Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is for a vehicle in which the intermittent cycle is varied depending on the strength of the operating force of the operation switch to control blinking of emergency light groups such as hazard lamps and high mount stop lamps. The present invention relates to an emergency light control device.

[Prior Art] Recently, in order to avoid a rear-end collision accident during braking of a vehicle, an emergency light such as a hazard lamp is blinked during braking to call attention to the following vehicle.

When performing such an operation, for example, when manually operating the tumbler type switch, it is necessary to perform an ON operation for starting the hazard lamp blinking and an OFF operation for ending the blinking.
That is, the switch operation was required twice.

Therefore, conventionally, a technique has been proposed in which a timer circuit is used as shown in Japanese Utility Model Laid-Open No. 1-157041, and the blinking of a hazard lamp is automatically terminated after a predetermined time by this timer circuit.

[Problems to be Solved by the Invention] However, in the above-described conventional technique, it is necessary to provide an automatic return type switch for operating in an emergency in addition to a well-known hazard switch that keeps a hazard lamp in a blinking state. . Further, when blinking an emergency light such as a hazard lamp during braking as described above, for example, it was not possible to raise the degree of alerting to another vehicle in the same blinking cycle as the blinking cycle that normally flashes when the road is stopped. .

[Means for Solving Problems] In this invention, an emergency operation operation and a normal operation operation can be selectively used with a single switch, and an intermittent cycle during the emergency operation operation and the normal operation operation can be changed. It is intended to provide an emergency light control device for a vehicle.

In order to achieve the above object, a vehicle emergency light control device according to the present invention comprises an emergency light group provided in a vehicle, a blinking circuit connected to the emergency light group, and having a cycle changing unit, A first opening / closing part that is electrically connected by the first operation force; and a second
A multi-stage operation switch having a second opening / closing section that conducts by the operation force of the multi-stage operation switch, the first opening / closing section of the multi-stage operation switch, and the blinking circuit, A time circuit for setting a short and short period of a circuit for a predetermined time, a second circuit opening / closing section of the multistage operation switch and the blinking circuit connected, and an interruption of the blinking circuit by closing the second open / close section of the multistage operation switch. A holding circuit for setting a long period is adopted.

[Operation] The present invention equipped with each of the above means operates as follows.

 First, the emergency operation will be described.

For example, when an emergency light group is made to blink to give a notice of deceleration to a following vehicle as the vehicle approaches a tollgate on a highway, the occupant of the vehicle operates the multistage operation switch with a first operation force, for example, relatively weak. Press with force. When the multi-stage operation switch is pressed with a comparatively weak force, the first opening / closing portion is closed to activate the time circuit.

The time limit circuit sets the intermittent period of the blinking circuit to be short for a predetermined time from the time of starting.

As a result, the emergency light group starts high-speed blinking in response to the operation of the multistage operation switch, and automatically ends after a predetermined time.

 Next, the normal operation will be described.

For example, when blinking the emergency light group to temporarily stop at the road shoulder, the occupant of the vehicle operates the multistage operation switch with the second operation force,
For example, the pressing operation is performed with a relatively strong force. When the multistage operation switch is pressed with a comparatively strong force, the second opening / closing portion is closed to activate the holding circuit.

The holding circuit sets the intermittent period of the blinking circuit to be long from this starting point.

As a result, the emergency light group starts the normal low-speed blinking in accordance with the operation operation of the multistage operation switch.

The oscillation frequency of the oscillation section 2f is lowered, and the relays 2h, 2
The intermittent period of i, 2j is set to be long. Further, when the transistor 2e is turned off, the time constant is shortened to increase the oscillation frequency of the oscillator 2f, and the intermittent period of the relays 2h, 2i, 2j is set short.

Next, the multi-stage operation switch 3 is a contact of the first opening / closing section that is brought into conduction by the first operation force, that is, a relatively weak pressing force.

When the contact 3c and the contact 3d of the opening / closing part are bridged by the movable contact piece 3e, it is a circuit that sets the intermittent period of the blinking circuit 2 to be long, and the NAND gates 5a and 5b, the flip-flop 5c, the diodes 5d and 5e, and the transistor 5f. , 5g, capacitors 5h and 5i, and resistors 5j to 5s. The flip-flop 5c is a D-TYPE MASTER SLABE FLIPFLOP TC4013B.
Use IC such as P.

The flash unit 8 includes a turn signal switch 9
Is an existing unit that blinks the hazard lamps 1a, 1b on one side of the hazard lamps 1a-1d, for example, by operating the right side.

 Next, the operation of the embodiment having the above configuration will be described.

(A) The multi-step operation switch 3 is set to the first operation force, that is,
In the case where the pressing operation is performed with a comparatively weak force, the contact 3a and the contact 3b of the multi-step operation switch 3 are connected by the movable contact piece 3e, and the "0" level signal is input to the time circuit 4.

In the time limit circuit 4, the output of the NAND gate 4b is inverted to the "1" level by the input of the "0" level signal, and the resistors 4k and 4l
The capacitor 4f is charged via the. Then, the NAND gate 4a outputs a "0" level signal for a predetermined time until the charging of the capacitor 4f progresses and the level of the connection point A exceeds the threshold level of the NAND gate 4a. The charging time of the capacitor 4f can be adjusted by the variable resistor 4l.

Now, the output of the NAND gate 4a is output to the transistor 2r of the blinking circuit 2 through the resistor 4j, and the output of the NAND gate 4a becomes a "0" level transistor for a predetermined time.
2r turns ON and excites relays 2l and 2j.

When the contacts 2l and 2m are closed by the excitation of the relay 2i, the oscillator 2f of the blinking circuit 2 inputs the "0" level through the resistor 2o, the contacts 2l and 2m and the hazard lamps 1a to 1d to perform the oscillation operation. To start. Then, the oscillating unit 2f outputs an intermittent signal to the relay 2h, periodically opens and closes the contact 2k, and the hazard lamp 1a
~ 1d and high mount stop lamp 1e blink.

The intermittent period of the blinking circuit 2 is determined by the time constant of the period changing unit 21, but at this time the holding circuit 5 is not operating, the transistor 2e of the period changing unit 21 is in the OFF operation state, and the period changing unit is 21 has a short time constant. Therefore, the intermittent period of the blinking circuit 2 is short.

In short, when the multi-step operation switch 3 is pressed with the first operation force, that is, a comparatively weak force, the emergency light group 1 including the hazard lamps 1a to 1d and the high mount stop lamp has a short intermittent cycle for a predetermined time. For example, 100 [cp
Flashes rapidly in the [m] cycle.

(B) The multi-step operation switch 3 is operated with a second operation force, that is,
In case of pressing operation with relatively strong force At this time, in the multistage operation switch 3, the contact point 3c and the contact point 3d are connected by the variable contact piece 3e, and the "0" level signal is input to the holding circuit 5.

The holding circuit 5 sends the “0” level signal to the NAND gate 5
The one-shot signal is waveform-shaped by a and 5b and input to the flip-flop 5c. The flip-flop 5c has an input section
It has a function to alternately invert the output section to "0" level and "1" level each time a "0" level signal is input to CK.
The output section is inverted from the "1" level to the "0" level by the input of the "0" level signal. As a result, the blinking circuit 2
The transistor 2e and the transistor 2r of are activated.

The blinking circuit 2 excites the relays 2i and 2j by the ON operation of the transistor 2r, and starts the oscillation operation of the oscillator 2f.

At this time, the cycle variable unit 21 lengthens the time constant by turning on the transistor 2e, and the blinking circuit 2 opens and closes the contact 2k at a long cycle.

The holding circuit 5 inverts the output part of the flip-flop 5c to the "1" level when the multi-stage operation switch 3 is again operated by the second operation force, that is, strongly pressed, and stops the control of the blinking circuit 2. However, control is also stopped by other input conditions.

For example, when the turn signal switch 9 is operated to the right while the holding circuit 5 is operating, the base potential of the transistor 5f becomes high potential, the transistor 5f is turned off and the transistor 5g is turned on. As a result, the "1" level signal is input to the input portion CL of the flip-flop 5c,
The output section becomes "1" level and the control of the blinking circuit 2 is stopped. Similarly, the time circuit 4 also includes the turn signal switch 9
When the transistor 5f is turned off in accordance with the above operation, one end of the input of the NAND gate 4a is grounded via the diode 5d and the resistor 5o, and the control of the blinking circuit 2 by the time circuit 4 is stopped.

In short, when the multi-stage operation switch 3 is pressed with the second operation force, that is, with a relatively strong force, the emergency light group 1 blinks at a low speed in a cycle of 85 [cpm] with a long intermittent cycle. The emergency light group 1 stops blinking when the multi-stage operation switch 3 is strongly pressed again or the turn signal switch 9 is operated.

In the embodiment described above, the high mount stop lamp 1e is configured to blink by the operation of the holding circuit 5, but the high mount stop lamp 1e is configured to blink only by the operation of the time limit circuit 4. May be. Further, in the embodiment, the structure in which the multi-step operation switch 3 is pressed is exemplified, but various structures such as a tendency operation and a pulling operation of the lever are possible.

[Advantages of the Invention] Since the present invention has the above-described configuration and operation, it is possible to selectively use the emergency operation operation and the normal operation operation with one switch. That is, the multi-stage operation switch is the first
There is an effect that the operating mode of the emergency light group can be changed depending on the operating force of, for example, a weak pressing and a second operating force, for example, a strong pressing.

In addition, the intermittent cycle can be changed between the emergency operation and the normal operation. That is, for example, by shortening the blinking cycle of the emergency blinking that blinks as a notice before deceleration and braking compared to the blinking cycle that normally blinks when the road is stopped, it is possible to improve the degree of alerting to other vehicles. It has an excellent effect that it can be done.
