In addition, the headlamp for a vehicle according to the present invention is provided with a connection member formed with a curved sliding groove, so that the mounting position of the driving unit can be determined by varying the shape of the sliding groove, thereby increasing the design freedom, and the sliding groove portion By varying the shape, it is possible to adjust the rotation angle and the rotation speed of the rotating reflector, which has the advantage of more effectively securing the driver's field of view at night.

Hereinafter, an embodiment of a headlamp for a vehicle according to the present invention will be described with reference to the accompanying drawings.

In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description.

In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to a user's or operator's intention or custom.

Therefore, definitions of these terms should be made based on the contents throughout this specification.

1 is a perspective view showing a headlamp for a vehicle according to an embodiment of the present invention, Figure 2 is an exploded perspective view showing a headlamp for a vehicle according to an embodiment of the present invention, Figure 3 is an embodiment of the present invention A perspective view of the connection member of the headlamp for a vehicle is shown.

1 to 3, the headlamp for a vehicle according to the exemplary embodiment of the present invention is rotatably installed in the frame 10 and reflects light reflected from a light source (not shown) to the front 30. And a connecting member 70 provided with a driving unit 50 for rotating the reflector 30 and a sliding groove portion 78 provided between the reflector 30 and the driving unit 50 to rotate the reflector 30. It includes.

Since the reflector 30 has a first coupling part 32 formed at an upper end thereof, and a second coupling part 34 formed at a lower end thereof, the reflector 30 is rotatably installed in the left and right directions in the frame 10, and the second coupling part 34 is disposed. The drive shaft 36 is formed in the lower portion away from the predetermined distance and is inserted into the sliding groove (78).

Accordingly, when the driving shaft 36 is moved by the driving unit 50, the reflector 30 is rotated in the left and right directions with the first coupling unit 32 and the second coupling unit 34 as the rotation center, and thus, according to the traveling direction of the vehicle. This results in an adaptive front lighting system (AFLS) in which the direction of light emitted from the headlamps is varied.

Since the spherical portion 38 is formed at the end of the drive shaft 36, the area in contact with the inner wall of the sliding groove 78 is reduced, so that the drive shaft 36 inserted into the sliding groove 78 can be easily slid.

Since the driving unit 50 includes a motor having an arm 52 which is linearly moved and is sunk, when the arm 52 is sunk by the driving of the motor, the connecting member 70 moves linearly in the direction in which the arm 52 is sunk. The drive shaft 36 inserted into the sliding groove 78 slides along the sliding groove 78 so that the reflector 30 is rotated.

In addition, since the curved portion 54 is formed at the end of the arm 52, it can be coupled while sliding easily into the seating portion 72 of the connecting member 70 to be described later.

The connection member 70 includes a seating portion 72 to which the curved portion 54 is coupled, and a curved sliding groove 78 to which the spherical portion 38 is movably inserted.

Accordingly, the arm 52 of the driving unit 50 is coupled to the seating unit 72, and the driving shaft 36 of the reflector 30 is inserted into the sliding groove 78 so that the driving unit 50 and the reflector 30 Since the connection can be made, the connection is made by converting the linear motion into the rotational motion without a separate connecting member rotatably connected like a bearing.

The seating portion 72 includes an elastic portion 74 in which the seating portion 72 is partially cut, and an elastic protrusion 76 for pressing the curved portion 54.

Accordingly, when the arm 52 of the driving unit 50 is inserted into the seating portion 72, the curved portion 54 of the arm 52 pushes the seating portion 72 outward, so that the elastic portion 74 is outward. As the elastic protrusion 76 is deformed in the outward direction, the arm 52 is inserted into the seating portion 72.

When the insertion of the arm 52 is completed, the elastic portion 74 and the elastic protrusion 76 are restored to their original state, and are in close contact with the curved portion 54, whereby the arm 52 and the connecting member 70 are coupled.

Since the sliding groove 78 is formed in a 'S' shape by successive curves arranged in different directions, respectively, when the driving unit 50 pulls the connecting member 70, the driving shaft 36 moves toward one side of the connecting member 70. The reflector 30 rotates while sliding, and when the driving unit 50 pushes the connecting member 70, the drive shaft 36 slides in the other direction of the connecting member 70 to rotate the reflector 30.

Since the position in which the driving unit 50 is installed may vary depending on the shape of the sliding groove 78, the design freedom degree is improved, and the shape of the sliding groove 78 and the position of the driving unit 50 are varied to rotate. Since the rotation angle and rotation speed of the reflector 30 can be adjusted, the designer can easily design the desired adaptive front lighting system (AFLS).

In addition, since the shape of the sliding groove 78 can be easily changed and implemented by those skilled in the art having recognized the technical configuration of the present invention, specific drawings or descriptions of other embodiments of the sliding groove will be omitted.

Looking at the operation of the vehicle headlamp according to an embodiment of the present invention configured as described above are as follows.

When the driver manipulates the steering wheel to the left in the traveling direction at night, the driving unit 50 is operated to pull the connecting member 70 so that the arm 52 is inserted into the motor side, so that the spherical portion of the driving shaft 36 38 is slid along the inner wall of the sliding groove 78 and rotated in a direction far from the driving unit 50.

Therefore, the reflector 30 is rotated in a left direction around the first connection part 32 and the second connection part 34, thereby securing a driver's view of the vehicle traveling to the left.

On the contrary, when the traveling direction of the vehicle is changed to the right side, the driving unit 50 is operated to push the connecting member 70 so that the arm 52 protrudes out of the motor, so that the spherical portion 38 of the driving shaft 36 is the sliding groove part ( 78 is rotated in the direction close to the drive unit 50 while sliding along the inner wall.

Therefore, the reflector 30 is rotated in the right direction around the first connection portion 32 and the second connection portion 34, thereby securing a driver's view of the vehicle traveling to the right.

As a result, it is possible to provide a vehicle headlamp that can reduce the number of parts and improve design freedom.
