Compact bionic eye device based on two-degree-of-freedom electromagnetically-driven rotating mechanism

A compact bionic eye device based on a two-degree-of-freedom electromagnetically-driven rotating mechanism, being composed of a stator assembly and a rotor assembly, wherein the stator assembly comprises an outer spherical shell (2), stator cores (3), a stator connector (5), an angular displacement camera (6), a spherical hinge pressing block (9) and windings (10);

• and the rotor assembly comprises a camera (1), a rotor (4), a rotor connector (7), a spherical hinge (8) and a camera connector (11);
• four stator cores (3) are fixedly connected with the outer spherical shell (2) and uniformly distributed along the large circumference of the outer spherical shell (2);
• the stator connector (5) is located at the central position of the four stator cores (3) and used for connecting and fixing the four stator cores (3);
• the rotor connector (7), the spherical hinge (8) and the camera connector (11) form a transmission rod;
• the center of the spherical hinge (8) is concentric with the center of a central spherical surface of the rotor (4) and restrains the rotor assembly to rotate around a fixed-point, i.e., around the center of the central spherical surface of the rotor (4);
• the spherical hinge pressing block (9) and the stator connector (5) are arranged at both sides of spherical hinge (8), close to the camera and the rotor respectively;
• and in this way, a sphere pair is formed by the spherical hinge (8), the spherical hinge pressing block (9) and the stator connector (5).
