Description

Technical Field

[0001] The invention relates to a pedal device for a vehicle. Background Art

[0002] In the past, there was a pedal device for a vehicle that allows a movable pedal disposed below a door opening to be deployed and retracted in conjunction with the opening and closing action of a sliding door. For example, the pedal device described in Patent Document 1 includes: a guide rail disposed on the lower surface of the movable pedal; and a connecting member having a snap-fitting portion disposed in the guide rail and supported on the sliding door. In addition, in the pedal device of this conventional example, the guide rail has an oblique section that extends obliquely inwardly in the vehicle width direction toward the rear side of the vehicle. Furthermore, the oblique section becomes an engaging section where the snap-fitting portion engages with the inner wall surface of the guide rail by moving the sliding door in an integrated manner along the front-rear direction of the vehicle through the snap-fitting portion of the connecting member. Furthermore, the pedal device is a structure that allows the movable pedal to be moved to an deployed position outwardly in the vehicle width direction and to be moved to a retracted position inwardly in the vehicle width direction in conjunction with the opening and closing action of the sliding door.

[0006] Technical problem to be solved by the invention

[0007] However, in the above-mentioned conventional pedal device, the oblique section of the guide rail extending obliquely inwardly in the vehicle width direction toward the rear side of the vehicle extends to the end of the guide rail on the rear side of the vehicle. Therefore, when the sliding door is opened, before the engaging portion of the connecting member moving in the guide rail reaches the end of the guide rail on the rear side of the vehicle, the movable pedal continues to move outwardly in the vehicle width direction in conjunction with the opening of the sliding door. That is, there is a problem that it takes time to complete the unfolding action of the movable pedal. Summary of the invention

[0008] Technical means for solving technical problems

[0009] The vehicle pedal device of the present invention comprises: a movable pedal supported below a door opening portion provided with a sliding door; a guide rail provided on the movable pedal and extending in the front-rear direction of the vehicle; and a connecting member having a snap-fitting portion arranged in the guide rail and supported by the sliding door, wherein the snap-fitting portion moves in the guide rail based on the opening and closing action of the sliding door moving in the front-rear direction of the vehicle, so that the movable pedal is deployed and stored, and the guide rail comprises: a first oblique section, the first oblique section A section extending obliquely from the closing side end of the guide rail located in the closing direction of the sliding door toward the opening direction of the sliding door in the vehicle width direction outward; a second oblique section, which is closer to the opening direction side than the first oblique section and extends obliquely inward to the vehicle width direction toward the opening direction side; and a parallel section, which is closer to the opening direction side than the second oblique section and extends parallel to the moving trajectory of the engaging portion to the opening side end of the guide rail located in the opening direction of the sliding door.

[0010] According to the above structure, in the parallel section, the engaging portion of the connecting member that moves in the front-rear direction of the vehicle together with the sliding door does not press the side wall portion of the guide rail. As a result, the sliding door reaches the fully open position when the deployment action of the movable pedal stops. That is, the deployment action of the movable pedal can be completed quickly before the sliding door reaches the fully open position. In addition, as a result, when the user places his foot on the movable pedal before the sliding door reaches the fully open position, its stability can also be ensured.

DETAILED DESCRIPTION

[0027] Hereinafter, one embodiment of a vehicle pedal device will be described based on the drawings.

[0028] (Sliding Door)

[0029] like Figure 1 As shown, the vehicle 1 of this embodiment includes a sliding door 4, which is opened along the vehicle front-rear direction ( Figure 1 The door opening 3 provided on the side 2s of the vehicle body 2 is opened and closed by moving the door in the left and right directions.

[0030] In detail, Figure 2As shown, in the vehicle 1 of the present embodiment, a plurality of guide rails 10 extending in the front-rear direction of the vehicle are provided on the side 2s of the vehicle body 2. Specifically, the vehicle 1 of the present embodiment is provided with: a lower rail 11 arranged at the lower edge of the door opening 3, an intermediate rail 12 arranged behind the door opening 3, and an upper rail 13 arranged at the upper edge of the door opening 3. Furthermore, guide roller units 20 that slide along the extending direction of the guide rails 10 are respectively connected to each of these guide rails 10. In addition, in the vehicle 1 of the present embodiment, by supporting the sliding door 4 on the vehicle body 2 via these guide roller units 20, the sliding door 4 of each guide rail 10 extending in the front-rear direction of the vehicle can be opened and closed.

[0031] In addition, if Figure 3 As shown in (a) and (b), each guide rail 10 of the present embodiment has a longitudinal direction end 10f near the front side of the vehicle, extending from the rear side of the vehicle toward the front side toward the vehicle width direction inner side ( Figure 3 That is, in the sliding door 4 of this embodiment having a so-called "rear-opening door" structure that opens toward the rear of the vehicle, the longitudinal end 10f on the front side of the vehicle becomes the end of the side where the sliding door 4 is in a fully closed state. Figure 3 (a) shows the lower rail 11 and the lower roller unit 21. Figure 3 (b) shows the middle rail 12 and the middle roller unit 22, and omits the upper rail 13 and the upper roller unit 23. The sliding door 4 of the present embodiment is configured such that the sliding door 4 is opened and closed in the front-rear direction of the vehicle while being guided by the curved portion 30 provided on each of the guide rails 10 and being displaced in the vehicle width direction.

[0032] That is, the sliding door 4 of the present embodiment is configured such that, when in the fully closed position Pc, its outer surface 4s is substantially flush with the side surface 2s of the vehicle body 2. Furthermore, when opening from such a fully closed position Pc, the sliding door 4 moves toward the rear side of the vehicle while displacing toward the outside in the vehicle width direction. That is, the sliding door 4 has a width direction displacement section Rc for the sliding door 4 to displace toward the vehicle width direction on the fully closed position Pc side of its moving path R. Figure 3 In FIG. 1 , the single-dot chain line indicates the slide door 4 that is opened and closed, and more specifically, indicates the trajectory of the front end portion thereof. The vehicle 1 of the present embodiment is thus configured such that the slide door 4 that is opened and closed does not interfere with the vehicle body 2 .

[0033] In addition, if Figure 2As shown, the vehicle 1 of this embodiment is provided with a power sliding door device 31 that uses a motor 31m as a driving source to open and close the sliding door 4. That is, the occupants of the vehicle 1 are not limited to manual operation, but can also open and close the sliding door 4 by operating a door handle (not shown), an operating switch provided in the vehicle interior, or a portable device. Furthermore, the power sliding door device 31 monitors the driving force required to open and close the sliding door 4, that is, the change in the force required to open and close the sliding door 4, based on the rotation of the motor 31m, the amount of current supplied, etc. And, thereby, it has the function of a pinching detection device 32 that detects pinching occurring in the sliding door 4.

[0034] Specifically, the entrapment detection device 32 of the present embodiment determines that entrapment has occurred in the sliding door 4 when the current amount of the motor 31m increases beyond a predetermined threshold value during the opening and closing drive of the sliding door 4. The power sliding door device 31 of the present embodiment is configured to execute a drive control for releasing or avoiding the entrapment, such as driving the sliding door 4 in the closing drive to reverse to the opening direction, or stopping the sliding door 4 in the opening drive, etc.

[0035] (Pedal device)

[0036] In addition, if Figure 1 and Figure 2 As shown, the vehicle 1 of the present embodiment is provided with a step device 41 that deploys a movable step 40 serving as a footrest below the door opening 3 for use by passengers getting on and off the vehicle 1 .

[0037] In detail, Figures 4 to 10 As shown, in the pedal device 41 of the present embodiment, the movable pedal 40 includes a movable base 42 having a substantially flat plate-like outer shape and a pedal cover 43 fixed to an upper surface 42 sa of the movable base 42 .

[0038] In addition, Figures 4 to 7 In each figure, the left side is the front side of the vehicle, and the right side is the rear side of the vehicle. Figure 4 and Figure 5 In each figure, the lower side is the outer side in the vehicle width direction, and the upper side is the inner side in the vehicle width direction. Figure 6 and Figure 7 In each figure, the upper side is the outer side in the vehicle width direction, and the lower side is the inner side in the vehicle width direction. Figure 8 and Fig. 9 In each figure, the left side is the outer side in the vehicle width direction, and the right side is the inner side in the vehicle width direction.

[0039] Specifically, the movable base 42 of the present embodiment has a pedal portion 44 having a substantially rectangular planar shape with its long side in the vehicle front-rear direction and its short side in the vehicle width direction. Furthermore, the pedal cover 43 also has a substantially rectangular planar shape covering the upper portion of the pedal portion 44. The movable pedal 40 of the present embodiment is structured such that the surface 43s of the pedal cover 43 located on the upper surface 40sa side of the movable pedal 40 forms the pedal surface S on which the user steps.

[0040] In the movable pedal 40 of the present embodiment, the movable base 42 is formed of metal. In addition, the pedal cover 43 is formed of resin. Furthermore, a non-slip concave-convex shape (not shown) is provided on the surface 43s of the pedal cover 43. And the pedal device 41 of the present embodiment is configured so that the user who places his foot on the movable pedal 40 can safely step on the pedal surface S as his pedal area α.

[0041] In addition, the pedal device 41 of the present embodiment includes a pair of support arms 45, which are rotatably connected to the vehicle body 2 and are rotatably connected to the movable pedal 40. Furthermore, each of these support arms 45 rotates in a substantially horizontal direction with the first rotation connection point M1 with respect to the vehicle body 2 as a fulcrum. And, the pedal device 41 of the present embodiment is a structure in which the movable pedal 40 supported by these support arms 45 moves in the vehicle width direction while maintaining a substantially horizontal posture.

[0042] (Support structure of the movable pedal by the support arm)

[0043] In detail, in the pedal device 41 of the present embodiment, each support arm 45 is rotatably connected to a support bracket 46 fixed to the lower surface 2b of the vehicle body 2. Specifically, the support bracket 46 of the present embodiment has a long strip shape extending in the front-rear direction of the vehicle at a position below the door opening 3. Furthermore, the support bracket 46 is fixed to the lower surface 2b of the vehicle body 2 while covering a locking flange 47 protruding toward the lower surface 2b of the vehicle body 2. In addition, the pedal device 41 of the present embodiment is a structure in which the base end 45b of each support arm 45 is connected to the support bracket 46 at a position closer to the outside in the vehicle width direction than the locking flange 47.

[0044] In addition, the movable pedal 40 of the present embodiment has second rotation connection points M2, M2 of each support arm 45 with respect to the movable pedal 40 at positions of the outer end in the vehicle width direction and both ends in the vehicle front-rear direction of the pedal surface S of the pedal area α. In other words, when the vehicle front-rear direction of the movable pedal 40 is set as the "pedal length direction" and the vehicle width direction is set as the "pedal depth direction", the pedal surface S has a substantially rectangular plane shape in which the dimension in the "pedal length direction" is larger than the dimension in the "pedal depth direction". Furthermore, the second rotation connection points M2, M2 of each support arm 45 are set at both end positions in the vehicle front-rear direction of the end in the development direction of the pedal surface S in the rectangular plane shape. That is, in the movable pedal 40 of the present embodiment, the positions of the outer end in the vehicle width direction and both ends in the vehicle front-rear direction of the pedal surface S are the two corners Sc, Sc on the development direction side of the pedal surface S in the substantially rectangular plane shape. The movable pedal 40 of this embodiment is structured such that the support arms 45 , 45 are connected to the pedal portion 44 of the movable base 42 at two corner portions 44 c , 44 c on the deployment direction side. The pedal portion 44 forms the pedal surface S together with the pedal cover 43 .

[0045] Furthermore, the pedal device 41 of the present embodiment supports the movable pedal 40 in a state where each of the support arms 45 is arranged on the upper surface 40sa side of the movable pedal 40. Specifically, in the pedal device 41 of the present embodiment, each of the support arms 45 has a substantially rectangular rod-shaped outer shape that is long and flat. In addition, each of the support arms 45 has a plurality of step portions 48 in the middle portion in the longitudinal direction. Furthermore, each of the support arms 45 of the present embodiment has a crank shape formed by each of the step portions 48, and the height position of the base end portion 45b when viewed from the side (refer to Figure 8 , the height position of the top end portion 45a is arranged above compared with the up-down direction in the figure. In addition, the pedal device 41 of this embodiment is a structure in which the movable pedal 40 supported by these support arms 45 does not interfere with the lower surface 2b of the vehicle body 2 set with the first rotation connection point M1, and is stored below the support bracket 46.

[0046] Specifically, if Figure 4 , Figure 6 and Fig. 9 As shown, in the pedal device 41 of the present embodiment, the movable pedal 40 is arranged at the storage position X0 in a state where the support arms 45 extend in the vehicle front-rear direction along the locking flange 47. In addition, the pedal device 41 of the present embodiment is configured such that, in the storage state of the movable pedal 40, the entirety of the support arms 45 is arranged below the support bracket 46 fixed to the lower surface 2b of the vehicle body 2.

[0047] Furthermore, in this state, the pedal device 41 of the present embodiment is in a state where the top end portion 40a of the movable pedal 40 located at the vehicle width direction end portion in the deployment direction extends in the vehicle front-rear direction along the outer end portion 46a of the support bracket 46. In addition, the pedal device 41 of the present embodiment is thus configured such that, in the stored state, the substantially entire movable pedal 40 is disposed below the vehicle body 2 at a position located inside the vehicle width direction relative to the outer end portion 46a of the support bracket 46.

[0048] In addition, if Figure 5 , Figure 7 and Figure 8 As shown, in the pedal device 41 of the present embodiment, the movable pedal 40 is arranged at the unfolded position X1 in a state where the support arms 45 extend in the vehicle width direction. In addition, the pedal device 41 of the present embodiment is configured such that, in the unfolded state, the substantially entire pedal surface S, except for the vicinity of the base end portion 40b of the movable pedal 40, is arranged outside the vehicle body 2 in the vehicle width direction.

[0049] Furthermore, in the pedal device 41 of the present embodiment, as described above, when the movable pedal 40 is located at the deployed position X1, the support arms 45 are respectively arranged at the two end positions in the vehicle front-rear direction of the rectangular planar pedal surface S. That is, the end positions Sf on the vehicle front side and the end positions Sr on the vehicle rear side of the pedal surface S of the support arms 45 are respectively arranged along the short sides of the rectangular pedal surface S. And, the pedal device 41 of the present embodiment is structured so that the support arms 45 arranged above the movable pedal 40 are unlikely to hinder the occupant using the movable pedal 40.

[0050] In addition, if Figures 4 to 10 As shown in FIG. 1 , the pedal device 41 of the present embodiment includes an arm cover 49 that covers each support arm 45. This protects each support arm 45 disposed above the movable pedal 40 and improves the design thereof.

[0051] In addition, the pedal device 41 of the present embodiment has a stopper member 50 provided at the base end portion 40b of the movable pedal 40. In the pedal device 41 of the present embodiment, the stopper member 50 moves in the vehicle width direction by clamping the locking flange 47 based on the deployment and storage operation of the movable pedal 40 through the cutout 52 provided in the support bracket 46. Furthermore, the stopper member 50 abuts against the flange covering portion 51 of the support bracket 46 covering the locking flange 47 from the outside in the vehicle width direction at the deployment position X1 of the movable pedal 40 (see FIG. 1 ). Figure 7 and Figure 8 ). In addition, the pedal device 41 of the present embodiment can thereby stably hold the movable pedal 40 at the expanded position X1.

[0052] (Guide rail and guide roller unit)

[0053] like Figures 4 to 11 As shown, the pedal device 41 of this embodiment includes a guide rail 60 provided on the lower surface 40sb of the movable pedal 40. In addition, the pedal device 41 includes a guide roller unit 62 as a connecting member 61 engaged with the guide rail 60 in a state supported by the sliding door 4. And the pedal device 41 of this embodiment is a structure that the movable pedal 40 is deployed and stored in conjunction with the opening and closing operation of the sliding door 4 based on the engagement state of the guide rail 60 and the guide roller unit 62.

[0054] In detail, the guide rail 60 of the present embodiment has a rail shape with a cross section that is open downward and is substantially U-shaped. In addition, in the pedal device 41 of the present embodiment, the wire 60 is made of metal. In addition, the wire 60 is fixed to the lower surface 42sb of the movable base 42 that constitutes the lower surface 40sb of the movable pedal 40. In addition, the pedal device 41 of the present embodiment is a structure in which the guide rail 60 provided on the lower surface 40sb of the movable pedal 40 extends in the front-rear direction of the vehicle in this state.

[0055] In addition, in the pedal device 41 of the present embodiment, the guide roller unit 62 includes: a fixing member 63 fixed to the sliding door 4 in a state extending in the vertical direction, and an arm member 64 extending inward in the vehicle width direction in a state connected to the lower end of the fixing member 63. Furthermore, a guide roller 65 rotatably supported by a support shaft 65x protruding upward is provided at the top end of the arm member 64. And the pedal device 41 of the present embodiment is a structure in which the guide rail 60 is connected to the guide roller unit 62 in a state in which the guide roller 65 is arranged in the guide rail 60 having a substantially U-shaped cross section.

[0056] In addition, in the guide roller unit 62 of the present embodiment, the arm member 64 is connected to the fixed member 63 in a rotatable manner. In addition, the guide roller unit 62 of the present embodiment is configured to form a substantially L-shaped fixed member 63 and the arm member 64 when viewed from the side thereof based on the force of the torsion coil spring (not shown). Furthermore, the guide roller unit 62 can make the fixed member 63 and the arm member 64 relatively rotate by overcoming the force of the torsion coil spring by expanding the substantially L-shaped side shape. In addition, the guide roller unit 62 of the present embodiment can easily configure the guide roller 65 provided at the top end of the arm member 64 in the guide rail 60 provided on the lower surface 40sb of the movable pedal 40.

[0057] In the pedal device 41 of the present embodiment, the guide roller 65 constituting the engagement portion 66 of the guide roller unit 62 moves in the guide rail 60 provided on the movable pedal 40 along the extending direction thereof based on the opening and closing operation of the slide door 4 .

[0058] Specifically, in the pedal device 41 of the present embodiment, when the sliding door 4 is in the fully closed position Pc, the guide roller 65 that becomes the engaging portion 66 on the guide roller unit 62 side is arranged at the end 60f on the vehicle front side of the guide rail 60. That is, the guide roller 65 is arranged at the closed side end Ec of the guide rail 60 located in the closing operation direction of the sliding door 4. Furthermore, when the sliding door 4 is in the fully open position Po, the guide roller 65 is arranged at the end 60r on the vehicle rear side of the guide rail 60, that is, the open side end Eo of the guide rail 60 located in the opening operation direction of the sliding door 4.

[0059] That is, in the sliding door 4 of this embodiment having a so-called "rear opening door" structure that opens toward the rear of the vehicle, the front side of the vehicle becomes the closing direction, and the rear side of the vehicle becomes the opening direction. In addition, for the guide rail 60 provided on the movable step 40 that performs the unfolding and folding actions in conjunction with the sliding door 4, the end 60f on the front side of the vehicle becomes the closing side end Ec, and the end 60r on the rear side of the vehicle becomes the opening side end Eo.

[0060] In more detail, the step device 41 of the present embodiment moves the guide roller 65 of the guide roller unit 62 of the slide door 4 toward the vehicle rear side along the extending direction thereof in the guide rail 60 based on the opening action of the slide door 4. Furthermore, at this time, the guide roller 65 engages with the outer wall portion 60a of the guide rail 60 located on the outer side in the vehicle width direction while moving from the end portion 60f on the vehicle front side to the end portion 60r on the vehicle rear side, that is, in the middle of moving from the closed side end portion Ec to the open side end portion Eo of the guide rail 60. Specifically, the guide roller 65 moves toward the vehicle rear side in the guide rail 60 while pressing the outer wall portion 60a toward the outer side in the vehicle width direction by sliding contact with the outer wall portion 60a of the guide rail 60. The step device 41 of the present embodiment is configured such that the movable step 40 having the guide rail 60 is pulled outward in the vehicle width direction and is deployed from the storage position X0 to the deployment position X1 in conjunction with the opening of the slide door 4 .

[0061] In addition, in the pedal device 41 of the present embodiment, based on the closing action of the sliding door 4, the guide roller 65 of the guide roller unit 62 supported by the sliding door 4 moves toward the vehicle front side along the extending direction of the guide rail 60. Furthermore, at this time, the guide roller 65 engages with the inner wall portion 60b of the guide rail 60 located on the inner side in the vehicle width direction while moving from the end portion 60r on the vehicle rear side to the end portion 60f on the vehicle front side, that is, in the middle of moving from the open side end portion Eo to the closed side end portion Ec of the guide rail 60. Specifically, the guide roller 65 moves toward the vehicle front side in the guide rail 60 while pressing the inner wall portion 60b inward in the vehicle width direction by sliding contact with the inner wall portion 60b of the guide rail 60. The pedal device 41 of the present embodiment is configured such that the movable pedal 40 having the guide rail 60 is pressed inward in the vehicle width direction and is retracted from the deployed position X1 to the retracted position X0 in conjunction with the closing operation of the slide door 4 .

[0062] (Shape of guide rail and engagement range of guide roller)

[0063] like Fig.11 As shown, the guide rail 60 of the present embodiment has a first oblique section D1 and a second oblique section D2, which are respectively extended in an oblique state relative to the front-rear direction of the vehicle, which is the pedal length direction of the movable pedal 40. Specifically, the first oblique section D1 is extended obliquely from the end 60f on the front side of the vehicle in the guide rail 60 toward the rear side of the vehicle in the vehicle width direction. In addition, the second oblique section D2 is extended obliquely in the vehicle width direction from the rear side of the vehicle of the guide rail 60 relative to the first oblique section D1. In addition, the guide rail 60 of the present embodiment has a parallel section D3, which extends parallel to the moving track of the guide roller 65 to the end 60r on the rear side of the vehicle on the rear side of the guide rail 60 relative to the second oblique section D2, and the guide roller 65 moves integrally with the sliding door 4.

[0064] In other words, in the guide rail 60 of the present embodiment, the first oblique section D1 extends obliquely from the closing side end Ec of the guide rail 60 located in the closing direction of the sliding door 4 toward the opening direction of the sliding door 4, outward in the vehicle width direction. Furthermore, the second oblique section D2 extends obliquely inward in the vehicle width direction toward the opening direction of the sliding door 4, on the opening direction side of the sliding door 4 compared to the first oblique section D1 in the guide rail 60. And, the parallel section D3 extends substantially straightly parallel to the moving track of the guide roller 65 along the front-rear direction of the vehicle, on the opening direction side of the sliding door 4 compared to the second oblique section D2, to the opening side end Eo of the guide rail 60.

[0065] In addition, in the guide rail 60 of the present embodiment, the oblique angle θ in the first oblique section D1 and the second oblique section D2 relative to the front-rear direction of the vehicle is such that the oblique angle θ2 of the second oblique section D2 is larger than the oblique angle θ1 of the first oblique section D1 (θ1<θ2). Furthermore, the guide rail 60 of the present embodiment has a connection section Dc curved into a substantially trapezoidal shape convexly toward the outside in the vehicle width direction between the first oblique section D1 and the second oblique section D2. And, the pedal device 41 of the present embodiment is thus configured such that the guide roller 65 of the engaging portion 66 on the guide roller unit 62 side smoothly passes through the first oblique section D1 and the second oblique section D2 and moves within the guide rail 60.

[0066] In more detail, Fig.12 As shown, in the pedal device 41 of this embodiment, a portion of the first oblique section D1 on the vehicle rear side, the second oblique section D2, and the connecting section Dc therebetween constitute the engagement section β of the guide roller 65 with respect to the guide rail 60. Fig.12 4 is an operation explanation diagram of the step device 41, which shows the retracted state and the extended state of the movable step 40 in an overlapping manner. Fig.12 The one-dot chain line in denoted a movement trajectory Q of the guide roller 65 that moves integrally with the slide door 4 .

[0067] That is, Figure 3 , Fig.11 and Fig.12 As shown, in the vehicle 1 of the present embodiment, when the sliding door 4 is opened and closed, the sliding door 4 is displaced in the vehicle width direction by moving in the width direction displacement section Rc on the fully closed position Pc side set in the movement path R. Furthermore, the pedal device 41 of the present embodiment is configured such that the guide roller 65 of the guide roller unit 62 that moves integrally with the sliding door 4 at this time moves in the first oblique movement section D1.

[0068] Furthermore, in the pedal device 41 of the present embodiment, the guide roller 65 that moves in the vehicle front-rear direction integrally with the sliding door 4 is engaged with the outer wall portion 60a or the inner wall portion 60b that is the side wall portion of the guide rail 60 based on the vehicle width direction displacement of the sliding door 4. In addition, in the pedal device 41 of the present embodiment, a portion of the vehicle rear side in the first oblique section D1 and a vehicle front side of the connecting section Dc that is continuous with the first oblique section D1 serve as an engagement section β1 of the guide roller 65 based on the vehicle width direction displacement of the sliding door 4.

[0069] In addition, in the pedal device 41 of the present embodiment, the vicinity of the end 60f on the vehicle front side in the first oblique travel section D1 becomes a closed side idle travel section εc in which the guide roller 65 is not engaged with the outer wall section 60a and the inner wall section 60b of the guide rail 60. In addition, the pedal device 41 of the present embodiment does not interfere with the structure of the sliding door 4 in the closed side idle travel section εc set near the closed side end Ec of the guide rail 60.

[0070] In addition, in the pedal device 41 of the present embodiment, when the sliding door 4 is opened and closed, the sliding door 4 moves in the vehicle front-rear direction in a state where the guide roller 65 is arranged in the second oblique section D2 of the guide rail 60. Furthermore, in the pedal device 41 of the present embodiment, at this time, based on the oblique angle θ2 of the second oblique section D2, the guide roller 65 that moves in the vehicle front-rear direction together with the sliding door 4 engages with the outer wall portion 60a or the inner wall portion 60b that is the side wall portion of the guide rail 60. And, in the pedal device 41 of the present embodiment, the second oblique section D2 thus becomes the engagement section β2 of the guide roller 65 based on the vehicle front-rear direction movement of the sliding door 4.

[0071] Specifically, in the pedal device 41 of the present embodiment, when the sliding door 4 is opened, the guide roller 65 that moves toward the rear side of the vehicle together with the sliding door 4 engages with the outer wall portion 60a of the guide rail 60 located at the rear side of the vehicle. Furthermore, when the sliding door 4 is closed, the guide roller 65 that moves toward the front side of the vehicle together with the sliding door 4 engages with the inner wall portion 60b of the guide rail 60 located at the front side of the vehicle. Moreover, the pedal device 41 of the present embodiment is configured so that even when the guide roller 65 is arranged in the second oblique travel section D2, the movable pedal 40 is deployed and retracted in conjunction with the opening and closing of the sliding door 4.

[0072] In addition, in the pedal device 41 of the present embodiment, when the sliding door 4 is opened and closed with the guide roller 65 disposed in the parallel section D3, the guide roller 65 does not press any of the outer wall portion 60a and the inner wall portion 60b of the guide rail 60. In addition, in the pedal device 41 of the present embodiment, the parallel section D3 thus becomes an open side empty section εo including the end portion 60r on the rear side of the vehicle, that is, the open side end portion Eo of the guide rail 60.

[0073] That is, in the pedal device 41 of the present embodiment, when the sliding door 4 is opened, the movable pedal 40 is deployed when the guide roller 65 moving in the guide rail 60 passes through the second oblique section D2 and enters the parallel section D3. In addition, the pedal device 41 of the present embodiment is configured so that the user can use the movable pedal 40 to get on and off the vehicle 1 before the sliding door 4 reaches the fully opened position Po, that is, before the fully opened operation of the sliding door 4 is completed.

[0074] (Extension of the guide rail)

[0075] In addition, if Figures 4 to 10 As shown, in the pedal device 41 of the present embodiment, the guide rail 60 is fixed to the lower surface 40sb of the movable pedal 40 in a state extending toward the vehicle rear side from the end position Sr of the pedal surface S on the vehicle rear side.

[0076] Specifically, in the guide rail 60 of the present embodiment, the portion on the vehicle front side including the first oblique section D1 and the connecting section Dc between the first oblique section D1 and the second oblique section D2 is fixed to the lower surface 44sb of the pedal portion 44 constituting the pedal surface S. In addition, in the pedal device 41 of the present embodiment, the portion on the vehicle rear side including the second oblique section D2 and the parallel section D3 thus becomes the extended portion 70 of the guide rail 60 extending toward the vehicle rear side beyond the end position Sr on the vehicle rear side of the pedal surface S.

[0077] Specifically, in the pedal device 41 of the present embodiment, the movable base 42 constituting the lower surface 40sb of the movable pedal 40 has a rail cover portion 71 extending toward the rear side of the vehicle continuously with the pedal portion 44. In addition, the pedal device 41 of the present embodiment is provided with a resin protective cover 72 covering the upper portion of the rail cover portion 71. Furthermore, the pedal device 41 of the present embodiment is a structure in which the extension portion 70 of the guide rail 60 is fixed to the lower surface 71sb of the rail cover portion 71.

[0078] More specifically, the movable base 42 of the present embodiment has a plurality of reinforcing ribs 73 provided on the lower surface 44sb of the pedal portion 44. The pedal device 41 of the present embodiment is structured so as to improve the strength of the pedal surface S formed by the pedal portion 44 of the movable base 42, that is, the pedal area α of the movable pedal 40 where the user steps.

[0079] On the other hand, the lower surface 71sb of the rail cover portion 71 to which the extension portion 70 of the guide rail 60 is fixed is not provided with a reinforcing structure such as the above-mentioned reinforcing ribs 73. Furthermore, an illustration (omitted from the illustration) indicating that it is not recommended for a user to rest on the portion covered by the protective cover 72 is given to the surface 72s of the protective cover 72 covering the rail cover portion 71. In addition, in the pedal device 41 of the present embodiment, the upper portion of the rail cover portion 71 to which the extension portion 70 of the guide rail 60 is fixed is thus set as a non-pedal area γ.

[0080] (effect)

[0081] In the pedal device 41 of the present embodiment, the second oblique section D2 of the guide rail 60 becomes the engagement section β2 of the guide roller 65 based on the vehicle front-rear direction movement of the sliding door 4. Furthermore, the opening and closing action of the sliding door 4 is consistent with the unfolding and retracting action of the movable pedal 40 by the second oblique section D2 obliquely moving inward in the vehicle width direction toward the rear side of the vehicle. That is, the movable pedal 40 is unfolded in conjunction with the opening action of the sliding door 4 that moves toward the rear side of the vehicle as a whole with the guide roller 65 and the sliding door 4. In addition, the movable pedal 40 is unfolded in conjunction with the closing action of the sliding door 4 that moves toward the front side of the vehicle as a whole with the guide roller 65 and the sliding door 4.

[0082] In addition, by performing the unfolding and stowing action of the movable step 40 based on the vehicle front-rear movement of the sliding door 4, even if the sliding door 4 has a small displacement in the vehicle width direction near the fully closed position Pc, the movement amount of the movable step 40 in the vehicle width direction is increased. Furthermore, the parallel section D3 of the guide rail 60 including the end 60r on the vehicle rear side as the open side end Eo becomes the open side empty section εo that is not engaged with the guide roller 65. And, thereby, the sliding door 4 reaches the fully open position Po in the state where the unfolding action of the movable step 40 is stopped. That is, before the sliding door 4 reaches the fully open position Po, the unfolding action of the movable step 40 is completed.

[0083] Next, the effects of this embodiment will be described.

[0084] (1) The pedal device 41 includes a movable pedal 40 supported below the door opening 3 where the sliding door 4 is provided, and a guide rail 60 provided on the movable pedal 40 and extending in the front-rear direction of the vehicle. The pedal device 41 also includes a guide roller unit 62 as a connecting member 61, the guide roller unit 62 having a guide roller 65 as an engaging portion 66 disposed in the guide rail 60 and supported by the sliding door 4. The pedal device 41 moves in the guide rail 60 via the guide roller 65 based on the opening and closing action of the sliding door 4 moving in the front-rear direction of the vehicle, and the movable pedal 40 is deployed and retracted.

[0085] In addition, the guide rail 60 has a first oblique section D1, which extends obliquely outward in the vehicle width direction from an end 60f on the vehicle front side, which is a closed side end Ec, toward the vehicle rear side, which is the opening direction of the sliding door 4. Furthermore, the guide rail 60 has a second oblique section D2, which extends obliquely inward in the vehicle width direction toward the vehicle rear side, which is closer to the vehicle rear side than the first oblique section D1. In addition, the guide rail 60 has a parallel section D3, which extends parallel to the movement trajectory Q of the guide roller 65, which is closer to the vehicle rear side than the second oblique section D2, to an end 60r on the vehicle rear side, which is an open side end Eo.

[0086] According to the above structure, by providing the second oblique movement section D2, when the sliding door 4 moves in the vehicle front-rear direction, the guide roller 65 that moves integrally with the sliding door 4 can be engaged with and pressed against the side wall portion according to the moving direction. And, thereby, the movable step 40 can be deployed and retracted based on the vehicle front-rear movement of the sliding door 4. As a result, even when applied to a sliding door 4 with a small displacement in the vehicle width direction near the fully closed position Pc, a larger movement amount in the vehicle width direction, that is, an deployment amount, can be set for the movable step 40.

[0087] In addition, in the parallel section D3, the guide roller 65 that moves in the vehicle front-rear direction integrally with the sliding door 4 does not press the side wall portion of the guide rail 60. As a result, the sliding door 4 reaches the fully opened position Po in a state where the deployment action of the movable step 40 is stopped. That is, the deployment action of the movable step 40 can be quickly completed before the sliding door 4 reaches the fully opened position Po. And, thus, even if the user places his foot on the movable step 40 before the sliding door 4 reaches the fully opened position Po, its stability can be ensured.

[0088] Furthermore, by providing the first oblique movement section D1, when the sliding door 4 is opened and closed near the fully closed position Pc where the width direction displacement section Rc is set, the guide roller 65 can be prevented from engaging with the outer wall portion 60a or the inner wall portion 60b of the guide rail 60. In addition, when the sliding door 4 moves near the fully closed position Pc, the pedal device 41 does not interfere, thereby ensuring smooth opening and closing of the sliding door 4. As a result, for example, erroneous operation of the pinching detection device 32 that detects pinching occurring in the sliding door 4 can be avoided.

[0089] (2) In the second oblique travel section D2 , the oblique travel angle θ of the guide rail 60 with respect to the vehicle front-rear direction is larger than that in the first oblique travel section D1 ( θ1 < θ2 ).

[0090] According to the above configuration, the deployment operation of the movable step 40 can be completed at an earlier stage before the sliding door 4 reaches the fully opened position Po.

[0091] (3) The guide rail 60 includes the extending portion 70 extending toward the vehicle rear side beyond the end position Sr on the vehicle rear side of the step surface S of the movable step 40 , and is fixed to the lower surface 40sb of the movable step 40 .

[0092] That is, in order to ensure stable unfolding and storage of the movable pedal 40 in conjunction with the opening and closing of the sliding door 4, it is preferred that the guide rail 60 has a sufficient length corresponding to the moving distance of the sliding door 4 in the vehicle front-rear direction. However, the pedal surface S on which the movable pedal 40 is formed does not necessarily need such a large dimension in the vehicle front-rear direction, that is, the pedal length. In addition, in the vehicle 1, there are many situations in which the storage space for the movable pedal 40 is limited. Therefore, in the case of a large pedal surface S covering the entirety of the guide rail 60, it is expected that it will be difficult to properly store the movable pedal 40 due to the limitations of the vehicle.

[0093] In this regard, according to the above-described configuration, the movable pedal 40 can be appropriately stored while ensuring stable operation of the movable pedal 40. In addition, the convenience for the user and the mountability on the vehicle 1 can be improved thereby.

[0094] (4) The pedal device 41 has a first rotation connection point M1 with respect to the vehicle body 2 and a second rotation connection point M2 with respect to the movable pedal 40, and is provided with a pair of support arms 45 for supporting the movable pedal 40. Furthermore, each of the support arms 45 has the second rotation connection point M2 at a position on the pedal surface S of the movable pedal 40 that is the outer end in the vehicle width direction and at both ends in the vehicle front-rear direction, and is arranged on the upper surface 40sa side of the movable pedal 40.

[0095] According to the above structure, in the state where each support arm 45 forms a parallel link, the movable pedal 40 supported by it can be stably deployed and stored. In addition, by providing the second rotation connection point M2 of each support arm 45 with respect to the movable pedal 40 at the position of the outer end in the vehicle width direction in the pedal surface S, the protrusion amount to the outer side in the vehicle width direction can be minimized when the movable pedal 40 is stored. Furthermore, by arranging each support arm 45 on the upper surface 40sa side of the movable pedal 40, these support arms 45 can be rotated in a relatively short and simple shape while avoiding interference between the movable pedal 40 and the vehicle body 2. And, thereby, it is possible to ensure high support rigidity of each support arm 45 and stably deploy and store the movable pedal 40.

[0096] In particular, by utilizing its relatively short and simple shape, the first rotation connection point M1 of each support arm 45 with respect to the vehicle body 2 can be set at a position close to the end portion of the lower surface 2b of the vehicle body 2 that is closer to the outer side in the vehicle width direction, for example, at a position that is closer to the outer side in the vehicle width direction than the locking flange 47. And thereby, it is possible to ensure excellent mounting performance on the vehicle 1.

[0097] In addition, by providing the second rotation connection points M2 of the support arms 45 at the positions of the two ends of the pedal surface S in the vehicle front-rear direction, when the movable pedal 40 is in the deployed position X1, the support arms 45 are arranged along the two end positions of the pedal surface S in the vehicle front-rear direction. That is, by arranging the support arms 45 at the end positions Sf on the vehicle front side and the end positions Sr on the vehicle rear side of the pedal surface S, the support arms 45 arranged above the movable pedal 40 in the deployed position X1 are less likely to hinder the user. Furthermore, the effect of indicating the pedal surface S as the pedal area α where the user should place his foot can be expected. And, thereby, while ensuring excellent convenience, the movable pedal 40 can be supported more stably in the deployed position X1.

[0098] In addition, the above-mentioned embodiment can be modified and implemented as follows. The above-mentioned embodiment and the following modified examples can be combined and implemented with each other within the range that there is no technical contradiction.

[0099] In the above embodiment, the pedal device 41 is embodied as a so-called "rear-opening door" type sliding door 4 that opens toward the rear side of the vehicle, but it can also be applied to a so-called "front-opening door" type sliding door 4 that opens toward the front side of the vehicle. In addition, when applied to such a "front-opening door" type sliding door 4, the rear side of the vehicle is the closing direction, and the front side of the vehicle is the opening direction. In addition, regarding the guide rail 60 provided on the movable pedal 40 that performs the unfolding and storage actions in conjunction with the sliding door 4, the end 60r on the rear side of the vehicle is the closing side end Ec, and the end 60f on the front side of the vehicle is the opening side end Eo (not shown).

[0100] In the above-described embodiment, the sliding door 4 is opened and closed by being driven by the power sliding door device 31 , but the present invention may also be applied to a sliding door 4 that does not include such a power sliding door device 31 .

[0101] In the above embodiment, the guide rail 60 has a connection section Dc that is curved in a substantially trapezoidal shape and convexly outward in the vehicle width direction between the first oblique section D1 and the second oblique section D2. However, the present invention is not limited thereto, and the connection section Dc may also be substantially arc-shaped. Furthermore, the portion that becomes the connection section Dc may have a second parallel section that extends parallel to the moving track of the guide roller 65 that is the engaging portion 66.

[0102] In the above embodiment, there is a first rotation connection point M1 with respect to the vehicle body 2 and a second rotation connection point M2 with respect to the movable pedal 40, and a pair of support arms 45 for supporting the movable pedal 40 are provided. Furthermore, each of these support arms 45 has the second rotation connection point M2 at a position that is an outer end in the vehicle width direction and both ends in the vehicle front-rear direction in the pedal surface S of the movable pedal 40, and is arranged on the upper surface 40sa side of the movable pedal 40.

[0103] However, this is not limited to the above, and the second rotation connection point M2 of each support arm 45 relative to the movable pedal 40 may be arbitrarily changed. The first rotation connection point M1 of each support arm 45 relative to the vehicle body 2 may be arbitrarily changed. In addition, the shape of each support arm 45 may be arbitrarily changed. Furthermore, the support arm 45 may be arranged on the lower surface 40sb side of the movable pedal 40. Furthermore, the number of support arms 45 may be arbitrarily changed.

[0104] For example, the movable pedal 40 may be supported by one or more than three support arms 45. In addition, for example, a structure may be provided in which the first rotation connection point M1 of the support arm 45 relative to the vehicle body 2 is provided at a position further inward in the vehicle width direction than the locking flange 47. Furthermore, the present invention may be applied to a structure using a support structure other than a rotation arm such as the support arm 45 in the present embodiment, such as a rail and a slider.

[0105] In the above-mentioned embodiment, the guide roller unit 62 as the connecting member 61 has a fixed member 63 relative to the sliding door 4, an arm member 64 extending from the fixed member 63 inward in the vehicle width direction, and a guide roller 65 axially supported at the top end of the arm member 64. Then, the guide roller 65 is engaged with the guide rail 60 as an engaging portion 66. However, this is not limited to this, and the structure of the connecting member 61 can also be changed arbitrarily. For example, the engaging portion 66 relative to the guide rail 60 does not have to be a rotating body like the guide roller 65. It can also have an axis shape or a slider shape that engages in a manner of sliding contact with the inner wall portion of the guide rail 60. In addition, the supporting structure of the engaging portion 66 in the connecting member 61 can also be changed arbitrarily.

[0106] In the above-mentioned embodiment, the movable base 42 constituting the lower surface 40sb of the movable pedal 40 has a rail cover portion 71 extending continuously toward the rear side of the vehicle together with the pedal portion 44 constituting the pedal surface S together with the pedal cover 43. And the rail cover portion 71 and the protective cover 72 covering the upper part thereof function as a cover member of the extended portion 70 set on the guide rail 60. However, this is not limited to this, and the cover member of the extended portion 70 may also be arbitrarily changed. For example, the portion corresponding to the rail cover portion 71 may also be formed separately from the pedal portion 44 of the movable base 42. In addition, it may also be a structure in which a cover member integrating the rail cover portion 71 and the protective cover 72 is assembled above the extended portion 70. In addition, it may also be a structure without such a cover member covering the upper part of the extended portion 70.

[0107] In addition, in the above-mentioned embodiment, the portion extending toward the vehicle rear side beyond the end position Sr on the vehicle rear side of the step surface S of the movable step 40 is used as the extended portion 70 of the guide rail 60. However, the present invention is not limited thereto, and the portion extending toward the vehicle front side beyond the end position Sf on the vehicle front side of the step surface S may be used as the extended portion 70 of the guide rail 60. Furthermore, a structure may be adopted in which the portion extending toward the vehicle rear side beyond the end position Sr on the vehicle rear side of the step surface S and the portion extending toward the vehicle front side beyond the end position Sf on the vehicle front side of the step surface S are used as the extended portion 70 of the guide rail 60, respectively.

[0108] Next, technical ideas that can be grasped from the above-mentioned embodiment and modified examples are described.

[0109] (a) In the second oblique movement section, the guide rail has a greater oblique movement angle with respect to the front-rear direction of the vehicle than in the first oblique movement section. Thus, the movable step can be deployed at an earlier stage before the sliding door reaches the fully open position.

[0110] (b) The guide rail has an extending portion extending beyond an end position of a step surface of the movable step in the vehicle front-rear direction, and is fixed to a lower surface of the movable step.

[0111] That is, in order to ensure stable deployment and storage of the movable pedal in conjunction with the opening and closing of the sliding door, it is preferred that the guide rail has a sufficient length corresponding to the moving distance of the sliding door in the front-rear direction of the vehicle. However, for the pedal surface formed with the movable pedal, such a large dimension in the front-rear direction of the vehicle is not necessarily required. In addition, in the vehicle, there are many restrictions when setting the storage space of the movable pedal. Therefore, in the case of a large pedal surface covering the entirety of the guide rail, it is expected to be difficult to properly store the movable pedal due to its vehicle-mounted limitations.

[0112] In this regard, according to the above-mentioned structure, the movable pedal can be appropriately stored while ensuring stable movement of the movable pedal, thereby improving user convenience and mountability on the vehicle 1.

[0113] (c) having a pair of support arms, the pair of support arms having a first rotation connection point relative to the vehicle body and a second rotation connection point relative to the movable pedal, and supporting the movable pedal, and each of the support arms having the second rotation connection point at a position on the pedal surface of the movable pedal that is an outer end in the vehicle width direction and at both ends in the vehicle front-rear direction, and being arranged on the upper surface side of the movable pedal.

[0114] According to the above structure, when each support arm forms a parallel link, the movable pedal supported by it can be stably unfolded and retracted. In addition, by providing a second rotation connection point of each support arm relative to the movable pedal at a position on the pedal surface that becomes the outer end in the vehicle width direction, when the movable pedal is retracted, the protrusion to the outside in the vehicle width direction can be minimized. Furthermore, by arranging each support arm on the upper surface side of the movable pedal, it is possible to rotate these support arms in a relatively short and simple shape while avoiding interference between the movable pedal and the vehicle body. And, thereby, it is possible to ensure high support rigidity of each support arm, and stably unfold and retract the movable pedal.

[0115] In particular, by utilizing its relatively short and simple shape, the first rotation connection point of each support arm relative to the vehicle body can be set at a position of the lower surface of the vehicle body close to the end portion in the vehicle width direction outer side, for example, a position in the vehicle width direction outer side relative to the locking flange. And thereby, it is possible to ensure excellent mounting performance on the vehicle.

[0116] In addition, by providing the second rotation connection points of each support arm at the positions of the two ends of the pedal surface in the front-rear direction of the vehicle, when the movable pedal is in the deployed position, each support arm is arranged along the two end positions of the pedal surface in the front-rear direction of the vehicle. That is, by arranging these support arms at the end positions of the front side of the vehicle and the end positions of the rear side of the vehicle in the pedal surface, each support arm arranged above the movable pedal in its deployed position is less likely to hinder the user. Furthermore, it can be expected that these support arms will indicate to the user the pedal surface as the pedal area where the foot should rest. And, thereby, while ensuring excellent convenience, the movable pedal can be supported in the deployed position more stably.

[0117] (d) The connecting section between the first oblique section and the second oblique section is a second parallel section extending parallel to the movement trajectory of the engaging portion.

[0118] (e) A cover member is provided to cover the upper side of the extension portion. Thus, by protecting the extension portion, it is possible to ensure smooth deployment and opening and closing of the movable step caused by the engagement portion of the connection member moving along the guide rail.
