Description

  The present invention provides a drive robot (automatic driving device) for performing an endurance test on an internal combustion engine, a transmission, etc. of an automobile, in order to transmit the operating force of an operating arm of a shift lever actuator that drives the shift lever to the shift lever. The present invention relates to a shift lever knob gripping mechanism for a drive robot that is attached so as to cover the knob of the lever and is interposed between a knob operating portion provided at the tip of the operating arm of the shift lever actuator.

As a shift lever knob holding mechanism for a drive robot capable of reliably holding the knob regardless of the shape of the shift lever knob, for example, the one shown in FIGS. 8 to 10 is known. As shown in FIG. 8, the shift lever knob gripping mechanism 101 is formed in a cylindrical shape whose upper end is closed, and a cylindrical portion 102 that covers the knob 202 of the shift lever 201 and an inner portion of the cylindrical portion 102. A support portion 103 provided on the peripheral side and interposed between the knobs 202 to press and grip the knob 202 from the surroundings by elastic deformation. As shown in FIG. 9, the shift lever knob gripping mechanism 101 has the cylindrical portion 102 mounted in a cylindrical knob operating portion 204 provided at the tip of the operating arm 203 of the shift lever actuator. The operating force of the operating arm 203 is transmitted to the shift lever 201 via a cylindrical knob operating portion 204, a cylindrical portion 102, and an elastic support portion 103 arranged in the cylindrical portion 102. . (For example, patent document 1).

  By the way, the shift lever knob gripping mechanism 101 is configured to grip the knob 202 by pressing the knob 202 from the periphery with the support portion 103. Therefore, even if the thickness of the knob 202 is slightly different, While there is an advantage that the knob 202 can be gripped by using the elasticity of the support portion 103, the shift lever knob gripping mechanism 101 is positioned relative to the knob 202 when the elastic gripping force of the support portion 103 is weak. There was a problem that it was easy to cause a shift.

  As shown in FIG. 9, a gap δ is set between the outer peripheral surface of the cylindrical portion 102 and the inner peripheral surface of the cylindrical knob operating portion 204. When the operation arm 203 is slid in the direction of arrow A, the gap δ is used to tilt the shift lever 201 as shown in FIG. In order to increase the operation stroke amount, the amount of the gap δ must be increased. If the amount of the clearance δ is increased, the stopping accuracy of the shift lever 201 becomes worse. It was.

A shift lever knob upper holding operation screw 16.

  The cap body 14 is formed in a so-called covered cylindrical shape by a cylindrical portion 14a and an end face plate 14b that closes one end side of the cylindrical portion 14a, and the open end side of the cylindrical portion 14a is the cylindrical main body. It has penetrated into the part 11.

  The outer peripheral surface 11 a of the cylindrical main body 11 is formed in a spherical shape, and is in line contact or point contact with the inner peripheral surface 5 a of the cylindrical knob operation unit 5.

  The plurality of shift lever knob lower portions 13 include a pressed surface 21 that is pressed by the cap body 14 on the upper end side. On the other hand, the cap body 14 closes the plurality of shift lever knob lower restraints 13 by pressing the pressed surface 21 when the amount of penetration into the cylindrical main body 11 is increased (arrow B). It is provided with a pressed surface pressing portion 22 on the lower end side that releases the pressing of the pressed surface 21 when rotated in the ′ direction to reduce the amount of penetration into the cylindrical main body portion 11.

  The cap body 14 includes a screw hole 14c into which the shift lever knob upper holding operation screw 16 is screwed into a central portion of the top plate 14b. Further, a male screw groove is formed on the outer peripheral surface of the cylindrical portion 14 a and is screwed into a female screw groove formed on the inner peripheral surface of the cylindrical main body portion 11. As described above, the cap body 14 is attached to the cylindrical main body 11 in a state where the cylindrical portion 14 a is intruded into the cylindrical main body 11.

The cylindrical knob operation unit 5 is attached to the outer frame 31 so as to be movable in the X (arrow AA ′) direction, and the outer frame 31 is movable in the Y direction. As a result, the shift lever 2 is moved in the X, Y (arrow CC ′) directions to change gears.

  Accordingly, even when the shift lever 2 is tilted by moving the operation arm 4 of the shift lever actuator in the direction of arrow A from the upright state of the shift lever 2 shown in FIG. 1, as shown in FIG. In addition, the width (diameter) D of the main body 11 having the spherical outer peripheral surface is kept constant (keep the same value as the state in which the shift lever 2 shown in FIG. 1 is upright) The operating force of the operating arm 4 is reliably transmitted to the shift lever 2.

  In the embodiment shown in the drawings, the cap body 14 is screwed to the upper end side of the cylindrical main body 11 and the cap body 14 is rotated to rotate the plurality of shift lever knob lower holding members 13. The cap body 14 is linearly moved with respect to the main body 11 by a method such as spline coupling, and the plurality of shift levers are pressed by the pressed surface pressing portions 22 of the cap body 14. You may make it the structure which presses the to-be-pressed surface 21 of the knob lower part holding | pressing 13, and rotates the said some shift lever knob lower part holding | maintenance 13. Further, by improving the shapes of the pressed surface 21 and the pressed surface pressing portion 22, the lower ends of the plurality of shift lever knob lower restraints 13 are automatically moved by rotating the cap body 14 in one direction. The lower ends of the plurality of shift lever knob lower holders 13 may be automatically closed by opening and rotating the cap body 14 in the other direction. In the embodiment shown in the drawings, the knob operating portion 5 is formed in a cylindrical shape so as to be in line contact with the spherical outer peripheral surface 11 a of the main body portion 11. The inner peripheral surface may be spherical and may be in surface contact with the spherical outer peripheral surface 11a of the main body 11.
