Side-turning safety protection device of passenger car with cabin door and airbag

Abstract

The invention discloses a side-turning safety protection device of a passenger car with a cabin door and an airbag. The side-turning safety protection device is composed of cabin door popup mechanisms (3) which are arranged on luggage cabin doors at the bottom parts of the two sides of the passenger car and are capable of enabling the cabin doors to open rapidly, a contact switch arranged at the place where a parking brake is located, and a dip angle sensor (1) and a controller (2) both of which are arranged at the position where the center of gravity of the car body is located, wherein the side-turning safety protection device further comprises safe airbag components (7) which are arranged at the inner sides of the passenger car luggage doors (6) at two sides; the cabin door popup mechanism (3) and the safe airbag component (7) are respectively connected with a signal output port of the controller (2); the dip angle sensor (1) and the contact switch at the place where the parking brake is located are respectively connected with a signal input port of the controller (2). The invention provides an improved side-turning safety protection device of the passenger car on the basis of the conventional passenger car structure to dedicate to the improvement of the side-turning safety of the passenger car and realization of light-weight design of the car body by adopting the upper-lifting type movable cabin doors and the safe airbag components on the basis of unchanging the original car body structure.

Description

technical field [0001] The invention relates to the technical field of passenger car safety protection, in particular to a safety protection device for passenger car rollover. technical background [0002] In recent years, with the continuous occurrence of bus accidents, people have paid more and more attention to the safety of bus collisions. Among all traffic accidents, passenger car rollovers often lead to heavy casualties, which are major traffic accidents. Therefore, it has become a very important subject to improve the anti-rollover performance of passenger cars and ensure the life safety of passengers in rollover accidents. At present, with reference to the Passenger Car Rollover (ECE R66) regulations formulated by the Economic Commission for Europe, my country has formulated the national standard "Regulations on the Strength of the Upper Structure of Passenger Cars" (GB / T17578-1998), and enforced it to improve the side resistance of domestic passenger cars.

AI Technical Summary

Problems solved by technology

Due to the limitation of the structure of traditional passenger cars, it is inconvenient to add energy-absorbing structures outside the side wall, so it is necessary to study a passenger car rollover protection device to improve the rollover safety of passenger cars
