Description

Technical Field

[0001] This invention relates to the field of GPU server technology, specifically to a quick assembly / disassembly tooling for GPU servers and a GPU server. Background Technology

[0002] A GPU (Graphics Processing Unit) server is a computing device equipped with a high-performance GPU, widely used in fields such as artificial intelligence training, deep learning, scientific computing, and graphics rendering. Compared to traditional CPU servers, GPU servers significantly improve the efficiency of large-scale data processing and complex computational tasks due to their powerful parallel computing capabilities. In a GPU server, the GPU itself is typically plugged into the server's circuit board via a PCIe slot and secured with locking clips to prevent it from loosening or falling off due to server vibration or impacts during transportation.

[0003] Extensive research revealed problems with the assembly and disassembly of GPUs in existing GPU server architectures. Due to the compact internal space of servers, when multiple GPUs are installed side-by-side, the narrow gaps between adjacent GPUs make it difficult for operators to reach in and directly grasp the GPUs for insertion and removal. Furthermore, the weight of the GPUs makes it difficult to maintain stability during manual insertion and removal, easily causing the GPUs to tilt and damage the PCIe slot or the GPU's contacts. Additionally, the GPUs are secured by locking clips on the PCIe slots, requiring manual downward pressing to unlock them before disassembly. Given the limited internal space of servers, operators cannot simultaneously press the locking clips and insert / remove the GPUs, often requiring two people or tools, resulting in cumbersome and inefficient operations. Therefore, based on the above research and existing technologies, this paper proposes a rapid assembly and disassembly fixture and GPU server for GPU servers to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a quick assembly / disassembly tooling for GPU servers and a GPU server in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A quick assembly / disassembly fixture for GPU servers, characterized in that it comprises:

[0007] Install longitudinal plates;

[0008] The first clamping mechanism and the second clamping mechanism are spaced apart on the bottom surface of the mounting plate along its length direction, and are used to clamp the bottom of the GPU body from below after it is inserted into the gap between multiple GPU bodies.

[0009] Both the first clamping mechanism and the second clamping mechanism include:

[0010] A horizontal support plate is slidably connected to the bottom surface of the mounting vertical plate. A first clamping mechanism is slidably connected to the mounting vertical plate via a connecting bracket one, and a second clamping mechanism is slidably connected to the mounting vertical plate via a connecting bracket two.

[0011] The support arm assembly is located on the bottom surface of the support plate and has two oppositely arranged and openable lower support arms. The two lower support arms are initially in a retracted position that is relatively far apart to form an insertion profile smaller than the width of the GPU body, which facilitates entry into the gap between multiple GPU bodies. After the two lower support arms are combined, they form a U-shaped structure for lifting and clamping the GPU body from below.

[0012] A linkage mechanism is provided on the support plate and is connected to the two lower arms for driving the two lower arms to switch between the retracted position and the clamping position.

[0013] Furthermore, the sliding direction of the support cross plate of the second clamping mechanism on the mounting longitudinal plate is configured to have a horizontal displacement while moving downward, so that when moving downward in the state of clamping the GPU body, the locking latch on the GPU server can be unlocked.

[0014] Furthermore, the linkage mechanism includes a support cylinder, which is fixedly installed on the support plate. A movable support plate is rotatably connected to the left side of the support cylinder. The rotation axis of the movable support plate is set in the vertical direction. A movable rod is rotatably connected to the upper end of the movable support plate. A connecting plate is rotatably connected to the rear end of the movable rod. The connecting plate is fixedly connected to the lower support arm located on the rear side. A movable rod is rotatably connected to the lower end of the movable support plate. A connecting plate is rotatably connected to the front end of the movable rod. The connecting plate is fixedly connected to the lower support arm located on the front side.

[0015] A connecting roller is fixedly installed on the right side of the movable support plate. The connecting roller passes through the support cylinder and is fixedly installed with a movable handle. A spring is wound around the outer circular wall of the connecting roller. One end of the spring is fixedly connected to the inner wall of the support cylinder, and the other end of the spring is fixedly connected to the connecting roller.

[0016] Furthermore, a limiting post is fixedly installed on the right side of the supporting cross plate, and in the initial state, the movable handle abuts against the limiting post;

[0017] The movable handle has a movable locking hole, and a support mounting chamber is fixedly installed on the support horizontal plate. A positioning block is slidably connected inside the support mounting chamber. A support rod is fixedly installed on the left side of the positioning block. The support rod passes through the support mounting chamber and extends to the outside of the support mounting chamber. A spring three is sleeved on the outer circular wall of the support rod. One end of the spring three is fixedly connected to the left side of the positioning block, and the other end of the spring three is fixedly connected to the inner side wall of the support mounting chamber.

[0018] A mounting block is fixedly installed on the left side of the support plate, and a rope is universally connected to the left end of the support rod. The upper end of the rope passes through the mounting block and is fixedly installed with a limiting block.

[0019] Furthermore, a connecting block is fixedly installed on the bottom surface of the mounting plate. Connecting grooves are provided on both the front and rear sides of the connecting block. Movable locking blocks are slidably connected inside the connecting grooves. Two springs are fixedly installed inside the connecting grooves. One end of each spring is fixedly connected to the opposite side of the two movable locking blocks.

[0020] The quick assembly / disassembly fixture also includes a positioning bracket, which is used for detachable connection to the top of the GPU body. The positioning bracket has snap-fit ​​holes on both the front and rear sides, and the movable latch is movably snapped into the snap-fit ​​holes. The bottom surface of the movable latch facing the positioning bracket is set as an upwardly inclined slope.

[0021] Furthermore, a second screw is connected through the inner bottom surface of the positioning bracket, and the second screw is used to connect with the threaded groove on the top surface of the GPU body.

[0022] Furthermore, the mounting plate is provided with an adjustment mechanism for adjusting the position of the first clamping mechanism. The adjustment mechanism includes a support hole, which is opened on the side of the mounting plate. A lead screw is rotatably connected to the inside of the support hole via a bearing. A load-bearing slider is threadedly connected to the outer circular wall of the lead screw. A limiting rod is fixedly installed inside the support hole. The load-bearing slider is slidably connected to the limiting rod. The left end of the lead screw passes through the mounting plate and is fixedly installed with a knob.

[0023] The inner two sides of the connecting bracket are fixedly connected to the front and rear sides of the bearing slider.

[0024] Furthermore, the mounting longitudinal plate is provided with an inclined driving mechanism for driving the second clamping mechanism to slide in an inclined direction. The inclined driving mechanism includes a connecting hole, which is opened on the side of the mounting longitudinal plate. The connecting hole is inclined downward from left to right. A sliding support rod is fixedly installed inside the connecting hole. A sliding base is slidably connected to the sliding support rod. A spring is sleeved on the outer circular wall of the sliding support rod. One end of the spring is fixedly connected to the right side of the sliding base, and the other end of the spring is fixedly connected to the inner side wall of the connecting hole. The inner two sides of the connecting bracket are respectively fixedly connected to the front and rear sides of the sliding base.

[0025] A GPU server includes a chassis body, a circuit board mounted on the bottom surface of the chassis body, a PCIe slot for inserting a GPU body on the circuit board, a locking buckle provided on the right side of the PCIe slot, a GPU body disposed inside the chassis body, and a quick-release fixture for disassembling and assembling the GPU body.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. By using the mounting vertical plate, connecting bracket one, connecting bracket two, supporting horizontal plate, lower support arm, rubber guard plate, connecting plate one, connecting plate two, movable support plate, movable rod one, movable rod two, limit slide rail and limit slider in coordination, the lower support arm can be closed during disassembly and assembly to lift and clamp the GPU body from below. In the initial state, the lower support arm is kept open to facilitate access to the gaps between multiple GPU bodies. This solves the problem of compact internal space and inconvenient operation in servers, and achieves the effect of quick clamping and safe operation.

[0028] By using the connection hole, sliding support rod, sliding base, spring one and connection bracket two in cooperation, the second clamping mechanism can slide in the inclined direction when the vertical plate is moved downward, so that the lower support arm generates horizontal displacement while moving downward, thereby automatically triggering the locking buckle to unlock. This solves the problem of needing to press the locking buckle separately and the limited operating space in traditional disassembly and assembly, and achieves the integration of unlocking and insertion.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] In one typical implementation of this application, please refer to Figures 1-10 A quick assembly and disassembly fixture for GPU servers includes a mounting plate 3, which serves as the support base for the entire fixture. A handheld frame 4 is fixedly mounted on the top surface of the mounting plate 3. The handheld frame 4 provides a gripping area for the operator to facilitate lifting and pressing operations.

[0043] When the operator holds the handheld frame 4 and pulls it upward, the entire fixture, along with the GPU body 2 it holds, can be removed from the chassis; when pressed downward, the fixture can be placed on top of the GPU body 2 or an unlocking operation can be performed.

[0044] The bottom surface of the mounting plate 3 is provided with a first clamping mechanism and a second clamping mechanism along its length. The first clamping mechanism is located on the left side and the second clamping mechanism is located on the right side. The first clamping mechanism is slidably connected to the mounting plate 3 through a connecting bracket 1 5, and the second clamping mechanism is slidably connected to the mounting plate 3 through a connecting bracket 2 6. The function of the first clamping mechanism and the second clamping mechanism is to clamp the GPU body 2 from different positions from below to ensure that the GPU body 2 remains balanced during the disassembly and assembly process and does not tilt or shake.

[0045] When the operator places the fixture on top of the GPU body 2, the lower support arms 8 of the first clamping mechanism and the second clamping mechanism are located on the left and right sides of the bottom of the GPU body 2, respectively. The GPU body 2 can be clamped by driving the lower support arms 8 to close through the linkage mechanism.

[0046] Both the first and second clamping mechanisms include a supporting horizontal plate 7, a support arm assembly, and a linkage mechanism. The supporting horizontal plate 7 supports the support arm assembly and the linkage mechanism, serving as their mounting base. When the connecting bracket 1 5 or the connecting bracket 2 6 moves, the supporting horizontal plate 7 moves accordingly, causing the entire clamping mechanism to move.

[0047] The support arm assembly is located on the bottom surface of the supporting horizontal plate 7 and has two oppositely arranged and openable lower support arms 8. The two lower support arms 8 are symmetrically arranged. The function of the support arm assembly is to lift and clamp the GPU body 2 from below. Rubber guard plates 9 are fixedly installed on the inner side of the two lower support arms 8. The rubber guard plates 9 are made of flexible rubber material and have anti-slip texture on the surface. The function of the rubber guard plates 9 is to provide cushioning and protection when clamping the GPU body 2, to prevent scratching the surface of the GPU body 2, and to increase friction to prevent the GPU body 2 from slipping. In the initial state, the two lower support arms 8 are in a relatively far retracted position. At this time, the distance between the two lower support arms 8 is greater than the width of the GPU body 2, and the resulting insertion profile is smaller than the width of the GPU body 2. This makes it easy to smoothly enter the narrow gap between multiple GPU bodies 2 when lowered vertically from above without colliding with adjacent GPU bodies 2.

[0048] When it is necessary to clamp the GPU body 2, the two lower support arms 8 move towards each other and merge to form a U-shaped structure for lifting and clamping the GPU body 2 from below. At this time, the two rubber guards 9 are tightly attached to the front and rear sides of the GPU body 2, clamping the GPU body 2 from both sides. At the same time, the bottom of the lower support arm 8 supports the bottom surface of the GPU body 2, realizing three-point positioning clamping of the GPU body 2.

[0049] The linkage mechanism is set on the support plate 7 and is connected to the two lower support arms 8. The function of the linkage mechanism is to drive the two lower support arms 8 to switch between the retracted position and the clamping position. The specific structure of the linkage mechanism includes a support cylinder 32, which is fixedly installed on the side of the support plate 7. The function of the support cylinder 32 is to serve as the mounting base of the movable support plate 53 and to accommodate the spring 40.

[0050] A movable support plate 53 is rotatably connected to the left side of the support cylinder 32. The upper end of the movable support plate 53 is rotatably connected to a movable rod 12 via a pivot. The rear end of the movable rod is rotatably connected to a connecting plate 13 via a pivot. The connecting plate 13 is a vertically arranged elongated plate structure. Its bottom is fixedly connected to the top of the lower support arm 8 located on the rear side. The connecting plate 13 moves synchronously with the lower support arm 8. The lower end of the movable support plate 53 is rotatably connected to a movable rod 2 14 via a pivot. The front end of the movable rod 2 14 is rotatably connected to a connecting plate 2 52 via a pivot. The connecting plate 2 52 is a vertically arranged elongated plate structure. Its bottom is fixedly connected to the top of the lower support arm 8 located on the front side. The connecting plate 2 52 moves synchronously with the lower support arm 8. The function of the movable rod 12 and the movable rod 2 14 is to convert the rotation of the movable support plate 53 into the linear sliding of the connecting plate 13 and the connecting plate 2 52.

[0051] A limiting slide rail 18 with an I-shaped cross section is fixedly installed on the left side of the supporting horizontal plate 7. The function of the limiting slide rail 18 is to guide the connecting plate 13 and the connecting plate 52 to slide in a straight line to ensure motion accuracy. Limiting sliders 15 are fixedly installed on the right side of the connecting plate 13 and the connecting plate 52. The limiting sliders 15 are slider structures that slide in conjunction with the limiting slide rail 18. The inner side of the slider has a groove that matches the contour of the limiting slide rail 18. The limiting sliders 15 are slidably connected to the limiting slide rail 18, thereby restricting the degree of freedom of movement of the connecting plate 13 and the connecting plate 52, so that they can only slide in a straight line along the limiting slide rail 18 in the front-back direction, and cannot move left or right or rotate.

[0052] A connecting roller 39 is fixedly installed on the right side of the movable support plate 53. Its left end is fixedly connected to the right side of the movable support plate 53, and its right end passes through the support cylinder 32 and extends to the outside of the right side of the support cylinder 32. The function of the connecting roller 39 is to transmit torque and transmit the rotation of the movable handle 41 to the movable support plate 53. The right end of the connecting roller 39 is fixedly installed with the movable handle 41. The function of the movable handle 41 is to allow the operator to manually operate and drive the entire linkage mechanism to move.

[0053] A spring 40 is wound around the outer circular wall of the connecting roller 39. The spring 40 is a planar spiral spring, with its inner end fixedly connected to the outer circular wall of the connecting roller 39 and its outer end fixedly connected to the inner circular wall of the support cylinder 32. The function of the spring 40 is to store elastic potential energy when the movable handle 41 rotates, and to drive the movable handle 41 to automatically reset after the lock is released. When the movable handle 41 rotates clockwise, it drives the connecting roller 39 to rotate, causing the spring 40 to gradually tighten. When the movable handle 41 rotates counterclockwise, the spring 40 releases its elastic force, driving the movable handle 41 to reset.

[0054] Specifically, when the operator rotates the movable handle 41 clockwise, the movable handle 41 drives the connecting roller 39 to rotate clockwise, the connecting roller 39 drives the movable support plate 53 to rotate clockwise around the vertical axis, the rotation of the movable support plate 53 drives the movable rod 12 connected to its upper end to move forward, and drives the movable rod 2 14 connected to its lower end to move backward. The movement of the movable rod 12 forward pushes the connecting plate 13 to slide forward along the limiting slide rail 18, and the movement of the movable rod 2 14 backward pushes the connecting plate 2 52 to slide backward along the limiting slide rail 18. The connecting plate 13 and the connecting plate 2 52 respectively drive the two lower support arms 8 fixedly connected to them to move towards each other: the front lower support arm 8 moves backward and the rear lower support arm 8 moves forward. When the movable handle 41 is rotated to the limit position, the two lower support arms 8 are completely closed and clamp the GPU body 2 from the front and rear sides.

[0055] When the operator rotates the movable handle 41 counterclockwise, the components move in the opposite direction, and the two lower support arms 8 move back to open, releasing the GPU body 2. By adopting a double-link symmetrical transmission method, the structure is compact and the transmission is smooth, which can ensure that the two lower support arms 8 move synchronously towards or away from each other, so as to achieve uniform clamping of the GPU body 2 and avoid the GPU body 2 tilting or slipping due to uneven clamping force.

[0056] The linkage mechanism is also equipped with a locking component. The function of the locking component is to automatically lock the position of the movable handle 41 when it rotates to the clamping position, so as to prevent the lower support arm 8 from loosening due to vibration or accidental contact during the insertion and removal process. The locking component is located on the support plate 7 and is arranged around the movable handle 41.

[0057] Specifically, a limiting post 43 is fixedly installed on the right side of the supporting horizontal plate 7. In the initial state, the right side of the movable handle 41 abuts against the limiting post 43. The function of the limiting post 43 is to limit the initial position of the movable handle 41 and ensure that the position is consistent after each reset.

[0058] The movable handle 41 has a movable locking hole 42, which cooperates with the positioning block 44 to achieve a locking function. The support mounting chamber 16 is fixedly installed on the support plate 7. The support mounting chamber 16 is a rectangular hollow box. The function of the support mounting chamber 16 is to accommodate the positioning block 44, the support rod 45 and the spring 46, providing them with installation space and sliding guidance.

[0059] The support mounting chamber 16 has a sliding connection to a positioning block 44. The positioning block 44 is a rectangular block structure that can slide within the support mounting chamber 16. The side of the positioning block 44 facing the movable handle 41 is set as an inclined surface. The function of the positioning block 44 is to insert into the movable locking hole 42 after the movable handle 41 is rotated into place, thereby locking the position of the movable handle 41. The inclined surface design makes it easy for the right side of the movable handle 41 to smoothly press the positioning block 44 to move to the left when the movable handle 41 is rotated, without causing jamming.

[0060] A support rod 45 is fixedly installed on the left side of the positioning block 44 and is set horizontally in the left and right direction. Its right end is fixedly connected to the left side of the positioning block 44, and its left end passes through the left side wall of the support mounting chamber 16 and extends to the outside of the support mounting chamber 16. The support rod 45 is slidably connected to the left side wall of the support mounting chamber 16 and can move freely left and right.

[0061] A spring 46 is fitted on the outer circular wall of the support rod 45. One end of the spring 46 is fixedly connected to the left side of the positioning block 44, and the other end of the spring 46 is fixedly connected to the inner side wall of the support mounting chamber 16. It is always in a compressed state. The function of the spring 46 is to apply a rightward pushing force to the positioning block 44, so that the positioning block 44 has a tendency to extend to the right.

[0062] A mounting block 17 is fixedly installed on the left side of the supporting horizontal plate 7. The mounting block 17 has a circular through hole in its center for the rope 47 to pass through. The function of the mounting block 17 is to guide the direction of the rope 47 and prevent it from interfering with other components. The left end of the support rod 45 is connected to the rope 47 via a universal joint. The universal joint allows the rope 47 to rotate freely within a certain angle range, preventing the rope 47 from getting stuck due to angle changes. The upper end of the rope 47 passes through the through hole of the mounting block 17 and is fixedly installed with a limiting block 48. The limiting block 48 has a diameter larger than the through hole diameter on the mounting block 17. The function of the rope 47 and the limiting block 48 is to allow the operator to remotely control the retraction of the positioning block 44, thus achieving the unlocking operation.

[0063] Specifically, when the operator rotates the movable handle 41 clockwise, the movable handle 41 gradually approaches and presses against the inclined surface of the positioning block 44. Due to the guiding effect of the inclined surface, the positioning block 44 is subjected to pressure, overcoming the elastic force of the spring 46 and moving to the left, making room for the continued rotation of the movable handle 41. When the movable handle 41 rotates until the movable locking hole 42 is completely aligned with the positioning block 44, the positioning block 44 loses the obstruction of the right side of the movable handle 41, and the spring 46 releases its elastic force instantly, driving the positioning block 44 to quickly extend to the right and insert into the movable locking hole 42, indicating that the locking is complete. At this time, the positioning block 44 is locked in the movable locking hole 42, restricting the rotational freedom of the movable handle 41, making it impossible for the movable handle 41 to rotate back, thereby locking the two lower support arms 8 in the closed clamping state.

[0064] When the GPU body 2 needs to be released, the operator pulls the limit block 48 upward. The limit block 48 drives the rope 47 to move upward. The rope 47 pulls the support rod 45 to the left through the universal joint. The support rod 45 drives the positioning block 44 to move to the left against the elastic force of the spring 46, so that the positioning block 44 exits the movable locking hole 42. At this time, the lock is released, the spring 40 releases the stored elastic potential energy, drives the movable handle 41 to rotate counterclockwise to automatically reset until it abuts against the limit post 43.

[0065] The quick-release fixture also includes a positioning component, which is used to quickly and accurately position and connect the fixture to the GPU body 2 to be disassembled, ensuring accurate clamping position. The positioning component is located between the bottom surface of the mounting plate 3 and the top surface of the GPU body 2.

[0066] Specifically, a connecting block 10 is fixedly installed on the bottom surface of the mounting plate 3. The connecting block 10 is a rectangular block structure located at the center of the bottom surface of the mounting plate 3, between the first clamping mechanism and the second clamping mechanism. Connecting grooves 36 are provided on both the front and rear sides of the connecting block 10. The function of the connecting grooves 36 is to accommodate the movable locking blocks 37 and provide sliding guidance for them. The movable locking blocks 37 are slidably connected inside the connecting grooves 36. Two springs 38 are fixedly installed inside the connecting grooves 36, and one end of each spring 38 is connected to one of the two movable locking blocks 37. The opposing sides are fixedly connected, that is, the rear side of the front movable block 37 is connected to the front end of a second spring 38, and the front side of the rear movable block 37 is connected to the rear end of another second spring 38. The other ends of the two second springs 38 are fixedly connected to the front and rear inner walls of the connecting groove 36 respectively. The second spring 38 is always in a compressed state, applying an outward pushing force to the movable block 37, so that the two movable blocks 37 have a tendency to extend in opposite directions. The function of the second spring 38 is to drive the movable block 37 to extend outward and reset it after the external force disappears.

[0067] The quick-assembly / disassembly fixture also includes a positioning bracket 11, which has a U-shaped structure and its dimensions are adapted to the top contour of the GPU body 2. The positioning bracket 11 is detachably connected to the GPU body 2 and serves as a positioning interface between the fixture and the GPU body 2. The positioning bracket 11 has snap-fit ​​holes 35 on both its front and rear sides. The snap-fit ​​holes 35 are rectangular through holes, and their positions correspond to the shape and position of the front end of the movable latch 37, for movably snapping into place. The bottom surface of the movable latch 37 facing the positioning bracket 11 is set as an upwardly inclined slope, the angle of which matches the chamfer angle of the top edge of the positioning bracket 11, so that it can be smoothly squeezed and compressed back when pressed downwards.

[0068] The inner bottom surface of the positioning bracket 11 is connected by a screw 2 50. The screw 2 50 is a hand screw with a large head and knurling, which is easy to tighten or loosen manually. The screw 2 50 is used to connect with the threaded groove 2 49 on the top surface of the GPU body 2. The function of the screw 2 50 is to fix the positioning bracket 11 and the GPU body 2 into one piece.

[0069] Specifically, when the operator needs to connect the fixture to the GPU body 2, which is already fixed with the positioning bracket 11, the fixture is first placed directly above the GPU body 2, aligning the connecting block 10 with the positioning bracket 11. Then, the mounting plate 3 is moved downwards, causing the connecting block 10 to move vertically downwards. As the connecting block 10 moves downwards, the inclined surface of the lower edge of the front end of the movable locking block 37 first contacts the top edge of the positioning bracket 11. Due to the guiding effect of the inclined surface, the top edge of the positioning bracket 11 presses against the inclined surface of the movable locking block 37, generating an inward force. The force of the component causes the movable locking block 37 to retract into the connecting groove 36 against the elastic force of the second spring 38. When the connecting block 10 continues to move down until the front end of the movable locking block 37 is aligned with the snap-fit ​​hole 35 on the positioning bracket 11, the movable locking block 37 loses the obstruction of the top surface of the positioning bracket 11. The second spring 38 releases its elastic force instantly, driving the movable locking block 37 to extend outward quickly, and its front end is inserted into the snap-fit ​​hole 35. At this time, the movable locking block 37 is locked in the snap-fit ​​hole 35, fixing the mounting vertical plate 3 and the positioning bracket 11, realizing the precise positioning of the tooling and the GPU body 2.

[0070] The mounting plate 3 is equipped with an adjustment mechanism for adjusting the position of the first clamping mechanism. The adjustment mechanism is used to precisely adjust the position of the first clamping mechanism according to the GPU body 2 of different lengths, so that the fixture can be compatible with GPU bodies 2 of various specifications. The adjustment mechanism is located on the left side of the mounting plate 3.

[0071] Specifically, a support hole 26 is provided on the side of the mounting plate 3. A lead screw 29 is rotatably connected to the inside of the support hole 26 through a bearing. A bearing slider 28 is threadedly connected to the outer circular wall of the lead screw 29. The bearing slider 28 is a rectangular block structure with a threaded through hole in its middle that mates with the lead screw 29. The function of the bearing slider 28 is to support the connecting bracket 5 and move under the drive of the lead screw 29, thereby driving the first clamping mechanism to move.

[0072] A limiting rod 51 is fixedly installed inside the support hole 26. A guide hole is provided on the upper part of the bearing slider 28 to slide with the limiting rod 51. The limiting rod 51 passes through this guide hole and is slidably connected to the bearing slider 28. The limiting rod 51 restricts the rotational freedom of the bearing slider 28, allowing it to move linearly along the axis of the lead screw 29 and preventing it from rotating with the lead screw 29. The left end of the lead screw 29 passes through the left side wall of the mounting longitudinal plate 3 and extends to the outside of the mounting longitudinal plate 3. A knob 27 is fixedly installed on the left end of the lead screw 29. The knob 27 is a circular handwheel with knurled edges on its outer circumference for easy gripping and rotation by the operator. The knob 27 is for manual operation to drive the adjustment mechanism.

[0073] The inner sides of the connecting bracket 5 are fixedly connected to the front and rear sides of the bearing slider 28. When the bearing slider 28 moves, it drives the connecting bracket 5 to move together, thereby driving the first clamping mechanism to move as a whole.

[0074] Specifically, when the position of the first clamping mechanism needs to be adjusted, the operator rotates knob 27, which drives the lead screw 29 to rotate. Due to the limiting effect of the limiting rod 51, the bearing slider 28 cannot rotate with the lead screw 29. Therefore, under the thread drive of the lead screw 29, the bearing slider 28 moves along the axial direction of the lead screw 29. When the bearing slider 28 moves, it drives the first clamping mechanism to move left and right as a whole through the connecting bracket 5, thereby changing the distance between the first clamping mechanism and the second clamping mechanism to match the GPU body 2 of different lengths.

[0075] The mounting plate 3 is provided with a tilting drive mechanism for driving the second clamping mechanism to slide in the tilting direction. The tilting drive mechanism causes the second clamping mechanism to generate a horizontal displacement while moving downward, thereby triggering the locking buckle 23 to unlock. The tilting drive mechanism is located on the right side of the mounting plate 3.

[0076] Specifically, the side of the mounting plate 3 is provided with a connecting hole 30. The connecting hole 30 is a long strip-shaped through hole that runs through the front and rear sides of the mounting plate 3. It is set inclined downward from left to right, that is, the left end is higher than the right end, forming a certain tilt angle. The function of the connecting hole 30 is to guide the sliding base 33 to slide along the tilt direction.

[0077] A sliding support rod 31 is fixedly installed inside the connecting hole 30. The function of the sliding support rod 31 is to support the sliding base 33 and provide sliding guidance for it. The sliding base 33 is slidably connected to the sliding support rod 31. A circular through hole with clearance fit with the sliding support rod 31 is opened in the middle. The sliding base 33 can slide freely along the sliding support rod 31. The function of the sliding base 33 is to support the connecting bracket 6 and slide in the inclined direction.

[0078] A spring 34 is fitted on the outer circular wall of the sliding support rod 31. Its inner diameter is larger than the outer diameter of the sliding support rod 31, and it can extend and retract freely. One end of the spring 34 is fixedly connected to the right side of the sliding base 33, and the other end of the spring 34 is fixedly connected to the inner side wall of the connecting hole 30. The function of the spring 34 is to be compressed when the sliding base 33 moves to the right to store energy; when the external force disappears, it drives the sliding base 33 to slide to the left to reset.

[0079] The inner sides of the connecting bracket 2 6 are fixedly connected to the front and rear sides of the sliding base 33, respectively. That is, the top of the connecting bracket 2 6 and the bottom surface of the sliding base 33 are fixedly connected by bolts. With this connection method, when the sliding base 33 moves, it drives the connecting bracket 2 6 to move together, thereby driving the second clamping mechanism to move as a whole.

[0080] Specifically, when the second clamping mechanism is clamping the GPU body 2, if the operator moves the mounting plate 3 downward, the second clamping mechanism will move along the inclined connecting hole 30, that is, slide to the right and downward along the sliding support rod 31. The lower support arm 8 at its bottom will generate a horizontal displacement to the right while moving downward, so that it can contact and push the locking buckle 23 downward from the left side, so that the locking buckle 23 can rotate downward to unlock. The spring 34 is compressed when the sliding base 33 moves to the right. After unlocking, if the operator lifts the mounting plate 3 upward, the spring 34 releases its elastic force and drives the sliding base 33 to slide to the left to reset, preparing for the next operation.

[0081] As a preferred embodiment of this example, please refer to [link / reference]. Figures 1 to 11 A GPU server includes a chassis body 1, a circuit board 21, several PCIe slots 22, locking clips 23, a GPU body 2, and a quick-assembly / disassembly fixture as described in Example 1.

[0082] The main body of the chassis 1 is the external metal shell of the server, made of high-strength steel plate, which has good structural strength and electromagnetic shielding performance. The function of the main body of the chassis 1 is to house and protect the internal components and provide a mounting base for each component.

[0083] A circuit board 21 is fixed to the bottom of the main chassis 1 with multiple bolts. The circuit board 21 is the motherboard of the server, which integrates various electronic components such as the CPU, memory slots, and expansion slots. The function of the circuit board 21 is to connect the various electronic components and realize data transmission and power supply.

[0084] The circuit board 21 is equipped with a PCIe slot 22 for inserting the GPU body 2. The PCIe slot 22 is an expansion slot that conforms to the PCI Express standard. It is arranged side by side with equal spacing in the left and right direction. The slot has multiple elastic contacts inside, which are used to form an electrical connection with the gold fingers of the GPU body 2. The function of the PCIe slot 22 is to install the GPU body 2 and provide data transmission and power supply interfaces.

[0085] A locking clip 23 is located on the right side of the PCIe slot 22. The locking clip 23 is an injection-molded engineering plastic part with elasticity. Its bottom is rotatably connected to the housing or circuit board 21 of the PCIe slot 22 via a pin, allowing it to rotate up and down around the pin. A hook is located at the top of the locking clip 23. When the GPU body 2 is fully inserted into the PCIe slot 22, the hook automatically engages with the groove at the tail of the gold fingers of the GPU body 2. The function of the locking clip 23 is to lock the GPU body 2 in the slot, preventing it from loosening or falling out due to vibration or transportation.

[0086] A mounting frame 19 is fixedly installed on the left side of the interior of the chassis body 1. The mounting frame 19 is a rectangular frame structure, formed by stamping metal sheet, and is vertically installed on the left inner wall of the chassis body 1. Its height matches the height of the left end of the GPU body 2. The mounting frame 19 has several rectangular holes corresponding to the GPU body 2, and the size of the rectangular holes is slightly larger than the cross-sectional size of the left end of the GPU body 2. The function of the mounting frame 19 is to accommodate the left end of the GPU body 2 and provide auxiliary support for it, preventing the GPU body 2 from bending and deforming due to excessive cantilever length.

[0087] A connecting lug 24 is fixedly installed on the left side of the GPU body 2. The connecting lug 24 is a rectangular iron plate with a round hole on the top surface. The function of the connecting lug 24 is to provide an interface for connection with the mounting frame 19. A screw 25 is threaded through the connecting lug 24. The screw 25 is a hand screw with a large head and knurling for easy manual operation. A threaded groove 20 is provided on the top surface of the mounting frame 19. The threaded groove 20 is a threaded hole that mates with the screw 25. Its position corresponds to the round hole on the connecting lug 24.

[0088] After the GPU body 2 is inserted into the PCIe slot 22, the round hole on the connecting lug 24 aligns with the threaded groove 20 on the mounting frame 19. The lower end of the screw 25 passes through the round hole of the connecting lug 24 and is threaded into the inner wall of the threaded groove 20. The function of the screw 25 is to fix the left end of the GPU body 2 to the mounting frame 19, further enhancing the installation stability of the GPU body 2.

[0089] The following describes the complete working process of the GPU server and its rapid assembly / disassembly tooling in this embodiment:

[0090] Disassembly process: When it is necessary to disassemble and repair the damaged GPU body 2 inside the server, the operator first places the positioning bracket 11 on the top surface of the GPU body 2 to be disassembled, then inserts the screw 2 50 into the mounting hole on the positioning bracket 11 and rotates it clockwise so that the lower end of the screw 2 50 enters the threaded groove 2 49 on the top surface of the GPU body 2 and is tightened, thereby fixing the positioning bracket 11 above the GPU body 2 as the positioning reference for subsequent operations.

[0091] Next, the operator holds the handheld frame 4 of the quick-release fixture, lifts the fixture as a whole, and moves it directly above the faulty GPU body 2. At this time, the lower support arms 8 of the first and second clamping mechanisms are both in the initial retracted position. The distance between the two lower support arms 8 is greater than the width of the GPU body 2, and they are in an open state. The operator adjusts the posture of the fixture so that the connecting block 10 is roughly aligned with the center of the positioning bracket 11, and then slowly moves the fixture downward. As the fixture moves downward, the two sets of lower support arms 8 enter the gap between the adjacent GPU bodies 2 respectively. Since the lower support arms 8 are in the retracted state, their width is small, and they can easily pass through the narrow gap without colliding with the adjacent GPU bodies 2.

[0092] As the fixture continues to move downwards, the connecting block 10 gradually approaches the positioning bracket 11. When the connecting block 10 moves to a certain height, the inclined surface of the lower edge of the front end of the movable locking block 37 contacts the top edge of the positioning bracket 11. Due to the guiding effect of the inclined surface, the top edge of the positioning bracket 11 squeezes the inclined surface of the movable locking block 37, generating an inward horizontal force, causing the movable locking block 37 to overcome the elastic force of the second spring 38 and retract into the connecting groove 36. The operator continues to press down on the handheld frame 4. When the connecting block 10 moves down to the moment when the front end of the movable locking block 37 aligns with the snap-fit ​​hole 35 on the positioning bracket 11, the movable locking block 37 loses the obstruction of the top surface of the positioning bracket 11, and the second spring 38 instantly releases its elastic force, driving the movable locking block 37 to pop out quickly. Its front end accurately inserts into the snap-fit ​​hole 35. At this time, the movable locking block 37 is locked in the snap-fit ​​hole 35, thereby fixing the mounting longitudinal plate 3 and the positioning bracket 11 into one unit, realizing the precise positioning of the fixture and the faulty GPU body 2.

[0093] After positioning, the operator continues to hold the handheld frame 4 with their right hand to maintain the stability of the fixture, while their left hand reaches towards the movable handle 41 and pushes it clockwise. As the movable handle 41 rotates clockwise, it drives the connecting roller 39 to rotate clockwise, which in turn drives the movable support plate 53 to rotate clockwise. Simultaneously, the spring 40 gradually tightens, storing elastic potential energy. The rotation of the movable support plate 53 drives the first movable rod 12 forward and the second movable rod 14 backward. The forward movement of the first movable rod 12 pushes the first connecting plate 13 to slide forward along the limiting slide rail 18, while the backward movement of the second movable rod 14 pushes the second connecting plate 52 to slide backward along the limiting slide rail 18. The first connecting plate 13 and the second connecting plate 52 respectively drive the two lower support arms 8 to move towards each other, gradually approaching the bottom sides of the GPU body 2.

[0094] During the rotation of the movable handle 41, the right side of the movable handle 41 gradually presses against the inclined surface of the positioning block 44, causing the positioning block 44 to retract to the left against the elastic force of the spring 3 46. When the movable handle 41 rotates to its limit position, the two lower support arms 8 are fully closed, and the rubber guard plate 9 is tightly attached to the front and rear sides of the GPU body 2. At the same time, the bottom of the lower support arm 8 supports the bottom surface of the GPU body 2, forming a stable three-point clamping. At this time, the movable locking hole 42 rotates to the position aligned with the positioning block 44. The positioning block 44 loses the obstruction of the right side of the movable handle 41, and the spring 3 46 releases its elastic force instantly, pushing the positioning block 44 into the movable locking hole 42 and automatically locking the position of the movable handle 41. At this time, the operator can release his left hand, and the movable handle 41 will not rotate back. The lower support arm 8 maintains a stable clamping state.

[0095] After the lower support arm 8 is clamped and stabilized, the operator observes the position of the second clamping mechanism. At this time, the two lower support arms 8 located on the bottom surface of the second connecting bracket 6 are exactly to the left of the locking buckle 23 on the PCIE slot 22. The operator pushes the second connecting bracket 6 to the right. The second connecting bracket 6 drives the sliding base 33 to slide to the right and down along the sliding support rod 31 in the connecting hole 30, while compressing the spring 34. The second connecting bracket 6 drives the support plate 7 of the second clamping mechanism and its lower support arm 8 to move to the right and down. During the movement, the lower support arm 8 contacts and squeezes the locking buckle 23, which gradually pushes the locking buckle 23 downward, causing it to rotate downward to unlock. The hook disengages from the groove at the tail of the gold finger of the GPU body 2.

[0096] After the locking clip 23 is unlocked, the operator holds the handle frame 4 and pulls it vertically upwards. Since the lower support arm 8 has firmly clamped the GPU body 2, and the fixture is connected to the GPU body 2 through the positioning component, the GPU body 2 moves upwards along with the fixture when it is pulled up. When the GPU body 2 is completely disengaged from the PCIe slot 22, the operator continues to pull upwards to remove the entire GPU body 2 from the chassis body 1, completing the disassembly operation.

[0097] Installation process: When a new GPU body 2 needs to be installed, the operator first places the positioning bracket 11 on the top surface of the new GPU body 2 and fixes it with screw 250. Then, the tool is placed on the positioning bracket 11, and the hand-held frame 4 is pressed down so that the movable locking block 37 on the connecting block 10 automatically engages with the locking hole 35 of the positioning bracket 11, thus connecting the tool with the GPU body 2. Then, the movable handle 41 is rotated clockwise so that the two lower support arms 8 close together to clamp the bottom of the GPU body 2 and automatically lock.

[0098] The operator lifts the fixture and GPU body 2 using the handheld frame 4, aligns the GPU body 2 with the empty PCIe slot 22 inside the chassis body 1, and slowly inserts it downwards. When the gold fingers of the GPU body 2 are fully inserted into the PCIe slot 22, the locking buckle 23 automatically springs upwards under its own elastic force and locks into the groove at the end of the gold fingers of the GPU body 2, completing the initial fixation.

[0099] Next, the operator places screw 25 on the round hole of connecting lug 24 and rotates it clockwise so that the lower end of screw 25 enters the threaded groove 20 on the top surface of mounting frame 19 and is tightened, thereby fixing the left end of GPU body 2 to mounting frame 19 and further enhancing installation stability.

[0100] Then, the operator pulls the limit block 48 upwards. The limit block 48 pulls the support rod 45 and the positioning block 44 to the left through the rope 47, so that the positioning block 44 exits the movable slot 42. At this time, the spring 40 releases its elasticity, driving the movable handle 41 to automatically rotate counterclockwise to reset, driving the two lower support arms 8 to open and release the GPU body 2.

[0101] Finally, the operator lifts the handle frame 4 upwards, causing the movable latch 37 on the connecting block 10 to disengage from the latching hole 35 of the positioning bracket 11, separating the fixture from the positioning bracket 11. The operator then unscrews the screw 50 on the positioning bracket 11 counterclockwise and removes the positioning bracket 11 from the top surface of the GPU body 2, completing the entire installation process.

[0102] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
