Description

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 selecting a shift position by operating a shift lever in a guide groove in the front, rear, left and right directions.

[0002]

2. Description of the Related Art In a shift lever device for a vehicle transmission,
The shift lever is guided by the guide groove of the guide plate to shift. Here, the guide groove is formed in a meandering manner, and the shift lever is moved forward, backward, leftward and rightward (so-called zigzag).
There is a configuration that is operated to select a shift position (for example, Japanese Utility Model Laid-Open No. 64-29024). In this type of shift lever device, when a shift operation is performed, the shift lever is guided to the front, rear, left and right by the unevenness of the guide groove and moved to a specific shift position.

By the way, in the shift lever device having such a structure, since the above-mentioned unevenness of the guide groove is formed continuously in the front, rear, left and right, the diameter of the shift lever (that is, the width dimension of the guide groove) is determined. If you do not make it relatively small,
The unevenness of the guide groove interferes with each other, and it becomes impossible to provide the unevenness of a required size. That is, if the unevenness of the guide groove is made too small, it causes a decrease in strength and is not preferable.

In this case, however, the diameter of the shift lever cannot be reduced in some cases due to design restrictions of the shift lever or restrictions on the overall size of the guide groove. Therefore, in such a case, one of the diameter of the shift lever and the dimension of the unevenness of the guide groove must be sacrificed to configure the shift lever device, and a countermeasure for this has been earnestly desired.

[0005]

SUMMARY OF THE INVENTION In consideration of the above facts, the present invention reliably moves the shift lever back and forth and left and right without restricting the degree of freedom of the radial size of the shift lever and the unevenness of the guide groove. It is an object of the present invention to obtain a shift lever device that can guide a vehicle to a specific shift position.

[0006]

A shift lever device according to the present invention is a shift lever device provided with a shift lever which is operated in the forward and backward and left and right directions in a guide groove of a guide plate to select a shift position. A detent pin that is interlocked with the lever and is movable relative to the shift lever when a predetermined load acts on the shift lever, and a groove corresponding to the shift position of the shift lever are continuously formed and A detent plate is provided with a detent pin that enters the detent pin and guides the detent pin to a specific shift position while limiting the movement of the detent pin by the groove, and is usually interlocked with the detent pin and is in a locked state at the specific shift position. Locking means for preventing the movement of the detent pin by It is a symptom.

[0007]

In the shift lever device having the above structure, when the shift lever is operated back and forth and left and right, the detent pin moves in conjunction with this. The detent pin is guided by the detent groove of the detent plate while limiting unnecessary movement, and moves to a specific shift position according to the operation of the shift lever.

As described above, the shift lever is moved to a specific shift position while being regulated by the detent pin and the detent groove, which are provided separately from the shift lever, to surely move the shift lever forward, backward, left and right. It can be moved and guided to a specific shift position.

Further, in the case where the width dimension of the guide groove of the guide plate is formed to be relatively large, the shift lever is operated in a direction different from the original shift operation direction, or the shift operation is blocked by the locking means. When the shift lever is forcibly operated and a predetermined load acts on the detent pin, the shift lever moves relative to the detent pin (in other words, the connection is released). Therefore, a large load does not act on the detent pin and the detent groove (detent plate), and the locking operation and the unlocking operation by the locking means are not hindered.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a shift lever device 10 according to the present invention.
The overall configuration of is shown in a front view. Further, FIG. 2 shows a plan view of the shift lever device 10.

In the shift lever device 10, the shift lever 12 is integrally projected upward from the upper end of the block 14. The lower end of the block 14 is rotatably attached to the shaft 18 by the pin 16, so that the shift lever 12 can rotate about the pin 16 (direction of arrow A in FIG. 1). The shaft 18 is rotatably attached to a bracket 20. Therefore, the shift lever 12 can rotate together with the shaft 18 around the axis of the shaft 18 (the depth direction in the plane of FIG. 1).

Further, the leaf spring 2 is provided in the middle of the block 14.
2 is locked. The leaf spring 22 extends in parallel with the shaft 18, and a roller 24 is attached to the tip of the leaf spring 22.

A link 26 is fixedly attached to the tip of the shaft 18, and the other end of the link 26 is connected to a cable of a rod which interlocks with a transmission (not shown).

The intermediate portion of the shaft 18 (block 1
A block 30 is rotatably attached by a pin 28 between 4 and the link 26. In this case, the mounting position of the pin 28 is set so that the block 30 rotates and moves on the same plane as the block 14. The block 30 also rotates together with the shaft 18 around its axis.

A recess 32 is formed in the middle of the block 30, and the roller 24 of the leaf spring 22 described above is inserted therein. Therefore, normally, the block 14 and the block 30 are connected by the leaf spring 22 and the block 30 is interlocked with the block 14, and when a large relative load is applied between the block 14 and the block 30, the leaf spring 22 elastically deforms. The roller 24 comes out of the recess 32, and the block 14 and the block 30 are disconnected.

A detent pin 34 is integrally fixed to the upper end of the block 30 in an upward direction.

The shift lever 12 and the detent pin 34 having the above-described structure are provided with a guide groove 3 formed in a plate 36 serving as a guide plate and a detent plate.
No. 8, they are in the detent groove 40, respectively.

As shown in detail in FIG. 2, the guide groove 38 is formed in a meandering shape (continuously unevenness is formed), and the shift lever 12 can be shifted forward and backward and left and right (so-called zigzag). .. In this case, the width dimension of the guide groove 38 is formed relatively wider than the diameter of the shift lever 12, and the shift lever 12 can move with a margin.

On the other hand, the detent groove 40 has a shift position of the shift lever 12, that is, "P", "R", "N",
The inner peripheral wall is continuously bent in an uneven shape in association with each shift position of “D”, “3”, “2”, and “L”, and this unevenness restricts the movement of the detent pin 34. While guiding to a specific shift position. In this case, the width dimension of the detent groove 40 is formed to be substantially the same as the diameter of the detent pin 34, and therefore the detent pin 3 is formed.
No. 4 is configured so that it cannot move in the left-right direction and in the front-rear direction at the same time.

A locking device 42 as a locking means is arranged near the intermediate portion of the detent pin 34.

The lock device 42 includes a slide piece 44 and a slide piece 46. As shown in detail in FIGS. 3 to 5, the slide piece 44 and the slide piece 46 are both rectangular plate members and are slidably arranged in a state of being vertically stacked. The sliding direction of the slide piece 44 and the slide piece 46 is along the moving direction of the detent pin 34 due to the rotation of the shaft 18.

A long hole 48 is formed in the central portion of the slide piece 44 located on the upper side, and the detent pin 34 is formed.
The middle part of the has entered. The elongated hole 48 is formed so as to be inclined at an angle of about 45 degrees with respect to the longitudinal axis (moving direction) of the slide piece 44, and its width dimension is formed to be substantially the same as the diameter of the detent pin 34. There is. on the other hand,
The long hole 5 is provided at the center of the slide piece 46 located on the lower side.
0 is formed, and similarly, the intermediate portion of the detent pin 34 is inserted. The elongated hole 50 is formed so as to be inclined with respect to the longitudinal axis (moving direction) of the slide piece 46 at an angle of approximately 45 degrees which is the opposite direction of the elongated hole 48 (therefore, the elongated hole 48 and the elongated hole 50). And the width dimension thereof is approximately the same as the diameter of the detent pin 34.

Therefore, when the detent pin 34 rotates around the axis of the shaft 18, the slide piece 44 and the slide piece 46 slide together with the detent pin 34. On the other hand, when the detent pin 34 is rotationally moved around the pin 28, the detent pin 34 presses the inner walls of the elongated holes 48 and 50 so that the slide piece 44 and the slide piece 46 relatively move in opposite directions. Is.

Slide piece 44 and slide piece 4
A notch 52 and a notch 54 are formed in the vicinity of the longitudinal end portion of each of the widthwise one end portions of 6, respectively. The notch 52 and the notch 54 are set so as to overlap each other when the shift lever 12, that is, the detent pin 34 interlocked with the shift lever 12 is located at the "P" shift position.

A notch 70 is formed at the side of the notch 52 of the slide piece 44, and a notch 72 is formed at the end of the slide piece 46 opposite to the notch 54. The notch 72 is formed so that the width dimension (the dimension along the slide movement direction of the slide piece 46) is relatively long, and when the detent pin 34 is located at the “N” shift position, the notch 72 is notched. The notch 54 side end and the notch 70 are set to overlap.

On the other hand, a cutout 74 is formed at the end of the slide piece 44 opposite to the cutout 52 (that is, on the side of the cutout 70). The notch 74 includes the notch 70.
An inclined surface 76 is formed at the end portion on the side. This notch 7
No. 4 is set so as to overlap the end of the cutout 72 when the detent pin 34 is located at the shift position of "2".

Slide piece 44 and slide piece 4
In the vicinity of 6, an L-shaped lock arm 56 is rotatably attached by a pin 58. Lock arm 5
One end of 6 can be fitted into the cutouts formed in the slide piece 44 and the slide piece 46 (for example, the cutout 52 and the cutout 54) when they overlap with each other, and thus the slide piece 44 in this state. Also, the sliding movement of the slide piece 46 is prevented. That is, the shift lock state is set.

A plunger 62 of a solenoid 60 is connected to the other end of the lock arm 56. The solenoid 60 attracts the plunger 62 when energized, and the solenoid 62 is pulled out by the urging force of the return spring provided inside when the solenoid 60 is not energized. When the solenoid 60 is excited, the lock arm 56 is rotated around the pin 58 in the direction of arrow B in FIG. 1 by pulling in the plunger 62 against the biasing force of the return spring. When the lock arm 56 is rotated in the direction of the arrow B as described above, the lock arm 5 moves from the overlapping notches (for example, the notches 52 and 54).
The tip end portions of 6 are separated from each other.

This solenoid 60 is used for the shift lever 12
Energization and deenergization are performed by electrical control according to the shift position and the running state of the vehicle.

Next, the operation of this embodiment will be described. In the shift lever device 10 having the above configuration, when the shift lever 12 is operated in the guide groove 38 in the front-rear direction and the left-right direction, the operation force in the front-rear direction is transmitted to the detent pin 34 via the shaft 18, and the left-right operation is performed. The force is transmitted to the detent pin 34 via the leaf spring 22, which causes the detent pin 34 to move in conjunction with the shift lever 12.

The detent pin 34 is guided by the unevenness of the detent groove 40 of the plate 36, and the shift lever 1
Move to a specific shift position according to the operation of 2 with a feeling of moderation. In this way, the shift lever 12 is moved to a specific shift position while being regulated by the detent pin 34 and the detent groove 40 that are provided separately from the shift lever 12, and the shift lever 12 is securely moved. It can be moved back and forth and left and right to guide to a specific shift position.

The detent pin 34 and the detent groove 40 are used to guide the shift lever 12 to a specific shift position.
Even if the width dimension of the guide groove 38 is formed to be relatively large (even if its contour or shape is inaccurate), the shift lever 12 rattles or shifts unnecessarily. There is no loss of moderation when moving. Therefore, the diameter of the shift lever 12 can be increased, and the diameter of the shift lever 12 and the guide groove 3 can be increased.
The degree of freedom in dimension setting is improved without restricting the uneven dimension of No. 8.

Here, for example, when the shift lever 12 is selected to the "P" shift position, the slide piece 4
The notch 52 of No. 4 overlaps with the notch 54 of the slide piece 46. Along with this, the energization of the solenoid 60 is released, and the tip end portion of the lock arm 56 enters into the notches 52 and 54 of the slide pieces 44 and 46 (the state shown in FIG. 3). Therefore, the slide piece 44,
The sliding movement of 46 is blocked. Therefore, the detent pin 34 is also prevented from moving and enters the shift lock state, and the shift lever 12 is prevented from shifting.

When the shift lever 12 is forcibly operated in such a state, this operating force is transmitted to the detent pin 34 via the leaf spring 22. Therefore, the notch 52,
54 is engaged with the tip of the lock arm 56 with a large pressing force. However, when such a load transmitted from the shift lever 12 to the detent pin 34 exceeds a predetermined value, the leaf spring 22 elastically deforms and the roller 24 slips out of the recess 32, and the shift lever 12 and the detent pin 34 are connected. Is released, the shift lever 12 can move relative to the detent pin 34 in the direction of arrow A in FIG.

Therefore, a large load does not act on the detent pin 34 and the detent groove 40. further,
The notches 52, 54 of the slide pieces 44, 46 do not engage with the tip of the lock arm 56 with a large pressing force, and the lock arm 56 is in a state where it can be easily pulled out from the notches 52, 54.

When such a large load transmission exceeding the predetermined value transmitted from the shift lever 12 to the detent pin 34 is canceled, the elastic force of the leaf spring 22 causes the roller 24 to enter the recess 32, and the shift lever 12 Becomes the normal connection state with the detent pin 34 again.

On the other hand, when the ignition switch of the vehicle is turned on and the brake is depressed after the shift lever 12 has been selected to the "P" shift position and is in the shift lock state, the solenoid 60 is energized again. As a result, the tip of the lock arm 56 is moved to the slide piece 4
When the slide pieces 44 and 46 are slidable, the slide pieces 44 and 46 are disengaged from the notches 52 and 54. Therefore, the detent pin 34 can also be moved, the shift lock is released, and the shift lever 12 can perform the shift operation.

When the shift lock is released, the notch 5 of the slide pieces 44 and 46 as described above.
The lock arms 56 can easily be pulled out from the notches 52 and 54, because the lock arms 56 and 2 do not engage with the tip of the lock arm 56 with a large pressing force, and the lock release operation of the lock arm 56 is hindered. Never.

On the other hand, when the shift lever 12 is selected to the "N" shift position, the notch 70 of the slide piece 44 is formed.
Is in a state of overlapping with the end of the notch 72 of the slide piece 46. In this case, if the vehicle is traveling, the solenoid 60 continues to be energized, and the lock arm 5
The tip of 6 does not enter the notches 70 and 72.
Therefore, the shift lock state does not occur. When the vehicle stops, the energization of the solenoid 60 is released accordingly, and the tip end of the lock arm 56 is cut out.
0, 72 (state shown in FIG. 4). Therefore, the sliding movement of the slide pieces 44 and 46 is prevented as in the above. Therefore, the detent pin 34 is also prevented from moving and enters the shift lock state, and the shift lever 12 is prevented from shifting.

Even in this state, when a large load is transmitted from the shift lever 12 to the detent pin 34, the connection between the shift lever 12 and the detent pin 34 by the leaf spring 22 is released, and the shift lever 12 is detented. The pin 34 and the detent pin 34 and the detent groove 40 can be moved relatively to each other in the direction of arrow A in FIG. Furthermore, slide piece 4
The notches 70 and 72 of Nos. 4 and 46 do not engage with the tip end portion of the lock arm 56 with a large pressing force, and the lock arm 56 can be easily pulled out from the notches 70 and 72.

When the brake is depressed after the shift lock state is established, the solenoid 60 is energized again. As a result, the tip end portion of the lock arm 56 is disengaged from the notches 70 and 72 of the slide pieces 44 and 46, and the slide pieces 44 and 46 can be slid. Therefore, the detent pin 34 can be moved and the shift lock is released, and the shift lever 12
Can perform shift operations.

Even when the shift lock is released, the cutouts 7 of the slide pieces 44 and 46 are as described above.
Since 0 and 72 do not engage with the tip of the lock arm 56 with a large pressing force, the lock arm 56 can be easily slipped out of the notches 70 and 72, and the unlocking operation of the lock arm 56 is hindered. Never.

On the other hand, when the shift lever 12 is selected to the "2" shift position, the notch 74 of the slide piece 44 overlaps with the end of the notch 72 of the slide piece 46.

In this case, if the vehicle is running at a high speed, the solenoid 60 is de-energized and the lock arm 5 is released.
The tip of 6 enters into the notches 72 and 74 (state shown in FIG. 5). Therefore, the sliding movement of the slide pieces 44, 46 downward in FIG. 5, that is, the movement of the detent pin 34 from the “2” position in the “L” direction is blocked, and the shift lock state is established, which prevents the engine from over-rotating. To be done.

On the other hand, in this state, since the notch 72 of the slide piece 46 is formed long in the width direction, the slide piece 46 can be slid upward in FIG. Further, since the slide piece 44 also has the inclined surface 76 formed in the notch 74, the inclined surface 76 moves while pressing the tip end portion of the lock arm 56, whereby the slide piece 44 slides upward in FIG. Is possible. Therefore, the detent pin 34 “2”
It is possible to move from the position in the "3" direction.

Even when the shift lever 12 is selected to the "2" shift position, when a large load is transmitted from the shift lever 12 to the detent pin 34, the leaf spring 22 causes the shift lever 12 and the detent pin 34 to move.
Since the connection with the shift lever 12 is released, the shift lever 12 can move relative to the detent pin 34 in the direction of arrow A in FIG. 1, and a large load does not act on the detent pin 34 and the detent groove 40. Further, when the vehicle is traveling at a low speed, the solenoid 60 is energized again, and the lock arm 56
The distal end of the is separated from the notches 72 and 74, and the shift lock is released. Also in this case, the slide piece 44,
Since the notches 72 and 74 of 46 do not engage with the tip end portion of the lock arm 56 with a large pressing force, the lock arm 56 can easily be pulled out from the notches 72 and 74.

Thus, in the shift lever device 10,
The shift lever 12 is moved to a specific shift position while being regulated by a detent pin 34 and a detent groove 40, which are provided separately from the shift lever 12, so that the shift lever 12 can be reliably moved forward, backward, leftward and rightward. And can guide to a specific shift position. The detent pin 3 is used to guide the shift lever 12 to a specific shift position.
4 and the detent groove 40, the shift lever 12 is not necessary even if the guide hole 38 is formed to have a relatively large width (the contour or the shape is incorrect). It does not rattle or lose the sense of moderation when shifting. Therefore, the diameter of the shift lever 12 can be increased, and the diameter of the shift lever 12 and the unevenness of the guide groove 38 are not restricted, and the degree of freedom in dimension setting is improved.

Further, in the shift lever device 10, the shift locks at the shift positions of "P", "N", and "2" of the shift lever 12 are locked by the slide pieces 44, 4, 4.
Since a simple configuration using 6 is used, the mechanism is simple and a small arrangement space is required, and a significant cost reduction can be achieved.

Further, in the shift lever device 10, since the shift lever 12 and the detent pin 34 are connected by the leaf spring 22, a large load does not act on the detent pin 34 and the detent groove 40. Further, since the respective cutouts of the slide pieces 44 and 46 do not engage with the tip end portion of the lock arm 56 with a large pressing force, the lock arm 56 can be easily pulled out from the cutouts 52 and 54, and the lock arm 56 can be easily removed. The unlocking operation of 56 is not hindered.

In this embodiment, the plate 36
Is used both as a guide plate and a detent plate, and a guide groove 38 and a detent groove 4 are provided in this plate 36.
However, the present invention is not limited to this, but the guide groove 38 and the detent groove 40 are formed on independent plates. Good. In this case, the degree of freedom in the arrangement position of the detent groove 40 (detent plate) is further improved, and it is possible to install the detent groove 40, for example, at an internal position of the device which is not visible to an occupant.

[0051]

Since the present invention has the above-described structure, the shift lever can be reliably moved forward, backward, leftward and rightward to guide to a specific shift position, and the shift lever can be guided to a specific shift position by a detent pin and a detent groove. Since it is carried out while being regulated by and, even if the width of the guide groove of the guide plate is made relatively large, the shift lever does not unnecessarily rattle or lose the feeling of moderation during shift movement. The diameter of the shift lever can be increased, and the dimension of the shift lever and the size of the guide groove are not restricted, and the degree of freedom in dimension setting is improved.
It has an excellent effect.
