Artificial eye

Abstract

An artificial eye includes a frame, an eyeball, a pupil and a magnetic member. The frame defines a substantially spherical-shaped cavity and an opening communicating with the cavity. The eyeball is substantially spherical shaped and rotatably received in the cavity. The pupil is positioned on the eyeball and exposed to the outside of the frame through the opening. The magnetic member is positioned on the eyeball.

1 . An artificial eye, comprising:
 a frame defining a substantially spherical-shaped cavity and an opening communicating with the cavity;   a substantially spherical-shaped eyeball rotatably received in the cavity;   a pupil positioned on the eyeball and exposed to the outside of the frame through the opening; and   a first magnetic member positioned on the eyeball.   
   
   
       2 . The artificial eye of  claim 1 , wherein the first magnetic member is positioned opposite to the position of the pupil. 
   
   
       3 . The artificial eye of  claim 1 , wherein the first magnetic member is a permanent magnet. 
   
   
       4 . The artificial eye of  claim 1 , further comprising:
 a second magnetic member positioned outside of the frame and configured to attract the first magnetic member to arrange the pupil in an initial position; and   a plurality of third magnetic members positioned outside of the frame around the first magnetic member and configured to attract the first magnetic member to rotate the pupil away from the initial position.   
   
   
       5 . The artificial eye of  claim 4 , wherein the second magnetic member is a permanent magnet or an electromagnetic member. 
   
   
       6 . The artificial eye of  claim 4 , wherein the third magnetic members are electromagnetic members. 
   
   
       7 . The artificial eye of  claim 1 , wherein the pupil comprises a light source positioned therein. 
   
   
       8 . The artificial eye of  claim 7 , wherein the frame defines a through hole; the artificial eye further comprises a conductive wire passing through the through hole and electrically coupled to the light source. 
   
   
       9 . The artificial eye of  claim 1 , wherein the frame defines a plurality of recesses in an inner surface thereof, a plurality of ball bearings is positioned between the inner surface and the eyeball, and received in the recesses; the artificial eye further comprises a lubricant member positioned between the inner surface and the eyeball. 
   
   
       10 . The artificial eye of  claim 1 , wherein a diameter of the eyeball is larger than a width of the opening. 
   
   
       11 . A doll, comprising an artificial eye comprising:
 a frame defining a substantially spherical-shaped cavity and an opening communicating with the cavity;   a substantially spherical-shaped eyeball rotatably received in the cavity;   a pupil positioned on the eyeball and exposed to the outside of the frame through the opening;   a first magnetic member positioned on the eyeball;   a second magnetic member positioned outside of the frame and configured to attract the first magnetic member to arrange the pupil in an initial position; and   a plurality of third magnetic members positioned outside of the frame around the first magnetic member and configured to attract the first magnetic member to rotate the pupil away from the initial position.   
   
   
       12 . The doll of  claim 11 , wherein the first magnetic member is positioned opposite to the position of the pupil. 
   
   
       13 . The doll of  claim 11 , wherein the first and second magnetic members are permanent magnets. 
   
   
       14 . The doll of  claim 11 , wherein the third magnetic members are electromagnetic members. 
   
   
       15 . The doll of  claim 11 , wherein a diameter of the eyeball is larger than a width of the opening. 
   
   
       16 . A robot, comprising an artificial eye comprising:
 a frame defining a substantially spherical-shaped cavity and an opening communicating with the cavity;   a substantially spherical-shaped eyeball rotatably received in the cavity;   a pupil positioned on the eyeball and exposed to the outside of the frame through the opening;   a first magnetic member positioned on the eyeball;   a second magnetic member positioned outside of the frame and configured to attract the first magnetic member to arrange the pupil in an initial position; and   a plurality of third magnetic members positioned outside of the frame around the first magnetic member and configured to attract the first magnetic member to rotate the pupil away from the initial position.   
   
   
       17 . The robot of  claim 16 , wherein the first magnetic member is positioned opposite to the position of the pupil. 
   
   
       18 . The robot of  claim 16 , wherein the first and second magnetic members are permanent magnets. 
   
   
       19 . The robot of  claim 16 , wherein the third magnetic members are electromagnetic members. 
   
   
       20 . The robot of  claim 16 , wherein a diameter of the eyeball is larger than a width of the opening.
