Emergency floating device for vehicle

Abstract

The invention relates to an emergency floating device for a vehicle. The emergency floating device comprises a shell, a manual bracing wire ring, a button switch, a valve, an electrolyte water level sensor, a bracing wire, a control circuit, an electromagnet, a valve lever, a connecting shaft, a compressed air bottle, a foldable airbag and a floating tank. The emergency floating device can be mounted on various vehicles; the emergency floating device does not occupy much more volume or weight at ordinary times, but the airbag can be popped up at the emergency moment of the vehicle falling into water. The emergency floating device provided by the invention has three starting modes; the emergency floating device can be automatically started after encountering with water and can be manually started, so that the practicability of the emergency floating device is guaranteed, and the reliability of the device is greatly promoted; the vehicle can float on the water surface, so that passengers can be prevented from being drowned; and the cost is low, the structure is simple, and the safety performance of various vehicles can be greatly promoted.

Description

technical field [0001] The invention relates to an emergency floating device for vehicles. Background technique [0002] Every year, a large number of people drown, vehicles fall into the water, ships sink, planes crash into the sea and other accidents, resulting in a large number of deaths. For example, the number of drowning deaths in my country reaches 57,000 people every year, 26 people died when a passenger car fell into the water in Tianjin, 442 people died when the Oriental Star sank, and 281 people died when the South Korea Sewol sank, and so on. All kinds of means of transportation are extremely lack of measures to deal with falling into the water, which often leads to the consequences of falling into the water and death. [0003] The existing Kingii personal drowning life-saving bracelet adopts a disposable carbon dioxide cylinder, a plastic folding airbag, an acupuncture valve, and a lever switch structure. Pull the lever, the valve will puncture the mouth of th...

AI Technical Summary

Problems solved by technology

When the car falls into the water, the water level sensor senses the water pressure and converts the static pressure into a resistance signal, so that the control circuit receives the signal, and then opens the electric valve, so that the gas in the carbon dioxide cylinder is filled into the airbag, and the airbag expands, making the car float on the water. On the water surface, relying solely on the triggering method of the sensor, once the sensor fails, the entire system will fail; or use sodium azide ignition and explosion to inflate the airbag, but the ignition and explosion of sodium azide is very unstable and may break through the airbag

In addition, the life-saving system is only for automobiles, and its scope of application is limited.

[0005] In addition, the existing design is only for the safety of the car falling into the water, and its size and shape are all designed for the car, which cannot provide protection for trucks, buses, even airplanes and ships
