The invention discloses a combined
facial expression simulation device, wherein the classic
mechanical transmission mode mainly dominated by a
cam mechanism is adopted, the operating personnel only needs to rotate a
handle to input power by virtue of a single-input and multiple-output structure, next, a main shaft and an auxiliary shaft drive a gear, a
cam and a connecting rod
assembly to move, and furthermore, a
cam assembly is driven to move and then an oscillating bar moves along with the cam
assembly, and then a steel
wire rope is pulled to drive each expression execution mechanism to move, and therefore, a complete
facial expression is formed; the steel
wire rope is guided by a flexible
pipe which can be bent arbitrarily without affecting sliding of the steel
wire rope therein, and as a result, the whole
system is enabled to be more stable in transmission and simple in structure. For switching expressions, a corresponding shifting fork is applied to shifting so that a corresponding cam group can move from side to side on a shaft to a predetermined position, the shifting fork is locked in a square groove and then the
handle is rotated to input power, and finally, another new
facial expression is formed by the expression
simulation device; the combined facial expression
simulation device is convenient to operate and control. The surface components are all designed to be modularized and convenient for
batch production.
