Abstract: A portable information handling system rotationally couples housing portions with a variable torque hinge having a first axle that rotates with a first housing portion, a second axle that rotates with a second housing portion and a synchronizing gear assembly that translates rotation between the first and second axles. Variable torque is applied by selectively engaging and disengaging a coupler gear with the synchronizing gear assembly to apply and remove an increased torque that resists housing rotation. In one embodiment, the coupler gear is an idler gear of the synchronizing gear mechanism that selectively applies and removes an increase torque of the second axle to the first axle. The coupler gear slides in response to an actuator, such as an electro-permanent magnet acting on a ferromagnetic material with high and low magnetic attraction states.

Abstract: A portable information handling system housing rotationally couples housing portions with a dual axis synchronized gear to rotate about parallel spaced axes that define a radius to support folding of a flexible display. Each axis of the synchronized gear couples to a housing portion with a sliding bracket that adjusts length during rotation. Plural pivot arms couple to a main body of the hinge at the first and second axes and to the housing portions to manage spacing of the housing portions during rotation. A sliding member coupled to the main body engages with the plural pivot arms to synchronize rotation of the plural pivot arms and regulate torsional forces related to rotation of the housing portions that can damage a display film folding at the hinge.
