Closing, turning on the power supply of the positioning electromagnet (20), positioning the electromagnet (20) against the positioning spring (19) to attract the lock bolt (18) to reset, so that the lock bolt (18) leaves the positioning hole (16); 18) After leaving the positioning hole (16), the normally open switch (26) of the time relay (24) is disconnected, the power supply of the anti-pinch electromagnet (15) is cut off, and the anti-pinch (13) is elastic at the anti-pinch spring (14). Under the action, the movable door (1) and the door frame (2) are in a state of being closed; at the same time, the electromagnetic field of the first coil (27) of the anti-pinch electromagnet (15) disappears, and the anti-pinch (13) loses its magnetism. The mutual repulsive force of the magnetic pole of the anti-pinch electromagnet (15) and the magnetic pole of the fixed magnet (40) is eliminated.
The method for using an intelligent automatic home door according to claim 1, characterized in that: when the movable door (1) is quickly closed, the outer end surface (41) of the fixed magnet (40) and the anti-pinch (13) are fixed. The angle between the left end surface (43) is continuously reduced, and the left end surface (43) of the anti-pinch (13) is continuously approached to the outer end surface (41) of the fixed magnet (40), and the magnetic pole and the fixed magnet of the anti-pinch electromagnet (15) are fixed. (40) The mutual repulsive force of the magnetic poles is increasing.
The method for using the intelligent automatic home door according to claim 2, characterized in that: when the anti-pinch (13) of the anti-pinch electromagnetic plug (10) moves, the anti-pinch plug of the anti-pinch electromagnetic plug (10) (13) The distance of the movement is equal to the distance from the axis of the positioning hole (16) to the axis of the locking bolt (18) of the positioning electromagnetic plug (11).
The method for using the intelligent automatic home door according to claim 2, characterized in that: when the first coil (27) of the anti-pinch electromagnet (15) is energized, the fixing bolt of the anti-pinch (13) (30) And the movable pin (31) generates an electromagnetic polarity having the same polarity as the outer end surface (41) of the fixed magnet (40), and the movable pin (31) is first brought close to the outer end surface (41) of the fixed magnet (40), and the activity is utilized. The mutual repulsive force between the electromagnetic force of the plug (31) and the magnetic force of the fixed magnet (40) overcomes the elastic force of the movable spring (32), drives the movable bolt (31) to move to the right, and utilizes the electromagnetic force and the fixed magnet of the movable bolt (31). The magnetic force of (40) and the spring force of the movable spring (32) slow down the closing speed of the movable door (1).
The method for using an intelligent automatic home door according to claim 4, characterized in that: when the movable pin (31) of the anti-pinch electromagnet (15) moves to the right, the first of the anti-pinch electromagnet (15) The coil (27) is energized, and the movable pin (31) generates the same magnetic pole as the magnetic pole of the fixed magnet (40). The magnetic pole of the movable plug (31) and the magnetic pole of the fixed magnet (40) generate mutually exclusive forces, hindering the movable door ( 1) Quickly shut down.
The method for using an intelligent automatic home door according to claim 1, characterized in that: after the movable door (1) is stopped, the first coil (27) of the anti-pinch electromagnet (15) is de-energized, and the movable plug ( 31) The magnetic force disappears, and the magnetic poles of the movable plug (31) and the magnetic poles of the fixed magnet (40) are mutually exclusive, and the movable door (1) is reset to the normal use state.
