Description

Technical Field

[0001] This utility model relates to the field of AI hardware modules, and in particular to an anti-interference signal shielding box for AI hardware modules. Background Technology

[0002] AI hardware modules are compact functional units that integrate AI processing cores, sensor interfaces, and communication modules. They are widely used in industrial testing equipment and other scenarios, but they are susceptible to external interference during operation and require shielding boxes for protection.

[0003] Existing shielding boxes require heat dissipation holes to solve the heat dissipation problem of AI hardware modules. However, the heat dissipation holes of the shielding box destroy the integrity of the metal shielding, which will form an electromagnetic wave channel and directly lead to the amplification of external interference signals, which will affect the normal operation of the AI ​​hardware module. To address this issue, we propose an anti-interference signal shielding box for AI hardware modules. Utility Model Content

[0008] In a further embodiment, the bottom surface of the shielding outer box is provided with an air inlet hole, and the inner wall of the air inlet hole is threaded with an air inlet metal mesh plate.

[0009] In a further embodiment, the outer surface of the shielding inner box has two side ventilation holes, and the inner wall of the shielding outer box is fixedly connected to two partitions. The sides of the two partitions that are close to each other are fixedly connected to the outer surface of the shielding inner box, and the two partitions are respectively located below the two heat dissipation holes.

[0010] In a further embodiment, two sets of mounting components are fixedly connected to the outer surface of the shielding outer box, and mounting holes are provided on one side of each set of mounting components.

[0011] In a further embodiment, two sets of wiring sockets are fixedly embedded on the outer surface of the shielding outer box, and two sets of wire through holes are opened on the inner wall of the shielding inner box.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This device utilizes a double-layer metal shielding structure formed by an outer and inner shielding box. Leveraging the strong reflective properties of metal, it enhances the ability to block external interference signals. Additionally, the lower ferrite sheet and two side ferrite sheets absorb residual electromagnetic waves penetrating the heat dissipation holes and air inlets, converting electromagnetic wave energy through magnetic loss. Furthermore, the heat dissipation metal mesh and air inlet metal mesh further reduce electromagnetic interference, effectively blocking electromagnetic wave channels and ensuring the AI ​​hardware module board is protected from external interference.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5In this utility model, the AI ​​hardware module anti-interference signal shielding box includes an outer shielding box 1, a shielding door 2 hinged to one side of the outer shielding box 1 via a pin, an inner shielding box 3 fixedly connected to the inner wall of the outer shielding box 1, an AI hardware module board 4 fixedly installed on the inner wall of the inner shielding box 3, a lower ferrite sheet 5 fixedly connected to the bottom surface of the inner shielding box 3, two side ferrite sheets 6 fixedly connected to the outer surface of the inner shielding box 3, a first shielding pad 19 fixedly connected to one side of the shielding door 2, and a second shielding pad 13 fixedly connected to the inner wall of the outer shielding box 1. Made of high-conductivity brass or tin-plated steel, the shielding mechanism utilizes the electromagnetic wave reflection and absorption properties of metal to block external interference signals outside the enclosure and prevent internal electromagnetic wave leakage, providing the first line of shielding for internal components. The shielding door 2 is made of the same material as the outer shielding box 1 and is hinged to it via a pin for opening and closing. When closed, it fits tightly against the outer shielding box 1, forming a complete enclosed shielding space, ensuring that electromagnetic waves cannot penetrate through the door gaps and guaranteeing the integrity of the overall shielding. The inner shielding box 3 is made of aluminum alloy, which is lightweight and... With excellent shielding performance, it is nested inside the outer shielding box 1. The double-box structure enhances the attenuation of electromagnetic waves and effectively blocks residual interference signals that penetrate the outer shielding box 1, providing a more reliable shielding environment for the AI ​​hardware module board 4. The core components of the AI ​​hardware module board 4 are soldered onto an epoxy resin fiberglass substrate and fixed to the inner wall of the inner shielding box 3. The insulation properties of the substrate prevent conductive interference between the components and the metal box. At the same time, with the double shielding of the inner and outer boxes, the interference of external signals on the circuits on the module board is reduced, ensuring its stable operation. The first shielding pad 1 The first shielding pad 19 and the second shielding pad 13, made of conductive foam or beryllium copper spring sheet, are fixed to the side of the shielding door 2 and the inner wall of the shielding outer box 1, respectively. The continuity of the conductive material eliminates the electromagnetic wave leakage path at the gaps, enhancing the overall shielding effect. The shielding outer box 1 and the shielding inner box 3 form a double-layer metal shield, which uses the metal reflection characteristics to block external electromagnetic waves. The lower ferrite sheet 5 and the two side ferrite sheets 6 absorb the remaining electromagnetic waves that have penetrated, and weaken the interference through magnetic loss. The first shielding pad 19 of the shielding door 2 and the second shielding pad 13 on the inner wall of the shielding outer box 1 enhance the anti-interference effect.

[0021] In a further embodiment, the upper surface of the inner shielding box 3 is provided with heat dissipation holes 12, and the inner top wall of the outer shielding box 1 is fixedly connected with a flow guide block 14, which is located above the heat dissipation holes 12. The outer surface of the outer shielding box 1 is provided with two heat dissipation through holes 7, and the inner walls of the two heat dissipation through holes 7 are fixedly connected with heat dissipation metal mesh plates 8. The bottom surface of the outer shielding box 1 is provided with an air inlet hole 9, and the inner wall of the air inlet hole 9 is threadedly connected with an air inlet metal mesh plate 10. The outer surface of the inner shielding box 3 is provided with two side ventilation holes 11, and the inner wall of the outer shielding box 1 is fixedly connected with two partitions 20. The two sides of the shielded inner box 3 are fixedly connected to the outer surface of the shielded inner box 3. The two partitions 20 are located below the two heat dissipation holes 7. The heat dissipation holes 12 cooperate with the flow guide block 14 on the inner top wall of the shielded outer box 1 to guide the heat out in a directional manner. The two heat dissipation holes 7 and the internal heat dissipation metal mesh plate 8 can block electromagnetic waves by using the cut-off waveguide effect while dissipating heat. The air inlet metal mesh plate 10 of the air inlet hole 9 filters the air and blocks electromagnetic waves, which can replenish the internal cold air. The side ventilation hole 11 of the shielded inner box 3 cooperates with the two partitions 20 to enable the airflow to flow through the module in an orderly manner and improve the heat dissipation efficiency.

[0022] In a further embodiment, two sets of mounting parts 15 are fixedly connected to the outer surface of the shielding outer box 1. Each set of mounting parts 15 has a mounting hole 16 on one side. Two sets of wiring sockets 17 are fixedly embedded on the outer surface of the shielding outer box 1. Two sets of wire holes 18 are provided on the inner wall of the shielding inner box 3. The two sets of mounting parts 15 and mounting holes 16 make it easy to fix the shielding outer box 1 in the required position and ensure installation stability. The cooperation between the two sets of wiring sockets 17 and the wire holes 18 inside the shielding inner box 3 facilitates the connection of external lines to the AI ​​hardware module board 4.

[0023] The working principle of this utility model is as follows: First, the outer shielding box 1 and the inner shielding box 3 form a double-layer metal shielding structure, which uses the reflection characteristics of metal on electromagnetic waves to block external interference. Then, the lower ferrite sheet 5 and the two side ferrite sheets 6 can absorb electromagnetic waves that penetrate the heat dissipation holes 7 and the air inlet holes 9. The electromagnetic wave energy is converted into heat energy through the magnetic loss of the ferrite, which further weakens the influence of interference signals on the AI ​​hardware module board 4. When dissipating heat, the heat dissipation holes 12, the two heat dissipation holes 7 and the air inlet holes 9 form a heat dissipation channel. Through the heat dissipation metal mesh plate 8 in the heat dissipation holes 7 and the air inlet metal mesh plate 10 in the air inlet holes 9, the cutoff waveguide effect of the metal mesh is used to block high-frequency electromagnetic waves while allowing airflow. This can ensure the heat dissipation of the AI ​​hardware module board 4 and reduce the influence of electromagnetic wave channels caused by heat dissipation through multiple structures.
