Abstract

The present invention relates to a door actuator having a dual output shaft for an air conditioner of a vehicle, which includes a modulated feedback sensor having a hollow and fit to one of two output shafts of an output gear through the hollow for recognizing and controlling a feedback output value without using a circuit board, thereby minimizing deterioration of quality caused by soldering, reducing the number of parts, and minimizing an operational error. The door actuator includes: upper and lower covers (100, 120) coupled with each other; a motor (140) mounted inside the coupled upper and lower covers; an output gear (160) connected to a driving gear (142) mounted on a shaft of the motor through an array of reduction gears (150), the output gear (160) having a pair of output shafts (162, 164) formed on both sides thereof and drawn out through the upper and lower covers; and a modulated feedback sensor (170) having a hollow (172) and fit to one of the output shafts for recognizing and controlling a feedback output value according to a rotation of the output gear.

Claims

1. A door actuator having a dual output shaft for an air conditioner of a vehicle comprising:

upper and lower covers coupled with each other;

a motor mounted inside the coupled upper and lower covers;

an output gear connected to a driving gear mounted on a shaft of the motor through an array of reduction gears, the output gear having a pair of output shafts formed on both sides thereof and drawn out through the upper and lower covers; and

a modulated feedback sensor having a hollow and fit to one of the output shafts for recognizing and controlling a feedback output value according to a rotation of the output gear.

2. A door actuator according to claim 1, wherein the upper output shaft is a female output shaft having a coupling hole and the lower output shaft is a male output shaft, and the feedback sensor is fit to the lower output shaft.

3. A door actuator according to claim 2, wherein the outer diameter of the lower output shaft is smaller than that of the upper output shaft.

4. A door actuator according to claim 1, wherein a connection terminal for arranging the lead wires drawn out from the feedback sensor therein is formed on side circumferences of the upper and lower covers.

5. A door actuator according to any one of claims 1 to 4, wherein a number of mounting brackets, which will be mounted on the air conditioner, are correspondently formed along the side circumferences of the upper and lower covers.
