Description

Technical Field

[0001] The invention relates to the field of photovoltaic technology, in particular to a photovoltaic stacked foldable expansion mechanism. Background Art

[0002] As the global demand for renewable energy grows, solar energy has received widespread attention as a clean and sustainable form of energy. Photovoltaic panels, as the core equipment for converting solar energy into electrical energy, play an important role in distributed power generation systems. However, traditional fixed photovoltaic panel installation methods usually require a large space and have many inconveniences during transportation and installation. In recent years, in order to adapt to different application scenarios, such as mobile emergency power supply, temporary event power supply, etc., various foldable or deployable photovoltaic panel designs have emerged. Although these designs have improved the portability and applicability of photovoltaic panels to a certain extent, they still have problems such as low efficiency, complex structure and inconvenient maintenance.

[0003] However, the existing foldable photovoltaic panel technology has the following main defects and shortcomings: 1. Efficiency issues: Some designs use complex mechanical structures, which leads to reduced energy conversion efficiency. For example, some automatic flipping mechanisms increase energy consumption and reduce the reliability of the overall system due to the presence of frequently moving parts. 2. Structural complexity: Many existing foldable photovoltaic panels are too complex in design, which increases manufacturing costs and maintenance difficulties. 3. Portability and ease of use: Although some products on the current market claim to have good portability, they fail to fully meet the needs of users in actual operation. 4. Adaptability limitations: The current design of most foldable photovoltaic panels does not fully consider the use requirements under different terrain conditions, which limits their scope of application. For example, in places with complex or uneven terrain, how to ensure the effective deployment and stable operation of photovoltaic panels remains a challenge.

[0004] In response to the above problems, the present invention provides a new photovoltaic panel stacking and foldable expansion mechanism, which solves a series of problems in the prior art such as low efficiency, complex structure, poor portability and limited adaptability through a unique design, greatly improving the transportation convenience and on-site construction efficiency of photovoltaic panels.
