Description

[Detailed Description of the Invention] [Purpose of the Invention] Industrial field of application The present invention, depending on when the accelerator pedal of the automobile is released,
The present invention relates to an advance notice brake device for an automobile that lights or blinks a brake lamp.

Conventional technology In the past, the main causes of collision accidents were inattentive driving, too close inter-vehicle distance, too high speed, etc., but when you analyze the psychology of a driver (causing side) who experienced an accident during a rear-end collision , There are many cases where the former brake lamp is lit, even though it recognizes for a moment, and it has collided.

Taking a road with good traffic flow, especially a highway as an example of the cause, even if the driver recognizes that the brake light of the former is on, the driver refrains from sudden braking more than necessary considering the safety to the following vehicles. Therefore, there is a momentary discrepancy between the former and whether it is just a deceleration, which causes a slight delay in braking force and a delay, which causes a rear-end collision accident. In particular, especially for female drivers, paper drivers, and elderly drivers, the time from releasing the accelerator to applying the brake is slow on average, so the braking force will inevitably be delayed and the same as above. A rear-end collision will occur.

Therefore, JP-A-61-67643 and JP-A-6-67643
Although a device found in Japanese Patent Laid-Open No. 2-166132 has been developed, however, in this device, since the switch is directly connected to the accelerating accelerator pedal, when the foot is separated from the accelerator pedal, Due to the vibration during traveling, an external force for moving the accelerator pedal downward is directly applied, and as a result, there is a drawback that the display lamp does not turn on in advance even when the accelerator pedal is released.

DISCLOSURE OF THE INVENTION Problem to be Solved by the Invention The present invention is intended to reduce the number of rear-end collision accidents by notifying the following vehicle in advance that the braking force will be applied by turning on or blinking the brake lamp when the accelerator pedal is released. It is intended to provide a braking device.

[Constitution of device]

Means for Solving the Problems In view of the above, the present invention provides a screw or cam mechanism that converts a rotational force due to the swing of the accelerator pedal into a straight driving force in an accelerator pedal that is swingable and returns to an upward swing position. A pushing shaft for controlling the forward / backward movement in the lateral direction orthogonal to the vehicle traveling direction is provided, and switches are arranged at predetermined positions at opposite positions of one end of the pushing shaft, and the switches are turned on or blinking a brake lamp. The above-mentioned drawbacks are not solved by providing an advance notice braking device for an automobile connected to a control unit.

In the present invention, when the accelerator pedal is released, the accelerator pedal returns to the upper swing position, and accordingly, the pressing shaft is laterally moved forward and backward by the screw or the cam mechanism to control the pressing shaft. The switch is activated at one end to turn on or blink the brake lamp via the control unit.

Embodiment An embodiment of the present invention will now be described with reference to the drawings. 1 is a notice brake device for lighting or blinking a brake lamp 2 of an automobile. One of the accelerator pedal 3 is provided at a lower portion of a base end of the accelerator pedal 3. A pressing shaft 4 extending in a lateral direction which is a lateral direction and orthogonal to the vehicle traveling direction is provided, and a screw 5 is formed at an extending portion of the pressing shaft 4.

Further, the screw 5 of the pressing shaft 4 is screwed into the holding member 6 which is fixed to the floor surface (not shown) of the automobile body, and the accelerator pedal 3
Is swingably supported, and the pressing shaft 4 is laterally moved forward and backward.

In addition, the brake lamp 2 is electrically connected to the brake lamp 2.
An operating rod 9 of a switch 8 connected via a control unit 7 for illuminating or blinking is provided in a related manner at a predetermined distance from one end of the pressing shaft 4 of the accelerator pedal 3.

In addition, the above-mentioned interval is an interval in which the operating rod 9 of the switch 8 is pressed to operate when the accelerator pedal 3 is released, and is an interval in which the accelerator pedal 3 is released when the accelerator pedal 3 is depressed.

Further, it has an appropriate mechanism (not shown) for returning to the upper swing position when the accelerator pedal 3 is released.

Next, another embodiment shown in FIG. 3 will be described. Fixing members 10 and 10a are provided on the floor surface side by side at predetermined intervals in a lateral direction orthogonal to the traveling direction of the vehicle. The outer cylinder 11, which is formed into a cylindrical shape across the space, is laid horizontally, and the outer cylinder is
An opening 12 is formed in the middle of 11.

Further, a cylindrical columnar cam having a predetermined cam groove 13 is formed as the pressing shaft 4, and the pressing shaft 4 is fitted in the outer cylinder 11 so as to be rotatable and movable in the lateral direction which is the axial direction. And cam groove
13 is located in the opening 12.

In addition, the support member 1 is provided on both sides of the lower base end of the accelerator pedal 3.
4, 14a are fixedly mounted, and the outer cylinder 11 is fitted to the supporting members 14, 14a to support the accelerator pedal 3 swingably, and a cam follower 15 fitted in the cam groove 13 of the pressing shaft 4 is provided. The pressing shaft 4 is laterally moved forward and backward by being fixedly mounted on the lower surface of the accelerator pedal 3.

In the figure, 16 is a straight guide groove, and 17 is a straight guide pin.

Next, the operation of the notice brake device according to the present invention will be described. First, when the pressing shaft 4 has a screw mechanism, when the accelerator pedal 3 is released, the accelerator pedal 3 returns to the upward swinging position, and Along with this, the pressing shaft 4 is interlocked, the rotational force is converted into a rectilinear force by the screw action of the screw 5 of the pressing shaft 4 and laterally moved in the direction of the switch 8, and the switch 8 is operated at one end of the pressing shaft 4. The rod 9 is pressed to operate the switch 8 to turn on or blink the brake lamp 2 via the control unit 7.

Next, in the case where the pressing shaft 4 has a cam mechanism, the accelerator pedal 3 is released to return the accelerator pedal 3 to the upper swing position, and the cam follower 15 is moved in the cam groove 13 of the pressing shaft 4 accordingly. By moving the pressing shaft 4, the cam force of the pressing shaft 4 converts the rotational force into a rectilinear movement force to move laterally in the direction of the switch 8, and at one end of the pressing shaft 4, the operating rod 9 of the switch 8 is moved.
Is pressed to operate the switch 8 to turn on or blink the brake lamp 2 via the control unit 7.

[Effect of device]

In short, according to the present invention, in the accelerator pedal which is swingable and returns to the upper swing position, it is orthogonal to the traveling direction of the vehicle through a screw or a cam mechanism that converts the rotational force due to the swing of the accelerator pedal 3 into a straight driving force. Since the pressing shaft 4 for controlling the forward / backward movement in the lateral direction is provided, the accelerator pedal 3 and the pressing shaft 4 are provided.
Are connected by a screw or cam mechanism,
Since the amount of swing of the accelerator pedal 3 and the amount of actuation of the pressing shaft 4 can be arbitrarily set, the amount of swing of the accelerator pedal 3 due to the vibration force during traveling can be absorbed. It is possible to eliminate malfunctions that occur in a device in which a switch is directly connected to a pedal.

Further, since the switch 8 is arranged at a position facing one end of the pressing shaft 4 at a predetermined interval, and the switch 8 is connected to the control unit 7 for lighting or blinking the brake lamp 2, the accelerator pedal 3 is released at the time of release. Then, the accelerator pedal 3 is returned to the upper swing position, and accordingly, the pressing shaft 4 is interlocked to perform forward / backward control, and the switch 8 is operated at one end of the pressing shaft 4 to operate the control unit 7. By turning on or blinking the brake lamp 2 by the driver, the driver of the succeeding car can recognize the braking of the preceding car in advance, and the female driver, the paper driver and the elderly driver do not cause any time delay. Since the following vehicle can be notified of braking in advance, it can contribute to the reduction of rear-end collisions.

Further, since the notice brake device according to the present invention has a simple structure, it can be easily installed in an existing automobile, and its practical effect is great.
