Intelligent universal wireless charging system for mobile phone

Abstract

The present invention provides an intelligent universal wireless charging system for a mobile phone. The system comprises a mobile phone wireless charger, a wireless charging battery and a mobile phone wireless charging management terminal. The mobile phone wireless charger is provided with a Bluetooth communication module for information interaction with the mobile phone wireless charging management terminal, and according to basic information of a battery to be charged, a charging mode matching with the battery is selected. The wireless charging battery includes an energy receiving coil, a rectification and filtering circuit and a battery unit. The receiving coil is arranged at the bottom of the wireless charging battery, and is provided with an electromagnetic shielding layer on the back. The mobile phone wireless charging management terminal can detect relative parameters of the battery in real time, and feed the information back to the mobile phone wireless charger by the own Bluetooth module of the mobile phone, thereby facilitating the real-time adjustment of the charging mode and the charging power. Besides, the mobile phone wireless charging management terminal has a charging completion reminding function. The system provided by the invention can be used for wireless charging of mobile phone batteries of different models, and is simple and convenient to operate.

[0002] As a modern communication tool, the mobile phone has already entered people's daily life and plays an extremely important role. However, the current mobile phone mainly adopts wired charging (or conductive charging). This charging method mainly has the following aspects Problems in two aspects: (1) There is a charging wire connected between the charger and the mobile phone, which seriously affects the cleanliness and aesthetics of the environment; (2) The charging interfaces of various types of mobile phones are not uniform, resulting in poor versatility of the charger

[0003] In the prior art, invention patent 201210248190.X discloses a mobile phone wireless charging device, including a power supply, a high-frequency oscillator, a high-frequency power amplifier, a wireless transmitting coil, and a wireless receiving module, which can wirelessly charge various electronic products such as mobile phones. Charging, however, the invention patent does not provide a solution for charging power regulation and mobile phone control terminal

Invention patent 201010501297.1 discloses a wireless rechargeable battery, including a battery unit, a wireless charging module and a switch, which can realize a controllable wireless energy receiving function, but the invention patent does not set an electromagnetic shielding layer between the wireless charging module and the battery unit Therefore, the high-frequency energy signal in the wireless charging module may affect the normal operation of the detection and protection circuits in the battery unit. In addition, the switch is used to control the opening and closing of the wireless charging module. This control method has physical wear and tear. and inconvenient operation
