Description

Technical Field

[0001] This utility model relates to car covers, and more specifically, to segmented easy-apply car covers. Background Technology

[0002] Paint protection film (PPF) is a thin film used to protect car bodies, isolating the paint from the air and providing long-lasting protection. After application, it protects the paint from acid rain, oxidation, and scratches. It generally consists of a base layer, an adhesive layer, and a release layer. The release layer adheres to the adhesive layer to prevent contamination and can be easily separated. The adhesive layer secures the PPF to the painted areas of the car, typically including the hood, front bumper, rear bumper, doors, roof, trunk, side skirts, front and rear fenders, and A / B pillars. The base layer uses a strong, durable material for puncture and scratch resistance. While PPF can be applied manually after initial application, this method can damage the paint. Therefore, depending on the car model, PPF can also be computer-cut to fit the specific vehicle. However, when applying to larger areas like the hood, doors, and trunk, the large area makes alignment difficult, potentially requiring repeated stretching and application, which can affect adhesion and make the application inconvenient.

[0003] Chinese Patent Publication No. CN219689633U discloses a corrosion-resistant car cover. The key technical points of this solution are: it includes a base layer, an adhesive layer, and a release layer. The release layer consists of two release films. An adhesive strip is provided along the edge of the lower surface of one release film near the other, and the adhesive strip covers the surface. This invention uses the adhesive strip for pre-fixation of the car cover. The adhesive strip is discarded after peeling off the release layer. Even if the car cover is not ideally positioned during fixing, multiple attempts can be made without affecting the adhesive bonding effect. When applying the car cover to large areas such as the hood, doors, and trunk, the alignment process is simpler, making the application more convenient.

[0004] When applying film to large areas such as the hood and trunk, even though the car wrap has a positioning adhesive strip in the middle, it is easy to wrinkle during the application process when only half of the car wrap is applied and the release film is removed. This is because half of the car wrap is still quite large.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a segmented and easy-to-apply car cover.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a segmented easy-to-apply car wrap, including a base layer, an adhesive layer and a release layer, wherein the release layer is divided into several release films, and an adhesive strip is provided on the release film near the middle, and the adhesive strip is covered by the release strip.

[0008] The present invention is further configured such that all release films located on the same side of the adhesive strip are connected and fixed by a dot-shaped connection structure.

[0009] The present invention is further configured such that: the dotted connection structure is a connection point with a width of less than 1 cm, and the connection point connects two adjacent release films.

[0010] The present invention is further configured such that the connection point is located at one corner of the release film.

[0011] The present invention is further configured such that a self-healing layer is provided on the base layer.

[0012] The present invention is further configured such that the self-healing layer is a fluorocarbon self-healing coating.

[0013] In summary, this utility model has the following beneficial effects: The car cover is pre-fixed using adhesive strips. If the car cover is not positioned ideally during fixing, it can be re-fixed by tearing off the adhesive strips multiple times without affecting the adhesive layer's bonding effect. After the adhesive strips are pre-positioned, the release film near the adhesive strips is peeled off, exposing a portion of the adhesive layer. The car cover is then fixed to the car body using the adhesive layer, thus completing part of the car cover's fixation. Then, different release films are peeled off one by one for segmented application. Because there are multiple release films, after peeling off one, the adhesive layer can be immediately applied to the car, avoiding wrinkles caused by the car cover's large area. The adhesive layer can also be applied immediately, preventing dust and impurities from the environment from adhering to the adhesive layer, thus improving the film application quality. The adhesive strips are discarded after being peeled off with the release layers. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0020] Segmented easy-to-apply car wrap, such as Figure 1-3 As shown, the car cover includes a base layer 1, an adhesive layer 2, and a release layer. The base layer 1 is a TPU layer, which has high light transmittance, good softness, high resilience, strong tensile strength, and a tough texture. This allows the car cover to show the original paint color of the vehicle. It is soft and easy to stretch, making it convenient to apply to the car. Its tough texture also provides excellent puncture and scratch resistance. A self-healing layer 7 is provided on the base layer 1. This self-healing layer 7 repairs minor scratches (≤3μm) at room temperature or after heating, maintaining the surface smoothness of the car cover. The high density of the self-healing layer 7 reduces the penetration of corrosive substances such as acid rain and tree sap, protecting the paint. The self-healing function of the self-healing layer 7 extends the lifespan of the car cover from 5 years to 8-10 years. The self-healing layer 7 is a fluorocarbon self-healing coating. The fluorocarbon coating can complete scratch repair within 30 minutes at room temperature (traditional TPU requires more than 60 minutes). Its coating uses fluororesin as the main film-forming substance, which has a certain scratch self-healing ability. Due to the high electronegativity of the introduced fluorine element and the strong carbon-fluorine bond energy, it has particularly superior properties. Its weather resistance, heat resistance, low temperature resistance and corrosion resistance are all excellent. Moreover, it has unique non-stick and low friction properties, which allows the car cover to prevent the corrosion of stains such as acid rain, insect remains, tar, and tree sap. The fluorocarbon self-healing coating also has extremely low surface energy, and surface dust can be self-cleaned by rainwater, without sticking to dust and accumulating dirt, and has good anti-fouling properties.

[0021] like Figure 1-3 As shown, the release layer consists of several release films 3. An adhesive strip 4 is located on the release film 3 near the center. The adhesive strip 4 is covered by a release strip 5. After tearing off the release strip 5, the car cover is pre-fixed using the adhesive strip 4. If the car cover is not positioned ideally during fixing, it can be re-attached multiple times by tearing off the adhesive strip 4 without affecting the adhesion of the adhesive layer 2. After the adhesive strip 4 is pre-positioned, the release film 3 near the adhesive strip 4 is peeled off, exposing a portion of the adhesive layer 2. The car cover is then fixed to the car body using the adhesive layer 2, thus completing part of the car cover's fixation. Then, different release films 3 are peeled off one by one outwards for segmented application. Because there are many release films 3, after peeling off one, the adhesive layer 2 can be immediately applied to the car, avoiding wrinkles caused by the large area of ​​the car cover. This also ensures the adhesive layer 2 is applied immediately, preventing dust and impurities from adhering to it, thus improving the quality of the application. The adhesive strip 4 is discarded after being peeled off with the release layer.

[0022] like Figure 1 and Figure 4As shown, all release films 3 located on the same side of the adhesive strip 4 are connected and fixed by a dot-shaped connection structure. The dot-shaped connection structure can provide operational continuity and maintain a weak correlation between the release films 3. This avoids scattering and facilitates step-by-step operation as needed. After completely separating one release film 3, the next one that needs to be torn off is picked up by the dot-shaped connection structure. There is no need to peel it off with your fingers from the edge. This simplifies the operation and improves the efficiency of applying car wrap. It can separate the release films 3 one by one and prevent the adhesive layer 2 from being accidentally exposed when multiple release films 3 are torn off at once. Furthermore, the dotted connection structure is a connection point 6 with a width of less than 1cm. In this embodiment, a connection point 6 of 0.5cm is used. The connection point 6 connects two adjacent release films 3. The two adjacent release films 3 are not completely cut apart. The remaining part of the connection structure forms the connection point 6. The narrower connection point 6 (such as 0.5cm) can be torn open with less external force, reducing the intensity of operation. Moreover, the connection point 6 only occupies the corner of the release film 3. When tearing open the release film 3, it is easy to control the corner part to be torn open last. By tearing the connection point 6 in the corner last, it is easy to avoid tearing open the next release film 3 along with it, avoiding contamination caused by exposure of the adhesive layer 2. In addition, the connection point 6 in the corner is convenient for technicians to operate. The release film 3 can be pinched and torn open with one hand. The uniform position of the connection point 6 forms an operating habit, which can reduce the probability of accidental tearing. In addition, the corner connection avoids the tensile stress on the main area of ​​the adhesive layer 2, preventing the edge from lifting when applying the film.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
