Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless network relay expansion devices, in particular to an anti-interference and high-stability wireless network relay expansion device. BACKGROUND

[0002] With the rapid development of wireless communication technology, wireless relay devices play an increasingly important role in expanding network coverage and enhancing signal stability. However, in actual applications, especially in industrial environments, dense urban areas or complex electromagnetic scenarios, existing wireless relay devices still have many technical bottlenecks, which seriously affect communication quality and system reliability.

[0003] First of all, in a complex electromagnetic environment, traditional relay devices usually use simple metal shells or plastic shells, which have limited electromagnetic shielding effectiveness. For example, although ordinary aluminum alloy shells have some shielding effect, they have poor shielding effect for high-frequency signals such as 5GHz Wi-Fi or millimeter wave communication. In addition, the antennas of existing devices are mostly fixed in design and cannot be dynamically adjusted according to real-time signal quality, resulting in a significant decline in communication quality when the interference source changes (such as the addition of new wireless devices or the start and stop of industrial motors). Some improved solutions try to use directional antennas or external filters, but this increases system complexity and cost and cannot achieve adaptive anti-interference.

[0004] Secondly, the shell structure of existing relay devices usually adopts screw fixation or buckle design, which is inconvenient to disassemble and assemble, and is prone to loose connection due to vibration after long-term use.

[0050] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0051] Embodiment 1

[0052] Please refer to Figures 1-6 A kind of anti-interference, high stability wireless network relay extension device, including device shell 100, wireless relay module 200 and antenna module 300, wherein, device shell 100 includes main shell 101, closure cover 102, mounting table 103 and locking component 400, i.e., mounting port 104 is arranged on one side of main shell 101, and mounting table 103 is slidably connected in main shell 101 by mounting port 104, specifically, guide rail 105 is fixedly connected on the inner wall of main shell 101, rail slot 106 is arranged on mounting table 103, and guide rail is slidably connected in rail slot 106;

[0054] The mounting table 103 is further fixedly connected with a closing cover 102. When the mounting table 103 is located inside the main shell 101, the closing cover 102 closes the mounting opening 104, and a locking component 400 is arranged on the closing cover 102, so that the closing cover 102 is connected with the main shell 101 through the locking component 400;

[0055] In the embodiment, the main shell 101 comprises a shell layer 1011, a middle shell layer 1012 and an inner shell layer 1013. The shell layer 1011 is provided with a honeycomb hole 1014, the shell layer 1011 is fixedly connected with the middle shell layer 1012, and the inner wall of the middle shell layer 1012 is fixedly connected with the inner shell layer 1013.

The outer layer 1021 is made of anodized aluminum material, the middle layer 1022 is made of copper, and the inner layer 1023 is a carbon nanotube coating.

[0057] In the above structure, the aluminum oxide is an insulating material, which can preliminarily shield electric field and low-frequency electromagnetic waves. Through the honeycomb structure, high-frequency electromagnetic waves can be attenuated by multiple reflections (similar to the waveguide filtering principle), and especially the interference of the microwave frequency band can be inhibited to a certain extent. The honeycomb structure enhances the mechanical strength and can disperse thermal stress to avoid thermal noise interference to the internal circuit.

The sealed design further prevents electromagnetic leakage and provides complete Faraday cage effect.

[0059] In addition, the copper shell is provided with a grounding column, which is grounded through a wire. Through grounding, static electricity and external induced current can be led away, thereby significantly reducing electrostatic discharge (ESD) and common mode interference.

[0060] Furthermore, the carbon nanotube has high electrical conductivity and dielectric loss, which can absorb residual high-frequency electromagnetic waves, make up for the deficiency of the copper shell in the high-frequency band, and the coating can inhibit the electromagnetic radiation (such as digital signal harmonics) generated by the internal circuit to avoid self-interference.
