Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a shift lever locking device that prevents the shift lever from being shifted from a parking range to another range unless predetermined conditions are met.

(Prior Art) Conventionally, as a locking device for a shift lever, one disclosed in, for example, Japanese Patent Laid-Open No. 135352/1983 is known.

This conventional device has a bell crank connected to the key rotor of the cylinder lock by a cable on the position plate, and the position pin engages with this bell crank when the shift lever is in the parking range. .

That is, an engagement groove is formed in the bell crank, and this engagement groove is released in the direction of the travel range of the shift lever, so that the position pin can move to the lower disengagement position (without engaging the position groove and move the shift lever). The position pin can engage and disengage from the engagement groove when the position pin is in the upper engagement position (the position that allows shifting of the shift lever). When it is in the position that restricts shifting), it cannot be disengaged.

Further, the bell crank is urged to rotate downward by a return spring.

Therefore, when the vehicle is shifted to the parking range, the position pin engages with the bell crank and then slides upward due to the biasing force that biases the position pin to slide upward. In conjunction with the upward slide of the position pin, the bell crank rotates upward against the biasing force of the return spring. When the bell crank and the position pin are engaged in this way, if the rotation of the bell crank is restricted by operating the cylinder lock, the downward slide of the position pin is restricted, and the position is shifted from the parking range to the driving range. I won't be able to do that.

(Problems to be Solved by the Invention) However, in the conventional device described above, the position pin rotates the bell crank against the biasing force of the return spring after engaging with the bell crank. In order to rotate the position pin to the engagement position, it is necessary to increase the urging force that urges the position pin to slide upward by an amount that resists this urging force.

Therefore, during normal operation of the shift lever, the operating force required to slide the position pin downward increases, resulting in a problem that operability deteriorates.

The present invention has been made in view of the above-mentioned problem, and although it has a structure in which the lock body is moved against the biasing force of the return spring when shifted to the parking range, the operating force during normal operation does not become large. It is an object of the present invention to provide a shift lever locking device that does the following.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the shift lever locking device of the present invention includes a first biasing device that biases the position pin to slide upward during normal operation. A second biasing means for applying biasing force to the lock body is provided at the same time.

That is, in the shift lever locking device of the present invention, the position pin engages with the position groove of the position plate to restrict shifting, and the disengaged position allows the shift lever to be shifted. The lock body is provided so as to be slidable in the direction of the engagement position by the first biasing means, and the lock body engages with and disengages from the position pin at the disengagement position in the parking range of the shift lever on the vehicle body side. The lock body is movable between an unlock position where the shift lever can be shifted to another range and a lock position where the shift lever cannot be shifted from the parking range to the other range by engaging with a position pin at the engagement position. In a shift lever locking device connected to a cylinder lock of a starting key so that the engine starting key can be inserted and removed only when the shift lever is in the locked position, when the shift lever is shifted to the parking range, the lock body is moved to the locked position. A second biasing means is provided which applies a biasing force in the direction of movement of the lock position.

In providing the second biasing means, the second biasing means is provided on the shift lever and is arranged so as to press the lock body toward the lock position when the shift lever is shifted to the parking range. Good too.

Further, the second biasing means is provided on the vehicle body side, and a first movable body and a second movable body biased in opposite directions by the second biasing means are provided on the vehicle body side, One of the two movable bodies is arranged to be able to press the lock body in the lock position direction, and the other of the two movable bodies is biased by the second biasing means by the shift lever when the shift lever is shifted to the parking range. It may be arranged so that it is pressed in the opposite direction.

Further, a second biasing means is attached to the lock body, and the second biasing means presses the shift lever in a direction in which it comes into contact with the shift lever and rotates to the lock position when the shift lever is shifted to the parking range. It may be arranged so that

(Operation) When the shift lever is shifted from another range to the parking range, the second biasing means moves the lock body from the unlocked position to the locked position. In conjunction with this movement of the lock body, the position pin slides from the disengaged position to the engaged position by a force obtained by adding the biasing force of the second biasing unit to the biasing force of the first biasing unit. be.

In this case, in the invention as claimed in claim 2, the second biasing means is provided on the shift lever, and when the shift lever is shifted to the parking range, the movable body contacts the lock body, and the second biasing means is provided in the shift lever.
The urging force of the urging means is inputted from the movable body in a direction to move the locking body to the locking position.

Further, in the invention according to claim 3, the shift lever presses one of the first and second movable bodies provided on the vehicle body side to move the shift lever in a direction opposite to the biasing direction of the second biasing means, The biasing force generated by the second biasing means based on the movement of one movable body is input to the other movable body, and is also input to the lock body via the other movable body. This moves the lock body to the lock position.

Further, in the invention described in claim 4, the shift lever pushes the second biasing means of the lock body toward the lock position. As a result, the second biasing means is deformed, and the resulting elastic force acts on the lock body in the direction of the lock position.

Then, when the lock body is placed in the lock position as described above and the lock body is fixed in that position based on the key operation of the cylinder lock, the slide of the position pin toward the disengagement position is regulated. This restricts shifting from the parking range.

Next, when shifting the shift lever from the parking range to another range, the cylinder lock is first operated to unlock the lock body so that the lock body can be moved to the unlocked position.

Then, when an operating force is applied to the position pin in a direction that resists the biasing forces of the first and second biasing means and the position pin is slid toward the disengaged position, the lock body is
The vehicle can be moved to the unlocked position and shifted from the parking range to other ranges.

Also, when shifting outside the parking range like this,
Since only the force required to resist the biasing force of the first biasing means against the position pin is required, the operating force can be small.

(Example) Embodiments of the present invention will be described below based on the drawings.

First, the configuration will be explained.

FIG. 1 is a perspective view showing a shift lever lip device according to a first embodiment of the present invention corresponding to the invention as claimed in claim 2, and numeral 1 in the figure indicates the shift lever.

This shift lever 1 is supported by the vehicle body so as to be able to swing around a rotating shaft 11, and can be shifted to a parking range P, a reverse range R, a neutral range N, a drive range D, a 2nd speed range ■, and a 1st speed range ■. is formed. In this specification, ranges other than the parking range P will be collectively referred to as the driving range.

This shift lever 1 is provided with a position pin 12 that can be slid up and down along a slide groove 13.
That is, the engagement position (upper slide position) where the shift is restricted by engaging with the position groove 21 formed in the position plate 2 provided on the side of the shift lever 1, and the restriction release position (lower slide position) where the shift restriction is released. position).

Further, the position pin 12 is slidably biased in the direction of the engagement position by a spring serving as a first biasing means (not shown) provided in the shift lever 1, and is provided in the upper part of the shift lever 1. By pressing the push button 15, the position pin 12 can be slid to the disengaged position against this biasing force.

Next, reference numeral 3 denotes a lock body, which is formed in an L-shape, whose central part is rotatably supported by the position plate 2, and whose one end 35 is connected to a cylinder lock 8, which will be described later, via a cable 7. The other end 36 can engage with the lower side of the position bin 12.

That is, as shown in FIGS. 1 and 3, the lock body 3 has the other end 3
6 is in contact with the lower stopper 34, from the unlocked position, which is a position where the shift lever 1 can be engaged with and disengaged from the disengaged position of the position bin 12 when the shift lever 1 is shifted to the parking range P. As shown in Figure 2, the other end 36
is rotatable within a range up to the lock position where the pin 12 is engaged with the position bin 12 in the engagement position.

This lock body 3 is provided with a return spring 37 that rotationally biases the lock body 3 toward the unlock position.

The cylinder lock 8 is, for example, disclosed in Japanese Patent Application Laid-Open No. 63-12155.
The structure described in Publication No. 1 is used, and as shown in Figures 2 and 3, an engine start key (not shown) is inserted into the cylinder case 82 and turned to start the engine. A key rotor 83 that is moved is provided.

This key rotor 83 is moved to lock position LK and accessory position ACC by operating the engine start key.
It can be rotated to four positions: , ON position, and start position S, and in conjunction with this rotation, the ignition switch (not shown), which is provided integrally with the key rotor 83, can be switched. It is now possible to do so.

Note that the lock position LK is a position in which the engine start key can be inserted and removed, the ignition switch is turned OFF, and the steering is locked. Accessory position ACC is a position in which the engine is stopped but electrical components can be used. On position ON
is the position where the engine can be driven. The start position ST is a position where driving of the engine is started.

In addition, FIG. 2 shows the key rotor 83 in the lock position LK.
Figure 3 shows the on position.
It shows the state where it has rotated.

The stopper 81 is rotatably supported by the cylinder case 82 around a pin 811, and when the lock body 3 is in the unlocked position (FIG. 3), the stopper 81 is attached to the cable 7. In this position, the claw portion 84 of the stopper 81 engages with the protrusion 85 formed on the key rotor 83, and the key rotor 83 rotates from the accessory position ACC to the lock position LK. Regulate what you do.

On the other hand, when the lock body 3 is in the locked position (FIG. 21), the stopper 81 is pushed by the cable γ and placed in the unlocked position, and in this position, the claw portion 8 of the stopper 81
4 moves to the outside of the cylinder case 82 and attaches to the protrusion 85.
The key rotor 83 is disposed in a position where it does not engage with the key rotor 83, and the key rotor 83 can be rotated to the lock position LK.

Further, the projection 85 of the key rotor 83 is arranged at a position corresponding to the tip of the claw 84 of the stopper 81 when the key rotor 83 is in the lock position L, and prevents the stopper 81 from rotating to the lock position shown in FIG. regulate.

The shift lever 1 is provided with a movable body 4.

This movable body 4 has a shift lever inside a cylindrical case 41.
It is supported so as to be slidable in one swinging direction, and is biased in the projecting direction by a spring 42 serving as a second biasing means.

The movable body 4 is arranged so as to press one end 35 of the lock body 3 in a direction to rotate it to the lock position when the shift lever 1 is shifted to the parking range P.

The biasing force of the spring 42 is set so that the moment applied to the lock body 3 via the movable body 4 is greater than the moment applied to the lock body 3 by the return spring 37.

Next, the operation of the embodiment will be explained.

(a) When parking (locked state) When parking with the shift lever 1 in the parking range P and the engine start key removed from the cylinder lock 8, the lock body 3 is placed in the locked position as shown in Fig. 2. In addition, in the cylinder lock 8, the key rotor 83 is in the lock position LK, so that the protrusion 85 of the key rotor 83 restricts the rotation of the stopper 81 in the direction of the lock position and prevents the cable 7 from being pulled. It is now impossible to do so.

Therefore, the lock body 3 is in a fixed state at the lock position.

Therefore, if you try to slide the position bin 12 downward in order to perform a parking release operation of the shift lever 1 in this state, the position bin 12 will come into contact with the lock body 3 and will not slide downward to the disengaged position. Therefore, it is not possible to shift from the parking range P to the driving range.

(b) When the vehicle starts traveling, first insert the engine start key into the cylinder lock 8 and rotate the key rotor 83 toward the ON position. As a result, the stopper 8
The rotation restriction for 1 is released, and the cable Y can be pulled.

Therefore, when the push button 15 is pressed to slide the position bin 12 downward, the lock body 3 is also rotated toward the unlocked position in conjunction with this.

In this case, the operating force includes a biasing force of a first biasing means (spring) that biases the position bin 12 upward (not shown), and a second biasing force that biases the movable body 4. The required force is the sum of the biasing force of the spring 42 and the biasing force of the return spring 37.

(C) When driving When the shift lever 1 is shifted to the driving range and driving, only the urging force of the first urging means (spring, not shown) acts on the position bin 12. , it is sufficient to apply an operating force to the push button 15 such that a force exceeding this urging force acts on the position bin 12.

Further, in this case, since the lock body 3 is placed in the unlocked position as shown in FIG. 3, the stopper 81 of the cylinder lock 8 is placed in the locked position.

Therefore, by rotating the engine start key, the key rotor 8
3 from the ON position ON side to the lock position LK, the protrusion 85 of the key rotor 83
engages with the claw portion 84 and cannot be rotated from the accessory position ACC to the lock position LK side.

Therefore, although the engine can be stopped, the lock position LK prevents the engine start key from being removed.

(d) At the time of reparking In the driving state as described above, even if the engine start key is rotated toward the lock position LK, the rotation is restricted at the accessory position ACC.

Therefore, in order to remove the engine start key from this state, the shift lever 1 is shifted to the parking range P.

Then, the position pin 12 is placed above the other end 36 of the lock body 3, and the movable body 4 is placed above the other end 35 of the lock body 3.
is pressed, and the elastic force of the spring 42 is input to one end of the lock body 3 by the amount that the spring 42 is shortened by the reaction force of this pressing force. Therefore, the position pin 72 slides to the engagement position due to the biasing force of the first biasing means (spring, not shown), and the lock body 3 is rotated toward the lock position due to the biasing force of the spring 42.

When the lock body 3 rotates to the lock position, the stopper 81 moves to the unlock position, making it possible to rotate the key rotor 83 to the lock position LK. Therefore, the key rotor 83 is rotated to the lock position LK, and the above-mentioned parking state is achieved.

As explained above, in the shift lever locking device according to the embodiment of the present invention, the biasing force of the spring 42 acts against the return spring 37 when the lock body 3 is rotated from the unlocked position to the locked position. Although the structure is such that the lock body 3 can be reliably moved to the lock position, the biasing force of the spring 42 does not act on the position pin 12 in the driving range, so the operating force does not increase. , the effect of good operability can be obtained.

Next, another embodiment will be described. In describing the other embodiments, the same components as in the first embodiment will be given the same reference numerals as in the first embodiment, and the explanation will be omitted, and only the differences will be explained. Also, regarding the operation, only the differences from the first embodiment will be explained.

4 and 5 are side views showing essential parts of a device according to a second embodiment of the present invention corresponding to the invention of claim 3.
4 indicates the case.

This case 244 is formed into a cylindrical shape and is disposed with the center of attention facing substantially in the direction in which the shift lever 1 swings.

Inside the case 244, there are a first movable body 241 and a second movable body 241.
A movable body 242 is provided so as to be slidable in the axial direction, and a spring 243 serving as a second biasing means is provided between both the movable bodies 241 and 242.

Moreover, this spring 203 is connected to both movable bodies 241.24.
When one of the movable bodies 241 and 242 protrudes from the case 244, it is not shortened much and both movable bodies 241 and 242 are attached to the case 244.
4 and shortened to a length such that a biasing force acts on both movable bodies 241 and 242.

Further, the shift lever 1 is provided with a pressing bracket 211 at a position facing the second movable body 242.

Therefore, as shown in FIG. 4, when the lock body 3 is placed in the unlocked position by the biasing force of the return spring 37, the first movable body 241 is placed in the position retracted into the case 244, and on the other hand, The second movable body 242 is the case 2
It is in a state of protruding from 44.

At this time, the biasing force acting on the movable bodies 241 and 242 is small, and the lock body 3 is not rotated in the direction of the lock position.

Next, when shift lever 1 is shifted to parking range P,
The pressing bracket 211 presses the second movable body 242 into the case 244, thereby causing the spring 24
3 is shortened, the biasing force against both movable bodies 241 and 242 increases, the first movable body 241 protrudes from the case 244, and the lock body 3 is moved to the lock position.

When shifting the shift lever 1 from the parking range P, the biasing force of the first biasing means (not shown) and the biasing force of the spring 243 are added to the position pin 12, and then the biasing force of the return spring 37 is applied. By applying the operating force minus the force, the lock body 3 can be rotated to the unlock position.

Next, FIG. 6 shows the third aspect of the present invention corresponding to the invention of claim 3.
7 is a side view showing the main parts of the embodiment device, and FIG. 7 is a view taken in the direction of arrow A in FIG. It is installed protrudingly.

Further, in the figure, 341 indicates a first movable body, and 342 indicates a second movable body. Both movable bodies 341 and 342 are rotatably provided around a pin 343, and between both movable bodies 341 and 342. is provided with a spring 344 that acts to push back when both rotate in the expansion direction.

In addition, 311 is the same pressing bracket as in the second embodiment, and 34
5 is a stopper.

Therefore, when the shift lever 1 is shifted to the parking range P, the pressing bracket 311 presses the second movable body 342, thereby generating a biasing force in the spring 344, and this biasing force is applied to the first movable body 341 to lock the spring 344. It acts to rotate the body 3 to the lock position.

Next, FIG. 8 shows the fourth aspect of the present invention corresponding to the invention of claim 4.
It is a side view showing the essential parts of the embodiment device, in which reference numeral 442 indicates a leaf spring, and 411 indicates a pressing bracket similar to the second embodiment.

One end of this plate spring 442 is fixed to the lock body 3, and the other end is arranged on the movement trajectory of the pressing bracket 411 when shifting the shift lever 1 to the parking range P.

Therefore, when the shift lever 1 is shifted to the parking range P, the pressing bracket 411 pushes the other end of the leaf spring 442 and is elastically deformed, and the resulting biasing force acts in the direction of rotating the locking body 3 to the locking position. .

Although the embodiment has been described above based on the drawings, the specific configuration is not limited to this embodiment. For example, in the embodiment, one end is simply arranged below the position pin as a lock body. , a type that is engaged when the position pin slides downward is shown, but a structure that has an engagement groove or the like and is engaged when the position pin slides up and down may also be used.

(Effects of the Invention) As explained above, in the shift lever locking device of the present invention, when the shift lever is shifted to the parking range, the first actuator applies an urging force to the lock body in the lock position movement direction. Since the second biasing means is provided, when the shift lever is shifted to the parking range, the biasing force of the second biasing means is input to the lock body, and the lock body is activated by the return spring. Although it has a structure that can be rotated toward the lock position against force, when operating the position pin in ranges other than parking range,
This requires only an operating force to resist the biasing force of the first biasing means against the position pin, so that in the parking range, by obtaining the biasing force of the second biasing means,
Although reliable operation can be performed with a high biasing force, the operating force of the position pin when shifting to a position other than the parking range is small, and high operability can be achieved.
