The work process of the reversible glass curtain wall is as follows:

firstly, during windowing and air exchanging:

1. if the bottom edge fixing pin assembly 6a is not in the locking state, no obstacle exists in the room, and the handle 24 on the glass frame 3 is pushed by the outstretched hand, the window opening angle is adjusted according to the air exchange area required by the user as a common window is opened.

2. If the bottom edge fixing pin assembly 6a is in a locked state, the bottom edge unlocking pull wire 21a is pulled, the bottom edge pin 17a is retracted against the pre-tightening force of the bottom edge spring 18a, and then the handle 24 is pushed, so that the window can be opened.

Secondly, when the glass is cleaned:

the method for automatically turning over the glass in the electrified state comprises the following steps:

1. when the linear motor mover 4 is in any position between the off-state position sensor 14 and the on-state position sensor 15, the button 23 is clicked, and the linear motor mover 4 sends its own position signal on the linear motor stator track 8 to the controller MCU10 for storage. Then, the controller MCU10 sends a command to the linear motor mover 4, and the linear motor mover 4 moves to the position of the open position sensor 15, so that the movable glass 2 of the window meets the turning condition. If the linear motor mover 4 is in the position of the on-state position sensor 15, the above process is omitted. The controller MCU10 commands the side electromagnet in the side fixing pin assembly 6b to be electrified and generate a magnetic field, the side armature is attracted to overcome the pretightening force of the side spring, the side pin column retracts, and the side fixing pin assembly 6b is in an unlocking state at the moment. Then the controller MCU10 orders the rotary stepping motor 5 to drive the movable glass 2 to rotate 180 degrees, then the controller MCU10 orders the side electromagnet in the side fixing pin assembly 6b to power off and lose the magnetic field, the side spring restores to the original state and drives the side armature to move outwards, the side pin column extends out, and the side fixing pin assembly 6b is in a locking state. When the movable glass 2 approaches the final moment of turning, the side pin column in the side fixing pin assembly 6b slides into the side locking groove 11b through the side guiding inclined notch 22b, so that the movable glass 2 is locked. After the movable glass 2 is turned over and locked, the controller MCU10 commands the linear motor mover 4 to return to the initial position according to the stored position information of the linear motor mover 4.

2. When the linear motor mover 4 is in the position of the closed state position sensor 14, the window is in the closed state at this time. When the button 23 is clicked, the controller MCU10 first energizes the bottom electromagnet 19a in the bottom anchor pin assembly 6a and generates a magnetic field, which attracts the bottom armature 20a against the biasing force of the bottom spring 18a, and the bottom anchor pin 17a retracts from the bottom locking slot 11a, so that the bottom anchor pin assembly 6a is in an unlocked state. The controller MCU10 sends a pushing command to the pushing linear motor 25 to enable the pushing rod 26 to extend out of the glass frame 3, at the moment, the first connecting rod 16a, the second connecting rod 16b and the third connecting rod 16c are not collinear with the linear motor stator track 8 any more, and then the pushing linear motor 25 retracts to reset. The controller MCU10 continues to send commands to the linear motor mover 4, and the linear motor mover 4 moves to the position of the open position sensor 15, at which time the moving glass 2 of the window meets the flipping condition. The controller MCU10 commands the side electromagnet in the side fixing pin assembly 6b to be electrified and generate a magnetic field, the side armature is attracted to overcome the pretightening force of the side spring, the side pin column retracts, and the side fixing pin assembly 6b is in an unlocking state at the moment. Then the controller MCU10 orders the rotary stepping motor 5 to drive the movable glass 2 to rotate 180 degrees, then the controller MCU10 orders the side electromagnet in the side fixing pin assembly to power off and lose the magnetic field, the side spring restores to the original state and drives the side armature to move outwards, the side pin column extends out, and the side fixing pin assembly 6b is in a locking state. When the movable glass 2 approaches the final moment of turning, the side pin column in the side fixing pin assembly 6b slides into the side locking groove 11b through the side guiding inclined notch 22b, so that the movable glass 2 is locked. When the movable glass 2 is turned over and locked, the controller MCU10 sends a command to the linear motor mover 4, and the linear motor mover 4 returns to the position of the closed position sensor 14. In the process, the bottom side pin 17a of the bottom side fixing pin assembly 6a slides into the bottom side locking groove 11a through the bottom side guide inclined notch 22a, and the bottom side fixing pin assembly 6a is in the locking state, and finally the window is closed.

The method for manually turning the glass in the power-off state comprises the following steps:

1. when the linear motor mover 4 is located at any position between the closed state position sensor 14 and the open state position sensor 15, the handle 24 is manually pushed, so that the linear motor mover 4 reaches the position of the open state position sensor 15, and the movable glass 2 of the window meets the turning condition. If the linear motor mover 4 is in the position of the on-state position sensor 15, the above process is omitted. The side unlocking stay wire is pulled manually, the side armature is pulled up, the side spring is compressed, the side pin column retracts, and the side fixing pin assembly 6b is in an unlocking state. The movable glass 2 is manually pushed to rotate for a certain angle, and then the side unlocking pull wire is released. When the movable glass 2 rotates to 180 degrees, the side spring restores to the original state and drives the side armature to move outwards, the side pin column extends out, and the side fixing pin assembly 6b is in a locking state at the moment. When the movable glass 2 approaches the final moment of turning, the side pin column in the side fixing pin assembly 6b slides into the side locking groove 11b through the side guiding inclined notch 22b, so that the movable glass 2 is locked. After the movable glass 2 is turned over and locked, the handle 24 is pulled again, so that the linear motor rotor 4 moves to a proper position, and the window opening angle is adjusted according to the required ventilation area.

2. When the linear motor mover 4 is in the position of the closed state position sensor 14, the window is in the closed state at this time. The bottom side release wire 21a is manually pulled, the bottom side armature 20a is pulled up and the bottom side spring 18a is compressed to retract the bottom side pin 17a, and the bottom side fixing pin assembly 6a is in the unlocked state. The handle 24 is pushed manually, so that the linear motor mover 4 reaches the position of the open state position sensor 15, and the movable glass 2 of the window meets the turning condition. The side unlocking stay wire is pulled manually, the side armature is pulled up, the side spring is compressed, the side pin column retracts, and the side fixing pin assembly 6b is in an unlocking state. The movable glass 2 is manually pushed to rotate for a certain angle, and then the side unlocking pull wire is released. When the movable glass 2 rotates to 180 degrees, the side spring restores to the original state and drives the side armature to move outwards, the side pin column extends out, and the side fixing pin assembly 6b is in a locking state at the moment. When the movable glass 2 approaches the final moment of turning, the side pin column in the side fixing pin assembly 6b slides into the side locking groove 11b through the side guiding inclined notch 22b, so that the movable glass 2 is locked. When the movable glass 2 is turned over and locked, the handle 24 is pulled again, so that the linear motor rotor 4 moves to the position of the closed state position sensor 14. In the process, the bottom side pin 17a of the bottom side fixing pin assembly 6a slides into the bottom side locking groove 11a through the bottom side guide inclined notch 22a, and the bottom side fixing pin assembly 6a is in the locking state, and finally the window is closed.
