[0001] The utility model relates to a car covering film, more specifically, to a covering film for a special-shaped cover plate on a vehicle. Background Art
[0002] As there are more and more special-shaped covers on vehicles, the roller-mounted optical film is prone to deviation due to the existence of different 3D planes. With the gradual rise of new energy electric vehicles, various high-tech products are being used in new energy vehicles, including smart cockpits. New energy vehicles will gradually popularize dual-screen or triple-screen human-computer interaction systems, and will gradually switch from the current flat cover glass to more beautiful curved glass. Attaching optical film to curved glass cover is a must for many high-end models. Optical film can reduce the reflectivity from the glass surface and improve the driver's satisfaction. At the same time, optical film can prevent the risk of the car bursting during a collision and improve the safety factor of the car. However, the difficulty is that it is difficult to attach optical film to curved glass, and the application efficiency is low.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0029] As described in the background technology, for electric vehicles, the existing technology is prone to deviation when the roller is pasted with optical film due to the increasing number of special-shaped cover plates on the vehicle and the existence of different 3D planes. With the gradual rise of new energy electric vehicles, various high-tech products are being used in new energy vehicles, including smart driving cabins. New energy vehicles will gradually popularize the human-computer interaction system of dual screens or triple screens, and will gradually switch from the current flat cover glass to more beautiful curved glass. Attaching an optical film to a curved glass cover is a must for many high-end models. The optical film can reduce the reflectivity from the glass surface and improve the driver's satisfaction. At the same time, the optical film can prevent the risk of the car bursting during a collision and improve the safety factor of the car. However, the difficulty is that it is difficult to attach an optical film to curved glass, and the application efficiency is low.
[0030] In order to solve this technical problem, the utility model provides an application film for a vehicle-mounted special-shaped cover plate, comprising a release film layer 1, an optical film layer 2 is provided on the upper surface of the release film layer 1, a protective film layer 3 is provided on the upper surface of the optical film layer 2, and an alignment area P is provided on the protective film layer 3. A first alignment line 31 is provided on the alignment area P, and the first alignment line 31 extends along the length direction of the protective film layer 3.
[0031] Through the above-mentioned structural design, on the protective film 3, the starting position when the bonding surface is a plane, that is, the plane area S1 is used as the starting position, and the bonding operation is performed with reference to the first alignment line 31. The specific process is: first grab the mark on the protective film layer 3, that is, the first alignment line 31, and then use the automated equipment to roller-bond the plane area S1 first, so that the position and accuracy of the optical film layer 2 can be guaranteed by the equipment. When the plane area S1 is bonded, the positions of the curved areas S2 on both sides will naturally be suspended. At this time, the bonding of the curved area S2 is completed by manual roller bonding, thereby completing the bonding of the optical film of the entire vehicle-mounted special-shaped cover plate S. Since the first alignment line 31 is set as a reference line, the combination of equipment bonding and manual bonding effectively improves the bonding accuracy and efficiency of the optical film of the vehicle-mounted special-shaped cover plate, thereby improving the driver's satisfaction and the safety factor of the car.
[0032] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0040] On the protective film 3, the starting position when the bonding surface is a plane, that is, the plane area S1 is used as the starting position, and the bonding operation is performed with reference to the first alignment line 31. The specific process is: first grab the mark on the protective film layer 3, that is, the first alignment line 31, and then use the automated equipment to roller-bond the plane area S1 first, so that the position and accuracy of the optical film layer 2 can be guaranteed by the equipment. When the plane area S1 is bonded, the positions of the curved areas S2 on both sides will naturally be suspended. At this time, the bonding of the curved area S2 is completed by manual roller bonding, thereby completing the bonding of the optical film of the entire vehicle-mounted special-shaped cover plate S. Since the first alignment line 31 is set as a reference line, the combination of equipment bonding and manual bonding effectively improves the bonding accuracy and efficiency of the optical film of the vehicle-mounted special-shaped cover plate, thereby improving the driver's satisfaction and the safety factor of the car.

Since a pair of second alignment lines 32 are provided, the lateral position of the optical film layer 2 can be accurately controlled, and the longitudinal position of the optical film layer 2 can also be accurately controlled, further improving the laminating accuracy and laminating efficiency of the optical film of the vehicle-mounted special-shaped cover.
[0045] like Figure 5 As shown, the application film of the vehicle-mounted special-shaped cover provided in Example 1 or 2 is further optimized. Specifically, a pair of cross-shaped contrast marks 33 are provided on the alignment area P.

[0049] When performing the optical film laminating operation, the automated equipment first grabs the mark on the protective film layer 3, namely the comparison mark 33, and then uses the automated equipment to roll the flat area S1 first. In this way, the position and accuracy of the optical film layer 2 can be guaranteed by the equipment. Since a pair of comparison marks 33 are set, the lateral position and longitudinal position of the optical film layer 2 can be accurately controlled, and the laminating angle of the optical film layer 2 can also be detected in real time. The positioning center point 332 can assist the automated equipment in rapid positioning,
