    Brake warning device using brake oil pressure
    The present invention relates to a Quick Braking Warning System Utilized with Brake Oil Pressure.
    In a conventional vehicle, a braking lamp that is lit when braking is provided. This brake light is provided at the rear of the brake pedal and is turned on and off by a brake switch which is connected when the brake pedal is pressed. The brake light is installed at the rear of the vehicle so that the rear vehicle can grasp the braking state of the front vehicle.
    However, since the driver of the rear vehicle cannot quickly grasp the state of the braking state of the front vehicle by the lighting of the braking lamp as described above, there is a great risk of a collision accident, especially under sudden braking.
    In general, on the highway, the driver turns on a flashing light in which both direction indicators flash at the same time to prevent such a condition, which is almost impossible for a beginner or an experienced driver under urgent circumstances. You are in a very embarrassing and dangerous situation.
    An object of the present invention is to provide a rapid braking warning device using the brake oil pressure that can be automatically flashed when the instantaneous pressure of the brake oil increases during sudden braking.
    1 is a hydraulic circuit diagram of an electric circuit addition showing the overall configuration of the present invention.
    Explanation of symbols for main parts of the drawings
    1: master cylinder, 2: wheel cylinder, 3: pressure sensing valve, 4: flashing light, 5: switch, 6: time extension timer, 7: rubber diaphragm, 8: rod, 9: spring
    Referring to the accompanying drawings, the configuration of the present invention for achieving the above object is as follows.
    The present invention basically installs a pressure sensing valve (3) which can be operated at the momentary peak pressure of the brake oil by braking by branching the oil line (L) between the master cylinder (1) and the wheel cylinder (2), In the circuit of the flashing light 4, a switch 5 which can be closed by the operation of the pressure sensing valve 3 and a time extension timer 6 for continuing the flashing of the flashing light 4 for a predetermined time are provided. will be.
    More specifically, the pressure sensing valve 3 includes a rubber diaphragm 7 which operates in contact with the brake oil pressure in the middle, a rod 8 that is pushed along with the operation of the diaphragm 7, and the rod 8. And a spring 9 for returning the diaphragm 7 therein. The actuation force of the rubber diaphragm 7 of this pressure sensing valve 3 is given by the instantaneous peak pressure at which brake oil appears during rapid braking. Relatively, the spring 9 should have a spring constant which can be compressed by the peak pressure at this moment.
    The switch 5 has a fixed terminal, which can be contacted by the rod 8, between the battery 10 and the input of the time extension timer 6, and the output of the time extension timer 6 to the flashing light 4. It is connected.
    According to the above configuration, when the brake pedal 11 is pressed down as a response input for obtaining a normal braking force, the brake oil acts only on the wheel cylinder 2 in the master cylinder 1. However, when the brake pedal 11 is pressed in a sudden braking state, the instantaneous peak pressure of the brake oil activates the rubber diaphragm 7 of the pressure sensing valve 3 to push the rod 8 out. Accordingly, the lower end of the rod 8 makes contact with the fixed terminal of the switch 5 to close the circuit, so that the time extension timer 6 receives the signal to extend the current of the battery 10 for a predetermined time and blinks. Supply to (4). The flashing light 4 continues to flash until the operation of the time extension timer 6 is completed.
    In the state where the momentary peak pressure of the brake oil is released, the rubber diaphragm 7 and the rod 8 are returned by the spring 9. And the flashing light (4) only blinks for a given time in the time extension (6) and then goes out.
    In the present invention, since the flashing light is automatically flashed by the pressure of the brake oil during sudden braking, the driver does not need to find a flashing light switch when the driver is embarrassed, thereby reducing the risk of an accident. By immediately grasping and taking a choke to prevent collision accidents will contribute to the prevention of collision accidents.
