Abstract: A movement mechanism applied to an inner-folding flexible screen terminal, comprising an intermediate support structure, the intermediate support structure being provided with a flexible screen support surface, a left-side rotation connection structure and a right-side rotation connection structure, a left-side connecting member and a right-side connecting member; inner ends of the left-side rotation connection structure and the right-side rotation connection structure are both rotatably connected to the intermediate support structure, the left-side connecting member and the right-side connecting member are respectively rotatably connected to outer ends of the left-side rotation connection structure and the right-side rotation connection structure, and the left-side connecting member and the right-side connecting member are respectively slidably connected to a left-side support frame and a right-side support frame.

Abstract: A hinge, a left rotating bracket and a right rotating bracket of the hinge being respectively provided on a left linkage mechanism and a right linkage mechanism and being respectively connected to a middle support frame by means of the left and right linkage mechanisms A synchronization structure is provided between the left and right linkage mechanisms such that the left and right rotating brackets simultaneously rotate in a reverse direction; the left and right rotating brackets are respectively provided with sliding connection slots; the left and right sides of the middle support frame are respectively provided with mechanisms for providing rotational resistance; moreover, rotating members in the mechanisms providing rotational resistance on the left and right sides are each provided with a connection arm; the mechanisms are slidably connected to the sliding connection slots of the left and right rotating brackets by means of the connection arms, respectively.
