The protective cover includes a base, a first member and a second member. The base includes a sliding portion in an axis direction of the base. The first member includes a first sliding slot and a first fixing portion. The first fixing portion is fixed on the casing. The first sliding slot cooperates with the sliding portion to make the first member slide on the base in the axis direction between a position the first member overlapping the base and a position the first member being stretched out from the base, so as to adjust a length of the protective cover. The second member is disposed on the base, and the second member includes a second fixing portion for being fixed on the casing.
According to another embodiment of the present invention, an electronic device includes a casing, an electronic component and a protective cover. A containing slot is formed on the casing, and the electronic component is disposed inside the containing slot. The protective cover is disposed on the casing for covering the containing slot, and the protective cover includes a base, a first member and a second member. The base includes a sliding portion in an axis direction of the base. The first member includes a first sliding slot and a first fixing portion. The first fixing portion is fixed on the casing.

As shown in FIG. 1 and FIG. 2, the electronic device 30 includes a casing 32, an electronic component 34a, 34b and at least one protective cover 36. In this embodiment, a length of the electronic component 34a is different from a length of the electronic component 34b. Furthermore, a length of the protective cover 36 is adjustable for being adapted to the electronic components 34a, 34b. An amount of the electronic components 34a, 34b and the protective cover 36 of the electronic device 30 is not limited to those mentioned in this embodiment, and it depends on practical demands. In this embodiment, the electronic device 30 is preferably a military or an industrial notebook computer, and the electronic component 34a, 34b is preferably a military or an industrial antenna, such as a Wireless Local Area Network, WLAN, antenna, a Bluetooth antenna and so on.
Furthermore, a first containing slot 321 and a second containing slot 323 are formed on the casing 32. In this embodiment, a length of the first containing slot 321 is different from a length of the second containing slot 323, and the first containing slot 321 and the second containing slot 323 are respectively used for containing the electronic components 34a, 34b. In practical application, the first containing slot 321 and the second containing slot 323 on the casing 32 can be respectively covered by the protective cover 36 for protecting the aforesaid electronic components 34a, 34b. In such a manner, the protective cover 36 of the present invention can cover the first containing slot 321 and the second containing slot 323 when the electronic components 34a, 34b are disposed inside the first containing slot 321 and the second containing slot 323 on the casing 32, so as to protect the electronic components 34a, 34b from collision. On the other hand, since the protective cover 36 is made of plastic materials, it allows electromagnetic waves generated by the electronic components 34a, 34b to pass, resulting in that communication between the electronic components 34a, 34b and an external electronic component is not shielded by the protective cover 36. In summary, the protective cover 36 of the present invention not only protects the electronic components 34a, 34b from collision, but also allows the electronic components 34a, 34b covered by the protective cover 36 to communicate with the external electronic component.
Please refer to FIG. 3 to FIG. 5. FIG. 3 is a diagram of the protective cover 36 according to the first embodiment of the present invention.

Additionally, the first member 40 includes a first sliding slot 401, and the second member 42 includes a second sliding slot 421. The first sliding slot 401 of the first member 40 cooperates with the sliding portion 381a on the base 38, such that the first member 40 can slide in the axis direction X by the sliding portion 381a on the base 38. Similarly, the second sliding slot 421 of the second member 42 cooperates with the sliding portion 381b on the base 38, such that the second member 42 can slide in the axis direction X by the sliding portion 381a on the base 38. In such a manner, the first member 40 can slide on the base 38 relative to the second member 42 between a position the first member 40 overlapping the base 38 and a position the first member 40 being stretched out from the base 38, so as to adjust the length of the protective cover 36.
In this embodiment, a shape of the first member 40 is substantially identical to a shape of the second member 42. When the first member 40 and the second member 42 are installed, the sliding portion 381a on the base 38 is disposed inside the first sliding slot 401 of the first member 40 first, and then the sliding portion 381b on the base 38 is disposed inside the second sliding slot 421 of the second member 42. In such a manner, since the sliding portions 381a, 381b are respectively located on the two opposite end portions P1, P2 of the base 38, the first member 40 and the second member 42 can be installed on two opposite sides of the base 38. In other words, the first member 40 and the second member 42 are symmetrically disposed on the base 38, and the first member 40 is capable of sliding on the base 38 relative to the second member 42. In this embodiment, the sliding portions 381a, 381b can be, but not limited to, respectively a sliding track. For example, the sliding portions 381a, 381b can be respectively a protruding structure as well. In other words, structures allowing the sliding portions 381a, 381b to be respectively slidably disposed inside the first sliding slot 401 of the first member 40 and the second sliding slot 421 of the second member 42 are within the scope of the present invention.
