Patent Document

BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates to an electronic device enclosure, and particularly to an electronic device enclosure with a handle. 
         [0003]    2. Description of Related Art 
         [0004]    Electronic equipment, such as servers, may contain heavy electronic modules, such as power supplies and fan modules. The heavy electronic modules are secured in an enclosure of the electronic equipment. A handle may be rotatably mounted to the enclosure by a rotating shaft for conveniently moving the enclosure. However, when moving the enclosure, the handle often needs to be pulled out forcefully. Therefore, there is room for improvement in the art.

     DETAILED DESCRIPTION 
       [0011]    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.” 
         [0012]      FIG. 1  and  FIG. 2  show one embodiment of an electronic device enclosure for securing an electronic module (not shown). The electronic device enclosure includes a chassis  10 , a cover  20 , a handle  30 , and a securing assembly  100 . 
         [0013]    The chassis  10  includes a bottom plate  11 , a front plate  12 , and two side plates  13 . The two side plates  13  are opposite to each other. In this embodiment, the bottom plate  11  is substantially perpendicular to the front plate  12  and the side plates  13 , and the front plate  12  is substantially perpendicular to the side plates  13 . Two flanges  15  extend from opposite side edges of the front plate  12 , respectively. The flanges  15  are substantially perpendicular to the bottom plate  11 . Each flange  15  is riveted to a corresponding side plate  13 . A holding plate  16  extends from a top edge of the front plate  12 , which is substantially parallel to bottom plate  11 . In this embodiment, the flanges  15  are substantially parallel to each side plate  13 , and the holding plate  16  is substantially perpendicular to bottom plate  11 . A pivoting shaft  151  is located on the flange  15 . 
         [0014]    The cover  20  includes a top wall  21  and two sidewalls  23 . The top wall  21  defines a through hole  211 . A pair of pivoting pieces  213  extends from a bottom surface of the top wall  21 . Each pivoting piece  213  defines a pivoting hole  2131 . In this embodiment, the top wall  21  is substantially perpendicular to each sidewall  23 , and each pivoting piece  213  is substantially perpendicular to the top wall  21  and the sidewall  23 . A resilient piece  25  extends from each sidewall  23 . The resilient piece  25  extends slantingly out of the cover  20 . 
         [0015]    The handle  30  includes a mounting plate  31  and two rotating arms  33  connected to the mounting plate  31 . A latching piece  310  is secured to the mounting plate  31 . The latching piece  310  defines a latching slot  311 . The latching slot  311  extends from a side edge of the latching piece  310 . Each rotating arm  33  defines a pivoting hole  331 . In this embodiment, the latching piece  310  is substantially perpendicular to the mounting plate  31 . 
         [0016]    The securing assembly  100  includes a latching member  50  and a resilient member  60 . 
         [0017]    The latching member  50  includes a holding piece  51 , a connecting piece  53 , and a limiting piece  55 . The holding piece  51  and the limiting piece  55  extend from opposite edges of the connecting piece  53 . The connecting piece  53  is slanted relative to the holding piece  51  and the limiting piece  55 . In one embodiment, the holding piece  51  is substantially parallel to the limiting piece  55 . A pressing portion  511  extends from a top surface of the holding piece  51 . A positioning post  513  extends from a bottom surface of the holding piece  51 . The pressing portion  511  is received in the through hole  211 . A pivoting shaft  56  is located in an intersection of the holding piece  51  and the connecting piece  53 . A limiting block  551  extends downwards from the limiting piece  55 . 
         [0018]    In this embodiment, the resilient member  60  is a coiled spring and a compression spring. 
         [0019]      FIG. 3  and  FIG. 4  show that in assembly, the resilient member  60  is placed on the holding plate  16 . The positioning post  513  is inserted in the resilient member  60 . Each end of the pivoting shaft  56  is pivotably received in the pivoting hole  2131  by elastically deforming the pivoting pieces  213 . The pressing portion  511  extends out of the top wall  21  through the through hole  211 . The cover  20  covers the chassis  10 . The sidewall  23  is secured to the flange  15  by riveting, soldering, or other securing methods. The cover  20  covers the chassis  10 . The top wall  21  is substantially parallel to the holding plate  16 . A first end of the resilient member  60  abuts a bottom surface of the holding piece  51 , and a second end of the resilient member  60  abuts the holding plate  16 . Thus, when the pressing portion  511  is pressed downwards, the latching member  50  is rotated about the pivoting shaft  56  to press the resilient member  60 . The pivoting shaft  56  is substantially parallel to the top wall  21  and the sidewall  23 . The pivoting shaft  151  is inserted through the pivoting hole  331 , to rotatably mount the rotating arm  33  to the flange  15 . In this position, the resilient member  60  and the latching member  50  are in an initial position. 
         [0020]    In assembly of the handle  30 , the handle  30  is rotated towards the holding plate  16 , until blocked by the limiting block  551 . The handle  30  is further rotated to rotate the limiting piece  55  away from the holding plate  16 . The holding piece  51  is rotated towards the holding plate  16  and elastically deform the resilient member  60 . When the limiting block  551  is aligned with the latching hole  311 , the mounting plate  31  resists and elastically deforms the resilient piece  25 , the handle  30  is released, the resilient member  60  rebounds to engage the limiting block  551  in the latching hole  311 , to secure the handle  30  to the chassis  10 . In this position, the latching member  50  is in a closed position, and the limiting piece  55  is substantially parallel to the latching piece  310 . 
         [0021]      FIG. 5  shows that to open the handle  30 , the pressing portion  511  is pressed downwards to rotate the holding piece  51  towards the holding plate  16  and elastically deform the resilient member  60 . At the same time, the limiting piece  55  is rotated away from the holding plate  16 , until the limiting block  551  is disengaged from the latching hole  311 . The resilient member  25  rebounds to extend the mounting plate  31  outwards, thereby releasing the handle  30  from the cover  20 , and the operation member  50  is in an open position. 
         [0022]    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 the 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.
