Description

Technical Field

[0001] This utility model relates to the field of bionic toy technology, specifically to an eyeball bionic mechanism. Background Technology

[0002] The current toy industry is moving from traditional static models towards intelligent, interactive, and highly biomimetic designs. In particular, biomimetic toys with realistic appearances and vivid movements (such as biomimetic dolls) are increasingly favored by the market. Among the many characteristics of biomimetic toys, the expressiveness of the eyes is crucial. A pair of eyes that can move flexibly, open and close, blink, and convey emotions is key to giving a toy a "soul." In related technologies, to achieve the blinking function of biomimetic toys, a commonly used technical solution is a separate eyeball structure. That is, the eyeball and the eyelids that drive its up-and-down blinking are two independent moving parts. The blinking action is achieved through the opening and closing movement of the upper and lower eyelids. For example, in patent document CN207101879U, the action of opening and closing the eyes is achieved by driving the upper and lower eyelids to move up and down.

[0003] Therefore, since the eyeball and eyelid are separate, there is an unavoidable assembly gap between them. After the eyelid closes, the eyeball is usually still in its normal working position. This causes the user to see some of the internal structures of the toy through the gap between the eyelids or the gap between the eyelid and the eyeball when looking from certain angles, whether from the front or the side. This creates a "hollow" effect, which destroys the overall aesthetics and biomimicry of the toy. Furthermore, for eyeballs with light sources, the assembly gap can also easily cause light leakage. Utility Model Content

[0004] This invention aims to at least partially solve the technical problems in related technologies where the eyeball and eyelid are separate, with an unavoidable assembly gap between them. After the eyelid closes, the eyeball is usually still in its normal working position, causing the user to see some internal structures of the toy through the gap between the eyelids or the gap between the eyelid and the eyeball when observing from certain angles from the front or side. This creates a "hollow" effect, which destroys the overall aesthetics and biomimicry of the toy. Furthermore, for eyeballs with light sources, the assembly gap can easily cause light leakage.

[0005] Therefore, one objective of this utility model is to provide an eyeball bionic mechanism for use in bionic toys with eye hole areas, comprising:

[0006] An eyeball mechanism, comprising an integrated eyeball lens, a display screen, and an eyelid, wherein the display screen is fixed to the inner side of the eyeball lens, and the eyelid is disposed on the eyeball lens and can rotate synchronously with the eyeball lens; when the eyeball lens is driven, the eyelid and the display screen rotate synchronously with the eyeball lens, and when the eyeball lens deviates from the eye hole area, the eyelid covers the eye hole area;

[0013] Preferably, the eyelid has an arc-shaped push-receiving portion that is fitted with the push-receiving portion, the arc-shaped push-receiving portion being attached to the circumferential surface of the second shaft portion and abutting against the push-receiving portion.

[0014] Preferably, the outer side of the lens body has a first arc surface and a second arc surface, the radial dimension of the first arc surface is greater than the radial dimension of the second arc surface, and the eyelid is attached and fixed to the second arc surface.

[0015] Preferably, the inner side of the lens body is provided with a positioning and mounting part, and a fixing frame is provided on the positioning and mounting part. The fixing frame and the lens body together fix the display screen so that the display screen fits against the inner side of the lens body.

[0027] The bionic eye mechanism provided by this utility model is mainly used in bionic toys with eye hole areas. By assembling the eye lens, display screen and eyelid into one unit, when the drive component drives the eye lens to rotate, the eye lens, display screen and eyelid can rotate synchronously.

[0046] The bionic eye mechanism of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0047] Reference Figure 1As shown, the bionic eye mechanism provided in this embodiment of the present invention is applied in a bionic toy with an eye hole area 31, including: an eye mechanism 10 and a drive component 20. The bionic toy typically includes a toy body 30. The eye mechanism 10 and the drive component 20 can be accommodated in the toy body 30. The drive component 20 is connected to the eye mechanism 10 in a transmission manner so as to drive the eye mechanism 10 to rotate in the toy body 30.

[0048] Combination Figure 2 , Figure 4 and Figure 5 As shown, the eyeball mechanism 10 includes an integrated eyeball lens 11, a display screen 12, and an eyelid 13. The display screen 12 is fixed to the inner side of the eyeball lens 11. The eyelid 13 is in close contact with the eyeball lens 11 and can rotate synchronously with the eyeball lens 11. When the eyeball lens 11 is driven, the eyelid 13 and the display screen 12 rotate synchronously with the eyeball lens 11. The eyeball lens 11 can be deflected into the eye socket region 31 to switch to an open eye state, or deflected away from the eye socket region 31 to achieve a closed eye state. When the eyeball lens 11 deviates from the eye socket region 31, the eye... The eyelid 13 covers the eye hole area 31, and the eyelid 13 can be attached to the inner side of the toy body 30 to avoid the formation of a gap between the eyelid 13 and the toy body 30. Preferably, the display screen 12 can be an LED screen, and it is set tightly against the inner side of the eye lens 11 so that when the display screen 12 outputs light outward through the eye lens 11, light leakage between the display screen and the eye lens is avoided. At the same time, with the eyelid 13 and the eye lens 11 tightly attached, the overall eyeball can be more vivid and the visual display is more natural.

[0049] Specifically, the eyeball lens 11 includes: two lens bodies 111, a first axis portion 113, a second axis portion 114, and a pushing portion 115. The two lens bodies 111 are connected as one unit by a connecting portion 112. The two lens bodies 111 respectively form two eyeballs. Each lens body 111 is provided with a display screen 12 and an eyelid 13. The first axis portion 113 is located between the two lens bodies 111 and is connected to the driving assembly 20. The second axis portion 114 is respectively located on both sides of the length direction of the two lens bodies 111. The first axis portion 113 and the second axis portion 114 are on the same axis, so that the lens body 111 can rotate around the first axis portion 113. The second shaft portion 114 is rotated. The push portion 115 is provided on the circumferential surface of the second shaft portion 114 and protrudes in the radial direction of the second shaft portion 114. The push portion 115 can be an arc-shaped structure. The eyelid 13 has an arc-shaped push portion 131 that is fitted with the push portion 115. The arc-shaped push portion 131 fits against the circumferential surface of the second shaft portion 114 and abuts against the push portion 115. The arc-shaped push portion 131 and the push portion 115 can be fitted together to form a ring structure. When the lens body 111 is driven, the push portion 115 rotates with the lens body 111 and can push the arc-shaped push portion 131 to rotate, thereby driving the eyelid 13 to rotate synchronously.

[0050] Furthermore, each lens body 111 has a first arc surface 116 and a second arc surface 117 on its outer side. The radial dimension of the first arc surface 116 is larger than that of the second arc surface 117, so that the first arc surface 116 and the second arc surface 117 form a height difference in the radial direction. This allows the eyelid 13 to be fixed to the second arc surface 117 after assembly with the eyeball lens 11, resulting in a higher fit between the eyelid 13 and the eyeball lens 11 and a smaller gap after assembly.

[0051] Reference Figure 2 , Figure 6 and Figure 7 As shown, each lens body 111 has a positioning mounting part 118 on its inner side. The positioning mounting part 118 is provided with a fixing frame 14. The fixing frame 14 and the lens body 111 together fix the display screen 12. The fixing frame 14 has a locking sleeve 141. The locking sleeve 141 is correspondingly provided with the positioning mounting part 118. The positioning mounting part 118 can be inserted into the locking sleeve 141. The locking sleeve 141 and the positioning mounting part 118 can be locked and fixed with screws, so that the fixing frame 14 and the eye lens 11 can be used to accommodate and fix the display screen 12 into a whole. The display screen 12 can be attached to the inner side of the lens body 111. When the eye lens 11 is deflected, the display screen 12 and the fixing frame 14 can rotate together with the eye lens 11 to achieve the effect of opening and closing the eyes. The display screen 12 can be deviated from the eye hole area 31 in the closed state and avoid light leakage.

[0052] Reference Figure 3 , Figures 6 to 8 As shown, the drive assembly 20 includes: a mounting frame 21, a drive motor 22, and a gear set 23. The eyeball mechanism 10 is rotatably mounted on the mounting frame 21. The drive motor 22 is mounted on the mounting frame 21. The mounting frame 21 is provided with a connecting shaft 211. The central shafts of the first shaft 113, the second shaft 114, and the sector gear 232 are coaxially arranged with the connecting shaft 211. A rotating shaft can be provided on the connecting shaft 211 so that the central shafts of the first shaft 113, the second shaft 114, and the sector gear 232 can be rotatably connected to the mounting frame 21, so that the eyeball lens 11 can rotate relative to the mounting frame 21 when rotating, and synchronously drive the eyelid 13 and the display screen 12 to rotate.

[0053] Furthermore, the gear set 23 is mounted on the mounting bracket 21. The gear set 23 includes a drive gear 231 and a sector gear 232. The drive gear 231 is mounted on the motor shaft of the drive motor 22. The sector gear 232 meshes with the drive gear 231 and is connected to the first shaft 113 via a central shaft. The central shaft of the sector gear 232 can be fixedly connected to the first shaft 113, so that when the sector gear 232 is driven by the drive gear 231, the sector gear 232 can drive the first shaft 113 to rotate. When the first shaft 113 rotates, it can drive the eyeball lens 11, the display screen 12, and the eyelid 13 to rotate synchronously. It can be understood that by using the sector gear 232 for transmission, the rotation of the eyeball mechanism 10 can be limited to the angle range of the sector gear 232, so that the rotation stroke of the eyeball mechanism 10 can be limited by the sector gear 232, avoiding damage caused by excessive stroke.

[0054] Optionally, a torsion spring 15 is fitted on the first shaft portion 113. One end of the torsion spring 15 abuts against the connecting portion 112, and the other end abuts against the mounting bracket 21. The torsion spring 15 can apply its own torque to the connecting portion 112 and the mounting bracket 21, so that when the eyeball mechanism 10 rotates, the torsion spring 15 can push the eyeball mechanism 10 back to the open eye state through its own torque, or it can also push the eyeball mechanism 10 back to the open eye state through its own torque. Thus, the torsion spring 15 can both reset the eyeball mechanism 10 and provide a certain buffering effect.

[0055] The bionic eye mechanism provided by this utility model is mainly used in bionic toys with an eye hole area 31. By assembling the eye lens 11, the display screen 12 and the eyelid 13 into one unit, when the driving component 20 drives the eye lens 11 to rotate, the eye lens 11, the display screen 12 and the eyelid 13 can rotate synchronously. When the eye lens 11 deviates from the eye hole area 31, the eyelid 13 can cover the eye hole area 31, preventing the user from seeing some of the internal structures of the toy through the eye hole area 31. This avoids the "hollow" effect and enhances the aesthetics of the bionic toy after the eyes are closed. Furthermore, the eyelid 13 covering the eye hole area 31 also prevents light from leaking from the display screen 12 through the assembly gap.
