TECHNICAL FIELD OF THE INVENTION
The present invention relates to an accelerator pedal device for an automobile.
[0002]
[Prior art]
A commonly used accelerator pedal includes an accelerator lever rotatably supported by a bracket fixed to a vehicle body and a pedal fixed to a lower end of the accelerator lever. And the like via a control cable.
[0003]
Unlike the brake pedal and the clutch pedal, the accelerator pedal needs to be finely adjusted in the amount of depression, and therefore, the pedal is often operated with the heel attached to a certain place on the floor. In this case, if the position of the heel is close to the seat side, there is a feeling of cramping. Therefore, it is easier to operate the heel as close as possible to the front of the vehicle, that is, the accelerator pedal.
[0004]
[Problems to be solved by the invention]
However, when the position of the heel is brought closer to the accelerator pedal in this way, the back surface of the foot comes into contact with the lower edge of the pedal in the initial stage of stepping on the pedal.
In order to improve the legging property, the mounting angle of the pedal with respect to the accelerator lever may be increased. However, when the pedal is depressed, the lower end of the pedal easily comes into contact with the floor, and a sufficient stroke amount cannot be secured.
[0005]
By the way, an accelerator pedal which pivotally supports a pedal at a lower end portion of the accelerator lever by a predetermined angle so as to be swingable, and provides a spring between the accelerator lever and the pedal for urging the lower end portion of the pedal upward with respect to the accelerator lever. An apparatus has been proposed (JP-A-8-2282). The spring has a function as an anti-vibration member that prevents the vibration of the engine or the like from being transmitted to the driver's foot via the pedal.
[0006]
In this case, the pedal can swing with respect to the accelerator lever at the initial stage of depressing the pedal, so even if the heel position is changed to a position close to the accelerator pedal, the sole of the foot can be fitted to the pedal, There is an advantage that the property can be improved. However, since the accelerator lever extends downward by the same length as the pedal, when the pedal is depressed, the lower end of the pedal first comes into contact with the accelerator lever, turns downward in that state, and the lower end of the accelerator lever. Hits the floor and becomes the limit of stepping on the floor. That is, after the pedal swings with respect to the accelerator lever in the initial stage of the depression, the pedal and the accelerator lever merely rotate integrally, and a sufficient stroke amount may not be secured.
[0007]
Accordingly, an object of the present invention is to provide an accelerator pedal device for an automobile that can improve the footing at the initial stage of depression and secure a sufficient pedal stroke while moving the position of the heel forward as much as possible to eliminate the cramped feeling. Is to do.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides an accelerator lever rotatably supported by a bracket fixed to a vehicle body and having an upper end connected to a control cable, and an accelerator lever swinging at a predetermined angle to a lower end of the accelerator lever. and axially supported by the pedal can be provided between the accelerator lever and the pedal, and a spring for upwardly urging the swing a lower end of the pedal, the lower end portion of the pedal below the lower end of the accelerator lever The angle of the pedal is set so that the back of the shoe contacts the lower end of the pedal before the driver puts the heel of the shoe on the floor and depresses the pedal, and the driver depresses the pedal. When the pedal is set spring force of the spring so that the rear surface of the shoes with relatively swing with respect to the accelerator lever is in contact with the surface of the pedal, further write down the above pedal I When only the lower end portion of the pedal to provide an accelerator pedal device of an automobile, wherein a stopper portion abutting is provided on the floor.
[0009]
When the pedal is depressed with the heel position close to the accelerator pedal, the sole of the foot contacts the lower end of the pedal in the initial stage of depression, but the pedal swings in the upright direction against the accelerator lever against the spring. Therefore, the sole of the foot can be fitted to the pedal, and the feeling is improved. When the pedal is further depressed, the lower end of the pedal comes into contact with the stopper on the floor, but since there is a gap between the floor and the accelerator lever, rotate the accelerator lever further forward to the swing limit position with the pedal. And a sufficient pedal stroke can be secured.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
1 to 3 show an example of an accelerator pedal device according to the present invention.
The accelerator pedal device includes an accelerator lever 1 made of a metal rod. An intermediate portion of the accelerator lever 1 is rotatably supported by a shaft 3 of a bracket 2 fixed to a dash panel 9, and a lower end of the accelerator lever 1 is directed upward by a torsion spring 4 inserted through the shaft 3. Is urged to rotate. 2, a notch groove 5 is formed at the upper end of the accelerator lever 1, and one end of a control cable 6 connected to a throttle valve of an engine or the like is connected to the groove 5. Reference numeral 8 denotes a stopper rubber for fixing the return position fixed to the dash panel 9.
[0011]
A pedal 10 integrally formed of resin is swingably attached to the lower end of the accelerator lever 1. That is, a pair of bearings 11 project from the rear surface of the central portion of the pedal 10, and a shaft 12 supported by these bearings 11 is rotatably inserted into the lower end of the accelerator lever 1. A spring 13 formed of a torsion spring is inserted through the shaft 11. One end of the spring 13 is locked on the lower surface side of the accelerator lever 1, and the other end is locked on the back surface of the pedal 10. Therefore, the lower end of the pedal 10 is urged to swing upward. A penetrating portion 14 having a long hole 14a protrudes from an upper back surface of the pedal 10, and a lower end portion of the accelerator lever 1 is inserted through the long hole 14a. Therefore, the pedal 10 can swing up and down with respect to the accelerator lever 1 by the length of the elongated hole 14a. Further, a contact portion 15 is protruded from the lower rear surface of the pedal 10, and the contact portion 15 can contact a stopper portion 22 of a floor 20 described later.
[0012]
The floor 20 is formed continuously with the dash panel 9, and a carpet 21 is laid on the indoor side. When the pedal 10 is depressed, a stopper portion 22 that comes into contact with the contact portion 15 of the pedal 10 protrudes from the floor 20, and the stopper portion 22 is also covered with the carpet 21. An escape portion 23 is formed above the stopper portion 22 of the floor 20 so as to be recessed toward the front of the vehicle so as not to interfere with the lower end portion of the accelerator lever 1.
[0013]
Next, the operation of the accelerator pedal device having the above configuration will be described with reference to FIGS.
FIG. 4 shows a state before stepping on. The back surface of the shoe S is placed on the pedal 10 with the heel P attached to the carpet 21 on the floor 20. At this time, the back surface of the shoe S is in contact with the lower end of the pedal 10.
In this state, the back surface of the shoe S does not fit the surface of the pedal 10 so that the foot is not easily attached. However, when the pedal 10 is slightly depressed, the pedal 10 opposes the spring 13 as shown in FIG. And the back surface of the shoe S fits the pedal 10. Therefore, even if the position of the heel P is moved forward, the back of the shoe S can be fitted to the pedal 10, and the feeling of cramping can be eliminated and the feeling can be improved.
When the pedal 10 is further depressed, the pedal 10 and the accelerator lever 1 rotate integrally, and the control valve 6 connected to the upper end of the accelerator lever 1 is pulled to operate the throttle valve. Eventually, as shown in FIG. 6, the contact portion 15 at the lower end of the pedal 10 contacts the stopper portion (carpet) 22 of the floor 20.
When the upper part of the pedal 10 is depressed from this state, the pedal 10 swings relatively to the accelerator lever 1 as shown in FIG. 7 and the accelerator lever 1 further pivots forward. Therefore, a sufficient stroke amount can be secured.
[0014]
In the above description, the case where the pedal 10 swings clockwise with respect to the accelerator lever 1 (see FIG. 7) after the contact portion 15 of the pedal 10 hits the stopper portion 22 of the floor 20 (see FIG. 6). However, it is considered that there are more cases where the state of FIG. 7 is actually reached without going through the state of FIG. That is, when the pedal 10 is depressed from the state of FIG. 5, the pedal 10 swings clockwise in FIG. 5 as the pedal is depressed, and before the contact portion 15 of the pedal 10 hits the stopper portion 22, the pedal 10 is This is because the state where the pedal 10 is swung clockwise to the swing limit position, and thereafter the contact portion 15 of the pedal 10 contacts the stopper portion 22 in many cases. In this case, the position of the pedal 10 at which the back surface of the shoe S contacts is substantially fixed, and the distance from the rotation fulcrum 3 of the accelerator lever 1 to the point of application of the pedal 10 is substantially constant, so that pedal operability is improved. There is an advantage of doing so.
[0015]
The accelerator pedal device of the present invention is not limited to the accelerator lever 1 and the pedal 10 having the shapes as in the above embodiment. In the above embodiment, the insertion portion 14 having the elongated hole 14 a is formed on the upper back surface of the pedal 10 in order to regulate the swing angle of the pedal 10 with respect to the accelerator lever 1. The swing angle may be regulated by extending the lower end of the pedal 10 to an extent that does not exceed the lower end and bringing the lower surface of the lower end of the pedal 10 into contact with the lower end of the accelerator lever 1. However, it is necessary to devise the lower end of the accelerator lever 1 so that the pedal 10 does not come into contact with the floor before the pedal 10 comes into contact with the stopper 22 of the floor 20.
[0016]
【The invention's effect】
As is apparent from the above description, according to the present invention, the pedal is pivotally supported at the lower end of the accelerator lever by a predetermined angle so as to be swingable, and the lower end of the pedal is pivoted upward with respect to the accelerator lever by a spring. Because of the urge, even when the heel is positioned in front of the vehicle, the pedal swings in the rising direction at the initial stage of depression, and the sole of the foot can be fitted to the pedal. For this reason, the feeling of cramping can be eliminated, and the feeling in the initial stage of the stepping can be improved.
In addition, the lower end of the pedal extends downward from the lower end of the accelerator lever, and a stopper is provided on the floor where only the lower end of the pedal comes into contact when the pedal is depressed. Since there is a gap between the floor and the accelerator lever even when it is in contact with the stopper, the accelerator lever can be turned further forward to the swing limit position with the pedal, ensuring a sufficient pedal stroke. it can.
