Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive cover technology, specifically a wear-resistant automotive cover. Background Technology
[0002] With the development of technology, social progress, and improved living standards, cars have become an indispensable part of life. As more and more households own cars, the issue of vehicle storage arises. Due to the high cost of land, many car owners cannot afford garages, resulting in a large number of cars being stored in open areas. Car covers have thus emerged as a solution. As an excellent car protection product, car covers are made of soft materials according to the car's dimensions. They effectively protect the paint, extending its lifespan, and prevent insects, bird droppings, dust, and fallen leaves. In summer, when parked in an open area, they also protect the car from direct sunlight and damage caused by cold weather. However, existing car covers generally have a sun-protective coating, but this coating can be damaged by wear and tear, causing the cover to lose its original function. Utility Model Content
[0003] The purpose of this invention is to provide a wear-resistant car cover to solve the above-mentioned technical problems.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant car cover, comprising a cover body, the cover body comprising a self-healing layer, an ultraviolet-proof layer, a waterproof layer, a heat dissipation layer and a bottom cover, wherein the self-healing layer, ultraviolet-proof layer, waterproof layer, heat dissipation layer and bottom cover are arranged sequentially from top to bottom, the self-healing layer is a polyurethane coating containing chitosan and oxobutane structures, and the bottom cover is polyester fiber.
[0005] Preferably, the self-healing layer and the UV-protective layer are tightly bonded together.
[0006] Preferably, the heat dissipation layer includes heat dissipation holes and heat-conducting blocks.
[0007] Preferably, the front end of the vehicle cover body is provided with a reflective strip.
[0008] Preferably, a zipper is provided at the rear end of the car cover body.
[0009] Preferably, the zipper has pivots on both sides, and protective plates are connected to the pivots.
[0010] Preferably, a sealing ring is provided at the connection between the rotating shaft and the protective plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a self-healing layer, when the coating surface is scratched, the cyclic structure of oxetane in the self-healing layer breaks and can undergo a chemical reaction after exposure. When exposed to ultraviolet light, the chitosan in the coating and the exposed ends of oxetane attract each other and combine together to repair the cyclic structure, thereby realizing the self-repair of the coating damage, thus improving the wear resistance and practicality of the car cover.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4This utility model provides a technical solution: a wear-resistant car cover, including a cover body 1, the cover body 1 including a self-healing layer 2, an anti-ultraviolet layer 3, a waterproof layer 4, a heat dissipation layer 5 and a bottom cover 6, the self-healing layer 2, the anti-ultraviolet layer 3, the waterproof layer 4, the heat dissipation layer 5 and the bottom cover 6 are arranged sequentially from top to bottom, the self-healing layer 2 is a polyurethane coating containing chitosan and oxobutane structures, and the bottom cover 6 is polyester fiber.
[0021] Specifically, the self-healing layer 2 and the UV protection layer 3 are tightly bonded together. This tight bonding improves their fit and makes the self-healing layer 2 and the UV protection layer 3 more effective at absorbing ultraviolet rays.
[0022] Specifically, the heat dissipation layer 5 includes heat dissipation holes 7 and heat conduction blocks 8. By setting heat dissipation holes 7 and heat conduction blocks 8, the heat dissipation layer 5 can achieve better results.
[0023] Specifically, the front end of the car cover body 1 is provided with a reflective strip 9. By setting the reflective strip 9, the reflective strip 9 can reflect light, thereby serving as a warning and reducing the rate of scratches.
[0024] Specifically, a zipper 10 is provided at the rear end of the car cover body 1. Furthermore, pivots 11 are provided on both sides of the zipper 10, and protective plates 12 are connected to the pivots 11. Furthermore, a sealing ring 13 is provided at the connection between the pivots 11 and the protective plates 12. The protective plates 12 can rotate around the pivots 11, so that when the car cover is not in use, the protective plates 12 can cover the zipper 10 to prevent dust and moisture from entering the interior of the car cover. The sealing ring 13 ensures the sealing between the protective plates 12 and the car cover body 1, further improving the waterproof performance of the car cover. The setting of the protective plates 12 can also protect the zipper 10 from external damage and extend the service life of the car cover.
[0025] Working Principle: When in use, this wear-resistant car cover features a UV-protective layer 3 that absorbs ultraviolet rays, reducing material aging. A waterproof layer 4 prevents rainwater and other liquids from penetrating, protecting the car from moisture and corrosion. The heat dissipation layer 5, with its ventilation holes 7 and heat-conducting blocks 8, effectively dissipates heat from the inside of the cover, preventing excessively hot seats in summer. Reflective strips 9 provide a reflective surface, serving as a warning and reducing the risk of scratches. The combination of zippers 10 and protective panels 12 facilitates... Users can retrieve items from the trunk by unzipping 10. The protective plate 12 protects both the zipper 10 and the car cover body 1, enhancing the durability and protective capabilities of the car cover. When the self-healing layer 2 is scratched or worn, the cyclic structure of the oxetine in the self-healing layer 2 breaks. Upon exposure, a chemical reaction occurs. When exposed to ultraviolet light, the chitosan in the coating attracts and combines with the exposed ends of the oxetine to repair the cyclic structure, thereby achieving self-repair of the damaged area of the coating and further enhancing the wear resistance of the car cover.
