Description

Technical Field

[0002] The structure of a drone is an unmanned aircraft controlled by a radio remote control device. It can be divided into civil drones and military drones based on its use. Drones have the advantages of being small, low-cost, and flexible, and can achieve rapid vertical take-off and landing. They are widely used in aerial photography, agriculture, surveying and mapping, and wildlife observation. The antenna is one of the most important components of all communication equipment. Its quality is directly related to the terminal's communication capabilities and work efficiency.

[0003] At present, most of the drone antenna structures on the market use an angle adjustment mechanism to adjust the antenna's tilt angle as needed, and by adjusting the antenna's tilt angle, the antenna's communication signal can be optimized. For example, a drone antenna structure disclosed in Chinese patent publication No. CN220420887U, however, has a small angle adjustment range because the antenna's tilt angle can only be adjusted in a single direction. At the same time, the mounting bracket on the antenna structure cannot be replaced, so the antenna structure can only be adapted to one type of drone, resulting in low adaptability of the antenna structure.

[0031] The adjusting mechanism 5 includes a second hollow plate 501, a second open spherical cover 502, a second hollow ball 503, a connecting column 504, a square ring 505, a slider 506, an electric telescopic rod 507 and a connecting block 508. The inner wall of the second hollow plate 501 is fixedly connected to the surface of the second open spherical cover 502, the inner wall of the second open spherical cover 502 is rotatably connected to the surface of the second hollow ball 503, the second hollow ball 503 can rotate freely in the second open spherical cover 502, the inner wall of the second hollow ball 503 is slidably connected to the surface of the cylinder 304, the cylinder 304 can slide freely in the second hollow ball 503, and the two ends of the connecting column 504 are respectively It is fixedly connected to the surface of the second hollow plate 501 and the inner wall of the square ring 505.
