Description

  The present invention relates to a pedal device for a vehicle that suppresses a backward movement of the pedal arm by bending a support member such as a brake pedal, an accelerator pedal, or a clutch pedal in the event of a vehicle collision.

  When a vehicle such as an automobile collides, a pedal arm such as a brake pedal moves backward to reduce or prevent the possibility of damaging the feet of the driver. Has been proposed. For example, Patent Document 1 discloses a dash panel (dash panel 1) in which a support member (pedal bracket 3) that rotatably supports a pedal arm (brake pedal 4) is positioned in front of a deck cross member (deck cross pipe 9). In a pedal device for a vehicle configured to be attached to a guide slide contact portion (a guide cross-contact portion (guide 13) having a U-shaped cross-section directed downward is provided on the deck cross member and is fitted into the reverse suppression guide from below) A bracket 8) is provided at the rear end of the support member, and when the support member moves backward along with the dash panel toward the deck cross member due to a collision of the vehicle, the guide sliding contact portion moves downward along the backward movement suppression guide. The support member is pushed down to prevent the pedal arm from retreating according to the support member.

  The specific pedal device exemplified in Patent Document 1 is such that the guide sliding contact portion does not shift in the left-right direction even when the dash panel retreats unevenly by closing the lower surface of the retraction suppressing guide having a U-shaped cross section. The retraction restraining guide is surely guided. Thereby, the retraction direction of the support member that is pushed down by the guide sliding contact portion moving downward along the retraction suppression guide is limited, and the intended retraction suppression (displacement suppression) of the pedal arm is realized. In addition, the retraction suppressing guide whose bottom surface is blocked prevents the guide sliding contact portion from dropping and suppresses excessive movement of the guide sliding contact portion. The movement restraint of the guide sliding contact portion by the backward restraining guide is the backward restraining of the support member, and the backward restraining of the pedal arm.

JP 2002-211369 A (Claim 1, [0013], [0017] to [0022])

  Since the dash panel retraction is not uniformly determined by the collision mode of the vehicle, if the pedal arm is bounced up around the pivot axis, the purpose is to suppress the retraction of the pedal arm even if the support member is bent downward. Cannot reach enough. From this, in the pedal device of Patent Document 1, it is conceivable to tilt the retraction suppression guide in the horizontal direction, move the guide sliding contact portion in the horizontal direction, and tilt the pedal arm leftward or rightward. Here, since the pedal device of Patent Document 1 has the guide sliding contact portion fitted in the reverse restraining guide having a U-shaped cross section, when the backward restraining guide is inclined in the horizontal direction, the guide sliding contact portion is moved backward. Problems arise in moving along the restraining guide.

  If the retraction restraint guide is tilted in the horizontal direction, the peripheral edge (especially near the boundary between the front and side edges) of the guide sliding contact portion rubs against the inner side wall of the tilted retreat restraint guide, and friction is generated. To do. This friction hinders the smooth movement of the guide sliding contact portion, and causes a situation in which the back restraining of the support member according to the back restraining guide does not work well. Specifically, the guide sliding contact portion does not move along the retraction suppression guide unless a load that is greater than the design load assuming a vehicle collision occurs, and as a result, the pedal arm may not be able to suppress retraction.

  In the case of automobile members, it is desired to reduce the number of members, for example, in order to reduce the manufacturing cost as much as possible. In the pedal device of Patent Document 1, the guide sliding contact portion that accurately determines the posture with respect to the support member and needs to be firmly integrated requires two positioning bolts and fixing bolts. If the positioning bolt is omitted, there is a risk that the guide sliding contact portion will swing around the fixed bolt. Therefore, the friction during the movement of the guide sliding contact portion increases, and the pedal arm moves backward. This leads to problems that are more difficult to control.

  As described above, there is no problem when the backward restraining guide extends in line with the backward direction of the support member. However, when the backward restraining guide is tilted in the horizontal direction, the pedal device of Patent Document 1 causes the pedal arm to retract. It is understood that it becomes impossible to suppress well. Therefore, on the premise of the pedal device of Patent Document 1, the retraction suppression guide is inclined in the horizontal direction and the pedal arm is inclined leftward or rightward, and the guide sliding contact portion is formed by inclining the retraction suppression guide in the horizontal direction. To solve the problem of friction that hinders the smooth movement of

  As a result of the study, we developed a support member that supports the pedal arm so that it can rotate freely, and attaches it to the dash panel located in front of the deck cross member. And a guide sliding contact portion that is fitted to the reverse restraining guide from below is provided on the support member, and when the support member moves backward together with the dash panel toward the deck cross member due to a vehicle collision, the guide sliding contact portion is In the pedal device for a vehicle that suppresses the backward movement of the pedal arm according to the support member by moving downward along the backward restraining guide, the guide sliding contact portion has a circular periphery including the front edge in the moving direction. The guide sliding contact part is fitted from below into a retraction suppression guide that is formed in an arc shape and tilted in the horizontal direction. It is a non-pedal system.

  The pedal device of the present invention reduces the friction between the guide sliding contact portion that is fitted and moved from below into the retraction suppression guide and the side wall of the retraction suppression guide, so that the guide sliding contact portion that most directly rubs against the side wall is provided. The periphery including the leading edge in the moving direction is formed in an arc shape. Here, “the peripheral edge including the front edge in the moving direction is formed in an arc shape” means that the front edge in the moving direction of the guide sliding contact portion and the peripheral edge extending on both side edges following the front edge are continuous as a whole. It means that there is. The peripheral edge may be arc-shaped with a uniform radius as a whole, or a corner from the left edge to the front edge in the moving direction and a corner from the right edge to the front edge are formed in an arc shape, respectively, and the front edge It is good also as a circular arc shape which the whole periphery containing is continued as a whole. In this case, it is good to make it the left-right asymmetrical arc-shaped periphery which enlarged the radius of the corner | angular part on the opposite side (outside) with respect to the direction where the retraction suppression guide was inclined.

  The pedal device according to the present invention can swing when the guide sliding contact portion moves along the retraction suppression guide because the friction at the periphery of the guide sliding contact portion that is fitted into the retraction suppression guide and moves is reduced. Is reduced. Therefore, the guide sliding contact portion is provided with a guide engaging portion, the support member is provided with a member engaging portion, and the guide engaging portion of the guide sliding contact portion fixed to the support member by a fixing bolt is used as the member engaging portion of the support member. By engaging with the positioning bolt, the positioning bolt can be omitted as compared to the conventional (the pedal device of Patent Document 1). The engagement between the guide engaging portion and the member engaging portion positions the guide sliding contact portion with respect to the support member, and suppresses or prevents swinging of the guide sliding contact portion with the fixing bolt as an axis.

  Specifically, the guide sliding contact portion is provided with a guide engaging portion formed of a cut and raised protrusion, and the support member is provided with a member engaging portion formed of an engaging hole into which the protrusion is inserted, and a fixing bolt is provided on the support member. A guide that is a guide engaging portion of the fixed guide sliding contact portion is inserted into an engaging hole that is a member engaging portion of the support member, and is engaged with a peripheral edge of the engaging hole, and a guide using a fixing bolt as an axis. It is preferable to suppress or prevent swinging of the sliding contact portion. Here, if the cross-sectional shape of the protrusion from which the engagement hole is cut and raised is completely equal, the bending allowance of the protrusion cannot be accommodated in the engagement hole, and the guide sliding contact portion cannot be brought into close contact with the support member. Therefore, the engaging hole is made larger than the cross-sectional shape of the protrusion, and the cut and raised protrusion is engaged with the front edge or the rear edge of the engaging hole (the inner peripheral edge of the engaging hole facing the back or the belly of the protrusion). Good.

  According to the present invention, in the pedal device of Patent Document 1, the guide sliding contact portion can be smoothly moved even when the retraction suppression guide is tilted in the horizontal direction, and the retraction of the pedal arm can be better suppressed. This is because the peripheral edge including the leading edge in the moving direction of the guide sliding contact portion is formed in an arc shape, so that the surface pressure when the guide sliding contact portion collides the arc shaped front edge with the side surface of the retraction control guide. This is because the guide sliding contact portion can be moved along the retraction suppression guide without causing deformation of the side surface. The friction at the time of movement of the guide sliding contact portion is reduced by the peripheral edge, so that the guide sliding contact portion is attached to the support guide only by the fixing bolt, and the guide engaging portion and the member engaging portion are engaged. As a result of preventing the head swing, the number of bolts used is reduced, and the manufacturing cost can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a side view showing a pedal device to which the present invention is applied, FIG. 2 is a plan view of the pedal device of this example, and FIG. 3 is a view of a mounting bracket 26 fixed to the rear end of the support member 2 and a guide sliding contact portion 23. FIG. 4 is a cross-sectional view showing a state in which the mounting bracket 26 and the guide sliding contact portion 23 are assembled. FIG. 5 is a bottom view in a state in which the mounting bracket 26 and the guide sliding contact portion 23 are assembled. FIG. 6 is a plan view corresponding to FIG. 2 showing a state in which the support member 2 is retracted and the guide sliding contact portion 23 collides with the side surface 31 of the retraction suppression guide 3 in the event of a vehicle collision. FIG. 2 is a side view corresponding to FIG. 1 showing a state in which the guide sliding contact portion 23 is moved and the support member 2 is bent downward and rightward.

  The pedal device of this example is an example of a brake device in an ordinary automobile (vehicle). First, the configuration of the pedal device of this example will be described. As shown in FIGS. 1 and 2, the pedal device of this example is configured by attaching a support member 2 that rotatably supports the pedal arm 1 to a dash panel 4 positioned in front of the deck cross member 5. The The pedal arm 1 has a configuration in which a pedal pad 12 is attached to the lower end of an arm body 11 that is pivotally attached to an arm support portion 22 of a support member 2 via a pedal rotation shaft 13. The pedal device of this example is a brake device, which transmits the rotation of the arm body 11 to the control device as an advance / retreat amount of a link rod (not shown), for example, and operates the brake body in proportion to the advance / retreat amount of the link rod. .

  The support member 2 is provided with a member mounting portion 21 at the front end of an arm support portion 22 made of a bracket having a U-shaped cross section with its lower part open, and a guide sliding contact portion 23 via a mounting bracket 26 fixed to the rear end by welding or the like. Installed and configured. The arm support part 22 forms a mounting part vicinity bead 24 that is a highly rigid part near the front in the vicinity of the member mounting part 21, and extends in the left-right direction to a part where the member mounting part 21 and the mounting part vicinity bead 24 are close to each other. A virtual bending axis 27 is set (see FIG. 1). As a result, when the guide sliding contact portion 23 is moved down along the retraction suppressing guide 3, the support member 2 is bent downward with the virtual bending shaft 27 as an axis. The pedal arm 1 is pushed downward as the support member 2 is pushed down and bent because the arm main body 11 is pivotally attached to the arm supporting portion 22 behind the bead 24 in the vicinity of the mounting portion.

  The support member 2 of this example has the front end member mounting portion 21 attached to the dash panel 4, the rear end guide sliding contact portion 23 is bolted to the upper surface of the retraction restraining guide 3, and the support member 2 is connected to the dash panel 4. It is installed between the deck cross member 5. As described above, the support member 2 is provided with the attachment portion vicinity bead 24 in the arm support portion 22 and the pedal arm 1 is pivotally attached to the rear of the attachment portion vicinity bead 24, so that the rigidity is improved as a whole. Therefore, as described above, the installation state is stable by being installed between the dash panel 4 and the deck cross member 5. In addition, the support member 2 of this example is provided with an arm regulation guide 25 behind the arm body 11 in order to prevent the pedal arm 1 from being flipped up when the support member 2 is bent.

  The retraction suppression guide 3 has an H-shaped cross section composed of a downwardly sloped upper surface 32 that is gently curved downward and to the right, and a pair of parallel side surfaces 31 and 31 sandwiching the upper surface 32 (below the upper surface 32) With a bracket having a U-shaped cross section, a notch formed on the upper edge side of each side surface 31 is abutted and attached to the deck cross member 5 by welding or the like. In this example, in order to support the support member 2, as described above, the guide sliding contact portion 23 attached to the rear end of the support member 2 is bolted to the upper surface 32 of the retraction restraining guide 3 by the support bolt 28. is doing. As a result, the guide sliding contact portion 23 can move along the retraction restraining guide 3 immediately after it is detached from the support bolt 28. On the contrary, if the guide sliding contact portion 23 can move along the backward movement suppression guide 3 when the support member 2 is retracted, the guide sliding contact portion 23 may be bolted to a support member attached to the deck cross member 5 separately. Good.

  The present invention is characterized by a guide sliding contact portion 23 that smoothly moves along a downwardly inclined retreat suppressing guide 3 that is gently curved downward and to the right according to the upper surface 32. As shown in FIGS. 3 to 5, the guide sliding contact portion 23 of this example includes a sliding contact surface 235 that forms an arcuate front edge 231 by pressing a single plate material, and a cut and raised protrusion. This is an integral member having an inverted L-shape in side view, in which a mounting surface 236 formed with 233 and having bolt holes 234 opened is bent and continuous. In this example, a bent portion connecting the slidable contact surface 235 and the mounting surface 236 bulges opposite to the direction in which the slidable contact surface 235 is bent with respect to the mounting surface 236, and a wide T-shaped support hole is formed forward. 232 is provided at the bent portion, and the sliding contact surface 235 including the arcuate front edge 231 and the periphery of the mounting surface 236 are continuously bent with respect to the mounting surface 236 (in FIG. 4). A reinforcing flange 237 protruding in the right direction on the paper surface is provided to prevent a decrease in rigidity due to the support hole 232, the protrusion 233, and the bolt hole 234.

  The guide sliding contact portion 23 inserts and engages the projection 233 cut and raised in the engagement hole 261 formed in the mounting bracket 26, and fixes the fixing bolt 29 inserted from below through the bolt hole 234 to the mounting bracket 26. The nut 262 is screwed and bolted. Here, the protrusion 233 of the guide sliding contact portion 23 cannot be cut up from the mounting surface 236 completely perpendicularly. Therefore, the protrusion 233 of this example is the base of the bending margin, that is, the edge where the protrusion 233 starts to be raised from the mounting surface 236 is the rear edge of the engagement hole 261 (the inner peripheral edge on the lower side in FIG. 3 to FIG. 5). The mounting surface 236 is brought into close contact with the mounting bracket 26 by tightening the fixing bolt 29.

  Thus, even if the base of the bending margin of the protrusion 233 is engaged with the inner peripheral edge of the engagement hole 261, the protrusion 233 can sufficiently perform the positioning function if the attachment surface 236 is brought into close contact with the attachment bracket 26. Further, even if the guide sliding contact portion 23 tries to swing around the fixing bolt 29, the bending allowance of the projection 233 has to run on the inner peripheral edge of the engagement hole 261. Even if the bending margin of the protrusion 233 rides on the inner periphery of the engagement hole 261 and the guide sliding contact portion 23 swings, the side edge of the protrusion 233 contacts the left edge or the right edge of the engagement hole 261, and the guide slide The swing of the contact portion 23 is suppressed to a minimum.

  The arc-shaped front edge 231 of this example is formed in an arc shape from the left edge of the guide sliding contact portion 23 to the front edge in the moving direction and the corner extending from the right edge of the guide sliding contact portion 23 to the front edge. The peripheral edge including the front edge is formed as a continuous arc as a whole. Furthermore, the guide sliding contact portion 23 of the present example has a left-right asymmetric arc-shaped peripheral edge in which the radius of the corner portion (right side in FIG. 3) opposite to the right side (outer side) in which the retraction suppression guide 3 is inclined is increased. I have to. This is because when the guide sliding contact portion 23 starts to move along the retraction suppression guide 3, the corner portion collides with the left side surface 31 of the retraction suppression guide 3, thereby reducing the surface pressure due to the corner portion. Therefore, it has the purpose of increasing the area of the corner that instantaneously collides with the side surface 31.

  In addition, the arc-shaped front edge 231 of the present example is smoothly rounded from the sliding contact surface 235 for the purpose of reducing the sliding contact resistance with respect to the upper surface 32 of the receding suppression guide 3 to make the surface smooth. In order to smooth the surface of the arc-shaped leading edge 231, not only polishing the surface but also applying a paint containing a solid lubricant (molybdenum disulfide or a fluororesin powder) having a friction reducing action, for example. It is conceivable to form a lubricating surface. Furthermore, it is desirable that the support hole 232 provided from the sliding contact surface 235 slidably contacting the upper surface 32 of the retraction suppression guide 3 to the mounting surface 236 is sufficiently chamfered.

  The guide sliding contact portion 23 inserts a support bolt 28 from below through a narrow portion of a wide T-shaped support hole 232 in the front, and screwes the support bolt 28 into the upper surface 32 of the retraction restraining guide 3. Supported by When the support member 2 moves backward together with the dash panel 4, a relatively wide portion of the support hole 232 moves toward the support bolt 28, the support of the guide sliding contact portion 23 by the support bolt 28 is released, and the guide sliding contact portion 23. Begins to move along the retraction suppression guide 3. The guide sliding contact portion 23 is fitted into the retraction restraining guide 3 from below, and its movement is restricted to the upper surface 32 and the right and left sides to the pair of side surfaces 31, 31. It is pushed down toward. Thus, in the pedal device of this example, the guide sliding contact portion 23 smoothly moves along the backward movement suppression guide 3, thereby depressing the support member 2 according to the guide sliding contact portion 23 and suppressing the backward movement of the pedal arm 1. To do.

  Next, in the pedal device according to the present invention, the function of depressing the support member 2 and realizing the retraction of the pedal arm 1 will be described. As shown in FIGS. 1 and 2, the pedal device normally projects the support member 2 from the dash panel 4 toward the rear of the vehicle, and steps on the pedal arm 1 pivotally attached to the support member 2. By operating the brake body. In the pedal device of the present invention, the rigidity of the entire arm support portion 22 is ensured by lamination of the bead 24 in the vicinity of the mounting portion and the pedal arm 1, so that the support member 2 is not bent by normal depression of the pedal arm 1. Further, in the pedal device of this example, the arm support portion 22 is supported by being bridged between the dash panel 4 and the deck cross member 5, so that the support member 2 does not wobble. In this way, stable operation of the pedal arm 1 is enabled as a normal state.

  When the vehicle collides and the dash panel 4 moves backward, the support member 2 together with the dash panel 4 and the pedal arm 1 pivotally attached to the support member 2 move backward toward the deck cross member 5. 6, the guide sliding contact portion 23 approaches the upper surface 32 and the left side surface 31 (the lower side surface 31 in FIG. 6) of the retraction restraining guide 3, as seen in FIG. This means that the arcuate front edge 231 collides with the upper surface 32 and the side surface 31. As described above, the guide sliding contact portion 23 is bolted to the upper surface 32 of the retraction suppression guide 3 by the support bolt 28 inserted from the support hole 232. However, the support bolt 28 is supported by the support hole 232 due to the collision of the vehicle. By moving to a wide part of the bolt, the bolt is detached from the bolting and collides with the upper surface 32 and the side surface 31. At this time, the contact pressure of the arcuate front edge 231 against the side surface 31 is low, and the movement of the guide sliding contact portion 3 after the collision is smoothly guided. In addition to this, the surface pressure when the guide sliding contact portion 23 collides with the side surface 31 of the retraction suppressing guide 3 can be suppressed even if a copying surface parallel to the inclined side surface 31 is formed on the arcuate front edge 231.

  When the guide sliding contact portion 23 collides with the upper surface 32 and the side surface 31 of the retraction restraining guide 3, the guide sliding contact portion 23 moves downward along the upper surface 32 and moves rightward while being regulated by the side surface 31. Therefore, the support member 2 according to the guide sliding contact portion 23 is bent downward and retracted while being pushed down. At this time, the support member 2 is sandwiched between the member attachment portion 21 and the attachment portion vicinity bead 24 which is a highly rigid portion, and the virtual bending shaft 27 (see FIG. 1) is set, so that it can be seen in FIG. In addition, it is pushed downward and bent downward with the virtual bending shaft 27 as an axis. Since the pedal arm 1 follows the support member 2 in the left-right direction, the pedal arm 1 is also tilted to the right while being pushed down, and the dash panel 4 is moved backward (the amount of movement in the vehicle front-rear direction). In comparison with this, the rear end of the pedal arm 1, in this example, the amount of retreat of the pedal pad 12 is reduced to suppress retreat.

  Here, the retreat mode of the dash panel 4 is not uniform, and for example, the dash panel 4 may be lifted upward. However, the guide sliding contact portion 23 of this example is bolted to the upper surface 32 of the retraction suppression guide 3 in advance, is regulated by the upper surface 32 of the retraction suppression guide 3, and is further sandwiched between a pair of left and right side surfaces 31,31. (See FIG. 6), the support member 2 is surely pushed downward because it moves without deviating from the retraction control guide 3, so that it is normal that the support member 2 retreats upward. Impossible. Further, since the support member 2 is bent to the right according to the guide sliding contact portion 23 that moves along the backward restraining guide 3 inclined to the right, the pedal arm 1 according to the support member 2 is also inclined to the right. Accordingly, even if the pedal arm is in a posture in which the pedal arm is flipped up about the pedal rotation shaft 13, it is possible to suppress the backward movement to reduce the backward movement amount of the pedal pad 12.

  When the dash panel 4 is pushed downward, the guide sliding contact portion 23 may deviate from the reverse restraining guide 3, but the pedal arm 1 collides with the floor surface of the driver's seat and is less likely to reverse excessively. No problem. Further, when the dash panel 4 is tilted backward in either the left or right direction, as described above, the guide sliding contact portion 23 moves while being restricted in the left and right direction by the retraction restraining guide 3, so that the support member 2 is pushed down. In principle, the bending follows the guide sliding contact portion 23 that moves along the retraction suppression guide 3, and the retraction suppression of the pedal arm 1 can be realized. The retraction suppression guide 3 is a member having an H-shaped cross section with an upper surface 32 sandwiched between a pair of left and right side surfaces 31, 31, and the upper surface 32 is curved downward, so that rigidity is enhanced. Therefore, the guide sliding contact portion 23 that moves moves the guide sliding contact portion 23 along the backward movement suppression guide 3 regardless of the backward movement mode of the dash panel 4 without damaging the backward movement suppression guide 3, and the pedal as designed. It is possible to suppress the backward movement of the arm 1.
