Description

Technical Field

[0001] This utility model belongs to the technical field of generating electrical energy by converting infrared radiation, visible light or ultraviolet light; in particular, it relates to a lightweight solar power generation umbrella. Background Technology

[0002] A solar cell is a device that converts solar energy into electrical energy using the photoelectric effect of semiconductor materials. The basic process of the photovoltaic effect is as follows: Assuming light shines on a solar cell and is captured at the interface layer, photons with sufficient energy can excite electrons from covalent bonds in P-type and N-type silicon, resulting in electron-hole pairs. Before recombination, the electrons and holes near the interface layer are separated by the electric field of the space charge. Electrons move towards the positively charged N-region, and holes move towards the negatively charged P-region. Through the charge separation at the interface layer, a measurable outward voltage is formed between the P-region and the N-region.

[0003] There are various types of solar-powered sun umbrellas on the market. For example, Chinese Patent No. ZL2021207731427 discloses a solar-powered umbrella, which includes an umbrella canopy, a frame, an LED light, a flexible solar panel, an umbrella pole, a control compartment, and a battery. The frame is located at the top of the umbrella pole, the umbrella canopy is mounted on the frame, and multiple flexible solar panels are mounted on the top surface of the umbrella canopy. The control compartment is located in the middle of the umbrella pole and contains the battery. The LED light is mounted on the lower surface of the frame. The flexible solar panels and the LED light are electrically connected to the battery. The technical effect achieved is that this solar-powered umbrella effectively utilizes solar energy to charge the battery. In addition, it has a lighting function when used at night, and it also has the function of charging electronic devices by setting up a USB port. This type of solar-powered sun umbrella is very practical when placed outdoors, especially in the courtyard garden of a villa area. However, this type of solar-powered sun umbrella is large and heavy, making it difficult to move.

[0004] Making solar-powered sunshades lightweight and easy to carry is a research focus for those skilled in the art. For example, fishing trips often last for several hours. A lightweight solar-powered sunshade not only provides the sunshade function of a traditional sunshade but also powers the angler's mobile phone, eliminating anxiety about running out of battery during long fishing trips. It can also be connected to a small fan to provide a cool breeze during long waits. At night, it can be connected to an electric mosquito repellent and also provide lighting. Such a sunshade can provide very practical convenience for fishing enthusiasts. The same applies to other scenarios, providing users with a more convenient and practical experience than ordinary sunshades. Summary of the Invention

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0026] like Figure 1-4 This utility model discloses a lightweight solar-powered umbrella. The umbrella includes an umbrella pole and an umbrella head 1 fixed to the top of the pole. The umbrella head 1 includes an umbrella frame 5 fixed to the pole and an umbrella cloth mounted on the frame. A battery 10 and a control board 11 connected to the battery 10 are installed inside the pole. A power supply base 12 is provided on the bottom or side wall of the pole. The umbrella cloth is divided into an inner circle and an outer circle from the inside out. The inner circle includes an inner umbrella cloth 3 and an outer umbrella cloth 4 covering the inner umbrella cloth 3. The outer circle extends outward from the inner umbrella cloth 3. Flexible solar panels 2 are sewn onto the outer umbrella cloth 4 at both sides of the umbrella frame. The flexible solar panels 2 are connected to a positive conductive wire 24 and a negative conductive wire 25 located between the inner umbrella cloth 3 and the outer umbrella cloth 4. The other ends of the positive and negative conductive wires 24 and 25 are connected to the battery 10 inside the pole.

[0027] In this embodiment, the flexible solar panel 2 is sewn onto the inner ring of the umbrella fabric and located on both sides of the umbrella frame. The inner ring of the umbrella fabric adopts a double-layer structure of inner and outer umbrella fabric, and the conductive wire is sewn between the inner and outer umbrella fabric. This not only prevents the conductive wire from being soaked in water and leaking electricity on rainy days, but also makes it easier for the outer umbrella fabric to be folded up, making the solar power generation umbrella structure compact and lightweight, achieving the purpose of easy folding and transportation.

[0028] In this embodiment, solar energy is absorbed and generated by the flexible solar panel during use. The current enters the battery 10 through the positive conductive wire 24 and the negative conductive wire 25 to store energy. During use, the power is transmitted through the control board 11 and the power transmission base 12.

[0029] In this embodiment, while providing shade, the solar panel absorbs light energy and converts it into electrical energy, which can power mobile devices such as mobile phone charging, LED lighting, small fans, electric mosquito repellents, and other electrical appliances. This solar-powered sunshade is energy-saving, environmentally friendly, convenient, and practical. When not connected to any electrical equipment, the solar panel automatically charges the built-in battery, saving energy while providing convenient access when needed. For example, at night, it can be used with a spotlight for illumination or an electric mosquito repellent for mosquito control. Even on cloudy days or when sunlight is weak, when power generation is low, the battery can still power electrical equipment, maximizing sustainable power supply. It's ideal for outdoor fishing, backyards, or camping. For instance, when fishing, which can last for several hours, this solar-powered sunshade not only provides shade but also powers a mobile phone, eliminating worries about running out of battery during long fishing trips. It can also be connected to a small fan for cooling during long waits. At night, it can be used for mosquito repellent and lighting, offering great convenience for fishing enthusiasts. The same applies to other scenarios, providing users with a more convenient and practical experience than ordinary sunshades.
