본 발명에 따른 실시예는 자동차 주유구 또는 충전포트의 커버 플레이트를 구동하기 위하여, 구동 모터, 출력단이 커버 플레이트의 회전축과 연결된 클러치, 및 구동 모터와 클러치 사이에 연결된 감속기를 포함하여 구성되고, 감속기는 코어축, 코어축 상에 씌워지는 태양 기어, 코어축 상에 씌워지는 유성 캐리어, 유성 캐리어에 조립되되 태양 기어와 치합되는 약간의 유성 기어, 및 각각 유성 기어의 양단에 대응되게 치합되는 고정 내부 링 기어 및 가동 내부 링 기어를 포함하여 구성되며, 고정 내부 링 기어 및 가동 내부 링 기어 중 양자가 서로 등지는 일단에는 각각 제1 단부 커버 및 제2 단부 커버가 형성되고, 제1 단부 커버의 중심에는 통공이 형성되며, 태양 기어의 기어축은 통공으로부터 돌출되어 구동 모터의 출력축과 전동(傳動) 연결되고; 제2 단부 커버의 외측면 중부에는 감속기의 동력 출력단으로서 클러치와 연결되는 돌출축이 형성되는 커버 플레이트 구동 장치를 제공한다. 본 실시예에서 제공되는 구동 장치는 동력 전달 효율이 높고 차지하는 체적이 작다.

    An embodiment according to the present invention provides a cover plate driving device of a vehicle, which is used for driving a cover plate of an oil filling port or a charging port of the vehicle, comprises: a driving motor; a clutch having the output end thereof connected to a rotating shaft of the cover plate; and a speed reducer connected between the driving motor and the clutch. The speed reducer includes: a mandrel; a sun gear covered on the mandrel; a planet carrier covered on the mandrel; several planetary gears assembled on the planet carrier and engaged with the sun gear; and a fixed inner ring gear and a movable inner ring gear engaged to correspond to both ends of the planetary gears, respectively. A first end cover and a second end cover are formed on one end of the fixed inner ring gear and the movable inner ring gear, which face each other on the one end. A through-hole is formed at the center of the first end cover, and the gear shaft of the sun gear protrudes from the through-hole to be connected to the output shaft of the driving motor for power transmission. A protruding shaft, which is connected to the clutch as the power output end of the speed reducer, is formed in a middle part of the outer side surface of the second end cover. The driving device provided by the present embodiment has high power transmission efficiency and occupies a small volume.
