[0002] Outdoor sun umbrellas, as a type of outdoor leisure equipment, are widely used in squares, beaches, parks, courtyards, and other recreational places, providing people with a comfortable space to cool off. Currently used outdoor sun umbrellas are generally divided into hanging umbrellas and center-pole umbrellas based on the location of the canopy. Hanging umbrellas, with their side-suspended structure, have a larger bottom area of ​​the canopy and offer better usability.

[0003] A typical hanging umbrella consists of a pole and an umbrella canopy assembly. The canopy assembly includes a center rod, cross rods, an upper umbrella plate, a lower umbrella plate, and the umbrella surface. When closing the umbrella, the upper umbrella plate remains at a constant height, and the cross rods are folded by moving the lower umbrella plate up, thus achieving the function of closing the umbrella. Currently, large sun umbrellas on the market have large canopies, and when closed, the umbrella ribs are close to the ground, making it easy to bump into tables and items on them when opening and closing the umbrella. If the canopy is too high, it will not provide adequate sun protection. Utility Model Content

[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0033] Combination Figures 1 to 14 As shown, this utility model discloses a novel opening and closing liftable outdoor sunshade umbrella, including an umbrella column 100, a cross umbrella pole assembly 300, and an umbrella frame 600. The umbrella frame 600 is a common umbrella frame in the prior art, including an upper umbrella plate 610, a lower umbrella plate 620, several long umbrella ribs 601, and several short umbrella ribs 602. The cross umbrella pole assembly 300 includes a first cross umbrella pole 310 and a second cross umbrella pole 320. One end of the first cross umbrella pole 310 is hinged to a movable base 200 in the umbrella column 100. The first cross umbrella pole 310 and the second cross umbrella pole 320 are hinged to each other. The first cross umbrella pole 310 and the second cross umbrella pole 320 in the cross umbrella pole group 300 are arranged in an "X" shape. The "X" change of the first cross umbrella pole 310 and the second cross umbrella pole 320 is realized by the up and down movement of the movable base 200, thereby completing the opening and closing of the umbrella frame 600.

[0034] Preferably, the umbrella column 100 includes a fixed umbrella column 101 and a lifting umbrella column 102. The fixed umbrella column 101 is provided with a movable slide groove 104. The movable base 200 can move up and down along the movable slide groove 104 via a drive mechanism 400, thereby opening and closing the umbrella frame 600. The drive mechanism 400 can also drive the lifting umbrella column 102 to raise and lower its height. When the umbrella frame 600 is in a retracted state to an open state, the drive mechanism 400 drives the movable base 200 to move upward along the movable slide groove 104, and the drive mechanism 400 drives the lifting umbrella column 102 to lower its height. When the umbrella frame 600 is in an open state to a retracted state, the drive mechanism 400 drives the movable base 200 to move upward along the movable slide groove 104. 04. The structure moves downwards, and the drive mechanism 400 drives the lifting umbrella column 102 to achieve a height increase. The overall structure is optimized by using the drive mechanism 400 to synchronously drive the movement of the moving base 200 and the lifting umbrella column 102. The lifting and lowering movements of the moving base 200 and the lifting umbrella column 102 are opposite, so that when the umbrella frame 600 is unfolded, the moving base 200 is in a high position and the lifting umbrella column 102 is in a low position, thus ensuring that the umbrella frame 600 is at a normal unfolding height after unfolding. When the umbrella frame 600 is closed, the moving base 200 is in a low position and the lifting umbrella column 102 is in a high position, thus ensuring that the umbrella frame 600 can be relatively raised after closing, avoiding bottom collisions.

[0035] In summary, the drive mechanism 400 includes an operating mechanism 410, a linkage 420, a roller assembly, and an umbrella column base 440.
