Locking mechanism and hard disk assembly

Abstract

A locking mechanism and a hard drive assembly are disclosed. The locking mechanism is used to detachably secure a hard drive. The hard drive has a first groove and a second groove. The first groove is recessed along a first direction, and the second groove is recessed along a second direction. The locking mechanism includes a tray, which includes a top plate, a side plate, a first holding portion, and a second holding portion. The side plate and the top plate are configured to form a receiving cavity for receiving the hard drive. The side plate includes a body portion and a resilient arm, which is located on the side of the body portion opposite to the top plate. The first holding portion is fixed to the top plate and is used to hold the first groove. The second holding portion is fixed to the resilient arm and is used to hold the second groove. The resilient arm is used to deform relative to the body portion to release the second holding portion from its restraint on the second groove.

Claims

1. A locking mechanism for detachably securing a hard disk, the hard disk having a first groove and a second groove, the first groove being recessed along a first direction and the second groove being recessed along a second direction, the improvement being that the locking mechanism includes a tray, the tray comprising: Base plate; roof; The side plate, the top plate, and the side plate are all connected to the bottom plate. The bottom plate, the top plate, and the side plate together form a receiving cavity for accommodating the hard drive. The side plate includes a body and an elastic arm. The body is connected to the top plate, and the elastic arm is located on the side of the body away from the top plate. The bottom plate has a second opening that communicates with the receiving cavity. The second opening is formed by a recess in the surface of the bottom plate near the elastic arm along the first direction. A first retaining part is fixed to the top plate and extends toward the receiving cavity along the first direction. The first retaining part is used to retain the first groove. A second retaining portion is fixed to the elastic arm and extends toward the receiving cavity along the second direction. The second retaining portion is used to retain the second groove. The elastic arm is used to deform relative to the body portion so that the second retaining portion releases its restriction on the second groove.

2. The locking mechanism as described in claim 1, wherein, The locking mechanism further includes a fixing plate located on the side of the side plate away from the receiving cavity. The fixing plate is fixed to the main body, and the elastic arm is exposed to the fixing plate.

3. The locking mechanism as described in claim 2, wherein, The side plate also includes a bending portion that connects the main body and the elastic arm. The bending portion is bent relative to the main body and the elastic arm.

4. The locking mechanism as described in claim 3, wherein, The fixing plate has a first opening, which communicates with the receiving cavity. The elastic arm and the bending portion are both located in the first opening, and the elastic arm is exposed to the fixing plate from the first opening.

5. The locking mechanism as described in claim 2, wherein, The main body has a positioning hole, and the fixing plate has a positioning post, which is received in the positioning hole.

6. The locking mechanism as described in claim 2, wherein, The locking mechanism further includes a fastener that fixes the side plate and the fixing plate; the fixing plate has a receiving groove on its surface facing the side plate, a portion of the side plate is received in the receiving groove, and the fastener passes through the receiving groove and the side plate located in the receiving groove.

7. The locking mechanism as described in claim 1, wherein, The tray also includes a baffle that extends in a third direction from the end of the bottom plate away from the top plate, and the baffle and the side plate are located on the same side of the bottom plate.

8. A hard disk component, improved in that it comprises: The locking mechanism as described in any one of claims 1 to 7; And a hard drive, which is detachably secured in the locking mechanism.

9. The hard disk assembly as described in claim 8, wherein, The hard drive includes a main body and an electrical connection portion. The first groove and the second groove are formed on the main body. The electrical connection portion is connected to the side of the main body opposite to the top plate. The locking mechanism also includes a protrusion portion that extends in a direction opposite to the top plate along the first direction. Along the first direction, the distance from the end of the protrusion portion opposite to the side plate to the surface of the hard drive is greater than the distance from the end of the electrical connection portion opposite to the hard drive to the surface of the hard drive.
