The support member 14 includes a left support member 20, a right support member 22, and an upper middle support member 24, and is fixed to the vehicle (for example, a dash panel P). The left support member 20 and the right support member 22 are coupled to the upper middle support member 24 lion the front ends across the upper ends of the left support member 20 and the right support member 22, and face each other in the left-and-right direction. The left support member 20 is provided with a left pivot hole 21. The right support member 22 is provided with a right pivot hole 23. The boss 18 of the operating pedal 12 is disposed between the left pivot hole 21 and the right pivot hole 23 to cause the left pivot hole 21 and the right pivot hole 23 to communicate with each other in the left-and-right direction via the collar 29 in the boss 18. With the pivot holes communicating with each other, a pivot bolt 26 is passed through the collar 29 in the boss IS from the left pivot hole 21 to the right pivot hole 23.
The head of the pivot bolt 26 is in contact with the left support member 20 while the end of the pivot bolt 26 protrudes to the right from the right support member 22. The protruding portion of the pivot bolt 26 is screwed into a nut 30. Consequently, the left and right ends of the collar 29 are sandwiched between the left support member 20 and the right support member 22 to maintain a constant distance in the left-and-right direction between (the left pivot hole 21 of) the left support member 20 and (the right pivot hole 23 of) the right support member 22. Furthermore, a circular flange of one of the bushings 28 is placed at the left end of the boss 18 and between the boss 18 and the left support member 20. Moreover, the circular flange of the other bushing 28 is placed at the right end of the boss 18 and between the boss 18 and the right support member 22.
In this manner, the boss 18 at the upper end of the operating pedal 12 is supported between (the left pivot bole 21 of) the left support member 20 and (the right pivot hole 23 of) the right support member 22 in such a manner as to allow pivotal rotation. When the stepping part 16 at the lower end of the operating pedal 12 is stepped forward, the operating pedal 12 pivots via, for example, the pivot bolt 26 and the collar 29 that have been inserted in the boss 18.
A dot-and-dash line indicated by a reference sign 13 indicates a straight line that is the center on which the operating pedal 12 pivots (hereinafter referred to as the “pivot center line”). Moreover, the tipper end surface of the operating pedal 12 forms a curved shape that is equidistant from the pivot center line 13 of the operating pedal 12.
The vehicle operating pedal apparatus 10A is provided with an angle sensor 50. The angle sensor 50 detects the angle of rotation of the operating pedal 12 that pivots on the pivot center line 13, and includes an IC (Integrated Circuit) holder 52 and a magnet holder 54. An IC 56 is fixed to and exposed from the IC holder 52. A magnet 58 is fixed to and exposed from the magnet holder 54. The IC 56 is a magnetic field sensor that detects the magnetic field of the magnet 58. Examples of the IC 56 include a Hall IC.
As long as the IC 56 can detect the magnetic field of the magnet 58, it is not necessary for the IC 56 and the magnet 58 to be exposed. The same point is valid with regard to the following embodiments and modifications.
The IC holder 52 is substantially cuboid in shape. A snap-fit portion 60 and a screw hole 62 are provided to the left surface of the IC holder 52. A connector 64 is provided to the back surface of the IC holder 52. A cuboid block is formed, protruding, on the lower part of the right surface of the IC holder 52. The IC 56 is placed on the right side surface of the block.
The IC holder 52 is attached to the left support member 20 with the left surface of the IC holder 52 in contact with the inner surface (right surface) of the left support member 20. Hence, a first mounting hole 31 and a second mounting bole 32 are provided in the left support member 20 between the upper end of the left support member 20 and the left pivot hole 21. The protruding snap-fit portion 60 is inserted from the right side of the first mounting hole 31, and locked into the first mounting hole 31. Amounting bolt 66 is passed through the second mounting hole 32 from the left side of the second mounting hole 32. Furthermore, the mounting bolt 66 is assembled into the screw hole 62. The IC holder 52 is attached to the inner surface (right surface) of the left support member 20 in this manner, which places the IC 56 between the left support member 20 and the right support member 22 (that is, on the inner side).
The magnet holder 54 includes a flat portion 55 and a curved portion 57. The curved portion 57 of the magnet holder 54 is curved with a radius of curvature substantially equal to that of the upper end surface of the operating pedal 12. The flat portion 55 of the magnet holder 54 extends downward from the left end of the curved portion 57 of the magnet holder 54. Furthermore, the magnet 58 that is laid in an arc shape with a radius substantially equal to the distance from the pivot center line 13 to the IC 56 is provided on the left surface of the flat portion 55 of the magnet holder 54. The magnet holder 54 is attached to the upper end surface of the operating pedal 12. In order to attach the magnet holder 54, the magnet holder 54 is provided with a snap-fit portion 68. The snap-fit portion 68 has a protruding shape, and is inserted and locked into the upper end of the operating pedal 12. The magnet holder 54 is attached to the upper end of the operating pedal 12 in this manner. As a result, the curved portion 57 of the magnet holder 54 covers the upper end surface of the operating pedal 12, and the flat portion 55 of the magnet holder 54 covers an area above the boss 18 on the left surface of the operating pedal 12. Furthermore, the center of the arc of the magnet 58 provided on the left surface of the flat portion 55 of the magnet holder 54 is located on the pivot center line 13. Consequently, the magnet 58 of the magnet holder 54 faces the IC 56 of the IC holder 52 in the left-right direction in the area above the boss 18 on the left surface of the operating pedal 12.
In other words, the IC 56 and the magnet 58 face each other in a position that is closer to the boss 18 (that is, to the pivot bolt 26 and the collar 29) than the upper end surface of the operating pedal 12.
The magnet holder 54 is provided with a cover 70. The cover 70 juts out toward the right surface of the IC holder 52 from the upper and back edges of the flat portion 55 of the magnet holder 54 that has a fan shape in side view. Consequently, the cover 70 is disposed in an outer space that touches a gap across which the IC 56 and the magnet 58 face each other, along the upper and back edges of the flat portion 55 of the magnet holder 54 that has a fan shape in side view, and obscures the gap across which the IC 56 and the magnet 58 face each other.

A snap-fit portion 68B is provided on the right surface of the magnet holder 54B. The snap-fit portion 68B has a protruding shape, and is inserted and locked into the second latch hole 34 of the operating pedal 121. On the other hand, a magnet 58B and a snap-fit portion 69B are provided on the left surface of the magnet holder 54B. The magnet 58B is laid on the left surface of the magnet holder 54B in an arc shape with a radius substantially equal to the distance from the pivot center line 13 to the IC 56, and fixed to and exposed from the left surface of the magnet holder 54B. The snap-fit portion 69B has a protruding shape, and is inserted and locked into the first latch hole 33 of the operating pedal 128. The magnet holder 54B is attached to the tipper end of the operating pedal 128 in this manner. As a result, a part of the upper end surface of the operating pedal 12D is formed on the upper surface of the magnet holder 54B. Furthermore, the center of the are of the magnet 58B provided on the left surface of the magnet holder 54B is located on the pivot center line 13.
Consequently, the IC 56B and the magnet 58B face each other in the left-and-right direction in a position that is closer to die boss 18 (that is, to the pivot bolt 26 and the collar 29) than the upper end surface of the operating pedal 12B.
The magnet holder 54B is provided with a cover 70B. The cover 70B juts out upward and backward of the IC bolder 52B from the upper and back edges of the left surface of the magnet holder 54B. Consequently, the cover 70B is disposed in an outer space that touches a gap across which the IC 56B and the magnet 58B face each other, along the upper and back edges of the left surface of the magnet holder 54B, and obscures the gap across which the IC 56B and the magnet 58B face each other.

Furthermore, the magnet 58C is laid on and exposed from the upper surface of the curved portion 57C of the magnet holder 54C, on a center line passing through the middle in the left-and-right direction of the upper surface. The flat portion 55C of the magnet holder 54C extends downward from the left end of the curved portion 57C of the magnet holder 54C. The magnet holder 54C is attached to the upper end surface of the operating pedal 12. In order to attach the magnet holder 54C, the magnet holder 54C is provided with two snap-fit portions 68C and 69C. The snap-fit portion 68C has a protruding shape, and is inserted and locked into the left surface of the operating pedal 12. The snap-fit portion 69C has a groove shape, and is fitted to the upper end of the operating pedal 12. The magnet holder 54C is attached to the upper end of the operating pedal 12 in this manner. As a result, the curved portion 57C of the magnet holder 54C covers the upper end surface of the operating pedal 12, and the flat portion 55C of the magnet holder 54C covers an area above the boss 18 on the left surface of the operating pedal 12.
Consequently, the magnet 58C provided on the upper surface of the curved portion 57C of the magnet holder 54C is located, in an are shape that is equidistant from the pivot center line 13, on the upper end surface of the operating pedal 12, and faces the IC 56C in the up-and-down direction in roughly the middle between the left support member 20 and the right support member 22.
The magnet holder 54C is provided with a cover 70C. The cover 70C juts out further to the right than the IC holder 52C from the right end surface of the curved portion 57C of the magnet holder 54C. Consequently, the cover 70C is disposed in an outer space that touches a gap across which the IC 56C and the magnet 58C face each other, along the right end surface of the curved portion 57C of the magnet holder 54C, and obscures the right side of the gap across which the IC 56C and the magnet 58C face each other.

Hence, the first link pin 142 supports the link member 140 in such a manner that the link member 140 is pivotable relative to the first operating pedal 111. On the other hand, the second link pin 144 is placed in the front part of the link member 140 and couples the link member 140 and the second operating pedal 112. Hence, the second link pin 144 supports the link member 140 in such a manner that the link member 140 is pivotable relative to the second operating pedal 112.
Therefore, in the vehicle operating pedal apparatus 100, when the tread 116 at the lower end of the first operating pedal 111 is stepped forward, the first operating pedal 111 pivots on the first shaft 125. Such pivotal rotation of the first operating pedal 111 is transmitted to the second operating pedal 112 via the link member 140. Consequently, the second operating pedal 112 pivots on the second shaft 138.
The vehicle operating pedal apparatus 100 is provided with an angle sensor 150. The angle sensor 150 detects the angle of rotation of the second operating pedal 112 that pivots on the pivot center line 113. As illustrated in
The IC holder 152 is substantially cuboid in shape. The left surface of the IC holder 152 is provided with, for example, a protruding snap-fit portion 160. The back surface of the IC holder 152 is provided with a connector 164. A cuboid block 153 is formed, protruding, on the lower part of the right surface of the IC holder 152. The IC 156 is placed on the right side surface of the block.
The IC holder 152 is attached to the left support member 120 with the left surface of the IC holder 152 in contact with the inner surface (right surface) of the left support member 120. Hence, the snap-fit portion 160 is inserted from the right side of a mounting hole provided in the left support member 120, and locked into the mounting hole. The IC holder 152 is attached to the inner surface (right surface) of the left support member 120 in this manner, which places the IC 156 of the IC holder 152 between the pair of support members 114 (that is, on the inner side).
The magnet 158 is fixed to and exposed from the left surface of the lower end of the second operating pedal 112 above the second shaft 138 (that is, the boss of the second operating pedal 112). The magnet 158 is placed in an arc shape with a radius substantially equal to a distance from the pivot center line 113 to the IC 156. Furthermore, the center of the arc of the magnet 158 is located on the pivot center line 113. Consequently, the magnet 158 faces the IC 156 of the IC holder 152 in the left-and-right direction in an area above the second shaft 138 on the left surface of the lower end of the second operating pedal 112. In other words, the IC 156 and the magnet 158 face each other in a position that is closer to the pivot bolt 139 of the second shaft 138 than the lower end surface of the second operating pedal 112.
In the above description, in the vehicle operating pedal apparatus 100, the IC 156 of the angle sensor 150 is provided between the pair of support members 114 (that is, on the inner side) and the magnet 158 of the angle sensor 150 is provided at the lower end of the second operating pedal 112, facing the IC 156. Such a configuration allows the space for mounting the angle sensor 150 that detects the angle of rotation of the second operating pedal 112 to be made compact in the vehicle operating pedal apparatus 100.
Moreover, in the vehicle operating pedal apparatus 100, the IC 156 and the magnet 158 face each other in the position that is closer to the pivot bolt 139 of the second shaft 138 than the lower end surface of the second operating pedal 112. Consequently, the space for mounting the angle sensor 150 can be made more compact in the vehicle operating pedal apparatus 100.
Parenthetically, in such a modification, the second operating pedal 112 is an example of an “operating pedal.” The lower end surface of the second operating pedal 112 is an example of a “side surface at one end of an operating pedal.” The pivot hole provided in the support member 114 is an example of a “hole provided in a support member.” The pivot bolt 139 of the second shaft 138 is an example of a “pivot axis member.” The IC 156 is an example of a “Hall device.”
Moreover, a seventh embodiment is described below with reference to
As illustrated in
The IC holder 52B is substantially cuboid in shape, and the back surface of the IC holder 52G is provided with the connector 64. A snap-fit portion 60G is provided close to the connector 64 on the right surface of the IC holder 52G. A screw hole 62G is provided to a place at a corner where the front and upper surfaces of the IC holder 52G intersect, a place projecting in such a manner as to extend off the corner, and penetrates the place along the left-and-right direction. Hence, in the left support member 20, a second mounting hole 32G into which the mounting bolt 66 protruding from the screw hole 62G is screwed is provided in the middle between the front part and the upper part relative to the first mounting hole 31 into which the snap-fit portion 60G is inserted and locked.
Therefore, a female thread is formed in each of the screw hole 62G of the IC holder 52G and the second mounting hole 32G of the left support member 20. However, a female thread may not be formed in the screw hole 62G of the IC holder 52G.
A cuboid protrusion 72 is provided between the snap-fit portion 60G and the screw hole 62G on the right surface of the IC holder 52G. The protrusion 72 protrudes to the right from the right surface of the IC holder 52G. An IC 56G is fixed inside the protrusion 72. A part of the IC 56G is exposed in a window 74 provided in the right side surface of the protrusion 72.
The IC holder 52G is attached to the left support member 20 with the right surface (excluding the protrusion 72) of the IC holder 52G in contact with the outer surface (left surface) of the left support member 20. Hence, the left support member 20 is provided with an insertion hole 37 between the first mounting hole 31 and the second mounting hole 32G. The protrusion 72 of the IC holder 52G is inserted into the insertion hole 37 from the left side of the insertion hole 37. Consequently, the protrusion 72 of the IC holder 52G protrudes to the right from the right, side of the insertion hole 37 through the insertion hole 37. The snap-fit portion 60G of the IC holder 52G is inserted and locked into the first mounting hole 31 from the left side of the first mounting hole 31. Moreover, the mounting bolt 66 is screwed into the screw hole 62G of the IC holder 52G from the left side of the screw hole 62G. Consequently, the mounting bolt 66 protrudes to the right from the right side of the screw hole 62G through the screw hole 62G of the IC holder 52G. The protruding portion of the mounting bolt 66 is screwed into the second mounting hole 320 of the left support member 20 from the left side of the second mounting hole 32G.
The magnet holder 54 is similar to that of the first embodiment, excluding a cover 70G. The cover 70G does not obscure a gap across which the IC 56G and the magnet 58 face each other, unlike the first embodiment.
The IC holder 52G is attached to the outer surface (left surface) of the left support member 20 in this manner, which places a part (that is, the right half) of the IC 56G of the IC holder 52G between the left support member 20 and the right support member 22 (that is, on the inner side) in a position further to the right than the insertion hole 37 of the left support member 20. On the other hand, the remaining portion (that is, the left half) of the IC 56G of the IC holder 52G is placed in the insertion hole 37 of the left support member 20. Consequently, the IC 56G of the IC holder 52G faces the magnet 58 of the magnet holder 54 in the left-and-right direction in an area above the boss 18 on the left surface of the operating pedal 12.
The entire IC 56G of the IC holder 52G may be placed between the left support member 20 and the right support member 22 (that is, on the inner side) with the protrusion 72 of the IC holder 52G in the insertion hole 37 of the left support member 20.
In the above description, in the vehicle operating pedal apparatus 10G according to the seventh embodiment, the IC 56G of the angle sensor 50G is provided between the left support member 20 and the right support member 22 (that is, on the inner side), and the magnet 58 of the angle sensor 50G is provide at the upper end of the operating pedal 12, facing the IC 56G. Such a configuration allows the space for mounting the angle sensor 50G that detects the angle of rotation of the operating pedal 12 to be made compact in the vehicle operating pedal apparatus 10G according to the seventh embodiment.
Moreover, in the vehicle operating pedal apparatus 10G according to the seventh embodiment, the IC 56G and the nag net 58 face each other in a position that is closer to the boss 18 (that is, to the pivot bolt 26 and the collar 29) than the upper end surface of the operating pedal 12. Consequently, the space for mounting the angle sensor 50G can be made more compact in the vehicle operating pedal apparatus 10G according to the seventh embodiment.
The magnet 58 of the vehicle operating pedal apparatus 10G according to the seventh embodiment is provided, in an are shape that is equidistant from the pivot center line 13 of the operating pedal 12, in the position that is closer to the boss 18 (that is, to the pivot bolt 26 and the collar 29) than the upper end surface of the operating pedal 12 as in the first embodiment. Hence, the detection accuracy of the IC 56G is improved also in the vehicle operating pedal apparatus 10G according to the seventh embodiment.
Parenthetically, in the seventh embodiment, the upper end surface of the operating pedal 12 is an example of a “side surface at one end of an operating pedal.” The left pivot hole 21 and the right pivot hole 23 are examples of “holes provided in support members,” The pivot bolt 26 and the collar 29 are examples of “pivot axis members.” The left support member 20 and the right support member 22 are an example of a “pair of support members.” The IC holder 52G is an example of a “device holder” The IC 56G is an example of a “Hall device.”
