[0011] 1. The present invention sets a power generation component so that the motor fan can generate current when rotating to power the motor of the air conditioner outdoor unit or charge the storage battery. The motor rotating shaft drives the permanent magnet sheet thereon to rotate on one side of the T-shaped permanent magnet and the copper coil through the T-shaped ring bracket, so that the copper coil generates current for use by the air conditioner or stored in the storage battery, thereby improving the power generation efficiency of the power supply device, reducing the dependence of the air conditioning system on the external power grid, and thus reducing the operating cost of the air conditioner.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example

[0021] The main task of the air conditioner outdoor unit is to release the heat in the refrigerant to the external environment through the condenser. The fan driven by the motor plays a very critical role in this process. Since traditional power supply devices usually use the heat exchange process of the air conditioner itself to generate electricity, but the power generation efficiency is not high, which not only increases the manufacturing cost, but also increases the difficulty of maintaining the power generation device. In order to improve the power generation efficiency of the power supply device and reduce the air conditioning system's dependence on the external power grid, refer to Figure 1 - Figure 3 The present embodiment provides a permanent magnet generator power supply device for rotating the fan of the motor of an air-conditioning outdoor unit, which is composed of a motor housing 4, a motor rotating shaft 5 and a power generation component. The motor rotating shaft 5 is arranged at one end of the motor housing 4 and is fixedly connected to the motor output shaft. The entire power supply device is installed on the outside of the motor housing 4 near one end of the output shaft. It occupies a small space and is very flexible in disassembly and assembly, and does not affect the normal operation of the air-conditioning outdoor unit.

[0022] In order to generate electricity by converting part of the energy generated during the operation of the air conditioner, a power generation component is arranged on the outside of the motor housing 4 and is used to rotate with the motor output shaft to generate electricity. The power generation component includes a T-shaped barrel bracket 3 fixedly installed on the outside of the motor housing 4, and a T-shaped ring bracket 7 fixedly arranged on the motor rotating shaft 5. The T-shaped ring bracket 7 and the T-shaped permanent magnet 1 are made of uniform aluminum alloy, which can enhance the structural strength and stability of the equipment, improve the energy conversion efficiency, and reduce the friction loss between components.

[0023] A plurality of T-shaped permanent magnets 1 distributed in a circular array are fixedly arranged on one side of the T-shaped barrel bracket 3, and the magnetic poles of two adjacent T-shaped permanent magnets 1 are opposite. Copper coils 2 are respectively sleeved on the outer sides of the plurality of T-shaped permanent magnets 1. The copper coils 2 and the T-shaped permanent magnets 1 are integrally glued and fixed by epoxy resin. As a high-strength adhesive material, epoxy resin can provide stable bonding force to ensure that the connection between the copper coil 2 and the T-shaped permanent magnet 1 is more secure and prevent loosening due to vibration or external force. Permanent magnet sheets 6 fixed to the outer side of the T-shaped sleeve bracket 7 are arranged at intervals on one side of the copper coil 2, and the magnetic poles of two adjacent permanent magnet sheets 6 are opposite, which can effectively balance the distribution of the magnetic field and avoid the inhomogeneity of the magnetic field, which helps to generate a more stable magnetic field and optimize the electromagnetic effect inside the generator. The opposite magnetic poles help maintain the symmetry of the magnetic field, which is very important for the operating stability of the generated current and can ensure the uniformity and periodicity of the current generation.

[0024] The copper coil 2 is electrically connected to a voltage-stabilizing rectifier for converting AC power into DC power. The voltage-stabilizing rectifier is electrically connected to a storage battery. AC power is generated in the copper coil 2, and the output of the copper coil 2 usually outputs AC power through two terminals. The AC power input end of the generator, i.e., the AC power output by the copper coil 2, is connected to the AC input end of the voltage-stabilizing rectifier; the AC input end usually has two terminals, which are respectively used to connect the positive and negative ends of the AC power supply. The rectified DC power usually passes through a filter capacitor to reduce fluctuations. These DC power output ends are connected to equipment that requires DC power through cables.

[0025] The storage battery is electrically connected to an inverter for converting AC power into DC power, and the inverter is electrically connected to the motor. When the motor needs additional power supply, the electric energy in the storage battery is supplied to the motor through the inverter. The inverter also includes the function of adjusting voltage and frequency to ensure safe and stable operation of the motor.

[0026] During actual use of the power supply device, the fan is driven by the motor to rotate and work. At the same time, the output shaft of the motor drives the T-shaped ring bracket 7 to rotate, and the T-shaped ring bracket 7 drives several permanent magnetic pieces 6 thereon to rotate. The permanent magnetic pieces 6 rotate on one side of the T-shaped permanent magnetic magnet 1 and the copper coil 2. The rotation of the permanent magnetic pieces 6 will change the direction and strength of the magnetic field passing through the copper coil 2, so that the copper coil 2 generates an induced current, and the current is stored in the battery through the voltage regulator rectifier.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
