  The drawing cable units 50 a to 50 d are provided for each air conditioning function in order to switch each operation state of the air conditioning function, are arranged in a line in the left-right direction, and are housed in a resinous housing 58. Each of the units 50a to 50d is composed of a plurality of members having a common shape. For example, as shown in FIG. 4, the unit 50b has a substantially cylindrical driven clutch rotating body 60, clutch rotating body 62, hollow shaft 64, and pulling cable assembly 66 that are coaxial from the bottom to the top. It is comprised so that it may be arrange | positioned. The other units 50b to 50d have the same structure as the unit 50a. In the following description, reference numerals of members included in each of the pull cable units 50a to 50d will be described using the reference numerals of the unit 50a unless otherwise specified.

  The driven-side clutch rotator 60 is rotatable with respect to the rotation axis and is movable in the axial direction. The driven clutch rotator 60 is disposed on the upper side, is rotatable about the axis, and is fixed to the clutch rotator 62 in the axial direction. It has a structure that can be engaged and disengaged by known clutch engaging means such as a clutch. That is, a plurality of trapezoidal engagement protrusions 68 protruding in the axial direction are provided on the outer diameter side of the upper surface of the driven clutch rotating body 60 so as to be spaced apart in the circumferential direction. On the other hand, on the outer diameter side of the lower surface of the clutch rotating body 62, a plurality of engagement holes 70 are provided spaced apart in the circumferential direction. When the driven-side clutch rotator 60 moves upward in the axial direction and the plurality of engaging protrusions 68 are fitted into the corresponding engaging holes 70, the driven-side clutch rotator 60 and the clutch rotator 62 become mechanical. Engaging.

  The hollow shaft 64 is a substantially cylindrical hollow body that is rotatable about an axis and fixed in the axial direction, and a pulling cable assembly 66 is fixed to an upper end thereof. On the other hand, the lower end portion 72 of the hollow shaft 64 is formed with an unevenness in the axial direction (in FIG. 3, for convenience, the hollow shaft of the unit 50b is given a reference numeral), and the axial direction that engages with the unevenness Are formed on the upper end portion 74 of the cylinder 73 projecting upward in the axial direction on the inner diameter side of the upper surface of the opposed driven clutch rotating body 60 (in FIG. 3, for convenience, the driven clutch rotating body of the unit 50b is formed). Are marked with a sign). The cylinder 73 has the same diameter as the hollow shaft 64, and the hollow shaft 64 and the driven-side clutch rotating body 60 are coupled by engaging both concaves and convexes. When the driven-side clutch rotator 60 moves upward and engages with the clutch rotator 62, both the concave and convex portions are also engaged, and the clutch rotator 62, the driven-side clutch rotator 60, and the hollow shaft 64 are integrated. Can be rotated. A coil spring 78 is sandwiched between the lower surface of the flange 76 extending radially outward from the lower side of the hollow shaft 64 and the upper surface of the driven-side clutch rotor 60 around the outer periphery of the cylinder 73. Is provided to bias the hollow shaft 64 and the driven clutch rotating body 60 in a direction to separate them from each other when the clutch is in an engaged state. When a later-described protrusion 94a or the like is disengaged from a later-described shaft lower end 96a or the like of the driven-side clutch rotor 60, the driven-side clutch rotor 60 is moved downward by the urging force of the coil spring 78, and the clutch is released. The shaft lower end 96a and the like are in contact with the upper surface of the link 44. Thus, the hollow shaft 64 has a structure in which engagement and disengagement with the driven clutch rotating body 60 is performed by known clutch engagement means such as a dog clutch, and the clutch is in an engaged state. Sometimes, the rotation of the clutch rotator 62 is transmitted to the pull cable assembly 66 via the driven clutch rotator 60. The hollow shaft 64 is in contact with the upper part of the inner peripheral surface of the clutch rotating body 62 at the outer peripheral surface of the lower flange 76. It does not rotate.

  The hollow shaft 64 is provided with a rotary switch for grasping the operating state of the air conditioning function. Specifically, a disk-like slider piece 80 that protrudes slightly outward in the radial direction is fixed to the substantially middle outer peripheral portion of the hollow shaft 64 in the vertical direction. A plurality of movable contacts 82 are provided on the outer diameter side. On the other hand, a disk-shaped substrate 84 fixed to the housing 58 is provided above the slider piece 80 so as to be penetrated by the hollow shaft 64, and the substrate 84 is not rotated together with the hollow shaft 64. . A plurality of fixed contacts 86 corresponding to the number of preset operating states of the air conditioning function are provided on the lower surface of the substrate 84 so as to be spaced apart from each other in the circumferential direction. The fixed contacts 86 are external output connectors shown in FIG. It is electrically connected to the amplifier 38 via 87 (not shown). When the slider piece 80 rotates and slides on the substrate 84 by the rotation of the hollow shaft 64, the movable contact 82 comes into contact with the fixed contact 86 corresponding to the position. By detecting the rotational position of the hollow shaft 64, that is, the winding state of the cable 88 of the pulling cable assembly 66 (opening / closing state of the opening / closing door) using such a rotary switch, the operational state of the air conditioning function is determined by the amplifier 38. It comes to grasp by the side.

  The pulling cable assembly 66 is a well-known cable winding structure. The pulling cable assembly 66 pulls the cable 88 by rotating a pulley 90 provided in the assembly 66 and is fixed to the end of the cable 88. The operation state in the air conditioning function is switched by opening and closing a door or the like (not shown) or rotating a shaft.

  The function switching motor 40 is disposed on the right side of the four units 50a to 50d, and a reduction mechanism 92 including a plurality of gears is provided on the output shaft thereof. The pinion gear 93 meshed with the speed reduction mechanism 92 meshes with a rack pinion (not shown) formed in the left-right direction of the right side portion of the horizontally long flat plate link 44 laid under the four units 50a to 50d. When the function switching motor 40 is driven, the link 44 slides in the left-right direction via the speed reduction mechanism 92. Four substantially conical projections 94a, 94b, 94c, and 94d are formed on the upper surface of the link 44 at a predetermined interval according to the arrangement of the four units 50a to 50d in the left-right direction. Then, by moving the link 44 by a predetermined amount in the left-right direction, one of the four protrusions 94a to 94d comes into contact with any one of the shaft lower ends 96a, 96b, 96c, 96d of the driven clutch rotating body. As a result, one driven clutch rotator is pushed upward to engage the clutch rotator, and the driven clutch rotator and the hollow shaft are engaged.

  The drive motor 42 is disposed on the left side of the four units 50 a to 50 d, and a pulley 98 is connected to the output shaft via a speed reduction mechanism 97. An endless cog belt 46 is wound around the pulley 98 and pulleys 99a, 99b, 99c, and 99d formed on the outer periphery of the clutch rotating body of the four units 50a to 50d. When the drive motor 42 is driven, the cog belt 46 is rotated via the pulley 98. As the cog belt 46 rotates, the pulleys 98 and 99a to 99d rotate.

  The operation of the above configuration will be described. When the lever knob 22a is set to the position of the desired air conditioning function, a signal is generated in the slide switch 52a. The amplifier 38 drives and controls the function switching motor 40 so that the function switching motor 40 rotates by a predetermined rotation amount based on this signal and the signal from the position sensor 54, and at the same time, the air conditioning selected for the display indicator 26. Lighting control is performed so that the function is displayed. When the function switching motor 40 is driven, the link 44 moves, and the protrusion corresponding to the selected air conditioning function comes into contact with the lower end of the shaft of the driven clutch rotor of the pulling cable unit corresponding to the selected air conditioning function. Then, the driven-side clutch rotator is pushed upward to engage the driven-side clutch rotator and the clutch rotator, and at the same time, the driven-side clutch rotator and the hollow shaft are engaged (in FIG. Is in a state). As a result, the pulling cable assembly of the pulling cable unit corresponding to the selected air conditioning function becomes operable.

  When the inner dial 21a is turned in this state, a signal corresponding to the rotational position is generated in the variable resistor 48a. Based on this signal, the signal from the rotation sensor 56, and the signal from the rotary switch of the unit corresponding to the selected air conditioning function, the amplifier 38 drives the drive motor 42 so that the drive motor 42 rotates by a predetermined angle. At the same time as the control, lighting control is performed so that the selected operation state is displayed on the display indicator 26. When the drive motor 42 is driven, the cog belt 46 is rotated, and only the rotation of the clutch rotator engaged with the clutch is transmitted to the driven clutch rotator, and the rotation of the driven clutch rotator is transmitted to the hollow shaft. . The pulley of the pull cable assembly rotates through the hollow shaft, and the cable is pulled by a predetermined amount based on the three signals. By opening and closing an open / close door (not shown) connected to the cable, the operating state of the selected air conditioning function is switched.

  In the above-described embodiment, for example, a driver who operates the air outlet mode switching function most frequently and then frequently operates the inside / outside air switching function sets the lever knob 22a in advance to the position of the mark 28a before traveling the vehicle. In addition, the lever knob 22b may be aligned with the mark 29b. By doing so, the clutches of the two units that are frequently operated can be engaged in advance, and the two air conditioning functions can be quickly operated to a desired operation state. If the user wants to switch the outlet mode to “FOOT” during traveling, he / she puts his / her finger on the inner dial 21a of the single dial knob 20 without visual confirmation and displays the indicator 26 near the driving line of sight. If the inner dial 21a is turned so that the “FOOT” display 30c is lit, one of the above units is operated to switch to the “FOOT” mode. Further, when it is desired to switch the inside / outside air mode to “inside air circulation” during traveling, a finger is put on the outer dial 21b of the single dial knob 20 without visual confirmation, and the display indicator 26 near the driving line of sight is displayed. If the outer dial 21b is turned so that the “inside air circulation” display 32b is turned on, the other one of the above units is operated to switch to the “inside air circulation” mode. By doing so, the operating states of the two air-conditioning functions that are frequently operated can be easily and accurately operated with priority over other functions, and safety during traveling is not impaired.

  In the above embodiment, when the lever knobs 22a and 22b are adapted to different functions, the projections 94a to 94d on the upper surface of the link 44 so that the inner dial 21a and the outer dial 21b can be easily operated. A plurality of sets of projections as shown above are also provided in the direction perpendicular to the paper surface of FIG. 3 on the upper surface of the link 44, and the link 44 is arranged in two directions, the left-right direction and the direction perpendicular to the paper surface of FIG. You may comprise so that sliding is possible. By doing so, the predetermined two protrusions on the upper surface of the link 44 can be pushed upward so as to contact the lower end of the shaft of the driven clutch rotating body of the predetermined two units. Further, when the lever knobs 22a and 22b are set to the same function, the amplifier 38 is operated so as to switch the operation state of one function regardless of which of the inner dial 21a and the outer dial 21b is turned. It is good also as a structure controlled by the side.

  In the above embodiment, a dial knob with a push function may be used instead of the inner dial 21a and the outer dial 21b. In this case, the dial knob can be pushed in the direction parallel to the rotation axis, and the operation state corresponding to the function selected by the lever knob 22a is changed by the rotation operation when the dial knob is not pushed, and the dial knob The operation state corresponding to the function selected by the lever knob 22b can be changed by the rotation operation at the time of pushing. The display indicator 26 may display an operation state switched by a dial knob rotation operation.

  In the above embodiment, instead of using the drive motor 42 as a drive source for rotating the cog belt 46, a configuration in which the rotation shafts of the inner dial 21a and the outer dial 21b are connected to the pulley 98 or the like as a drive source may be used. Good. Further, as a drive source for moving the link 44, instead of using the function switching motor 40, at least one fulcrum end of the lever knob 22a or 22b is mechanically connected to a clutch switching mechanism such as the link 44. Thus, a configuration in which the link 44 is directly moved by the sliding operation of the lever knob 22a or 22b may be used. By doing so, the number of motors can be reduced. Furthermore, as an operation member for switching the air conditioning function, an operation member having a form that can be distinguished from the dial knob 20 for switching the operation state may be used instead of using the lever knob 22a or 22b.
