BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rotationally operated electrical component suitable for electronic equipment, such as for vehicle mounting, in which an operation area is desired to be compact. In particular, the present invention relates to a rotationally operated electrical component capable of two types of rotational operations by the same operating member. will be.

BACKGROUND ART Conventionally, a hybrid operation type electric component capable of performing two types of rotational operations and push operations has been known for in-vehicle acoustic devices and the like (see Patent Document 1, for example). In such a prior art, the inner shaft member is inserted into the hollow portion of the rotatable outer shaft member so as to be rotatable and reciprocally movable along the axial direction, and a push type switch element is provided inside the axial direction of the inner shaft member. The outer shaft member is connected to a first rotating body having a movable contact, and the first rotating body opposes the insulating gas in which the sliding member is formed, so that when the outer shaft member is rotated, the sliding member relatively slides with respect to the movable contact. It is. On the other hand, the inner shaft member is connected to a second rotating body having a movable contact, and the second rotating body opposes an insulated case in which the sliding member is disposed, and when the inner shaft member is rotated, the sliding member is relatively relative to the movable contact. It is supposed to slide. Moreover, this inner shaft member is connected with the drive body which opposes the said switch element, and when the inner shaft member is pushed a predetermined stroke inwardly in the axial direction, the switch element is press-driven by the drive body. As for the electrical component comprised in this way, a 1st detection signal is obtained by the rotation operation with respect to an outer-axis member, a 2nd detection signal is obtained by the rotation operation with respect to an inner-axis member, and it is possible to push operation with respect to an internal-axis member. The third detection signal is obtained by this.

As described above, when the inner shaft member is rotatably inserted in the hollow portion of the rotatable outer shaft member, both shaft members can be selectively rotated, and thus, a compact rotation operation capable of performing two types of rotation operations. Although the electric component can be realized, it is difficult to say that the operability is good because the user has to change the outer shaft member and the inner shaft member when performing two types of rotation operations in succession. Moreover, in this prior art, since the hollow part of an outer shaft member is hard to be used as a light guide path, and it is difficult to form a light control area in the whole surface of an inner shaft member, there existed a problem that it was difficult to improve visibility in a dark place. Moreover, in this prior art, even if there is a space which forms a display portion such as a letter or a symbol on the front surface of the inner shaft member, when the inner shaft member is rotated, the display portion also rotates and the designability is impaired. Has been difficult to use as a display space.

This invention is made | formed in view of such a fact of the prior art, and the objective is the rotation operation type electric component which can perform two types of rotation operation, and is excellent in operability, and also easy to secure a dimming area | region and display space. Is to provide.

In order to achieve the above object, in the rotationally operated electrical component of the present invention, a housing having a cylindrical guide wall, and extrapolated so as to be rotatable to the guide wall, the first operation relatively forward along the axial direction. A hollow drive shaft capable of reciprocating between a position and an inner second operating position, an elastic member that always elastically supports the hollow drive shaft toward the first operating position, and a first that can be engaged with or separated from the hollow drive shaft And a rotation member and a second rotation member, first rotation detection means for detecting rotation of the first rotation member, and second rotation detection means for detecting rotation of the second rotation member, wherein the hollow drive shaft includes: The first rotating member can be moved from the first operating position to the second operating position by a pressing operation force that resists the elastic member. The hollow drive shaft is engaged with the hollow drive shaft when the hollow drive shaft is held at the first operating position and is rotatable integrally, and the second rotating member is the hollow drive shaft when the hollow drive shaft is held at the second operating position. It was set as the structure which was able to engage with and rotate integrally.

In the rotationally operated electrical component configured as described above, the hollow drive shaft is engaged with the first rotating member in the first operating position when the pressing operation force is not applied. Therefore, when the hollow driving shaft is rotated in this state, the first rotating member is rotated. Rotates integrally, and thus a signal according to the rotational operation can be extracted from the first rotation detecting means. Moreover, when the hollow drive shaft in a 1st operating position is moved to a 2nd operation position by the press operation force which resists an elastic member, the engagement of a hollow drive shaft and a 1st rotating member will be canceled, but the hollow which reached the 2nd operation position will be Since the drive shaft is engaged with the second rotating member, when the hollow drive shaft is rotated in this pressing state (ie, by pressing and turning the hollow drive shaft), the second rotating member rotates integrally, thus rotating the signal according to the rotating operation to the second rotation. It can extract from a detection means. Then, when the pressing operation force on the hollow drive shaft is removed, the elastic drive is elastically supported so that the hollow drive shaft automatically returns to the first operating position, so that the engagement between the hollow drive shaft and the second rotating member is released.

That is, the above-described rotation operation type electric parts can selectively arrange the hollow drive shaft in two kinds of rotation operation positions, namely, the first operation position and the second operation position, by pressing operation, and are independent of each operation position. Rotation detection can be performed. Therefore, when performing two types of rotation operations continuously, a user does not need to change an operation member (hollow drive shaft or the handle attached to the drive shaft, etc.), and operability improves significantly. In addition, since the hollow drive shaft is externally inserted into the cylindrical guide wall, the first and second rotation members, the first and second rotation detection means, the elastic member, and the like are all spaces in the radially outer side (outer peripheral side) of the guide wall. In this case, the inner space (hollow part) of the guide wall in the radial direction can be used as a light guide path, or a separate part such as a push switch can be easily disposed in the hollow part, thereby securing a dimming area and a display space. It becomes easy to do it.

In the above configuration, by providing a return spring for automatically returning the second rotating member to the neutral position in the rotational direction, the hollow drive shaft engaged with the second rotating member is also provided when the second rotating member has a self-return function. Since it is pushed back to the neutral position before rotation operation, when this hollow drive shaft is pushed back to a 1st operation position by an elastic member, it is easy to engage with a 1st rotation member again, and it is preferable.

In this case, the housing has a first case having an opening through which the guide wall is loosely fitted and a first rotating member is disposed around the opening, a second rotating member and a guide wall protrudingly installed around the opening. If the structure is provided with the 2nd case in which a return spring is arrange | positioned, since the structure of each case can be simplified and an assembly work can also be simplified, it is preferable. In addition, the end of the return spring is formed on the second case to form a spring support projection which can be locked, and a nodule is formed on the second rotation member to avoid interference with the spring support projection, and rotates with respect to the second rotation member. If the end of the return spring is separated from the spring support projection by the operating force, the return spring can be easily mounted after placing the second rotating member in the second case at the time of assembly, thereby further improving the assembly performance. do.

Moreover, in the said structure, the 1st rotation member arrange | positions the some engaging part which can be engaged with or isolate | separated from a hollow drive shaft, is arrange | positioned so that it may shift by a predetermined angle in the circumferential direction, and In the 2nd case, If the stopper part which restricts the allowable rotation amount of the 2 rotating members to the angle smaller than the said predetermined angle is formed, it will return to a 1st operation position, when the pushing operation force which hold | maintained the hollow drive shaft in the 2nd operation position, and was rotated was removed. The returned hollow drive shaft can be reliably engaged with the first rotating member.

Moreover, in the said structure, a 1st rotation detection means consists of the sliding pattern attached to the contact pattern on the contact pattern and the contact pattern formed in the 1st case, and attached to the 1st rotation member, and 2nd rotation detection means When the contact pattern formed in this 2nd case and the contact pattern on this contact pattern are made sliding, and it is set as the structure comprised by the sliding member attached to the 2nd rotation member, a 1st and 2nd rotation detection means can be made simple. Moreover, since the 1st rotation detection means and the 2nd rotation detection means can be arrange | positioned along the rotation axis direction of a hollow drive shaft, it becomes possible to respond to the request of downsizing.

In the above configuration, if the hollow drive shaft is provided with a spring member that engages or separates from a part of the hollow drive shaft and generates a click feeling while moving from the first operating position to the second operating position, Since the forward and backward motions (reciprocating motion along the axial direction) can be clearly understood, further improvement in operability is achieved.

As shown in FIG. 2, at the time of non-operation, the hollow drive shaft 15 is hold | maintained in the position (1st operation position) clamped by the coil spring 16 and the mounting plate 4, At this time, the engagement recessed part 15b is engaged with the engagement convex part 7b of the 1st rotation member 7. As shown in FIG. In addition, when the hollow drive shaft 15 in the first operating position is pressed against the coil spring 16 and pressed inward in the axial direction, as shown in FIG. 3, the engagement toothed portion of the hollow drive shaft 15 is an engaging portion. 15d is movable to the position (second operation position) which engages with the tooth | gear part 13d (exactly, the recessed part of tooth | gear part 13d) which is the engagement part of the 2nd rotating member 13. As shown in FIG.

The intermediate case 3 is formed in an annular shape having an opening 3a in which the guide wall 2a is loosely fitted. The annular wall 3b is formed in the outer peripheral part of the intermediate | middle case 3, and the positioning pin 3c protrudes in two places of the front surface of this annular wall 3b. The front surface of the annular wall 3b is the surface which overlaps with the back surface of the 1st case 1, and the positioning pin 3c is inserted into the unshown positioning hole formed in the back surface, and both cases 1 and 3 are carried out. Is positioned. Engaging step portions 3d are formed at plural places on the outer circumferential surface of the annular wall 3b, and the leg pieces 4a of the mounting plate 4 are fitted into the engaging step portions 3d. Moreover, the spring support part 3e into which the rear end part of the coil spring 16 is inserted is formed in the inner peripheral part of the intermediate case 3.

The guide wall 2a which penetrates each opening 1a, 3a, 4b is protruded in the center part of the 2nd case 2, and is guided by this guide wall 2a, and the rotational operation of the hollow drive shaft 15 is carried out. And forward and backward motions (reciprocating along the axial direction) are performed. The annular wall 2b is formed in the outer periphery part of the 2nd case 2, and the positioning pin 2c protrudes in two places of the front surface of this annular wall 2b. The front surface of the annular wall 2b is a surface which overlaps with the back surface of the intermediate case 3, and the positioning pin 2c is inserted into the positioning hole which is not shown in the back surface, and both cases 2 and 3 are positioned It is decided. A plurality of engaging stepped portions 2d are formed at a plurality of places on the outer circumferential surface of the annular wall 2b, and the leg pieces 4a of the mounting plate 4 fitted in the engaging end 2d are provided in the second case ( It is caulked to the back of 2). Moreover, the stopper part 2e which can contact the drive wall 13c of the 2nd rotating member 13 is formed in the inner peripheral surface of the annular wall 2b, and this stopper part 2e has the 2nd rotating member ( The permissible amount of rotation of 13) is regulated to an angle sufficiently small (for example, ± about 30 degrees) compared with the dispersion angle (for example, 90 degrees) of the engagement convex portion 7b. A pair of spring receiving protrusions 2f are formed in the inner bottom of the second case 2. As shown in Fig. 11A, both ends of the return spring 14 are caught by the respective spring support projections 2f at the time of non-operation, and the return spring 14 is accompanied by the rotation of the second rotating member 13. ) Elastically stretches, so that one end of the return spring 14 is separated from the spring support projection 2f as shown in FIG. 11 (b). Moreover, the fall prevention protrusion 2g for preventing the fall of the operating body 22 mentioned later is formed in the inner peripheral surface of the guide wall 2a. Moreover, the contact pattern 10 (refer FIG. 12) for rotary switches exposed to the inner bottom part of the 2nd case 2, and the terminal 11 guide | induced to the exterior from the contact pattern 10 are the 2nd by insert molding. It is formed integrally with the case (2).

The second rotating member 13 inserted into the space in the second case 2 has a shape having a pair of cutout windows 13b and a pair of drive walls 13c around the cylindrical portion 13a (Fig. 9 and 10). In the front end of the cylindrical part 13a, the tooth part 13d which can couple | engage with or isolate | separate from the engaging tooth part 15d of the hollow drive shaft 15 is formed over the whole circumference. The return spring 14 is inserted around the cylindrical portion 13a, and both ends of the return spring 14 can engage with the drive wall 13c. As shown in Fig. 11A, since the spring support protrusion 2f of the second case 2 penetrates through the notch window 13b, both ends of the return spring 14 are spring support protrusions 2f. Can be caught by And when the 2nd rotating member 13 rotates, either drive wall 13c will push in one end part of the return spring 14, and extend | stretch along either direction of rotation. However, when the 2nd rotation member 13 rotates a predetermined amount, since the drive wall 13c abuts the stopper part 2e, as shown to FIG. 11 (b), the 2nd rotation member 13 will be moved further. It is not possible to rotate, and the rotation angle of the 2nd rotation member 13 is regulated by this. In addition, the sliding member 12 attached to the back side of the second rotating member 13 is in sliding contact with the contact pattern 10, and the ON signal is transmitted to the terminal 11 when the rotating member 13 rotates by a predetermined amount. Since it is output from the contact pattern 10 and the sliding element 12, the 2nd rotation detection means comprises the 2nd rotation detection means.

The rotationally operated electrical component configured as described above can be assembled in the following order. That is, first, the second rotating member 13 is inserted into the space between the guide wall 2a and the annular wall 2b of the second case 2, and penetrates through the spring support protrusion 2f in the notch window 13b. After that, both ends of the return spring 14 disposed around the cylindrical portion 13a are hooked to the spring support projection 2f. Subsequently, after stacking and positioning the intermediate case 3 on the second case 2 to cover the return spring 14 or the drive wall 13c, the coil spring 16 and the hollow drive shaft 15 are sequentially While extrapolating to the guide wall 2a, the 1st case 1 is laminated | stacked on the intermediate case 3, and is positioned. And after inserting the 1st rotation member 7 and the click spring 9 in the 1st case 1 sequentially, the leg piece 4a of the mounting plate 4 laminated | stacked so that the 1st case 1 may be covered. ) Is inserted into the engagement stepped portions 1c, 3d, and 2d and caulked to fix the respective cases 1 to 3 to integrate the assembly.

Next, operation | movement of this rotation operation type electrical component is demonstrated. As shown in FIG. 2, the hollow drive shaft 15 is hold | maintained in the 1st operation position, when the press operation force is not provided (non-operation | operation), and the engagement recessed part 15b of the hollow drive shaft 15 is The engagement convex part 7b of the 1st rotating member 7 is engaged. Therefore, when the user rotates the hollow drive shaft 15 in this state, since the first rotating member 7 rotates integrally, the contact position of the sliding member 8 with respect to the contact pattern 5 changes, The pulse signal of the rotary encoder according to the rotational operation of the hollow drive shaft 15 is output from the terminal 6.

As shown in Fig. 3, when the user pushes the hollow drive shaft 15 at the first operation position against the coil spring 16 and pushes it inward in the axial direction to move to the second operation position, the hollow drive shaft ( The engagement of the 15 and the first rotating member 7 is released, but the engaging toothed portion 15d of the hollow drive shaft 15 is the toothed portion 13d of the second rotating member 13 in the second operating position. Is engaged with. Therefore, when the hollow drive shaft 15 is rotated against the return spring 14 in the pressing state (that is, the hollow drive shaft 15 is pushed out), the second rotating member 13 is integrally rotated so that the contact is made. Since the contact position of the sliding element 12 with respect to the pattern 10 changes, the ON signal of the rotary switch according to the rotation operation of the hollow drive shaft 15 is output from the terminal 11.

In addition, since the drive wall 13c drives one end of the return spring 14 with the rotation of the second rotating member 13, as shown in FIG. 11 (b), the return spring 14 is one-sided. It extends elastically apart from the spring support protrusion 2f. Moreover, when the operating force with respect to the hollow drive shaft 15 is removed in a 2nd operation position, since the return spring 14 will elastically return and will push back the drive wall 13c, the 2nd rotating member 13 will be FIG. 11 (a). Since the coil spring 16 is elastically returned and the hollow drive shaft 15 is pushed back to the first operating position, the hollow drive shaft 15 is in contact with the second rotating member 13. The engagement is released and again engaged with the first rotating member 7.

Next, as a specific use example of the above-mentioned rotary operation type electric component, as shown in FIG. 4, the push switch 21 and its operating body (in the space (hollow part) inside the radial direction of the guide wall 2a) ( 22) The composite operation type electrical component which arrange | positioned is demonstrated. As shown in the figure, this composite operation type electrical component is mounted on the circuit board 20. The push switch 21 and LED 23 are arrange | positioned on the circuit board 20, and a part of the operating body 22 which consists of a translucent resin material protrudes forward from the guide wall 2a. While the stem part 22a is mounted on the push switch 21, this operating body 22 is prevented from falling off from the guide wall 2a by the fall prevention protrusion 2g, and the push switch An unshown return spring, which is incorporated in the 21, elastically supports the operating body 22 all the time. The thin part 22b of the operating body 22 opposes the LED 23, and the front surface of the thin part 22b is a light control area. Moreover, the operation knob 24 is attached to the front end of the hollow drive shaft 15, and this operation knob 24 is caught by the locking hole 15a of the hollow drive shaft 15. As shown in FIG. In addition, the terminals 6 and 11 are soldered to a wiring pattern (not shown) formed on the circuit board 20.

In the composite operation type electric component shown in FIG. 4, since the operation knob 24 is integrated with the hollow drive shaft 15, the user can use the first rotation member 7 and the second rotation member via the operation knob 24. The 13 can be selectively rotated, and the user can press-operate the push switch 21 via the operating body 22. In addition, since the front surface of the thin portion 22b of the operating body 22 is a dimming area, visibility is good in a dark place, and a character is displayed on the front surface of the operating body 22 which does not rotate during operation. Even if the display portion such as a symbol or the like is formed, the design is not impaired.

Thus, in the rotation operation type electric component which concerns on the example of this embodiment, the hollow drive shaft 15 can be selectively arrange | positioned at two types of rotation operation positions, a 1st operation position and a 2nd operation position, Since independent rotation detection can be performed, the user does not need to change the operation member (for example, the operation knob 24 mounted on the hollow drive shaft 15) when performing two types of rotation operations in succession, and operability This greatly improves. Moreover, since the hollow drive shaft 15 is extrapolated to the cylindrical guide wall 2a, the 1st and 2nd rotating members 7 and 13, the contact pattern 5 and 10, the coil spring 16, and the return spring ( 14) etc. can all be arrange | positioned in the space of the radial direction outer side of the guide wall 2a. As a result, as shown in FIG. 4, using the space (hollow part) inside the radial direction of the guide wall 2a as a light guide path, or arrange | positioning other components, such as the push switch 21 in the hollow part, It becomes easy, and it becomes easy to ensure a light control area and a display space.

Moreover, in the rotation operation type electrical component which concerns on the example of this embodiment, the 1st case 1 in which the 1st rotation member 7 is arrange | positioned, and the guide wall 2a are protruded, and the 2nd rotation member 13 is carried out. The housing is constituted by a second case 2 in which the return spring 14 is disposed and an intermediate case 3 in which the coil spring 16 is disposed between the first and second cases 1 and 2. Since the structure of each case 1-3 is simple, it is easy to shape | mold and the assembly work is also simplified. For example, the second rotating member 13 needs to be inserted so as to be rotatable in response to the elastic force of the return spring 14, and in the assembly of this rotationally operated electrical component, the second rotating member 13 is formed in the second case 2. After arranging the 2 rotating members 13, since both ends of the return spring 14 extrapolated to the cylindrical part 13a need only be caught by the spring support protrusion 2f which penetrates the notch window 13b, The rotating member 13 and the return spring 14 can be inserted easily.

Moreover, in the rotation operation type electrical component which concerns on the example of this embodiment, when the operation force with respect to the hollow drive shaft 15 is removed in a 2nd operation position, the return spring 14 will be before the rotation operation of the 2nd rotation member 13, Since the coil spring 16 adopts a self-return mechanism for automatically returning to the position and pushing the hollow drive shaft 15 back to the first operating position, the hollow returned to the first operating position from the second operating position. The engagement concave portion 15b of the drive shaft 15 is easily engaged with the engagement convex portion 7b of the first rotation member 7 again. In particular, in the present embodiment, the allowable rotational amount of the second rotating member 13 is sufficiently small compared to the dispersion angle of the engaging convex portion 7b by the stopper portion 2e that can contact the drive wall 13c. Since it restrict | limits by an angle, when the pushing operation force which rotated by holding the hollow drive shaft 15 in the 2nd operation position is removed, the 1st rotation member reliably returns the hollow drive shaft 15 which returned to the 1st operation position. Can be aligned with (7).

In addition, although FIG. 4 shows the use example which arrange | positioned the push switch 21, the operating body 22, etc. in the space (hollow part) of radial direction inner side of the guide wall 2a, the use method of the hollow part is suitably shown. It is selectable, for example, by arranging a light guide or the like in the hollow portion, the front surface of the hollow portion can also be used as a display-only space (non-operating region) which also serves as a dimming region.

Moreover, when the click line spring 17 as shown in FIG. 13 is added to the rotation operation type electric component which concerns on the example of this embodiment, the forward-backward motion (reciprocating movement along an axial direction) of the hollow drive shaft 15 is performed. Since it becomes possible to detect clearly, the further improvement of operability is aimed at. That is, the hollow drive shaft 15 is inserted while the click line spring 17 is inserted into the back side of the first case 1, for example, and the hollow drive shaft 15 moves from the first operating position to the second operating position. When the projections and the like on the outer circumferential surface of the slit engage with or separate from the click line spring 17 to generate a click feeling, the user moves the hollow drive shaft 15 to the second operation position by the click feeling transmitted to the finger. Since it can be clearly understood, misoperation can be prevented beforehand.

According to the rotationally operated electrical component of the present invention, by a pressing operation, the hollow drive shaft can be selectively disposed at two kinds of rotational operation positions, namely, a first operation position and a second operation position, and independent rotation detection is performed at each operation position. We can do it. For this reason, when performing two types of rotation operations successively, a user does not need to change an operation member (hollow drive shaft or the handle attached to the drive shaft, etc.), and operability is largely improved. In addition, since the hollow drive shaft is extrapolated to the cylindrical guide wall, the first and second rotating members, the first and second rotation detecting means, the elastic member, and the like are all spaces in the radially outer side (outer peripheral side) of the guide wall. Therefore, it is easy to use the space (hollow part) of the radially inner side of a guide wall as a light guide path, or to arrange another part, such as a push switch, in the hollow part, and to adjust a dimming area | region and a display space. It is easy to secure.
