Input device Cross-reference to related applications

This application is based on Japanese Patent Application No. 2017-193008 filed on October 2, 2017, the contents of which are incorporated herein by reference.

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

As a conventional input device, for example, the one described in Patent Document 1 is known. The input device of Patent Document 1 forms each voice coil motor and two voice coil motors that generate operation reaction force in the x-axis direction and y-axis direction of the virtual operation plane in which the input unit (operation knob) is operated. A fixed yoke and a movable yoke which are disposed so as to sandwich the magnetism forming portion (magnet). The movable yoke is held by the input unit.

A magnetic resistance is provided to either the fixed yoke or the movable yoke, and a stabilizing force is generated in the movable yoke so as to stabilize the magnetic circuit against the magnetic resistance. When one of the voice coil motors is arranged to be on the lower side, the magnetic resistance is arranged such that the stabilizing force is generated in the direction opposite to the falling direction of the weight of the movable yoke (input unit). In this way, the influence of the downward force of its own weight is suppressed.

JP, 2016-167247, A

However, in the input device described in Patent Document 1, it is assumed that the vertical relationship in the inclined arrangement of the two voice coil motors is always fixed. On the other hand, for example, if the input device is used for a rotating body such as steering, the vertical relationship changes due to the rotation of the steering, so in the input device of Patent Document 1, the influence of inclination is Can not suppress.

An object of the present disclosure is to provide an input device which can be inclined and can suppress the influence of the downward force due to its own weight even when the vertical relation of the inclined arrangement changes. An input device according to an aspect of the present disclosure includes an input unit to which an operation force in a direction along a virtual operation plane is input, a slide plate fixed to a predetermined support unit and disposed parallel to the operation plane, A first actuator having a first coil having a first magnetic pole forming portion forming a magnetic pole and a first coil through which magnetic flux generated by the first magnetic pole forming portion passes; a second magnetic pole forming a magnetic pole And a second actuator having a second coil through which the magnetic flux generated by the forming portion and the second magnetic pole forming portion passes, and the first and second magnetic pole forming portions disposed so as to sandwich the first and second magnetic pole forming portions. A movable yoke that forms a magnetic circuit for generated magnetic flux; and a fixed yoke. The movable yoke is held by the input unit. The first electromagnetic force generated by the application of the current to the first coil is applied to the input portion as the first operation reaction force in the first direction along the operation plane via the movable yoke, and the current to the second coil A second electromagnetic force generated by the application is applied to the input unit as a second operation reaction force in a second direction crossing the first direction along the operation plane via the movable yoke. The sliding portion described above is pressed against the slide plate by pulling the movable yoke and the fixed yoke by the attraction force of the first and second magnetic pole forming portions. The frictional force generated between the slide plate and the sliding portion in accordance with the sliding is set to be larger than the self gravity force acting along the slide plate by the weight of the input portion and the movable yoke.

According to one aspect of the present disclosure, for example, the input device is mounted on a rotating body such as a steering device so that the input unit faces the operator, and the vertical relationship changes in an inclined posture and by rotation of the steering wheel. Even if you do, the friction force always overcomes the gravity. Therefore, regardless of how the vertical relationship of the input device changes, it is possible to suppress the influence of the downward force such as the input part sliding down.

As shown in FIG. 1, the navigation device 20 is connected to the communication bus 24 and is capable of network communication with the operation input device 100 and the like. The navigation device 20 has a display control unit 23 for drawing an image displayed on the display screen 22, and a liquid crystal display 21 for continuously displaying the image drawn by the display control unit 23 on the display screen 22.

As shown in FIG. 2, the operation input device 100 is installed, for example, on the spokes 26a of the steering 26 of the vehicle, and the operator (driver) holds the steering 26, for example, extends the thumb, An input operation to the operation knob 120 can be performed. The operation knob 120 is configured to be displaced in the direction of the input operation force when the operation force is input by the operator.

Since the operation input device 100 is mounted on the steering 26, as shown in FIG. 5, the operation input device 100 is disposed at an inclination angle θ so that the head 121 of the operation knob 120 faces the operator. In addition, the upper limit relation of the operation input device 100 in the inclined arrangement is not constant but is changed by rotating the steering 26. The inclination angle θ includes the case of 90 degrees.

Hereinafter, each configuration of the operation input device 100 will be described in detail. As shown in FIG. 1, the operation input device 100 is connected to the communication bus 24 and an external battery 25 or the like. The operation input device 100 can communicate with the remotely located navigation device 20 through the communication bus 24. Further, in the operation input device 100, the power necessary for the operation of each component is supplied from the battery 25.

The operation input device 100 is electrically configured by an operation detection unit 101, an operation control unit 102, a communication control unit 103, a reaction force control unit 104, a reaction force generation unit 105, and the like.

The operation detection unit 101 detects the position of the operation knob 120 (FIGS. 2 and 3) moved by the input of the operation force. The operation detection unit 101 outputs operation information indicating the detected position of the operation knob 120 to the operation control unit 102.

The operation control unit 102 is configured by, for example, a microcomputer for performing various calculations. The operation control unit 102 acquires the operation information detected by the operation detection unit 101, and outputs the operation information to the communication bus 24 through the communication control unit 103. In addition, the operation control unit 102 calculates the direction and strength of the operation reaction force applied to the operation knob 120, and outputs the calculation result to the reaction force control unit 104 as reaction force information.

The communication control unit 103 outputs the information processed by the operation control unit 102 to the communication bus 24. In addition, the communication control unit 103 acquires information output from the other on-vehicle apparatus to the communication bus 24 and outputs the information to the operation control unit 102.

The reaction force control unit 104 is configured by, for example, a microcomputer for performing various calculations. The reaction force control unit 104 controls the direction and strength of the operation reaction force applied from the reaction force generation unit 105 to the operation knob 120 based on the reaction force information acquired from the operation control unit 102.

The operation detection unit 101, the operation control unit 102, and the reaction force control unit 104 are mounted on a circuit board provided in a housing 110 described later.

The reaction force generation unit 105 is configured to cause the operation knob 120 to generate an operation reaction force. The reaction force generation unit 105 applies an operation reaction force to the operation knob 120, for example, when the pointer overlaps the icon on the display screen 22, so that an operator feels a pseudo icon with a so-called reaction force feedback. It is supposed to cause Details of the configuration of the reaction force generation unit 105 will be described later.

Next, the mechanical configuration of the operation input device 100 will be described. As shown in FIG. 3, the operation input device 100 includes a housing 110, an operation knob 120, a slide plate 130, a movable yoke 140, a fixed yoke 150, a first voice coil motor 161, a second voice coil motor 162, and the like. ing. The reaction force generation unit 105 is formed by the movable yoke 140, the fixed yoke 150, the first and second voice coil motors 161 and 162, and the like.

The housing 110 is, for example, a rectangular parallelepiped, and is a member that accommodates the portion excluding the head 121 of the operation knob 120.

The operation knob 120 is an input unit for the operator to perform an input operation, and includes a head 121, a shaft 122, a sliding portion 123, and the like. The operation knob 120 is operated along a virtual operation plane OP, and the first direction along the operation plane OP is along the x-axis direction (first direction) and along the operation plane OP. The direction (crossing direction) orthogonal to the direction is the y-axis direction (second direction). Further, the direction orthogonal to the x-axis direction and the y-axis direction (direction orthogonal to the operation plane OP) is the z-axis direction.

In the following description, in the z-axis direction, the operation knob 120 side of the operation input device 100 is referred to as "operation side", and the first and second coils 1611 and 1622 are referred to as "coil side". When the operating knob 120 is released from the operating force of the operator, the operating knob 120 is returned to the reference position as a reference.

The head 121 has a disk shape and is a portion exposed to the outside of the housing 110 on the operation side. The head 121 is a part to be subjected to an input operation when the operator directly touches, for example, a finger. The shaft portion 122 is a cylindrical portion extending from the center portion of the head portion 121 to the coil side inside the housing 110. Further, the sliding portion 123 has an arm portion extending in parallel to the operation plane OP from the middle portion of the shaft portion 122, and is a portion protruding toward the coil side at the tip end side of this arm portion.

The slide plate 130 is disposed in parallel with the operation plane OP, and is a plate member made of resin that receives the operation knob 120, and is fixed to the housing 110 (predetermined support portion). An opening having a predetermined area is formed at the central portion of the slide plate 130, and the tip end side of the shaft portion 122 of the operation knob 120 is inserted through the opening. The sliding portion 123 of the operation knob 120 is in contact with the surface of the slide plate 130 on the operation side. A predetermined amount of grease having a predetermined hardness is interposed between the slide plate 130 and the sliding portion 123 (described in detail later).

When the operation knob 120 is input, the sliding portion 123 slides along the slide plate 130. The movable area of the operation knob 120 (shaft portion 122) is defined by the set area of the opening of the slide plate 130.

The movable yoke 140 forms a part of a magnetic circuit with respect to the magnetic flux generated by the magnets 161a and 162a described later, and is a member forming a single flat plate. The movable yoke 140 is formed of, for example, a magnetic material such as soft iron and a magnetic steel plate, and is disposed on the coil side of the slide plate 130 so as to be parallel to the operation plane OP. A central portion on the operation side of the movable yoke 140 is held at an end of the shaft portion 122 of the operation knob 120. A predetermined gap is provided between the movable yoke 140 and the slide plate 130, and the movable yoke 140 is movable along with the operation knob 120 along the operation plane OP.

The fixed yoke 150 has a first fixed yoke 151 and a second fixed yoke 152. The fixed yoke 150, together with the movable yoke 140, forms a part of a magnetic circuit for the magnetic flux generated by the magnets 161a and 162a described later, and the first and second fixed yokes 151 and 152 are arranged in the y-axis direction. The member is formed to form a single flat plate. The fixed yoke 150 is formed of, for example, a magnetic material such as soft iron and an electromagnetic steel plate, and is disposed on the coil side of the movable yoke 140 so as to be parallel to the operation plane OP and fixed to the housing 110. .

The first fixed yoke 151 is a yoke corresponding to a first coil 1611 to be described later, and is, for example, a rectangular plate whose long side extends in the x-axis direction. The first fixed yoke 151 is arranged to correspond to one end of the movable yoke 140 in the y-axis direction.

The second fixed yoke 152 is a yoke corresponding to a second coil 1622 to be described later, and is, for example, a rectangular plate whose long side extends in the y-axis direction. The second fixed yoke 152 is disposed to correspond to the other end of the movable yoke 140 in the y-axis direction.

The first fixed yoke 151 and the second fixed yoke 152 may be connected to each other by the connecting portion at their respective predetermined end portions so as to be integrally formed.

The first voice coil motor 161 corresponds to a first actuator, and includes a magnet 161 a and a first coil 1611. Hereinafter, the first voice coil motor 161 will be referred to as a first VCM 161.

The magnet 161a is a first magnetic pole forming portion, and is, for example, a neodymium magnet or the like, and is formed in a substantially quadrilateral plate shape having a longitudinal direction. The longitudinal direction of the magnet 161a is in the x-axis direction. The magnet 161 a is disposed at one end of the movable yoke 140 in the y-axis direction, and is held on the coil side surface of the movable yoke 140. The magnet 161 a is disposed to face the first fixed yoke 151. Thus, the magnet 161 a is disposed so as to be sandwiched between the movable yoke 140 and the first fixed yoke 151. The magnetization direction of the magnet 161a is the z-axis direction.

The first coil 1611 is formed, for example, by winding a wire (winding) made of a nonmagnetic material such as copper in a flat cylindrical shape. In the first coil 1611, a cross section orthogonal to the axial direction of the winding is formed in a rectangular shape having a long side in the y-axis direction. The axial direction of the winding of the first coil 1611 is in the x-axis direction. In the first coil 1611, the first fixed yoke 151 of the fixed yoke 150 is inserted into the space portion on the inner peripheral side of the wound winding. Therefore, the first coil 1611 is a member fixed in position with the first fixed yoke 151. The first coil 1611 is disposed to face the magnet 161 a in the z-axis direction.

The second voice coil motor 162 corresponds to a second actuator, and has a magnet 162 a and a second coil 1622 similarly to the first voice coil motor 161. Hereinafter, the second voice coil motor 162 will be referred to as a second VCM 162.

The magnet 162a is a second magnetic pole forming portion, and is, for example, a neodymium magnet or the like, and is formed in a substantially quadrilateral plate shape having a longitudinal direction. The longitudinal direction of the magnet 162a is in the y-axis direction. The magnet 162 a is disposed at the other end of the movable yoke 140 in the y-axis direction, and is held by the coil side surface of the movable yoke 140. The magnet 162 a is disposed to face the second fixed yoke 152. Thus, the magnet 162 a is disposed so as to be sandwiched between the movable yoke 140 and the second fixed yoke 152. The magnetization direction of the magnet 162a is the z-axis direction. The attraction forces Fmag of the magnet 161a and the magnet 162a are set to be equal.

The second coil 1622 is formed, for example, by winding a wire (winding) made of a nonmagnetic material such as copper in a flat cylindrical shape. In the second coil 1622, a cross section orthogonal to the axial direction of the winding is formed in a rectangular shape having a long side in the x-axis direction. The axial direction of the winding of the second coil 1622 is directed to the y-axis direction. In the second coil 1622, the second fixed yoke 152 of the fixed yoke 150 is inserted into the space portion on the inner peripheral side of the wound winding. The second coil 1622 is a member fixed in position with the second fixed yoke 152. The second coil 1622 is disposed to face the magnet 162 a in the z-axis direction.

The configuration of the operation input device 100 according to the present embodiment is as described above, and the operation and effects thereof will be described below.

In the first VCM 161, the generated magnetic flux of the magnet 161a passes (penetrates) the winding of the first coil 1611 in the z-axis direction. The generated magnetic flux of the magnet 161 a flows so as to circulate among the magnet 161 a, the movable yoke 140, and the fixed yoke 150.

Then, when charge is moved in the winding placed in the magnetic field by application of current to the first coil 1611, Lorentz force is generated in each charge. Thus, the first VCM 161 generates a first electromagnetic force in the x-axis direction (first direction) between the magnet 161 a and the first coil 1611. By reversing the direction of the current applied to the first coil 1611, the generated first electromagnetic force is also reversed, resulting in a reverse direction along the x-axis. With the generation of the first electromagnetic force, the operation knob 120 receives the first electromagnetic force in the x-axis direction (first direction) along the operation plane OP in the direction opposite to the first electromagnetic force via the movable yoke 140. 1 Operation reaction force is generated.

Similarly, in the second VCM 162, the generated magnetic flux of the magnet 162a passes (penetrates) the winding of the second coil 1622 in the z-axis direction. The generated magnetic flux of the magnet 162 a flows so as to circulate between the magnet 162 a, the fixed yoke 150, and the movable yoke 140.

Then, when charge is moved in the winding placed in the magnetic field by application of current to the second coil 1622, Lorentz force is generated in each charge. Thus, the second VCM 162 generates a second electromagnetic force in the y-axis direction (second direction) between the magnet 162 a and the second coil 1622. By reversing the direction of the current applied to the second coil 1622, the generated second electromagnetic force is also reversed, resulting in a reverse direction along the y-axis. With the generation of the second electromagnetic force, the operation knob 120 is moved in the y-axis direction (second direction) along the operation plane in the opposite direction to the second electromagnetic force via the movable yoke 140. An operation reaction force is generated.

The operation detection unit 101 detects the position of the operation knob 120 associated with the input operation, and the operation control unit 102 performs the first and second operations based on the operation position of the operation knob 120 and the position of the pointer relative to the icon on the display screen 22. The direction and strength of the operation reaction force are calculated, and reaction force information is output to the reaction force control unit 104. Then, the reaction force control unit 104 controls the current applied to the first and second coils 1611 and 1622 based on the reaction force information.

As a result, the first and second operation reaction forces are generated in the operation knob 120, and the operator can obtain the tactile sensation of a pseudo icon by the reaction force feedback.

In the present embodiment, as shown in FIG. 4, in the operation input device 100, the magnets 161a and 162a and the first and second fixed yokes 151 and 152 are attracted to each other by the attraction force Fmag of the magnets 161a and 162a. ing. When the magnets 161a and 162a are attracted to the first and second fixed yokes 151 and 152, the movable yoke 140 and the operation knob 120 are also moved to the first and second fixed yokes 151 and 152. Accordingly, the sliding portion 123 is in a state of being pressed against the slide plate 130.

And in the state where operation input device 100 was installed in steering 26, as shown in Drawing 5, the whole operation input device 100 turns into an inclination posture. Here, a vertical force including the weight of the held movable yoke 140 acts on the operation knob 120 (black line arrow in FIG. 5). Due to the weight in the vertical direction, a gravity Ffall (force in the vertical direction × sin θ) along the slide plate 130 acts on the operation knob 120 (downward white arrow in FIG. 5).

On the other hand, since the sliding portion 123 is pressed against the slide plate 130, a frictional force Ffric against the self-gravity Ffall acts between the sliding portion 123 and the slide plate 130. In this embodiment, self-gravity Ffall <frictional force Ffric is set by adjusting the material selection of the grease provided between the sliding portion 123 and the slide plate 130 and the application amount in advance. . Furthermore, as a condition on the upper limit side of the frictional force Ffric, the frictional force Ffric <first and second operation reaction forces are set in advance.

As the material selection of grease, as shown in FIG. 6, for example, the selection based on the worked penetration indicating the hardness of the grease is possible. Then, on the basis of the procedure shown in FIG. 7, the actual friction force Ffric is adjusted by adjusting the worked penetration and application amount of the grease.

First, in step S100 in FIG. 7, the weight of the operation knob 120 including the movable yoke 140 is measured as the weight of the movable portion, and the gravity of Ffall obtained from weight × sin θ is the lower limit Fmin of friction force (= gravity of gravity Set as Ffall).

Next, in step S110, the upper limit value Fmax (= first and second operation force) of the frictional force is set from the target haptic feedback force.

Next, in step S120, grease of NLGI No 2 (intermediate hardness) is applied between the sliding friction surface, that is, between the sliding portion 123 and the slide plate 130.

Next, in step S130, the actual frictional force Ffric is measured using, for example, a push-pull gauge.

Then, in step S140, it is determined whether or not Fmin <frictional force <Fmax. If the condition is satisfied, the adjustment of the frictional force is ended.

However, if it is determined in step S140 that the result is no, the grease material is changed in step S150, and the grease application amount is changed in step S160, and step S140 is repeated. Note that either step S150 or step S160 may be performed on those performing step S150 and step S160 as described above after the negative determination in step S140.

As described above, in the present embodiment, the sliding portion 123 is pressed against the slide plate 130 by the movable yoke 140 and the fixed yoke 150 being pulled by the attraction force of the first and second magnets 161 a and 162 a. It is like that. In addition, the frictional force Ffric generated between the slide plate 130 and the sliding portion 123 is set larger than the gravity Ffall acting along the slide plate 130 by the weight of the operation knob 120 and the movable yoke 140. .

As a result, the operation input device 100 is mounted on a rotating body such as the steering 26 so that the operation knob 120 faces the operator, and the vertical relationship changes in the inclined posture with the rotation of the steering 26. Even if there is, the frictional force Ffric always overcomes the gravity Ffall. Therefore, regardless of how the vertical relationship of the operation input device 100 changes, it is possible to suppress the influence of the downward force such as the operation knob 120 sliding down.

In addition, since the frictional force Ffric is set smaller than the first and second operation reaction forces, the first and second operation reaction forces can not be obtained by the frictional force Ffric.

Further, by providing the magnets 161a and 162a between the movable yoke 140 and the fixed yoke 150 in combination of the movable yoke 140 and the fixed yoke 150 as one set, sliding is performed using the attraction force of the magnets 161a and 162a. It becomes possible to reliably press the portion 123 against the slide plate 130.

Second Embodiment
The operation input device 100A of the second embodiment is shown in FIG. In the second embodiment, the reaction force generation unit 105 is changed to a reaction force generation unit 105A in the operation input device 100 according to the first embodiment.

The reaction force generation unit 105A is obtained by adding a movable yoke 141 and magnets 161b and 162b to the reaction force generation unit 105 of the first embodiment. Here, the movable yoke 140 described in the first embodiment corresponds to the movable yoke on one side, and the magnets 161a and 162a held by the movable yoke 140 correspond to the first and second magnetic pole forming portions.

The movable yoke 141 and the movable yoke 140 are arranged in a pair so as to sandwich the fixed yoke 150. Similar to the movable yoke 140, the movable yoke 141 is held by the operation knob 120, and interlocks with the movable yoke 140. The movable yoke 141 corresponds to the movable yoke on the other side.

The magnet 161 b is held at one end of the operation-side surface of the movable yoke 141, and the magnet 162 b is held at the other end of the operation-side surface of the movable yoke 141. The magnet 161 b corresponds to the other first magnetic pole forming portion, and the magnet 162 b corresponds to the other second magnetic pole forming portion.

The attraction forces of the magnets 161 b and 162 b are set equal to each other, and are set to be different from the attraction forces of the magnets 161 a and 162 a. Specifically, the attraction of the magnets 161 b and 162 b is set to be smaller than the attraction of the magnets 161 a and 162 a.

In this embodiment, since the attraction forces of the magnets 161a and 162a overcome the attraction forces of the magnets 161b and 162b, the magnets 161a and 162a try to move to the fixed yokes 151 and 152 by the total attraction force, The sliding portion 123 is pressed against the slide plate 130 via the movable yoke 140.

Note that, by adding the movable yoke 141 and the magnets 161b and 162b to the first embodiment, the magnetic flux due to the magnets 161b and 162b can be increased, and the first and second operation reaction forces can be increased. it can. In other words, if the same first and first operation reaction forces as in the first embodiment are used, the current supplied to the first and second coils 1611 and 1622 can be reduced.

(Other embodiments)
In the above-described embodiments, the positional relationship between the movable yoke 140 and the fixed yoke 150 may be switched as long as a pressing force is generated on the sliding portion 123 with respect to the slide plate 130. Further, the positional relationship between the magnets 161a and 162a (161b and 162b) and the first and second coils 1611 and 1622 with respect to the movable yoke 140 and the fixed yoke may be interchanged.

Moreover, although it shall be used for the steering 26 of a vehicle in said each embodiment, it is applicable also to an aircraft etc. besides which the up-and-down relationship changes.

Further, the display system 10 of each of the above embodiments may be provided with a head-up display device instead of the navigation device 20 or together with the navigation device 20. The head-up display device is accommodated in the instrument panel of the vehicle in front of the driver's seat, and displays a virtual image of the image by projecting the image toward a projection area defined in the window shield. The operator seated at the driver's seat can visually recognize, through the projection area, a plurality of icons associated with a predetermined function, a pointer for selecting an arbitrary icon, and the like. The pointer can be moved in the projection area in the direction corresponding to the input direction of the operating force by the operation input to the operation knob 120 as in the case of being displayed on the display screen 22.
