[0032] The example embodiments disclosed herein will be described in detail with reference to the drawings, wherein the example embodiments of the present disclosure are shown. It should be understood that the example embodiments of the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the disclosure of the present disclosure can be more thoroughly and completely conveyed to those skilled in the art.

[0033] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be understood as the usual meaning understood by those skilled in the art to which the present application belongs.

[0034] Traditional support structures often focus only on providing basic support functions, such as fixing the mainboard through screws, buckles, etc., without fully considering how to effectively integrate additional components, such as expansion cards, cooling devices, or other peripherals. The limitations of this structure make it necessary to redesign the entire support structure when new functions are needed, or to connect new devices externally, which not only increases manufacturing costs but also leads to increased product size, which is not conducive to the trend of miniaturization and integration.

[0035] In addition, due to the lack of pre-planning for functional expansion in traditional support structures, users may encounter compatibility issues during maintenance or upgrading, limiting the flexibility and scalability of the product. Therefore, there is an urgent need in the market for a new support structure that can not only stably support core components but also conveniently add functional expansion modules.

[0036] To address the above problems, an improved support structure is proposed, which includes a target support member that not only contains a support part for installing a target mainboard but also specially designs a functional expansion part to install target devices that provide expansion functions for the target mainboard. This structure simplifies the installation and maintenance process while improving the versatility and adaptability of the support structure, reducing overall costs and enhancing user experience.

[0037] Reference is made to the accompanying drawings Figure 1 A support structure includes a target support member, which includes a support part 10 and a functional expansion part 20.

[0038] The support part 10 is used to install the target mainboard, and the functional expansion part 20 is used to install the target device, which provides expansion functions for the target mainboard.

[0039] It can be understood that the support structure mainly includes a target support member, which has two key parts: a support part 10 and a functional expansion part 20. The support part 10 is used to install the target mainboard, while the functional expansion part 20 is used to install additional target devices that can provide various expansion functions for the target mainboard, such as increasing computing power, network connectivity, or special interfaces.

[0040] The support part 10 can provide a certain structural strength to stably support the target mainboard. For example, in the case of an ARM mainboard, in order to adapt to the lightness, miniaturization of the case, and the need for users to provide artificial intelligence services, the ARM mainboard is widely used in embedded systems, mobile devices, servers, etc. due to its small size, light weight, low power consumption, and high efficiency. The thin ARM mainboard is attached to the support part 10, which can provide sufficient mechanical strength for the ARM mainboard,

[0041] In addition, the support part 10 can integrate a heat dissipation solution, such as a heat sink or a heat-conducting pad, to help the ARM mainboard maintain an appropriate working temperature. The support part 10 can also be made of a metal material that can conduct heat, which can export the heat of the ARM mainboard through contact. As for the functional expansion part 20, this part allows users to install additional functional modules according to needs, such as Wi-Fi / Bluetooth modules, GPIO expansion boards, M.2 SSD slots, etc., further enhancing the functionality of the ARM mainboard. The design of the functional expansion part 20 fully considers the compatibility with existing interfaces on the ARM mainboard, ensuring the smooth installation and use of the expansion modules.

[0042] By adopting the above support structure, not only the problem of single function of traditional support structure is solved, but also the expansibility and maintenance convenience of the equipment are greatly improved. The structure is suitable for application in high-performance computing platforms and electronic systems that need flexible configuration.

[0043] In some embodiments, reference is made to the accompanying drawings Figure 2 The target support includes a first surface and a second surface arranged opposite to each other, the first surface being used for mounting the target mainboard and the target device, and the second surface being used for contact mounting with the bearing structure; and further comprising:

[0044] An insulating layer 30 is arranged on the first surface and at least corresponds to the support part, so as to insulate the target mainboard from the target support.

[0045] It can be understood that the target support is arranged on two sides and includes a first surface and a second surface arranged opposite to each other. The first surface is the main working surface and is used for mounting the target mainboard and the target device, and the second surface is the mounting surface and is used for contacting and fixing with the bearing structure (such as a case or a frame), so as to ensure the stability and reliability of the whole support structure.

[0046] In order to prevent electrical short circuit or interference, the insulating layer 30 is arranged on the first surface, especially at the position corresponding to the support part 10. The insulating layer 30 ensures the insulating contact between the target mainboard and the support, avoiding short circuit or other electrical faults caused by direct metal contact.

[0047] Among them, the sensitive electronic elements on the mainboard can be protected from electrostatic discharge (ESD) and other potential electrical interference. Through effective isolation, the stability and reliability of the whole system are improved, especially in a high-density wiring environment.

[0048] The insulating layer 30 can be selected from different types of insulating materials, such as polytetrafluoroethylene (PTFE), polyimide (PI), and silica gel. The above-mentioned materials all have excellent electrical insulation performance and temperature resistance, which can ensure their functions under various working conditions, thereby protecting the safe operation of electronic components and improving the stability of the system.

[0049] The installation method is as follows:

[0050] First, lay the insulating layer 30 on the first surface of the target support, ensuring that it completely covers the critical areas that need to be insulated, especially the parts in contact with the mainboard.

[0051] Second, place the mainboard on the first surface where the insulating layer 30 has been laid, ensuring that the mounting hole positions on the mainboard are aligned with the fixing points on the support.

[0052] Then use screws or other fixing methods to fix the mainboard to the support,

[0053] Third, according to the needs, install additional target devices on the functional expansion part 20, such as Wi-Fi modules, GPIO expansion boards, etc. It is necessary to ensure that all the wires are neat and orderly, avoiding crossing or entangling, which will affect subsequent operations.

[0054] Finally, firmly connect the second surface of the support to the bearing structure to ensure the stability and safety of the entire structure.

[0055] Through the above structure, the target mainboard and target device are installed on the support structure, and the target support not only solves the common electrical interference problem in traditional support structures, but also greatly improves the flexibility and maintainability of the equipment.

[0056] In some embodiments, reference is made to the accompanying Figures 1-2 The support part 10 is provided with a first avoiding area 11, which is used to avoid the protruding structure of the target mainboard when the target mainboard is installed on the target support, so that the target mainboard is installed in close contact with the support part 10.

[0057] It can be understood that in order to make the target mainboard and the support fit together, so as to achieve the effect of heat dissipation and support, while avoiding the interference problem caused by the protruding structure on the mainboard, such as processor, chip set or capacitor resistance, etc., the first avoiding area 11 is provided on the support part 10. This area is specially used to avoid the above-mentioned protruding structure, so that the target mainboard can be installed flat on the support, to meet the mechanical stability and electrical performance.

[0058] Among them, the first avoiding area 11 is located on the support part 10, which can be in the form of a groove or a hole, and the size and shape of the first avoiding area 11 are optimized according to the specific parameters (such as height, width, shape, etc.) of the protruding structure, to ensure complete avoidance without affecting the installation of other parts. The first avoiding area 11 is used to ensure that the protruding structure on the mainboard does not come into physical contact with the support part 10, thereby avoiding the potential risk of mechanical stress or damage.

[0059] Therefore, by introducing the first avoiding area 11, the support structure not only solves the installation problem that may be caused by the protruding structure of the mainboard in the traditional design, but also improves the fit between the mainboard and the support part 10, and enhances the mechanical stability and reliability of the whole.

[0060] In some embodiments, reference is made to the accompanying drawings Figures 1-2 The functional expansion part 20 includes a second avoiding area 21 formed on the first surface to form an avoiding space in the functional expansion part 20.

[0061] It can be understood that, in order to further optimize the function and applicability of the target support, the second avoiding area 21 is arranged in the functional expansion part 20. The area is located on the first surface and is intended to provide additional avoiding space for the target devices installed in the functional expansion part 20, to ensure that these devices can coexist harmoniously with the mainboard or other components, avoid physical interference, and guarantee the stability and performance of the whole system.

[0062] Among them, the second avoiding area 21 can be a groove, a hole or a specific geometric shape, so that the target devices installed in the functional expansion part 20 will not be in physical contact with the elements or other structures on the target mainboard, thereby avoiding the potential risk of mechanical stress or damage.

[0063] And the second avoiding area 21 not only avoids the target devices installed in the functional expansion part 20, but also avoids the wiring (such as power lines, data lines, etc.) and the space containing these wiring. It helps to simplify the wiring management, reduce physical interference, and ensure the tidiness and reliability of the system.

[0064] The second avoiding area 21 provides a dedicated space for the wiring, so that the wiring can be arranged neatly without affecting the installation or operation of other components; it also provides additional physical protection by containing the wiring in the avoiding area, reducing the risk of damage to the wiring due to external factors (such as vibration, friction, etc.).

[0065] In some embodiments, reference is made to the accompanying drawings Figures 1-2 The functional expansion part 20 includes a heat dissipation area 22 formed on the first surface for contacting the target devices and transferring the heat of the target devices to the target support.

[0066] It can be understood that, in order to improve the functionality and reliability of the target support, the heat dissipation area 22 is introduced in the functional expansion part 20. The heat dissipation area 22 is located on the first surface and is intended to directly contact the target devices installed in the functional expansion part 20, and effectively transfer the heat generated by these devices to the target support, thereby achieving efficient heat dissipation management. Not only helps to maintain the stable working temperature of the system, but also prolongs the service life of the electronic components.

[0067] The heat dissipation area 22 can be flat or have heat-conducting protrusions, and its size and form are designed according to the specific parameters of the target device (such as the heat generation area, heat source distribution, etc.) to ensure maximum contact area and heat conduction efficiency. The heat dissipation area 22 made of high-thermal-conductivity material can quickly absorb the heat generated by the target device and transfer it to the target support. It can effectively reduce the working temperature of the target device and improve its performance and stability.

[0068] The heat dissipation area 22 can use materials with high thermal conductivity, such as copper, aluminum, or special alloys, to ensure efficient heat conduction. Heat-conducting pads or thermal paste can also be applied between the heat dissipation area 22 and the target device, which can fill small gaps, reduce thermal resistance, and improve heat conduction efficiency.

[0069] In some embodiments, reference is made to the accompanying drawings Figures 1-2 The function expansion part 20 includes a plurality of first limiters 40,

[0070] The first limiters 40 include two ends arranged oppositely, one end is a fixed end for fixed connection with the function expansion part 20, and the other end is a free end which can move relative to the surface of the function expansion part 20;

[0071] The first limiters 40 and the function expansion part 20 form a containing space between the fixed end and the free end, and the movement of the free end relative to the surface of the function expansion part 20 can adjust the size of the containing space.

[0072] It can be understood that in order to optimize the management of the wiring and ensure the cleanliness and reliability of the electronic device, a plurality of first limiters 40 are introduced in the function expansion part 20. The first limiters 40 not only can fix and manage various wires (such as power lines, data lines, etc.), but also can adjust the size of the containing space through the movement of the free end to adapt to different lengths and quantities of wires.

[0073] The fixed end can be integrally formed with the function expansion part 20, can be welded, or can be stably connected through screws and the like to ensure that the limiters do not loosen or shift. The free end can move relative to the surface of the expansion part, allowing users to adjust the position as needed to accommodate different lengths and quantities of wires.

[0074] The free end can make the middle part of the first limiter 40 arch upward by moving closer or farther from the fixed end, thereby forming a containing space between the fixed end and the free end. The containing space not only can be used to fix the wires, but also can protect them from external impact or vibration, enhancing the reliability and durability of the system. The limiters are usually made of high-strength materials (such as stainless steel, aluminum alloy, etc.) to ensure sufficient mechanical strength and durability.

[0075] For example, the first limiting member 40 can be a strip-shaped metal spring that is flexible and can change shape to form a containing space to fix and limit the wiring. By providing a strip-shaped hollow part 60 at the corresponding position of the function expansion part 20, the spring is placed in the hollow part 60, the fixed end is connected with the function expansion part 20, and the free end extends away from the fixed part. The free end adjusts the size of the containing space by moving closer to or further away from the fixed end.

[0076] In some embodiments, reference is made to the accompanying Figures 1-3 The function expansion part 20 includes a second limiting member 50, which is movably installed on the function expansion part 20 to limit the installation of the target device.

[0077] It can be understood that by introducing the second limiting member 50 for limiting the installation of the target device, the support structure not only solves the possible fixing and compatibility problems in traditional design, but also significantly improves the flexibility and reliability of the system. The design flexibility of the limiting member allows it to adapt to different models and specifications of the target device, further improving the universality and market competitiveness of the product.

[0078] Among them, the second limiting member 50 provides a stable fixing point to ensure that the target device does not shift or loosen after installation, enhancing the reliability and durability of the system.

[0079] Users can flexibly adjust the position of the limiting member as needed, simplifying the installation process of the target device and reducing the assembly difficulty. The limiting member not only can be used to fix the target device, but also can protect them from external impact or vibration, enhancing the safety and durability of the system.

[0080] The second limiting member 50 can be a rotating limiting member, connected to the function expansion part 20 through a rotating shaft or hinge, and can rotate around the axis to adapt to different angles and positions.

[0081] The second limiting member 50 can also be a buckle type limiting member, connected to the function expansion part 20 through an elastic buckle, which can be popped out and retracted to facilitate the installation and disassembly of the target device.

[0082] The second limiting member 50 can also be a spring clip type limiting member, which clamps the target device through spring force, and the spring clip can be manually opened or closed.

[0083] The second limiting member 50 can also be a magnetic type limiting member, which uses magnets to attract metal parts on the function expansion part 20 or the target device to achieve fixation. Without screws or other tools, users can directly attract the target device to the right place through magnetic attraction.

[0084] In some embodiments, reference is made to the accompanying Figure 3The second limiting piece 50 comprises a mounting seat 51 and a fixing piece 52.

[0085] The mounting seat 51 is arranged on the function expansion part 20, and a surface of the mounting seat 51 away from the function expansion part 20 is formed with a first end face 511 and a second end face 512 with different heights; the first end face 511 is higher than the second end face 512, and the second end face 512 is arranged around the first end face 511 to form a stepped structure.

[0086] The fixing piece 52 comprises a third end face 521 and an insertion piece 522 vertically arranged on the third end face 521, and a surface area of the third end face 521 is not less than surface areas of the first end face 511 and the second end face 512.

[0087] The first end face 511 is provided with an insertion hole for interference fit with the insertion piece 522, so that the fixing piece 52 is fixedly installed with the mounting seat 51, and the third end face 521 is in contact with the first end face 511, so that the target device is clamped between the second end face 512 and the third end face 521.

[0088] It can be understood that, in order to effectively limit and fix the target device (such as a hard disk, an expansion card, etc.), the second limiting piece 50 is introduced into the function expansion part 20. The second limiting piece 50 is composed of the mounting seat 51 and the fixing piece 52, and through the careful design of the stepped structure and the interference fit, it is ensured that the target device can be stably clamped between the mounting seat 51 and the fixing piece 52, thereby providing reliable fixing effect.

[0089] For example, the target device is an SSD hard disk, which comprises a connecting end and an extending end, the connecting end is connected with a target mainboard, and the extending end extends to a function expansion area, and a circular-arc-shaped recess is arranged on the extending end and is used for assembling the stepped structure of the second limiting piece 50, and the fixing piece 52 is buckled with the mounting seat 51 to realize fixed installation of the extending end.

[0090] The mounting seat 51 can be fixed on the function expansion part 20 by bolts or other mechanical methods, has the first end face 511 and the second end face 512, the first end face 511 is higher than the second end face 512, and is used for abutting contact with the third end face 521 of the fixing piece 52; the second end face 512 is arranged around the first end face 511 and is lower than the first end face 511 to form a stepped structure, the stepped structure forms an assembly space for assembling the target device, and the stepped structure provides an additional support structure for the fixing piece 52 to ensure that the target device is clamped firmly.

[0091] The mounting hole is arranged on the first end face 511 and is used for interference fit with the insertion piece 522 of the fixing piece 52 to ensure the close connection between the fixing piece 52 and the mounting seat 51.

[0092] The fixing member 52 includes a third end face 521, and a surface area of the third end face 521 is not less than a total surface area of the first end face 511 and the second end face 512, so that the third end face 521 can completely cover and fit the first end face 511 and provide sufficient contact area to enhance the fixing effect.

[0093] The insertion member 522 is vertically arranged on the third end face 521 and is inserted into an insertion hole on the mounting seat 51. The size and shape of the insertion member 522 are accurately matched with the insertion hole to achieve an interference fit, which ensures a stable connection between the fixing member 52 and the mounting seat 51 and prevents loosening or displacement.

[0094] In some embodiments, with reference to the accompanying drawings Figure 3 A flexible connecting member 53 is arranged between the mounting seat 51 and the fixing member 52.

[0095] It can be understood that the flexible connecting member 53 is a strip-shaped member, and two ends of the flexible connecting member 53 are respectively used to connect the mounting seat 51 and the fixing member 52 to prevent the fixing member 52 from being lost when separated from the mounting seat 51.

[0096] The flexible connecting member 53 is usually made of a high-elasticity material such as silicone, rubber, or polyurethane, which has good elasticity and durability.

[0097] In some embodiments, with reference to the accompanying drawings Figures 3-4 The second limiting member 50 further includes a rotating member 54, and the rotating member 54 is rotatably arranged on an end of the mounting seat 51 close to the function expansion part 20.

[0098] A first wing plate 513 is arranged on a side wall of the mounting seat 51, and the first wing plate 513 abuts against the function expansion part 20 to fix and support the mounting seat 51.

[0099] A second wing plate 541 is arranged on a side wall of the rotating member 54, and the rotating member 54 rotates relative to the mounting seat 51 to make the second wing plate 541 correspond to or be misaligned with the first wing plate 513.

[0100] A hollow part 60 is arranged at a position corresponding to the mounting seat 51 of the function expansion part 20, and the hollow part 60 is used for the second wing plate 541 to pass through, thereby mounting the second limiting member 50.

[0101] It can be understood that the rotating member 54 is arranged on an end of the mounting seat 51 away from the stepped structure, and can rotate through a bearing or other rotating mechanism. The rotating member 54 can rotate along an axis of the mounting seat 51, thereby realizing dismounting of the second limiting member 50 and the function expansion part 20.

[0102] The first wing plate 513 is arranged on the side wall of the mounting seat 51 and abuts against the function expansion part 20 to fix and support the mounting seat 51. The second wing plate 541 is arranged on the side wall of the rotating part 54, and can correspond to or be misaligned with the first wing plate 513 of the mounting seat 51 along with the rotation of the rotating part 54.

[0103] The function expansion part 20 is provided with a hollow part 60 at a position corresponding to the mounting seat 51, so that the second wing plate 541 passes through the hollow part 60, thereby facilitating the installation and removal of the second limiting part 50.

[0104] The first wing plate 513 and the second wing plate 541 can be oppositely arranged as arc-shaped plates, and each has two fixed support points. The first wing plate 513 abuts against the upper surface of the function expansion part 20 through the two fixed support points, and the second wing plate 541 passes through the hollow part 60 and abuts against the lower surface of the function expansion part 20 through the two fixed support points.

[0105] When the second wing plate 541 corresponds to the first wing plate 513, the second wing plate 541 smoothly passes through the hollow part 60. At this time, the second wing plate 541 is rotated to be misaligned with the first wing plate 513, thereby realizing the installation of the second limiting part 50. The first wing plate 513 and the second wing plate 541 are respectively located on the upper and lower surfaces of the function expansion part 20 and abut against each other to jointly fix and support the mounting seat 51, thereby ensuring that the mounting seat 51 will not be displaced.

[0106] The user can easily remove or adjust the position of the mounting seat 51 by rotating the rotating part 54, thereby simplifying the installation and maintenance process.
