FLEXIBLE PRINTED CIRCUIT BOARD ASSEMBLY AND ELECTRONIC DEVICES

Abstract

This invention refers to a flexible printed circuit board assembly and electronic devices. The flexible printed circuit board assembly includes the flexible printed circuit board and the control structure. The control structure consists of a transmission element and two winding shafts spaced apart on the transmission element. The flexible printed circuit board runs between the two winding shafts. The transmission element is designed to control the rotation of the two winding shafts, so that the flexible printed circuit board is wound around all the outer surfaces of the two winding shafts. Alternatively, the control structure includes the transmission element, a guide shaft, and a connecting element. The guide shaft is placed on the surface of the flexible printed circuit board. The connecting element has one end positioned on the transmission element and the other end connected to the guide shaft.The transmission mechanism is designed to control the connecting mechanism to control the guide shaft's movement, and the guide shaft is designed to control the bending of the flexible printed circuit board. The transmission mechanism controls the movement of the winding or guide shafts and creates a bending guide for the flexible printed circuit board, so that the excess length of the flexible printed circuit board is bent to form a circular arc or curve, thereby avoiding stress concentration and increasing the lifespan of the flexible printed circuit board.
