[0076] Bearing housing 25: a block structure, fixed to the top compartment shell 1 on the side, located between the stop plate 13 and the opposite side of the opening of the top compartment shell 1 and close to the stop plate 13, with the lead screw 10 installed inside, providing a bearing mounting position for the lead screw 10 to support and rotate;

[0077] Gear 1 26: A disc-shaped toothed structure, fixed on the output shaft of motor 2 28, meshing with gear 2 27, transmitting the power of motor 2 28 to shaft 18;

[0078] Gear 27: A disc-shaped toothed structure, fixed at one end of the rotating shaft 18 located inside the protective box 2, meshing with gear 1 26, receiving power from motor 28 and driving the rotating shaft 18 to rotate;

[0079] Motor 28: The bottom surface of the main body is fixed to the side opposite to the opening of the protective box 2. The output shaft is connected to gear 1 26 to provide power for the opening and closing action of the cover plate 3.

[0080] Working principle: When the lifting stop plate 13 needs to be raised or lowered, motor 9 starts, and its output shaft drives the two pulleys 7 to rotate synchronously. The power is transmitted to the pulleys 7 on the lead screw 10 through the belt 8, thereby driving the two lead screws 10 to rotate synchronously within the bearing seat 25. Since the slider 11 is connected to the lead screw 10 by a thread, according to the lead screw and nut transmission principle, the slider 11 will move linearly along the axis of the lead screw 10. At this time, the limiting rod 12 on the slider 11 slides within the slot 24 of the square sleeve 22, preventing the slider 11 from rotating with the lead screw 10. On the other hand, it drives the column 14 to rise and fall synchronously within the square sleeve 22. Since the column 14 is fixedly connected to the landing plate 13, the landing plate 13 can rise or fall smoothly to adapt to the take-off and landing altitude requirements of the UAV. The opening and closing of the cover 3 is completed by the flip-cover drive structure and the flip-cover structure working together. After the motor 28 starts, the gear 26 on its output shaft drives the gear 27 to rotate, which in turn drives the rotating shaft 18 to rotate. The rotating shaft 18 converts the rotational motion into a composite motion of translation and rotation of the connecting shaft 6 through the hinged connecting rod 19 and connecting rod 20. The connecting shaft 6 drives The Z-shaped bar 5 moves along with its fixed axis. The sliding shaft 21 on the Z-shaped bar 5 slides within the vertical sliding hole 16 and the arc-shaped sliding hole 17 of the base plate 15. When the cover plate 3 is opened, the connecting shaft 6 drives the sliding shaft 21 to rise along the vertical sliding hole 16 first, and then enter the arc-shaped sliding hole 17, causing the Z-shaped bar 5 to rotate around the sliding shaft 21 as a fulcrum, pushing the cover plate 3 open to both sides of the top compartment outer shell 1. When closing, the motor 28 reverses, and the connecting shaft 6 drives the sliding shaft 21 to retract along the arc-shaped sliding hole 17 back to the vertical sliding hole 16. The Z-shaped bar 5 then resets, and the cover plate 3 finally overlaps the limiting protrusion 4 to complete the closure. To achieve sealed protection of the top compartment, the extension and retraction of the landing plate and the opening and closing of the cover can be linked during the take-off and landing of the drone. Through preset programs or sensor feedback, motor 28 can be started to open the cover 3 before the drone lands. Then motor 9 starts to raise the landing plate 13 to a suitable height. When the drone takes off, motor 9 first lowers the landing plate 13 to a low position, and then motor 28 closes the cover 3. This ensures that the drone completes take-off and landing operations in a safe and enclosed environment, effectively avoiding the cumbersome operation and motion interference problems of traditional independent drive structures.
