At the same time, the control device 12 and the drive component A11 arranged on the frame 1 can realize the automatic opening / closing of the curtain wall body 2, so that the opening / closing of the photovoltaic glass curtain wall is simpler and more convenient.

[0048] It should be noted that the above-mentioned hinge is a cylindrical structure, and two circular holes are provided on the inner edge of the frame 1 corresponding to the positions of the two hinges. The curtain wall body 2 is hinged in the frame 1 through the cooperation of the two hinges and the two circular holes, so that the curtain wall body 2 can rotate freely around the rotation center of the hinge to realize the opening / closing of the photovoltaic glass curtain wall.

[0049] Optimally, the movable side of the curtain wall body 2 is provided with a limit assembly 21 for supporting the curtain wall body 2 to maintain an open state; wherein,

[0050] The action end of the limit assembly 21 is connected to the inner side wall of the opening and closing edge of the frame 1, and the limit assembly 21 is connected to the control device 12 by signal;

[0051] When the above-mentioned control device 12 controls the action of the driving component A11 and drives the curtain wall body 2 to rotate around the rotation center of the hinge to open the curtain wall body 2, the control device 12 will control the action end of the limit component 21 to extend and abut against the opening and closing edge of the frame 1 to support the curtain wall body 2, thereby avoiding the sudden closing of the curtain wall body 2 due to the failure of the driving component A11, thereby improving the safety of the photovoltaic glass curtain wall.

[0057] When the curtain wall body 2 is opened, the control device 12 controls the action end of the electric telescopic rod 211 to extend along the axial direction of the sleeve 212 and abut against the frame 1 to support the curtain wall body 2. The sleeve 212 can play a limiting role to limit the extension direction of the action end of the electric telescopic rod 211 to stably support the curtain wall body 2.

[0058] Preferably, an annular baffle is provided at the opening of the sleeve 212, and the inner diameter of the baffle matches the diameter of the action end of the electric telescopic rod 211. The diameter of the supporting circular plate 213 is larger than the inner diameter of the baffle, so that the supporting circular plate 213 cannot escape from the opening of the sleeve 212, so that the structure of the limiting assembly 21 is more stable.

[0059] More preferably, there are two limit assemblies 21 , and the two limit assemblies 21 are respectively arranged close to the two ends of the movable side of the curtain wall body 2 , so that the limit assemblies 21 can better support the curtain wall body 2 .

[0064] In the initial state, the linear motor 111 is in an extended state;

[0065] When the photovoltaic glass curtain wall needs to be opened, the linear motor 111 can be controlled to contract by the control device 12, and the linear motor 111 will pull the cable A112, so that the cable A112 drives the curtain wall body 2 to move, thereby realizing the opening of the photovoltaic glass curtain wall;

[0066] When the photovoltaic glass curtain wall needs to be closed, the control device 12 controls the linear motor 111 to extend again, and the linear motor 111 releases the cable A112, and the curtain wall body 2 covers the frame 1 under the action of gravity, thereby closing the photovoltaic glass curtain wall.

[0067] Optimally, the driving assembly A11 further comprises a second pulley 115, see Figure 2 ;in,

[0068] The second pulley 115 is rotatably arranged at the junction of the outer edge of the fixed side of the frame 1 and the inner side wall of the fixed side of the frame 1, and the movable end of the cable A112 passes through the guide roller 113, the second pulley 115 and the first pulley 114 in turn and is connected to the fixed plate 23 to prevent the cable A112 from scratching the junction of the outer edge of the fixed side of the frame 1 and the inner side wall of the fixed side of the frame 1, thereby effectively improving the service life of the drive component A11.

[0069] Embodiment 2:

[0070] As a further optimization of the above embodiment, the inner side wall of the fixed side of the curtain wall body 2 is provided with a sliding rod 22, see Figure 1 , Figure 3 and Figure 4 ;in,

When the curtain wall body 2 rotates, the relative position of the fixed side to the frame 1 will not change, so it is called the fixed side. The movable side of the curtain wall body 2 refers to the side parallel to the rotation axis of the hinge and away from the hinge. When the curtain wall body 2 rotates, the relative position of the movable side to the frame 1 will change, so it is called the movable side.

[0074] Optimally, the two ends of the slide bar 22 are respectively provided with a drive assembly B and a return spring 225, see Figure 3 and Figure 4 ;in,
