## Background
BACKGROUND
1. Technical Field
The present disclosure relates to computer enclosures, and particularly to a computer enclosure with a cover.
2. Description of Related Art
In a computer enclosure or a sever enclosure, the front panel of the enclosure defines an opening for receiving expansion ports, such as a USB port. The expansion ports are uncovered, so the expansion ports may encounter environmental hazards such as dust and moisture, thus reducing the lifespan of the expansion ports.
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 FIG. 1, an enclosure includes a chassis 10, a front panel 20, and a cover 30.
Referring to FIG. 2, the front panel 20 defines an opening 21. Two mounting boards 23 are located on an inner side of the front panel 20 and arranged at two opposite sides of the opening 21. In one embodiment, the two mounting boards 23 are substantially parallel to each other. Each of the two mounting boards 23 defines a first slot 231 and a second slot 233 below the first slot 231. The first slot 231 includes a first short portion 2311, a first long portion 2313 communicating with the first short portion 2311, and a stopping portion 2315 communicating with the first long portion 2313. In one embodiment, an extension direction of the first long portion 2313 is substantially parallel to each of the two mounting boards 23, and an obtuse angle is defined between the first short portion 2311 and the first long portion 2313. The second slot 233 includes a second short portion 2331 and a second long portion 2333 communicating with the second short portion 2331. In one embodiment, an obtuse angle is defined between the second short portion 2331 and the second long portion 2333. Each of the two mounting boards 23 defines a recess 235 placed in the back of the second slot 233. A receiving space 237 is defined between the two mounting boards 23 and is placed on the top of the opening 21, for receiving the cover 30.
Referring to FIG. 3, the cover 30 includes a base wall 31 and two sidewalls 33 located on two opposite sides of the base wall 31. In one embodiment, each of the two sidewalls 33 is substantially perpendicular to the base wall 31, and the base wall 31 is substantially rectangular. The base wall 31 and the two sidewalls 33 cooperatively define an installation space 35 for receiving an expansion device 5 (shown in FIG. 5). A covering portion 311 is located in the front of the base wall 31. The covering portion 311 includes four connecting portions 3111 and a covering board 3113 connected to the four connecting portions 3111. In one embodiment, each of the four connecting portions 3111 is substantially perpendicular to the base wall 31, and the covering board 3113 is substantially parallel to the base wall 31. An operating portion 313 extends from the covering board 3113. In one embodiment, the operating portion 313 is substantially arc-shaped.
A resilient piece 331 extends from each of the two sidewalls 33. A first latching portion 3311 is located on the distal end of the resilient piece 331. In one embodiment, the resilient piece 331 and the sidewall 33 are in the same plane. The sidewall 33 defines a groove 3313 around the resilient piece 331. The resilient piece 331 is elastically deformable in the groove 3313. An extension piece 333 extends from the distal end of each of the two sidewalls 33. A second latching portion 3331 is located on distal end of the extension piece 333. A protrusion 335 is located on the sidewall 33 above the second latching portion 333, and the protrusion 335 is located on a right edge of each sidewall 33. In one embodiment, a line connecting the first latching portion 3311 and the second latching portion 3331 is substantially parallel to the base wall 31.
Referring to FIGS. 1 and 4, in assembly, the cover 30 is located at an inner side of the front panel 20. The resilient piece 331 and the extension piece 333 are squeezed by the corresponding sidewall 30 to be elastically deformed, until the first latching portion 3311 is aligned with the short portion 2311 of the first slot 231, and the second latching portion 3331 is aligned with the short portion 2311 of the second slot 233. The resilient piece 331 and the extension piece 333 elastically return. The first latching portion 3311 is engaged in the short portion 2311 of the first slot 231, and the second latching portion 3331 is engaged in the short portion 2311 of the second slot 233. The protrusion 335 is engaged in the recess 235. The cover 30 is in a first position, where the covering portion 311 is received in the opening 21, the covering board 3113 is covering the opening 21, and the operating portion 313 is exposed on an outer side of the panel 20.
Referring to FIG. 5, the operating portion 313 is biased to slide the cover 30. The first latching portion 3311 and the second latching portion 3331 are slid along the long portion 2313, until the first latching portion 3311 is engaged in the stopping portion 2315. The cover 30 is in a second position, where the covering portion 311 is received in the receiving space 237 to uncover the opening 21.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
