Abstract
An electronic device has a hinge structure including a first fixed structure on which a first arc-shaped guide rail is formed, a second fixed structure on which a second arc-shaped guide rail is formed, a first rotating structure including a first coupling portion rotatably coupled to the first guide rail, a second rotating structure including a second coupling portion rotatably coupled to the second guide rail, and a torque structure which provides torque to the first rotating structure and the second rotating structure. The torque structure includes a cam structure formed on the first rotating structure and the second rotating structure, a cam member including a moving cam engaged with the cam structure, and an elastic member which is compressed or tensioned in response to linear movement of the cam member.

An electronic device comprising:
- a first housing;
- a second housing;
- and
- a hinge structure which is connected to the first housing and the second housing and by which the first housing and the second housing are rotatable, the hinge structure including:
- a first fixed structure including a first guide rail which has an arc shape and a center of which is a first rotation axis that is parallel to an axial direction;
- a first rotatable structure including a first coupling part coupled to the first guide rail and rotatable and a first extending part connected to the first housing, the first rotatable structure being rotatable about the first rotation axis together with the first housing;
- a first torque structure which provides a torque to the first rotatable structure, the first torque structure including:
- a first cam structure formed in the first coupling part;
- a first cam member including a first moving cam engaged with the first cam structure;
- and
- a first elastic member which is disposed between the first cam member and a first side wall of the first fixed structure and is compressed or prolonged in correspondence to linear movement of the first cam member;
- a second fixed structure including a second guide rail which has an arc shape and a center of which is a second rotation axis that is parallel to the axial direction;
- a second rotatable structure including a second coupling part coupled to the second guide rail and rotatable and a second extending part connected to the second housing, the second rotatable structure being rotatable about the second rotation axis together with the second housing;
- and
- a second torque structure which provides a torque to the second rotatable structure, the second torque structure including:
- a second cam structure formed in the second coupling part;
- a second cam member including a second moving cam engaged with the second cam structure;
- and
- a second elastic member which is disposed between the second cam member and a fourth side wall of the second fixed structure and is compressed or prolonged in correspondence to linear movement of the second cam member.

An electronic device comprising:
- a first housing and a second housing;
- a display disposed in the first housing and the second housing, wherein the display includes a folding area that is deformed to a curved surface or a flat surface;
- and
- a hinge structure which connects the first housing and the second housing and by which the first housing and the second housing are rotatable and define a predetermined included angle, the hinge structure including:
- a first rotatable structure which is rotated about a first rotation axis together with the first housing;
- a first elastic member which is compressed and prolonged through rotation of the first rotatable structure;
- a second rotatable structure which is rotated about a second rotation axis together with the second housing;
- and
- a second elastic member which is compressed or prolonged through rotation of the second rotatable structure,
- wherein the hinge structure includes:
- a folded detent section defined from a fully folded state to a first state, in which the included angle is a first included angle, wherein the first elastic member and the second elastic member are compressed by a first displacement as the included angle increases in the folded detect section;
- and
- a free-stop section defined from a second state, in which the included angle is a second included angle that is larger than the first included angle, to a third state, in which the included angle is a third included angle that is larger than the second included angle, wherein the first elastic member and the second elastic member has a predetermined compression state in the free-stop section regardless of the included angle, and
- wherein the first elastic member and the second elastic member are in a compressed state in which a first frictional torque that is higher than a restoring torque of the display is formed in the fully folded state.
