Description

헤드램프의 조사각도 자동조절장치{apparatus for adjusting the irradiation angle of a head lamp automatically}{Apparatus for adjusting the irradiation angle of a head lamp automatically}

본 발명은 자동차의 헤드램프 조사각도 조절장치에 관한 것으로, 특히 적재상태 또는 승차상태에 따른 차체의 기울기에 관계없이 헤드램프의 조사각도를 수평으로 유지되도록 조절하는 헤드램프의 조사각도 자동조절장치에 관한 것이다.The present invention relates to an apparatus for adjusting the irradiation angle of a head lamp of a vehicle, and more particularly, to an apparatus for automatically adjusting the irradiation angle of a head lamp for adjusting the irradiation angle of a head lamp to be maintained horizontally regardless of the inclination of the vehicle body according to a loaded state or a riding state. It is about.

일반적으로 자동차의 헤드램프의 조사각도는 제조당시에 설정되어 있으며,차량의 사용기간 중에 헤드램프의 조사각도를 변경하고자 할 때는, 헤드램프의 일측에 마련된 헤드램프 조사각도 조절볼트 등을 조작하여야 한다. 이때, 차량을 평지에 정지시켜야 하는 불편이 따르게 된다.In general, the irradiation angle of the head lamp of the vehicle is set at the time of manufacture, and when the irradiation angle of the head lamp is to be changed during the use period of the vehicle, the head lamp irradiation angle adjusting bolt provided on one side of the head lamp must be operated. At this time, the inconvenience of having to stop the vehicle on a flat.

이와 같은 불편을 해소하기 위하여, 헤드램프에 헤드램프의 조사각도를 조절할 수 있는 모터 등을 장착하고, 운전석에서 모터를 조작할 수 있는 헤드램프 조사각도 조절장치를 장착하여 조사각도를 조절하였다. 즉, 운전석에서 운전자가 조사각 조절스위치를 조작하여 헤드램프의 조사각도를 0, 1, 2, 3단계로 조절하는 것이다.In order to alleviate this inconvenience, the head lamp is equipped with a motor for controlling the irradiation angle of the head lamp, and the head lamp irradiation angle adjusting device for operating the motor in the driver's seat is adjusted to adjust the irradiation angle. In other words, in the driver's seat, the driver operates the irradiation angle adjusting switch to adjust the irradiation angle of the headlamp in 0, 1, 2, and 3 steps.

예를 들어, 뒷자석에만 승객이 탑승하게 되거나 트렁크에 많은 짐이 적재되어 차량의 앞부분이 뒷부분 보다 들려서 헤드램프가 상향 조사되는 경우, 운전자는 조사각 조절스위치를 조작하여 헤드램프의 조사각도를 하향 조절해야 한다. 그리고 차량의 뒷부분이 앞부분 보다 들려서 헤드램프가 하향 조사되는 경우에는 조사각 조절스위치를 조작하여 헤드램프의 조사각도를 상향 조절해야 한다.For example, if the passengers are only occupied in the rear seats or if there is a lot of luggage in the trunk and the front part of the vehicle is lifted above the rear part and the headlamp is irradiated upward, the driver operates the angle adjustment switch to lower the headlamp irradiation angle You have to adjust it. When the headlamp is irradiated downward because the rear portion of the vehicle is lifted from the front portion, the irradiation angle of the headlamp should be adjusted upward by operating the irradiation angle adjusting switch.

이와 같이, 종래의 헤드램프 조사각도 조절장치는 차체의 앞 뒤 기울기에 대응하여 운전자가 스위치 조작으로 일일이 헤드램프의 조사각도를 조절해야 하는 불편함이 있었고, 운전자가 조사각도를 조절결과 조사각도가 수평을 유지하기가 어려운 문제점이 있었다.As such, the conventional headlamp irradiation angle adjusting device is inconvenient that the driver has to adjust the irradiation angle of the headlamp by the switch operation in response to the front and rear tilt of the vehicle body, and the driver adjusts the irradiation angle. There was a problem that it was difficult to keep level.

본 발명의 목적은 종래의 문제점을 해소하기 위한 것으로, 특히 적재상태 또는 승차상태에 따른 차체의 기울어짐에 따라 변동되는 헤드램프의 조사각도를 자동으로 조절하여 헤드램프의 조사각도가 항상 수평을 유지하도록 조절하는 헤드램프의 조사각도 자동조절장치에 관한 것이다.An object of the present invention is to solve the conventional problems, in particular to automatically adjust the irradiation angle of the headlamp fluctuating according to the inclination of the vehicle body according to the loading state or riding state, the irradiation angle of the headlamp is always kept horizontal The irradiation angle of the headlamp to adjust so that the automatic control device.

본 발명 헤드램프의 조사각도 자동조절장치는 헤드램프의 반사경과 수평위치에 설치되고, 반사경의 상하움직임에 따라 연동되며, 차체의 앞 뒤 기울기를 검출하는 수평감지센서와; 상기 수평감지센서로부터 입력되는 앞 뒤 기울기신호에 따라 헤드램프의 반사경을 조정하여 헤드램프의 조사각도를 조절하는 조사각조정부를 포함하여 구성되는 것을 특징으로 한다.Automatically adjusting the irradiation angle of the headlamp of the present invention is installed in a horizontal position with the reflector of the headlamp, interlocked in accordance with the vertical movement of the reflector, the horizontal detection sensor for detecting the front and rear tilt of the vehicle body; And an irradiation angle adjusting unit for adjusting an irradiation angle of the head lamp by adjusting a reflecting mirror of the head lamp according to the front and rear tilt signals input from the horizontal sensing sensor.

본 발명의 실시예를 도 1 내지 도 4를 참조하여 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4 as follows.

본 발명 헤드램프의 조사각도 자동조절장치는 도 1과 도 2에 나타낸 바와 같이, 헤드램프(10)의 반사경(11)과 수평위치에 설치되고, 반사경의 상하움직임에 따라 연동되며, 차체의 앞 뒤 기울기를 검출하는 수평감지센서(20)와; 상기 수평감지센서(20)로부터 입력되는 앞 뒤 기울기신호에 따라 헤드램프의 반사경(11)을 조정하여 헤드램프(10)의 조사각도를 조절하는 조사각조정부(30)를 포함하여 구성된다.1 and 2, the automatic adjustment of the irradiation angle of the headlamp of the present invention is installed in a horizontal position with the reflector 11 of the headlamp 10, and is interlocked according to the vertical movement of the reflector, in front of the vehicle body. A horizontal sensor 20 for detecting a rear tilt; The irradiation angle adjusting unit 30 is configured to adjust the irradiation angle of the head lamp 10 by adjusting the reflecting mirror 11 of the head lamp according to the front and rear tilt signals input from the horizontal sensor 20.

상기 수평감지센서(20)는 헤드램프(10)의 반사경(11)과 수평위치에 설치된다.The horizontal sensor 20 is installed in a horizontal position with the reflector 11 of the head lamp 10.

상기 조사각조정부(30)는 모터로 이루어져 입력되는 앞 뒤 기울기 신호에 따라 정회전 또는 역회전되어 상기 헤드램프의 반사경(11)을 상향 또는 하향 조절한다. 이때, 상기 수평감지센서(20) 상기 반사경(11)의 상하움직임에 따라 연동된다.The irradiation angle adjusting unit 30 is made of a motor to be rotated forward or reverse according to the front and rear tilt signals input to adjust the reflector 11 of the headlamp upward or downward. At this time, the horizontal sensor 20 is interlocked with the vertical movement of the reflector (11).

즉, 차체가 수평을 유지하는 경우, 도 2에서와 같이, 상기 수평감지센서(20)의 이동접점(21)은 "중립"상태가 된다. 이에 따라, 헤드램프(10)의 조사각도는 지면에 대하여 수평으로 유지된다.That is, when the vehicle body is horizontal, as shown in Figure 2, the moving contact 21 of the horizontal sensor 20 is in a "neutral" state. Accordingly, the irradiation angle of the headlamp 10 is kept horizontal with respect to the ground.

차체가 뒤로 기울어진 경우, 도 3에서와 같이, 상기 수평감지센서(20)의 이동접점(21)이 "-단자" 쪽으로 이동되어 조사각조정부(30)에 "-전압"을 인가한다. 이에 따라, 상기 조사각조정부(30)는 상기 수평감지센서(20)로부터 "-전압"이 "0전압"이 될 때까지 헤드램프의 반사경(11)을 하향 조절한다. 이에 따라, 차체는 뒤로 기울어진 상태이지만 헤드램프(10)의 조사각도는 수평으로 유지된다.When the vehicle body is inclined backward, as shown in FIG. 3, the moving contact 21 of the horizontal sensor 20 is moved toward the “-terminal” to apply the “−voltage” to the irradiation angle adjusting unit 30. Accordingly, the irradiation angle adjusting unit 30 adjusts the reflecting mirror 11 of the head lamp downward until the "-voltage" becomes "0 voltage" from the horizontal sensor 20. Accordingly, although the vehicle body is inclined backward, the irradiation angle of the headlamp 10 is kept horizontal.

또한, 차체가 앞으로 기울어진 경우, 도 4에서와 같이, 상기 수평감지센서(20)의 이동접점(21)이 "+단자" 쪽으로 이동되어 조사각조정부(30)에 "+전압"을 인가한다. 이에 따라, 상기 조사각조정부(30)는 상기 수평감지센서(20)로부터 "+전압"이 "0전압"이 될 때까지 헤드램프의 반사경(11)을 상향 조절한다. 이에 따라, 차체는 앞으로 기울어진 상태이지만 헤드램프(10)의 조사각도는 수평으로 유지된다.In addition, when the vehicle body is inclined forward, as shown in FIG. 4, the movable contact 21 of the horizontal sensor 20 is moved toward the "+ terminal" to apply "+ voltage" to the irradiation angle adjusting unit 30. . Accordingly, the irradiation angle adjusting unit 30 adjusts the reflector 11 of the headlamp upward until the "+ voltage" becomes "0 voltage" from the horizontal sensor 20. Accordingly, the vehicle body is inclined forward, but the irradiation angle of the headlamp 10 is kept horizontal.

상기에서는 평지에서 차체가 앞으로 또는 뒤로 기울어진 경우 헤드램프의 조사각도 조절에 대하여 설명하였지만, 평지에서 차체가 앞으로 기울어진 경우는 내리막 길에서의 조사각도 조절과 동일하고, 평지에서 차체가 뒤로 기울어진 경우는 오르막 길에서의 조사각도 조절과 동일하다.Although the above described the adjustment of the headlamp irradiation angle when the vehicle body is inclined forward or backward on a flat surface, when the vehicle body is inclined forward on a flat surface, it is the same as the adjustment of the irradiation angle on a downhill road. The case is the same as the adjustment of the irradiation angle on the uphill road.

이와 같이, 본 발명 헤드램프의 조사각도 자동조절장치는 경사길에서의 헤드램프의 조사각도를 자동으로 조절할 뿐만 아니라 평지에서 차체의 앞 뒤 기울기에따른 헤드램프의 조사각도를 자동으로 조절하여 조사각도를 항상 수평으로 유지시키는 것으로, 야간 운행시 시계성을 향상시키어 안전운행에 기여하며, 운전자의 편의성을 향상시키며, 제어장치가 필요 없어 원가절감 및 공정을 단순화시키는 유용한 것이다.As such, the automatic adjustment of the irradiation angle of the headlamp of the present invention automatically adjusts the irradiation angle of the headlamp on the inclined road as well as automatically adjusting the irradiation angle of the headlamp according to the front and rear tilt of the vehicle body on a flat surface. By keeping it horizontal at all times, it improves visibility at night operation, contributes to safe operation, improves the convenience of the driver, and it is useful to reduce costs and simplify the process without the need for a control device.
