[0001] This utility model relates to the field of car cover technology, and in particular to a three-layer inflatable car cover. Background Technology
[0002] Car covers, as a protective tool for automobiles, are commonly used by families without garages for daily outdoor parking. They can reduce interior aging and paint fading caused by direct ultraviolet radiation. In rainy areas, they can reduce the risk of rainwater corrosion on the metal parts of the car body. In seasons with many fallen leaves, they can prevent the accumulation and fermentation of fallen leaves from damaging the paint. They can also provide basic protection in severe weather such as hail and sandstorms.
[0003] However, traditional non-inflatable car covers are made of thin materials and have weak protection against hail and hard object impacts. They are also in direct contact with the car body and are easily scratched by wind. While existing inflatable car covers have a cushioning layer, they are not very effective against impacts from sharp objects and are easily damaged. Therefore, this application proposes a three-layer inflatable car cover. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a three-layer inflatable car cover.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] This utility model provides a technical solution: such as Figure 1-4 As shown, a three-layer inflatable car cover includes a car cover body 1. The two outer sides of the car cover body 1 are provided with first connecting seams 2. Each first connecting seam 2 is provided with a rain guard 6 at the top. The two outer sides of the car cover body 1 are provided with second connecting seams 7. The two outer sides of the car cover body 1 are provided with semi-enclosed covers 8. Each semi-enclosed cover 8 is provided with a cover outside the corresponding second connecting seam 7. The car cover body 1 includes an outer protective layer, an expansion layer, and an inner protective layer. The outer protective layer is provided with a cover on the top surface of the expansion layer, and the inner protective layer is provided with a cover on the bottom surface of the expansion layer. The expansion layer includes an inflatable airbag 11, and each semi-enclosed cover 8 is connected to the inflatable airbag 11.
[0023] It should be noted that the car cover body 1 is adapted to the outline shape of the car, and the first connecting seam 2 facilitates the opening of the driver and passenger doors and allows people to enter the car. The rain guard 6 can reduce the damage of rain and hail to the driver and passenger doors. The second connecting seam 7 is used to pass through the rearview mirror. The semi-enclosed cover 8 is connected to the inflatable airbag 11 of the car cover body 1. The outer side of the semi-enclosed cover 8 is stitched so that the top thread and bottom thread intertwine to form a knot, which is used to enhance the support strength of the semi-enclosed cover 8. The semi-enclosed cover 8 can protect the rearview mirror without affecting the folding of the rearview mirror.
[0024] Furthermore, the outer protective layer includes an upper Oxford cloth layer 9 and a first PVC layer 10, with the first PVC layer 10 installed on the top surface of the inflatable airbag 11, and the upper Oxford cloth layer 9 installed on the top surface of the first PVC layer 10.
[0025] Furthermore, the inner protective layer includes a second PVC layer 12, and the second PVC layer 12 is installed on the bottom surface of the inflatable airbag 11, and a lower Oxford cloth layer 13 is installed on the bottom surface of the second PVC layer 12.
[0026] The first PVC layer 10 and the second PVC layer 12 can protect the inflatable airbag 11 and reduce its leakage. The upper Oxford cloth layer 9 and the lower Oxford cloth layer 13 can effectively reduce the damage to the inflatable airbag 11 from external sharp objects, protect the normal use of the inflatable airbag 11, and the inflatable airbag 11 can effectively buffer the damage to the vehicle body caused by hail and other factors.
[0027] Furthermore, an inner partition 15 is installed inside the inflatable airbag 11, and two connecting pipes 14 are connected to the outside of the inflatable airbag 11, with each connecting pipe 14 installed on the upper and lower sides of the inner partition 15 respectively.
[0028] Furthermore, the top surface of the car cover body 1 is equipped with two sets of air inlets 5, and each set of air inlets 5 has two air inlets 5. The two air inlets 5 in each set are connected to the corresponding connecting pipe 14, and the openings of the two sets of air inlets 5 face opposite directions.
[0029] It should be noted that the air inlet 5 can be connected to the vehicle air pump, and the air inlet 5 has a built-in anti-leakage function. This is a mature existing technology and will not be elaborated here. In addition, the opening orientation of the two sets of air inlets 5 is such that one set faces the inside of the car cover body 1 and the other set faces the outside of the car cover body 1, so that air can be injected inside or outside the car according to actual needs.
[0030] Furthermore, a set of air inlets 5 with inward openings are installed on the top surface of the car cover body 1 and the air inlets 5 extend to the area near the driver's side window, so that the driver can inflate or deflate the two-layer inflation area of the airbag 11 inside the car cover body 1 by opening the car window from inside the car. A set of air inlets 5 with outward openings are installed on the hood area of the top surface of the car cover body 1, so that the user can place the air pump on the hood to inflate or deflate the two-layer inflation area of the airbag 11 inside the car cover body 1.
[0031] Furthermore, each of the two air inlets 5 in each group is connected to the corresponding connecting pipe 14, that is, each connecting pipe 14 is connected to two connecting pipes on the outside, and the two ends of each connecting pipe are connected to two air inlets 5 with openings facing the inside and outside of the car cover body 1, respectively.
[0032] Furthermore, the inner partition 15 can separate the inflatable airbag 11 into upper and lower layers, improving protection and stability. The upper and lower layers form a double buffer, enhancing the impact resistance.
[0033] Furthermore, multiple fixing straps 3 are installed on both outer sides of the car cover body 1, and each fixing strap 3 has a hook 4 at its bottom end to improve the stability of the car cover body 1 installed on the car body.
[0034] This utility model provides a three-layer inflatable car cover. The specific working principle is as follows: First, unfold the main body 1 of the car cover and cover the car body, so that the first connecting seam 2 is aligned with the driver and passenger door positions, the second connecting seam 7 is fitted on the outside of the rearview mirror, and the semi-enclosed cover 8 naturally wraps around the rearview mirror.
[0035] Subsequently, the car cover body 1 is initially secured by hooking the hook 4 at the bottom of the fixed strap 3 to the fixed point at the bottom of the vehicle, preventing it from shifting before inflation.
[0036] At this time, the person can open the car cover body 1 through the first connecting seam 2 and enter the car. At this time, the opening of the air inlet 5 faces the inside of the car cover body 1. Then the vehicle-mounted air pump can be connected to the corresponding air inlet 5, or the air inlet 5 in the engine hood area on the outside of the car cover body 1 can be selected for inflation according to actual needs. Start the air pump to inflate the airbag 11.
[0037] Gas enters the cavities on the upper and lower sides of the inner partition 15 through the connecting pipe 14, and the inner partition 15 divides the inflatable airbag 11 into upper and lower layers.
[0038] As the gas fills in, the airbag 11 gradually expands, the outer upper Oxford cloth layer 9 and the first PVC layer 10 are stretched, and the inner second PVC layer 12 and the lower Oxford cloth layer 13 fit the vehicle body to form a three-layer protective structure.
[0039] After inflation, the air inlet 5 closes automatically to prevent air leakage. The upper and lower layers of the inflatable airbag 11 form a double buffer space. When encountering impacts such as hail, the upper inflation chamber first absorbs part of the impact force, and the remaining force is transmitted to the lower chamber through the inner partition 15. After being buffered again, it is transmitted to the vehicle body, greatly reducing damage. At the same time, the rain guard 6 forms a shield at the first connecting seam 2, reducing the seepage of rainwater and hail from the first connecting seam 2.
[0040] If you need to use the vehicle, simply unhook the hook 4 and deflate the two inflatable areas inside the airbag 11 through the air inlet 5. After deflation, simply put the car cover away. The semi-enclosed cover 8 enhances the support through sewing stitching, and keeps the rearview mirror stably wrapped in the inflated state to prevent the rearview mirror from being damaged by impact.
[0041] 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.
