Referring also to FIG. 6, the chassis 10 includes a first sidewall 11 and a second sidewall 12. In one exemplary embodiment, the first sidewall 11 is substantially parallel to the second sidewall 12. The first sidewall 11 defines a fastener opening 112, and a strip 114 is formed on the first sidewall 11 adjacent the fastener opening 112.
The bracket 30 is configured for receiving a disk drive and defines a space 33 for receiving the disk drive. An electromagnetic interference (EMI) shielding component 37 is secured to the bracket 30.
Referring to FIGS. 2-3, the securing component 40 is attached to the bracket 30 and includes two retaining walls 43. In one exemplary embodiment, the retaining walls 43 are substantially parallel to each other. A concave portion 430 is located on each retaining wall 43. A pivot post 431 is located on each concave portion 430. A first end portion 45 is located between the concave portions 430. A receiving slot 451 is defined in the first end portion 45. A through hole 433 is defined in one retaining wall 43. A second end portion 46 is located between the retaining wall 43. A first sliding slot 461 and a plurality of second sliding slots 463 are defined in the second end portion 46. Referring to FIG. 5, a positioning post 421 is located on the securing component 40 at one side of the second end portion 46. In one exemplary embodiment, the positioning post 421 extends in a first direction, which is substantially parallel to the retaining walls 43.
The operating mechanism 50 includes a handle 51 and a sliding component 53.
Two convex portions 52 are located on the handle 51 for engaging with the concave portions 430 of the bracket 40. A pivot hole 515 is defined in each convex portion 52 for receiving the pivot post 431 of the bracket 40. A cutout 511 is defined in each convex portion 52, and a locking protrusion 513 is located on each convex portion 52. A retaining post 517 is located on one side of the handle 51. A latch portion 519 with a slanted surface is located on the handle 51, and the slanted surface faces the securing component 40.
A recess 533 is defined in the sliding component 53, and a plurality of hooks 537 is located on the sliding component 53. A through opening 5331 is defined in the recess 533. A blocking tab 5334 with a receiving hole 5335 extends from an edge of the through opening 5331. A positioning block 535 is located on the sliding component 53, and a positioning tab 5351 (shown in FIG. 5) is located on the sliding component 53. A holding hole 531 is defined in the sliding component 53 at a top end. In one exemplary embodiment, the positioning tab 5351 extends in a second direction, which is substantially parallel to the retaining walls 43 of the securing component 40.
The latch mechanism 100 includes a latch post 60 and a pusher 70. The latch post 60 includes a first portion 61 and a second portion 63, that is smaller than the first portion 61. In one exemplary embodiment, the first portion 61 and the second portion 63 are cylinder, and a diameter of the first portion 61 is greater than a diameter of the second portion 63. A plurality of ribs 631 is located on the second portion 63 and is connected the first portion 61. The pusher 70 includes a main body 71 and a grip portion 73. The main body 71 defines a through hole 711, which has a size smaller than the size of the first portion 61 of the latch post 60, but greater than the size of the second portion 63. In one exemplary embodiment, the through hole 711 is circular, and has a diameter smaller than the diameter of the first portion 61, but greater than the diameter of the second portion 63. The main body 71 can be secured to the latch post 70 substantially adjacent to the first portion 61, by the ribs 631 are securely received in the through hole 711. The grip portion 73 of the pusher 70 has veins 731 at two sides for easily gripping the grip portion 73 of the pusher 70.
Referring also to FIGS. 4-5, in assembly, the securing component 40 is secured to the bracket 30 with fasteners, such as screws of bolts. The EMI shielding component 37 is secured between the bracket 30 and the securing component 40. The pivot posts 431 of the securing component 40 is inserted in the pivot holes 515 of the handle 51, and the convex portions 52 are engaged with the concave portions 430. The handle 51 is therefore rotatable about the pivot posts 431 of the securing component 40. A first spring 80 is secured between the handle 51 and the securing component 40. One end of the first spring 80 is received in the receiving slot 451 of the securing component 40, and the other end thereof is mounted on the retaining post 517 of the handle 51.
The latch post 60 is inserted in holding hole 531. The first portion 61 of the latch post 60 is engaged in the through hole 711 of the pusher 70, and then it is inserted in the receiving hole 5335 of the blocking tab 5334 of the sliding component 53. The latch post 60 is therefore secured to the sliding component 53. In one exemplary embodiment, the latch post 60 is positioned in a vertical position.
The positioning block 535 and the first hooks 537 are slidably engaged in the first sliding slot 461 and the second sliding slots 463. Therefore, the sliding component 53 is slidable on the second end portion 46. A second spring 90 is secured between the positioning block 535 and the securing component 40. One end of the second spring 90 is mounted on the positioning tab 5351 of the positioning block 535, and the other end thereof is mounted on the positioning post 421 of the securing component 40.
The sliding component 53 is slidable between a first position and a second position. In the first position, the second spring 90 is resiliently deformed and urges the positioning block 535 and the first hooks 537 to adjoin the edges of the first sliding slot 461 and the second sliding slots 463. The first portion 61 of the latch post 60 correspond to the through hole 433 of the securing component 40. In the second position, the second spring 90 is further resiliently deformed, and the positioning block 535 and the first hooks 537 slide away from the edges of the first sliding slot 461 and the second sliding slots 463. In one exemplary embodiment, the latch post 60 is substantially perpendicular to the retaining walls 43.
Referring also to FIGS. 4-6, in use, the handle 51 is rotatable between an open position (shown in FIG. 6) and a close position (shown in FIGS. 4-5) about the pivot posts 431 of the securing component 40. In the open position, the latch portion 519 is disengaged away from the sliding component 53, the first spring 80 is in an original state, and the handle 51 is rotated away from the securing component 40. In the close position, the latch portion 519 is engaged with the sliding component 53, and the first spring 80 is resiliently deformed.
When the handle 51 is rotated from the open position to the close position, the slanted surface of the latch portion 519 presses and slides the sliding component 53 from the first position to the second position. The first spring 80 is resiliently deformed. When the sliding component 53 is in the second position, the latch portion 519 can pass across the sliding component 53. The second spring 90 rebounds to slide the sliding component 53 from the second position to the first position, to engage the sliding component 53 with the latch portion 519. The handle 51 is therefore positioned in the close position.
To release the handle 51 from the sliding component 53, the sliding component 53 is slid from the first position to the second position, to disengage the latch portion 519 from the sliding component 53. The first spring 80 rebounds to rotate the handle 51 away from the securing component 40.
When the sliding component 53 is in the first position, the latch post 60 corresponds to the through hole 433 of the securing component 40. The latch post 60 is slid by the grip portion 73 of the pusher 70, to insert the first portion 61 of the latch post 60 in the through hole 433 of the securing component 40. The sliding component 53 is thereby prevented from sliding from the first position to the second position. When sliding of the sliding component 53 is desired, the latch post 60 is slid by the grip portion 73 of the pusher 70 to disengage the first portion 61 from the through hole 433.
In one exemplary embodiment, since the size, such as the diameter of the through hole 433 of the securing component 40 is slightly smaller than the size, such as the diameter of the first portion 61 of the latch post 60, the first portion 61 can be securely engaged in the through hole 433 of the securing component 40. The first portion 61 cannot disengaged from the through hole 433 without a predetermined force applied to the grip portion 73 of the grip portion 73 of the pusher 70.
In assembling the bracket 30 to the chassis 10, the handle 51 is positioned in the open position. The bracket 30 is inserted in a space between the first sidewall 11 and the second sidewall 12 of the chassis 10. When the locking protrusion 513 of the handle 51 corresponds to the fastener opening 112, the handle 51 is rotated from the open position to the close position. The locking protrusion 513 is engaged in the fastener opening 112, and the strip 114 is received in the cutout 511 of the handle 51. Therefore, the bracket 30 is secured in the chassis 10.
In disassembly of the bracket 30, the handle 51 is rotated from the close position to the open position. The locking protrusion 513 is disengaged from the fastener opening 112, and the strip 114 is disengaged from the cutout 511 of the handle 51. The bracket 30 can be thus removed out from the chassis 10.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
