[0002]

2. Description of the Related Art As this type of technology, for example,
There is a -7020 publication.

According to such a conventional example, since the position pin lock member and the actuating body are arranged vertically, the vertical size of the shift lever device of the automatic transmission becomes large, and by extension, the automatic transmission. This causes the position of the upper surface of the console box incorporating the shift lever device to rise.

Further, since the position pin directly receives the load for pushing and pulling the cable connected to the key lock device, the vertical movement of the position pin is controlled when the position of the shift lever is moved by the sliding resistance of the cable or the like. The button switch operation force becomes heavy. Moreover, there is a possibility of a return failure.

In view of the above-mentioned conventional example, it is an object of the present invention to provide a device for reducing the vertical size of a shift lever device of an automatic transmission and reducing the operating force of a button switch.

[0006]

A shift lever device for an automatic transmission according to the present invention includes a position plate fixed to a vehicle body and having a plurality of locking recesses such as a parking range,
One of a plurality of ranges of the automatic transmission can be selected by engaging with either a button switch swingably supported by the vehicle body and arranged at an upper end portion thereof or a lock recess of the position plate. A shift lever having a position pin that can be disengaged from the lock recess of the position plate by pressing the button switch, and is rotatable about the axis of the shift lever to enable disengagement of the position pin from the parking range. When the position of the key rotor of the cylinder lock is ON and the foot brake switch is ON, the rotor is moved so that the groove is aligned with the position of the position pin. A movable solenoid and a free end of the rotating body which is slidably supported substantially horizontally with respect to the vehicle body. An actuating body that can be moved in position by being pushed by a held lock pin, and one end allows the rotation of the key rotor and the lock position that restricts rotation of the key rotor from the on position side to the lock position side of the key rotor. A cable connected to a stopper movable to an unlock position and the other end of which is connected to the actuation body, and the stopper is constantly urged toward the lock position in the cylinder lock of the cable or the actuation body. The first urging means and the second urging means that constantly urges the rotating body in a direction to push the actuating body when the solenoid is in an off state.

[0007]

[Operation] According to this structure, the movement of the rotating body and the operating body that regulate the movement of the stopper in the cylinder lock is rotated about the axis of the shift lever and slides substantially horizontally with respect to the vehicle body. Therefore, the vertical size of the shift lever device of the automatic transmission can be small.

Further, since the load of pushing and pulling the cable connecting the key cylinder and the actuating body is distributed only to the actuating body and is not applied to the position pin, the means for urging the position pin can be light. ..

At the position where the actuating member is not pushed by the lock pin, the stopper in the cylinder lock is in the lock position for restricting the rotation of the key rotor from the on position side to the lock position side by the first urging means. Even if the engine start key is operated, it does not rotate to the lock position side, so the engine start key cannot be removed from the cylinder lock.

Next, when the button switch is pushed and the shift lever is rotated back and forth to release the force pushing the button switch with the position pin facing the parking range of the position plate, the position pin moves to the parking range. It enters and is held in the locked position. At this time, since the solenoid is off, the rotating body is rotated by the second biasing means and the groove is moved, so that the position pin cannot be removed from the parking range again. In addition, the lock pin pushes the actuating body, and the stopper in the cylinder lock is moved to the unlock position that allows the key rotor to rotate from the ON position side to the lock position side via the cable connected to the actuating body.

Therefore, when the engine start key is operated to rotate the key rotor of the cylinder lock to the lock position, the engine start key can be removed from the cylinder lock. In the parking state as described above, even if an attempt is made to shift-shift the shift lever from the parking range, the slide of the position pin in the disengagement direction is restricted by the rotating body so that the shift-change cannot be performed.

When shifting the shift lever from the parking range to the traveling range, the key rotor for the cylinder lock is moved from the lock position to O based on the operation of the engine start key.
Turn the brake switch by turning to the N position and depressing the foot brake. Then, the movement restriction of the stopper is released, and the stopper can be moved in the lock position direction, and at the same time, the actuating body can also be moved.

In this state, when the position pin is slid in the direction of releasing from the parking range of the position plate, the stopper is moved by the first urging means in the cylinder lock interlocking with this, and the cable is interposed. The moving body moves. Therefore, the position pin can be released from the parking range of the position plate, the shift lever can be shifted to the travel range, and the position pin can be engaged with the travel range at an arbitrary position.

Next, when the shift lever is set to a range other than the parking range in this way and the key rotor is rotated to the lock position side by operating the engine start key, the stopper is arranged at the lock position. As a result, this rotation is restricted and cannot be locked. In this case, the operating force applied to the key rotor of the engine start key is received by the stopper and is not transmitted to the cable.

The rotating body 6 is made of a synthetic resin material and is rotatably arranged around the axial center (FIGS. 2 to 4) of the compression rod 4c within the movement range of the position pin 5 of the shift lever 4. FIG. 1 is a perspective view, which is difficult to understand, but shows a state in which the position pin 5 is inserted, and this state means a state in which the position pin 5 is separated from the parking range P.
A groove portion 6a is formed so as to vertically penetrate therethrough.

The solenoid 8 corresponds to the shift lever 4
It is arranged on the bracket 14 arranged at a position lower than the disposition position of the rotating body 6, and the rod 8a is engaged with the rotating body 6 so as to be movable back and forth. When the solenoid 8 receives both a signal indicating that the position of the key rotor 7a of the cylinder lock 7 is on and a signal indicating that a foot brake switch (not shown) is on, the solenoid 8 receives the rod 8a.
Has a function of causing the rotating body 6 to move and aligning the groove portion 6a with the position of the position pin 5.

The actuating body 9 has a flat plate shape supported through elongated holes 9b and 9b so as to be slidable substantially horizontally with respect to pins 9a and 9a provided upright on a vehicle body (not shown), A lock pin 10 supported by the free end 6b of the rotating body 6.
An engaging portion 9c that is pushed by is formed. This engaging portion 9
c is the first opening 9ca into which the lock pin 10 is inserted.
And a portion 9cb that interferes with the lock pin 10 when the position pin 5 is vertically movable relative to the groove 6a of the rotary body 6 and the axis of the compression rod 4c of the shift lever 4 from the position 9cb. It is composed of a second opening 9cc which is linear on the center side, in other words, which is perpendicular to the first opening 9ca.

One end 11a of the cable 11 allows the key rotor 7a and the lock position (FIG. 1) for restricting the rotation of the key lock 7a of the cylinder lock 7 from the ON position ON side to the lock position LOCK side to rotate the key rotor 7a. The other end 11b is connected to the stopper 7b movable to the unlock position (FIG. 2) and the other end 11b is the engaging portion 9c of the actuating body 9.
Inner cable 11c connected to side 9d opposite to
And an outer cable 11d that covers the inner cable 11a.

The second urging means 13 is composed of a coil spring having one end supported by the rotating body 6 and the other end supported by a bracket 14 supporting the solenoid 8, and a force for expanding the solenoid 8 is provided. Although weaker, when the position pin 5 is not in the groove 6a of the rotating body 6 and the solenoid 8 is in the OFF state, the rotating body 6 is constantly urged with a force for moving the operating body 9. ..

The cylinder lock 7 is, for example, disclosed in Japanese Patent Laid-Open No. 63-63.
The key rotor 7a which is rotated by inserting and turning an ignition key (not shown) is provided inside the key cylinder 7c. There is. In addition, this key rotor 7a is operated by operating the ignition key.
This key can be inserted and removed, and the lock position LOCK locks the steering wheel, the accessory position ACC where the engine is stopped but the electric components such as the radio can be used, and the on-position ON when the engine is started. And a start position START for starting the engine.

The stopper 7b is the key cylinder 7
c inside the lock position L from the ON position ON side of the key rotor 7a via the cable 11.
When in the lock position (FIG. 1) that restricts the rotation to the OCK side, the coil spring 12 serving as the first urging means locates deep inside the key cylinder 7c, and the position pin 5 engages with the parking range P. When the actuating body 9 is moved by the rotating body 6 as shown in FIG. 4, the movement is transmitted via the cable 11 and moved against the coil spring 12 to rotate the key rotor 7a. It is arranged so that it can be moved to the unlocked position (Fig. 2).

The key rotor 7a is provided with a restriction portion 7aa which restricts the movement of the stopper 7b to the lock position when the lock position LOCK is set. Code 7
ab is the stopper 7 formed on the key rotor 7a.
It is a position control part in the lock position of b.

Coil spring 1 as the first urging means
2 is inside the cylinder lock 7, and the cable 11
Is a means for constantly urging the stopper 7b connected to the one end 11a toward the lock position, and this urging force is greater than the urging force of the third urging means (not shown) for raising the position pin 5. Is small. Further, the coil spring 12 may be wound around not the inside of the cylinder lock 7 but the side 9d of the actuation body 9 opposite to the engaging portion 9c.

Next, the operation of the embodiment will be described. According to this structure, the movements of the rotating body 6 and the operating body 9 that restrict the movement of the stopper 7b in the cylinder lock 7 are rotated about the axis of the compression rod 4c of the shift lever 4 and are transmitted to the vehicle body (not shown). Since it slides substantially horizontally, the vertical size of the shift lever device 1 of the automatic transmission can be small.

Further, since the load of pushing and pulling the cable 11 connecting the key cylinder 7c and the operating body 9 is distributed only to the operating body 9 and is not applied to the position pin 5, the means for urging the position pin 5 is Light and good.

At the position where the operating body 9 is not pushed by the lock pin 10, the stopper 7b in the cylinder lock 7 is
Is in the lock position for restricting the rotation of the key rotor 7a from the ON position ON side to the lock position LOCK side by the first urging means 12, therefore, even if the engine start key (not shown) is operated, the lock position LOCK side is set. The engine start key (not shown) cannot be removed from the cylinder lock 7 because it does not rotate.

Next, when the button switch 4b is pushed to rotate the shift lever 4 back and forth to release the force pushing the button switch 4b with the position pin 5 facing the parking range P of the position plate 2, the position is released. The pin 5 enters the parking range P and is held at the lock position.
At this time, since the solenoid 8 is off, the rotating body 6 is rotated by the second biasing means 13 and the groove portion 6a is moved, so that the position pin 5 cannot be removed from the parking range P again. Further, the lock pin 10 pushes the operating body 9, and the cylinder lock 7 is pushed through the cable 11 connected to the operating body 9.
The inner stopper 7b is moved to the unlocked position that allows the key rotor 7a to rotate from the ON position ON side to the lock position LOCK side.

Therefore, when the engine start key (not shown) is operated to rotate the key rotor 7a of the cylinder lock 7 to the lock position LOCK side, the engine start key (not shown) can be removed from the cylinder lock 7. ..

In the parking state as described above, even if an attempt is made to shift-shift the shift lever 4 from the parking range P,
The slide of the position pin 5 in the disengagement direction is restricted by the rotating body 6 so that the shift change cannot be performed.

When shifting the shift lever 4 from the parking range P to the traveling range D, the key rotor 7a of the cylinder lock 7 is moved from the lock position LOCK side to the on position ON side based on the operation of an engine start key (not shown). The brake switch (not shown) is turned on by rotating and turning on a foot brake (not shown).

Then, the movement restriction of the stopper 7b is released, and the stopper 7b can be moved in the lock position LOCK direction, and at the same time, the actuating body 9 can also be moved. In this state, when the position pin 5 is slid in the direction of releasing the position plate 2 from the parking range P, the stopper 7b is moved by the first biasing means 12 in the cylinder lock 7 in conjunction with this, and the cable 11 is moved. The actuating body 9 moves through.

Therefore, the position pin 5 is released from the parking range P of the position plate 2, and the shift lever 4 is released.
Can be shifted to the travel range D, and the position pin 5 can be engaged with the travel range D at an arbitrary position.

Next, when the shift lever 4 is set to a range other than the parking range P in this way and the key rotor 7a is rotated to the lock position LOCK side by the operation of the engine start key (not shown), the stopper Since 7b is arranged at the lock position LOCK, this rotation is restricted and it cannot be locked. In this case, the operating force applied to the key rotor 7a of the engine start key (not shown) is received by the stopper 7b and is not transmitted to the cable 11.
