Abstract

PROBLEM TO BE SOLVED: To control the displacement of the tread of a vehicular pedal when an external force not smaller than a predetermined value works on the front of the vehicle. SOLUTION: A brake pedal 22 and a brake booster 36 are both supported against a bracket 46 secured to inner panel reinforcement 16. A pressure member 52 is mounted in a position across a cowl 12 and a dash panel 14 and has its rear end portion 52A made to abut to the upper end portion 42A' of a first bracket part 42. Therefore, when an external force not smaller than a predetermined value works on the front of the vehicle, the first bracket part 42 is pressed approximately toward the back of the vehicle by the pressure member 52, so rotating and displacing the entire bracket 46 approximately toward the top of the vehicle. Thereby the brake pedal 22 supported against a second bracket part 44 is also displaced approximately toward the front and top of the vehicle.

Description

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 the 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 according to the present invention, comprising: a suspended vehicle pedal having a tread surface at a lower end portion to which an occupant's treading force is applied; A first vehicle-body-side component that is displaced substantially rearward when an external force greater than or equal to a value acts on the front of the vehicle, and is disposed substantially rearward of the vehicle than the first vehicle-body component, and the external force acts A hydraulic pressure conversion means provided between the high-strength second vehicle body-side component member which hardly displaces substantially toward the vehicle rear side and converts the treading force applied to the tread surface to a hydraulic pressure; A pedaling force transmitting member that connects the hydraulic pressure converting means to the hydraulic pedal and transmits the pedaling force applied to the tread surface of the vehicle pedal to the hydraulic pressure converting means; A bracket for pivotally supporting and supporting the hydraulic pressure converting means; The first vehicle body-side component member is provided on the vehicle body-side component member, and the first vehicle body-side component member is displaced substantially toward the rear side of the vehicle, so that a pressing force is applied to the bracket in a predetermined direction to move the bracket to the second vehicle body-side component member. And a displacement control means for rotating and displacing the mounting point substantially toward the upper side of the vehicle.

According to a second aspect of the present invention, there is provided a vehicle pedal displacement control structure according to the first aspect, wherein the bracket has a bracket upper portion located above the second vehicle body component member. The upper portion of the bracket receives a pressing force substantially toward the rear of the vehicle by the displacement control means when an external force equal to or more than a predetermined value acts on the front portion of the vehicle.

According to the first aspect of the present invention, the first vehicle-body-side component and the first vehicle-body-side component that are displaced substantially rearward when an external force greater than a predetermined value acts on the front of the vehicle. The liquid pressure converting means is also disposed between the high-strength second vehicle body side component member which is disposed substantially on the vehicle rear side and hardly displaces substantially toward the vehicle rear side even when the external force acts. The basic premise is that the pressure converting means and the suspension type vehicle pedal are connected by a pedaling force transmitting member.

When an external force equal to or more than a predetermined value acts on the front portion of the vehicle, the external force displaces the first vehicle body-side component substantially toward the rear of the vehicle. For this reason, the displacement control means provided on the first vehicle body side component also displaces substantially toward the vehicle rear side. On the other hand, since the second vehicle body side component member has high strength,
Even if the external force acts on the front part of the vehicle, it is hardly displaced substantially toward the rear side of the vehicle. For this reason, the bracket attached to the second vehicle body-side component and pivotably supporting the vehicle pedal and supporting the hydraulic pressure conversion means hardly displaces substantially toward the vehicle rear side. From these facts, when the displacement control means is displaced substantially to the rear side of the vehicle, the displacement control means applies a pressing force in a predetermined direction to the bracket. As a result, the bracket is rotationally displaced substantially toward the upper side of the vehicle around the point of attachment to the second vehicle body-side component. Accordingly, the (pedal surface of) the vehicle pedal pivotally supported by the bracket is also displaced substantially toward the front of the vehicle and substantially toward the upper side of the vehicle.

According to the second aspect of the present invention, the bracket has an upper portion of the bracket located above the second vehicle body-side component member, and the upper portion of the bracket has an external force greater than a predetermined value. During the operation on the front part of the vehicle, the displacement control means receives a pressing force substantially toward the rear side of the vehicle. The moment acts reliably. Therefore, the (pedal surface of) the vehicle pedal pivotally supported by the bracket is also reliably displaced substantially toward the front of the vehicle and substantially toward the upper side of the vehicle.

In particular, according to the present invention, the bracket includes an upper portion of the bracket positioned above the second vehicle-side component member, and the bracket upper portion is provided on the first vehicle-side component member. Therefore, it can be realized with the simplest configuration.

Corresponds to the “first vehicle body-side constituent member”.

On the substantially rear side of the dash panel 14 and on the inner side of the instrument panel 10, a "second vehicle body side component" having a longitudinal direction substantially in the vehicle width direction.
The instrument panel reinforcement 16 is provided. The instrument panel reinforcement 16 is formed in a pipe shape and is a high-strength member.

Between the dash panel 14 and the instrument panel reinforcement 16, a pedal support portion 18 bent into a predetermined shape and a pedal pad 20 as a “tread surface” attached to a lower end portion of the pedal support portion 18 are provided. The suspension type brake pedal 22 is disposed.

One end of a push rod (operating rod) 30 as a "pedal force transmitting member" is relatively rotatably connected to the upper end 18A of the pedal support 18 by a clevis 32 and a clevis pin 34. The push rod 30 extends substantially rearward of the vehicle starting from the clevis 32, and a rear end (the other end) of the push rod 30 is applied to the pedal pad 20 and increases the pedaling force of the occupant transmitted through the push rod 30. The brake is connected to a brake booster (brake booster) 36 that generates a predetermined pressure for braking.

The brake booster 36 is provided with a master cylinder 38 for converting the pressure increased by the brake booster 36 into a hydraulic pressure, and the master cylinder 38 is adapted to follow a change in the volume of the hydraulic system. Reservoir tank 40 for storing and refilling brake fluid
Are provided integrally. The push rod 30
And a master cylinder 38 that converts the increased pressure into a hydraulic pressure, which includes both the brake booster 36 that increases the occupant's treading force transmitted by the vehicle and the master cylinder 38 that corresponds to the hydraulic pressure conversion means. .

In addition, it should be noted that the layout described above is often adopted in a cab-over type automobile.

Here, the above-mentioned instrument panel reinforcement 16 is provided with a bracket 46 constituted by a first bracket portion 42 and a pair of second bracket portions 44.

More specifically, the first bracket portion 4
Reference numeral 2 denotes a rectangular flat plate-like bottom wall portion 42A arranged in parallel to the brake booster 36, and both sides of the bottom wall portion 42A are bent substantially toward the rear of the vehicle and extend parallel to each other. And a pair of side wall portions 42B. The brake booster 36 is disposed so as to face the bottom wall portion 42A of the first bracket portion 42.

Each of the second bracket portions 44 has a mounting portion 44A which is in close contact with the front surface of the bottom wall portion 42A of the first bracket portion 42, and is bent substantially forward from the mounting portion 44A in a side view. Extension portion 44B having a substantially right triangle shape
And is constituted by. This second bracket part 4
Reference numerals 4 are arranged on both sides of the front surface of the bottom wall portion 42A of the first bracket portion 42, respectively.

The rear ends of the pair of side walls 42B of the first bracket 42 have an arc shape, and the rear ends are fixed to the peripheral surface of the instrument panel reinforcement 16 by welding (rigid connection). Have been. Further, a stud bolt 48 protruding from the brake booster 36 is inserted through a bottom wall portion 42A of the first bracket portion 42 and a mounting portion 44A of each second bracket portion 44 through a cylindrical collar (not shown). The second bracket portion 44 and the brake booster 36 are fixed before and after the bottom wall portion 42 </ b> A of the first bracket portion 42 by screwing the nut 50 to the penetrating end of the stud bolt 48.

Further, the distal ends of the pair of extending portions 44B in the above-mentioned second bracket portion 44 are
2 is disposed on the side of the bent portion near the upper end portion 18A, and the above-described mounting bolt 24 is inserted from one end portion and the nut 26 is screwed on the other end portion, so that the brake is provided. The pedal 22 is pivotally supported pivotally.

At a position extending from the lower rear end of the cowl 12 to the upper end of the dash panel 14, a pressing member 52 as a relatively high-strength "displacement control means" projecting substantially toward the rear of the vehicle is disposed. Has been established. The rear end portion 52A of the pressing member 52 is bent downward in a hook shape, and the upper end portion 4 of the bottom wall portion 42A of the first bracket portion 42 described above.
It is in contact with the front of 2A '. The bottom wall 42
The upper end 42A 'in A is instrument panel reinforcement 1
6 and is located substantially above the vehicle.
2A 'corresponds to the "bracket upper part" of the second aspect.

Next, the operation and effect of this embodiment will be described. As shown by the solid line in FIG. 1, when the brake is not operated, the brake pedal 22 is held at the position shown by the solid line by the urging force of a return spring (not shown). In this state, the occupant moves the brake pedal 22
When the pedaling force is applied to the pedal pad 20, the brake pedal 22 swings substantially around the rotation shaft 28 toward the front of the vehicle, and the push rod 30 is pressed substantially toward the rear of the vehicle.
As a result, the pedaling force applied to the pedal pad 20 by the occupant is applied to the brake booster 36 via the push rod 30.
And is converted to hydraulic pressure by the master cylinder 38.

When an external force equal to or more than a predetermined value acts on the front portion of the vehicle, the dash panel 14 and the cowl 12 are displaced substantially to the rear of the vehicle as shown by a two-dot chain line in FIG. There is. In this case, the pressing member 52 disposed over the dash panel 14 and the cowl 12 is also displaced substantially toward the rear of the vehicle as shown by the two-dot chain line in FIG.

On the other hand, since the instrument panel reinforcement 16 which is arranged substantially rearward of the vehicle with respect to the dash panel 14 is a high-strength member, even if the external force acts on the front part of the vehicle, it is almost displaced substantially rearward of the vehicle. do not do. For this reason, the brake pedal 2 is fixed to the instrument panel reinforcement 16.
The bracket 46 that pivotally supports the bracket 2 and supports the brake booster 36 and the like is hardly displaced substantially toward the rear side of the vehicle.

Accordingly, when the pressing member 52 is displaced substantially to the rear of the vehicle, the bottom wall portion 42A of the first bracket portion 42
A relatively large pressing force from the rear end 52A of the pressing member 52 to the substantially rearward side of the vehicle is applied to the upper end 42A ′ of the pressing member 52. Since the upper end portion 42A 'of the bottom wall portion 42A is located substantially above the vehicle with respect to the instrument panel reinforcement 16, as a result, the rotational moment about the instrument panel reinforcement 16 substantially toward the upper side of the vehicle is reduced.
Acts on 6. As a result, the bracket 46 is attached to the instrument panel reinforcement 16 as shown by a two-dot chain line in FIG.
It is rotationally displaced around substantially upward of the vehicle. At this time, the pair of side wall portions 4 in the first bracket portion 42
While the upper edge side of 2B is plastically deformed, the bracket 46 is rotationally displaced generally toward the upper side of the vehicle.
In other words, when such a pressing force acts on the bracket 46 from the pressing member 52, the rigidity of the pair of side wall portions 42B of the first bracket portion 42 is adjusted so that the bracket 46 is rotationally displaced substantially upward in the vehicle. (Specifically, the plate thickness and the like) are tuned.

As described above, when the bracket 46 is rotationally displaced substantially upward of the vehicle, the pedal pad 20 of the brake pedal 22 pivotally supported by the second bracket portion 44 of the bracket 46 is also shown by a two-dot chain line in FIG. Thus, the vehicle is displaced substantially toward the front of the vehicle and substantially toward the upper side of the vehicle. That is, according to the present embodiment, when an external force equal to or more than a predetermined value acts on the front portion of the vehicle, control is performed such that the pedal pad 20 of the brake pedal 22 is largely displaced substantially toward the front of the vehicle and substantially toward the upper side of the vehicle. Becomes possible. As a result, it is possible to suppress 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, and thus it is possible to keep the knees of the occupant's legs away from the steering column. .

Further, according to the present embodiment, when the brake pedal 22 is rotationally displaced, the brake booster 36
At the same time, the rotational displacement is substantially upward of the vehicle, which also helps prevent interference between the brake booster 36 and the occupant's knee.

Further, in the present embodiment, the bracket 46 is provided at the upper end 4 of the bottom wall portion 42A of the first bracket portion 42 located above the instrument panel reinforcement 16.
2A ′, and the pressing member 5 having the upper end portion 42A ′ disposed over the dash panel 14 and the cowl 12.
2, the structure is pressed substantially rearward of the vehicle, so that the structure can be simplified.

Further, in the present embodiment, the upper end portion 42A 'of the bracket 46 is pressed substantially toward the rear side of the vehicle by the pressing member 52 disposed so as to protrude from the cowl 12 side, whereby the bracket 46 is moved toward the instrument panel reinforcement 16. Since it is configured to be rotationally displaced substantially upward of the vehicle around the mounting point, for example, the pedal bracket that supports the suspension-type vehicle pedal so as to be swingable is intentionally buckled substantially in the longitudinal direction of the vehicle. The pedal pad 20
The rigidity of the bracket 46 can be increased as compared with a type in which the bracket 46 is displaced substantially toward the front of the vehicle. Therefore, the support rigidity of the brake pedal 22 can be increased. [Second Embodiment] Next, a second embodiment will be described with reference to FIG. Note that the same components as those of the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 2, in this embodiment, when the upper end portion 42A 'of the bottom wall portion 42A of the first bracket portion 42 is pressed substantially rearward by the pressing member 52, the bracket 46 is moved. It is characterized in that it is configured to be easily rotationally displaced substantially upward of the vehicle. Specifically, it is characterized in that a plurality of beads 60 for lowering rigidity are integrally formed at a predetermined portion (a portion where plastic deformation occurs) on the upper edge side of the pair of side wall portions 42B of the first bracket portion 42. Thereby, the rigidity of the predetermined portion on the upper edge side of the pair of side wall portions 42B in the direction along the upper edge is partially reduced.

According to the above configuration, the same operation and effect as those of the first embodiment can be obtained. In addition, since the bead 60 is formed so that plastic deformation easily occurs, an external force of a predetermined value or more is applied to the front portion of the vehicle. Brake pedal 2 when activated
2 can be quickly rotationally displaced substantially forward of the vehicle and substantially upward of the vehicle.

Further, since no separate component is added, the structure does not become complicated. The pressing member 52
In order to facilitate the plastic deformation of the pair of side wall portions 42B when a pressing force is applied from above, in addition to providing the above-described bead 60, a notch or a long hole is provided, or only that portion is provided. Various configurations, such as a bent portion, can be applied, and any configuration that can be grasped as a fragile portion or a low-rigidity portion is applicable. Third Embodiment Next, a third embodiment will be described with reference to FIG. Note that the same components as those of the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted.

In the first and second embodiments described above, it is assumed that the rear end of the first bracket portion 42 is rigidly connected to the instrument panel reinforcement 16 by welding, and the pressing force from the pressing member 52 is provided. While the subject is how the bracket 46 is rotationally displaced substantially upward of the vehicle at the time of operation, in the present embodiment,
It is characterized in that the first bracket portion 42 itself is positively rotated around the instrument panel reinforcement 16 when the pressing force is applied, so that the bracket 46 is rotationally displaced substantially upward of the vehicle.

Specifically, as shown in FIG.
A first clamp 70 whose inner diameter matches the outer diameter of the instrument panel reinforcement 16 is fixed to the rear end of the bracket 42 by welding or the like. The first clamp 70 is fixed to the outer peripheral surface of the instrument panel reinforcement 16 by welding or the like. However, the first clamp 70
The welding strength to the instrument panel reinforce 16 does not separate with respect to the load applied during the normal operation of the brake pedal 22, and an external force equal to or more than a predetermined value acts on the front portion of the vehicle, and the welding force from the rear end portion 52A of the pressing member 52 The strength is set so as to be easily peeled off when a pressing load equal to or more than a predetermined value acts substantially on the rear side of the vehicle.

On the other hand, a second clamp 72 of the same shape is fitted to the fixing portion of the first clamp 70 in the instrument panel reinforcement 16 from the opposite side (substantially the rear side of the vehicle). The second clamp 72 is an instrument panel reinforce 1
6 and is connected only to both ends of the first clamp 70 by bolts 74 and nuts 76.

According to the above configuration, an external force equal to or greater than a predetermined value acts on the front portion of the vehicle, and the rear end portion 52A of the pressing member 52 causes the upper end portion 42A 'of the bottom wall portion 42A of the first bracket portion 42 to be formed.
Is pressed substantially to the rear side of the vehicle, the welding portion of the first clamp 70 to the instrument panel reinforcement 16 is peeled off.
Therefore, the coupling state between the first clamp 70 and the instrument panel reinforcement 16 is released. However, the first clamp 7
0 and the second clamp 72 are connected by the bolt 74 and the nut 76, so that the bracket 46
The whole is in a state of being rotatably supported on the instrument panel reinforcement 16 by the first clamp 70 and the second clamp 72. Therefore, the bracket 46 is connected to the pressing member 52.
By the pressing force from the vehicle, it can be easily rotationally displaced substantially upward of the vehicle, and the pedal pad 20 of the brake pedal 22 can be displaced more quickly substantially forward of the vehicle and substantially upward of the vehicle.

In this embodiment, the first clamp 70
Only the instrument panel was fixed (temporarily fixed) to the instrument panel reinforcement 16 by welding or the like for the following reason. Primarily,
This is because the positional accuracy of the mounting of the bracket 46 supporting the brake booster 36 and the brake pedal 22 to the instrument panel reinforcement 16 is ensured before the mounting work of the second clamp 72 is performed. Secondly, if an attempt is made to maintain the assembled state only by the tightening force of the first clamp 70 and the second clamp 72 on the instrument panel reinforcement 16, the first
When the bracket portion 42 receives the pressing force from the pressing member 52, the sliding resistance between the inner peripheral surfaces of the first clamp 70 and the second clamp 72 and the outer peripheral surface of the instrument panel reinforcement 16 increases, and the rotational displacement of the bracket 46 is increased. This is because it becomes resistance.

From this point of view, instead of fixing (temporarily fixing) only the first clamp 70 to the instrument panel reinforcement 16 by welding or the like, fixing only the second clamp 72 to the instrument panel reinforcement 16 in advance by welding or the like (temporary fixing). Fixed). Further, if the second reason (the point at which the sliding resistance increases) is negligible in taking measures when an external force equal to or more than a predetermined value acts on the front portion of the vehicle, the first clamp 70 and the first clamp 70 Second clamp 7
It is not necessary to temporarily fix one of the two to the instrument panel reinforcement 16 by welding or the like.

In each of the embodiments described above, 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 a suspended clutch pedal or the like. Is also applicable. In a case where the present invention is applied to a clutch pedal, the clutch master cylinder corresponds to the "hydraulic pressure converting means".

In each of the above-described embodiments, the rear end portion 52A of the pressing member 52 causes the first bracket portion 4 located substantially above the vehicle than the instrument panel reinforcement 16 to be located.
2, the upper end portion 42A 'of the bottom wall portion 42A is pressed substantially rearward of the vehicle, but in the relationship with the invention described in claim 1, the bracket 46 is positioned substantially below the instrument panel reinforcement 16 below the instrument panel reinforcement 16. A configuration in which the bracket 46 is rotationally displaced substantially upward of the vehicle by pressing the located portion substantially toward the rear of the vehicle is also included. For example, a pressed portion provided with a tapered surface capable of converting a pressing force substantially toward the rear of the vehicle into a pressing force substantially toward the upper side of the vehicle is integrally or separately provided on the bottom wall portion 42A of the first bracket portion 42. (In this case, the pressed portion needs to be located substantially below the instrument panel reinforcement 16 in the vehicle), and the tapered surface of the pressed portion is pressed by the pressing member. You may do so.

[0047]

A high-strength second vehicle-side component member that is disposed substantially rearward of the vehicle relative to the first vehicle-side component member and hardly displaces substantially rearward of the vehicle even when the external force is applied; The basic premise is that the hydraulic pressure converting means is disposed between the hydraulic pressure converting means and the suspension type vehicle pedal by a pedal force transmitting member. A bracket for pivotally supporting the vehicle pedal and supporting the hydraulic pressure conversion means is attached to the vehicle body side component member, and the first vehicle body side component member is attached to the first vehicle body side component substantially at the rear of the vehicle. To the bracket in a predetermined direction Displacement control means for applying pressure to rotate and displace the bracket substantially upward of the vehicle around the point of attachment to the second vehicle-side component is provided, so that an external force of a predetermined value or more acts on the front portion of the vehicle. In this case, there is an excellent effect that the displacement of the tread surface of the vehicle pedal can be controlled.

According to a second aspect of the present invention, in the vehicle pedal displacement control structure according to the first aspect, the bracket has an upper portion of the bracket positioned above the second vehicle body side component.
