[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] like Figure 1 and Figure 2 The present invention provides a car floating device, comprising a floating plate 1, an air bag 2, an air tank 3, a floating block 4, a linkage rod 5 and a mechanical valve 6. A plurality of air bags 2 are accommodated around the lower end surface of the floating plate 1, the air tank 3 is arranged in the floating plate 1, the mechanical valve 6 is arranged at the air outlet of the air tank 3, the linkage rod 5 is hinged on the floating plate 1, the floating block 4 is fixed to the linkage rod 5, the floating block 4 drives the linkage rod 5 to rotate along its hinge point through buoyancy and pushes the valve core of the mechanical valve 6 to realize the deflation of the air tank 3, the air tank 3 is deflated and all the air bags 2 are inflated, and the inflated air bags 2 protrude from the lower end surface of the floating plate 1 and form a second layer of floating body.

[0024] The floating plate 1 is made of rubber or plastic, or it is an inflatable structure like the second floating body, and a rectangular storage cavity 11 is provided in the middle of the lower end surface of the floating plate 1. The gas storage tank 3 is placed in the rectangular storage cavity 11, so that the lower end surface of the floating plate 1 is a flat plane structure. The floating block 4 can be a hollow plastic barrel.

[0025] To facilitate the installation of the gas tank 3 and the linkage rod 5, a mounting seat 7 is fixed in the rectangular storage cavity 11. The mounting seat 7 is made of hard plastic and is fixed in the rectangular storage cavity 11 by gluing. The gas tank 3 is fixedly connected to the mounting seat 7, and one end of the linkage rod 5 is hinged on the mounting seat 7.

[0026] Since the mechanical valve 6 is opened by water pressure, after the floating board 1 is laid flat on the ground, the floating board 1 is in a state of contact with the ground. To facilitate the entry of water into the rectangular receiving chamber 11, a liquid inlet groove 12 is provided on the upper surface of the lower end surface of the floating board 1, and an opening groove is provided on the mounting seat 7, which is directly opposite to the liquid inlet groove 12, so that the liquid inlet groove 12 is connected with the rectangular receiving chamber 11. After the water flows into the rectangular receiving chamber 11 through the liquid inlet groove 12, as the water level of the submerged area rises, the water pressure received by the entire floating device becomes larger, so when the valve core opening threshold of the mechanical valve 6 is reached, the mechanical valve 6 is opened.

[0027] like Figure 3 and Figure 4 , the structure of the mechanical valve 6 of the present invention is further described below.

[0028] The mechanical valve 6 includes a valve core 61 , a valve seat 62 and a spring 63 . An internal thread is provided in the gas outlet of the gas storage tank 3 , and an external thread is provided on the outer surface of the valve seat 62 . The valve seat 62 is threadedly connected in the gas outlet of the gas storage tank 3 .

[0029] An air outlet hole 60 is provided in the axial direction of the valve seat 62, and the inner and outer sides of the air outlet hole have step surfaces. The spring 63 is sleeved on the valve core 61 and placed in the air outlet hole 60 together. The valve core 61 is provided with a step surface. One end of the spring 63 abuts against the step surface on the inner side of the air outlet, and the other end abuts against the step surface on the valve core 61. The outer end of the valve core 61 extends out of the air outlet.

[0030] A first sealing gasket 64 is provided at the inner end of the valve core 61 . Under the action of the spring force, the first sealing gasket 64 abuts against the inner opening of the air outlet hole 60 and closes the air outlet hole 60 .

[0031] To further ensure the sealing effect, a second sealing gasket 65 is further provided on the valve core 61 . Similarly, under the action of the spring force, the second sealing gasket 65 abuts against the outer step surface in the air outlet 60 .

[0032] The valve core 61 is axially displaced so that the first sealing gasket 64 and the second sealing gasket 65 are away from the corresponding abutting surfaces, thereby opening the air outlet 60 .

[0033] In order to ensure the sealing between the valve seat 6 and the gas outlet, a sealing ring is provided between the valve seat 6 and the gas outlet.

[0034] The linkage rod 5 rotates along its hinge point and pushes the valve core to achieve deflation of the gas storage tank 3. In order to make the linkage rod 5 act better on the valve core 61, a bent toggle portion 51 is provided on the linkage rod 5. The toggle portion 51 is placed on one side of the valve core 61 extending out of the gas outlet (such as Figure 2 ).

[0035] An openable door 15 is provided on the upper end surface of the floating plate 1 , and the door faces the rectangular storage chamber 11 , and is used for replacing the gas storage tank 3 or inspecting the linkage rod 5 .

[0036] like Figure 5 In order to store the deflated air bag 2, a storage groove 13 is provided around the lower end surface of the floating plate 1. The deflated air bag 2 is stored and fixed in the storage groove 13, so that the lower end surface of the floating plate 1 is a flat plane.

[0037] like Figure 6 The inflatable bag 2 in the present invention includes a middle hard plastic mounting body 21 and a flexible bag 22. The flexible bag 22 is hot-pressed and glued together with the plastic mounting body 21. The plastic mounting body 21 is fixed to the middle of the storage groove 13 by gluing. The deflated flexible bag 22 is inserted into the storage groove 13, and an air inlet is provided on the flexible bag 22.

[0038] An airway is provided in the floating plate 1 , and an air pipe is provided in the airway. The air outlet of the air storage tank 3 is connected to the air inlet ports in all the inflatable bags 2 through the air pipe.

[0039] like Figure 7The air storage tank 3 is deflated to inflate all the air bags 2. The inflated air bags 2 protrude out of the lower end surface of the floating plate 1 and form a second layer of floating body, thereby increasing the overall buoyancy of the device.

[0040] Four tire grooves 14 are provided on the upper end surface of the floating plate 1. When in use, the wheels drive into the tire grooves 14 to ensure the positioning effect between the device and the vehicle.

[0041] When used in rainy seasons, the product is first laid on the parking space, and then the device is fixed to the ground (such as a reversing pile or a pillar) by a rope, and the vehicle is driven to the position corresponding to the tire, that is, the wheel enters the tire groove 14. In heavy rain, as the water level rises, the buoyancy supported by the floating plate 1 is not enough to float the vehicle. When the valve core opening threshold of the mechanical valve 6 is reached, the mechanical valve 6 is opened, and the gas in the air tank enters all the inflatable bags 2. The volume of the inflatable bags 2 expands and protrudes out of the storage groove 13. The inflated inflatable bags 2 and the floating plate 1 generate buoyancy together to float the vehicle. The rope fixes the device to the ground so that the floating device drifts away. In order to prevent the floating plate 1 from detaching from the vehicle, the floating plate 1 is tied to the tire so that they are relatively fixed to the vehicle chassis. A corresponding deflation valve is also provided on the inflatable bag 2 for deflation.

[0042] The present invention decomposes the buoyancy part into two floating supports. The required buoyancy will automatically increase with the increase of liquid level, and no extra space will be used. It can be used between adjacent garages. Different vehicle weights require different buoyancy, but the ground clearance height is fixed. Automatic inflation is used to form the second floating body, so it can adapt to more types of vehicles. In the event of severe weather such as typhoons, rainstorms, floods or seawater backflow, it ensures that vehicles are not flooded, reduces people's property losses, and does not need to increase high-altitude public roads to affect people's lives. After the disaster, it is easy to store and reuse.

[0043] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
