Description

Technical Field

[0001] This application relates to the field of computer accessories, and more particularly to a pressure beam and a server. Background Technology

[0002] The card-holding beam in a server is used to hold down the graphics card and prevent it from shaking during transportation or operation. The beam itself is usually a single-piece structure, and its holding height is typically not adjustable. This type of beam has poor versatility and cannot accommodate graphics cards of different heights. When the graphics card height changes, a different specification of beam needs to be replaced, increasing server production costs and maintenance complexity. Summary of the Invention

[0003] This application discloses a card-pressing beam that can adapt to graphics cards of different heights and maintain a stable pressing state on the graphics card after adjustment, thus ensuring the stability of the graphics card.

[0004] In a first aspect, embodiments of this application provide a clamping beam applied to a server, the server including a chassis and a graphics card, the clamping beam comprising: a beam body, the beam body including multiple connecting plates connected end to end, adjacent connecting plates being movably connected to form a deformable polygonal structure, the multiple connecting plates including connecting portions and clamping portions opposite each other along the thickness direction, the clamping portions being used to abut against the graphics card; a support bracket connected to the connecting portions, the support bracket being used to fix the clamping beam to the chassis; and an adjustment component disposed between the connecting portions and the clamping portions, the adjustment component being used to drive the clamping portions to move relative to the connecting portions to cause deformation of the polygonal structure.

[0005] Thus, the clamping beam provided in this embodiment has a deformable polygonal structure as its main body. The distance between the connecting part and the clamping part is adjustable. The adjustment component drives relative movement to deform the polygonal structure, thereby changing the distance and maintaining the height of the clamping beam. On the one hand, the clamping beam can be adapted to graphics cards of different heights, improving versatility; on the other hand, the frame characteristics of the polygonal structure can enhance the structural strength, ensuring the clamping stability and force balance of the clamping beam.

[0006] In some possible implementations, the multiple connecting plates are connected end to end to form a hexagonal structure.

[0007] In some possible implementations, two adjacent connecting plates are rotatably connected by a pivot.

[0008] Thus, the clamping beam provided in this application embodiment forms a hexagonal structure by connecting multiple connecting plates end to end, and uses a rotating shaft to realize the rotatable connection between adjacent connecting plates. This makes the hexagonal structure of the clamping beam subjected to balanced force during deformation, the clamping part and the connecting part always remain parallel, and the space occupied in the contracted state is small.

[0009] In some possible implementations, the adjusting component can switch between a fully extended state and a fully contracted state, wherein the extension length of the adjusting component in the fully extended state is L1, and the extension length of the adjusting component in the fully contracted state is L2, where L1 > 2L2.

[0010] Thus, the clamping beam provided in this application embodiment, by setting the extension length L1 of the adjustment component to be greater than twice the retracted length L2, allows the adjustment component to occupy less installation space when fully retracted and provide a larger height adjustment range when fully extended.

[0011] In some possible implementations, the adjustment assembly includes: a first transmission member rotatably disposed on the connecting portion, and the first transmission member being at least partially exposed outside the crossbeam body; a second transmission member including a first end and a second end along the thickness direction, the first end of the second transmission member being in transmission engagement with the first transmission member; and a third transmission member being in transmission engagement with the second end of the second transmission member, one end of the third transmission member being connected to the pressing portion, wherein the first transmission member drives the third transmission member to move along the thickness direction via the second transmission member, thereby driving the pressing portion to move.

[0012] Thus, the clamping beam provided in this embodiment forms a two-stage telescopic adjustment by sequentially engaging a first, second, and third transmission component. When the first transmission component rotates, the second and third transmission components extend or retract sequentially, and the telescopic distances of the two stages are superimposed, making the total movement distance of the third transmission component relative to the first transmission component greater than the movement distance of a single-stage telescopic structure, thereby improving the adjustment efficiency.

[0013] In some possible implementations, the adjustment assembly further includes: a first sleeve connected to the connecting portion, the second transmission member being slidably disposed within the first sleeve; a second sleeve connected to the pressing portion, the second sleeve being slidably engaged with the first sleeve, and the end of the third transmission member away from the second transmission member being disposed within the second sleeve.

[0014] Thus, the pressure beam provided in this embodiment of the application, by setting a first sleeve and a second sleeve, allows the second transmission component to be slidably disposed outside the first sleeve. The sliding fit between the first sleeve and the second sleeve guides the movement of the second transmission component and the third transmission component, preventing skewing or shaking during movement and improving the structural stability of the adjustment component.

[0015] In some possible implementations, the clamping beam further includes: a fastener, detachably disposed at the end of the beam body; a first mating part, disposed in the connecting part and located within the cavity of the polygonal structure, the first mating part including a first mating section for fastening with the fastener; and a second mating part, disposed in the clamping part and located within the cavity of the polygonal structure, the second mating part including a second mating section for fastening with the fastener, the fastener being used to extend into and fasten to the first mating section after the clamping part is adjusted to a target height.

[0016] In this way, the fastener engages with both the clamping and connecting parts via threads, enhancing the deformation resistance of the polygonal structure ends of the clamping beam. When deformation is required, simply loosen the connection between the fastener and the first mating section; the fastener will remain within the second mating section and will not fall off, thus facilitating re-tightening. This ensures structural stability and facilitates repeated adjustments.

[0017] In some possible implementations, the support bracket is fixedly connected to the connecting plate having the connecting portion.

[0018] Thus, in the embodiment of this application, the tight connection between the connecting part and the support bracket of the clamping beam does not affect the movement of the clamping part, and the clamping part can still move freely relative to the connecting part under the drive of the adjusting component.

[0019] In some possible implementations, the support bracket is slidably connected to the connecting plate on which the clamping portion is formed.

[0020] In this way, the clamping part will not tilt or twist during the movement, ensuring stable contact between the clamping part and the graphics card.

[0021] Secondly, this application provides a server, including: a chassis, the chassis including a mounting part; a graphics card disposed inside the chassis; and a card-pressing beam as described in any one of the embodiments of the first aspect of this application, the card-pressing beam being movably and detachably disposed in the mounting part.

[0022] Thus, the server provided in this application embodiment, by providing an installation part, allows the card clamping beam to be movable and detachably installed in the chassis. The movable design allows the card clamping beam to be moved away from above the graphics card when maintenance or replacement is needed, providing operating space for personnel without completely removing the beam, facilitating graphics card installation and removal. The detachable design makes maintenance and replacement of the card clamping beam itself more convenient, reducing maintenance costs. Furthermore, by employing the card clamping beam of any of the aforementioned embodiments, the server can utilize the deformable polygonal structure and adjustment components of the beam to adjust the height of the graphics card and stabilize it, ensuring the safety of the graphics card during transportation and operation.

[0023] In some possible implementations, the mounting portion extends to the card-pressing side of the graphics card, and a support member is provided on the mounting portion; a positioning groove that mates with the support member is provided on the support bracket of the card-pressing beam, and the positioning groove extends along the thickness direction of the card-pressing beam so that the card-pressing beam is assembled to the mounting portion along the thickness direction; when the card-pressing beam is assembled to the mounting portion, the support member is engaged in the positioning groove to guide and position the card-pressing beam.

[0024] Thus, the server provided in this application embodiment, by setting the cooperation between the support member and the positioning groove, allows the support member to engage with the positioning groove during the assembly of the clamping beam along the thickness direction, guiding and positioning the clamping beam. In this way, the clamping beam can move linearly along the thickness direction during assembly without skewing, ensuring that the clamping part is vertically clamped onto the clamping side of the graphics card, improving the stability and reliability of the clamping beam in fixing the graphics card.

[0025] In some possible implementations, the mounting part is further provided with a guide groove that extends along the length of the chassis and has an assembly port that communicates with the outside. The support bracket is also provided with a guide member that enters the guide groove from the assembly port. The clamping beam can be controlled to move away from the graphics card. The positioning groove separates from the support member. The clamping beam limits the guide member through the guide groove and moves away from the graphics card along the guide groove.

[0026] Thus, the server provided in this embodiment, through the cooperation of the guide groove and the guide component, allows the clamping beam to move away from the graphics card along the guide groove after the positioning groove and the support component are separated. This way, when maintenance or replacement of the graphics card is required, the operator does not need to completely remove the clamping beam; simply pushing it along the guide groove creates operating space for the graphics card, improving maintenance efficiency. Simultaneously, the limiting effect of the guide groove on the guide component ensures the clamping beam maintains a stable posture during movement, preventing deflection or wobbling and avoiding interference between the clamping beam and other components inside the chassis. After maintenance is completed, the clamping beam can be pushed back to its original position along the guide groove for reassembly, making the operation simple and quick.

[0031] 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.

Unless otherwise stated, "a plurality of" means two or more.

[0036] like Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a card-pressing beam 1, which can be applied to a server 2. The server 2 includes a chassis 50 and a graphics card 60 disposed within the chassis 50. The card-pressing beam 1 is installed inside the chassis 50 to press down on the graphics card 60, thereby preventing the graphics card 60 from shaking during transportation or operation.

[0037] The clamping beam 1 can apply downward pressure from above the graphics card 60, lateral pressure from the side of the graphics card 60, or upward support from the bottom of the graphics card 60. The specific clamping direction depends on the installation position of the clamping beam 1 within the chassis 50 and the fixing requirements of the graphics card 60. Regardless of the clamping direction, the clamping beam 1 applies a clamping force to the graphics card 60 through abutting contact.

[0038] like Figure 1 and Figure 2 As shown, the clamping crossbeam 1 includes a crossbeam body 10, a support bracket 20, and an adjustment assembly 30.

[0039] The main body of the crossbeam 10 is constructed as a frame structure, having a length direction and a thickness direction. The length direction is the direction in which the main body of the crossbeam 10 extends, and the thickness direction is perpendicular to the length direction.

[0040] As the clamping beam 1 extends along its length, the contact area with the upper surface of the graphics card 60 increases. A larger contact area results in lower pressure per unit area under the same clamping force, thus preventing deformation or damage to the graphics card 60 due to excessive local pressure. In some embodiments, the server 2 may contain multiple graphics cards 60 arranged side-by-side, with all graphics cards 60 having the same height. The clamping beam 1 extends along the arrangement direction of the multiple graphics cards 60, simultaneously abutting against multiple graphics cards 60. When the clamping beam 1 contacts the graphics card 60, the pressure distribution on the surface of each graphics card 60 is uniform, thus avoiding stress concentration. Notably, the operator only needs to adjust the height of the clamping beam 1 once to simultaneously clamp multiple graphics cards 60, eliminating the need for individual adjustments for each graphics card 60, thus simplifying the assembly process.

[0041] The main body 10 of the crossbeam includes multiple connecting plates 101 connected end-to-end. Adjacent connecting plates 101 are movably connected, allowing them to collectively form a deformable polygonal frame structure. That is, the connecting plates 101 are connected end-to-end sequentially, and adjacent connecting plates 101 can rotate relative to each other. When an external force is applied to this polygonal structure, the shape of the polygonal structure changes, i.e., the included angle between the connecting plates 101 changes. This deformable structure allows the main body 10 of the crossbeam to change its shape under external force. For example, Figure 1 The thickness of the polygonal structure of the main beam 10 shown is less than [the thickness of the polygonal structure shown]. Figure 2 The thickness of the polygonal structure of the main beam 10 shown.

[0042] The multiple connecting plates 101 include connecting portions 103 and clamping portions 102 that are opposite each other along the thickness direction. The connecting portions 103 are used to connect with the support bracket 20, and the clamping portions 102 are used to abut against the graphics card 60. When the clamping beam 1 is installed inside the server 2 chassis 50, the clamping portions 102 can abut against the upper surface of the clamping graphics card 60, applying a downward clamping force to the graphics card 60 to prevent the graphics card 60 from loosening.

[0043] Furthermore, a buffer 104 can be provided on the outside of the pressing part 102. The buffer 104 can be pressed between the graphics card 60 and the pressing part 102, which can reduce the impact force of the pressing part 102 on the graphics card 60, and increase the friction between the graphics card 60 and the pressing part 102, thereby improving the stability of the pressing.

[0044] The connecting portion 103 and the clamping portion 102 can be formed in two connecting plates 101 that are positioned opposite each other in the polygonal structure. The term "positioned opposite each other" means that when viewed along the thickness direction, the two connecting plates 101 are located on two opposite sides of the polygonal structure.

[0045] For example, when multiple connecting plates 101 form a hexagonal structure, the hexagon has six connecting plates 101, wherein the outer surfaces of two opposite connecting plates 101 are respectively the connecting portion 103 and the pressing portion 102. The outer surface of the top connecting plate 101 of the hexagon can be the connecting portion 103, the outer surface of the bottom connecting plate 101 can be the pressing portion 102, or the front connecting plate 101 can be the connecting portion 103 and the rear connecting portion 103 can be the pressing portion 102, depending on the installation orientation of the clamping beam 1.

[0046] When multiple connecting plates 101 form a quadrilateral structure, the quadrilateral has four connecting plates 101, wherein two opposite connecting plates 101 serve as connecting parts 103 and pressing parts 102, respectively. For example, the outer surface of the top connecting plate 101 of the quadrilateral can be the connecting part 103, the outer surface of the bottom connecting plate 101 can be the pressing part 102, or the front connecting plate 101 can be the connecting part 103 and the rear connecting part 103 can be the pressing part 102.

[0047] When multiple connecting plates 101 form a pentagonal structure, the pentagon has five connecting plates 101. In the pentagonal structure, one vertex and its opposite vertex can serve as the connecting part 103 and the clamping part 102, respectively. For example, one vertex of the pentagon is the clamping part 102 (i.e., the side of a connecting part 103), and the outer surface of the connecting part 103 opposite to that vertex is the clamping part 102. The asymmetry of the pentagonal structure makes the force transmission path between the connecting part 103 and the clamping part 102 different from that of a quadrilateral or hexagon, but it can still achieve the function of adjusting the distance between the clamping part 102 and the connecting part 103.

[0048] The distance between the connecting part 103 and the clamping part 102 is adjustable. Since the multiple connecting plates 101 form a deformable polygonal structure, the distance between the connecting part 103 and the clamping part 102 changes when the polygonal structure deforms. This adjustable distance allows the clamping beam 1 to adapt to graphics cards 60 of different heights. Figure 3 As shown, when the graphics card 60 is relatively tall, the distance between the connecting part 103 and the pressing part 102 can be reduced, and the thickness of the crossbeam body 10 can be decreased, thereby pressing it against the taller graphics card 60. Figure 4 As shown, when the graphics card 60 is relatively short, the distance between the connecting part 103 and the pressing part 102 can be increased, and the thickness of the crossbeam body 10 can be increased, thereby pressing it against the shorter graphics card 60. In this way, the same crossbeam body 10 can be adapted to graphics cards 60 of different heights, improving the adaptability of the crossbeam body 10.

[0049] It is worth noting that when the graphics card 60 is not needed (such as when the graphics card 60 is replaced), the thickness of the main body 10 of the crossbeam can be adjusted to the minimum. This can reduce the space occupied by the main body 10 of the crossbeam in the server 2 and reduce the risk of interference with other components in the chassis 50.

[0050] The support bracket 20 is connected to the connecting part 103. The support bracket 20 is used to fix the clamping beam 1 to the chassis 50 of the server 2. Specifically, the support bracket 20 can be fixed to the side wall of the chassis 50 by bolts, clips or other means, so the support bracket 20 provides an installation base for the clamping beam 1, so that the clamping beam 1 can be stably fixed in the chassis 50.

[0051] An adjustment assembly 30 is disposed between the connecting portion 103 and the clamping portion 102. The adjustment assembly 30 drives relative movement between the clamping portion 102 and the connecting portion 103, causing deformation of the polygonal structure of the clamping beam 1, thereby adjusting and maintaining the height of the clamping beam 1. This relative movement can be the clamping portion 102 moving relative to the connecting portion 103, the connecting portion 103 moving relative to the clamping portion 102, or both moving simultaneously. Any change in the relative position between the two will cause deformation of the polygonal structure.

[0052] In one implementation, the adjusting assembly 30 may include a screw and a nut. One end of the screw is connected to the connecting portion 103, and the nut is connected to the clamping portion 102. When the screw is rotated, the nut moves axially along the screw, causing the clamping portion 102 to move relative to the connecting portion 103. This changes the included angle between the connecting plates 101, thereby altering the shape of the polygonal structure. The deformation of the polygonal structure causes a change in the distance between the connecting portion 103 and the clamping portion 102. When the distance is adjusted to the desired distance, the operator can stop rotating the screw, using the self-locking action between the screw and the nut to maintain the distance, thus keeping the height of the clamping beam 1 stable.

[0053] In another implementation, the adjusting assembly 30 may include a gear and a rack. The gear is rotatably mounted on the connecting portion 103, and the rack is connected to and meshes with the clamping portion 102. When the gear is rotated, it drives the rack to move linearly, and the rack causes the clamping portion 102 to move relative to the connecting portion 103. When the gap is adjusted to the desired gap, the gear rotation is stopped, and the meshing resistance between the gear and the rack maintains the gap, thereby keeping the height of the clamping beam 1 stable.

[0054] It should be noted that the height adjustment process of the card clamping beam 1 is continuous. When the adjustment component 30 drives the clamping part 102 and the connecting part 103 to move relative to each other, the distance between the connecting part 103 and the clamping part 102 can be stopped at any intermediate position to achieve stepless adjustment. This allows the card clamping beam 1 to adapt to the actual height of different graphics cards 60 and avoids the matching error that may be caused by the step adjustment method.

[0055] Furthermore, since the polygonal structure is composed of multiple movable connecting plates 101, when the adjusting assembly 30 locks the gap between the clamping part 102 and the connecting part 103, the included angle between each connecting plate 101 is fixed, and the main body 10 of the crossbeam forms a stable frame. This frame structure can distribute external forces to each connecting plate 101, reduce stress concentration, and thus improve the overall structural strength of the clamping crossbeam 1. During the transportation or operation of the server 2, even if subjected to vibration or impact, the clamping crossbeam 1 can maintain a stable clamping force.

[0056] Thus, the clamping beam 1 provided in this embodiment has a deformable polygonal structure as its main body 10. The distance between the connecting part 103 and the clamping part 102 is adjustable. The adjusting component 30 drives relative movement to deform the polygonal structure, thereby changing the distance and maintaining the height of the clamping beam 1. On the one hand, the clamping beam 1 can be adapted to graphics cards 60 of different heights, improving versatility; on the other hand, the frame characteristics of the polygonal structure can enhance the structural strength and ensure the clamping stability of the clamping beam 1.

[0057] In some embodiments, the six connecting plates 101 are connected end to end to form a hexagonal structure.

[0058] Each connecting plate 101 can be evenly distributed circumferentially. When the clamping part 102 bears the reaction force of the graphics card 60, this force is transmitted to the hexagonal structure through each movable connection point. The hexagonal structure of the clamping beam 1 can disperse the concentrated load into components in multiple directions, making the load borne by each connecting plate 101 and its connection point relatively uniform. Compared with the quadrilateral structure, the stress concentration of the hexagonal structure is lower. Compared with odd-sided structures such as pentagons, the opposite sides of the hexagonal structure are parallel and symmetrical, and the force transmission path is more direct.

[0059] The unfolding range of the hexagonal structure is related to the length of each connecting plate 101. By selecting connecting plates 101 of appropriate width, a larger height adjustment range for the clamping beam 1 can be achieved. Compared with linear telescopic structures such as telescopic rods or sliding grooves, the hexagonal structure is shorter in the retracted state, which helps save internal space in the server 2.

[0060] In some embodiments, two adjacent connecting plates 101 are rotatably connected by a pivot.

[0061] The edges of two adjacent connecting plates 101 along their length direction can each be provided with connecting holes. The connecting holes of the two connecting plates 101 can be arranged alternately and avoid each other, that is, they can be arranged in a cross pattern. A rotating shaft passes through the connecting holes of the two connecting plates 101, allowing the two connecting plates 101 to rotate relative to each other around the axis of the rotating shaft. This connection method has a simple structure, is easy to assemble, and allows for flexible rotation.

[0062] The operator can drive the clamping part 102 to move closer to the connecting part 103 by operating the adjustment component 30. The six connecting plates 101 with hexagonal structure rotate around their respective axes, and the included angles between the connecting plates 101 change synchronously. During deformation, the connecting plate 101 with the clamping part 102 remains parallel to the connecting plate 101 with the connecting part 103. This parallel movement allows the clamping part 102 to make uniform contact with the upper surface of the graphics card 60, rather than line contact or point contact, thereby improving the stability and reliability of the card clamping.

[0063] Thus, the clamping beam 1 provided in this application embodiment forms a hexagonal structure by connecting multiple connecting plates 101 end to end, and uses a rotating shaft to realize the rotatable connection between adjacent connecting plates 101, so that the hexagonal structure of the clamping beam 1 is subjected to balanced force during deformation, the clamping part 102 and the connecting part 103 always remain parallel, and the space occupied in the contracted state is small.

[0064] In some embodiments, the adjusting component 30 has a fully extended state and a fully retracted state. Along the thickness direction, the fully retracted state refers to the state where the adjusting component 30 is at its shortest length. In the fully retracted state, the distance between the clamping part 102 and the connecting part 103 is the shortest, and the clamping beam 1 is the thinnest, thus suitable for graphics cards 60 with higher clamping heights. The fully extended state refers to the state where the adjusting component 30 is at its longest length. In the fully extended state, the distance between the clamping part 102 and the connecting part 103 is the longest, and the clamping beam 1 is the thickest, thus suitable for graphics cards 60 with lower clamping heights.

[0065] The extension length of the adjusting component 30 in its fully extended state is denoted as L1, and the extension length in its fully contracted state is denoted as L2. L1 is greater than twice L2, i.e., L1>2L2. This indicates that when the adjusting component 30 switches from the fully contracted state to the fully extended state, the increase in its length is greater than L2.

[0066] When L1 > 2L2, the adjusting component 30, in its fully extended state, provides a sufficient range of length variation, allowing the clamping beam 1 to accommodate graphics cards 60 with significant height differences. When the server 2 is replaced with a taller graphics card 60, there is no need to replace the clamping beam 1; the adjusting component 30 can be adjusted to its fully retracted state, causing the clamping part 102 to move upward, making room for the taller graphics card 60. When the server 2 is replaced with a shorter graphics card 60, the adjusting component 30 can be adjusted to its fully extended state, causing the clamping part 102 to extend downward to press against the shorter graphics card 60.

[0067] Thus, the clamping beam 1 provided in this application embodiment, by setting the extension length L1 of the adjustment component 30 to be more than twice the retracted length L2, allows the adjustment component 30 to occupy less installation space when fully retracted and provide a larger height adjustment range when fully extended.

[0068] In order to achieve multi-level adjustment of the adjustment component 30, in some embodiments, the adjustment component 30 includes a first transmission member 301, a second transmission member 302 and a third transmission member 303.

[0069] The first transmission member 301 is rotatably disposed on the connecting portion 103. Rotatability means that the first transmission member 301 can rotate about its own axis, but its position in the thickness direction relative to the connecting portion 103 remains fixed. The first transmission member 301 is at least partially exposed outside the beam body 10. The exposed portion allows an operator to manually rotate the first transmission member 301 without the need for additional tools. For example, the exposed end of the first transmission member 301 may be provided with a knob or handle for easy operation.

[0070] Specifically, the first transmission component 301 can be a screw, with a knurled knob on its exposed end.

[0071] The second transmission member 302 has a first end and a second end along the thickness direction. The first end and the second end are located at opposite ends of the second transmission member 302 along the thickness direction. The first end of the second transmission member 302 is in transmission engagement with the first transmission member 301 to form a first-stage telescopic adjustment. Transmission engagement means that the rotational motion of the first transmission member 301 can be converted into the linear motion of the second transmission member 302. When the first transmission member 301 rotates, the second transmission member 302 moves relative to the first transmission member 301 along the thickness direction, causing the second transmission member 302 to extend or retract from the first transmission member 301, thereby achieving the first-stage telescopic adjustment.

[0072] Specifically, the second transmission member 302 can be a lead screw with an inner cavity, and the first transmission member 301 can extend into the inner cavity of the second transmission member 302. The inner wall of the first end of the second transmission member 302 can be provided with an internal thread. The external thread of the first transmission member 301 meshes with the internal thread to form a threaded transmission engagement.

[0073] The third transmission member 303 is in transmission engagement with the second end of the second transmission member 302. One end of the third transmission member 303 is connected to the pressing part 102. The transmission engagement between the third transmission member 303 and the second transmission member 302 forms a two-stage telescopic adjustment. When the second transmission member 302 moves, it drives the third transmission member 303 to move relative to it. This movement causes the third transmission member 303 to extend or retract from the second transmission member 302, thereby achieving the two-stage telescopic adjustment.

[0074] Specifically, the inner wall of the second end of the second transmission member 302 may be provided with an internal thread, and the third transmission member 303 is provided with an external thread. The third transmission member 303 extends into the inner cavity of the second transmission member 302, forming a threaded transmission engagement. When the second transmission member 302 rotates under the drive of the first transmission member 301, the third transmission member 303 moves axially along the second transmission member 302. Since one end of the third transmission member 303 is connected to the pressing part 102, the movement of the third transmission member 303 drives the pressing part 102 to move.

[0075] In practical applications, when the first transmission component 301 rotates under the operator's control, it drives the second transmission component 302 to move relative to it. Simultaneously, the second transmission component 302 drives the third transmission component 303 to move relative to it. The movement distances of the two stages of extension and retraction are superimposed, making the total movement distance of the third transmission component 303 relative to the first transmission component 301 equal to the sum of the first and second stage extension and retraction distances. Therefore, when the first transmission component 301 rotates the same number of times, a two-stage extension and retraction structure can achieve a greater movement distance than a single-stage extension and retraction structure.

[0076] For example, the first-stage extension distance of the first transmission member 301 can be 1 mm per revolution, and the second-stage extension distance can also be 1 mm. After the two stages of extension are superimposed, the total movement distance of the third transmission member 303 relative to the first transmission member 301 is 2 mm. If a single-stage extension structure is used, the movement distance of the first transmission member 301 per revolution is only 1 mm. It can be seen that two-stage extension can achieve a faster extension speed with the same number of revolutions, or reduce the number of revolutions with the same extension distance, thereby improving adjustment efficiency.

[0077] When the adjusting assembly 30 is in the fully retracted state, the second transmission member 302 can move upwards, and the third transmission member 303 can be completely retracted into the second transmission member 302. At this time, the total length of the adjusting assembly 30 is approximately the length of the first transmission member 301. When the adjusting assembly 30 switches to the fully extended state, the second transmission member 302 extends completely relative to the first transmission member 301, and the third transmission member 303 extends completely from the second transmission member 302. At this time, the total length of the adjusting assembly 30 is equal to the length of the first transmission member 301 plus the extended length of the second transmission member 302 plus the extended length of the third transmission member 303. If the lengths of the three transmission members are equal, then the length of the adjusting assembly 30 in the fully extended state is three times its length in the fully retracted state.

[0078] Thus, the clamping beam 1 provided in this embodiment of the application forms a two-stage telescopic adjustment by sequentially engaging a first transmission member 301, a second transmission member 302, and a third transmission member 303. When the first transmission member 301 rotates, the second transmission member 302 and the third transmission member 303 extend or retract sequentially. The telescopic distances of the two stages are superimposed, making the total moving distance of the third transmission member 303 relative to the first transmission member 301 greater than the moving distance of a single-stage telescopic structure, thereby improving the adjustment efficiency.

[0079] like Figure 5 As shown, in some embodiments, the adjusting assembly 30 further includes a first sleeve 304. The first sleeve 304 is connected to the connecting portion 103.

[0080] The first sleeve 304 can be a hollow tubular component with an internal receiving cavity extending along its thickness direction. One end of the first sleeve 304 is fixedly connected to the connecting part 103, and the other end is an open end extending towards the pressing part 102. The second transmission member 302 is located inside the first sleeve 304 and can extend out of the first sleeve 304 through its open end.

[0081] The second transmission member 302 is slidably disposed within the first sleeve member 304. That is, a sliding fit is formed between the outer wall of the second transmission member 302 and the inner wall of the first sleeve member 304, allowing the second transmission member 302 to move within the first sleeve member 304 along its thickness direction. The first sleeve member 304 guides the movement of the second transmission member 302, preventing it from tilting or wobbling during movement.

[0082] like Figure 5 As shown, in some embodiments, the adjusting assembly 30 further includes a second sleeve 305. The second sleeve 305 is connected to the clamping part 102.

[0083] The second cylindrical component 305 can also be a hollow structure, with a channel extending along the thickness direction inside. One end of the second cylindrical component 305 is fixed to the pressing part 102, and the other end extends toward the connecting part 103. The inner diameter of the second cylindrical component 305 can be larger than the outer diameter of the first cylindrical component 304.

[0084] The second cylindrical component 305 is slidably fitted with the first cylindrical component 304. The outer wall of the first cylindrical component 304 is in contact with the inner wall of the second cylindrical component 305, and the second cylindrical component 305 can move outside the first cylindrical component 304 along the thickness direction. The first cylindrical component 304 guides the movement of the second cylindrical component 305, causing the second cylindrical component 305 to move linearly along the thickness direction.

[0085] The third transmission member 303, with its end away from the second transmission member 302, is disposed within the second sleeve 305. One end of the third transmission member 303 is in transmission engagement with the second transmission member 302, and the other end of the third transmission member 303 is located inside the second sleeve 305 and connected to the pressing part 102 through the second sleeve 305. The second sleeve 305 provides a space for accommodating the third transmission member 303.

[0086] Thus, the pressure beam 1 provided in this embodiment of the application, by setting a first sleeve 304 and a second sleeve 305, allows the second transmission member 302 to be slidably disposed outside the first sleeve 304. The sliding fit between the first sleeve 304 and the second sleeve 305 guides the movement of the second transmission member 302 and the third transmission member 303, preventing skewing or shaking during movement and improving the structural stability of the adjustment component 30.

[0087] In the above embodiment, the adjustment component 30 can be located at the middle position along the length direction of the crossbeam body 10. The middle position can reduce the bending moment borne by the adjustment component 30, which is beneficial to improving the service life and locking reliability of the adjustment component 30.

[0088] In order to maintain the structural stability of the polygonal structure at the end of the clamping beam 1, in some embodiments, the clamping beam 1 further includes two sets of end shape retaining components 40. The end shape retaining components 40 can be respectively disposed at both ends of the beam body 10 along the length direction to keep the polygonal structure of the beam body 10 from deforming at the end.

[0089] The end shape retaining component 40 is used to fix the shape of both ends of the crossbeam body 10 after the adjusting component 30 adjusts the clamping part 102 to the target height, that is, after the polygonal structure formed by the multiple connecting plates 101 has deformed. At this time, the polygonal structure has been deformed to the target shape, but since the crossbeam body 10 has an extended length, its ends may still deform under force. The end shape retaining component 40 is used to lock the polygonal structure at the end parts of the crossbeam body 10 that are prone to deformation, especially in the ring of multiple graphics cards 60, to maintain consistent clamping of multiple graphics cards 60.

[0090] In some embodiments, the end shape retaining component 40 may include a fastener 401, a first mating portion 402, and a second mating portion 403.

[0091] Fastener 401 is detachably mounted on the end of the crossbeam body 10. Fastener 401 can be a bolt, screw, or pin, or other fastening component. Fastener 401 can be inserted into or removed from the end of the crossbeam body 10 along the thickness direction, facilitating assembly and maintenance.

[0092] The first mating part 402 is disposed on the connecting part 103 and located within the cavity of the polygonal structure. The cavity of the polygonal structure refers to the internal space enclosed by multiple connecting plates 101. The first mating part 402 includes a first mating section for fastening with the fastener 401. The first mating section may be a threaded hole, a groove, or a pin hole, etc., which can form a detachable fixed connection with the fastener 401.

[0093] The second mating part 403 is disposed on the clamping part 102 and located within the cavity of the polygonal structure. The second mating part 403 is also located within the internal cavity of the polygonal structure. The second mating part 403 includes a second mating section for fastening with the fastener 401. The second mating section can have a threaded hole or a slot, etc. The second mating section and the fastener 401 can have a clearance fit, a threaded fit, or an interference fit, depending on the design requirements.

[0094] After the adjusting assembly 30 completes the thickness adjustment of the crossbeam body 10, the operator inserts the fastener 401 from the end of the crossbeam body 10. The fastener 401 first passes through the threaded hole of the second mating section, and then continues to extend into the threaded hole of the first mating section. The operator rotates the fastener 401 so that the fastener 401 simultaneously engages with the threads of both the second and first mating sections. At this time, the fastener 401 is connected to the connecting part 103 and the clamping part 102 respectively, and the two ends of the polygonal structure are fixed, maintaining the end shape.

[0095] The adjusting component 30 controls the dimensions in the thickness direction, while the end shape maintaining component 40 controls the shape stability of both ends of the crossbeam body 10 in the length direction. When both act simultaneously, the clamping crossbeam 1 is constrained in both the thickness and length directions, and the polygonal structure of the crossbeam body 10 reduces the probability of twisting or deformation due to external forces. This dual structural constraint allows the clamping crossbeam 1 to maintain a stable clamping force even under vibration during server 2 transportation or high-load operating environments, ensuring the fixed reliability of the graphics card 60.

[0096] When the height of the clamping beam 1 needs to be readjusted, the operator simply loosens the fastener 401 from the first mating section, causing the fastener 401 to disengage from the first mating section. Since the fastener 401 remains threadedly engaged with the second mating section, it will not come out of the second mating section, preventing it from falling or being lost. The operator can then reoperate the adjusting component 30 to move the clamping part 102 to the new target height, and then screw the fastener 401 back into the first mating section to complete the locking process.

[0097] Thus, the fastener 401 engages with both the clamping part 102 and the connecting part 103 via threads, enhancing the deformation resistance of the polygonal structure end of the clamping beam 1. When deformation is required, simply loosen the connection between the fastener 401 and the first mating section; the fastener 401 will remain within the second mating section and will not fall off, facilitating re-tightening. This ensures structural stability and facilitates repeated adjustments.

[0098] like Figure 2 As shown, in some embodiments, the support bracket 20 is fixedly connected to the connecting plate 101 having the connecting portion 103.

[0099] Specifically, in one implementation, the support bracket 20 is provided with mounting holes 201. The support bracket 20 is used to fix the clamping beam 1 to the chassis 50 of the server 2. The mounting holes 201 are formed on the support bracket 20 for connection with the connecting part 103.

[0100] A fastener is provided on the connecting plate 101, which has a connecting portion 103. The connecting portion 103 is a polygonal structure for connecting to the support bracket 20. The fastener is provided on the connecting plate 101 and can be a fastening part such as a bolt, rivet, or pin. The fastener extends from the connecting portion 103 toward the support bracket 20, or is provided on the side of the connecting portion 103 facing the support bracket 20.

[0101] The fastener is securely connected to the mounting hole 201. The fastener passes through the mounting hole 201 and is fixedly connected to the mounting hole 201 by means of threaded fit, interference fit, or snap-fit. When it is necessary to disassemble the clamping beam 1, the operator only needs to loosen the connection between the fastener and the mounting hole 201, so that the connecting part 103 is separated from the support bracket 20, and the entire beam body 10 can be removed from the support bracket 20.

[0102] In other embodiments, the support bracket 20 and the connecting plate 101 can also be fixedly connected by welding, integral molding, bonding or riveting, as long as the connection strength and positional accuracy requirements between the two can be met.

[0103] Thus, the clamping beam 1 provided in this embodiment of the application, by providing a fixing member and a mounting hole 201, securely connects the connecting part 103 to the support bracket 20, keeping the connecting part 103 fixed relative to the support bracket 20. In this way, the connecting part 103, as the fixed end of the beam body 10, provides a stable support reference for the movement of the clamping part 102. At the same time, the secure connection between the connecting part 103 and the support bracket 20 does not affect the movement of the clamping part 102; the clamping part 102 can still move freely relative to the connecting part 103 under the drive of the adjusting component 30.

[0104] like Figure 2 As shown, in some embodiments, the support bracket 20 is slidably connected to the connecting plate having the clamping portion 102.

[0105] Specifically, in one implementation, the support bracket 20 may be provided with a slide groove 205. The slide groove extends along the thickness direction, and the clamping part 102 may be provided with a sliding member, which slides within the slide groove 205. When the adjusting component 30 drives the clamping part 102 to move, the sliding member slides within the slide groove 205. The slide groove 205 guides and limits the sliding member, ensuring that the sliding member can only move along the thickness direction and does not deviate in other directions. In this way, the clamping part 102 will not tilt or twist during movement, ensuring stable contact between the clamping part 102 and the graphics card 60.

[0106] In some embodiments, scale markings 206 are provided on both sides of the slide 205. The spacing of the scale markings 206 can be on the order of millimeters. For example, a scale line is provided every 1 millimeter, and the corresponding scale value is marked every 5 millimeters or 10 millimeters.

[0107] When the operator rotates the adjustment component 30 to drive the clamping part 102 to move, the sliding member connected to the clamping part 102 slides within the slide groove 205. The operator can observe the scale markings corresponding to the sliding member to read the current position of the clamping part 102. Through the scale markings, the operator can control the moving distance of the clamping part 102 and adjust the clamping part 102 to the target height.

[0108] For example, when an operator needs to increase the height of the clamping beam 1 by 5 mm, they can operate the adjustment component 30 while observing the movement of the slider on the scale mark 206. When the slider moves from the current scale mark to the scale mark after the 5 mm increase, the operation of the adjustment component 30 is stopped, completing the thickness adjustment of the clamping beam 1. The adjustment process does not require external measuring tools; precise adjustment can be achieved through the scale mark 206.

[0109] In other embodiments, the support bracket 20 and the connecting plate 101 can also be slidably connected by means of guide rail and slider cooperation, linear bearing and guide shaft cooperation, etc., as long as it can ensure that the two slide relatively smoothly in a preset direction.

[0110] Thus, by setting millimeter-level scale markings 206 on both sides of the slide groove 205, operators can read the movement distance of the clamping part 102, achieving visual adjustment. This avoids adjustments based on experience or repeated trial and error, improving adjustment efficiency and accuracy. At the same time, the scale markings 206 are integrated into the support bracket 20, occupying no extra space and resulting in a compact structure. Operators can complete precise adjustments without carrying measuring tools, lowering the operational threshold and facilitating on-site maintenance and rapid deployment.

[0111] like Figure 3 , Figure 4 and Figure 6 As shown, a second aspect of this application also provides a server 2, which includes a chassis 50, a graphics card 60, and a card-pressing beam 1 provided in any of the first aspects of the embodiment. Since the server 2 includes the card-pressing beam 1, the beneficial effects of the card-pressing beam 1 will not be elaborated further.

[0112] The chassis 50 is the outer shell of the server 2, used to house and protect the various components inside the server 2. The chassis 50 includes a mounting section 501. The mounting section 501 is used to mount the structure of the clamping beam 1.

[0113] like Figure 6As shown, the mounting part 501 can be located on the side wall of the chassis 50, or on the top or bottom wall of the chassis 50 as needed. The specific location depends on the installation direction and pressing method of the clamping beam 1. For example, when the clamping beam 1 clamps the graphics card 60 from above, the mounting part 501 can be located on the upper part of the side wall of the chassis 50. When the clamping beam 1 supports the graphics card 60 from the bottom, the mounting part 501 can be located on the bottom wall of the chassis 50.

[0114] like Figure 3 , Figure 4 and Figure 6 As shown, graphics card 60 is housed within chassis 50. Graphics card 60 is an expansion card responsible for graphics processing in server 2, and it connects to the motherboard's PCIe slot via gold fingers. There can be one or more graphics cards 60, and multiple graphics cards 60 can be arranged side-by-side within chassis 50. The card-holding beam 1 is used to hold the graphics card 60 in place, preventing it from shaking during transportation or operation.

[0115] like Figure 6 As shown, the clamping beam 1 is movably and detachably mounted on the mounting section 501. "Movable" means that the clamping beam 1 can move on the mounting section 501, for example, moving along the length of the chassis 50 to adjust the clamping position. This allows it to be moved above the graphics card 60 to apply clamping force when needed. When the graphics card 60 needs to be removed or replaced, the clamping beam 1 can be moved away from above the graphics card 60, opening up the space above the graphics card 60 for easy access without completely removing the clamping beam 1. "Detachable" means that the clamping beam 1 can be removed from the mounting section 501 for easy maintenance or replacement. Figure 6 The diagram shown is a schematic of the card clamping beam 1 being moved out of the card clamping side of the graphics card.

[0116] Thus, the server 2 provided in this embodiment of the application, by setting the mounting part 501, allows the card clamping beam 1 to be movably and detachably installed on the chassis 50. The movable design allows the card clamping beam 1 to be moved away from above the graphics card 60 when maintenance or replacement is required, making room for operators without having to completely remove the card clamping beam 1, facilitating the installation and removal of the graphics card 60. The detachable design makes the maintenance and replacement of the card clamping beam 1 itself more convenient, reducing maintenance costs. At the same time, by using the card clamping beam 1 of any of the aforementioned embodiments, the server 2 can utilize the deformable polygonal structure and adjustment component 30 of the card clamping beam 1 to adjust the height of the graphics card 60 and stabilize the card clamping, ensuring the safety of the graphics card 60 during transportation and operation.

[0117] In some embodiments, such as Figure 6As shown, part of the mounting section 501 extends to the card clamping side of the graphics card 60. The card clamping side can be the top, side, or bottom of the graphics card 60, depending on the direction of the graphics card 60 toward the card clamping beam 1.

[0118] In some embodiments, such as Figure 6 As shown, a support member 5011 is provided on the mounting part 501. The support member 5011 can be a protruding cylinder, block, or pin, etc., used to cooperate with the clamping beam 1 to provide support and guidance.

[0119] In some embodiments, such as Figure 2 As shown, the support bracket 20 of the clamping beam 1 is provided with a positioning groove 202 that mates with the support member 5011. The positioning groove 202 extends along the thickness direction of the clamping beam 1. The thickness direction refers to the direction in which the clamping part 102 of the clamping beam 1 points towards the graphics card 60, and it is also the direction in which the height of the clamping beam 1 is adjusted. The length direction of the positioning groove 202 is consistent with the thickness direction, so that the positioning groove 202 can accommodate the support member 5011 along the thickness direction.

[0120] The clamping beam 1 is assembled to the mounting part 501 along the thickness direction. During assembly, the operator presses the clamping beam 1 down along the thickness direction, aligning the support member 5011 with the opening of the positioning groove 202. As the clamping beam 1 moves, the support member 5011 gradually enters the positioning groove 202.

[0121] When the clamping beam 1 is assembled to the mounting section 501, the support member 5011 engages with the positioning groove 202. The outer wall of the support member 5011 contacts the inner wall of the positioning groove 202, forming a sliding fit. The support member 5011 constrains the positioning groove 202, limiting the movement of the clamping beam 1 in directions perpendicular to the thickness direction. Simultaneously, the engagement between the support member 5011 and the positioning groove 202 provides guidance for the assembly of the clamping beam 1, enabling it to move linearly along a direction close to the graphics card 60, accurately reaching the installation position.

[0122] Thus, the server 2 provided in this embodiment of the application, through the cooperation between the support member 5011 and the positioning groove 202, allows the support member 5011 to engage with the positioning groove 202 during assembly of the clamping beam 1 along the thickness direction, thereby guiding and positioning the clamping beam 1. In this way, the clamping beam 1 can move linearly along the thickness direction during assembly without skewing, ensuring that the clamping part 102 is vertically clamped onto the clamping side of the graphics card 60, improving the stability and reliability of the clamping beam 1 in fixing the graphics card 60.

[0123] In some embodiments, such as Figure 6As shown, the mounting section 501 is also provided with a guide groove 5022. The guide groove 5022 extends along the length direction of the chassis 50. The length direction of the chassis 50 can be the direction in which the gold finger end of the graphics card 60 points to the tail end. The guide groove 5022 is provided with an assembly port 5023 communicating with the outside. The assembly port 5023 is located at one end of the guide groove 5022 to allow the guide member 203 to enter the guide groove 5022.

[0124] like Figure 2 As shown, a guide member 203 is also provided on the support bracket 20. The guide member 203 can be a structure such as a protrusion, slider, or pin, extending outward from the surface of the support bracket 20. The shape of the guide member 203 matches the guide groove 5022, allowing it to slide within the guide groove 5022.

[0125] The guide component 203 enters the guide groove 5022 from the assembly port 5023. During assembly, the operator first aligns the guide component 203 with the assembly port 5023, and then pushes the guide component 203 into the guide groove 5022. The guide groove 5022 has a certain height, so as not to affect the sinking fit between the positioning groove 202 and the support component 5011. The support bracket 20 of the clamping beam 1 is provided with a hand-tightening screw 204 for fixing to the chassis 50. When it is necessary to fix the clamping beam 1, the hand-tightening screw 204 can be tightened to fix 11 to the chassis 50.

[0126] When you need to replace your graphics card (60), such as Figure 6 As shown, the operator can loosen the hand screw 204 and then lift the clamping beam 1. The clamping beam 1 can be moved in a controlled manner away from the graphics card 60, and the positioning groove 202 separates from the support member 5011. At this time, the guide member 203 remains within the guide groove 5022, which restricts the movement of the guide member 203 along the length of the chassis 50. The operator pushes the clamping beam 1 along the guide groove 5022, causing the clamping beam 1 to move away from the clamping side of the graphics card 60 and to the side of the graphics card 60 area. Due to the limiting effect of the guide groove 5022, the clamping beam 1 will not deflect or wobble during the movement and will always maintain a stable posture. Then, the clamping beam 1 is moved away from the graphics card 60. As the clamping beam 1 moves, it moves away from the clamping side of the graphics card 60, exposing the graphics card 60 area. The operator can then remove the graphics card 60 for maintenance or replacement.

[0127] After maintenance, the operator can push the clamping beam 1 back to the clamping side of the graphics card 60 along the guide groove 5022, and then move the clamping beam 1 along the thickness direction so that the support 5011 is inserted into the positioning groove 202. Finally, tighten the hand screw 204.

[0128] Thus, the server 2 provided in this embodiment, through the cooperation of the guide groove 5022 and the guide member 203, allows the clamping beam 1 to move away from the graphics card 60 along the guide groove 5022 after it separates from the support member 5011 in the positioning groove 202. This way, when maintenance or replacement of the graphics card 60 is required, the operator does not need to completely remove the clamping beam 1; simply pushing it away along the guide groove 5022 creates operating space for the graphics card 60, improving maintenance efficiency. Simultaneously, the limiting effect of the guide groove 5022 on the guide member 203 ensures that the clamping beam 1 maintains a stable posture during movement, preventing deflection or wobbling and avoiding interference between the clamping beam 1 and other components inside the chassis 50. After maintenance is completed, the clamping beam 1 can be pushed back to its original position along the guide groove 5022 for reassembly, making the operation simple and quick.

[0129] 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.
