Description
Technical Field
[0001] This application relates to the field of electronic equipment technology, and more particularly to devices with extended functions and electronic equipment. Background Technology
[0002] With the rapid development of internet technology, server systems have placed higher demands on architectural flexibility and functional scalability. Although using a modular chassis structure to accommodate expansion cards can effectively reduce maintenance difficulty and installation costs, the industry has standardized requirements for the overall size of server units. The front panel area must be densely integrated with various types of functional modules within a limited space. However, in designs that need to support eight single-width expansion cards, the front panel space is already saturated, making it difficult to accommodate two horizontally arranged storage hard drive modules or widened network expansion cards, thus limiting the overall configuration flexibility of the system. Summary of the Invention
[0003] This application provides an expansion function device and electronic device to at least solve the problem in the related art where the server front window space is limited, making it difficult to simultaneously accommodate multiple expansion cards and two horizontally arranged storage hard disk modules or widened network expansion cards.
[0004] This application provides an expansion function device, including an expansion card and an adapter board. The adapter board includes a mating connector and a power connector, with the mating connector connected to the expansion card. The expansion function device includes a mounting frame, which has a card slot and a clearance opening. The adapter board is mounted on the mounting frame. The mating connector is located on the side of the adapter board facing the mounting frame and corresponds to the position of the card slot. The power connector is located on the side of the adapter board facing the mounting frame and corresponds to the position of the clearance opening. The wire exit surface of the adapter board is located on the side of the adapter board facing away from the mounting frame.
[0005] This application also provides an electronic device, including a chassis and the aforementioned extended function device, wherein the extended function device is disposed within the chassis.
[0006] This application places the wider power connector on the inner side of the adapter board facing the mounting frame, with a corresponding clearance opening on the mounting frame to accommodate it. Simultaneously, the cable exit surface is located on the outer side of the adapter board, facing away from the mounting frame. This fully utilizes the internal space of the mounting frame, resolving the issue of the power connector encroaching on the adapter board's width and relocating the cable exit surface to open external space, ensuring smooth cable routing. Through this rational replacement of the inner and outer mounting spaces, the overall width of the expansion device is reduced. This allows the overall structure to accommodate expansion cards while also supporting the installation of two horizontally arranged storage hard drive modules and several horizontally arranged widened network expansion cards, thereby improving the internal space utilization of the chassis and meeting the design requirements of width constraints. Therefore, it solves the problem of limited front window space in servers, making it difficult to simultaneously accommodate multiple expansion cards and two horizontally arranged storage hard drive modules or widened network expansion cards.

[0012] 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.
[0013] The embodiments of this application provide an extended function device 1 and an electronic device. The device is described in detail below in conjunction with the structure and working principle of the extended function device 1 and the electronic device.
[0014] According to an embodiment of the present invention, in one aspect, an expansion function device 1 is provided, including an expansion card 11 and an adapter board 12. The adapter board 12 includes a mating connector 121 and a power connector 122, and the mating connector 121 is connected to the expansion card 11; as Figure 7 , Figure 11 and Figure 12As shown, the extended function device 1 includes a mounting frame 13, which has a slot 13111 and a clearance slot 13112; an adapter plate 12 is mounted on the mounting frame 13, a mating connector 121 is located on the side of the adapter plate 12 facing the mounting frame 13 and corresponds to the position of the slot 13111; a power connector 122 is located on the side of the adapter plate 12 facing the mounting frame 13 and corresponds to the position of the clearance slot 13112; and the wire bonding surface 123 of the adapter plate 12 is located on the side of the adapter plate 12 facing away from the mounting frame 13.
[0015] In the above embodiments, this application places the wider power connector 122 on the inner side of the adapter plate 12 facing the mounting frame 13, and provides clearance 13112 on the mounting frame 13 to accommodate it. Simultaneously, the wire exit surface 123 is located on the outer side of the adapter plate 12 facing away from the mounting frame 13. This fully utilizes the internal space of the mounting frame 13 for clearance, solving the problem of the power connector 122 encroaching on the width of the adapter plate 12, and relocating the wire exit surface 123 to an open external space, ensuring smooth cable routing. Through the reasonable replacement of the inner and outer mounting spaces 4, the overall width of the expansion device 1 is reduced, allowing the overall structure to meet the assembly requirements of the expansion card 11 while also accommodating the installation requirements of two horizontally arranged storage hard disk modules and several horizontally arranged widened network expansion cards 11. This improves the internal space utilization of the chassis 2 and meets the design requirements limited by width. Therefore, it can solve the problem that the limited front window space of the server makes it difficult to simultaneously accommodate multiple expansion cards 11 and two horizontally arranged storage hard disk modules or widened network expansion cards 11.
[0016] In specific implementation methods, such as Figure 7 and Figure 8 As shown, the expansion device 1 is compatible with four expansion cards 11, which are stacked vertically. Correspondingly, the expansion device 1 includes two adapter plates 12, each equipped with two mating connectors 121, allowing each adapter plate 12 to connect to two expansion cards 11 respectively. Simultaneously, the card slots 13111 on the mounting frame 13 correspond one-to-one with the positions of the expansion cards 11, ensuring that each expansion card 11 can be accurately inserted into its corresponding position, thereby achieving reliable electrical connection and structural fixation.
[0017] In a specific implementation, the slot 13111 serves as the extension channel and positioning reference for the mating connector 121. After the adapter plate 12 is installed in place, the mating connector 121 extends through the slot 13111 from the side of the first frame 131. The edge contour of the slot 13111 provides limiting constraints on the extension direction and position of the connector, ensuring that the connector slot and the gold fingers of the expansion card 11 maintain precise alignment during mating, thereby achieving reliable electrical connection and mechanical engagement.
[0018] Specifically, the opening size of the card slot 13111 can be set according to actual needs, so that it can be compatible with two different structural forms of expansion card 11, with and without card hooks, avoiding the need to replace the mounting frame 13 or perform secondary processing due to the difference in expansion card 11 type, thus improving the versatility of the mounting frame 13.
[0019] Preferably, the original overall cable structure, which consisted of multiple thin cables bundled into a circular bundle, is changed to a fan-shaped cable layout arranged in a flat manner. This makes the cables flat and effectively reduces the size of the wire exit point protruding from the adapter plate 12, meeting the assembly requirements within a limited space. Under the premise of ensuring the reliability of the cable connection, the size of the exit area is reduced.
[0020] In this embodiment, the power connector 122 is positioned on the side of the adapter plate 12 facing the mounting frame 13, while the wire outlet surface 123 of the adapter plate 12 is positioned on the side of the adapter plate 12 facing away from the mounting frame 13. The multiple thin cables connected to the adapter plate 12 are arranged in a fan-shaped, laid-out manner. This optimized cable management effectively saves space in the width direction of the expansion device 1, allowing the overall structure to accommodate the installation requirements of two horizontally arranged storage hard disk modules and several horizontally arranged widened network expansion cards 11, thereby improving the internal space utilization of the chassis 2.
[0021] In one embodiment, such as Figure 9 and Figure 10 As shown, the mounting frame 13 includes a first frame 131, which includes a first sub-frame 1311 and a second sub-frame 1312. The slot 13111 and the clearance slot 13112 are both provided on the first sub-frame 1311. The second sub-frame 1312 is detachably connected to the tail of the first sub-frame 1311.
[0022] In the above embodiment, by configuring the first frame 131 of the mounting frame 13 as a structure in which the first sub-frame 1311 and the second sub-frame 1312 are detachably connected, the second sub-frame 1312, as a tail support, can be flexibly assembled or disassembled according to actual needs. When it is necessary to adapt to a full-length expansion card 11, the second sub-frame 1312 is installed to provide reliable tail support; when adapting to a half-length expansion card 11, the tail support can be disassembled or omitted, thereby making it compatible with expansion cards 11 of different specifications on the same mounting frame 13. This not only avoids developing dedicated frames for expansion cards 11 of different lengths, reducing manufacturing costs, but also improves the flexibility and adaptability of assembly.
[0023] In specific implementation methods, such as Figure 7 and Figure 8 As shown, the first sub-frame 1311 has a stepped positioning post 13113 protruding from the side near the adapter plate 12. The adapter plate 12 has a corresponding connection hole 124. Screws and other fasteners pass through the connection hole 124 and connect to the corresponding stepped positioning post 13113. The number of stepped positioning posts 13113 can be set according to actual needs, for example, three, four, five or more can be provided, and there is no specific limitation here. After the adapter plate 12 is installed, each expansion card 11 is pushed into the designated position in sequence according to the corresponding card slot 13111 on the mounting frame 13, so that the gold fingers of the expansion card 11 are aligned with the slot of the mating connector 121 on the adapter plate 12 until it is inserted into place. Then, screws and other fasteners are used to fix the expansion card 11 on the side.
[0024] Preferably, such as Figure 8 and Figure 9 As shown, the power connector 122 is located at the end of the adapter plate 12 near the second sub-frame 1312, i.e., at the end of the adapter plate 12. Correspondingly, the clearance opening 13112 on the first sub-frame 1311 is located at the end of the first sub-frame 1311 near the second sub-frame 1312, and the end of the clearance opening 13112 facing the second sub-frame 1312 is an open structure. Under normal operating conditions, the second sub-frame 1312 is installed at the tail of the first sub-frame 1311, and the open structure of the clearance opening 13112 is blocked by the second sub-frame 1312, thus forming a completely closed clearance opening 13112 structure, which satisfies the clearance requirement of the power connector 122 in the width direction, and maintains the overall sealing and integrity of the side of the mounting frame 13. When it is necessary to perform terminal plugging and unplugging maintenance on the power connector 122, the second sub-frame 1312 is removed from the first sub-frame 1311, exposing the open structure of the port 13112 near the end of the second sub-frame 1312, so that the plugging and unplugging area where the power connector 122 is located is fully exposed. The operator can directly plug and unplug the power connector 122 through the open structure without removing the adapter plate 12 or other components.
[0025] By setting the clearance port 13112 as an open end and combining it with the second sub-frame 1312 as its removable sealing component, the same clearance port 13112 structure can serve both clearance and sealing functions under normal use, and transform into an operation window under maintenance. This avoids the increased parts cost and assembly process of separately opening a removable cover for the power connector 122, and also eliminates the need to increase the overall width of the machine to reserve extra operating space for plugging and unplugging operations. While ensuring the compactness of the overall structure, it improves the maintainability and convenience of plugging and unplugging operations of the power connector 122.
[0026] In one embodiment, such as Figure 9 and Figure 10 As shown, the first sub-frame 1311 and the second sub-frame 1312 are connected by a first connecting structure. The first connecting structure includes a first stop portion, a first connecting portion 142, and a second connecting portion 143. The first stop portion includes a first stop groove 1411 and a first stop member 1412 that cooperate with each other. One of the first stop groove 1411 and the first stop member 1412 is provided in the first sub-frame 1311, and the other is provided in the second sub-frame 1312. The first connecting portion 142 connects the top of the first sub-frame 1311 and the top of the second sub-frame 1312. The second connecting portion 143 connects the bottom of the first sub-frame 1311 and the bottom of the second sub-frame 1312.
[0027] In the above embodiment, by setting a first stop portion, the connection and positioning between the first sub-frame 1311 and the second sub-frame 1312 are achieved through the mutual cooperation of the first stop groove 1411 and the first stop member 1412; at the same time, the first connecting portion 142 and the second connecting portion 143 respectively provide bidirectional connection and fixation between the first sub-frame 1311 and the second sub-frame 1312 from the top and bottom, ensuring reliable splicing of the first sub-frame 1311 and the second sub-frame 1312. This ensures that the first frame 131 has sufficient overall rigidity and load-bearing capacity, ensuring the stability and reliability of the expansion card 11 in the working state, and avoiding problems such as loose connection or card body displacement caused by insecure fixing or insufficient strength.
[0028] In one embodiment of this example, a first stop groove 1411 is provided on a first sub-frame 1311, and a first stop member 1412 is provided on a second sub-frame 1312.
[0029] In another embodiment of this invention, the first stop member 1412 is provided on the first sub-frame 1311, and the first stop groove 1411 is provided on the second sub-frame 1312.
[0030] In this embodiment, the first stop member 1412 includes a first I-beam nail, which protrudes from the bottom of the second sub-frame 1312; the first stop groove 1411 is a first sliding groove that cooperates with the first I-beam nail, and is located at the bottom of the first sub-frame 1311. When the first sub-frame 1311 and the second sub-frame 1312 are assembled, the first I-beam nail and the first sliding groove are slidably engaged for positioning.
[0031] In this embodiment, the first connecting part 142 includes fasteners such as screws. After the first stop member 1412 and the first stop groove 1411 are slidably engaged, the first connecting part 142 connects the top of the first sub-frame 1311 and the top of the second sub-frame 1312. The number of first connecting parts 142 is not limited; there may be two, three, or more first connecting parts 142.
[0032] In this embodiment, the second connecting part 143 includes fasteners such as screws. After the first stop member 1412 and the first stop groove 1411 are slidably engaged, the second connecting part 143 connects the bottom of the first sub-frame 1311 and the bottom of the second sub-frame 1312. The number of second connecting parts 143 is not limited, and the first connecting part 142 may have two, three, or more components.
[0033] In one embodiment, such as Figure 10 As shown, the first frame 131 also includes a cable management clip 1313, which is disposed on the second sub-frame 1312. The cable management clip 1313 includes a fixing part 13131, a snap-fit part 13132, and a clamping part 13133. The fixing part 13131 is fixed to the second sub-frame 1312. The snap-fit part 13132 is fixed to the second sub-frame 1312 and is spaced apart from the fixing part 13131. The clamping part 13133 is spaced apart from the second sub-frame 1312, with one end rotatably connected to the fixing part 13131 and the other end snapped into the snap-fit part 13132. The second sub-frame 1312, the fixing part 13131, the snap-fit part 13132, and the clamping part 13133 together form a cable management hole.
[0034] In the above embodiment, by fixing the fixing part 13131 to the second sub-frame 1312, and using the snap-fit part 13132 and the rotatable clamping part 13133 to cooperate, together with the second sub-frame 1312, a cable management hole is formed. This cable management hole can effectively gather and tighten the cables leading out from the wire outlet surface 123 of the adapter plate 12 and the power connector 122. While ensuring that the cable management clamp 1313 has sufficient structural strength, the cables are neatly gathered, avoiding the loosening of connections that may be caused by scattered or shaking cables, thus ensuring the cleanliness of the internal wiring of the entire machine.
[0035] In this embodiment, two cable management clips 1313 are provided, arranged sequentially along the vertical direction of the mounting frame 13. Each clip corresponds one-to-one with one adapter plate 12, meaning each clip is used to gather and tighten the cables extending from the soldering wire exit surface 123 and power connector 122 of that adapter plate 12. This layered arrangement of the two clips 1313 allows for independent organization and restraint of the cables connected to each adapter plate 12 by its corresponding clip, preventing cables from crossing or tangling between different adapter plates 12 and improving the neatness and identifiability of the wiring. Furthermore, the layered arrangement of the two clips 1313 fully utilizes the vertical height of the mounting frame 13, avoiding additional space occupation in the width direction of the chassis 2 and contributing to the compactness of the overall structure. When it is necessary to maintain the cables on a certain layer of the adapter board 12, only the corresponding cable management clip 1313 needs to be operated separately, without disturbing the cable management clip 1313 and its cables on another layer, thereby improving the overall assembly efficiency and maintenance convenience.
[0036] In one embodiment, such as Figure 4 , Figure 5 , Figure 6 and Figure 13 As shown, the mounting frame 13 also includes a second frame 132, which is detachably connected to the first frame 131. The second frame 132 includes a base plate 1321 and a first side plate 1322. The first side plate 1322 is connected to one side of the base plate 1321. The first frame 131, the base plate 1321 and the first side plate 1322 form a first accommodating space, which is used to accommodate the expansion card 11.
[0037] In the above embodiment, by providing a second frame 132 detachably connected to the first frame 131, and having the first frame 131, base plate 1321, and first side plate 1322 together form a first accommodating space for accommodating the expansion card 11, independent protection for the expansion card 11 is formed. Simultaneously, the detachable structure of the second frame 132 facilitates disassembly and maintenance of the expansion card 11, and also allows for flexible assembly or replacement according to the actual size of the expansion card 11. While ensuring structural stability, it also considers the compatibility requirements of different card specifications, enhancing the overall frame's versatility and facilitating the disassembly and maintenance of the expansion card 11.
[0038] In one embodiment, the second frame 132 further includes a second side plate 1323, which is connected to the side of the bottom plate 1321 opposite to the first side plate 1322; the first frame 131 includes a support plate 1314 and a top plate 1315, which is connected to the top of the support plate 1314, and the slot 13111 and the clearance slot 13112 are both provided on the support plate 1314; the support plate 1314 and the second side plate 1323 are opposite to each other and spaced apart, and the top plate 1315, the bottom plate 1321, the support plate 1314 and the second side plate 1323 enclose a second accommodating space, and the adapter plate 12 and the cable clip 1313 are both located in the second accommodating space.
[0039] In the above embodiment, the top plate 1315, bottom plate 1321, support plate 1314, and second side plate 1323 together enclose a second accommodating space, which accommodates both the adapter plate 12 and the cable management clip 1313. Based on the already formed first accommodating space, an independent second accommodating space is further expanded, realizing a partitioned layout of the expansion card 11, adapter plate 12, and cable management clip 1313, effectively avoiding spatial interference between functional components. Simultaneously, the four-sided enclosed structure formed by the top plate 1315, bottom plate 1321, support plate 1314, and second side plate 1323 provides protection for the internal adapter plate 12 and cables, and ensures that the cables leading from the adapter plate 12 are routed orderly within the defined channel between the support plate 1314 and the second side plate 1323, preventing exposed or loose cables and improving the compactness of the overall internal layout and the neatness of the wiring.
[0040] In a specific embodiment, the second frame 132 is provided with a base plate 1321 and a first side plate 1322 and a second side plate 1323 respectively connected to both sides of the base plate 1321. The first side plate 1322 and the second side plate 1323 form an installation space 4 that is adapted to the width of the first frame 131. When the first frame 131 is installed on the second frame 132, the first side plate 1322 and the second side plate 1323 not only play a guiding and positioning role when the first frame 131 is installed, but also limit and constrain it in the width direction from both sides of the first frame 131, thereby limiting the first frame 131 to a predetermined installation position.
[0041] Preferably, both the first side plate 1322 and the second side plate 1323 are provided with a double-layer support structure, and the inner wall of the double-layer support structure limits the width of both sides of the first frame 131.
[0042] Specifically, the double-layer support structure is formed by bending and folding or adding reinforcing plates to a portion of the material of the first side plate 1322 or the second side plate 1323, so that the thickness of this portion in the width direction is greater than the single-layer thickness of the side plate body 13221, thereby creating a narrower limiting gap between the first side plate 1322 and the second side plate 1323 compared to other areas. When the first frame 131 is installed into the second frame 132 along the installation direction, the double-layer support structure fills the assembly gap between the first frame 131 and the first side plate 1322 and the second side plate 1323 to a minimum, limiting the movement allowance of the first frame 131 in the width direction to a preset allowable range. At the same time, the double-layer support structure has higher bending stiffness, and even if the first frame 131 is subjected to lateral pushing force during installation or vibration impact during operation, it is not easy to deform.
[0043] In specific implementation methods, such as Figure 7 As shown, during the installation of the expansion card 11 without a protective casing, to prevent its surface from colliding with the iron structure above the first frame 131, the top plate 1315 is provided with a clearance opening 13151 at the corresponding position of the first receiving space. The clearance opening 13151 provides clearance space for protruding components on the surface of the expansion card 11 when it is pushed in, preventing physical interference with the iron structure above the first frame 131, thus avoiding damage to the components due to collision and ensuring that the expansion card 11 can be smoothly pushed in and accurately positioned.

[0055] According to an embodiment of the present invention, another aspect provides an electronic device, including a chassis 2 and the aforementioned extended function device 1, wherein the extended function device 1 is disposed within the chassis 2.
[0056] It should be noted that the electronic device in this embodiment is a server. In other embodiments of the present invention, the electronic device may also be a switching device, a storage device, a power device, a computer, or other electronic devices.
[0057] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the chassis 2 is provided with a partition 3, which divides the internal space of the chassis 2 into multiple installation spaces 4, and the expansion function device 1 is inserted into any of the installation spaces 4.
[0058] In the above embodiment, by setting a partition plate 3 inside the chassis 2, the internal space of the chassis 2 is divided into multiple independent installation spaces 4, and the expansion function device 1 is inserted into the corresponding installation space 4, realizing the partitioned installation and independent management of the expansion function device 1. This ensures that each expansion function device 1 has an independent installation space 4, avoiding physical interference between different devices, and facilitating independent insertion, removal, and maintenance of individual expansion function devices 1 without affecting devices in other installation spaces 4. Simultaneously, the installation space 4 can effectively limit and support the inserted expansion function device 1, enhancing the installation stability of the expansion function device 1 under vibration or shock environments; furthermore, the partition plate 3 also provides a certain degree of electromagnetic shielding and thermal isolation, reducing electromagnetic interference and thermal impact between adjacent functional devices, and ensuring the reliability and stability when multiple devices operate in parallel.
[0059] In a specific implementation, multiple partition plates 3 are provided, all located in the front window area of the chassis 2. These partition plates 3 are spaced apart sequentially along the width of the chassis 2, dividing the front window area into multiple independent installation spaces 4 arranged along the width direction. Each installation space 4 has an installation opening at the front window of the chassis 2. The expansion function device 1 is inserted into and fixed within the installation space 4 via the installation opening using a pull-out method. Only one set of expansion function devices 1 can be accommodated in each installation space 4.
[0060] For example, two partitions are spaced apart to divide the internal space of the front window area of the chassis 2 into three installation spaces 4 as interchangeable module sections. The installation spaces 4 on both sides are used to insert the expansion function device 1 of this application. The expansion function device 1 adopts an interchangeable installation method and can be directly pushed into the chassis 2 from the front window direction, thereby realizing convenient installation and removal operations. The installation space 4 in the middle can install two horizontally arranged storage hard disk modules or widened network expansion cards 11.
[0061] In one embodiment, the extended function device 1 and the chassis 2 are connected by a third connection structure, which includes a third stop portion 51 and a fourth connection portion 52. The third stop portion 51 includes a third stop groove 511 and a third stop member 512 that cooperate with each other. One of the third stop groove 511 and the third stop member 512 is provided in the extended function device 1, and the other is provided in the chassis 2. The fourth connection portion 52 connects the extended function device 1 and the chassis 2.
[0062] In the above embodiment, by providing a third stop portion 51, and utilizing the cooperation of the third stop groove 511 and the third stop member 512, the expansion function device 1 and the chassis 2 are installed and positioned during assembly; the fourth connecting portion 52 connects and fixes the expansion function device 1 and the chassis 2, ensuring reliable splicing of the expansion function device 1 and the chassis 2. Through the provision of the third stop portion 51 and the fourth connecting portion 52, the expansion function device 1 and the chassis 2 can achieve both detachable and flexible assembly, facilitating replacement or maintenance according to different expansion card 11 specifications, and ensuring positional accuracy and structural stability after connection, avoiding relative displacement caused by assembly errors or vibration impacts, thereby ensuring the stability of the expansion function device 1 in the working state.
[0063] In one embodiment of this invention, the third stop groove 511 is provided in the extended function device 1, and the third stop member 512 is provided in the chassis 2.
[0064] In another embodiment of this invention, the third stop member 512 is provided on the extended function device 1, and the third stop groove 511 is provided on the chassis 2.
[0065] In this embodiment, the third stop member 512 includes a third I-beam nail, which protrudes from the base of the chassis 2; the third stop groove 511 is a third sliding groove that cooperates with the third I-beam nail, and is located at the tail of the bottom plate 1321 of the mounting frame 13. When the extended function device 1 is inserted into the designated position, the third I-beam nail and the third sliding groove slide to be positioned.
[0066] For example, at least two sets of third stop portions 51 are provided at intervals along the width direction of the extended functional device 1.
[0067] In a specific implementation, the fourth connecting part 52 includes a hand-turning screw. After the third stop member 512 and the third stop groove 511 are slidably engaged, the fourth connecting part 52 connects the tail of the base plate 1321 of the mounting frame 13 and the base of the chassis 2.
[0068] In this embodiment, the fourth connecting part 52 also includes fasteners such as screws to fix the upper cover of the front window of the chassis 2 and the extended function device 1.
[0069] For example, at least two sets of fourth connecting portions 52 are provided at intervals along the width direction of the extended functional device 1.
[0070] Specifically, during installation, the tail of the first sub-frame 1311 is first aligned with the head of the second sub-frame 1312, so that the first stop groove 1411 and the first stop member 1412 respectively provided on the first sub-frame 1311 and the second sub-frame 1312 cooperate with each other. The installation and positioning of the first sub-frame 1311 and the second sub-frame 1312 are achieved through the cooperation of the first stop groove 1411 and the first stop member 1412. Then, the top of the first sub-frame 1311 is fixedly connected to the top of the second sub-frame 1312 through the first connecting part 142, and the bottom of the first sub-frame 1311 is fixedly connected to the bottom of the second sub-frame 1312 through the second connecting part 143.
[0071] Then, the cable connected to the power connector 122 on the adapter plate 12 is pre-connected, and the mating connector 121 on the adapter plate 12 is aligned with the corresponding slot 13111 on the first sub-frame 1311, so that the mating connector 121 extends from the slot 13111 to the outside of the first sub-frame 1311 for subsequent mating with the gold fingers of the expansion card 11. Next, the protruding stepped positioning post 13113 on the first sub-frame 1311 is aligned with the corresponding connection hole 124 on the adapter plate 12, and the adapter plate 12 is secured to the stepped positioning post 13113 using screws or other fasteners, thus connecting the adapter plate 12 to the first sub-frame 1311. At this time, the wire exit surface 123 of the adapter plate 12 faces the side of the first sub-frame 1311 away from the mounting frame 13, i.e., the wire exit surface 123 is located on the outer side of the adapter plate 12, facilitating cable routing. Then, the cables leading out from the wire outlet surface 123 of the adapter board 12 and the power connector 122 are respectively placed into the corresponding cable clips 1313, thereby completing the installation of the adapter board 12 and the arrangement of the cables.
[0072] After completing the installation of the adapter board 12 and the cable, begin installing the expansion card 11. Align the gold fingers of the expansion card 11 with the slot of the connector 121 on the adapter board 12, which has extended from the card slot 13111. Then, push the expansion card 11 into the connector 121 from the side, ensuring that the gold fingers of the expansion card 11 are fully inserted into the slot of the connector, thus establishing an electrical connection between the expansion card 11 and the adapter board 12. After the expansion card 11 is in place, use screws or other fasteners to pass through the fixing holes on the expansion card 11 and lock them into the corresponding screw holes 13114 on the first sub-frame 1311, thereby fixing the expansion card 11 to the first sub-frame 1311 and providing reliable support for the expansion card 11 in the plugged-in state.
[0073] In a specific embodiment, the upper-level overall structure, consisting of the first frame 131 after the adapter board 12, cables, and expansion card 11 are installed, is inserted into the second frame 132 from top to bottom. During the installation process, the second I-beam 1513 on the top of the second sub-frame 1312 cooperates with the second sliding groove 1511 on the second frame 132, and the stop pin 1514 on the top of the first sub-frame 1311 cooperates with the guide groove 1512 on the second frame 132. By sliding the second I-beam 1513 along the second sliding groove 1511 and the stop pin 1514 along the guide groove 1512, the upper-level structure is guided to descend smoothly in a predetermined direction, thereby achieving guidance and constraint on the installation trajectory. When the upper structure descends to near the final installation position, the positioning pin 1521 on the second frame 132 aligns with and is inserted into the positioning hole 1522 on the positioning plate 13121 at the tail of the second sub-frame 1312. The positioning pin 1521 and the positioning hole 1522 work together to achieve the final positioning of the upper structure in the horizontal plane, ensuring that each connection point is accurately aligned.
[0074] After the upper-level overall structure is installed in place, the tail of the second sub-frame 1312 is fixedly connected to the base plate 1321 of the second frame 132 through the third connecting part 153. At the same time, the first sub-frame 1311 is fixedly connected to the second side plate 1323 of the second frame 132. The upper-level overall structure and the second frame 132 are fastened together by multi-point locking, thereby completing the assembly of the entire extended functional device 1.
[0075] In a specific embodiment, the expansion device 1 is pushed horizontally from front to back into the installation space 4 separated by the partition through the mounting opening at the front window of the chassis 2. During the process of the expansion device 1 moving along the insertion direction to the predetermined installation position, the third stop groove 511 provided on the expansion device 1 cooperates with the third stop member 512 on the base of the chassis 2. The stop member 512, after entering the third stop groove 511, forms a restraint, limiting the endpoint of the insertion stroke of the expansion device 1 to prevent over-insertion or improper installation, while simultaneously achieving the predetermined positioning of the expansion device 1 within the installation space 4. After the expansion device 1 reaches the predetermined installation position, the fourth connecting part 52 securely connects the expansion device 1 to the chassis 2, ensuring a tight connection between the expansion device 1 and the chassis 2.
[0076] The above provides a detailed description of the extended functionality device 1 and electronic device provided in this application. 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. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
