MOUNTING APPARATUS FOR HARD DISK DRIVE

Abstract

An apparatus for mounting a hard disk drive (HDD) includes a base board and a casing for receiving the HDD. A number of engaging portions and a holding portion protrude from the base board. The holding portion defines a through hole. The casing includes a bottom wall defining a number of fixing holes and a front wall perpendicular to the bottom wall. Each fixing hole includes a first hole and a second hole communicating with the first hole. A width of the first hole is greater than a width of the second hole. A fixing member is mounted on an outer surface of the front wall. The engaging portions extend through the first holes, respectively. The casing is then slid toward the holding portion, until the fixing member engages in the through hole and the engaging portions engage in the corresponding second holes.

DETAILED DESCRIPTION

The disclosure, including the accompanying drawings, is illustrated by way of example and not by way of limitation. 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, an embodiment of a mounting apparatus is provided for mounting a hard disk drive (HDD) 10. The mounting apparatus includes a base board 21 of a chassis 20, a casing 30 for receiving the HDD 10, and a fixing member 40 mounted to an outer surface of the casing 30.

The base board 21 forms three substantially columnar engaging portions 22 arranged in a triangle. A bridge-shaped holding portion 24 defining a through hole 240 in a top surface protrudes up from the base board 21, in front of the engaging portions 22. The holding portion 24 includes a guiding surface 242 extending slantingly down from the top of the holding portion 24 toward the engaging portions 22.

Referring to FIG. 4, each engaging portion 22 includes a neck 220 extending perpendicularly from the base board 21, and a head 222 extending from a top end of the neck 220 opposite to the base board 21. The diameter of the head 222 is greater than the diameter of the neck 220.

The casing 30 includes a bottom wall 32 and a front wall 340 extending perpendicularly from a front end of the bottom wall 32. The bottom wall 32 defines a depressed portion 325 in a center. Sidewalls 300 bounding the depressed portion 325 define a plurality of vents 302. Two supporting portions 321 each define a through hole 322 protruding from the bottom wall 32 adjacent to each opposite sidewalls 300 of the depressed portion 325. A bottom wall 327 of the depressed portion 325 defines three fixing holes 324 corresponding to the engaging portions 22. Each fixing hole 324 includes a first hole 326 adjacent to the front wall 340 and a second hole 328 communicating with the first hole 326 and positioned away from the front wall 340.

The width of the first hole 326 is greater than the width of the second hole 328. A tab 342 extends perpendicularly and out from the front wall 340, and defines a through hole 344.

Referring to FIG. 2, in one embodiment, the fixing member is a thumbscrew. The fixing member 40 includes a movable assembly 42, a spring 422, a block 44, a blocking portion 46, and a spacer 48.

The movable assembly 42 includes a head 420 defining a threaded hole 421 and a pole 424. The pole 424 includes a middle portion 425, a threaded portion 426 connected to a first end of the middle portion 425, and an inserting portion 428 connected to a second end of the middle portion 425 opposite to the threaded portion 426. The diameter of the inserting portion 428 is greater than the diameter of the spring 422. The diameter of the spring 422 is greater than the diameter of the middle portion 425.

The block 44 defines a threaded hole 440 extending through a bottom surface of the block 44, and a through hole 442 communicating with the threaded hole 440 and extending through a top surface of the block 44 opposite to the bottom surface. The diameter of the threaded hole 440 is greater than the diameter of the through hole 442. A step 446 is formed at a junction of the through hole 442 and the threaded hole 440.

The blocking portion 46 includes a blocking piece 460, an extension portion 462 extending from a top of the blocking piece 460, and a threaded portion 464 extending from a distal end of the extension portion 462 opposite to the blocking piece 460. The blocking portion 46 defines a slot 466 extending through the blocking piece 460, the extension portion 462, and the threaded portion 464.

Referring to FIGS. 3 and 6, in assembly, the threaded portion 426 extends through the spring 422, the threaded hole 440, the through hole 442, and then engaged in the threaded hole 421 to fix the pole 424 to the head 420. The movable assembly 42 is movable relative to the block 44. The spring 422 is received in the slot 466 and sandwiched between the step 446 and the inserting portion 428. A distal end of the inserting portion 428 opposite to the threaded portion 426 extends out of the threaded hole 440. The threaded portion 464 extends through the through hole 344 from a bottom of the tab 342 and the spacer 48, and then engages in the threaded hole 440 until the blocking piece 460 is abutted against a bottom surface of the tab 342. The extension portion 462 is received in the through hole 344. The distal end of the inserting portion 428 extends out of the slot 466.

The HDD 10 is supported and fixed on the supporting portions 321. The casing 30 with the HDD 10 is manipulated down towards the base board 21. The engaging portions 22 extend into the first holes 326, respectively. The casing 30 is then moved towards the holding portion 24. The distal end of the inserting portion 428 abuts against the guiding surface 242 and slides toward the through hole 240. The spring 422 is deformed, and the inserting portion 428 is retracted into the slot 466 gradually while the distal end of the inserting portion 428 slides on the guiding surface 242. When the necks 220 enter the corresponding second holes 328, the inserting portion 428 is aligned with the through hole 240. The spring 422 is restored and biases the inserting portion 428 to be inserted into the through hole 240, thereby fixing the casing 30 on the base board 21. The heads 222 are blocked by the bottom wall of the depressed portion 325.

In disengaging the casing 30 from the base board 21, the head 420 is pulled away from the block 44, to disengage the inserting portion 428 from the through hole 240. The casing 30 is then readily slid away from the holding portion 24, so that the necks 220 may enter the corresponding first holes 326 again.

Because the supporting portions 321 protrude from the bottom wall 32, the bottom of the HDD 10 is never in contact with the bottom wall 327 of the depressed portion 325. The vents 302 defined in the sidewalls 300 of the depressed portion 325 can rapidly dissipate heat generated by the HDD 10.

It is believed that the present embodiments and their advantages will be understood from the foregoing description, and various changes may be made thereto without departing from the spirit and scope of the description or sacrificing all of their material advantages.
