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 FIG. 1 and FIG. 2, according to one embodiment, a mounting device for disk drive includes a mounting bracket 10 and a drive bracket 20. The mounting bracket 10 is secured to the drive bracket 20, and the drive bracket 20 is secured to a chassis 30.
Referring to FIG. 3 and FIG. 4, the drive bracket 20 includes a bottom plate 21, a first side plate 22, and a second side plate 23 that is opposite to the first side plate 22. The first and second side plates 22 are located on the bottom plate 21. A first flange 27 extends from a top edge of the first side plate 22, and a second flange 28 extends from a top edge of the second side plate 23. In an embodiment, the first and second side plates 22, 23 are substantially perpendicular to the bottom plate 21, and the first and second flanges 27, 28 are substantially perpendicular to the first and second side plates 22, 23. A receiving space 29 is defined by the bottom plate 21, the first side plate 22, the second side plate 23, the first flange 27, and the second flange 28. A maintaining plate 25 is secured to the first side plate 22 and the second side plate 23, to divide the receiving space 29 into a top portion and a bottom portion. In an embodiment, the maintaining plate 25 is substantially parallel to the bottom plate 21. A first slot 225 is defined in the first side plate 22, and a second slot 235 is defined in the second side plate 23. A connecting portion 231 is connected to the top edge and the bottom edge of the second slot 235. Two protrusions 233 are located on the outer surface of the connecting portion 231 on the second side plate 23. A resilient piece 239 is located on the connecting portion 231 and extends along the second slot 235. The resilient piece 239 includes a pressing portion 2391 and a latching portion 2393. The pressing portion 2391 is located in an end of the slot 235, the latching portion 2393 is engaged with the two protrusions 233. Referring to FIG. 2, a positioning member 80 is secured to a side of the first side plate 22. The positioning member 80 includes two latches 81. The two latches 81 are elastically deformable.
Referring to from FIG. 5 to FIG. 7, the mounting bracket 10 includes a bottom wall 11 and two opposite sidewalls 13, located on the bottom wall 11. In an embodiment, the bottom wall 11 is substantially perpendicular to the two sidewalls 13. Four limiting pieces 113 are located on the bottom wall 11. Each limiting piece 113 defines a mounting hole 1131. The four limiting pieces are substantially parallel to the bottom wall 11. Each sidewall 13 defines two positioning holes 131. Two first locking members 71 and two second locking members 72 are secured in the positioning holes 131. In one embodiment, the two first locking members 71 and the two second locking members 72 may be screws.
A first disk drive 50 is secured to the top portion of the receiving space 29. In one embodiment, the first disk drive 50 may be a 3.5 inch hard disk drive.
A second disk drive 60 includes two side boards 61. Each side board 61 defines two locking holes 611. In one embodiment, the second disk drive 60 may be a 2.5 inch hard disk drive.
In assembly of the second disk drive 60, the second disk drive 60 is located among the bottom wall 11 and the four limiting pieces 113. Each side board 61 abuts two of the four limiting pieces 113. The locking holes 611 are correspondingly aligned with the mounting holes 1131. The second disk drive 60 is secured among the four limiting pieces 113 by a plurality of locking members, such as screws, engaged in the locking holes 611 and the mounting holes 1131.
In assembly of the mounting bracket 10, the two sidewalls 13 correspondingly abut the inner surfaces of first side plate 22 and second side plate 23. The two first locking members 71 are located in the first slot 225 and the second slot 235 and extend out of the first side plate 22 and second side plate 23. The mounting bracket 10 is guided into the receiving space 29 along the first slot 225 and the second slot 235. The latch 81 is elastically deformed by one of the two first locking members 71. The two second locking members 72 are located in the first slot 225 and the second slot 235, and extend out of the first side plate 22 and second side plate 23. Until the two first locking members 71 are blocked by an end of the first slot 225 and the second slot 235, the latch 81 is elastically deformed by one of the two second locking members 72. The resilient piece 239 is elastically deformed by one of the two first locking members 71. One of the two second locking members 72 is engaged in the receiving hole of the positioning member 80. The latch 81 rebounds to prevent the mounting bracket 10 from sliding out of the drive bracket 20. The resilient piece 239 rebounds to bias the mounting bracket 10 towards the first side plate 22, for securing the mounting bracket 10 between the first side plate 22 and the second side plate 23.
In disassembly of the mounting bracket 10, the latch 81 is rotated, and one of the two second locking members 72 disengages from the receiving hole of the positioning member 80. The mounting bracket 10 slides out of the drive bracket 20 along the first slot 225 and the second slot 235.
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 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.
