Description

Technical Field

[0001] This utility model belongs to the technical field of computer chassis, specifically relating to a modular computer chassis that is easy to assemble quickly. Background Technology

[0002] A computer case is an outer shell used to house computer hardware, primarily serving to protect components, shield electromagnetic radiation, and aid in heat dissipation. Early cases were mainly made of metal, with a focus on practicality. With technological advancements, materials now include steel, aluminum, and plastic, and designs are more personalized, featuring side windows and modular designs. Internally, it requires a well-organized layout of components such as the motherboard, power supply, and hard drives, and cooling structures have evolved from simple fans to complex systems compatible with water cooling. From AT to ATX and ITX form factors, the case has continuously adapted to hardware upgrades and user needs, serving as a crucial platform for PC hardware integration.

[0003] Traditional computer cases have fixed internal space, making them unable to accommodate increasingly longer graphics cards (such as the RTX 4090, which is over 350mm long) and diverse hardware dimensions. Users often need to replace the entire case when upgrading their graphics card, which is costly and cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide a modular computer chassis that is easy to assemble quickly, in order to solve the problem that the internal space of traditional chassis is fixed and cannot accommodate the ever-increasing length of graphics cards (such as the RTX 4090, which is over 350mm long) and diverse hardware sizes. Users often need to replace the entire chassis when upgrading their graphics cards, which is costly and cumbersome.

[0005] question.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a modular computer chassis that is easy to assemble quickly, comprising a front chassis shell and a rear chassis shell disposed on the outside of the rear side of the front chassis shell; The front and rear chassis are respectively provided with rear heat dissipation panels on the left side, the lower side of the front and rear chassis are respectively provided with lower heat dissipation panels, the front side of the front and rear chassis are respectively provided with glass panels, and the front front right side of the front chassis is provided with a front panel. The inner side of the rear heat dissipation panel is provided with multiple internal component connection slots, the rear end of the upper heat dissipation panel of the rear chassis is provided with a switch connection component, and the rear side of the rear chassis is provided with a locking block for limiting the front chassis. The lower heat dissipation panel of the front chassis has two fixing blocks on the upper middle rear end sides. A rotating rod is movably connected to the inner side of the fixing block. A driving rod is movably connected to the end of the rotating rod. A connecting block is movably connected to the lower end of the driving rod. A slider is provided on the lower side of the connecting block. A threaded rod is threadedly connected to the inner middle side of the connecting block. The threaded rod is provided with fixing plates at both ends, and a slide rail is provided at the connection between the slider and the lower heat dissipation panel.

[0007] Preferably, the rear end of the threaded rod is connected to the fixed plate via a nested connection, and the threaded rod can rotate within the fixed plate.

[0008] Preferably, the threaded rod passes through the front fixing plate, and the fixing plates at both ends are respectively fixedly connected to the lower heat dissipation panel.

[0009] Preferably, the two fixing blocks and the lower heat dissipation panel are fixedly connected, and the rotating rod can rotate within the two fixing blocks.

[0010] Preferably, the drive rod can rotate at the end of the rotating rod to form an upward bulge shape, and the connecting block can rotate at the end of the drive rod.

[0011] Preferably, the connecting block can move back and forth under the threaded drive of the threaded rod, and the connecting block can move back and forth within the slide rail via a slider.

[0012] Preferably, the front chassis housing is connected to the rear chassis housing via a nested connection, and the front chassis housing can move back and forth within the rear chassis housing.

[0013] Compared with the prior art, this utility model provides a modular computer chassis that is easy to assemble quickly, and has the following beneficial effects: 1. Traditional computer cases have fixed internal space, often requiring a complete system replacement to accommodate increasingly longer graphics cards (such as the RTX 4090, which is over 350mm long). This design, through the sliding adjustment of the front and rear case shells, expands the internal depth by 5-10cm, easily accommodating graphics cards with lengths of 300-400mm. Users do not need to replace the entire case to upgrade their graphics cards, significantly reducing hardware upgrade costs.

[0014] 2. High-end graphics cards (such as the AMD RX 7900 XTX) weigh over 3kg, and prolonged suspension can easily lead to metal fatigue and breakage of the PCIe slot. This support structure distributes the weight of the graphics card to the bottom of the case through mechanical transmission, reducing the stress on the slot and preventing poor contact of the gold fingers due to the graphics card sagging.

[0015] Furthermore, through the precise fit between the threaded rod and the threaded pair, the support platform can achieve height adjustment accuracy to accommodate graphics cards of different thicknesses. Users only need to rotate the threaded rod 2-3 turns to complete the adaptation, requiring no additional tools, making the operation simple and quick. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-5 The modular computer chassis shown is easy to assemble quickly, including a front chassis shell 1 and a rear chassis shell 2 disposed on the outside of the rear side of the front chassis shell 1; The front chassis 1 and the rear chassis 2 are respectively provided with a rear heat dissipation panel 3 on the left side, the front chassis 1 and the rear chassis 2 are respectively provided with a lower heat dissipation panel 6 on the lower side, the front chassis 1 and the rear chassis 2 are respectively provided with a glass panel 9 on the front side, and the front panel 5 is provided on the front right side of the front chassis 1. Multiple internal component connection slots 4 are provided on the inner side of the rear heat dissipation panel 3, and a switch connection component 8 is provided inside the rear end of the upper heat dissipation panel 7 of the rear chassis 2. A locking block 11 for limiting the front chassis 1 is provided inside the rear side of the rear chassis 2. The lower heat dissipation panel 6 of the front chassis 1 has two fixing blocks 14 on the upper middle rear end. The inner side of the fixing block 14 is movably connected to the rotating rod 12. The end of the rotating rod 12 is movably connected to the driving rod 10. The lower end of the driving rod 10 is movably connected to the connecting block 15. The lower side of the connecting block 15 has a slider 18. The middle inner side of the connecting block 15 is threadedly connected to the threaded rod 16. Fixed plates 13 are provided at both ends of the threaded rod 16, and a slide rail 17 is provided at the connection between the slider 18 and the lower heat dissipation panel 6.

[0024] The front chassis housing 1 is connected to the rear chassis housing 2 by a nested connection, and the front chassis housing 1 can move back and forth within the rear chassis housing 2.

[0025] In this embodiment, the user can directly insert and fix devices such as cooling fans and water cooling radiators into the internal component connection slots 4 of the rear heat dissipation panel 3 to achieve a modular heat dissipation layout.

[0026] After the user has finished installing the internal components of the chassis, slide the front chassis shell 1 backward along the interlocking structure of the rear chassis shell 2 until the locking block 11 engages with the corresponding slot of the front chassis shell 1, thus completing the assembly of the chassis body.

[0027] The glass panel 9 and the front panel 5 are fixed to the front and right sides of the front chassis housing 1 respectively by means of clips or magnetic attraction, thus completing the external encapsulation.

[0028] The motherboard can be mounted on the pre-drilled holes in the rear chassis 2 using a motherboard bracket, and then secured with standard screws.

[0029] After inserting the graphics card into the motherboard PCIe slot, adjust the position of the graphics card to align it with the graphics card support on the rear case 2, and then secure it directly with screws.

[0030] The power supply is installed in the power supply compartment of the rear chassis 2, and the hard drive / SSD is fixed through the reserved slot on the lower heat dissipation panel 6.

[0031] like Figure 1-5As shown, the rear end of the threaded rod 16 is connected to the fixed plate 13 by a nested connection, and the threaded rod 16 can rotate within the fixed plate 13. The threaded rod 16 passes through the front fixed plate 13. The two fixed plates 13 at both ends are fixedly connected to the lower heat dissipation panel 6, and the two fixed blocks 14 are fixedly connected to the lower heat dissipation panel 6. The rotating rod 12 can rotate within the two fixed blocks 14. The driving rod 10 can rotate at the end of the rotating rod 12 to form an upward bulging shape. The connecting block 15 can rotate at the end of the driving rod 10. The connecting block 15 can move back and forth under the threaded drive of the threaded rod 16. The connecting block 15 can move back and forth within the slide rail 17 via the slider 18.

[0032] Preferably, when users need to install an extra-long graphics card (such as 350mm or more), the front chassis shell 1 can be slid back 5-10cm to increase the internal depth space.

[0033] This structure primarily adjusts the internal volume by sliding to accommodate graphics cards of different lengths (e.g., a standard 300mm graphics card uses the initial position, while extra-long graphics cards need to be slid back for expansion), avoiding the problem of having to replace the entire system due to insufficient space in traditional cases.

[0034] Preferably, before installing the graphics card, the user can use a screwdriver to rotate the threaded rod 16 (the operating end is exposed at the front fixing plate 13), and the connecting block 15 moves backward under the thread drive, causing the drive rod 10 and the rotating rod 12 to bulge upward, forming a graphics card support platform.

[0035] Users can adjust the number of rotations of the threaded rod 16 according to the thickness of the graphics card to make the height of the support platform flush with the bottom of the graphics card.

[0036] After inserting the graphics card into the slot, place the bottom directly on the support platform and then secure it with screws.

[0037] The structure mainly converts rotary motion into linear motion through the threaded pair (lead 2mm) between the threaded rod 16 and the connecting block 15, and the limiting position of the slider 18 within the slide rail 17 ensures motion stability.

[0038] The rotating rod 12 and the drive rod 10 are hinged to form a deformable parallelogram, which keeps the platform level during movement and avoids uneven force on the graphics card.

[0039] The support platform helps distribute the weight of the graphics card (especially high-end graphics cards weighing over 3kg), reducing the stress on the PCIe slots, lowering the risk of slot damage due to long-term gravity, and preventing poor contact caused by graphics card sagging.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
