본 발명은 자동차의 헤드램프 상하향 자동조정장치에 관한 것으로, 더욱 상세하게는 야간 주행시 헤드램프의 상향등을 작동시킨 상태에서 주행하다가 전방으로부터 마주오는 차량의 헤드램프 불빛을 감지하게 되면 자동으로 하향등으로 전환되는 자동차의 헤드램프 상하향 자동조정장치에 관한 것이다.The present invention relates to a device for automatically adjusting the headlamp up and down of a vehicle, and more particularly, when the headlamp light of the vehicle coming from the front is detected while driving while the headlamp is turned on at night, the lamp is automatically turned down. The present invention relates to an automatic adjustment device for up and down headlamps of a vehicle to be switched.
자동차에는 어두운 곳이나 야간에 주행하게 될 때 전방을 밝게 비쳐주어 운전자의 시야를 확보해 줄 수 있도록 된 헤드램프으로서 헤드램프가 설치되어 있는 바, 주로 운전자가 조작하기 용이한 위치의 조향축에 설치되는 컴비네이션스위치(여기서 컴비네이션스위치라 함은 조명에 관된 라이트스위치를 말함)를 운전자가 조작함에 따라 점등 또는 소등되도록 설치되어 있다.The car is a headlamp that provides a clear view of the driver when driving in a dark place or at night to secure the driver's vision. The headlamp is installed in a steering shaft that is easily accessible to the driver. The combination switch (here, the combination switch refers to a light switch related to lighting) is installed to be turned on or off as the driver operates.
또한 헤드램프는 주로 근거리를 조사하도록 된 하향등과 원거리까지 조사할 수 있는 상향등으로 구성되어 있는데, 상향등은 원거리까지 조사하기 위하여 조사각도가 수직방향으로 넓게 퍼지도록 이루어져 있다.In addition, the headlamp mainly consists of a low-light to be irradiated at a short distance and a high-light can be irradiated to a long distance, the upper light is composed so that the irradiation angle is wide spread in the vertical direction to irradiate far.
그런데 헤드램프를 작동시킨 상태에서 야간에 운전을 하다가 차량이 교차로등에서 신호대기로 정차를 할 경우 또는 횡단보도등에서 보행자신호의 점등에 의해 일정시간 동안 정차를 하고 있게 될 경우 마주 보고 서있거나 주행하고 있는 상대 차량이나 동일 진행방향의 앞차에 눈부심을 주지 않기 위하여 또는 횡단보도를 보행하고 있는 보행자에게 눈부심을 주어 보행에 불편을 주지 않도록 하기 위한 등의 이유로 헤드램프를 소등시키고 있게 된다.However, when driving at night with the headlamp activated, the vehicle stops with a signal stand at an intersection, or when the vehicle stops for a certain period of time by turning on a pedestrian signal at a pedestrian crossing. The headlamps are turned off for the purpose of not giving a glare to an opponent vehicle or a vehicle in the same traveling direction, or to give a pedestrian walking on a crosswalk so as not to cause inconvenience to walking.
또한 주행중에 마주오는 차량이 없는 경우 상향등을 점등시켜 원거리까지 시야를 확보하면서 주행하다가 마주오는 차를 발견하게 되면 다시 하향등으로 바꾸어 주행하므로써 마주오는 차량의 운전자에 대한 시야확보에 지장을 주지 않으려고 하고 있다.In addition, if there is no vehicle coming while driving, the driver lights up the high beam to secure the view to a long distance, and when it finds an oncoming car, it switches to the low beam so that it does not interfere with securing the visibility of the driver of the oncoming vehicle. Doing.
그러나 종래의 자동차에 있어서는 헤드램프의 상하향등의 점등 및 소등은 운전자의 컴비네이션스위치 조작에 따라 이루어지도록 되어 있었기 때문에 주행도중에 일일이 운전자가 컴비네이션스위치를 조작하여 상향등에서 하향등으로 그리고 다시 하향등에서 상향등으로 변환시키게 되는 동작을 반복하게 되면 운전자가 매우 불편함을 느끼게 될 뿐만 아니라 경우에 따라서는 마주오는 차량이 있는데도 불구하고 상향등을 켠채 그대로 주행하게 되면 상대방 차량의 운전자에게 불쾌감을 주게 될 뿐만 아니라 안전운전에도 지장을 주게 되는 문제점이 발생된다.However, in the conventional vehicle, the headlights are turned on and off by the driver's combination switch operation. Therefore, the driver switches the combination switch from the high beam to the low beam and the low beam to the high beam again. If you repeat the action to make the driver feels very uncomfortable, in some cases, even if there is an oncoming vehicle, driving with the high beams turned on will not only cause discomfort to the driver of the other vehicle but also interfere with safe driving. Problems that arise.
본 발명은 상기한 문제점을 개선하기 위하여 안출된 것으로, 야간 운전시 운전자가 상향등을 점등시킨 상태로 주행하다가 마주오는 차량의 헤드램프로부터 발산되는 불빛을 감지하게 되면 자동으로 하향등으로 변환될 뿐만 아니라 마주오는 차량의 헤드램프로부터 발산되는 불빛이 사라지면 다시 상향등이 점등되는 동작이 자동으로 반복되도록 이루어진 자동차의 헤드램프 상하향 자동조정장치를 제공하고자 함에 발명의 목적이 있다.The present invention has been made in order to improve the above problems, when the driver while driving at night while the driving lights are turned on when the lights emitted from the headlamps of the oncoming vehicle is automatically converted to the downlight as well An object of the present invention is to provide a device for automatically adjusting the headlamp up and down of a vehicle which is configured to automatically repeat the operation of turning on the upper light again when the light emitted from the headlamp of the oncoming vehicle disappears.
상기한 목적을 실현하기 위한 본 발명은 컴비네이션스위치의 선택단자에 주행빔선택단자와 변환빔선택단자를 구비하고, 변환빔선택단자에는 광센서를 매개로 릴레이의 구동코일을 연결하는 한편 상기 릴레이의 가동스위치의 출력단자에는 헤드램프벌브의 주행빔단자와 변환빔단자를 연결하므로써, 컴비네이션스위치를 주행빔선택단자에 위치시켰을 때에는 일반적인 경우와 마찬가지로 하향등만 점등되도록 하고, 컴비네이션스위치를 변환빔선택단자에 위치시켰을 때에는 광센서의 감지상태에 따라 상기 릴레이의 가동스위치가 헤드램프벌브의 주행빔단자와 변환빔단자에 선택적으로 접속되도록 이루어져 있는 것이다.The present invention for realizing the above object is provided with a traveling beam selection terminal and a conversion beam selection terminal in the selection terminal of the combination switch, the conversion beam selection terminal is connected to the drive coil of the relay via an optical sensor, By connecting the travel beam terminal of the headlamp bulb and the conversion beam terminal to the output terminal of the movable switch, when the combination switch is placed on the travel beam selection terminal, only the downlight is turned on as in the normal case, and the combination switch is set to the conversion beam selection terminal. When the position is set to, the movable switch of the relay is selectively connected to the traveling beam terminal and the conversion beam terminal of the head lamp bulb according to the detection state of the optical sensor.
이하 본 발명의 구성 및 작용효과에 대하여 예시도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.
본 발명은 자동차배터리(10)가 연결되어 있는 컴비네이션스위치(12)의 선택단자에 주행빔선택단자(12b)와 변환빔선택단자(12c)를 구비하고, 상기 주행빔선택단자(12b)에는 헤드램프벌브(14)의 하향등단자(14b)를 연결하고, 변환빔선택단자(12c)에는 광센서(16)를 매개로 릴레이(18)의 구동코일(18a)을 연결함과 더불어 상기 릴레이(18)의 가동스위치의 공통단자(18b)를 연결하며, 상기 릴레이(18)의 가동스위치의 출력단자(18c)(18d)에는 헤드램프벌브(14)의 주행빔단자(14b)와 변환빔단자(14c)를 각각 연결한 구조로 되어 있다.The present invention includes a driving beam selection terminal 12b and a conversion beam selection terminal 12c at a selection terminal of the combination switch 12 to which the vehicle battery 10 is connected, and the driving beam selection terminal 12b has a head. The downlight terminal 14b of the lamp bulb 14 is connected, and the driving coil 18a of the relay 18 is connected to the conversion beam selection terminal 12c via an optical sensor 16, and the relay ( The common terminal 18b of the movable switch of 18 is connected, and the traveling beam terminal 14b and the conversion beam terminal of the head lamp bulb 14 are connected to the output terminals 18c and 18d of the movable switch of the relay 18. Each of the structures 14c is connected.
제1도는 종래의 자동차 헤드램프벌브에 있어 컴비네이션스위치의 조작에 따라 상향등과 하향등이 점등됨을 설명하기 위한 도면이다.FIG. 1 is a diagram for explaining that up and down lights are turned on according to a manipulation of a combination switch in a conventional head lamp bulb of a vehicle.
여기서 도면중 첨부된 부호는 제2도에 도시된 본 발명의 구성도에서 동일한 기능을 나타내는 구성요소와 동일한 부호가 부여된 것이다.In the drawings, the same reference numerals are given to the same elements as the same elements in the structural diagram of the present invention shown in FIG.
헤드램프벌브(14)는 상향등용 필라멘트(L1)와 하향등용 필라멘트(L2)로 각각 이루어져 있고, 2개의 헤드램프벌브(14)가 도시된 것은 좌측 헤드램프와 우측 헤드램프를 나타내는 것이다.The headlamp bulb 14 is composed of an uplight filament L1 and a downlight filament L2, and two headlamp bulbs 14 are shown to represent a left headlamp and a right headlamp.
또한 헤드램프벌브(14)와 연결되는 각 접속점(14a,14b,14c)은 본 발명을 나타내는 제2도에서의 헤드램프벌브(14)의 각 단자(14a,14b,14c)와 대응되는 것이다.Further, each connection point 14a, 14b, 14c connected to the headlamp bulb 14 corresponds to each terminal 14a, 14b, 14c of the headlamp bulb 14 in FIG.
이와 같은 구조에서는 운전자가 컴비네이션스위치(12)를 선택적으로 조작하여 헤드램프벌브(14)의 상향등용 필라멘트(L1)나 하향등용 필라멘트(L2)측과 접속시키면 자동차배터리(10)의 전원이 해당 필라멘트에 인가되어 점등된다.In such a structure, when the driver selectively operates the combination switch 12 and connects the headlamp bulb 14 to the uplight filament L1 or the downlight filament L2, the power of the vehicle battery 10 is applied to the filament. Applied to and lights up.
즉 상향등이나 하향등을 점등시키려면 운전자가 일일이 컴비네이션스위치(12)를 조작하여 해당 기능을 선택하여야 하고, 선택된 기능에서 다른 기능으로 변환시에도 운전자가 또다시 컴비네이션스위치(12)를 조작하여야 하므로 야간운전시 매우 번거로움을 느끼게 된다.That is, in order to turn on the high beam or the low beam, the driver must select the corresponding function by operating the combination switch 12 one by one, and the driver must operate the combination switch 12 again when switching from the selected function to another function. Poetry is very cumbersome.
제2도는 본 발명에 따른 헤드램프의 구동회로도를 도시한 것이다.2 shows a driving circuit diagram of a head lamp according to the present invention.
여기서 광센서(16)는 예컨대 제3도에 도시된 바와 같은 광전도셀을 이용한 것으로, 제3a도는 그의 평면도이고, 제3b도는 그의 단면도를 나타내는 것이다.Here, the optical sensor 16 uses, for example, a photoconductive cell as shown in FIG. 3, FIG. 3A is a plan view thereof, and FIG. 3B is a cross sectional view thereof.
도면중 31은 광도전막을 나타내는 것이고, 32a와 32b는 각각 전극을 나타내는 것으로서, 전극(32a,32b)간에 전압을 걸어두면 빛의 변화에 따라 두전극(32a,32b)간에 흐르는 전류량이 변하게 되고 이로부터 상대방 차량의 전조등 불빛을 감지하도록 된 것이다.In the figure, 31 represents a photoconductive film, and 32a and 32b represent electrodes, respectively, and when a voltage is applied between the electrodes 32a and 32b, the amount of current flowing between the two electrodes 32a and 32b changes according to the change of light. To detect the headlights of the other vehicle.
다시 제2도에 의거 본 발명의 작용에 대해 설명한다.The operation of the present invention will be described again with reference to FIG.
먼저 정상적인 주행빔작동상태 즉 하향등만을 점등시킨 상태로 주행할 때의 작용에 대해 설명한다.First, a description will be given of the operation when driving in the normal driving beam operating state, that is, only the downlight is turned on.
이때는 컴비네이션스위치(12)의 선택단자를 주행빔선택단자(12b)로 접속시킨다. 이에 따라 자동차배터리(10)의 전원이 주행빔선택단자(12b)를 통해 헤드램프벌브(14)의 주행빔단자(14b)로 인가되므로 하향등만 점등되어진다.At this time, the selection terminal of the combination switch 12 is connected to the travel beam selection terminal 12b. Accordingly, since the power of the vehicle battery 10 is applied to the travel beam terminal 14b of the headlamp bulb 14 through the travel beam selection terminal 12b, only the downlight is turned on.
다음에는 변환빔작동상태 즉 마주오는 차량의 유무에 따라 하향등과 상향등이 자동으로 선택 점등되어지는 동작에 대해 설명한다.Next, a description will be given of an operation in which the down light and the up light are automatically selected and turned on according to the conversion beam operation state, that is, whether there is an oncoming vehicle.
이때는 컴비네이션스위치(12)의 선택단자를 변환빔선택단자(12c)로 접속시킨다. 이에 따라 자동차배터리(10)의 전원이 릴레이(18) 가동스위치의 공통단자(18b)에 인가됨과 더불어 광센서(16)를 매개로 상기 릴레이(18)의 구동코일(18a)에 인가된다.At this time, the selection terminal of the combination switch 12 is connected to the conversion beam selection terminal 12c. Accordingly, the power supply of the vehicle battery 10 is applied to the common terminal 18b of the relay 18 movable switch and is applied to the driving coil 18a of the relay 18 via the optical sensor 16.
이와 같은 상태에서 만일 마주오는 차량의 전조등에 의한 불빛이 감지되지 않으면 광센서(16)에 의해 릴레이(18)의 구동코일(18a)로 인가되는 전류가 차단되므로 릴레이(18)가 작동되지 않는다.In such a state, if the light by the headlight of the oncoming vehicle is not detected, the relay 18 is not operated because the current applied to the driving coil 18a of the relay 18 is cut off by the optical sensor 16.
따라서 릴레이(18)의 가동스위치는 상시 접속접점인 출력단자(18d)에 접속된 상태로 머물러 있게 되므로써 릴레이(18) 가동스위치의 공통단자(18b)에 인가되어 있던 자동차배터리(10)의 전원은 출력단자(18d)를 통하여 변환빔단자(14c)로 인가된다. 그리하여 헤드램프의 상향등이 점등된다.Therefore, since the movable switch of the relay 18 remains connected to the output terminal 18d which is a normally connected contact, the power supply of the vehicle battery 10 applied to the common terminal 18b of the movable switch of the relay 18 is It is applied to the conversion beam terminal 14c through the output terminal 18d. Thus the headlights are turned on.
그러나 이와는 달리 마주오는 차량의 전조등에 의한 불빛이 감지되면 광센서(16)에서는 전류가 흐르게 되고, 그에 따라 컴비네이션스위치(12)의 변환빔선택단자(12c)에 인가되는 자동차배터리(10)의 전원은 광센서(16)를 통해 릴레이(18)의 구동코일(18a)로 인가되어 구동코일(18a)이 여자되므로 그의 가동스위치가 상시개방단자인 출력단자(18c)로 접속된다.On the other hand, when the light from the headlight of the oncoming vehicle is detected, the current flows through the optical sensor 16, and accordingly, the power of the vehicle battery 10 applied to the conversion beam selection terminal 12c of the combination switch 12. Is applied to the drive coil 18a of the relay 18 through the photosensor 16, and the drive coil 18a is excited, so that its movable switch is connected to the output terminal 18c which is a normally open terminal.
따라서 릴레이(18) 가동스위치의 공통단자(18b)에 인가되어 있던 자동차배터리(10)의 전원은 출력단자(18c)를 통하여 주행빔단자(14b)로 인가된다. 그리하여 헤드램프는 상향등에서 하향등으로 변환되어 점등된다.Therefore, the power supply of the vehicle battery 10 applied to the common terminal 18b of the movable switch of the relay 18 is applied to the traveling beam terminal 14b through the output terminal 18c. Thus, the headlamp is turned on from the high beam to the low beam.
이중 미설명된 컴비네이션스위치(12)의 선택단자(12a)는 헤드램프벌브(14)를 오프시킬 때 접속되는 단자를 나타내는 것이고, 헤드램프벌브(14)의 단자(14a)는 자동차배터리(10)의 마이너스측 전원에 연결되는 단자이다.The selection terminal 12a of the combination switch 12, which is not described above, represents a terminal connected when the head lamp bulb 14 is turned off, and the terminal 14a of the head lamp bulb 14 is an automobile battery 10. This terminal is connected to the negative power of.
상기한 바와 같이 본 발명은 컴비네이션스위치(12)에 주행빔선택단자와 변환빔선택단자를 구비하고, 그의 접속상태를 변환빔선택단자에 위치시키면 마주오는 차량의 전조등에 의한 불빛 감지여부에 따라 상향등과 하향등의 점등이 자동조정되므로써 상대방 차량 운전자의 시야확보에 지장을 주지않게 될 뿐만 아니라 운전조작의 편리함을 제공할 수 있는 장점이 있다.As described above, the present invention includes a driving beam selection terminal and a conversion beam selection terminal in the combination switch 12, and when the connection state thereof is located in the conversion beam selection terminal, the upper light is detected depending on whether the light of the headlight of the oncoming vehicle is detected. By automatically adjusting the lighting of the lights and the downlight, not only does it interfere with securing the vision of the other vehicle driver, but also has the advantage of providing convenience of driving operation.
