Abstract

A connecting rod type hidden hinge comprises two relative connecting bases respectively disposed on an electronic device and a stand of the same; two sets of frame members disposed opposite to each other on the front and rear sides that are respectively assembled and linked with the surface of the relative connecting bases, so one end of the frame member becomes a fixed linking end and the other end becomes a free acting end to form a frame space; a torque connecting rod device disposed in the frame space comprising two joint blocks disposed oppositely to each other on the front and rear sides in a crossed manner and two torque members disposed between the two joint blocks along the left and right directions, wherein the joint blocks are connected with multiple connecting rods to be linked and form a free acting end. Thus, the joint blocks may generate the relative displacement along with the rotating process to form a smaller oblique crossed angle and to rotate to a position where they are nearly overlapped in the same direction. In addition, the invention may enable the opening/closing operation having a larger angle with a hidden type hinge structure.
