[0019] Embodiment
[0020] Please refer to Figures 1-4 The present application provides the following technical scheme: a turning mechanism for bionic eye adjustment, comprising an eye frame 1, and an eyeball frame 6 installed inside the eye frame 1. The front end of the eyeball frame 6 is provided with a camera unit 2, and a frame opening 3 is formed at the center position of the front end of the eye frame 1. A support arm 4 is fixed to the inner wall of the rear end of the eye frame 1 to ensure the stability of the internal structure. The camera unit 2 protrudes out of the frame opening 3 to better capture external information. A first servo motor 5 is installed at one end of the support arm 4, and a base 7 is fixed to the output end of the first servo motor 5 to realize the rotation of the base 7 and further realize the left and right rotation of the eyeball frame 6. A rotating shaft 8 is rotatably connected to the top end of the base 7, and a second servo motor 9 is installed at one end of the rotating shaft 8 to ensure the control of the rotating shaft 8 and realize the up and down movement of the eyeball frame 6. The body of the second servo motor 9 is fixed to the top of the base 7, and a connecting rod 10 is fixed at the center of the shaft body of the rotating shaft 8. A pad 11 is fixed at one end of the connecting rod 10, and the pad 11 is fixed to the inner wall of the eyeball frame 6. The connecting rod 10 realizes the transmission connection between the movement mechanism and the eyeball frame 6, and the pad 11 increases the connection strength between the connecting rod 10 and the eyeball frame 6.
[0021] In order to facilitate the multi-angle rotation of the eyeball frame 6 without hindering the external eye frame 1, in the present embodiment, as a preferred technical scheme of the present application, the eye frame 1 comprises a positioning part 12 and a mounting part 13, the frame opening 3 is formed at the center of the mounting part 13, and the positioning part 12 is a hemispherical hollow structure; the eyeball frame 6 comprises a movable part 14 and a camera part 15, the camera unit 2 is installed inside the camera part 15, the movable part 14 is a hollow spherical cross-section body structure symmetrically cut on both sides, and the positioning part 12 and the movable part 14 are concentrically arranged.
[0022] In order to facilitate the fixation of the eyeball frame 6 to the eye frame 1, in the present embodiment, as a preferred technical scheme of the present application, the caliber of the frame opening 3 is smaller than the ball diameter of the movable part 14 and larger than the diameter of the end face of the camera part 15.
[0023] In order to protect the internal structure of the camera unit 2, in the present embodiment, as a preferred technical scheme of the present application, a transparent protective film 16 is arranged outside the camera part 15.
[0024] In summary, the technical scheme of the utility model needs to stably install the eye frame 1 on the orbital part of the robot skull, to ensure that it remains stable as the basic component of the bionic eye system. During use, the output of the first servo motor 5 drives the connecting rod 10 to rotate the eyeball frame 6 in the eye frame 1 in the left-right direction, with the help of the base 7 and the rotating shaft 8. At the same time, the output of the second servo motor 9 drives the rotating shaft 8 to rotate, so that the connecting rod 10 drives the eyeball frame 6 to rotate in the eye frame 1 in the up-down direction. When it is necessary to rotate the eyeball frame 6 in the left-up, left-down, right-up and right-down directions, it is only necessary to synchronously adjust the corresponding motion parameters of the two servo motors to achieve the rotation.
