It is configured to be lighted.
상기 휠 각도센서(10)는 차량의 조향각도를 감지하는 센서로서, 차량의 조향 각도에 따라 상기 컨트롤러(20)로 상이한 신호를 출력하도록 구성되며, 상기 컨트롤러(20)는 상기 휠 각도센서(10)로부터 입력되는 신호에 따라 소정의 시간동안 정역방향의 전류를 구동부(30)로 출력하도록 구성된다. 그리고, 상기 구동부(30)는 상기 컨트롤로(20)로부터 입력되는 전류에 따라 상기 헤드램프 벌브(L)를 상기 궤적홈(40a)을 따라 좌우측으로 이동시키는 수단으로써, 모터(31), 피니언(32) 및 이송 브래킷(33)으로 이루어질 수 있다.The wheel angle sensor 10 is a sensor for detecting a steering angle of the vehicle, and is configured to output different signals to the controller 20 according to the steering angle of the vehicle, and the controller 20 is configured to output the wheel angle sensor 10. According to the signal input from the) is configured to output the forward and reverse current to the drive unit 30 for a predetermined time. In addition, the driving unit 30 is a means for moving the headlamp bulb L to the left and right along the trajectory groove 40a according to a current input from the control path 20. 32) and the transfer bracket 33.
상기 이송 브래킷(33)은 일측에 호형의 랙(33a)이 형성되며 상기 헤드램프 벌브(L)의 몸체부에 고정되게 장착되며, 이 호형의 랙(33a)에 피니언(32)이 맞물리도록 구성되는데, 이때, 상기 피니언(32)의 회전에 의해 이송되는 랙(33a)에 따라 상기 헤드램프 벌브(L)가 궤적홈(40a) 내에서 좌우측으로 이송될 수 있도록 구성된다. 그리고, 상기 모터(31)는 상기 컨트롤러(20)로부터 입력되는 전류에 따라 상기 피니언(32)을 정역회전시키는 수단으로서, 회전각도의 조절이 용이한 스텝모터를 이용하는 것이 바람직하다.The conveying bracket 33 has an arc-shaped rack 33a formed at one side and is fixedly mounted to the body portion of the headlamp bulb L, and configured to engage the pinion 32 with the arc-shaped rack 33a. At this time, the head lamp bulb (L) is configured to be transferred to the left and right in the trajectory groove (40a) according to the rack (33a) is transported by the rotation of the pinion (32). In addition, the motor 31 is a means for forward and reverse rotation of the pinion 32 in accordance with the current input from the controller 20, it is preferable to use a step motor easy to adjust the rotation angle.
상기와 같은 구성에 의하여, 차량이 우회전을 하기 위해 차량의 휠이 우측으로 틀어지며, 휠 각도센서(10)에 의해 이를 감지한 컨트롤러(20)에서 상기 모터(31)로 정방향의 전류(헤드램프 벌브가 우측으로 이송되도록 모터를 회전시키는 전류)를 출력시킨다. 이에 따라, 모터(31)와 함께 정방향으로 회전되는 피니언(32)에 의해 랙(33a)이 우측 상 방향으로 이송됨에 따라 헤드램프 벌브(L)가 궤적홈(40a) 내에서 우측 상향으로 이송됨으로써, 차량의 전방부가 완전히 우측으로 회전되기 전에, 우측으로 이송된 헤드램프 벌브(L)에 의하여 운전자가 우측도로의 상황을 인지할 수 있게 된다. 그리고, 차량의 전방부가 완전히 우측으로 틀어진 다음에는, 상기 휠 각도센서(10)가 제로(0)인 상태(최초의 상태)로 돌아오게 되며, 상기 휠 각도센서(10)에 의해 이를 감지한 컨트롤러(20)에서 상기 모터(31)오 역방향의 전류를 인가함으로써, 상기 헤드램프 벌브(L)가 궤적홈(40a)을 따라 이송되어 중앙의 위치로 되돌아오게 된다. 또한, 차량이 좌회전을 하기 위해 차량의 휠이 좌측으로 틀어질 경우에도 상기와 동일한 과정을 통하여 상기 헤드램프 벌브(L)가 좌측 상 방향으로 이송됨으로써, 운전자가 회전하려는 좌측도로의 상황을 미리 인지할 수 있게 된다.By the above configuration, the wheel of the vehicle is turned to the right in order for the vehicle to turn right, and the controller 20 detects this by the wheel angle sensor 10 in the forward direction of the current to the motor 31 (headlamps). Current to rotate the motor so that the bulb is transferred to the right. Accordingly, as the rack 33a is moved upward and upward by the pinion 32 which is rotated in the forward direction together with the motor 31, the headlamp bulb L is conveyed to the right upward in the trajectory groove 40a. Before the front part of the vehicle is completely rotated to the right, the headlamp bulb L transferred to the right enables the driver to recognize the situation on the right road. Then, after the front part of the vehicle is completely twisted to the right, the wheel angle sensor 10 returns to the zero (first state), and the controller detects this by the wheel angle sensor 10. By applying a current in the opposite direction to the motor 31 at 20, the headlamp bulb L is transported along the trajectory groove 40a and returned to the center position. In addition, even when the wheel of the vehicle is turned to the left to make the vehicle turn left, the headlamp bulb L is transferred to the upper left direction through the same process as described above, so that the driver knows in advance the situation of the left road to be rotated. You can do it.
상기 일 실시예에 의하여 알 수 있는 바와 같이, 본 고안을 따른 조향각도에 따른 헤드램프의 조사각도 조절장치에 의하여, 차량의 전방부가 완전히 회전되기 전에 헤드램프 벌브가 회전하려는 도로를 비추게 됨으로써, 운전자가 회전하려는 방향의 도로상황을 미리 인지할 수 있게 되며, 이에 따라 차량의 좌우회전시 운전자가 안전 운행을 할 수 있는 효과가 있다.As can be seen by the above embodiment, by the irradiation angle adjusting device of the headlamp according to the steering angle according to the present invention, the headlamp bulb is illuminated by the road to be rotated before the front of the vehicle is completely rotated, The driver can recognize in advance the road situation in the direction in which the driver intends to turn, and thus, the driver can safely drive when the vehicle rotates left and right.
이상에서 본 고안의 일 실시예에 따른 조향각도에 따른 헤드램프의 조사각도 조절장치에 대하여 설명하였으나, 본 고안은 이에 한정하지 아니하며, 당업자라면 여러 가지로 그 변형과 응용이 가능할 것이다.The irradiation angle adjusting device of the headlamp according to the steering angle according to an embodiment of the present invention has been described above, but the present invention is not limited thereto, and those skilled in the art will be able to variously modify and apply the same.
