Abstract
An optical disk control mechanism comprising an electric motor, a transmission component, a limiting switch and a sliding plate. The transmission component rotates when driven by the electric motor. The transmission component includes a first timing element and a second timing element. The limiting switch has a first electrode head and a second electrode head. The first timing element makes contact with the first electrode head so that the first electrode head and the second electrode head can connect electrically when the transmission component rotates. The sliding plate has an edge. The second timing element makes contact with the edge of the sliding plate and pushes the sliding plate along as the transmission component rotates.
Claims14
An optical disk control mechanism, comprising:
- a base frame,
- an electric motor fastened to the base frame, wherein the electric motor has a rotary transmission axle;
- a worm screw fixed to the transmission axle of the electric motor so that the worm screw rotates when driven by the transmission axle;
- a circular rod fixed to the base frame;
- a transmission component having a worm gear, a first eccentric wheel and a second eccentric wheel such that the first eccentric wheel and the second eccentric wheel are positioned to each side of the worm gear, wherein the transmission component has a hole corresponding to a center of the worm gear for sliding an entire transmission component into the circular pin through the hole so that the transmission component rotates using a center of the circular pin as a pivot, the worm screw meshing with the worm gear so that the transmission component rotates when driven by the worm screw, and after projecting shape centers of the first eccentric wheel, the second eccentric wheel and the worm gear onto a plane, a straight line from the shape center of the first eccentric wheel to the shape center of the worm gear and a straight line from the shape center of the second eccentric wheel to the shape center of the worm gear form a phase angle;
- a limiting switch fixed on the base frame, wherein the limiting switch has a first electrode head and a second electrode head, and the first eccentric wheel makes contact with the first electrode head so that the first electrode head makes contact with the second electrode head when the transmission component rotates;
- a sliding plate sliding on the base frame, wherein the sliding plate has an edge such that the second eccentric wheel makes contact with the edge and pushes the sliding plate along when the transmission component rotates;
- and
- a spring having one end fastened to the base frame while another end is fastened to the sliding plate.
