The machine foot 6 is located the below of davit 9, and the central disk 10 is connected with power battery system 5's box fixed, and the dismantled and assembled battery module of installation in power battery system 5's the box, the screw 4 of propeller system can be protected to the machine foot 6, and the davit 9 is connected umbrella rope and organism simultaneously, can bear the weight of electrically driven power umbrella power device and the person of controlling in the flight. Preferably, the machine foot 6 is hinged with the central disc 10, the suspension arm 9 is hinged with the box body of the power battery system 5 and can be folded together with the support arm 3, in one embodiment of the invention, when the machine foot is hinged, a bolt is installed on the box body of the power battery system 5, the suspension arm 9 is provided with a light hole, and the light hole is sleeved on the bolt and can be in running fit with the bolt, so that the rotation (folding) of the suspension arm 9 is realized; when the machine leg 6 is connected with the central disc 10 through the second spring hinge in a hinged mode, the structure of the second spring hinge is the same as that of the first spring hinge 8, and when the machine leg 6 is connected with the second spring hinge, the connecting body of the machine leg 6 and the second spring hinge is connected in a welded mode.

Further, as shown in fig. 1 to 6, in the implementation, the central disc 10, the umbrella rope guide frame 2, the machine leg 6 and the suspension arm 9 are preferably made of aluminum alloy; the support arm 3, the protective frame 1 and the propeller 4 are preferably made of carbon fiber reinforced composite materials.

Meanwhile, the invention also provides an electrically-driven power umbrella, which comprises an umbrella rope, an umbrella body and an electrically-driven power umbrella power device, wherein the umbrella body and the electrically-driven power umbrella power device are respectively connected with two ends of the umbrella rope. The electric driving power umbrella uses the power device of the electric driving power umbrella as the propelling power, and has the characteristics of small vibration, small noise, small emission pollution and convenient operation compared with the internal combustion engine power umbrella.

Furthermore, in an embodiment of the present invention, the upper surface of the umbrella body may be covered with a flexible photovoltaic film plate, the flexible photovoltaic film plate is connected to the power battery system 5 through a wire, one end of the wire is connected to the flexible photovoltaic film plate and extends downward along the umbrella rope, and the other end of the wire is connected to the battery module, so that the power battery system 5 can be charged by using solar energy, and energy consumption is reduced.

In conclusion, the invention has the advantages and beneficial effects that:

compared with the prior art, the invention adopts an electric driving mode as power, and can solve the problems of high noise, large vibration and environmental pollution of the power umbrella of the existing internal combustion engine; meanwhile, the shape of the support arm 3 of the machine body is designed, the pneumatic wing shape of the support arm 3 is utilized to generate moment to offset or partially offset the reverse moment of the propeller system to the machine body, and the control performance of the electrically-driven power umbrella can be improved.
