Description

열선에 의한 배터리 방전 방지장치Battery discharge prevention device by hot wire

본 고안은 열선에 의한 배터리 방전 방지장치에 관한 것이다.The present invention relates to a battery discharge preventing device by a hot wire.

보다 상세하게는 열선배드를 사용할 때 배터리의 전압을 감지하여 일정전압 이하로 전압이 감지될 경우에 경보음 발생과 함께 전원을 차단하여 배터리의 방전을 차단하는 열선에 의한 배터리 방전 방지장치에 관한 것이다.More specifically, the present invention relates to a battery discharge prevention device by heating wire that detects a voltage of a battery when a heating wire is used and cuts off the power by cutting off the power and alarm when a voltage is detected below a predetermined voltage. .

일반적으로 자동차에 백미러나 후단 유리창등에 빗물 또는 습기로 인하여 시야가 흐려지고, 동한기에 백미러나 유리창이 이슬이나 성에로 인하여 시야 관측이 불가능한 경우가 있다.In general, the visibility of the rear view mirror or rear window in the car is blurred due to rain or moisture, and in the winter, the rear view mirror or window may not be visible due to dew or frost.

이 문제를 해결하기 위하여 뒷유리창 또는 백미러등에 열선배드를 장착하여 전기적인 열을 가한다. 그러나 시동이 끄진 상태에서 장기간 열선배드를 사용하면 배터리는 방전이 계속되고, 심지어 완전 방전이 되면 시동이 걸리지 않게 된다.In order to solve this problem, electric heating is applied to the rear windshield or rearview mirror by mounting a heating bed. However, if you use the hot wire for a long time with the ignition off, the battery will continue to discharge, and even if fully discharged, the ignition will not start.

이 경우에 다른 차량의 충전된 배터리를 이용하여 시동을 걸거나 충전된 예비 배터리를 이용할 수밖에 없으므로 실제로 운행시 어려움을 많이 겪게된다.In this case, since it is necessary to start using a charged battery of another vehicle or use a spare battery charged, it is difficult to actually drive.

도 1은 종래의 자동차의 열선 장치에 관한 블록선도이다.1 is a block diagram of a conventional heating apparatus of a motor vehicle.

도 1에 도시된 바와 같이 차량에 전원을 공급하는 배터리(11)와, 배터리(11)와 연결되어 열선배드에 전원을 공급 및 차단하는 열선 스위치(12)와, 열선 스위치(12)에 의해 공급된 전원으로 열선에 전기적인 열이 발생하는 열선장치(13)로 구성된다.As shown in FIG. 1, a battery 11 for supplying power to a vehicle, a hot wire switch 12 connected to the battery 11 to supply and cut off power to the hot wire bed, and a hot wire switch 12 are supplied by the hot wire switch 12. It is composed of a heating device 13 for generating electrical heat to the heating wire with the power supply.

상기와 같이 구성된 종래의 자동차 열선장치는 운전자가 열선 스위치(12)를 온(on)하면 열선장치(13)에 전원이 공급되어 열선장치에 있는 코일이 전기적인 열을 발생시킨다.In the conventional automotive heating apparatus configured as described above, when a driver turns on the heating switch 12, power is supplied to the heating apparatus 13 so that a coil in the heating apparatus generates electrical heat.

시동이 꺼진 상태에서 운전자의 실수이든 아니든간에 열선 스위치를 오프(off)하지 않고 열선장치를 계속 사용하면 배터리(11)에서 전압이 계속적으로 방전된다.If the heating device is used continuously without turning off the heating switch, whether or not a driver's mistake is made, the voltage in the battery 11 is continuously discharged.

따라서, 방전된 배터리를 재충전하기 위해서는 운전자는 많은 불편함을 겪을 뿐만 아니라, 또한 한 번 방전된 배터리는 수명이 단축되고, 엔진 및 자동차의 성능이 저하되는 문제점이 있었다.Therefore, in order to recharge the discharged battery, the driver not only suffers a lot of inconvenience, but also, the battery once discharged has a problem of shortening the life and degrading the performance of the engine and the vehicle.

따라서 본 고안의 목적은 열선배드를 사용할 때 배터리의 전압을 감지하여 일정전압 이하로 전압이 감지될 경우에 경보음 발생과 함께 전원을 차단하여 배터리의 방전을 차단하는 열선에 의한 배터리 방전 방지장치를 제공하는 데 있다.Therefore, an object of the present invention is to detect a battery voltage when using a heating wire to prevent the battery discharge by the heating wire to cut off the battery by cutting off the power and alarm when the voltage is detected below a certain voltage To provide.

도 2는 본 고안의 열선에 의한 배터리 방전 방지장치에 관한 블록선도이다.Figure 2 is a block diagram of a battery discharge preventing device by a hot wire of the present invention.

도시된 바와 같이 차량에 전원을 공급하는 배터리(21)와, 배터리(21)와 연결되어 열선에 전원을 공급 및 차단하는 열선 스위치(22)와, 배터리(21) 및 열선 스위치(22)와 접속되며 배터리(21)의 전압을 감지하여 부저작동 및 릴레이 신호를 출력시키는 전압감지 회로부(23)와, 전압감지 회로부(23)와 접속되어 전압감지 회로부(23)의 출력신호에 의해 릴레이에 공급되는 전원을 차단시키는 릴레이(24)와, 릴레이(24)와 접속되고 접속된 릴레이(24)에 의해 전원을 공급받아 전기적인 열을 발생하는 열선장치(25)와, 상기 전압감지 회로부(23)의 출력신호에 의해 경보음을 발생시키는 경보장치(26)로 구성된다.As shown, a battery 21 for supplying power to the vehicle, a heating switch 22 connected to the battery 21 to supply and cut off power to the heating wire, and a battery 21 and the heating switch 22 are connected. And a voltage sensing circuit unit 23 which senses a voltage of the battery 21 and outputs a buzzer operation and a relay signal, and is connected to the voltage sensing circuit unit 23 and supplied to the relay by an output signal of the voltage sensing circuit unit 23. Of the relay 24 which cuts off the power supply, the heating wire device 25 which is supplied with power by the relay 24 connected to the relay 24 and generates electric heat, and the voltage sensing circuit unit 23. And an alarm device 26 for generating an alarm sound by the output signal.

또한, 상기 전압감지 회로부(23)는 배터리(21)의 현재 전압값을 측정하고, 측정값이 기준값 보다 작으면 릴레이신호 및 경보신호를 동시에 출력시키는 것을 특징으로 한다.In addition, the voltage sensing circuit unit 23 measures the current voltage value of the battery 21, and if the measured value is smaller than the reference value, it is characterized in that at the same time output the relay signal and the alarm signal.

또한, 상기 경보장치(26)는 청각으로 판단하는 부저(buzzer)나 알람(alarm)으로 할 수도 있고, 시각으로 판단하는 표시등이나 LED 표시기로 표시할 수 있다.In addition, the alarm device 26 may be a buzzer or an alarm that is determined by hearing, and may be displayed by an indicator or LED indicator that is determined by time.

상기와 같이 구성된 본 고안의 열선에 의한 배터리의 방전 방지장치를 설명하면 다음과 같다.Referring to the discharge prevention device of the battery by the heating wire of the present invention configured as described above are as follows.

즉, 운전자가 열선 스위치(22)를 온하면 열선 스위치(22)는 배터리(21)에 의해 전원을 공급받고, 그 전원은 릴레이(24)를 거쳐 열선장치(25)에 전기가 공급된다.That is, when the driver turns on the hot wire switch 22, the hot wire switch 22 is supplied with power by the battery 21, and the power is supplied to the hot wire device 25 via the relay 24.

열선장치(25)에 내장된 코일에 의해 열선장치(25)는 필요한 열을 얻는다. 그러나, 시동을 걸지 않은 상태에서 열선장치에 계속 열을 발생시키면 배터리는 충전은 되지 않고 방전만 되므로 배터리의 전압은 계속 낮아진다.The coil installed in the heating apparatus 25 obtains the necessary heat from the heating apparatus 25. However, if heat is continuously generated in the heating apparatus without starting, the battery is not charged but only discharged, and thus the voltage of the battery is continuously lowered.

배터리(21)는 일정전압 이하로 내려가면 시동이 걸리지 않을 뿐만 아니라 배터리로서의 기능을 하지 못하게 된다. 그러므로, 여러번의 시험을 통하여 배터리의 기능 및 시동이 걸리기 위한 최소의 전압값을 설정하여 기준값으로 정한다.When the battery 21 falls below a certain voltage, the battery 21 may not start and may not function as a battery. Therefore, the minimum voltage value for the battery's function and start-up is set as a reference value through several tests.

상기 전압감지 회로부(23)는 상기 기준값과 현재 배터리(21)의 측정값을 비교하는 정전압 비교회로를 갖도록 회로를 구성하고, 만약에 현재 배터리의 측정값이 기준값보다 작아지면 릴레이(24)에 공급되는 전원을 차단시키는 출력신호를 출력시킨다. 동시에 경보장치(26)에 경보음을 발생시키는 출력신호도 동시에 출력시킨다.The voltage sensing circuit unit 23 configures a circuit to have a constant voltage comparison circuit comparing the reference value with the measured value of the current battery 21, and if the measured value of the current battery is smaller than the reference value, the voltage is supplied to the relay 24. Outputs an output signal that cuts off the power supply. At the same time, an output signal for generating an alarm sound to the alarm device 26 is also output at the same time.

즉, 릴레이(24)에 공급되는 전원이 차단되므로 열선 스위치(22)는 온되어 있어도 열선장치(25)에는 전원이 공급되지 않으므로 배터리(21)의 전압은 방전되지 않게 되는 것이다.That is, since the power supplied to the relay 24 is cut off, even though the hot wire switch 22 is on, no power is supplied to the hot wire device 25, so that the voltage of the battery 21 is not discharged.

릴레이(24)가 차단되면서 동시에 경보장치(26)에도 출력신호가 입력되어 경보음을 발생시키므로 운전자는 경보음이 울릴 때에 열선 스위치(22)를 오프시키면 된다. 상기 경보장치(26)에는 청각으로 판단하는 부저(buzzer)나 알람(alarm)으로 할 수도 있고, 시각으로 판단하는 표시등이나 LED 표시기등의 여러 가지로 표시할 수 있다.Since the relay 24 is cut off and an output signal is also input to the alarm device 26 to generate an alarm sound, the driver may turn off the heating wire switch 22 when the alarm sound is sounded. The alarm device 26 may be an audible buzzer or an alarm, or may be displayed in various ways such as an indicator light or an LED indicator that is visually determined.

이상과 같이 구성되고 작용하는 본 고안에 의한 열선에 의한 배터리 방전 방지장치는 배터리의 전압을 감지하여 일정전압 이하로 전압이 감지될 경우에 경보음 발생과 함께 릴레이로 전원을 차단하여 배터리의 방전을 차단하므로써, 배터리가 방전되는 되는 것을 차단할 뿐만 아니라, 배터리의 수명 및 자동차의 성능이 저하되는 것을 보호하는 효과를 갖는다.Battery discharge prevention device by the heating wire according to the present invention is configured and acts as described above to detect the voltage of the battery and when the voltage is detected below a certain voltage, the alarm is generated and the power is cut off by the relay to discharge the battery By blocking, not only the battery is discharged, but also the battery life and the performance of the vehicle are reduced.
