Abstract

PROBLEM TO BE SOLVED: To accomplish both of excellent key operability and high reliability as a key interlocking device by moving a block body to the position, in which an oscillating member is prevented from oscillating from the second position to the first position, when a shift lever is shifted to the position other than a parking position. SOLUTION: When a shift lever is operated from a P range to another range, a block body 21 inside a case member 11 is positioned in the intermediate position of a housing unit 17 so as to be stopped. In this process, the block body 21 crosses above an extrusion space part for one end part 16a in an oscillation member 16 so as to be stopped. As a result, the one end part 16a in the oscillation member 16 is brought into contact with the block body 21, and the oscillation member 16 is prevented from oscillating from the second position to the first position. In this way, an ignition key cannot be turned to the locking position, in which the key can be pulled out, when the shift lever is shifted to the position other than a parking position, so that the key is prevented from being pulled out.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key interlock device for a vehicle with an automatic transmission, that is, to prevent the starting key from being pulled out when the driver gets off the vehicle unless the shift lever of the automatic transmission is shifted to the parking position. The present invention relates to a key interlock device.

[0002]

2. Description of the Related Art In recent years, a vehicle equipped with an automatic transmission is provided with a key interlock device which prevents a start key from being removed unless the shift lever of the automatic transmission is shifted to a parking position when getting off the vehicle. is there.

[0003] For example, Japanese Patent Application Laid-Open No. 60-135352, Japanese Utility Model Application Laid-Open No. 1-93161, and Japanese Patent Application Laid-Open No. 64-1067 disclose such a key interlock device.
One disclosed in Japanese Patent Application Publication No. 54-54 is known.

[0004] Of these publications, Japanese Patent Application Laid-Open No. Sho 60-135
352 discloses a key interlock device, as shown in FIGS. 10 and 11, a case c formed on a steering column b in which a steering shaft a is fitted.
And a cam f that is rotatably supported in the case c and is rotated via a rotating body in a key cylinder e in accordance with a rotation operation of a start key d, and is slidable on a steering column b. A lock pin h that is supported and urged into engagement with the cam f via a return spring g is supported by the steering column b so as to be slidable in a direction orthogonal to the lock pin h. When the shift lever is at the parking position and the sliding plate j having the pin hole i that can be engaged, the sliding plate j is moved to the engaging position where the position of the pin hole i matches the position of the lock pin h. And a cable member k that slides the sliding plate j to a non-engagement position where the position of the pin hole i is disengaged from the position of the lock pin h when it is at a position other than the parking position.

When the shift lever is in the parking position, the start key d can be turned.
When the engine is to be started, the turning operation is performed by inserting the start key d at a position where it can be removed. At this time, the cam f rotates so that its protruding portion retreats from the lock pin h, and the lock pin h is pushed back to the outside of the pin hole i of the slide plate j by the urging force of the return spring g. The plate j becomes slidable. When the shift lever is pivoted to a position other than the parking position in this state, the sliding plate j is moved by the cable member k as shown in FIGS. 12 and 13, and the pin hole i of the sliding plate j is locked. It will deviate from the engagement position with the pin h. Thus, in a state where the shift lever is pivoted to a position other than the parking position, the cam f pushes the start key d against the return spring g even if the start key d is rotated to the position where the shift key can be removed. The lock pin h comes into contact with the slide plate j, and the rotation of the key d is prevented. As a result, when getting off the vehicle, the start key cannot be removed unless the shift lever is shifted to the parking position.

[0006]

However, in the above-mentioned key interlock device, the slide pin is pushed out by pushing the lock pin h against the urging force of the return spring g due to the advance of the projection of the cam f. j to the pin hole i, and the protrusion of the cam f retracts to lock the lock pin h by the urging force of the return spring g.
In order to ensure that the lock pin h comes out of the pin hole i of the sliding plate j when the protrusion of the cam f is retracted, the following structure is adopted. It is necessary to increase the urging force of the return spring g. In this case, the return spring g having a larger biasing force is used because the variation in the biasing force at the time of manufacturing the return spring g and the decrease in the biasing force due to use must be taken into consideration. When the urging force of the return spring g is increased as described above, the start key d is rotated, and the lock pin h is rotated by the cam f.
When the key is pushed out against the force of the return spring g to be engaged with the pin hole i of the sliding plate j, a strong operation force is required, and the operability of the key d is deteriorated.

In addition, when a return spring g is used, if foreign matter gets caught in the spring g, the function of pushing back the lock pin h by the spring g is hindered, and the original function of the key interlock cannot be obtained. Had.

In view of the above, the present invention addresses the above-mentioned disadvantages of the conventional key interlock device, and makes it possible to lighten the operation of the key and to move the member for restricting the rotation of the key to the restricting position. An object of the present invention is to ensure both good operability of a key and high reliability as a key interlock device so that the key interlock device can be operated reliably.

[0009]

Means for Solving the Problems To solve the above problems, the present invention is characterized by using the following means.

First, the invention described in claim 1 of the present application (hereinafter, referred to as "first invention") comprises a key operating section in which a start key is turned to a plurality of turning positions by a key operation of a driver;
The rotation member is rotated in accordance with the rotation operation of the start key, and is operated in conjunction with the shift lever of the automatic transmission being swung to a parking position and a position other than the parking position, and the shift lever is parked. A restricting means for allowing rotation of the rotating member when the shift key is shifted to a position, and preventing rotation of the start key to a position where the start key can be extracted when the shift lever is shifted to a position other than the parking position. A key interlock device for a vehicle with an automatic transmission, wherein the turning member is included in a case member that supports the key operation section on a steering column, and the turning member is rotated with the turning operation of the start key. In addition to the first and second cam portions that rotate integrally, the restricting means includes an end portion connected to the first cam portion,
The other end portion is swingably supported by the case member in a state of straddling the two cam portions so as to be in contact with the second cam portion, respectively, and when the start key is at a position where the start key can be removed, the first When the cam is in a first position in which one end is pushed out and the start key is in a position where it cannot be removed, the swinging position is changed to a second position in which the other end is pushed out by the second cam. A movable member and a cable member that moves in the axial direction along with the swing of the shift lever, and is in a regulation release position that allows the swing member to swing when the shift lever is shifted to the parking position. A swing regulating member that moves to a position that regulates the swing of the swing member from the second position to the first position when the shift lever is shifted to a position other than the parking position. It is characterized by.

According to a second aspect of the present invention (hereinafter referred to as a "second invention"), when the swing member is in the first position, the swing regulating member is connected to the regulating member. Abuts on the swing member on the moving path of the first member, thereby restricting the movement of the cable member and prohibiting the shift lever from swinging from the parking position to another swing position. When the swing control member is released from contact with the swing member on the movement path, the movement restriction of the cable member is released and the shift lever is moved from the parking position to a position other than the parking position. Characterized in that it is configured to allow swinging.

Further, the invention according to claim 3 (hereinafter referred to as "the invention")
According to the "third invention", in the second invention, the movement path of the swing regulating member is provided so as to be oblique to the longitudinal direction of the swing member, and the swing regulating member and the swing regulating member The contact surface of the moving member is formed so as to be parallel to each other in a direction perpendicular to the movement path.

By using the above means, the following effects can be obtained according to the inventions of the present application.

First, in any of the first to third aspects of the present invention, when the start key is rotated to start the engine, for example, in a state where the shift lever is shifted to the parking position, the start key is rotated. The first and second cam portions as rotating members that rotate with the rotation are rotated in the same direction, and the swing member is pushed at its one end by the first cam portion by the rotation of these cam portions. From the first posture, the second cam portion swings to the second posture in which the other end is pushed out. When the shift lever is operated to swing to a position other than the parking position in the state of the second posture, the swing regulating member moves to the position for regulating the swing of the swing member by the cable member,
The rotation of the first and second cam portions to a position where the start key can be removed cannot be performed. Thus, when the shift lever is shifted to a position other than the parking position, the start key cannot be rotated to a position where the start key can be extracted, and the key is prevented from being extracted.

Further, when the shift lever is operated to swing from a position other than the parking position to the parking position, the swing regulating member is moved by the cable member to a position where the swing regulation of the swing member is released. The rotation of the first and second cam portions becomes possible.
Therefore, since the key operation section can be rotated, if the start key is rotated to return to a position where it can be removed, the swing member is moved from the second posture by the first and second cam portions. By swinging to the first position, the key can be returned to a position where it can be extracted.

As described above, not only when the start key is rotated to a position where the engine can be started, but also when the start key is returned to a position where the start key can be removed, the swinging member is formed by the first and second cam portions. Can be swung directly, so that there is no need to rotate the start key against the return spring as in the prior art, and the swinging member can be reliably swung with a small operating force. .

According to the second invention, when the swing member is in the first position, the movement of the cable member is regulated by the swing regulating member abutting on the swing member on its movement path. When the shift lever is prohibited from swinging from the parking position to another swing position, and the swing member is in the second posture,
Since the contact of the swing restricting member with the swing member on the movement path is released to allow the shift lever to swing from the parking position to a position other than the parking position, the starting If the key is operated to the position where the key cannot be removed, swinging of the shift lever from the parking position to a position other than the parking position is prohibited. As a result, when the vehicle is stopped on a slope or the like, the shift lever does not move due to careless operation from the parking position to the traveling position.

According to the third aspect of the present invention, when the movement path of the swing regulating member is obliquely oblique to the longitudinal direction of the swing member, the contact surface between the swing regulating member and the swing member can be changed. By being formed so as to be parallel to each other in a direction perpendicular to the movement path, when the swinging member is in the first posture, both members abut on surfaces parallel to each other. Thus, it is possible to prevent the corner of one member from contacting the contact surface of the other member and the contact portion from being locally damaged.

[0019]

A swing member 16 is swingably supported by the cam portion 14 via a pivot 16 ′ in a state of straddling the two cam portions such that the other end thereof is in contact with the second cam portion 15. And
When the start key 3 is turned to the Lock position, one end portion 16a of the swing member 16 is pushed out by the first cam portion 14 as shown in FIGS. While the start key 3 is moved from the Lock position to the Acc position or to the Start position.
When rotated in the position direction, as shown in FIGS. 8 and 9, the second cam portion 15 swings the other end portion 16b to the second posture in which the other end portion 16b is pushed out. An engagement protrusion 16d having a contact surface 16c is provided on the integral portion 16a of the swing member 16 so as to project therefrom.

In the center of the lower surface of the case member 11,
The case member 11 is provided with a housing portion 17 at the end of the cable 7 extending at a predetermined inclination angle, while extending parallel to the longitudinal direction of the steering column 2. As shown in FIGS. 3 to 6, the housing portion 17 is integrally provided on the lower surface of the case member 11, and is attached to the mounting member 18 from below with a hollow mounting member 18 having an open lower surface. Hollow housing member 1 with an open top
9, and the end of the cable 7 is housed in an internal space formed by the mounting member 18 and the housing member 19. The mounting member 18 includes an upper surface 18a and walls 18b, 18 extending downward from both side edges of the upper surface 18a.
b, the middle portion in the longitudinal direction of the upper surface portion 18a is divided and arranged on both sides with the opening 11a interposed therebetween, and a through hole 18c is provided at the end on the driver's seat side. . Further, the wall portions 18b, 18b on the engine room side are expanded in the width direction.
A notch 18d having substantially the same width as the width of the b, 18b is provided,
An engagement recess 18e is formed on the outer surface of the end surface around the notch 18d.

On the other hand, the housing member 19 has a flat lower surface 19a.
A wall 19b extending upward from an edge of the lower surface 19a;
19b, and from the end on the driver's seat side, the mounting member 1
8 are provided with claw portions 19c that engage with the through holes 18c. Further, on both sides of a portion near the end on the engine room side, a concave portion 19d which extends in the up-down direction and fits with the notch 18d on the end surface of the mounting member 18 is formed. The end of the cable 7 is attached to the side end by fitting.

In the housing member 19, a portion on the driver's seat side from above the opening 11a straddles the outside of the mounting member 18, and a portion closer to the engine room than the opening 11a is an extended portion of the mounting member 18. It is assembled so that it goes inside the. In this case, with the engine room side recess 19d of the housing member 19 being fitted into the engagement recess 18e of the mounting member 18, the housing member 19 is moved to the driver's seat side, and the claw portion 19c passes through the mounting member 18. Hole 1
8c, and thereafter, a clip 20 having a leaf spring portion for applying a biasing force in the driver's seat direction is attached to the inner surface of the extended side end of the mounting member 18 and the concave portion 19 of the housing member 19.
d, the housing member 19 is urged toward the driver's seat with respect to the mounting member 18 to be fixed.

On the other hand, the cable 7 has an outer cable 7a and an inner cable 7b movable within the outer cable 7a as shown in FIGS. 3 and 4, and a mounting member 7c is attached to the end of the outer cable 7a. The end of the cable 7 is entirely fitted to the engine room side end of the housing member 19 via the mounting member 7c. A block 21 having a substantially rectangular parallelepiped shape is connected to the distal end of the inner cable 7b.
Move in the longitudinal direction of the housing portion 17 while being sandwiched between the upper surface of the housing member 19 and the lower surface of the housing member 19.

Then, as described above, when the shift lever 5 is in the P range, the shift button 5b is pushed, whereby the shift pin 5c moves down and the inner cable 7b moves in the direction of arrow C. 7, the push operation of the shift button 5b is released while the shift button 5b is released, whereby the shift pin 5c is moved upward and the inner cable 7b is moved in the direction of the arrow D.
When it moves in the direction, as shown in FIG. 4, it is located at the driver's seat side end of the housing portion 17.

In this case, when the swing member 16 is in the first position, the block body 21 abuts on the contact surface 16c of the engagement protrusion 16d of the one end 16a of the swing member 16 on its movement path. By contact, the movement of the cable 7 is restricted, and the swing of the shift lever 5 from the P range to another range is prohibited. When the swing member 16 is in the second posture, the block body 21 is closed. Of the swing member 16 on the moving path is released from the end 16a,
The restriction on the movement of the cable 7 is released and the P
Swing from one range to another range is allowed. In this case, even if the moving path of the block body 21 is provided so as to be oblique to the longitudinal direction of the swinging member 16, the block is so arranged that the two members 16 and 21 abut on parallel surfaces. The contact surface 21a of the body 21 and the contact surface 16c of the swing member 16 are formed so as to be parallel to each other in a direction orthogonal to the movement path.

Next, the operation of the key interlock device with the shift lock will be described.

Now, it is assumed that the vehicle is stopped and the engine is to be started. At this time, the shift lever 5
Is in the P range position, and the key cylinder 12 is in a state where the starting key 3 is turned to the Lock position and pulled out. Therefore, the cable 7 is moving in the D direction,
The block 21 connected to the end of the cable 7 guided into the case member 11 of the key operation unit 6 has moved to the driver's seat side end in the housing 17 as shown in FIG. In addition, by the rotation of the first and second cam portions 14 and 15,
The swing member 16 is in the first posture as shown in FIG.
The one end 16a extends on the movement path of the block body 21.

Therefore, even if the shift button 5b is pressed to shift the shift lever 5 from the P range to another range such as the D range in this state, the block body 21 is moved. The movement of the inner cable 7b is restricted by contacting the engagement protrusion 16d at one end 16a of the swing member 16 that has advanced on the path, and the shift operation section 6 is prevented from interlocking with the shift pin 5c of the interlocking mechanism. You. For this reason, the shift pin 5c of the shift lever 5 cannot be moved down, so that the shift lever 5 cannot be shifted from the P range to another range. As a result, it is prohibited to operate the shift lever 5 to a driving range such as the D range before starting the engine, and it is possible to prevent the vehicle from inadvertently moving when the vehicle is stopped on a slope or the like.

Next, when the start key 5 is turned to the Start position, the ignition switch is turned on to start the engine, and the first and second cam portions 14, 15 are turned with the key operation. Then, by the rotation of these cam portions 14 and 15, the swing member 16 is moved to its one end 1
6a is moved from the first posture pushed out by the first cam portion 14 to the second posture where the other end portion 16b is pushed out by the second cam portion 15, that is, the position where the one end portion 16a is retracted from the moving path of the block body 21. Be moved. However, in this state, the movement restriction of the block body 21 has not been released yet, and the cable 7 cannot be released until the brake pedal 8 is depressed.
Can be moved in the C direction. As a result, shift lever 1
Is shifted to a travel range or the like while the brake pedal 8 is depressed, and unexpected start is avoided more effectively.

When the shift lever 5 is operated from the P range to another range, the cable 7 stops moving in the direction C, and the block 21 in the case member 11 is shown in FIGS. And stops at the intermediate portion of the housing portion 17. At this time, the block body 21 is
Stop across the extrusion space of one end 16a of
As a result, the abutment between the one end 16a of the swing member 16 and the block body 21 prevents the swing member 16 from swinging from the second posture to the first posture. Thus, when the shift lever 5 is shifted to a position other than the parking position, the start key 3 cannot be rotated to the lock position where the key 3 can be extracted, and the key 3 is prevented from being extracted. .

On the other hand, when the shift lever 5 is operated to swing from a position other than the P range to the P range, the block 16 is moved by the movement of the cable 7 as shown in FIG.
6 is moved to the position where the swing regulation is released. This allows
The first and second cam portions 14 and 15 can be turned, and the start key 3 can be turned to a position where it can be removed.

When the block 21 and the swing member 16 are in contact with each other during the shift lock, the contact surface 21a of the block 21 and the contact surface 16c of the swing member 16 are moved along the path of the block 21. Are formed so as to be parallel to each other in a direction orthogonal to the contact surface 16.
As in the case where the c and 21a are not provided, the problem that the contact force acts intensively on one point of the corner and damages the other member is avoided.

In the embodiment shown in the drawings, the rotating shaft 13 and the pair of first and second cam portions 14 and 15 are formed by integral molding, thereby reducing the number of parts. Is being planned.

[0040]

As described above, according to the key interlock device for a vehicle with an automatic transmission according to the present invention, the first and second rotating members integrally rotate with the turning operation of the start key. It has a second cam portion and is swingably supported in a state of straddling the two cam portions so that one end portion is in contact with the first cam portion and the other end portion is in contact with the second cam portion. When the start key is at the position where it can be removed, the first cam portion is in a first posture in which one end is pushed out. A swing member swinging to the second posture in which the end is pushed out, and a cable member moving in the axial direction with the swing of the shift lever, wherein the shift lever is shifted to the parking position. Release position that allows swinging of the swinging member when And when the shift lever is shifted to a position other than the parking position, a swing regulating member that is moved to a position that regulates the swing of the swing member from the second position to the first position. Since there is provided a restricting means provided with a key interlock function to prevent the start key from being removed when the shift lever of the automatic transmission is shifted to the parking position when getting off the vehicle, The first and second keys are not only used when rotating the engine from a position where the engine can be extracted to, for example, a position where the engine can be started, but also when returning the start key to a position where the engine can be extracted.
Since the swinging member can be directly swung by the cam portion, there is no need to rotate the start key against the return spring as in the related art, and the swinging member can be swung with a light operating force. It can be done reliably.

In addition, even if foreign matter may be caught between the first and second cam portions and the swinging member, the first and second cam portions are brought into engagement by the start key. By rotating the first and second cam portions and the swinging member against each other, the foreign matter having a relatively low rigidity, such as the first and second cam portions and the swing member, is deformed or destroyed to remove the foreign matter. This makes it possible to reduce the occurrence of a situation in which the push-back function is easily hindered, as in the case of using a return spring, and the rotation of the start key to a position where it can be removed cannot be prevented. Performance can be improved.

When the swing member is in the first position, the swing regulating member abuts the swing member on its movement path, so that the shift lever restricts the movement of the cable member from the parking position of the shift lever. When the swing member is in the second position, the contact of the swing restricting member with the swing member on the movement path is released, and the shift is performed. Since the lever is allowed to swing from the parking position to a position other than the parking position, if the start key is operated to the position where it cannot be removed, the shift lever can be moved from the parking position to a position other than the parking position. Swing will be prohibited. As a result, when the vehicle is stopped on a slope or the like, the shift lever does not move due to careless operation from the parking position to the traveling position.

Further, when the movement path of the swing regulating member is oblique to the longitudinal direction of the swing member, the contact surface between the swing regulating member and the swing member is perpendicular to the movement path. Are formed so as to be parallel to each other, so that when the swinging member is in the first position, the two members abut on surfaces parallel to each other. Thus, it is possible to prevent the corner of one member from contacting the contact surface of the other member and the contact portion from being locally damaged.
