Patent attributes
A hinge mechanism includes at least two hinge modules and at least one switching assembly disposed between the adjacent two hinge modules and including a first and second rotating members rotating coaxially with respect to each other. The first rotating member is coaxially disposed at one of the adjacent hinge modules to rotate synchronously. The second rotating member is coaxially disposed at the other one of the adjacent hinge modules to rotate synchronously. The first rotating member has a first driving portion, and the second rotating member has a second driving portion. The first and second driving portions are located on rotating paths of each other, and an idle stroke is provided between the first and second driving portions along the rotating paths. When the first driving portion and the second driving portion pass through the idle stroke, torque forces generated by the adjacent two hinge modules are disconnected.
