[0030] The searchlight control box 4 is fixedly connected to the motor 5 , the circuit board 6 and the bottom cover 7 , and the motor 5 and the circuit board 6 are fixed to the inner surface of the searchlight control box 4 .

[0031] The searchlight control box 4 and the device connection port 9 are fixedly connected, and the device connection port 9 is a Type-C interface setting, including an anti-foolproof structure. The searchlight control box 4 and the support rod 10 are fixedly connected, and a threaded hole is set on the inner side of the end of the support rod 10.

[0032] The support rod 10 and the hand screw 11 are threadedly connected, the connecting shaft 13 and the transparent front cover 14 of the searchlight are fixed by bolts, and the transparent front cover 14 of the searchlight and the heat dissipation rear cover 15 of the searchlight are fixed by bolts, and the heat dissipation rear cover 15 of the searchlight is made of metal.

[0033] The transparent front cover 14 of the searchlight is fixedly connected to the light board 16 and the lens 18. A protrusion is arranged in the middle of the surface of one side of the light board 16, and laser lamp beads, RGB color lamp beads and aspherical focusing lenses are arranged on the protrusion.

[0034] Specifically, the structure is composed of a drone body 1, a connection port 2, a screw hole 3, a searchlight control box 4, a motor 5, a circuit board 6, a bottom cover 7, a docking port 8, a device connection port 9, a support rod 10, a hand screw 11, a connecting shaft 13, a searchlight transparent front cover 14, a searchlight heat dissipation rear cover 15, a light board 16 and a lens 18 to form a drone searchlight. The drone searchlight is mainly divided into a searchlight control box 4, a searchlight body and a single-axis stabilization gimbal. The single-axis stabilization gimbal structure is formed by the motor 5, the circuit board 6, the bottom cover 7, the docking port 8, the device connection port 9 and the connecting shaft 13. The heat dissipation rear cover 15, the light board 16 and the lens 18 form a searchlight body, which is used in multiple fields such as agricultural monitoring, search and rescue, and safety inspections through the drone body 1. The drone body 1 and the searchlight control box 4 can be easily assembled as a whole through the connection port 2 and the docking interface 8. The screw hole 3 is used to fix the drone body 1 and the searchlight control box 4. The searchlight control box 4 accommodates internal components such as a motor 5 and a circuit board 6 to protect the internal components. The motor 5 generates power, and the circuit board 6 is integrated into the searchlight system, so that the searchlight body can be connected to the drone body 1 in an integrated manner. The bottom of the searchlight control box 4 is closed by the bottom cover 7, and hollow holes are provided to provide heat dissipation for the circuit board 10. The motor 5, the circuit board 6 and the bottom cover 7 are arranged in sequence inside the searchlight control box 4 from top to bottom. The bottom surface of the bottom cover 7 has a docking interface 8 and a fool-proof design. The top surface of the searchlight control box 4 has a fool-proof design for expanding peripherals. The device connection port 9 is equipped with a dustproof and waterproof cover when not in use, so that the drone equipped with a searchlight can cope with more complex working environments. The support rods 10 on both sides of the searchlight control box 4 are provided with threaded holes for expanding peripherals. The searchlight body is connected to the connecting shaft 13. The two ends of the connecting shaft 13 are fixedly connected in a row, respectively, so that the rotation of the motor 5 can be controlled in the vertical direction, and the lamp body can be controlled to rotate, and the angle can be adjusted from 0° to -90 degrees (negative when viewed from above). In addition, it has the function of gimbal linkage. By controlling the rotation of the camera gimbal of the drone, the motor can be controlled to rotate at the same angle, and the lamp body can be controlled to rotate, so that the light spot illuminated by the searchlight is always located in the center of the drone image transmission screen. The searchlight light source is accommodated by the transparent front cover 14 of the searchlight. The fully transparent front cover design not only enhances the aesthetics of the searchlight, but also improves the firmness and durability of the structure. The fully transparent front cover allows the light to be distributed more evenly, improves the lighting effect, and also makes the searchlight more technological in appearance. The heat dissipation rear cover 15 of the searchlight dissipates heat and fixes the circuit board, and the light source is emitted by the light board 16, so that the drone load combination supports the combined use of multiple load devices. By introducing laser lamp beads, the center brightness is increased by 30%. With the 14° telephoto searchlight design, the effective lighting distance exceeds 200 meters, allowing the drone to effectively illuminate and search at a longer distance, giving the searchlight a variety of warning functions.Users can customize the flash color to meet different warning needs. At the same time, the 90° wide-angle flash design with a maximum power of 15W makes the warning signal clearly visible within a range of 1 km, greatly enhancing the warning and signal transmission capabilities of the drone. Through the lens 18 scattered light source, the traditional 4-piece lens group is upgraded to a 2-piece lens group. This design simplifies the structure and reduces production costs, while increasing the light transmittance by 10%. The lighting effect of the searchlight is significantly improved, making the light more concentrated and brighter, providing more efficient lighting for the drone body 1 to operate at night or in low-light environments, and significantly improving the adaptability of the drone in different tasks and environments.

[0035] Working principle: Align the docking port 8 at the bottom of the searchlight control box 4 with the connection port 2 at the top of the drone body 1, and then align the hand screws 11 on the inner side of the front support rods 10 on both sides of the searchlight control box 4 with the screw holes 3 on the aircraft, and tighten the connection and fixation through threaded connection to form an integrated use. Other drone load devices can be connected through the device connection port 9, docked with the device connection port 9, and connected and fixed with the rear support rods 10 on both sides of the searchlight control box 4 with the hand screws 11, so that the drone searchlight as a whole can combine the searchlight and other load devices together to form a structural design of an integrated device. This design allows users to combine two or more devices according to actual needs, or split them up and use them separately, which greatly improves the flexibility and adaptability of drone load equipment. The drone load combination overall technology not only improves the flexibility and communication efficiency of drone load equipment, but also provides strong technical support for the multi-functional application and mission execution of drones.

[0036] Example 2

[0037] In order to reduce the load of the UAV and improve flight efficiency, lightweight materials can be used to manufacture the shell and internal structure of the searchlight. By optimizing the structural design and reducing unnecessary components and weight, the entire searchlight is made lighter and easier to carry and operate on the UAV; in order to achieve higher flexibility and customizability, a modular design can be adopted. The searchlight is decomposed into multiple independent modules, such as light source module, control module, power module, etc., each of which can be replaced and upgraded independently. This design not only facilitates repair and maintenance, but also allows users to customize searchlights with different configurations according to actual needs to meet different usage requirements. The searchlight uses a high-brightness LED array as a light source, and through precise optical design, it achieves uniform and high-brightness lighting effects. The LED array has the advantages of low energy consumption, long life, and high stability, and can provide reliable lighting services in various environments; in order to improve user experience and convenience of operation, an intelligent control system can be introduced. Through built-in sensors and algorithms, functions such as automatic dimming, color temperature adjustment, and mode switching are realized. Users can remotely control the searchlight through a mobile phone APP or a remote control to achieve a more intelligent operation experience. In addition to basic lighting functions, it can also integrate a variety of practical functions, such as infrared night vision, thermal imaging, etc. The addition of these functions enables the searchlight to play a greater role in night operations, search and rescue, reconnaissance and surveillance, etc. Through lightweight design, modular design, high-brightness LED array, intelligent control system and multi-functional integration and other innovations, it provides a more lightweight, flexible and high-performance solution for drone searchlights.
