Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a select lever device for an automatic vehicle that selects a range with a select lever.

<Prior Art> Generally, in an automatic vehicle, various ranges such as a parking range 2, a reverse range 3 and a drive range 4 are selected by operating a select lever 1 as shown in FIG. . The select lever 1 can be positioned and moved in each range by pushing and retracting the push button 5 by finger operation. Here, FIG. 7 shows a state in which the neutral range is selected. Such operation of the select lever 1 does not need to be performed while depressing the clutch pedal as in the case of a manual shift vehicle, so that the driving operation is easy.

<Problems to be solved by the invention> In an automatic vehicle, the engine reverses from the parking range 2 while pressing the push button without stepping on the brake pedal, despite the high engine speed such as when the engine is warming up. It is possible that the gear shifts to the range 3 or the drive range 4. When such an operation is actually performed, there is a risk that the vehicle may suddenly start against the driver's will. However, there are many drivers who are not in the habit of performing a shift change after depressing the brake pedal, and a technique for reliably preventing a sudden start of an automatic vehicle is desired.

Some of the vehicles have a device to prevent sudden start, which can be installed as option baht.
There is a problem that the device becomes large in size and has a lot of mounting space, and the weight increases remarkably.

The present invention has been made in view of the above circumstances, and a select lever that securely prevents a sudden start of a vehicle by energizing an accurate driving operation and prevents damage to members when a shift change is performed during a shift lock. The purpose is to provide a device.

<Means for Solving the Problems> The configuration of the present invention for achieving the above object includes a parking range by disengaging a detent pin protruding from a select lever and moving up and down with respect to a pattern provided on a detent plate. In a vehicle select lever device for selecting a plurality of ranges, the selector lever is operated by operating a brake pedal when the select lever is located in a parking range, and the plunger is locked to the detent pin when the brake pedal is not depressed. And a drive device that prevents the detent pin from moving up and down and that causes the plunger to be disengaged from the detent pin when the brake pedal is stepped on, in order to engage the plunger and the detent pin via an inclined surface,
It is characterized in that the diameter of the plunger is gradually reduced toward the tip and the tip is formed into a small diameter cylindrical shape.

<Operation> When the brake pedal is not depressed, the tip of the plunger is locked to the detent pin by the drive device, the detent pin cannot move up and down, and the select lever cannot shift. When the brake pedal is depressed, the drive device causes the plunger to be disengaged from the detent pin so that the detent pin can move up and down, and the select lever can shift. If the detent pin is biased in the vertical direction when the plunger and detent pin are locked, and if you try to remove the plunger as it is, an unreasonable force will be generated on the plunger and detent pin, but the plunger and detent pin Since it is locked through the inclined surface, the plunger can be released without difficulty when it is removed. If the detent pin is moved up and down with an excessive force when the plunger is not disengaged, the plunger tries to disengage from the detent pin via the inclined surface, but the plunger and detent pin are locked at the tip of the plunger to prevent disengagement. It

<Embodiment> FIG. 1 is a plan view of a vehicle select lever device according to an embodiment of the present invention, FIG. 2 is a side view thereof, and FIG. 3 is a view taken along the line III-III in FIG. FIG. 4 shows an enlarged state of the tip of the plunger.

In the figure, 11 is a select lever made of a metal rod having a rotation mechanism section 12 at the lower end, and 13 is a plurality of step-shaped patterns 1
4 is a metal detent plate provided with 4. The select lever 11 is inserted into the through hole 15 of the installation plate 16 that is attached to the vehicle body and has the through hole 15 in the center thereof.
It stands upright from 6. Select lever 11
A detent pin 17, which is vertically moved in a certain range in the axial direction by a finger operation of a push button (not shown), projects from the above. The detent pin 17 is locked to the pattern 14a at one end of the detent plate 13. Here, this pattern 14a is the detent pin 1
By locking 7 the select lever 11 is positioned in the parking range. That is, the first
The state shown in FIG. 2 and FIG. 2 is a state in which the parking range is selected.

When the select lever 11 is in the parking range, the drive device 23 that is operated by operating the brake pedal 22.
The tip 25 of the plunger 24 is locked to the detent pin 17. As shown in FIG. 4, the tip 25 of the plunger 24 has a taper portion 25 whose diameter gradually decreases toward the tip.
a and a straight portion 25b as a small-diameter columnar tip portion that is continuous with the tapered portion 25a, and the angle formed by the tapered portion 25a is set to an angle β. The plunger 24 is inserted into the solenoid 26, and projects when the solenoid 26 is not energized and retracts when the solenoid 26 is energized. The solenoid 26 is mounted in a solenoid case 26 a screwed to the installation plate 16, and the solenoid 26 is connected to a solenoid switch 27. This solenoid switch 27 is interlocked with the operation of the brake pedal 22, and when the brake pedal 22 is not depressed, the solenoid switch 27
Is off. At this time, the solenoid 26 is not energized and the plunger 24 is protruding.
When the brake pedal 22 is stepped on, the solenoid switch 27 is turned on, the solenoid 26 is energized, and the plunger 24 is attracted and retracted. Incidentally, the plunger 24
The plunger 24 can be easily made to project by bringing the other end of a return spring (not shown) whose one end is fixed to the solenoid case 26a into contact. The shift lock mechanism 30 is formed by the driving device described above.

Although the plunger 24 and the brake pedal 22 are electrically connected via the solenoid 26 in the above-described embodiment, they may be mechanically connected via the wire 31 as shown in FIG. However, the drive source of the plunger 24 is not limited. Further, as shown in FIG. 6, it is possible to move the plunger 24 in a direction orthogonal to the detent pin 17.

Next, the operating state of the select lever device having the shift lock mechanism 30 described above will be described. Fig. 1 and 2
In the figure, the select lever 11 is located in the parking range,
Further, the brake pedal 22 is not depressed.
At this time, the detent pin 17 is locked to the pattern 14a of the detent plate 13. The plunger 24 is locked to the detent pin 17 in a protruding state. When a push button (not shown) of the select lever 11 is pressed to perform a shift change in this state, the detent pin 17 pushes the tip 25 of the plunger 24 downward to try to move downward, but the downward movement is blocked. When the brake pedal 22 is stepped on, the plunger 24 is retracted by the operation of the solenoid 26 and the tip 25 is disengaged from the detent pin 17. As a result, the downward movement of the detent pin 17 is allowed, and the detent pin 17 is separated from the pattern 14a of the detent plate 13, whereby the select lever 11 can be rotated around the rotation mechanism portion 12 in the direction of the arrow B in the drawing. You will be able to select from the parking range to another range.

Since the select lever device having such a shift lock mechanism can perform a shift change only while depressing the brake pedal 22, the driver is encouraged to perform an accurate driving without sudden start. Therefore, sudden start can be surely prevented.

When the brake pedal is depressed while the push button (not shown) of the select lever 11 is pressed, the plunger 24 moves in the detaching direction while the plunger 24 is pressed against the detent pin 17. At this time, since the tip end 25 of the plunger 24 is the tapered portion 25a (inclined surface), a force in the detaching direction acts on the plunger 24 and even if the plunger 24 is pressed against the detent pin 17,
The immersive movement of can be done without difficulty. Therefore, even if the brake pedal is stepped on while the push button is being pressed, the plunger 24 is easily disengaged from the detent pin 17, and the detent pin 17, the plunger 24, the solenoid 26, etc. are not damaged. The force when the plunger 24 is disengaged can be arbitrarily set by variously setting the inclination angle β of the tapered portion 25a. When the push button (not shown) of the select lever 11 is pressed with an excessive force without stepping on the brake pedal 22, that is, the detent pin 17 is forcibly moved downward while the detent pin 17 cannot be moved downward by the plunger 24. In this case, since the tip end of the plunger 24 is the tapered portion 25a, a force in the detaching direction acts on the plunger 24 so that the plunger 24 detaches from the detent pin 17. However, since the tip end portion of the plunger 24 is a cylindrical straight portion 25b, the straight portion 25b
Engages with the detent pin 17 and is prevented from coming off.

The above-described vehicle select lever device cannot shift the select lever 11 unless the brake pedal 22 is depressed. In addition, since most of the components can be collectively provided on the installation plate 16, a large space is not required for mounting the shift lock mechanism 30. Further, even if the brake pedal 22 is depressed with the push button of the select lever 11 pressed,
The plunger 24 is easily disengaged from the detent pin 17. Further, when the push button is accidentally pressed with an excessive force, the straight portion 25b is locked to the detent pin 17 and the plunger 24 can be prevented from coming off.

<Effect of device> The select lever device of the vehicle of the present invention is provided with a shift lock mechanism, and the shift lock mechanism shifts from the parking range unless the plunger of the drive device locks the detent pin and depresses the brake pedal. Therefore, it is possible to encourage the driver to drive accurately and to prevent the sudden start of the vehicle. Also, since the plunger and detent pin are locked via the inclined surface, even if the brake pedal is depressed with the detent pin being pushed up and down by pushing the detent pin up and down, the plunger can be easily disengaged. There is no risk of damage. Further, even if the detent pin is accidentally moved up and down with an excessive force, the tip of the plunger is locked to the detent pin, and the detachment of the plunger and the detent pin can be prevented.
