Description

Technical Field

[0001] The present disclosure relates to an operating pedal device for a vehicle. Background Art

[0002] A vehicle such as an automobile is provided with a vehicle operating pedal device such as a brake device, a clutch device, etc. For example, in Patent Document 1, Fig. 20 1, a brake pedal device 100 of a conventional brake device is disclosed. As a basic structure, the brake pedal device 100 includes a pedal bracket 101 and a brake pedal 103. The pedal bracket 101 is fixed to an instrument panel 102. The brake pedal 103 includes a brake arm 104, and the brake arm 104 is rotatably supported on the pedal bracket 101. In addition, the brake pedal device 100 drives a push rod 106, which is an input shaft of a brake booster 105, in conjunction with the rotation of the brake arm 104, so that the brake booster 105 is operated.

[0003] The brake pedal device 100 further includes a mechanism (reverse movement suppression mechanism) for suppressing the brake pedal 103 from moving backward (hereinafter referred to as "reverse movement") when an impact force acts on the vehicle body 108 from the front due to a vehicle collision. The reverse movement suppression mechanism includes a connecting arm 107, a rotating arm 110, and a rivet shaft 116.

[0004] The connecting arm 107 is rotatably supported on the pedal bracket 101. The connecting arm 107 connects the push rod 106 and the brake arm 104. The rotating arm 110 has a first link 111 and a second link 113. The first link 111 is rotatably supported on the connecting arm 107 via a first connecting shaft 112, and the second link 113 is rotatably supported on the connecting arm 107 via a second connecting shaft 114. The first link 111 and the second link 113 are connected via a third connecting shaft 115. A rivet shaft 116 is inserted through the first link 111, the second link 113, and the connecting arm 107.

[0005] According to the above-mentioned brake pedal device 100, when the vehicle collides, the instrument panel 102 moves rearward with the brake pedal device 100. The first link 111 abuts against the instrument panel reinforcement 117 as a vehicle body component, and the instrument panel reinforcement 117 is arranged to be closer to the rear than the instrument panel 102. Through this abutment, when a load above a threshold value is applied from the instrument panel reinforcement 117 to the first link 111, the rivet shaft 116 is broken due to shearing or the like. The first link 111 and the second link 113 can both rotate relative to the connecting arm 107. The rotation of the first link 111 is transmitted to the second link 113 via the third connecting shaft 115. When the second link 113 rotates relative to the connecting arm 107, it pushes the push rod 106 from below. When the push rod 106 is bent by this push, the brake pedal 103 moves forward.

[0007] However, in the conventional brake pedal device 100 in which the push rod 106 is connected to the connecting arm 107, if the connecting arm 107 is deformed or the connection between the push rod 106 and the connecting arm 107 is loosened, the following problems may occur when the vehicle is not in a collision. That is, it is difficult to push the push rod 106 when stepping on the brake pedal 103, and it is difficult to perform a stable stepping operation.

[0008] The above-mentioned problem is not limited to the brake pedal device 100, and the same problem may occur in any vehicle operating pedal device that drives an input shaft of a device for transmitting a pedaling force of an operating pedal. Solutions for solving problems

[0009] A vehicle operating pedal device according to one embodiment of the present disclosure is suitable for a vehicle having a partition wall and a vehicle body component, wherein the partition wall divides a vehicle compartment from a portion of the vehicle compartment that is closer to the front than the vehicle compartment in the vehicle body, and the vehicle body component is arranged closer to the rear than the partition wall. The operating pedal device has a pedal bracket and an operating pedal, wherein the pedal bracket is fixed to the partition wall, and the operating pedal has a pedal arm that is rotatably supported on the pedal bracket. An input shaft of a device for transmitting a pedaling force of the operating pedal is connected to the pedal arm. The input shaft is configured to be driven in conjunction with the rotation of the pedal arm. The operating pedal device also has a rotating rod and a safety portion. The rotating rod has an abutting portion and a pushing portion, and is supported on the pedal arm through a rotating shaft portion. The rotating rod is configured so that when the abutting portion abuts against the vehicle body component in a collision with the vehicle, a load greater than a threshold value is received, so that the rotating rod rotates around the rotating shaft portion, so that the pushing portion pushes the input shaft in a direction intersecting with the axis of the input shaft. The safety portion is configured to fix the rotating lever to the pedal arm when the load from the vehicle body component received by the rotating lever is less than the threshold value, and to break to release the fixation when the load is greater than the threshold value.

[0011] Below, refer to Figures 1 to 11 A brake pedal device as an example of a vehicle operation pedal device will be described. In the following description, the vehicle 10 is described as moving forward and backward. The vertical direction refers to the vertical direction of the vehicle 10, and the horizontal direction refers to the vehicle width direction and coincides with the horizontal direction when the vehicle 10 moves forward.

[0012] like Figure 1 As shown, in the vehicle 10, the vehicle compartment 11 is divided from a portion of the vehicle body 15 that is closer to the front than the vehicle compartment 11, such as the engine compartment, by an instrument panel 12 as a partition wall. An instrument panel reinforcement 13 and a collision bracket 14 that are vehicle body components are arranged at a position closer to the rear than the instrument panel 12. The instrument panel reinforcement 13 is a tubular member extending in the left-right direction for reinforcing the vehicle body 15. The collision bracket 14 is fixed to the front lower portion of the instrument panel reinforcement 13.

[0013] <Basic Structure of Braking Device 20> The vehicle 10 is provided with a brake device 20 for applying a braking force to wheels (not shown). The brake device 20 includes a brake pedal device 21 and a brake booster 40 as a boosting device.

[0014] like Figure 1 to Figure 3 As shown, the brake pedal device 21 includes a pedal bracket 22 and an operating pedal 25. The pedal bracket 22 is directly fixed to the instrument panel 12 or fixed to another component mounted on the instrument panel 12. The pedal bracket 22 includes a pair of side plates 23 arranged in parallel in a state separated from each other in the left-right direction. An operating shaft 24 is straddled on the two side plates 23.

[0015] The operating pedal 25 includes a pedal arm 26 and a pedal portion 28. The pedal arm 26 is formed of a metal plate and is formed to be elongated in the vertical direction compared to the front-rear direction. The pedal arm 26 is rotatably supported on the pedal bracket 22 at its upper end portion through the operating shaft portion 24. The pedal portion 28 is a portion for the driver to step on, and is fixed to the lower end portion of the pedal arm 26.

[0016] like Figure 1As shown, the brake booster 40 (boosting device) is an example of a device for transmitting the pedal force of the operating pedal 25. The brake booster 40 is used to reduce the pedal force of the operating pedal 25, and has a plunger 41 and an input shaft 42. The plunger 41 can move in the front-rear direction. The input shaft 42 has a push rod 43 and a clamp 44. The axis L1 of the push rod 43 extending in the front-rear direction is consistent with the axis of the input shaft 42. The push rod 43 has a ball portion 43a that engages with the plunger 41 at its front end portion. The push rod 43 can swing relative to the plunger 41 with the ball portion 43a as a fulcrum. As shown in FIG. Figure 4 As shown in FIG. 1 , the clamp 44 has a pair of side plates 45 and a connecting plate 46 and is U-shaped when viewed from above. The pair of side plates 45 are arranged to be parallel to each other in a state of being separated from each other in the left-right direction, and the connecting plate 46 connects the front ends of the two side plates 45 to each other. A connecting pin 47 is straddled at the rear ends of the two side plates 45. The center portion of the connecting plate 46 in the left-right direction is fixed to the rear end of the push rod 43. This fixing is achieved by a fastening member 48 such as a bolt or a nut. Through this fixing, the push rod 43 and the clamp 44 are integrated.

[0017] In addition, if Figure 1 As shown, in the brake pedal device 21 , the brake booster 40 is operated by driving (pushing) the input shaft 42 in conjunction with the rotation of the pedal arm 26 . The brake pedal device 21 also has a retraction prevention mechanism 50, and the retraction prevention mechanism 50 has a rotating rod 51, a rotating shaft portion 60, and a safety portion 80. The axis L2 of the rotating shaft portion 60 and the axis L3 of the safety portion 80 both extend in the left-right direction. In the present embodiment, as the pedal arm 26, a member that is the same as the pedal arm in a brake pedal device (not shown) that does not have the retraction prevention mechanism 50, or has the same outer shape as the pedal arm is used. The pedal arm is not significantly changed in shape in order to attach the retraction prevention mechanism 50.

[0018] <Rotation lever 51> like Figure 2 and Figure 6 As shown, the rotating rod 51 is made of a metal material such as iron and is formed of a plate having a thickness thinner than that of the pedal arm 26. The left-right direction, which is the direction along the axis L2 of the rotating shaft portion 60, is the thickness direction of the rotating rod 51. The skeleton portion of the rotating rod 51 is a plate-shaped rod body portion 52 that is longer in the up-down direction than in the front-back direction. Figure 1 and Figure 2 As shown, the upper end of the rod body 52 is located at a height position equivalent to the middle portion of the collision bracket 14 in the vertical direction. The front lower end of the rod body 52 is located below the above-mentioned operating shaft 24. The rod body 52 is arranged to overlap with one side in the thickness direction of the pedal arm 26, in this embodiment, the left side, but it can also be arranged to overlap with the right side.

[0019] The rotating lever 51 further includes a contact portion 53 and a pressing portion 54. The contact portion 53 is formed on the rear surface of the upper end portion of the lever body portion 52, that is, at a position in front of the collision bracket 14.

[0020] like Figure 2 and Figure 4 As shown in FIG. 1 , the push portion 54 protrudes from the front edge of the front lower end of the rod body 52 toward the pedal arm 26 in the thickness direction of the rod body 52, here, on the right side. The push portion 54 is formed in a plate shape extending in the vertical direction with a size larger than the thickness of the rod body 52 in the left-right direction. In the present embodiment, the left-right size of the push portion 54 is set to a size close to the interval between the two side plates 45 of the clamp 44. The push portion 54 is formed integrally with the rod body 52 by bending the front lower end of the plate used to form the rod body 52.

[0021] like Figure 1 and Figure 4 As shown, the pressing portion 54 is disposed below the instrument panel reinforcement 13 and the collision bracket 14 and above the input shaft 42. The middle portion of the pressing portion 54 in the left-right direction is disposed above the axis L1.

[0022] The rotating lever 51 is supported by the pedal arm 26 via a rotating shaft portion 60 at a rear lower end portion of the lever body portion 52 which is located at a position different from the contact portion 53 and the pressing portion 54 . When the following condition is satisfied, the rotating lever 51 rotates around the rotating shaft portion 60 so that the pressing portion 54 presses the connecting plate portion 46 in a direction intersecting the axis L1, which is orthogonal in this embodiment. The condition is that when the abutting portion 53 abuts against the collision bracket 14 in the event of a collision of the vehicle 10, the rotating lever 51 receives a load greater than a predetermined threshold value from the collision bracket 14.

[0023] like Figure 6 As shown, in order to support the rotating lever 51 to the pedal arm 26 via the rotating shaft portion 60, an arm hole 31 is formed at a position behind the input shaft 42 of the pedal arm 26. A rod hole 55 having a larger hole diameter than the arm hole 31 is formed at a position behind the input shaft 42 of the lever body portion 52.

[0024] <Rotation shaft portion 60> The rotating shaft portion 60 is a stepped pin made of metal having a small diameter portion 61, a large diameter portion 62, and a flange portion 63. The small diameter portion 61 is fitted into the arm hole 31. The end of the small diameter portion 61 away from the rod body portion 52 (right side) is exposed from the arm hole 31. At the exposed end, a rivet portion 64 is formed by riveting the end to form a rivet portion 64 that is larger in radial direction than the small diameter portion 61. The large diameter portion 62 is in a large diameter shape that is larger in radial direction than the small diameter portion 61 and is fitted into the rod hole 55. The small diameter portion 61 is fixed to the pedal arm 26 by sandwiching the pedal arm 26 from both sides by the large diameter portion 62 and the rivet portion 64. The end of the large diameter portion 62 away from the pedal arm 26 (left side) is exposed from the rod hole 55. The flange portion 63 is formed at the above-mentioned end of the large diameter portion 62 and is in a large diameter shape that is larger in radial direction than the rod hole 55. The flange portion 63 is separated from the rod body portion 52 by a gap G1 in a direction away from the pedal arm 26 (left side). The rotation shaft portion 60 has a shear strength such that the rotation lever 51 does not break even when receiving a load from the collision bracket 14 when the vehicle 10 collides.

[0025] <Security Department 80> The safety portion 80 has the same function as what is generally called a shear pin. In more detail, when the load borne by the rotating rod 51 from the collision bracket 14 is less than the above threshold, the safety portion 80 fixes the rotating rod 51 to the pedal arm 26. When the load borne by the rotating rod 51 is above the above threshold, the safety portion 80 breaks and the above fixation is released. In addition, the above fixation achieved by the safety portion 80 refers to a state in which the rotating rod 51 is restricted from rotating relative to the pedal arm 26 with the rotating shaft portion 60 as the center. This fixation includes not only a state in which the rotating rod 51 cannot move relative to the pedal arm 26 in the thickness direction of the rotating rod 51, but also a state in which it can move.

[0026] In order to make the safety part 80 play the above function, the arm hole 32 is formed by stamping at the upper and oblique front position of the pedal arm 26 relative to the arm hole 31. The rod hole 56 with a smaller hole diameter than the arm hole 32 is formed at the upper and oblique front position of the rod body 52 relative to the rod hole 55.

[0027] The safety portion 80 is a stepped metal pin having a large diameter portion 81, a flange portion 82, and a small diameter portion 83. The large diameter portion 81 is fitted into the arm hole 32. The end of the large diameter portion 81 away from the rod body portion 52 (right side) is exposed from the arm hole 32. The flange portion 82 is formed in a large diameter shape at the above-mentioned end of the large diameter portion 81, which is larger in radial direction than the arm hole 32.

[0028] The small diameter portion 83 is in a radially smaller diameter shape than the large diameter portion 81 and is fitted into the rod hole 56. The small diameter portion 83 is formed to have a smaller diameter in the radial direction than the small diameter portion 61 of the shaft portion 60. By setting the diameter to the above, the shear strength of the safety portion 80 is smaller than the shear strength of the shaft portion 60. The end of the small diameter portion 83 away from the pedal arm 26 (left side) is exposed from the rod hole 56. At the exposed end, a rivet portion 84 is formed by riveting the end so as to be larger in the radial direction than the small diameter portion 83.

[0029] Here, from the viewpoint of breaking the safety portion 80 when the vehicle 10 collides, it is preferable to use a straight pin with a smaller diameter for the large diameter portion 81 as well as the small diameter portion 83. For this reason, the diameter of the arm hole 32 is made as small as the diameter of the rod hole 56. Nevertheless, the reason why a pin with a larger diameter than the rod hole 56 and a step is used is as follows. As described above, the plate thickness of the pedal arm 26 is larger than the plate thickness of the rod body 52. ​​When forming an arm hole 32 with the same small diameter as the rod hole 56 on the pedal arm 26 with a large plate thickness, machining is required (forming a pre-hole, machining the diameter, and chamfering), and the cost required for formation becomes high.

[0030] In contrast, the arm hole 32 can be formed by punching at a lower cost than machining, which helps reduce the cost of the entire fixing structure of the rotating lever 51 implemented by the safety portion 80 .

[0031] Furthermore, in this embodiment, if Figure 1 and Figure 4 As shown in FIG. 1 , the input shaft 42 of the brake booster 40 is connected to the pedal arm 26. More specifically, in the present embodiment, a clamp hole 27 is formed in a portion of the front portion of the pedal arm 26, in a position in front of the rotation shaft portion 60 (arm hole 31). The clamp hole 27 of the pedal arm 26 and its surrounding portion are arranged between the two side plates 45 of the clamp 44. In addition, as described above, the connecting pin 47 spanning the two side plates 45 is inserted through the above-mentioned clamp hole 27. The push rod 43 is connected to the pedal arm 26 via the clamp 44 and the connecting pin 47.

[0032] Next, the operation of this embodiment having the above-mentioned structure will be described. <When the vehicle 10 does not collide> Figure 1 The brake pedal device 21 is shown when the driver does not step on the operating pedal 25 when the vehicle 10 is not in a collision state. The contact portion 53 of the rotating rod 51 is separated forward from the collision bracket 14. The safety portion 80 fixes the rotating rod 51 to the pedal arm 26 together with the rotating shaft portion 60 while positioning the rotating rod 51 in the rotation direction around the rotating shaft portion 60. The pressing portion 54 is separated upward from the connecting plate portion 46.

[0033] Figure 7The brake pedal device 21 is shown when the driver applies a pedal force to the pedal portion 28 and the operating pedal 25 is stepped on when the vehicle 10 is not in a collision. The operating pedal 25 rotates forward with the operating shaft portion 24 as the center in accordance with the above-mentioned stepping operation. The rotation is transmitted to the push rod 43 via the connecting pin 47 and the clamp 44. The push rod 43 is driven (pushed forward), and the brake booster 40 works. The safety portion 80 and the rotating shaft portion 60 fix the rotating rod 51 to the pedal arm 26. Therefore, the rotating rod 51 is formed integrally with the operating pedal 25, and moves around the operating shaft portion 24, that is, at a position away from the collision bracket 14. The pushing portion 54 leaves the connecting plate portion 46 obliquely rearward and upward.

[0034] <When the vehicle 10 collides> from Figure 1 When the vehicle 10 is in a state where an external force (impact) is applied to the vehicle body 15 from the front due to a collision, the instrument panel 12 moves backward along with the brake pedal device 21. The distance between the instrument panel 12 and the collision bracket 14 is shortened. When the abutting portion 53 of the rotating rod 51 abuts against the collision bracket 14, the rotating rod 51 receives a load (reaction force) from the collision bracket 14. This load acts on the rotating shaft portion 60 and the safety portion 80.

[0035] When the load on the rotating rod 51 from the collision bracket 14 reaches a threshold value or more, the safety portion 80 is broken (cut off) by shearing or the like. The rotation shaft portion 60 is not broken. The fixing of the rotating rod 51 to the pedal arm 26 by the safety portion 80 is released. The rotating rod 51 can rotate relative to the pedal arm 26 around the rotation shaft portion 60.

[0036] The rotating rod 51 rotates forward, and the pressing portion 54 abuts against the connecting plate portion 46 from above. Figure 8 and Fig. 9 As shown in FIG. 1 , the pressing portion 54 presses the connecting plate portion 46 downward in a direction intersecting the axis L1 of the push rod 43, which is a direction orthogonal to the axis L1 of the push rod 43. The input shaft 42 is bent downward by the pressing. The operating pedal 25, especially the stepping portion 28, moves forward in the stepping direction by the bending. Figure 8 and Fig. 9 In FIG. 1 , the pedal arm 26 indicated by a two-dot chain line indicates the position of the pedal arm 26 before the collision of the vehicle 10. In this way, the operation pedal 25 is prevented from moving backward when the vehicle 10 collides.

[0037] Next, the effects of this embodiment will be described. (1) Figure 1 As shown, in this embodiment, the input shaft 42 of the brake booster 40 is connected to the pedal arm 26. In this embodiment, there is no Fig. 20 The push rod 106 connected to the connecting arm 107 in the prior art is detached from the connecting arm 107. Figure 1As shown, in this embodiment, even if the rotation lever 51 is deformed, the connection state of the input shaft 42 with respect to the pedal arm 26 is not affected. Therefore, in this embodiment, when the vehicle 10 is not in a collision, the input shaft 42 can be stably driven (pushed) in conjunction with the rotation of the pedal arm 26 regardless of the state of the rotation lever 51. When the vehicle 10 is not in a collision, the operation pedal 25 can be stepped on stably to operate the brake booster 40, similarly to a brake pedal device without a reverse movement prevention mechanism.

[0038] (2) Assuming that the vehicle body components (instrument panel reinforcement 13, collision bracket 14) are located at the same height as in the present embodiment, the effect of (1) above can be obtained even if the input shaft 42 is pushed from below by the push portion 54. However, in this case, since the push portion 54 is wound from below, the shape of the rotating rod 51 becomes complicated and large. In this regard, in the present embodiment, Figure 1 As shown, the pressing portion 54 is arranged below the vehicle body component (collision bracket 14) and above the input shaft 42. Therefore, the pressing portion 54 can press the input shaft 42 from above, and the shape of the rotating lever 51 can be simplified and compact.

[0039] (3) When the vehicle 10 collides, the safety portion 80 breaks, so that the rotating lever 51 can rotate relative to the pedal arm 26, as described above. In this case, if the flange portion 63 of the rotating shaft portion 60 abuts against the rod body portion 52, the sliding resistance between the flange portion 63 and the rod body portion 52 may make it difficult for the rotating lever 51 to rotate. In this regard, in the present embodiment, Figure 6 As shown in FIG. 1 , the pedal arm 26 is clamped from both sides by the large diameter portion 62 and the rivet portion 64, thereby fixing the small diameter portion 61 to the pedal arm 26. In this state, the flange portion 63 is separated from the rod body portion 52 by a gap G1. By setting this gap, the sliding resistance between the flange portion 63 and the rod body portion 52 can be reduced, and the rotating rod 51 can be easily rotated. The backward movement suppression performance of the backward movement suppression mechanism 50 can be improved.

[0040] (4) Figure 1 to Figure 4 As shown in FIG. 1 , the push portion 54 is in the shape of a plate extending in the vertical direction. Therefore, the strength of the push portion 54 in the vertical direction, which is the bending direction of the input shaft 42, can be increased. The push portion 54 can be prevented from being deformed when the input shaft 42 is bent. By designing the shape of the rotating lever 51 in this way, the strength of the push portion 54 in the vertical direction can be increased, and therefore, it is not necessary to add another component to achieve this purpose.

[0041] (5) Figure 5As shown, the front end of the rod body 52, that is, the portion of the push rod 43 parallel to the axis L1, can be used as the pressing portion 54. In this case, the left-right dimension of the pressing portion 54 is the same as the plate thickness of the rod body 52. ​​The contact area between the pressing portion 54 and the connecting plate 46 is small. Since the input shaft 42 can swing with the ball portion 43a as a fulcrum, when the pressing portion 54 presses the connecting plate 46 from the axis L1 to a position offset in the left-right direction, the following problem may occur. That is, when the connecting plate 46 is pressed at the above position with the smaller contact surface of the pressing portion 54, as shown by the arrow B, a force that rotates the input shaft 42 around the axis L1 is generated. The pressing portion 54 pushes the connecting plate 46 downward in a state where the left-right balance is lost. In other words, the pressing force of the pressing portion 54 is used as a force to rotate the input shaft 42 around the axis L1. As a result, the pressing force for bending the input shaft 42 becomes smaller, and there is a possibility that the bending efficiency decreases.

[0042] In this regard, in this embodiment, if Figure 4 As shown in FIG. 1 , the dimension of the pressing portion 54 in the left-right direction is larger than the plate thickness of the rod body portion 52. The contact area ratio between the pressing portion 54 and the connecting plate portion 46 is Figure 5 The comparative ratio is large. The pushing portion 54 pushes the connecting plate portion 46 downward in a balanced state in the left-right direction. Therefore, the rotation of the input shaft 42 around the axis L1 can be suppressed. The pushing force of the pushing portion 54 is difficult to be used as a force to rotate the input shaft 42 around the axis L1. The pushing force of the pushing portion 54 can be used more to bend the input shaft 42, and the reduction in bending efficiency can be suppressed. The input shaft 42 can be stably bent.

[0043] In addition, although the contact surface with the connecting plate portion 46 can be enlarged by adding another component to the rotating rod 51, the number of components will increase. In this embodiment, the pressing portion 54 as a part of the rotating rod 51 has a larger contact surface with the connecting plate portion 46, so there is no need to add another component.

[0044] (6) Figure 4 As shown, in this embodiment, a part (front end portion) of the plate material forming the rod body 52 is bent to form the pressing portion 54. In other words, the pressing portion 54 is formed integrally with the rod body 52. ​​Therefore, no other component for forming the pressing portion 54 is required.

[0045] (7) Fig. 20The conventional back-moving prevention mechanism shown in the figure is composed of a connecting arm 107, a first connecting rod 111, a second connecting rod 113, a first connecting shaft 112, a second connecting shaft 114, a third connecting shaft 115, and a rivet shaft 116. The number of components constituting the back-moving prevention mechanism is large. In particular, there are many shafts for rotation (the first connecting shaft 112 and the second connecting shaft 114). Therefore, not only the cost of components and the cost required for assembly increase, but also the back-moving prevention mechanism becomes large.

[0046] In view of this, in this embodiment, if Figure 1 As shown, the retreat suppression mechanism 50 is composed of a relatively small number of components, such as a rotating rod 51, a rotating shaft portion 60, and a safety portion 80. There is one shaft for rotation (only the rotating shaft portion 60). In addition, the rod body portion 52, the abutment portion 53, and the push portion 54 are composed of one component. Therefore, the component cost and the cost required for assembly can be reduced. In addition, the retreat suppression mechanism 50 can be made small, which can help save space.

[0047] (8) In the reverse movement prevention mechanism 50, by changing the position of at least one of the rotation shaft portion 60 and the safety portion 80, the load applied from the collision bracket 14 to the contact portion 53 or the strength of the input shaft being bent by the pressing portion 54 when the vehicle 10 collides can be adjusted.

[0048] Here, if Fig.10 and Fig.11 As shown, the distance from the axis L2 of the shaft portion 60 to the abutment portion 53 is R1, the distance from the axis L2 to the abutment position of the push portion 54 and the connecting plate portion 46 is R2, and the distance from the axis L2 to the axis L3 of the safety portion 80 is R3. Fig.10 Distances R1 to R3 indicated by solid lines represent distances R1 to R3 of the backward movement suppression mechanism 50 according to the present embodiment.

[0049] The ratio of the distance R1 to the distance R2 (R1 / R2) is defined as the bending rod ratio. By changing the position of the rotation shaft 60, at least one of the distances R1 and R2 can be changed, thereby changing the bending rod ratio (R1 / R2).

[0050] The load applied to the abutment portion 53 can be reduced by increasing the bending ratio (R1 / R2). For example, the position of the rotation shaft portion 60 is changed to the oblique front lower side, such as Fig.10 As shown by the two-dot chain line, the distance R1 is longer and the distance R2 is shorter than in the present embodiment. As a result, the bending bar ratio (R1 / R2) is larger than in the present embodiment, and the load applied to the contact portion 53 is reduced.

[0051] In contrast to the above, the bending amount of the input shaft 42 by the push portion 54 can be increased by reducing the bending ratio (R1 / R2), thereby improving the backward suppression effect. Fig.11 As shown by the two-dot chain line, the distance R1 is shorter and the distance R2 is longer than in the present embodiment. As a result, the bending lever ratio (R1 / R2) is smaller than in the present embodiment, and the amount by which the pressing portion 54 bends the input shaft 42 increases.

[0052] In addition, if Fig.10 and Fig.11 As shown, the ratio of distance R1 to distance R3 (R1 / R3) is defined as the breaking rod ratio. The breaking rod ratio (R1 / R3) can be changed by changing the position of at least one of the rotation shaft 60 and the safety portion 80 to change at least one of the distances R1 and R3.

[0053] The load applied to the abutment portion 53 can be reduced by increasing the breaking rod ratio (R1 / R3). For example, the position of the safety portion 80 is changed to the lower side, such as Fig.11 As shown by the middle dashed line, the distance R3 is shorter than that of the present embodiment. As a result, the broken rod ratio (R1 / R3) is larger than that of the present embodiment, and the load applied to the contact portion 53 is reduced.

[0054] In addition, if Figure 1 As shown, in the backward movement prevention mechanism 50 of this embodiment, only one rotating shaft portion 60 is used as an axis for rotation. Therefore, in this embodiment, it is easy to design the respective positions of the rotating shaft portion 60 and the safety portion 80, and it is also easy to set the target value for achieving the backward movement prevention performance required for the backward movement prevention mechanism 50 for each vehicle 10 to be optimal. In addition, the operation of each part of the backward movement prevention mechanism 50 is not likely to become complicated.

[0055] Also, in Fig. 20 In the conventional back-moving suppression mechanism shown in the figure, the same lever ratio design as in the present embodiment can also be performed. However, in the conventional back-moving suppression mechanism, multiple components (the first connecting shaft 112, the second connecting shaft 114) are used as the axis for rotation. Therefore, a complex design is required and it is not easy to design. In addition, the movement of each part of the back-moving suppression mechanism also becomes complicated.

[0056] (9) Figure 1 and Figure 6 As shown, the pedal arm 26 of the present embodiment is configured to be the same as or have the same outer shape as the pedal arm of a brake pedal device (not shown) that does not have the backward movement prevention mechanism 50. The shape of the pedal arm is not greatly changed to form the arm holes 31 and 32. Therefore, it is possible to prevent the pedal arm 26 from becoming larger due to the installation of the backward movement prevention mechanism 50.

[0057] In view of this, Fig. 20 In the conventional structure shown in FIG. 1 , the brake arm 104 and the connecting arm 107 connected to the brake arm 104 correspond to the pedal arm 26 in this embodiment. In addition, assuming that the conventional brake pedal device 100 does not have a reverse movement prevention mechanism, the connecting arm 107 is Fig. 20 In order to form the portion through which the first connecting shaft 112, the second connecting shaft 114 and the rivet shaft 116 are inserted, the connecting arm 107 has to be pressed Fig. 20 As shown by the solid line, it expands upward. Of the brake arm 104 and the connecting arm 107, which are parts corresponding to the pedal arm 26 of the present embodiment, the connecting arm 107 is enlarged.

[0058] The above-mentioned embodiment can also be implemented by making the following modifications. The above-mentioned embodiment and the following modifications can be implemented in combination with each other within the scope of no technical contradiction.

[0059] <About the rotation lever 51> ·like Fig.18 and Fig.19 As shown in FIG. 1 , when the rod body 52 is in the shape of a plate that is longer in the vertical direction than in the front-rear direction, a flange 57 extending in the vertical direction may be formed along the rear edge of the rod body 52. ​​The flange 57 is formed by forming the plate material used to form the rod body 52, and extending in one direction in the thickness direction. Fig.18 and Fig.19 The flange portion 57 is formed by bending to the left. By forming the flange portion 57, the rigidity of the rotating rod 51 can be improved. As a result, even if the rotating rod 51 is subjected to a large load from the collision bracket 14, it is possible to suppress the rotating rod 51 from being deformed or tilted to the left and right. In addition, when the input shaft 42 is bent by the push portion 54, it is possible to suppress the rotating rod 51 from being deformed due to the reaction force from the input shaft 42. In addition, there is no need to add other components for improving the rigidity of the rod body 52, which helps to reduce the cost of the rotating rod 51.

[0060] Furthermore, the flange 57 may be formed to extend in the vertical direction along the front edge portion instead of or in addition to the rear edge portion of the rod body portion 52. In addition, the flange 57 may be formed of another member independent of the rod body portion 52.

[0061] ·like Figure 5 As shown, a part of the rod body 52, that is, a part parallel to the axis L1 of the push rod 43, may be used as the push portion 54. In addition, when the push portion 54 protrudes from the left or right of the rod body 52, the left-right dimension of the push portion 54 may be changed to be larger or smaller than that in the above-mentioned embodiment.

[0062] The position where the pressing portion 54 presses the clamp 44 may be changed to a position different from the position of the connecting plate portion 46. In addition, the position where the pressing portion 54 presses the input shaft 42 may be changed to a position different from the position of the clamp 44.

[0063] At least one of the contact portion 53 and the pressing portion 54 may be formed of another member independent of the rod body portion 52 . The pressing portion 54 may press the input shaft 42 in a direction obliquely intersecting the axis L1 .

[0064] <About the shaft portion 60 and the safety portion 80> like Figure 12 to Figure 17 As shown, the shaft portion 60 and the safety portion 80 may also be changed to have a configuration different from that of the above-described embodiment.

[0065] ·exist Fig.12 In the modification shown, the arm hole 31 and the rod hole 55 are formed to have the same hole diameter. As the rotation shaft portion 60, a metal straight pin can be used, which is fitted into the arm hole 31 and the rod hole 55 and has a shaft portion 65 and a flange portion 66 with uniform diameters. In this case, the end of the shaft portion 65 away from the pedal arm 26 (left side) is exposed from the rod hole 55. The flange portion 66 is formed at the exposed end and has a larger diameter than the rod hole 55. The end of the shaft portion 65 away from the rod body portion 52 (right side) is exposed from the arm hole 31. At the exposed end, a rivet portion 67 having a larger radial size than the shaft portion 65 is formed by riveting the end.

[0066] Similar to the above embodiment, the rotation shaft portion 60, together with the safety portion 80, fixes the rotation lever 51 to the pedal arm 26 when the vehicle 10 is not in a collision, and becomes the rotation center of the rotation lever 51 in a collision. Figure 13 to Figure 17 The same applies to the rotation shaft portion 60 of each modified example.

[0067] ·exist Fig.12 In the modification shown, the arm hole 32 and the rod hole 56 are formed to have the same hole diameter. As the safety portion 80, a metal straight pin that is fitted into the arm hole 32 and the rod hole 56 and has a shaft portion 85 and a flange portion 86 with uniform diameters can be used. In this case, the end of the shaft portion 85 away from the pedal arm 26 (left side) is exposed from the rod hole 56. The flange portion 86 is formed at the exposed end and has a larger diameter than the rod hole 56. The end of the shaft portion 85 away from the rod body portion 52 (right side) is exposed from the arm hole 32. At the exposed end, a riveted portion 87 having a larger radial size than the shaft portion 85 is formed by riveting the end.

[0068] As in the above embodiment, the safety portion 80 fixes the rotating lever 51 to the pedal arm 26 together with the rotating shaft portion 60 in a state where the rotating lever 51 is positioned in the rotating direction around the rotating shaft portion 60 when the vehicle 10 is not in collision. Figure 13 to Figure 15 The same applies to each variation example.

[0069] ·like Fig.13 In the second modification shown, the rotating shaft portion 60 may also be formed by combining a bolt 68 and a nut 69, wherein the bolt 68 has a head portion 68a and a shaft portion 68b. In this case, the arm hole 31 and the rod hole 55 are formed to have the same hole diameter. The shaft portion 68b is inserted through the arm hole 31 and the rod hole 55. The head portion 68a may be arranged on the side opposite to the rod body portion 52 (right side) with respect to the pedal arm 26, or may be arranged on the side opposite to the pedal arm 26 (left side) with respect to the rod body portion 52. In addition, the nut 69 is screwed on the end of the shaft portion 68b on the side opposite to the head portion 68a.

[0070] In the second modified example, the shaft portion 60 can also change the interval between the head 68a of the bolt 68 and the nut 69. Therefore, even if a plurality of types of pedal arms 26 having different plate thicknesses are used, the shaft portion 60 can be applied to these pedal arms 26. By tightening the bolt 68 and the nut 69, the difference in plate thickness can be absorbed and the manufacturing cost can be reduced.

[0071] In addition, the following effects can be expected. This is because Fig.14 As shown in FIG. 1 , the rotation direction of the nut 69 to loosen is the same as the rotation direction of the rotating rod 51 when the back-retraction mechanism 50 is working. Therefore, the rotating rod 51 when the back-retraction mechanism 50 is working serves as a tool to loosen the nut 69. That is, Fig.14 As shown by arrow C in FIG. 1 , the nut 69 becomes loose due to the forward rotation of the rotating rod 51. Fig.14 In the figure, the counterclockwise direction of the arrow around the nut 69 is the direction in which the nut 69 is loosened, and the clockwise direction of the arrow is the direction in which the nut 69 is tightened. The tightening force between the bolt 68 and the nut 69 is reduced, and the rotating rod 51 is easy to rotate forward. The backward movement suppression performance of the backward movement suppression mechanism 50 can be improved.

[0072] Also, the shaft portion 60 composed of the bolt 68 and the nut 69 can also be used as Figure 15 to Figure 17 The rotating shaft portion 60 in each modification example. ·like Fig.13 As shown, Fig.13Similarly to the rotating shaft portion 60 in the figure, the safety portion 80 can also be formed by a combination of a bolt 88 and a nut 89. In this case, as in the above-mentioned embodiment, the rod hole 56 is formed to have a hole diameter smaller than the arm hole 32. The bolt 88 has a head 88a, a large diameter shaft portion 88b, and a small diameter shaft portion 88c with a diameter smaller than the large diameter shaft portion 88b. The head 88a is arranged on the side opposite to the rod body portion 52 (right side) relative to the pedal arm 26. The large diameter shaft portion 88b is inserted into most of the arm hole 32. The small diameter shaft portion 88c is inserted therein in a state spanning the entire rod hole 56 and a part of the arm hole 32. In addition, the nut 89 is screwed on the end of the small diameter shaft portion 88c on the side opposite to the head 88a (left side).

[0073] ·like Fig.15 In the third modification shown, a protrusion 91 having a circular outer shape is formed by stamping a part of the rod body 52 to cause plastic deformation, and the protrusion 91 can also be used as the safety portion 80. The protrusion 91 is engaged with the arm hole 32. The safety portion 80 does not sandwich the rod body 52 and the pedal arm 26 from both sides. However, since the rotation shaft portion 60 sandwiches the rod body 52 and the pedal arm 26 from both sides, this is not a problem.

[0074] According to the third modification, since a part of the rod body 52 functions as the safety portion 80, other components for fixing such as stepped pins and straight pins are not required. In addition, the rod hole 56 is not required. Furthermore, the cost required to form the safety portion 80 can be reduced.

[0075] In addition, the protrusion 91 may have an outer shape other than a circular shape. In this case, the shape of the arm hole 32 is changed to match the outer shape of the protrusion 91. ·like Fig.16In the fourth modification shown, the safety portion 80 may also be formed by resin molding using a resin material. In this case, the arm hole 32 and the rod hole 56 are formed to have the same hole diameter. The safety portion 80 includes a shaft portion 92, a flange portion 93, and a plurality of locking pieces 94. The shaft portion 92 is fitted into the rod hole 56 and at least the portion of the arm hole 32 adjacent to the rod hole 56. A portion of the shaft portion 92 enters the arm hole 32. The end of the shaft portion 92 away from the pedal arm 26 (left side) is exposed from the rod hole 56. The flange portion 93 is formed at the exposed end and has a larger diameter than the rod hole 56 in the radial direction. A plurality of locking pieces 94 extend from the outer peripheral portion of the shaft portion 92 toward the side away from the rod body portion 52 (right side) in the direction along the axis L3, and can be elastically deformed in the radial direction of the shaft portion 92. The top end of each locking piece 94 is exposed from the arm hole 32. The exposed portion of each locking piece 94 has a claw portion 94a protruding radially outward from the shaft portion 92. The distance between the shaft portion 92 and the claw portion 94a is smaller than the plate thickness of the pedal arm 26. In addition, the claw portion 94a of each locking piece 94 is locked to the peripheral portion of the arm hole 32 in the pedal arm 26.

[0076] When the rotating rod 51 is fixed to the pedal arm 26 by the safety part 80 of the fourth modified example, the safety part 80 is inserted through the rod hole 56 and the arm hole 32 in order, with the claw part 94a as a guide. The insertion is performed in a state where each locking piece 94 is elastically deformed toward the radial inner side of the shaft part 92. When the safety part 80 is inserted until the claw part 94a reaches a position exposed from the arm hole 32, each locking piece 94 is elastically deformed toward the radial outer side under the action of the elastic restoring force. The claw part 94a of each locking piece 94 is locked in the peripheral part of the arm hole 32 in the pedal arm 26. In this way, by utilizing the elasticity of the locking piece 94, the safety part 80 is inserted through the rod hole 56 and the arm hole 32 and locked, thereby fixing the rotating rod 51 to the pedal arm 26. This method is also called snap-on fixing.

[0077] According to the fourth modification, the work of fixing the rotating lever 51 to the pedal arm 26 by the safety portion 80 becomes simple. In addition, there is an advantage that the safety portion 80 can be formed at a low cost compared to using an iron pin as the safety portion 80.

[0078] The portion of the shaft 92 that enters the arm hole 32 positions the rotating lever 51 in the rotation direction about the shaft 60. The safety portion 80 fixes the rotating lever 51 to the pedal arm 26 together with the shaft 60 in the above-positioned state.

[0079] Here, the safety portion 80 formed of a resin-molded pin can be Fig.15 The safety portion 80 composed of a protrusion shape (protrusion) obtained by punching is formed with high precision, which can stabilize the accuracy of the above-mentioned positioning.

[0080] besides, Fig.17 A fifth modification is shown, in which a pedal arm 26 having a plate thickness ratio of Fig.16 The components with small plate thickness are used. Even in this case, since a part of the shaft portion 92 is fitted into the arm hole 32, the above-mentioned positioning function is not lost. In other words, even if multiple types of pedal arms 26 with different plate thicknesses are used, the safety portion 80 of this modified example can be applied to these pedal arms 26. Therefore, it contributes to the commonality of the components (safety portion 80).

[0081] As mentioned above Fig.17 As shown, using the plate thickness ratio Fig.16 When the pedal arm 26 is small, the total value T2 of the thickness of each of the pedal arm 26 and the rod body 52 is smaller than the distance T1 between the flange 93 and the claw 94a. When the pedal arm 26 is in contact with the claw 94a and the rod body 52 is in contact with the pedal arm 26, a gap G2 is generated between the rod body 52 and the flange 93. Through the gap G2, the rotating rod 51 can move in the direction along the axis L3 of the safety part 80. However, this movement is restricted by the flange 93.

[0082] In this case, the force of the safety portion 80 clamping the lever body 52 and the pedal arm 26 from both sides is small. However, since the lever body 52 and the pedal arm 26 are clamped from both sides by the shaft portion 60, this is not a problem.

[0083] In addition, generally, the strength of resin products is lower than that of metal products such as iron. Therefore, even if the shaft portion 92 of the modified example is formed to be larger than the above-mentioned embodiment (refer to Figure 6 )'s small diameter portion 83 is still thick and can be broken by shearing or the like.

[0084] The combination of the rotating shaft portion 60 and the safety portion 80 in the backward movement prevention mechanism 50 may also be changed to the above-mentioned embodiment and Figure 12 to Figure 17 The combinations used in the variation examples are different combinations.

[0085] <Other> As an alternative to the collision bracket 14 , the vehicle body component that the rotation lever 51 contacts when the vehicle 10 collides may be the instrument panel reinforcement 13 , or another component that is fixed to the instrument panel reinforcement 13 and is different from the collision bracket 14 .

[0086] A configuration in which the pressing portion 54 presses the input shaft 42 from below may be employed. As the pedal arm 26 , a pedal arm having a shape different from that of a pedal arm of a brake pedal device (not shown) which does not have the reverse movement prevention mechanism 50 may be used.

[0087] The vehicle operating pedal device can be widely applied to all devices such as a booster device that transmits the pedal force of the operating pedal. As such devices, in addition to the brake pedal device 21, a clutch pedal device, an accelerator pedal device, etc. can also be cited.

[0088] Each of the above-mentioned embodiments includes the configurations described in the following supplementary notes.
