[0002] With social progress and improved living standards, modern people advocate a healthy and comfortable lifestyle. As the most private and relaxing place, the home is something people want to decorate to make comfortable. As a decorative item, Venetian blinds have multiple functions, including electric control, making them convenient and aesthetically pleasing. They have been widely used. Unlike the soft texture of curtains, Venetian blinds are generally made of materials such as wood, glass, and aluminum alloy, which can resist the erosion of sunlight, wind, rain, and dust, and are easy to clean.

[0003] However, in the actual production process of louvers, it has been found that the width of the blades of motorized sunshade louvers is currently fixed and cannot be adjusted, and they are generally made of all-aluminum profiles. When different blade widths are required according to customer needs, multiple louver molds are often required. As a result, the production cost increases with the increase in the number of molds, which puts economic pressure on enterprises. Therefore, this application proposes a motorized sunshade louver and louver structure. Summary of the Invention

[0011] Preferably, the vane clamps are provided with a pair of first clamping plates, and the vane wrap angles are provided with a pair of second clamping plates, and the pair of second clamping plates are nested and clamped with the pair of first clamping plates.

[0012] An electric sunshade louver comprises louver blades, louver end plate arranged at both ends of the louver blades, and louver transmission shaft arranged on the louver end plate, and the louver blades are the above-mentioned louver structure.

[0013] Compared with the prior art, the present application has the following advantages:

[0014] The pair of vane wrap angles, the pair of vane clamps and the pair of louver panels form the louver blades, and the whole is nested and clamped by the second clamping plates and the first clamping plates, so that the structure is simple and easy to assemble and operate.
