Abstract
The utility model offers a vehicle safety air bag, including a pressure sensor, a gas generator and an air bag. Wherein, the pressure sensor is arranged at the inner side of a bumper; the fan-out of the gas generator is connected hermetically with the air bag. The utility model is characterized in that as follows: the pressure sensor adopts piezoelectric ceramics materials; the gas generator includes a gunpowder barrel filled with gunpowder and an electric spark solicitation device; the electric spark solicitation device arranged in the gunpowder barrel is connected with the electrode of the piezoelectric ceramics by means of lead; the air bag is arranged hermetically at the whiffing end of the gunpowder barrel. The utility model adopts the piezoelectric ceramics to induce the degree of collision of the vehicle, and makes use of the electric spark solicitation device to make the gunpowder to deflagrate instantly, and then produces a high pressure gas timely to fill into the air bag so as to protect the driver. The utility model overcomes the defects brought about by the primary air bags which adopt an electronic sensor system and an air bottle type air bag that the inflation time is too long; the cost is high; combined with the installation and the repair are inconvenient. The utility model has the advantages of that the structure is simple with a low cost; in addition, the installation and the repair are convenient; at the same time, the air bag can be inflated quickly and evenly, and thus be convenient for promotion and popularization.
Description
Affiliated technical field
The utility model provides a kind of safe automobile air bag, belongs to prevent that the occupant from avoiding the fender guard technical field of colliding and injuring.
Background technology
At present existing many high-grade cars have been installed safety air bag, with regard to its technical scheme, bigger gas cylinder inflation mechanism of complicated electronic sensor system, heaviness and volume and the air bags of adopting are formed more, the inflationtime of air bag can not be guaranteed the anticipation time of airbag-releasing, and be equipped with installation, maintenance and change difficulty, the cost height is unfavorable for popularizing and promoting.
The utility model content
The purpose of this utility model provides a kind ofly can overcome above-mentioned defective, simple in structure, installation and maintenance are convenient, cost is low, the safe automobile air bag of excellent working performance.Its technical scheme is:
Comprise pressure sensor, gas generator and air bag, wherein pressure sensor is installed in the inboard of car front bumper, the mouth of gas generator is connected with air sac sealing, it is characterized in that: pressure sensor adopts piezoceramic, gas generator comprises powder flask and the electro spark initiating mechanism that fills gunpowder, wherein the electro spark initiating mechanism is arranged in the powder flask, connects the electrode tip of piezoceramic through lead, and air sac sealing is arranged on the jet end of powder flask.
Described safe automobile air bag, pressure sensor are installed on the insulation fixed mount, set up the inboard that distortion baffle plate bar is fixed on the car front bumper, the place ahead that is positioned at pressure sensor, and the two ends of insulation fixed mount connect distortion baffle plate bar through spring respectively.
Described safe automobile air bag, set up and have the reaction plate that runs through cavity, powder flask is installed in the cavity, its front end is captiveed joint with reaction plate through solid ignition Safety nut, its jet end is captiveed joint with reaction plate through the disappointing nut of hollow dividing potential drop, the sidewall of the disappointing nut of dividing potential drop is provided with exhausr port, and reaction plate is provided with the groove of placing air bag around the jet end of powder flask, and air bag opening is around the sidewall sealing and fixing of powder flask by clip and groove.
Described safe automobile air bag is set up master cock, is serially connected in the electric power loop of pressure sensor.
Its principle of work is: utilize piezoceramic induction collision alarm; piezoceramic is by the high pressure more than the bruising generation 2000V when automobile is hit distortion; and to connected pyrophoric body discharge; make the gunpowder of electro spark initiating mechanism in moment initiation container; gunpowder detonation generation high pressure gas are opened immediately and are full of air bag, and driver and crew are protected.
The utility model compared with prior art, and is simple in structure, and installation and maintenance are convenient, and cost is low, and the airbag aeration time is short, and safety control efficient height is convenient to popularize.
