PURPOSE:To simplify the bending structure by expanding a recessed groove, which a detent pin can pass when an upper lever part can be turned down, to the driver's seat side and integrally forming this groove as one body in a prescribed range position of a detect plate. CONSTITUTION:A guide groove 75 which allows an upper lever part 20 to bend to the assistant driver's seat side only in a prescribed range is formed on a cover member 70 covering a shift lever bending part, and a stopper 80 is provided which intercepts the guide groove 75 to stop the upper lever part 20 from bending. A recessed groove 76, which a detect pin 26 can pass when the upper lever part can be turned down, is expanded to the driver's seat side and is formed as one body in the prescribed range position of a detect plate 70. When the upper lever part 20 is turned down, the detent pin 26 placed in the upper lever part passes the recessed groove 76 provided in the prescribed range position of the detect plate 70 without interfering in the detect plate 70.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a folding shift lever device for an automatic transmission, and more specifically, the present invention relates to a folding shift lever device for an automatic transmission. This invention relates to a foldable shift lever device for an automatic transmission that is configured to be foldable.

[Conventional technology]

In recent years, shift levers of automatic transmissions in automobiles, etc.
A so-called floor shift type shift lever, in which the shift lever is disposed on the vehicle floor between the driver's seat and the passenger's seat, has become popular. A shift lever that stands upright from the vehicle floor inside the vehicle cabin is used to switch gears of the automatic transmission via a remote control link system (control cable, etc.).

By the way, as a floor shift type shift lever,
By pressing the button provided on the shift knob, the rod inserted into the shift lever is pushed down against the spring force, and the engagement between the detent pin at the lower end of the rod and the stepped portion of the detent slot formed in the detent plate is released. There are many shift levers configured to perform gear shifting operations (for example, Japanese Utility Model Publication No. 48-42420 and Japanese Utility Model Publication No. 53-34658).

In automobiles equipped with this floor shift type shift lever, the driver often gets in and out of the vehicle from the passenger seat in places where parking spaces are narrow or where traffic is heavy. In this case, when moving from the driver's seat to the passenger's seat, or from the passenger's seat to the driver's seat, the shift lever, which stands upright from the vehicle floor, becomes a protrusion that gets in the way, making it difficult to shift easily.

Therefore, the shift lever conventionally installed on the vehicle floor was divided into upper and lower halves, and the two parts were connected with a pin to make the shift lever bendable, thereby making it possible to easily change seats. An exemplary shift lever device (for example, Japanese Utility Model Publication No. 56-32887) has been proposed.

[Problem that the invention seeks to solve]

However, in the conventionally proposed foldable shift lever device for automatic transmissions, when moving the seat, the shift lever is moved in the direction of gear change operation (vehicle longitudinal direction).
It is designed to be folded down and folded down. Moreover, no means is taken to restrict the bending operation position of the shift lever.

Therefore, when the shift lever is bent toward the front of the vehicle and laid down, the tilted shift lever tends to get in the way, especially in cab-over type vehicles.

Furthermore, when the shift lever is bent toward the rear of the vehicle and laid down, it interferes with the parking brake lever and the like, making it impossible to lower the shift lever to a sufficiently low position, and the shift lever tends to get in the way. Furthermore, when the shift lever is bent, the bent portion is exposed and forms a protrusion, and it is conceivable that clothes may be caught on the bent portion when moving the seat in the vehicle interior.

Moreover, due to its bending structure, the upper lever part on the shift knob side is pushed down once against the spring along the 5-shaped pin groove formed in the lower lever part, and then the upper lever part is moved around the axis in this state. It is designed to be rotated, pulled up by a spring, and then folded down by bending the upper lever part.

Therefore, since the shift lever is located below the side of the driver's seat, it is difficult to bend the shift lever in a normal driving position.

In addition, since the upper lever part and the lower lever part are bendably connected with a pin at a position above the detent pin, the detent rod itself is divided into upper and lower halves and bendably connected with a pin. Since it is necessary to set the upper lever part and the lower lever part at the same position as the axis of the pin that connects them, there is a problem that the structure becomes complicated.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to make the shift lever that is folded and laid down less obstructive when moving the seat, to simplify the folding structure, and to improve the folding operability.

[Means for solving problems]

Therefore, the present invention adopts the following configuration as a means for solving the above-mentioned problems.

That is, the present invention provides a shift lever device for an automatic transmission in which the shift knob is provided with a button as described above, in which the shift lever is connected to an upper lever portion on the shift knob side and a lower lever portion on the transmission side at a position below the detent pin. The shift lever is divided into two parts and foldably connected by a joint means, and a guide groove is formed in a cover member that covers the bent portion of the shift lever to allow the upper lever portion to be bent toward the passenger seat only in a predetermined range. A stopper is provided to block the groove and prevent the upper lever portion from bending, and a recessed groove through which the detent pin can pass when the upper lever portion is folded is provided in the predetermined range position of the detent plate and bulges toward the driver's seat side. It is characterized by being integrally molded.

Specifically, taking FIG. 1 and FIG. 2 as an example, the folding shift lever device for an automatic transmission is configured to move a rod (25) by pressing a button (24) provided on a shift knob (21). Push down against the spring force and connect the detent pin (26) at the lower end of the loft and the detent play 1-
(70) The stepped portion of the detent slot (73) (
A shift lever (10) configured to perform a gear change operation by disengaging from the shift levers 73a to 73C) is disposed between the driver's seat and the passenger's seat.

The shift lever (10) is divided into two parts at a position below the detent pin (26), an upper lever part (20) on the shift knob side and a lower lever part (30) on the transmission side. , 30) are foldably connected by a joint means (40).

Then, a cover member (
70, 90) are formed with guide grooves (75, 95) that allow bending of the upper lever portion (20) toward the passenger seat only in a predetermined range (P range), and the guide a (75)・95) and upper lever part (20)
A stopper (80) is provided to prevent bending.

Further, at the predetermined range (P range) position of the detent plate (70), a concave groove (76) through which the detent pin (26) can pass when the upper lever part is folded is bulged toward the driver's seat side. It is integrally molded.

[For production]

According to the above-mentioned means, when the button (24) provided on the shift knob (21) is pressed, the rod (25) is pushed down;
The detent pin (26) at the lower end of the loft and the step (7) of the detent slot (73) formed in the detent plate.
3a to 73c) are disengaged. In this state, a desired shift position is selected.

By the way, in a range other than the predetermined range (P range), the upper lever part (20) of the shift lever and the guide grooves (75, 95) formed in the cover member do not match, and the shift lever (10
) cannot be folded.

When the shift lever (10) is shifted to the predetermined range (P range), the upper lever part (2o) and the guide grooves (75, 95) of the cover member align, and the shift lever (10) is shifted to the predetermined range (P range).
0) is a bendable position. However, the stopper (8
0) prevents the upper lever portion (2o) from being bent.

Therefore, when the stopper (80) is removed, the guide grooves (75, 9
5) is opened, and the upper lever part (2o) is guided through the guide groove (75).
・It can be folded down to the passenger side along 95).

When the upper lever part (20) is tilted down, the detent pin (26) located in the upper lever part is moved so as not to interfere with the detent plate (70) at the predetermined range (P range) of the detent plate (70). ) in the concave groove (76).

Then, with the shift lever in the tilted state, the driver's seat is moved, that is, from the driver's seat to the passenger seat side, or from the passenger seat to the driver seat side.

Further, in contrast to the above, the shift lever (1o) is returned to its original state by placing the upper lever portion (2o) in an upright state along the guide grooves (75, 95) of the cover member.

In these figures, 10 indicates the entire shift lever, which is disposed substantially upright between a driver's seat and a passenger seat (not shown). The shift lever 1O is divided into two parts, an upper lever part 20 of the shift knob 21 and a lower lever part 30 on the transmission side, both of which are foldably connected by a coupling means 40.

That is, a pipe-shaped rotating shaft 22 is welded to the lower end of the upper lever portion 20, as shown in FIG. On the other hand, the lower lever portion 30 is comprised of a fork-shaped shift lever support 31 and a pipe-shaped rotating shaft 32, as shown in FIGS. 1 and 2, and both are integrated by welding. A bolt 41 passes through a hole formed in the support 31 and is fastened with a nut 42 via a spring washer. The pipe-shaped rotating shaft 22 of the upper lever portion is concentrically arranged on the outer periphery of the bolt 41 via a collar 43 and a pair of resin flanged bushoires 44, and the upper lever portion 20 is connected to the axis Y of the bolt 41, -Y is coupled so as to be rotatable in the left-right direction (vehicle width direction) in the paper of FIG.

The upper lever part 20 has a pipe shape, and a shift knob 21 is fixed with screws or screws to the upper end thereof. Further, a long hole 23 extending in the axial direction is formed at the lower end position of the upper lever portion 20.

A detent rod 25 is inserted into the upper lever portion 20 so as to be freely movable in the axial direction, and its upper end is connected to a button 24 provided at the shaft center of the shift knob 21, and its lower end is a detent rod. A large diameter support piece 27 with a pin 26 is connected. A compression coil spring (return spring) 28 is interposed between the upper lever portion 20 and the button 24.
The button 24 is always urged upward.

The detent pin 26 extends through the elongated hole 23 of the upper lever portion, and its end on the driver's seat side protrudes largely to engage with the detent slot of the detent plate, as shown in FIG.

In this way, by pressing the button 24 provided on the shift knob, the detent rod 25 is pushed down against the spring force of the spring 28, and the detent pin 25 at the lower end of the rod is pushed down.

The earth wall 70b has a curved shape centered on the central axis (axis X-X) of the pair of holes 72, as shown in FIGS. Part 20
An open lower lower 4 is formed that allows rotational movement in the longitudinal direction of the vehicle.

A bolt 45 extending through a pair of holes 72 formed in the side wall of the detent plate 70 is fastened to the detent plate 70 with a Nand 46 via a spring washer. Similar to the coupling means 40, the pipe-shaped rotating shaft 32 of the lower lever portion is concentrically arranged on the outer periphery of the bolt 45 via a collar and a pair of flanged bushings made of resin.

In this way, the shift lever 10 is moved along the axis X-X of the bolt 45.
It is rotatably supported in the left-right direction in the paper of FIG. 1 (vehicle front-rear direction) about the center. The shift position of the shift lever 10 is from the front of the vehicle to the parking range (P range).

They are arranged in a line in six positions: range), drive range (D range), second range (2 range), and low range (L range).

Further, the pipe-shaped rotating shaft 32 has a control lever 33 M? It is connected to g. control lever 33
A pin 34 is fixed to the tip of the control cable, and the end of the control cable is fitted to this pin 34 via a rubber bush (not shown). In this way, when the shift lever 10 is rotated around the axis X-X, the control lever 33 is also rotated around the axis X-X, causing the control cable to reciprocate in the longitudinal direction of the vehicle to shift the automatic transmission to a predetermined gear position. It is configured to switch and operate.

Now, the detent plate 70 includes the
As shown in the figure, a guide groove 75 is formed that allows the upper lever portion 20 to be bent toward the passenger seat only in the P range position.

That is, in the P range position, a guide groove 75 is formed continuously from the open lower 4 from the earthen wall 70b to the side wall 70a on the passenger seat side. This guide groove 75 has a width slightly larger than the outer diameter of the upper lever portion 20, and is approximately orthogonal to the shift lever speed change operation direction, with an axis extending from its center line C extending from the axis X-X. It extends in the direction of passing.

Further, at the P range position of the detent slot 73 of the detent plate, a groove 76 extending upward from the detent slot 73 is formed as shown in FIG. The groove 76 is formed by integrally molding a portion of the side wall 70a bulging toward the driver's seat as shown in FIG.

Moreover, the upper ends of the grooves 76 are connected without being opened in the shape of a notch, as shown in FIG. 9 in particular. Also,
The width of the concave groove 76 is set larger than the outer diameter of the detent pin 26, and like the guide groove 75, the axis extending from its center line C extends in the direction passing through the axis XX. . Further, the depth dimension of the groove 76 (the dimension of the recess on the driver's seat side) is determined so that the detent pin 26 does not interfere with it, as shown by the imaginary line in FIG. thus,
The groove 76 allows the detent pin 20 located inside the upper lever part 20 to be inserted into the upper lever part 20 when the upper lever part 20 is tilted down.
It is designed to allow the passage of.

In addition, the side wall 70a of the detent plate 70 on the passenger seat side
A pin 77, to which an end of a return spring of a slide stopper to be described later is locked, is press-fitted and welded in parallel to the axis XX.

Furthermore, an arcuate groove 78 centered on the shaft 61x-x is formed in the upper edge thereof, into which a mounting shaft of a stopper release knob, which will be described later, is fitted.

Reference numeral 80 designates a slide stopper, which, as shown in FIG. It has a cursor shape. A pipe-shaped rotating shaft 82, which is fitted onto the bolt 45, is welded to the lower end of the side wall. The outer peripheral surface of the upper wall 80b has a curved shape centered on the central axis (axis X-X) of the pipe-shaped rotating shaft 82, and
It is designed to slide along the inner circumferential surface of the earthen wall.

Further, on the side wall 80a of the slide stopper, a pin 83 on the inner circumferential side of which is engaged with one end of a return spring, which will be described later, and a pin 83 on the outer circumferential side of the side wall 80a of the detent plate.
The knob mounting shafts 84 that fit into the respective knobs 78 are aligned with the axis X-
It is integrally fixed parallel to x by means of press fitting, welding, caulking, etc. Note that the front end surface (left end surface in FIG. 4) 80c of the slide stopper 80 is formed as an inclined surface forming an angle θ with respect to the center line C of the guide groove 75.

The slide stopper 80 is rotatably supported around the axis X-X of the bolt 45 in the same way as the shift lever 10 by fitting a pipe-shaped rotating shaft 82 into the port 45 as shown in FIG. . The rotation angle of the slide stopper 80 is regulated within a certain range of angles by the abutting relationship between the knob mounting shaft 84 and the arcuate groove 78 of the detent plate.

Reference numeral 85 designates a return spring (torsion spring) for the slide stopper 80, the middle part of which is wound around the pipe-shaped rotating shaft 82, and both ends of which are respectively engaged with the pin 77 of the detent plate and the pin 83 of the slide stopper. There is. This return spring 8
5 urges the slide stopper 80 in a direction to close the guide groove 75 so that the shift lever 10 does not fall even when it is in the P range. That is, the slide stopper 8
0 is biased to the left in the paper of Fig. 4 (toward the front of the vehicle),
It is held in the position shown in FIG. 4 where its front end surface is in contact with the protrusion 79 formed on the detent plate. good).

In this way, the slide stopper 80 blocks the guide groove 75.
During normal operation, the shift lever 10 prevents bending of the shift lever 10 and functions as a part of the detent plate 70, and also closes the guide groove 75 to ensure sealing performance. 86
is a plate washer that is fitted onto the knob mounting shaft 84 and interposed between the detent plate 70 and the slide stopper 80.

Reference numeral 90 denotes a resin cover, which has a box shape and covers the aforementioned detent mechanism. The resin cover 90 covers the open lower portion 4, the inner ear 475, and the circular arc groove 7 of the detent plate 70, as shown in FIG.
8, an opening 94, a guide groove 95, and an arcuate groove 98 are provided. The upper wall 90b has a curved shape centered on the axis bix-x, similar to the detent plate 70, and a pair of parallel protrusions 92 (FIG. 2) along the curved shape are formed on the inner surface of the upper wall 90b. ing. Both protrusions 92 serve as guides for a slide cover 100 that is inserted into the gap between the outer peripheral surface of the upper wall of the detent plate and the inner peripheral surface of the upper wall of the resin cover. and,
This resin cover 90 is fixed to the front and rear upright portions 64 welded to the lower bracket 60 with four screws 93. Further, a stopper release knob 81 made of resin is screwed onto the tip of the knob attachment shaft 84 protruding from the arcuate groove. 9
6 is fitted to the knob mounting shaft 84 and is attached to the detent plate 70.
This is a plate washer interposed between the resin cover 90 and the resin cover 90.

A slide cover 100 slides in conjunction with the shift lever 10 along the outer circumferential surface of the upper wall of the detent plate and the inner circumferential surface of the upper wall of the resin cover, and displays the variable J position, and also displays the above-mentioned guide groove 75 in positions other than the P range. and has the function of covering and sealing 95. This slide cover 1
00 has a flexible, ultra-thin plate shape (for example, about 0.811 plate thickness) made of a resin material such as polyamide resin, and the upper lever part 20 is located in the center of the plate.
A cutout groove 105 is formed in the passenger seat side end surface (left end surface in FIG. 2) to allow the upper lever portion 20 to be bent.

In the foldable shift lever device for an automatic transmission configured as described above, when the shift lever 10 is in a position other than the P range, the detent pin 26 is urged upward by the spring force of the spring 28, and the detent slot 73 is in contact with the upper end surface of. Further, when the shift lever 10 is in the P range, the detent pin 26 is in contact with the upper end surface of the elongated hole 23.

Next, when the button 24 is pressed and the detent rod 25 is pushed down against the spring force of the spring 28, the detent pin 26 at the lower end of the rod moves downward along the elongated hole 23. Then, the engagement between the detent bin 26 and the stepped portions 73a to 73C of the detent grooves is released. In this state, the shift lever 10 is operated around the axis Fp1 x - x along the lower portions 4 and 94 . This results in
By rotating the control lever 33 and reciprocating the control cable (not shown) in the longitudinal direction of the vehicle, the manual valve lever of the automatic transmission (not shown) is actuated to selectively shift to a desired gear. (Note: Do not press the button 24 between N range, D range, and 2 range (speed change operation is possible in both ranges).

At shift positions other than the P range, the upper lever portion 20 and the guide grooves 75 and 95 do not match, and the shift lever 10 cannot be bent.

Then, when shift lever 10 is shifted to P range,
The upper lever portion 20 and the guide grooves 75 and 95 match,
This is the position where it can be bent. Then, the upper lever part 20 tries to fall down due to the spring force of the torsion spring 50, but comes into contact with the slide stopper 80 and stops at that position, thereby preventing bending. At this time, the load applied by the torsion spring 50 in the direction of tilting the upper lever portion 20 is received by the detent plate 70 mainly through the plate washer 86 fitted to the knob mounting shaft 84.

When bending and tilting the shift lever 10, the operation is as follows.

First, shift lever 10 to P range. In this shift position, the upper lever portion 20 of the shift lever
The guide grooves 75 and 95 coincide with each other, and the shift lever becomes a bendable position. However, the shift lever bending operation is prevented by a slide stopper 80.

Next, move the stopper release knob 81 to the return spring 85.
It is moved along the arcs 78 and 88 in the direction of the arrow in FIG. 4 (towards the rear of the vehicle) while resisting.

Then, the slide stopper 80 also rotates around the axis XX at the same time, releasing the guide grooves 75 and 95.

When the slide stopper 80 is unlocked, the torsion spring 50 is acting on the upper lever part 20 in the direction of inclination, so that the slide stopper 80 naturally falls down about the axis Y-Y at the same time as the movement of the slide stopper 80 is completed. . When the upper lever part 20 is tilted down, the upper lever part 2
The detent pin 26 located within 0 passes through the groove 76 provided in the detent plate in the direction of the arrow in FIG. 9 without interfering with the detent plate 70.

In this way, the upper lever portion 20 comes into contact with the lower end surface of the guide groove and stops, as shown by the imaginary line in FIG.

When the upper lever part 20 falls, the slide stopper 80 rotates about the axis X--X by the action of the return spring 85 and returns to the original state shown in FIG. 2 in which the guide grooves 75 and 95 are closed. When the shift lever 10 is in the tilted state, the upper lever portion 20 is roughly held by the guide grooves 75 and 95 and the inclined surface 80c of the slide stopper, and is further biased by the return spring 85 of the slide stopper to securely hold the upper lever portion 20. to hold.

Then, with the shift lever in the tilted state, the driver's seat is moved, that is, from the driver's seat to the passenger's seat, or from the passenger's seat to the driver's seat.

Next, return the shift lever 10 to its original state (regular P range).
``To return to ``, operate as follows.

That is, without operating the stopper release knob 81, the fallen upper lever portion 20 is moved into the guide groove 75 around the axis Y-Y.
and 95 while resisting the torsion spring 50. Then, as the upper lever portion 20 moves, the slide stopper 80 also moves along the axis X due to the inclined surface 80C.
- Rotate around X to release guide grooves 75 and 95. Then, at the same time as the upper lever part 20 passes, the return spring 85 automatically returns to the original position where the guide grooves 75 and 95 shown in FIG. 2 are blocked. Therefore,
Thereafter, the shift lever 10 is reliably held in its normal upright position by the slide stopper 80.

Therefore, according to this embodiment, the shift lever 10 is moved from the front passenger seat (u, lJ
Since the seat can be bent and folded down, it is easy to move the seat inside the vehicle.

In particular, in the case of a cab-over type vehicle as shown in Fig. 1θ, the shift lever 10 disposed between the driver's seat side seat) D and the passenger seat side seat By folding the shift lever 10 toward the front of the seat E, the shift lever 10 that is folded down does not get in the way when moving from the driver's seat to the passenger seat, making it extremely easy to move the seat. Note that F indicates the vehicle floor and H indicates the steering wheel.

In addition, since the shift lever 10 can be bent only when shifted to the P range, in the unlikely event that the shift lever 10 is moved away from the driver's seat while the engine is running while the vehicle is stopped, or the shift lever is accidentally moved when moving the seat. Even if a part of the body touches the shift lever 10, the shift lever 10 is held in the P range, so there is no risk of the automatic transmission inadvertently operating, and it is safe.

Further, from the appearance, the fact that the shift lever 10 is foldable and the direction in which it is folded can be intuitively recognized. Moreover,
With the simple operation of moving the stopper removal knob 81 of the slide stopper to the rear of the vehicle, the upper lever part 20 is automatically collapsed by the spring force of the torsion spring 50, so the shift lever bending operability is extremely good.

Further, the shift lever 10 is moved between the upper lever portion 20 and the lower lever portion 30 at a lower surface than the detent pin 26.
Since the detent loft 25 is divided into two parts and foldably connected by the joint means 40, there is no need to bendably connect the detent loft 25 with a pin, and the structure is simple. Therefore, it can be manufactured at low cost.

Moreover, since the groove 76 provided in the side wall 70a of the detent plate on the driver's seat side is formed by integrally molding the side wall 70a by bulging toward the driver's seat, the upper end of the groove 76 is open in the shape of a notch. do not have. Therefore, the strength of the detent plate 70 is high.

Moreover, the durability of the shift lever 10 can be improved since no unreasonable force is applied to the joint portion or the bent portion of the shift lever 10. Also, shift lever 10
Since the bent portion of the shift lever is covered by the detent plate 70 and the resin cover 90, there is no risk of clothes getting caught on the bent portion when the shift lever is in the tilted state, or of getting dirty with grease applied for lubrication.

The present invention has been described in detail with respect to specific embodiments, but
The present invention is not limited to the above embodiments, but includes various embodiments within the scope of the claims. A hole is formed which opens toward the driver's seat side, and a button equipped with an inclined hole (cam hole) having a downwardly inclined surface in this large circle is inserted via a return spring, and the button is inserted into this inclined hole. A shift lever for an automatic transmission of the type configured to engage a sleeve fixed to the upper end of the detent rod and convert the substantially horizontal reciprocating motion of a button into vertical reciprocating motion of the detent rod at a sloped surface. It can also be applied to equipment. Further, it is also possible to change the structure of the joint means connecting the upper lever part and the lower lever part and the structure of the stopper.

〔Effect of the invention〕

As explained above, according to the present invention, since the soft lever is tilted toward the passenger seat side perpendicular to the direction of gear change operation,
The folded shift lever does not get in the way when moving the seat, making it easier to move the seat inside the vehicle.

Furthermore, since the shift lever can be tilted down simply by removing the stopper, the shift lever has extremely good bending operability.

Furthermore, there is no need to bendably connect the detent pins to each other (the structure is extremely durable and can be manufactured at low cost).

Also, there is a concave formed on the detent plate! Since one end of the = is connected without being opened in the shape of a notch, the strength of the detent plate does not decrease.
