As shown in FIG. 1 to FIG. 4, the computer host case structure 1 of the first embodiment of the present invention can be a case of a desktop computer for fastening an electronic device 100. The electronic device 100 of the present invention can be a hard disk drive, but the type of the electronic device 100 is not limited to that application; it can also be a CD-ROM drive or other device that can be installed in the desktop computer. The number of the electronic devices 100 is not limited to one; the number can be changed according to varied requirements. The computer host case structure 1 includes a main body 10, a pivot part 70, two pivot structures 20, an electronic device fastening set 30, two pivot axes 40, three buffer units 50, and two fastening parts 60.
In the first embodiment of the present invention, the main body 10 is used for containing the internal components of the computer, such as a motherboard, a power system, and the hard disk drive of the electronic device 100. The main body 10 may have the fastening structures in the position of the internal components for fastening the internal components. The pivot part 70 is connected to the main body 10. The two pivot structures 20 respectively include a notch 21, a pivot hole 22, and an opening 23. The pivot hole 22 is connected to the notch 21 and the opening 23. The two pivot structures 20 of the first embodiment are located on the pivot part 70.
As shown in FIG. 2 and FIG. 6, in the first embodiment of the present invention, the electronic device fastening set 30 includes two fixing parts 31 and two fastening units 32. The two sides of the electronic device 100 are fastened by the fixing parts 31. The surface of the electronic device 100 that contacts the fixing part 31 may be designed to have a cushion with a buffer effect to prevent the electronic device 100 from being scratched, and the cushion may absorb the external force to achieve a cushioning effect. However, the number of the fixing parts 31 is not limited to two; the number can be changed according to the number of the electronic devices 100. The fastening unit 32 is a circular cavity for fastening the fastening part 60.
As shown in FIG. 4, FIG. 5, and FIG. 7 to FIG. 10, in the first embodiment of the present invention, the two pivot axes 40 are located on the electronic device fastening set 30 for pivotally connecting to the pivot hole 22 of the pivot structure 20 respectively; the electronic device fastening set 30 can rotate via the pivotal connection between the two pivot axes 40 and the pivot structure 20. The pivot axis 40 includes two long sides 41 and two arc sides 42. The distance between the two long sides 41 is corresponded to the size of the notch 21 and the opening 23. The distance between the two arc sides 42 is corresponded to the size of the pivot hole 22. When the electronic device fastening set 30 moves, the long side 41 of the pivot axis 40 becomes aligned with the opening 23 such that the pivot axis 40 can easily enter the opening 23 from the outside, allowing the pivot axis 40 to enter the pivot hole 22. When the electronic device fastening set 30 rotates to a specific angle A relative to the main body 10, the long side 41 of the pivot axis 40 becomes aligned with the notch 21, and the pivot axis 40 can enter the notch 21. The arc side 42 of the pivot axis 40 can rotate in the pivot hole 22. The specific angle A of the present invention is 90° substantially; however, the angle of the specific angle A is not limited to that design, for the specific angle A can be changed according to varied requirements. According to the experiment of the present invention, the specific angle A is preferred to be in a range of 70° to 100°.
As shown in FIG. 4, in the first embodiment of the present invention, three buffer units 50 are located on the pivot part 70. The buffer unit 50 includes an arcuate portion 51 and a stopper portion 52. The arcuate portion 51 contacts the electronic device fastening set 30 for providing friction to the electronic device fastening set 30, such that when the user adjusts the position of the electronic device fastening set 30, the electronic device fastening set 30 is prevented from generating any violent shaking that could affect the electronic device 100 fastened by the electronic device fastening set 30. The stopper portion 52 is used for allowing the electronic device fastening set 30 to limit the movement of the electronic device fastening set 30 when the pivot axis 40 enters the notch 21. However, the number of the buffer units 50 of the present invention is not limited to three; according to the actual experiment of the present invention, if the number of the buffer units 50 is more than two, the buffer effect will be sufficiently provided to a preferred degree; however, if the number of the buffer units 50 is one, a slight buffer effect will still be provided; therefore, the number of the buffer units 50 can be changed according to varied requirements.
As shown in FIG. 4, FIG. 6 and FIG. 9, in the first embodiment of the present invention, the two fastening parts 60 are located on the pivot part 70. Each fastening part 60 includes a fastening point 61. The fastening point 61 is a circular convex dot for fastening the fastening unit 32 of the electronic device fastening set 30. When the electronic device fastening set 30 rotates to the specific angle A relative to the main body 10, the pivot axis 40 enters the notch 21, and the circular convex dot of the fastening point 61 also moves to the circular cavity of the fastening unit 32, such that the fastening point 61 of the fastening part 60 can be fastened to the fastening unit 32 of the electronic device fastening set 30. However, the number of the fastening parts 60 of the present invention is not limited to two.
When the user wants to apply the computer host case structure 1 of the present invention to install the electronic device 100, as shown in FIG. 2, the user can fasten the fixing part 31 of the electronic device fastening set 30 to the two sides of the electronic device 100. Then, as shown in FIG. 5, FIG. 7, and FIG. 8, the user can adjust the angle of the electronic device fastening set 30 which fastens to the electronic device 100, allowing the long side 41 of the pivot axis 40 to become aligned with the opening 23 such that the pivot axis 40 can smoothly pass through the opening 23 into the pivot hole 22, whereby the pivot axis 40 can be pivotally connected to the pivot structure 20, and the electronic device fastening set 30 can rotate relative to the main body 10 via the pivotal connection between the pivot axis 40 and the pivot structure 20. Then, as shown in FIG. 4, FIG. 11, and FIG. 12, the user can rotate the electronic device fastening set 30 which is fastened to the electronic device 100 toward the main body 10; during the rotation, the arcuate portion 51 of the three buffer units 50 contacts the electronic device fastening set 30 to provide friction to the electronic device fastening set 30 to avoid rotation that could generate shaking that in turn could affect the electronic device 100 fastened by the electronic device fastening set 30. The electronic device fastening set 30 can rotate to be completely contained in the main body 10 (as shown in FIG. 12), such that the assembly and installation of the electronic device 100 and the computer host case structure 1 can be completed.
If the electronic device 100 needs to be repaired, then as shown in FIG. 4 to FIG. 6, FIG. 9, and FIG. 10, the user can rotate the electronic device fastening set 30 to the specific angle A relative to the main body 10. At this moment, the long side 41 of the pivot axis 40 becomes aligned with the notch 21, allowing the pivot axis 40 to enter the notch 21. Because the distance between the two long sides 41 is corresponded to the size of the notch 21, the pivot axis 40 can be in the notch 21 stably and be unable to rotate. When the pivot axis 40 enters the notch 21, the circular convex dot of the fastening point 61 moves to the circular cavity of the fastening unit 32, and the stopper portion 52 limits the movement of the electronic device fastening set 30. Therefore, via the combination of the entering of the pivot axis 40 to the notch 21, the fastening between the circular convex dot of the fastening point 61 and the circular cavity of the fastening unit 32, and the limiting of movement by the stopper portion 52 of the electronic device fastening set 30, the electronic device fastening set 30 connected to the pivot axis 40 can be positioned stably. Therefore, the maintenance worker can disassemble the fixing part 31 to remove the electronic device 100 from the electronic device fastening set 30 in preparation for repairing the electronic device 100.
Via the computer host case structure 1 of the present invention, the user can install the electronic device 100 easily and quickly. If the user needs to fix or replace the electronic device 100, via the design of the notch 21 of the pivot structure 20, the buffer unit 50 and the fastening part 60, the user can remove the electronic device fastening set 30 from the electronic device 100 easily without causing any shaking, such that the electronic device 100 will not be damaged. In addition, the computer host case structure 1 of the present invention does not have the screws and screw holes of the prior art, so the cost can be reduced.
Please refer to FIG. 13, which illustrates the second embodiment of the present invention. FIG. 13 illustrates a partial schematic drawing of the separated pivot part and the electronic device fastening set of the second embodiment of the present invention.
As shown in FIG. 13, the second embodiment differs from the first embodiment of the present invention in that, in the second embodiment, the pivot structure 20a is located on the electronic device fastening set 30, and the pivot axis 40a is located on the pivot part 70; the electronic device fastening set 30 can rotate via the pivotal connection between the pivot axis 40a and the pivot structure 20a. 
It is noted that the above-mentioned embodiments are only for illustration. It is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents. Therefore, it will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention.
