A vehicle falling into water escape device

Abstract

The invention discloses an escape device for an automobile falling into water. The escape device comprises an air bag and a high-pressure carbon dioxide gas storage steel cylinder communicated with the air bag through a first vent pipeline, wherein a first on-off valve is arranged on the first vent pipeline. The escape device for the automobile falling into the water further comprises a filter; sodium peroxide is stored in the filter; the filter is communicated with the high-pressure carbon dioxide gas storage steel cylinder through a second vent pipeline and / or the first vent pipeline; a valve is arranged at the air inlet end of the filter; the air outlet end of the filter is communicated with an automobile compartment; the high-pressure carbon dioxide gas storage steel cylinder is a dry-ice fire extinguisher. The escape device disclosed by the invention provides buoyancy for the automobile which falls into water, accidentally or caused by urban inland inundation, through the air bag, so that the driver and passengers have time to escape; in addition, the escape device provides short-time life support for the driver and passengers who cannot leave from the automobile in time or cannot normally open the air bag due to mechanical faults of the automobile; meanwhile, the problems of automobile fire, and accident impact before the automobile falls into the water are solved.

Description

technical field [0001] The invention relates to an escape device, in particular to an escape device for an automobile falling into water. Background technique [0002] In the prior art, due to the negligence of the driver or other reasons, accidental accidents of falling into the water often occur when the vehicle is running. Due to the large water level difference between the inside and outside of the falling vehicle, a large pressure is generated, which hinders the opening of the door, causing the occupants to be unable to Open the car door for a short time to escape. Therefore, once the car falls into the water, the people in the car are easily trapped in the car, and the pressure required to smash the windshield is even greater, which is not available to ordinary people, so it often causes casualties in the car. For example: On July 21, 2012, Beijing suffered the strongest rainstorm in 61 years. According to preliminary statistics, among the victims of this rainstorm in...

Problems solved by technology

For the first technical solution, because the reactant is unstable, the high-heat gas generated will burn the skin, and the safety is poor, so it is still in the practical stage and has not been really used in cars.

Although the second technical solution avoids the above-mentioned problems, there are still other safety problems when the car accidentally falls into the water, such as the lack of oxygen in the cockpit caused by the inability to leave the car in time or the failure of the airbag to open normally due to mechanical failure. The problem of car fire, and the accidental collision problem before the car falls into the water, the technical solution of the above invention still has the limitation that it cannot solve the above safety problems at the same time
