BACKGROUND
1. Technical Field
The present disclosure relates to electronic devices, and more particularly, to an electronic device with a mounting apparatus for mounting a hard disk drive (HDD).
2. Description of Related Art
In computers, a HDD stores information. The HDD is usually mounted in a bracket of the computer. The HDD is directly inserted into the bracket, and a large number of screws extend through sidewalls of the bracket to fix the HDD to the bracket. However, mounting or removing the HDD to or from the bracket requires a tool to fasten or release the screws. Thus, the assembly and disassembly of the HDD are not only time-consuming but also laborious.

Two opposite ends of the sliding plate 62 define receiving slots 64 extending along the lengthwise direction of the sliding plate 62. A resilient tongue 65 extends into each receiving slot 64 from an end wall bounding the receiving slot 64 adjacent to a middle portion of sliding plate 62. A wedge-shaped abutting block 66 extends out from a distal end of each tongue 64. Each abutting block 66 defines a slanting guiding surface 67 opposite to the middle portion of the sliding plate 62.
FIG. 4 shows that the unlocking member 70 made of resilient material, including a substantially rectangular abutting plate 72 and an operation plate 74 slantingly extending out from a front end of the abutting plate 72. A rear end of the abutting plate 72 defines a position hole 75 opposite to the operation plate 74. A junction of the operation plate 74 and the abutting plate 72 defines a rectangular through hole 76. A resilient tongue 77 extends into the through hole 76 from an end wall bounding the through hole 76 adjacent to the operation plate 74. A distal end of the tongue 77 defines a mounting hole 772.
FIGS. 5-6 show that, in assembly, the bracket 40 is supported on the bottom wall 202 of the chassis 200. The through holes 46 of the bracket 40 align with the screw holes 204 of the bottom wall 202. A plurality of screws extends through the through holes 46, to be screwed in the screw holes 204. The bracket 40 and the chassis 200 cooperatively bound an installing space 26. The unlocking member 70 is sandwiched between the supporting plate 512 with the operation hole 517 and the position plate 513, to allow the operation plate 74 of the unlocking member 70 to be received in the operation hole 517. The latching pole 5136 is latched in the mounting hole 772, the unlocking member 70 is thus mounted to the shell 51. The position hole 75 of the unlocking member 70 aligns with the receiving portion 5135 of the installing hole 5132. Front ends of the rails 60 are inserted into the slide slots 515. The sliding plates 62 slidably abut against inner surfaces of the supporting plates 512. The guiding surfaces 67 of the abutting blocks 66 at the front ends of the rails 60 slidably abut against the supporting plate 512, deforming the tongues 65, until the abutting blocks 66 align with the second locating holes 516. The tongues 65 restore to bias the abutting blocks 66 to being latched in the second locating holes 516. Rear ends of the rails 60 are inserted into the installing space 26. The sliding plates 62 slidably abut against inner surfaces of the side plates 43. The guiding surfaces 67 of the abutting blocks 66 locating at the rear ends of the rails 60 slidably abut against the side plates 43, deforming the tongues 65, until the abutting blocks 66 align with the first locating holes 47. The tongues 65 restore to bias the abutting blocks 66 to being latched in the first locating holes 47. Thereby, the mounting apparatus 100 is mounted to the chassis 200, and the carrier 50 is exposed out of the bracket 40.
FIGS. 7-9 show that, in use, the HDD 300 is placed into the shell 51, with the pins 306 aligning with the installing holes 5132. The HDD 300 is moved down and then rearward. Each pin 306 is received in the receiving portion 5135 through the access portion 5133. Thus, the HDD 300 is supported on the base plate 511. In the above processes of assembling the HDD 300, one of the pins 306 slidably abuts against the abutting plate 72, deforming the abutting plate 72, until the pin 306 is latched in the position hole 75 of the unlocking member 70. The abutting plate 72 restores to abut against the pin 306. The latching member 584 is rotated away from the receiving space 585, until the block 588 is received in the connecting rack 582. The carrier 50 is pushed rearward toward the installing space 26, the guiding surfaces 67 of the abutting blocks 66 at the front ends of the rails 60 slidably abut against inner walls bounding the second locating holes 516, thus deforming the tongues 65. The abutting blocks 66 are detached from the second locating holes 516. The rails 60 are slidably received in the slide slots 515, until they are blocked by the poles 518. The guiding surfaces 67 of the abutting blocks 66 at the rear ends of the rails 60 slidably abut against inner walls bounding the first locating holes 47, deforming the tongues 65, until the abutting blocks 66 are detached from the first locating holes 47. A combination of the rails 60 and the carrier 50 is received in the installing space 26, and the second connector 304 of the HDD 300 is electrically coupled to the first connector 205 of the circuit board 203. The latching member 584 is rotated toward the receiving space 585. The block 588 is latched into the first locating hole 47, and the hook 587 is latched in the latching hole 586 of the connecting rack 582.
To detach the HDD 300 from the mounting apparatus 100, the hook 587 is deformed, until the hook 587 is detached from the latching hole 586. The latching member 584 is rotated away from the receiving space 585, until the block 588 is detached from the first locating hole 47. The carrier 50 is pulled out from the installing space 26. The second connector 304 is detached from the first connector 205. Thus, the carrier 50 can be moved out and exposed from of the bracket 42. The operation plate 74 is pressed through the operation hole 517, deforming the abutting plate 72, until the abutting plate 72 is detached from the pin 306. Thereby, the HDD 300 can be moved upward and detached from the carrier 50.
