The gloss of the first pressing portion 110 may be the same or different from the gloss of the second pressing portion 120.

Gloss is an optical property that exhibits the ability of an object to reflect light. It is usually expressed in units of 0-100 Gloss Unit (GU), which defines the reflectance of a standard black sheet as 100 gloss units. In the present embodiment, the gloss of the first pressing portion 110 is greater than the gloss of the surrounding portion 130, and the gloss of the second pressing portion 120 is greater than the gloss of the surrounding portion 130. More specifically, the first pressing portion 110 has a gloss of between 95 gloss units and 100 gloss units. In other words, the roughness of the first pressing portion 110 is smaller than the roughness of the surrounding portion 130, and the roughness of the second pressing portion 120 is smaller than the roughness of the surrounding portion 130, so that the first pressing portion 110 and the second pressing portion 120 are The touch is more detailed than the surrounding portion 130 to provide a good hand.

In addition, as can be seen from FIG. 3, the upper surface of the first pressing portion 110 of the protective film 100 has the convex structure 114, but the lower surface is flat. This design is because the protective film 100 of the silicone material has a tolerance after molding. Large, mass production is not easy to require precision, and the first pressing portion 110 of the protective film 100 also has a registration tolerance after being assembled in the first input region 14 (keyboard). In order to make the assembly convenient and the user not to perceive the tolerance when typing, the protective film 100 of the present embodiment is presented in a planar manner on the lower surface of the first pressing portion 110, instead of the lower surface of the conventional protective cover. Conforms to the outline of the button.

In addition, in general, the second body 12 has a step difference between the second input area 15 (ie, the touch panel) and the surrounding area 16 (that is, the plane beside the touch panel), more specifically, the second The input area 15 will be lower than the surrounding area 16. The protective film 100 of the present embodiment also has a corresponding arrangement in the second pressing portion 120 and the peripheral portion 130. Figure 4 is a schematic cross-sectional view taken along line A-A of Figure 2; 2 and FIG. 4, the thickness of the second pressing portion 120 of the protective film 100 of the present embodiment is different from the thickness of the surrounding portion 130. More specifically, the thickness of the second pressing portion 120 is greater than the thickness of the surrounding portion 130, and the upper surface of the second pressing portion 120 is coplanar with the upper surface of the surrounding portion 130. In other words, the lower surface of the second pressing portion 120 may be lower than the lower surface of the surrounding portion 130 to accommodate the contour of the second input region 15 of the second body 12 and the surrounding region 16. In addition, there is a lead angle at the intersection of the second pressing portion 120 and the surrounding portion 130 to facilitate application of the adhesive layer.

It is worth mentioning that the hinge of the conventional notebook computer will be located next to the second body or obliquely above. Therefore, the side of the conventional second body will have components connected to the rotating shaft near the upper surface, and the use The waterproof and dustproof protective film is blocked by this component and cannot completely cover the entire electronic device surface of the second body. However, if the surface of the electronic device is not completely covered, liquid or dust may enter from the edge.

FIG. 5 is a partial cross-sectional view of the electronic device of FIG. 1. FIG. Referring to FIG. 5, in the embodiment, the rotating shaft 17 is recessed on the side of the second body 12, that is, the rotating shaft 17 is located below the surface 13 of the electronic device, and the projection of the rotating shaft 17 on the plane of the surface 13 of the electronic device overlaps. On the surface 13 of the electronic device. In this way, because the space beside the second body 12 is released, the protective film 100 can cover the entire electronic device surface 13 and then press through the fixing frame 18 to press the protective film 100 and the second body 12 close to the electronic device. The periphery of the surface 13 prevents the protective film 100 from being accidentally turned up by the user.

In addition, referring back to FIG. 1, in the present embodiment, since the convex structure 114 of the protective film 100 is only 0.05 mm to 0.55 mm higher than the surrounding portion 130, the height of the button is higher than that of a general notebook computer. 1.3 to 1.5 mm is much less, and therefore, the upper surface of the protective film 100 is relatively flat, and can be regarded as a temporary table to use the mouse. As shown in FIG. 1, the mouse can operate on the first pressing portion 110 and the second pressing portion 120, and is not limited to the peripheral portion 130. That is to say, the protective film 100 of the present embodiment can also allow the entire protective film 100 to be used as a general desktop on the premise that the user can clearly know the position of the button 19 and provide a comfortable typing feeling.

In summary, the protective film created by the present invention includes a first pressing portion for covering a first input area (such as a keyboard) on the surface of the electronic device and a surrounding area for covering the surface of the electronic device (for example, a keyboard) The surrounding part of the plane). The gloss of the first pressing portion is different from the gloss of the surrounding portion, for example, the gloss of the first pressing portion is greater than the gloss of the surrounding portion, in other words, the roughness of the first pressing portion is smaller than the roughness of the surrounding portion, so that The touch of the first pressing portion is finer to provide a good hand. In addition, the first pressing portion includes a plurality of convex structures corresponding to the keys of the keyboard, and the thickness of each convex structure at the edge is greater than the thickness of the center, and the upper surface of each convex structure is concavely curved for convenient use.
