Description

Technical Field

[0001] The utility model relates to the technical field of outdoor umbrellas, in particular to an outdoor parasol with an automatic lifting mechanism and an electric outdoor parasol. Background Art

[0002] The Roman umbrella, also known as a 360-degree rotating umbrella, is the most versatile outdoor parasol. It can rotate horizontally a full circle and vertically 90 degrees. Using a Roman umbrella for sun protection is the most creative and relaxing way to provide sun protection on the Chinese market. Compared to other umbrellas, Roman umbrellas offer better sun protection and are easier to operate.

[0003] A typical Roman umbrella consists of a vertical pole and a canopy assembly, which includes a center rod, cross rods, an upper and lower canopy tray, and the canopy. When folding the umbrella, the upper canopy tray remains at the same height, and the cross rods are folded by moving the lower canopy tray upward, thereby achieving the function of folding the umbrella. Currently, large sunshade umbrellas on the market have large canopies, and the ribs are close to the ground when folded. This makes it easy for the umbrella to hit the table and items on the table when opening and closing. If the umbrella rim is too high, it will not provide sufficient shade.

[0004] To this end, as disclosed in Publication No. CN109619782A, a Roman umbrella that facilitates canopy retraction comprises a canopy assembly and a pole assembly that are coupled together. The canopy assembly comprises a central rod, an upper umbrella plate, a lower umbrella plate, a set of first cross rods, and a set of second cross rods that are coupled together. The upper umbrella plate is hingedly connected to a first diagonal tie rod, the middle portion of the first diagonal tie rod is hingedly connected to the second diagonal tie rod, and the lower end of the first diagonal tie rod is hingedly connected to a sliding portion. The pole assembly comprises an outer pole, an inner telescopic rod, a traction device, and an elastic element. The present invention has a reasonable design and a compact structure. The structure of the present invention allows the upper umbrella plate to move upward during the umbrella retraction process, thereby raising the height of the entire canopy assembly, making it less likely to hit a table or items on the table beneath the umbrella. Furthermore, this structure eliminates the need to raise the umbrella edge, which prevents poor sunshade performance due to an excessively high umbrella edge.

[0005] In the above structure, the raising and lowering of the umbrella column requires the cooperation of the internal multi-stage pulley for sliding traction, which makes the overall structure relatively complicated. When opening and closing the umbrella, the user needs a large operating force, which affects the performance and the manufacturing cost is relatively high. Utility Model Content

In another embodiment, the umbrella stand 200 can be equipped with an umbrella rope to achieve opening and closing, and the position adjustment of the cantilever base 300 is used to adjust the tilt angle position of the umbrella stand 200.

[0057] In combination with the above, the opening and closing movement mechanism in this embodiment includes a central screw 800 and a telescopic sleeve assembly 700. The central screw 800 is a lead screw, wherein the telescopic sleeve assembly 700 is moved up and down along the lead screw.
