Description

BACKGROUND

1. Technical Field

The present disclosure relates to mechanical eyes, and particularly, to a mechanical eye for an electronic pet.

2. Description of the Related Art

Nowadays, electronic pets are becoming popular. Electronic pets are being designed with evermore functions that can provide intelligent interaction with their owners. Life-like interaction with the pets is one of the most important characteristic that attracts the attention and holds the interest of consumers. Because the eyes, of the electronic pet, play an important rule in making the electronic pet seems more life-like, it is essential that the eyes have life-like movement. However, the eyes of most existing electronic pets cannot blink like those of their real-life counterparts.

Therefore, the need exist for an eye for an electronic pet that can automatically blink like those of a real-life counterpart.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1-2, an eye 100 for an electronic pet according to an exemplary embodiment is shown. The eye 100 includes an eyelid 110, an eyeball 120, a driving box 130, and a driving source 140. The eyelid 110 is rotatably attached to an outside surface of the eyeball 120. The eyeball 120 defines a receiving room 120a in which the driving box 130 and the driving source 140 are jointly received therein. The driving box 130 connects to the eyelid 110 and is capable of driving the eyelid 110 to rotate along the outside surface of the eyeball 120, to imbue the eye 100 with the ability to blink. The driving source 140 is mounted on the driving box 130 and configured to supply rotary power to the driving box 130 to rotate the eyelid 110. The driving box 130 and the driving source 140 collectively construct a driving device to rotate the eyelid 110.

Referring to FIGS. 2-4, the eyelid 110 includes a substantially hemispherical shell 112. The shell 112 includes a substantially annular end 112a and two substantially semicircular protuberances 114 symmetrically protruded from the annular end 112a along the extending direction of the spherical surface of the shell 112. Two trunnions 116 are separately formed on an inside surface of protuberances 114, and each trunnion 116 is substantially perpendicular to the corresponding protuberance 114. At least one trunnion 116 defines a terminal shaft hole 118 therein for receiving a driving element.

The eyeball 120 includes an upper carapace 122, and a lower carapace 124. A number of locating sets 123 and corresponding number of the locating columns 125 are respectively formed on the inside walls of the lower and upper carapaces 122, 124. The locating sets 123 and the locating columns 125 can engage with each other for connecting the upper carapace 122 to the lower carapace 124.

The upper carapace 122 includes a front shell 122a and a separate back shell 122b. Because the front shell 122a and the back shell 122b are separate structures, they can be assembled to the lower carapace 124 easily and accurately. The front shell 122a includes a substantially annular edge 122c, and two concave cutouts 126 formed on the annular edge 122c corresponding to and receiving the trunnions 116 of the eyelid 110. The back shell 122b is shaped substantially one-third of a sphere, and includes two separate and parallel upper handles 127 protruded outward from an outside surface of the back shell 122b.

The lower carapace 124 includes lower annular end 124a, and two concave semicircle openings 129 formed on the lower annular end 124a and corresponding to the cutouts 126 formed on the upper carapace 122. The openings 129 of the lower carapace 124 and the cutouts 126 of the upper carapace 122 corporately form two through holes which are used for the trunnions 116 extending therethrough to connect to the eyelid 110. Two supporting poles 128 are separately formed on the inner side of the lower carapace 124 and are configured for supporting and fixing the driving box 130. Corresponding to the upper handles 127 of the upper carapace 122, two parallel lower handles 121 are separately formed on the outer side of the lower carapace 124 to assembly with the upper handles 127 together for constructing a connecting end which is configured for connecting the eye to an electronic pet.

The driving box 130 includes a housing 132, a number of middle shafts 133, a number of gears 137 and a terminal shaft 134. The housing 132 defines a receiving room for receiving the middle shafts 133, the gears 137 and the terminal shaft 134. The middle shafts 133 and the terminal shaft 134 are respectively matched with the hub portions of the gears 137 and are rotatably mounted in the housing 132, so that the middle shafts 133, the terminal shaft 134 and the gears 137 can rotate synchronously. One end of the terminal shaft 134 protrudes from the housing 132 and engages with the terminal shaft hole 118 of the eyelid 110 for connecting to the eyelid 110. The housing 132 includes a number of interconnected side walls 132a, two locating bumps 135 separately formed on an outer sides of the side walls 132a corresponding to the supporting poles 128 of the lower carapace 124. Each locating bump 135 defines a through hole 136 thereon for a blot 139 passing there through to fix the driving box 130 in the eyeball 120. A stepped hole 138, communicating with the through hole 136 and having a larger diameter than the through hole 136, is defined on a side surface of the locating bump 135 corresponding to the supporting poles 128 of the lower carapace 124. The stepped hole 138 is configured for receiving supporting poles 128 therein, as a result, when the driving box 130 is fixed on the supporting poles 128, the inner-side wall of the stepped hole 138 can hold the supporting pole 128 stably to prevent the whole driving box 130 from shifting.

The driving source 140 is generally selected from one of a stepping motor or a piezoelectric motor mounted on the outer surface of side wall 132a of the housing 132 and configured for rotating the terminal shaft 134 of the driving box 130 to rotate the eyelid 110, from its original position, through a predetermined angle or reversely rotate the eyelid 110 to return the eyelid 110 to its original position. The driving source 140 can be controlled by a central controller (not shown) to control the rotation time and angle of the eyelid 110.

When the driving source 140 operates, the middle shafts 133 are rotated by the operating driving source 140, and the gears 137 mounted on the middle shafts 133 follow the rotation of the middle shafts. Accordingly, the terminal shaft 134 rotates following the rotation of the gears 137, as a result, the eyelid 110 connected to the terminal shaft 134 of the driving box 130 rotates, following the rotation of terminal shaft 134, first in one direction, then in the opposite direction when the driving source reverses itself. In this way, the eyelid 110 can rotate along the eye ball 120 to shade or expose the eye ball and to perform a life-like blinking action.

It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
