DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] First Embodiment

[0024] The endurance of current unmanned aircraft is limited by the battery capacity. Larger or smaller batteries will have a certain impact on the flight time of the unmanned aircraft, thereby reducing the endurance of the unmanned aircraft. In order to extend the flight time and endurance of the unmanned aircraft, reduce the need for frequent charging of the unmanned aircraft, and improve work efficiency, refer to Figure 1 - Figure 3, this embodiment provides an intelligent electronic battery power supply device for the rotation of a drone motor, including the drone motor housing 4 and a rotating vertical shaft 5 installed at the output end of the drone motor. The top of the rotating vertical shaft 5 is fixedly connected to the drone propeller. Both the drone motor and the drone propeller are basic components of existing drones. The power supply device of the present invention converts the originally unused part of mechanical energy into electrical energy through the concept of generating electricity by the rotation of the propeller, utilizes the energy generated by the rotation of the propeller during flight, and then provides supplementary power for the battery or other power systems.

[0025] In order to continuously charge the battery during flight and reduce the burden on the battery, a power generation component is provided on the rotating vertical shaft 5 for generating and storing electrical energy following the rotation of the output end of the drone motor. The power generation component includes a movable annular housing 7 fixedly sleeved on the rotating vertical shaft 5 and a positioning annular housing 3 rotatably arranged at the bottom of the movable annular housing 7. The positioning annular housing 3 is sleeved outside the drone motor housing 4 and fixedly connected thereto. The cross-sections on both sides of the movable annular housing 7 and the positioning annular housing 3 are both set to be Z-shaped, ensuring that the movable annular housing 7 can rotate stably on the positioning annular housing 3, and at the same time sealing the inner sides of the movable annular housing 7 and the positioning annular housing 3. Both the movable annular housing 7 and the positioning annular housing 3 are made of lightweight and high-strength graphene carbon fiber, making the entire power supply device more lightweight, enhancing the structural strength and stability of the entire power supply device, and reducing the frictional loss between components.

[0026] Twelve permanent magnet chips 6 arranged in a circumferential array are fixedly bonded to the bottom of the movable annular housing 7. The permanent magnet chips 6 and the movable annular housing 7 form the rotor of the power generation device. T-shaped permanent magnets 1 are provided at the bottoms of the twelve permanent magnet chips 6. The T-shaped permanent magnets 1 and the positioning annular housing 3 form the stator of the power generation device. The T-shaped permanent magnets 1 are fixedly bonded to the positioning annular housing 3. A surrounding copper coil 2 is sleeved outside the T-shaped permanent magnets 1. The rotor rotates on the stator, and the permanent magnet chips 6 rotate on the T-shaped permanent magnets 1 and the surrounding copper coil 2, generating a changing magnetic field in the surrounding space. When the magnetic field changes, an induced current is generated in the surrounding copper coil 2.

[0027] The permanent magnet slice 6 and the movable annular housing 7, and the T-shaped permanent magnet 1 and the positioning annular housing 3 are all fixed by epoxy resin bonding. As a high-strength bonding material, epoxy resin can provide stable adhesive force, ensuring a more firm connection between the permanent magnet slice 6 and the movable annular housing 7, and between the T-shaped permanent magnet 1 and the positioning annular housing 3, preventing loosening caused by vibration or external force, improving the stability of the fixation of the permanent magnet slice 6 and the T-shaped permanent magnet 1. Moreover, two adjacent permanent magnet slices 6 have opposite magnetic poles, and the permanent magnet slice 6 and the T-shaped permanent magnet 1 with opposite magnetic poles are opposite to each other up and down, which can effectively balance the distribution of the magnetic field, avoid magnetic field non-uniformity, which helps to generate a more stable magnetic field, optimize the electromagnetic action inside the generator. The opposite magnetic poles will help maintain the symmetry of the magnetic field, which is very important for the operating stability of current generation, and can ensure the uniformity and periodicity of current generation.

[0028] Second Embodiment

[0029] To ensure the safe and stable operation of the UAV motor, referring to Figure 1 , on the basis of the first embodiment, in this embodiment, a voltage stabilizing rectifier 8 for converting alternating current into direct current is fixedly installed on one side of the bottom of the positioning annular housing 3, and the surrounding copper coil 2 is electrically connected to the voltage stabilizing rectifier 8. The voltage stabilizing rectifier 8 is also electrically connected to a storage battery. The voltage stabilizing rectifier 8 converts the alternating current generated by the surrounding copper coil 2 into direct current, and then stores the electric energy in the storage battery. The storage battery is electrically connected to an inverter for converting direct current into alternating current, and the inverter is electrically connected to the UAV motor. The direct current in the battery is converted into alternating current by the inverter for use by the UAV motor.

[0030] In the present invention, the movable annular sleeve drives the permanent magnet slice 6 to rotate on the top of the T-shaped permanent magnet 1, which will generate a changing magnetic field in the surrounding space, causing an induced current to be generated in the surrounding copper coil 2. The current is stored in the storage battery through the voltage stabilizing rectifier 8 to supply power to the UAV motor, converting the originally unused part of the mechanical energy into electrical energy, continuously charging the battery during flight, reducing the consumption of battery energy, and extending the flight time and endurance of the UAV.

[0031] During the actual use of this power supply device, the output shaft of the UAV motor rotates, driving the rotating vertical shaft 5 to rotate. The rotating vertical shaft 5 drives the movable annular housing 7 thereon to rotate on the positioning annular housing 3. The movable annular housing 7 drives the permanent magnet slice 6 to rotate above the T-shaped permanent magnet 1, which will generate a changing magnetic field in the surrounding space. When the magnetic field changes, an induced current will be induced in the surrounding copper coil 2. The current is stored in the storage battery through the voltage stabilizing rectifier 8, and then the electric energy of the storage battery is supplied to the UAV motor through the inverter, thereby extending the endurance of the UAV battery.
