Title
(EN) AUTOMATIC DOOR OPERATOR
(FR) DISPOSITIF D'ACTIONNEMENT DE PORTE AUTOMATIQUE
Abstract
(EN)
An automatic door operator is disclosed, including: an actuating unit configured to output torque; a lead screw having a first end connected to an output end of the actuating unit and a second end extending away from the output end; a lead screw nut screwed to the lead screw; a slider attached to the lead screw nut, the slider being provided with a rack portion extending in a direction parallel to an axial direction of the lead screw, and during a movement of the lead screw nut from a first extreme working position away from the first end of the lead screw to a second extreme working position close to the second end of the lead screw, a length of an overlap between the rack portion and the lead screw in the axial direction gradually increasing; a housing having a guide hole configured to be slidably engaged with the slider; and an output shaft mounted in a mounting hole disposed on the housing, the output shaft having a gear portion positioned in the guide hole and engaged with the rack portion. The automatic door operator is high in transmission efficiency, small in size and low in running noise.

L'invention concerne un dispositif d'actionnement de porte automatique, comprenant : une unité d'actionnement conçue pour délivrer un couple ; une vis-mère ayant une première extrémité reliée à une extrémité de sortie de l'unité d'actionnement et une seconde extrémité s'étendant à l'opposé de l'extrémité de sortie ; un écrou de vis-mère vissé sur la vis-mère ; un élément coulissant fixé à l'écrou de vis-mère, l'élément coulissant étant pourvu d'une partie de crémaillère s'étendant dans une direction parallèle à une direction axiale de la vis-mère, et pendant un mouvement de l'écrou de vis-mère d'une première position de travail extrême à l'opposé de la première extrémité de la vis-mère jusqu'à une seconde position de travail extrême proche de la seconde extrémité de la vis-mère, une longueur d'un chevauchement entre la partie de crémaillère et la vis-mère dans la direction axiale augmentant progressivement ; un boîtier ayant un trou de guidage conçu pour être en prise coulissante avec l'élément coulissant ; et un axe de sortie monté dans un trou de montage disposé sur le boîtier, l'axe de sortie ayant une partie d'engrenage positionnée dans le trou de guidage et en prise avec la partie de crémaillère. Le dispositif d'actionnement de porte automatique présente une efficacité de transmission élevée, une petite taille et un faible bruit de fonctionnement.
