In this embodiment, the frame end blade connection portion 11, the fan end blade connection portion 13, the frame end arm connection portion 14 and the fan end wall connection portion 15 are sleeves each having a through hole. The frame end blade connecting part 11 is hinged with the frame end arm connecting part 14 through a frame hinge shaft 16, and the fan end blade connecting part 13 is hinged with the fan end wall connecting part 15 through a fan hinge shaft 17. Referring to fig. 2, in this embodiment, the frame hinge shaft 16 and the fan hinge shaft 17 are each formed by an intermediate core shaft 18 and end core shafts 19 connected to both ends of the intermediate core shaft 18, and the intermediate core shaft 18 is connected to the end core shafts 19 through a fixing structure; the fixing structure comprises a circular through hole formed in the end core shaft 19, a screw hole formed in the end surface of the middle core shaft 18 opposite to the end core shaft 19, and a screw 20 passing through the circular through hole and matched with the screw hole to fix the end core shaft 19 and the middle core shaft 18 together. The frame end arm connection 14 and the fan end wall connection 15 have mating non-circular cross sections with the end mandrel 19. The frame end blade connecting part 11 and the fan end blade connecting part 13 are intermediate connecting sleeves as shown in fig. 1. The intermediate mandrel 18 is rotatably disposed in the intermediate shaft bore of the intermediate connection sleeve. A non-circular jogged structure for limiting the rotation of the end mandrel 19 and the middle mandrel 18 along the rotation axis of the hinge is arranged between the connecting ends of the two mandrels. The non-circular embedding structure comprises an embedding groove formed on the end face of the middle mandrel 18, which faces the end mandrel 19, with a non-circular section which is concave along the rotation axis, and an embedding plug which is arranged on one end of the end mandrel 19, which faces the middle mandrel 18, and is matched and embedded with the non-circular section of the embedding groove. A limiting mechanism of an open position and a closed position is also arranged between the intermediate connecting sleeve and the intermediate mandrel 18 at the frame end. Referring to fig. 3, the limiting mechanism includes a limiting protrusion 21 disposed on the central spindle 18, a limiting groove 22 disposed on an inner wall of the central spindle hole of the central connecting sleeve and along a rotation path of the limiting protrusion 21, the limiting groove 22 defines a rotation angle of the limiting protrusion 21, and an end wall at an end of the limiting groove 22 is a limiting stop capable of limiting the flange to rotate to a predetermined angle.
In this embodiment, the intermediate mandrel 18 is first placed into the intermediate shaft hole of the intermediate connecting sleeve during assembly. The frame end arm connection portion 14 and the fan end wall connection portion 15 are then placed together in cooperation with the rotational axis of the intermediate connection sleeve pair Ji Jiaolian as the frame end blade connection portion 11 and the fan end blade connection portion 13. And the end core shaft 19 passes through the end shaft holes serving as the through holes on the frame end arm connecting part 14 and the fan end wall connecting part 15, and the embedded plug on the end core shaft is correspondingly and fittingly connected with the embedded groove on the middle core shaft 18. And then the screw 20 is screwed with the fixing screw hole formed on the middle connecting part through the circular through hole on the end core shaft 19, and the end core shaft 19 and the middle core shaft 18 are fixed together, so that a hinge structure of the hinge is formed. The magnet is mounted on the frame end mounting blade 10 and the fan end mounting blade 12 corresponding to the frame end arm connecting portion 14 and the fan end wall connecting portion 15 by a mounting seat.
In the corner state that the door and window sash is completely closed as shown in fig. 4, the frame end damping device is in a failure state, that is, the frame hinge end 3 and the frame end magnetic attraction device 6 mounted on the frame end mounting blade 10 are spaced from each other; the fan damping device is in a damping state, namely the frame end magnetic attraction device 6 arranged on the fan end mounting blade 12 of the fan hinge piece 2 and the fan hinge end 4 are attracted with each other. When the door and window sash is opened, the door and window sash leaves the door and window frame under the action of external force, and the fan damping device is in a damping state, and the frame damping device is in a failure state, so the fan damping device has larger resistance compared with the frame damping device, the hinge arm 5 keeps relatively motionless with the fan-end mounting blade 12 of the fan-end hinge piece under the damping action of the frame-end magnetic device 6, the hinge arm 5 relatively rotates with the frame-end mounting blade 10 of the frame-end hinge piece, the frame-end magnetic device 6 mounted on the frame hinge piece 1 gradually approaches to the frame hinge end 3 along with the rotation of the door and window sash, and when the door and window sash rotates to 90 degrees, the frame-end magnetic device 6 is attached to the frame hinge end 3, at the moment, the frame damping device is in a damping state, and the frame damping device still is in a damping state under the action of the frame-end magnetic device 6. The locked angle state of the door and window sash is shown in fig. 5. When the door and window fan rotates, the frame end arm connecting part 14, the fan end wall connecting part 15 and the corresponding end core shaft 19 are provided with matched non-circular cross sections, the frame end arm connecting part 14, the fan end wall connecting part 15 and the end core shaft 19 cannot rotate relatively, and the middle connecting sleeve rotates around the middle core shaft 18. When the door and window fan is opened to 90 degrees, a limiting protrusion 21 arranged on the middle mandrel 18 in the limiting mechanism arranged at the frame end abuts against the limiting stop arranged at the end part of the limiting groove 22 on the inner wall of the middle connecting sleeve. When the door and window sash moves further from 90 degrees to 180 degrees under the further action of external force, the frame damping device is in a damping state at this time, and because the limiting protrusions 21 in the matched limiting mechanisms are abutted against the corresponding limiting stops, the middle connecting sleeve at the frame end cannot rotate further around the middle mandrel 18, so that the external force can only overcome the magnetic resistance of the frame damping device, the fan hinge end 4 of the hinge arm 5 is separated from the frame end magnetic attraction device 6, namely, the fan end magnetic attraction device 8 is in a failure state, the fan hinge piece 2 can rotate relatively easily relative to the fan hinge end 4 of the hinge arm 5 until the fan sash rotates 180 degrees relative to the door and window frame, and the completely opened corner state of the door and window sash is reached as shown in fig. 6. When the door and window fan rotates, the frame end arm connecting part 14 and the fan end wall connecting part 15 of the fan end and the end core shaft 19 are provided with matched non-circular cross sections, the frame end arm connecting part 14 and the fan end wall connecting part 15 and the end core shaft 19 cannot rotate relatively, and the middle connecting sleeve rotates around the middle core shaft 18.
In this embodiment, in the completely closed corner state of the door and window sash, as described above, from the state shown in fig. 6, since the frame damping device is in the damping state and the sash damping device is in the failure state, the frame damping device has a larger resistance than the sash damping device, the hinge arm 5 keeps not rotating relative to the door and window sash under the magnetic damping action of the hinge arm 5 and the frame end magnetic attraction device 6, the frame end magnetic attraction device 6 fixedly mounted on the sash hinge member 2 in the sash damping device moves towards the sash hinge end 4 of the hinge arm 5 along with the rotation of the door and window sash, and when the door and window sash rotates to 90 degrees in the closing direction, as shown in fig. 5, the frame end magnetic attraction device 6 is attached to the sash hinge end 4, and at this time, the sash damping device is in the damping state. The limiting protrusion 21 arranged on the middle mandrel 18 in the limiting mechanism arranged at the fan end is abutted against the limiting stop arranged at the end part of the limiting groove 22 on the inner wall of the middle connecting sleeve. The frame damping device is still in a damping state under the mutual attraction action of the frame end magnetic attraction device 6 and the frame hinge end 3 of the hinge arm 5. When the door and window sash moves further from 90 degrees to complete closing under the action of external force, although the frame damping device is still in a damping state, at the sash end, due to the limitation of the corresponding limiting mechanism, the intermediate connecting sleeve cannot rotate further around the intermediate mandrel 18, so that the door and window sash force can only overcome the magnetic resistance between the frame end magnetic attraction device 6 and the frame hinge end 3 in the frame damping device, so that the frame hinge end 3 made of ferromagnetic materials is separated from the frame end magnetic attraction device 6, that is, the frame end magnetic attraction device 6 is in a failure state, and the frame hinge piece 1 can rotate relatively easily relative to the frame hinge end 3 of the frame connecting arm until the rotation of the door and window sash relative to the door and window frame reaches the corner state that the door and window sash is completely closed as shown in fig. 4.
In an alternative embodiment, the frame end magnetic attraction device 6 is arranged on one side of the frame hinged end 3 opposite to the door and window frame, the frame end ferromagnetic mass part 7 is arranged on the frame end mounting blade 10, the frame end magnetic attraction device 6 is arranged on one side of the fan hinged end 4 opposite to the door and window frame, and the fan end ferromagnetic mass part 9 is arranged on one side of the fan end middle connecting part opposite to the hinge arm.
In addition, in the above embodiment, the magnet may be replaced by an electromagnet.
In general, the member provided with the ferromagnetic portion may be made of a ferromagnetic material as a whole. When the corresponding component is made of a non-ferromagnetic material, a specific embodiment thereof may be replaced by attaching a part of a ferromagnetic material to the component as the ferromagnetic portion.

The fan end friction resistance device is a friction pair formed by two friction surfaces respectively arranged on the fan hinge piece 2 and the fan hinge end 4. In this embodiment, the friction pairs are disposed on opposite end surfaces of the frame hinge 1 and the frame hinge end 3 around the hinge shaft rotation portion, both friction surfaces of the friction pairs have a rough structure, and the friction surfaces only occupy a part of the opposite end surfaces; and/or the friction pair is arranged on the opposite end surfaces of the fan hinge piece 2 and the fan hinge end 4 around the hinge shaft rotating part, both friction surfaces of the friction pair are provided with rough structures, and the friction surfaces only occupy part of the opposite end surfaces. In the damping state, the two friction surfaces of the friction pair are contacted with each other and generate a preset friction force, in the failure state, the two friction surfaces of the friction pair are separated, and the friction force of the contact of each friction surface and the contacted end surface is smaller than the preset friction force. In an alternative embodiment of the present embodiment, the friction pair of the frame end comprises a damping plate provided on the frame hinge 1 protruding towards the hinge arm 5 and a damping plate protruding from the frame hinge end 3 of the hinge arm 5 towards the frame hinge 1. When the frame hinge end 3 of the hinge arm 5 is close to the frame hinge member 1, respective friction surfaces on the two damping plates are combined to form a damping state, and when the frame hinge end 3 of the hinge arm 5 is separated from the frame hinge member 1, respective friction surfaces on the two damping plates are separated from each other to form a failure state. Also, the friction pair at the fan end can be of the same structure. In the damping pair formed by two damping plates in the embodiment, friction force generated by friction characteristics of the two opposite friction surfaces can be only utilized, and rough structures in the forms of embossing, tooth patterns, organic pads and the like can be arranged on one or two surfaces.
In the above embodiment, the action relationship between the frame end damping device and the fan end damping device in opening and closing the door and window sashes may be opposite, and the functions of the present application may be implemented.
