Abstract
A foldable computing device comprises a first portion, a second portion, a hinge assembly rotatably coupling the first portion to the second portion, and a flexible display. The hinge assembly includes a hinge core, a timing element, a first linkage component rotatably coupling the hinge core to the first portion, a first hinge guide rotatably coupling the hinge core to the first portion, a second linkage component rotatably coupling the hinge core to the second portion, and a second hinge guide rotatably coupling the hinge core to the second portion. The first linkage component defines one or more helical surfaces that interface with the timing element, and the second linkage component defines one or more helical surfaces that interface with the timing element. The timing element coordinates rotation of the first linkage component with rotation of the second linkage component.
