Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to an electromagnetic noise shielding structure for UAVs. Background Technology

[0002] For drones to achieve precise and stable flight, they primarily rely on onboard sensors to monitor their status in real time, feeding this information back to the flight control system. The flight control system then processes the data and outputs corresponding control signals. Because the drone's onboard and ground terminals need to transmit data, images, and control signals in real time, and because drones operate with high and rapidly changing current, complex electromagnetic interference arises between the aircraft's onboard equipment. Furthermore, drones may encounter complex electromagnetic interference environments during operation. This interference can affect the aircraft's sensors and onboard equipment, causing deviations or errors in the reported aircraft status, and in severe cases, directly leading to sensor or equipment malfunction. Therefore, electromagnetic shielding design is necessary for drones to improve their electromagnetic shielding effectiveness and minimize the impact of the electromagnetic environment on sensors and onboard equipment.

[0003] Currently, carbon fiber is used as the outer shell of the drone's loading box to shield the drone from electromagnetic noise. Although carbon fiber can be used as a shielding material, it is expensive, easily worn, and difficult to repair. Carbon fiber is also relatively brittle, with high axial stress but poor radial stress, and it is easy to break when bent. Therefore, an electromagnetic noise shielding structure for drones is needed to improve the above problems. Utility Model Content

[0004] To address the current practice of using carbon fiber as the outer shell of a drone's loading box for electromagnetic noise shielding, which utilizes carbon fiber for shielding, the present invention aims to provide an electromagnetic noise shielding structure for drones to solve the problems mentioned in the background art. This structure addresses the issues of high cost, easy wear and repair, brittle texture, high axial stress but poor radial stress, and easy breakage upon bending.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, when the electromagnetic wave reflection rod is used for reflection loss, the shielding material has charge carriers that can move freely in the magnetic field and needs to have good conductivity. When absorption attenuation is used, the shielding material has a large number of electric or magnetic dipoles and needs to have high electromagnetic loss, high permeability and suitable dielectric constant. When multiple reflection attenuation is used, the porous structure in the shielding material can greatly increase the number of multiple reflections and multiple scatterings, thereby effectively improving the shielding performance.

[0025] Example: Please refer to Figures 1-4 The electromagnetic noise shielding structure of a drone shown includes a main body 1, a control component 2 fixedly connected inside the main body 1, and a support component 3 fixedly connected to the bottom of the main body 1.

[0026] In this embodiment, reference is made to Figure 1 , Figure 2 and Figure 4As shown, the main body 1 includes an electromagnetic shielding box 101, with a reflective electromagnetic wave rod 104 fixedly connected to the top of the electromagnetic shielding box 101. The control component 2 includes a mounting plate 201, with a power supply 202, an electronic speed control unit 203, a balance control module 204, a ground-following radar unit 205, a GPS positioning module 206, an intelligent obstacle avoidance module 207, a flight control module 208, and a super-large capacitor 209 fixedly connected to the side of the mounting plate 201. When the reflective electromagnetic wave rod 104 is used for reflection loss, the shielding material has charge carriers that can move freely in the magnetic field and needs to have good conductivity. When it is used for absorption attenuation, the shielding material has a large number of electric or magnetic dipoles and needs to have high electromagnetic loss, high permeability, and a suitable dielectric constant. When it is used for multiple reflection attenuation, the porous structure in the shielding material can greatly increase the number of multiple reflections and multiple scatterings, thereby effectively improving the shielding performance.

[0027] The electromagnetic shielding box 101 has an antenna 102 fixedly connected to its top, a probe 103 fixedly connected to the top of the antenna 102, an L-shaped rod 105 fixedly connected to the side of the electromagnetic shielding box 101, a driver 106 mounted on the top of the L-shaped rod 105, a rotor 107 fixedly connected to the output end of the driver 106, and a top cap 108 on the top of the rotor 107. There are four components: L-shaped rod 105, driver 106, rotor 107, and top cap 108. The system also includes a power supply 202, an electronic speed control unit 203, a balance control module 204, a ground-following radar unit 205, and a G-band radar. The PS positioning module 206, intelligent obstacle avoidance module 207, flight control module 208, and super-large capacitor 209 are all electrically connected. The mounting plate 201 has four mounting holes 210 inside. The electromagnetic shielding shell outside the electromagnetic shielding box 101 further reduces the impact of external electromagnetic interference on the internal circuit. The intelligent obstacle avoidance module 207 improves sensor technology, enhances the UAV's perception capabilities in various environments, and optimizes the multi-sensor data fusion algorithm, enabling mutual backup and supplementation between sensors, thereby improving the overall perception performance and safety of the UAV.

[0028] In this embodiment, reference is made to Figure 1 and Figure 3 As shown, the support assembly 3 includes support rods 301, and four support rods 301 are provided. Two skid-type landing gears 302 are fixedly connected to the bottom of the support rods 301.

[0029] In this solution, an electromagnetic noise shielding structure for a drone is used. When the drone is affected by electromagnetic noise, the electromagnetic wave reflector 104 reflects and attenuates the electromagnetic interference signal. The shielding material inside the electromagnetic wave reflector 104 has charge carriers that can move freely in a magnetic field and needs to have good conductivity. When absorption and attenuation are performed, the shielding material has a large number of electric or magnetic dipoles and needs to have high electromagnetic loss, high permeability, and a suitable dielectric constant. When multiple reflection attenuation is performed, the porous structure in the shielding material can greatly increase the number of multiple reflections and multiple scatterings, thereby effectively improving the shielding performance. The GPS positioning module 206 can accurately locate the drone's position, and the intelligent obstacle avoidance module 207 improves the drone's perception ability in various environments and enhances the drone's flight safety.
