Abstract
An electronic device including a flexible display having a first region and a second region; a first frame supporting the first region and rotatable about a first axis; a second frame supporting the second region and rotatable about a second axis different than the first axis; and a hinge module connecting the first frame and the second frame and including a gear mechanism so the first frame rotatable about the first axis and the second frame rotatable about the second axis rotate in conjunction and synchronization with each other when the electronic device is folded and unfolded.
Claims19
An electronic device, comprising:
- a flexible display having a first region and a second region;
- a first frame supporting the first region and rotatable about a first axis;
- a second frame supporting the second region and rotatable about a second axis different than the first axis;
- and
- a hinge module connecting the first frame and the second frame so that the first frame rotatable about the first axis and the second frame rotatable about the second axis rotate in conjunction and synchronization with each other when the electronic device is folded and unfolded,
- wherein the hinge module further comprises:
- a first hinge module disposed on one side of the electronic device;
- a second hinge module spaced apart from the first hinge module in an axial direction;
- and
- a synchronization module configured to link the first hinge module and the second hinge module.
A folding device, comprising:
- a first frame disposed to be rotatable about a first axis;
- a second frame disposed to be rotatable about a second axis spaced apart and substantially parallel with the first axis the first axis;
- and
- a hinge module connecting the first frame and the second frame so that the first frame rotatable about the first axis and the second frame rotatable about the second axis rotate in conjunction and synchronization with each other when the folding device is folded and unfolded,
- wherein the hinge module further comprises:
- a first main gear rotating about the first axis in response to rotation of the first frame;
- a second main gear rotating about the second axis in response to rotation of the second frame;
- and
- auxiliary gears arranged between the first main gear and the second main gear and rotating in engagement with the first main gear and the second main gear.
