Abstract

The invention relates to a portable and light solar mobile power supply capable of being folded, and belongs to the technical field of solar application. The invention aims to solve the problems thata cell panel is easy to damage and is poor in reliability brought by the fact that the volume of the solar panel becomes small and the integral structure is more compact due to a key technology of solar charging portability and volume getting smaller. The solar mobile power supply provided by the technical scheme is technically characterized in that a multi-layer circuit board is used for packaging, a rotation shaft type electrode is used for connecting, the solar mobile power supply is reliable to charge, and a solar cell array is rapid to expand. The solar panel of the mobile power supply isformed, a rotation shaft type electrode on a back-contact battery chip patch PCB is led out, a charging controller is externally connected, a charging box-type mobile power supply capable of being folded and storing is formed, and a busbar is expanded by the solar panel so that a charging control device is used for storing energy and charging. With the adoption of a core technology of a berylliumcopper rotation shaft type electrode to connect, electrical connection among electrodes is improved, and the solar mobile power supply is resistant to wear and is high in electrical conductivity andhigh in reliability.

Description

Technical field [0001] The invention discloses a portable light, thin and foldable solar power source, which adopts multilayer circuit board packaging, rotating shaft electrode connection, and rapidly expands the solar array, belonging to the technical field of solar energy application. Background technique [0002] In the era of Internet big data, electronic products are extremely abundant, mobile phones are carried with you, and more and more digital electronic products need fast charging at any time. Especially with the changes in people's travel patterns, solar mobile power came into being and has become an indispensable item to carry. Especially in outdoor areas, areas without electricity, border guards, etc., solar mobile power is not limited to outdoors, and it is also suitable for other solar mobile power required for DIY. Solar mobile power is becoming more and more popular. Solar cells (panels) convert light radiation into electrical energy, and their efficacy is propo...
