Patent document 1: japanese patent laid-open publication No. 2014-151708
An engine of a vehicle may be stopped in a state where a shift lever is located in a manual operation guide groove. At this time, although the shift lever is not at the origin position (H), the system of the vehicle is handled as the shift lever being at the origin position (H). Therefore, there is a problem that the actual position of the shift lever does not coincide with the position of the shift lever in the vehicle system.
Here, a shift lock technique is discussed in which, 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 original position (H), and the shift lever cannot be moved to the manual operation guide groove unless a predetermined operation is performed.
As an example of the above technique, an eccentric cam is considered. Specifically, an eccentric cam having a rotary shaft in the axial direction of the shift lever is provided, 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 a state of being in contact with the shift lever, the shift lever is pressed toward the origin position (H), and the shift lever can be returned to the origin position (H). Further, in a state where the shift lever is returned to the original position (H), by stopping the rotation of the eccentric cam at a predetermined lock position, the shift lever can be restricted from moving to the manual operation guide groove, and the shift lock can be performed.
The rotation of the eccentric cam described above is considered to be performed by a motor. Specifically, the electric power and the drive signal are supplied to the motor, the motor starts the rotational drive of the eccentric cam, and the electric power and the drive signal are stopped from being supplied to the motor, thereby stopping the rotational drive of the eccentric cam by the motor.
However, the motor is inertially rotated after the rotation driving of the eccentric cam is completed. Due to the presence or absence of inertial rotation and the deviation of the eccentric cam, the position at which the eccentric cam stops rotating may be deviated, the interval between the eccentric cam and the shift lever may be deviated, and the lock position at which the shift lever returned to the origin position (H) is shift-locked may be deviated.

Detailed Description
A shift switch device 1 according to an embodiment of the present invention will be described below with reference to fig. 1 to 10.
Each of fig. 1 to 10 is a schematic view, and the size and shape of each portion are exaggerated as appropriate for easy understanding.
In the following description, specific numerical values, shapes, materials, and the like are described, but these may be appropriately changed.
For convenience of explanation and understanding, the XYZ rectangular coordinate system is provided in each of the drawings shown below, but the XYZ rectangular coordinate system is set merely for the purpose of uniform explanation of the orientation in the drawings, and is not absolute coordinates.
Fig. 1 is an exploded perspective view of the shift switch device 1. The shift switch device 1 is mounted on a vehicle to switch a shift position of the vehicle, and includes a shift lever 10, a cover 21, a shift base 22, a sensor cover 23, a base cover 24, a base plate 30, a rotor member 40, an arm member 50, a motor 60 as an actuator, a wheel 70, a cam member 80 as a cam portion, and a guide housing 90.
The shift lever 10 is a lever that can be operated by a driver, and is held by a holder 221 and a holder cover 222 attached to the shift base 22 so as to be able to swing with the ball portion 12 provided on the lower side (negative Z side) as a fulcrum. As shown in fig. 5, the direction in which the shift lever 10 can be swung, that is, the operation path of the shift lever 10 is restricted by a guide groove 91 formed in the guide housing 90. Specifically, the operation path of the shift lever 10 is limited to: a shift direction in which an upper end portion (end portion on the Z positive direction side) of the shift lever 10 moves in the X direction; and a selection direction in which the upper end portion of the shift lever 10 moves in the Y direction.
The guide groove 91 includes: a manual operation guide groove 911 in which the shift lever 10 is located in the manual operation mode; an automatic operation guide groove 912 in which the shift lever 10 is located in the automatic operation mode; and a central guide groove 913 connecting the manual operation guide groove 911 and the automatic operation guide groove 912.
The manual operation guide groove 911 is provided with a plurality of operation positions such as an upshift position (+), a neutral position (N), and a downshift position (-). The automatic operation guide groove 912 has a plurality of operation positions such as a forward position, a neutral position, and a reverse position. The center guide groove 913 is provided so that the neutral position (N) of the manual operation guide groove 911 and the neutral position of the automatic operation guide groove 912 are connected, and the center guide groove 913 is provided with the origin position (H) as the neutral position.
In the present embodiment, the neutral position (N) of the manual operation guide groove 911 is set as a predetermined operation position, and the center guide groove 913 is set as a predetermined operation path. The region through which the shift lever 10 passes when the shift lever 10 is operated along the guide groove 91 is set as the operation path range. The region through which the shift lever 10 passes when the shift lever 10 is operated along the center guide groove 913 is set as the predetermined operation path range among the operation path ranges.
Further, a restricting member 13 is mounted on the shift lever 10. An abutment pin 131 is provided at the lower end (end on the negative Z direction side) of the regulating member 13. A plurality of restricting grooves 92 are formed in the guide housing 90 at positions corresponding to the swing positions of the shift lever 10. The abutment pin 131 abuts against the regulation groove 92 in a biased state.
Therefore, when the abutment pin 131 moves to the adjacent restricting groove 92 when the shift lever 10 is operated, a moderate resistance feeling (restricting feeling, knocking feeling) can be given to the driver, and the operation feeling can be improved. Further, the operating position of the shift lever 10 is held by the engagement of the abutment pin 131 with the restriction groove 92.
Further, by limiting the operation path of the shift lever 10 and by abutting the abutment pin 131 in a biased state, a load due to an operation force when the shift lever 10 is operated by the driver is applied from the shift lever 10 to the guide housing 90. As shown in fig. 1, the guide housing 90 is firmly fixed to the shift base 22 and the base cover 24 by the lock pin 93 and the retaining nut 94.
The ball portion 12 is integrated with the shift lever 10 by insertion of the shift lever 10, and the overall shape of the ball portion 12 is substantially spherical, although it is provided with a weight-reduced shape. An engaging groove 121 having a slit-shaped opening is formed on the Y-negative side of the ball portion 12, and an engaging groove 122 having a slit-shaped opening is formed on the X-negative side of the ball portion 12.
The engaging piece 41 of the rotor member 40 is slidably engaged with the engaging groove 121, and the engaging piece 41 rotates following the swing in the shift direction (X direction) of the shift lever 10. The hall IC31 as a shift lever position detection unit mounted on the substrate 30 detects the rotation angle of the rotor member 40.
The engaging piece 51 of the arm member 50 is slidably engaged with the engaging groove 122, and the engaging piece 51 rotates following the swing in the selection direction (Y direction) of the shift lever 10. The hall IC32 as a shift lever position detection unit mounted on the board 30 detects the rotational position of the arm member 50.
The substrate 30 is formed with a control circuit 35 and a connector 36 that receive detection results from the hall ICs 31, 32. The control circuit 35 is electrically connected to a control part AA mounted on the vehicle via a connector 36. The control part AA determines the rocking position of the shift lever 10 in the shift direction based on the detection result of the hall IC31 received from the control circuit 35, and determines the rocking position of the shift lever 10 in the selection direction based on the detection result of the hall IC32 received from the control circuit 35, to determine the operation position of the shift lever 10.
The shift lever 10 is provided with a projection 14, and the projection 14 projects so as to face the neutral position (N) of the manual operation guide groove 911, i.e., the negative Y direction at the origin position (H) of the center guide groove 913.
The cover 21 is attached to the shift base 22 from the positive Z direction. A through hole 211 through which the shift lever 10 passes is formed in the upper surface (side surface on the positive Z direction side) of the cover 21, and the through hole 211 is covered with the inlet cover 15. The inlet/outlet cover 15 is formed with a through hole 151 through which the shift lever 10 passes. As shown in fig. 2, a shift knob 11 is attached to a portion of the shift lever 10 protruding from the through-hole 151 and the through-hole 211.
Returning to fig. 1, the motor 60 is supplied with electric power via the control circuit 35 in accordance with a drive signal output from the control unit AA, and rotates the output shaft in the forward or reverse direction. A worm wheel 61 that rotates integrally with the output shaft is provided on the output shaft of the motor 60. The worm wheel 61 is engaged with a wheel 70 as shown in fig. 4.
Returning to fig. 1, the wheel 70 is mounted on the shift base 22 by a gear cover 224 in a state of being rotatably supported by a rotary shaft 223 provided on the shift base 22. A cam member 80 is mounted on the wheel 70. The wheel 70 and the cam member 80 will be described below with reference to fig. 3.
Fig. 3 is an exploded perspective view of the wheel 70 and the cam member 80.
The wheel 70 includes a bearing portion 71 through which the rotating shaft 223 is inserted and a cam fixing pawl portion 72.
The cam member 80 is accommodated in the inner diameter of the wheel 70, and is fixed to the wheel 70 by the cam fixing pawl 72 in a state where the relative position with respect to the wheel 70 is determined by the rotational direction positioning rib 83. Therefore, the cam member 80 rotates integrally with the wheel 70 with the rotation shaft 223 as the center of rotation.
In addition, since the rotation shaft 223 extends in the Y direction, the wheel 70 rotates on a plane perpendicular to the Y direction, that is, on a plane intersecting with the direction along the central guide groove 913. Accordingly, the cam member 80 also rotates on a plane intersecting the direction along the central guide groove 913.
The cam member 80 includes: an annular base 81 having the rotational direction positioning rib 83 formed on an end edge thereof; and a protrusion 82 protruding from the base 81.
The base 81 has an insertion hole 811 through which the bearing portion 71 of the wheel 70 is inserted.
The protruding portion 82 protrudes from the base 81 in the Y-positive direction, i.e., the extending direction of the central guide groove 913, in a state where the cam member 80 is fixed to the wheel 70 that is pivotally supported by the rotary shaft 223. The protruding portion 82 includes a pressing portion 821 and a flat portion 822.
The flat portion 822 is provided so as to be able to face the protrusion 14 of the shift lever 10. Specifically, the flat portion 822 is provided parallel to the axial direction of the shift lever 10, and has a predetermined width in the rotational direction of the cam member 80, in other words, in the direction along the annular end edge of the base 81.
One end of the pressing portion 821 in the rotation direction of the cam member 80 is connected to the flat portion 822. The pressing portion 821 is formed to be inclined in the Y negative direction away from the shift lever 10 from one end of the pressing portion 821 in the rotation direction of the cam member 80 to the other end.
Specifically, referring to fig. 7 and 8, the pressing portion 821 abuts against the protrusion 14 of the shift lever 10 from the axial direction of the shift lever 10.
The magnet 84 is held by the wheel 70 and the cam member 80. As shown in fig. 1, cam position detection hall ICs 33, 34 as detection means are mounted on the base plate 30 at positions facing the tracks on which the magnets 84 pass when the wheel 70 rotates. The cam position detection hall ICs 33 and 34 detect the rotation position of the protruding portion 82 by detecting the magnetic flux of the magnet 84, and transmit the detection result to the control portion AA via the control circuit 35 and the connector 36.
When the shift switch device 1 described above detects that the parking switch as a preset vehicle condition is turned on, and when it detects that the shift lever 10 is located at the neutral position (N) of the manual operation guide groove 911, the motor 60 is rotated in the forward direction in accordance with the drive signal from the control unit AA, and the wheel 70 is rotated clockwise on the XZ plane as viewed from the Y forward direction. In this way, pressing part 821 of projecting part 82 presses projecting part 14 of shift lever 10 in the positive Y direction, and returns shift lever 10 from the neutral position (N) of manual operation guide groove 911 to the origin position (H) of center guide groove 913.
When the cam position detection hall ICs 33 and 34 detect that the rotational position of the protruding portion 82 is the limit position, the forward rotation of the motor 60 is stopped in response to a drive signal from the control unit AA. In this way, the flat portion 822 of the protruding portion 82 maintains a state of facing the protrusion 14 of the shift lever 10, and restricts the shift lever 10 from moving from the origin position (H) to the manual operation guide groove 911.
When the shift switch device 1 detects a predetermined operation of moving the shift lever 10 to the forward position, the motor 60 is rotated in the reverse direction in accordance with a drive signal from the control unit AA, and the wheel 70 is rotated in the counterclockwise direction on the XZ plane as viewed from the positive Y direction. Thus, the state where the flat portion 822 faces the protrusion 14 is released, and the protruding portion 82 of the cam member 80 is separated from the protrusion 14.
When the cam position detection hall ICs 33 and 34 detect that the rotational position of the protruding portion 82 is the retracted position, the reverse rotation of the motor 60 is stopped in response to a drive signal from the control unit AA. Thus, the restriction on the movement of the shift lever 10 to the manual operation guide groove 911 is released.
The operation of the shift switch device 1 when the parking switch is turned on in a state where the shift lever 10 is located at the neutral position (N) of the manual operation guide groove 911 will be described specifically below with reference to fig. 5 to 10.
Fig. 5 and 6 show shift switch device 1 in a state where shift lever 10 is located at the neutral position (N) of manual operation guide groove 911. In this state, the rotational position of the protruding portion 82 of the cam member 80 is the escape position, and the protruding portion 82 is away from the protruding portion 14 of the shift lever 10.
In the state shown in fig. 5 and 6, when it is detected that the parking switch is turned on, the shift switch device 1 rotates the motor 60 in the forward direction in accordance with the drive signal from the control section AA, and rotates the wheel 70 clockwise on the XZ plane as viewed from the positive Y direction. In this way, when projecting portion 82 moves from outside the predetermined operation path range of shift lever 10 to inside the predetermined operation path range, pressing portion 821 abuts against projecting portion 14 from the positive Z direction as shown in fig. 7 and 8.
When pressing portion 821 abuts on projection 14, shift switch device 1 continues to rotate motor 60 in the forward direction according to the drive signal from control unit AA. Thus, the shift lever 10 is pressed by the pressing portion 821 in the Y positive direction, and the wheel 70 rotates clockwise on the XZ plane when viewed from the Y positive direction, whereby the shift lever 10 moves from the manual operation guide groove 911 to the automatic operation guide groove 912 (in the Y positive direction) in the center guide groove 913. Then, at the position of the protruding portion 82 in contact with the protruding portion 14, the lever 10 is returned to the origin position (H) of the center guide groove 913 at the front-rear timing when the pressing portion 821 is changed to the flat surface portion 822, by the force received by the contact pin 131 of the lever 10 from the restricting groove 92.
In addition, in a state where the shift lever 10 is returned to the origin position (H) of the center guide groove 913, as described later with reference to fig. 10, the flat portion 822 and the protrusion 14 face each other with a predetermined gap therebetween. Therefore, even if the wheel 70 rotates clockwise on the XZ plane when viewed from the positive Y direction, the shift lever 10 does not move.
Fig. 9 and 10 show the shift switch device 1 in a state where the rotational position of the protruding portion 82 of the cam member 80 is the limit position. After the state is reached, the shift switch device 1 detects that the rotational position of the protruding portion 82 is at the limit position by the cam position detection hall ICs 33, 34, and stops the forward rotation of the motor 60 in accordance with the drive signal from the control portion AA. In this case, the flat portion 822 is opposed to the protrusion 14 with a predetermined gap therebetween, and the shift lever 10 is restricted from moving from the origin position (H) to the manual operation guide groove 911.
The operation of the shift switch device 1 when the parking switch is turned on in the state where the shift lever 10 is located at the neutral position (N) of the manual operation guide groove 911 has been described above with reference to fig. 5 to 10. When a predetermined operation to move the shift lever 10 to the forward position is detected, the shift switch device 1 rotates the motor 60 in reverse in accordance with the drive signal from the control unit AA, and the above-described operation described with reference to fig. 5 to 10 is performed in the reverse order to the above-described operation.
As described above, the shift switch device 1 includes the motor 60, the wheel 70 driven by the motor 60, and the cam member 80 moving in synchronization with the wheel 70. When the parking switch is detected to be turned on, and when it is detected that the shift lever 10 is located at the neutral position (N) of the manual operation guide groove 911, the motor 60 is rotated in the forward direction by the drive signal from the control unit AA, and the wheel 70 is rotated clockwise on the XZ plane as viewed from the positive Y direction. Then, the shift lever 10 is returned to the origin position (H) of the center guide groove 913 by moving the protrusion 82 from outside the operation path range of the shift lever 10 to inside the operation path range.
Therefore, by stopping the rotation of the wheel 70 after the shift lever 10 returns to the origin position (H) of the center guide groove 913, the protrusion 82 and the shift lever 10 can be opposed to each other in a state close to the shift lever 10. Therefore, it is possible to suppress the deviation of the lock position for shift-locking the shift lever 10 returned to the origin position (H) of the center guide groove 913.
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 parking switch is detected to be turned on, and when the shift lever 10 is detected to be located at the neutral position (N) of the manual operation guide groove 911, the shift switch device 1 rotates the motor 60 in the forward direction based on the drive signal from the control unit AA, thereby rotating the wheel 70 clockwise on the XZ plane as viewed from the positive Y direction. Then, the protrusion 82 is moved from outside the predetermined operation path range of the shift lever 10 to inside the predetermined operation path range, so that the shift lever 10 is returned to the origin position (H) of the center guide groove 913.
Therefore, by bringing the protrusion 82 into contact with the shift lever 10 positioned at the neutral position (N) of the manual operation guide groove 911 and pressing the shift lever 10 by the protrusion 82, the shift lever 10 can be returned from the neutral position (N) of the manual operation guide groove 911 to the origin position (H) of the center guide groove 913.
Further, the shift lever 10 of the shift switch device 1 is provided with a projection 14 projecting toward the neutral position (N) of the manual operation guide groove 911 at the origin position (H) of the center guide groove 913. The cam member 80 rotates on a plane intersecting the direction along the center guide groove 913, and the cam member 80 is provided with a pressing portion 821 and a flat portion 822 continuously formed from the pressing portion 821. Pressing part 821 abuts on projection 14 of shift lever 10 from the axial direction of shift lever 10, and flat part 822 is provided so as to be opposed to projection 14.
Therefore, by rotating the cam member 80, the protrusion 82 can be brought into contact with the protrusion 14 from the axial direction of the shift lever 10, and the shift lever 10 can be pressed by the protrusion 82.
Further, in the shift switch device 1, the flat portion 822 has a predetermined width in the rotational direction of the cam member 80.
Therefore, even if the cam member 80 is rotated in a state where the flat portion 822 and the protruding portion 14 of the shift lever 10 are opposed to each other, the flat portion 822 can be continuously opposed to the protruding portion 14, and the interval between the flat portion 822 and the protruding portion 14 can be maintained. Therefore, the presence or absence of inertial rotation and variations in the motor 60 can be absorbed by the flat surface portion 822, and variations in the lock position for shift-locking the shift lever 10 that returns to the origin position (H) of the center guide groove 913 can be suppressed.
In the shift switch device 1, the flat portion 822 is provided in parallel to the axial direction of the shift lever 10.
Therefore, even when the cam member 80 is rotated in a state where the flat portion 822 faces the protrusion 14 of the shift lever 10, the distance between the flat portion 822 and the protrusion 14 can be kept constant. Therefore, the presence or absence of inertial rotation and variations in the motor 60 can be absorbed by the flat surface portion 822, and variations in the lock position for shift-locking the shift lever 10 that returns to the origin position (H) of the center guide groove 913 can be further suppressed.
Further, in the shift switch device 1, one end of the pressing portion 821 in the rotation direction of the cam member 80 is connected to the flat portion 822. Further, the pressing portion 821 is inclined in a direction away from the shift lever 10 from one end to the other end of the pressing portion 821 in the rotation direction of the cam member 80.
Therefore, even in a state where pressing portion 821 is in contact with protruding portion 14, cam member 80 can be rotated by the inclination of pressing portion 821, and the portion in contact with protruding portion 14 can be changed from pressing portion 821 to flat portion 822.
Further, in the shift switch device 1, the cam member 80 is provided within the inner diameter of the wheel 70, and rotates integrally with the wheel 70 with the rotational shaft of the wheel 70 as the rotational center.
Therefore, since the wheel 70 and the cam member 80 can be rotated on the same plane, the space can be effectively utilized, and the shift switch device 1 can be miniaturized.
In the shift switch device 1, the hall ICs 33 and 34 for detecting the rotational position of the protruding portion 82 of the cam member 80 are mounted on the base plate 30 on which the hall ICs 31 and 32 for detecting the position of the shift lever 10 are mounted.
Therefore, the shift switch device 1 can be miniaturized.
In addition, according to the above-described embodiment, the wheel 70 rotates on a plane perpendicular to the Y direction, but is not limited to this, and may rotate on a plane intersecting the Y direction, in other words, a plane intersecting the direction along the center guide groove 913.
In the above-described embodiment, the cam member 80 and the wheel 70 are provided separately as described with reference to fig. 3, but the present invention is not limited thereto, and the cam member 80 and the wheel 70 may be provided integrally.
Further, according to the above-described embodiment, when the rotational position of the protruding portion 82 is at the restricting position, the flat portion 822 of the protruding portion 82 is disposed to face the protrusion portion 14 of the shift lever 10 with a predetermined gap. However, the present invention is not limited to this, and the flat surface 822 of the projection 82 may abut against the protrusion 14 of the shift lever 10 when the rotational position of the projection 82 is at the restricted position. In this way, the shift lever 10 returned to the origin position (H) of the center guide groove 913 can be prevented from being shaken.
