The present invention relates to a field of outdoor umbrellas, and in particular to a foldable solar panel assembly applied to an umbrella or a sun canopy.
As a kind of outdoor leisure item, umbrellas are widely applied in squares, beaches, parks, gardens or similar places to shield an individual from wind, rain and sun. In order to enable umbrellas used outdoor to light at night, umbrellas with solar lights have appeared at present. The solar light umbrellas bring comfort and convenience to outdoor activities at night by solar power lighting/decoration in places such as beaches, open-air bars and coffee houses.
However, the solar cell panels of the solar light umbrellas in the current market are small in size and low in power, and high-capacity batteries cannot be arranged inside the solar light umbrellas, so the solar light umbrellas have a very short lighting duration and cannot provide long-time lighting.
After searching, a Chinese patent CN205005009U (patent No.: CN201520697240.1) disclosed a foldable solar panel, comprising two rectangular fixed frames, two rectangular panel bodies and a plurality of connecting blocks, wherein the panel bodies are fixedly connected in the fixed frames; the connecting blocks are rectangular and have end faces and side faces located on two sides of the end faces; support columns are vertically connected to the end faces; guide slots are formed on the connecting blocks on two sides of the support columns; one end of each guide slot extends to the support column, while the other end thereof extends to the side face of the connecting block; connecting grooves are formed on two opposite walls of each guide slot in a lengthwise direction; a plurality of connecting columns are arranged on one edge of each fixed frame in the lengthwise direction, and connecting pins are vertically arranged at free ends of the connecting columns; the connecting columns are slidingly inserted into the guide slots, and the connecting pins are slidable in the connecting grooves; positioning members which fix the two panel bodies when the side faces of the two panel bodies are in the same plane or when the side faces of the two panel bodies are parallel are arranged between the connecting columns and the connecting blocks; legs are vertically arranged on the side faces of the free ends of the fixed frames; and, when the side faces of the two panel bodies are in the same plane, the ends of the legs are flush with the ends of the support columns. This solar panel is also foldable and is used in the photovoltaic systems of buildings to solve the problem of storage, but the solar panel problem of solar light umbrellas cannot be solved.
