Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic devices, in particular to a large-area stretchable solar panel for an outdoor mobile device. Background Art

[0002] Solar power generation is a type of photovoltaic power generation technology. It's based on the photovoltaic effect, which uses sunlight to generate an electromotive force on solar panels (photovoltaic panels), converting solar energy directly into electricity. This process produces no greenhouse gas emissions, making solar energy a very clean, renewable energy source. Solar power generation is poised to become a trend in addressing resource shortages and replacing other energy sources. The photovoltaic power generation process involves several key factors, including the area of ​​the solar panels, conversion efficiency, the intensity and duration of sunlight exposure, the tilt angle and orientation of the panels, and cleanliness. Outdoor solar power stations require a large area for laying out the panels, typically in open suburban areas or on mountaintops. Smaller solar systems, either mounted on rooftops or on mobile devices, convert solar energy into electricity and store it in batteries. Smaller solar systems on mobile devices often have limited space, so multiple solar panels can be deployed when in use to maximize sunlight exposure and stored when not in use for easy mobility.

[0003] For example, Chinese patent application publication number CN113352902A discloses an on-board deployable solar power generation device for new energy vehicles. The solar power generation device disclosed in this application includes a multi-stage electric telescopic cylinder. When the telescopic rod of the multi-stage electric telescopic cylinder is extended, a support rod is positioned below the telescopic rod to support it. Each stage of the telescopic rod is provided with a hinged seat at the front end. A pair of hinged solar panels are positioned between each adjacent hinged seat. The edges of the solar panels are hinged to the adjacent hinged seats. When the telescopic rod of the multi-stage electric telescopic cylinder is extended, the solar panels unfold horizontally. When the telescopic rod of the multi-stage electric telescopic cylinder is retracted, the solar panels fold and are stored within a housing. Conventional solar panel storage is typically achieved through a "Z"-shaped folding structure, which is complex and costly. Furthermore, if one unit fails to extend or fold smoothly, the entire solar panel device can be disrupted. Utility Model Content
