Abstract: A hinge device includes a fixed shaft, a rotating sleeve, a fixed connection member, a torsion spring, a rotating connection member and a friction resistance assembly. The rotating sleeve is rotatably mounted on the fixed shaft and is located between a fixed end and a free end. One end of the fixed connection member is fixedly connected to the free end, and the other end is provided with a first slot. Two ends of the torsion spring are respectively equipped with a first snap-in pin and a second snap-in pin. The first snap-in pin inserts into the first slot. An extension part protrudes from a fixed part of the of the rotating connection member and is provided with a second slot. The second snap-in pin inserts into the second slot. The friction resistance assembly is disposed on the fixed shaft to provide torsional resistance to the rotating sleeve.

Abstract: A torque-variable single-shaft rotary shaft structure with multiple frictional pairs includes a pivot shaft. A first support is secured to a pivot shaft and a second support is disposed on the pivot shaft. An adjustment wheel assembly, a frictional assembly and an elastic assembly are fitted on the pivot shaft. The adjustment wheel assembly and the frictional assembly have a first adjustment wheel and a second frictional member synchronously movable with the first support and a second adjustment wheel and a first frictional member synchronously movable with the second support. When the first and second supports are rotated, the first and second adjustment wheels are driven to contact and abut against each other so as to provide axial action forces. The frictional assembly has multiple first and second frictional members, which are alternately arranged in frictional contact with each other to form multiple frictional pairs.
