Description
- 1. Technical Field
- The disclosure relates to toys and, more particularly, to a simulated eye for a toy.
- 2. Description of Related Art
- As the development of the electronic technology, more and more robot toys simulate people's actions, such as, walking, jumping, and so on. As known, eyes are one of the most important organs of human body, and people can express various feelings via the action of the eyes. The eyes of some robot toys simulate human eyes by imitating various shapes of the human eyes. However, some of these simulations are limited to the eyelids opening and closing, and accordingly, other simulation effects of the eyes of the robot toys are needed to make the robot looks more lifelike. Therefore, what is needed is a simulated eye capable of simulating more human eyes' actions.
- The components of the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments of the simulated eye. Moreover, in the drawings, like reference numerals designate corresponding parts throughout several views.

FIG. 8 is a perspective view of the pupil in a dilated state. - Referring to
FIG. 1 , a simulatedeye 10 includes aneyeball 100 and aspherical shell 200 for receiving theeyeball 100. Anopening 202 is defined in theshell 200. Aconvex lens 102 is disposed in theeyeball 100 and exposed via theopening 202. Apupil 300 is fixed in theeyeball 100 and is visible through theconvex lens 102, and an optical axis of theconvex lens 102 generally extends through a centre of thepupil 300. A portion of thepupil 300 facing theconvex lens 102 is colored. - Referring to
FIGS. 2 and 3 , a round throughhole 104 is defined in theeyeball 100. Theconvex lens 102 is mounted into the throughhole 104. A hollowcylindrical sleeve 106 protrudes from an inner surface of theeyeball 100 and surrounds the throughhole 104. Thesleeve 106 is configured for receiving a supportingmember 400. Acylindrical protrusion 108 protrudes inwardly from an inner surface of thesleeve 106. Theprotrusion 108 is parallel to an axis of thesleeve 106. - The simulated
eye 100 further includes the supportingmember 400 for supporting thepupil 300, atransmission member 500, and amotor 600 having amotor shaft 610. The supportingmember 400 is threadedly engaged with thetransmission member 500. Thetransmission member 500 is fixed on themotor shaft 610 of themotor 600. - The supporting
member 400 includes around supporting sheet 402, anut 404, and three supportingrods 406 for connecting thenut 404 to the supportingsheet 402. Thepupil 300 is fixed on a side of the supportingsheet 402 opposite to theconvex lens 102. A diameter of the supportingsheet 402 is a little less than that of thesleeve 106. Arecess 408 is defined in a rim of the supportingsheet 402. Therecess 408 engages with theprotrusion 108 to restrict the supportingmember 400 to rotate relative to thesleeve 106. The supportingmember 400 is slidable along the axis of thesleeve 106 when received in thesleeve 106. The supportingmember 400 is movably coupled to thetransmission member 500 via thenut 404. In particular, the three supportingrods 406 are arranged for converting the rotational force of thetransmission member 500 with respect to thenut 404 to a linear force to move thepupil 300 back and forth. - Therefore, the supporting
member 400 is driven by themotor 600 to move back and forth. As a result, thepupil 300 fixed on the supportingmember 400 is movable toward and away from theconvex lens 102. In the embodiment, thetransmission member 500 has a plurality of threads, and themotor 600 is a step-motor, or a servomotor. - Moreover, A
holding member 204 protrudes inwardly from an inner surface of theshell 200, and theholding member 204 defines a cavity (not shown) for holding themotor 600. Theconvex lens 102 includes two focal points F1 and F2, and a center point O. Thepupil 300 can be moved between the center point O and the focal point F2 thereof. - Referring to
FIG. 4 , in assembly, thepupil 300 is fixed on the supportingsheet 402, and the supportingmember 400 is received in thesleeve 106. Themotor 600 is held in theholding member 204, and the supportingmember 400 fixing thepupil 300 is coupled to themotor 600 via thenut 404 engaged with thetransmission member 500. After assembly, the center of theconvex lens 102, thepupil 300, and the supportingsheet 402 are aligned in a straight line extending along an axis of themotor shaft 610. - Referring to
FIGS. 5 and 6 , in a first state, thepupil 300 is located at a first position A adjacent to theconvex lens 102. The first position A is on the axis of theconvex lens 102 between the focal point F2 and the center point O. In the first state, a firstvirtual image 300 a of thepupil 300 is formed, and a size of the firstvirtual image 300 a is a little larger than that of theactual pupil 300 when observing thepupil 300 through theconvex lens 102. - Referring to
FIGS. 7 and 8 , in a second state, thepupil 300 is moved further away from theconvex lens 102 and is located at a second position B still between the focal point F2 and the center point O. In the second state, a secondvirtual image 300 b of thepupil 300 is formed, and a size of the secondvirtual image 300 b is larger than that of the firstvirtual image 300 a. Therefore, while thepupil 300 is moved from the first position A to the second position B, thepupil 300 looks dilated. - When the
pupil 300 is driven to move toward theconvex lens 102 gradually by themotor 600, thepupil 300 changes gradually from a dilated state to a contracted state. When thepupil 300 is driven to move away from theconvex lens 102, thepupil 300 changes gradually from a contracted state to a dilated sated. Thus, by driving thepupil 300 toward and away from theconvex lens 300, thepupil 102 appears to be dilating and contracting respectively. - Furthermore, the
pupil 300 can function as a camera, in the embodiment, thepupil 300 is a micro-camera almost similar to a human pupil. When thepupil 300 is used to capture images, optical parameters for capturing images can be adjusted via themotor 600 driving thepupil 300 in frontward and backward direction, so as to capture images with a better effect. - Although the present disclosure has been specifically described on the basis of the embodiments thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiments without departing from the scope and spirit of the disclosure.
