자동차 충전포트도어용 액추에이터 {Actuator for charging port door of vehicle}Actuator for charging port door of vehicle

본 발명은 자동차의 충전포트도어를 개폐시키는 액추에이터에 관한 것으로, 더 상세하게는 충전포트도어를 자동으로 개폐시킬 수 있으면서 상기 충전포트도어의 수동 개폐도 가능하도록 구성되는 자동차 충전포트도어용 액추이이터에 관한 것이다.The present invention relates to an actuator for opening and closing a charging port door of a vehicle, and more particularly, an actuator for a vehicle charging port door configured to automatically open and close the charging port door and also manually open and close the charging port door is about

현재 생산되고 있는 자동차는 기존의 화석 연료를 사용하는 내연기관 방식의 자동차에서 전기 또는 수소를 기반으로 하여 모터를 작동시켜 운행하는 전기 자동차 또는 수소 자동차로 전환되고 있다. 이러한 전기 또는 수소 자동차는 주기적으로 충전을 할 필요가 있는바, 충전을 하기 위한 충전포트 및 이를 보호하기 위한 충전포트도어가 필수적으로 요구되며, 상기 충전포트도어는 여닫이문과 같이 충전포트 입구를 덮거나 개방시킬 수 있는 구조로 장착된다. 한편, 최근 들어서는 충전포트도어 내측에 충전상태 등을 표시하기 위한 디스플레이 장치가 추가되며, 상기 충전포트도어가 별도의 전동 액추에이터에 의해 자동으로 개폐되도록 구성되는 경우가 증가하고 있다.Vehicles currently being produced are being converted from conventional internal combustion engine-type vehicles using fossil fuels to electric vehicles or hydrogen vehicles that operate by operating a motor based on electricity or hydrogen. Such electric or hydrogen vehicles need to be periodically charged, so a charging port for charging and a charging port door for protecting the charging port door are essential, and the charging port door covers the charging port entrance like a hinged door or It is installed in a structure that can be opened. On the other hand, recently, a display device for displaying a charging state, etc. is added to the inside of the charging port door, and the case where the charging port door is configured to be opened and closed automatically by a separate electric actuator is increasing.

충전용 연결 플러그를 연결하기 위한 충전포트는 차량 외측의 오목한 부위에 마련되는 것이 일반적이며, 상기 충전포트가 마련되는 오목한 부위는 차량의 디자인을 고려하여 충전포트도어에 의해 덮여 가려지도록 설계된다. The charging port for connecting the charging connection plug is generally provided in a concave portion on the outside of the vehicle, and the concave portion in which the charging port is provided is designed to be covered and covered by the charging port door in consideration of the design of the vehicle.

한편, 상기 충전포트도어가 전동 액추에이터에 의해 회전되도록 구성되는 경우에는, 상기 충전포트도어의 회전축이 전동 액추에이터의 구동축에 기어결합 구조로 연결되는 경우가 일반적인데, 이와 같은 경우 상기 충전포트도어를 차량 외부에서 수동으로 열고 닫을 수 없을 뿐만 아니라, 상기 전동 액추에이터에서 출력되는 회전력이 과도하게 큰 경우 충전포트도어가 손상될 수 있다는 단점이 있다.On the other hand, when the charging port door is configured to be rotated by an electric actuator, it is common that the rotating shaft of the charging port door is connected to the driving shaft of the electric actuator in a gear-engaged structure. In addition to being unable to manually open and close from the outside, there is a disadvantage that the charging port door may be damaged if the rotational force output from the electric actuator is excessively large.

또한 종래의 충전포트도어용 액추에이터는 빗물이나 이물질이 내부로 유입되어 쉽게 손상될 수 있고, 상기 충전포트도어의 개폐 여부를 감지하는 기능이 없다는 단점이 있다.In addition, the conventional actuator for the charging port door may be easily damaged by rainwater or foreign substances flowing into it, and has a disadvantage in that it does not have a function to detect whether the charging port door is opened or closed.

일반적으로 전기차나 수소차에는 배터리 충전을 위한 충전포트가 구비되며, 상기 충전포트가 외부로 직접 노출되지 아니하도록 상기 충전기가 설치된 부위를 덮기 위한 충전포트도어가 마련된다.In general, a charging port for charging a battery is provided in an electric vehicle or a hydrogen vehicle, and a charging port door is provided to cover a portion where the charger is installed so that the charging port is not directly exposed to the outside.

본 발명에 의한 자동차 충전포트도어용 액추에이터는 상기와 같은 충전포트도어를 전동식으로 개폐하기 위한 것으로서, 충전포트도어를 자동으로 개폐시킬 수 있을 뿐만 아니라 수동으로도 개폐 가능하도록 구성된다는 점에 가장 큰 특징이 있다.The actuator for a vehicle charging port door according to the present invention is for electrically opening and closing the charging port door as described above. There is this.

즉, 본 발명에 의한 자동차 충전포트도어용 액추에이터는, 내부공간을 구비하되 바닥면에 관통공(112)이 형성되는 하우징(100)과, 수직으로 세워져 상기 하우징(100) 내부에 자전 가능한 구조로 장착되되 하단이 상기 관통공(112)을 통해 외부로 노출되어 자동차 충전포트도어의 회전축에 연결되며 중단에 플랜지가 형성되는 회전샤프트(200)와, 상기 회전샤프트(200)의 중단을 둘러싸는 링 형상으로 형성되어 상기 플랜지 상에 안착되는 클러치기어(300)와, 상기 회전샤프트(200)의 중단이 삽입되는 링 형상으로 형성되어 상기 클러치기어(300) 상에 안착되며 내측벽이 상기 회전샤프트(200)의 외측면에 결합되어 상기 회전샤프트(200)와 일체로 회전되는 클러치플레이트(400)와, 상기 클러치기어(300)를 향하는 방향으로 상기 클러치플레이트(400)에 탄성력을 인가하는 탄성수단(500)과, 상기 클러치기어(300)를 회전시키는 구동모터(600)를 포함하여 구성된다는 점에 구성상의 특징이 있다.That is, the actuator for a vehicle charging port door according to the present invention includes a housing 100 having an internal space but having a through-hole 112 formed on the bottom, and is vertically erected and rotated inside the housing 100. A ring enclosing the middle of the rotating shaft 200, which is mounted, the lower end is exposed to the outside through the through hole 112, is connected to the rotating shaft of the vehicle charging port door, and a flange is formed in the middle, and the middle of the rotary shaft 200 The clutch gear 300 is formed in a shape and is seated on the flange, and the middle part of the rotary shaft 200 is formed in a ring shape to be inserted and is seated on the clutch gear 300, and the inner wall is the rotary shaft ( 200) coupled to the outer surface of the clutch plate 400 rotated integrally with the rotary shaft 200, and elastic means for applying an elastic force to the clutch plate 400 in the direction toward the clutch gear 300 ( 500) and a driving motor 600 for rotating the clutch gear 300 is characterized in its configuration.

상기와 같이 본 발명에 의한 자동차 충전포트도어용 액추에이터는, 구동모터(600)에서 출력되는 회전력이 다수 개의 동력전달기어(610)를 통해 클러치기어(300)로 전달되고, 클러치기어(300)로 전달된 회전력은 클러치기어(300)와 클러치플레이트(400) 간의 마찰력에 의해 상기 클러치플레이트(400)로 전달되며, 클러치플레이트(400)로 전달된 회전력은 회전샤프트(200)를 통해 충전포트도어를 회전시키도록 사용된다. 이와 같이 클러치기어(300)와 클러치플레이트(400)가 클러치 방식의 동력전달 구조를 갖게 되면, 사용자가 충전포트도어를 수동으로 회전시키는 힘의 크기가 클러치기어(300)와 클러치플레이트(400) 간의 마찰력보다 큰 경우 상기 클러치기어(300)와 클러치플레이트(400) 사이에서 미끄럼운동이 발생하게 되어, 상기 클러치플레이트(400)는 충전포트도어를 따라 회전하지만 클러치기어(300)는 회전하지 아니하게 된다. 즉, 사용자가 수동으로 충전포트도어를 회전시키는 힘은 회전샤프트(200) 및 이에 결합된 클러치플레이트(400)까지만 전달되고 클러치기어(300), 동력전달기어(610), 구동모터(600) 측으로는 전달되지 아니하므로, 사용자는 충전포트도어를 수동으로 개폐시키더라도 구동모터(600)가 외력에 의해 손상될 우려가 없어진다는 장점이 있다.As described above, in the actuator for a vehicle charging port door according to the present invention, the rotational force output from the driving motor 600 is transmitted to the clutch gear 300 through a plurality of power transmission gears 610 , and to the clutch gear 300 . The transmitted rotational force is transmitted to the clutch plate 400 by friction between the clutch gear 300 and the clutch plate 400 , and the rotational force transmitted to the clutch plate 400 is the charging port door through the rotational shaft 200 . used to rotate. As such, when the clutch gear 300 and the clutch plate 400 have a clutch-type power transmission structure, the magnitude of the force for the user to manually rotate the charging port door is determined between the clutch gear 300 and the clutch plate 400 . When the frictional force is greater than the frictional force, a sliding motion occurs between the clutch gear 300 and the clutch plate 400, and the clutch plate 400 rotates along the charging port door, but the clutch gear 300 does not rotate. . That is, the force that the user manually rotates the charging port door is transmitted only to the rotary shaft 200 and the clutch plate 400 coupled thereto, and is directed toward the clutch gear 300 , the power transmission gear 610 , and the driving motor 600 . is not transmitted, so even if the user manually opens and closes the charging port door, there is an advantage that the drive motor 600 is not likely to be damaged by an external force.

한편, 클러치플레이트(400)와 클러치기어(300)가 평평한 원판 형상으로 형성되어 상기 클러치플레이트(400)의 저면이 클러치기어(300)의 상면에 안착되도록 구성되면, 클러치플레이트(400)와 클러치기어(300) 간의 접촉면적이 좁아지므로 동력전달이 정상적으로 이루어지지 아니할 우려가 있다. 물론, 클러치플레이트(400)와 클러치기어(300)를 크게 제작하면 동력전달성능이 우수해지지만, 이와 같은 경우 액추에이터가 대형화된다는 문제가 발생한다.On the other hand, when the clutch plate 400 and the clutch gear 300 are formed in a flat disk shape so that the lower surface of the clutch plate 400 is seated on the upper surface of the clutch gear 300, the clutch plate 400 and the clutch gear Since the contact area between the 300 is narrowed, there is a fear that power transmission may not be performed normally. Of course, if the clutch plate 400 and the clutch gear 300 are made large, the power transmission performance is excellent, but in this case, a problem occurs that the actuator is enlarged.

따라서 본 발명에 의한 자동차 충전포트도어용 액추에이터는 상기 클러치플레이트(400)와 클러치기어(300)의 외경이 증가하지 아니하더라도 클러치플레이트(400)와 클러치기어(300) 간의 접촉면적이 증가하도록 구성됨이 바람직하다.Therefore, the actuator for a vehicle charging port door according to the present invention is configured to increase the contact area between the clutch plate 400 and the clutch gear 300 even if the outer diameters of the clutch plate 400 and the clutch gear 300 do not increase. desirable.

예를 들어, 상기 클러치기어(300)는 내측벽의 전체 또는 일부가 하측으로 갈수록 내경이 좁아지는 방향으로 경사지게 형성되고, 상기 클러치플레이트(400)는 외측벽이 하측으로 갈수록 좁아지는 방향으로 경사지게 형성되어 상기 클러치기어(300)의 내측벽에 면접촉을 하도록 안착될 수 있다. 이와 같이 클러치기어(300)의 내측벽과 클러치플레이트(400)의 외측벽이 비스듬히 경사지게 형성되면, 도 6에 도시된 바와 같이 클러치플레이트(400)가 클러치기어(300) 상에 안착되었을 때 클러치플레이트(400)의 경사진 외측벽이 클러치기어(300)의 경사진 내측벽에 접하게 되는바, 클러치플레이트(400)와 클러치기어(300) 간의 접촉면적이 넓어진다는 장점이 있다.For example, all or part of the inner wall of the clutch gear 300 is inclined in a direction in which the inner diameter becomes narrower toward the lower side, and the clutch plate 400 is inclined in a direction in which the outer wall becomes narrower toward the lower side. It may be seated so as to make surface contact with the inner wall of the clutch gear 300 . As such, when the inner wall of the clutch gear 300 and the outer wall of the clutch plate 400 are formed obliquely, as shown in FIG. 6, when the clutch plate 400 is seated on the clutch gear 300, the clutch plate ( Since the inclined outer wall of 400 is in contact with the inclined inner wall of the clutch gear 300 , there is an advantage in that the contact area between the clutch plate 400 and the clutch gear 300 is widened.

또한, 클러치플레이트(400)와 클러치기어(300) 간의 접촉면이 경사지게 형성되면, 탄성수단(500)이 클러치플레이트(400)를 하향 가압하였을 때 상기 클러치플레이트(400)가 쐐기와 같이 클러치기어(300)의 내측면에 압착되는바, 클러치플레이트(400)와 클러치기어(300) 간의 동력전달 성능이 우수해진다는 장점도 있다.In addition, when the contact surface between the clutch plate 400 and the clutch gear 300 is formed to be inclined, when the elastic means 500 presses the clutch plate 400 downward, the clutch plate 400 becomes the clutch gear 300 like a wedge. .

한편, 본 발명에 의한 자동차 충전포트용 액추에이터는, 클러치기어(300)가 회전샤프트(200)와 일체로 회전될 수 있도록 즉, 회전샤프트(200)와 클러치기어(300) 간의 접촉면적이 증가될 수 있도록, 상기 회전샤프트(200)는 하측 외주면을 둘러싸는 안착판(210)을 구비하되 상기 안착판(210)의 상면 가장자리로부터 상향으로 돌출되어 평면형상이 링 형상을 이루는 삽입돌부(212)를 더 포함하고, 상기 클러치기어(300)는 상기 안착판(210)의 상면에 안착되되 상기 삽입돌부(212)가 인입되는 삽입홈(310)이 저면에 형성될 수 있다.On the other hand, in the actuator for a vehicle charging port according to the present invention, the contact area between the rotating shaft 200 and the clutch gear 300 is increased so that the clutch gear 300 can rotate integrally with the rotating shaft 200 . In order to do this, the rotary shaft 200 has a seating plate 210 surrounding the lower outer circumferential surface, but protrudes upward from the upper surface edge of the seating plate 210 to form an insertion protrusion 212 in a planar shape to form a ring shape. Further, the clutch gear 300 may be seated on the upper surface of the seating plate 210 and an insertion groove 310 into which the insertion protrusion 212 is inserted may be formed on the bottom surface.

이와 같이 안착판(210)의 삽입돌부(212)가 클러치기어(300)의 삽입홈(310)에 삽입되면, 회전샤프트(200)와 클러치기어(300) 간의 접촉면적이 현저히 증가하게 되는바, 회전샤프트(200)와 클러치기어(300)가 보다 확실하게 일체로 회전될 수 있다는 장점이 있다.As such, when the insertion protrusion 212 of the seating plate 210 is inserted into the insertion groove 310 of the clutch gear 300, the contact area between the rotary shaft 200 and the clutch gear 300 is significantly increased. There is an advantage that the rotating shaft 200 and the clutch gear 300 can be rotated integrally more reliably.

더 나아가 상기 삽입돌부(212)는 쐐기 형상으로 삽입홈(310)에 압입되도록 구성될 수도 있다. 예를 들어 상기 삽입돌부(212)는 끝단으로 갈수록 두께가 좁아지도록 외벽의 전체 또는 일부가 경사지게 형성되고, 상기 삽입홈(310)은 상기 삽입돌부(212)의 경사진 외벽과 면접촉을 이루도록 내벽의 전체 또는 일부가 경사지게 형성될 수 있다. 이와 같이 삽입돌부(212)의 외벽과 삽입홈(310)의 내벽이 경사지게 형성되면, 상기 삽입돌부(212)가 쐐기와 같이 삽입홈(310)에 압압되는바, 회전샤프트(200)와 클러치기어(300) 간의 결합력이 더욱 높아진다는 장점이 있다.Furthermore, the insertion protrusion 212 may be configured to be press-fitted into the insertion groove 310 in a wedge shape. For example, the insertion protrusion 212 has an inner wall such that the entire or part of the outer wall is inclined so that the thickness becomes narrower toward the end, and the insertion groove 310 is in surface contact with the inclined outer wall of the insertion protrusion 212 . All or part of may be formed to be inclined. As such, when the outer wall of the insertion protrusion 212 and the inner wall of the insertion groove 310 are formed to be inclined, the insertion protrusion 212 is pressed into the insertion groove 310 like a wedge, and the rotary shaft 200 and the clutch gear There is an advantage that the bonding force between the 300 is further increased.

본 실시예에서는 상기 삽입돌부(212)의 일측 외벽 일부만 경사지게 형성되고, 상기 삽입홈(310) 역시 일측 내벽 일부만 경사지게 형성되는 경우만을 도시하고 있으나, 상기 삽입돌부(212)와 삽입홈(310)은 일측 외벽과 일측 내벽 전체가 경사지게 형성되거나, 양측 외벽과 양측 내벽 전체 또는 일부가 경사지게 형성될 수도 있다.In this embodiment, only a part of the outer wall of one side of the insertion protrusion 212 is inclined, and only a part of the inner wall of one side of the insertion groove 310 is also formed to be inclined, but the insertion protrusion 212 and the insertion groove 310 are The one outer wall and the one inner wall may be formed to be all inclined, or all or part of the both outer walls and both inner walls may be formed to be inclined.

한편, 본 발명에 의한 자동차 충전포트도어용 액추에이터는 상기 탄성수단(500)이 클러치플레이트(400)에 안정적으로 하향 탄성력을 인가할 수 있도록, 상기 회전샤프트(200) 중 상기 플랜지로부터 상측으로 이격된 지점에 설치되는 스토퍼를 추가로 구비하고, 상기 탄성수단(500)은 상기 회전샤프트(200)를 둘러싸는 코일스프링 형상으로 형성되어 상기 스토퍼와 클러치플레이트(400) 사이에 압축 상태로 장착됨이 바람직하다. 이와 같이 상기 탄성수단(500)이 코일스프링 형상으로 형성되면, 클러치플레이트(400)의 상면 전체에 걸쳐 탄성력을 고르게 인가할 수 있으므로, 클러치플레이트(400)의 외측벽 전체가 클러치기어(300)의 내측벽 전체에 고르게 압착될 수 있다는 장점이 있다.On the other hand, the actuator for a vehicle charging port door according to the present invention is spaced upward from the flange of the rotary shaft 200 so that the elastic means 500 can apply a downward elastic force to the clutch plate 400 stably. It is preferable that a stopper installed at a point is additionally provided, and the elastic means 500 is formed in a coil spring shape surrounding the rotary shaft 200 and is mounted in a compressed state between the stopper and the clutch plate 400 . do. As such, when the elastic means 500 is formed in the shape of a coil spring, elastic force can be evenly applied over the entire upper surface of the clutch plate 400 , so that the entire outer wall of the clutch plate 400 is inside the clutch gear 300 . The advantage is that it can be compressed evenly over the entire sidewall.

또한, 본 발명에 의한 자동차 충전포트도어용 액추에이터에 포함되는 하우징(100)은 내부공간에 여러 종류의 구성요소를 설치하거나 유지 보수하는 작업이 용이해지도록, 상측이 개방된 내부공간을 구비하는 하부하우징(110)과, 상기 하부하우징(110)의 상부를 덮는 상부하우징(120)으로 구성될 수 있다. 이와 같이 하우징(100)이 하부하우징(110)과 상부하우징(120)으로 구분되는 경우, 회전샤프트(200)의 하단을 외부로 노출시키기 위한 관통공(112)은 하부하우징(110)의 바닥판에 형성되어야 할 것이다.In addition, the housing 100 included in the actuator for the vehicle charging port door according to the present invention has a lower portion having an inner space with an open upper side so that it is easy to install or maintain various types of components in the inner space. It may be composed of a housing 110 and an upper housing 120 covering an upper portion of the lower housing 110 . As such, when the housing 100 is divided into the lower housing 110 and the upper housing 120 , the through hole 112 for exposing the lower end of the rotary shaft 200 to the outside is the bottom plate of the lower housing 110 . should be formed in

한편, 하부하우징(110)과 상부하우징(120)이 각각 별도로 제작된 후 결합되도록 구성되면, 하부하우징(110)과 상부하우징(120)이 결합부위를 통해 물이나 먼지 등과 같은 이물질이 유입될 우려가 있다. 따라서 상기 하우징(100)은, 상기 하부하우징(110)과 상기 상부하우징(120)이 접하는 부위에 압입되는 하우징씰(130)을 더 포함하여 구성됨이 바람직하다.On the other hand, if the lower housing 110 and the upper housing 120 are separately manufactured and then configured to be combined, the lower housing 110 and the upper housing 120 are connected to each other through the coupling portion, so that foreign substances such as water or dust may be introduced. there is Accordingly, it is preferable that the housing 100 further includes a housing seal 130 that is press-fitted to a portion where the lower housing 110 and the upper housing 120 contact each other.

도 7은 본 발명에 의한 자동차 충전포트도어용 액추에이터에 포함되는 인쇄회로기판(800)과 포텐시오미터(900)의 결합구조를 도시하는 사시도이다.7 is a perspective view showing a coupling structure of the printed circuit board 800 and the potentiometer 900 included in the actuator for the vehicle charging port door according to the present invention.

본 발명에 의한 충전포트도어용 액추에이터는 구동모터(600)에 의해 회전샤프트(200)가 회전될 수 있을 뿐만 아니라, 사용자가 차량 외부에서 충전포트도어를 수동으로 개폐시키는 동작에 의해서도 회전될 수 있다. The actuator for the charging port door according to the present invention can be rotated not only by the rotation shaft 200 by the driving motor 600, but also by the operation of the user manually opening and closing the charging port door from the outside of the vehicle. .

따라서 구동모터(600)의 동작만으로는 충전포트도어의 개폐여부를 정확하게 판단할 수 없으므로, 본 발명에 의한 자동차 충전포트도어용 액추에이터는 회전샤프트(200)의 회전각도를 감지하여 충전포트도어의 개폐여부를 판단하는 포텐시오미터(900)(potentiometer)를 추가로 구비할 수 있다. Therefore, since it is not possible to accurately determine whether the charging port door is opened or closed only by the operation of the driving motor 600, the actuator for the vehicle charging port door according to the present invention detects the rotation angle of the rotating shaft 200 to open or close the charging port door. A potentiometer 900 for determining (potentiometer) may be additionally provided.

상기 포텐시오미터(900)는 상기 회전샤프트(200)의 상측을 둘러싸도록 장착되어, 상기 회전샤프트(200)가 어느 방향으로 어느 각도만큼 회전되었는지를 정확하게 판단할 수 있다. 이때, 회전 대상의 회전방향 및 회전각도를 감지하는 포텐시오미터(900)는 다양한 분야에서 상용화되어 있는바, 상기 포텐시오미터(900)의 내부 구성 및 작동원리에 대한 상세한 설명은 생략한다.The potentiometer 900 is mounted to surround the upper side of the rotary shaft 200 , and it is possible to accurately determine in which direction and by which angle the rotary shaft 200 is rotated. At this time, the potentiometer 900 for sensing the rotation direction and rotation angle of the rotating object is commercialized in various fields, and detailed description of the internal configuration and operating principle of the potentiometer 900 will be omitted.

또한, 상기 포텐시오미터(900)로 전원을 공급하고 상기 포텐시오미터(900)와 신호를 주고 받을 수 있도록, 상기 하우징(100)의 천장면에는 인쇄회로기판(800)이 장착될 수 있다. 이때 상기 회전샤프트(200)가 회전하더라도 포텐시오미터(900)는 고정된 상태를 유지할 수 있도록, 상기 포텐시오미터(900)는 상기 인쇄회로기판(800)에 고정결합됨이 바람직하다. 한편, 상기 포텐시오미터(900)는 회전샤프트(200)의 회전방향 및 각도를 정확하게 측정할 수 있으면서 인쇄회로기판(800)에 결합되어 고정될 수 있다면, 어떠한 형상 및 구조로도 대체될 수 있다.In addition, a printed circuit board 800 may be mounted on the ceiling surface of the housing 100 so as to supply power to the potentiometer 900 and transmit and receive signals to and from the potentiometer 900 . At this time, it is preferable that the potentiometer 900 is fixedly coupled to the printed circuit board 800 so that the potentiometer 900 can be maintained in a fixed state even when the rotating shaft 200 rotates. On the other hand, if the potentiometer 900 can accurately measure the rotational direction and angle of the rotating shaft 200 and can be fixedly coupled to the printed circuit board 800, it can be replaced with any shape and structure. .

도 8 및 도 9는 오링홀더(710)와 오링(720)과 메탈부시(730)의 결합구조를 도시하는 분해사시도이다.8 and 9 are exploded perspective views showing the coupling structure of the O-ring holder 710, the O-ring 720, and the metal bush 730.

회전샤프트(200)는 하부하우징(110)의 바닥에 형성된 관통공(112)을 통해 외부로 노출되는 하단이 충전포트도어의 회전축과 연결되도록 구성되는데, 상기 관통공(112)과 회전샤프트(200) 하단 사이가 이격되면 이격된 틈새를 통해 각종 이물질이 유입될 우려가 있다. 또한 회전샤프트(200)의 하단이 관통공(112)에 끼워맞춤 방식으로 삽입되면 이물질 유입 우려가 감소하지만, 상기 회전샤프트(200)가 원활하게 회전하지 못하게 된다는 문제점이 있다.The rotary shaft 200 is configured such that the lower end exposed to the outside through the through hole 112 formed in the bottom of the lower housing 110 is connected to the rotary shaft of the charging port door, the through hole 112 and the rotary shaft 200 ) If the lower part is spaced apart, there is a risk that various foreign substances may enter through the spaced gap. In addition, when the lower end of the rotary shaft 200 is inserted into the through hole 112 in a fitting manner, the risk of inflow of foreign substances is reduced, but there is a problem that the rotary shaft 200 cannot rotate smoothly.

따라서 본 발명에 의한 자동차 충전포트도어용 액추에이터는 회전샤프트(200)가 용이하게 회전될 수 있으면서 하우징(100) 내부로 이물질이 유입되지 아니하도록, 상기 회전샤프트(200)의 하단을 둘러싸도록 결합되는 오링홀더(710)와, 상기 오링홀더(710)의 외측벽을 둘러싸도록 장착되는 하나 이상의 오링(720)과, 외측면이 상기 관통공(112)의 내측면에 밀착되는 링 형상으로 형성되며 내측면에 상기 오링(720)이 압착되는 메탈부시(730)를 추가로 구비할 수 있다.Therefore, the actuator for a vehicle charging port door according to the present invention is coupled to surround the lower end of the rotary shaft 200 so that the rotary shaft 200 can be easily rotated and foreign substances are not introduced into the housing 100.
