The outer shell is arranged with a first electromagnetic member and a second electromagnetic member. The eyeball is arranged with a magnetic member. The first electromagnetic member and the second electromagnetic member are deactivated for simulating a normal state of the electromechanical eye. Either the first electromagnetic member or the second electromagnetic member is activated to generate a magnetic force for moving the eyeball, so as to simulate a vivid state of the electromechanical eye.

Description

BACKGROUND

1. Technical Field
The present disclosure relates to toys, and more particularly to an electromechanical eye for a toy.
2. Description of Related Art
Most toys include mechanical eyes. However, the range of movement and control of the mechanical eyes are limited, thus a child playing with the toy may quickly lose interest in the toy. Therefore, it is desired to overcome the described shortcomings and deficiencies.

The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

FIG. 1 is a front perspective view of an electromechanical eye in accordance with an exemplary embodiment.

DETAILED DESCRIPTION

Referring to FIG. 1, an electromechanical eye 10 is illustrated in accordance with an exemplary embodiment. The electromechanical eye 10 may be used in toys, such as a teddy bear or a doll. As illustrated, the electromechanical eye 10 generally includes an outer shell 100 and an eyeball 200. The outer shell 100 can be considered as an eyelid. The eyelid 100 defines a first or front opening 102. The eyeball 200 is movably or rotatably received in the eyelid 100. The eyeball 200 defines an iris 202. The color of the iris 202 may be black. As illustrated, the iris 202 of the eyeball 200 is located in the first opening 102, for simulating a normal state of the electromechanical eye 10. As used herein, “normal state” may refer to the iris 202 exposed, seen, and/or viewable. The electromechanical eye 10 may also be operated at a vivid state, which will be described hereinafter. As used herein, “vivid state” may refer to the state when the eyeball 200 is rotated with respect to the eyelid 100, such that the iris 202 moves to simulate a real eye. For example, the iris 202 may be partially hidden in the eyelid 100 and partially viewable from the first opening 102.
Also referring to FIG. 2, a rear view of the electromechanical eye 10 in accordance with an exemplary embodiment is illustrated. The eyelid 100 further defines a second or rear opening 106 opposite to the first opening 102. Adjacent to the second opening 106, a plurality of electromagnetic members 104 on an outside of the eyelid 100 is provided. The plurality of electromagnetic members 104 are arranged around the second opening 106, and are symmetrically distributed with respect to the second opening 106 in a circular manner.
The eyeball 200 is provided with a plurality of magnetic members 204. The plurality of magnetic members 204 is symmetrically distributed on an out surface of the eyeball 200 and also in a circular manner. Each of the plurality of magnetic members 204 is disposed corresponding to each of the plurality of electromagnetic members 104. In one implementation, the plurality of magnetic members 204 may be made of magnetizable metal, such as iron, cobalt, and nickel. In other implementation, the plurality of magnetic members 204 may be magnets. Each of the plurality of magnetic members 204 may be acted by an attractive magnetic force generated by activating a corresponding electromagnetic member 104.
Further referring to FIG. 3, an exploded view of the electromechanical eye 10 of FIGS. 1 and 2 is illustrated in accordance with an exemplary embodiment. As illustrated, the eyelid 100 of the electromechanical eye 10 includes a first shell 110 and a second shell 120. The first shell 110 and the second shell 120 may be assembled together by known mechanisms, such as hooks, latches, and/or screws. Because the first shell 110 and a second shell 120 can be detached or separated, the eyeball 200 may be easily placed in the eyelid 100 in assembly. Although the eyelid 100 is shown to be formed with two parts, in other implementations, the eyelid 100 may be integrally formed by one part.
As illustrated, the first shell 110 and the second shell 120 cooperatively define a first slot 108 at an inner side 150 of the first shell 110 and the second shell 120. The first slot 108 generally has a circular shape. The eyeball 200 defines a second slot 206 around an out surface of the eyeball 200. The second slot 206 also has a circular shape.
As illustrated, the electromechanical eye 10 further includes a spring 300. The spring 300 is engageably coupled to the eyelid 100 and the eyeball 200. The spring 300 includes an outer coil 302 and an inner coil 304. The outer coil 302 and the inner coil 304 are circular shaped and are concentric. The outer coil 302 and the inner coil 304 are connected together end by end, thereby a single piece element is formed. The outer coil 302 is engageably receivable in the first slot 108. The inner coil 304 is engageably receivable in the second slot 206.
When the electromechanical eye 10 is assembled, the simulate eye 10 may be operated to simulate a normal state and a vivid state.
At the normal state, the plurality of electromagnetic members 104 is deactivated. As used herein, “deactivated” may refer to the plurality of electromagnetic members 104 not supplied with electric power, that is, no magnetic force is generated between the plurality of electromagnetic members 104 and the plurality of magnetic members 204. Because there is no magnetic force, the eyeball 200 is at a first position with respect to the eyelid 100 by the spring 300. At the first position, the iris 202 of the eyeball 200 is exposed out of the first/front opening 102.
When one of the plurality of electromagnetic members 104 is selectively activated, an attractive magnetic force is generated between the activated electromagnetic member 104 and a corresponding magnetic member 204. As used herein, “activated” may refer to one of the plurality of electromagnetic members 104 being supplied with electric power. When the magnetic member 204 is applied with the attractive magnetic force, the eyeball 200 and the magnetic member 204 rotate together accordingly. At the same time, the spring 300 becomes resiliently deformed to generate an elastic force. The magnetic force is balanced with the elastic force, so as to position the eyeball 200 at a second position with respect to the eyelid 100. At the second position, the electromechanical eye 10 is in the vivid state. When the activated electromagnetic member is no longer activated, the attractive magnetic force is released, thereby the eyeball 200 returns to the first position by the elastic force of the spring 300.
In another operation, another electromagnetic member 104 other than the electromagnetic member 104 describe above may be selectively activated, and the eyeball 200 may be moved from the normal state or the first position to the vivid state or the second position from a different direction.
As described above, the electromechanical eye 10 may be operated to simulate an normal state and a vivid state by selectively activating the plurality of electromagnetic members 104. Therefore, the electromechanical eye 10 may appear vivid to the users such as kids.
Certain terminology is used herein for the convenience of the reader only and is not to be taken as a limitation on the scope of the disclosure. For example, words such as “above”, “below”, “upward”, “downward”, “horizontal”, “vertical”, and the like merely describe the configuration shown in the Figures. The element or elements of any embodiment of the present disclosure may be oriented in any direction, and the terminology, therefore, should be understood as encompassing such variations unless otherwise specified.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
For example, in other implementations, the plurality of electromagnetic members 104 may be provided on the outer surface of the eyeball 200. Correspondingly, the plurality of magnetic members 204 may be provided on the outside of the eyelid 100, and are disposed adjacent to the second opening 106.
