Abstract

차체에 포텐셜 미터를 이용한 수평센서를 수평으로 고정하고 전조등과 동축으로 고정된 포텐셜 미터를 각도센서로 이용하여 수평센서와 각도 센서의 전압이 상이할 경우 전조등 각도 조절용 모터를 구동하여 전압이 동일 할 때 까지 전조등의 각도를 조절한다. 수평센서의 무게추는 항상 수평을 유지하므로 차체의 각도에 따라 수평센서의 저항치가 변화하고, 이에따라 출력단자 전압이 변화하며 각도센서는 전조등의 현재 각도에 따라 출력단자 전압이 결정 된다. 수평센서와 각도센서의 전압차이를 감지하여 전조등 각도 조절용 모터를 구동하여 수평센서의 전압과 동일한 전압이 각도센서의 출력단자에 나올 때 까지 전조등 각도를 조절한다. 수평센서는 차내에서 자동 수평 조절과 수동 각도 조절 기능을 선택 할 수 있도록 회로를 구성하여 운전자 요구에 따라 차내에서 전조등 각도를 조절 할 수 있다.When the horizontal sensor using the potential meter is fixed to the body horizontally and the potential meter fixed coaxially with the headlight is used as the angle sensor, when the voltage between the horizontal sensor and the angle sensor is different, the motor for the headlight angle control motor is operated to have the same voltage. Adjust the headlight angle until Since the weight of the horizontal sensor is always horizontal, the resistance value of the horizontal sensor changes according to the angle of the vehicle body. The output terminal voltage changes accordingly, and the angle sensor determines the output terminal voltage according to the current angle of the headlamp. By detecting the voltage difference between the horizontal sensor and the angle sensor, it drives the motor for the headlight angle control and adjusts the headlight angle until the same voltage as the voltage of the horizontal sensor appears on the output terminal of the angle sensor. The level sensor is configured to select auto leveling and manual angle adjustment function in the car, and can adjust the headlight angle in the car according to the driver's demand.

Description

자동 수평 조절 헤드라이트 {AUTO BALANCE HEADLIGHT}Auto-leveling headlights {AUTO BALANCE HEADLIGHT}

자동차 전조등은 상향등과 하향등 두가지 기능이 있으나 각도는 항상 고정되어 있다. 각도를 조정하기 위해서는 수평조절 나사나 혹은 유사한 조절 부품을 차량 정지 상태에서 조정 해야한다.Automotive headlights have two functions, the high beam and the low beam, but the angle is always fixed. To adjust the angle, the leveling screw or similar adjustment part must be adjusted while the vehicle is stationary.

차체와 수평으로 부착된 포텐셜 미터의 회전 각도에 따른 저항치 변화를 이용 수평 센서를 구성하고 전조등과 동축으로 고정된 포텐셜 미터를 전조등 각도센서를 구성한다. 수편센서와 각도센서의 저항치가 차이가 날 경우 전압이 상이하게 나타나고 이 전압차이에 따라 전조등 각도 조절용 구동 모터가 회전하여 수평센서와 각도센서의 전압이 동일 할 때 까지 전조등 각도를 조정한다. 수평센서는 실내수동 조절 포텐셜 미터와 선택적으로 운전자가 선택하여 자동 혹은 수동으로 각도를 조정 할 수 있도록 회로가 구성 되어있다. 수평센서와 각도센서의 미세 전압차이에는 전조등 각도가 조절 되지 않도록 일정한 전압 차이가 발생하면 각도조절이 되도록 전압 비교회로를 구성한다. 차체의 각도에 따라 자동으로 전조등 각도를 수평으로 유지하거나 차내의 운전자 요구에 따라 각도를 임의로 조절 할 수 있도록 선택 회로를 구성 한다. 좌측과 우측 전조등은 개별적으로 본 기능을 장착한다.The horizontal sensor is used to change the resistance value according to the rotation angle of the potential meter attached horizontally to the vehicle body, and the headlight angle sensor is composed of the potential meter fixed coaxially with the headlight. If the resistance value between the water sensor and the angle sensor is different, the voltage will be different and according to the voltage difference, adjust the headlight angle until the driving motor for angle adjustment of the headlight rotates and the voltage of the horizontal sensor and the angle sensor is the same. The horizontal sensor consists of a manual adjustment potentiometer and a circuit that allows the operator to select and adjust the angle automatically or manually. In the voltage difference between the horizontal sensor and the angle sensor, the voltage comparison circuit is configured to adjust the angle when a constant voltage difference occurs so that the headlight angle is not adjusted. The selection circuit is configured to automatically maintain the headlight angle horizontally according to the angle of the vehicle body or to arbitrarily adjust the angle according to the needs of the driver in the vehicle. The left and right headlights are equipped with this function separately.

그림3의 포텐셜미터는 축의 회전 각도에 따라 중간단자 C 의 저항치가 변한다. 회전축에 무게추를 고정하면 무게추는 항상 수직 아래 방향으로 향한다. 포텐셜미터를 기울이면 무게추의 무게에 의해서 축이 회전하며 무게추가 아래로 향한다. 이때 포텐셜 미터의 중간 단자 저항치가 변화하며 고정 전압을 포텐셜 미터 양단 A,B 에 가하면 중간 단자 C 의 출력 전압이 각도에 따라 상이하게 출력 된다. 이 기능을 수평 센서로 이용한다. 그림3의 램프 측면도는 램프 각도 조정용 모터와 램프가 벨트로 구동 되도록 되어있다. 램프 상면도의 포텐셜 미터 L 은 램프 각도를 측정하기 위한 각도센서이며, 각도에 따라 중간 단자 C 의 전압이 상이하게 출력된다.In the potentiometer shown in Fig. 3, the resistance of the middle terminal C changes according to the rotation angle of the shaft. When the weight is fixed to the axis of rotation, the weight always points vertically downward. When the potentiometer is tilted, the shaft is rotated by the weight of the weight and the weight is directed downward. At this time, the resistance value of the intermediate terminal of the potential meter changes, and if the fixed voltage is applied to both ends A and B of the potential meter, the output voltage of the intermediate terminal C is differently output according to the angle. Use this function as a horizontal sensor. The lamp side view in Figure 3 shows the lamp angle adjusting motor and the lamp driven by the belt. The potential meter L of the lamp top view is an angle sensor for measuring the lamp angle, and the voltage of the intermediate terminal C is output differently according to the angle.

그림3의 수평센서가 차체에 고정되어 있어 차가 기울 경우 수평센서의 전압이 헤드라이트와 동축 고정된 포텐셜미터의 전압과 일정한 차이 이상 발생하여 릴레이 #1 이나 릴레이 #2 를 작동하여 모터를 구동한다. 모터가 구동하여 헤드라이트 각도가 조절됨과 동시에센서전압과 포텐셜미터 전압이 지정된 전압차이 이내에들어오면 모터 구동이 정지하고 헤드라이트는 조절된 각도로 고정된다. 미세각도 조정을 할 경우 전압 비교회로를 추가하여 릴레이를 작동 할 수도 있다.As the horizontal sensor of Fig. 3 is fixed to the vehicle body, when the car is inclined, the voltage of the horizontal sensor occurs more than a certain difference from the voltage of the potentiometer fixed coaxial with the headlight, and operates the relay # 1 or the relay # 2 to drive the motor. When the motor is driven to adjust the headlight angle and the sensor voltage and the potential meter voltage are within the specified voltage difference, the motor driving is stopped and the headlight is fixed at the adjusted angle. In case of fine angle adjustment, relay can be operated by adding voltage comparison circuit.

수동으로 전조등 각도를 조절 할 경우 수동/자동 스위치를 수동으로 전환하여 운전석에 부착된 수동 조절용 포텐셜 미터를 조정하면 자동 조절과 같은 원리로 전조등이 조절 된다.If you adjust the headlight angle manually, switch the manual / automatic switch manually to adjust the manual adjustment potential meter attached to the driver's seat.

야간 자동차 운전시 그림1 과 같이 경사면을 운전 할 경우 헤드라이트가 차체와 동일하게 움직이므로 전면을 확인하기 힘들어 위험한 상황이 발생한다. 그러나 그림2 와 같이 자동 수평조절 헤드라이트를 설치 할 경우 경사면에 상관없이 항상 수평으로 전면을 밝혀주어 운전자가 항상 전방을 확인 할 수 있게 해 준다. 본 기능은 자동 수평 조절이나 자동 기능을 해제 하면 일반 헤드라이트와 동일하게 고정되며 실내에서 운전자가 필요에 따라 각도를 조절 할 수 있다. 따라서 기존의 차량에 있는 상향등과 하향등을 하나의 기능으로 통합 가능하다. 기존 차량에는 외장형으로 추가 할 수 있다.When driving a car at night as shown in Fig. 1, the headlights move in the same way as the body, so it is difficult to see the front, which creates a dangerous situation. However, when installing the auto leveling headlight as shown in Figure 2, the front of the vehicle is always horizontally, regardless of the slope, so that the driver can always see ahead. This function is fixed like the normal headlight when auto leveling or auto function is off and the driver can adjust the angle as needed in the room. Therefore, it is possible to integrate the high beam and the low beam in the existing vehicle as one function. Existing vehicles can be added externally.
