An electronic device includes a display including a first area, a second area, and a folding area that is between the first area and the second area, a first housing supporting the first area, a second housing supporting the second area, and a hinge assembly foldably connecting the first housing and the second housing to be foldable with respect to each other between a folded state in which the first area and the second area face each other, and unfolded state in which the first area and the second area do not face each other, where the hinge assembly includes a hinge bracket including two fixed cams and two first rail structures, the hinge bracket defining two hinge axes and two hinge structures each rotatably connected to a respective one of the two first rail structures.

Electronic device comprising hinge assembly

An electronic device is provided. The electronic device includes a display extending from a first housing to a second housing, and a hinge structure rotatably connecting the first housing and the second housing and including a fixed member, a first rotary member coupled to the fixed member so as to be rotatable about a first axis extending parallel to an axial direction and connected with the first housing, a second rotary member coupled to the fixed member so as to be rotatable about a second axis parallel to the axial direction and connected with the second housing, a first guide member coupled to the first rotary member so as to be rotatable about a third axis parallel to the first axis, a second guide member coupled to the second rotary member so as to be rotatable about a fourth axis parallel to the second axis, a first rotary plate at least partially coupled to the first guide member to rotate about the third axis with the first guide member and supporting a partial area of the display, and a second rotary plate at least partially coupled to the second guide member to rotate about the fourth axis with the second guide member and supporting another partial area of the display. When the first housing or the second housing is folded or unfolded, the first rotary member rotates about the first axis in a first rotational direction, the first guide member and the first rotary plate rotate about the third axis in the first rotational direction, the second rotary member rotates about the second axis in a second rotational direction opposite to the first rotational direction, and the second guide member and the second rotary plate rotate about the fourth axis in the second rotational direction.

Electronic device including hinge structure

Disclosed is a foldable electronic device including a flexible display, a first housing and a second housing, a hinge housing, and a hinge structure. The hinge structure includes a first rotary member coupled to the first housing, a second rotary member coupled to the second housing, a first arm part coupled to the first rotary member and including a first rotary cam, a second arm part coupled to the second rotary member and including a second rotary cam, a fixed cam part including a first fixed cam engaged with the first rotary cam, a second fixed cam engaged with the second rotary cam, and a cam body connecting the first fixed cam and the second fixed cam, a stopper that restricts rotational angles of the arm parts, and an additional structure disposed between the stopper and the fixed cam part.

Hinge structure and foldale electronic device including the same

An electronic device includes a housing including a first housing and a second housing, a display extending from the first housing to the second housing, and a hinge structure including a hinge connected to the first housing and the second housing. The hinge structure includes: a fixed portion, a first rotary portion coupled to the fixed structure to be rotatable about a first axis of rotation and connected to the first housing, a second rotary portion coupled to the fixed portion to be rotatable about a second axis of rotation and connected to the second housing, the first axis of rotation and the second axis of rotation extending parallel to an axial direction, a first arm shaft rotatably coupled to the fixed portion and parallel to the axial direction, a second arm shaft rotatably coupled to the fixed portion and parallel to the axial direction, a first arm coupled to the first arm shaft and configured to rotate together with the first arm shaft and including a first arm cam formed around the first arm shaft, a second arm coupled to the second arm shaft and configured to rotate together with the second arm shaft and including a second arm cam formed around the second arm shaft, a first elastic member coupled to the first arm shaft and configured to apply an elastic force in the axial direction, a second elastic member coupled to the second arm shaft and configured to apply an elastic force in the axial direction.
