<P>PROBLEM TO BE SOLVED: To provide a shift lever locking device of a vehicular automatic transmission capable of reducing the number of parts, having a simple and sturdy structure and excellent durability, and obtaining crisp feeling in shifting operation, without generating operation sound when shift locking is released. <P>SOLUTION: When the locking of a shift lever 1C is released, since a link member 7 and an electromagnetic solenoid 12 abut on each other from the beginning, the link member 7 does not strike on the electromagnetic solenoid 12 at the time of lock releasing accompanied with energizing to the electromagnetic solenoid 12, so that striking sound is not generated. Since limited members such as the electromagnetic solenoid 12, a holder 3, a moving element 4, the link member7, and a sliding casing 6 are required, the number of parts can be reduced and a simple and sturdy structure is materialized. The moving element 4 is slid to an uneven surface portion of the sliding casing 6, so that crisp feeling can be obtained in shifting operation to each range. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a shift lever lock device for a vehicular automatic transmission that locks and releases a shift lever by controlling energization of an electromagnetic solenoid.

A shift lever lock device of a vehicle (AT vehicle) equipped with an automatic transmission performs reverse lock, parking lock, and the like in order to secure operation using an electromagnetic solenoid device. In the reverse lock, when the traveling speed exceeds a certain value, the shift to the R range is regulated to prevent the occurrence of an impact due to a sudden reverse movement.
In the parking lock, when the shift lever is positioned in the parking range, the operation of the shift lever is restricted to the parking range by the shift lock. As the foot brake is depressed, the shift lever is unlocked, allowing the shift lever to be shifted. Thereafter, the vehicle is allowed to start, and the vehicle is prevented from starting suddenly by an inadvertent shift operation from the parking range.

  In the shift lever lock device, the release of the shift lock by the operation of the foot brake is performed, for example, by lateral displacement using a gate type or column type operation unit, or by pressing a release button provided on the knob of the shift lever. . In the case of a release button, when the shift lever is positioned in the parking range when the vehicle is stopped, the electromagnetic solenoid device returns to the lock position of the lock mechanism to prevent the release button from being pressed. When the foot brake is stepped on, the energization of the electromagnetic solenoid device displaces the lock mechanism from the lock position to the release position, thereby enabling the release button to be pressed (see, for example, Patent Documents 1, 2, and 3).

  In Patent Document 1, a follower member and a stopper member are provided so as to be swingable. When the shift lever is locked, the metal plate is in a position where it abuts the electromagnet. When the lock is released, the metal plate is rotated while adsorbed to the electromagnet from the contact position. Sound is not generated as an operating sound.

In Patent Document 2, the cam link and the stopper link are rotatably provided. When the shift lever is locked, the shift lever is attached to the stopper link while the cam link is rotated by pressing the pressing pin against the inclined surface of the cam link. Shift displacement is prevented by contacting the stopper surface.
When the shift lever is unlocked, the solenoid and the bracket are rotated together by energizing the solenoid. Thereby, since the cam link and the stopper link rotate in conjunction with each other, the shift lever passes without contacting the stopper surface of the stopper link, and the shift operation to the drive range becomes possible.

In Patent Document 3, when the shift lever is unlocked, the first movable iron core and the second movable iron core rotate while adsorbing from the position where the solenoid coil is energized as the solenoid coil is energized. At this time, since the first movable iron core and the second movable iron core are in contact with each other from the beginning, the first movable iron core and the second movable iron core do not come into contact with each other when the solenoid coil is energized. No sound is generated.

However, in Patent Document 1, a long driven member provided on the rotating shaft, a stopper member, an electromagnet, a metal plate, and the like are required, and the number of parts increases, the structure becomes complicated, and space saving is achieved. There are difficult inconveniences.
Also in Patent Document 2, when the pressing pin is pressed against the inclined surface of the cam link, the cam link is rotated in a plane perpendicular to the pressing direction of the pressing pin. There is a fear. An unstable support structure using a cam link, a stopper link, a solenoid, a solenoid link, a first support shaft, a second support shaft, a torsion spring, and a return spring is required, and the number of parts increases and the structure becomes complicated.

  In Patent Document 3, the solenoid coil is positioned at the center of rotation of the lock plate and the link plate, so that the lock plate and the link plate are compactly accommodated in the casing, and space saving is achieved. On the other hand, a lock plate, a link plate, a first movable iron core, a second movable iron core, and the like are required together with the solenoid coil, and the number of parts increases as in Patent Documents 1 and 2, resulting in a complicated structure.

  The present invention has been made in view of the above circumstances, and its purpose is not to generate an operating noise when the shift lock is released due to energization of the solenoid, and the number of parts can be reduced, and the durability is simple and robust. Another object of the present invention is to provide a shift lever locking device for an automatic transmission for a vehicle that is excellent in cost and advantageous in terms of cost and can provide a sense of moderation in a shift operation.

(About claim 1)
A shift lever provided in the vehicle interior so as to be capable of a shift operation is provided with a mover interlocking with the shift operation. The mover is provided so as to be displaceable in an arbitrary direction with respect to the shift lever, and is urged outward by an elastic member. The sliding casing is disposed in the vicinity of the mover and has a surface portion that undulates by a valley portion and a mountain portion corresponding to the shift range of the automatic transmission. Along with the shift operation of the shift lever, the mover slides the surface portion of the sliding casing so as to cross the valley and the mountain while bending the elastic member.
In the shift range, a link member is provided that can move the inclined surface of the valley corresponding to a predetermined range position relative to the mover. The link member includes a lock position in which the inclined surface is immersed to bring the movable element into contact with the vertical wall portion generated in the valley, and an unlock position in which the inclined surface appears so that the movable element can slide on the inclined surface. Displace between.
The electromagnetic solenoid abuts the link member, attracts and holds the link member at the unlocked position by electromagnetic force generated by energization, and slides the mover on the inclined surface to shift from the predetermined range position to another position. Allows shifting to range. When the electromagnetic solenoid is not energized, the shift operation is stopped by bringing the mover into contact with the vertical wall that appears by separating the link member at the lock position.

Since the electromagnetic solenoid in this configuration is in contact with the link member at the unlock position, when the shift lever is unlocked, the link member is attracted while being in contact with the electromagnetic solenoid as the electromagnetic solenoid is energized.
That is, since the link member and the electromagnetic solenoid are in contact with each other from the beginning, the link member does not hit the electromagnetic solenoid when the lock is released when the electromagnetic solenoid is energized, and no hitting sound is generated.

In addition, since it can be constituted by limited members such as an electromagnetic solenoid, a mover, a link member, and a sliding casing, the number of parts can be reduced and a simple structure can be obtained. Since the mover is slid on the uneven surface of the sliding casing, a moderation with alternating sense of restraint and release is obtained when shifting to each range, and the overall structure is robust. Excellent durability and cost advantage.
The mounting position of the mover only needs to be a location that can transmit the displacement of the shift lever during the shift operation. Therefore, the mounting position of the mover and the sliding casing is highly optional, and a great degree of freedom in design can be obtained. It is done.

(About claim 2)
A biasing member that biases the link member in the direction of the unlock position is attached to the link member. The elastic force of the elastic member is set larger than the urging force of the urging member and smaller than the sum of the urging force of the urging member and the electromagnetic force of the electromagnetic solenoid.
When the electromagnetic solenoid is energized, the inclined surface is held in the unlocked position by the urging force of the urging member and the electromagnetic force of the electromagnetic solenoid, and the mover slides on the inclined surface from the predetermined range position to another shift range. Allow shift operation.
When the electromagnetic solenoid is not energized, the mover depresses the inclined surface against the urging force of the urging member and shifts the outer surface of the mover in contact with the vertical wall as the shift lever is operated. Stop operation.

  In this configuration, locking and releasing of the shift operation are set according to the magnitude relationship between the elastic force and the urging force and the magnitude relationship between the sum of the urging force and the electromagnetic force with respect to the elastic force. For this reason, when realizing the shift lock and release, it is only necessary to adjust the elastic force of the elastic member, the urging force of the urging member, and the power supplied to the electromagnetic solenoid. It can also contribute to weight reduction.

(Claim 3)
Since the elastic member is a compression coil spring, the elastic member has a relatively simple structure and is easily available and easily procured.

(About claim 4)
The mover is a leaf spring which is integrally formed from a back portion having a circular cross section and an arc-shaped abdomen having a flat bottom end and curled upward, and also serves as an elastic member.
Since the mover also serves as an elastic member, it is advantageous in terms of cost by reducing the number of parts. In particular, the back part of the mover is difficult to bend and deform because the cross section is arcuate, and the abdomen is curled at the flat lower end, so that it is easily deformed and is suitable as a mover.

(Claim 5)
The mover is a substantially U-shaped leaf spring integrally formed from a wave-like bending spring portion having an upper end portion and an arcuate body portion having a lower end portion.
Also in this case, since the mover also serves as an elastic member as in the case of claim 4, it is advantageous in terms of cost by reducing the number of parts.

(About claim 6)
The mover is set to be substantially perpendicular to the operation direction of the shift lever, and the uneven surface portion of the sliding casing is set to be substantially parallel to the operation direction of the shift lever.

  In this case, the distance of the mover relative to the surface portion of the sliding casing is substantially constant without changing with respect to the operation direction of the shift lever. For this reason, as the shift lever is shifted from the P range to the L range, when the mover is slid on the sliding casing, the mover always engages the pressing portion firmly with the trough. The operation function of the shift lever can be enhanced.

  The shift lever can be locked and released in a cost-effective manner, eliminating the generation of operating noise associated with energizing the solenoid coil when the shift lock is released when the foot brake is depressed, and reducing the number of parts and simplifying Structure. In addition, since the movable element is slid on the uneven surface portion of the sliding casing, a moderation feeling can be obtained in the shift operation, and the entire structure is robust and excellent in durability.

1 to 3 show a first embodiment of the present invention. As shown in FIG. 1, a shift operation input unit 1 </ b> A in the shift lever locking device 1 of the vehicle automatic transmission is provided in a console (not shown) in the vehicle interior.
The shift lever lock device 1 is, for example, a straight type. A shift lever 1 </ b> C having a grip 1 </ b> B at the tip is attached to the speed change operation input portion 1 </ b> A so as to be rotatable about a support shaft 2 in a substantially vertical plane. The shift lever 1C is shifted to, for example, each position of the P range (parking range), R range, N range, D range, 2nd speed range, and L range. In this case, a part of the large-diameter head-shaped grip 1B is directed toward the traveling direction M of the vehicle as the protruding side 1D, so that the fingers can be easily caught on the protruding side 1D of the grip 1B during the shift operation.

  As shown in FIG. 1, the lower end of the shift lever 1 </ b> C is positioned below the support shaft 2 and includes a tubular holder 3. In the holder 3, a plug-like movable element 4 having a substantially hemispherical pressing portion 4 a formed at the lower end is disposed so as to be slidable in an arbitrary direction. A compression coil spring 5 is provided as an elastic member in the holder 3, and the movable element 4 is slid outwardly by its elastic force.

A sliding casing 6 made of, for example, resin is disposed below the mover 4, and the upper surface portion thereof is a trough corresponding to the shift range (P, R, N, D, 2nd speed, and L) of the automatic transmission. It is undulated in an uneven shape by 6a and peak 6b. The mover 4 slides on the upper surface portion of the sliding casing 6 so as to cross the valley portion 6a and the mountain portion 6b in accordance with the shift operation of the shift lever 1C.
That is, each time the shift range is changed, the movable element 4 in the holder 3 gets over the peak portion 6b while bending the compression coil spring 5, and is restrained by the adjacent valley portion 6a by the elastic force Pf of the compression coil spring 5. .

  Among the shift ranges, as a predetermined range position, for example, in the valley portion 6a corresponding to the parking range (P range), the inclined surface 6c on the R range side appears and disappears with respect to the movable element 4 by a link member 7 made of resin, for example. Displaceable. As shown in FIG. 2, the link member 7 has a substantially U-shape with an opening at the top, and the horizontal rail portion 7a and the operating leg portion 7b and the supporting leg portion 7c provided on both sides of the horizontal rail portion 7a. It consists of.

  That is, in the sliding casing 6, the portion corresponding to the inclined surface of the valley 6a in the parking range is formed with the insertion hole 8 penetrating in the vertical direction. In the sliding casing 6, a vertically long hole 9 is formed substantially parallel to the insertion hole 8 on the opposite side of the valley portion 6 a from the R range. The link member 7 is inserted into the insertion hole 8 so as to be slidable up and down, and the support leg 7c is inserted into the vertically elongated hole 9 so as to be slidable up and down so that the tip end portion of the operating leg 7b functions as the inclined surface 6c. Yes.

The link member 7 has a lock position (see FIG. 2) where the inclined surface 6c is immersed and a vertical wall portion 6f is formed in the peak portion 6b, and an unlock position (see FIG. 3) where the inclined surface 6c appears in the valley portion 6a. It is supposed to be displaced between.
A compression coil spring S is provided as a biasing member between the horizontal rail portion 7a of the link member 7 and the base leg portion 6e of the sliding casing 6, and biases the link member 7 in the direction of the upper unlock position. is doing.

  An electromagnetic solenoid 12 in which a coil 11 is mounted on a bobbin 10 is attached to the back surface ceiling portion 6 d of the sliding casing 6. The electromagnetic solenoid 12 is disposed corresponding to the horizontal rail portion 7 a of the link member 7. An operation plate 13 made of a magnetic material facing the suction surface portion 12a of the electromagnetic solenoid 12 is fixed to the inner surface side of the horizontal rail portion 7a.

  In this case, the elastic force Pf of the compression coil spring 5 in the holder 3 is larger than the urging force Rf of the compression coil spring S and smaller than the sum of the urging force Rf of the compression coil spring S and the electromagnetic force Mf of the electromagnetic solenoid 12. (Rf <Pf <Rf + Mf).

In the above configuration, when the shift lever 1C is in the P range and either the foot brake or the ignition key (not shown), or neither, is operating, the electromagnetic solenoid 12 is in a non-energized state.
When the electromagnetic solenoid 12 is not energized, the link member 7 is urged upward by the urging force Rf of the compression coil spring S to bring the operating plate 13 of the horizontal beam portion 7a into contact with the suction surface portion 12a of the electromagnetic solenoid 12. (See the two-dot chain line in FIG. 2).

  In this state, when the pressing portion 4a of the mover 4 presses the inclined surface 6c against the biasing force Rf of the compression coil spring S and tries to perform the shifting operation of the shift lever 1C, the link member 7 is inserted. It slides downward in the insertion hole 8 and the vertically long hole 9.

  For this reason, the contact of the operation plate 13 with the suction surface portion 12a is released, and the operation plate 13 is separated from the suction surface portion 12a. As a result, the movable element 4 abuts the outer surface 4b against the vertical wall 6f that appears, and stops the shift operation of the shift lever 1C (lock position).

  At the unlocked position where the electromagnetic solenoid 12 is energized, the urging force Pf of the compression coil spring 5 has a mechanical relationship that is smaller than the sum of the urging force Rf and the electromagnetic force Mf. Therefore, the mover 4 slides the pressing portion 4a along the inclined surface 6c while bending the compression coil spring 5, and allows the shift operation from the P range to another shift range to release the lock. {See Figure 3}.

  Since the electromagnetic solenoid 12 in this configuration is in contact with the operation plate 13 of the link member 7 at the unlocked position, the operation plate 13 of the link member 7 is energized with the energization of the electromagnetic solenoid 12 when the shift lever 1C is unlocked. Is attracted by the suction surface portion 12 a while being in contact with the electromagnetic solenoid 12.

  That is, since the link member 7 and the operation plate 13 of the electromagnetic solenoid 12 are in contact with each other from the beginning, the link member 7 does not hit the electromagnetic solenoid 12 when the lock is released when the electromagnetic solenoid 12 is energized. There is nothing to do.

Moreover, since it can be constituted by limited members such as the electromagnetic solenoid 12, the holder 3, the mover 4, the link member 7 and the sliding casing 6, the number of parts can be reduced and the structure can be simplified. Since the movable element 4 is slid on the concavo-convex upper surface portion of the sliding casing 6, a moderation feeling in which a restraining sensation and an opening sensation are alternately provided can be obtained during a shift operation to each range, and the entire structure Is robust and has excellent durability and cost advantage.
The mounting position of the mover 4 may be any place that can transmit the displacement of the shift lever 1C during the shift operation. Therefore, the mounting position of the mover 4 and the sliding casing 6 is highly optional, and the design is large. A degree of freedom is obtained.

  Further, the locking of the shift operation and the release thereof are set by the magnitude relationship between the elastic force Pf and the urging force Rf and the magnitude relationship between the urging force Rf with respect to the elastic force Pf and the sum of the electromagnetic force Mf. For this reason, when realizing the shift lock and release thereof, it is only necessary to adjust the elastic force Pf of the compression coil spring 5, the urging force Rf of the compression coil spring S, and the power supplied to the electromagnetic solenoid 12, respectively, and the structure becomes simple. It is advantageous in terms of cost and can contribute to the overall weight reduction.

FIG. 4 shows a second embodiment of the present invention. The second embodiment differs from the first embodiment in that the holder 3 together with the movable element 4 is substantially parallel to the support shaft 2 and is substantially perpendicular to the shift lever 1C, that is, substantially perpendicular to the operating direction of the shift lever 1C. It is installed like so.
In this case, the holder 3 is positioned between the speed change operation input portion 1A and the support shaft 2, but it may be provided at the lower end portion of the support shaft 2 of the shift lever 1C.

  With the shift operation of the shift lever 1 </ b> C, the mover 4 of the holder 3 draws an arc locus H centering on the support shaft 2. With the change in the mounting position of the holder 3, the sliding casing 6 is formed in a fan shape (sector) concentric with the arc locus H and installed on the arc locus H. In this state, the mover 4 of the holder 3 is oriented in a substantially perpendicular state to the concave and convex upper surface portion of the sliding casing 6.

  In the second embodiment, since the sliding casing 6 is installed on the arc locus H of the mover 4, the distance between the mover 4 and the upper surface of the sliding casing 6 is substantially constant without changing on the arc locus H. become. For this reason, when the movable element 4 is slid on the sliding casing 6 as the shift lever 1C is shifted from the P range to the L range, the movable element 4 always firmly presses the pressing portion 4a to the valley portion 6a. As a result, the operation function of the shift lever 1C can be enhanced. The sliding casing 6 may be a wide flat rectangular shape instead of a fan shape. That is, as long as the shift lever 1C is shifted from the P range to the L range, the sliding casing 6 only needs to have a width dimension that allows the mover 4 to slide without excess or deficiency.

5 and 6 show a third embodiment of the present invention. In the third embodiment, the movable element 14 also serving as the compression coil spring 5 of the first embodiment is formed by a plate spring {see (a) and (b) of FIG. 5}.
The leaf spring movable element 14 is composed of a back part 14a having a circular cross section and an arcuate abdomen part 14b in which the lower end part of the back part 14a is flattened and curled upward. The back portion 14a is made to correspond to the vertical wall portion 6f of the valley portion 6a in the parking range, and the lower end surface portion of the abdominal portion 14b is made to correspond to the inclined surface 6c with the pressing portion.

  Thereby, in the locked position shown in FIG. 5A, the back portion 14a of the mover 14 comes into contact with the vertical wall portion 6f, and the shift operation from the P range to another range is prevented. In the unlock position shown in FIG. 6A, the mover 14 allows the shift operation from the P range to another range by sliding the lower end surface portion along the inclined surface 6c while bending the abdomen 14b. To do.

In Example 3, the back part 14a of the mover 14 is difficult to bend because the cross section is arcuate, and the abdomen 14b is easily bent and deformed because the flat lower end is bent in a curl shape. Is preferred. Since the mover 14 also serves as the compression coil spring 5 of the first embodiment, the number of parts can be reduced, which is advantageous in terms of cost.
In addition, as shown in FIG. 6B as a modification of the third embodiment, a slit 14c may be formed in the abdomen 14b of the mover 14 so that the abdomen 14b is easily elastically deformed. Instead of the slit 14c, a hole or a notch may be provided, and the abdomen 14b may be formed by a fork or a perforated plate having a large number of small holes.

7 and 8 show a fourth embodiment of the present invention. In the fourth embodiment, the movable element 15 also serving as the compression coil spring 5 of the first embodiment is formed by a substantially U-shaped plate spring {see FIGS. 7A and 7B}.
The leaf spring movable element 15 is integrally formed from a wavy flexible spring portion 15a at the upper end and an arcuate body portion 15b at the lower end. The outer surface portion of the body portion 15b is made to correspond to the vertical wall portion 6f of the valley portion 6a, and the lower end surface portion of the body portion 15b is made to correspond to the inclined surface 6c with the pressing portion.

Accordingly, at the lock position shown in FIG. 7A, the outer surface portion of the body portion 15b of the mover 15 comes into contact with the vertical wall portion 6f, thereby preventing a shift operation from the P range to another range. In the unlocked position shown in FIG. 8, the mover 15 slides the outer end surface portion of the body portion 15b along the inclined surface 6c while bending the bending spring portion 15a, and performs a shift operation from the P range to another range. Is acceptable.
Also in the fourth embodiment, since the mover 15 also serves as the compression coil spring 5 of the first embodiment, the number of parts can be reduced as in the third embodiment, which is advantageous in terms of cost.

  FIG. 9 shows a fifth embodiment of the present invention. In the first embodiment, the protruding side 1D of the grip 1B is directed in the traveling direction of the vehicle. In the fifth embodiment, the protruding side 1D of the grip 1B is directed in the direction of the driver seat Ds. In this case, it may be convenient from the viewpoint of the shift operation depending on the improvement of the design of the shift lever 1C and how to put the fingers on the grip 1B.

FIG. 10 shows Embodiment 6 of the present invention. The difference between the sixth embodiment and the first embodiment is that the sliding casing 6 is curved in an arc shape so as to be concave on the movable element 4 side.
The curved shape of the sliding casing 6 matches the arcuate locus K drawn by the pressing portion 4a of the mover 4 in accordance with the shift operation of the shift lever 1C. For this reason, the mover 4 of the holder 3 is oriented in a substantially perpendicular state to the concave and convex upper surface portion of the sliding casing 6. That is, the direction of the mover 4 is substantially parallel to the depth direction of the crest 6b and the protruding direction of the trough 6a in the sliding casing 6.

  In the sixth embodiment, as in the second embodiment, the distance between the sliding casing 6 and the mover 4 is substantially constant without changing on the arc locus K. For this reason, when the movable element 4 is slid on the sliding casing 6 as the shift lever 1C is shifted from the P range to the L range, the movable element 4 always firmly presses the pressing portion 4a to the valley portion 6a. It comes to engage.

(A) In Embodiment 1-4, the compression coil spring S is used as the biasing member. However, biasing means such as a torsion coil spring, slip ring, and leaf spring may be used. The same applies to the compression coil spring 5 as an elastic member in the first embodiment.
(B) The pitch width and height dimension of the concavo-convex shape formed by the valley 6a and the peak 6b of the sliding casing 6 can be variously changed according to the specifications to be mounted.

(C) The mounting position of the mover 4 with respect to the shift lever 1C is not limited to a position that is substantially perpendicular (substantially perpendicular) or substantially parallel to the shift lever 1C, and the displacement of the shift lever 1C during the shift operation is determined by the sliding casing 6. Any part that can be communicated to
(D) Although the link member 7 is formed in a substantially U shape from the horizontal rail portion 7a, the operating leg portion 7b, and the support leg portion 7c, the link member 7 may have a substantially L shape in which the support leg portion 7c is omitted.
(E) Although the object for which the shift operation is locked by the movers 4, 14 and 15 is set to the P range as the predetermined range position, it may be the R range or the N range.

  According to the present invention, the shift lever can be locked and released advantageously in terms of cost, and the number of components can be reduced while eliminating the generation of operating noise associated with energization of the solenoid coil when the shift lock is released. It becomes. In addition, since the movable element is slid on the uneven surface portion of the sliding casing, a moderation feeling can be obtained in the shift operation, and the entire structure is robust and excellent in durability. Demand is aroused by these conveniences and can contribute to the machine manufacturing industry through the distribution of related parts.
