[0035] Reference Figures 1-10 A structure for controlling the movement of a doll's eyes using a coil includes a face shell 1 and a back shell 2, two eye holes 3 arranged side by side on the face shell 1, an eyeball 4 installed in each of the two eye holes 3, the two eyeballs 4 being connected by a first rotating shaft 5, the first rotating shaft 5 being rotatably mounted inside the face shell 1, a first magnet seat 6 being provided on the rear side of the middle part of the first rotating shaft 5, a first magnet 7 being installed in the first magnet seat 6, and a coil bracket 8 installed inside the face shell 1, a first coil seat 9 being provided on the coil bracket 8 located at the lower end of the first magnet seat 6, a first coil 10 being installed in the first coil seat 9 corresponding to the position of the first magnet 7, the first coil 10 being energized to move the first magnet 7 and to make the first rotating shaft 5 and the two eyeballs 4 rotate synchronously.

[0036] In use, turning on the power switch energizes the first coil 10, generating a magnetic field around it. By controlling the direction of the current in the first coil 10, the direction of the magnetic field can be changed, thus creating an attractive or repulsive force on the first magnet 7. If a repulsive force is applied to the first magnet 7, it moves upward, moving away from the first coil 10, while the first rotating shaft 5 and the two eyeballs 4 rotate downward simultaneously. If an attractive force is applied to the first magnet 7 or power to the first coil 10 is stopped, the first magnet 7 moves downward to its original position, while the first rotating shaft 5 and the two eyeballs 4 rotate upward to their original position, thus achieving a regular up-and-down rotation of the two eyeballs 4. When power to the first coil 10 is stopped, no magnetic field is generated around it, and the first magnet 7, the first rotating shaft 5, and the two eyeballs 4 automatically return to their original positions under their own weight. This application features a simple structure, is not easily damaged, has low cost, occupies little space, and can be used in smaller toys, thus having a wider range of applications.

[0037] In some embodiments, a mouth opening 11 is provided on the face shell 1, and a tongue plate 12 is installed inside the mouth opening 11. The front end of the tongue plate 12 is rotatably installed inside the face shell 1 via a second rotating shaft 13. A second magnet seat 14 is provided at the rear end of the tongue plate 12, and a second magnet 15 is installed inside the second magnet seat 14. A second coil seat 16 is provided on the coil support 8 located at the lower end of the second magnet seat 14, and a second coil 17 corresponding to the position of the second magnet 15 is installed inside the second coil seat 16. When the second coil 17 is energized, it can make the second magnet 15 and the tongue plate 12 move synchronously. The principle of controlling the tongue plate 12 to swing up and down is the same as the principle of the two eyeballs 4 to swing. With the above structure, not only can the two eyeballs 4 of the toy rotate, but the tongue plate 12 can also swing, making the toy more vivid and interesting.

[0038] In some embodiments, two rotating shaft plates 18 are arranged side by side in the shell 1 between the two eyeball holes 3. The two rotating shaft plates 18 extend along the length direction of the shell 1. A first rotating shaft groove 19 and a second rotating shaft groove 20 are arranged side by side on both rotating shaft plates 18. The two ends of the first rotating shaft 5 are rotatably placed into the two first rotating shaft grooves 19, and the two ends of the second rotating shaft 13 are rotatably placed into the two second rotating shaft grooves 20. Its structure is simple, easy to install, and easy to integrally injection mold.

[0039] In some embodiments, the first rotating shaft groove 19 and the second rotating shaft groove 20 are both U-shaped grooves, facilitating the installation and removal of the rotating shaft. The coil bracket 8 is locked onto multiple perforated connecting posts 22 inside the housing 1 by multiple fasteners 21. The fasteners 21 can be threaded connectors such as screws or bolts. The front end surface of the coil bracket 8 is in contact with or close to the rear end surfaces of the two rotating shaft plates 18, thereby restricting the rotation of the first rotating shaft 5 and the second rotating shaft 13 within the first rotating shaft groove 19 and the second rotating shaft groove 20, preventing the rotating shaft from moving out of the rotating shaft groove without affecting the rotation of the rotating shaft. In some embodiments, a counterweight 23, which is approximately triangular in shape, is provided at the rear end of each eyeball 4, which facilitates the automatic reset of the two eyeballs 4 when the power supply to the coil is stopped.

[0040] In some embodiments, magnet mounting holes 24 are provided in both the first magnet base 6 and the second magnet base 14, and coil receiving chambers 25 are provided in both the first coil base 9 and the second coil base 16; the magnet mounting holes 24 and the coil receiving chambers 25 can facilitate fixing the magnets and coils and prevent displacement or loosening.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
