Abstract
An artificial eye structure rotates an artificial upper eyelid via the attraction between a number of electromagnetic elements disposed in a line and a magnet. The rotation angle of the artificial upper eyelid can be controlled by selectively magnetizing the electromagnetic elements.
Claims11
An artificial eye structure, comprising:
- an artificial eyeball being a hollow semi-sphere in shape and comprising a circular edge, a first outer surface, a pupil pattern formed on the first outer surface, and a pair of shaft sleeves correspondingly formed at the edge, the shaft sleeves being aligned with each other;
- a shaft rotatablely connected to the shaft sleeves;
- an artificial upper eyelid connected to the shaft and configured to rotate with the shaft;
- a gear sleeved on the shaft;
- a transmission rod comprising a teethed rack section meshed with the gear;
- a drive device comprising a plurality of electromagnetic elements disposed along a line, and a magnet fixed on the transmission rod;
- and
- a controller electrically connected to the electromagnetic elements for selectively magnetizing the electromagnetic elements, the magnetized electromagnetic element attracting the magnet and driving the transmission rod to move along the line of the electromagnetic elements and driving the shaft to rotate via the gear, the artificial upper eyelid rotating with the shaft to cover and uncover the pupil pattern.
