Safe protecting method and device for rollover of coach

Abstract

The invention relates to the technical field of safety protection of coaches and particularly relates to a safe protecting method and a device for the rollover of a coach. The inclination angle of a coach body is sensed by an inclination sensor arranged at the gravity center of the coach body; when the inclination angle of the coach body of the coach exceeds a set clinical angle during driving, an instruction is transmitted to a compartment door ejecting mechanism arranged between a luggage compartment door and the coach body by the controller to open the luggage compartment door; the luggagecompartment door grounded ahead of the coach body absorbs a part of impact energy through a triangular structure consisting of a lower upright post of a coach body waist beam, a compartment door upright post hinged with the lower upright post of the coach body waist beam and a folding pull rod of which two ends are respectively hinged to the lower upright post of the coach body waist beam and thecompartment door upright post, so that the grounded deformation of a coach body structure is buffered and reduced and the function of protecting the living space of passengers is achieved. According to the safe protecting method and the device disclosed by the invention, a traditional structure of the coach body can be better utilized and the rollover resistance of the coach is improved by adopting an active mode.

Description

technical field [0001] The invention relates to the technical field of passenger car safety protection, in particular to an anti-rollover safety protection method and a safety protection device for realizing the method. 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 of "Regulations on the Stren...

AI Technical Summary

Problems solved by technology

The above scheme not only increases the weight of the body structure, but also does not significantly improve the safety of the passenger car rollover, which makes the strength of the body structure far greater than the strength during normal driving, which is not conducive to energy saving and emission reduction and lightweight design of the body

Due to the limitation of the structure of the traditional passenger car, the energy-absorbing structure cannot be added outside the side wall.
