Anti-pinch door without injuring children

Abstract

Disclosed is an anti-pinch door without injuring children. A door frame is provided with a controller, a fixed electromagnet and a human body inductive sensor, a movable door is provided with a moving electromagnet and a handle, an approach switch is arranged on the handle, when the movable door is closed due to heavy wind, if a child stands at the position of the door frame, the human body inductive sensor transmits a human body induction signal to the controller, the controller controls the fixed electromagnet and the moving electromagnet to generate electromagnetic repulsive force so that the fixed electromagnet and the moving electromagnet are repulsive mutually, and then the movable door is stopped from being closed fast so as to avoid injuring the child; and when the door is closed, a user can hold the handle by a hand and contacts with the approach switch, the approach switch transmits a door closing signal to the controller, the controller switches off power of the fixed electromagnet and power of the moving electromagnet, the electromagnetic repulsive force between the fixed electromagnet and the moving electromagnet disappears, and then the movable door can be closed via the handle.

Description

technical field [0001] The invention relates to an anti-pinch door, in particular to an anti-pinch door for children. Background technique [0002] At present, the interior doors used in buildings, especially the interior doors of high-rise buildings, often appear to be closed quickly when there is a strong wind, and the closing force is extremely large, and the interior doors are easy to pinch children or the elderly. Anti-pinch doors have become people's safety needs. content of the invention [0003] The object of the present invention is to provide a child-proof pinching door, which can prevent children or old people from being pinched when the door is quickly closed in strong wind. [0004] The technical scheme adopted in the present invention is: the anti-pinch door for children includes a door frame, a movable door and a hinge, the movable door is hinged with the door frame through the hinge, the door frame is equipped with a fixed electromagnet, the movable door i...
