본 발명은 전기 구동형 자동차에 전력을 공급하는 송수신 장치에 관한 것으로, 더욱 상세히는 커넥터에 의한 직접 연결 방식이 아닌 전자기 유도에 의한 비접촉 방식으로 전기 자동차에 전력을 공급하는 장치에 관한 것이다.The present invention relates to a transmission and reception device for supplying power to an electrically driven vehicle, and more particularly to a device for supplying power to an electric vehicle in a non-contact manner by electromagnetic induction rather than a direct connection method by a connector.

일반적으로 전기 구동형 자동차에 전력을 공급하기 위한 시스템은 [도 16]에 도시된 바와 같이 플러그인 방식(편의상 종래기술1)으로, 전력공급부(1)에 연결된 전력공급선(111)을 차량의 커넥터(511)와 연결하는 방법으로 차량에 전력을 공급하게 된다.In general, a system for supplying electric power to an electric vehicle is a plug-in method (conventionally known in the art 1), as shown in FIG. 16, by connecting a power supply line 111 connected to the power supply unit 1 to a connector of a vehicle ( 511 to supply power to the vehicle.

하지만 상기 종래 기술1과 같이, 전력공급선(111)과 커넥터(511)를 연결하여, 전력을 공급하게 되면, 매번 사용자에 의해 전력공급(111)과 커넥터(511)의 연결이 이루어져 번거로울 뿐만 아니라 전력공급부(1)의 외부환경(비, 눈, 습기, 과열)에 의한 공급선의 누전이나 단선의 우려가 있다.However, as in the related art 1, when the power supply line 111 and the connector 511 are connected to supply power, the power supply 111 and the connector 511 are connected by the user every time, and the power is not only cumbersome. There is a risk of short circuit or disconnection of the supply line due to the external environment (rain, snow, moisture, overheating) of the supply section 1.

이러한 문제를 극복하기 위해 비접촉 방식으로 전기 자동차에 전력을 공급하 는 방법이 개발되었고, 대한민국 공개특허 제200-88841호(비접촉 3상급전방식을 이용한 전기 차량 운행시스템)와 같이(편의상 종래기술2), 자동차가 주행하는 도로상에 전력송전선을 설치하여 전자기 유도작용에 의해 차량에 전력을 공급하는 기술이 그 한 예이다.In order to overcome this problem, a method of supplying electric power to a non-contact electric vehicle has been developed, and as disclosed in Korean Patent Laid-Open Publication No. 200-88841 (electric vehicle driving system using a non-contact three-phase power feeding method) For example, a technology of supplying power to a vehicle by electromagnetic induction by installing a power transmission line on a road on which a vehicle travels is one example.

또한 전력이 공급되는 상태를 외부에서 확인하기 힘들며, 차량의 전력 충전완료 후에도 전력 송전선이 동작하여, 전력의 낭비를 조장할 수 있다.In addition, it is difficult to check the power supply state from the outside, the power transmission line is operated even after the completion of power charging of the vehicle, it is possible to encourage the waste of power.

더불어 외부에서 사용자의 편의에 따라 전력 공급에 관한 제어가 불가능한 문제점이 있다.In addition, there is a problem that can not control the power supply from the outside in accordance with the user's convenience.

상기 설명한 본 발명에 따른 전기 구동형 자동차를 위한 비접촉 방식의 전력 공급 송수신 장치를 설명하자면 다음과 같다.

[도 2]는 본 발명에 따른 전기 구동형 자동차를 위한 비접촉 방식의 전력 송수신 장치의 실시예를 도시한 도면이다.
[도 3a]는 본 발명에 따른 전기 구동형 자동차를 위한 비접촉 방식의 전력 송신 장치의 실시예를 도시한 도면으로 크게 전력공급부(1); 코일송신부(11, 12) 및 가이드부(3)로 구성된다.
상기 전력공급부(1)는 차량에 전력을 공급하는 역할을 한다.
또한 본 발명의 실시예에서 상기 전력공급부(1)의 몸체외부에 차량에 송신되는 전력에 관한 정보를 표시하는 표시부 및 전력공급부(1)의 동작에 관한 외부 명령을 입력받는 외부입력부(2)를 더 구비하였다.
상기 표시부 및 외부입력부(2)를 더 구비함으로써, 외부에서 전력공급부(1)의 동작을 모니터링하기 용이하며, 전력공급부(1)의 동작을 제어할 수 있는 효과가 있다.
상기 코일송신부(11, 12)는 전력공급부(1)로부터 전달받은 전력을 전자기 유도에 의해 차량에 송신하며, 전류가 흐르면 자기장을 형성한다.
상기 가이드부(3)는 내부에 상기 코일송신부(11, 12)를 포함하고, 전력공급을 위한 차량의 위치를 유도하는 역할을 한다.
상기 가이드부(3)에 관하여 더욱 자세히 설명하자면, 일단부에 두개의 판 형태의 가이드패널이 일정 간격을 두고 배치되며, 전력공급부(1)와 연결되는 타단부가 서로 일체로 결합된다.
또한 [도 3b]에 도시된 바와 같이, 상기 가이드패널의 간격은 차량 하부의 전력 수신 장치의 코일수신부를 수용할 수 있는 간격으로 형성되며, 상기 가이드패널이 서로 마주보는 내벽에 각각 제1코일송신부(11)와 제2코일송신부(12)를 구비한다.
더불어 상기 가이드부(3)의 가이드패널은 일단부로 갈수록 가이드패널간의 간격이 넓어지도록 가이드패널의 너비를 테이퍼지게 형성한다.
상기 가이드패널의 간격의 변화를 주는 이유는 가이드 패널 사이에 위치될 전력 수신 장치의 코일수신부가 진입하기 용이하도록 하기 위함이다.
본 발명에 따른 전력 송신 장치의 첫 번째 실시예에서 상기 가이드부(3)의 두개의 가이드 패널 사이에 제1차량센서부(41)가 형성되었다.
상기 제1차량센서부(41)는 차량(V)의 진입을 감지하는 역할을 하며, 본 발명의 실시예에서는 차량(V)에 형성된 제2차량센서부(42)와 근접해질 경우, 상기 제1코일송신부(11)와 제2코일송신부(12)를 활성화하게 된다.
[도 4a]는 본 발명에 따른 전기 구동형 자동차를 위한 비접촉 방식의 전력 수신 장치의 실시예를 도시한 도면으로, 크게 체결부(59), 연결부(53) 및 코일수신부(51)로 구성된다.
상기 체결부(59)는 차량의 하부에 코일수신부(51)를 체결하는 역할을 하며, 체결 중심축(52)을 기준으로 연결부(53)가 전후 이동이 가능하도록 힌지(hinge)로 연결하고, 상기 힌지를 구동하기 위한 구동모터부(58)가 더 구비되는 것이 바람직하다.
또한, 상기 체결부(59)와 연결부(53)가 연결되는 부분에는 제1탄성부재(521)가 더 구비된다.

본 발명에 따른 전력 수신 장치의 실시예에서 차량의 전력 충전을 위해 차량을 전력 송신 장치에 진입하게 되면, 차량(V)에 구비된 제2차량센서부(42)가 상기 전력 송신 장치의 제1차량센서부(41)를 감지하게 되면, 상기 체결부(59)와 연결된 제1탄성부재(521)에 의하여 연결부의 하강이 이루어진다.
즉, 상기 체결부(59)의 동작에 따라 상기 연결부(53)의 일단부가 차량의 전방향으로 이동하면서, 상기 코일수신부(51)가 하강하게 되는 것이다.
또한, 전력 충전이 완료되면 모터부(58)의 구동에 따른 체결부(59)의 회전운동으로 상기 연결부(53)의 일단부가 차량의 후방향으로 이동과 함께 상기 코일수신부(51)는 상승되어 원상태로 복귀되는 것이다.
상기 연결부(53)는 상기 체결부(59)와 코일수신부(51)를 연결하는 역할을 하며, [도 4b]에 도시된 바와 같이, 적어도 하나 이상의 굴절부(561, 562)를 구비하는 것이 바람직하다.
상기 굴절부(561, 562)는 연결부(53)의 일단부에 외부 힘이 작용하면 상기 굴절부(561, 562)의 중심축을 기준으로 연결부의 하부말단이 좌우로 이동이 가능하며, 본 발명의 실시예와 같이 다수 굴절부(561, 562)를 구비할 경우, 상기 체결부(59)와 코일수신부(51)의 전체 길이를 조절할 수 있는 역할을 할 수 있다.
