Description

Technical Field

[0001] This utility model relates to the field of server chassis technology, and in particular to a screwless GPU mounting structure. Background Technology

[0002] With the development of high-performance computing and artificial intelligence, GPU module servers, due to their powerful parallel computing capabilities, have become critical infrastructure, widely used in scientific computing, deep learning, and other fields. However, the maintenance, upgrading, or troubleshooting of GPU module servers often requires disassembling and reassembling the GPU modules. Currently, this process mainly relies on manual operation, requiring the use of screwdrivers to tighten or loosen the screws between the GPU module and the chassis one by one.

[0003] This manual screw-driving method is not only frequent, tedious, and time-consuming, but it also easily leads to screws falling into gaps inside the server or onto the motherboard. If the fallen screws are not detected in time, they may come into contact with the circuit and cause a short circuit, which may damage components or even the motherboard.

[0004] Based on this, in order to optimize the ease of connection between existing GPU modules and motherboards, we propose a screwless GPU mounting structure. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the frequent, tedious, and time-consuming manual screw-driving methods, and to propose a screwless GPU fixing structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a screwless GPU mounting structure, including: The plug-in post and the unlocking post that is movably plugged into the plug-in post; The connector has a stop at its head end, and at least one stop bead is radially movably inserted into the lower part of the connector. The stop is positioned above the GPU module housing, and the stop bead is positioned below the connection surface of the chassis. The unlocking post has an annular groove on its outer side, and the stop bead slides against the outer wall of the unlocking post and can be stored in the annular groove.

[0007] Furthermore, the insertion post has a stepped hole inside, and the upper side of the unlocking post has an inwardly recessed portion. A spring is placed between the inwardly recessed portion and the opposite surface of the stepped hole, and the spring is sleeved on the outside of the inwardly recessed portion.

[0008] Furthermore, a rotating ring is rotatably connected to the top of the unlocking post, and at least a portion of the rotating ring stops on the outside of the insertion post.

[0009] Furthermore, a snap-fit ​​assembly is provided on the outer side of the swivel ring, and the snap-fit ​​assemblies on multiple plug posts are connected together by an integrated plate.

[0010] Furthermore, the snap-fit ​​assembly includes a connecting post formed on the end face of the swivel ring and a frustum formed on the upper end of the connecting post; A deformation groove is provided on the end face of the frustum portion along the axial direction, extending into the connecting column. A straight slot hole is provided on the end face of the integrated plate. The straight slot hole is engaged with the outside of the connecting column and stops below the frustum portion.

[0011] Furthermore, the outer side of the stop portion has an anti-slip portion, and a washer is provided on the outer side of the plug post and below the stop portion.

[0012] Furthermore, the stop portion and the insertion post are threadedly connected.

[0013] The present invention proposes a screwless GPU mounting structure with the following advantages: By using a plug-in post to replace bolts, when the GPU module is installed on the motherboard of the chassis, the outer shell of the GPU module and the connecting surface of the chassis are in contact. At this time, the plug-in post can be inserted into the reserved holes in the outer shell and the connecting surface. The stop part and the upper side of the outer shell provide a stop, and the stop ball limits the connection below the connecting surface. This achieves convenient connection and locking between the GPU module and the chassis, while meeting the needs of convenient disassembly of the GPU module and the chassis. The overall structure design is simple and optimizes the assembly convenience of the server chassis. In addition, multiple fixed structures can be connected together through an integrated plate, which optimizes connection stability and avoids the problem of individual fixed structures falling off.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 As one embodiment of this utility model, a screwless GPU fixing structure is disclosed. Specifically, the GPU module fixing structure includes a plug 1 and an unlocking post 2 that is movably plugged into the plug 1. The upper end of the unlocking post 2 protrudes from the upper surface of the plug 1. The plug 1 has a stop portion 11 at its head end, and at least one stop bead 12 is radially movably inserted into the lower part of the plug 1. The stop portion 11 stops above the GPU module housing, and the stop bead 12 stops below the connection surface of the chassis. The unlocking post 2 has an annular groove 21 on its outer side, and the stop bead 12 slides against the outer wall of the unlocking post 2 and can be stored in the annular groove 21.

[0018] In other words, by using the plug-in post 1 to replace the bolt in this utility model, when the GPU module is installed on the motherboard of the chassis, the outer shell of the GPU module and the connecting surface of the chassis are in contact. At this time, the plug-in post 1 can be inserted into the reserved hole in the outer shell and the connecting surface. The stop part 11 and the upper side of the outer shell provide a stop, while the stop bead 12 limits it to the lower part of the connecting surface. At this time, a convenient connection and locking between the GPU module and the chassis can be achieved.

[0019] In some embodiments, the insertion post 1 of this utility model has a stepped hole 13 formed inside. The stepped hole 13 has a structural design with a small upper diameter and a large lower diameter. The upper side of the unlocking post 2 has an inwardly recessed portion 22. The inwardly recessed portion 22 is adapted to the upper diameter of the stepped hole 13. A spring 23 is placed between the opposite surfaces of the inwardly recessed portion 22 and the stepped hole 13. The spring 23 is sleeved on the outside of the inwardly recessed portion 22. The spring 23 is used to control the unlocking post 2 to reset after it is pulled.

[0020] Of course, in order to limit the upper side of the unlocking post 2 and prevent the unlocking post 2 from sliding downward and disengaging from the plug post 1, the top of the unlocking post 2 in this embodiment is also rotatably connected to a rotating ring 24. At least part of the rotating ring 24 stops on the outside of the plug post 1. In this embodiment, the rotating ring 24 is set as a semi-circular structure and is plate-shaped.

[0021] In other words, in the actual locked state, the outer wall of the unlocking post 2 abuts against the stop bead 12 and moves outward along the bead hole on the insertion post 1. In this embodiment, the bead hole is formed on the outside of the unlocking post 2, and its outer diameter is smaller than the diameter of the stop bead 12, so as to prevent the stop bead 12 from falling outward. When the stop bead 12 protrudes outward, its stop is below the mounting surface of the chassis, and together with the stop part 11 mentioned above, it is used to fix the connection between the GPU module and the chassis.

[0022] When unlocking is required, the aforementioned rotating ring 24 can be rotated. At this time, the rotating ring 24 can be moved outward, and the rotating ring 24 drives the entire unlocking post 2 to move outward until the stop bead 12 slides to the opposite position of the ring groove 21. At this time, since the stop bead 12 has inward sliding space, when the entire plug post 1 is pulled upward, the stop bead 12 can retract inward. In this way, the entire plug post 1 can be separated from the GPU module and the chassis to meet the purpose of convenient disassembly and reassembly between the GPU module and the chassis.

[0023] Of course, the above descriptions are all based on a single fixed structure. Since multiple GPU modules are generally required to be installed in the chassis, in order to combine multiple individual fixed structures into a whole for easy overall operation, in this embodiment, a snap-fit ​​component 3 is provided on the outside of the rotating ring 24, and an integrated board 4 is connected between the snap-fit ​​components 3 on multiple plug pins 1.

[0024] Specifically, in this embodiment, the snap-fit ​​assembly 3 includes a connecting post 31 formed on the end face of the rotating ring 24 and a frustum portion 32 formed on the upper end of the connecting post 31. The end face of the frustum portion 32 is provided with a deformation groove 33 that extends through the connecting post 31 along the axial direction. The end face of the integrated plate 4 is provided with a straight slot hole 41, which is engaged with the outside of the connecting post 31 and stops below the frustum portion 32.

[0025] In this embodiment, an integrated plate 4 is used to connect the rotating rings 24 on multiple fixed structures in sequence, thus enabling overall operation. This not only optimizes the convenience of operation but also reduces the possibility of losing fixed structures. During connection, the frustum 32 deforms through the deformation groove 33, and then the integrated plate 4 passes through the frustum 32 and is inserted into the straight slot hole 41. This facilitates the formation of multiple fixed structures into a whole. It should be noted that the rotating rings 24, connecting posts 31, and frustum 32 in this embodiment are integrally molded and can all be made of plastic to provide elastic force. Furthermore, it should be noted that in this embodiment, two snap-fit ​​components 3 can be installed on the end face of each of the rotating rings 24 to ensure the connection stability with the integrated plate 4. Of course, since this embodiment uses a claw structure composed of a connecting post 31 and a frustum 32 for connection, the integrated plate 4 and the snap-fit ​​components 3 can also be separated to achieve a single operation on a single fixed structure.

[0026] In some embodiments, the outer side of the stop portion 11 in this invention has an anti-slip portion, and a washer 14 is provided on the outer side of the insertion post 1 and below the stop portion 11. Of course, the washer 14 is a silicone washer.

[0027] It should be noted that in this embodiment, the stop part 11 and the plug post 1 are threadedly connected. The threaded connection allows for adjustment of the clamping distance between the stop part 11 and the stop bead 12, thereby enabling adjustment of the clamping force to meet the fixing requirements of different preload forces.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
