  However, in the prior art as described above, it is difficult to improve the positional stability during the operation of the operation member. For example, in the above-mentioned prior art, since the magnets face each other in a non-contact manner, the sliding resistance against the movement at the time of operation of the operation member is very small. Therefore, for example, when the operating member is vigorously returned to the operating position where the attraction between the magnets is maximized, the operating member does not settle (rest) immediately at the operating position, and slightly vibrates back and forth There is a high possibility of doing. If the position stability is not good, there is a problem that the operation is oscillatory and the operation feeling is poor.

  Therefore, in one aspect, the present invention aims to enhance the positional stability during operation of the operation member.

In one aspect, an operating member that is tilted and operated;
A support that supports the operation member so as to be tiltable about a tilt center axis in a first direction;
A permanent magnet provided on the operation member and having different magnetic poles adjacent to each other in the first direction;
A yoke having a convex portion surrounding a movement locus of the permanent magnet along with the movement of the operation member at the time of tilting operation, and projecting in a direction approaching the movement locus in the first direction;
A sliding member provided between the permanent magnet or the operating member and the yoke;
An operating device is provided in which the permanent magnet or the operating member and the sliding member abut in the first direction by a suction force between the permanent magnet and the yoke.

  In one aspect, according to the present invention, it is possible to improve the positional stability during the operation of the operation member.

  Hereinafter, each example will be described in detail with reference to the attached drawings.

  FIG. 1 is an external perspective view of a shift device 100 (an example of an operating device) according to an embodiment. Three orthogonal axes X, Y, Z are defined in FIG. In the Z direction, the positive side corresponds to the "upper side". FIG. 2 is a perspective view of the single-piece state of the support 110 of the shift device 100, and FIG. 3 is a perspective view of the yoke 60. FIG. 4 is a perspective view showing the relationship between the yoke 60 and the control lever 2. In FIG. 4, illustration of a part of the control lever 2 (shift knob 2 a) is omitted. FIG. 5 is a cross-sectional view of the shift device 100 when it is cut along the XY plane passing through the permanent magnet 50. As shown in FIG. In FIG. 5, the polarities "S" and "N" of the permanent magnet 50 are shown, and the center lines C1 and C2 in the X and Y directions of the yoke 60 are shown.

  The shift device 100 is preferably provided in a vehicle. However, the shift device 100 may be provided in an aircraft, a railway, or the like, or may be applied to a game machine.

  The shift device 100 is not a mechanical control system in which the control lever 2 is directly connected to the transmission, but a shift-by-wire system. Since the shift device 100 of the shift by wire method does not require a mechanical configuration such as a link mechanism, downsizing can be achieved. Therefore, the layout of the shift device 100 in the vehicle can be made flexible. In addition, since the operation lever 2 can be operated with a relatively small force, the operation of the shift change becomes easy.

  The shift device 100 includes an operation lever 2 capable of tilting operation, and a support 110 that tiltably supports the operation lever 2.

  A shift knob 2 a is attached to the upper end of the operation lever 2. The shift knob 2a is an operation unit held by the user. A tilt shaft 16 is integrally attached to the control lever 2. Both ends of the tilting shaft 16 are rotatably supported by bearings 110 a on the support 110 side. Thus, the operation lever 2 is supported on the support 110 so as to be able to tilt in the first tilting direction (D1 direction) or the second tilting direction (D2 direction). However, in the modification, the operation lever 2 may be rotatably supported by the tilting shaft 16. In this case, the tilting shaft 16 is fixed to the support 110 side.

  The support 110 supports the operation lever 2 (an example of the operation member) so as to be capable of tilting around the tilt central axis in the X direction (an example of the first direction). The tilting central axis is defined by the tilting axis 16.

  The support 110 includes a frame 112 and an attachment portion 114 for the tilting shaft 16. In the modification, the frame 112 and the attachment portion 114 may be formed by separate members.

  The frame 112 is in the form of a rectangular frame, and the lower end 22 of the control lever 2 is disposed in a space 112 a in the frame. The frame body 112 is provided between the lower end 22 of the control lever 2 and the yoke 60. The surface of the frame 112 on the space 112 a side is planar. On the other hand, the surface of the frame body 112 on the opposite side to the space 112 a side has a concavo-convex shape corresponding to the convex portion 62 described later. The frame body 112 forms an example of a sliding member which abuts on the control lever 2 in the X direction by the suction force between the permanent magnet 50 and the yoke 60 as described later. The frame body 112 is joined to the yoke 60 in a manner to be surrounded by the yoke 60 described later.

  The frame 112 has a first portion 112-1 on the negative side in the X direction (an example on the first side) and a second portion 112-2 on the positive side in the X direction (an example on the opposite side to the first side). including. Further, the frame 112 further includes a third portion 112-3 on the positive side in the Y direction and a fourth portion 112-4 on the negative side in the Y direction. The first portion 112-1 to the fourth portion 112-4 are in the form of a rectangular frame by being continuous.

  The distance d1 between the first portion 112-1 and the second portion 112-2 in the X direction is larger than the width d2 of the lower end 22 of the control lever 2 in the X direction, as shown in FIG. Therefore, the operation lever 2 is a difference distance Δ1 (= d2−d1) (hereinafter referred to as “first distance Δ1”) of the difference between the distance d1 and the width d2 in the X direction with respect to the frame 112 (and accordingly the yoke 60). It can be displaced. Thereby, the lower end 22 of the operation lever 2 can contact only one of the first portion 112-1 and the second portion 112-2.

  Here, when the lower end 22 of the operation lever 2 abuts on both the first portion 112-1 and the second portion 112-2 in the X direction, the sliding resistance may be excessive. In this respect, by providing the first distance Δ1 larger than 0 as a design value, the lower end 22 of the operation lever 2 can abut on only one of the first portion 112-1 and the second portion 112-2 in the X direction. Therefore, the disadvantage that the sliding resistance becomes excessive can be prevented. The first distance Δ1 is set, for example, in such a manner as to absorb manufacturing tolerances, assembly tolerances, and the like of related parts. This makes it possible to prevent the problem that the sliding resistance becomes excessive even when manufacturing tolerances of parts occur.

  The mounting portions 114 are provided on both sides of the frame 112 in the X direction, and form a pair. As described above, the tilt shaft 16 in the X direction is rotatably supported by the mounting portion 114.

  Shift device 100 further includes a permanent magnet 50 and a yoke 60.

  The permanent magnet 50 is provided on the control lever 2. In the present embodiment, as an example, the permanent magnet 50 is provided at the lower end 22 of the control lever 2. That is, as shown in FIG. 5, the permanent magnet 50 is fitted in the hollow portion of the lower end 22 of the control lever 2. The connection method between the permanent magnet 50 and the control lever 2 is optional. For example, the permanent magnet 50 and the control lever 2 may be integrated by bonding, press-fitting, integral molding, or the like.

  The permanent magnet 50 is provided at the lower end 22 of the control lever 2 and moves along with the movement of the control lever 2 at the time of tilting operation. Hereinafter, the movement locus of the permanent magnet 50 along with the movement of the control lever 2 at the time of the tilting operation is also simply referred to as "movement locus of the permanent magnet 50" or "movement locus". The movement locus of the permanent magnet 50 is in the form of an arc around the tilt axis 16 when viewed in the X direction. Further, the movement locus of the permanent magnet 50 is parallel to the Y direction as viewed in the Z direction. Further, the movement locus of the permanent magnet 50 passes near the center of the yoke 60 in the X direction as viewed in the Z direction.

  The permanent magnet 50 has different magnetic poles adjacent in the X direction. In FIG. 5, in the permanent magnet 50, the S pole and the N pole are separated at the center position in the X direction, and the N pole is located on the negative side in the X direction. In the modification, the N pole may be located on the positive side in the X direction.

  The yoke 60 extends in such a manner as to surround the movement trajectory of the permanent magnet 50. In other words, the yoke 60 has a rectangular frame shape, and the movement trajectory of the permanent magnet 50 is defined in the space 61 in the frame.

  The yoke 60 is formed of, for example, a soft magnetic material such as iron. The yoke 60 may be integrally formed with the frame 112. For example, the yoke 60 may be integrally formed with the support 110 by insert molding of resin. When the frame 112 and the attachment portion 114 are formed by separate members as described above, the yoke 60 may be integrally formed with the frame 112 by insert molding of resin. In the case of insert molding, it is possible to manufacture a part (an integral part of the yoke 60 and the frame 112) with high accuracy, and since the number of parts is not increased, the assembling property is improved. In a modification, the yoke 60 may be integrated with the separately formed frame 112 by adhesion or the like.

  The yoke 60 has a convex portion 62 projecting in a direction approaching the movement trajectory of the permanent magnet 50 in the X direction. That is, the yoke 60 has a convex portion 62 projecting toward the center of the yoke 60 in the X direction when viewed in the Z direction.

  The yoke 60 having the convex portion 62 can cooperate with the permanent magnet 50 to create a click feeling (see FIGS. 6A and 6B). That is, the attraction force between the permanent magnet 50 and the yoke 60 differs between the position where the permanent magnet 50 faces the convex portion 62 in the X direction and the position where the permanent magnet 50 does not face the convex portion 62 in the X direction. Such a change in suction force can create a click feeling.

  The convex portions 62 are preferably provided in a pair in such a manner as to face each other in the X direction. In this case, as compared with the case where the convex portion 62 is provided only on one side, the change in the attraction force along the movement trajectory of the permanent magnet 50 can be increased (see FIG. 6B).

  In the present embodiment, as an example, three pairs of convex portions 62 are provided. That is, as shown in FIG. 3, the yoke 60 has a first pair 62-1 near the center in the Y direction and second and third pairs 62-2 and 62-3 on both sides in the Y direction. In addition, the convex part 62 which concerns on the 2nd and 3rd pair 62-2 and 62-3 is formed in the aspect which follows the edge part of the Y direction of the yoke 60, as shown to FIG. 3 etc. FIG. When the convex portions 62 are provided in a plurality of pairs, a click feeling can be created at a plurality of positions along the movement trajectory of the permanent magnet 50 (see FIGS. 6A and 6B).

  Hereinafter, the operation position of the operation lever 2 when the permanent magnet 50 faces the convex portion 62 related to the first pair 62-1 in the X direction is referred to as a "first operation position", and the permanent magnet 50 The operation position of the operation lever 2 when facing the convex portion 62 according to the pair 62-2 in the X direction is referred to as “second operation position”, and the permanent magnet 50 is a convex portion according to the third pair 62-3. The operating position of the operating lever 2 when facing 62 in the X direction is referred to as “third operating position”.

  Next, with reference to FIGS. 6A and 6B, the principle of suction force generation (click feeling creation) according to the present embodiment will be described.

  FIG. 6A is an explanatory view of the principle of suction force generation (click feeling creation) according to the present embodiment, and is a plan view showing the relationship between the yoke 60 and the permanent magnet 50. FIG. In FIG. 6A, the flow of magnetic flux is schematically shown by arrow R1. In FIG. 6A, the flow of magnetic flux at the first operating position is shown. FIG. 6B is a diagram showing the characteristics of the present embodiment, with each operation position of the control lever 2 as the horizontal axis and the magnetic force in the Y direction acting on the control lever 2 as the vertical axis. In FIG. 6B, the magnetic force is "positive" in the suction direction (the negative direction of the Y axis). In FIG. 6B, the first operation position, the second operation position, and the third operation position are indicated by P11, P12, and P13, respectively. P <b> 14 and P <b> 15 correspond to the operation position of the operation lever 2 when the permanent magnet 50 faces the concave portion 63 between the convex portions 62 in the X direction.

  In the first operating position, as shown by arrow R1 in FIG. 6A, a flow of magnetic flux is generated, and as shown in FIG. 6A, a suction force is generated between the yoke 60 and the permanent magnet 50. The attraction between the yoke 60 and the permanent magnet 50 changes along the movement trajectory of the permanent magnet 50 due to the convex portion 62 in the yoke 60. Thereby, as shown in FIG. 6B, the magnetic force in the Y direction acting on the operation lever 2 changes at each operation position of the operation lever 2, so that the click feeling transmitted to the user when the operation lever 2 is tilted is operated. Is created.

  Next, with reference to FIG. 7A and FIG. 7B, the principle of the effect (the effect of enhancing the positional stability) according to the present embodiment will be described.

  FIGS. 7A and 7B are explanatory views of the principle of the effect (the effect of enhancing the positional stability) according to this embodiment, and are plan views showing the relationship between the yoke 60 and the permanent magnet 50. FIG. In FIG. 7A and FIG. 7B, the attraction | suction force (reaction force) of the X direction which acts on the permanent magnet 50 is shown by F1, F2. 7A and 7B show the state of the suction force at the first operation position.

  Here, when the center P1 between the same pair of convex portions 62 in the X direction coincides with the center P2 of the permanent magnet 50 in the X direction, as shown in FIG. 7A, the X direction acting on the permanent magnet 50 The suction forces F1 and F2 become the same and are offset. On the other hand, when the center P1 between the same pair of convex portions 62 in the X direction and the center P2 of the permanent magnet 50 do not coincide in the X direction, the attractive force of the closer one of the pair of convex portions 62 Becomes stronger. That is, in the example shown in FIG. 7B, the suction force F1 is larger than the suction force F2. Thus, the permanent magnet 50 can be attracted to the closer one of the pair of projections 62 at the first operation position. As a result, the lower end 22 of the control lever 2 can contact the frame 112 in the X direction at the first operation position (see FIG. 5). When the lower end 22 of the control lever 2 abuts on the frame body 112 in the X direction, sliding resistance occurs with respect to the movement along the movement trajectory, so that the position stability at the first operation position can be improved.

  Although the positional stability at the first operating position has been described here, the positional stability at the operating position of the operation lever 2 when the permanent magnet 50 faces the recess 63 between the convex portions 62 in the X direction Can be enhanced as well.

  The sliding surface on the frame 112 side (the surface on the space 112 a side of the first portion 112-1) preferably has sliding characteristics (static friction coefficient or dynamic friction coefficient) such that appropriate sliding resistance is generated. For example, the frame 112 may be formed of a synthetic resin such as an acetal resin or a polyacetal resin.

  As described above, according to the present embodiment, it is easy to achieve miniaturization and improvement in durability by creating a click feeling by magnetic force, as compared with a configuration using a cam mechanism to create a click feeling. . Further, according to the present embodiment, it is desired that the lower end 22 of the control lever 2 is made to slide by coming into contact with the frame 112 at the time of the tilting operation of the control lever 2 while creating a click feeling by the magnetic force. It is possible to improve the positional stability at the operation position.

  Next, referring to FIG. 5 again, a further preferable configuration in the present embodiment will be described.

  In a state where the lower end 22 of the control lever 2 abuts on the first portion 112-1 in the X direction, the center P1 between the same pair of convex portions 62 in the X direction and the center P2 of the permanent magnet 50 in the X direction The distance Δ2 between is preferably greater than the first distance Δ1. In this case, even if the lower end 22 of the operation lever 2 abuts on the second portion 112-2 in the X direction, the center P2 of the permanent magnet 50 in the X direction is the first one than the center P1 between the pair of convex portions 62. 1 Offset to the side of 112-1. Therefore, the lower end 22 of the control lever 2 is sucked to the first portion 112-1. As a result, the lower end 22 of the control lever 2 can be stably maintained in contact with the first portion 112-1 in the X direction. The state in which the lower end 22 of the control lever 2 is in contact with the first portion 112-1 and the state in which the lower end 22 of the control lever 2 is in contact with the second portion 112-2 is during tilting operation of the control lever 2. When it changes to, it is possible to give the user a sense of discomfort (a feeling of looseness in the operation feel or a rattling feeling in the X direction). When the state in which the lower end 22 of the control lever 2 abuts on the first portion 112-1 in the X direction can be stably maintained, such discomfort can be reduced. Hereinafter, such a relationship between the distance Δ2 and the first distance Δ1 is also referred to as “bias relationship of magnet attraction force”.

  In the present embodiment, the center P1 between the pair of convex portions 62 in the X direction coincides with the center of the yoke 60 in the X direction. That is, the yoke 60 is symmetrical with respect to the YZ plane passing through the center of the yoke 60 in the X direction.

  Here, as the distance Δ2 becomes larger than the first distance Δ1, the difference in the attraction force in the X direction acting on the permanent magnet 50 becomes larger between the pair of convex portions 62, so the sliding resistance also becomes larger. Therefore, desired sliding characteristics may be realized by appropriately adjusting the difference between the distance Δ2 and the first distance Δ1.

  The first portion 112-1 preferably has a smaller thickness in the X direction than the second portion 112-2 in order to realize the above-described bias relationship of the magnet attraction force. The relationship of thickness is preferably a relationship when compared at each position in the Y direction. Thereby, the bias relationship of the above-mentioned magnet attractive force is realized while configuring the yoke 60 symmetrically with respect to the YZ plane passing through the center of the yoke 60 in the X direction. Therefore, in this case, by adjusting the thickness of the first portion 112-1 and the second portion 112-2, it is possible to realize the above-described bias relationship of the magnet attraction force. In the modification, instead of or in addition to adjusting the thickness of the first portion 112-1 and the second portion 112-2, the thickness of the lower end 22 in the X direction may be a positive side and a negative side in the X direction. The bias relationship of the above-mentioned magnet attraction force may be realized by changing the above.

  As mentioned above, although each Example was explained in full detail, it is not limited to a specific example, A various deformation | transformation and change are possible within the range described in the claim. In addition, it is also possible to combine all or a plurality of the components of the above-described embodiment.

  For example, in the embodiment described above, the lower end 22 of the control lever 2 slides on the frame 112, but the present invention is not limited thereto. For example, the permanent magnet 50 itself may slide on the frame 112. In this case, for example, in a mode in which the permanent magnet 50 forms the lower end of the control lever 2, the permanent magnet 50 may be attached to the control lever 2 in a mode in which the permanent magnet 50 is exposed.

  Further, in the above-described embodiment, the movement locus of the permanent magnet 50 is an arc when viewed in the X direction, but is not limited thereto. For example, the movement trajectory of the permanent magnet 50 may be linear (parallel to the Y direction) as viewed in the X direction by connecting the operation lever 2 and the permanent magnet 50 so as to allow relative displacement.

  In the above-described embodiment, the frame 112 includes the first portion 112-1 to the fourth portion 112-4, but one of the second portion 112-2 to the fourth portion 112-4 or the frame 112 Two or all may be omitted.

  Further, in the above-described embodiment, as a preferable example, the convex portions 62 are provided in a pair facing each other in the X direction, but only one may be provided.

  Further, although three pairs of convex portions 62 are provided in the embodiment described above, the number of pairs is arbitrary.
