Description

The present invention relates to a headlight structure capable of compactly setting the outer shape of a headlamp because it is not necessary to provide a dedicated lighting chamber for arranging a light source of a position lamp of an automobile or the like.

Conventionally, in a position lamp that does not have a dedicated lighting room in an automobile or the like and uses a reflector of a headlamp as a reflecting surface, it is necessary to arrange a bulb in the reflector in order to irradiate the reflector with light. There was a hole for the position lamp bulb to penetrate. When adjusting the optical axis of the headlamp, this reflector moves, so it was necessary to provide a gap around it so that the position lamp bulb would not interfere with it, which was unattractive.
Therefore, there is known a prior art (see Patent Document 1) in which a position lamp bulb (also referred to as a clearance bulb) is arranged outside the reflector of the headlamp bulb. In this prior art, the light of the clearance bulb is focused by a condenser lens, reflected by the reflecting surface formed on the extension reflector, and guided to the inside of the reflector through the gap. The light of the clearance bulb guided to the inside of the reflector is reflected toward the lens by the reflecting surface formed on the outer peripheral surface of the cap portion of the hood cap, and is emitted through the lens.

Japanese Unexamined Patent Publication No. 10-261303

As described above, in the prior art, the light of the clearance bulb is guided to the extension reflector through the passage on the back side of the reflector, and is reflected by the reflecting surface formed on the outer peripheral surface of the cap portion of the hood cap provided around the headlamp. Since it is necessary, the configuration becomes complicated, the cost increases, and the size of the device increases.

According to the present invention, even if the position lamp light source is incorporated in the headlight, the appearance is not deteriorated regardless of whether the headlight is lit or not, and the appearance of the position lamp light source is not conspicuous even when the headlight is not lit. It is intended to provide a headlight structure capable of.

In order to solve the above problems, the present invention is arranged so that the position lamp light source is viewed from above and behind the head lamp reflector of the head lamp section, and the position lamp light source is viewed from the front view and the design surface or head of the head lamp section. It is placed at a position that overlaps with the lamp reflector, and an inner lens that transmits the light from the position lamp light source is installed in a part of the head lamp reflector, and the inner reflector that reflects the light from the position lamp light source makes the reflecting surface inside the vehicle. The position lamp light source is arranged at the rear side of the head lamp reflector, and the reflected light of the inner reflector is directed toward the rear of the vehicle through the inner lens, and the position lamp light source is set at the angle of the optical axis transmitted in front of the head lamp reflector. It is in the arrangement .

Since it is not necessary to provide a lighting chamber dedicated to the position lamp, the outer shape of the headlamp can be designed compactly, and the entire device can be made compact.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings of the headlights on the left side of the vehicle.
In FIGS. 1 and 2, reference numeral 1 denotes a resin-molded headlamp housing that constitutes the light chamber of the headlight on the left side of the vehicle, and faces the inside of the headlamp housing 1 that constitutes the light chamber. A headlamp portion 2 on the left side and a turn lamp portion 3 on the right side are provided. An outer lens 4 for light distribution is provided on the front surface of the opening of the headlamp housing 1.

The headlamp portion 2 is a headlamp reflector 5 through a headlamp reflector 5 formed in a concave shape constituting the dome-shaped reflecting surface 5A and an opening hole 5a formed in the central portion of the headlamp reflector 5. It is composed of a main light source 6 in which the tip of the valve is arranged on the front axis. The turn lamp portion 3 is arranged on the outside of the vehicle body side by side with the headlamp portion 2 in the vehicle width direction, and a bulb (not shown) serving as a direction indicator is arranged. The turn lamp portion 3 is provided in a recess 7a extending to the outside of the vehicle body of the extension 7 provided so as to cover the peripheral edge portion of the headlamp reflector 5.

A gap 8 is provided between the headlamp reflector 5 of the headlamp section 2 adjacent to the turn lamp section 3 and the headlamp housing 1 in a top view, and the position lamp light source 9 is provided in the gap 8.

The position lamp light source 9 is arranged behind the headlamp reflector so that the optical axis is slightly to the left of the front of the vehicle body or the front of the vehicle body, and the inner reflector 10 is on the side surface on the front left side surface of the position lamp light source 9. It is arranged so as to face.
An inner lens in which the position lamp light source 9 is arranged at a position overlapping the design surface of the headlamp portion 2 or the headlamp reflector 5 in front view, and a part of the headlamp reflector 5 transmits light from the position lamp light source 9. 11 is installed.
The inner reflector 10 is arranged so as to form a substantially triangular shape with the position lamp light source 9 and the back surface of the headlamp reflector 5. An opening hole 5b is formed in the reflective surface 5A of the headlamp reflector 5, and the inner lens 11 is mounted in the opening hole 5b. The inner reflector 10 is formed by being curved in an arcuate concave portion, and the reflecting surface 10a so as to reflect the light of the position lamp light source 9 on the curved surface of the inner reflector 10 and irradiate it through the inner lens 11. Is formed.

According to the embodiment, when the position lamp light source 9 is turned on, the light emitted from the position lamp light source 9 is reflected by the reflecting surface 10a of the inner reflector 10 and passed through the inner lens 11 to the headlamp reflector 5. It is illuminated inside. In this way, the headlamp reflector 5 is reflected to the reflecting surface 5A and is irradiated to the outside through the outer lens 4.

FIG. 3 is another embodiment of the present invention without using the inner reflector 10. In this case, the same parts as those in FIG. 2 are designated by the same reference numerals, and the description of the same parts will be omitted.
_In this case, by arranging the optical axis of the position lamp light source 91 toward the front, the inside of the headlamp reflector 5 is irradiated through the inner lens 11. In this way, the light is reflected to the outside through the outer lens 4 while being reflected by the headlamp reflector 5.

In this case, the inner lens 11 is configured to illuminate the optical axis of the position lamp light source 92 in front of the vehicle. Through the inner lens 11, light is radiated to the front of the vehicle, a part of the light is radiated toward the reflector, and the reflective surface 5A of the headlamp reflector 5 is radiated through the inner lens 11. Further, by installing the position lamp light source 93 at an angle to the outside of the vehicle _, the light reflected by the inner reflector 10 can be applied to the reflecting surface 5A of the headlamp reflector 5 through the inner lens 11. ..

FIG. 5 is a modification in which the same parts as those in FIG. 3 are designated by the same reference numerals. _In this case, the position lamp light source 94 is arranged so that the optical axis faces the inside of the vehicle. In this way, the light from the position lamp light source 9 ₄ is irradiated to the inside of the headlamp reflector 5 through the inner lens 11, and is emitted to the outside through the outer lens 4 while being reflected by the reflecting surface 5A of the headlamp reflector 5.
Further, the position lamp light source ₉₅ is arranged so that the optical axis faces the inside (just beside) in the vehicle width direction of the vehicle. In this way, the light radiated to the inside of the headlamp reflector 5 through the inner lens 11 is reflected to the outside through the outer lens 4 while being reflected by the reflecting surface 5A of the headlamp reflector 5.

As described above, according to the present invention, the position lamp light sources 9, 91, 92, 9 ₃ , _{9 4 , 95} are arranged behind the headlamp reflector ₅ of the headlamp unit 2 in a top view. There is. The position lamp light sources 9, 9 ₁ , 92, _{9 3} , _{9 4 ,} and 95 are arranged in front view and at a position overlapping the design surface of the headlamp portion 2 or the headlamp reflector 5. Further, an inner lens ₁₁ that transmits light from the position lamp light sources _{9 ,} 91, 92, 93, ₉₄ , and 95 is installed in a part of the headlamp reflector ₅ . Therefore, even if the structure incorporates the position lamp light sources ₉ , 9 ₁ , 92, 9 ₃ , _{9 4 ,} 95 in the headlight, the appearance does not deteriorate regardless of whether the headlight is on or off, and the appearance is not deteriorated when the headlight is not on. However, it is possible to obtain a headlight structure that can maintain the appearance in which the presence of the position lamp light sources _{9 , 91} , 92, 93, ₉₄ , and ₉₅ is inconspicuous. In addition, since it is not necessary to provide a dedicated lighting chamber for the position lamp light sources 9, 91, 92, _{9 3} , _{9 4 , 95} , the outer shape of the headlamp can be designed compactly. By reducing the number of parts, the entire device can be made compact.

An inner reflector 10 that reflects light from the position lamp light sources _{9 ,} 92, and 93 is arranged behind the head lamp reflector 5, and the reflected light of the inner reflector 10 is passed through the inner lens 11 to the head. Since the reflecting surface 10a of the inner reflector 10 is arranged so as to transmit light in front of the lamp reflector 5, the degree of freedom in the installation positions of the position lamp light sources _{9 ,} 92, and 93 is improved, and the degree of design freedom is improved. Since the light distribution can be adjusted more, the headlamp reflector 5 can be widely used. Since the light is blocked by the inner reflector 10, it is possible to reduce light leakage from the position lamp light sources _{9 ,} 92, and 93 in the headlamp housing 1.

Since the optical axis of the position lamp light source ₉ is set within the range in which the light from the position lamp light sources ₉ , _{9 1} , 92, 94, 95 is transmitted forward through the inner lens 11, the number of parts is increased. It is possible to reduce the number and make the structure more compact.
Further, by giving the inner lens 11 a refractive property, not only the inner lens portion but also the headlamp reflector 5 can emit light, and the design can be improved. Instead of shining pinpoint, it can be dimly lit.
Since the surface of the inner lens 11 is formed in a shape continuous with the surface of the reflective surface 5A of the headlamp reflector 5, there are no notches or openings in a part of the headlamp reflector 5, and the periphery of the light source. Since there are no gaps or steps with the reflector, the appearance does not deteriorate.

The present invention is not limited to the above embodiment. For example, in the above embodiment, the structure of the headlight on the left side of the vehicle has been described, but the structure of the headlight on the right side of the vehicle has been described. , It is configured in a symmetrical shape with the structure of the headlight on the left side. Further, the position lamp light source 9, 9 ₁ , 9 ₂ , 9 ₃ , 9 ₄ , 95 may be an LED other than the valve, and the position lamp light source 9, 9 ₁ , 92, 9 ₃ , _{9 4} , _{9 5} may be used. The optical axis of the headlamp reflector 5 can be arbitrarily set from a range of transmitting the light source to the front of the headlamp reflector 5 through the inner lens 11 to a range of an inclination angle of 90 degrees to the left and right. In addition, it goes without saying that it can be appropriately modified and implemented within the technical scope of the present invention.
