[0025] Example:

[0026] See also Figures 1-2 In this embodiment, the solar umbrella includes: an umbrella surface 1, a support rod 2 and a folding frame 3, the support rod 2 is fixed on the lower side of the umbrella surface 1, the folding frame 3 is arranged on the lower side of the umbrella surface 1 and connected to the support rod 2, a solar cell 4 is arranged on the upper side of the umbrella surface 1, and a battery connected to the solar cell 4 is arranged on the inner side of the support rod 2.

[0027] The support rod 2 is a steering ball type support rod, and a nut for locking the steering ball is provided on the steering ball type support rod. The support rod 2 can be stretched and folded, has a variety of angles, can support the umbrella surface 1 in multiple directions, can achieve the effect of light tracking and fast charging, and improves the defect that the original solar panel can only be charged in one direction.

[0028] The folding structure of the solar umbrella adopts a multi-frame folding structure and a wind-resistant double-frame design, which realizes the diversified folding and storage functions of the folding charging board of the solar umbrella, making it easy to carry and improving the defect of the original solar umbrella that it cannot be folded and stored. It adopts waterproof wiring technology and waterproof design, and the solar cell 4 is seamlessly connected to the umbrella surface, and the umbrella surface is seamlessly connected to the umbrella frame, so that the charging board is not easy to get water when the solar umbrella is folded, effectively protecting the cells in the solar panel, and improving the defect that the original solar panel cells cannot generate electricity when they come into contact with water.

[0029] In this embodiment, a plurality of solar cells 4 are arranged in a central ring around the umbrella cover 1, and two inner and outer circles of solar cells 4 are provided, wherein the outer solar cells 4 have a larger area, which can adapt to the folding of the umbrella cover 1 and ensure sufficient power generation area.

[0030] The solar umbrella replaces the traditional umbrella cover 1 with a solar folding charging panel, absorbs solar energy through the solar panel and converts it into electrical energy, so as to realize a device that can provide shade and shelter from rain, and can also provide electrical energy to electrical appliances. The specific principle is: when there is sufficient sunlight, the solar umbrella folding charging panel can provide shade and generate current and voltage under the action of sunlight, and use the wires led out of the solar panel and the solar multi-interface USB converter to charge or supply power to various electronic products or electrical equipment such as energy storage power supply boxes; when it rains and there is insufficient sunlight, it can provide shade and charge small electronic equipment. When charging other electronic products, the multi-interface USB converter output interface of the solar multi-folding charging panel can be used to charge by inserting it into the charging port of the relevant equipment. It is easy to carry and can meet the effective power supply needs of various electronic products without carrying batteries. It is suitable for emergency use of electrical equipment.

[0031] A solar multi-interface USB waterproof converter (including type-A, type-B and type-C interfaces, but not limited to these interfaces) is set in the solar umbrella, so that the solar-generated electricity can be charged through the fast charging protocol controlled by the converter. It can match mobile phones, mobile power supplies, power banks, mobile computers and other electronic products, solving the defect that the original solar panel can only be charged in a single way.

[0032] The upper end of the support rod 2 is provided with an LED lighting lamp 6, which is connected to a battery. In addition, a charging port 7 for charging the battery is provided at the lower part of the support rod 2. Two modes of charging the LED lighting lamp 6 by the solar panel are realized. One is to build a battery in the umbrella handle, and the energy storage includes 18650 lithium battery, button battery, nickel-chromium battery, nickel-metal hydride battery and other energy storage batteries, so as to realize energy storage charging; the other is to leave a Type-C charging port at the handle, top or end of the umbrella, and use a mobile power supply or a portable energy storage device with a discharge function to reversely power the LED lighting lamp 6, so as to realize the structural device of the umbrella lighting, and improve the defect that the original umbrella is used at night, which causes people to not see the road clearly and causes dangerous accidents.

[0033] The LED lighting lamp 6 is arranged at the folding frame 3 at the bottom of the umbrella, and a junction box is arranged at the position of the lifting ring. The junction box can have various interfaces for charging external electronic devices. The LED lighting lamp 6 can be partially turned on or off, and a switch for the LED light is arranged on the handle at the lower end of the support rod 2. The solar umbrella is used for sheltering from rain on rainy days, shading from the sun on sunny days, charging, and lighting on dim days.

[0034] See also Figure 3The solar cell 4 in this embodiment includes a back film 401, a cell 402, a front film 403 and a rainproof cloth 404 arranged from bottom to top, and a prepreg layer 405 is provided on both sides of the cell 402. The back film 401 is a polymer composite material, and the cell 402 includes polycrystalline silicon solar cells, single crystal silicon solar cells, amorphous silicon thin film cells, amorphous silicon flexible cells, sunpower and other solar cells. Through lamination or hot pressing, a high-efficiency solar flexible battery panel is formed, so that the solar panel can be bent, thereby forming a curved surface for diversified light-chasing movable charging, which improves the defect of the original solar panel single charging.

[0035] The prepreg layer 405 is provided with adhesive film layers on both sides, and the adhesive film layers are made of EVA material. The front film 403 is made of ETFE material. Compared with the original ordinary umbrella, this solar umbrella folding charging board adopts the lamination or hot pressing method of combining the ETFE high-transmittance transparent protective film with the battery sheet 402, which improves the light transmittance of the flexible folding process component, thereby improving the power generation efficiency of the solar umbrella folding charging board.

[0036] Compared with conventional solar panels, this solar umbrella folding charging board adopts two processes: flexible integrated lamination or hot pressing. It adopts unconventional processes such as ETFE (transparent films such as PET) lamination or epoxy resin substrate (including PCB / FR-4 / metal plates, etc.) lamination, which makes the battery cell 402 more stable and not shifted, and the solar panel is not easy to be scratched and damaged. It is also light in size and easy to carry.

[0037] See also Figure 4 The lower side of the umbrella 1 is provided with a heat dissipation chip 5 connected to the battery, and a plurality of heat dissipation chips 5 are evenly pasted and fixed on the lower side of the umbrella 1. The heat dissipation chip 5 is a semiconductor refrigeration chip, which can be cooled by the electric energy generated by the solar cell 4 to achieve sunshade and summer heat relief, improving the defect of the original solar umbrella that is very hot while shading in the hot summer, and can be widely used in places for sunshade and rain shelter, and emergency fast charging of electrical equipment.

[0038] The solar umbrella can realize that the solar panel can be used as an umbrella, and can also absorb the energy radiated by the sun, convert it into electrical energy for storage or direct use, so that resources can be effectively utilized and energy can be saved. It can block the sun, absorb solar energy, and can also be used as a charger, and has a simple structure, convenient use, and a wide range of applications. In summer, it can also be cooled by the heat dissipation chip 5, and has a simple structure, which solves the defect of being very hot in the hot summer.
