[0003]
[Problems to be solved by the invention]
However, the conventional shift lock device has the following problems (problems).
{Circle around (1)} Since the movement of the shift interlock member is linear sliding, if it is tilted, it will come into contact with an angle, increasing the sliding resistance and possibly causing malfunction. If the sliding clearance is made small so as not to tilt, the accuracy must be increased and the cost is increased.
{Circle around (2)} In the case of linear sliding, it is necessary to protrude into the concave portion provided in the shift interlock member. Increasing accuracy adds cost.
A first object of the present invention is to provide a shift lock device that can reduce the sliding resistance of a shift interlock member as compared with the related art.

[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
A shift lock device 10 according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the shift lock device 10 includes a shift interlock member 20 to which a shift interlock cable 11 is connected, a key interlock member 30 to which a key interlock cable 12 is connected, a brake pedal or the brake pedal. It has a brake interlock member 40 with which a member (hereinafter, referred to as a brake pedal) 13 interlocked with the pedal can abut.
The shift interlock member 20, the key interlock member 30, and the brake interlock member 40 are supported by a casing 50.
[0007]
The shift interlock member 20 has both ends and a shift interlock rotation bearing 21 at an intermediate portion. The cross-sectional shape of the shift interlock member 20 is rectangular. The shift interlock member 20 is attached to the casing 50 at a shift interlock rotation bearing 21 so as to be rotatable and slidable around the shift interlock rotation shaft 21a.
The shift interlock member 20 is rotatable between a shift lock position 20a that locks the shift operation of the shift lever and a shift lock release position 20b that allows the shift operation of the shift lever. When the shift lever device is a straight type shift lever device, the shift interlock member 20 is in the shift lock position 20a when the shift lever is in the P (parking) position, and the shift lever is in a position other than P. (2) When the shift lever device is a gate-type shift lever device when the shift lever device is a gate-type shift lever device, when the shift lever is at the P-free position, the shift lock position 20a and the shift lever are at positions other than the P-free position. It is set to be located at the shift lock release position 20b when in the position.
[0008]
One end of the shift interlock member 20 can move in and out of a movement locus of a key interlock boss portion 32 of the key interlock member 30 described later. At one end of the shift interlock member 20, a first contact surface 22 and a second contact surface 23 are formed. The first contact surface 22 and the second contact surface 23 are formed at different positions on the shift interlock member 20. The first contact surface 22 and the second contact surface 23 can contact the key interlock member 30.
When the shift interlock member 20 is located at the shift lock release position 20b, the first contact surface 22 enters the movement locus of a fourth contact surface 33 of the key interlock member 30 described later.
[0009]
One end of the shift interlock cable 11 is connected to the other end of the shift interlock member 20. The operation direction of the shift interlock cable 11 is orthogonal to the axial direction of the shift interlock rotation shaft 21a. The other end of the shift interlock cable 11 extends toward a shift lever (not shown), and is linked to the shift lever at the P (parking) position. However, the other end of the shift interlock cable 11 may be linked to a shift lever device other than the P position (for example, 2 (second) L (low)).
The shift interlock member 20 or the shift interlock cable 11 is spring-biased in a direction for rotating the shift interlock member 20 from the shift lock position 20a to the shift lock release position 20b. However, this spring bias is not essential.
[0010]
At the other end of the shift interlock member 20, a shift interlock boss 24 protruding from the other end toward the brake interlock member 40 in the axial direction of the shift interlock rotation shaft 21a is formed. In the shift interlock member 20, only the shift interlock boss portion 24 can enter and exit the movement locus of the brake interlock member 40. However, when the shift interlock member 20 is located at the shift lock position 20a or the shift lock release position 20b, the shift interlock boss portion 24 is at a position deviated from the movement locus of the brake interlock member 40. The shift interlock boss portion 24 has a third contact surface 25 formed thereon.
[0011]
The key interlock member 30 has a key interlock rotation bearing 31 at one end. The key interlock member 30 is attached to the casing 50 so as to be rotatable and slidable around a key interlock rotation shaft 31a by a key interlock rotation bearing portion 31. The key interlock member 30 is rotatable between a key lock release position 30a where the ignition key (not shown) can be removed and a key lock position 30b where the ignition key cannot be removed. The axial direction of the key interlock rotating shaft 31a is the same as the axial direction of the shift interlock rotating shaft 21a. The position of the key interlock rotation shaft 31a is different from the position of the shift interlock rotation shaft 21a. Except for the key interlock rotation bearing 31 and the key interlock boss 32, the rotation plane of the key interlock member 30 and the rotation plane of the shift interlock member 20, Are located in different planes in the axial direction of the key interlock rotation shaft 31a.
[0012]
The key interlock member 30 is provided with a key at a position different from the key interlock rotation shaft 31a (for example, at an end opposite to the key interlock rotation bearing 31 or at an intermediate portion of the key interlock member 30). One end of the interlock cable 12 is connected. The operation direction of the key interlock cable 12 is a direction orthogonal to the axial direction of the key interlock rotation shaft 31a. The other end of the key interlock cable 12 extends to an ignition key (not shown).
The key interlock member 30 or the key interlock cable 12 is spring-biased in a direction for rotating the key interlock member 30 from the key unlock position 30a to the key lock position 30b. However, this spring bias is not essential.
[0013]
An end of the key interlock member 30 opposite to the key interlock rotation bearing 31 has a key interlock projecting from the end toward the shift interlock member 20 in the axial direction of the key interlock rotation shaft 31a. A lock boss 32 is formed. Only the key interlock boss portion 32 of the key interlock member 30 can move in and out of the movement locus of the shift interlock member 20. The key interlock boss portion 32 has a fourth contact surface 33 and a fifth contact surface 34 formed thereon.
[0014]
The in-plane direction of the fourth contact surface 33 is a direction that can contact the first contact surface 22 when the key interlock member 30 rotates. The fourth contact surface 33 only needs to be able to contact the first contact surface 22, and the in-plane direction does not have to be orthogonal to the in-plane direction of the first contact surface 22.
[0015]
When the key interlock member 30 is located at the key lock release position 30a, the fifth contact surface 34 enters the movement locus of the second contact surface 23 of the shift interlock member 20. The in-plane direction of the fifth contact surface 34 is a direction that can contact the second contact surface 23 when the shift interlock member 20 rotates. The fifth contact surface 34 only needs to be able to contact the second contact surface 23, and the in-plane direction does not have to be orthogonal to the in-plane direction of the second contact surface 23.
[0016]
The brake interlock member 40 is supported by the casing 50 so as to be able to reciprocate (linearly move). The moving direction of the brake interlock member 40 is a direction orthogonal to the axial direction of the shift interlock member rotating shaft 21a. The brake interlock member 40 is constantly urged by a spring 41 in a direction protruding from the casing 50. However, when the brake interlock member 40 is connected to the brake pedal 13, the spring 41 is unnecessary (in the embodiment of the present invention and the illustrated example, the case where the spring 41 is used will be described). The brake interlock member 40 can abut on the brake pedal 13 at the distal end in the protruding direction.
[0017]
When the brake pedal 13 is depressed, the brake pedal 13 moves away from the brake interlock member 40, and when the brake pedal 13 is not depressed, the brake interlock member 40 resists the urging force of the spring 41 in the casing 50. Then push it. That is, when the brake pedal 13 is depressed, the brake interlock member 40 moves in a direction protruding from the casing 50 by the urging force of the spring 41 (the moved position is referred to as a brake depression corresponding position 40a), and the brake pedal 13 is depressed. Is stopped, the brake pedal 13 is pushed into the casing 50 against the urging force of the spring 41 (the pushed position is referred to as a brake-free corresponding position 40b).
[0018]
The brake interlock member 40 has a sixth contact surface 42. When the brake interlock member 40 is located at the brake-free corresponding position 40b, the sixth contact surface 42 enters the movement locus of the third contact surface 25 of the shift interlock member 20. The in-plane direction of the sixth contact surface 42 is a direction that can contact the third contact surface 25 when the shift interlock member 20 rotates. The sixth contact surface 42 only needs to be able to contact the third contact surface 25, and the in-plane direction does not have to be orthogonal to the in-plane direction of the third contact surface 25.
[0019]
Next, the positional relationship (configuration) of the shift interlock member 20, the key interlock member 30, and the brake interlock member 40 in each state will be described together with the operation (operation) thereof.
[0020]
(1) The shift interlock member 20 is located at the shift lock position 20a, the key interlock member 30 is located at the key lock release position 30a, and the brake interlock member 40 is located at the brake free corresponding position 40b.
At this time, the first contact surface 22 of the shift interlock member 20 is located at a position deviated from the movement trajectory of the fourth contact surface 33 of the key interlock member 30, and hinders the movement of the key interlock member 30. There is nothing. Therefore, the key interlock member 30 is rotatable between the key unlock position 30a and the key lock position 30b. That is, an ignition key (not shown) can be operated freely.
[0021]
The third contact surface 25 of the shift interlock member 20 is outside the movement trajectory of the brake interlock member 40, and the brake interlock member 40 is movable between a brake-free corresponding position 40b and a brake depression corresponding position 40a. It is. That is, the depression and release of the brake pedal 13 can be freely performed.
[0022]
Since the key interlock member 30 is located at the key unlock position 30a, the fifth contact surface 34 of the key interlock member 30 is shifted to the second contact surface 23 of the shift interlock member 20. In the locus of movement. Therefore, even if the shift interlock member 20 is moved from the shift lock position 20a to the shift lock release position 20b, the second contact surface 23 contacts the fifth contact surface 34, and the shift interlock member 20 is moved. It cannot be moved to the shift lock release position 20b. Also, in the shift interlock member 20, since the brake interlock member 40 is located at the brake-free corresponding position 40b, the sixth contact surface 42 of the brake interlock member 40 has the third contact surface of the shift interlock member 20. It is in the movement locus of the surface 25. Therefore, even if the shift interlock member 20 is to be moved from the shift lock position 20a to the shift lock release position 20b, the third contact surface 25 contacts the sixth contact surface 42. Cannot be moved to the shift lock release position 20b.
[0023]
(2) The ignition-on / brake-free key interlock member 30 moves to the key lock position 30b. The brake interlock member 40 is located at the brake-free corresponding position 40b.
In the shift interlock member 20, the fifth contact surface 34 of the key interlock member 30 deviates from the movement path of the second contact surface 23 of the shift interlock member 20, but the sixth contact surface of the brake interlock member 40. Since the contact surface 42 enters the movement trajectory of the third contact surface 25 of the shift interlock member 20, when the shift interlock member 20 is moved from the shift lock position 20a to the shift lock release position 20b, the key interlock member 30 is moved. Does not hinder the movement of the shift interlock member 20, but the third contact surface 25 contacts the sixth contact surface 42. Therefore, the shift interlock member 20 cannot be moved to the shift lock release position 20b.
[0024]
{Circle around (3)} Ignition-on-brake depression key interlock member 30 is located at key lock position 30b. The brake interlock member 40 moves to the brake depression corresponding position 40a.
In the shift interlock member 20, the fifth contact surface 34 of the key interlock member 30 is out of the movement locus of the second contact surface 23 of the shift interlock member 20, and the sixth interlock member 40 has the sixth contact surface 34. Since the contact surface 42 of the shift interlock member 20 deviates from the movement locus of the third contact surface 25 of the shift interlock member 20, when the shift lock position 20a is moved to the shift lock release position 20b, the key interlock member 30 and the brake The interlock member 40 does not hinder the movement of the shift interlock member 20. Therefore, the shift interlock member 20 can be moved from the shift lock position 20a to the shift lock release position 20b. As a result, the shift lever (not shown) can be operated to a position other than the P position.
In addition, the order of the brake depression and the ignition on may be either order.
[0025]
(4) When the shift interlock member 20 is located at the shift lock release position 20b (when the shift lever is at a position other than the P position).
The first contact surface 22 of the shift interlock member 20 enters the movement trajectory of the fourth contact surface 33 of the key interlock member 30. Therefore, even if the user attempts to operate the ignition key (or attempt to remove the key), the key interlock member 30 comes into contact with the first contact surface 22 because the fourth contact surface 33 contacts the first contact surface 22. It cannot be moved from the position 30b to the key unlocking position 30a. Therefore, the ignition key cannot be removed.
Since the shift interlock boss portion 24 is outside the movement locus of the brake interlock member 40, the brake interlock member 40 can freely operate the brake.
[0026]
Next, the operation of the embodiment of the present invention will be described.
In the embodiment of the present invention, the following operations (1) to (5) can be obtained.
{Circle around (1)} Since the first to third contact surfaces 22, 23, 25 are located farther from the shift interlock rotation shaft 21a than the sliding surface of the rotation of the shift interlock member 20, the rotation center is increased. However, even if there is sliding resistance, the approach, contact and separation movements of the first to third contact surfaces 22, 23, 25 are hardly affected. Therefore, the sliding resistance of the rotary bearing 21 does not matter, and the stopper mechanism works smoothly.
{Circle around (2)} Since the key interlock member 30 and the brake interlock member 40 abut on the shift interlock member 20, the shift interlock member 20 is provided with a concave portion, and does not enter the concave portion and cross each other. Therefore, it is only necessary to have an accuracy of contacting the contact surface, and high accuracy is not required.
{Circle around (3)} Since the rotation bearing has a generally used structure, it can be easily manufactured and processed with high accuracy.
{Circle around (4)} The connection portion between the key interlock cable 12 and the key interlock member 30 is set near the key interlock rotation shaft 31a of the key interlock member 30, and the positions of the fourth and fifth contact surfaces 33 and 34 are set. By setting the distal end portion away from the key interlock rotation shaft 31a, the operation amount of the key interlock member 30 can be increased even when the ignition key operation stroke is small. Therefore, the operation amount of the key interlock member 30 can be easily adjusted.
{Circle over (5)} The brake interlock member 40 is a single component, and the spring 41 is also a single component, so the number of components is small.
[0027]
【The invention's effect】
According to the shift lock device of the first or second aspect, the following effects can be obtained.
Since the contact surface is located farther from the center of rotation than the sliding surface of rotation, even if there is sliding resistance at the center of rotation, the approach, contact, and separation movements will be affected by it. Less is. For this reason, the sliding resistance of the rotating bearing does not matter, and the stopper mechanism works smoothly.
Further, since the key interlock member and the brake interlock member abut on the shift interlock member, a concave portion is provided in the shift interlock member, and the shift interlock member does not enter the concave portion and intersect. Therefore, it is only necessary to have an accuracy of contacting the contact surface, and high accuracy is not required.
Further, since the rotating bearing has a generally used structure, it can be easily manufactured and processed with high accuracy.
