DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift lever device for changing a shift range of a transmission of a vehicle.

[0002]

2. Description of the Related Art In a vehicle manufacturing process, a vehicle that has undergone a process of assembling and mounting a shift lever device for operating an automatic transmission has a shift range of the automatic transmission set to a neutral range (hereinafter referred to as "N range"). To the next step by single-wheel transfer in which the drive wheels of the vehicle are freely rotatable and only one of the left and right wheels is in contact with the floor and the wheels are rolled and conveyed while rolling. Is being transported.

In a vehicle manufacturing process, there is a step of checking whether an ignition key matches a key cylinder of a door or a trunk. In this step, it is necessary to remove the ignition key from a key cylinder of a driver's seat. is there. Here, the normal shift lever device is provided with a key interlock mechanism, and shifts the shift lever to a P position corresponding to a parking range (hereinafter, referred to as a “P range”) of the automatic transmission. Unless the driving wheels of the vehicle are locked, the ignition key cannot be removed from the key cylinder in the driver's seat.

Therefore, if the automatic transmission is changed to the "P range" by shifting the shift lever to the "P position" for the above-mentioned inspection, one-wheel conveyance becomes impossible, and the production efficiency (inspection efficiency) is increased. Causes a decrease in For this reason, even if the shift lever is shifted to the "N position" corresponding to the "N range" (that is, even if the drive wheel is rotatable), the mechanism that allows the ignition key to be removed from the key cylinder. (Hereinafter, such a mechanism is referred to as a "pseudo key interlock release mechanism") is provided in the shift lever device.

[0005]

However, such a pseudo key interlock release mechanism requires a large number of parts, although it is a mechanism required only in a vehicle manufacturing process. Become.

In view of the above, it is an object of the present invention to provide a shift lever device capable of realizing a pseudo key interlock release state with a small number of parts.

[0007]

According to a first aspect of the present invention, a shift lever device is connected to a transmission of a vehicle, and is set to the transmission by performing a shift operation from a plurality of shift positions to a predetermined shift position. A shift lever for changing the shift range to a shift range corresponding to the predetermined shift position from the plurality of shift ranges, and a key device capable of starting the engine by operating an ignition key inserted into a key cylinder. Removing the ignition key from the key cylinder by restricting the operation of shifting the shift lever to a shift position corresponding to a parking range for locking the driving wheels of the vehicle among the plurality of shift ranges. A key interlock member displaced to a release position for releasing the restriction; A holding portion that holds the key interlock member and limits the displacement of the key interlock member to the limit position; and a shift lock position that limits movement of the shift lever at a shift position corresponding to the parking range. Releasing means for forcibly moving the biased shift lock member from the shift lock position to a shift lock release position for releasing the restriction, and forcibly releasing the holding state of the key interlock member by the holding portion. , Is provided.

According to the shift lever device having the above-described structure, when the shift lever is shifted to an arbitrary shift position, the shift range of the transmission is changed to a shift range corresponding to the shift position.

When the shift lever is operated to shift to a shift position corresponding to a parking range for locking the driving wheels of the vehicle (hereinafter, this shift position is referred to as "P position" for convenience), the shift from the "P position" is performed. Shift to a shift position corresponding to another shift range, for example, a shift position corresponding to a neutral range in which the driving wheels of the vehicle can freely rotate (hereinafter, this shift position is referred to as “N position” for convenience). The shift operation of the lever is restricted by the shift lock member at the shift lock position (shift lock state).

Further, when the shift lever is shifted to the "P position", the key interlock member at the limit position is displaced to the release position, and the ignition key inserted into the key cylinder is removed from the key cylinder. The restriction is released (key interlock release state).

In this shift lever device, when the key interlock member is held by the holding portion, the key interlock member is held at the release position. Therefore, in this state, even if the shift lever is not shifted to the “P position”, the restriction on the removal of the ignition key from the key cylinder is released (pseudo key interlock release state). Therefore, if the shift lever is at the "N position" in this state, it is possible to freely remove the ignition key from the key cylinder while freely rotating the driving wheels of the vehicle.

Further, when the release means is operated while the key interlock member is held by the holding portion, the shift lock member is moved from the shift lock position to the shift lock release position, and the key interlock by the holding portion is moved. The holding state of the member is forcibly released.

Here, in the present shift lever device, the structure such as the shift lock member and the key interlock member is a structure generally used conventionally, and by adding a holding portion thereto, the above-described pseudo key interlock member is provided. An unlocked state can be realized. Therefore, the cost of parts required for realizing the pseudo key interlock release state can be greatly reduced. Moreover, the release means for forcibly moving the shift lock member to the shift lock release position is also conventionally used, and the release means releases the holding of the key interlock member by the holding portion. This eliminates the need for a special configuration for releasing the pseudo key interlock release state, and also makes it possible to significantly reduce parts costs.

According to a second aspect of the present invention, in the shift lever device of the first aspect, the shift lock member is provided on at least one of the shift lock member and the key interlock member, and the shift lock member is provided with the shift lock. When the key interlock member is in the release position and the key interlock member is in the release position, the key interlock member is engaged with the other, and the key interlock member is directed to the restriction position with the forcible movement of the shift lock member by the release means. And an engaging portion for forcibly displacing the same.

According to the shift lever device having the above structure, the engagement portion is provided on at least one of the shift lock member and the key interlock member, and the shift lock member is in the shift lock position and the key interlock member is provided. Is in the release position, the engaging portion is engaged with one of the other.

Here, when the shift lock member is forcibly displaced to the shift lock release position by the release means, the key interlock member in the release position is forcibly displaced to the limit position to force the holding state of the holding portion. At the same time, the engagement of the engaging portion with the other is released.

Therefore, in the present shift lever device, the release means only needs to be basically configured to forcibly move the shift lock member to the shift lock release position, similarly to the configuration of the conventional release means.

As shown in FIG. 1, the shift lever device 10 includes a shift lock solenoid 112. The shift lock solenoid 112 is composed of a solenoid body 116 containing a coil 114 and a core (not shown), and a rod-shaped plunger 118. The solenoid body 116 is fitted and attached to a solenoid accommodating portion 120 provided inside the side wall 16 of the base member 12, and is connected to a shift lock computer (not shown) via connection means such as a lead wire 122 and a connector 124. It is electrically connected. The solenoid body 116 has a through-hole 130 opened substantially toward the rear of the vehicle.
The plunger 118 is slidably inserted substantially in the front-rear direction of the vehicle, and the shift lock computer energizes the coil 114 to excite the core, thereby attracting the plunger 118 into the solenoid main body 116.

Further, a compression coil spring 132 is disposed substantially on the vehicle rear side of the solenoid body 116, and biases the plunger 118 substantially toward the vehicle rear side. Therefore, when the coil 114 is not energized, most of the plunger 118 projects outside the solenoid body 116 by the urging force of the compression coil spring 132. As shown in FIG. 2, the base member 1 substantially on the vehicle rearward side of the shift lock solenoid 112 is provided.
A guide wall 134 is erected on the upper side 2 in parallel with the side wall 16, and a shift lock plate 48 is arranged between the side wall 16 and the guide wall 134 so as to be slidable substantially in the vehicle longitudinal direction.

The shift lock plate 48 is a plate-like member having a thickness direction substantially in the left-right direction of the vehicle. As shown in FIG. 2, the shift lock plate 48 extends from one end face in the thickness direction (ie, a surface substantially on the left side of the vehicle). The horizontal wall portion 138 is extended, and the horizontal wall portion 138 is integrally engaged with the tip of the plunger 118. As shown in FIGS. 2 and 5, of the upper end portion of the shift lock plate 48, a portion located on the most rearward side of the vehicle is a stepped portion 142. Is substantially equal to or smaller than the height from the upper end surface of the base member 12 to the lower inner peripheral portion 98 of the detent hole 94. A limiting wall 144 whose surface direction is directed substantially toward the rearward side of the vehicle is formed from an end of the step portion 142 substantially on the front side of the vehicle. This restriction wall 144 has a detent hole 94 at the upper end.
Is substantially equal to the position of the lower end of the limiting portion 100. Therefore, the right detent protrusion 84 that is to bypass the restriction portion 100 and move toward the vehicle front side more than the restriction portion 100
Opposes the restricting wall 144 substantially along the vehicle longitudinal direction. From the upper end of the limiting wall 144, a limiting step 146 whose surface direction is directed substantially upward in the vehicle is provided. Further, the above-described cam portion is formed from an end of the limiting step 146 substantially in the forward direction of the vehicle. 50 are continuously formed.

At the limit step portion 146, the substantially vertical dimension of the shift lock plate 48 in the vehicle is equal to or greater than the height from the upper end surface of the base member 12 to the lower end portion of the limit portion 100 of the detent hole 94. Solenoid body 116
The energization of the coil 114 in the inside is released and the plunger 11

Therefore, when the detent projection 84 moves substantially toward the front side of the vehicle with respect to the restriction portion 100 of the detent hole 94, the detent projection 84 faces the restriction step portion 146 substantially along the vehicle vertical direction (see FIG. 5). However, as shown in FIG. 6, when the power to the coil 114 is released and the plunger 118 projects substantially rearward by the urging force of the compression coil spring 132, the limiting step portion 146 becomes the detent hole 94. Is located substantially on the vehicle front side than the end portion on the vehicle front direction side.

The cam portion 50 is an inclined surface substantially in the rear direction of the vehicle and substantially in the upward direction of the vehicle. When the power to the coil 114 is released, the plunger 118 is moved substantially in the rear direction of the vehicle by the urging force of the compression coil spring 132. In the protruding state (the state shown in FIG. 5), a portion of the cam portion 50 substantially on the vehicle front side with respect to the substantially vehicle rear side end portion (that is, the boundary portion with the limit step portion 146) substantially extends in the vehicle vertical direction. And faces the distal end of the release rod 46. Therefore, when the release rod 46 is displaced downward, the shift lock plate 48 is displaced substantially in the vehicle forward direction by the cam portion 50 being pressed by the distal end of the release rod 46 (the state shown in FIG. 6).

Key interlock cam 152 against the urging force of FIG.
Is forcibly turned in the direction opposite to the arrow A. At this time, the engagement cam portion 1 of the key interlock cam 152
The upper end surface of the tip of the holding member 64 abuts on the claw 210 of the holding claw 208 to restrict further turning in the direction opposite to the arrow A in FIG. 7, but exceeds the spring force of the spring 212. By applying a degree of external force to the key interlock cam 152 and rotating the key interlock cam 152, the spring portion 212 is elastically deformed, and the claw portion 210 is moved to the engagement cam portion 16.
4 temporarily leaves the turning locus.

When the key interlock cam 152 is pivoted to such an extent that the tip of the engaging cam 164 does not contact the claw 210, the spring 212 returns to its original state by its own spring force. Thereafter, when the external force applied to the key interlock cam 152 for turning the key interlock cam 152 in the direction opposite to the arrow A in FIG. 7 is released, the key interlock cam is actuated by the biasing force of the torsion coil spring 162. The pivot 152 moves in the direction of arrow A in FIG. 7, and the engaging portion 206 of the key interlock cam 152 comes into contact with the claw 210 of the holding claw 208. Here, the spring portion 212
Is greater than the biasing force of the torsion coil spring 162, the spring portion 212 is not elastically deformed only by the biasing force of the torsion coil spring 162.
Therefore, in this state, the holding portion 208 holds the engagement portion 206 in a state in which the engagement portion 206 is in contact with the claw portion 210.

Here, usually, the torsion coil spring 1
If the holding claw 208 does not hold the key interlock cam 152 against the biasing force of the
External force other than the torsion coil spring 162 acts on the key interlock cam 152 only when the detent projection 84 receiving the urging force of the compression coil spring 68 pushes up the key interlock cam 152 when 0 is at the “P position”. And the engaging cam portion 1 of the key interlock cam 152
64 turns upward from the position indicated by the alternate long and short dash line in FIG. That is, if the holding claw 208 does not hold the key interlock cam 152 against the urging force of the torsion coil spring 162 and the shift lever 20 is at the “N position”, the key interlock cam 7, the lock lever 190 should be in a key interlock state in which the removal of the ignition key 184 from the key cylinder 182 is restricted as described above.

However, the key interlock cam 1
52 is held by the holding claw 208 so that the shift lever 20 is at the “N position”, but the key interlock is released to the position where the restriction on the removal of the ignition key 184 from the key cylinder 182 is released. The vehicle turns (the pseudo key interlock is released). Therefore, in this case, although the drive wheels of the vehicle can freely rotate because the shift lever 20 is at the “N position”, the ignition key 184 can be freely removed from the key cylinder 182.

The pseudo key interlock release state described above can be achieved by using a conventional pseudo key interlock release mechanism.
0, the components for realizing such a pseudo key interlock release mechanism are basically the shift lock plate 48, the key interlock cam 152, and the holding claw 2
08. Of these, the holding claws 208 are basically the side walls 1.
6 and the shift lock plate 48
The key interlock cam 152 and the key interlock cam 152 differ in shape but are members used as a normal shift lock mechanism and a key interlock mechanism. Therefore,
The shift lever device 10 according to the present embodiment does not use members required only to realize the pseudo key interlock release mechanism (in other words, members that become unnecessary after the vehicle is completed), so that the cost is reduced. Can be greatly reduced.

Next, when the shift lock release button 44 is pressed in the pseudo key interlock release state, the button 56 is displaced downward as shown in FIG. The part 50 is pressed. As described above, the cam portion 50 has an inclined surface that is directed substantially toward the rear of the vehicle and substantially toward the upper side of the vehicle. Convert to the front side,
The shift lock plate 48 is a compression coil spring 13
And moves substantially toward the front side of the vehicle against the urging force. further,
When the shift lock plate 48 moves substantially toward the front of the vehicle, the holding bar 150 pushes the conical slope of the engagement recess 204 of the key interlock cam 152 upward. This causes the key interlock cam 152 to rotate around the pin 154 in the direction of arrow A in FIG. At this time, the engaging portion 206 of the key interlock cam 152 is engaged with the claw portion 21 of the holding claw 208 formed on the side wall 16.
7, the rotation in the direction of arrow A in FIG. 7 is restricted, but the release rod 46 engages the cam portion 50 of the shift lock plate 48, the holding bar 150, and the engagement recess 204 of the key interlock cam 152. The combined force of the rotational force when pressed and the biasing force of the torsion coil spring 162 that biases the key interlock cam 152 in the direction of arrow A in this state reduces the elastic force of the spring portion 212 of the holding claw 208. If it exceeds, the spring portion 212 of the holding claw 208 is forcibly elastically deformed, and the engagement between the engaging portion 206 and the claw portion 210 of the holding claw 208 is released. When the pressing operation of the shift lock release button 44 is released in this state, the key interlock cam 152 is rotated to a position where the elastic force of the torsion coil spring 162 is balanced, and stops at the balanced position (FIG. 7). Line state). The lever 172 is operated by the rotation of the key interlock cam 152 at this time, and the key device 180 enters the above-described key interlock state, so that the removal of the ignition key 184 from the key cylinder 182 is restricted. As described above, when the pseudo key interlock is released, the shift lever 20 is turned off.
Is in the "N position", the above operation changes the pseudo key interlock release state to the key interlock state, so that the state in which the shift lever 20 is normally in the "N position" in the state after the vehicle is manufactured. It will be in the same state.

Here, in the present shift lever device 10, the members used when changing from the pseudo key interlock state to the key interlock state are basically used as ordinary shift lock mechanisms and key interlock mechanisms. It is a member. Therefore, in shift lever device 10 according to the present embodiment, a member only for realizing a mechanism necessary for changing the pseudo key interlock release state to the normal key interlock state (in other words, after completion of the vehicle, Since unnecessary members are not used, there is an effect that the cost can be greatly reduced.

In this embodiment, the shift lock plate 48 serving as a shift lock member that moves to the shift lock release position forcibly rotates the key interlock cam 152 held by the holding claws 208 to hold the holding claws 208.
(In other words, the release rod 4
6 is a configuration in which the key interlock cam 152 is indirectly and forcibly rotated via the shift lock plate 48 to release the holding by the holding claws 208). In another configuration, a release member operated by pressing the release button 44 directly or forcibly rotates the key interlock cam 152 without the intervention of the shift lock plate 48 to release the holding by the holding claws 208. There may be.

[0054]

As described above, in the shift lever device according to the present invention, the member for realizing the pseudo key interlock release state is shared with the members used for the shift lock mechanism and the key interlock mechanism. Therefore, there are no unnecessary members after the manufacture of the vehicle. Therefore, the number of parts can be reduced as a whole of the apparatus, and the manufacturing cost can be reduced.
