AI Technical Summary
Existing car-into-water escape tools are limited in function, rely on manual operation, and are cumbersome to operate, increasing the risk of escape failure.
The design integrates the window-breaking function with the buoyancy airbag. By integrating the airbag and the cone-shaped part into the vehicle seat through the gas generator, a modular escape with a single action is achieved. When the airbag is ignited, it provides buoyancy and breaks the window, and the control unit automatically triggers the escape device.
When a vehicle falls into water, the integrated design enables an escape process within the smallest possible time unit, improving escape efficiency, providing comprehensive occupant protection, and reducing operational steps and the risk of failure.

Abstract
Claims
1. An automotive water escape device, characterized by, include: The gas source body includes a gas generator (3) and a detachable mounting structure (5). The gas generator (3) is used to ignite in response to an ignition command, and the detachable mounting structure (5) is used to detachably fix the gas generator (3) inside the vehicle seat (6). An airbag (4) is installed inside a vehicle seat and is connected to a gas generator (3). The airbag (4) is configured to inflate and pop out from the side of the vehicle seat (6) when the gas generator (3) is detonated to form a buoyancy device. The pointed cone (31) is fixedly installed on the gas source body and is used to break windows.
2. The automobile water escape device according to claim 1, wherein The airbag (4) is configured to form a ring structure after inflation.
3. The automobile water escape device according to claim 1, wherein: The pointed cone (31) is fixedly mounted on the gas generator (3) or on the detachable mounting structure (5).
4. A vehicle characterized by: The device includes a vehicle body, a seat (6) installed inside the vehicle body, and a vehicle water escape device as described in any one of claims 1-3. The airbag (4) and the air source body are installed inside the vehicle seat (6). The device also includes a water immersion sensor and a control unit. The water immersion sensor (1) is installed outside the vehicle body and is used to detect the vehicle's water immersion status. The control unit (2) is installed inside the vehicle body and is connected to the water immersion sensor (1) and the gas generator (3) and is used to issue an ignition command when a water immersion signal is detected.
5. The vehicle of claim 4, wherein: The seat (6) includes a frame (61), a foam (62) wrapped around the frame (61), and a skin covering the outside of the foam (62). The gas generator (3) is detachably fixed to the frame (61) through a detachable mounting structure (5). The skin on the side of the seat (6) is provided with weakened stitching, which allows the airbag (4) to tear the foam (62) and stitching and pop out after inflation.
6. The vehicle of claim 5, wherein: The weakened stitching is located on the inner skin of the seat (6).
7. The vehicle of claim 5, wherein: The weakened stitching is located on the outer skin of the seat (6).
8. The vehicle of claim 5, wherein: The detachable mounting structure (5) includes a mounting bracket (51) and a pin (52). The mounting bracket (51) is fixedly connected to the gas generator (3). At least two pins (52) are spaced apart along the vertical direction of the mounting bracket (51). The frame (61) is provided with a socket (611) that cooperates with the pin (52).
9. The vehicle of claim 8, wherein: The frame (61) is provided with a horizontal pin hole (612), which is located at the top of the uppermost pin (52). A locking pin (53) is horizontally inserted in the pin hole (612) to limit the vertical displacement of the mounting bracket (51). A pull strap (54) is also fixedly provided on the locking pin (53).
10. The vehicle of claim 4, wherein: The control unit (2) is a vehicle airbag controller.
