Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to pedals used in various vehicles such as automobiles, construction machines, agricultural machines, electric vehicles and solar cars, and more particularly to a breakthrough development of brake pedals.

[0002]

2. Description of the Related Art Generally, in a conventional pedal mechanism, for example, an automobile, a brake pedal, an accelerator pedal, and a clutch pedal are arranged in parallel. And
The brake pedal is formed so that its depression stroke is much longer than that of the accelerator pedal. Therefore, the pedal operation requires a large movement of the entire leg with the crotch joint as a fulcrum, and the U-shaped footwork must be performed while spatially moving the heel position of the operating foot.

[0003]

By the way, in the above-mentioned conventional pedal mechanism, since the motion of pedal operation is inevitably a large U-shape of the entire leg, when a quick and quick operation is required. Trouble was easy to occur. That is, since the heel position of the operating foot during driving is not fixed depending on each driver's individuality, accidents such as pedal missteps or step delays are likely to occur during a critical emergency. In particular, it has been reported that such accidents often occur in automatic vehicles, because the operation rhythm is inherently difficult to obtain due to one-foot operation. Especially, when I was in a clutch car and changed to an automatic car, I had many accidents. Furthermore,
Once the car started to run out of control, it became more difficult to release the foot from the accelerator pedal and step on the brake pedal, as the foot stiffened from fear. On the other hand, since there is no support point for the foot, the driver's posture balance is maintained by the arm with the handle, and the grip strength of the handle increases, which causes a problem in dealing with an emergency.

The object of the present invention was made in view of the above-mentioned drawbacks, and it is not necessary to change the foot between the pedals.
The pedal change time is set to almost zero and the accelerator pedal is pressed by pressing the brake pedal once runaway begins.
Pedal mechanism that releases the pressing of the material, and the foot is rigid
It is an object of the present invention to provide a pedal mechanism capable of forcibly guiding the foot from the accelerator operation to the brake operation by the action of the guide member (derivative) even if the vehicle falls into a state .

[0006]

As described above, according to the pedal mechanism of the present invention, the brake pedal is rotatably supported by the joint portion in the left-right direction.
Being held and the brake pedal tread is not pressed
Since the accelerator operation member is arranged on the turning trajectory in
Brake operation is possible by pressing the rake pedal
At the same time, the pressing of the accelerator member is released and the brake pedal
Rotate it around the joint without pressing the
If you press the lever operation member, you can operate only the accelerator.
It Therefore, both the brake operation and the accelerator operation can be performed using the brake pedal. Therefore, the brake operation and the accelerator operation can be performed swiftly, and it is possible to easily perform a driving that requires skill such as starting and stopping on a slope and starting and moving backward. Further, when the guide member is provided, the curved surface portion of the guide member can forcibly guide the brake pedal to the initial position.

An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 is a plan view of a pedal mechanism according to an embodiment of the present invention, and FIG. 2 is a partially cutaway side view of the pedal mechanism according to an embodiment of the present invention. Here, the pedal mechanism includes a brake pedal tread plate 10, a first support rod 11 for supporting the brake pedal tread plate 10, a joint portion 12 for rotatably supporting the first support rod 11 by a predetermined angle, and this joint. Part 1
The second support rod 13 that supports the second support rod 13 and the first and second support rods that support the joint portion are engaged with each other to elastically and linearly hold the first support rod and the second support rod. Coil spring 1
4 and the accelerator operating member 15 is arranged on the rotation path of the brake pedal step plate 10. Here, the brake pedal step plate 10 has flanges 10a formed on both sides and has a substantially U-shaped cross section. Further, a spherical pressing portion 10 having a radius R is formed on one end of the lower surface of the brake pedal step plate 10.
b is formed. One end of the first support rod 11 is fixed to the bottom of the brake pedal step plate 10, and the other end thereof is connected to the joint 12. The joint 12 has a pin 16
And semicircular protrusions 12a, 12b and coil spring 1
4, the retaining pin 17 and the like. The left and right semi-circular protrusions 12a and 12b are respectively combined to form a pin 16
Is pin-joined so as to rotate by the notch angle θ of the collar portion. The winding portion of the coil spring 14 is wound around the large-diameter portion 16 a of the pin 16, and the arm portion 14 a extending from the winding portion is connected to the first supporting rod 11 and the second supporting rod 13. Each holds the lower end. Therefore, the brake pedal step plate 10 is rotated by the angle θ together with the first support rod 11 and is elastically held by the coil spring 14 so as to return to the original position. Also, coil spring 1
The fourth arm 14a has a first support rod 11 and a second support rod 1.
Since the lower end of 3 is held, the brake pedal step plate 1
The 0 is prevented from bending downward. Since the retaining pin 17 is inserted in the lower end of the pin 16, the pin does not come out.

The accelerator operating member 15 is located beside the brake pedal step plate 10 on a concentric circle centered on the pin 16. Here, the accelerator operation member 15 is connected to a carburetor or the like of an engine (not shown). A guide member (derivative) 18 is arranged below the accelerator operating member 15. The guide member (derivative) 18 has a vertical surface 18a that is substantially the same as the side surface of the pressing portion 10b of the brake pedal step plate 10.
And a curved surface portion 18b. As shown in FIG. 4, the radius of curvature R of the pressing portion 10b is determined by the accelerator operating member 15
Is larger than the receding distance A from the vertical surface 18a. Therefore, even if the pressing portion 10b of the brake pedal step plate comes into contact with the guide member (derivative) 18, the guide member 18 is smoothly guided in the vertical direction, and the brake operation becomes possible.

Next, the operation of the pedal mechanism constructed as above will be described. First, when the brake operation is performed, the brake pedal step plate 10 may be depressed like a normal brake pedal. Treading pressure via the brake pedal step plate 10 drives a hydraulic cylinder (not shown) through the first support rod 11 and the second support rod 13. Further, when the brake pedal is stepped on, the pressing portion 10b is separated from the vertical surface 18a by m (FIG. 5), so that friction is small. Even if an accelerator operation is attempted at this time, the accelerator cannot be operated because it abuts the vertical surface 18a, which is safe. When performing the accelerator operation, the depression of the brake pedal step plate 10 is stopped, and the brake pedal step plate 10 is moved in the direction of arrow R as shown in FIG. To do this, keep the heel of your right foot on the floor and rotate it to the right. At this time, the brake pedal step plate 10, the first
The supporting rod 11 rotates around the pin 16 against the coil spring 14. Further, when the foot is released, the brake pedal step plate 10 returns to the original position by the biasing force of the coil spring 14. The rotation of the brake pedal tread 10
When stopped, the horizontal distance from the accelerator operating member 15
Are separated by (l + m) (see FIG. 5).

Further, according to the pedal mechanism of the present invention, when the brake is operated during the accelerator operation, the brake pedal depressed is depressed.
The curved pressing portion 10b on the right side of the brake pedal tread 10 is
Guided by curved surface 18b of guide member (derivative) 18, left
Is guided in the direction . Therefore, if your foot gets stuck due to fear when the car is running out of control, use the foot
Even if the dull is depressed, the brake pedal is guided to the original position by the action of the curved surface portion 18b of the guide member (derivative) 18 and the braking operation is performed (FIG. 6). At this time, the brake pedal step plate 10 is placed along the curved surface portion 18b of the guide member 18.
It descends while making contact . This makes it possible to achieve safety and agility. In addition, if you feel sleepy while driving, the foot that pressed the accelerator is coil spring 1
The vehicle is automatically stopped and safe because it returns to its original position due to the biasing force of 4 . The heel may be left on the floor, or in an emergency, keep the heel off the floor without concern.
You may step on, so-called free footwork.

In the above embodiments, the case of application to an automobile has been described, but the present invention is not limited to this, and other vehicles such as construction machinery and agricultural machinery may be used. The present invention is not limited to the above embodiments, and various design changes can be made based on the technical idea of the present invention.

[0012]

As described in detail above, according to the pedal mechanism of the present invention, the operability is improved and it is possible to contribute to the safe driving of the automobile. In other words, when acceleration and braking operations are performed using the conventional two pedals, an accelerator and a brake, it takes time to change the pedal, and the time from when the driver feels danger until the braking operation starts There will be a delay. On the other hand, according to the pedal mechanism of the present invention, both acceleration operation and braking operation can be performed with one pedal operation. Therefore, the time delay for the step change operation can be made substantially zero, and the safety can be significantly improved. As a result, even a beginner, an elderly person, and an inexperienced person can drive safely. Further, since the flanges are provided on both sides of the brake pedal tread, the foot does not slip sideways from the tread. That is, even when the accelerator pedal is being pressed, if the braking operation is performed as it is, the braking operation can be performed by the guiding function of the curved surface portion of the guide member.
