Abstract

The invention relates to a novel protection method based on an air bag, relating to a vehicle. The novel protection method based on the air bag is characterized in that a safe belt can be fastened by a driver, when the vehicle is in a collision accident, and when an impact force (deceleration) is detected to be over a set value by a control system of the air bag, an electric detonator circuit in an air inflation element can be powered-on immediately by an air bag computer, ignition medium in the electric detonator circuit can be ignited, ignition powder and a gas generating agent can be ignited by flame so that a large amount of gas can be generated, the air bag can be inflated in a short time, and the air bag can be suddenly expanded so that the collision of the driver in a hard cab can be reduced. The air bag can be arranged below a steering wheel and an instrument panel, on the side surfaces of a vehicle door and a seat, behind a front seat in front of the rear passenger and the like. After the novel protection method based on the air bag, disclosed by the invention, is adopted, the damage to the driver and the passenger during the collision accident of the vehicle can be reduced; and simultaneously, the air bag is convenient for use, has low cost, and can be quickly developed and popularized.

Description

A kind of novel means of defence based on safety air bag

Technical field

The present invention relates to a kind of novel means of defence based on safety air bag, is one of vehicle passive safety property important measures.

Background technology

Along with the raising of Freeway Development and automotive performance, the moving velocity of automobile is more and more faster, and because the increasing sharply of car owning amount, traffic is more and more crowded, makes accident more frequent, so that the safety of automobile just becomes is particularly important.In the time of can reducing automobile greatly and crash as the air bag system of vehicle passive safety property important measures to driver and crew's injury.Simultaneously, easy to use, cost is not high, will be developed rapidly and popularize.

Summary of the invention

The object of the invention is exactly in order to protect driver and crew's safety, a kind of novel means of defence based on safety air bag to be provided.

The object of the invention is realized through following technical scheme:

A kind of novel means of defence based on safety air bag; Wherein: driver and crew fasten one's safety belt, when automobile when crashing, when control system of safety air bag detects impulsive force (deceleration/decel) and surpasses setting value; Squib circuit in the safety air bag computer demand working inflation element; Light the ignition in the squib, flame point of ignition fire powder and gas generant produce a large amount of gases; With airbag aeration, air bag is sharply expanded to reduce the collision of driver and crew in hard compartment at short notice.

Above-mentioned a kind of novel means of defence based on safety air bag, wherein: the impulsive force intensity limit value that bumps is that control system is predefined.

Further, a kind of novel means of defence based on safety air bag, wherein: described control system of safety air bag is made up of crash sensor, safety air bag computer, SRS indicator lamp and air bag component four parts.

Further; A kind of novel means of defence based on safety air bag; Wherein: crash sensor detects the strength signal of auto against, and signal is imported the safety air bag computer, and the safety air bag computer judges that according to the signal of crash sensor whether igniting the inflation element makes airbag aeration.

Further, a kind of novel means of defence based on safety air bag, wherein: when control system of safety air bag detects impulsive force above preset value, connect the squib circuit in the inflation element at once, light the ignition in the squib.

Further, a kind of novel means of defence based on safety air bag, wherein: flame point of ignition fire powder, and gas generant produce a large amount of gases rapidly.

Further, a kind of novel means of defence based on safety air bag, wherein: the gas of generation is nitrogen, avirulence is harmless.

Further, a kind of novel means of defence based on safety air bag, wherein: when human body collides on the air bag,, absorb the power that collision produces between human body and the air bag rapidly, thereby play buffer action by the exhaust throttle effect of air bag back side deflation hole.

Further; A kind of novel means of defence based on safety air bag; Wherein: on each seat belt checking system is installed, the control system of safety air bag that must fasten one's safety belt just keeps "on" position, and cooresponding air bag is just understood smooth opening when crashing.

One go on foot ground again, a kind of novel means of defence based on safety air bag, wherein: the control system of safety air bag that must fasten one's safety belt just keeps "on" position, has avoided the unnecessary waste in unmanned seat.

Substantive distinguishing features of the present invention and obvious improvement are embodied in: after adopting this method; Air bag only can be detonated in the place that the passenger is arranged and need; Promptly reduced the waste (fuel in the safety air bag is a kind of relatively costly chemical fuel) of resource itself; Also alleviate the degree of suffered injury when crashing, also supervised some occupants when driving, consciously to use of seat belts simultaneously.

The specific embodiment

A kind of novel means of defence based on safety air bag is one of vehicle passive safety property important measures, and its special feature is: fasten seat belts after at first driver and crew get on the bus; Be two interfaces of safety strap when being inserted in together, connected the control system of safety air bag this moment, when automobile bumps; There is the local sensor of passenger to start working here, collision impact force intensity signal is transferred to the air bag computer, and compares with its default value; If more than or equal to this default value, the safety air bag circuit of respective sensor is connected, and promptly connects the squib circuit in the inflation element at once; Light the ignition in the squib, flame point of ignition fire powder and gas generant produce a large amount of gases; Make airbag aeration rapidly, driver and crew's head and chest are pressed on the gassiness air bag, buffering is to driver and crew's impact; Reduced the actual bodily harm to driver and crew, the unnecessary wasting of resources then because safety strap is not fastened air bag and do not opened, and then has been avoided in unmanned seat.

Safety air bag can be evenly distributed in head and chest with impact, prevents that fragile passenger's human body and vehicle body from producing direct impact, significantly reduces injured possibility.In addition, the volume during the air bag outburst approximately has only 130 decibels, in the endurable scope of human body.78% gas is nitrogen in the air bag, and ten minutes is stable and do not contain toxicity, and harmless, the powder of taking out of when producing is to keep air bag not coherent lubricated powder under folded state, and is also harmless to human body.

After air bag is ignited, because the gas that produces is poured into air bag in a large number, make the increased pressure of air bag, unfavorable absorption crash energy, so, the gas discharge hole of 2 drain pressures is arranged in the back of air bag, help protecting driver and crew's safety.
