  The present invention relates to a dial type operating device.

JP-A-10-199374 JP 2005-317376 A

  In a vehicle such as an automobile, an electronic device to be mounted, for example, an air conditioner, a car audio system, and an operation unit for operating a car navigation system are provided, for example, in a vehicle instrument panel portion. The operation unit is provided with an operation unit for a vehicle occupant to operate as necessary. Of these, dial type operation devices are often used for air volume adjustment operation units, temperature adjustment operation units or outlet selection operation units of air conditioners, and volume operation units of car audio systems. In recent years, the dial type operation device has been remarkably multi-functional, and in addition to the rotation operation around the axis of the dial knob, the push operation function in the axial direction and the swing operation in the direction inclined from the axis ( A device incorporating a tilt operation function has also been put into practical use (Patent Documents 1 and 2).

  However, in the dial type operation device of Patent Document 1, the rotation operation function and the swing operation are allocated separately to the rotor (dial knob) and the swing operation stem disposed inside thereof. The dial knob itself does not accept swinging operation. In this case, the rocking direction is selected by changing the pressing position on the front end surface of the stem exposed inside the dial knob, but the side surface of the stem cannot be used as the operation surface, so there is a drawback that erroneous operation is likely to occur. is there. In addition, when shifting from the rotation operation to the swing operation, it is necessary to change the handle for pressing the stem on the front side from the state where the knob is gripped, and there is a problem that the operability is poor.

  Patent Document 2 has been proposed to solve this problem, and the dial knob itself has a structure in which a degree of freedom of operation in the swing direction is given. On the other hand, rotation detection is performed in a non-swinging manner separate from the dial knob. This is done by a rotary encoder integrated with the dynamic rotary connecting part. The operation rotational displacement of the dial knob is transmitted to the rotational connection component by the interlocking spring, and this interlocking spring functions as a universal joint that transmits the rotation while absorbing the swinging displacement of the dial knob.

  However, in the configuration of Patent Document 2, the universal joint portion must be configured with a separate interlocking spring, which has the disadvantage of increasing the number of components. In addition, since the interlocking spring has flexibility in the torsional direction, when the dial knob is rotated, the torsional displacement of the interlocking spring may cause a transmission delay to the rotary connecting component. Further, since the interlocking spring has continuous swing flexibility around the operation axis, there is a problem that it is difficult to regulate the swing operation direction.

  An object of the present invention is to provide a dial type operation device that can add a swing operation function to a dial knob without increasing the number of parts.

Means for Solving the Problems and Effects of the Invention

In order to achieve the above object, the dial type operating device of the present invention comprises:
A base rotating body that is mounted on a mounting surface that forms an operation front side of the apparatus base body so as to be rotatable around a fixed axis that intersects the mounting surface;
In the fixed axis direction, it is provided on the operation front side of the base rotating body so that the operating axis coincides with the fixed axis of the base rotating body at the neutral position. The rotating operation around the operating axis and the operating axis coincide with the fixed axis. A dial operation unit capable of swinging between the neutral position and the inclined position where the operation axis is inclined with respect to the fixed axis;
The dial operation unit allows the base rotary body to rotate with the dial operation unit in accordance with the rotation operation while allowing a relative tilt displacement of the operation axis of the dial operation unit with respect to the fixed axis of the base rotary body with the swing operation. And the base rotating body, and a base side engaging portion formed at a plurality of predetermined positions in the rotational circumferential direction of the base rotating body, and each base side engaging portion in the rotational circumferential direction of the dial operating portion And an operation portion side engagement portion that engages with a corresponding base side engagement portion, and one of the base side engagement portion and the operation portion side engagement portion is guided. The other is a guide portion that guides the relative movement of the guided body in the fixed axis direction derived from the swinging operation while restricting the relative movement derived from the rotation operation of the guided body. Tilting allowable rotary coupler And,
A rotation operation position detection unit that detects a rotation angle position of the base rotation body as a rotation operation position of the dial operation unit;
A swing operation detecting unit for detecting a swing operation of the dial operation unit;
Equipped with a,
The guided body is a protrusion that protrudes in the radial direction with respect to the fixed axis, and the guide part is a guide recess that receives the protrusion and extends along the fixed axis.
When the guide recess is located at an angular position deviating from an integral multiple of 90 ° with respect to the swinging operation direction around the fixed axis, the protrusion moves along a trajectory inclined with respect to the fixed axis within the guide recess. The clearance for accepting this is formed between the inner surface of the guide recess and the protrusion in the circumferential direction of the base rotating body .

  According to the configuration of the dial type operating device of the present invention, the rotational operation displacement of the swingable dial operating unit is transmitted to the base rotating body via the tilt allowable rotation coupling mechanism, and the rotational angle position of the base rotating body is dialed. It is detected as the rotation operation position of the operation unit. The base rotating body rotates around a fixed axis intersecting the mount surface and is not rocked. Therefore, the rotation can be reliably detected without being affected by the swinging operation of the dial operation unit. Then, base side engaging portions are formed at a plurality of predetermined positions in the rotational circumferential direction of the base rotating body, and an operation portion side engaging portion that engages with the base side engaging portion is provided on the dial operating portion. One of the base side engaging portion and the operating portion side engaging portion is a guided body, and the other is guided by the swing operation while restricting relative movement derived from the rotation operation of the guided body. The tilt allowable rotation coupling mechanism is configured in the form of a guide portion that guides relative movement of the body in the fixed axis direction. That is, since a structure in which the dial operating portion and the base rotating body are directly engaged by the guided body and the guide portion is adopted, a separate part such as the interlocking spring of Patent Document 2 is not required, and the dial knob is swung. Operation functions can be easily added. Further, since the rotation is transmitted by direct engagement between the dial operating portion and the base rotating body, it is possible to eliminate a transmission delay element derived from the intervention of an intermediate part such as an interlocking spring. One of the base side engaging portion and the operating portion side engaging portion is a guided body, and the other is a relative movement of the guided body in the fixed axis direction (of the base rotating body) derived from the swinging operation. As a guide part for guiding the movement, there is also an advantage that the swinging operation direction can be appropriately regulated.

  The guided body may be a protrusion that protrudes in the radial direction with respect to the fixed axis (of the base rotating body), and the guide part may be a guide recess that receives the protrusion and extends along the fixed axis. it can. The guide recess can be formed as a bottomed groove or a through slit (hereinafter, in the present invention, both the bottomed groove and the through slit are regarded as belonging to the concept of “groove” in a broad sense). The protrusion in the guide recess can effectively regulate the relative movement of the protrusion by the inner surface in the width direction of the guide recess during rotation operation, and the protrusion can be freely advanced and retracted in the depth direction of the protrusion during swinging operation. In this state, the movement in the longitudinal direction can be guided by the inner surface in the width direction of the guide recess.

  The allowable direction of the swing operation of the dial operation unit on the mount surface of the apparatus base can be fixed in advance, for example, around the fixed axis (of the base rotating body). In this case, although the swing operation allowable direction is fixed, the tilt allowable rotation coupling mechanism including the protrusion and the guide recess provided in the dial operation unit and the base rotating body rotates around the fixed axis by the rotation operation. Therefore, the movement trajectory of the protrusion in the guide recess changes according to the angular phase difference between the fixed swinging operation allowable direction and the moving tilt allowable rotation coupling mechanism. Specifically, when the angular phase difference between the swing operation allowable direction and the tilt allowable rotation coupling mechanism is 0 ° (that is, phase matching) or 180 ° (that is, phase inversion), the protruding portion within the guide recess Is relatively displaced along a trajectory coinciding with the longitudinal direction of the guide recess, and no displacement component is generated in the width direction of the guide recess (that is, the circumferential direction of the base rotating body). On the other hand, when the angle phase difference between the swing operation allowable direction and the tilt allowable rotation coupling mechanism is 90 ° (value seen on the small angle side), the protrusion is within the guide recess and around the axis perpendicular to the fixed axis. It only rotates relatively, and displacement in the longitudinal direction and the width direction of the guide recess does not occur.

  Accordingly, when the angular phase difference between the swing operation allowable direction and the tilt allowable rotation coupling mechanism is at least one of four positions of 0 °, 90 °, 180 °, and 270 ° (that is, the dial operation unit is swingable). When the device is configured so that the swing operation can be performed only when it is in the rotational operation position where the above-described angular phase difference is seen from the operation allowable direction), the clearance in the recess width direction between the guide recess and the protrusion It is also possible to make the gap fit in the width direction as small as possible. By doing so, it is possible to reduce the backlash of the dial operation unit in the direction of the rotation operation with respect to the base rotating body.

  However, when the dial operation portion is allowed to swing even at a rotational operation position where the angular phase difference is other than the above, that is, the guide recess around the fixed axis is from an integral multiple of 90 ° with respect to the swing operation direction. If the angular position is allowed to deviate, the projecting portion moves along a trajectory inclined with respect to the longitudinal direction of the concave portion in the guide concave portion, and generates a displacement component in the width direction of the guide concave portion. . This width direction displacement component becomes maximum when the angular phase difference between the swing operation allowable direction and the tilt allowable rotation coupling mechanism is 45 ° (value seen on the small angle side). In this case, a clearance for allowing the protrusion to move along a locus inclined with respect to the fixed axis in the guide recess is provided between the inner surface of the guide recess and the protrusion in the circumferential direction of the base rotating body. It is necessary to form. In other words, by forming this clearance, the swing operation to the dial operation unit can be performed without any problem regardless of the angular position of the tilt-allowable rotation coupling mechanism with respect to the swing operation allowable direction. .

  The guide recess can be a groove having the fixed axis direction as the groove longitudinal direction. In this case, the inner side surface in the width direction of the groove is preferably formed so that the groove width is narrower than the both end sections in the central section in the fixed axis direction. When the operation axis of the dial operation portion is at a neutral position related to the swing operation, the protruding portion faces the central section on the inner side surface in the width direction in the groove portion. Therefore, by reducing the groove width in the central section, the clearance between the groove and the projecting portion is reduced, and it is possible to suppress rattling when the dial operation unit is rotated at the neutral position. it can. On the other hand, when the groove width is expanded at both end sections of the groove, the swinging operation direction is at an angular phase deviating from an integral multiple of 90 ° with respect to the position of the tilting allowable rotation coupling mechanism (groove). Can sufficiently secure a clearance that allows the protruding portion to move obliquely with the swing operation of the dial operation portion. Specifically, the inner side surface of the groove portion in the width direction can be configured such that the central section bulges inward in the groove width direction.

  Further, depending on the angle phase with respect to the swinging operation direction of the tilt-allowing rotation coupling mechanism, the projecting part may rotate relatively within the groove part. In this case, even when the clearance with the groove portion becomes small as in the above-described central section, the protruding portion may be formed to have a circular contour shape so that the rotation of the protruding portion is allowed smoothly. desirable.

  The base rotator can be stably supported on the apparatus base by being rotatably fitted to the outside of the base cylindrical portion protruding from the mounting surface of the apparatus base. In this case, the operation portion side engagement portion can be formed at the rear end of the dial operation portion in the fixed axis direction, and the base side engagement portion can be formed on the outer peripheral surface of the base rotating body.

  The device base of the operating device is accommodated in the device housing. In this case, the dial operation unit includes a dial knob disposed so as to protrude from the front surface of the housing in a knob mounting hole formed in the front surface of the device housing, and a rear end of the dial knob. A cylindrical fitting portion that fits into the opening in a non-rotatable manner, and a rotation transmission member that has a coupling main body united in a form that is larger in diameter than the dial knob on the rear end side of the cylindrical fitting portion Can be configured as By providing such a rotation transmission member, the base rotating body can be formed larger in diameter than the dial knob, the internal space of the base rotating body can be expanded, and the rotation radius of the base rotating body involved in the rotation operation position detection is increased. Therefore, the resolution of rotation angle detection can be increased. In this case, a protruding portion is formed on one of the inner peripheral surface of the rear end portion of the coupling main body portion of the rotation transmitting member and the outer peripheral surface of the base rotating body formed larger in diameter than the dial knob, and a guide concave portion is formed on the other. be able to.

  The swing operation detection unit is a swing detection push switch mounted in a region exposed on the inner side of the base cylindrical portion of the substrate that is fitted to the back side of the apparatus base, corresponding to the swing operation direction. be able to. On the inner surface of the base cylindrical portion, on the mounting surface of the device base, the rotation around the fixed axis is impossible, and the dial operation portion is supported to be rotatable from the inside, and the dial operation portion is swung. Accordingly, a swing detection switch biasing body that swings and displaces integrally with the dial operation unit and biases the swing detection pressing switch corresponding to the swing direction may be provided. it can. By enlarging the internal space of the base rotating body, the arrangement space for the rocking detection push switch (or a plurality of rotating switches when multiple swinging operation directions are set) is supported (the base rotating body is rotatably supported). Yes) It can be secured with a margin on the inside of the base cylindrical portion.

  The swing detection switch urging body includes a holder side cylindrical portion that rotatably supports the cylindrical fitting portion of the rotation transmitting member from the inside, and a holder main body integrated with the rear end of the holder side cylindrical portion. And a first holder having a first swinging coupling in a first swinging direction via a first swinging coupling portion, and from the mounting surface of the apparatus base on the inner side of the base cylindrical portion. A second holder that is coupled to the projecting holder-engagement cylindrical portion so as to be capable of swinging via a second swing coupling portion in a second swing direction orthogonal to the first swing direction. Can be configured as In this way, the structure in which two holders each having a unique swinging direction are connected by the two-stage swing coupling portion allows the direction of the swing operation applied to the dial operation portion to be changed here. It is possible to properly correct in the swing allowable direction defined by the coupling portion. In this case, the dial operation unit transmits the swing displacement force of the second holder as a pressing biasing force to the swing detection press switch via a pusher disposed between the swing detection press switch. In addition, even if a swing operation in a direction slightly deviated from the swing allowable direction is applied, the corresponding swing detection pressing switch can be reliably biased.

  Next, the rotational operation position detection unit includes a detected body row formed in the circumferential direction at the axial rear end of the base rotating body, and a rotational movement detection unit that detects the rotational movement of the detected body row. It can be configured as having. By forming the detected body row at the rear end of the base rotating body in the axial direction far from the dial operation section, a space for arranging the rotational movement detecting section can be ensured. The detected object row is a concavo-convex pattern formed on the rear end surface of the cylindrical base rotator so that the fixed axis direction is the amplitude direction, and the rotational movement detection unit is directed toward the concavo-convex pattern. A non-contact detection unit that outputs a detection probe in the rotational radius direction can be used. The detection probe can employ light (including infrared rays) and ultrasonic waves. As a simple configuration, a photo interrupter in which a light emitting diode and a phototransistor are combined can be exemplified.

  On the other hand, the detected object row is attached to the rear end surface of the cylindrical base rotating body, and a magnetic object in which first and second detected parts that are magnetically non-equivalent in the circumferential direction are alternately formed. It can be a detector ring. The rotational movement detection unit can be a magnetic detection unit that detects a magnetic field variation accompanying the rotation of the magnetic detection object ring. Even with this configuration, the rotation of the base rotating body can be detected in a non-contact manner, and is not easily affected by dirt on the rotational movement detector.

Occasionally, the phototransistor receives light, and the phototransistor becomes light-shielded when passing through the convex portion, whereby the output terminal voltage of the phototransistor changes, and based on this, the rotation angle can be pulse-detected. In addition, as shown in FIG. 1, on the mount surface MP of the apparatus base 10 at a position corresponding to the rear end portion of the outer peripheral surface of the base rotator 8, a click that gives a sense of moderation to the rotation of the base rotator 8 A mechanism 9 is provided.

  As shown in FIG. 8, the detected object row 82 is attached to the rear end surface of the cylindrical base rotating body 8, and the first detected part MG1 and the second detected object that are magnetically non-equivalent in the circumferential direction. It can also be set as the magnetic sensing object ring 82m by which the part MG2 was formed alternately. The rotational movement detection unit 12 is a magnetic detection unit 82s that detects a magnetic field variation accompanying the rotation of the magnetic detection object ring 82m. The magnetic detection object ring 82m can be configured, for example, as a permanent magnet ring (so-called pulsar ring) in which magnetized regions having different polarities are alternately arranged in the circumferential direction, and the magnetic detection unit 82s is configured by a magnetic head, a Hall element, or the like. it can.

  The usage method of the dial type operating device 200 of the present invention is as follows. That is, if the dial knob 1 is gripped and rotated by hand, the base rotating portion 8 rotates in a manner that rotates with the dial knob 1, and its angular displacement is detected by the rotational operation position detecting portion 12, so that the angular position can be input. It becomes. On the other hand, when a swing operation is applied to the dial knob 1 in any of the four directions (12 o'clock, 3 o'clock, 6 o'clock, 9 o'clock) in FIG. The swinging operation force is transmitted to the force member 70, the swing detection switch biasing member 70 is tilted, and the corresponding swing detection pressing switch 14 is biased, so that an electrical input corresponding to the swing direction is received. Made. FIG. 5 shows a case where a swing operation in the 6 o'clock direction is applied to the dial knob 1, and FIG. 6 shows a case where a swing operation in the 3 o'clock direction is applied to the dial knob 1.

  The rotational operation displacement of the swingable dial knob 1 is transmitted to the base rotating body 8 via the tilt allowable rotation coupling mechanism 151, and the rotational angle position of the base rotating body 8 is detected as the rotational operation position of the dial knob 1. . Since the base rotating body 8 rotates around the fixed axis O intersecting with the mount surface MP and is not rocked, the rotation can be reliably detected without being affected by the rocking operation of the dial knob 1. it can.

  On the other hand, base-side engaging portions 81 (guide concave portions 81) are formed at a plurality of predetermined positions in the rotational circumferential direction of the base rotating body 8, and the rotation transmitting member 4 is engaged with the base-side engaging portion 81. The part side engaging part 41 (projection part 41) is formed. Since the rotation transmitting member 4 and the base rotating body 8 which form a part of the dial operation portion are directly engaged by the guided body 41 and the guide portion 81, separate parts such as the interlocking spring of Patent Document 2 are not required. In addition, a swing operation function can be easily added to the dial operation unit. Further, since the rotation is transmitted by direct engagement between the rotation transmitting member 4 and the base rotating body 8, a transmission delay element derived from the intervention of an intermediate part such as an interlocking spring can be eliminated. In the tilt-allowed rotation coupling mechanism 151, the protrusion 41 in the guide recess 81g is moved relative to the protrusion 41 by the inner surface in the width direction of the guide recess 81g during rotation, and as a result, the rotation transmitting member 4 is moved relative to the base rotating body 8. Relative rotation can be effectively controlled. Further, at the time of swinging operation, the protrusion 41 is moved freely in the longitudinal direction of the recess 41 by the inner surface in the width direction of the guide recess 81g, and the rotation is transmitted while the protrusion 41 is freely allowed to advance and retract in the depth direction of the recess. The displacement of the member 4 along the fixed axis O with respect to the base rotating body 8 can be guided.

  By the way, in this embodiment, the rocking | fluctuation operation permissible direction of the dial knob 1 is being fixed to four directions of FIG. The tilt allowable rotation coupling mechanism 151 composed of the protrusion 41 and the guide recess 81g rotates around the fixed axis O by a rotation operation. Therefore, the movement trajectory of the protrusion 41 in the guide recess 81g changes according to the angular phase difference between the fixed swing operation allowable direction and the tilt allowable rotation coupling mechanism 151 that moves. Specifically, when the angular phase difference between the swing operation allowable direction and the tilt allowable rotation coupling mechanism 151 is 0 ° (that is, phase matching) or 180 ° (that is, phase inversion), as shown in FIG. Within the guide recess 81g, the protrusion 41 is relatively displaced along a locus V that coincides with the longitudinal direction of the guide recess 81g, and extends in the width direction of the guide recess 81g (that is, the circumferential direction of the base rotating body 8). There is no displacement component. On the other hand, when the angular phase difference between the swing operation allowable direction and the tilt allowable rotation coupling mechanism 151 is 90 ° (value viewed from the small angle side), the protrusion 41 is orthogonal to the fixed axis O in the guide recess 81g. The rotation of the guide recess 81g does not occur in the longitudinal direction and the width direction.

  However, when the tilt allowable rotation coupling mechanism 151 has an operation angle phase that does not coincide with any of the four directions in FIG. 1, the protrusion 41 in FIG. 7 has a recess longitudinal direction (V) in the guide recess 81g. And a displacement component H in the width direction of the guide recess 81g is generated. This width direction displacement component H has an angular phase difference of 45 ° between the swing operation allowable direction and the tilt allowable rotation coupling mechanism 151 (that is, the tilt allowable rotation coupling mechanism 151 is 1:30, 4:30 in FIG. At 7:30 and 10:30).

  In the present embodiment, as shown in FIG. 7, the clearance C for allowing the protrusion 41 to move along the trajectory inclined with respect to the fixed axis O in the guide recess 81 g is provided on the base rotating body 8. It is formed between the inner surface of the guide recess 81g and the protrusion 41 in the circumferential direction. By forming the clearance C, the swing operation to the dial operation units 1 and 4 can be performed without any problem, regardless of the angular position of the tilt allowable rotation coupling mechanism 151 with respect to the swing operation allowable direction. be able to.

  As described above, the guide recessed portion 81g is a groove portion 81g having the fixed axis O direction as the groove longitudinal direction. Specifically, the guide recess 81g has a narrower width than the both end sections 81t in the central section 81m in the fixed axis O direction. The inner side shape of the width direction is determined so as to bulge inward in the groove width direction in the central section 81m. As shown in FIGS. 1 to 3, when the operation axis K of the dial knob 1 is in the neutral position, the protrusion 41 in FIG. 7 faces the central section 81m of the groove 81g. Therefore, by reducing the groove width in the central section, the clearance C between the groove portion 81g and the protruding portion 41 is reduced, and the dial operation portions 1 and 4 are rotated at the neutral position. Suppression can be suppressed. On the other hand, by expanding the groove width at both end sections of the groove portion 81g, the dial knob 1 can be used even when the swing operation allowable direction and the tilt allowable rotation coupling mechanism 151 are in an angular phase relationship that does not coincide with each other. A clearance C that allows the protrusion 41 to move obliquely with the swing operation can be sufficiently secured in the guide recess 81g.

  Further, depending on the angle phase with respect to the swinging operation direction of the tilting allowable rotation coupling mechanism 151, the projecting portion 41 may rotate relatively in the groove portion 81g. In particular, when the angular phase difference between the swing operation allowable direction and the tilt allowable rotation coupling mechanism 151 is 90 ° (value seen on the small angle side), the protrusion 41 is orthogonal to the fixed axis O in the guide recess 81g. It will only rotate relatively around the axis line. Considering this, as shown in FIG. 7, the protruding portion 41 is formed to have a circular contour shape.
