Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Shown in Fig. 1～11, a kind of electric gas-filled air bag, comprise air bag 1 and the inflator that is connected with air bag 1 inlet, inflator is by circuit board 3, direct current generator 4, eccentric shaft 5, link 6, inflation leather cup 7, has suction port 12, the three-way body 10 of air outlet 14 and leakage port 13, and housing 8 compositions with air cavity 9, these air cavity 9 one ends communicate with the inlet of air bag 1, and the other end communicates with the air outlet 14 of three-way body 10, direct current generator 4 is installed on the housing 8, eccentric shaft 5 is fixedlyed connected with the output shaft of direct current generator 4, and inflation leather cup 7 is sleeved on the three-way body 10 and by link 6 and is connected with eccentric shaft 5, and the suction port 12 of three-way body 10 and air outlet 14 are provided with by unidirectional valve 11.Direct current generator 4 is a DC micromotor, and voltage rating is 12～36V, power 1.6～30W, 4000～10000 rev/mins of motor speeds.Inflation leather cup 7 adopts endurance, ageing-resistant rubber to make.
Shown in Fig. 1,3, also install on the housing 8 by solenoid valve 2, the valve 2-1 of this solenoid valve 2 communicates with the air cavity 9 of housing 8, and the upper end of solenoid valve 2 has the relief opening that communicates with valve 2-1.When the gas in the air bag is too sufficient, can open the valve 2-1 of solenoid valve 2, unnecessary gas is discharged from the relief opening of solenoid valve 2 upper ends, easy to operate.Also can directly on air bag 1, outlet valve be set, but inconvenient operation is difficult to control air displacement.
As shown in figure 12, the circuit on the circuit board 3 is made up of capacitor C, inductance L, diode D and peripheral circuit thereof, and capacitor C is in parallel with direct current generator 4, and diode D is in parallel with solenoid valve 2.The power supply of this circuit can adopt small battery or dryelement cell, also can directly utilize the DC electrical source of automobile self, and is easy to use.
The unidirectional valve 11 that the utility model uses can adopt rubbery membrana dermalis to make low cost of manufacture.
Working principle of the present utility model is as follows: during inflation, start direct current generator 4, direct current generator 4 runnings, its output shaft drives eccentric shaft 5 rotations, eccentric shaft 5 drives inflation leather cup 7 by link 6 and back and forth twists, the one-way cock 11 of the suction port 12 of three-way body 10 is opened, from the suction port 12 air-breathing three-way bodies 10 that enter, the one-way cock 11 of air outlet 14 is opened then, gas in the three-way body 10 enters the air cavity 9 of housing 8 by air outlet 14, and the gas in the air cavity 9 enters air bag by the inlet of air bag 1, the reciprocal twisting of inflation leather cup 7, can constantly in air bag 1, inflate, till abundance.Gas unnecessary in the three-way body 10 can be discharged by the leakage port of three-way body 10.When the gas in the sensation air bag 1 is too sufficient, can open the valve 2-1 of solenoid valve 2, make gas unnecessary in the air bag 1 from discharging from the relief opening of solenoid valve 2 upper ends through valve 2-1.
