Facial expression control device

A facial expression control device, comprising:

• a frame;
• a rotating element, pivoted to the frame and located therein, having a surface and a plurality of facial expression control structures, wherein each one of the facial expression control structures arranged in rows is disposed on the surface and has a shifting distance relative to the surface;
• a plurality of pushing bars arranged in at least one row and adapted to respectively prop against the facial expression control structures;
• an actuator connected to the rotating element so as to drive the rotating element to rotate;
• and
• a linking assembly disposed on an extending direction of the pushing bars, wherein the pushing bars are located between the rotating element and the linking assembly, thereby a movement of the pushing bars respectively propped against the facial expression control structures are linked to a plurality of facial expression control points and generate a corresponding facial expression, wherein the linking assembly comprises:
• a first assembling plate assembled onto the frame, wherein the pushing bars are inserted through the first assembling plate;
• a plurality of control bars driven by the pushing bars;
• and
• a rotating shaft penetrating through the control bars such that the control bars are adapted to pivot upon the rotating shaft as the control bars driven by the pushing bars;
• wherein the control bars has an axial direction, and an included angle is formed between the axial direction of the control bars and the axial direction of the pushing bars, thereby a rotating angle of the control bars relatively alters in accordance with the shifting distances of the facial expression control structures as the pushing bars respectively prop against the corresponding row of the facial expression control structures.
