Abstract: This application provides a rotating mechanism and an electronic device. The rotating mechanism includes a first housing connecting rod, a second housing connecting rod, a primary shaft, a first rotating door plate, a second rotating door plate, and a door plate swing arm. The first rotating door plate and the second rotating door plate are separately fixedly connected to the door plate swing arm. The door plate swing arm is rotatably connected to the primary shaft. The door plate swing arm is movably connected to the first housing, and the door plate swing arm is movably connected to the second housing. The first rotating door plate and the second rotating door plate are configured to support a bending portion of the flexible display screen in a flattened state. In a folded state, the first rotating door plate and the second rotating door plate form a screen accommodating space for accommodating the bending portion of the flexible display screen. This application can improve motion precision of the first rotating door plate and the second rotating door plate, and ensure stability and reliability of the electronic device.
