Description

Technical Field

[0001] The utility model relates to the technical field of car covers, in particular to a car cover with an air guide groove structure. Background Art

[0002] Car cover, also known as car film, is a thin film installed on the car. It mainly belongs to the beauty or modification projects in the automotive aftermarket. The basic functions include personalized decoration, paint protection and easy scrubbing. There are many types of car covers to choose from. The entire vehicle surface can be covered without splicing. The seams perfectly show the streamlined shape of the vehicle body. While beautifying the appearance of the vehicle, it also plays a role in protecting the paint, preventing the paint from oxidation and damage, and protecting the gloss and durability of the original paint.

[0003] During the installation process of traditional car covers or films, especially when they are attached to the vehicle surface, it is often difficult to avoid the generation of bubbles. These bubbles not only affect the aesthetics of the car cover or film, but may also weaken the adhesion between the film and the vehicle body due to long-term existence, and even cause premature shedding or damage to the film.

[0004] When installers try to remove these bubbles, they usually need to spend more time and energy using various tools such as scrapers and heat guns to try to drive out the bubbles or make them disappear. However, this method is not only inefficient, but may also cause unnecessary damage to the car cover or film as well as the vehicle surface. In addition, even if the bubbles are successfully expelled during the initial installation, they may still reappear during subsequent use due to factors such as temperature changes and vehicle vibrations. Therefore, existing car covers have obvious deficiencies in removing bubbles and maintaining fit.

[0005] In view of this, this application is hereby filed. Utility Model Content

[0006] The purpose of the present invention is to provide a car cover with an air guide groove structure to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the utility model provides a car cover with an air guide groove structure, including a base film, a film and a protective film. The central area of ​​the side wall of the film away from the base film is provided with a plurality of protrusions distributed in a rectangular array, and the side wall of the film away from the base film is provided with a limit strip 1 on both sides opposite to each other. The length direction of the limit strip 1 is consistent with the length direction of the film. The two limit strips are provided with the same limit strip 2 at one end close to each other on the same side, and the limit strip 2 does not contact the protrusions.

[0008] Furthermore, there is a gap between two adjacent protrusions, and positioning blocks are provided at equal intervals on the edge of the side wall of the film away from the base film. The first limiting strip is located between the protrusion and the positioning block, and the second limiting strip is located between the protrusion and the positioning block.

[0009] Furthermore, the side wall of the second limiting strip away from the protrusion is wavy, the side wall of the second limiting strip close to the protrusion is an inclined surface, and the side wall of the second limiting strip close to the protrusion is inclined from the center of the side wall toward the two ends of the second limiting strip.

[0010] Furthermore, the two limiting strips 1 are symmetrically arranged about the central axis of a side wall of the film away from the base film, the cross section of the limiting strip 1 is wavy, and the ends of the limiting strip 1 and the limiting strip 2 close to each other are arranged toward the corner of the film.

[0011] Furthermore, the base film is arranged on a side wall of the film away from the bump, and a protective film is arranged on a side wall of the base film away from the film.

[0012] Furthermore, an optical coating is applied on one side wall of the film and the base film that are close to each other.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. By setting structures such as bumps and limit strips on the film to form air guide grooves, the bubbles generated during the film application process can be guided to be quickly discharged along the formed path, thereby greatly improving the efficiency of bubble removal. This not only reduces the workload and time cost of the installers, but also reduces the risk of damage to the car cover or film and the vehicle surface due to improper bubble removal.

[0015] 2. The introduction of structures such as bumps and limit strips simplifies the installation process of car covers or car films, allowing installers to complete the film application work more easily. This not only improves work efficiency, but also reduces the technical difficulty of the installation process, allowing more consumers to complete the film application operation by themselves.

[0016] 3. Due to the certain thickness of structures such as bumps and limit strips, combined with the optical coating that can reflect ultraviolet rays, the direct sunlight on the vehicle surface can be reduced in outdoor areas with strong direct sunlight. At the same time, due to the distance between the film and the vehicle surface, the heat transferred from the film to the vehicle is also reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-3 The utility model provides a technical solution: it includes a base film 10, a thin film 11 and a protective film 12, and the central area of ​​the side wall of the thin film 11 away from the base film 10 is provided with a plurality of protrusions 20 distributed in a rectangular array, and the side wall of the thin film 11 away from the base film 10 is provided with limit strips 21 on both sides opposite thereto, and the length direction of the limit strip 21 is consistent with the length direction of the thin film 11, and the same limit strip 23 is provided at the end of the same side of the two limit strips 21 close to each other, and the limit strip 23 does not contact the protrusion 20.

[0025] It should be noted that: in a possible embodiment, the base film 10 and the film 11 are rectangular, and can also be shaped according to the corresponding vehicle model or cut and cut between them, wherein the material of the protrusion 20, the limiting strip 1 21, the positioning block 22 and the limiting strip 23 is the same as that of the film 11, which is PET, and the protrusion 20, the limiting strip 1 21, the positioning block 22 and the limiting strip 23 and the film 11 are all relatively flexible;

[0026] Furthermore, the gaps between adjacent bumps 20 can be regarded as protrusions of the film 11 itself. When applying the film, a hot air blower is used to blow the film so that the film 11 can better adhere to the surface of the vehicle body. When a scraper is used to smooth the protrusions, the gas in the film 11 will be more easily discharged along these grooves.

[0027] See also Figure 1-3The utility model provides a technical solution: there is a gap between two adjacent protrusions 20, and positioning blocks 22 are evenly spaced at the edge of the side wall of the film 11 away from the base film 10. The first limiting strip 21 is located between the protrusion 20 and the positioning block 22, and the second limiting strip 23 is located between the protrusion 20 and the positioning block 22.

[0028] It should be noted that the cross-section of the bumps 20 is diamond-shaped, and the gaps between two adjacent bumps 20 form an air guide groove structure, and a grid-shaped air guide groove network is formed between multiple adjacent bumps 20, so that bubbles generated during film application can be discharged along multiple paths;

[0029] The diamond-shaped protrusions 20 make the entire air guide groove network an oblique grid, which allows the film 11 to better adapt to the uneven areas of the car surface and has a stronger tensile strength.

[0030] See also Figure 1-3 The utility model provides a technical solution: the side wall of the second limit strip 23 away from the protrusion 20 is wavy, the side wall of the second limit strip 23 close to the protrusion 20 is an inclined surface, and the side wall of the second limit strip 23 close to the protrusion 20 is inclined from the center of the side wall toward the two ends of the second limit strip 23.

[0031] It should be noted that during the film application process, the car surface needs to be cleaned first, and then the surface of the film 11 needs to be moistened to ensure better adhesion between the film 11 and the car surface. Therefore, excess water will inevitably be generated during the application process. At this time, the water can be discharged along the air guide groove network.

[0032] In a possible embodiment, the present design is used to apply film to the hood of a vehicle, where the second limiting strip 23 corresponds to the front end of the vehicle, that is, when attached, the second limiting strip 23 is attached with its back to the windshield. Then, when excess water is discharged, the double inclined surface of the side wall of the second limiting strip 23 close to the protrusion 20 causes the water to flow along the second limiting strip 23 to the two corners of the film 11, thereby preventing water from flowing into the heat dissipation network at the front end of the vehicle.

[0033] See also Figure 1-3 The utility model provides a technical solution: the two limit strips 21 are symmetrically arranged about the central axis of the side wall of the film 11 away from the base film 10, the cross-section of the limit strip 21 is wavy, and the end of the limit strip 21 and the limit strip 2 23 that are close to each other is arranged toward the corner of the film 11.

[0034] It should be noted that the limiting strip 21 is used to protect and fix the side wall of the film 11. At the same time, the wavy structure of the limiting strip 21 allows it to withstand a certain amount of stretching and deformation, and the end bends toward the corner of the film 11 to further guide excess water.

[0035] See also Figure 1-3 The utility model provides a technical solution: the base film 10 is arranged on a side wall of the film 11 away from the bump 20 , and a protective film 12 is provided on a side wall of the base film 10 away from the film 11 .

[0036] It should be noted that the protective film 12 is the layer farthest from the vehicle surface compared to the base film 10 and the film 11, that is, it is located in the outermost layer, and is used to protect the base film 10 and the film 11 from damage. In a possible implementation, the protective film 12 is made of TPU material. Due to the elastic properties of TPU, it can effectively resist scratches and wear caused by daily use. Minor scratches on the TPU material can often be automatically repaired and restored to their original state.

[0037] See also Figure 1-3 The present invention provides a technical solution: an optical coating is applied on one side wall of the film 11 and the base film 10 which are close to each other.

[0038] It should be noted that the optical coating is used to reflect ultraviolet rays to reduce the heat caused by direct ultraviolet rays to the vehicle itself. In a possible embodiment, the optical coating is made of silicon dioxide.

[0039] Working principle:

[0040] The gap between two adjacent protrusions 20 forms an air guide groove structure, and a grid-shaped air guide groove network is formed between adjacent protrusions 20, so that bubbles generated during film application can be discharged along multiple paths. The first limiting strip 21 is used to protect and fix the side wall of the film 11. At the same time, the wavy structure of the first limiting strip 21 and the second limiting strip 23 allows them to withstand a certain amount of stretching and deformation. The ends are bent toward the corners of the film 11 to further guide excess water.

[0041] During mounting, according to conventional film-mounting methods, a hot air blower is used to blow the film to make it fit the surface of the vehicle body more closely, while a scraper is used to assist in pressing it. Air can more easily flow through the air guide grooves formed by the multiple bumps 20 and then be discharged. At the same time, the bumps 20 will also be softened by heat and attached to the surface of the vehicle body. When the scraper is used to flatten the exhaust, the air remaining between the multiple bumps 20 is also discharged.
