DETAILED DESCRIPTION OF THE DISCLOSURE
Refer to FIG. 1 and FIG. 2. A computer case 100 according to the first embodiment includes a first sidewall 200, a plurality of peripheral walls 300, a retractable fence 400, and a second sidewall 500. A first side 310 of each peripheral wall 300 connects to the first sidewall 200 in a surrounding manner. In general, hardware components, such as a motherboard, a video card, fans, or hard drives, are disposed to the first sidewall 200 and are surrounded by the peripheral walls 300. A first end 410 of the retractable fence 400 is disposed to a second side 320 of each peripheral wall 300, and a second sidewall 500 connects with a second end 420 of the retractable fence 400.
The retractable fence 400 is able to reciprocate along an extending direction of the peripheral walls 300, so that an inner space of the computer case 100 is selectively increased or reduced. In other words, the extension or compression of the retractable fence 400 is mainly for adjusting the width of the inner space of the computer case 100, such that the computer case 100 is not inappropriate when a cooling module or an electronic component with different width is replaced on the motherboard.
The retractable fence 400 further includes a plurality of ring frames 430 and a plurality of stands 440. Two of the ring frames 430 respectively connect with the second side 320 of each peripheral wall 300 and the second sidewall 500 in a surrounding manner. Two opposite surfaces of each ring frame 430 are respectively formed with a trench 431. The two ends of each stand 440 are disposed in the trenches 431 of the ring frames 430 in a sliding manner. When the retractable fence 400 reciprocates along the extending direction of the peripheral walls 300, the ends of stands 440 slide in the trenches 431 with the movement of the ring frames 430. One of the advantages of the retractable fence 400 is that in the coordination of the ring frame 430 and the stands 440, the position of the retractable fence 400 can be directly adjusted according to the width of the cooling module or the electronic component, so as to increase or decrease the width of the inner space of the computer case 100.
Besides, the ring frames 430 and the stands 440 of the retractable fence 400 form a plurality of hollow portions 450. These hollow portions 450 help exhaust the heat generated by the hardware components, such as a motherboard, a power supply, a video card, or hard drives, when the computer is operating, thus cooling these hardware components.
Refer to FIG. 3 and FIG. 4. Except for the first sidewall 200, a plurality of peripheral walls 300, the retractable fence 400, and the second sidewall 500, the computer case 100 according to the second embodiment further includes a positioning component 600. One end of the positioning component 600 is fixed on the second sidewall 500, and the positioning component 600 is located at an outer surface of the retractable fence 400 and slides in correspondence with one of the peripheral walls 300.
Specifically, when the retractable fence 400 moves and changes the inner width of the inner space of the computer case 100, the positioning component 600 moves as well. Take FIG. 3 and FIG. 4 as an illustration, when the positioning component 600 moves and drives the retractable fence 400 to extend or compress, the positioning component 600 slides on the outer space of one of the peripheral walls 300. The peripheral walls 300 further have a rail 340 corresponding to the positioning component 600, and the positioning component 600 reciprocates in the rail 340, so as to make the reciprocating of the retractable fence 400 more stable. The peripheral walls 300 further have an indentation 350, and the rail 340 is disposed in the indentation 350. More specifically, the positioning component 600 reciprocates in the rail 350 disposed in the indentation 350, such that the positioning component 600 does not protrude in the peripheral wall 300.
The positioning component 600 further includes a plurality of positioning grooves 610, and the peripheral wall 300 has a bump 330. When the retractable fence 400 moves to the appropriate position according to the width of the cooling module or the electronic component, users can embed the bump 330 into one of the positioning grooves 610 to fix the retractable fence 400. In other words, the retractable fence 400 can be fixed via the embedment of the bump 330 and the positioning grooves 610, such that the retractable fence 400 will not move by accidental touches.
Refer to FIG. 5. The computer case 100 includes two positioning components 600 disposed on the peripheral walls 300 in symmetry, so as to make a more stable fixed retractable fence 400. One end of each positioning component 600 is fixed on the second sidewall 500, and each positioning component 600 is located at the outer surface of the retractable fence 400 and slides in correspondence with the peripheral wall 300. The function of two positioning components 600 here is similar to that of the aforementioned positioning component 600, the inventor will not repeat here.
The second sidewall 500 includes a transparent portion 510, and the transparent portion 510 can be made of glass or transparent plastic, such that users can see the hardware inside the computer case 100. If the hardware crashes, users can quickly determine what the problem is and deal with it timely.
People having ordinary skill in the art can make proper modification to the computer case 100 according to the actual needs or design requirements, not limited as described herein.
Except for the better cooling performance, the computer case 100 of this disclosure is able to adjust the width of the inner space of the computer case 100 easily and fix the position of the retractable fence 400 via the embedment of the bump 330 of each peripheral wall 300 and the positioning grooves 610 in the positioning component 600, such that different specifications of the cooling module or electronic component can be installed in the computer case 100. Hence, the computer case 100 can reduce the cost of buying additional computer cases in the prior art when the cooling module or electronic component with different width is replaced.
Though the embodiments of this disclosure are disclosed as described above, this is not to limit this disclosure. People having ordinary skill in the art will recognize that this disclosure can be practiced with modification within the spirit and scope of the claim. It is therefore to be understood that this disclosure is not to be limited by the foregoing description but only by the appended claims.
