Description

[Detailed description of the invention] [Industrial application field] The present invention is a turn signal control device, in particular, a turn signal control device that displays instructions for turning left or right when a vehicle such as a motorcycle is used in combination as a side marker light. The present invention relates to a turn signal control device that controls the operation of the turn signal.

[Problems that conventional technology and ideas try to solve]

BACKGROUND ART Vehicles such as motorcycles are provided with blinkers on the front, rear, left and right sides of the motorcycle. but,
The motorcycle or the like is not necessarily equipped with a vehicle width light that indicates the width of the vehicle. In order to ensure safety under these conditions, when attempting to install new vehicle width lights on the front, rear, left, and right sides of motorcycles, etc., in order to ensure safety, it is necessary to install new vehicle width lights on the front, rear, left, and right sides of motorcycles, etc. I had to install new side lights,
There was a problem that it would be a big burden in terms of space and cost.

[Means for solving problems]

In order to solve the above-mentioned problem, the present invention lights up all the blinker lamps in a slightly dim state when the blinker lamps already installed on the front, rear, left, and right sides of a motorcycle, etc. are not blinking. By employing this configuration, side lights can be virtually mounted on the front, rear, left and right sides of a motorcycle, etc., with a simple configuration. Therefore, the turn signal control device of the present invention is equipped with a turn signal relay that repeats the closed/open state at a predetermined cycle when a voltage higher than a threshold voltage is applied, and becomes closed when a voltage lower than the threshold voltage is applied, and a turn signal relay installed on the left and right sides of the vehicle. A turn signal control device comprising at least a lamp that performs a blinking operation as a turn signal, the turn signal relay and the lamp connected in series to a power source, and causing the lamp to blink,
a vehicle width light control circuit that supplies a voltage lower than a threshold to a turn signal relay to turn on the lamp under a voltage lower than the threshold when the lamp is not in a blinking operation state; It is characterized by its use as a light.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a configuration diagram of one embodiment of the present invention, and FIG. 2 is an operational explanatory diagram illustrating the operation of the configuration of one embodiment of the present invention shown in FIG. 1.

In the diagram, 1-1, 1-2 are left lamps, 2-1, 2
-2 is the right lamp, 3 is the left turn signal switch, 4
is the right turn signal switch, 5 is the left turn signal relay, 6 is the right turn signal relay, 7 is the battery, 8
are position switches, R ₀₁ , R ₀₂ , R _b1 , R _b2
represents a resistor, and TR ₁ and TR ₂ represent transistors. In principle, each of the turn signal relays 5 and 6 is a relay contact that is inserted in series with the relay winding by a current flowing through the relay winding when a voltage higher than a threshold voltage is applied. (Normally closed contact)
open state, as a result, the current flowing through the relay winding is cut off, the relay contact returns to the closed state, and the current flows through the relay winding again, opening the relay contact. It blinks the inserted lamp (of course, if a resistor is inserted in parallel to the relay contact, the lamp will cycle between bright and dark). If a voltage lower than the above threshold is applied, the relay contact does not change to the open state depending on the current flowing through the relay winding, and the relay contact remains in the closed state. .

In Figure 1, left lamps 1-1, 1-2 in the figure
indicates a device that is attached to the left front or rear part of a motorcycle, etc., and flashes as a turn signal when the motorcycle, etc. turns to the left. Further, when the left lamps 1-1 and 1-2 are not blinked as turn signals, they are turned on in a slightly dark state as vehicle side lights to ensure safety, as will be described later. Similarly, the right lamps 2-1 and 2-2 in the figure are attached to the front or rear right side of a motorcycle, etc., and are flashed as turn signals, and when not flashed as turn signals, are slightly dimmed as vehicle side lights. It lights up depending on the condition.

In the figure, a left turn signal switch 3 and a right turn signal switch 4 are for applying voltage V _B supplied from a battery 7 to a left turn signal relay 5 and a right turn signal relay 6, respectively, via fuses. . The left turn signal relay 5 and right turn signal relay 6 to which the voltage V _B supplied from the battery 7 is applied are turned ON/OFF at a predetermined cycle.
OFF is repeated, and the left lamps 1-1, 1-2 and the right lamps 2-1, 2-2 are turned on and off as blinkers. When used as a normal blinker, the blinking is switched using a switch that can close either the left blinker switch 3 or the right blinker switch 4.

In the figure, position switch 8 is left lamp 1-
1, 1-2 and right lamps 2-1, 2-2 are used as vehicle side lights to turn on in slightly dark conditions. The position switch 8 is closed (ON)
, the voltage V _B from the battery 7 is applied to the emitters of the transistors TR ₁ and TR ₂ via the position switch 8, respectively. On the other hand, the base of each of the transistors TR ₁ or TR ₂ is
Each is connected to the current inflow point of the other fuse via a resistor R _b1 or R _b2 . Therefore, the current from the battery 7 first flows through the position switch 8, the transistor TR ₁ , the resistor R ₀₁ , the fuse,
Left turn signal relay 5 and left lamp 1-1,1
-2 to the ground point. Second, position switch 8, transistor TR ₂ , resistor
_R02 , the fuse, the right turn signal relay 6, and the right lamps 2-1 and 2-2 flow toward the ground point. Therefore, the voltage applied to the left turn signal relay 5 and the right turn signal relay 6 is the voltage V _B of the battery 7 minus the voltage drop due to the resistor R ₀₁ or R ₀₂ . The resistors R ₀₁ and R are adjusted so that the voltage applied to the left turn signal relay 5 and the right turn signal relay 6 after subtracting the voltage drop is a low voltage at which the turn signal does not turn ON/OFF. Since the value of ₀₂ is set, the left lamps 1-1, 1-2 and right lamps 2-1, 2-2 are turned on as side lamps in a slightly dark state.

Next, the operation when using the configuration shown in FIG. 1 will be explained in detail using FIG. 2.

Figures 2a and 2b show the states of the applied voltages applied to the left lamps 1-1, 1-2 and the right lamps 2-1, 2-2, respectively. In the figure, the vertical axis represents the lamp voltage applied to each lamp, and the horizontal axis represents time.

The figure shows a state in which the position switch 8 is turned on (closed state). In this state, the transistor
TR ₁ and TR ₂ are both conductive and the resistance R ₀₁
Alternatively, the voltage after subtracting the voltage dropped through R ₀₂ is transferred to the left lamp 1 - via the left turn signal relay 5 or the right turn signal relay 6, respectively.
1, 1-2 or right lamps 2-1, 2-2. Therefore, the left lamp 1-1,
1-2 and right lamps 2-1 and 2-2 are lit in a slightly dark state and serve as vehicle side lights.

The figure shows a state in which the left turn signal switch 3 is turned on (closed state) with the position switch 8 turned on. In this state, the voltage V _B of the battery 7 is directly applied to the left turn signal relay 5 via the left turn signal switch 3 and the fuse, so the left turn signal relay 5 repeats ON/OFF at a predetermined period and Turns on/off the current supplied to lamps 1-1 and 1-2. As a result, the left lamps 1-1 and 1-2 blink as blinkers. In addition, when the left turn signal switch 3 is turned on, the transistor
Since the emitter and base of TR ₂ are short-circuited, the right lamps 2-1 and 2-2 will not be turned on in a somewhat dark state as in the current situation. Furthermore, since the value of the resistor R _b1 connected between the base of the transistor TR ₁ and the fuse is large, depending on the current flowing through the resistor R _b1 , the right lamp 2-1,
2-2 is never lit.

The figure shows a state in which the left turn signal switch 3 is turned off (opened). In this state, the voltage after subtracting the voltage dropped by the resistor R ₀₁ or R ₀₂ as described above is the voltage at the left turn signal relay 5.
and is applied to the right turn signal relay 6, so
Left lamp 1-1, 1-2 and right lamp 2-1,
2-2 will be lit as a slightly dim vehicle side light.

The figure shows a state in which the right turn signal switch 4 is turned ON (closed). In this state, the right lamps 2-1 and 2-2 flash in the same manner as in the figure described above. At this time, the left lamps 1-1 and 1-2 are turned off.

The figure shows a state in which the right blinker switch 4 is turned off (opened). In this state, the voltage after subtracting the voltage dropped through the resistor R ₀₁ or R ₀₂ is the left lamp 1-1, 1-2 and the right lamp 2-1, 2, respectively, in the same way as shown in the diagram above.
-2, and is turned on as a side light in slightly dark conditions.

The figure shows a state in which the position switch 8 is turned off (opened). In this state, the battery is 7
No voltage is applied to the transistors TR ₁ and TR ₂ , respectively, and the left lamps 1-1, 1-2 and the right lamps 2-1, 2-2 are not lit. This is used during the day when there is no need to turn on the side lights. However, by turning on the left turn signal switch 3 and the right turn signal switch 4 (closed state), the left lamps 1-1, 1-2 and the right lamps 2-1, 2-2 can be made to blink.

[Effect of idea]

As explained above, according to the present invention, when the turn signal lamps already installed on the front, rear, left, and right sides of a motorcycle, etc. are not blinking, it is possible to turn on all the turn signal lamps in a slightly dim state. Since this configuration adopts a configuration that allows the vehicle to be mounted on the vehicle, the vehicle width lights can be mounted on the front, rear, left, and right sides of a motorcycle, etc., with a simple configuration.
