[0061] like Figures 1 to 21 As shown, the server chassis module includes a chassis base 10 and a mainboard tray 20, wherein the chassis base 10 has a bearing groove 11, and a convex bridge structure 12 is provided on the bottom surface of the bearing groove 11; a via structure 21 is provided at a position of the mainboard tray 20 opposite to the convex bridge structure 12, and the convex bridge structure 12 cooperates with the via structure 21 to connect the mainboard tray 20 and the chassis base 10.

[0062] The technical solution of the present invention is applied to provide a server chassis module, including a chassis base 10 and a motherboard tray 20, wherein the chassis base 10 has a bearing slot 11, and a convex bridge structure 12 is provided on the bottom surface of the bearing slot 11; a through-hole structure 21 is provided at a position of the motherboard tray 20 opposite to the convex bridge structure 12, and the convex bridge structure 12 cooperates with the through-hole structure 21 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 cooperation of the existing I-shaped nails and gourd holes, 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, and the motherboard tray 20 and the chassis base 10 are also more convenient to disassemble, which greatly improves the convenience of disassembly and assembly between the motherboard tray 20 and the chassis base 10.

[0063] like Figure 1 , Figure 2 , Fig. 9 and Fig.10As shown, in the direction from the front window to the rear window of the server chassis module, the convex bridge structure 12 includes a first convex bridge section 121, a second convex bridge section 122, and a third convex bridge section 123 connected in sequence, the first convex bridge section 121 extends upwardly obliquely, the second convex bridge section 122 extends in the horizontal direction, the third convex bridge section 123 extends downwardly obliquely, and the width of at least part of the second convex bridge section 122 is greater than the width of the first convex bridge section 121, and the width of at least part of the second convex bridge section 122 is greater than the width of the third convex bridge section 123; in the direction from the front window to the rear window of the server chassis module, the via structure 21 includes a first convex bridge section 121, a second convex bridge section 122, and a third convex bridge section 123 connected in sequence, the first convex bridge section 121 extends upwardly obliquely, the second convex bridge section 122 extends in the horizontal direction, the third convex bridge section 123 extends downwardly obliquely, and the width of at least part of the second convex bridge section 122 is greater than the width of the third convex bridge section 123. The first sub-limiting hole segment 211, the second sub-limiting hole segment 212, and the third sub-limiting hole segment 213 are connected, and 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 side of the second sub-limiting hole segment 212 is connected to the first sub-limiting hole segment 211, and the small end side of the second sub-limiting hole segment 212 is connected to the third sub-limiting hole segment 213; wherein, the width of at least part of the second convex bridge segment 122 is smaller than the width of the first sub-limiting hole segment 211, and the width of at least part 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 a structural form that includes the first convex bridge section 121, the second convex bridge section 122, and the third convex bridge section 123 connected in sequence, and setting the via structure 21 to a structural form that includes the first sub-limiting hole section 211, the second sub-limiting hole section 212, and the third sub-limiting hole section 213 connected in sequence, the assembly convenience of the convex bridge structure 12 and the via structure 21 is ensured, and the motherboard tray 20 is quickly installed on 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 section 122 of the convex bridge structure 12 needs to pass through the first sub-limiting hole section 211, and then the motherboard tray 20 is slid along a preset direction so that the second convex bridge section 122 abuts and overlaps the second sub-limiting hole section 212 and the third sub-limiting hole section 213.

[0064] It should be noted that in the present application, the convex bridge structure 12 is stamped and formed, which is beneficial to reduce the processing and manufacturing cost of the server chassis module, and compared with the existing combination of I-shaped nails and gourd holes, the contact area between the convex bridge structure 12 and the via structure 21 is larger, which improves the assembly efficiency between the mainboard tray 20 and the chassis base 10, and the mainboard tray 20 and the chassis base 10 are also easier to disassemble, which greatly improves the convenience of disassembly and assembly between the mainboard tray 20 and the chassis base 10.

In this way, the connection reliability of the mainboard tray 20 and the chassis base 10 is achieved through the cooperation of the first fastener and the first assembly hole 1111.

[0066] Optionally, the first fastener has an external thread structure, and the first assembly hole 1111 has an internal thread structure, so that the first fastener and the first assembly hole 1111 are threadedly connected.

In this way, the first limiting convex bulge 112 and the limiting flange 25 stop and cooperate to prevent the mainboard tray 20 from moving to the side away from the groove bottom of the bearing groove 11, thereby restricting the mainboard tray 20 from moving from the groove bottom of the bearing groove 11 to the groove opening.

In this way, the first stop surface is a plane, which is conducive to increasing the stop matching area between the first stop surface and the limiting flange 25; the provision of multiple first limiting bulges 112 and multiple limiting flanges 25, and at least two of the multiple first limiting bulges 112 are respectively located at two opposite groove wall surfaces of the bearing groove 11, while ensuring that the mainboard tray 20 and the chassis base 10 have multiple stop points, ensure that the movement of the mainboard tray 20 in the direction from the bottom of the groove to the groove mouth of the bearing groove 11 is constrained; the extension length of the first limiting bulge 112 is less than the extension length of the limiting flange 25. Since the mainboard tray 20 needs to be installed on the chassis base 10 in a sliding manner, the movement of the mainboard tray 20 is prevented from causing the first limiting bulge 112 and the limiting flange 25 to fail to effectively stop and match.
