Referring to fig. 5 to 7, the following is an operation description of the hard disk tray of the present invention: the operation portion 511 of the switch 51 can be pressed by a user, and here, the straight section 217a of the locking slot 217 is a space for allowing the locking portion 512 to move in the front-back direction D, and pivots to abut against the side edges of the first wall 211 and the second wall 212 with the rotating shaft portion 514 as an axis, so that the protrusion 511a of the operation portion 511 is separated from the groove 41 of the handle 4, and the engagement relationship between the switch 51 and the handle 4 is released, so that the handle 4 can pivot in a direction away from the base 2. In the embodiment, a spring (not shown) is disposed in the rotating shaft sleeve of the handle 4 pivoted to the base body 21, and when the switch member 51 is engaged with the handle 4, the spring is in a compressed state, so that when the protrusion 511a is separated from the groove 41, the elastic restoring force of the spring will automatically pivot the handle 4 in a direction away from the base 2, but in other embodiments without the spring, the user can pull out the handle 4 by himself after pressing the switch member 51, and can also pivot the handle 4 in a direction away from the base 2. By the arrangement of the elastic member 52, during the process that the switch member 51 is operated and pivoted to abut against the first wall 211 and the second wall 212, the elastic member 52 is compressed to provide a restoring force to the switch member 51 so as to return the switch member 51 to the non-operated position.

Referring to fig. 8 and 9, the switch element 51 can be further pushed by the user to push the operation portion 511 to make the rotation shaft portion 514 move toward the engaging element 22 along the extending direction of the groove 216, meanwhile, the transverse section 217b of the locking slot 217 is a space allowing the locking portion 512 to move transversely, and by the mutual inclined fit between the first abutting surface 222 of the engaging member 22 and the second abutting surface 515a of the pushing portion 515 of the switch member 51, when the pushing portion 515 pushes the engaging member 22, a force in a direction away from the base 2 is applied to the engaging member 22 to generate a moment on a fulcrum (the engaging member 22 is connected to one end of the connecting beam 214), so that the engaging member 22 pivots in a first pivoting direction R1 (counterclockwise in the drawing) to drive the hook 221 to separate from the opening groove 312a of the first side arm 31 of the frame 3, so as to release the locking relationship between the engaging member 22 and the first side arm 31, as shown in fig. 8. In this way, the first side arm 31 can move between a contact position and a release position relative to the hard disk 1, that is, the first section 311 of the first side arm 31 can move relative to the slot 213a, so that the first side arm 31 can move between the contact position and the release position relative to the hard disk 1. In the abutting position, the first side arm 31 is firmly abutted against the side 11 of the hard disk 1, that is, the positioning blocks on the first side arm 31 respectively and correspondingly extend into the mounting holes correspondingly disposed on the corresponding side 11, and the first side arm 31 is engaged with the engaging member 22, as shown in fig. 8, a user can pull the first side arm 31 through the portion of the slot 213a from the slot 213a in a direction away from the base body 21, so that the distance between the second section 312 of the first side arm 31 and the second side arm 32 is increased, and the first side arm 31 is no longer firmly abutted against the side 11 of the hard disk 1 to reach the releasing position in a linkage manner, that is, the positioning blocks on the first side arm 31 do not extend into the mounting holes correspondingly disposed on the corresponding side 11, and the first side arm 31 is not engaged with the engaging member 22, so that the hard disk 1 can be pulled out from the frame 3, to facilitate the user's removal of the hard disk 1, as shown in fig. 9. Similarly, by the arrangement of the elastic element 52, when the switch element 51 is operated to move towards the extending direction of the grooves 216, the elastic element 52 is compressed to provide a restoring force to the switch element 51 so as to return the switch element 51 to a return position which is not operated, and after the switch element 51 returns to the return position, the engaging element 22 can return to an initial position engaging with the first side arm 31 due to its own elastic restoring force, so that the engaging element 22 of the present embodiment acts like an elastic arm, and can be pushed to release the engaging state with the first side arm 31, and when the force is released, the engaging state with the first side arm 31 is restored. In other embodiments, the elastic member 52 may not be provided, but the user needs to manually return the switch member 51 to the restoring position after operating the switch member 51.

It should be noted that, in other embodiments, the first abutting surface 222 of the engaging element 22 and the second abutting surface 515a of the pushing portion 515 of the switch element 51 do not need to be inclined, as long as the first abutting surface 222 of the engaging element 22 faces the pushing portion 515, the pushing portion 515 applies a force to the engaging element 22 in a direction away from the base 2 when pushing the engaging element 22, so as to generate a moment on a fulcrum (one end of the engaging element 22 connected to the connecting beam 214) to pivot the engaging element 22 in the first pivot direction R1, and if the extending direction of the groove 216 is inclined to the extending direction of the base body 21 as in the other embodiments, the above-mentioned effects can be achieved by the mutual engagement of the first abutting surface 222 of the engaging element 22 and the second abutting surface 515a of the pushing portion 515a of the switch element 51. In another embodiment, when the first side arm 31 of the frame 3 is engaged with the engaging member 22, the first side arm 31 has been elastically deformed, so that when the switch 51 is operated to release the engaging relationship between the engaging member 22 and the first side arm 31 of the frame 3, the elastic restoring force of the first side arm 31 will move the first side arm 31 away from the base body 21. In yet another embodiment, after the switch 51 is operated to release the engaging member 22 from the engaging relationship with the first side arm 31 of the frame 3, the first side arm 31 can be elastically deformed by an external force (e.g. a user pulls the first side arm with a hand) to move relative to the hard disk 1 in a direction away from the base body 21, and when the external force is released, the elastic restoring force of the first side arm 31 will move the first side arm 31 in the direction of the hard disk 1 to return to a position where the first side arm 31 is engaged with the engaging member 22.

Referring to fig. 10 to 12, a second embodiment of the hard disk tray of the present invention is substantially the same as the first embodiment, except that the extending direction of the grooves 216 is perpendicular to the extending direction of the base body 21 and extends toward the frame 3, the engaging member 22 is pivoted between the stoppers 215 and the abutting portion of the pushing portion 515 of the switch member 51 is located between the frame 3 and the switch member 51, the user can still operate the operating portion 511 of the switch member 51 in a pressing manner to release the engaging relationship between the switch member 51 and the handle 4, but when the user pushes the operating portion 511 to move the rotating shaft portions 514 toward the engaging member 22 along the extending direction of the grooves 216, the pushing portion 515 directly pushes the engaging member 22 to apply a force toward the first side arm 31, so that the engaging member 22 pivots in a second opening groove R2 (clockwise in the drawing) to drive the hook 221 to separate from the 312a of the first side arm 31, the engagement between the engaging piece 22 and the first side arm 31 can be released in the same manner as shown in fig. 10.

It should be noted that, in other embodiments, the base body 21 may not include the connecting wall 213, and the first wall 211 and the second wall 212 may be supported and connected by other structures, such as a plurality of connecting beams 214, to the first wall 211 and the second wall 212, which still achieves the effect of the present invention.

As described above, the hard disk tray of the present invention can be operated by the switch 51 of the operation unit 5 to pivot about the rotation shaft 514 and to move toward the engaging element 22 along the extending direction of the groove 216, so that the switch 51 has the function of releasing the engaging relationship between the switch 51 and the handle 4, and the function of pushing the engaging element 22 to pivot to release the engaging relationship between the engaging element 22 and the first side arm 31 of the frame 3, and the first side arm 31 can move away from the base body 21, so that the distance between the first side arm 31 and the second side arm 32 is increased, and the hard disk 1 can be conveniently taken out. Such a design is convenient for the user to operate, so as to achieve the purpose of the present invention.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
