Abstract

A headlamp for a vehicle is provided. The headlamp includes: a reflector which reflects light emitted from a light source; a lens which the light emitted from the light source penetrates; a lens holder which supports the lens; and a shield assembly which is provided between the reflector and the lens holder.

First claim

What is claimed is:

1. A headlamp for a vehicle, comprising:
a first frame comprising two opposing swivel connection portions through which a swivel axis passes;
a second frame fixed to a vehicle body, the first frame being connected with the second frame via the two opposing swivel connection portions such that the first frame is capable of swiveling about the swivel axis relative to the second frame;
comprising a reflecting surface configured to reflect light beams thereon, a lens placed in front of the reflector for receiving light beams reflected on the reflecting surface, the lens configured to redirect incident light beams as they pass therethrough;
a lens holder holding the lens; and
a shield assembly comprising a shield shaft, at least one shield attached to the shield shaft, and a motor operably connected to the shield shaft for rotating the shield shaft such that the at least one shield selectively blocks at least part of light beams traveling from the reflector toward the lens as the shield shaft rotates;
wherein the shield assembly is located within a horizontal extension of the reflector in a horizontal direction perpendicular to the swivel axis such that the motor of the shield assembly is located within the horizontal extension of the reflector when viewing the motor from the lens in a direction perpendicular to the swivel axis and the horizontal direction, wherein the motor and the shield shaft are arranged such that the motor's shaft extends generally parallel to the shield shaft and below the shield shaft;
wherein the shield assembly is provided between the reflector and the lens holder and is fixed to the first frame along with the reflector and the lens holder such that the shield assembly including the shield and the motor swivels together with the reflector and the lens holder about the swivel axis relative to the second frame.

2. The headlamp of claim 1 , wherein the shield assembly further comprises a shield frame to which the motor is fixed, wherein the shield frame is integrated with the first frame.

3. The headlamp of claim 1 , wherein the shield shaft is engaged with the motor by mechanical gears.

4. The headlamp of claim 3 , wherein the mechanical gears comprise:
a first gear engaged with the shield shaft; and
a second gear engaged with the first gear.

5. The headlamp of claim 1 , wherein the first frame includes a first connecting portion, the shield assembly includes a second connecting portion, the lens holder includes a third connecting portion, wherein the reflector, the shield assembly and the lens holder are fixed to the first frame such that the first connecting portion of the first frame is sequentially connected to the second connecting portion of the shield assembly and the third connecting portion of the lens holder.

6. The headlamp of claim 5 , wherein the first connecting portion includes a coupling projection, the second connecting portion includes a through hole, the third connecting portion includes an insertion groove, and the coupling projection penetrates the through hole and is inserted into the insertion groove.

7. The headlamp of claim 1 , further comprising:
a frame swivel assembly operably connected to the first frame and configured to move the first frame for swiveling about the swivel axis,
wherein the frame swivel assembly includes:
a swivel actuator; and
a swivel shaft connected to the swivel actuator.

8. The headlamp of claim 7 , wherein the first frame includes a swivel shaft connecting portion connected to the swivel shaft, and the second frame includes a through hole through which the swivel shaft penetrates.

9. The headlamp of claim 8 , further comprising:
a lamp housing connected to the vehicle body,
wherein the second frame is fixed to the vehicle body via the lamp housing.

10. The headlamp of claim 1 , wherein the reflector has a width in a direction when viewed along the swivel axis, wherein the shield assembly has a width in the direction that is equal to or narrower than the width, of the reflector.
