High-efficiency rollover preventing system for passenger car

Abstract

The invention relates to the technical field of passenger car safety protection, in particular to a high-efficiency rollover preventing system for a passenger car. According to the high-efficiency rollover preventing system disclosed by the invention, the inclination angle of a car body is sensed by an inclination angle sensor arranged in the gravity position of the car body; in the travelling process of the passenger car, when the inclination angle of the car body exceeds a set critical angle, a command of opening baggage cabin doors is transmitted to a cabin door ejecting mechanism arranged between each baggage cabin door and the car body through a controller; and each baggage cabin door which touches the ground before the car body absorbs a part of impact energy in advance through a triangular structure consisting of a car body breast beam lower stand column, a cabin door stand column hinged to the car body breast beam lower stand column, and a folding pull rod of which the two ends are respectively hinged to the car body breast beam lower stand column and the cabin door stand column, so that the touchdown deformation of a car body structure is buffered and reduced, and the effect of protecting the living space of occupants is achieved. According to the high-efficiency rollover preventing system disclosed by the invention, a conventional car body structure can be better utilized, and the rollover preventing property of the passenger car is improved through an active manner.

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
