Description

  The present invention relates to an accelerator pedal module that includes a pedal lever, a return spring, an accelerator sensor, and a kick-down mechanism and is operated to control engine output.

  Conventionally, as this type of accelerator pedal module, for example, there are those described in Patent Documents 1 and 2 below. The accelerator pedal module detects a pedal lever that is pivotally supported between a rest position (fully closed position) and a terminal position (fully opened position) in the vehicle portion, and a pivot position of the pedal lever. An accelerator sensor, a return spring for returning the pedal lever to the rest position, and a kick-down mechanism for applying a sudden pedaling force to the pedal lever near the end position (kick-down position) of the pedal lever are provided.

  Here, in the accelerator pedal module described in Patent Document 1, the electric signal of the accelerator sensor can be adjusted at one rotation position of the pedal lever. As shown in FIG. 15, first, an electrical signal (output voltage) supplied from the accelerator sensor at the rest position of the pedal lever corresponds to a first electrical adjustment signal that can be set in advance. Thus, the position of the accelerator sensor can be adjusted (position adjustment (1)). Next, at the kick-down position, the kick-down position of the pedal lever can be adjusted so that the electrical signal (output voltage) supplied from the accelerator sensor corresponds to a second electrical adjustment signal that can be set in advance. (Position adjustment (2)).

  On the other hand, in the accelerator pedal module described in Patent Literature 2, the electric signal of the accelerator sensor can be adjusted at one rotation position of the pedal lever. Then, as shown in FIG. 16, first, at the kick-down position of the pedal lever, the electrical signal (output voltage) supplied from the accelerator sensor is equivalent to a first electrical adjustment signal that can be set in advance. In addition, the position of the accelerator sensor can be adjusted (position adjustment (1)). Next, at the rest position, the rest position of the pedal lever can be adjusted so that the electrical signal (output voltage) supplied from the accelerator sensor corresponds to a second electrical adjustment signal that can be set in advance. (Position adjustment (2)).

  Moreover, as a kick down mechanism used for an accelerator pedal module, there exists a thing described in the following patent document 3, for example. This kick-down mechanism provides tactile feedback to the foot when the driver depresses the pedal of the vehicle, and includes a case and a plunger with a recess. The plunger moves linearly in conjunction with the movement of the pedal. The friction generating assembly held in the case includes a rod held in the case. The rod tilts in the direction of the indentation of the plunger, and when the pedal is depressed, the plunger is pushed from a first position where the rod is located in the indentation to a second position out of the indentation. According to this kick down mechanism, as shown in FIG. 17, when the stroke to the end position (fully open position) (end position stroke) is small, the output from the accelerator pedal module (pedal position sensor) at the kick down position is It must exist in the first range E1 in FIG. When the end position stroke is large, the output from the pedal position sensor at the kick down position must be in the second range E2 in FIG.

For this reason, the position of the output of the pedal position sensor (kickdown output) at the time of kickdown has to be adjusted with high accuracy. Here, if the adjustment of the kickdown output is eliminated or a sufficient adjustment margin is secured, the stroke from the kickdown position to the end position becomes large.

[First Embodiment]
Hereinafter, a first embodiment of an accelerator pedal module according to the present invention will be described in detail with reference to the drawings.

  The accelerator pedal module 1 of this embodiment is shown in a side view in FIGS. 2 and 4 are side views showing the main internal structure of the module 1.

  In this embodiment, the accelerator pedal module 1 is provided in the driver's seat of the vehicle and is operated to control the output of the vehicle engine. As shown in FIG. 1, the accelerator pedal module 1 includes a pedal lever 2 having an accelerator pedal 2a at the tip, a pedal lever 2, a rest position PR indicated by a solid line in FIGS. 1 and 2, and a two-dot chain line in FIG. 3 and 4, a support frame 3 that is rotatably supported with respect to a terminal position PE indicated by a solid line, and an accelerator sensor 4 for detecting the rotational position of the pedal lever 2 are provided. The pedal lever 2 and the support frame 3 are made of synthetic resin.

  2 and 4, the accelerator pedal module 1 includes a pair of return springs 5A and 5B for returning the pedal lever 2 to the rest position PR, and a kick-down position PK in the vicinity of the end position PE (see FIG. 1). And a kick-down mechanism 6 for applying a sudden pedaling force to the pedal lever 2.

  The pedal lever 2 is rotatably supported by the support frame 3 via the support shaft 7. The support frame 3 includes an opening 3 a that allows the pedal lever 2 to rotate. As shown in FIG. 2, when the pedal lever 2 is engaged with the upper edge of the opening 3a, the rest position PR of the pedal lever 2 is determined. The return springs 5 </ b> A and 5 </ b> B include a seat portion 2 c provided on the base end portion (lever base end portion) 2 b of the pedal lever 2 and a seat portion 3 b provided on the inner side of the support frame 3. It intervenes between. The kick down mechanism 6 is assembled in a fitting groove 3 c provided inside the support frame 3.

  The accelerator pedal 2a is provided so that it can be depressed between the rest position PR and the end position PE. That is, the support frame 3 includes the lever base end portion 2b and supports the base end portion 2b through the support shaft 7 so as to be rotatable, whereby the pedal lever 2 together with the accelerator pedal 2a is shown in FIGS. Is operable between a rest position (fully closed position) PR indicated by a solid line and a terminal position (fully opened position) PE indicated by a two-dot chain line in FIG. 1 and a solid line in FIGS. The return springs 5A and 5B, which are a pair of large and small, urge the pedal lever 2 in the return direction in order to return the accelerator pedal 2a to the rest position PR. The reason why a pair of return springs 5A and 5B is provided is that when one of them becomes ineffective, the other functions as a fail-safe.

  A pedal stopper 2d extending downward is integrally formed on the lower side of the accelerator pedal 2a. The pedal stopper 2d protects the accelerator pedal module 1 by striking against the floor when the accelerator pedal 2a is further depressed from the end position PE.

  As shown in FIGS. 1 and 3, the accelerator sensor 4 is provided in a sensor case 8 formed integrally with the support frame 3. A connector 9 including a wiring terminal is provided in the upper part of the support frame 3. 1 and 3, the sensor case 8 shows a state where a cover (not shown) is removed. The accelerator sensor 4 includes a sensor lever 10 that rotates about a support shaft 7, a brush 11 provided on the lever 10 (the back surface of the brush 11 is shown in FIGS. 1 and 3), and the brush 11. Correspondingly disposed substrates 12. The substrate 12 is provided with a resistor 13 that is in contact with the brush 11 and an output circuit that outputs a signal corresponding to the rotation amount of the sensor lever 10 as an accelerator opening. The resistor 13 is formed on the substrate 12 by printing in a strip shape. In this embodiment, the resistor 13 corresponds to the output adjusting means of the present invention. In order to adjust the output of the accelerator sensor 4, a part of the resistor 13 is trimmed with leather.

  Therefore, when the accelerator pedal 2 a is depressed, the pedal lever 2 rotates about the support shaft 7 and the sensor lever 10 rotates about the support shaft 7. The rotation of the sensor lever 10 is replaced by the movement of the brush 11 with respect to the resistor 13, and the rotation amount is output from the substrate 12 as a voltage corresponding to the accelerator opening.

  The kick-down mechanism 6 will be described with reference to FIGS. FIG. 5 shows a side sectional view of the kick down mechanism 6, FIG. 6 shows a front view of the kick down mechanism 6, and FIG. 7 shows a side sectional view of the kick down mechanism 6. The kickdown mechanism 6 includes a case 21 having a rectangular parallelepiped shape, a cylinder 21a provided in the case 21, a plunger 22 incorporated in the cylinder 21a, and a book for locking the plunger 22 so that it can deviate at a fixed position. A pin 23 and a first spring 24 corresponding to the locking means of the present invention, and a second spring 25 corresponding to the biasing means of the present invention for biasing the plunger 22 toward a fixed position are provided. The plunger 22 includes a circumferential groove 22a on the outer periphery thereof. As the pin 23 engages with the circumferential groove 22a, the plunger 22 is locked in place. In this embodiment, an adjustment bolt 26 corresponding to the terminal position adjusting means of the present invention for adjusting the terminal position PE of the pedal lever 2 is provided integrally with the kick-down mechanism 6. The adjustment bolt 26 is incorporated in the screw hole 21 b of the case 21. A third spring 27 is provided between the head 26 a of the adjustment bolt 26 and the case 21 to suppress loosening of the bolt 26. The adjusting bolt 26 is disposed along the center of the cylinder 21a. The tip of the adjustment bolt 26 is provided so as to be able to contact the plunger 22. By adjusting the screwing amount of the adjustment bolt 26 into the screw hole 21b, the tip position of the bolt 26 is adjusted. Thereby, the movement of the plunger 22 which deviates from a fixed position is controlled so that position adjustment is possible.

  As shown in FIGS. 2 and 4, a protrusion 2 e is integrally formed on the lever base end 2 b corresponding to the plunger 22 of the kick-down mechanism 6. Then, when the pedal lever 2 reaches the kick-down position PK, the protrusion 2e pushes the plunger 22.

  Accordingly, when the accelerator pedal 2a is depressed and the pedal lever 2 reaches the kick-down position PK, the protrusion 2e of the lever 2 contacts the plunger 22. Further, when the pedal lever 2 rotates toward the end position PE, the plunger 22 is pushed by the protrusion 2e as shown in FIG. As a result, the plunger 22 deviates from the pin 23 against the urging force of the first spring 24 and moves until it abuts against the tip of the adjustment bolt 26 against the urging force of the second spring 25. When the plunger 22 comes into contact with the tip of the adjustment bolt 26 and the movement is restricted, the pedal lever 2 is restricted from rotating at the end position PE.

  Next, a function adjustment method related to the pedal stroke of the pedal lever 2 and the output of the accelerator sensor 4 will be described for the accelerator pedal module 1 described above. FIGS. 8A and 8B are graphs showing the relationship between the output voltage of the accelerator sensor 4 and the pedaling force with respect to the pedal stroke.

  As a function adjusting method, first, in the first procedure, as shown in FIG. 4, the pedal lever 2 is arranged at the end position PE. At this time, the plunger 22 of the kick-down mechanism 6 is pushed by the protrusion 2e of the pedal lever 2, and the plunger 22 comes into contact with the tip of the adjustment bolt 26.

  Thereafter, in the second procedure, the pedal stroke is adjusted to a predetermined value (position adjustment (1)) as shown in FIG. 8B in a state where the pedal lever 2 is disposed at the terminal position. In this adjustment, while the rotation angle of the pedal lever 2 from the rest position PR is measured by the angle sensor as a pedal stroke, the screwing amount of the adjustment bolt 26 into the screw hole 21b is adjusted so that the measured value becomes a predetermined value. Is done.

  Finally, in the third procedure, the output of the accelerator sensor 4 is adjusted to a predetermined value with the pedal stroke adjusted. This adjustment is performed by changing the resistance value of the resistor 13 by performing laser trimming 28 on the resistor 13 of the substrate 12 as shown in FIG. By changing the resistance value, the output voltage of the accelerator sensor 4 is adjusted to a predetermined value. This output adjustment is performed in anticipation of an output change of the accelerator sensor 4 up to the kick-down position PK so that a predetermined output voltage is obtained at the kick-down position PK. That is, the output voltage is adjusted so that the output voltage (electrical adjustment signal) at the kick-down position is between the kick-down pedal force peak position and the end position PE. In this way, adjustment relating to the pedal stroke and the output of the accelerator sensor 4 is performed.

  According to the configuration of the accelerator pedal module 1 of this embodiment described above, the end position PE of the pedal lever 2 is adjusted by the adjustment bolt 26 so as to be a predetermined pedal stroke from the rest position PR. Then, the output of the accelerator sensor 4 is adjusted to a predetermined value by the laser trimming 28 of the resistor 13 of the substrate 12 in a state where the pedal lever 2 is disposed at the terminal position PE. Accordingly, in the conventional example, the position of the pedal lever is adjusted depending on the output adjustment of the accelerator sensor, whereas in this embodiment, the pedal lever 2 is not dependent on the output adjustment of the accelerator sensor 4. The end position PE itself is adjusted. For this reason, while being able to adjust the output of the accelerator sensor 4 appropriately, the variation in the terminal position PE of the pedal lever 2 can be made relatively small.

  According to the accelerator pedal module 1 of this embodiment, the kick-down mechanism 6 is integrally provided with the adjusting bolt 26 for adjusting the end position. That is, the plunger 22 is incorporated in the cylinder 21a of the case 21 constituting the kick-down mechanism 6, and the adjustment bolt 26 is provided on the cylinder 21a of the case 21 so that the position of the movement of the plunger 22 can be adjusted. Accordingly, since the end position PE adjusted by the adjusting bolt 26 is determined based on the kick-down mechanism 6, the variation in the kick-down position PK of the pedal lever 2 can be relatively reduced. Moreover, the physique of the kick down mechanism 6 and the adjustment bolt 26 can be made compact as a whole.

  According to the accelerator pedal module 1 of this embodiment, the kickdown mechanism 6 including the adjusting bolt 26 is disposed in parallel with the return springs 5A and 5B in the support frame 3 at a position closer to the support shaft 7 than the return springs 5A and 5B. Be placed. Therefore, the kick-down mechanism 6 and the adjusting bolt 26 can be provided by effectively using the dead space in the support frame 3. For this reason, the kick down mechanism 6 and the adjusting bolt 26 do not protrude from the support frame 3, and the accelerator pedal module 1 can be made compact as a whole.

  According to the function adjustment method of the accelerator pedal module 1 of this embodiment, the terminal position PE of the pedal lever 2 is adjusted from the rest position PR to a predetermined pedal stroke by the first and second procedures. Then, after the terminal position PE of the pedal lever 2 is adjusted by the third procedure, the output of the accelerator sensor 4 is adjusted to a predetermined value. Therefore, the terminal position PE of the pedal lever 2 itself is adjusted without depending on the output adjustment of the accelerator sensor 4. Thereby, while being able to adjust the output of the accelerator sensor 4 appropriately, the variation in the terminal position of the pedal lever 2 can be made relatively small.

  According to the function adjustment method of this embodiment, in accordance with the third procedure, the output of the accelerator sensor 4 in the kick-down position PK is anticipated so that the output of the accelerator sensor 4 at the kick-down position PK becomes a predetermined value. The output is adjusted. Therefore, the output of the accelerator sensor 4 related to the end position PE and the kick down position PK is adjusted simultaneously. For this reason, the output adjustment work of the accelerator sensor 4 can be simplified.

[Second Embodiment]
Next, a second embodiment in which the accelerator pedal module of the present invention is embodied will be described in detail with reference to the drawings.

  In this embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Hereinafter, different points will be mainly described. The accelerator pedal module 31 of this embodiment is different in configuration from the accelerator pedal module 1 of the first embodiment in terms of the kick down mechanism 32.

  10 and 11 are side views showing the main internal structure of the accelerator pedal module 31 of this embodiment. FIG. 10 shows a state where the pedal lever 2 is arranged at the rest position PR, and FIG. 11 shows a state where the pedal lever 2 is arranged at the end position PE. In this accelerator pedal module 31, the kick-down mechanism 32 is disposed at substantially the same position as the accelerator pedal module 1 of the first embodiment. The kick down mechanism 32 is assembled in the fitting groove 3 c of the support frame 3.

  The kick-down mechanism 32 will be described with reference to FIGS. 12 is a side sectional view of the kick down mechanism 32, FIG. 13 is a front view of the kick down mechanism 32, and FIGS. 14A and 14B are side sectional views of the kick down mechanism 32. FIG. The kick-down mechanism 32 includes a case 33 having a rectangular parallelepiped shape, a cylinder 33a provided in the case 33, a plunger 34 incorporated in the cylinder 33a, and a book for locking the plunger 34 so that it can deviate at a fixed position. A ball 35 and a first spring 36 corresponding to the locking means of the present invention and a second spring 37 corresponding to the biasing means of the present invention for biasing the plunger 34 toward a fixed position are provided. The plunger 34 has a cylindrical shape and includes a circumferential groove 34a on the outer periphery on the tip side (right side in FIGS. 12 and 14). When the ball 35 is engaged with the circumferential groove 34a, the plunger 34 is locked at a fixed position. In this embodiment, the adjusting bolt 38 included in the terminal position adjusting means of the present invention for adjusting the terminal position PE of the pedal lever 2 is provided integrally with the kick down mechanism 32. The adjustment bolt 38 is incorporated in a screw hole 34 b formed in the plunger 34 along the axial direction on the distal end side of the plunger 34. A third spring 39 is provided between the head 38 a of the adjustment bolt 38 and the tip of the plunger 34 to suppress loosening of the bolt 38. The head 38a of the adjustment bolt 38 is disposed to face the lever base end 2b.

  As shown in FIGS. 10 and 11, the lever base end portion 2 b is provided with a contact portion 2 f that contacts the head portion 38 a of the adjustment bolt 38. When the pedal lever 2 reaches the kick-down position PK, the contact portion 2f pushes the adjustment bolt 38 together with the plunger 34.

  As shown in FIG. 12, the plunger 34 is provided in the cylinder 33 a of the case 33 so as to be movable by the kick down mechanism stroke KS. As shown in FIGS. 14A and 14B, by adjusting the screwing amount of the adjusting bolt 38 into the screw hole 34b, the projecting dimension DA of the head 38a of the bolt 38 with respect to the contact portion 2f is adjusted. Is done. Thereby, the kick down position KP when the plunger 34 begins to deviate from the home position is adjusted. That is, the pedal stroke when the pedal lever 2 comes into contact with the kick-down mechanism 32 is adjusted.

  Accordingly, when the accelerator pedal 2 a is depressed and the pedal lever 2 reaches the kick-down position PK, the contact portion 2 f of the lever 2 contacts the head 38 a of the adjustment bolt 38. Further, when the pedal lever 2 is rotated toward the end position PE, as shown in FIGS. 14A and 14B, the plunger 34 is pushed together with the adjusting bolt 38 by the contact portion 2f. As a result, the plunger 34 deviates from the ball 35 against the urging force of the first spring 36 and moves until it abuts against the bottom surface 33 b of the cylinder 33 a against the urging force of the second spring 37. When the plunger 34 abuts against the bottom surface 33b of the cylinder 33a and the movement is restricted, the pedal lever 2 is restricted from rotating at the end position PE.

  Next, a function adjustment method related to the pedal stroke of the pedal lever 2 and the output of the accelerator sensor 4 will be described for the accelerator pedal module 31 described above.

  As a function adjusting method, first, in the first procedure, as shown in FIG. 11, the pedal lever 2 is arranged at the end position PE. At this time, the adjustment bolt 38 of the kick-down mechanism 32 is pushed by the contact portion 2f of the pedal lever 2, and the plunger 34 is in contact with the bottom surface 33b of the cylinder 33a as shown in FIG.

  Thereafter, in the second procedure, the pedal stroke is adjusted to a predetermined value in a state where the pedal lever 2 is disposed at the terminal position PE. In this adjustment, the angle DA of the head 38a of the adjustment bolt 38 is adjusted so that the measured value becomes a predetermined value while measuring the rotation angle from the rest position PR of the pedal lever 2 as a pedal stroke by the angle sensor. Is done. By this adjustment, the end position PE of the pedal lever 2 itself can be adjusted, and the variation in the end position PE can be relatively reduced.

  Here, as shown in FIG. 12, the stroke from the kick-down position PK to the end position PE is determined by a kick-down mechanism stroke KS set in advance according to the assembly relationship between the cylinder 33a and the plunger 34. For this reason, if the end position P is adjusted in the second procedure described above, the kick-down position PK that is the pedal effort peak position can also be adjusted, and the variation in the kick-down position PK can be made relatively small. it can.

  That is, in this embodiment, unlike the first embodiment, the output voltage (kickdown output) of the accelerator sensor 4 at the kickdown position PK is determined by the pedal effort without adjusting the output of the accelerator sensor 4 according to the third procedure. It can be set to be between the peak position and the end position PE. In this way, adjustment relating to the pedal stroke and the output of the accelerator sensor 4 is performed.

  Therefore, also in the accelerator pedal module 31 of this embodiment, the output of the accelerator sensor 4 can be adjusted appropriately, and at the same time, the variation in the terminal position PE of the pedal lever 2 can be reduced. In addition, the variation in the kick-down position PK of the pedal lever 2 can be made relatively small. Further, in this embodiment, since the output adjustment of the accelerator sensor 4 can be omitted, the adjustment work of the accelerator pedal module 32 can be further simplified.

  With respect to the accelerator pedal module 32 of this embodiment, the same effects as those of the accelerator pedal module 1 of the first embodiment can be obtained with respect to the effects other than those described above.

  Note that the present invention is not limited to the above-described embodiments, and a part of the configuration can be changed as appropriate without departing from the spirit of the invention.

  For example, the terminal position adjusting means and the output adjusting means of the present invention, the locking means and the urging means provided in the kick down mechanism are not limited to the members embodied in the above embodiment, Any member that exhibits an equivalent function can be appropriately changed.

  In the second embodiment, the locking means of the present invention for locking the plunger 34 so as to be deviable at a fixed position is constituted by the ball 35 and the first spring 36. However, a pin is used instead of the ball 35. May be.
