Detailed ways

Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

Please refer to FIG. 1, FIG. 2A and FIG. 2B, FIG. 1 is a schematic diagram of a portable electronic device according to an embodiment of the present invention, and FIG. 2A is a cross-section of the portable electronic device along the section line 2A-2A in FIG. 1 2B is a cross-sectional view when the protective film in FIG. 2A is removed from the key set.

As shown in FIG. 1 , the portable electronic device 10 includes a keyboard body 100 and a screen body 200 . The screen body 200 is, for example, coupled to the keyboard body 100 in a pivotal manner.

As shown in FIG. 2A and FIG. 2B , the keyboard body 100 includes a protective film 120 and a key set (described below). The protective film 120 includes a covering portion 121 and a fixing portion 122 . The fixing part 122 is connected around the covering part 121 and has a first locking part 122a. The key set includes a shell 111 and a plurality of keys 113 . The shell 111 includes a fixed shell 111a and a movable shell 111b. The movable shell 111b is detachably disposed on the fixed shell 111a, and has a plurality of through holes 111b1 (marked in FIG. 2B ) and a second engaging portion 111b2 (marked in FIG. 2B ).

In order to provide dustproof, waterproof and protective functions, the covering part 121 covers the buttons 113 . The buttons 113 are respectively exposed outside the movable casing 111b through the through holes 111b1 , and the cover portion 121 on the buttons 113 is also exposed outside the movable casing 111b through the through holes 111b1 . The first engaging portion 122a of the fixing portion 122 is engaged with the second engaging portion 111b2 to firmly fix the protective film 120 on the key set.

When the protective film 120 is, for example, dirty or damaged, and the user wants to remove the protective film 120, since the movable case 111b is detachably configured on the fixed case 111a, the user can remove the movable case 111b (as shown in FIG. 2B), to take out the protective film 120 for cleaning or replacement.

In this embodiment, the material of the protective film 120 is, for example, a transparent elastic material. The elastic material is stretchable and convenient for the user to arrange the protective film 120 on the key set to be protected, and the transparent material allows the user to The characters and symbols on the keys 113 of the key group can be easily identified, so as to facilitate input and manipulation.

In this embodiment, the first engaging portion 122a of the fixing portion 122 is, for example, a notch, and the second engaging portion 111b2 of the movable shell 111b is, for example, a protruding post. The notch can, for example, be configured to surround the covering portion 121 and be a continuous notch. The configuration and shape of the convex post match the configuration and shape of the notch. When the protective film 120 is to be fixed on the keyboard set, the protrusion (the second engaging portion 111b2 ) is inserted into the notch (the first engaging portion 122a ). In this way, the protective film 120 can be firmly arranged on the key set to provide protection, waterproof and dustproof functions.

Although the first clamping portion 122a is described here as an example of a continuous notch surrounding the covering portion 121, however, those of ordinary skill in the art should understand that the first clamping portion 122a may also include multiple The notches communicate with each other, and the arrangement and shape of the second engaging portion 111b2 of the protrusion match the arrangement and shape of the notch, so as to firmly arrange the protective film 120 on the key set. Alternatively, in an embodiment, the first locking portion can be a protrusion, and the second locking portion can be a notch.

In the protective film described in the above embodiments of the present invention and the keyboard body and portable electronic device using the protective film, the covering part covers the key, and the first clamping part of the fixed part and the second clamping part of the movable shell The joints are engaged with each other. In this way, the protective film can be firmly fixed, and effectively prevent dust and moisture from entering the keyboard body, thereby reducing the probability of damage to the keyboard body.

Certainly, the present invention also can have other multiple embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding Changes and deformations should belong to the scope of protection of the appended claims of the present invention.
