Abstract

The invention relates to a car flood-proof safety airbag device, which is installed on a chassis of the car. The car flood-proof safety airbag device comprises independent buoyancy airbags, independent gas generators, an inflating control valve, an automatic sensing switch, a manual switch and the like. The buoyancy airbags are grouped and installed around the chassis of the car. When a flood happens, the car flood-proof safety airbag device can automatically or manually started up, the gas generators generate high-pressure gas to rapid inflate the buoyancy airbags, the inflated buoyancy airbags break through shells and are expanded and raised towards the external side of the car under the direction binding effect of the shells, the car is lifted up due to buoyancy and float in water, and after certain pressure is reached, the inflating control valve automatically decreases inflating speed or stops inflating and keeps the buoyancy of the buoyancy airbags for rescue. Moreover, an anchor assembly can be additionally installed at the bottom of the car to stabilize a car body when the car floats, so as to further improve safety performance.

Description

Automobile is prevented the water logging air bag device

Affiliated technical field

The present invention relates to the anti-water logging air bag device of a kind of automobile, can prevent effectively that automobile is harmful by water enchroachment (invasion) when the burst water damage, passenger and automobile property safety in the protection car.

Technical background

In recent years, along with global warming, the extreme climate disaster takes place frequently, often take place in each big city roadlice on the way, in the accident that Di Ku is inundated with flood, bring about great losses to people's lives and properties.

Summary of the invention

The object of the invention just provides and a kind ofly can prevent effectively that automobile from not had by water logging, and rescue provides the technology of main chance to lives and properties.

Technical solution of the present invention is: the anti-water logging air bag device of automobile is installed on the roadlice chassis; This device is by independent floatage air bag, separate gas producer, ventilating control valve; Compositions such as automatic inductive switch, hand switch; A plurality of independent floatage air bags divide into groups to be installed in around the car chassis, also can be made up of floatage air bag assembly, inflator assembly, automatic inductive switch, hand switch etc., and a plurality of floatage air bag assemblies divide into groups to be installed in around the car chassis.Independent floatage air bag is by base, and housing, the floatage air bag that is folded in the housing are formed, and are that high-pressure air pipe is connected with the separate gas producer between a plurality of independent floatage air bags; The floatage air bag assembly is made up of base, housing, floatage air bag and the inflator assembly in the housing and the ventilating control valve that are folded in the housing, is to be electrically connected between a plurality of floatage air bag assemblies, and the anti-automatic inductive switch of water logging air bag device of automobile is established hand switch in addition; When water damage takes place when; The anti-water logging air bag device of automobile can be responded to automatically or be manually opened, and gas generator produces high pressure gas, inflates for floatage air bag quickly; Gas filed floatage air bag breaks through shell; And the direction constraint that receives shell is to the vehicle outer side protrusion that expands, and roadlice will be held up by buoyancy and swim in the water, reach certain pressure after; The ventilating control valve reduces aeration speed automatically or stops inflation, keeps the buoyancy of floatage air bag to wait for rescue.

The invention has the beneficial effects as follows: with lower cost, better simply structure, water inlet sinking in the roadlice when preventing water damage effectively is for the rescue lives and properties win a lot of valuable time.

Among the figure 1, the roadlice body, 2, the floatage air bag that expands, 3, grasp, 4, the floatage air bag assembly; 5, automatic inductive switch, 6, hand switch, 7, independent floatage air bag, 8, independent external inflator assembly; 9, floatage air bag base (assembly or independent identical), 10, the ventilating control valve, 11, inflator assembly; 12, folding floatage air bag, 13, the floatage air bag housing, 14, the roadlice chassis.

The specific embodiment one:

Like Fig. 5, Fig. 6, inflator assembly 11 is arranged on the inside of floatage air bag base 9 and floatage air bag housing 13, add that folding floatage air bag 12 and ventilating control valve 10 constitute floatage air bag assemblies 4; And according to Fig. 3, Fig. 9 all around a plurality of floatage air bag assemblies 4 are installed in around the roadlice chassis, a plurality of floatage air bag assembly 4 electric being connected in parallel, the opening direction of air bag is towards vehicle outer side; When roadlice runs into water damage; Open the ventilating control valve 10 in the built-in inflator assembly 11 of a plurality of floatage air bag assembly 4 simultaneously by the hand switch of automatic inductive switch or peripheral hardware, inflator assembly 11 produces high pressure gas and inflates for folding floatage air bag 12 more quickly, and floatage air bag housing 13 is directed and pops; The floatage air bag 2 that expands expands to roadlice outside protrusion under the constraint of airbag housing 13; The buoyancy of the floatage air bag that roadlice is inflated holds up, the floatage air bag 2 of expansion reach certain pressure the time, ventilating control valve 10 apertures reduce until closing; If floatage air bag 2 has slight gas leakage; Then ventilating control valve 10 self-openings inflation, the floatage air bag 2 of expansion keep-up pressure and make roadlice swim in that the long period waits for rescue on the water surface, can also grasp assembly 3 be installed in the bottom of roadlice; When roadlice is floating, stablize car body, further improve safety performance.

The specific embodiment two:

Like Fig. 7, Fig. 8, floatage air bag base 9, floatage air bag housing 13 inside add that folding floatage air bag 12 constitutes independent floatage air bag 7, and gas generator 11 adds that ventilating control valve 10 constitutes external separate gas producer assembly 8; And according to figure; 4, Fig. 9 (installation site of independent floatage air bag 7 is identical with embodiment one) all around is installed in a plurality of independent floatage air bag assemblies 7 around the roadlice chassis, and a plurality of independent floatage air bag assembly 7 usefulness high-pressure air pipes parallel connections are connected with separate gas producer assembly 8, and the opening direction of air bag is towards vehicle outer side; When roadlice runs into water damage; Open the ventilating control valve 10 in the external separate gas producer assembly 8 by the hand switch of automatic inductive switch or peripheral hardware, external separate gas producer assembly 8 produces high pressure gas and inflates for folding floatage air bag 12 more quickly, and the floatage air bag housing is directed and pops; The floatage air bag 2 that expands expands to roadlice outside protrusion under the constraint of airbag housing 13; The buoyancy of the floatage air bag 2 that roadlice is inflated holds up, the floatage air bag 2 of expansion reach certain pressure the time, ventilating control valve 10 apertures reduce until closing; If floatage air bag 2 has slight gas leakage; Ventilating control valve 10 self-openings inflations, the floatage air bag 2 of expansion keep-up pressure and make roadlice swim in the water surface to wait for rescue on the long period, can also grasp assembly 3 be installed in the bottom of roadlice; When roadlice is floating, stablize car body, further improve safety performance.
