Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to a flasher circuit for a vehicle that stops the hazard operation when a forward direction indication operation is performed during the hazard operation.

(b) Prior art Automobiles have traditionally been equipped with hazard lights to notify other vehicles that they have stopped in an emergency due to a breakdown, etc., and are particularly effective when stopping on expressways or at night. . An example of a conventionally used hazard circuit is shown in Figure 2.
Published in May, No. 484), page 368.
In this hazard circuit, the flasher unit 4 is connected to the battery 1 via the hazard switch 3, and when the hazard switch 3 is switched to the OFF side, for example, the ignition switch 2 and the flasher unit 4 are connected to each other. configured to be connected. When the hazard switch 3 is switched to the ON side, the flasher unit 4 is connected to the battery 1 regardless of the operation of the ignition switch 2, and the input and output are intermittently turned on and off. By this on/off operation, the flasher lamps 5 and 6 and the indicators 8 and 9 are intermittently connected to the battery 1 and blink. The flasher lamp 5 is a direction indicating lamp provided at the front and rear ends of the right side of the vehicle, and the flasher lamp 6 is provided at the front and rear left side of the vehicle.
These flash at any time to warn outsiders that the vehicle is in an emergency stop.

Flasher unit 4 is hazard switch 3
It is connected to a battery 1 via an ignition switch 2, and to flasher lamps 5 and 6 via a turn signal switch 7. This causes ignition switch 2 to
Turn signal switch 7 is on the left (L) when it is ON.
When the switch is switched to the right side (R), the output of the flasher unit 4 is supplied to the left flasher lamp 6 and the indicator 9, causing these lamps to flash; when the switch is switched to the right side (R), the output from the flasher unit 4 is supplied to the left flasher lamp 6 and the indicator 9, and when the switch is switched to the right side (R), the output from the flasher unit 4 is supplied to the left flasher lamp 6 and indicator 9, causing these lamps to blink. Make indicator 8 blink.

(c) Problems to be solved by the invention In general, in a flasher circuit, the flasher lamps 5 and 6 are used for direction indication and stop warning, so for example, a hazard lamp may be flashed on the left side of the road. Like when you start from a stopped state and move towards the center of the road.
When driving to the right or left from a stopped state, turn the turn signal switch 7 to the right (R) position, for example.
Even if you operate the vehicle to indicate direction, the blinking state of the flasher lamp remains the same as before, so there is a problem in that you cannot send a signal to the rear to change direction, turn right, or turn left.

(d) Purpose and structure of the invention This invention was created in view of the above points, and its purpose is to ensure that a direction indication signal is given when a direction indication operation is performed during a hazard operation. In order to achieve this purpose, we use an automatic reset type hazard switch that stops the hazard operation when the direction indication is operated during the hazard operation, and then stops the hazard operation even if the direction indication operation is released. It was configured to continue.

(e) Examples The present invention will be explained below based on the drawings.

FIG. 1 shows an embodiment of a flasher circuit according to the present invention, in which the same components as in FIG. 2 are denoted by the same reference numerals.

In this embodiment, when a direction indicating motion is performed during a hazard motion, the hazard motion is stopped and the direction indicating motion is performed. In FIG. 1, the turn signal switch 21 is provided with contacts R and L connected to the flasher lamps 5 and 6, as well as contacts 21a, 21b, and 21c. Contacts 21a and 21b are both connected to reset terminal R of RS flip-flop 24, and contact 21c is connected to battery 1. The automatic reset type hazard switch 20 is connected to the RS flip-flop 24, and when switched to the ON side, sets the flip-flop 24 to the set state.
Flip-flop 2 when switched to OFF side
4 to the reset state. flipflop 24
The output of is supplied to the relay 25, and this relay 25
Open and close. When flip-flop 24 is in the set state, relay 25 is closed, and FIG. 1 shows this open state. This state indicates that a hazard or emergency flashing operation is in progress, and the output of the flasher unit 4 is supplied to the flasher lamps 5 and 6 via this relay 25.

When the turn signal switch 21 is switched to the L side or the R side in this state, the contact 21c comes into contact with either 21a or 21b, and as a result, the positive voltage from the battery 1 is applied to the reset terminal of the flip-flop 24, and the flip-flop 24 is reset. state. As a result, the relay 25 is opened, the hazard operation is canceled, and only one of the flasher lamps 5 or 6 selected by the turn signal switch 21 starts blinking.

(c) Effects of the invention As explained above, with the present invention, even when the direction indication is operated during a hazard operation, the direction indication operation can be performed reliably, and the direction indication operation can be performed reliably, and the direction indication operation can be performed reliably, and the direction indication operation can be performed without fail to inform the rear vehicle of changing course, turning right, or turning left. Signals can definitely be made.
