Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Example 1: as shown in fig. 1, fig. 2, fig. 3 and fig. 4, the drowning anti-sinking device for vehicle of the present invention comprises an anti-sinking airbag mechanism 2 disposed at the bottom of a front bumper and a rear bumper of an automobile body 1 and at the bottom of a side surface of the automobile body, wherein the anti-sinking airbag mechanism 2 comprises a strip-shaped storage box body 3, an airbag 4 in a compressed state is disposed in the storage box body 3, a positioning seat 5 is disposed on the airbag 4, the positioning seat 5 is fixed to a side wall of the storage box body 3, an ejection opening for ejecting the inflated airbag 4 is disposed on the storage box body 3, two lateral shafts of the ejection opening are hinged with a cover door 6 which is arranged oppositely, and a torsion spring 7 for automatically closing the cover door 6 is disposed between the cover door 6 and the storage box body 3; the automobile body 1 is provided with an air supply unit 8 for supplying air to the inflatable bag 4. Through the preceding rear bumper bottom of automobile body 1 and set up the gasbag mechanism 2 that prevents sinking of automobile body side bottom, when the car falls into water, inflate through the gas cell 4 to preventing sinking in the gasbag mechanism 2, thereby the gas cell 4 takes place the inflation and auto-eject in the storage box, under the buoyancy effect of gas cell, the car has effectively been avoided sinking, and at the preceding rear bumper bottom of automobile body 1 and set up under the effect of the gasbag mechanism 2 that prevents sinking of automobile body side bottom, make automobile body 1 have better equilibrium, avoid the car to take place to turn on one's side, wherein under normal condition, gas cell 4 is accomodate in storage box body 3, wherein the door 6 is closed at torsional spring 7, thereby play the effect of protection to gas cell 4.

An inflation tube 10 is arranged on the inflatable bag 4, and a one-way air inlet valve 14 is arranged on the inflation tube 10.

The air supply unit 8 comprises an air storage tank 9 arranged on the automobile body 1, the air outlet end of the air storage tank 9 is connected with an inflation tube 10 through an air duct 11, and a switch valve 13 is arranged on the air duct 11. When the emergency condition such as drowning occurs, an inflation switch arranged in a cab is turned on, the inflation of an inflation bag and an inflation pressure air pressure gauge are used for displaying, the balance of the automobile in water can be adjusted according to the inflation of different air bags, and when the air bags meet the requirement, the inflation state can be turned on after the air bags are turned off.

Be equipped with on the 3 inner walls of containing box body and prevent the stopper 12 of covering door 6 internal rotation, the tip of stopper 12 is the circular arc end, avoids fish tail gas cell.

The automobile body 1 is a foam filling layer between an automobile fender and an automobile interior trim shell. And filling foam between the automobile fender and the automobile interior trim shell. After the automobile is assembled, the engine cover and the rear box cover of the automobile are opened, the foam filling agent is injected into gaps between the four fenders and other automobile interior trim shells from the inside of the automobile, and the foam filling agent becomes foam after being injected.

When the automobile receives side impact, the foam material is soft, so that a good energy absorption effect can be achieved, and the injury to people in the automobile is reduced. When the automobile falls into water, the foam increases the water discharge of the automobile, can prevent the automobile from sinking into the water bottom, protects the safety of personnel in the automobile, and simultaneously protects the water inlet of an automobile engine. Furthermore, an isolation layer is arranged on the inner surface of the fender and is positioned between the automobile fender and the foam. The isolation layer passes through the sticky dismouting that is in the same place with the fender, pours into the foam into, and the isolation layer is in the same place with the complete antithetical couplet of foam, does not influence later stage fender's dismouting like this. If during maintenance, the fender probably will tear the maintenance down, has set up the isolation layer, has avoided foam filling agent to stick fender and automotive interior shell together. In the above anti-collision and anti-sinking structure for the automobile, the isolation layer is made of sponge. The sponge is softer and is convenient to disassemble and assemble. On the other hand, when foam is filled, the sponge can keep the original shape and can not be flattened in the foaming process of foam injection. And installation allowance is reserved for the disassembly and assembly of the fender during later maintenance. In the above anti-collision and anti-sinking structure for the automobile, the thickness of the sponge is 0.3-2 cm. In the above anti-collision and anti-sinking structure for an automobile, optionally, the isolation layer is a plastic film. The plastic film can also replace sponge to play the role of isolating the fender from the interior trim shell

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

Embodiment 2, as shown in fig. 5 and 6, differs from embodiment 1 in that the gas supply unit 8 is an inflation electric pump 15, and the inflation end of the inflation electric pump 15 is connected to the inflation tube 10 of the inflatable bag 4; the driver's cab of the vehicle body 1 is provided with a start button for controlling the charge pump 15. When the automobile is in a drowning emergency, a starting button arranged in a cab is started, the inflation of the inflatable bag is displayed by an inflation pressure air gauge, the balance of the automobile in water can be adjusted according to the inflation of different air bags, and when the air bags meet requirements, the inflatable state can be started after the air bags are closed.

The inflatable bag can be inflated by an inflatable single pump, the inflatable electric pump adopts a 12V piston type high-pressure quick air pump to realize power supply by a 12V storage battery of the automobile, the electromagnetic valve adopts 12V direct current power supply, and a set of propeller 16 is arranged at the tail part of the automobile and is supplied with power by a 12V power supply.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
