Abstract
A sunshade assembly includes a housing having a top opening, a winding shaft mounted rotatably in the housing, a sunshade cloth wound around the winding shaft, a pull rod connected to one end of the sunshade cloth and disposed external to the top opening, and a guide unit including a tubular casing mounted below the housing, and a guide rod extending downward from the pull rod and slidable in the tubular casing. A buffer unit includes a driven member mounted to the guide rod, and a buffer mounted to the tubular casing. When the sunshade cloth is moved by the winding shaft to a wound position from a stretched position, the guide rod is moved downward along with the pull rod until the driven member contacts the buffer, thereby retarding a downward movement speed of the guide rod to reduce a winding speed of the sunshade cloth.
