이하, 첨부 도면에 의거하여 본 발명에 따른 장치의 실시예에 대해 상세히 설명한다.Hereinafter, an embodiment of the apparatus according to the present invention will be described in detail with reference to the accompanying drawings.
도 1은 자동차의 야간 주행시 자동차 헤드 라이트의 높낮이를 자동으로 조절하기 위한 장치의 구성도이다.1 is a block diagram of a device for automatically adjusting the height of a vehicle headlight during nighttime driving of the vehicle.
도 1을 참조하면, 자동차 헤드 라이트의 외부 케이스인 하우징(19)내에 자동차 헤드 라이트의 광원 벌브(14)의 빛을 모아서 반사시키는 반사경(13)이 설치되고, 반사경(13)의 후면 상부에 힌지 핀(12)이 설치되는 한편, 상기 하우징(19)의 내측면 상부에 설치된 브라켓(21)에 상기 힌지 핀(12)을 회동 가능하게 설치함으로써 반사경(13)이 힌지 핀(12)을 중심으로 좌우로 회동될 수 있다.1, a reflector 13 for collecting and reflecting light of a light source bulb 14 of an automobile headlight is provided in a housing 19, which is an outer case of an automobile headlight. The hinge pin 12 is rotatably mounted on the bracket 21 provided on the inner side surface of the housing 19 so that the reflecting mirror 13 can be rotated about the hinge pin 12 It can be pivoted from side to side.
그리고, 하우징(19)내에 설치된 모터(18)에 공지의 기어 장치(16)를 설치하고, 모터의 축이 회전함에 따라 기어 장치에 의해 좌우로 이동하는 막대(15)가 상기 반사경(13)의 하부 외측면에 부착되고, 상기 막대(15)가 이동되는 범위를 한정하는 제1 스톱퍼(a) 및 제2 스톱퍼(b)가 하우징내에 설치된다.A known gear device 16 is provided in a motor 19 provided in the housing 19. A bar 15 moving right and left by the gear device as the shaft of the motor rotates is provided on the side of the reflector 13 A first stopper (a) and a second stopper (b) are attached to the lower outer side surface of the housing, the first stopper a and the second stopper b defining the range in which the rod 15 is moved.
이때, 상기 막대(15)가 상기 제1 스톱퍼(a)에 접촉되도록 이동하게 되면 상기 반사경(13)이 A 방향으로 아래로 향하게됨으로써, 로우빔을 조사하게 되고, 상기 막대(15)가 상기 제2 스톱퍼(b)에 접촉되도록 이동하며 상기 반사경(13)이 B의 방향으로 위로 향하게 되어 하이빔을 조사하게 된다.At this time, when the rod 15 moves so as to contact the first stopper a, the reflector 13 is directed downward in the A direction to irradiate the low beam, 2 stopper b and the reflector 13 is directed upward in the direction of B to irradiate the high beam.
한편, 포토 센서(17)는 전방에 접근하는 자동차의 헤드 라이트 불빛을 감지하여 광량에 따른 신호 전류를 전자 제어 장치(10)로 공급하고, 입력받은 신호 전류가 설정치를 넘어설 경우 상기 전자 제어 장치(10)는 상기 모터(18) 축에 부착된 기어 장치(16)를 소정 방향으로 회전시킴으로써, 상기 조절 막대(15)가 제1 스톱퍼(a)에 접촉되도록 이동하면, 자동차의 헤드 라이트는 로우 빔을 조사시키는 것이다.On the other hand, the photo sensor 17 senses the headlight light of the automobile approaching the front and supplies the signal current according to the light amount to the electronic control unit 10, and when the inputted signal current exceeds the set value, When the control rod 15 moves so as to contact the first stopper a by rotating the gear device 16 attached to the shaft of the motor 18 in a predetermined direction, Beam.
이와는 반대로, 상기 포토 센서(17)로부터 감지된 광도가 설정 기준 이하일 경우 상기 막대(15)가 제2 스톱퍼(b)에 접촉되도록 모터 구동 신호를 발생하여 반사경(13)이 하이빔 위치 B로 회동되도록 한다.On the other hand, when the luminous intensity detected from the photosensor 17 is lower than the predetermined reference value, the bar 15 generates a motor driving signal to contact the second stopper b so that the reflector 13 is rotated to the high beam position B do.
그리고, 상기와 같은 자동차 헤드 라이트의 높낮이 조절장치는 운전자가 수동으로 장치의 동작을 온/오프할 수 있는 스위치인 자동 조절용 스위치(SW1)가 구비되고, 상기 헤드 라이트의 하이빔 램프를 수동으로 온/오프할 수 있는 통상의 라이트 스위치(14)가 설치된다.The height adjustment device of the automobile headlight includes a switch SW1 for automatically adjusting the operation of the device by the driver, and the high beam lamp of the headlight is manually turned on / A normal light switch 14 is provided which can be turned off.
도 1에서 미설명된 상기 참조 번호 20은 하우징 캡이고, θ는 하이빔과 로우빔과의 각도 차이를 나타낸다.In FIG. 1, reference numeral 20 is a housing cap, and? Represents an angle difference between the high beam and the low beam.
상기와 같은 장치의 동작을 전자 제어 장치(10)의 동작 프로그램의 흐름도인 도 2를 참조하여 설명하면, 첫번째 스텝으로서, 자동 조절용 스위치(SW1)가 턴온되었는지를 판단하는 단계와, 두번째 스텝으로서, 헤드 라이트 하이빔 스위치가 턴온되었는지를 판단하는 단계와, 상기 두 조건을 만족하게 되면, 세번째 스텝으로서, 포토 센서(17)로부터 감지된 광도가 기준 광도보다 높은지를 판단하는 단계와, 기준 광도보다 높을 경우 상기 전자 제어 장치(10)는 모터(18)에 부착된 기어 장치(16)를 소정 방향으로 반사경(13)이 로우 방향 A를 향하도록 회동시키는 모터 구동 신호를 발생하고, 이와는 반대로 기준 광도보다 낮을 경우 상기 반사경(13)이 하이빔 방향 B를 향하도록 모터 구동 신호를 발생함으로써, 자동차 헤드 라이트가 하이 빔 조사 위치를 그대로 유지하게 만든다.2, which is a flow chart of an operation program of the electronic control unit 10, the operation of the above-described apparatus will be described. As a first step, it is determined whether or not the automatic adjustment switch SW1 is turned on. Determining whether the light intensity detected by the photosensor (17) is higher than a reference luminous intensity as a third step when the headlight high beam switch is turned on; The electronic control apparatus 10 generates a motor drive signal for rotating the gear device 16 attached to the motor 18 in the predetermined direction so that the reflecting mirror 13 is directed in the row direction A and conversely, , The motor drive signal is generated so that the reflector 13 is directed in the high beam direction B, so that the vehicle headlight is maintained at the high beam irradiation position It creates.
상술한 바와 같이 본 발명의 장치에 의하면, 자동차의 야간 주행시에 맞은 편에 자동차가 접근할 경우 하이빔을 로우빔으로 전환시켜주는 동작을 자동으로 수행되도록함으로써, 자동차의 야간 주행시의 편의성 및 운전 쾌적성을 높힐 수 있다.As described above, according to the apparatus of the present invention, when the automobile is approaching at the time of night driving of the automobile, the operation of automatically switching the high beam to the low beam is performed automatically, thereby improving convenience and comfort .
