## Background
BACKGROUND
1. Technical Field
The present disclosure relates to a computer enclosure with a cover mountable thereon and removable therefrom.
2. Description of Related Art
A frequently used computer enclosure includes a chassis and a cover mounted to the chassis. The chassis includes a pair of parallel side panels, each defining a plurality of slots defined therein. The cover forms a plurality of hooks on opposite edges corresponding to the slots of the side panels. In assembly, the hooks of the cover are received in the slots of the side panels, and some fasteners, such as screws, engage mounting holes defined in the chassis and the cover. Thus, the cover is mounted to the chassis. However, it is complicated to mount or remove the cover.
What is needed, therefore, is a computer enclosure with a cover conveniently mounted thereon and removed therefrom.

DETAILED DESCRIPTION
Referring to FIG. 1, FIG. 2 and FIG. 6, an embodiment of a computer enclosure includes a chassis 10 and a cover 40 detachably mounted thereon.
The chassis 10 includes side panels 11, 12, 13, 14. A first flange 112 extends from a top edge of the side panel 11, and a second flange 122 is extends from a top edge of the side panel 12. A plurality of assembly slots 114 is defined in the first flange 112.
The cover 40 includes a receiving portion 42 with two fixing holes 422. An opening 424 is defined in the receiving portion 42, and a locating hole 425 is defined in the receiving portion 42 adjacent to the opening 424. A through opening 426 is defined in one edge of the receiving portion 42. A locating piece 4242 protrudes from one edge of the opening 424. An elongate sliding channel 44 is defined on one edge of the cover 40 adjacent to the receiving portion 42, and a bent piece 49 is formed in another edge of the cover 40 corresponding to the second flange 122 of the chassis 10. Referring to FIG. 4, a first retaining portion 444 is disposed on one side of the sliding channel 44.
A rotary member 43 is received in the receiving portion 42 with two tabs 432 disposed on opposite sides thereof. A pivot hole 4322 is defined in each tab 432. A positioning block 434 protrudes from the rotary member 43 corresponding to the through opening 426 of the receiving portion 42.
Referring to FIG. 3, a sliding member 46 is slidably received in the sliding channel 44. A plurality of hooks 462 protrudes from the sliding member 46 corresponding to the assembly slots 114 of the side panel 11. Each hook 462 includes an inclined edge 4622. An inclined piece 464 is disposed on the sliding member 46 adjacent to the through opening 426 of the receiving portion 42, engaging the positioning block 434 of the rotary member 43. A second retaining portion 468 is formed on one side of the sliding member 46.
A first resilient component 70 is installed on the cover 40. One end of the first resilient component 70 is connected to the first retaining portion 444 of the sliding channel 44, and the other end of the first resilient component 70 is connected to the second retaining portion 468 of the sliding member 46.
Referring to FIG. 4 and FIG. 5, the rotary member 43 is placed in the receiving portion 42, and a pivot shaft 50 is received in the fixing holes 422 of the receiving portion 42 and the pivot holes 4322 of the rotary member 43. A second resilient component 60 is mounted on the cover 40 and placed around the locating piece 4242 of the receiving portion 42. The second resilient component 60 includes two protrusions 62, 64, with protrusion 62 received in the locating hole 425 of the receiving portion 42, and the protrusion 64 positioned between the receiving portion 42 and the rotary member 43. Thereby, the rotary member 43 is pivotally installed in the receiving portion 42. The positioning block 434 of the rotary member 43 passes through the through hole 426 of the receiving portion 42, and abuts the inclined piece 464 of the sliding member 46.
Referring from FIGS. 4 and 6, during assembly, the bent piece 49 of the cover 40 is secured to the second flange 122 of the side panel 12 of the chassis 10. The cover 40 rotates toward the chassis 10 at a connection between the bent piece 49 and the second flange 122 until the inclined edges 4622 of the hooks 462 of the sliding member 46 correspondingly abut the assembly slots 114 of the first flange 112. The cover 40 is pressed to drive the inclined edges 4622 of the hooks 462 against the assembly slots 114, and the sliding member 46 slides in the sliding channel 44 along a first direction away from the first retaining portion 444. The first resilient component 70 is deformed elastically and elongated. When the inclined edges 4622 of the hooks 462 run through the corresponding assembly slots 114, the first resilient component 70 returns to an original state. The sliding member 46 slides in the sliding channel 44 along a second direction opposite to the first direction until the hooks 462 are engaged in the corresponding assembly slots 114. The cover 40 is thus mounted to the chassis 10, and the inclined piece 464 of the sliding member 46 abuts the positioning block 434 of the rotary member 43.
For removal, the rotary member 43 is rotated, the positioning block 434 rotates along the rotary member 43 and abuts the inclined piece 464 of the sliding member 46, which slides along the first direction until the hooks 462 thereof disengage from the assembly slots 114 of the chassis 10. The first resilient component 70 is deformed elastically and elongated. The single movement of the rotary member 43 presses against the protrusion 64 of the second resilient component 60 and pulls the cover 40 away from chassis 10. When the hooks 462 disengage from the corresponding assembly slots 114, the cover 40 is removed from the chassis 10.
When the cover 40 is removed from the chassis 10, the rotary member 43 is released. The second resilient component 60 returns to an original state to rotate the rotary member 43 into the receiving portion 42. The first resilient component 70 returns to the original state to slide the sliding member 46 along the second direction until the inclined piece 464 is blocked by the positioning block 434 of the rotary member 43.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of preferred embodiments, together with details of the structures and functions of the preferred 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 invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
