본 고안은 경보기를 조작할 때 발생 하는 서지전압을 방지하여 주변회로에 영향을 미치지 않도록 한 자동차 경보기의 서지 방지회로에 관한 것이다.The present invention relates to a surge protection circuit of a car alarm that prevents the surge voltage generated when operating the alarm so as not to affect the peripheral circuit.
종래 장치는 제1도에 나타낸 바와 같이, 경보음을 발생시키는 경보기(10)와; 조향핸들의 중앙부에 위치하여 운전자가 조작하는 된 경보기 스위치(20)와; 상기 경보기 스위치(20)에 접속된 주 전원인 밧데리(30)로 이루어졌다.The conventional apparatus includes an alarm 10 for generating an alarm sound, as shown in FIG. 1; An alarm switch 20 positioned at the center of the steering wheel and operated by the driver; The battery 30 is a main power source connected to the alarm switch 20.
이러한 종래 장치는 운전자가 경보기 스위치(20)를 조작하므로써 발생하는 경보음으로 타 차량의 운전자나 보행자에게 주의를 줄 수 있다.Such a conventional device may give attention to a driver or a pedestrian of another vehicle by an alarm sound generated by a driver operating the alarm switch 20.
이와 같은 종래 장치는 제1도에 나타낸 바와 같이, 경보기 스위치(20)의 접점을 온 시키면 경보음이 발생하는데 경보기 스위치(20)의 조작시 접촉점에서 300 V의 서지전압, 즉 갑자기 크기가 변화하는 전압이 발생하게 되는데, 이러한 서지전압은 주 전원인 밧데리의 전압보다 상대적으로 크기 때문에 배터리와 연결되어 있는 타 회로에 영향을 미치게 된다.In the conventional apparatus, as shown in FIG. 1, when the contact point of the alarm switch 20 is turned on, an alarm sounds. However, when the alarm switch 20 is operated, a surge voltage of 300 V, i.e., suddenly, changes in magnitude at the contact point. Voltage is generated, and this surge voltage is relatively higher than the voltage of the main battery, which affects other circuits connected to the battery.
특히, 전자제어방식의 차량에 있어서 이러한 서지전압이 미치는 영향은 매우 크다.In particular, the influence of this surge voltage on the vehicle of the electronic control system is very large.
본 고안의 목적은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 경보기 스위치 조작시 발생하는 서지전압을 일정 이하로 하강시켜, 타 회로에 영향을 미치지 않게 하기 위한 경보기의 서지 방지회로를 제공하는 데 있다.An object of the present invention is to solve the conventional problems as described above, to provide a surge protection circuit for the alarm to lower the surge voltage generated during the operation of the alarm switch below a certain level, so as not to affect other circuits. have.
이하 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail.
본 고안 장치는 제2도에 나타낸 바와 같이, 경보음을 발생시키는 경보기(10)와; 조향핸들의 중앙부에 위치하여 운전자가 조작하는 된 경보기 스위치(20)와; 상기 경보기 스위치(20)에 접속된 주 전원인 밧데리(30)로 이루어진 경보기 회로에 있어서, 상기 밧데리(30)에 병렬접속되어 일정전압을 충전하는 콘덴서(C)와; 한쪽은 상기 콘덴서(C)와 밧데리(30)에 공통접속되고 다른 한쪽은 경보기 스위치(20)로 접속되는 저항(R)으로 구성함을 그 기술적 구성상의 특징으로 한다.The device of the present invention, as shown in Figure 2, the alarm 10 for generating an alarm sound; An alarm switch 20 positioned at the center of the steering wheel and operated by the driver; An alarm circuit comprising a battery (30) which is a main power source connected to the alarm switch (20), comprising: a capacitor (C) connected in parallel with the battery (30) to charge a predetermined voltage; The technical configuration is characterized in that one side is composed of a resistor (R) connected to the condenser (C) and the battery (30) and the other side is connected to the alarm switch (20).
이러한 본 고안 장치의 작용효과를 제2도를 참조하여 설명하면 다음과 같다.If described with reference to Figure 2 the effect of the device of the present invention.
밧데리(30)에 병렬접속된 콘덴서(C)는 경보기 스위치(20)가 접촉점에서 발생하는 서지전압을 충·방전할 수 있도록 되어있고, 한쪽은 상기 콘덴서(C)와 밧데리(30)에 공통접속되고 다른 한쪽은 경보기 스위치(20)로 접속되는 저항(R)은 경보기(10)로 유입되는 전압을 일정량 감소시킨다.The capacitor C connected in parallel with the battery 30 allows the alarm switch 20 to charge and discharge the surge voltage generated at the contact point, and one end is connected to the capacitor C and the battery 30 in common. On the other hand, the resistor R connected to the alarm switch 20 reduces the voltage flowing into the alarm 10 by a certain amount.
상기 콘덴서(C)는 서지전압이 발생 할 때에는 그 서지전압을 충전을 하고, 경보기 스위치(20)가 접속을 하면 방전을 하게 된다. 그러면, 경보기(10)로 유입되는 전압은 본래의 밧데리의 전압보다 크게 되는데, 이러한 유입전압을 저항(R)에서 하강시켜주므로서 경보기(10)에 영향을 미치지 않게 한다.The capacitor C charges the surge voltage when a surge voltage is generated, and discharges it when the alarm switch 20 is connected. Then, the voltage flowing into the alarm 10 becomes greater than the voltage of the original battery, so that the incoming voltage is lowered from the resistor R so as not to affect the alarm 10.
이러한 작용으로, 경보기 스위치(20)의 접촉시 발생하는 서지전압을 감소시킬 수 있어, 타회로에 영향을 미치지 않도록 한다.By this action, the surge voltage generated at the contact of the alarm switch 20 can be reduced, so as not to affect other circuits.
이상에서 살펴 본 바와 같이, 본 고안 장치는 경보기 스위치에서 발생하는 서지전압을 감소시킴으로서 타회로에 미치는 영향을 줄여줄 수 있는 유용한 것이다.As described above, the device of the present invention is useful to reduce the influence on other circuits by reducing the surge voltage generated in the alarm switch.
