Abstract

An electric umbrella has a column, a first driving assembly, a slider, an umbrella frame, a second driving assembly, a power source and a control module. The first driving assembly is arranged on the column. The umbrella frame connects to the column and the slider, and the second driving assembly is arranged on the umbrella frame. A power source is charged by solar energy, a control module connects to the first driving assembly, the second driving assembly and the power source, respectively. When the electric umbrella needs to be folded or unfolded and the angle of the electric umbrella needs to be adjusted, a motor operates to drive a rope winding wheel to rotate, and the rope winding wheel rotates to adjust a traction rope, thereby enabling the folding or unfolding of the umbrella and adjustment of the angle of the umbrella frame.

Claims (40)

1 . An electric umbrella, comprising:

A column having a top;

a first driving assembly;

a slider slidably disposed on the column;

an umbrella frame;

a second driving assembly;

a power source;

a control module; and

a traction rope having a first end and a second end;

wherein,

the umbrella frame comprises a first connecting rod having a first end and a second end, a second connecting rod, a plurality of long rods, a plurality of short rods, a long rod nest, a short rod nest, a large support rod and a central pipe connecting to either the long rod nest or the short rod nest;

the first end of the first connecting rod rotatably connects to the top of the column and the second end of the first connecting rod rotatably connects to the second connecting rod, the second connecting rod rotatably connects to the long rod nest, the first connecting rod, the slider and the large support rod, respectively;

the first driving assembly is disposed on the column to drive the slider movably along the column so as to adjust an inclination angle of the umbrella frame;

the first driving assembly comprises a first motor, a first driving gear, a first output shaft, a second output shaft, a first rope winding wheel, a second rope winding wheel, a first traction rope segment, a second traction rope segment, and a rope-guide pulley;

the first motor connects to the first rope winding wheel and the second rope winding wheel through the first driving gear, the first rope winding wheel connects to the slider via the first traction rope segment, the second rope winding wheel connects to the slider by the second traction rope segment via the rope-guide pulley, the slider rotatably connects to the second connecting rod;

the second driving assembly is an electric driver which is capable of winding the traction rope for unfolding or folding the umbrella frame, the second driving assembly is disposed on the short rod nest;

the first end of the traction rope connects to the second driving assembly and the second end of the traction rope passes through the central pipe and connects to the long rod nest.

2 . The electric umbrella of claim 1 , wherein the second driving assembly comprises a second motor having an output and a second driving gear having an input and an output, the output of the second motor connects to the input of the second driving gear, a winding wheel connects to the output of the second driving gears, the traction rope comprises a third traction rope segment, the third traction rope segment is winded on the winding wheel and an end of the third traction rope segment connects to the long rod nest of the umbrella frame.

3 . The electric umbrella of claim 1 , wherein the rope-guide pulley is mounted on a rope-guide pulley frame, the rope-guide pulley frame is movably mounted on a rope-guide pulley frame fixing plate fastened by a connecting pin having a limiting portion at one end of the connecting pin, the rope-guide pulley frame fixing plate is fixed inside the column, a spring is mounted on the connecting pin which is arranged below the rope-guide pulley frame, and is used for automatically tensioning the traction rope.

4 . The electric umbrella of claim 1 , wherein the control module comprises a control main board, and a control panel and/or a wireless control module;

the control main board connects to the control panel and/or the wireless control module, and the control main board connects to the first driving assembly and the second driving assembly, so as to control the first driving assembly and the second driving assembly step by step or simultaneously, thereby enabling step-by-step or simultaneous automatic unfolding/folding of the electric umbrella and automatic adjustment of a sun-shading angle of the electric umbrella.

5 . The electric umbrella of claim 1 , wherein the power source comprises a solar photovoltaic panel, a solar module having two ends and an energy storage battery;

the solar module is arranged between the solar photovoltaic panel and the energy storage battery, the solar module converts solar energy into electric energy to charge the energy storage battery, the energy storage battery may also be charged by the solar energy, or removed to be charged.

6 . An electric umbrella, comprising:

a column having a top;
