Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a shift lever device for shifting a transmission of a vehicle.

[0002]

2. Description of the Related Art A shift lever device for shifting an automatic transmission of a vehicle generally has a structure in which the shift lever is shifted in the front-rear direction of the vehicle to shift the automatic transmission. This type of shift lever device has a configuration in which the operation direction of the shift lever is set in the vehicle front-rear direction. For example, when the shift lever is selected in the P shift range, the shift lever is simply moved in the vehicle rear direction. Thus, a shift operation to the R shift range is possible.

[0003] In such a shift lever device, a shift lock mechanism that enables the shift operation of the shift lever only under specific conditions is required, and the shift from the P shift range to the R shift range as described above is required. Operation must be restricted in some way.

In this case, for example, by providing an electric actuator such as a solenoid near the shift lever, when the shift lever is operated from the P shift range to the R shift range, unless the brake is operated, the actuator is operated by the shift lever. A shift lever device has been proposed in which the shift lever device is configured to be engaged with the shift lever to prevent a shift operation to the R shift range.

In this type of shift lever device (shift lock mechanism), when the shift lever is in the P shift range, the lock plate fixed by the electric actuator engages with the grooved pin to move (lock the knob button). Operation) is prevented, and the shift operation of the shift lever to another shift range other than the P shift range is prevented.

By the way, in the conventional method, even when the solenoid is not energized due to an electrical failure such as a battery rising,
When the key was turned on, the shift was possible, but there was no method for forcibly releasing the shift lock when the lock plate stopped rotating due to some trouble.

However, in such a forced movement structure of the lock plate, since an electric actuator or the like is arranged near or around the grooved pin, there is ample space for disposing other members for manually operating the lock plate. In other words, the space for arranging other members and the moving space for releasing the lock plate are necessarily limited, making it difficult to effectively use the space, and there is room for improvement in this respect.

[0008]

In view of the above facts, the present invention can forcibly release the shift lock by manual operation even in the case of the shift lock state and the like, and manually release the shift lock state and the like. It is an object of the present invention to obtain a shift lever device that is less likely to be restricted by the arrangement space of other members for performing the operation and that can effectively utilize the space.

[0009]

According to a first aspect of the present invention, there is provided a shift lever device for a shift operation of a transmission of a vehicle, the shift lever being provided on the shift lever, and mounted to be moved by operating a knob button. An interlocking member, a detent member provided with a detent groove in which the interlocking member moves adjacently at the time of a shift operation of the shift lever, and a detent member provided when the shift lever is shifted from a parking range position to another range side. A restricting member that is movable from a position at which the shift operation is restricted to a position at which the restriction is released by contacting the interlocking member; and a manually operated moving of the restricting member from the restricting position to a position at which the restriction is released. And an operating member that performs the operation.

With the above-described structure, the operating member is operated to move the limiting member formed on the detent plate portion to a position where it can be moved to another range, and the interlocking member at the parking range position is moved. The user can move from the parking range position to another range side and perform an operation of moving the shift lever from the parking shift position to another shift range. Therefore, the shift operation of the shift lever can be performed even when the shift lock of the shift lever device is locked and the movement of the interlocking member is restricted from the parking range position. Further, when the restricting member formed in the detent plate portion is at a position for restricting the interlocking member from moving to another range side from the parking range position, the interlocking member at the parking range position is operated unless the operation member is operated. A shift lock state of the shift lever device can be provided such that the shift lever device cannot be moved from the parking range position to another range side and the shift lever cannot be moved from the parking shift position to another shift range. Furthermore, the restricting member is formed in the detent plate portion, so that a space for disposing the restricting member and a moving space for releasing the restricting member can be effectively used.

In the first aspect, when the limiting member is mentioned, a part of the detent member is configured to be movable.
And a configuration in which the entire detent member is a movable limiting member.

According to a second aspect of the present invention, in the shift lever device according to the first aspect, the detent groove has a recess for restricting operation of the interlocking member at the parking range position, and the interlocking member is adjacent to the recess. The restricting member has a side portion for the R range for abutment, and the restricting member forms a part of one side portion of the concave portion for the P range and protrudes inward of the detent groove from the side portion for the R range. The portion is configured to be movable.

With the above-described structure, the restricting member formed in the detent plate portion can be formed of a small member, and the moving space for the releasing movement can be set to be narrow, so that the space in the shift lever device can be effectively used. Can be achieved.

As shown in FIG. 3, the detent plate 2
2, the P range concave portion 26 and the R range side portion 28
A restricting member 34 in the shape of a long plate protruding from the side portion 28 for the R range forms one side wall of the concave portion 26 for the P range, and the distal end portion 34A of the restricting member 34 From the position for the R range to the position for releasing the operation restriction indicated by the two-dot chain line from the R range side portion 28 into the detent groove 24. For this reason, the limiting member 34 is mounted on the detent plate 22 so as to be slidable in the longitudinal direction of the long plate.

A shift lock release mechanism is mounted for operating the restricting member 34. In the present embodiment, an operating member 36 having an L-shape is used as the shift lock release mechanism. The operation member 36 has its intermediate portion pivotally attached to the detent plate 22 by a pivot pin 38. An elongated hole 40 is formed at one end of the operation member 36 along the length direction thereof. A round shaft-shaped interlocking pin 42 erected on the side surface near the upper end 34 </ b> B of the restriction member 34 is slidably inserted into the elongated hole 40.

The other end of the operating member 36 is a push button 4
It is formed so as to be able to be pushed in the direction of arrow A from the outer surface of the shift lever device. Then, as shown in FIG. 3, the operation member 36 is operated by pushing its push button 44 in the direction of arrow A.
Arrow B from the position indicated by the solid line to the position indicated by the two-dot chain line in the figure
Rotate in the direction. Then, as the long hole 40 of the operating member 36 rotates in the direction of arrow B, the limiting member 34 interlocked by the interlocking pin 42 sliding in the long hole 40.
Moves from the position shown by the solid line in FIG. 3 to the position shown by the two-dot chain line, so that the distal end portion 34 </ b> A is pulled out from the detent groove 24. When the pressing operation force of the push button 44 is released, the restricting member 34 and the operating member 36 return to the positions indicated by the solid lines in FIG. Further, a stopper S1 and a stopper S2 for regulating the range of the rotation operation of the operation member 36 are provided.

As shown in FIGS. 1 and 2, the shift lever device 10 is provided with a shift lock plate 46 and an actuator 48 for a shift lock mechanism, and a cam plate 50 for a key interlock mechanism. I have.
The shift lock plate 46 has a substantially small rectangular plate shape, and has a base end pivotally mounted on a bracket of the shift lever device 10 by a shaft pin 52, and is disposed adjacent to the detent plate 22. This shift lock plate 46
As shown in FIG. 3, an arc-shaped edge 46 at the tip of the
When A is positioned so as to approach the distal end portion 34A of the restricting member 34, the outlet opening of the P range concave portion 26 is closed, and the end side portion 46A and the distal end portion 34A at the position shown by the solid line in FIG. It is configured such that the grooved pin 20 cannot pass between them.

Further, by rotating the shift lock plate 46 in the direction of arrow D in FIG. 1 to the state shown in FIG. 2,
The edge portion 46A is disengaged from the outlet opening of the P-range recess 26, and the grooved pin 2 in the P-range recess 26 is removed.
0 can be moved from the outlet opening over the distal end portion 34A of the restricting member 34 at the position shown by the solid line in FIGS. 2 and 3, and can be moved to the other range side portions 28, 30, 32 side of the detent groove 24. It is configured to be.

The actuator 48 of the shift lock mechanism for operating the shift lock plate 46 shown in FIGS. 1 and 2 extends the rod 54 from the main body by the urging force of a compression spring (not shown) when the solenoid is not energized. When the solenoid is excited, the rod 54 is pulled into the main body as shown in FIG. 1 against the urging force of a compression spring (not shown). The tip of the rod 54 is connected to the middle of the shift lock plate 46. The actuator 48 is de-energized when the brake pedal is depressed.

Cam plate 50 for key interlock
Is arranged at a position adjacent to the direction (the right side as viewed in FIGS. 1 and 2) of the shift lock plate 46 in which the shift lock plate 46 is rotated out of the outlet opening of the P range concave portion 26. The cam plate 50 has a substantially crescent shape, and a portion near one end (a portion near the upper side in the figure) is axially mounted on a bracket of the shift lever device 10 by a shaft pin 56. Further, a torsion coil spring (not shown) is attached to the shaft pin 56, and the cam plate 50 is urged to rotate in the direction of arrow E in FIG.

At the end of the cam plate 50 on the shaft pin 56 side, a small projecting piece-shaped connecting portion 58 is integrally formed.

As shown in FIG. 1 and FIG.
FIGS. 1 and 2 show a state in which when the grooved pin 20 is present in the P-range concave portion 26 of the detent groove 24, the connecting portion 58 is in contact with the grooved pin 20 so as to follow the withdrawal operation of the grooved pin 20 from the concave portion 26. Move to the state. Since the biasing force of the spring for biasing the grooved pin 20 mounted in the shift lever 12 to move to the tip end side of the shift lever 12 is sufficiently strong, when the knob button of the shift lever (not shown) is released from the state of FIG. The biasing force of this spring overcomes the biasing force of the spring mounted on the shaft pin 56 of the cam plate 50, and rotates the cam plate 50 from the state shown in FIG. 2 to the state shown in FIG.

An engaging hole 62 is provided at an end of the cam plate 50 opposite to the connecting portion 58, and one end of the key lock cable 60 is engaged with the engaging hole 62. The other end of the key lock cable 60 is connected to a key interlock mechanism (not shown).

A protrusion 50A is formed at a predetermined portion of the cam plate 50 near the shaft pin 62 so as to protrude in a column shape from a side plane at a side portion facing the shift lock plate 46. The side of the shift lock plate 46 facing the cam plate 50 has an end 4
A guide surface 64 that is smoothly curved in a substantially S-shape is formed from near 6A to the middle portion, and when the cam plate 50 slightly rotates in the direction of the arrow E, the protrusion 50A slides on the guide surface 64. The operation of the shift lock plate 46 follows the operation of the cam plate 50.

Next, the shift lock mechanism mounted on the shift lever device and the key interlock mechanism will be described with reference to FIGS. 1 and 2. FIG. In this key interlock mechanism, a key is not inserted into a key cylinder (not shown), or even if a key is inserted, LOCK or OF is not inserted.
In the position F, when the key lock cable 60 is not rotated to the position such as ACC or engine ON, the key lock cable 60 is prevented from moving in the direction of arrow K, and the cam plate 50 is rotated in the direction of arrow E. And the state shown in FIG. 1 is maintained.

That is, in the state shown in FIG. 1, the solenoid of the actuator 48 in the shift lock mechanism is not energized, and the shift lock plate 46 is urged to rotate in the direction of arrow D by a compression spring (not shown). However, the guide surface 64 of the shift lock plate 46
Is stopped by hitting the projection 50A of the cam plate 50, so that the state shown in FIG. 1 is maintained.
Therefore, even if a knob button (not shown) of the shift lever 12 is pressed, the grooved pin 20 is restrained by the end side portion 46A of the shift lock plate 46 at the exit of the P range concave portion 26, and cannot be detached from the P range concave portion 26. Therefore, the shift lever 12 is held at the P range position.

Further, the key is inserted into the key cylinder,
ACC, engine ON from LOCK or OFF position
Etc., the key lock cable 60
Becomes movable in the direction of arrow K.

Further, turning the key to turn on the engine,
When the shift lever 12 is in the P range position and the brake is not depressed, the solenoid of the actuator 48 is energized to set the shift lock plate 46 to the position to close the outlet of the P range concave portion 26 shown in FIG. , Cannot be disengaged from the recess 26 for the P range, and the shift lever 12 cannot be shifted to a D range position other than the P range position. In the state described above,
When the brake is depressed, the power to the solenoid of the actuator 48 is cut off, and the shift lock plate 46 receives the urging force of the spring of the actuator 48 so as to rotate in the direction of arrow D, and this urging force is transmitted to the cam via the projection 50A. It is configured to transmit to the plate 50. At this time, a biasing force in the direction of arrow D of the shift lock plate 46 and a biasing force in the direction of arrow E trying to rotate itself act on the cam plate 50.
8 is transmitted to the grooved pin 20 in contact.

The force for urging the grooved pin 20 toward the tip end of the shift lever 12 (the force in the direction opposite to the arrow C) is
By setting the force sufficiently higher than the sum of the urging forces acting on the shift lock plate 46 and the cam plate 50, the state shown in FIG. 1 is maintained unless the knob button is operated. When the knob button is pressed in this state, the grooved pin 20 is pushed down in the direction of arrow C. Then, in conjunction with the operation of the grooved pin 20, the cam plate 50 rotates in the direction of the arrow E while bringing the connecting portion 58 into contact, and the protrusion 50A moves from the rotation blocking position of the shift lock plate 46. The protrusion 50
The shift lock plate 46 is rotated in the direction of arrow D while the guide surface 64 is in sliding contact with A, and the end portion 46A is rotated to the position shown in FIG.

In the state of FIG. 2, the grooved pin 20
Are disengaged from the recess 26 for the P range, so that the shift lever 12 can be rotated to perform a shift change operation for moving to another range position.

In the state shown in FIG. 2, the key lock cable 60 is moved by the rotation of the cam plate 50, so that the key interlock mechanism is in a state where the key cannot be removed.

When returning the shift lever 12 from the shift operation position other than the P range to the P range position, return the shift lever 12 to the P range position shown in FIG. 2 while pressing the knob button, and release the knob button. Then, by the urging force of the spring relating to the knob button, the knob button operates in the reverse manner to return to the state shown in FIG.

Next, the operation and operation of the forcible shift lock release mechanism in the shift lever device according to the present embodiment will be described. In the state of the shift lever device shown in FIG. 1, the shift lever 12 is shifted from the P range position to the other R, N, D, 2, L ranges without operating the keys and depressing the brake. When performing the operation, the push button 44 of the operation member 36 is pressed in the direction of arrow A as shown in FIG.

Then, the operating member 36 is rotated in the direction of arrow B about the shaft pin 38 to the position shown by the two-dot chain line in FIG. 3, while sliding the interlocking pin 42 in the long hole 40 thereof. The restricting member 34 is pulled up to a position shown by a two-dot chain line in FIG. In this state, the tip side of the tip portion 34A of the limiting member 34 is substantially at the same level as the R range side portion 28. Then, in this state, by pressing the knob button of the shift lever 12, the grooved pin 20 is lowered to the position shown by the solid line in FIG.
Move to any of the N, D, 2, and L shift range positions. In this way, the shift lock can be released and the shift lever 12 can be shifted even when there is no key, or when the key lock cable 60, the cam plate 50, the shift lock plate 46, or the actuator 48 does not move. Also, in this operation, the operation amount of the knob button can be made smaller than in the normal operation.

In order to return the shift lever 12 to the P range when the shift lever 12 is at a position other than the P range, the operating member 36 is operated as described above to move the limiting member 34 to the position indicated by the two-dot chain line in FIG. In this state, the shift lever 12 may be returned to the P range position. Thereafter, when the push button 44 of the operating member 36 is released, the restricting member 34 is lowered to its solid line position in FIG. 3 by its own weight or a spring (not shown), and accordingly, the operating member 36 is also moved to the solid line position in FIG. Return. In addition,
The excessive rotation of the operation member 36 upward is restricted by the upper stopper S2, and the distal end portion 34A of the restriction member 34 is prevented from moving above the same level as the R range side portion 28. In addition, the lower stopper S1 allows the restricting member 34
Is regulated so that the amount of protrusion downwards is constant.

Further, in the above-described embodiment, the structure in which the restricting member 34 of the detent plate 22 is moved has been described. However, the present invention is not limited to this structure.
2, the restricting member is configured to include a portion between the P range concave portion 26 and the R range side portion 28, and the R range side portion 2
8 and the limiting member is configured to include the N and D range sides 30, and the limiting member is configured to include the 2 and L range sides 32 and the like. It may be configured to be movable in a direction perpendicular to the direction. The entire detent member 22 may be configured to be movable as a limiting member.

Further, the restricting member 34 can be moved so that the operation of the grooved pin 20 is not restricted by the operating member 36. Therefore, the restricting member 34 is pivotally mounted on the detent plate 22 by pivoting. Or may be configured to move separately in a direction perpendicular to the side plane of the detent plate 22 or in a direction separating from the grooved pin 20.

[0044]

As described above, the shift lever device according to the present invention can forcibly release the shift lock by manual operation even in the shift locked state, and also manually releases the shift locked state and the like. Therefore, there is an excellent effect that the arrangement space of other members is hardly restricted and the space can be effectively used.
