Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shift lever device for performing shift control of an automatic transmission (automatic transmission) of an automobile, and particularly to a floor type shift lever device.

[0002]

[Prior Art]

 The floor-type shift lever device for an automatic transmission has a shift lever that protrudes above the floor.For example, in a cab-over type automobile, when the vehicle is stopped or parked, the occupant moves between the driver's seat and the passenger's seat. The shift lever gets in the way when you lie down or lie on the seat.

In order to deal with such a problem, a foldable shift lever such as the floor shift lever found in Japanese Utility Model Laid-Open No. 61-204217 has been proposed. In this prior art, the shift lever main body is divided into an upper part and a lower part, and an outer cylinder is provided outside the shift lever main body. Under normal conditions (when the shift lever is used), this outer cylinder covers the connecting portion between the upper part and the lower part of the shift lever body, and the upper part and the lower part are fixed by this outer cylinder. When folding the shift lever, move the shift lever to the P range, that is, the parking range, and pull the outer cylinder together with the shift operation knob by hand to expose the above-mentioned connecting portion. To be able to fold.

[0004]

[Problems to be solved by the device]

 In the case of the above-described prior art, in the P range, the shift lever itself can be moved upwards unconditionally and can be folded, which is not only a safety issue but also a cause of instability of the shift lever. Become. In addition, in a normal floor-type shift lever device, the shift lever leans forward in the P range to the side farthest from the driver, so pulling the operation knob together with the outer cylinder in the P range leaves the seat still seated. It is difficult to do it in this posture.

Therefore, an object of the present invention is to provide a shift lever device in which the tilting operation of the shift lever can be performed reliably and easily by an operation part different from the shift lever, and sufficient safety is ensured. Especially.

[0006]

[Means for Solving the Problems]

 The shift lever device of the present invention developed to achieve the above object includes a shift lever having a lower lever member and an upper lever member connected to an upper end of the lower lever member by a support shaft so as to be able to stand and fall. A shift lever device having a connecting mechanism capable of fixing the upper lever member to a position where the upper lever member is erected with respect to the lower lever member, wherein the connecting mechanism is provided above the lower lever member so as to be vertically movable. A tubular slide member that can be fitted to the lower end of the member, an urging means that urges the slide member in the direction of raising it, a locking portion provided on the slide member, and a detent plate side The first portion is provided on the member and receives the locking portion to allow the slide member to descend when the shift lever is in the P range. A guide portion having a second portion for preventing the slide member from descending by inserting the locking portion when the lever is not in the P range, and a direction provided on the slide member for pushing down the slide member. It is equipped with an operation part that can be moved to.

[0007]

[Action]

 When the upper lever member is upright with respect to the lower lever member, the lower end of the upper lever member is fitted into the slide member to maintain the locked state, so that the lower lever member and the upper lever member are Are integrated with each other.

When the shift lever is moved to a position other than the P range, the locking portion moves along the second portion of the guide portion. In this case, the slide member is prevented from moving in the vertical direction due to the fitting between the locking portion and the second portion, so that the upper lever member cannot be tilted to the lying position. Therefore, normal shift operation can be performed using this shift lever.

When the shift lever is in the P range, the locking portion of the slide member can enter the first portion of the guide portion. In this state, if the slide member is pushed down by the operating part, the slide member and the upper lever member will be disengaged from each other and the lock will be released, so that the upper lever member can be rotated to the fall position. It becomes Noh.

When the upper lever member is returned from the lying position to the standing position, when the upper lever member is rotated to the standing position with respect to the lower lever member, the biasing means raises the slide member, and the slide member moves upward. It fits with the lower end of the lever member and returns to the locked state.

The shift lever 13 is a two-divided type composed of a lower lever member 21 and an upper lever member 22. The lower lever member 21 constitutes the lower half of the shift lever 13, and the upper lever member 22 constitutes the upper half of the shift lever 13. The lower lever member 21 includes a lower lever main body 25 made of a round pipe and an upper end member 26 fixed to the upper end of the lower lever main body 25. The upper lever member 22 includes an upper lever main body 27 made of a round pipe, and a lower end member 28 fixed to the lower end of the upper lever main body 27. Both end members 26, 28 are rotatably connected by a support shaft 29 as a hinge.

As shown in FIG. 2 and the like, a detent pin 30 that projects in the horizontal direction is provided at the axially intermediate portion of the lower lever member 21. The detent pin 30 is inserted into an elongated hole 31 formed in the lower lever member 21 along the axial direction, and is movable within the length range of the elongated hole 31. The detent pin 30 engages with a predetermined portion of the stopper groove 16 of the detent plate 15 to prevent erroneous operation of the shift lever 13.

The detent pin 30 is provided on the slider 35. The slider 35 is accommodated inside the lower lever member 21 so as to be slidable in the axial direction, and is biased in the upward direction by the elastic force of the compression spring 36. The upper end 37 of the slider 35 is located near the upper end of the lower lever member 21.

On the other hand, the upper lever member 22 includes a grip 45 made of synthetic resin. A push-type button 46 is provided on the upper end of the grip 45. The button 46 is biased upward by a spring 47. The lower end of the operation rod 50 connected to the button 46 is in contact with the upper end member 51a of the intermediate rod 51. The intermediate rod 51 extends downward through the inside of the upper lever member 22 so that the lower end 52 of the intermediate rod 51 faces the upper end 37 of the slider 35 so that it can come into contact with and separate from the upper end 37.

The intermediate rod 51 is vertically movable in the axial direction of the upper lever member 22, and is preferably urged upward by an appropriate elastic member 55. Therefore, when the button 46 is pushed in the state shown in FIG. 1, the intermediate rod 51 descends within the upper lever member 22 by a predetermined amount, so that the slider 35 is pushed and the detent pin 30 is lowered. It is a composition.

The lower lever member 21 and the upper lever member 22 can be fixed and released from each other by a connecting mechanism 60. The connecting mechanism 60 is configured as described below.

A cylindrical slide member 61 is provided so as to surround the outer side of the upper end member 26 of the lower lever member 21. The slide member 61 is provided so as to be able to move up and down from a raised position shown in FIG. 3 to a lowered position shown in FIG. When the slide member 61 is in the raised position, the slide member 61 projects above the upper surface of the upper end member 26 so that the lower end member 28 of the upper lever member 22 can be fitted into the slide member 61. ..

An operation unit 65 is provided on the upper end side of the slide member 61. The operating portion 65 is located in the vicinity of the front wall 17a of the cover 17 and is shaped so that it can be pushed down with a finger.

The slide member 61 is biased in a rising direction by a coil spring 70 as an example of biasing means. The coil spring 70 is provided in a compressed state between a spring seat 71 provided on the lower lever member 21 and the slide member 61, and generates an elastic force in a direction of pushing up the slide member 61.

As shown in FIGS. 4 and 5, etc., a pin-shaped locking portion 75 is provided on a side surface portion of the slide member 61. The locking portion 75 is adapted to enter a guide groove 81 as an example of a guide portion provided on the member 80 on the detent plate side. The guide groove 81 includes a first portion 82 provided in a vertical direction in a front portion (P range side) of the member 80, and a second portion 83 that is continuous from the upper end of the first portion 82 in the horizontal direction. Become. The second portion 83 has an arc shape with the pivot shaft 12 of the shift lever 13 as the center.

The member 80 provided with the guide groove 81 may be a part of the detent plate 15, or a member separate from the detent plate 15 may be attached to the detent plate 15 by an appropriate fixing means. It may be

Next, the operation of the shift lever device 10 having the above configuration will be described. As shown in FIG. 1 or FIG. 3, when the slide member 61 is in the raised position and the lower end member 28 of the upper lever member 22 is fitted to the slide member 61, the upper lever member 22 moves to the lower lever member. Since it is integrated with 21 and is in a locked state, a normal shift operation can be performed.

That is, when the button 46 of the grip 45 is pushed with a finger, the slider 35 is pushed down via the intermediate rod 51, and the detent pin 30 is lowered. As a result, the stopper groove 16 and the detent pin 30 are disengaged, so that the shift lever 13 can be moved from the P range to the position shown by the chain double-dashed line in FIG. 1 to perform a desired select operation. ..

When the shift lever 13 is located in a position other than the P range, the locking portion 75 is inserted into the second portion 83 of the guide groove 81, so that the operation portion 65 for unlocking is pushed down by mistake. However, the slide member 61 does not descend. Therefore, the upper lever member 22 is always fixed to the lower lever member 21 except in the P range.

When the upper lever member 22 is to be laid down, the operating member 65 is pushed down with a finger while the shift lever 13 is in the P range, and the slide member 61 is in the unlocked position shown in FIG. Down to.

By doing so, the slide member 61 is disengaged from the lower end member 28 of the upper lever member 22, so that the upper lever member 22 can be rotated about the support shaft 29, that is, can be moved in the upright / falling direction. become able to. Therefore, when the upper lever member 22 is tilted rearward in this state, the upper lever member 22 rotates about the support shaft 29, and the tilted state shown in FIG. 6 is reached.

When the upper lever member 22 is laid down, the upper end 37 of the slider 35 provided on the lower lever member 21 and the lower end 52 of the intermediate rod 51 provided on the upper lever member 22 separate from each other, and There is no hindrance to the fall motion of the lever member 22.

As described above, since the upper lever member 22 can be tilted when the vehicle is stopped or parked, it becomes easy for the occupant to move between the driver's seat and the passenger's seat, and when the user lays down on the seat, for example. However, the shift lever 13 does not get in the way. Therefore, it is particularly effective for a cab-over type truck. Moreover, in this embodiment, since the upper lever member 22 is pulled down from the P range to the rear side (shift operation side), the upper lever member 22 in the fallen state can be compactly housed near the cover 17.

In order to return the upper lever member 22 from the lying state to the original standing / locking position, the upper lever member 22 is rotated in the opposite direction to the standing state. By doing so, the slide member 61 is lifted by the elastic force of the spring 70, and the slide member 61 is fitted into the lower end member 28 of the upper lever member 22 to return to the locked state shown in FIG.
