Description
Technical field
The utility model relates to a kind of gas generator, is specially a kind of front passenger's seat air-cushion inflator that is used for automobile.
Background technology
Safety air bag is a noticeable hightech device on the Modern Car, the car bearing circle of air bag device has been installed, usual do not have any difference with common bearing circle, in case but strong collision has taken place in the car front end, safety air bag will come out moment " spring " in bearing circle, pad prevents that driver's head and chest from striking on the hard thing such as bearing circle or instrument carrier panel between bearing circle and driver.The rudimentary car of senior middle school of various countries' production at present, great majority all are equipped with safety air bag, some car has been listed safety air bag in must piece installing, but has equipped the front passenger's seat safety air bag except the senior car of only a few at present, and most of vehicle has also just been installed main operator's saddle safety air bag.At home, the customer is also more and more higher to the requirement of vehicle safety performance, but main operator's saddle safety air bag also just has been installed.In fact, the safety air bag that the passenger that some luxury cars are installed uses is similar to the safety air bag that the motorist uses, just the volume of air bag wants big, required gas is also more, but the gas generator that plays a crucial role in this safety air bag is because its structural defective exists gas yield deficiency, aerogenesis to wait shortcoming slowly, thereby cause air bag in time not to be filled up or to be full of, influence the safe handling effect of air bag; And its structure more complicated, cost are higher.Therefore, press for and a kind ofly can be widely used in various vehicles, simple in structure, front passenger's seat air-cushion inflator that safety performance is good.
Summary of the invention
The utility model is defective such as existing air-cushion inflator complex structure, cost are higher, poor stability and a kind of front passenger's seat air-cushion inflator is provided in order to solve.
The utility model is to adopt following technical scheme to realize: the front passenger's seat air-cushion inflator, comprise the seal casinghousing that constitutes by left plug, right plug and cylinder blanket, have air extractor vent on the housing outer wall, be with the aerogenesis medicine box that has air extractor vent on it in the housing, be provided with filtering net between inner walls and the gas generant composition in accordance outer box wall; Be with the starting mix tube that has air extractor vent on it in the aerogenesis medicine box, be full of gas producing medicinal between aerogenesis medicine box inwall and the starting mix drum outer wall, be full of the starting mix agent in the starting mix tube, starting mix drum outer wall and be positioned at the air extractor vent place and be provided with sealing mat, igniter is equipped with in starting mix tube one termination, and the igniter top is stretched in the hole seat of left plug and is with the short circuit cover.The utility model can load gas producing medicinal according to the volume of air bag and the kind of medicament, and the utility model constitutes air bag system with sensor, microprocessor and air bag in actual applications.When running into emergency episode; igniter is according to the indicator signal energising and the instantaneous Fast Heating of sensor and microprocessor; medicament in the starting mix tube is lighted; the high-temperature gas that generates enters in the aerogenesis medicine box by air extractor vent; gas producing medicinal and strong chemical reaction takes place simultaneously ignites; produce a large amount of innocuous gas in short time and enter filtering net to remove the impurity of carrying secretly in the gas at the utmost point by air extractor vent; also can play simultaneously heat exchange action to reduce the temperature that generates gas; the airbag aeration that gas after lowering the temperature immediately will link to each other with gas generator is to full state; and air bag is washed open by strong wallop, effectively protected passenger's head and chest.
Gas generant composition in accordance outer box wall described in the utility model is provided with barrier film, and described barrier film can be the very thin aluminum foil tape of one deck, can prevent that gas producing medicinal from being fallen in the filtering net by air extractor vent, can prevent that also medicament from making moist simultaneously.
Aerogenesis medicine box end described in the utility model is provided with clamping pad, interior plug and packing seal successively, in order to gas producing medicinal and real, the sealing of starting mix agent heap, makes the gas of reaction generation have strong wallop, can prevent that also medicament from making moist simultaneously.
The fitting surface of igniter described in the utility model is fixed by sealing rubber and left plug.
Compared with prior art, the utility model and sensor, microprocessor, air bag constitute air bag system, can be loaded on front passenger's seat the place ahead, prevent that effectively fragile passenger's human body and vehicle body from producing direct impact, significantly reduce injured possibility, not only simple in structure, cost is lower, and aerogenesis is fast and stablize, and can be widely used in the car of high, normal, basic class.
