Abstract
An electrical stand poling umbrella comprises a stand pole, a sliding seat, a suspending arm, a pulling arm, a frame and a drive mechanism. The frame includes a fixed joint mounted at a top of a central rod, a movable joint mounted at a bottom of the central rod, and multiple upper ribs and lower ribs. The drive mechanism includes an electromotor, a rope axle linked to the electromotor by a gear assembly, and a rope having a first end fastened on the rope axle. The drive mechanism is installed in the movable joint. The rope has a second end extending in turn through the frame, the suspending arm, and the pulley and is fastened on the stand pole. The electromotor is electrically connected with a power supply by a wire. The drive mechanism will not be dampened in rainy days. The stand pole has an enough strength for long usage life. In addition, the electromotor has a lower output power and is highly efficient. A hand crank is provided on the stand pole for manual operation.
