Description of the Invention: [Technical Field] The present invention relates to a charging device, and more particularly to an energy conversion charging device. [Prior Art] Natural energy has low pollution, high regeneration, and easy to obtain characteristics, especially wind and solar energy's limited (coal, oil, natural gas) and air pollution caused by coal ash; Or hydropower is limited by terrain and river restrictions, and has a greater incentive to develop wind and solar applications. In particular, the integration of multiple natural sources of energy rather than relying on a single source will ensure the stability and sustainability of the energy supply. In recent years, the development and application of solar power generation has been increasing rapidly. The large-scale establishment of solar film panels to reduce the cost of electricity required for production is also becoming increasingly popular. Creating a low-pollution production environment is the responsibility of enterprises for society, and how to The efficient and extensive conversion of natural energy into electrical energy storage is an important issue for other applications. A illuminating device that uses solar energy as energy is disclosed in U.S. Patent No. 6,994,448. However, because electric energy is a necessary means of driving electronic equipment and electrical appliances, the conventional charging method uses electric power, hydraulic power, and nuclear power to generate electricity, and then achieves charging through transformers, power lines, and sockets. However, the existing charging method is difficult to achieve due to the contact, and it is easy to cause the risk of sparks, electric shock and electric jump. In addition, the power cords and charging equipment required for various electronic and electrical appliances 1361541 P51960131TW 26068twf.doc/n are also different, so the use of a variety of electronic products will cause entanglement of the line, and the area that is restricted due to the source of the power supply and the length of the line. And event space. There has also been some recent research and development regarding the use of wireless charging, for example, US Patent Publication No. 2007/0114967 discloses a light charging device comprising a light source and a sensor connected to the light source. When the sensor debt detects that the portable electronic device with the solar cell as the receiving device approaches the light source, the sensor causes the light source to emit light, and the light emitted by the light source is irradiated to the solar cell in the portable electronic device. So that the portable electronic device starts charging. However, the charging device proposed in the U.S. Patent No. 2007/0114967 uses a solar cell (ph〇t〇v〇ltaic cell) as the receiving end of the energy transfer wheel, and its photoelectric conversion efficiency is low, and the practicality needs to be improved. SUMMARY OF THE INVENTION The present invention provides a natural energy driven charging device including a natural energy conversion module, an energy transmitter, and an energy receiver. The natural energy conversion module is configured to receive a natural energy to form a first electrical energy, and the energy transmitter is configured to receive the first electrical energy and convert the energy into an energy source, and the energy receiver is configured to receive the energy and convert to form a second Electrical energy is used for external devices. The invention further provides a natural energy driven charging device comprising a natural energy conversion module, an electromagnetic wave transmitter and an electromagnetic wave receiver. The above natural energy conversion module is configured to receive a natural energy to form a first electrical energy.
