US Patent 10036188 Hinge and a foldable electronic device with the same

A hinge includes a base frame, a mechanically transmitting assembly and two support frames. The base frame defines two guideways disposed opposite to each other in a front-and-rear direction. The mechanically transmitting assembly is mounted on the base frame and partly disposed in the guideways. Each support frame has an arcuate frame body slidably engaging the respective guideway and coupled with the mechanically transmitting assembly, and a support frame body disposed outwardly of the base frame. The support frames are rotatable about a rotating axis relative to the base frame to make synchronous rotation in opposite rotational directions through the mechanically transmitting assembly. The rotating axis is disposed above the base frame.
