Abstract
The utility model discloses a mixed gas producer for an automobile safety airbag, which solves the problems that structures and assembling processes of the prior art are complicated, which results in the increase of the cost. The mixed gas producer for an automobile safety airbag comprises a high pressure cylinder, wherein one end of the high pressure cylinder is provided with a gas producing device and the other end is provided with a bottle mouth which is frapped inside. The inner wall of the bottle mouth is provided with an arc-shaped bursting piece, and a filtering net is arranged between the bottle mouth and the bursting piece. An exhaust hole is arranged on position of the bottle mouth corresponding to the filtering net. Buffering function can be played by the buffering filtering net when gas producing medicine is assembled, and thus the gas producing medicine can not be squeezed to break when assembled. At the same time, when products are transported and stored, the gas producing can not mutually rub and swing and thus the safety of the products can be raised. After the gas producing medicine is burnt, residues can also be filtered by the buffering filtering net and thus the content of the residues in released gas is reduced. Produced hot gas and mixed gas can be filtered by the filtering net to ensure that gas which is released by the gas producer has fewer residues or no residues.
Description
Technical field
The utility model relates to a kind of gas generator, relates in particular to a kind of safe automobile air bag gas generator.
Background technology
Along with the raising of Freeway Development and automotive performance, automobile driving speed is more and more faster, and traffic is more and more crowded, and it is frequent to cause the accident, so vehicle safety is more and more important.Vehicle safety is divided into two kinds of active safety and passive securities, safe automobile air bag is one of high-tech product in the vehicle passive safety technology, its design-calculated basic thought is: after automobile bumps, before occupant and the collision of car inner member, between the two, open a gassiness air cushion rapidly, the occupant " is pounced on " on air cushion, impact and the absorption collision energy to relax, thereby reach the purpose that alleviates the occupant injury degree.Concrete action principle is: in vehicle traveling process, sensor amplification system in the gas-bag system constantly changes (or acceleration/accel) information to the electronic control unit transmission speed, electronic control unit is to these information analysis and judgement in addition, if institute's measuring acceleration, velocity variable or other variable quantities surpass predetermined value (collision case has promptly really taken place), then electronic control unit sends firing command or the igniting of sensor direct control to gas generator, the reaction of blasting after the igniting produces N2 or the pressure gas in the storage tank is discharged and is full of airbag rapidly.When the occupant contacts with airbag,, thereby reach the purpose of protecting the member by the damping absorption collision energy of airbag upper air-vent.Gas generator is the parts that produce gas, is the gas source in the safe automobile air bag.The gas generator that is used for safe automobile air bag in the world mainly contains three kinds of forms: pyrotechnic, high-pressure gas bottle formula and hybrid.The fast burn that the gas part of hybrid gas generator derives from pyrotechnic composition discharges, and another part derives from the high pressure gas of compression in advance.Hybrid gas generator described in the utility model patent is mainly used in the more safety air bags of gas flow needs such as occupant's head-on crash protection air bag.US Patent (US5589141) discloses a kind of hybrid producer of structure, comprise a gas cylinder, one end opening of this gas cylinder passes through end cap seal, other end opening tightens up inwards, be equipped with an arch rupture disk at the opening inwall, be equipped with the aerogenesis cartridge case on the described end cap, this aerogenesis cartridge case is built-in with gas generant composition in accordance, this gas generant composition in accordance compresses support by a spring to it, is full of the compound of argon gas and oxygen-containing gas in the described gas cylinder.Now by hybrid generator architecture complexity, assembly technology complexity, cost height.
The utility model content
At above-mentioned deficiency, the utility model provides a kind of safe automobile air bag simple in structure, that cost is low, safe in utilization hybrid gas generator.
For achieving the above object, the utility model is by the following technical solutions: the hybrid gas generator of a kind of safe automobile air bag, comprise a high-pressure gas bottle, described high-pressure gas bottle one end is equipped with aerogenesis apparatus, the bottleneck of the other end for tightening up inwards, described bottleneck inwall is equipped with an arch rupture disk, is equipped with filtering net between described bottleneck and the described rupture disk, described bottleneck with the cooresponding position of described filtering net on be equipped with a deflation hole.
As further improvement: described aerogenesis apparatus comprises an aerogenesis cartridge case, and described aerogenesis cartridge case is built-in with a starting mix tube, and described starting mix tube one end is equipped with electric igniter, and the other end is equipped with the buffering filtering net, and described starting mix tube is equipped with a medicine hole.
The utlity model has following technique effect: after described electric igniter receives firing command, in the 2-3 millisecond, light the starting mix in the described starting mix tube, starting mix after the burning is lighted gas generant composition in accordance by the some medicine hole on the described starting mix tube, gas generant composition in accordance is burnt rapidly and is produced high pressure gas shock wave and red-hot high pressure gas, these high pressure gas are after described buffering filtering net filters, mix with the high pressure gas in being fitted in described high-pressure gas bottle in advance, make the gaseous tension in the described high-pressure gas bottle rise after the mixing, this pressure is enough to described rupture disk is punctured, after high pressure mixed gas breaks through described rupture disk, filter by described filtering net, the miscellaneous gas after the filtration enters air bag through described deflation hole again.Described buffering filtering net can play buffer action when gas generant composition in accordance is assembled, in order to avoid when assembling squeezes gas generant composition in accordance broken; Simultaneously when storing, Product transport prevents that the phase mutual friction is rocked between the gas generant composition in accordance, has improved security of products.Described buffering filtering net can also filter the residue after the gas generant composition in accordance burning, reduces the residue content that discharges in the gas thing.Described filtering net can filter hot gas and the miscellaneous gas that produces, and has less residue or does not have residue to guarantee the gas that gas generator was discharged.The utility model is simple in structure, cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model safe automobile air bag with hybrid gas generator.
The specific embodiment
Consult accompanying drawing 1, the hybrid gas generator of the utility model safe automobile air bag, comprise a high-pressure gas bottle 7, described high-pressure gas bottle 7 one ends are equipped with aerogenesis apparatus, the bottleneck of the other end for tightening up inwards, described bottleneck inwall is equipped with an arch rupture disk 8, is equipped with filtering net 10 between described bottleneck and the described rupture disk 8, described bottleneck with described filtering net 10 cooresponding positions on be equipped with a deflation hole 9.Described aerogenesis apparatus comprises an aerogenesis cartridge case 5, described aerogenesis cartridge case 5 is built-in with a starting mix tube 4, be equipped with gas generant composition in accordance 3 between described aerogenesis cartridge case 5 and the starting mix tube 4, described starting mix tube 4 one ends are equipped with electric igniter 13, the other end is equipped with buffering filtering net 6, and described starting mix tube 4 is equipped with a medicine hole 15.Described starting mix tube is built-in with starting mix 12.1 is that end socket, 2 is rear side housing.
