    Abstract: An automatic door operator and a drive mechanism thereof are disclosed. The drive mechanism of the automatic door includes a planetary reducer driven by an electric motor, and a drive shaft driven by a planetary reducer. The planetary reducer includes a housing and a planetary gear train mounted in the housing. The planetary gear train includes a final-stage planet carrier configured to output torque, and a center of the final-stage planet carrier is provided with a torque output hole. A first end of the drive shaft is detachably inserted in the torque output hole and is non-rotatably connected to the torque output hole, and a second end of the drive shaft extends out of the housing. The drive mechanism of the automatic door operator is advantageous to the miniaturization design of the automatic door operator.

    Abstract: A closing hinge device includes a fixed element, a movable element and a pair of counteracting elastic members. One of the movable element or fixed element includes a generally box-shaped hinge body with a pair of working chambers to slidably house the counteracting elastic members. The other of the movable element or fixed element includes a pivot having a cylindrical portion that includes a pair of substantially equal grooves angularly spaced at 180° and each having a helical portion, the grooves communicating with each other to define a single guide element passing through the cylindrical portion. The box-shaped hinge body includes elongated slots, a pin being inserted through the single guide element and through the elongated slots to slide therethrough, and the counteracting elastic members act on the pin to promote the automatic returning of the closing element from the open position to the closed position.
