Technical Field

[0001] This utility model relates to the field of air cushion technology, and in particular to an inflatable air cushion kit. Background Technology

[0002] When small cars encounter urban flooding, many vehicles are often submerged or damaged by water, resulting in serious economic losses. Traditional flood control equipment, such as sandbags or flood barriers, suffers from problems such as difficulty in transportation and slow response time, making them ineffective in dealing with sudden flooding.

[0003] To address the aforementioned issues, a search revealed Chinese patent application CN201922402179.4, which discloses a car flood-proof air cushion device. This device includes a first air cushion, a second air cushion, and a third air cushion, which are interconnected. This patent places the device at a designated location under the car and inflates it, supporting the car when there is a certain amount of water accumulation on the road surface. However, this patent has the following shortcomings: because there is no connecting or traction mechanism between the device and the vehicle or external structure, the device and vehicle are highly susceptible to separation, potentially causing the vehicle to fall and be submerged. Furthermore, the vehicle, which is floated on the water by the device, is prone to drifting with the current, potentially leading to collisions with external structures. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an inflatable air cushion kit.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An inflatable air cushion kit includes an air pump and a composite kit suitable for use under a vehicle chassis. The composite kit includes, from top to bottom, a top plate, an air cushion body, and a bottom plate. The upper and lower surfaces of the air cushion body are respectively fixedly connected to the corresponding sides of the top plate and the bottom plate.

[0010] As a further embodiment of this utility model: the air cushion body is composed of an independently set front air chamber, a main air chamber and a rear air chamber from front to back, and the top surfaces of the front air chamber, the main air chamber and the rear air chamber are respectively fixedly connected with air inlets and air pressure gauges.

[0011] As a further improvement of this utility model, the bottom outer wall of the base plate is provided with a grid-shaped drainage system.

[0012] As a further improvement of this utility model, a warning strip is fixedly connected to the outer side of the base plate.

[0013] As a further improvement of this utility model, an air vent is fixedly connected to the top surface of the air cushion body.

[0014] As a further improvement of this utility model, a pressure gauge is fixedly connected to the top surface of the air cushion body.

[0015] Compared with the prior art, the present invention provides an inflatable air cushion kit, which has the following beneficial effects:

[0016] 1. This inflatable air cushion kit, through the inclusion of a composite kit adapted to the vehicle chassis and other structures, can be secured to the four wheels of the vehicle, thereby improving the tightness of the connection between the composite kit and the vehicle.

[0026] Example 1

[0027] An inflatable air cushion kit, such as Figure 1-2 and Figure 4 As shown, the device includes a small air pump and a composite kit. The composite kit consists of a top plate 1, an air cushion body 2, and a bottom plate 3 from top to bottom. The top and bottom sides of the air cushion body 2 are welded to the corresponding sides of the top plate 1 and the bottom plate 3, respectively. The composite kit is small in size when folded, does not take up too much space, and is easy to carry.

[0028] Among them, the top plate 1, which is used to contact the vehicle chassis, can be a rigid polycarbonate bearing plate, which can effectively prevent the air cushion body 2 from contacting the vehicle chassis and reduce the damage caused by vehicle vibration and friction.

[0029] The air cushion body 2 can be made of materials such as rubber, high-strength PVC coated fabric, or Hyperon. The height of the air cushion body 2 after inflation can be 15-30cm.

[0030] Among them, the base plate 3 can be a multi-segment foldable plastic plate and a high-strength Kevlar fiber composite layer welded to the bottom surface of the plastic plate, which has the advantages of puncture resistance and impermeability, and plays a protective role for the upper air cushion body 2.

[0031] Preferred, such as Figure 1 As shown, the top plate 1 is sized to match the car chassis; the air cushion body 2 and the bottom plate 3 are the same size, and the front end of the air cushion body 2 extends 10-30cm beyond the front end of the top plate 1, preferably 10cm, to match the front weight of the vehicle; the sides and rear end of the air cushion body 2 extend 10-30cm beyond the sides and rear end of the top plate 1, respectively, preferably 10cm; the outer dimensions of the air cushion body 2 are larger than the size of the car, which can effectively increase buoyancy and improve the stability of the equipment during use, thus protecting the vehicle and preventing damage when the vehicle collides with surrounding buildings.

[0032] Furthermore, an air inlet 4 is welded to the top surface of the air cushion body 2; the air pump and the air cushion body 2 are connected through the air inlet 4. When in use, the air pump is powered by the vehicle's power supply to inflate the air cushion body 2.

[0033] Preferably, a pressure gauge 5 is welded to the top surface of the air cushion body 2; during inflation and use, the pressure gauge 5 displays the changes in air pressure inside the air cushion body 2 in real time, making it easier for people to understand and reduce the occurrence of safety hazards.

[0034] Furthermore, the bottom outer wall of the base plate 3 [i.e., the plastic plate] is provided with a grid-shaped drainage groove 301 to prevent water accumulation on the bottom surface.

[0035] Two auxiliary fixing structures are respectively provided on both sides of the base plate 3 located at the front and rear tire positions of the vehicle. The auxiliary fixing structures include a fixing ring 7 welded to one side of the base plate 3, an elastic rope 8 attached to the outer wall of the fixing ring 7, a hook 801 fixed to one end of the elastic rope 8 by bolts, and at least two fixing straps 9 welded to one side of the base plate 3 in a U-shape.

[0036] Preferably, one end of the elastic cord 8 passes through the area covered by the fixing strap 9;

[0037] During use, the elastic rope 8 is pulled out from the fixing strap 9, and its elasticity is used to wrap around the tire and hook it with the hook 801, thereby fixing the four points of the composite kit to the vehicle itself, improving the stability of the equipment when used with the vehicle. Alternatively, the elastic rope 8 can be wrapped around the tire once and then hooked with the hook 801 to a surrounding fixed structure such as a railing, thereby fixing the vehicle's position and preventing the vehicle from being passively displaced during floods.

[0038] Preferably, a warning strip 6 is adhered to the outer side of the base plate 3; this facilitates vehicle owners in quickly locating their vehicles at night or in poor lighting conditions, improving the functionality of the equipment.

[0039] Working principle: The air cushion is placed under the vehicle chassis and inflated by powering the air pump with the vehicle's power supply. Then, the elastic rope 8 is pulled out from the fixing strap 9 and wrapped around the tire using its elasticity. It is then hooked with the hook 801, thereby fixing the four points of the composite kit to the vehicle itself. Alternatively, the elastic rope 8 can be wrapped around the tire once and then hooked with the hook 801 to fix the vehicle's position to surrounding fixed structures such as railings.

[0040] During floods, the composite kit will use the buoyancy of the water to lift the car, thus ensuring that the vehicle is not submerged; when storing, use an air pump to suck out the air from the air cushion body 2, and then fold it.

[0041] Example 2

[0042] An inflatable air cushion kit, such as Figure 3 As shown, in order to provide another structure for the air cushion body 2, this embodiment makes the following improvements based on embodiment 1: the air cushion body 2 is composed of an independently set front air chamber 201, a main air chamber 202 and a rear air chamber 203 from front to back, which reduces the risk of local high pressure and improves the pressure bearing capacity and safety of use; and air inlets 4 and pressure gauges 5 are welded to the top surfaces of the front air chamber 201, the main air chamber 202 and the rear air chamber 203 respectively; improving the safety of each independent air chamber during use and the inflation and deflation efficiency.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
