Abstract
A light distribution switching device of a head lamp may include: a housing installed at the front of a light source of the head lamp; a shield part rotatably installed in the housing, and adjusting movement of light irradiated from the light source depending on a rotational position; a rotating gear mounted on the shield part and rotated with the shield part; a driving part rotating a driving gear engaged with the rotating gear; and an elastic return part installed on the shield part, and moving the shield part to the original position when the driving part is stopped.
Claims6
A light distribution device of a head lamp, comprising:
- a housing installed in front of a light source of the head lamp;
- a shield part rotatably installed in the housing, and configured to adjust movement of light irradiated from the light source depending on a rotational position;
- a rotating gear mounted on the shield part and configured to rotate together with the shield part;
- a driving part configured to rotate a driving gear engaged with the rotating gear;
- an elastic return part installed on the shield part, and configured to move the shield part to an original position when the driving part is stopped;
- and
- a holder part forced into a connection hole through the housing, the connection hole being formed at a side surface of the shield part,
- wherein the holder part comprises:
- a head member locked to the outside of the housing;
- an extended body extended from the head member, and forced into the connection hole;
- and
- a deformable protrusion protruding to the outside of the extending member, and configured to deform by the operation of forcing the extended body into the connection hole.
A light distribution device of a head lamp, comprising:

- a driving part configured to rotate a driving gear engaged with the rotating gear;
- an elastic return part installed on the shield part, and configured to move the shield part to an original position when the driving part is stopped;
- and
- a holder part forced into a connection hole through the housing, the connection hole being formed at a side surface of the shield part,
- wherein the housing comprises:
- a first body part having a first mounting groove to which both sides of the driving part are inserted and coupled;
- and
- a first support part extended from the first body part and rotatably supporting the shield part,
- wherein the holder part is forced into the connection hole through the first support part.
