Description

On-Off Switching System for Remote Controling the Automobile Door}

The present invention relates to a car door remote opening and closing device for opening and closing the car door lock remotely.

In more detail, if the present invention is possessed by the present invention, the door lock device of the vehicle is automatically opened and closed. When the present invention possessed by the owner of the car is approached within a certain distance of the car, the door lock is opened, and further away from the car. The ground door lock is locked.

Therefore, you can easily open and close the door lock of the car without pressing the conventional remote control button or using the car key to open the car door lock, and if you have this device, it is safe to check the lock of the door lock. Since it is a micro device, it is easy to carry.

The present invention is made for the purpose of improving the cumbersome method of opening and closing the door lock of the vehicle by using a conventional key or remote control.

In the present invention, while the vehicle door lock is locked, the RF (Radio Freguency) transmitter 1 attached to the vehicle outputs a specific signal at regular intervals. The RF transceiver 2 possessed by the owner of the vehicle is always in the standby mode, and when the vehicle approaches a certain distance, it receives a signal transmitted from the RF transceiver 1.

The RF transceiver 2 receives the signal of the RF transmitter 1 and simultaneously outputs a specific signal, and the RF transmitter 1 receives the signal transmitted from the RF transmitter 2 and drives the relay accordingly to open the door lock. At this time, the RF transceiver 2 does not transmit any more even after receiving a signal transmitted from the RF transmitter 1 even after one transmission and reception.

The next RF transmitter and receiver 2 outputs a specific signal once when it is within a predetermined distance not receiving the signal transmitted from the RF transmitter 1, and the RF transmitter 1 is a system that closes the door lock device by receiving the signal from the RF receiver 2. Configured.

And a code reader 14 which compares the value set by the code setter 7 with the value output from the amplifying unit 13 to determine whether it is output and turns it ON once when it is turned ON and OFF when it is input once again. An amplifying unit 15 for amplifying the signal output from the unit 14 to enable relay driving, a relay 16 for turning on the door lock switch contact point of the signal output from the amplifying unit 15, and a relay 16; Door lock switch 17 for connecting the contact signal output from the signal and the transmission signal and code detected by the demodulator 30 Set the output time by receiving the signal output from the code reader 32 for comparing the value set in the periodicity 31 and measuring the distance and the amplification unit 33 for amplifying the signal output from the code reader 32 It is an automobile door remote switching device comprising a switching circuit 36 for supplying power to the entire transmission circuit section of the RF transmitter and receiver 2 in conjunction with the output delay unit 25 and only when there is an output from the code reader 32.

The oscillator 1 of the RF transceiver 1 attached to the vehicle generates a carrier wave, amplifies it in the amplifying unit 2, and transmits it to the modulator 3. In the modulator 3, an arbitrary set code signal amplified by the amplifier 6 through the code setter 7 and the code generator 5 is loaded on the carrier wave generated by the oscillator 1. The modulated wave thus formed is output to the antenna 19 through the antenna common unit 18 via the amplifier 4 for spatial radiation.

The above operation continues when power is input.

When the RF (Radio Freguency) transmitter 2 possessed by the automobile owner approaches the vehicle within a specific distance (about 3 m), the signal emitted through the antenna 19 is received from the antenna 35 and the signal is weak through the antenna common 34. It is input to the amplifier 26 to amplify. The frequency converter 27 converts the signals from the local oscillator 28 and the amplifier 26 into an intermediate frequency.

The intermediate frequency thus formed is amplified by the amplifier 29, and the demodulator 30 extracts the code set by the code setter 7 of the original RF transceiver 1.

The code extracted from the demodulator 30 is input to the code reader 32 together with the code set by the code setter 31 to check whether the codes match the codes of the two code setters, and the signal output from the RF transceiver 1. Determines whether or not is coming.

In this manner, when the codes match, the code reader 32 outputs the codes to the amplifier 33 only once. If the code reader 32 does not receive a signal from the demodulator 30, it means that the RF transceiver 2 has moved away from the vehicle by a certain distance or more. At this time, the code is output to the amplifier 33 only once again.

The amplifier 33 amplifies the code received from the code reader 32 and transmits the code to the output delay unit 25. The output delay unit 25 shortens the code received by the amplifier 33 at the first transmission, and lengthens it at the time of sending it once. The signal transmitted from the output delay unit 25 is input to the amplifier 23.

The oscillator 20 generates a carrier wave, amplifies the amplifier 21, and sends the carrier wave to the modulator 22. In the modulator 22, the encoded signal amplified by the amplifier 23 is loaded on the carrier generated by the oscillator 20. The modulated wave thus formed is amplified by the amplifier 24 and spatially radiated through the antenna 35 through the antenna common 34.

Since the spatially radiated signal from the RF transceiver 2 is approached within a specific distance from the RF transceiver 1, the signal is transmitted to the amplifier 8 through the antenna common unit 18 through the antenna 19 of the RF transceiver 1.

The encoded signal input to the amplifier 8 is mixed with the local oscillator 10 to form an intermediate frequency through the frequency converter 9 and amplified through the amplifier 11.

The signal amplified by the amplifier 11 extracts the code transmitted from the RF transceiver 2 through the demodulator 12. The signal is input to the code reader 14 together with the code setter 7 through the amplifier 13 and the signal transmitted from the RF transceiver 1 and the signal returned through the RF transceiver 2 are compared and inverted once. The signal is sent to the amplifier 15.

The amplifier 15 amplifies the relay to enable driving, and the relay 16 receives the signal output from the amplifier 15 to turn on / off the relay contact to turn the door open / close switch 17 ON / OFF.

RF transmitter and receiver 2 is portable, so when the output from the code reader 32 to reduce power consumption signal is applied to the switching circuit 36 is a car door remote opening and closing device that is operated by supplying power to the entire transmitting unit of the RF transceiver 2. .

By using this product, you can easily open and close the door lock of the car without pressing the existing remote control button or using the car key to open the car door lock device. It is possible to achieve a safe door lock even without it, and also has an advantage of being very portable because it is very small.
