A movable plate is fitted onto the surface of the device. One side of the movable plate has a circular hole through which a damping rod, a spring, and an outer cylinder pass. A limit pin is threadedly connected to one side of the movable plate. A sliding groove is formed on one side of the movable plate, and a protective plate is slidably connected inside the sliding groove. The protective plate is made of a transparent material that does not affect the shooting. An adjusting component two is set inside the circular retaining ring. The adjusting component two is the same as the adjusting component one, and includes a slider two, which is slidably connected inside the annular groove. An outer cylinder two is fixedly connected to one side of the slider two, and a damping rod two is fitted inside the outer cylinder two. A clamping block two is fixedly connected to the other end of the damping rod two. The surface of the outer cylinder two... A spring is sleeved on the slider two.

[0027] The usage method and advantages of this utility model: The drone flight collision avoidance device operates as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the L-shaped support column 19 and connecting column 22 are threaded onto the fixed plate 2. Protective plate one 13, protective plate two 14, and protective plate three 21 are respectively installed into the corresponding sliding groove one 309, sliding groove two 409, and pull-out groove 20. The two ends of the connecting ring 8 are respectively engaged with one side of sliding block one 301 and sliding block two 401 via slots, connecting adjusting component one 3 and adjusting component two 4 together, maintaining a certain distance to facilitate clamping of the rotating ring 10, improving user installation convenience, and ensuring tight cooperation between the adjusting components to maintain a stable connection structure. At this time, the positions of moving plate one 306 and moving plate two 406 on telescopic rod one 305 and telescopic rod two 405 are adjusted, thereby adjusting the protective... The positions of plate 13 and the protective plate are adjusted to accommodate cameras 12 of different sizes. Tightening limit pins 307 and 407 limits the movement of plates 306 and 406, keeping them in a fixed position. Pressing springs 304 and 404 causes clamping blocks 308 and 408 to hold the rotating ring 10 in place. As the camera 12 rotates through the rotating ring 10, sliders 301 and 401 in adjusting components 3 and 4 slide within the annular groove 7 of the circular retaining ring 1, causing adjusting components 3 and 4 to rotate. This ensures that the protective plate 13 remains in front of the camera 12, protecting its lens. The protective plate 14 blocks dust, sand, and other foreign objects that may damage the lens, and protects the left and right sides of the camera 12, further improving the safety of the camera 12 in complex flight environments. Below the protective plate 14, a connecting plate 17 and a telescopic plate 18 are connected via a telescopic rod, and a spring 16 is sleeved on the outside of the telescopic rod 15. During the takeoff and landing of the drone 28, this effectively prevents damage to the camera 12 from ground protrusions or debris. When the drone comes into contact with foreign objects during landing, the spring acts as a shock absorber, buffering the impact force on the drone 28. The fixing plate 2 is fixedly installed on the bottom of the drone 28 via the fastener 6 and connecting strap 5, and then secured to the drone 28's arm by the buckle 23. The protective ring 24 is installed around the wing of the drone 28 to prevent obstacles from directly impacting the rotor, thereby avoiding damage to the rotor due to impact and improving the safety and stability of the drone 28 during flight. The support foot 25 is threaded to the bottom of the connecting column 22, and the rubber pad 26 at the bottom of the support foot 25 absorbs shock for the drone 28 when it lands, which helps the drone 28 maintain stability during landing and reduces the risk of fuselage shaking or component damage caused by landing impact. The protective plate 21 and the L-shaped support column 19 are set on the front side of the camera 27 built into the drone 28 to prevent the camera 27 from being damaged by external factors, which effectively ensures the stability of shooting.
