Description

Technical Field

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

[0002] Currently, some chassis in related technologies adopt a rear-out cable layout, while others do not. The rear-out cable layout ensures a neat and aesthetically pleasing front of the rack and facilitates equipment mounting and inspection. The front-out cable layout avoids blocking the cooling airflow at the rear of the rack, thus improving heat dissipation efficiency. However, there are significant differences between front-out and rear-out cable chassis in terms of window structure, internal cavity division, and module design. The same chassis has a single cable exit method, which cannot be flexibly switched and lacks compatibility. Utility Model Content

[0003] This application provides a server chassis to at least solve the problem of limited cabling options in front-out and rear-out chassis in related technologies.

[0004] This application provides a server chassis, including a chassis body, the chassis body having a front window and a rear window, the front window having multiple front cavities, and the rear window having multiple rear cavities; each front cavity is used to selectively install a front panel board structure, a hard disk structure, a hard disk unit, or a front baffle, and the front baffle is installed at the cavity opening of the front cavity when it is in an unoccupied state; each rear cavity is used to selectively install a rear panel board structure or a rear baffle, and the rear baffle is installed at the cavity opening of the rear cavity when it is in an unoccupied state.

[0006] In an exemplary embodiment, the plurality of front cavities include at least two edge cavities and one intermediate cavity. The edge cavities have stop pins on their wall surfaces, and the front plate structure has a first stop groove for engaging with the stop pins to stop the front plate structure in its moving direction. The intermediate cavity has a protruding bent edge on its bottom surface, with both ends of the bent edge extending along a first direction to their respective edge cavities. The front plate structure has a second stop groove for engaging with the bent edge stop to stop the front plate structure in its moving direction. The edge cavities have first connectors on their wall surfaces, and the front plate structure has a second connector for engaging with the first connector to fix the front plate structure within the edge cavities.

[0007] In an exemplary embodiment, in the direction from the front window to the rear window, the first connector is disposed on the window side closer to the front window than the stop pin, and the first connector is threadedly engaged with the second connector.

[0008] In an exemplary embodiment, the front board structure includes a front board bracket, an adapter card, and a first expansion card. The front board bracket has a pair of first stop grooves, a pair of second stop grooves, and a pair of second connectors. The front board bracket also has a first receiving cavity. The adapter card is disposed on the front board bracket. The first expansion card is located in the first receiving cavity.

[0009] In an exemplary embodiment, the top surface of the edge cavity has a first mounting hole, the hard disk structure has a second mounting hole, and the hard disk structure further includes a first fastener that passes through the first mounting hole and the second mounting hole to connect the hard disk structure to the chassis body; the bottom surface of the edge cavity has a third mounting hole, the hard disk structure has a fourth mounting hole, and the hard disk structure further includes a second fastener that passes through the third mounting hole and the fourth mounting hole to connect the hard disk structure to the chassis body; the intermediate cavity has a first guide slide that is only used to provide guidance for the installation of the hard disk body.

[0010] In an exemplary embodiment, the hard disk structure includes a hard disk bracket, a hard disk backplate, and a hard disk tray. The top surface of the hard disk bracket has a second mounting hole, and the bottom surface of the hard disk bracket has a fourth mounting hole. The hard disk backplate is connected to the hard disk bracket and forms a second receiving cavity with the hard disk bracket. The hard disk tray is located in the second receiving cavity to support the hard disk body. A stop edge is provided at the bottom edge of the side where the hard disk bracket is connected to the hard disk backplate. The stop edge abuts against the bent edge to stop the hard disk structure in its moving direction.

[0011] In an exemplary embodiment, the outer peripheral surface of the front baffle has a spring sheet structure, and the front baffle and the cavity opening of the front cavity in an empty state are interference-fitted by the spring sheet structure.

[0014] This application provides a server chassis that achieves diverse front and rear window layouts by configuring the chassis body with multiple front and rear cavities. Each front cavity can selectively install front panel cards, hard drive structures, hard drive units, or front panel baffles, allowing users to flexibly configure the front space of the front window according to different cabling specifications (such as front or rear cabling) and maintenance habits. Similarly, each rear cavity can selectively install rear panel cards or rear baffles, further enhancing the space utilization of the rear window. This design enables the same server chassis to be compatible with multiple configuration schemes, achieving front or rear cabling, or both, without redesigning the chassis body. This significantly improves the versatility of the server chassis and prevents problems such as long development cycles and high mold costs associated with different configurations, greatly reducing the overall production cost of the server chassis.

[0048] 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.

[0049] The embodiments of this application provide a server chassis, and the device is described in detail in conjunction with the structure and working principle of the server chassis (the technical terms involved must be explained).

[0050] like Figures 1 to 22As shown, the server chassis includes a chassis body 10, which has a front window and a rear window. The front window has multiple front cavities 11, and the rear window has multiple rear cavities 12. Each front cavity 11 is used to selectively install a front panel structure 20, a hard disk structure 30, a hard disk body 70, or a front baffle 40. The front baffle 40 is installed at the opening of the front cavity 11 when it is empty. Each rear cavity 12 is used to selectively install a rear panel structure 50 or a rear baffle 60. The rear baffle 60 is installed at the opening of the rear cavity 12 when it is empty.

[0051] This application provides a server chassis that achieves diverse layouts for the front and rear windows by configuring the chassis body 10 with multiple front cavities 11 and multiple rear cavities 12. Each front cavity 11 can selectively install a front panel structure 20, a hard drive structure 30, a hard drive unit 70, or a front baffle 40, allowing users to flexibly configure the front space of the front window according to different cabling specifications (such as front or rear cabling) and maintenance habits. Similarly, each rear cavity 12 can selectively install a rear panel structure 50 or a rear baffle 60, further enhancing the space utilization of the rear window. This design allows the same server chassis to be compatible with multiple configuration schemes, achieving front or rear cabling, or both, without redesigning the chassis body 10. This significantly improves the versatility of the server chassis and prevents problems such as long development cycles and high mold costs associated with different configurations, greatly reducing the overall production cost of the server chassis.

[0052] It should be noted that in this application, multiple front cavities 11 are spaced apart along a first direction, and at least one front cavity 11 is provided with a first guide slide. The first guide slide extends along a second direction perpendicular to the first direction, and the first guide slide is only used to provide guidance for the installation of the hard disk body 70; or, multiple front cavities 11 are spaced apart along the first direction, and at least two front cavities 11 located at the two edges of the chassis body 10 in the first direction are used to selectively install the front panel structure 20, the hard disk structure 30, or the front baffle 40. In this way, the multiple front cavities 11 are spaced apart along the first direction, and by providing a first guide slide in at least one front cavity 11, or by achieving modular installation in the two front cavities 11 located at the two edges of the chassis body 10 in the first direction, the spatial layout of the multiple front cavities 11 is optimized. The first guide rail extends along a second direction perpendicular to the first direction, serving solely as a guide for the installation of the hard drive body 70. This ensures precise positioning and smooth sliding of the hard drive body 70 during insertion into the front cavity 11, preventing damage to the hard drive body 70 due to manual alignment deviations and improving the installation efficiency and reliability of the hard drive body 70. Furthermore, the two front cavities 11 located at the edge are designed to flexibly accommodate the front panel structure 20, the hard drive structure 30, or the front baffle 40. This allows the server chassis to be configured differently based on specific needs for front cabling or storage capacity (such as PCIe expansion or high-density storage). This ensures structural strength in the edge area while providing users with diverse functional expansion options within the front window's internal space, enhancing the server chassis's adaptability to different application scenarios.

[0053] like Figures 1 to 8As shown, the plurality of front cavities 11 include at least two edge cavities 111 and one intermediate cavity 112. The cavity walls of the edge cavities 111 have stop pins 1111, and the front plate structure 20 has a first stop groove 21 for engaging with the stop pins 1111 to stop the front plate structure 20 in its moving direction. The bottom surface of the intermediate cavity 112 has a protruding bent edge 1121, the two ends of which extend along the length direction of the bent edge 1121. Extending in one direction to the corresponding edge cavities 111, the front plate structure 20 has a second stop groove 22 for engaging with the stop of the bent edge 1121, thereby stopping the front plate structure 20 in its moving direction. The cavity wall surface of the edge cavity 111 has a first connector 1112, and the front plate structure 20 has a second connector 26 for engaging with the first connector 1112, thereby fixing the front plate structure 20 in the edge cavity 111. In this way, by setting the stop pin 1111 on the cavity wall surface of the edge cavity 111 and setting the first stop groove 21 on the front plate structure 20 to engage with the stop, the longitudinal positioning of the front plate structure 20 during installation is achieved, effectively preventing the front plate structure 20 from shifting or jamming during the pushing process, and simplifying the installation steps. Meanwhile, the protruding bent edge 1121 on the bottom surface of the intermediate cavity 112 engages with the second stop groove 22 on the front board structure 20 to further restrict the displacement of the front board structure 20 in the moving direction, ensuring the stability of the front board structure 20 inside the chassis and preventing loosening due to vibration or external force. Furthermore, the first connector 1112 on the cavity wall of the edge cavity 111 engages with the second connector 26 on the front board structure 20, providing additional lateral fastening force. This ensures that the front board structure 20 is securely installed within the edge cavity 111, guaranteeing the stability of the electrical connection and the reliability of signal transmission, thus extending the server's lifespan.

[0054] like Figure 2As shown, in the direction from the front window to the rear window, the first connector 1112 is positioned closer to the window side of the front window than the stop pin 1111, and the first connector 1112 is threadedly engaged with the second connector 26. This optimizes the force distribution and ease of disassembly of the front panel structure 20, allowing the fastening force between the first connector 1112 and the second connector 26 to act directly on the front end area of ​​the front panel structure 20, effectively resisting the forward pulling force generated by cable insertion / removal or external vibration, preventing the front panel structure 20 from detaching from the edge cavity 111. Furthermore, the threaded engagement facilitates quick assembly and disassembly by maintenance personnel when replacing or maintaining the front panel structure 20, allowing for fixation or release without special tools through rotation, improving on-site maintenance efficiency and user experience, while also reducing the risk of mechanical damage due to excessive or insufficient tightening.

[0055] In one exemplary embodiment, the first connector 1112 is a fixing nut, and the second connector 26 is a hand screw.

[0056] like Figure 3 and Figure 4 As shown, the front board structure 20 includes a front board bracket 23, an adapter card 24, and a first expansion card 25. The front board bracket 23 has a pair of first stop grooves 21, a pair of second stop grooves 22, and a pair of second connectors 26. The front board bracket 23 also has a first receiving cavity. The adapter card 24 is disposed on the front board bracket 23. The first expansion card 25 is located in the first receiving cavity. In this way, the front board bracket 23, as the main support, integrates a pair of first stop slots 21, a pair of second stop slots 22, and a pair of second connectors 26, ensuring the reliability of the connection between the front board structure 20 and the chassis body 10. The adapter card 24 is set on the front board bracket 23, which allows the front board structure 20 to flexibly adapt to adapter cards 24 of different shapes or interface standards, improving the compatibility of the front board bracket 23. The first expansion card 25 is located in the first receiving cavity of the front board bracket 23, making full use of the internal space of the front board structure 20, providing more expansion interfaces or processing capabilities without increasing the extra volume of the chassis body 10, meeting the needs of expansion performance in high-density computing scenarios. At the same time, the modular design allows faulty components to be replaced individually, reducing the maintenance cost of the server chassis.

[0057] like Figure 2 , Figure 9 , Figure 10As shown, the top surface of the edge cavity 111 has a first mounting hole 1114, the hard disk structure 30 has a second mounting hole 31, and the hard disk structure 30 also includes a first fastener, which passes through the first mounting hole 1114 and the second mounting hole 31 to connect the hard disk structure 30 and the chassis body 10; the bottom surface of the edge cavity 111 has a third mounting hole 1115, the hard disk structure 30 has a fourth mounting hole 32, and the hard disk structure 30 also includes a second fastener, which passes through the third mounting hole 1115 and the fourth mounting hole 32 to connect the hard disk structure 30 and the chassis body 10; the intermediate cavity 112 has a first guide slide, which is only used to provide guidance for the installation of the hard disk body 70. In this way, the first mounting hole 1114 on the top surface of the edge cavity 111 mates with the second mounting hole 31 on the hard disk structure 30, and the third mounting hole 1115 on the bottom surface of the edge cavity 111 mates with the fourth mounting hole 32 on the hard disk structure 30, achieving double fixation of the hard disk structure 30 from top to bottom. This significantly enhances the shock resistance and stability of the hard disk structure 30 within the chassis body 10. The first fastener passes through the first mounting hole 1114 and the second mounting hole 31, and the second fastener passes through the third mounting hole 1115 and the fourth mounting hole 32. This multi-point fixing method effectively disperses the vibration stress of the hard disk structure 30 during operation, reducing the risk of hard disk structure 30 failure or data loss due to vibration, and is particularly suitable for high-density storage scenarios. At the same time, the first guide slide design of the intermediate cavity 112 ensures precise guidance for the installation of the hard disk body 70, allowing the hard disk body 70 to be smoothly and accurately inserted into place, avoiding interface damage caused by hard insertion. This design allows the hard drive body 70 to be directly installed in the first guide slide, while the front cavity 11, which does not have a first guide slide, can selectively install the front panel structure 20, the hard drive structure 30, or the front baffle 40, greatly improving the versatility of the server chassis provided in this application.

[0058] like Figure 2 , Figure 9 and Figure 10As shown, the hard disk structure 30 includes a hard disk bracket 33, a hard disk backplate 34, and a hard disk tray 35. The top surface of the hard disk bracket 33 has a second mounting hole 31, and the bottom surface of the hard disk bracket 33 has a fourth mounting hole 32. The hard disk backplate 34 is connected to the hard disk bracket 33 and forms a second receiving cavity with the hard disk bracket 33. The hard disk tray 35 is located in the second receiving cavity to support the hard disk body 70. A stop edge 36 is provided at the bottom edge of the side where the hard disk bracket 33 is connected to the hard disk backplate 34. The stop edge 36 abuts against the bent edge 1121 to stop the hard disk structure 30 in its moving direction. Thus, the hard drive structure 30 includes a hard drive bracket 33 with a second mounting hole 31 on its top surface and a fourth mounting hole 32 on its bottom surface. Together with the hard drive backplate 34 and the hard drive tray 35, this enables effective installation of the hard drive structure 30. A protruding stop edge 36 at the bottom edge of the side where the hard drive bracket 33 connects to the hard drive backplate 34 abuts against the bent edge 1121 of the intermediate cavity 112, providing longitudinal positioning for the hard drive structure 30. This ensures that the hard drive bracket 33 accurately stops at a predetermined position after being pushed into the edge cavity 111, preventing over-insertion or under-insertion. This ensures correct alignment with the interface of the hard drive backplate 34, precise alignment of the first mounting hole 1114 and the second mounting hole 31, and precise alignment of the third mounting hole 1115 and the fourth mounting hole 32, thereby ensuring reliable connection between the hard drive structure 30 and the chassis body 10. Furthermore, the second receiving cavity formed by the hard drive backplate 34 and the hard drive bracket 33 provides accommodating space for the hard drive body 70, within which the hard drive tray 35 is located to support the hard drive body 70. This structural design not only simplifies the assembly process of the hard drive module, but also improves the connection reliability between the hard drive bracket 33 and the hard drive backplate 34, ensuring the stability of data signal transmission, while facilitating the independent maintenance or replacement of the hard drive tray 35.

[0059] like Figure 11 As shown, the outer periphery of the front baffle 40 has a spring-loaded structure 41, which provides an interference fit between the front baffle 40 and the opening of the unoccupied front cavity 11. This enables tool-free, quick installation between the front baffle 40 and the opening of the unoccupied front cavity 11. The interference fit design of the spring-loaded structure 41 ensures that the front baffle 40 fits tightly against the opening, effectively sealing gaps, preventing dust and foreign objects from entering the chassis, protecting internal electronic components from contamination, and extending the equipment's lifespan. Simultaneously, the friction generated by the interference fit ensures that the front baffle 40 will not detach due to vibration during server chassis operation, maintaining the clean appearance of the server chassis and the airtightness of the air duct. This simple installation method requires no additional screws or tools, reducing installation difficulty and time, improving on-site server chassis assembly efficiency, and also reducing the risk of structural damage due to improper installation.

[0060] like Figure 12 A schematic diagram of the front window structure of a server chassis with rear cabling configuration is given. In the diagram, front baffles are provided at the openings of the front cavity. Figure 13 A schematic diagram of the front window structure of a server chassis with rear cabling configuration is provided. In the diagram, the edge cavity is equipped with a front panel board structure, and the middle cavity is equipped with the hard disk body. Figure 14 A schematic diagram of the front window structure of a server chassis with rear cabling configuration is provided. In the diagram, the edge cavity contains the hard disk structure, and the middle cavity contains the hard disk body. Figure 15 A schematic diagram of the front window structure of a server chassis with rear cabling configuration is provided. In the diagram, one edge cavity has a hard drive structure, another edge cavity has a front baffle, and the middle cavity has the hard drive body.

[0061] Of course, except Figures 12 to 15 Besides the examples given, there are other installation methods, which will not be elaborated here.

[0062] like Figure 16 and Figure 17 As shown, the cavity wall of the rear cavity 12 has a second guide slide, which extends vertically; the rear board structure 50 includes a rear board bracket 51, a second expansion card 52, and a third fastener 53, wherein the side wall of the rear board bracket 51 has a guide groove for cooperating with the second guide slide, and the rear board bracket 51 has a third receiving cavity; the second expansion card 52 is located in the third receiving cavity; the third fastener 53 is used to fix the rear board bracket 51 to the chassis body 10. This ensures that the rear expansion card bracket 51 can slide smoothly along a predetermined trajectory when inserted into the rear cavity 12, avoiding jamming or damage caused by angular deviation, simplifying the installation process. The third receiving cavity inside the rear expansion card bracket 51 is used to accommodate the second expansion card 52, providing sufficient storage space. The setting of the third fastener further fixes the rear expansion card bracket 51 to the chassis body 10, ensuring the installation stability of the rear expansion card structure 50 on the rear window side of the chassis body 10, preventing the rear expansion card structure 50 from loosening due to cable tension or vibration, improving the installation accuracy and operational stability of the rear expansion card structure 50, and meeting the requirements of high-performance servers for the reliability of rear window expansion.

[0063] like Figure 18As shown, the rear baffle 60 has mounting flanges 61 on both sides, and a fifth mounting hole 62 is provided on the mounting flanges 61. The rear board structure 50 also includes a fourth fastener, which passes through the fifth mounting hole 62 and connects to the chassis body 10 to fix the rear baffle 60 at the opening of the rear cavity 12 when it is in an empty state. In this way, the reliability of the rear baffle 60 in the empty rear cavity 12 is achieved. The design of the mounting flanges 61 increases the contact area and stress strength between the rear baffle 60 and the chassis body 10, ensuring the reliability of the installation and fixation of the rear baffle 60, and effectively preventing the rear baffle 60 from shifting or falling off during the operation of the server chassis. The fourth fastener passes through the fifth mounting hole 62 and connects to the chassis body 10, ensuring that the rear baffle 60 can fit tightly against the opening of the cavity, forming an effective sealed space, preventing dust from entering and maintaining the airflow inside the chassis body 10, thus protecting the internal components of the server chassis. This fixing method is simple in structure, easy to operate, and has a stable fixing effect.
