Description

[Detailed explanation of the idea] The present invention relates to a headlamp device for a motorcycle.

Generally, vehicle headlights are often used as a substitute for simple illumination during nighttime work.
However, since headlights are commonly installed on vehicles, it is natural that work is limited to the direction of the headlights, and they are not suitable when the work area is frequently moved. There is no denying that.

Therefore, the present invention was devised by focusing on the above-mentioned problem, and the headlight is made detachable from the vehicle body so that only the headlight can be moved at any time to the desired irradiation location as a work light. The purpose is to provide lighting equipment.

The headlight device of the present invention comprises a circuit including a high beam input line, a low beam input line and a common input line from a high beam lamp and a low beam lamp of a motorcycle headlamp, a power supply and a beam changeover switch. The high beam output line, low beam output line, and common output line from and a sub-cord connector that forms a connector pair with one of the pair of connectors on the headlight side, and the sub-cord connector relays the output voltage of the spare battery to the one connector when coupled with one of the connectors. It is characterized by

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described in detail with reference to the accompanying drawings. FIG. 1 shows a buggy vehicle, which is a vehicle exclusively for off-road use, to which the headlight device of the embodiment is applied. The headlight 1 is detachable from the vehicle body A, and is conveniently carried by a handle provided on the case 1a as shown in FIG. case 1a
Inside, there are built-in members forming a lighting circuit, an electric wire cord 1b, etc., which will be described below.

3a and 3b are an electric circuit diagram when the headlamp 1 is attached to the vehicle body A, and an electric circuit diagram when the headlamp 1 is removed from the vehicle body A and used as a work light.

In Fig. 3a, when installed, 1a in the figure is the case explained in Fig. 2, and the inside of this case has a so-called downward Lo beam and an upward Lo beam, depending on the height of the projection distance and range of the projected light. A lamp body 2 consisting of lamps L ₁ and L ₂ differentiated for Hi beam, and this lamp body 2
An auxiliary battery 3 connected to each of the lamps L ₁ and L ₂ is built-in. The terminals of the lead wires forming these circuits are connected to the vehicle power source 8 and ground 9 via disconnectable connectors 4 and 5 and a switch box 7 arranged around the steering wheel 6 of the vehicle body A and forming a switching circuit. be done. The vehicle power source is composed of a battery 8 and a generator 11.

In the switch box 7, there is a switch that turns on and off the power from the battery 8.
_SW1 and a beam switching switch _SW2 for lighting either the Lo beam lamp _L1 or the Hi beam lamp _L2 .

Here, a pair of detachable connectors 4, 5
A pair of connection terminals a ₁ to _{a 4} and b ₁ to b ₄ are provided at corresponding positions, respectively, and the lamps L ₁ ,
A first line as a common input line that is commonly connected to one input terminal of L ₂ is connected to one terminal a ₁ of the connecting terminal pair a ₁ , b ₁ and the other terminal of the lamps L ₁ , L _{2 .} A second line as a high beam input line and a third line as a low beam input line _which respectively connect the input terminals separately connect each terminal a 2 , one of the connecting terminal pairs a ₂ , b ₂ and a ₃ , b ₃ . Connected to _a3 .
The 7th line as a common output line from the ground 9 is connected to the connection terminal b ₁ of the connector 5, and the 8th line as the high beam output line from the Hi beam selection side contact of the switching switch SW ₂ is connected to the connection terminal.
b ₂ and the 9th line as the low beam output line from the Lo beam selection side contact of switching switch SW ₂ .
The line is connected to connection terminal _B3 .

Regarding the pair of connection terminals a ₄ and b ₄ provided in the connectors 4 and 5, both side power terminals of the auxiliary battery 3 built in the case 1b connect to the fourth line connected to the first line and the connection terminal. vs. a ₄ , b ₄
are connected via the fifth line connected to one terminal _A4 of the terminal A4. And the connection terminal pair a ₄ , b ₄
The other terminal _b4 is connected to the power supply side of the switching circuit via the sixth line. Note that the regulator 10 is connected to the sixth line, which is connected to the battery 8 which is the vehicle side power source.
It is not necessary if the rated voltages of the and auxiliary battery 3 are the same, and if the voltage of the vehicle side battery 8 is high, the regulator 1 is used as a step-down rectifier.
0 is incorporated.

On the other hand, FIG. 3b shows an electric circuit when the headlight 1 is removed from the vehicle body A and used as a work light. That is, when the mechanical connection between the headlight 1 and the vehicle body A is separated, the pair of connectors 4 and 5 are separated. Another sub-cord connector 12 is detachably attached to the disconnected lamp body side connector 4 when turning on and off the light. The structure of the sub-cord connector 12 is as shown in FIG. 3c, in which terminals c ₁ to c ₄ are provided.
Connecting terminal pairs are formed in correspondence with terminals a ₁ to _{a 4} of . Among the terminals c ₁ to _{c 4} , terminal c ₄ and terminals c ₂ and c ₃ are connected internally, and the sub-cord connector 12
When assembling, the fourth and fifth lines connected to the auxiliary battery 3 in the case 1a are connected to the second and third lines connected to the lamps L ₁ and L ₂ , and both lamps are connected. The configuration is such that a closed circuit is formed so that L ₁ and L ₂ are lit at the same time.

In other words, subcode connector 1 is connected to connector 4.
2, the output voltage of the spare battery 3 is applied between both terminals of each lamp L ₁ and L ₂ via the line in the sub-cord connector 12 (dashed line in Figure 3 c), so the headlight When the headlamp 1 is removed from the vehicle body A, the lamps L ₁ and L ₂ of the headlamp 1 can be turned on by the output voltage of the spare battery 3.

As understood from the description of each example above,
According to the present invention, the following effects can be expected. That is,
By making the light body removable from the vehicle body and storing the light body itself in a compact case together with a power supply battery, it is extremely effective as a simple night work light for, for example, deep plowing work. Also,
Another major feature of this invention is that the lamp's power battery is constantly charged while the vehicle is running.
