The present invention relates to a shield driving device of a head lamp, and more particularly, to a shield driving device of a head lamp providing a beam pattern suitable for a driving environment of a vehicle.

In general, the vehicle is provided with a head lamp (head lamp) so that you can see the object in the driving direction when driving at night.

The headlamp is a light that functions to illuminate the path ahead of the vehicle and needs brightness to identify obstacles on the road at night. Such vehicle headlamps provide the driver with a fixed beam pattern regardless of varying road conditions.

The above technical configuration is a background art for helping understanding of the present invention, and does not mean a conventional technology well known in the technical field to which the present invention belongs.

This fixed beam pattern does not provide the driver with adequate visibility for safe driving in bad weather conditions where glare is increased and visibility is reduced due to reflection of wet roads.

Accordingly, the present invention provides a shield driving device of a head lamp that enables a driver to drive safely by generating a beam pattern that can reduce glare due to reflection of wet roads in bad weather and secure a long-distance view. There is a purpose.

The configuration of the present invention, which is invented to achieve the above-described object, is as follows.

The shield driving device of the head lamp according to the present invention includes a rotation shield for changing the pattern of the beam irradiated according to the rotation angle, and a rain mode shield for partially blocking the beam irradiated at a short distance by the rotation of the rotation shield in the rainy mode. And a shield driver for rotating the rotary shield at a predetermined angle in response to a driving signal.

In the present invention, it is characterized in that it further comprises a guide spring for moving the rain mode shield by converting the rotational motion of the rotary shield to linear motion.

In the present invention, the rotating shield is characterized in that for forming at least one shield projection on the cylindrical circumferential surface.

In the present invention, when the rain is detected, the controller may further include a controller for entering the rainy mode and outputting the driving signal.

In the present invention, the controller is characterized in that entering the rain mode when the operation of the wiper for a predetermined time.

According to the present invention configured as described above, the driver can drive safely by generating a beam pattern that can reduce glare due to the reflection of the wet road in bad weather and ensure a long-distance view.

Hereinafter, the present invention will be described in more detail with reference to Examples. These embodiments are only for illustrating the present invention, and the scope of rights of the present invention is not limited by these embodiments.

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, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout the specification.

1 is a block diagram illustrating a configuration of a shield driving apparatus of a head lamp according to an embodiment of the present invention.

Referring to FIG. 1, the present invention provides a control unit 1 for outputting a driving signal DS that is activated in a rainy weather mode, and a beam irradiated from a headlamp to a long distance in response to the driving signal DS. The beam irradiated with includes a shield driving device 2 which drives to block a part.

The controller 1 detects rain through a rain sensor (not shown) and enters rainy mode or enters rainy mode when the wiper continues for a certain time, and activates and outputs a driving signal DS when entering rainy mode. .

The shield drive device 2 includes a shield driver 21 for driving in response to a drive signal DS output from the controller 1, a rotation shield 22 that rotates at an angle by driving the shield driver 21, A guide spring portion 23 for converting the rotational movement of the rotary shield 22 into a linear movement, and the rain mode mode shield 24 for moving in front of the headlamp by the linear movement of the guide spring 23.

The shield driving device 2 rotates the rotary shield 22 at a predetermined angle in rainy mode to change the pattern of the beam so that the beam is irradiated to a long distance, and rotates the rainy mode shield 24 by the rotation of the rotary shield 22. It moves in front of the lamp to block some of the near-field radiation.

The configuration and operation of the shield driving device 2 will be described in more detail as follows.

2 and 3 are views for explaining the configuration of the shield driving device of the head lamp according to an embodiment of the present invention.

2 and 3, the rotary shield 22 forms one or more shield protrusions 221 (see FIG. 2) on a cylindrical circumferential surface. The rotation shield 22 is rotated by a predetermined angle by the drive of the shield driver 21, and changes the pattern of the beam irradiated from the lamp 33 by the shield projection 221 according to the rotation angle.

The guide spring portion 23 converts the rotational movement of the rotary shield 22 into a linear movement, and the rain mode shield 24 blocks the beam irradiated at a near distance of the vehicle by the linear movement of the guide spring portion 23. Go to.

That is, the shield driving device 2 rotates the rotation shield 22 at an angle in response to the driving signal DS activated in the rainy weather mode so that the beam irradiated from the lamp 33 is reflected by the reflector 32 and the lens 31. To be surveyed over long distances.

In addition, by rotating the rotary shield 22, the rain mode shield 24 is moved forward to partially block the beam irradiated from the lamp 33 from being irradiated to the near field of the vehicle via the reflector 32 and the lens 31. .

4 and 5 are views for explaining the operation of the shield driving device of the head lamp according to an embodiment of the present invention.

4 and 5, when rain is detected (S1), the controller 1 enters the rainy mode (S2), and activates and outputs the driving signal DS (S3).

Then, the shield driver 21 is driven by the driving signal DS, and the rotation shield 22 is rotated by a predetermined angle by the shield driver 21.

The beam irradiated from the lamp 33 by the pattern change of the beam by the rotation of the rotary shield 22 is irradiated to a long distance through the reflector 32 and the lens 31 (S4).

Subsequently, the guide spring portion 23 converts the rotational movement of the rotary shield 22 into a linear movement, and the rainy mode shield 24 moves forward of the lamp by the linear movement of the guide spring portion 23.

As a result of the movement of the rainy mode shield 24, a part of the beam in the near area irradiated from the lamp 33 is blocked (S5).

FIG. 6 is a view for explaining an area of a beam by a shield driving apparatus of a head lamp according to an embodiment of the present invention.

Referring to FIG. 6, the shield driving apparatus of the head lamp according to the present invention improves the far region rather than the low beam in rainy mode, and partially blocks and regulates the beam of the near region.

As described above, the present invention can reduce the glare caused by the reflection of the wet road by restricting the near area in rainy mode, and improve the far area to generate a beam pattern that can secure a long-distance view so that the driver can drive safely. Make sure

As described above, the present invention has been described with reference to the embodiments shown in the drawings, but this is merely exemplary, and various modifications and equivalent other embodiments of the present invention may be made by those skilled in the art. I understand that it is possible. Therefore, the true technical protection scope of the present invention will be defined by the claims below.
