Each shaft 80 is made of damping material.
Referring to FIGS. 1-5, in assembly, the latching members 55 are placed to engage with inner surfaces of the side plates 523 of the shell 52. The positioning portion 553 and the operating portion 556 of each latching member 55 are inserted in the positioning hole 5233 and the operation hole 5235 of the corresponding side plate 523, and the installing holes 555 are aligned with the connecting holes 5237 of the side plate 523. A first part of the fastening members 90 extends through the connecting holes 5237 of the side plate 523, to be fastened in the corresponding installing holes 555 of the latching member 55. Thus, the latching members 55 are mounted to the side plates 523. The latching members 65 are placed to engage with inner surfaces of the side plates 623 of the shell 62. The positioning portion 653 and the operating portion 656 of each latching member 65 are inserted in the positioning hole 6233 and the operation hole 6235 of the corresponding side plate 623, and the installing holes 655 are aligned with the connecting holes 6237 of the side plate 623. A second part of the fastening members 90 extends through the connecting holes 6237 of the side plate 623, to be fastened in the corresponding installing hole 655 of the latching member 65. Thus, the latching members 65 are mounted to the side plates 623. The other part of hard disk drives 70 are supported on the bottom plates 521 and 621, and a third part of the fastening members 90 extend through the mounting holes 526 and 626 to be mounted to the hard disk drives 70.
The second bracket 60 installing a part of the hard disk drives 70 is received in the receiving space 26 of the enclosure 20, the second rotating holes 6231 of the second bracket 60 are aligned with the second shaft holes 234 of the enclosure 20, and the bottom plate 621 of the second bracket 60 is supported on the hard disk drives 70 mounted on the bottom wall 21 of the enclosure 20. The positioning portions 653 of the latching members 65 resiliently abut against inner surfaces of the side walls 23, to deform the latching pieces 651 away from the corresponding side walls 23. Two of the shafts 80 extend though the second shaft holes 234, to be inserted into the second rotating holes 6231 of the second bracket 60. Thus, the second bracket 60 can be rotatably connected to the enclosure 20, the latching holes 6238 are aligned with the corresponding through holes 235 of the enclosure 20, and a fourth part of the fastening members 90 extends through the through holes 235 to fasten the corresponding latching hole 6238.
The first bracket 50 installing the other hard disk drives 70 is received in the receiving space 26 of the enclosure 20, the first rotating holes 5231 of the first bracket 50 are aligned with the first shaft holes 232 of the enclosure 20, and the bottom plate 521 of the first bracket 50 is supported on the second bracket 60. The positioning portions 553 of the latching members 55 resiliently abut against inner surfaces of the side walls 23, to deform the latching pieces 551 away from the corresponding side walls 23. Two of the shafts 80 extend though the first shaft holes 232, to be inserted into the first rotating holes 5231 of the first bracket 50. Thus, the first bracket 50 is rotatably connected to the enclosure 20, and the latching holes 5238 are aligned with the corresponding through holes 235 of the enclosure 20, and a fifth part of the fastening members 90 extends through the through holes 235 to fasten the corresponding latching hole 5238.
Referring to FIGS. 6 and 7, if one of the hard disk drives 70 mounted to the bottom wall 21, the second bracket 60, or the first bracket 50 needs to be replaced, the fastening members 90 are detached from the side walls 23, the first bracket 50 is pulled up to rotate about the first shaft holes 232. The positioning portion 553 of each latching member 55 slidably abuts against the inner surface of the corresponding side wall 23, until the positioning portion 553 is exposed out of a top edge of the corresponding side wall 23. The latching pieces 551 are restored to bias the operating portions 556 and the positioning portions 553 to extend through the operation holes 5235 and the positioning holes 5233, and to allow the position surfaces 557 of the positioning portions 553 to latch on the top edges of the side walls 23. Thus, the first bracket 50 is substantially perpendicularly positioned to the enclosure 20 for installing or removing the hard disk drives 70 of the first bracket 50. The second bracket 60 is pulled up to rotate about the second shaft holes 234. The positioning portion 653 of each latching member 65 slidably abuts against the inner surface of the corresponding side wall 23, until the positioning portion 653 is exposed out of the top edge of the corresponding side wall 23. The latching pieces 651 are restored to bias the operating portions 656 and the positioning portions 653 to extend through the operation holes 6235 and the positioning holes 6233, and to allow the position surfaces 657 of the positioning portions 653 to latch on the top edges of the side walls 23. Thus, the second bracket 60 is substantially perpendicularly positioned to the enclosure 20 for installing or removing the hard disk drives 70 of the second bracket 60, and it is convenient to install or remove the hard disk drives 70 supported on the bottom wall 21.
The operating portion 656 of each latching member 65 is pressed to receive in the corresponding operation hole 6235, to deform the corresponding latching piece 651, and the positioning surface 657 is detached from the top edge of the corresponding side wall 23. The second bracket 60 is pushed toward the receiving space 26, the second bracket 60 is rotated about the corresponding shafts 80, until the second bracket 60 is supported on the hard disk drives 70 mounted to the bottom wall 21. The operating portion 556 of each latching member 55 is pressed to receive in the corresponding operation hole 5235, to deform the corresponding latching piece 551, and the positioning surface 557 is detached from the top edge of the corresponding side wall 23. The first bracket 50 is pushed toward the receiving space 26, the first bracket 50 is rotated about the corresponding shafts 80, until the first bracket 50 is supported on the hard disk drives 70 mounted to the second bracket 60. The fastening members 90 extend through the through holes 235 to fasten in the corresponding latching holes 5238 and 6238.
Even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the present disclosure is illustrative only, and changes may be made in detail, including in the matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
