Description

Technical Field

[0001] This application relates to the field of server structural design technology, and in particular to a limiting component for constraining the tail of a graphics processor and a server. Background Technology

[0002] In server architecture, vertically mounted GPUs (graphics processing units) are widely used in high-density servers due to their high space utilization. The head of a vertically mounted GPU is connected to a slot on the motherboard via gold fingers, while the tail of the vertically mounted GPU is mainly fixed by a tail fixing component. Existing tail fixing components include a tail bracket and a tail crossbeam, which are relatively complex in structure.

[0003] Because internal space in servers is extremely valuable, too many fixed structures can restrict the placement of other components, seriously affecting the overall design and performance of the server. In addition, during transportation, vertically inserted GPUs still have the problem of slight shaking or jumping, which can cause poor contact between the gold fingers and the slots on the motherboard. Utility Model Content

[0004] This application provides a limiting component and server for constraining the tail of a graphics processing unit (GPU) to at least solve the problem in the related art where the tail fixing component of a vertically inserted GPU is relatively complex, which seriously affects the overall design and performance of the server, and there is a problem of GPU tail shaking or jumping.

[0005] This application provides a limiting component for constraining the tail of a graphics processor, including a support beam and multiple clamping groups. The support beam is connected to the top cover of a server and extends along the arrangement direction of multiple graphics processors. Each clamping group is movably connected to the support beam, allowing the position of each clamping group on the support beam to be adjustable. Each clamping group includes two clamping structures arranged in pairs. At least two clamping structures in the same clamping group are used to clamp and limit the tail of the same graphics processor on both sides. The clamping structures slide against the support beam. The support beam has a trapezoidal cross-section along its length, with the larger end face of the trapezoidal support beam facing the graphics processor side and the smaller end face facing the top cover, so that the larger end face of the support beam and both sides of the support beam in the width direction form guide rails. The clamping structures have guide grooves for engaging with the guide rails.

[0006] In an exemplary embodiment, the clamping structure includes a slider and a clamping block, wherein the slider slides in engagement with a support beam; the clamping block is connected to the slider and extends in a direction away from the support beam, and the extension direction is perpendicular to the support beam; the clamping block has a clamping surface, and the two clamping surfaces of the two clamping structures arranged in pairs are arranged opposite to each other to effectively clamp the two side surfaces of the tail portion of the graphics processor; wherein the surface of the slider away from the clamping block has a guide groove, and the cross-sectional shape of the guide groove in the sliding direction of the slider is adapted to the guide rail to constrain the slider to slide only in engagement with the support beam.

[0007] In one exemplary embodiment, the limiting component further includes a fastener for securing the clamping structure when it slides into place, thereby enabling the clamping structure to effectively clamp the graphics processor.

[0008] In one exemplary embodiment, a locking hole is provided on the bottom surface of the guide slide, a fastener is provided through the locking hole, and the fastener is threadedly engaged with the locking hole so that when the clamping structure slides into place, the fastener is tightened so that the end of the fastener abuts against the surface of the support beam facing the graphics processor.

[0009] In one exemplary embodiment, the clamping structure is detachably connected to the support beam.

[0010] In one exemplary embodiment, at least the surface of the support beam facing the graphics processor is flat to allow for effective contact with the tail end face of the graphics processor.

[0011] In one exemplary embodiment, two clamping structures in the same clamping group are independently disposed on the support beam, and the positions of the two clamping structures in the same clamping group on the support beam are adjustable to adjust the clamping distance between the two clamping structures; to adapt to graphics processors of different widths; and / or to adapt to the widths of at least two adjacent graphics processors.

[0012] In one exemplary embodiment, the limiting component further includes a cushioning pad disposed on the clamping surface.

[0013] In one exemplary embodiment, the clamping structure is L-shaped, with two clamping structures arranged back to back, and the clamping surface is planar.

[0014] This application also provides a server, including a chassis base, a top cover, a motherboard, multiple graphics processors, and a limiting component. The chassis base has a receiving groove; the top cover is disposed at the opening of the receiving groove and is detachably connected to the chassis base; the motherboard is disposed within the receiving groove; the heads of the multiple graphics processors are all plugged into the motherboard; the support beam of the limiting component is detachably connected to the surface of the top cover facing the receiving groove; multiple clamping groups of the limiting component are movably connected to the support beam, and at least two clamping structures in each clamping group are used to clamp and limit the tail sides of the same graphics processor. The limiting component is the aforementioned limiting component.

[0015] This application provides a limiting component for constraining the tail of a graphics processor, including a support beam and multiple clamping groups. The support beam is connected to the top cover of a server and extends along the arrangement direction of multiple graphics processors. Each clamping group is movably connected to the support beam, allowing its position on the support beam to be adjustable. Each clamping group includes two clamping structures arranged in pairs. At least two clamping structures in the same clamping group are used to clamp and limit the tail of the same graphics processor on both sides. The clamping structures slide against the support beam. The support beam has a trapezoidal cross-section along its length, with the larger end face of the trapezoidal support beam facing the graphics processor side and the smaller end face facing the top cover, so that the larger end face of the support beam and both sides of the support beam in the width direction form guide rails. The clamping structures have guide grooves for engaging with the guide rails.

[0016] By connecting the support beam to the server's top cover and extending it along the arrangement direction of multiple graphics processors, and with multiple clamping groups movably connected to the support beam, the position of each clamping group on the support beam can be adjusted to accommodate graphics processors at different locations. This effectively clamps and limits the graphics processors at their corresponding positions. Furthermore, two clamping structures in the same clamping group can clamp and limit at least both sides of the tail of the same graphics processor, ensuring the reliability of clamping the tail of the graphics processor. During server transportation or operation, this effectively prevents the tail of the graphics processor from shaking or jumping due to poor fixation, thus ensuring the reliability of the connection between the graphics processor and the motherboard, and consequently ensuring the server's operational stability and transportation safety.

[0017] Furthermore, this application ensures the reliability and smoothness of the sliding of the slide rail on the support beam by sliding the clamping structure with the support beam. The cross-section of the support beam in its length direction is trapezoidal, with the large end face of the trapezoidal support beam facing the graphics processor side and the small end face facing the top cover, so that the large end face of the support beam and both sides in the width direction of the support beam form guide rails. The clamping structure has guide grooves for cooperating with the guide rails, ensuring the convenience and reliability of the sliding cooperation between the clamping structure and the support beam. In this way, by setting the cross-section of the support beam in its length direction to a trapezoidal structure, the support beam itself serves as both a beam and a guide rail. This ensures that the support beam does not occupy a large installation space in the height direction of the receiving slot, while also ensuring that the structure of the support beam is simple enough, thereby reducing the manufacturing difficulty of the limiting components and further ensuring the economy of the server.

[0018] Furthermore, the limiting component provided in this application has a relatively simple structure, and the supporting beam is connected to the top cover of the server, which will not occupy a large space in the server's receiving slot. Attached Figure Description

[0032] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] The embodiments of this application provide a limiting component and server for constraining the tail of a graphics processor. The device is described in detail below in conjunction with the structure and working principle of the limiting component and server for constraining the tail of a graphics processor (the technical terms involved must be explained).

[0034] It should be noted that in this application, the server includes a chassis base, a top cover 2, a motherboard 3, multiple graphics processors 4, and a limiting component 5. The chassis base has a receiving groove; the top cover 2 is disposed on the opening of the receiving groove and is detachably connected to the chassis base; the motherboard 3 is disposed in the receiving groove; the heads of the multiple graphics processors 4 are all plugged into the motherboard 3; the support beam 10 of the limiting component 5 is detachably connected to the surface of the top cover 2 facing the receiving groove; multiple clamping groups 20 of the limiting component 5 are movably connected to the support beam 10, and at least two clamping structures 21 in each clamping group 20 are used to clamp and limit the tail sides of the same graphics processor 4. The limiting component 5 is the limiting component described above and below.

[0035] Furthermore, the top cover 2 is secured to the chassis base using I-beams and a cover lock, forming a stable and fixed connection between the top cover 2 and the chassis base. Technically, the combined use of the I-beams and cover lock provides additional structural stability and rapid installation capability. In principle, the I-beams, as a connecting component, ensure a firm connection between the top cover 2 and the chassis base, while the cover lock allows for opening and closing without compromising structural integrity, facilitating maintenance and inspection. In terms of effectiveness, this connection method not only ensures the stability of the top cover 2 but also simplifies the installation process and improves efficiency. In other embodiments, the same fixing effect can be achieved through welding, bonding, or other types of locks, suitable for different production environments and usage requirements.

[0036] Furthermore, the fixing mechanism between the top cover 2 and the chassis base effectively transfers the constraint force of the graphics processor 4's rear fixing device to the chassis base, enhancing the overall structural stability. Technically, the fixing of the top cover 2 and the chassis base employs a multi-point contact and evenly distributed fixing point design, ensuring the uniform transmission of constraint force. In principle, when the graphics processor 4's rear fixing device applies a constraint force to the graphics processor 4, these forces are transmitted to the chassis base through the structure of the top cover 2 and the supporting beam 10, further stabilizing the position of the graphics processor 4 due to the chassis's rigid structure. In terms of effectiveness, this design allows the graphics processor 4 to remain in place even under severe vibration, reducing the potential failure rate. In other embodiments, the overall structural stability can be further improved by optimizing the contact area between the top cover 2 and the chassis or by adding additional support structures.

[0037] It should be noted that in this application, the limiting component effectively clamps the tail of the vertically inserted graphics processor 4.

[0038] like Figures 1 to 5 As shown, the limiting component constraining the tail of the graphics processor includes a support beam 10 and multiple clamping groups 20. The support beam 10 is used to connect to the top cover 2 of the server and extends along the arrangement direction of the multiple graphics processors 4. The multiple clamping groups 20 are all movably connected to the support beam 10 so that the position of each clamping group 20 on the support beam 10 can be adjusted. Each clamping group 20 includes two clamping structures 21 arranged in pairs. The two clamping structures 21 in the same clamping group 20 It is used at least to clamp and limit the tail sides of the same graphics processor 4; the clamping structure 21 is slidably engaged with the support beam 10; the cross section of the support beam 10 in its length direction is trapezoidal, and the large end face of the trapezoidal support beam 10 faces the graphics processor 4, and the small end face of the support beam 10 faces the top cover 2, so that the large end face of the support beam 10 and the two sides of the support beam 10 in the width direction form guide rails 11; the clamping structure 21 has guide grooves for engaging with the guide rails 11.

[0039] By connecting the support beam 10 to the server's top cover 2 and extending it along the arrangement direction of multiple graphics processors 4, and by movably connecting multiple clamping groups 20 to the support beam 10, the position of each clamping group 20 on the support beam 10 can be adjusted to adapt to different positions of the graphics processors 4, effectively clamping and limiting the graphics processors 4 at corresponding positions. In addition, the two clamping structures 21 in the same clamping group 20 can achieve the purpose of clamping and limiting at least both sides of the tail of the same graphics processor 4, ensuring the clamping reliability of the tail of the graphics processor 4. During server transportation or server operation, it can effectively prevent the tail of the graphics processor 4 from shaking or jumping due to poor fixation, thereby ensuring the connection reliability of the graphics processor 4 and the motherboard 3, and thus ensuring the operational stability and transportation safety of the server.

[0040] Furthermore, the sliding engagement between the clamping structure 21 and the support beam 10 ensures the reliability and smoothness of the sliding of the slider 211 on the support beam 10. The cross-section of the support beam 10 in its length direction is trapezoidal, with the large end face of the trapezoidal support beam 10 facing the graphics processor 4 and the small end face facing the top cover 2, so that the large end face of the support beam 10 and both sides of the support beam 10 in the width direction form guide rails 11. The clamping structure 21 has guide grooves for engaging with the guide rails 11, ensuring the convenience and reliability of the sliding engagement between the clamping structure 21 and the support beam 10. In this way, by setting the cross-section of the support beam 10 in its length direction to a trapezoidal structure, the support beam 10 itself serves as both a beam and a guide rail. This ensures that the support beam 10 does not occupy a large installation space in the height direction of the receiving slot, while also ensuring that the structure of the support beam 10 is simple enough, thereby reducing the manufacturing difficulty of the limiting components and further ensuring the economy of the server.

[0041] Furthermore, the limiting component 5 provided in this application has a relatively simple structure, and the supporting beam 10 is connected to the top cover 2 of the server, which will not occupy a large space in the server's receiving slot.

[0042] like Figure 4 and Figure 5As shown, the clamping structure 21 includes a slider 211 and a clamping block 212. The slider 211 is slidably engaged with the support beam 10. The clamping block 212 is connected to the slider 211 and extends in a direction away from the support beam 10, with the extension direction perpendicular to the support beam 10. The clamping block 212 has a clamping surface. The two clamping surfaces of the two clamping structures 21 arranged in pairs are arranged opposite each other to effectively clamp the two side surfaces of the tail portion of the graphics processor 4. The surface of the slider 211 away from the clamping block 212 has a guide groove, and the cross-sectional shape of the guide groove in the sliding direction of the slider 211 is adapted to the guide rail 11 to constrain the slider 211 to only slide in engagement with the support beam 10. In this way, by configuring the clamping structure 21 to include a connected slider 211 and a clamping block 212, with the slider 211 slidingly engaged with the support beam 10 and the clamping block 212 connected to the slider 211 and extending in a direction away from the support beam 10 and perpendicular to the support beam 10, it is ensured that the clamping surface of the clamping block 212 can reliably fit against the two rear surfaces of the graphics processor 4, thereby ensuring that the clamping surface of the clamping block 212 has sufficient contact area with the two rear surfaces of the graphics processor 4. This ensures the clamping reliability of the clamping surfaces of the two clamping structures 21 on both sides of the tail of the graphics processor 4. In addition, by setting the clamping block 212 to a structure perpendicular to the support beam 10, it ensures that the surface of the support beam 10 facing the graphics processor 4 can effectively fit against the tail end face of the graphics processor 4 as much as possible. This ensures the reliability of the support beam 10 facing the graphics processor 4 in limiting the graphics processor 4 in the vertical direction of the server, thereby ensuring the effective limiting of the graphics processor 4 by the limiting component 5.

[0043] It should be noted that in this application, the limiting component also includes a fastener 30. The fastener 30 is used to secure the clamping structure 21 when it slides into place, so that the clamping structure 21 can effectively clamp the graphics processor 4. In this way, the fastener 30 effectively limits the clamping structure 21 when it slides into place, thereby ensuring that the fastener 30 will not interfere with the sliding of the clamping structure 21 during the sliding process. Only when the clamping structure 21 slides into place can the fastener 30 be operated by the operator to effectively secure the clamping structure 21, ensuring that the clamping structure 21 can effectively clamp the two sides of the tail of the graphics processor 4. This ensures that the graphics processor 4 will not shake or jump due to poor tail fixation during server operation or transportation, thereby ensuring the stability of server operation and transportation safety.

[0044] Optionally, fastener 30 is a locking screw.

[0045] Furthermore, fastener 30 is disposed on slider 211 to fix clamping structure 21 to support beam 10 after it slides to the target position, thus achieving stable clamping of the graphics processor 4's tail. Technically, fastener 30 is installed using standard threaded connection technology, ensuring reliable fixation between clamping structure 21 and support beam 10. In principle, the tightening process of fastener 30 generates sufficient friction to prevent further sliding of clamping structure 21, while simultaneously applying pressure to the tail of graphics processor 4 through clamping structure 21, thereby fixing graphics processor 4. In terms of effect, this design effectively limits the swaying of the graphics processor 4's tail in any direction, improving the overall stability of the server. In other embodiments, the locking mechanism can employ snap-fit, spring pin, or other types of fasteners to adapt to different operational convenience and safety requirements.

[0046] like Figure 5 As shown, a locking hole is provided on the bottom surface of the guide slide. A fastener 30 passes through the locking hole and is threaded into it. When the clamping structure 21 slides into position, tightening the fastener 30 ensures that the end of the fastener 30 abuts against the surface of the support beam 10 facing the graphics processor 4. Thus, by providing a locking hole on the bottom surface of the guide slide, the fastener 30 passes through the locking hole. During the sliding of the clamping structure 21 on the support beam 10, the end of the fastener 30 does not contact the surface of the support beam 10 facing the graphics processor 4, ensuring the reliability of the clamping structure 21's sliding on the support beam 10. After the clamping structure 21 slides into position, tightening the fastener 30 causes the end of the fastener 30 to pass through the locking hole and abut against the surface of the support beam 10 facing the graphics processor 4, ensuring the reliability of the clamping structure 21's positioning and, consequently, the effectiveness of the clamping structure 21 in clamping the graphics processor 4.

[0047] It should be noted that in this application, the clamping structure 21 and the support beam 10 are detachably connected. This ensures ease of installation and disassembly between the clamping structure 21 and the support beam 10.

[0048] like Figure 5As shown, at least the surface of the support beam 10 facing the graphics processor 4 is flat to effectively fit against the tail end face of the graphics processor 4. This ensures reliable contact between the surface of the support beam 10 facing the graphics processor 4 and the tail end face of the graphics processor 4, thereby ensuring that the surface of the support beam 10 facing the graphics processor 4 can constrain the vertical movement of the graphics processor 4 within the server. Combined with the two clamping structures 21 in the aforementioned clamping group 20, which clamp the tail sides of the graphics processor 4, this ensures reliable limiting of the tail sides of the graphics processor 4 by the two clamping structures 21, constraining the horizontal movement of the graphics processor 4 within the server, and thus ensuring reliable insertion of the head of the graphics processor 4 into the connector slot of the motherboard 3.

[0049] It should be noted that, in the embodiments of this application, reference is made to... Figures 1 to 5 As shown, the two clamping structures 21 in the same clamping group 20 are independently arranged on the support beam 10, and the positions of the two clamping structures 21 on the support beam 10 are adjustable to adjust the clamping distance between the two clamping structures 21; to adapt to graphics processors 4 of different widths; and / or to adapt to the width of at least two adjacent graphics processors 4. This allows the two clamping structures 21 to adapt to graphics processors 4 of different widths by adjusting the clamping distance between them. Furthermore, if multiple graphics processors 4 need to be arranged close together and adjacent to each other, the two clamping structures 21 in the same clamping group 20 can be used to effectively clamp multiple graphics processors 4, saving the number of clamping groups 20 and contributing to the lightweight design of the server.

[0050] Furthermore, the clamping structure 21 is designed to accommodate the tails of graphics processors 4 of varying widths. The sliding block 211 moves along the guide rail of the supporting beam 10 to achieve a secure fit between the tails of graphics processors 4 of different widths. It can also accommodate different numbers of graphics processors 4. Technically, the size design of the clamping structure 21 takes into account the common variations in the width of the graphics processor 4 tails, ensuring its applicability to different models of graphics processors 4. In principle, the cooperation between the sliding block 211 and the guide rail allows the clamping structure 21 to move freely within a certain range, thus adapting to the tails of graphics processors 4 of different widths. In terms of effectiveness, this design allows a single fixing device to serve multiple graphics processor 4 configurations, improving the flexibility and economy of the device. In other embodiments, its applicability can be further expanded by increasing the number of clamping structures 21 or designing a retractable clamping structure 21 mechanism to meet more diverse graphics processor 4 layout requirements.

[0051] It should be noted that, in an embodiment not shown in this application, the limiting component further includes a buffer pad disposed on the clamping surface. This buffer pad prevents scratches on the two sides of the tail of the graphics processor 4, thereby protecting the graphics processor 4 and ensuring its integrity and operational reliability. Furthermore, it also enhances the friction between the clamping surface and the graphics processor 4.

[0052] Optionally, the cushioning pad is attached to the clamping surface, or the cushioning pad is embedded in the clamping surface.

[0053] Optionally, the cushioning pad is a rubber cushioning pad.

[0054] Furthermore, a rubber buffer pad is embedded in the clamping surface of the clamping block 212 of the clamping structure 21. The rubber buffer pad contacts the tail of the graphics processor 4, providing protection and enhancing friction. Technically, the embedding of the rubber buffer pad employs precision molding technology to ensure a perfect fit between the pad and the clamping surface. In principle, the elastic properties of the rubber material can absorb the impact force of the tail of the graphics processor 4 during vibration, while its high coefficient of friction increases the gripping force between the graphics processor 4 and the clamping structure 21. In terms of effect, the use of the rubber buffer pad significantly reduces the relative displacement of the tail of the graphics processor 4 during vibration, reduces the risk of poor contact of the gold fingers, and protects the graphics processor 4 from physical damage. In other embodiments, other types of elastic materials, such as silicone or polyurethane foam, can also be used to adapt to different working environments or improve cost-effectiveness.

[0055] like Figure 4 and Figure 5 As shown, the clamping structure 21 is L-shaped, with two clamping structures 21 arranged back-to-back in pairs, and the clamping surface is flat. By setting the clamping structure 21 in an L-shaped structure, the reliability of the connection between the clamping structure 21 and the supporting beam 10 is ensured, while also ensuring the effectiveness of the clamping structure 21 in clamping the graphics processor 4. Furthermore, the L-shaped clamping structure 21 does not occupy a large installation space in the server's mounting slot, ensuring the overall compactness of the server structure.

[0056] It should be noted that in this application, the support beam 10 is made of aluminum alloy to ensure that it has sufficient strength and lightweight characteristics. Technically, aluminum alloy is chosen based on its good mechanical properties and low weight, making it a common material in server hardware. In principle, the high strength of aluminum alloy means it can withstand large loads without deformation, while its lightweight nature helps reduce the overall weight of the structure, improving the ease of handling the server. In terms of effectiveness, the application of this material allows the support beam 10 to effectively support and guide the clamping structure 21 without adding excessive weight, maintaining the server's high efficiency and portability. In other embodiments, materials such as carbon fiber composites or high-strength steel can also be considered to meet higher strength or corrosion resistance requirements in specific scenarios.

[0057] It should be noted that in this application, the clamping structure 21 is made of engineering plastic, and the material selection between the sliding clamping structure 21 and the supporting beam 10 achieves a balance between lightweight and durability. Technically, engineering plastics are ideal materials for manufacturing the sliding clamping structure 21 due to their good wear resistance, chemical corrosion resistance, and low cost. In principle, the low density of engineering plastics helps reduce the weight of the clamping structure 21 and lower the load on the overall structure, while its durability ensures that the clamping structure 21 is not easily worn or damaged during repeated sliding and fixing processes. In terms of effectiveness, the application of this material allows the clamping structure 21 to perform its function stably for a long time, while reducing maintenance costs. In other embodiments, materials such as metal alloys or high-performance polymers can also be selected to adapt to higher temperature environments or more complex mechanical stress conditions.

[0058] It should be noted that in this application, the physical cooperation between the guide groove of the slider 211 and the guide rail of the supporting beam 10, coupled with the mechanical fixing of the fastener 30 (locking screw), forms a dual mechanism of dynamic adjustment and static locking, ensuring that the tail of the graphics processor 4 is effectively constrained in any state. In terms of effectiveness, the technical solution in this embodiment not only improves the stability of the tail of the graphics processor 4, but also avoids damage that may be caused by direct contact through the rubber buffer pad, while allowing the device to be applied to graphics processors 4 of different widths, greatly enhancing its versatility. In other embodiments, the tail fixing requirements of the graphics processor 4 in different application scenarios can also be solved by changing the shape of the guide rail or using magnetic fixing. For example, in environments requiring frequent disassembly, magnetic fixing can provide a faster installation and disassembly experience.

[0059] It should be noted that in this application, the slider 211 slides laterally along the guide rail of the supporting beam 10 via a guide groove. The fit between the guide groove and the guide rail ensures smooth sliding and positional stability. Technically, the design of the guide groove and guide rail follows the principles of precision manufacturing and tolerance control, ensuring a tight yet flexible fit. In principle, the special shape of the guide rail provides guidance and limiting functions. The movement of the slider 211 is strictly limited by the guide rail, thus ensuring the straightness and stability of the clamping structure 21 during sliding. In terms of effect, this design allows the clamping structure 21 to accurately position itself at the tail of each graphics processor 4, effectively limiting the shaking of the graphics processor 4 and improving the safety of the server during transportation and operation. In other embodiments, the guide rail can be designed in other shapes, such as V-shaped or U-shaped, as long as the same guiding and limiting effects can be achieved.

[0060] It should be noted that in this application, the ease-of-use design of the limiting component 5 enables the clamping structure 21 to move quickly along the guide rail and be fixed with the fastener 30, facilitating rapid installation and subsequent maintenance. Technically, the ease-of-use design encompasses the smoothness of the sliding of the clamping structure 21, the ease of use of the fastener 30, and the rapid installation mechanism of the entire device. In principle, by simplifying the operation process and improving the compatibility between components, users can complete the installation and adjustment of the device without specialized tools. In terms of effectiveness, this design significantly shortens the time required for server assembly and maintenance, reduces operational difficulty, and enhances the user experience. In other embodiments, the ease of operation and the durability of the device can be further improved by introducing an automatic locking mechanism or using more advanced materials, such as shape memory metal materials, which can automatically recover to a preset shape at a specific temperature, thereby achieving automatic positioning and fixing functions.

[0061] The technical solution of this application relates to the usage process. Specifically, during use, the top cover 2 is first placed on the chassis base. At this time, the support beam 10 is pre-fixed to the lower surface of the top cover 2, and the direction of the guide rail is parallel to the arrangement direction of the graphics processors 4. Next, according to the actual position of the tail of the graphics processor 4, the clamping structure 21 is manually slid to the corresponding position of the tail of each graphics processor 4, so that the clamping surface of the clamping structure 21 fits against both sides of the tail of the graphics processor 4. Then, the fasteners 30 on the clamping structure 21 are tightened, and the close contact between the rubber pad and the graphics processor 4 restricts its left-right swaying and up-down jumping, while fixing the position of the clamping structure 21. Finally, the top cover 2 is slidably installed onto the chassis base and the top cover is locked to complete the overall assembly. Throughout the usage process, the structural design of this application ensures all-round constraint of the tail of the graphics processor 4, is easy to operate, has strong versatility, and can quickly adapt to different slots and numbers of graphics processors 4 configurations, effectively improving the safety and reliability of the server during transportation and operation.
