A master cylinder 22 that functions as a conversion means and a reservoir tank 24 that stores and replenishes brake fluid following a change in volume of the hydraulic system are integrally provided.

  On the other hand, on the rear side of the dash panel 16, a pipe-like instrument panel reinforcement 26, which is a high-strength and high-rigidity vehicle-body-side component that is arranged with the vehicle width direction as a longitudinal direction, is disposed. An instrument panel bracket 28 as a support member is fixed at a predetermined position in the longitudinal direction of the instrument panel reinforcement 26. The instrument panel bracket 28 includes a pair of left and right side wall portions 28A and a bottom wall portion 28B that connects lower end portions of these side wall portions 28A in the vehicle width direction, and the vehicle upper side is opened when viewed from the vehicle front side. It is formed in a U shape. The rear end portions of the pair of left and right side wall portions 28A of the instrument panel bracket 28 are formed in an arc shape in accordance with the outer shape of the instrument panel reinforcement 26, and the rear end portions are fixed to the outer peripheral surface on the front side of the instrument panel reinforcement 26 by welding or the like. Has been. In a state where the instrument panel bracket 28 is fixed to the instrument panel reinforcement 26, the instrument panel bracket 28 extends from the instrument panel reinforcement 26 side to the vehicle front side in a cantilevered state. Further, the bottom wall portion 28B of the instrument panel bracket 28 is formed in a curved shape having a convex shape on the vehicle upper side in a side view. The degree of curvature of the bottom wall portion 28B is optimized in relation to the amount of rotational displacement of the pedal bracket 30 described later.

  Between the dash panel 16 and the instrument panel bracket 28 described above, a pedal bracket 30 that supports the brake pedal 10 as a vehicle pedal so as to be swingable is disposed. The pedal bracket 30 is arranged in parallel to the dash panel 16 and constitutes a mounting seat surface for the dash panel 16, and extends substantially parallel to the vehicle rear side from the vicinity of both sides of the base plate part 38. A pair of left and right side plate portions 40 and a top plate portion 41 disposed between the upper end portions of the pair of left and right side plate portions 40 so that the vehicle lower side is as a whole. It is formed in an open U shape.

  Cylindrical collars 42 are fixed to the four front corners of the base plate portion 38. The base plate portion 38 is configured to insert the stud bolt 44 protruding from the brake booster 20 into the collar 42 and screw the nut 46 from the vehicle interior space 14 side in a state where the collar 42 is in contact with the dash panel 16. Thus, it is fixed to the dash panel 16. Accordingly, the pedal bracket 30 is fixed and supported only on the dash panel 16. A dash insulator (not shown) used as a sound insulating material is interposed between the dash panel 16 and the base plate portion 38. A substantially L-shaped bending deformation portion 48 is set on the front side of the side plate portion 40 (between the base plate portion 38 and a mounting bolt 74 described later). When a compressive load in the longitudinal direction of the vehicle acts on the side plate portion 40, the bending deformation portion 48 is used as a starting point for bending deformation (see FIGS. 3 and 4). Furthermore, the top plate portion 41 is bent in a U shape in a side view, and a slide portion 50 that protrudes toward the rear side of the vehicle is integrally formed at the rear end portion. When the slide part 50 is viewed from the side, a predetermined amount protrudes from the upper corner of the rear end of the side plate part 40 toward the vehicle rear side, and further toward the upper side of the vehicle from the upper end flat part 41A of the top plate part 41. Projecting a predetermined amount.

  A suspension type brake pedal 10 is swingably supported in the vicinity of the middle portion in the longitudinal direction of the pair of left and right side plate portions 40 in the pedal bracket 30 described above. The brake pedal 10 includes a pedal arm 70 formed in a substantially square shape in a side view, and a pedal pad 72 as a tread surface that is attached to a lower end portion of the pedal arm 70 and is applied with a treading force of an occupant (driver). , Is composed of. At the middle of the pedal arm 70 in the height direction, the tip of a push rod (an element grasped as a treading force transmission member in a broad sense) 60 disposed through the dash panel 16 from the shaft core portion of the brake booster 20. The parts are connected to each other by a clevis 62 formed in a U shape in plan view and a clevis pin 64 penetrating both sides of the clevis 62 so as to be relatively rotatable.

  A circular hole is formed in the upper end portion of the pedal arm 70, and a cylindrical pedal boss (not shown) is fixed to the circular hole by caulking or the like in a penetrating state. Therefore, the brake pedal 10 is integrated with the pedal boss. Cylindrical bushes with hooks are fitted into both ends of the pedal boss in the axial direction, and a cylindrical collar is inserted into both bushes, and in this state, it is disposed between the pair of left and right side plate portions 40. After that, the mounting bolt 74 is inserted from the outside of one side plate portion 40 and a nut (not shown) is screwed from the outside of the other side plate portion 40, so that the brake pedal 10 swings around the mounting bolt 74. It is pivotally supported. Note that one end of a return spring (not shown) is locked at a predetermined position of the pedal arm 70, and constantly urges the brake pedal 10 to return to the initial position (position shown in FIG. 1).

  Here, the slide bracket 80 is attached to the lower surface side of the bottom wall portion 28B of the instrument panel bracket 28 described above. The slide bracket 80 is formed in a bowl shape when viewed from the front side of the vehicle, has the same curved surface shape as the bottom wall portion 28B, and is fixed to the bottom wall portion 28B by welding or the like, and the guide portion 80A. The bent portion 80B is bent from the side edge in the vehicle width direction (console box side) to the vehicle lower side. The total length of the guide portion 80A is set slightly longer on the vehicle rear side than the total length of the bottom wall portion 28B. The bent portion 80B is preventive so that the slide portion 50 does not come out inward in the vehicle width direction from the guide surface of the guide portion 80A when the slide portion 50 of the pedal bracket 30 slides on the guide portion 80A. Exists as a regulatory wall.

  The above-mentioned instrument panel bracket 28 and slide bracket 80 are greatly extended toward the front side of the vehicle as compared with the conventional one. 1 is indicated by an arrow X. In the following description, the extended arrow X portion of the instrument panel bracket 28 is referred to as an “instrument panel extension portion 82”, and the slide bracket 80 is extended. The portion of the arrow X is referred to as “slide bracket extension 84”.

  A sub slide bracket 86 is disposed on the upper surface side of the bottom wall portion 28B of the instrument panel bracket 28 described above. The sub-slide bracket 86 is formed by bending a rectangular flat plate that is long in the vehicle front-rear direction with the same curvature as the bottom wall portion 28B of the instrument panel bracket 28, and the rear end portion 86A is directed radially inward (to the brake pedal 10 side). It is bent. In the assembled state of the sub slide bracket 86 to the instrument panel bracket 28, the sub slide bracket 86 is placed between the left and right side wall portions 28A of the instrument panel bracket 28 and arranged in contact with the upper surface of the bottom wall portion 28B. ing. Accordingly, the sub-slide bracket 86, the bottom wall portion 28B of the instrument panel bracket 28, and the guide portion 80A of the slide bracket 80 are arranged in a three-layered state. Further, in the assembled state, the rear end portion 86A of the sub slide bracket 86 is arranged so as to cross the movement locus of the slide portion 50 of the pedal bracket 30 described above beyond the rear end portion of the guide portion 80A of the slide bracket 80. Has been.

  Further, a long hole 88 having a predetermined length extending in the vehicle front-rear direction is formed in the intermediate portion in the width direction of the front portion 86B (see FIG. 2) of the sub slide bracket 86. Correspondingly, bolt insertion holes 90 and 92 are formed in the bottom wall portion 28B of the instrument panel bracket extension portion 82 and the guide portion 80A of the slide bracket extension portion 84 at positions where they overlap with the rear end portion of the long hole 88, respectively. Has been. The fixing bolt 94 is inserted into the bolt insertion holes 90 and 92 and the long hole 88, and the nut 96 is screwed with a predetermined torque, whereby the sub slide bracket 86 is connected to the instrument panel bracket extension 82 and the slide bracket extension. It is fastened together with the portion 84. Since the slide bracket extension portion 84 is fixed to the instrument panel bracket extension portion 82 by welding or the like, there is no relative movement between them, but the sub slide bracket 86 is long due to the fastening torque of the fixing bolt 94 and the nut 96. Since it is only fixed to the bottom wall portion 28 </ b> B of the instrument panel bracket 28 through the hole 88, the length of the long hole 88 is obtained when a slide load greater than the fastening torque acts on the rear end portion 86 </ b> A of the sub slide bracket 86. In this range, relative movement (sliding) with respect to the instrument panel bracket 28 is possible. That is, the long hole 88 defines the movement stroke of the sub-slide bracket 86 and is an element grasped as a regulating means together with the fixing bolt 94 and the nut 96 in a broad sense.

  Further, a gate-shaped guide member 98 (a U-shape with the lower part opened) is attached to both side surfaces of the rear end portion of the slide bracket 80. In the assembled state, the sub slide bracket 86 is disposed inside the guide member 98.

  Furthermore, in the assembled state, the front end portion of the slide portion 50 of the pedal bracket 30 is near the middle portion in the front-rear direction of the slide bracket extension portion 84 (more precisely, slightly behind the rear end portion of the long hole 88). Facing the part).

  Next, the operation and effect of this embodiment will be described.

  During normal brake operation, as shown in FIG. 1, when the occupant applies a pedaling force to the pedal pad 72 of the brake pedal 10, the brake pedal 10 is substantially forward of the vehicle around the mounting bolt 74 (arrow A direction side). Is swung to. For this reason, the push rod 60 connected to the intermediate portion in the height direction of the pedal arm 70 of the brake pedal 10 is pressed toward the vehicle front side. When the push rod 60 is pushed substantially toward the front side of the vehicle, the pedaling force applied to the pedal pad 72 by the brake booster 20 is increased and converted to hydraulic pressure by the master cylinder 22. That is, the pedaling force applied to the pedal pad 72 of the brake pedal 10 is transmitted to the brake booster 20 and the master cylinder 22 via the push rod 60 and converted into a predetermined hydraulic pressure.

  Here, in the normal state shown in FIG. 1, when an external force of a predetermined value or more acts on the front of the vehicle, the load at that time is input to the dash panel 16 via the master cylinder 22 and the brake booster 20, The panel 16 may be displaced substantially to the vehicle rear side (arrow B direction side). In this case, as the dash panel 16 is displaced rearward, the pedal bracket 30 is also displaced toward the rear side of the vehicle. Therefore, the front end of the slide portion 50 disposed in a protruding state on the upper rear end of the pedal bracket 30 is the slide bracket 80. It abuts on the guide portion 80A. Since the guide portion 80A is formed in a predetermined curved shape with the upper side of the vehicle projecting, the slide portion 50 of the pedal bracket 30 slides on the guide surface of the guide portion 80A as shown in FIG. It is guided to the rear side and the vehicle lower side (arrow C direction). In this process, the left and right side plate portions 40 of the pedal bracket 30 are deformed starting from the bending deformation portion 48, and the rear end side of the pedal bracket 30 is rotationally displaced toward the vehicle rear side and the vehicle lower side. As a result, the pedal pad 72 of the brake pedal 10 is rotationally displaced substantially toward the front side of the vehicle (in the direction of arrow A). The above is the deformation behavior of the pedal bracket 30 in the first stage.

  Next, the deformation behavior of the pedal bracket 30 when an external force of a predetermined value or more acts on the front part of the vehicle during traveling at high speed will be described. In this case, the amount of displacement of the dash panel 16 toward the substantially rear side of the vehicle further increases as compared with the case shown in FIG. 3, so that the vehicle pedal displacement control structure according to the present embodiment is not applied. It is conceivable that the slide portion 50 of the pedal bracket 30 slides beyond the end of the guide portion 80A of the slide bracket 80, and the slide portion 50 is detached from the guide portion 80A.

  Here, in the present embodiment, the sub slide bracket 86 is slidably disposed on the bottom wall portion 28B of the instrument panel bracket 28, and the rear end portion 86A is disposed on the movement locus of the slide portion 50 of the pedal bracket 30. When the slide portion 50 of the pedal bracket 30 reaches the end of the guide portion 80A of the slide bracket 80, the slide portion 50 interferes with the rear end portion 86A of the sub slide bracket 86. For this reason, as shown in FIG. 4, the rear end portion 86A of the sub slide bracket 86 is pressed by the slide portion 50 in the extending direction (arrow D direction) of the guide surface of the guide portion 80A, and in the extending direction of the guide surface. Pulled out (slided). As a result, the rotational displacement of the slide portion 50 toward the vehicle rear side and the vehicle lower side is continued, and the pedal pad 72 is further rotationally displaced toward the vehicle front side accordingly. It should be noted that the pull-out amount of the sub slide bracket 86 is limited by the length of the long hole 88. That is, the stroke until the mounting bolt 74 is positioned from the rear end portion to the front end portion of the long hole 88 is the moving stroke of the sub slide bracket 86, and the rotational displacement of the rear end side of the pedal bracket 30 when the sub slide bracket 86 is fully stroked. Is regulated (stopped). The above is the deformation behavior of the second stage pedal bracket 30.

  Thus, in this embodiment, the sub slide bracket 86 that substantially extends and forms the guide surface of the guide portion 80A of the slide bracket 80 is disposed on the bottom wall portion 28B of the instrument panel bracket 28, and the slide portion 50 of the pedal bracket 30 is provided. Since the guide surface of the guide portion 80A is further extended after a full stroke on the guide surface of the guide portion 80A, a necessary rotational displacement amount can be given to the rear end side of the pedal bracket 30.

  In addition, since the sub slide bracket 86 is stored and held in a state of being superimposed on the bottom wall portion 28B of the instrument panel bracket 28 during normal pedal operation, the sub slide bracket 86 fits in a compact space within the installation space of the instrument panel bracket 28. Therefore, the foot space of the passenger is not reduced. In particular, in recent automobiles, a knee column module and the like are disposed in addition to a steering column in a passenger's foot space, and there are many parts. Also, considering the passenger's footing and convenience, it is better to have as wide a space as possible. For this reason, by adopting this structure in which the sub slide bracket 86 is housed in the instrument panel bracket 28 during normal pedal operation, the foot space of the occupant can be secured to the same extent as in the past.

  In summary, according to the pedal displacement control structure for a vehicle according to the present embodiment, a foot space for the occupant can be secured, and the brake pedal 10 is swung when an external force exceeding a predetermined value acts on the front portion of the vehicle. Necessary displacement is given to the pedal bracket 30 that can be supported, and the pedal pad 72 of the brake pedal 10 can be rotationally displaced by a necessary amount toward the front side of the vehicle.

  Further, according to the present embodiment, the rotational displacement of the rear end portion of the pedal bracket 30 is stopped when the sub slide bracket 86 has made a full stroke, so that the rear end portion of the pedal bracket 30 is the slide bracket 80 and the sub slide bracket. 86 does not leave the slide guide means. Therefore, it is possible to prevent the rear end portion of the pedal bracket 30 from entering the foot space of the occupant.

  In relation to the above, in the present embodiment, when the sub-sliding bracket 86 has made a full stroke, the rotational displacement of the rear end portion of the pedal bracket 30 is stopped, and thereafter the dash panel 16 is displaced to the vehicle rear side. In this case, a load is input to the instrument panel reinforcement 26 via the sub slide bracket 86 and the instrument panel bracket 28. However, according to the rotational displacement amount of the rear end portion of the pedal bracket 30 until the sub slide bracket 86 is fully stroked. Therefore, the input load is consumed (absorbed) by the deformation of the pedal bracket 30. Therefore, even if a load is input to the instrument panel reinforcement 26, the load after being sufficiently reduced is input.

[Second Embodiment]
Hereinafter, a second embodiment of the pedal displacement control structure for a vehicle according to the present invention will be described with reference to FIGS. In addition, about the same component as 1st Embodiment mentioned above, the same number is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 5, in the second embodiment, the above-described sub slide bracket 86 is not placed on the upper surface of the bottom wall portion 28 </ b> B of the instrument panel bracket 28, but the bottom wall portion 28 </ b> B of the instrument panel bracket 28. And the guide portion 80A of the slide bracket 80 are characterized in that they are held (may be sandwiched).

  That is, in the second embodiment, the guide portion 80A of the slide bracket 80 is not fixed to the bottom surface of the bottom wall portion 28B of the instrument panel bracket 28 in a surface contact state, but the guide portion 80A is not fixed to the bottom wall portion of the instrument panel bracket 28. 28B is fixed to the side wall portion 28A of the instrument panel bracket 28, etc. with a gap 100 corresponding to at least the plate thickness of the sub slide bracket 86.

(Action / Effect)
Also with the above configuration, as shown in FIG. 6 and FIG. 7, the operation itself is the same as that of the first embodiment described above, and therefore the same operation and effect as the first embodiment described above can be obtained. Furthermore, according to the present embodiment, the sliding operation of the sub slide bracket 86 is guided by the bottom wall portion 28B of the instrument panel bracket 28 and the guide portion 80A of the slide bracket 80, so the guide member used in the first embodiment described above. 98 becomes unnecessary. Therefore, the number of parts can be reduced and the structure can be simplified.

Although the bending deformation portion 48 is set in the above, various configurations other than the setting of the bending deformation portion 48 can be adopted. For example, it is possible to adopt a configuration in which a bead or an opening is provided in advance on a portion of the pedal bracket to be deformed, and the rigidity of the lower edge side of the pedal bracket with respect to the longitudinal load is intentionally reduced.
