Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a foldable shift lever device for a vehicle transmission, and more specifically, to a shift lever device for a vehicle transmission, and more specifically, for a shift lever device for a vehicle transmission. This invention relates to a foldable shift lever device for a vehicle transmission in which a shift lever of a shift type can be bent at a predetermined position.

[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 floor of the vehicle inside the vehicle is used to switch gears of the automatic transmission via a remote control link system (control cable, etc.).

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 move from the driver's seat to the passenger's seat.

Therefore, the shift lever conventionally installed on the vehicle floor is divided into upper and lower halves, and the two parts are connected with a pin to make the shift lever bendable, thereby making it easier to change seats. (For example, Japanese Utility Model Publication No. 56-32887 and Japanese Utility Model Publication No. 56-42729) have been proposed.

[Problem that the invention seeks to solve]

However, in the conventionally proposed foldable shift lever device, when moving the seat, the shift lever is folded and folded in the longitudinal direction of the vehicle (in the direction of shift operation for automatic transmissions and in the shift direction for manual transmissions). It becomes.

Moreover, regarding the bending operation position of the shift lever,
No measures have been taken to regulate it.

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.

In addition, if the shift lever is bent toward the rear of the vehicle and laid down, it tends to interfere with the parking brake lever, the shift lever cannot be tilted down to a sufficiently low position, and the shift lever tends to get in the way. In such cases, the folded portion may be exposed and become protruding, and clothing may be caught on the folded portion when moving the seat within the vehicle interior.

Moreover, if the shift lever is bent in the neutral position with the engine running while the vehicle is stopped, and your body accidentally touches the shift lever when moving from the driver's seat to the passenger seat, there is a risk that the transmission will operate inadvertently. There are concerns about problems such as:

Therefore, an object of the present invention is to make the shift lever that is bent and laid down less obstructive when moving the seat.

[Means for solving problems]

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

That is, in the foldable shift lever device for a vehicle transmission described above, the present invention provides a cover member that is attached to the fixed member and covers the bent portion of the shift lever, and the upper lever portion is bent toward the passenger seat only at a predetermined position. A bending guide groove is formed to allow the shift lever to move upwardly. It is characterized by a structure in which the lever part is tilted toward the front of the passenger side seat.

Specifically, taking Figures 1 to 6 as examples,
A foldable shift lever device for a vehicle transmission has a shift lever (10) disposed between a driver's seat and a passenger's seat, an upper lever part (20) on the shift knob (21) side, and a lower lever part on the transmission side. It is divided into two parts (30), and both lever parts (20, 30) are bendably connected by a joint means (40).

A cover member (70, 90) attached to the fixed member and covering the bent portion of the shift lever has a predetermined position (
Upper lever part (20) only in parking range)
A bending guide groove (
76 and 96) are formed.

Furthermore, the shift lever bending rotation center (axis *Z
-z> is the extension line (a) of the top surface of the seat and the vehicle floor (
It is set within the space (e) formed by the extension line (b) of F). The upper lever portion (20) is configured to be folded toward the front of the passenger side seat (E).

(Function) According to the above-mentioned means, at a shift position other than the predetermined position (parking range), the bending guide groove formed in the upper lever part (20) of the shift lever (10) and the cover member (70, 90) (76 and 96) do not match, and the shift lever (10) cannot be bent.

Move the shift lever (10) to the specified position (parking range)
When the upper lever part (20) and the bending guide grooves (76, 96) are aligned, the upper lever part (20)
can be folded down to the passenger side along the grooves (76, 96).

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.

In addition, by placing the upper lever portion (20) in an upright position along the bending guide grooves (76, 96) of the cover member, the shift lever (10) is returned to its original state.

In this way, the shift lever (10) can be bent only when it is shifted to a predetermined position (parking range). Further, the bending direction is regulated to the passenger seat side by the bending guide grooves (76, 96).

Moreover, the upper lever part (20) that is bent and brought down is as shown in Figures 1 and 2.
) and within the space (C) formed by the extension line (a) of the seat top surface and the extension line (b) of the vehicle floor (F), and does not get in the way when the seat is moved.

In addition, FIG. 4 is partially cut away at a plane including the knob attachment shaft 82 so that the attachment relationship of the slide stopper 80 and the stopper release knob can be easily understood.

The dust cover 90 has a box shape that covers the detent mechanism described above, and is made of a resin material. As shown in FIGS. 13 to 15, the dust cover 90 has grooves 93, 96 and 99 of similar shapes corresponding to the detent grooves 73, guide grooves 76 and arcuate grooves 79 of the detent plate 1-70. (Fig. 6). The upper wall 90b of the dust cover 90 has a curved shape centered on the axis X-x, similar to the detent plate 70, and a pair of parallel protrusions 91, 91 along the curved shape are formed on the inner surface of the upper wall 90b. ing. Both protrusions 91, 91 are installed in the gap between the outer peripheral surface of the detent plate upper wall 70b and the inner peripheral surface of the dust cover upper wall 90b, both of which have a curved shape. (FIGS. 4 and 5) This dust cover 90 serves as a guide for
It is attached to the detent plate 70 with four screws 94 tightened into holes 92 formed in the left and right side walls 90a. Further, a stopper release knob 89 made of resin is screwed onto the knob mounting shaft 82 protruding from the arcuate groove 99. A plate washer 98 is fitted onto the knob mounting shaft 82 and interposed between the detent plate 70 and the dust cover 90. Note that the lower inner circumferential surface 90c of the dust cover 90 is an inclined surface (draft angle during injection molding) from the viewpoint of sealability and assemblability with the dust boot 110, which will be described later.
It is formed as.

The slide cover 100 has a detent plate upper wall 70
It slides integrally with the shift lever 10 along the outer circumferential surface of the dust cover 90b and the inner circumferential surface of the dust cover upper wall 90b, and has the function of displaying the shift position and covering and sealing the guide groove 76 in modes other than the P range. This slide cover 1
00 is in the shape of a flexible, ultra-thin plate manufactured from a resin material, and fits into the width across flats 23 of the upper lever portion, and has a 16th plate in order to allow the upper lever portion 20 to be bent. A cutout groove 101 is formed in the end face (lower face in the figure) on the passenger seat side shown in the figure.

The dust boot 110 is made of a rubber base 112 in which a reinforcing metal plate 111 having an angular cross-section is embedded, as shown in FIG.
and a rubber seal portion 114 that is fitted and attached to an outer circumferential groove 113 formed in the base portion 112. The base 112 has three screws 115 shown in FIG.
It is attached to the lower bracket 60 in advance by fastening it to a nut 116 (FIG. 6) welded to the lower bracket 60. Then, the upper outer circumferential surface of the base 112 is tightly fitted into the inner circumferential surface 90c of the dust cover, thereby sealing the space between them. Although the dust boot 110 is shown in a free state in FIGS. 4 and 6, when it is actually mounted on a vehicle, the seal portion 114 is pushed down by the vehicle floor F shown by the imaginary line in FIG. , the edge 117 of the seal portion 114 seals between the vehicle floors F. In this way, the dust cover 110 is installed between the lower bracket 60, the dust cover 90, and the vehicle floor F, and prevents water, mud, dust, etc. from entering the vehicle interior, and also blocks noise from outside the vehicle interior.

Furthermore, the foldable shift lever device having the above configuration is disposed between the driver's seat side seat 1-D and the passenger's seat side seat E shown in FIG. 2, and its dust cover 90 is shown in FIG. It is arranged in a space C formed by an extension vAa of the upper surface of the seat shown and an extension line of the vehicle floor F.

That is, the dust cover 90 is placed in such a position that its upper wall 90b does not protrude upward from the upper surfaces of the seats D and E, and does not protrude forward beyond the surface of the raised vehicle floor F located below and in front of the seats. It is set. In other words, it does not protrude from the space C.

Moreover, the shift lever bending rotation center axis Z-Z at the position aligned with the guide grooves 76 and 96 of the detent plate and dust cover, that is, the P range position, is aligned with the extension line a of the seat top surface and the extension line of the vehicle floor F. It is set within the space C formed by. In the state shown by the broken line in FIG. 2 in which the upper lever portion 20 is tilted toward the front of the passenger seat E, the upper lever portion 20 and the shift knob 21 are accommodated in the space C. Note that 11 indicates a steering handle.

In the foldable shift lever device for a vehicle transmission configured as described above, the shift lever 10 is operated around the axis Z-Z along the detent groove 73 of the detent plate 70, and the shift lever 10 is operated around the axis Z-X. Operate to. As a result, the control lever 36 is rotated around the axis Y-Y via the pair of bevel gears 33 and 34, and the control cable (not shown) is reciprocated in the longitudinal direction of the vehicle, thereby controlling the automatic transmission (not shown). Operate the manual valve lever to switch to the specified gear.

At shift positions other than the P range, the upper lever portion 20 and the guide groove 76 formed in the detent plate do not match, and the shift lever 10 cannot be bent. When the shift lever 10 is shifted to the P range, the upper lever part 20 tries to fall down due to the spring force of the torsion spring 50, but it comes into contact with the slide stopper 80 in the guide groove 76 and stops at that position, preventing bending. be done. 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 88 fitted to the knob mounting shaft 82.

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
and the guide groove 76 provided in the detent plate 70 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 89 to the return spring 87.
Arc while resisting? n79 toward the front of the vehicle (in the direction of arrow G in FIG. 6). Then, the slide stopper 80 also rotates around the axis o - o at the same time, and the guide groove 7
Release 6.

When the slide stopper 80 is unlocked, the upper lever part 20 is subjected to a force in the direction of inclination by the torsion spring 50, so that it falls down naturally at the same time as the slide stopper 80 completes its movement, and the lower end surface of the guide groove 76 It comes into contact with and stops.

When the shift lever is tilted down, the outer diameter D+ portion of the upper lever portion 20 passes through the groove width W3 portion of the guide groove 76, and then the width across flats 23 of the upper lever portion passes through the guide groove 76.
It engages with the groove width W4 portion.

Therefore, even in the shift lever (a1) state, the upper lever portion 20 is held within the guide groove 76 with a slight gap.

When the upper lever part 20 falls, the slide stopper 80 rotates about the axis o-0 by the action of the return spring 87 and returns to the original state shown in FIG. 4 in which the guide groove 76 is closed. When the shift lever 10 is in the tilted state, the upper lever portion 20 is roughly held by the guide groove 76 of the detent plate and the inclined surface 80c of the slide stopper, and is further biased by the return spring 87 of the slide stopper to move the upper lever portion 20. It is securely held and highly safe. Furthermore, even if the shift lever is tilted down with the engine running, the gap between the upper lever portion 20 and the guide groove 76 is small and the two are biased by the return spring 87, so the rattling noise between the two will be reduced. It's hardly a problem.

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.

In particular, in a cab-over type vehicle as shown in FIG. Fold it forward and insert the upper lever part 2 into the space C formed by the extension line a of the top surface of the seat and the extension line of the vehicle floor F.
By accommodating the shift lever 10 and the shift knob 21, 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.

Subsequently, in order to return the shift lever 10 to its original state (regular P range), the following operation is performed.

That is, without operating the stopper release knob 89, the fallen upper lever portion 2o is moved along the guide groove 76 of the detent plate around the axis Z-Z while resisting the torsion spring 50. Then, the upper lever part 2
0, the slide stopper 80 also moves to the inclined surface 80c.
The guide groove 76 is then rotated around the axis 0-0 to release the guide groove 76.

Then, at the same time as the upper lever part 20 passes, the return spring 87 automatically returns to the original position where the guide groove 76 shown in FIG. 4 is blocked.

Therefore, from now on, the shift lever 10 is reliably held in its normal upright position by the slide stopper 80.

As explained above, according to this embodiment, the shift lever 10 is bent and tilted toward the passenger seat only at a predetermined position, and the bending rotation center (axis Z-Z) of the shift lever 10 is aligned with the extension line a of the top surface of the seat. and the upper lever part 20.
Since it is configured so that it can be folded down to the front of the passenger seat side (seat) H,
The folded upper lever part 20 and shift knob 21 do not protrude, making it easy to move the seat within the vehicle interior.

Furthermore, since the shift lever 10 can only be bent 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 if the shift lever is moved by mistake while moving the seat. Even if a part of the body touches the shift lever 10, the shift lever 10 is reliably held in the P range, so there is no risk that the vehicle will start moving unexpectedly, 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,
The upper lever section 20 can be released by simply moving the stopper release knob 89 of the slide stopper 80 clockwise.
The upper lever part 20 automatically falls down due to the spring force of the torsion spring 50 pressing the detent groove end face 73a of the detent plate, so that the shift lever
Extremely good bending operability.

Moreover, the torsion spring 50 for the detent mentioned above
Since the upper lever part 20 is tilted using the spring force, a new spring for tilting the upper lever part 20 is not required, and it can be manufactured at low cost. Moreover, the durability of the shift lever 10 can be improved since no unreasonable force is applied to the joint portion (bending portion) of the shift lever 10. In addition, the bent portion of the shift lever 10 is connected to the detent plate 70 and the dust cover 9.
0, there is no risk of clothes getting caught on the bent part 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
