Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of graphics card installation, and in particular to an installation device and electronic equipment. BACKGROUND

[0002] With the continuous rise of the power consumption and heat dissipation of server graphics cards, the traditional air cooling heat dissipation method has been unable to meet the heat dissipation demand. The liquid cooling heat dissipation technology has gradually become the mainstream solution due to its high-efficiency heat dissipation performance. However, the liquid cooling graphics card faces new technical challenges in the installation and dismounting process. The liquid cooling graphics card needs to be precisely inserted into the interface of the liquid cooling assembly and the slot of the electronic device inside the server and the like electronic equipment. When the liquid cooling graphics card is connected to the interface of the liquid cooling assembly, a large rebound force is generated, so that double resistance needs to be overcome in the installation process. In the dismounting process, the rebound force when the liquid cooling graphics card is separated from the interface will instantaneously lift the liquid cooling graphics card, causing mechanical damage to the golden finger of the liquid cooling graphics card and the slot of the electronic device, and even causing permanent damage to the electronic equipment.

[0003] At present, there is a lack of auxiliary tools for the installation and dismounting of the liquid cooling graphics card in the market. The traditional manual installation method is not only inefficient, but also has many safety hazards, such as the difficulty in ensuring the vertical motion trajectory of the liquid cooling graphics card during installation, and the inability to effectively offset the rebound force of the interface of the liquid cooling assembly during dismounting. These problems seriously affect the maintenance efficiency and service life of the server.

[0004] Therefore, it is urgent to develop an installation device that can ensure the vertical motion of the liquid cooling graphics card during installation and dismounting, and effectively offset the rebound force of the interface of the liquid cooling assembly, so as to solve the technical problems in the current installation and maintenance process of the liquid cooling graphics card. SUMMARY

[0005] The present application provides an installation device and electronic equipment to at least solve the problem that the rebound force generated by the interface of the liquid cooling assembly when the liquid cooling graphics card is installed causes the liquid cooling graphics card to be unable to maintain a horizontal position, resulting in mechanical damage to the golden finger of the liquid cooling graphics card and the slot of the electronic device.

[0006] The present application provides an installation device suitable for installing a liquid cooling graphics card into the interface of a liquid cooling assembly and the slot of an electronic device in a box. The installation device includes a fixed base plate and a pressing plate. The fixed base plate is installed on an installation support in the box. The pressing plate is slidably arranged on the fixed base plate in the vertical direction. The pressing plate has a first position above the liquid cooling graphics card that is not assembled and a second position for pressing the liquid cooling graphics card into the interface and the slot. When the pressing plate is in the second position, the liquid cooling graphics card is prevented from being separated from the interface.

[0060] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0061] It should be noted that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. The terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements. The terms "parallel", "vertical", "equal" include the described case and the approximate case similar to the described case, and the approximate case is within the acceptable deviation range, wherein the acceptable deviation range is determined by considering the measurement being discussed and the error related to the measurement of a specific quantity (i.e. the limitation of the measurement system) by a person skilled in the art. For example, "parallel" includes absolute parallel and approximate parallel, wherein the acceptable deviation range of approximate parallel can be, for example, within 5°; "vertical" includes absolute vertical and approximate vertical, wherein the acceptable deviation range of approximate vertical can also be, for example, within 5°.

For a person skilled in the art, the specific meaning of the above terms in the present application can be understood in specific cases.

[0062] The traditional manual installation of liquid cooling graphics card has three technical problems: first, the lack of vertical guide mechanism causes the liquid cooling graphics card to tilt during installation, which easily damages the golden fingers and electronic devices of the liquid cooling graphics card; second, in the critical state before the liquid cooling graphics card is fastened, the reaction force of the liquid cooling plug will cause one end of the liquid cooling graphics card to be raised, causing misalignment and wear of the golden fingers and the slots of the electronic devices; third, the rebound force of the interface during disassembly will also cause the golden fingers to tilt and be damaged. The application of the installation device not only realizes precise vertical guidance during the installation process, but also stably holds the liquid cooling graphics card during the key process stage, effectively offsets the reaction force of the interface of the liquid cooling assembly, and simplifies the pressing operation process, thereby improving the installation efficiency.

[0063] In order to enable a person skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0064] Figure 1A perspective view of the mounting device provided by the embodiment of the present application is assembled in the box body; Figure 2 A front view of the mounting device provided by the embodiment of the present application.

[0065] The embodiment of the present application provides a mounting device, as shown in Figure 1 and Figure 2 As shown in the mounting device is suitable for mounting the liquid cooling graphics card 100 to the interface of the liquid cooling assembly and the slot of the electronic device in the box body, the mounting device 5 comprises a fixed base plate 51 and a pressing plate 52, the fixed base plate 51 is mounted on the mounting support in the box body; the pressing plate 52 is slidably arranged on the fixed base plate 51 in the vertical direction; the pressing plate 52 has a first position above the unmounted liquid cooling graphics card 100 and a second position for pressing the liquid cooling graphics card 100 into the interface of the liquid cooling assembly and the slot of the electronic device under the external force, and the pressing plate 52 continuously presses the liquid cooling graphics card 100 at the second position based on the external force. The liquid cooling graphics card 100 is prevented from being separated from the interface.

[0066] According to the embodiment of the present application, the mounting device comprises but is not limited to the mounting and dismounting of the liquid cooling graphics card 100 in the server, wherein the electronic device comprises the switching backplane 1 and the power supply backplane 2, the slot of the electronic device comprises but is not limited to the electrical connection arranged on the switching backplane 1 and the power supply backplane 2; the interface of the liquid cooling assembly comprises but is not limited to the liquid cooling plug arranged at the manifold end of the liquid cooling assembly.

[0067] In the mounting device of the embodiment of the present application, the unmounted liquid cooling graphics card 100 specifically refers to a transition state of the liquid cooling graphics card 100 in the mounting process, which specifically shows that the golden fingers (conducting contact pieces) of the liquid cooling graphics card 100 have been accurately aligned with the slots (such as electrical connectors) of the electronic device (such as the switching backplane 1 and the power supply backplane 2), and the liquid cooling male plug of the liquid cooling graphics card 100 also maintains axial alignment with the female plug (that is, the interface, such as the liquid cooling plug) of the liquid cooling assembly, but at this time, the golden fingers have not been completely inserted into the electrical connectors, and the liquid cooling male plug and the female plug have not been sealed and connected. The establishment of this position is guaranteed by the positioning cooperation of the fixed base plate 51 of the mounting device 5 and the mounting support, and the pressing plate 52 maintains a non-pressing state (usually with a gap of 1-3 mm) with the upper end surface of the liquid cooling graphics card 100 when being at the first position, which not only provides a visual alignment confirmation space for the operator, but also ensures the vertical precision of the subsequent pressing action. This design effectively solves the misalignment risk caused by blind operation in the traditional mounting, and provides a reliable initial positioning reference for the subsequent accurate pressing.

[0068] Specifically, the device realizes the horizontal stable installation of the liquid-cooled graphics card 100 through the cooperation of the mounting bracket in the box and the mounting device 5. The fixing base plate 51 and the mounting bracket ensure the stability of the installation reference, and the vertical sliding mechanism of the pressing plate 52 can accurately press the liquid-cooled graphics card 100 into the slot of the electronic device and the interface of the liquid-cooled assembly under the action of external force, and lock the pressing plate 52 relative to the fixing base plate 51 at the second position to continuously press the liquid-cooled graphics card 100, effectively offsetting the rebound force generated when the interfaces of the liquid-cooled assembly are docked. The mounting device improves the stability and reliability of the installation process, avoids damage to the gold fingers of the liquid-cooled graphics card 100 or the slots of the electronic device caused by deflection, simplifies the operation process, improves the work efficiency, and is especially suitable for the batch installation of the liquid-cooled graphics card 100 in a high-density server environment.

[0069] According to the embodiment of the application, the liquid-cooled graphics card 100 is first placed above the electronic device and the liquid-cooled assembly during installation, and then the fixing base plate 51 of the mounting device 5 is combined with the mounting bracket to ensure accurate overall positioning. The operator applies external force to push the pressing plate 52 vertically downward from the first position (above the liquid-cooled graphics card 100) to the second position, at which time the pressing plate 52 simultaneously presses the liquid-cooled graphics card 100 into the electrical connectors of the exchange backboard 1 and the power supply backboard 2 and the liquid-cooled plug of the liquid-cooled assembly. The pressure provided by the external force cooperates with the fixing base plate 51 to offset the rebound force of the liquid-cooled plug, maintaining the stability of the liquid-cooled graphics card 100 until the fastening of the fastener is completed. Reverse operation during disassembly can safely separate the liquid-cooled graphics card 100 from the liquid-cooled assembly and the electronic device.

[0070] In an exemplary embodiment, as shown in Figure 1 and Figure 2 The fixing base plate 51 is detachably mounted on the mounting bracket, the first end of the fixing base plate 51 is provided with a positioning portion 511, which is suitable for being combined with the rear bracket 4 at the first end of the mounting bracket; the second end of the fixing base plate 51 is provided with a locking mechanism 53, which is suitable for being locked to the front bracket 3 at the second end of the mounting bracket, and the locking between the second end of the fixing base plate 51 and the front bracket 3 is released by operation to allow the combination between the first end of the fixing base plate 51 and the rear bracket 4 to be released.

[0071] According to the above setting mode, the quick positioning and reliable locking of the mounting device 5 are realized through the positioning portion 511 at the first end of the fixing base plate 51 and the locking mechanism 53 at the second end. The combination of the positioning portion 511 and the rear bracket 4 ensures the accuracy of the installation reference, and the operable locking mechanism 53 provides a convenient unlocking function, so that the mounting device 5 can be stably fixed to the bracket structure and quickly disassembled. This improves the efficiency of installation and disassembly of the liquid-cooled graphics card 100, and avoids the problem of complicated operation of the traditional screw fixing mode.

[0072] Figure 3A perspective view of the mounting device provided by the embodiment of the present application is shown, wherein the lower pressing plate is removed.

[0073] In an exemplary embodiment, as shown in Figures 1 to 3 the locking mechanism 53 comprises a recess 531 and a lock tongue 532; the recess 531 is formed at the lower part of the second end of the fixed base plate 51; the lock tongue 532 is horizontally retractably arranged on the fixed base plate 51 to form a locking groove with the recess 531 in the extended state, and the locking groove is suitable for partially accommodating the cross beam 31 arranged on the front support 3 to prevent the second end of the fixed base plate 51 from moving in the vertical direction.

[0074] In detail, the recess 531 arranged at the second end of the fixed base plate 51 cooperates with the horizontally retractable lock tongue 532 to form a mechanical locking groove structure, which can accurately limit the displacement of the fixed base plate 51 in the vertical direction. By locking the cross beam 31 of the front support 3 with the locking groove, the fixation of the mounting device 5 is achieved, effectively preventing vibration or deviation during the press-fitting process of the liquid-cooled graphics card 100; at the same time, the horizontal adjustable feature of the lock tongue 532 makes the unlocking operation simple and fast, and only needs to retract the lock tongue 532 to release the height limit, which takes into account the installation stability and maintenance convenience.

[0075] In an exemplary embodiment, as shown in Figure 2 and Figure 3 the locking mechanism 53 further comprises a support table 533, a sliding part 535 and an operating part 536; the support table 533 protrudes transversely from the lower part of the second end of the fixed base plate 51, the recess 531 is formed at the lower part of the support table 533, and the support table 533 is formed with a guide sliding groove 534 extending in the longitudinal direction and penetrating through in the vertical direction; the sliding part 535 extends from the lock tongue 532 located below the support table 533 to above the guide sliding groove 534 through the guide sliding groove 534; the operating part 536 is connected to the part of the sliding part 535 extending out of the guide sliding groove 534, and is suitable for driving the sliding part 535 to move along the guide sliding groove 534 in the longitudinal direction to drive the lock tongue 532 to retract or extend relative to the recess 531.

[0076] Specifically, the transverse protruding structure of the support table 533 provides a setting base for the guide sliding groove 534 and the sliding part 535, and the guide sliding groove 534 provides a precise longitudinal motion track for the lock tongue 532, ensuring the linearity of the locking or unlocking process; the operating part 536 realizes force transmission from the remote force application to the retraction or extension of the lock tongue 532 through the rigid connection of the sliding part 535 and the lock tongue 532, so that the locking state switching can be completed by single-handed operation. This design integrates the unlocking driving mechanism and the force bearing structure in a limited space, which not only ensures the rigid connection of the mounting device 5 and the front support 3, but also simplifies the disassembly and assembly operation process, and improves the maintenance efficiency of the liquid-cooled graphics card 100.

[0077] According to an embodiment of the present invention, the operating part 536 slides against the upper wall of the support platform 533. During the sliding process, the operating part 536 always maintains surface contact with the upper wall of the support platform 533, forming a stable motion guide, effectively preventing the sliding part 535 from accidentally dislodging from the guide groove 534, and ensuring the reliability of the extension and retraction action of the locking tongue 532. This abutment structure evenly transmits the operating force to the entire support platform 533, avoiding local stress concentration, which not only enhances the vibration resistance of the locking mechanism, but also extends its service life.

[0078] Figure 4 A perspective view of the installation device provided in an embodiment of the present invention; Figure 5 This is a partially enlarged view of the positioning part combined with the rear bracket according to an embodiment of the present invention.

[0079] In one illustrative embodiment, such as Figure 4 and Figure 5 As shown, the positioning part 511 includes a positioning boss 5111 and two positioning grooves 5112; the positioning boss 5111 extends vertically and cooperates with the positioning groove 41 formed on the front bracket 3 to prevent the first end of the fixed substrate 51 from moving in the lateral direction; the two positioning grooves 5112 are symmetrically arranged on both sides of the positioning boss 5111 and cooperate with the upper edge of the positioning hole 42 provided on both sides of the positioning groove 41 to prevent the first end of the fixed substrate 51 from moving in the vertical direction.

[0080] According to the above configuration, the engagement of the positioning boss 5111 with the front bracket 3 and the positioning groove 41 effectively restricts the lateral displacement of the fixed substrate 51, while the engagement of the positioning grooves 5112 on both sides with the upper edge of the positioning hole 42 prevents the fixed substrate 51 from moving in the vertical direction. This dual limiting mechanism constrains the movement of two degrees of freedom simultaneously through a simple mechanical structure, ensuring the positional stability of the mounting device 5 during the graphics card press-fit process and effectively dispersing the impact load caused by the rebound force of the liquid cooling plug.

[0081] According to an embodiment of the present invention, the positioning groove 5112 is configured to form an inverted L-shaped channel at the first end of the fixed base plate 51, and a positioning boss 5111 is formed between two symmetrically arranged positioning grooves 5112. The two positioning grooves 5112 form a protrusion on the other side of the positioning boss 5111. A positioning groove 41 is formed on the upper edge of the front bracket 3, which abuts against the positioning boss 5111 to restrict lateral movement. The positioning holes 42 on both sides of the positioning groove 41 can accommodate the protrusion and make the upper edge of the positioning hole 42 engage in the positioning groove 5112 to achieve vertical restriction.

[0082] According to the embodiment of the present application, during the installation process, first, the positioning part 511 of the first end of the fixed base plate 51 is combined to the rear support 4, then the recessed platform 531 of the second end of the fixed base plate 51 is aligned and pressed down to the cross beam 31 of the front support 3, so that the recessed platform 531 is lapped on the cross beam 31 to form an initial positioning; then the horizontally operated lock tongue 532 is extended, and the lock slot surrounded by the end surface of the recessed platform 531 clamps the cross beam 31 in the lock slot, at this time, the cross beam 31 is in contact with the upper and lower wall surfaces of the lock slot, and the vertical displacement of the fixed base plate 51 is completely limited. When disassembling, the lock tongue 532 is reversely pushed to make it retract, the clamping of the lock tongue 532 to the cross beam 31 is released, the recessed platform 531 of the second end of the fixed base plate 51 is separated from the cross beam 31 of the front support 3, then the positioning part 511 of the first end of the fixed base plate 51 is separated from the rear support 4, and finally the fixed base plate 51 is lifted to separate the entire installation device 5 from the front support 3 and the rear support 4.

[0083] In an exemplary embodiment, as shown in Figure 3 The installation device 5 further comprises a pair of linear guide rails 54 and a pair of sliding blocks 541; the pair of linear guide rails 54 are arranged in parallel in the vertical direction on the fixed base plate 51; the pair of sliding blocks 541 are in sliding cooperation with the linear guide rails 54, and the pressing plate 52 is installed on the sliding blocks 541, and the pressing plate 52 is driven to slide downward relative to the fixed base plate 51 by applying an external force.

[0084] According to the above arrangement, through the sliding cooperation of the linear guide rails 54 and the sliding blocks 541, the precise linear motion of the pressing plate 52 in the vertical direction is realized. The problems of deflection and jamming existing in the traditional guide mechanism are effectively solved, and it is ensured that the liquid cooling graphics card 100 always maintains a vertical motion trajectory during the pressing process, so as to avoid the damage of the gold finger or the slot of the electronic device caused by the inclination. The low friction characteristic of the linear guide rail 54 makes the pressing operation more labor-saving, and the symmetrical layout of the double guide rails improves the anti-unbalanced load capacity of the mechanism, which can uniformly disperse the impact load caused by the rebound force of the liquid cooling plug, and greatly improves the stability and reliability of the installation process.

[0085] According to the embodiment of the present application, as shown in Figure 3 The pair of linear guide rails 54 are symmetrically fixed on both sides of the fixed base plate 51 by fasteners, and each guide rail is provided with a sliding block 541. The pressing plate 52 is rigidly connected to the sliding blocks 541 on both sides through the connecting plate to form a stable double sliding pair motion system. During installation, the operator applies downward pressure, the sliding blocks 541 smoothly slide along the guide rails, and drive the pressing plate 52 to move vertically downward. The linear guide rail 54 preferably adopts a ball linear guide rail, and the sliding block 541 is internally provided with a circulating ball structure to ensure smooth and non-jamming pressing action.

[0086] Figure 6 The installation device provided by the embodiment of the present application removes the structure diagram of the fixed base plate.

[0087] In an illustrative embodiment, as shown in Figure 3 and Figure 6 The mounting device 5 further comprises a reset mechanism 55, which comprises a support plate 551 and a plurality of reset springs 553. The support plate 551 is arranged on the fixed base plate 51 and is provided with a plurality of first spring seats 552. The plurality of reset springs 553 are arranged in the first spring seats 552, respectively. The lower pressing plate 52 is provided with a receiving cavity 521 for accommodating the support plate 551. The receiving cavity 521 is provided at the top with a plurality of second spring seats 522 corresponding to the first spring seats 552. The two ends of the reset spring 553 abut against the first spring seat 552 and the second spring seat 522, respectively, so that the external force overcomes the elastic force of the reset spring 553 to drive the lower pressing plate 52 to slide downward relative to the fixed base plate 51.

[0088] According to the above arrangement, the distributed arrangement of the support plate 551 and the plurality of reset springs 553 realizes the dual functions of elastic reset and pressure buffering of the lower pressing plate 52. The interval arrangement of the plurality of reset springs 553 ensures that the lower pressing plate 52 is uniformly stressed, avoiding deflection caused by single-point pressing. The spring seat structure accurately constrains the compression trajectory of the spring, preventing the spring from buckling and failing. The reset mechanism 55 enables the lower pressing plate 52 to smoothly move downward to complete the graphics card pressing under the action of the external force, and to automatically reset after the external force is removed.

[0089] According to the embodiment of the present application, as shown in Figure 3 , Figure 4 , Figures 6 to 7 The fixed base plate 51 is provided at the mounting position of the reset spring 553 with a detachable mounting cover plate 514. The mounting cover plate 514 facilitates quick disassembly. When maintenance or replacement of the reset spring 553 is required, the reset spring 553 located between the first spring seat 552 and the second spring seat 522 can be directly operated by only disassembling the mounting cover plate 514, without the need to disassemble other components. This modular design simplifies the maintenance process of the reset spring 553 and improves the maintainability and service life of the equipment.

[0091] In an illustrative embodiment, as shown in Figure 3 , Figures 6 to 8As shown, the mounting device 5 also includes a limiting mechanism 56; the limiting mechanism 56 includes: a limiting block 561, a horizontal lever 562, and a horizontal spring 563; the limiting block 561 is horizontally slidably disposed on the inner side of the fixed base plate 51; the horizontal lever 562 extends from the limiting block 561 to the outer side of the fixed base plate 51 and slides along the horizontal guide groove 512 of the fixed base plate 51; the horizontal spring 563 abuts against the limiting block 561 and the fixed base plate 51; the lower pressure plate 52 also includes a pressing part 5 23 and abutting portion 524; pressing portion 523 is located above fixed base plate 51; abutting portion 524 and pressing portion 523 are spaced apart and form limiting groove 525; wherein, when the lower pressing plate 52 is in the first position, abutting portion 524 abuts against limiting block 561 and compresses horizontal spring 563, and when the lower pressing plate 52 is in the second position, limiting block 561 is engaged in limiting groove 525 under the action of horizontal spring 563 to prevent lower pressing plate 52 from moving upward relative to fixed base plate 51.

[0092] Based on the above configuration, the automatic locking and releasing of the working position of the lower pressure plate 52 is achieved through the coordinated design of the limiting block 561, the horizontal lever 562, and the horizontal spring 563. When the lower pressure plate 52 reaches the second position (hydraulic graphics card installation complete), the limiting mechanism 56 drives the limiting block 561 to automatically engage with the limiting groove 525 via the horizontal spring 563, forming a mechanical interlock and effectively preventing the lower pressure plate 52 from rebounding due to the rebound force of the liquid cooling plug. The special structural design of the pressing part 523 and the abutting part 524 allows the lower pressure plate 52 to automatically compress the horizontal spring 563 and reserve limiting space during the pressing process. This intelligent limiting mechanism ensures both the smoothness of the installation process and the stability after installation, improving the reliability and operational efficiency of the liquid-cooled graphics card 100 installation.

[0093] Detailed, such as Figures 6 to 8 As shown, the limiting block 561 slides horizontally along the horizontal guide groove 512 of the fixed base plate 51 via the horizontal lever 562. The horizontal spring 563 is disposed between the limiting block 561 and the fixed base plate 51, providing the driving force for the horizontal movement of the limiting block 561. The top of the lower pressure plate 52 is provided with a pressing part 523, which extends above the fixed base plate 51 and cooperates with the abutment part 524 extending laterally from one side of the lower pressure plate 52 to form a limiting groove 525 structure for accommodating the limiting block 561.

[0094] According to embodiments of the present invention, such as Figure 7 and Figure 8As shown, when the lower pressing plate 52 is in the first position, the abutting portion 524 abuts against one side of the limiting block 561 and compresses the horizontal spring 563, and when an external force acts on the pressing portion 523, the lower pressing plate 52 can move in the vertical direction, and when the lower pressing plate 52 moves to the second position, the limiting groove 525 is opposite to the limiting block 561, and the limiting block 561 automatically extends into the limiting groove 525 under the restoring force of the horizontal spring 563; after the external force is removed, the limiting block 561 abuts against the upper wall of the abutting block to prevent the lower pressing plate 52 from moving upward and resetting under the driving of the resetting spring 553 of the resetting mechanism 55, thereby locking the position of the lower pressing plate 52, keeping the lower pressing plate 52 in the second position and continuously pressing the liquid cooling graphics card 100.

[0095] According to an embodiment of the present application, as shown in Figure 2 As shown, at least one fastening avoiding groove 513 is formed on the fixed base plate 51. When the lower pressing plate 52 is kept in the second position and continuously applies pressure to the liquid cooling graphics card 100, the fastening avoiding groove 513 is accurately aligned with the fastening hole on the liquid cooling graphics card 100, thereby allowing the fastening tool to operate through the avoiding groove to reliably fix and connect the liquid cooling graphics card 100 to the front bracket 3, the rear bracket 4 or the server backplane. The arrangement of the fastening avoiding groove 513 ensures the operation convenience in the installation process and ensures that the fastener can accurately align and fix the liquid cooling graphics card 100, thereby achieving a stable connection effect.

[0096] In an illustrative embodiment, as shown in Figure 3 As shown, the bottom of the lower pressing plate 52 is further provided with a flexible gasket 57.

[0097] Specifically, the elastic properties of the flexible gasket 57 can uniformly disperse the downward pressure and avoid damage to the surface of the graphics card due to excessive local pressure; at the same time, the buffering effect can effectively absorb mechanical vibration in the installation process and prevent damage to the precision components. This design also avoids the risk of static conduction through the insulation performance of the gasket, ensuring the safety and reliability of the installation process.

[0098] In an illustrative embodiment, as shown in Figures 6 to 8 As shown, the bottom of the lower pressing plate 52 is provided with at least one limiting boss 526, and the limiting boss 526 extends laterally from the lower pressing plate 52 to below the fixed base plate 51, and when the lower pressing plate 52 moves upward from the second position to the first position under the action of the resetting mechanism 55, the limiting boss 526 abuts against the bottom of the fixed base plate 51 to prevent the upward movement of the lower pressing plate 52.

[0099] The embodiment of the present application also provides an electronic device, comprising a box body, electronic devices, a liquid cooling assembly and a mounting device 5: the box body is provided with a mounting support; the electronic devices are arranged at the lower part of the mounting support; the liquid cooling assembly is arranged in the box body; and the mounting device 5 is detachably mounted on the mounting support and is suitable for mounting the liquid cooling graphics card to the interface of the liquid cooling assembly and the slot of the electronic devices.

[0101] According to the embodiment of the present application, the electronic devices include the switching backboard 1 and the power supply backboard 2, the switching backboard 1 and the power supply backboard 2 are respectively provided with a plurality of slots (such as electrical connectors) at equal intervals in the transverse direction; the liquid cooling assembly is provided with a plurality of interfaces (such as liquid cooling plugs) at equal intervals in the transverse direction; and the mounting support includes a front support 3 and a rear support 4 and is arranged at both sides of the plurality of slots and the plurality of interfaces in the longitudinal direction.

[0102] Specifically, through the modular layout design, the parallel mounting capacity of a plurality of liquid cooling graphics cards 100 in a server environment is realized. The equidistant electrical connector arrangement of the switching backboard 1 and the power supply backboard 2, in cooperation with the equidistant liquid cooling plug distribution of the liquid cooling assembly, forms a standardized transverse mounting reference; and the symmetrical arrangement of the front support 3 and the rear support 4 in the longitudinal direction provides bidirectional positioning support for the liquid cooling graphics card 100. This orthogonal layout design not only ensures that the space utilization rate is maximized when the plurality of liquid cooling graphics cards 100 are mounted, but also realizes the accurate alignment of each component through a unified spacing standard, improves the batch installation efficiency and reliability, and is particularly suitable for data center server scenarios that need to deploy a plurality of liquid cooling graphics cards 100 at the same time.

[0103] According to the embodiment of the present application, the upper end of the rear support 4 is provided with a plurality of positioning grooves 41 and positioning holes 42, the plurality of positioning grooves 41 and the plurality of positioning holes 42 are alternately distributed, and the spacing between adjacent two positioning grooves 41 and adjacent two positioning holes 42 is equal to the spacing between adjacent two electrical connectors.
