To achieve the above object, the present disclosure provides the following technical solutions:

4. The embodiment of the present disclosure proposes an eyeball bionic mechanism, which includes: an eyeball mounting frame; a pair of simulated eyeball modules, wherein the simulated eyeball module includes a simulated eyeball, a ball, a cage and a cardan shaft frame, and the cardan shaft frame is fixedly connected For the eyeball mounting frame, the retainer is arranged in the universal shaft frame, and the retainer is provided with an accommodating hole for accommodating the ball, a part of the ball is located in the accommodating hole, and the artificial eyeball is held on the retainer by the ball, and the artificial eyeball is provided with an accommodating hole. A linkage shaft; a synchronizing mechanism, the synchronizing mechanism is connected with the linkage shaft to drive a pair of simulated eyeballs to rotate up and down and/or left and right.

5. According to an eyeball bionic mechanism according to an embodiment of the present disclosure, the simulated eyeball module includes a simulated eyeball, a ball, a cage, and a universal shaft frame, the universal shaft frame is fixedly connected to the eyeball mounting frame, and the cage is arranged on the universal shaft. Inside the frame, the cage is provided with an accommodating hole for accommodating the ball, a part of the ball is located in the accommodating hole, the artificial eyeball is held on the cage by the ball, and the artificial eyeball is provided with a linkage shaft; the synchronizing mechanism, the synchronizing mechanism is connected with the linkage shaft , to drive a pair of simulated eyeballs to rotate up and down and/or left and right. In the embodiment of the present disclosure, a pair of artificial eyeball modules are fixed on the eyeball mounting frame. The artificial eyeball module confines the artificial eyeball in the cardan shaft frame through a cardan shaft frame, a cage and a ball, and the artificial eyeball can be placed in the cardan shaft frame. The cardan shaft is flexibly rotated in the frame, so as to maximize the area beyond the contact surface between the protruding eyeball and the eyeball mounting frame, so that the viewing angle of the simulated eyeball has a larger range of motion. The embodiment of the present disclosure is provided on the simulated eyeball. There is a linkage shaft, and the synchronization mechanism is connected with the linkage shaft to drive a pair of artificial eyeballs to rotate up and down and/or left and right. It can be seen that in the embodiment of the present disclosure, the linkage shaft on the artificial eyeball is used as a control point for controlling the artificial eyeball. Therefore, the spatial distance other than the contact surface between the human head skin and the eyeball mounting frame is not affected by the rotation axis, and it is ensured that there are enough parts of the simulated eyeballs that can be accommodated in the eye sockets of the simulated human head.

6. In addition, according to an embodiment of the present disclosure, it may also have the following additional technical features:

7. In some embodiments of the present disclosure, the synchronizing mechanism includes: a synchronizing rod, an upper and lower swing arm wheel, and a left and right swing arm wheel, both ends of the synchronizing rod are rotatably connected to the linkage shaft, so The upper and lower swing arm wheels are rotatably connected to the eyeball mounting frame, one end of the left and right swing arm wheels is rotatably connected to the upper and lower swing arm wheels, and the left and right swing arm wheels are rotatable. connected to the synchronous pull rod.

8. In some embodiments of the present disclosure, the cardan shaft frame includes a cardan shaft front frame and a cardan shaft rear frame that are connected to each other, and both the cardan shaft front frame and the cardan shaft rear frame are A retaining ring for limiting the position of the cage is provided.

9. In some embodiments of the present disclosure, the inner wall of the cage and the outer wall of the cage are concentric arc surfaces, and the accommodating holes are symmetrically distributed on both sides of the central section of the cage.

10. In some embodiments of the present disclosure, the artificial eyeball is further provided with a short arm, the linkage shaft is connected to the artificial eyeball through the short arm, and both ends of the synchronizing rod are provided with a first A shaft hole, the linkage shaft is provided with a first through hole, a screw passes through one of the first shaft hole and the first first through hole to connect the synchronizing rod and the linkage shaft, and the other screw The synchronizing rod and the linkage shaft are connected through the other first shaft hole and the second first through hole, and the synchronizing rod can rotate flexibly relative to the linkage shaft after being fixed.

11. In some embodiments of the present disclosure, the eyeball mounting frame is provided with two axle hole seats, and the axle hole seats are each provided with a second axle hole and the centerlines of the two second axle holes. Passing through the spherical center of the artificial eyeball, two second through holes are arranged on the upper and lower swing arm wheels, and a screw passes through one of the second shaft holes and one of the second through holes and the other screw passes through The other second shaft hole and the other second through hole are connected to the up and down swing arm wheel and the eyeball mounting bracket, and after being fixed, the up and down swing arm wheel can flexibly rotate relative to the eyeball mounting bracket 

12. In some embodiments of the present disclosure, the upper and lower swing arm wheels are provided with a third axle hole at the center of the two second axle holes, and the left and right swing arm wheels are provided with a fourth axle hole, The screws pass through the third shaft hole and the fourth shaft hole to connect the upper and lower swing arm wheels and the left and right swing arm wheels, and the fixed left and right swing arm wheels are movable relative to the up and down swing arm wheels. Flexible rotation.
