Description

자동차용 언더 커버 및 이를 포함하는 자동차Undercover for automobiles and automobiles comprising the same
본 발명은 자동차에 관한 것이며, 보다 구체적으로 엔진 룸의 하부를 덮는 언더 커버 및 이를 포함하는 자동차에 관한 것이다.The present invention relates to a motor vehicle, and more particularly, to an under cover covering a lower portion of an engine room and an automobile including the same.
통상 자동차의 엔진 룸의 하부는 외부에 노출되어 있으며 엔진 변속기 등 엔진 룸에 장착되는 여러 부속품들의 하부가 외부로 노출되는 구조를 가진다.In general, the lower part of the engine room of an automobile is exposed to the outside, and has a structure in which the lower parts of various accessories mounted in the engine room such as an engine transmission are exposed to the outside.
이와 같은 엔진 룸의 구조는 차량 주행 시 공기 저항이 높아져 연비를 저하시키고 소음을 유발하게 된다.Such a structure of the engine room increases air resistance while driving the vehicle, thereby lowering fuel efficiency and causing noise.
이러한 문제를 해결하기 위해 차량의 엔진 룸 하부에 언더 커버(under cover)를 장착하는 기술이 알려진 바 있다.In order to solve this problem, a technique for mounting an under cover under the engine room of the vehicle has been known.
그러나 엔진 룸 하부에 언더 커버를 설치하는 경우 차량의 라디에이터 그릴을 통해서 엔진 룸으로 유입된 공기가 외부로 효과적으로 배출되지 못하게 되고, 이로 인해 엔진 룸 내부의 공기가 정체되어 압력이 증가하고 온도가 상승하는 문제점이 있었다.However, when the under cover is installed in the lower part of the engine room, the air flowing into the engine room through the radiator grille of the vehicle is not effectively discharged to the outside, which causes the air inside the engine room to stagnate, increasing pressure and increasing temperature. There was a problem.
또한 차량의 엔진 룸 내부의 공기 유동을 조절할 수 있도록 엔진 룸 입부에 액티브 에어 플랩(active air flap)을 설치하여 엔진 룸으로의 공기 유입을 조절하는 기술이 소개된 바 있다. 그러나 이 경우 엔진 룸 입구에서만의 유량 조절로는 엔진 룸 내부의 온도를 섬세하게 조절하기 어렵고, 특히 언더 커버가 설치되는 경우에는 엔진 룸 내부에 공기가 정체되어 유량 조절이 더욱 어렵게 되는 문제가 있다.In addition, a technique for controlling air inflow into the engine room by introducing an active air flap in the engine room to control the air flow inside the engine room of the vehicle has been introduced. However, in this case, it is difficult to finely control the temperature inside the engine room by adjusting the flow rate only at the engine room inlet, and in particular, when the under cover is installed, air is stagnated inside the engine room to make the flow rate more difficult to adjust.
본 발명은 전술한 바와 같은 문제점들을 해결하기 위해 창출된 것으로서, 본 발명이 해결하려는 과제는 자동차의 엔진 룸의 하부를 덮는 언더 커버에 공기 배출공을 형성함으로써 공기 배출에 따른 저항을 줄이면서도 공기를 효과적으로 배출할 수 있는 언더 커버 및 이를 포함하는 자동차를 제공하는 것이다.The present invention has been made to solve the problems described above, the problem to be solved by the present invention is to form an air outlet hole in the undercover covering the lower part of the engine room of the vehicle by reducing the air emissions while reducing the air It is to provide an undercover and an automobile including the same that can be effectively discharged.

이하에서 본 발명의 실시예를 첨부된 도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명의 실시예에 따른 자동차용 언더 커버(under cover)(100)는 자동차의 엔진 룸(engine room)의 하부를 덮는 기능을 한다. 비록 도 1에 언더 커버(100)의 형태가 예시적으로 도시되어 있으나, 언더 커버(100)의 형태나 크기는 자동차의 종류나 크기 등에 따라 다양하게 변경될 수 있다.An under cover 100 for a vehicle according to an embodiment of the present invention functions to cover a lower portion of an engine room of a vehicle. Although the shape of the undercover 100 is illustrated in FIG. 1 by way of example, the shape or size of the undercover 100 may be variously changed according to the type or size of a vehicle.
먼저, 도 1을 참조하면, 언더 커버(100)는 몸체(110)를 구비한다. 몸체(110)는 자동차의 엔진 룸의 하부에 장착될 수 있는 형태를 가지며, 예를 들어 플레이트 형태를 가질 수 있다. 예를 들어, 본 발명의 실시예에 따른 언더 커버(100)는, 도 5에 예시적으로 도시된 바와 같이, 자동차의 엔진 룸의 하부에 장착될 수 있다.First, referring to FIG. 1, the under cover 100 includes a body 110. Body 110 has a form that can be mounted on the lower portion of the engine room of the vehicle, for example may have a plate shape. For example, the under cover 100 according to the embodiment of the present invention may be mounted at the bottom of the engine room of the vehicle, as exemplarily shown in FIG. 5.
그리고 몸체(110)에는 공기 배출공(120)이 형성된다. 공기 배출공(120)은 자동차의 라디에이터 그릴 등을 통과하여 엔진 룸으로 유입된 공기가 다시 외부로 배출되는 통로로 작용하게 된다. 즉, 본 발명의 실시예에 따른 언더 커버(100)가 장착된 자동차에서는 라디에이터 그릴로 유입된 공기가 엔진 룸의 다양한 부품들 사이를 통과한 후 공기 배출공(120)을 통해서 외부로 배출된다.And the body 110, the air discharge hole 120 is formed. The air outlet hole 120 serves as a passage through which the air introduced into the engine room through the radiator grille of the vehicle is discharged to the outside again. That is, in the vehicle equipped with the under cover 100 according to the embodiment of the present invention, the air introduced into the radiator grill is discharged to the outside through the air discharge hole 120 after passing between the various parts of the engine room.
이때, 도 1 및 도 2를 참조하면, 공기 배출공(120)을 형성하는 면 중 자동차의 하부를 지나는 공기의 흐름의 방향을 따라 위치하는 두 면(121, 123) 중 어느 한 면은 공기 흐름의 방향을 따라 경사지게 형성된다. 즉, 도 1 및 도 2에 도시된 바와 같이, 공기 배출공(120)을 형성하는 면 중 공기 흐름 방향을 따라 위치하는 두 면(121, 123)이 공기 흐름 방향, 즉 자동차의 전후 방향에 대해 수직으로 형성되는 것이 아니라 경사지게 형성된다. 비록 도면에는 두 면(121, 123) 모두가 경사지게 형성되는 것으로 도시되어 있으나 두 면 중 어느 하나만 경사지게 형성될 수도 있다. 그리고 도면에는 공기 배출공(120)이 대략 사각형의 형태를 가지는 것으로 나타나 있으나 공기 배출공(120)은 필요에 따라 다양한 형태로 변경될 수 있으며, 예를 들어 공기 배출공(120)을 형성하는 면이 곡면을 포함하는 경우 공기의 흐름 방향을 따라 위치하는 면이 곡면 또는 곡면을 포함하는 면이 될 수도 있다.1 and 2, any one of two surfaces 121 and 123 positioned along the direction of the flow of air passing through the lower portion of the vehicle among the surfaces forming the air discharge hole 120 is an air flow. It is formed to be inclined along the direction of. That is, as illustrated in FIGS. 1 and 2, two surfaces 121 and 123 positioned along the air flow direction among the surfaces forming the air discharge holes 120 are provided in the air flow direction, that is, the front and rear directions of the vehicle. It is not formed vertically but inclined. Although both surfaces 121 and 123 are shown to be inclined in the drawing, only one of the two surfaces may be inclined. In addition, although the air discharge hole 120 is shown to have a substantially rectangular shape in the drawing, the air discharge hole 120 may be changed into various shapes as necessary, for example, a surface forming the air discharge hole 120. In the case of including the curved surface, a surface positioned along the air flow direction may be a curved surface or a surface including a curved surface.
이와 같이 공기 배출공(120)이 공기 흐름 방향에 대해 경사지게 형성됨으로써 공기 배출공(120)을 통해서 배출되는 공기가 외부 공기와 대략 나란한 방향으로 배출되게 되어 공기 흐름에 따른 저항이 감소하게 된다. 이에 따라 연비 향상 및 소음 저감의 효과를 얻을 수 있다.As such, the air discharge hole 120 is formed to be inclined with respect to the air flow direction, so that the air discharged through the air discharge hole 120 is discharged in a direction substantially parallel to the outside air, thereby reducing the resistance due to the air flow. Thereby, the effect of fuel efficiency improvement and noise reduction can be obtained.
한편, 도 3 및 도 4를 참조하면, 본 발명의 다른 실시예에 따른 자동차용 언더 커버는 공기 배출공(120)을 선택적으로 개폐할 수 있도록 형성되는 조절 플레이트(130)를 더 포함할 수 있다. 이때, 조절 플레이트(130)는 공기 배출공(120)의 일측에 슬라이딩(sliding) 가능한 상태로 설치될 수 있다.Meanwhile, referring to FIGS. 3 and 4, the under cover for a vehicle according to another embodiment of the present invention may further include an adjustment plate 130 formed to selectively open and close the air discharge hole 120. . At this time, the adjustment plate 130 may be installed in a state capable of sliding on one side of the air discharge hole (120).
예를 들어, 조절 플레이트(130)는 몸체(110)에 설치될 수 있으며, 공기 배출공(120)의 형상에 대응하는 형상을 가질 수 있다. 그리고 조절 플레이트(130)의 슬라이딩 구동을 위한 구동력을 제공하는 모터와 같은 액추에이터(actuator)(140)가 구비될 수 있으며, 액추에이터(140)의 구동축(141)에 조절 플레이트(130)가 기어 결합됨으로써 액추에이터(140)의 구동력에 의해 조절 플레이트(130)가 전후 방향으로 슬라이딩 되도록 할 수 있다. 구체적인 예를 들면, 액추에이터(140)의 구동축(141)에 기어(143)를 형성하고 이에 치합되는 기어(131)를 조절 플레이트(130) 상에 형성함으로써, 액추에이터(140)의 구동력에 의해 조절 플레이트(130)가 전후 방향으로 구동될 수 있다. 이러한 액추에이터(140)의 구동을 제어함으로써 조절 플레이트(130)의 위치를 제어할 수 있으며 이에 따라 공기 배출공(120)의 개방 정도를 임의로 조절할 수 있다. 조절 플레이트(130)가 도 4의 실선의 상태인 경우 공기 배출공(120)이 완전히 폐쇄되며 점선의 상태인 경우 공기 배출공(120)이 최대한 개방되며 실선과 점선의 중간 상태인 경우 공기 배출공(120)이 부분적으로 개방된다.For example, the adjusting plate 130 may be installed in the body 110 and may have a shape corresponding to the shape of the air discharge hole 120. And an actuator (actuator) 140, such as a motor that provides a driving force for the sliding drive of the adjustment plate 130 may be provided, the control plate 130 is coupled to the drive shaft 141 of the actuator 140 by gear coupling The adjustment plate 130 may be slid in the front-rear direction by the driving force of the actuator 140. For example, by forming a gear 143 on the drive shaft 141 of the actuator 140 and forming a gear 131 to be engaged with it on the adjusting plate 130, by the driving force of the actuator 140 130 may be driven in the front-rear direction. By controlling the driving of the actuator 140, the position of the adjustment plate 130 may be controlled, and thus the degree of opening of the air discharge hole 120 may be arbitrarily adjusted. When the control plate 130 is in the solid line state of FIG. 4, the air discharge hole 120 is completely closed, and in the case of the dotted line, the air discharge hole 120 is opened as much as possible. 120 is partially open.
이와 같이 공기 배출공(120)과 조절 플레이트(130)가 구비됨으로써, 공기 배출공(120)을 통한 공기 흐름에 의한 저항을 줄일 수 있을 뿐만 아니라 자동차 주행 시 엔진 룸을 냉각해야 할 상황에서는 조절 플레이트(130)가 공기 배출공(120)을 개방하도록 하여 효과적인 냉각이 이루어지도록 하고 반면 자동차의 시동 시 또는 초기 운행 시 등 엔진 룸의 온도의 상승이 필요한 경우에는 조절 플레이트(130)가 공기 배출공(120)을 폐쇄하도록 하여 엔진 룸의 온도가 상승되도록 할 수 있다.As such, since the air discharge hole 120 and the adjustment plate 130 are provided, not only can reduce the resistance due to the air flow through the air discharge hole 120, but also in the situation where the engine room must be cooled while driving a vehicle. When the air outlet hole 120 is opened to allow effective cooling, while the temperature rise of the engine room is required, such as when the vehicle is started or during initial operation, the control plate 130 is provided with an air outlet hole ( 120 may be closed to allow the temperature of the engine room to rise.
