[0060] A micro motor two 22 is embedded on the connecting frame of the rectangular frame two 12 close to the hydraulic folding rod 14, the micro motor two 22 is embedded on the connecting frame close to the cavity one 19, the output shaft of the micro motor two 22 penetrates into the cavity one 19 and is fixedly connected with a chain wheel two 23, the chain wheel two 23 is the same specification as the chain wheel one 29, and the chain wheel two 23 is drivingly connected with the chain, so that the blade 18 is driven to rotate by the micro motor two 22.

[0061] The rectangular frame one 3, the rectangular frame two 12 and any blade 18 are all provided with an inclination sensor, the inclination sensor is signal connected with a processor, and the inclination sensor is used to detect the horizontal inclination of the corresponding component, so as to determine the rotation angle of the corresponding component.

[0062] A silicon photodiode and a photoelectric detector are respectively embedded on the side of the bottom frame 1 facing the outdoor, the silicon photodiode and the photoelectric detector are signal connected with the processor, the silicon photodiode and the photoelectric detector are both prior art, the silicon photodiode is used to detect the radiation intensity of sunlight, and the photoelectric detector is used to detect the direct angle of sunlight;

[0063] The glass of the glass window 2 adopts electrochromic glass, the electrochromic glass is prior art, and the transparency of the glass can be changed by electric field, so as to adjust the radiation intensity of sunlight.

[0064] In this embodiment, the direct angle of sunlight is detected by the photoelectric detector, and the processor controls the micro motor one 15 to adjust the rotation angle of the adjusting assembly, so as to shield or avoid the direct light of the sun, wherein the rotation state of the adjusting assembly and the glass window 2 is as follows:

[0065] State one: asFigure 7 When the rectangular frame two 12 is at an angle B of 0° with the glass window 2, the vane 18 can fully block the light passing through the glass window 2 when the glass window 2 is in a closed state;

[0066] At this time, the micro motor one 15 drives the vane 18 to rotate, the micro motor two 22 is detected and driven through the tilt sensor on the vane 18, the rotation angle of the vane 18 is controlled through the chain transmission, so that the light entering the room through the gap of the vane 18, the gap of the vane 18 can be adjusted by the rotation angle of the vane 18, so as to adjust the angle of the entering light.

[0067] State two: as Figure 8 Because the angle A is 180°, the angle B is in the range of 0°-180°, when the rectangular frame two 12 is at an angle B of 0° with the glass window 2, the vane 18 cannot fully block the light passing through the glass window 2, so that the light passing through the glass window 2 is completely shot into the room from the area of the angle B, the rest of the light is shot into the room from the range of the angle C through the vane 18, and the angle of the light is controlled by the vane 18, C=A-B;

[0068] State three: as Figure 9 When the rectangular frame two 12 is at an angle B of 180° with the glass window 2, the vane 18 cannot fully block the light passing through the glass window 2, so that the light passing through the glass window 2 is completely shot into the room from the window frame, and the angle B is 180° at this time.

[0069] At the same time, the transparency of the glass window 2 is controlled according to the detection intensity of the silicon photodiode to the sunlight, so as to adjust the intensity of the sunlight entering the room.

[0070] When the glass window 2 is not in a closed state, the opening angle of the glass window 2 is adjusted according to actual needs;

[0071] The opening angle of the glass window 2 is controlled by the processor and is denoted as angle D;

[0072] State four: as Figure 10 When B=D, the vane 18 fully blocks the entering sunlight, and the angle of the light entering the room is adjusted by adjusting the rotation angle of the vane 18, wherein the light entering from the D angle range does not need to pass through the glass window 2, and the light entering from the E angle range needs to pass through the glass window 2, and the E angle is the angle between the glass window 2 and the top surface of the back frame 1 away from the window;

[0073] State five: as Figure 11When B < D, i.e. the rectangular frame two 12 rotates to the outdoor side, the light rays from the B angle range only need to pass through the leaf blade 18 to enter the indoor, and the angle of the light rays entering the indoor is adjusted by adjusting the rotation angle of the leaf blade 18;

[0074] The light rays from the F angle range directly enter the indoor without passing through the glass window 2 and the leaf blade 18, and the F angle is the included angle between the rectangular frame two 12 and the top surface of the bottom frame 1 close to the window frame one side;

[0075] The light rays from the E angle range need to pass through the glass window 2 and the leaf blade 18 to enter the indoor, and the angle of the light rays entering the indoor is adjusted by adjusting the rotation angle of the leaf blade 18.

[0076] State six: as Figure 12 When B = 0°, i.e. the rectangular frame two 12 rotates to the outdoor side and is parallel to the glass window 2, the leaf blade 18 cannot fully shield the light rays passing through the glass window 2, so that the light rays from the D angle range directly enter the indoor without passing through the glass window 2 and the leaf blade 18, and the light rays from the E angle range need to pass through the glass window 2 and the leaf blade 18 to enter the indoor, and the angle of the light rays entering the indoor is adjusted by adjusting the rotation angle of the leaf blade 18.

[0077] State seven: as Figure 13 When B > D, i.e. the rectangular frame two 12 rotates to the indoor side, the leaf blade 18 cannot fully shield the light rays passing through the glass window 2, so that the light rays from the F angle range directly enter the indoor after passing through the glass window 2, and the light rays from the D angle range need to pass through the leaf blade 18 to enter the indoor, and the angle of the light rays entering the indoor is adjusted by adjusting the rotation angle of the leaf blade 18.

[0078] State eight: as Figure 14 When it is necessary to exhaust smoke in the indoor, the glass window 2 is rotated to 90° outward by driving the motor 11, the rectangular frame two 12 is rotated outward to make B = 0°, and the leaf blade 18 is reset, so that the leaf blade 18 closes the inner frame opening of the rectangular frame two 12, and the exhaust smoke does not affect the glass window 2.

[0079] As Figure 15 In this embodiment, two glass windows 2 can be arranged in the same bottom frame 1, and the rotation axes of the two glass windows 2 are adjacent, so that the two glass windows 2 form two mutually opposite openings after being opened;

[0080] The same driving assembly and adjusting assembly are arranged on the two glass windows 2, and the included angle A = 90° at this time;

[0081] In this way, the adjustment angle of the two glass windows 2 and the corresponding adjustment assembly can be adjusted according to the wind direction and the sunlight irradiation angle.

[0082] In the embodiment two, the following structure is added on the basis of the embodiment one.

[0085] In this embodiment, according to the sunlight radiation intensity detected by the silicon photodiode, for the light not penetrating through the glass window 2 and entering the indoor, first, the rectangular frame two 12 is rotated to the state of being attached to the rectangular frame one 3, the electromagnetic sheet 27 is electrified, and then the rectangular frame two 12 is rotated to the required position, at this time, the electromagnetic sheet 27 is magnetically connected with the magnetic sheet 26, so as to pull out the sunshade film 25, thereby shading the light directly entering the indoor, and when shading is not needed, the sunshade film 25 is automatically retracted into the cavity two 24 according to the self-retracting characteristic.
