(41) By this structure, the outdoor umbrella is controlled to unfold automatically. In another embodiment, the present invention further discloses a lifting mechanism 30 by which the outdoor umbrella manually unfolds. Further, the first gear 321 is connected to a connecting shaft 35 and the connecting shaft 35 is connected to a crank 14 provided on the umbrella stem 13. When the crank 14 is rotated, the first gear 321 is driven to rotate, and the first gear 321 drives the second gear 322 to rotate, thus driving the screw assembly 33 to move up and down.

(42) Referring to FIG. 16, further, the environment monitoring mechanism 40 comprises a solar assembly 41 comprising a solar panel 411, a light sensor 412, a sunlight control panel 413 and a battery 414. The light sensor 412 is received on the solar panel 411, there may be multiple solar panels 411, and multiple light sensors 412 are arranged on the solar panels 411, so it is helpful to monitor sunlight from multiple directions and angles and the monitored data is more accurate. In this embodiment, four light sensors 412 are arranged on four directions (i.e. east, west, south and north) on a same horizontal plane of the solar panel, sunlight shines on the solar panel 411, and the light sensors 412 sense the light intensity. When there is an included angel between the direction of sunlight and the vertical direction of the solar panel, the light intensity sensed by the four light sensors 412 is different, and the presented digital and electric effect reflects difference in voltage. The sunlight control panel 413 collects voltage data, calculates an average deviation, transforms it into a level signal, and transmits the signal to the main controller 50 for processing. After the signal is processed by the main controller 50, an execution signal is transmitted to an electric device to adjust and control the outdoor umbrella.

(43) The solar panel 411 and the light sensors 412 are received in a middle shell 415, all connected to the sunlight control panel 413 and electrically connected to the battery 414, and the sunlight control panel 413 is electrically connected to the main controller 50 and configured to transform the collected solar energy into electric energy which is then stored in the battery 414 to drive the main controller 50 and other circuit devices to which power is to be supplied. The sunlight control panel 413 and the main controller 50 are all received within a lower shell 416, and the main controller 50 is connected to other circuits by leads. The middle shell 415 is fixed on the lower shell 416. An upper cover 417 is arranged above the middle shell 415, is of a glass structure, and is configured to protect the internal solar panel 411.

(44) Further, referring to FIG. 17, the environment monitoring mechanism 40 comprises a wind speed measurement device 42 comprising a wind measurement vane 421, a frequency identification module 422 and a wind speed sensing module 423. The wind measurement vane 421 is connected to the frequency identification module 422, and the frequency identification module 422 and the wind speed sensing module 423 are both electrically connected to the main controller 50 by leads and transfer the monitored wind speed information to adjust the angle of an umbrella cover.

(45) 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.

(46) 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.

(47) The embodiments are merely used for explaining the present invention, without introducing any limitations thereto. Modifications may be made by those skilled in the art to those embodiments without creative contribution if necessary upon reading the specification, and those modifications shall be protected by the patent law as long as they fall into the scope defined in the appended claims of the present invention.
