[0024] This application provides an airbag device. The airbag device of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.

[0025] refer to Figure 1 , Figure 1The diagram shown is a cross-sectional view of an exemplary embodiment of an airbag device according to this application. This application provides an airbag device 1 for use in a vehicle, including: an airbag body 2 and a protrusion 3. The protrusion 3 is disposed on the surface of the airbag body 2, and the protrusion 3 and the airbag body 2 enclose an oxygen storage chamber 4 for storing oxygen. In the event of a collision and subsequent spontaneous combustion in a new energy vehicle, if the doors are difficult to open or the occupants are unconscious, the oxygen storage chamber 4 on the airbag body 2 can provide oxygen to the occupants when their oxygen supply is depleted, thereby buying more time for rescue.

[0026] In some embodiments, the airbag device 1 includes an inflator; multiple airbag bodies 2 are connected to an inflator 5, which deploys the multiple airbag bodies 2 upon a vehicle collision. The multiple airbag bodies 2, together with the vehicle seats, form a sealed cavity to enclose the occupants. Specifically, the multiple airbag bodies 2 may include a front airbag located on the vehicle's interior panel, side airbags located on both sides of the vehicle, and a knee airbag located at the bottom of the vehicle. In other embodiments, curtain airbags may be used instead of airbags to avoid excessive impact on the occupants; this application does not limit this. After a collision, the multiple airbag bodies 2 rapidly inflate via the inflator 5. The inflated airbag bodies 2 compress against each other to form a sealed cavity with the vehicle seats. The occupants, positioned within this sealed cavity, are protected from the potentially fatal dangers of burns or smoke inhalation.

[0027] In some embodiments, the surface of the airbag body 2 facing away from the protrusion 3 includes a base layer 6 and a flame-retardant layer 7, with the flame-retardant layer 7 disposed on the outer side of the base layer 6. The airbag body 2 with the flame-retardant layer is less prone to wear and easier to cut and sew. The base layer 6 is made of nylon fabric, and the flame-retardant layer 7 is made of a non-toxic, high-temperature resistant material. The flame-retardant layer 7 serves to provide fire resistance, insulation, and sealing. This arrangement prevents occupants located within the sealed cavity from being burned or choked by smoke. In embodiments of this application, the flame-retardant layer 7 may be liquid silicone rubber; this application is not limited to this.

[0028] In some embodiments, the protrusion 3 is located within the sealed cavity. The protrusion 3 and the airbag body 2 enclose an oxygen storage cavity 4 for storing oxygen. The protrusion 3 protrudes from the surface of the airbag body 2 that forms the sealed cavity and extends into the sealed cavity. By placing the protrusion 3 within the sealed cavity, the combustion-supporting effect caused by oxygen overflowing from the oxygen storage cavity 4 to the outside of the sealed cavity can be prevented.

[0029] In some embodiments, the protrusion 3 includes a water-soluble film that is connected to the surface of the airbag body 2. The edge of the water-soluble film is connected to the surface of the airbag body 2, and an oxygen storage cavity 4 is formed between the middle of the water-soluble film and the airbag body 2. In embodiments of this application, the water-soluble film may be made of PVA (Polyvinyl Alcohol). PVA has good oxygen barrier properties, which can prevent oxygen from leaking out of the oxygen storage cavity 4 under normal circumstances. In addition, PVA is soluble in water. When the oxygen content in the sealed cavity decreases and the carbon dioxide content increases, the exhaled gas from the occupant easily condenses into water vapor on the protrusion 3, thereby melting the protrusion 3 to release the oxygen stored in the oxygen storage cavity 4, thus giving the occupant more time to wait for rescue.

[0030] refer to Figure 2 , Figure 2 The diagram shown is a schematic representation of an exemplary embodiment of the airbag device of this application. In this embodiment, there are multiple protrusions 3, which are spaced apart and arranged on the surface of the airbag body 2. The multiple protrusions 3 are spaced apart within the sealing cavity. This arrangement prevents the protrusions 3 from being compressed when the airbag body 2 expands and deploys, thus avoiding the oxygen in the oxygen storage cavity 4 from overflowing and causing a sudden increase in the oxygen content within the sealing cavity.

[0031] In some embodiments, the maximum dimension of the outer contour where the protrusion 3 connects to the surface of the airbag body 2 ranges from 1.5mm to 2mm. In the embodiments of this application, the outer contour where the protrusion 3 connects to the surface of the airbag body 2 is rectangular, with rounded corners. The maximum dimension of the rectangle can be 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, or 2.0mm. This design reduces the space occupied by the airbag body 2 when it is stored.

[0032] like Figure 3 As shown, Figure 3The diagram shows an exemplary embodiment of the alarm device of this application. The airbag device 1 includes an alarm device 8, an airbag detection device 9, a door detection device 10, and a fire detection device 11. The alarm device 8 is electrically connected to the airbag detection device 9, the door detection device 10, and the fire detection device 11. The airbag detection device 9 detects the deployment and closure status of the airbag body 2, the door detection device 10 detects the opening and closing status of the door, and the fire detection device 11 detects whether the vehicle is on fire. The alarm device 8 generates and sends a distress signal when the airbag detection device 9 detects that the airbag body 2 has deployed, the door detection device 10 detects that the door cannot be opened, and the fire detection device 11 detects that the vehicle is on fire. The airbag detection device 9, the door detection device 10, and the fire detection device 11 are installed inside the vehicle and electrically connected to the alarm device 8. When the alarm device 8 receives corresponding signals from the airbag detection device 9, the door detection device 10, and the fire detection device 11, it generates a distress signal to send a distress signal to surrounding rescue departments. This allows for the direct transmission of distress signals when a vehicle collision results in a fire and occupants are unable to escape through the doors. This enables rescue departments to take emergency measures in the shortest possible time, minimizing the losses caused by the accident.

[0033] In some embodiments, the alarm device 8 includes a controller 12, a communication module 13, and a GPS positioning module 14. The controller 12 is electrically connected to the airbag detection device 9, the fire detection device 11, the communication module 13, and the GPS positioning module 14, respectively. The GPS positioning module 14 is used to send the vehicle's location information to the controller 12. The controller 12 is used to control the communication module 13 to send a distress signal and the vehicle's location information when the airbag detection device 9 detects that the airbag body has deployed and the fire detection device 11 detects that the vehicle is on fire. The airbag detection device 9, the door detection device 10, and the fire detection device 11 send corresponding signals to the controller. After receiving signals from the airbag detection device 9 that the airbag body has deployed, the door detection device 10 that the door cannot be opened, and the fire detection device 11 that the vehicle is on fire, the controller 12 controls the communication module 13 to send a distress signal and the vehicle's location information to nearby rescue departments so that rescue departments can take emergency measures in the shortest possible time and reduce the losses caused by the accident. In addition, rescue departments can promptly remove road obstructions caused by the accident vehicle, restore road traffic as soon as possible, and avoid secondary collisions.

[0034] This application also provides a vehicle including an airbag device as described in any of the above embodiments. In the event of a vehicle fire, occupants can avoid the fatal dangers of burns or smoke inhalation, and can also obtain more oxygen in a timely manner when oxygen levels are low. The alarm device 8 can improve rescue speed and reduce losses caused by the accident.
