Description

  The present invention relates to a shift operating device for operating a transmission of a vehicle and a movement restricting device for restricting movement of a moving body that moves on a fixed track such as a shift lever in such a shift operating device.

  A so-called “shift lever device” is generally used as an operation device for a vehicle occupant to operate an automatic transmission of a vehicle. This type of shift lever device includes a shift lever having a distal end extending toward the vehicle interior side.

  The shift lever can be rotated around an axis whose axial direction is one or two directions on the base end side. The rotation position of the shift lever is detected by the automatic transmission via a connection means such as a wire or cable, or a position detection means such as a micro switch, and when the shift lever reaches a predetermined shift position, the automatic transmission Of the plurality of preset shift ranges, the shift range is changed to the shift range corresponding to the reached shift position.

  Further, this type of shift lever device is provided with a shift lock mechanism (refer to Patent Document 1 below for an example of a shift lever device provided with the shift lock mechanism).

  In the shift lock mechanism, a lock member is provided in the vicinity of a shift position corresponding to a parking range that locks a driving wheel of a vehicle among the plurality of shift ranges (hereinafter, this shift position is referred to as “P position” for convenience). ing. The lock member is provided on the movement locus of the shift lever that moves from the P position to another shift position. When the shift lever tries to move from the P position to another shift position, the shift lever interferes with the lock member, It cannot move to another shift position.

However, the lock member is connected to the plunger of the solenoid. For example, when the brake pedal of the vehicle is depressed, the solenoid is energized. Evacuates. In this retracted state, the shift lever can be moved without being interfered with the lock member, and thus the shift lever can be moved from the P position to another shift position.
Japanese Laid-Open Patent Publication No. 7-286658

  By the way, when the solenoid is energized and the plunger moves, the plunger collides with the iron core provided inside the solenoid. Therefore, every time the shift lever is restricted by the lock member, that is, the shift lock is released, a collision sound between the iron core and the plunger is generated. For this reason, there is still much room for improvement from the viewpoint of quietness.

  An object of the present invention is to obtain a shift operation device and a movement restricting device with high silence performance in consideration of the above facts.

  The shift operation device according to the first aspect of the present invention includes a plurality of shifts set in a transmission of a vehicle by moving on a predetermined track and reaching a specific shift position on the track. The operating means that can be changed to a shift range corresponding to the reached shift position in the range, and provided corresponding to the predetermined position on the orbit, approaching the predetermined position in the state of the predetermined position, or The control means that interferes with the operation means that has reached the predetermined position and restricts the movement of the operation means, and the restriction means that can be detached from the predetermined position, and the biasing means that biases the restriction means toward the predetermined position And the permanent magnet provided in the operating means or the restricting means, and the restricting means and the operating means, which are provided on the side where the permanent magnet is not provided, and are energized to energize the permanent magnet. Rebounded, and, a, an electromagnet which emits magnetic force direction and magnitude against the biasing force of the biasing means.

  In the shift operation device according to claim 1, when the operation means moves on a predetermined track, and reaches a predetermined specific position on the track, the transmission is preset in the vehicle transmission. Among the plurality of shift ranges, the shift range is changed to a shift range corresponding to the specific shift position.

  On the other hand, in the shift operation device according to the present invention, the regulating means is urged to a predetermined position on the track by the urging force of the urging means. As a result, basically, when the operating means moves on the track and reaches a predetermined position or immediately before reaching the predetermined position, the operating means is directly or indirectly interfered with the regulating means, The movement of the operating means beyond the position is restricted.

  This prevents the operating means from inadvertently reaching a specific shift position ahead of the predetermined position on the trajectory, and prevents inadvertent switching to the shift range corresponding to the specific shift position.

  On the other hand, in this shift operating device, when the electromagnet provided in the operating means or the restricting means is energized, the magnetic force repels the permanent magnet provided in the operation means and the restricting means where the electromagnet is not provided. Will occur. The repulsive force generated between the permanent magnet and the electromagnet has a direction and a magnitude that resists the urging force of the urging means that urges the restricting means.

  For this reason, when the operating means approaches a predetermined position on the track, the repulsive force causes the regulating means to retreat from the predetermined position on the track against the biasing force of the biasing means. In this state, the operating means can move beyond a predetermined position on the track without being interfered by the regulating means.

  Here, in the shift operation device according to the present invention, the magnetic force generated by energizing the electromagnet as described above is repelled by the magnetic force of the permanent magnet, so that the regulating means is retracted from the predetermined position. Therefore, when the restricting means is retracted from the predetermined position, the operating means does not contact the restricting means.

  Thus, in this shift operating device, there is no collision sound caused by the collision between the operating means and the restricting means in the state where the movement restriction of the operating means is released, and quietness when operating the operating means is achieved. Performance can be improved. In addition, since the operation means and the restriction means do not collide with each other when the movement restriction of the operation means is released, the occurrence of damage to the operation means and the restriction means can be effectively reduced or prevented.

  The movement restricting device according to the present invention described in claim 2 is a movement restricting device that restricts movement of a moving body on a predetermined track at a predetermined position on the track, and corresponds to the predetermined position. In the state of being in the predetermined position, the moving body approaches the predetermined position or interferes with the moving body that has reached the predetermined position to restrict the movement of the moving body and can be detached from the predetermined position. Restricting means, urging means for urging the restricting means toward the predetermined position, a permanent magnet provided on the moving body or the restricting means, and the permanent magnet among the restricting means and the moving body An electromagnet that repels the magnetic force of the permanent magnet when energized and emits a magnetic force in a direction and magnitude against the urging force of the urging means. It is characterized by

  In the movement restricting device according to the second aspect, the restricting means is urged to a predetermined position on the track by the urging force of the urging means. As a result, basically, when the moving body moves on the trajectory and reaches a predetermined position or just before reaching the predetermined position, the moving body is directly or indirectly interfered with the regulating means, and the predetermined position is reached. The movement of the moving body beyond the position is restricted.

  This prevents the moving body from inadvertently reaching beyond a predetermined position on the track.

  On the other hand, in this movement restricting device, when the electromagnet provided on the moving body or the restricting means is energized, the magnetic force repels the permanent magnet provided on the moving body and the restricting means where the electromagnet is not provided. Will occur. The repulsive force generated between the permanent magnet and the electromagnet has a direction and a magnitude that resists the urging force of the urging means that urges the restricting means.

  For this reason, when the moving body approaches a predetermined position on the track, the repulsive force causes the regulating means to retreat from the predetermined position on the track against the urging force of the urging means. In this state, the moving body can move beyond a predetermined position on the track without being interfered by the restricting means.

  Here, in the movement restricting device according to the present invention, the restricting means is retracted from the predetermined position by repelling the magnetic force generated by energizing the electromagnet as described above against the magnetic force of the permanent magnet. Therefore, the moving body does not contact the restricting means when the restricting means is retracted from the predetermined position.

  As a result, in this movement restriction device, there is no collision noise caused by the collision between the moving body and the restricting means in the state where the movement restriction of the moving body is released, and the quietness when the moving body moves Performance can be improved. Further, since the moving body and the restricting means do not collide with each other when the movement restriction of the moving body is released, it is possible to effectively reduce or prevent the damage of the moving body and the restricting means.

  As described above, according to the present invention, no collision noise or the like is generated when the movement restriction of the moving body or the operation means is released, and the quiet performance is high.

<Configuration of the present embodiment>
FIG. 1 shows a shift lever device 10 as a shift operation device according to an embodiment of the present invention (a shift lever device 10 to which a shift lock mechanism 70 as a movement restricting device according to an embodiment of the present invention is applied). The configuration is shown by an exploded perspective view.

  As shown in this figure, the shift lever device 10 includes a lower housing 12. The lower housing 12 is installed, for example, between the driver's seat and the passenger seat of the vehicle or on the back side of the instrument panel.

  The lower housing 12 includes a main body 16 including a pair of side walls 14 facing each other. A mounting piece 20 having a through hole 18 is formed from a pair of side walls 14 constituting the main body 16, and fastening means such as a bolt passing through the through hole 18 is fastened and fixed to a predetermined part of the vehicle. Shift lever device 10 is attached to the vehicle.

  An upper housing 22 is provided on the upper side of the lower housing 12, and the upper housing 22 covers and covers the lower housing 12 from the upper side. Support holes 24 are formed in the pair of side walls 14 constituting the lower housing 12. These support holes 24 are formed coaxially with each other, one end of the shaft 26 is rotatably supported by one support hole 24, and the other end of the shaft 26 is rotatably supported by the other support hole 24. Has been.

  A lever body 30 constituting a shift lever 28 as a moving body or operating means is provided at an axially intermediate portion of the shaft 26. The lever main body 30 is formed in a substantially block shape, and a pair of leg portions 32 and 34 extend from the lower end thereof.

  The shaft 26 passes between the leg portions 32 and 34, and the lever main body 30 is formed by the leg portion 32, the shaft 26, and the shaft 36 penetrating the leg portion 34 in the opposing direction of the leg portions 32 and 34. Is supported on the shaft 36 so as to be rotatable around the shaft 36.

  Further, the lever main body 30 connected to the shaft 26 through the shaft 36 in this way can rotate around the shaft 26 together with the shaft 26. That is, the shift lever 28 including the lever main body 30 can rotate both around the shaft 26 and around the shaft 36 that intersects the axial direction of the shaft 26.

  The shaft 26 is provided with a control lever 38. The control lever 38 includes a flat connecting portion 40, and leg pieces 44 and 46 extend from both ends of the flat plate portion 42 along the axial direction of the shaft 26. The leg pieces 44 and 46 are formed with through holes 48 that are coaxial with each other. The shaft 26 passes through these through holes 48, and the lever body 30 is located between the leg pieces 44 and 46. ing.

  Further, a rectangular hole 50 penetrating along the opposing direction of the pair of side walls 14 is formed in one leg piece 44. Corresponding to this rectangular hole 50, a square bar-like pin 52 is formed protruding from the lever body 30, and the pin 52 passes through the rectangular hole 50. Therefore, the control lever 38 is originally rotatable around the shaft 26 with respect to the shaft 26, but the pin 52 presses the leg piece 44 when the lever body 30 rotates around the shaft 26 together with the shaft 26. Then, the control lever 38 is rotated around the shaft 26.

  A locking piece 54 extends from the leg piece 44, and a locking pin 56 is formed on the distal end side of the locking piece 54. A base end of a flexible long string-like connecting member such as a wire or a cable (not shown) is locked to the locking pin 56. The leading end of the connecting member is directly or indirectly connected to an automatic transmission (not shown), and the control lever 38 rotates around the shaft 26 together with the lever body 30 to automatically displace the connecting member in the longitudinal direction. The transmission is operated.

  Further, the lower housing 12 is provided with detection means such as a micro switch and a magnetic detection switch (not shown), and detects the rotational position of the lever body 30 around the shaft 36. The detection means is electrically connected to the automatic transmission, and the movement amount of the connecting member and the detection result of the lever main body 30 by the detection means among the plurality of shift ranges set in the automatic transmission. A predetermined shift range based on the above is selected and changed.

  On the other hand, a bottomed mounting hole 58 is formed at the tip of the lever main body 30, and a rod-shaped lever portion 60 is fitted therein. The lever portion 60 passes through a zigzag guide hole 62 formed in the upper housing 22 and protrudes to the outside of the upper housing 22, and an occupant holding a knob attached to the tip of the lever portion 60 shifts along the guide hole 62. The lever 28 can be turned.

  Further, the lever main body 30 is provided with a moderation pin accommodating portion 64. The moderation pin accommodating portion 64 is formed in a block shape. The moderation pin accommodating portion 64 is formed with a bottomed accommodating hole 66 opened at the upper end.

  A part of the moderation pin 68 is accommodated inside the accommodation hole 66. A compression coil spring 67 (not shown) is accommodated between the moderation pin 68 and the bottom of the accommodation hole 66, and the moderation pin 68 is urged in a direction protruding from the accommodation hole 66.

  A moderation hole (not shown) is formed on the back surface of the upper housing 22 corresponding to the moderation pin 68. The moderation hole is formed in a bottomed shape that is opened on the back surface of the upper housing 22, and is inserted in a state where the tip is pressed against the bottom of the moderation hole by the urging force of the compression coil spring 67.

  The opening shape of the moderation hole is similar to that of the guide hole 62 described above. When the moderation pin 68 is guided to the moderation hole, the lever portion 60 moves along the guide hole 62 and the lever main body 30 is moved. It rotates around the shaft 26 and the shaft 36.

  On the other hand, as shown in FIG. 1 and more specifically in FIG. 2, a shift lock mechanism 70 is provided on one of the pair of side walls 14. The shift lock mechanism 70 includes a lock lever 72 as a restricting member that constitutes a restricting means.

  In the vicinity of the base end portion in the longitudinal direction of the lock lever 72, a cylindrical cylindrical portion 74 is formed with the opposing direction of the pair of side walls 14 as the axial direction. A shaft portion 78 of a bolt 76 passes through the cylindrical portion 74 and the lock lever 72 in the longitudinal direction, and is rotatably supported around the shaft portion 78.

  The bolt 76 passes through one side wall 14 and is fixed by a nut 80. Around the cylindrical portion 74, a torsion coil spring 82 is provided as a biasing means. One end of the torsion coil spring 82 is locked to a locking pin 56 formed on the side wall 14, and the other end is locked to a lock lever 72.

  A restricting block 84 is formed at the tip of the lock lever 72. Corresponding to the restriction block 84, a contact piece 86 extends from the lever body 30 toward the side wall 14 provided with the shift lock mechanism 70.

  The contact piece 86 in a state in which the lever portion 60 has passed through the position indicated by P in FIG. 7 in the guide hole 62 is the rotation direction around the shaft 36 when the lever portion 60 is detached from the position indicated by P. The torsion coil spring 82 faces the restriction block 84 of the lock lever 72 in a natural state where no external force is applied.

  Therefore, when the lever portion 60 tries to be separated from the position indicated by P, the contact piece 86 contacts the restriction block 84. For this reason, the lever portion 60 cannot reach the position indicated by A in FIG. 7, that is, the position where the lever main body 30 switches from turning around the shaft 36 to turning around the shaft 26.

  Further, as shown in FIG. 2, a permanent magnet 88 is attached to the lever main body 30. The permanent magnet 88 has a direction in which its magnetic pole direction (the direction of the permanent magnet 88 from the north pole to the south pole and the opposite direction) is inclined by a predetermined angle in the axial direction of the shaft 36 with respect to one axial direction of the shaft 26. ing.

  More specifically, the north pole or south pole of the permanent magnet 88 is inclined at a predetermined angle of less than 90 degrees forward in the front-rear direction with respect to the left in the left-right direction in a plan view of the upper housing 22. On the other hand, an electromagnet 90 is provided closer to the center of rotation of the lock lever 72 than the restriction block 84.

  The electromagnet 90 is set so that the magnetic pole is directed opposite to the permanent magnet 88 by energizing a coil (not shown). resist. Moreover, the repulsive force due to the repulsion of the magnetic force is set to a magnitude that resists the spring force of the torsion coil spring 82.

<Operation and effect of the present embodiment>
Next, the operation and effect of the present embodiment will be described.

  In the shift lever device 10, when the lever portion 60 passes the position indicated by P in FIG. 7, the automatic transmission installed in the vehicle is a so-called “parking range” that locks the drive wheels of the vehicle. . When the lever portion 60 is rotated around the shaft 36 along the guide hole 62 in this state, the detection means detects a change in the rotation position of the lever main body 30.

  Further, when the lever portion 60 is rotated around the shaft 26, the connecting member locked to the locking pin 56 of the control lever 38 moves according to the rotation amount of the lever portion 60.

  In this manner, the lever portion 60 is rotated around the shaft 26 and the shaft 36 so that the lever portion 60 reaches the position indicated by R in FIG. 7, and the lever main body 30 has reached this rotation position. When the automatic transmission detects the detection result of the detection means and the amount of movement of the connecting member, the automatic transmission is changed from the “parking range” to a so-called “reverse range” in which the driving wheels are reversed.

  In this way, by further rotating the lever portion 60 around the shaft 36 and the shaft 26 along the guide hole 62, the lever portion 60 is positioned at a position indicated by N, a position indicated by D in FIG. The vehicle automatic transmission is changed to a shift range corresponding to these positions.

  By the way, when trying to move the lever portion 60 from the position indicated by P in FIG. 7 to the position indicated by R, the contact piece 86 of the lever main body 30 contacts the restriction block 84 of the lock lever 72. Thus, in a state where the contact piece 86 is in contact with the restriction block 84, the lever body 30 cannot be further rotated toward the side wall 14 where the lock lever 72 is provided.

  Therefore, as shown in FIGS. 3 and 5, the lever portion 60 is switched from the rotation around the shaft 36 to the rotation around the shaft 26 when being released from the position indicated by P. The lever portion 60 cannot reach the position indicated by R. As a result, the automatic transmission does not switch from the parking range to another shift range, and inadvertent starting of the vehicle is prevented.

  On the other hand, for example, when the vehicle occupant depresses the brake pedal with the lever portion 60 passing the position indicated by P in FIG. 7, the electromagnet 90 is energized and a magnetic field is formed around the electromagnet 90. The

  In this state, when the lever portion 60 is rotated toward the position indicated by A in FIG. 7, the permanent magnet 88 approaches the electromagnet 90. Since the direction of the electromagnet 90 is set so that the magnetic force of the electromagnet 90 is repelled from the magnetic force of the permanent magnet 88, the electromagnet 90 is rotated by the torsion coil spring 82 when the permanent magnet 88 approaches the electromagnet 90. The lock lever 72 is rotated against the spring force.

  As shown in FIGS. 4 and 6, when the lock lever 72 is rotated, the abutting state between the contact piece 86 and the restriction block 84 is eliminated, and the contact piece 86 is not moved even when the lever portion 60 is rotated. There is no contact with the restriction block 84.

  Accordingly, in this state, the lever portion 60 can reach the position indicated by A in FIG. 7, and by further rotating the lever portion 60 around the shaft 26 and the shaft 36 from this state, FIG. The lever portion 60 can be moved to a position indicated by R, N, D or the like.

  Here, as described above, the shift lever device 10 rotates the lock lever 72 by utilizing the repulsion between the magnetic force generated when the electromagnet 90 is energized and the magnetic force of the permanent magnet 88. That is, even when the electromagnet 90 is energized, the magnetic substance is not attracted by the magnetic force.

  Therefore, the shift lever device 10 does not generate a collision sound that is generated when the magnetic material is attracted to the electromagnet 90 and the magnetic material collides with the electromagnet 90 or other members. Therefore, in the present shift lever device 10, the shift lock state that restricts the movement of the lever portion 60 from the position indicated by P in FIG. 7 to the position indicated by R, and the shift lock release that releases the shift lock state The quiet performance when switching from any one of the states to any other can be effectively improved.

  In the state where the shift lock is released, the lock lever 72 is rotated by the repulsion between the magnetic force generated when the electromagnet 90 is energized and the magnetic force of the permanent magnet 88 as described above. Does not contact the restriction block 84.

  Therefore, in the unlocked state of the shift lock, even if the lever portion 60 is moved from the position indicated by P in FIG. 7 to the position indicated by R, the contact piece 86 does not collide with the restriction block 84, meaning this. However, it can prevent collision noise and improve quiet performance.
