【Detailed ways】

Hereinafter, the present utility model will be further described in detail with reference to the drawings and specific embodiments of the specification.

Figures 1 to 9 show an embodiment of the automobile flood prevention device of the present invention. The automobile flood prevention device of this embodiment includes an airbag 1. The airbag 1 includes a main body 11, and the left and right sides of the main body 11 are provided with The first extension portion 12 extending forward of the main body portion 11, the front side of the main body portion 11 is provided with a second extension portion 13 extending forward of the main body portion 11, and an automobile wheel is formed between the first extension portion 12 and the second extension portion 13的Locating Department. As a preferred technical solution, the main body 11 is in the shape of a rectangular parallelepiped, the cross sections of the first extension 12 and the second extension 13 are circular, oval, etc., and the front end of the second extension 13 is located in front of the front end of the first extension 12. .

In the automobile flood prevention device, a first extension portion 12 extending forward is provided on the left and right sides of the main body portion 11 of the airbag 1, and a second extension portion 13 extending forward is provided on the front side of the main body portion 11. The first extension portion 12 and There is a space between the second extensions 13 to avoid the front wheels of the car while positioning the front wheels of the car to prevent the car from swinging from side to side. When used on a car whose center of gravity is close to the front of the car, the first extension 12 and the second extension 13 can effectively support the weight of the front of the car, avoid the car from tilting forward, and help to ensure the balance and stability of the car on the airbag 1.

Further, in this embodiment, the rear end of the first extension portion 12 extends to the rear of the main body portion 11, and the rear side of the main body portion 11 is provided with a third extension portion (not shown in the figure) extending to the rear of the main body portion 11 . The third extension is suitable for a small number of cars with relatively close front and rear weights, and is similar to the front end. The rear extension of the third extension and the rear ends of the two first extensions 12 can position the two rear wheels of the car. Help keep the car stable on the airbag 1.

Furthermore, in this embodiment, the airbag 1 is equipped with two side strips 6, which are respectively bonded to the left and right sides of the car, and the side strips 6 are provided with mounting parts for installing the airbag 1. 61. The two side strips 6 are glued and fixed to the left and right sides of the car without modifying the existing structure of the car. They can be used for decoration and can cover the airbag 1 in the folded state. The mounting part 61 can be a groove, Mounting holes, hooks, etc.

Further, in this embodiment, the upper surface of the main body portion 11 is provided with a first connecting structure 14 for connecting with the bottom of the automobile, and the upper and lower surfaces of the main body portion 11 are provided with an extension side 15 extending to the surroundings. A second disconnectable connection structure is provided between the main body 11 and a fold 16 is provided in the middle of each side surface of the main body 11. Among them, the first connection structure 14 may be, for example, an adhesive layer, a strap or a tension buckle, etc., which is convenient to install on the side strip 6, and the second connection structure may be, for example, a Velcro, a concealed buckle or a slip knot strap. The main body 11 of the airbag 1 is installed on the side rails 6 on the left and right sides of the bottom of the car through a first connection structure. After exhaust, the front and rear ends of the first extension 12 shrink toward the middle, and the front end of the second extension 13 shrinks backward. The airbag 1 can be folded into a block shape by folding the airbag 1 into a block, and the overall thickness can be controlled to a few millimeters in the rainy season. When it comes, it is pre-installed on the bottom of the vehicle, which will not reduce the ground clearance and affect the driving; when it needs to be inflated, because the upper part of the airbag 1 is under greater pressure, the airbag 1 first destroys the second connecting structure and expands to the left and right sides to make two The first extension part 12 moves to the left and right sides of the car, and then the first extension part 12 expands at the front and rear ends, the second extension part 13 expands toward the front end, and finally the main body part 11 expands upward, which can float the car smoothly.

Further, in this embodiment, the automobile flood prevention device further includes a liquid level sensor 2, a camera module 3, a communication module 4 (such as a GSM communication module, etc.), and a display terminal 5 (such as a mobile phone, a tablet light handheld terminal or a video in the community). Monitoring room, etc.), the liquid level sensor 2 and the camera module 3 are connected to the input end of the communication module 4, the display terminal 5 is bidirectionally connected to the communication module 4, and the inflator 17 of the airbag 1 is connected to the output end of the communication module 4.

When the car is in danger of being immersed or submerged in water, the liquid level sensor 2 will be sent to the communication module 4 to communicate with the car owner’s mobile phone to alarm. At the same time, the camera module 3 transmits video data through the communication module 4. After the mobile phone receives the alarm, the mobile phone can Instantly observe the surroundings of the car. The car owner can inflate by turning on the emergency switch of the inflator 17 (when the owner is in or around the car) or the switch button on the mobile phone interface (when the owner is away from the car). As it is damaged by water immersion, the people in the car can also float at the same time, extending the rescue time and preventing the people in the car from drowning. Of course, when circumstances permit, the owner can also drive the car away from the flooded area.

Further, in this embodiment, the upper surface of the main body portion 11 is further provided with an insulating cotton layer (not shown in the figure). Since traditional fuel vehicles generate more heat when they are running, the provision of an insulating cotton layer can prevent heat from being transferred to the airbag 1. For new energy vehicles, insulation cotton layer may not be provided.
