy in advance to buffer and reduce the ground deformation of the body structure and protect the survival of the occupants. The role of space. The invention can make better use of the existing structure of the vehicle body, and actively improve the anti-rollover performance of the passenger car.

Description

technical field [0001] The invention relates to the technical field of passenger car safety protection, in particular to an efficient anti-rollover system for passenger cars. Background technique [0002] With the development of society, people pay more and more attention to the safety of automobiles, and passenger cars, as the main public transportation means in modern society, are paid more and more attention to their safety. In all traffic accidents, passenger car rollover often leads to heavy casualties, which is a major traffic accident. Therefore, improving the anti-rollover ability of passenger cars and ensuring the safety of passengers in rollover accidents has become a very important topic. At present, the Economic Commission for Europe (ECE) has formulated a passenger car rollover regulation (ECE R66) and enforced it. In my country, referring to the ECE R66 regulations, the national standard "Regulations on the Strength of the Upper Structure of Passenger Cars" (G...

Problems solved by technology

[0003] In order to solve the problem that an effective energy-absorbing structure cannot be designed for the side wall of the passenger car during the rollover process of the passenger car, this invention proposes a high-efficiency anti-rollover system for passenger cars based on the requirements of the existing European ECE R66 regulations. On the basis of changing the original body structure, by adding a movable energy-absorbing mechanism to improve the rollover safety of the bus to realize the lightweight design of the body
