Japanese Laid-Open Patent Publication No. 2003-54290 (pages 3 to 5, Fig. 3)

By the way, in the above conventional combined operation mechanism, since the return operation of the operation member to the rising position is performed by the return spring incorporated in the push switch, the pressurization stroke of the operation member cannot be made that large, but the rotor member By providing a coil spring as a return spring between the rotating member and the operating member and spline coupling the rotor member and the operating member in both axial directions, the pressure stroke of the operating member corresponds to the displacement amount of the coil spring. It becomes possible to set long. However, in the case of adopting such a configuration, since the operation member rises forcefully by the elastic force of the coil spring when the operator removes the press operation force against the operation member, for example, the operation member is attached to the stopper defining the rising position. Is expected to cause a deterioration in quality, such as a strong crash and a collision sound.

In addition, a switch provided with a push lock mechanism capable of locking the stem in a pressurized position has been known in the art. When such a switch with a push lock mechanism is used in place of the above-described push switch, the operation member is locked in the down position when not in use. By pressing the operating member and releasing the lock during use, the operating member can be automatically returned to the lifted position. However, in the case of adopting such a configuration, if external vibration is applied while the operation member is held in the lowered position, the sliding pin, which is a component of the push lock mechanism, is peeled off from the lock of the heart-shaped cam groove, and the operation member is released. It is difficult to securely lock the operation member by using a push lock mechanism, especially in a vehicle-mounted electronic device in which the environment may be easily subjected to large external vibration, such as during bad road driving. .

The present invention has been made in view of the situation of the prior art, and an object thereof is to provide a complex operating mechanism having excellent sense of quality capable of braking the lifting operation of a rotating and pressurized operation member.

In order to achieve the above object, the composite operation mechanism according to the present invention includes a rotation member rotatably supported on a base, an operation member installed to be liftable with respect to the rotation member, and rotationally driving the rotation member; And a ballistic means provided between the rotating member and the operation member, and an operation resistance imparting means for braking the lifting operation of the operation member, wherein the operation resistance imparting means comprises a damper driving means and a damper. One of these damper driving means and a damper was provided to the rotating member, and the other of the damper driving means and damper was provided to the operating member.

In addition, in order to achieve the above object, the composite operation mechanism according to the present invention, the rotation member rotatably supported on the base, the operation member splined to the lifting member with respect to the rotating member, and these rotating members and A return spring provided between the operation member and an operation resistance imparting means for braking the lifting operation of the operation member, wherein the operation resistance imparting means extends in the lifting direction of the operation member and this straight line It consists of a rotary damper which engages with a guide part, and arrange | positions either one of these linear guide parts and a rotary damper to the said rotating member, and it is set as the structure which provided another one to the said operation member.

In the combined operation mechanism configured as described above, when the operator pressurizes the operation member in the ascending position, the operation member moves to the lowered position in response to the spring force of the return spring, and when the pressure operation force is removed from the lowered position, the operation is operated. The member is automatically returned to the lifted position by the spring force of the return spring, and during the lifting operation of the operation member, the rotary damper is engaged with the linear guide part to operate, so that the lifting operation of the operation member is braked. When the operation member is automatically returned to the lifted position, the movement becomes smooth and the operator can feel a sense of quality.

In the above-described configuration, it is preferable that the linear guide portion is composed of a rack in which a plurality of teeth are continuously arranged in the lifting direction of the operation member so that the pinion fixed to the rotating shaft of the rotary damper is engaged with the rack. The slip between the rotary damper and the rotary damper is eliminated, and the brake can be efficiently applied to the lifting operation of the operating member.

In addition, in the above-described configuration, the heart-shaped cam groove is provided on either one of the rotating member and the operating member, and the sliding pin for sliding along the heart-shaped cam groove is provided on one of the other members. The push lock mechanism is constituted by the cam cam groove and the sliding pin, and it is preferable that the push lock mechanism enables the operation member to be locked in the lowered position. In addition to locking, the locking member can be raised at the time of use, and the operating member can be automatically returned to the rising position slowly even by using a return spring with a large spring load, thereby increasing the lock holding force of the push lock mechanism. Therefore, even when the composite operation mechanism is applied to an on-vehicle electronic device that is susceptible to external vibration, the operation member in the lowered position can be prevented from automatically returning to the undesired rising position by external vibration.

In this case, it is preferable to install a protruding wall protruding upward in the center of the rotating member, and to form a rack and a heart-shaped cam groove in the protruding wall, respectively. It is preferable that the mold structure for forming the rotating member can be simplified by forming on the surfaces perpendicular to each other. In addition, the support member vertically descending toward the outside of the protruding wall is vertically installed on the operation member, and when the rotary damper and the sliding pin are respectively supported on the support wall, the operation resistance imparting means is provided within the limited space between the rotation member and the operation member. Each component member of the push lock mechanism can be provided to realize miniaturization of the complex operating mechanism.

(6) is provided. These push switches 6 are respectively operated by the seesaw or pressing operation of the plurality of operation knobs 7 supported by the upper case 2, but since the operation mechanisms are general, detailed description thereof will be omitted here.

The upper case 2 is formed with a circular recess 8 in plan view, and a click groove 8a for detent is formed along the circumferential direction on the outer circumferential surface of the recess 8. Moreover, the perforation hole 8b is formed in the center of the recessed part 8, and the rotor 5a of the rotary encoder 5 has reached the recessed part 8 through this perforation hole 8b. Moreover, the cylindrical body 9 made of synthetic resin is fixed to the upper case 2 using a plurality of screws 10, and a stopper protrusion 9a is formed at the upper end of the outer circumferential surface of the cylindrical body 9. The lower opening end of the cylindrical body 9 continues to the recessed part 8, and the rotating member 11 made of synthetic resin is provided in these recessed part 8 and the cylindrical body 9 inside.

As shown in FIGS. 3-6, this rotating member 11 is a disk-shaped base part 1la, the protrusion wall 11b extended upward from the center part of the base part 11a, and the base part 11a. Has a plurality of guide walls 11c extending upward from an outer edge of the outer edge, and the protruding walls 11b are surrounded by respective guide walls 11c. The base 11a is inserted into the recess 8 of the upper case 2, and the rotor 5a of the rotary encoder 5 protruding into the recess 8 is located at the center of the lower surface of the base 11a. It is fitted to the formed engaging hole 11d. Moreover, a pair of storage holes 11e are formed in the peripheral surface of the base part 11a, and these storage holes 11e are provided in the straight line passing through the center of the base part 11a. As shown in FIG. 1 and FIG. 2, the spring 12 and the drive body 13 are inserted in order in the inside of each storage hole 11e, and the drive body 13 receives the elastic force of the spring 12, and is received. It is press-contacted to the click groove 8a formed in the outer peripheral surface of the recessed part 8. Therefore, when the rotating member 11 rotates clockwise or counterclockwise, the driving body 13 can be caught by the click groove 8a and peeled off to cause detent (theft feel) and the rotor 5a. It is possible to operate the rotary encoder (5) by integrally rotating. In addition, one side of the protruding wall (11b) is formed with a rack 14 extending linearly in the vertical direction, the other side of the protruding wall (11b) perpendicular to the one side is formed a heart-shaped cam groove (15) It is. As shown in FIG. 10, this heart-shaped cam groove 15 has the lock part 15a, the return path 15b, the return path 15c, and the reciprocating path 15d, and connects the return path 15b and the return path 15c. It is an additional lock part 15a. Further, guide grooves 11f extending linearly in the vertical direction are formed in each guide wall 11c.

An operating member 16 made of synthetic resin is splined to the rotating member 11 so as to be lifted and lowered, and a coil spring 17 is provided between the rotating member 11 and the operating member 16. As shown in FIG.7 and FIG.8, this operation member 16 is shape | molded in the cylindrical shape which closed the upper surface and opened the lower end, and the protrusion part 16a is formed in four places of the lower end of the inner peripheral surface. These protrusions 16a are in sliding contact with the outer circumferential surface of the cylindrical body 9, and each of the protrusions 16a abuts against the stopper protrusion 9a of the cylindrical body 9, thereby preventing the operation member 16 from falling off. At the same time, the ascending position is determined. In addition, a supporting wall 16b is vertically provided at the center of the operation member 16, and a plurality of guide protrusions 16c are formed on the outer surface of the supporting wall 16b. Each guide protrusion 16c is inserted into the guide groove 11f of the rotating member 11, whereby the rotating member 11 and the operation member 16 are splined, both of which are movable in the axial direction, The state is integrated in the rotational direction. Therefore, when the operation member 16 is pressed against the repulsive force of the coil spring 17, each of the guide projections 16c descends along the guide groove 11f, so that the operation member 16 is in a fixed state. When the operation member 16 is rotated, but the lowering operation is performed with respect to the rotating member 11, the rotational force is transmitted to the rotating member 11 via the engaging portion of each guide protrusion 16c and the guide groove 11f. Thus, the operation member 16, the coil spring 17 and the rotating member 11 rotate integrally.

As shown in FIG. 1, the pin holder 18 and the rotary damper 19 are supported by the inner surface of the support wall 16b of the operation member 16, These pin holder 18 and the rotary damper 19 are supported. Is opposed to each other via the protruding wall 11b of the rotating member 11. As shown in Fig. 9, the pin holder 18 has a case 20 made of synthetic resin, a sliding pin 21 and a spring 22 which are bent in a crank shape, and the case 20 is pressed or adhered with an adhesive or the like. It is fixed to the inner surface of the support wall 16b. The lower end 21b of the sliding pin 21 is supported by the case 20 so as to be swingable, and the upper end (sliding end) 21a of the sliding pin 21 is subjected to the force of the spring 22 to rotate the rotating member ( Engaged in the heart-shaped cam groove 15 formed in the protruding wall 11b of 11, the push lock mechanism is comprised by these pin holder 18 and the heart-shaped cam groove 15. As shown in FIG. As a result, the sliding end portion 21a moves (slids) along the heart-shaped cam groove 15 as the operation member 16 moves up and down, and the sliding end portion 21a moves to the lock portion 15a of the heart-shaped cam groove 15. When it stops by stopping (refer FIG. 10), the operation member 16 is locked in the downward position.

As shown in FIG. 1 and FIG. 12, the rotary damper 19 has the dish-shaped case 23 which has a pair of mounting leg part 23a, and the cap 24 joined and integrated with this dish-shaped case 23. As shown in FIG. ), The braking rotor 25 provided inside these dish-shaped case 23 and the cap 24, the pinion 26 fixed to the rotating shaft 25a of this braking rotor 25, etc., All of these members are molded from synthetic resin. The dish-shaped case 23 has a circular recess 23b in plan view, and a shaft 23c is placed upright in the center of the recess 23b. The braking rotor 25 is rotatably supported by the shaft 23c, and a pair of braking plate portions 25b protrude from the lower circumferential surface of the rotating shaft 25a. The recessed portion 23b of the dish-shaped case 23 is covered by the cap 24, and a viscous fluid 27 such as silicone oil is injected into the recessed portion 23b and the cap 24. . A center hole 24a is formed in the cap 24, and an upper portion of the rotating shaft 25a protrudes outward through the center hole 24a, but an O-ring 28 is formed at the lower portion of the rotating shaft 25a. By sticking in, the outflow of the viscous fluid 27 is prevented. The pinion 26 has a center hole 26a formed therein, and an upper end portion of the rotation shaft 25a is press-fitted into the center hole 26a. The mounting leg 23a of the dish-shaped case 23 is fixed to the inner surface of the support wall 16b by press fitting or adhesive bonding, and the pinion 26 is provided with a protruding wall (of the rotating member 11). Meshes with the rack 14 formed in 11b). The rack 14 constitutes a linear guide portion, and the rack 14 and the rotary damper 19 are constituted of operation resistance applying means. As a result, when the pinion 26 rotates as the operating member 16 moves up and down, the brake plate 25b of the brake rotor 25 rotates in the viscous fluid 27 to brake the lifting operation of the operating member 16. This is supposed to take.

Next, the operation of the on-vehicle electronic device configured as described above will be described. As shown in FIG. 1, when an operator rotates the operation member 16 in a raised position, the rotational force is transmitted to the rotating member 11 via the engaging part of each guide protrusion 16c and the guide groove 11f. Since it is transmitted, the operation member 16, the coil spring 17, and the rotation member 11 rotate integrally, and the rotary encoder 5 operates according to the rotation of the rotation member 11. This makes it possible to perform various command control according to the rotation direction and the amount of rotation of the operating member 16 based on the output signal of the rotary encoder 5, for example, to select a suspension suitable for the situation of the driving path, and the like. Since the drive body 13 is caught by the click groove 8a and peeled off during rotation of the rotating member 11, the detent is generated, and this detent can be fed back to the operator who operates the operating member 16.

When command control by the operating member 16 is not required, when the operator presses and operates the operating member 16 in the up position, each guide protrusion 16c descends along the guide groove 11f. , The operation member 16 is locked in the lowered position by the push lock mechanism described above. That is, as shown in FIG. 10, although the sliding end part 21a of the sliding pin 21 in the rising position of the operation member 16 is engaged with the upper part of the reciprocating combined path 15d of the heart-shaped cam groove 15, When the operation member 16 is pushed in against the elastic force of the coil spring 17, as shown by the dashed-dotted line in the figure, the sliding end portion 21a is the lower portion of the path 15b from the reciprocating furnace 15d. Go to. After the operator pushes the operation member 16 again and the sliding end portion 21a reaches the bottom end of the path 15b, the operator removes the pushing force and the operation member 16 returns to the return force of the coil spring 17. It is returned a little bit upward and the sliding end portion 21a hangs on the lock portion 15a of the heart-shaped cam groove 15 and stops. As a result, since the operation member 16 is locked at the lowered position, the upper surfaces of the operation member 16 and the plurality of operation knobs 7 provided in the vicinity thereof are substantially the same, thereby preventing unintended operation. The risk to the body in a collision accident etc. can be reduced. At this time, a large repulsion force is accumulated in the coil spring 17 in the direction of raising the operation member 16, and the sliding end portion 21a is stopped by the locking portion 15a by receiving the repulsive force of the coil spring 17. As a result, the lock holding force of the push lock mechanism is increased, and it can be prevented that the lock is unintentionally released by external vibration. In addition, since the pinion 26 meshing with the rack 14 rotates during the pressurizing operation of the operation member 16, the lowering operation of the operation member 16 is applied by the rotation damper 19. The movement of the member 16 may be quieted to give a sense of quality.

On the other hand, in the case of using the operation member 16 locked in the lowered position as described above, if the operator presses the operating member 16 in the lowered position against the elastic force of the coil spring 17 to the solid line of FIG. As shown, when the sliding end 21a of the sliding pin 21 moves away from the lock portion 15a and moves to the lower part of the return path 15c, where the pushing operation force is removed, the operation member 16 causes the coil spring 17 to be removed. ), The sliding end portion 21a moves from the return path 15c to the upper part of the reciprocating path 15d. At this time, the operation member 16 tries to ascend forcefully due to the elastic force of the coil spring 17 sufficiently accumulated, but in this case, the pinion 26 engaged with the rack 14 rotates, and the rotary damper 19 Since braking is applied to the ascending operation of the operation member 16, the movement of the operation member 16 is quieted, thereby providing a sense of quality. In addition, the rising position of the operation member 16 is defined by the abutment of the projection 16a and the stopper projection 9a. However, since the movement of the operation member 16 is slow even before the rising position, the projection 16a and the stopper. The collision sound of the projection 9a becomes very small, and this can also give a sense of quality.

In the above embodiment, among the heart-shaped cam grooves 15 and the pin holders 18, which are the constituent members of the push lock mechanism, the heart-shaped cam grooves 15 are attached to the rotating member 11 and the pin holders 18 are provided. Has been described in the case where it is installed in the operating member 16, but in contrast to this, the heart-shaped cam groove 15 is installed in the operating member 16 and the pin holder 18 is installed in the rotating member 11. It is also possible. The same applies to the rack 14 and the rotary damper 19 which are constituent members of the operation resistance imparting means. In contrast to the embodiment described above, the rack 14 is installed on the operating member 16 and the rotary damper 19 is provided. It is also possible to install the rotating member (11).

In the above embodiment, the case where the operating member 16 is used as the rotating operation member of the rotating member 11 has been described, but it is also possible to provide a push switch operated by the pressing operation of the operating member 16. It is possible.

Since the composite operation mechanism of the present invention operates the damper in accordance with the lifting operation of the operating member to brake the lifting operation of the operating member, the movement when the operating member is automatically returned to the lifted position becomes smooth. I can let you feel sense of quality to an operator.
