Abstract: A dual-torque hinge mechanism includes a rotary shaft, a second bridging component, a resistance assembly, a torque generating component and a driving assembly. The second bridging component is rotatably disposed on the rotary shaft. The resistance assembly is disposed on the rotary shaft and coupled to second bridging component. The torque generating component is coupled to the rotary shaft. The driving assembly is disposed between the resistance assembly and the torque generating component.

Abstract: A dual-torque hinge mechanism applied to an electronic device includes a rotary shaft, a first bridging component, a second bridging component, a first resistance component, a second resistance component and a torque generating component. The first and second bridging components are connected to the rotary shaft. The first and second resistance components are rotatably disposed on the rotary shaft. A stretching portion of the second resistance component is engaged with a positioning portion of the second bridging component. The torque generating component is fixed to the rotary shaft. A first driving portion of the first resistance component is not rotated when being pushed by a second driving portion of the torque generating component moving in a first rotation direction. The first driving portion is rotated when being pushed by the second driving portion moving in a second rotation direction different from the first rotation direction.

Abstract: A dual-torque hinge mechanism applied to an electronic device includes a rotary shaft, a first bridging component, a second bridging component, a first resistance component, a second resistance component and a torque generating component. The first and second bridging components are connected to the rotary shaft. The first and second resistance components are rotatably disposed on the rotary shaft. A stretching portion of the second resistance component is engaged with a positioning portion of the second bridging component. The torque generating component is fixed to the rotary shaft. A first driving portion of the first resistance component keeps inaction between the first resistance component and the second resistance component via a second driving portion of the torque generating component moving in a rotation direction. The first driving portion further moves the first resistance component relative to the second resistance component via the second driving portion moving in another rotation direction.
