Detailed Description
The invention will be further described with reference to the following figures and specific examples, but the scope of the invention is not limited thereto.
As shown in fig. 1 and 2, the two-stage automobile airbag according to the present invention includes a gas generating apparatus 1, a lower airbag 2, an upper airbag 3, an airbag main bandage 5, an airbag sub-bandage 7, and a vent controller 4; the gas generating device 1 is communicated with the lower air bag 2, and after a signal receiver in the gas generating device 1 receives an ignition signal, an ignition mechanism is triggered to initiate the reaction of a gas generating agent, so that high-temperature and high-pressure gas is generated and is quickly filled in the lower air bag 2. The lower air bag 2 is connected with the upper air bag 3 in a sewing mode, a plurality of pre-holes are formed in the sewing position between the lower air bag 2 and the upper air bag 3, a hole controller 4 is placed in each pre-hole, one end of an air bag main bandage 5 is fixed to the sewing position between the lower air bag 2 and the upper air bag 3, and the other end of the air bag main bandage 5 is fixed to the gas generating device 1; one end of the air bag auxiliary bandage 7 is fixed on the opening controller 4, the other end of the air bag auxiliary bandage 7 is fixed on the gas generating device 1, and the lower air bag 2 and the upper air bag 3 are communicated through the tensioning of the air bag auxiliary bandage 7.
As shown in fig. 3, 4 and 5, the opening controller 4 includes an airbag cover lower portion 8, an airbag cover upper portion 9, a valve flap 11, a gas valve 12, and a spring 13; the lower part 8 of the air bag cover plate and the upper part 9 of the air bag cover plate are placed at the pre-opened holes, and the lower part 8 of the air bag cover plate and the upper part 9 of the air bag cover plate are connected with the lower air bag 2 in a sewing way; it can be seen that there is a gap between the lower airbag cover 8 and the upper airbag cover 9, which is the thickness of the lower airbag 2, and that the pre-opening of the lower airbag 2 is clamped by the lower airbag cover 8 and the upper airbag cover 9, preventing air leakage. The upper part 9 of the airbag cover plate is provided with an air vent 10, sliding grooves are arranged around the air vent 10 of the upper part 9 of the airbag cover plate, the sliding grooves can be in a T shape, a plurality of slidable gas valves 12 are placed in the sliding grooves, the gas valves 12 have the function similar to a sliding block, and valve baffles 11 are placed in the air vent 10; the plurality of springs 13 are arranged between the gas valves 12 and the wall surface of the chute, and the plurality of gas valves 12 are pressed against the valve baffle 11 through the pressure of the springs; the valve baffle 11 is connected with the air bag auxiliary bandage 7, when the lower air bag 2 expands, the air bag auxiliary bandage 7 is tensioned, the valve baffle 11 is pulled out, and then the lower air bag 2 and the upper air bag 3 are communicated. The sponge 6 is adhered to the top of the upper air bag 3 and used for relieving impact force on personnel in case of accidents.
As shown in fig. 1, the airbag main bandage 5 and the airbag sub-bandage 7 are arranged at a spacing. The length of the airbag main bandage 5 is greater than the length of the airbag auxiliary bandage 7 or the tensile deformation of the airbag main bandage 5 is greater than the tensile deformation of the airbag auxiliary bandage 7. Therefore, when the lower air bag 2 is expanded rapidly, the contact speed of the air bag and people when the air bag is completely unfolded can be reduced in a subsection mode, and the impact injury is reduced. The number of the air bag main bandages 5 is 2-4; the number of the air bag side bandages 7 is 2-4.
As shown in fig. 5, the spring base plate structure further comprises a plurality of spring base plates 14, the plurality of spring base plates 14 are detachably mounted on the wall surface of the sliding groove, blind holes are formed in the spring base plates 14, one end of each spring 13 is fixed in the blind holes, and different spring thrusts can be preset on the spring base plates 14 according to different sliding grooves, so that the spring base plates can adapt to various conditions.
The working process is as follows:
after receiving the ignition signal, the signal receiver in the gas generating device 1 triggers the ignition mechanism to initiate the reaction of the gas generating agent, so as to generate high-temperature and high-pressure gas which is quickly filled in the lower air bag 2. At this time, since the length of the airbag sub-bandage 7 is shorter than that of the airbag main bandage 5, the airbag sub-bandage 7 is tightened first, and a reaction force is generated to the valve flap 11 on the opening controller 4, so that the valve flap 11 is separated from the opening controller 4. As shown in fig. 3, the vent hole 10 is now opened, creating communication between the lower 2 and upper 3 airbags.
The lower balloon 2 then continues to inflate until the balloon main bandage 5 is tightened and the inflation of the lower balloon 2 is complete. Due to the pressure difference between the upper bag 3 and the lower bag 2, high-temperature and high-pressure gas diffuses from the lower bag 2 into the upper bag 3. At this time, since the valve flap 11 is separated from the opening controller 4, the gas valve 12 that originally compressed the valve flap 11 gradually reduces the cross section of the vent hole 10 by the spring force, and since the sectional area where the gas flows suddenly decreases, the gas is partially blocked, and the time during this process is extremely short, which can be considered as thermal insulation, an adiabatic throttling effect is generated, so that the pressure and temperature of the gas entering the upper airbag 3 are both reduced.
After the valve baffle plate 11 is disengaged, the gas valve 12 gradually closes the vent hole 10 due to the action of the spring 13, and the thrust of the spring 13 is controlled to ensure that the vent hole 10 is completely closed when the upper air bag 3 reaches the rated pressure. At this time, two closed areas of the upper and lower air bags are formed, and simultaneously, the gas in the upper air bag 3 is ensured to have lower pressure and temperature.
The utility model provides an installation two segmentation car air bag's car, includes two segmentation car air bag, two segmentation car air bag install in the driver's cabin. The two-piece automotive airbag may be mounted in the steering wheel in the cab or inside the door or elsewhere as desired. The two-section automobile safety air bag can be arranged in an automobile cab or a motor car cab.
The present invention is not limited to the above-described embodiments, and any obvious improvements, substitutions or modifications can be made by those skilled in the art without departing from the spirit of the present invention.
