Abstract
The invention relates to an automobile airbag gas generator with a time delay inflation function. The problems that the existing opened automobile airbag is short in operating state time, high in charge mass, high in noise and high in construction cost and the driver and passengers in the automobile and road pedestrians cannot be protected during secondary collision and vehicle turning after vehicle collision are solved. The automobile airbag gas generator is characterized in that a secondary gas storage cylinder (1) and a gas generator module which consists of an anti-static ignition component, a gas diffuser (15) and a gasbag and is assembled on a gas generator shell (10) are connected inside a primary gas storage cylinder (2); when a detector (52) transmits a circuit instruction and work is conducted, high-pressure inert gases (3) in the primary gas storage cylinder (2) and the secondary gas storage cylinder (1) instantaneously and respectively rush into the automobile airbag, so that the operating time after expansion is 10 to 6,000 milliseconds, and the driver and passengers in the automobile and road pedestrians are subjected to buffer energy-absorbing protection during collision, secondary collision, vehicle turn and rear-end collision in the automobile driving process.
Description
One, technical field:
The present invention relates to a kind of high-pressure gas bottle inflatable eco-friendly car safety air bag, relate in particular to a kind of time-delay aerification function automobile safety air bag gas generator that has.
Two, background technology:
The automotive safety technology is divided into initiatively and two kinds of passive securities; Automobile bump preceding under steam or collision after the moving or passive security fender guard of the safety air bag owner that opens; The air-cushion inflator of existing automobile has weak point: the operational use time behind the airbag-releasing is the 10-120 millisecond, and inflationtime is short, and pharmaceutical quantities is big and produce a large amount of smog and pernicious gas; Noise is big; Be unfavorable for environmental protection, airbag moment surface temperature is high, scalds people's skin easily; Make that head, shoulder and the waist to chaufeur and occupant do not have the buffering energy-absorbing protective effect in the secondary collision of vehicle after collision, the vehicle rollover, and occur the quick-fried phenomenon of mistake often and do not have pedestrian impact protection and vehicle rear-end collision air bag device.Continuous increase along with automobile quantity; People more and more pay attention to the requirement of safety, " people-oriented " when choosing automobile, and the road traffic condition of China is complicated, and the pedestrian is more with vehicle mixing road; Majority belongs to a secondary hybrid cross road; Annual because of the wounded or disabled number of traffic accident injures and deaths in continuous increase, bring very big loss for people's lives and properties, a kind of to have time-delay aerification function automobile safety air bag gas generator very urgent so develop.
The objective of the invention is to overcome above-mentioned weak point: the operational use time after safe automobile air bag is opened is the 10-6000 millisecond; To improve 5880 milliseconds the operational use time, pharmaceutical quantities is few, and is large-minded; Noise is little; Airbag moment surface temperature is low, and clean environment firendly is safe in utilization; Simple in structure; Cheap, solve in secondary collision after head-on crash, side collision, collision take place automobile under steam, the vehicle rollover and the head, shoulder, waist, buttocks and the shank that reach the motor bike people to chaufeur in both sides' car, occupant, road pedestrian, by bike during vehicle rear-end collision plays the buffering energy-absorbing protective effect, at utmost to reduce personal casualty, the wounded or disabled loss that brings because of collision.
Three, invention technology contents:
The objective of the invention is to develop a kind of time-delay aerification function automobile safety air bag gas generator that has; Through the patent searching document; US Pat (US006089601A) discloses a kind of inflatable automobile occupant restraint system gas generator, comprises a high pressure vessel gas cylinder, an end opening of this high pressure vessel and base tight weld; Other end opening and end cap seal welding; Metal disk of air extractor duct end face in end cap welding is used for the gas in the airtight container, and the other end comes the roof pressure metal disk with ignition device, and the device that regulates the valves is housed in the lower end of starter gear; Be start stop afterwards cooperate synchronously with the metallic closed disk tear the interior aerification of said high pressure vessel.The weak point of inflatable automobile occupant restraint system gas generator: inflationtime is short, part is many, complex process, cost are higher, and twice automatically regulating cannot say for sure to demonstrate,prove the metallic closed disk and regulated the valves and open synchronously.
On the basis of the former patented technology of contriver " have initiatively anti-collision air bag protection function Federal bumper " (application number 200410073418.1) and " high-pressure gas bottle of car and boat active safety air bag touches air valve " (application number 200610105390.4); Improve and improve original technology; Improve gas generator working stability, safety, ageing, validity simultaneously; Solved automobile bump in preceding or collision back and secondary collision, the vehicle rollover under steam and during vehicle rear-end collision the continuity inflationtime behind the airbag-releasing reach the 10-6000 millisecond; Form the energy saving and environment friendly safety air bag of time-delay inflatable, at utmost to play the protecting energy effect that absorbs.
