Abstract

PROBLEM TO BE SOLVED: To provide a shift-lock mechanism for a shift lever device permitting its compact whole size. SOLUTION: A stopper 64 with its engaging part 78 being fitted into a case 102 of a solenoid 100 is attached on a strengthening gate 60. When a shift lever 12 is shifted from the N or P range to the R range, it contacts with the stopper 64. In this state, if the solenoid 100 is in its nonconducting state, the stopper 64 is held by a lock member within the case 102 against its movement to thereby block the movement of the shift lever 12 to the R range. On the other hand, the solenoid 100 in its conducting state permits the movement of the lock member, and the stopper 64 moved by the operation of the shift lever 12 presses the lock member to move it to thereby allow the movement of the shift lever 12 to the R range.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift lock mechanism for a shift lever device used in a shift lever device for shifting a transmission, which prevents the shift lever from moving at a specific shift position.

[0002]

2. Description of the Related Art A shift lever device for operating a shift lever provided in a vehicle compartment to change an automatic transmission of a vehicle to a desired shift range includes, for example, a shift lever not only in the longitudinal direction of the vehicle but also in the vehicle. There is a so-called gate type (zigzag operation) type shift lever device that selects an arbitrary shift range by also operating in the width (left / right) direction.

In this type of gate-type shift lever device, for example, the shift lever is moved in a vehicle width direction from a state in which the shift lever is selected to a neutral range (hereinafter, referred to as an "N range"). There is a type in which the shift range can be changed to a reverse range (hereinafter, referred to as "R range") by a two-stage shift lever operation of moving the lever forward of the vehicle.
However, in such a shift lever device, the shift lever may move from the N range to the R range by one operation of merely applying a pressing force diagonally forward to the shift lever. There is a need for a shift lock mechanism that allows the shift lever to move from the N range to the R range.

In this type of shift lock mechanism, for example,
There is known a configuration in which a stopper for preventing the shift lever from moving from the P range to the R range and from the N range to the R range is connected to a solenoid plunger via a link mechanism including an arm and a rod. . In such a shift lock mechanism, the plunger is urged in a predetermined direction by an urging force of a coil spring or the like, and the stopper is located at a position for preventing movement of the shift lever in a normal state by this urging force. When the brake pedal is depressed by the vehicle occupant or when the speed of the running vehicle is lower than a predetermined speed, the solenoid is energized, and the plunger is attracted and moved by the magnetic force against the aforementioned urging force. Further, the operation of the plunger is transmitted to the stopper via the link mechanism, and the stopper retreats from the position where the shift lever is prevented from moving. Thus, the shift lever can be moved from the P range to the R range or from the N range to the R range.

[0005]

By the way, in such a shift lock mechanism, when the stopper is retracted from the position where the shift lever is prevented from moving, an attraction force (magnetic force) greater than the above-described urging force is required. However, power consumption for generating the attraction force is large, and a large solenoid is required. For this reason, there has been a problem that the size of the shift lock mechanism is increased as a whole.

An object of the present invention is to provide a shift lock mechanism of a shift lever device capable of reducing the size of the entire mechanism in consideration of the above fact.

[0007]

According to a first aspect of the present invention, there is provided a shift lock mechanism of a shift lever device, wherein a shift lever connected to a transmission of a vehicle is operated in a non-linear manner in a predetermined direction. A shift lock mechanism for a shift lever device applied to a shift lever device capable of changing a shift range, wherein the shift lever device prevents movement of the shift lever to a specific shift range when the shift lever is located in a predetermined shift range. A stopper which is installed at a lock position where movement of the shift lever to the specific shift range can be prevented, and which comes into contact with the shift lever and can be released from the lock position by a pressing force from the shift lever; A locking member that is constantly urged toward the disengagement movement trajectory of the stopper that disengages from the position, and is in a non-energized state A lock means for preventing the lock member from moving away from the stopper on the disengagement movement trajectory, and for retracting the lock member from the disengagement movement trajectory by a pressing force from the stopper disengaging from the lock position in an energized state. And characterized in that:

In the shift lock mechanism of the shift lever device having the above structure, when the shift lever is moved from the predetermined shift range to the specific shift range, the shift lever is moved to the stopper before the shift lever moves to the specific shift range. And press the stopper.

If the locking means is not energized and the stopper is to be released from the locked position by the pressing force from the shift lever, the releasing movement of the stopper is prevented by the locking member on the releasing movement locus. . For this reason, the stopper cannot be disengaged from the locked position even if it receives the pressing force from the shift lever, and the movement of the shift lever to a specific shift range is prevented by the stopper.

On the other hand, when the locking means is in the energized state, when the stopper pressed by the shift lever attempts to separate from the locked position and the stopper presses the locking member, the pressing force causes the locking member to move away. Retreat from the track. Thus, the stopper moves from the lock position by the pressing force from the shift lever, and the shift lever can move from a predetermined shift range to a specific shift range.

Here, in the present shift lock mechanism, the stopper moves by the pressing force from the shift lever.
Since the lock member is moved by the pressing force from the stopper, there is no need to move the lock member or the stopper by the suction force of the solenoid as in the conventional shift lock mechanism, and if the lock member becomes movable when the locking means is energized. Good. Therefore, the lock means of the present shift lock mechanism does not require a large amount of electric power unlike a solenoid applied to a conventional shift lock mechanism. Therefore, the size of the lock means can be reduced as compared with the conventional solenoid, and the size of the entire shift lock mechanism can be reduced.

According to a second aspect of the present invention, there is provided the shift lock mechanism of the shift lever device according to the first aspect, wherein the locking means is provided between the lock member and the stopper on the disengagement movement trajectory. A driven member that retreats in the same direction as the retraction direction of the lock member from the departure movement trajectory by a pressing force from the departure stopper that is interposed therebetween, and is integrated with the lock member; Fixing means for preventing relative movement of the driven member with respect to the lock member and retracting the lock member together with the driven member.

In the shift lock mechanism of the shift lever device having the above structure, a driven member is interposed between the lock member on the movement locus of the stopper and the stopper, and the stopper receives the pressing force from the shift lever to move the stopper to the lock position. When the driven member is separated, the driven member is pressed by the stopper and retreats from the movement locus of the stopper.

Here, when the lock means is in the non-energized state, the driven member and the lock member are in a state in which the driven member and the lock member can move relative to each other, so that the driven member is moved by the pressing force from the stopper pressed by the shift lever. The lock member also prevents the stopper from moving on the movement path. For this reason, the stopper cannot be disengaged from the locked position even if it receives the pressing force from the shift lever, and the movement of the shift lever to a specific shift range is prevented by the stopper.

On the other hand, when the locking means is energized, the relative movement of the driven member with respect to the locking member is prevented, so that the driven member receives the pressing force from the stopper pressed by the shift lever. When the lock member moves, the lock member moves integrally with the driven member, and retreats from the movement locus of the stopper together with the driven member. Thus, the stopper moves from the lock position by the pressing force from the shift lever, and the shift lever can move from a predetermined shift range to a specific shift range.

Here, the power required for energizing the locking means only needs to be able to prevent the relative movement of the driven member with respect to the locking member, and is compared with the power consumption used for sucking and moving the plunger like a conventional solenoid. Power consumption is reduced. For this reason, the locking means can be reduced in size as compared with the conventional solenoid, and the overall shift lock mechanism can be reduced in size.

That is, the shift range of the automatic transmission can be changed to the shift range corresponding to the character 38 by moving the shift lever 12 in a zigzag manner inside the shift groove 40.

On the other hand, a lower housing 42 is disposed below the upper housing 36. Lower housing 4
Reference numeral 2 denotes a box formed of a resin material such as ABS resin similarly to the upper housing 36, and a rectangular opening 44 having a longitudinal direction extending in the vehicle front-rear direction is formed in the ceiling 42A. The opening 44 is provided in the upper housing 36.

Through holes 54 and 56 through which the shift lever 12 penetrates are formed in these cover slides 50 and 52. When the shift lever 12 moves in the shift groove 40, the cover slides 50 and 52 are pressed by the shift lever 12 and the vertical wall portions 46 and 48 are formed. Move up. In addition, these cover slides 50 and 52
Even when the shift lever 12 moves within the shift groove 40 and is located in any shift range, the shift groove 40 can be shielded, thereby preventing foreign matter from entering from above the upper housing 36.

On the other hand, below the lower housing 42, a plate-like strength gate 60 is arranged. Here, FIG. 2 is an enlarged perspective view of the strength gate 60, and FIGS. 3 to 7 are plan views of the strength gate 60. 3 to 7 show the locus of the shift lever 12 when changing the shift range. As shown in these figures, the intensity gate 60
Is formed with a gate groove 62. This gate groove 62
Is formed in a zigzag shape bent in the front-rear direction and the width direction of the vehicle similarly to the shift groove 40 of the upper housing 36 described above, and the shift lever 12 penetrates. Here, the width dimension of the shift groove 40 is larger than the diameter dimension of the shift lever 12, whereas the width dimension of the gate groove 62 is slightly larger than the diameter dimension of the shift lever 12. I have. For this reason, the shift lever 12 is prevented from moving in the width direction of the gate groove 62, and when the shift lever 12 is operated, the shift lever 12 is always guided by the gate groove 62 and moves, so that the shift lever 12 moves to a predetermined position in the gate groove 62. When the shift lever 12 is reached, the shift range of the automatic transmission is changed.

Furthermore, a stopper 64 is placed on the left side of the gate trench 62 on the strength gate 60 (direction of arrow X _2). The stopper 64 has a connecting portion 66, and an N stopper portion 68 is formed at the rear end of the connecting portion 66. The N stopper portion 68 corresponds to the shift lever 12 in a state where the shift lever 12 is located in the N range (that is, the state illustrated in FIG. 3), and the stopper 64 is located in the lock position on the gate groove 62 (the solid line in FIG. 2). In the (state), the N stopper portion 68 prevents the shift lever 12 from moving from the N range to the R range (that is, from the range).

On the other hand, a P stopper 74 is formed at the front end of the connecting portion 66. This P stopper portion 74
Is in the P range (ie, the state shown in FIG. 6)
In the state where the stopper 64 is located at the lock position on the gate groove 62, the P stopper 74 moves from the P range to the R range (that is,
The shift lever 12 is prevented from moving. Further, from the front end of the P stopper 74, a narrow rectangular bar-shaped engaging portion 78 extends toward the side opposite to the gate groove 62.

On the other hand, it is formed projecting toward the side opposite to the gate trench 62 is a pair of protrusions 80, 82 on the side surface of the opposite side (direction of arrow X ₂₎ of the gate groove 62 of the stopper 64. On the other hand, on the strength gate 60, support portions 84 and 86 having a rectangular block shape are provided. These support parts 8
4, 86 are provided corresponding to the projections 80, 82,
Circular holes 88, 90 which is open towards the gate groove 62 side (the arrow X ₁ direction) are formed. Inside these circular holes 88, 90 and projections 80, 82 are inserted, thereby, the movement of the stopper 64 is restricted only in the vehicle width direction (the arrow X _1, X ₂ direction). A coil spring 92 is inserted through the projection 80, and the coil spring 92 is inserted into the circular hole 88 with the coil spring 92 inserted. One end of the coil spring 92 is in contact with the bottom of the circular hole 88 of the support portion 84, and the other end is in contact with the side surface of the stopper 64 on the side opposite to the gate groove 62. urges toward (the direction of arrow X _1). Therefore, a force in a direction opposite to the urging force of the coil spring 92 and greater than the urging force is applied to the stopper 6.
If it does not act on 4, the stopper 64 is located at the lock position (solid line in FIG. 2).

Further, the pin 94 is erected in front of the gate groove 62 of strength gate 60 (arrow Y ₁ direction).
The pin 94 corresponds to the P stopper 74 of the stopper 64, and contacts the P stopper 74 of the stopper 64 in a state where the stopper 64 is located at the lock position. As a result, further movement of the stopper 64 toward the gate groove 62 is prevented.

Further, a solenoid 100 as a locking means is attached to the left front end of the strength gate 60. The solenoid 100 has a rectangular box-shaped case 102, and a rectangular guide hole 104 is formed on the right side wall of the case 102. The guide hole 104 corresponds to the engaging portion 78 of the stopper 64 described above, and the engaging portion 78 penetrates the guide hole 104 from outside the case 102 and enters the inside of the case 102. In front of the guide hole 104, a rectangular guide hole 106 is also provided.
Is formed, and a rectangular bar-shaped forcible release lever 108 penetrates the guide hole 106 from the outside of the case 102 and enters the inside of the case 102.

As shown in the plan sectional view of FIG. 8, a lock member 110 is housed inside the case 102. The lock member 110 has a rectangular block-shaped lock portion 112. This lock section 112
There vehicle rear side of the case 102 (i.e., the arrow Y ₂ direction side) in contact with the side wall 102A of the lock portion 11
2 is located on the left side of the guide hole 104 in the vehicle width direction and faces the engaging portion 78 of the stopper 64.
4) The movement of a predetermined stroke or more inside the case 102 is prevented. In addition, the lock member 110 is
2 is adapted to be slid towards the front of the vehicle (arrow Y ₁ direction) along the side wall 102B of the left side in the vehicle width direction of the case 102 from contact with the side wall 102A (arrow X ₂ direction side). Further, a connecting portion 114 is formed on the lock member 110. The connection part 114 is the lock part 1
It is extended in a state of being bent in a hook shape from a side of the vehicle front side of the 12 (arrow Y ₁ direction side) toward the front of the vehicle. Electromagnet 116 as a fixing means is integrally fixed to the case 102 inside of the connecting portion 114 (the arrow X ₁ direction). Electromagnet 116 is the vehicle rear direction (the arrow Y ₂ direction side) to toward the opened bottom of the cylindrical coil 118 are fragments winding to the outside.

The coil 118 is wound so that when energized, a magnetic force is generated from the inside to the outside of the electromagnet 116 in the vehicle width direction. The coil 118 is connected to a shift lock computer (not shown). The shift lock computer is used to determine the vehicle status and shift lever 1
2 are connected to a plurality of sensors (not shown) for detecting the position of the vehicle 2. For example, when the vehicle occupant depresses the brake pedal when the vehicle is stopped, or when the vehicle occupant depresses the brake pedal while the vehicle is running, the vehicle When each sensor detects a state where the speed has been reduced to a speed equal to or lower than the speed, the shift lock computer turns on the coil 118.

Further, the vehicle having the electromagnet 116 and the case 102
Between the front side wall 102C and the coil spring 12
0, and the electromagnet 116 is always held at the rear of the vehicle (arrow
Mark Y _TwoDirection). For this reason, electromagnets
The lock portion 112 of the lock member 110 integrated with the
It is always in contact with the side wall 102A.

On the other hand, a cam plate 124 is disposed behind the electromagnet 116 in the vehicle. The right end of the cam plate 124 in the vehicle width direction is folded back toward the rear of the vehicle, and further inclined toward the rear end toward the left side in the vehicle width direction. The cam portion 126 corresponds to the guide hole 106, and when the forcible release lever 108 moves to the inside of the case 102 by the operation force of the vehicle occupant, the cam portion 126 is pressed by the forcibly released lever 108 and the coil 118 is energized. Regardless of the state or the non-energized state, the electromagnet 116 moves forward against the urging force of the coil spring 120, and the lock member 110 moves forward (the state shown in FIG. 11).

A main body 128A of the plunger 128 is disposed inside the electromagnet 116 so as to be slidable in the front-rear direction of the vehicle. Here, the plunger 128 is formed of a metal material, and when a current flows through the coil 118, the inner wall of the electromagnet 116 is magnetized. As a result, the main body 128A is attracted to the inner wall of the electromagnet 116. Also,
This body 128A has a hole 12 opened toward the front of the vehicle.
8B are formed, and a coil spring 130 is accommodated in the hole 128B. One end of the coil spring 130 contacts the bottom of the hole 128B and the other end contacts the bottom of the electromagnet 116, and biases the main body 128A toward the rear of the vehicle with respect to the electromagnet 116.
Here, the biasing force of the coil spring 130 is set to be smaller than the biasing force of the coil spring 120, and the plunger 128 (the main body 128A) of the electromagnet 116 in a state where the biasing force of the coil spring 120 is excited. ) Is set to be greater than the urging force of the coil spring 120.

On the other hand, a protruding portion 128C whose outer diameter is smaller than that of the main body 128A is formed at the vehicle rear end side end of the main body 128A of the plunger 128. Projecting to A cam member 132 as a driven member is attached to the tip of the projection 128C. The cam member 132 has a trapezoidal cross section, and an end 132A on the vehicle rear side is an inclined surface inclined to the left side of the vehicle. Also, this cam member 1
Reference numeral 32 denotes a lock member in a state where the lock portion 112 abuts against the side wall 102A of the case 102 by the urging force of the coil spring 130 and the main body 128A of the plunger 128 abuts on the cam plate 124 by the urging force of the coil spring 120. Lock portion 112 of 110 and stopper 6
4 between the engaging portions 78 of the cam member 132.
32 </ b> A faces the engaging portion 78 of the stopper 64. Therefore, when the engaging portion 78 of the stopper 64 is moved to the inside of the case 102, an end portion 132A of the cam member 132 is pressed by the engaging portion 78, moves toward the front of the vehicle (arrow Y ₁ direction).

Next, the operation of the present embodiment will be described. If the present shift lever device 10 moves the shift lever 12 is shifted to the N range (Figure 3 illustrated state) R-range, first pushes the shift lever 12 to the leftward (direction of arrow X _2). Shift lever 12 pressed
Moves toward the position guided by the gate groove 62,
The N stopper 68 of the stopper 64 is pressed to the left. This pressing force causes the engagement portion 78 to move the solenoid 100
Further into the case 102. First, the engaging portion 78 that has entered the inside of the case 102
132A is pressed to the left. Since the end 132A of the cam member 132 has an inclined surface inclined to the left side of the vehicle, the pressing force from the engaging portion 78 (stopper 64) is divided into a leftward component and a forward component.

Here, when the coil 118 of the electromagnet 116 is not energized, the main body 128A of the plunger 128 is turned off.
Is not attracted to the electromagnet 116, the plunger 128
128A is slidable inside the electromagnet 116, and when the cam member 132 receives a pressing force from the engaging portion 78 (stopper 64), the main body of the plunger 128 is opposed to the urging force of the coil spring 130. Slide forward. In this state, the main body 1 of the plunger 128
28A is connected to the electromagnet 116 via the coil spring 130.
Is pressed toward the front of the vehicle, but since the urging force of the coil spring 130 is smaller than the urging force of the coil spring 120, even if the main body 128A of the plunger 128 slides forward of the vehicle, the coil spring 120 only contracts. Therefore, the electromagnet 116 does not move. Therefore, the electromagnet 1
Lock portion 112 of lock member 110 which is integral with 16
Is located at a predetermined position on the left side of the guide hole 104 in the vehicle width direction, engages with the engaging portion 78 of the stopper 64, and prevents the engaging portion 78 from moving inside the case 102 (the state shown in FIG. 9). . In this state, the shift lever 12 is
Cannot be moved to a position in the gate groove 62 even if the N stopper 68 is pressed, and therefore cannot be moved to a position corresponding to the R range through the position. Therefore, the shift of the shift lever 12 from the N range to the R range is reliably prevented.

On the other hand, for example, when the vehicle detects that the vehicle occupant depresses the brake pedal and the vehicle is decelerated to a predetermined speed or less, the sensor detects that the coil 118 is energized by the shift lock computer. The main body 128A of the plunger 128 is
6, the main body 128A of the plunger 128
And the electromagnet 116 are integrated. Here, since the resultant force of the urging force of the coil spring 130 and the attraction force of the electromagnet 116 is larger than the urging force of the coil spring 120, the plunger is pressed by the pressing force received by the cam member 132 from the engaging portion 78 (stopper 64). The electromagnet 116 integrated with the main body 128 </ b> A of the 128 moves forward of the vehicle against the urging force of the coil spring 120. Here, the electromagnet 116
It suffices if the plunger 128 can be adsorbed with an adsorbing force such that the resultant force with the urging force of the coil spring 130 is larger than the urging force of the coil spring 120. Therefore, unlike the conventional shift lock mechanism, it is not necessary for the attraction force (magnetic force) of the electromagnet 116 to attract and move the lock member 110 against the urging force of the coil spring 120. Therefore, the current flowing through the coil 118 can be reduced, and the size of the electromagnet 116 can be reduced.

As a result, the lock member 110 integrated with the electromagnet 116 moves to the front of the vehicle, and the lock portion 112 retreats from the predetermined position on the left side of the guide hole 104 in the vehicle width direction to the front of the vehicle. Therefore, the engaging portion 78 of the stopper 64 further enters the inside of the case 102 by the pressing force from the shift lever 12 (the state shown in FIG. 10). In this state, the stopper 64 moves from the lock position against the urging force of the coil spring 92 by the pressing force of the shift lever 12, so that the shift lever 12 can move to the position (the state shown in FIG. 4). Further, when moving the shift lever 12 to a position forward (arrow Y ₁ direction) operation to gated groove 62 from this state, the shift range of the shift lever 12 is changed to the R range.

When the shift lever 12 has moved to the R range, the stopper 64 released from the pressing force of the shift lever 12 returns to the locked position again by the urging force of the coil spring 92. When the stopper 64 returns to the locked position, the engaging portion 78 of the stopper 64 moves outward of the case 102 and
The cam member 132 and the lock member 110 are moved toward the rear of the vehicle by the urging force of the coil spring 120, and each of them is moved to a predetermined position on the left side of the guide hole 104 in the vehicle width direction. It returns to the position (the state shown in FIG. 8).

On the other hand, in the case of moving the shift lever 12 is shifted to the P range (Figure 6 illustrated status) R-range, first pushes the shift lever 12 to the leftward (direction of arrow X _2). The pressed shift lever 12 is moved to the gate groove 62.
To the position, and the stopper 64
The stopper 74 is pressed to the left. As a result, the engaging portion 78 of the stopper 64 further enters the case 102 of the solenoid 100, and the engaging portion 78
32 is pressed against the end 132A.

Here, similarly to the case where the shift lever 12 is moved from the N range to the R range, the electromagnet 1
When the sixteen coils 118 are not energized, the lock member 11
The lock portion 112 is located at a predetermined position on the left side of the guide hole 104 in the vehicle width direction and is engaged with the engagement portion 78 of the stopper 64, so that the engagement portion 78 moves inward of the case 102 by a predetermined stroke or more. Block. For this reason, even if the shift lever 12 presses the P stopper portion 74 of the stopper 64, the shift lever 12 cannot move to a position in the gate groove 62 and cannot move to a position corresponding to the R range after passing through the position. Therefore, the shift lever 12 is reliably prevented from moving from the P range to the R range.

On the other hand, for example, when the sensor detects that the vehicle occupant has depressed the brake pedal while the vehicle is stopped, and the coil 118 is energized by the shift lock computer, the lock member together with the cam member 132 is used. 110 is moved forward of the vehicle, and the lock portion 112 is disengaged from the predetermined position on the left side of the guide hole 104 in the vehicle width direction to the front side of the vehicle. (See FIG. 10). Therefore, the shift lever 12 can move to the position (the state shown in FIG. 7). Furthermore, moving from the state to the shift lever 12 rearward the position (arrow Y ₂ direction) Operation to be gate trench 62, the shift lever 12 is changed to the P range.

Here, even when the shift lever 12 is moved from the P range to the R range, the stopper 64 returns to the locked position again by the urging force of the coil spring 92, and the urging force of the coil spring 120. As a result, the cam member 132 and the lock member 110 move toward the rear of the vehicle, and each returns to a predetermined position on the left side of the guide hole 104 in the vehicle width direction (the state shown in FIG. 8).

As described above, in the present shift lever device 10, the stopper 64 is moved by the pressing force when the shift lever 12 is operated, and the locking member 110 is further moved by the pressing force from the stopper 64. The magnetic force (attraction force) of 100 (electromagnet 116) is
32 simply needs to be adsorbed. Therefore, compared with a conventional shift lock mechanism solenoid in which a plunger is moved by a magnetic force (attraction force) to operate a stopper, the power required when energizing the solenoid 100 (electromagnet 116) can be reduced. Therefore, the size of the electromagnet 116 can be reduced as compared with the conventional solenoid of the shift lock mechanism, and the overall shift lock mechanism can be downsized.

When the shift lever 12 is operated, the stopper 64 is moved by the pressing force, and when the pressing force is released, the stopper 64 returns to the locked position by the urging force of the coil spring 92. It is not necessary to directly connect the plunger 128 and the stopper 64 with a link mechanism including an arm, a rod, and the like unlike the conventional shift lock mechanism. For this reason, the number of parts can be significantly reduced, and the cost can be significantly reduced. In addition, since the shift lock and the release thereof can be reliably performed with a simple structure, it is not necessary to perform a strict control of the precision of parts, and the cost can be reduced in this sense.

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

FIG. 12 shows a shift lever device 170 to which the shift lock mechanism according to the second embodiment of the present invention is applied.
Is shown in an exploded perspective view. As shown in this figure, in the shift lever device 170, the longitudinal direction is set in the vehicle width direction (the directions of arrows X ₁ and X ₂ ) at an intermediate portion in the longitudinal direction of the shift lever 12 and below the lower housing 42. Guide member 176 is provided. This guide member 17
6 is locked to the shift lever 12 by a pin 186 extending in the longitudinal direction of the vehicle (the directions of arrows Y ₁ and Y ₂ ), and is rotatable around the pin 186. Further, from the longitudinal end portions of the guide member 176 pins 178, 180 is extended downwardly (arrow Z ₂ direction). Further, cylindrical caps 182 and 184 are fitted into these pins 178 and 180, respectively.

On the other hand, a plate-like strength gate 190 is arranged between the lower housing 42 and the base 28. Here, FIG. 13 is an enlarged perspective view of the strength gate 190, and FIGS.
A plan view of 90 is shown. As shown in these figures, a rectangular shape which is longitudinal in the vehicle front-rear direction (arrows Y ₁ and Y ₂ ) at the center of the strength gate 190 in the width direction (arrows X ₁ and X ₂ ). An opening 192 is formed. The opening 192 is formed corresponding to the shift groove 40 of the upper housing 36, and the shift lever 1
2 is formed so that the shift lever 12 can move sufficiently inside the opening 192 even when the shift lever 12 moves zigzag inside the shift groove 40. Further, on the left and right both sides of the opening 192 (i.e., the arrows X _1, X ₂ direction), the gate trench 194,1
96 are formed. These gate grooves 194, 19
6 is formed in a zigzag shape bent in the front-rear direction and the width direction of the vehicle similarly to the shift groove 40 of the upper housing 36, and the pins 178 and 180 are respectively inserted from above. The width of each of the gate grooves 194 and 196 is slightly larger than the diameter of the pins 178 and 180 when the caps 182 and 184 are fitted. For this reason, the pins 178 and 180 are
4 and 196 are prevented from moving in the width direction, and when the shift lever 12 is operated, the pins 178 and 180 are always in the gate groove 1.
The shift lever 12 moves while being guided by the guides 94 and 196, and the pin 17 moves to a predetermined position in the gate grooves 194 and 196.
The shift range of the automatic transmission is changed when 8, 180 is reached.

Also, the gate groove 19 on the strength gate 190
The left side of the 4 (arrow X ₂ direction side) is disposed a stopper 198. The stopper 198 includes the stopper 64 of the shift lever device 170 according to the first embodiment.
An N stopper portion 68 and a P stopper portion 74 are formed substantially in the same manner as in the first embodiment. In addition, the stopper 198 is connected to a pin 20 provided behind the gate groove 194 on the strength gate 190.
It is pivotally supported at 0. A torsion spring 202 is fitted into the pin 200. One end of the torsion spring 202 is fixed on the strength gate 190 and the other end is fixed on the lower surface side of the stopper 198.
The stopper 198 is always urged toward the gate groove 194 with the axis of 00 as the axis.

Further, from the front end of the P stopper 74 of the stopper 198, an engaging portion 78 in the form of a narrow rectangular bar extends like the stopper 64, and a guide formed on the case 102 of the solenoid 100. It has entered the hole 104.

The opening 192 on the strength gate 190
Front pin 94 (arrow Y ₁ direction side) of stopper 1
98, and is erected in correspondence with the P stopper portion 74 of N.
In the state where the stopper 68 and the P stopper 74 are located at the lock position above the gate groove 62 (the solid line state in FIG. 13), the pin 94 contacts the P stopper 74 and the stopper 1
98 is prevented from further moving to the gate groove 196 side.

Further, the gate groove 1 on the strength gate 190
On the right side of the 96 (direction of arrow X _1), it is pressed by the pin 180 in a state in which the shift lever 12 is positioned in the P range by ON
A switch 210 that is in the ON state and a switch 212 that is pressed by the pin 180 when the shift lever 12 is in the D range and is in the ON state are provided. The shift lever is turned on or off according to the ON / OFF state of these switches 210 and 212. Twelve positions are detected.

In the shift lever device 170 having the above configuration, the shift lever 12 (FIG. 14) is shifted to the N range.
When moving the illustrated state) to the R range, first pushes the shift lever 12 to the leftward (direction of arrow X _2). As a result, the pins 178, 180 are moved to the gate grooves 194, 196.
You will be guided to and move to the left. Here, when the pin 178 moves to the left, the pin 178
It comes into contact with the stopper portion 68 and presses the stopper 198 to the left. Thereby, the engaging portion 78 of the stopper 198
Further enters the inside of the case 102 of the solenoid 100 and presses the end 132A of the cam member 132 leftward. Here, when the coil 118 of the electromagnet 116 is not energized, the main body 128A of the plunger 128 is slidable inside the electromagnet 116, similarly to the shift lever device 10 according to the first embodiment. Even if the cam member 132 moves due to the pressing force from the joint portion 78 (stopper 198), the lock portion 112 of the lock member 110 is located at a predetermined position on the left side of the guide hole 104 in the vehicle width direction, and the engagement of the stopper 198 is performed. Engagement with the portion 78 prevents the engagement portion 78 from moving inside the case 102 (the state shown in FIG. 9). Therefore, by operating the shift lever 12, the pin 1
Even if 78 presses the N stopper 68 of the stopper 198, the pin 178 cannot move to the left, and the shift lever 12
From the N range to the R range.

On the other hand, for example, when the vehicle detects that the vehicle occupant depresses the brake pedal and the vehicle is decelerated to a predetermined speed or less, and the shift lock computer turns on the coil 118, The main body 128A of the plunger 128 is
6, the main body 128A of the plunger 128 and the electromagnet 116 are integrated, so that the pin 178 is
When the engaging portion 78 of the stopper 198 moved by the pressing force presses the cam member 132, the lock member 110 moves together with the cam member 132 to the front of the vehicle, and the lock portion 112 The vehicle 104 retreats from a predetermined position on the left side in the vehicle width direction to the vehicle front side. Therefore, the engaging portion 78 further enters the inside of the case 102 by the pressing force from the pin 178 (shift lever 12) (the state shown in FIG. 10), and the stopper 198 moves to the left (the state shown in FIG. 15). Then, moving the pin 178 by operating the shift lever 12 rearward (arrow Y ₂ direction) from this state to the rear, the shift lever 12 is changed to R-range (Fig. 16 shown state).

When the shift lever 12 is moved to the R range, the stopper 198 released from the pressing force of the pin 178 (shift lever 12) returns to the locked position again by the urging force of the torsion coil spring 202. I do. When the stopper 198 returns to the lock position, the engaging portion 78 of the stopper 198 moves outward of the case 102 and the pressing force from the engaging portion 78 to the cam member 132 is released. The biasing force of the spring 120 causes the cam member 132 and the lock member 110 to move rearward in the vehicle, and each returns to a predetermined position on the left side of the guide hole 104 in the vehicle width direction (the state shown in FIG. 8).

Meanwhile, when moving the shift lever 12 is shifted to the P range (FIG. 17 shown state) R-range, first pushes the shift lever 12 to the leftward (direction of arrow X _2). As a result, the pins 178 and 180 are guided by the gate grooves 194 and 196 and move to the left. here,
When the pin 178 moves to the left, the pin 178 comes into contact with the P stopper portion 68 of the stopper 198, and the stopper 19
8 is pressed to the left. Thereby, the stopper 64
The engaging portion 78 further enters the inside of the case 102 of the solenoid 100, and the engaging portion 78
Press 32A.

Here, similarly to the case where the shift lever 12 is moved from the P range to the R range, the electromagnet 1
When the sixteen coils 118 are not energized, the lock member 11
The lock portion 112 is located at a predetermined position on the left side of the guide hole 104 in the vehicle width direction and is engaged with the engagement portion 78 of the stopper 198.
Even if the pin 178 pushes the P stopper 68 of the stopper 198 by operating the shift lever 12 in order to prevent the shift lever 12 from moving inward, the pin 178 cannot move to the left, and the shift lever 12 moves out of the P range. Movement to the R range is prevented.

On the other hand, for example, when the vehicle is stopped,
Sensor detects the occupant depressing the brake pedal
And the shift lock computer activates the coil 118
When the power is turned on, the engaging portion 7 of the stopper 198 is
8 presses the cam member 132 and the cam member 132
The locking member 110 moves to the front of the vehicle
From the predetermined position on the left side of the guide hole 104 in the vehicle width direction.
Pin 178 (shift lever 1)
By the pressing force from 2), the engaging portion 78 is further moved to the case 10.
2 (shown in FIG. 10), and the stopper 19
8 moves to the left (the state shown in FIG. 18). Then this
From the state, move the shift lever 12 backward (arrow Y _TwoManeuver to direction)
When the pin 178 is moved backward, the shift lever 1
2 is changed to the R range (the state shown in FIG. 16).

Here, even when the shift lever 12 is moved from the P range to the R range, the stopper 198
Is returned to the locked position again by the urging force of the torsion coil spring 202, and the cam member 132 and the lock member 110 move rearward of the vehicle by the urging force of the coil spring 120, and each of the cam members 132 and the guide holes 104 It returns to a predetermined position on the left side in the width direction (the state shown in FIG. 8).

As described above, also in the present shift lever device 170, the stopper 198 is moved by the pressing force at the time of operating the shift lever 12, and the lock member 110 is further moved by the pressing force from the stopper 198. The magnetic force (attraction force) of 100 (electromagnet 116) only needs to be able to simply attract cam member 132. Therefore, compared with a conventional shift lock mechanism solenoid in which a plunger is moved by a magnetic force (attraction force) to operate a stopper, the power required when energizing the solenoid 100 (electromagnet 116) can be reduced. Therefore, the size of the electromagnet 116 can be reduced as compared with the conventional solenoid of the shift lock mechanism, and the overall shift lock mechanism can be downsized.

When the shift lever 12 is operated, the stopper 198 is moved by the pressing force, and when the pressing force is released, the stopper 198 is returned to the locked position by the urging force of the torsion coil spring 202. It is not necessary to directly connect the plunger 128 and the stopper 198 by a link mechanism including an arm, a rod, or the like unlike the conventional shift lock mechanism. For this reason, the number of parts can be significantly reduced, and the cost can be significantly reduced. In addition, since the shift lock and the release thereof can be reliably performed with a simple structure, it is not necessary to perform a strict control of the precision of parts, and the cost can be reduced in this sense.

In each of the above embodiments, the solenoid 100 is applied as the locking means and the electromagnet 116 is applied as the fixing means. However, the configurations of the locking means and the fixing means are not limited to this. For example, a motor integrated with either the cam member 132 or the lock member 110 is applied as a fixing means, and when the motor is energized and the output shaft of the motor rotates, the engaging member connected to the output shaft becomes a cam member. A motor device having a configuration in which the cam member 132 and the lock member 110 are integrated with each other by engaging the other of the lock member 132 and the lock member 110 may be applied as the lock means.

[0063]

As described above, in the shift lock mechanism of the shift lever device of the present invention, the stopper moves by the pressing force from the shift lever, and the lock member moves by the pressing force from the stopper. Unlike the shift lock mechanism, it is not necessary to move the lock member or the stopper by the attraction force of the solenoid, and a large amount of electric power is not required when the lock means is energized. For this reason, it is possible to reduce the size of the locking means as compared with the solenoid applied to the conventional shift lock mechanism, and to reduce the size of the entire shift lock mechanism.
