Description

전기 자동차용 충전구 커버Charging port cover for electric vehicle
본 개시는 전기 자동차용 충전구 커버에 관한 것이다.The present disclosure relates to a charging port cover for an electric vehicle.
전기 자동차는 배터리로부터 공급되는 전기 에너지로 전기 모터를 구동한다. 전기 자동차의 예로서, HEV(Hybrid EV), PHEV(Plug-in Hybrid EV), BEV(Battery Electric Vehicle)의 자동차가 있다. HEV(Hybrid EV)는 내연 기관의 동력과 전기 모터의 동력을 조합하여 사용하는 전기 자동차이다. PHEV(Plug-in Hybrid EV)는 HEV의 배터리가 외부의 전원으로부터 충전되도록 설계되는 전기 자동차이다. BEV(Battery Electric Vehicle)는 배터리와 전기 모터로만 구동되는 전기 자동차이다.An electric vehicle drives an electric motor with electric energy supplied from a battery. Examples of the electric vehicle include a hybrid EV (HEV), a plug-in hybrid EV (PHEV), and a battery electric vehicle (BEV) vehicle. An HEV (Hybrid EV) is an electric vehicle that combines power from an internal combustion engine and power from an electric motor. A PHEV (Plug-in Hybrid EV) is an electric vehicle in which the HEV's battery is designed to be charged from an external power source. A BEV (Battery Electric Vehicle) is an electric vehicle powered only by a battery and an electric motor.
HEV, PHEV 및 BEV의 전기 자동차는 공통적으로 전기 에너지를 자동차의 구동에 사용한다. HEV의 전기 자동차의 배터리는 HEV의 자동차 내에서 발전된 전기 에너지로 충전된다. PHEV와 BEV의 전기 자동차의 배터리는 외부로부터 공급되는 전력으로 충전된다.Electric vehicles of HEVs, PHEVs, and BEVs commonly use electric energy to drive the vehicle. The HEV's electric vehicle's battery is charged with electrical energy generated within the HEV's vehicle. The batteries of electric vehicles of PHEVs and BEVs are charged with power supplied from the outside.
PHEV와 BEV와 같은 전기 자동차는, 배터리를 충전시키기 위한 충전구(charging inlet)를 갖는다. 충전구는 휠에 인접한 차체의 부분 또는 차체의 전방 부분 등과 같은 다양한 위치에 배치된다. 충전구는, 개구를 가진 하우징과, 하우징 내에 배치된 충전 포트와, 하우징의 개구를 개폐하는 도어를 포함한다. 충전 포트는 하우징의 개구를 통해 노출된다. 전기 자동차의 배터리를 충전시킬 때, 전기 자동차 충전 시스템에 충전 케이블에 의해 연결되는 충전 플러그가 충전 포트에 분리 가능하게 삽입된다.BACKGROUND Electric vehicles such as PHEVs and BEVs have a charging inlet for charging a battery. The charging ports are disposed at various locations, such as a portion of the vehicle body adjacent to the wheel or a front portion of the vehicle body. The charging port includes a housing having an opening, a charging port disposed in the housing, and a door opening and closing the opening of the housing. The charging port is exposed through an opening in the housing. When charging the battery of the electric vehicle, a charging plug connected by a charging cable to the electric vehicle charging system is detachably inserted into the charging port.
전기 자동차의 배터리를 충전시킬 때, 사용자는 하우징의 도어를 개방하고, 충전 포트를 막고 있는 이물질 방지용 커버 또는 캡을 제거한다. 그 후, 사용자는 충전 플러그를 충전 포트에 맞추고, 배터리의 충전을 실행한다. 배터리의 충전이 완료되면, 충전 포트에 설치된 단자가 빗물이나 먼지와 같은 이물질에 의해 오염되지 않도록, 사용자는 커버 또는 캡을 충전 포트에 다시 결합시켜야만 한다. 종래기술의 전기 자동차용 충전구 커버에 의하면, 사용자는 커버 또는 캡을 제거하거나 다시 장착해야만 한다. 또한, 사용자가 커버 또는 캡을 분실하거나 커버 또는 캡을 재장착하지 않고 도어를 닫을 수도 있다. 이와 같이, 종래기술에 따른 전기 자동차용 충전구 커버는 사용자 편의성 면에서 불리하다.When charging the battery of the electric vehicle, the user opens the door of the housing, and removes the foreign object prevention cover or cap blocking the charging port. After that, the user aligns the charging plug with the charging port, and performs charging of the battery. When the battery is fully charged, the user must reattach the cover or cap to the charging port so that the terminal installed in the charging port is not contaminated by foreign substances such as rainwater or dust. According to the prior art charging port cover for an electric vehicle, the user must remove or reinstall the cover or cap. Also, the user may lose the cover or cap or close the door without reinstalling the cover or cap. As such, the charging port cover for an electric vehicle according to the prior art is disadvantageous in terms of user convenience.
전기 자동차의 배터리를 충전시킬 때 충전구 커버가 분실되지 않도록, 충전 포트를 개폐하는 충전구 커버가 하우징에 힌지에 의해 회전 가능하게 설치될 수 있다. 그러나, 충전구 커버를 하우징에 회전 가능하게 설치하는 것은 큰 설치 공간을 필요로 하며, 전기 자동차의 디자인을 제약한다.In order not to lose the charging port cover when charging the battery of the electric vehicle, the charging port cover for opening and closing the charging port may be rotatably installed in the housing by a hinge. However, rotatably installing the charging port cover on the housing requires a large installation space and limits the design of the electric vehicle.

도 8과 도 9에 도시하는 바와 같이, 충전 플러그(310)가 회전 커버(151, 152)에 가하는 힘에 의해, 한 쌍의 회전 커버(151, 152)는 커버 하우징(120) 내측의 수용 공간(122) 내에서 충전 포트를 향해 회전되기 시작한다. 즉, 한 쌍의 회전 커버(151, 152)는 수용 공간(122)의 좌측 및 우측으로 각각 회전되기 시작한다. 이 때, 도 10과 도 11에 도시하는 바와 같이, 가이드 돌기(163)와 가이드 슬릿(144) 간의 상호 작용에 의해, 슬라이딩 커버(161, 162)는 회전 커버(151, 152)의 회전 중심(RC)을 향해 슬라이드하기 시작한다. 가이드 돌기(163)는 가이드 슬릿(144)의 내단(145)으로부터 외단(146)을 향해 가이드 슬릿(144)을 따라 슬라이드 한다. 가이드 돌기(163)가 내단(145)으로부터 슬라이드함에 따라, 가이드 돌기(163)와 회전 커버(151, 152)의 회전 중심(RC) 간의 거리가 감소된다. 즉, 충전 플러그에 의해 회전 커버(151, 152)가 충전 포트를 향해 회전되면서, 한 쌍의 슬라이딩 커버(161, 162)가 대응하는 회전 커버(151, 152)의 회전 중심(RC)을 향해 슬라이드한다. 이에 따라, 한 쌍의 슬라이딩 커버(161, 162) 간의 간격이 넓어지며, 통과공은 점차 개방된다.As shown in FIGS. 8 and 9 , by the force applied by the charging plug 310 to the rotating covers 151 and 152 , the pair of rotating covers 151 and 152 are accommodating space inside the cover housing 120 . It begins to rotate towards the charging port within 122 . That is, the pair of rotation covers 151 and 152 start to rotate to the left and right of the accommodation space 122 , respectively. At this time, as shown in FIGS. 10 and 11, by the interaction between the guide protrusion 163 and the guide slit 144, the sliding covers 161 and 162 rotate the rotational centers of the rotating covers 151 and 152 ( RC) begins to slide. The guide protrusion 163 slides along the guide slit 144 from the inner end 145 of the guide slit 144 toward the outer end 146 . As the guide protrusion 163 slides from the inner end 145 , the distance between the guide protrusion 163 and the rotation centers RC of the rotation covers 151 and 152 is reduced. That is, as the rotating cover (151, 152) is rotated toward the charging port by the charging plug, a pair of sliding covers (161, 162) slide toward the rotational center (RC) of the corresponding rotating cover (151, 152). do. Accordingly, the gap between the pair of sliding covers 161 and 162 is widened, and the through hole is gradually opened.
슬라이딩 커버(161, 162)가 회전 커버(151, 152)의 내부로 어느 정도 슬라이드하고 회전 커버(151, 152)가 어느 정도 충전 포트를 향해 회전된 상태에서, 충전 플러그(310)를 계속해서 충전 포트(220)를 향해 이동시킨다. 이에 따라, 도 12 내지 도 15에 도시하는 바와 같이, 회전 커버(151, 152)와 슬라이딩 커버(161, 162)는 통과공(121)을 완전히 개방시킨다. 그러므로, 충전 플러그(310)는 충전 포트에 삽입될 수 있고, 전기 자동차의 배터리가 충전될 수 있다. 이 때, 도 14와 도 15에 도시하는 바와 같이, 가이드 돌기(163)는 가이드 슬릿(144)의 외단(146)에 위치하고, 슬라이딩 커버(161, 162)는 회전 커버(151, 152)의 회전 중심(RC)을 향해 최대로 슬라이드되어 있다.In a state in which the sliding covers 161 and 162 slide into the inside of the rotating covers 151 and 152 to some extent and the rotating covers 151 and 152 are rotated toward the charging port to some extent, the charging plug 310 is continuously charged It moves toward the port 220 . Accordingly, as shown in FIGS. 12 to 15 , the rotary covers 151 and 152 and the sliding covers 161 and 162 completely open the through hole 121 . Therefore, the charging plug 310 can be inserted into the charging port, and the battery of the electric vehicle can be charged. At this time, as shown in FIGS. 14 and 15 , the guide protrusion 163 is positioned at the outer end 146 of the guide slit 144 , and the sliding covers 161 and 162 rotate the rotating covers 151 and 152 . It is maximally slid towards the center (RC).
전기 자동차의 배터리의 충전이 완료된 후, 사용자는 충전 플러그(310)를 충전 포트로부터 분리시키고 통과공을 통해 빼낸다. 이에 따라, 충전 플러그(310)는 통과공(121)을 통해 충전 포트로부터 멀어지는 방향으로 이동된다. 충전 플러그(310)가 충전 포트로부터 분리되고 충전 포트로부터 멀어지는 방향으로 이동됨에 따라, 회전 커버(151, 152)는 상기 제1 탄성 부재의 가압력에 의해 통과공(121)을 폐쇄하는 원래의 위치로 회전된다. 또한, 회전 커버(151, 152)의 회전력에 의해, 가이드 돌기(163)가 가이드 슬릿(144)의 외단(146)으로부터 내단(145)을 향해 가이드 슬릿(144)을 따라 슬라이드한다. 가이드 돌기(163)와 회전 커버(151, 152)의 회전 중심 간의 거리가 증가함에 따라, 슬라이딩 커버(161, 162)는 회전 커버(151, 152)의 타측단으로부터 돌출하도록 슬라이드한다. 또한, 이 때, 상기 제2 탄성 부재의 가압력이 슬라이딩 커버(161, 162)의 슬라이드 이동을 돕는다. 충전 플러그(310)가 커버 하우징의 통과공으로부터 완전히 빠져나오면, 통과공은 폐쇄 위치로 회전되어 있는 회전 커버(151, 152)와 서로 접촉한 슬라이딩 커버(161, 162)에 의해 폐쇄된다. 이에 따라, 통과공이 폐쇄되어 있고 커버 하우징이 충전 포트를 덮어 보호하므로, 빗물과 같은 이물질이 커버 하우징의 내부 및 충전 포트로 들어가는 것이 방지된다.After the charging of the battery of the electric vehicle is completed, the user separates the charging plug 310 from the charging port and takes it out through the through hole. Accordingly, the charging plug 310 moves in a direction away from the charging port through the through hole 121 . As the charging plug 310 is separated from the charging port and moved in a direction away from the charging port, the rotating covers 151 and 152 return to the original position for closing the through hole 121 by the pressing force of the first elastic member. rotated In addition, by the rotational force of the rotating covers 151 and 152 , the guide protrusion 163 slides along the guide slit 144 from the outer end 146 to the inner end 145 of the guide slit 144 . As the distance between the guide protrusion 163 and the rotation centers of the rotation covers 151 and 152 increases, the sliding covers 161 and 162 slide to protrude from the other ends of the rotation covers 151 and 152 . In addition, at this time, the pressing force of the second elastic member helps the sliding cover (161, 162) to move. When the charging plug 310 is completely pulled out from the through hole of the cover housing, the through hole is closed by the rotating covers 151 and 152 rotated to the closed position and the sliding covers 161 and 162 in contact with each other. Accordingly, since the through hole is closed and the cover housing covers and protects the charging port, foreign substances such as rainwater are prevented from entering the interior of the cover housing and the charging port.
