Description
Technical Field
[0001] The invention discloses a self-increasing range and long flight time system for a military (civilian) unmanned aerial vehicle, belonging to the technical field of auxiliary power systems for unmanned aerial vehicles. Background Art
[0002] The power systems of current drones, whether military or civilian, limit their range and flight time. Drones have to return mid-flight to replace batteries or refuel, affecting their work efficiency. Summary of the invention
[0003] The purpose of the present invention is to improve the existing UAV power drive mode, provide a UAV self-increasing range and long flight time device, and solve the deficiencies existing in the above-mentioned prior art.

[0005] Figure 2 Structural diagram of the self-increasing range and long flight time system of the unmanned aerial vehicle of the present invention DETAILED DESCRIPTION
[0006] In order to extend the flight time, the current UAV self-extended range and long flight time design is equipped with a generator and an electronic control system. The generator rotor is obtained by extending the UAV motor shaft or the power machine shaft extension device, and the stator is inside the shell. When a small UAV takes off, the motor drives the generator to generate electricity, and when a large UAV is taken off, the engine drives the generator to generate electricity. The electronic control continuously charges the battery and powers the motor, thereby ensuring the long-term flight of the UAV. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] 1. If Figure 1 The military (civilian) unmanned aerial vehicle self-extended range and long flight time system of the present invention is shown. The unmanned aerial vehicle self-extended range and long flight time system includes a set of devices that are extended from the original motor (2) shaft or the power machine shaft, and are installed as a rotor, and the outer shell is installed as a stator to form a generator (1). When the unmanned aerial vehicle motor (2) is working, it drives the generator (1) to generate electricity, and the unmanned aerial vehicle battery (5) is charged or powered by the electronic control system (4) and (3), thereby ensuring the long-term endurance of the unmanned aerial vehicle.
[0008] 2. If Figure 2 As shown, an unmanned aerial vehicle powered by an engine (1) or a battery has an extended engine or motor shaft, a gearbox (2), a generator (3), an electric motor (6) (7), an electronic control system (4), and power transmission (8) (9) to the electric motor. When the electric motor (8) (9) is working, the generator (6) (7) is driven to generate electricity, and the battery pack (10) is charged through the electronic control system (4).
[0009] 3. If Figure 2The engine (1) shown in the figure operates at low speed and low power, driving the generator (3) to generate electricity, which in turn drives the motor (8) (9) to operate, and the operation of (8) (9) drives the generator (6) (7) to generate electricity, thereby ensuring long-term cruising.
[0010] The above are only embodiments of the present invention, but the present invention should not be limited to the contents disclosed in the embodiments, so any equivalents or modifications completed without departing from the disclosed spirit of the principles of the present invention are within the protection scope of the present invention.
