Abstract

PROBLEM TO BE SOLVED: To provide easy operation by reducing operating force at a knob button at its pushing operation-terminating side in a shift lever. SOLUTION: Midway-pusing operating for a knob button 60 mounted on a shift lever 50 provides moving operation to a grouped pin 62 in the direction ejected from the recessed part 64A for the parking range of a detent hole 64. In operatioely associating with this, rotational movement is applied to a second operating member 68 and a first operating member 66 connected to the second operating member 68 through connecting means 74 to operate a key interlocking mechanism in a locked state. Then, in fully pushing the knob button 60, the connecting means 74 is released by rotationally moving the second operating member 68 with the first operating member 66 controlled by means of the reaction of the key interlocking mechanism under locked state. Finally, the second operating member 68 is rotationally moved with the comparatively low pushing operating force of the knob button 60. The grouped pin 62 is withdrawn from the recessed part 64A for the parking range to allow shift change action.

Is the arrow A further from the position of FIG.
In this case, only the second operation member 26 rotates in the direction of arrow A against the biasing force of the torsion coil spring 28,
The state shown in FIG. 12 is reached.

In the state shown in FIG. 12, the grooved pin 1
8 is sufficiently separated from the P range recess 20A, the shift lever 10 is tilted to perform a tilt operation to a desired shift range position. When the shift lever 10 is tilted and returned to the P range position, the grooved pin 18 hits the arm 26A during the operation, and the second operating member 26
While rotating in the direction of arrow A, it enters the entrance of the P range recess 20A, and returns to the P range state shown in FIG.

[0013]

In the above-described shift lever device, when performing a shift change operation, a part of the operation of the shift lock mechanism and the operation of the key interlock mechanism are depressed by pushing the knob button 16 of the shift lever 10. It is performed by operating.

Referring to the operating force for pushing the knob button 16, as shown in FIG. 13, as a part of the operating force, the knob button 16 is projected from the shift lever knob 14 by a predetermined amount, and the grooved pin 18 is moved to the shift lever. The biasing force F1 of the return spring for returning the shift lever knob 14 to a predetermined position on the shift lever knob 14 side operates throughout the operation. In addition, during the operation from FIG. 10 to FIG.
A resistance force F2, such as a frictional force, for rotating the operation member 24, sliding the key lock cable 30, and further sliding the stopper 34 is applied. In addition, during the operation from FIG. 11 to FIG. 12, the urging force F3 of the torsion coil spring 28 urging the second operation member 26 always acts during the operation.

Therefore, the knob button 16 is moved from FIG.
The operating force for the push operation up to state 2 is approximately the operating force FT which is the resultant of the urging force F1, the resistance force F2, and the urging force F3. As can be seen from FIG.
Increases further from the half of the operation stroke of pushing the knob button 16 to the pushing end side (the pushing position of the knob button which can be moved from the P range to another range, the position from P to R in FIG. 13). For this reason, the driver
When the knob button 16 is pressed while the shift lever knob 14 is being held, a large force must be applied during the operation at the end of the push, which is harder to apply than the operation at the beginning of the push of the knob button 16, and the operation becomes difficult. Was.

In consideration of the above facts, the present invention reduces the operating force at the end of the push operation of the knob button when operating the key interlock mechanism by pushing the knob button of the shift lever. It is an object of the present invention to provide a new shift lever device that is easy to operate.

[0017]

According to a first aspect of the present invention, there is provided a shift lever device capable of performing a shift operation from a parking shift range position to each of the other shift range positions, and a shift lever mounted on the shift lever. When the grooved pin is moved by the moved knob button, the detent hole in which the grooved pin is inserted and at least a parking range recess is formed, and the shift lever is at a parking shift range position, the knob button is operated. A second operation member which is rotated by interlocking with the operation of the grooved pin by receiving the grooved pin moved by the groove portion, and a first operation in which one end of a key lock cable which is interlocked with a key interlock mechanism is connected A member, the first operation member, and the second operation member And a connection means for releasing the connection between the two when a relative rotation power of a predetermined value or more is applied, wherein the key interlock mechanism is locked when the knob button is pressed halfway. The state shifts to a state where the movement of the first operating member is stopped by the reaction force from the key interlock mechanism, and when the knob button is further pushed to the end, the connecting means is released and the second operating member is released. Is rotated by a relatively weak pressing force of the knob button, so that the grooved pin comes out of the parking range recess.

With the above configuration, when the shift lever is in the parking range position and the knob button is started to be pressed, the grooved pin moves in conjunction with the push operation. Then, the second operating member accommodating the grooved pin in the groove and the first operating member connected to the second operating member by the connecting means rotate integrally, and the key is pulled out of the key interlock mechanism via the key lock cable. Operate so that it is locked so that it cannot be locked.

At this time, the operation of the key interlock mechanism is completed, and the operation of the first operating member connected via the key lock cable is stopped. Further, when the knob button is pushed relatively strongly, the connecting means is released by the rotating force applied to the second operation member. Thereafter, by pushing the knob button relatively weakly, the second operation member is further rotated with respect to the stopped first operation member, and the grooved pin in the groove is separated from the concave portion in the detent hole.
In this state, the shift lever is tilted to rotate to a desired shift range position.

The above operation is performed at least in a key interlock operable state of the key interlock mechanism. Also, when the shift lever is returned to the parking range position, when the hand is released from the knob button, the operation returns to the initial state by the urging force of the return spring in an operation opposite to that described above.

According to a second aspect of the present invention, in the shift lever device according to the first aspect, the connecting means includes the first,
An engaging head provided on the other operating member can be inserted and withdrawn by an urging force into an engaging hole formed in one of the second operating members. Is inserted into the engaging hole, and in a disconnected state, the engaging head is pulled out from the engaging hole.

With the above construction, when a force equal to or more than a predetermined value for relatively rotating the first operating member and the second operating member is applied between the first operating member and the second operating member, the first operating member and the second operating member are engaged against the urging force of the spring. The head is detached from the engagement hole, and the first operation member and the second operation member are separated.
Release the connection with the operation member. Also, when the position of the engaging head and the engaging hole portion match, by the urging force of the spring,
The engaging head is inserted into the engaging hole to enter the engaged state.

At the position corresponding to the parking shift range (P), the detent hole 64 is formed with a long groove-shaped P range recess 64A having a width slightly larger than the diameter of the grooved pin 62. The P range recess 64A is formed in the P range recess 64A. Is the shift lever 50
Is in the P range position, the grooved pin 62 is inserted. (Structure of First and Second Operation Members) A first operation member 66 and a second operation member 68 are coaxially mounted on the machine frame 54 of the shift lever device by the same shaft pin 70. The first operation member 66 is formed by forming a plate material into a substantially oval shape.
A shaft pin 70 is axially inserted near one end thereof, and one end of a key lock cable 72 is axially mounted near the other end.

The second operating member 68 is a deformable plate-shaped member as shown in FIGS. 1 to 3, and a predetermined portion thereof is axially fixed by a shaft pin 70. As shown in the drawing, the first operating member 6 is moved from the shaft attachment portion of the shaft pin 70 in the second operating member 68.
A connecting means 74 is provided at a portion of the key lock cable 72 extending so as to overlap the shaft attachment portion side. The connecting means 74 connects the first operating member 66 and the second operating member 68 to rotate integrally with the shaft pin 70 as an axis, and moves the first operating member 66 and the second operating member 68 relative to each other. When a force equal to or more than a predetermined value in the direction of the actual rotation is applied, the connection between the two is released. (Structure of Connecting Means) Such connecting means 74 can be structured as shown in FIG. The connecting means 74 includes a case 76 provided at a predetermined portion of the second operating member 68.
A storage portion 78, which is a cylindrical concave portion, is formed therein. A compression coil spring 80 is inserted into the bottom side of the storage portion 78, and further, a hemispherical head is provided so as to be able to protrude outward from an opening of the storage portion 78. The mooring head 82 has a cylindrical shape and is configured to protrude by a predetermined amount by the urging force of the spring 80.

At the same time, an engaging hole portion 84 which is a circular concave portion through which the engaging head 82 can be inserted and withdrawn is provided at a portion corresponding to the storage portion 78 in the first operation member 66. Further, in order to make it possible to favorably disengage the engaging head 82 and the engaging hole 84, the engaging hole 84

When the first operating member 66 and the second operating member 68 are in a predetermined positional relationship, the positions of the engaging head 82 and the engaging hole 84 match, and the engaging head 82 4 is inserted into the engagement hole portion 84 by the urging force of the spring 80, as shown in FIG. In the state shown in FIG. 4, when a force is exerted on the first operating member 66 and the second operating member 68 to relatively rotate around the shaft pin 70, the rotational operating force is less than a predetermined value. In this case, the fastening head 82 is inserted from the storage portion 78 into the fastening hole 84 so that the fastening head 82 is
The first operating member 66
The relative operation between the second operating member 68 and the second operating member 68 is stopped, and the locked state in which the two integrally rotate around the shaft pin 70 is maintained.

When a rotation operation force equal to or more than a predetermined value for relatively rotating the first operation member 66 and the second operation member 68 is applied, the engagement hole portion 84 is turned off. Since the inner peripheral surface strongly contacts the surface of the hemispherical head of the mooring head 82 and slides, the mooring head 82 is pushed into the storage portion 78 against the urging force of the spring 80. Since the engaging head 82 comes out of the engaging hole 84 and the engagement of the connecting means 74 is released, the first operating member 66 and the second operating member 68 can be relatively rotated. . The connecting means 7
The configuration 4 is not limited to the above-described configuration, and can take various configurations, for example, using a magnet. Further, in the present specification, when the state of disconnection is referred to, a state in which the resistance force that the moving force of the second operation member 68 receives by the first operation member 66 sharply and extremely lower than that in the connected state is referred to. Shall be.

As shown in FIG. 1, a portion of the second operating member 68 extending from the shaft pin 70 to the side of the detent hole 64 has a groove 69 into which the grooved pin 62 is inserted, and the grooved pin 62 is slid into the groove 69. Smooth guide sides 71 and 73 for moving guide are formed.

As shown in FIGS. 1 to 4, the first operating member 66 is not rotated around the shaft pin 70 in the direction opposite to the arrow C from the state shown in FIG. ,
The first operation member 66 is provided with a protrusion 66A, and the machine frame 54 is provided with a restriction portion 54A which is formed in a predetermined arc shape and into which the protrusion 66A is slidably inserted, or a concave groove. The rotation range of the first operation member 66 is limited. In addition,
This configuration may be a stopper pin that abuts on the peripheral portion of the first operation member 66 to stop. (Configuration of Key Interlock Mechanism) As illustrated in FIGS. 1 to 3, the key interlock mechanism is configured to be operated by a key lock cable 72 whose one end is supported by the first operation member 66. . This key interlock mechanism includes a rotor 90 inside a key cylinder 88,
A slider 92 is mounted. The key cylinder 88 includes a front circular rotor portion 88A and a quarter thereof.
And a slider portion 88B integrally extended from the circular portion into a front rectangular shape. At the center of the rotor portion 88A, a shaft member 94 that rotates in conjunction with a rotation operation of a key of the vehicle is mounted. To the shaft member 94, a main part of a sector of the sector-shaped key rotor 90 is fixed.
A is mounted so as to be able to rotate inside A. Further, a chord portion extending in the radial direction of the key rotor 90 is formed as a regulating side 96 that contacts the slider 92, and a main portion of the sector is formed in a small circular shape and serves as a position limiting portion 98 extending from the regulating side 96. .

The slider portion 88B of the key cylinder 88 is formed in a cylindrical shape, and a slider 92 is slidably mounted in the slider portion 88B. This slider 9
Step 2 is a range from the position on the slider portion 88B side shown in FIG. 1 to the position where the movement of the key rotor 90 in the rotor portion 88A shown in FIG. The other end of the key lock cable 72 is connected to the slider 92. The key lock cable 7 is linked with the predetermined rotation of the first operation member 66.
2 is pushed, the slider 92 is slid in the key cylinder 88 and the key lock cable 72
When a full stroke pushing operation is performed, the slider 92 abuts on the position limiting portion 98 of the key rotor 90 to limit the movement. The key interlock mechanism described above may use a key interlock mechanism that is generally used. (Structure of shift lock mechanism) The shift lever device described above is not shown as a part of the shift lock mechanism, but operates in association with a commonly used actuator and a part of the key interlock mechanism. A lock member is mounted. As shown in FIG. 1, the locking member operating in association with this actuator includes a grooved pin 6.
Key is inserted into the key cylinder 88 and the LOCK,
Or, the lock member that is operated in association with the operation of the actuator and part of the operation of the key interlock mechanism unless the brake is depressed and turned to the ACC, ON, or START position side from the OFF position is in the P range. Recess 64
Block the exit of A and prevent the grooved pin 62 from moving out of the P range recess 64A and moving to another range,
The grooved pin 62 is configured to be held in the P range recess 64A. (Operation and Operation) Next, the operation and operation of the shift lever device according to the first embodiment configured as described above will be described.

When the vehicle is in a parking state as shown in FIG. 1, the shift lever 50 is in the parking shift range (P) position, the grooved pin 62 fits in the P range recess 64A, and the P range recess 64A. Is closed by the lock member, and the grooved pin 62 is prevented from coming out of the P-range recess 64A, so that the shift lever 50 rotates from the parking shift range (P) position in the arrow C direction. It is in the locked shift lock state.

In this shift locked state, even if the driver tries to push the knob button 60 of the shift lever 50,
Since the locking member (not shown) prevents the grooved pin 62 from being detached from the P-range concave portion 64A, the operation of pushing the knob button 60 cannot be performed. For this reason, the grooved pin 62 is stopped in the recess 64A for the P range, so that the shift lever 50 is moved to another range (R, N,
(D, 2 and L ranges).

In this state, the rotor 90 of the key cylinder 88 is at the key extraction position (LOCK) where it enters the slider portion 88B, and the key can be freely inserted and removed.

Next, when releasing the shift lock and performing a shift change operation of the shift lever 50, first, the driver inserts the key into the key cylinder and turns the key to turn the LO.
From CK or OFF, ACC, ON, or START
It turns to the position side. When the brake is further depressed, the lock member is disengaged from the P-range recess 64A in relation to the actuator of the shift lock mechanism (not shown), and the grooved pin 62 comes out of the P-range recess 64A. In this state, when the knob button 60 is pressed against the urging force of the return spring of the shift lever 50,
In conjunction with this, the grooved pin 62 moves the shift lever 50
To the shaft cylinder 52 side, which is the base end of.

During the operation of the grooved pin 62, while the grooved pin 62 moves from the state shown in FIG. 1 at the innermost part of the P-range recess 64A to the state shown in FIG. Since the second operating member 68 and the first operating member 66 are connected by the connecting means 74, they both rotate integrally in the direction of arrow C. Then, according to the turning operation of the first operation member 66,
The key lock cable 72 is operated, and is pushed forward until the slider 92 shown in FIG. That is, in the state shown in FIG. 2, the arrow C of the first operating member 66 connected via the key lock cable 72 to the slider 92 stopped by the position restricting portion 98.
Further rotation in the direction is restrained.

From the state shown in FIG.
When 0 is pressed, the grooved pin 62 moves toward the shaft cylinder portion 52 of the shift lever 50, so that the second operating member 68 tries to rotate further around the shaft pin 70 in the direction of arrow C. Since the first operating member 66 is restrained, a force for relative rotation acts between the first operating member 66 and the second operating member 68, and when the relative rotating force exceeds a predetermined value, the connecting means 74 The engaging head 82 is disengaged from the engaging hole 84 against the urging force of the spring 80, the engagement between the first operating member 66 and the second operating member 68 is released, and the second operating member 68 is free to rotate. For this reason, the grooved pin 62 moves the second operation member 68 to the arrow C.
While rotating in the direction, it moves to the position shown in FIG.

When the driver tilts the shift lever 50 in this state, the grooved pin 62 comes out of the groove 69, moves in the detent hole 64, and moves to another desired shift range (R, N, D, 2, L range). ).

In the state shown in FIGS. 2 and 3, the key lock cable 72 is pushed full stroke.
When the slider 92 hits the restricting side 96 of the rotor 90, the rotor 90 is moved to the key extraction position (LOCK) in FIG. 1.
Since the rotation of the key is restricted, the key is in a key interlock state where the key cannot be pulled out.

Next, when the shift lever 50 is in another shift range (R, N, D, 2, L range), and when the shift lever 50 is to be returned to the parking shift range, the driver has pressed the knob button 60. In this state, the shift lever 50 is tilted to the parking shift range (P). As a result, the grooved pin 62 enters the groove 69 as shown in FIG. 3, and the user releases the knob button 60 in this state. Then, the grooved pin 62 is moved toward the shift lever knob 58 of the shift lever 50 by the urging force of the return spring, and is accommodated in the deepest portion in the P range recess 64A. At this time,
When the grooved pin 62 moves from the position in FIG. 3 in the detent hole 64 to the position in FIG. 2 near the entrance of the P-range recess 64A, the second operation member 68 rotates in the direction opposite to the arrow C. Then, when the state shown in FIG.
The engaging head 82 enters the engaging hole 84 by the urging force of the spring 80, and the first operating member 66 and the second operating member 6
8 is engaged.

Thereafter, the grooved pin 62 moves from the state shown in FIG. 2 to the state shown in FIG. 1 to the shift lever knob 58 side of the shift lever 50, and the first operating member 68 is engaged with the second operating member 68 by the connecting means 74. The operation member 68 rotates integrally with the operation member 68 in a direction opposite to the arrow C. At this time, the slider 92 interlocked with the pivoting operation of the second operation member 68 via the key lock cable 72 comes off the regulating side 96 and enters the slider portion 88B, so that the rotor 90 is pulled out as shown in FIG. The key interlock is released, in which it is free to rotate to the possible position (LOCK). When the second operating member 68 is rotated to the state shown in FIG. 1, a lock member that operates in association with the operation of an actuator or the like (not shown) closes the outlet of the P-range recess 64A, and the grooved pin 62 moves to the P-range. The shift lock state is established in which movement from another concave portion 64A to another range is restricted.

It should be noted that the shift lock release from FIG.
When returning from the key interlock state to the shift lock state and the key interlock release state of FIG.
When the operating member 66 and the second operating member 68 are integrally rotated in the direction of arrow C due to the friction of the connecting means 74 in the released state, the protrusion of the first operating member 66 during the rotation operation. 6
6A hits the end of the restricting portion 54A and the first operating member 66
After that, only the second operation member 68 is rotated, and the engaging head 82 is aligned with the engaging hole 84, and is inserted therein by the urging force of the spring 80 and connected. Means 74
Is engaged. (Explanation of the Operating Force of the Knob Button) Next, the shift lever 5 is shifted from the above-described state shown in FIGS. 1 to 3 to release the shift lock and enter the key interlock state.
The pushing operation force on the 0 knob button 60 will be described with reference to FIG.

When operating the knob button 60, the knob button 60 is urged to project from the shift lever knob 58 by a predetermined amount, and the grooved pin 62 is returned to a predetermined position on the shift lever knob 58 side of the shift lever 50. The biasing force W1 of the return spring for biasing the knob button 60 works throughout the entire operation of the push operation of the knob button 60 during the operation.

Also, as shown in FIGS. 1 and 2, the second operation member 68 is pressed while the knob button 60 is pressed to shift the key interlock from the unlocked state to the key interlocked state. The first operating member 66 is rotated in the direction of arrow C via the key lock cable 72, and an operating resistance force W2 such as a so-called cable drag resistance when the slider 92 slides via the key lock cable 72 acts.

Further, in the state of FIG. 2, since the slider 92 hits the position restricting portion 98 and is stopped, the first operating member 66 connected via the key lock cable 72 is in the stopped state. Therefore, the pressing operation force of the knob button 60 is a force for rotating the second operation member 68 in the direction of arrow C via the grooved pin 62. This rotating power is generated by the connecting means
When the force exceeds the predetermined peak release force W3, the engaging head 82 of the connecting means 74 is detached from the engaging hole 84.

Thereafter, the second operating member 68 is rotated in the direction of arrow C against the operating resistance W4 such as the resistance of the engaging head 82 sliding on the side surface of the first operating member 66, as shown in FIG. The shift lock release state shown in FIG.

As described above, the pressing force of the knob button 60 is the operating force WT as a resultant of the urging force W1, the operating resistance W2, the releasing force W3, and the operating resistance W4.

When the operating force WT of the knob button 60 of the shift lever device of the present embodiment shown in FIG. 5 is compared with the operating force FT of the conventional knob button 16 shown in FIG. In the section from 1 (FIG. 10) to FIG. 2 (FIG. 11), both the operating force WT and the operating force FT act equally.

Next, FIG. 2 (FIG. 11) to FIG. 3 (FIG. 12)
, The operating force WT temporarily increases,
Thereafter, the force suddenly decreases, becomes a resultant force of the urging force W1 and the operation resistance force W4 which is a slight force, and changes at a relatively weak value of the operation force WT. In contrast, the conventional operating force FT
Changes gradually to a large value at a time, and then increases proportionally without decreasing.

Therefore, according to the present embodiment, the operation force WT is temporarily increased when the key interlock corresponding to the middle position of the stroke until the knob button 60 is pushed down and the operation is completed is completed. Since the operating force can be greatly reduced, the driver does not need to apply a strong force to the finger near the end of the pushing operation of the knob button 60, so that the operation can be performed easily.
