BACKGROUND
1. Field of the Invention
The present invention relates to fixing apparatuses, and particularly to a fixing apparatus for hard disk drives (HDDs).
2. Description of Related Art
The conventional approach now being adopted to mount an HDD in a computer chassis generally involves placing the HDD in a holding area of a drive bracket; screwing a plurality of screws through side walls of the drive bracket into two sides of the HDD to fasten the HDD on the drive bracket; and mounting the HDD and the bracket in a computer chassis or a mobile HDD rack. For proper balanced installation of the HDD, multiple screws should be fastened at the same time, making installation and removal of the HDD tedious.
What is desired, therefore, is a fixing apparatus which allows convenient installation and removal of an HDD.

DETAILED DESCRIPTION OF THE EMBODIMENT
Referring to FIG. 1, a fixing apparatus in accordance with an embodiment of the present invention is for fixing a hard disk drive (HDD) 100 and includes a first bracket 20, a second bracket 30, a bezel assembly 40, and two shafts 62, 64.
The HDD 100 includes a pair of holes 120 defined in each of two opposite sidewalls thereof.
Referring also to FIG. 2, the first bracket 20 is generally L-shaped and includes a side plate 22, and a transverse member 24 perpendicular to the side plate 22. The transverse member 24 includes a pivoting hole 25 defined in an end portion near the side plate 22, and a pair of parallel spaced resilient tabs 262 extending from a distal free end thereof. Each of the resilient tabs 262 includes a through hole 264 defined therein. The side plate 22 includes a plurality of mounting holes 23 defined therein to retain a plurality of fixing members 50 therein. Each of the mounting holes 23 includes a rectangular recess 232, a cylindrical hole 234, and a pair of slots 236 extending oppositely from and in communication with the cylindrical hole 234 and opposite to each other.
The second bracket 30 is also generally L-shaped and includes a side plate 32, and a transverse member 34 perpendicular to the side plate 32. The transverse member 34 includes a pair of spaced horizontal plates 342. The horizontal plates 342 include a pair of posts 344 extending toward each other from inside surfaces thereof at end portions near the side plate 32 respectively, and a pair of pivoting holes 346 defined in free end portions thereof respectively. Each post 344 includes a sloping distal end. A pivoting portion 35 extends slantingly from the free end portions of the horizontal plates 342. A pivoting hole 352 is defined in the pivoting portion 35. An extension portion 36 extends forward from an end portion of the side plate 32 near the transverse member 34. A wedged block (not shown) extends outward from an outside surface of the extension portion 36. The side plate 32 includes a plurality of mounting holes 322 defined therein to retain a plurality of fixing members 50 therein. Each of the mounting holes 322 has a similar configuration as the mounting hole 23 of the first bracket 20.
The bezel assembly 40 includes a bezel 42, and a handle 44 pivotably engaging with the bezel 42. The handle 44 includes a pair of vertically aligned pivoting holes 442 respectively defined in an upper portion and a lower portion thereof. The bezel 42 includes a receiving space defined therein. A locking hole 422 is defined in an outside wall of the bezel 42 beside the receiving space to engage with the wedged block of the extension portion 36 of the second bracket 30.
Each of the fixing members 50 includes a cap 54, and a pin 52 with one end embedded in the cap 54. The pin 52 is made of metal. The cap 54 is made of shock absorbing material, such as rubber. Each cap 54 includes a rectangular portion 542, a cylindrical portion 544 perpendicularly extending from the rectangular portion 542, and a pair of wedged protrusions 546 extending oppositely from a circumferential wall of the cylindrical portion 544.
The fixing members 50 are attached to the side plate 22 of the first bracket 20, with the rectangular portions 542 of the caps 54 engaging in the rectangular recesses 232 of the side plate 22, the cylindrical portions 544 of the caps 54 engaging in the cylindrical holes 234 of the side plate 22, and the wedged protrusions 546 engaging in the slots 236 of the side plate 22. The fixing members 50 are also attached to the side plate 32 of the second bracket 30 in a same way as to the first bracket 20.
Referring also to FIGS. 3 and 4, in assembly, the first bracket 20 is pivotably attached to the second bracket 30, with the transverse member 24 of the first bracket 20 sandwiched between the horizontal plates 342 of the second bracket 30. The shaft 62 extends through the pivoting holes 346 of the second bracket 30 and the pivoting holes 25 of the first bracket 20. The posts 344 of the second bracket 30 releasably engage in the through holes 264 of the resilient tabs 262 of the first bracket 20. The bezel assembly 40 is pivotably attached to the second bracket 30. The pivoting portion 35 of the second bracket 30 is sandwiched between the upper portion and the lower portion of the handle 44 of the bezel assembly 40. The shaft 64 extends through the through pivoting holes 442 of the handle 44 of the bezel assembly 40 and the pivoting holes 352 of the pivoting portion 35 of the second bracket 30. The extension portion 36 of the side plate 32 of the second bracket 30 extends into the receiving space of the bezel 42 of the bezel assembly 40, with the wedged block engaging in the locking hole 422.
Referring also to FIG. 4, in use, the resilient tabs 262 of the first bracket 20 are squeezed toward each other to release the post 344 of the second bracket 30 from the through holes 264 of the resilient tabs 262. The first bracket 20 is pivoted about the shaft 62 so that the transverse member 24 of the first bracket 20 is moved away from the transverse member 34 of the second bracket 30 and the side plate 22 of the first bracket 20 is moved away from the side plate 34 of the second bracket 30 to allow the HDD 100 to be placed between the first bracket 20 and the second bracket 30. The pins 52 of the fixing members 50 of the second bracket 30 extend into the holes 120 of one sidewall of the HDD 10. Then, the first bracket 20 is pivoted to the HDD 100 so that the pins 52 of the first bracket 20 extend into the holes 120 of the other sidewall of the HDD 100. Thus, the HDD 100 is secured.
To release the HDD 100, the resilient tabs 262 of the first bracket 20 are squeezed each other toward to release the post 344 of the second bracket 30 from the through holes 264 of the resilient tabs 262. The first bracket 20 is pivoted about the shaft 62 away from the second bracket 30. The HDD 100 can then be easily removed.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without deplateing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments.
