본 발명은 전조등의 자동절환장치에 관한 것으로서, 더 상세하게는 야간에 마주오는 대향차량의 전조등 빛과 차의 경사로에 위치됨에 따라 전조등의 점등상태가 상향등 또는 하향등으로 자동 절환되도록 한 전조등의 자동절환장치에 관한 것이다.The present invention relates to an automatic switching device of the headlamp, and more particularly, the headlight of the opposite vehicle facing at night and the headlight of the headlight to be automatically switched to the high beam or the downlight as it is located on the ramp of the car. It relates to a switching device.

일반적으로 차의 전조등에는 조사각이 높은 상향등 램프와 조사각이 낮은 하향등 램프가 동시에 구비되어, 제 1 도에서 보인바와 같이 전조등스위치(S1)를 켠상태에서 조향핸들에 있는 전조등스위치(S1)에 의해 공급되는 전원을 디머스위치(S2)의 조작에 의하여 절환공급함으로써, 전조등(40)의 점등이 상향등(41)의 또는 하향등(42)으로 절환되도록 구성된다.In general, the headlights of the vehicle are provided with a high irradiation angle lamp and a low irradiation angle downlight lamp at the same time, as shown in FIG. 1, the headlight switch S1 of the steering wheel with the headlight switch S1 turned on. By switching and supplying the power supplied by the operation of the dimmer switch S2, the lighting of the headlamp 40 is comprised so that switching to the upper lamp 41 or the lower lamp 42 may be carried out.

이와같은 전조등이 구비된 자동차를 야간운행시, 통상으로 운전자는 좋은 시야를 확보키 위해 가로등이 없는 도로와 같이 시계가 불량한 도로에서는 상향등을 켜고 운행하게 되는데, 이 상향등의 불빛으로 인하여 마주오는 상대운전자는 눈이 부시게 되어 전방시야 확보에 지장를 받게 된다.When driving a car equipped with such a headlight at night, a driver usually turns on and operates a high beam on a road with poor visibility, such as a road without a street lamp, to secure a good view. The eyes will be dazzled, which will interfere with securing the front field of view.

이러한 점을 해결하기 위하여 차가 서로 마주쳐 지나갈 때에는 쌍방이 모두 디머스위치를 조절하여 하향등을 점등시키고 전방에서 마주오는 차량이 없을 때에는 상향등을 점등시킴으로써 시야을 확보함과 동시에 상대운전자의 불편을 감소시켰다.In order to solve this problem, when both cars face each other, both sides control the dimmer switch to turn on the downlight, and when there is no car coming from the front, the uplight is turned on to secure the view and reduce the inconvenience of the relative driver.

그러나, 이러한 수동조작방법은 교행차량이 나타날때마다 매번 전조등을 하향으로 변경시켜야 하므로, 운전자에게 운전 이외의 디머스위치를 자주 조작하여야 하는 번거로움을 주게 된다.However, this manual operation method has to change the headlight downward every time the vehicle appears, which gives the driver the trouble of frequently operating the dimmer switch other than driving.

It became.

이와 같은 문제점을 해결하기 위한 본 발명은 마주오는 대향차량의 전조등 빛을 감지하면 하향등으로 자동절환되고 대향차량이 없을 때는 상향등으로 자동절환되는 전조등의 자동절환장치를 제공하여, 디머스위치 조작에 따른 운전자의 불편을 해소하고 아울러 전조등의 부적절한 조사로 인하여 발생되는 사고를 방지하려는 목적이 있는 것이다.The present invention for solving this problem provides an automatic switching device of the headlight is automatically switched to the downlight when the headlight of the opposite vehicle is detected, and automatically switched to the uplight when there is no opposite vehicle, to the dimmer switch operation The purpose is to solve the driver's inconvenience and prevent accidents caused by improper investigation of the headlights.

또한, 본 발명의 제안이 상대차량에서 조사되는 전조등의 빛감지에 의한 절환작동임을 착안하여, 경사로 등판시에 최정상부근에서 교차시 서로 감지되지 않는 상대차량의 전조등 빛을 고려하여 경사로 등판시에는 전조등이 햐향등으로 조사되도록 하여 상대운전자에게 편의를 제공할 수 있도록 하려는 것이다.In addition, considering that the proposal of the present invention is a switching operation by detecting the light of the headlight irradiated from the relative vehicle, the headlight when climbing the ramp in consideration of the headlight of the relative vehicle that is not detected at the top near the top at the time of the ramp climbing It is intended to provide convenience to the other driver by investigating this direction.

이와 같은 목적을 달성하기 위한 본 발명에 따르면, 운전자에 의해 조작되는 전조등 스위치에 의해 전원이 인가되어 대향차량의 전조등 빛을 감지하는 광감지센서, 상기 광감지센서와 동시에 전원이 공급되어 차의 경사로 등판을 감지하는 경사로감지수단, 상기 광감지센서 및 상기 경사로감지수단의 출력신호에 의한 자동모드 및 운전자의 조작에 의한 수동모드를 선택하는 절환스위치, 그리고 상기 절환스위치의 수동모드시에 상기 전조등스위치를 통해 인가된 전원을 선택적으로 접속하는 디머스위치에서 출력된 각각의 신호에 의해 출력전류의 절환공급을 제어하는 전조등제어부와, 상기 전조등제어부의 출력단에 접속되어 상향등 및 하향등으로 전류를 공급하는 각각의 릴레이로 구성됨을 특징으로 하는 전조등의 자동절환장치가 제공된다.According to the present invention for achieving the above object, a light sensing sensor for sensing the headlight light of the opposite vehicle by the power is applied by the headlight switch operated by the driver, the power is simultaneously supplied with the light sensor and the slope of the car A slope switch for detecting a back plate, a switch for selecting an automatic mode by an output signal of the light sensor and the slope sensor, and a manual mode by a driver's operation, and the headlight switch in the manual mode of the switch Headlight control unit for controlling the switching supply of the output current by each signal output from the dimmer switch for selectively connecting the power applied through the power supply, and is connected to the output terminal of the headlight control unit to supply the current to the upper and lower lights It is provided with an automatic switching device of the headlamp, characterized in that each relay.

이하, 도면을 참조하여 본 발명의 바람직한 실시예를 더욱 구체적으로 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

제 2 도는 본 발명의 회로도이고, 제 3 도는 본 발명에 의한 경사로감지수단(20)의 실시예를 도시한 개략도이다.2 is a circuit diagram of the present invention, and FIG. 3 is a schematic diagram showing an embodiment of the ramp detecting means 20 according to the present invention.

제 2 도에 도시한 바와같이, 대향차량의 전조등 빛에 의해 통전되는 광감지센서(10)와, 차의 경사로 등판을 감지하는 경사로감지수단(20)과, 상기 광감지센서(10) 및 상기 경사로감지수단(20)에 의해 작동되는 자동모드 및 운전자에 의해 작동되는 수동모드를 선택하는 절환스위치(S3)와, 상기 절환스위치(S3)의 수동모드시 상향등(41) 또는 하향등(42)의 점등을 선택하는 디머스위치(S2)는 각각 상향등(41) 및 하향등(42)의 점등을 제어하는 전조등제어부(30)의 입력단에 각각 접속되고, 상기 전조등제어부(30)의 두 출력단은 각각 상향등(41) 및 하향등(42)으로 전류를 공급하는 두 릴레이(K2,K3)에 접속된다.As shown in FIG. 2, the light detecting sensor 10 which is energized by the headlamp light of the opposite vehicle, the ramp detecting means 20 for detecting the ramp of the car, the light detecting sensor 10 and the A switching switch S3 for selecting an automatic mode operated by the inclination detecting means 20 and a manual mode operated by a driver; and an uplight 41 or a downlight 42 in the manual mode of the switching switch S3. The dimmer switch S2 for selecting the lighting of the lights is connected to the input terminals of the headlight control unit 30 for controlling the lighting of the uplight 41 and the downlight 42, respectively, and the two output terminals of the headlight control unit 30 are connected to each other. It is connected to two relays K2 and K3 which supply current to the upper lamp 41 and the lower lamp 42, respectively.

또, 상기 절환스위치(S3)의 수동조작시에 사용되는 상기 디머스위치(S2)는 전조등스위치(S1)의 후단에 접속되어 구성된다.The dimmer switch S2 used in the manual operation of the switching switch S3 is connected to the rear end of the headlight switch S1.

또, 상기 광감지센서(10)는 대향차량의 전조등 빛이 비추이는 자동차의 전방부에 설치하되, 본 발명이 적용된 자동차의 등화가 조사되지 않는 곳에 설치하여 자차의 빛은 감지하지 않도록 하는 것이 바람직하다.In addition, the light sensor 10 is installed on the front of the vehicle in which the headlights of the opposite vehicle is shining, it is preferable to install in a place where the equalization of the vehicle to which the present invention is applied does not detect the light of the own vehicle. Do.

또, 상기 경사로감지수단(20)은 대향차간에 서로 경사로 등판시에 상대차량의 불빛을 감지하지 못하여 전조등(40)이 계속 상향등(41)으로 조사되는 것을 방지하기 위해 설치된 것으로, 제 3 도에 도시한 바와같이, 평행하게 물이 담긴 밀폐된 수조(21)가 차의 전후방을 향하도록 차체에 부착되고, 상기 수조(21)내에 일측에 물의 부력에 의해 상승하는 뜨개(22)가 설치되고, 이 뜨개(22)의 승강작용에 의해 단속되도록 상기 뜨개(22)에 접점스위치(S4)가 결합되어, 자동차가 경사로를 등판하면 상기 접점스위치(S4)가 온상태가 되도록 구성된다.In addition, the inclined path detecting means 20 is installed to prevent the headlamp 40 from continuously being irradiated with the uplight 41 by not detecting the lights of the relative vehicles at the time of climbing the slope between the opposite cars. As shown, a closed water tank 21 containing water in parallel is attached to the vehicle body so as to face the front and rear of the car, and a float 22 is installed in one side of the water tank 21 by the buoyancy of water. The contact switch S4 is coupled to the knit 22 so as to be interrupted by the lifting and lowering action of the knit 22, so that the contact switch S4 is turned on when the vehicle climbs a slope.

또한 상기 전조등제어부(30)는 제 2 도에서 도시한 바와같이 상기 광감지센서(10) 및 상기 경사로감지수단(20)의 출력단이 낸드게이트(G1)회로의 입력단에 접속되고, 상기 낸드게이트(G1)회로의 출력단은 릴레이(K1)에 구비된 하나의 가동접점(Ka)의 일측에 접속되고, 상기 낸드게이트(G1)의 출력단에 병렬로 낫게이트(G2)를 통해 릴레이(K1)의 다른 가동접점(Kb)의 일측에 접속되고, 상기 릴레이(K)를 이루는 두 가동접점(Ka,Kb)의 타측은 상기 디머스위치(S2)의 양단에 각각 접속되고, 이 릴레이(K1)의 코일(Kc)은 두 가동접점(Ka,Kb)의 후단은 바이어스저항(R1,R2)을 통해 각각 두 트랜지스터(TR1,TR2)의 에미터측에 접속되어 이루어진다.In addition, as shown in FIG. 2, the headlight control unit 30 has an output terminal of the optical sensor 10 and the slope detecting means 20 connected to an input terminal of a NAND gate G1 circuit, and the NAND gate ( The output terminal of the G1) circuit is connected to one side of one movable contact Ka provided in the relay K1, and the other end of the relay K1 is connected to the output terminal of the NAND gate G1 in parallel to the output terminal of the NAND gate G1. It is connected to one side of the movable contact Kb, and the other sides of the two movable contacts Ka and Kb constituting the relay K are connected to both ends of the dimmer switch S2, respectively, and the coil of the relay K1. Kc is formed by connecting the rear ends of the two movable contacts Ka and Kb to the emitter side of the two transistors TR1 and TR2 through the bias resistors R1 and R2, respectively.

이와같이 구성된 본 발명은 절환스위치(S3)를 자동으로 하였을 때에는, 경사로등판을 제외한 모든 야간주행시에 마주오는 대향차량의 불빛이 감지되면 전조등(40)을 하향등(42)으로, 그리고 마주오는 차량이 없을 때는 전조등(40)을 상향등(41)으로 점등하게 된다.According to the present invention configured as described above, when the switching switch S3 is automatically performed, when the lights of the opposite vehicles are detected at all night driving except for the ramp, the headlamp 40 is turned into the downlight 42, and the oncoming vehicle is When there is no headlight 40 is turned on by the high beam (41).

예를 들어, 경사로 하강중 또는 평지주행시 대향차량의 불빛이 감지되지 않는 다면, 광감지센서(10)와 경사로감지수단(20)의 접점스위치(S4)에서 각각 로우레벨의 신호가 낸드게이트(G1)의 입력단으로 인가되고, 이 낸드게이트(G1)의 출력단에는 하이레벨의 신호가 출력되어 릴레이(K1)의 가동접점(Ka)과 바이어스저항(R1)을 통해 트랜지스터(TR1)를 터언시키면 릴레이(K2)는 작동되어 상향등(41)을 점등시키게 되며, 낫게이트(G2)를 통해 출력된 로우레벨의 신호에 의하여 트랜지스터(TR2)는 오프되어 하향등(42)은 소등하게 된다.For example, if the light of the opposite vehicle is not detected during the descent or flat driving, the low level signal is respectively applied to the NAND gate G1 at the contact switch S4 of the light sensor 10 and the slope detection means 20. Is applied to the input terminal of the NAND gate G1, and a high level signal is output to the output terminal of the NAND gate G1, and the transistor TR1 is turned on through the movable contact Ka and the bias resistor R1 of the relay K1. K2 is activated to turn on the upper lamp 41, and the transistor TR2 is turned off by the low level signal output through the knock gate G2, and the lower lamp 42 is turned off.

이와같이 상향등(41)이 점등되어 주행중에 대향차량의 불빛이 감지되면 광감지센서(10)의 출력은 하이레벨의 신호로 변동되어 낸드게이트(G1)의 입력단으로 인가되고, 이 낸드게이트(G1)의 출력단에는 로우레벨의 신호가 출력되어 바이어스저항(R1)을 통해 트랜지스터(TR1)를 턴오프시킨다. 이에 따라 릴레이(K1)는 작동하지 않게 되어 상향등(41)을 소등하게 낫고, 낫게이트(G2)를 통해 출력된 하이레벨의 신호에 의하여 트랜지스터(TR2)는 턴온되며 릴레이(K2)를 작동시켜 하향등(42)을 점등하게 된다.As such, when the high light 41 is turned on and the light of the opposite vehicle is detected while driving, the output of the light sensor 10 is changed to a high level signal and applied to the input terminal of the NAND gate G1, and the NAND gate G1 is applied. A low level signal is output to the output terminal of the transistor TR1 through the bias resistor R1. Accordingly, the relay K1 does not operate so that the upper lamp 41 is lightly turned off, and the transistor TR2 is turned on by the high level signal outputted through the sickle gate G2, and the relay K2 is operated to move downward. The lamp 42 is turned on.

이와같이 절환스위치(S3)를 자동모드로 선택하였을 때는 디머스위치(S2)의 작동에 의하지 않고 자동으로 작동되지만, 절환스위치(S3)를 수동모드로 하였을때에는 상기 릴레이(K1)의 두 가동접점(Ka,Kb)이 절환접속되므로 디머스위치(S2)의 작동에 의하여 두 트랜지스터(TR1,TR2)의 통전을 제어하므로 운전자의 임의조작에 의하여 전조등(40)의 조사각을 조작할 수 있게된다.In this way, when the switching switch (S3) is selected as the automatic mode, it is automatically operated without the operation of the dimmer switch (S2) .However, when the switching switch (S3) is set to the manual mode, the two movable contacts of the relay (K1) ( Since Ka and Kb are switched, the energization of the two transistors TR1 and TR2 is controlled by the operation of the dimmer switch S2, so that the irradiation angle of the headlamp 40 can be manipulated by the driver's arbitrary operation.
