As for the external sunshade, only that part of the sunlight will reach the outer surface of the glass window directly. In general, bright indoor blinds can only block 17% of the solar radiation heat, while the outdoor horizontal sunshade with an elevation of 45 °south can block 68% of the solar radiation heat. The shading effect of the two is very different.

Its working principle is that the motor drives the drive shaft to run, and the tight wire sleeve on the drive shaft turns the circumferential motion into linear motion. The aluminum drive card connected with the drive line drives the driving side aluminum profile to move parallel on the curtain line through the word connection, and the driving edge aluminum profile pulls one end of the curtain slowly to unfold and fold, that is, after all is folded, the opening and closing limiter switch is triggered respectively, the motor stops, and the operation is over.
