1. A hinge structure comprising:
a fixed structure comprising a first guide rail and a second guide rail, the first guide rail and the second guide rail having an arc shape, a center of an arc of the first guide rail being a first axis of rotation parallel to an axial direction, and a center of an arc of the second guide rail being a second axis of rotation parallel to the axial direction;
a first rotary structure comprising a first guide portion and a first helical groove, the first guide portion being accommodated in the first guide rail, the first helical groove extending at least partially around the first rotary structure and along a portion of the first rotary structure, the first rotary structure being configured to rotate about the first axis of rotation;
a second rotary structure comprising a second guide portion and a second helical groove, the second guide portion being accommodated in the second guide rail, the second helical groove extending at least partially around the second rotary structure and along a portion of the second rotary structure, the second rotary structure being configured to rotate about the second axis of rotation; and
a sliding structure comprising a first guide protrusion and a second guide protrusion, the first guide protrusion being accommodated in the first helical groove, the second guide protrusion being accommodated in the second helical groove, the sliding structure being configured to slide in the axial direction relative to the fixed structure in response to the first rotary structure and the second rotary structure rotating.
