Abstract
Description
Technical Field
[0001] The invention relates to the technical field of automobile safety airbags, in particular to an automobile safety airbag structure. Background Art
[0002] From the proposal of the concept of airbags in 1952 to the actual application of airbags in automobiles in 1980, when science and technology were not so developed at that time, after 28 years of long and difficult trials, the application of airbags has greatly reduced the severity of injuries caused by accidents and improved the passive safety of automobiles. Today, it has become a standard feature of automobiles and an important symbol of a car's safety factor.
[0003] As an auxiliary configuration for the passive safety of the vehicle body, airbags are increasingly receiving attention. When a car collides with an obstacle, it is called a primary collision, and when the passenger collides with the internal components of the car, it is called a secondary collision. After the primary collision and before the secondary collision, the airbag quickly opens a gas-filled airbag, causing the passenger to fall on the airbag when moving due to inertia. At this time, through the viscous damping effect of the gas, the passenger's forward movement energy is absorbed and dissipated, thereby alleviating the impact on the passenger and absorbing the collision energy, reducing the degree of injury to the passenger, and the over-pressure gas in the airbag is discharged through the airbag vent without injuring the passenger.
[0004] At present, the deflation holes of existing automobile airbags are always in an open state, and the deflation volume is large and cannot be changed, which leads to the general retention of the internal pressure of the airbag. After the airbag is opened, the internal gas is discharged at a fast speed, which will affect the protection effect to a certain extent. In addition, after a collision, the occupant's face is easily pressed against the airbag and he or she becomes unconscious. The airbag has a strong sealing performance, which easily causes the occupant to suffocate and affect the safety of the occupant. When the internal gas leaks to a certain extent, the supporting capacity of the airbag will decrease. At this time, it is possible that the head of the occupant who is unconscious on the airbag will slide off the airbag, causing secondary injury to the occupant. At the same time, the airbag located at the main driver's seat is mostly a circle slightly larger than the steering wheel. When the airbag is ejected, there is still a large area between the steering wheel and the door that cannot be covered by the main driver's airbag. If an oblique collision occurs, the occupant's head may rush obliquely to the area not covered by the airbag under the action of inertia and collide with the center console at that location. Therefore, the protection of the traditional main driver's airbag still needs to be improved. Summary of the invention

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] For an embodiment of the present invention, please refer to Figures 1 to 5 The automobile airbag structure includes a main airbag 1, which can be in an oblate or square shape, and an air inlet hole 101 is provided in the middle of the lower surface of the main airbag 1, and deflation components 10 are fixedly installed on both sides of the lower part of the main airbag 1, and the deflation component 10 includes a deflation pipe 3 and an adaptive deflation mechanism 6, the deflation pipe 3 is fixed on the main airbag 1, and a through deflation hole 301 is opened in the middle of the deflation pipe 3 along the axial direction, and the adaptive deflation mechanism 6 is fixedly installed on the outer end of the deflation pipe 3; The adaptive air release mechanism 6 includes an exhaust nozzle 601 fixedly mounted on the outer end of the air release pipe 3. The exhaust nozzle 601 is square in shape, and an exhaust cavity 602 with an opening at the lower side is provided inside the exhaust nozzle 601. The exhaust cavity 602 is connected to the air release hole 301. Baffles 603 are installed on both sides of the exhaust chamber 602 through a rotating shaft. The baffles 603 on both sides are symmetrically distributed, and a leakage gap 605 is left between the baffles 603 on both sides. Connecting springs 604 are fixedly installed on both sides of the exhaust chamber 602, and one end of the connecting springs 604 on both sides is fixedly connected to the baffles 603 on both sides respectively.
[0023] In specific use, when a car collides, the gas generator located in the steering wheel begins to quickly inflate the main airbag 1 through the air inlet 101, so that the main airbag 1 expands and pops open. At this time, the head of the occupant will also hit the main airbag 1 due to inertia. In this process, the over-pressure gas in the main airbag 1 can be discharged outward through the bleed hole 301 in the bleed pipe 3 and the bleed gap 605 between the two baffles 603. In addition, under the obstruction of the baffles 603 on both sides, the internal gas can be slowly discharged. When the main airbag 1 is subjected to a greater impact force from the occupant, the internal pressure will also increase. At this time, the gas will accelerate through the bleed hole 301. 01 and the exhaust chamber 602, the baffles 603 on both sides can be rotated outward around the rotating axis, so as to stretch the baffles 603 on both sides outward and stretch the connecting spring 604 to a certain extent. At this time, the air discharge gap 605 between the two baffles 603 is increased, which can accelerate the discharge of the internal gas, and the size of the air discharge gap 605 increases with the increase of the impact force. Therefore, the purpose of automatically adjusting the air discharge speed according to the size of the air pressure in the main airbag 1 can be achieved, and then the air discharge amount can be adjusted, which can effectively prevent the air discharge from being too fast or too slow, thereby improving the internal pressure retention of the main airbag 1, and can improve the protection effect to a certain extent.
[0024] As an embodiment of the present invention, please refer to Figures 1 to 7 , automobile safety airbag structure, the inside of the deflation pipe 3 is provided with one-way air intake mechanisms 9 on both sides of the deflation hole 301, a first inflation hose 7 is fixedly mounted on one of the one-way air intake mechanisms 9, an anti-suffocation mechanism 4 is provided in the middle of the upper surface of the main airbag 1, and one end of the first inflation hose 7 away from the deflation pipe 3 is connected to the anti-suffocation mechanism 4; The one-way air intake mechanism 9 includes a reverse filling hole 901 provided on both sides of the inside of the deflation pipe 3, a sealing hole 904 is provided at one end of the reverse filling hole 901, the diameter of the sealing hole 904 is smaller than the diameter of the reverse filling hole 901, and the sealing hole 904 is communicated with the deflation hole 301, and the other end of the reverse filling hole 901 extends to the outer surface of the deflation pipe 3, one end of the first inflation hose 7 and the second inflation hose 8 are respectively plugged and fixed in the reverse filling holes 901 on both sides, and a return spring 902 is installed at one end of the first inflation hose 7 and the second inflation hose 8 plugged in the reverse filling hole 901, and a spherical sealing plug 903 is installed at one end of the return spring 902 close to the deflation hole 301, and the sealing plug 903 is slidably installed in the reverse filling hole 901, and the sealing plug 903 is plugged in the sealing hole 904, and the diameter of the spherical sealing plug 903 is larger than the diameter of the sealing hole 904; The anti-suffocation mechanism 4 includes an inflatable bag 401 sewn and fixed to the middle part of the upper surface of the main airbag 1. The material of the inflatable bag 401 is the same as that of the main airbag 1. A plurality of long raised strips 402 are fixedly arranged on the upper surface of the inflatable bag 401.

The end of the first inflatable hose 7 away from the deflation pipe 3 is fixedly connected to the inflatable bag 401, and the inflatable bag 401 is connected to the reverse filling hole 901 through the first inflatable hose 7.
[0025] During specific use, when the main airbag 1 is not inflated, the inflatable bag 401 and the raised strip 402 are folded together with the main airbag 1, and when the main airbag 1 is inflated, the inflatable bag 401 and the raised strip 402 will unfold with the main airbag 1, and when the gas in the main airbag 1 is discharged through the air leakage hole 301, the air pressure can push the sealing plug 903 in the direction of the connecting spring 604, so that the sealing plug 903 slides a certain distance in the anti-filling hole 901 and compresses the return spring 902 to a certain extent. At this time, part of the gas in the air leakage hole 301 can enter the first inflation hose 7 through the sealing hole 904 and the anti-filling hole 901, thereby inflating the inflatable bag 401 and causing the inflatable bag 401 and the raised strip 402 to expand and bulge. Both the ventilation gap 403 and the ventilation hole 404 are formed, so when the occupant's face is pressed against the inflatable bag 401, the raised strip 402 can prop up a certain gap between the occupant's face and the inflatable bag 401, and the ventilation gap 403 and the ventilation hole 404 can provide air circulation space for the occupant's breathing, ensuring that the occupant breathes smoothly, thereby effectively preventing suffocation caused by the occupant's face being pressed against the main airbag 1 when he or she is unconscious, further improving the protection capability of the airbag, and when a certain amount of gas is filled in the inflatable bag 401, the return spring 902 can use its rebound force to reinsert the sealing plug 903 into the sealing hole 904, so as to seal the inflatable bag 401 and prevent the gas in the inflatable bag 401 from leaking, thereby ensuring the continuity of the anti-suffocation function.
[0026] As an embodiment of the present invention, please refer to Figures 1 to 5 as well as Figures 8 to 9 , automobile safety airbag structure, a second inflatable hose 8 is fixedly installed on another one-way air intake mechanism 9, the first inflatable hose 7 and the second inflatable hose 8 are both arranged inside the main airbag 1, and the first inflatable hose 7 and the second inflatable hose 8 are both made of soft materials, and anti-slip mechanisms 5 are arranged on both sides of the upper surface of the main airbag 1, and the anti-slip mechanisms 5 on both sides are symmetrically distributed on both sides of the anti-suffocation mechanism 4, and the end of the second inflatable hose 8 away from the deflation pipe 3 is connected to the anti-slip mechanism 5; The anti-slip mechanism 5 includes a protective bag 501 sewn and fixed to the outer side of the upper surface of the main airbag 1. The material of the protective bag 501 is the same as that of the main airbag 1. The protective bags 501 on both sides are symmetrically distributed on both sides of the inflatable bag 401. The shape of the protective bag 501 close to the inflatable bag 401 is arc-shaped, and a plurality of anti-slip protrusions 502 are fixedly provided on the arc surface of the protective bag 501. The plurality of anti-slip protrusions 502 are distributed in a circular array along the axis of the arc surface. The interiors of the protective bag 501 and the anti-slip protrusions 502 are both hollow. The end of the second inflatable hose 8 away from the deflation pipe 3 is fixedly connected to the protective bag 501, and the protective bag 501 is connected to the reverse filling hole 901 through the second inflatable hose 8.
[0027] During specific use, when the main airbag 1 is not deployed, the protection bag 501 and the anti-slip protrusion 502 are folded together with the main airbag 1, and when the main airbag 1 is deployed, the protection bag 501 and the anti-slip protrusion 502 will also unfold with the main airbag 1, and when the gas in the main airbag 1 is discharged through the air vent 301, part of the gas will also enter the second inflation hose 8 through the one-way air intake mechanism 9 on the corresponding side, thereby inflating the protection bag 501 through the second inflation hose 8, and expanding the protection bag 501 and the anti-slip protrusion 502. Similarly, the one-way air intake mechanism 9 can also prevent the gas in the protection bag 501 from leaking. At this time, the expanded protection bag 501 and the anti-slip protrusion 502 can provide a certain limit block for the occupant's head, which can prevent the head from sliding from the side to a certain extent, thereby effectively preventing secondary injuries to the occupant and further ensuring the safety of the occupant.
[0028] As an embodiment of the present invention, please refer to Figure 1 to Figure 2 as well as Fig.10 , the automobile airbag structure, the outer side of the main airbag 1 is sewn and fixed with a secondary airbag 2, the shape of the secondary airbag 2 is arc-shaped, the side of the secondary airbag 2 close to the main airbag 1 is provided with an air guide channel 202, and the interior of the secondary airbag 2 is connected with the interior of the main airbag 1 through the air guide channel 202, and the upper surface of the secondary airbag 2 is provided with a plurality of bending grooves 201, the bending grooves 201 penetrate the secondary airbag 2 in the longitudinal direction, the cross-sectional shape of the bending grooves 201 is arc-shaped, and the diameters of the plurality of bending grooves 201 decrease successively from one side close to the main airbag 1 to the other side.
[0029] When in use, when the main airbag 1 is not deployed, the secondary airbag 2 is also folded together with the main airbag 1. When the main airbag 1 is deployed, the secondary airbag 2 will be deployed along with the main airbag 1, and the gas inside the main airbag 1 will also quickly enter the secondary airbag 2 through the air guide channel 202, so that the secondary airbag 2 will be quickly deployed on one side of the steering wheel. At this time, the outer side of the secondary airbag 2 is against the inner side of the door, so that the area between the steering wheel and the door can be covered. If the head of the occupant hits this area, the secondary airbag 2 will first cushion the head to a certain extent, and the secondary airbag 2 will also cushion the head to a certain extent after the impact force is greater than that of the secondary airbag 2. Under the action of the multiple bending grooves 201, the arc-shaped auxiliary airbag 2 will be further bent, and since the diameters of the multiple bending grooves 201 decrease successively from one side close to the main airbag 1 to the other side, the bending radius of the auxiliary airbag 2 from the inside to the outside can become smaller and smaller, thereby wrapping the head, thereby preventing the head from colliding with the gap between the auxiliary airbag 2 and the door, thereby achieving the purpose of improving the protection area and protection ability of the airbag, and effectively preventing the occupant's head from hitting the area not covered by the airbag, further ensuring the personal safety of the occupant.
