Abstract:
1. A rotating window comprising: a base member, which is provided with a circular groove, with a support bracket being connected between inner walls of the circular groove, a center of the support bracket being provided with a sleeve having a shaft hole, and an exterior side of the support bracket being a hollow area; and coil seats, which are wound by a plurality of metallic coils and are fixedly connected in an interior of a magneto-conductive element, with the magneto-conductive element being fixedly connected into the circular groove; the rotating window being loosely connected into the circular groove to form a motor stator and being constituted by (a) a turntable, a center of which is provided with a through-hole, and an inner side of which is provided with a flange, with a transparent window being fixed into and sealing the through-hole; (b) a back iron, which is made by a magneto-conductive material and is sheathed and fixed at a side of a permanent magnet ring, with the magnet ring and the back iron being sheathed together and fixed on a surface of the flange, and then sheathed at an inner side of the base member, thus further forming an air gap between the magnet ring and an inner wall of the magneto-conductive element; and (c) a spindle, which is loosely connected into the shaft hole, with a shaft end being fixed in a center of the rotating window; the base member being fixed on an inner surface of a static transparent board; the magneto-conductive element forming a motor stator to result in an electro-magnetic field to drive the magnet ring to rotate, with the rotating window rotating along with the magnet ring simultaneously to sling off any liquid or debris which sprays on a surface of the transparent window.
