Description
Technical Field
The present invention relates to a hinge device, and more particularly to a link type hinge device for a flexible display.
Background
With the development of flexible screen technology, the current portable electronic devices such as mobile phones and tablets have been designed to be foldable by applying the flexible screen, so that the electronic devices can be folded when not in use for convenient storage. Although the flexible screen has a certain flexibility compared to the conventional screen, it still needs to ensure that the screen has a large enough bending radius in the folded state, and at the same time, it needs to ensure that the flexible screen will not be stretched or squeezed during the folding and unfolding processes. In order to meet the requirement of flexible screen, the electronic device needs to use a link-type hinge to achieve the folding function.
However, although the link-type hinge can satisfy the requirement of the flexible display, it is not easy to generate stable resistance in the folding and unfolding processes to satisfy the use feeling.
In a conventional hinge of an electronic device, such as a notebook computer, a rotation resistance generator (or called torque generator) is disposed on a shaft center of the hinge, and when the hinge is rotated by an external force, the rotation resistance generator generates a strong reverse torque to the shaft center to slow down the rotation of the hinge, thereby providing a better use feeling. However, if the rotation resistance generator is disposed at the axis of the link-type hinge, the axis of the hinge must be designed to be thicker to bear the strong torque of the rotation resistance generator without damage, but the thicker axis will result in a large increase in the volume of the link-type hinge, and cannot satisfy the light and thin requirements of the portable electronic device.
Therefore, the link-type hinge of the prior art needs to be improved.
