Smart retractable sunrooms with courtyard covers in Chengdu residential areas can improve the indoor lighting quality of the basement, save energy, enhance building aesthetics, reduce indoor temperature, flexibly adjust air quality, and adapt to indoor environmental needs in different seasons.

The mechanical calculation, verification, and design of the mobile sunroom are based on the once-in-50-year wind and snow level of the location. The frame of the mobile sunroom is made of 6-series aviation aluminum alloy, and all connection points are reinforced with thickened built-in steel connectors and constructed using seamless splicing technology to ensure a firm and stable structure; Explosion proof tempered double-layer laminated glass is used, and the installation of the glass is fully protected and sealed with automotive grade EPDM rubber strips. The invisible fastening process is adopted, and the outer layer is sealed with automotive specific structural adhesive. The nested fan adopts a maze structure for wind, sand, dust, and air resistance, and the opening and closing parts adopt a male and female dynamic sealing structure. The five layer waterproof technology ensures very reliable waterproof performance.
