An electronic device may include a display, a first housing, a second housing, and a hinge assembly configured to connect the first housing to the second housing and operate between a folded state and an unfolded state, wherein the hinge assembly may include a hinge bracket, a slider slidably connected to the hinge bracket and including a pair of reference cams and a pair of rotation rails configured to define a pair of hinge axes, a pair of rotators rotatably connected to the slider with the pair of hinge axes as centers, respectively, and both including a rotation cam configured to interoperate with the reference cams, and an elastic member configured to provide an elastic force in a direction in which the reference cam and the rotation cam press each other.

Hinge assembly and electronic device including the same

In an example embodiment, an electronic device may include a display, a first housing; a second housing, and a hinge assembly, wherein the hinge assembly may include a bracket structure, a pair of rotator structures respectively rotatable on a pair of hinge axes, a pair of arms respectively rotatable on a pair of arm axes, and each including an arm cam and a penetrating rail, a pair of pins respectively passing through the penetrating rails, connected to the rotator structure, respectively rotatable on a pair of pin axes, and each including a pin cam interoperating with the arm cam and a sliding guide slidable along the penetrating rail, and a pair of elastic members respectively connected to the pair of pins and each configured to press the pin cam toward the arm cam.

An arm structure of an electronic device is provided. The arm structure includes an arm body, a first cam disposed on one side of the arm body and including a first hole into which at least a portion of a rotating shaft providing a folding operation of the electronic device is inserted, a peak and a valley being formed around the first hole, a second cam arranged side-by-side on a same axis as the one side of the arm body, spaced apart from the first cam, and including a second hole into which at least a portion of the rotating shaft is inserted, a peak and a valley being formed around the second hole, and a connecting part disposed on another side of the arm body and fastened with a rotating part providing rotation of the electronic device.

Arm structure, hinge structure including the arm structure, and electronic device including the same

An electronic device is provided. The electronic device includes a display including a first area, a second area, and a folding area between the first area and the second area, a first housing configured to support the first area, a second housing configured to support the second area, and a hinge assembly configured to connect the first housing and the second housing, wherein the hinge assembly includes a hinge bracket including a pair of first rail structures formed to define a pair of hinge axes, a pair of hinge structures having one side connected to the first housing or the second housing and another side rotatably connected about the hinge axis along the first rail structure, and including a first cam structure. an intermediate member connected to the hinge bracket, and an elastic member configured to provide an elastic force to the intermediate member.

An electronic device is provided that includes a housing including a front plate facing a first direction, a rear plate facing a second direction opposite to the first direction, and a lateral member surrounding a space between the front plate and the rear plate and at least partially constructed of a metal material, wherein the front plate includes a first edge having a first length and extending in a third direction, a second edge having a second length longer than the first length and extending in a fourth direction orthogonal to the third direction, a third edge parallel to the first edge, having the first length, and extending in the third direction from the second edge, a fourth edge parallel to the second edge, having the second length, and extending in the fourth direction from the first edge, a first region in which the third edge and the fourth edge meet, and a second region in which the second edge and the third edge meet, a display viewable through the front plate, and an adhesive layer constructed in a closed-curve shape along the first edge, second edge, third edge, and fourth edge of the front plate, wherein, when viewed from above the display, a width of the adhesive layer in the first region and the second region is greater than a width of the adhesive layer outside the first region and the second region.
