Description

Technical Field

[0001] This application relates to the field of server technology, and in particular to a management board device and a server. Background Technology

[0002] In servers, management boards are typically used to monitor and control the operating status of hardware such as processors, memory, power supplies, fans, and storage devices to enable remote operation and maintenance, fault diagnosis, and out-of-band management.

[0003] Most existing management boards adopt a horizontal layout, connecting to the motherboard via connectors, gold fingers, or cables. This layout occupies a large amount of motherboard space and can easily conflict with the placement of processors, memory, expansion cards, and other electronic components, which is not conducive to the structural layout of high-density servers. At the same time, long signal traces or intermediate connecting cables may be required between the management board and the motherboard, which not only increases assembly complexity but also easily causes high-speed signal attenuation and electromagnetic interference. In addition, horizontally arranged management boards usually have a single fixing method, and may require the removal of surrounding components during installation, disassembly, or maintenance, resulting in poor maintenance convenience. Summary of the Invention

[0004] This application provides a management board device to at least solve the problem in the related art that horizontally set management boards are prone to conflict with the arrangement of processors, memory, expansion cards and other electronic components, which is not conducive to the structural layout of high-density servers.

[0005] This application provides a management board device, including: Mounting bracket, which is used to securely connect to the motherboard of the server; A management board is fixed to the mounting bracket. The management board is provided with a board-side plug-in portion, which is used to plug into and cooperate with the board-end plug-in portion of the motherboard, so that the management board and the motherboard form an electrical connection and a signal connection. When the side-mounted connector and the end-mounted connector are vertically connected, the management board is perpendicular to the main board.

[0006] This application also provides a server, including a chassis, a motherboard, and a management board device as described in any of the above claims. The motherboard is fixedly connected to the chassis, and the management board device is fixedly connected to the motherboard. The motherboard is provided with a board end connector that engages with the board side connector.

[0007] This application addresses the technical problems of existing horizontally arranged management boards that occupy significant motherboard space, the vertical arrangement of the management board, and the ease of installation, by using mounting brackets to independently support and fix the management board and directly inserting it into the motherboard perpendicular to the motherboard. This transforms the horizontal arrangement of the management board from occupying motherboard space to utilizing the internal height of the server. Power and management signals can be transmitted through a single interface, and the mounting brackets can distribute the vibration, impact, and insertion / removal forces on the management board. Therefore, this solution resolves the existing technical issues of horizontally arranged management boards occupying large motherboard space, having long connection paths between the management board and motherboard, and having insertion structures susceptible to large mechanical loads. This achieves the technical benefits of improving server internal space utilization, shortening signal transmission paths, reducing signal transmission loss, improving the reliability of the connection between the management board and motherboard, and facilitating the installation, removal, and maintenance of the management board.

[0013] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] Embodiments of this application provide a management board device, such as Figure 2As shown, the management board device includes a mounting bracket 1 and a management board 2. The mounting bracket 1 is a structural component capable of withstanding the weight of the management board 2, insertion and removal loads, and server operating vibrations. The mounting bracket 1 is fixedly connected to the motherboard 3 of the server. The management board 2 is a board used to perform functions such as server hardware monitoring, operation control, fault diagnosis, and out-of-band management. The management board 2 is fixedly connected to the mounting bracket 1 and is maintained in a predetermined posture by the mounting bracket 1. The management board 2 is provided with a side-mounted connector 22, and the motherboard 3 is provided with a side-mounted connector 32 that is adapted to the side-mounted connector 22. The side-mounted connector 22 and the side-mounted connector 32 are inserted into each other in the vertical direction. When the insertion is completed, the board surface of the management board 2 is perpendicular to the board surface of the motherboard 3. A power supply connection path and a signal connection path are formed between the side-mounted connector 22 and the side-mounted connector 32, so that the motherboard 3 provides working power to the management board 2 and transmits server management signals between the management board 2 and the motherboard 3.

[0015] During the assembly process, first assemble the management plate 2 and the mounting bracket 1 according to... Figure 2 The relative orientations shown are combined so that the surface of the management board 2 is close to the mounting bracket 1 and the side connector 22 faces the end connector 32 of the motherboard 3. After the management board 2 and the mounting bracket 1 are fixed, the mounting bracket 1 is moved and the management board 2 is moved to the corresponding area of ​​the motherboard 3 so that the side connector 22 and the end connector 32 are aligned vertically. Then, the mounting bracket 1 and the management board 2 are pushed vertically toward the motherboard 3, and the side connector 22 gradually enters the end connector 32 until the two reach the preset insertion depth. After insertion, the mounting bracket 1 is fixedly connected to the motherboard 3, and the management board 2 remains perpendicular to the motherboard 3. When the server is powered on, the motherboard 3 supplies power to the management board 2 through the end connector 32 and the side connector 22. At the same time, the management board 2 exchanges monitoring data, control commands and status feedback information with the motherboard 3 through this connector interface.

[0016] By adjusting the management board 2 from its traditional horizontal extension to a vertical arrangement relative to the motherboard 3, the vertical space inside the chassis 4 can be utilized, reducing the space occupied by the management board 2 on the motherboard 3's planar area and the server's depth space. This allows for more ample layout space for the processor, memory, expansion cards, storage interfaces, and heat dissipation structures. The direct connection between the side connector 22 and the end connector 32 reduces connection nodes caused by intermediate cables or adapter boards, making the power supply and signal paths more compact and reducing the risk of signal attenuation and electromagnetic interference. The mounting bracket 1 provides independent support for the management board 2, distributing vibration, impact, and insertion / removal loads to the fixed area of ​​the motherboard 3, reducing the mechanical load on the connector interface, thereby improving the installation stability, signal connection reliability, and maintenance convenience of the management board 2.

[0017] In one specific embodiment, the mounting bracket 1 is provided with a mounting section 11, which extends along the length direction of the management plate 2 and forms a main area for arranging and supporting the management plate 2. A positioning part 111 is provided at one end of the mounting section 11, and a fixing part 112 is provided at the other end of the mounting section 11. The positioning part 111 and the fixing part 112 respectively cooperate with the two ends of the management plate 2 along the length direction. The positioning part 111 is used to initially position the management plate 2 during the assembly process and restrict the management plate 2 from moving relative to the mounting bracket 1 along the length direction, thickness direction, or insertion direction. The fixing part 112 is used to detachably fix the management plate 2 to the mounting bracket 1 after positioning, so that the management plate 2 and the mounting bracket 1 form a management plate assembly that can be transported and assembled as a whole.

[0018] When installing the management plate 2, first bring one end of the management plate 2 along its length close to the positioning part 111 to establish a positioning fit between the end and the positioning part 111. After the positioning part 111 restricts some degrees of freedom of the management plate 2, adjust the position of the management plate 2 along its length so that the other end of the management plate 2 gradually approaches the fixing part 112. When the management plate 2 reaches the predetermined installation position, the fixing part 112 corresponds to the other end of the management plate 2, and the operator locks the management plate 2 in the installation section 11 through the fixing part 112. When disassembling, first release the constraint of the fixing part 112 on the management plate 2, and then move the management plate 2 in the opposite direction to the assembly direction so that one end of the management plate 2 is disengaged from the positioning part 111. This assembly sequence ensures that the management plate 2 has a stable positioning foundation before fixing, eliminating the need for the operator to support the management plate 2 and calibrate multiple connection positions simultaneously.

[0019] In this specific embodiment, the positioning part 111 and the fixing part 112 act on both ends of the length direction of the management plate 2, forming an assembly logic of positioning at one end and locking at the other end. Compared with setting multiple independent fastening points around the management plate 2, this structure can reduce the number of fastening operations and reduce the risk of plate deformation caused by the accumulation of dimensional errors of multiple fastening points. The positioning part 111 first defines the position of the management plate 2, and the fixing part 112 then performs the final fixation, which can improve the assembly accuracy between the management plate 2 and the mounting bracket 1, so that the plate side insertion part 22 maintains a stable position relative to the mounting bracket 1, which is conducive to the accurate docking of the plate side insertion part 22 and the plate end insertion part 32. At the same time, the detachable fixing method facilitates the individual replacement and maintenance of the management plate 2.

[0020] In one specific embodiment, the positioning part 111 includes a supporting protrusion 1111 and a limiting structure disposed at the end of the supporting protrusion 1111; the supporting protrusion 1111 protrudes in a direction perpendicular to the mounting section 11, and the supporting protrusion 1111 creates a gap between the limiting structure and the mounting section 11 along the thickness direction of the mounting section 11. After the management plate 2 cooperates with the limiting structure, the surface of the management plate 2 is spaced apart from the mounting section 11 to avoid the management plate 2 directly contacting the mounting section 11; the supporting protrusion 1111 is mainly used to determine the protrusion position of the limiting structure relative to the mounting section 11 and the gap size between the management plate 2 and the mounting section 11, and is not used to support the weight of the management plate 2; the limiting structure is used to cooperate with one end of the management plate 2 in the length direction and restrict the position of the management plate 2 relative to the mounting bracket 1, so that the management plate 2 maintains a predetermined installation posture.

[0021] When assembling the management plate 2, first align one end of the management plate 2 along its length with the limiting structure located at the end of the support protrusion 1111, then adjust the position of the management plate 2 relative to the mounting section 11 so that one end of the management plate 2 engages with the limiting structure. As the management plate 2 moves to the predetermined position, the limiting structure restricts the position of the management plate 2, while the support protrusion 1111 causes the limiting structure to offset away from the mounting section 11, thereby maintaining a preset gap between the management plate 2 and the mounting section 11. During installation, the weight of the management plate 2 can be borne by the operator, the fixing part 112, or other cooperating structures, and the support protrusion 1111 does not serve as a load-bearing structure for the management plate 2. After the other end of the management plate 2 is fixed, the management plate 2 remains stable under the combined constraint of the positioning part 111 and the fixing part 112, and the surface of the management plate 2 will not directly contact the mounting section 11.

[0022] By providing a support protrusion 1111 extending perpendicular to the mounting section 11, the limiting structure can protrude outward relative to the mounting section 11, and maintain a gap between the management board 2 and the mounting section 11 when the management board 2 mates with the limiting structure. This avoids direct contact between the management board 2's surface, electronic components, solder joints, or circuits and the mounting section 11, reducing the risk of damage, short circuits, or wear to the surface structure of the management board 2 due to assembly compression, server vibration, or processing errors of the mounting bracket 1. This gap also provides clearance for the electronic components on the back side of the management board 2 and provides flow space for cooling airflow between the management board 2 and the mounting section 11, which is beneficial for heat dissipation on both sides of the management board 2. In addition, the support protrusion 1111 is only used to form a gap and determine the position of the limiting structure, and does not need to bear the weight of the management board 2. This avoids unnecessary limitations on its load-bearing strength, contact area, and installation position due to mistakenly using the support protrusion 1111 as a supporting structure.

[0023] In one specific embodiment, the limiting structure includes a positioning slot 1112, a first limiting member 1113, a second limiting member 1114, and two third limiting members 1115; the depth direction of the positioning slot 1112 is along the length direction of the management plate 2, and the end of the management plate 2 forms a positioning insertion part adapted to the positioning slot 1112. After the positioning insertion part is inserted into the positioning slot 1112, one end of the management plate 2 in the length direction mates with the bottom positioning surface of the bottom of the positioning slot 1112; the first limiting member 1113 is disposed in the positioning slot 1112 near the mounting section 11. On the side, the second limiting member 1114 is disposed on the side of the positioning slot 1112 away from the installation section 11. The first limiting member 1113 and the second limiting member 1114 are staggered along the insertion direction of the management board 2 and the main board 3. Two third limiting members 1115 are disposed on both sides of the positioning slot 1112 along the insertion direction. The management board 2 is provided with a recess 23 that cooperates with the third limiting member 1115. The recess 23 has a limiting surface that fits with the third limiting member 1115. The recess depth of the recess 23 is greater than the protrusion dimension of the third limiting member 1115 along the length direction of the management board 2.

[0024] During installation, first align the positioning connector of the management board 2 with the slot of the positioning slot 1112, and then push the management board 2 along its length. The positioning connector gradually enters the positioning slot 1112. One side of the management board 2 passes the first limiting member 1113, and the other side passes the second limiting member 1114. The first limiting member 1113 and the second limiting member 1114 guide the management board 2 from both sides of the thickness direction of the mounting section 11. As the management board 2 continues to move, the two third limiting members 1115 enter the corresponding slots of the management board 2. The third limiting member 1115 fits against the limiting surface inside the recess 23. When the end of the management plate 2 abuts against the bottom positioning surface, the management plate 2 reaches the predetermined position along the length direction. The first limiting member 1113 and the second limiting member 1114 restrict the displacement of the management plate 2 along the thickness direction of the mounting section 11, and the third limiting member 1115 restricts the offset of the management plate 2 along the insertion direction. Since the recess depth of the recess 23 is greater than the protrusion dimension of the third limiting member 1115, the third limiting member 1115 will not interfere with the bottom of the recess 23.

[0025] Combination Figure 2 , Figure 3 As shown, the limiting surface in the recess 23 refers to the surface in the recess 23 that contacts the upper surface of the upper third limiting member 1115, or the surface in the recess 23 that contacts the lower surface of the lower third limiting member 1115.

[0026] The positioning slot 1112 and the bottom positioning surface determine the installation reference of the management plate 2 along the length direction; the first limiting member 1113 and the second limiting member 1114 are staggered to form segmented guidance during the insertion of the management plate 2, reducing the excessive clamping or assembly resistance of the two limiting members on the management plate 2 at the same time; the two third limiting members 1115 act on both sides of the positioning slot 1112 respectively, which can improve the anti-tilting ability of the management plate 2 along the insertion direction and prevent the management plate 2 from swinging around a single positioning point during subsequent fixing; the recess 23 provides clearance space for the third limiting member 1115 and forms position constraints through the limiting surface, so that the positioning structure has the functions of guiding, limiting and anti-interference, which is conducive to improving the assembly accuracy of the management plate 2 and ensuring the stability of the positional relationship between the side insertion part 22 and the end insertion part 32.

[0027] In one specific embodiment, the fixing part 112 includes a fixing protrusion 1121 and a first connector 1122; the fixing protrusion 1121 extends in a direction perpendicular to the mounting section 11, and the management plate 2 is provided with a fixing hole 21 corresponding to the fixing protrusion 1121; the fixing protrusion 1121 may form a connecting post, a threaded post, or a boss with a connecting hole, and the first connector 1122 may be a detachable connector; when one end of the management plate 2 is engaged with the positioning part 111, the fixing hole 21 at the other end of the management plate 2 is aligned with the fixing protrusion 1121, and the first connector 1122 passes through the fixing hole 21 and connects with the fixing protrusion 1121, so that the other end of the management plate 2 is pressed against the fixing part 112, thereby completing the fixing of both ends of the management plate 2 together with the positioning part 111.

[0028] It should be noted that in this specific embodiment, the protrusion dimension of the fixed protrusion 1121 matches the protrusion dimension of the supporting protrusion 1111 to ensure that the management plate 2 and the mounting section 11 remain as parallel as possible.

[0029] In use, first, one end of the management plate 2 is inserted into the positioning slot 1112 and engages with the positioning part 111. Under the constraint of the positioning part 111, the management plate 2 moves along its length to a preset position. As the management plate 2 reaches the preset position, the fixing hole 21 moves to the corresponding area of ​​the fixing protrusion 1121. The operator can determine whether the management plate 2 is installed in place by observing the coaxial state of the fixing hole 21 and the fixing protrusion 1121. Then, the first connector 1122 is passed through the fixing hole 21 and connected to the fixing protrusion 1121. During the locking process, the first connector 1122 applies a pressing force towards the fixing part 112 to the management plate 2. When disassembling the management plate 2, first disconnect the connection between the first connector 1122 and the fixing protrusion 1121, and then remove the management plate 2 from the positioning part 111. The first connector 1122 only acts on one end of the length of the management plate 2, which can reduce the disassembly steps.

[0030] The first connector 1122 can be smoothly connected only after the fixing hole 21 and the fixing protrusion 1121 are aligned with each other. Therefore, the two can also form an installation positioning judgment structure, reducing the risk of the management board 2 being forcibly locked when it is not fully inserted into the positioning part 111. The first connector 1122 presses the management board 2 against the fixing part 112 through the fixing hole 21, which can limit the shaking of the management board 2 along the thickness direction and the insertion direction of the mounting bracket 1. One end of the management board 2 is positioned by the positioning part 111, and the other end is locked by the fixing part 112, which can obtain stable support with a small number of connectors. When the management board 2 needs to be replaced, only the first connector 1122 needs to be removed to release the main fixing relationship, which is conducive to improving server maintenance efficiency and reducing the impact of repeated disassembly and assembly on the management board 2 and the insertion interface.

[0031] In one specific embodiment, the fixing part 112 further includes a supporting part, which extends in a direction perpendicular to the mounting section 11 and forms a supporting surface for supporting the management plate 2. The supporting surface can be a plane or a partially stepped surface formed according to the edge contour of the management plate 2. The supporting part is located near the fixing protrusion 1121 so that the other end of the management plate 2 in the length direction can overlap the supporting surface before fixing. The supporting part, the fixing protrusion 1121 and the first connector 1122 together constitute the fixing area, wherein the supporting part bears the weight of the management plate 2 and part of the insertion and removal load, the fixing protrusion 1121 determines the position of the fixing hole 21, and the first connector 1122 completes the clamping connection.

[0032] When assembling the management board 2, one end of the management board 2 first engages with the positioning part 111, and the other end gradually approaches the support part as it moves along the length direction. When the management board 2 moves to the installation position, the other end of the management board 2 rests on the support surface. The support surface maintains the height relationship between the management board 2 and the fixing protrusion 1121, making it easier to align the fixing hole 21 and the fixing protrusion 1121. After the operator releases part of the lifting force on the management board 2, the management board 2 can still be supported by the support part, and then the first connector 1122 is connected. During the operation of the server, when the management board 2 is subjected to vibration, the support part can continuously support the management board 2, reducing the situation where the first connector 1122 bears the shear load alone. After the first connector 1122 is disassembled, the support surface can still temporarily support the management board 2 to prevent the management board 2 from falling suddenly.

[0033] In this specific embodiment, the supporting surface does not necessarily support the bottom surface of the management plate 2, but can also be the protruding structure near the fixing hole 21 of the management plate 2. The specific support surface is determined according to the actual situation, and will not be elaborated here.

[0034] The support part separates the load-bearing function and the connection function of the management plate 2, so that the first connector 1122 mainly undertakes the functions of pressing and preventing loosening, rather than continuously bearing the entire weight of the management plate 2; the support surface keeps the management plate 2 in position before tightening, which can improve the alignment efficiency of the fixing hole 21 and the fixing protrusion 1121, and avoid the operator from installing the first connector 1122 while holding the management plate 2; during maintenance, the support part can also reduce the risk of the plate falling when the connection is released, and improve the operational safety.

[0035] In one specific embodiment, at least one prepositioning part 12 is provided on the side of the mounting bracket 1 facing the motherboard 3. The prepositioning part 12 is located at the bottom of the mounting bracket 1 and extends along the insertion direction of the management board 2 and the motherboard 3. The motherboard 3 is provided with a positioning hole adapted to the prepositioning part 12. After the prepositioning part 12 enters the positioning hole, it can restrict the lateral and longitudinal movement of the mounting bracket 1 relative to the motherboard 3 along the plane of the motherboard 3. The prepositioning part 12 can be a positioning post 121, a positioning pin, or a protruding structure with a guide end. The size of the positioning hole can form a clearance fit or a positioning fit with a small clearance with the prepositioning part 12 while ensuring smooth insertion.

[0036] After assembling the management board 2 and mounting bracket 1 into a management board assembly, the operator moves the management board assembly to the corresponding position on the main board 3. Before the board-side insertion part 22 contacts the board-end insertion part 32, the pre-positioning part 12 is aligned with the positioning hole on the main board 3. Then, the management board assembly is moved along the insertion direction, the pre-positioning part 12 enters the positioning hole and guides the mounting bracket 1 to approach the main board 3. When the pre-positioning part 12 enters to a certain depth, the movement of the mounting bracket 1 along the plane of the main board 3 is restricted, and the board-side insertion part 22 and the board-end insertion part 32 remain basically aligned. Continue to apply force along the insertion direction, and the board-side insertion part 22 smoothly enters the board-end insertion part 32. When disassembling, the mounting bracket 1 is lifted in the opposite direction, and the pre-positioning part 12 gradually exits the positioning hole, while keeping the movement direction of the management board assembly stable.

[0037] The pre-positioning part 12 can establish a mechanical guiding relationship before the precision insertion interface contacts, avoiding collisions between the board-side insertion part 22 and the board-end insertion part 32 due to lateral misalignment. After the pre-positioning part 12 is engaged with the positioning hole, the freedom of the mounting bracket 1 along the plane of the main board 3 is restricted, and the operator only needs to continue to apply force along the insertion direction to complete the insertion, which helps to simplify the assembly action. The pre-positioning structure can also share and manage the lateral load on the board assembly, reducing the direct transmission of lateral impact to the board-side insertion part 22 and the board-end insertion part 32. In batch assembly, the pre-positioning part 12 can improve the insertion consistency and reduce the probability of terminal bending, shell damage and poor contact.

[0038] In one specific embodiment, the mounting bracket 1 includes two bracket connecting parts 13 and a second connector 14. The two bracket connecting parts 13 are located at both ends of the mounting bracket 1 along its length. Each bracket connecting part 13 is provided with a bracket connecting hole 131. The main board 3 is provided with a fixed connecting hole 31 corresponding to the bracket connecting hole 131. The second connector 14 passes through the bracket connecting hole 131 and is detachably connected to the fixed connecting hole 31. The pre-positioning part 12 includes at least two positioning posts 121. The two positioning posts 121 are spaced apart along the length of the mounting bracket 1 and protrude along the insertion direction of the board side insertion part 22 and the board end insertion part 32. The protruding length of the positioning post 121 is greater than the insertion depth of the board side insertion part 22 and the board end insertion part 32, so that the positioning post 121 enters the positioning hole of the main board 3 before the board side insertion part 22.

[0039] like Figure 6 As shown, the mounting bracket 1 can be set as a sheet metal part, and the bracket connecting part 13 is parallel to the plane where the motherboard 3 is located.

[0040] During assembly, the mounting bracket 1, along with the management board 2, is moved vertically towards the main board 3. Two spaced-apart positioning posts 121 first enter their corresponding positioning holes. Because the two positioning posts 121 are located at different positions on the mounting bracket 1, the translation and rotation of the mounting bracket 1 relative to the main board 3 are restricted. The management board assembly continues to move downwards, and the side insertion part 22 begins to enter the end insertion part 32, completing the insertion under the guidance of the positioning posts 121. When the mounting bracket 1 reaches the preset height, the bracket connection holes 131 of the two bracket connection parts 13 are aligned with the fixed connection holes 31 of the main board 3. The operator then passes the second connector 14 through the bracket connection holes 131 and connects it to the fixed connection holes 31 to complete the installation. Figure 7 As shown; during disassembly, first disconnect the two second connecting parts 14, then lift the mounting bracket 1 along the axial direction of the positioning post 121 so that the plate side insertion part 22 can be smoothly withdrawn from the plate end insertion part 32.

[0041] Two positioning posts 121 are spaced apart along the length of the mounting bracket 1, forming a larger positioning span and improving the mounting bracket 1's ability to resist in-plane rotation. The length of the positioning posts 121 is greater than the insertion depth, so that mechanical pre-positioning occurs before electrical and signal connections, which can significantly reduce the risk of collision between the plug terminals. The two bracket connecting parts 13 are respectively connected to the two ends of the mounting bracket 1, which can evenly transfer the load borne by the mounting bracket 1 to the motherboard 3 and reduce local warping of the mounting bracket 1. The second connector 14 forms a detachable connection with the fixed connection hole 31, taking into account both connection strength and maintenance convenience. The positioning posts 121, bracket connecting parts 13, and second connector 14 sequentially complete pre-positioning, insertion guidance, and final fixation, forming a clear and reliable assembly sequence.

[0042] In one specific embodiment, the mounting bracket 1 includes a mounting section 11 and two fixing sections 15, which are respectively connected to the two ends of the mounting section 11 along its length. The management board 2 is connected to the mounting section 11, and the two fixing sections 15 extend toward the connection area of ​​the motherboard 3 and are fixedly connected to the motherboard 3. At least one fixing section 15 includes a clearance section that is bent relative to the mounting section 11. The clearance section can form a single bend, a double bend, or a continuous bend structure to avoid electronic components, heat sinks, cable connectors, or other protruding structures of the motherboard 3. The fixed position of the mounting bracket 1 can also be adjusted according to the internal height and width space of the chassis 4.

[0043] During assembly, the extension path of the fixing section 15 is determined according to the layout of the electronic components of the motherboard 3. When there are electronic components between the mounting section 11 and the connection area of ​​the motherboard 3, the fixing section 15 bypasses the electronic components through the avoidance section and extends the connection position to the empty area of ​​the motherboard 3. After the management board 2 is fixed to the mounting section 11, the two fixing sections 15 are connected to the motherboard 3 respectively, so that the mounting section 11 spans the corresponding area of ​​the motherboard 3. When the server is running, the fixing section 15 transmits the weight, vibration load and insertion load of the management board 2 and the mounting section 11 to different positions of the motherboard 3. When it is necessary to adapt to different models of motherboard 3, the bending direction, number of bends or extension size of the avoidance section can be adjusted, while the mating structure between the management board 2 and the mounting section 11 can remain unchanged.

[0044] The fixed section 15 is equipped with a clearance section, which allows the mounting bracket 1 to select a reasonable connection path according to the complex component layout of the motherboard 3, reducing the risk of interference between the mounting bracket 1 and the processor, memory, heat sink or connector; the two fixed sections 15 are respectively connected to the two ends of the mounting section 11, which can improve the overall bending and torsional resistance of the mounting bracket 1 and keep the management board 2 in a stable vertical position.

[0045] Furthermore, multiple connection points can be set in the fixed section 15 for connecting with the mounting section 11. By connecting with the mounting section 11 through different connection points, the position of the fixed section 15 can be adjusted. By adjusting the fixed section 15 instead of redesigning the management board 2, the connection position between the mounting bracket 1 and the motherboard 3 can be adjusted, which can improve the adaptability of the management board device to different server platforms. The avoidance section can also allow the mounting bracket 1 to cross local height differences and transfer the fixed load to areas with higher structural strength or more space, thereby taking into account both space avoidance and connection reliability.

[0046] In one specific embodiment, at least one end of the mounting section 11 along its length is provided with an adjusting plate 151 and a rotating connection structure 152; the adjusting plate 151 is rotatably connected to the mounting section 11 via the rotating connection structure 152, and the rotation axis of the rotating connection structure 152 extends along the insertion direction of the management plate 2 and the main board 3; the adjusting plate 151 can rotate between multiple angular positions, and different angular positions correspond to different obstruction states of the adjusting plate 151 relative to the cooling airflow direction of the server; when the adjusting plate 151 is at a smaller obstruction angle, the airflow area near the management plate 2 increases, and when the adjusting plate 151 is at a larger obstruction angle, the airflow area decreases; the rotating connection structure 152 may include a rotating shaft and a shaft hole, and may also include a connecting pin and a connecting seat with a rotating fit relationship.

[0047] like Figure 9 , Figure 10 As shown, the adjusting plate 151 can be directly installed on the mounting section 11 via the rotating connection structure 152. During the process of adjusting the rotation angle of the adjusting plate 151, the position of the bracket connecting part 13 can be adjusted simultaneously. When the position of the bracket connecting part 13 is fixed, the fixing section 15 can be fixedly connected to the mounting section 11, and the adjusting plate 151 can be installed on the fixing section 15 via the rotating connection structure 152. This ensures that the rotation of the adjusting plate 151 does not affect the position of the bracket connecting part 13. The specific method can be determined according to the actual situation.

[0048] Before the server is running, the angle of the adjustment plate 151 can be adjusted according to the power consumption of the management board 2, the airflow layout of the chassis 4, and the heat dissipation requirements of the surrounding components. When the management board 2 generates a lot of heat, the adjustment plate 151 can be rotated to a position that reduces airflow obstruction, allowing more cooling airflow on the intake side to flow over the surface of the management board 2 and the gap between the management board 2 and the mounting section 11. When the management board 2 generates less heat and the adjacent components require more airflow, the adjustment plate 151 can be rotated to change the airflow distribution, allowing some airflow to flow to other heat dissipation areas. The adjustment plate 151 can also maintain the set angle through multiple positioning positions, and maintenance personnel can readjust it according to the operating temperature or airflow test results. Since the rotation axis extends along the insertion direction of the management board 2 and the motherboard 3, the rotation of the adjustment plate 151 mainly changes the frontal area relative to the lateral airflow.

[0049] The adjustment plate 151 provides airflow distribution for the management board device, enabling the mounting bracket 1 to not only perform mechanical fixation but also participate in server airflow management. By changing the angle of the adjustment plate 151, the flow area or flow rate near the management board 2 can be adjusted to adapt to different power consumption configurations and different chassis 4 airflow conditions. The adjustment plate 151 is connected to the fixed section 15, which can utilize the structural position of the fixed section 15 adjacent to the motherboard 3 and located in the airflow path, eliminating the need for a separate large-size support for the adjustment plate 151. In various server platforms, the angle adjustment can compensate for differences in fan specifications, airflow resistance, and component layout, improving the adaptability of the management board 2's heat dissipation environment and reducing local overheating or airflow waste.

[0050] In one specific embodiment, the mounting bracket 1 is equipped with a temperature detection element, a control unit, and an alarm. The temperature detection element is located in the vicinity of the management board 2 and can detect the temperature of the management board 2, the temperature near the main heat-generating components, or the air temperature around the management board 2. The control unit is connected to the temperature detection element and the alarm respectively, and the control unit pre-stores temperature thresholds or temperature change judgment conditions. The alarm can be an indicator light, a buzzer, a display prompt module, or a signal output module that sends abnormal information to the server management system. The temperature detection element sends temperature information to the control unit, and the control unit determines whether the management board 2 is in an abnormal temperature state based on the temperature information.

[0051] After the server starts up, the temperature sensor acquires the temperature of the management board 2 or the surrounding air according to a set cycle and transmits the detection results to the control unit. The control unit compares the detected temperature with the preset temperature. When the detected temperature is lower than the preset temperature, the management board device maintains normal operation. When the detected temperature reaches or exceeds the preset temperature, the control unit controls the alarm to output a temperature abnormality prompt. The prompt can be displayed through external indicator lights on the chassis 4, sound, or the server management interface. Maintenance personnel check the server fan, air duct blockage, management board 2 load, or ambient temperature according to the prompt. After the temperature returns to a safe range, the control unit can cancel the alarm or retain the abnormality record for subsequent diagnosis.

[0052] The temperature detection device can monitor the heat dissipation status of the management board 2 in real time, avoiding the inference of the local thermal status of the management board 2 based solely on the overall temperature of the server; the control unit performs judgments based on preset temperatures, and can issue timely warnings when the temperature of the management board 2 reaches a level that may affect stable operation; the alarm makes abnormal conditions easy for maintenance personnel or remote management systems to identify, which is beneficial for early handling of fan failures, air duct blockages, or abnormal device overheating; the temperature detection structure is integrated with the mounting bracket 1, which allows the detection position to be close to the management board 2 and remain stable, reducing measurement deviations caused by changes in the detection position, thereby improving the pertinence and reliability of temperature monitoring.

[0053] In one specific embodiment, the mounting bracket 1 is provided with a temperature-sensitive driving element, which can deform with temperature changes; one end of the temperature-sensitive driving element is connected to the mounting bracket 1, and the other end is connected to the adjusting plate 151; the temperature-sensitive driving element can be a bimetallic strip, a shape memory alloy part, or other thermal response structure that generates predictable displacement within a set temperature range; when the temperature of the management plate 2 rises, the temperature-sensitive driving element deforms in the first direction and drives the adjusting plate 151 to rotate, so that the adjusting plate 151 rotates to a position that increases the cooling airflow area; when the temperature of the management plate 2 decreases, the temperature-sensitive driving element recovers or generates reverse deformation, driving the adjusting plate 151 to rotate in the opposite direction.

[0054] In the initial stage of server operation, the temperature of management board 2 is low, the temperature-sensitive actuator maintains its initial shape, and the adjustment plate 151 is at its initial angle. As the load on management board 2 increases, the temperature of management board 2 and the surrounding air rises. The temperature-sensitive actuator senses the heat and gradually deforms. The deformation displacement is transmitted to the adjustment plate 151 through the connection end, and the adjustment plate 151 rotates around the rotation axis of the rotational connection structure 152. After the adjustment plate 151 rotates, the cooling airflow area near management board 2 increases, and more cooling air flows through management board 2. When the temperature of management board 2 drops, the temperature-sensitive actuator gradually returns to its original state, and the adjustment plate 151 rotates in the opposite direction to reduce excessive airflow. This adjustment process can be carried out continuously with temperature changes, or the adjustment plate 151 can be switched between several angular positions through structural limits.

[0055] The temperature-sensitive actuator uses the temperature near the management board 2 as the driving source, which can realize airflow regulation without additional motors or complex control circuits, thereby reducing the energy consumption and control complexity of the regulation structure. When the temperature of the management board 2 rises, it automatically increases the flow area, which can match the cooling capacity with the change in heat load and reduce the risk of local overheating of the management board 2 under high load conditions. When the temperature drops, the regulating plate 151 rotates in the opposite direction, which can prevent the management board 2 from occupying too much cooling airflow for a long time and redistribute the airflow to other electronic components.

[0056] In one specific embodiment, such as Figure 8 As shown, the board-side plug-in portion 22 includes a power supply terminal group and a signal terminal group spaced apart along the edge of the management board 2; the power supply terminal group is connected to the power supply circuit of the management board 2 and is used to provide working power to the management board 2 through the motherboard 3; the signal terminal group is connected to the management signal line of the management board 2 and is used to transmit server management signals; the management board 2 also includes a baseboard management controller, which is electrically connected to the signal terminal group and can collect the operating status of the processor, memory, power supply, fan, storage device and other hardware components in the server, and output control commands according to the management strategy; the board-side plug-in portion 22 may be a gold finger structure set on the edge of the management board 2, and the board-end plug-in portion 32 may be a connector that mates with the gold finger.

[0057] After assembly, the board-side connector 22 is inserted into the board-end connector 32. The power supply terminal group first forms a conductive connection with the power supply contacts of the motherboard 3 or synchronously forms a connection with the signal terminal group. When the server is powered on, the motherboard 3 provides working voltage to the management board 2 through the power supply terminal group, and the management board 2 completes power-on initialization. The baseboard management controller communicates with the management bus and related functional circuits of the motherboard 3 through the signal terminal group to obtain temperature, fan speed, voltage, current, device presence status and fault information, and adjusts the fan speed, records fault logs or sends status information to the remote management terminal according to the preset strategy. When it is necessary to disconnect the management board 2, the relevant power supply is first turned off or isolated, and then the board-side connector 22 is pulled out from the board-end connector 32.

[0058] The power supply terminal group and the signal terminal group are integrated into the same board-side plug-in part 22, which can establish the power supply connection and signal connection between the management board 2 and the motherboard 3 through a single plug-in, reducing the number of independent power supply cables and signal cables. The terminal groups are distributed at intervals along the edge of the management board 2, and can be reasonably laid out according to current carrying capacity, signal integrity and insulation distance, reducing the interference of power supply signals to high-speed management signals. The baseboard management controller communicates with the motherboard 3 through a direct plug-in path, which can shorten the signal traces, reduce the adapter interface and connection loss, and improve the stability and response speed of management signal transmission. The management board 2 can be disassembled as an independent module, which is conducive to management function upgrades, fault replacement and server platform customization.

[0059] In one specific embodiment, the mounting bracket 1 is provided with a plurality of guide holes; the guide holes penetrate through the corresponding area of ​​the mounting bracket 1, one end of the guide holes faces the management plate 2, and the other end faces the air inlet side in the direction of cooling airflow; the plurality of guide holes can be distributed at intervals along the length or height of the management plate 2, or they can be concentrated in the area corresponding to the main heat-generating device of the management plate 2; the cross-section of the guide holes can be circular, oblong, rectangular, or other shapes that are easy to process and meet the structural strength requirements; when the mounting bracket 1 is made of metal, the guide holes can be formed by stamping, cutting or die casting, and when other materials are used, they can also be formed integrally by mold.

[0060] When the server fan is running, the cooling airflow flows from the intake side to the management board device; part of the airflow flows directly over the outer surface of the management board 2, and another part of the airflow enters the gap between the management board 2 and the mounting section 11 through the guide holes; the guide holes guide the airflow on the intake side, so that the cooling airflow reaches the side of the management board 2 near the mounting bracket 1, and flows over the electronic components or soldering area on the back of the management board 2; after absorbing the heat generated by the management board 2, the airflow continues to flow along the server air duct to the exhaust side; when multiple guide holes are set for different heat-generating areas, the airflow of each area can be adjusted by the hole diameter, number or distribution density, so that the area with higher heat generation can obtain more cooling airflow.

[0061] The guide holes reduce the obstruction of cooling airflow by the mounting bracket 1, allowing the side of the management board 2 closest to the mounting section 11 to also receive effective cooling. The gap between the management board 2 and the mounting section 11, combined with the guide holes, forms a through flow path, which can improve the heat exchange capacity of both sides of the management board 2. By adjusting the shape, number, and distribution of the guide holes, the local airflow can be optimized for heat-generating components such as the baseboard management controller and power conversion devices. The guide holes can also reduce the weight of the mounting bracket 1 while ensuring the structural strength of the mounting bracket 1, thereby reducing the additional load on the motherboard 3. Compared to adding a separate fan, using the server's existing airflow for guidance can reduce energy consumption, noise, and the number of components.

[0062] In one specific embodiment, for special use cases where the server has multiple independent management needs, requires increased integration density of management boards, or needs to set up primary and backup management modules, positioning parts 111 and fixing parts 112 are provided on opposite sides of the mounting section 11. The positioning parts 111 and fixing parts 112 on each side are used to install one management board 2, so that the two management boards 2 are located on opposite sides of the mounting section 11 and together with the same mounting section 11 to form a double-sided mounting structure. The two management boards 2 can be of the same specifications or different specifications according to functional requirements. One management board 2 can be used to perform basic server management, fault monitoring and remote control functions, while the other management board 2 can be used to perform extended communication, redundancy backup, edge computing or dedicated sensing functions. The positioning parts 111 and fixing parts 112 on both sides of the mounting section 11 can be arranged correspondingly along the length direction of the management board 2, or they can be staggered according to the size and interface position of the two management boards 2 to avoid mutual interference.

[0063] During installation, firstly, one end of the first management board 2 along its length is engaged with the positioning part 111 on the first side of the mounting section 11, and then the first management board 2 is fixed by the corresponding fixing part 112. Subsequently, the mounting bracket 1 is flipped or adjusted so that the second management board 2 engages with the positioning part 111 on the second side of the mounting section 11, and is fixed by the fixing part 112 on the second side. After the two management boards 2 are installed, they are kept at a distance from the mounting section 11, and can each form an electrical and signal connection with the main board 3 or other adapter structures through the corresponding board side plug-in part 22. During maintenance, the restriction of the corresponding management board 2 by the fixing part 112 on either side can be released and the management board 2 can be removed, while the management board 2 on the other side remains in the installed state.

[0064] By setting positioning parts 111 and fixing parts 112 on both opposite sides of the mounting section 11, the two management boards 2 can be centrally installed without increasing the number of independent mounting brackets 1, thereby improving the utilization rate of the server's internal height and bracket structure. The two management boards 2 share the mounting section 11, which reduces the number of bracket parts and fixed connection positions, thereby reducing structural complexity and overall weight. At the same time, each management board 2 has an independent positioning and fixing structure, which can be installed, disassembled and maintained separately, avoiding the need to completely remove the other management board 2 when one management board 2 is being repaired. The dual-sided distribution also allows the load of the two management boards 2 to be applied relatively evenly to the mounting section 11, reducing the unilateral load on the mounting bracket 1, and is conducive to improving the integration of management functions and system redundancy reliability within the limited space of the chassis 4.

[0065] In addition to the aforementioned management board device, this application also provides a server, such as... Figure 1 As shown, the server includes a chassis 4, a motherboard 3, and a management board assembly. The chassis 4 forms an installation space for accommodating the motherboard 3, the management board assembly, the processor, memory, fans, storage devices, and other electronic modules. The motherboard 3 is fixedly connected to the chassis 4 and has a fixing connection hole 31 and a board end plug-in portion 32. The management board assembly includes a mounting bracket 1 and a management board 2. The management board 2 is fixedly connected to the motherboard 3 via the mounting bracket 1, and the board side plug-in portion 22 of the management board 2 is vertically plugged into the board end plug-in portion 32 of the motherboard 3. The mounting bracket 1 can be connected to the motherboard 3 via a bracket connecting portion 13 and a second connecting member 14. The motherboard 3 can be fixed to the chassis 4 via a motherboard tray, an I-shaped connector, or a tool-less connector.

[0066] During server assembly, the management board 2 and mounting bracket 1 are first assembled to form a management board assembly. One end of the management board 2 engages with the positioning part 111, and the other end is fixed by the fixing part 112. The management board assembly is then moved to the motherboard 3. The pre-positioning part 12 first enters the positioning hole of the motherboard 3, and the board side insertion part 22 is then inserted into the board end insertion part 32. The second connector 14 passes through the bracket connection part 13 and connects to the fixing connection hole 31. After the assembly of the management board assembly and the motherboard 3 is completed, the motherboard 3 together with the management board assembly is placed into the chassis 4, so that the motherboard 3 engages with the positioning structure and connection structure inside the chassis 4, and then is fixed by the corresponding connectors. When the server is running, the management board 2 obtains working power through the motherboard 3 and monitors the server hardware status, performs remote management, and performs fault diagnosis. When maintaining the management board 2, the connection between the mounting bracket 1 and the motherboard 3 can be disconnected and the management board assembly can be pulled out without disassembling other major electronic modules as a whole.

[0067] The management board 2 is arranged perpendicular to the motherboard 3, which reduces the area occupied by the management board 2 in the plane of the motherboard 3, providing more space for the processor, memory and expansion modules of the high-density server. The management board device is connected to the motherboard 3 as a component, and the installation and testing of the management board 2 can be completed separately before the server is assembled, improving the overall assembly efficiency. The mounting bracket 1 transfers the mechanical load of the management board 2 to the fixed area of ​​the motherboard 3. The side plug-in part 22 and the end plug-in part 32 mainly undertake the functions of electrical connection and signal connection, which helps to extend the service life of the plug-in structure. After the motherboard 3 and the chassis 4 are stably connected, the management board 2 can maintain a reliable vertical posture and cooperate with the server airflow, thus taking into account space utilization, signal transmission performance, heat dissipation efficiency and maintenance convenience, and is suitable for general servers, high-density servers, AI servers and edge servers.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application.
