[0069] The second contact type charging head 708 is electrically connected to the battery in the unmanned aerial vehicle 5.

[0070] When the unmanned aerial vehicle 5 needs to be charged after completing the flight task, the flight control system controls the unmanned aerial vehicle 5 to land slowly on the machine base 4. During the landing process, since the magnet 705 corresponds to the position of the iron ring 709, the two generate mutual attractive magnetic force, guiding the unmanned aerial vehicle 5 to accurately land at the designated position of the machine base 4, so that the first contact type charging head 706 and the second contact type charging head 708 can be smoothly docked. Once the docking is successful, the electric energy of the battery in the vehicle frame 2 is transmitted to the battery in the unmanned aerial vehicle 5 through the connecting line 702, the first contact type charging head 706, the second contact type charging head 708, and the charging of the unmanned aerial vehicle 5 begins.

[0071] In the preferred scheme, the first contact type charging head 706 is slidingly connected to the inside of the plug block 704 and extends to the top of the plug block 704;

[0072] The first contact charging head 706 is provided with a movable column 711 and a reset spring 712 at the bottom;

[0073] The inside of the fixed seat 701 is provided with a tactile sensor 710;

[0077] When the magnet 705 does not contact the iron ring 709, there is a gap between the tactile sensor 710 and the movable column 711.

[0078] During the landing process of the unmanned aerial vehicle 5, when the magnet 705 approaches and starts to contact the iron ring 709, the fixed plate 707 presses down the first contact charging head 706, the first contact charging head 706 slides downward in the plug-in block 704, the reset spring 712 is compressed, and the movable column 711 moves downward with the first contact charging head 706 and contacts the tactile sensor 710. After the tactile sensor 710 detects the contact signal, the signal is transmitted to the control circuit board 703, and after the control circuit board 703 receives the signal, the control circuit board 703 controls the battery in the vehicle frame 2 to start supplying power to the first contact charging head 706, thereby charging the unmanned aerial vehicle 5. When the unmanned aerial vehicle 5 takes off and leaves the landing pad 4, the magnet 705 and the iron ring 709 are separated, the reset spring 712 rebounds, pushes the first contact charging head 706 to move upward to restore the original position, the movable column 711 is separated from the tactile sensor 710, and the control circuit board 703 receives the separation signal to stop supplying power to the first contact charging head 706 to ensure safety and avoid electric leakage.
