## Background
BACKGROUND
1. Technical Field
The present invention relates to computer enclosures, and more particularly to a computer enclosure with a bracket for receiving disk drives.
2. General Background
In a computer or a sever, a disk drive is needed. A bracket is usually provided to secure the disk drive therein. However, the kind of bracket is only used to secure the disk drive, but cannot be used to secure other electronic devices, such as PCI (Peripheral Component Interconnection) cards.
What is needed, therefore, is a computer enclosure having a bracket for securing at least one disk drive therein and allowing a PCI card securing thereon.
SUMMARY
A computer enclosure includes a chassis, and a bracket secured in the chassis. The bracket includes a holding portion configured for receiving at least one disk drive therein and an expansion portion configured for securing a PCI card thereon. The expansion portion is integrally formed on an outside of the holding portion.
Other advantages and novel features will be drawn from the following detailed description of preferred embodiments with attached drawings, in which:

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to FIG. 1, a computer enclosure of a preferred embodiment of the present invention includes a chassis 10, and a bracket 30 detachably attached to the chassis 10.
The chassis 10 includes a bottom plate 12, a side plate 14, and a rear plate 18. The side plate 14 and the rear plate 18 are perpendicularly formed on adjacent edges of the bottom plate 12, and perpendicular to each other. A motherboard 20 is secured on an inner surface of the bottom plate 12. An expansion slot 22 is disposed on the motherboard 20 and extends along a direction perpendicular to the rear plate 18. A convex portion 122 with a mounting hole 124 defined therein is disposed on the inner surface of the bottom plate 12 between the motherboard 20 and the side plate 14. The rear plate 18 defines an opening 182 adjacent the side plate 14 thereof. Three bent flanges 1822, 1824, and 1826 are perpendicularly bent from a bottom and two side edges of the opening 182 respectively. A cutout 1828 is defined in a top portion of the bent flange 1826 along a direction perpendicular to the bottom plate 12.
The bracket 30 includes a holding portion 32 for receiving disk drives therein, and an expansion portion 34 extending from the holding portion 32. The holding portion 32 includes a bottom wall 322, a top wall 324 parallel to the bottom wall 322, and parallel first and second side walls 326, 328 both perpendicular to the bottom wall 322. A rim 3222 is perpendicularly bent down from a rear edge of the bottom wall 322. A bent piece 3282 is perpendicularly formed on a front edge of the second side wall 328 toward the first side wall 326. A hollow restricting portion 3284 is formed on an outer surface of the bent piece 3282. A positioning piece 3286 with a through hole 3288 defined therein is formed on the bent piece 3282 below the restricting portion 3284. The expansion portion 34 includes a first retaining wall 342 bent perpendicularly out from the first side wall 326 of the holding portion 32, and a second retaining wall 344 bent perpendicularly out from the first retaining wall 342. A support flange 3422 is perpendicularly formed on a top edge of the first retaining wall 342. A PCI opening 3424 is defined in the first retaining wall 342 and the support flange 3422. A securing hole 3426 is defined in the support flange 3422. A post 3442 is disposed on the second retaining wall 344, corresponding to the cutout 1828 of the bent flange 1826 of the rear plate 18. A rim 3444 is perpendicularly formed on a rear edge of the second retaining wall 344.
A PCI (peripheral component interconnection) card 40 has an L-shaped mounting piece 42 for securing the PCI card 40 on the expansion portion 344 of the bracket 30 and shielding the PCI opening 3424, and an inserting portion 44 for inserting into the expansion slot 22 of the motherboard 20. The mounting piece 42 defines a locking hole 422 therein, corresponding to the securing hole 3426 of the expansion portion 344 of the bracket 30. Alternatively, other expansion cards can also be used.
See FIG. 2, the bracket 30 is placed into the chassis 10 with the rear end thereof being received into the opening 182 of the rear plate 18. The post 3442 of the bracket 30 is slid into the cutout 1828 of the rear plate 18. The positioning piece 3286 of the second side wall 328 is located above the convex portion 122 of the bottom plate 12, and the through hole 3288 aligns with the mounting hole 124 of the convex portion 122. The bottom wall 322 is supported on the bent flange 1822 of the rear plate 18, and the second side wall 328 abuts on the bent flange 1824, and the end of the rim 3222 abuts on the bent flange 1826. The rims 3222, 3444 are positioned at the exterior of the chassis 10 and abut an outer surface of the rear plate 18. A locking member 50, such as an elongated thumb-screw, is inserted through the restricting portion 3284 and the through hole 3288 of the positioning piece 3286 thereby being locked into the mounting hole 124 of the convex portion 122 of the bottom plate 12. Thus, the bracket 30 is stably secured into the chassis 10.
The inserting portion 44 of the PCI card 40 is inserted into the PCI slot 22 of the motherboard 20. The mounting piece 42 is inserted into the PCI opening 3424 of the first retaining wall 342 of the expansion portion 342 with a top portion thereof abutting on the top portion of the support flange 3422. The locking hole 422 aligns with the securing hole 3426 of the support flange 3422 of the first retaining wall 342. A screw 60 is inserted through the locking hole 422 of the mounting piece 42 of the PCI card 40, and locked into the securing hole 3426 of the first retaining wall 342. Thus, the PCI card 40 is stably secured into the chassis 10 on the expansion portion 34 of the bracket 30.
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.
