Each mounting groove 352 extends transversely through the flange 351.
Referring to FIG. 5, each latching unit 50 includes a fixing tray 60, a fastening member 600, a sliding member 70, a spring 700, a resisting member 80, a substantially Z-shaped resilient member 800, and a pushing member 90.
The fixing tray 60 includes a side panel 63, a top panel 61 and a bottom panel 62 correspondingly extending from a top side and a bottom side of the side panel 63, and a fixing wall 64 connected to corresponding first ends of the side panel 63, the top panel 61, and the bottom panel 62. A protrusion 611 protrudes from a middle of the top panel 61. A fixing post 602 extends towards the fixing wall 64 from a first end of the protrusion 611, parallel to the top panel 61. A first fixing peg 601 and a second fixing peg 603 protrude from the first end and a second end opposite to the first end of the top panel 61. A third fixing peg 604 extends from the bottom panel 62, in alignment with the first fixing peg 601. Two aligned shaft holes 610, 620 are correspondingly defined in the second ends of the top panel 61 and the bottom panel 62. An opening 640 is defined in the fixing wall 64. The top panel 61, the side panel 63, and the bottom panel 62 together form a holding space 65 for receiving the sliding member 70. Two parallel fixing boards 66 are formed in the holding space 65, parallel to the fixing wall 64 and connected to the protrusion 611 and the bottom panel 62. A sliding slot 660 is defined in each fixing board 66, and extends to the side panel 63. A clamping protrusion 662 extends from a side away from the other fixing board 66 of each fixing board 66, parallel to the fixing wall 64. A resisting board 67 defining a through hole 670 is formed in the holding space 65, and located between the first fixing peg 601 and the shaft hole 610.
The sliding member 70 includes a sliding body 71, a pushing portion 72 extending from a first end of the sliding body 71, and a mounting shaft 73 extending from a second end opposite to the first end of the sliding body 71. A mounting groove 74 is defined in the sliding body 71, adjacent to the mounting shaft 73. The mounting groove 74 includes an angled surface 741, away from the mounting shaft 73.
The resisting member 80 includes a main body 81, and an angled rim 82 extending from one side of the main body 81. The main body 81 includes an angled guiding surface 810, and the angled rim 82 includes a resisting surface 820.
The fastening member 600 includes a cover 605 and two fixing flanges 606 extending from opposite ends of the cover 605. Each fixing flange 606 defines a fixing hole 607, for fixing the fastening member 600 to the fixing boards 66 of the fixing tray 60.
The pushing member 90 includes a pivoting portion 91, and a first pushing portion 92 and second pushing portion 93 extending from opposite sides of the pivoting portion 91. Two pivoting shafts 94 extend from a top and a bottom of the pivoting portion 91, respectively.
During assembly of each latching unit 50, the spring 700 fits about the mounting shaft 73 of the sliding member 70. The sliding member 70 is received in the holding space 65 of the fixing tray 60, with the mounting shaft 73 together with the spring 700 passing through the sliding slots 660 of the fixing tray 60, and the mounting shaft 73 passing through the through hole 670 of the fixing tray 60. After the sliding member 70 is received in the holding space 65, the pushing portion 72 of the sliding member 70 is slidably engaged in the opening 640 of the fixing tray 60. Accordingly, opposite ends of the spring 700 resist the sliding body 71 of the sliding member 70 and the resisting board 67 of the fixing tray 60. The mounting groove 74 of the sliding member 70 is located between the fixing boards 66. The angled rim 82 of the resisting member 80 is received in the mounting groove 74 of the sliding member 70. Therefore, the resisting surface 820 of the angled rim 82 resists the angled surface 741 of the mounting groove 74, and opposite sidewalls of the main body 81 of the resisting member 80 abut the fixing boards 66 respectively. The resilient member 800 is received in the holding space 65, with two ends of the resilient member 800 resisting the protrusion 611 of the fixing tray 60 and a top of the main body 81. The fixing holes 607 of the fastening member 600 engage the clamping protrusions 662 of the fixing boards 66, correspondingly. The fastening member 600 is thereby fixed to the fixing tray 60, and the cover 605 of the fastening member 600 resists the main body 81. The pivoting shafts 94 of the pushing member 90 pivotally engage the shaft holes 610 and 620 of the fixing tray 60, correspondingly. The pushing member 90 is thus pivotally mounted to the fixing tray 60, with the second pushing portion 93 away from the side panel 63 of the fixing tray 60.
Referring to FIG. 3, in assembly of each latching unit 50 to the bracket 30, the pushing portion 72 of the latching unit 50 is retracted into the holding space 65 of the latching unit 50, such that the spring 700 is deformed. The latching unit 50 is mounted to an optional sliding groove 332 of the first side plate 33 of the bracket 30, and situated between the first and fourth clipping portions 41 and 44, with the holding space 65 facing the first side plate 33. Thus, the pushing member 90 faces the resisting tab 334 of the bracket 30. The fixing portion 45 of the bracket 30 is received in the holding space 65. The pushing portion 72 is in alignment with one of the through holes 333 of the bracket 30. The pushing portion 72 is released, and the spring 700 restores to drive the pushing portion 72 through the opening 640 of the fixing tray 60 and one of the through holes 333 in that order. When the latching unit 50 is moved towards the mounting tab 331 of the bracket 30, the first end of the protrusion 611 of the latching unit 50 is moved beyond the guiding surface 451 of the fixing portion 45. Accordingly, the first end of the protrusion 611 resists the resisting end 452 of the fixing portion 45, and the fixing post 602 of the latching unit 50 is clamped in the second clipping portion 42 of the bracket 30. Correspondingly, the first fixing peg 601, the second fixing peg 603, and the third fixing peg 604 of the latching unit 50 are clamped in the first, third, and fourth clipping portions 41, 43, and 44 of the bracket 30, respectively. Thus, the second portion 93 of the pushing member 90 is received in the corresponding receiving cutout 335 of the resisting tab 334 of the bracket 30.
Referring to FIG. 3, in use, each data storage device 100 is pushed into the bracket 30, and moved towards the resisting tab 334 of the bracket 30, with the first and second posts 101, 102 of the first sidewall 110 of the data storage device 100 sliding in the corresponding sliding groove 332 of the first side plate 33 of the bracket 30, and the plurality of second posts 102 of the second sidewall 120 of the data storage device 100 sliding in the corresponding mounting groove 352 of the second side plate 35 of the bracket 30. When the first post 101 is moved to resist the guiding surface 810 of the resisting member 80 of the latching unit 50, the resisting member 80 is moved into the holding space 65 of the latching unit 50. As a result, the resilient member 800 of the latching unit 50 is deformed. The first post 101 is moved over the guiding surface 810, the elasticity of the resilient member 800 moves the resisting member 80 to the outside of the holding space 65 along a direction indicated by a vertical arrowhead D, to prevent the data storage device 100 from disengaging from the bracket 30, as shown in FIG. 6 and FIG. 7. The pushing portion 72 moves out along a direction indicated by a horizontal arrowhead C.
Referring to FIG. 8 and FIG. 9, in removal of each data storage device 100 from the bracket 30, the pushing portion 72 of the latching unit 50 is slid in the holding space 65 of the fixing tray 60 of the latching unit 50 along an arrowhead direction A, whereby a distal end of the mounting shaft 73 is moved to the first pushing portion 92 of the pushing member 90 of the latching unit 50. As a result, the pushing member 90 is rotated, as is, in turn, the second pushing portion 94, to eject the data storage device 100 from the bracket 30. Commensurately, the angled surface 741 of the sliding member 70 resists the resisting surface 820 of the resisting member 80, such that the resisting member 80 is moved into the holding space 65 of the latching unit 50 along an arrowhead direction B. The data storage device 100 is thus readily removed from the bracket 30.
In other embodiments, the mounting tab 331 and the resisting tab 334 of the first side plate 33 of the bracket 30 may be omitted, as may the fixing flange 354 and the flange 351 of the second side plate 35. The guiding surface 810 of the resisting member 80 may also be omitted.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and they will be apparent that various changes may be made thereto without departing from the spirit and scope of the description or sacrificing all of their material advantages, the examples hereinbefore described merely being exemplary embodiment.
