Description

[Detailed Description of the Invention] Technical Field The present invention relates to an instrument panel illumination device for a vehicle such as a motorcycle.

Background technology The instrument panel of a motorcycle includes a speedometer, tachometer,
In addition to instruments that display vehicle operating conditions such as a fuel gauge, accessory instruments such as a clock, trip meter, and radio frequency indicator are also arranged. A lighting device consisting of a lamp or the like is provided so that these instruments can be seen even in a dark environment.

Conventionally, each lamp in a lighting system is supplied with current from the battery through the key switch and then the lighting switch.The key switch is turned on while the vehicle is running, so operating the lighting switch lights up the instrument lighting lamps. It's becoming like that.

However, after stopping the engine when the surroundings are dark, such as at night, you may want to check accessory instruments such as a clock or trip meter, especially the clock.In such cases, first turn on the key switch and then The drawback was that it was time-consuming because it required operating the lighting switch. In addition, at this time, not only all the instrument panel illumination lamps are turned on, but also the vehicle's ignition system is activated, and the head lamps, tail lights, etc. are also turned on, consuming a large amount of battery power.

SUMMARY OF THE INVENTION Therefore, the purpose of the present invention is to provide a vehicle instrument panel illumination device that can illuminate a clock among accessory instruments with a simple operation when the engine is stopped, and prevents wasted battery consumption. It is.

The instrument panel lighting device of the present invention has an accessory contact and an on contact as fixed contacts, and when power output is supplied to the movable contact and the selection position of the operator is at the accessory position, the movable contact contacts the accessory contact. A vehicle instrument panel illumination device comprising a combination switch in which a movable contact contacts an accessory contact and an on contact when the selected position is in the on position, and a clock on the instrument panel that operates regardless of the selected position of the operator. A first lighting element for instrument lighting related to vehicle operation is connected to the ON contact via a lighting switch, and a second lighting element for illuminating a clock is connected to the accessory contact without going through the lighting switch. It is characterized by being connected.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an instrument panel of a motorcycle to which the lighting device of the present invention is applied. In this figure, a speedometer 2 is provided on the right side of the center of an instrument panel 1, and a tachometer 3 is provided on the left side of the center. A trip meter 4 is provided below within the speedometer 2. A clock 5 is provided on the right side of the speedometer 2, and a reception band and its frequency indicator 6 for the in-vehicle radio are provided below it.A fuel gauge 7 is provided on the left side of the tachometer 3, and a temperature gauge 8 is provided below it. are provided for each. Illumination lamps 11 to 15 for illuminating these instruments 2 to 8 are arranged on the instrument panel 1. That is,
The lamp 11 illuminates the clock 5 and the radio display 6, and the lamp 12 illuminates the trip meter 4. Further, the lamp 13 is for illuminating the speedometer 2, the lamp 14 is for illuminating the tachometer 3, and the lamp 15 is for illuminating the fuel gauge 7 and the temperature gauge 8.

In the lighting device according to the present invention equipped with such lighting lamps 11 to 15, as shown in FIG.
3 to the movable contact 24a of the key switch 24. The key switch 24 has three fixed contacts 24b to 24d, the first fixed contact being open and corresponding to the OFF position, and the second fixed contact being open.
It corresponds to the ACC (accessory) position, and the third fixed contact corresponds to the ignition ON position.
In the ACC position, the movable contact 24a is the second fixed contact 2
4c, but in the ON position, the movable contact 24a contacts the second and third fixed contacts 24c, as shown by the broken line.
24d. The second fixed contact 24c is connected to the illumination lamps 11 and 12. The third fixed contact 24d is connected to an ignition device (not shown) and is also connected to the illumination lamps 13 to 15 via a lighting switch 25. Further, the power supply voltage output from the fuse 23 is used as a power source for the timepiece 5 via the fuse 26.
Note that the battery 22 is configured to be charged by the output of an alternator (not shown) that generates electricity in synchronization with the rotation of the engine.

In the lighting device according to the present invention having such a configuration, when the selection position of the key switch 24 is operated from the OFF position to the ACC position, the movable contact 24
a and the second fixed contact 24c contact and the battery 2
2 is applied to the illumination lamps 11 and 12 via the fuse 23 and the switch 24, and the illumination lamps 11 and 12 are turned on. This illuminates the trip meter 4, the clock 5 and the radio display 6. Next, the selection position of the key switch 24 is set to ACC.
When the key is further operated from the position to the ON position, the movable contact 24a contacts the third fixed contact 24d while contacting the second fixed contact 24c. Therefore, the illumination lamps 11 and 12 continue to be lit, and the output voltage of the battery 22 is supplied to the ignition device. this
Lighting switch 2 in the ON position selection state
5 is turned on, the output voltage of the battery 22 is applied to the lighting lamps 13 to 15, and the lighting lamps 13 to 15 are also turned on. and is illuminated together with the radio display 6.

Further, in the embodiment of the present invention described above, the illumination lamps 11 to 15 are provided on the instrument panel 1, but each instrument panel may be provided with an illumination lamp. Further, the lighting element is not limited to a lamp, and for example, a light emitting diode may be used.

Effects of the Invention As described above, in the instrument panel illumination device of the present invention, the clock, which is one of the accessory instruments, can be illuminated by a simple single switch operation. In addition, after the engine has stopped, only the accessory gauges can be illuminated without turning on the unnecessary operating state gauges, headlamps, and taillights, which prevents unnecessary battery consumption and allows accessory gauges to be used for long periods of time. lighting is possible.
