DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a pedal displacement control structure for a vehicle.

[0002]

2. Description of the Related Art Conventionally, various arrangements have been devised as countermeasures when an external force exceeding a predetermined value acts on a front portion of a vehicle. As an example of this kind of countermeasure, there is a configuration disclosed in Japanese Utility Model Laid-Open No. 1-73664.

[0003] Briefly, as shown in FIG.
In the configuration disclosed in this publication, the steering column 402 covering the steering shaft 400 is
04 and a pair of side plate members 406, a tilt bracket 408, and a shaft 41 penetrating between these side plate members 406 and supporting a lower edge of the steering column 402
0 supports the vehicle.

Further, the tilt bracket 408 described above is used.
A knee protector 412 having a substantially circular arc shape and capable of being elastically deformed is provided below. The knee protector 412 is elastically supported on the lower edge side of the steering column 402 via an elastically deformable stay 414.

According to the above structure, when an external force equal to or more than a predetermined value acts on the front portion of the vehicle, the occupant attempts to inertia move toward the front of the vehicle, and accordingly, the legs of the occupant are bent in the same direction with the knee as a starting point. Try to inertia move to. Therefore, if the knee protector 412 is not provided, the occupant's knee may contact the tilt bracket 408. However, as described above, the tilt bracket 40
If knee protector 412 is arranged below 8, knees of the occupant will only contact knee protector 412.

The configuration of disposing the knee protector 412 is considered to be a significant measure as a countermeasure when an external force equal to or more than a predetermined value acts on the front portion of the vehicle, but as a countermeasure in relation to the occupant's legs. It is also possible to approach from a different viewpoint, and it is important from the viewpoint of multiple protection that the countermeasures in relation to the occupant's legs be multifaceted.

As a result of repeated experiments conceived from such a viewpoint, the inventor of the present invention focused on the deformation and displacement behavior of the body panel and the like when an external force of a predetermined value or more acts on the front portion of the vehicle, and focused on the brake pedal and the like. It has been concluded that controlling the displacement of the vehicle pedal is also a very effective measure.

SUMMARY OF THE INVENTION In view of the above findings, it is an object of the present invention to provide a vehicle pedal displacement control structure which can control displacement of a tread surface of a vehicle pedal when an external force of a predetermined value or more acts on a front portion of the vehicle. is there.

[0009]

According to a first aspect of the present invention, there is provided a vehicle pedal displacement control structure which is displaced substantially toward the rear of the vehicle when an external force of a predetermined value or more acts on the front of the vehicle. A first pedal bracket fixed to the vehicle body-side constituent member, and a suspension type vehicle pedal having a tread surface to which a passenger's treading force is applied at a lower end portion are swingably supported. First at a position substantially forward of the vehicle from the center of oscillation

The second pedal bracket is provided on a second vehicle body side component member that is relatively higher than the first vehicle body side member, and a relative displacement occurs between the first vehicle body side component member and the second vehicle body side component member. And a displacement control means for displacing substantially downward of the vehicle.

According to a second aspect of the present invention, in the vehicle pedal displacement control structure according to the first aspect, the displacement control means slides a rear end side of the second pedal bracket. And a guide member for displacing the side substantially downward of the vehicle.

According to the first aspect of the present invention, when an external force equal to or greater than a predetermined value acts on the front portion of the vehicle, the first vehicle body side component is displaced substantially toward the rear side of the vehicle. For this reason, the first pedal bracket fixed to the first vehicle body-side component member and the second pedal bracket swingably supported by the first pedal bracket are also displaced substantially toward the vehicle rear side.

On the other hand, the second vehicle body side component, which is disposed substantially rearward of the vehicle body with respect to the first vehicle body side component, has a substantially rigidity in the vehicle front-rear direction that is higher than that of the first vehicle body side component. Since it is relatively high, it is hardly displaced substantially toward the rear side of the vehicle. For this reason, relative displacement occurs between the first vehicle body side component member and the second vehicle body side component member, and the rear end side of the second pedal bracket is substantially moved by the displacement control means provided on the second vehicle body side component member. The vehicle is displaced downward. Accordingly, the vehicle pedal pivotally supported by the second pedal bracket is also displaced in the same direction. As a result, according to the present invention, when an external force equal to or greater than a predetermined value acts on the front portion of the vehicle,
The tread surface of the vehicle pedal is rotationally displaced substantially forward of the vehicle.

According to the second aspect of the present invention, the displacement control means includes a guide member for displacing the rear end side of the second pedal bracket substantially downward while sliding the rear end side thereof. Therefore, the amount and direction of displacement of the rear end side of the second pedal bracket can be easily controlled by adjusting the shape and the like of the guide means.

Pedal support portion 68 formed by appropriately bending a narrow plate material
And a pedal pad 70 provided at a lower end portion of the pedal support portion 68 and serving as a “tread surface” to which the occupant's treading force is applied,
It is comprised including. A push rod (operating rod) 72 protruding from the brake booster 20 and penetrating through the dash panel 16 (in a broad sense, grasped as a pedaling force transmitting means) is provided at an intermediate portion of the pedal support portion 68.
Are connected to each other. Specifically, a substantially U-shaped clevis 74 in a plan view is provided at the tip of the push rod 72.
Is attached. Inside the clevis 74, a pedal support portion 68 is disposed in an inserted state, and both sides of the clevis 74 and the pedal support portion 68 are connected to the clevis pin 76.
The push rod 72 and the pedal support 68 are relatively rotatably connected to each other by locking a split pin or the like at the penetrating end and preventing the push rod 72 from being pulled out.

A return spring (not shown) is locked to the pedal support 68 or the clevis pin 76 of the brake pedal 10, and the return spring always urges the brake pedal 10 in a direction to return to the initial position. .

As shown in FIG. 5, the pedal support 68
A through hole 78 is formed at the upper end of the. A cylindrical pedal boss 80 is press-fitted into the through hole 78,
Further, a cylindrical collar 82 is press-fitted into the pedal boss 80. A ring-shaped plate 84 is interposed between both ends of the collar 82 in the axial direction and the side plate portion 62 of the second pedal bracket 30. Further, an intermediate portion 30C of the second pedal bracket 30 (that is, an intermediate portion in the longitudinal direction of the side plate portion 62) includes:
A bolt insertion hole 86 is formed at a position coaxial with the collar 82. The position of the bottom of the notch 58 formed in the side plate portion 34 of the first pedal bracket 28 is set so that the bottom and the bolt insertion hole 86 are coaxially overlapped (FIG. 4). reference).

A mounting bolt 88 is inserted into the bolt insertion hole 86 and the collar 82 from one side plate 34 of the first pedal bracket 28, and a flanged nut 90 is formed from the other side plate 34. By being screwed together, the brake pedal 10 is supported by the intermediate portion 30 </ b> C of the second pedal bracket 30 so as to swing around the mounting bolt 88.

Further, in relation to the mounting bolt 88, the width of the notch 58 at the bottom of the notch 58 in the side plate portion 34 of the first pedal bracket 28 is made shorter than the shaft diameter of the mounting bolt 88. Mounting bolt 88
A pair of protrusions 92 (see FIG. 4) are formed to protrude along the bolt circumferential direction.

Next, the configuration of the slide plate 66 disposed substantially on the vehicle rear side of the pedal bracket 26 will be described in detail. [Structure of the slide plate 66] As shown in FIGS. 1 and 2, substantially on the vehicle rear side of the above-mentioned pedal bracket 26, a pipe-shaped high-strength member as a "second vehicle body-side member" is provided. An instrument panel reinforcement 94 is provided. The instrument panel reinforcement 94 is a member that has been conventionally arranged, and is arranged with the longitudinal direction substantially in the vehicle width direction.

A steering support 96 is mounted at a predetermined position in the longitudinal direction of the instrument panel reinforcement 94. Further, a rear end portion 30A of the second pedal bracket 30 is located at a position adjacent to the steering support 96.
A slide plate 66 as a “guide member” is fixed to a position on the rear side of the slide plate 66.

The slide plate 66 has a substantially U-shaped cross section with a substantially open upper side of the vehicle, and is a high-strength member like the instrument panel reinforcement 94. further,
The bottom surface of the slide plate 66 is formed into a curved surface having a predetermined radius of curvature, and forms a guide surface 66A of the rear end 30A of the second pedal bracket 30.

Next, the operation and effect of this embodiment will be described. When an external force equal to or more than a predetermined value acts on the front portion of the vehicle, the load at that time may be input to the dash panel 16 via the master cylinder 22 and the brake booster 20. In this case, as shown in FIG. 2, the dash panel 16 is displaced substantially toward the rear of the vehicle, and accordingly, the cowl inner panel 18 is also displaced substantially toward the rear of the vehicle.

On the other hand, instrument panel reinforcement 9
4 and the slide plate 66 attached thereto are both high-strength members.
Even if the extension 38B side of the rear end mounting bracket 38 fixed to the front end of the slide plate 66 abuts on the front end of the slide plate 66, the slide plate 66 side hardly displaces toward the rear of the vehicle.

For this reason, the first pedal bracket 28 receives a load from the base plate portion 32 side substantially toward the rear of the vehicle, but the extension portion 3 of the rear end mounting bracket 38.
A load (abutting reaction force) substantially toward the front of the vehicle is input from the 8B side. Further, openings 56 are formed in the pair of side plate portions 34 of the first pedal bracket 28 so that the rigidity in the vehicle longitudinal direction is set to be low. As a result, the first pedal bracket 28 buckles substantially in the vehicle longitudinal direction, and at the same time, the cowl inner panel 18 buckles substantially in the vehicle longitudinal direction.

In this way, a relative displacement is generated between the dash panel 16 and the instrument panel reinforcement 94, and the first
When the pedal bracket 28 and the cowl inner panel 18 buckle substantially in the vehicle front-rear direction, the rear end portion 30A of the second pedal bracket 30 comes into contact with the guide surface 66A of the slide guide plate 66. Second pedal bracket 30
When the rear end 30A abuts on the guide surface 66A, a pressing force substantially downward of the vehicle acts on the rear end 30A around the swing center axis 60 due to the curved shape of the guide surface 66A. . For this reason, the caulking portion 64 that maintains the connected state of the side plate portion 34 of the first pedal bracket 28 and the side plate portion 62 of the second pedal bracket 30 is maintained.
Is plastically deformed, and the combined state of both is released.

Thereafter, the rear end 30A of the second pedal bracket 30 is moved to the guide surface 66A of the slide plate 66.
Along the second pedal bracket 3
0 is rotationally displaced about the swing center axis 60 substantially downward of the vehicle. Along with this, the pivot center axis of the brake pedal 10 (that is, the mounting bolt 88) pivotally supported by the second pedal bracket 30 also moves along the notch 58 while plastically deforming the pair of projections 92. It is rotationally displaced substantially below the vehicle. Thereby, the pedal pad 70 of the brake pedal 10 is displaced substantially toward the front side of the vehicle.

In other words, according to this embodiment, it is possible to control the pedal pad 70 of the brake pedal 10 to be displaced substantially toward the front of the vehicle when an external force equal to or more than a predetermined value acts on the front of the vehicle. It becomes possible. As a result, according to the present embodiment, the bending of the knees of the legs due to the inertial movement of the occupant when an external force equal to or more than the predetermined value acts on the front portion of the vehicle can be suppressed, and thus the knees of the occupant's legs can be suppressed. Can be kept away from the steering column.

Further, according to the present embodiment, the slide plate 66 having the curved guide surface 66A is used to rotationally displace the rear end portion 30A of the second pedal bracket 30 substantially downward of the vehicle. Therefore, the displacement amount and displacement direction of the rear end portion 30A of the second pedal bracket 30 can be easily controlled by adjusting the radius of curvature and the shape of the guide surface 66A. As a result, according to the present embodiment, the effect of controlling the displacement of the pedal pad 70 of the brake pedal 10 substantially toward the front of the vehicle can be enhanced.

Further, according to the present embodiment, the caulking section 6
By appropriately adjusting the press depth of No. 4, it is possible to easily change the setting of the separation load of the second pedal bracket 30 from the first pedal bracket 28. That is, there is a degree of freedom in setting the detachment load of the second pedal bracket 30 from the first pedal bracket 28. Therefore, by adjusting the detachment load, the load input from the rear end portion 30A of the second pedal bracket 30 to the instrument panel reinforcement 94 can be reduced.

Further, according to the present embodiment, the pedal bracket 26 is divided into the first pedal bracket 28 and the second pedal bracket 30, so that the first pedal bracket 28 on the vehicle body side (the dash panel 16 and the cowl). Basically, there is no need to change the design of the mounting portion (the base plate portion 32 and the rear end mounting bracket 38) to the side bracket 52). Therefore, there is no need to change the design on the vehicle body side.

Further, according to the present embodiment, since the pedal bracket 26 is divided into the first pedal bracket 28 and the second pedal bracket 30, the mounting rigidity of the mounting portion of the first pedal bracket 28 on the vehicle body side. Do not affect the displacement characteristics of the rear end 30A of the second pedal bracket 30. Therefore, the rear end portion 30A of the second pedal bracket 30 can be reliably rotationally displaced substantially downward of the vehicle.

In addition, the shape of the second pedal bracket 30 (particularly, the rear end portion 30A) can be freely set so that the displacement characteristic of the second pedal bracket 30 becomes a desired one.

In this embodiment, the present invention is applied to a suspended main brake pedal. However, the present invention is not limited to this, and may be applied to vehicle pedals such as a suspended clutch pedal and a parking brake pedal. It is also possible to apply the present invention.

In this embodiment, the arc-shaped notch 58 is formed in the side plate portion 34 of the first pedal bracket 28.
However, the present invention is not limited to this, and the notch forming portion may be thinned to be easily broken, and a guide for defining the movement locus of the mounting bolt 88 serving as the pivot center axis of the brake pedal 10. Any configuration that can be grasped as a unit or a guide means is applicable.

Further, in the present embodiment, the notch 58 is formed in an arc shape having a uniform width. However, the present invention is not limited to this. For example, the formation of the notch in the shape of a flared arc has the following advantages. That is,
When an external force equal to or greater than a predetermined value acts from diagonally forward of the vehicle,
In many cases, the dash panel 16 is not displaced in a parallel movement substantially toward the rear side of the vehicle. In such a case as well, if the shape of the notch is formed in an arc shape with a flared skirt, the mounting bolt 88 can be smoothly removed from the notch.

In this embodiment, the connecting means for preventing the side plate portion 34 of the first pedal bracket 28 and the side plate portion 62 of the second pedal bracket 30 from moving relative to each other when the brake pedal 10 is normally operated. However, the present invention is not limited to this. Usually, the second pedal bracket 30 does not swing around the swing center axis 60 with respect to the first pedal bracket 28,
Any configuration can be applied as long as the configuration can release the coupling state between the two when an external force equal to or more than a predetermined value acts on the front portion of the vehicle.

For example, as shown in FIG. 7, a configuration may be adopted in which the side plate portion 34 of the first pedal bracket 28 and the side plate portion 62 of the second pedal bracket 30 are connected by rivets 98. In this case, when an external force equal to or greater than a predetermined value acts on the front portion of the vehicle and a shear load equal to or greater than the predetermined value acts on the rivet 98, the rivet 98 breaks and the connection between the side plates 34 and 62 is released. .

Further, in the present embodiment, the rear end mounting bracket 38 is attached to the rear end of the first pedal bracket 28 as a separate component by spot welding. However, the present invention is not limited to this. Pedal bracket 2
8, the rear end of the top plate portion 36 is formed to be substantially longer toward the rear side of the vehicle than that of the present embodiment, and is bent substantially toward the upper side of the vehicle so that the rear end mounting bracket 3
8 can be abolished.

In this embodiment, the extension 38B of the rear end mounting bracket 38 mounted on the rear end side of the first pedal bracket 28 is attached to the cowl side bracket 52 by using the mounting bolt 50 and the weld nut 54. The dash panel 16 is fixed so that it does not come off.
The extension portion 38 </ b> B may be detached from the cowl-side bracket 52 in accordance with the rearward displacement.

For example, if the component shape and the like of the present embodiment are not changed, the bolt insertion hole 48 formed in the extension 38B is formed slightly larger than the shaft diameter of the mounting bolt 50, and It is possible to adopt a configuration in which the setting is made in advance so as to reduce the margin for the head.
In this case, as shown in FIG.
Is displaced substantially to the rear side of the vehicle and the first pedal bracket 28
In the process of buckling substantially in the longitudinal direction of the vehicle,
Around the bolt insertion hole 48 is plastically deformed,
B is detached from the head of the mounting bolt 50.

There are various configurations grasped as such detaching means. For example, the upper portion of the extension portion 38B is bent substantially toward the front of the vehicle and a slit is formed in the upper portion, so that an external force of a predetermined value or more is applied to the front of the vehicle. When acting on the part, the mounting bolt 5
0 may move relatively along the slit and may be pulled out.
May be welded by spot welding, and when an external force equal to or more than a predetermined value acts on the front portion of the vehicle, the extension 38 </ b> B may be separated from the cowl-side bracket 52 and separated.
