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 dr

Embodiment Construction

[0020] The present invention is described in further detail below in conjunction with the embodiment given with accompanying drawing.

[0021] Such as figure 1 , 2 Shown in the figure: 1 is the column under the waist beam of the vehicle body, 2 is the door column, 3 is the folding pull rod, 4 is the door crossbeam, and 5 is the hinge; Actively pop open the luggage compartment door mechanism when turning over, so that it collides with the ground before the body, and absorbs the impact energy for the body structure through the collision deformation of the luggage compartment door itself, so as to reduce the deformation of the body structure and protect the living space of the occupants Its specific implementation is as follows: the signal of the contact switch at the parking brake place is received by the controller 7, and when the vehicle is running, the controller closes the two-position two-way electromagnetic valve 17 positioned at the outside of the pop-up cylinder to ens...

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...
