Lifesaving airbag for automobile falling into water

Abstract

The invention relates to a lifesaving airbag for an automobile falling into water. The lifesaving airbag comprises a shell, a liquid storage chamber, a reaction chamber, an air bag, a large spring, alarge piston, mixed liquid, a small piston, an ejector rod and a blocking rod; the liquid storage chamber is communicated with the reaction chamber through a first connecting pipe; the reaction chamber is communicated with the air bag through a second connecting pipe, a flow guide pipe is arranged in the reaction chamber and placed in the reaction chamber, one end of the flow guide pipe is connected with the first connecting pipe, the other end of the flow guide pipe is closed, a certain number of small holes are formed in the flow guide pipe, and sodium peroxide and manganese dioxide powder are contained in a cavity between the reaction chamber and the flow guide pipe; the front section of the breathing tube is inserted into the air bag, a protective sleeve is connected to the breathing tube, and latticed air holes are formed in the outer end face of the protective sleeve. According to the lifesaving air bag for the automobile falling into water, after the automobile falls into water,the air bag provides oxygen for people falling into water, meanwhile, the air bag provides buoyancy for people falling into water, and the two problems that people escape and swim ashore in an existing falling-into-water accident are solved.

Description

technical field [0001] The invention relates to a rescue air bag for automobiles falling into water. The utility model belongs to the technical field of vehicle accessories. Background technique [0002] The fatality rate of automobile falling into water accident is much higher than that of other types of traffic accidents. After analyzing a large number of accidents, it is found that escaping from the vehicle and swimming ashore are two key problems to be solved. [0003] There are such products in the market, such as the invention patent with application number 201711128977.1, which discloses a blasting escape device for automobile glass windows, which includes a blasting hammer, a gunpowder chamber, a protective cover and an arc pulse device, which can blast in a directional manner and smash the glass windows , fast, safe and reliable; another example is the invention patent application number 201610903673.7, which discloses an airbag power-assisted disengagement device ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned patents are mainly on the car windows or the roof cover, but it is found from the accident cases that the above-mentioned technical solutions cannot completely solve the accident problem. If the vehicle rolls over or buckles upside down, the above-mentioned technical solutions are useless. It was an accident in which two people drowned in a water depth of only 0.5 meters. Because the vehicle was buckled upside down in the water, the occupants drowned before they could untie their seat belts.

[0005] The multiple technical solutions mentioned above cannot fundamentally solve the problem of people who cannot swim. There is a case listed as: After the car fell into the water, the husband fled to the shore by himself. Because he couldn’t swim, he watched his wife and two children drown. ACCIDENT
