Description

  The present invention relates to a shift lock device that regulates shift change of a shift lever by regulating movement of a detent pin in a detent groove.

  Japanese Patent Application Laid-Open No. 6-313472 discloses a shift lock device that restricts the shift change of the shift lever by restricting movement of the detent pin within the detent groove. In the shift lock device disclosed in the above publication, even if the detent pin is moved downward by pushing the shift knob button, the movement is restricted by contacting a lock lever that is rotatably attached to the base.

However, the conventional shift lock device has the following problems.
Since the lock lever is rotatably attached to the base, the force from the detent pin is applied to the rotation shaft portion of the lock lever. Therefore, a thickness (strength) that can withstand the force from the detent pin is required for the pivot shaft portion of the lock lever. For this reason, the rotation shaft portion of the lock lever is increased in size and weight.

1 to 6 show a shift lock device according to an embodiment of the present invention and a shift lever device provided with the shift lock device.
First, the shift lever device 1 provided with the shift lock device 10 of the embodiment of the present invention will be described.

The shift lever device 1 may be disposed on an instrument panel portion that is an interior member of the vehicle, or may be disposed on the floor of the vehicle. The shift lever device 1 is a straight type shift lever device.
As shown in FIG. 1, the shift lever device 1 includes a detent plate 2 provided with a detent groove 2 a, a shift lever 3, and a detent pin 4.

  The detent plate 2 is fixed with respect to the vehicle. A shaft 2 c constituting a rotation shaft of the shift lever 3 is attached to the detent plate 2 or a member fixed to the detent plate 2. The detent groove 2 a is a hole provided in the detent plate 2.

The shift lever 3 is rotatably supported by the detent plate 2 or a member fixed to the plate 2 via the shaft 2c. A knob (not shown) is attached to the upper end of the shift lever 3. The knob is provided with a shift knob button (not shown) that moves the detent pin 4 to the lower end side of the shift lever 3.
The shift lever 3 can take a first shift position 3a and a second shift position 3b, which are adjacent shift positions. Here, the first shift position 3a is, for example, an N (neutral) position, and the second shift position 3b is, for example, R (reverse). However, the first shift position 3a may be the P (parking) position and the second shift position 3b may be the R position (in the illustrated example, the first shift position 3a is the N position and the second shift position). The case where the position 3b is the R position is shown).

The detent pin 4 is supported by the shift lever 3 so as to be movable in the axial direction of the shift lever 3. The detent pin 4 extends in a direction orthogonal to the axial direction of the shift lever 3. The detent pin 4 enters the detent groove 2a. The detent pin 4 is always urged upward with respect to the shift lever 3 by a pin urging spring (not shown).
The detent pin 4 is positioned at the first shift position corresponding position 4a in the detent groove 2a when the shift lever 3 is at the first shift position 3a, and when the shift lever 3 is at the second shift position 3b. It is located at the second shift position corresponding position 4b in the detent groove 2a.

Here, the operation when the detent pin 4 is moved from the first shift position corresponding position 4a to the second shift position corresponding position 4b will be described.
When the shift lever 3 is in the first shift position 3a and the detent pin 4 is in the first shift position corresponding position 4a, the shift knob button (not shown) is operated to move the detent pin 4 to the pin bias spring (not shown). Push down against the urging force of. Thereafter, the shift lever 3 is moved from the first shift position 3a to the second shift position 3b while the detent pin 4 is pushed down. After the shift lever 3 reaches the second shift position 3b, the operation of the shift knob button is released, whereby the detent pin 4 is raised by the biasing force of the pin biasing spring and reaches the second shift position corresponding position 4b.

Next, the shift lock device 10 of the embodiment of the present invention will be described.
The shift lock device 10 of the embodiment of the present invention regulates the shift lever 3 by restricting the detent pin 4 from moving from the first shift position corresponding position 4a to the second shift position corresponding position 4b in the detent groove 2a. Is a shift lock device that restricts movement from the first shift position 3a to the second shift position 3b.

The shift lock device 10 includes a link 20, an urging spring 30, and an electromagnet (which may be a solenoid) 40.
The link 20 is made of resin. The link 20 includes a rotation shaft portion 21, a stopper portion 22, and a connecting portion 23 that connects the rotation shaft portion 21 and the stopper portion 22.

  The rotation shaft portion 21 is rotatably supported by the detent plate 2 or a member fixed to the plate 2. Since the rotation shaft portion 21 is rotatably supported by the detent plate 2 or a member fixed to the plate 2, the link 20 rotates to the detent plate 2 or a member fixed to the plate 2. It is supported movably. The rotation axis of the link 20 is orthogonal to the rotation axis of the shift lever 3. The rotating shaft portion 21 is integrally provided with a contact portion 21 a that contacts the flange portion 42 a of the plunger 42 of the electromagnet 40.

  The stopper portion 22 has a block shape. The stopper portion 22 can be moved in and out of the detent groove 2 a when the link 20 rotates around the rotation axis of the link 20. Since the stopper portion 22 can enter and exit the detent groove 2a, when the stopper portion 22 enters the detent groove 2a, the stopper portion 22 and the edge 2b (detent plate 2) of the detent groove 2a (see FIG. 6) There is a slight gap between them.

  When the stopper portion 22 enters the detent groove 2a, the stopper portion 22 enters the movement locus of the detent pin 4 that moves from the first shift position corresponding position 4a to the second shift position corresponding position 4b. . The stopper portion 22 is bent when the stopper portion 22 enters the detent groove 3a and the detent pin 4 moves from the first shift position corresponding position 4a to the second shift position corresponding position 4b. It moves by being pushed by the detent pin 4 and contacts the edge 2b (see FIG. 6) of the detent groove 2a. As shown in FIG. 2, the stopper portion 22 abuts against the detent pin 4 at the abutment surface 22a, on the edge 2b of the detent groove 2a and the stopper surface 22b located on the opposite side (back side) of the abutment surface 22a. Abut.

  The connecting portion 23 has a rod shape extending from the rotating shaft portion 21 to the stopper portion 22. The connecting portion 23 can be bent using the resin elasticity only in a direction parallel to the rotation axis of the link 20 (can be elastically deformed). Since the connecting portion 23 can be bent using resin elasticity, when the stopper portion 22 has entered the detent groove 2a and is pressed by the detent pin 4, the connecting portion 23 has an edge of the detent groove 2a. It is allowed to move in the direction approaching 2b.

  The biasing spring 30 is, for example, a torsion spring. One end of the urging spring 30 is applied to the detent plate 2 or a member fixed to the plate 2, and the other end of the urging spring 30 is applied to the rotating shaft portion 21. The urging spring 30 constantly urges the link 20 to rotate in the direction in which the stopper portion 22 exits the detent groove 2a.

The electromagnet 40 includes a main body 41 and a plunger 42 that can move forward and backward with respect to the main body 41.
The main body 41 is fixed to the detent plate 3 or a member fixed to the plate 3.
When energized, the plunger 42 moves in a direction to enter the main end 41 with respect to the main body 41. The plunger 42 includes a flange portion 42 a that contacts the contact portion 21 a of the rotation shaft portion 21.
When the electromagnet 40 is energized, it moves in a direction in which the flange portion 42 a enters the main body portion 41 and pushes the contact portion 21 a of the rotating shaft portion 21, thereby resisting the link 20 against the biasing force of the biasing spring 30. Then, the stopper portion 22 is rotated in a direction to enter the detent groove 2a.

Here, the operation of the embodiment of the present invention will be described.
(I) When the electromagnet 40 is not energized and the stopper portion 22 does not enter the detent groove 2 a The stopper portion 22 does not enter the movement locus of the detent pin 4. Therefore, the detent pin 4 can move from the first shift position corresponding position 4a to the second shift position corresponding position 4b. Therefore, the shift lever 3 can be moved from the first shift position 3a to the second shift position 3b.

(Ii) When the electromagnet 40 is energized and the stopper portion 22 enters the detent groove 2a (in the shift lock state)
The stopper portion 22 enters the movement locus of the detent pin 4. Therefore, when the shift lever 3 is moved from the first shift position 3a to the second shift position 3b with the detent pin 4 pushed down by operating a shift knob button (not shown), the detent pin 4 contacts the stopper portion 22. It contacts the contact surface 22a. When the shift lever 3 is further moved to the second shift position 3 b side, the stopper portion 22 is pushed by the detent pin 4. When the stopper portion 22 is pushed by the detent pin 4, the connecting portion 23 bends, and the stopper portion 22 moves in the detent groove 2a until the stopper surface 22b contacts the edge 2b of the detent groove 2a. When the stopper portion 22 is pushed by the detent pin 4 and the stopper surface 22b comes into contact with the edge 2b (when the stopper portion 22 is sandwiched between the detent pin 4 and the edge 2b), the second shift position beyond that of the detent pin 4 Movement to the corresponding position 4b side becomes impossible. Therefore, the movement of the shift lever 3 from the first shift position 3a to the second shift position 3b is locked.

Next, the operation of the embodiment of the present invention will be described.
In the embodiment of the present invention, the stopper portion 22 is pushed and moved by the detent pin 4 as the connecting portion 23 bends, and comes into contact with the edge 2b of the detent groove 2a. Therefore, the stopper portion 22 is sandwiched between the detent pin 4 and the edge 2b of the detent groove 2a to restrict the detent pin 4 from moving from the first shift position corresponding position 4a to the second shift position corresponding position 4b. Can do. Therefore, the force from the detent pin 4 can be received by the detent plate 2, and the force from the detent pin 4 can be prevented from being applied to the rotation shaft portion 21 of the link 20. As a result, the rotation shaft portion 21 (the rotation shaft portion of the member that restricts the movement of the detent pin) can be reduced in size and weight compared to the conventional case.
Further, the detent plate 2 originally has a strength that can withstand the force of the arm that operates the shift lever 3, and receives the force from the detent pin 4 by the plate 2, so that the shift lock mechanism portion (rotating shaft portion) 21 and the electromagnet 40) need not be designed in consideration of the shift lock strength.

  In addition, the biasing spring 30 that pivotally biases the link 20 in a direction in which the stopper portion 22 exits the detent groove 2a, and the stopper portion 22 resists the biasing force of the biasing spring 30 when energized. Since it has the electromagnet 40 which rotates the link 20 in the direction to enter, the stopper part 22 can be made to go in and out of the detent groove | channel 2a with a simple structure.
