Automobile active safety multi-layer and multi-set outer anti-collision airbag device

Abstract

The invention provides an automobile active safety multi-layer and multi-set outer anti-collision airbag device formed by assembling a multi-layer and multi-set front airbag, an extending airbag back, two side airbags, a rear airbag, a radar, a single-chip microcomputer, a signal connecting line, a gas distributor, gas conveying pipelines, multiple small gas bottles, airbag fixing devices and the like. The multi-layer and multi-set front airbag of an automobile is formed by connecting multiple independent airbag bodies. The front airbag is shaped like a barrel placed in an inverted mode from appearance. Each airbag body is made of macromolecule fiber shell fabric and a net. The size of the nets is smaller than that of the airbag bodies. The airbag bodies are shrunk in a vacuum mode. When the automobile travels at a high speed and is within a critical distance, the radar is started, the single-chip microcomputer transmits signals, the gas distributor is opened, gas in the small gas bottles enters airbag pipelines of independent outer, middle and inner layers of the gas distributor through pipelines, and is conveyed to the multiple layers of independent airbag bodies at the other end of the gas distributor, and the airbag body of the outmost layer of the multi-layer and multi-set front airbag and the extending airbag back are integrated; the airbag back is inflated to extend to a front windshield. The two side airbags and the rear airbag of the automobile are made of single-layer airbag bodies and nets. A control system is just like the front airbag.

Description

technical field [0001] The invention relates to an active safety vehicle protection device for automobiles and a pedestrian protection device. It is an active safety multi-layer multi-group airbag system protection device installed on the outside of the car. In particular, it relates to an automobile active safety multi-layer multi-group outer anti-collision air bag device. Background technique [0002] Active anti-collision airbags belong to the field of automobile safety technology. Most of the traffic accidents happen directly in front, and the speed of the vehicle and the sudden appearance of obstacles are the most direct factors of the accidents, which cannot be avoided by manpower alone. Cause damage and casualties to vehicles and personnel. Countries all over the world are doing a lot of research and testing on automotive safety technology.

[0002] Active anti-collision airbags belong to the field of automobile safety technology.

Damage and casualties to vehicles and persons

Countries all over the world are doing a lot of research and testing on automotive safety technology. However, at this stage, the front bumper of a car cannot protect the vehicle and people in the event of an accident. It can only be used as a decoration to make the car look better.

Although there is an airbag in the steering wheel, its anti-collision ability is limited. In a car collision accident, people directly bump into the exploding airbag, which will cause serious damage to the body, making it difficult to protect the driver inside the car and outside the car. The purpose of protecting the safety of vehicles and pedestrians, and it also frequently "vacates"

Usually, when a vehicle without an active safety system steps on the brakes, all four wheels are locked immediately. The wheels do not move at all, but the car is still sliding forward under the action of inertia. When it is unavoidable, the driver can only watch the accident happen.
