FOLDABLE ELECTRONIC DEVICE INCLUDING HINGE ASSEMBLY

Document Type and Number:

WIPO Patent Application WO/2021/112549

Kind Code:

A1

Abstract:

An electronic device including a hinge assembly is provided. The electronic device includes a first housing, a second housing, a hinge assembly coupling the first housing and the second housing so that the second housing is rotatable with respect to the first housing, and a flexible display disposed from one region of the first housing to at least one region of the second housing across the hinge assembly. The hinge assembly includes a first bracket coupled to at least one region of the first housing to rotate about a virtual first rotation axis, a second bracket coupled to at least one region of the second housing to rotate about a virtual second rotation axis, a fixing bracket supporting the first bracket and the second bracket, a first shaft rotating about a third rotation axis different from the virtual first rotation axis, a second shaft adjacent to the first shaft to rotate about a fourth rotation axis different from the virtual second rotation axis, a first arm portion coupled to the first shaft to rotate about the third rotation axis, and having one side coupled to at least one region of the first bracket, a second arm portion coupled to the second shaft to rotate about the fourth rotation axis, and having one side coupled to at least one region of the second bracket, and a support portion located between the first arm portion and the second arm portion. The support portion supports at least one region of the flexible display when the electronic device is in an unfolded state, and is spaced apart from the flexible display as the electronic device rotates from the unfolded state to a folded state.
