None-angular displacement parallel damping device

A none-angular displacement parallel damping device mainly comprises a movable platform, a fixed platform, four branches and damper springs, wherein the branches are used for connecting the two platforms and are identical with one another in structure. One end of a first connecting rod in the branches is connected with the fixed platform through a first revolute pair, the other end of the first connecting rod is connected with one end of a second connecting rod through a second revolute pair, and the other end of the second connecting rod is connected with the movable platform through a cylindrical pair. The axis of the first revolute pair is parallel to that of the second revolute pair, and the axis of the second revolute pair is parallel to that of the cylindrical pair. The whole device is square. The four branches are symmetrically and evenly distributed. Four corners between the fixed platform and the movable platform are respectively and perpendicularly provided with one first damper spring, and the two sides of the cylindrical pair are respectively sleeved with one second damper spring. The none-angular displacement parallel damping device is simple in structure, small in occupied size, easy to process and high in cost-performance ratio, and has broad application prospect in many fields.
