The vehicle engine may be stopped when the shift lever is in the manual operation guide groove. In this case, the shift lever is not positioned at the home position (H), but the vehicle system processes the shift lever as being positioned at the home position (H). For this reason, there is a problem in that the actual position of the shift lever and the position of the shift lever on the vehicle system are not matched.

Therefore, when the engine of the vehicle is stopped with the shift lever positioned in the manual operation guide groove, the shift switch device returns the shift lever to the home position (H), and the shift lever is operated unless a certain operation is performed. A technique to shift-lock so that it cannot be moved to the manual operation guide groove has been studied.

As an example of the technique, a technique using an eccentric cam can be considered. Specifically, an eccentric cam having a rotation shaft is provided in the axial direction of the shift lever, and the distance between the eccentric cam and the shift lever is changed by rotating the eccentric cam.
In this way, by rotating the eccentric cam in contact with the shift lever, the shift lever can be pressed toward the home position (H) and the shift lever can be returned to the home position (H). it can. Further, in the state where the shift lever is returned to the home position (H), the rotation of the eccentric cam is stopped at a predetermined lock position, thereby restricting the shift lever from moving to the manual operation guide groove, thereby enabling the shift lock. You can also

It is conceivable to use an electric motor for the rotation of the eccentric cam. Specifically, by supplying electric power and a drive signal to the electric motor, rotation driving of the eccentric cam is started by the electric motor, and supply of electric power or drive signal to the electric motor is stopped, thereby Stop the rotational drive of the eccentric cam.

However, the electric motor may rotate by inertia after completing the rotational drive of the eccentric cam. Due to the presence or absence of inertial rotation of the eccentric cam, variation occurs in the position where the eccentric cam stops, and the distance between the eccentric cam and the shift lever varies, and the shift lever returned to the home position (H) There is a possibility that the lock position for shift locking may vary.

Accordingly, the pressing portion 821 of the protruding portion 82 presses the protruding portion 14 of the shift lever 10 in the Y plus direction, and the neutral position (N) of the manual operation guide groove 911 is changed to the home position (H) of the central guide groove 913. The shift lever 10 is returned.
When the cam position

detection Hall ICs

33 and 34 detect that the rotation position of the projecting portion 82 is the restriction position, the forward rotation of the motor 60 is stopped according to the drive signal from the control section AA. As a result, the flat portion 822 of the projecting portion 82 maintains the state facing the protrusion 14 of the shift lever 10, and the shift lever 10 moves from the home position (H) to the manual operation guide groove 911. Is regulated.

Further, the shift switch device 1 reversely rotates the motor 60 according to the drive signal from the control unit AA when it is detected that a predetermined operation such as moving the shift lever 10 to the drive position is performed. The wheel member 70 is rotated counterclockwise on the XZ plane when viewed from the Y plus direction. As a result, the state in which the flat portion 822 faces the protruding portion 14 is eliminated, and the protruding portion 82 of the cam member 80 moves away from the protruding portion 14.
When the cam position

detection Hall ICs

33 and 34 detect that the rotation position of the protrusion 82 is the retracted position, the reverse rotation of the motor 60 is stopped according to the drive signal from the control unit AA. Thereby, the restriction | limiting of the movement of the shift lever 10 to the manual operation guide groove 911 is cancelled | released.

When viewed, the wheel member 70 is rotated clockwise on the XZ plane. Then, the protrusion 82 moves from outside the predetermined operation path range of the shift lever 10 into the predetermined operation path range, and the pressing portion 821 comes into contact with the protrusion 14 from the Z plus direction as shown in FIGS.

Even after the pressing portion 821 comes into contact with the protruding portion 14, the shift switch device 1 continues to rotate the motor 60 in a forward direction in accordance with the drive signal from the control portion AA. Then, the shift lever 10 is pressed in the Y plus direction by the pressing portion 821, and when viewed from the Y plus direction, as the wheel member 70 rotates clockwise on the XZ plane, the shift lever 10 moves to the manual operation guide groove 911. To the automatic operation guide groove 912 (in the Y plus direction), the central guide groove 913 is moved. The shift lever 10 is subjected to the force received by the contact pin 131 of the shift lever 10 from the moderation groove 92 at the timing before and after the position where the protrusion 82 contacts the protrusion 14 changes from the pressing portion 821 to the flat portion 822. Returns to the home position (H) of the central guide groove 913.
In the state where the shift lever 10 is returned to the home position (H) of the central guide groove 913, the flat surface portion 822 faces the projection portion 14 with a predetermined gap as will be described later with reference to FIG. To do. For this reason, when viewed from the Y plus direction, even if the wheel member 70 rotates clockwise on the XZ plane, the shift lever 10 does not move.

9 and 10 show the shift switch device 1 in a state where the rotation position of the protruding portion 82 of the cam member 80 is the restriction position. In this state, the shift switch device 1 detects that the rotation position of the projecting portion 82 is the restriction position by the cam position

Then, the plane portion 822 maintains a state facing the projection portion 14 with a predetermined gap, and the movement of the shift lever 10 from the home position (H) to the manual operation guide groove 911 is restricted. The

The operation of the shift switch device 1 when the parking switch is turned on with the shift lever 10 positioned at the neutral position (N) of the manual operation guide groove 911 has been described above with reference to FIGS. explained. When it is detected that a predetermined operation such as moving the shift lever 10 to the drive position has been performed, the shift switch device 1 reversely rotates the motor 60 according to the drive signal from the control unit AA, The above-described operation described with reference to FIGS. 5 to 10 is performed in the reverse order to the above-described case.

As described above, the shift switch device 1 includes the motor 60, the wheel member 70 driven by the motor 60, and the cam member 80 that moves in synchronization with the wheel member 70. Further, when it is detected that the parking switch is turned on, if it is detected that the shift lever 10 is positioned at the neutral position (N) of the manual operation guide groove 911, the drive signal from the control unit AA is detected. By rotating the motor 60 forward, the wheel member 70 is rotated clockwise on the XZ plane when viewed from the Y plus direction. Then, the shift lever 10 is returned to the home position (H) of the central guide groove 913 by moving the protrusion 82 from outside the operation path range of the shift lever 10 into the operation path range.
For this reason, the rotation of the wheel member 70 is stopped after the shift lever 10 is returned to the home position (H) of the central guide groove 913, so that the protrusion 82 is moved close to the shift lever 10. Can be opposed to each other. Therefore, the variation in the lock position where the shift lever 10 returned to the home position (H) of the center guide groove 913 is shift-locked can be suppressed.

In the shift switch device 1, when the shift lever 10 is moved along the central guide groove 913, the shift lever 10 moves in a predetermined operation path. When the shift switch device 1 detects that the parking switch is turned on and detects that the shift lever 10 is positioned at the neutral position (N) of the manual operation guide groove 911, the control unit AA The wheel member 70 is rotated clockwise on the XZ plane when viewed from the Y plus direction by causing the motor 60 to rotate forward according to the drive signal from. Then, the shift lever 10 is returned to the home position (H) of the central guide groove 913 by moving the protrusion 82 from outside the predetermined operation path range of the shift lever 10 into the predetermined operation path range.
Therefore, the protrusion 82 is brought into contact with the shift lever 10 positioned at the neutral position (N) of the manual operation guide groove 911, and the shift lever 10 is pressed by the protrusion 82, so that the neutral of the manual operation guide groove 911 is neutralized. The shift lever 10 can be returned from the position (N) to the home position (H) of the central guide groove 913.

In the shift switch device 1, the shift lever 10 is provided with a protrusion 14 that protrudes toward the neutral position (N) of the manual operation guide groove 911 at the home position (H) of the central guide groove 913.

Further, the pressing portion 821 is brought into contact with the protruding portion 14 of the shift lever 10 from the axial direction of the shift lever 10, and the flat portion 822 is provided so as to face the protruding portion 14.
For this reason, by rotating the cam member 80, the protruding portion 82 can be brought into contact with the protruding portion 14 from the axial direction of the shift lever 10, and the shift lever 10 can be pressed by the protruding portion 82.

Further, the shift switch device 1 has a flat surface portion 822 so as to have a predetermined width in the rotation direction of the cam member 80.
For this reason, even if the cam member 80 is rotated in a state where the flat portion 822 faces the protrusion 14 of the shift lever 10, the flat portion 822 continues to face the protrusion 14, and the flat portion 822 and the protrusion 14. Can keep the distance between. Therefore, the presence / absence and variation of the inertial rotation of the motor 60 can be absorbed by the plane portion 822, and the variation in the lock position for shifting and locking the shift lever 10 returned to the home position (H) of the central guide groove 913 is suppressed. be able to.

Further, the shift switch device 1 is provided with the flat surface portion 822 in parallel with the axial direction of the shift lever 10.
For this reason, even if the cam member 80 is rotated in a state where the flat surface portion 822 faces the protrusion portion 14 of the shift lever 10, the distance between the flat surface portion 822 and the protrusion portion 14 can be kept constant. Accordingly, the presence / absence and variation of inertial rotation of the motor 60 can be absorbed by the plane portion 822, and the variation in the lock position for shifting and locking the shift lever 10 returned to the home position (H) of the central guide groove 913 is further increased. Can be suppressed.

Further, the shift switch device 1 connects the flat portion 822 to one end of the pressing portion 821 in the rotation direction of the cam member 80. Further, the pressing portion 821 is formed so as to incline away from the shift lever 10 as it goes from one end to the other end of the pressing portion 821 in the rotation direction of the cam member 80.
For this reason, even if the pressing portion 821 is in contact with the protruding portion 14, the cam member 80 can be rotated by the inclination of the pressing portion 821, and the portion that contacts the protruding portion 14 can be moved from the pressing portion 821. The plane portion 822 can be changed.

The shift switch device 1 also provides the cam member 80 within the inner diameter of the wheel member 70 and rotates the wheel member 70 integrally with the rotation axis of the wheel member 70 as the center of rotation.
For this reason, since the wheel member 70 and the cam member 80 can be rotated on the same plane, a space can be used effectively and the shift switch apparatus 1 can be reduced in size.

In addition, the shift switch device 1 includes cam position

detection Hall ICs

33 and 34 that detect the rotational position of the protrusion 82 of the cam member 80 on the board 30 on which the

Hall ICs

31 and 32 that detect the position of the shift lever 10 are mounted. Has been implemented.
For this reason, the shift switch apparatus 1 can be reduced in size.

In the above-described embodiment, the wheel member 70 rotates on a plane perpendicular to the Y direction. However, the present invention is not limited thereto, and in other words, along the central guide groove 913. It suffices to rotate it on a plane that intersects with the direction.

In the above-described embodiment, as described with reference to FIG. 3, the cam member 80 is provided separately from the wheel member 70, but is not limited thereto, and may be provided integrally with the wheel member 70.

Further, in the above-described embodiment, when the rotation position of the protrusion 82 is the restriction position, the flat portion 822 of the protrusion 82 is disposed to face the protrusion 14 of the shift lever 10 with a predetermined gap. . However, the present invention is not limited to this, and when the rotation position of the protrusion 82 is the restriction position, the flat surface portion 822 of the protrusion 82 may abut on the protrusion 14 of the shift lever 10. As a result, it is possible to prevent the shift lever 10 that has been returned to the home position (H) of the central guide groove 913 from rattling.
