AI Technical Summary
Technical Problem
Existing bionic eyebrow drive solutions are too large to fit the limited space of bionic robot heads, and have limited motion precision and insufficient control reliability.
Method used
By employing an inner eyebrow drive unit and an outer eyebrow drive unit, combined with a crank-slider mechanism and a crank-rocker mechanism, two degrees of freedom of the inner eyebrow motion point can be independently controlled. The outer eyebrow motion point is connected by a flexible connector, reducing the superposition of multiple mechanisms.
Benefits of technology
It has achieved a compact bionic eyebrow structure that adapts to the confined space of a bionic robot head, with high motion precision, good control reliability, and rich and natural expressions.

Abstract
This invention relates to a biomimetic eyebrow structure, comprising an inner eyebrow driving unit and an outer eyebrow driving unit. In the inner eyebrow driving unit, a first driving source is connected to the inner eyebrow motion point via a crank-slider mechanism, driving the inner eyebrow motion point to move along a first direction. A second driving source is connected to at least a portion of the crank-slider mechanism via a crank-rocker mechanism, driving the inner eyebrow motion point to move along a second direction, namely, the up-down direction and the left-right direction. In the outer eyebrow driving unit, a third driving source is connected to the outer eyebrow motion point via an outer eyebrow transmission mechanism, driving the outer eyebrow motion point to move up-down and / or left-right. The invention also relates to a biomimetic robot head employing this biomimetic eyebrow structure. By combining the crank-slider mechanism and the crank-rocker mechanism to control the same inner eyebrow motion point, this invention avoids the space waste caused by simply stacking multiple mechanisms, making the overall structure more compact and easily adaptable to the space-constrained biomimetic robot head.
