Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a key interlock mechanism used for a shift operation of a transmission in a vehicle, and a shift lever device provided with a shift lock mechanism.
[0002]
[Prior art]
Recently, the automatic transmission of a vehicle has become a multi-speed transmission specification, and there is a tendency that a large number of shift ranges are set. Therefore, there is a demand for a shift lever device that can select a plurality of shift ranges that are set in large numbers.
[0003]
Such a shift lever device for shifting the automatic transmission of a vehicle has a so-called gate (zigzag operation) in which the shift lever is shifted not only in the vehicle front-rear direction but also in the vehicle left-right direction to select the shift position. ) Type shift lever device has been proposed.
[0004]
That is, the shift lever device of the zigzag operation type is configured so that the operation direction of the shift lever is set in the vehicle front-rear direction and the left-right direction (so-called zigzag), for example, when the shift lever is selected in the P shift range. The shift operation to move to the R shift range is possible by two operations of moving the vehicle in the vehicle left-right direction and then moving in the vehicle rearward direction.
[0005]
Further, a shift lever device equipped with an electric shift lock system is also used. This shift lock system includes an electric shift lock mechanism and an electric key interlock mechanism. In this electric shift lock mechanism, when an electric actuator such as a solenoid is provided in the vicinity of the shift lever inside the shift device main body installed on the floor of the vehicle, the shift lever is operated from the P shift range to another R shift range or the like. Unless the brake operation is performed, the actuator is engaged with the shift lever to prevent the shift operation to another shift range.
[0006]
In addition, the electric key interlock mechanism operates the key interlock solenoid mounted on the steering lock body of the steering column to restrict the movement of the cam linked to the key cylinder, so that the shift lever is located at a position other than the parking range position. Then, the lock pin is moved to the lock side, and only when the shift lever is at the parking range position, the key can be moved to the release side by the key interlock solenoid so that the ignition key can be pulled out.
[0007]
However, in a shift lever device having such a shift lock mechanism with an electric key interlock mechanism, the key interlock solenoid and the switch signal for detecting the parking position of the shift lever are transmitted to the key interlock solenoid and the shift side solenoid. Controllers and further expensive parts such as wire harnesses are required, and there is a drawback that the cost is increased as a whole, and further measures for this have been desired.
[0008]
[Problems to be solved by the invention]
In consideration of the above-described facts, the present invention includes a key interlock mechanism that can be surely set in a key interlock state under a specific condition with a simple configuration and that can be disposed compactly in a limited narrow space. The object is to obtain a shift lever device.
[0009]
[Means for Solving the Problems]
  A shift lever device according to claim 1 of the present invention provides:A shift lever that is interlocked to shift the vehicle transmission and that can select one of a plurality of shift ranges by a moving operation, a lock cam that operates in conjunction with the shift lever, and a required key operation And when the shift lever is in the parking position, when the stopper cam is rotated by a required operation of the key, the stopper cam is engaged with the stop wall of the lock cam. The shift lever is prevented from rotating outside the parking shift range, and is disengaged from the lock cam by an operation opposite to the required operation of the key, so that the shift lever can be moved outside the parking shift range. A locking cam arm configured to be provided on the stopper cam, and the shift lever When the detent pin attached to the P range is located in the P range recess of the detent hole, the detent pin is prevented from coming out of the P range recess and the stopper cam is rotated by the required operation of the key. And a detent pin configured to allow the detent pin to escape from the P-range recess.
[0010]
  By configuring as described above, the detent pin prevents the shift operation of the shift lever by preventing the detent pin from coming out of the P range recess of the detent hole, and the shift of the shift lever is prevented by the stopper cam stopping the rotation of the lock cam. Since the operation is blocked, the shift operation of the shift lever is double blocked, the structural strength of the shift operation blocking is increased, and the blocking operation is ensured.
[0011]
  Also, the detent pin of the shift lever does not operate the stopper cam and the key interlock mechanism, but operates independently. Therefore, the operating force of the knob button of the shift lever that operates this detent pin is used only for detent pin operation. It is possible to improve this knob button operation feeling by setting a small force.
