[0001] The present invention relates to the field of unmanned aerial vehicle (UAV) shielding covers and discloses a UAV shielding cover based on a low-density aluminum alloy and a preparation method thereof. Background Art

[0002] A drone shield is a component installed on a drone to protect the drone's internal electronic equipment from external electromagnetic interference. It ensures that the drone's flight control system, navigation system, communication module and other electronic equipment can operate stably and reliably in a complex electromagnetic environment, ensuring that the drone's flight attitude control, positioning accuracy, data transmission and other functions are not affected, thereby improving the drone's anti-interference ability and working stability.

[0003] The widespread application of drones in various fields, such as aerial photography, logistics distribution, and agricultural plant protection, has led to higher demands for their endurance and operational flexibility. Drone batteries have limited capacity, so reducing the weight of the drone can effectively reduce energy consumption and increase flight time. As a component of a drone, reducing the weight of its shield is crucial to improving its overall performance. Therefore, a drone shield based on a low-density aluminum alloy was proposed.

[0004] However, when the UAV is operating, most of the traditional shielding covers will vibrate due to the vibrations generated by the internal parts, causing the shielding covers to resonate, thereby reducing the shielding effectiveness. Summary of the Invention

[0021] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0022] Please see the attached Figure 1 -Attached Figure 5 An embodiment of the present invention provides a drone shielding cover based on low-density aluminum alloy, comprising a lower shell 1, the inner wall of the lower shell 1 being slidably connected to a shielding cover body 2, the outer wall of the shielding cover body 2 being fixedly connected to a rotating bracket 1 3, the outer wall of the rotating bracket 1 3 being fixedly connected to a connecting rod 4, the outer wall of the connecting rod 4 being fixedly connected to a rotating bracket 2 5, the outer wall of the rotating bracket 2 5 being fixedly connected to a slider 6, both sides of the outer wall of the slider 6 being fixedly connected to a limiting block 7, the outer wall of the slider 6 being fixedly connected to a spring 8, a sliding groove 9 being provided on the inner wall of the lower shell 1, a limiting groove 2 11 being provided on the inner wall of the lower shell 1, both sides of the outer wall of the shielding cover body 2 being fixedly connected to a limiting plate 12, and an airborne device 13 being provided in the middle of the upper surface of the lower shell 1.

[0023] Specifically, the UAV is subjected to its own vibration during flight, which causes the shielding cover body 2 to be pressed down. The downward pressure of the shielding cover body 2 drives the rotating bracket 3 to move, and then drives the rotating bracket 3 to move. Since the other end of the connecting rod 4 is fixed by the rotating bracket 2 5 and the slider 6, the connecting rod 4 pushes the rotating bracket 2 5 to move, thereby driving the slider 6 to slide on the inner wall of the slide groove 9, and at the same time drives the limit block 7 to move on the inner wall of the limit groove 10, and compresses the spring 8. When the lower shell 1 moves downward, it simultaneously drives the limit plate 12 to move on the inner wall of the limit groove 2 11, thereby absorbing the vibration energy during the flight of the UAV and avoiding the reduction of shielding efficiency due to resonance.

[0024] Please see the attached Figure 2 -Attached Figure 5 The outer wall of the slider 6 is slidably connected to the inner wall of the slide groove 9, the outer wall of the limit block 7 is slidably connected to the inner wall of the limit groove 10, and the outer wall of the spring 8 is fixedly connected to the inner wall of the slide groove 9.

[0025] Specifically, the slider 6 slides on the inner wall of the slide groove 9, and the limit block 7 slides on the inner wall of the limit groove 10. The movement directions of the slider 6 and the limit block 7 are certain, which prevents the movement trajectories of the slider 6 and the limit block 7 from changing and causing the overall structure to be stuck. The two ends of the spring 8 are respectively connected to the inner wall of the slide groove 9 and the outer wall of the slider 6, so that the downward pressure of the shielding cover body 2 is absorbed by the spring 8 to produce a deformation effect.

[0026] Please see the attached Figure 2,The airborne equipment 13 includes processing sensor data, controlling motors and steering gears, data ,radio, Wi-Fi module, battery management system, memory chip, and SD card.

[0027] Specifically, by processing sensor data, controlling the coordination of motors and servos, digital radios, Wi-Fi modules, battery management systems, memory chips, and SD cards, intelligent flight control and stability are achieved.

[0028] Please see the attached Figure 3 -Attached Figure 5 The outer wall of the limiting plate 12 is slidably connected to the inner wall of the limiting groove 11, and the displacement distance of the limiting plate 12 is equal to the moving distance of the slider 6.

[0029] Specifically, the limiting plate 12 is slidably connected to the inner wall of the limiting groove 11, so that the shielding cover body 2 can ensure that the airborne equipment 13 is fully protected, preventing the vibration from rising too high, exposing the airborne equipment 13, and causing interference to the parts inside the airborne equipment 13.

[0030] Please see the attached Figure 6 A method for preparing a shield cover for a drone based on a low-density aluminum alloy, for a shield cover for a drone based on a low-density aluminum alloy according to any one of claims 1 to 4, the method comprising the following steps: S1. Prepare raw materials: select AL50 aluminum alloy plate as raw material; S2. Stamping: The AL50 aluminum alloy sheet is formed into a preliminary outline through a stamping process; S3, Laser cutting: Use laser cutting equipment to perform precision processing on the AL50 aluminum alloy sheet with preliminary outline; S4. Quality inspection: Perform quality inspection on the precision-formed AL50 aluminum alloy plates; S5. Surface treatment: Anodize the surface of the finished product.

[0031] Specifically, in step S1, AL50 aluminum alloy is used to replace traditional nickel silver to make key hardware components, which reduces weight by ≤70% compared to traditional nickel silver. In step S2, the selected AL50 aluminum alloy material is preliminarily formed by a stamping process; In step S3, the initially formed AL50 aluminum alloy material is precisely processed by laser equipment to ensure that the AL50 aluminum alloy material meets the installation specifications of the drone while maintaining excellent patch performance; In step S4, the completely formed AL50 aluminum alloy material is tested to ensure that the formed AL50 aluminum alloy material meets the requirements of flatness ≤ 0.06 mm and tensile strength ≥ 300 MPa; In step S5, the surface of the finished product that has passed the inspection is treated to form an oxide layer.

[0032] The composition of the AL50 aluminum alloy in S1 is: Al content ≥90wt%, Si 0.5-1.5%, Mg 0.8-1.2%, and the balance is Fe, Cu and unavoidable impurities, and the total amount of impurities is ≤0.3%.

[0033] Specifically, the AL50 aluminum alloy cover made of the above materials can increase the elongation of hardware by 15%, achieve flatness ≤ 0.06mm, and tensile strength ≥ 300MPa, achieving the weight reduction requirements of unmanned aerial vehicle materials, greatly extending the flight time of the drone and enhancing the overall performance.

[0034] The S2 stamping process uses a multi-station progressive die and performs step-by-step stamping at a pressure of 200-300 MPa. During the stamping process, the die temperature is controlled at 80-120°C and the sheet temperature is maintained at 25±5°C.

[0035] Specifically, the AL50 aluminum alloy material is processed and formed by integrating punching, bending, stretching, and precision pressing into a single mold, and the three-dimensional structure of the shielding cover is formed at one time, avoiding the cumulative error caused by multiple mold changes. The pressure of 200-300MPa is set to allow the AL50 aluminum alloy to fully fill the mold cavity during plastic deformation, avoiding the problems of contour collapse and unclear rounded corners caused by insufficient pressure. The mold temperature is coordinated at 80-120℃ and the plate temperature is controlled at 25±5℃, so that the elongation of the shielding cover is stabilized at more than 15%, avoiding the discrete effect of mechanical properties caused by temperature fluctuations.

[0036] The laser cutting equipment in S3 uses a fiber laser with a power range of 500-1500W, a cutting speed of 10-30mm / s, and nitrogen as the auxiliary gas with a purity of ≥99.99%.

[0037] Specifically, by using a fiber laser with a power of 500-1500W and a cutting speed of 10-30mm / s under the condition of nitrogen purity ≥99.99%, the processing quality and production efficiency of the drone shielding cover were improved.

[0038] S4 includes the following steps: S401, transport the precision-formed AL50 aluminum alloy plate to the bottom of the testing machine via a conveyor belt; S402, the testing machine performs online measurement of the flatness and aperture size of the AL50 aluminum alloy plate, wherein the testing frequency is set to ≥ 20 pieces / minute; S403. The data detected by the detection machine is fed back to the operation console in real time and stored through the operation console.

[0039] Specifically, in step S401, the precision-formed AL50 aluminum alloy plate is transported to the bottom of the inspection machine by a conveyor belt, which improves the processing efficiency compared to traditional manual transportation; In step S402, the AL50 aluminum alloy plate is inspected by a testing machine to ensure that the processed parts meet the specifications of the drone; In step S403, the data is fed back to the operation console in real time and stored, thereby achieving the effect of quality traceability.

[0040] In S5, the anodizing treatment adopts a pulse power supply with a voltage of 15-25V, an electrolyte temperature of 15-25°C, a treatment time of 30-60 minutes, and a surface roughness of the generated oxide layer Ra≤0.8μm.

[0041] Specifically, through the coordination of voltage-temperature-time parameters, an oxide layer with a surface roughness Ra≤0.8μm is formed on the surface of the finished shielding cover, thereby reducing the skin effect loss of high-frequency signal transmission.
