Abstract

A disk drive mounting assembly includes a chassis (16), a first receiving cage (20), a mounting bracket (50) and a second receiving cage (60). The disk drive (10) comprises two pairs of sliding posts (12). The first cage for receiving the disk drive is generally U-shaped and has two side walls (23, 24). Each side wall defines a pair of slots (26, 32) for accommodating the sliding posts of the disk drive. The mounting bracket (50) pivotably attached to the first cage includes a pressing body (52) and a pair of fixing arms (54) depending from the pressing body. Each fixing arm defines a fixing cutout (56) for restraining the sliding posts. The second cage is attached to the chassis on the mounting bracket to prevent the disk drive from moving in vertical directions.

Claims

1. A mounting assembly for mounting a disk drive having a plurality of sliding members in a computer chassis, the mounting assembly comprising:

a first receiving cage adapted for being attached in the chassis, the cage comprising a base and two side walls, each of the side walls defining a plurality of slots for receiving corresponding sliding members of the disk drive;

a mounting bracket pivotally mounted to the first receiving cage, the mounting bracket comprising a pressing body and two fixing arms respectively depending from the pressing body, each of the fixing arms defining a cutout receiving a corresponding sliding member of the disk drive;

wherein the mounting bracket is pivotable between a first position in which the sliding members are engaged in the corresponding cutouts and the disk drive is located in a locked position, and a second position in which the sliding members are released from the corresponding cutouts and the disk drive is located in an unlocked position.

2. The mounting assembly as claimed in claim 1, further comprising a second receiving cage located on the pressing body of the mounting bracket for preventing the disk drive from moving from the first position.

3. The mounting assembly as claimed in claim 1, wherein the slots comprise a pair of rear slots located in rear portions of the side walls of the first receiving cage respectively, and each of the rear slots is generally dogleg-shaped, comprising a slanted guiding portion and a sliding portion parallel to the base.

4. The mounting assembly as claimed in claim 1, wherein the slots comprise a pair of front slots located in front portions of the side walls of the first receiving cage respectively, and each of the front slots is linear and parallel to the base.

5. The mounting assembly as claimed in claim 1, wherein the slots comprise a pair of front slots located in front portions of the side walls of the first receiving cage respectively, and each of the front slots is generally dogleg-shaped, comprising a slanted guiding portion and a sliding portion parallel to the base.

6. The mounting assembly as claimed in claim 1, wherein each of the side walls of the first receiving cage forms a stop at a rear end thereof, and the mounting bracket abuts the stops in the unlocked position.

7. The mounting assembly as claimed in claim 6, wherein each of fixing arms of the mounting bracket defines a pivot hole, and each of the side walls of the first receiving cage forms a pivot located between the stop and a rearmost one of the slots, the pivots being pivotably received in the corresponding pivot holes.

8. A computer case comprising:

a chassis;

a first receiving cage attached in the chassis, the first receiving cage comprising two side walls, each of the side walls defining a plurality of slots;

a disk drive received in the first receiving cage, the disk drive comprising a plurality of sliding members received in corresponding slots of the first receiving cage; and

a mounting bracket pivotably attached to the first receiving cage, the mounting bracket comprising a pressing body and two fixing arms respectively depending from opposite ends of the pressing body, each of the fixing arms defining a cutout engagingly receiving a corresponding sliding member of the disk drive thereby securing the disk drive to the first receiving cage.

9. The computer case as claimed in the claim 8, wherein each of the fixing arms forms a first blocking portion and a second blocking portion at opposite sides of the cutout respectively.

10. The computer case as claimed in the claim 9, wherein each of the second blocking portions defines a pivot hole, and each of the side walls of the first receiving cage forms a pivot, the pivots being pivotably engaged in the corresponding pivot holes thereby pivotably connecting the mounting bracket to the first receiving cage.

11. The computer case as claimed in the claim 8, further comprising a second receiving cage attached to the chassis and located on the pressing body of the mounting bracket, for retaining the disk drive in the chassis.

12. The computer case as claimed in the claim 8, wherein the slots comprise a pair of rear slots located in rear portions of the side walls of the first receiving cage respectively, and each of the rear slots is generally dogleg-shaped, comprising a slanted guiding portion and a sliding portion generally parallel to the first receiving cage.

13. The computer case as claimed in the claim 8, wherein the slots comprise a pair of front slots located in front portions of the side walls of the first receiving cage respectively, and each of the front slots is linear and generally parallel to the first receiving cage.

14. The computer case as claimed in the claim 8, wherein the slots comprise a pair of front slots located in front portions of the side walls of the first receiving cage respectively, and each of the front slots is generally dogleg-shaped, comprising a slanted guiding portion and a sliding portion generally parallel to the first receiving cage.

15. A computer casing assembly comprising:

a chassis including a bottom panel;

a first cage fixed to the bottom panel;

a disk drive generally horizontally sliding into and received in the cage;

a mounting bracket pivotally mounted on the first cage and prohibiting said disk drive from withdrawal therefrom when said mounting bracket is in a fixed position; and

a second cage pivotally mounted to the chassis and above said first cage;

wherein

said second cage retains said mounting bracket in the fixed position when said second cage is located in a final assembling position.

16. The assembly as claimed in claim 15, wherein a direction of a pivotal axis of said mounting bracket is perpendicular to that of another pivotal axis of said second cage.

17. The assembly as claimed in claim 16, wherein a sliding direction of said disk drive relative to the first cage is parallel to the direction of the pivotal axis of the second cage.
