Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted domain controllers, in particular to a vehicle-mounted domain controller and a card removal mechanism thereof. Background Art

[0002] The electrification and intelligent networking of automobiles have driven the evolution of automotive electronic architecture. Traditional automotive distributed electronic architecture has gradually evolved towards multi-domain controller integration and central computing unit architecture. Hardware atomization and upgradeability, software and hardware separation, and SOA have become typical characteristics of future architectures. Based on market demand and technological trends, ICP vehicle-mounted domain controllers came into being.

[0003] Software can be upgraded via OTA, but a set of hardware is unlikely to support the software computing power and resource requirements of a vehicle's 10-year lifespan. Hardware is modular, and low-end hardware is difficult to develop into mid-range or even high-end versions. In order to adapt to rapid technology iterations, personalized customization needs, and improve system maintainability, upgrade convenience, and fault response speed, replaceable and upgradeable board plug-in solutions will become a future requirement. For the entire vehicle domain controller, board replacement or iterative upgrades require that board plug-in be smooth and convenient, but the vehicle domain controller's heat dissipation solution and assembly requirements require that the board be fixed and tightly coordinated with the entire vehicle domain controller.

[0004] In the current existing technology, due to the limitations of heat dissipation performance and the requirements of vibration specifications, the board and the vehicle domain controller water cooling plate must be tightly and firmly matched. Therefore, the traditional plug-in and unplugging method may require greater force, which increases the difficulty of loading and unloading the board, increases the physical stress on the board interface, connector and even the entire structure, and may cause damage to the board. Frequent plugging and unplugging may also destroy the sealing of the water cooling system, affecting the heat dissipation performance and stability of the vehicle domain controller. Utility Model Content

[0005] The purpose of the utility model is to provide a vehicle-mounted domain controller and its card removal mechanism, aiming to solve the technical problems existing in the vehicle-mounted domain controller plug-in and removal solutions in the prior art, such as the difficulty in replacing boards and cards, the low efficiency of replacing boards and cards, and the impact on the heat dissipation and stability of the vehicle-mounted domain controller.

[0006] To solve the above technical problems, the present invention provides an on-vehicle domain controller and a card removal mechanism thereof, wherein the on-vehicle domain controller includes: an integrated frame, the integrated frame having a slot; a card that can be inserted and removed from the slot, two opposing handles movably provided on one side of the card, one end of each handle having a limit block, an inner side of the slot having a limit slot, the limit block being snap-fitted into the limit slot to secure the card;

[0007] The two opposing handles can make the force on the board more evenly distributed compared to a single or unilateral handle, preventing damage to the handle or damage to the board during installation due to stress concentration at the same location. At the same time, the thrust on the board during insertion can be enhanced, making the insertion process smoother, which is beneficial to reducing the difficulty of loading and unloading the board and improving the efficiency of loading and unloading the board. The limit slots and limit blocks cooperate with each other to fix the board on the integrated frame, preventing the board from shaking or even detaching from the integrated frame due to external interference or during equipment operation, which is beneficial to maintaining the stability of the vehicle-mounted domain controller.

[0008] Preferably, a linear guide rail is provided on the slot, a slide groove adapted to the linear guide rail is provided on the board, and the slide groove is slidably mounted on the linear guide rail.

[0009] The linear guides and guide slots work together to limit board positional deviation within the slot, ensuring precise insertion and removal of the board into its designated position. This improves the accuracy and efficiency of board insertion and removal. Once the board is installed, it creates a tighter, more stable connection between the board and the integrated chassis, preventing vibration between the chassis and the board caused by external interference or other disturbances, thereby improving the stability of the vehicle domain controller.

[0010] Preferably, the two handles are rotatable relative to each other, one end of the handle close to the limit block is rotatably connected to the board, the end away from the limit block is provided with a groove and the handle is fixed by a locking piece, the board is provided with a locking hole that cooperates with the locking piece, the two grooves are semicircular structures that can cooperate with each other to form a fixing hole, the locking piece passes through the fixing hole and is detachably connected to the locking hole, so that the two handles are fixed on the board at the same time.

[0011] By opening and closing the two handles relatively, force can be applied evenly to both sides of the board to ensure that the board can be loaded and unloaded smoothly, effectively avoiding damage to the board or integrated frame caused by uneven force on one side, optimizing the loading and unloading and subsequent maintenance processes, and facilitating convenient loading and unloading and secure locking of the board, thereby improving loading and unloading efficiency and reliability of the board; the handle cooperates with the locking parts and grooves to form a stable fixing mechanism. After the board is installed in place, it can effectively resist interference from external and other factors, prevent the loose handle from causing adverse effects on the vehicle domain controller, reduce potential failure risks, and help improve the stability and reliability of the vehicle domain controller.

[0012] When the locking member passes through the fixing hole formed by the two grooves and connects with the lock hole, it can effectively secure the two handles to the board. This reduces the risk of the handles loosening or falling off due to external factors or other interference, improves the stability of the vehicle domain controller, and thus helps to improve the safety and reliability of the vehicle domain controller. The locking member can simultaneously secure or release both handles, simplifying the installation and removal process of the board, reducing damage caused by improper operation, helping to reduce the difficulty of board installation and removal, and improving the stability and service life of the vehicle domain controller.

[0013] In addition, a card extraction mechanism is provided for use with any of the aforementioned vehicle-mounted domain controllers, comprising a support frame, a pulling knob, and a puller. The support frame is detachably mounted on the integrated frame, one end of the pulling knob can movably pass through the support frame and be connected to the board card, and the puller pulls out the board card by pulling the pulling knob.

[0014] The puller, when removing a card using the pull knob, replaces manual operation, increasing the pulling force applied to the card and making the removal process smoother. This helps reduce the difficulty and manual effort involved in loading and unloading the card. During this process, the depth of the connection between the pull knob and the card can be adjusted to control and regulate the card's removal distance, improving the accuracy and stability of card loading and unloading. A support frame assists the puller in applying force to the pull knob, preventing the interaction force from directly acting on the integrated rack or card, or causing the card to disengage from the slot due to excessive pulling force. This helps prevent damage to the card and integrated rack, thereby reducing the impact on the heat dissipation and stability of the vehicle domain controller and mitigating the risk of safety incidents.

[0015] Preferably, the support frame is provided with a guide hole, and the pulling knob can be detachably connected to the board after passing through the guide hole. The top and bottom ends of the support frame are provided with stepped protrusions, and the protrusions abut against the integrated frame.

[0016] The pad is in contact with the side of the integrated frame for plugging and unplugging boards, and its protruding part is in contact with the top and bottom ends of the integrated frame, so that the pad can be completely fitted and abutted against the integrated frame. After the pad is in contact with the integrated frame, the pull-out knob is connected with the board through the guide hole, which is conducive to achieving stable positioning of the pad, preventing position deviation between the pad and the integrated frame due to external interference during loading and unloading, resulting in damage to the board and the integrated frame when loading and unloading the board, which is conducive to improving the accuracy and stability of loading and unloading of the board, and further improving the stability and service life of the vehicle-mounted domain controller.

[0017] It can be understood that the detachable connection between the pulling knob and the board is located between the two handles on the board. When a lock hole is provided on the board, the pulling knob is connected to the lock hole. When there is no lock hole, the position of the lock hole is used as the connection position between the pulling knob and the board, so that when the board is pulled by the pulling knob, the force on all parts of the board is relatively uniform.

[0018] Preferably, the puller includes a main body abutting the pad frame, a connecting rod and a clamping piece movably provided on the main body, and a swing arm rotatably connected to the main body, the connecting rod is fixedly connected to the clamping piece, the clamping piece clamps the pulling knob, and the swing arm drives the connecting rod to move relative to the main body when swinging.

[0019] The swing arm is rotationally connected to the main body and drives the connecting rod and the clamping part. A lever structure of a certain proportion is formed between the swing arm, the main body and the connecting rod, so that the force applied by the swing arm to the connecting rod and the connecting rod to the clamping part increases, thereby increasing the force applied by the clamping part to the pulling knob, making the board removal process smoother, which is beneficial to improving the efficiency and stability of board loading and unloading.

[0020] Preferably, two symmetrical limiting posts are provided on the connecting rod, and the two limiting posts are in contact with the swing arm. When the swing arm swings relative to the main body, the connecting rod is driven to move along the main body through the two limiting posts.

[0021] When the swing arm swings relative to the main body, the two symmetrically arranged limit columns can effectively guide and constrain the movement path of the swing arm, ensuring that it swings in the preset direction and angle, thereby controlling the movement of the connecting rod. When the external force is too large, the limit column can also prevent the swing arm from swinging excessively, and control the puller to pull the pulling knob to pull out the board, which is beneficial to improving the stability and safety of the puller. The swing of the swing arm is converted into linear motion of the connecting rod through the limit column, which is beneficial to reducing energy loss during the movement and improving the smoothness and continuity of the movement. The two symmetrically arranged limit columns can simplify the system structure, reduce the number of components, and help reduce production, processing and maintenance costs. At the same time, they can balance the force of the swing arm on the connecting rod, reduce wear, and help extend the reliability and durability of the puller.

[0022] Preferably, a swing groove is provided adjacent to the main body and the swing arm, and the swing groove is used to limit the swing angle of the swing arm.

[0023] When the swing arm swings relative to the main body, the swing groove and the limit column can effectively limit the swing range of the swing arm to ensure that it swings in the preset direction and angle. When the external force is too large, the limit column can also prevent the swing arm from swinging excessively, and control the puller to pull the pulling knob to pull out the board, which is beneficial to improve the stability and safety of the puller.

[0024] Preferably, the clamping member is a "C"-shaped structure with its opening facing the cushion frame, and one end of the connecting rod is fixedly connected to the clamping member.

[0025] Without the use of complex tools or additional fixtures, the puller and the support bracket can be quickly positioned and secured, significantly reducing assembly time and improving board loading and unloading efficiency. Furthermore, the "C"-shaped connector can surround the pull knob from multiple directions, ensuring that the pull knob does not deflect or rotate when subjected to tension, preventing separation between the pull knob and the connector, and improving the stability and safety of the puller. Furthermore, it can evenly distribute the force applied to the pull knob, avoiding localized stress concentration, thereby reducing deformation or damage to the pull knob and connector due to uneven force and extending their service life.

[0026] In addition, the "C"-shaped clip-on structure has a simple structure and low manufacturing cost, which is conducive to subsequent maintenance. It can adapt to pull-out knobs of various sizes and shapes, has high versatility, and can meet the needs of different scenarios.

[0027] Preferably, the pulling knob is a "T"-shaped structure including a connecting portion and a protruding portion, the connecting portion is threadedly connected to the board clamp, the connecting portion is used to adjust the depth of the pulling knob screwed into the board clamp, the protruding portion is engaged with the clamping piece through the opening, and the protruding portion is used to limit the movement of the clamping piece relative to the main body.

[0028] The pulling knob is divided into two parts, a connecting part and a protruding part, which can simultaneously realize the fixing of the pulling knob pad and the board, and the puller to apply force to the pulling knob. It has a simple structure, low manufacturing cost, and can be changed according to actual needs, which is beneficial to subsequent maintenance; the threaded connection between the connecting part and the board makes the connection between them more stable, improves the stability of board loading and unloading, and when the depth of the connecting plate screwed into the board increases, the stability of the connection between the connecting part and the board will be further increased.

[0029] Without the use of complex tools or additional fixtures, the "T"-shaped pull knob quickly snaps into the clip, significantly reducing assembly time between the puller and the pull knob, and improving board and card loading and unloading efficiency. Furthermore, the protrusion can be tightly surrounded by the clip from multiple directions, ensuring that the pull knob will not deflect or rotate when subjected to tension, preventing separation between the pull knob and the clip. This improves the stability and safety of the puller and enhances the stability of board and card loading and unloading. Furthermore, it evenly distributes the force applied to the pull knob, avoiding localized stress concentration, thereby reducing deformation or damage to the pull knob and clip due to uneven force, and extending their service life.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] The card's handle structure has been optimized. Two opposing handles apply a strong and even force to the card, allowing for easy insertion and removal of the card when the handles are open, improving smoothness and convenience in loading and unloading. The stoppers on the handles work in tandem with the stop slots on the integrated frame to secure the card securely to the integrated frame, minimizing the impact of external interference or vibration during operation on the heat dissipation and stability of the vehicle domain controller.

[0032] A new card extraction mechanism for the adapter board is added, including a pad, a pull-out knob, and a puller that pulls the board through the pull-out knob. This can apply a large and uniform force to the board, thereby pulling out the board smoothly and accurately, making the board extraction process smoother, which is conducive to reducing the difficulty and labor intensity of loading and unloading the board, improving the efficiency of board disassembly, reducing damage to the board and integrated frame, and further helping to reduce the impact of board loading and unloading on the heat dissipation and stability of the vehicle-mounted domain controller.

DETAILED DESCRIPTION

[0040] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0041] In the description of the present invention, it should be understood that terms such as "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0043] In this embodiment, please refer to Figures 1 to 4 As shown, the present invention provides a vehicle-mounted domain controller, which includes an integrated frame 10 provided with a plurality of slots 11 and a board 20 that can be plugged into the slots 11.

[0044] Two opposing handles 21 are provided on one side of the card 20. The handles 21 can be opened or closed relative to each other. The connection between the two handles 21 and the card 20 is located near two adjacent corners of the card 20. When the handles 21 are opened to a position perpendicular to one side of the card 20, the pushing or pulling force on both sides of the card 20 is maximized, making it easier to slide the card 20 into or out of the slot 11. A stop block 211 is provided at one end of the handle 21. Two stop slots 15 are provided on the inner walls of the slot 11. The stop slots 15 are located near the connection between the handles 21 and the card 20. When the card 20 is fully inserted into the slot 11 and the handles 21 have not yet closed onto the card 20, the stop blocks 211 can cooperate with the stop slots 15. When the handles 21 are closed onto the card 20, the stop slots 15 can abut the stop blocks 211, securing the card 20 in the slot 11.

[0045] It can be understood that after the slot 11 is installed with the board 20, when there is external interference or the device is running, there will be no vibration or other relative position changes between the slot 11 and the board 20 that affect the stability of the vehicle domain controller; the connection between the two handles 21 and the board 20 is respectively located near the two adjacent corners of the board 20, and these two corners are located on the side where the two handles 21 are installed, that is, on the entrance side of the slot 11 of the integrated frame 10, so the limit block 211 is set at one end close to the connection; when the two handles 21 are covered on the board 20, their opposite ends are fixed on the board 20; the number of card slots 32 of the pad 30 is the same as or less than the number of slots 11 on the integrated frame 10; the connection depth between the pull-out knob 35 and the board 20 is adjustable.

[0046] In addition, a plurality of heat-conducting materials 13 may be provided on the water-cooling plate 12 to improve the heat dissipation performance of the board 20 , so that the board 20 can be more tightly installed in the slot 11 , thereby improving the heat dissipation performance and stability of the vehicle-mounted domain controller.

[0047] In this embodiment, please refer to Figure 3 and Figure 4 As shown, linear guide rails 14 are provided on the inner walls on both sides of the slot 11, and sliding grooves 212 adapted to the linear guide rails 14 are provided on both sides of the board 20. In the process of inserting and removing the board 20 from the slot 11, the board 20 not only slides along the inner wall of the slot 11, but also slides along the linear guide rails 14. It can be understood that the linear guide rails 14 extend from the entrance of the slot 11 toward the inside of the slot 11, and the linear guide rails 14 on both sides are parallel.

[0048] Furthermore, the linear guide rails 14 and the slide grooves 212 can be arranged in opposite directions, that is, the linear guide rails 14 are arranged on both sides of the board 20, and the slide grooves 212 are arranged on the inner walls of the slot 11. Furthermore, to prevent vibration between the board 20 and the slot 11 and further improve the stability of the vehicle-mounted domain controller, multiple parallel linear guide rails 14 and slide grooves 212 can be provided.

[0049] In this embodiment, please refer to Figure 3 and Figure 4 As shown, the two handles 21 can be rotated relative to each other to open and close on the board 20, and the ends of the two handles 21 near the limit block 211 are rotatably connected to the board 20. It can be understood that, consistent with the above, the connection is located near two adjacent corners of the board 20, and these two corners are located on the side where the two handles 21 are installed, that is, on the entrance side of the slot 11 of the integrated frame 10. When the handle 21 is opened to be perpendicular to one side of the board 20, the push or pull force on both sides of the board 20 can be maximized, which makes it easier to slide the board 20 into or out of the slot 11.

[0050] A groove 213 is provided at the end away from the limit block 211, and a locking hole 22 is provided on the board 20. When the handle 21 is covered on the handle 21, the groove 213 and the locking hole 22 are on the same axis, and the handle 21 can be fixed by cooperating with the locking hole 22 and the groove 213 through a locking member. The two grooves 213 are semicircular structures that can cooperate with each other to form a fixing hole 214. The locking member passes through the fixing hole 214 and is detachably connected to the locking hole 22, so that the two handles 21 are fixed on the board 20 at the same time.

[0051] It can be understood that independent grooves can be set on the two handles 21 respectively, and accordingly, two locking holes 22 opposite to the two independent grooves need to be set on the board 20; when the two handles 21 are covered on the board 20, the grooves 213 at both ends can abut against each other and form a fixing hole 214. The shape of the fixing hole 214 and the structure of the end are determined by the groove 213, but it is necessary to meet the requirement that the locking member can pass through the fixing hole 214 and be detachably connected to the locking hole 22, so that the two handles 21 are fixed on the board 20 at the same time. Therefore, under the above conditions, the grooves 213 at the opposite ends of the handles 21 can be regular or irregular shapes, and the structural cooperation of the two handles 21 can be abutting or overlapping up and down, etc.

[0052] In addition, the handle 21 can also be set as a frame structure, which is beneficial to reducing production and processing costs and facilitating the application of force to the handle 21.

[0053] In this embodiment, please refer to Figure 1 and Figure 5As shown, the card extraction mechanism includes a support frame 30, a pull knob 35, and a puller 40. The support frame 30 is detachably connected to the integrated frame 10. The support frame 30 is a rack with a "C"-shaped outer plate for guiding and accommodating the board 20. It is provided with a plurality of card slots 32 for accommodating the board 20. The card slots 32 are consistent with the specifications of the slots 11. When the support frame 30 is installed on the integrated frame 10, the card slots 32 are opposite to the slots 11. One end of the pull knob 35 can movably pass through the support frame 30 and connect to the board 20. The puller 40 pulls the board 20 out along the slot 11 and slides it into the card slot 32 by rotating the other end of the pull knob 35.

[0054] It can be understood that the "C"-shaped structure of the pad 30 can position the height of the pad 30 relative to the integrated frame 10, and then by pulling the knob 34 through the pad 30 and connecting it to the board 20, the relative position of the pad 30 and the integrated frame 10 is completely locked, so that the card slot 32 is opposite to the slot 11, and the board 20 can be pulled out along the slot 11 and slid into the card slot 32.

[0055] For details, please refer to Figure 1 and Figure 5 As shown, a guide hole 33 is provided on the support frame 30, and the pull knob 35 can be detachably connected to the lock hole 22 after passing through the guide hole 33. The top and bottom ends of the support frame 30 are provided with stepped protrusions 31, and the protrusions 31 abut against the top and bottom water-cooling plates 12 of the integrated frame 10 through the stepped grooves 34 formed by the steps. The guide hole 33 and the protrusions 31 jointly realize the installation of the support frame 30 to the specified position of the integrated frame 10.

[0056] It can be understood that the number of guide holes 33 matches the number of card slots 32. After the pad 30 is installed on the integrated frame 10, when the board 20 is provided with a locking hole 22, the guide hole 33 and the locking hole 22 should be coaxial, which is used to assist in positioning the pad 30 in the horizontal installation position on the integrated frame 10, so that the board 20 can be more accurately pulled out by the puller 40 through the pulling knob 35 to slide into the card slot 32. When it is not stated that the board 20 is provided with a locking hole 22, the pulling knob 35 and the board 20 can be set with reference to the position of the locking hole 22. the stepped groove 34 of the protruding portion 31 abuts the water-cooling plates 12 at the top and bottom ends of the integrated rack 10, assisting in positioning the mounting position of the pad 30 on the integrated rack 10; the stepped groove 34 abuts the position of the card slot 32 on the integrated rack 10, and the space constrained by it for inserting the board 20 should be consistent with the space constrained by the slot 11, so that the board 20 can be smoothly pulled out onto the pad 30 and the card slot 32 bears part of the weight, avoiding the occurrence of overhanging and causing stress concentration on the pulling knob 35 and its connection with the board 20.

[0057] More specifically, please refer to Figure 5As shown, the puller 40 includes a main body 41 that abuts the support frame 30, a connecting rod 44 and a clamping member 45 movably mounted on the main body 41, and a swing arm 42 rotatably connected to the main body 41. The main body 41 has an opening structure 411 at one end close to the support frame 30 and a gripping plate 43 at the other end away from the support frame 30. The connecting rod 44 passes through the main body 41 and is fixedly connected to a clamping member 45 located on the opening structure 411. The clamping member 45 is used to clamp the pulling knob 35. The swing arm 42 is approximately a "Y"-shaped structure, with a "V"-shaped curved portion 422 rotatably connected to both sides of the end of the main body 41 away from the support frame 30, and this position is biased towards the top of the main body 41. The "I"-shaped gripping portion 421 and the gripping plate 43 jointly grip the puller 40. The swing arm 42 drives the clamping member 45 to move relative to the main body 41 via the connecting rod 44, forming a lever structure among the swing arm 42, the connecting rod 44, and the main body 41.

[0058] It can be understood that the opening size of the opening structure 411 is consistent with that of the clamping member 45 , and while being able to accommodate the clamping member 45 , the clamping member 45 will not shake relative to the main body 41 when moving along the opening structure 411 .

[0059] In addition, the connecting rod and the clamping member 45 can also be an integrally formed structure, and the swing arm 42 can also be an "H"-shaped structure, so as to meet the above functions.

[0060] More specifically, two limit columns 441 are provided on the connecting rod near one end of the swing arm 42. The two limit columns 441 are symmetrically arranged and extend to the outside of the swing arm 42 on both sides of the main body 41. The cylindrical surfaces of the two limit columns 441 are both in contact with one side of the swing arm 42. When the swing arm 42 swings relative to the main body 41, it can be converted into linear motion of the driving connecting rod 44 along the main body 41 through the two limit columns 441.

[0061] It can be understood that the swing arm 42, the main body 41, and the connecting rod 44 should conform to the principle of leverage, and further, can be set as a force-saving lever; the swing arm 42 drives the connecting rod 44 through the limit column 441 by squeezing the limit column 441 by the swing arm 42. Therefore, in order to achieve a smooth and force-saving process, the part of the swing arm 42 that abuts against the limit column 441 can be set as a curved surface structure with a concave surface facing the limit column 441.

[0062] In addition, the abutting end of the swing arm 42 and the limiting column 441 can also be set to other shapes and structures to meet the function of the above-mentioned swing arm 42.

[0063] More specifically, a swing groove 412 is provided adjacent to the main body 41 and the swing arm 42. It can be understood that the swing groove 412 includes the "V"-shaped bending portion 422 of the swing arm 42, which can meet the swing of the swing arm 42 within a certain range.

[0064] In addition, the shape and structure of the swing slot 412 can also be changed with the shape and structure of the swing arm 42 so as to satisfy the swinging of the swing arm 42 within a certain range.

[0065] More specifically, please refer to Figure 5 As shown, the clamping member 45 is a "C"-shaped structure with its opening facing the pad frame 30. The clamping member 45 clamps the pulling knob 35 to the inside of the clamping member 45 through the opening 451 of the "C"-shaped structure. One end of the connecting rod 44 is fixedly connected to the clamping member 45. When the connecting rod 44 is pulled by the swing arm 42, the clamping member 45 also pulls the pulling knob 35, but the main body 41 abutting against the pad frame 30 is exerted with a reverse force by the pad frame 30, which offsets the force of the clamping member 45 pulling the pulling knob 35, so that the positions of the puller 40 and the pad frame remain relatively stationary when the clamping member 45 pulls the pulling knob 35.

[0066] It can be understood that the opening 451 of the "C"-shaped structure can be set horizontally or vertically, and the shape and structure of the clamping member 45 can also be changed so that the pulling knob 35 can be quickly clamped into the clamping member 45 and the clamping member 45 can be moved along the opening structure 411 of the main body 41.

[0067] More specifically, please refer to Figure 4 and Figure 5 As shown, the pull knob 35 is a "T"-shaped structure comprising a connecting portion and a protrusion 351. The connecting portion passes through the guide hole 33 and is threadedly connected to the board 20, forming a detachable connection between the pull knob 35 and the board 20, and between the support frame 30 and the board 20. It is understandable that the depth to which the connecting portion is screwed into the board 20 is adjustable; the "T"-shaped structure of the protrusion 351 is inserted into the opening 451 of the "C"-shaped structure of the clamping member 45, so that the protrusion 351 fully contacts the interior of the opening 451 of the "C"-shaped structure, thereby improving the stability of the connection between the pull knob 35 and the clamping member 45 and limiting the movement of the clamping member 45 relative to the main body 41, so that the clamping member 45 can fully pull the pull knob 35 to remove the board 20.

[0068] In addition, the pulling knob 35 can also be of other shapes or structures, such as the protrusion 351 is a hemisphere, a cylinder, etc., so that the pulling knob 35 can be quickly snapped into the clamping member 45 and the movement of the clamping member 45 relative to the main body 41 can be restricted.

[0069] Furthermore, a limiting portion may be provided on one side of the protrusion 351 for abutting against one side of the clamping member 45 , thereby facilitating the quick clamping of the pull-out knob 35 and preventing the pull-out knob 35 from being separated from the clamping member 45 .

[0070] The specific application process of this utility model is as follows:

[0071] How to use the puller 40: Snap the pulling knob 35 into the clamping part 45 from the opening 451, hold the grip plate 43 and apply force to the swing arm 42, the swing arm 42 rotates relative to the main body 41, so that the limiting column 441 abutting against the swing arm 42 drives the connecting rod 44 to move on the main body 41, and the connecting rod 44 drives the clamping part 45 to abut against the pulling knob 35. The force between the clamping part 45 and the pulling knob 35 is balanced by the force between the main body 41 and the pad 30. Then the clamping part 45 pulls the pulling knob 35 to pull out the board 20 and slide it into the slot 32.

[0072] When board 20 is inserted:

[0073] When installing the board 20, open the two handles 21 until the handles 21 and the board 20 are at a certain angle or vertical, align the board 20 with the slot 11 and the linear guide 14, push the handles 21, and make the board 20 slide along the linear guide 14 in the slot 11. After it is fully inserted into the slot 11, cover the handles 21 onto the board 20. The limit blocks 211 of the handles 21 cooperate with the limit slots 15 of the integrated frame 10 to fix the board 20. The grooves 213 of the two handles 21 cooperate to form a fixing hole 214. Then use the locking piece to cooperate with the fixing hole 214 and the lock hole 22 to fix the two handles 21 on the board 20 to complete the assembly.

[0074] When removing board 20:

[0075] Remove the locking pieces for fixing the two handles 21 on the board 20 to be removed, open the handles 21 of these boards 20, so that the support frame 30 can abut against the integrated frame 10, and the stepped groove 34 abuts against the top and bottom water-cooling plates 12 of the integrated frame 10. The guide holes 33 of the support frame 30 need to be aligned with the lock holes 22 of the board 20 to be removed. Use the pull knob 35 to pass through the support frame 30 and connect it with the lock hole 22 on the board 20 to be removed. Adjust the pull knob 35 is screwed into the lock hole 22 to the depth, the pulling knob 35 is clamped into the clamping part 45 on the puller 40, and the puller 40 is moved to pull the knob 35, so that the board 20 to be removed is pulled out from the slot 11 along the slot 11 and the linear guide 14 and slides into the clamping slot 32 of the support frame 30, and the support frame 30 is removed. The two handles 21 on the board 20 to be removed are pulled out completely from the slot 11 along the slot 11 and the linear guide 14 to complete the disassembly.
