Description

  The present invention relates to an input device to which an operating force is input.

  Conventionally, for example, Patent Document 1 discloses an input device that includes an operation knob to which an operation force is input and a main body that supports the operation knob so that the operation knob can be moved by the input of the operation force. The input device further includes two voice coil motors. Each of the two voice coil motors has a pair of magnets that form magnetic poles and voice coils (first and second coils) that allow magnetic flux generated by the magnets to pass therethrough, and functions as an actuator. . In the two voice coil motors, each electromagnetic force generated by applying a current to each voice coil acts on the operation knob as an operation reaction force in a direction orthogonal to each other, and makes the user feel the operation reaction force through the operation knob. It is like that.

  In Patent Document 1, one end side of each yoke provided in each voice coil is connected by a connecting portion, and the magnetic flux generated in one voice coil is guided to the other voice coil, and in the other voice coil. There is provided a magnetic path forming body for guiding the generated magnetic flux to one of the boil coils to form a magnetic circuit. Thereby, the density of the magnetic flux which passes each voice coil can be improved, and it is trying to raise each electromagnetic force, ie, an operation reaction force, suppressing the usage-amount of forming material.

Japanese Patent Laying-Open No. 2015-125552

  In the input device described in Patent Document 1, when the yoke cannot be horizontally arranged when it is mounted on a predetermined part, and the yoke is inclined, the operation knob and the voice coil motor have their own weights. A downward force is applied along the plate surface direction of the yoke. Therefore, in such a case, the operation knob is moved downward by a downward force. Further, since the downward force is applied, the operation feeling is different between the upward operation and the downward operation, and the operator feels uncomfortable.

  Therefore, in the previous Japanese Patent Application No. 2015-106736, the present inventors provide a magnetic resistance in the yoke so that an acting force (stabilizing force) for stabilizing the magnetic circuit is generated with respect to the magnetic resistance. It was proposed that this acting force be in the opposite direction to the falling direction of the yoke due to the inclined arrangement. As a result, the force in the falling direction of the dead weight is canceled by the applied force, and the influence of the downward force due to the dead weight can be suppressed.

  However, the one provided with the above-described magnetic resistance can cope with a predetermined inclination angle, and cannot cope with the case where correspondence with various inclination angles is required.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an input device that can suppress the influence of downward force due to its own weight even when it is arranged at various inclination angles. Is to provide.

  In order to achieve the above object, the present invention employs the following technical means.

In the present invention, in the input device, an input unit (70) to which an operation force in a direction along the virtual operation plane (OP) is input;
A support portion (50) that supports the input portion so as to be movable along the operation plane by inputting an operation force;
Electromagnetic force generated by applying a current to the first coil, the first magnetic pole forming portion (61, 62) that forms the magnetic pole, and the first coil (41) through which the magnetic flux generated by the first magnetic pole forming portion passes. A first actuator (39x) that causes (EMF_x) to act on the input unit as an operation reaction force (RF_x) in a first direction along the operation plane;
Electromagnetic force generated by applying a current to the second coil, the second magnetic pole forming portion (63, 64) forming the magnetic pole, and the second coil (42) through which the magnetic flux generated by the second magnetic pole forming portion passes. A second actuator (39y) that causes (EMF_y) to act on the input unit as an operation reaction force (RF_y) in a second direction along the operation plane and intersecting the first direction;
The magnetic circuit (65) for the magnetic flux generated by the first and second magnetic pole forming portions is formed so as to sandwich the first magnetic pole forming portion (61, 62) and the second magnetic pole forming portion (63, 64). A fixed yoke (51), and movable yokes (71, 72), and one of the first and second actuators is arranged to be inclined with respect to the other, and
A magnetic resistance (71c, 72c) serving as a resistance in the magnetic circuit is provided in any of the fixed yoke and the movable yoke,
The movable yoke generates a stabilizing force so that the magnetic circuit is stabilized against the magnetic resistance,
The magnetic resistance is arranged so that the direction of action of the stabilizing force is opposite to the direction in which the movable yoke falls due to the inclined arrangement,
An adjustment section (77) that can adjust the magnitude of the magnetic resistance is provided.

  In general, in a magnetic circuit, a force (stabilizing force) acts in a direction in which the resistance of the magnetic path around the magnetic pole forming portion via the fixed yoke and the movable yoke decreases. The resistance of the magnetic path decreases as the area of the magnetic path increases. Therefore, an acting force (stabilizing force) is generated with respect to the movable yoke so as to increase the area of the magnetic path, that is, in a direction in which magnetic flux leakage increases.

  Then, due to the arrangement of the magnetic resistance, the direction of action of the stabilizing force is opposite to the falling direction of the movable yoke due to the inclined arrangement, that is, upward. Therefore, this upward force can counter the downward force generated by its own weight during the tilting arrangement, so that it is possible to suppress the influence of the downward force due to its own weight even when it is inclined. Become.

  In the present invention, the magnitude of the magnetic resistance can be adjusted by the adjustment unit (77) according to each inclination angle even when the inclination angle when the input device is inclined is variously set. Therefore, it is possible to balance the force in the falling direction of the dead weight and the upward force, and the influence of the downward force due to the dead weight can be suppressed.

And the combination where the structure described in several embodiment and the modification is not specified shall also be disclosed by the following description.

(First embodiment)
An operation input device 100A according to the first embodiment of the present invention shown in FIG. 1 is mounted on a vehicle and includes a display system 10 together with a display in the vehicle interior, for example, a navigation device 20 or a head-up display device 120 (see FIG. 2). It is composed. As shown in FIG. 2, the operation input device 100 </ b> A is installed at a position adjacent to the palm rest 19 at the center console of the vehicle, and exposes the operation knob 73 in a range that can be easily reached by the operator. The operation knob 73 is displaced in the direction of the input operation force when the operation force is input by the operator's hand H or the like.

  As shown in FIG. 3, the operation input device 100A is inclined at an inclination angle θ such that one of the first voice coil motor 39x and the second voice coil motor 39y, which will be described later, is below the other. Has been placed. Here, one is the first voice coil motor 39x and the other is the second voice coil motor 39y. The inclination angle θ is set according to the vehicle on which the operation input device 100A is mounted. Alternatively, the inclination angle θ can be set differently depending on the operator's preference.

  The navigation device 20 is installed in the instrument panel of the vehicle and exposes the display screen 22 toward the driver's seat. The display screen 22 displays a plurality of icons associated with a predetermined function, a pointer 80 for selecting an arbitrary icon, and the like. When a horizontal operation force is input to the operation knob 73, the pointer 80 moves on the display screen 22 in a direction corresponding to the input direction of the operation force. As shown in FIGS. 1 and 2, the navigation device 20 is connected to a communication bus 90 and is capable of network communication with the operation input device 100 </ b> A and the like. The navigation device 20 includes a display control unit 23 that draws an image displayed on the display screen 22 and a liquid crystal display 21 that continuously displays the image drawn by the display control unit 23 on the display screen 22.

  Each configuration of the operation input device 100A will be described in detail. As shown in FIG. 1, the operation input device 100A is connected to a communication bus 90, an external battery 95, and the like. The operation input device 100 </ b> A can communicate with the navigation device 20 located remotely via the communication bus 90. The operation input device 100 </ b> A is supplied with electric power necessary for the operation of each component from the battery 95.

  The operation input device 100A is electrically configured by a communication control unit 35, an operation detection unit 31, a reaction force generation unit 39, a reaction force control unit 37, an operation control unit 33, and the like.

  The communication control unit 35 outputs information processed by the operation control unit 33 to the communication bus 90. In addition, the communication control unit 35 acquires information output from another in-vehicle device to the communication bus 90 and outputs the information to the operation control unit 33.

  The operation detection unit 31 detects the position of the operation knob 73 (see FIG. 2) moved by the input of the operation force. The operation detection unit 31 outputs operation information indicating the detected position of the operation knob 73 to the operation control unit 33.

  The reaction force generating unit 39 is configured to generate an operation reaction force on the operation knob 73 and includes an actuator such as a voice coil motor. The reaction force generation unit 39 applies so-called reaction force feedback to the operation knob 73 (see FIG. 2) when the pointer 80 (see FIG. 2) overlaps the icon on the display screen 22, for example, so-called reaction force feedback. As a result, a tactile sensation of a pseudo icon is caused to the operator.

  The reaction force control unit 37 is configured by, for example, a microcomputer for performing various calculations. The reaction force control unit 37 controls the direction and strength of the operation reaction force applied from the reaction force generation unit 39 to the operation knob 73 based on the reaction force information acquired from the operation control unit 33.

  The operation control unit 33 is configured by, for example, a microcomputer for performing various calculations. The operation control unit 33 acquires operation information detected by the operation detection unit 31 and outputs the operation information to the communication bus 90 through the communication control unit 35. In addition, the operation control unit 33 calculates the direction and strength of the operation reaction force applied to the operation knob 73 (see FIG. 2), and outputs the calculation result to the reaction force control unit 37 as reaction force information.

  As illustrated in FIG. 3, the operation input device 100 </ b> A is mechanically configured by a movable portion 70, a fixed portion 50, and the like.

  The movable part 70 has a pair of movable yokes 71 and 72 described later, the operation knob 73, a knob base 74, and a slider 75. The movable portion 70 is provided so as to be relatively movable with respect to the fixed portion 50 in the x-axis direction and the y-axis direction along the virtual operation plane OP. The movable unit 70 has a range in which the movable unit 70 is movable in the x-axis direction and the y-axis direction defined in advance by the fixed unit 50. When the movable part 70 is released from the applied operating force, the movable part 70 returns to the reference position as a reference.

  The knob base 74 is formed like a shaft member on the operation knob 73 and extends into a housing 50a of the fixed portion 50 described later. The knob base 74 is integrally connected to the operation knob 73 and can be moved together with the operation knob 73. The knob base 74 is connected to movable yokes 71 and 72 and a slider 75.

  The slider 75 is a plate-like member and is connected to the knob base 74 so as to be adjacent to the operation knob 73. The plate surface of the slider 75 is disposed along the virtual operation plane OP. On the opposite side of the slider 75 from the operation knob 73, a plate-like receiving portion 50b constituting one of the fixed portions 50 is provided. The receiving portion 50 b is disposed so as to be parallel to the slider 75. The surface facing the receiving portion 50b at the end in the plate surface direction of the slider 75 is in contact with the receiving portion 50b, and the slider 75 moves (slids) with friction with respect to the receiving portion 50b. It has become.

  The frictional force generated in the slider 75 is determined by the gravity generated in the slider 75, the friction coefficient between the slider 75 and the receiving portion 50b, and the like.

  The fixed portion 50 includes a housing 50a, a receiving portion 50b, a circuit board, and the like, and holds a fixed yoke 51 described later. The housing 50a accommodates the components such as the receiving portion 50b, the circuit board, and the reaction force generating portion 39 while supporting the movable portion 70 so as to be relatively movable. The receiving portion 50b serves as a receiving plate when the slider 75 is moved, and is fixed in the housing 50a. The circuit board is fixed in the housing 50a in a posture in which the plate surface direction is along the operation plane OP. The circuit board is disposed, for example, so as to face the bottom surface (lower surface) of the housing 50a. A microcomputer or the like constituting the operation control unit 33 and the reaction force control unit 37 is mounted on the circuit board.

  Between the above movable part 70 and the fixed part 50, the reaction force generation part 39 shown in FIGS. 3-5 implements reaction force feedback. The reaction force generator 39 includes a first voice coil motor (VCM) 39x and a second VCM 39y that function as two sets of actuators, a fixed yoke 51, two movable yokes 71 and 72, and the like.

  The first VCM 39x includes a first coil 41, two magnets 61 and 62, a fixed yoke 51 (first coil side yoke portion 52), and movable yokes 71 and 72. The second VCM 39 y includes a second coil 42, two magnets 63 and 64, a fixed yoke 51 (second coil side yoke portion 53), and movable yokes 71 and 72. Hereinafter, the details of the coils 41 and 42, the magnets 61 to 64, the fixed yoke 51, and the movable yokes 71 and 72 will be described in order.

  Each of the coils 41 and 42 is formed by winding a wire made of a nonmagnetic material such as copper as a winding 49 into a flat cylindrical shape. In each of the coils 41 and 42, the cross section orthogonal to the winding axis direction of the winding 49 is formed in a rectangular shape. Each winding 49 is wound until the thickness of the cylindrical wall of each coil 41, 42 is about 3 mm, for example. In each coil 41, 42, accommodation chambers 41 a, 42 a extending in the winding axis direction are formed on the inner peripheral side of the wound winding 49. Each of the coils 41 and 42 is electrically connected to the reaction force control unit 37 via a wiring pattern provided on the circuit board, and a current is individually applied to each winding 49 by the reaction force control unit 37.

  The coils 41 and 42 are arranged along the y axis with a slight gap therebetween. Each of the coils 41 and 42 is fixed to a fixing part 50 such as a circuit board in a posture in which the winding axis direction of the winding 49 is along the operation plane OP. The winding axis direction of one coil (hereinafter “first coil”) 41 is along the x-axis. The winding axis direction of the other coil (hereinafter “second coil”) 42 is along the y-axis. Each coil 41, 42 forms a pair of coil side surfaces 41u, 41d, 42u, 42d along the operation plane OP, respectively. In each of the coils 41 and 42, one of the coils 41 and 42 facing the operation knob 73 side is defined as the upper coil side surface 41u and 42u, and the other facing the circuit board side (the bottom surface side of the housing 50a) is defined as the lower coil side surface 41d and 42d. Each coil side surface 41u, 41d, 42u, 42d is formed in a substantially quadrilateral shape with each side along the x-axis or y-axis.

  Each of the magnets 61 to 64 is a neodymium magnet or the like, and is formed in a substantially quadrangular plate shape having a longitudinal direction. The two magnets 61 and 62 are located away from each other in the z-axis direction substantially orthogonal to the operation plane OP, and are aligned in the z-axis direction. Similarly, the other two magnets 63 and 64 are located away from each other in the z-axis direction and are aligned in the z-axis direction. Each of the magnets 61 to 64 is provided with a magnetized surface 68 and a mounting surface 69 formed in a smooth flat shape. In each of the magnets 61 to 64, the magnetic poles of the magnetized surface 68 and the mounting surface 69 are different from each other (see also FIGS. 8 and 9).

  Each attachment surface 69 of the magnets 61 and 63 is attached to the movable yoke 71 in a posture in which the long side is along the x axis. The movable yoke 71 is a single plate-shaped member, and is formed so as to connect between the magnet 61 and the magnet 63 and corresponding regions.

  The magnetized surface 68 of the magnet 61 held by the movable yoke 71 is opposed to the upper coil side surface 41u of the first coil 41 with a predetermined interval in the z-axis direction. The magnetized surface 68 of the magnet 63 held by the movable yoke 71 faces the upper coil side surface 42u of the second coil 42 while leaving a predetermined interval in the z-axis direction.

  Each attachment surface 69 of the magnets 62 and 64 is attached to the movable yoke 72 in a posture in which the long side is along the x axis. Similar to the movable yoke 71, the movable yoke 72 is a single plate-shaped member, and is formed so as to connect the magnet 62 and the magnet 64 to the corresponding regions.

  The magnetized surface 68 of the magnet 62 held by the movable yoke 72 is opposed to the lower coil side surface 41d of the first coil 41 with a predetermined interval in the z-axis direction. The magnetized surface 68 of the magnet 64 held by the movable yoke 72 faces the lower coil side surface 42d of the second coil 42 with a predetermined interval in the z-axis direction.

  Each magnetized surface 68 in each of the magnets 61 to 64 is located at the center of each of the opposing coil side surfaces 41u, 41d, 42u, 42d when the movable portion 70 is returned to the reference position.

  In the above configuration, as shown in FIG. 8, the magnetic flux generated by each of the magnets 61 and 62 passes (penetrates) the winding 49 of the first coil 41 in the z-axis direction. Therefore, when a charge moves in the winding 49 placed in the magnetic field by applying a current to the first coil 41, a Lorentz force is generated in each charge. Thus, the first VCM 39x generates an electromagnetic force EMF_x in the x-axis direction (first direction) between the first coil 41 and the magnets 61 and 62. By reversing the direction of the current applied to the first coil 41, the generated electromagnetic force EMF_x is also reversed, and the direction is in the opposite direction along the x axis.

  As shown in FIG. 9, the magnetic flux generated by each of the magnets 63 and 64 passes (penetrates) the winding 49 of the second coil 42 in the z-axis direction. Therefore, when a charge moves in the winding 49 placed in the magnetic field by applying a current to the second coil 42, a Lorentz force is generated in each charge. Thus, the second VCM 39y generates an electromagnetic force EMF_y in the y-axis direction (second direction) between the second coil 42 and the magnets 63 and 64. By reversing the direction of the current applied to the second coil 42, the generated electromagnetic force EMF_y is also reversed, and the direction is in the opposite direction along the y-axis.

  The fixed yoke 51 is made of a magnetic material such as soft iron and electromagnetic steel plate. The fixed yoke 51 corresponds to the coil side yoke of the present invention. As shown in FIGS. 3 to 5, the fixed yoke 51 is provided with two coil side yoke portions 52 and 53 and a connecting portion 54. The coil side yoke parts 52 and 53 and the connection part 54 are formed in a flat plate shape.

  One coil side yoke part (hereinafter referred to as “first coil side yoke part”) 52 is inserted into the accommodation chamber 41a of the first coil 41 and penetrates the accommodation chamber 41a. First opposing surfaces 52a are formed on both surfaces of the first coil side yoke portion 52 accommodated in the accommodation chamber 41a. The two first facing surfaces 52a are located on the inner peripheral side of the first coil 41, and are arranged so as to sandwich the coil 41 from both the inner and outer sides together with the magnets 61 and 62 disposed on the outer peripheral side of the first coil 41. The magnets 61 and 62 are individually opposed to the magnetized surfaces 68. The magnetic flux generated by each of the magnets 61 and 62 induced in the first coil side yoke portion 52 passes (penetrates) the winding 49 of the first coil 41 in the z-axis direction.

  The other coil side yoke part (hereinafter, “second coil side yoke part”) 53 is inserted into the accommodation chamber 42a of the second coil 42 and penetrates the accommodation chamber 42a. A second opposing surface 53a is formed on both surfaces of the second coil side yoke portion 53 accommodated in the accommodation chamber 42a. The two second facing surfaces 53a are located on the inner peripheral side of the second coil 42, and are arranged so as to sandwich the coil 42 from both the inner and outer sides together with the magnets 63 and 64 disposed on the outer peripheral side of the second coil 42. The magnets 63 and 64 are individually opposed to the magnetized surfaces 68. The magnetic flux generated by each of the magnets 63 and 64 guided to the second coil side yoke portion 53 passes (penetrates) the winding 49 of the second coil 42 in the z-axis direction.

  Therefore, the first coil side yoke portion 52 in the fixed yoke 51 corresponds to the magnets 61 and 62, and the second coil side yoke portion 53 corresponds to the magnets 63 and 64. The first coil side yoke portion 52 and the second coil side yoke portion 53 are formed such that the areas corresponding to the magnets 61 and 62 and the magnets 63 and 64 are separated from each other.

  The connecting portion 54 is bent in an L shape along the coils 41 and 42. The connecting portion 54 extends from the first coil side yoke portion 52 accommodated in the first coil 41 to the second coil side yoke portion 53 accommodated in the second coil 42, thereby providing two coil side yoke portions 52. , 53 are connected. As described above, the fixed yoke 51 extending from the storage chamber 41a of the first coil 41 to the storage chamber 42a of the second coil 42 is formed. The coils 41 and 42 are integrally formed with the fixed yoke 51.

  Each of the movable yokes 71 and 72 is formed of a magnetic material such as soft iron and an electromagnetic steel plate, like the fixed yoke 51. Each of the movable yokes 71 and 72 is formed of a rectangular flat plate material and has substantially the same shape. The movable yokes 71 and 72 are arranged in parallel so as to face the both surface sides of the fixed yoke 51 (the first coil side yoke portion 52 and the second coil side yoke portion 53). Each of the movable yokes 71 and 72 is held (connected) to the knob base 74 so as to face each other while sandwiching the two coils 41 and 42 in the z-axis direction.

  Each movable yoke 71, 72 has a first holding surface 71a, 72a and a second holding surface 71b, 72b. One movable yoke 71 holds the mounting surface 69 of the magnet 61 by the first holding surface 71a and holds the mounting surface 69 of the magnet 63 by the second holding surface 71b. The other movable yoke 72 holds the mounting surface 69 of the magnet 64 by the second holding surface 72b while holding the mounting surface 69 of the magnet 62 by the first holding surface 72a.

  Therefore, the fixed yoke 51 and the movable yoke 71 are arranged so as to sandwich the magnets 61 and 63. Further, the fixed yoke 51 and the movable yoke 72 are arranged so as to sandwich the magnets 62 and 64.

  As shown in FIGS. 3 to 5, in this embodiment, the movable yokes 71 and 72 are provided with a magnetic resistance serving as a resistance in the magnetic circuit. The magnetic resistance is arranged so that the acting direction of the acting force (stabilizing force), which will be described later, is opposite to the direction in which the movable yokes 71 and 72 fall due to the inclined arrangement. Specifically, in the movable yokes 71 and 72, the magnetic resistance is lower in the inclined arrangement in the region where the region corresponding to the magnets 61 and 62 and the region corresponding to the magnets 63 and 64 are connected. It arrange | positions so that it may adjoin to the area | region corresponding to the magnets 61 and 62 of 1st VCM39x. That is, the magnetic resistance is provided in a region on the upper side of the inclination than the magnets 61 and 62.

  The magnetic resistance is a thinned portion provided in the movable yokes 71 and 72, and is here formed as holes 71c and 72c. The holes 71c and 72c are formed so as to form a rectangle having a long side in the x-axis direction.

  Further, as shown in FIGS. 6 and 7, the movable yokes 71 and 72 are provided with adjusting portions 77 that can adjust the magnitude of the magnetic resistance, respectively. The adjusting portion 77 is slid to adjust the area of the holes 71c and 72c serving as the magnetic resistance (thinning portion), thereby adjusting the magnitude of the magnetic resistance. The adjusting unit 77 may be provided on one of the movable yokes 71 and 72. The adjustment unit 77 is configured to include a slide mechanism that slides by an operator's manual operation, and includes, for example, a slide plate 77a, a slider block 77b, a shaft 77c, a stand 77d, a handle 77e, and the like. . Hereinafter, the adjustment part 77 provided in the movable yoke 71 will be described in detail as a representative example (FIGS. 6 and 7).

  Two slide plates 77 a are provided with respect to the hole 71 c and serve as plate members that slide along the plate surface of the movable yoke 71. The same material as that of the movable yoke 71 is used for the slide plate 77a. The two slide plates 77a are arranged so as to be aligned in the x-axis direction (long-side direction) of the hole 71c. When the two slide plates 77a are arranged in contact with each other, the entire hole 71c can be covered.

  Two slider blocks 77b are provided so as to correspond to the respective slide plates 77a, and serve as members that slidably support the slide plates 77a. One end of the slider block 77b is connected to each slide plate 77a, and the other end is formed with a female screw that is screwed into the male screw of the shaft 77c. Of the two slider blocks 77b, the female screw of one slider block 77b is a female screw in the forward rotation direction, and the female screw of the other slider block 77b is a female screw in the reverse rotation direction.

  The shaft 77c is formed so as to extend in the x-axis direction, and is disposed adjacent to the hole 71c so as to be aligned in the y-axis direction. A male screw in the forward rotation direction is formed from the center position in the longitudinal direction of the shaft 77c toward one end side, and a male screw in the reverse rotation direction is formed from the center position in the longitudinal direction toward the other end side.

  The stand 77d is a support member that rotatably supports both ends of the shaft 77c. The handle 77e is provided on one end side of the shaft 77c, and the shaft 77c is rotated when the operator rotates the handle 77e.

  In the adjustment unit 77, when the handle 77e is rotated in one direction by the operator, for example, two slides are generated by a combination of a male screw and a female screw in the forward rotation direction and by a combination of a male screw and a female screw in the reverse rotation direction. The plate 77a slides away from each other so that the opening area of the hole 71c is set to be sequentially larger. On the contrary, when the handle 77e is rotated in the reverse direction by the operator, the two slide plates 77a are slid so as to approach each other, so that the opening area of the hole 71c is set to be sequentially smaller.

  The fixed yoke 51 and the two movable yokes 71 and 72 described above form the magnetic circuit 65 of the reaction force generator 39 shown in FIGS. The magnetic circuit 65 guides the magnetic flux generated by the magnets 61 and 62 of the first VCM 39x to the second VCM 39y and has the shape of the magnets 63 and 64 of the second VCM 39y by the shape surrounding the fixed yoke 51 and the movable yokes 71 and 72. The generated magnetic flux is guided to the first VCM 39x.

  Specifically, in the magnets 61 and 62 of the first VCM 39x shown in FIGS. 8 to 10, the magnetic poles of the magnetized surfaces 68 facing the first coil 41 are the same. Therefore, the directions of the magnetic fluxes generated by the magnets 61 and 62 are opposite to each other along the z axis. Therefore, the magnetic flux which goes to each 1st holding surface 71a, 72a from each 1st opposing surface 52a arises. These magnetic fluxes enter the respective movable yokes 71, 72 from the respective first holding surfaces 71a, 72a, and are directed from the first holding surfaces 71a, 72a to the second holding surfaces 71b, 72b in the respective movable yokes 71, 72. .

  Further, in each of the magnets 63 and 64 of the second VCM 39y shown in FIGS. 9 and 10, the magnetic poles of the respective magnetized surfaces 68 facing the second coil 42 are the same as each other and are opposed to the first coil 41. It is different from the magnetic pole of one magnetized surface 68 (see also FIG. 8). Therefore, the direction of the magnetic flux generated by each of the magnets 63 and 64 is a direction facing each other along the z axis. Therefore, the magnetic flux which goes to each 2nd opposing surface 53a arises from each 2nd holding surface 71b, 72b. As described above, the magnetic flux induced by each of the movable yokes 71 and 72 enters the second coil side yoke portion 53 from each second facing surface 53a, passes through the connecting portion 54, and then enters the first coil side yoke portion 52. Head. And the magnetic flux induced | guided | derived in the fixed yoke 51 goes to each 1st holding surface 71a, 72a (refer FIG. 8) again from each 1st opposing surface 52a.

  As described above, in the reaction force generation unit 39 shown in FIGS. 8 to 10, the magnetic flux generated by the magnets 61 and 62 in the first VCM 39x not only passes through the first coil 41 of the VCM 39x but is also guided by the magnetic circuit 65. As a result, the second coil 42 of the second VCM 39y is passed. Similarly, the magnetic flux generated by each of the magnets 63 and 64 in the second VCM 39y not only passes through the second coil 42 but also passes through the first coil 41 of the first VCM 39x by being guided by the magnetic circuit 65.

  Therefore, the magnetic flux density between each first opposing surface 52a and each first holding surface 71a, 72a and the magnetic flux density between each second opposing surface 53a and each second holding surface 71b, 72b are both VCM 39x, Compared with the form in which the magnetic circuit of 39y is formed individually, it becomes higher. In this way, the magnetic flux EMF_x that can be generated by the first VCM 39x is increased by improving the magnetic flux density penetrating the winding 49 of the first coil 41 in the z-axis direction. Similarly, the electromagnetic force EMF_x that can be generated by the second VCM 39y is increased by improving the magnetic flux density penetrating the winding 49 of the second coil 42 in the z-axis direction. Therefore, it is possible to increase the operation reaction forces RF_x and RF_y that can act on the operation knob 73 of the movable portion 70 and, consequently, the operator, while suppressing the use amount of the forming material of each of the magnets 61 to 64.

  In addition, in the first VCM 39x of the first embodiment, the two magnets 61 and 62 and the respective first facing surfaces 52a face each other in the z-axis direction while sandwiching the winding 49 of the first coil 41 from both inside and outside. doing. Therefore, the magnetic attraction force attracting the first facing surface 52a facing one magnet 61 can cancel the magnetic attraction force attracting the first facing surface 52a facing the other magnet 62. Similarly, in the second VCM 39y, the magnetic attraction force that attracts the second facing surface 53a that the one magnet 63 faces can cancel the magnetic attraction force that attracts the second facing surface 53a that the other magnet 64 faces. By reducing the magnetic attractive force acting on the movable part 70 in this way, the movable part 70 can move smoothly by the input of the operation force by the operator.

  Next, the operation | movement which suppresses the influence of the downward force which generate | occur | produces with dead weight when operation input device 100A is inclinedly arranged (FIG. 3) is demonstrated using FIGS.

  As shown in FIG. 15, for example, the first VCM 39x is on the lower side, the second VCM 39y is on the upper side, and the tilt angle is θ. With such an arrangement, the operation input device 100 </ b> A generates a force of mg · sin θ as a downward force along the surface of the fixed yoke 51 when the weight of the movable portion 70 is mg.

  Here, first, as shown in FIGS. 11 to 13, it is assumed that the holes 71 c and 72 c and the adjustment portion 77 are not formed in the movable yokes 71 and 72.

  As shown in FIG. 12, the first coil side yoke portion 52 and the movable yoke 71 form a magnetic circuit for the magnetic flux (magnetic flux leakage) generated by the magnet 61, and the first coil side yoke portion 52 and the movable yoke 72 are The magnetic circuit for the magnetic flux generated by the magnet 62 (magnetic flux leakage) is formed. Similarly, the second coil side yoke portion 53 and the movable yoke 71 form a magnetic circuit for the magnetic flux (magnetic flux leakage) generated by the magnet 63, and the second coil side yoke portion 53 and the movable yoke 72 are formed by the magnet 64. A magnetic circuit for the generated magnetic flux (magnetic flux leakage) is formed.

  Generally, in these magnetic circuits, the resistance of the magnetic path around the magnets 61 and 63 through the fixed yoke 51 (the first coil side yoke portion 52 and the second coil side yoke portion 53) and the movable yoke 71, and The force acts in a direction in which the resistance of the magnetic path around the magnets 62 and 64 through the fixed yoke 51 (the first coil side yoke portion 52 and the second coil side yoke portion 53) and the movable yoke 72 becomes smaller. . The resistance of the magnetic path decreases as the area of the magnetic path increases. Therefore, an acting force is generated so that the area of the magnetic path is increased, that is, in the direction in which the magnetic flux leakage is increased. FIG. 12B shows the acting force generated on the second coil 42 side.

  In addition, one of the fixed yoke 51 and the movable yokes 71 and 72, here, the fixed yoke 51 is spaced from the areas corresponding to the magnets 61 and 62 and the magnets 63 and 64. That is, the first coil side yoke portion 52 and the second coil side yoke portion 53 are divided. Further, the other of the fixed yoke 51 and the movable yokes 71 and 72, here the movable yokes 71 and 72, are connected between the magnets 61 and 62 and the regions corresponding to the magnets 63 and 64. In such a case, as shown in FIG. 13, the acting force is directed to the opposite side to the second coil 42 on the first coil 41 side, and directed to the opposite side to the first coil 41 on the second coil 42 side. Both forces are balanced and apparently no force is generated.

  14 and 15, in the present embodiment, the other of the fixed yoke 51 and the movable yokes 71 and 72, here, the movable yokes 71 and 72 is on the lower side in the inclined arrangement. Magnetic resistances (thickening parts) serving as resistances in the magnetic circuit, that is, holes 71c and 72c are provided so as to be adjacent to regions (upper slopes) corresponding to the magnets 61 and 62 of the first VCM 39x.

  Due to the holes 71c and 72c, the area for forming the magnetic path is restricted in the magnets 61 and 62 of the first VCM 39x on the lower side, so that a force that increases magnetic flux leakage does not act. Become. On the other hand, on the second coil 42 side of the second VCM 39y on the upper side, an acting force that faces the opposite side of the first coil 41 is generated, and the acting force when viewed as a whole is the upward force in the inclined arrangement. It becomes power. The acting force (upward force) when viewed as a whole corresponds to the stabilizing force of the present invention. The upward force is opposite to the downward force (self-weight falling direction) generated by the weight of the inclined arrangement. Therefore, as shown in FIG. 15, since this upward force can counter the downward force, the influence of the downward force due to its own weight can be suppressed even when it is inclined.

  The upward force can be adjusted to the downward force by adjusting the vertical and horizontal dimensions (dimensions in the x and y directions) of the holes 71c and 72c according to the magnitude of the downward force due to its own weight. Can be balanced.

  Further, in order to suppress the influence of the downward force, as shown in FIG. 16 (a), the movable portion 70 actually has a frictional force F1 (upward) opposite to the downward force F due to its own weight. Therefore, the force obtained by adding the friction force F1 (upward) to the upward force F2 may be balanced with the downward force F due to its own weight. That is, F1 + F2> F and F2> F−F1.

  Further, in order to suppress the natural movement of the movable portion 70 by the upward force F2, as shown in FIG. 16B, the upward force F2 is a friction force F3 (downward) with respect to the upward force F2. And the downward force F may be made smaller. That is, F2 <F + F3.

  Here, in operation input device 100A, inclination angle θ at the time of mounting is set differently for different vehicles. Even in the same vehicle, there is a case where it is desired to change the setting of the inclination angle θ according to the preference of the operator. When the setting of the inclination angle θ is changed, the downward force changes as compared with the case of the predetermined inclination angle θ as described above, so that the balance with the upward force cannot be achieved.

  In this embodiment, the adjustment part 77 is provided in the hole 71c (72c), and the opening area of the hole 71c can be adjusted by the operator. By increasing the opening area of the hole 71c, the upward force can be increased. Conversely, by decreasing the opening area of the hole 71c, the upward force can be further reduced. .

  Therefore, even when the tilt angle θ when the operation input device 100A is tilted is variously set, the adjusting unit 77 determines the magnitude of the magnetic resistance (hole portion) according to each tilt angle θ. 71c), the downward force and the upward force can be balanced, and the influence of the downward force due to its own weight can be suppressed.

  In the first embodiment, the operation input device 100A corresponds to “input device” recited in the claims, and the first VCM 39x corresponds to “first actuator, one actuator” recited in the claims. The second VCM 39y corresponds to “the second actuator, the other actuator” recited in the claims. The fixed portion 50 corresponds to a “support portion” described in the claims, and the movable portion 70 corresponds to an “input portion” described in the claims. Further, the fixed yoke 51 corresponds to “one of the fixed yoke and the movable yoke” recited in the claims, and the movable yokes 71 and 72 correspond to “the fixed yoke and the movable yoke” described in the claims. It corresponds to “the other of them”. Further, the magnets 61 and 62 correspond to the “first magnetic pole forming portion” recited in the claims, and the magnets 63 and 64 correspond to the “second magnetic pole forming portion” recited in the claims. Further, the holes 71c and 72c correspond to the “magnetic resistance and thinning portion” described in the claims, and the slide plate 77a, the slider block 77b, the shaft 77c, the stand 77d, and the handle 77e are included in the claims. This corresponds to the “slide mechanism” described.

(Modification of the first embodiment)
FIG. 17 shows a first modification of the first embodiment, and FIG. 18 shows a second modification. Modification 1 and Modification 2 are adjustment parts 771a and 771b obtained by changing the slide plate 77a with respect to the adjustment part 77 of the first embodiment.

  As shown in FIG. 17, the adjustment unit 771a according to the first modification uses one slide plate 77a, and the slide plate 77a slides in the y-axis direction at the center of the hole 71c.

  In the adjustment part 771b of the second modification, as shown in FIG. 18, one slide plate 77a is used so that the slide plate 77a slides in the y-axis direction with respect to the entire hole 71c.

  Like the adjusting portions 771a and 771b, the number of the slide plates 77a, the size (area), the sliding direction, and the like can be variously changed. Similarly to the first embodiment, the opening of the hole 71c (72c) is possible. The area can be adjusted, and the same effect can be obtained.

(Second embodiment)
FIG. 19 shows an adjustment unit 772 of the operation input device 100B of the second embodiment. The adjustment part 772 of 2nd embodiment provides the spring 77f in the slide plate 77a. The spring 77f corresponds to the elastic member of the present invention.

  The slide plate 77a is, for example, a plate that can cover the entire hole 71c (72c) as in the second modification, and the upper surface of the movable yoke 71 (movable yoke 72) is y. It can slide in the axial direction. A downward force due to its own weight (force in the falling direction of its own weight) acts on the slide plate 77a.

  On the other hand, the spring 77f is disposed on the lower side of the sliding direction of the slide plate 77a, one end side is connected to the slide plate 77a, and the other end side is fixed to, for example, the receiving portion 50b. The spring 77f applies an urging force toward the upper side to the slide plate 77a.

  In the second embodiment, in accordance with the inclination angle θ when the operation input device 100B is mounted, the downward force acting on the slide plate 77a due to its own weight and the upward urging force by the spring 77f are balanced and inclined. The opening area of the hole 71c (72c) is automatically adjusted according to the change in the angle θ. That is, as the inclination angle θ increases, the opening area of the hole 71c increases, and the upward force (FIG. 15) described in the first embodiment increases. Conversely, the smaller the inclination angle θ, the smaller the opening area of the hole 71c, and the upward force (FIG. 15) becomes smaller.

  Therefore, even if the inclination angle θ is different, the upward force corresponding to the inclination angle θ at that time is automatically applied each time without the operator's operation as in the first embodiment. It can be generated and the influence of downward force due to its own weight can be suppressed.

(Third embodiment)
An operation input device 100C of the third embodiment is shown in FIGS. 3rd embodiment changes the setting position of a magnetic resistance (thickening part) with respect to said 1st embodiment. In the third embodiment, the magnetic resistance is a notch 51a.

  The cutout portion 51a is provided in one of the fixed yoke 51 and the movable yoke 71, here, the fixed yoke 51 (first coil side yoke portion 52) (one place). The notch 51a faces the magnets 61 and 62 in the movable yokes 71 and 72, and the direction in which the fixed yoke 51 and the movable yokes 71 and 72 overlap (the direction in which they are arranged), that is, the z-axis direction in FIG. When viewed from, the cutout portion 51 a is arranged so that a part of the cutout portion 51 a overlaps with the magnets 61 and 62. The notch 51 a is shifted downward with respect to the magnets 61 and 62 and is opened at the lower end of the first coil side yoke 52.

  As shown in FIG. 21, the dimension (width dimension) of the notch 51a is set in a range not exceeding the magnet 61 (62) regardless of the movable position of the magnet 61 (62) in the x-axis direction. Has been. Therefore, no matter how the magnet 61 (62) moves in the x-axis direction, the area where the notch 51a and the magnet 61 (62) overlap is always constant.

  An adjustment portion 773 is provided on the upper side surface of the first coil side yoke portion 52. Two slide plates 77a in the adjustment portion 773 are provided in the same manner as in the first embodiment, and can be slid in the x-axis direction by the operation of the operator so that the opening area of the notch portion 51a can be adjusted. It has become.

  In this embodiment, as shown in FIG. 22, the notch 51a increases the resistance of the magnetic path, so that the resistance of the magnetic path decreases, that is, as shown by the white arrow in FIG. An acting force (stabilizing force) is generated in the direction in which the area of the road increases. This acting force is an upward force in the inclined arrangement. Therefore, as in the first embodiment, the upward force can counter the downward force generated by its own weight during the tilting arrangement, so even if it is arranged in the tilting direction, the downward force due to its own weight The influence can be suppressed.

  And the adjustment part 773 is provided in the notch part 51a, and the opening area of the notch part 51a can be adjusted by the operator. By increasing the opening area of the notch 51a, the upward force can be increased, and conversely, by reducing the opening area of the notch 51a, the upward force can be further decreased. Can do.

  Therefore, even when the tilt angle θ when the operation input device 100C is tilted is variously set, the adjustment unit 773 adjusts the magnitude of the magnetic resistance (notch) according to each tilt angle θ. Since the opening area of the portion 51a can be adjusted, it is possible to balance the downward force and the upward force, and the influence of the downward force due to its own weight can be suppressed.

  In the present embodiment, the notch 51a may be provided in the fixed yoke 51 (second coil side yoke 53). That is, the notch 51a may be shifted to the lower side of the inclined arrangement with respect to the magnets 63 and 64 in the movable yokes 71 and 72 and opened at the lower end of the second coil side yoke 53. Good.

  Moreover, the notch 51a is good also as a hole which is not opened in the lower end part of the 1st coil side yoke part 52 (2nd coil side yoke part 53).

  Further, the dimension (width dimension) in the x-axis direction of the notch 51a (or hole) may be set larger than the dimension in the x-axis direction of the magnets 61 and 62 (63, 64).

(Other embodiments)
