COUPLING ASSEMBLY FOR A FOLDABLE ELECTRONIC DEVICE

摘要

A foldable electronic device comprising a first and second housing element and a coupling assembly, including a linkage assembly and a biasing member, that directs the housing elements between a closed and a deployed orientation. The linkage assembly includes a plurality of adjacently disposed links collectively defining a first end and a second end. The first end is coupled to the first housing element and the second end is coupled to the second housing element. Each link is rotatably coupled to each adjacently disposed link and includes an outward limiting member limiting the relative rotation of adjacent links in an outward direction of rotation. The biasing member is coupled to the housing elements and outwardly biases the housing elements relative to each other to direct rotation of the housing elements toward the deployed orientation. The operable length of the biasing member changes as the housing elements are rotated toward the deployed orientation.
