## Title
Enclosure with removable panel

## Abstract

An enclosure includes a main body, a front panel, a pivot member pivotably attaching the front panel to the main body, and a positioning member. The pivot member is substantially U-shaped, allowing the front panel a large angle of rotational movement relative to the main body. Positioning members are in place to facilitate the refitting of the front panel.

## Background
BACKGROUND
1. Technical Field

DETAILED DESCRIPTION
The disclosure, including the accompanying drawing, is illustrated by way of example and not by way of limitation. 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 FIG. 1 to FIG. 3, an exemplary embodiment of an enclosure of an electronic device, such as a server, includes a main body 10, a front panel 20, three pivot members 30, three mounting members 40, three shafts 50 (shown in FIG. 5), three resilient members 60 (shown in FIG. 5), and three positioning members 70.
The main body 10 is substantially box-shaped to enclose a motherboard, a plurality of hard disk drives, a plurality of fans, and other functioning elements (all not shown in the drawings). The main body 10 includes a front plate 12, an opening 11 defined in a center of the front plate 12. The front plate 12 includes a first side plate 121 and a second side plate 122 bounding the opening 11.
The first side plate 121 defines three substantially L-shaped through holes 123 from top to bottom and away from the opening 11. Two mounting holes 124 are also defined in the first side plate 121, respectively above and below each through hole 123.
Two locking portions 125 are formed on the second side plate 122, towards the top and bottom of it respectively, and opposite to the first side plate 121.
Referring to FIG. 5, the front panel 20 includes a pivot side 22, and a locking side 24 opposite to the pivot side 22. Two parallel pivot portions 222 are formed on the pivot side 22, corresponding to each through hole 123. A pivot hole (not labeled) is defined in each pivot portion 222. A rod 226 protrudes from the pivot side 22, adjacent to each pivot portion 222. Two spaced hooks 242 are formed from the locking side 24.
Referring to FIG. 1 and FIG. 5, each pivot member 30 includes a substantially U-shaped base 31. The base 31 includes a first portion 311 and a second portion 312 spaced from and opposite to the first portion 311. An inserting portion 32 substantially perpendicular extends from the distal end of the first portion 311. A pin 33 extends down from the bottom of the inserting portion 32. Two parallel connecting portions 34 extend in a substantially perpendicular manner from the distal end of the second portion 312. Each connecting portion 34 defines a connecting hole (not labeled). A tab 344 extends at right angles from the side of each connecting portion 34, such that the two tabs 344 are coplanar and at the greatest possible distance from each other.
Referring to FIG. 1, FIG. 4, and FIG. 5, each mounting member 40 is a substantially L-shaped box and defines an L-shaped receiving space 41. Two mounting pieces 42 are formed from the mounting member 40 beside the receiving space 41. A mounting hole 422 is defined in each mounting piece 42. The mounting member 40 includes an L-shaped top wall 43, a bottom wall 44, and a sidewall 45 defining a mounting hole 46 and connecting the top wall 43 and the bottom wall 44. The mounting pieces 42 extend from the top wall 43 and the bottom wall 44, respectively. The mounting member 40 defines a pivot hole 442 in the bottom wall 44, communicating with the receiving space 41. A mounting piece 431 extends up from the top wall 43.
In this embodiment, each resilient member 60 is a torsion spring and includes an engaging portion 61 extending out from the middle of the spring, and two fingers 62 at opposite ends of the resilient member 60.
Referring to FIG. 3, each positioning member 70 is a substantially L-shaped piece, and includes a fixing piece 71 defining a mounting hole 73, and a resilient piece 72 substantially perpendicular extending from one end of the fixing piece 71. A longitudinal through slot 722 is defined in the middle of the resilient piece 72. A positioning piece 74 extends down in a substantially perpendicular manner from the distal end of a side of the resilient piece 72, opposite to and perpendicular to the fixing piece 71. The positioning piece 74 is substantially triangular and includes a first slope 742 opposite to the fixing piece 71, and a second slope 744 opposite to the first slope 742 and facing the fixing piece 71.
Referring to FIG. 5 to FIG. 8, in assembly, the front panel 20 is pivotably mounted to the main body 10 using the pivot members 30. The assembly process of only one of the pivot members 30 is described as an example. The fixing piece 71 is fixed to an outer surface of the sidewall 45 of the mounting member 40 by a screw (not shown) extending through the mounting hole 73 of the fixing piece 71 to engage in the mounting hole 46 of the sidewall 45. The resilient piece 72 resists against the outer surface of a low portion of the top wall 43. The mounting piece 431 extends through the through slot 722. The mounting member 40 is fixed to the inner surface of the front plate 12, by two screws (not shown) which extend through the mounting holes 422 of the mounting pieces 42 to engage in the first side plate 121. The receiving space 41 aligns with the through hole 123. The connecting portions 34 of the pivot member 30 are arranged between the pivot portions 222. The connecting holes of the connecting portions 34 align with the corresponding pivot holes of the pivot portions 222. The shaft 50 extends through one of the pivot holes, the connecting holes, and the other pivot hole. The resilient members 60 are arranged between the connecting portions 34 and set around the shaft 50. The engaging portion 61 resists against the base 31. The fingers 62 resist against the front panel 20 and are held in place by the rods 226. The inserting portion 32 extends through the receiving space 41 and the pin 33 is pivotably inserted in the pivot hole 442.
To close the front panel 20 relative to the main body 10, thereby covering the opening 11, the front panel 20 is pivoted. The locking side 24 of the front panel 20 moves towards the front plate 12 of the main body 10, and the pin 33 is rotated in the pivot hole 442. The first portion 311 of the pivot member 30 resists against the first slope 742 of the positioning member 70 and deforms the resilient piece 72, thereby raising the positioning piece 74. After the base 31 passes over the positioning piece 74, the resilient piece 72 restores itself by moving down the positioning piece 74 between the first portion 311 and the second portion 312. The positioning piece 74 resists against an inner surface of the first portion 311 to position the base 31. The hooks 242 latch the locking portions 125.
To release the front panel 20 relative to the main body 10, the front panel 20 is pivoted. The hooks 242 are disengaged from the locking portions 125. The locking side 24 of the front panel 20 moves away from the front plate 12 of the main body 10, and the pin 33 rotates in the pivot hole 442. The first portion 311 resists against the second slope 744 to deform the resilient piece 72, thereby raising the positioning piece 74. After the base 31 passes over the positioning piece 74, the front panel 20 rises up to release the inserting portion 32 from the pivot hole 442, allowing the removal of the front panel 20 from the main body 10.
In this embodiment, the pivot members 30 are substantially U-shaped to allow a large angle of rotation by the front panel 20 relative to the main body 10. The positioning members 70 limit the front panel 20 and perform a necessary function in the assembly or disassembly of the front panel 20.
It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, 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 present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
