Detailed ways

The preferred embodiments of the present utility model are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present utility model, and are not intended to limit the present utility model.

Embodiment 1: As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a vehicle drowning anti-sinking device of the present invention includes the bottom of the front and rear bumpers of the automobile body 1 and the bottom of the side of the car body. The anti-sinking airbag mechanism 2, the anti-sinking airbag mechanism 2 includes a strip-shaped storage box body 3, and an inflatable bag 4 in a compressed state is placed in the storage box body 3, and the inflatable bag 4 is provided with a positioning Seat 5, the positioning seat 5 is fixed to the side wall of the storage box body 3, and the storage box body 3 is provided with an ejection opening for the inflatable bag 4 to expand after inflation, and the two sides of the ejection opening The shaft is hinged with a cover door 6 that is set in half, and a torsion spring 7 that automatically closes the cover door 6 is provided between the cover door 6 and the storage box body 3; Gas supply unit 8. Through the anti-sinking airbag mechanism 2 at the bottom of the front and rear bumpers of the automobile body 1 and the bottom of the side of the vehicle body, when the automobile falls into the water, the inflatable bag 4 in the anti-sinking airbag mechanism 2 is inflated, and the inflatable bag 4 expands. Thus, the storage box automatically pops up, and under the buoyancy of the air bag, the car is effectively prevented from sinking, and under the action of the bottom of the front and rear bumpers of the car body 1 and the anti-sinking air bag mechanism 2 arranged at the bottom of the side of the car body , so that the car body 1 has a better balance, avoiding the rollover of the car, wherein under normal circumstances, the inflatable bag 4 is stored in the storage box 3, and the cover door 6 is closed by the torsion spring 7, so that the charging Air bag 4 has played the effect of protection.

The inflatable bag 4 is provided with an inflatable tube 10 , and the inflatable tube 10 is provided with a one-way air intake valve 14 .

The air supply unit 8 includes an air storage tank 9 arranged on the automobile body 1, the gas outlet end of the air storage tank 9 is connected to the inflation pipe 10 through the air guide tube 11, and the air guide tube 11 is provided with a switch valve 13. When encountering sudden situations such as drowning, turn on the inflation switch installed in the cab, the inflation of the inflatable bag, the inflation pressure and air pressure gauge to display, it is possible to adjust the peace of the car in the water according to the inflation of different airbags, when the airbag meets the requirements , the inflatable state can be turned on after closing.

The inner wall of the receiving box body 3 is provided with a limiting block 12 to prevent the cover door 6 from rotating inwardly. The end of the limiting block 12 is a circular arc end to avoid scratching the inflatable bag.

The foam filling layer between the automobile fender and the automobile interior shell of the automobile body 1 . Fill foam between car fender and car interior shell. After the car is assembled, open the hood and tailgate of the car, inject foam filler into the gap between the four fenders and other car interior shells from the inside of the car, and the foam filler will become foam after injection.

When the car receives a side impact, the foam material is soft, which can absorb energy well and reduce the damage to the occupants of the car. When the car falls into the water, the foam increases the displacement of the car, which can prevent the car from sinking into the water, protect the safety of the people in the car, and also protect the car engine from water. Furthermore, a layer of isolation layer is provided on the inner surface of the fender, and the isolation layer is located between the fender of the automobile and the foam.

For example, during maintenance, the fender may have to be removed for maintenance, and an isolation layer is provided to prevent the foam filler from sticking the fender and the car interior shell together. In the above-mentioned anti-collision and anti-submersion structure for automobiles, the isolation layer is a sponge. The sponge material is softer and easier to disassemble. On the other hand, when the foam is filled, the sponge can also maintain its original shape and will not be crushed during the foam injection and foaming process. For later maintenance, there is an installation allowance for the disassembly and assembly of the fender. In the above-mentioned automobile anti-collision and anti-sinking structure, the thickness of the sponge is 0.3-2 cm. In the above-mentioned anti-collision and anti-submersion structure for automobiles, optionally, the isolation layer is a plastic film. The plastic film can also replace the sponge to isolate the fender and the interior shell

A control button for controlling the switch valve 13 is arranged in the cab of the automobile body 1 .

Inflatable pipe 10 is connected; The driver's compartment of automobile body 1 is provided with the start button of controlling inflatable electric pump 15. In the case of drowning and other emergencies, turn on the start button installed in the cab to inflate the airbag, and the inflation pressure will be displayed on the air pressure gauge. It is possible to adjust the peace of the car in the water according to the inflation of different airbags. When the airbag meets the requirements , the inflatable state can be turned on after closing.

The inflatable bag can be inflated by an inflatable single pump. The inflatable electric pump adopts a 12V piston type high-pressure fast air pump to be powered by a 12V battery of a car. The solenoid valve is powered by a 12V DC power supply. A set of propellers 16 is installed at the rear of the car to be powered by a 12V power supply.
