## Background
BACKGROUND
1. Technical Field

DETAILED DESCRIPTION
The disclosure, including the accompanying drawings, 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, an embodiment of a chassis 10 of an electronic device includes a base 20, and a side plate 30.
A plurality of electronic components 27, such as a motherboard, is installed in the base 20. The base 20 includes a rectangular bottom wall 21, two sidewalls 23 perpendicularly extending from opposite sides of the bottom wall 21, and a first end wall 24 and a second end wall 25 perpendicularly extending from opposite ends of the bottom wall 21. A fixing portion 231 is formed on an upper section of each sidewall 23. Two fixing portions 241 and 251 are respectively formed on upper sections of the first and second end walls 24 and 25. In this embodiment, the fixing portion 231 is a plurality of threaded holes, the fixing portion 241 is a threaded hole, and the fixing portion 251 is a threaded hole defined in a stop plate 253 perpendicularly extending from a top of the second end wall 25.
The side plate 30 includes a rectangular first plate 31, and a rectangular second plate 33. Three securing portions are respectively formed on three connected edges 311, 312, and 313 of the first plate 31, corresponding to the fixing portions 241, 231, and 251 of the base 20, respectively. In this embodiment, the securing portion of the edge 311 is a through hole 3141 defined in a tab 314 perpendicularly extending down from the edge 311. The securing portion of the edge 312 is a plurality of through holes (not shown) defined in a flange 315 perpendicularly extending down from the edge 312. The securing portion of the edge 313 is a through hole 316 defined in the first plate 31 adjacent to the edge 313. A thin connection piece 318 extends from an edge 317 of the first plate 31 opposite to the edge 312. A plurality of slide slots 3182 perpendicular to the edge 317 is defined in the connection piece 318. A first fixing hole 3184 is defined in a middle of the connection piece 318. A plurality of through holes 331 and a second fixing hole 333 are defined in the second plate 33 adjacent to a first edge of the second plate 33. A securing portion 335 is formed on a second edge of the second plate 33 opposite to the first edge, corresponding to the fixing portion 231 of the base 20. In this embodiment, the securing portion 335 is a plurality of through holes defined in a flange 334 perpendicularly extending down from the second edge of the second plate 33.
Referring to FIGS. 2 to 4, in assembly, a plurality of connection members 40 is extended through the through holes 331 of the second plate 33 and the corresponding slide slots 3182 of the first plate 31. Thereby, the second plate 33 is slidably connected to the first plate 31, and the side plate 30 is assembled. The second plate 33 is moved away from the first plate 31, and the side plate 30 partially covers the base 20. The side plate 30 is moved toward the second end wall 25 until the side plate 30 entirely covers the base 20. The first and second plates 31 and 33 are moved toward each other, to allow the flanges 315 and 334 of the first and second plates 31 and 33 to engage with the corresponding sidewalls 23 of the base 20. The connection piece 318 of the first plate 31 is covered by the second plate 33, and the connection members 40 engage with ends of the corresponding slide slots 3182 adjacent to the edge 317 of the first plate 31. The second fixing hole 333 of the second plate 33 aligns with the first fixing hole 3184 of the first plate 31. A fastener 50, such as a screw, is extended through the second fixing hole 333 and engages in the first fixing hole 3184, to fix the second plate 33 to the first plate 31. A plurality of screws (not shown) is extended through the securing portions of the first and second plates 31 and 33, and engages in the corresponding fixing portions 231, 241, and 251 of the base 20, to fix the side plate 30 to the base 20. Thereby, the chassis 10 is assembled.
To open the chassis 10, the screws mounted to the side plate 30 and the base 20 are detached. Thereby, the side plate 30 is disengaged from the base 20. The fastener 50 is detached, to disengage the second plate 33 from the first plate 31. The first and second plates 31 and 33 are slid away from each other, to allow the flanges 315 and 334 of the first and second plates 31 and 33 to separate from the corresponding sidewalls 23 of the base 20. The side plate 30 can be easily detached from the base 20 through sliding away from the second end wall 25, because there is no friction between the flanges 315, 334 and the corresponding sidewalls 23.
In other embodiments, the fixing portions of the base 20 and the securing portions of the side plate 30 may be latches or hooks.
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 details, especially in matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
