DETAILED DESCRIPTION

[0050] With reference to the drawings and embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0051] The purpose of the present application is to provide a sunshade umbrella integrated with photovoltaic panels to solve the problems existing in the prior art and improve the power generation capacity of the sunshade umbrella.

[0052] To make the above-mentioned purposes, features and advantages of the present application more apparent, clear and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments. The dashed lines in the drawings represent the upper convex folds 11 formed by the supporting ribs.

[0053] Referring to FIGS. 1-28, the present embodiment provides a sunshade umbrella 100 integrated with photovoltaic panels, which includes supporting ribs, a canopy 1, photovoltaic panels and a power supply circuit 3. The supporting ribs support the canopy 1 from the lower side, and the photovoltaic panels are fixed to the upper surface of the canopy 1. The power supply circuit 3 is connected to multiple photovoltaic panels and is configured to output electrical energy externally.

[0054] The number of photovoltaic panels is multiple, and the multiple photovoltaic panels are distributed circumferentially around the top end of the canopy 1.

[0055] The working principle of the sunshade umbrella 100 integrated with photovoltaic panels of the present embodiment is as follows:

[0056] Since the present embodiment does not use a single photovoltaic panel fixed to the top end of the canopy 1, but multiple photovoltaic panels are distributed circumferentially around the top end of the canopy 1, the total area of the photovoltaic panels can be significantly increased, thereby improving the photovoltaic power generation power and the electrical energy output capacity to meet the actual use requirements.

[0057] As a possible example, in the present embodiment, referring to FIGS. 1-4, the canopy 1 forms multiple canopy units after being folded, and two adjacent canopy units are separated by an upper convex fold 11 formed by the supporting ribs. One end of the upper convex fold 11 points to the top end of the canopy 1, and the other end of the upper convex fold 11 points to the edge of the canopy 1. The photovoltaic panels include a first photovoltaic panel 4 confined within one canopy unit, and the distribution form of the first photovoltaic panel 4 can refer to FIGS. 5-22. Since the first photovoltaic panel 4 is confined within the corresponding canopy unit and does not cross the fold, it is convenient for folding and opening the sunshade umbrella. The first photovoltaic panels 4 on both sides of the fold are preferably symmetrical about the fold. The symmetrical distribution form can improve the uniformity of the force received by the canopy 1, thereby making the sunshade umbrella more stable after being opened.

[0058] As a possible example, in the embodiment, referring to FIG. 23-27, the sunshade umbrella 100 further comprises a flexible packaging bag 2 configured to position the first photovoltaic panel 4. The inner side of the flexible packaging bag 2 is provided with a wiring area 21 and a photovoltaic panel area 22, the wiring area 21 is configured to accommodate the wires, and the photovoltaic panel area 22 is configured to accommodate the first photovoltaic panel 4. The flexible packaging bag 2 is fixed to the upper surface of the umbrella cloth 1. At least the upper side of the photovoltaic panel area 22 can be light-transmitting. On the one hand, the flexible packaging bag 2 can protect the first photovoltaic panel 4 and the wires inside, and on the other hand, it can keep the first photovoltaic panel 4 and the wires inside in a stable position at all times. At least the upper side of the photovoltaic panel area 22 can be light-transmitting to ensure that the first photovoltaic panel 4 can generate electricity.

[0059] It can be understood that when the technical solution without the flexible packaging bag 2 is adopted, the first photovoltaic panel 4 can also be fixed on the umbrella cloth 1 in other ways, such as adhesion.

[0060] As a possible example, in the embodiment, the wiring area 21 is arranged along the upper convex fold 11. The number of photovoltaic panel areas 22 is multiple, and the multiple photovoltaic panel areas 22 are symmetrically distributed on both sides of the wiring area 21. The number of flexible packaging bags 2 is multiple, and the multiple flexible packaging bags 2 are evenly distributed along the circumference with the top end of the umbrella cloth 1 as the center.

[0061] The flexible packaging bag 2 adopts this radial distribution, the overall distribution is more uniform, and the uniformity of the force received by the umbrella cloth 1 is improved, so that the sunshade umbrella is more stable after being opened.

[0062] It can be understood that the wiring area 21 is arranged along the upper convex fold 11 is only a preferred embodiment. In actual use, the wiring area 21 can also be arranged at other positions.

[0063] As a possible example, in the embodiment, the power supply circuit 3 comprises a box body 31, a bus circuit board and first and second wires.

[0064] The box body 31 is fixed to the top end of the umbrella cloth 1, and the umbrella cloth 1 below the box body 31 is provided with a wire passing hole. The bus circuit board is installed in the box body 31. The first wire 32 passes through the side wall of the box body 31 and the wiring area 21, one end of the first wire 32 is connected to the first photovoltaic panel 4 in the photovoltaic panel area 22, and the other end of the first wire 32 is connected to the bus circuit board. The second wire passes through the wire passing hole, one end of the second wire is connected to the bus circuit board, and the other end of the second wire is located below the umbrella cloth 1.

[0065] The current output by the first photovoltaic panel 4 is converged into the bus circuit board through the first wire 32, and then the second wire outputs the electric energy below the umbrella cloth 1.

[0066] As a possible example, in the embodiment, the first wire 32 is a flat wire. The thickness of the flat wire is small, and it is easier to be packed in the wire area 21.

[0067] As a possible example, in the embodiment, the flexible packing bag 2 is fixed on the umbrella cloth 1 by sewing, and / or the flexible packing bag 2 is fixed on the umbrella cloth 1 by magic tape. That is, the flexible packing bag 2 can be fixed on the umbrella cloth 1 by at least one of the sewing and the magic tape. When only the magic tape is used, it is convenient to install and remove. When the sewing is used, the fixing effect is better.

[0068] As a possible example, in the embodiment, referring to FIG. 24, the flexible packing bag 2 includes a composite film layer 23 and a sealing layer 24, the composite film layer 23 is connected to the outside of the sealing layer 24, and the connection between the composite film layer 23 and the sealing layer 24 can be adhesion. The sealing layer 24 is configured to prevent water from entering, and the composite film layer 23 can provide a certain strength to reduce the abrasion of the sealing layer 24. In the flexible packing bag 2, for the part outside the wire area 21 and the photovoltaic panel area 22, the upper sealing layer 24 and the lower sealing layer 24 can be connected as a whole to limit the movement of the first wire 32 and the first photovoltaic panel 4. For example, the material of the sealing layer 24 can be EVA (ethylene-vinyl acetate copolymer), and the material of the composite film layer 23 can be PET (polyethylene terephthalate) or ETFE (ethylene-tetrafluoroethylene copolymer).

[0069] As a possible example, in the embodiment, the sunshade umbrella 100 integrated with the photovoltaic panel further includes an electric appliance, the electric appliance is installed on the umbrella rib, and the power supply line 3 is connected to the electric appliance to supply power to the electric appliance. The second wire can be selected to directly supply power to the electric appliance, or the second wire is first connected to an intermediate circuit board, and a third wire led out from the intermediate circuit board is used to supply power to the electric appliance.

[0070] As a possible example, in the embodiment, the electric appliance includes at least one of a lamp and a fan to meet the needs of lighting, cooling, and insect repelling during outdoor activities.
