Description

  The present invention relates to a support structure for a vehicle pedal supporting a vehicle pedal disposed in a foot space of a driver's seat.

  When an external force acts from the front of the vehicle, it is conceivable that a dash panel (toe board) that divides the engine compartment and the compartment is deformed to the compartment side, and the foot space of the driver's seat is reduced. When the foot space of the driver's seat is reduced, there is a possibility that the driver's foot (shine, knee) may interfere with the vehicle pedal (brake pedal). Therefore, a technique for suppressing the interference between the driver's foot (shine, knee) and the brake pedal has been conventionally proposed (see Patent Document 1).

  In the technique disclosed in Patent Document 1, the vehicle rear portion of the pedal bracket is detachably connected to a member on the vehicle body side, and when the dash panel moves rearward, the vehicle rear portion of the pedal bracket is moved downward by the inclined surface. The brake pedal is configured to move relative to the front side of the vehicle.

  As a result, even if an external force acts from the front of the vehicle and the dash panel is deformed to the passenger compartment side and the foot space of the driver's seat is reduced, the brake pedal moves relative to the front side of the vehicle and the driver's foot It is possible to suppress the interference between the (skin, knee) and the brake pedal.

  However, since the technique of patent document 1 has connected the vehicle rear side part of the pedal bracket so that it can detach | leave, the connection mechanism (fastening structure) is interposing. For this reason, a movement for releasing the connection with the vehicle body side member is required, and a movement for releasing the connection and a movement for moving the brake pedal are required to move the brake pedal. However, the amount of deformation of the dash panel to the cabin side was required much.

  In addition, the timing for releasing the connection and the movement of the pedal bracket may vary due to variations in the fastening force in the fastening structure, variations in the assembled state, variations in friction between the pedal bracket and the inclined surface, and the like. For this reason, there has been a case where the control of the movement of the brake pedal to the front side of the vehicle (retraction suppression) can not be stably performed.

Has been. One end of the stay member 16 is connected to the deck cross member 5 side, and the other end is configured to face the front end portion of the pedal bracket 11 in the vehicle front-rear direction.

  Then, when the pedal bracket 11 is retracted, the stay member 16 rotates to the lower end and the rear side of the vehicle with the one end of the stay member 16 (the end on the deck cross member 5 side) as a fulcrum (center). The tip end portion of the pedal bracket 11 is displaced downward to suppress the retraction of the brake pedal 12 (see FIG. 6).

  The detailed structure of the stay member 16 and the relationship between the stay member 16 and the deck cross member 5 and the pedal bracket 11 will be described below.

  As shown in FIGS. 1, 3, and 4, the stay member 16 extends obliquely downward in front of the vehicle from the deck cross member 5 side toward the pedal bracket 11 side, and is disposed on the deck cross member 5 side. A first stay 21 and a second stay 22 connected to the first stay 21 and disposed on the pedal bracket 11 side. That is, the first stay 21 and the second stay 22 are integrally formed so as to be arranged in the length direction of the stay member 16.

  One end of the stay member 16 on the rear side of the vehicle (one end) on the deck cross member 5 side (rear side of the vehicle) of the first stay 21 is a block-shaped deck cross bracket provided on the deck cross member 5. 14, the other end on the pedal bracket 11 side of the second stay 22, which is an end portion (the other end) of the stay member 16 on the front side of the vehicle, and the pedal block 15 provided at the distal end portion of the pedal bracket 11 and the vehicle. It is configured to face each other in the front-rear direction.

  The first stay 21 and the second stay 22 are connected via a connecting part (bending part) P1 so that the angle between them is a predetermined angle, and can be bent and deformed at the connecting part (bending part) P1. It is configured. Specifically, the stay member 16 is bent at the connecting portion (bent portion) P1, and the second stay 22 is arranged to be inclined downward at a predetermined angle with respect to the first stay 21. Yes.

  Then, as shown in FIG. 4A, the stay member 16 is bent and deformed at the connecting portion (bending portion) P1, so that the first stay 21 and the second stay 22 are connected to the connecting portion (bending portion) P1. It is relatively rotatable in the longitudinal direction of the vehicle about a horizontal axis extending in the width direction of the vehicle centering on That is, when the pedal bracket 11 is retracted due to a vehicle collision or the like, the other end (lower end) of the second stay 22 is pushed by the pedal bracket 11 (pedal block 15), so that the pedal bracket 11 is retracted. The second stay 22 is configured to rotate (deform) relative to the first stay 21 and to the vehicle rear side with respect to the connecting portion (bending portion) P1.

  For example, the first stay 21 and the second stay 22 are configured so that the angle formed between the first stay 21 and the second stay 22 is reduced at the initial stage of the retraction of the pedal bracket 11 (see FIGS. 6A and 6B) (counterclockwise in FIG. 1). ) In a rotational direction (deformation). The minimum angle of the angle which the first stay 21 and the second stay 22 make with each other is restricted by the rotation restricting means described later. That is, the rotation range of the second stay 22 relative to the first stay 21 is restricted by the rotation restricting means.

  In the present embodiment, the width of the connecting portion (bent portion) P1 is made larger than the width of the first stay 21 and the second stay 22 so that the stay member 16 is easily deformed at the connecting portion (bent portion) P1. It is formed to be narrow.

  As shown in FIGS. 1, 2, and 3, a flat plate-like first fixing piece 25 bent upward is formed at one end (end portion on the deck cross member 5 side) of the first stay 21 of the stay member 16. A bolt hole 25 a is formed in the first fixing piece 25. As shown in FIG. 4A, the first stay 21 is bent and deformed at the bending portion P2 of the first fixing piece 25 so that the bending portion P2 is centered with respect to one end (the first fixing piece 25). The vehicle can be rotated in the vehicle front-rear direction around a horizontal axis extending in the vehicle width direction.

  More specifically, the first stay 21 rotates with respect to the deck cross bracket 14 in the vehicle lower side and the rear side (counterclockwise direction in FIG. 1) according to the retraction amount when the pedal bracket 11 retreats ( 6) (see FIG. 6C). First flanges 26 extending downward are respectively provided at both side edges along the length direction of the first stay 21, and the first stay 21 has a U-shaped cross section opened downward. (See FIG. 5A). The rigidity of the first stay 21 is improved by providing the first flange 26.

  The first stay 21 is provided with a first flange 26 in which the front surface of the vehicle is fixed to the rear surface of the deck cross bracket 14 with a bolt in a state where the first fixing piece 25 is bent upward. The non-side surface (upper surface) is kept in surface contact with the lower surface of the deck cross bracket 14 (see FIG. 1).

  That is, the first stay 21 is restricted at the position (predetermined position) of the lower surface of the deck cross bracket 14 at the forward position of the vehicle (the clockwise position in FIGS. 1 and 4). In the state, one end (first fixing piece 25) is supported rotatably (deformable) in the vehicle longitudinal direction about the horizontal axis extending in the vehicle width direction with respect to the deck cross bracket 14.

  The first fixed piece 25 is fixed to the surface of the deck cross bracket 14 on the vehicle rear side in a state in which the swing around the vertical axis is restricted.

  On the other hand, as shown in FIG. 1, FIG. 3, and FIG. 4A, one end of the second stay 22 of the stay member 16 is connected to the other end of the first stay 21 and the lower side with respect to the first stay 21. It is arranged in an inclined state. The second stay 22 can be turned in the vehicle front-rear direction around the connecting portion (bending portion) P1 by being bent and deformed at the connecting portion (bending portion) P1 with the first stay 21. The other end of the second stay 22 is disposed so as to face the pedal block 15 (pedal bracket 11), and a protrusion 41 extending toward the pedal block 15 is formed.

  On the other hand, a rectangular hole 42 as a fitting portion is formed in a surface (facing portion) facing the other end of the second stay 22 of the pedal block 15 (pedal bracket 11), and the second stay 22 is formed in the rectangular hole 42. The protrusion 41 is arranged in a state of being penetrated. The rectangular hole 42 is formed in a size that does not contact the protrusion 41 of the second stay 22 in a state where the protrusion 41 of the second stay 22 is penetrated.

  That is, normally, the pedal block 15 and the protrusion 41 of the second stay 22 are in a disengaged state, and the protrusion of the second stay 22 is inserted into the rectangular hole 42 when the pedal bracket 11 moves to the rear side of the vehicle. When 41 enters, the second stay 22 is engaged with the pedal block 15. An upper side of the rectangular hole 42 of the pedal block 15 is in contact with the second stay 22 when the stay member 16 is rotated rearward of the vehicle, so that the stay member 16 (second stay 22) rotates relative to the pedal block 15. A restricting portion 15a for restricting the moving range is formed.

  A second flange 28 extending downward is provided at both side edges along the length direction of the second stay 22, and a flange portion 28 a that opens outward is formed at the lower end of the second flange 28. Has been. The second flange 28 has a hat-shaped cross section opened downward (see FIG. 5B). The rigidity of the second stay 22 is improved by providing the second flange 28.

  As shown in FIG. 5, the distance H <b> 1 between the first flanges 26 of the first stay 21 is formed longer than the distance H <b> 2 between the second flanges 28 of the second stay 22, and the first flange 26 of the first stay 21. The width between is wide. The direction in which the angle between the first stay 21 and the second stay 22 (the angle of the second stay with respect to the first stay) is reduced, here, the second stay 22 is on the lower side and the vehicle rear side (in FIG. 1). When it is rotated by a predetermined amount (predetermined angle) in the counterclockwise direction), the first flange 26 of the first stay 21 and the flange portion 28a of the second flange 28 of the second stay 22 come into contact with each other. It is comprised so that rotation may be controlled.

  Accordingly, the rotation of the second stay 22 with respect to the first stay 21 relative to the vehicle rear side (counterclockwise direction in FIG. 1) is restricted more than a predetermined, and the angle formed by the first stay 21 and the second stay 22 is minimized. The angle is regulated (see FIG. 6B). That is, the first flange 26 and the second flange 28 for improving the rigidity of the first stay 21 and the second stay 22 constitute a rotation restricting means for restricting the rotation range of the second stay 22. .

  Further, as shown in FIGS. 3 and 4 (b), a convex portion 29a and a concave portion 29b are formed at corresponding portions of the first flange 26 and the flange portion 28a of the second flange 28, respectively. Is a mechanism to fit. Then, after the rotation of the second stay 22 with respect to the first stay 21 is restricted, the stay member 16 is integrated with the first stay 21 and the second stay 22 around the bent portion P2 of the first fixing piece 25. It is comprised so that it may be rotated by the vehicle back side (refer FIG.6 (c)).

  The rotation restricting means may be provided with a flange on the inner side of the end of the first flange 26 so that the second flange 28 having a narrow width is brought into contact with the flange. It is also possible to make the width of the first flange 26 narrower than the width of the second flange 28 and provide a flange that extends outward at the end of the first flange 26.

  The movement (rotational deformation) of the stay member 16 will be described in detail with reference to FIG.

  In a normal state in which the stay member 16 is not rotated, a portion where the other end (lower end) of the stay member 16 and the pedal block 15 (pedal bracket 11) are engaged, that is, a protrusion 41 of the second stay 22 (see FIG. 3) and the rectangular hole 42 (see FIG. 3) of the pedal block 15 are positioned at the position Q1.

  When the pedal bracket 11 (pedal block 15) (see FIG. 3) is retracted due to a collision or the like and the second stay 22 of the stay member 16 is pushed backward, the second stay 22 is moved downward with respect to the first stay 21. Since it is bent so as to be inclined, the stay member 16 (see FIG. 3) is first deformed at the connecting portion (bending portion) P1, and the second stay 22 is illustrated with the connecting portion (bending portion) P1 as a fulcrum (center). Is rotated counterclockwise to the vehicle rear side (downward side). By the rotation of the second stay 22, the pedal bracket 11 (pedal block 15) is guided rearward while moving rearward.

  Here, the load transmitted to the deck cross member 5 through the stay member 16 at the initial stage of the collision when the stay member 16 is bent and deformed at the connecting portion (bent portion) P1. Because the reaction force received from the stay member 16 can be suppressed by absorbing the movement of the pedal bracket 11, the movement of the pedal bracket 11 is smoothly performed.

  Due to the rotation of the second stay 22 with respect to the first stay 21, the engagement point P3 of the lower end (projection 41) of the second stay 22 (stay member 16) moves from the position of Q1 to the second flange 28 of the second stay 22 and the second stay 28. The first flange 26 of the first stay 21 is displaced along the trajectory S1 to a position Q2 where the first flange 26 abuts. Thereby, the tip of the pedal bracket 11 is pushed down to the position of Q1 to Q2.

  When the lower end of the stay member 16 is further pushed backward while the second stay 22 is in contact with the first stay 21, the stay member 16 is fixed to the deck cross bracket 14 (see FIG. 1). The first stay 21 and the second stay 22 are integrally rotated around the bent portion P2 of the piece 25, with the bent portion P2 serving as a fulcrum (center), and rotated counterclockwise in the drawing to the rear side (downward side) of the vehicle. The At this time, the locus of the engagement point P3 at the other end of the stay member 16 changes from S1 to S2.

  When the rotation of the stay member 16 advances, the engagement point P3 moves from the position of Q2 to the position of Q3 where the stay member 16 (second stay 22) and the restricting portion 15a of the pedal block 15 come into contact with each other. And the tip of the pedal bracket 11 is further pushed down to the position of Q2 to Q3.

  When the lower end of the stay member 16 is pushed further rearward and the engagement point P3 is rotated rearward beyond the position of Q3, the stay member 16 moves to the rear side of the vehicle with the bent portion P2 as a fulcrum (center) (see FIG. (The counterclockwise direction in the figure), that is, the first stay 21 with respect to the first stay 21 with respect to the first stay 21 with respect to the vehicle front side (clockwise in the figure). The second stay 22 starts to rotate in the direction in which the angle is expanded. At this time, the locus of the engagement point P3 at the other end of the stay member 16 changes from S2 to S3.

  As the stay member 16 further rotates, the engagement point P3 is moved rearward from the position where the line connecting the bent portion P2 of the stay member 16 and the engagement point P3 extends in the vertical direction, and the bent portion of the stay member 16 is moved. It is displaced along the trajectory S3 to the position of Q4 where the distance between P2 and the engagement point P3 is the longest. Thereby, the tip of the pedal bracket 11 is further pushed down to the position of Q3 to Q4.

  Thus, the engagement point P3 engaged with the pedal bracket 11 at the lower end of the stay member 16 (the other end of the second stay 22) is displaced from Q1 to Q4 through Q2, Q3, and Q3 along the trajectories S1, S2, and S3. As a result, the tip of the pedal bracket 11 is configured to be pushed downward in a stepwise manner.

  Based on the structure of the stay member 16, the operation of the support structure for a vehicle pedal with the above configuration will be described with reference to FIG.

  FIG. 6 shows the operation of the support structure for a vehicle pedal according to one embodiment of the present invention, and FIG. 6 (a) shows the state before the pedal bracket (dash panel) is retracted (normal state) 6 (b) shows a state in which the pedal bracket (dash panel) starts retreating (for example, a state in the initial stage of the collision), and FIG. 6 (c) shows a state in which the pedal bracket (dash panel) further retracts (for example, in the middle of the collision). 6 (d) is a state in which the pedal bracket (dash panel) is further retracted backward (for example, in a state after the collision).

  As shown in FIG. 6A (as shown in FIG. 1), in the normal case, the first fixing piece 25 of the first stay 21 is fixed to the surface of the deck cross bracket 14 on the vehicle rear side. The upper surface of the stay 21 is in surface contact with the lower surface of the deck cross bracket 14. Further, the projection 41 of the second stay 22 is disposed to penetrate through the rectangular hole 42 of the pedal block 15. In this state, the first flange 26 of the first stay 21 and the second flange 28 of the second stay 22 are separated by a predetermined distance. That is, the angle formed by the first stay 21 and the second stay 22 is set to an angle at which the flanges do not hit each other.

  For example, when the dash panel 3 is deformed to the vehicle compartment side (rear) due to the collision and the pedal bracket 11 is retracted rearward, the protrusion 41 of the second stay 22 enters the rectangular hole 42 of the pedal block 15, and the pedal block 15 is engaged with the second stay 22. Then, the lower end of the stay member 16, that is, the other end of the second stay 22 is pushed backward by the pedal block 15 (the pedal bracket 11).

  The stay member 16 is bent so that the second stay 22 is inclined downward with respect to the first stay 21, and the rotation of the first stay 21 toward the vehicle front side (upper side) is restricted by the deck cross bracket 14. Therefore, the stay member 16 is deformed at the connecting portion (bent portion) P1, and the second stay 22 is rearward of the vehicle with respect to the first stay 21 with the connecting portion (bent portion) P1 as a rotation fulcrum (center). It bends to the side (downward side) (it turns to the counterclockwise direction in FIG. 5).

  Then, when the second stay 22 rotates by a predetermined angle with respect to the first stay 21, as shown in FIG. 6B, the flange 28a of the second flange 28 of the second stay 22 is the first stay 21. The convex portion 29a and the concave portion 29b are engaged with each other to restrict the rotation (the bending angle) of the second stay 22 with respect to the first stay 21 to the rear side of the vehicle.

  Here, when the pedal block 15 moves and the projection 41 of the second stay 22 enters the rectangular hole 42, there is a gap between the rectangular hole 42 and the projection 41, so the pedal bracket 11 Even if there is a variation in the direction of the compressive load, the protrusion 41 of the second stay 22 surely enters the rectangular hole 42 of the pedal block 15, and the second stay 22 is securely engaged with the pedal block 15. Can do.

  Further, since the angle of the second stay 22 is inclined downward with respect to the first stay 21, when the pedal bracket 11 is retracted, the stay member 16 is bent and deformed at the connecting portion (bending portion) P1, The reaction force acting on the pedal bracket 11 from the stay member 16 can be suppressed, and the turning direction of the second stay 22 can be reliably guided to the lower side, that is, the vehicle rear side (counterclockwise in the figure). .

  When the distal end of the pedal bracket 11 is pushed downward by the second stay 22 due to the rotation of the second stay 22 relative to the first stay 21 toward the vehicle rear side (downward side), the base end portion of the pedal bracket 11 is It bends and the tip of the pedal bracket 11 is pushed down. Thereby, the brake pedal 12 (the tread surface 12a) relatively moves to the vehicle front side (left side in the drawing).

  Incidentally, the protrusion 41 of the second stay 22 is deformed in a state in which the engagement of the pedal bracket 11 with the pedal block 15 is maintained in response to the rotation of the second stay 22. The relative rotation of the two stays 22 (stay members 16) is permitted.

  When the pedal bracket 11 is further retracted from the state of FIG. 6B, the rotation of the second stay 22 is restricted, that is, the flange portion 28 a of the second flange 28 of the second stay 22 and the first stay 21. Since the lower end of the stay member 16 (the other end of the second stay 22) is pushed further toward the vehicle rear side in a state in which the concave portion 29 of the first flange 26 is fitted, the first fixing is performed as shown in FIG. The bent portion P2 of the piece 25 is deformed, and the first stay 21 and the second stay 22 are integrated with the deck cross bracket 14 (deck cross member 5) with the bent portion P2 as a rotation fulcrum (center). Rotate to the vehicle rear side (counterclockwise direction in the figure).

  Since the first stay 21 and the second stay 22 rotate integrally from the state of FIG. 6B, the tip of the pedal bracket 11 is further pushed down and displaced downward, so that the brake pedal 12 (the tread 12a) Moves relatively to the front side of the vehicle (left side in the figure).

  Then, when the pedal bracket 11 is further retracted from the state of FIG. 6C and the second stay 22 comes into contact with the restricting portion 15a of the pedal block 15 (see FIG. 4), the first stay 21 and the second stay 22 are placed. Rotates further toward the vehicle rear side (counterclockwise direction in the figure) with respect to the deck cross bracket 14 centering on the bending portion P2 (see FIG. 4), and at the same time, the second stay 22 Around the connecting portion (bent portion) P1 (see FIG. 4), the vehicle begins to turn in the vehicle front side (clockwise direction in FIG. 5), that is, in the direction in which the angle between the first stay 21 and the second stay 22 increases. .

  As a result, the stay member 16 is rotated while the entire length of the stay member 16 is increased, that is, the distance between the one end (first fixing piece 25) of the first stay 21 and the other end (projection 41) of the second stay 22 is increased. The tip of the pedal bracket 11 is pushed downward further, and the brake pedal 12 is further moved relative to the vehicle front side (left side in the figure).

  Then, the connecting portion (bent portion) P1 between the first stay 21 and the second stay 22 of the stay member 16 is fully extended (the distance between one end of the first stay 21 and the other end of the second stay 22 is maximized). Then, the protrusion 41 of the second stay 22 falls out of the rectangular hole 42 of the pedal block 15, and the engagement between the two is released.

  That is, when the tip end of the pedal bracket 11 is largely pushed down, the engagement between the stay member 16 (second stay 22) and the pedal bracket 11 (pedal block 15) is released. The pedal bracket 11 is prevented from being lifted upward, and the brake pedal 12 is kept moved forward.

  Thus, even if an external force is applied from the front due to a frontal collision of the vehicle and the dash panel 3 is deformed to the passenger compartment 2 side and the foot space of the driver's seat is reduced, the brake pedal 12 is moved to the front side of the vehicle. By relative movement, interference between the driver's foot (shin, knee) and the brake pedal 12 can be suppressed.

  In addition, when the pedal bracket 11 moves backward, the pedal bracket 11 may be bent and enter depending on the input state. In the configuration of this embodiment, since the first fixing piece 25 of the first stay 21 is fixed with respect to the surface of the deck cross bracket 14 so that the rotation about the vertical axis is restricted, the first fixing piece 25 is fixed around the vertical axis of the stay member 16. Therefore, the influence on the rotation of the first stay 21 and the second stay 22 can be minimized.

  In addition, since the first flange 26 and the second flange 28 for increasing the rigidity and strength of the first stay 21 and the second stay 22 are used as the restricting means for restricting the rotation of the second stay 22, it is ensured with a simple configuration. The first stay and the second stay can be integrally rotated by restricting the rotation of the second stay relative to the first stay.

  Further, since the width of the first flange 26 of the first stay 21 is set wider than the width of the second flange 28 of the second stay 22, the rotation around the vertical axis of the stay member 16 (first stay 21). A large cross section with respect to the movement can be secured, and the rotation of the stay member 16 around the vertical axis is further suppressed.

  As described above, in the vehicle pedal support structure having the above-described configuration, the stay member 16 including the first stay 21 and the second stay 22 is simply disposed between the pedal bracket 11 and the deck cross member 5. With this configuration, when the pedal bracket 11 moves to the rear side of the vehicle, the tip of the pedal bracket 11 can be surely pushed down.

  Moreover, since the reaction force received from the stay member 16 when the pedal bracket 11 starts to move is suppressed by the rotation (bending deformation) of the second stay, the pedal bracket 11 is positively guided downward, so the pedal bracket 11 can be moved more smoothly and reliably. In addition, when the second stay rotates, the impact load input from the pedal bracket 11 to the deck cross member 5 via the stay member 16 can be absorbed.

  For this reason, the brake pedal 12 can be moved relative to the front of the vehicle reliably and smoothly with a simple structure without providing a separation mechanism for detaching the pedal bracket 11 and the like from the vehicle member and an inclined surface for guiding the pedal bracket 11 downward. It is possible to move to the side, and it is possible to stably control the movement (retraction suppression) of the brake pedal 12 to the vehicle front side against external force from the front of the vehicle.

  In the present embodiment, since the stay member 16 and the pedal bracket 11 are separated from each other in normal times, vibration during traveling is not transmitted via the stay member 16 and vibration toward the vehicle compartment side. Transmission can be suppressed.

  A second embodiment of the present invention will be described with reference to FIG.

  FIG. 7 shows a side view of the overall structure of the vehicle pedal support structure according to the second embodiment of the present invention. Here, only the parts different from the first embodiment will be basically described, and the parts having the same structure as the first embodiment (FIG. 1, FIG. 2) will be assigned the same reference numerals and overlapping explanations will be omitted.

  As shown in FIG. 7, the vehicle pedal support structure of the second embodiment has the other end (second stay) of the stay member 50 extending in the vehicle front-rear direction between the pedal bracket 11 and the deck cross member 5. 52) is fixed to the tip of the pedal bracket 11 (pedal block 15), and one end of the stay member 50 (one end of the first stay 51) is connected to the deck cross bracket 54 on the deck cross member 5 side in the vehicle front-rear direction. It is configured to face each other.

  One end of the second stay 52 of the stay member 50 is connected to the other end of the first stay 51, and the second stay 52 is inclined downward to the first stay 51 at a predetermined angle. The first stay 51 and the second stay 52 are bent at the connecting portion (bending portion) P1 so as to be relatively rotatable in the vehicle front-rear direction around the connecting portion (bending portion) P1.

  At the other end of the second stay 52, a flat plate-like second fixing piece 53 bent downward is provided, and the second fixing piece 53 is formed with a bolt insertion groove whose lower side is opened. . In a state where the second fixed piece 53 of the second stay 52 is bent downward, the front surface of the vehicle is fixed to the rear surface of the pedal block 15 via the bolt insertion groove. The second stay 52 is bent and deformed at the bent portion P4 of the second fixed piece 53, so that the second stay 52 is rotated around the horizontal axis extending in the vehicle width direction around the bent portion P4 with respect to the other end (second fixed piece 53). Thus, it is relatively rotatable in the vehicle front-rear direction.

  Specifically, the second stay 52 rotates in the vehicle front side (clockwise direction in FIG. 7) with respect to the pedal block 15 (pedal bracket 11) according to the retraction amount when the pedal bracket 11 retreats ( It is configured to be deformed. That is, when the second stay 52 rotates to the vehicle rear side around the connecting portion (bent portion) P1 with the first stay 51, the bent portion P4 is deformed at the same time so that the bent portion P4 is the center. The pedal block 15 is rotated relative to the vehicle front side.

  A deck cross bracket 54 is fixed to the deck cross member 5, and one end 51 a that extends toward the deck cross bracket 54 and faces the deck cross bracket 54 is formed at one end of the first stay 51 of the stay member 50. A concave portion 55 as a fitting portion is formed at a portion of the deck cross bracket 54 that faces the one end 51 a of the first stay 51.

  When the pedal bracket 11 moves to the rear side of the vehicle, the stay member 50 moves to the rear side of the vehicle, and the one end 51a of the first stay 51 is fitted into the recess 55 of the deck cross bracket 54. The stay member 50 is turnable in the vehicle front-rear direction with a fitting portion between the end 51a of the first stay 51 and the recess 55 of the deck cross bracket 54 as a fulcrum (center).

  In the second embodiment, when the pedal block 15 moves and the stay member 50 moves rearward of the vehicle, the first stay 51 is engaged when the one end 51a of the first stay 51 and the recess 55 of the deck cross bracket 54 are fitted. The one end 51a of the first stay 51 is securely attached to the recess 55 of the deck cross bracket 54 even if the direction of the compressive load on the pedal bracket 11 varies. So that the first stay 51 is securely engaged with the deck cross bracket 54.

  Note that the stay member 50 of the second embodiment operates in substantially the same manner as in the first embodiment (see FIG. 4A) when the pedal bracket 11 is retracted, and its operational effects are also the same. Is omitted.

  A third embodiment of the present invention will be described with reference to FIG.

  FIG. 8 shows a side view of the overall structure of the vehicle pedal support structure according to the third embodiment of the present invention. Here, only parts different from the first embodiment and the second embodiment will be basically described, and the same structure as in the first embodiment (FIG. 1, FIG. 2) and the second embodiment (FIG. 7) will be described. Are denoted by the same reference numerals and redundant description is omitted.

  As shown in FIG. 8, in the vehicle pedal support structure of the third embodiment, one end of the stay member 60 (one end of the first stay 61) is fixed to the deck cross bracket 14 and the other end of the stay member 60 (first The other end of the two stays 52 is fixed to the tip of the pedal block 15. That is, unlike the first and second embodiments, one end and the other end of the stay member 60 are fixed to the deck cross member 5 side member and the pedal bracket 11 side member, respectively. It is comprised so that the bracket 11 may be connected. In other words, the structure of the stay member 60 is a combination of the first stay 21 of the first embodiment and the second stay 52 of the second embodiment.

  One end of the second stay 62 of the stay member 60 is connected to the other end of the first stay 61, and the second stay 62 is inclined downward to the first stay 61 at a predetermined angle. The first stay 61 and the second stay 62 are bent and deformed at the connecting portion (bending portion) P1, so that the first stay 61 and the second stay 62 are relatively rotatable in the vehicle front-rear direction around the connecting portion (bending portion) P1.

  At one end of the first stay 61 of the stay member 60, a flat plate-like first fixing piece 25 bent upward is provided as in the first embodiment, and a bolt hole is formed in the first fixing piece 25. It is formed. In a state where the first fixing piece 25 of the first stay 61 is bent upward, the front surface of the vehicle is fixed to the rear surface of the deck cross bracket 14 through the bolt holes, and the first flange 26 is The surface (upper surface) of the first stay 61 that is not provided is in surface contact with the lower surface of the deck cross bracket 14. The first stay 21 is bent and deformed at the bent portion P2 of the first fixed piece 25, so that the first stay 21 is rotated around the horizontal axis extending in the vehicle width direction around the bent portion P2 with respect to one end (first fixed piece 25). The vehicle can be rotated in the longitudinal direction of the vehicle.

  The other end of the second stay 62 is provided with a flat plate-like second fixing piece 53 bent downward, and the second fixing piece 53 is formed with a bolt insertion groove whose lower side is opened. In a state where the second fixing piece 53 of the second stay 62 is bent downward, the front surface of the vehicle is fixed to the rear surface of the pedal block 15 via the bolt insertion groove. The second stay 52 is bent and deformed at the bent portion P4 of the second fixed piece 53, so that the second stay 52 is rotated around the horizontal axis extending in the vehicle width direction around the bent portion P4 with respect to the other end (second fixed piece 53). Thus, it is relatively rotatable in the vehicle front-rear direction.

  In the third embodiment, one end of the stay member 60, that is, one end of the first stay 61 is rotatably fixed to the deck cross member 5 side, and the other end of the stay member 60, that is, the other end of the second stay 62 is pedaled. Since it is rotatably fixed to the block 15 (the pedal bracket 11 side), the input from the pedal bracket 11 when the dash panel 3 is displaced to the vehicle rear side can be transmitted to the stay member 60 quickly and reliably. . For this reason, the front-end | tip of the pedal bracket 11 can be reliably displaced to the lower side at an early stage.

  In the case of the stay member 60 of the third embodiment, as in the second embodiment, substantially the same operation (see FIG. 4 (a)) as the first embodiment is obtained, and the operation and effect are also the same. I omit it.

  A fourth embodiment of the present invention will be described with reference to FIG.

  FIG. 9 shows a side view of the overall structure of the vehicle pedal support structure according to the fourth embodiment of the present invention. Here, only the parts different from the other embodiments will be basically described, and the parts having the same structure as in the other embodiments (FIG. 1, FIG. 2, FIG. 7, FIG. 8) The explanation is omitted.

  As shown in FIG. 9, in the vehicle pedal support structure of the fourth embodiment, one end of the stay member 20 (one end of the first stay 31) is fixed to the deck cross bracket 18, and the other end of the stay member 20 (first The other end of the two stays 32 is fixed to the tip of the pedal block 15. That is, as in the third embodiment, one end and the other end of the stay member 20 are fixed to a member on the deck cross member 5 side and a member on the pedal bracket 11 side, and the deck cross member 5 and the pedal bracket 11 are connected to each other. It is configured to connect.

  The other end of the first stay 31 and one end of the second stay 32 are connected at a predetermined angle, and the first stay 31 is arranged so as to incline upward with respect to the second stay 32. It is done. In other words, the second stay 32 is bent forward (upward) so as to be more horizontal to the first stay 31. That is, the stay member 20 has a shape that is bent in the opposite direction to the other embodiments at the connecting portion (bent portion P1).

  Further, the stay member 20 is bent and deformed at the connecting portion (bending portion) P1, so that the first stay 31 and the second stay 32 extend horizontally in the vehicle width direction with the connecting portion (bending portion) P1 as the center. It can be rotated relatively in the vehicle longitudinal direction around the axis. For example, the first stay 31 and the second stay 32 are arranged at the upper side of the vehicle and the front side of the vehicle so that the angle between the first stay 31 and the second stay 32 is reduced at the initial stage of retraction of the pedal bracket 11 (see FIGS. 1 in a clockwise direction) (displacement).

  One end of the first stay 31 of the stay member 20 is provided with a flat first fixing piece 35 bent upward, and the surface on the vehicle front side is in a state where the first fixing piece 35 is bent upward. The deck cross bracket 18 is fixed to the rear surface of the vehicle. The first stay 31 is rotatable in the vehicle longitudinal direction about a horizontal axis extending in the vehicle width direction centering on the bending portion P2 with respect to one end (the first fixing piece 25). First flanges 36 extending upward are respectively provided at both side edges along the length direction of the first stay 31, and the first stay 31 has a U-shaped cross section opened upward.

  The other end of the second stay 32 is provided with a flat plate-like second fixing piece 37 bent downward. With the second fixed piece 37 of the second stay 32 bent downward, the surface on the vehicle front side is fixed to the surface on the vehicle rear side of the pedal block 15. Second flanges 38 that extend upward are provided on both side edges along the length direction of the second stay 32, and flanges 38a that are open to the outside are formed on the upper ends of the second flanges 38, respectively. The second flange 38 has a hat-shaped cross section that opens upward. The second stay 32 is bent and deformed at the bent portion P4 of the second fixed piece 37, so that the second stay 32 is rotated around the horizontal axis extending in the vehicle width direction around the bent portion P4 with respect to the other end (second fixed piece 37). Thus, it is relatively rotatable in the vehicle front-rear direction.

  Further, a regulating member 19 that contacts the lower surface of the second stay 32 is provided on the upper surface of the pedal bracket 11 on the vehicle rear side (front end side) from the pedal block 15, and the second flange of the second stay 32 is provided. The surface (bottom surface) on the side where 38 is not provided is in surface contact with the upper surface of the regulating member 19.

  In the fourth embodiment, the first flange 36 of the first stay 31 and the second flange 38 of the second stay 32 constituting the rotation restricting means extend above the stay member 20, thereby The relative rotation of the second stay 22 with respect to the stay 21 in the clockwise direction in the drawing in a clockwise direction in the figure is restricted.

  In the fourth embodiment, the operation (rotational deformation) of the stay member 20 is different from the other embodiments. The operation of the vehicle pedal support structure having the above configuration will be described with reference to FIG.

  FIG. 10 shows the operation of the support structure for a vehicle pedal according to the fourth embodiment of the present invention, and FIG. 10 (a) shows the state before the pedal bracket (dash panel) is retracted (normal state) ), FIG. 10B shows a state in which the pedal bracket (dash panel) starts retreating (for example, a state in the initial stage of a collision), and FIG. 10C shows a state in which the dash panel further retreats (for example, a state in the middle of the collision). FIG. 10 (d) shows a state in which the dash panel is further retracted further (for example, the state at the late stage of the collision).

  In the normal state shown in FIG. 10 (a) (shown in FIG. 9), the first stay 31 and the second stay 32 are arranged at a predetermined angle. In this state, the first flange 36 of the first stay 31 and the second flange 38 of the second stay 32 are separated by a predetermined distance. That is, the angle formed by the first stay 31 and the second stay 32 is set to an angle at which the flanges do not hit each other.

  For example, when the dash panel 3 is deformed to the vehicle compartment side (rear) due to the collision and the pedal bracket 11 is retracted rearward, the other end (lower end) of the stay member 20 (second stay 22) is connected to the pedal block 15 (pedal bracket). 11) is pushed backward by The stay member 20 is bent so that the second stay 32 is inclined forward (upward) with respect to the first stay 31. Therefore, as shown in FIG. The second stay 32 is bent toward the vehicle front side (upper side) with respect to the first stay 31 with the connecting portion (bending portion) P1 as a rotation fulcrum (center) (see FIG. 9). Rotate clockwise). At the same time, the first stay 31 is bent toward the vehicle rear side (downward side) with the bent portion P2 (see FIG. 9) of the first fixed piece 35 as a rotation fulcrum (center) (rotates counterclockwise in the figure). ).

  Then, when the second stay 32 is rotated by a predetermined angle with respect to the first stay 31, as shown in FIG. 10B, the flange portion 38 a of the second flange 38 of the second stay 32 is moved to the first stay 31. Of the second stay 32 with respect to the first stay 31 (a bending angle) is restricted.

  By the rotation of the second stay 32 and the first stay 31, the restriction member 19 at the tip of the pedal bracket 11 is pushed downward by the bottom surface of the second stay 32, so that the base end portion of the pedal bracket 11 is bent and the pedal bracket 11 is bent. Is pushed down. Thereby, the brake pedal 12 (the tread surface 12a) is relatively moved to the vehicle front side (left side in the drawing). Here, by rotating the second stay 32 with respect to the first stay 31, the reaction force exerted on the pedal bracket 11 from the stay member 20 at the initial stage of the collision is suppressed.

  When the pedal bracket 11 is further moved backward from the state of FIG. 10B, as shown in FIG. 10C, the flange portion of the second flange 38 of the second stay 22 and the first flange 36 of the first stay 31. In the state in which the lower end of the stay member 20 (the other end of the second stay 32) is further pushed toward the rear of the vehicle, the bent portion P2 is set as a rotation fulcrum (center) with respect to the deck cross bracket 18. The first stay 31 and the second stay 32 are integrally pivoted to the rear side of the vehicle (counterclockwise in the figure).

  Since the first stay 31 and the second stay 32 rotate integrally from the state of FIG. 10B, the tip of the pedal bracket 11 is further pushed down and displaced downward, so that the brake pedal 12 (the tread 12a) Move relative to the vehicle front side (left side in the figure) (FIG. 10 (c)).

  Then, when the pedal bracket 11 is further retracted backward from the state of FIG. 10C, the first stay 31 and the second stay 32 are further rearward of the deck cross bracket 18 around the bent portion P2 (see FIG. 10). While rotating in the counterclockwise direction), at the same time, the second stay 32 with respect to the first stay 31 at the vehicle rear side (counterclockwise direction in FIG. 5) centering on the connecting portion (flexion portion) P1, ie, It starts to rotate in the direction in which the angle between the first stay 31 and the second stay 32 increases.

  The stay member 20 is connected to the other end (second fixed piece 37) of the second stay 32 and the pedal block 15 (pedal bracket 11), and is connected to one end (first fixed piece 35) of the first stay 31 and the deck. When the vehicle is pivoted from the connecting portion with the cross bracket 18 to the vehicle rear side, as shown in FIG. 10 (d), the overall length of the stay member 20 is extended, and the tip end portion of the pedal bracket 11 is pushed downward further. As a result, the brake pedal 12 moves relatively further to the vehicle front side (left side in the drawing).

  Further, when the pedal bracket 11 is retracted from the state of FIG. 10D and the connecting portion (bent portion) P1 between the first stay 31 and the second stay 32 of the stay member 20 is fully extended, the second stay 32 is moved. The fixing between the other end (second fixing piece 37) and the pedal block 15 is released, and the connection between the two is released. As a result, the deck cross member 5 or the like is pulled down by the pedal bracket 11 and displaced downward, or the pedal bracket 11 is prevented from being lifted upward, and the brake pedal 12 is moved forward of the vehicle. It is maintained in the state.

  Thus, even if the external force acts from the front of the vehicle and the dash panel 3 is deformed to the passenger compartment 2 side and the foot space of the driver's seat is reduced, the brake pedal 12 moves relative to the front side of the vehicle, Interference between the driver's foot (shine, knee) and the brake pedal 12 can be suppressed.

  In the vehicle pedal support structure of the fourth embodiment described above, as in the other embodiments, a release mechanism for detaching the pedal bracket 11 and the like from the vehicle member, an inclined surface for guiding the tip of the pedal bracket 11 downward, and the like are provided. Therefore, the brake pedal 12 can be moved relatively forward and reliably with a simple configuration, so that the movement of the brake pedal 12 to the front side of the vehicle is stable against external force from the front of the vehicle. Control becomes possible.

  As described above, according to the vehicle quantity pedal support structure of the present invention, the front end of the pedal bracket is displaced reliably and smoothly downward with a simple configuration, and the brake pedal is moved relatively forward of the vehicle. Since it can be made to do, it becomes possible to control stably the movement (retraction suppression) to the vehicle front side of a brake pedal to external force from the front of a vehicle.

  The present invention can be used in the industrial field of a support structure for a vehicle pedal.
