The purpose of the present invention is to provide a wireless charging device for passengers in public transportation. A wireless charger built into a cup holder is disclosed. The wireless charger built into the cup holder according to one embodiment comprises: a cup holder with a circular rim in which a primary coil for inductive coupling to transmit power is embedded; a main body in which a wireless charging module is embedded, wherein the wireless charging module includes a power conversion unit and a control unit, the power conversion unit including an inverter for converting direct current power to alternating current power and a resonance circuit connected to the primary coil, the control unit controlling the power conversion unit to transmit the power to a receiving device wirelessly; and a cover rotatably connected to the main body to cover the cup holder rotatably connected to the main body. The cup holder detachably connected to the main body can maintain any one of the following states: a folding state in which the cup holder maintains a 0-degree angle with the main body; a cup support state in which the cup holder maintains a 90-degree angle; and a charging-enabled state in which the cup holder maintains an angle greater than 90 degrees.

    컵 홀더에 내장된 무선 충전기가 개시된다. 일 실시예에 따른 컵 홀더에 내장된 무선 충전기는, 자기 유도 결합에 의해 전력을 전송하기 위한 1차 코일이 원형 림에 내장된 컵 홀더; 직류 전원을 교류로 변환하기 위한 인버터와 1차 코일에 연결되는 공진 회로를 포함하는 전력 변환부 및 전력 변환부를 제어하여 수신 장치에 전력을 무선으로 전송하기 위한 제어부를 포함하는 무선 충전 모듈이 내장되는 본체; 및 본체에 회동 가능하게 연결된 컵 홀더를 덮기 위해 본체에 회동 가능하게 연결되는 커버를 포함하여 구성될 수 있다. 본체에 회동 가능하게 연결되는 컵 홀더는, 본체와 0도 각도를 유지하는 접힌 상태, 90도 각도를 유지하는 컵 지지 상태 및 90도보다 큰 각도를 유지하는 충전 가능 상태 중 어느 하나의 상태를 유지할 수 있다.
