There is a space between the front side 122 of the first inner frame 12 and the power supply 13 to form a hollow space 100 for communicating with the framework 20 (not shown) and allowing electric wires to pass through. The rear side 125 of the first inner frame 12 and the rear side 116 of the outer frame provide a hole 117, 127 respectively which correspond to a connector 134 and a switch 133 of the power supply 13. The top ends of the two lateral sides 123,124 of the first inner frame 12 provide an outward bending prop-plate 128 for upholding the outer frame of the upper framework. The junctions of the prop-plates 128 with the two opposite lateral sides 123, 124 of the first inner frame 12 provide a plurality of clasp-holes 129 respectively. The front end of the clasp-hole 129 is narrow to form a crevice 1291. The rear end of the clasp-hole 129 is wider than the front end thereof.

The slot 312 extends to the bottom of the third outer frame 31. The slot 312 is movably combined with a clasp-plate 313. An ear-plate 3131 of the clasp-plate 313 is extended to an outside of the slot 312.
The top end of the two opposite lateral sides 321, 322 of the third inner frame 32 provides a prop-plate 323 and a clasp-hole 324 respectively which correspond to the outward-bending prop-plate 128 and the clasp-hole 129 of the two opposite lateral sides 123, 124 of the first inner frame 12 as shown in FIG. 3A. The prop-plate 323 is provided for supporting the outer frame of the fourth framework (not shown). The clasp-hole 324 is provided for fastening a clasp-ear of the bottom of an inner frame of the fourth framework.
The bottoms of the two opposite lateral sides 321,322 of the third inner frame 32 provide an outward extending clasp-ear 325 respectively. The clasp-ear 325 respectively corresponds to the wider area of the rear end of the clasp-hole 129 of the prop-plates 128 as shown in FIGS. 3A and 3B. The front end of the clasp-ear 325 provides a lug 3251. There is a gap between the lug 3251 and the two opposite lateral sides 321, 322 respectively. The lug 3251 and the left and right sides 321, 322 do not joint each other respectively.
When the clasp-ear 325 of the third inner frame 32 is placed on a wider part of a clasp-hole at a rear end of a second inner frame of the second framework 20, then makes the third inner frame 32 move forward, and then the lug 3251 of the clasp-ear 325 is fastened under a second prop-plate of the second framework 20 and is placed on an outside of a crevice of a clasp-hole of the second prop-plate, then pull back the ear-plate 3131 and drive the bottom of the clasp-plate 313 to extend under the slot 312 to be fastened in the second slot of the second outer frame of the second framework 20 (not shown), allowing the third outer frame 31 not to be moved backward and the clasp-ear 325 of the third inner frame 32 not to be detached from the clasp-hole of the second inner frame of the second framework 20 so as to cause the second framework 20 to be steadily fastened to the third framework 30 as shown in FIG. 2.
Please referring to FIGS. 4A and 4B, the front side 314 of third outer frame 31 has a recess face 315 that has a through hole 316 and the two opposite lateral sides of the recess face 315 are respectively provided with a guiding groove 317. The two lateral sides of a shielding plate 318 are respectively placed in the guiding groove 317 to allow the shielding plate 318 to fit with the recess face 315 and to shield the through hole 316.
Please referring to FIG. 5, the front end of the bottom 326 of the third inner frame 32 provides a through hole 327 for allowing electric wires to pass through.
According to the embodiment of the present invention, the inner spaces of the second framework 20, the third framework 30, the fourth framework 40 and the fifth framework 50 are provided for accommodating electronic products such as a motherboard, DVD drive and hard drive. A through hole at a bottom of an inner frame can be used for communicating with the lower framework. Therefore, wires can be routed to each framework to facilitate all electronic devices. Such wires can be directly routed to the power supply of the first framework or the motherboard of the second framework. Wires are hidden in the outer frame of each framework thus they do not affect the entire modular computer design. The inner side of each framework provides a corresponding internal engaging structure which is hidden in the outer frame to cause the stackable modular personal computer to show a more consistent outward appearance.
Please referring to FIGS. 2 and 6, the upper cover 60 of the embodiment according to the present invention provides an internal engaging structure is almost the same as the internal engaging structure provided at the bottoms of the intermediate frameworks and the uppermost framework, and the internal engaging structure has a sixth inner frame 62 which is combined with an inner side of the sixth outer frame 61. A bottom of a rear end of the sixth outer frame 61 provides a slot 611 and a clasp-plate 612 respectively corresponding to the slot 312 and a clasp-plate 313 of the third outer frame 31 as shown in FIG. 4A. The two opposite lateral sides 621,622 of the sixth inner frame 62 provide a clasp-ear 623 respectively which corresponds to the two opposite lateral sides 321, 322 and the clasp-hole 324 of the prop-plate 323 of the third inner frame 32. The clasp-ear 623 and the clasp-plate 612 of the upper cover 60 are fastened to the corresponding clasp-hole and the second slot of the fifth framework 50 respectively, allowing the upper cover 60 to be combined with the fifth framework 50 firmly.
The present invention is provided for a stackable modular personal computer. Each inner frame has a hole for allowing at least one electric wire to pass through to enable the electric wires of the modular personal computer and a combination structure of each layer are all hidden in the frameworks so that an identical outlook can be obtained and it facilitates to assemble and combine each framework firmly.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
