Description

Technical Field

[0001] This utility model relates to the field of airbag technology, specifically to a rescue airbag that deploys in stages when a car falls into water. Background Technology

[0002] When a car collides, collision sensors detect the impact and transmit signals to the airbag control module. If the impact force reaches a preset value, the airbag control module triggers the gas generator, producing a large amount of gas (usually nitrogen or helium) to fill the airbag, causing it to inflate in a very short time. The airbag deploys before the occupant experiences a secondary collision with the vehicle's interior components, providing a buffer layer to reduce the impact force on the body and thus minimize the severity of injury.

[0003] A search revealed an existing patent (CN105752013B) disclosing a sunroof airbag rescue system for a submerged car, comprising a controller, a sensor assembly, an automatic sunroof opening device, and an airbag ejection device. The sensor assembly is connected to the input of the controller, while the automatic sunroof opening device and the airbag ejection device are respectively connected to the output of the controller. The sensor assembly includes a humidity and pressure sensor. The controller detects whether the car has fallen into water using the humidity and pressure sensor, and opens the sunroof via the automatic sunroof opening device. The airbag ejection device includes an airbag, and the controller ejects the airbag from the sunroof via the airbag ejection device. Following the above technical solution, it also includes an automatic seatbelt unlocking device, located at the seatbelt buckle, which the controller uses to forcibly unlock the seatbelt. Following the above technical solution, the sensor assembly also includes a vehicle collision sensor, located inside the front bumper of the car. This utility model uses a humidity and pressure sensor to more accurately and reliably determine whether a car has fallen into water. The automatic sunroof opening device and airbag ejection device can react quickly after the sensor determines that the car has fallen into water, opening the sunroof and ejecting the airbag. The buoyancy of the airbag is used to help the people inside the car leave. The trapped people do not need to think or do much, which reduces the difficulty of self-rescue for the people inside the car and ensures their safety. It is also easier and cheaper to manufacture.

[0004] However, in the above schemes, the airbags are generally ignited by electric sparks. But because the floating airbags have a large volume, a lot of medicine is needed, and the explosion reaction after short-term ignition is quite dangerous.

[0005] In view of this, this utility model proposes a rescue airbag that deploys in stages when a car falls into water. Utility Model Content

[0006] This invention proposes a staged deployment rescue airbag for vehicles falling into water, which solves the problem that in related technologies, airbags generally use electric sparks to ignite the medicine, but because the floating airbag has a large volume, a large amount of medicine is required, and the explosion reaction after short-term ignition is quite dangerous.

Therefore, multiple airbags are connected in parallel, and ignition and inflation are carried out in sequence to ensure safety.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0028] Example 1

[0029] A preferred embodiment of the step-by-step deployment rescue airbag for a car falling into water provided by this utility model is as follows: Figures 1 to 5As shown: A car submerged rescue airbag that deploys in stages includes an airbag cushion 1. An ignition module 2 is fixedly connected to one side of the airbag cushion 1. A lead box 3 is fixedly connected to the bottom of the ignition module 2 and is fixed inside the airbag cushion 1.

The air intake pipe 9 is connected to the inside of the airbag bag 12. The side of the airbag cushion 1 is fixedly connected to the floating air intake mechanism.

[0030] It should be noted that existing airbags still have certain shortcomings. Airbags generally use electric sparks to ignite the explosive, but because floating airbags have a large volume, a large amount of explosive is required, and the explosion reaction after short-term ignition is quite dangerous.

[0031] In this embodiment, the lead wire 6 and lead wire 7, which are divided inside the thick tube 4 and the thin tube 5, can be gradually ignited during the combustion of lead wire 6, so that the fuel boxes 8 on both sides are ignited one by one from one side of the lead wire box 3 inside the airbag cushion 1 to the other side, avoiding the fuel from being ignited at once. Therefore, multiple airbags are connected in parallel, and ignition and inflation are carried out in sequence to ensure safety.

[0032] In a further preferred embodiment of this utility model, the buoyancy air intake mechanism includes a fixed plate 13, a sealing plate 14, an electric push rod 15, a buoyancy hose 16, an air inlet 17, an air pump 18, a small airbag 19, a fixed air intake frame 20, and a check valve 21.

The sealing plate 14 is fixedly connected to the extension end of the electric push rod 15. The sealing plate 14 is inserted into the interior of the fixed plate 13 from one side of the fixed plate 13.

[0033] In a further preferred embodiment of the present invention, the sealing plate 14 is inserted into the side of the fixed plate 13 away from the airbag cushion 1. Both sides of the fixed plate 13 are stacked with floating hoses 16, and one end of the floating hoses 16 is fixedly connected to an air intake mechanism.

[0034] In a further preferred embodiment of the present invention, the air intake mechanism includes an air inlet 17, an air pump 18, and a small airbag 19. One end of the floating hose 16 is fixedly connected to the air inlet 17, the air pump 18 is fixedly connected inside the air inlet 17, and small airbags 19 are fixedly connected to both sides of the air inlet 17.

[0035] In this embodiment, the small airbag 19 can open one side of the fixed plate 13 after the electric push rod 15 pushes the sealing plate 14 to extend, thereby enabling the air inlet 17 to automatically float and extend to the outside of the fixed plate 13, so that the air inlet 17 can be connected to the floating hose 16 to assist in air intake and combustion.

[0036] Example 2

[0037] Based on Embodiment 1, the preferred embodiment of the present invention for a car submerged in water rescue airbag system is as follows: Figures 1 to 5 As shown: The other end of the floating hose 16 is fixedly connected to the fixed air intake frame 20. The inside of the fixed air intake frame 20 is fixedly connected to the check valve 21. The other end of the fixed air intake frame 20 is fixedly connected to the lead box 3. The floating hose 16 is connected to the inside of the fixed air intake frame 20.

[0038] In this embodiment, the backflow of gas can be prevented when the fuel box 8 is ignited by the check valve 21.

[0039] In a further preferred embodiment of the present invention, a plurality of thin tubes 5 are provided, which are equidistantly distributed on both sides of the thick tube 4. The other end of each of the multiple thin tubes 5 is fixedly connected to a fuel box 8, and the other end of each fuel box 8 is provided with an air inlet pipe 9 and an airbag 12.

[0040] In a further preferred embodiment of this utility model, the number of airbags 12 is set to several, and the several airbags 12 are equidistantly distributed inside the side airbag soft plate 11. The diameter of the lead wire 6 is larger than the diameter of the lead wire 7.

[0041] In a further preferred embodiment of this utility model, the thick pipe 4, the thin pipe 5, the lead wire 1 6, the lead wire 2 7, the fuel box 8, and the check valve 10 are all located inside the airbag cushion 1, and the air intake pipe 9 is inserted into the airbag bag 12 from the airbag cushion 1.

[0042] In this embodiment, the check valve 10 prevents the backflow of gas inside the airbag 12 during the inflation process of the airbag 12 by combustion inside the fuel box 8.

[0043] In a further preferred embodiment of this utility model, the two ends of the second lead 7 are respectively attached and connected to the first lead 6 and the fuel box 8, and the two ends of the air intake pipe 9 are respectively connected to the fuel box 8 and the air intake pipe 9.

[0044] In a further preferred embodiment of this utility model, the airbag cushion 1 and the side airbag soft plate 11 are both made of foldable nylon material, and the fuel box 8 is far away from the thick pipe 4.

[0045] The working principle of this utility model is as follows: The ignition module 2 ignites the lead wire 6 inside the lead wire box 3. During the combustion process, the lead wire 6 ignites the lead wires 7 on both sides one by one, so that the fuel boxes 8 on both sides are ignited one by one from one side of the lead wire box 3 inside the airbag cushion 1 to the other side. This avoids the risk of igniting the fuel at once. Therefore, multiple airbags are connected in parallel, and they are ignited and inflated in sequence to ensure safety. If the entire airbag sinks into the water before it is deployed, the electric push rod 15 is activated to push the sealing plate 14 to extend and open one side of the fixing plate 13. This allows the air inlet 17 to automatically float and extend to the outside of the fixing plate 13 and then float to the surface of the water. The air inlet 17 can then be connected to the floating hose 16 to assist in the intake of air and combustion.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
