BACKGROUND
1. Technical Field
The present invention relates to storage device modules and, more particularly, to a data storage device module with a screw mounting structure.
2. Description of Related Art
An electronic apparatus, such as a desktop computer, tower computer, server, or the like, usually includes storage devices, such as hard disk drives, compact disk read-only memory (CD-ROM) drives, digital video disc (DVD) drives, floppy disk drives, and the like. These storage devices are typically added to increase the functionality of the electronic apparatus as desired by a user.
The installation of a hard disk drive in a computer typically involves the use of screws to attach the hard disk drive to a bracket to form a storage device module, which is extractably mounted in a computer chassis. However, the screws of the storage device module are easily lost.

DETAILED DESCRIPTION
Referring to FIG. 1, an exemplary embodiment of a storage device module includes a storage device 10, a bracket 20 for receiving the storage device 10, two mounting members 30 attached to opposite sides of the bracket 20 respectively, and a plurality of screws 40. A plurality of mounting holes 12 is defined in opposite sides of the storage device 10.
The bracket 20 includes a bottom wall 21, two sidewalls 22 perpendicularly extending up from opposite sides of the bottom wall 21, and an end wall 24 perpendicularly extending up from one end of the bottom wall 21 and connecting to the sidewalls 22. The sidewalls 22 are parallel to each other. A plurality of long slots is defined in the bottom wall 21 for heat dissipating. Each sidewall 22 defines a plurality of through holes 221 corresponding to the mounting holes 12 of the storage device 10. Two L-shaped first locating tabs 222 extend from an upper portion of an outer surface of each sidewall 222 towards a lower portion of the outer surface of the sidewall 222. An L-shaped second locating tab 224 extends from the lower portion of the outer surface of each sidewall 22 toward the upper portion. A locating block 226 is formed on the outer surface of each sidewall 22, away from the end wall 24. A plurality of tongue-shaped resilient pieces 242 extend from the end wall 24, for shock absorption of the storage device 10.
Referring to FIG. 2, each mounting member 30 is a generally long plate. A plurality of cutouts 31 are defined in opposite sides of the mounting member 30, corresponding to the first and second locating tabs 222 and 224. A protrusion 312 extends into each cutout 31 from an edge bounding the cutout 31. A plurality of screw mounting structures 32 is arranged on an outer surface of each mounting member 30, opposite to the bracket 20. Each screw mounting structure 32 defines a through hole 321, corresponding to one of the through holes 221 of the bracket 20. The screw mounting structure 32 includes two hooks 322 perpendicularly extend from the outer surface of the mounting member 30 and opposite to each other across the through hole 321, and two retainers 326 perpendicularly extend from the outer surface of the mounting member 30 and opposite to each other around the through hole 321. The hooks 322 and the retainers 326 are alternately arranged around the through hole 321. A wedge-shaped protuberance 323 extends from a top portion of each hook 322. The protuberance 323 includes a slanting guiding surface 324 opposite to the mounting member 30 and a stop surface 325 facing the mounting member 30. Each retainer 326 is generally J-shaped and includes a main body (not labeled) extending from the mounting member 30, a resilient portion 327 bent towards the other retainer 326 from a distal end of the main body, and a wedge 328 protruding from a distal end of the resilient portion 327 and facing the other retainer 326. The wedge 328 includes a first inclined surface 3281 opposite to the mounting member 30 and a second inclined surface 3282 facing the mounting member 30. A distance between the protuberance 323 and the outer surface of the mounting member 30 is greater than a distance between the wedge 328 and the outer surface of the mounting member 30, for receiving a head of one of the screws 40 between the wedge 328 and the protuberance 323. A plurality of ribs 38 extend from the outer surface of the mounting member 30. The plurality of ribs 38 are taller than the hooks 322 and the retainers 326 of the screw mounting structure 32, for protecting the screw mounting structure 32 from being damaged. An operating portion 34 is formed from one end of the mounting member 30. A wedge-shaped block 36 (shown in FIG. 1) extends from an end of an inner surface of the mounting member 30, facing the bracket 20.
Referring to FIG. 3, in assembly, each mounting member 30 is in tight contact one of the sidewalls 22 of the bracket 20, with the cutouts 31 of the mounting member 30 aligning with the first and second locating tabs 222 and 224. The mounting member 30 is slid towards the end wall 24 of the bracket 20, until the protrusions 312 of the mounting member 30 are located under and engage with the corresponding locating pieces 222 and 224. The mounting members 30 are attached to the sidewalls 22 of the bracket 20. The wedge-shaped blocks 36 of the mounting members 30 engage with the locating blocks 226 of the bracket 20.
Referring to FIGS. 4 to 7, the head of each screw 40 resists against the guiding surfaces 324 of the hooks 322 to deform the hooks 322, allowing the head of the screw 40 riding over the protuberances 323. The head of the screw 40 is located between the stop surfaces 325 of the hooks 322 and the wedges 328 of the retainers 326. The screw portion of the screw 40 extends through the through hole 321 of the mounting member 30. Therefore, the screw 40 cannot disengage from the screw mounting structure 32 freely.
To mount the storage device 100 the bracket 20, the storage device 10 is received in the bracket 20 with the mounting holes 12 of the storage device 10 aligning with the through holes 221 of the bracket 20. The head of each screw 40 is rotated to press the first inclined surface 3281 to deform the resilient portion 327, for the head of the screw 40 riding over the wedge 328, therefore, the screw portion of the screw 40 passes through the through hole 321 of the mounting member 30 and the through hole 221 of the bracket 20 to screw into the corresponding mounting hole 12 of the storage device 10. As a result, the storage device 10 is mounted to the bracket 20. The head of the screw 40 is received between the wedge 328 of the retainer 326 and the outer surface of the mounting member 30.
To detach the storage device module 10 from the bracket 20, the head of each screw 40 is rotated reversely. The head of the screw 40 presses the second inclined surfaces 3282 to deform the resilient portions 327, for the head of the screw 40 riding over the wedge 328 to be received between the stop surfaces 325 of the hooks 322 and the wedges 328 of the retainers 326. The screw portion of the screw 40 disengages from the corresponding mounting hole 12 of the storage device 10. Therefore the storage device 10 can be drawn out from the bracket 20.
