[0053] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0055] To address the issue that the connection method between the motherboard tray and the chassis base in related technologies cannot ensure ease of assembly, this application provides a server chassis module.

[0056] As shown in Figures 1 to 21, the server chassis module includes a chassis base 10 and a motherboard tray 20. The chassis base 10 has a support groove 11, and a convex bridge structure 12 is provided on the bottom surface of the support groove 11. A through hole structure 21 is provided at the position opposite to the convex bridge structure 12 on the motherboard tray 20. The convex bridge structure 12 and the through hole structure 21 cooperate to connect the motherboard tray 20 and the chassis base 10.

[0057] Applying the technical solution of this application, a server chassis module is provided, including a chassis base 10 and a motherboard tray 20. The chassis base 10 has a support groove 11, and a convex bridge structure 12 is provided on the bottom surface of the groove 11. A through-hole structure 21 is provided on the motherboard tray 20 at a position opposite to the convex bridge structure 12. The convex bridge structure 12 and the through-hole structure 21 cooperate to connect the motherboard tray 20 and the chassis base 10. In this way, the motherboard tray 20 is positioned and installed on the chassis base 10 through the cooperation of the convex bridge structure 12 and the through-hole structure 21. Compared with the existing I-beam and loop hole methods, the contact area between the convex bridge structure 12 and the through-hole structure 21 is larger, improving the assembly efficiency between the motherboard tray 20 and the chassis base 10. Furthermore, the motherboard tray 20 and the chassis base 10 are easier to disassemble, greatly improving the ease of assembly and disassembly between the motherboard tray 20 and the chassis base 10.

[0058] As shown in Figures 1, 2, 9, and 10, in the direction from the front window to the rear window of the server chassis module, the bridge structure 12 sequentially includes a first bridge segment 121, a second bridge segment 122, and a third bridge segment 123 connected to each other. The first bridge segment 121 extends upward at an angle, the second bridge segment 122 extends horizontally, and the third bridge segment 123 extends downward at an angle. At least a portion of the width of the second bridge segment 122 is greater than the width of the first bridge segment 121, and at least a portion of the width of the second bridge segment 122 is greater than the width of the third bridge segment 123. In the direction from the front window to the rear window of the server chassis module, the via structure 2... 1 includes, in sequence, a first sub-limiting hole segment 211, a second sub-limiting hole segment 212, and a third sub-limiting hole segment 213 that are connected to each other. The width of the first sub-limiting hole segment 211 is greater than the width of the third sub-limiting hole segment 213. The second sub-limiting hole segment 212 is conical. The large end of the second sub-limiting hole segment 212 is connected to the first sub-limiting hole segment 211, and the small end of the second sub-limiting hole segment 212 is connected to the third sub-limiting hole segment 213. At least a portion of the width of the second convex bridge segment 122 is less than the width of the first sub-limiting hole segment 211, and at least a portion of the width of the second convex bridge segment 122 is greater than the width of the third sub-limiting hole segment 213. In this way, by setting the convex bridge structure 12 to include a first convex bridge segment 121, a second convex bridge segment 122, and a third convex bridge segment 123 connected in sequence, and setting the through hole structure 21 to include a first sub-limiting hole segment 211, a second sub-limiting hole segment 212, and a third sub-limiting hole segment 213 connected in sequence, the assembly convenience of the convex bridge structure 12 and the through hole structure 21 is ensured, which facilitates the quick installation of the motherboard tray 20 onto the chassis base 10, thereby improving the assembly efficiency of the motherboard tray 20 and the chassis base 10. During assembly, the second convex bridge segment 122 of the convex bridge structure 12 needs to pass through the first sub-limiting hole segment 211, and then slide the motherboard tray 20 along a preset direction so that the second convex bridge segment 122 abuts against and overlaps the second sub-limiting hole segment 212 and the third sub-limiting hole segment 213.

[0059] It should be noted that in this application, the convex bridge structure 12 is stamped, which helps to reduce the processing and manufacturing cost of the server chassis module. Compared with the existing I-beam and gourd hole combination, the contact area between the convex bridge structure 12 and the through hole structure 21 is larger, which improves the assembly efficiency between the motherboard tray 20 and the chassis base 10. In addition, the motherboard tray 20 and the chassis base 10 are also easier to disassemble, which greatly improves the ease of disassembly and assembly between the motherboard tray 20 and the chassis base 10.

[0060] As shown in Figures 6, 7, and 9, the bottom surface of the support groove 11 is further provided with a first convex structure 111, which has a first mounting hole 1111. The motherboard tray 20 is provided with a second convex structure 24, which has a second mounting hole 241. The server chassis module also includes a first fastener, which passes through the second mounting hole 241 and the first mounting hole 1111 in sequence to connect the motherboard tray 20 and the chassis base 10. In this way, the reliable connection between the motherboard tray 20 and the chassis base 10 is achieved through the cooperation of the first fastener and the first mounting hole 1111.

[0061] In some embodiments of this application, the first fastener has an external thread structure and the first mounting hole 1111 has an internal thread structure, so that the first fastener and the first mounting hole 1111 are threadedly connected.

[0062] In some embodiments of this application, the first convex hull structure 111 is a convex hull with a bud. This helps to reduce the use of press-fit studs, I-beams, and riveting processes, resulting in a higher cost-performance ratio.

[0063] As shown in Figures 1, 3, 6, 7, and 9, a first limiting protrusion 112 protrudes from the wall of the bearing groove 11, and the side of the first limiting protrusion 112 facing the bottom of the bearing groove 11 has a first stop surface; a limiting flange 25 protrudes from the outer periphery of the motherboard tray 20. After the motherboard tray 20 is installed on the chassis base 10, the first stop surface and the limiting flange 25 engage to restrain the motherboard tray 20 from moving away from the bottom of the bearing groove 11. In this way, the engagement of the first limiting protrusion 112 and the limiting flange 25 prevents the motherboard tray 20 from moving away from the bottom of the bearing groove 11, thereby restraining the movement of the motherboard tray 20 from the bottom to the opening of the bearing groove 11.

[0064] As shown in Figures 3 and 9, the first stop surface is a plane; and / or, there are multiple first limiting protrusions 112, at least two of which are located at two opposite groove walls of the bearing groove 11; there are multiple limiting flanges 25, at least two of which are located at two opposite side edges of the motherboard tray 20; and the multiple limiting flanges 25 correspond one-to-one with the multiple first limiting protrusions 112; and / or, in the direction from the front window to the rear window of the server chassis module, the extension length of the first limiting protrusion 112 is less than the extension length of the limiting flange 25. Thus, the first stop surface is a plane, which helps to increase the stop engagement area between the first stop surface and the limiting flange 25; the setting of multiple first limiting protrusions 112 and multiple limiting flanges 25, and the fact that at least two of the multiple first limiting protrusions 112 are respectively located at two opposite groove walls of the bearing groove 11, ensures that the motherboard tray 20 and the chassis base 10 have multiple stop points, while ensuring the constraint on the movement of the motherboard tray 20 in the direction from the bottom to the opening of the bearing groove 11; the extension length of the first limiting protrusion 112 is less than the extension length of the limiting flange 25. Since the motherboard tray 20 needs to be slidably installed on the chassis base 10, it prevents the movement of the motherboard tray 20 from causing the first limiting protrusion 112 and the limiting flange 25 to fail to effectively stop and engage.

[0065] As shown in Figure 14, the wall of the support groove 11 is provided with cable management protrusions 13. There are at least two cable management protrusions 13, and the distance between the at least two cable management protrusions 13 and the bottom surface of the support groove 11 is equal. The at least two cable management protrusions 13 are spaced apart in the direction from the front window to the rear window of the server chassis module. The server chassis module also includes a motherboard body 30 and a memory module 40. The motherboard body 30 is mounted on the motherboard tray 20. The memory module 40 is mounted on the motherboard body 30 and extends along the direction from the front window to the rear window of the server chassis module. The memory module 40 has a memory partition 41, and a cable management channel 100 is formed between the memory partition 41 and the at least two cable management protrusions 13. This ensures the reliability of the cable constraint, thereby ensuring a relatively neat overall layout, eliminating the need for additional cable management structures, reducing space occupation, and minimizing the development of new molds, which helps to reduce the manufacturing cost of the server chassis module.

[0066] As shown in Figures 1, 6, 8, and 17, a first limiting protrusion 112 protrudes from the wall of the support groove 11, and the first limiting protrusion 112 has a first stop surface on the side facing the bottom of the support groove 11; a limiting flange 25 protrudes from the outer periphery of the motherboard tray 20. After the motherboard tray 20 is installed on the chassis base 10, the first stop surface and the limiting flange 25 stop and cooperate to constrain the motherboard tray 20 to move away from the bottom of the support groove 11; a second limiting protrusion 113 protrudes from the wall of the support groove 11, and the second limiting protrusion 113 has a second stop surface on the side facing the rear window of the server chassis module; a stop structure 26 is provided on the outer periphery of the motherboard tray 20, and the stop structure 26 is positioned in the direction from the front window to the rear window of the server chassis module. The system includes a first stop flange 261, a groove structure 262, and a second stop flange 263 connected to each other. After the motherboard tray 20 is installed onto the chassis base 10, the second limiting protrusion 113 is located at the groove structure 262, and the second stop surface cooperates with the groove wall surface of the groove structure 262 to constrain the motherboard tray 20 to move towards the rear window side of the server chassis module. Each cable management protrusion 13 is located between the first limiting protrusion 112 and the second limiting protrusion 113, and the first distance H1 between each cable management protrusion 13 and the bottom surface of the support groove 11, the second distance H2 between the first limiting protrusion 112 and the bottom surface of the support groove 11, and the third distance H3 between the second limiting protrusion 113 and the bottom surface of the support groove 11 satisfy the following: H1 > H2 and H1 > H3. This ensures that the memory module 40 is installed in the space between the first limiting protrusion 112 and the second limiting protrusion 113 on the motherboard body 30, so that the space of the cable management channel 100 formed between the memory partition 41 and at least two cable management protrusions 13 is sufficient for cable management.

[0067] As shown in Figures 1, 6, 9, and 11, a first support protrusion 14 is provided on the bottom surface of the support groove 11. A first clearance through hole 27 is provided on the motherboard tray 20 at the position opposite to the first support protrusion 14 to avoid the first support protrusion 14. The server chassis module also includes a motherboard body 30, which is mounted on the motherboard tray 20. A CPU module 50 is also mounted on the motherboard tray 20. The first support protrusion 14 is used to provide support for the CPU module 50. In this way, the reliability of the support for the CPU module 50 is ensured. The chassis base 10 is relatively thick and has strong support force, which helps to reduce the risk of stress and strain deformation of the motherboard body 30 and ensures the reliability of the server chassis module.

[0068] As shown in Figures 1 and 5, the server chassis module also includes a chassis cover, which covers the opening of the support groove 11 and forms a receiving cavity with the support groove 11. A shielding protrusion 15 protrudes from the side wall of the chassis base 10, and the shielding protrusion 15 contacts the inner wall of the chassis cover to conduct electricity between the chassis base 10 and the chassis cover. This connection between the chassis base 10 and the chassis cover helps to achieve electromagnetic shielding.

[0069] As shown in Figures 9 to 11, the motherboard tray 20 is provided with a third convex structure 28, which has a third mounting hole 281. The server chassis module also includes a motherboard body 30 and a second fastener. A fourth mounting hole is provided at a position opposite to the third convex structure 28 on the motherboard body 30. The second fastener passes through the fourth mounting hole and the third mounting hole 281 in sequence to connect the motherboard body 30 and the motherboard tray 20. Thus, the cooperation between the second fastener and the third mounting hole 281 connects the motherboard body 30 and the motherboard tray 20, thereby ensuring the reliability of the connection between the motherboard body 30 and the motherboard tray 20.

[0070] In some embodiments of this application, the second fastener has an external thread structure and the third mounting hole 281 has an internal thread structure, so that the second fastener is threadedly connected to the third mounting hole 281.

[0071] In some embodiments of this application, the third convex hull structure 28 is a convex hull with a bud. This helps to reduce the use of press-fit studs, I-beams, and riveting processes, resulting in a higher cost-effectiveness.

[0072] As shown in Figure 9, the motherboard tray 20 has multiple second support protrusions 29, which are spaced apart along the length and width of the motherboard tray 20 to provide support for the motherboard body 30. In this way, the multiple second support protrusions 29 provide support for the motherboard body 30.

[0073] As shown in Figures 1, 4, 11, and 12, the motherboard tray 20 is further provided with at least two protruding positioning posts 210, and the motherboard body 30 has at least two sliding positioning holes 31. The number of sliding positioning holes 31 is the same as the number of positioning posts 210, and they correspond one-to-one. The motherboard body 30 is positioned and mounted on the motherboard tray 20 through the cooperation of the sliding positioning holes 31 and the positioning posts 210. In this way, the setting of at least two positioning posts 210 ensures the reliable positioning of the motherboard body 30.

[0074] It should be noted that in this application, the height of the positioning post 210 is greater than the height of the second support protrusion 29. This allows the positioning post 210 to provide coarse positioning for the motherboard body 30.

[0075] As shown in Figures 11, 13, and 18 to 20, the server chassis module also includes a support bracket 60, which is mounted on the motherboard body 30. The support bracket 60 has a support area on the side facing the front window of the server chassis module, which is used to support the server module 70. A first positioning stud 32 protrudes from the motherboard body 30 and has a first internal thread structure. The support bracket 60 has a first mounting lug 61 on the side facing the rear window of the server chassis module. The first mounting lug 61 extends horizontally and has a second clearance hole. The server chassis module also includes a hand screw 80, which has a first external thread structure and passes through the second clearance hole and is threadedly engaged with the first internal thread structure. This ensures the reliability of the first positioning stud 32 in supporting and limiting the support bracket 60, the stability and ease of installation of the support bracket 60, and the reliability of the support bracket 60 in supporting the server module 70, making full use of the limited space on the motherboard body 30.

[0076] In some embodiments of this application, the server module 70 is an M.2 module, and the support bracket 60 is a bracket structure for supporting the M.2 module.

[0077] As shown in Figures 18, 20, and 21, the support bracket 60 has a second mounting lug 62 on the side facing the front window of the server chassis module. The second mounting lug 62 extends horizontally and has a third clearance hole. The motherboard tray 20 has a fourth convex structure 220, which has a fifth mounting hole 2201, and the wall of the fifth mounting hole 2201 has a second internal thread structure. The motherboard body 30 has a sixth mounting hole at a position opposite to the fifth mounting hole 2201. The server chassis module also includes a second positioning stud 90. The second positioning stud 90 includes, in the direction from the bottom to the opening of the bearing groove 11, the second positioning stud 90 sequentially includes... The first shaft segment 91, the second shaft segment 92, and the third shaft segment 93 are connected. At least a portion of the first shaft segment 91 has a second external thread structure for mates with a second internal thread structure. The diameter of the second shaft segment 92 is larger than the diameter of the first shaft segment 91, forming a first stop ring surface at their connection. The first shaft segment 91 passes through a sixth mounting hole and extends into a fifth mounting hole 2201, so that the first stop ring surface abuts against the motherboard body 30. The diameter of the second shaft segment 92 is larger than the diameter of the third shaft segment 93, forming a second stop ring surface at their connection. The third shaft segment 93 passes through a third clearance hole, so that the second stop ring surface abuts against the surface of the second mounting lug 62 facing the motherboard body 30. This ensures the stability and ease of installation of the support bracket 60.

[0078] As shown in Figure 21, the second mounting lug 62 is also provided with a limiting boss 63, which has a fourth clearance through hole 631, which is concentric with the third clearance through hole. The third shaft segment 93 passes through the third clearance through hole and extends into the fourth clearance through hole 631. This ensures the reliability of the second positioning stud 90 in supporting and limiting the support bracket 60.

[0079] As shown in Figure 19, the support bracket 60 has a clearance notch 64 on the side facing the motherboard body 30, and the clearance notch 64 has at least two handle grooves 641. This allows the operator to place their hands at the clearance notch 64 to operate the motherboard body 30, and it can be used when the motherboard body 30 is lifted.

[0080] As shown in Figures 19 and 20, the support bracket 60 has cable management clips 65 on both sides of the chassis base 10 in the width direction. The first end of the cable management clip 65 is connected to the side wall of the support bracket 60, and the second end of the cable management clip 65 first extends horizontally for a first preset distance, then extends upward at an angle away from the support bracket 60 for a second preset distance, and continues to extend upward at an angle closer to the support bracket 60 for a third preset distance. In this way, the cable management clips 65 serve to support and limit the movement of the wires.

[0081] As shown in Figures 2 and 10, the motherboard tray 20 includes a tray body 22 and a guide flange 23. The through-hole structure 21 is a limiting hole formed on the tray body 22. At least a portion of the limiting hole has a guide flange 23 around its periphery, and the guide flange 23 extends in a direction away from the tray body 22. Thus, the guide flange 23 helps prevent wear and even metal filings from falling off at the edge of the through-hole structure 21 during the assembly of the through-hole structure 21 and the bridge structure 12.

[0082] As shown in Figures 2 and 10, in the direction from the front window to the rear window of the server chassis module, the through-hole structure 21 sequentially includes a first sub-limiting hole segment 211, a second sub-limiting hole segment 212, and a third sub-limiting hole segment 213 that are connected. The width of the first sub-limiting hole segment 211 is greater than the width of the third sub-limiting hole segment 213. The second sub-limiting hole segment 212 is tapered. The large end of the second sub-limiting hole segment 212 is connected to the first sub-limiting hole segment 211, and the small end of the second sub-limiting hole segment 212 is connected to the third sub-limiting hole segment 213. At least the periphery of the hole in the first sub-limiting hole segment 211 is provided with a guide flange 23.

[0083] As shown in Figures 1, 4, and 17, the wall of the bearing groove 11 is provided with a second limiting protrusion 113, and the second limiting protrusion 113 has a second stop surface on the side facing the rear window of the server chassis module. A stop structure 26 is provided at the outer periphery of the motherboard tray 20. In the direction from the front window to the rear window of the server chassis module, the stop structure 26 sequentially includes a first stop flange 261, a groove structure 262, and a second stop flange 263 connected to each other. After the motherboard tray 20 is installed on the chassis base 10, the second limiting protrusion 113 is located at the groove structure 262, and the second stop surface cooperates with the groove wall surface of the groove structure 262 to constrain the motherboard tray 20 to move towards the rear window side of the server chassis module. Thus, the cooperation between the second limiting protrusion 113 and the stop structure 26 limits the movement of the motherboard tray 20 in the direction from the front window to the rear window of the server chassis module.

[0084] It should be noted that, in this application, considering that the motherboard tray 20 is slidably installed on the chassis base 10, in order to prevent the second limiting protrusion 113 from sliding a preset distance along the groove structure 262 to be installed in place, in some embodiments of this application, the second stop surface is a plane; and / or, in the direction from the front window to the rear window of the server chassis module, the extension length of the second limiting protrusion 113 is less than the extension length of the groove structure 262.

[0085] As shown in Figures 6, 8, 15, and 16, the wall of the support groove 11 is provided with cable management protrusions 13. There are at least two cable management protrusions 13, and the distance between the at least two cable management protrusions 13 and the bottom surface of the support groove 11 is equal. The at least two cable management protrusions 13 are spaced apart in the direction from the front window to the rear window of the server chassis module. A limiting groove 131 is formed on the surface of each cable management protrusion 13 on the side away from the bottom surface of the support groove 11. The server chassis module also includes a motherboard body 30 and a memory module 40. The motherboard body 30 is mounted on the motherboard tray 20. The memory module 40 is mounted on the motherboard body 30 and extends along the front window to the rear window of the server chassis module. Extending in the direction of the memory module 40, the memory module 40 has a memory partition 41; the memory module 40 also includes a flip cover 42, which is pivotally connected to the side of the memory partition 41 away from the motherboard body 30. At least when the flip cover 42 is flipped to a horizontal state, the flip cover 42, the memory partition 41, and the groove wall of the support groove 11 form a cable management channel 100. The flip cover 42 has a lug structure 421 on its edge away from the memory partition 41. The lug structure 421 has a limiting protrusion 4211 protruding towards the bottom surface of the support groove 11. When the flip cover 42 is flipped to a horizontal state, the limiting protrusion 4211 extends into the limiting groove 131. Thus, by setting the flip cover 42, the flip cover 42, the groove wall of the support groove 11, and the memory partition 41 together form a cable management channel 100, ensuring the reliability of cable positioning and guidance.

[0086] As shown in Figure 16, the flip cover 42 has a clearance groove 422 on the edge opposite to the memory partition 41. The memory module 40 also includes a handle structure 43, which is disposed at the clearance groove 422 and is set at an angle to the flip cover 42. The handle structure 43 extends upward at an angle towards the wall of the support groove 11. In this way, the handle structure 43 makes it convenient for the operator to hold the handle structure 43 to adjust the state of the flip cover 42.

[0087] It should be noted that, in this application, a torsion spring is also provided at the pivot connection between the flip cover 42 and the memory partition 41. The torsion spring is used to provide an elastic force for the flip cover 42 to flip to a horizontal state. This ensures that the flip cover 42 can automatically return to its original position, thereby ensuring the reliability of wire management.

[0088] The beneficial effects of this application are:

[0089] 1) Reduced use of rivets allows for the creation of relevant features solely through stamping, lowering costs. Compared to rivet and slotted hole structures, the larger contact area improves assembly efficiency and makes disassembly simple and convenient. An inlet mechanism facilitates quick installation of the motherboard tray onto the chassis base, further enhancing assembly efficiency. The irregularly shaped slots feature a flanged structure to prevent sharp-edge contact during installation, thus avoiding wear and metal filings and ensuring server reliability and security.

[0090] 2) The bottom of the chassis has raised bumps to directly support the CPU module. The tray has clearance slots. The chassis is thicker, providing stronger support and reducing the risk of motherboard stress and deformation. At the same time, the motherboard tray does not use rubber for support, but uses motherboard stamping bumps for support. This can prevent the stress on the motherboard from being affected by the insertion and removal of components with large insertion and removal forces, such as memory, and ensure system reliability.

[0091] 3) The side wall of the chassis is equipped with a contact protrusion shielding structure. The protrusions make corresponding contact with the inner wall of the chassis cover. The structure is simple and low in cost. The chassis base and chassis cover form a conductive connection to achieve the effect of electromagnetic shielding.

[0092] 4) Design a flip-up cover above the memory partition, which overlaps with the protrusion on the side wall of the chassis to form a cable management channel and prevent the cables from shaking and being damaged when the fan is running.

[0093] 5) Use chassis side wall cams instead of pins for limit and stop, saving costs and reducing rivet connections.

[0094] 6) The motherboard and tray are secured by maximizing the reuse of holes, allowing for multiple uses with a single hole, using studs with positioning functions. These studs secure the tray and support the M.2 bracket, improving space utilization. The M.2 bracket serves as a motherboard handle and a mounting point for the M.2 module, maximizing the use of structural components. Cable management clips on both sides are used to secure cables on the motherboard, further improving internal server space utilization. The bracket structure features hand-operated screws for quick release and easy maintenance; simply unlock the screws to access the components below.
