FIG. 2 is a partial top plan view of a keyboard according to an embodiment of the present invention. FIG. 3 is a schematic partial cross-sectional view of the keyboard of FIG. 2 along section line I-I. Please refer to Figure 1 to Figure 3, in this real In the embodiment, the keyboard 10 includes a casing 11 , a plurality of keycaps 12 and a keyboard protective film 100 , wherein the casing 11 includes a plurality of partitions 11 a , and the plurality of partitions 11 a define a plurality of openings 13 . The plurality of keycaps 12 are respectively disposed above the housing 11 corresponding to the plurality of openings 13 , and any two adjacent keycaps 12 are separated by a partition 11a. When either keycap 12 is depressed, at least a portion of the keycap 12 moves into the corresponding opening 13 . Correspondingly, when any one of the key caps 12 is lifted and reset, the key cap 12 is moved out of the corresponding opening 13 .

The keyboard protection film 100 is detachably disposed on the casing 11 and the plurality of keycaps 12 to cover the casing 11 and the plurality of keycaps 12 . Protected by the keyboard protective film 100, the external force cannot directly act on the casing 11 and the plurality of keycaps 12, and foreign objects cannot directly contact the casing 11 and the plurality of keycaps 12, so the casing 11 and the plurality of keycaps 12 can be prevented from being directly contacted. The plurality of keycaps 12 are subject to wear or contamination. In addition, the keyboard protective film 100 can also block the way of external dust or moisture entering the interior of the keyboard 10 , thereby helping to reduce the probability of failure or damage of the keyboard 10 .

Please refer to FIG. 2 and FIG. 3 , the keyboard protection film 100 includes a base 110 for covering the casing 11 and a plurality of key cap protection parts 120 protruding from the base 110 , and the key cap protection parts 120 are used to cover the plurality of keycaps 12 . Further, the base portion 110 has a bottom surface 111 facing the plurality of partition portions 11a, and the bottom surface 111 is separated from or suspended from the plurality of partition portions 11a. Furthermore, each partition 11a has a partition top surface 11b, and the bottom surface 111 of the base 110 faces the partition top surfaces 11b of the partition parts 11a, and the bottom surface 111 is separated from or suspended from the partition parts 11a. A plurality of partition top surfaces 11b. That is, the bottom surface 111 of the base 110 does not contact the The plurality of partition top surfaces 11b of each partition portion 11a.

On the other hand, each keycap protection portion 120 has a first positioning surface 121 and a second positioning surface 122 connected to the first positioning surface 121 , and the first positioning surface 121 and the second positioning surface 122 form a keycap receiving groove 123 . The first positioning surface 121 and the second positioning surface 122 of each keycap protection portion 120 face the corresponding keycap 12 , wherein the second positioning surface 122 is connected to the bottom surface 111 of the base portion 110 , and the second positioning surface 122 is located on the first positioning surface 121 and the bottom surface 111.

Please refer to FIG. 3 , the keycaps 12 are respectively disposed in the keycap accommodating grooves 123 , and each keycap 12 has a pressing surface 12a and a side wall surface 12b connected to the pressing surface 12a. The first positioning surface 121 of each keycap protection portion 120 contacts the pressing surface 12a of the corresponding keycap 12 , and the second positioning surface 122 faces the sidewall surface 12b of the corresponding keycap 12 . Because each first positioning surface 121 in contact with the corresponding pressing surface 12a is the cooperation of two smooth surfaces, the van der Waals force generated between each first positioning surface 121 in contact and the corresponding pressing surface 12a (van der Waals' Forces) enhancement, so that each keycap protection part 120 can be closely attached and fixed to the corresponding keycap 12 through Van der Waals force, preventing the keyboard protection film 100 from being on the plurality of keycaps 12 Offset or easily detached from the plurality of keycaps 12 .

On the other hand, because each first positioning surface 121 in contact with the corresponding pressing surface 12a is the cooperation of two smooth surfaces, under the action of the external atmospheric pressure, each keycap protection portion 120 can be closely attached to the corresponding pressing surface 12a. On the keycaps 12 , the keyboard protection film 100 is prevented from being displaced on the keycaps 12 or easily detached from the keycaps 12 .

The second positioning surface 122 of each keycap protection portion 120 contacts the sidewall surface 12b of the corresponding keycap 12, because each second positioning surface 122 in contact with the corresponding sidewall surface 12b is the cooperation of two non-smooth surfaces, The van der Waals' Forces generated between each second positioning surface 122 in contact with the corresponding side wall surface 12b are weakened, so that each second positioning surface 122 can still be relative to the corresponding side wall surface 12b is slid and fixed on the corresponding side wall surface 12b instead of sticking.

In this embodiment, the surface roughness of the second positioning surface 122 of each keycap protection portion 120 is greater than the surface roughness of the first positioning surface 121. In another embodiment, the surface roughness of the sidewall surface 12b of each keycap 12 is The surface roughness is larger than the surface roughness of the pressing surface 12a. For example, the surface roughness of the first positioning surface 121 of each keycap protection part 120 may be equal to the surface roughness of the pressing surface 12a of each keycap 12 , and the second positioning surface of each keycap protection part 120 The surface roughness of 122 may be equal to the surface roughness of the side wall surface 12b of each keycap 12 .

Please refer to FIG. 2 and FIG. 3 , the keyboard protective film 100 further includes a positioning portion 130 connected to the edge of the base portion 110 , and the housing 11 has a positioning groove 14 corresponding to the positioning portion 130 . The positioning portion 130 is inserted into the positioning groove 14 to improve the bonding strength between the keyboard protection film 100 and the casing 11 . Further, the positioning groove 14 has a positioning concave surface 14a, and the positioning portion 130 has a positioning convex surface 131 contacting the positioning concave surface 14a. Because the contacting positioning convex surface 131 and the positioning concave surface 14a are two smooth surfaces, the van der Waals force generated between the contacting positioning convex surface 131 and the positioning concave surface 14a is enhanced, so that the positioning portion 130 can pass through the van der Waals force. It is tightly attached and fixed in the positioning groove 14 of the casing 11 to prevent the keyboard protective film 100 from being displaced on the casing 11 or easily detached from the casing body 11.

For example, the surface roughness of the first positioning surface 121 of each keycap protection portion 120 , the pressing surface 12a of each keycap 12 , the positioning convex surface 131 of the positioning portion 130 and the positioning concave surface 14a of the positioning groove 14 may be equal. of. On the other hand, the keyboard protection film 100 can be made of silicone, so it can be bent or deformed elastically. That is, the base portion 110 , the plurality of keycap protection portions 120 and the positioning portion 130 may be formed of a homogeneous material.

Based on the design of the surface roughness of the contact surface between the keyboard protection film 100 and the casing 11 and the design of the surface roughness of the contact surface between the keyboard protection film 100 and the keycap 12 , the keyboard protection film 100 can be attached and fixed The housing 11 and the keycap 12 are not offset or easily separated from the housing 11 and the keycap 12 , so they have excellent reliability. In the process of disassembling and assembling the keyboard protective film 100 by the user, since there is no need for dispensing or removing glue, it not only helps to improve the convenience of disassembly and assembly, but also does not cause the problem of colloid residue.
