VEHICULAR HEADLAMP ADJUSTMENT DEVICE

A vehicular headlamp adjustment device is provided which comprises a housing (5), a motor assembly (2), a dual gear (4), a gear disk (6), an inner sleeve tube (7) and a ball head ejector rod (9) that is helically assembled in the inner sleeve tube (7), wherein the motor assembly (2) drives through the dual gear (4) the gear disk (6) to rotate, wherein the housing (5) further comprises an outer sleeve tube (8), one end of the outer sleeve tube (8) being rotatably connected to the housing (5) and the other end clamped and matched with the ball head ejector rod (9). When manually rotating the outer sleeve tube (8), the ball head ejector rod (9) rotates with it, wherein due to cooperating threads on the ball head ejector rod (9) and the inner sleeve tube (7) and the relative axial sliding between the outer sleeve tube (8) and the ball head ejector rod (9), the ball head ejector rod (9) expands and contracts axially under the action of the thread structure.
