  • Publication number: 20250074290
    Abstract: A vehicular headlamp adjustment device is provided which comprises a housing, and a motor assembly, a dual gear, a gear disk and an inner sleeve tube; a ball head ejector rod is helically assembled in the inner sleeve tube, and the motor assembly runs through a dual gear to drive the gear disk to rotate; the housing further comprises an outer sleeve tube. One end of the outer sleeve tube is rotatably connected to the housing, and the other end clamped and matched with the ball head ejector rod. When manually rotating the outer sleeve tube, the ball head ejector rod rotates with it; due to spiral fit between the ball head ejector rod and the inner sleeve tube, and the relative sliding between the outer sleeve tube and the ball head ejector rod, the ball head ejector rod expands and contracts axially under the action of the spiral structure.

  • 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.
