Description

차량용 벤딩 라이트 시스템{Bending Light System for a Motor Vehicle}Bending Light System for a Motor Vehicle

본 발명은 차량용 벤딩 라이트 시스템에 관한 것으로, 보다 상세하게는 곡선도로 운행시 조향각에 따라 헤드램프의 조사각을 변화시켜 운전자가 차량을 진행시키고자 하는 방향의 전방에 조명이 비추어질 수 있도록 하는 벤딩 라이트 시스템에 관한 것이다.The present invention relates to a bending light system for a vehicle, and more particularly, a bending for changing the irradiation angle of a headlamp according to a steering angle when driving a curved road so that a light can shine in front of a direction in which a driver wants to advance a vehicle. Relates to a light system.

통상적으로 헤드램프는 램프 하우징에 고정되어 차량의 중심 라인과 일치하는 방향만을 조사한다. 따라서, 곡선도로를 진행하는 경우, 헤드램프는 차량의 현재 자세에서의 정방향만을 비추게 되므로, 운전자는 진행하고자 하는 방향의 도로 상황에 대한 정보를 얻지 못하는 문제가 있다.Typically the headlamps are fixed to the lamp housing and irradiate only the direction that coincides with the center line of the vehicle. Therefore, when the curved road proceeds, the headlamp only reflects the forward direction in the current posture of the vehicle, so that the driver cannot obtain information on the road situation in the direction to proceed.

따라서, 최근에는 이러한 문제를 해결하기 위하여 차량의 좌우 회전상태에 따라 조사각이 좌우 방향으로 자동 조절되는 벤딩 라이트를 헤드램프에 적용하는 비율이 높아지고 있다. 이와 관련된 기술을 적응 프론트 조명시스템(AFS: Adaptive Front-lighting System)이라고 하며, 참조될 수 있는 문헌으로는, KR 2002-0055423 A(2002.07.08), KR 2005-0023892 A(2005.03.10), KR 2005-0120364 A(2005.12.22), KR 2006-0055865 A(2006.05.24), KR 2007-0060756 A(2007.06.13), KR 2007-0045588 (2007.05.02)이 있다.Therefore, in recent years, in order to solve such a problem, the ratio of applying a bending light to the headlamp in which the irradiation angle is automatically adjusted in the left and right directions according to the left and right rotational states of the vehicle is increasing. The related technology is called the Adaptive Front-lighting System (AFS), and the literature which can be referred to is KR 2002-0055423 A (2002.07.08), KR 2005-0023892 A (2005.03.10), KR 2005-0120364 A (2005.12.22), KR 2006-0055865 A (2006.05.24), KR 2007-0060756 A (2007.06.13) and KR 2007-0045588 (2007.05.02).

도 1 내지 도 3을 참조하여 종래 벤딩 라이트의 문제점을 살펴본다.A problem of the conventional bending light will be described with reference to FIGS. 1 to 3.

도 1에는 벤딩 라이트(102)를 갖는 헤드램프(100)가 도시되어 있다. 통상적적으로, 벤딩 라이트(102)는, 헤드램프 하우징(101)에 축고정되어 액츄에이터(미도시)에 의해 좌우 방향으로 회동되거나, 반사경(미도시) 조절에 의해 좌우 방향 조사각이 변화될 수 있다. 헤드램프 하우징(101)의 바깥쪽에 설치된 미설명 부호 103은 터닝 램프이다.1 shows a headlamp 100 having a bending light 102. Typically, the bending light 102 is axially fixed to the headlamp housing 101 to be rotated left and right by an actuator (not shown), or the left and right irradiation angles may be changed by adjusting a reflector (not shown). have. Reference numeral 103 installed on the outside of the headlamp housing 101 is a turning lamp.

도 2에는 도 1에 도시된 바와 같은 종래 벤딩 라이트에 의한 배광패턴이 도시되어 있다. (a)는 직진시, (b)는 좌회전시, (c)는 우회전시의 배광패턴이 도시된 것이다.FIG. 2 illustrates a light distribution pattern by a conventional bending light as shown in FIG. 1. (a) is a straight line, (b) is a left turn, (c) is a right light distribution pattern is shown.

먼저, 도 2의 (a)를 살펴보면, 수평 방향으로 그어진 컷오프 라인(1) 아래에 벤딩 라이트의 조사영역이 형성된다. 여기서, 컷오프 라인(1)은 우측이 좌측 보다 높게 설정되어 있고, 그에 따라 배광패턴(2)의 우측 상부의 조사영역(2a)이 위로 치우쳐 있다. 이는 주행 차선인 우측 차로에 설치된 각종 도로 표지판을 운전자가 용이하게 인식할 수 있도록 하기 위한 것으로서, 이러한 컷오프 라인(1)은 국내와 유럽 등에서 채택되고 있다.First, referring to FIG. 2A, the irradiation area of the bending light is formed under the cutoff line 1 drawn in the horizontal direction. Here, the cutoff line 1 has the right side set higher than the left side, and thus the irradiation area 2a of the upper right side of the light distribution pattern 2 is biased upward. This is to allow the driver to easily recognize various road signs installed on the right lane, which is the driving lane, and the cutoff line 1 is adopted in Korea and Europe.

그러나, 위와 같은 컷오프 라인(1)은, 우회전시에는 문제가 없으나, 좌회전시 다음과 같은 문제가 나타난다. 즉, 도 2의 (b)에서 볼 수 있듯이, 벤딩 라이트의 좌향에 따라 우측 상부의 조사영역(2a)이 함께 좌측으로 이동되어, 반대편 차로의 컷오프 라인을 침범하게 되는 것이다. 이는 반대편 차로를 진행하는 차량의 운 전자에게 눈부심을 일으키게 되는 것이어서, 금지된다. 따라서 법규를 충족시키기 위하여, 현재 차량 메이커에서는 차량 좌회전시 벤딩 라이트를 좌향시킴과 아울러, 도 3에서 보듯이, 벤딩 라이트의 배광패턴 중 우측 상부의 조사영역(2a)을 컷오프 라인 아래로 하향시키기 위한 별도의 구동장치 혹은 메커니즘을 마련하고 있다.However, the above cutoff line 1 has no problem in the right turn, but the following problem occurs in the left turn. That is, as shown in (b) of FIG. 2, the irradiation area 2a on the upper right side moves together with the left side of the bending light to the left to invade the cutoff line to the opposite side. This will cause glare to the driver of the vehicle driving on the other side of the lane and is prohibited. Therefore, in order to satisfy the law, the current vehicle manufacturer turns the bending light to the left when the vehicle is turned left, and as shown in FIG. A separate drive or mechanism is provided.

본 발명은 위와 같은 문제점을 해결하기 위하여 제안된 것으로, 차량 좌회전시 벤딩 라이트의 조사각을 별도로 하향시키기 위한 별도의 메커니즘을 필요로 하지 않는, 간단한 구조의 벤딩 라이트 시스템을 제공하고자 한다.The present invention has been proposed to solve the above problems, and does not require a separate mechanism for separately lowering the irradiation angle of the bending light when the vehicle turns left, to provide a simple bending light system.

상기의 목적을 달성하기 위한 본 발명에 따른 차량용 벤딩 라이트 시스템은, 헤드램프 하우징에 고정되어 일정 조사각을 갖는 고정램프와, 이 고정램프의 바깥쪽에 배열되며, 좌우방향으로의 조사각은 변화될 수 있고, 상방향 조사각은 일정하되 고정램프 보다 낮게 조절되는 하나 이상의 가동램프를 구비한다. 여기서, 차량의 조향각에 따라 가동램프들을 좌우방향 조사각을 동시에 변화시키는 것은 별도의 조사각 조절유닛에 의해 이루어진다.The vehicle bending light system according to the present invention for achieving the above object is a fixed lamp having a fixed irradiation angle fixed to the headlamp housing, and arranged outside the fixed lamp, the irradiation angle in the left and right directions can be changed And the upward irradiation angle is constant but has one or more movable lamps which are adjusted lower than the stationary lamps. Here, simultaneously changing the irradiation angle of the movable lamps in the left and right directions according to the steering angle of the vehicle is made by a separate irradiation angle adjusting unit.

상기 가동램프들의 좌우방향 조사각 변화는 서로 상이하게 조절되는 것이 바람직하며, 더욱 바람직하게는, 가동램프들 중 가장 바깥쪽 램프가 조사각 변화가 가장 크며 안쪽으로 갈수록 점차 작아진다.It is preferable that the left and right irradiation angle changes of the movable lamps are adjusted differently from each other, and more preferably, the outermost lamp among the movable lamps has the largest irradiation angle change and gradually decreases toward the inside.

또한, 상기 가동램프들은, 각각의 회동축을 중심으로 좌우방향 회동될 수 있 도록 헤드램프 하우징에 설치되며, 조사각 조절유닛이 가동램프들을 동시에 회동시켜 좌우방향 조사각을 변화시키는 것이 바람직하다. 물론, 램프 자체를 회동시키기 않고, 반사경을 이용하여 가동램프들 조사각을 변화시킬 수도 있을 것이다. In addition, the movable lamps are installed in the head lamp housing so as to be able to rotate left and right about each rotating shaft, and it is preferable that the irradiation angle adjusting unit rotates the movable lamps at the same time to change the left and right irradiation angles. Of course, it is also possible to change the irradiation angles of the movable lamps using a reflector without rotating the lamp itself.

상술한 바와 같은 구조로 이루어진 차량용 벤딩 라이트 시스템은, 차량 좌회전시 벤딩 라이트의 조사각을 별도로 하향시키기 위한 별도의 메커니즘을 필요로 하지 않으며, 구조가 간단하다.The vehicle bending light system having the structure as described above does not require a separate mechanism for separately lowering the irradiation angle of the bending light when the vehicle turns left, and the structure is simple.

이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 따른 차량용 벤딩 라이트 시스템에 대하여 살펴본다.Hereinafter, a vehicle bending light system according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

도 4에는 일실시예에 따른 벤딩 라이트 시스템이 적용된 헤드램프(100)가 도시되어 있다.4 shows a headlamp 100 to which a bending light system is applied according to an embodiment.

도 4에서 보듯이, 일실시예에 따른 벤딩 라이트 시스템은 헤드램프 하우징(101) 내에 좌우방향으로 일렬 배열된 하나 이상의 램프(10,20,30,40,50)를 포함한다. 여기서, 가장 안쪽의 램프는 고정램프(50)이며, 이 램프의 바깥쪽에 배열된 램프들은 가동램프(10,20,30,40)이다. 터닝 램프(103)가 배치되는 쪽이 바깥쪽 방향이다.As shown in FIG. 4, the bending light system according to an embodiment includes one or more lamps 10, 20, 30, 40, and 50 arranged in a left and right direction in the headlamp housing 101. Here, the innermost lamp is a fixed lamp 50, and the lamps arranged outside the lamps are movable lamps 10, 20, 30, and 40. The side where the turning lamp 103 is disposed is the outward direction.

도 5 내지 도 7을 참조하여, 벤딩 라이트 시스템의 구체적인 구성을 살펴본다.5 to 7, a detailed configuration of the bending light system will be described.

도 5는 차량이 직진 주행하는 경우의 벤딩 라이트 시스템의 상태를 도시한 도면이다. 도 5에서 볼 수 있는 바와 같이, 벤딩라이트 시스템은, 1개의 고정램프(50)과, 4개의 가동램프(10,20,30,40), 가동램프들을 좌우방향으로 회동시키기 위한 조사각 조절유닛으로 구성된다.5 is a diagram illustrating a state of the bending light system when the vehicle travels straight. As can be seen in Figure 5, the bending light system, one fixed lamp 50, four movable lamps (10, 20, 30, 40), the irradiation angle adjusting unit for rotating the movable lamps in left and right directions It consists of.

고정램프(50)는, 헤드램프 하우징(101)의 가장 안쪽에 고정설치되며, 좌우방향으로 회동되지 않고 일정한 조사각을 갖는다.The fixed lamp 50 is fixedly installed at the innermost side of the head lamp housing 101 and has a constant irradiation angle without being rotated in the left and right directions.

가동램프들(10,20,30,40)은, 고정램프(50)의 바깥쪽에 배열되며, 각각의 회동축(12,22,32,42)을 구비하여 각각 좌우방향 회동 가능하다. 다만, 이들 가동램프들은 완전히 독립적으로 회동되는 것은 아니며, 바깥쪽 램프(10)의 회동량이 가장 크고 안쪽으로 갈수록 점차 작아지도록 조절된다. 가동램프들(10,20,30,40)의 각 회동축 후방에는 회동바(11,21,31,41)가 연장 형성되어 있고, 이 회동바에 연결된 조사각 조절유닛(60,70)에 의해 가동램프들이 회동된다.The movable lamps 10, 20, 30, and 40 are arranged on the outside of the fixed lamp 50 and have respective rotating shafts 12, 22, 32, and 42, respectively, and are rotatable in left and right directions. However, these movable lamps are not rotated completely independently, and the amount of rotation of the outer lamp 10 is adjusted to be the largest and gradually smaller toward the inside. Rotating bars 11, 21, 31, and 41 are formed at the rear of each rotating shaft of the movable lamps 10, 20, 30, and 40, and are provided by the irradiation angle adjusting units 60 and 70 connected to the rotating bars. The movable lamps are rotated.

조사각 조절유닛(60,70)은 링크(60)와 액츄에이터(70)로 구성되는 바, 도 5 내지 도 8을 참조하여 설명한다.Irradiation angle adjusting unit (60, 70) is composed of a link 60 and the actuator 70, will be described with reference to FIGS.

링크(60)는, 가동램프들(10,20,30,40) 중 어느 하나가 회동되면 다른 램프들도 연동하여 회동될 수 있도록 회동바들(11,21,31,41)을 2개씩 짝지어 순차 연결하는 부재로서, 제1링크(61)는 제1램프(10)와 제2램프(20)를 연결하고, 제2링크(62)는 제2램프(20)와 제3램프(30)를 연결하고, 제3링크(63)는 제3램프(30)와 제4램프(40)를 연결한다. 도 8에서 보듯이, 가장 안쪽 램프(40)을 제외한 다른 램프들의 회동축(12,22,32)과, 이들 램프들(10,20,30)을 서로 연결하는 각 링크의 바깥쪽 연결점(61a,62a,63a)까지의 거리는 제1램프(10)로부터 제3램프(30)의 방향으로 점차 가까워지도록 설정된다. 각 링크의 안쪽 연결점(61b,62b,63b)과 각 회동축(12,22,32)까지의 거리는 동일하게 설정된다. 이러한 링크 연결구조에 따라, 가동램프들(10,20,30,40)의 좌우방향 회동각이 바깥쪽 램프가 가장 크고 안쪽으로 갈수록 점차 작아지게 된다. 각 링크의 바깥쪽 연결점(61a, 62a, 63a)과 제3링크(63)의 안쪽 연결점(63b)는 각 회동바에 힘이 작용되는 지점인 바, 작용점이라 지칭하도록 한다.The link 60 pairs two rotation bars 11, 21, 31, and 41 so that when one of the movable lamps 10, 20, 30, and 40 is rotated, the other lamps may be rotated in conjunction with each other. As a member for sequentially connecting, the first link 61 connects the first lamp 10 and the second lamp 20, and the second link 62 is the second lamp 20 and the third lamp 30. The third link 63 connects the third lamp 30 and the fourth lamp 40. As shown in FIG. 8, the outer connecting points 61a of the rotational shafts 12, 22, 32 of the other lamps except the innermost lamp 40 and each link connecting these lamps 10, 20, 30 to each other. The distances to 62a and 63a are set to be gradually closer to the direction of the third lamp 30 from the first lamp 10. The distances between the inner connection points 61b, 62b and 63b of each link and the respective pivot shafts 12, 22 and 32 are set equal. According to this link connection structure, the left and right rotation angles of the movable lamps 10, 20, 30, and 40 become the largest outer lamp and gradually decrease toward the inner side. The outer connection points 61a, 62a, 63a of each link and the inner connection point 63b of the third link 63 are bar points at which a force is applied to each pivot bar, so that they are referred to as operating points.
