[0002] A folding solar panel is a portable solar power generation device, usually formed by string-welding and laminating solar cells, which can be folded for easy carrying and storage. This kind of solar panel is widely used in outdoor activities, emergency rescue, camping, field work and occasions where temporary power supply is needed. The folding solar panel is light and easy to fold, convenient to carry and can adapt to various use environments. And it is usually equipped with simple fixing and connecting devices, which can charge various electronic devices outdoors.

[0003] In the existing folding panels, most of them are electrically connected by wires between multiple solar panels. However, the wires between the existing solar panels are prone to excessive bending after multiple foldings, forming fixed folding angles, which affects the overall folding effect of the solar panel in the later stage.

During the process of the solar panel 1 rotating and unfolding or rotating and storing, the wire 44 between each outer frame 2, under the action of the guiding spring 45, will only produce an arc-shaped bend angle even if it is bent. And under the action of the guiding spring 45, the wire 44 will not deform during the bending or resetting process, which can effectively solve the situation in the prior art that the wire 44 produces a fixed fold angle after being bent multiple times and will not be reset or even broken. By sleeving the guiding spring 45 on the wire 44, it effectively ensures that the wire 44 can still be reset to its original state after being bent multiple times, will not produce fold angles or breakage problems, and ensures the use of the solar panel 1 and the overall folding plate body, having good applicability and durability. After the use is completed, the operator can first store the support rod 51 and lock it through the elastic buckle plate 23, and then fold and store the folding plate body. After locking through the cooperation of the lock hole on the plastic lock plate 24 and the plastic lock block 25, the operator can carry away the entire folding plate body by grasping the grip 21. The structure is ingenious, efficient and convenient.
