[Structure] A hazard lamp lighting circuit that blinks the hazard lamps when operated by the driver includes means for detecting the stoppage of the internal combustion engine, and a timer circuit that is activated by the detection output and cuts off the current to the hazard lamps after a predetermined period of time has elapsed. Be prepared. [Effect] Battery consumption can be reduced when the hazard lamp flashes for a long time.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is used to turn on the hazard lights of automobiles. This invention is a hazard lamp The present invention relates to a hazard lamp lighting circuit that stops lighting of a hazard lamp after a predetermined period of time.

0002

[Conventional technology]

FIG. 2 is a block diagram showing the configuration of a conventional example. This kind of circuit is available in Japanese Patent Application No. 62-18194. As disclosed in Publication No. 0, hazard lamp circuit 11, turn signal switch There is one equipped with a switch 2, an intermittent circuit 4, and a hazard switch 13.

0003 This circuit operates when the key switch 6 is turned on when the hazard switch 13 is in the ON state. When the power supply 10 is turned on, the current from the power supply 10 flows through the ON contact of the hazard switch 13, the disconnection circuit 4 and The flow passes through the ON contact of the hazard switch 13 to the hazard lamp circuit 11, and on the other hand, the hazard If the key switch 6 is turned on while the key switch 13 is in the OFF state, the power supply 10 is turned on. These currents flow through the OFF contact of the hazard switch 13, the intermittent circuit 4, and the turn signal. The signal flows to the hazard lamp circuit 11 through the red switch 2, causing the hazard lamp to flash. There is.

[Problem that the idea aims to solve]

Conventional hazard lamp lighting circuits like this operate even when the internal combustion engine is stopped. , the hazard switch is configured so that it continues to flash when it is in the on state. However, if this condition lasts for a long time, power generation will not occur and the electricity will be lost. There is a problem in that power consumption increases and the battery becomes unusable. for example, If the engine is stopped, the hazard lights are activated, and the driver leaves the vehicle for some reason, If you are unable to return to your vehicle, the battery may run out when you return to your vehicle. If it is stuck, the engine may not start.

[0005] This invention solves this problem by stopping the internal combustion engine and waiting for a predetermined period of time. A circuit that can automatically stop the current supply to the hazard lamp when The purpose is to provide.

[0006]

[Means to solve the problem]

This invention includes a hazard switch located in the driver's seat. To the hazard lamp lighting circuit that supplies intermittent current to the hazard lamp by operation of a means for detecting the stoppage of the internal combustion engine, and a means for detecting the stoppage of the internal combustion engine; and a timer circuit that automatically cuts off the intermittent current after a certain period of time. do.

[0007]

[Effect]

When it is detected that the key switch is turned off and the internal combustion engine has stopped, the timer starts. The circuit starts, and after a predetermined period of time (for example, in the range of 10 minutes to 120 minutes), the intermittent circuit The hazard lamps stop blinking by cutting off the current to the

[0008] As a result, even if the driver uses the hazard lights for a long time, they will not flash. Excessive power consumption due to continuous operation can be prevented, and the battery can retain its stored power. This can prevent the device from becoming unusable due to deterioration.

【Example】

Next, an embodiment of the present invention will be described based on the drawings. Figure 1 shows the configuration of the embodiment of the present invention. FIG.

0010 The embodiment of the present invention includes a hazard lamp circuit 1 and a hazard lamp placed in the driver's seat. Hazard switch 3 that supplies operating current to circuit 1 and flashes the hazard lamp. an intermittent circuit 4 that intermittents the supply current in order to The present invention also has an operating current supply circuit 5 that provides a key switch. Internal combustion engine stop detection that detects the stop of the internal combustion engine by detecting the off state of 6. It is activated by means 7 and the detection output of this internal combustion engine stop detection means 7, for example, for 10 minutes. After a predetermined time period of 120 minutes has elapsed, the operating current supply circuit 5 is turned off. A timer circuit 8 that cuts off the current to the intermittent circuit 4, a hazard switch 3, and a tie The timer cancel switch 9 is provided to connect/disconnect the timer circuit 8.

[0011] Next, the operation of the embodiment of the present invention configured as described above will be explained.

0012 In normal hazard operation, current is supplied from the power supply 10 to the hazard switch 3, and the When the driver operates this hazard switch 3, the hazard lamp circuit 1 is activated. The output of the intermittent circuit 4 is received to cause the hazard lamp to blink.

[0013] At this point, the key switch 6 changes from the on state to the off state, that is, the internal combustion engine is stopped. In the stopped state, the internal combustion engine stop detection means 7 detects this off state. timer times The timer circuit 8 sends the detection output to the circuit 8, and receives the detection output. When a predetermined period of time has elapsed, the operating current supply circuit 5 is operated and turned off. automatically cuts off the current supply to the intermittent circuit 4. This allows the The intermittent blinking of the hazard lamps that exceeds a predetermined time is stopped.

[0014] At the discretion of the driver, it may be necessary to keep the hazard lights flashing even after the specified time has passed. In some cases, the timer cancel switch 9 is turned on and the operating current supply circuit 5 is turned on. can be brought into contact. Also, when you want to stop the timer operation regardless of the elapsed time. In this case, the timer cancel switch 9 is turned off and the operating current supply circuit 5 is disconnected. can be made into a state.

[0015]

[Effect of the idea]

As explained above, according to the present invention, a predetermined period of time elapses while the internal combustion engine is stopped. Since the current supply to the hazard lamp circuit is automatically cut off when the The flashing of the headlight lamp will no longer continue beyond the specified time, and this will prevent excessive flashing. It is possible to reduce power consumption and prevent the battery from becoming unusable. There is an effect that can be done.
