Description
본 고안은 자동차용 전조등에 관한 것으로, 특히 야간에 자동차가 주행중일 때에는 전조등이 점등되고, 자동차가 정차될 때에는 전조등이 소등되도록 하는 자동차용 전조등 온/오프장치에 관한 것이다.The present invention relates to a headlamp for an automobile, and more particularly, to a headlight on / off device for a vehicle such that the headlight is turned on when the car is running at night, the headlight is turned off when the vehicle is stopped.
자동차의 등화장치로 자동차의 전면일측에 장착된 전조등은 야간에 안전한 주행을 위하여 전방을 조명하는 램프로서 전방의 시야를 확보하기 위한 것이다. 전조등은 일정의 조건을 가지고 있는데, 이러한 조건은 야간에 전방을 조명할 때에 일정거리의 대상물을 식별할 수 있어야 하고, 어느 정도의 빛확산으로 주위의 상태를 용이하게 파악할 수 있어야 하며, 교행시나 주행시에 적정한 광도 및 조사각을 가져야 하고, 승차인원이나 탑재하중에 의해 광축이나 조명효과가 저하되지 않아야 한다.Headlights mounted on one side of the front of the vehicle as the equalizer of the vehicle is to secure the front view as a lamp for illuminating the front for safe driving at night. Headlights have a certain condition, which must be able to identify objects at a certain distance when illuminating the front at night, and be able to easily grasp the surrounding conditions with a certain amount of light diffusion. It should have proper brightness and irradiation angle, and the optical axis or lighting effect should not be degraded by the number of passengers or payload.
이와 같이 자동차의 전조등은 주행시나 교행시에 광도 및 조사각도가 다르다. 즉, 주행시는 운전자의 시야확보를 위하여 다소 원거리까지 조사하여야 하고, 자동차가 서로 교행시에는 상대운전자를 위하여 조사광도가 작고 조사각도도 햐향으로 향하도록 한다.As such, the headlights of automobiles differ in brightness and irradiation angle when driving or driving. In other words, when driving, the vehicle should be irradiated to a far distance in order to secure the driver's field of view, and when the cars cross each other, the irradiation brightness is small and the irradiation angle is directed toward the opposite driver.
종래의 전조등의 벌브내에 구성된 필라멘트의 구성은 주행용 필라멘트와 교행용 필라멘트가 벌브내에 같이 구성되어 있고, 운전자가 전조등을 상향 또는 하향으로 조작시에 주행용 필라멘트 및 교행용 필라멘트는 각각 자동차용 배터리의 전원으로 점등된다. 즉, 주행시에는 주행용 필라멘트에 전류가 흘러 점등되고, 교행시에는 교행용 필라멘트에 전류가 흘러 점등된다. 이는 필라멘트의 크기에 따라 전력소비량과 효율이 다르기 때문이다. 전조등은 필라멘트 광도위치로 상향 및 하향으로 조정할 수 있고, 전조등내의 반사각을 조정하여 조사각을 조정할 수도 있다.In the conventional filament bulbs, the filament for driving and the filament for driving are configured together in the bulb, and the driving filament and the traveling filament are respectively used when the driver operates the headlight upward or downward. Lights up with the power supply. That is, when running, a current flows through the running filament and lights up, and when traveling, a current flows through the running filament and lights up. This is because power consumption and efficiency vary depending on the size of the filament. The headlight can be adjusted upward and downward to the filament intensity position, and the irradiation angle can be adjusted by adjusting the reflection angle in the headlight.
이러한 종래의 전조등을 구동시키는 전기배선도는 도 1에서, 자동차내에 장착된 각종 램프를 점등 또는 소등시키는 라이트스위치(1)와, 상기 라이트스위치(1)의 2단접점에 코일부(2a)가 연결되어 코일부(2a)의 자력에 의해 배터리전원(B+)을 온 또는 오프시키는 릴레이스위치(2b)가 구성된 제 1릴레이(2)와, 상기 제 1릴레이(2)의 릴레이스위치(2b)에 연결되어 상향등(4c, 4d) 및 하향등(4a, 4b)의 점등 및 소등을 스위칭시키는 딤머스위치(3)가 구성된다.The electric wiring diagram for driving the conventional headlamp is shown in Figure 1, the light switch (1) for turning on or off the various lamps mounted in the vehicle, and the coil portion (2a) is connected to the two-stage contact of the light switch (1) And a relay switch 2b configured to turn on or off the battery power source B + by the magnetic force of the coil unit 2a, and is connected to the relay switch 2b of the first relay 2. Thus, a dimmer switch 3 is configured to switch on and off of the high beams 4c and 4d and the low beams 4a and 4b.
이러한 구성을 갖는 전조등의 전기배선도는 라이트스위치(1)를 1단, 2단 또는 오프단으로 절환시켜 전조등의 점등 및 소등을 절환시킨다. 라이트스위치(1)가 1단일 때에는 자동차내의 미등을 포함한 각종 조명등을 점소등시킬 수 있고, 라이트스위치(1)가 2단일 때에는 제 1릴레이(2)의 코일부(2a)에 배터리전원(B+)이 인가되어 코일부(2a)가 자화되어 릴레이스위치(2b)를 턴온시킨다. 이때, 릴레이스위치(2b)는 딤머스위치(3)에 연결되어 운전자의 조작에 의해 전조등이 상향등(4c, 4d) 또는 하향등(4a, 4b)으로 점소등된다.The electric wiring diagram of the headlamp having such a configuration switches the light switch 1 to the first stage, the second stage or the off stage to switch the headlight on and off. When the light switch 1 is in one stage, various lights such as taillights in the vehicle can be turned on and off, and when the light switch 1 is in two stages, the battery unit B + is supplied to the coil portion 2a of the first relay 2. This is applied to magnetize the coil portion 2a to turn on the relay switch 2b. At this time, the relay switch 2b is connected to the dimmer switch 3 so that the headlamps are turned on by the driver's manipulation as the high beams 4c and 4d or the low beams 4a and 4b.
이와 같이 종래에는 운전자가 야간에 자동차를 운행중에 정차후에 출발을 할 때에는 전조등을 상향 또는 하향으로 점등시킨 후에 출발을 하여야 하고, 횡단보다나 정차를 위하여 정지를 한 후에는 전조등을 소등시켜야 한다. 따라서, 교통정체가 심한 곳이나 횡단보도가 많은 시내 등에서 자동차를 주행중일 때에는 전조등을 점소등해야 하는 번거러움이 있었다. 또한, 초보운전자의 경우에는 미숙한 운전에다가 전조등을 점소등해야기 때문에 부주의로 인하여 안전사고를 일으킬 수 있는 위험이 내재되어 있었다.As described above, when the driver starts the vehicle after stopping at night, the driver should start the vehicle after turning the headlights upward or downward, and turn off the headlights after stopping the vehicle for stopping rather than crossing. Therefore, when driving a car in a place with heavy traffic or in a city with many crosswalks, the headlights have to be turned off. In addition, in the case of a novice driver, the headlights should be turned off in addition to immature driving, so there is a risk that a safety accident may be caused by carelessness.
본 고안은 상기와 같은 문제를 해결하기 위하여 안출한 것으로, 자동차가 출발을 할 때에 엔진회전수계가 자동차의 움직임을 감지하여 전조등을 자동으로 점등시키고, 자동차가 정지될 때에는 전조등을 소등시켜 안전운행을 도모시킨 자동차용 전조등 온/오프장치를 제공하기 위한 것이 목적이다.The present invention was devised to solve the above problems, and when the vehicle starts, the engine tachometer detects the movement of the vehicle and automatically turns on the headlights, and turns off the headlights when the vehicle is stopped to ensure safe driving. An object of the present invention is to provide a headlight on / off device for automobiles.

본 고안은 상기의 목적을 달성하기 위하여, 라이트스위치의 2단위치에 연결되어 2단위치를 통해 인가되는 배터리전원에 의해 자회되는 코일부와, 상기 코일부와 근접되게 구성되어 코일부의 자기장에 의해 인가된 배터리전원을 딤머스위치로 스위칭시키는 릴레이스위치로 이루어진 릴레이와; 상기 코일부의 일단에 연결되어 엔진의 일정회전수를 감지하여 코일부로 인가되는 배터리전원을 도통 또는 차단시키는 엔진회전수계를 포함하여 이루어진 것이 특징이다.In order to achieve the above object, the present invention is connected to the second stage position of the light switch, the coil portion is rotated by the battery power applied through the two unit value, and is configured to be close to the coil portion by the magnetic field of the coil portion A relay comprising a relay switch for switching the applied battery power to a dimmer switch; It is characterized in that it comprises an engine rotation meter connected to one end of the coil portion to detect the constant rotational speed of the engine to conduct or cut off the battery power applied to the coil portion.
이하, 첨부된 도면에 의거하여 본 고안에 관한 자동차용 전조등 온/오프장치를 살펴보면 다음과 같다.Hereinafter, the headlight on / off device for an automobile according to the present invention will be described based on the accompanying drawings.
도 2는 본 고안의 전조등 온/오프장치의 전기배선도이다.Figure 2 is an electrical wiring diagram of the headlight on / off device of the present invention.
라이트스위치(10)는 운전석의 전면에 구성된 조향핸들의 일측에 장착된 것으로, 자동차에 장착된 각종 램프류를 점등 또는 소등시킨다. 라이트스위치(10)를 1단으로 절환시키면, 자동차용 미등 및 차폭등 등이 점등되고, 2단으로 절환시키면, 전조등이 점등된다.The light switch 10 is mounted on one side of the steering wheel configured on the front of the driver's seat, and turns on or off various lamps mounted on the vehicle. When the light switch 10 is switched to the first stage, the tail light for the vehicle, the vehicle width lamp, etc. are turned on, and when the switch is switched to the second stage, the headlight is turned on.
릴레이(20)는 상기 라이트스위치(10)의 2단접점에 코일부(21)가 연결되고, 코일부(21)에 대응되게 릴레이스위치(22)가 구성된다. 라이트스위치(10)가 2단으로 절환되어 있을 때에 배터리전원(B+)이 코일부(21)로 도통되어 자기장이 발생되고, 코일부(21)의 자기장에 의해 릴레이스위치(22)가 배터리전원(B+)을 스위칭시킨다.In the relay 20, the coil part 21 is connected to the second stage contact point of the light switch 10, and the relay switch 22 is configured to correspond to the coil part 21. When the light switch 10 is switched in two stages, the battery power source B + is conducted to the coil unit 21 to generate a magnetic field. The magnetic field of the coil unit 21 causes the relay switch 22 to generate a battery power source ( Switch B +).
딤머스위치(26)는 상기 라이트스위치(10)와 일체로 구성되어 상기 릴레이스위치(22)를 통해 인가된 배터리전원(B+)을 절환시켜 전조등(30-33)을 상향 및 하향으로 점소등시킨다.The dimmer switch 26 is integrally formed with the light switch 10 so as to switch the battery power B + applied through the relay switch 22 to turn the headlamps 30-33 upward and downward. .
엔진회전수계(24)는 엔진의 회전상태를 가시적인 수치로 표시하는 것으로, 엔진이 공회전할 때에는 RPM이 약 700-800회정도이고, 자동차가 구동중일 때에는 RPM이 약 1,000-1,200회전가 된다. 이때, 엔진회전수계는 RPM이 약 1,000-1,200회정도가 온되어 인가되는 배터리전원(B+)을 도통시킨다. 즉, 최소한 엔진의 회전수가 1,000이하가 되면, 자동차가 움지이지 않는 것으로 간주하여 인가되는 배터리전원(B+)을 차단시킨다.The engine tachometer 24 displays the rotational state of the engine as a visible value. When the engine is idling, the RPM is about 700-800 times, and when the vehicle is being driven, the RPM is about 1,000-1,200 revolutions. At this time, the engine rotational water is turned on about 1,000-1,200 times the RPM to turn on the battery power (B +) is applied. That is, if the engine speed is at least 1,000 or less, the vehicle is regarded as not moving and the battery power B + applied is cut off.
이와 같이 구성된 본 고안에 관한 자동차용 전조등 온/오프장치의 작용을 상세하게 설명한다.The operation of the headlight on / off device for a vehicle according to the present invention configured as described above will be described in detail.
운전자가 야간에 자동차를 운행중일 때에는 라이트스위치(10)를 2단위치로 절환시킨 상태에서 딤머스위치(26)를 조작시켜 전조등(30-33)을 상향 또는 하향으로 조절시킨다. 이때, 자동차가 주행중일 때에는 엔진의 회전수는 일정의 회전수이상이므로, 엔진회전수계(24)는 온상태가 되고, 라이트스위치(10)의 2단위치에 연결된 릴레이(20)의 코일부(21)는 인가되는 배터리전원(B+)에 의해 도통상태가 되어 자화된다. 코일부(21)의 자화는 근접된 릴레이스위치(22)를 온시켜 배터리전원(B+)이 딤머스위치(26)를 통해 전조등(30-33)으로 인가되도록하여 전조등(30-33)을 점등시킨다. 즉, 자동차의 운전자가 라이트스위치(10)를 온시킨 상태에서는 자동차가 구동되어 움직임이 있어야 전조등(30-33)이 점등되도록 한 것이다.When the driver is driving the car at night, the dimmer switch 26 is operated while the light switch 10 is switched to the second position to adjust the headlamps 30 to 33 upward or downward. At this time, since the engine speed is more than a predetermined speed while the vehicle is running, the engine tachometer 24 is turned on, and the coil part of the relay 20 connected to the second stage position of the light switch 10 ( 21 is energized by the applied battery power source B + and magnetized. The magnetization of the coil unit 21 turns on the adjacent relay switch 22 so that the battery power source B + is applied to the headlamps 30-33 through the dimmer switch 26 to light the headlamps 30-33. Let's do it. That is, when the driver of the vehicle turns on the light switch 10, the headlights 30 to 33 are turned on only when the vehicle is driven and there is movement.
또한, 자동차를 운행중에 횡단보도나 급정거 등에 의해 브레이크페달을 밟아 정차를 하게 되면, 엔진회전수는 급격히 저하되고, 따라서, 엔진회전수계(24)는 릴레이(20)의 코일부(21)를 통해 인가되는 배터리전원(B+)을 차단시켜 코일부(21)의 자화상태를 오프시킴으로, 코일부(21)에 의해 릴레이스위치(22)는 오프상태가 된다. 따라서, 딤머스위치(26)로는 배터리전원(B+)이 인가되지 않아 전조등(30-33)이 자동으로 소등된다.In addition, when the vehicle stops by stepping on the brake pedal by pedestrian crossing or sudden stop while driving, the engine speed decreases rapidly, and therefore, the engine speed meter 24 is passed through the coil portion 21 of the relay 20. The magnetization state of the coil unit 21 is turned off by cutting off the battery power source B + applied, whereby the relay switch 22 is turned off by the coil unit 21. Therefore, battery power B + is not applied to the dimmer switch 26, so the headlamps 30-33 are automatically turned off.
그러나, 전조등(30-33)을 강제적으로 점등시킬 필요가 있을 때에는 딤머스위치(26)에 별도로 연결된 배터리전원(B+)으로 전조등(30-33)을 점등시킬 수 있다.However, when it is necessary to forcibly turn on the headlamps 30-33, the headlamps 30-33 can be turned on by the battery power source B + connected to the dimmer switch 26 separately.
이와 같이 야간에 자동차를 운행할 때에 라이트스위치(10)를 2단위치로 온시킨 상태에서는 엔진회전수계(24)에서 일정회전수이상을 감지하면, 릴레이(20)의 코일부(21)를 자화시켜 릴레이스위치(22)를 온시키므로, 전조등(30-33)을 점등시키고, 자동차의 속도가 일정의 엔진회전수이하로 떨어지면, 엔진회전수계(24)의 작동으로 코일부(21) 및 릴레이스위치(22)를 오프시켜 전조등(30-33)을 자동으로 소등시킨다. 따라서, 미숙련된 자동차의 운전자에게 운전의 편의성을 제공한다.As such, when the light switch 10 is turned on to the second position while driving a car at night, the coil part 21 of the relay 20 is magnetized when the engine revolution counter 24 detects a predetermined rotation speed or more. Since the relay switch 22 is turned on, the headlights 30-33 are turned on, and when the speed of the vehicle falls below a predetermined engine speed, the coil part 21 and the relay switch are operated by the operation of the engine speedometer 24. (22) is turned off to turn off the headlights 30-33 automatically. Thus, the driver of an unskilled car is provided with the convenience of driving.
이상에서 설명한 바와 같이, 본 고안은 야간에 교통량이 많은 시내나 정체가 심한 고속도로 등에서 자동차를 운행할 때에 자동차의 주행여부에 따라 전조등이 자동으로 점등 또는 소등되도록 함으로써, 운전자의 불편을 해소시켜 운전피해를 최소화시켜 자동차의 운용에 편의성을 향상시킨 효과가 있다.As described above, the present invention is to prevent the driver's inconvenience by avoiding the inconvenience of the driver by automatically turning on or off the headlights depending on whether the vehicle is driven when driving the car at night or in heavy traffic such as a city with heavy traffic at night. By minimizing the efficiency of the operation of the car is improved.
