Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a select lever device for automatic transmission, especially a select lever mounted on a support frame. It supports the vehicle body so that it can be moved in the front-rear direction and left-right direction, and also plans for its movement. This type has a stepped guide hole through which the select lever can be inserted. The present invention relates to a guide hole closing structure in a select lever device.

0002

[Conventional technology]

Conventionally, in this type of select lever device, the opening of the guide hole is closed. For example, insert the select lever so that it can swing from side to side. The first slide plate, which has a long hole to cover the guide hole, can be slid in the front and rear directions on the support frame. furthermore, the first slide plate is attached to the select lever and has the elongated hole. A structure is known in which a closing second slide plate is supported so as to be slidable in the left and right direction. However, with such a structure, it follows the left and right rocking of the select lever and moves in the same direction. The select lever moves the sliding second slide plate itself to any swing position in the left or right direction. Even if there is a long hole, it should be formed sufficiently large in the left and right direction so that it can reliably close the long hole. For this reason, the second slide plate is at its left and right movement limits, and the first slide plate is It protrudes outward from the side edge of the plate, which not only increases the size of the device, but also causes the guide groove to become too large. Other functional parts such as an indicator lamp for displaying the select position along one side of the There is a risk of interference.

0003 Therefore, in order to solve this problem, for example, Japanese Patent Application Laid-Open No. 63-205715 As disclosed in By connecting the rotating cover to the sliding plate, the space occupied by the cover is minimized. A device that can be made smaller has already been proposed.

0004

[Problem that the idea aims to solve]

However, in the above proposal, there is a top that rotates around a pivot provided protruding from the slide plate. Insert the select lever into the rotating cover so that it can slide in a direction perpendicular to it. A notch groove is formed, and the engagement between the notch groove and the select lever causes the lever to Since the rotating cover is designed to rotate in conjunction with each other, its notch groove overlaps with the elongated hole. In this case, the overlapping part cannot be completely covered by the rotating cover. There was a problem.

[0005] The present invention was proposed in view of the above, and the long hole of the slide plate is connected to the rotating cover. A selection for automatic transmissions that does not cause the above problem even though it is blocked by An object of the present invention is to provide a guide hole closing structure in a lever device.

[0006]

[Means to solve the problem]

In order to achieve the above purpose, this invention has a select lever mounted on the support frame in the longitudinal direction of the vehicle body. and support movably in the left and right directions, and to guide the movement. A step-shaped guide hole through which the select lever is inserted is provided, and the select lever The guide hole is closed by having a long hole through which the guide hole is inserted to allow movement of the guide hole in the left and right direction. The automatic transmission set includes a sliding plate slidably mounted on the support frame in the longitudinal direction. In the select lever device, the slide plate is configured to rotate the select lever relative to each other. It has an insertion hole through which it can be inserted movably and immovably in a direction perpendicular to the lever. The rotating cover is overlapped so that the rotating cover always covers the overlapping part of the elongated hole and the guide hole. Place the cover on the left and right sides of the select lever between the cover and the slide plate so as to close the cover. It is equipped with an interlocking rotation mechanism that rotates around the lever in conjunction with the movement in the direction. Features.

【Example】

Below, one embodiment of the present invention will be explained with reference to the drawings. The automatic transmission, which has an operation knob 1c on the upper end, can be seen from the floor console Cf where it is placed. The select lever L is upright, and the base 1a of the select lever L is It is supported by a support frame 2 housed within the console Cf.

As shown in FIG. 2, the support frame 2 is composed of a box-shaped frame body 2m fixed to the vehicle body, and a cover plate 2t detachably attached to the open upper end of the frame body 2m. A first support shaft ₃₁ extending in the left-right direction of the vehicle body is rotatably connected horizontally to the left and right side walls of the frame body 2m, and a select lever L is connected to the first support shaft ₃₁ . A second support shaft ₃₂ that is fitted into the base portion 1a and extends in the longitudinal direction of the vehicle body passes through the select lever L, so that the select lever L can be swung in either the longitudinal direction or the left or right direction of the vehicle body. Although not shown, a return spring is interposed between the select lever L and the frame body 2m to always swing and bias the lever L to the left.

[0009]The base portion 1a of the select lever L is connected to the end of an operating wire 4 that is connected to a manual valve and a parking brake lever of an automatic transmission (not shown), so that the lever L is connected to the first support shaft 3. By swinging the automatic transmission forward and backward in _one rotation, the automatic transmission can be shifted sequentially from the front to parking position "P", reverse position "R", neutral position "N", and up to 4th gear. It is possible to switch to position "D ₄ ", drive position "D ₃ " which allows automatic shifting up to third speed, second position "2", and low position "1".

0010 The cover plate 2t of the support frame 2 is exposed through the opening of the floor console Cf. The shaft portion 1b of the select lever L is inserted through the cover plate 2t, and the lever L is A guide hole 5 that guides the swing, and a select lever on one left and right side of the guide hole 5. A display window plate 6 made of a transparent material is provided to display the selection position of L, and the display window plate 6 An indicator lamp device 7 that illuminates the window plate 6 from below is provided directly below. Incidentally, the indicator lamp device 7 has a single lamp that covers the display window plate as shown in the example shown in the figure. The entire display panel 6 may be irradiated, or a plurality of display windows corresponding to each selection position of the display window panel 6 may be irradiated. The display portion may be individually irradiated with a plurality of lamps.

The guide hole 5 has a plurality of vertically extending portions extending in the same direction to guide the swinging of the select lever L in the front-rear direction, and a plurality of longitudinal portions extending in the same direction to guide the swinging of the select lever L in the left-right direction. The horizontally elongated portion _of When changing from the ``'' position to the ``2'' or ``1'' position, the select lever L must first be swung to the right against the biasing force of the return spring. It is designed so that it cannot be shaken.

0012 A slide plate 8 that closes the guide hole 5 from below is superimposed on the back surface of the cover plate 2t. The slide plate 8 is composed of a band-shaped elastic plate that is curved upward in a free state. , both longitudinal ends thereof are provided with guide holes 11 bored in the front and rear end walls of the cover plate 2t, respectively. It slidably passes through and extends outward. In the middle part of the slide plate 8, , insert the shaft portion 1b of the select lever L so as to allow it to swing in the left and right direction. A long hole 8a is bored.

[0013] In addition, the shaft portion 1b of the select lever L is connected to a rotating cover that overlaps the lower surface of the slide plate 8. -9 into the insertion hole 9b, but not movable in the direction perpendicular to the lever L. The notched groove 9a provided on the outer periphery of the rotating cover 9 has a slider inserted therethrough. An engaging pin 10 integrally protruding from the lower surface of the plate 8 is slidably engaged with the pin 1. A retaining flange 10f that prevents the cover 9 from falling is integrally connected to the tip of the cover 0. It is. Therefore, when the select lever L swings in the left-right direction, the cover 9 engages with the engagement pin. 10 and the notch groove 9a, the lever L rotates around the shaft portion 1b. At any rotational position, the opening of the elongated hole 8a (i.e., the overlapping part with the guide hole 5) The amount of overhang of the cover 9 from the side edge of the slide plate 8 is zero or so that it can be closed. The shape of the cover 9 is determined so that the size of the cover 9 is small. Therefore, the notch groove 9a and The engagement pins 10 cooperate with each other to move the rotating cover 9 in the left and right direction of the select lever L. This constitutes an interlocking rotation mechanism I of the present invention that rotates in conjunction with movement.

Next, the operation of the above embodiment will be explained. Since the shape of the guide hole 5 is stepped as described above, when shifting the select lever L from the "P" position to the "R" position, for example, the lever L is moved as shown by the arrow in FIG. It is difficult to swing it backwards unless you first swing it to the right. When the select lever L swings in the left-right direction, the rotating cover 9 moves around the shaft portion 1b of the select lever L to the dotted line position in FIG. Since the opening of the elongated hole 8a can be closed from beginning to end by rotating from A to the chain line position B (right-hand swing limit position), it not only looks good but also prevents dust, etc. from passing through the elongated hole 8a. Intrusion is also prevented. The closing action of the cover 9 on the elongated hole 8a can be achieved, for example, by rotating the cover 9 to the chain line position C (left swing limit position) in FIG. 5 in order to shift the select lever L to the "D ₃ " position. The same result can be achieved if

[0015] However, unlike the above embodiment, the cover for closing the long hole 8a is, for example, a slider. Assuming that the structure is held on the board 8 so that it can slide in the left and right direction, in that case, The elongated hole 8a is always closed regardless of the horizontal swing position of the select lever L. It is necessary to form the cover long in the left and right direction so that the At the sliding limit, as shown by chain lines Dl and Dr in FIG. However, in the previous embodiment of this invention, the select lever - Since the horizontal swinging of L is converted into the rotational movement of the cover 9, the movement of the cover 9 is The occupied space can be made as small as possible in the horizontal direction, and the above-mentioned problem is solved.

[0016]

[Effect of the idea]

As described above, according to the present invention, the select lever can be moved in the left and right direction. The slide plate, which has a long hole through which it is inserted so as to close the step-shaped guide hole, has a selector plate. Insert the lever so that it can rotate relatively and cannot move relatively in the direction orthogonal to the lever. A rotating cover having an insertion hole is overlapped, and the rotating cover is inserted into the elongated hole and the insertion hole. The cover is placed between the cover and the slide plate so as to always close the overlapping part of the inner hole. Interlocking rotating machine that rotates around the lever in conjunction with the horizontal movement of the lever Since the structure is interposed, the above-mentioned rotating cover rotates in conjunction with the left and right movement of the select lever. can always reliably close the elongated hole no matter which rotational position it is in. Not only does it look good, but it also prevents dust, etc. from entering the support frame through the long holes. can be effectively prevented.
