Description

[Detailed description of the invention] [Industrial application field] The invention relates to a headlight control device for a motorcycle that is lit even in the daytime.

[Conventional technology]

Motorcycle headlights have a high beam and a low beam, the high beam can be irradiated to a distant place, the low beam can be irradiated to the near part, the low beam when there is an oncoming vehicle, the driver of the oncoming vehicle is not dazzling In this way, the driver can appropriately switch with a dimmer switch. By the way, in motorcycles, in order to clarify the existence of oneself and to make driving safe,
The headlights are turned on even in the daytime.

[Problems to be solved by the invention]

When the headlights are turned on in the daytime, the surroundings are bright, so the driver does not know whether the headlights are high beams or low beams. This can only be confirmed by the position of the dimmer switch, which is often lit with a high beam. On the other hand, the oncoming vehicle has a problem that even if it is in the daytime, if the opponent turns on the headlights with the high beam, they can directly see and feel dazzling, which is inconvenient.

To solve this problem, it is conceivable to provide an optical sensor at the top of the vehicle so as not to turn on the high beam in the daytime. However, if the light sensor is simply provided at the top of the vehicle, the light sensor may malfunction due to light other than daylight. For example, at night, there is a problem that the light sensor malfunctions due to light from the indicator lamp of the instrument panel or light from the side, so that even if the light sensor is turned on with a high beam, it becomes a low beam.

In view of this point, the present invention prevents the light sensor from malfunctioning with light other than daylight, and, in order to clarify its own existence, turns on the daylight switch when the headlight is turned on in the daytime. It is an object of the present invention to obtain a motorcycle headlight control device that is lit by a low beam and does not give glare to oncoming vehicles regardless of the position of the vehicle.

[Means for solving the problem]

In order to solve the above-mentioned problem, the present invention provides a speedometer at the center of a handle (1) provided with grips (1a, 1a) at left and right ends.
In a motorcycle headlight control device provided with an instrument panel (2) such as a fuel gauge, a headlight (6) having a high beam (7) and a low beam (8) is switched by a dimmer switch (11). A control circuit (14) is inserted between the high beam contact (12) of the mar switch (11) and the headlight (6), and the light sensor (4) and the high beam that receive at least upward light in the control circuit (14). (7) Connect the relay (16), which is switched to either the low beam (8) or the low beam (8). Even if the dimmer switch (11) is turned on to the high beam contact (12), the light sensor (14) will be in daylight. The low beam (8) is turned on by the relay (16) while the light is received, and goes to the back side of the instrument panel (2) at one corner (2a) of the corner of the instrument panel (2). A concave portion (3) is provided. The optical sensor (4) is housed and arranged at the central bottom part (3a) of the part (3), and on the front side of the instrument panel (2), it surrounds the recess (3) and the instrument panel (3). 2) A headlight control device for a motorcycle, comprising an enclosure (5) extending toward a transparent cover body (20) covering a surface (2c).

[Action]

According to the present invention, a headlight having a high beam and a low beam is switched by a dimmer switch, and a control circuit is inserted between the high beam contact of the dimmer switch and the headlight, and at least upward light is supplied to the control circuit. The low beam is lit by the relay while the light sensor is receiving daylight, even if the light sensor to be received is connected to a relay that switches to either the high beam or low beam and connected to the high beam contact even if the dimmer switch is turned on to the high beam contact Is what you do.

Therefore, in the daytime, the light sensor receives daylight and energizes the control circuit to the low beam side of the headlight. Therefore, even if the dimmer switch is turned on to the high beam contact side, the headlight is turned on with the low beam, so that the driver of the oncoming vehicle can be prevented from dazzling.
At night, the function of the light sensor is stopped, and the headlights can be switched appropriately with a dimmer switch.

In addition, a recess is provided at one corner of the corner portion of the instrument panel toward the back side of the instrument panel, and an optical sensor is stored and arranged at the center bottom of the recess, and the front side of the instrument panel surrounds the recess. In addition, since the enclosure extending toward the transparent cover body covering the surface of the instrument panel is provided, light incident on the optical sensor from the side is blocked (blocked) by the enclosure and the concave portion and reaches the optical sensor. Instead, the light sensor operates only with light coming from above the instrument panel. Therefore,
The optical sensor does not malfunction.
