Technical field:
The utility model relates to a kind of hybrid gas generator, relates in particular to a kind of safe automobile air bag master and drives hybrid gas generator, is used to be furnished with the self-propelled vehicle inflatable safety system of air bag.
Background technology:
The frequent generation of traffic accident has caused huge injury for people's body and mind; for better protection being provided for chaufeur when traffic accident takes place; reduce the generation of personal casualty incident; safety airbag technique more and more is applied on the automobile; so that when having an accident, utilize air bag to alleviate vibrations or absorption impact energy; make air bag finish inflation in the moment that has an accident; need to adopt gas generator, present gas generator complex structure, volume is big; the cost height; and the gas generating agent toxicity that adopts is bigger, and the gas of objectionable impuritiess such as igniting back generation sulfur-bearing is unfavorable for environmental protection; and the temperature that the igniting back produces is higher; easily the people is scalded, prevent to scald the people, just need add anti-high-temperature coating at airbag; so just increased cost, complex manufacturing.
The content of utility model:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of simple and practical, and volume is little, clean environment firendly, and no residue, the safe automobile air bag master that cost is low drives hybrid gas generator.
The purpose of this utility model can reach by following measure: a kind of safe automobile air bag master drives hybrid gas generator, it has shell 2, shell 2 is provided with deflation hole 1, it is characterized in that connecting in the shell 2 plenum chamber housing 9, be provided with main plenum chamber 7 in the plenum chamber housing 9, secondary plenum chamber 3, medicament chamber 10, main plenum chamber 7 is by gas port 5 auxiliary connection plenum chambers 3, seal by medicament chamber's seal membrane 4 between secondary plenum chamber 3 and the medicament chamber 10, main plenum chamber 7 is provided with seal vents 13, seal vents 13 places are provided with main plenum chamber seal membrane 6, plenum chamber housing 9 connects squib 12, and squib 12 places in the medicament chamber 10.
In order further to realize the purpose of this utility model, described deflation hole 1 is the annular row pore.
In order further to realize the purpose of this utility model, described main plenum chamber 7 is annular main plenum chamber.
In order further to realize the purpose of this utility model, described gas port 5 rectangular distributions.
In order further to realize the purpose of this utility model, described seal vents 13 is arranged with two.
In order further to realize the purpose of this utility model, described shell 2 is provided with fixed orifice 8.
In order further to realize the purpose of this utility model, described main plenum chamber seal membrane 6 is the convex seal membrane.
In order further to realize the purpose of this utility model, described medicament chamber seal membrane 4 is the matrix seal membrane.
The utility model can produce following good effect compared with the prior art: owing to be filled with the environmental protection gases such as argon gas that are lower than the seal membrane bursting pressure in the plenum chamber of the present utility model, squib passes through electronic ignition, light the gas generant composition in accordance in the medicament chamber, gas generant composition in accordance is burnt rapidly and is produced the seal membrane explosion that the high pressure gas shock wave makes medicament chamber, environmental protection gases such as argon gas in high pressure gas and the plenum chamber enter airbag after mixing generation cryogenic high pressure miscellaneous gas, therefore not only environmental protection, and it is simple in structure, volume is little, cost is low, and the miscellaneous gas temperature of generation is low, and airbag need not to add anti-high-temperature coating outward, and clean environment firendly, no residue.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing preferred forms of the present utility model is elaborated:
Embodiment: a kind of safe automobile air bag master drives hybrid gas generator (referring to accompanying drawing), it has shell 2, shell 2 is provided with annular row pore 1, fixed orifice 8, connect plenum chamber housing 9 in the shell 2, be provided with annular main plenum chamber 7 in the plenum chamber housing 9, secondary plenum chamber 3, the medicament chamber 10 of secondary plenum chamber 3 belows, be filled with the inertia environmental protection gases such as argon gas that are lower than the seal membrane bursting pressure in main plenum chamber 7 and the secondary plenum chamber 3, main plenum chamber 7 is by well-distributed gas port 5 auxiliary connection plenum chambers 3, isolate by matrix medicament chamber seal membrane 4 between secondary plenum chamber 3 and the medicament chamber 10, main plenum chamber 7 is provided with two seal vents 13 of symmetry, each seal vents 13 place is provided with convex master plenum chamber seal membrane 6, main plenum chamber 7 and deflation hole 1 are isolated, plenum chamber housing 9 connects squib firm banking 11, squib firm banking 11 is squib 12 fixedly, squib 12 places in the medicament chamber 10, and is packaged in the medicament chamber 10 with gas generant composition in accordance.During use, squib 12 is linked to each other with the control system (ECU) of automobile, by fixed orifice 8 shell 2 is connected with car body, when automobile bumps, (ECU) sends the igniting electric impulse signal to squib 12 by control system, squib is lighted rapidly, the gas generant composition in accordance in the medicament chamber 10 of under the effect of squib 12, igniting, the high temperature nitrogen that gas generant composition in accordance produces expands rapidly, make 4 explosions of medicament chamber's seal membrane, high temperature nitrogen is mixed with argon gas in the secondary plenum chamber 3, form the cryogenic high pressure miscellaneous gas and enter main plenum chamber 7 by gas port 5 rapidly, the gas of main plenum chamber 7 is expanded, and the gaseous tension after the expansion makes main plenum chamber seal membrane 6 rapid explosions, and gas enters air bag by the deflation hole on the shell 21.
