Description

Technical Field

[0001] The utility model relates to a protective film technology, in particular to a protective film of a vehicle-mounted touch screen and a material strip thereof. Background Art

[0002] As the automobile market grows, the amount of in-vehicle displays and in-vehicle touch screens also increases, with more and more various appearances and shapes, and the requirements for the in-vehicle touch screens are also getting higher and higher.

[0003] At present, when the vehicle-mounted touch screen is shipped, a protective film is attached to the front. In order to facilitate the subsequent tearing of the film, the protective film has a tearing handle, and the tearing handle extends to the outside of the vehicle-mounted touch screen for easy grabbing by hand. When the car factory assembles the whole vehicle, the tearing handle extending from the protective film will interfere with the vehicle display screen and casing near the vehicle-mounted touch screen. Therefore, before assembling the vehicle-mounted touch screen into the whole vehicle, the car factory will tear off the protective film on the vehicle-mounted touch screen, and after assembling the vehicle-mounted touch screen into the whole vehicle, a new protective film will be re-attached. The new protective film is finally torn off by the consumer after the whole vehicle is sold.

[0004] The vehicle-mounted touch screen uses two protective films before and after the whole vehicle is assembled, resulting in material waste and cost increase. Utility Model Content

[0005] In order to solve the above-mentioned deficiencies of the prior art, the utility model provides a protective film, which can realize the film-attached assembly of the vehicle-mounted touch screen during the assembly of the whole vehicle, so as to avoid material waste and reduce costs.

[0006] The utility model also provides a material strip, comprising the above-mentioned protective film.

[0014] Furthermore, an adhesive layer is provided on one side surface of the protective film, and the adhesive layer covers the primary protective area and the secondary protective area and avoids the primary film tearing handle and the secondary film tearing handle.

[0015] Furthermore, a handle gap is opened on one side of the main protective area, and the main film tearing handle is arranged in the handle gap of the main protective area; the main film tearing handle has a connecting side, and the connecting side of the main film tearing handle is connected to the main protective area, and there is a gap between the two sides of the main film tearing handle adjacent to the connecting side and the main protective area.

[0016] Furthermore, the other side of the main film tearing handle relative to the connecting side is flush with the edge of the main protection area.

[0017] Furthermore, the main film tearing handle is located on a first side of the main protective area, and the secondary film tearing handle is located on a second side of the secondary protective area, and the first side and the second side are opposite sides of the protective film.

[0018] Furthermore, a handle mark is provided on the main film tearing handle.

[0019] Furthermore, the tearable structure is a breakpoint-type dividing line.

[0020] A material tape comprises a release film and a plurality of the above-mentioned protective films, wherein the plurality of protective films are arranged on the same side surface of the release film.

[0021] Furthermore, the material strip also includes a winding core, the release film is wound outside the winding core, and its side surface opposite to the multiple protective films faces the winding core; the multiple protective films are arranged in sequence along the winding direction of the release film.

[0022] Furthermore, the winding core is a hollow winding core.

[0023] The utility model has the following beneficial effects: the protective film of the utility model divides the entire protection area into the main protection area and the secondary protection area, the main protection area corresponds to the assembly exposed area of ​​the vehicle-mounted touch screen, and the secondary protection area corresponds to the assembly embedded area of ​​the vehicle-mounted touch screen. After the protective film is attached to the front of the vehicle-mounted touch screen, the main film-tearing handle is located within the range of the vehicle-mounted touch screen, and the secondary film-tearing handle is located outside the range of the vehicle-mounted touch screen; when the whole vehicle is assembled, the secondary protection area is first torn off from the vehicle-mounted touch screen through the secondary film-tearing handle to expose the The main protection area is disconnected from the secondary protection area and continues to remain on the exposed assembly area of ​​the vehicle touch screen to protect the exposed assembly area. The vehicle touch screen is directly assembled with the film. At this time, the main film-tearing handle is located within the range of the vehicle touch screen and will not interfere with the vehicle display screen and casing. Finally, after purchasing the vehicle, the consumer can tear off the main protection area from the vehicle touch screen through the main film-tearing handle, so that the vehicle touch screen only needs one protective film before and after the vehicle is assembled, which avoids material waste and reduces costs.
