Title:
INTELLIGENT HOME AUTOMATIC DOOR
Document Type and Number:
WIPO Patent Application WO/2018/184451
Kind Code:
A1
Abstract:
An intelligent home automatic door comprises a moving door, a door frame, a signal emitting device, a signal receiving device and an anti-pinch device. The moving door is connected to the door frame. The signal emitting device is installed at the moving door. The signal receiving device and the anti-pinch device are installed at the door frame. The anti-pinch device comprises an anti-pinch electromagnetic bolt, a positioning electromagnetic bolt and a housing. The anti-pinch electromagnetic bolt comprises an anti-pinch bolt, an anti-pinch spring and an anti-pinch electromagnet. The positioning electromagnetic bolt comprises a bolt sleeve, a bolt, a positioning spring and a positioning electromagnet. The bolt is positioned opposite to a positioning hole of the anti-pinch bolt. When the moving door shuts abruptly, an inertia switch transmits a signal to the signal emitting device. The signal emitting device transmits the signal to the signal receiving device, such that the signal receiving device controls the anti-pinch bolt to stick out to prop against the moving door; meanwhile, a repulsive effect between an electromagnetic force of the anti-pinch electromagnet and a magnetic force of a stationary electromagnet prevents the moving door from being shut, thereby protecting a child from being injured by the moving door.
