Abstract
Proposed is a foldable hinge module for a portable terminal, and more particularly, a foldable hinge module for a portable terminal that can easily unfold or fold a flexible display mounted on the portable terminal. In the foldable hinge module for a portable terminal, the flexible display can be smoothly unfolded or folded as the first rotary plate and the second rotary plate are easily rotated in the Y axis direction, by using the gear set part engaged with the first gear part formed in the first rotary plate and the second gear part formed in the second rotary plate to be operated.
Claims8
A foldable hinge module for a portable terminal, comprising:
- a central support;
- a first rotary plate, one end of which is coupled to one side of the central support to be rotatable about a X axis and having a first gear part;
- a second rotary plate, one end of which is coupled to an opposite side of the central support to be rotatable about the X axis and having a second gear part;
- and
- a gear set coupled to the central support to be rotatable about a Z axis and operated while being engaged with the first gear part and the second gear part,
- wherein a flexible display is coupled to an upper surface of the first rotary plate and an upper surface of the second rotary plate,
- wherein the first rotary plate and the second rotary plate are rotated about the central support in a Y axis direction to be closer to each other or farther away from each other, and
- wherein the gear set is operated by the first gear part that is rotated in the Y axis direction when the first rotary plate is rotated about the X axis, and the second rotary plate is rotated about the X axis while the second gear part operated in conjunction with the gear set is rotated in the Y axis direction;
- wherein a central axis of rotation of the first rotary plate about the central support and a central axis of rotation of the second rotary plate about the central support are located on opposite sides in the Y axis direction with respect to the central line of the central support;
- wherein the first gear part protrudes downwards from one end of the first rotary plate and a first tooth shape is formed on a side surface of the first gear part,
- wherein the second gear part protrudes downwards from one end of the second rotary plate and a second tooth shape is formed on a side surface of the first gear part, and
- wherein the gear set is engaged with the first tooth shape and the second tooth shape between the first gear part and the second gear part such that the gear set is rotated about the Z axis when the first gear part or the second gear part is rotated in the Y axis direction;
- wherein each of the first gear and the second gear has an arc shape.
