DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, a vehicle shift lever device (hereinafter referred to as a shift lever device) 10 according to an embodiment of the present invention has a shift lever 30 in a vehicle front-rear direction (hereinafter referred to as a shift direction), a vehicle left-right direction (hereinafter referred to as a select) The shift lever device can be moved in a direction) and is provided with shift positions such as P (parking) 90a, R (reverse) 90b, N (neutral) 90c, and D (drive) 90d. However, the shift lever device 10 is not limited to the four positions of P, R, N, and D, and is further provided with positions such as 3 (third) 90e, 2 (second) 90f, and L (low) 90g. It may be a lever device (in the illustrated example, 3, 2, and L are shown).
[0007]
The shift lever device 10 includes a groove 20, a shift lever 30, a lever boss 40, a rotating member 50, a spring 60, and a stopper 70. However, the lever boss 40 is not essential.
[0008]
As shown in FIG. 2, the groove 20 is formed in a base plate 80 fixedly attached to the vehicle or a housing 81 fixedly attached to the base plate 80. Inside the base plate 80, a shaft 82 supported by the base plate 80 so as to be rotatable in the vehicle front-rear direction is provided. The shaft 82 is made of metal or resin.
The groove 20 restricts the movement range of the shift lever 30. As shown in FIG. 1, an impact absorbing material 21 is attached to the edge of the groove 20. The impact absorbing material 21 is elastically deformed and suppresses the occurrence of contact hitting sound between the edge of the groove 20 and the shift lever 30.
[0009]
The groove 20 is provided with at least one crank portion 22. Here, the crank portion 22 includes not only a crank shape but also a bent shape and a branched shape. The crank portion 22 is, for example, between the D position 90d and the R position 90b. However, the crank portion 22 is not limited to the position between the D position 90d and the R position 90b, and may be, for example, between the 2 position 90f and the L position 90g.
[0010]
The shift lever 30 is made of metal. As shown in FIG. 2, the shift lever 30 extends in the vertical direction. The shift lever 30 has a lever support portion 31 at the bottom. The lever support portion 31 is made of resin. The lower end portion of the lever support portion 31 is supported on the shaft 82 so as to be swingable in the vehicle left-right direction. The shift lever 30 is configured such that the shaft 82 can rotate in the vehicle front-rear direction with respect to the base plate 80, and the lever support portion 31 can swing in the vehicle left-right direction with respect to the shaft 82. The vehicle can be swung back and forth and left and right.
The shift lever 30 moves with a play S in the groove 20 as shown in FIG.
[0011]
The lever boss 40 is made of resin, for example. The lever boss 40 is formed integrally with the lever support portion 31, or formed separately from the lever support portion 31 and fixedly attached to the lever support portion 31. The lever boss 40 protrudes from the shift lever 30 in a direction orthogonal to or substantially orthogonal to the longitudinal direction of the shift lever 30 (for example, the vehicle left direction). The connecting portion between the front end surface 40a in the protruding direction of the lever boss 40 and the vehicle rear side surface 40b of the lever boss 40 is a corner.
[0012]
The rotating member 50 is made of resin, for example. When the shift lever 30 at the D position 90d is shift-changed to the N position 90c, the rotating member 50 prevents the N position 90c from jumping over and entering the R position 90b beyond that due to the oblique shift. Is provided. However, the rotating member 50 not only prevents erroneous operation at the R position 90b, but also, for example, when the shift lever 30 at the 3 position 90e is shift-changed to the 2 position 90f, the turning member 50 jumps over the 2 position 90f by an oblique shift. It may be provided in order to prevent entering the previous L position 90g.
The rotating member 50 is rotatably supported by the base plate 80 or the housing 81. The rotation shaft of the rotation member 50 extends, for example, in the vertical direction.
The rotation member 50 includes a rotation shaft portion 51, a lever contact portion 52, and a stopper contact portion 53.
[0013]
The lever contact portion 52 can come into contact with the shift lever 30 or the lever boss 40 (in the illustrated example, the case where it can come into contact with the lever boss 40 is shown). In the embodiment of the present invention, a case where the lever contact portion 52 can come into contact with the lever boss 40 is shown.
The lever contact portion 52 extends in a direction orthogonal or substantially orthogonal to the vertical direction. The lever contact portion 52 extends from the rotating shaft portion 51 in a direction approaching the lever boss 40. The shape of the front end surface 52a in the extending direction of the lever contact portion 52 is parallel to the locus of movement of the front end surface 40a in the protruding direction of the lever boss 40 when the shift lever 30 is shifted from the D position 90d toward the N position 90c. . The shape of the vehicle front side surface 52b of the lever contact portion 52 is parallel to the locus of movement of the vehicle rear side surface 40b of the lever boss 40 when the shift lever 30 is selected at the N position 90c. The extending direction front end surface 52 a of the lever contact portion 52 is orthogonal to the vehicle front side surface 52 b of the lever contact portion 52. The vehicle front side end of the front end surface 52a in the extending direction of the lever contact portion 52 is continuous with one end of the vehicle front side surface 52b of the lever contact portion 52. A portion where the front end surface 52a in the extending direction of the lever contact portion 52 and the vehicle front side surface 52b are connected is a corner 54.
[0014]
At least the corner 54 of the lever contact portion 52 can enter and exit the movement range of the lever boss 40. The positional relationship between the movement range of the lever contact portion 52 and the lever boss 40 is as follows. (1) When the shift lever 30 moves on the crank portion 22, (1) When the shift lever 30 moves on the crank trajectory A, 52, the lever boss 40 and the lever contact portion 52 are set to hit when the shift lever 30 moves away from the crank locus A.
[0015]
The stopper contact portion 53 extends from the rotation shaft portion 51 in a direction (front of the vehicle) different from the extending direction of the lever contact portion 52 in a direction orthogonal or substantially orthogonal to the vertical direction. The stopper contact portion 53 can contact the stopper 70. However, a cushioning material may be interposed between the stopper contact portion 53 and the stopper 70 in order to suppress the hitting sound. The surface 53a on the lever boss 40 side of the stopper contact portion 53 is parallel or substantially parallel to the front end surface 52a in the extending direction of the lever contact portion 52. The vehicle rear side end of the surface 53a of the stopper abutting portion 53 is opposite to the other end of the vehicle front side surface 52b of the lever contact portion 52 (of the vehicle front side surface 52b, the side continuous with the front end surface 52a in the extending direction of the lever contact portion 52). Side end).
[0016]
The spring 60 is made of, for example, a torsion spring. The spring 60 always urges the rotation member 50 in a direction in which the stopper contact portion 53 of the rotation member 50 contacts the stopper 70. The direction in which the spring 60 biases the rotating member 50 is when the shift lever 30 at the D position 90d is shifted to the R position 90b, and the lever boss 40 hits the corner 54 of the lever contact portion 52 of the rotating member 50. In this case, the lever boss 40 presses the lever contact portion 52 and is in the same direction as the direction in which the rotating member 50 is to be rotated.
[0017]
The stopper 70 is formed integrally or separately with the base plate 80 or the housing 81. The stopper 70 restricts the rotation end of the rotation member 50 in the spring 60 biasing direction. The stopper 70 comes into contact with the stopper contact portion 53 of the rotating member 50 when the rotating member 50 is positioned at the rotating end in the spring 60 biasing direction.
[0018]
Next, the operation of the embodiment of the present invention will be described.
When the shift lever 30 is positioned at the D position 90d, the lever boss 40 is not in contact with the rotating member 50. The protruding end surface 40a of the lever boss 40 is opposed to the extending end surface 52a of the lever contact portion 52 of the rotating member 50. In the rotating member 50, the stopper contact portion 53 is in contact with the stopper 70 by the biasing force of the spring 60.
[0019]
The case where the shift lever 30 moves the crank portion 22 from the D position 90d to the R position 90b will be described.
(1) When the shift lever 30 moves on the crank locus A, the lever boss 40 and the lever contact portion 52 do not hit each other. The stopper contact portion 53 of the rotating member 50 continues to contact the stopper 70.
(2) When the shift lever 30 moves away from the crank locus A, the lever boss 40 hits the corner 54 (extension end surface 52a) of the lever contact portion 52, and the lever contact portion 52 is in the same direction as the spring 60 biasing direction. Push in the direction. Although the lever contact portion 52 is pushed by the lever boss 40, the rotating member 50 does not rotate because the stopper contact portion 53 is in contact with the stopper 70. Therefore, the movement of the shift lever 30 is restricted on the crank locus A.
[0020]
When the shift lever 30 is positioned at the R position 90b, the lever boss 40 is not in contact with the rotating member 50. The vehicle rear side surface 40 b of the lever boss 40 faces the vehicle front side surface 52 b of the lever contact portion 52 of the rotating member 50. The stopper contact portion 53 of the rotating member 50 is in contact with the stopper 70 by the biasing force of the spring 60.
[0021]
The case where the shift lever 30 moves the crank portion 22 from the R position 90b to the D position 90d will be described.
(1) When the shift lever 30 moves on the crank locus A, the lever boss 40 and the lever contact portion 52 do not hit each other. The stopper contact portion 53 of the rotating member 50 continues to contact the stopper 70.
(2) When the shift lever 30 moves away from the crank locus A, the vehicle rear side surface 40b of the lever boss 40 hits the corner 54 (vehicle front side surface 52b) of the lever contact portion 52, and the lever contact portion 52 is brought into contact with the spring 60. Push in the direction opposite to the biasing direction. The rotating member 50 rotates in the direction opposite to the biasing direction of the spring 60. Therefore, the movement of the shift lever 30 on the locus deviating from the crank locus A is possible.
[0022]
Next, the operation of the embodiment of the present invention will be described.
A rotating member 50 is provided so that the lever contact portion 52 enters and leaves the movement range of the lever boss 40. For this reason, (1) when the shift lever 30 is moved from the D position 90d to the R position 90b, if the shift lever 30 deviates from the crank locus A, the lever boss 40 hits the rotating member 50 and the shift lever 30 moves to the crank locus A. (2) When the shift lever 30 is moved from the R position 90b to the D position 90d, the lever boss 40 pushes the rotating member 50 when the shift lever 30 moves out of the crank trajectory A. 50 rotates and the shift lever 30 can be moved out of the crank locus A (the crank locus is not forced). Therefore, operability is improved.
[0023]
【The invention's effect】
According to the shift lever device for a vehicle according to claim 1 Symbol placement, the rotating member is provided which is provided as part per lever is out of the range of movement of the shift lever. For this reason, the rotation member hits the rotation member in one direction and moves on the crank locus, but the rotation member rotates in the other direction and can move away from the crank locus (the crank locus is not forced). Therefore, operability is improved.
