Abstract: Embodiments of this application provide a foldable electronic device, including a shaft cover, a device body, and a first swing arm; a second swing arm coupled to a damping component inside the shaft cover and distributed in parallel to the first swing arm; and a pin connecting the first swing arm and the second swing arm so that the second swing arm follows the first swing arm to rotate and transmits a damping force produced by the damping component to the first swing arm through the pin. In the electronic device according to the embodiments of this application, fitting between the annular groove and the boss increases a sectional area of a joint between the first swing arm and the second swing arm and reduces shear stress experienced by the pin, avoiding fracture of the pin under undesirably large shear stress, thereby improving reliability of the device.

Abstract: This application discloses a synchronous rotation mechanism and a foldable electronic device, and relates to the field of electronic device technologies. The synchronous rotation mechanism is used in a foldable electronic device. The synchronous rotation mechanism includes torque swing arms and a sliding member. The torque swing arms on two sides of the sliding member are connected by the sliding member. The torque swing arms are rotatably connected to the sliding member by sliders and helical slots, so that when the torque swing arm on one side rotates, the slider and the helical slot synchronously drive the sliding member to slide in a direction perpendicular to rotation of the torque swing arm, and then to drive the torque swing arm on another side to rotate synchronously.
