Abstract: An electrically-operated opening and closing structure of a solar-charged umbrella includes a rib assembly and an electrically-operated opening and closing mechanism. When the drive motor of the electrically-operated opening and closing mechanism is started, the screw rod is driven to rotate and the movable disk connected to the screw rod is driven to move up and down so that the movable end of the rib of the rib assembly is driven to slide on a guide rail of the movable disk, thereby changing the angle of the rib to be opened/closed for the umbrella to be opened/closed. The umbrella may be controlled remotely, automatically closed for protection against strong wind, and automatically opened for charging under sunlight.

Abstract: Disclosed is a center pole fixing structure, including a center pole and a base. The base is provided with a center hole. The center pole is inserted into the center hole to be fixed. An anti-disengagement fixing structure is formed between the center pole and the base, achieves fixing by relative rotation of the center pole and the base, and constrains movement of the center pole in an axial direction thereof. A stopper for constraining the rotation of the center pole is disposed between the center pole and the base. The stopper is a movable pin, and the movable pin is controlled to enter or exit, thereby locking or unlocking the relative rotation of the center pole and the base. According to the disclosure, the center pole and the base are convenient to mount and dismount, and the fixed structure is firm and stable.

Abstract: An outdoor center pole structure includes a segmented center pole, an electrical connector, a rotary mounting plate, and a base. A second locking member is provided at the distal end of the first segment connected to the base. A first locking member is provided at the distal end of the second segment away from the base. A screw rod locked to the first locking member is provided in the center pole. The electrical connector is a plug-in connector, including a first connecting end that is fixed and a second connecting end that is rotatably mounted through a rotary mounting plate. The first connecting end is located at the distal end or a recessed portion of the center pole, and the second connecting end is located at the other end accordingly. The screw rod cooperates with the first locking member to achieve a stable connection of the segmented center pole.
