Motorized mechanism for operating head of humanoid figurine, has actuators causing tilting of frame about pivot axes via thrust unit in side of bearing, and rod that is allowed to take-up rigid structure of kinematic chain

摘要

The mechanism has a kinematic chain comprising a set of actuators (18, 19) engaged with a set of rigid structures (12, 13) via transmitting units (20, 21), respectively. A frame (5) is engaged on a thrust unit and pivotally mounted on the rigid structures about pivot axes (ABF, ABL). The actuators cause tilting of the frame about the pivot axes via the thrust unit in a side of a bearing. A rod (6) is allowed to take-up the rigid structure of the kinematic chain.
