[0002] Among automotive exterior parts, the panoramic sunroof is divided into two parts in the form of front and rear modules, and currently a set of sunshades are generally used to cover the front and rear modules. This takes a long time to open the sunshade, which brings inconvenience to users. At the same time, the sunshade fabric of the sunroof will collapse, resulting in a smaller area of ​​the existing sunroof.

[0003] The existing patent CN204427581U sunshade driving mechanism uses a driving motor to drive two transmission flexible shafts to move forward and backward. The transmission flexible shaft pulls the front sunshade to open while pushing the rear sunshade to open, so that the front and rear sunshades can be opened at the same time.

[0004] In the above-mentioned comparative document, the two transmission flexible shafts are driven to move forward and backward by a driving motor. Although this method can effectively link the two sunroof components, the disadvantages are also obvious.
