Description

  The present invention relates to a knob rotation position control device that selects a LOCK position, an ACC position, and the like by a series of operations based on knob pushing, rotation, and extraction force.

  Generally, in a handle lock device, a knob rotation position control device that selects a LOCK position, an ACC position, and the like by a series of operations based on pushing, rotating, and pulling force of a knob is used.

  As shown in FIG. 13A, the conventional knob rotation position control device 130 includes a knob-equipped rotor 133 and a rotor case 134.

  As shown in FIGS. 13A and 13B, the rotor with knob 133 is a member that selects a LOCK position, an ACC position, or the like by a series of operations based on pushing, rotating, and pulling force of the knob. , Knob portion 135, return spring 137, and projection 133a. The rotor body 132 is formed in a substantially cylindrical shape. The knob part 135 is formed in a knob shape and is disposed at one end of the rotor body 132 in the axial direction. The return spring 137 is disposed on the other end side in the axial direction of the rotor main body 132 via the camshaft 138 and the like, and is configured to resist pushing of the rotor main body 132 in the axial direction. The protrusion 133 a is formed on the side surface of the rotor main body 132. In general, the protrusion 133a is often a pin having a columnar shape or a rectangular column shape.

  Further, the rotor case 134 has a case main body 139 and a protrusion restricting hole 134a. The case main body 139 is formed in a cylindrical shape, and its inner diameter is formed substantially equal to the outer diameter of the rotor main body 132. The protrusion restricting hole 134a is provided so as to surround the protrusion 133a of the knob-attached rotor 133 inserted into the case main body 139, and at the right end of the substantially inverted U-shaped groove when viewed from the knob part 135 side. It is formed in a shape obtained by adding a horizontal groove. The protrusion restricting hole 134a has a rectangular base part 134b that extends to the other end side in the axial direction of the rotor main body 132 between the LOCK position and the ACC position of the protrusion 133a.

  In the conventional knob rotation position control device 130, even if the knob-attached rotor 133 is rotated without being pushed in, the protrusion 133 a of the knob-attached rotor 133 comes into contact with the rectangular base portion 134 b of the rotor case 134. That is, when it is desired to rotate the rotor with knob 133 in the direction from the LOCK position toward the ACC position (clockwise) or in the opposite direction (counterclockwise), the rotor with knob 133 is pushed in and the rotor with knob 133 is rotated. Rotating the knob-equipped rotor 133 after creating a state in which the protrusion 133a of the knob-equipped rotor 133 does not contact the rectangular base portion 134b of the rotor case 134 allows the LOCK position or the ACC position to be selected. The conventional knob rotation position control device 130 has been configured.

JP 2009-293389 A

  However, in the conventional knob rotation position control device 130, the knob-attached rotor 133 is pushed in and rotated in the middle of the rotation while rotating in the direction from the ACC position toward the LOCK position (counterclockwise) or in the opposite direction. When the operation is stopped and the extraction force operation is performed, the rotation of the knob-attached rotor 133 may stop at the position where the extraction force operation is performed. This is because the protrusion 133a of the knob-equipped rotor 133 continues to maintain a state where the protrusion 133a is in contact with the top surface of the rectangular base part 134b of the rotor case 134.

  At this time, in the vehicle equipped with the conventional knob rotation position control device 130, it is assumed that the supply of the ACC power is continued and the door cannot be locked due to the mechanism of the door lock device. If the door cannot be locked, the user of the vehicle will notice that a problem has occurred in the vehicle, but normally, if there is no warning sign such as an alarm, the user will notice that the problem is due to the operation of the rotor 133 with the knob. It is difficult.

  The slider 17 is formed on the side surface of the knob-equipped rotor 3 so as to be movable in the axial direction. The slider 17 is formed in a shape in which a rectangular parallelepiped having a rectangular shape in plan view is curved along the side surface of the knob-equipped rotor 3.

  Further, the slider 17 has an engagement convex portion 19 and an elastic member support portion 20. The engaging convex portion 19 has a shape in which a triangular prism is laid along the circumferential direction of the rotor 3 with the knob, and is engaged with the slider restricting groove 10 of the slider case 8. Further, the elastic member support portion 20 is formed in a columnar shape, and extends in parallel with the axial direction of the knob-equipped rotor 3 from the center of the end surface of the slider 17 on the knob portion 13 side.

  The slider 17 is also configured to have the function of the rectangular base part 134b of the conventional rotor case 2. Therefore, as shown in FIGS. 4 and 8, the width dimension of the slider 17 is set to be approximately the same as the distance from the LOCK position (see FIG. 4) to the ACC position (see FIG. 8) in the protrusion 15. Yes. Further, as shown in FIGS. 1, 3 and 4, 7 and 8, when the knob portion 13 of the knob-equipped rotor 3 is rotated without being pushed in, the projection portion 15 comes into contact with the slider 17. As shown in FIGS. 5 and 6, when the knob portion 13 of the knob-equipped rotor 3 is rotated while being pushed in, and then the extraction force is not operated, the shaft of the slider 17 is prevented from contacting the slider 17. The length and arrangement of directions are set.

  As shown in FIGS. 2 and 3, the second elastic member 18 is disposed between the end surface of the slider 17 on the knob portion 13 side and the inner surface of the slider case 8 on the knob portion 13 side. The second elastic member 18 is preferably a return spring such as a metal coil spring.

The force to insert acts. The second elastic member 18 resists the pushing force acting on the slider 17.

(Configuration of lever 5)
As shown in FIGS. 2 and 3, the lever 5 includes a lever main body 21, a rotating shaft 22, a first contact portion 23, and a second contact portion 24.

  The lever main body 21 is disposed in the vicinity of the side surface of the knob-equipped rotor 3 in parallel with the axial direction of the knob-equipped rotor 3 when the lever 5 is not operated. The lever body 21 is formed in a substantially quadrangular prism shape extending linearly in the axial direction of the knob-equipped rotor 3, and has a shaft hole 21a into which the rotating shaft 22 is inserted.

  The rotary shaft 22 is formed in a cylindrical shape extending from the side surface of the lever support portion 9 on the slider case 8 side in a direction orthogonal to the extending direction of the lever main body 21. When the rotating shaft 22 is inserted into the shaft hole 21 a of the lever body 21, it is preferable to attach a donut-shaped stopper 25 to the tip of the rotating shaft 22 in order to prevent the lever 5 from falling off.

  As shown in FIG. 3, the distance from the rotation shaft 22 to the other end 21c of the lever body 21 on the camshaft 16 side is 2 as the distance from the rotation shaft 22 to the one end 21b of the lever body 21 on the knob portion 13 side. It is preferable that it is set to be twice or more.

  As shown in FIGS. 2 and 3, the first abutment portion 23 is disposed on the knob-attached rotor 3 side at the end 21 b of the lever body 21 on the knob portion 13 side. The first contact portion 23 is formed in a substantially L shape and extends toward the camshaft 16 in the direction parallel to the axial direction of the rotor 3 with the knob.

  The first abutting portion 23 is provided at a position where it abuts against the slider 17 when the slider 17 slides toward the knob portion 13, and the rotating shaft 22 is centered when the abutting against the slider 17. Further, the lever body 21 is tilted by lifting the one end 21b on the knob section 13 side of the lever body 21 by the thickness of the slider 17. Therefore, it is preferable that the contact surface of the first contact portion 23 with the slider 17 is inclined by about 45 degrees so as to face the rotor 3 with knob. When the contact surface of the first contact portion 23 with the slider 17 is not inclined, the contact surface of the slider 17 with the first contact portion 23 is inclined by about 45 degrees so as to face the opposite side of the rotor 3 with the knob. It is preferable to make it.

  As shown in FIGS. 2 to 4, the second contact portion 24 is disposed on the rotor-with-knob 3 side at the other end 21 c of the lever body 21 on the camshaft 16 side. The second contact portion 24 is preferably formed in a substantially L shape and extends along the circumferential direction of the rotor 3 with the knob. In this case, as shown in FIG. 4, the inner angle of the substantially L-shaped second abutting portion 24 is 90 degrees or more and is directed from the ACC position side (left side in FIG. 4) to the LOCK position side (right side in FIG. 4). Thus, it is preferable that the second contact portion 24 is set at an angle that moves away from the rotor 3 with the knob.

  Further, as shown in FIG. 4, the second contact portion 24 is configured to have the same width as the slider 17. The second abutment portion 24 presses the top portion 15a of the projection 15 against the rotor 3 with knob when the lever main body 21 is inclined as described above. As shown in FIG. 4, the slider 17 is disposed in the vicinity of the upper end of the slider 17 that contacts the protrusion 15. The arrangement of the second contact portion 24 may be above the end of the slider 17 that makes contact with the protruding portion 15, or may be a position closer to the camshaft 16 than the position thereof.

[Rotation position operation by knob rotation position control device 1]
Next, the rotational position operation by the knob rotational position control device 1 will be described with reference to FIGS. 3 to 12. Here, FIG. 9 is a partial front view showing a state in which the knob 15 is operated to pull out the knob 15 at a position close to the ACC position in the knob rotation position control device 1 according to the embodiment of the present invention. FIG. 10 is a side view of FIG. 9 viewed from the opposite side of the knob portion 13. FIG. 11 is a partial front view showing a state in which the knob 15 is operated with a pulling force at a position near the LOCK position in the knob rotation position control apparatus 1 according to the embodiment of the present invention. FIG. 12 is a side view of FIG. 11 viewed from the opposite side of the knob portion 13.

(Normal operation)
First, as shown in FIGS. 3 and 4, in the LOCK state, the protrusion 15 of the knob-equipped rotor 3 is disposed between the protrusion restricting hole 7 and the slider 17. The slider 17 is disposed on the camshaft 16 side by the urging force of the second elastic member 18. The lever 5 is not yet tilted and maintains a state of being arranged in parallel to the axial direction of the knob-equipped rotor 3.

  Next, when shifting from the LOCK state to the ACC position, first, the knob portion 13 of the knob-equipped rotor 3 is pushed, and the protruding portion 15 moves to the camshaft 16 side. In this state, when the knob-equipped rotor 3 is rotated clockwise (counterclockwise in FIG. 4), the protrusion 15 does not come into contact with the slider 17 as shown in FIGS. It passes the camshaft 16 side clockwise (counterclockwise in FIG. 4). At this time, the slider 17 is not pushed into the protrusion 15 and maintains the state of being arranged on the camshaft 16 side by the urging force of the second elastic member 18. Similarly, the lever 5 does not tilt and maintains a state of being arranged in parallel to the axial direction of the knob-equipped rotor 3.

  Next, when the projection 15 has finished moving to the position where it has moved to the camshaft 16 side relative to the ACC position, the rotation operation of the knob portion 13 is terminated, and the operation moves to the extraction force operation. In this state, as shown in FIGS. 7 and 8, the protrusion 15 does not contact the end of the slider 17 on the camshaft 16 side, and moves to the right side of the slider 17 when viewed from the knob portion 13. . Similarly to the above, the slider 17 is not pushed into the protrusion 15 and maintains the state of being arranged on the camshaft 16 side by the urging force of the second elastic member 18. Similarly, the lever 5 does not tilt and maintains a state of being arranged in parallel to the axial direction of the knob-equipped rotor 3.

  The same applies to the counterclockwise (clockwise in FIG. 4) rotation operation of the knob-equipped rotor 3 that shifts from the ACC position to the LOCK state.

(Position control when operation is interrupted)
Next, let us consider a state in which a pulling force operation is performed on the knob portion 13 of the rotor 3 with the knob unlike the normal operation when shifting from the LOCK state to the ACC position or vice versa.

  As shown in FIGS. 9 and 10, when the pulling operation is performed on the knob portion 13 during the rotation of the rotor 3 with the knob, the rotor 3 with the knob is moved from the camshaft 16 side by the biasing force of the first elastic member 14. It moves to the part 13 side, and the projection part 15 also moves in the same direction in connection with it. As a result, the projection 15 abuts against the end of the slider 17 on the camshaft 16 side, and the pushing force of the projection 15 overcomes the elastic force of the second elastic member 18, so that the slider 17 is pushed into the knob portion 13. Rarely, it tries to move to the knob 13 side.

  When the slider 17 is pushed into the protrusion 15, the first contact portion 23 of the lever 5 contacts the end of the slider 17 on the knob portion 13 side, and the end 21 b on the knob side of the lever 5 is lifted, whereby the lever 5 tilts. As a result, the other end 21c of the lever 5 on the camshaft 16 side is lowered, and the second contact portion 24 moves in a direction approaching the rotor 3 with knob, so that the top portion 15a of the protrusion 15 is the second contact portion 24. It will be pressed.

  In the above state, the second contact portion 24 is pressed against the right side portion (side portion on the ACC position side) of the top portion 15a of the projection portion 15 when viewed from the knob portion 13 side. Therefore, as shown in FIGS. 9 and 10 to 11 and 12, the protrusion 15 is counterclockwise as viewed from the knob portion 13 due to the pushing force of the second contact portion 24 (in FIG. 10 and FIG. Forcibly (rotate). Since the projection 15 is formed on the rotor 3 with the knob, the rotor 3 with the knob is similarly counterclockwise as viewed from the knob 13 by the forced movement of the projection 15 (clockwise in FIGS. 10 and 12). It is forcibly rotated (moved). This forced rotation is maintained as long as the protrusion 15 pushes the slider 17.

  When the protruding portion 15 moves to the left of the left side portion (side portion on the LOCK position side) of the slider 17 when viewed from the knob portion 13 side, the contact relationship between the protruding portion 15 and the slider 17 ends, and the protruding portion The force with which the portion 15 pushes the slider 17 disappears. As a result, the slider 17 returns to the state where it is again arranged on the camshaft 16 side by the urging force of the second elastic member 18. When the slider 17 moves to the camshaft 16 side, the second contact portion 24 is pushed to the camshaft 16 side, so that the other end 21c of the lever 5 on the camshaft 16 side is lifted. The state returns to the state of being arranged parallel to the axial direction of the attached rotor 3.

  With the above operation, the knob-equipped rotor 3 having the protrusion 15 automatically returns to the LOCK position as shown in FIGS.

[Effect of the embodiment]
According to the embodiment of the present invention, the following effects can be obtained.

  (1) In the knob rotation position control device 1 according to the embodiment of the present invention, the slider 17 is slid to the knob portion 13 side by pushing the projection portion 15, and the lever 5 is It is the structure which presses the top part 15a. Thereby, since the projection part 15 is forcibly moved to the LOCK position or the ACC position, the rotor 3 with the knob can be surely automatically returned to the LOCK position or the ACC position.

  (2) As described above, the lever main body 21 of the lever 5 is provided with the first contact portion 23 that contacts the slider 17 and the second contact portion 24 that contacts the projection portion 15, so that the lever around the rotation shaft 22 is provided. The shaft 5 can be rotated. Thereby, the forcible movement of the protrusion 15 can be quickly performed according to the movement of the slider 17.

  (3) As described above, the distance from the rotary shaft 22 to the other end 21c in the lever main body 21 is set to be twice or more the distance from the rotary shaft 22 to the one end 21b. Accordingly, the lever 5 pushes down the protrusion 15 when the protrusion 15 pushes the slider 17 more than twice, so that the protrusion 15 can be easily forcibly moved.

  (4) As described above, in the rotor case 2, the movement of the protrusion restriction hole 7 that restricts the movement of the protrusion 15 only within a predetermined region and the movement of the slider 17 are limited only to the axial translation of the rotor 3 with the knob. A slider case 8 is provided. Thereby, since the projection 15 and the slider 17 can be prevented from moving unintentionally, the knob-equipped rotor 3 can be surely automatically returned to the LOCK position or the ACC position.

  The embodiment of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, it is possible to change from the automatic return mechanism to the LOCK position to the automatic return mechanism to the ACC position by reversing the inclination of the top surface of the protrusion 15 and the second contact portion 24 from the present embodiment. .
