## Background
FIELD OF THE INVENTION
The present invention relates to computer enclosures, and more particularly to a computer enclosure with a disk drive bracket.
GENERAL BACKGROUND
When a conventional computer is assembled, at least a disk drive bracket is mounted in a computer enclosure. Data storage devices such as a hard disk drive, a floppy disk drive, and a compact disk read only memory drive are then attached to the drive bracket.
A disk drive bracket is usually secured to a computer enclosure between one side panel and a front panel of the computer enclosure. U.S. Pat. No. 6,644,762 discloses a computer enclosure including a front panel, a first drive bracket and a second drive bracket. A first opening and a second opening are defined in the front panel, corresponding to the first and second drive brackets. A plurality of clips extends inwardly from the front panel adjacent the first and second openings. A projection is formed on a middle portion of each clip. The first and second drive brackets each comprise a top panel, a bottom panel, and a side panel. An edge portion of each of these panels nearest the front panel is bent vertically to respectively form a plurality of bent panels. Each bent panel defines a pair of slots; except the bent panel of the bottom panel of the first drive bracket, which defines a pair of gateways. A plurality of recessed portions is formed in the panels of the first and second drives brackets, respectively corresponding to the slots of the bent panels. Each recessed portion defines a cutout therein. The clips of the front panel are received in the slots of the first and second drive brackets, and engaged with the corresponding recessed portions of the first and second drive brackets. The first and second drive brackets are thereby securely attached to the front panel.
However, the typical computer enclosure has a complicated structure, furthermore, when a plurality of storage devices is assembled into the drive brackets and vibration occurs, the bottom panels of the drive brackets are prone to be distorted.
What is needed, therefore, is a computer enclosure having a simple structure and a disk drive bracket which is not prone to be distorted.
SUMMARY
A computer enclosure includes a disk drive bracket and a chassis. The disk drive bracket includes a bottom wall and a pair of sidewalls connecting with two opposite sides of the bottom wall, at least a fixing hole is defined in the bottom wall of the disk drive bracket, a plurality of parallel sideways extends upwards from the bottom wall of the disk drive bracket. The chassis includes a bottom panel supporting the bottom wall of the disk drive bracket and a pair of side panels resisting against the sidewalls of the disk drive bracket respectively, at least a standoff engaging into the fixing hole of the disk drive bracket extends upwardly from the bottom panel, a plurality of parallel guideways are formed on the bottom panel of the chassis for engaging with the slideways of the disk drive bracket.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to FIG. 1, a computer enclosure in accordance with a preferred embodiment of the present invention includes a disk drive bracket 10 configured for accommodating a plurality of data storage devices (not shown) therein, a chassis 20 configured for receiving the disk drive bracket 10 and a plurality of other electronic components (not shown) therein, and a pair of screws 30.
Referring to FIG. 1 and FIG. 2, the disk drive bracket 10 includes a bottom wall 12, a pair of sidewalls 14 connecting with two opposite sides of the bottom wall 12 respectively, a plurality of parallel dividing walls 16, and a top wall 18 covered on the sidewalls 14 and the dividing walls 16. The bottom wall 12, the sidewalls 14, and the top wall 18 cooperatively configure a casing space. The dividing walls 16 divide the casing space into four portions for installing a plurality of disk drives. A plurality of generally teardrop shaped fixing holes 121 is defined in the bottom wall 12 of the disk drive bracket 10. Wider portions of the fixing holes 121 are called entrance apertures 1213, and narrow portions of the fixing holes 121 are called fixing apertures 1211. A plurality of long narrow, parallel openings 125 is defined in the bottom wall 12 of the disk drive bracket 10, a generally arc-shaped slideway 123 extends up from a long edge of each opening 125. A flange 141 extends out perpendicularly from each sidewall 14 of the disk drive bracket 10. A securing hole 143 is defined in each of the flange 141.
Referring to FIG. 1, the chassis 20 includes a bottom panel 22 and a pair of opposite side panels 24 connecting with the bottom panel 22. A plurality of standoffs 221 corresponding to the fixing holes 121 respectively, extend up from the bottom panel 22 of the chassis 20. Each of the standoffs 221 includes a neck portion 2211 and a head portion 2213. A plurality of long, narrow parallel guideways 223 corresponding to the slideways 123 of the disk drive bracket 10 are protruded from the bottom panel 22 of the chassis 20. The guideways 223 are generally arc shaped in cross section with a same arc length and curvature as cross sections of the slideways 123 of the disk drive bracket 10. In profile, a height of the guideways 223 is less than that of the standoffs 221. A flange 241 corresponding to the flange 141 of the disk drive bracket 10 extends out perpendicularly from each of the side panels 24 of the chassis 20 respectively. A securing hole 243 is defined in each flange 241, corresponding to the securing holes 143 of the disk drive bracket 10. Wherein a diameter of each of the entrance aperture 1213 of the fixing holes 121 of the disk drive bracket 10 is bigger than that of the heads 2213 in cross section. A diameter of each of the fixing apertures 1211 of the fixing holes 121 of the disk drive bracket 10 is less than that of the heads 2213 in cross section, and is approximately the same as that of the of the necks 2211 in cross section. A length of the bottom wall 12 of the disk drive bracket 10 is equal to the width of the bottom panel 22 of the chassis 20.
Referring to FIGS. 1 to 3, in assembly of the disk drive bracket 10, the standoffs 221 of the chassis 20 are inserted through the entrance apertures 1213 of the fixing hole 121 of the disk drive bracket 10, and the slideways 123 of the disk drive bracket 10 are placed on the guideways 223 of the chassis for facilitating sliding of the disk drive bracket 10 into position. Then the disk drive bracket 10 is pushed rearward along the guideways 223 of the chassis 20 until the necks 2211 of the standoffs 221 engage into the fixing apertures 1211 of the fixing holes 121 of the disk drive bracket 10, and the sidewalls 14 and the flanges 141 of the disk drive bracket 10 resist against the side panel 24 and flanges 241 of the chassis 20 respectively. At this point, the securing holes 143 of the flange 141 of the disk drive bracket 10 are aligned with the securing holes 243 of the flange 241 of the chassis 20, and a pair of screws 30 is inserted though the securing holes 143 and 243, fastening the disk drive bracket 10 into the chassis 20. Thus, the data storage devices can be secured into the chassis via the disk drive bracket 10.
In disassembly of the disk drive bracket 20, the screws 30 are removed from the securing holes 243 and 143, then the disk drive bracket 10 is pulled out along the guideways 223 of the chassis 20 until the necks 2211 of the standoffs 221 slide from the fixing apertures 1211 to the entrance apertures 1213 of the fixing hole 121 of the disk drive bracket 10. Then the disk drive bracket 10 is taken out from the chassis 20 after the standoffs 221 of the chassis 20 are totally disengaged from the fixing holes 121 of the disk drive bracket 10.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of preferred embodiments, together with details of the structures and functions of the preferred embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
