A hinge device of a portable terminal having a foldable structure, according to the present invention, comprises: a housing positioned between one-end portions of a first body and a second body; a first hinge blade and a second hinge blade fixed to the first body and the second body and rotationally supported on the housing to perform rotation movement as much as a predetermined angle between an 'unfolded position' at which the first body and the second body are placed on the same horizontal line and a ‘folded position’ at which the first body and the second body are facing and in contact with each other; and a slide member for interlocking the first hinge blade and the second hinge blade to perform a relative motion, wherein a first inclined guide protrusion and a second inclined guide protrusion are formed on bottom surfaces of the first hinge blade and the second hinge blade, a first inclined guide groove and a second inclined guide groove are formed on a top surface of the slide member in correspondence thereto, and the slide member is installed in the housing to reciprocate a predetermined distance in a direction of hinge axis line.

Hinge device of portable terminal having foldable structure

A hinge device of a portable terminal with a foldable structure according to the present invention includes: housing positioned between one end of a first body and one end of a second body; first hinge blade and second hinge blade fixed to the first body and the second body, respectively, and supported against the housing to rotate at a predetermined angle between an 'unfolded position' in which the first body and the second body are placed on the same horizontal line and a ‘folded position’ in which the first body and the second body face each other and thus come into contact with each other; and first interlocking gear and second interlocking gear for interlocking the first hinge blade and the second hinge blade with each other so that the first hinge blade and the second hinge blade move relative to each other, wherein the first interlocking gear and the second interlocking gear are mounted on the corresponding housing in such a way as to rotate relative to each other by a predetermined angle around gear shafts by engaging with each other and, on the upper sides of the first interlocking gear and the second interlocking gear a plurality of first gear-side protrusions and second gear-side protrusions are arranged radially in circumferential directions around the gear shafts, and on the undersides of the first hinge blade and the second hinge blade a plurality of first blade-side protrusions and second blade-side protrusions engaging with the first gear-side protrusions and the second gear-side protrusions through rotations are arranged radially in circumferential directions around rotary axes of the first and second hinge blades.

Hinge device of portable terminal with foldable structure

A display device includes a display module, a supporting plate disposed under the display module, supporting bars disposed under the display module and arranged in a first direction with the supporting plate, a supporting film disposed between the display module and the supporting plate and between the display module and the supporting bars, a first case accommodating the display module, the supporting plate, the supporting film, and the supporting bars, and a second case coupled to the first case to move in a direction to be close to or to be far away from the first case along the first direction. Opposite sides of the supporting bars are respectively inserted into first guide grooves defined in inner side surfaces of the first case, which face each other in a second direction crossing the first direction, and the supporting bars move along the first guide groove.

Display device and method of manufacturing supporting part

A foldable display device includes a hinge, a support plate connected to opposite ends of the hinge and a display panel module disposed on the support plate. The hinge includes a rotation axis module having a rotation axis. A first slider is connected to the rotation axis and includes a first guide line. A second slider is connected to the support plate and includes a second guide line. A link arm includes a link arm body. The link arm body has a link arm rotation axis disposed at a first end of the link arm body and a link arm pin hole disposed at a second end of the link arm body. A link arm pin is configured to extend through the link arm pin hole, the first guide line and the second guide line.

Foldable display device

A foldable display device according to an exemplary embodiment includes a first body and a second body, and a hinge unit which is connected between the first body and the second body. The hinge unit includes a first joint which includes a first recess, a second joint which faces the first joint, a third joint disposed at one side of the first joint, a first leaf spring disposed in the first recess, and a first fastener fixed to the third joint through the first leaf spring and the first joint.
