Simulated eye for toy

Abstract

A simulated eye is capable of being changeable in an opened state and a closed state. The simulated eye includes an eyeball, an upper eyelid covering the eyeball, a pivot rod, and a driving device having a shaft. The pivot rod is pivotally coupled to the eyeball, the eyelid is fixed to the pivot rod, and the pivot rod is engaged with the shaft and is driven to rotate by the driving device. Accordingly, the upper eyelid is driven to rotate relative to the eyeball by the driving device, so as to simulate an opened state and a closed state of human eyes.

1 . A simulated eye, comprising:
 an eyeball;   an upper eyelid covering the eyeball;   a pivot rod; and   a driving device having a shaft;   wherein the pivot rod is pivotally coupled to the eyeball, the upper eyelid is fixed to the pivot rod, the pivot rod is engaged with the shaft and is driven to rotate by the driving device.   
   
   
       2 . The simulated eye as described in  claim 1 , wherein two fixing members protrude form the upper eyelid, a round hole is defined in each fixing member, and the pivot rod is fixed to the upper eyelid via the two round holes. 
   
   
       3 . The simulated eye as described in  claim 2 , wherein two bearings opposite to each other are symmetrically mounted on the eyeball, the two bearings are disposed corresponding to the two fixing members and are aligned in a straight line extending through a center of the eyeball, the pivot rod is pivotally coupled to the eyeball via the two bearings. 
   
   
       4 . The simulated eye as described in  claim 1 , wherein a gear is fixed to the pivot rod, the shaft comprises a plurality of teeth, and the shaft is meshed with the gear via the plurality of teeth. 
   
   
       5 . The simulated eye as described in  claim 4 , wherein a supporting member protrudes inwardly from an inner surface of the eyeball to support the shaft, the supporting member is opposite to the gear, the shaft is sandwiched between the supporting member and the gear. 
   
   
       6 . The simulated eye as described in  claim 1 , wherein the shaft is made from magnetic material and is movable relative to the driving device, the driving device comprises a coil, the shaft is driven to move inwardly when the coil being powered on. 
   
   
       7 . The simulated eye as described in  claim 6 , wherein at least one elastic element is fixed in the coil, the at least one elastic element is further coupled to the shaft, the at least one elastic element is pressed by the shaft while the coil being powered on and elastically deformed, and the at least one elastic element restores to drive the shaft return to an original position while the coil being powered off. 
   
   
       8 . The simulated eye as described in  claim 1 , further comprising a lower eyelid, the lower eyelid is attached to the eyeball. 
   
   
       9 . The simulated eye as described in  claim 1 , wherein the driving device is a step motor or a servo motor, the driving device drives the upper eyelid to shield and expose the eyeball. 
   
   
       10 . A simulated eye capable of being operated to change between an opened state and a closed state, the simulated eye comprising:
 an eyeball disposed with an iris;   an eyelid coverable on the eyeball; and   a driving device coupled to the eyelid for driving the eyelid to rotate relative to the eyeball;   wherein when the eyelid is driven by the driving device to rotate relative to the eyeball to the closed state, the iris of the eyeball is substantially hidden by the eyelid, and when the eyelid is driven by the driving device to rotate relative to the eyeball to the opened state, the iris of the eyeball is exposed and viewable.   
   
   
       11 . The simulated eye as described in  claim 10 , further comprising a rack and a gear engaged with the rack, the rack being coupled to the driving device, the gear being fixed to the eyelid, the driving device is capable of driving the rack to move linearly, the gear is caused to rotate by engaging with the rack, thereby the eyelid is caused to rotate accordingly.
