Abstract:
A tray assembly for mounting a disk drive includes an enclosure; and a tray mounted to the enclosure. The tray includes a tray body configured to receive the disk drive, a handle pivotably mounted to the tray body, and a securing member pivotably mounted to the tray body. The handle is configured to secure the tray body to the enclosure as the handle rotates. The securing member is configured to engage the handle as the tray body is in a secured state.

Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates to disk drive assemblies. 
     2. Description of Related Art 
     A typical personal computer includes data storage devices such as a hard disk drive (HDD), a floppy disk drive, and a compact disc-read only memory (CD-ROM) drive. Conventionally, the data storage devices are attached to a chassis of a computer enclosure using screws. A tool such as a screwdriver is used to fasten the screws, and to unfasten the screws when removing the data storage devices. Such operations are laborious and time-consuming. Furthermore, unintentional accidents may occur during operations (i.e. operator dropping tools and screws). When this happens, other internal components of the computer are liable to be damaged.

     DETAILED DESCRIPTION 
     The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one. 
     Referring to  FIGS. 1 and 2 , a tray assembly includes an enclosure  10 , a disk drive  20 , and a tray  30  for receiving the disk drive  20 . 
     The enclosure  10  includes a bottom wall  11  and a side wall  12 . The bottom wall  11  includes two mounting portions  111 . Each mounting portion  111  includes a first protrusion  112 . The side wall  12  includes two second protrusions  121 . 
     Two mounting holes  21  are respectively defined in opposite sides of the disk drive  20 . The disk drive  20  includes an inserting terminal  22  at the rear side thereof. 
     The tray  30  includes a tray body  40 , a handle  50 , and two securing members  60 . The tray body  40  includes a bottom panel  41  parallel to the bottom wall  11  and two side panels  42  extending from opposite sides of the bottom panel  41 . Two mounting openings  421  are defined in a connecting portion between each side panel  42  and the bottom panel  41 . Each mounting opening  421  includes a larger part  4211  and a narrower part  4212  connecting to the larger part  4211 . 
     Two through holes  422  are defined in each side panel  42  corresponding to the mounting holes  21  of the disk drive  20 . A rotating hole  423  is defined in each side panel  42 . Each side panel  42  includes a pivoting portion  424  extending from an inner surface of the side panel  42  and a positioning portion  425  protruding from the inner surface of the side panel  42 . 
     The handle  50  includes a handling portion  51  and two connecting arms  52  extending from opposite sides of the handling portion  51 . Each arm  52  includes a first pushing portion  521  and a second pushing portion  522  at a free end thereof. A pivoting hole  523 , corresponding to the pivoting portion  424 , is defined in each connecting arm  52 , adjacent to the first pushing portion  521  and the second pushing portion  522 . The connecting arm  52  includes an engaging portion  524 , adjacent to the handling portion  51 . Each connecting arm  52  is parallel to the side panel  42 . 
     Each securing member  60  includes a rotating portion  61  corresponding to the rotating hole  423  of the tray body  40  and a flange  63 . An engaging cutout  62  is defined in the securing member  60  corresponding to the engaging portion  524  of the handle  50 . A positioning cutout  64  is defined in the securing member  60  corresponding to the positioning portion  425  of the tray body  40 . The flange  63  is substantially perpendicular to the side panel  42  of the tray body  40 . 
     Referring to  FIGS. 1 through 5 , in assembly of the tray  30 , the pivoting portions  424  of the tray body  40  are pivotably connected to the pivoting holes  523  of the handle  50  to mount the handle  50  to the tray body  40 . The rotating portions  61  of the two securing members  60  are pivotably connected to the rotating holes  423  of the tray body  40  to mount the securing members  60  to the tray body  40 . 
     In assembly of the tray  30  and the disk drive  20 , the mounting holes  21  of the disk drive  20  are aligned with the through holes  422  of the tray body  40 . Four securing elements  23 , such as screws, are inserted into the through holes  422  and the mounting holes  21  to secure the disk drive  20  to the tray  30 . 
     In assembly of the tray  30  with the disk drive  20  and the enclosure  10 , the first protrusions  112  and the second protrusions  121  are received in the larger parts  4211  of the mounting openings  421 . The handling portion  51  of the handle  50  rotates along a first direction to move close to the bottom panel  41  of the tray body  40 . The second pushing portions  522  engages the corresponding first protrusion  112  and the corresponding second protrusion  121 , which enables the narrower parts  4212  to move close to the first protrusion  112  an the second protrusion  121 . The first protrusion  112  and the second protrusion  121  are received in the narrower parts  4212  when the handling portion  51  contacts the disk drive  20 . At this time, the first protrusion  112  and the second protrusion  121  are respectively disposed between the corresponding first pushing portion  521  and the corresponding second pushing portion  522 . The second pushing portions  522  are configured to prevent the tray body  40  from moving parallel to the bottom panel  41 . The two securing members  60  rotates along a second direction opposite to the first direction to enable the engaging cutouts  62  to engage the engaging portions  524  of the handle  50 . At this time, the positioning portions  425  of the tray body  40  are received in the positioning cutout  64  respectively. 
     In disassembly, the two securing members  60  rotate along the first direction to enable the engaging cutout  62  to disengage the engaging portion  524 . The handling portion  51  of the handle  50  rotates along the second direction to enable the first pushing portions  521  to engage the corresponding first protrusion  112  and the second protrusion  121 . The larger parts  4211  are driven to move close to the first protrusion  112  and the second protrusion  121 . The tray  30  is pulled up from the enclosure  10  when the first protrusion  112  and the second protrusion  121  are disposed in the larger parts  4211 . 
     It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, 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.
