(54) FLEXIBLE CIRCUIT BOARD ASSEMBLY AND ELECTRONIC DEVICE


(57) This application provides a flexible printed circuit assembly and an electronic device. The flexible printed circuit assembly includes a flexible printed circuit and a control structure. The control structure includes a transmission member and two reels arranged on the transmission member at an interval. The flexible printed circuit passes between the two reels. The transmission member is configured to drive the two reels to rotate, so that the flexible printed circuit is wound on entire peripheral sides of the two reels. Alternatively, the control structure includes a transmission member, a guide shaft, and a connecting member. The guide shaft is located on a side of the flexible printed circuit. The connecting member has one end arranged on the transmission member and an other end connected to the guide shaft. The transmission member is configured to drive the connecting member to drive the guide shaft to move, and the guide shaft is configured to drive the flexible printed circuit to bend. The transmission member of the control structure drives the reels or the guide shaft to move, and provides guidance for bending of the flexible printed circuit, so that a redundant length of the flexible printed circuit is bent to form an arcuate or circular arc shape, thereby avoiding stress concentration and increasing the life of the flexible printed circuit.
