  • Publication number: 20240339908
    Abstract: A stepping dimming motor structure is provided, including a shell, and further including: a winding frame, which is provided with a coil, wherein a wiring block is arranged on a side circumferential wall of the winding frame; two wiring slots are arranged on the wiring block; each wiring slot corresponds to a wiring tab; a magnetically-conductive ring frame. The above scheme generates a magnetic field by powering up the coil to excite the magnetically-conductive ring frame, thus driving the rotor assembly to rotate; the rotor assembly then drives the push rod to move axially, adjusting headlights; and meanwhile, a fastening effect on lead wire ends of the coil and electrical connection between the lead wire ends of the coil and the wiring tabs are achieved through plugging fit between the wiring tabs and the wiring slots, thereby ensuring the structural reliability and improving the assembling efficiency.
