Description

Technical Field

[0001] This utility model relates to the field of airbags, specifically an adaptive airbag device. Background Technology

[0002] Airbags are primarily used to reduce injuries to occupants in traffic accidents. When a vehicle is involved in a collision, sensors inside the vehicle detect the impact force and transmit the signal to the control unit. The circuit controls the chemical substances inside the airbag to undergo a chemical reaction, producing a large amount of gas, which causes the airbag to inflate and deploy rapidly in a very short time. Adaptive airbags can use sensors and computer algorithms to intelligently and dynamically adjust the inflation amount based on the state of the occupants and the type of collision.

[0003] Existing airbags are used through a single bag. When the occupants of the vehicle are impacted, the airbag is compressed, causing the gas inside the airbag to be expelled through the variable holes on the outer surface of the airbag. The lack of gas inside the airbag reduces its protective effect. When subjected to multiple collisions, the support and protection of the airbag will decrease, making it easier to cause multiple injuries to the occupants of the vehicle.

[0004] Therefore, this utility model proposes an adaptive airbag device to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The adaptive airbag device proposed in this utility model adds an inner bladder bag inside the airbag and adds a large amount of gas to the inner bladder bag, so that the gas pressure inside the inner bladder bag is higher than the gas pressure outside the inner bladder bag.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: an adaptive airbag device, the adaptive airbag device comprising: an airbag body 1, an inner airbag 2 installed inside the airbag body 1, the inner airbag 2 dividing the interior of the airbag body 1 into a high-pressure zone 3 and a low-pressure zone 4, the interior of the inner airbag 2 being the high-pressure zone 3 and the exterior of the inner airbag 2 being the low-pressure zone 4, a plurality of air holes 5 being provided on the side wall of the inner airbag 2, a sealing structure 6 being installed inside the air holes 5, a one-way ventilation component 7 being installed inside the sealing structure 6, a first reaction box 14 being installed at the air inlet of the airbag body 1, a second reaction box 15 being installed at the air inlet of the inner airbag 2, a placement box 16 being installed on the outer surface of the first reaction box 14 and the second reaction box 15, and a placement chamber 17 being provided inside the placement box 16;

[0023] In use, the placement box 16 is placed inside the car. When not in use, both the airbag body 1 and the inner airbag 2 are stored inside the placement chamber 17. Gas is rapidly generated inside the airbag body 1 through a chemical reaction between the materials inside the first reaction chamber 14, quickly inflating the airbag body 1. Gas is rapidly generated inside the inner airbag 2 through a chemical reaction between the materials inside the second reaction chamber 15, quickly inflating the inner airbag 2. The first and second reaction chambers contain materials in different proportions, resulting in a higher pressure inside the inner airbag 2 after inflation compared to the airbag body 1, creating a high-pressure environment inside the inner airbag 2. Zone 3, the area between the airbag body 1 and the inner bag 2 is a low-pressure zone 4. When the airbag body 1 is protecting the vital parts of the body, the impact force on the occupants will put pressure on the airbag, causing the gas inside the airbag to be discharged through the variable holes on the outer surface of the airbag body 1. The lack of gas inside the airbag reduces its protective effect. When the vehicle is out of control and is subjected to multiple collisions, the gas in the inner bag 2 can provide multiple layers of support and protection for the occupants. At the same time, the one-way vent 7 can release the internal gas into the interior of the airbag body 1 to replenish the gas discharged from the airbag body 1, increasing the time that the airbag body 1 supports and protects the human body.

[0024] Example 2: Based on Example 1, a structure is provided to seal the air hole 5 and limit the one-way ventilation component 7. The sealing structure 6 includes a rubber convex ring 8, which penetrates the interior of the air hole 5 and is glued to the inner wall of the inner bag 2. A sealing gasket 9 is glued to the side wall of the rubber convex ring 8 and is glued to the outer wall of the inner bag 2. The one-way ventilation component 7 is made of rubber and penetrates the center of the rubber convex ring 8 and the sealing gasket 9.

[0025] In use, the rubber protruding ring 8 is glued to the inner wall of the inner bag 2. The one-way vent 7 is made of rubber, which makes it easy to pass through the rubber protruding ring 8 and the sealing gasket 9. The sealing gasket 9 and the rubber protruding ring 8 increase the sealing of the air hole and increase the sealing or use of the one-way vent 7.

[0026] Example 3: Based on Example 2, a one-way ventilation component 7 is provided. The one-way ventilation component 7 is I-shaped and circular. The two ends of the one-way ventilation component 7 are respectively set as a wide end 10 and a narrow end 11. The wide end 10 is located on the inner wall of the inner bag 2, and the narrow end 11 is located on the outer end of the inner bag 2. The inner wall of the wide end 10 is provided with a ring block 12. The outer diameter of the ring block 12 is the same as the inner diameter of the rubber convex ring 8. Several protrusions 13 are fixed on the surface of the narrow end 11. The protrusions 13 are evenly distributed in a ring array on the surface of the narrow end 11.

[0027] In use, the one-way vent 7, with its wide end 10 placed on the inner wall of the inner bladder 2, prevents the one-way vent 7 from passing through the vent 5 when releasing gas from the inner bladder 2. Simultaneously, as pressurized gas is released, the one-way vent 7, along with the increasing gas volume, ensures a tight seal between the ring block 12 and the interior of the rubber protrusion ring 8, preventing gas leakage. Upon impact, when the airbag comes into contact with a person and hits the narrow end 11 of the one-way vent 7, it loosens the connection between the one-way vent 7 and the rubber protrusion ring 8. Gas then flows from the interior of the inner bladder 2 through the interior of the rubber protrusion ring 8 into the interior of the airbag body 1. The protrusion 13 prevents excessive impact force from causing the one-way vent 7 to move too deeply into the inner bladder 2, blocking the hole in the rubber protrusion ring 8 with the narrow end 11, thus affecting gas leakage.

[0028] In actual use, the airbag body 1 rapidly generates gas through a chemical reaction between the internal materials of the first reaction chamber 14, quickly inflating the airbag body 1. Similarly, the inner bladder 2 rapidly generates gas through a chemical reaction between the materials of the second reaction chamber 15, quickly inflating the inner bladder 2. The rubber ring 8 is glued to the inner wall of the inner bladder 2. The one-way vent 7 is made of rubber, allowing it to pass through the rubber ring 8 and the sealing gasket 9. The sealing gasket 9 and the rubber ring 8 increase the sealing of the vents while also enhancing the sealing or usability of the one-way vent 7. The one-way vent 7 is achieved by placing the wide end 10 inside the inner bladder. The wide end 10 of the inner wall of the airbag 2 prevents the one-way vent 7 from passing through the air hole 5 when releasing gas inside the inner airbag 2. At the same time, when the pressurized gas is released, the one-way vent 7 increases with the gas, making the ring block 12 and the inside of the rubber convex ring 8 tightly fit together to prevent the gas from escaping. When the airbag comes into contact with the person, when it hits the narrow end 11 of the one-way vent 7, it loosens the one-way vent 7 and the rubber convex ring 8, and the gas is discharged from the inside of the inner airbag 2 and the inside of the rubber convex ring 8 into the inside of the airbag body 1, replenishing the gas discharged from the inside of the airbag body 1 and increasing the time that the airbag body 1 supports and protects the human body.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
