A rib assembly for an outdoor umbrella is capable of being telescopically packed. The rib assembly includes a longer rib and a shorter rib. When the rib assembly needs to be disassembled for packing, the longer rib or/and the shorter rib is able to be superimposed and retracted along a length direction. A locking mechanism is disposed on the longer rib or/and the shorter rib. When the rib assembly needs to be extended completely, the longer rib or/and the shorter rib are locked by the locking mechanism.

An outdoor umbrella frame has a telescopic structure, and includes an umbrella pole, a pull rod assembly and a rib assembly. The pull rod assembly includes a first pull rod and a second pull rod. The rib assembly includes a longer rib and a shorter rib, the umbrella pole may be telescopic along a length direction, and one or more of the first pull rod, the second pull rod, the longer rib and the shorter rib may be telescopic along a length direction. When the outdoor umbrella frame is assembled, the umbrella pole, the first pull rod, the second pull rod, the longer rib and the shorter rib are all in an extended and fixed state. When the outdoor umbrella frame is disassembled for packing, any one or more of the umbrella pole, the first pull rod, the second pull rod, the longer rib and the shorter rib are in a retracted state.

An umbrella and a method for controlling the same are provided. The umbrella includes a canopy; a support assembly configured to support the canopy; a driving mechanism configured to drive the support assembly; a photographing assembly configured to take a photograph of user's head(s) and output the photograph of user's head(s); and a control assembly configured to acquire a user information according to outputted photograph of user's head(s), and to process the user information to generate an adjustment signal, and to control the driving mechanism according to the adjustment signal, so as to adjust a coverage of the canopy.
