The first driving mechanism comprises a first steering engine 51 fixedly connected to the mounting support 10, a steering engine support 52 and a transmission assembly 53. The first steering engine 51 is connected with the steering engine support 52 through the transmission component 53, and is used for driving the steering engine support 52 to rotate relative to the mounting support 10 in the Y-axis direction.

Specifically, the transmission assembly 53 includes a base 531, a cover plate 532 covering the base 531, and a gear transmission structure 533 disposed between the base 531 and the cover plate 532. The connecting shaft 521 is arranged on the steering engine bracket 52, and the connecting shaft 521 and the rotating shaft part of the first steering engine 51 are respectively connected with the gear transmission structure 533, so that when the first steering engine 51 of the embodiment works, the steering engine bracket 52 can be driven to rotate relative to the mounting support 10 in the Y-axis direction through the meshing fit between the gears on the gear transmission structure 533. It should be noted that the present embodiment is preferably a one-stage transmission gear structure including two gears, but the gear transmission structure 533 may be a multi-stage transmission gear structure according to the use requirement, and will not be described herein.

The second driving mechanism of this embodiment includes a second steering engine 61 fixedly connected to the steering engine bracket 52, and a driving plate 62 disposed on a rotating shaft portion of the second steering engine 61, so that when the first driving mechanism works, the second driving mechanism can be driven by the steering engine bracket 52 to rotate relative to the fixed support 10 in the Y-axis direction.

Correspondingly, the inner wall of the eyeball 20 is provided with a limiting slot 21 for accommodating the driving plate 62, and the second steering engine 61 can drive the eyeball 20 to rotate relative to the mounting support 10 in the X-axis direction through the abutting fit between the driving plate 62 and the slot wall of the limiting slot 21.

Furthermore, the eyeball 20 is provided with a fixing screw (not shown) at the position of the limiting slot 21, and the fixing screw penetrates through the driving plate 62 and is connected and fixed with the rotating shaft part of the second steering engine 61, so that the second steering engine 61, the driving plate 62 and the eyeball 20 are relatively fixed. It should be noted that, in this embodiment, the rotating shaft portion of the second steering engine 61 is not limited to be connected and fixed with the driving plate 62 and the eyeball 20 by the fixing screw, and a person skilled in the art can limit and fix the body of the second steering engine 61 on the eyeball 20 directly through a connecting piece according to the use requirement, and at the same time, the driving plate 62 is pressed by the body of the second steering engine 61 at the position of the limit slot 21 of the eyeball 20.

In this embodiment, the upper eyelid 30 has a first connecting element 31 and a second connecting element 32 respectively located on two opposite sides of the eyeball 20, the lower eyelid 40 has a third connecting element 41 and a fourth connecting element 42 respectively located on two opposite sides of the eyeball 20, the first connecting element 31 is matched with the third connecting element 41, the second connecting element 32 is matched with the fourth connecting element 42, specifically, a rotating shaft 340 is connected between the first connecting element 31 and the third connecting element 41 and/or between the second connecting element 41 and the fourth connecting element 42, and a torsion spring 430 is sleeved on the rotating shaft 340 to prop open the upper eyelid 30 and the lower eyelid 40. Preferably, a rotating shaft 340 is connected to each of the first connecting member 31 and the third connecting member 41, and the second connecting member 32 and the fourth connecting member 42, and the torsion spring 430 is provided as one. It should be noted that the two hook portions of the torsion spring 430 sleeved on the rotating shaft 340 respectively abut against the first connecting piece 31 and the third connecting piece 41, and the first connecting piece 31 and the third connecting piece 41 are spread by using the structure of the torsion spring 430, so as to spread the upper eye piece 30 and the lower eyelid 40.

That is, the spreading angle between the upper eyelid 30 and the lower eyelid 40 according to the present embodiment is limited by the contact between the upper limiting stop 342 of the rotation shaft 340 and the socket end surface of the upper arc groove 301 of the first connector 31 or the third connector 41.

The first connecting piece 31 and the third connecting piece 33, and/or the second connecting piece 32 and the fourth connecting piece 42 are connected with a first eyelid pressing plate 311 and a third eyelid pressing plate 411 respectively, preferably, the first eyelid pressing plate 311 and the third eyelid pressing plate 411 are connected on the second connecting piece 32 and the fourth connecting piece 42 respectively, and the third driving mechanism can push the first eyelid pressing plate 311 and the third eyelid pressing plate 411 for driving the upper eyelid 30 and the lower eyelid 40 to compress and compress the torsion spring 430 to be folded. It should be noted that the first eyelid pressing plate 311 and the third eyelid pressing plate 411 are disposed on the same plane and extend in two opposite directions, so that the third driving mechanism can simultaneously act on the first eyelid pressing plate 311 and the third eyelid pressing plate 411 during operation, and realize synchronous driving of the first connecting member 31 and the third connecting member 41, and further realize synchronous closing driving of the upper eyelid 30 and the lower eyelid 40.

It should be noted that the second connecting member 32 has the same structure as the first connecting member 31, the third connecting member 41 has the same structure as the fourth connecting member 42, and the principle of driving the second connecting member 32 and the fourth connecting member 42 to be opened and closed can be the same as the principle of driving the first connecting member 31 and the third connecting member 41 to be opened and closed, so as to realize the stability of the opening and closing movement of the upper eyelid 30 and the lower eyelid 40 relative to the eyeball 20. Of course, those skilled in the art can set the second connecting member 32 to have the same structure as the third connecting member 41 and the fourth connecting member 42 to have the same structure as the first connecting member 31 according to the use requirement.

As can be seen from the above, the first steering engine 51 and the second steering engine 61 for driving the eyeball 20 to rotate and the third steering engine 71 for driving the upper eyelid 30 and the lower eyelid 40 to blink in cooperation with the eyeball 20 are provided independently of each other, so that the artificial eyeball of the present embodiment can control the operations of the first steering engine 51, the second steering engine 61, and the third steering engine 71 according to the use requirements, and thus, when the artificial eyeball operates, the artificial eyeball can be effectively simulated, and the simulation degree of the whole artificial eyeball is high.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
