BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift lever device for shifting a transmission of an automobile.

[0002]

2. Description of the Related Art Conventionally, as a shift lever device of this type, for example, as described in Japanese Utility Model Laid-Open No. 62-158519, a shift knob is provided with a knob button, and the shift restricting body is restricted by pushing the knob button. There is a type to release. Alternatively, as described in the Honda Service Manual, Inspire / SABER95-2, pages IV-8 to IV-9, there is a type that releases the restriction of the shift restriction body by pushing down the shift knob and lever from above. is there.

[0003]

However, the type in which the knob knob is provided in the shift knob requires a certain size in order to ensure the ease of pushing the knob button, and as a result the shift knob itself is There is a problem of increasing the size. There is also a problem that when the driver grips the shift knob, the knob button is touched by the hand and the grip feeling is poor.

Further, in the type in which the shift knob and the lever are pushed down from above, when a force is applied to the shift knob from above while the lever is shift-locked by the shift lock mechanism, an excessive load is shifted via the lever. There is a problem that it may be transmitted to the lock mechanism and damage the shift lock mechanism and the like. The present invention has been made in view of such problems, and an object thereof is to provide a shift lever device that does not require a knob button.

Another object of the present invention is to provide a shift lever device which does not damage the shift lock mechanism and the like even when an excessive force is applied to the shift knob from above.

[0006]

In order to achieve the above object, a shift lever device according to a first aspect of the present invention has a base portion swingably attached to a vehicle body and an upper portion from the base portion. A lever having an extending tubular portion, a compression rod inserted through the tubular portion of the lever, an elastic body interposed between the compression rod and the base portion of the lever to urge the compression rod upward, and a compression rod. A position pin that is integrally attached to the compression rod at an intermediate position in the vertical direction of the rod and projects laterally from a side hole formed in the side wall of the tubular portion of the lever, and determines the upper limit position of the position pin and the position pin. Shift restricting body that allows the swinging motion of the lever when it moves down, and the cylindrical shape of the compression rod and lever And a shift knob that accommodates the respective upper end portions of the shift knob, and the shift knob is slidably attached to the tubular portion of the lever in the vertical direction, and the shift knob and the compression rod are mounted between the shift knob and the compression rod. It is characterized in that a transmission means for transmitting one up-and-down movement to the other is provided, and the position pin is moved down by the shift knob being moved down.

According to a second aspect of the present invention, in the first aspect, the transmission means is a second elastic body that biases the shift knob upward with respect to the compression rod. According to claim 3, the claim 2
In the described one, inside the shift knob, a first space portion that accommodates an upper end portion of the compression rod so as to be vertically movable, and a first space portion that accommodates an upper end portion of a tubular portion of the lever that is vertically movable. 2 spaces are formed, and the distance from the upper end of the compression rod to the upper surface of the first space is the tubular part of the lever when the position pin is at the upper limit position by the shift restricting body. Is longer than the distance from the upper end to the upper surface of the second space.

According to the fourth aspect, the second or third aspect is
The urging force by which the elastic body urges the compression rod upward in the state described above is lower than the urging force by which the second elastic body urges the shift knob upward. It is characterized by being small. According to a fifth aspect of the present invention, in the third aspect, the first space portion of the shift knob is provided with a rotation restricting portion that restricts a rotation range of the upper end portion of the compression rod in the first space portion. It is characterized by

According to a sixth aspect, in the fifth aspect, an upper end portion of the compression rod has a non-circular shape, and is between the first space portion and the second space portion. Has a communication hole through which the upper end of the compression rod can be inserted only at a predetermined rotation angle, and the upper end of the compression rod is approximately 90 degrees from the predetermined rotation angle in the first space. It is characterized in that the rotation restricting portion is provided which abuts the upper end portion in a rotated state and prohibits rotation of the upper end portion.

[0010]

According to the first aspect of the invention, by pushing the shift knob from above to move it downward with respect to the tubular portion of the lever, the position pin moves downward and the shift restricting body swings the lever. Since the movement is possible, the shift knob does not need a knob button or the like, and the shift knob itself can be miniaturized.

Further, in the shift lever device having the conventional knob button, only the shift knob and the compression rod need be changed, so that the design can be easily changed. According to the invention of claim 2, in addition to the effect of the invention of claim 1, since the force from the shift knob is transmitted to the compression rod via the second elastic body, the position pin is locked. Even if the shift knob is forcibly pushed down at a certain time, the second elastic body contracts to absorb the downward movement of the shift knob, so that the compression rod, the position pin, the shift lock mechanism and the like can be prevented from being damaged.

According to the third aspect of the invention, in addition to the effects of the first and second aspects of the invention, when the position pin is in a locked state, the shift knob is further pushed down by excessive force. However, since the shift knob directly contacts the upper end of the cylindrical portion of the lever before the shift knob directly contacts the upper end of the compression rod, excessive force from the shift knob is directly transmitted to the lever and the Because it is transmitted through the elastic body of 2,
The load on the compression rod, the position pin, the shift lock mechanism, etc. can be reduced, and damage to these can be prevented.

According to the invention of claim 4, in addition to the effects of the invention of claims 1 to 3, the urging force by which the elastic body urges the compression rod upward when the shift knob is moved downward is , The second elastic body is smaller than the urging force that urges the shift knob upward, in other words, the shift knob and the compression rod are relatively rigidly connected, so that the position pin is locked. When the vehicle is in the closed state, the driver can be made aware that the vehicle is locked. Also, even during normal shift operation, the force applied to the shift knob is transmitted to the compression rod via the second elastic body, and the position pin is efficiently moved downward against the biasing force of the first elastic body. Can be made.

According to the invention of claim 5, in addition to the effects of the inventions of claims 1 to 3, the rotation restricting portion allows
Since the relative rotation between the shift knob and the compression rod is limited, the shift knob can always be placed in the correct rotational angular position with respect to the compression rod. According to the invention described in claim 6, in addition to the effects of the invention described in claims 1 to 3 and 5, the compression rod can be inserted into the space from the second space portion through the communication hole. Since the rotation is restricted by the rotation restricting part while the compression rod is rotated 90 degrees in the space, the work of assembling the compression rod and the shift knob can be easily performed, and the shift knob is always in the correct angular position with respect to the compression rod. Can be placed at

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a shift lever device according to the present embodiment (a sectional view taken along line 1-1 of FIG. 2).
2 is a front view. In the figure, a shift lever device 10 includes a base portion 14a swingably attached to a base bracket 12 fixed to a vehicle body 1 and a tubular portion 1 welded to the base portion 14a and extending upward from the base portion 14a.
4b and a cylindrical portion 14b of the lever 14
A compression rod 16 that is inserted through the inside, a first spring (elastic body) 18 that is interposed between the compression rod 16 and the lever base portion 14a and biases the compression rod 16 upward, and a vertical direction of the compression rod 16. The cylindrical portion 14a of the lever 14 is integrally attached to the compression rod 16 at an intermediate position in the direction.
Position pin 20 protruding laterally from a side hole 14c formed in the side wall of the base plate, a shift restricting body 22 extending above the base bracket 12, and the compression rod 1
6 and the shift knob 24 that accommodates the respective upper end portions of the tubular portion 14b of the lever 14.

As shown in FIG. 2, the shift restrictor 22 is provided with a slot 22a corresponding to the shift range. For example, the first cutout 22b of the rightmost slot 22a in the figure is P. Range, the second notch 22c is the R range,
The third cutout 22d corresponds to the N, D, 1, and 2 range positions, and the slot 22a determines the upper limit position of the position pin 20 and when the position pin 20 moves downward, the range (P (Between the range and the R range), allowing the rocking movement of the lever 14.

Further, a shift lock mechanism 26 is arranged outside the shift restricting body 22. Shift lock mechanism 2
6 is composed of a shift lock solenoid 28 and a lock lever 30 rotatably attached to the base bracket 12, and the rod 28a of the shift lock solenoid 28 extends when the brake pedal is not stepped on even if a key input is made. In this state, the lock lever 30 is held in the closed state and the rotation of the lock lever 30 is prevented, and the position pin 20 is prevented from moving downward from the first cutout portion 22b.

The shift knob 24 is a cylindrical portion 1 of the lever 14.
4b is attached so as to be slidable in the vertical direction. A sliding member 32 made of plastic is fixed to the upper end of the tubular portion 14b of the lever 14 to avoid direct sliding between the shift knob 24 made of plastic and the lever 14 made of metal, and Sliding between the shift knobs 24 is made smooth.

Inside the shift knob 24, a first space portion 24a for accommodating the upper end portion 16b of the compression rod 16 so as to be vertically movable, and a tubular portion 14b of the lever 14.
Second space portion 24 for accommodating the upper end portion of the movable body in the vertical direction
b and a communication hole 24c that communicates between the first space portion 24a and the second space portion 24b are formed. The upper surface of the second space portion 24b of the shift knob 24 and the compression rod 16
Between the receiving plate 16a of the compression rod 16
Urging the shift knob 24 upward against the shift knob 2
A second spring (elastic body) 34 that serves as a transmission means for transmitting the vertical movement of one of the compression rod 16 and the compression rod 16 to the other is provided. The shift knob 24 is sandwiched and held by the upper end portion 16b housed in the first space portion 24a and the second spring 34.

The upper end 16 of the compression rod 16
The distance L1 from b to the upper surface of the first space portion 24a of the shift knob 24 is the upper end of the tubular portion 14b of the lever 14 when the position pin 20 is at the upper limit position by the shift restricting body 22 (the state shown in FIG. 1). Longer than the distance L2 from the upper part to the upper surface of the second space 24b (L1> L2)
Is set to.

The spring force of each of the first spring 18 and the second spring 34 depends on the position pin 2
In the state in which 0 is moved downward, the spring force (biasing force that urges upward) given by the first spring 18 to the compression rod 16 and the spring force given by the second spring 34 to the shift knob 24 ( It is set to be smaller than the urging force that urges upward).

The shift lever device 1 thus constructed
At 0, the work of assembling the shift knob 24 to the compression rod 16 is performed as shown in FIGS. 4 and 5 (FR indicates the front direction of the vehicle body). That is, the upper end portion 16b of the compression rod 16 has, for example, a substantially elliptical non-circular shape that extends in only one direction, and the communication hole 24c matches the shape of the upper end portion 16b, and its width w is the upper end. The portion 16b is slightly larger than the short axis and smaller than the long axis, and the depth d is larger than the upper end portion 16b.
Is set longer than the major axis of the ellipse. Therefore, the upper end portion 16b can be inserted through the communication hole 24c only at an angle whose long axis substantially coincides with the depth direction of the communication hole 24c, and after the upper end portion 16b reaches the first space portion 24a,
The upper end 16b is rotated 90 degrees clockwise in FIG. In the first space portion 24a of the shift knob 24, a pair of rotation restricting portions 24d are symmetrically projecting in the first space portion 24a, and when the upper end portion 16b tries to rotate more than 90 degrees, the upper end portion 16b is rotated. And the rotation of the upper end portion 16b is prohibited. Therefore, the operator may press the compression rod 1 until the upper end 16b hits the rotation restricting portion 24d.
By rotating 6 the compression rod 16 and the shift knob 24 can be positioned in the rotational direction.

Next, the operation of the shift lever device 10 will be described. For example, the position pin 20 has the first notch 2
When shifting from the state of 2b, when the shift knob 24 is grasped and pushed downward, the second spring 3
The force is transmitted to the compression rod 16 via 4, and the position pin 20 moves downward against the spring force of the first spring 18. When the shift lock solenoid 28 is not excited, its rod 28a
Can be retracted, and the position pin 20 removes the first cutout portion 22b while rotating the lock lever 30, so that the lever 14 can be swung and a shift to another range is possible.

On the other hand, when the shift lock mechanism 26 is actuated and the shift lock solenoid 28 is excited, the rod 28a thereof is held in a protruding state, so that the lock lever 30 cannot rotate and the position pin 20 does not rotate. The lock lever 30 prevents its downward movement. In this state, even if the shift knob 24 is forcibly pushed down without noticing that the driver is locked, the second spring 34 contracts to absorb the downward movement of the shift knob 24. The lock lever 3 of the pin 20 or the shift lock mechanism 26
It is possible to prevent 0 from being damaged.

Further, the driver uses excessive force to shift the knob 2
4 is pushed down, L1> L2, and therefore, as shown in FIG. 3, before the upper surface of the first space portion 24a of the shift knob 24 contacts the upper end portion 16b of the compression rod 16, the second portion of the shift knob 24 The upper surface of the space portion 24b contacts the upper end portion of the tubular portion 14b of the lever 14. Therefore,
Excessive force from the shift knob 24 is a lever 1 that is strong in strength.
4 to the compression rod 16 via the second spring 34, the load on the compression rod 16, the position pin 20, or the lock lever 30 of the shift lock mechanism 26 can be reduced, and damage to them can be prevented. .

Further, when the shift knob 24 is moved downward, the spring force exerted by the first spring 18 on the compression rod 16 (biasing force for urging upward).
Is set to be smaller than the spring force (biasing force that urges upward) of the second spring 34 to the shift knob 24. In other words, the shift knob 2
4 and the compression rod 16 are connected more rigidly than between the compression rod 16 and the base portion 14a, and therefore, the shift knob 24 receives the fact that the position pin 20 is locked. The driver can perceive with the force. Further, even during a normal shift operation, the force applied to the shift knob 24 is transmitted to the compression rod 16 via the second spring 34, and the position pin 20 is efficiently moved against the spring force of the first spring 18. Can be moved down well.

Next, FIG. 6 shows only a portion of the shift lever device according to another embodiment of the present invention which is different from FIG. In the figure, the compression rod 1
6, a diametrically expanded portion 16c is formed instead of the receiving plate 16a, and a neck portion 16d is formed in the central portion in the vertical direction of the diametrically expanded portion 16c.

It is biased inward.

Even with such a structure, the shift knob 24 and the compression rod 16 are transmitted by the transmission means.
The vertical movement of one is transmitted to the other, and even if the shift knob 24 is pushed down while the position pin 20 is locked, the downward movement of the shift knob 24 is absorbed. Further, the ball 38 is biased in the direction to return to the inside of the neck 16d, so that the driver can be informed that the position pin 20 is locked.

Next, FIG. 7 shows a portion of a shift lever device according to still another embodiment of the present invention, which is different from that shown in FIG. In this example, a leaf spring 40 is used instead of the spring 36 and the ball 38 of FIG. 6 as the transmission means, and the bent portion 40a of the leaf spring 40 is fitted into the neck portion 16d so that the bent portion 40a is directed inward in the neck portion 16d. Is urged.

Even with such a structure, the shift knob 24 and the compression rod 16 are transmitted by the transmission means.
The vertical movement of one is transmitted to the other, and even if the shift knob 24 is pushed down while the position pin 20 is locked, the downward movement of the shift knob 24 is absorbed. Further, the leaf spring 40 is biased in the direction of returning to the inside of the neck 16d, so that the driver can be informed that the position pin 20 is locked.

Further, the bent portion 40a of the leaf spring 40 has the neck portion 1
Since the shift knob 24 and the compression rod 16 are positioned in the vertical direction by being fitted into the 6d, the vertical rattle of the shift knob 24 can be prevented. In each of the embodiments described above, only the shift knob 24 and the compression rod 16 need be changed mainly in the shift lever device having the conventional knob button, so that the design change from the conventional product is easily performed. be able to.
