  A through-hole through which one end 201 of the shaft 20 is inserted is formed in the bearing portion 13. One end 201 of the shaft 20 is rotatably provided in the through hole. That is, the inner wall that forms the through hole becomes the bearing 130 of one end 201 of the shaft 20.

  Mounting portions 131, 132, and 133 are formed in the housing 12. Bolt holes are formed in the attachment portions 131, 132, 133, respectively. The accelerator device 1 is attached to the vehicle body 5 by a bolt (not shown) inserted through the bolt hole.

  A concave fully open stopper portion 19 is formed on the ground side of the back surface portion 15. When the fully open stopper 19 abuts on a convex fully open stopper 31 provided on the operation member 30, the rotation angle of the operation member 30 is restricted at the accelerator fully open position. The accelerator fully open position is a position that is set such that the degree of depression of the operation member 30 by the driver, that is, the accelerator opening is 100%.

The first cover 16 and the second cover 18 are provided to face the bearing portion 13.
The first cover 16 is a resin member that is locked to the second cover 18 so as to come into contact with the end of the upper surface portion 14, the back surface portion 15, and the front surface portion 17 opposite to the side connected to the bearing portion 13. It is. The first cover 16 prevents foreign matter from entering the internal space 11.
The second cover 18 is a resin member that is fixed by bolts to the opposite end portions connected to the bearing portions 13 of the back surface portion 15 and the front surface portion 17. A bottomed hole that rotatably supports the other end 202 of the shaft 20 is formed in the inner wall of the second cover 18. That is, the inner wall forming the bottomed hole becomes the bearing 180 of the other end 202 of the shaft 20. The second cover 18 prevents foreign matter from entering the internal space 11.

  The shaft 20 is provided in the horizontal direction on the ground side of the accelerator device 1. One end 201 of the shaft 20 is formed with a sensor accommodation hole 22 that accommodates Hall elements 631 and 632 as “magnetic detection portions” of the rotation angle detection portion 60. A yoke 221 and magnets 222 and 223 are provided on the inner wall of the sensor housing hole 22.

The magnets 222 and 223 are disposed so as to face each other with the rotation axis φ <b> 1 of the shaft 20 in the radially inward direction of the yoke 221, and are fixed to the inner wall of the yoke 221.

  The shaft 20 rotates in a predetermined angular range from the accelerator fully closed position to the accelerator fully open position in accordance with the torque transmitted from the operation member 30 as the driver depresses. The accelerator fully closed position is a position set so that the degree of depression of the operation member 30 by the driver, that is, the accelerator opening is 0%.

  Hereinafter, the rotation direction of the operating member 30 from the accelerator fully closed position shown in FIG. 3 toward the accelerator fully open position will be referred to as “accelerator open direction”. Further, the rotation direction of the operating member 30 from the accelerator fully open position toward the accelerator fully closed position is described as “accelerator close direction”.

  The operating member 30 includes a rotating body 38, a pedal 28, a pedal arm 26, and the like, in which a pedal boss portion 32, an arm connecting portion 34, a spring receiving portion 35, and a fully closed stopper portion 36 are integrally formed.

  The pedal boss portion 32 is formed in an annular shape, is provided between the bearing portion 13 and the second cover 18, and is fixed to the outer wall of the shaft 20 by, for example, press fitting.

  A first helical tooth 321 is integrally formed on the side surface of the pedal boss portion 32 on the second cover 18 side. A plurality of first helical teeth 321 are formed at equal intervals in the circumferential direction. The first helical tooth 321 has an inclined surface that protrudes toward the rotor 54 side of the hysteresis mechanism unit 50 in the circumferential direction in the accelerator closing direction and approaches the rotor 54 in the tip end portion in the accelerator closing direction.

  A first friction member 323 is provided on the side surface of the pedal boss portion 32 on the housing 12 side. The first friction member 323 is formed in an annular shape and is provided between the pedal boss portion 32 and the inner wall of the bearing portion 13 in the radially outward direction of the shaft 20. When the pedal boss portion 32 is pushed away from the rotor 54, that is, in the direction of the bearing portion 13, the pedal boss portion 32 is frictionally engaged with the first friction member 323. The frictional force between the pedal boss part 32 and the first friction member 323 becomes the rotational resistance of the pedal boss part 32.

  The arm connecting portion 34 is formed such that one end is connected to the radially outer side surface of the pedal boss portion 32 and the other end extends to the outside of the support member 10 through the communication hole 111.

  The fully closed stopper portion 36 is formed so as to extend from the spring receiving portion 35 in the ceiling direction in the internal space 11. When the fully closed stopper portion 36 abuts against the inner wall of the back surface portion 15, the rotation of the pedal 28 in the accelerator closing direction is restricted at the accelerator fully closed position.

  The spring receiving portion 35 is formed in a convex shape on the front portion 17 side of the fully closed stopper portion 36 extending from the pedal boss portion 32. The spring receiving portion 35 engages one end of the return spring 39.

The pedal arm 26 is formed in a substantially rod shape from metal, and one end portion is fixed to the arm connecting portion 34 as shown in FIGS. The other end of the pedal arm 26 is connected to the pedal 28. The pedal arm 26 has a function of adjusting the position of the pedal 28 with respect to the support member 10.
The operating member 30 converts the pedaling force of the driver when the pedal 28 is depressed into a rotational torque centered on the rotational axis φ1 of the shaft 20 and transmits the rotational torque to the shaft 20 via the rotating body 38.

  When the pedal 28 rotates in the accelerator opening direction, the rotation angle of the shaft 20 in the accelerator opening direction with the accelerator fully closed position as a base point increases, and the accelerator opening corresponding to this rotation angle increases. Further, when the pedal 28 rotates in the accelerator closing direction, the rotation angle of the shaft 20 decreases, and the accelerator opening decreases.

  The return spring 39 is composed of a coil spring. The return spring 39 biases the operation member 30 in the accelerator closing direction. The urging force that the return spring 39 acts on the operation member 30 increases as the rotation angle of the operation member 30, that is, the rotation angle of the shaft 20 increases. The urging force is set so that the operating member 30 and the shaft 20 can be returned to the accelerator fully closed position regardless of the rotational position of the operating member 30. The return spring 39 corresponds to a “biasing member” recited in the claims.

  The rotation angle detection unit 60 is provided on the outer wall of the housing 12. At this time, the two Hall elements 631 and 632 included in the rotation angle detection unit 60 are accommodated in the sensor accommodation hole 22 of the shaft 20. The detailed structure of the rotation angle detector 60 will be described later.

  The hysteresis mechanism 50 includes a rotor 54, a second friction member 58, a hysteresis spring 59, and the like.

  The rotor 54 is provided between the pedal boss portion 32 and the inner wall of the second cover 18 in the radially outward direction of the shaft 20. The rotor 54 is formed in an annular shape, can rotate relative to the shaft 20 and the pedal boss portion 32, and can approach or separate from the pedal boss portion 32. A second helical tooth 541 is integrally formed on the side surface of the rotor 54 on the pedal boss portion 32 side. A plurality of second helical teeth 541 are formed at equal intervals in the circumferential direction. The second helical tooth 541 has an inclined surface that protrudes toward the pedal boss portion 32 toward the accelerator opening direction in the circumferential direction and approaches the rotor 54 toward the tip end portion in the accelerator opening direction.

  The first helical teeth 321 and the second helical teeth 541 have inclined surfaces in contact with each other in the circumferential direction, and can transmit rotation between the pedal boss portion 32 and the rotor 54. That is, the rotation of the pedal boss portion 32 in the accelerator opening direction can be transmitted to the rotor 54 via the first helical teeth 321 and the second helical teeth 541. The rotation of the rotor 54 in the accelerator closing direction can be transmitted to the pedal boss portion 32 via the second helical teeth 541 and the first helical teeth 321.

  Further, when the rotation position of the pedal boss portion 32 is closer to the accelerator fully open position than the accelerator fully closed position, the first helical teeth 321 and the second helical teeth 541 engage with each other so that the inclined surfaces engage with each other. 54 are separated from each other. At this time, the first helical teeth 321 push the pedal boss portion 32 toward the housing 12 with a greater force as the rotation angle of the pedal boss portion 32 from the accelerator fully closed position increases. Further, the second helical tooth 541 pushes the rotor 54 toward the second cover 18 with a larger force as the rotation angle of the pedal boss portion 32 from the accelerator fully closed position increases.

  The second friction member 58 is formed in an annular shape and is provided between the rotor 54 and the inner wall of the second cover 18 in the radially outward direction of the shaft 20. When the rotor 54 is pushed away from the pedal boss portion 32, that is, in the direction of the second cover 18, the rotor 54 frictionally engages with the second friction member 58. The frictional force between the rotor 54 and the second friction member 58 becomes the rotational resistance of the rotor 54.

  The hysteresis spring 59 is constituted by a coil spring. One end of the hysteresis spring 59 is locked to a locking portion 52 formed on the top side of the rotor 54. Further, the other end of the hysteresis spring 59 is locked to the inner wall of the front portion 17. The hysteresis spring 59 urges the rotor 54 in the accelerator closing direction. The biasing force of the hysteresis spring 59 increases as the rotation angle of the rotor 54 increases. Torque received by the rotor 54 by the biasing force of the hysteresis spring 59 is transmitted to the pedal boss portion 32 via the second helical teeth 541 and the first helical teeth 321.

  Next, a detailed configuration of the rotation angle detection unit 60 will be described with reference to FIG. In FIG. 4B, the position of the shaft 20 with respect to the rotation angle detection unit 60 when the rotation angle detection unit 60 is assembled to the support member 10 is indicated by a dotted line.

  Two Hall elements 631 and 632 are mounted on a base portion 64 that is a substantially flat metal member, and are provided in an end portion 651 from which a mold portion 65 to be described later projects. The Hall elements 631 and 632 are provided in a magnetic field formed by the magnets 222 and 223 when the rotation angle detection unit 60 is assembled to the bearing unit 13 of the housing 12. When the shaft 20 rotates, an electromotive force is generated in the Hall elements 631 and 632 through which a current flows. The magnitude of the electromotive force generated is proportional to the rate of change of the magnetic flux density that passes through the Hall elements 631 and 632. The magnetic flux density penetrating through the Hall elements 631 and 632 changes when the magnets 222 and 223 rotate around the rotation axis φ1 together with the shaft 20. The hall elements 631 and 632 output an electrical signal corresponding to the rotation angle to the terminal 66 via the base portion 64.

  The mold part 65 is formed of a resin material and is provided so as to cover the base part 64 on which the Hall elements 631 and 632 are mounted. An end portion of the base portion 64 protruding from the mold portion 65 is electrically connected to the terminal 66.

The other ends 691, 692, 693, 694, 695, and 696 correspond to the “output end of the terminal” recited in the claims.

  The insert portion 68 is a resin member formed by inserting the detection member 67 and the terminal 66. The insert portion 68 is formed in a substantially L shape so as to follow the shape of the support member 10 of the accelerator device 1. The insert part 68 includes a detection part 681, a first extension part 61, a second extension part 62, a connector part 69, and the like, which are integrally formed.

  The detection unit 681 is a substantially cylindrical resin part. The detection unit 681 is formed thicker than the first extending unit 61 connected to the detection unit 681. A detection member 67 and a part of the terminal 66 are inserted into the detection unit 681.

  The 1st extending | stretching part 61 is a substantially flat resin-made site | part. The first extending portion 61 is connected to the outside in the radial direction of the detecting portion 681. The first extending portion 61 is formed to extend in the vertical direction along the outer wall 134 (see FIG. 2) as the “first side wall” of the bearing portion 13 when the rotation angle detecting portion 60 is assembled to the support member 10. Yes. That is, the first extending portion 61 is formed to be perpendicular to the rotation axis φ1 of the shaft 20. The term “vertical” as used herein is not limited to “vertical” in a strict sense, but can be recognized by those skilled in the art as “vertical” in the manufacturing process of the accelerator device 1 including the resin molding process of the insert portion 68. Including some degree of “vertical”. One end side of the metal wires 661, 662, 663, 664, 665, and 666 included in the terminal 66 is inserted into the first extending portion 61.

  The second extending portion 62 is a substantially flat resin portion. The second extending part 62 is connected to the end of the first extending part 61 opposite to the side connected to the detecting part 681. The second extending portion 62 is formed so as to extend in the horizontal direction along the outer wall 141 (see FIGS. 1 and 3) as the “second side wall” of the upper surface portion 14 when the rotation angle detection unit 60 is assembled to the support member 10. Has been. That is, the second extending portion 62 is formed so as to be connected perpendicularly to the first extending portion 61 and to be parallel to the rotation axis φ1 of the shaft 20. The term “parallel” as used herein is not limited to “parallel” in the strict sense, but can be recognized by those skilled in the art as “parallel” in the manufacturing process of the accelerator device 1 including the resin molding process of the insert portion 68. Including some degree of “parallel”. The other ends 691, 692, 693, 694, 695, and 696 of metal wires 661, 662, 663, 664, 665, and 666 included in the terminal 66 are inserted into the second extending portion 62.

  The connector part 69 is a bottomed cylindrical resin part connected to the top surface 621 of the second extending part 62. In the accelerator device 1 according to the first embodiment, as shown in FIG. 4B, the connector portion 69 is provided at the end of the second extending portion 62 opposite to the side connected to the first extending portion 61. . In the connector portion 69, the other ends 691, 692, 693, 694, 695, and 696 of the terminal 66 are provided so as to be arranged in parallel with the first extending portion 61. That is, the other end portions 691, 692, 693, 694, 695, and 696 are provided so as to be aligned perpendicular to the rotation axis φ 1 of the shaft 20. The connector part 69 fits into a connector included in an external electronic control device.

  The rotation angle detection unit 60 outputs an electrical signal corresponding to the magnitude of the electromotive force generated in the Hall elements 631 and 632 to the external electronic control device via the base unit 64 and the terminal 66. In the external electronic control device, the relative rotation angle between the Hall elements 631 and 632 and the magnets 222 and 223, that is, the rotation angle of the shaft 20 with respect to the support member 10 is detected based on the input electric signal.

  Next, the operation of the accelerator device 1 will be described.

  When the pedal 28 is depressed, the operation member 30 rotates in the accelerator opening direction around the rotation axis φ <b> 1 together with the shaft 20 in accordance with the depression force applied to the pedal 28. At this time, in order for the operating member 30 and the shaft 20 to rotate, the sum of the torque due to the biasing force of the return spring 39 and the hysteresis spring 59 and the resistance torque due to the frictional force of the first friction member 323 and the second friction member 58 is obtained. The pedaling force that produces a large torque is also required.

  The resistance torque due to the frictional force of the first friction member 323 and the second friction member 58 acts to suppress the rotation of the pedal 28 in the accelerator opening direction when the pedal 28 is depressed. As a result, the pedaling force increases when the pedal 28 is depressed at the same rotation angle as compared with when the pedal 28 is depressed.

  In order to maintain the depression of the pedal 28 after the pedal 28 is depressed, the torque generated by the biasing force of the return spring 39 and the hysteresis spring 59 and the resistance torque generated by the frictional force of the first friction member 323 and the second friction member 58 are calculated. What is necessary is just to add the treading force which produces a torque larger than a difference. That is, when the driver wants to maintain the depression of the pedal 28 after depressing the pedal 28, the driver may relax the pedaling force somewhat. The resistance torque due to the frictional force of the first friction member 323 and the second friction member 58 acts to suppress the rotation of the pedal 28 in the accelerator closing direction when the pedal 28 is kept depressed.

  In order to return the depression of the pedal 28 to the accelerator fully closed position side, the difference between the torque due to the urging force of the return spring 39 and the hysteresis spring 59 and the resistance torque due to the frictional force of the first friction member 323 and the second friction member 58 is obtained. Will also add a pedal force that produces a small torque. Here, in order to quickly return the pedal 28 to the accelerator fully closed position, it is only necessary to stop the depression of the pedal 28, so that the driver is not burdened. That is, the burden on the driver when returning the pedal 28 is reduced. The resistance torque caused by the frictional force of the first friction member 323 and the second friction member 58 acts to suppress the rotation of the pedal 28 in the accelerator closing direction when the pedal 28 is returned to the depressed position.

  In the accelerator apparatus 1 according to the first embodiment, the rotation angle detector 60 is provided with a second extending portion 62 that extends in the horizontal direction along the outer wall 141 of the upper surface portion 14. The second extending portion 62 has a cross-sectional area that can insert the metal wires 661, 662, 663, 664, 665, 666 of the terminal 66. The connector portion 69 that accommodates the other ends 691, 692, 693, 694, 695, and 696 of the terminal 66 is provided at any position on the top surface 621 of the second extending portion 62.

  Specifically, by preparing a plurality of insert part molds for resin molding the insert part 68, the connector part 69 is connected to the first extension part 61 of the second extension part 62 as shown in FIG. Or provided at the end opposite to the side to be connected to the end, or as shown in FIG. 5, at the end of the second extension 62 connected to the first extension 61 or substantially at the center of the second extension 62. Can be provided. As described above, in the accelerator apparatus 1 according to the first embodiment, the connector part 69 with respect to the support member 10 is horizontally provided by preparing a plurality of relatively inexpensive molds for the insert part in accordance with the position where the connector part 69 is provided. It can be changed to the position of the direction. Accordingly, the accelerator device 1 can be attached to the vehicle body 5 so as to provide the pedal 28 at a position suitable for the driver without being affected by the connection position between the vehicle side and the connector portion 69. Therefore, the degree of freedom of the mounting position of the support member 10 with respect to the vehicle body 5 can be improved according to the position of the pedal 28 and a connection portion (not shown) on the side connected to the connector portion 69.

  Further, since a plurality of relatively inexpensive insert molds are prepared in accordance with the position of the connector portion 69, the degree of freedom of the mounting position of the support member 10 with respect to the vehicle body 5 is improved. The pedal 28 can be provided at a position suitable for the driver without changing the shape of the pedal arm 26 to be connected. As a result, it is possible to reduce the types of pedal arms that are molded from a relatively expensive mold and are provided with the pedals 28 at positions suitable for the driver. Therefore, the accelerator device 1 according to the first embodiment can reduce the manufacturing cost.

  In the accelerator device 1 according to the first embodiment, the second extending portion 62 is formed along the outer wall 141 of the upper surface portion 14. Thereby, the 2nd extending part 62 will be supported by the support member 10, and the position of the connector part 69 provided in the 2nd extending part 62 can be stabilized.

  The second extending portion 62 is formed to be parallel to the rotation axis φ1 of the shaft 20. By providing the member constituting the accelerator device 1 so as to be parallel to the rotation axis φ1 of the shaft 20 having a relatively long length, the second extending portion 62 can be lengthened. Thereby, the freedom degree of the position in which the connector part 69 is provided can be enlarged further. Therefore, the freedom degree of the attachment position of the support member 10 with respect to the vehicle body 5 can further be improved.

(Second Embodiment)
