[0007]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. 1 and 2 show an embodiment of an operating device for an automatic transmission according to the present invention.
The operating device 10 according to this embodiment includes a shift lever 11 and an operating knob 12 provided on the upper portion thereof, like the operating device for an automatic transmission arranged in the center console. A lower portion of the shift lever 11 is rotatably supported by a detent plate 14 or the like fixed to an instrument panel 13, and a wire 15 connected to an automatic transmission (not shown) is coupled to a lower end portion thereof. . A shift lock release shaft 16 is arranged in the shift lever 11, and an umbrella-shaped shift lever upper gear 17 which constitutes a second rotation transmission mechanism is attached to an upper portion thereof. The upper end of the shift lock release shaft 16 is in contact with the tip of a shift lock release button 18 arranged in the operation knob 12. A shift lever lower gear 19 which constitutes a first rotation transmission mechanism is fixed to a lower portion of the shift lock releasing shaft 16 and meshes with a plate gear 20 fixed to the detent plate 14. A detent holding portion 22 biased by a spring 21 is arranged on the lower surface of the shift lock releasing shaft 16. Detent holder 2
A pin 23 projects outward from 2 and engages with a gear groove 24 formed in the detent plate 14 at a predetermined position.

On the other hand, inside the operation knob 12, the exterior cover 25 of the shift lock release button 18 is fixed integrally with the casing 26 of the operation knob 12.
An umbrella-shaped operation knob gear 27 is fixed to the tip of the exterior cover 25, and the rotation of the operation knob gear 27 causes the casing 26 of the operation knob 12 to rotate together. The operation knob gear 27 meshes with the shift lever upper gear 17 in a direction orthogonal to the shift lever upper gear 17.

Next, the operation of the operating device 10 having the above structure will be described. First, when the driver holds the operation knob 12 and presses the shift lock release button 18, the shift lock release shaft 16 is pushed down accordingly, and the pin 23 is pushed down together with the detent holding portion 22. The pin 23 is locked in a gear groove 24 provided in the detent plate 14, and when the shift lock release button 18 is pressed, the lock is released and the shift lever 11 can be freely moved.

As shown in FIG. 2, the position of the shift lever 11 is set to P (parking), R (reverse), N.
In the four positions of (neutral) and D (drive), when the driver pushes or pulls the operation knob 12 to move the shift lever 11 to another position, the plate lever 20 moves above the shift lever lower gear 19. Since they rotate while meshing with each other, the rotation is transmitted to the shift lock release shaft 16 accordingly. As the shift lock release shaft 16 rotates, the shift lever upper gear 17 also rotates, and the rotation of the operation knob gear 27 meshing with the shift lever upper gear 17 is transmitted. Since the operation knob gear 27 uses the exterior cover 25 as a rotation axis, when the operation knob gear 27 rotates, the operation knob 12 is rotated.
The casing 26 of is also rotated together. That is, the shift lock release shaft 16 rotates according to the stroke amount when the shift lever 11 changes its position, and the operation knob 12 rotates in conjunction with it.

Therefore, as shown in FIG. 3, even when the position of the shift lever 11 is moved from the position P farthest from the position of the driver 7 to the position D closest to the position of the driver 7, the operation knob 12 is moved according to the stroke amount. Rotates,
Since the angle with respect to the shift lever 11 changes, P
The angle θ3 between the operating knob 12 and the wrist at the position and the angle θ4 when the operating knob 12 is pulled toward you and moved to the D position are approximately θ3 = θ4, and the wrist angle is kept constant. The wrist is not as tight as it used to be.

FIG. 4 shows an angle θ5 between the shift lever 11 and the operation knob 12 with respect to the stroke amount of the shift lever 11.
The relationship between (angles shown in FIG. 3) is shown, and the relationship between the two is a negative proportional straight line. That is, in this embodiment, the angle θ5 is gradually reduced as the stroke amount of the shift lever 11 increases, so that the wrist angle is always constant. By the way, the broken line shows the relationship between the two in the conventional example.Since the shift lever and the operation knob are fixed integrally, the angle of the operation knob remains unchanged even if the position of the shift lever changes. It is always constant.

FIG. 5 shows another embodiment of the present invention, in which the operation knob 12 is rotatably supported with respect to the shift lever 11 with the outer cover 25 of the shift lock release button 18 as a shaft. It is a thing. Further, a lock pin 31 that is biased by a spring 30 is provided on the exterior cover 25 side,
The lock pin 31 is engaged with a pin engagement member 32 provided on the inner peripheral surface of the operation knob 12 side. Pin engaging member 32
Is the gear groove 2 at each position of the detent plate 14.
4 is formed with a concave groove 33, and the lock pin 31 biased by the spring 30 is always engaged.

Therefore, although the lock lever 31 is normally engaged with the lock pin 31 to lock the shift lever 11 and the operation knob 12, the driver pushes the shift lock release button 18 to shift the shift lever 11. Is released and, for example, when the shift lever 11 is moved from the P position to the D position and at the same time a rotational force of a certain amount or more is applied to the operation knob 12, the lock pin 31 overcomes the concave grooves 33 one by one, and the operation knob 12 Rotates. At that time, shift lever 1
By engaging the lock pin 31 with the recessed groove 33 corresponding to the position of the gear groove 24 with which 1 is engaged, the operation knob 12 can be locked while being kept horizontal. As described above, in this embodiment, the angle of the wrist can be freely changed corresponding to the position of the shift lever 11 as described above, and an operation with a click feeling can be performed.

[0015]

As described above, according to the automatic transmission operating device of the present invention, the rotation angle of the operating knob is set according to the stroke amount when the position of the shift lever is changed. In any position, the wrist angle can always be kept constant, and the shift operation can be performed at a comfortable wrist angle.
