The opposite ends of these vertical support rods 23 are respectively connected to two second horizontal rods 114 located on the same side of the computer housing 10, and these vertical support rods 23 are parallel to these vertical rods 115. The opposite ends of these second support rods 24 are respectively connected to two vertical rods 115 located on the same side of the computer housing 10, and these second support rods 24 are parallel to these first horizontal rods 113.

[0100] In this embodiment, the length of the first support rods 22 is, for example, equal to the length of the vertical support rods 23, and the length of the vertical support rods 23 is, for example, equal to the length of the second support rods 24.

[0101] In this embodiment, the computer casing 10 may further include a plurality of fans 4.

The motherboard tray 6 is disposed in the internal space of the cuboid frame and fixed to the second support rod 24, and the fixing method is, for example, screw fastening.

[0103] Please see Figure 8 and Figure 9 . Figure 8 for Figure 7 A 3D diagram of the motherboard tray, and Figure 9 forFigure 7 Another perspective view of the motherboard tray. In this embodiment, the motherboard tray 6 includes a tray base plate 61, multiple L-shaped engaging portions 62 and 63, multiple tray fixing structures 64, and multiple tray fixing members 65.

[0104] In this embodiment, each of the L-shaped engaging portions 62 and 63 has a vertical portion 66 perpendicular to the tray base plate 61 and a parallel portion 67 parallel to the tray base plate 61. The vertical portion 66 connects to the tray base plate 61 and is perpendicular to it, serving as a vertical fixing component. The parallel portion 67 connects to the vertical portion 66 and is parallel to the tray base plate 61. These L-shaped engaging portions 62 and 63 can be distinguished by the length of the parallel portion 67. For example, the portion with a shorter parallel portion 67 is the L-shaped engaging portion 62, and the portion with a longer parallel portion 67 is the L-shaped engaging portion 63. In addition, the tray base plate 61 has multiple through holes, the arrangement of which can be matched with various sizes of mainboards. The tray base plate 61 also has multiple slots and openings; these structures are designed to facilitate the installation of the mainboard tray 6, or to pre-form it to save materials or reduce structural weight.

[0105] like Figure 9 As shown, in this embodiment, the tray fixing structures 64 are, for example, screw holes, and the tray fixing members 65 are, for example, screws. These tray fixing members 65 can pass through the tray fixing structures 64 to fix the motherboard tray 6 to the second support rod 24. The parallel portion 67 of the L-shaped engaging portion 62 contacts the outer side of the second support rod 24, while the parallel portion 67 of the L-shaped engaging portion 63 engages with the inner side of the second support rod 24. This differentiated fixing method of the two types of L-shaped engaging portions 62 and 63 ensures that the motherboard tray 6 can be securely and vertically installed on the second support rod 24, while the L-shaped hook structure effectively distributes and manages the force during installation. Thus, the L-shaped engaging portions 62 and 63 facilitate the installation of the motherboard and other components. Through the L-shaped engaging portions 62 and 63, during installation, the motherboard tray 6 can slide along the second support rod 24 and be adjusted to a predetermined position matching a specific motherboard specification, thereby allowing for flexible adjustment of the motherboard tray 6's position to meet the installation requirements of motherboards of different specifications.

[0107] In this embodiment, the computer chassis 10 may further include a GPU display adapter 8, and the GPU display adapter 8 is mounted on a GPU display adapter bracket 7. When installing the GPU display adapter 8, the GPU display adapter bracket 7 can support the weight of the GPU display adapter 8 and improve the stability of the GPU display adapter 8 installation.

[0108] Please see Figures 11 to 13 ,in Figure 11 for Figure 10 A magnified view from another perspective. Figure 12 for Figure 10 A 3D diagram of the GPU display adapter bracket, and Figure 13 for Figure 10 This is a perspective view of another GPU display adapter bracket. In this embodiment, the GPU display adapter bracket 7 includes a frame 71 and a support arm 72. The frame 71 includes a first side plate 711, a second side plate 712, and a tongue 715. The second side plate 712 and the tongue 715 are respectively connected to adjacent sides of the first side plate 711. The second side plate 712 is connected to one side of the first side plate 711 and is perpendicular to the first side plate 711. The tongue 715 is connected to the side of the first side plate 711 adjacent to the second side plate 712, and the tongue 715 is inclined toward the second side plate 712. The angle between the tongue 715 and the first side plate 711 is, for example, an obtuse angle. The first side plate 711 has a plurality of frame fixing structures 714, and these frame fixing structures 714 are, for example, screw holes. These frame fixing structures 714 allow fasteners (e.g., screws) to pass through to fix the GPU display adapter bracket 7 to the first horizontal member 113.

[0109] The support arm 72 includes a first plate portion 722, a second plate portion 723, and a buffer member 725. The first plate portion 722 is connected to the second plate portion 723 and is perpendicular to the second plate portion 723.

The second plate portion 723 abuts against a second side plate 712 and is perpendicular to the first side plate 711. The second plate portion 723 has a plurality of first fixing structures 724 and a plurality of second fixing structures 726. These first fixing structures 724 and second fixing structures 726 can be distinguished according to their distance from the first side plate 711. For example, the first fixing structure 724 is farther away from the first side plate 711, and the second fixing structure 726 is closer to the first side plate 711. These first fixing structures 724 and these second fixing structures 726 are, for example, screw holes.

[0110] In this embodiment, the GPU display adapter bracket 7 further includes a plurality of bracket fasteners 73. These bracket fasteners 73 are, for example, hand screws.

[0111] In this embodiment, the second side plate 712 further includes a groove 713. The groove 713 is parallel to the second plate portion 723. The bracket fasteners 73 pass through the groove 713 and the first fixing structure 724 to fix the second plate portion 723 to the second side plate 712. The groove 713 allows the support arm 72 to be adjusted vertically to any desired position so that the height of the GPU display adapter bracket 7 matches the height between the bottom of the GPU display adapter 8 and the bottom of the computer case 10. Furthermore, the second fixing structure 726 allows the support arm 72 to be closer to the center of the computer case 10, so that the position of the first plate portion 722 can accommodate GPU display adapters of different sizes. With this design, the height of the GPU display adapter bracket 7 can be adjusted to accommodate the vertical position of the GPU display adapter 8. The vertical direction can refer to... Figure 1 The bottom of the computer case 10 shown is in a vertical direction.

[0112] In the above embodiments, the fastener 13 is, for example, a screw, but is not limited thereto. In other embodiments, the fastener may also be replaced with a rivet.

[0113] In the above embodiments, these second fixing structures 122 are, for example, threaded holes, but are not limited thereto. In other embodiments, the second fixing structure may also be replaced with a fixing hole without threads.

[0114] In the above embodiments, these first fixing structures 112 may be, for example, threaded assembly holes or unthreaded assembly holes, and the present invention is not limited thereto.

[0115] In the above embodiment, the rod 11 is assembled with the corner assembly 12 via the fastener 13. However, this is not a limitation. In other embodiments, the rod may be assembled directly with the corner assembly without the fastener, for example, by snap-fit ​​or welding.

[0116] In the above embodiment, the length L1 of the first horizontal member 113 is greater than the length L2 of the second horizontal member 114 and approximately equal to the length L3 of the vertical member 115, but this is not a limitation. In other embodiments, the lengths of the members can be arbitrarily adjusted, for example, all of them can be equal.

[0117] In the above embodiments, the top plate 14, the bottom plate 15, and the front I / O panel 18 are screwed to the rod 11, but this is not a limitation. In other embodiments, the top plate, the bottom plate, and the front I / O panel may also be fixed to the rod in other ways, such as magnetically or by welding.

[0118] According to the above embodiment of the computer case, by changing the cuboid frame of the computer case to be composed of a first assembly of modular rods and a second assembly of corner assemblies, the process of manufacturing components can be eliminated and the assembly efficiency can be improved.

[0119] Furthermore, since manufacturers can assemble different styles of computer cases by combining rods made from the same mold and corner assemblies made from the same mold with different lengths, manufacturers can reduce the cost of mold development when producing different styles of computer cases.

[0120] Although the present invention has been disclosed above with reference to the foregoing embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present invention.
