Patent attributes
A hinge structure includes: a base having an axial hole whose an inner wall has positioning concave portions; at least one torque element, disposed in the axial hole and includes a torque providing portion and positioning convex portions; and a rotation shaft, passing through the through hole. The torque providing portion surrounds a central axis of the axial hole to form a through hole, the torque providing portion has a fracture adjacent to the through hole, and the positioning convex portions are connected to the torque providing portion and correspond to the positioning concave portions respectively. The torque providing portion and the positioning convex portions are located on a same virtual plane perpendicular to the center axis. A first virtual straight line on the virtual plane passes through the fracture and the center axis, and at least some positioning convex portions are not located on the first virtual straight line.
