Description

Technical Field

[0001] This application relates to the field of server technology, and in particular to a tool-free expansion card installation and removal device and a server. Background Technology

[0002] As servers and computing devices evolve towards higher performance and greater integration, expansion cards, as crucial components for expanding system functionality, are widely used in storage management, network communication, data acceleration, and other specialized areas. Expansion cards typically connect to the motherboard via standardized bus interfaces, modularizing specific functions to share the computing and management load of the main processor, thereby improving overall system performance and operating efficiency.

[0003] Expansion cards are typically installed using a mounting bracket and screws. Specifically, the expansion card itself is first secured to a metal bracket with screws, then inserted into the adapter card's socket, and finally the bracket is screwed onto the server chassis's rear window or corresponding structural component. When server rear window space is limited and multiple interfaces or functional modules are already configured, this expansion card installation method has significant limitations in terms of space adaptability.

[0004] Some expansion cards require multiple data or power cables to be connected to one end during use. Existing general-purpose expansion card structures often lack effective support or restraint design at the rear of the card. After cable connections are completed, the card is prone to sag due to the weight of the cables or external forces. During server operation, transportation, or exposure to vibration or shaking, the expansion card may become loose, leading to poor interface contact, unstable signals, and other problems, affecting the reliability and operational stability of the server system. Summary of the Invention

[0005] The purpose of this application is to solve the aforementioned technical problems by providing a tool-free expansion card installation and removal device and server, thereby improving the stability of expansion card installation and enhancing the spatial arrangement of expansion cards to avoid excessive server space occupation. To achieve the above objectives, the technical solution of this application is as follows: In a first aspect, this application provides a tool-free expansion card removal and installation device for removing and installing expansion cards. The tool-free expansion card removal and installation device includes a module base plate, a module bracket, and a support assembly. The module bracket is disposed on the module base plate and is configured to be movably connected to the side wall of the chassis. At least one expansion card is installed on the module bracket. The support assembly includes a sliding plate and a support seat disposed on the sliding plate. The sliding plate is slidably disposed relative to the module base plate so that the support seat can move closer to or away from the expansion card. The side wall of the support seat is provided with a support groove corresponding to the expansion card. The two ends of the support groove are through-connected, and the opening of the support groove faces the expansion card. One end of the expansion card is connected to the module bracket, and the other end of the expansion card is supported in the support groove.

[0006] Secondly, this application provides a server, including a chassis and the aforementioned tool-free expansion card removal and installation device disposed within the chassis.

[0007] Compared with existing technologies, the advantages of the tool-free expansion card installation / removal device and server in this application are mainly reflected in: The module bracket connects to the side wall of the chassis, avoiding space compression of other existing modules and achieving a more rational layout of the internal space of the chassis. This also improves the spatial adaptability of the disassembly and assembly devices. The support component effectively supports and positions the expansion card at its load-bearing position. Both ends of the expansion card are connected to the module bracket and the support slot, respectively, to achieve balanced support for the expansion card and prevent displacement or misalignment at its load-bearing position. When a cable is installed at the other end of the expansion card, the support slot ensures that the expansion card remains stable and does not fail due to external vibration or shaking.

[0010] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0011] Example 1 This embodiment provides a tool-free expansion card installation and removal device for installing and removing expansion card 11. Expansion card 11 is inserted into the slot of adapter card 12 to achieve electrical connection. Expansion card 11 can be a Host Bus Adapter (HBA card), which is a circuit board or integrated circuit adapter that provides input / output processing and physical connection between the server and storage device. HBA cards reduce the burden on the main processor in data storage and retrieval tasks, thus improving server performance. An HBA card and its associated disk subsystem can be referred to as a disk channel. In other words, the HBA card is the link between the storage and computing layers, and therefore is widely used on storage servers.

[0012] In related technologies, the HBA card is mounted on a mounting bracket, and the HBA card is fixed to the bracket with screws. Then, the entire module, similar to a PCIe expansion card, is inserted into another structural component mold and fixed with screws. The mounting bracket is installed on the rear window of the server. However, due to limited space in the rear window, the mounting bracket is not effective if other components are already installed. Furthermore, this structure for fixing the HBA card internally occupies a significant amount of space. The HBA card, as an expansion card 11 for managing hard drives, requires a cable to be inserted at its rear. Currently, the design of common PCIe expansion cards directly inserts the cable at the rear. Because the rear bears the weight of the cable, vibrations during server operation or transport can easily cause the connection between the expansion card 11 and the cable to loosen, leading to poor signal strength. Therefore, this embodiment improves the disassembly and assembly device of the expansion card 11 to solve the above problems, enabling tool-free quick disassembly and assembly of the expansion card 11, ensuring the stability of the expansion card 11 installation, and rationally arranging the internal space of the chassis where the expansion card 11 is located. The following is a detailed description. The height direction of the chassis is defined as the first direction, the length direction of the chassis is defined as the second direction, and the width direction of the chassis is defined as the third direction. The second and third directions can be interchanged, that is, the width direction of the chassis can also be the second direction, and the length direction of the chassis can also be the third direction. The first, second, and third directions are perpendicular to each other.

[0013] like Figures 1-4 As shown, the tool-free expansion card installation and removal device includes a module base plate 21, a module bracket 22, and a support assembly 23. The module bracket 22 is mounted on the module base plate 21 and is movably connected to the side wall 81 of the chassis. At least one expansion card 11 is mounted on the module bracket 22. The support assembly 23 includes a sliding plate 24 and a support base 4 mounted on the sliding plate 24. The sliding plate 24 is slidably mounted relative to the module base plate 21. The side wall of the support base 4 is provided with a support groove 41 corresponding to the expansion card 11. One end of the expansion card 11 is connected to the module bracket 22, and the other end of the expansion card 11 is supported in the support groove 41.

[0014] The module base plate 21 and the module bracket 22 are detachably connected. The module base plate 21 has a roughly rectangular plate structure, and the module bracket 22 has a roughly L-shaped cross-section. The module base plate 21 and the module bracket 22 are assembled into a semi-enclosed frame body so that the expansion card 11 can be housed in the semi-enclosed frame body. This avoids the traditional drawer-type frame structure that completely surrounds the expansion card 11. The semi-enclosed frame body can effectively reduce the volume occupation, and at the same time facilitate the intuitive and quick installation and removal of the expansion card 11.

[0015] The semi-enclosed frame reduces overall weight, and the module bracket 22 is suspended from the side wall 81 of the chassis, achieving lightweight installation and reducing the load on the side wall 81. The disassembly and assembly device can be installed on any side wall of the chassis, and can be suspended from the side wall 81 arranged in a second direction and / or a third direction, avoiding direct installation on the bottom wall 82 of the chassis. It is not limited to the rear window position of the chassis, effectively solving the problem of limited installation space for the disassembly and assembly device. The disassembly and assembly device can be installed in the internal space of the chassis more flexibly. Positioning can be achieved by suspending the disassembly and assembly device, making assembly more convenient and operable.

[0016] One or more expansion cards 11 can be installed on the module bracket 22. This embodiment uses two expansion cards 11 installed on the module bracket 22 as an example. The two expansion cards 11 are arranged at intervals along a first direction, and both expansion cards 11 are inserted into corresponding slots on the adapter card 12. One end of the adapter card 12 along a third direction is connected to the module bracket 22, and the third end of the adapter card 12 has a slot. One end of the expansion card 11 along a second direction is connected to the module bracket 22. The insertion direction of the expansion card 11 into the adapter card 12 is consistent with the third direction. The support component 23 is located at the other end of the expansion card 11 along the second direction. The sliding direction of the sliding plate 24 is consistent with the second direction. One end of the expansion card 11 along the third direction is connected to the slot of the adapter card 12, and the other end of the expansion card 11 along the third direction is supported in the support groove 41.

[0017] For example, the support slot 41 is through-hole at both ends, with the opening of the support slot 41 facing the expansion card 11. By adjusting the moving position of the sliding plate 24, the position of the support base 4 supporting the expansion card 11 is changed. The number of support slots 41 is the same as the number of expansion cards 11, so that multiple support slots 41 are correspondingly engaged with multiple expansion cards 11. Thus, regardless of whether the expansion card 11 slides into the opening of the support slot 41 or slides into the end of the support slot 41, engagement can be achieved. The support base 4 is positioned at one end of the expansion card 11 along a third direction or at one end of the expansion card 11 along a second direction. The end of each expansion card 11 away from the module bracket 22 is effectively supported and positioned, avoiding excessive weight on the connecting cables of the expansion card 11, which could cause positioning deviation of the expansion card 11 and lead to poor signal transmission.

[0018] In other possible implementations, the sliding plate 24 slides along a third direction so that the multiple support slots 41 are engaged with the multiple expansion cards 11. The support base 4 is positioned at one end of the expansion card 11 along the third direction or at one end of the expansion card 11 along the second direction. The setting position of the support base 4 is more flexible, which is conducive to avoiding other modules in the internal space of the chassis and making the space arrangement more reasonable.

[0019] In this embodiment, the module bracket 22 is suspended to the side wall 81 of the chassis, avoiding installation entirely on the bottom wall 82 of the chassis, which would compress the space of other existing modules. This achieves a reasonable layout of the internal space of the chassis, improves the convenience of setting up the disassembly and assembly device in the chassis, and enhances the spatial adaptability of the disassembly and assembly device. The support component 23 effectively supports and positions the load-bearing position of the expansion card 11. The two ends of the expansion card 11 are respectively connected to the module bracket 22 and the support groove 41 to achieve balanced support for the expansion card 11 and prevent the expansion card 11 from moving or misaligning at its load-bearing position. When a cable is provided at the other end of the expansion card 11, the support groove 41 can ensure that the expansion card 11 is in a stable state and will not fail due to external vibration or shaking.

[0020] In one specific implementation, such as Figure 1 , Figure 5 As shown, multiple expansion cards 11 are arranged at intervals along a first direction. Multiple adjustment parts 42 that are movable along the first direction are provided on the side wall of the support base 4. Adjustable support grooves 41 are formed between adjacent adjustment parts 42. The multiple support grooves 41 are correspondingly arranged with the multiple expansion cards 11.

[0021] Since there are multiple expansion cards 11, the number of support slots 41 should be the same as the number of expansion cards 11 to ensure that each expansion card 11 is positioned within a support slot 41. To achieve reusability and quick positioning of the support base 4, multiple adjustment parts 42 are provided on the side wall of the support base 4. The number of adjustment parts 42 is twice the number of expansion cards 11, so that the support slot 41 formed between two adjacent adjustment parts 42 can support one expansion card 11.

[0022] The width of the support groove 41 is its height along the first direction. The width of the support groove 41 can be adjusted in various ways. The adjustment part 42 can be moved along the first direction. The connection between the adjustment part 42 and the support base 4 can be snap-fit, screw-fit, etc.

[0023] In order to allow the expansion card 11 to smoothly enter the support groove 41, the two ends of the adjustment part 42 have inclined surfaces, and the adjacent inclined surfaces form a flared mouth 43 at the end of the support groove 41. The larger diameter end of the flared mouth 43 is set away from the support groove 41, and the smaller diameter end of the flared mouth 43 is connected to the support groove 41. The expansion card 11 slides smoothly into the support groove 41 along the flared mouth 43, avoiding the problem of sliding obstruction.

[0024] For example, the module base plate 21 is provided with a plurality of guide posts 26 arranged in the same direction, and the sliding plate 24 is provided with a sliding groove 25 corresponding to the guide post 26. The sliding plate 24 is movable along the guide post 26 through the sliding groove 25.

[0025] The guide post 26 can be an I-beam, and the sliding groove 25 has a roughly elongated structure. One end of the sliding groove 25 has a round hole that fits the I-beam. When the sliding plate 24 is in contact with the module base plate 21, the I-beam can pass through the round hole, so that when the sliding plate 24 is moved, the sliding groove 25 guides along the I-beam.

[0026] The multiple guide posts 26 are arranged in the same direction, which can guide the sliding plate 24 to move in the same direction. When the sliding plate 24 needs to move in the second direction, the multiple guide posts 26 are arranged at intervals in the second direction. When the sliding plate 24 needs to move in the third direction, the multiple guide posts 26 are arranged at intervals in the third direction. In order to improve the smoothness of the movement of the sliding plate 24, the multiple guide posts 26 can be arranged in an array to ensure that the sliding plate 24 does not deviate when it moves along the guide displacement of the multiple guide posts 26.

[0027] In one specific implementation, such as Figure 1 , Figure 5 As shown, the support base 4 is provided with a through groove 44 and an adjusting member 45. The adjusting member 45 is disposed in the through groove 44 and is movable along the first direction. One end of the adjusting member 45 is connected to the adjusting part 42, and the other end of the adjusting member 45 is limited to the side wall of the support base 4 away from the adjusting part 42, so that the adjusting part 42 is positioned at a set height.

[0028] The through groove 44 is provided to pass through the support base 4 in the third direction. The through groove 44 has a roughly elongated structure so that the adjusting member 45 can move in the first direction. By cooperating with the adjusting part 42, the position of the adjusting member 45 relative to the through groove 44 is changed, thereby positioning the adjusting part 42 to move to the set height to meet the corresponding snap-fit ​​requirement of the support groove 41 and the expansion card 11.

[0029] For example, the adjusting member 45 can be a bolt and nut assembly, with the adjusting part 42 bolted to the adjusting part 42 and the nut disposed on the side wall of the support base 4 away from the adjusting part 42. By tightening the nut, the adjusting part 42 is securely connected to the support base 4, and by loosening the nut, the adjusting part 42 can be moved and adjusted relative to the support base 4 along the through groove 44.

[0030] The bottom of the support base 4 is detachably connected to the top of the sliding plate 24. The connection method can be snap-fit ​​or screw-fit, thereby enabling the support base 4 and the sliding plate 24 to move synchronously.

[0031] To effectively reduce the space occupied by the sliding plate 24 on the module base plate 21, multiple expansion cards 11 are stacked at intervals along the first direction. A gap is left between the bottommost expansion card 11 and the module base plate 21, and the sliding plate 24 is placed in the gap and slides against the module base plate 21. The support base 4 is located at the edge of the multiple expansion cards 11, and plays an effective supporting and positioning role.

[0032] Furthermore, such as Figure 3 , Figure 4 As shown, a second fixing member 27 is provided on the sliding plate 24. The second fixing member 27 is detachably connected to the module base plate 21. The detachable connection can be achieved by screwing, snap-fitting, etc. For example, the second fixing member 27 is a bolt. The module base plate 21 is provided with corresponding holes for the second fixing member 27. When the sliding plate 24 moves the support base 4 into position, the second fixing member 27 is fixed to the module base plate 21 by turning the knob, ensuring the positioning stability of the sliding plate 24 and preventing displacement after positioning.

[0033] In one specific implementation, such as Figure 1 , Figure 3 As shown, the module bracket 22 includes a first bracket 51 and a second bracket 53 connected at an angle. The first bracket 51 is configured to be connected to the side wall 81 of the chassis. The adapter card 12 is installed on the first bracket 51. One end of the expansion card 11 is connected to the second bracket 53. The support assembly 23 is located at the other end of the expansion card 11. The sliding direction of the sliding plate 24 is parallel or perpendicular to the insertion direction of the slot connecting the expansion card 11 to the adapter card 12. The edge of the expansion card 11 away from the slot of the adapter card 12 is correspondingly set with the support groove 41.

[0034] The first bracket 51 and the second bracket 53 are connected at a right angle. Both the first bracket 51 and the second bracket 53 are connected to the module base plate 21 and are perpendicular to the module base plate 21. The first bracket 51 and the second bracket 53 are detachably connected, and the connection method can be screw connection, snap connection, etc.

[0035] The first bracket 51 is connected to the side wall 81 of the chassis, thereby enabling the overall module bracket 22 to be suspended on the side wall 81 of the chassis, so that the module base plate 21 is located above the bottom wall 82 of the chassis, and the disassembly and assembly device does not occupy the space of the bottom wall 82 of the chassis.

[0036] The adapter card 12 is mounted on the first bracket 51, and the mounting method can be either snap-fit ​​or screw-fit. The length of the adapter card 12 is adapted to the length of the first bracket 51 to avoid the adapter card 12 being too long and thus affected by the position of the second bracket 53. The adapter card 12 is provided with slots arranged at intervals along the first direction. The number of slots is the same as the number of expansion cards 11. The multiple slots are arranged parallel to each other, so that multiple expansion cards 11 can be inserted into the slots along the third direction.

[0037] As described above regarding the sliding direction of the sliding plate 24, the sliding plate 24 can move along the second direction or the third direction. That is, the sliding direction of the sliding plate 24 is parallel or perpendicular to the insertion direction of the expansion card 11. Regardless of whether the sliding direction of the sliding plate 24 is along the second direction or the third direction, it should not affect the accurate engagement of the support slot 41 and the expansion card 11. The sliding direction setting of the sliding plate 24 is more flexible and less likely to be limited by space.

[0038] Preferably, the support base 4 and the adapter card 12 are located at both ends of the expansion card 11 along the third direction, that is, on opposite sides of the expansion card 11, which can effectively prevent the expansion card 11 from coming loose from the slot of the adapter card 12. The support base 4 can ensure that the expansion card 11 is stably supported while being accurately positioned in the support groove 41 and the slot.

[0039] In one specific implementation, such as Figure 1 , Figure 2 As shown, one end of the expansion card 11 is provided with a insert 61, the second bracket 53 is provided with a side rest 62 away from the end face of the first bracket 51, a rotating piece 63 is rotatably connected to the side rest 62, a first fixing member 65 is provided on the rotating piece 63, the insert 61 extends between the side rest 62 and the rotating piece 63, and the first fixing member 65 is detachably connected to the side rest 62.

[0040] The second bracket 53 has a protrusion 54 on its side wall, and a slot 55 is provided in the protrusion 54. The slot 55 is used to guide the insert 61 to be positioned on the second bracket 53. The expansion card 11 has an insert 61 at one end along the second direction. The insert 61 is adapted to the width of the expansion card 11. One end of the insert 61 is inserted into the slot 55, and the other end of the insert 61 abuts against the side abutment 62. The insert 61 has an approximately L-shaped structure. The number of inserts 61 is the same as the number of expansion cards 11. Correspondingly, the second bracket 53 has a plurality of protrusions 54 arranged at intervals along the first direction. Each protrusion 54 is connected to each insert 61, so that a preset distance is formed between adjacent expansion cards 11.

[0041] A rotating shaft 64 is provided at both ends of the side rest portion 62 along the first direction. The rotating piece 63 is mounted on the rotating shaft 64 at both ends along the first direction, thereby realizing the rotation of the rotating piece 63 relative to the side rest portion 62. When the rotating piece 63 is rotated open relative to the side rest portion 62, the end of the insert 61 can abut against the side rest portion 62; when the rotating piece 63 is rotated closed relative to the side rest portion 62, the rotating piece 63 presses the end of the insert 61 onto the side rest portion 62.

[0042] The first fixing member 65 can be a bolt, and the side rest 62 is provided with holes corresponding to the first fixing member 65. When the rotating piece 63 presses the end of the insert 61 onto the side rest 62, the first fixing member 65 is turned to tighten the rotating piece 63 and the side rest 62. One end of the insert 61 is positioned in the socket 55, and the other end of the insert 61 is positioned between the side rest 62 and the rotating piece 63, so that the insert 61 is limited in the third direction, ensuring the installation stability of the expansion card 11. By setting a rotatable rotating piece 63, quick operation is achieved, which helps to improve the assembly efficiency of the expansion card 11, and no additional tools are required.

[0043] In one specific implementation, such as Figure 6 , Figure 7 As shown, the tool-free expansion card disassembly and assembly device also includes a first support part 71 and a second support part 73. A suspension part 52 is provided on the first bracket 51. Both the suspension part 52 and the first support part 71 are configured to be connected to the side wall 81 of the chassis. The suspension part 52 and the first support part 71 are spaced apart along a first direction. The first support part 71 is used to support the module base plate 21 and limit one end of the module base plate 21 along a second direction. The second support part 73 is configured to be connected to the bottom wall 82 of the chassis and is used to connect the other end of the module base plate 21 along the second direction.

[0044] The suspension part 52 protrudes from the first bracket 51 in the direction away from the expansion card 11. The suspension part 52 abuts against the side wall 81 of the chassis. The suspension part 52 has a suspension hole 56, which is roughly L-shaped. The side wall 81 of the chassis is provided with a mating part 83 corresponding to the suspension part 52. The mating part 83 extends into the suspension hole 56, and the suspension part 52 is guided and positioned along the mating part 83. The way the suspension part 52 protrudes relative to the first bracket 51 allows the mating part 83 to have space to pass into the suspension hole 56, avoiding positional interference of the mating part 83 with the adapter card 12 on the first bracket 51.

[0045] Specifically, the mating part 83 can be an I-beam nail, and correspondingly, one end of the suspension hole 56 is a round hole, which can effectively avoid the mating part 83 so that the mating part 83 can pass through the suspension hole 56, thereby realizing the guiding fit between the suspension hole 56 and the mating part 83, ensuring the stability of the module bracket 22 suspended on the side wall 81 of the chassis and the ease of assembly.

[0046] The number of suspension parts 52 is adapted to the length of the first bracket 51 along the second direction. The first bracket 51 is provided with multiple suspension parts 52, so that the first bracket 51 is mounted in a balanced and stable manner on the side wall 81 of the chassis. Two suspension parts 52 can be arranged near the two ends of the first bracket 51 along the second direction.

[0047] For example, such as Figure 6As shown, the first support part 71 has a roughly L-shaped structure. One side of the first support part 71 is connected to the side wall 81 of the chassis, and the connection method can be screwed, snap-fit, etc. The other side of the first support part 71 is used to support the module base plate 21. A baffle 72 is provided at the end of the first support part 71 facing the second bracket 53 in the third direction. The baffle 72 is used to abut against the second bracket 53 so that the upper limit of the second support part 73 in the third direction is located at the baffle 72. The first support part 71 is located below the mating part 83. The mating part 83 plays the role of suspending the upper part of the first bracket 51, and the first support part 71 plays the role of supporting the module base plate 21, thereby improving the structural stability and support strength of the overall disassembly and assembly device.

[0048] like Figure 6 As shown, the second support 73 is disposed on the bottom wall 82 of the chassis and is used to support the positioning module base plate 21. Specifically, a third fixing member 74 is provided on the end of the module base plate 21 opposite to the second bracket 53, and the second support 73 is provided with corresponding holes for the third fixing member 74. The third fixing member 74 can be a bolt, and the module base plate 21 is locked onto the second support 73 by turning the third fixing member 74. The second support 73 and the first support 71 together realize the function of supporting the module base plate 21 and keeping the module base plate 21 balanced and stable. The second support 73 can be an inverted U-shaped structure, a rectangular structure, etc., as long as it can realize the function of supporting the module base plate 21.

[0049] Example 2 This embodiment provides a tool-free method for removing and installing an expansion card, using the tool-free expansion card removal and installation device as described in the above embodiment to remove and install the expansion card 11. The method includes: S1. Set the preset number of expansion cards 11. If the preset number is equal to 1, determine the thickness parameter of the expansion card 11 and select the slot width parameter of the support groove 41 of the support base 4 to be adapted to the thickness parameter of the expansion card 11. If the preset number is greater than 1, determine the thickness parameter of each expansion card 11 and the preset spacing of the adjacent expansion cards 11 stacked along the first direction, and adjust the slot width parameter of the multiple support grooves 41 of the support base 4 so that the slot width parameter of the multiple support grooves 41 is adapted to the thickness parameter of the multiple expansion cards 11.

[0050] For example, if only one expansion card 11 needs to be assembled, the number of support slots 41 on the support base 4 can also be one. The width of the support slot 41 is the same as the thickness of the expansion card 11 to ensure that subsequent support slots 41 can effectively support and position the expansion card 11; or, it can be ensured that one of the multiple support slots 41 is compatible with the corresponding expansion card 11. If multiple expansion cards 11 need to be assembled, the width of the support slots 41 formed between adjacent adjustment parts 42 is adapted to the thickness of the corresponding expansion card 11 by adjusting the multiple adjustment parts 42 on the support base 4.

[0051] After determining the width parameter of the support slot 41, the height parameter of the module bracket 22 along the first direction is determined according to the preset number of expansion cards 11. Specifically, the number of slots 55 on the protrusion 54 of the second bracket 53 is determined so that the number of expansion cards 11 is compatible with the number of slots 55. Then the module bracket 22 is assembled with the module base plate 21 for later use.

[0052] S2. Insert the expansion card 11 into the module bracket 22, with one end of the expansion card 11 connected to the module bracket 22.

[0053] For example, the expansion card 11 and the adapter card 12 are assembled to fit the module bracket 22. The adapter card 12 is mounted on the first bracket 51. One end of the expansion card 11 along the second direction is provided with a insert 61. The expansion card 11 is inserted into the slot of the adapter card 12 along the third direction. At the same time, the insert 61 slides along the side wall of the second bracket 53 until it is inserted into the socket 55. The end of the insert 61 away from the socket 55 abuts against the side abutment 62 of the second bracket 53.

[0054] If multiple expansion cards 11 need to be assembled, after all the inserts 61 of the multiple expansion cards 11 are installed, adjust the rotating plate 63 to cover the side rest 62 so that the rotating plate 63 presses the inserts 61 against the side rest 62. The rotating plate 63, the inserts 61 and the side rest 62 are fastened by the first fixing member 65 of the knob to achieve the stacked connection.

[0055] S3. The sliding plate 24 slides relative to the module base plate 21 from the other end of the expansion card 11 along the vertical or parallel direction of the insertion direction of the expansion card 11, gradually approaching the expansion card 11 until the support groove 41 of the support base 4 is inserted into the corresponding expansion card 11. The sliding plate 24 is connected and fixed to the module base plate 21, realizing the installation of the expansion card 11.

[0056] For example, the sliding plate 24 slides along the second direction toward the expansion card 11, and the support base 4 moves synchronously with the sliding plate 24. The edge of the expansion card 11 enters from the flared opening 43 of the support groove 41 until the support groove 41 fully supports the expansion card 11, indicating that it is inserted in place.

[0057] After the support slot 41 and the expansion card 11 are inserted into place, the sliding plate 24 and the module base plate 21 are locked by the second fixing part 27 of the knob, and the main structure is assembled to realize the installation of the expansion card 11.

[0058] S4. The main structure is installed in the chassis, the first bracket 51 is suspended on the side wall 81 of the chassis, and the module base plate 21 is supported on the first support part 71 and the second support part 73.

[0059] For example, the first bracket 51 is engaged with the mounting part 83 via a snap-fit ​​sliding connection between the suspension part 52 and the mating part 83. The first bracket 51 moves first along a first direction and then along a second direction. The suspension part 52 moves according to the trajectory of the mating part 83. When the suspension part 52 and the mating part 83 are fully engaged, the module base plate 21 abuts against the first support part 71. At the same time, the second bracket 53 abuts against the baffle 72 to form a limit. Then, the module base plate 21 and the second support part 73 are locked by the knob third fixing part 74, completing the overall installation of the disassembly and assembly device.

[0060] The expansion card 11 and the disassembly and assembly device can be positioned in the first, second, and third directions, allowing for a more rational arrangement of the internal space of the chassis. Based on the balanced positioning of the disassembly and assembly device, the positioning stability of the expansion card 11 is effectively ensured. The stable positioning of the expansion card 11 can achieve balanced load bearing, avoiding connection failure caused by unbalanced force due to the connection of the expansion card 11 to the cable.

[0061] S5. The sliding plate 24 slides from the other end of the expansion card 11 along the direction perpendicular to or parallel to the insertion direction of the expansion card 11 relative to the module base plate 21, gradually moving away from the expansion card 11 until the support groove 41 of the support base 4 separates from the corresponding expansion card 11, and disassembles the expansion card 11 from the module bracket 22.

[0062] For example, if it is necessary to disassemble the disassembly and assembly device, the third fixing member 74 is loosened to separate the module base plate 21 from the second support part 73, the suspension part 52 of the first bracket 51 is separated from the mating part 83 of the chassis side wall 81, and the main structure is taken out from the chassis; by loosening the second fixing member 27, the sliding plate 24 is gradually moved away from the expansion card 11 until the support base 4 is separated from the expansion card 11; by loosening the first fixing member 65, the rotating piece 63 is opened relative to the side rest part 62 to separate the insert 61 from the socket 55 on the second bracket 53, and at the same time the expansion card 11 is separated from the slot of the adapter card 12, so that the expansion card 11 can be disassembled from the module bracket 22.

[0063] The disassembly and assembly sequence is the reverse of the installation sequence. The disassembly and assembly device achieves guiding displacement through the cooperation of the slot structure and the I-beam, locks and fixes the position through the knob bolt, and positions it through plug-in and crimping. This allows for tool-free assembly of the expansion card into the chassis, resulting in high efficiency.
