Description

[Detailed Description of the Invention] This invention relates to an automatic control device for automobile lights, and more specifically, it has an automatic control circuit consisting of a relay, a capacitor with a large capacity, and three on/off switches. , is characterized by the automatic turning on and off of the car's lights, which eliminates unnecessary switch operations and saves unnecessary current when parking, parking or driving at night.At the same time, the above control circuit prevents theft while the car is parked. It is also used as a warning device for prevention.

With the rapid development of commerce and industry, automobiles became an indispensable substitute for walking. Moreover, for those who use automobiles in general, it is not only the convenience and speed that automobiles provide, but also the desirable comfort, energy savings,
Automobiles are required to be easy to repair and to be extremely safe to prevent theft. When driving at night, I often see people turning off their headlights while waiting for the light to turn green at an intersection so as not to use up their car's electricity, but the switch is repeatedly operated on one side. Some drivers don't like the inconvenience caused by this and leave their headlights on. In addition, if the person using the vehicle leaves the vehicle for a period of time by parking it or stopping on the side of the road, a skilled thief will drive the vehicle away and modify it within a short period of time. or disassemble it and use it for crimes.

As a result, people who use cars suffer great damage, and it has become a serious social problem, and the reality is that it occurs more frequently and cannot be prevented.

The present invention provides an anti-theft alarm system that uses an easily installed control circuit to automatically turn on and off vehicle lights to save power without compromising maintenance costs. The present invention aims to provide an automatic control device for the lights of a car, thereby eliminating the troublesome operation of switching the lights of a car when at an intersection or when starting or stopping. Yet another object of the present invention is to enable a thief to activate the above-mentioned control circuit in a parked car so that as soon as the thief drives the car, a loud horn or car lights that will definitely attract the attention of neighbors. An object of the present invention is to provide an anti-theft alarm device which is characterized by lighting up the alarm, thereby achieving anti-theft prevention of automobiles.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in Figure 1, the control circuit described above uses a car's storage battery as a power source, and has one switch connected to the open/close switch, which is a conventional light switch in a general car, and one relay R - parallel to the coil of the relay. 2 is used for the capacitor 〇 connected to , and the open/close switch for manual and automatic switching connected in series to the power supply BT.

Additionally, there is a neutral open/close switch number 3, which is controlled by the gear change rod. That is, the open/close switch 3 is controlled to close when the rod is in high gear or low gear, and to open when the rod is in neutral.

The alarm switch 4 is connected in series between the horn BZ and the horn push button 6 attached to the steering wheel so as to constitute a horn transmission ring circuit. 6. It consists of a power supply BT, and when K4 is switched, the above-mentioned control circuit and horn BZ constitute a circuit of an alarm device for preventing theft. Further, 5 is a changeover switch for controlling the operating light and the dimming device.

The features of the operation of the control circuit described above can best be seen in the following description of the drawings. When driving at night, use the car lights that illuminate when the power supply BT and circuit are closed)
1 to the car light switch to close the circuit described above.

However, if the opening/closing switch is set to the manual position (2), the circular circuit of the car light operates as a conventional car light, so the driver only has to control the switch (5) to select between the driving light and the dimmer.

When 2 is in the automatic position on the open/close switch, the anode of the power supply BT is induced into the coil of the relay via 1, K2, and K3, returns to the cathode of the power supply BT, forming a circular circuit, and the relay is activated. The normal contact switch switches from contact 1 and 2 to closed contact 2 and 3, and in this circular circuit the power supply BT is guided from 1 and relay contacts 2 and 3 to the headlight) L, and the power supply BT Return to the circular circuit?
This is what lights up your car's lights.

Furthermore, K3 is an opening/closing switch that is controlled by the operation of the gear, and when the gear change rod is in the low speed gear for starting, acceleration gear, or high speed gear, the above-mentioned car light 1. lights up. Also, when you come to an intersection and stop there waiting for a green light, the gear change rod is returned to neutral and the K3
is released, the automatic control circuit described above is opened, the coil of the relay is not excited, the circuit between relay switches 2 and 3 becomes an open circuit, and the car lights are automatically turned off.

When the car starts again, the gear change rod is immediately put into the predetermined gear position, so that 3 is closed and activates the relay, and the control circuit becomes a circular circuit again to turn on the car's lights.

If you change gears while driving, the gear change rod will normally disengage from the neutral position and the car's lights will flash. The capacitors 〇 at both ends of the relay coil make it possible to eliminate these inconveniences. As shown in Figure 1, capacitor C is connected in parallel with the relay coil, and when K3 is released by the gear change rod, capacitor C energizes the above coil until it is completely discharged and contacts 2.
and 3 can be kept closed. Therefore, when the gear change rod passes through the neutral position, the control loop described above will not affect the illumination of the vehicle's lights, even if 3 is open.

The discharge time is determined by the size of the coil and the capacitance of the capacitor. The capacitance of the capacitor should be 1000 F or 2000 F to achieve the normal discharge time of 3 to 3 seconds.
F is sufficient.

When the driver leaves the car for a while or tries to park it, he can use the switch 4 to release the horn pushbutton above the steering wheel, and the automatic control circuit described above can be prevented from being stolen. Control horn for prevention alarm.

As shown in Fig. 1, the ring circuit includes the horn BZ and the open/close switch 4, but the control circuit described above is connected in parallel with the car lights, and its operating characteristics are as described previously. Similarly, if a thief gets into the car and operates the gear change rod, the above circuit will be closed at 3, and the horn will be turned off at B.
Close the power supply BT between Z and the car's lie (L). Therefore, just before the car starts, the horn will sound loudly and the lights will come on to attract the attention of the neighbors, and this will continue until 4 is released or the gear change rod is placed in the neutral position.

Even if the thief immediately puts the rod in the neutral position, the car will not go far because the gear will not be engaged, and the thief will be caught immediately due to this troublesome problem that goes against the thief's wishes.

If you attach three open/close switches, a relay, and a capacitor to a conventional car light circuit,
The purpose of automatically turning on/off car lights and anti-theft alarm can be achieved. Therefore, this invention with sensitive operation, simple structure and dual functions is a novel and useful creation.
