Description

  The present invention relates to a pedal device for an automobile capable of adjusting the position of a pedal.

  Conventionally, various kinds of pedal devices for automobiles have been proposed (for example, Patent Documents 1 and 2). For example, in Patent Document 1, a manual stepped type is adopted as a structure relating to the position adjustment of the pedal, and a support member that holds the rotation center of the pedal position adjustment handle (68) and the pedal (18) ( 34). For this reason, the stroke of the pedal position adjustment handle and the stroke of the pedal position adjustment match. The direction of pedal position adjustment is set to a direction in which the pedal tread surface moves in parallel. Further, the pedal ratio is kept constant by enabling movement of the pedal rotation center and the brake booster connection position when the pedal is depressed.

On the other hand, in Patent Document 2, a manual stepped type is adopted as a structure for adjusting the position of the pedal, and the holding mechanism of the adjustment lever (10) is simplified.
JP-A-8-30346 (Fig. 1-2) Japanese Unexamined Patent Publication No. 2004-90803 (FIG. 1-2)

  By the way, in Patent Document 1, the stroke of the pedal position adjustment handle is the same as the stroke of the pedal position adjustment, and the operation position of the pedal position adjustment handle differs for each position of the pedal. That is, there is no so-called idling mechanism for returning the adjusted operation position of the pedal position adjusting handle to a predetermined position regardless of the position of the pedal. For example, when the pedal position is returned to the initial position, it is necessary to return the operation position of the pedal position adjusting handle to a predetermined position (initial position) corresponding thereto. In addition, there are two patterns for the pedal position adjustment handle, the “push” direction and the “pull” direction in the vehicle front-rear direction according to the pedal position adjustment direction, and the pedal position adjustment handle operation position. Also, the operation of the pedal position adjusting handle becomes complicated because it differs depending on the position of the pedal.

  On the other hand, in Patent Document 2, when adjusting the position of the pedal, the operating force is applied to the cable (24) to release the lock of the adjusting lever by the lock member (20), and the position of the pedal is pressed with a foot. After adjustment, it is necessary to release the operating force again and lock the adjustment lever with the lock member. For this reason, the usability and operability in adjusting the position of the pedal are poor for the user.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an automobile pedal device that can fix the position of an input unit that applies an operating force regardless of the adjustment position of the pedal and can improve operability.

  In order to solve the above-described problems, the invention according to claim 1 is characterized in that an operating force is applied to a base member fixed to a vehicle body and a side that is rotatably connected to the base member and rotates in one direction. And a position adjusting lever to which an urging force is applied to the side rotating in the other direction so as to return to the predetermined rotating position by releasing the operating force, and a pivotally connected and engaged with the position adjusting lever.

When the locking member and the adjustment member at the final rotation position are unlocked, the adjustment is performed as the adjustment member is biased by the biasing member in the other direction. When the member is locked at the first rotation position where the amount of rotation in one side direction is minimized, the engagement piece detached from the engagement groove is reinserted into the engagement groove. The gist is provided with a return member for guiding the piece.

  According to this configuration, when the locking of the adjustment member at the final rotation position is released, with the rotation of the adjustment member biased by the biasing member in the other side direction, The adjusting member is locked at the first-stage rotation position where the amount of rotation in one side direction is minimized. At this time, the engagement piece is guided by the return member so that the engagement piece detached from the engagement groove is inserted into the engagement groove again. Thus, the adjustment member locked at the final stage rotation position is urged by the biasing member when the lock is released, so that the first stage from the final rotation position. It rotates as it is to the rotation position. Further, the engagement piece guided by the return member and reinserted into the engagement groove engages with the engagement groove (engagement wall portion). As described above, the adjustment member is rotated step by step from the first-stage rotation position to the final-stage rotation position by sequentially applying the operation force, and at the final-stage rotation position. The position of the pedal supported by the adjustment member is adjusted in a stepwise manner so that the biasing member is urged by the urging member to directly rotate (return rotation) to the first rotation position. Can do.

It is inserted again into the engaging groove 29 while resisting. Thus, the position adjustment / locking of the adjuster link 17 to the first (first) rotation position is completed.

  When the pedal position adjustment wire is returned in this state, the position adjustment lever 15 and the lock release lever 12 are returned in the same manner as in FIGS. 7 to 8 (see FIG. 3). Thus, the step feed (two-step feed) from the three-stage (final stage) rotation position of the adjuster link 17 to the first-stage (first stage) rotation position is completed.

  As described above, the positions of the brake pedal 19 and the electronic accelerator unit 20 are adjusted together with the adjuster link 17 whose rotational position is adjusted in the above-described manner.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) In the present embodiment, when the position adjustment lever 15 is rotated in one direction by applying an operating force via the lock release lever 12, the position adjustment hook 16 is moved to one step (one step or A vertical length corresponding to the engagement piece 16a so as to rotate integrally until the adjuster link 17 at the second (second) rotation position is locked at the second (second or third) rotation position. The walls 29a and 29d are pressed. As a result, the adjuster link 17 is rotated from the rotation position of one stage (one or two stages) to the rotation position of the next stage (two or three stages) and supported by the adjuster link 17. The positions of the brake pedal 19 and the electronic accelerator unit 20 are adjusted. When the position adjusting lever 15 returns to the predetermined rotation position by releasing the operating force and applying an urging force to the position adjusting lever 15, the position adjusting hook 16 is moved from the corresponding vertical wall portions 29a and 29d. The engagement piece 16a is returned to a predetermined position corresponding to the predetermined rotation position while being separated. That is, the position adjusting lever 15 and the position adjusting hook 16 are always set to the predetermined rotation position and the predetermined position corresponding to the predetermined rotation position, respectively, before and after the adjustment of the brake pedal 19 and the electronic accelerator unit 20. Returned and arranged (so-called idle swing mechanism). Therefore, the position of the pedal position adjustment wire that applies the operating force to the position adjustment lever 15 via the lock release lever 12 can be fixed regardless of the adjustment positions of the brake pedal 19 and the electronic accelerator unit 20. . Further, since the operation force is applied through the lock release lever 12 only in one side direction in which the position adjusting lever 15 is rotated in one side direction, the confusingness of the operation can be eliminated.

  (2) In the present embodiment, the adjuster link 17 is rotated stepwise over a plurality of (1 to 3) rotation positions by sequentially applying the operating force via the lock release lever 12. The positions of the brake pedal 19 and the electronic accelerator unit 20 supported by the adjuster link 17 can be adjusted stepwise.

  (3) In the present embodiment, when the adjuster link 17 is unlocked at the three-stage (final stage) rotation position, the adjuster link 17 biased by the spring 36 is moved in the other direction. Along with the rotation, the adjuster link 17 is locked at the first (first) rotation position where the amount of rotation in one side direction is minimized. At this time, the engagement piece 16 a is guided by the return bracket 30 so that the engagement piece 16 a detached from the engagement groove 29 is inserted into the engagement groove 29 again. In this way, the adjuster link 17 locked in the three-stage (final stage) rotational position is urged by the spring 36 by releasing the latch, and the three-stage (final stage) is rotated. It rotates as it is from the rotation position to the rotation position of the first stage (first stage). Further, the engaging piece 16a guided by the return bracket 30 and reinserted into the engaging groove 29 is engaged with the engaging groove 29 (vertical wall portion 29a). As described above, the adjuster link 17 is rotated step by step from the first-stage (first stage) rotation position to the third-stage (last stage) rotation position by sequentially applying the operating force. At the stage (final stage) rotational position, the brake 36 is urged by the spring 36 to rotate to the first stage (initial stage) rotational position as it is (returned), so that the brake supported by the adjuster link 17 is supported. The positions of the pedal 19 and the electronic accelerator unit 20 can be adjusted stepwise and in a round.

  (4) In the present embodiment, the position adjusting hook 16 has the slit 21a of the pedal bracket 11 (guide bracket 21) when the adjuster link 17 is locked at the three-stage (final) rotation position. By having the position adjustment locking portion 16 b that is locked to the position adjustment hook 16, the position adjustment lever 15 to which the position adjustment hook 16 is connected is locked to the pedal bracket 11 via the position adjustment hook 16. For this reason, swinging of the position adjusting lever 15 can be suppressed.

In addition, you may change the said embodiment as follows.
In the embodiment, the plurality of lock holes 17a of the adjuster link 17 may be connected to each other in a long hole shape as long as the locking claws 14a of the lock bracket 14 can be selectively fitted.

In the above-described embodiment, the adjuster link 17 may be sent one by one in order from the rotation position of the third stage (final stage) to the rotation position of the first stage (first stage).
In the above-described embodiment, the number of rotation positions where the adjuster link 17 is locked may be two or four or more.

  In the above-described embodiment, the positions of the brake pedal 19 and the electronic accelerator unit 20 are adjusted with the adjuster link 17 and the like to form a four-bar rotation chain. However, the brake pedal 19 and the electronic accelerator unit 20 are connected to the adjuster link 17. You may go directly to.
