일반적으로 개인용 이동수단은, 전기를 동력으로 하는 1인용 이동수단으로 전동 휠, 전동 킥보드, 전기 자전거, 초소형 전기차 등을 포함할 수 있다.In general, a personal transportation means is a means of transportation for one person powered by electricity, and may include an electric wheel, an electric kickboard, an electric bicycle, a micro electric vehicle, and the like.
개인용 이동수단으로 많이 사용되는 전동 퀵보드는, 스케이트 보드 모양의 몸체부와, 몸체부의 상측으로 연장되는 지지바와, 지지바의 양측으로 연장되는 손잡이와, 몸체부와 지지바에 회전 가능하게 설치되는 바퀴를 포함할 수 있다.The electric quickboard, which is often used as a personal transportation means, includes a skateboard-shaped body, a support bar extending upwardly of the body, a handle extending to both sides of the support bar, and wheels rotatably installed on the body and the support bar. may include
근래 개인용 이동수단은 회전 동력을 공급하는 모터와, 모터로 전원을 공급하는 배터리를 포함한다.Recently, personal transportation means include a motor for supplying rotational power, and a battery for supplying power to the motor.
종래에는 개인용 이동수단을 사용한 후 길거리에 방치하므로 보행자와 차량의 이동에 방해가 되는 문제점이 있다. 또한 개인용 이동수단의 사용 후 충전이 바로 이루어지지 못하므로 사용상의 불편함이 가중되었다. 또한 바퀴의 사이즈가 상이한 개인용 이동수단을 충전하기 위해서, 바퀴의 사이즈에 따른 충전장치를 별도로 설치해야 하므로 설치비용이 증가하는 문제점이 있다. 따라서 이를 개선할 필요성이 요청된다. Conventionally, there is a problem in that the movement of pedestrians and vehicles is obstructed because it is left on the street after using personal transportation means. In addition, since charging cannot be performed immediately after use of the personal transportation means, inconvenience in use is aggravated. In addition, in order to charge the individual transportation means having different sizes of wheels, a charging device according to the size of the wheels needs to be separately installed, so there is a problem in that the installation cost increases. Therefore, there is a need to improve it.

그리고 수신코일(140)은 제2하우징부(120)의 내측에 위치하며, 수신제어부(130)와 연결될 수 있다. 수신코일(140)과 수신제어부(130)의 사이에는 제2코어부재(124)가 설치되므로, 전원을 공급받는 케이블이 제2코어부재(124)를 통과하여 송신코일(100)과 송신제어부(90)를 연결한다.In addition, the reception coil 140 is located inside the second housing unit 120 , and may be connected to the reception control unit 130 . Since the second core member 124 is installed between the receiving coil 140 and the receiving control unit 130, the cable receiving power passes through the second core member 124 to the transmitting coil 100 and the transmitting control unit ( 90) is connected.
수신코일(140)은 제2코어부재(124)와 제2커버부재(126)의 사이에 위치하며, 코일이 나선형으로 권선된다. 수신코일(140)의 면적은 송신코일(100)의 면적과 같거나 작게 된다. 따라서 수신코일(140)을 포함한 제2충전부(110)가 제1충전부(70)와 일치하지 않아도 송신코일(100)의 내측에 수신코일(140)이 위치할 가능성이 높아지므로, 무선 충전이 보다 신속하고 용이하게 이루어질 수 있다.The receiving coil 140 is positioned between the second core member 124 and the second cover member 126 , and the coil is spirally wound. The area of the receiving coil 140 is equal to or smaller than the area of the transmitting coil 100 . Therefore, even if the second charging unit 110 including the receiving coil 140 does not coincide with the first charging unit 70, the possibility that the receiving coil 140 is located inside the transmitting coil 100 increases, so that wireless charging is more It can be done quickly and easily.
