Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hazard lamp device, and particularly to a hazard lamp device that can be activated even if a driver encounters an unexpected situation.

[Conventional technology]

2. Description of the Related Art Hazard lamp devices have conventionally been known that cause hazard lamps to flash when a driver operates a hazard lamp switch provided on an instrument panel or steering column of an automobile. According to this, it is possible to draw the attention of drivers of other vehicles during emergency parking or the like.

[Problem to be solved by the invention]

However, with such conventional devices, in order to make the hazard lamps flash, the driver is inevitably required to manually operate the hazard lamp switch, so it is difficult to perform such an operation. In other words, in the event of an unexpected situation such as a rear-end collision where the driver has lost consciousness or has an injury that makes it impossible for the driver to operate the vehicle, the problem is that the hazard lights cannot be activated to flash. Ta.

Therefore, it may draw the attention of following vehicles, and may cause an accident such as a secondary collision, especially at night or under bad weather.

Incidentally, in recent years, airbag systems have been developed to avoid danger to drivers in the event of a car collision.

In this airbag system, a predetermined activation signal is issued when an impact or the like on a vehicle is detected, and the activation signal is used as an input to activate an airbag detonator. This type of system is unique in that it was developed with the assumption that the driver would not be able to operate the vehicle.

Therefore, assuming that the driver is unable to operate the vehicle, when the airbag system whip is activated, it can be seen as an emergency situation, and it is therefore considered necessary to flash the hazard lights at the same time.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to more reliably issue an emergency warning by configuring the hazard switch to flash in response to an activation signal in the airbag system even if the driver is unable to operate the hazard switch in an unexpected situation. To provide a hazard lamp device which can be expected to avoid the causes of accidents such as collisions.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention includes a hazard lamp disposed around the automobile and at least one relay means provided to blink the hazard lamp at a predetermined timing. In the hazard lamp device, the relay means is configured to be actuable by operating a hazard lamp switch, and also to be actuable by input of an airbag system activation signal.

[For production]

In the above configuration, when the driver turns on the hazard switch, the hazard lamp relay is activated in response to this, and the hazard lamp flashes at a predetermined timing.

On the other hand, when a car causes a collision, the force of the impact generates a signal to activate the airbag system, and this signal is used as input to activate the hazard relay, causing the hazard lamps to flash in the same way as described above. Begins.

[Example] Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 1 shows a schematic block diagram of a hazard lamp device according to this embodiment. In this figure, the hazard lamp device includes a hazard lamp switch 1, a hazard lamp relay 2 as a relay means that is energized when the hazard lamp switch is in the closed state, and a hazard lamp relay 2 that is a relay means that is energized when the hazard lamp switch 1 is in the closed state. It is equipped with hazard lamp 3 that flashes at the timing of. Further, the hazard lamp relay 2 is provided so that an activation signal when the airbag system 4 is activated is inputted thereto.

To explain the above configuration in detail based on FIG. 2, the airbag system 4 includes an airbag sensor 4A that detects the impact force applied to the automobile;
Airbag controller 4 that processes the output signal of A in a predetermined manner
C, and an airbag detonator 4B that is activated in response to an output signal when the airbag controller 4B determines that the air hack should be detonated.

The airbag controller 4B is connected to a power source 6 such as a battery via an ignition switch 5, and a signal output to activate the airbag detonator 4C is also input to the hazard lamp relay 2. It has become.

In addition, the hazard lamp 3 includes four hazard lamps 3A.
, 3B, 3C, and 3D, each of which is connected to the hazard lamp relay 2.

At this time, the hazard lamps 3A to 3D are 3A, 3B, and 3.
0 and 3D are arranged as a pair on the front, rear, left and right sides of the car, but they can also be provided on the fenders and flashed on the sides of the car.

In the above configuration, when stopping the car in an emergency,
When the driver closes the hazard switch 1, the hazard lamp relay 2 is activated and each hazard lamp 3A~
3D flashes.

On the other hand, when a car is involved in a collision while driving,
The airbag sensor 4A detects the impact force, applies it to the airbag controller 4B, and when it is determined that the impact force is greater than a predetermined value, a signal for activating the airbag detonator 4C is activated. The signals are outputted to the section 4C and the hazard lamp relay 2, respectively, and at this time each hazard lamp 3A to 3D is blinked.

According to such an embodiment, by also using the activation signal of the air hack system 4, the hazard lamps 3A to 3 are activated by a route other than the closing operation of the hazard lamp switch 1.
Since D is configured to flash, even if a collision occurs in which the driver cannot operate the hazard lamp switch 1, the hazard lamp relay 2 can be activated by the impact force detection signal at that time. It is expected that this system will be able to alert drivers of cars in front of and behind them even in unexpected situations.

In addition, it does not use a separate and independent system dedicated to the operation of the hazard lamp relay 2 through a separate route as described above, so manufacturing costs can be kept low and it can be easily applied to existing systems. This has the effect of providing a highly versatile hazard lamp device.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and may be configured as shown in FIG. 3, for example.

That is, in the above embodiment, the power supply 6 and the hazard lamp relay 2 were configured as one each, but each sub power supply 10. It is also possible to provide a sub-hazard lamp relay 11 as a relay means, and to apply an activation signal for the airbag system to the sub-hazard lamp relay 11 so that each of the hazard lamps 3A to 3D blinks.

At this time, power supply 6. Connect the hazard lamp relay 2 to the front of the car, and connect the sub power supply 10. If the sub-hazard lamp relays 11 are installed at the rear, the front power source 6. Even if the hazard lamp relay 2 cannot function due to damage etc., the rear power supply 10. The sub-hazard lamp relay 11 is advantageous in that it can function and provide a flashing display to the rear vehicle more reliably.

In addition, as shown in FIG. 4, a sensor 12 for detecting impact from the front, rear, left and right sides of the automobile is provided in place of the airbag system 4 shown in FIG. Alternatively, each of the hazard lamps 3A to 3D may be blinked.

[Effects of the Invention] Since the present invention is configured and functions as described above, even if the driver falls into an unexpected situation in which he or she cannot operate the hazard switch, the hazard switch can be made to flash by the activation signal in the airbag system. It is possible,
This has the effect of providing a hazard lamp device that can be expected to more reliably issue a warning in an emergency.
