Abstract
A hinge assembly includes a body drive member (1), a cover drive member (2), and a locating member (3). The body drive member has an outer screw thread (16) on an outer periphery thereof. The cover drive member has a central cavity (212, 224), and a projection (223) and an inner screw thread (216) formed in the cavity. The locating member has a projection (31) formed on an outer periphery thereof, and a central hole (33). The body drive member extends through the cavity and the hole, thereby integrating the hinge assembly into a complete unit, with the thread of the body drive member engaging with the thread of the cover drive member, and the projection of the cover drive member movably engaging with the projection of the locating member. The hinge assembly exerts reduced force on a foldable electronic device when the foldable electronic device is opened or closed.
