  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 is a cross-sectional view of a vehicle air-conditioning control apparatus 100 according to the present embodiment, FIG. 2 is a plan view, and FIG. 3 is a vertical cross-sectional view taken along the line AA in FIG.

  As shown in FIGS. 1, 2, and 3, four pull cable units 10a to 10d for operating four different air conditioning functions are arranged in the left-right direction. These units are, from the left, a unit 10a for switching the conditioned air outlet mode into the vehicle, a unit 10b for switching the conditioned air set temperature, and a unit 10c for switching the conditioned air flow rate. The unit 10d is configured to switch the intake ratio between the inside air circulation and the outside air introduction of the intake air, and is housed in the housing 64. Cables are routed from each unit, and end portions of the respective cables are connected to a blowout port mode switching door, an air mix door, a driving mechanism for switching the air volume, and an inside / outside air switching door (not shown). The door is opened or closed or the drive mechanism is operated by pulling a predetermined cable, and the operation state of the predetermined air conditioning function is switched.

  As shown in FIG. 1, each unit 10 a to 10 d has a substantially cylindrical driven clutch rotating body 12 that is rotatable about the axis and movable in the axial direction from the bottom to the top with the rotation axis direction as the vertical direction. And a substantially cylindrical clutch rotating body 14, which is rotatable about an axis and fixed in the axial direction, a hollow shaft 16, and a pulling cable assembly 18 are arranged coaxially. . Thus, by using the same resin parts and structures as the unit, the parts can be shared and standardized.

  A plate-like link 20 that is long in the left-right direction is arranged immediately below the four units 10a to 10d. The link 20 is connected to the function switching motor 24 via the speed reduction mechanism 22 at the right end thereof. When the function switching motor 24 is driven, the link 20 moves in the left-right direction, and any one of the protrusions 26a to 26d provided on the upper surface of the link 20 is the shaft of the driven clutch rotor 12 of one unit among the four units. The lower end 28 is contacted and pushed up to engage the clutch. In this way, one desired air conditioning function can be selected from a plurality of air conditioning functions. FIG. 1 shows a state in which the leftmost unit is selected. On the other hand, pulleys 30a to 30d are formed on the outer peripheral surfaces of the clutch rotators 14a to 14d located substantially at the center in the vertical direction of the units 10a to 10d, respectively, and between the pulleys 30a to 30d and the pulley 32 at the left end. An endless cog belt 34 is wound around. The left end pulley 32 is connected to a drive motor 38 via a speed reduction mechanism 36 above the pulley 32. When the drive motor 38 is driven, the cog belt 34 rotates to rotate all the clutch rotators 14 at the same time, but only the rotation of the clutch rotator 14 with the clutch engaged is connected to the driven clutch rotator 12. The cable 40 wound around the predetermined pulling cable assembly 18 by being transmitted to the hollow shaft 16 is wound up, and a predetermined door (not shown) of the air passage is opened and closed. In this way, the operating state of the selected air conditioning function is switched. In the following, reference numerals of members used in common in each unit will be expressed by omitting suffixes a to d unless otherwise specified. For example, the unit 10a includes the clutch rotor 14a, the unit 10b includes the clutch rotor 14b, the unit 10c includes the clutch rotor 14c, and the unit 10d includes the clutch rotor 14d. Reference numerals 14a to 14d denote the clutch rotor 14 unless otherwise specified.

  The driven clutch rotator 12 is used to transmit or block the rotation of the clutch rotator 14 to or from the hollow shaft 16 by engaging and disengaging the clutch rotator 14 and the hollow shaft 16 respectively. The driven clutch rotator 12 is a substantially cylindrical member that is rotatable about an axis and movable in the axial direction, and protrudes in the axial direction on the outer diameter side of the upper surface of the disk 42 constituting the bottom surface thereof. A plurality of engaging protrusions 44 are formed spaced apart in the circumferential direction. The engagement protrusions 44 are arranged so as to face a plurality of engagement holes 46 on the outer diameter side of the lower surface of the clutch rotating body 14 to be described later. When the driven clutch rotor 12 is displaced upward, a plurality of engagement protrusions 44 are fitted into a plurality of opposing engagement holes 46 so that the clutch is engaged. On the other hand, a cylinder 48 extending coaxially upward is provided on the inner diameter side of the upper surface of the disk 42, and the upper end thereof enters the large-diameter cylindrical cavity 50 of the clutch rotating body 14 and is hollow inside the cavity 50. It is abutted against the lower end 52 of the shaft 16. The upper end 54 of the cylinder 48 is opened, and axial irregularities are formed on the opening edge. The unevenness is arranged so as to face the unevenness formed at the opening edge of the lower end 52 of the hollow shaft 16. When the driven clutch rotating body 12 is displaced upward, the clutches are engaged by engaging both the protrusions and recesses. A coil spring 56 is provided on the outer periphery straddling the cylinder 48 and the lower end 52 of the hollow shaft 16. The coil spring 56 is sandwiched between the upper surface of the disk 42 and the lower surface of the flange 58 extending radially outward from slightly above the lower end 52 of the hollow shaft 16 so that the hollow shaft 16 and the driven clutch rotor 12 are mutually connected. Energize in the pulling direction. Here, since the hollow shaft 16 is fixed in the axial direction, the coil spring 56 biases the driven clutch rotating body 12 so as to press downward. A plurality of locking claws 60 are formed on the upper surface of the disk 42 on the outer diameter side from the cylinder 48 and on the inner diameter side from the engagement projection 44 so that the upper end is expanded toward the outer diameter side. The locking claw 60 comes into contact with the retaining piece 62 provided near the lower inner diameter from the outer peripheral edge of the cavity 50 on the lower surface of the clutch rotator 14 from above, so that the driven clutch rotator 12 moves downward. Movement is restricted. As a result, the driven-side clutch rotor 12 is prevented from falling off from the unit, and an urging force is applied to the coil spring 56. On the other hand, a hemispherically rounded shaft lower end 28 is formed at the rotational axis position on the lower surface side of the disk 42. When the projection of the link 20 comes into contact with the lower end 28 of the shaft, the driven clutch rotating body 12 is displaced upward.

  The clutch rotator 14 is used to transmit the rotation of the cog belt 34 by engaging the driven clutch rotator 12 with the clutch. The clutch rotating body 14 is a substantially cylindrical hollow member fixed to the housing 64 so as to be rotatable about an axis and not to move in the axial direction. A plurality of engagement holes 46 recessed in the axial direction are formed on the outer diameter side of the lower surface of the clutch rotating body 14 so as to be spaced apart in the circumferential direction. The engagement hole 46 is formed so as to face the engagement protrusion 44 of the outer diameter portion of the upper surface of the driven clutch rotating body 12. When the driven clutch rotating body 12 moves upward, the clutch is engaged by fitting the plurality of engaging protrusions 44 into the opposing engaging holes 46, and the rotation of the clutch rotating body 14 is driven. The information is transmitted to the clutch rotating body 12. On the other hand, a large-diameter cylindrical cavity 50 penetrating in the axial direction is formed at the rotational axis position of the clutch rotor 14, and an inner diameter side of the driven clutch rotor 12 is opened from the lower opening of the cavity 50. The lower end 52 of the hollow shaft 16 enters from the upper opening, and is arranged so that the ends of the hollow shaft 16 abut each other. The clutch rotator 14 is in contact with the driven clutch rotator 12 at the portion of the locking claw 60 and the retaining piece 62 and is in contact with the hollow shaft 16 at the outer peripheral surface of the flange 58. Even when the clutch is disengaged, the rotational motions of each other are not transmitted through these portions. On the other hand, a pulley 30 is formed on the outer peripheral surface of the clutch rotating body 14, and a cog belt wound between the pulleys 30 a to 30 d of the clutch rotating body 14 of the four units 10 a to 10 d and the pulley 32 at the left end. When 34 rotates, all the clutch rotators 14a to 14d rotate at the same time.

  The hollow shaft 16 is used for pulling the rotation of the clutch rotating body 14 to the pulling cable assembly 18 or blocking the clutch assembly 18 by engaging and disengaging the clutch with the driven clutch rotating body 12. The hollow shaft 16 is a substantially cylindrical hollow member fixed to the housing 64 so as to be rotatable about an axis and not to move in the axial direction, and the diameter thereof is the same as that of the cylinder 48 of the driven clutch rotating body 12. The diameter is configured. The pulling cable assembly 18 is fixed to the upper side of the disk constituting the cover surface of the hollow shaft 16, and the lower end 52 is opened to abut the upper end 54 of the cylinder 48 of the driven clutch rotating body 12. The edge of the opening of the lower end 52 is formed with unevenness in the axial direction. The unevenness is arranged to face the unevenness formed in the opening of the upper end 54 of the cylinder 48 of the driven clutch rotating body 12. When the driven-side clutch rotator 12 moves upward and engages with the clutch rotator 14, both the concaves and convexes engage with each other, and the clutch rotator 14 and the driven-side clutch rotator 12 are hollow. The shaft 16 can rotate as a unit. By doing so, the rotation of the clutch rotating body 14 can be transmitted to the pulling cable assembly 18. On the other hand, the hollow shaft 16 is provided with a rotary switch for detecting the winding amount of the cable 40, that is, the operating state of the air conditioning function. A disc-shaped slider piece 68 that protrudes slightly outward in the radial direction is fixed to the outer peripheral portion of the hollow shaft 16 that is substantially intermediate in the vertical direction. A plurality of movable contacts 70 are provided on the outer diameter side of the upper surface of the slider piece 68. Above the slider piece 68, a substantially disc-shaped substrate 72 fixed to the housing 64 is provided so as to penetrate the hollow shaft 16, and does not rotate with the hollow shaft 16. A plurality of fixed contacts 74 corresponding to the number of preset operating states of the air conditioning function are provided on the lower surface of the substrate 72 so as to be spaced apart in the circumferential direction, and are electrically connected to an amplifier (not shown) via an external output connector 88. Connected to. When the slider piece 68 rotates and slides on the substrate 72 by the rotation of the hollow shaft 16, the movable contact 70 contacts or separates from the predetermined fixed contact 74 to open and close the conduction between the predetermined fixed contacts. Such a rotary switch is used to detect the winding state of the cable 40 of the pulling cable assembly 18 (open / closed state of the open / close door) and grasp the operating state of the air conditioning function.

  The pull cable assembly 18 is a well-known substantially disk-shaped cable winding structure as shown in Patent Document 3, and is used to open and close a door (not shown) of an air passage. A pulley 76 that is press-fitted into the assembly 18 is coaxially fixed to the upper end of the hollow shaft 16 so that it can rotate about the axis and does not move in the axial direction. The main body is fixed to the housing 64 via a pedestal 78. The cable 40 is wound around and fixed to the groove of the pulley 76, and the end of the cable 40 is routed so as to be connected to the door of the air passage for operating the operation state of the air conditioning function. When the hollow shaft 16 rotates, the pulley 76 rotates to pull the cable 40, and opens and closes the door of the air passage, thereby switching the operation state of the air conditioning function. The assembly 18 is provided with a moderation portion as click means for positioning the rotational position of the cable 40. This moderation portion includes a moderation ball 80, a moderation spring 82, and a pedestal 78.

  The function switching motor 24 is a servo motor used as a drive source for switching the air conditioning function, and is arranged on the right side when viewed from the four units 10a to 10d. The output shaft of the function switching motor 24 is provided with a reduction mechanism 22 for reducing the rotation of the motor. The pinion gear 84 meshed below the speed reduction mechanism 22 meshes with a rack pinion 86 formed on the right side surface of the flat plate-like link 20 laid in the left-right direction below the four units. When the function switching motor 24 is driven, the link 20 linearly slides in the left-right direction via the speed reduction mechanism 22, the pinion gear 84, and the rack and pinion 86. As described above, the rotational movement of the function switching motor 24 is converted into the linear movement of the link 20 in the left-right direction. On the upper surface of the link 20, four protrusions 26a to 26d are formed in a substantially conical shape at intervals according to the arrangement of the four units in the left-right direction. Then, by moving the link 20 in the left-right direction by a predetermined amount, any one of the four protrusions 26 a to 26 d comes into contact with any one of the shaft lower ends 28 of the driven clutch rotating body 12. When the conical side surface of the projection 26 comes into contact with the hemispherical surface of the shaft lower end 28 at an angle of about 45 degrees with respect to the straight line in the left-right direction, the driven clutch rotor 12 starts to be pushed upward. When the link 20 moves a little further and the top of the projection 26 and the top of the shaft lower end 28 come into contact with each other in the axial direction, the driven-side clutch rotator 12 is fully displaced upward and is completely engaged with the clutch rotator 14. At the same time, the driven clutch rotating body 12 and the hollow shaft 16 are engaged. FIG. 1 shows a state in which the clutch of the left end unit 10a is engaged. In addition, a state in which the hemispherical surface of the shaft lower end 28b of the second unit 10b from the left end and the side surface of the projection 26b of the link 20 are in contact with each other at an angle of about 45 degrees with respect to the straight line in the left-right direction is shown.

  The drive motor 38 is a servo motor used as a drive source for switching the operation state of the air conditioning function, and is disposed on the left side when viewed from the four units 10a to 10d. A pulley 32 is connected to the output shaft of the drive motor 38 via a speed reduction mechanism 36 for reducing the rotation of the motor. An endless cog belt 34 is wound around the pulley 32 and pulleys 30a to 30d formed on the outer peripheral surfaces of the clutch rotating bodies 14a to 14d of the four units. When the drive motor 38 is driven, the cog belt 34 rotates through the pulley 32. As the cog belt 34 rotates, the clutch rotators 14a to 14d rotate all at once. The surface of the cog belt 34 that comes into contact with the pulleys 32, 30a to 30d is alternately formed with cog ridges and cog valleys along the rotation direction of the belt, and the cog belt 34 and the pulleys 32, 30a. ˜30d always rotates in conjunction with each other without slipping. Note that an amplifier (not shown) determines the required rotation angle of the drive motor 38 for obtaining the winding amount of the cable 40 necessary for switching to the operation state selected by the user, and the movable contact of the rotary switch provided on the hollow shaft 16. 70, based on the signal of the fixed contact 74, the drive is controlled so that the drive motor 38 rotates by this rotation angle.

  The operation of the above configuration will be described. First, the operation when the air conditioning function is selected will be described. When the function switching motor 24 is driven, the link 20 moves in the left-right direction via the speed reduction mechanism 22, the pinion gear 84, and the rack and pinion 86. One of the four projections 26a to 26d on the upper surface of the link 20 contacts the shaft lower end 28 of the driven clutch rotor 12 of one unit. The driven clutch rotator 12 is pushed upward, and a plurality of engagement protrusions 44 are fitted into the corresponding engagement holes 46 so that the driven clutch rotator 12 and the clutch rotator 14 are engaged and driven. The side clutch rotor 12 and the hollow shaft 16 are engaged. By doing so, one air conditioning function is selected.

  Next, the operation for switching the operation state in the selected air conditioning function will be described. When the drive motor 38 is driven, the cog belt 34 rotates through the speed reduction mechanism 36 and the pulley 32. The clutch rotating bodies 14a to 14d of all the units 10a to 10d are rotated through all the pulleys 30a to 30d. Only the rotation of the clutch rotator 14 of the unit corresponding to the selected air conditioning function, that is, the unit in which the clutch is engaged is transmitted to the driven clutch rotator 12 and further transmitted to the hollow shaft 16. Pulley 76 of pull cable assembly 18 rotates to wind up cable 40 and open and close a door (not shown) in the air passage. By doing so, the operation state in the selected air conditioning function is switched.

  A specific example of the above operation will be described by taking as an example a case where the outlet mode switching function is switched to the “FACE” mode. In the following description, it is assumed that the vehicle air-conditioning control apparatus 100 according to the present embodiment is housed on the back side of the instrument panel surface near the vehicle driver's seat, and further, on this panel surface, air conditioning for operating the apparatus. Assume that a controller is provided. First, the user slides a lever knob (not shown) of the air conditioning controller so as to select the air conditioning function “blowing port mode switching function”. Then, a switch signal corresponding to the selected position of the lever knob is sent to an amplifier (not shown) housed on the back of the panel, and the amplifier sends a drive signal to the function switching motor 24. The function switching motor 24 rotates by a predetermined amount in response to this signal, and the link 20 moves to engage the clutch of the unit related to the air conditioning function “blowing port mode switching function”. In this way, the air conditioning function “outlet mode switching function” is selected. Next, the user rotates a dial knob (not shown) in order to select the “FACE” mode. Then, a switch signal corresponding to the rotational position of the dial knob is sent to the amplifier, and the amplifier sends a drive signal to the drive motor 38. The pulley 76 of the pull cable assembly 18 of the unit related to the air-conditioning function “blowing port mode switching function” in which the drive motor 38 rotates by a predetermined amount in response to this signal and the cog belt 34 rotates to engage the clutch. Turning the. The cable 40 is pulled by a predetermined winding amount, the door of the air passage is opened and closed, and the conditioned air outlet is switched to the outlet corresponding to the “FACE” mode. In this way, the operation state of the air conditioning function “blow-out port mode switching function” can be switched to the “FACE” mode.

  In the above embodiment, instead of using the function switching motor 24, the link 20 may be manually moved using a member such as a lever knob that can be manually operated. Moreover, it is good also as a structure which rotates the cog belt 34 using members, such as a dial knob in which manual rotation operation is possible instead of using the drive motor 38. FIG. In this case, the moderation portions 80 and 82 of the pulling cable assembly 18 give a feeling of moderation informing the user's fingertip of the rotational position of the cable 40, so that the operational feeling can be improved. Further, instead of using the pinion gear 84 as a power transmission means to the link 20, a cam structure may be used. Further, instead of using the cog belt 34, the clutch rotators 14a to 14d may be rotated at the same time by using a gear train that meshes between the clutch rotators 14a to 14d or other power transmission belt members. Moreover, you may stabilize the attitude | position of the to-be-driven side clutch rotating body 12 at the time of pushing up upwards by forming the top part of protrusion 26a-26d of the upper surface of the link 20 in planar shape, respectively. Further, a sensor for detecting the movement position of the link 20 may be provided on the output shaft of the function switching motor 24, and a sensor for detecting the rotational position of the cog belt 34 may be provided on the output shaft of the drive motor 38. . In this case, each of the motors 24 and 38 may be driven based on a signal from each sensor and a signal corresponding to the operation state of the air conditioning function selected by the user.

  In addition to the above embodiment, the vehicle air conditioning control device according to the present invention can be applied to other devices and methods that require output from three or more types of actuators, and the number of actuators used is reduced. can do.
