Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hazard circuit, and more particularly to a hazard circuit for flashing a left turn signal or a right turn signal when a right turn signal or a left turn signal is operating during backing. Is.

[0002]

2. Description of the Related Art FIG. 3 shows a conventional hazard circuit (1).
In the figure, 1 is a right / left turn switch, 2 is a left turn indicator that blinks when the right / left turn switch 1 is selected in the left turn direction, and 3 is also the right / left turn switch 1 is selected in the right turn direction. A right-side turn signal, which flashes occasionally, 4 is a flasher unit for turning the turn signals 2 and 3;
Is a left-turn buzzer that operates only when the left turn signal 2 blinks, 6 is a key switch, 7 is a battery for supplying power to the flasher unit 4 via the key switch 6, 8
Has a contact point connected in parallel with the key switch 6, and by operating the switch from the flasher unit 4 to the direction indicator 2,
A hazard switch for blinking 3 at the same time, 9 is a back lamp, and 10 is a back lamp switch as a back operation switch that operates when a gear (not shown) is put in the back and turns on the back lamp 9.

In the operation of the conventional example (1), when the key switch 6 is turned on, the power from the battery 7 is applied to the flasher unit 4.

In such a state, when the driver operates the right / left turn switch 1 to the left turn side, for example, the flasher unit 4 forms a series electric circuit by the right / left turn switch 1 and the left turn signal 2 and is a voltage for blinking. Is given to the left direction indicator 2, so that the left direction indicator 2 blinks by the output voltage (blinking voltage) of the flasher unit 4.

At this time, since the series circuit of the left buzzer 5 and the right direction indicator 3 is connected in parallel with the left direction indicator 2, the left turn buzzer 5 operates and a buzzer sound is generated. Since the left-turn buzzer 5 has a large resistance value, a small amount of current flows, so that the right turn indicator 3 does not blink.

When the right / left turn switch 1 is operated in the right turn direction, the right turn indicator 3 also blinks due to the blinking output voltage of the flasher unit 4 in the same manner. However, in this case, since the left-turn buzzer 5 has a rectifying function, no current flows through the buzzer 5 itself, so that no buzzer sound is generated during a right turn.

Further, if the hazard switch 8 is operated,
Since the flasher unit 4 is connected to both the turn indicators 2 and 3, the turn indicators 2 and 3 simultaneously blink according to the output voltage thereof.

When the back gear is operated, the back lamp switch 10 is turned on, so that the back lamp 9 is turned on.

FIG. 4 shows a conventional hazard circuit (No. 2), which has a simpler structure than the conventional example (No. 1) shown in FIG. 3. The flasher unit 4 has a left turn switch 1A and a left turn switch 1A. The right turn switch 1B, the left turn direction indicator 2 and the right turn direction indicator 3 are connected to the ground potential as shown in the figure, and the left turn buzzer 5 is connected between the direction indicators 2 and 3. The hazard switch 8 is connected to the flasher unit 4 in parallel with the left turn switch 1A and the right turn switch 1B.

In the operation of the conventional example (part 2), for example, when the left turn switch 1A is operated, a serial electric circuit is formed in the flasher unit 4 and a blinking voltage is applied to the left turn indicator 2 by the internal circuit. Since it is given, only the left turn indicator 2 blinks.

At the same time, a current flows through the left turn buzzer 5 and the right turn direction indicator 3, and the left turn buzzer 5 as in the case of FIG.
A buzzer sound is generated from. However, since the current is small, the right direction indicator 3 does not blink.

Further, when the right turn switch 1B is operated, the flasher unit 4 gives a blinking voltage only to the right direction indicator 3, so that only the right direction indicator 3 blinks. In this case, the left turn buzzer 5 does not operate.

Further, when the hazard switch 8 is operated, the left turn switch 1A and the right turn switch 1B are operated at the same time. Therefore, the flasher unit 4 simultaneously gives a blinking voltage to the direction indicators 2 and 3, and therefore these direction indicators 2 And 3 simultaneously perform the blinking operation.

[0014]

In the conventional example as described above, as shown in FIG. 5, the back gear enters while the steering wheel is turned to the left and the left turn signal indicator 2 is still operating. If the vehicle moves backward, the vehicle will behave as shown.

At this time, the left turn buzzer 5 is activated to output an alarm to the left side of the vehicle.

However, since the vehicle moves as shown in FIG. 5, there is no danger of causing a danger to the motorcycle or a person on the left side, but rather to a motorcycle or a person on the right side of the vehicle. There was a problem that it is likely to occur.

Further, there is a problem that a right-handed motorcycle, a person or the like is caught in an accident because he / she is relieved by hearing a sound or a voice "turning left" by a buzzer turning left or voice.

[0018] The invention thus left direction indicator or right turn indicator flasher units corresponding respectively when left switch or right turn switch is operated flashing dynamic
In hazard circuit Ru is created, and an object thereof is to make also possible to generate a safe direction indication and an alarm during back operation.

[0019]

In order to achieve the above object, a hazard circuit according to the present invention is provided with a back operation switch that operates when a back gear is operated, and operates the back gear even if the left turn switch or the right turn switch is operated. <br/> said back operation switch is provided with a control circuit for blinking <br/> both the direction indicator by the output signal of the flasher unit if operated by.

[0020] In the present invention, including an alarm generating means driven by saw the flasher unit when the left turn switch is operated, the control circuit, the left turn switch
With the back operation switch is operated, even if that has been manipulated
In this case, the alarm generating means may not be driven.

[0021]

In the present invention, when the driver puts the gear in the back, the back operation switch is actuated and the back lamp lights up. However, when the driver operates the left turn switch or the right turn switch in this state, the flasher A blinking signal from the unit is given to both turn indicators to cause blinking operation , which is the same as if the hazard switch was operated.

[0022] Thus, the right side of the direction indicator, even if, as the handle has operated the left turn switch off to the left as shown in FIG. 5 also will be blinking at the same time, correct alarm to the bike and people that are present on the right side Can be given.

Further, when the left turn switch is operated, a left turn alarm is issued, but when the back gear is operated as described above, the state is the same as when the hazard switch is operated. since such a case, the control circuit so as not <br/> to generate an alarm from the alarm generating means, and without the unnecessary alarm may misleading.

[0024]

FIG. 1 shows an embodiment (1) of a hazard circuit according to the present invention. This embodiment is an improvement of the conventional example (1) shown in FIG. Relays 11 and 12 and a diode 13 that form a control circuit for
And are provided.

That is, the terminal of the relay 11 is the left turn buzzer 5
Is connected to the connection point between the right turn indicator 3 and the terminal, and the terminal is connected to the connection point between the left turn buzzer 5 and the left turn indicator 2,
The terminal is connected to the connection point between the flasher unit 4 and the right / left turn switch 1, and the terminal is further connected to the back lamp switch 10 via the diode 13.

The terminals of the relay 12 are connected to the terminals of the relay 11, the terminals are connected to the terminals of the relay 11, the terminals are connected to the terminals of the relay 11, and the terminals are connected to the terminals of the relay 11. .

In the operation of such an embodiment, the contact 11 of the relay 11 is operated in the state where the back gear is not operated.
a and the contact 12a of the relay 12 are in the state as shown in the figure, and therefore, they are the same as the right turn operation, the left turn operation, and the hazard operation in FIG.

On the other hand, when the driver puts the gear in the back, the back lamp switch 10 as the back operation switch is turned on and the back lamp 9 is turned on. In this state, for example, the right / left turn switch 1 is operated to the left turn side. In this case, the flasher unit 4 is connected in series with the left direction indicator 2 via the right / left turn switch 1 to form an electric circuit, and therefore, the left direction indicator 2 blinks in the same manner as above.

However, since the output voltage of the flasher unit 4 is applied to the contact on the left turn side of the right / left turn switch 1 at this time, the output voltage of the flasher unit 4 is applied to the terminal of the relay 11 and the relay 11 Since the terminal of the relay 11 is grounded via the diode 13 and the back lamp switch 10, the coil 11b of the relay 11
Is excited and drives the contact 11a to connect the terminal.

Therefore, the right direction indicator 3 has a relay 1
Out of flasher unit 4 via the first terminal (1) and (3)
Becomes possible force voltage is found given, so that the output voltage of the left turn signal 2 in the same manner as in the right direction indicator 3 also flasher unit 4 is blinking given.

At this time, since the same voltage is applied to the left turn signal indicator 2 and the right turn signal indicator 3, the left turn buzzer 5 is not actuated and does not operate.

The above operation is the same when the right / left turn switch 1 is operated to the right turn side. In this case, since the output voltage of the flasher unit 4 is applied to the terminal of the relay 12, the coil 12b of the relay 12 is connected to the terminal. Since the contact 12a is closed by being excited through the diode 13, the back lamp switch 10 and the terminal, the output voltage of the flasher unit 4 is transmitted to the left direction indicator 2 through the terminal, the contact 12a and the terminal. Will also be given, and the left turn indicator 2 will blink at the same time as the right turn indicator 3.

As described above, when the left turn operation or the right turn operation is performed with the back gear set, the same operation as when the hazard switch 8 is operated is exhibited,
In addition, the left turn buzzer 5 does not operate even when the left turn operation is performed.

FIG. 2 shows an embodiment (No. 2) of the hazard circuit according to the present invention. This embodiment is an improvement of the conventional example (No. 2) shown in FIG. The relays 11 and 12 forming the circuit are newly provided.

That is, the terminal of the relay 11 is connected to the connection point between the flasher unit 4 and the right switch 1B, the terminal is grounded, and the terminal is connected to the connection point between the flasher unit 4 and the left turn switch 1A. Connected,
The terminal is connected to the connection point between the back lamp switch 10 and the back lamp 9.

The terminal of the relay 12 is connected to the terminal of the relay 11, the terminal is connected to the terminal, the terminal is grounded, and the terminal is connected to the terminal.

In the operation of such an embodiment, when the driver puts the gear in the back, the back lamp switch 10 as the back operation switch is turned on to turn on the back lamp 9, but in this state, for example, turn left. When the driver operates the switch 1A, the flasher unit 4 causes the left direction indicator 2 to blink.

At the same time, the terminal of the relay 11 is grounded by the left turn switch 1A, and since the terminal is connected to the power source through the back lamp switch 10, the coil 11b of the relay 11 is excited and its contact 11a. Will be closed.

Therefore, although the right turn switch 1B is not operated, both ends of the right turn switch 1B are short-circuited by the contacts 11a of the relay 11, so that the flasher unit 4 causes the right direction indicator 3 to blink at the same time.

Therefore, the voltage across the left turn buzzer 5 is "0".
Therefore, it will not work.

On the other hand, when the right turn switch 1B is operated, the coil 12b of the relay 12 is similarly operated this time.
When the left turn switch 1A is not operated, the both ends thereof are short-circuited and the flasher unit 4 determines that the left turn switch has been operated. The direction indicator 2 will be blinked at the same time.

In the above embodiment, when the steering wheel returns straight, the left turn switch or the right turn switch is automatically turned off, and the hazard state is automatically released. In this case, the vehicle moves to the left or right. There is no need to output an alarm.

When the right turn switch or the left turn switch is turned on while the steering wheel is in the straight direction and the steering wheel is put in the back gear and the steering wheel is simply turned back without turning the steering wheel and the back gear is pulled out, while the back gear is being turned on, Is a hazard condition, but when it is returned to neutral, the right or left direction indicator blinks.

In this case, it may be possible to park the vehicle on the shoulder of the road and move the vehicle slightly backward. However, by making the hazard blink when the vehicle moves backward, the warning effect on the surroundings can be enhanced.

[0045]

As described above, according to the hazard circuit of the present invention, even if the left turn switch or the right turn switch is operated, if the back operation switch is operated, the left turn signal is output by the output signal of the flasher unit. and since it is configured right turn indicator to blink operation simultaneously,
It is possible to realize a semi-automatic hazard circuit that can give an alarm to the motorcycles and people on both sides even if the steering wheel is turned and the steering wheel is turned back while operating left or right.

Further, even when the back operation switch and the left turn switch are operated, it is possible to prevent the alarm generating means from being driven in the same manner as when the hazard switch is operated. It is possible to prevent an accident from occurring by avoiding misunderstanding due to an alarm such as "turning to the right."
