Abstract: Embodiments of this application disclose a folding mechanism and a mobile terminal. The folding mechanism includes a bracket and two support assemblies, with the two support assemblies respectively located on two sides of the bracket in a width direction. The support assembly includes a first support, a second support, and a swing arm, with the second support and the swing arm located on a same side of the first support. Because the second support and the first support are slidably connected rather than pivotally connected, the second support and the first support can be considered as one telescopic rod as a whole. Therefore, the bracket, the second support, the first support, and the swing arm form an equivalent three-rod linkage mechanism. In comparison with the related art, one linkage rod is saved, shortening a tolerance chain, which helps reducing a total tolerance of the folding mechanism.
