[0034] 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.
[0035] To address the issues of cumbersome and complex connection methods between motherboards and motherboard trays, and poor positioning accuracy in related technologies, this application provides a server motherboard and server chassis module.
[0036] As shown in Figures 1 to 8, the server motherboard includes a motherboard tray 10 and a motherboard body. The motherboard tray 10 has at least two first guide posts 11 protruding from it. The motherboard body has at least two first guide holes. The number of first guide holes is the same as the number of first guide posts 11, and they are matched one by one to position and install the motherboard body on the motherboard tray 10.
[0037] Applying the technical solution of this application, a server motherboard is provided, including a motherboard tray 10 and a motherboard body. The motherboard tray 10 has at least two protruding first guide posts 11; the motherboard body has at least two first guide holes. The number of first guide holes is the same as the number of first guide posts 11, and they cooperate one-to-one to position and mount the motherboard body onto the motherboard tray 10. Thus, when mounting the motherboard body onto the motherboard tray 10, positioning can be achieved first through the one-to-one cooperation of the first guide posts 11 and the first guide holes, thereby ensuring reliable positioning between the two.
[0038] As shown in Figure 7, at least two second guide posts 12 protrude from the motherboard tray 10, and the line connecting the at least two second guide posts 12 and the line connecting the at least two first guide posts 11 form a first included angle A, where the first included angle A satisfies: 0° < A < 180°. The motherboard body has at least two second guide holes, and the number of second guide holes is the same as the number of second guide posts 12, and they correspond one-to-one. Thus, by setting the line connecting the at least two second guide posts 12 and the line connecting the at least two first guide posts 11 to form a structure with a first included angle A, it is ensured that the motherboard body is matched one-to-one with the first guide posts 11 through the first guide holes, and combined with the one-to-one matching of the second guide holes with the second guide posts 12, the motherboard body and the motherboard tray 10 are limited in different directions, thereby accurately positioning and installing the motherboard body on the motherboard tray 10.
[0039] As shown in Figure 7, the height of the second guide post 12 is no greater than the height of the first guide post 11. Thus, because the first guide post 11 is relatively high, when the motherboard body is installed onto the motherboard tray 10, it is first roughly positioned by the first guide hole and the first guide post 11, and then further precisely positioned by the second guide hole and the second guide post 12, thereby ensuring the positioning accuracy of the motherboard body.
[0040] It should be noted that in this application, the first guide post 11 is detachably connected to the motherboard tray 10; and / or, the second guide post 12 is detachably connected to the motherboard tray 10. This ensures the ease of installation and removal of the first guide post 11, as well as the ease of installation and removal of the second guide post 12.
[0041] As shown in Figure 7, the motherboard tray 10 also has at least two protruding first riveting studs 13, and the motherboard body has at least two first clearance holes. The number of first clearance holes is the same as the number of first riveting studs 13, and they correspond one-to-one. The server motherboard also includes a first fastener, which passes through the first clearance holes and is threadedly connected to the first riveting studs 13. In this way, the cooperation of the first fastener and the first riveting studs 13 achieves a secure connection between the motherboard body and the motherboard tray 10, thereby ensuring the reliability of the motherboard body's positioning and installation.
[0042] As shown in Figure 7, at least two sets of stepped stud groups 14 protrude from the motherboard tray 10. Each set of stepped stud groups 14 includes at least two stepped studs 141, and the at least two sets of stepped stud groups are located at the two side edges of the motherboard tray 10. The motherboard body has at least two sets of second clearance hole groups, the number of which is the same as the number of stepped stud groups. Each set of second clearance hole groups includes at least two second clearance holes, and the number of second clearance holes in each set is the same as the number of stepped studs 141 in each set of stepped stud groups, and they correspond one-to-one. In this way, the setting of the stepped stud groups 14 further realizes the precise positioning of the motherboard body, so that the motherboard body can be accurately positioned and installed on the motherboard tray 10.
[0043] As shown in Figure 7, a second included angle B is formed between the line connecting at least two stepped studs 141 in a set of stepped studs and the line connecting at least two first guide studs 11, and the second included angle B satisfies: 0° < B < 180°. This ensures that at least two first guide studs 11 can limit the motherboard body in a first direction, at least two second guide studs 12 can limit the motherboard body in a second direction, and at least two stepped studs 141 can limit the motherboard body in a third direction. The first, second, and third directions are arranged at angles to each other. In this embodiment, referring to Figure 7, the line connecting the two first guide studs 11 is the first direction, the line connecting the two second guide studs 12 is the second direction, and the line connecting the two stepped studs 141 is the third direction.
[0044] It should be noted that in this application, the motherboard tray 10 also has a plurality of first support protrusions 15 protruding from it. The plurality of first support protrusions 15 are spaced apart and have the same height to provide support for the motherboard body. In this way, the plurality of first support protrusions 15 effectively support the motherboard body.
[0045] As shown in Figure 7, the motherboard tray 10 also has multiple first support protrusions 15, which are spaced apart and have the same height to provide support for the motherboard body. Each first support protrusion 15 has a mounting hole 151, and the motherboard body has a third clearance hole at a position opposite to the mounting hole 151. The server motherboard also includes a second fastener, which passes through the third clearance hole and is threadedly connected to the mounting hole 151. Thus, by creating mounting holes 151 on the multiple first support protrusions 15 and by having the second fastener pass through the third clearance hole and be threadedly connected to the mounting hole 151, a secure connection to the motherboard body is achieved.
[0046] It should be noted that in an embodiment of this application (not shown), only the first support protrusion 15 has an assembly hole 151, and the second fastener passes through the third clearance hole and is threaded to the assembly hole 151, thereby achieving a fastening connection to the motherboard body, without the need to set the first riveting stud 13 on the motherboard tray 10.
[0047] It should be noted that in one embodiment of this application (not shown), only a first riveting stud 13 is provided on the motherboard tray 10. Through the cooperation of the first fastener and the first riveting stud 13, a tight connection between the motherboard body and the motherboard tray 10 is achieved, thereby ensuring the reliability of the positioning and installation of the motherboard body.
[0048] In some embodiments, the first support convex hull 15 is a circular convex hull.
[0049] As shown in Figures 7 and 8, the motherboard tray 10 has square clearance holes 16, and a second support protrusion 17 is also provided on the motherboard tray 10, located on the outer periphery of the square clearance holes 16. Multiple second support protrusions 17 are provided, spaced apart circumferentially around the square clearance holes 16; or, the second support protrusions 17 are annular protrusions extending continuously circumferentially around the square clearance holes 16. In this way, the second support protrusions 17 effectively support the heavy heatsink on the motherboard body.
[0050] Furthermore, as shown in Figure 8, there are multiple second support protrusions 17, each of which is L-shaped and located at the corner of the square clearance hole 16. The width K of the L-shaped second support protrusion 17 in the direction away from the square clearance hole 16 satisfies: 5mm ≤ K ≤ 8mm; and / or, the extension length W on one side of the L-shaped second support protrusion 17 satisfies: 10mm ≤ W ≤ 25mm. Thus, by reasonably optimizing the shape and size of the second support protrusions 17, while ensuring that the second support protrusions 17 do not occupy a large installation space on the motherboard tray 10, they can effectively support the heavy heatsink on the motherboard body.
[0051] As shown in Figures 1 to 6, the server chassis module includes a chassis base 1 and a server motherboard 2, which is the same as described above and below. The motherboard tray 10 of the server motherboard 2 is provided with multiple sets of first guide slides, and the chassis base 1 is provided with multiple sets of second guide slides. The multiple sets of second guide slides correspond one-to-one with the multiple sets of first guide slides. This ensures the reliable connection between the chassis base 1 and the server motherboard 2.
[0052] As shown in Figures 1, 2, and 6, the multiple sets of first guide sliding components include a first group of first guide sliding components, each containing multiple gourd holes 18 spaced apart along the length and width of the motherboard tray 10. The multiple sets of second guide sliding components include a first group of second guide sliding components, each containing multiple I-beams 101. Each I-beam 101 corresponds one-to-one with a gourd hole 18, and each gourd hole 18 slides in engagement with its corresponding I-beam 101. This sliding engagement of each gourd hole 18 with its corresponding I-beam 101 ensures that the server motherboard 2 can be accurately positioned and installed on the chassis base 1.
[0053] As shown in Figures 1, 3, and 6, the multiple sets of first guide sliding components include a second set of first guide sliding components. The second set of first guide sliding components includes multiple guide holes 19, which are spaced apart along the length and width of the motherboard tray 10. The multiple sets of second guide sliding components include a second set of second guide sliding components, which includes multiple guide protrusions 102. The multiple guide protrusions 102 are corresponding one-to-one with the multiple guide holes 19, and each guide hole 19 slides in cooperation with its corresponding guide protrusion 102. The guide hole 19 includes a first guide segment 191 and a second guide segment 192 that are connected. Both the first guide segment 191 and the second guide segment 192 extend along the sliding direction of the motherboard tray 10, and the width of the first guide segment 191 is greater than the width of the second guide segment 192. The guide protrusion 102 slides from the first guide segment 191 to the second guide segment 192 to limit the motherboard tray 10 on the chassis base 1. In this way, the cooperation of the guide hole 19 and the guide protrusion 102 ensures that the server motherboard 2 can be accurately positioned and installed on the chassis base 1.
[0054] As shown in Figures 1, 2, 4, and 5, the multiple sets of first guide sliding components include a third set of first guide sliding components, which includes multiple oblong holes 110. The oblong holes 110 are spaced apart along the length and width of the motherboard tray 10. The multiple sets of second guide sliding components include a third set of second guide sliding components, which includes multiple second riveting studs 103. The multiple second riveting studs 103 are arranged one-to-one with the multiple oblong holes 110, and each second riveting stud 103 slides in cooperation with its corresponding oblong hole 110. The motherboard body of the server motherboard 2 is also provided with multiple fourth clearance holes, which correspond one-to-one with the multiple oblong holes 110. The server chassis module also includes multiple third fasteners, which are arranged one-to-one with the multiple fourth clearance holes. The third fasteners pass through the fourth clearance holes and are threaded in cooperation with the second riveting studs 103. In this way, the cooperation of multiple second riveting studs 103 and multiple oblong holes 110 ensures that the server motherboard 2 can be accurately positioned and installed on the chassis base 1.
[0055] It should be noted that in this application, the sliding stroke of the I-shaped nail 101 in the gourd hole 18, the sliding stroke of the guide protrusion 102 in the guide hole 19, and the sliding stroke of the second riveting stud 103 in the waist-shaped hole 110 are all equal, and the sliding directions are all consistent.
[0056] This application provides a server motherboard, including a motherboard tray 10 and a motherboard body. The motherboard tray 10 has at least two protruding first guide posts 11; the motherboard body has at least two first guide holes. The number of first guide holes matches the number of first guide posts 11, and they cooperate one-to-one to position and mount the motherboard body onto the motherboard tray 10. Thus, when mounting the motherboard body onto the motherboard tray 10, positioning can be achieved first through the one-to-one cooperation of the first guide posts 11 and the first guide holes, thereby ensuring reliable positioning between the two.
