Description

Technical Field

[0001] This utility model relates to the field of metal plate technology, and in particular to a heat dissipation metal plate for electromagnetic interference protection. Background Technology

[0002] Metal plates are an important protective material, commonly used for the external encapsulation of circuit board casings. They are typically made of materials such as aluminum alloy, stainless steel, or galvanized steel, possessing high strength, corrosion resistance, and excellent electromagnetic shielding performance. They can effectively isolate external electromagnetic interference while preventing internal electromagnetic signals from leaking out. Their surfaces are treated with processes such as painting, anodizing, or sandblasting, which not only improves wear and corrosion resistance but also gives them an aesthetically pleasing appearance. Metal plates are usually designed with heat dissipation holes and mounting interfaces to ensure good heat dissipation of the circuit board and facilitate connection with other components. They are widely used in electronic equipment, communication equipment, and computers, providing robust and reliable protection for circuit boards and are key components for ensuring the stable operation of electronic equipment.

[0003] In existing technologies, metal plates are usually used as a whole structure in scenarios such as circuit board housings. This design has certain drawbacks. Since the metal plate cannot be disassembled into individual pieces, once a local damage occurs or the internal circuit board needs to be repaired or upgraded, the entire metal plate often needs to be replaced. This not only increases maintenance costs but also reduces resource utilization. In addition, the weight and volume of the integral metal plate are relatively large, making transportation and installation inconvenient, and it is difficult to adjust flexibly in complex spatial environments. This non-disassembly design limits the use of metal plates in some application scenarios with high requirements for flexibility and maintainability. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-electromagnetic interference heat dissipation metal plate.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an anti-electromagnetic interference heat dissipation metal plate, including a middle metal plate, side metal plates on both sides of the middle metal plate, multiple supporting crossbars detachably connected to the bottom of the middle metal plate, multiple supporting troughs detachably connected to one side of the side metal plates, a placement groove on the top of the supporting trough, a drop groove on the inner wall of the placement groove, two extension grooves on the inner wall of the placement groove, connecting rods fixed at both ends of the supporting crossbars, a connecting rod fixed at one end of the connecting rod, two curved grooves penetrating one side of the rotating disk, cylinders on the inner walls of the two curved grooves, extension blocks fixed on one side of the cylinders, placement blocks on the curved grooves and their surfaces, component grooves and two extension inner grooves on the inner walls of the placement blocks, and the curved grooves sliding on the inner walls of the extension inner grooves.

[0006] Preferably, the top of the intermediate metal plate is provided with heat dissipation fins, the bottom of the heat dissipation fins is fixed with a buckle seat, the top of the intermediate metal plate is provided with a clamping groove, the inner wall of the clamping groove is provided with a clamping slide groove, the inner wall of the clamping groove is provided with two clamping shafts, both ends of the clamping shafts are fixed with sliding blocks, the sliding blocks are slidably connected to the inner wall of the clamping slide groove, both sides of the sliding blocks are fixed with springs, and the other end of the springs is fixed to the inner wall of the clamping slide groove. In existing technologies, heat dissipation fins on metal plates are typically integrated with the substrate. This structure has significant drawbacks. Since the heat dissipation fins are not easily removable, if a fin is damaged or needs replacement, the entire metal plate often must be replaced. This not only increases maintenance costs but also causes unnecessary resource waste. Furthermore, in complex usage scenarios, the non-removable heat dissipation fins limit the flexibility of the metal plate. For example, when cleaning, maintaining, or adapting the metal plate to different heat dissipation requirements, the integrated design causes numerous inconveniences. This design also increases the overall weight and volume of the metal plate, hindering the development of lightweight and compact devices and limiting its use in applications with high requirements for heat dissipation performance and portability. To address these issues, this invention adopts a structure for easy removal of heat dissipation fins. When it is necessary to remove the heat dissipation fins, pull the fins upwards; under the action of force, the latches at the bottom of the heat dissipation fins will engage. The two clamping shafts move to both sides, and simultaneously drive the sliding block to slide along the inner wall of the clamping groove. Under the action of the spring, when the latch seat is freed from the limitation of the two clamping shafts, the two clamping shafts return to their original positions for subsequent installation, achieving multiple positive effects. First, the detachable design allows the heat dissipation fins to be operated independently when damaged or needing replacement, significantly reducing maintenance costs and resource waste. Second, this design improves the flexibility and adaptability of the metal plate, facilitating quick adjustment and optimization according to different heat dissipation needs or usage scenarios. At the same time, the detachable heat dissipation fins help simplify cleaning and maintenance processes and extend the service life of the metal plate. In addition, the split design can reduce the overall weight and volume of the metal plate, making it more suitable for the development of lightweight and compact devices, thereby better meeting the application scenarios with high requirements for heat dissipation performance and portability, and improving the overall performance of the device and user experience.

[0007] Preferably, multiple metal springs are fixed to one side of each of the two side metal plates, and the multiple metal springs are arranged in an array on one side of the side metal plates. In existing technologies, metal plate joints typically lack dedicated electromagnetic interference (EMI) protection measures. This disrupts the continuity of electromagnetic shielding, and the joint gaps become leakage channels for electromagnetic waves, allowing external EMI to enter the metal plate while internal electromagnetic signals leak out. This reduces the overall electromagnetic compatibility (EMC) of the device. This design flaw not only affects the normal operation of electronic equipment but also leads to signal interference and data transmission errors. To address these issues, this invention employs a metal spring structure at the metal plate joints. The array of metal springs forms a dense conductive network that effectively captures and conducts electromagnetic waves, rapidly guiding their energy to the grounding point, thereby reducing the propagation of electromagnetic waves in space. Simultaneously, the elastic properties of the metal springs ensure good contact with the surrounding structure, further enhancing the continuity and stability of the electromagnetic shielding. This structure effectively suppresses the impact of external EMI on internal circuits and prevents internal electromagnetic signal leakage, providing reliable EMC protection for electronic equipment. It is particularly suitable for applications in precision electronic equipment sensitive to EMI and in complex electromagnetic environments.

[0008] Preferably, the engaging portion of the buckle seat has an arc surface, which is smooth. The smooth arc surface design reduces friction during assembly, allowing the buckle to engage or disengage more smoothly from the buckle seat, thereby improving assembly efficiency and convenience. Simultaneously, the smooth arc surface helps reduce wear between the buckle and the buckle seat, extending service life. Furthermore, the arc surface design enhances the stability of the buckle, preventing it from loosening or falling off due to improper assembly or external impact, ensuring the robustness and reliability of structures such as metal plates during use.

[0009] Preferably, the inner walls of the two protruding slots are smooth. This significantly improves the assembly accuracy and performance of the related components. The smooth inner walls reduce friction during assembly, making insertion or sliding operations smoother, reducing assembly difficulty and time costs. Simultaneously, the smooth inner walls effectively reduce wear between components, extending service life. Furthermore, the smooth inner walls improve structural stability, preventing jamming or loosening caused by surface roughness, ensuring good connection performance and reliability during long-term use, thereby improving the overall operating efficiency and stability of the equipment.

[0010] Preferably, thermal grease is applied evenly to the bottom of the heat sink fins. As a highly efficient heat transfer medium, thermal grease can fill the tiny gaps between the heat sink fins and the substrate, eliminating thermal resistance caused by air gaps. This ensures that heat can be quickly and evenly conducted from the substrate to the heat sink fins. This design not only improves heat dissipation efficiency but also effectively reduces the substrate temperature, extends the lifespan of electronic components, and ensures the stability of the device under high load operation.

[0011] Preferably, the surface of the support crossbar is provided with a gripping groove, and the inner wall of the gripping groove is provided with an inclined groove. This can significantly improve the ease of operation and stability during use. The gripping groove provides the user with a clear point of force, making it easy to grip and operate the support crossbar. Especially when a certain amount of force needs to be applied or fine adjustments need to be made, it can provide a better anti-slip effect. The inclined groove further increases the friction and prevents the hand from slipping.

[0012] Beneficial effects:

[0013] 1. In existing technologies, metal plates are typically used as a single unit in applications such as circuit board housings. This design has certain drawbacks. Because the metal plate cannot be disassembled into individual pieces, if partial damage occurs or the internal circuit board needs repair or upgrade, the entire metal plate often needs to be replaced. This not only increases maintenance costs but also reduces resource utilization. Furthermore, the weight and volume of a single metal plate are relatively large, making transportation and installation inconvenient, and it is difficult to adjust flexibly in complex spatial environments. This non-removable design limits the use of metal plates in applications where flexibility and maintainability are critical. To address these issues, this utility model adopts a metal plate disassembly bracket structure. The design significantly enhances the device's performance. First, the detachable design allows for individual replacement of damaged metal plates, drastically reducing maintenance costs and improving resource utilization. Second, the segmented metal plates facilitate individual handling and assembly during transportation and installation, making them particularly suitable for complex spatial environments. This allows for flexible adjustments to the installation method, reducing installation difficulty and time. Furthermore, this design facilitates rapid repair, upgrades, or replacement of internal circuit boards, enhancing maintainability and extending the device's lifespan. This makes it more suitable for applications requiring high flexibility and maintainability, thereby improving overall device performance and user experience. Finally, the cage-like metal plate is a highly efficient electromagnetic shielding structure. By forming a closed or semi-closed metal cage space, it effectively blocks the intrusion of external electromagnetic waves and suppresses the leakage of internal electromagnetic signals through electromagnetic shielding principles.

[0014] 2. In existing technologies, the heat dissipation fins on the metal plate are usually integrated with the substrate. This structure has significant drawbacks. Because the heat dissipation fins cannot be easily disassembled, once the fins are damaged or need replacement, the entire metal plate often must be replaced. This not only increases maintenance costs but also causes unnecessary waste of resources. Furthermore, in complex usage scenarios, the non-removable heat dissipation fins limit the flexibility of the metal plate. For example, when cleaning, maintaining, or adapting the metal plate to different heat dissipation requirements is needed, the integrated design causes many inconveniences. This design also increases the overall weight and volume of the metal plate, which is not conducive to the development of lightweight and compact devices and limits its use in applications with high requirements for heat dissipation performance and portability. The present invention addresses this issue by employing a conveniently detachable heat dissipation fin structure, achieving several positive effects. First, the detachable design allows for individual operation of the heat dissipation fins when damaged or requiring replacement, significantly reducing maintenance costs and minimizing resource waste. Second, this design enhances the flexibility and adaptability of the metal plate, facilitating rapid adjustment and optimization based on different heat dissipation needs or usage scenarios. Furthermore, the detachable heat dissipation fins simplify cleaning and maintenance processes, extending the lifespan of the metal plate. Additionally, the modular design reduces the overall weight and volume of the metal plate, making it more suitable for the development of lightweight and compact devices. This better meets the demands of applications requiring high heat dissipation performance and portability, thereby improving the overall performance of the device and the user experience.

[0015] 3. In existing technologies, metal plate joints typically lack dedicated electromagnetic interference (EMI) protection measures. This disrupts the continuity of electromagnetic shielding, and the joint gaps become leakage channels for electromagnetic waves. External EMI can enter the metal plate through these gaps, while internal electromagnetic signals can also leak out, reducing the overall electromagnetic compatibility (EMC) of the device. This design flaw not only affects the normal operation of electronic equipment but also leads to signal interference and data transmission errors. To address these issues, this invention employs a metal spring structure at the metal plate joints. The array of metal springs forms a dense conductive network that effectively captures and conducts electromagnetic waves, rapidly guiding their energy to the grounding point, thus reducing the propagation of electromagnetic waves in space. Simultaneously, the elastic properties of the metal springs ensure good contact with the surrounding structure, further enhancing the continuity and stability of the electromagnetic shielding. This structure effectively suppresses the impact of external EMI on internal circuits and prevents internal electromagnetic signal leakage, providing reliable EMC protection for electronic equipment. It is particularly suitable for applications in precision electronic equipment sensitive to EMI and in complex electromagnetic environments. Attached Figure Description

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0027] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0029] Reference Figure 1-8The electromagnetic interference-resistant heat dissipation metal plate includes a middle metal plate 1, with side metal plates 101 on both sides of the middle metal plate 1. Multiple support crossbars 102 are detachably connected to the bottom of the middle metal plate 1, and multiple support rails 103 are detachably connected to one side of the side metal plates 101. A placement groove 104 is opened at the top of the support rail 103, and a drop groove 105 is opened on the inner wall of the placement groove 104. Two extension grooves 106 are opened on the inner wall of the placement groove 104. Connecting rods 107 are fixed at both ends of the support crossbars 102, and a connecting rod 107 is fixed at one end. Two curved grooves 109 are opened through one side of the rotating disk 108. A cylinder is provided on the inner wall of the two curved grooves 109, and an extension block 110 is fixed on one side of the cylinder. Placement blocks 111 are provided on the surface of the curved grooves 109 and the surface of the curved grooves 109. A component groove 112 and two extension inner grooves 113 are opened on the inner wall of the placement block 111. The curved groove 109 slides on the inner wall of the extension inner groove 113. In existing technologies, metal plates are typically used as a single unit in applications such as circuit board housings. This design has certain drawbacks. Because the metal plate cannot be disassembled into individual pieces, if partial damage occurs or internal circuit board repairs or upgrades are needed, the entire metal plate often needs to be replaced. This not only increases maintenance costs but also reduces resource utilization. Furthermore, the weight and volume of a single metal plate are significant, making transportation and installation inconvenient, and it is difficult to adjust flexibly in complex spatial environments. This non-removable design limits the use of metal plates in applications where flexibility and maintainability are critical. Therefore, [further details are needed]. To address this issue, this utility model employs a metal plate easy-to-disassemble bracket structure. When the metal plate needs to be disassembled, the support crossbar 102 is rotated. Driven by the support crossbar 102, the connecting rod 107 drives the rotating disk 108 to rotate, causing the two protruding blocks 110 to retract back to the inner wall of the protruding inner groove 113 under the action of the curved groove 109. At this time, the placement block 111 can be removed from the inner wall of the placement groove 104. When installation is required, the placement block 111 is placed on the inner wall of the placement groove 104, and the support crossbar 102 is rotated to make the two protruding blocks 110 extend to the inner wall of the protruding groove 106 for fixation, thus completing the installation.

[0030] The top of the middle metal plate 1 is provided with heat dissipation fins 2, and the bottom of the heat dissipation fins 2 is fixed with a buckle seat 201. The top of the middle metal plate 1 is provided with a clamping groove 202, and the inner wall of the clamping groove 202 is provided with a clamping slide groove 203. The inner wall of the clamping groove 202 is provided with two clamping shafts 204. Both ends of the clamping shafts 204 are fixed with sliding blocks 205. The sliding blocks 205 are slidably connected to the inner wall of the clamping slide groove 203. Both sides of the sliding blocks 205 are fixed with springs 206, and the other end of the springs 206 is fixed to the inner wall of the clamping slide groove 203. In existing technologies, heat dissipation fins on metal plates are typically integrated with the substrate. This structure has significant drawbacks. Because the heat dissipation fins cannot be easily disassembled, once the fins are damaged or need replacement, the entire metal plate often must be replaced. This not only increases maintenance costs but also causes unnecessary waste of resources. Furthermore, in complex usage scenarios, the non-removable heat dissipation fins limit the flexibility of the metal plate. For example, when cleaning, maintaining, or adapting the metal plate to different heat dissipation requirements is needed, the integrated design causes many inconveniences. This design also increases the overall weight and volume of the metal plate, which is not conducive to lightweight and compact devices. The development of heat dissipation fins has limited their use in applications requiring high heat dissipation performance and portability. To address this issue, this invention employs a convenient fin disassembly structure. When the heat dissipation fin 2 needs to be disassembled, it is pulled upwards. Under the action of force, the latch seat 201 at the bottom of the heat dissipation fin 2 will drive the two clamping shafts 204 to move to both sides. At the same time, the two clamping shafts 204 drive the sliding block 205 to slide on the inner wall of the clamping groove 203. Under the action of the spring 206, when the latch seat 201 is freed from the limitation of the two clamping shafts 204, the two clamping shafts 204 return to their original positions for subsequent installation.

[0031] Multiple metal springs are fixed to one side of each of the two side metal plates 101, and the array of multiple metal springs is arranged on one side of the side metal plate 101. In existing technologies, metal plate joints typically lack dedicated electromagnetic interference (EMI) protection measures. This disrupts the continuity of electromagnetic shielding, and the joint gaps become leakage channels for electromagnetic waves, allowing external EMI to enter the metal plate while internal electromagnetic signals leak out. This reduces the overall electromagnetic compatibility (EMC) of the device. This design flaw not only affects the normal operation of electronic equipment but also leads to signal interference and data transmission errors. To address these issues, this invention incorporates a metal spring structure at the metal plate joints. The array of metal springs forms a dense conductive network that effectively captures and conducts electromagnetic waves, rapidly guiding their energy to the grounding point, thus reducing the propagation of electromagnetic waves in space. Simultaneously, the elastic properties of the metal springs ensure good contact with surrounding structures, further enhancing the continuity and stability of electromagnetic shielding. This structure effectively suppresses the impact of external EMI on internal circuits and prevents internal electromagnetic signal leakage, providing reliable EMC protection for electronic equipment. It is particularly suitable for applications in precision electronic equipment sensitive to EMI and in complex electromagnetic environments.

[0032] The snap-fit ​​seat 201 has an arc surface 3 at the engagement point. The arc surface 3 is smooth. The smooth arc surface design reduces the friction of the snap-fit ​​during assembly, allowing the snap-fit ​​to engage or disengage more smoothly, thereby improving assembly efficiency and convenience. At the same time, the smooth arc surface helps reduce wear between the snap-fit ​​and the snap-fit ​​seat, extending service life. In addition, the arc surface design also enhances the stability of the snap-fit, preventing it from loosening or falling off due to improper assembly or external impact, ensuring the firmness and reliability of structures such as metal plates during use. The inner walls of the two protruding slots 106 and the two protruding inner slots 113 are smooth, which can significantly improve the assembly accuracy and performance of related components. The smooth inner walls can reduce the friction of components during assembly, making insertion or sliding operations smoother, reducing assembly difficulty and time costs. At the same time, the smooth inner walls can effectively reduce wear between components, extending service life. In addition, the smooth inner walls can also improve the stability of the structure, preventing jamming or... Loosening ensures good connection performance and reliability during long-term use, thereby improving the overall operating efficiency and stability of the equipment. Thermal grease is applied to the bottom of the heat sink 2. As a highly efficient heat conduction medium, thermal grease can fill the tiny gaps between the heat sink fins and the substrate, eliminating the thermal resistance caused by air gaps. This ensures that heat can be quickly and evenly conducted from the substrate to the heat sink fins. This design not only improves heat dissipation efficiency but also effectively reduces the temperature of the substrate, extends the service life of electronic components, and ensures the stability of the equipment under high load. The support crossbar 102 has a gripping groove 4 on its surface and an inclined groove on its inner wall, which can significantly improve the ease of operation and stability during use. The gripping groove provides the user with a clear point of leverage, making it easy to grip and operate the support crossbar. Especially when a certain force needs to be applied or fine adjustments are made, it can provide a better anti-slip effect. The inclined groove further increases friction and prevents the hand from slipping.

[0033] The working principle of this utility model is as follows: When the metal plate needs to be disassembled, the support crossbar 102 is rotated. Under the drive of the support crossbar 102, the connecting rod 107 drives the rotating disk 108 to rotate, so that under the action of the curved groove 109, the two protruding blocks 110 retract back to the inner wall of the protruding inner groove 113. At this time, the placement block 111 can be removed from the inner wall of the placement groove 104. When installation is required, the placement block 111 is placed on the inner wall of the placement groove 104, and the support crossbar 102 is rotated, causing the two protruding blocks 110 to retract back to the inner wall of the protruding inner groove 113. The heat sink 2 is fixed by extending it to the inner wall of the extension slot 106, and the installation is completed. When it is necessary to remove the heat sink 2, pull the heat sink 2 upward. Under the action of force, the buckle seat 201 at the bottom of the heat sink 2 will drive the two clamping shafts 204 to move to both sides. At the same time, the two clamping shafts 204 drive the sliding block 205 to slide on the inner wall of the clamping slide groove 203. Under the action of the spring 206, when the buckle seat 201 is freed from the limitation of the two clamping shafts 204, the two clamping shafts 204 return to their original position for subsequent installation.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
