Abstract

This application provides a hinge mechanism and an electronic device. One example hinge mechanism includes a base, and a first rotating assembly and a second rotating assembly that are respectively disposed on two sides of the base. When the first rotating assembly and the second rotating assembly rotate toward each other, a length of the hinge mechanism may be increased; or when the first rotating assembly and the second rotating assembly rotate opposite to each other, a length of the hinge mechanism may be shortened, and a support surface for supporting a flexible display can be formed.
