Description
Technical field:
The utility model relates to a kind of hybrid gas generator, relates in particular to a kind of automobile side air bag, the hybrid gas generator of gas curtain air bag.
Background technology:
The frequent generation of traffic accident has caused huge injury for people's body and mind, being used of safety strap and side air bag, gas curtain air bag reduced injury rate greatly, present automobile side air bag, gas curtain air bag gas generator complex structure, volume is big, the cost height, and the gas generating agent toxicity that adopts is bigger, the gas of objectionable impuritiess such as igniting back generation sulfur-bearing, be 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, so just increase cost, complex manufacturing at airbag.
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, no residue, the automobile side air bag that cost is low, the hybrid gas generator of gas curtain air bag.
The purpose of this utility model can reach by following measure: a kind of automobile side air bag, the hybrid gas generator of gas curtain air bag, it has housing 5, it is characterized in that being provided with in the housing 5 compression gas chamber 6 and medicament chamber 8, pass through dividing plate 7 isolating seals between compression gas chamber 6 and the medicament chamber 8, medicament chamber's 8 point of connection fire tubes 9, ignition tube 9 is connected with housing 5 by rear base 10, the front portion of housing 5 is provided with air extractor duct 11, air extractor duct 11 communicates with compression gas chamber 6, air extractor duct 11 places are provided with seals diaphragm 4, base 2 before housing 5 connects, preceding base 2 is provided with air gate 3.
In order further to realize the purpose of this utility model, described dividing plate 7 is curved.
In order further to realize the purpose of this utility model, described dividing plate 7 is a sheetmetal.
In order further to realize the purpose of this utility model, be provided with filtering net 12 in the described preceding base 2.
In order further to realize the purpose of this utility model, described rear base 10 and housing 5 welding.
The utility model can produce following good effect compared with the prior art: because ignition tube of the present utility model passes through electronic striking, enter airbag mix generation cryogenic high pressure miscellaneous gas after the generation high temperature nitrogen again with pressure gas after, 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 automobile side air bag, the hybrid gas generator of gas curtain air bag (referring to accompanying drawing), it has housing 5, be provided with two chambers in the housing 5, one is compression gas chamber 6, inside is full of the pressure gas argon gas, one is medicament chamber 8, inside is provided with gas generating agent, pass through curved dividing plate 7 isolating seals between compression gas chamber 6 and the medicament chamber 8, dividing plate 7 is made by sheetmetal, medicament chamber 8 connects electronic ignition pipe 9, and electronic ignition pipe 9 is connected with housing 5 by rear base 10, and rear base 10 passes through the special process weld together with housing 5.The front portion of housing 5 is provided with air extractor duct 11, and air extractor duct 11 communicates with compression gas chamber 6, and air extractor duct 11 is sealed mouth by sealing diaphragm 4, and base 2 before the front end of housing 5 connects is provided with filtering net 12 in the preceding base 2, and preceding base 2 is provided with air gate 3.During use, ignition tube 9 is linked to each other with the control system (ECU) of automobile, by standing screw 1 preceding base 2 is connected with car body, when automobile bumps, (ECU) sends the igniting electric impulse signal to ignition tube 9 by control system, ignition tube is lighted rapidly, the gas generant composition in accordance in the medicament chamber 8 of under the effect of ignition tube 9, igniting, the high temperature nitrogen that gas generant composition in accordance produces expands rapidly, makes dividing plate 7 explosions, and high temperature nitrogen and compression gas chamber 6 interior argon gas mix, form the cryogenic high pressure miscellaneous gas, the air pressure of housing inner chamber is risen rapidly, make and seal diaphragm 4 and break, miscellaneous gas is by air extractor duct 11, filtering net 12, air gate 3 enters airbag.
