Abstract: An apparatus is adapted for controlling a lamp unit mounted on an automobile body, and includes a housing for housing input and output rods, and a transmission gear. The transmission gear meshes with a worm segment of the input rod such that the transmission gear is driven by the worm segment to rotate in response to rotation of the input rod. The output rod has a coupling end portion coupled to the lamp unit, and a rack segment meshing with the transmission gear such that the output rod is movable relative to the housing in response to rotation of the transmission gear, thereby driving movement of the lamp unit relative to the automobile body.

Abstract: An apparatus is adapted for controlling a lamp unit mounted on an automobile body, and includes a housing for housing input and output rods, a deceleration unit and a transmission piece. The deceleration unit includes a planet gear connected to an eccentric engaging end portion of the input rod, meshing with a ring gear fixed in the housing, and connected to the transmission piece and an angle indicating unit sleeved on the input rod. The output rod has a coupling end portion coupled to the lamp unit, and a rack meshing with a center gear portion of the transmission piece. When the input rod rotates, the transmission piece and the angle indicating unit are driven to rotate in response to movement of the planet gear such that the output rod is movable in response to rotation of the transmission piece, thereby driving movement of the lamp unit relative to the automobile body.

Abstract: An apparatus is adapted for controlling a lamp unit mounted on an automobile body, and includes a housing for housing input and output rods, a deceleration unit and a transmission piece. The deceleration unit includes a planet gear connected to an eccentric engaging end portion of the input rod, meshing with a ring gear fixed in the housing, and connected to the transmission piece. The output rod has a coupling end portion extending out of the housing and coupled to the lamp unit, and a rack meshing with a center gear portion of the transmission piece. When an operating end portion of the input rod rotates, the transmission piece is driven to rotate in response to movement of the planet gear with the engaging end portion of the input rod such that the output rod is movable in response to rotation of the transmission piece, thereby driving movement of the lamp unit relative to the automobile body.
