One embodiment of a pedal device for a vehicle will be described with reference to FIGS.
As shown in FIG. 1, a pedestal 10 fixed to the vehicle is provided in the vehicle pedal device. A hinge portion 20 is supported on the base 10, and a lower end portion of a rectangular plate-shaped pad 30 is connected to an upper end portion of the hinge portion 20. The pad 30 can be rotated around the hinge portion 20 about the short direction as a rotation center.

  The vehicle pedal device is provided with a housing 40 fixed to the vehicle. The housing 40 is disposed at a position above the pad 30. The housing 40 includes a box-shaped box portion 41 having an open lower end portion, and a rotating shaft 42 that is disposed inside the box portion 41 and is supported so as to extend in the short direction of the pad 30. Is provided. The box 41 is provided with a rotation angle sensor 43 that detects the rotation angle of the rotation shaft 42. The housing 40 and the pad 30 are connected via a rod 50. The rod 50 has an insertion part 51 extending in the short direction of the pad 30 and a connection part 52 extending upward from one end of the insertion part 51. The upper end portion of the connecting portion 52 is accommodated in the housing 40, and the upper end of the connecting portion 52 is connected to the peripheral surface of the rotating shaft 42. The rod 50 is provided so as to be rotatable about the rotation shaft 42 as a rotation center. The insertion portion 51 of the rod 50 is arranged to be slidable in the longitudinal direction of the pad 30 with respect to the back surface 30 </ b> A of the pad 30. The housing 40 is provided with a spring 44 that rotates the rod 50 in a direction in which the rod 50 is pressed against the pad 30.

  As shown in FIG. 2, the pedestal 10 has a fixed plate 11 configured in a plate shape. The fixed plate 11 has a substantially constant thickness and a rectangular top surface. The fixing plate 11 is arranged so that the longitudinal direction thereof is the same as the short direction of the pad 30. The fixed plate 11 is provided with a support portion 12 that protrudes upward from the upper surface of the fixed plate 11. The support portion 12 has a substantially rectangular parallelepiped shape extending in the longitudinal direction of the fixed plate 11. The support portion 12 is provided with a locking groove 13 continuously cut out from one end to the other end in the longitudinal direction. The locking groove 13 has a wide bottom end and a substantially convex cross section. The upper end portion of the locking groove 13 is open on the upper surface of the support portion 12.

  The hinge part 20 is provided with a locking part 21. The locking portion 21 has an insertion piece 22 that has substantially the same shape as the locking groove 13, and a locking piece 23 that is connected to the upper end of the insertion piece 22. The locking piece 23 is wider than the upper end of the locking groove 13 and covers the upper surface of the support portion 12. The insertion piece 22 is inserted into the locking groove 13, and the upper end portion of the support portion 12 is sandwiched between the insertion piece 22 and the locking piece 23. As a result, the locking portion 21 is locked to the support portion 12, and the hinge portion 20 is supported by the base 10. A thin plate-like hinge 24 extending upward is provided at the upper end of the locking portion 21. The hinge 24 is made of, for example, an elastic resin. At the upper end of the hinge 24, a coupling portion 25 coupled to the lower end portion of the pad 30 is provided. As shown in FIG. 3, the coupling portion 25 is, when viewed from the short direction of the pad 30, the front surface 26 located on the back surface 30 </ b> A side of the pad 30 and the operation surface 30 </ b> B side on the opposite side of the back surface 30 </ b> A. And a rear surface 27 located at the rear. The front surface 26 is inclined by a predetermined angle θ with respect to the upper surface of the locking portion 21 so as to be positioned higher as the distance from the hinge 24 increases. The predetermined angle θ is set so that the virtual plane X including the front surface 26 and the virtual plane Y including the upper surface of the locking portion 21 are not parallel to each other when the pad 30 is rotated by a stepping operation by the driver. Has been. The rear surface 27 includes a first connection surface 27A that extends substantially parallel to the upper surface of the locking portion 21, and a second connection surface 27B that extends downward from the operation surface 30B of the pad 30 along the operation surface 30B.

  As shown in FIG. 2, the fixing plate 11 of the pedestal 10 is positioned between two bolt holes 14 that are spaced apart from each other in the longitudinal direction, and protrudes upward from the upper surface of the fixing plate 11. A curved portion 15 having a curved upper surface is provided. In the orthogonal direction perpendicular to the short direction of the pad 30 on the upper surface of the fixed plate 11, the bending portion 15 is located on the back surface 30 </ b> A side of the pad 30, that is, on the housing 40 side relative to the support portion 12. One end of the bending portion 15 in the orthogonal direction is connected to the support portion 12, and the bending portion 15 and the support portion 12 are continuous in the orthogonal direction. The bending portion 15 has a shorter length in the short direction toward the other end side in the orthogonal direction. As shown in FIG. 3, the bending portion 15 has the thickest end portion (left end portion in FIG. 3) connected to the support portion 12 on the other end (right end in FIG. 3) side in the orthogonal direction. It gets thinner as you go. Therefore, the upper surface of the bending portion 15 is curved so as to be positioned downward from the one end to the other end side in the orthogonal direction. As shown in FIG. 4, in the short direction of the pad 30, the length of the support portion 12 and the length of the one end portion of the bending portion 15 are substantially the same. The bending portion 15 has the thickest central portion in the short direction of the pad 30 and is thinner toward both ends. For this reason, the upper surface of the bending portion 15 is curved so as to be positioned downward toward both ends in the lateral direction of the pad 30. As described above, in the orthogonal direction, the one end connected to the support portion 12 is thicker. Therefore, in the entire bending portion 15, the central portion P <b> 1 in the short direction at one end connected to the support portion 12 is the thickest. In the central portion P1, the height is substantially the same as the height of the upper surface of the support portion 12.

  FIG. 5 is a diagram showing a state when the vehicle pedal device is assembled to the vehicle. As shown in FIG. 5, in this state, a bolt 70 is inserted into the bolt hole 14 of the base 10, and the bolt 70 is fastened to a nut 71 fixed to the vehicle. The housing 40 is fixed to the vehicle via bolts and nuts (not shown). The pedestal 10 is arranged so that the orthogonal direction is the same as the vehicle front-rear direction. The hinge portion 20 extends in the short direction of the pad 30, that is, the vehicle width direction, and the pad 30 is disposed so as to be rotatable in the vehicle front-rear direction with the hinge portion 20 as a rotation center. When the driver does not depress the pad 30, the pad 30 and the rod 50 are arranged at predetermined positions on the rear side of the vehicle (right side in FIG. 5) by the urging force of the spring 44 provided in the housing 40. When the driver depresses the pad 30, the pad 30 and the rod 50 in a predetermined position respectively rotate forward of the vehicle (leftward in FIG. 5) against the urging force of the spring 44. Since the rotation center of the rod 50 is the rotation shaft 42 and the rotation center of the pad 30 is the hinge part 20, the trajectories when the rod 50 and the pad 30 rotate are different. A holding portion 60 having a through hole 61 penetrating in the short direction of the pad 30 is provided on the back surface 30 </ b> A of the pad 30, and the insertion portion 51 of the rod 50 is inserted through the holding portion 60. The part 51 is disposed on the back surface 30 </ b> A of the pad 30. When the pad 30 and the rod 50 are rotated in accordance with the stepping operation by the driver, the insertion portion 51 of the rod 50 slides upward in the through hole 61 along the longitudinal direction of the pad 30. When the stepping force by the driver increases and the amount of rotation of the pad 30 and the rod 50 increases, the rod 50 comes into contact with the vehicle and further rotation is restricted, as indicated by a two-dot chain line in FIG. The As described above, when the pad 30 rotates forward of the vehicle, the gap between the back surface 30A of the pad 30 and the upper surface of the base 10 becomes narrower. Further, the angle formed by the virtual plane X including the front surface 26 of the hinge portion 20 and the virtual plane Y including the upper surface of the locking portion 21 is small. When the stepping operation by the driver is released, the pad 30 and the rod 50 are rotated rearward by the biasing force of the spring 44 described above. When the rod 50 comes into contact with the wall surface of the box portion 41 of the housing 40, the rotation of the rod 50 and the pad 30 is stopped and held at the predetermined position described above. The rotation angle sensor 43 detects the rotation angle of the rotation shaft 42 connected to the upper end portion of the rod 50 and outputs a signal corresponding to the rotation angle. For example, the vehicle control device detects the amount of rotation of the pad 30, that is, the operation amount of the vehicle pedal device, based on a signal input from the rotation angle sensor 43, and executes various controls in the vehicle.

With reference to FIG.6 and FIG.7, the effect of this embodiment is demonstrated.
(1) As shown in FIG. 6, a space is formed between the upper surface of the base 10 and the back surface 30 </ b> A of the pad 30, and foreign matter enters between the upper surface of the base 10 and the back surface 30 </ b> A of the pad 30. There is. In the present embodiment, since the curved portion 15 having the above-described configuration is provided in the portion of the pedestal 10 on the back surface 30A side of the pad 30, foreign matter that has entered between the pedestal 10 and the pad 30 is shown in FIG. As indicated by the arrow, it slides outward along the shape of the curved portion 15. If foreign matter remains on the bending portion 15, when the pad 30 is stepped on, the foreign matter is pushed outward by cooperation between the back surface 30 </ b> A of the pad 30 and the upper surface of the bending portion 15. . Therefore, it can suppress that a foreign material is pinched between the pad 30 and the base 10.

  (2) As shown by a two-dot chain line in FIG. 7, the upper surface of the locking portion 21 in the hinge portion 20 is planar, unlike the curved portion 15, and therefore between the locking portion 21 and the coupling portion 25. If foreign matter enters, there is a possibility that the foreign matter may remain on the upper surface of the locking portion 21. In the present embodiment, the front surface 26 of the coupling portion 25 is inclined with respect to the upper surface of the locking portion 21 by a predetermined angle θ so as to be positioned higher as it is farther from the hinge 24, and therefore, is indicated by a solid line in FIG. As described above, when the pad 30 is stepped on and the pad 30 is rotated forward of the vehicle (rightward in FIG. 7), the foreign object 100 is pushed out toward the curved portion 15 by the front surface 26 of the coupling portion 25. The foreign object 100 thus pushed out slides toward the outside of the base 10 along the curved portion 15. Therefore, when the pad 30 is depressed, it is possible to prevent foreign matter from being caught between the locking portion 21 and the coupling portion 25 in the hinge portion 20.

  (3) When the pad 30 is rotated by the driver's stepping operation at the predetermined angle θ, the virtual plane X including the front surface 26 and the virtual plane Y including the upper surface of the locking portion 21 are parallel to each other. It is set not to become. Therefore, the effect of pushing out the foreign material 100 can be obtained over the entire rotation range of the pad 30, and the foreign material 100 can be easily pushed out to the curved portion 15.

In addition, the said embodiment can be changed and implemented as follows. Also, the following modifications can be implemented in combination with each other as appropriate.
-The structure of the base 10 is not restricted to what was mentioned above. For example, you may change as shown in FIG.

  As shown in FIG. 8, the pedestal 80 is provided with a plate-like fixing plate 81. The fixed plate 81 has a rectangular upper surface, and is arranged so that the longitudinal direction thereof is the same as the short direction of the pad 30. The fixed plate 81 is provided with a substantially rectangular parallelepiped support portion 82 that protrudes upward from the upper surface of the fixed plate 81 and supports the hinge portion 20. The fixing plate 81 is provided with bolt holes 83 at both ends in the longitudinal direction so as to sandwich the support portion 82. A curved portion 84 is connected to the fixed plate 81. The curved portion 84 is located on the back surface 30 </ b> A side of the pad 30 with respect to the support portion 82. One end portion of the curved portion 84 connected to the fixed plate 81 has a thicker central portion in the short direction of the pad 30 than the fixed plate 81, and a portion located above the fixed plate 81 is thicker. It is connected to the support part 82. The curved portion 84 has the thickest central portion in the short direction, and is thinner toward both ends. The bending portion 84 is thickest at one end connected to the support portion 82 and the fixing plate 81 in the orthogonal direction perpendicular to the short direction, and is thinner toward the other end. The bending portion 84 has a shorter length in the lateral direction toward the other end side. Even in the curved portion 84 having such a configuration, the upper surface of the curved portion 84 is positioned so as to be lower toward the both ends in the lateral direction, and from one end connected to the support portion 82 and the fixing plate 81 in the orthogonal direction. It is curving so that it may be located below, so that it goes to the other end side. Therefore, even with this configuration, it is possible to prevent foreign matter from being caught between the pad 30 and the base 80.

  -The bending parts 15 and 84 can change suitably the length in the transversal direction of the pad 30, and the length in the said orthogonal direction. For example, the length of the curved portions 15 and 84 in the short direction may be shorter or longer than the length of the support portions 12 and 82 in the same direction. Further, the length of the bending portion 15 in the orthogonal direction is made longer than that of the example shown in FIGS. 3 and 6 so that the other end of the bending portion 15 is located at the same position as the edge of the base 10. Alternatively, it may be protruded from the base 10.

  -The thickness of the bending parts 15 and 84 can be changed suitably. For example, the curved portions 15 and 84 may be thickened so long as the rotation of the pad 30 is not hindered, and the upper surfaces thereof may be positioned above the upper surfaces of the support portions 12 and 82.

  The case where the virtual plane X including the front surface 26 of the hinge portion 20 and the virtual plane Y including the upper surface of the locking portion 21 are parallel to each other when the pad 30 is rotated by a stepping operation by the driver is included. The predetermined angle θ may be set as described above.

  The first connection surface 27 </ b> A in the coupling portion 25 of the hinge portion 20 may be inclined with respect to the upper surface of the locking portion 21 such that the first connection surface 27 </ b> A is positioned higher as the distance from the hinge 24 increases. Moreover, you may incline so that it may approach the upper surface of the latching | locking part 21, so that it leaves | separates from the hinge 24. FIG. Further, the front surface 26 may be constituted by a third connection surface extending substantially parallel to the upper surface of the locking portion 21 and a fourth connection surface extending downward from the back surface 30A of the pad 30 along the back surface 30A.

  -When the hinge part 20 is seen from the side, the coupling | bond part 25 may be comprised from two surfaces instead of three surfaces, and may be comprised from four or more surfaces. Further, the coupling portion 25 may be omitted, and the upper end of the hinge 24 may be directly connected to the lower end portion of the pad 30.

-The latching piece 23 of the hinge part 20 is omissible.
-The thickest part in the short direction of the pad 30 of the curved part 15 may not be the central part in the short direction but may be a part shifted from the central part in the short direction toward one end. The thickest portion in the orthogonal direction may extend a predetermined length in the orthogonal direction.

The holding unit 60 may be omitted. For example, if the insertion part 51 of the rod 50 can be slidably maintained along the back surface 30 </ b> A of the pad 30, it is not necessary to provide the holding part 60.
Although the rod 50 is brought into contact with the vehicle to restrict the rotation range of the pad 30 toward the front of the vehicle, the restriction mode of the rotation range of the pad 30 may be changed. For example, the rotation range of the pad 30 may be regulated by bringing the upper end portion of the rod 50 into contact with the wall surface of the box portion 41 of the housing 40.

  The rod 50 and the pad 30 are urged toward the rear of the vehicle by the spring 44 disposed in the housing 40, but this configuration can be changed as appropriate. For example, a spring may be provided between the vehicle and the rod 50, or a spring that urges the rotating shaft 42 to rotate counterclockwise in FIG. Moreover, you may employ | adopt another elastic member instead of a spring.

  -Housing 40 and rod 50 may be omitted. For example, when a measurement mechanism including a sensor that directly measures the amount of rotation of the pad 30 and a biasing member that biases the pad 30 toward the rear of the vehicle is provided, the housing 40 and the rod 50 can be omitted.
