[0002] Doors and windows are important components of architectural style, so their shape, size, proportion, arrangement, color, and shape have a great impact on the overall shape of the building. Modern glass doors and windows, in addition to being able to block wind and rain, must also achieve a certain effect. Traditional doors and windows require curtain rods and curtains to be installed on the wall for shading.

[0003] In order to allow light and sunshine into the building through windows, a large amount of solar radiation will enter the room in summer, increasing the indoor temperature and thus increasing the energy consumption of indoor air conditioning. Therefore, in order to reduce the energy consumption of the building, the building needs to be shaded. Especially for the hot areas in the south, the interior of the building with glass curtain walls will be more unbearable, and people indoors will feel particularly uncomfortable, so it is very important to shade the building.

[0004] In the prior art, when using external sunshade devices for doors and windows, there is a phenomenon that the devices provide shade but not ventilation, which causes indoor air to be blocked and affects the actual use effect. In addition, most of the external sunshade devices on the market are usually unable to be stored on cloudy days or when not in use. The entire set of equipment is fixed outside the doors and windows, which is quite inconvenient. Moreover, after long-term use, a lot of dust and impurities will accumulate on the surface of the external sunshade devices.

At the same time, the horizontal plate 95 will fully stretch the waterproof rain cloth 96 and lay it flat on the top of the window frame 1 to prevent sudden rain from entering the interior of the window, thereby playing a protective role. When the horizontal plate 95 slides toward the end away from the window frame 1, the ring 101 can stretch the traction rope 107 to disengage the traction rope 107 from the winding wheel 106, thereby pulling the winding wheel 106 and causing the winding wheel 106 to drive the transverse threaded rod 103 to rotate, while contracting the spring spring 104. The rotation of the transverse threaded rod 103 can drive the upper brush 105 to slide against the outer wall of the sunshade louver 4 on the upper frame 2. At the same time, the connecting rod 110 and the protrusion 109 can drive the lower brush 108 to slide against the outer wall of the sunshade louver 4 on the lower frame 3. 05 and the sliding of the lower brush 108 can clean the sunshade louver 4 and the photovoltaic panel 5 to prevent dust from remaining on the sunshade louver 4 and causing dust to enter the room. At the same time, it can prevent the photovoltaic panel 5 from being blocked by dust, thereby improving the lighting effect of the photovoltaic panel 5. When the position of the sun changes, the screw rod 114 is rotated by the knob 115. The rotation of the screw rod 114 can make the push block 112 slide on the inner wall of the telescopic groove 111, and at the same time, the push rod 113 can push the photovoltaic panel 5, thereby causing the photovoltaic panel 5 to rotate. The angle of the photovoltaic panel 5 can be adjusted according to the position of the sun, thereby further improving the lighting effect of the photovoltaic panel 5.
