When the drive motor 38 is driven, the cog belt 34 rotates through the speed reduction mechanism 36, the gear 33, and the like. The clutch rotating bodies 14a and 14b of the two units 10a and 10b are rotated via the pulleys 30a and 30b. 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 pulling cable assembly 16 or 18. Is done. The pulley 76 or 77 of the pull cable assembly 16 or 18 rotates to wind up the cable 40 or 41 to open and close a door (not shown) of 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. The outlet mode switching function is assumed to correspond to the operation of the first pulling cable assembly 16a. 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 10a related to the air conditioning function “blow-out port mode switching function” and the first pulling cable assembly 16a. The spline hole 45a and the gear 49a are engaged with each other. 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 drive motor 38 rotates a predetermined amount in response to this signal, the cog belt 34 rotates, and the clutch is engaged. Turn the pulley 76a. The cable 40a 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 assemblies 16 and 18 give a feeling of moderation to the user's fingertip to inform the rotation position of the cables 40 and 41, thereby improving the operational feeling. be able to. 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 and 14b may be rotated simultaneously by using a gear train that meshes between the clutch rotators 14a and 14b or other power transmission belt members. 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. Further, in the above embodiment, two pull cable assemblies are provided for one unit. However, even if three or more pull cable assemblies are provided for one unit, the present embodiment is not limited. The same effects as the invention can be achieved. In this case, the protrusion on the upper surface of the link may be formed as a plurality of stepped protrusions such as a three-stage type.

  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.
