Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pedal structure for performing a brake operation and an accelerator operation of a vehicle such as an automobile.

[0002]

2. Description of the Related Art On the floor at the foot of the right leg of the driver's seat of a vehicle,
A brake pedal is arranged on the left side and an accelerator pedal is arranged on the right side. The driver switches the right foot to the left or right so as to depress the left brake pedal when performing a brake operation and depress the right accelerator pedal when performing an accelerator operation.

[0003]

However, when driving a vehicle, especially when driving in a city, it is necessary to frequently repeat the brake operation and the accelerator operation. Is also big. In addition, when a sudden brake is applied, a time lag for step change is added, so that there is a problem that the braking distance becomes longer. Accordingly, an object of the present invention is to provide a new pedal structure that solves such a conventional problem.

[0004]

According to a first aspect of the present invention, there is provided a pedal structure for a brake operation and an accelerator operation provided on a floor portion 2 of a vehicle. 3 and a tread portion 4 rotatable in the front-rear direction of the vehicle with the support member 3 as a fulcrum.
The brake operation is performed by rotating the front portion of the tread portion 4 so as to incline toward the floor, and the accelerator operation is performed by rotating the rear portion of the tread portion 4 so as to incline toward the floor. It is a pedal structure of the vehicle configured as described above.

In the operation pedal structure configured as described above, it is possible to switch between the brake operation and the accelerator operation only by inclining the right foot in the front-rear direction. (That is, the brake operation can be performed by pressing the toe side downward, and the accelerator operation can be performed by pressing the heel side downward.) Therefore, even if the brake operation and the accelerator operation are repeated frequently, foot fatigue Less degree. Furthermore, a person naturally applies a force to the toe side against danger, so that a quick braking operation can be performed when sudden braking is applied, so that the time lag is small and the braking distance is shortened accordingly.

The invention according to claim 2 is a preferred embodiment of the pedal structure according to claim 1, characterized in that a foot portion extending upward is provided at the front end of the tread portion. It is assumed that. By providing such a foot stop, it is possible to prevent unnecessary sliding of the right foot forward even when performing a sudden braking operation.

[0007]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view schematically showing one example of the pedal structure of the present invention. The pedal structure 1 includes a support member 3 provided on a floor 2 of a vehicle such as an automobile, and a tread plate portion 4 rotatable in the front-rear direction of the vehicle with the support member 3 as a fulcrum. At the front end of the tread portion 4, a foot portion 5 extending upward in an arc shape is integrally provided. In addition, this foot stop may be raised vertically. The support member 3 has a pair of parallel legs 3a and a shaft 3b bridged between them, and each leg 3a is fixed to the floor 2 by a fixing tool such as a bolt or a screw or by welding. .

The tread portion 4 includes a plate-shaped main body 4a and the main body 4a.
and a connecting portion 4b integrally provided at a middle portion of the bottom surface of FIG. The connecting portion 4b is provided with a bearing (not shown), and the shaft 3b is supported by the bearing. And the support member 3
The front side of the main body 4a (that is, the front side of the vehicle) is the brake pedal section 6 and the rear side is the accelerator pedal section 7 with the. A master cylinder 8 for a hydraulic brake is mounted on a frame 2 a located below the brake pedal 6, and an operation shaft 9 of the master cylinder 8 projects upward through the floor 2. A hole 9a is provided at the upper end of the operation shaft 9, and a stopper pin 9b is provided at the middle portion. Have been. The brake hydraulic pipe 11 extending from the master cylinder 8 is connected to a brake mechanism (not shown).

An operation shaft 12 for operating the throttle valve of the engine is arranged below the accelerator pedal section 7. Hole 12a at the upper end of operation shaft 12, stopper pin 1 at the middle
The operation shaft 12 is always extended upward by a compression spring 13 having one end hooked to the hole 12a, and is positioned by a stopper pin 12b. A wire 14 extending from the lower end of the operating shaft 12 via a guide roller 14a is connected to a throttle valve (not shown) for adjusting fuel to the engine. In addition, each operation axis 1
The distance between the shafts 2 and 9 and the shaft 3b of the support member 3 can be set by appropriately obtaining optimum conditions. Next, FIG.
Rollers 9c and 12c are rotatably arranged at the tips of the rollers 2 and 9, respectively, to improve operability and durability. Furthermore, another link mechanism (not shown) is interposed in the transmission mechanism between the accelerator pedal section 7 and the operation shaft 12 for operating the throttle valve.

Next, the operation of the pedal structure will be described with reference to FIG. 1. During driving of the vehicle, the driver places the right foot 15 on the tread plate portion 4 to perform a brake operation or an accelerator operation as shown in FIG. That is, when operating with a constant throttle valve opening, the heel 15a is pushed down to
Is tilted so that the rear side is downward as shown by the dashed line,
The operation shaft 12 for operating the throttle valve is pushed downward. As a result, the wire 14 connected to the lower end of the operating shaft 12 is pulled downward, whereby the throttle valve opens at a predetermined angle to feed fuel to the engine. Since the opening of the throttle valve is proportional to the angle of inclination on the tread portion 4, the accelerator amount can be adjusted by the amount of depression of the heel 15a. When the heel 15a and the toe 15b are in a horizontal state, the tread portion 4 is horizontal as shown by the solid line, and the pressing force on the operation shaft 12 is released. Then, the operation shaft 12 is raised by the action of the compression spring 13, the throttle valve is closed, and the fuel supply amount to the engine becomes the minimum value or stops.

Next, when the brake is operated, the toe 1
5b is depressed downward to incline the tread plate portion 4 so that the front side is downward as indicated by a dashed line, and the operating shaft 9 is depressed downward to increase the hydraulic pressure of the master cylinder 8. Since the increase in hydraulic pressure is proportional to the inclination angle of the tread portion 4, the amount of brake operation can be adjusted by the amount of depression of the toe. In the case of driving with slippery shoes, the right foot slides forward and is easy to move when sudden braking is applied, but the unnecessary foot portion 5 provided at the front end of the tread plate portion 4 as described above makes unnecessary movement. Slip is prevented.

[0012]

As described above, the pedal structure according to the first aspect of the present invention includes the support member provided on the floor and the tread portion which is rotatable in the longitudinal direction of the vehicle with the support member serving as a fulcrum. ,
The brake operation is performed by rotating the front portion of the tread portion so as to tilt downward, and the accelerator operation is performed by rotating the rear portion so that the rear portion tilts downward. Can be used to switch between brake operation and accelerator operation. Therefore, even if brake operation and accelerator operation are frequently repeated, the degree of foot fatigue is small,
Even when sudden braking is applied, quick braking can be performed, the time lag is small, and the braking distance is shortened accordingly. Further, the pedal structure according to claim 2 is characterized in that a foot portion extending upward is provided at a front end portion of the tread plate portion, so that even when a sudden braking operation is performed, the right foot cannot be moved forward. The necessary slippage can be prevented.
