[First Embodiment]
(Overall configuration of input device)
In FIG. 1, reference numeral 1 indicating the whole schematically illustrates an input device including a typical power transmission mechanism according to the first embodiment. Although this input device 1 is not specifically limited, For example, it is used suitably for the touch panel which is an input means which outputs the input signal for controlling operation | movement of vehicle equipment, such as an air conditioner, an audio apparatus, a navigation apparatus, etc., for example. .

  The input device 1 according to the illustrated example is disposed in the periphery of the driver's seat such as a center console, for example, and is connected to the display via wiring. When the input device 1 is operated by touching the touch panel of the operation unit 10 with an operator's finger, for example, a position on the surface of the touch panel is detected by a touch sensor, and a position detection signal corresponding to this position indicates an item button on the display. It is configured as a remote operation type input device for selecting and determining.

  As shown in FIG. 1, the external appearance of the input device 1 is a resin-made operation unit 10 that can be pushed and a resin-made body that supports the operation unit 10 so as to be able to return via a return mechanism such as a spring (not shown). 20. The operation unit 10 is configured by assembling a resin base 11. A touch sensor substrate is accommodated in the base 11. This touch sensor substrate is, for example, a capacitance touch sensor that detects capacitance, and is connected to a connector mounted on the control substrate via a flexible flat cable.

  As shown in FIG. 1, a plurality of elastic engagement pieces 11 a,..., 11 a that engage with the inside of the body 20 extend in the push operation direction and are guided and moved to the inside of the body 20. A pair of guide pieces 11b and 11b for extending in the push operation direction. Further, a connecting piece 11c, which is a first connecting member interlocked with the reciprocating motion of the operation unit 10, extends in the push operation direction.

  As shown in FIG. 1, the operation unit 10 includes a stabilizer 12 that suppresses the tilting operation of the operation unit 10 during a push operation. Both ends of the stabilizer 12 are attached to the pair of guide pieces 11 b of the base 11, thereby suppressing an inclination operation around the axis of the connecting pin 45 a of the outer ring gear 45.

(Configuration of power transmission mechanism)
As shown in FIGS. 1 and 2, a power transmission mechanism 30 that presents a vibration stimulation operation feeling to the finger of an operator who pushes the touch panel of the operation unit 10 is incorporated in the body 20. . The power transmission mechanism 30 includes a motor 31 mounted on a control board and capable of rotating in the forward and reverse directions, and a planetary gear mechanism 40 that transmits the forward and reverse rotation of the motor 31 to the operation unit 10.

  As shown in FIGS. 1 and 2, the planetary gear mechanism 40 includes a sun gear 41 fixed to a motor shaft 32 of a motor 31 that can rotate forward and reverse, and a pair of planetary gears 42 and 42 that mesh with the sun gear 41. The planetary gear 42 is supported via a carrier pin 43 so as to be able to rotate and revolve, and the outer ring gear 45 meshes with the planetary gear 42.

  As shown in FIGS. 1 and 2, a connecting pin 45 a that is a second connecting member protrudes at an eccentric position of the flat surface of the outer ring gear 45. The connecting pin 45a is connected to a pin engaging portion 11d formed by cutting out at a side end portion of the connecting piece 11c of the base 11 so as to be interlocked.

  As shown in FIGS. 1 and 2, the connecting piece 11 c of the base 11 is a motion conversion member for changing the forward / reverse rotational motion of the motor 31 into the linear motion of the operation unit 10. 40 is configured to be reciprocally finely movable. The pin engaging portion 11d of the connecting piece 11c is formed in the rotation locus of the connecting pin 45a of the outer ring gear 45, and maintains the reference position of the operating surface of the operating portion 10.

  By the way, in the comparative power transmission mechanism in which the rotation of the motor 31 is transmitted to the operation unit 10 with the gear ratio of the planetary gear mechanism 40, the motor transmitted to the planetary gear mechanism 40 when the touch panel of the operation unit 10 is pushed. It is affected by 31 cogging torque.

  FIG. 4 shows an example of a reaction force curve acting on the operation unit 10 by one push operation in the power transmission mechanism of the comparative example. In the figure, the vertical axis represents the magnitude of the reaction force, and the horizontal axis represents the motor rotation angle corresponding to one stroke of the push operation.

  When the touch panel of the operation unit 10 is pushed, as shown in FIG. 4, the resistance of the push operation by the touch panel increases due to the influence of the cogging torque of the motor 31 transmitted to the planetary gear mechanism 40. This is unfavorable because it impairs the feeling.

  In view of this, the input device 1 according to the first embodiment does not reduce the cogging torque of the motor 31 itself, but mainly includes the planetary gear mechanism 40 that can eliminate the influence of the cogging torque of the motor 31. Yes. Therefore, the configuration of the input device 1 configured as described above illustrates a typical configuration example, and is not limited to the illustrated example.

  In the illustrated example, the meshing with the outer ring gear 45 serving as an input element and the planet carrier 44 serving as an output element in a state where the sun gear 41 is fixed can transmit the push operation of the operation unit 10. It is configured as an intermeshing input side gear mechanism. On the other hand, with the planetary carrier 44 fixed, meshing with the sun gear 41 as an input element and the outer ring gear 45 as an output element is a vibration-side gear mechanism that meshes with the operation unit 10 so that vibration can be transmitted. It is configured.

  As shown in FIG. 2, one end of a first stopper lever 50 that is a first rotation restricting member that restricts the rotation of the sun gear 41 is fixed to the eccentric position of the flat surface of the sun gear 41 so as not to rotate. ing. The stopper lever 50 is positioned near the other end of the stopper lever 50 so as to be in contact with a first stopper pin 51 that protrudes into the body 20. One end of a first compression coil spring 52, which is a first return spring for returning the rotation from the rotation position to the original position, is fixed.

  As shown in FIG. 2, the other end of the first compression coil spring 52 is fixed inside the body 20, and the first stopper lever 50 is moved to the first stopper by the spring force of the first compression coil spring 52. Always biased toward the pin 51. The first stopper lever 50, the first stopper pin 51, and the first compression coil spring 52 constitute a first rotation restricting means.

  On the other hand, at the eccentric position of the flat surface of the planet carrier 44, as shown in FIG. 2, one end of the second stopper lever 53, which is a second rotation restricting member for restricting the rotation of the planet carrier 44, is made unrotatable. It is fixed. The other end of the stopper lever 53 is positioned in contact with a second stopper pin 54 that protrudes into the body 20. One end of a second compression coil spring 55, which is a second return spring for returning the planet carrier 44 from the rotational position to the original position, is fixed to the other end portion of the stopper lever 53.

  The other end of the second compression coil spring 55 is fixed inside the body 20, and the second stopper lever 53 is always attached to the second stopper pin 54 by the spring force of the second compression coil spring 55. It is energized. The second stopper lever 53, the second stopper pin 54, and the second compression coil spring 55 constitute a second rotation restricting means.

  As shown in FIG. 2, each of the first stopper lever 50 and the second stopper lever 53 is disposed at a neutral position where the first stopper lever 50 and the second stopper lever 53 are in contact with the stopper pins 51 and 54. This neutral position is the stop position of the operation surface of the operation unit 10 before the push operation (hereinafter, referred to as the following) when the connecting pin 45a of the outer ring gear 45 is on a straight line connecting the rotation center of the motor shaft 32 and the rotation center of the planetary gear 42. Also referred to as “reference position”).

  As shown in FIG. 2 and FIG. 3A, the first stopper lever 50 has a first force applied by the first compression coil spring 52 when the operation unit 10 moves from the reference position in the push operation direction. Since the state of being in contact with the stopper pin 51 is maintained, the rotation of the sun gear 41 is restricted. On the other hand, the second stopper lever 53 is separated from the second stopper pin 54 against the spring force of the second compression coil spring 55, so that the planetary carrier 44 is allowed to rotate.

  On the contrary, as shown in FIGS. 2 and 3 (b), the first stopper lever 50 has the first stopper lever 50 when the operation unit 10 moves from the reference position to the side opposite to the push operation direction. Since it separates from the first stopper pin 51 against the spring force of the compression coil spring 52, the sun gear 41 is allowed to rotate. One of the second stopper levers 53 maintains the state of being in contact with the second stopper pin 54 by the spring force of the second compression coil spring 55, so that the rotation of the planet carrier 44 is restricted. .

  According to the planetary gear mechanism 40 configured as described above, as shown in FIG. 3A, the rotation of the sun gear 41 is restricted by the first stopper lever 50 and the planetary gear by the second stopper lever 53. By allowing the carrier 44 to rotate, an input transmission path which is a first power transmission path is configured through the outer ring gear 45, the planetary gear 42, and the planetary carrier 44.

  On the other hand, as shown in FIG. 3B, the sun gear 41 is allowed to rotate by the first stopper lever 50 and the rotation of the planet carrier 44 is restricted by the second stopper lever 53. The vibration transmission path which is the second power transmission path is configured through the planetary gear 42 and the outer ring gear 45.

  In this input transmission path, since the rotation of the sun gear 41 is regulated by the first stopper lever 50, the planetary gear 42 and the outer ring gear 45 are not affected by the cogging torque of the motor 31 without the rotation of the motor 31. Rotates at a gear ratio that is not affected. Therefore, although the sun gear 41, the planetary gear 42, and the outer ring gear 45 are always meshed, a configuration in which the cogging torque of the motor 31 during the push operation of the operation unit 10 is eliminated can be obtained.

(Operation of input device)
Next, the operation of the input device 1 configured as described above will be described.

  As shown in FIG. 3A, when the touch panel of the operation unit 10 is pushed, the operation unit 10 pushes the connection pin 45a of the outer ring gear 45 in the push operation direction via the pin engagement portion 11d of the connection piece 11c. Press. As the outer ring gear 45 rotates around the sun gear 41, the rotation of the outer ring gear 45 is transmitted to the planet carrier 44 via the planetary gear 42. As the planet carrier 44 rotates, the second stopper lever 53 separates from the second stopper pin 54 against the spring force of the second compression coil spring 55.

  Since the rotation of the sun gear 41 is regulated by the first stopper lever 50 as shown in FIG. 3A, the motor 31 and the sun gear 41 do not rotate. Therefore, while the rotation of the motor 31 and the sun gear 41 is stopped, the planetary gear 42 and the outer ring gear 45 move the operation unit 10 in the push operation direction with a gear ratio that is not affected by the cogging torque of the motor 31. Move.

  When the push operation by the touch panel of the operation unit 10 is released, the planetary gear 42 and the outer ring gear 45 are engaged with each other by the restoring force of the second compression coil spring 55 and rotate in the direction opposite to the push operation direction. The operation surface of the unit 10 is returned to the initial stop position as the reference position.

  On the other hand, when the sun gear 41 rotates by a predetermined amount from the reference position of the operation unit 10 to the side opposite to the push operation direction, the spring force of the first compression coil spring 52 is resisted as shown in FIG. The first stopper lever 50 moves away from the first stopper pin 51. The rotation of the sun gear 41 is transmitted to the outer ring gear 45 through the planetary gear 42.

  Since the rotation of the planet carrier 44 is regulated by the second stopper lever 53 as shown in FIG. 3B, the planetary gear 42 rotates around the carrier pin 43, but around the sun gear 41. Do not revolve. Therefore, the power of the motor 31 is transmitted to the operation unit 10 with the gear ratio of the sun gear 41, the planetary gear 42, and the outer ring gear 45 while the rotation of the planet carrier 44 is stopped.

  The pin engaging portion 11d of the connecting piece 11c of the operating portion 10 is pressed against the push operation direction by the connecting pin 45a of the outer ring gear 45 as the sun gear 41, the planetary gear 42, and the outer ring gear 45 rotate. Therefore, the operation unit 10 moves in the direction opposite to the push operation direction. When the motor 31 rotates by a predetermined amount, a tactile sense presenting state is presented in which a tactile sensation is presented to the operation unit 10.

  When the rotation of the motor 31 is released, the restoring force of the first compression coil spring 52 causes the sun gear 41, the planetary gear 42, and the outer ring gear 45 to rotate in the push operation direction while meshing with each other. The operation surface is returned to the initial stop position as the reference position.

  Accordingly, the connecting piece 11c of the base 11 can be finely reciprocated by the rotational force of the motor 31 via the connecting pin 45a of the outer ring gear 45. Due to the vibration of the operation unit 10, feedback is given as tactile information in a direction perpendicular to the finger of the operator.

(Effects of the first embodiment)
In the input device 1 according to the first embodiment configured as described above, although the gears constituting the planetary gear mechanism 40 are always meshed, the motor 31 at the time of the push operation of the operation unit 10 is Since there is no cogging torque, the following effects can be obtained in addition to the above effects.

(1) The reaction force (resistance force) of the push operation of the operation unit 10 caused by the cogging torque of the motor 31 can be eliminated.
(2) The influence of the cogging torque of the motor 31 can be removed, and a good operational feeling of the operation unit 10 can be obtained.
(3) It is possible to realize a push operation that does not generate impact sound or vibration associated with cogging torque.
(4) Since the gears constituting the planetary gear mechanism 40 are always meshed with each other, the response of the operation unit 10 to vibration can be improved.
(5) It is possible to realize both the operation function and the tactile sense presentation function.

[Second Embodiment]
Referring to FIG. 5, one configuration example of the input device including the power transmission mechanism according to the second embodiment is schematically shown. In the second embodiment, except for the configuration using the first rotation restricting means for restricting the rotation of the sun gear 41 and the second rotation restricting means for restricting the rotation of the planet carrier 44, The configuration is the same as that of the first embodiment. Therefore, by using the same member code as the member code used in the first embodiment, detailed description about the member is omitted.

  In FIG. 5, a semicircular arc-shaped first guide hole 41 a is formed on the circumference around the motor shaft 32 at the eccentric position of the flat surface of the sun gear 41. A first compression coil spring 46 that is curved in a semicircular arc shape is accommodated in the guide hole 41 a, and the first compression coil spring 46 that is formed so as to protrude into the body 20 through the first compression coil spring 46. The return pin 56 is configured as a first rotation restricting member that restricts the rotation of the sun gear 41.

  When the operation surface of the operation unit 10 is in the initial stop position as the reference position, the first return pin 56 is set at the circumferential end surface position of the first guide hole 41a, and the first compression coil spring The spring force of 46 is always biased toward the first return pin 56.

  On the other hand, as shown in FIG. 5, a semicircular arc-shaped second guide hole 41b is formed on the flat surface of the planetary carrier 44 on the circumference centered on the motor shaft 32. A second compression coil spring 47 that is curved in an arc shape is accommodated in the guide hole 41b. A second return pin 57 that protrudes into the body 20 through the second compression coil spring 47 is configured as a second rotation restricting member that restricts the rotation of the planet carrier 44.

  When the operation surface of the operation unit 10 is in the initial stop position as the reference position, the second return pin 57 is set at the circumferential end surface position of the second guide hole 41b, and the second compression coil spring. The spring force of 47 is always urged toward the second return pin 57.

  When the operation unit 10 moves from the reference position in the push operation direction, the first return pin 56 interferes with the circumferential end surface of the first guide hole 41 a of the sun gear 41, and thus the rotation of the sun gear 41 is restricted. To do. One second return pin 57 allows rotation of the planet carrier 44 by moving away from the circumferential end surface of the second guide hole 41b of the planet carrier 44 while contracting the second compression coil spring 47. Become.

  On the contrary, when the operation unit 10 moves from the reference position to the side opposite to the push operation direction, the first return pin 56 contracts the first compression coil spring 46 while the first guide hole 41a. The sun gear 41 rotates by moving away from the circumferential end face. One second return pin 41 b interferes with the circumferential end surface of the second guide hole 41 b of the planet carrier 44, and thus restricts the rotation of the planet carrier 44.

(Effect of the second embodiment)

(2) In the second embodiment, instead of the configuration in which the guide hole 41 a of the sun gear 41 and the guide hole 41 b of the planet carrier 44 are formed, for example, a return pin is provided on each of the sun gear 41 and the planet carrier 44. It is also possible to project 56, 57. In this case, the guide holes 41 a and 41 b and the compression coil springs 46 and 47 are provided inside the body 20 corresponding to the return pins 56 and 57.
(3) The motion conversion member that converts the forward / reverse rotational motion of the motor 31 into the linear motion of the operation unit 10 is not particularly limited. For example, the connection that connects the operation unit 10 and the outer ring gear 45 in a freely interlocking manner. Instead of the pins 45a, other connecting members such as rollers can be used.
(4) It is needless to say that the input device 1 can be applied not only to in-vehicle devices but also to various electronic / electrical devices.
(5) Even with various switch devices that do not include a touch panel, it is possible to present a tactile stimulus operation feeling to an operator's finger, and for example, the present invention can also be applied to a mouse device, an operation knob, and the like.
