Description

Technical Field

[0001] The utility model relates to the technical field of protective film structures, in particular to a flat touch screen protective film. Background Art

[0002] According to the purpose, protective films can be divided into digital product protective films, car protective films, household protective films, food preservation protective films, etc. With the popularity of digital products such as mobile phones in China, protective films have gradually become a general term for screen protective films.

[0003] The popularity of touch screens has led to an increasing demand for protective films, so touch screen protective films play an important role. In the existing technology, the touch screen protective film is used to operate the touch screen on the protective film and can also protect the touch screen.

[0004] However, the four sides of the flat touch screen protective film in the prior art are vertical surfaces except the upper and lower surfaces. The vertical surfaces are subjected to large forces when colliding with external structures. The forces acting on the surface of the protective film are not easy to disperse, which can easily cause the corners of the protective film to warp up or separate on the flat touch screen, affecting the normal use of the protective film.

[0005] For this reason, we propose a flat touch screen protective film to solve the existing problems. Utility Model Content

[0006] The utility model aims to provide a flat touch screen protective film in view of the problems existing in the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flat touch screen protective film, comprising an upper separation protective film, a protective film body, a lower separation protective film and an adsorption silicone film, the lower surface of the protective film body being adhered to the lower separation protective film, the upper surface of the protective film body being adhered to the upper separation protective film, and the four sides of the protective film body being designed to be arc-shaped.

[0008] Preferably, the shape of the upper separation protective film is adapted to the shape of the protective film body;

[0009] An upper hand-tear label is provided at the end of the outer wall of the upper separation protective film;

[0010] A lower hand-tear label is arranged at the outer wall end of the lower separation protective film.

[0011] Preferably, the protective film body is divided into three layers: an AG hardening layer, an HC treatment layer and a PET substrate.

[0012] Preferably, an adsorption silica gel film is provided on the lower surface of the protective film body.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. During the use of the flat touch screen protective film of the utility model, the four sides of the protective film body are designed to be arc-shaped. When the arc-shaped surface collides with the external structure, the force acting on the surface of the protective film can be reduced, and the force acting on the surface of the protective film can be easily dispersed, so as to avoid the corners of the protective film from being lifted up or separated on the flat touch screen, thereby ensuring the normal use of the protective film.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] like Figure 1-Figure 3 As shown, the utility model proposes a flat touch screen protective film, comprising an upper separation protective film 1, a protective film body 2, a lower separation protective film 3 and an adsorption silicone film 204, the lower surface of the protective film body 2 is adhered with the lower separation protective film 3, the upper surface of the protective film body 2 is adhered with the upper separation protective film 1, and the four sides of the protective film body 2 are designed to be arc-shaped.

[0023] Based on Example 1:

[0024] The protective film can be glued to the flat touch screen by adsorption of the silicone film 204. The four sides of the protective film body 2 are designed to be arc-shaped. When the arc-shaped surface collides with the external structure, the force acting on the surface of the protective film can be reduced, and the force acting on the surface of the protective film can be easily dispersed, thereby avoiding the corners of the protective film from warping up and separating on the flat touch screen, thereby ensuring the normal use of the protective film.

[0025] Embodiment 2

[0026] like Figure 1-Figure 3 As shown, the utility model proposes a flat touch screen protective film. Compared with the first embodiment, this embodiment also includes: the shape of the upper separation protective film 1 is adapted to the shape of the protective film body 2; through the design of the upper separation protective film 1 and the lower separation protective film 3, both sides of the protective film body 2 can be protected.

[0027] An upper hand-tear label 4 is provided at the end of the outer wall of the upper separation protection film 1;

[0028] A lower tear-off label 5 is provided at the end of the outer wall of the lower separation protective film 3 . The design of the tear-off label facilitates the peeling of the upper separation protective film 1 and the lower separation protective film 3 from the protective film body 2 .

[0029] The protective film body 2 is divided into three layers: an AG hardening layer 201, an HC treatment layer 202 and a PET substrate 203;

[0030] The AG hardening layer 201 makes the touch screen protective film more wear-resistant and drop-resistant, thereby improving the practicality of the touch screen protective film.

[0031] The HC treatment layer 202 makes the touch screen protective film have good light transmittance, good wear resistance and suitable adsorption capacity.

[0032] The PET substrate 203 makes the touch screen protective film wear-resistant, scratch-resistant, yellowing-resistant, pressure-resistant, high-temperature-resistant, etc., and the performance in all aspects is very stable.

[0033] The lower surface of the protective film body 2 is provided with an adsorption silicone film 204, and the protective film can be adsorbed and glued on the flat touch screen through the adsorption silicone film 204. The adsorption silicone film 204 is a thin film material with adsorption ability, mainly made of silicone.

[0034] The adsorption performance of the self-adsorption silica gel film 204 is one of its most important characteristics. It can be adsorbed on various surfaces, such as glass, metal, plastic, etc., to form a stable adsorption layer. This adsorption layer has strong adhesion and can effectively fix objects and prevent them from sliding or falling off.

[0035] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
