The present invention provides a shield apparatus of a head lamp for a vehicle. The shield apparatus of the head lamp for a vehicle includes: a case; a cover coupled to the case; a shield supported inside the case and configured to adjust a predetermined light beam pattern generated by a head lamp; a motor configured to drive the shield; a block disposed inside the case and the cover, and configured to rotatably support the shield and limit an angle of rotation of the shield.

An actuator is provided, which includes a stator, a rotor passing through the stator and rotated in an interaction with the stator upon supply of external power, a driven body operating in accordance with a rotation of an axis of the rotor, a case surrounding the stator such that the axis of the rotor is protruded, and one or more rotation angle regulators installed on an outer side of the case and regulating a rotation angle of the rotor. Further, an electronic device having the actuator mentioned above is also provided.

An apparatus for driving a headlamp shield is provided, which simplifies the operation structure of a bi-functional headlamp shield to reduce costs and improve quality. The apparatus includes a shield that rotates integrally with a rotary shaft thereof, and a coil section formed to cylindrically surround the rotary shaft, and that is configured to generate an electromagnetic force for moving the rotary shaft in a linear trajectory when a current is applied to the coil section. Further, a motion direction switching component adjusts the linear axial movement of the rotary shaft to axial rotation thereof.

An automotive headlamp module that reduces manufacturing cost and increases availability for low-cost vehicles is provided. The automotive headlamp provides a rotational force to a shield via a DC motor and improves safety during operation by implementing a beam pattern in a low-beam mode when performing a fail-safe function due to breakdown in a high-beam mode or an ADB mode. In particular, the automotive headlamp includes a drum type shield rotatably disposed with respect to a shield housing and has a high-beam protrusion, a low-beam protrusion, and an adaptive driving-beam (ADB) protrusion on an exterior side and a shield disc coupled to the shield that rotates. A housing disc guide is movable in a longitudinal direction of the shield by the shield housing and has an end in contact with the shield disc and a return spring and presses a housing disc to the shield disc with accumulated elastic force.
