Carrier for hard disk drive

1. A carrier for a hard disk drive comprising:

a frame, the frame comprising a first connecting wall and two coupling walls extending from opposite edges of the first connecting wall and defining a first space configured to accommodate a first hard disk drive;

an adjusting mechanism rotatably coupled to the frame and comprising an installation portion and a coupling portion extending from each of two ends of the installation portion, and each coupling portion being rotatably coupled to a coupling wall, the adjusting mechanism transitionable between:

(i) a first configuration in which the adjusting mechanism is located outside the first space defined by the frame, the installation portion being parallel to the first connecting wall, and configured to receive the first hard disk drive between the first connecting wall and the installation portion; and

(ii) a second configuration in which the adjusting mechanism is located inside the first space, the installation portion being parallel to the first connecting wall, and the first connecting wall, the two coupling walls, and the installation portion cooperatively defining a second space configured to accommodate a second hard disk drive different from the first hard disk drive.

2. The carrier of claim 1 , wherein the adjusting mechanism comprises an installing portion configured to install the first hard disk drive or the second hard disk drive, and two coupling portions extending from two opposite ends of the installing portion, the two coupling portions being rotatably coupled to the frame.

3. The carrier of claim 2 , wherein the frame comprises two opposite coupling walls and a connecting wall connecting the two coupling walls, and the two coupling portions of the adjusting mechanism are rotatably coupled to the two coupling walls respectively.

4. The carrier of claim 3 , wherein the two coupling walls each define a through hole, the two coupling portions each define a through aperture, and two pivots are received in corresponding through holes and corresponding through apertures to rotatably couple the coupling walls with the coupling portions.

5. The carrier of claim 4 , wherein the two coupling walls each define a recess, the coupling portions being received in the recesses of the coupling walls respectively.

6. The carrier of claim 5 , wherein the connecting wall defines a receiving room receiving the installing portion of the adjusting mechanism.

7. The carrier of claim 6 , wherein the adjusting mechanism in the first configuration is symmetrical to the adjusting mechanism in the second configuration about a line where the two pivots are located.

8. The carrier of claim 7 , wherein each of the coupling walls form two latches at two opposite sides of the through hole, each of the coupling portions defining an engaging hole, and each coupling wall having one of the latches engaging in a corresponding engaging hole to latch the adjusting mechanism in the first configuration or the second configuration.

9. The carrier of claim 3 , wherein the adjusting mechanism is prevented by the coupling walls from rotating more than 180 degrees.

10. The carrier of claim 1 , wherein the adjusting mechanism defines two installing holes configured to install the first hard disk drive and the second hard disk drive.

11. A carrier for a hard disk drive, the carrier comprising:

a frame comprising a first connecting wall and two coupling walls extending from opposite edges of the first connecting wall and at least partially defining a hard disk receiving space and wherein the receiving space is variably configurable to accommodate differently configured hard disk drives; and

an adjusting mechanism pivotably coupled to the frame and comprising an installation portion and a coupling portion extending from each of two ends of the installation portion, each coupling portion being rotatably coupled to a coupling wall, the adjusting mechanism transitionable between:

(i) a first configuration in which the installation portion is parallel to the first connecting wall, and the first connecting wall, the two coupling walls, and the installation portion cooperatively defining a first hard disk drive receiving space, and

(ii) a second configuration in which the adjusting mechanism is located within the first hard disk drive receiving space, the installation portion being parallel to the first connecting wall, and the first connecting wall, the two coupling walls, and the installation portion cooperatively defining a second hard disk drive receiving space different from the first hard disk drive receiving space.
