Japanese Patent Laid-Open No. 9-220943

  When the operator operates the shift lever, some operators may feel that the moderation feeling of the shift lever is too strong or too weak. However, in the configuration of Patent Document 1, since the shift plate in which the guide groove having the moderation groove is formed is fixed, the operator cannot adjust the strength of the moderation feeling. For this reason, for example, when a disabled person or an elderly person with weak power operates the shift lever, the operability may be felt poor depending on the strength of the moderation.

  The present invention solves the above-described conventional problems, and an object of the present invention is to provide an operating device that allows an operator to adjust the degree of moderation when operating an operating lever.

The operating device of the present invention includes an operating lever supported so as to be swingable in a plurality of directions, a moderation mechanism portion that imparts a moderation feeling to the swinging operation force of the operation lever, and the moderation of the moderation mechanism portion It possesses a switching member for switching the intensity of feeling, and the detent mechanism includes a guide pin to swing together with the operating lever, a cam plate having a cam surface, urging to press the guide pins on the cam surface The position of the cam plate is adjusted by the operation of the switching member, and the relative position between the guide pin and the cam surface is adjusted .

  According to the operating device of the present invention, the moderation mechanism part gives a moderation feeling when the operation lever is swung, and the moderation feeling of the moderation mechanism part can be switched by the switching member. Therefore, the operator can adjust the moderation feeling of the operation lever according to his / her preference. For example, when a disabled person or an elderly person with weak force operates the operation lever, the operation lever can be operated with a weak force by operating the switching member so that the feeling of moderation is weakened.

  Since the operating device of the present invention can adjust the biasing force of the biasing member by adjusting the relative position of the cam surface with respect to the guide pin by operating the switching member, it is possible to adjust the degree of moderation.

  In the operating device of the present invention, for example, the cam plate is swingably supported by a support shaft, and the cam plate is provided with a pressing surface on a surface opposite to the cam surface. By pressing the pressing surface, the cam plate swings around the support shaft, and the relative position between the cam surface and the guide pin is adjusted.

  In this operation device, the relative position of the cam surface with respect to the guide pin can be changed by swinging the cam plate by the switching member.

  In the operating device of the present invention, an axis center line of the support shaft is oriented perpendicularly to a swinging direction of the operating lever.

  Preferably, the support shaft is located away from the swing center of the operation lever, and the support shaft and the cam surface are located on both sides of the swing region of the operation lever. .

  In the above configuration, when the contact point between the cam surface and the guide pin rotates about the support shaft, the direction of the tangent line passing through the contact point on the rotation locus can be made closer to the axial direction of the guide pin. Therefore, even if the position of the contact point between the cam surface and the guide pin changes due to the swing of the cam plate, the position shift of the operation position of the operation lever can be minimized.

  For example, in the operating device of the present invention, the pressing surface of the cam plate has different heights in a direction orthogonal to the support shaft, and the switching member is applied to different height positions of the pressing surface. By the contact, the position of the cam plate is changed stepwise.

  In the operating device of the present invention, it is preferable that an operating knob is fixed to the operating lever, and the switching member is disposed below the operating knob.

  By disposing the switching member below the operation knob, it is possible to prevent the switching member from being erroneously operated when switching of the moderation mechanism is unnecessary.

  According to the operating device of the present invention, the strength of moderation with respect to the swinging operation of the operating lever can be adjusted by the operation of the switching member by the operator. As a result, the operator can adjust the moderation feeling according to his / her preference.

The guide pin 15 is supported so as to protrude freely in a state where it is inclined at a predetermined angle with respect to the operation lever 2. Specifically, a hole 17a with a bottom is formed in the guide pin support portion 17, and the guide pin 15 is inserted into the hole 17a so as to be freely protruded. The guide pin 15 is urged in the protruding direction by a coil spring 16 housed in the hole 17a.

  The cam plate 30 is disposed between the guide member 40 and the guide pin 15. The cam plate 30 includes a substrate 31, and an insertion hole 32 through which the operation lever 2 is inserted is formed in the substrate 31.

  As shown in FIG. 3, the cam surface 33a has recesses Q1 to Q5 corresponding to the operation positions P1 to P5, respectively. FIG. 3 schematically shows the concave portions Q1 to Q5 formed below the cam member 33 by dotted lines so that the relationship with the operation positions P1 to P5 can be easily understood. The recesses Q1 to Q5 are each connected with a smooth curved surface. This curve is formed to have a curved surface that always returns the operating lever 2 to the operating position P1 when the operating force to the operating lever 2 is removed after moving to a position other than the operating position P1, which is the home position. ing.

  The guide pin 15 is pressed against the cam surface 33a by the biasing force of the coil spring 16. When the operation lever 2 is swung to the operation positions P1 to P5, the guide pin 15 is swung together with the operation lever 2. Accordingly, the head 15a of the guide pin 15 is inserted into the recesses Q1 to Q5 in accordance with the swinging operation of the operation lever 2, so that a sense of moderation is imparted to the swinging operation of the operation lever 2.

  The cam plate 30 is supported by a support shaft 34 installed on the housing 20 so as to be swingable in a third direction (Z1-Z2 direction: γ direction). The support shaft 34 is provided on a plate support portion 35 provided on the lower surface 30 a of the substrate 31 of the cam plate 30. The third axis center line Xg of the support shaft 34 extends in a direction (X1-X2) perpendicular to one of the swing directions of the guide pin 15 (here, the α direction).

  As shown in FIGS. 4A, 4B, and 4C, when the cam plate 30 is swung around the third axis center line Xg of the support shaft 34, the relative position of the cam surface 33a with respect to the guide pin 15 is increased. Change. Thereby, since the biasing force of the coil spring 16 can be adjusted, the strength of the moderation feeling of the operation lever 2 can be adjusted.

  As shown in FIGS. 4A, 4B, and 4C, when the cam plate 30 is swung, the contact point G between the recess Q1 of the cam surface 33a and the guide pin 15 is centered on the third axis center line Xg. Oscillates along an arc locus Φ (see FIG. 3). The support shaft 34 is disposed at a position away from the center of curvature 12 a of the sliding spherical surface 12, and the support shaft 34 and the contact point G are separated from each other in the Y direction across the operation region of the operation lever 2. Is arranged. Further, the support shaft 34 and the contact point G are arranged at substantially the same height in the Z direction. As a result, assuming a tangent passing through the contact point G in the arc locus Φ, both the tangent and the axial center line of the operation lever 2 are inclined in the same direction with respect to the Z direction. As a result, the position of the contact point G between the concave portion Q1 of the cam surface 33a and the guide pin 15 is shifted when the cam plate 30 is operated as compared with the case where the cam plate 30 is moved vertically in the Z1-Z2 direction. Can be reduced. Therefore, regardless of the position of the inclination of the cam plate 30, the operation positions P 1 to P 5 can be set to substantially the same position when the operation lever 2 is operated.

  In addition, by setting the third axis center line Xg of the support shaft 34 to a direction perpendicular to the swinging direction (α direction) of the guide pin 15 (operation lever 2), the recess Q1 of the cam surface 33a and the guide pin 15 Can be prevented from shifting in the α direction, which is the main swinging direction of the guide pin 15 (operation lever 2). As a result, the operation position of the operation lever 2 can be prevented from shifting regardless of the swing angle of the cam plate 30.

  On the upper surface (surface opposite to the cam surface 33a) 30b of the substrate 31 of the cam plate 30, a pressing member 19 having a plurality of (here, three) pressing surfaces 19a is provided. The pressing surface 19 a is pressed and supported by the switching member 18 against the urging force of the coil spring 16.

  The pressing surface 19a of the pressing member 19 has surfaces whose heights are different in the direction (Y1-Y2) perpendicular to the third central axis Xg of the support shaft 34. Here, the pressing surface 19a is composed of three surfaces having three levels of height that gradually increase from Y1 to Y2. Each of the three surfaces of the pressing surface 19a is connected by a smooth inclined surface. In the present embodiment, an example is given in which the pressing surface 19a is configured with three surfaces so that the degree of moderation can be adjusted in three stages.

  The switching member 18 for adjusting the moderation feeling of the operation lever 2 is slidably engaged with an elongated slide groove 42 formed in the guide member 40. The switching member 18 includes an operation portion 18a and a protruding portion 18b protruding below the operation portion 18a. The switching member 18 slides along the slide groove 42 with the operation portion 18a exposed to the upper side of the slide groove 42 and the protrusion 18b inserted into the slide groove 42 and protruding downward. Yes. At this time, depending on the slide position of the switching member 18, the tip of the protrusion 18b presses one of the three surfaces of the pressing surface 19a.

  Here, in the moderation mechanism unit having such a configuration, the operation when switching the moderation feeling strength will be described in more detail. 4A and 4B are operation explanatory views of the controller device 1. FIG. 4A shows the case where the strength of moderation is in the default state, and FIG. 4B shows the case where the strength of moderation is weaker than the default state. c) is a case where the strength of moderation is made stronger than the default state.

  Here, as shown in FIG. 4A, when the switching member 18 is pressing the central surface of the pressing surface 19a with the tip of the protruding portion 18b, the cam plate 30 has a default angle (here, the XY plane). The strength of moderation at this time is set to the default state. Note that the default state is not limited to this. One of the states shown in FIG. 4B and FIG. 4C may be set as the default state.

  As shown in FIG. 4B, when the switching member 18 is slid from the default state to the surface with the lower pressing surface 19a, the cam plate 30 swings upward (Z2 direction). To do. As a result, the cam plate 30 is tilted upward (Z2 direction), and the amount of protrusion of the guide pin 15 from the hole 17a increases. For this reason, the coil spring 16 is extended and the urging force is weakened. In this way, it is possible to weaken the sense of moderation when the operation lever 2 is swung to the operation positions P1 to P5.

  On the other hand, as shown in FIG. 4C, when the switching member 18 is slid from the default state to the surface having the higher pressing surface 19a, the cam plate 30 is moved downward (Z1 direction). Swing to tilt. As a result, the cam plate 30 tilts downward (in the Z1 direction), and the amount of protrusion of the guide pin 15 from the hole 17a decreases. For this reason, the coil spring 16 is compressed and the urging force is increased. In this way, it is possible to increase the moderation feeling when the operation lever 2 is swung to the operation positions P1 to P5.

  As described above, according to the operation device 1 of the present embodiment, the moderation mechanism unit can impart a moderation feeling to the swinging operation force to the operation positions P1 to P5 by the operation lever 2, and The level of moderation can be adjusted in three stages (default, strong, weak) by sliding the switching member 18. According to this, the operator can adjust the moderation feeling of the operation lever 2 according to his / her preference. As a result, for example, even when a disabled person or an elderly person with weak power operates the operation lever 2, the switching member 18 is slid so that the moderation feeling becomes weak, so that the operation lever 2 can be operated even with a weak force. Therefore, the operability can be improved.

  As shown in FIG. 3, an operation knob H is provided at the tip of the operation lever 2, and the switching member 18 is disposed so as to be hidden below the operation knob H. Thereby, it becomes easy to prevent the switching member 18 from being erroneously operated.

  In the above embodiment, the pressure surface 19a for adjusting the swing angle of the cam surface 33a is gradually increased from Y1 to Y2 so that the moderation feeling of the operation lever 2 can be adjusted in three stages. An example is given of a case where it is constituted by three surfaces having three levels of height. However, it is not restricted to this, You may comprise the press surface 19a so that it may have two surfaces or four or more surfaces.

  Further, the pressing surface 19a is not limited to the case where the pressing surface 19a is constituted by a plurality of surfaces as described above. For example, as shown in FIG. 5, the pressing surface 19a may be configured by a smooth inclined surface whose height gradually increases from Y1 to Y2. This also makes it possible to adjust the strength of the moderation eye of the operation lever 2 as described above. In addition, in this case, the strength of the moderate eye can be adjusted linearly.

  According to the configuration shown in FIG. 5, for example, the center of the surface of the pressing surface 19 a pressed by the switching member 18 is set to the default state, and the switching member 18 is slid so that the height of the pressing surface 19 a is lower. The cam plate 30 swings so as to tilt upward (Z2 direction). As the cam plate 30 is tilted upward (Z2 direction), the amount of protrusion of the guide pin 15 from the hole 17a increases, so that the coil spring 16 is extended and the biasing force is weakened. For this reason, it is possible to weaken the sense of moderation when the operation lever 2 is swung to the operation positions P1 to P5.

  On the other hand, the cam plate 30 swings so as to tilt downward (Z1 direction) as the switching member 18 is slid to a higher height of the pressing surface 19a. As the cam plate 30 is tilted downward (Z1 direction), the guide pin 15 decreases in the amount of projection of the guide pin 15 from the hole 17a, so that the coil spring 16 is compressed and the biasing force is increased. For this reason, it is possible to increase the moderation feeling when the operation lever 2 is swung to the operation positions P1 to P5.
