Background

The sun shading of a building facade or a daylighting roof can be divided into three types according to the position of a sun shading system: external sunshade, middle sunshade and internal sunshade. The outer sunshade is positioned on the outdoor side of the building facade or the daylighting roof. The middle sunshade is positioned in the middle of the maintenance structure outside the building, for example, sunshade shutters are arranged in the middle air layer of the hollow glass. The inner sunshade is positioned at the indoor side. From the view of the sun-shading effect, under the condition of the same sun-shading area, the outer sun-shading effect is optimal, and the solar radiation can be shielded to the maximum extent. The prior art external sunshade usually uses a horizontal or vertical sunshade fixed plate structure, i.e. a flat plate-shaped or inclined plate-shaped sunshade 02 protruding outwards is arranged on the outer wall above the window 01, as shown in fig. 1a and 1b, or vertical sunshade 02 protruding outwards is arranged on both sides of the window 01, as shown in fig. 1c, and the material is metal section bar, metal plate or glass. The disadvantage of this awning is that the sun-shading effect is not good, and only when the sun's altitude is within a certain range will a better sun-shading effect be produced. In most cases, sunlight will also pass through the sun visor and directly irradiate the room. In addition, the sun shading device cannot be folded, and has no way of adjustment when the sun is absent in a cloudy day or the sun is expected to be irradiated, so that the use flexibility is poor.

In the prior art, an external sunshade structure is also provided, which is in the form of a liftable sunshade louver, and the plane of the louver is parallel to the external decorative surface of the building. When the sunlight is sufficient, the sun-shading blind falls down, and the sunlight can be effectively shielded; when lighting is required, the blind can be raised. Compared with the sun visor, the system has the advantages of ideal sun-shading effect and flexible use, but has the defects of poor wind pressure resistance, easy damage and unsuitability for being applied to the outer vertical surface of a middle-high building. The sun shading device is suitable for inner sun shading and middle sun shading. When the inner sunshade and the middle sunshade are used, a large amount of heat is absorbed by the sunshade curtain and is transferred indoors, and the heat-avoiding effect is poor.

In summary, there is no external sunshade device in the prior art which can give attention to both sunshade and lighting, is suitable for being arranged on middle and high-rise buildings, is not easy to damage and has long service life.
