Description

Technical Field

[0001] This application relates to the field of server chassis technology, and in particular to a server chassis structure. Background Technology

[0002] Nowadays, in server chassis design, the chassis cover plays a role in protecting the internal components of the chassis, preventing contaminants, liquids, etc. from entering the chassis, and preventing foreign objects in the external environment (such as particulate matter, corrosive substances, etc.) from damaging electrical components.

[0003] During the installation, inspection, and maintenance of servers, it is often necessary to disassemble and reassemble the server chassis cover. However, the existing chassis uses a threaded connection design, which makes it difficult to remove the cover and cumbersome to assemble (for example, it requires rotating and disassembling multiple connecting screws in sequence). At the same time, it can easily interfere with the installation of external connectors such as cables connected to the chassis, thus making it inconvenient to quickly disassemble and reassemble the server as a whole. Summary of the Invention

[0004] This application provides a server chassis structure to at least solve the problems in the related art where the chassis cover is inconvenient to disassemble and assemble, and easily interferes with the installation of external connectors such as cables connected to the chassis.

[0005] This application provides a server enclosure structure, including: a cover plate and an enclosure; the cover plate is snapped and / or riveted to the enclosure; at least one edge of the cover plate protrudes from the enclosure, the protruding part is a first protruding edge, the first protruding edge has a relief groove, the relief groove passes through the first protruding edge; the end of the enclosure has a connection area, the relief groove is provided corresponding to the connection area, and the width is not less than the width of the connection area.

[0006] This application achieves rapid assembly and disassembly of the cover plate onto the chassis by snapping and / or riveting it to the chassis using a simple structure. Compared to existing industry-standard server chassis top covers that use threaded components (e.g., screw connections), the chassis and cover plate proposed in this application do not require threaded components, thus effectively reducing the production steps for the cover plate and chassis (e.g., reducing the steps of machining threaded holes), improving production efficiency, and simultaneously reducing product costs and enhancing product competitiveness. Furthermore, by providing a clearance groove on the first protruding edge, it facilitates the movement of operators within the connection area. This invention effectively avoids external objects such as tools, hands, and external cables, thereby improving the convenience of subsequent operations such as plugging and unplugging cables and installing equipment on the server chassis structure. By setting up avoidance slots corresponding to the connection area, and ensuring that the width of the avoidance slots is not less than the width of the connection area, the design rationality of the position and size of the avoidance slots and the reliable avoidance of external objects are further guaranteed. This application has a simple structure and low cost, solving the problems of inconvenient disassembly and assembly of the chassis cover in the prior art and easy interference with the installation of external connections such as cables connected to the chassis. It is easy to assemble and maintain, and is suitable for large-scale promotion and use. Attached Figure Description

[0031] 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.

[0032] like Figures 1 to 14 As shown, the embodiments of this application provide a server chassis structure. The device will be described in detail in conjunction with the structure and working principle of the server chassis structure.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the server enclosure structure proposed in this application includes: a cover plate 10 and an enclosure 20; the cover plate 10 is snapped and / or riveted to the enclosure 20; at least one edge of the cover plate 10 protrudes from the enclosure 20, the protruding part is a first protruding edge 11, the first protruding edge 11 has a relief groove 12, the relief groove 12 passes through the first protruding edge 11; the end of the enclosure 20 has a connection area 26, the relief groove 12 is provided corresponding to the connection area 26, and the width is not less than the width of the connection area 26.

[0034] This application achieves quick assembly and disassembly of the cover plate 10 onto the chassis 20 by snapping and / or riveting the cover plate 10 with the chassis 20 using a simple structure. Compared with the existing industry standard server chassis top cover design that uses threaded parts (e.g., screw connections), the chassis 20 and cover plate 10 proposed in this application do not require threaded parts, thereby effectively reducing the production steps of the cover plate 10 and chassis 20 (e.g., reducing the steps of machining threaded holes), improving production efficiency, and also effectively reducing product costs and enhancing product competitiveness. By setting a relief groove 12 on the first protruding edge 11, the connection area is protected. The effective avoidance of external objects such as operating tools, hands, and external cables within the enclosure 26 improves the convenience of subsequent operations such as plugging and unplugging cables and installing equipment on the server chassis structure. By setting the avoidance groove 12 to correspond to the connection area 26, and ensuring that its width is not less than the width of the connection area 26, the rationality of the design of the position and size of the avoidance groove 12 and the reliable avoidance of external objects are further guaranteed. This application has a simple structure and low cost, solving the problems of inconvenient disassembly and assembly of the chassis cover in the prior art and easy interference with the installation of external connectors such as cables connected to the chassis. It is easy to assemble and maintain, and is suitable for large-scale promotion and use.

[0035] It should be noted that the connection area 26 in this application is defined as the space surrounding the server chassis, especially the space at the end of the chassis used for installing, plugging in, or operating external devices and related components. This area mainly includes the space for data cables, expansion cards, and other connectors that require data transmission, power connection, and signal transmission during server operation or maintenance. It also takes into account the space necessary for staff to operate their hands during the above operations. The connection area 26 is designed to ensure that external objects can be plugged in or adjusted without obstruction during normal server operation or maintenance upgrades, thereby improving the server's maintainability and ease of use.

[0036] Specifically, the scope of the connection area 26 within the server enclosure structure proposed in this application takes into account the following aspects: 1. Data cable insertion and removal: Internal electronic devices of the server, such as hard drives, network adapters, expansion cards, etc., need to be connected to external devices or networks via data cables. The connection area 26 must ensure sufficient space for these data cables during insertion and removal operations, avoiding physical interference from the cover plate 10; 2. Expansion card installation: Server expandability is one of its important characteristics. Different application needs can be met by installing or replacing expansion cards (such as PCIe cards; PCIe: Peripheral Component Interconnect Express, a high-speed serial computer expansion bus standard). The connection area 26 must reserve the physical space required for installing expansion cards, as well as the space required for engineers' hand operations when installing or replacing expansion cards; 3. Tool operation: During server maintenance or upgrades, engineers may need to use tools (such as screwdrivers and wrenches) to operate on certain components. The connection area 26 must take into account the space required for these tools, ensuring that the cover plate 10 does not obstruct tool use, thereby simplifying the maintenance process. Therefore, the division of the connection area 26 plays a crucial role in the server chassis structure design. It not only ensures the operability of the server during operation and maintenance, but also improves the utilization efficiency of the server chassis and the user experience. The clearance slot 12 in this application is set corresponding to the connection area 26, and its width is not less than the width of the connection area 26. This design ensures that the cover plate 10 provides the necessary protection while avoiding interference with various external objects in the connection area 26, thus achieving a balance between protection and operational convenience.

[0037] In practical applications, the width and position of the connection area 26 and the clearance slot 12 need to be precisely designed according to the server specifications, internal layout and user operation requirements to ensure the optimization of the server chassis structure, while also reflecting the flexibility and applicability of the design in this application; of course, this design concept is not only applicable to servers, but can also be extended to the chassis structure of other electronic devices that require frequent cable plugging and unplugging and maintenance operations, providing a new solution for improving equipment maintenance efficiency and user experience.

[0038] The design advantage of this application also lies in the fact that the snap-fit ​​fixing of the cover plate 10 to the enclosure 20 simplifies the installation and disassembly process of the cover plate 10, improving the maintenance efficiency of the server enclosure structure. The design of the clearance slot 12 ensures that when operating in the connection area 26, such as plugging and unplugging cables or installing equipment, it will not be obstructed by the cover plate 10, thereby improving the convenience and safety of operation. The application scenarios of the above structure include server assembly, maintenance and upgrades. Especially in high-density server environments, this design can significantly reduce the difficulty of operation for maintenance personnel in a limited space and improve work efficiency.

[0039] In one specific embodiment of this application, such as Figure 7 and Figure 11 As shown, the clearance groove 12 extends through the first protruding edge 11 along the thickness direction of the cover plate 10; and / or, the clearance groove 12 extends into the interior of the cover plate 10.

[0040] In the above embodiment, the clearance groove 12 penetrates the first protruding edge 11 along the thickness direction of the cover plate 10. This means that the clearance groove 12 is a penetrating shape from top to bottom, thereby ensuring that the clearance groove 12 is open along the entire thickness of the cover plate 10, making it easy for external objects (such as operating tools or data cables) to pass through without contacting the cover plate 10. In addition, the clearance groove 12 can also extend into the interior of the cover plate 10, which means that the clearance groove 12 is not only formed on the surface, but extends into the interior of the first protruding edge 11, providing more space for avoiding external objects.

[0041] The above embodiments, by setting the clearance slot 12 as a penetrating or inwardly extending structure, can ensure that when plugging or unplugging cables or performing other operations, the operating tools or cables can easily pass through the clearance slot 12, avoiding any physical interference from the cover plate 10 to these operations; this not only improves the maintainability and ease of use of the server chassis structure, but also reduces the inconvenience of server maintenance and upgrades, making the operation more intuitive and convenient.

[0042] like Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 9 As shown, the box body 20 has corresponding snap-fit ​​grooves 21 on both sides, and the cover plate 10 has snap-fit ​​parts 13 on both sides. The snap-fit ​​part 13 on one side of the cover plate 10 engages with the snap-fit ​​groove 21 on one side of the box body 20, and the snap-fit ​​part 13 on the other side of the cover plate 10 engages with the snap-fit ​​groove 21 on the other side of the box body 20, so that the cover plate 10 and the box body 20 are snap-fitted and fixed.

[0043] The principle of the aforementioned snap-fit ​​design is to utilize the matching of the snap-fit ​​parts 13 on both sides of the cover plate 10 with the snap-fit ​​grooves 21 on both sides of the chassis 20. The installation and removal of the cover plate 10 can be completed through a simple sliding operation, without the need for additional fixing tools or parts, thus simplifying the maintenance process of the server chassis structure. Furthermore, this design enables rapid installation and removal of the cover plate 10, reducing maintenance costs and improving maintenance efficiency. The main application scenarios are in the daily maintenance and upgrades of servers, especially in situations requiring frequent disassembly and reassembly of the cover plate 10, such as on-site server maintenance and troubleshooting.

[0044] like Figure 1 , Figure 3 , Figure 7and Figure 11 As shown, the cover plate 10 includes a plate body 14, a first side body 15, and a second side body 16. The first side body 15 and the second side body 16 are respectively disposed on both sides of the plate body 14 and protrude along the thickness direction of the plate body 14. A snap-fit ​​part 13 is disposed on the side of the first side body 15 facing the second side body 16 and protrudes toward the second side body 16. Another snap-fit ​​part 13 is disposed on the side of the second side body 16 facing the first side body 15 and protrudes toward the first side body 15. When the cover plate 10 is snapped and fixed to the box body 20, the first side body 15 and the second side body 16 are respectively located on the outside of the box body 20.

[0045] The design principle of the above structure is that the snap-fit ​​parts 13 on the first side body 15 and the second side body 16 on both sides of the cover plate 10 cooperate with the snap-fit ​​grooves 21 on both sides of the enclosure 20 to achieve stable fixation of the cover plate 10. The setting of the first side body 15 and the second side body 16 increases the structural strength of the cover plate 10 and prevents deformation or damage during use. The above design improves the installation stability of the cover plate 10 and enhances the protective capability of the server enclosure structure. Application scenarios include high-load and high-vibration server environments, such as data center servers and high-performance computing servers, ensuring the normal operation of the server in harsh environments.

[0046] In addition, the above design also ensures the simplification of the structure of the cover plate 10, which facilitates subsequent stamping and forming and controls costs.

[0047] like Figure 7 and Figure 9 As shown, the snap-fit ​​part 13 includes a first support arm 131, a second support arm 132, and a snap-fit ​​protrusion 133; one end of the first support arm 131 is connected to the cover plate 10, and the other end is connected to one end of the snap-fit ​​protrusion 133, and the first support arm 131 extends into the cover plate 10; one end of the second support arm 132 is connected to the cover plate 10, and the other end is connected to the other end of the snap-fit ​​protrusion 133, and the second support arm 132 extends into the cover plate 10; the snap-fit ​​protrusion 133 is used to snap-fit ​​with the snap-fit ​​groove 21.

[0048] The support provided by the first support arm 131 and the second support arm 132 ensures that the snap-fit ​​protrusion 133 can stably engage with the snap-fit ​​groove 21 during the snap-fit ​​process, thereby achieving rapid fixation of the cover plate 10. This design improves the stability and reliability of the snap-fit ​​process and reduces the possibility of misalignment or damage to the cover plate 10 during snap-fit. The main application scenarios are in the rapid assembly and disassembly of server chassis structures, especially in situations requiring frequent disassembly and assembly of the cover plate 10, such as on-site server maintenance and upgrades.

[0049] In one specific embodiment of this application, a first gap 134 is provided between the cover plate 10 and at least a portion of the two sides of the first support arm 131; and / or, a second gap 135 is provided between the cover plate 10 and at least a portion of the two sides of the second support arm 132; and / or, the cover plate 10 is further provided with a perforated hole 136, which penetrates the cover plate 10 along the thickness direction of the cover plate 10 and corresponds to the snap-fit ​​protrusion 133.

[0050] The structural design in the above embodiments is to provide sufficient space to accommodate the deformation of the snap-fit ​​part 13, thereby ensuring smooth snap-fit ​​between the cover plate 10 and the enclosure 20; the setting of the first gap 134 and the second gap 135, as well as the design of the hollow hole 136, can significantly reduce the probability of the snap-fit ​​part 13 getting stuck during the snap-fit ​​process, ensuring a fast and stable snap-fit ​​between the cover plate 10 and the enclosure 20, thereby improving the maintenance efficiency of the server enclosure structure and the user experience.

[0051] like Figure 4 and Figure 9 As shown, the snap-fit ​​protrusion 133 protrudes along the thickness direction of the cover plate 10, and the protruding part is the snap-fit ​​body 137; when the cover plate 10 is snapped and fixed to the box 20, the snap-fit ​​body 137 is located inside the snap-fit ​​groove 21 and is limited and matched with the inner wall of the snap-fit ​​groove 21 to limit the cover plate 10 along the width direction and / or thickness direction, and the cover plate 10 covers the snap-fit ​​groove 21.

[0052] The tight fit between the snap-fit ​​body 137 and the inner wall of the snap-fit ​​groove 21 restricts the degree of freedom of movement of the cover plate 10 in the width and thickness directions, thereby ensuring the firm fixation of the cover plate 10. The above design improves the fixing strength and stability of the cover plate 10 and enhances the protective capability of the server enclosure structure.

[0053] In addition, it is worth noting that when the cover plate 10 is snapped and fixed to the box body 20, the snap-fit ​​body 137 is located inside the cavity of the snap-fit ​​groove 21 and is limited and matched with the inner wall of the snap-fit ​​groove 21. At this time, the cover plate 10 and the snap-fit ​​body 137 are distributed on both sides of one side wall of the snap-fit ​​groove 21 (that is, the cover plate 10 is located on the outer side of one side outer wall of the snap-fit ​​groove 21, and the snap-fit ​​body 137 is located inside the inner cavity of the outer side wall of the snap-fit ​​groove 21). This arrangement further improves the fit strength between the snap-fit ​​protrusion 133 and the snap-fit ​​groove 21.

[0054] In one specific embodiment of this application, the snap-fit ​​portion 13 is integrally formed with the cover plate 10; and / or, the snap-fit ​​portion 13 is formed by stamping; and / or, the cover plate 10 is formed by stamping.

[0055] In the above embodiments, the snap-fit ​​part 13 and the cover plate 10 can be integrally formed by stamping process; at the same time, the entire cover plate 10 can also be formed by stamping, which means that the snap-fit ​​part 13 and the cover plate 10 can be manufactured as a whole without additional assembly process, simplifying the production process.

[0056] The one-piece molding and stamping design in the above embodiments not only reduces production costs and production processes, but also improves the structural strength between the cover plate 10 and the snap-fit ​​part 13, reducing the risk of structural failure due to improper assembly. The above design is of great significance for improving the production efficiency and product quality of server chassis structures.

[0057] like Figure 4 As shown, the snap-fit ​​groove 21 has a longitudinal extension section 211 and a horizontal extension section 212. The top end of the longitudinal extension section 211 has an inlet, and one end of the horizontal extension section 212 is connected to the bottom end of the longitudinal extension section 211. The snap-fit ​​part 13 enters the longitudinal extension section 211 from the inlet of the corresponding snap-fit ​​groove 21, and then enters the horizontal extension section 212 to snap-fit ​​and fix the cover plate 10 to the box 20.

[0058] The combination of the longitudinal extension section 211 and the horizontal extension section 212 provides space for the snap-fit ​​part 13 to enter and be fixed, while restricting the direction of movement of the cover plate 10 during the installation process, thus ensuring the correct installation of the cover plate 10. At the same time, the above design simplifies the installation process of the cover plate 10 and improves the installation efficiency and accuracy.

[0059] In one specific embodiment of this application, such as Figure 4 As shown, at least one of the following is provided: at the entrance of the longitudinal extension 211 and at the connection between the horizontal extension 212 and the longitudinal extension 211.

[0060] In the above embodiments, at least one of the entrance of the longitudinal extension 211 of the snap-fit ​​groove 21, or the connection between the horizontal extension 212 and the longitudinal extension 211, is rounded. The purpose of this design is to reduce the hard contact and potential wear between the cover plate 10 and the snap-fit ​​groove 21 during the snap-fit ​​process.

[0061] The rounded corner treatment in the above embodiments can significantly reduce the risk of wear and tear on the cover plate 10 and the snap-fit ​​part 13 during installation and disassembly. It also makes the snap-fit ​​process smoother, reduces the difficulty of operation, improves the snap-fit ​​experience between the cover plate 10 and the enclosure 20, and further extends the service life of the server enclosure structure.

[0062] like Figure 3 and Figure 7As shown, there are multiple snap-fit ​​parts 13, which are spaced apart along the extension direction of the cover plate 10; there are multiple snap-fit ​​grooves 21, which are spaced apart along the extension direction of the housing 20, and at least a portion of the multiple snap-fit ​​grooves 21 are arranged in a one-to-one correspondence with the multiple snap-fit ​​parts 13.

[0063] By providing multiple snap-fit ​​parts 13 and snap-fit ​​grooves 21 on the cover plate 10 and the enclosure 20 respectively, the contact points between the cover plate 10 and the enclosure 20 are increased, thereby improving the fixing strength and stability of the cover plate 10; in addition, it also makes the cover plate 10 more firmly fixed to the enclosure 20, enhancing the protective performance, strength and rigidity of the server enclosure structure.

[0064] like Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, the cover plate 10 includes a plate body 14 and an extension 17. The extension 17 is disposed at one end of the plate body 14 and protrudes from the plate body 14. The box body 20 has an opening groove 22. When the cover plate 10 is snapped and fixed to the box body 20, at least a portion of the extension 17 extends into the opening groove 22 and is limited and matched with the inner wall of the opening groove 22 to constrain the cover plate 10.

[0065] The extension 17, in conjunction with the slot 22, further restricts the movement of the cover plate 10 on the enclosure 20, enhancing the fixing and positioning effect of the cover plate 10. This design not only makes the connection between the cover plate 10 and the enclosure 20 more stable and improves the protective performance of the server enclosure structure, but also improves the installation accuracy of the cover plate 10 on the enclosure 20.

[0066] like Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, there are multiple extensions 17, which are spaced apart at one end of the plate 14; there are multiple opening slots 22, and at least a portion of the multiple opening slots 22 are corresponding to the multiple extensions 17.

[0067] By providing multiple extensions 17 at one end of the cover plate 10 and providing multiple corresponding openings and slots 22 on the housing 20, the contact points between the cover plate 10 and the housing 20 are increased, thereby improving the fixing strength and stability of the cover plate 10. In practical use, the cover plate 10 is more firmly fixed to the housing 20, enhancing the overall strength of the server housing structure.

[0068] like Figure 1 and Figure 7As shown, the plate 14 has a thickness direction, a width direction and a length direction that are perpendicular to each other; the cover plate 10 also includes a first side body 15 and a second side body 16, the first side body 15 and the second side body 16 are respectively disposed at both ends of the plate 14 along the width direction, and protrude along the thickness direction of the plate 14 respectively; the extension 17 is disposed at one end of the plate 14 along the length direction, and protrudes along the length direction.

[0069] By providing a first side body 15 and a second side body 16 on both sides of the cover plate 10, and an extension 17 at one end of the plate body 14, the structural strength and stability of the cover plate 10 are increased. At the same time, the structure ensures that the cover plate 10 and the enclosure 20 make contact and fit at multiple angles, thereby improving the fixing effect of the cover plate 10, making the connection between the cover plate 10 and the enclosure 20 more stable, and improving the protective performance of the server enclosure structure.

[0070] like Figure 5 , Figure 6 , Figure 7 and Figure 10 As shown, the cover plate 10 includes a plate body 14, a flange portion 18, and a positioning portion 19. The plate body 14 has a thickness direction, a width direction, and a length direction that are perpendicular to each other. The flange portion 18 is disposed at one end of the plate body 14 along the length direction and protrudes along the thickness direction of the plate body 14. The positioning portion 19 is disposed on the flange portion 18 and protrudes along the length direction. The housing 20 has a positioning groove 23. When the cover plate 10 is snapped and fixed to the housing 20, at least a portion of the positioning portion 19 extends into the positioning groove 23 and is limited and matched with the inner wall of the positioning groove 23 to constrain the cover plate 10.

[0071] The positioning part 19 and the positioning groove 23 work together to ensure the accurate positioning of the cover plate 10 on the enclosure 20, preventing the cover plate 10 from shifting or shaking during use, thereby improving the protective performance and stability of the server enclosure structure; at the same time, it also makes the connection between the cover plate 10 and the enclosure 20 more stable, improving the mechanical performance of the server enclosure structure.

[0072] like Figure 7 and Figure 10 As shown, the flange 18 extends along the width direction; there are multiple positioning parts 19, which are spaced apart on the flange 18 along the width direction of the plate 14; there are multiple positioning grooves 23, at least a portion of which are corresponding to the multiple positioning parts 19.

[0073] By providing multiple positioning parts 19 on the flanged portion 18 and corresponding positioning grooves 23 on the enclosure 20, the contact points between the cover plate 10 and the enclosure 20 are increased, thereby improving the fixing strength and stability of the cover plate 10 and further ensuring the accurate positioning of the cover plate 10 on the enclosure 20. This design allows the cover plate 10 to be more firmly fixed to the enclosure 20, enhancing the protective performance and stability of the server enclosure structure. Practical applications include routine server maintenance and upgrades, especially in situations where ensuring the integrity and protective performance of the server enclosure structure is crucial, such as server transportation and storage.

[0074] like Figure 7 and Figure 10 As shown, the cover plate 10 also includes an extension 17, a first side body 15, and a second side body 16. The first side body 15 and the second side body 16 are respectively disposed at both ends of the plate body 14 along the width direction and protrude along the thickness direction of the plate body 14. The extension 17 is disposed at one end of the plate body 14 along the length direction and protrudes along the length direction. The flange 18 is disposed at the other end of the plate body 14 along the length direction. The protrusion direction of the positioning part 19 is the same as the protrusion direction of the extension 17.

[0075] By providing an extension 17, a first side body 15, a second side body 16, a flange 18, and a positioning part 19 on the cover plate 10, the structural strength and stability of the cover plate 10 are increased, while providing opportunities for multi-angle engagement with the box 20, thereby improving the fixing effect and positional accuracy of the cover plate 10.

[0076] like Figure 1 , Figure 3 and Figure 5 As shown, the enclosure 20 has a protective cavity 24 inside, which is used to house electrical equipment; the enclosure 20 also has a passage 25 communicating with the protective cavity 24, and a cover plate 10 is detachably installed on the enclosure 20 to block at least a portion of the passage 25; wherein, the clearance groove 12 is not communicating with the passage 25.

[0077] By providing a protective cavity 24 inside the enclosure 20, a safe installation space is provided for electrical equipment, preventing interference and damage from the external environment. The design of the access port 25 ensures the maintainability and upgradeability of the electrical equipment, and the detachable design of the cover plate 10 further simplifies the maintenance and disassembly process. The non-connection design between the clearance groove 12 and the access port 25 ensures that the protective effect of the access port 25 will not be affected when operating in the connection area 26, such as plugging or unplugging cables or installing equipment.

[0078] The above design improves the protection and stability of the server enclosure structure, while simplifying the maintenance and disassembly process.

[0079] In one specific embodiment of this application, the cover plate 10 and the box 20 are projected onto the same plane perpendicular to the thickness direction of the cover plate 10, respectively. The projection of the clearance groove 12 and the projection of the through port 25 are spaced apart, and the projection of the cover plate 10 covers at least a portion of the projection of the through port 25.

[0080] In the above embodiment, the projection of the clearance groove 12 and the projection of the passage 25 are spaced apart on the same plane perpendicular to the thickness direction of the cover plate 10, and the projection of the cover plate 10 covers at least a portion of the projection of the passage 25. This means that the clearance groove 12 actually avoids the direct area of ​​the passage 25, but the cover plate 10 can still at least partially cover the passage 25 when installed, thereby providing clearance space while maintaining protection of the passage 25.

[0081] The above embodiment cleverly resolves the conflict between protection and operating space through this projection interval design. Without affecting the normal use of the passageway, the clearance slot 12 ensures that operating tools or cables can move freely within the space where the clearance slot 12 is located. At the same time, the cover plate 10's shielding of the passageway 25 reduces the pollution and damage of the external environment to the internal components of the server, enhancing the overall protection capability of the server.

[0082] In another specific embodiment of this application, the cover plate 10 has a thickness direction, a width direction and a length direction that are perpendicular to each other; the box 20 includes a body, a first support body and a second support body, the first support body is detachably disposed at one end of the body along the width direction, and the second support body is detachably disposed at the other end of the body along the width direction; the snap-fit ​​grooves 21 are respectively disposed on the first support body and the second support body; the snap-fit ​​parts 13 are disposed at both ends of the cover plate 10 along the width direction.

[0083] Based on the above embodiments, the first carrier and the second carrier can be further configured to extend along the length direction and be arranged parallel to each other; there are multiple snap-fit ​​parts 13, which are spaced apart along the length direction; there are multiple snap-fit ​​grooves 21, which are spaced apart along the length direction, and at least a portion of the multiple snap-fit ​​grooves 21 are arranged in a one-to-one correspondence with the multiple snap-fit ​​parts 13.

[0084] The aforementioned snap-fit ​​structure design ensures the cover plate 10 is firmly fixed in the width direction. At the same time, by providing multiple snap-fit ​​grooves 21 on the first and second carriers and multiple snap-fit ​​parts 13 on the cover plate 10, the stability of the cover plate 10 is further improved. This design simplifies the installation and disassembly process of the cover plate 10, while also enhancing the structural strength and stability of the entire server chassis structure.

[0085] In addition, the above design allows the slot 21 to be not directly set on the housing 20. Instead, it can be improved by processing the first and second carriers to improve the existing molded housing. That is, the first and second carriers are processed and installed on the existing housing, so that the existing housing can be used in conjunction with the cover plate 10 proposed in this application.

[0086] like Figure 1 , Figure 3 and Figure 7 As shown, the cover plate 10 has a ventilation hole 191 that penetrates the cover plate 10. The ventilation hole 191 is spaced apart from the clearance groove 12 and communicates with the passage 25.

[0087] By providing ventilation holes 191 on the cover plate 10, a good heat dissipation effect is provided for the server chassis structure, preventing the electrical equipment from overheating. At the same time, the spacing between the ventilation holes 191 and the clearance slot 12 avoids the influence of the ventilation holes 191 on the function of the clearance slot 12. The connection design between the ventilation holes 191 and the through port 25 ensures the heat dissipation effect of the electrical equipment and improves the stability and reliability of the server chassis structure.

[0088] like Figure 7 , Figure 11 and Figure 12 As shown, the ventilation hole 191 is a regular hexagonal hole with a side length not exceeding 4.4 mm; and / or, there are multiple ventilation holes 191, which are arranged in rows and / or columns at intervals.

[0089] By incorporating hexagonal ventilation holes 191, both good heat dissipation and electromagnetic compatibility requirements are ensured, preventing external electromagnetic interference from affecting the normal operation of the server. The row and / or column spacing of multiple ventilation holes 191 further improves the heat dissipation effect, ensuring that the electrical equipment inside the server chassis can operate at a suitable temperature.

[0090] The above design improves the heat dissipation performance and electromagnetic compatibility of the server chassis structure, effectively preventing overheating of electrical equipment and enhancing the stability and reliability of the server chassis structure. Application scenarios include the daily operation of servers, especially in high-load and high-temperature environments, such as data center servers and high-performance computing servers.

[0091] like Figure 7 , Figure 11 and Figure 12As shown, multiple ventilation holes 191 are arranged in rows and columns at intervals to form a first ventilation matrix 192 and a second ventilation matrix 193; the cover plate 10 has a thickness direction, a width direction and a length direction that are perpendicular to each other; the multiple ventilation holes 191 in the first ventilation matrix 192 are arranged in rows along the width direction and in columns along the length direction; the multiple ventilation holes 191 in the second ventilation matrix 193 are arranged in rows along the width direction and in columns along the length direction; wherein, the first ventilation matrix 192 and the second ventilation matrix 193 are spaced apart along the length direction.

[0092] By setting a first ventilation matrix 192 and a second ventilation matrix 193 on the cover plate 10, the heat dissipation holes on the cover plate 10 are evenly distributed, which improves the heat dissipation effect. At the same time, by setting them at intervals, the mutual influence between the two ventilation matrices is avoided, ensuring the heat dissipation effect of each ventilation hole 191.

[0093] It should be noted that in this application, the ventilation holes 191 are designed as regular hexagons and arranged in rows and columns. This design demonstrates significant technical advantages and innovations in the mechanical field, especially in the design of server chassis structures. The following is a detailed explanation: 1. Maximizing space utilization: Compared with circular holes, the regular hexagonal ventilation holes 191 can be arranged more densely on the cover plate 10. This is because hexagonal holes can fill space seamlessly, while circular holes, due to their geometric characteristics, always leave a certain tangential gap. This means that circular holes cannot achieve the highest density on the same area of ​​the cover plate 10. The close arrangement of hexagonal holes means that more ventilation holes 191 can be provided within the limited area of ​​the cover plate 10, thereby increasing the airflow area and improving heat dissipation efficiency. 2. Improved heat dissipation performance: The dense arrangement of ventilation holes 191 makes airflow smoother. Even when the server is running under high load, hot air can be quickly exhausted and cold air absorbed through the hexagonal ventilation holes 191 of the cover plate 10, keeping the internal temperature of the server within a safe range, reducing the failure rate of the server due to overheating, and extending the service life of the server. 3. Cost-effectiveness: Since the high-density arrangement of hexagonal holes can achieve more effective ventilation, it may not be necessary to use larger or more heat dissipation devices in the design of the cover plate 10, thereby reducing material costs and production costs. Furthermore, efficient heat dissipation means that the server's temperature can be better controlled during operation, thereby reducing the energy consumption of the cooling system and lowering overall operating costs; 4. Electromagnetic compatibility: The side length of the regular hexagonal holes is designed not to exceed 4.4mm to meet electromagnetic compatibility requirements. The smaller aperture can effectively shield electromagnetic waves, preventing external electromagnetic interference from affecting the internal signal transmission and data processing of the server, ensuring stable server operation. In contrast, if circular holes larger than 4.4mm are used, the same electromagnetic shielding and heat dissipation effects may not be achieved, while the regular hexagonal ventilation holes 191 provide a better solution in this regard; 5. Structural strength and rigidity: The arrangement of the regular hexagonal holes not only optimizes heat dissipation performance but also considers the structural strength and rigidity of the cover plate 10. Compared with circular holes, the regular hexagonal holes form a more continuous structure in the cover plate 10, which helps to reduce the deformation of the cover plate 10 during long-term use, maintain the flatness and integrity of the cover plate 10, and improve the reliability of the entire server chassis structure; 6. Ease of processing: The stamping process of the regular hexagonal holes is relatively simple, enabling mass production and improving production efficiency. Meanwhile, since the regular hexagonal holes can be arranged closely, the waste of material in the cover plate 10 is reduced, further reducing production costs.

[0094] Therefore, the design of the regular hexagonal ventilation holes 191 in this application, combined with the row and column ventilation matrix design, is based on a comprehensive consideration of factors such as space utilization, heat dissipation performance, cost control, electromagnetic compatibility, and structural strength. This innovative design enables the server chassis structure to meet the requirements of efficient heat dissipation while effectively controlling electromagnetic interference, ensuring the stability and security of the server, and reducing production costs, thus demonstrating the practicality and economic benefits of the design.

[0095] In addition, it is worth noting that in actual use, by setting the distance between the first ventilation matrix 192 and the second ventilation matrix 193 and the internal fan, one of the ventilation matrices can be set as the air intake matrix and the other as the air outlet matrix, thereby making the airflow in the internal protective cavity 24 of the enclosure 20 more reasonable and optimizing the airflow distribution of the internal heat dissipation field.

[0096] In one specific embodiment of this application, the server enclosure structure further includes a cover plate lock 30, which is used to lock and fix the cover plate 10 to the enclosure 20.

[0097] In the above embodiments, the server enclosure structure also includes a cover plate lock 30 for locking the cover plate 10 to the enclosure 20. This means that even if the cover plate 10 and the enclosure 20 are fixed by snap-fit, the cover plate lock 30 can be additionally designed to further ensure the stability of the cover plate 10. The addition of the cover plate lock 30 not only firmly fixes the cover plate 10 to the enclosure 20 to prevent accidental detachment during transportation or operation, but also improves the safety of the server enclosure structure and ensures the safety of the internal components of the server.

[0098] Optionally, the cover plate 10 has mutually perpendicular thickness, width, and length directions; the box body 20 has corresponding insertion slots on both sides along the width direction, the insertion slots are L-shaped slots, the L-shaped slots have a longitudinal mating section and a horizontal mating section, the longitudinal mating section and the horizontal mating section are connected and extend along the length direction respectively; one end of the longitudinal mating section and the horizontal mating section along the length direction has an insertion port, the cover plate 10 enters the longitudinal mating section and the horizontal mating section simultaneously from the corresponding insertion port on both sides along the width direction, the inner wall of the horizontal mating section along the thickness direction and the inner wall of the longitudinal mating section along the width direction together constrain the cover plate 10 so that the cover plate 10 can only slide along the length direction.

[0099] By using the longitudinal and horizontal mating sections of the L-shaped groove to engage with both sides of the cover plate 10, rapid installation and removal of the cover plate 10 on the enclosure 20 are achieved. Simultaneously, the movement of the cover plate 10 in the width and thickness directions is strictly limited, ensuring its stable fixation. This design simplifies the installation and removal process of the cover plate 10, improves the maintenance efficiency of the server enclosure structure, and ensures the stable fixation of the cover plate 10.

[0100] like Figure 1 , Figure 3 , Figure 5 , Figure 13 and Figure 14 As shown, the server chassis structure also includes an electrical bracket for installing electrical equipment. The electrical bracket has a clearance groove 41 on its edge for avoiding objects located outside the electrical bracket.

[0101] By incorporating clearance slots 41 along the edges of the electrical brackets, additional space is provided for the installation and maintenance of electrical equipment. This prevents the electrical brackets from interfering with external objects such as tools or hands during installation and maintenance, improving operational convenience and safety. This design simplifies the installation and maintenance process of electrical equipment and enhances the maintenance efficiency and safety of the server enclosure structure. Application scenarios include server assembly, maintenance, and upgrades, particularly in situations requiring the installation or maintenance of electrical equipment on the electrical brackets, such as on-site server maintenance and troubleshooting.

[0102] like Figure 5 , Figure 13 and Figure 14 As shown, the electrical bracket includes an expansion bracket 40 for mounting an expansion card 50, and the edge of the expansion bracket 40 has a recessed groove 41.

[0103] By providing a clearance slot 41 along the edge of the expansion bracket 40, additional space is provided for the installation and maintenance of the expansion card 50. This avoids interference from the expansion bracket 40 with tools, data cables, and hands during installation and maintenance, improving operational convenience and safety. This design simplifies the installation and maintenance process of the expansion card 50 and improves the maintenance efficiency and safety of the server chassis structure. Application scenarios include server assembly, maintenance, and upgrades, especially in situations where the expansion card 50 needs to be installed or maintained on the expansion bracket 40, such as on-site server maintenance and troubleshooting, and particularly when it is necessary to install and upgrade the expansion card 50 to increase server functionality or performance.

[0104] In one specific embodiment of this application, the clearance groove 41 penetrates the edge of the expansion bracket 40 and extends into the interior of the expansion bracket 40.

[0105] The design of the clearance slot 41 in the above embodiment ensures that when plugging or unplugging the data cable 60 or installing the expansion card 50, the operator's hand or tools can pass through the clearance slot 41 without obstruction and directly operate the expansion card 50, which greatly improves the convenience and efficiency of operation. At the same time, it also avoids damage to the expansion bracket 40 and extends the service life of the server chassis structure.

[0106] It is worth noting that in one specific embodiment of this application, the server further includes an expansion card 50 and a data cable 60, and the electrical bracket includes an expansion bracket 40 with a recessed groove 41 on its edge; wherein, the expansion card 50 is mounted on the expansion bracket 40, and one end of the data cable 60 is inserted into the expansion card 50 to connect with the expansion card 50; the extending direction of the recessed groove 41 is parallel to the movement direction of the data cable 60 when it is inserted into the expansion card 50.

[0107] By designing the extension direction of the recess 41 in the above embodiment to be parallel to the movement direction of the data cable 60 when it is inserted into the expansion card 50, an effective recess space is provided, making the operation of the data cable 60 and the expansion card 50 more convenient. This embodiment ensures that the data cable 60 and the expansion card 50 are not obstructed by any physical obstacles during operation, allowing operators to more easily plug and unplug cables or install expansion cards, improving the usability and maintenance efficiency of electrical equipment, while also reducing the risk of damage that may occur during operation, and improving the overall performance and reliability of electrical equipment. The design of the above embodiment enhances the scalability of the server while optimizing the operation process, greatly improving the user experience when using and maintaining the server.

[0108] The specific structure and design principles of one embodiment of this application will now be described in detail as follows:

[0109] Figure 1 The diagram shows the overall appearance of the server chassis structure. It can be seen that the server chassis structure consists of a chassis 20 and a cover plate 10. The chassis 20 has an internal protective cavity 24 for housing electrical equipment, and a passageway 25 communicating with the protective cavity 24. The cover plate 10 is designed to be detachably mounted on the chassis 20 to cover the passageway 25, protecting the electrical equipment from external factors. Notably, the cover plate 10 has a first protruding edge 11 along its edge, and a clearance groove 12 is formed on the first protruding edge 11. This clearance groove 12 penetrates the first protruding edge 11 and corresponds to the connection area 26 of the chassis 20, preventing interference with external objects such as cables of the electrical equipment within the connection area 26 and ensuring ease of operation.

[0110] Figure 1 , Figure 3 , Figure 5 and Figure 7By combining the components, the snap-fit ​​fixing process between the cover plate 10 and the housing 20 can be derived. In the figure, the housing 20 has snap-fit ​​grooves 21 on both sides. Each snap-fit ​​groove 21 is L-shaped and consists of a longitudinal extension section 211 and a horizontal extension section 212. The top of the longitudinal extension section 211 has an inlet, and one end of the horizontal extension section 212 connects to the bottom end of the longitudinal extension section 211. The cover plate 10 has snap-fit ​​parts 13 on both sides. Each snap-fit ​​part 13 includes a first support arm 131, a second support arm 132, and a snap-fit ​​protrusion 133. One end of the first support arm 131 and the second support arm 132 is connected to the cover plate 10, and the other end is connected to the snap-fit ​​protrusion 133. The snap-fit ​​protrusion 133 is used to limit the engagement with the inner wall of the snap-fit ​​groove 21, thereby achieving the snap-fit ​​fixing of the cover plate 10 and the housing 20. The snap-fit ​​protrusion 133 protrudes along the thickness direction of the cover plate 10 to form a snap-fit ​​body 137. When the cover plate 10 is installed on the housing 20, the snap-fit ​​body 137 is located inside the snap-fit ​​groove 21 and is matched with the inner wall of the snap-fit ​​groove 21 to limit the width and thickness of the cover plate 10, thereby ensuring the stability of the installation and the accuracy of the positioning.

[0111] Figures 7 to 12 The structural details of the cover plate 10 are shown. The cover plate 10 consists of a plate body 14, a first side body 15, and a second side body 16. The first side body 15 and the second side body 16 are respectively located at both ends of the plate body 14 along the width direction and protrude along the thickness direction of the plate body 14. An extension 17 is located at one end of the plate body 14 along the length direction and protrudes along the length direction. It is used to extend into the opening slot 22 of the housing 20 to further constrain the cover plate 10 and ensure its stable installation on the housing 20. In addition, a ventilation hole 191 penetrates the cover plate 10, is spaced apart from the clearance slot 12, and communicates with the passage 25. The ventilation hole 191 is a regular hexagonal hole with a side length of no more than 4.4 mm, which effectively prevents electromagnetic interference and improves the heat dissipation efficiency of the system. There are multiple ventilation holes 191, which are arranged in rows and / or columns at intervals to form a first ventilation matrix 192 and a second ventilation matrix 193. The two matrices are arranged at intervals along the length direction, which not only ensures good heat dissipation performance, but also meets the requirements of electromagnetic compatibility.

[0112] Figure 4 , Figure 7 and Figure 9 The sliding constraint design of the cover plate 10 and the housing 20 can be combined to demonstrate this. The electrical bracket is used to install electrical equipment and has a clearance groove 41 on its edge. The clearance groove 41 is used to avoid objects located outside the electrical bracket, such as cables, heat sinks, etc., ensuring that the normal operation of the electrical equipment is not obstructed. In some embodiments, such as... Figure 13 and Figure 14As shown, the electrical support can be further divided into a basic support and an expansion support 40. The expansion support 40 is used to install devices such as expansion cards 50. Its edge is also provided with a clearance groove 41 to adapt to the installation requirements of different devices, thereby enhancing system compatibility and flexibility.

[0113] Figure 7 and Figure 10 The positioning design of the cover plate 10 is shown. The cover plate 10 includes a plate body 14, a flange portion 18, and a positioning portion 19. The plate body 14 has mutually perpendicular thickness, width, and length directions. The flange portion 18 is provided at one end of the plate body 14 along the length direction and protrudes along the thickness direction of the plate body 14. The positioning portion 19 is provided on the flange portion 18 and protrudes along the length direction. Figure 5 and Figure 6 As shown, the housing 20 has a positioning groove 23. At least a portion of the positioning part 19 extends into the positioning groove 23 and engages with the inner wall of the positioning groove 23 to further constrain the cover plate 10 and ensure its accurate positioning on the housing 20. Multiple positioning parts 19 are spaced apart on the flange 18 along the width direction of the plate 14. Similarly, multiple positioning grooves 23 are also present, with at least a portion of each groove corresponding to one of the positioning parts 19. This multi-point positioning design effectively improves the stability and reliability of the cover plate 10 on the housing 20.

[0114] Figure 7 The cover plate 10 includes an extension 17, a first side body 15, and a second side body 16. The extension 17 is located at one end of the plate 14 along the length direction and protrudes along the length direction to extend into the opening slot 22 of the box 20 to constrain the cover plate 10. The flange 18 is located at the other end along the length direction, and the protruding direction of the positioning part 19 is the same as the protruding direction of the extension 17. This design ensures the full constraint and positioning of the cover plate 10 on the box 20, improving the stability of the structure and the convenience of operation.

[0115] Through the technical solutions of the above embodiments, the server chassis structure of this application not only simplifies the disassembly and assembly process and improves maintenance efficiency, but also improves the installation method of the cover plate 10 through the avoidance groove 12 and the snap-fit ​​fixing design, reducing production steps, improving production efficiency, reducing product costs, and enhancing product competitiveness; at the same time, the avoidance groove design of the electrical bracket and the expansion bracket 40 ensures the normal operation of electrical equipment and improves system compatibility; in addition, the matrix design of the ventilation holes 191 not only ensures good heat dissipation performance, but also meets electromagnetic compatibility requirements, realizing comprehensive optimization of the server chassis structure in terms of heat dissipation, electromagnetic shielding, etc., improving the ease of use and maintainability of the server chassis structure, reducing maintenance costs, and making it suitable for large-scale promotion and use.

[0116] The server chassis structure proposed in this application allows for tool-free manual operation and maintenance, and its structure is applicable to server chassis of various sizes; the cover plate 10 features an integral threadless design. Compared with the industry's conventional server chassis cover design using threaded components (e.g., designs with screws on both sides of the chassis cover for fixing), the integral threadless design of the cover plate 10 in this application reduces production steps, improves production efficiency, and lowers product costs, thereby enhancing product competitiveness.

[0117] By designing a cover plate lock 30 on the cover plate 10, the cover plate 10 can be operated and locked without tools. The cover plate lock 30 is fixed in conjunction with the positioning pin on the housing 20 to complete the fixed locking of the cover plate 10. In actual use, the cover plate lock 30 can be placed in the middle area of ​​the cover plate 10 to further facilitate the installation and removal of the cover plate 10 by the staff.

[0118] The cover plate 10 is designed with regular hexagonal ventilation holes 191 to maximize the system's heat dissipation and ventilation volume and reduce the system's power consumption and temperature. The first ventilation matrix 192 located at the front end of the cover plate 10 along the length direction includes three rows of ventilation holes 191 to increase the system's air intake. The second ventilation matrix 193 located at the rear end of the cover plate 10 along the length direction includes four rows of ventilation holes 191 to increase the system's air output. The ventilation holes 191 on the cover plate 10 not only improve the system's heat dissipation function but also meet the product's electromagnetic compatibility requirements. The ventilation holes 191 can be designed as regular hexagons with a side length of 4.4mm.

[0119] The expansion bracket 40 (e.g., a PCIe card bracket; PCIe: Peripheral Component Interconnect Express, a high-speed serial computer expansion bus standard) has a clearance slot 41 to avoid data cable plugging and unplugging operations. This provides space for cable plugging and unplugging in the server cable plugging and unplugging area, enabling direct manual cable plugging and unplugging, thus improving product usability and maintainability. Server brackets in the industry typically lack this clearance slot 41, therefore tools are usually required to plug and unplug data cables at the rear and top of the product. The clearance slot 41 on the expansion bracket 40 significantly improves the ease of use and convenience of cable plugging and unplugging in server products, surpassing conventional server products in the industry.

[0120] In summary, this application provides a server chassis structure. By using a cover plate 10 and a chassis 20 for snap-fit ​​and / or riveting fixation, this application achieves quick assembly and disassembly of the cover plate 10 onto the chassis 20 with a simple structure. Compared to existing industry-standard server chassis top covers that use threaded components (e.g., screw connections), the chassis 20 and cover plate 10 proposed in this application do not require threaded components, thus effectively reducing the production steps for the cover plate 10 and chassis 20 (e.g., reducing the steps for machining threaded holes), improving production efficiency, and simultaneously reducing product costs and enhancing product competitiveness. Furthermore, the first protruding edge 11 has a clearance groove. 12. This design effectively avoids external objects such as tools, hands, and external cables within the connection area 26, thereby improving the convenience of subsequent operations such as plugging and unplugging cables and installing equipment on the server chassis structure. By setting the avoidance groove 12 corresponding to the connection area 26, and ensuring that its width is not less than the width of the connection area 26, the design rationality of the position and size of the avoidance groove 12 and the reliable avoidance of external objects are further guaranteed. This application has a simple structure and low cost, solving the problems of inconvenient disassembly and assembly of the chassis cover in the prior art and easy interference with the installation of external connectors such as cables connected to the chassis. It is easy to assemble and maintain, and is suitable for large-scale promotion and use.

[0121] The server chassis structure and server provided in this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
