Description
본 발명은 자동차에 설치되는 밧데리(Battery)의 방전을 방지하기 위한 장치에 대한 것으로, 더욱 상세하게는 등화장치가 점등된 상태에서 엔진시동을 끈 상태로 방치했을 경우 타이머장치가 작동하여 등화 장치를 자동소등시켜줌으로써 밧데리의 완전방전을 예방할 수 있도록 한 자동차 밧데리의 방전방지장치에 관한 것이다.The present invention relates to a device for preventing discharge of a battery (battery) installed in a vehicle, and more particularly, when the engine device is turned off while the light is turned on, the timer device operates to operate the light device. The present invention relates to a vehicle battery discharge preventing device that is capable of preventing complete discharge of a battery by automatically turning off the lamp.
일반적으로 자동차에 설치되는 밧데리는 발전기와 함께 자동차의 전기장치를 작동케하는 중요한 역할을 맞고 있으며, 특히 밧데리는 기관이 정지하고 있거나 엔진시동을 걸 때 전원을 공급하게 되므로 항시 밧데리에는 충분한 전원이 충전되어 있어야만 한다.In general, batteries installed in automobiles play an important role in operating the vehicle's electric devices together with generators. Especially, batteries are supplied with sufficient power when the engine is stopped or when the engine is started. It must be
한편, 자동차에는 등화장치가 설치되어 조명기능과 신호기능을 수행하게 되는데 이 등화장치는 발전기의 전원뿐만 아니라 엔진시동이 꺼진 상태에서의 순수밧데리 전원만에 의해서도 점등되도록 설계되어 있다.On the other hand, the car is equipped with a lighting device to perform a lighting function and a signal function, which is designed to be turned on not only the power of the generator but also the pure battery power in the engine start-off state.
즉 사용상의 편의를 위해 밧데리 전원에 의해 점등이 되도록 설계되어 있는 것이다.That is, it is designed to be turned on by the battery power source for convenience of use.
따라서, 운전자가 미등이나 전조등 등을 켜둔채 장시간 주차(엔진시동이 꺼진상태)를 해놓게 되면 밧데리의 전원이 모두 방전되어버려 엔진시동을 걸 수 없게 되는 어려움을 격게 될 것임은 당연한 이치다 할 것이다.Therefore, if the driver parks for a long time with the taillights or the headlights turned on (engine startup is turned off), it will be natural that the battery will be discharged and the engine will not be able to start.
제1도는 종래의 일반자동차에 있어서 밧데리전원에 의해 구동되는 등화장치와 밧데리와의 연결상태를 예시한 것으로, BAT는 밧데리를 나타내며, SWU는 밧데리(BAT)의 전원을 단속하는 스위치유니트를 나타내고, ALT는 발전기를 나타내며, HL은 전조등, TNS 는 미등, RL은 실내등류를 나타낸다.1 is a view illustrating a connection state between a battery and an equalizer driven by a battery power source in a conventional general vehicle, BAT represents a battery, and SWU represents a switch unit for intercepting a battery (BAT) power source. ALT stands for generator, HL stands for headlight, TNS stands for taillight, and RL stands for room lamp.
이와같이 종래 등화장치 전기회로구성은 스위치유니트(SWU)를 통해 바로 밧데리(BAT)의 전원이 각각의 램프류에 공급되도록 설계되어 있는 관계로 운전자가 실수로 전조등(HL)이나 미등(TNS)을 켜놓은채 시동을 끈 상태로 장시간 방치해 놓을 경우 밧데리(BAT)가 방전되어 재충전을 해야 하는 경우가 종종 있었다.As such, the electric circuit configuration of the conventional lighting device is designed so that the power of the battery BAT is directly supplied to each lamp through the switch unit. Therefore, the driver accidentally turns on the headlight (HL) or the taillight (TNS). If left unattended for a long time, the battery was often discharged and required to be recharged.
한편, 최근에는 이러한 밧데리(BAT)의 방전문제를 해결하고자 전조등이나 미등을 켜둔채 하차를 하면 경보음이 울리도록 하는 방전예방 경보장치가 어느정도의 밧데리방전 예방효과를 거두고 있는 실정이다.On the other hand, in recent years, to prevent the discharge problem of the battery (BAT) to get off with the headlights or taillights, the discharge prevention alarm device that the alarm sounds so that the discharge of a certain amount of battery discharge prevention effect.
전술한 바와 같이 반전방지장치가 구비되지 아니한 일반자동차에 있어서는 운전자가 자칫 실수를 하여 전조등(HL)이나 미등(TNS)이나 켜둔채 장시간 방치했을 경우 점등된 전조등이나 미등을 자동소등할 수 있는 장치가 없기 때문에 어쩔 수 없이 밧데리방전사고를 당하게 되는 문제점이 있었으며, 방전예방경보장치를 구비한 차량의 경우에는 주위가 조용하고 운전자가 침착한 경우에는 어느정도의 효과를 거둘 수 있었으나, 비오는날과 같이 주위가 시끄럽고 급히 하차하게 되는 경우에는 운전자가 경보음을 제대로 들을 수가 없어 경보음이 울렸음에도 불구하고 전조등이나 미등을 끄지않고 그냥 하차해버리는 예가 많아 밧데리의 방전사고를 완전히 예방하는 데에는 다소 미흡한 점이 있었다.As described above, in a general vehicle that is not equipped with an anti-reversing device, a device capable of automatically turning off a lit headlight or taillight when the driver makes a mistake by leaving the headlight (HL) or the tail light (TNS) for a long time. There was a problem in that the battery discharge accident was inevitable, and in the case of a vehicle equipped with a discharge prevention warning device, the surroundings were quiet and the driver had a certain effect. In case of getting off quickly and suddenly, the driver could not hear the alarm sound properly, but despite the alarm sounding, there are many cases of getting off without turning off the headlights or taillights.
따라서, 본 발명에서는 상기와 같은 제반문제점을 감안하여 밧데리와 등화장치의 사이에 타이머 제어유니트를 설치함으로써 운전자가 실수로 등화장치를 켜둔채 하차를 하더라도 일정시간이 경화하면 제어유니트의 제어동작으로 점등상태의 등화장치를 자동소등시켜 주로록 하여 밧데리의 완전방전을 막아 차량의 효과적인 운행관리가 이루어질 수 있도록 하는데 그 목적이 있는 것이다.Therefore, in the present invention, in consideration of the above problems, by installing a timer control unit between the battery and the lighting device, even if the driver accidentally gets off with the lighting device turned on, if a certain amount of time is hardened, the control operation of the control unit turns on. The purpose of the present invention is to automatically turn off the lighting device in the state so that the battery can be discharged effectively and the vehicle can be effectively managed.

또한, 시동정지감지수단(1')으로써 점화스위치의 오프(OFF)상태를 감지하기 위한 점화스위치감지센서(KS-S)가 점화스위치에 연결설치되어 있다.In addition, an ignition switch detection sensor KS-S for detecting the OFF state of the ignition switch is connected to the ignition switch as the start stop detection means 1 '.
상기 감지센서(TNS-S)가 점화스위치에 연결설치되어 있다.The sensor TNS-S is connected to the ignition switch.
상기 감지센서(TNS-S)와 전조등감지센서(HL-S)는 타이머제어유니트(2)를 구성하는 앤드게이트(AND1)(AND2)의 일측 입력으로 각각 연결되고 있으며, 점화스위치감지센서(KS-S)는 동 앤드게이트(AND1)(AND2)의 타측임력으로 연결되는 구성을 하고 있으며, 상기 앤드게이트(AND1)(AND2)의 각 출력은 타이머제어유니트(2)내에 설치된 타이머(T)의 입력에 연결되어 있다.The detection sensor TNS-S and the headlight detection sensor HL-S are connected to one input of an AND gate AND1 AND2 constituting the timer control unit 2, respectively, and an ignition switch detection sensor KS. -S is connected to the other force of the AND gate AND1 and AND2, and each output of the AND gate AND1 AND2 is connected to the timer T installed in the timer control unit 2. It is connected to the input.
이 타이머(T)의 출력은 밧데리전원차단유니트(3)를 구성하는 릴레이(RY)의 코일(C)에 연결되어지며, 이 릴레이(RY)의 단자(a)는 자동차밧데리(BAT)와 스위치유니트(4)를 구성하는 일부인 콤비스위치(C-SW)의 공통단자(CT)에 연결되어 있으며 이 콤비스위치(C-SW)의 미등단자(TT)에는 미등(TNS)이 전조등단자(HL)에는 전조등(HL)이 연결되어 있다.The output of the timer T is connected to the coil C of the relay RY constituting the battery power cut-off unit 3, and the terminal a of the relay RY is connected to the vehicle battery BAT and the switch. It is connected to the common terminal (CT) of the combination switch (C-SW), which is a part of the unit (4), and the tail light (TNS) is the headlight terminal (HL) of the tail light terminal (TT) of the combination switch (C-SW). Is connected to a headlight (HL).
이와같은 구성을 보이는 본 발명은 제4도의 제어흐름도를 참조로 그 작용을 설명하면, 먼저 램프점등감지수단(1)인 미등감지센서(TNS-S)와 전조등 감지센서(HL-S)에서 미등(TNS)과 전조등(HL)의 점등상태가 감지되고, 동시에 시동정지감지수단(1')인 점화스위치감지센서(KS-S)에서 엔진시동의 정지(꺼짐)상태가 감지되어 타이머제어유니트(2)로 인가하게 된다. 그러한 타이머제어유니트(2)에서 미등(TNS)과 헤드램프(HL)가 점등상태인지와 엔진시동이 꺼진 상태인지를 판단하게 된다.The present invention showing such a configuration will be described with reference to the control flow diagram of FIG. 4, first, the taillight detection sensor (TNS-S) and the headlight detection sensor (HL-S) The lighting state of TNS and the headlight HL is sensed, and at the same time, the ignition switch detection sensor KS-S, which is the start stop detection means 1 ', detects the engine start stop (off) state. 2). In the timer control unit 2, it is determined whether the tail lights TNS and the head lamp HL are turned on and the engine is turned off.
즉, 램프점등감지수단(1)과, 시동정지감지수단(1')을 통해 감지된 감지신호는 타이머제어유니트(2)를 구성하는 앤드게이트(AND1)(AND2)의 입력조건을 만족하게 되므로 앤드게이트(AND1)(AND2)가 도통되어 신호가 타이머(T)에 유가됨으로써 타이머(T)가 가동되어 카운트(예 ; 1~2시간)를 시작하게 된다. 따라서 정해진 카운트 값(시간)에 이르면 전원이 타이머(T)를 통해 밧데리전원차단유니트(3)를 구성하는 릴레이(RY)의 코일(C)을 통해 흐르게 되므로 자력이 형성되어 동릴레이단자(a)를 오픈(OPEN)시키게 된다.That is, the detection signal detected through the lamp lighting detecting means 1 and the start stop detecting means 1 'satisfies the input conditions of the AND gate AND1 AND2 constituting the timer control unit 2. The AND gate AND1 (AND2) is turned on so that the signal is brought to the timer T so that the timer T is activated to start a count (for example, 1 to 2 hours). Therefore, when the predetermined count value (time) is reached, the power flows through the coil C of the relay RY constituting the battery power cut-off unit 3 through the timer T, so that a magnetic force is formed, and thus the relay terminal (a). OPEN will be opened.
그러므로 밧데리(BAT)에서 콤비스위치(C-SW)를 거쳐 충전장치(5)를 구성하는 미등(TNS)이나 전조등(HL)으로 공급된 전원이 차단되어 미등(TNS)과 전조등(HL)은 바로 자동소등되게 되는 것이다. 즉 적절한 타이머(T)값의 설정하게 되면 밧데리(BAT)가 완전방전되기 이전인 스타트모터가 구동될 수 있는 시점에서 충전장치의 자동소등이 이루어지도록 할 수가 있는 것이다.Therefore, the power supplied from the battery (BAT) to the tail light (TNS) or the headlight (HL) constituting the charging device (5) via the combination switch (C-SW) is cut off, so the tail light (TNS) and the headlight (HL) It will be turned off automatically. In other words, if the appropriate timer T is set, the charging device can be automatically turned off at the time when the start motor can be driven before the battery BAT is fully discharged.
한편, 점화스위치가 켜진상태에서는 엔진시동의 정지상태가 감지되지 않게 되므로 앤드게이트(AND1)(AND2)가 불통되어 충전장치(5)에는 전혀 영향을 미치지 않게 된다.On the other hand, since the stop state of the engine start is not detected when the ignition switch is turned on, the AND gates AND1 and AND2 are turned off so that the charging device 5 is not affected at all.
이와같이 본 발명에 의하면, 밧데리와 등화장치의 사이에 타이머제어유니트(2)를 매개시켜 설치함과 동시에 램프점등감지수단(1)과, 시동정지감지수단(1')을 설치하여 운전자가 실수로 등화장치를 켜둔채 하차를 하더라도 일정시간이 경과하면 밧데리의 완전방전이 되기전(스타트모터가 구동가능하도록)에 충전장치를 자동소등동 시킴으로써 밧데리의 완전방전을 미연에 방비할 수가 있는 것이며 따라서, 방전사고로 인한 차량의 견인아니 재충전 등의 고생(수고)을 하지 않게 되는 것이며, 나아가 차량의 효율적인 운행관리를 가능케하는 효과를 제공하게 되는 것이다.As described above, according to the present invention, the timer control unit 2 is installed between the battery and the equalizer, and the lamp lighting detecting means 1 and the starting stop detecting means 1 'are installed. Even if you get off with the lights on, you can prevent the battery from fully discharged by automatically turning off the charging device before the battery is fully discharged (so that the start motor can be driven). It will not cause the trouble (trouble) such as towing or recharging of the vehicle due to the discharge accident, and further provide the effect of enabling efficient operation management of the vehicle.
이상에서 설명한 것은 본 발명의 자동차밧데리의 방전방지장치를 실시하기 위한 하나의 일실시예에 불과한 것이며, 본 발명은 상기한 실시예에 한정되지 않고, 다음의 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진자라면 누구든지 다양한 변경실시가 가능할 것이다.What has been described above is just one embodiment for implementing the discharge preventing device of the vehicle battery of the present invention, the present invention is not limited to the above-described embodiment, the gist of the invention claimed in the following claims Various changes can be made by those skilled in the art without departing from the scope of the present invention.
