Side overturning crash cushioning device of passenger car and application method thereof

Abstract

The invention discloses a side overturning crash cushioning device of a passenger car and an application method thereof. The technical scheme of the invention is as follows: a sensor, a receiver, a window buckle switch, a lock pin switch, a window net, a lock pin, an internal pad, an external pad and a clamping hole are arranged at the corresponding parts of the passenger car. When the wheels at one side of the passenger car are wholly hung in the air and about to overturn, a sensing signal is sent to the receiver by the sensor; then the related devices are started by the receiver; the window net is opened so as to protect passengers in the passenger car so that the bodies of passengers, particularly the heads, are protected to prevent direct collision with the ground; and meanwhile, the external pad at the top of the passenger car is popped up and contacted with the ground when the passenger car overturns so as to greatly reduce the impact force between the body of the passenger car and the ground and increase the friction between the body of the passenger car and the ground, so that the body of the overturned passenger car slides for a shorter distance. Through the invention, the shortcomings of the similar technology at prevent are overcome; and the technical design of the invention reaches the advanced international standards.

Description

technical field [0001] The invention relates to a buffer device, in particular to a passenger car rollover buffer device for reducing the impact force between the vehicle body and the ground and shortening the sliding distance when the passenger car rolls over, and an application method thereof, belonging to the field of mechanical engineering. Background technique [0002] Bus is an important means of transportation for modern people. With the growth of global population and the rapid development of highways, the role of passenger cars has become more and more important. It is the preferred means of transportation for people to travel and travel, but it is accompanied by frequent traffic accidents. Especially on the expressway, once a rollover accident occurs to the passenger car, due to the high speed, the passenger car will often slide 20-30 meters on the road after the rollover. Sliding; causing the head of the passenger to smash the window glass and then collide and ru...
