BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle operation pedal device such as a brake pedal and an accelerator pedal, and more particularly to an improvement of an operation pedal device capable of moving the position of a pedal pad in the vehicle front-rear direction. Is.

2. Description of the Related Art A bracket fixed to a vehicle body is rotatably provided around a uniaxial center, and a pedal pad is depressed to rotate the pedestal from its original position to a uniaxial center so that a predetermined distance can be obtained. Vehicle operation pedal devices for pressing and pulling action members, such as brake pedals, accelerator pedals, and clutch pedals are widely known. One of such vehicle operation pedal devices is the pedal pad in the original position. It has been proposed that the position of can be moved in the front-back direction of the vehicle. For example, JP-A-63-4
9528 (conventional example 1), JP-A-2-39214 (conventional example 2), JP-B-62-5700 (conventional example 3), JP-B-62-22886 (conventional example 4),
The device disclosed in Japanese Utility Model Publication No. 52-44985 (Prior art example 5) is an example thereof. According to such an operation pedal device, the position of the pedal pad is optimized in accordance with the body shape and taste of the driver. Since it can be adjusted to various positions, driving operation becomes easy.

In the above-mentioned conventional examples 1 to 3, the pedal pad is moved in parallel along a pair of elongated holes, and in the conventional examples 1 and 2, the supporting portion and the action of the bracket which is the uniaxial center. By displacing the connecting portion of the member with the front-back movement of the pedal pad, the ratio of the distance from the uniaxial center to the pedal pad to the distance from the uniaxial center to the connecting portion of the action member (hereinafter referred to as the lever ratio) Is set to be substantially constant so that the required pedal operation force does not change even if the pedal pad is moved back and forth. In the conventional example 4, the push rod as the acting member is constituted by the screw shaft, and the operation pedal is changed by changing the connecting position of the operation pedal connected to the screw shaft via the nut member by the rotation of the screw shaft. The pedal pad is moved back and forth by rotating it about an axis, and the lever ratio is kept constant. In addition, in the conventional example 5, a rotary member that is rotatably disposed around a uniaxial center and to which an action member is coupled, and a relative rotatably position of the rotary member at a position different from the uniaxial center. A pedal pad provided on the operation pedal can be moved back and forth by changing the connection angle of the operation pedal with respect to the rotating member by a ratchet mechanism.

[0004]

However, in the conventional examples 1 and 2, the number of parts is large, the structure is complicated and large-scaled, and the assembly is troublesome and the cost is high. Further, in Conventional Example 1, since the center of rotation of the operation pedal, that is, the position of the uniaxial center changes, it is difficult to obtain structurally sufficient strength. Although the conventional example 3 has a simple structure, it is locked by fitting the notch and the projection, so that the front-back adjustment is stepwise and the pedal pad sways up and down during the adjustment, and the adjustment cannot be performed smoothly. At the same time, since the lever ratio changes with the movement of the pedal pad, the required stepping operation force changes. Further, in all of these conventional examples 1 to 3, since the pedal pad is moved in parallel along the elongated hole, when it is possible to adjust using a screw shaft or the like, the movement stroke of the pedal pad A drive device having the above length is required, and a comparatively large space in the front-rear direction is required, which is not preferable to arrange in a narrow space in front of the driver's seat.

On the other hand, in Conventional Example 4, the structure of the connecting portion between the push rod and the operation pedal is complicated, and the meshing of the gears that rotate the screw shaft during adjustment is unstable, which causes a problem in operability. Even if the lever ratio is constant, as shown in FIG. 8, the height of the connecting position with the push rod 122 changes as the operation pedal 120 rotates in the front-rear adjustment, and the operation pedal 120 and the push rod 122 are connected. Since the connection angle changes, for example, when the pedal pad 124 is moved from the vehicle front side to the vehicle rear side, as the movement locus of the connection position during the stepping operation changes from A to B,
As shown in FIG. 9, the characteristic of the operating force required for the stepping operation changes from A shown by the solid line to B shown by the broken line, which causes the driver to feel uncomfortable. Further, in the conventional example 5, since the operation pedal is rotated around an axis different from the one axis, the distance from the pedal pad to the one axis is changed with the rotation, and the lever ratio is changed. And the required stepping force changes.

The present invention has been made in view of the above circumstances. The object of the present invention is to provide a smooth and easy movement during forward / backward adjustments, a compact structure, and a sufficient structural strength. An object of the present invention is to provide an operation pedal device in which the lever ratio is constant and the pedaling force characteristic at the time of stepping operation hardly changes.

[0007]

In order to achieve such an object, a first aspect of the present invention is to provide a bracket fixed to a vehicle body so as to be rotatable about an axis, and a pedal pad is depressed. The operation pedal device is capable of moving the position of the pedal pad in the front-rear direction of the vehicle while pressing or pulling a predetermined acting member by being rotated from its original position around its one axis. And (a) an operation pedal which is attached to the bracket so as to be rotatable about the uniaxial center and which is provided with the pedal pad, and (b) rotatably around the uniaxial center and the operation. The bracket is disposed so as to be rotatable relative to the pedal, the action member is rotatably connected about an axis substantially parallel to one axis thereof, and abuts a stopper provided on the vehicle body. An adjusting rotary member whose original position is defined; and (c) a connecting angle that is provided across the adjusting rotary member and the operation pedal, and the adjusting rotary member and the operation pedal are connected at different connection angles. Front and rear adjustment means for positioning the pedal pad to change the position of the pedal pad.

[0008]

In the operation pedal device capable of adjusting the front-rear direction, the connecting angle between the adjusting rotation member and the operation pedal, both of which are provided so as to be rotatable about the uniaxial center, can be adjusted. The operation pedal is rotated about one axis with respect to the adjustment rotation member whose original position is regulated by the stopper by changing it by the front-back adjustment means arranged across two members. The longitudinal position of the pedal pad provided on the operation pedal is adjusted. In that case, since it is sufficient to relatively rotate the operation pedal with respect to the adjustment rotating member, the device can be configured simply and the pedal pad can be smoothly adjusted in the front-rear direction. Further, for example, if the front-rear adjusting means having a function of rotating the both relative to each other is configured in the vicinity of the uniaxial center, the pedal pad can be largely moved with a small adjustment allowance, and the front-rear adjusting means operates the operation pedal. Since it suffices to be able to rotate relative to the adjustment rotating member, it is not always necessary to dispose in the front-rear direction of the vehicle, and the disposition space in the front-rear direction can be reduced. Further, since the position of the uniaxial center, which is the center of rotation of the adjusting rotation member and the operation pedal, does not change, structurally high strength is obtained, and the lever ratio is constant regardless of the forward / backward adjustment and the action member and Since the connection position of is not changed, the required stepping force and the stepping force characteristic at the time of stepping operation are maintained substantially constant.

[0009]

A second aspect of the present invention is an operation pedal device according to the first aspect of the present invention, which is adjustable in the front-rear direction.
(D) The adjusting rotating member has a pair of side surface portions that are located at right angles to the uniaxial center and on both sides of the operation pedal, and (e) the front-rear adjusting means is configured to have the uniaxial center. A first elongated hole formed in the operation pedal so that the distance changes in the longitudinal direction, and a second elongated hole formed in each of the pair of side surface portions so as to intersect with the first elongated hole. A pin that is arranged to penetrate therethrough, and one of the adjusting rotation member and the operation pedal that is arranged to hold the pin in a position substantially parallel to the one axis and pierce the other member. And a moving means for moving along the elongated hole.

[0010]

That is, the first and second elongated holes respectively formed in the pair of side surface portions of the operation pedal and the adjusting rotary member, and the pin penetrating the first and second elongated holes, Two cam mechanisms are configured,
By moving the pin in either one of the elongated holes by the moving means, the intersecting position of the pair of elongated holes is changed, whereby the adjustment rotating member and the rotating member for adjustment capable of relative rotation about the one axis are operated. The connection angle with the pedal is changed. Here, since the forming directions of the first oblong hole and the second oblong hole can be set relatively freely, there is a high degree of freedom in setting the moving direction of the pin, that is, the arranging direction and the arranging position of the moving means.
It becomes easy to design the device so that it fits in the narrow space in front of the driver's seat. In addition, since the bidirectional relative rotation around both uniaxial centers is blocked, compared with the case where only the relative rotation in the stepping direction of the operation pedal is blocked by using the contact bolt or the ratchet mechanism, The rattling of the operation pedal is prevented.

[0011]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a partially cutaway front view showing an example in which the present invention is applied to a vehicle brake pedal device 10 as an operation pedal device. The brake pedal device 10 includes a bracket 1 fixed to a vehicle body 12.
4 and the bracket 14
The operation pedal 18 is rotatably arranged around the axis O ₁ of the support shaft 16 via the support shaft 16 and the operation pedal 18 in a fashion straddling the base end portion of the operation pedal 18. An adjusting rotation member 20 is provided so as to be rotatable relative to the operation pedal 18. A pedal pad 22 is provided at the tip extending substantially downward of the operation pedal 18, and when the pedal pad 22 is depressed, the operation pedal 18 is rotated clockwise in FIG. Figure 2 is a sectional view taken along line II-II in FIG. 1, as seen from this figure, the support shaft 16, the nut bolts mainly, the sleeve is constituted by a bush, whose axis O ₁ single It is attached to the bracket 14 in such a posture that it corresponds to the center and its axis O ₁ is substantially parallel to the width direction of the vehicle.

The adjusting rotary member 20 is composed of a bent plate material, and is a pair of side surface portions 2 which are perpendicular to the upper back portion 24 and the support shaft 16 and are located on both sides of the operation pedal 18.
6, 26 has a U-shaped cross section, and the rod 28 of the brake booster 30 is parallel to the axis O ₁ at the end opposite to the back 24, that is, at the lower end in FIG. It is rotatably connected around the pin 34. By urging the rod 28 by the brake booster 30 in the protruding direction, that is, in the right direction in FIG. 1,
A moment in the counterclockwise direction of the axis O ₁ is always applied to the adjusting rotary member 20. Figure 1 of the back 24
The right side portion of the bracket is brought into contact with the stopper screw 36 provided on the bracket 14, and this contact defines the turning end in the counterclockwise direction in FIG. 1, that is, the original position. The stopper screw 36 corresponds to a stopper.

Since the connecting angle between the adjusting rotary member 20 and the operation pedal 18 is always positioned by the front-rear adjusting means described later, the pedal pad 22 is depressed to rotate the adjusting pedal together with the operation pedal 18. By rotating the member 20 from the original position, the rod 28 is pressed and the push rod of the master cylinder (not shown) is pushed in to generate the brake hydraulic pressure. In this embodiment, the rod 28 of the brake booster 30 corresponds to the acting member. Further, although the brake pedal device 10 can be returned to the original position by the rod 28, a return spring is arranged between the bracket 14 and the adjusting rotary member 20 or the operation pedal 18 as required. You can also

The operation pedal 18 has an axis O of the support shaft 16.
The first elongated hole 3 so that the distance to ₁ changes in the length direction, specifically, the length direction substantially intersects the axis O _1.
8 is pierced to penetrate in the plate thickness direction parallel to the axis O ₁ , while the pair of side surface portions 26, 26 of the adjusting rotation member 20 is provided.
The first elongated hole 38 when viewed from a direction parallel to the axis O _1.
The second elongated holes 40, so that they intersect at a predetermined angle with
40 penetrates in the plate thickness direction and is respectively drilled. Then, as can be seen from FIG. 3, which is a sectional view taken along line III-III in FIG. 1, a pin 42 that penetrates both of the elongated holes 38 and 40 at the intersecting position connects the operation pedal 18 and the adjusting rotating member 20. It is inserted through the insertion hole 46 of the clevis 44 arranged in the middle and is held in a posture substantially parallel to the axis O ₁ , so that the relative position between the operation pedal 18 and the adjusting rotating member 20 is maintained. Be related.

That is, the first elongated hole 38, the second elongated hole 40 and the pin 42 constitute one cam mechanism, and one of the elongated holes corresponding to the position of the pin 42 corresponds to the other elongated hole. Since the intersecting position is defined, the connecting angle between the operation pedal 18 and the adjusting rotating member 20 can be changed by moving and positioning the pin 42 in one of the elongated holes. In FIG. 1, the pin 42 has the second long hole 4
0 is located at the lower moving end of the first elongated hole 38 and is located at the outer peripheral moving end of the first elongated hole 38 with respect to the axial center O ₁ . The pedal pad 22 is positioned at the turning end that is turned to the rightmost relative to the moving member 20, and the pedal pad 22 is positioned closest to the front of the vehicle.

In FIG. 3, the clevis 44 has an upper back portion 48 and a pair of side surface portions 50, 50 on both sides similarly to the adjusting rotation member 20, and has a U-shaped vertical cross section. The insertion holes 46 are provided at the tip ends of the side surfaces 50, and the nut member 52 is fixedly provided inside the back portion 48. On the other hand, the adjusting rotation member 2
The 0 back portion 24 has a portion that is perpendicular to the longitudinal direction of the second elongated hole 40, and an electric motor 54 is attached to the outside of that portion. A screw shaft 56, which is an output shaft of the electric motor 54, projects into the back portion 24, penetrates the back portion 48 of the clevis 44, and is screwed into the nut member 52. In this embodiment, the clevis 44, the electric motor 54 and the like constitute a moving means 58 for moving the pin 42. As described above, the nut member 52 is screwed into the screw shaft 56, and the insertion hole 46 is guided to the second elongated hole 40 through the pin 42, so that the clevis 44 has a posture substantially parallel to the second elongated hole 40. Maintained at.

When the screw shaft 56 of the electric motor 54 is normally or reversely rotated by operating a switch (not shown) provided near the driver's seat, the clevis 44 is linearly moved in the axial direction of the screw shaft 56 according to the rotating direction. Then, the pin 42 is moved along the second elongated hole 40 (in the substantially vertical direction in FIG. 1) while holding the pin 42 in a posture parallel to the axis O ₁ . Since the second oblong hole 40 intersects the first oblong hole 38, when the pin 42 moves up and down in the second oblong hole 40, the axial center O with respect to the second oblong hole 40.
The first elongated hole 38 capable relative rotation about ₁ is moved so that mutual intersection position changes, the operating pedal 18 relative times with respect to the adjustment pivot member 20 which is held in the original position Be moved. Therefore, when the clevis 44 is moved closer to the electric motor 54 side from the state of FIG. 1, the operation pedal 18 is rotated counterclockwise in FIG. 1, and the position of the pedal pad 22 is moved to the vehicle rear side. . Then, in the state of FIG. 4 in which the pin 42 reaches the upper moving end on the opposite side of the lower moving end of the second elongated hole 40, the pedal pad 22 is positioned closest to the rear of the vehicle. Therefore, by moving the pin 42 by the moving means 58 and positioning the adjusting rotary member 20 and the operation pedal 18 at different connection angles, the position of the pedal pad 22 is changed to the position shown in FIG.
Can be arbitrarily changed within the range between the position of and the position of FIG. In the present embodiment, the pin 42 penetrating the elongated holes 38 and 40 provided in the operation pedal 18 and the adjusting turning member 20 respectively, and the moving means 58 provided in the adjusting turning member 20 are used to move back and forth. An adjusting means is configured.

When the pedal pad 22 is stepped on, a shearing force and a bending force are applied to the pin 42 in correspondence with the operating tread force, but the clevis 44 and the adjusting rotating member 2 are used.
Since 0 is compactly configured in the vehicle width direction and the length dimension required for penetration is relatively short, the pin 42 is not deformed by the stepping operation. Also, regarding the clevis 44 and the screw shaft 56, since only the pulling force acts by the pin 42 that tries to move along the second elongated hole 40 during the stepping operation, it is lightweight and compact while having sufficient strength. Composed.

As described above, in the brake pedal device 10 of the present embodiment, by operating the switch provided in the driver's seat to move the pin 42 by the moving means 58, both the axes O _{1 of the} support shaft 16 are rotated. By changing the connection angle between the operation pedal 18 rotatably arranged and the adjustment rotation member 20, the operation pedal is adjusted with respect to the adjustment rotation member 20 whose original position is defined by the stopper screw 36. 18 is rotated about the axis O ₁ , and the position of the pedal pad 22 provided on the operation pedal 18 in the front-rear direction is adjusted. In that case, since the operation pedal 18 may be relatively rotated with respect to the adjustment rotation member 20, the device is simply configured and the pedal pad 22 can be smoothly adjusted in the front-rear direction. Further, the first elongated hole 38, the second elongated hole 40, and the pin 42 are formed in the vicinity of the axis O ₁ ,
The pedal pad 22 is largely moved with a small adjustment allowance, and the moving means 58 is arranged in the substantially vertical direction of the vehicle rather than in the front-back direction, so that the space for arrangement in the front-back direction is small. Further, the adjusting rotation member 20 and the operation pedal 1
Since the position of the axis O ₁ that is the center of rotation of 8 does not change,
The rotation is smooth and structurally high strength is obtained, and the lever ratio is constant and the rod 28
Since the connection position with and does not change, the required stepping force and the pedaling force characteristic at the time of stepping operation are maintained substantially constant.

Further, in this embodiment, the first elongated hole 38 and the second elongated hole 38
A cam mechanism is formed by the long holes 40 and the pins 42, and the pins 42 are moved in the second long holes 40 by the moving means 58 including the clevis 44, the electric motor 54, etc. Changed,
As a result, the connecting angle between the operation pedal 18 and the adjusting rotary member 20 that can be relatively rotated about the axis O ₁ is changed, but the forming directions of the elongated holes 38 and 40 can be set relatively freely. Since it is possible and the degree of freedom in setting the movement direction of the pin 42, that is, the arrangement direction and the arrangement position of the moving means 58 is high, it is easy to design the device so as to fit in the narrow arrangement space in front of the driver's seat. In addition, the operation pedal 18
Since the bidirectional relative rotation around the axis O _{1 of} both of the adjustment rotation member 20 and the adjustment rotation member 20 is prevented, only the relative rotation in the stepping direction of the operation pedal 18 is performed by using the contact bolt or the ratchet mechanism. Rattling of the operation pedal 18 is prevented as compared with the case of blocking.
