BACKGROUND
1. Technical Field
The present disclosure relates to computer enclosures, more particularly to a computer enclosure with a light guide module.
2. Description of Related Art
Computer enclosures usually include a front panel, a switch button attached to the front panel, and a light emitting diode (LED) attached to the front panel. The switch button includes a transparent portion. The LED is located behind the transparent portion. After the switch button is pressed to power on the computer, the LED is powered on and emits light via the transparent portion of the switch button to indicate that the computer is powered on. However, light emitted from the LED can just emit from the switch button. The indicating effect is not very obvious.
Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to FIGS. 1 and 2, an embodiment of a computer enclosure includes a front panel 10, a light guide module 20, a pressable member 30, a switch module 40, and a transparent member 50. The front panel 10 includes a front plate 12 and a top flange 14 connected to the front plate 12. A mounting hole 121 is defined in the front plate 12. An elongate holding slot 141 is defined in the top flange 14. The pressable member 30 includes a pressing portion 32 and an L-shaped resilient arm 34 connected to the pressing portion 32. The transparent member 50 includes an L-shaped main portion 52 and a transparent post 54 protruding from the main portion 52.
Referring to FIG. 3, the light guide module 20 includes a main shell 22, a first transparent board 24, and a second transparent board 26. The main shell 22 includes a base plate 221 and a pair of side plates 223 connected to opposite sides of the base plate 221. The main shell 22 has a closed end and an open end opposite to the closed end. A light guide slot 225 is formed between the side plates 223. An L-shaped gap 227 is defined in each of the side plates 223 at the open end. The first transparent board 24 is configured to cover an upper opening of the light guide slot 225. The second transparent board 26 includes a main plate 261 and a flange 263 extending perpendicularly and downwards from the main plate 261. A shape and size of the main plate 261 is the same as that of the first transparent board 24. In assembly of the light guide module 20, the first transparent board 24 is attached on top edges of the side plates 223 and covers the upper opening of the main shell 22. The main plate 261 abuts the first transparent board 24. The flanges 263 abut vertical edges of the gaps 227.
Referring to FIGS. 4 and 5, the switch module 40 includes a mounting bracket 60, a switch member 70, a first LED 80, and a second LED 90. The mounting bracket 60 includes a first portion 62 configured for mounting the first LED 80 and the second LED 90, and a second portion 64 configured for mounting the switch member 70. The first portion 62 and the second portion 64 are jointed side by side. A height of the first portion 62 is greater than that of the second portion 64. A first mounting slot 621 is defined in the first portion 62 for accommodating the first LED 80. An arc-shaped holding piece 623 protrudes from an edge of the first mounting slot 621 towards a rear side of the first portion 62. A first hook piece 625 protrudes from the rear side and is located adjacent to the first mounting slot 621. The mounting bracket 60 further includes a first support piece 627 and a second support piece 629 protruding from a front side of the mounting bracket 60 (See FIG. 5). A wedge-shaped protrusion 6271 is formed on a distal end of the first support piece 627. A second mounting slot 641 is defined in the second portion 64. A second hook piece 643 extends from the second portion 64 towards the front side. The switch member 70 includes a main body 72 and a switch button 74 attached to the main body 72.
Referring to FIGS. 6 and 7, in assembly of the switch module 40, the main body 72 is mounted in the second mounting slot 641. The second hook piece 643 clasps the main body 72 to secure the switch member 70 in the second mounting slot 641. The switch button 74 extends through a top gap of the second portion 64. The first LED 80 is mounted in the first mounting slot 621 and supported by the holding piece 623. The first hook piece 625 clasps a rear side of the first LED 80 to secure the first LED 80 in the first mounting slot 621. The second LED 90 is held by the first support piece 627 and the second support piece 629. The wedge-shaped protrusion 6271 abuts the second LED 90 and prevents the second LED 90 from sliding off the mounting bracket 60 (see FIG. 7).
Referring to FIG. 8, in assembly of the computer enclosure, the light guide module 20 and the pressable member 30 are mounted in the holding slot 141. The pressing portion 32 is received in the gap 227 and is movable along a vertical direction in the gap 227. A free end of the resilient arm 34 is secured to the front panel 10. The transparent post 54 is mounted in the mounting hole 121. The main portion 52 is secured to an inner side of the front panel 10. The switch module 40 is secured to the inner side of the front panel 10 at a position where the first LED 80 faces the transparent post 54 and the second LED 90 faces the open end of the light guide module 20. The switch button 74 abuts a lower side of a corner of the resilient arm 34. After the pressing portion 32 is pressed, the resilient arm 34 is deformed and urges the switch button 74 to power on the computer. The first LED 80 is lit and generates light that enters the light guide slot 225 and comes through the first transparent board 24 and the second transparent board 26. The second LED 90 is also lit and generates light that emits from the transparent post 54 along the horizontal direction.
