DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, as a shift device for an automatic vehicle, there is a so-called staggered gate type in which a range is switched while a change lever 2 is moved following a crank gate 1, as shown in FIG. In a shift device of the type described above, the change lever 2 is normally shift-locked in the parking range P using the solenoid 3.

[0003]

On the other hand, in a case where the shift lever 2 is to be shift-locked using an interlock cam without using the solenoid 3 as described above, the position near the operation rotation fulcrum of the change lever (low). When the interlock cam is provided at the position (2), since the moving force of the change lever 2 is strong according to the principle of leverage, the interlock cam may be damaged.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and there is little possibility that an interlock cam is damaged, and an inexpensive interlock cam, an interlock cable and an interlock mechanism can be used instead of an expensive solenoid. It is an object of the present invention to provide a vehicle shift lock device capable of performing a shift lock on a vehicle.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a shift device for an automatic vehicle which switches a range while moving a change lever following a gate. While formed on a member provided at a position higher than the fulcrum, the change lever engages when the change lever is moved to the parking range following the gate, and interlocks with the change lever when the change lever is selectively moved An interlock cam that is shift-locked is provided on the member forming the gate, and a slide block that moves the gate of the parking range in conjunction with the interlock cam is provided. Shift lever selected by While, in the interlock cam is to provide a shift lock device for a vehicle, wherein the interlock cable that links the interlocking mechanism is coupled.

According to the present invention, when the change lever is moved to the parking range and engaged with the interlock cam, and then the change lever is selectively moved, the interlock cam is interlocked and shift-locked. At this time, the interlock cam is locked at the shift lock position by the interlock mechanism linked to the interlock cable of the interlock cam. In this state, even if an attempt is made to move the change lever to another range, the shift lever is locked so that the change lever cannot be moved by the slide block. Since the gate is formed on a member provided at a position higher than the operation rotation fulcrum of the change lever, the movement force of the change lever is weak, and the shift lock is directly locked by the slide block. There is no risk of damage. Further, by providing an interlock cam or the like, the shift lock can be performed by the shift lock cable and the shift lock mechanism without using an expensive solenoid.

According to a second aspect of the present invention, if the member on which the gate is formed is an indicator at a position higher than the fulcrum of operation of the change lever, a gate forming member as a separate component is not required and the highest position can be obtained. It can be.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIGS. 1 and 3 (B), the indicator 10 of the vehicle shift device is provided at a position higher than the operation rotation fulcrum of the change lever 12, and the crank-shaped gate 11 formed on the indicator 10 is provided. The range is switched while moving the change lever 12 in accordance with the above. Gate 1 above
1, a parking range P, a reverse range R, and the like are set. Note that a separate guide plate may be disposed on the lower surface or below the indicator 10 and the crank-shaped gate 11 may be formed on this guide plate.

Shift gate 11 for parking range P
a is provided with a selection gate 11b that is connected at a substantially right angle. The shift gate 11a is normally bent in an L-shape with respect to the select gate 11b, but is extended forward by the dimension B in this example.

A guide rail 11c is formed on the inner surface of the shift gate 11a, and a slide block 13 made of synthetic resin is guided by the guide rail 11c so as to be movable in the shift direction.

An interlock cam 14 made of a synthetic resin is rotatably mounted on a lower surface of the indicator 10 near the selection gate 11b by a shaft 15, and a change lever 12 is mounted on the interlock cam 14 in a parking range. Fork portion 1 with which change lever 12 is engaged when moved to P shift gate 11a
4a and the interlock cable 16
Is provided with a cable locking portion 14b for fixing the one end 16a. When the change lever 12 is selectively moved to the selection gate 11b, the shaft 1
The fork portion 11a is rotated rightward in conjunction with the change lever 12 about the center 5 to push and move the interlock cable 16.

In the vicinity of the fork portion 14a of the interlock cam 14, an oblique guide groove 14c into which the pin portion 13a of the slide block 13 is fitted from above is formed, and is interlocked with the fork portion 14a of the interlock cam 14. Then, when the fork portion 14a rotates right (lock rotation), it slides rightward, and when the fork portion 14a rotates left (unlock rotation), it slides leftward. Right end 13 of the slide block 13
b is set such that the change lever 12 moved to the shift gate 11a of the parking range P is stopped so as not to strongly hit the fork portion 14a, and the inclined end 13c is moved from the select gate 11b to the shift gate 11a. The change lever 12 that has been selectively moved to is set so as not to strongly hit the fork portion 14a.

At the upper part of the interlock cam 14,
As shown in FIG. 3, a wire spring 17 is wound, one end 17 a of the wire spring 17 is locked to the slide block 13, and the other end 17 b is attached to a spring hook 10 a on the lower surface of the indicator 10. The slide block 13 is urged in the rightward sliding direction by the one end 17a.

The urging of the slide block 13 in the rightward sliding direction causes the pin portion 13 of the slide block 13 to move.
The interlock cam 14 is urged in the left rotation (unlock) direction via a to be held at the unlock position in FIG.

The other end 16b of the interlock cable 16 is connected to a key cylinder 20. When the interlock cam 14 is rotated right (locked) and pushes the inter cable 16, the engine key of the key cylinder 20 is moved. 21 can be extracted. The interlock cable 16 is locked at the pushing and moving position by the cable lock member 22, and when the brake pedal 23 is depressed, the lock of the cable lock member 22 is released.

With the above configuration, as shown in FIG.
When the change lever 12 is moved to the shift gate 11a of the parking range P, the change lever 12
The wire spring 17 is engaged with the fork portion 14a of the interlock cam 14 held at the unlock position by the urging force of the wire spring 17. At this time, the slide block 13 slides to the left in conjunction with the left rotation (unlock) of the interlock cam 14, and even if the change lever 12 is moved with a strong force, the change lever 12 is
Since the right end portion 13b of the third member 3 does not strongly contact the fork portion 14a, there is no possibility that the synthetic resin fork portion 14a is damaged.

When the change lever 12 is selectively moved to the selection gate 11b of the parking range P as shown in FIGS.
2 interlock cam 14 and wire spring 1
7 is turned right (locked) against the urging force of No. 7. At this time, the interlock cable 16 of the cable locking portion 14b of the interlock cam 14 is pushed and moved, and is locked by the cable lock member 22 at the pushing movement position.
This lock holds the interlock cam 14 at the lock position. At the position where the interlock cable 16 is pushed and moved, the engine key 21 of the key cylinder 20 can be extracted.

In this state, when the change lever 12 is to be moved to the shift gate 11a, the interlock cam 14 also tries to turn left (unlock) in conjunction with the change lever 12.
At the inclined end portion 13c, and cannot be moved any further, and the shift is locked. At this time, even if the change lever 12 is moved with a strong force, the change lever 1
2 is pressed against the inclined end 13c of the slide block 13 and does not strongly hit the fork 14a.
(B)], there is no possibility that the synthetic resin fork portion 14a is damaged.

Next, when the engine key 21 is inserted again into the key cylinder 20 and the brake pedal 23 is depressed, the interlock cable 16 locked by the cable lock member 22 is unlocked, and the urging force of the wire spring 17 causes the interlock cable 16 to be unlocked. The interlock cam 14 can be returned to the unlock position. When the shift lever 12 is moved to the shift gate 11 a by releasing the shift lock, the interlock cam 14 also follows and rotates left (unlocks), and is held at the unlock position by the urging force of the wire spring 17. Become like

The slide block 13 also slides to the left in conjunction with the interlock cam 14, so that the change lever 12 can be moved to the shift gate 11a without any trouble.

In the above configuration, since the gate 11 is formed on the indicator 10 provided at the highest position than the operation pivot of the change lever 12, the movement force of the change lever 12 is weak, and Since the shift lock is performed by the slide block 13, the risk of the interlock cam 14 being damaged is reduced. Further, by providing the interlock cam 14, the shift lock can be performed by the shift lock cable 16 and the shift lock mechanism 22 without using an expensive solenoid.

[0022]

As is clear from the above description, in the vehicle shift lock device of the present invention, when the shift lever is selectively moved in the parking range, the interlock cam is operated in conjunction with the shift lock operation. Since the interlock cam can be locked at the shift lock position by the interlock mechanism linked to the interlock cable, the shift lock can be performed between the shift lock cable and the shift lock mechanism without using an expensive solenoid. Further, since the gate is formed on a member (for example, an indicator) provided at a position higher than the fulcrum of operation of the change lever, the interlock cam provided on this member is damaged because the moving force of the change lever is weak. Risk is reduced.

If the member on which the gate is formed is an indicator at a position higher than the fulcrum of the operation of the change lever, a gate forming member as a separate component is not required and the highest position can be obtained. And the moving force of the change lever becomes weaker.
