Title:
DOOR DRIVING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/215875
Kind Code:
A1
Abstract:
The present invention relates to a door driving apparatus characterized by comprising: a power generation means for generating power to open and close a door; a fastening means installed on the door or on an upper portion of a door frame; and a curved guide link which has one end connected to the power generation means and in which an arced guide hole, to which the fastening means is inserted and coupled, is formed in the longitudinal direction of a curved surface. The power generation means is installed on the door frame, and the fastening means is installed on the door. When the curved guide link is driven by the power generation means to rotate, a connection point (point of action) between the curved guide link and the fastening means is changed to transmit force in the direction in which the door is pulled or pushed. Accordingly, when the curved guide link is driven by the power generation means to rotate, the position to which the connection point (point of action) between the curved guide link and the fastening means transmits force changes according to the direction in which the door is pulled or pushed, and thus, the opening/closing operation of the door can be smoothly performed. Moreover, the present invention has the effect of preventing overload of the power generation means, and thus significantly reducing failures and maintenance costs.
