Simulated eye for toy

Abstract

A simulated eye is capable of being changed between a contracted state and a dilated state. The simulated eye includes a shell defining an opening, an eyeball, and a driving device. The eyeball is received in the shell and exposed at the opening, the eyeball includes a lens and a pupil, the pupil is visible through the lens, and a virtual image of the pupil formed via the lens. The driving device is configured to drive the pupil to move toward and backward the lens. When the transmission member drives the pupil to move, the virtual image of the pupil is changeable, and the simulated eye changed between a contracted state and a dilated state.

1 . A simulated eye, comprising:
 an eyeball comprising a lens and a pupil, wherein the pupil is visible though the lens; and   a driving device operatively coupled to the eyeball for driving the pupil to move toward and away from the lens.   
   
   
       2 . The simulated eye in  claim 1 , further comprising a shell for receiving the eyeball, an opening is defined in the shell, and the pupil being exposed via the opening through the lens. 
   
   
       3 . The simulated eye in  claim 1 , wherein the pupil is colored. 
   
   
       4 . The simulated eye as described in  claim 1 , wherein a hole is defined in the eyeball, the lens is fixed in the hole. 
   
   
       5 . The simulated eye as described in  claim 1 , wherein the lens is a convex lens having a center point and a focal point. 
   
   
       6 . The simulated eye as described in  claim 5 , wherein the pupil is disposed between the center point and the focal point. 
   
   
       7 . The simulated eye in  claim 1 , wherein a hollow cylindrical sleeve protrudes inwardly from an inner surface of the eyeball and surrounds the lens. 
   
   
       8 . The simulated eye in  claim 7 , wherein the driving device is slidable relative to the sleeve, and the driving device comprises a supporting member, a transmission member, and a motor, the supporting member is configured to fix the pupil and is movably coupled to the motor via the transmission member. 
   
   
       9 . The simulated eye as described in  claim 8 , wherein the supporting member comprises a round supporting sheet, the pupil is fixed on the supporting sheet, and the diameter of the supporting sheet is less than that of the sleeve. 
   
   
       10 . The simulated eye as described in  claim 8 , wherein the motor is a step-motor or a servomotor. 
   
   
       11 . The simulated eye as described in  claim 8 , wherein the transmission member comprises a plurality of threads, the supporting member further comprises a nut, and the supporting member is couple to the motor via the nut engaging with the transmission member. 
   
   
       12 . A simulated eye capable of being operated between a contracted state and a dilated state, the simulated eye comprising:
 a shell defining an opening;   an eyeball received in the shell and exposed via the opening, the eyeball comprising a lens and a pupil, the pupil being visible through the lens, and a virtual image of the pupil formed via the lens; and   a driving device for driving the pupil move toward and away from the lens;   wherein when the transmission member drives the pupil move, a size of a virtual image of the pupil formed by the lens is changeable, whereby the simulated eye is changed between the contracted state and the dilated state.   
   
   
       13 . The simulated eye in  claim 12 , wherein the lens is a convex lens having a center point, and a focal point, the pupil is disposed between the center point and the focal point. 
   
   
       14 . A simulated eye capable of capturing images, the simulated eye comprising:
 a shell defining an opening;   an eyeball received in the shell and exposed via the opening, the eyeball comprising a lens and a pupil structure comprising a camera, and the pupil structure being visible through the lens; and   a driving device for driving the camera move toward and away form the lens;   wherein when the camera is operated to capture images, the driving device adjusts optical parameters of the camera in association with the lens for capturing images by adjusting positions of the camera.
