Abstract

The invention discloses an anti-scalding safety gasbag. The anti-scalding safety gasbag comprises a cylinder body. A piston capable of moving front and back in the cylinder body is arranged in the cylinder body, and the cylinder body is divided into a front cavity and a rear cavity by the piston. The anti-scalding safety gasbag further comprises a control circuit with a primer. The primer on the control circuit stretches into the front cavity, a gas generating agent capable of being ignited by the primer is placed in the front cavity, and a cooling medium is placed in the rear cavity. The front cavity is connected with a gasbag body through a connecting pipeline, a closed interlayer bag is arranged on the side, facing the human body, of the gasbag body, and the rear cavity is connected with the interior of the interlayer bag through a connecting pipeline. According to the structure, when cars collide and collision force exceeds a set value, current is connected and flows through an electrode to ignite the primer and the gas generating agent, gas generated by explosion completely enters the gasbag body, meanwhile, reacting force generated by explosion pushes the piston to squeeze a sealed package of the cooling medium open so that the cooling medium can be pressed into the interlayer gasbag under the action of the piston, and then it is prevented that the human body is scalded by high-temperature gas.

Description

Burn-proof safety air bag

 

Technical field

The present invention relates to a kind of safety air bag, specifically a kind of burn-proof safety air bag.

Background technology

Conventional security air bag generally comprises the cylinder body that gunpowder is housed and the air bag be connected with cylinder body; connection control circuit on cylinder body; when there being shock signal; control circuit controls igniting; gunpowder explodes rapidly generation expanding gas, and the high-temperature expansion gas caused by exploding is filled with air bag and directly and human contact, but the gas temperature produced due to blast is higher; make the utricule of air bag surface have very high temperature, thus make it be scalded by human body while generation protective effect.

Summary of the invention

It is simple, safe and reliable that the technical problem to be solved in the present invention is to provide a kind of structure, can avoid the burn-proof safety air bag of scalding human body completely.

In order to solve the problems of the technologies described above, burn-proof safety air bag of the present invention, comprise cylinder body, the piston that can move forward and backward in cylinder body is provided with in cylinder body, cylinder body is separated into front cavity and rear chamber by piston, also comprise the control circuit with primer, primer on control circuit extend in front cavity, the gas generant can lighted by primer is placed in front cavity, cooling media is placed in rear chamber, front cavity connects air bag utricule by connecting line, air bag utricule is provided with closed interlayer capsule towards the side of human body, rear chamber is by connecting line connection interlayer capsule.

Described gas generant is sodium azide particle.

Described cooling media is refrigerant fluid.

Described cooling media is sealed in cooling media sealed package.

After adopting above-mentioned structure, when automobile collides, impact exceedes setting value, current turns ON flows through electrode lights primer and gas generant, gas generant blast high-temperature expansion, and the gas that blast produces all enters in air bag utricule, simultaneously due to the effect of piston, the antagonistic force that blast produces promotes piston and racks cooling media sealed package, is pressed into by cooling media in interlayer gas bag, prevents high-temperature gas to scald human body.

Accompanying drawing explanation

Fig. 1 is the structural representation of burn-proof safety air bag of the present invention.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, burn-proof safety air bag of the present invention is described in further detail.

As shown in the figure, burn-proof safety air bag of the present invention, comprise cylinder body 1, be provided with the piston 2 that can move forward and backward in cylinder body in cylinder body 1, cylinder body 1 is separated into front cavity 3 and rear chamber 4 by piston 2, also comprise the control circuit 6 with primer 5, primer on control circuit 6 extend in front cavity 3, places the gas generant 7 can lighted by primer, place cooling media 8 in rear chamber 4 in front cavity 3, cooling media 8 is refrigerant fluid, and cooling media is sealed in cooling media sealed package; Front cavity 3 connects air bag utricule 9 by connecting line, and air bag utricule 9 is provided with closed interlayer capsule towards the side of human body, and rear chamber 4 is by connecting line connection interlayer capsule, and said gas generant 7 is sodium azide particle.

Its principle of work is as follows:

When automobile collides, impact exceedes setting value, current turns ON flows through electrode lights primer and gas generant, gas generant blast high-temperature expansion, the gas that blast produces all enters in air bag utricule, and simultaneously due to the effect of piston, the antagonistic force that blast produces promotes piston and racks cooling media sealed package, cooling media is pressed in interlayer gas bag, prevents high-temperature gas to scald human body.
