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”.
FIGS. 1 and 2 illustrate an electronic device enclosure in accordance with an embodiment. The electronic device enclosure includes a bracket 10, a positioning member 20 secured to the bracket 10, and a receiving case 30 for receiving the bracket 10. The bracket 10 is used to secure a first storage device 70 and a second storage device 80. The second storage device 80 is smaller than the first storage device 70.
The bracket 10 includes a bottom panel 11, a first side panel 131 extending from a first edge of the bottom panel 11, a second side panel 15 extending from a second opposite edge of the bottom panel 11, a third side panel 135, and a connecting panel 133 connected to the first side panel 131 and the third side panel 135. In one embodiment, the first side panel 131 is substantially parallel to the second side panel 15 and the third side panel 135, and the connecting panel 133 is substantially parallel to the bottom panel 11 and perpendicular to the first side panel 131. The first storage device 70 is located between the second side panel 15 and the third side panel 135, and the second storage device 80 is located between the second side panel 15 and the first side panel 131.
Two first clipping slots 1311 are defined in the first side panel 131. Two through holes 1331, adjacent to the third side panel 135, are defined in the connecting panel 133. Two second clipping slots 1351 and a first mounting hole 1352 are defined in the third side panel 135. A clamping tongue 1353 extends outwardly from the third side panel 135.
Two third clipping slots 151 and two fourth clipping slots 153 are defined in the second side panel 15. The two third clipping slots 151 and the two fourth clipping slots 153 correspond to the two first clipping slots 1311 and the two second clipping slots 1351. In one embodiment, the two first clipping slots 1311, the two second clipping slots 1351, the two third clipping slots 151, and the two fourth clipping slots 153 have a same L-shaped configuration. A second mounting hole 154 is defined in the second side panel 15. A hook 157, adjacent to the second mounting hole 154, extends from an upper edge of the second side panel 15. Two flanges 155, 1353 extend from the second side panel 15 and the third side panel 135.
FIG. 3 illustrates the positioning member 20 of one embodiment. The positioning member 20 includes a securing portion 21, a clamping portion 23, and a positioning portion 25. Two fixing holes 211 are defined in the securing portion 21 and correspond to the two through holes 1331. The clamping portion 23 extends substantially perpendicularly from an upper surface of the securing portion 21. A shielding portion 231 extends from the clamping portion 23 and is above the positioning portion 25, for preventing cables touching or interfering with the positioning portion 25. In one embodiment, a cross-section of the shielding portion 231 is arcuate. A clamping slot 232, with a guiding surface 2321, is defined in the center of the clamping portion 23. In one embodiment, the guiding surface 2321 is slanted, and the clamping slot 232 is U-shaped. An inserting portion 251 extends from the distal end of the positioning portion 25, and two protruding portions 253 protrude from the positioning portion 25 and are located on a side of the inserting portion 251. In one embodiment, the positioning portion 25 is hollow column and deformable, and the inserting portion 251 is semi-circular.
FIGS. 1-2, illustrate the receiving case 30 of one embodiment. The receiving case 30 includes a bottom plate 31, a front plate 33, a side plate 35, and a tray 37 attached to the bottom plate 31. A retaining piece 351, with a retaining hole 3511, is attached to the front of the side plate 35. The tray 37 includes a mounting plate 371 and a supporting plate 373 connected to the front plate 33. The supporting plate 373 is substantially perpendicular to the mounting plate 371 and substantially parallel to the front plate 33. In one embodiment, the mounting plate 371 is substantially parallel to the front plate 33. Two supporting flanges 3715, 353 extend from the mounting plate 371 and the side plate 35. A sliding rail 3711, with a sliding slot 3712, is defined in the mounting plate 371, and a guiding slot 3717 is defined in the supporting flange 3715. The guiding slot 3717 communicates with the sliding slot 3712. In one embodiment, the sliding rail 3711 and the sliding slot 3712 are arcuate. A third mounting hole 3713 is defined in the mounting plate 371 corresponding to the first mounting hole 1352. A blocking tab 3731 and a supporting stage 3733 are located on the supporting plate 373.
FIGS. 4-5 illustrate the assembly of the electronic device enclosure in accordance with an embodiment. In assembly, the securing portion 21 abuts the connecting panel 133, and the clamping tongue 1353 is clamped into the clamping slot 232 via the guiding surface 2321, to secure the clamping portion 23 to the third side panel 135. The fixing holes 211 are aligned with the through holes 1331, and two fixing members (not shown), such as screws, are engaged into the fixing holes 211 and the through holes 1331. Thus, the securing portion 21 is secured to the connecting panel 133.
The first mounting hole 1352 is aligned with the third mounting hole 3713, and the second mounting hole 154 is aligned with the fourth mounting hole 3511. A plurality of mounting members, such as screws, are engaged in the first mounting hole 1352 and the third mounting hole 3713, and engaged in the second mounting hole 154 and the fourth mounting hole 3511, to rotatably secure the bracket 10 to the receiving case 30. The bracket 10 is rotated relative to the receiving case 30, until the inserting portion 251 is received in the guiding slot 3717, and the hook 157 abuts the retaining piece 351.
The bracket 10 is further rotated, and the positioning portion 25 is slid into the sliding slot 3712 to engage the two protruding portions 253 with the opposite edges of the sliding rail 3711. The positioning portion 25 is deformed by the sliding rail 3711, until the hook 157 clips onto the retaining piece 351. At this point, the flanges 155, 153 abut the supporting flanges 3715, 353. The connecting panel 133 abuts the supporting plate 373 to clip the blocking tab 3731 in a hole (not shown) of the connecting panel 133, and the bottom panel 11 abuts the supporting stage 3733. The first storage device 70 is located between the second side panel 15 and the third side panel 135, and two first mounting members (not labeled) of the first storage device 70 are received in the second and fourth clipping slots 1351 and 153. The second storage device 80 is located between the second side panel 15 and the first side panel 131, and two second mounting members (not labeled) of the second storage device 80 are received in the first and third clipping slots 1311 and 151. Thus, the storage devices 70 and 80 are secured to the bracket 10.
In one embodiment, the positioning portion 25 is made of polycarbonate and glass fibre, and the receiving case 30 is made of metal. Thus, the positioning portion 25 can be an interference fit with the sliding rail 3711 via the two protruding portion 253. Friction is generated between the two protruding portions 253 and the sliding rail 3711. When the bracket 10 is rotated relative to the receiving case 30, the positioning portion 25 is slid in the sliding slot 3712 and the positioning portion 25 can be positioned and held in position anywhere along the sliding rail 3711, via the friction generated between the two protruding portions 253 and the sliding rail 3711.
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 the 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.
