An actuator for an automotive air conditioning damper that allows fine adjustment of the amount of warmth and ventilation.

In general, an air conditioning module is installed between an instrument panel of an automobile and an engine room to provide air and air to ventilate the room while supplying cool air and warm air to the vehicle interior through the ventilator of the instrument panel. The air conditioning module is provided with a device for generating cold and warm air, respectively, and a plurality of dampers for selectively supplying the cold and warm air generated from the devices and the air introduced from the outside to the room. .

Conventionally, an actuator for operating a damper in an air conditioning module has been operated to a desired position by contact of a contact slide with a printed circuit board on which an operation trajectory is drawn to control the position of the damper.

However, the conventional actuator as described above must be provided with a printed circuit board and a contact slide drawn with the operation trajectory in order to operate the damper, so that the production cost increases due to the increase in the number of assembly parts and the increase in the number of assembly operations. there was.

The present invention has been made in consideration of the above circumstances, and its purpose is to enable the adjustment of the opening and closing position angles of the dampers and the opening and closing stop positions to adjust the amount of cold and warm air and ventilation supplied into the cabin. And an actuator for a vehicle air conditioning damper that enables fine adjustment of the amount of warmth and ventilation.

The present invention is the motor gear and the reduction gear group of the motor and the output gear hinged to the damper to achieve the above object is coupled to each other gears to open and close the damper while the output gear is forward and reverse rotation by the forward and reverse rotation of the motor. In the actuator, a cam which is an insulator is formed on the bottom surface of the output gear, and a main plate switch electrically connected to the motor is installed in the housing in a ring shape to be electrically connected to the motor and the main plate switch. The present invention provides an actuator for automobile air conditioning damper, which is provided with first and second plate members which are conductors contacted or short-circuited by the cam.

1 to 3 show an actuator for a vehicle air conditioning damper according to the present invention, the actuator for a vehicle air conditioning damper is a rectangular cylinder housing 10 and a motor mounted inside the housing 10. (12), a group of reduction gears (16, 18, 20) and an output gear (22) for operating a damper (not shown) in the air conditioning module and a plate switch (conductor) electrically connected to the motor (12) ( 26, 28, 30 and the cam 24, which is an insulator formed integrally with the output gear 22.

The housing 10 is formed of a rectangular cylindrical body, the motor 12 is firmly mounted side by side on the inner side of the housing 10, the motor gear of the worm (worm) on the shaft of the motor 12 (14) is built up.

The reduction gear (16, 18, 20) group is a first reduction gear (16) which is a worm wheel (worm wheel) in gear coupling with the motor gear 14 and the third gear coupling with the output gear (22) It consists of a reduction gear 20 and a second reduction gear 18 geared between the first and third reduction gears 16, 20. The reduction gears 16, 18, and 20 are axially coupled side by side to the bottom surface of the housing 10.

On the bottom of the output gear 22, a cam 24, which is a non-conductor, is formed to protrude, and a main plate switch 26, which is a conductor in a ring shape, is installed in the housing 10, and the main plate switch 26 is the motor. It is electrically connected with (12).

The first plate switch 28 and the second plate switch 30 are conductors, one end of which is hinged to the bottom surface of the housing 10, and one end of which is interviewed with the main plate switch 26. It is electrically connected with the motor 12.

The present invention, which is configured as shown in FIG. 4, applies power to the wires 1 and 2 as shown in FIG. 4 to operate the motor 12 and the motor gear 14, the reduction gears 16, 18, and 20, and the output gear 22. Is rotated in conjunction with the power source, when the cam 24 formed on the bottom of the output gear 22 is located between the first plate switch 28 to which the power is applied and the main plate switch 26 to perform the ground function. This short circuit causes the operation of the motor 12 to stop. When power is applied to the wirings 1 and 3, the motor 12 is operated and the output gear 22 until the cam 24 is positioned between the main plate switch 26 and the second plate switch 30. ) Rotates to control the position of the damper. It is possible to adjust the stop position angle and the stop position number of the damper by changing the position of the plate switch 28 and 30 and increasing or decreasing the quantity.

In addition, as shown in FIG. 5, when the power source is applied to the wiring 4 and the opposite power source to the wiring 5, the motor 12 is operated and the motor gear 14, the reduction gear 16, 18, and 20 group and the output gear 22. ) Is rotated in conjunction with, the cam 24 formed on the bottom of the output gear 22 is positioned between the second plate switch 30 to which the power is applied and the main plate switch 26 performing the ground function. If the power is shorted to stop the operation of the motor (12). When the power source is applied to the wiring 5 and the opposite power supply to the wiring 4, the motor 12 operates in the opposite direction, so that the cam 24 is positioned between the main plate switch 26 and the second plate switch 30. Until the output gear 22 is rotated until it is to control the position of the damper. It is possible to adjust the stop position angle of the damper by changing the position of the main plate switch 26 (during bidirectional rotation operation).

Therefore, the stop position angle and the number of stop positions of the damper can be adjusted by changing the position and quantity of the plate switches 28 and 30, and the stop position angle of the damper can be adjusted by changing the position of the main plate switch 26. It is.

As described above, according to the present invention, a non-conductive cam is formed on the bottom of the output gear for opening and closing the damper, and a main plate switch which is a conductor is installed in the housing, and the main plate switch is contacted with the cam. By providing the first and second plate switches for shorting and stopping the driving of the motor, there is an effect that the opening and closing operation of the damper can be finely and accurately adjusted.
