Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to automobile cornering.
Use for lamps. The cornering lamp is a headlight which is provided separately from a general headlamp and whose irradiation direction is set to the left and / or right of the traveling axis direction of the automobile. The present invention relates to a circuit for lighting the cornering lamp in conjunction with a direction indicator operation switch.

[0002]

2. Description of the Related Art A lighting circuit for a cornering lamp of an automobile operates in a state where a general headlamp is lit and when a direction indicator operation switch is operated, the cornering lamp in the operation direction is interlocked. It is configured to automatically light up. That is, if the direction indicator operation switch is operated to the left while the headlamps are on at night and the general headlamps are lit, the cornering with the irradiation direction set to the left without any special operation. When the lamp is turned on and operated to the right, the cornering lamp whose irradiation direction is set to the right is also turned on. In the conventional device, the cornering lamp is automatically extinguished when the direction indicator operation switch returns to the neutral point. In the case of a structure in which the direction indicator operation switch returns in conjunction with steering operation, the direction indicator operation switch does not operate in principle and returns to the neutral point, so the cornering lamp does not require special operation. However, it is configured to automatically turn off the lights in conjunction with this. Further, the cornering lamp may be installed only on the left side (vehicle for a country of left-hand traffic) or only on the right side (vehicle for a country of right-hand traffic), and the present invention also includes such a case.

[0003]

In this conventional device, when the steering operation is returned to the return state, the operation switch for the direction indicator is immediately returned to the neutral point and the direction indicator lamp is extinguished, so that the cornering lamp is a little further. Even if you want it to stay lit continuously, it will go out automatically. Generally, when the steering operation enters the return state, the vehicle is still turning, and even if the direction indicator operation switch returns to the neutral point,
It is desirable that a turn signal lamp for notifying a driver or a pedestrian of another vehicle of the traveling direction of the vehicle and a cornering lamp for irradiating the direction of rotation of the vehicle are kept on for a while. In such a case, the driver operates the direction indicator switch again while the vehicle is turning.

On the other hand, when the traveling lane is changed while the vehicle is traveling in a straight line or when the vehicle traveling ahead is completed, the steering operation amount may be small and the operation switch for the direction indicator may not automatically return. In such a case, the driver forcibly returns the direction indicator operation switch to the neutral position by operation. In this case, it is not necessary to continue turning on the turn signal lamp and the cornering lamp for a while after the return.

The present invention has been made against such a background, and provides a convenient device for delaying the turn-off of a turn signal lamp and a cornering lamp for a while after the operation switch for a turn signal is automatically returned. The purpose is to do.

[0006]

SUMMARY OF THE INVENTION The present invention provides a cornering lamp lighting circuit for lighting a cornering lamp in conjunction with the operation of a direction indicator operation switch, wherein the operation switch is operated from the left or right operation state. It is characterized in that it is provided with a delay circuit which is activated when returning to the neutral point and holds the lighting state of the turn signal lamp and the cornering lamp for several seconds. It is desirable to include means for inhibiting output of the delay circuit when the operation switch is returned to the neutral point by operation.

[0007]

When the operating switch for the direction indicator is returned to the neutral point, the delay circuit operates for a few seconds, and the turning on of the direction indicator lamp and the cornering lamp is substantially continued. This several seconds is practically about 2 to 5 seconds, although it depends on the length of the wheel base of the vehicle, that is, the turning performance and the traveling speed of the vehicle. When the driver forcibly returns to the neutral position by operating the direction indicator operation switch without synchronizing with the steering operation, for example, when steering the steering operation, such as when the preceding vehicle has been overtaken or the lane has been changed. When the angle is small, in such a case, the extended lighting by the delay circuit is basically unnecessary.

Since the lighting circuit of the present invention is a circuit for lighting the turn signal lamp and the cornering lamp for a longer period of time than before, the lighting is ensured until the vehicle completes the right and left turns.

A delay circuit 6 for holding the lighting state of a or 3b is provided. This circuit includes a delay circuit 6 when the direction indicator operation switch 1 is returned to the neutral point by the driver's operation.
Means for prohibiting the operation of are included.

The direction indicator operation switch 1 and the self-return detector 2 are provided on the outer periphery of a handle shaft 8 having a protrusion 8a as shown in FIG. 4, and the self-return detector 2 is provided with switches 2a and 2b. . Right / left turn detection switches 11a and 11 for cornering lamps
As shown in FIG. 5, b is a conductive moving contactor 11c having a long hole for slidably inserting a pin 11g that moves in conjunction with the lever 1a, and a space where the moving contactor 11c can move. And an insulating outer frame 11h having Further, the outer frame 11h is provided with electric contacts 11d, 11e, and 11f that come into contact with the moving contact 11c.

Next, the operation of the main part of the embodiment of the present invention thus constructed will be described.

In FIG. 1, when the direction indicator operation switch 1 is operated to the left or right, the direction indicator relay 4 sends its operation signal to the cornering lamp relay 5 to indicate the left or right direction. The instrument lamp 7a or 7b and the cornering lamp 3a or 3b are turned on. When the direction indicator operation switch 1 returns to the neutral point, it is determined whether the self-return detector 2 has returned due to the steering operation or has been forcedly returned by the driver's operation. When it is determined that the vehicle has automatically returned according to the steering operation, it is determined that the steering operation has been performed corresponding to the bending state of the road, and the trigger signal is transmitted to the delay circuit 6 via the direction indicator relay 4. .
Due to this trigger signal, the delay circuit 6 causes the turn signal lamp 7a or 7b and cornering
A signal for holding the lighting state of the lamp 3a or 3b is transmitted.

When it is determined that the operation switch 1 for the direction indicator has been forcibly returned by the driver's operation, the overtaking or lane change that does not require the traveling direction to be illuminated by the cornering lamp 3a or 3b is completed. As a result, the irradiation delay operation by the delay circuit 6 is prohibited.

Thus, the operation switch 1 for the direction indicator
It is possible to classify the operation contents of the above and extend the irradiation time of the road surface by the cornering lamp 3a or 3b at the time of steering operation so that the front can be surely confirmed.

In the above example, the operation switch 1 for the direction indicator
The circuit that disables the delay circuit 6 when the driver is forcibly restored by the operation of the driver has been described, but the delay circuit 6 is disabled when the light switch (headlight) is not turned on in the daytime. Can also be configured. In that case, the delay operation according to the present invention becomes effective only when the light switch is turned on at night. Further, a switch circuit for temporarily disabling the delay circuit 6 by the driver's operation may be provided so that the presence or absence of the delay operation can be selectively used according to the driver's judgment.

Here, the delay operation of turning on the cornering lamp in the embodiment of the present invention will be described in detail with reference to FIGS. 3, 6 and 7. FIG. 6 is a diagram showing the relationship between the handle shaft and the lever when the handle is returned to the left from the right turn operation in the embodiment of the present invention, and FIGS. 7 (a), 7 (b) and 7 (c) are the right views in the embodiment of the present invention. It is a figure explaining operation of a left turn detection switch.

The light circuit 9 is operated in the ON state when traveling at night. When the operation switch 1 for the direction indicator is set to the position indicating the right turn direction, the cornering lamp 3a
The right and left turn detection switches 11a and 11b of 3 and 3b and the right and left turn detection switches 12a and 12b of the turn signals move in the arrow direction shown in FIG.

At this time, the right and left turn detection switches 11a and 11b move the moving contact 11c to the position shown in FIG. 7B as the pin 11g moves from the position shown in FIG. 11d and the electrical contact 11e are electrically connected.

When the light circuit 9 is turned on by this movement, both the cornering lamp 3b and the turn signal lamp 7b are turned on and the right / left turn detection switch 1 is turned on.
The electrical contacts 11d and 11e of 1a and 11b are electrically connected via the moving contact 11c.

The switches 2a and 2b are provided on the self-return detector 2 of the lever 1a, and when the handle shaft 8 rotates to return the lever 1a, the protrusion 8a is provided.
Corresponds to the switch 2a or 2b to form an electric circuit. On the other hand, when the lever 1a is forcibly returned by the manual operation instead of the handle, the projection 8a is not moved by the switch 2
It does not hit either a or 2b.

When the switches 2a and 2b are closed to form an electric circuit, the delay circuit 6 starts to operate for a predetermined time (several seconds).
Only turn signal relay 4 and cornering lamp
Supply current to the relay 5.

When the direction indicator operation switch 1 returns to the neutral position, the right and left turn detection switches 11a and 11b move the pin 11g to the center as shown in FIG. 7 (c), but leave the moving contact 11c unchanged. Left in place,
The electrical connection between the electric contacts 11d and 11e and the moving contact 11c is maintained as it is. At this time, in a state in which the cornering lamp relay 5 and the turn signal relay 4 are not operating, the cornering lamp 3b and the turn signal lamp 7b are extinguished.

The fact that the direction indicator operation switch 1 is forcibly returned to the neutral position manually means that the driver will not perform a right turn (or left turn) operation, for example, when overtaking is completed. However, even if the cornering lamp 3b and the turn signal lamp 7b are extinguished immediately, there is no problem in driving operation.

When the steering wheel 1 is set to the right turn direction and the steering wheel is returned to the left after the right turn operation is performed, the projection 8a provided on the handle shaft 8 hits the switch 2a as shown in FIG. , Tries to return the lever 1a of the operation switch 1 for the direction indicator to the neutral position. At that time, the self-return detector 2 is turned on, and current is supplied to the delay circuit 6 via the switch 2a.

When the delay circuit 6 is supplied with a current, the built-in timer operates for a predetermined time to supply an exciting current to the cornering lamp relay 5 and the direction indicator relay 4 to turn on the built-in switch. To At this time, the right and left turn detection switches 11a and 11b are connected to the lever 1a.
Is returned to the neutral position, the electric contacts 11d and 11e are in the state shown in FIG.
The electrical connection state is maintained via the. Therefore, even if the left / right turn detection switches 12a and 12b are turned off by the lever 1a being returned to the neutral position, the right / left turn detection switches 11a and 11b, the cornering lamp relay 5, and the turn indicator relay 4 are connected. Electric current is supplied to the cornering lamp 3b and the turn indicator lamp 7b via the turning lamp 3b, and after the lever 1a is returned to the neutral position, the delay circuit 6 keeps lighting for a predetermined time, and then the lamp is automatically extinguished.

In the case of a left turn as well, the moving contacts 11c of the right and left turn detection switches 11a and 11b move in the opposite direction, and thereafter, the same operation as in the case of a right turn is performed, and the predetermined position after the lever 1a is returned to the neutral position. The time cornering lamp 3a and the turn indicator lamp 7a are turned on.

[0028]

As described above, according to the present invention, the turning-off of the cornering lamp and the turn signal lamp during the steering operation is delayed until after the operation switch for the turn signal is mechanically returned. When the vehicle is continuously turning, the irradiation of the traveling direction is continued and the turning on of the direction indicator lamp is continued, so that the front confirmation and the display of the traveling direction can be reliably performed.
