DETAILED DESCRIPTION
The present disclosure, including the accompanying drawings, is illustrated by way of examples 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.”
FIG. 1 shows an embodiment of an electronic device including a rack 300 and a movable module 100. The rack 300 includes a bottom wall 301, a top wall 302 opposite to the bottom wall 301, two opposite end walls 303 connected substantially perpendicularly between the bottom wall 301 and the top wall 302, and a plurality of spaced partition plates 305 connected substantially perpendicularly between the bottom wall 301 and the top wall 302. The rack 300 is divided into a plurality of receiving spaces 306 by the partition plates 305. The bottom wall 301 and the top wall 302 each define a pair of latching holes 308 corresponding to each receiving space 306.
FIG. 2 and FIG. 3 show the movable module 100 including a server unit 20 and a positioning apparatus 40. A plurality of components (not shown), such as a motherboard and a data storage apparatus, is installed in the server unit 20. The server unit 20 includes a substantially rectangular side plate 22 and a U-shaped operation portion 26 protruding from a front end of the side plate 22. The side plate 22 defines a plurality of screw holes 24 in four of its corners.
The positioning apparatus 40 includes a frame 42, two pivot members 44, an operation member 46, and a resilient member 48.
The frame 42 includes a substantially rectangular connecting plate 422, two opposite flanges 423 protruding substantially perpendicularly out from two opposite sides of the connecting plate 422, and a U-shaped hook 425 protruding forward from a front end of the connecting plate 422. The connecting plate 422 and the flanges 423 cooperatively bound a receiving space 424. The front end of the connecting plate 422 defines a long opening 4221 approximately along a centerline of the connecting plate 422 and two substantially parallel slide slots 4223 in two opposite sides of the connecting plate 422. The opening 4221 is located adjacent to the hook 425, and the slide slots 4223 are located adjacent to the flanges 423. A junction of the connecting plate 422 and each flange 423 defines two spaced through slots 4231 and two spaced guiding slots 4232. Two shafts 4225 protrude substantially perpendicularly in from a rear end of the connecting plate 422 adjacent to the two flanges 423. A first hook 4226 protrudes in from the rear end of the connecting plate 422 between the shafts 4225. A mounting block 4228 protrudes substantially perpendicularly out from the rear end of the connecting plate 422 opposite to the shafts 4425. The connecting plate 422 defines four through holes 4229 in four of its corners.
Each pivot member 44 includes a rectangular pivot plate 442 and an extending plate 443 extending forward from a front end of the pivot plate 442. A rear end of the pivot plate 442 defines a shaft hole 445. A junction of the pivot plate 442 and the extending plate 443 slantingly defines a guiding slot 446. Two spaced latching pieces 448 protrude out from sides of the pivot plate 442 and the extending plate 443.
The operation member 46 includes a rectangular sliding plate 462 and four guiding hooks 464 extending substantially perpendicularly from four of its corners along a same direction. A front end of the sliding plate 462 defines an operation hole 465. A guiding rim 466 extends substantially perpendicularly from the sliding plate 462 around the operation hole 465 and extends substantially along the same direction as the guiding hooks 464. A second hook 467 protrudes out from a rear end of the sliding plate 462. Two spaced sliding poles 468 protrude substantially perpendicularly from the rear end of the sliding plate 462, opposite to the second hook 467.
In one embodiment, the resilient member 48 is a coil spring and includes a first positioning end 482 and a second positioning end 484 opposite to the first positioning end 482.
In assembly of the positioning apparatus 40, the pivot members 44 are placed in the receiving space 424 of the frame 42. The pivot members 44 are located at two opposite sides of the receiving space 424, with the latching pieces 448 of each pivot member 44 aligning with the adjacent through slots 4231. The shafts 4225 are rotatably inserted into the shaft holes 445 of the pivot members 44. The sliding poles 468 extend through the guiding slots 446 of the pivot members 44 and are slidably received in the slide slots 4223 of the frame 42. The guiding rim 466 slidably inserts into the opening 4221 of the frame 42, and the guiding hooks 464 hook into the guiding slots 4232 of the frame 42 onto an outer surface of the connecting plate 422. Thus, the operation member 46 is slidably installed onto the frame 42. The first positioning end 482 of the resilient member 48 is hooked to the first hook 4226 of the frame 42, and the second positioning end 484 of the resilient member 48 is hooked to the second hook 467 of the operation member 46. The resilient member 48 biases the operation member 46 to move adjacent to the shafts 4225. The guiding hooks 464 are slid in the guiding slots 4232, the guiding rim 466 is slid in the guiding opening 4221, and the sliding poles 468 are slid in the guiding slots 446 and the corresponding slide slots 4223. Thus, the sliding poles 468 slidably abut against inner walls bounding the guiding slots 446, causing the pivot members 44 to rotate away from each other, such that the latching pieces 448 extend through the corresponding through slots 4231.
In assembly of the positioning apparatus 40 to the server unit 20, the outer surface of the frame 42 engages with the side plate 22 with the hook 425 adjacent to the operation portion 26. The mounting block 4228 is latched to a rear end of the side plate 22. A plurality of screws (not shown) extends through the through holes 4229 into the corresponding screw holes 24.
FIGS. 4-6 show that to install the movable module 100 to the rack 300, the operation member 46 is slid adjacent to the hook 425 by pulling the operation member 46 by the operation hole 465 to deform the resilient member 48. The sliding poles 468 slidably abut against the inner walls bounding the guiding slots 446, causing the pivot members 44 to rotate toward each other. Each pivot member 44 is rotated about the corresponding shaft 4225, such that the latching pieces 448 are received in the receiving space 424 of the frame 42. The rear end of the movable module 100 is inserted into the receiving space 306 of the rack 300. The sliding plate 462 is released, and the resilient member 48 is partially restored to bias the operation member 46 to move away from the hook 425. The sliding poles 468 slidably abut against the inner walls bounding the guiding slots 446, causing the pivot members 44 to rotate away from each other, such that the latching pieces 448 abut against the inner surfaces of the top wall 302 and the bottom wall 301, respectively. The operation portion 46 is slid further to move the movable module 100 into the receiving space 306 further until the through slots 4231 align with the latching holes 308 of the rack 300. The resilient member 48 is further restored to bias the latching pieces 448 to extend through the through slots 4231 and the corresponding latching holes 308, thus installing the movable module 100 into the rack 300.
To detach the movable module 100 from the rack 300, the operation member 46 is slid adjacent to the hook 425 by pulling the operation member 46 by the operation hole 465, deforming the resilient member 48. This causes the pivot members 44 to rotate toward each other, such that the latching pieces 448 detach from the latching holes 308. Thus, the movable module 100 is easily separated from the rack 300.
It is to be understood, however, that even though numerous characteristics and advantages of the embodiment have been set forth in the foregoing description, together with details of the structure and function of the embodiment, 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 present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
