Problems solved by technology

[0035] In addition, in Figure 45 In the shown control operation device having a cylindrical operation knob, an interlocking gear constituting a sun gear is provided on the operation knob, and an output gear and the like are provided between the planetary gear meshing with the interlocking gear and the gear lever. method, the scheme of adjusting the gear ratio, but because of the structure of the reduction gear using a plurality of gears, there are problems such as complicated structure
[0036] In addition, in the current automobile, due to the improvement of the function of the vehicle-mounted device, the relationship between the number of devices such as operation switches and navigation has increased, and the installation space for the control and operation device for the air conditioner has become narrow, and there are three operation devices arranged in parallel in the horizontal direction. Knobs are the type of device used to control the operating device, which is difficult to arrange
[0037] In addition, since the corresponding operating parts are scattered, it is difficult to perform fumbling operations, and the operability during operation is not good.
[0038] In addition, in the control operation device having a cylindrical operation knob, in terms of the relation of constituting the restriction mechanism by the small ball provided on the interlocking gear and the restriction recess provided in the base, due to the fact that the operation knob is easy to operate On the contrary, between the interlocking gear 42 and the connecting gears 44, 45, between the connecting gears 44, 45 and the output gear 46, the backlash (swing back) generated between the bevel gear 47a and the gear rod 48, produces an inter-gear The backlash of the control cable increases, the travel loss of the control cable, hysteresis, and the specified cable travel cannot be obtained
[0039] Furthermore, if the diameter of the cylinder of the operation knob is increased, the distance between the restricting parts will be enlarged, so there is a problem that the operating knob stops at an intermediate position between the positions determined by the restricting parts, and it is difficult to align the positions.

Embodiment Construction

[0132] Next, an embodiment implemented as a control operation device for a vehicle air conditioner will be described with reference to the drawings.

[0133] figure 1 , figure 2 , image 3 shows the first embodiment, figure 1 For the front view of the control operating unit, figure 2 is a sectional view of the control operating device, image 3 A simplified diagram of the main parts.

[0134] As shown in the figure, in this control operation device, the cylindrical operation knob 61 is a dial knob for temperature adjustment, and the operation knob 62 provided on the knob protrusion inside the cylindrical shape of the operation knob 61 is the air volume. Adjustment with dial knob.

[0135] That is, the operation knob 61 is rotated so that the indicator 61a is selectively aligned with the symbol 63a of the display unit 63T, and the temperature is adjusted.

[0136] In addition, the protrusion is pinched with the fingertips, and the operation knob 62 is rotated so that...

Abstract

The present invention aims to provide a dial control device having a maneuverability of a control knob improved by making this in cylindrical shape and downsized by disposing another control knob installed within the first-mentioned cylindrical control knob. A dial control device comprising: a cylindrical control knob, a sun gear rotating integrally with said control knob for transmission of a driving force from said control knob, a planet gear interlocking with said sun gear, an internal gear cooperating with said sun gear to guide said planet gear in a direction of its movement, and a control cable coupled to said planet gear so as to operate an external device, wherein said driving force generated by rotational operation of said control knob is transmitted via said sun gear, said planet gear and said control cable to the external device to control operation of said external device.

Description

technical field [0001] The present invention relates to a dial-type control operation device that transmits a driving force generated by rotating an operation knob to an external device via a control cable to control the operation of the external device. Background technique [0002] There are various dial-type control and operation devices, and as an example, a control and operation device for an air conditioner installed in an automobile or the like will be described. [0003] Figure 42 with Figure 43 Indicates the vehicle air-conditioning control and operating device disclosed by Japanese Patent Application Laid-Open No. 2003-267034, etc., Figure 42 is the front view of the device, Figure 43 A top view of the device. [0004] As shown in the figure, the operating knob 11 for adjusting the wind direction, the operating knob 12 for adjusting the air volume, and the operating knob 13 for adjusting the temperature are set on the operating panel 10 in a rotatable manner ...
