1, Shenzhen Xinnengda Technology Co., LTD. (Power4), as the authorized manufacturer of Apple Inc., was established in 2005, is a high-tech enterprise integrating research and development, design, production and sales. With its leading position in product innovation, Power4 focuses on the development of Apple accessories, such as self-developed AppleLuminous data lines, car charging, wireless charging, etc., with its unique appearance and high-end quality to lead the industry trend.
2, the business scope of Shenzhen Xinnengda Technology Co., Ltd. is: technology development, production and sales of electronic products; Investment in the establishment of industries (specific projects to be declared separately); Enterprise management consulting (excluding talent agency services); Domestic trade, import and export of goods and technologies. (except for items requiring approval before registration as stipulated by laws, administrative regulations and decisions of The State Council).
3, for example, Canada's vivick for the IPAD waterproof case and computer stand, for the iphoneThe series of protective cases designed by 4 mobile phones have passed this certification, which also makes its technology and quality strength a sign.
1, the method of making wireless charger is as follows: Attach the module to the place where the MicroUSB interface is compared. Connect the MicroUSB or Lightning port on the module to your phone. If there is double-sided tape on the receiver, you can glue it directly to the back of the phone. If there is no attached, it is necessary to find a way to luminous type noThe wire is charged . Choose the most suitable position, be careful not to let the part of the connection line have the phenomenon of warping.
2, soldering iron, copper wire, resistor, transistor, capacitor. That will do. So wireless charging is simple. But I suggest you don't do it yourself. It's all special materials. If you do it for fun, just make an oscillating circuit.
3, one of the self-wound coil is connected in the charging circuit, 555 output pin (third pin) is connected to an output tube (oneself at will, but to the high-frequency power tube) the output tube is linked to the self-wound coil, and the two coils will be connectedIn the case of connection, the electrical equipment is charged by means of electromagnetic fields or electromagnetic waves.
The breakthrough of the technology is to find a way to "catch" electromagnetic waves, that is, to use the "resonance" principle of physics - two objects with the same vibration frequency can efficiently transmit energy. The system consists of the main circuit located outside the car and the secondary circuit, rectifier and drive system located inside the car.
The principle of wireless car charger is to use Ampere's law and Faraday's law, through the time-varying magnetic field generated by the power transmitter, in the properly positioned power receiver middleIt generates the electromotive force to charge the phone. The mainstream wireless car charging has two ways of front loading and rear loading. Let's take a look at the principle of wireless car charging.
