Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1, fig. 2 and fig. 3, a hybrid gas generator for side airbag, including some firearm 1, pass and explode medicine 2 and casing 3, casing 3 internal seal has high-pressure mixed inert gas, some firearm 1 sets up in casing 3 lower extreme, some firearm 1 upper end is provided with passes and explodes medicine 2, pass and explode 2 upper ends and be provided with first water conservancy diversion cups 4, first water conservancy diversion cup 4 lower extreme is provided with opening and inside cavity, first water conservancy diversion cup 4 upper end is provided with two ascending first scarf 5, two first scarf 5 cross in first water conservancy diversion cup 4 top, and two first scarf 5 are provided with the first water conservancy diversion hole 6 of a plurality of respectively.
Inside enclosed construction that is of casing 3, point firearm 1 lights and passes and explode medicine 2, it produces heat and a small amount of gas to pass and explode the burning of medicine 2, seal into high-pressure mixed inert gas in casing 3 in advance, original mixed compressed gas is heated the inflation in the casing, gas is at first expanded in passing the burning position of exploding the medicine, gas after the inflation flows from first water conservancy diversion hole 6 on two first scarf 5 respectively, the slant direction flows, gas in the casing 3 forms annular convection current, the gaseous pressure of buffering quick inflation, avoid rapid pressure boost to cause the damage to the generator, the internal pressure increases, it carries out the gasbag inflation to break seal structure, it uses with mixed compressed gas to pass and explode medicine 2, reduce the use of producing gas medicine, reduce the production of heat and powder, protect user's safety, and the gasbag is filled fastly.
Preferably, the upper end inside the housing 3 is provided with a second diversion cup 7, the upper end of the second diversion cup 7 is provided with an opening and is hollow inside, the lower end of the second diversion cup 7 is provided with two downward second oblique planes 8, the two second oblique planes 8 intersect at the bottom of the second diversion cup 7, and the two second oblique planes 8 are respectively provided with a plurality of second diversion holes 9. In the expansion process, the gas upwards flows into the shell along the second diversion holes 9 on the two second inclined planes 8 respectively, and the gas circularly flows in the shell 3, so that the instantly increased pressure of the gas is further relieved, and the generator is protected.
Further preferably, the first chamfer 5 and the second chamfer 8 are offset within the housing 3. First scarf 5 and the wrong back of seting up of second scarf 8, gaseous can be followed second water conservancy diversion hole 9 and rush out after flowing again, and buffering effect is good, avoids damaging the structure, and gaseous flows in casing 3 and flows out along the second water conservancy diversion hole 9 that staggers the setting, stabilizes quick aerate.
Preferably, the upper end of the igniter 1 is provided with a covering gasket 10, the booster 2 is arranged on the covering gasket 10, and the booster 2 is compressed between the first diversion cup 4 and the covering gasket 10. The booster 2 is limited in position, can be quickly ignited and generated, cannot be scattered in the shell 3 in the combustion process, is completely combusted, and provides sufficient quantity.
Further preferably, the high pressure mixed inert gas component is helium and argon. Helium and argon gas stabilize safety, can stabilize before gas generator starts and deposit in casing 3, fill the in-process at air bag, absorb the heat inflation, can accomplish safe inflation, avoid taking place the burning and even explosion danger.
Preferably, the upper end of the housing 3 is provided with a flow guiding cover 11 and the lower end of the flow guiding cover 11 is mounted in the housing 3. The air guide sleeve 11 guides the flowing direction of air, the air is further buffered and evenly flushed into the safety airbag, the top end of the air guide sleeve 11 can be provided with an installation stud for installation of the gas generator, the tail end of the stud can extend into the air guide sleeve 11 to be connected and positioned, the connection part is sealed, the structural strength is improved, and the stud can also be arranged on the outer side of the air guide sleeve 11.
Further preferably, the bottom of the air guide sleeve 11 is provided with a rupture disc 12. The rupture disc 12 can bear the pressure of high-pressure inert gas, keeps stable, and when booster 2 burns, the gas and the mixed atmospheric pressure of high-pressure inert gas that generate can exceed rupture disc 12's bearing limit, and rupture disc 12 is broken away by gas, and gas dashes out from kuppe 11, and it is fast to take place, guarantees that air bag's in time fills up.
Further preferably, a plurality of third flow guiding holes 13 are uniformly formed in the side surface of the flow guiding cover 11, and the third flow guiding holes 13 are arranged in a double-layer manner and are staggered. Third water conservancy diversion hole 13 sets up in the side, avoids gaseous straight line to rush out from the top and causes pressure too big, and third water conservancy diversion hole 13 is provided with the bilayer, can rush out a large amount of gases in the short time as far as, and third water conservancy diversion hole 13 staggers the range, reaches the effect of even inflation.
The working principle and flow of a hybrid gas generator for a side airbag according to the present invention will be described below based on the above embodiments.
After receiving a signal that the safety airbag needs to be inflated, the igniter 1 ignites the booster 2, the ignition generates heat through combustion, the inert gas in the shell 3 is mixed and absorbs the heat to expand, the air pressure in the shell 3 rises, the gas breaks the rupture disc 12 after the air pressure exceeds the bearing limit of the rupture disc 12, the gas below the first diversion cup 4 is close to the booster 2, is expanded firstly and flows out along the first diversion hole 6, because the second diversion hole 9 is not arranged opposite to the first diversion hole 6, expanded gas can circularly flow and mix in the shell 3, flow along the second diversion hole 9, balance pressure and flow in the shell 3 to play a role in buffering air pressure, the phenomenon that the gas directly rushes to cause over-high pressure to damage a structure is avoided, the gas is inflated to the safety airbag along the third diversion hole 13 on the side surface of the diversion cover 11 after entering the second diversion cup 7, and the inflation process is stable and quick.
The utility model has the advantages of simple and compact structure, adopt and pass 2 burning production heats of explosive, the casing high pressure mixed inert gas absorbs the heat after-expansion, inside atmospheric pressure rises, gaseous break piece of breaking out is aerifyd, reduce the use of producing the gas medicine, powder and heat produce fewly, can reduce the danger to the human body, in inflating the in-process, because high-pressure gas can directly be used for aerifing, gas outflow is fast, can accomplish fast and inflate the operation, first water conservancy diversion cup 4 and the cooperation of second water conservancy diversion cup 7 are used, effectively carry out the water conservancy diversion buffering, do not damage the structure, inflation process is fast and stable, and guarantee that air bag can fill, avoid the secondary injury.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
