JP 2001-184969 A

  As shown in FIG. 4, the present inventor rotates the main driving gear 30x with the dial 10x in the operating device in which the dial 10x and the knob 20x are arranged side by side and the knob 20x is transmitted and illuminated by the light source 80x. The sensor 50x detects the amount of rotation of the driven gear 40x that engages the motor.

  In this way, when the knob 20x is transmitted and illuminated, the reflector 72x is disposed on the back side (opposite the user) of the knob 20x, and the light from the light source 80x is reflected toward the incident surface 21ax of the knob 20x. Cost. This prevents light from leaking out from locations other than the knob 20x and being visually recognized by the user.

  In addition, a partition plate 71x that partitions the sensor 50x side and the main driving gear 30x side is integrally formed of resin together with the reflector 72x, and the driven gear 40x is inserted and held by the through hole 71ax of the partition plate 71x.

  However, in the structure shown in FIG. 4, an insertion space for inserting the driven gear 40x into the through hole 71ax (see the two-dot chain line in the figure) must be secured, so that the upper portion of the driven gear 40x (insertion space) is required. There is a restriction that the reflector 72x cannot be positioned. As a result, the knob 20x cannot be positioned at the upper part of the driven gear 40x, and as a result, there arises a problem that the gap CL between the dial 10x and the knob 20x becomes large. For this reason, the dial 10x and the knob 20x cannot be disposed close to each other, and in some cases, a blindfold member 90x that fills the gap CL is necessary.

  The present invention has been made in view of the above problems, and an object of the present invention is to arrange a rotary operation body having a structure for detecting the rotation amount by rotation of a driven gear and a push operation body to be transmitted and illuminated. It is an object of the present invention to provide an operating device that makes it possible.

  One disclosed invention employs the following technical means to achieve the above object. In addition, the code | symbol in the parenthesis described in the claim shows the correspondence with the specific means as described in embodiment mentioned later as one aspect, Comprising: The technical scope of the disclosed invention is limited Not what you want.

One of the disclosed inventions is an operation device including a push operation body (20) that is pushed and operated by a user and is transmitted and illuminated, and a rotary operation body (10) that is rotated by a user. A main drive gear (30) that rotates by the rotation operation force of the rotary operation body, and a driven gear (40) that engages and rotates with the main drive gear and detects the rotation amount by the rotation amount detection means (50). A reflector (72) that reflects light emitted from the light source (80) and guides it to the incident surface (21a) of the push operating body, and is formed of a resin integrally with the reflector, and the rotation shaft of the driven gear A through hole (71a) into which the portion (42) is inserted is formed, and a partition plate (71) for partitioning the rotation amount detecting means side and the main driving gear side is provided.

  And, the diameter of the through hole is formed larger than the diameter of the driven gear portion (41) engaged with the main driving gear among the driven gears, so that the rotation gear detecting means side to the main driving gear side. The driven gear portion is configured to be insertable into the through hole.

  According to this, since the driven gear is inserted into the through hole from the rotation amount detecting means side, the driven gear is inserted into the through hole at the upper portion of the driven gear, that is, the space opposite to the partition plate with respect to the driven gear. It is unnecessary to secure an insertion space for insertion. Therefore, the reflector can be positioned on the driven gear, so that the knob can be positioned on the driven gear 40x. Therefore, it is possible to arrange the rotation operation body having a structure for detecting the rotation amount by the rotation of the driven gear and the push operation body to be transmitted and illuminated close to each other.

The front view which shows the state by which the operating device which concerns on 1st Embodiment of this invention was mounted in the instrument panel in a vehicle interior. II-II sectional drawing of FIG. Sectional drawing which shows the operating device which concerns on 2nd Embodiment of this invention. Sectional drawing which shows the operating device of the structure used as the comparison object of this invention.

  Hereinafter, each embodiment in which an operating device according to the present invention is applied to a vehicle operating device will be described with reference to the drawings. In each of the following embodiments, configurations of portions denoted by the same reference numerals in the drawings are the same or equivalent to each other, and the description thereof is cited.

(First embodiment)
The operating device of this embodiment shown in FIG. 1 is mounted on an instrument panel 1 provided in a vehicle interior, and includes a plurality of dials 10 (rotating operation bodies) and knobs 20 (pushing operation bodies). ing. FIG. 1 shows a portion of the operating device so that one dial 10 and one knob 20 are shown. The dial 10 has a cylindrical gripping portion 10a shown in FIG. 2, and is configured such that the user grips the outer peripheral surface of the gripping portion 10a with a finger and rotates it as indicated by an arrow Y1 in the drawing. ing.

  The knob 20 is pushed by the user from the near side to the far side of the instrument panel 1 (see arrow Y2 in FIG. 2). In the example of FIG. 1, the present invention is applied to an operating device that operates an in-vehicle air conditioner. For example, the dial 10 operates an air conditioning set temperature in the passenger compartment, and the knob 20 performs an on / off operation to drive and stop the air conditioner. To do.

  The plurality of dials 10 and the knob 20 are arranged side by side along the design surface of the instrument panel 1. In the case of the instrument panel 1 of a vehicle, since the space for mounting the dial 10 and the knob 20 is limited, there is a high demand for reducing the distance CL between the dial 10 and the knob 20. Moreover, the request | requirement which makes the said clearance CL small is also high also in the meaning which raises the freedom degree of the arrangement layout of the dial 10 and the knob 20.

  As shown in FIG. 2, the operating device includes a main driving gear 30, a driven gear 40, an encoder 50 (rotation amount detection means), a circuit board 60, a partition plate 71, reflectors 72 and 73, and a light source 80 described below.

  The main driving gear 30 is attached to the dial 10 and is rotated by the rotational operation force of the dial 10. Specifically, the main driving gear 30 is attached to the inner peripheral surface of the grip portion 10a so that the rotation center of the main driving gear 30 and the rotation center of the dial 10 coincide. In the example of FIG. 2, the main driving gear 30 and the dial 10 are separately resin-molded, but the main driving gear 30 and the dial 10 may be formed as a single component by integrally resin-molding.

  The main driving gear portion 31 formed on the main driving gear 30 engages with the driven gear portion 41 formed on the driven gear 40 to rotate the driven gear 40. Since the diameter of the main gear 31 is set larger than the diameter of the driven gear 41, the amount of rotation of the driven gear 40 is larger than the amount of rotation of the main gear 30 and the dial 10.

  The gears 30 and 40 are arranged so that the rotation center of the main driving gear 30 does not coincide with the rotation center of the driven gear 40 and these rotation centers are parallel to each other. The engaging position of both the gear parts 31 and 41 is located in the radial direction outer side than the outer peripheral surface of the holding part 10a. Further, the driven gear 40 is arranged so that the rotation center of the driven gear 40 is located at a position overlapping the knob 20 in the front view shown in FIG. The dial 10 and the knob 20 are arranged side by side in the radial direction of the driven gear 40.

  The driven gear 40 includes a driven gear part 41, a rotating shaft part 42, a cover part 43, and an annular convex part 43a, which are integrally formed of resin. A driven gear portion 41 is provided at one end of the rotating shaft portion 42, and an encoder 50 is attached to the other end. The encoder 50 detects the amount of rotation of the driven gear 40. That is, the rotation operation amount of the dial 10 with respect to the reference position is detected.

  The encoder 50 is mounted on the opposite side of the main drive gear 30 in the circuit board 60, the partition plate 71 is disposed on the opposite side of the encoder 50 with respect to the circuit board 60, and both gear portions 31 and 41 are in relation to the partition plate 71. And disposed on the opposite side of the encoder 50. In short, the partition plate 71 partitions the internal space of the operating device into the encoder 50 side and the gear portions 31 and 41 side.

  The driven gear 40 is positioned on one side of the partition plate 71 by inserting the rotating shaft portion 42 into the through hole 71 a of the partition plate 71 and the through hole 60 a of the circuit board 60 and arranging the driven gear 40. The rotation of the main driving gear 30 is transmitted to the encoder 50 located on the other side.

  The diameter of the through hole 71 a is formed larger than the diameter of the driven gear portion 41. Accordingly, the driven gear portion 41 can be inserted into the through hole 71a from the encoder 50 side to the main driving gear 30 side. The cover part 43 is located on the encoder 50 side with respect to the partition plate 71 so as to cover the through hole 71a from the encoder 50 side. The cover part 43 has a disk shape, and the diameter of the disk is larger than the diameter of the through hole 71a.

  An annular convex portion 43 a that protrudes toward the partition plate 71 is formed on the outer peripheral edge portion of the cover portion 43. The annular protrusion 43 a has a shape extending in an annular circle around the through hole 71 a and is fitted in an annular recess 71 b formed in the partition plate 71. Since the annular convex portion 43a is fitted in contact with the annular concave portion 71b, the annular convex portion 43a slides in the annular concave portion 71b when the driven gear 40 rotates.

  The knob 20 includes an operation unit 21 that is pressed by a finger by the user, and an annular part 22 that extends from the outer edge of the operation unit 21 to the opposite side of the user and surrounds the operation unit 21 in an annular shape. Yes. The operation unit 21 has translucency, and is transmitted and illuminated by a light source 80 mounted on the circuit board 60 (see a wavy arrow in FIG. 2).

  The back surface (opposite surface of the user) of the operation unit 21 corresponds to the incident surface 21a on which the transmitted illumination light is incident, and the reflectors 72 and 73 reflect the light toward the incident surface 21a. The light is prevented from leaking to the user without passing through 21a. In addition, the reflector located in the projection part (upper part of the driven gear 40) of the driven gear part 41 in the rotation center line direction of the driven gear 40 is called the gear upper reflector 72, and the reflector located in the other part is the main body reflector 73. Call it.

  The reflectors 72 and 73 have a shape that extends in an annular shape so as to face the inner surface of the annular portion 22, and the annular inner peripheral surface 72 a is printed with a highly light reflective paint. The treatment which raises is given. The main body reflector 73 has a shape extending in the vertical direction of FIG. 2 along the inner surface of the annular portion 22, and the gear upper reflector 72 is formed at the upper portion of the driven gear portion 41 so as to avoid interference with the driven gear portion 41. The shape is inclined with respect to the main body reflector 73. Therefore, in the top view shown in FIG. 1, the shape of the lower end portion A1 of the reflectors 72 and 73 is a shape that avoids interference with the driven gear portion 41, whereas the shape of the upper end portion A2 of the reflectors 72 and 73 is The shape is similar to the outer shape of the operation unit 21.

  A region surrounded by the upper end portion A2 of the operation unit 21 is a transmitted illumination region 21a, and the reflectors 72 and 73 reflect light so that the transmitted illumination region 21a is transmitted and illuminated. In other words, the reflectors 72 and 73 prevent light from leaking to the user side from parts other than the transmitted illumination area 21a. It should be noted that a symbol or a character (not shown) may be printed on the transmitted illumination area 21a of the operation unit 21 so that the printed part is transmitted and illuminated, or the entire transmitted illumination area 21a is illuminated. Also good.

  The annular portion 22 of the knob 20 is held by reflectors 72 and 73 so as to be vertically movable. The dial 10 and the main driving gear 30 are held by the boss member 76 in a rotatable state. The reflectors 72 and 73, the partition plate 71, and the boss member 76 are integrally formed of resin. Therefore, the resin integrated structure functions as a holding member that holds the dial 10, the main driving gear 30, and the knob 20. The dial 10, the main driving gear 30, and the knob 20 are assembled to the resin integrated structure from the opposite side of the circuit board 60.

  In short, the present embodiment described above has the characteristics listed below. And the effect demonstrated below is exhibited by each of those characteristics.

<Feature 1>
By forming the through hole 71a formed in the partition plate 71 larger than the driven gear portion 41, the driven gear portion 41 can be inserted into the through hole 71a from the encoder 50 side.

  Therefore, an insertion space (see the two-dot chain line in FIG. 4) required when the driven gear 40 is inserted into the through hole 71 a from the reflector 72 side can be eliminated, and the reflector 72 is positioned above the driven gear 40. Will be able to. As a result, the transmitted illumination area 21a of the knob 20 can be positioned above the driven gear 40, so that the dial 10 and the knob 20 can be arranged close to each other. Therefore, since the clearance CL between the dial 10 and the knob 20 can be reduced, the degree of freedom in the layout of the dial 10 and the knob 20 can be improved, and the clearance CL is sufficiently reduced to be illustrated in FIG. This eliminates the need for the blindfold member 90x.

<Feature 2>
The driven gear 40 has a cover portion 43 that covers the through hole 71a from the encoder 50 side. Therefore, when the user puts a drink on the instrument panel 1 (design panel), the cover part 43 can suppress moisture from reaching the circuit board 60 through the through hole 71a. In addition, since the cover portion 43 is formed with the annular convex portion 43 a that is fitted into the partition plate 71, it is possible to improve the certainty of avoiding moisture from entering the circuit board 60.

<Feature 3>
Since the driven gear 40 is formed with an annular convex portion 43a that is fitted into the annular concave portion 71b of the partition plate 71, the driven gear 40 is positioned in the radial direction, and the occurrence of poor engagement between the gear portions 31, 41 is suppressed. it can.

(Second Embodiment)
In this embodiment shown in FIG. 3, in addition to the configuration of the first embodiment, a guide portion 74 and a hook portion 75 described below are resin-molded integrally with the partition plate 71.

  The guide portion 74 guides the driven gear 40 to a predetermined position in the radial direction when the driven gear 40 is inserted into the through hole 71a. The guide portion 74 has a shape extending from the outer peripheral edge portion of the through hole 71 a to the reflector 72 side of the partition plate 71. An inner surface 74a of the guide portion 74 (a surface facing the driven gear 40) has a tapered shape that is inclined with respect to the rotation center direction of the driven gear 40 (vertical direction in FIG. 3). In the example of FIG. 3, a plurality of a pair of opposing guide portions 74 are provided, but the guide portions may have a conical shape extending annularly around the rotation shaft portion 42.

  The hook portion 75 has a function of preventing the driven gear 40 from falling out of the through hole 71a toward the encoder 50. The hook portion 75 has a shape extending from the outer peripheral edge portion of the through hole 71 a to the circuit board 60 side in the partition plate 71, and the tip 75 a of the hook portion 75 is formed on the lower surface of the cover portion 43 (the surface on the circuit board 60 side). ).

  In the state of FIG. 3, the hook portion 75 is not elastically deformed. However, when elastically deformed, the tip 75 a can be positioned at a position deviated from the insertion locus of the driven gear 40 into the through hole 71 a. Therefore, if the hook portion 75 is elastically deformed, the driven gear 40 can be inserted into the through hole 71a and assembled, and after the assembly is completed, the hook portion 75 is returned to the natural state and the tip 75a is moved to the cover portion. The lower surface of 43 can be contacted.

  As described above, since the guide portion 74 is provided in the present embodiment, when the driven gear 40 is inserted into the through hole 71 a and assembled at a predetermined position, the driven gear portion 41 is moved to the predetermined radial position by the guide portion 74. Since it is guided, the assembling workability can be improved.

  Further, since the hook portion 75 is provided in the present embodiment, the driven gear 40 can be inserted and assembled from the encoder 50 side into the through hole 71a by elastically deforming the hook portion 75, and the assembly thereof is also possible. After completion, the tip 75a of the hook portion 75 contacts the lower surface of the cover portion 43, so that the driven gear 40 can be prevented from falling off the through hole 71a toward the encoder 50.
