Description

  The present invention relates to a rotary switch capable of giving a click feeling to an operator.

  2. Description of the Related Art Conventionally, there has been known a rotary switch including a rotation operation member that is rotated and a click feeling imparting mechanism that gives a click feeling to an operator along with the rotation operation. The click feeling imparting mechanism has, for example, a concavo-convex member that has a concavo-convex pattern in which convex portions and concave portions are alternately arranged in the rotational circumferential direction of the rotational operation member, and rotates integrally with the rotational operation member; It is comprised with the click member which produces a click feeling by engaging intermittently with the recessed part with rotation of this uneven | corrugated member.

  By the way, when a rotary switch having such a click feeling imparting mechanism is mounted on a vehicle, for example, it is desired to change the click feeling according to the type of vehicle mounted, the mode operated by the rotation operation member, and the like. There is a case. If such a click feeling can be changed while using a common rotating operation member, it can greatly contribute to simplification of parts management and cost reduction.

  Conventionally, as shown in FIG. 10, a rotary switch that can change such a click feeling is known (see Patent Document 1). The rotary switch includes a knob unit 100 that is rotated, a moderation mountain member 120 that is coupled to the knob unit 100 via an operation shaft 110 so as to rotate integrally with the knob unit 100, and the moderation mountain member A click member 130 that engages with 120 to generate a click feeling, a motor 140 that drives the click member 130, and an encoder 150 that detects the amount of rotation of the knob unit 100 are provided.

  The moderation peak member 120 has a pattern surface facing the side opposite to the knob portion 100, and the first pattern 121, the second pattern 122, and the third pattern 123 having different uneven pitches on the pattern surface. Is formed. The first pattern 121 is positioned on the rotation center axis of the knob portion 100 together with the operation shaft 110 and the encoder 150, and the second pattern 122 is disposed on the outer side in the radial direction of the first pattern 121. 123 is formed further outside the second pattern 122.

  The click member 130 includes a main body shaft 134 and plunger members 131, 132, and 133 provided on the main body shaft 134 at positions where they can be elastically contacted with the patterns 121, 122, and 123, respectively. Each of the plunger members 131 to 133 protrudes outward in the radial direction from the main body shaft 134 at different angles. The motor 140 causes the plunger member corresponding to the concavo-convex pattern selected from the plunger members 131 to 133 to elastically contact the concavo-convex pattern by rotating the main body shaft 134.

JP 2008-191843 A

  In the rotary switch shown in FIG. 10, there is a problem that the structure is large and the occupied space is large, and further enlargement is necessary to add another function.

  First, regarding the occupied space, in the rotary switch, the main body shaft 134 and the main shaft 134 are rotated in order to selectively make any of the plurality of plunger members 131 to 133 elastically contact with the corresponding concavo-convex pattern. A large case 160 is required to house the motor 140 and hold it in an appropriate position.

  Furthermore, when another function is added, for example, when a composite switch is constructed by combining the rotary switch and a push-type push switch, the dial knob to be rotated is a hollow cylindrical shape if it is a normal rotary switch. In the rotary switch shown in FIG. 10, the operation shaft 110 and the moderation mountain member 120 (of the moderation mountain member 120) can be arranged in the rotary switch shown in FIG. First uneven pattern 121) Furthermore, since the encoder 150 is present, it is extremely difficult to dispose the dial knob in the center of the rotary switch.

  In order to provide a push switch at the center position of the dial knob in such a rotary switch, for example, the knob portion 100 and the moderation mountain member 120 are formed in a hollow cylindrical shape, and the concave and convex patterns 121 to 123 are further formed radially outward. It is conceivable to arrange the encoder 150. However, such an arrangement cannot avoid the increase in the size of the entire rotary switch, in particular, the increase in the size in the rotational radial direction.

  The present invention has been made to solve the above-described problems, and provides a rotary switch that can change the click feeling and can be easily multi-functional without significantly increasing the size of the entire apparatus. The purpose is to provide.

  As means for solving the above-mentioned problems, the present invention is a rotary switch, which is a rotary operation member that is rotated around a specific rotation axis, and holds the rotation operation member rotatably. A holder, a click member that gives a click feeling to the operator in accordance with the rotation operation of the rotation operation member, a rotation detector that detects the rotation operation of the rotation operation member, and the rotation operation member A rotating power transmission member for transmitting the rotating power generated by the rotating operation to the rotation detector. The rotating operation member has a shape that surrounds the space so as to form a predetermined space around the rotating shaft, and rotates around the rotating shaft by the rotating operation. A wall portion projecting over the entire circumference at a predetermined position in the rotation axis direction of the body from the outer peripheral surface of the cylindrical body in the radial direction perpendicular to the rotation axis, and the rotation with respect to the wall portion And a transmission portion that is provided at different positions in the direction of the shaft and transmits the rotational force of the rotation operation member to the rotational power transmission member. The wall portion has a pattern surface facing the back side and having a concavo-convex pattern formed thereon. The pattern surface is disposed around the rotation axis over the entire circumference and has a predetermined number in the circumferential direction. A first concavo-convex pattern having a plurality of first locked recesses arranged intermittently at one interval, and concentrically with the first concavo-convex pattern at a position outside the first concavo-convex pattern in the radial direction. And a second concavo-convex pattern having a plurality of second locked recesses arranged intermittently at a second interval different from the first interval in the circumferential direction. The holder has a first holding portion that holds the click member at a position where the click member can elastically contact the first uneven pattern, and the click member elastically moves the click member to the second uneven pattern. And a second holding portion that holds the touch panel at a position where it can come into contact. The click member can be held by any holding portion of the first holding portion and the second holding portion, and the rotation operation member is rotated in the held state. It has a shape that can give the operator a click feeling by intermittently engaging the first locked recess of the first uneven pattern or the second locked recess of the second uneven pattern. The rotating power transmission member is provided at a position radially outside the outer edge of the cylindrical body and overlapping at least a part of the first uneven pattern and the second uneven pattern in the rotation axis direction. And coupled to the rotation detector and the rotation detector so as to transmit the rotational force of the rotation operation member to the rotation detector.

  The rotary switch of the present invention has a compact structure, and can change the click feeling transmitted to the operator with the turning operation. Specifically, the rotation operation member has a first concavo-convex pattern and a second concavo-convex pattern that rotate around a rotation axis by a rotation operation, and the holder is in elastic contact with the first concavo-convex pattern. Since the first holding portion for holding the click member and the second holding portion for holding the click member so as to elastically contact the second uneven pattern, the uneven pattern for generating a desired click feeling is provided. The click feeling can be easily changed simply by holding the click member in any of the holding portions corresponding to the above. Therefore, a conventional large device such as a motor used for changing the click feeling is not required.

  Furthermore, the rotary switch of the present invention can be easily multi-functionalized by adding a predetermined function in addition to the function of changing the click feeling without significantly increasing the size of the entire apparatus. Specifically, the rotation operation member has a cylindrical body that surrounds the rotation axis so as to form a predetermined space, and the first concavo-convex pattern, the second concavo-convex pattern, and the rotational power transmission member are cylindrical. Therefore, members for other functions such as a pressing operation member and a lighting device constituting a push switch can be incorporated in the space. Moreover, since the rotational power transmission member is disposed at a position overlapping at least a part of the first concavo-convex pattern and the second concavo-convex pattern when viewed from the direction parallel to the rotation axis, the radial dimension of the entire rotary switch It is possible to arrange both the concave and convex patterns and the rotational power transmission member on the outside of the cylindrical body while suppressing the above.

  More specifically, the wall portion is connected to the tube portion at a position where the back side end portion of the tube portion protrudes from the wall portion to the back side, and the transmission portion is configured on the outer peripheral surface of the back side end portion of the tube portion. An external gear is formed, and the rotational power transmission member extends parallel to the rotation shaft and is rotatable about a central axis thereof, and is connected to the transmission shaft and interlocked with the rotation of the rotation operation member. It is preferable to have a transmission gear that meshes with the external gear so as to rotate. Since this rotational power transmission member is arranged in a posture in which the transmission shaft is parallel to the rotational shaft, the rotational power of the rotational operation member is more effectively suppressed while suppressing an increase in the radial dimension of the rotary switch. It is possible to transmit to the rotation detector.

  Furthermore, in this case, the click member includes a displacement member that is displaced so as to be engaged with and disengaged from any of the first locked recess and the second locked recess, and the displacement member. A click spring disposed so as to be elastically pressed against the pattern surface, and the first and second holding portions of the holder extend in a direction parallel to the rotation shaft and open to the pattern surface side. And what makes the container shape which accommodates the said click member so that the spring for a click may expand-contract in the direction parallel to the said rotating shaft is suitable. In this structure, in addition to the transmission shaft of the rotational force transmission member, the first and second holding portions also extend in a direction parallel to the rotation shaft, so that the radial dimension of the rotary switch can be further suppressed. It is.

  The present invention further includes a circuit board on which the rotation detector is mounted, and the holder can be fixed on the circuit board. In this case, the circuit board has a through hole that allows the first and second holding portions extending in the direction parallel to the rotation axis as described above to penetrate in the direction, and thus the dimension is also measured in the direction. It is possible to add a circuit board while suppressing this.

  Further, as a member provided in the predetermined space, a pressing operation member that can be pressed in the rotation axis direction is provided, and a pressing switch that detects the pressing operation of the pressing operation member is mounted on the circuit board. Thus, it is possible to construct a composite switch having both a rotary switch and a push switch while maintaining a compact structure. Alternatively, a light emitting element may be mounted on the circuit board so as to illuminate the space.

  As described above, according to the present invention, it is possible to provide a rotary switch that can change the click feeling and can be easily multi-functionalized without significantly increasing the size of the entire apparatus.

  Next, the assembly process of this composite switch will be described. As will be described below, the composite switch of this embodiment can be assembled from one direction.

  First, the circuit board 71 on which the rotation detector 72 and the press detector 73 are mounted is prepared. Then, until the rear end portion of the substrate contact portion 51c comes into contact with the surface side of the circuit board 71, the first holding portion 54a becomes the first through hole 71a and the second holding portion 54b becomes the second through hole 71b, respectively. insert. Thereby, the holder 50 is fixed to the circuit board 71. At this time, the position of the transmission shaft insertion hole 53d of the holder 50 and the positions of the transmission shaft fitting hole 72a and the transmission shaft insertion hole 71c overlap in a direction parallel to the rotation shaft.

  Next, the click member 60 has a holding part on the side corresponding to a desired uneven pattern among the first uneven pattern 33a and the second uneven pattern 33b, that is, the first holding part 54a and the second holding part 54b. It arrange | positions so that it may be accommodated in the holding part of any one of them.

  Then, the rotational power transmission member 80 is disposed in the rotational power transmission member disposition portion so that the transmission shaft 82 is inserted into the transmission shaft insertion hole 53d, the transmission shaft fitting hole 72a, and the transmission shaft insertion hole 71c. Note that the rotation transmission member 80 may be arranged prior to the assembly of the click member 60 or at the same time as the assembly of the click member 60.

  Subsequently, the dial connection portion 31 is externally fitted to the inner cylinder portion 51 of the holder 50 until the claw 51 a of the holder 50 is engaged on the front end side of the dial connection portion 31. At this time, the claw 51a is deflected inward by being pushed by the inner peripheral surface of the dial connecting portion 31 during the insertion, and returns to the neutral position due to its elasticity when the insertion is completed and is moved to the front end of the dial connecting portion 31. Engage. At this time, the locking portion 61b of the click member 60 is pressed against the uneven pattern, and the transmission portion 34 of the inner 30 and the transmission gear 81 of the rotational force transmission member 80 are engaged.

  Then, the pressing operation member 40 is inserted into the space inside the inner cylinder portion 51 of the holder 50.

  Finally, the dial 20 is externally fitted to the inner 30 until the locked portion 21a of the gripped portion 21 and the locking portion 31a of the dial connection portion 31 engage with each other, so that both are integrated. At that time, the positioning groove 21c of the gripped portion 21 is externally fitted in a posture capable of receiving the positioning protrusion 31b of the dial connection portion 31. The connection of the dial 20 to the inner 30 may precede the insertion of the pressing operation member 40 or may be simultaneous with the insertion of the pressing operation member 40.

  Next, the operation of the composite switch of this embodiment will be described. First, the operation of the rotary switch will be described.

  When the gripped portion 21 of the dial 20 is gripped and the dial 20 is rotated, the inner 30 rotates together with the dial 20. The dial 20 and the inner 30, that is, the rotation operation member 10 rotates relative to the holder 50. Therefore, when the dial 20 is turned, the locking portion 61b of the click member 60 comes out of the predetermined locked recess and rides on the middle part to the adjacent locked recess. At this time, the click spring 62 is deformed so as to be compressed in the rotation axis direction. Further, strain energy is accumulated in the click spring 62 in this state.

  Further, by further rotating the dial 20, the click spring 62 engages with the adjacent recessed portion to be locked while eliminating the displacement. At this time, since the strain energy accumulated in the click spring 62 is released, the operator feels a clear click feeling.

  Further, by rotating the dial 20 so that the locking portion 61b of the click member 60 reaches a locked recess adjacent to the predetermined locked recess, the transmission gear 81 that meshes with the transmission portion 34 rotates. This rotational force is transmitted to the rotation detector 72. At this time, the rotation detector 72 outputs a predetermined signal. That is, the output of the rotation detector 72 is switched each time the operator feels a click by operating the rotation operation member 10.

  Next, the operation of the push switch will be described.

  When the pressed portion 42 of the pressing operation member 40 is pressed, the pusher 44 presses the plunger 73 a of the press detector 73. At this time, the press detector 73 outputs a predetermined signal. For example, this push switch can be used as means for determining a predetermined function selected by a rotary switch.

  As described above, in the rotary switch of the present embodiment, the rotation operation member 10 has the first uneven pattern 33a and the second uneven pattern 33b that rotate around the rotation axis by the rotation operation, and the holder 50 is The first holding part 54a that holds the click member 60 so as to elastically contact the first uneven pattern 33a, and the second holding part that holds the click member 60 so as to elastically contact the second uneven pattern 33b. 54b, the click feeling can be easily changed simply by holding the click member 60 in any one of the holding portions corresponding to the uneven pattern that generates the desired click feeling.

  Further, in the present embodiment, the rotation operation member 10 has a cylindrical body that surrounds the rotation axis so as to form a predetermined space in the vicinity of the rotation axis, and the first uneven pattern 33a, the second uneven pattern 33b, Since the rotational power transmission member 80 is arranged along the radial direction from the outer peripheral surface of the cylindrical body, a member for another function such as a pressing operation member 40 or a lighting device constituting a push switch in the space. Can be incorporated. In addition, the rotational power transmission member 80 is disposed at a position overlapping at least a part of the first concavo-convex pattern 33a and the second concavo-convex pattern 33b when viewed from the direction parallel to the rotation axis. Both concavo-convex patterns and the rotational power transmission member can be arranged outside the cylindrical body while suppressing the size.

  In this embodiment, in addition to the transmission shaft 82 of the rotational force transmission member 80, the first holding portion 54a and the second holding portion 54b also extend in a direction parallel to the rotation axis, so that the radial dimension of the rotary switch is reduced. Further suppression is possible.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and further includes all modifications within the meaning and scope equivalent to the scope of claims for patent.

  For example, in the above-described embodiment, an example in which each of the concave and convex patterns 33a and 33b, each of the holding portions 54a and 54b, and each of the through holes 71a and 71b is provided is shown, but three or more of each may be provided. Good.

  In the above embodiment, an example in which the push switch having the pressing operation member 40 and the pressing detector 73 is provided in the space inside the cylindrical body has been described, but an illumination device having a light source and a display member may be provided. Good. Specifically, a light source such as an LED may be provided instead of the press detector 73, and a display member having a display unit on the front end side may be provided instead of the pressing operation member 40. In this case, the display member is preferably made of a light guide member.
