## Title
Electronic device enclosure

## Abstract

An electronic device enclosure includes a chassis and a cover. The chassis includes a fixing post and defines a receiving space configured to receive a storage device. The cover defines a latching hole. The fixing post is engaged in the latching hole to engage the cover with the chassis and cover the receiving space when no storage device is in the receiving space.

## Background
BACKGROUND
1. Technical Field
The present disclosure relates to electronic device enclosures, more particularly to an electronic device enclosure with a cover.
2. Description of Related Art
A server system may include a plurality of data storage devices. The storage devices are installed together on a chassis. Any voids created by the removal or absence of one or more of the storage devices can adversely effect heat dissipation of the server system.
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.
FIG. 1 illustrates an electronic device enclosure in accordance with an embodiment. The electronic device enclosure includes a chassis 10 and a plurality of covers 50. In one embodiment, the electronic device is a server system.
The chassis 10 includes a bottom plate 11 and two side plates 13. The two side plates 13 extend from opposite sides of the bottom plate 11. The two side plates 13 are substantially parallel to each other and perpendicular to the bottom plate 11. Two dividing plates 15 are extend from the bottom plate 11 to provide receiving areas for data storage devices. The two dividing plates 15 are in a same plane. The plane is substantially parallel to the two side plates 13 and perpendicular to the bottom plate 11. The two dividing plates 15, each of the side plates 13, and the bottom plate 11 cooperatively define a receiving space 113. The receiving space 113 can receive a storage device 20. The storage device 20 may be a hard disk drive, compact disk read-only memory (CD-ROM) drive, digital video disc (DVD) drive, floppy disk drive, for example. Two fixing posts 131 protrude from each of the two side plates 13 and each of the two dividing plates 15 corresponding to the receiving space 113.
Referring to FIG. 2, each of the plurality of covers 50 includes a top wall 51, two sidewalls 53, a front wall 55, and a back wall. The top wall 51 defines an opening 511. Users can conveniently lift up each of the covers 50 via the opening 511. The two sidewalls 53 extend upwards from opposite edges of the top wall 51. The two sidewalls 53 are substantially parallel to each other and perpendicular to the top wall 51. The front wall 55 and the back wall extend upwards from other opposite edges of the top wall 51. Each of the two sidewalls 53 defines two cutouts 531. Two clipping arms 533 are formed on each of the two cutouts 531 and cooperatively define a latching hole 535 corresponding to each of the two fixing posts 131. In one embodiment, the two clipping arms 533 substantially form a U-shape. The latching hole 535 includes a wide portion 5353 and a narrow portion 5351 communicating with the wide portion 5353. A width of the wide portion 5353 is greater than a width of the narrow portion 5351.
When none of the storage device 20 is received in the receiving space 113, one of the covers 50 is put in the empty receiving space 113. This is done by aligning the latching holes 535 with the corresponding fixing posts 131 and pushing down on each of the covers 50 to deform the two clipping arms 533 until the fixing posts 131 extend through the wide portions 5353 to be engaged into the narrow portions 5351. After the fixing posts 131 are engaged, the clipping arms 533 rebound to clip the fixing posts 131. Each of the covers 50 is thereby secured to the chassis 10.
To install the storage device 20 in the receiving space 113 of the chassis 10, an acting force is applied to each of the covers 50 to move each of the covers 50 away from the bottom plate 11 causing the fixing posts 131 to be removed from the narrow portions 5351 to the wide portions 5353. Each of the covers 50 is thereby detached from the chassis 10.
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.
