[0009] <Base> The base portion 10 is a structure for realizing the function of the operating pedal device for a vehicle, and is a portion that serves as a base for assembling various components including a pedal arm 20, a telescopic device 30, and a link mechanism 40. The base portion 10 is fixed to the foot of the driver's seat in the vehicle. The portion of the base portion 10 on the rear side of the vehicle extends along the floor panel FP. The floor panel FP is a panel member that constitutes the floor of the vehicle. In addition, the portion of the base portion 10 on the front side of the vehicle extends along the footrest TB. The footrest TB is a panel member that constitutes the lower end portion of the front wall of the vehicle compartment. The footrest TB extends from the floor panel FP toward the front of the vehicle and diagonally upward ( Figure 1 ) in the upper left corner.

[0010] The base portion 10 includes a pedal support portion 11 and a rod support portion 12. The pedal support portion 11 is a portion that supports the pedal arm 20. The pedal support portion 11 is provided at a portion of the base portion 10 on the vehicle rear side. The rod support portion 12 is a portion that supports the link mechanism 40 (more specifically, the rod support shaft 60 described later). The rod support portion 12 is provided at a middle position in the vehicle front-rear direction of the base portion 10.

[0011] <Pedal Arm> The pedal arm 20 is an operating member that is stepped on by the driver of the vehicle. A pedal support shaft 21 is provided at the lower portion of the pedal arm 20. The outer surface of the pedal support shaft 21 is cylindrical. The center line of the pedal support shaft 21 (hereinafter referred to as the first center line L1) is oriented in the vehicle width direction (in the same direction as the vehicle width). Figure 1 Extending in a direction perpendicular to the paper plane).

[0012] In the present embodiment, the pedal support shaft 21 of the pedal arm 20 is supported by the pedal support portion 11 of the base portion 10. Thus, the lower portion of the pedal arm 20 is supported by the pedal support shaft 21. The pedal arm 20 extends upward from the pedal support shaft 21. The pedal arm 20 rotates around the first center line L1 of the pedal support shaft 21 in accordance with the pedal operation of the driver.

[0013] <Telescopic device> Examples of the telescopic device 30 include a master cylinder that applies oil pressure to a brake device of a vehicle for actuating the brake device, and a reaction force device that applies a reaction force to the pedal arm 20 when the driver steps on the pedal arm 20. In the present embodiment, the master cylinder is used as the telescopic device 30.

[0014] like Figure 1 and Figure 2 As shown, the telescopic device 30 is fixed to the vehicle front side portion of the base portion 10. The telescopic device 30 is fixed in a posture where the upper portion is inclined toward the vehicle front side relative to the lower portion. Thus, the telescopic device 30 is arranged in a posture extending along the footrest TB.

[0015] The telescopic device 30 is located on the front side of the vehicle relative to the pedal arm 20, that is, Figure 1 The pedal arm 20 and the telescopic device 30 are arranged at mutually overlapping positions when viewed from the rear side of the vehicle. The telescopic device 30 can be telescoped in a direction inclined relative to the vertical direction of the vehicle, specifically, in a direction along the footrest TB.

[0016] <Linkage> The link mechanism 40 is provided between the pedal arm 20 and the telescopic device 30. The link mechanism 40 is connected to the pedal arm 20 and the telescopic device 30, respectively. When the pedal arm 20 is rotated about the first center line L1 of the pedal support shaft 21 by the pedal operation of the driver, the link mechanism 40 converts the rotational motion of the pedal arm 20 into the telescopic motion of the telescopic device 30. The structure of the link mechanism 40 is described in detail below.

[0017] The link mechanism 40 includes a connecting link 50, a rod support shaft 60, and a connecting rod 70. In this embodiment, the components of the vehicle operating pedal device are arranged in the order of the pedal arm 20, the connecting link 50, the connecting rod 70, and the telescopic device 30 from the vehicle rear side.

[0018] <Connecting rod> The connecting link 50 extends between the pedal arm 20 and the connecting rod 70 so as to connect the two.

[0019] One end portion (hereinafter referred to as the first portion 51) in the length direction of the connecting link 50 is connected to the pedal arm 20. The first portion 51 is connected to the pedal arm 20 in a manner that allows relative rotation around the second center line L2 relative to the pedal arm 20. In the present embodiment, the second center line L2 extends parallel to the first center line L1 of the pedal support shaft 21. In detail, the first portion 51 is connected to the pedal arm 20 via the first pin 41 having the second center line L2.

[0020] The end portion (hereinafter referred to as the second portion 52) of the connecting link 50 on the side opposite to the first portion 51 in the longitudinal direction is connected to the first connecting portion 71 of the connecting rod 70. The second portion 52 of the connecting link 50 is connected to the first connecting portion 71 of the connecting rod 70 so as to be relatively rotatable about the third center line L3 relative to the connecting rod 70. In the present embodiment, the third center line L3 extends parallel to the first center line L1 of the pedal support shaft 21. In detail, the second portion 52 is connected to the first connecting portion 71 via the second pin 43 having the third center line L3.

[0021] <Rod Support Shaft> The rod support shaft 60 is rotatably supported by the rod support portion 12 of the base portion 10. The rod support shaft 60 is located on the vehicle front side ( Figure 1 The outer surface of the rod support shaft 60 is cylindrical. The center line of the rod support shaft 60 (hereinafter referred to as the fourth center line L4) is in the vehicle width direction (with Figure 1 The fourth center line L4 of the rod support shaft 60 extends in parallel with the first center line L1 of the pedal support shaft 21. The rod support shaft 60 is rotatable relative to the base portion 10 around the fourth center line L4.

[0022] <Connecting rod> The connecting rod 70 is fixed to the rod support shaft 60. The connecting rod 70 can rotate relative to the base portion 10 around the fourth center line L4 together with the rod support shaft 60. The connecting rod 70 is formed in a plate shape extending in the front-rear direction and the up-down direction of the vehicle. The connecting rod 70 extends in a manner connecting the connecting rod 50 and the telescopic device 30. When viewed from the extending direction of the first center line L1, the connecting rod 70 is roughly V-shaped. The connecting rod 70 has a supporting portion 73, the first connecting portion 71 and the second connecting portion 72. These supporting portions 73, the first connecting portion 71 and the second connecting portion 72 are arranged at three portions that form a convex shape toward the outside in the roughly V-shaped connecting rod 70.

[0023] The support portion 73 is a portion fixed to and supported by the rod support shaft 60. As described above, the first connection portion 71 is a portion connected to the second portion 52 of the connection link 50. The first connection portion 71 is located above the pedal support shaft 21 of the pedal arm 20.

[0024] The second connection portion 72 is a portion connected to the telescopic device 30. The connection portion of the telescopic device 30 has a spring hook 31 as a connection member that is U-shaped in a plan view, and a clevis pin 32 as a connection pin that is cylindrical. The center line of the clevis pin 32 (hereinafter referred to as the fifth center line L5) extends in the vehicle width direction. The fifth center line L5 of the clevis pin 32 extends parallel to the first center line L1 of the pedal support shaft 21. The second connection portion 72 of the connection rod 70 is connected to the telescopic device 30 via the spring hook 31 and the clevis pin 32. The clevis pin 32 is located at the lower end of the telescopic device 30. In the present embodiment, the telescopic device 30 is extended and reciprocated by the reciprocating movement of the lower end of the telescopic device 30.

[0025] like Figure 1 As shown, the connecting rod 70 has a structure in which, when viewed from the extension direction of the first center line L1, the third center line L3 of the first connecting portion 71, the fourth center line L4 of the supporting portion 73, and the fifth center line L5 of the second connecting portion 72 are arranged at positions corresponding to the three corners of an acute triangle. That is, the connecting rod 70 has a structure in which, when viewed from the extension direction of the first center line L1, when a triangle having the third center line L3, the fourth center line L4, and the fifth center line L5 as three vertices is drawn, the triangle becomes an acute triangle. In addition, as Figure 1 and Figure 3 As shown, the connecting rod 70 is arranged so that the third center line L3 of the first connecting portion 71 and the fifth center line L5 of the second connecting portion 72 are located below the fourth center line L4 of the supporting portion 73 in the vehicle vertical direction (hereinafter referred to as the lower side).

[0026] <Rotation Sensor> like Figure 2 As shown, the vehicle operating pedal device of this embodiment has a rotation sensor 80 for detecting the pedal operation amount of the pedal arm 20. The rotation sensor 80 is provided on the rod support shaft 60. In detail, the rotation sensor 80 is mounted on the rod support portion 12 of the base portion 10 in a manner connected to the rod support shaft 60. The rotation sensor 80 detects the angular position of the connecting rod 70 around the fourth center line L4, specifically, the angular position of the rod support shaft 60, and uses it as an index value of the driver's pedal operation amount. In this embodiment, the detection signal of the rotation sensor 80 is acquired by an electronic control device (not shown), and is used for the vehicle driving control of the electronic control device.

[0027] <Function> Below, refer to Figure 1 and Figure 3 The function of the vehicle operating pedal device of this embodiment will be described. Figure 1The operating pedal device for a vehicle is shown in a non-operating state where the pedal arm 20 is not being operated by being stepped on. Figure 3 The operating pedal device for a vehicle is shown in an operating state in which the pedal arm 20 is not being operated by being stepped on.

[0028] First, the operation of the vehicle operating pedal device when the pedal arm 20 is stepped on by the driver will be described. like Figure 1 and Figure 3 As shown in FIG. 1 , when the pedal arm 20 is stepped on, Figure 1 As shown by the middle arrow A1, the pedal arm 20 rotates in a manner of tilting toward the front of the vehicle with the first center line L1 of the pedal support shaft 21 as the rotation center. In conjunction with this, the first connecting portion 71 of the connecting rod 70 is connected to the second portion 52 of the connecting rod 50 toward the front of the vehicle and obliquely downward ( Figure 1 Thus, if Figure 1 As shown by the middle arrow A2, the connecting rod 70 rotates with the fourth center line L4 of the rod support shaft 60 as the rotation center. Figure 1 As shown by the arrow A3 in the middle, the second connecting portion 72 of the connecting rod 70 is directed toward the front of the vehicle and obliquely upward ( Figure 1 As a result, the telescopic device 30 is shortened. At this time, the telescopic device 30 generates oil pressure for actuating the braking device of the vehicle.

[0029] Next, the operation of the vehicle operating pedal device when the driver's depression operation on the pedal arm 20 is released will be described. When the pedal arm 20 is released from the pedal operation, Figure 3 As shown by the arrow B1 in the middle, the pedal arm 20 is rotated about the first center line L1 of the pedal support shaft 21 as the rotation center, so that the pedal arm 20 returns to the position before the pedal operation ( Figure 1 In response to this, the first connecting portion 71 of the connecting rod 70 is connected to the second portion 52 of the connecting rod 50 toward the rear of the vehicle and obliquely upward ( Figure 3 Thus, if Figure 3 As shown by the middle arrow B2, the connecting rod 70 rotates with the fourth center line L4 of the rod support shaft 60 as the rotation center. Figure 3 As shown by the arrow B3 in the middle, the second connecting portion 72 of the connecting rod 70 is directed toward the rear of the vehicle and obliquely downward ( Figure 3 As a result, the telescopic device 30 is extended. At this time, the telescopic device 30 stops generating the oil pressure for actuating the braking device of the vehicle.

[0030] <Effects> Hereinafter, the effects of the vehicle operating pedal device according to the present embodiment will be described. (1-1) The connecting rod 70 is formed in such a structure that, when viewed in the extending direction of the first center line L1, the third center line L3 of the first connecting portion 71, the fourth center line L4 of the support portion 73, and the fifth center line L5 of the second connecting portion 72 are arranged at positions corresponding to the three angles of an acute triangle.

[0031] According to the present embodiment, since the link mechanism 40 having such a connecting rod 70 and a connecting link 50 is provided, by setting the shapes of those connecting rod 70 and connecting link 50, the positional relationship between the pedal arm 20 and the telescopic device 30 can be determined with a high degree of freedom. Therefore, the vehicle operation pedal device can be arranged with a high degree of freedom.

[0032] A connecting rod having a structure in which the third center line L3 of the first connecting portion 71, the fourth center line L4 of the support portion 73, and the fifth center line L5 of the second connecting portion 72 are arranged at positions corresponding to the three angles of an obtuse triangle is used as a connecting rod of a comparative example. According to the present embodiment, compared with the case of using the connecting rod of the comparative example, the length of the connecting rod 70 in the vehicle front-rear direction can be shortened. As a result, the vehicle operation pedal device can be miniaturized so that the length of the entire vehicle operation pedal device in the vehicle front-rear direction is shortened. In this way, by miniaturizing the vehicle operation pedal device, the vehicle operation pedal device can also be arranged with a high degree of freedom.

[0033] (1-2) The connecting rod 70 is arranged such that the third center line L3 of the first connecting portion 71 and the fifth center line L5 of the second connecting portion 72 are located on the lower side than the fourth center line L4 of the support portion 73.

[0034] According to the present embodiment, compared with the case of using the connecting rod of the comparative example, the positions of the first connecting portion 71 and the second connecting portion 72 of the connecting rod 70 can be set on the lower side. Therefore, the connecting link 50 connected to the first connecting portion 71 or the telescopic device 30 connected to the second connecting portion 72 can be arranged on the lower side. Therefore, the vehicle operation pedal device can be made compact in the vehicle up-down direction.

[0035] In addition, it can be formed into a structure in which, as the pedal arm 20 is stepped on, the second connecting portion 72 of the connecting rod 70 moves obliquely upward and forward of the vehicle. As a result, the telescopic direction of the telescopic device 30 can be set to a direction inclined with respect to the vehicle up-down direction. Therefore, the telescopic device 30 can be arranged along a footrest TB extending in a direction inclined with respect to the vehicle up-down direction. Therefore, the telescopic device 30 can be arranged in the space under the driver's seat with high space efficiency.

[0036] (1-3) A rotation sensor 80 is mounted on the rod support shaft 60. According to the present embodiment, the rotation sensor 80 is used to detect the angular position of the connecting rod 70 around the fourth center line L4, thereby detecting the amount of operation of the pedal arm 20. In addition, since the rotation sensor 80 is arranged on the front side of the vehicle relative to the pedal arm 20, compared with the case where the rotation sensor 80 is arranged on the pedal support shaft 21, a structure can be formed in which the rotation sensor 80 and the driver's foot are not easily interfered. As a result, it is also possible to suppress foreign matter (water, mud) from adhering to the rotation sensor 80 through the driver's shoes. Therefore, the durability and reliability of the rotation sensor 80 can be improved.

[0037] [Second embodiment] The following mainly focuses on the differences from the first embodiment. Figures 4 to 6 A second embodiment of the vehicle operating pedal device will be described. In addition, in the following, among the various structures of this embodiment, the same structures as those of the first embodiment are denoted by the same reference numerals or corresponding reference numerals, and duplicate descriptions of those structures will be omitted.

[0038] The vehicle operating pedal device of the present embodiment is different from the vehicle operating pedal device of the first embodiment in the positional relationship between the pedal arm and the telescopic device, the length of the rod support shaft, and the structure of the connecting rod. <Positional Relationship between Pedal Arm and Telescopic Device> like Figure 4 and Figure 5 As shown, in the present embodiment, the pedal arm 120 and the telescopic device 30 are disposed at positions offset in the vehicle width direction so as not to overlap each other when viewed from a direction perpendicular to the first center line L1 of the pedal support shaft 21. Specifically, the pedal arm 120 is disposed on the right side of the telescopic device 30 when viewed from the rear side of the vehicle. That is, the telescopic device 30 is disposed on the left side of the pedal arm 120 when viewed from the rear side of the vehicle.

[0039] <Length of rod support shaft> like Figures 4 to 6 As shown, the rod support shaft 160 is provided so that the fourth center line L4 extends in the vehicle width direction. The rod support shaft 160 extends between the pedal arm 120 and the telescopic device 30. The rod support shaft 160 extends from the portion of the pedal arm 120 corresponding to the front of the vehicle to the portion of the telescopic device 30 corresponding to the rear of the vehicle.

[0040] <Structure of connecting rod> In the present embodiment, the connecting rod 100 connecting the connecting rod 50 and the telescopic device 30 is composed of two rod members, namely, a first connecting rod 101 and a second connecting rod 102. A support portion 101A of the first connecting rod 101 is fixed to and supported by the rod support shaft 160. In addition, a support portion 102A of the second connecting rod 102 is fixed to and supported by the rod support shaft 160. The first connecting rod 101 and the second connecting rod 102 can rotate relative to the base portion 110 together with the rod support shaft 160 around the fourth center line L4 of the rod support shaft 160.

[0041] The first connecting rod 101 and the second connecting rod 102 are formed in a plate shape extending in the front-rear direction and the up-down direction of the vehicle. The first connecting rod 101 is arranged in the front of the vehicle connecting the connecting rod 50 and the pedal arm 120. The first connecting portion 71 of the first connecting rod 101 is connected to the connecting rod 50. In the present embodiment, the rod support shaft 160 and the pedal arm 120 are connected via the connecting rod 50 and the first connecting rod 101. The second connecting rod 102 is arranged in the rear of the vehicle of the telescopic device 30. The second connecting portion 72 of the second connecting rod 102 is connected to the telescopic device 30. In the present embodiment, the rod support shaft 160 and the telescopic device 30 are connected via the second connecting rod 102.

[0042] like Figure 6 As shown, in this embodiment, the connecting rod 100 composed of the first connecting rod 101 and the second connecting rod 102 has the following structure. When viewed from the extending direction of the first center line L1, the connecting rod 100 composed of the first connecting rod 101 and the second connecting rod 102 is substantially V-shaped. The supporting portion 101A of the first connecting rod 101 and the supporting portion 102A of the second connecting rod 102 are arranged at one of the three portions that are convex toward the outside in the substantially V-shaped connecting rod 100. Specifically, the supporting portion 101A of the first connecting rod 101 and the supporting portion 102A of the second connecting rod 102 are arranged at the portion where the first connecting rod 101 and the second connecting rod 102 overlap when viewed from the extending direction of the first center line L1. The first connecting portion 71 of the first connecting rod 101 and the second connecting portion 72 of the second connecting rod 102 are arranged at the remaining two of the three portions that are convex toward the outside in the substantially V-shaped connecting rod 100.

[0043] The connecting rod 100 is configured such that, when viewed from the extending direction of the first center line L1, the third center line L3 of the first connecting portion 71, the fourth center line L4 of the rod support shaft 160, and the fifth center line L5 of the second connecting portion 72 are arranged at positions corresponding to the three corners of an acute triangle. That is, the connecting rod 100 is configured such that, when a triangle having the third center line L3 of the first connecting portion 71, the fourth center line L4 of the rod support shaft 160, and the fifth center line L5 of the second connecting portion 72 as three vertices is drawn, the triangle becomes an acute triangle. In addition, the connecting rod 100 is arranged in such a manner that the third center line L3 of the first connecting portion 71 and the fifth center line L5 of the second connecting portion 72 are located on the lower side than the fourth center line L4 of the rod support shaft 160. In the present embodiment, the fourth center line L4 corresponds to the fourth center line of the support portion 101A of the first connecting rod 101 , and corresponds to the fourth center line of the support portion 102A of the second connecting rod 102 .

[0044] <Effects> According to the vehicle operating pedal device of the present embodiment, in addition to the effects described in (1-1) to (1-3) above, the following effects described in (2-1) are obtained.

[0045] (2-1) The pedal arm 120 and the telescopic device 30 are arranged at positions offset in the vehicle width direction so as not to overlap each other when viewed from a direction perpendicular to the first center line L1 of the pedal support shaft 21. According to this embodiment, the vehicle operating pedal device can be formed into a structure in which the telescopic device 30 does not become an obstacle when the pedal arm 120 is stepped on. Therefore, compared with a device in which the pedal arm 120 and the telescopic device 30 are arranged at a position in which they overlap each other when viewed from the rear side of the vehicle, the pedal arm 120 can be arranged on the front side of the vehicle. As a result, the vehicle operating pedal device can be made into a compact structure in the front-rear direction of the vehicle.

[0046] [Other embodiments] In addition, the above-mentioned embodiments can be implemented as the following modifications. The above-mentioned embodiments and the following modifications can be implemented in combination with each other within the scope of no technical contradiction.

[0047] In each embodiment, instead of using the master cylinder as the telescopic device 30, a reaction force device can be used as the telescopic device 30. In this case, the pedal arm 20, 120 can also be used for an accelerator pedal or a clutch pedal.

[0048] The telescopic device 30 may be arranged substantially horizontally so as to extend in the vehicle front-rear direction. In this case, the telescopic device 30 may be arranged so as to extend along the floor panel FP.

[0049] In each embodiment, the shape of the connecting rods 70 and 100 is formed in a substantially triangular shape when viewed from the extending direction of the first center line L1, and the shape can be arbitrarily changed. In each embodiment, the connecting rods 70 and 100 may be arranged so that the third center line L3 and the fifth center line L5 are located above the fourth center line L4.

[0050] The vehicle operating pedal device of each embodiment can also be applied to a vehicle operating pedal device provided with a detection switch for detecting the presence or absence of a stepping operation of the pedal arm 20 , 120 as the rotation sensor 80 .

[0051] The vehicle operating pedal device of each embodiment can also be applied to a vehicle operating pedal device that is not provided with the rotation sensor 80 .
