1. Technical Field
The present disclosure relates to replicas of human organs, and particularly to a replica of an eye.
2. Description of Related Art
A typical replica of a human eye allow such simulations as the eyelid opening and closing. Accordingly, other simulation effects are needed to make the eyes more lifelike.
Therefore, what is needed is a simulated eye capable of replicating human eye behavior.

The driving mechanism 20 includes a circular baseboard 21, an electromagnet 23, and a magnetic body 25 corresponding to the electromagnet 23. The baseboard 21 defines two fixing holes 211. Two fasteners (such as screws, not shown) engage the two fixing posts 11 after passing through the two fixing holes 211 correspondingly to fasten the baseboard 21 to the eyeball 10. The electromagnet 23 is mounted on one side of the baseboard 21 facing the eyeball 10, and the electromagnet 23 is disposed between the two fixing holes 211. The magnetic body 25 has a portion 251 tapered away from the electromagnet 23.
The resilient film 40 includes a circular pupil portion 41 and an annular iris portion 42 surrounding the pupil portion 41. The pupil portion 41 is in a first color. The iris portion 42 is in a second color other than the first color.
The transmission mechanism 30 includes a plurality of transmission members 31. The transmission members 31 are also arranged in a radial manner and partially received in the corresponding guiding slots 151. Each transmission member 31 includes a transmission component 311 and an elastic component 315.
Each transmission component 311 includes a first portion 315 partially received in the guide slot 151 and a second portion 317 substantially perpendicular to the first portion 315. The first portions 315 are in radial arrangement. The second portions 317 are parallel and disposed between the first portion 315 and the magnetic body 25. Each second portion 317 has an inclined surface 318 away from the first portion 315. The inclined surfaces 318 combine to form a tapered opening 319 receiving the tapered portion 251 of the magnetic body 25.
Each elastic component 313 may be a spring received in the corresponding guide slot 151. Opposite ends of the elastic component 313 are connected to one end of the first portion 315 away from the second portion 317 and an outside edge of the iris portion 42 respectively.
In use, the electromagnet 23 is electrified to generate a repellant force between the electromagnet 23 and the magnetic body 25, and the tapered portion 251 of the magnetic body 25 linearly enters the opening 319, and moves the transmission components 311 radially away from their original positions via the repellant force. The elastic components 313 move and stretch the resilient film 40 from an original size, such that dilation of the pupil portion 41 is replicated. At the same time, the elastic components 313 are compressed to generate restoring force.
When the electromagnet 23 is electrified to generate an attractive force between the electromagnet 23 and the magnetic body 25, the tapered portion 251 of the magnetic body 25 linearly withdraws from the opening 319 via the attractive force. The elastic components 313 return the transmission components 311 to their corresponding original positions via the restoring force. Thus, the pupil portion 41 is restored to the original size so contraction of the pupil portion 41 is replicated.
It is to be understood, however, that even though information and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the present embodiments, the disclosure is illustrative only; and that changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
