The present invention relates to the technical field of outdoor leisure and shading supplies and in particular to an intelligent outdoor umbrella.
An outdoor umbrella is a common shading supply in travel and leisure. It is simple to use and the umbrella cover folds and unfolds quickly and deftly. It offers a comfortable and cool space for people in outdoor activities. Since the stem is out of the umbrella, when the umbrella cover unfolds, the umbrella cover is high off the ground, the space below the umbrella cover is large, and the shading effect is great. Usually, for such an outdoor umbrella, a crank structure is arranged on the stem, and the rope is tightened or loosened by rotating the crank to control the umbrella cover to fold or unfold.
In an existing outdoor umbrella, the angle adjustment mechanism is simple and generally mechanical.

Further, referring to
With such a structure, the angle adjustment mechanism 20, the lifting mechanism 30 and the rotation mechanism 60 in the present invention can operate separately and can be controlled manually. For example, the umbrella frame 12 is controlled to fold and unfold by the crank 14, the position of the umbrella frame 12 is adjusted by adjusting the position of the lower connecting rod 23A, and the whole umbrella stem 13 is controlled to rotate by 360 degrees by the tray brake 634A. Each component operates separately according to the specific situation and requirement. Also, the components can be controlled separately or synchronously according to the external environment, under the monitoring of the environment monitoring mechanism 40 and by using an internal control program. For example, when the wind speed reaches a certain preset value, the umbrella frame 12 will not unfold; when the sunlight doesn't reach a preset value, the umbrella frame 12 will not unfold; and when the sunlight incomes from the east, the umbrella frame 12 is controlled to rotate to the east, thus better shading the sunlight. The umbrella frame 12 can perform shading by 360 degrees by the combined action of the angle adjustment mechanism 20 and the rotation mechanism 60, and the shading effect is great.
Further, in addition to the control ways described above, a wireless communication module (not shown) can be provided on the main controller 50. The wireless communication module wirelessly communicates with a remote client, for example, it is connected to a mobile phone, a tablet or a computer, and related environmental parameters and related action parameters received in the main controller 50 are received and monitored to better know the operation state of the outdoor umbrella in the current state. Meanwhile, the operation of each component of the outdoor umbrella can be remotely controlled by a remote control terminal. There is no need for manual operation and the outdoor umbrella is controlled intelligently. Therefore, one client can control multiple outdoor umbrellas and the operation is simple and convenient.
