Description

Water drop shaped hinge structure {WATER DROP SHAPED HINGE STRUCTURE}

The present disclosure relates to a waterdrop-shaped hinge structure, and more specifically, to a hinge structure in which the length of a display disposed adjacent to the hinge is maintained constant even when the state of the hinge structure changes.

As display technology develops, electronic devices utilizing flexible displays are being developed. Flexible displays have the advantage of being able to change their shape, such as by folding or bending, improving portability and reducing the volume of electronic devices.

Flexible displays can be implemented in the form of organic electroluminescence displays, liquid crystal displays, etc. According to one embodiment, in existing organic electroluminescent displays and liquid crystal displays, a change in the shape of a flexible display can be implemented using a flexible material such as a plastic film.

As the shape of the flexible display changes, displacement occurs radially inward and radially outward of the flexible display, resulting in internal stress in the area where the shape changes. Generally, compressive force occurs on the radial inner side of a flexible display, and tensile force occurs on the radial outer side. As such compressive and tensile forces occur repeatedly, the durability of the flexible display may decrease and further result in defects in the electronic device.

In order to minimize wrinkles that occur on the flexible display adjacent to the axis when folding or unfolding the flexible display around an axis, a hinge structure that can minimize the displacement between the radial inside and outside of the flexible display is needed.

According to various embodiments of the present disclosure, the hinge structure includes a main body having a longitudinal direction, a width direction, and a height direction, and at least one connected to the main body and configured to rotate about the first portion of the main body. A limit lever, at least one link lever connected to the main body and configured to rotate about a second portion of the main body, at least one link lever connected to the main body and configured to rotate about a third portion of the main body One free-stop lever, at least one main frame connected to the limit lever, a sub-frame disposed below the main frame, at least one sub-frame connected to the free-stop lever, and an inclined plate connected to the main frame, At least one swash plate including a swash plate body below the swash plate, the link lever is connected to the main frame or the sub-frame, the swash plate body is connected to the sub-frame and the free-stop lever, and the limit lever , When the link lever and the free stop lever rotate around the main body, the main frame, the sub frame, and the swash plate are configured to move from the limit lever, the link lever, and the free stop lever. It can be configured to move along a predetermined orbit centered on the moving rotation axis.

According to various embodiments of the present disclosure, an electronic device, in a hinge structure, may further include a first housing disposed on one side of the hinge structure and a second housing disposed on the other side of the hinge structure.

The waterdrop-shaped hinge structure according to various embodiments of the present disclosure can maintain the arc length of the folded portion of the flexible display constant between when the flexible display is fully unfolded and when it is fully folded, thereby eliminating wrinkles occurring at the folded portion. It can be minimized.
