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 FIGS. 1 and 2, one embodiment of a disk drive assembly is shown. The disk drive assembly includes an enclosure 10, a printed circuit board 20, a back board 30, a drive bracket 40, and a plurality of disk drives 50.
The enclosure 10 includes a bottom wall 11, two first side walls 12, and two second side walls 13. The two first side walls 12 are substantially parallel to each other and substantially perpendicular to the bottom wall 11. The two second side walls 13 are substantially parallel to each other and substantially perpendicular to the bottom wall 11. The second side wall 13 is substantially perpendicular to the first side wall 12.
The printed circuit board 20 is mounted on the bottom wall 11 and substantially parallel to the bottom wall 11. The printed circuit board 20 includes a Central processing unit (CPU) (not shown).
The back board 30 is electrically connected to the printed circuit board 20. The back board 30 defines a plurality of inserting slots 31 corresponding to the disk drives 50.
The drive bracket 40 includes five side panels 41, a mounting portion 43, an isolating panel 45. The mounting portion 43 includes a first mounting panel 431, a second mounting panel 432 substantially parallel to the first mounting panel 431, and a connecting panel 433 connected between the first mounting panel 431 and the second mounting panel 432. Each side panel 41 includes a plurality of guiding portions 411. Each guiding portion 411 extends substantially perpendicular to the back board 30.
The structures of the first mounting panel 431 and the second mounting panel 432 are similar to the structure of the side panel 41. The first mounting panel 431 is substantially parallel to the side panel 41. Some of the disk drives 50 are mounted between the first mounting panel 431 and the side panel 41 adjacent to the first mounting panel 431. Some of the disk drives 50 are mounted between the second mounting panel 432 and the side panel 41 adjacent to the second mounting panel 432. Some of the disk drives 50 are mounted between the two adjacent side panels 41. The side panels 41 are substantially perpendicular to the second side wall 13. The length of the side panel 41 is substantially equal to the distance between the two second side wall 13.
Referring to FIGS. 3 and 4, in assembly, the printed circuit board 20 is mounted on the bottom wall 11 of the enclosure 10. The back board 30 is electrically connected to the printed circuit board 20. The back board 30 is substantially parallel to the printed circuit board 20. The drive bracket 40 is mounted in the enclosure 10 to enable one side panel 41 of the drive bracket 40 to contact the first side wall 12. Some of the disk drives 50 are mounted between the second mounting panel 432 and the side panel 41 adjacent to the second mounting panel 432. Some of the disk drives 50 are mounted between the two adjacent side panels 41. The disk drives 50 slide into the drive bracket 40 via the guiding portions 411 substantially perpendicular to the back board 30 and perpendicular to the side panel 41.
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.
