Description of the Related Art Generally, a vehicle is provided with an illuminating function and an equalizing device for informing other users of a vehicle or other road users of the driving condition of the vehicle so that the user can see objects in the driving direction at night when driving. A head lamp, also referred to as a headlamp, is an illuminating lamp that illuminates the course ahead of the vehicle and requires brightness to identify obstacles on the road at a distance of 100 meters ahead at night. The standard of the headlamp is set differently from country to country, and in particular, the direction of irradiation of the headlamp beam is set differently depending on whether the vehicle is driven right (left driving) or left (right driving).

Conventional vehicle headlamps provide drivers with a fixed lighting pattern, regardless of varying road conditions. Therefore, the vehicle is relatively bright compared to other roads, such as high-speed driving, which requires longer viewing distance than other roads, and the glare is reduced due to the reflection of rain, snow, or wet roads, which are less dependent on the brightness of the headlamp. When driving in bad weather conditions that increase and the visibility decreases, a proper view for the driver to drive safely is not obtained.

5A and 5B are perspective views illustrating a first shield and a second shield arrangement in the shield driving apparatus according to the first embodiment of the present invention. 5A and 5B are for explaining the formation of the beam pattern according to the arrangement of the shield, and the present invention is not limited to the arrangement and shape of the shield.

5A and 5B, the second shield 210 and the first shield 220 may be disposed in parallel with respect to the rotation axes 212 and 222, respectively.

First, the second shield 210 may include one or more shield protrusions 232, 234, and 236 on the cylindrical outer circumferential surface 215. The pattern of the shield protrusion may vary depending on the beam pattern to be generated. The shield protrusion may be separated and positioned at an angle on the outer circumferential surface 215 of the cylinder. As shown in FIG. 5A, a part of the shield protrusion may be separated by forming a shield protrusion.

The second shield 210 may be operated by shield protrusions 232, 234, and 236 positioned at the top of the vertical line about the first rotation shaft 212.

For example, as shown in FIG. 5A, the first shield 220 rotates the second shield 210 while the first shield 220 is stopped, thereby placing the first shield protrusion 232 on a vertical line of the first rotation shaft 212. Can form a beam pattern.

Alternatively, the second shield 210 is rotated about the first rotation shaft 212 to 'activate' the second shield protrusion 234 or the third shield protrusion 236 so that a beam pattern of class V or E is generated. can do.

In addition, a beam pattern of class H can be generated by placing the cylindrical outer circumferential surface 215 of the shield on top of which no shield projections are 'activated'. Here, the cylindrical outer circumferential surface of the shield is used without a separate shield protrusion for class H. However, like class C, V, and E, the shield protrusion for class H can be placed on the cylindrical outer circumferential surface of the shield to generate a beam pattern of class H. Of course it can.

Here, 'activation' means that the shield protrusions 232, 234, and 236 attached to the outer circumferential surface 215 of the cylinder are positioned at the top of the vertical line to partially block light emitted to the front.

As such, when the second shield 210 is rotated based on the first rotation shaft 212, the beam patterns generated while the shield protrusions 232, 234, and 236 attached to the second shield 210 are activated may vary. .

Next, the first shield 220 biases and attaches the plate-shaped shield plate 224 to one side of the second rotation shaft 222. The second shield 220 is usually fixed in a state where the shield plate 224 is not vertically lowered. For example, if the shield plate 224 of the first shield 220 is fixed to face horizontally, as shown in FIG. 5A, the light provided by the lamp is reflected by the reflecting plate and directed forward. At this time, the shield plate 224 which is horizontal does not interfere with the light directed forward, so that the light directed forward is irradiated to the road surface. The stopping of the shield plate 224 at a level above or above the height of the shield plate 224 may prevent the first shield 220 from operating or 'deactivating' the shield plate 224.

Referring to FIG. 5B, the shield plate 224 may be activated by rotating the first shield 220 along with the second shield 210 onto the second rotation shaft 222.

For example, when the road surface, such as rain, gets wet, and the glare may be severely generated by the head lamp, the first shield 220 is rotated to reduce the amount of light in the near area, thereby rotating the shield plate 224. Can be lowered vertically. In this case, the light reflected by the reflector and directed toward the front may be partially blocked by the shield plate 224 of the first shield 220 to generate shadows in the near light region among the light regions facing forward.

That is, various beam patterns as described above may be formed by activating or deactivating the first shield and the second shield. However, as described above, FIGS. 5A and 5B illustrate beam patterns according to the arrangement of the shields. It is only for explaining the formation of the present invention, and the present invention is not limited to the arrangement and shape of the shield.

6 is an exploded perspective view of the shield driving apparatus according to the first embodiment of the present invention.

The upper case 415 and the lower case 417 serve as a housing for receiving the components of the shield drive device. Accordingly, the upper case 415 and the lower case 417 may be collectively referred to as a shield housing (not shown). The upper case 415 and the lower case 417 may be assembled by a predetermined fastening means, for example, bolts 406 and 407, and the bolt may simultaneously fasten the shield drive device with the holder. .

The step motor 480 provides a driving force for driving the first gear 420 and the second gear 425 through the step gear 485. The step motor 480 may receive a predetermined control signal from a controller (not shown) to rotate the step gear 485 in a predetermined direction to rotate the first gear 420 and / or the second gear 425. .

The first gear 420, the first sub gear 430, and the first spring 460 may constitute a first gear part (not shown), and the second gear 425 and the second sub gear 435. And the second spring 465 may constitute a second gear part (not shown). Here, the first gear 420 and the second gear 425 is located between the step gear 485 to rotate in engagement with the rotation of the step gear 485. For example, when the step gear 485 rotates in the clockwise direction, the first gear 420 and the second gear 425 rotate in the counterclockwise direction.

The first gear 420 includes a first protrusion 440 meshed with the first sub gear 430 to rotate, and the second gear 425 meshes with the first sub gear 435 to rotate. 445).

The first sub gear 430 and the second sub gear 435 may be coupled to and coupled to the first gear 420 and the second gear 425, respectively. The first sub gear 430 and the second sub gear 435 share the same rotation axis as the first gear 420 and the second gear 425, respectively. The first sub gear 430 and the second sub gear 435 may be integrally formed or fixed to the second shield (not shown) and the first shield (not shown), respectively. Therefore, the second shield rotates according to the rotation of the first sub gear 430, and the first shield rotates according to the rotation of the second sub gear 435.

As shown in FIG. 7B to be described later, the first sub gear 430 is formed of a predetermined 'no meshing part' even when the first protrusion 440 is rotated by a predetermined angle on the outer surface of the first sub gear 430. It may include one loop section 450 '. In other words, the first sub gear 430 may be formed in a shape obtained by cutting a fan-shaped shape by a predetermined angle from the disc.

As shown in FIG. 7B to be described later, the second sub gear 435 may be formed of a predetermined 'no engaging portion even when the second protrusion 445 rotates by a predetermined angle on the outer surface of the second sub gear 435. It may include two bullshit section 455 '. In other words, the second sub gear 435 may also be formed in a shape obtained by cutting a fan-shaped shape by a predetermined angle from the disc.

The first spring 460 and the second spring 465 serve to return the second shield and the first shield to the reference position, respectively. For example, when the power is applied to the stepper motor 480 in the off state, or when the power is applied to the adaptive headlamp device, or when it is determined as a fail, the elastic force is provided to provide the second force. The shield and the first shield may be returned to the reference position to enter the reference mode. Here, the 'reference mode' is a beam pattern mode which is automatically formed when the power is applied to the adaptive headlamp device or when the power is turned off, and the rotational position of the shield returns to a predetermined reference position or the reference position. Mode moved to position. In the present invention, a mode for generating a class C beam pattern may be referred to as a 'reference mode'. However, the present invention is not limited to the reference mode.
