Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention 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 longitudinal direction of the vehicle to shift the automatic transmission. In this type of shift lever device, the operation direction of the shift lever is set to the vehicle front-rear direction. For example, when the shift lever is selected in the P shift range, the shift lever is simply moved to the rear direction of the vehicle. Thus, the shift operation to the R shift range is possible.

By the way, in such a shift lever device, a shift lock mechanism is required which enables the shift operation of the shift lever only under a specific condition, and the shift from the P shift range to the R shift range as described above. The operation needs to be restricted in some way.

In this case, for example, by providing an electric actuator such as a solenoid or a shift controller in the vicinity of the shift lever, when the shift lever is operated from the P shift range to the R shift range, the actuator is operated unless the brake is operated. R is engaged with the shift lever
There has been proposed a shift lever device configured to prevent a shift operation to a shift range and prevent an ignition key from being removed unless the shift lever is positioned in the P shift range.

However, in the shift lever device provided with such an electric shift lock mechanism, the solenoid and the shift controller are expensive and there is a drawback that the cost is high as a whole, and further measures for this are desired. It was rare.

On the other hand, there has been proposed a shift lever lock device having an L-shaped lock member provided in the vicinity of the shift lever, and the lock member is connected to an ignition key portion via a wire (Japanese Patent Laid-Open No. 4-119252).
Issue).

In this type of shift lever lock device, when the shift lever is in the P shift range, the lock member engages with the shift lever to prevent a shift operation to a shift range other than the R shift range. It is a composition.

However, in such a shift lever lock device having a simple structure in which the movement of the shift lever is restricted by such an L-shaped lock member, the device becomes large and a large arrangement space is required. In the shift lock state in which the lock member is engaged with the shift lever to prevent the shift operation to the shift range other than the R shift range, the shift lock state is released without operating the ignition key portion. In the case (when the shift lock is forcibly released manually), this is impossible, and there is room for improvement in this respect as well.

[0009]

SUMMARY OF THE INVENTION In consideration of the above facts, the present invention has a simple structure to ensure further safety,
An object of the present invention is to obtain a shift lever device that can be surely put into a shift lock state under a specific condition and can be manually released from the shift lock state.

Further, when the lever is selected in the P shift range, the engaging portion of the stopper engages with the grooved pin of the lever, and the stopper and the cam are integrated by the upward movement of the grooved pin by the urging force. And operates in one direction (in this state, rotation of the cam and the stopper in the other direction is prevented), and the groove pin is prevented from moving downward in the axial direction by a button operation. As a result, the grooved pin cannot ride over the detent groove of the detent plate, and is prevented from moving to a shift range other than the P shift range, resulting in a shift lock state. On the other hand, in this case, when the key and the brake are operated, the cam and the stopper integrated with the cam can be rotated in the other direction, and the movement preventing state of the grooved pin by the stopper (engaging portion) is released, and the button operation is performed. This enables the grooved pin to move downward in the axial direction. As a result, the lever can be moved to a shift range other than the P shift range, and the shift lock is released.

In a shift lock state in which the cam and the stopper are prevented from rotating in the other direction and the groove pin is prevented from moving downward in the axial direction by a button operation, the cam connected to the ignition key portion is rotated. Without releasing the shift lock state (when manually forcibly releasing the shift lock), when the force release button provided on the vehicle body is operated, the claw of the stopper is released from the engagement with the cam. The stopper can be rotated independently of the cam. Therefore, it is possible to move the grooved pin downward in the axial direction by operating the button.

The shift operation of the lever is restricted unless the grooved pin is moved downward in the axial direction by the button operation.

Furthermore, when the lever is selected in the P shift range, the stopper and the cam rotate integrally in one direction so that the slit of the stopper engages with the guide pin of the lever (in this state, the cam is rotated). And the stopper is prevented from rotating in the other direction), the movement of the lever to a shift range other than the P shift range is blocked, and the shift lock state is set. On the other hand, in this case, when the key and brake are operated, the cam and the stopper integrated with the cam can be rotated in the other direction, and the cam and the stopper are moved in the other direction by moving the grooved pin downward in the axial direction by the button operation.

1 is a perspective view showing the structure of a main portion of a shift lever device 10 according to a first embodiment of the present invention. The shift lever device 10 is shown in FIGS.
The configuration of the main part of is shown in a side view.

In the shift lever device 10, the shift lever 12 is rotatably arranged. A grooved pin 14 is provided on the shift lever 12 so as to project to the outside. The grooved pin 14 is movable along a slide hole 16 formed along the axial direction of the shift lever 12. Further, the grooved pin 14 is connected to a detent rod 18 arranged inside the shift lever 12. The detent rod 18 is moved by operating a knob button (not shown), and the grooved pin 14 is moved.
It is a structure that can be moved. The detent rod 18 is constantly urged upward in the axial direction of the shift lever 12 by a spring (not shown),
For this reason, the grooved pin 14 normally has a slide hole 16
It is located near the upper end of the.

The shift lever 12 having the above structure is connected to an automatic transmission (not shown) via a rod, a cable or the like, and the transmission can be shifted by operating it back and forth.

A detent plate 20 is arranged on the side of the shift lever 12 (grooved pin 14). A detent groove 22 is formed in the detent plate 20, and one end of the grooved pin 14 is inserted therein. The detent groove 22 is a shift position of the shift lever 12, that is, “P”, “R”,
The surrounding wall is continuously bent in an uneven shape in association with each of the shift ranges of "N", "D", "2", and "L", and the unevenness causes the grooved pin 14 to move, that is, the shift lever. A configuration capable of restricting movement of the shift levers 12 to other adjacent shift ranges (in other words, unless the grooved pin 14 moves toward the lower end portion of the slide hole 16 and rides over the unevenness of the detent groove 22). Is a configuration in which movement to other adjacent shift ranges is restricted). In this case, in particular, the shift lever 1
When 2 is in the “P” shift range, it engages with the grooved pin 14 located in the vicinity of the upper end of the slide hole 16 (moving upward in the axial direction of the shift lever 12), and the shift lever 12 moves. It is designed to prevent movement to the "R" shift range. Therefore, in this state, unless the grooved pin 14 moves toward the lower end portion of the slide hole 16, the grooved pin 14 does not get over the unevenness of the detent groove 22.

Detent plate 2 of shift lever 12
A lock device 24 is arranged on the side opposite to 0.

The lock device 24 includes a cam 26 and a stopper 2.
8 is provided. The cam 26 is formed in a substantially rectangular plate shape, and one end corner portion is rotatably supported by the bracket 32 by the support shaft 30. A locking projection 34 is formed on the upper end portion of the front surface of the cam 26 (on the shift lever 12 side), and a pressing projection 36 is formed on the center portion.

On the other hand, the stopper 28 is formed in a substantially triangular plate shape, and one end corner portion thereof is supported by the cam shaft 26 by the support shaft 30.
It is rotatably supported by the bracket 32 coaxially therewith. An arm portion 38 is integrally extended to the upper end portion of the stopper 28, and a claw portion 40 that is convex upward is formed at the tip of the arm portion 38. The arm portion 38 has elasticity, and the claw portion 40 corresponds to the locking projection 34 of the cam 26 and can be engaged with the locking projection 34. Stopper 2
The stopper 28 and the cam 26 are configured to rotate integrally with each other when the claw 40 of No. 8 is engaged with the locking projection 34 of the cam 26. Further, the arm portion 38 of the stopper 28 corresponds to the forced release button 42 (see FIG. 4) provided on the vehicle body, and is pressed from above by the forced release button 42 and elastically deformed, so that the claw portion 40 is formed. The engagement with the locking projection 34 can be released. In the normal state, the claw portion 40 of the stopper 28 is engaged with the locking projection 34 of the cam 26, and the stopper 28 and the cam 26 are in a state of rotating integrally.

Further, a support protrusion 44 is formed at the center of the surface of the stopper 28 (on the shift lever 12 side). The support protrusion 44 corresponds to the pressing protrusion 36 of the cam 26, and the leaf spring 48 is attached by the screw 46. The leaf spring 48 is provided on the claw portion 4 of the stopper 28.
When 0 is engaged with the locking projection 34 of the cam 26 and the stopper 28 and the cam 26 are integrated, the pressing projection 36 of the cam 26 is pressed. Therefore, the stopper 28 and the cam 26 are separated and independent, and are always urged in a direction in which they are separated from each other. As a result, the claw portion 40 of the stopper 28 is moved to the cam 2
When the stopper 28 and the cam 26 are integrated with each other by engaging with the locking projection 34 of No. 6, there is no rattling of both.

Further, an engaging portion 50 is formed at the lower end corner of the stopper 28. The engaging portion 50 is formed in a beak shape, and as shown in detail in FIGS. 2 to 4, the grooved pin 1 of the shift lever 12 located in the “P” shift range.
4 and the stopper 28 is downward (see arrow A in FIG. 2).
Direction), the shift lever 12 is in the “P” position.
The grooved pin 14 enters the engaging portion 50 when the shift operation is performed in the shift range.

A torsion coil spring 52 is wound around the support shaft 30 which supports the cam 26 and the stopper 28 having the above-described structure. One end of the torsion coil spring 52 is locked to the stopper 28, and the other end is attached to the bracket 32.
Is locked to. As a result, the stopper 28 (the claw portion 4
When 0 is engaged with the locking protrusion 34, the cam 26 is always biased in the direction of arrow A in FIG. 2 and is in contact with the bent portion 54 of the bracket 32. The biasing force of the torsion coil spring 52 is the same as that of the detent rod 18 described above.
It is set to be smaller than the biasing force of the spring that biases the (grooved pin 14) upward in the axial direction of the shift lever 12.

On the other hand, the back side of the cam 26 (the shift lever 1
A connecting protrusion 56 is formed at a corner portion (on the side opposite to 2) so that the tip end portion of the key interlock cable 58 is connected. Therefore, the key interlock cable 5
The cam 26 is configured to rotate around the support shaft 30 in synchronism with the gear 8.

The other end of the key interlock cable 58 is connected to a solenoid-incorporated cable lock device (not shown). This cable lock device operates by pushing in the key interlock cable 58 to prevent the key interlock cable 58 from moving, and further releases the blocked state by a key and brake operation to release the key interlock cable 58. Enable the movement of.

As a result, by operating the knob button, the grooved pin 14 moves toward the lower end of the slide hole 16 to get over the unevenness of the detent groove 22 and the shift lever 12 is pushed.
Is operated to the “P” shift range, the grooved pin 14 enters the engaging portion 50, and further, the engaging portion 50 of the stopper 28 is pressed against the grooved pin 14 by the upward movement of the grooved pin 14 due to the urging force of the grooved pin 14. Stopper 28 and cam 26 are upward (in the direction of arrow B in FIG. 2).
The key interlock cable 58 is pushed in by pushing the key interlock cable 58, and the cable lock device operates to move the key interlock cable 58, that is, the cam 26 and the stopper 2.
It is configured such that the rotation of the cam 8 and the stopper 28 can be rotated by preventing the rotation of the cam 8 and further canceling the blocked state by operating the key and the brake.

Next, the operation of the first embodiment will be described. In the shift lever device 10 having the above configuration, the shift lever 12
The transmission can be shifted by operating the front and back. In this case, the movement of the shift lever 12 is restricted by the detent plate 20.

That is, when the shift lever 12 is selected to the "N" shift range, the grooved pin 14 of the shift lever 12 is placed in the detent groove 22 of the detent plate 20 formed corresponding to the "N" shift range. When the shift lever 12 is engaged, the shift lock state (so-called "R" inhibit) in which the movement of the shift lever 12 from the "N" shift range to the "R" shift range is blocked is entered. Therefore, the shift operation of the shift lever 12 is restricted unless the knob button of the shift lever 12 is operated to push down the grooved pin 14 to overcome the unevenness of the detent groove 22.

In this state (“R” inhibit state), the grooved pin 14 is prevented from moving in the “R” shift range direction corresponding to the detent groove 22 when it is selectively moved to the “N” shift range. Therefore, the shift lever 12 can be moved in the “D” shift range direction and the “2” shift range direction.

Furthermore, when the shift lever 12 is selected to the "P" shift range, the grooved pin 14 enters the engaging portion 50 of the stopper 28 as shown in FIG.
Further, the engaging portion 50 of the stopper 28 is moved by the upward movement of the grooved pin 14 to cause the grooved pin 14 to move.
Then, the stopper 28 and the cam 26 are rotationally moved upward (in the direction of arrow B in FIG. 2) by being pressed by (the state shown in FIG. 3).
As a result, the key interlock cable 58 is pushed in to activate the cable lock device, and the key interlock cable 58 moves, that is, the cam 26 and the stopper 2.
The rotation of 8 is blocked. Therefore, in this state, the grooved pin 14 is held by the engagement portion 50 of the stopper 28, and the downward movement of the grooved pin 14 in the axial direction by the button operation is prevented. As a result, the grooved pin 14 cannot ride over the unevenness of the detent groove 22 of the detent plate 20, and the shift lever 12 moves to a shift range other than the "P" shift range (movement in the "R" shift range direction). ) Is blocked (so-called “P” range shift lock).

On the other hand, when the key and the brake are operated after the shift lever 12 is selected to the shift range of "P" and is in the shift lock state, the cam 26 and the stopper 28 integral therewith are prevented from rotating. Is released and downward (Fig. 3
It is possible to rotate in the direction of arrow A). For this reason, the movement preventing state of the grooved pin 14 by the engaging portion 50 of the stopper 28 is released, and the grooved pin 1 is operated by the button operation.
4 can be moved downward in the axial direction. This allows
The shift lock is released so that the shift lever 12 can be moved to a shift range other than the "P" shift range, and the groove pin 14 is moved downward in the axial direction as shown in FIG. Can be operated.

A shift lock state in which the cam 26 and the stopper 28 are prevented from rotating downward (direction of arrow A in FIG. 3) and movement of the grooved pin 14 in the axial direction downward by button operation is prevented (state shown in FIG. 3). In order to release the shift lock state without manually rotating the cam 26 connected to the ignition key section (when manually forcibly releasing the shift lock), as shown in FIG. When the release button 42 is operated, the arm portion 38 of the stopper 28 is pressed from above and elastically deformed, and the claw portion 40 is released from the engagement with the locking projection 34 of the cam 26. Therefore, the stopper 28 can be rotated independently of the cam 26, and the groove pin 14 can be moved downward in the axial direction by a button operation. Therefore, by moving the grooved pin 14 downward in the axial direction, only the stopper 28 separates from the cam 26 and rotates downward (in the direction of arrow A in FIG. 4) accordingly, except for the "P" shift range of the shift lever 12. The shift lock release state (the state shown in FIG. 4) in which it is possible to move to another shift range is set.

As described above, in the shift lever device 10 according to the first embodiment, the grooved pin 14 is operated by the button operation.
Shift operation becomes possible by moving the shaft downward in the axial direction. Furthermore, in the "P" shift range, the cam 2
6 and the stopper 28 operate to enter a locked state or an unlocked state that prevents the grooved pin 14 from moving downward in the axial direction by a button operation. That is, with the mechanical and simple structure of the detent plate 20, the cam 26, and the stopper 28, it is possible to ensure the shift lock state under a specific condition while ensuring further safety. Further, the shift lock state can be manually forcibly released.

Next, a second embodiment of the present invention will be described. The parts that are basically the same as those in the first embodiment have the first
The same reference numerals as in the embodiment are given and the description thereof is omitted.

5 to 7 are side views showing the construction of the main part of the shift lever device 60 according to the second embodiment of the present invention.

In the shift lever device 60, the lock device 6
2 are arranged. The lock device 62 includes a cam 64 and a stopper 66. The cam 64 has the same structure as the cam 26 of the lock device 24 of the shift lever device 10 according to the first embodiment described above.

On the other hand, the stopper 66 has basically the same structure as the stopper 28 in the lock device 24 of the shift lever device 10 according to the first embodiment described above, but instead of the engaging portion 50 in the stopper 28, A guide portion 68 is provided. The guide portion 68 extends largely downward than the grooved pin 14 of the shift lever 12 and has a slit 70 formed therein. This slit 70
Is constituted by a guide region 70A and a locking region 70B, and further, the tip of a guide pin 72 projectingly fixed to the shift lever 12 is slidably inserted. The guide region 70A of the slit 70 is formed in an arc shape centered on the rotation center X of the shift lever 12 and having a radius between the rotation center X and the guide pin 72. Therefore, when the guide pin 72 is located in the guide area 70A, the shift lever 12 can move without being restricted by the slit 70 and the guide pin 72. On the other hand, the locking area 70B of the slit 70
Is formed in an arc shape centered on the axis of the support shaft 30 and having a radius between the axis of the support shaft 30 and the guide pin 72. Therefore, when the guide pin 72 is located in the guide area 70A, the shift lever 12 is restrained from moving by being restrained by the slit 70 and the guide pin 72, and the guide portion 68 (stopper 66) is moved by the slit 70 and the guide pin. It is possible to rotate around the support shaft 30 without being restricted by 72.

In this case, the shift lever 12 is "L".
The guide pin 72 is located in the guide region 70A of the slit 70 in the shift range to the "R" shift range, and when the shift lever 12 is selected in the "P" shift range, the guide pin 72 is engaged with the slit 70. Dimensions and the like of each part are set so as to enter the stop region 70B.

Further, the guide portion 68 of the stopper 66, in which the slit 70 having the above-described structure is formed, can be engaged with the grooved pin 14 of the shift lever 12 at the upper edge thereof, and the grooved pin 14 can be operated by operating the knob button.
Is pressed by the downward movement of the shaft and is rotated around the support shaft 30. In this case, when the shift lever 12 is positioned in the "P" shift range and the grooved pin 14 is positioned above, the guide pin 72 is positioned in the locking region 70B of the slit 70 as described above, and the grooved pin 14 is moved by operating the knob button. At the time when the groove 66 is moved to the lower side and the stopper 66 is rotated accordingly and the grooved pin 14 is located at the lowest position, the guide pin 72 moves the boundary portion (the bent portion) between the locking region 70B and the guide region 70A of the slit 70 as shown in FIG. ), The dimensions of each part are set so that the lock area 70B can enter the guide area 70A.

A torsion coil spring 74 is wound around the support shaft 30 that supports the cam 64 and the stopper 66 having the above-described structure. One end of the torsion coil spring 74 is locked to the stopper 66, and the other end is fixed to the bracket 32.
Is locked to. In this case, the biasing direction of the stopper 66 by the torsion coil spring 74 is always biased in the direction of arrow B in FIG. 5, unlike the first embodiment described above. The biasing force of the torsion coil spring 74 is set to be smaller than the biasing force of the plate spring 48 arranged between the cam 64 and the stopper 66.

Next, the operation of the second embodiment will be described. In the shift lever device 60 having the above-described configuration, the movement of the shift lever 12 is basically limited by the detent plate 20, similarly to the shift lever device 10 according to the first embodiment described above.

Further, when the shift lever 12 is selected in the "P" shift range, the guide pin 72 causes the stopper 6 to move.
When the grooved pin 14 is moved upward, the stopper 66 is rotationally moved upward by the urging force of the torsion coil spring 74 (the state shown in FIG. 5). ). As a result, the key interlock cable 58 is pushed in to operate the cable lock device, and movement of the key interlock cable 58, that is, rotation of the cam 64 and the stopper 66 is blocked.

Therefore, in this state, the grooved pin 14 is held by the guide portion 68 of the stopper 66, and the downward movement of the grooved pin 14 in the axial direction by the button operation is prevented. Further, since the guide pin 72 is located in the locking region 70B of the slit 70, the shift lever 12 is restrained by the slit 70 and the guide pin 72 and is prevented from moving. As a result, a shift lock state (so-called “P” range shift lock) in which movement of the shift lever 12 to a shift range other than the “P” shift range (movement in the “R” shift range direction) is blocked is provided. Become.

On the other hand, when the key and the brake are operated after the shift lever 12 has been selected in the shift range of "P" and in the shift lock state, the rotation preventing state of the cam 64 and the stopper 66 integral therewith is prevented. Is released and downward (Fig. 5
It is possible to rotate in the direction of arrow A). For this reason, the movement preventing state of the grooved pin 14 by the guide portion 68 of the stopper 66 is released, and the grooved pin 14 can be moved downward in the axial direction by operating the knob button. Therefore, when the grooved pin 14 is moved downward by operating the knob button, the guide portion 68 of the stopper 66 is pressed and the stopper 66 is rotated around the support shaft 30. further,
When the grooved pin 14 reaches the lowermost position, the guide pin 72 moves the locking region 70 of the slit 70 as shown in FIG.
The boundary portion (bent portion) between B and the guide region 70A is reached, and the guide region 70A is allowed to enter from the locking region 70B. As a result, the shift lever 12 enters a shift lock release state in which the shift lever 12 can be moved to a shift range other than the “P” shift range, and the shift lever 12 can perform a shift operation.

Further, the cam 64 and the stopper 66 are prevented from rotating downward (in the direction of arrow A in FIG. 5), and the guide pin 72 is positioned in the locking region 70B of the slit 70 to prevent the shift lever 12 from moving. In the shift lock state (the state shown in FIG. 5), when releasing the shift lock state without rotating the cam 64 connected to the ignition key portion (when manually forcibly releasing the shift lock), When the forced release button 42 provided on the vehicle body is operated, the arm portion 38 of the stopper 66 is pressed from above and elastically deformed, as shown in FIG.
Is released from the engagement of the locking projection 34 of the cam 64. Therefore, the stopper 66 can rotate independently of the cam 64. Therefore, by moving the grooved pin 14 downward in the axial direction, the stopper 66 is accordingly moved.
Only the cam 64 separates from the cam 64 and rotates downward (in the direction of arrow A in FIG. 7), and the guide pin 72 causes the engagement region 70 of the slit 70.
B reaches the boundary portion (bent portion) between the guide area 70A and the guide area 70A and enters the guide area 70A from the locking area 70B, and the shift lever 12 can be moved to a shift range other than the "P" shift range. The shift lock is released (the state shown in FIG. 7).

As described above, in the shift lever device 60 according to the second embodiment, the grooved pin 14 is pressed by the button operation.
Shift operation becomes possible by moving the shaft downward in the axial direction. Furthermore, in the "P" shift range, the cam 6
4 and the stopper 66 operate to enter a locked state or an unlocked state in which the shift lever 12 is prevented from moving. That is, the detent plate 20, the cam 64, and the stopper 6
With the mechanical and simple structure of 6, the shift lock state can be reliably achieved under specific conditions while ensuring further safety. Further, the shift lock state can be manually forcibly released.
