BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a vehicle flasher device to which the present invention is applied will be described in detail with reference to FIGS.

First, the structure will be described. FIG. 1 is a circuit diagram of an electric circuit 100 included in the vehicle flasher device according to the present embodiment. As shown in FIG. 1, an electric circuit 1
00 is a logic circuit 101, a transmission / reception antenna 102, a transmission / reception control switch 103, an input amplifier 104,
It is composed of a detector 105, a transmission amplifier 106, a modulator 107, a multivibrator 108, a timing selection control switch 109, a signal indicating switch 110, a relay driver 111, a blinking relay 112, and a flasher lamp 113.

The logic circuit 101 is an operation unit (not shown) having a turn signal switch, a hazard switch and the like.
The instruction to start the signal is recognized via the
It is determined whether or not the detection signal is output from 05.
Further, the logic circuit 101 controls the transmission / reception control switch 103 and the timing selection control switch 109 based on these results.

The transmission / reception antenna 102 transmits / receives radio waves to / from the transmission / reception antenna 102 provided in another vehicle, and is either an input amplifier 104 or a transmission amplifier 106 via a transmission / reception control switch 103. Connected to the crab.

The transmission / reception control switch 103 is
Under the control of the logic circuit 101, the transmission / reception antenna 102 and the input amplifier 104 or the transmission / reception antenna 102 and the transmission amplifier 106 are connected. In the initial state, the transmitting / receiving antenna 102 and the input amplifier 104 are connected.

The input amplifier 104 is a transmission / reception antenna 10.
The radio wave received by 2 is amplified and output to the detector 105.

The detector 105 demodulates the radio wave output from the input amplifier 104, detects the signal level of the modulated wave of the radio wave, converts the signal level into a voltage, and selects the multivibrator 108 as a detection signal and timing selection. Output to the control switch 109. Also, the detector 10
5 outputs to the logic circuit 101 whether or not the detection signal is output.

The sending amplifier 106 amplifies the radio wave output from the modulator 107 and sends it to the outside via the transmitting / receiving antenna 102.

The modulator 107 includes a signal indicating switch 11
A signal output from 0 to the relay driver 111, that is,
Phase modulation is performed using a signal (timing signal) indicating the timing at which the flasher lamp 113 blinks as a modulating wave, and the carrier wave is output to the sending amplifier 106.

The multivibrator 108 is a self-propelled oscillator circuit which is composed of capacitors, resistors, transistors, etc. and operates automatically, and outputs a pulse voltage to the timing selection control switch 109 at predetermined intervals.

Timing selection control switch 1
Control 09 of the logic circuit 101 connects the detector 105 to the signal indicating switch 110 or the multivibrator 108 to the signal indicating switch 110.
In the initial state, the multivibrator 108
And the cue instruction signal switch 110 are connected.

The signal indicating switch 110 connects / disconnects (ON / OFF) the timing selection control switch 109 and the relay driver 111 under the control of the logic circuit 101 according to the presence or absence of a signal indicating a signal.

The relay driver 111 uses the signal output from the signal indicating switch 110 as a drive source to drive and control the blinking relay 112. That is, the blinking relay 112 is
The contacts are opened and closed in synchronization with the oscillation timing of the multivibrator 108 or the detection signal output from the detector 105. The flasher lamp 113 blinks according to the opening / closing timing of the blinking relay 112.

FIG. 2 is a diagram showing an example of the circuit configuration of the logic circuit 101 described above. In FIG. 2, the logic circuit 101
Includes a NOT circuit 101a and an AND circuit 101b.

When the detection signal is output from the detector 105, the logic circuit 101 switches the timing selection control switch 109 from the multivibrator 108 side to the detector 105 side.

Further, when the start of the signal is instructed, the logic circuit 101 turns on the signal 110 for instructing the signal, and turns on the switch 103 for transmission / reception control only when there is no detection signal output from the detector 105. The input amplifier 104 side is switched to the sending amplifier 106 side.

Next, the operation will be described. First, when a driver gives an instruction to start a signal, the logic circuit 101
The signal indicating signal switch 110 is turned on and the transmission / reception controller switch 103 is controlled so that the timing selection control switch 109 and the relay driver 111 are connected to each other, and the connection destination of the transmission / reception antenna 102 is changed to the input amplifier. Sending amplifier 10 from 104
Switch to 6.

The flasher lamp 113 blinks at the timing of oscillation of the multivibrator 108, and the radio wave phase-modulated by the modulator 107 at the same timing is sent to the outside via the sending amplifier 106 and the transmitting / receiving antenna 102. It

When the end of the signal is instructed, the logic circuit 10
1 turns off the signal indicating switch 110 and controls the transmission / reception control switch 103,
The connection destination of the transmitting / receiving antenna 102 is returned to the input amplifier 104.

By the way, when the transmission / reception antenna 102 receives a radio wave transmitted by the transmission / reception antenna 102 mounted in another vehicle, the detector 105 detects the radio wave and outputs the detection signal to the timing selection control switch 109. At the same time as outputting, it outputs to the logic circuit 101 that the detection signal is output. Then, the logic circuit 101 controls the timing selection control switch 109 to switch the connection destination of the signal indicating switch 110 from the multivibrator 108 to the detector 105.

In this state, when the start of the signal is instructed,
The connection destination of the transmission / reception antenna 102 remains the input amplifier 104, and the signal 110 for signal indication is turned on. That is, based on the detection signal output from the detector 105,
The flasher lamp 113 starts blinking.

The multivibrator 108 continues to output a pulse voltage of a certain length in synchronization with the detection signal by continuously resetting its oscillation by the detection signal input from the detector 105 (see FIG. 3). That is, even if the reception or demodulation of radio waves is interrupted and the input of the detection signal from the detector 105 is interrupted, the multivibrator 108 continues to oscillate and the timing selection control switch 109 causes the multivibrator 108 to continue.
By switching to the side, flashing of the flasher lamp 113 is not interrupted while the signal is instructed.

The delay circuit 11 is provided between the detector 105 and the timing selection control switch 109.
By providing 4, the detection signal received from another vehicle flasher device can be subjected to a delay process and the blinking timing can be shifted (see FIG. 4).

FIG. 4 is a diagram showing an example of a blinking operation of such a vehicle flasher device. As shown in FIG. 4, with car A as a reference, car B has a 1/8 cycle, and car C has a 1/8 cycle.
By performing delay processing of 4 cycles and 3/8 cycle for the D car, it is possible to blink the vehicle flasher device so that the A car, the B car, the C car, and the D car flow. That is, it is possible to blink the vehicle that is the transmission source of the detection signal at the same cycle with a constant delay. The delay value is arbitrary.

As described above, according to the vehicle flasher device of the present embodiment, by transmitting and receiving the radio wave including the signal capable of specifying the blinking timing, the other flashing timing is started earlier. It can be synchronized with the vehicle flasher device. Therefore, when a plurality of vehicles are traveling at the same time, such as when demonstrating, it is possible to give the viewer a sense of unity.

Further, by sequentially changing the delay value and performing the delay process, it is possible to make the continuous vehicle flasher device blink in a flowing manner to further improve the appearance.

The description content in the present embodiment is a suitable example, and the present invention is not limited to this. The detailed configuration and detailed operation of the present embodiment can be appropriately modified without departing from the spirit of the present invention.

[0035]

According to the present invention, since the blinking timing is shared through radio waves, the blinking timing can be synchronized between the devices and a unified feeling can be created.
