[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0055] See also Figure 1 and Figure 2 The supporting and protecting device provided in the embodiment of the present invention includes a frame 10 , a first limiting module 20 and a second limiting module 30 .

[0056] Please also read Figure 3 The frame 10 is specifically a rectangular frame with an opening at the upper end. The frame 10 includes a support plate 11 and side plates 12 arranged on the left and right sides of the support plate 11. The support plate 11 is used to support the board and the second limit module 30, and the side plates 12 on both sides support the first limit 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 are jointly arranged to form an enclosure structure located at the periphery of the support plate 11. The support plate 11, the two end plates and the two side plates 12 jointly form an inner cavity for accommodating the board 50.

[0057] The first limiting module 20 is movably connected to the side plate 12, and 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. The first direction can be as follows Figure 3 The Z-axis direction shown is also the vertical direction. In this way, the purpose of limiting the board in the vertical direction is achieved through the arbitrary adjustment of the first limiting module 20 in the vertical direction.

[0058] The second limiting module 30 is movably connected to the support plate 11, and is used to clamp the board 50 along the second direction and the 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 is shown, and the third direction can be as follows Figure 3 The Y-axis direction, that is, the second direction and the third direction are two mutually perpendicular directions in the horizontal plane. In this way, the purpose of limiting the board in the horizontal plane is achieved through the arbitrary adjustment of the second limiting module 30 in the horizontal plane.

[0059] It can be seen that during assembly, the board 50 is first placed on the support plate 11 of the frame 10, and then the second limiting module 30 is moved relative to the support plate 11 to clamp the board 50 along the second direction and the third direction respectively, thereby achieving the limitation of the board 50 in a plane perpendicular to the first direction. Afterwards, the first limiting module 20 is moved relative to the side plate 12, and the board 50 is clamped along the first direction by the first limiting module 20, thereby achieving the limitation of the board 50 in the first direction.

[0060] In this way, the board 50 can be fixed and stably supported and protected.

[0061] It should be noted that the board 50 can be a mainboard or a PCB board. Taking the mainboard as an example, the mainboard is the core component of the server and provides important support for the server's logical operations, storage, expansion functions, management, etc. Since the mainboard may vibrate, fall, or collide during transportation, it will cause a large deformation that affects the reliability of the mainboard surface components. Therefore, the protection and support of the mainboard during transportation plays an important role in its strength and reliability. However, the mainboard is currently mainly transported in a single package using a paper box with foam, resulting in a variety of mainboard packaging types and the inability to ensure effective support and protection for the mainboard.

[0062] To this end, the present invention develops an adjustable support and protection device for the single-package transportation of boards 50, which has the functions of arbitrary clamping in the horizontal direction and arbitrary adjustment in the vertical direction, and is suitable for the motherboards or PCB boards of servers and many electronic products. The first limit module 20 and the second limit module 30 of the device are flexible and adjustable. A set of devices can realize the single-package transportation of functional boards 50 of different sizes, and has strong versatility and adaptability. In addition, the device has the characteristics of repeated use, which reduces the packaging production cost. At the same time, the device can limit the six degrees of freedom of the board 50, has strong support and protection, and effectively improves the reliability of the support and protection of the motherboard during transportation, and solves the technical problem that the packaging types of the board 50 are complicated and diverse and cannot guarantee the effective support and protection of the board 50.

[0063] Please also read Figure 4 and Figure 5 The side plate 12 is provided with a first movable track 121, and the first movable track 121 extends along the second direction. The first limiting module 20 is used to move along the first movable 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 also read 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 rail 121, and the first movable locking component 21 is used to move relative to the first movable rail 121 along the second direction, and the first movable locking component 21 is used to be fixed to the first movable rail 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, and the second movable locking component 22 is used to move relative to the first movable locking component 21 along the third direction, and the second movable locking component 22 is used to be 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, and the first limiting component 23 is used to move relative to the second movable locking component 22 along the first direction to abut against the board 50, and the first limiting component 23 is used to be fixed to the second movable locking component 22 after the position adjustment in the first direction is completed.

[0066] It is understandable that the present invention adopts a movable locking system with multi-level moving and fixing functions to limit and fix the board 50. Specifically, as a first-level moving and fixing component, the first moving locking component 21 is movably connected to the first moving rail 121. The connection method of the first moving locking component 21 and the first moving rail 121 can be realized by a slider, a guide rail and other structures, so that the first moving locking component 21 can slide freely on the first moving rail 121, and the moving direction of the first moving locking component 21 is to move relative to the first moving rail 121 along the second direction. When the position of the first moving locking component 21 in the second direction is adjusted, it can be fixed to the first moving rail 121. For example, it can be achieved by a locking screw, a buckle and other fixing devices to ensure that the first moving locking component 21 will not be displaced after being adjusted to a suitable position; the second moving locking component 22 is movably connected to the first moving locking component 21, and the connection relationship between the second moving locking component 22 and the first moving locking component 21 enables the second moving locking component 22 to move on the first moving locking component 21. The moving direction is to move along the third direction relative to the first moving locking component 21. When the position of the second moving locking component 22 in the third direction is adjusted, 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 method of the first limiting component 23 and the second moving locking component 22 enables the first limiting component 23 to be able to adjust its position on the second moving locking component 22. The moving direction of the first limiting component 23 is to move along the 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 to play a limiting role to prevent the board 50 from shaking or position deviation during transportation. When 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 fixation, the first limiting component 23 can stably limit the board 50 to ensure that the board 50 remains in the correct position during subsequent use.

[0067] By adopting the design of the multi-stage movable locking component system, the board card 50 can be accurately positioned and fixed in the first direction according to the position of the board card 50.

[0068] Please also read 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 matched with the first movable track 121, and the first slider 212 can slide relative to the first movable track 121 along the second direction. The movable rod 211 is provided with a second movable track 2111, and the second movable track 2111 extends along the third direction. The first locking member 213 is threadedly connected to the movable rod 211, and the first locking member 213 is used to fix the movable rod 211 to the first movable track 121 after the position of the movable rod 211 is adjusted.

[0069] For example, the first locking piece 213 may be a nut or a hand-tightened stud structure with an internal threaded hole. After the position of the moving rod 211 in the second direction is adjusted, the hand-tightened stud structure can be rotated relative to the moving rod 211 to ensure that the moving rod 211 will not continue to move after being adjusted to a suitable position.

[0070] It can be seen that the first locking piece 213 and the first slider 212 are respectively located on the left and right sides of the first moving rail 121. After the first slider 212 slides to a specified position relative to the first moving rail 121, the first locking piece 213 is tightened by threads. In this way, the first locking piece 213 and the first slider 212 both utilize the clamping force on the first moving rail 121 to achieve the purpose of fixing the moving rod 211 to the first moving rail 121.

[0071] Please also read 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 matched with the second movable track 2111, and the second slider 222 can slide relative to the second movable track 2111 along the third direction. The positioning rod 221 is provided with positioning holes 2211 spaced apart along the first direction; the two second locking members 223 are both threadedly connected with the positioning rod 221, and the two second locking members 223 are respectively located on both sides of the second slider 222 along the first direction. The two second locking members 223 are used to fix the positioning rod 221 to the second movable track 2111 after the position of the positioning rod 221 is adjusted.

[0072] For example, the second locking piece 223 may also be a hand-tightened stud structure with an internal threaded hole. After the position of the positioning rod 221 with the second slider 222 is adjusted in the third direction, the hand-tightened stud structure can be rotated relative to the positioning rod 221 to ensure that the positioning rod 221 will not continue to move after being adjusted to the appropriate position.

[0073] It can be seen that the two second locking pieces 223 are respectively located on the upper and lower sides of the second slider 222. After the second slider 222 slides to the specified position relative to the second movable rail 2111, the second locking piece 223 on the upper side is tightened by threads. In this way, the two second locking pieces 223 utilize the clamping force on the second movable rail 2111 to achieve the purpose of fixing the positioning rod 221 to the second movable rail 2111.

[0074] In some embodiments, the first limiting assembly 23 includes a positioning pin 233 and a pressure block 231 with a sleeve 232, the pressure block 231 is used to abut the board 50, and the sleeve 232 is sleeved on the positioning rod 221; the positioning pin 233 is arranged on the sleeve 232, and the positioning pin 233 is used to embed into the positioning hole 2211 to fix the pressure block 231 to the positioning rod 221.

[0075] The pressing block 231 acts as a positioning member for contacting the board 50. The position of the pressing block 231 can be adjusted arbitrarily along the first direction (i.e., the vertical direction). In this way, the position of the pressing block 231 in the vertical direction can be determined according to the position of the board 50, or the surface device on the board 50. After adjusting the height of the pressing block 231, the positioning pin 233 is embedded in the positioning hole 2211 to fix the pressing block 231 to the positioning rod 221.

[0076] In some embodiments, the positioning pin 233 is an elastic reset pin, which is an integrated structure with the sleeve 232. The elastic reset pin is used to move the pressure block 231 relative to the positioning rod 221 when in the pulled-out state, and to embed into the positioning hole 2211 when in the reset state to fix the pressure block 231 to the positioning rod 221.

[0077] It should be noted that the positioning rod 221 is provided with a plurality of small holes (positioning holes 2211) for matching the positioning pins 233 to realize the positioning of the pressing block 231 in the vertical direction. The positioning pins 233 are elastic reset pins. After the elastic reset pins are pulled out, the pressing block 231 can move up and down. After the hand is released, the elastic reset pins fall into the small holes under the elastic action to realize the up and down positioning of the pressing block 231. The pressing block 231 is a hard rubber structure, which is used to press down the components on the surface of the motherboard, such as PCB, memory slots, radiators, handles, etc. According to the size of the motherboard, 2 to 5 first limit components 23 can be used to limit the motherboard in the vertical direction.

[0078] Of course, according to actual needs, five first movable locking components 21 may be arranged at intervals in the second direction, and at least two second movable locking components 22 and first limit components 23 may be arranged on each first movable locking component 21. For example, three second movable locking components 22 and first limit components 23 may be arranged on one first movable locking component 21, so that three different positions on the mainboard below the first movable locking component 21 may be abutted, and two second movable locking components 22 and first limit components 23 may be arranged on another first movable locking component 21, so that two different positions on the mainboard below the first movable locking component 21 may be abutted.

[0079] Please also read Fig. 9 The first movable track 121 is stepped, and includes a first groove 1211 and a second groove 1212 that are connected to each other. The width of the first groove 1211 is smaller than the width of the second groove 1212. The movable rod 211 is inserted into the first groove 1211, and the first slider 212 is slidably embedded in the second groove 1212.

[0080] It can be seen that the second groove 1212 is located at the outer position of the corresponding first groove 1211, wherein the size and structure of the first slider 212 are adapted to the second groove 1212. After installation, the first slider 212 can be accommodated in the second groove 1212 and slide along the extension direction of the second groove 1212. The first locking piece 213 is located on the inner side of the first slider 212. After the first slider 212 slides to the specified position relative to the second groove 1212, the first locking piece 213 is tightened by threads. In this way, the first locking piece 213 abuts against the inner wall of the corresponding side plate 12. The first locking piece 213 and the first slider 212 both utilize 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 movable rail 111 and a fourth movable rail 112, and the third movable rail 111 and the fourth movable rail 112 extend along the second direction and the third direction respectively; accordingly, the second limiting module 30 includes a second limiting component 31 and a third limiting component 32, and the second limiting component 31 and the third limiting component 32 are slidably matched with the third movable rail 111 and the fourth movable rail 112 respectively.

[0082] Please also read Fig.10The second limiting assembly 31 and the third limiting assembly 32 both include a third slider 311 with a stud 312. The third slider 311 is slidably matched with the support plate 11. The stud 312 is threadedly connected with a third locking piece 313. The third locking piece 313 can also be a hand-tightened stud structure with an internal threaded hole. The diameter of the third locking piece 313 is greater 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 piece 313. The width of the limiting plate 314 is greater than the width of the third slider 311. The third locking piece 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 piece 313 are arranged on the same side of the third slider 311. The limiting block 315 is used to abut against the outer wall of the board 50 to clamp the board 50.

[0083] It can be seen that the third locking piece 313 and the corresponding limiting plate 314 are respectively located on the upper and lower sides of the third slider 311. After the third slider 311 slides to a specified position relative to the support plate 11, the third locking piece 313 is tightened by threads. In this way, the third locking piece 313 and the corresponding limiting plate 314 utilize the clamping force on the support plate 11 to achieve the purpose of fixing the second limiting assembly 31 or the third limiting assembly 32 to the support plate 11.

[0084] Please also read Fig.11 and Fig.12 The third moving track 111 and the fourth moving track 112 are both stepped, and the third moving track 111 and the fourth moving track 112 both include a third groove 1111 and a fourth groove 1112 that are connected to each other. The width of the third groove 1111 is smaller than the width of the fourth groove 1112. The third slider 311 can be slidably embedded in the third groove 1111. The third slider 311 can slide along the setting direction of the third groove 1111. The limiting plate 314 is against the bottom of the fourth groove 1112, and the third locking piece 313 is against the inner wall of the support plate 11, so that the third slider 311 is fixed to the support plate 11 by the clamping force of the third locking piece 313 and the limiting plate 314 after the position adjustment is completed.

[0085] The third locking member 313 is disposed on the upper side of the first slide block 212 and the lower side of the first slide block 314 is connected to the locking member 316 via the locking mechanism 318. The third locking member 313 is connected to the locking member 316 via the locking mechanism 318.

[0086] The limit block 315 is connected and fixed to the third slider 311 by screw connection, and the material of the limit block 315 is hard rubber. According to the size of the mainboard, 2 to 4 second limit assemblies 31 and third limit assemblies 32 are used in the front and rear directions and the left and right directions to limit the mainboard in the front and rear directions.

[0087] For example, according to the size of the mainboard, four second limiting components 31 can be set at the front end of the mainboard, 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 are used to limit the mainboard in the second direction, and the third limiting components 32 are used to limit the mainboard in the third direction.

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

[0089] Furthermore, a clamping force detection device, such as a stress strain gauge, can be provided on the limit block 315. When the limit block 315 clamps the mainboard, the clamping force detection device can detect the clamping force applied by the limit block 315 to the mainboard. In order to ensure the connection strength between the limit block 315 and the mainboard and prevent the mainboard from being easily separated from the support plate 11 during transportation, it is necessary to make the clamping force applied by the limit block 315 to the mainboard reach a set threshold. Therefore, when the clamping force detected by the clamping force detection device reaches the set threshold, the clamping force detection device feeds back a signal to the prompt module. After receiving the signal, the prompt module prompts the on-site operator to stop the clamping action.

[0090] Such a setting method can not only ensure the connection strength between the limit block 315 and the mainboard, so that the mainboard is not easily separated from the support plate 11 during transportation, but also prevent the limit block 315 from applying excessive clamping force on the mainboard and causing damage to the mainboard, which is beneficial to improving the service life of the mainboard.

[0091] In some embodiments, an elastic buffer pad is provided on the side wall of any limit block 315, and the elastic buffer pad is used to contact and abut against the outer side wall of the board 50, and the elastic buffer pad is provided with a groove, and the groove is used to accommodate the outer side wall 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 damaging the board 50 due to the contact between the limit block 315 and the board 50.

[0092] In some embodiments, the supporting and protecting device further includes a cover plate 40 , which is fixed on the frame 10 . The cover plate 40 and the frame 10 together form a sealed cavity, so that the board 50 is accommodated in the sealed cavity.

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

[0094] First, according to the size of the motherboard, whether the motherboard has a heat sink, memory and other conditions, determine the number of limit blocks 315 in the horizontal plane, the clamping position, the number of pressure blocks 231, and the downward pressing position of the pressure blocks 231. Each of the four sides of the motherboard requires at least two limit blocks 315 for positioning, and the upper surface of the motherboard requires at least four different straight lines of pressure blocks 231 for positioning.

[0095] Afterwards, put the mainboard into the frame 10, slide the limit blocks 315 on the four sides, clamp the mainboard horizontally, and after positioning, lock the third locking piece 313 corresponding to the limit blocks 315 to ensure that the mainboard does not move in the horizontal direction.

[0096] According to the number and position of the selected pressing blocks 231, the first limiting component 23 and the second movable locking component 22 are installed on a suitable moving rod 211. The position of the pressing block 231 in the horizontal plane is adjusted by sliding the moving rod 211 in the front-to-back direction and the second sliding block 222 in the left-to-right direction. After the position is determined, the corresponding first locking piece 213 and the second locking piece 223 are locked to ensure that the pressing block 231 does not move in the horizontal plane; the positioning pin 233 corresponding to the pressing block 231 is pulled out, and the pressing block 231 can move up and down. The position of the pressing block 231 is adjusted to contact with the mainboard, radiator, memory slot and other positions or leave a 1-3mm gap. Finally, the positioning pin 233 is inserted into the positioning hole 2211 to complete the limitation of the mainboard in the vertical direction.

[0097] It should be emphasized that the motherboard, as the core component of the server, provides important support for the server's logical operations, storage, expansion functions, management, etc. Since the motherboard may vibrate, fall, or collide during transportation, it will cause significant deformation and affect the reliability of the motherboard's surface devices. Therefore, the protection and support of the motherboard during transportation plays an important role in its strength and reliability.

[0098] Therefore, the support and protection device adopting the above-mentioned setting method integrates the functions of arbitrary clamping in the horizontal direction and arbitrary adjustment of the downward pressing position, and is suitable for the motherboards or PCB boards of servers and many electronic products. By moving the first limit module and the second limit module relative to the moving track on the frame, the six degrees of freedom of the front, back, left, right, up and down of the motherboard can be limited and fixed, thereby achieving the purpose of effectively supporting and protecting the motherboard.

[0099] The supporting and protecting device in the embodiment of the present invention has strong versatility and adaptability. A set of devices can realize the single-package transportation of motherboards of different sizes, different configurations, and different functions. The first limiting module 20 and the second limiting module 30 are flexible and adjustable, and the number and position of the pressing block 231 and the limiting block 315 can be selected at will. At the same time, the device has the characteristics of repeated use, which effectively reduces the packaging and production cost of the motherboard. In addition, the device can limit the six degrees of freedom of the board 50, has strong supporting and protective properties, and effectively improves the reliability of supporting and protecting the motherboard during transportation, solving the technical problem that the packaging types of the board 50 are complicated and diverse and cannot guarantee the effective support and protection of the board 50.

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

The description of the above embodiments is only used to help understand the scheme of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the present invention.
