Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a headlight lighting device for a motorcycle.

[0002]

2. Description of the Related Art Even when a motorcycle is traveling with its headlights lit, the headlights are turned off when the vehicle is stopped, such as when waiting for a signal, and the headlights are lit when traveling again. The operation is troublesome for the rider.

Therefore, there has been proposed a device in which the headlight is automatically turned on when the vehicle is running and turned off when the vehicle is stopped (see Japanese Patent Laid-Open No. 50-39934).

[0004]

By the way, depending on the situation, it may not be necessary to turn off the headlight even when the vehicle is stopped, but the device according to the above proposal cannot handle such a case. That is, the device according to the above-mentioned proposal has a drawback in that the headlight cannot be turned on as it is when the vehicle is stopped because it is uniformly turned on when the vehicle is running and turned off when the vehicle is stopped regardless of the intention of the rider.

The present invention has been made in view of the above problems, and the object thereof is to automatically turn on the headlights while the vehicle is running, but when the vehicle is stopped, the headlights may be dimmed or kept on depending on the situation. It is an object of the present invention to provide a motorcycle headlight lighting device that can be arbitrarily selected by a rider.

[0006]

In order to achieve the above object, the present invention provides a headlight lighting circuit, a stop switch which is turned on when a motorcycle is stopped, a dimming switch to be turned on by a rider, and the stop switch. The headlight lighting device of the motorcycle is configured by incorporating a control circuit for dimming the headlight by turning on the dimming switch in the ON state of the vehicle and turning on the headlight when the stop switch is in the OFF state. Its characteristic.

[0007]

According to the present invention, when the motorcycle is stopped, the stop switch is turned on, and in this state, if the rider turns on the dimming switch, the headlights are dimmed, and if not turned on, The lighting state of the headlight is maintained. Therefore, when the motorcycle is stopped, the rider can arbitrarily select dimming or keeping the headlights lit depending on the situation.

When the stopped motorcycle starts running again, the stop switch is turned off, so the headlights in the dimmed state are automatically turned on, and the headlights kept in the turned-on state remain unchanged. Continue to light up.

In the present invention, dimming of the headlight includes extinction.

[0010]

An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is an electric circuit diagram of a headlight lighting device according to the present invention, and FIG. 2 is a flow chart for explaining the operation of the device.

In the headlight lighting circuit shown in FIG. 1, 1 is a battery and 2 is ON when the motorcycle is stopped.
Then, a stop switch that is turned off when the vehicle is running, 3 is an indicator lamp that is turned on when the motorcycle is stopped, 4 is a dimming switch that the rider should manually turn on, 5 is a control circuit, 6 is a headlight, 7 is a headlight 6 The light of Lo
It is a changeover switch for changing over to a beam and a Hi beam.

By the way, the stop switch 2 is turned on / off by a signal from a detection device (not shown) for detecting a meshing gear of a transmission (not shown). If the gear is in the neutral state, it is turned on, otherwise (that is, when the transmission gear is in the in-state and the motorcycle is in the running state).
Is turned off. In addition to the above, for example, a speed sensor or the like can be used as the means for detecting the stopped state of the motorcycle.

The control circuit 5 includes a holding circuit 8 and a dimming circuit 9. The holding circuit 8 is a relay circuit, which is composed of a diode 10, an exciting coil 11 and a switch 12. Has been done. Also, the dimming circuit 9
Is composed of a relay circuit 15 composed of an exciting coil 13 and a switch 14, and a resistor 16. A semiconductor may be used instead of the resistor 16.

Next, the operation of the headlight lighting device according to this embodiment will be described with reference to the flow chart shown in FIG.

When the motorcycle is in a traveling state, the stop switch 2 remains OFF as described above (FIG. 2).
Therefore, the exciting coil 11 of the holding circuit 8 is not energized, and the switch 12 of the holding circuit 8 also maintains the OFF state (STEP 3 in FIG. 2). In this state, the exciting coil 13 of the dimming circuit 9 is not energized, so the switch 14 of the dimming circuit 9 is turned on (STEP 4 in FIG. 2), and the current from the battery 1 is switched to the Lo side. 7 and the switch 14 of the dimming circuit 9 flow to the headlight 6 and the headlight 6 is turned on (STEP in FIG. 2).
5).

When the motorcycle is stopped due to waiting for a signal or the like, the stop switch 2 is turned on (steps 1 and 6 in FIG. 2) and the display lamp 3 is turned on as described above.
At this time, when the rider turns on the dimming switch 4, the exciting coil 11 of the holding circuit 8 is energized to turn on the switch 12 (STEPs 7 and 8 in FIG. 2), so that the current from the battery 1 is applied to the switch 12. Through the exciting coil 13 of the dimming circuit 9, and the switch 14 is turned off.
F (STEP 9 in FIG. 2). Then, the current from the battery 1 flows to the headlight 6 through the changeover switch 7 and the resistor 16 of the dimming circuit 9, but the current value at this time is suppressed to a small value by the resistor 16, so the headlight 6 is dimmed. (STEP 10 in FIG. 2). Even if the rider releases the dimming switch 4 after turning on the dimming switch 4 as described above, the O of the switch 12 of the holding circuit 8 is changed.
The N state is maintained as it is.

On the other hand, if the rider does not turn on the stop switch 4 when the motorcycle is stopped, the holding circuit 8 and the dimming circuit 9 are not energized as in the case of running, and the switch 1
2 is OFF and switch 14 is ON (ST of FIG. 2
Because of EP7, 3, 4), the headlight 6 maintains the lighting state as it is (STEP 5 in FIG. 2).

Therefore, according to this embodiment, when the motorcycle is stopped, the rider can arbitrarily select dimming or keeping the headlight 6 lit depending on the situation.

Next, for example, when the signal changes from red to blue and the motorcycle starts, the stop switch 4 is turned off as described above (STEPs 1 and 2 in FIG. 2), so the holding circuit 8 and the dimming circuit 9 are connected. Is not energized, the switch 12 is turned off, and the switch 14 is turned on (STEP 7, 3, in FIG. 2).
4) Therefore, the headlight 6 in the dimmed state is automatically turned on, and the headlight 6 kept in the turned-on state continues to be turned-on (STEP 5 in FIG. 2).

In the present invention, dimming of the headlight includes extinction. In this embodiment, if the resistance value of the resistor 16 of the dimming circuit 9 is set large, the headlight 6 is practically extinguished. can do.

By the way, although the dedicated dimmer switch is newly provided in the above embodiments, it is difficult in terms of space to add a new dimmer switch around the handle of the motorcycle provided with various switches. Therefore, the operation becomes complicated.

Therefore, it is conceivable that the existing switch also functions as a dimming switch. That is, the passing switch, which is an existing switch, is used for an overtaking signal, and this is unnecessary when the motorcycle is stopped. On the other hand, the dimming switch is used only when the vehicle is stopped and is not necessary during traveling. Therefore, if the existing passing switch is also used as the dimming switch, it is not necessary to newly add a dedicated dimming switch, which is convenient. Here, a specific example thereof will be described with reference to the electric circuit diagram shown in FIG. In FIG. 3, the same elements as those shown in FIG. 1 are designated by the same reference numerals, and description thereof will be omitted below.

In FIG. 3, 17 is an existing passing switch, which also functions as a dimming switch as described later.

Thus, in this embodiment, the control circuit 5
Includes relay circuits 18 and 19, and one relay circuit 18 is a circuit for switching the passing switch 17 according to its use (use as an original passing switch and use as a dimming switch). This is composed of an exciting coil 20 and a switch 21.
The other relay circuit 19 is a dimming circuit, which includes a diode 22, an exciting coil 23, and a switch 24.

Next, the operation of the headlight lighting device having the above circuit configuration will be described.

When the motorcycle is in the running state, the vehicle stop switch 2 is in the OFF state, so the relay circuit 18
The exciting coil 20 is not energized, and the b contact of the switch 21 of the relay circuit 18 is turned on. Since the exciting coil 23 of the relay circuit 19 is not energized in this state, the b contact of the switch 24 of the relay circuit 19 is also turned on.
Therefore, the current from the battery 1 flows through the changeover switch 7 switched to the Lo side and the switch 24 of the relay circuit 19 to the Lo side of the headlight 6 and the headlight 6 is lit by the Lo beam.

When the rider turns on the passing switch 17 in the above state, the current from the battery 1 flows to the Hi side of the headlight 6 via the passing switch 17 and the switch 21 of the relay circuit 18, so that the headlight is turned on. In No. 6, the Lo and Hi beams are turned on, and the normal passing light operation is performed. Therefore, at this time, the passing switch 17 is used for its original purpose as usual.

When the motorcycle is stopped due to waiting for a signal or the like, the stop switch 2 is turned on and the display lamp 3 is turned on.
Lights up and the exciting coil 20 of the relay circuit 18
Is energized to excite this, the switch 21 a
The contact is turned on. At this time, the passing switch 17
When the rider turns on the switch, the current from the battery 1 flows through the passing switch 17 and the switch 21 to the exciting coil 23 of the relay circuit 19, so that the switch 2
The contact a of 4 is turned on. Then, the relay circuit 19 is held by itself, and even if the passing switch 17 is turned off,
ON state of contact a of switch 24 of relay circuit 19, b
The OFF state of the contact is maintained as it is, and the headlight 6
Since the short circuit of the resistor 16 connected in series with is released,
The current from the battery 1 is the changeover switch 7 and the resistor 16
After that, it flows to the headlight 6. The current value at this time is kept small by the resistor 16, so that the headlight 6 is dimmed. Therefore, in this case, the passing switch 17 functions as a dimming switch similar to that in the above embodiment.

On the other hand, if the rider does not turn on the passing switch 17 when the motorcycle is stopped, the contact point b of the switch 24 of the relay circuit 19 remains in the ON state as in the case of running, and the headlight 6 is connected in series. Since the resistor 16 connected to is short-circuited, the headlight 6 continues to remain lit.

Therefore, also in this embodiment, when the motorcycle is stopped, the rider can arbitrarily select dimming or keeping the headlight 6 lit depending on the situation.

Next, for example, when the signal changes from red to blue and the motorcycle starts, the stop switch 2 is turned off, so that the exciting coils 20 and 23 of the relay circuits 18 and 19 are not energized, and the switch 21 is turned off. , 24 b contacts are O
Therefore, the headlight 6 that has been turned off is automatically turned on, and the headlight 6 that is kept on is automatically turned on.
Continues to light up.

As described above, in the present embodiment, the existing passing switch 17 is also used as the dimming switch, so that it is not necessary to newly add a dedicated dimming switch.
This is advantageous in layout and operation of switches.
