[0027] Refer to Figure 1 - Figure 3, a motor 10 is fixedly connected inside the storage platform 3. The output end of the motor 10 is fixedly connected with a gear 11. A toothed plate 12 is rotatably connected inside the storage platform 3. The gear 11 meshes with the toothed plate 12. Starting the motor 10 drives the gear 11 to rotate through the output end of the motor 10, and then drives the toothed plate 12 to rotate in cooperation with the meshing of the gear 11 and the toothed plate 12. A slide bar 14 is slidably connected inside the toothed plate 12. The top of the slide bar 14 is fixedly connected with a first push plate 15. The upper surface of the first push plate 15 is fixedly connected with a slider 16.

The guiding chute 13 is used to drive the slide bar 14 to move. The movement of the slider 16 drives the second push plate 20 to push the base of the drone. At this time, the spring 19 makes the second push plate 20 drive the sliding seat 17 to slide inside the slider 16. When the second push plate 20 pushes the base of the drone to the middle, it continues to move forward. At this time, the second push plates 20 on the other two sides continue to move forward, so as to stably push the base of the drone to the middle.

[0028] Working principle: When the charging structure of the drone takeoff and landing platform is needed, first, when the drone lands on the upper surface of the storage platform 3, the bracket at the bottom of the drone presses the transmitting coil 7 at this time, so that the pressure sensor 22 with the model of TE Connectivity MS5803-14BA is pressed, and then drives the power control module 21, thereby delivering power to the wireless charging control chip 6, making the transmitting coil 7 generate an electromagnetic field, and then delivering power to the receiving coil inside the drone to achieve the wireless charging effect. At the same time, the power connector 9 and the transmission wire harness 8 can also be manually driven to charge the drone;

[0029] In addition, when the drone lands above the storage platform 3, the motor 10 is activated to drive the gear 11 to rotate, thereby driving the peripheral toothed plate 12 to rotate. At this time, the guide chute 13 inside the toothed plate 12 drives the slide rod 14 and the first push plate 15 to slide inside the storage platform 3, and then drives the four sliding seats 17 to move relatively. At this time, when the sliding seat 17 moves, it will drive the second push plate 20 to fit with the drone, and then push the drone to move towards the middle through the second push plate 20. During this process, due to the expansion and contraction of the spring 19, drones of different shapes or sizes can be pushed to the middle.
