The embodiment of the utility model discloses a flexible PCB structure. The PCB board structure is a single PCB board. Characterized in that it is characterized in that it comprises, the board at least comprises a first board surface, a second board surface, a third board surface, a first connecting part and a second connecting part, wherein the first plate surface and the second plate surface areconnected through the first connecting part, the second plate surface and the third plate surface are connected through the second connecting part, and the first connecting part and the second connecting part are both of a U-shaped slender strip structure. According to the PCB structure provided by the utility model, the connecting part is designed to generate tiny deformation so as to allow thefirst board surface, the second board surface and the third board surface to be in different planes. By adopting the utility model, on one hand, the problem that the plate splitting design is requiredto achieve the same purpose in the prior art is solved, the stability of the product structure is improved, the product quality is improved, on the other hand, the part design is optimized, and the weight and the cost of the product are reduced.
