DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift lock release device for an automatic transmission.

[0002]

2. Description of the Related Art In an automatic transmission provided in an automobile, a shift range is switched by moving a shift lever.
272361). An operation button is provided on a knob of the shift lever, and when the operation button is pressed, a position pin provided at a lower portion of the shift lever is lowered to engage with a shift range to which the shift lever has moved.

In a specific shift range, the position lock is prevented from lowering by a shift lock, so that the shift to another shift range cannot be performed.
The shift lock is connected to a solenoid, and when the solenoid is energized by a switch, the shift lock rotates in the release direction, and the position pin can be moved to another shift range. Generally, the solenoid switch is provided on the brake pedal, and when the brake pedal is depressed,
When the solenoid is energized, the shift lock is released.

Further, the shift lock can be released by a non-electrical structure. This is because the shift lock is released and the vehicle can be operated even before the battery is mounted in the factory or in the event of a battery failure.

[0005] For this purpose, an opening is formed in a panel around the shift lever, and a release button projects from the opening toward the vehicle interior. The stroke when the release button is pressed acts on the shift lock to mechanically release the shift lock. The amount of protrusion of the release button from the opening is the amount by which the release button can be pressed, and is a stroke that acts on the shift lock. Therefore, the greater the protrusion amount of the release button, the greater the stroke of the release button, and the more secure the shift lock release operation. However, if the protrusion amount of the release button is too large, the release button becomes conspicuous, and the appearance around the shift lever deteriorates. Therefore, the protrusion amount of the release button needs to be an optimum value that satisfies both the certainty of operation and the appearance.

[0006]

However, since the amount of protrusion of the release button is affected by the change in the position of the opening, even if the position of the release button itself is accurately determined, the mounting error of the panel in which the opening is provided may occur. In addition, the protrusion amount of the release button relatively varies, and it is difficult to adjust the release button to the optimum protrusion amount. In particular, when the release button is projected from a large panel such as a center console, it is necessary to move the entire large panel to adjust its mounting position, which makes the adjustment operation difficult.

The present invention has been made by paying attention to such prior art, and provides a shift lock release device for an automatic transmission in which the amount of protrusion of a release button can be easily adjusted.

[0008]

According to the first aspect of the present invention,
An opening is formed in a panel attached to the vehicle body, and a release button of the shift lock is projected from the opening toward the interior of the vehicle, and a stroke when the release button is pressed in the release direction from the interior of the vehicle acts on the shift lock. A shift lock release device of the automatic transmission for releasing the shift lock, wherein the release button comprises: a slide member supported on the back side of the panel so as to be able to approach and separate from the opening; An actuating member that is attached to the slide member so as to protrude therefrom and slidably and slidably engages with the slide member, and is attached to the slide member so as to cover an upper side of the slide member and a protruding end side of the actuation member. A cap member protruding from the opening to the vehicle interior from the opening to make the sliding member non-slidable fixed state. In a state of being slid to the location, in which mounting the cap member to the slide member.

According to a second aspect of the present invention, a holding member having an engaging surface engageable with an operating member is formed on a slide member, and the holding member operates with an inner surface of a cap member attached to the slide member. By being sandwiched between the members, the engagement surface is engaged by being pushed toward the operation member, and the operation member is brought into a fixed state in which the operation member cannot slide with respect to the slide member.

According to a third aspect of the present invention, one of the holding piece and the operating member has a groove formed along the sliding direction of the operating member, and the other has a rib engaging with the groove.

According to a fourth aspect of the present invention, the slide member has a penetrating portion through which the operating member penetrates from below, and the penetrating portion of the slide member is extended to both sides beyond the width of the holding piece and the operating member. The claw portions that are formed and engage with both ends of the through portion are formed on the cap member.

According to a fifth aspect of the present invention, a concave portion is formed at the base end of the holding piece to make the base end thin.

According to a sixth aspect of the present invention, the concave portion at the base end of the holding piece is formed outside the holding piece, and the cap member has a convex portion that engages with the recess of the holding piece.

According to a seventh aspect of the present invention, on the back side of the panel,
A housing for supporting the slide member so as to be able to approach and separate from the opening is formed.

[0015]

According to the first aspect of the present invention, before the cap member is attached, the operating member is in a slidable engagement state with the slide member. Irrespective of the mounting position of the panel, it can be set to the optimum position for the shift lock. And since the operating member and the slide member are in the engaged state,
After the operating member is at the optimum position, the slide member is moved to the position closest to the opening while maintaining the position of the operating member with respect to the slide member. Thereby, the relative position of the slide member with respect to the opening (panel) becomes constant. In addition, by positioning the slide member closest to the opening, the downward stroke of the slide member can be maximized. Then, the cap member is attached to the slide member positioned closest to the opening. By attaching the cap member, the operating member is brought into a fixed state in which it cannot slide with respect to the slide member. Accordingly, the slide member, the operating member, and the cap member are integrated to form the release button, which is one component.

Further, since the cap member is attached to the slide member having a fixed relative position with respect to the opening, the amount of projection of the attached cap member from the opening is always reliable and reliable regardless of the position of the panel. It is a constant value that is optimal in terms of appearance. Therefore, it is not necessary to adjust the protrusion amount of the release button, and there is no difficulty in the adjustment work as in the related art.
Furthermore, since the release button is integrated with the three components, the entire release button moves integrally in the release direction by the stroke of pressing the cap member, and the shift lock can be reliably released.

According to the second aspect of the present invention, before the cap member is attached, the holding piece is not pressed against the operating member.
The operating member is slidable with respect to the slide member. When the cap member is attached, the holding piece is pressed between the operating member and the cap member by being sandwiched between the operating member and the cap member, and the operating member is brought into a fixed state in which the operating member cannot slide on the slide member. Therefore, by mounting the cap member, sliding and fixing of the operating member can be reliably switched, and setting of the release button is easy.

According to the third aspect of the present invention, the positioning of the operating member in the width direction in the through portion can be performed by the engagement of the groove and the rib.

According to the fourth aspect of the present invention, since the claw portion of the cap member is engaged using the both ends of the through portion, a special structure for engaging the claw portion with the slide member needs to be formed. And the molding of the cap member is facilitated.

According to the fifth aspect of the present invention, since the concave portion is formed in the base end portion of the holding piece to make the base end portion thin, the holding piece is easily bent in a direction away from the operating member, The sliding resistance of the operating member in the through portion is reduced.

According to the sixth aspect of the present invention, the protrusion of the cap member is engaged with the recess of the holding piece, thereby preventing the cap member from coming off the slide member. The cap member may be provided with both the protrusion and the claw portion, and when the protrusion is formed, the claw portion may be omitted.

According to the seventh aspect of the present invention, since the housing for supporting the slide member is provided on the panel side, the release button can be attached to the panel before being assembled to the vehicle body.

[0023]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 to FIG. 7 show a first embodiment of the present invention. Reference numeral 1 denotes a shift lever, and a panel 2 to be mounted on a vehicle separately from an assembly related to the shift lever 1
From the top of the center console finisher as
It protrudes upward into the cabin. A knob 3 is attached to the upper end of the shift lever 1, and a part other than the knob 3 is a boot 4
Covered by Operation button 3a on the side of knob 3
Is provided. While pressing the operation button 3a,
By moving the shift lever 1 back and forth, a desired shift range is selected. An indicator panel P indicating the selected shift range is provided on the side of the shift lever 1. Indicator panel P
A release button 5 is provided in a protruding state in front of.
The structure of the release button 5 will be described later.

Next, the structure below the shift lever 1 will be described. A position plate 6 is provided below the shift lever 1, and a gate 7 is formed at the center of the position plate 6. An engagement portion corresponding to each shift range is cut out at the upper edge of the gate 7.
When the operation button 3a of the knob 3 is pressed, the position pin 8 provided at the lower part of the shift lever 1 is lowered, and an engagement portion according to the position of the shift lever 1 is selected. The frontmost (right side in FIG. 2) engaging portion 9 of the gate 7 corresponds to “parking”. A shift lock 10 is rotatably provided below the engagement portion 9.

The shift lock 10 has a solenoid 11
Are connected, and the shift lock 10 can be rotated in the R direction in FIG. The switch for the solenoid 11 is provided on a brake pedal (not shown). When the brake pedal is depressed, the solenoid 11 is energized, the shift lock 10 rotates in the R direction, and the lower portion of the engagement portion 9 is moved. It is designed to be open. Although the shift lock 10 is connected to the solenoid 11, it can easily rotate in the R direction when a force is applied. Therefore, when the position pin 8 enters the front end engaging portion 9 from the adjacent engaging portion. Enters the engagement portion 9 while pushing the shift lock 10 to the R side with the position pin 8. However, once the position pin 8 enters the engagement portion 9 and tries to escape from it, it hits the upper end of the shift lock 10, so that the shift lock 10 does not rotate, and the solenoid 11 is energized to move the shift lock 10 to the R side. Unless it is rotated, it cannot come out of the engagement portion 9.

The shift lock 10 has a lever 1
A release rod 13 is provided obliquely at a position adjacent to the lever 12, and the lower end of the release rod 13 pushes the lever 12 to force the shift lock 10 to the R side. Can be rotated. The release rod 13 is provided with a spring 14 so that the release rod 13 returns to its original position after pressing the lever 12 with the release rod 13. The lower end of the release button 5 is in contact with the upper end of the release rod 13, and by pressing the release button 5 downward, the release rod 13 is pushed to shift the shift lock 10 without using the solenoid 11.
It can be turned to the R side.

Next, the structure of the release button 5 will be described. The release button 5 includes a slide member 15 and an operation member 16.
And a cap member 17. The slide member 15 has a rectangular shape having a substantially H-shaped cross section and a flange 18 projecting vertically from an edge of substantially the entire circumference, and a rectangular through portion 19 is formed at the center. A part of the edge of the long side portion of the through portion 19 extends upward to form a pair of holding pieces 20 facing each other.
The inner surfaces of the holding pieces 20 facing each other are horizontal uneven surfaces 21, and a groove 22 is formed at the center in the vertical direction. Further, a concave portion 23 in a horizontal direction is formed from the outside at the base end of the holding piece 20 to make the base end thin. Therefore, the holding piece 20 is easily bent around the base end. The width of the holding piece 20 is smaller than the width of the penetrating portion 19 in the long side direction.
9 are in a state in which both ends extend outside the holding piece 20 (and the operating member 16).

The sliding member 15 is housed in advance in a housing 25 attached to the opening 24 of the panel 2 from below. The vertical size of the housing 25 is larger than the vertical size of the slide member 15, and the slide member 15 can slide up and down within the housing 25 by the difference. An opening 26 corresponding to the opening 24 of the panel 2 is formed on the bottom surface of the housing 25, and the operating member 16 can protrude downward from the opening 26.

The operating member 16 is a substantially rod-shaped member having a large-diameter stopper 27 formed in the middle thereof. The upper part of the operating member 16 has a substantially rectangular cross-section with a horizontal section. On a pair of opposed side surfaces on the long side, a horizontal uneven surface 28 is formed. Further, a rib 29 is formed along the vertical direction at the center of the uneven surface 28. The portion of the operating member 16 on which the uneven surface 28 is formed is inserted into the through portion 19 of the slide member 15 from below. By inserting the operating member 16 into the through portion 19, the uneven surfaces 21, 28 of the operating member 16 and the holding piece 20 are formed.
When the holding members 20 correspond to each other and are strongly pressed against the operating member 16, the operating member 16 is fixed in a non-slidable state at the through portion 19, and the upper end side of the holding member 20 can be expanded so as to separate from the operating member 16. If it is made free, the operating member 16 can slide on the penetrating portion 19. Uneven surface 2 of operating member 16
8 corresponds to the width of the holding piece 20, and the operating member 16
Positioning of the holding member 20 in the width direction is performed by engagement of the rib 29 of the operating member 16 with the groove 22 of the holding member 20. Therefore, even when the operating member 16 is inserted into the through portion 19, a predetermined interval is left on both sides of the operating member 16 up to both ends of the through portion 19.

The cap member 17 has a substantially rectangular shape when viewed from above and is in the shape of a container with an open lower side, and downward claw portions 30 are formed at lower ends on both sides thereof. The cap member 17 has such a size that it can be inserted into the opening 24 of the panel 2 from above and that the upper end of the holding piece 20 and the operating member 16 can be housed inside. Then, the cap member 17 is inserted from the opening 24 and the claw portion 30 is engaged with an extra space portion of the through portion 19 between both sides of the operation member 16 and both ends of the through portion 19, whereby the cap member 17
Is attached to the slide member 15 to prevent it from coming off. In the attached state, the lower end of the cap member 17 other than the claw portion 30 is connected to the flange 11 of the slide member 15.
It comes into contact with the upper surface of the portion surrounded by 8. As described above, since the claw portion 30 of the cap member 17 is engaged using the extra space portion other than both ends of the through portion 19, it is necessary to form another structure for attaching the cap member 17 to the slide member 15. Therefore, the molding of the cap member 17 is easy.

Next, the procedure for mounting the release button 5 on the vehicle will be briefly described. First, a device in which the shift lever 1, the shift lock 10, the release rod 13 and the like are assembled in advance is attached to a predetermined position of the vehicle. Thereafter, the shift lever 1 is exposed, but the panel 2 covering the other mechanisms is mounted on the device in a state where the slide member 15 and the operation member 16 are assembled in advance, and then the release button 5 is operated by pressing the release button 5 on the operation member 16. Attach to In this mounting process, the mounting of the device is not different from the conventional one, so that the detailed description will be omitted, and the mounting process of the release button 5 and the cap member 17 will be described in detail below.

First, the procedure for attaching the operating member 16 of the release button 5 to the opening 24 of the panel 2 will be described.
As shown in FIG. 5, the operating member 1 is stored in advance in a housing 25 fixed to the lower surface of the panel 2, and is inserted into the through portion 19 of the slide member 15 at the lowermost end in the housing 25.
6 is inserted from the lower side until the stopper 27 contacts the lower surface of the slide member 15. This operating member 16
Before the cap member 17 is attached, the base end of the holding piece 20 may be thin and the upper end of the holding piece 20 may be easily bent outward. 28 are not strongly engaged with each other,
5 is slidable at the through portion 19.

Then, the panel 2 to which the operating member 16 is attached is attached so as to cover the device. At this time, since the operating member 16 is located on the uppermost side, as shown in FIG. 5, the lower end of the operating member 16 and the upper end of the release rod 13 are separated from each other.

Next, the operating member 16 is slid downward with respect to the slide member 15 as shown in FIG. 6, and is pushed further downward through a state in which the lower end abuts on the upper end of the release rod 13. Then, the release rod 13 is operated as shown in FIG. That is, the operating member 16 is pushed in until the shift lock 10 is moved in the release direction R. Unless the lower end of the operating member 16 pushes the upper end of the release rod 13 to release the shift lock 10 once, a loss occurs in the stroke until the shift lock 10 is released when the operating member 16 is pressed. "Optimal". However, this optimal state differs depending on the mechanism for moving the shift lock 10 in the release direction R.

Then, after the operating member 16 is at the optimum position and the pressing down of the operating member 16 is stopped, the operating member 16
And the slide member 15 are engaged with each other by the concave and convex surfaces 21 and 28, and the slide member 16 is moved by the reaction force of the spring 14 applied to the release rod 13 while the position of the operation member 16 with respect to the slide member 15 is maintained. 25, it moves to the position closest to the opening 24, that is, the upper end position. This makes the vertical stroke of the slide member 25 in the housing 25 coincide with the operation stroke of the release rod 13 (in this embodiment, since the release rod 13 moves obliquely, it becomes a vertical component of the actual operation stroke). It depends. Thereby, the shift lever 1,
Even if there is an error in the vertical mounting position of the panel 2 with respect to the device including the shift lock 10 and the release rod 13, the vertical sliding of the spring 15 and the operating member 16 can absorb the error. The position of the slide member 15 is always constant. Further, since the slide member 15 is located at the uppermost end, the downward stroke of the slide member 15 can be maximized.

Next, as shown in FIG. 8, the cap member 17 is attached to the slide member 15 located at the uppermost position through the opening 24 from above. That is, the claw portion 30 of the cap member 17 is engaged with both ends of the through portion 19, and the holding piece 20 and the upper end portion (projecting end) of the operating member 16 are engaged.
Is stored in the cap member 17. Cap member 17
By attaching the cap member 17 to the cap member 17.
Since the inner surface is pushed toward the operation member 16, the two uneven surfaces 21 and 28 are strongly engaged with each other, and the operation member 16 is in a fixed state in which the operation member 16 cannot slide on the slide member 15 by the through portion 19.

Therefore, by attaching the cap member 17, the slide member 15, the operating member 16, and the cap member 17 are integrated to form the release button 5, which is one component. Further, the amount of protrusion T of the cap member 17 from the opening 24 is always constant regardless of the vertical position of the panel 2 with respect to the device. The reason why the protrusion amount T of the cap member 17 becomes constant as described above is that the slide member 1
This is because the cap member 17 is attached to the slide member 15 of the slide member 15 at the uppermost position. The protrusion amount T of the cap member 17 is an optimum constant value in terms of the reliability and appearance of the operation, and the optimum protrusion amount T can be obtained without any troublesome adjustment work.

Further, since the release button 5 is integrated with three members, when the cap member 17 is pressed, the release button 5
The whole moves downward with the maximum stroke corresponding to the protrusion amount T of the cap member 17. Since the lower end of the cap member 17 is in contact with the upper surface of the slide member 15, the pressing force is
It is reliably transmitted from the lower end of the cap member 17 to the slide member 15, and no deformation occurs in the transmission path of the pushing force. If the release button 5 descends with the maximum stroke,
Since the release rod 13 is largely pushed, the shift lock 10 can be largely rotated in the R direction, and the reliability of the release operation increases.

As described above, according to this embodiment, even if there is a vertical mounting error in the panel 2 with respect to the device related to the shift lever 1, the protrusion amount T of the cap member 17 can be adjusted tediously. It is possible to always maintain an optimum constant value in terms of the reliability and appearance of the operation without any operation.

In this embodiment, the slide member 15
Is supported by the housing 25 attached to the panel 2. However, if the slide member 15 can be supported up and down to a position close to the opening 24, it can be supported by another member attached to a portion other than the panel 2 without using the housing 25. May be.

FIG. 9 is a diagram showing a second embodiment of the present invention. In the second embodiment, the claw portion is omitted from the cap member 31, and instead, a convex portion 32 that engages with the concave portion 23 of the holding piece 20 is formed on the inner surface of the lower end of the cap member 31. Therefore, by attaching the cap member 31, the convex portion 32 is engaged with the concave portion 23, and the cap member 31 is prevented from coming off. Also, the cap member 3
Since the lower end of 1 is in contact with the upper surface of the slide member 15, the force pressing the cap member 31 is reliably transmitted to the slide member 15. The cap member 31 may have both the projection 32 according to this embodiment and the claw according to the above embodiment. If both are provided, the cap member 31 is more securely attached to the slide member 15.

FIGS. 10 and 11 show a third embodiment of the present invention. In the third embodiment, the holding piece 20 of the slide member 15A is erected only on one side of the long side portion of the penetrating portion 19, and the shape of the holding piece 20 and the operating member opposed to the holding piece 20 The uneven surface 28 on the side surface of 16A is the same as in the first embodiment. And, compared to the first embodiment, on the side where the other holding pieces are abolished,
Only the groove 22A is present, and the corresponding side surface of the actuating member 16A is planar, and the upper end is tapered at the center thereof to form a rib 29A extending along the vertical direction. The rib 29A is provided on the inner surface of the cap member 17A.
Ribs 33 are formed so as to be positioned therebetween. The lower end of the rib 33 is also tapered.
Other configurations are the same as those of the first embodiment.

According to this embodiment, since only one holding piece 20 is required, the width W of the cap member 17A becomes small,
At the same time, the opening 24A becomes smaller, which is more advantageous in terms of appearance. Then, the holding piece 20 is moved to the operation member 16A.
Is applied to the ribs 3 on the inner surface of the cap member 17A.
3 or maintained by the rib 29A of the actuating member 16A. Further, since the insertion sides of these ribs 33 and 29A are tapered, it is possible to prevent the actuating member 17A from being erroneously pushed down when the cap member 17A is attached. Since the holding piece 20 is on only one side, the operating member 16 and the uneven surface 21 of the holding piece 20 are different from those of the first embodiment.
Since the engaging force of 28 is small, the concave portion 23 is not always necessary.
