Abstract
The utility model relates to a gas generator, in particular to a non-azide type gas generator of an air bag restraint system on a driver seat, which solves the problems that the existing gas generator has large volume, complicated structure, complex assembling process, and high production cost, and does not conform to environmental protection requirements. The gas generator comprises an upper shell and a lower shell, wherein the side wall of the lower shell is provided with vents; the shell is internally provided with a gas generating powder chamber containing non-azide gas generant and a sealing cover; the gas generating powder chamber is internally provided with an igniting power box; an ignition element assembly is installed above the internal part of the igniting power box; the top part of the ignition element assembly extends into the sealing cover and is sheathed with a short circuit sleeve; an annular filtering net is arranged between the shell and the gas generating power chamber; and the outer walls of the gas generating powder chamber and the igniting power box are distributed with gas generating holes and igniting holes. The gas generator has simple structure, small volume, simple assembling process, and low production cost, simultaneously adopts non-toxic or low-toxicity non-azide gas gernerant as gas generating medicament, leads the links such as manufacturing, recycling and the like of the air bag restraint system to conform to the requirements of environmental protection, and is suitable for mass production.
Description
Technical field
The utility model relates to a kind of gas generator, is specially a kind of non-nitrine type master operator's saddle air-cushion inflator that is used for automobile.
Background technology
Safety air bag is a noticeable hightech device on the Modern Car, and the car of air bag device has been installed, in case strong collision has taken place car body, safety air bag will launch rapidly, is used for protecting chaufeur and passenger's safety.In recent years; along with the continuous development of safety airbag technique and the keen competition in market; the direction of its development is small-sized lightness; assembly technology requires simple and low-cost; simultaneously; the gas generator of air bag system mainly adopts sodium azide/oxidizer as gas generant at present; it is low that this propellant has combustion temperature; gaseous product is the advantage of non-poisonous nitrogen; but sodium azide is a kind of material of severe toxicity; give the manufacturing of safety air bag; storage and removal process have all been brought very big potential safety hazard; therefore; adopt the new gas generation technique; develop non-azide gas generant nontoxic or that toxicity is little; make the manufacturing of safety air bag; links such as recovery all meet requirement on environmental protection, also will be one of safety airbag technique future development trend.The gas generator of chief aviation pilot's air bag system and air bag are to leave in the bearing circle liner; and can not decompose; firing unit, gas generant etc. are arranged in the gas generator; development and little, the lightweight New Type of Gas Generator of employing volume; the miniaturization and the lightness that will help airbag module, and then realization is to passenger's omnibearing protection.But the gas generator of existing most of main operator's saddle safety air bags all exists, and volume is big, complex structure, assembly technology complexity, causes the productive costs problem of higher then, is unfavorable for the popularization in market.
Summary of the invention
The utility model is in order to solve existing main operator's saddle air-cushion inflator because unreasonable structure, have that volume is big, complex structure, assembly technology complexity, productive costs is higher and gases used propellant has severe toxicity, do not meet the problem of environmental demands, a kind of non-nitrine type master operator's saddle air-cushion inflator is provided.
The utility model is to adopt following technical scheme to realize: non-nitrine type master operator's saddle air-cushion inflator, comprise the housing that constitutes by upper shell and lower house, the lower house sidewall has air extractor vent, the upper shell top is provided with mounting hole, be provided with in the housing and the aerogenesis coyote hole of non-azide gas generant be housed and set up above it seal cover cap, the indoor middle part of gas generant composition in accordance is provided with the igniter cartridge that igniter is housed, igniter is equipped with in the top in the igniter cartridge, the igniter top is stretched in the seal cover cap and is with the short circuit cover, be provided with the ring-type filter screen between housing and the aerogenesis coyote hole, aerogenesis coyote hole and igniter cartridge outer wall are intervally distributed with aerogenesis hole and ignition hole.The utility model constitutes air bag system with sensor, microprocessor and air bag in actual applications.
Be provided with spoiler in the described ring-type filter screen, can play buffer action, reduce impact air bag to a large amount of high pressure gas of the indoor generation of gas generant composition in accordance.
Compared with prior art; the utility model is assembled by upper shell, lower house, aerogenesis coyote hole and several parts such as seal cover cap, igniter cartridge thereof; simple in structure, volume is little; and assembly technology is simple; productive costs is lower, adopt nontoxic simultaneously or non-azide gas generant that toxicity is little as gas producing medicinal, make the link such as manufacturing, recovery of safety air bag all meet requirement on environmental protection; be fit to produce in enormous quantities, have certain market popularization value and value of service.

The specific embodiment
Non-nitrine type master operator's saddle air-cushion inflator, as shown in Figure 1, comprise the housing that constitutes by upper shell 1 and lower house 2, on, lower house can adopt friction welding to connect, lower house 2 sidewalls have air extractor vent 3, upper shell 1 top is provided with mounting hole 4, place in the housing and the aerogenesis coyote hole 5 of non-azide gas generant is housed and sets up above it seal cover cap 6, the igniter cartridge 7 that igniter is housed is placed at the middle part in the aerogenesis coyote hole 5, igniter 8 is equipped with in the top in the igniter cartridge 7, be the electronics pyrotechnic, igniter 8 tops are stretched in the seal cover cap 6 and are with short circuit cover 9, between housing and the aerogenesis coyote hole 5 ring-type filter screen 10 is housed, ring-type filter screen 10 internal fixation have spoiler 13, and aerogenesis coyote hole 5 and igniter cartridge 7 outer walls are intervally distributed with aerogenesis hole 11 and ignition hole 12.
When running into emergency episode; igniter is according to the indicator signal energising and the superquick action of sensor and microprocessor; and the igniter in the igniter cartridge lighted; it is indoor that the high-temperature gas that generates enters gas generant composition in accordance by the aerogenesis hole; non-azide gas generant and strong chemical reaction takes place simultaneously ignites; produce a large amount of innocuous gas in short time at the utmost point; gas enters filtering net to remove the impurity of wherein carrying secretly then; also can play simultaneously heat exchange action to reduce the temperature that generates gas; and the buffering by spoiler; can reduce the detonation velocity of high pressure gas; gas after the cooling is gone out through the air extractor vent of housing outer wall immediately; the airbag aeration that will link to each other with gas generator is to full state; and make air bag wash the lid on the bearing circle open and launch fully by strong wallop; impact can be evenly distributed in head and chest; prevent that the fragile human body and vehicle body from producing direct impact; significantly reduce injured possibility; if be used with safety strap, the safety guard-safeguard effect that performance is maximum.
