ROTATING SHAFT MECHANISM AND MOBILE TERMINAL

This application provides a rotating shaft mechanism and a mobile terminal. A connection rod and a swing arm are separately rotatably connected to a primary shaft component, and during rotatable connection, an axis around which the swing arm rotates and an axis around which the connection rod rotates are different, so that the swing arm and the connection rod rotate and slide relative to each other. In addition, the swing arm or the connection rod drives a support plate to rotate, so that the primary shaft component and the support plate can encircle to form, during folding, space that accommodates a folded part of a flexible display, thereby improving a bending effect of the flexible display. In addition, based on rotation of the connection rod and sliding and rotation of the swing arm relative to a rotating shaft, a thickness of a foldable mechanism after folding is approximately equal to a thickness of two housings that are stacked together, thereby improving a folding effect of the mobile terminal.
