[0028] Refer to Figure 1 、 2 As shown in FIGS. 、 and 4, a super-large outdoor umbrella includes a rib assembly 100, a column 200, a lifting tube 300, a lifting driving member 400, and a shaft connection assembly 600. The rib assembly 100 includes an umbrella disk 110, long ribs 120, short ribs 130, a sliding rod 140, and a lower umbrella disk 150. A plurality of long ribs 120 are hinged to the umbrella disk 110, and the plurality of long ribs 120 are radially arranged. One end of the short rib 130 is hinged to the sliding rod 140. The sliding rod 140 is slidably mounted at the bottom of the long rib 120, and the sliding rod 140 reciprocates along the length direction of the long rib 120. The other end of the short rib 130 is hinged to the lower umbrella disk 150; the column 200 is fixed to the ground, and the lower umbrella disk 150 is fixedly sleeved on the column 200; the lifting tube 300 is inserted into the column 200, and the upper end of the lifting tube 300 is fixed to the umbrella disk 110; the lifting driving member 400 is connected to the lifting tube 300 through a transmission assembly 500, and the lifting driving member 400 lifts and lowers the lifting tube 300 through the transmission assembly 500; the shaft connection assembly 600 is mounted between the lifting driving member 400 and the transmission assembly 500.

[0029] During the process of the umbrella being unfolded, the lifting driving member 400 lowers the lifting tube 300 through the transmission assembly 500. During the process of the umbrella disk 110 descending with the lifting tube 300, the sliding rod 140 slides on the long rib 120 in the direction of the umbrella disk 110. When the umbrella disk 110 descends to a preset position, the short rib 130 forms a support for the long rib 120, so that the umbrella is unfolded to realize the unfolding of a large-area umbrella; and during the process of the umbrella being folded, the lifting driving member 400 raises the lifting tube 300 through the transmission assembly 500. During the process of the umbrella disk 110 rising with the lifting tube 300, the sliding rod 140 slides in the opposite direction on the long rib 120, in the direction away from the umbrella disk 110. When the umbrella disk 110 rises to a preset position, the short rib 130 folds towards the column 200 to complete the folding of the umbrella; through the above structure, stable support and folding can be provided for a large-area umbrella surface.

[0030] During the lifting process, the lifting drive member 400 is connected to the transmission assembly 500 through the shaft connection assembly 600. Due to the large weight of the umbrella rib assembly 100 and the umbrella surface, the load on the lifting drive member 400 is very large during the process of rotating the transmission assembly 500. The shaft connection assembly 600 can reduce the weight of the load on the lifting drive member 400 during the driving process.

[0031] Refer to Figure 1 、 3 、5, an inner sleeve 700 is provided inside the column 200. The lifting tube 300 is inserted into the inner sleeve 700. An opening 310 is formed on the wall of the lifting tube 300. An auxiliary pulley 800 is installed in the opening 310. The auxiliary pulley 800 is rotatably installed between two wheel axle seats 320. The wheel axle seats 320 are fixed to the wall of the lifting tube 300; an auxiliary pulley 800 is installed between the two wheel axle seats 320. When the auxiliary pulley 800 moves up and down with the lifting tube 300, the auxiliary pulley 800 rolls on the wall of the inner sleeve 700; the auxiliary pulley 800 is installed on the wall of the lifting tube 300. When the lifting tube 300 moves up and down, the auxiliary pulley 800 rolls along the wall of the inner sleeve 700 to improve the stability during the lifting process.

[0032] Refer to Figure 2 、 3 As shown in

[0033] Refer to Figure 2 、 3 The transmission assembly 500 includes a lead screw nut 510 and a lead screw 520. The lead screw nut 510 is fixed inside the lifting tube 300. The lead screw 520 is threadedly connected to the lead screw nut 510. The lead screw 520 is connected to the lifting drive member 400 through the shaft connection assembly 600.

[0034] It further includes a bearing seat 640. The bearing seat 640 is used to install the tapered bearing 620 and the plain bearing 630. The connecting shaft 610 passes through the bearing seat 640. The loads borne by the connecting shaft 610 are borne by the tapered bearing 620 and the plain bearing 630, reducing the load on the lifting drive member to ensure the stability of opening and closing.

[0035] Refer to Figure 6 As shown in

[0036] Refer to Figure 4As shown, for the convenience of installing the long umbrella ribs 120, a plurality of upper clamping seats 111 are fixed on the umbrella disk 110. The upper clamping seats 111 are fixed to the bottom of the umbrella disk 110, and one end of the long umbrella rib 120 is hinged to the upper clamping seat 111.

[0037] For the convenience of installing the short umbrella ribs 130, a plurality of lower clamping seats 151 are fixed on the lower umbrella disk 150. The lower clamping seats 151 are fixed to the lower umbrella disk 150, and one end of the short umbrella rib 130 is hinged to the lower clamping seat 151.
