A server board pull-out device and computer equipment

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411188201.9, filed on August 28, 2024, entitled "A Server Board Pull-out Device and Computer Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of computer server technology, specifically relating to a server board pull-out device and computer equipment. Background Technology

[0004] As a form of computer, servers provide computing or application services to other client machines or large devices on a network, undertaking critical tasks such as data storage, forwarding, and publishing. In recent years, with the continuous improvement of server performance, the height, size, and weight of the components and heat sinks placed on server motherboards and GPUs (graphics processing units) have also been increasing.

[0005] Therefore, a lifting mechanism is required on the server boards to facilitate assembly and disassembly, enabling the boards to be lifted as a whole, reducing operational difficulty and the risk of damage to components. Server board lifting mechanisms typically use a one-piece molded structure. Once assembled, the height and width are often fixed, and a certain amount of hand grip space needs to be designed on the lifting handle for easy maneuvering. The area projected by the handle on the board needs to be height-restricted to prevent component placement, limiting component layout on the board. Furthermore, the routing of cables inside the chassis must completely avoid the handle area, causing difficulties in cable management.

[0006] In related technologies, the handheld space on the server board lifting device occupies a certain amount of chassis space, making it impossible to provide more space for placing components inside the server chassis. Summary of the Invention

[0032] In some embodiments of this application, a cover plate and fasteners are also included;

[0033] The cover plate is fixed to the end of the bracket body, the first snap-fit ​​protrusion faces the cover plate from the side away from the compression spring, and the fastener is inserted between the end of the cover plate and the bracket body.

[0042] In some embodiments of this application, the pressing component has a cylindrical structure, with the upper end of the pressing component closed and equipped with a button, and the lower end of the pressing component having an opening for connecting the second rotating shaft, the second torsion spring and the cam assembly.

[0043] On the other hand, embodiments of this application also provide a computer device including the server board pull-out device of any of the above.

[0044] In this embodiment, the server board lifting device includes a bracket assembly, a gripping plate, a first rotating shaft, a first torsion spring, and a locking element. The bracket assembly is the main body of the lifting device, providing support and connection, and is suitable for fixing the server board. It can be designed as a separate structure or an integrated structure. The gripping plate, also known as a handheld wing plate, is used by the operator to grip and lift the board. The first rotating shaft can be a pin, connected to the bracket assembly. The gripping plate is connected to the first rotating shaft, allowing the gripping plate to rotate relative to the bracket assembly around the first rotating shaft. There are two implementation methods: the first is that the first rotating shaft is fixedly connected to the bracket assembly, and the gripping plate is rotatably connected to the first rotating shaft; the second is that the first rotating shaft is rotatably connected to the bracket assembly, and the gripping plate is fixedly connected to the first rotating shaft. One end of the locking element is fixed to the protruding shaft of the bracket assembly, and the other end is adapted to engage with or disengage from the mounting protrusion on the gripping plate. When the other end of the locking element engages with the mounting protrusion on the grip plate, the grip plate is close to the bracket assembly and is in a folded state. When the other end of the locking element disengages from the mounting protrusion on the grip plate, the grip plate moves away from the bracket assembly and is in an unfolded state. A first torsion spring passes through the first rotating shaft, with one end connected to the bracket assembly and the other end connected to the grip plate. In the initial state, the other end of the locking element engages with the mounting protrusion on the grip plate, causing the grip plate to be close to the bracket assembly and folded, preventing the grip plate from occupying space inside the chassis when not in use. At this time, the first torsion spring is in a deformed state and possesses a certain elastic potential energy. When it is necessary to lift and remove a server board, the operator pulls the other end of the locking mechanism, causing it to disengage from the mounting protrusion on the grip plate. This releases the elastic potential energy of the first torsion spring, and under the action of the elastic force, the grip plate quickly opens away from the side of the bracket assembly until the first torsion spring returns to its natural state, at which point the grip plate is fully extended. The operator can then lift the server board using the grip plate. Therefore, the server board lifting device provided in this embodiment, when not in use, has the grip plate folded and close to the bracket assembly, avoiding occupying chassis space and allowing for more space inside the server for component placement. When in use, pulling the other end of the locking mechanism opens the grip plate, facilitating the operator's lifting of the server board. Attached Figure Description

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0057] The server board lifting device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0058] In some embodiments of this application, referring to Figures 1, 2, and 4, the server board card lifting device provided in this application includes a bracket assembly 1, a gripping plate 2, a first rotating shaft 3, a first torsion spring 4, and a locking member 5. The first rotating shaft 3 is connected to the bracket assembly 1, and the gripping plate 2 is rotatably connected to the bracket assembly 1 through the first rotating shaft 3. The gripping plate 2 is provided with a mounting protrusion 21. One end of the locking member 5 is rotatably connected to the bracket assembly 1, and the bracket assembly 1 is adapted to fix the server board card. The other end of the locking member 5 is adapted to engage with or disengage from the mounting protrusion 21, so that the gripping plate 2 is in a folded state or an unfolded state. The first torsion spring 4 passes through the first rotating shaft 3. One end of the first torsion spring 4 is connected to the bracket assembly 1, and the other end is connected to the gripping plate 2. When the gripping plate 2 is in a folded state, the first torsion spring 4 is in a deformed state.

[0059] Specifically, Figure 4 shows an exploded view of the server board lifting device provided in this application embodiment, and Figures 1 and 2 respectively show structural schematic diagrams of the server board lifting device provided in this application embodiment in its unfolded and folded states. The server board lifting device provided in this application embodiment includes a bracket assembly 1, a gripping plate 2, a first rotating shaft 3, a first torsion spring 4, and a locking fastener 5. The bracket assembly 1 is the main body of the lifting device, serving as a support device and connecting different components, used to fix the server board.

[0060] It primarily bears the weight of the circuit boards. The bracket assembly 1 can be designed as a separate or integrated structure. When designed as an integrated structure, the structural strength is greater; when designed as a separate structure, the relative sliding between the separate components allows for height adjustment, in addition to switching between unfolded and folded states of the grip plate. The grip plate 2, also known as a handheld wing plate, is used by the operator to grip and lift for disassembling the server circuit boards. The first rotating shaft 3 can be a pin connected to the bracket assembly 1, and the gripping plate 2 is connected to the first rotating shaft 3, allowing the gripping plate 2 to rotate relative to the bracket assembly 1 around the first rotating shaft 3. This function can be implemented in two ways: First, the first rotating shaft 3 is rotatably connected to the bracket assembly 1, and the gripping plate 2 is fixedly connected to the first rotating shaft 3. When the first rotating shaft 3 is driven to rotate, it causes the gripping plate 2 to rotate relative to the bracket assembly 1. Second, the first rotating shaft 3 is fixedly connected to the bracket assembly 1, and the gripping plate 2 has a rotating hole through which the first rotating shaft 3 passes. The first rotating shaft 3 is rotatably connected to the gripping plate 2, and while the first rotating shaft 3 remains fixed, the gripping plate 2 is driven to rotate relative to the bracket assembly 1. This embodiment uses the second method, but it is not limited to this; those skilled in the art can flexibly choose the appropriate method based on actual conditions. The locking element 5 is strip-shaped or hook-shaped, with snap-fit ​​structures at both ends. One end is fixed to the protrusion shaft 125 of the bracket assembly 1, allowing the other end to rotate around the protrusion shaft 125. The other end is suitable for engaging or disengaging from the mounting protrusion 21 on the grip plate 2. When the hook-shaped snap-fit ​​structure at the other end of the locking element 5 engages with the mounting protrusion 21 on the grip plate 2, the locking element 5 is limited and fixed by the mounting protrusion 21 on the grip plate 2. At this time, the grip plate 2 is close to the side wall of the bracket assembly 1 and is in a folded state. When the operator moves the other end of the locking element 5, causing it to disengage from the mounting protrusion 21 on the grip plate 2, the other end of the grip plate 2 quickly breaks free from the limiting and fixing effect of the locking element 5 and moves away from the bracket assembly 1 until the grip plate 2 is unfolded, providing a gripping position for the operator to easily disassemble the server board. The first torsion spring 4 is a helical spring. Its principle is that the two ends of the torsion spring are fixed to other components. When an external force is applied, causing the other components to rotate around the center of the spring, the torsion spring accumulates elastic potential energy. Once the external force is removed, a torque or rotational force is generated, which can pull the other components back to their initial position. The first torsion spring 4 is mounted on the first rotating shaft 3 for better fixation and limitation. Its rotation center is the first rotating shaft 3. One end of the first torsion spring 4 is fixedly connected to the bracket assembly 1, and the other end is fixedly connected to the grip plate 2.

[0061] In some embodiments, as shown in Figure 2, in the initial state, the other end of the locking member 5 is engaged and fixed with the mounting protrusion 21 on the grip plate 2, so that the grip plate 2 is close to the side wall of the bracket assembly 1. The grip plate 2 is in a folded state, which can prevent the grip plate from occupying the space inside the chassis when not in use. At this time, the first torsion spring 4 is in a deformed state and has a certain elastic potential energy. However, since the grip plate 2 is limited and fixed, the first torsion spring 4 cannot generate torque. As shown in Figures 2 to 1, when the server board needs to be disassembled and moved using the lifting device, the operator pulls down the other end of the locking member 5, causing the locking structure at the other end of the locking member 5 to disengage from the mounting protrusion 21 on the gripping plate 2. At this time, the elastic potential energy of the first torsion spring 4 is released. Under the action of rotational force, the first torsion spring 4 drives the gripping plate 2 to rotate relative to the bracket assembly 1 around the first rotating shaft 3, that is, to rotate clockwise away from the side wall of the bracket assembly 1 as shown in Figures 2 and 1, until the first torsion spring 4 is in its natural state and the rotational force disappears. At this time, the gripping plate 2 rotates to a state perpendicular to the side wall of the bracket assembly 1 and is fully unfolded, providing a hand gripping position for the operator. The operator can lift and disassemble the server board through the gripping plate 2.

[0062] In addition, a limiting plate can be set above the bracket assembly 1. The limiting plate protrudes from the cover plate 91 to prevent the gripping plate 2 from being too high or even vertical when the rotational force generated by the first torsion spring 4 is too large, which would affect the operator's gripping. The positions of the limiting plate and the gripping plate 2 correspond one-to-one. The limiting plate is perpendicular to the side wall of the bracket assembly 1. When the gripping plate 2 rotates to be perpendicular to the side wall of the bracket assembly 1, it will be limited by the limiting plate and cannot continue to rotate. In order to avoid occupying too much space in the server chassis, the length and width of the limiting plate are smaller than those of the gripping plate.

[0063] The server board lifting device provided in this application embodiment, when not in use, has its grip plate locked in a folded state against the bracket assembly by the locking mechanism, avoiding occupying chassis space and allowing more space for component placement inside the server. In use, the operator moves the other end of the locking mechanism, and the rotational force of the first torsion spring opens the grip plate, facilitating the lifting and removal of the server board. This achieves adjustable folding of the handle position. It solves the problem in related technologies where the lifting device's handheld space occupies too much chassis space and affects cable management, thus making full use of the space inside the server chassis and improving the maintainability of the server.

[0064] In some embodiments of this application, referring to Figures 4 and 5, the assembly further includes a pressing component 61, a cam component 62, a second torsion spring 63, and a second rotating shaft 64. The bracket assembly 1 includes a bracket body 11 and a base 12. The base 12 has a first cavity 121, and the inner wall of the first cavity 121 is provided with a slot 122. The bracket body 11 is slidably connected to the first cavity 121. The bracket body 11 has a second cavity 111, and the side wall of the bracket body 11 has a through hole 112 communicating with the second cavity 111. The pressing component 61 extends at least partially into the second cavity 111 and is slidably connected to the bracket body 11. The cam component 62 and the second torsion spring 63 are located in... Inside the pressing assembly 61, the second rotating shaft 64 passes through the pressing assembly 61, the second torsion spring 63, and the cam assembly 62, allowing the cam assembly 62 to rotate relative to the pressing assembly 61 to switch between a first state and a second state. The cam assembly 62 is provided with a protrusion 620. In the first state, the protrusion of the cam assembly 62 extends into the slot 122 through the through hole 112 and engages with the base 12. In the second state, the protrusion of the cam assembly 62 is housed in the second cavity 111. One end of the second torsion spring 63 is connected to the pressing assembly 61, and the other end is connected to the cam assembly 62. When the cam assembly 62 is in the first state, the second torsion spring 63 is in its natural state.

[0065] Specifically, Figure 4 shows an exploded view of the server board lifting device provided in this application embodiment, and Figure 5 shows an exploded view of the lock cylinder system structure in this application embodiment. The lock cylinder structure 6 is the core for realizing the height adjustment and locking function of the lifting device, including a pressing component 61, a cam component 62, a second torsion spring 63, and a second rotating shaft 64. The bracket assembly 1 adopts a split structure, including a bracket body 11 and a base 12. The bracket body 11 is the middle bracket of the handle, and the base 12 is located at the bottom of the entire device and has a supporting function. The base 12 has a first cavity 121, and the bracket body 11 is slidably connected to the first cavity 121 of the base 12. The bracket body 11 and the base 12 adopt a clearance fit to ensure that the bracket body 11 can slide up and down in the base 12 without displacement. The operator can adjust the height of the device by pushing the bracket body 11. The top of the bracket body 11 has a through hole through which the first rotating shaft 3 passes. The bracket body 11 is also provided with a protruding shaft 125 to fix the end of the locking fastener 5. The support body 11 has a second cavity 111, and the side wall of the support body 11 has a through hole 112 communicating with the second cavity 111. A pressing assembly 61 extends from the upper end of the support body 11 into the second cavity 111 and is slidably connected to the support body 11. A cam assembly 62 and a second torsion spring 63 are located within the pressing assembly 61, specifically between the left and right sides of the pressing assembly 61. The cam assembly 62 has at least one protrusion 620. There are two second torsion springs 63, one located between the cam assembly 62 and the left side of the pressing assembly 61, and the other located between the cam assembly 62 and the right side of the pressing assembly 61. The pressing assembly 61 can be designed as an integral structure or a split structure, wherein the split structure is easier to disassemble and assemble. The second rotating shaft 64 passes sequentially through the left side of the pressing assembly 61, one of the second torsion springs 63, the cam assembly 62, the other second torsion spring 63, and the right side of the pressing assembly 61, allowing the cam assembly 62 to rotate relative to the pressing assembly 61 around the second rotating shaft 64, switching between a first state and a second state. In the first state, the protrusion 620 of the cam assembly 62 extends through the through hole 112 into the slot 122 and engages with the base 12, fixing the support body 11 in place. At this time, the support body 11 is limited and fixed by the base 12, preventing sliding. In the second state, the protrusion 620 of the cam assembly 62 is housed within the second cavity 111, releasing the limiting effect between the support body 11 and the base 12, allowing relative sliding between them. The second torsion spring 63 passes through the second rotating shaft 64, with one end connected to the pressing assembly 61 and the other end connected to the cam assembly 62. When the cam assembly 62 is in the first state, the second torsion spring 63 is in its natural state.

[0066] In some embodiments, as shown in Figures 7 and 8, the cam assembly 62 is in the first state, with the protrusion 620 of the cam assembly 62 extending into the slot 122 through the through hole 112 and engaging with the base 12. When the operator needs to adjust the height of the device, in other words, when the support body 11 needs to be pulled out of the base 12, the operator presses down on the pressing assembly 61. The entire lock cylinder structure slides relative to the support body 11 in the vertical direction. At this time, the cam assembly 62 rotates counterclockwise around the second pivot 64 under the action of the inner wall of the through hole 112, as shown in Figure 9. When the operator continues to press down on the pressing assembly 61 until the protrusion 620 of the cam assembly 62 is completely retracted into the second cavity 111, the second torsion spring 63 is driven by the rotation of both ends and has a certain elastic potential energy. The limiting effect between the support body 11 and the base 12 is released, and relative sliding can occur between the support body 11 and the base 12, as shown in Figure 3. The operator can pull the support body 11 and slide it downwards or upwards relative to the base 12. When the lifting process ends, the operator releases the pressing component 61. Under the action of the torsional elastic potential energy of the second torsion spring 63, the cam component 62 rotates clockwise around the second rotating shaft 64 until it contacts the limiting part 615 on the pressing component 61. At the same time, the protrusion 620 of the cam component 62 extends through the through hole 112 into the slot 122 and engages with the base 12, returning to the first state. At this time, the operator can lift and remove the server board using the gripping plate 2. After the assembly process is completed, the operator presses the pressing component 61 downwards until the protrusion 620 of the cam component 62 is fully retracted into the second cavity 111, pushing the bracket body 11 downwards and returning it to the initial bottom position.

[0067] The server board lifting device provided in this embodiment allows for relative sliding between the support body 11 and the base 12. Since a gripping plate 2 is connected to the top of the support body, the height of the gripping plate 2 can be adjusted by lifting and pushing the support body 11, providing greater height space for board component layout and offering more possibilities for system layout. The lock cylinder structure 6 includes a pressing component 61, a cam component 62, a second torsion spring 63, and a second rotating shaft 64. When the height of the support body 11 needs to be adjusted, pressing the pressing component 61 downwards causes the protrusion 620 of the cam component 62 to be fully retracted into the second cavity 111, allowing the operator to slide the support body 11 upwards or downwards. When the operator releases the pressing component 61, the cam component 62 returns to its initial state due to the elastic potential energy of the second torsion spring 63, and the support body 11 is fixed by the base 12, preventing sliding. Therefore, the lock cylinder structure plays the role of locking the movement state of the bracket body 11. Only when the pressing component 61 is squeezed can the bracket body 11 slide relative to the base 12. When the pressing component 61 is released, the bracket body 11 is limited and fixed by the base 12 and cannot slide relative to the base.

[0068] In some embodiments of this application, referring to Figures 4 and 5, the pressing assembly 61 includes a pressing rod 611, a first connecting rod 612, a second connecting rod 613, and a connecting shaft 614; the pressing rod 611 is located between the first end of the first connecting rod 612 and the first end of the second connecting rod 613, the connecting shaft 614 is fixedly inserted between the first connecting rod 612, the pressing rod 611, and the second connecting rod 613, the cam assembly 62 and the second torsion spring 63 are located between the second end of the first connecting rod 612 and the second end of the second connecting rod 613, and the second rotating shaft 64 is inserted between the first connecting rod 612, the second torsion spring 63, the cam assembly 62, and the second connecting rod 613.

[0069] Specifically, as shown in Figures 4 and 5, the pressing assembly 61 includes a pressing rod 611, a first connecting rod 612, a second connecting rod 613, and a connecting shaft 614, meaning the pressing assembly 61 is a split structure. The pressing rod 611 has a button at its top and is snapped between a slot at the upper end of the first connecting rod 612 and a slot at the upper end of the second connecting rod 613. The connecting shaft 614 passes sequentially between the first connecting rod 612, the pressing rod 611, and the second connecting rod 613, reinforcing the fixed connection between them. The cam assembly 62 and the second torsion spring 63 are located between the lower ends of the first connecting rod 612 and the second connecting rod 613. Since the cam assembly 62 is located in the middle of the second rotating shaft 64, two second torsion springs 63 are provided to ensure that both sides of the cam assembly 62 are subjected to the force of the torsion springs. The two second torsion springs 63 are located on both sides of the cam assembly 62. The second rotating shaft 64 passes through the first connecting rod 612, one of the second torsion springs 63, the cam assembly 62, the other second torsion spring 63, and the second connecting rod 613. During the assembly process, the lower structure is first installed, that is, the second rotating shaft 64 is passed through to connect the first connecting rod 612, the second torsion spring 63, the cam assembly 62, and the second connecting rod 613. Then the upper structure is installed, that is, the connecting shaft 614 is passed through to connect the first connecting rod 612, the pressing rod 611, and the second connecting rod 613, completing the overall assembly of the lock cylinder structure.

[0070] In another embodiment, the pressing component 61 is designed as an integral structure, that is, the pressing rod 611, the first connecting rod 612, the second connecting rod 613 and the connecting shaft 614 are connected as a whole, that is, it is designed as a cylindrical structure with a closed upper end and a button, and an opening at the lower end for connecting the second rotating shaft 64, the second torsion spring 63 and the cam assembly 62. The lock cylinder structure needs to be assembled before it is installed into the bracket body 11. The assembly process of this structure is more complicated, but it involves fewer parts.

[0071] In some embodiments of this application, referring to FIG5, the end of the pressing rod 611 is provided with a pressing protrusion 6111; the pressing protrusion 6111 protrudes from the second cavity 111, making it convenient for the operator to contact and press, and squeeze the pressing rod 611 downward.

[0072] In some embodiments of this application, referring to FIG5, the cam assembly 62 includes a first cam 621 and a second cam 622; at least one of the first cam 621 and the second cam 622 has a protrusion 620, the first cam 621 is engaged in the second cam 622, and the first cam 621 passes through the second rotating shaft 64.

[0073] Specifically, as shown in Figure 5, the cam assembly 62 includes a first cam 621 and a second cam 622. The first cam 621 is the driving cam, and the second cam 622 is the driven cam. The first cam 621 passes through the second rotating shaft 64 and engages with the cam groove of the second cam 622, forming a single unit. Under the action of the inner wall of the through hole 112, the first cam 621 rotates counterclockwise around the second rotating shaft 64, causing the second cam 622 to rotate counterclockwise around the second rotating shaft 64. Both the first cam 621 and the second cam 622 have protrusions 620. The protrusion 620 of the first cam 621 extends through the through hole 112 into the slot 122 and engages with the base 12. The protrusion 620 of the second cam 622 contacts the limiting part 615 on the pressing assembly 61 and is limited and fixed.

[0074] In some embodiments of this application, referring to Figures 5 and 7, a limiting part 615 is provided near the second end of the first connecting rod 612 and the second connecting rod 613, which is suitable for placing the cam assembly 62 in a first state when it contacts the cam assembly 62.

[0075] Specifically, as shown in Figures 5 and 7, the first connecting rod 612 and the second connecting rod 613 are provided with limiting portions 615 near their lower ends, which are used to contact the protrusion 620 of the second cam 622 and limit and fix the cam assembly 62. When the operator releases the pressing rod 611, the first cam 621 rotates clockwise around the second rotating shaft 64 under the action of the elastic potential energy of the second torsion spring 63 until the protrusion 620 of the second cam 622 contacts the limiting portion 615 of the first connecting rod 612 and the second connecting rod 613, and returns to the first state. At this time, the protrusion 620 of the first cam 621 extends into the slot 122 through the through hole 112 and is engaged and fixed with the base 12.

[0076] In some embodiments of this application, referring to Figures 1 to 3, a limiting rod 7 is also included; the side wall of the base 12 has a limiting opening 123 communicating with the first cavity 121, and the limiting rod 7 is fixed to the end of the support body 11. When the support body 11 slides relative to the base 12, the limiting rod 7 moves between the two ends of the limiting opening 123.

[0077] Specifically, as shown in Figures 1 to 3, a limiting rod 7, i.e., a limiting screw, is fixed to the lower end of the bracket body 11. The side wall of the base 12 has a limiting opening 123 communicating with the first cavity 121, and the limiting opening 123 is in the shape of a flat racetrack. When the bracket body 11 slides relative to the base 12, the limiting rod 7 moves between the upper and lower ends of the limiting opening 123, that is, the lower end of the bracket body 11 cannot be lower than the lower end of the limiting opening 123, and the upper end of the bracket body 11 cannot be higher than the upper end of the limiting opening 123. Therefore, with the help of the limiting rod 7 and the limiting opening 123 structure, the bracket body 11 is prevented from falling off or impacting the surface of the circuit board during sliding, thus preventing damage to the circuit board.

[0078] In some embodiments of this application, referring to Figures 1 to 3, one end of the limiting opening 123 is spaced apart from the top of the base 12, and the other end of the limiting opening 123 is spaced apart from the bottom of the base 12. Both ends of the limiting opening 123 are arc-shaped.

[0079] Specifically, as shown in Figures 1 to 3, the upper end of the limiting opening 123 is spaced apart from the upper end of the base 12, and the lower end of the limiting opening 123 is spaced apart from the lower end of the base 12, to prevent the bracket body 11 from sliding off the upper end of the base 12 or sliding to the bottom of the base 12 and colliding. Both ends of the limiting opening 123 are arc-shaped, and the middle is strip-shaped, that is, the limiting opening 123 is racetrack-shaped. The arc-shaped structure at both ends helps to buffer collisions and avoid damage to the limiting rod 7 and the bracket body 11.

[0080] In some embodiments of this application, referring to Figures 4 to 6, a compression spring 8 is also included; the first end of the first connecting rod 612 and / or the first end of the second connecting rod 613 have a first snap-fit ​​protrusion 6121, and the end near the bracket body 11 is provided with a second snap-fit ​​protrusion 113, and the compression spring 8 is fixed between the first snap-fit ​​protrusion 6121 and the second snap-fit ​​protrusion 113.

[0081] Specifically, as shown in Figures 4 to 6, the upper ends of the first connecting rod 612 and the second connecting rod 613 have an outwardly protruding structure, namely a first locking protrusion 6121, and the upper end near the bracket body 11 also has an outwardly protruding structure, namely a second locking protrusion 113. The compression spring 8 is fixed to the first locking protrusion 6121 and the second locking protrusion 113.

[0082] Between. The compression spring 8 has a rebound function. When the operator presses down on the pressing rod 611, the compression spring 8 is compressed and has elastic potential energy. When the operator releases the pressing rod 611, the elastic potential energy of the compression spring 8 is released, and the pressing rod 611 rebounds to the top, completing the rebound reset of the pressing assembly 61, which is convenient for the next operation.

[0083] In some embodiments of this application, referring to Figures 1, 4 and 5, a cover plate 91 and a fastener 92 are also included; the cover plate 91 is fixed to the end of the bracket body 11, the first snap-fit ​​protrusion 6121 faces the cover plate 91 from the side away from the compression spring 8, and the fastener 92 passes between the cover plate 91 and the end of the bracket body 11.

[0084] Specifically, as shown in Figures 1, 4, and 5, a compression spring 8 is fixed to the lower part of the first snap-fit ​​protrusion 6121, and the upper part faces the cover plate 91. Fasteners 92, i.e., cover plate screws, fix the cover plate 91 to the top of the bracket body 11. When the operator releases the pressing rod 611, the compression spring 8 pushes the pressing rod 611 back to the top, and the cover plate 91 limits the highest movement position of the pressing rod 611, preventing it from being dislodged.

[0085] In some embodiments of this application, referring to Figures 1 to 3, there are two gripping plates 2, first rotating shafts 3, first torsion springs 4 and locking fasteners 5; one gripping plate 2, one first rotating shaft 3 and one first torsion spring 4 are located on one side of the bracket assembly 1, and the other gripping plate 2, another first rotating shaft 3 and another first torsion spring 4 are located on the other side of the bracket assembly 1, and the two locking fasteners 5 are arranged opposite each other.

[0086] Specifically, as shown in Figures 1 to 3, to ensure balanced lifting force on both sides, a gripping plate 2 is provided on each side of the support body 11, namely a left gripping plate 2 and a right gripping plate 2. Each gripping plate 2 is provided with a first rotating shaft 3, a first torsion spring 4, and a locking element 5. The locking element 5 connecting the left gripping plate 2 is located on the front side of the support body 11, and the locking element 5 connecting the right gripping plate 2 is located on the rear side of the support body 11.

[0087] In some embodiments of this application, referring to Figures 1 to 3, the end of the base 12 is provided with a screw hole 124, which is suitable for fixed connection with the server board by means of a through bolt.

[0088] Specifically, as shown in Figures 1 to 3, a screw hole is provided on each of the two sides of the bottom of the base 12.

[0089] 124. A bolt is inserted through screw hole 124 to fix it to the server board, completing the overall lifting and moving of the board.

[0091] Specifically, as shown in Figure 1, a fixing plate 126 is provided at the bottom of the base 12, and the cross-sectional area of ​​the fixing plate 126 is larger than that of the base 12. Screw holes 124 are provided on both sides of the fixing plate 126 to facilitate the installation of bolts without affecting the structural stability of the base 12.

[0092] This application also provides a computer device, including a server chassis and a server board lifting device according to any of the above embodiments, wherein the server board lifting device is disposed inside the server chassis. In the non-use state, the holding plate is folded and close to the bracket assembly, avoiding occupying internal space of the server chassis and providing more space for device placement. In the use state, by actuating the other end of the locking fastener, the holding plate is opened, facilitating the operator to lift the server board.
