Movement mechanism applied to inner-folding flexible screen terminal and inner-folding flexible screen terminal

A movement mechanism applied to an inner-folding flexible screen terminal, comprising:

• an intermediate support structure, including a flexible screen support surface, wherein the intermediate support structure is connected to a left-side support frame and a right-side support frame through a synchronous reverse rotation connection mechanism,
• a left-side rotation connection structure,
• a right-side rotation connection structure,
• a left-side connecting member, and
• a right-side connecting member, wherein 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, the left-side connecting member and the right-side connecting member are respectively slidably connected to the left-side support frame and the right-side support frame, and sliding directions of the left-side connecting member and the right-side connecting member are perpendicular to rotation axes of the left-side support frame and the right-side support frame, and the left-side connecting member and the right-side connecting member are respectively arranged at connecting positions of a left-side casing and a right-side casing of the flexible screen terminal;
• wherein positions of rotation axes of the left-side rotation connection structure and the left-side support frame are configured in a mode that in a process from unfolding to folding of the flexible screen terminal, the left-side connecting member moves in a direction away from the intermediate support structure, and in a process from folding to unfolding of the flexible screen terminal, the left-side connecting member moves towards the intermediate support structure;
• wherein positions of rotation axes of the right-side rotation connection structure and the right-side support frame are configured in a mode that in the process from unfolding to folding of the flexible screen terminal, the right-side connecting member moves in a direction away from the intermediate support structure, and in the process from folding to unfolding, the right-side connecting member moves towards the intermediate support structure;
• wherein the rotation axes for rotation connection of the left-side rotation connection structure and the intermediate support structure and rotation connection of the right-side rotation connection structure and the intermediate support structure are both higher than the flexible screen support surface of the intermediate support structure and are close to or positioned at a height of a neutral layer of a flexible screen;
• wherein the intermediate support structure is internally provided pressing structures of the left-side rotation connection structure and the right-side rotation connection structure.
