BACKGROUND OF THE INVENTION
The present invention relates to a vehicular lamp for lighting purposes such as a headlamp and a fog lamp, and more specifically, a configuration in which an irradiation axis of a light distribution moves in a turning direction and irradiates a subsequent traveling direction as the vehicle turns. This relates to the variable light distribution headlamp.
[0002]
[Prior art]
3 and 4 show an example of the configuration of a conventional variable light distribution headlamp 90 of this type. The variable light distribution headlamp 90 includes a light source 92 attached to a reflecting mirror 91. At the position of the light source 92, it is pivotally supported by a rotating shaft 93 in the vertical direction when attached to the vehicle body. The rotating shaft 93 is interlocked with a steering device (not shown) such as a steering shaft, for example, and moves the irradiation axis X in the turning direction of the vehicle as the driver operates the steering wheel. .
[0003]
In addition, a housing or an extension 94 is provided on the front side portion of the reflecting mirror 91 in order to improve the appearance when the reflecting mirror 91 is attached to a vehicle so as to obtain a sense of unity between the reflecting mirror 91 and the vehicle body. . In addition, an outer lens 95 is provided in front of the variable light distribution headlamp 90 to seal the variable light distribution headlamp 90.
[0004]
In this way, when the vehicle approaches a curved road during driving with the variable light distribution headlamp 90 lit at night or the like, as shown in FIG. As shown in FIG. 4, the light distribution irradiation axis X rotates in the turning direction and the variable light distribution headlamp 90 changes the irradiation direction as shown in FIG. Since it is directed in the turning direction, it is easy to check the road surface condition and the like to travel afterwards, that is, it is effective for improving safety.
[0005]
[Problems to be solved by the invention]
In the variable light distribution headlamp 90 having the above-described conventional configuration, when the vehicle turns, the reflecting mirror 91 and the light source 92 fixed thereto are rotated in the turning direction. At this time, when viewed from the front of the vehicle As a result, the back surface of the reflecting mirror 91 is viewed, and the appearance is poor.
[0006]
Further, as the reflecting mirror 91 rotates, a gap is formed between the extension 94 and the variable light distribution headlamp 90 and the inside of the adjacent lamp are viewed through the gap. It became a thing, and it became a thing of worse appearance.
[0007]
[Means for Solving the Problems]
According to the present invention, as a specific means for solving the above-described conventional problems, a reflecting mirror and a light source provided in a housing are rotated according to turning of the vehicle so that the main axis of light distribution is centered on the vehicle in the vehicle turning direction. In the variable light distribution headlamp to be moved from above, a standing wall extending rearward or laterally from the reflection mirror is formed near the horizontal end of the reflection mirror. By providing, it solves the problem.

DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described in detail based on embodiments shown in the drawings. FIG. 1 shows a first embodiment of the present invention, and what is denoted by reference numeral 10 in the figure is a variable light distribution headlamp according to the present invention. The variable light distribution headlamp 10 has a light source 2 such as an incandescent lamp attached to a predetermined position of a reflecting mirror 1, and the reflecting mirror 1 has a parabolic reflecting surface, a free curved surface, or the like.
[0009]
Then, at the position of the light source 2, it is pivotally supported by the rotating shaft 3 in the vertical direction in a state of being attached to the vehicle body. The rotating shaft 3 is linked to a steering device (not shown) such as a steering shaft, and moves the irradiation axis X in the turning direction of the vehicle as the driver operates the steering wheel. .
[0010]
The side of the front surface of the reflecting mirror 1 is provided with a housing and an extension 4 in order to improve the appearance when attached to a vehicle so as to obtain a sense of unity between the reflecting mirror 1 and the vehicle body. I have to. Further, an outer lens 5 is provided in front of the variable light distribution headlamp 10 to seal the variable light distribution headlamp 10. The above configuration is the same as that of the conventional example.
[0011]
Here, in the first embodiment of the present invention, the standing wall 6 is provided at the horizontal end of the reflecting mirror 1. The standing wall 6 will be described in detail. Flat plates having substantially the same width as the vertical thickness of the reflecting mirror 1 so as to extend from the front end to the rear end of the reflecting mirror 1 at both ends in the horizontal direction of the reflecting mirror 1. Or it consists of a curved plate. The standing wall 6 may be formed integrally with the reflecting mirror 1, or a separate member may be attached later as in the first embodiment.
[0012]
For the standing wall 6, use of the same material as that of the reflecting mirror 1 eliminates the process, but it is naturally possible to use a completely different material. The outside of the standing wall 6 is subjected to the same reflection treatment as that of the inner surface of the reflecting mirror 1, and the rear end is curved outward as necessary.
[0013]
According to the above configuration, the steering device is operated when the vehicle reaches, for example, a curved road that requires a right turn, and the reflecting mirror 1 also rotates to the right by an angle corresponding to the operation amount of the steering device. Is directed in a predetermined direction. At this time, one end of the reflecting mirror 1 protrudes toward the extension 4 due to the rotation of the reflecting mirror 1, but in the first embodiment, the standing wall 6 is formed at this position. Unlike the conventional example, the back surface of the reflecting mirror 1 is not viewed.
[0014]
Further, since the outside of the standing wall 6 is subjected to a reflection process or the like and is similar to the reflecting surface of the reflecting mirror 1, the appearance is excellent. Although the example in which the reflection processing is performed on the outside of the standing wall 6 has been described, when a housing or a body is positioned instead of the extension 4, it is possible to make the same as those colors.
[0015]
Next, FIG. 2 is a second embodiment of the variable light distribution headlamp 10 according to the present invention, and also in this second embodiment, a reflecting mirror 1 that rotates according to the operation amount of the steering device is provided. This is the same as in the previous first embodiment, and the same is true in that a standing wall 6 is provided at the end of the reflecting mirror 1, but in the second embodiment, a rib is further provided. 7 is provided.
[0016]
The rib 7 is made of a curved plate having a width equal to or larger than the thickness of the reflecting mirror 1 in the vertical direction, and is disposed so as to mainly cover the horizontal side surface of the reflecting mirror 1. The attachment is performed on the extension 4 or a housing or body (not shown). Of course, the rib 7 may be integrally formed with the extension 4, a housing or a body (not shown).
[0017]
The rib 7 is knurled, and the steering device is operated, the variable light distribution headlamp 10 is driven, the reflecting mirror 1 rotates, and the light emitted from the light source 2 is A treatment for preventing glare light due to reflection on the rib 7 may be performed. The first purpose of the rib 7 is to prevent the reflecting mirror 1 from rotating due to the movement of the variable light distribution headlamp 10 and the inside of the variable light distribution headlamp 10 from being viewed. Therefore, the rib 7 is simply made the same color as the housing and the body, and even if the rib 7 is viewed, it is sufficient that it does not give a sense of incongruity.
[0018]
As described above, according to the second embodiment, since the rib 7 is formed even when the variable light distribution headlamp 10 is driven and the reflecting mirror 1 is rotated and a gap is generated, the variable distribution headlamp 10 is formed. The inside of the optical headlamp 10 and other lamps connected to the optical headlamp 10 is not viewed, and the appearance is excellent. Further, if an appropriate knurled cut is made on the rib 7, the occurrence of glare light by the variable light distribution headlamp 10 can be prevented.
[0019]
【The invention's effect】
Since the variable light distribution headlamp 10 is configured as described above according to the present invention, the back surface of the reflection mirror 1 can be viewed even when the reflection mirror 1 is rotated by driving the variable light distribution headlamp 10. However, the standing wall 6 is viewed, and the reflecting wall 1 is rotated by the variable light distribution headlamp 10 by making the standing wall 6 have the same reflection treatment and color as the extension 4, the housing and the body. Even if it does, it will have a sense of unity with the car body, and will be excellent in aesthetics.
[0020]
In addition, by providing the rib 7, the rib 7 can be viewed even when the reflecting mirror 1 is rotated by driving the variable light distribution headlamp 10 and a space is formed between the extension 4. Therefore, the inside of the variable light distribution headlamp 10 and other lamps adjacent to the variable light distribution headlamp 10 is not viewed, and the appearance of the variable light distribution headlamp 10 is not deteriorated by driving the variable light distribution headlamp 10. Furthermore, if a predetermined knurled cut or the like is applied to the rib 7, glare light will not be generated, and harmony with other lamps will be achieved, resulting in a sense of unity.
