Description

Technical Field

[0001] This invention relates to the field of server technology, and in particular to a support and protection device. Background Technology

[0002] With the development of information technology, electronic products are widely used in various industries, and servers, as infrastructure, are developing vigorously in multiple fields such as data storage, information exchange, and intelligent computing.

[0003] Currently, the motherboard, as a core component of a server, provides crucial support for the server's logical operations, storage, expansion functions, and management. Because motherboards may experience vibration, drops, and collisions during transportation, significant deformation can occur, affecting the reliability of the surface components. Therefore, effective support and protection are essential during transport. However, currently, motherboards are primarily transported individually in cardboard boxes with foam padding. Different motherboards require different shipping packaging, resulting in a complex and varied array of packaging options that cannot guarantee effective support and protection for the motherboard. Summary of the Invention

[0004] The purpose of this invention is to provide a support and protection device that solves the technical problem of the wide variety of circuit board packaging and the inability to guarantee effective support and protection for the circuit boards.

[0005] To achieve the above objectives, the present invention provides a support and protection device, comprising:

[0006] The frame includes a support plate and side plates located on both sides of the support plate;

[0007] The first limiting module is movably connected to the side plate and is used to abut against the board in the first direction to limit the board in the first direction;

[0008] The second limiting module is movably connected to the support plate and is used to clamp the board along the second and third directions to limit the board in a plane perpendicular to the first direction.

[0009] In some respects, the side plate is provided with a first moving track, which extends along a second direction;

[0010] The first limit module includes:

[0011] The first movable locking component is movably connected to the first movable track for moving relative to the first movable track in a second direction, and for fixing to the first movable track after the position in the second direction is adjusted.

[0012] The second movable locking component is movably connected to the first movable locking component, and is used to move relative to the first movable locking component in a third direction, and to be fixed to the first movable locking component after the position in the third direction has been adjusted.

[0013] The first limiting component is movably connected to the second movable locking component, and is used to move relative to the second movable locking component in a first direction to abut against the plate, and is used to fix to the second movable locking component after the position in the first direction is adjusted.

[0014] In other respects, the first movable locking assembly includes:

[0015] A movable rod with a first slider, the first slider being slidably engaged with a first movable track, the movable rod having a second movable track extending in a third direction;

[0016] The first locking component is threadedly connected to the moving rod and is used to fix the moving rod to the first moving track after the position of the moving rod has been adjusted.

[0017] In other respects, the second movable locking assembly includes:

[0018] A positioning rod with a second slider, the second slider being slidably engaged with a second moving track, and the positioning rod having positioning holes spaced apart along a first direction;

[0019] Two second locking fasteners are threadedly connected to the positioning rod and are located on both sides of the second slider along the first direction, respectively, to fix the positioning rod to the second moving track after the positioning rod position is adjusted.

[0020] In other respects, the first limiting component includes:

[0021] A pressure block with a sleeve is used to abut against the plate, and the sleeve is fitted onto the positioning rod;

[0022] The positioning pin is located on the sleeve and is used to embed into the positioning hole so that the pressure block is fixed to the positioning rod.

[0023] In other aspects, the positioning pin is a resilient reset pin, which is an integral structure with the sleeve. The resilient reset pin is used to move the pressure block relative to the positioning rod when it is pulled out, and to embed into the positioning hole to fix the pressure block to the positioning rod when it is reset.

[0024] In other aspects, the first moving track is stepped and includes a first channel and a second channel that are interconnected. The width of the first channel is smaller than the width of the second channel. The moving rod passes through the first channel, and the first slider is slidably embedded in the second channel.

[0025] In other respects, the support plate is provided with a third moving track and a fourth moving track, which extend along a second direction and a third direction, respectively;

[0026] The second limiting module includes a second limiting component and a third limiting component, which slide in cooperation with the third moving track and the fourth moving track, respectively.

[0027] Both the second and third limiting components include a third slider with a stud. The third slider is slidably engaged with the support plate. The stud is threadedly connected to a third locking fastener. The diameter of the third locking fastener is larger than the width of the third slider. A limiting plate is provided on the side of the third slider away from the third locking fastener. The width of the limiting plate is larger than the width of the third slider. The third locking fastener is used to fix the third slider to the support plate after the position of the third slider is adjusted. The third slider is connected to a limiting block. The limiting block and the third locking fastener are located on the same side of the third slider. The limiting block is used to abut against the outer wall of the plate to clamp the plate.

[0028] Both the third and fourth moving tracks are stepped, and each includes a third and fourth interconnected channel. The width of the third channel is smaller than that of the fourth channel. The third slider is slidably fitted into the third channel, the limiting plate abuts against the bottom of the fourth channel, and the third locking fastener abuts against the inner wall of the support plate. This allows the third slider to be fixed to the support plate by the clamping force of the third locking fastener and the limiting plate after the position is adjusted.

[0029] In other aspects, the sidewall of the limiting block is provided with an elastic buffer pad, which is used to contact and abut against the outer sidewall of the board, and the elastic buffer pad is provided with a groove, which is used to accommodate the outer sidewall of the board.

[0030] In other aspects, the support and protection device also includes a cover plate, which is fixed to the frame and the cover plate and the frame together form a sealed cavity, in which the plate is accommodated.

[0031] Compared to the background technology described above, the support and protection device provided in this embodiment of the invention includes a frame, a first limiting module, and a second limiting module. The frame includes a support plate and side plates disposed on both sides of the support plate. The first limiting module is movably connected to the side plates and is used to abut against a plate in a first direction to limit the plate in that direction. The second limiting module is movably connected to the support plate and is used to clamp the plate in a second and a third direction to limit the plate in a plane perpendicular to the first direction. The first, second, and third directions are perpendicular to each other.

[0032] As can be seen, during assembly, the circuit board is first placed on the support plate of the frame. Then, the second limiting module moves relative to the support plate to clamp the circuit board along the second and third directions, respectively, thus limiting the circuit board in a plane perpendicular to the first direction. Afterward, the first limiting module moves relative to the side plate and clamps the circuit board along the first direction, thus limiting the circuit board in the first direction. This achieves the purpose of fixing the circuit board and providing stable support and protection.

[0033] The beneficial effects of this support and protection device mainly include: This invention develops an adjustable support and protection device for single-package transportation of circuit boards, which has arbitrary horizontal clamping and vertical adjustment functions. It is suitable for motherboards or PCBs of servers and many electronic products. The first and second limit modules of this device are flexibly adjustable, and one set of devices can realize the single-package transportation of circuit boards of different sizes and functions, with strong versatility and adaptability. Furthermore, this device is reusable, reducing packaging manufacturing costs. At the same time, this device can restrict six degrees of freedom of the circuit board, providing strong support and protection, effectively improving the reliability of motherboard support and protection during transportation, and solving the technical problem of complex and diverse circuit board packaging that cannot guarantee effective support and protection for the circuit boards.

[0053] 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.

[0054] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] Please see Figure 1 and Figure 2 The support and protection device provided in this embodiment of the invention includes a frame 10, a first limiting module 20, and a second limiting module 30.

[0056] Please refer to the following: Figure 3 The frame 10 is specifically a rectangular frame with an opening at the top. The frame 10 includes a support plate 11 and side plates 12 located on the left and right sides of the support plate 11. The support plate 11 serves to support the plate clip and the second limiting module 30, while the side plates 12 on both sides support the first limiting module 20. In addition, the frame 10 also includes end plates located at the upper and lower ends of the support plate 11. The two end plates and the two side plates 12 together form a enclosure structure around the support plate 11. The support plate 11, the two end plates, and the two side plates 12 together form an inner cavity for accommodating the plate clip 50.

[0057] The first limiting module 20 is movably connected to the side plate 12. The first limiting module 20 is used to abut against the board 50 along a first direction to limit the board 50 in the first direction. This first direction can be as follows: Figure 3 The Z-axis direction shown is the vertical direction. In this way, by arbitrarily adjusting the first limiting module 20 in the vertical direction, the purpose of limiting the plate in the vertical direction can be achieved.

[0058] The second limiting module 30 is movably connected to the support plate 11. The second limiting module 30 is used to clamp the board 50 along a second direction and a third direction to limit the board 50 in a plane perpendicular to the first direction. The first direction, the second direction, and the third direction are perpendicular to each other. The second direction can be as follows: Figure 3 The X-axis direction shown can be represented as follows: Figure 3 The Y-axis direction shown, which is also the second direction and the third direction, are two mutually perpendicular directions in the horizontal plane. In this way, by arbitrarily adjusting the second limiting module 30 in the horizontal plane, the purpose of limiting the plate in the horizontal plane can be achieved.

[0059] As can be seen, during assembly, the board 50 is first placed on the support plate 11 of the frame 10, and then the second limiting module 30 moves relative to the support plate 11 to clamp the board 50 along the second direction and the third direction respectively, thereby limiting the board 50 in the plane perpendicular to the first direction. After that, the first limiting module 20 moves relative to the side plate 12 and clamps the board 50 along the first direction, thereby limiting the board 50 in the first direction.

[0060] This achieves the purpose of fixing the board 50 and providing stable support and protection for the board 50.

[0061] It should be noted that board 50 can be a motherboard or a PCB board. Taking the motherboard as an example, as a core component of the server, the motherboard provides crucial support for the server's logical operations, storage, expansion functions, and management. Since motherboards may experience vibration, drops, or collisions during transportation, significant deformation can occur, affecting the reliability of the surface components. Therefore, protective support during transportation is crucial for the strength and reliability of the motherboard. Currently, motherboards are mainly transported individually in cardboard boxes with foam padding, resulting in a wide variety of packaging options that fail to provide effective support and protection.

[0062] To address this issue, this invention develops an adjustable support and protection device for single-package transportation of circuit boards 50. It features arbitrary horizontal clamping and vertical adjustment, making it suitable for motherboards or PCBs of servers and numerous electronic products. The first limiting module 20 and the second limiting module 30 of this device are flexibly adjustable. One set of devices can achieve single-package transportation of circuit boards 50 of different sizes and functions, exhibiting strong versatility and adaptability. Furthermore, this device is reusable, reducing packaging manufacturing costs. Simultaneously, this device can restrict six degrees of freedom of the circuit board 50, providing strong support and protection, effectively improving the reliability of motherboard support and protection during transportation, and solving the technical problem of the diverse and complex packaging of circuit boards 50, which could not guarantee effective support and protection for the circuit boards 50.

[0063] Please refer to the following: Figure 4 and Figure 5 The side plate 12 is provided with a first moving track 121, which extends along a second direction. The first limiting module 20 is used to move along the first moving track 121 so as to adjust the position of the first limiting module 20 in the second direction according to the position of the board 50.

[0064] Please refer to the following: Figure 6 The first limiting module 20 includes a first movable locking component 21, a second movable locking component 22 and a first limiting component 23.

[0065] The first movable locking component 21 is movably connected to the first movable track 121. The first movable locking component 21 is used to move relative to the first movable track 121 along a second direction, and is fixed to the first movable track 121 after the position adjustment in the second direction is completed. The second movable locking component 22 is movably connected to the first movable locking component 21. The second movable locking component 22 is used to move relative to the first movable locking component 21 along a third direction, and is fixed to the first movable locking component 21 after the position adjustment in the third direction is completed. The first limiting component 23 is movably connected to the second movable locking component 22. The first limiting component 23 is used to move relative to the second movable locking component 22 along a first direction to abut against the plate 50, and is fixed to the second movable locking component 22 after the position adjustment in the first direction is completed.

[0066] It is understood that the present invention employs a mobile locking system with multi-level movement and fixing functions to limit and fix the board 50. Specifically, as the first-level moving and fixing components, the first moving locking component 21 is movably connected to the first moving track 121. The connection between the first moving locking component 21 and the first moving track 121 can be achieved through structures such as sliders and guide rails, allowing the first moving locking component 21 to slide freely on the first moving track 121. The moving direction of the first moving locking component 21 is along a second direction relative to the first moving track 121. After the position of the first moving locking component 21 in the second direction is adjusted, it can be fixed to the first moving track 121, for example, through fixing devices such as locking screws and buckles, to ensure that the first moving locking component 21 will not shift after being adjusted to the appropriate position. The second moving locking component 22 is movably connected to the first moving locking component 21. The connection between the second moving locking component 22 and the first moving locking component 21 allows the second moving locking component 22 to move on the first moving locking component 21. The moving direction is along a third direction relative to the first moving locking component 21. After the second moving locking component 22 is adjusted to its position in the third direction, it can be fixed to the first moving locking component 21. The first limiting component 23 is movably connected to the second moving locking component 22. The connection between the first limiting component 23 and the second moving locking component 22 allows the first limiting component 23 to be adjusted in position on the second moving locking component 22. The moving direction of the first limiting component 23 is along a first direction relative to the second moving locking component 22 to abut against the board 50. Through this movement, the first limiting component 23 can accurately contact the board 50, playing a limiting role and preventing the board 50 from shaking or deviating in position during transportation. After the position of the first limiting component 23 in the first direction is adjusted, it can be fixed to the second moving locking component 22. After fixing, the first limiting component 23 can stably limit the board 50, ensuring that the board 50 remains in the correct position during subsequent use.

[0067] The design of the multi-level moving locking component system described above enables precise positioning and fixation of the board 50 in the first direction based on its position.

[0068] Please refer to the following: Figure 7The first movable locking assembly 21 includes a first locking member 213 and a movable rod 211 with a first slider 212. The first slider 212 is slidably engaged with a first movable track 121 and can slide relative to the first movable track 121 along a second direction. The movable rod 211 has a second movable track 2111 extending along a third direction. The first locking member 213 is threadedly connected to the movable rod 211 and is used to fix the movable rod 211 to the first movable track 121 after the position of the movable rod 211 has been adjusted.

[0069] For example, the first locking device 213 can be a nut or a hand-operated stud structure with an internal threaded hole. After the position of the moving rod 211 in the second direction is adjusted, the moving rod 211 will not continue to move after being adjusted to the appropriate position by rotating the hand-operated stud structure relative to the moving rod 211.

[0070] As can be seen, the first locking device 213 and the first slider 212 are located on the left and right sides of the first moving track 121, respectively. After the first slider 212 slides to the designated position relative to the first moving track 121, the first locking device 213 is tightened by screw thread. In this way, the first locking device 213 and the first slider 212 use the clamping force on the first moving track 121 to achieve the purpose of fixing the moving rod 211 to the first moving track 121.

[0071] Please refer to the following: Figure 8 The second movable locking assembly 22 includes two second locking members 223 and a positioning rod 221 with a second slider 222. The second slider 222 is slidably engaged with the second movable track 2111 and can slide relative to the second movable track 2111 along a third direction. The positioning rod 221 has positioning holes 2211 spaced apart along a first direction. Both second locking members 223 are threadedly connected to the positioning rod 221. The two second locking members 223 are located on opposite sides of the second slider 222 along the first direction and are used to fix the positioning rod 221 to the second movable track 2111 after the positioning rod 221 has been adjusted.

[0072] For example, the second locking device 223 can also be a hand-operated stud structure with an internal threaded hole. After the positioning rod 221 with the second slider 222 is adjusted to the third-direction position, the positioning rod 221 will not continue to move after being adjusted to the appropriate position by rotating the hand-operated stud structure relative to the positioning rod 221.

[0073] As can be seen, the two second locking fasteners 223 are located on the upper and lower sides of the second slider 222 respectively. After the second slider 222 slides to the designated position relative to the second moving track 2111, the upper second locking fastener 223 is tightened by screw thread. In this way, the two second locking fasteners 223 use the clamping force on the second moving track 2111 to achieve the purpose of fixing the positioning rod 221 to the second moving track 2111.

[0074] In some embodiments, the first limiting component 23 includes a positioning pin 233 and a pressure block 231 with a sleeve 232. The pressure block 231 is used to abut against the plate 50, and the sleeve 232 is sleeved on the positioning rod 221. The positioning pin 233 is disposed on the sleeve 232 and is used to be embedded in the positioning hole 2211 so that the pressure block 231 is fixed to the positioning rod 221.

[0075] The pressure block 231 acts as a positioning element of the contact plate 50. The pressure block 231 can be adjusted arbitrarily along the first direction (i.e., the vertical direction). This allows the position of the pressure block 231 in the vertical direction to be determined based on the position of the plate 50 or the surface devices on the plate 50. After adjusting the height of the pressure block 231, the positioning pin 233 is inserted into the positioning hole 2211 to fix the pressure block 231 to the positioning rod 221.

[0076] In some embodiments, the positioning pin 233 is an elastic reset pin, which is integral with the sleeve 232. The elastic reset pin is used to move the pressure block 231 relative to the positioning rod 221 when it is pulled out, and to embed into the positioning hole 2211 when it is reset, so that the pressure block 231 is fixed to the positioning rod 221.

[0077] It should be noted that the positioning rod 221 has multiple small holes (positioning holes 2211) for matching the positioning pins 233 to achieve vertical positioning of the pressure block 231. The positioning pins 233 are elastic reset pins. After the elastic reset pins are pulled out, the pressure block 231 can move up and down. After releasing, the elastic reset pins fall into the small holes under the action of elasticity, thus achieving vertical positioning of the pressure block 231. The pressure block 231 is a hard rubber structure used to press down on the components on the motherboard surface, such as the PCB, memory slots, heat sinks, handles, etc. Depending on the size of the motherboard, 2 to 5 first limiting components 23 can be used to limit the vertical positioning of the motherboard.

[0078] Of course, depending on actual needs, five first movable locking components 21 can be arranged at intervals in the second direction, and each first movable locking component 21 can be provided with at least two second movable locking components 22 and a first limiting component 23. For example, one first movable locking component 21 can be provided with three second movable locking components 22 and a first limiting component 23, so that it can abut against three different positions on the motherboard located below the first movable locking component 21. Another first movable locking component 21 can be provided with two second movable locking components 22 and a first limiting component 23, so that it can abut against two different positions on the motherboard located below the first movable locking component 21.

[0079] Please refer to the following: Figure 9 The first moving track 121 is stepped and includes a first channel 1211 and a second channel 1212 that are connected to each other. The width of the first channel 1211 is smaller than the width of the second channel 1212. The moving rod 211 passes through the first channel 1211 and the first slider 212 is slidably embedded in the second channel 1212.

[0080] As can be seen, the second channel 1212 is located outside the corresponding first channel 1211. The size and structure of the first slider 212 are adapted to the second channel 1212. After installation, the first slider 212 can be accommodated in the second channel 1212 and slide along the extension direction of the second channel 1212. The first locking fastener 213 is located inside the first slider 212. After the first slider 212 slides to the designated position relative to the second channel 1212, the first locking fastener 213 is tightened by screw thread. In this way, the first locking fastener 213 abuts against the inner side wall of the corresponding side plate 12. The first locking fastener 213 and the first slider 212 use the clamping force on the first moving track 121 to achieve the purpose of fixing the moving rod 211 to the first moving track 121.

[0081] In some embodiments, the support plate 11 is provided with a third moving track 111 and a fourth moving track 112, which extend along a second direction and a third direction, respectively; correspondingly, the second limiting module 30 includes a second limiting component 31 and a third limiting component 32, which slide in cooperation with the third moving track 111 and the fourth moving track 112, respectively.

[0082] Please refer to the following: Figure 10Both the second limiting component 31 and the third limiting component 32 include a third slider 311 with a stud 312. The third slider 311 is slidably engaged with the support plate 11. The stud 312 is threadedly connected to a third locking fastener 313. The third locking fastener 313 can also be a hand-cranked stud structure with an internal threaded hole. The diameter of the third locking fastener 313 is larger than the width of the third slider 311. A limiting plate 314 is provided on the side of the third slider 311 away from the third locking fastener 313. The width of the limiting plate 314 is larger than the width of the third slider 311. The third locking fastener 313 is used to fix the third slider 311 to the support plate 11 after the position of the third slider 311 is adjusted. The third slider 311 is connected to a limiting block 315. The limiting block 315 and the third locking fastener 313 are located on the same side of the third slider 311. The limiting block 315 is used to abut against the outer wall of the plate 50 to clamp the plate 50.

[0083] As can be seen, the third locking fastener 313 and the corresponding limiting plate 314 are located on the upper and lower sides of the third slider 311, respectively. After the third slider 311 slides relative to the support plate 11 to the designated position, the third locking fastener 313 is tightened by screw thread. In this way, the third locking fastener 313 and the corresponding limiting plate 314 use the clamping force on the support plate 11 to achieve the purpose of fixing the second limiting component 31 or the third limiting component 32 to the support plate 11.

[0084] Please refer to the following: Figure 11 and Figure 12 Both the third moving track 111 and the fourth moving track 112 are stepped. Both the third moving track 111 and the fourth moving track 112 include interconnected third channels 1111 and fourth channels 1112. The width of the third channel 1111 is smaller than the width of the fourth channel 1112. The third slider 311 is slidably embedded in the third channel 1111. The third slider 311 can slide along the setting direction of the third channel 1111. The limiting plate 314 abuts against the bottom of the fourth channel 1112, and the third locking fastener 313 abuts against the inner wall of the support plate 11, so that after the position adjustment is completed, the third slider 311 is fixed to the support plate 11 by the clamping force of the third locking fastener 313 and the limiting plate 314.

[0085] As can be seen, the fourth channel 1112 is located outside the third channel 1111. The size and structure of the third slider 311 are adapted to the third channel 1111. The third slider 311 can slide in the third channel 1111. After installation, the third slider 311 can be accommodated in the third channel 1111 and slide along the extension direction of the third channel 1111. The third locking fastener 313 is located above the first slider 212. After the third slider 311 slides to the designated position relative to the third channel 1111, the third locking fastener 313 is tightened by screw thread. In this way, the third locking fastener 313 abuts against the inner wall of the corresponding support plate 11, while the limiting plate 314 abuts against the bottom of the fourth channel 1112. The third locking fastener 313 and the limiting plate 314 use the clamping force on the support plate 11 to achieve the purpose of fixing the third slider 311 to the support plate 11.

[0086] The limiting block 315 is connected and fixed to the third slider 311 by screws. The limiting block 315 is made of hard rubber. Depending on the size of the motherboard, 2 to 4 second limiting components 31 and third limiting components 32 are used to limit the motherboard in the front-back and left-right directions, respectively.

[0087] For example, depending on the size of the motherboard, four second limiting components 31 can be set at the front end of the motherboard, two second limiting components 31 can be set at the rear end, and three third limiting components 32 can be set on each of the left and right sides. In this way, the second limiting components 31 can limit the motherboard in the second direction, and the third limiting components 32 can limit the motherboard in the third direction.

[0088] In some embodiments, a motherboard position detection module and a prompting module may also be provided. The motherboard position detection module may be located on the support plate 11 or side plate 12 inside the frame 10. The motherboard position detection module is used to detect whether the motherboard is placed in place. The motherboard position detection module may be a vision module with a camera or a gravity sensor. After the motherboard is correctly placed in the preset placement position on the support plate 11, the motherboard position detection module is used to send a motherboard placement signal to the prompting module so that the prompting module prompts the on-site operator to perform the motherboard fixing operation.

[0089] Furthermore, a clamping force detection element, such as a stress strain gauge, can be installed on the limiting block 315. When the limiting block 315 clamps the motherboard, the clamping force detection element can detect the clamping force applied by the limiting block 315 to the motherboard. In order to ensure the connection strength between the limiting block 315 and the motherboard, so that the motherboard is not easily detached from the support plate 11 during transportation, the clamping force applied by the limiting block 315 to the motherboard needs to reach a set threshold. Therefore, when the clamping force detected by the clamping force detection element reaches the set threshold, the clamping force detection element sends a signal to the prompting module. After receiving the signal, the prompting module prompts the on-site operator to stop the clamping action.

[0090] This configuration not only ensures the connection strength between the limit block 315 and the motherboard, making it less likely for the motherboard to detach from the support plate 11 during transportation, but also prevents the limit block 315 from applying excessive clamping force to the motherboard, which could damage the motherboard and thus extend its service life.

[0091] In some embodiments, an elastic buffer pad is provided on the sidewall of any limiting block 315. The elastic buffer pad is used to contact and abut against the outer sidewall of the board 50, and the elastic buffer pad is provided with a groove for accommodating the outer sidewall of the board 50. The provision of the elastic buffer pad can protect the board 50 to a certain extent and solve the problem of damage to the board 50 caused by the contact between the limiting block 315 and the board 50.

[0092] In some embodiments, the support and protection device further includes a cover plate 40, which is fixed to the frame 10. The cover plate 40 and the frame 10 together form a sealed cavity, in which the plate 50 is housed.

[0093] The specific process of using the support and protection device provided in the embodiments of the present invention is described in detail below:

[0094] First, based on the motherboard size, whether the motherboard has a heatsink, memory, and other conditions, determine the number of limiting blocks 315, their clamping positions, the number of pressure blocks 231, and the pressing positions of the pressure blocks 231 in the horizontal plane. Each of the four sides of the motherboard requires at least two limiting blocks 315 for limiting, and the upper surface of the motherboard requires at least four pressure blocks 231 of different straight lines for limiting.

[0095] Next, place the motherboard into the frame 10, slide the limit blocks 315 on the four sides to clamp the motherboard horizontally, and lock the third locking fastener 313 corresponding to the limit block 315 after positioning to ensure that the motherboard does not move horizontally.

[0096] Based on the selected number and position of the pressure blocks 231, the first limiting component 23 and the second movable locking component 22 are installed on the appropriate moving rod 211. By sliding the moving rod 211 in the front-back direction and the second slider 222 in the left-right direction, the position of the pressure block 231 in the horizontal plane is adjusted. After the position is set, the corresponding first locking fastener 213 and second locking fastener 223 are locked to ensure that the pressure block 231 does not move in the horizontal plane. The positioning pin 233 corresponding to the pressure block 231 is pulled out, and the pressure block 231 can move up and down to adjust the position of the pressure block 231 to contact the motherboard, heat sink, memory slot, etc. or leave a gap of 1-3mm. Finally, the positioning pin 233 is inserted into the positioning hole 2211 to complete the vertical limiting of the motherboard.

[0097] It is important to emphasize that the motherboard, as the core component of the server, provides crucial support for the server's logical operations, storage, expansion functions, and management. Since the motherboard may be subjected to vibration, drops, and collisions during transportation, it may undergo significant deformation, affecting the reliability of the surface components of the motherboard. Therefore, the protective support for the motherboard during transportation plays an important role in its strength and reliability.

[0098] Therefore, the support and protection device using the above-mentioned configuration integrates horizontal clamping functionality and downward pressing position adjustment functionality, making it suitable for motherboards or PCBs of servers and many electronic products. By moving the first and second limiting modules relative to the moving track on the frame, the motherboard can be fixed in six degrees of freedom (front, back, left, right, up, and down), thus achieving effective support and protection for the motherboard.

[0099] The support and protection device in this embodiment of the invention has strong versatility and adaptability. One set of devices can realize the single-package transportation of motherboards of different sizes, configurations, and functions. The first limiting module 20 and the second limiting module 30 are flexibly adjustable, and the number and position of the pressure block 231 and the limiting block 315 can be selected at will. At the same time, this device is reusable, effectively reducing the packaging and manufacturing cost of the motherboard. In addition, this device can restrict the six degrees of freedom of the board 50, providing strong support and protection, effectively improving the reliability of the support and protection of the motherboard during transportation, and solving the technical problem that the packaging of the board 50 is complex and diverse, and cannot guarantee effective support and protection for the board 50.

[0100] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

Specific examples have been used to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the solution and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the present invention.
