摘要
A wireless charging case device and a method thereof which supports to easily wirelessly charge a terminal without having a wireless charging function are provided. A wireless charging case comprises; a front case which covers the front side of a terminal, including a resonance coil which converts a resonance magnetic field into a first power source; a rear case which covers the rear side of a terminal; and a connection member which connects the front case and the rear case to be interlocked. The rear case comprises; an induction coil which converts an induction magnetic field into a second power source; a rectifier which rectifies the first power source or the second power source and performs a smoothing process; a power divider which is connected to the terminal and receives the first power source or the second power source and divides and transfers the power to the terminal; a controller which controls the wireless communications between a wireless power supply device and the terminal; and a wireless communications antenna which transmits and receives a wireless signal between the wireless power supply device and the terminal.;COPYRIGHT KIPO 2014;[Reference numerals] (10) Terminal; (100) Wireless charging case; (101) Resonance coil; (102) Induction coil; (110) Rectifier; (112) First rectification unit; (114) Second rectification unit; (12) Charging terminal; (120) Power distributer; (130) Control unit; (14) Charging control circuit; (140) Wireless communications antenna; (150) Current sensing circuit; (16) Battery; (18) Communications unit; (20) Wireless power supply device
