상세하게는 전조등의 반사판을 조사범위를 좁게 또는 넓게 할 수 있도록 가변되게 구성하여 광량을 조절하도록 하는 자동차용 전조등의 반사판 조사각 조절장치에 관한 것이다.In particular, the present invention relates to a reflector plate angle control device for a headlamp for automobiles configured to vary the amount of light by varying the reflector plate of the headlamp so as to narrow or widen the irradiation range.
일반적으로, 전조등은 렌즈와 반사판, 전구(또는 필라멘트)로 구성되고, 형식에 따라 시일드 빔 형식(Scalcd Bcam Type)과 세미 시일드 빔 형식(Semi Scalcd Bcam Type)으로 대별된다.In general, headlights are composed of a lens, a reflector, and a bulb (or filament), and are classified into a shielded beam type (Scalcd Bcam Type) and a semi shielded beam type (Semi Scalcd Bcam Type) according to the type.
먼저, 시일드 빔 형식은 반사판에 필라멘트를 붙이고 여기에 렌지를 녹여 붙인후 그 내부에 불활성 가스를 넣어 전조등 자체가 하나의 전구가 되게 하는 형식이고, 세미 시일드 빔 형식은 렌즈와 반사경은 융착하였으나 전구는 별개로 설치하는 형식으로 필라멘트가 절단되면 전구만 교환할 수 있게 구성되어 있는 형식이다.First, the sealed beam type is a type in which a filament is attached to a reflector and a stove is melted, and then an inert gas is put therein so that the headlamp itself becomes a single light bulb. The bulbs are installed separately and can only be replaced when the filament is cut.
그러나, 이와같은 종래의 전조등은 반사판이 고정설치되기 때문에 반사판을 통한 광도가 항상 일정하여 일정거리 이상에서의 물체를 판별할 수 없었다.However, such a conventional headlamp is fixed because the reflector is fixed, the brightness through the reflector is always constant, it was not possible to determine the object at a certain distance or more.
따라서, 본 발명은 상기와 같은 제반 문제를 해결하기 위해 안출된 것으로서, 그 목적은 전조등의 반사판을 조사범위를 좁게 또는 넓게 할 수 있도록 가변되게 구성하여 광량을 조절하도록 하는 자동차용 전조등의 반사판 조사각 조절장치를 제공함에 있다.Accordingly, the present invention has been made to solve the above-mentioned problems, the object of the reflecting plate irradiation angle of the headlamps for automobiles to adjust the amount of light by varying the reflector of the headlamps to narrow or wide the irradiation range In providing an adjusting device.
상기 목적을 달성하기 위해 본 발명은 일정 회동범위에서 정/역 회동하는 구동수단;The present invention to achieve the above object is a drive means for forward / reverse rotation in a certain range of rotation;
상기 구동수단과 축결합되어 구동력을 전달하도록 하는 구동전달수단,Drive transmission means for axially coupled with the drive means for transmitting a drive force,
상기 구동전달수단과 슬라이딩 축결합되어 서로 대칭변위되게 가동하는 가동수단;Movable means coupled to the drive transmission means and axially displaced to each other;
상기 가동수단에 의해 수평 또는 수직 각도가 변위되는 반사판으로 구성하여된 특징을 갖는다.It is characterized by consisting of a reflector plate which the horizontal or vertical angle is displaced by the movable means.
이하, 본 발명을 첨부한 도면에 의거하여 보다 상세하게 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail based on attached drawing.
제1도는 본 발명에 따른 자동차용 전조등의 반사판 조사각 조절장치를 도시한 측단면도이고, 제2도는 본발명의 사용상태도로서,1 is a side cross-sectional view showing a reflecting plate irradiation angle adjusting device of a headlamp for an automobile according to the present invention, and FIG. 2 is a use state diagram of the present invention.
전원부(도시않됨)와 전기적으로 연결되고, 일정 회동범위에서 정/역 회동하는 구동수단(10)과,A driving means 10 electrically connected to a power supply unit (not shown) and forward / reversely rotated in a predetermined rotation range;
상기 구동수단(10)과 축결합되어 연결하면서 구도수단(10)의 구동력을 전달하도록 하는 구동전달수단(20)과,A drive transmission means 20 which is axially coupled with the drive means 10 to transmit a driving force of the composition means 10;
상기 구동전달수단(20)과 슬라이딩 축 결합되어 서로 대칭 변위되게 가동하는 가동수단(30)과,A movable shaft 30 coupled to the driving transmission means 20 and movable to be symmetrically displaced with each other;
상기 가동수단(30)에 의해 수평 또는 수직각도가 변위되는 반사판(40)으로 구성하여 된 것이다.The movable means 30 is composed of a reflecting plate 40 which is displaced horizontally or vertically.
한편, 구동수단(10)은 스텝모터(12)로 구성하여 된 것이다.On the other hand, the drive means 10 is composed of a step motor 12.
한편, 구동전달수단(20)은 스텝모터(12)축에 압입된 주동기어(23), 상기 주동기어(23)와 동일 수평축 방향으로 서로 치합된 종등기어(24), 상기 종동기어(24)의 중심에 압입되되, 그 외주면에 서로 다른 방향의 나사부(25)가 대칭 형성된 회동축(26)으로 구성하여 된 것이다.On the other hand, the drive transmission means 20 is the main gear 23 pressed into the step motor 12 shaft, the same gear 24 and the driven gear 24 meshed with each other in the same horizontal axis direction as the main gear 23 It is press-fitted to the center of the, but the outer periphery of the screw portion 25 in a different direction is composed of a rotating shaft 26 formed symmetrically.
또한, 가동수단(30)은 종동기어(24)에 압입된 회동축(26)의 양 나사부(25)에 의해 대칭 이동되게 볼 스크류 결합된 다수의 가동구(32)(34)로 구성하여 된 것이다.In addition, the movable means 30 is composed of a plurality of movable holes 32, 34 which are ball screwed so as to be symmetrically moved by both threads 25 of the rotating shaft 26 pressed into the driven gear 24. will be.
또한, 상기 각 가동구(32)(34)의 외향측단에 길이방향의 가압편(32a)(34a)이 각각 형성되는데, 그 이유는 회동축(26)의 나사부(25)를 따라 수평 또는 수직이동하면서 반사판(40)의 각도를 변위시키게 하기 위함이다.In addition, the pressing pieces 32a and 34a in the longitudinal direction are formed at the outward side ends of the movable ports 32 and 34, respectively, for the reason of horizontal or vertical along the threaded portion 25 of the pivot shaft 26. This is to displace the angle of the reflector 40 while moving.
상기와 같이 구성된 본 발명의 작용 및 효과를 설명한다.The operation and effects of the present invention configured as described above will be described.
전원부에 의해 스텝모터(12)로 전기가 인가되면 회동과 아울러 그 축에 압입된 주동기어(23)를 회동시킨다.When electricity is applied to the stepper motor 12 by the power supply unit, the main gear 23 pushed into the shaft is rotated as well as rotating.
상기 주동기어(23)와 치합된 종동기어(24)는 연동되면서 압입된 회동축(26)을 회동시키는데, 상기 회동축(26)의 각 나사부(25)에 각각 위치된 가동구(32)(34)는 서로 반대방향의 나사부(25)에 의해 대칭되게 좁혀지거나 넓혀진다.The driven gear 23 meshed with the main gear 23 rotates the pivot shaft 26 that is press-fitted while being interlocked, and includes a movable hole 32 positioned at each threaded portion 25 of the pivot shaft 26 ( 34 is symmetrically narrowed or widened by threads 25 in opposite directions.
상기 각 가동구(32)(34)의 외향 측단에 길이방향으로 형성된 가압편(32a)(34a)에 의해 반사판(40)이 좁혀지거나 넓혀져 전구(42)의 광도를 조절할 수 있게 되는 것이다.The reflecting plate 40 is narrowed or widened by the pressing pieces 32a and 34a formed in the longitudinal direction at the outward side ends of the movable holes 32 and 34 so that the brightness of the bulb 42 can be adjusted.
따라서, 이와같은 본 발명을 실차에 적용하게 되면, 임의로 전조등의 광도를 조절할 수 있게 되어 같은 광원으로 범위는 그리 넓지는 않지만 먼거리를 조사하므로서 야간시 갑자기 나타나는 물체를 보다 빨리 판별할 수 있게 되어 발생될 수 있는 사고를 미연에 방지되는 효과가 있다.Therefore, when the present invention is applied to a real vehicle, it is possible to arbitrarily adjust the brightness of the headlamp, so that the range of the same light source is not very wide, but it is possible to identify objects that appear suddenly at night by irradiating a long distance. There is an effect that can prevent accidents in advance.
