Description

Technical Field

[0001] This application relates to the field of computer accessories technology, and more particularly to a graphics card mounting device and a server. Background Technology

[0002] In the server industry, a graphics card (GPU) is connected to the motherboard on one end and is free on the other. For graphics cards that are long or heavy, an additional support device is needed at the rear end to prevent the graphics card from sagging or wobbling.

[0003] Currently, most servers use a single sheet metal fastener to fix the graphics card at the rear. When installing graphics cards of different lengths, new support and fixing devices need to be redesigned and developed.

[0004] To address this issue, adjustable-length support devices have emerged in related technologies, offering multiple extension length options. However, when the graphics card's length does not precisely match any of these options, the support device cannot securely hold the graphics card in place, potentially leading to unstable support, poor contact, or even damage at the rear of the graphics card. Summary of the Invention

[0005] This application discloses a graphics card installation device and a server, which can achieve stepless adjustment of the total length of the graphics card installation device through the cooperation of a large-range coarse adjustment of the gear component and a small-range fine adjustment of the adjustment component, thereby adapting to graphics cards of different lengths and sizes and improving the practicality of the graphics card installation device.

[0006] In a first aspect, embodiments of this application provide a graphics card mounting device, comprising: a bracket fixing member for connecting to a graphics card; a bracket moving member movably connected to the bracket fixing member, the bracket moving member being movable relative to the bracket fixing member along a first direction; a stop assembly disposed on the bracket moving member and the bracket fixing member, the stop assembly being used to lock the bracket moving member in multiple target stops, wherein the distance between the bracket moving member and the bracket fixing member along the first direction is unequal when the bracket moving member is in different target stops; and an adjusting member movably disposed on the bracket moving member, the adjusting member being used to fix the bracket moving member to an external component, the adjusting member being movable relative to the bracket moving member along the first direction and locked to the external component; the adjusting member being used to compensate for the gap between the bracket moving member and the external component along the first direction when the bracket moving member is in any of the target stops.

[0007] Thus, the graphics card installation device provided in this application embodiment achieves a wide range of coarse adjustments through the gear assembly and a small range of continuous fine adjustments through the adjusting component. The combination of these two features enables stepless adjustment of the total length of the graphics card installation device, accommodating graphics cards of different lengths and sizes. This improves the reusability of the graphics card installation device and reduces development cycle and cost. The bracket fixing component can be connected to the graphics card using hand-tightened screws, and the adjusting component can be secured to external components using hand-tightening locking mechanisms. Operators can complete installation and disassembly without the need for screwdrivers or other tools. This tool-free design simplifies the operation process and shortens the installation and maintenance time of the graphics card.

[0008] In one possible implementation, the gear shift component has a locked state and an unlocked state, and the graphics card mounting device further includes: a first elastic element disposed between the bracket fixing member and the bracket moving member; when the gear shift component switches from the locked state to the unlocked state, the first elastic element drives the bracket moving member to move relative to the bracket fixing member until the bracket moving member abuts against the external component; after the bracket moving member abuts against the external component, the gear shift component can be controllably switched to the locked state to lock the bracket moving member at the current target gear shift.

[0009] Thus, the graphics card mounting device provided in this embodiment, through the setting of the first elastic element, allows the bracket moving part to automatically extend until it abuts against the external component after unlocking. This eliminates the need for operators to pre-measure the distance from the graphics card's tail end to the crossbeam outside the chassis, and also eliminates the need to manually pull out the bracket moving part and perform repeated trial installations. The entire length adaptation process is automatically completed inside the chassis, simplifying the installation operation and improving assembly efficiency. Furthermore, the locking assembly locks the bracket moving part at the current target position after it abuts against the external component, ensuring the length stability of the graphics card mounting device before locking and providing a reliable positional reference for subsequent locking operations of the adjustment components.

[0010] In one possible implementation, the gear shift assembly includes: a latching member disposed on the movable member of the bracket, the latching member having a plurality of spaced-apart slots along the first direction, the plurality of slots corresponding to the plurality of target gear shifts; a locking member movably connected to the fixed member of the bracket and movable between a locked position and a released position; a second elastic member connected to the fixed member of the bracket and the locking member, for driving the locking member to reset from the released position to the locked position; when the locking member is in the released position, the locking member disengages from the latching member to allow the movable member of the bracket to move relative to the fixed member to different target gear shifts; when the locking member returns to the locked position, the locking member engages with one of the slots of the latching member to lock the movable member of the bracket relative to the fixed member to the current target gear shift.

[0011] Thus, the mounting components, including a latching element, a locking element, and a second elastic element, utilize multiple spaced slots on the latching element to engage with the movable locking element, allowing the movable bracket to be selectively fixed at different distances from the fixed bracket. This enables the same graphics card mounting device to accommodate various graphics cards of different lengths, eliminating the need for developing dedicated fixing devices for each type of graphics card. Furthermore, the second elastic element provides an automatic reset function for the locking element. The operator only needs to manually pull the locking element to move it from the locked position to the released position, at which point the movable bracket can freely adjust the distance between itself and the fixed bracket. After adjustment, the operator simply releases the locking element, which automatically resets to the locked position under the drive of the second elastic element and engages with the corresponding slot. The entire adjustment process requires no tools; the operator can complete the gear switching and locking manually, achieving truly tool-free installation and significantly improving the convenience of graphics card installation and replacement.

[0012] In one possible implementation, the locking member is movable along a second direction, which intersects with the first direction, and the locked position and the released position are arranged along the second direction. The locking member has an engaging hole comprising a first segment and a second segment arranged along the second direction and communicating with each other. The diameter of the second segment is larger than the diameter of the engaging member, and the diameter of the first segment is smaller than the diameter of the engaging member. When the locking member is in the released position, the second segment corresponds to the engaging member along the first direction, allowing the engaging member to move relative to the locking member along the first direction. When the bracket moving member moves to abut against the external component, the locking member can be controllably reset from the released position to the locked position, the first segment corresponds to the engaging member along the first direction, and allows a slot on the engaging member to enter the first segment and engage with it.

[0013] Thus, by using the difference in diameter between the first and second segments of the locking hole on the locking component, reliable switching between the locked and unlocked states between the locking component and the latching component is achieved. When the locking component is in the released position, the larger-diameter second segment aligns with the latching component, providing space for the latching component to move, allowing the bracket moving component to be smoothly adjusted in the first direction, thereby realizing the length adjustment of the graphics card mounting device. When the locking component is reset to the locked position, the smaller-diameter first segment engages with the latching component, forming a reliable lock with the slot on the latching component. This structural design requires no tools; the operator only needs to overcome the elastic force of the second elastic element to move the locking component to switch between locking and unlocking, making the entire operation quick and reliable.

[0014] In one possible implementation, the locking member is provided with a first guide hole extending along the second direction, the first guide hole having a first end and a second end opposite to each other along the second direction; the gear assembly further includes a guide member disposed on the bracket fixing member, the guide member passing through the first guide hole; when the locking member is in the released position, the guide member abuts against the first end of the first guide hole; when the locking member is reset to the locked position, the guide member abuts against the second end of the first guide hole.

[0015] Thus, the precise control of the locking member's movement stroke is achieved through the cooperation of the guide member and the first guide hole. The contact between the guide member and the first end of the first guide hole defines the locking position, ensuring accurate alignment of the first hole segment with the locking member at this time; the contact between the guide member and the second end of the first guide hole defines the release position, ensuring accurate alignment of the second hole segment with the locking member at this time. This eliminates the need for operators to rely on feel to determine whether the locking member has moved into position; simply pulling or releasing the locking member ensures accurate alignment of the corresponding hole segment with the locking member, reducing the operational difficulty and the skill requirements for operators.

[0016] In one possible implementation, the movable support member has a groove extending along the first direction, the adjusting member is movably inserted into the groove, and the adjusting member can be fixed relative to the movable support member at multiple consecutive positions along the first direction in the groove and locked with the external component.

[0017] Thus, the graphics card mounting device provided in this application embodiment, through the cooperation of the sliding groove on the bracket moving part and the adjusting part, allows the adjusting part to move continuously along the first direction within the sliding groove and to be fixed at any position, providing flexible micro-adjustment capability and eliminating installation length deviation caused by the distance between target levels. The adjusting part serves both to lock the bracket moving part to the external component and to perform micro-compensation adjustment, offering multiple functions and simplifying the structure of the graphics card mounting device. The adjusting part can be in the form of a hand-tightening screw, allowing operators to complete the movement, positioning, and locking operations of the adjusting part without the need for any tools. The adjusting part can be fixed at any position within the sliding groove, enabling the graphics card mounting device of this application embodiment to adapt to graphics cards of any length, rather than being limited to the installation distance corresponding to a few target levels, thus improving the versatility and adaptation accuracy of the graphics card mounting device.

[0018] In one possible implementation, the movable support member and the fixed support member are detachably connected via a connector.

[0019] In this way, the connecting parts enable a detachable connection between the movable and fixed bracket components. The same fixed bracket component can be used with various movable bracket components of different specifications, forming modular designs. The fixed and movable bracket components can be designed separately according to actual needs, thus covering the installation requirements of graphics cards of different lengths, weights, and models, reducing the complexity of graphics card installation device development. The detachable connection gives the graphics card installation device excellent scalability and maintainability. When the server is upgraded to use a new model of graphics card, it is not necessary to replace the entire device; only the movable bracket component of the corresponding specification needs to be replaced. When a component wears out, only the damaged component needs to be replaced, without scrapping the entire graphics card installation device.

[0020] In one possible implementation, the bracket fixing member further includes a second guide hole, through which the connector passes and is connected to the bracket moving member; the second guide hole has a preset length along the first direction, and is used to guide the movement of the bracket moving member and limit the travel distance of the bracket moving member relative to the bracket fixing member.

[0021] Thus, by reusing connectors as guide components, a single connector simultaneously achieves both detachable connection and movable guidance functions, reducing the number of parts, simplifying the device structure, and lowering the manufacturing cost and assembly difficulty of the graphics card mounting device. The connectors themselves can be made with hand-tightened screws, allowing for tool-free disassembly, replacement, and reinstallation of the bracket's movable components, further enhancing the tool-free convenience of the graphics card mounting device provided in this application.

[0022] Secondly, embodiments of this application provide a server, including: a chassis, including a motherboard and a crossbeam; a graphics card, plugged into the motherboard; and the graphics card mounting device provided in the first aspect of this application, wherein the bracket fixing component of the graphics card mounting device is connected to the graphics card, the crossbeam is an external component, and the adjusting component of the graphics card mounting device is locked to the crossbeam to fix the graphics card to the chassis.

[0023] Thus, the server provided in this application embodiment, by using a graphics card mounting device, can be compatible with graphics cards of different lengths and sizes, eliminating the need to design a dedicated fixed structure for each type of graphics card, thereby reducing the overall development cost of the server. The tool-free design of the graphics card mounting device allows for the installation, replacement, and maintenance of graphics cards without the need for any tools; operators can complete the task manually, shortening server production assembly time and on-site maintenance time, and improving work efficiency. The detachable modular design of the graphics card mounting device means that when the server is upgraded to use a new model of graphics card or a component wears out, only the corresponding bracket moving part or elastic part needs to be replaced, without replacing the entire graphics card mounting device, reducing upgrade and maintenance costs and improving the maintainability of the server. The graphics card mounting device in the server provided in this application embodiment has a simple structure and few parts, avoiding the problems of complex design and excessive size of graphics card mounting devices that occupy space at the rear of the graphics card, ensuring unobstructed internal heat dissipation airflow, and preventing the graphics card installation from affecting heat dissipation performance and chassis layout.

[0024] In one possible implementation, the crossbeam is provided with a limiting portion, and the bracket moving part of the graphics card mounting device is provided with a positioning member, which is located on the side of the bracket moving part away from the bracket fixing member; the positioning member can extend into the limiting portion to limit the displacement of the bracket moving part relative to the crossbeam in a direction perpendicular to the first direction.

[0025] Thus, through the mating structure where a mating part is provided on the crossbeam and one end of the positioning member extends into the mating part, the server provided in this embodiment of the application achieves the limiting of the support moving member relative to the crossbeam in a direction perpendicular to the first direction. A pre-positioning function is provided before the adjusting member is locked, ensuring the accuracy of the locking operation; an auxiliary limiting function is provided after locking, enhancing the stability and reliability of the connection.

Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0032] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0034] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0035] In related technologies, the mounting methods for server graphics cards (GPUs) are mostly based on single sheet metal fasteners. While this allows for mounting the same type of GPU, it necessitates redesigning mounting devices for GPUs of different lengths and sizes, increasing development time and costs. Although some adjustable GPU mounting devices exist, they suffer from the following drawbacks: First, the lack of tool-free and adjustable mounting methods affects the ease of GPU maintenance and replacement efficiency; second, the limited range of mounting options cannot meet diverse locking and stability requirements. Therefore, current GPU mounting methods are limited in scope and fail to simultaneously address installation needs such as flexibility, convenience, versatility, and reliability.

[0036] Based on this, this application provides a graphics card installation device that enables tool-free installation and length adjustment to meet the adaptation needs of graphics cards of different lengths and sizes.

[0037] like Figure 1 and Figure 2 As shown, the graphics card mounting device 1 provided in this application embodiment includes a bracket fixing component 10, a bracket moving component 20, a stop component 30, and an adjusting component 40.

[0038] The bracket holder 10 may be a generally elongated plate-like structure extending along a first direction, i.e., the length direction of the graphics card 602. The bracket holder 10 is used to connect to the tail end of the graphics card 602. The graphics card 602 includes opposing gold finger ends and a tail end connected to the bracket holder 10. The graphics card 602 is installed onto the server's motherboard. The motherboard may be a separate motherboard. In some cases, the graphics card 602 cannot be directly inserted vertically into the motherboard; the motherboard may also include a motherboard body and an adapter board. The adapter board is used to turn the slot orientation of the graphics card 602 horizontal, allowing the graphics card 602 to be installed parallel to the motherboard body.

[0039] Specifically, such as Figure 3 and Figure 4 As shown, a press-fit hand screw 103 can be provided on the bracket fixing component 10. This press-fit hand screw 103 can be fixed to the graphics card 602 without tools by engaging with the screw holes. Operators do not need to use screwdrivers or other tools, but can achieve this by... Figure 4 The manual rotation operation shown in the diagram, using the hand-tightening screw 103, completes the fixed connection between the bracket fastener 10 and the graphics card 602. This tool-free connection method improves the ease of installation and maintenance of the graphics card 602 and reduces the risk of hardware damage caused by improper tool operation.

[0040] The movable support 20 can also be a generally elongated plate-like structure extending along the first direction. The movable support 20 is movably connected to the fixed support 10, and the movable support 20 can move relative to the fixed support 10 along the first direction. Specifically, the movable support 20 can be slidably mounted on the fixed support 10, and the two can cooperate through a guide structure to achieve relative sliding.

[0041] The relative movement between the bracket movable part 20 and the bracket fixed part 10 can change the total length of the entire graphics card mounting device 1, thereby adapting to graphics cards 602 of different lengths and external components, such as the distance between the crossbeams 601 of the server 2 chassis.

[0042] For example, when the graphics card 602 is short, the distance between the tail end of the graphics card 602 and the external component is large, and the bracket moving member 20 moves away from the bracket fixing member 10 to increase the total length of the graphics card mounting device 1; when the graphics card 602 is long, the distance between the tail end of the graphics card 602 and the external component is small, and the bracket moving member 20 moves closer to the bracket fixing member 10 to shorten the total length of the graphics card mounting device 1. Because the bracket moving member 20 can move relative to the bracket fixing member 10, the same graphics card mounting device 1 can accommodate various graphics cards 602 of different lengths, eliminating the need to develop a dedicated fixing device for each graphics card 602, thereby reducing development costs.

[0043] The gear position assembly 30 is disposed between the bracket movable member 20 and the bracket fixed member 10, and is used to lock the bracket movable member 20 in multiple target gear positions. When the bracket movable member 20 is in different target gear positions, the distance between it and the bracket fixed member 10 along the first direction is not equal.

[0044] In other words, the gear shift assembly 30 provides multiple target gears. The operator can adjust the support moving part 20 to a target gear of a suitable length, or the support moving part 20 can adaptively move to a suitable target gear and fix the support moving part 20 relative to the support fixing part 10 at that target gear.

[0045] In one possible implementation, the gear shift assembly 30 can be in the form of a slot 3011 and a tooth engaging. One of the support moving part 20 and the support fixing part 10 is provided with a plurality of slots 3011 arranged along the first direction, and the other is provided with movable teeth. The teeth selectively engage with different slots 3011, thereby realizing the adjustment and locking of multiple target gears.

[0046] In another possible implementation, the gear shift assembly 30 can be in the form of a positioning pin and a positioning hole. One of the bracket moving part 20 and the bracket fixing part 10 is provided with a plurality of positioning holes arranged along the first direction, and the other is provided with a pluggable positioning pin. The positioning pin can be inserted into different positioning holes to lock different gears.

[0047] Adjusting member 40 is movably disposed on bracket movable member 20, and adjusting member 40 is used to fix bracket movable member 20 to external member. Adjusting member 40 can move relative to bracket movable member 20 in a first direction and lock to external member.

[0048] Specifically, the adjusting component 40 can be a hand-tightening screw. The adjusting component 40 can pass through a groove 201 on the bracket moving component 20. The adjusting component 40 can move along the first direction within the groove 201 and can also lock with the external component after being moved into position. When the adjusting component 40 is locked with the external component, the entire graphics card mounting device 1 is fixed inside the chassis, and the graphics card 602 is securely installed. The adjusting component 40 can be locked with the external component by hand-tightening or other methods, allowing operators to install and remove the graphics card mounting device 1 without the need for screwdrivers or other tools.

[0049] The adjusting member 40 is used to compensate for the gap between the support moving member 20 and the external component along the first direction when the support moving member 20 is in any target position. Figure 2 As shown, along the first direction, the movable stroke of the adjusting member 40 relative to the support moving member 20 can be no greater than the distance L between two adjacent target gears. The gear assembly 30 provides multiple target gears, and adjacent target gears can have a preset distance L, for example, L can be any value from 5mm to 10mm. If adjustment is made solely by the gear assembly 30, the support moving member 20 can only be locked in a few target gears, while the actual fixed position of the external component is usually arbitrary and may not be exactly aligned with a target gear. Therefore, when the support moving member 20 is in a target gear, there may be a gap between it and the external component along the first direction that is smaller than the preset distance L. The size of this gap depends on the difference between the current gear and the actual position of the external component. The adjusting member 40 is used to compensate for this gap, and its continuous movement provides a small range of compensation adjustment, with an adjustment range of 5mm to 10mm. The adjustment stroke of the adjusting member 40 can cover the preset distance between adjacent gears, so that the compensation range of the adjusting member 40 in the current gear matches the distance between adjacent gears. The bracket moving part 20 is coarsely adjusted by the stop assembly 30 to bring it close to the external component, and then finely adjusted by the adjuster 40 to compensate for any remaining gap, so that the bracket moving part 20 is fixed to the external component. By using the stop assembly 30 for coarse adjustment and the adjuster 40 for fine adjustment, the graphics card mounting device 1 provided in this embodiment achieves stepless adjustment to accommodate different graphics card 602 lengths, and can adapt to graphics cards 602 of any length and size. This eliminates the need to develop dedicated fixing brackets for each type of graphics card 602, thereby reducing development costs.

[0050] Thus, the graphics card mounting device 1 provided in this embodiment achieves a wide range of coarse adjustments through the position component 30 and a small range of continuous fine adjustments through the adjustment component 40. The combination of these two components enables stepless adjustment of the total length of the graphics card mounting device 1, accommodating graphics cards 602 of different lengths and sizes. This improves the reusability of the graphics card mounting device 1 and reduces development cycle and cost. The bracket fixing component 10 can be connected to the graphics card 602 using hand-tightened screws or similar methods, and the adjustment component 40 can be secured to external components using hand-tightening locking or similar methods. Operators can complete installation and disassembly without the need for screwdrivers or other tools. This tool-free design simplifies the operation process and shortens the installation and maintenance time of the graphics card 602.

[0051] like Figure 1 and Figure 5 As shown, in some embodiments, the support moving member 20 has a groove 201 extending along a first direction. The groove 201 is an elongated opening or a recess, and its extending direction is consistent with the moving direction of the support moving member 20. The length of the groove 201 determines the movable travel range of the adjusting member 40 relative to the support moving member 20.

[0052] The adjusting member 40 is movably disposed within the slide groove 201. Specifically, a portion of the adjusting member 40 (e.g., the shank of a hand-tightening screw) passes through the slide groove 201 and is able to slide within the slide groove 201 in a first direction. A movable engagement is formed between the adjusting member 40 and the slide groove 201, allowing the adjusting member 40 to move continuously along the first direction within the length of the slide groove 201, enabling position adjustment without the aid of tools.

[0053] The adjusting member 40 can be fixed relative to the support moving member 20 at multiple consecutive positions along the first direction in the slide groove 201. That is, the adjusting member 40 can not only slide within the slide groove 201, but also remain fixed relative to the support moving member 20 after sliding to any desired position.

[0054] In one possible implementation, the adjusting member 40 can be a hand-tightening screw. When the operator manually tightens the adjusting member 40, the head of the adjusting member 40 presses against the surface of the support moving member 20, using friction to fix the adjusting member 40 in the current position of the slide groove 201. When the adjusting member 40 is loosened, the friction disappears, and the adjusting member 40 can move along the slide groove 201 again.

[0055] In another possible implementation, a locking structure (such as an eccentric cam) can be provided between the adjusting member 40 and the slide 201, and the adjusting member 40 can be clamped at any position in the slide 201 by operating the locking structure.

[0056] The adjusting member 40 is also used for locking with external components. After the adjusting member 40 moves to the target position within the slide 201, it can be fixedly connected to the external component. For example, the adjusting member 40 can pass through the slide 201 and engage with the threaded hole or locking hole on the crossbeam 601. By tightening the adjusting member 40, the bracket moving member 20 is pressed between the head of the adjusting member 40 and the crossbeam 601, thereby fixing the entire graphics card mounting device 1 to the chassis.

[0057] It should be noted that the continuous travel of the adjusting component 40 within the slide 201 is less than the preset distance between adjacent target positions, thus achieving a slight compensation adjustment after the coarse adjustment of the position assembly 30. When the position assembly 30 locks the bracket moving component 20 to a target position, the adjusting component 40 may not yet be precisely aligned with the locking holes on the crossbeam 601. At this point, the operator can slightly move the adjusting component 40 within the length of the slide 201 to precisely align it with the locking holes on the crossbeam 601, and then tighten the lock. This slight compensation adjustment function fills the gaps between multiple target positions, working in conjunction with the coarse adjustment of the position assembly 30 to achieve stepless adjustment of the total length of the graphics card mounting device 1.

[0058] Thus, the graphics card mounting device 1 provided in this application embodiment, through the cooperation of the sliding groove 201 opened on the bracket moving part 20 and the adjusting part 40, allows the adjusting part 40 to move continuously in the first direction within the sliding groove 201 and be fixed at any position, providing flexible micro-adjustment capability and eliminating installation length deviation caused by the distance between target levels. The adjusting part 40 serves both to lock the bracket moving part 20 to the external component and to perform micro-compensation adjustment, serving multiple purposes and simplifying the structure of the graphics card mounting device 1. The adjusting part 40 can be in the form of a hand-tightening screw, allowing operators to complete the movement, positioning, and locking operations of the adjusting part 40 without the aid of any tools, achieving true tool-free installation. The adjusting part 40 can be fixed at any position within the sliding groove 201, enabling the graphics card mounting device 1 of this application embodiment to adapt to graphics cards 602 of any length, rather than being limited to the installation distance corresponding to a few target levels, thus improving the versatility and adaptation accuracy of the graphics card mounting device 1.

[0059] like Figure 1 and Figure 6 As shown, in the graphics card installation device 1 provided in this application embodiment, the gear component 30 has a locked state and an unlocked state. Figure 1 The gear shift assembly 30 is shown in a locked state, which fixes the support moving member 20 relative to the support fixing member 10 and prevents the support moving member 20 from moving relative to the support fixing member 10 in the first direction. Figure 6The gear shift assembly 30 is shown in the unlocked state, whereby the gear shift assembly 30 releases the constraint on the support moving member 20, allowing the support moving member 20 to move freely relative to the support fixing member 10 in the first direction.

[0060] like Figure 1 and Figure 5 As shown, the graphics card mounting device 1 also includes a first elastic element 50. The first elastic element 50 is disposed between the bracket fixing member 10 and the bracket moving member 20. The first elastic element 50 can be a compression spring, a spring sheet, or other element with the ability to store and release elastic potential energy. When the bracket moving member 20 moves relative to the bracket fixing member 10 along a first direction ( Figure 6 When the first elastic element 50 moves towards the bracket fixing member 10 in the X direction, it is compressed and stores elastic potential energy. The elastic potential energy storage performance of the first elastic element 50 can be determined according to the different models, lengths and installation space of the graphics card 602.

[0061] For example, during the actual installation of the graphics card mounting device 1, the operator first adjusts the graphics card mounting device 1 to its initial state. In this initial state, the stop assembly 30 is locked, the bracket moving part 20 is positioned close to the bracket fixing part 10, and the first elastic member 50 is in a compressed and energy-storing state. Then, the operator inserts the graphics card 602 and the graphics card mounting device 1 fixed thereon into the chassis of the server 2, so that the gold finger end of the graphics card 602 is inserted into the motherboard inside the server 2, and the graphics card mounting device 1 is located between the tail end of the graphics card 602 and the external component (e.g., the chassis crossbeam 601).

[0062] Subsequently, the operator operates the gear shift assembly 30 to switch it from the locked state to the unlocked state. When the gear shift assembly 30 switches to the unlocked state, the elastic potential energy stored in the first elastic element 50 is released. The first elastic element 50 drives the bracket moving part 20 to move away from the bracket fixing part 10 in the first direction, that is, to extend towards the external component. The bracket moving part 20 continues to move under the drive of the first elastic element 50 until it abuts against the external component. Since the external component is fixed, and the different lengths of the graphics card 602 will result in different distances from the tail end of the graphics card 602 to the crossbeam 601, the extension length of the bracket moving part 20 driven by the first elastic element 50 will adaptively adapt to this distance, without the need for manual measurement or pre-adjustment by the operator.

[0063] When the bracket moving part 20 comes into contact with the external component, its movement naturally stops. At this time, the operator switches the locking assembly 30 from the unlocked state back to the locked state. After the locking assembly 30 is relocked, the bracket moving part 20 is fixed in its current target position, that is, the position of the bracket moving part 20 relative to the bracket fixing part 10 is locked, and the total length of the graphics card mounting device 1 is fixed. The operator makes a slight length compensation adjustment using the adjusting part 40 to lock the bracket moving part 20 to the external component, completing the installation of the graphics card 602.

[0064] It should be noted that the action of switching the gear position component 30 from the unlocked state back to the locked state can be manually triggered by the operator, or it can be automatically completed by the reset action of the gear position component 30 after the first elastic element 50 drives the bracket moving part 20 to move into place. Regardless of the method used, as long as the gear position component 30 can lock the bracket moving part 20 in the current target gear position after the bracket moving part 20 abuts against the external component, the above-mentioned technical effect of this application can be achieved.

[0065] Thus, the graphics card mounting device 1 provided in this embodiment, through the setting of the first elastic element 50, allows the bracket moving part 20 to automatically extend or be further compressed under the action of external force after unlocking, until it abuts against the external component. This eliminates the need for operators to pre-measure the distance from the tail end of the graphics card 602 to the crossbeam 601 outside the chassis, and also eliminates the need to manually pull out the bracket moving part 20 and perform repeated trial installations. The entire length adaptation process is automatically completed inside the chassis, simplifying the installation operation and improving assembly efficiency. Furthermore, the positioning component 30 locks the bracket moving part 20 to the current target position after it abuts against the external component, ensuring the length stability of the graphics card mounting device 1 before locking, and providing a reliable positional reference for the subsequent locking operation of the adjustment component 40.

[0066] In some embodiments, the gear position assembly 30 includes a snap-fit ​​member 301. The snap-fit ​​member 301 is disposed on the support movable member 20.

[0067] Specifically, one end of the snap-fit ​​member 301 can be fixedly installed on the bracket movable member 20, or it can be integrally formed with the bracket movable member 20. The other end of the snap-fit ​​member 301 extends into the screw hole 104 provided on the bracket fixing member 10. The first elastic member 50 can be sleeved on the outside of the snap-fit ​​member 301, with one end of the first snap-fit ​​member 301 abutting against the bracket fixing member 10 and the other end abutting against the bracket movable member.

[0068] The latching member 301 can be a columnar structure extending along a first direction, and has multiple spaced slots 3011 along the first direction. The multiple slots 3011 correspond to multiple target positions; that is, the multiple slots 3011 are arranged along the first direction, and the spacing between adjacent slots 3011 corresponds to the spacing between adjacent target positions. Each slot 3011 is used to cooperate with the locking member 302 to lock the support moving member 20 relative to the support fixing member 10 at a certain target position. The shape of the slot 3011 can be V-shaped, arc-shaped, rectangular, or other structures capable of forming a stable engagement with the locking member 302.

[0069] In some embodiments, the gear shift assembly 30 includes a locking member 302. The locking member 302 may be configured as a sheet structure and have an operating portion at one end to facilitate the application of force by an operator.

[0070] The locking member 302 is movably mounted on the bracket fixing member 10 and can move between a locked position and a released position. When the locking member 302 is in the locked position, the gear shift assembly 30 is in a locked state; when the locking member 302 is in the released position, the gear shift assembly 30 is in an unlocked state.

[0071] The moving direction of the locking member 302 can be a second direction that intersects with the first direction. The second direction can be perpendicular or nearly perpendicular to the first direction to ensure that the switching of the locking member 302 between the locked position and the unlocked position does not interfere with the movement of the bracket moving member 20 along the first direction.

[0072] When the locking member 302 is in the locked position, it engages with one of the slots 3011 of the latching member 301, thereby locking the support moving member 20 at a target position. At this time, the locking member 302 restricts the movement of the latching member 301 along the first direction. Since the latching member 301 is fixed to the support moving member 20, the position of the support moving member 20 relative to the support fixing member 10 is locked, that is, the support moving member 20 is fixed at the currently located target position. The engagement between the locking member 302 and the slot 3011 can be a mechanical insert fit, with a portion of the locking member 302 extending into the slot 3011, and the limiting effect is achieved by the blocking action of the side wall of the slot 3011 on the locking member 302.

[0073] When the locking member 302 is in the released position, the locking member 302 disengages from the latching member 301. At this time, the locking member 302 no longer obstructs the latching member 301, and the latching member 301 can move freely relative to the locking member 302 in the first direction, thereby allowing the bracket moving member 20 to move relative to the bracket fixing member 10 in the first direction to different target positions.

[0074] like Figure 2As shown, when the locking member 302 is engaged in the slot 3011 of the connector 301, the adjusting member 40, in its unadjusted state, can be located at the leftmost position of the slide groove 201 on the bracket moving member 20, that is, at the extreme position in the slide groove 201. Then, the operator moves the adjusting member 40 away from the graphics card 602 (i.e., towards the other end of the elongated hole) to a suitable position and locks it. Since the range of motion of the adjusting member 40 in the slide groove 201 is less than the preset distance L between adjacent slots 3011 of the connector 301, when the locking member 302 is locked in a certain slot 3011, the adjusting member 40 can continuously move from the leftmost (minimum compensation position) to the rightmost (maximum compensation position) of the elongated hole, or move to any position in between as needed, thereby completing the stepless adjustment function of the total length of the graphics card mounting device 1.

[0075] In some embodiments, the gear shift assembly 30 includes a second elastic element 303. The second elastic element 303 is connected between the bracket fixing member 10 and the locking member 302. The second elastic element 303 may be a tension spring, compression spring, torsion spring, sheet spring, or other element with elastic reset function.

[0076] The second elastic element 303 is used to drive the locking element 302 to reset from the released position to the locked position. That is, when the operator applies external force to move the locking element 302 from the locked position to the released position, the second elastic element 303 is stretched, compressed, or twisted to store elastic potential energy; when the operator releases the locking element 302, the second elastic element 303 releases the stored elastic potential energy, driving the locking element 302 to automatically return from the released position to the locked position. This eliminates the need for the operator to manually move the locking element 302 back to the locked position after adjusting the length of the graphics card mounting device 1; simply releasing the locking element 302 automatically locks the device, further improving operational convenience.

[0077] When it is necessary to adjust the overall length of the graphics card mounting device 1, such as Figure 6 As shown, the operator first overcomes the elastic force of the second elastic element 303 and applies a lifting force in the Y2 direction to the locking element 302, operating the locking element 302 to move it from the locked position to the released position. At this time, the locking element 302 disengages from the slot 3011 of the latching element 301, and the latching element 301 and the bracket moving element 20 fixed thereto are in a state of free movement.

[0078] Then, the operator can push or pull the bracket moving part 20 in the first direction, or rely on other driving mechanisms (such as the first elastic member 50) to automatically drive the bracket moving part 20 to move relative to the bracket fixing member 10 to the desired target position. During this process, the latching member 301 moves together with the bracket moving part 20, and the multiple latching slots 3011 on it pass through the position of the locking member 302 in sequence.

[0079] After the support moving member 20 moves to the target position, the operator releases the locking member 302. Driven by the second elastic member 303, the locking member 302 automatically resets from the released position to the locked position, and the locking member 302 moves along the... Figure 1 Move in the Y1 direction. After resetting, the locking member 302 engages with the corresponding slot 3011 on the locking member 301, locking the bracket moving member 20 in the current target position.

[0080] Thus, the latching assembly 30 includes a latching member 301, a locking member 302, and a second elastic member 303. Multiple spaced slots 3011 on the latching member 301 engage with the movable locking member 302, allowing the bracket moving member 20 to be selectively fixed at different distances from the bracket fixing member 10. This enables the same graphics card mounting device 1 to accommodate various graphics cards 602 of different lengths, eliminating the need to develop dedicated fixing devices for each graphics card 602. Furthermore, the second elastic member 303 provides the locking member 302 with an automatic reset function. The operator only needs to manually pull the locking member 302 to move it from the locked position to the released position, at which point the bracket moving member 20 can freely adjust its distance from the bracket fixing member 10. After adjustment, the operator simply releases the locking member 302, which automatically resets to the locked position under the drive of the second elastic member 303 and engages with the corresponding slot 3011. The entire adjustment process requires no tools; operators can switch and lock gears manually, achieving truly tool-free installation and improving the ease of installing and replacing the 602 graphics card.

[0081] In some embodiments, in the graphics card mounting device 1 provided in this application, the locking member 302 is movable along a second direction. The second direction may be perpendicular to or nearly perpendicular to the first direction.

[0082] The locking and releasing positions are arranged along the second direction, meaning that different positions of the locking member 302 in the second direction correspond to the locked and unlocked states of the gear shift assembly 30, respectively. When the locking member 302 moves along the second direction, its relative positional relationship with the latching member 301 changes, thereby switching between the locked and unlocked states of the gear shift assembly 30.

[0083] In some embodiments, the locking member 302 has an engaging hole 3021. The engaging hole 3021 includes a first hole segment 30211 and a second hole segment 30212 arranged along a second direction and communicating with each other. The first hole segment 30211 and the second hole segment 30212 are arranged sequentially along the second direction and are interconnected to form an integral hole structure. The diameter of the second hole segment 30212 is larger than the diameter of the locking member 301, and the diameter of the first hole segment 30211 is smaller than the diameter of the locking member 301.

[0084] Specifically, since the diameter of the first hole 30211 is smaller than the diameter of the latching member 301, when the latching member 301 is located inside the first hole 30211, it cannot be dislodged from the first hole 30211, and the wall of the first hole 30211 can engage with the slot 3011 on the latching member 301, thereby achieving locking. Since the diameter of the second hole 30212 is larger than the diameter of the latching member 301, when the latching member 301 is located inside the second hole 30212, there is a gap between the latching member 301 and the wall of the second hole 30212, allowing the latching member 301 to move freely in the first direction within the second hole 30212, thereby achieving unlocking.

[0085] For example, the locking element 302 is pulled by the operator along the second direction (e.g., Figure 6 The locking member 302 moves relative to the locking member 302 in the Y2 direction (as shown) to reach the released position, at which point the second hole segment 30212 is aligned with the latching member 301 in the first direction. The latching member 301 is located within the second hole segment 30212. Since the diameter of the second hole segment 30212 is larger than the diameter of the latching member 301, the latching member 301 can move freely relative to the locking member 302 in the first direction. At this time, the gear assembly 30 is in the unlocked state, allowing the bracket moving member 20 to move relative to the bracket fixing member 10 in the first direction (as shown). Figure 6 The length can be adjusted by moving the device in the X direction (as shown).

[0086] When the support moving part 20 moves to contact with the external component, the operator releases the locking part 302, and the locking part 302 moves along the... Figure 1 The locking member 302 moves in the Y1 direction and resets to the locked position. The reset of the locking member 302 can be automatically driven by the second elastic member 303 or manually pushed by the operator. During the movement of the locking member 302 from the released position to the locked position, the engaging member 301 enters the first hole section 30211 from the second hole section 30212. Since the diameter of the first hole section 30211 is smaller than the diameter of the engaging member 301, the engaging member 301 entering the first hole section 30211 is held in place by the hole wall of the first hole section 30211, and the hole wall of the first hole section 30211 engages with the corresponding slot 3011 of the engaging member 301, thereby locking the support moving member 20 to the current target position.

[0087] It should be noted that during the process of the latching member 301 moving from the second hole segment 30212 into the first hole segment 30211, the relative movement direction between the latching member 301 and the locking member 302 includes a second direction component (generated by the movement of the locking member 302) and a first direction component (generated by the movement of the latching member 301 along with the moving member 20 of the bracket). The combination of the two movements enables the latching member 301 to smoothly transition from the second hole segment 30212 to the first hole segment 30211 and accurately engage with the corresponding slot 3011.

[0088] Thus, by using the difference in diameter between the first hole segment 30211 and the second hole segment 3021 of the engaging hole 3021 on the locking member 302, reliable switching between the locked and unlocked states between the locking member 302 and the engaging member 301 is achieved. When the locking member 302 is in the released position, the larger diameter second hole segment 30212 aligns with the engaging member 301, providing space for the engaging member 301 to move, allowing the bracket moving member 20 to be smoothly adjusted along the first direction, thereby realizing the length adjustment of the graphics card mounting device 1. When the locking member 302 is reset to the locked position, the smaller diameter first hole segment 30211 engages with the engaging member 301 and forms a reliable lock with the slot 3011 on the engaging member 301. This structural design requires no tools; the operator only needs to overcome the elastic force of the second elastic member 303 to move the locking member 302 to achieve the switching between locking and unlocking. The entire operation process is quick and reliable.

[0089] In some embodiments, the locking member 302 is provided with a first guide hole 3022 extending in a second direction.

[0090] The first guide hole 3022 can be an elongated hole or groove formed in the locking member 302, and its extending direction is consistent with the moving direction of the locking member 302 (i.e., the second direction). The first guide hole 3022 has a first end and a second end opposite to each other along the second direction. The first end and the second end are respectively the two endpoints of the first guide hole 3022 in the second direction.

[0091] In some embodiments, the gear shift assembly 30 further includes a guide 304 disposed on the bracket fixing member 10. The guide 304 may be a stepped screw, a pin, a guide post, or other elements with a guiding function.

[0092] The guide member 304 is fixedly installed on the bracket fixing member 10, and its position remains fixed relative to the bracket fixing member 10. The guide member 304 passes through the first guide hole 3022, that is, the guide member 304 extends into the first guide hole 3022. The limiting cooperation between the guide member 304 and the first guide hole 3022 guides the movement direction of the locking member 302, improving the smoothness of the movement of the locking member 302 in the second direction, and also limits the travel of the locking member 302 in the second direction. The guide member 304 can be a detachable component such as a stepped screw, which facilitates the installation, disassembly and maintenance of the locking member 302.

[0093] Specifically, a sliding fit is formed between the wall of the first guide hole 3022 and the outer wall of the guide member 304. When the locking member 302 moves along the second direction under the action of an external force, the first guide hole 3022 slides relative to the guide member 304. When the locking member 302 is in the released position, the guide member 304 abuts against the first end of the first guide hole 3022. At this time, the locking member 302 moves to a limit position along the second direction, and the guide member 304 contacts the wall of the first end of the hole, preventing the locking member 302 from moving further in the second direction. In this position, the second hole segment 30212 on the locking member 302 corresponds to the position of the latching member 301, that is, the second hole segment 30212 is aligned with the latching member 301 along the first direction, so that the latching member 301 is located inside the second hole segment 30212. Since the diameter of the second hole segment 30212 is larger than the diameter of the latching member 301, the latching member 301 can move freely relative to the locking member 302 along the first direction, thereby achieving unlocking.

[0094] When the locking member 302 is in the locked position, the guide member 304 abuts against the second end of the first guide hole 3022, that is, the guide member 304 contacts the hole wall of the second end of the first guide hole 3022, forming a structural limit. At this time, since the position of the guide member 304 is fixed, the locking member 302 cannot continue to move in the first direction, and the locking member 302 is limited to the locked position. At the same time, in this position, the first hole segment 30211 on the locking member 302 corresponds to the position of the latching member 301, that is, the first hole segment 30211 is aligned with the latching member 301 along the first direction, so that the latching member 301 is located in the first hole segment 30211 and engages with the slot 3011, thereby achieving locking.

[0095] Therefore, the cooperation between the guide member 304 and the first guide hole 3022 not only provides movement guidance for the locking member 302, but more importantly, through the abutment and limiting of the first end and the second end, it precisely defines the two extreme working positions of the locking member 302—the locked position and the released position. Simultaneously, these two extreme positions respectively align the first hole segment 30211 with the latching member 301 and the second hole segment 30212 with the latching member 301, thereby corresponding the position of the locking member 302 with different segments of the engaging hole 3021.

[0096] Thus, through the cooperation of the guide member 304 and the first guide hole 3022, precise control of the movement stroke of the locking member 302 is achieved. The abutment between the guide member 304 and the first end of the first guide hole 3022 defines the locking position, and at the same time, ensures that the first hole segment 30211 is accurately aligned with the latching member 301. The abutment between the guide member 304 and the second end of the first guide hole 3022 defines the release position, and at the same time, ensures that the second hole segment 30212 is accurately aligned with the latching member 301. In this way, the operator does not need to judge whether the locking member 302 has moved into place by feel; simply pulling or releasing the locking member 302 ensures that the corresponding hole segment is accurately aligned with the latching member 301, reducing the difficulty of operation and the requirements for operator proficiency.

[0097] In some embodiments, such as Figure 5 As shown, the movable bracket 20 and the fixed bracket 10 are detachably connected via a connector 203. Detachable connection means that the movable bracket 20 and the fixed bracket 10 can be separated and reassembled. The connector 203 can be a screw, bolt, clip, pin, or other standard fastener capable of detachable fixing.

[0098] Specifically, the connector 203 passes through the movable bracket 20 and connects to the fixed bracket 10, thereby detachably fixing the movable bracket 20 and the fixed bracket 10 together. When it is necessary to separate the movable bracket 20 from the fixed bracket 10, the operator only needs to remove the connector 203 to remove the movable bracket 20 from the fixed bracket 10; when it is necessary to reassemble, the movable bracket 20 is placed in the corresponding position on the fixed bracket 10, and the connector 203 is reinstalled to complete the fixing.

[0099] The movable bracket 20 and the fixed bracket 10 are detachably connected via a connector 203, allowing the movable bracket 20 to be replaced with components of different sizes as needed. It is understood that different lengths or models of graphics cards 602 may have different requirements regarding the total length range, length adjustment stroke, structural strength, or manufacturing materials of the graphics card mounting device 1. By disassembling the connector 203, the operator can remove the original movable bracket 20, replace it with another movable bracket 20 of different length, structure, or material, and then reinstall the connector 203, thus adapting the graphics card mounting device 1 to the new graphics card 602 specification.

[0100] For example, for a longer graphics card 602, the distance from the tail end of the graphics card 602 to the crossbeam 601 is smaller, and the required installation length of the bracket moving part 20 is shorter. In this case, the bracket moving part 20 with a shorter length in the first direction can be used. For a shorter graphics card 602, the distance from the tail end of the graphics card 602 to the crossbeam 601 is larger. In this case, the bracket moving part 20 with a longer length in the first direction can be used. In addition, for a heavier graphics card 602, a bracket moving part 20 with a stronger structure and thicker walls or a bracket fixing part 10 can be used. For a server 2 chassis with limited space, a more compact bracket moving part 20 can be used.

[0101] Furthermore, the spacing of the slots 3011 of the latching parts 301 configured with different bracket moving parts 20 can also be different, thereby achieving preset spacing for different target levels. For application scenarios where there is ample installation space for the graphics card 602, a bracket moving part 20 with a larger spacing of slots 3011 can be selected, for example, a spacing of 5mm or 10mm between adjacent slots 3011. In this case, the operator can quickly pull out the bracket moving part 20 to the approximate position, and then complete the installation by making slight compensation through the adjusting part 40. For application scenarios where there is limited installation space for the graphics card 602, a bracket moving part 20 with a smaller spacing of slots 3011 can be selected, for example, a spacing of 1mm or 2mm between adjacent slots 3011. In this case, the leveling component 30 itself already provides relatively fine adjustment capabilities, and the adjusting part 40 only needs to make very small compensations to achieve precise locking.

[0102] Furthermore, besides replacing the bracket moving part 20 itself, the detachable connection also allows for the replacement of other components in the locking assembly 30. For example, when different locking forces or different adjustment feels are required, the connector 203 can be disassembled and replaced with a first elastic element 50 (compression spring) or a second elastic element 303 (tension spring) with different elastic coefficients. When the slot 3011 on the latch 301 wears out due to long-term use, the connector 203 can be disassembled and replaced with a new latch 301 or the entire bracket moving part 20. This modular design extends the overall lifespan of the graphics card mounting device 1 and reduces maintenance costs.

[0103] Thus, the bracket moving part 20 and the bracket fixing part 10 are detachably connected through the connector 203. The same bracket fixing part 10 can be used with various bracket moving parts 20 of different specifications to form their own modular designs. The bracket fixing part 10 and the bracket moving part 20 can be designed separately according to actual needs, which can cover the installation requirements of graphics cards 602 of different lengths, weights and models, reducing the complexity of the development of the graphics card installation device 1. The detachable connection makes the graphics card installation device 1 have good scalability and maintainability. When the server 2 is upgraded to use a new model of graphics card 602, it is not necessary to replace the entire device. Only the bracket moving part of the corresponding specification can be replaced. When a part is worn, only the damaged part needs to be replaced, without scrapping the entire graphics card installation device 1.

[0104] In some embodiments, the connector 203 passes through and is fixed to the support movable member 20. The connector 203 may be a stepped screw, bolt, or other element with a fastening function.

[0105] The bracket fixing member 10 may include a protruding first mounting portion 101, and the bracket moving member 20 may be provided with a second mounting portion 202. The second mounting portion 202 is provided with a mounting groove, and the first mounting portion 101 can be inserted into the mounting groove. The bracket fixing member 10 also includes a second guide hole 102. The second guide hole 102 is formed on the mounting portion of the bracket fixing member 10 and has a preset length along a first direction.

[0106] The second guide hole 102 can be an oblong or waist-shaped hole, with its length direction aligned with the first direction. The connector 203 passes through the second guide hole 102 and further through a corresponding hole on the bracket moving member 20, and then connects to the second assembly part 202 of the bracket fixing member 10. In this way, the connector 203 simultaneously serves the dual functions of detachable connection and guiding the movement of the bracket moving member 20.

[0107] In this embodiment, the connector 203, in addition to serving as a detachable connection, is also reused as a guide for the moving bracket 20. The connector 203 passes through the second guide hole 102, and a sliding fit is formed between the rod portion of the connector 203 and the wall of the second guide hole 102. When the moving bracket 20 moves along the first direction under the drive of an external force or an elastic element, the connector 203 slides relative to it within the second guide hole 102 along the first direction. Since the connector 203 is fixed to the bracket fixing member 10, and the second guide hole 102 is formed on the bracket fixing member 10, the cooperation between the connector 203 and the second guide hole 102 provides guidance for the movement of the moving bracket 20, preventing the moving bracket 20 from deviating or jamming during movement.

[0108] Meanwhile, the second guide hole 102 has a preset length along the first direction. This preset length limits the sliding range of the connector 203 within the second guide hole 102, thereby limiting the travel distance of the support moving member 20 relative to the support fixing member 10. Specifically, when the support moving member 20 moves to a certain extreme position, the connector 203 abuts against one end wall of the second guide hole 102, preventing the support moving member 20 from moving further; when the support moving member 20 moves to another extreme position, the connector 203 abuts against the other end wall of the second guide hole 102, preventing the support moving member 20 from moving further in the opposite direction. Through the length design of the second guide hole 102, the range of motion of the support moving member 20 can be precisely controlled.

[0109] In this embodiment, the connector 203 achieves multiple uses. On one hand, the connector 203 acts as a fastener, detachably connecting the bracket moving part 20 and the bracket fixing part 10, allowing them to be separated and reassembled. On the other hand, the connector 203 acts as a guide 304, cooperating with the second guide hole 102 to guide the movement of the bracket moving part 20 and limit its travel. This functional reuse simplifies the overall structure of the graphics card mounting device 1, reducing component costs and assembly complexity.

[0110] It should be noted that the engagement of connector 203 with the second guide hole 102 can work in conjunction with the engagement of guide 304 with the first guide hole 3022. Guide 304 and the first guide hole 3022 are used to guide the movement of locking member 302 in the second direction, while connector 203 and the second guide hole 102 are used to guide the movement of bracket moving member 20 in the first direction. Their functions are clearly defined, jointly ensuring the smooth movement and precise positioning of all moving parts in the graphics card mounting device 1.

[0111] Thus, by reusing the connector 203 as the guide 304, a single connector 203 simultaneously achieves both detachable connection and movable guidance functions, reducing the number of parts, simplifying the device structure, and lowering the manufacturing cost and assembly difficulty of the graphics card mounting device 1. The connector 203 itself can be made using hand-tightening screws, allowing for tool-free disassembly, replacement, and reinstallation of the bracket moving part 20, further enhancing the tool-free convenience of the graphics card mounting device 1 provided in this application.

[0112] In some embodiments, the number of latching members 301 can be two, located on both sides of the second assembly portion 202 along the second direction. This symmetrical arrangement on both sides makes the force on the bracket moving member 20 more balanced in the locked state, preventing tilting or shaking caused by locking on one side, and improving the stability and reliability of locking. In addition, the latching members 301 arranged on both sides share the supporting force of the rear end of the graphics card 602 and the vibration and impact during transportation and use, dispersing the force on a single latching member 301, and improving the structural strength and durability of the entire graphics card mounting device 1. More importantly, when the spacing of the slots 3011 on the two latching members 301 is consistent, the locking on both sides is carried out synchronously, ensuring that the bracket moving member 20 remains stable during movement and is not prone to deflection.

[0113] Thus, by arranging two card connectors 301 on both sides, the graphics card mounting device 1 of this application embodiment not only achieves stepless adjustment and tool-free operation, but also further improves the stability of locking and the reliability of the structure.

[0114] like Figure 7 As shown, an embodiment of the second aspect of this application also provides a server 2, which includes a chassis, a graphics card 602, and a graphics card mounting device 1 as described above. The specific structure and working principle of the graphics card mounting device 1 have been described in detail in the above embodiments and will not be repeated here.

[0115] The chassis is the basic supporting structure of server 2, used to house and protect various electronic components inside server 2. The chassis includes a motherboard and a crossbeam 601. The motherboard is fixed horizontally or vertically inside the chassis and has PCIe slots for connecting expansion cards such as graphics card 602. The crossbeam 601 is an internal structural component of the chassis and can be located at the rear of the chassis, i.e., on the side opposite the motherboard slots, to provide a support and fixing point for the rear end of graphics card 602. The external component involved in the above embodiment is the crossbeam 601.

[0116] Graphics card 602 is an expansion card in server 2 used for processing graphics, images, or performing high-performance computing. The gold fingers of graphics card 602 can be inserted into a PCIe slot on the motherboard, enabling electrical connection and communication with the motherboard. The rear end of graphics card 602 is a free end, supported and fixed by graphics card mounting device 1 to prevent the graphics card 602 from sagging, shaking, or making poor contact due to its own weight or transportation vibrations.

[0117] The graphics card mounting device 1 can be any of the graphics card mounting devices 1 provided in the first aspect of this application. In the specific installation process, the bracket fixing part 10 of the graphics card mounting device 1 can be connected to the tail end of the graphics card 602 first. The bracket fixing part 10 can be fixed to the screw holes on the tail end of the graphics card 602 using a tool-free connection method such as a hand-tightening screw, without the need for a screwdriver or other tools. Then, the graphics card 602, together with the graphics card mounting device 1 fixed thereon, is installed into the computer case, so that the gold finger end of the graphics card 602 is inserted into the PCIe slot on the motherboard, and the graphics card mounting device 1 is located between the tail end of the graphics card 602 and the crossbeam 601 of the computer case.

[0118] The operator can adjust the length of the graphics card mounting device 1 using the positioning component 30. The positioning component 30 has multiple target positions. The operator can adjust the bracket moving part 20 to a target position that matches the current length of the graphics card 602, making the total length of the graphics card mounting device 1 approximately equal to the distance from the tail end of the graphics card 602 to the crossbeam 601. Then, the operator makes minor length compensation adjustments using the adjusting part 40. The adjusting part 40 passes through the slide groove 201 on the bracket moving part 20 and can move continuously in a first direction within the slide groove 201. The operator moves the adjusting part 40 to a position aligned with the locking hole on the crossbeam 601, and then locks the adjusting part 40 onto the crossbeam 601, simultaneously pressing and fixing the bracket movement, thus completing the fixation of the tail end of the graphics card 602 to the chassis.

[0119] Thus, by using the graphics card mounting device 1, the server 2 provided in this embodiment can be compatible with graphics cards 602 of different lengths and sizes, eliminating the need to design a dedicated fixing structure for each graphics card 602, thereby reducing the overall development cost of the server 2. The tool-free design of the graphics card mounting device 1 allows for the installation, replacement, and maintenance of the graphics card 602 without the aid of any tools; operators can complete the task manually, shortening the production assembly time and on-site maintenance time of the server 2 and improving work efficiency. The detachable modular design of the graphics card mounting device 1 means that when the server 2 is upgraded to use a new model of graphics card 602 or a component wears out, only the corresponding bracket moving part 20 or elastic part needs to be replaced, without replacing the entire graphics card mounting device 1, reducing upgrade and maintenance costs and improving the maintainability of the server 2. The graphics card mounting device 1 in the server 2 provided in this embodiment has a simple structure and few parts, avoiding the problems of complex design and excessive size that would occupy the rear space of the graphics card 602, ensuring unobstructed internal heat dissipation airflow of the server 2, and preventing the installation of the graphics card 602 from affecting heat dissipation performance and chassis layout.

[0120] In some embodiments, a buffer 70 may also be provided between the support movable member 20 and the crossbeam 601. The buffer 70 may be a Mylar sheet, a sponge layer, etc. The buffer 70 is used to provide cushioning when the two come into contact, absorb the impact force during installation, and protect the graphics card 602 and the mounting device from damage.

[0121] In some embodiments, the crossbeam 601 is provided with a limiting portion 6011. The graphics card mounting device 1 includes a positioning member 204, one end of which can extend into the limiting portion 6011 to limit the displacement of the bracket moving member 20 relative to the crossbeam 601 in a direction perpendicular to the first direction.

[0122] The crossbeam 601, as a structural component inside the chassis, has a limiting part 6011 on its side facing the rear end of the graphics card 602. This limiting part 6011 can be a positioning hole, positioning groove, recess, or other structure capable of interlocking with the positioning member 204. The position of the limiting part 6011 corresponds to the position of the positioning member 204 after the graphics card mounting device 1 is installed, ensuring that the positioning member 204 can accurately extend into the limiting part 6011.

[0123] The positioning member 204 is disposed on the support moving member 20 and is located on the side of the support moving member 20 away from the support fixing member 10. The positioning member 204 extends in the first direction to extend toward the crossbeam 601 and can extend into the limiting part 6011 provided on the crossbeam 601.

[0124] When the support moving member 20 moves to abut against the crossbeam 601 under the drive of the first elastic member 50 or under the push of an external force, the end of the positioning member 204 can be inserted into the limiting part 6011 on the crossbeam 601. The insertion and engagement of the positioning member 204 and the limiting part 6011 restricts the displacement of the support moving member 20 relative to the crossbeam 601 in a direction perpendicular to the first direction.

[0125] Specifically, the direction perpendicular to the first direction includes the vertical direction (i.e., the height direction of the chassis) and the horizontal direction (i.e., the width direction of the chassis). When the positioning member 204 is inserted into the limiting part 6011, the hole wall or groove wall of the limiting part 6011 abuts against the outer wall of the positioning member 204 to limit the relative displacement of the bracket moving member 20 in the vertical or horizontal direction.

[0126] Through the cooperation of the limiting part 6011 and the positioning part 204, before the adjusting part 40 is locked, the positioning part 204 and the limiting part 6011 have pre-positioned the position of the bracket moving part 20 relative to the crossbeam 601, preventing the bracket moving part 20 from shifting or shaking during the locking process of the adjusting part 40, thus ensuring the accuracy of the locking operation. Furthermore, after the adjusting part 40 is locked, the cooperation of the positioning part 204 and the limiting part 6011 acts as an auxiliary limiting mechanism, working together with the locking of the adjusting part 40 to further enhance the connection stability between the bracket moving part 20 and the crossbeam 601. In addition, when the server 2 is subjected to vibration or impact during transportation or use, the cooperation of the positioning part 204 and the limiting part 6011 can share some of the load, reducing the stress on the adjusting part 40 and improving the reliability and durability of the graphics card mounting device 1. Finally, the insertion and engagement of the positioning component 204 and the limiting part 6011 provides the operator with feedback on the correct position. When the positioning component 204 is smoothly inserted into the limiting part 6011, the operator can sense that the bracket moving component 20 has moved to the correct position, making it easier to determine whether subsequent locking operations can be performed.

[0127] Thus, through the mating structure where a mating part is provided on the crossbeam 601 and one end of the positioning member 204 extends into the mating part, the server 2 provided in this embodiment of the application achieves the limiting of the support moving member 20 relative to the crossbeam 601 in a direction perpendicular to the first direction. A pre-positioning function is provided before the adjusting member 40 is locked to ensure the accuracy of the locking operation; an auxiliary limiting function is provided after locking to enhance the stability and reliability of the connection.

[0128] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
