이하, 본 발명은 첨부된 예시도면을 참조하여 상세히 설명한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 발명에 따른 전조등이 장착된 사시도이고, 제2도는 본 발명에 따른 자동전조등장치의 회로도로서, 본 발명은 자동차의 주행속도를 전기적인 신호로 감지하는 기존의 속도센서(1)와; 운전자가 수동전조등방식과 자동전조등방식을 선택 할 수 있도록 설치된 시스템작동스위치(2)와; 운전자가 전조등을 온(ON)/오프(OFF)시킬 수 있도록 설치된 기존의 전조등작동스위치(3)와; 상기 속도센서(1)와 시스템작동스위치(2) 및 전조등작동스위치(3)에서 출력되는 신호들을 입력받아 소정프로그램을 통해 그 상태를 파악한 후 그 결과에 부응하는 제어신호(즉, 제3도에 도시한 바와 같은 펄스신호와 방향신호)를 스텝모터 드라이버(5)로 출력시켜 주는 전자제어유니트(4)와; 상기 전자제어유니트(4)에서 출력되는 구동신호를 매개로 그 구동이 제어되어 전자등(K)의 방사량을 조절하기 위한 스템모터의 구동을 제어하는 스텝모터 드라이버(5)와; 상기 스텝모터 드라이버(5)에 의해 정해진 방사량에 부응하는 회전수로 작동하는 스템모터(6)와; 밧데리(9)와 전조등(K)의 일측단자 사이에 전압단자(8a)와 접지단자(8c)가 연결되고 그 가동레버(8b)는 커플링을 매개로 상기 스텝모터(6)에 연결되어 상기 스텝모터(6)의 회전수에 부응하여 그 저항값이 가변되는 변화되는 가변저항(8)으로 구성된 것을 특징으로 한다.FIG. 1 is a perspective view of a headlamp according to the present invention, FIG. 2 is a circuit diagram of an automatic headlamp apparatus according to the present invention, ; A system operation switch (2) installed so that the driver can select the manual headlight type and the automatic headlight type; An existing headlight operation switch 3 provided so that the driver can turn on / off the headlight; The signals output from the speed sensor 1, the system operation switch 2, and the headlight operation switch 3 are received and the state of the signals is determined through a predetermined program. Then, control signals corresponding to the results An electronic control unit 4 for outputting a pulse signal and a direction signal as shown in the figure to the step motor driver 5; A step motor driver 5 for controlling driving of a stem motor for controlling the amount of radiation of the electronic lamp K by controlling the driving of the driving motor via the driving signal output from the electronic control unit 4; A stem motor 6 operated at a rotation speed corresponding to the radiation amount set by the step motor driver 5; A voltage terminal 8a and a ground terminal 8c are connected between the battery 9 and one terminal of the headlight K and the movable lever 8b is connected to the step motor 6 via a coupling, And a variable resistor (8) whose resistance value varies in response to the number of revolutions of the step motor (6).
이와 같은 본 발명 장치가 설치된 자동차를 운행하기 위해 운전자가 상기 전조등작동스위치(3)를 온(ON)시킴과 더불어 시스템작동스위치(2)를 자동전조등방식으로 선택해 놓은 다음 주행을 시작하게 되면, 속고센서(1)가 펄스형태의 주행속도신호를 감지하여 전압으로 바꾼 뒤 그 신호를 전자제어유니트(4)에 입력시키게 되고, 이 전자제어유니트(4)는 입력된 신호를 소정프로그램을 통해 파악한 후 그 결과를 펄스신호와 방향신호로 바꾸어 스텝모터드라이버(5)로 출력시키게 한다.When the driver turns on the headlamp actuation switch 3 to operate the vehicle equipped with the apparatus of the present invention and then starts driving after selecting the system operation switch 2 in the automatic headlamp system, The sensor 1 senses a pulse-like running speed signal and converts it into a voltage and inputs the signal to the electronic control unit 4. The electronic control unit 4 recognizes the inputted signal through a predetermined program And converts the result into a pulse signal and a direction signal, and outputs the pulse signal and the direction signal to the step motor driver 5.
따라서, 상기 스텝모터드라이버(5)는 주행속도에 비례되게 전조등(K)의 방사량을 조절하기 위한 구동신호를 스템모터(6)로 출력시키게 되므로 상기 스텝모터(6)는 전조등(K)의 방사량과 비례되는 회전수로 회전하게 되므로 커플링을 매개로 이에 연결된 가변저항(8)의 가변레버(8b)가 회전되어 밧데리(9)로부터 공급되는 전원전압이 상기 가변저항(8)의 저항값에 부응한 만큼 드롭된 후 상기 전조등(K)에 인가되게 되어 상기 전조등(K)의 밝기가 가변저항(8)을 통해 공급되는 전압에 부응하는 밝기로 점등된다.Therefore, the step motor driver 5 outputs the drive signal for adjusting the radiation amount of the headlight K to the stem motor 6 in proportion to the running speed, The variable lever 8b of the variable resistor 8 connected to the variable resistor 8 is rotated through the coupling so that the power supply voltage supplied from the battery 9 is reduced to the resistance value of the variable resistor 8 The brightness of the headlight K is turned on at the brightness corresponding to the voltage supplied through the variable resistor 8. [
이때, 자동차의 주행속도와 전조등(K)의 밝기와의 관계는 제5도에 도시된 바와 같다.At this time, the relationship between the traveling speed of the automobile and the brightness of the headlight K is as shown in FIG.
즉, 자동차의 주행속도가 50Km/h가 될 때 까지는 가변저항(8)의 특성상 전조등(K)의 밝기가 급격히 밝아지게 되고, 50Km/h이후에서는 밝기가 완만하게 증가되다가 100Km/h 이상에서는 전조등(K)의 밝기가 가장 밝은 상태가 유지됨을 알 수 있다.In other words, the brightness of the headlight K rapidly becomes bright due to the characteristic of the variable resistor 8 until the running speed of the automobile reaches 50 km / h, and the brightness gradually increases after 50 km / h, (K) is maintained at the brightest state.
이상 설명한 바와 같이 본 발명은, 자동차의 주행속도를 감지하는 속도센서, 수동/자동전조등방식을 선택적할 수 있는 시스템작동스위치, 전조등의 온/오프 작동을 할 수 있는 전조등작동스위치, 상기 속도센서와 시스템작동스위치 및 전조등 작동스위치의 상태에 부응하여 스텝모터의 구동신호를 변화시키는 전자제어유니트, 전조등의 방사량을 조절하기 위해 가변저항의 가동레버와 연결된 스템모터의 회전방향 및 회전수를 조절하는 스템모터드라이버, 방사량과 비례되게 회전수가 제어되는 스텝모터, 상기 스템모터에 의해 각 단자간의 저항값이 변화되어 전조등에 인가되는 전압을 가변하는 가변저항, 전원인 밧데리 및 전조등으로 구성되어 있으므로, 야간 주행시 자동차의 전조등 밝기가 주행속도와 비례하여 자동적으로 조절되므로 운전자의 편의성이 향상될 뿐만 아니라 이로 인해 상품성이 증진되는 등의 효과가 있는 것이다.As described above, according to the present invention, there is provided a vehicular automatic transmission including a speed sensor for detecting a traveling speed of a vehicle, a system operation switch capable of selecting a manual / automatic headlight type, a headlight operation switch capable of on / off operation of a headlight, An electronic control unit for changing the driving signal of the step motor in accordance with the state of the system operation switch and the head lamp operation switch, a stem for adjusting the rotation direction and the rotation number of the stem motor connected to the movable lever of the variable resistor, A motor driver, a step motor whose rotation rate is proportional to the radiation amount, a variable resistor which changes the resistance value between the terminals by the stem motor to vary the voltage applied to the headlight, a battery as a power source, and a headlight. Since the headlight brightness of the car is automatically adjusted in proportion to the driving speed, Not only the convenience is improved but also the merchantability is improved.
