Pivot mechanism of foldable electronic device

A foldable electronic device, comprising:

• a cover, a base, and a pivot mechanism configured to rotatably couple the base to the cover, the pivot mechanism comprising:
• a connector;
• a first rotation assembly configured to be rotatably coupled to the base and fixedly attached to the connector;
• and
• a second rotation assembly configured to be fixedly coupled to the cover and rotatably coupled to the connector;
• the first rotation assembly, the second rotation assembly being configured to have a first configuration in which the angle between the base and the cover are at a minimum angle;
• the first rotation assembly being configured to rotate relative to the base and the second rotation assembly being configured to remain fixed relative to the connector as the angle between the cover and the base increases from the minimum angle to a first predetermined angle;
• the second rotation assembly being configured to rotate relative to the connector as the angle between the cover and base increases from the first predetermined angle to a second predetermined angle.
