ABSTRACT:
A sunshade structure includes an upright rod, a drive motor, a drive shaft, a pulley, a slide, a skeleton, a lift cord, and a control device. In practice, the control switch of the control device is pushed to start the drive motor to operate the sunshade structure, so that the sunshade structure is expanded or collapsed automatically in a wire manner. Alternatively, the wireless receiver of the control device receives a signal from a remote controller to start the drive motor to operate the sunshade structure, so that the sunshade structure is expanded or collapsed automatically in a wireless manner. Thus, the sunshade structure is expanded or collapsed automatically without needing a manual work, thereby saving the user's energy.
