[0017] Reference Figure 1 , 2 As shown in Figure 4, an extra-large outdoor umbrella includes an umbrella rib assembly 100, a column 200, a lifting tube 300, a lifting drive member 400, and an axis connection assembly 600. The umbrella rib assembly 100 includes an umbrella plate 110, a long umbrella rib 120, a short umbrella rib 130, a sliding rod 140, and a lower umbrella plate 150. A plurality of long umbrella ribs 120 are hinged on the umbrella plate 110, and the plurality of long umbrella ribs 120 are radially arranged. One end of the short umbrella rib 130 is hinged to the sliding rod 140, and the sliding rod 140 is slidably mounted on the bottom of the long umbrella rib 120. The sliding rod 140 is arranged along the long umbrella rib 120 reciprocates in the length direction, and the other end of the short rib 130 is hinged on the lower umbrella plate 150; the column 200 is fixed to the ground, and the lower umbrella plate 150 is fixed on the column 200; the lifting tube 300 is installed in the column 200, and the upper end of the lifting tube 300 is fixed to the umbrella plate 110; the lifting drive member 400 is connected to the lifting tube 300 through the transmission assembly 500, and the lifting drive member 400 lifts the lifting tube 300 through the transmission assembly 500; the shaft connection assembly 600 is installed between the lifting drive member 400 and the transmission assembly 500.

[0018] During the unfolding of the umbrella, the lifting drive member 400 lowers the lifting tube 300 through the transmission assembly 500. During the process of the umbrella plate 110 descending with the lifting tube 300, the sliding rod 140 slides on the long ribs 120 toward the umbrella plate 110. When the umbrella plate 110 descends to a preset position, the short ribs 130 support the long ribs 120, so that the umbrella is unfolded to achieve the unfolding of a large-area umbrella. During the folding of the umbrella, the lifting drive member 400 lifts the lifting tube 300 through the transmission assembly 500. During the process of the umbrella plate 110 ascending with the lifting tube 300, the sliding rod 140 slides in the opposite direction on the long ribs 120, and slides away from the umbrella plate 110. When the umbrella plate 110 rises to a preset position, the short ribs 130 fold in the direction of the column 200 to complete the folding of the umbrella. The above structure can provide stable support and folding for a large-area umbrella surface.

[0019] During the lifting process, the lifting drive member 400 and the transmission assembly 500 are connected by the shaft connection assembly 600. Due to the heavy weight of the rib assembly 100 and the umbrella surface, the load on the lifting drive member 400 during the rotation of the transmission assembly 500 is very heavy. The shaft connection assembly 600 can be used to reduce the weight of the load on the lifting drive member 400 during the driving process.

[0020] Reference Figure 1 , 35. An inner sleeve 700 is provided in the column 200, and the lifting tube 300 is installed in the inner sleeve 700. An opening 310 is opened on the tube wall of the lifting tube 300, and an auxiliary pulley 800 is installed in the opening 310. The auxiliary pulley 800 is rotatably installed between two wheel axle seats 320, and the wheel axle seats 320 are fixed on the tube wall of the lifting tube 300; an auxiliary pulley 800 is installed between the two wheel axle seats 320, and when the auxiliary pulley 800 moves with the lifting tube 300, the auxiliary pulley 800 rolls on the tube wall of the inner sleeve 700; an auxiliary pulley 800 is installed on the tube wall of the lifting tube 300, and when the lifting tube 300 is lifted or lowered, the auxiliary pulley 800 rolls along the tube wall of the inner sleeve 700 to improve stability during the lifting process.

[0021] Reference Figure 2 , 3 The transmission assembly 500 includes a screw nut 510 and a screw 520. The screw nut 510 is fixed in the lifting tube 300.
