[0036] Relative to the above background technology, the server provided by the embodiment of the present invention includes a chassis and a board module. The chassis includes a box body and a crossbeam, the crossbeam is installed in the box body along a first direction, so that the inner cavity of the box body is constructed as a first accommodating cavity and a second accommodating cavity respectively located on both sides of the crossbeam along a second direction, wherein the second direction is perpendicular to the first direction; the board module is installed in the chassis, and the board module includes a substrate, a network card and an expansion card, the substrate adopts a plate body of an integrally formed structure, the substrate is detachably connected to the box body, the substrate is located below the crossbeam, the network card and the expansion card are both installed on the substrate, the network card and the expansion card are respectively accommodated in the first accommodating cavity and the second accommodating cavity, and the network card is fixed to the crossbeam.

[0038] The beneficial effects of the server configured in this way mainly include:

[0039] First, the conventional substrate structure adopts a split substrate structure in which the switch board and the main board are connected. In comparison, the present invention adopts an integrated substrate structure, that is, the switch board and the main board are combined into one substrate. This design eliminates a row of high-density connectors, guide pins and guide sleeves required when connecting the switch board and the main board, thereby saving production costs, which include material costs and labor costs for assembly.

[0040] Secondly, the traditional switch board needs to be assembled into the switch board frame to form a detachable mold frame and then assembled into the system. Since the switch board and the main board need to be connected through a row of high-density connectors, it is necessary to design structures such as power wrenches. In contrast, the present invention combines the main board and the switch board into a base plate, which can be assembled into the box at one time without the need for secondary assembly of the detachable mold frame where the switch board is located. This not only eliminates complex structures such as power wrenches and simplifies the overall structure of the server, but also reduces the difficulty of assembly and the failure rate after assembly.

[0041] Thirdly, the chassis using the above-mentioned setting has enough space and appropriate fixing mechanism inside to adapt to two forms of expansion cards, that is, the chassis is compatible with the first form expansion card and the second form expansion card. During assembly, if the second form connector of the baseboard is replaced with the first form connector, the chassis can be compatible with the first form expansion card. At this time, the first form expansion card is adapted inside the chassis. This design allows users to choose to use the most suitable expansion card according to actual application needs and budget without having to worry about the compatibility of the chassis. In other words, replacing the expansion card does not require replacing the entire chassis. In this way, the flexibility and compatibility of the chassis can be increased to meet the needs of different users. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0069] Please refer to FIG. 1 and FIG. 9 , the server provided in the embodiment of the present invention includes a chassis 10 and a board module 20 .

[0070] The chassis 10 includes a box body 11 and a beam 12, wherein the beam 12 is installed in the box body 11 along a first direction so that the inner cavity of the box body 11 is constructed as a first accommodating cavity 111 and a second accommodating cavity 112 respectively located on both sides of the beam 12 along a second direction, wherein the second direction is perpendicular to the first direction.

[0071] The first direction may be the Z-axis direction as shown in FIG. 1 , and the second direction may be the X-axis direction as shown in FIG. 1 .

[0072] The board module 20 is installed in the chassis 10, and the board module 20 includes a substrate 21, a network card 22 and an expansion card. The substrate 21 adopts an integrally formed structure. The substrate 21 is detachably connected to the box body 11. The substrate 21 is located below the beam 12. The network card 22 and the expansion card are both installed on the substrate 21. The network card 22 and the expansion card are respectively accommodated in the first accommodating cavity 111 and the second accommodating cavity 112, and the network card 22 is fixed to the beam 12.

[0073] Considering the sizes of the network card 22 and the expansion card along the second direction, the size of the second accommodating cavity 112 along the second direction is set to be larger than the size of the first accommodating cavity 111 along the second direction.

[0074] When assembling the above-mentioned server, first, fix the base plate 21 in the box body 11, then fix the beam 12 in the box body 11, and make the beam 12 be above the base plate 21, then, plug the network card 22 and the expansion card into the base plate 21, and fix the network card 22 to the beam 12, when the expansion card is a first form expansion card 23, then fix the first form expansion card 23 to the beam 12, and when the expansion card is a second form expansion card 24, then fix the second form expansion card 24 to the base plate 21.

[0075] It should be noted that the server provided by the present invention may be a GPU (English full name: Graphics Processing Unit, Chinese abbreviation: graphics processor) server. The expansion card in the present invention is also called an adapter card or a plug-in card, which is a hardware device that can be inserted into the expansion slot of the motherboard, and is used to increase or enhance the function of the server. Accordingly, the expansion card can be a GPU card. The above-mentioned first form expansion card 23 may be a PCIe (also known as PCI-Express, English full name: peripheral component interconnect express, a high-speed serial computer expansion bus standard) form GPU card, and the second form expansion card 24 may be an OAM (English full name: Open Accelerator Module, a standardized module form for AI accelerators) form GPU card.

[0076] Among them, the PCIe-shaped GPU card is plugged into the PCIe connector on the base plate 21 through the gold finger, which is used to transmit the signal data of the GPU card operation; the OAM-shaped GPU card usually integrates some management and monitoring functions, which are used to monitor the operating status, temperature, voltage and other parameters of the server, and provide remote management functions. According to different GPU forms, the base plate 21 can be designed to be adapted to the PCIe-shaped GPU card base plate or the OAM-shaped GPU card base plate.

[0077] In addition, the network card 22, namely the network interface card, is a hardware device for realizing network connection. The network card 22 is plugged into the base plate 21, allowing the server to connect to the network for data transmission.

[0078] In the GPU server system, the traditional base plate 21 adopts a split base plate structure in which the switch board and the main board are connected, that is, the traditional base plate 21 is connected by two boards, the switch board and the main board, and the switch board and the main board are assembled and connected by a row of high-density connectors, cables, guide pillars and guide sleeves, and power wrenches and other hardware. Under this architecture, the switch board needs to be designed as a separate detachable mold frame, and because the switch board and the main board are interconnected by high-density connectors, the plug-in and pull-out force of the connector is very large, and a power wrench needs to be designed to assemble the switch board mold frame into the server system.

[0079] To this end, power-assist wrenches are provided on both sides of the chassis 10. When the removable mold frame where the switch board is located is installed into the server system, the power-assist wrench located on the inner wall of the server chassis 10 is rotated an angle, and then the removable mold frame is pushed in. The inner walls on both sides of the chassis 10 are provided with slideways and stop features, and the pins of the removable mold frame are stuck in the wrench opening slot. Using the lever principle, the removable mold frame can be assembled into place by rotating the wrench.

[0080] This arrangement not only results in high cost for a row of high-density connectors, but also makes the overall structure of the server system complex, difficult to assemble, and has a high failure rate.

[0081] Compared with the traditional base plate 21 which uses two boards, namely, the switch board and the main board, to connect the two boards, the present invention uses an integrated structure base plate 21, that is, the switch board and the main board are combined into one base plate 21. This design eliminates a row of high-density connectors, guide pins and guide sleeves and other structures required when connecting the switch board and the main board, thereby saving production costs, which include material costs and labor costs for assembly.

[0082] Compared with the traditional switch board that needs to be assembled into the switch board frame before being assembled into the system, and requires the design of auxiliary installation such as a power wrench, the present invention combines the main board and the switch board into a base plate 21, and the base plate 21 can be assembled into the box body 11 at one time, without the need for secondary assembly of the detachable mold frame where the switch board is located. This not only eliminates complex structures such as power wrenches, simplifies the overall structure of the server, but also reduces the difficulty of assembly and reduces the failure rate after assembly.

[0083] In addition, the chassis 10 set up by the present invention has sufficient space and appropriate fixing mechanisms inside the chassis 10 to adapt to two forms of expansion cards, that is, the chassis 10 is compatible with PCIe form expansion cards and OAM form expansion cards. During assembly, if the substrate 21 replaces the second form connector with the first form connector, the chassis 10 can be compatible with the first form expansion card 23. At this time, the first form expansion card 23 is adapted inside the chassis 10. This design allows the user to choose to use the most suitable expansion card according to actual application needs and budget without having to worry about the compatibility issues of the chassis 10. In other words, replacing the expansion card does not require replacing the entire chassis 10. In this way, the flexibility and compatibility of the chassis 10 can be increased to meet the needs of different users.

[0084] Please refer to Figures 2 and 3 together. The beam 12 includes a beam body 121 and a connecting plate 122. The connecting plate 122 is arranged on a side of the beam body 121 away from the expansion card. The connecting plate 122 extends in a horizontal direction and is used to connect the network card 22 to facilitate fixing the network card 22.

[0085] Specifically, the connecting plate 122 is provided with a first connecting hole 1221, and correspondingly, the network card 22 is connected to a first fixing frame 221, and the first fixing frame 221 is provided with a second connecting hole 22121. The second connecting hole 22121 is aligned with the first connecting hole 1221 and connected through a first connecting member 222, so that the first fixing frame 221 is fixed to the connecting plate 122.

[0086] Among them, the first connecting hole 1221 can be a screw hole, the second connecting hole 22121 is a through hole or a light hole, and the first connecting member 222 is a connecting screw. In this way, the first connecting member 222 passes through the second connecting hole 22121 and is screwed into the first connecting hole 1221, so that the first fixing frame 221 is fixed to the connecting plate 122.

[0087] Please refer to Figure 4. The first fixing frame 221 includes a first fixing plate 2211, a first orifice plate 2212 and a second orifice plate 2213. The first fixing plate 2211 is in the shape of a hollow triangular plate. The first orifice plate 2212 and the second orifice plate 2213 are respectively arranged at two ends of the first fixing plate 2211 along the second direction, and the first orifice plate 2212 and the second orifice plate 2213 are arranged on the same side of the first fixing plate 2211. The first orifice plate 2212 is provided with a second connecting hole 22121, and the second orifice plate 2213 is provided with two third connecting holes 22131 spaced apart along the first direction. The axis of the second connecting hole 22121 is along the first direction, and the axes of the two third connecting holes 22131 are both along the second direction. Therefore, the axis of the second connecting hole 22121 is perpendicular to the axis of the third connecting hole 22131. The third connecting hole 22131 is used to connect the second connecting member 223 to fix the first fixing frame 221 to the network card 22.

[0088] Of course, according to actual needs, the second connecting member 223 can also be a connecting screw. The second connecting member 223 passes through the third connecting hole 22131 and is screwed to the network card 22 so that the first fixing frame 221 is fixed to the side of the network card 22 close to the expansion card.

[0089] When installing the network card 22, first fix the first fixing frame 221 to the network card 22, then plug the network card 22 into the base plate 21, and then connect and fix the first fixing frame 221 and the connecting plate 122 on the beam 12 by connecting screws to ensure the installation stability of the network card 22.

[0090] Of course, the number of the first connection holes 1221 on the connection plate 122 can be determined according to the number of network cards 22 actually to be assembled.

[0091] To facilitate fixing the cross beam 12, guide grooves 1211 are provided at both ends of the beam body 121, and the guide grooves 1211 extend along the first direction. Correspondingly, a guide member is provided in the box body 11, and the guide member can be a guide plate or a guide nail. The guide member and the guide groove 1211 are slidably matched to allow the cross beam 12 to be installed in the box body 11 along the first direction.

[0092] That is to say, when the crossbeam 12 is assembled downward in the box body 11, the guiding effect of the guide member and the guide groove 1211 can not only prevent the crossbeam 12 from being shifted in position and ensure that the crossbeam 12 is assembled downward in place, but the guide member and the guide groove 1211 themselves have a plug-in effect, so that the crossbeam 12 is positioned and assembled in the box body 11.

[0093] In addition, on the basis that the cross beam 12 and the box body 11 are guided and plugged together through the guide member and the guide groove 1211 , the cross beam 12 and the box body 11 can be further connected through the third connecting member 123 .

[0094] Specifically, both ends of the connecting plate 122 along the third direction are bent upward to form folded plates 1222. In this way, the connecting plate 122 and the folded plates 1222 at both ends form a U-shaped plate structure. The folded plate 1222 and one end of the corresponding beam body 121 are provided with at least three fourth connecting holes 1212. The box body 11 is provided with through holes 113 corresponding to the fourth connecting holes 1212 one by one. After the fourth connecting holes 1212 are aligned with the corresponding through holes 113, they are connected through the third connecting member 123 to fix the beam 12 in the box body 11.

[0095] It should be noted that the third direction, the second direction and the first direction are perpendicular to each other, and the third direction is the Y-axis direction as shown in FIG. 1 .

[0096] The fourth connection hole 1212 can be a screw hole, and the third connection member 123 can be a connection screw. In this way, the third connection member 123 passes through the through hole 113 on the box body 11 and is screwed to the fourth connection hole 1212 , so that the beam 12 is fixed in the box body 11 .

[0097] For example, a fourth connecting hole 1212 can be set on the folding plate 1222, and two fourth connecting holes 1212 can be set at the ends of the corresponding beam body 121. The three fourth connecting holes 1212 form a stable three-point connection structure after the connecting screws are screwed in, thereby ensuring the stability and firmness of the connection between the beam 12 and the box body 11.

[0098] In addition, at least two legs 124 are provided at the bottom of the crossbeam 12, and at least two legs 124 are spaced apart along the third direction. The legs 124 are L-shaped, and the legs 124 are connected to the box body 11 through a fourth connecting member 125, which is specifically a captive screw.

[0099] To this end, the base plate 21 is provided with at least two avoidance holes 211 , and the avoidance holes 211 are used to avoid the corresponding legs 124 .

[0100] In this way, when assembling the cross beam 12 , by setting connection points at both ends and the bottom of the cross beam 12 , the reliability of the connection of the cross beam 12 can be ensured.

[0101] Please refer to Figure 5 as well. The expansion card is a first form expansion card 23 (a GPU card in the form of a PCIe). When assembling the first form expansion card 23, in addition to the plug-in connection between the first form expansion card 23 and the base plate 21, the first form expansion card 23 also needs to be fixed on the beam 12. To this end, the first form expansion card 23 is connected to a second fixing bracket 231, and the second fixing bracket 231 is used to connect the beam 12 and the corresponding first form expansion card 23, so that the corresponding first form expansion card 23 is fixed on the beam 12.

[0102] Please refer to Figure 6 as well. The second fixing frame 231 is provided with a positioning hole 23121 and a fifth connecting hole 23122. Correspondingly, a positioning pin 1213 and a sixth connecting hole 1214 are provided on the beam body 121. The positioning pin 1213 is embedded in the positioning hole 23121 to achieve positioning cooperation. After the fifth connecting hole 23122 is aligned with the sixth connecting hole 1214, they are connected through the fifth connecting member 232 to fix the second fixing frame 231 to the beam body 121.

[0103] Among them, the sixth connecting hole 1214 can be a screw hole, the fifth connecting hole 23122 is a through hole or a light hole, and the fifth connecting member 232 is a connecting screw. In this way, the fifth connecting member 232 passes through the fifth connecting hole 23122 and is screwed to the sixth connecting hole 1214, so that the second fixing frame 231 is fixed to the beam body 121.

[0104] Please refer to Figure 6. The second fixing frame 231 includes a second fixing plate 2311, a third hole plate 2312 and a fourth hole plate 2313. The third hole plate 2312 and the fourth hole plate 2313 are respectively arranged at the two ends of the second fixing plate 2311 along the second direction. The third hole plate 2312 extends in the horizontal direction, and the fourth hole plate 2313 extends in the vertical direction, that is, the third hole plate 2312 is perpendicular to the fourth hole plate 2313. The third hole plate 2312 is provided with a positioning hole 23121 and a fifth connecting hole 23122, for example, two positioning waist holes are provided. The fourth hole plate 2313 is provided with at least two seventh connecting holes 23131 spaced apart along the first direction. The axis of the seventh connecting hole 23131 is perpendicular to the axis of the fifth connecting hole 23122. The seventh connecting hole 23131 is used to fix the second fixing frame 231 to the first form expansion card 23.

[0105] In this way, when assembling the first form expansion card 23, the second fixing frame 231 can be first fixed to the first form expansion card 23 through the seventh connecting hole 23131, and then the first form expansion card 23 fixed with the second fixing frame 231 can be inserted into the substrate 21, and then the second fixing frame 231 can be fixedly connected to the beam body 121, so as to ensure the installation stability of the first form expansion card 23.

[0106] Moreover, the chassis 10 further includes a bracket 13, which is installed on the side of the beam 12 away from the network card 22. The distance between the bracket 13 and the beam 12 should be equal to or slightly larger than the size of the first form expansion card 23 along the second direction, so that it is convenient to assemble the first form expansion card 23 between the beam 12 and the bracket 13.

[0107] Please refer to Figures 5 and 8 together. In order to facilitate the connection between the bracket 13 and the first form expansion card 23, the bracket 13 is provided with a positioning convex bump 131 (or a positioning convex bridge) and an eighth connection hole 132. Correspondingly, a blocking piece 233 is also connected to the side of the first form expansion card 23 away from the second fixing frame 231. The blocking piece 233 is provided with a positioning notch 2331 and a ninth connection hole 2332. The positioning convex bump 131 is embedded in the positioning notch 2331 to achieve positioning cooperation. After the eighth connection hole 132 is aligned with the ninth connection hole 2332, it is connected through the sixth connecting member 234 to fix the blocking piece 233 to the bracket 13.

[0108] Among them, the eighth connecting hole 132 can be a screw hole, the ninth connecting hole 2332 is a through hole or a light hole, and the sixth connecting member 234 is a connecting screw. In this way, the sixth connecting member 234 passes through the ninth connecting hole 2332 and is screwed to the eighth connecting hole 132, so that the blocking piece 233 is fixed to the bracket 13.

[0109] Compared with the crossbeam 12, the height of the bracket 13 is higher, and the height of the bracket 13 is close to the height of the first form expansion card 23, and the bracket 13 is provided with positioning grooves spaced along the third direction. The number of the positioning grooves is determined according to the number of first form expansion cards 23 to be installed. During installation, the first form expansion cards 23 are arranged in the positioning grooves of the bracket 13 one by one, so as to facilitate the docking of the blocking piece 233 with the corresponding positioning structure and connecting hole on the bracket 13.

[0110] In this way, when assembling the first form expansion card 23, on the one hand, the first form expansion card 23 is plugged into the second connector 215 on the substrate 21 through the gold finger, and on the other hand, the first form expansion card 23 is fixedly connected to the beam 12 and the bracket 13 on both sides along the second direction. Specifically, one side of the first form expansion card 23 along the second direction is fixedly connected to the beam 12 through the second fixing frame 231, and the other side of the first form expansion card 23 along the second direction is fixedly connected to the bracket 13 through the blocking piece 233.

[0111] It can be understood that regarding the gold finger insertion of the first form expansion card 23: the first form expansion card 23 is inserted into the second connector 215 (usually a PCIe slot) on the substrate 21 through its gold fingers (a row of metal contact points). The gold finger is designed to precisely match the contact point in the slot to ensure electrical connection; Regarding the fixed connection of the first form expansion card 23: To ensure that the first form expansion card 23 is fixed in the chassis 10 to prevent the first form expansion card 23 from loosening due to vibration during transportation or use, one side of the first form expansion card 23 along the second direction is fixedly connected to the beam 12 through a second fixed bracket 13, wherein the beam 12 is a supporting structure inside the chassis 10, used to fix and support the network card 22 and the first form expansion card 23, at the same time, the other side of the first form expansion card 23 along the second direction is fixedly connected to the bracket 13 through a baffle 233, and the baffle 233 can be designed as a metal component or plastic component that adapts to the height and width of the first form expansion card 23, and is used to fix the edge of the first form expansion card 23 on the bracket 13 of the chassis 10 to prevent it from falling off.

[0112] During assembly, the second fixing frame 231 and the baffle 233 can be fixed to the two sides of the first form expansion card 23 respectively, and then the gold fingers at the bottom of the first form expansion card 23 are aligned with the slots on the substrate 21, and then the first form expansion card 23 is gently pressed until the gold fingers are fully inserted into the slots, and then the second fixing frame 231 and the baffle 233 are fixedly connected to the beam 12 and the bracket 13 respectively to fix the first form expansion card 23.

[0113] After the installation is complete, check whether the first form expansion card 23 is firmly fixed, and perform a power-on test to ensure that the first form expansion card 23 is correctly identified by the system and functions normally.

[0114] This installation method ensures the stability and safety of the first form expansion card 23 in the chassis 10, and ensures proper connection with the interface on the base plate 21, thereby preventing poor contact or damage caused by physical impact or vibration during daily use. At the same time, by using the second fixing frame 231 and the baffle 233, the chassis 10 is designed to be compatible with expansion cards of various sizes and shapes, thereby improving the compatibility and flexibility of the chassis 10.

[0115] Please refer to FIG. 7 . The base plate 21 is provided with at least two fixing holes 212 . The fixing holes 212 are used to connect fixing members so as to fix the base plate 21 to the box body 11 .

[0116] Of course, according to actual needs, the above-mentioned fixing hole 212 can be a gourd hole, and the fixing piece can be an I-nail. The number of the fixing hole 212 and the fixing piece is two. The two fixing holes 212 are relatively arranged on the base plate 21. After the two fixing pieces pass through the two fixing holes 212 respectively, a connection is established between the base plate 21 and the bottom plate of the box body 11, thereby ensuring that the base plate 21 is fixed in the box body 11.

[0117] In order to facilitate the lifting of the substrate 21 in this state, the substrate 21 is also provided with a pair of portable connectors 213. The portable connector 213 is arranged on the side of the fixing hole 212 away from the network card 22. It should be noted that the portable connector 213 can be a portable screw, and the position of the pair of portable screws should be set in the middle of the substrate 21 to ensure the stability of the substrate 21 when the substrate 21 is lifted.

[0118] In addition, the base plate 21 is further provided with a second connector 215 , and the first form expansion card 23 is plugged into the second connector 215 . The second connector 215 is usually a PCIe slot.

[0119] Please refer to FIG. 9 and FIG. 10 together. The expansion card is a second-type expansion card 24 (OAM-type GPU card). The substrate 21 is provided with a third connector 216 . The second-type expansion card 24 is plugged into the third connector 216 .

[0120] In order to facilitate the connection between the substrate 21 of the second form expansion card 24 and the box body 11, the box body 11 is provided with a stud, and the substrate 21 is also provided with a through hole. After the through hole is aligned with the stud, it is connected through a fastener 217. The fastener 217 can be a captive screw, that is, the captive screw passes through the through hole of the substrate 21 and is screwed onto the stud of the box body 11, so that the substrate 21 is firmly fixed to the box body 11.

[0121] Please refer to FIG. 12 . To facilitate carrying the base plate 21 in this state, the base plate 21 is further provided with a pair of handles 218 located on both sides of the second-type expansion card 24 .

[0122] The handle 218 is a U-shaped handle, and the two handles 218 are detachably connected to the upper surface of the base plate 21 by screws. When it is necessary to lift the base plate 21 with the second form expansion card 24 inserted, the two handles 218 can be installed on the base plate 21, and the base plate 21 with the second form expansion card 24 inserted can be lifted by the two handles 218, so as to facilitate the base plate 21 to be installed in the box body 11.

[0123] In some embodiments, the substrate 21 is provided with a first connector 214, and the network card 22 is plugged into the first connector 214. For example, two first connectors 214 can be set at one end of the substrate 21 close to the front window 14 and close to the edges on both sides. In this way, four network cards 22 can be assembled on the substrate 21 for network connection.

[0124] Please refer to Figure 11. The chassis 10 also includes a front window 14, which is detachably connected to the case body 11. The front window 14 is rotatably connected to a pressure plate 141. The pressure plate 141 is used to be fixed to the front window 14 after rotating relative to the front window 14 to press the network card 22 to prevent the network card 22 from detaching from the first connector 214.

[0125] It should be noted that one pressing plate 141 can cover at least two network cards 22 . For a base plate 21 assembled with four network cards 22 , two pressing plates 141 can be correspondingly assembled on the front window 14 , and one pressing plate 141 correspondingly presses two network cards 22 .

[0126] The pressure plate 141 is connected to the front window 14 by rotating along the shaft in the third direction. In this way, the pressure plate 141 can rotate relative to the front window 14 along the axis of the third direction. When the pressure plate 141 is flipped upward to the outside of the front window 14, the installation space corresponding to the network card 22 can be released, which facilitates the insertion of the network card 22 into the corresponding first connector 214. After the network card 22 is inserted, the pressure plate 141 is rotated again to turn the pressure plate 141 toward the front window 14. After the pressure plate 141 is rotated into place, the pressure plate 141 is fixedly connected to the front window 14 with screws, so that the pressure plate 141 can achieve the pressing effect of the network card 22.

[0127] In addition, the detachable front window 14 is compatible with the requirements of installing the base plate 21 on the chassis 10 in two scenarios: a PCIe-type GPU card and an OAM-type GPU card.

[0128] In this way, when assembling the network card 22, the network card 22 is plugged into the first connector 214 on the substrate 21 through the gold finger. At the same time, the side of the network card 22 close to the expansion card is also fixedly connected to the beam 12 through the first fixing frame 221. In addition, the network card 22 plugged into the first connector 214 is pressed by the pressure plate 141 to ensure the stability of the installation of the network card 22.

[0129] It is understandable that, similarly, the network card 22 is inserted into the first connector 214 (usually a PCIe slot) on the substrate 21 through its gold fingers (a row of metal contact points), and the gold fingers are designed to accurately match the contact points in the slot to ensure electrical connection. Through the fixation of the first fixing frame 221 and the pressure plate 141, it can be ensured that the network card 22 is fixed in the chassis 10 to prevent the network card 22 from loosening due to vibration during transportation or use. Specifically, the side of the network card 22 close to the expansion card is fixedly connected to the crossbeam 12 through the first fixing frame 221. The crossbeam 12 serves as a supporting structure inside the chassis 10 for fixing and supporting the network card 22 and the expansion card. In order to further ensure the stability of the network card 22, the network card 22 plugged into the first connector 214 is pressed by the pressure plate 141. The pressure plate 141 is usually a metal or plastic component, which covers the network card 22 and is fixed to the chassis 10 by screws or buckles to add additional pressure to prevent the network card 22 from loosening due to vibration.

[0130] When installing the network card 22, you can first fix the first fixing frame 221 to the network card 22, then align the gold finger of the network card 22 with the slot of the first connector 214, and then gently press the network card 22 until the gold finger is fully inserted into the slot. Next, press the network card 22 with the pressure plate 141, and fix the pressure plate 141 to the front window 14, and finally fix the first fixing frame 221 to the beam 12.

[0131] After the installation is complete, check whether the network card 22 is firmly fixed, and perform a power-on test to ensure that the network card 22 is correctly identified by the system and functions normally.

[0132] This installation method ensures the stability and safety of the network card 22 in the chassis 10, preventing poor contact or damage due to physical impact or vibration during daily use. At the same time, by using the first fixing frame 221 and the pressure plate 141, the chassis 10 is designed to be compatible with network cards 22 of various sizes and shapes, thereby improving the compatibility and flexibility of the chassis 10.

[0133] The above process ensures that the network card 22 can be stably installed in the chassis 10 and correctly connected to the interface on the base plate 21. In this way, it can be ensured that the network card 22 can work reliably in various usage environments.

[0134] In addition, in some cases, the network card 22 also requires additional heat dissipation measures, such as a heat sink or a fan, to prevent overheating. At the same time, the installation of the network card 22 should also take into account electromagnetic interference shielding to ensure the stability of the network connection.

[0135] Specifically, a metal shield with good conductivity can be set between the network card 22 and the expansion card, and the metal shield can be grounded to reduce the electromagnetic interference of the expansion card to the network card 22 when it is working. The higher the magnetic permeability and the thicker the shield, the smaller the magnetic resistance and the better the magnetic field shielding effect. When the effect of a single-layer shielding does not meet the requirements, multi-layer shielding can be used. At the same time, the grounding design of the shield is the key to suppressing electromagnetic interference.

[0136] In some embodiments, a component to remind the network card 22 to be in place can also be provided. For example, a first elastic buckle is provided on the network card 22, and a second elastic buckle that cooperates with the first elastic buckle is provided on the substrate 21. When the network card 22 is installed in place, the first elastic buckle and the second elastic buckle are engaged and collided with each other to emit a click reminder sound, thereby reminding the staff that the network card 22 has been installed in place.

[0137] Of course, an indicator light indicating that the network card 22 is plugged in place may also be provided on the base plate 21. Once the network card 22 is plugged in place, the indicator light may light up to remind the staff that the network card 22 has been installed in place.

[0138] In some embodiments, the cross beam 12 is provided with a first heat dissipation air hole 1215, the front window 14 is provided with a second heat dissipation air hole 142, and a guide air duct is provided between the front window 14 and the cross beam 12, and the two ends of the guide air duct are respectively connected to the first heat dissipation air hole 1215 and the second heat dissipation air hole 142, so that the heat generated by the expansion card flows out of the chassis 10 through the first heat dissipation air hole 1215, the guide air duct and the second heat dissipation air hole 142 in sequence.

[0139] In this way, the cross beam 12 is provided with first heat dissipation holes 1215, which allow air circulation and help to extract hot air from the inside of the chassis 10. The front window 14 is provided with second heat dissipation holes 142, which allow external cold air to enter the inside of the chassis 10 to replace the extracted hot air. The guide air duct is a channel connecting the first heat dissipation holes 1215 and the second heat dissipation holes 142. The guide air duct guides the air flow to ensure that the hot air can be effectively discharged from the inside of the chassis 10.

[0140] With such configuration, the heat dissipation performance is improved by optimizing the air flow path inside the chassis 10, ensuring that the hardware inside the chassis 10 can operate stably at a suitable temperature.

[0141] In some embodiments, the inner wall of the box body 11 is provided with a first limiting structure, and the substrate 21 is provided with a second limiting structure. When the substrate 21 is installed into the box body 11 along the first direction, the first limiting structure contacts and abuts against the second limiting structure to limit the displacement of the substrate 21 along the second direction.

[0142] For example, the first limiting structure may be a raised inner wall, and the corresponding second limiting structure may be an avoidance space.

[0150] In S2 , the cross beam 12 is fixed in the box body 11 by screws at both ends and screws at the bottom, and a avoiding structure for avoiding the bottom connection structure of the cross beam 12 is provided on the base plate 21 .

[0151] In S3, when assembling the network card 22, the network card 22 is plugged into the first connector 214 on the substrate 21 through the gold finger. At the same time, the side of the network card 22 close to the expansion card is fixedly connected to the beam 12 through the first fixing frame 221. In addition, the network card 22 plugged into the first connector 214 is pressed by the pressure plate 141 to ensure the stability of the installation of the network card 22.

[0152] It should be noted that the above-mentioned network card 22 being plugged into the substrate 21 means that the network card 22 is plugged into the first connector 214 (usually a PCIe slot) on the substrate 21 through a row of metal contact points; the above-mentioned network card 22 being fixed to the crossbeam 12 means that the first fixing frame 221 connected to the network card 22 is fixedly connected to the crossbeam 12 by screws, so that on the basis of the network card 22 being plugged into the substrate 21, the network card 22 is fixedly connected to the crossbeam 12 through the first fixing frame 221 to ensure that the network card 22 is stably installed on the substrate 21.

[0153] More specifically, the steps of assembling the network card 22 include: first fixing the first fixing frame 221 on the side of the network card 22 close to the beam 12, then flipping the pressure plate 141 on the front window 14 outward, then plugging the network card 22 fixed with the first fixing frame 221 into the base plate 21, and flipping the pressure plate 141 inward and fixing it to the front window 14, and finally fixing the first fixing frame 221 to the beam 12 by screws.

[0154] In S4, when assembling the first form expansion card 23, the first form expansion card 23 is plugged into the second connector 215 on the substrate 21 through the gold finger, and the first form expansion card 23 is fixedly connected to the beam 12 and the bracket 13 on both sides along the second direction.

[0155] In S5 , when assembling the second form expansion card 24 , the second form expansion card 24 is plugged into the base plate 21 , and the second form expansion card 24 is fixed to the base plate 21 by long screws.

[0156] The beneficial effects brought about by the above-mentioned assembly method mainly include:

[0157] First, the substrate 21, the beam 12, the network card 22 and the expansion card are all connected in a detachable manner, which is convenient for subsequent upgrading and maintenance of the substrate 21, the beam 12, the network card 22 and the expansion card;

[0158] Secondly, by arranging the crossbeam 12 inside the box body 11, on the basis of ensuring that the network card 22 and the first form expansion card 23 are plugged into the corresponding connectors on the base plate 21, the network card 22 and the first form expansion card 23 can be further fixed, thereby ensuring that the network card 22 and the first form expansion card 23 are firmly installed in the box body 11, and preventing the network card 22 and the first form expansion card 23 from being displaced or damaged due to vibration or accidental collision during transportation or operation;

[0159] Third, according to the different forms of the expansion cards (the first form or the second form), they can be flexibly fixed on the beam 12 or the base plate 21, which provides more configuration options to adapt to different application requirements;

[0160] Fourthly, the above-mentioned assembly method maximizes the use of the space inside the server chassis 10, improves the space utilization rate, and ensures that the internal components of the server are correctly installed and fixed to ensure the stability and performance of the server.
