Abstract:
The present application provides a flexible circuit board assembly and an electronic device. The flexible circuit board assembly comprises a flexible circuit board and a control structure. The control structure comprises a transmission piece and two reels; the two reels are arranged on the transmission piece at an interval; the flexible circuit board passes between the two reels along an extension direction; and the transmission piece drives the two reels to rotate, so that the flexible circuit board is wound on the outer peripheral side of the two reels as a whole. Alternatively, the control structure comprises a transmission piece, a guide shaft, and a connection piece; the guide shaft is located at one side of the flexible circuit board; one end of the connection piece is provided on the transmission piece, and the other end of the connection piece is connected to the guide shaft; the transmission piece drives the connection piece to drive the guide shaft to move; and the guide shaft drives the flexible circuit board to bend. The transmission piece of the control structure drives the reels or the guide shaft to move and to provide bending guide for the flexible circuit board, such that a redundant length of the flexible circuit board is bent to form a roll or arc shape, stress concentration is avoided, and the service life of the flexible circuit board is prolonged.
