Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a change lever operation device, and more particularly, the present invention relates to a change lever operation device, and more particularly, it is possible to adjust the position of a grip portion for gripping a knob constituting a change lever, and thereby to adjust the position of a grip portion for gripping a knob constituting a change lever. The present invention relates to a change lever operating device configured to be easily mounted on an actual vehicle in different positions to automatically perform gear switching operations of a transmission.

For example, in the research and development process for passenger cars, it is common to drive the actual vehicle indoors with test equipment in advance for the purpose of testing the performance of a prototype vehicle or testing for a specific research topic. . This is usually called a real vehicle driving test.

In this actual vehicle driving test, the actual vehicle is often driven continuously for a long period of time to obtain test data, so an automatic driving system is adopted as the driving method. This automatic driving device is equipped with, for example, a transmission shift operation, a clutch pedal, and an accelerator pedal operation mechanism.

Therefore, FIG. 1 shows an example of a conventional technology operating device.

In other words, this mission control device is the 60th-5th
The technical idea disclosed in No. 39, the support stand 2
A select arm 4 is arranged above, and this select arm 4
is swingable in the X-axis direction by a select cable 6. On the other hand, a spline shaft 12 is connected to the shift cable 8 via a bearing box 10, and a shift arm 14 is fixed to one end of the spline shaft 12. A chuck member 16 is disposed at the tip of the shift arm 14, and the chuck member 16 can grip the shaft of the change lever 18. - Therefore, in the above configuration, the chuck member 16 can be displaced in the X direction and the Y direction by appropriately pulling the select cable 6 and the shift cable 8, and therefore, the chuck member 16 can be gripped by the chuck member 16. Tests are performed by switching the change lever 18 to low, second, third, back, etc.

However, in the transmission operation device as described above, the chuck member 16 is configured to grip the shaft portion of the change lever 18 during a gear change operation. Therefore, when performing automatic operation, it is usually necessary to remove the knob fixed to the tip of the change lever 18 in order to engage the chuck member 16 with the shaft of the change lever 18. That is, during the test, the complexity of the operation of attaching the change lever 18 was revealed.

Furthermore, in modern transmissions, the shaft portion of the change lever is often covered with a change lever boot made of synthetic resin or the like in order to prevent the intrusion of dust and the like and to improve aesthetics. Therefore, in practice, it is difficult to engage the chuck member 16 with the shaft portion.

The present invention has been made in order to overcome the above-mentioned disadvantages, and is configured such that at least a grip portion for gripping a knob attached to the tip of a change lever is adjustable in position, and the change lever is shifted. Adjustable movement transmission means is interposed between the drive source for displacing the direction and the selection direction, and these adjustment mechanisms allow the gripping portion to be adjusted to knobs of different car models and, therefore, of different arrangement positions. It is an object of the present invention to provide a change lever operating device that can be installed easily and in a short time.

In order to achieve the above object, the present invention includes a connecting member which is movable and rotatable in the axial direction of an actuator that is linearly displaced, and a first arm member which is movable in the direction perpendicular to the axial direction. A second arm member is attached to the first arm member so as to be freely displaceable in the same direction as the axial direction, and a grasping means for grasping a gear change knob of an automobile is provided at a predetermined portion of the second arm member. The gripping means is configured to be movable in a direction perpendicular to the direction of displacement of the second arm.

Next, preferred embodiments of the change lever operating device according to the present invention will be described in detail with reference to the accompanying drawings.

In FIGS. 2a and 2b, the change lever operating device is substantially composed of a main body portion 40, a drive mechanism portion 42, and a gripping mechanism portion 44 for gripping the knob of the change lever. In this case, the main body 40 includes a housing 46,
Although not shown inside this housing 46, there is a drive mechanism section 4.
a first actuator that displaces 2 in the direction of arrow B;
A second actuator for rotating in the direction of arrow C is installed inside. In fact, the first actuator is connected to the select shaft 4, and the second actuator is connected to the shift shaft 50.

First, the drive mechanism section 42 will be explained.

The select shaft 48 is fixed to one end of a bearing 49, while the shift shaft 50 is slidably splined to a connecting member 52, which is rotatably supported by the bearing 49. A shaft 56 extends from the other end of the connecting member 52 , and a guide rail 58 is attached to the tip of the shaft 56 .
0.

Therefore, the linear motion of the select shaft 48, that is, the displacement motion in the direction of arrow B, is transmitted to the connecting member 52 via the bearing 49, and the connecting member 52 slides with respect to the shift shaft 50, and the guide rail 58 Displace. On the other hand, the rotational movement of the shift shaft 50 is transferred from the connecting member 52 to the guide rail 58 by spline connection.
It is easy to understand that this is conveyed to

Next, narrow protrusions 62a and 62b are formed along the longitudinal direction on both sides of the guide rail 5 (second
(See Figures 4 to 4). In this case, the protrusions 62a, 62
Guide rollers 64a and 64b and 66a and 66b are shown in FIG.
b engages. That is, the two sets of guide rollers 64a, 64b and 66a, 66b facing each other are spaced apart from each other by a predetermined distance, and the bearings 70a, 70b and the bearing 72a
,? It is rotatably supported via 2b. In fact, circumferential grooves 74a, 74b and circumferential grooves 76a, 76b are carved in the guide rollers 64a, 64b and 66a, 66b, respectively, and the line shapes formed in the guide rail 58 are formed in these circumferential grooves 74a, 74b. protrusions 62a, 62b
is engaged. The rods that pivotally support the guide rollers 64a, 64b and 66a, 66b have elongated holes 8 in the center.
It is locked to a support plate 82 defining 0.

Therefore, the shaft 56 passes through this long hole 80 and supports the guide rail 58.

Therefore, the first arm member 88 is attached to the support plate 82. That is, as shown in FIG.
One end of the arm member 88 is fixed to the support plate 82, the other end is slightly bent from the vertical direction, and the end is horizontal. At the end of the first arm member 88, as shown in FIGS.
It is movably fixed via poles 106 and 108 inserted in 04.

The end portion of the second arm member 102 is formed into a U-shape, thereby defining a large groove portion 110.

The third arm member 114 is formed to have a T-shaped cross section, and a horizontally extending portion 116 is connected to the groove portion 114.
Fits with 0. A long hole 118 is formed in the horizontal portion 116 extending in the longitudinal direction, and the third arm member 114 is opened by screwing the hole 20.122 into the hole formed in the third arm member 114. The arm member 114 is perpendicular to and movably connected to the second arm member 102 .

Therefore, the grip mount 124 is pivotally supported by the third arm member 114 via the engagement pin 126.

In this case, support plates 12B and 130 are fixed to both ends of the grip mount 124, respectively, and the first grip member 132 is attached to the ends of the support plates 128 and 130 via engagement pins 134 and 136. It is rotatably supported on the shaft.

Long poles 138 and 140 are screwed onto the first grip member 132, which is bent in a U-shape.
Rotation is prevented by 144. On the other hand, the other end of the bolt 138, 140 is screwed into the second grip member 146, and tightened with a wing nut (148, 150). In this case, a space is defined so that the first grip member 132 and the second grip member 146 can grip the substantially spherical change knob 20, and in order to further facilitate the gripping action, the first grip Member 132) Recesses 152 and 154 each having a curved surface are formed in each of the second grip members 146.

Note that a groove 158 is defined in the second grip member 146 so as to be perpendicular to the longitudinal direction thereof, and a groove 158 is defined in the second grip member 146 so as to be perpendicular to the longitudinal direction thereof.
The convex portion 162 of the stopper member 160 is fitted into the groove 158, and the wing nuts 14B and 150 are prevented from rotating by the side surface of the stopper member 160.

The change lever operating device according to the present invention is basically constructed as described above, and its functions and effects will be explained next.

First, as shown in FIG. 4, the change lever operating device main body 40 is placed in a predetermined position within the automobile, and is positioned by a fixing means (not shown).

After that, the second arm member 102 and the third arm member 1
14 with bolts 106.108 and 120.12 bolts respectively
Slide it with 2 loosened.

After positioning the gripping mechanism 44 with respect to the change knob 20 as described above, the change knob 20 is inserted into the space defined by the first grip member 132 and the second grip member 146.

At this time, the height of the change knob 20 is adjusted by vertically displacing the first arm member 88.

A support plate 82 with a lid and a first arm member 88 fixed thereto.
is the guide roller 64a, 64 with respect to the guide rail 58.
This is because it is freely displaceable via b, 66a, and 66b. In this manner, after the change knob 20 is held between the curved recesses 152 and 154 of the first grip member 132 and the second grip member 146, the change knob 20 is fixed by screwing the butterfly nuts 148 and 150. At this time, the grip mounting base 124 is rotatable by the engagement pin 126, and the first grip member 132 is rotated by the engagement pin 136.
．． It can be rotated by 136. Therefore, the gripping function can be easily performed regardless of the shape and position of the change knob 20. Note that a stopper member 160 is fitted to the second grip member 146 to prevent the wing nut 148, 150 from rotating, and then the bolt 106, 10
8. Fasten the bolts 120 and 122 to fix the second arm member 102 and the third arm member 114 to the first arm member 88.

In this way, the positioning adjustment of the change lever operating device main body 40 with respect to the change knob 20 is substantially performed by the second arm member 102) and the third arm member 11 fixed by the bolts 106.10B and 120.122.
This is done by adjusting the distance from the change knob 20 by sliding the knob 4 as appropriate.

Therefore, since there is no need to accurately position the change knob 20 and the gripping mechanism in advance with respect to the drive shaft, the main body portion 40 can be positioned extremely easily and in a short time.

Next, in the thus positioned state, an actuator (not shown) in the housing 46 is driven to cause the change lever operating device to perform a gear change operation. For example, in FIGS. 2a and 2b, the change lever 18 is assumed to be in the neutral position, and a case will be described in which the change lever 18 is displaced in the direction of the arrow to shift the gear from neutral to low.

First, a first actuator (not shown) inside the housing 46 is driven to displace the select shaft 48 in the direction of arrow B by a predetermined distance. As mentioned above, in the second case, the connecting member 52
is connected to the shift shaft 50 by a spline.

Therefore, the connecting member 52 is connected to the shift shaft 50.
At the same time, the rotational force from the shift shaft 50 is transmitted along with the bearing 49. At this time, since the knob 20 is gripped by the gripping mechanism 44, the displacement force on the shift shaft 50 and the select shaft 48 moves the support plate 82 connected to the first arm member 8 to the guide rollers 64a, 64b and 66
It will be displaced under the rotational action of a and 66b. Next, a second actuator (not shown) inside the housing 46 is driven to rotate the shift shaft 50 by a predetermined angle in the direction of arrow C in the figure. Therefore, the gripping mechanism 44 connected to the guide rail 78 by the movement of both
has the effect of displacing the change knob 20 to the low (L) position while gripping it. The displacement action of the two actuators (not shown) in the directions of arrows B and C causes the change knob 20 to move in an arc. However, in this case, the retaining pin 126 causes the grip mount 124 to rotate in the same direction as the arrow C direction, while the engaging pin 134.1
36, the first grip member 132) and the second grip member 146 are displaced in a direction perpendicular to the direction of arrow C. Therefore, this mechanism can accommodate displacement of the change knob 20 in any direction.

The above-described operations are similarly performed when shifting to other gears, such as second, third, or back gear, and at this time, the drive control of an actuator (not shown) may be performed as appropriate.

On the other hand, for vehicle models in which the height position of the change knob 20 is different, it goes without saying that the first arm member 88 and the like can be adjusted to W11.

Next, FIG. 6 shows another embodiment of the change lever operating device according to the present invention. Note that the same reference numerals are given to the same components as in the embodiment described above, and detailed explanation thereof will be omitted.

Therefore, in this embodiment, a plurality of screw holes 164 are formed in the connecting member 52 that is integral with the shift shaft 50, and a plurality of holes 166 are formed in the support plate 82. The support plate 82 is engaged with the connecting member 52 by screwing the bolt 165 into the screw hole 164 through the hole 166. Therefore, by appropriately selecting a plurality of screw holes 164, the degree of inclination of the support plate 82 with respect to the vertical direction can be arbitrarily selected, for example.

In practice, a nut 168 is screwed onto a screw 167 extending from the end of the shift shaft 50 to sandwich the connecting member 52 and the support plate 82.

On the other hand, on the 8th day of the first arm member, a set of elongated holes 170a and 170b are bored in the vertical direction in the figure, and a set of small holes 172a and 172b are formed in the guide rail 58.

The small holes 172a, 172b, the long hole 170a,
Insert bolts 174a and 174b into 170b and tighten nut 175a.

Tighten with 175b. Therefore, the position of the first arm member 88 can be adjusted in the vertical direction to some extent within the range of the elongated holes 170a and 170b. In addition, in the figure, reference numerals 176a and 17
6b are drilled in the support plate 82 and bolts 174a, 174
This is a recessed part for accommodating the head of part b.

Therefore, in view of this configuration, the guide rail 58 includes guide rollers 64a, 64b, and 66a.

Its side portion engages with 66b and is movable in the vertical direction in the figure. Furthermore, as described above, a plurality of holes are provided in the connecting member 52 to enable the angle of the support plate 82 to be adjusted. Therefore, even if the rotation range of the shift shaft 50 is limited, it is possible to adjust the angle of the support plate 82 and operate the change lever of a wide variety of automobiles. Note that the displacement operation of the first arm member 88 during actual change lever operation is similar to the embodiment described above, in which the guide rail 58 is moved by the guide rollers 64a, 64b,
It goes without saying that this is done by rolling 66a and 66b.

As described above, according to the present invention, the gripping mechanism for gripping the change knob is connected to the change arm via the arm member so that its position can be adjusted, so that the work of attaching and positioning the change lever operating device is simplified. ,Moreover,
It has the advantage that it can be done in a short time.

Further, as a result of configuring the gripping mechanism to be gripped by the change knob rather than the change shaft, automatic operation can be easily performed even when a cover or the like is attached to the change lever itself. In addition, even if you need to reposition the device body once due to the occurrence of some situation, it is possible to do so easily.
It is possible to prevent an inefficient situation as in the prior art, and therefore, the effect of further increasing the efficiency of the installation adjustment work can be obtained.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments.
Of course, various improvements and changes in design are possible without departing from the gist of the present invention.
