Description
Technical Field
The utility model relates to a car lifesaving gasbag that falls into water. Belongs to the technical field of vehicle accessories.
Background
The death rate of the automobile falling into water accidents is far higher than that of other types of traffic accidents, and after a large number of accidents are analyzed, two key problems to be solved are found to be escaping from the automobile and going to the bank during swimming.
The conventional product in the market, for example, the invention patent with the application number of 201711128977.1 discloses an automobile glass window blasting escape device, which comprises a blasting hammer, a explosive bin, a protective cover and an electric arc pulse device, can be used for directional blasting and breaking the glass window, and is quick, safe and reliable; another example is the invention patent with application number 201610903673.7, which discloses an airbag-assisted detachment apparatus for an automotive front windshield, comprising an airbag controller, a squib pull-tab, and an airbag; personnel in the vehicle can detonate the safety airbag to push the front windshield open to escape; the invention further discloses a life-saving car body device of a household car, as the patent of the invention with the application number of 201810856578.5, which comprises a top cover and an air bag, wherein the top cover is tightly connected with the car body through a lock pin plate and a hole head bolt, the top cover can be separated from the car body instantly, an escape channel of the top cover is opened, so that a driver and passengers can conveniently escape, and the air bag and the top cover form a ship-shaped structure after being unfolded, so that the life-saving car body device can be used as a life boat.
The above patents are mainly made on windows or roofs, but it is found in the case of accidents that the above technical solutions cannot completely solve the accident problem, and if the vehicle turns over or the above technical solutions are reversed, there is a case of an accident that two persons are drowned in a depth of only 0.5 m, because the vehicle is reversed in water, the passengers are drowned in time to unfasten the safety belts.
The technical schemes cannot solve the problem that the person cannot swim at all, and one scheme is as follows: after the automobile falls into water, a husband can escape to the bank by himself, and the husband can not swim, so that the eyes of the husband can be opened to see a wife and two children are drowned.
In conclusion, in order to fundamentally reduce the death rate of the car falling into water accident, the two aspects of escaping the car and going to the bank for swimming must be considered; the escape vehicle and the escape process ensure that the oxygen is supplied as the first step, the swimming to the bank or floating on the water surface to wait for rescue is the second step, and only the two problems are solved, the mature scheme of the lifesaving device is realized.
