Description

  The present invention includes a headlamp body of a four-lamp system that includes a headlamp body that is lit when a traveling beam is provided at the center of the vehicle, and a headlamp body that is illuminated when a traveling beam and a passing beam are present outside. About.

  Conventionally, in a vehicle, a four-lamp vehicle having a headlamp body that is turned on when the traveling beam is provided at the center side of the vehicle and a headlamp body that is turned on when the traveling beam and the passing beam are provided outside. Some headlamps are used.

For example, JP-A-5-307901 includes a first headlamp body that is lit to form a traveling beam and a second headlamp body that is lit to form a traveling beam and a passing beam. A technique is disclosed in which a shade for reducing the amount of light is provided at a predetermined position in the second headlamp body to optimize the amount of light when the traveling beam is used.
JP-A-5-307901

  However, the above-described headlamp disclosed in Patent Document 1 is intended only to improve the visibility in front of the vehicle, and does not improve the visibility on the side of the vehicle. That is, particularly when the vehicle turns, etc., it is required that the visibility on the side of the vehicle in the turning direction is good, but the above-mentioned Patent Document 1 improves the visibility on the side of the vehicle. is not.

  The present invention has been made in view of the above circumstances, and in particular, has a simple structure without using a new light source, a driving mechanism, etc., and greatly increases the visibility on the side of the vehicle while effectively using the light amount of the conventional light source. An object of the present invention is to provide a vehicle headlamp that can be improved to greatly improve the visibility when turning or when an obstacle jumps out.

  The present invention is directed to a first headlamp body disposed on the center side of a vehicle that reflects light from a first light source by a first reflector and projects it forward to form a traveling beam, The light source light from the second light source is reflected by the second reflector and projected forward through the cylindrical member to form at least a passing beam. In a vehicle headlamp including a second headlamp body, a side projection hole for projecting light to the side of the tubular member is formed on a side surface of the tubular member on the first headlamp body side. At the same time, a side projection reflector is formed which extends the vehicle central side edge of the first reflector forward and reflects the light from the side projection hole toward the vehicle side.

  According to the vehicle headlamp according to the present invention, the visibility on the side of the vehicle is greatly improved, particularly with a simple structure without using a new light source, a drive mechanism, or the like, while effectively using the light amount of the conventional light source. Thus, it is possible to greatly improve the visibility when turning or jumping out of an obstacle.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show an embodiment of the present invention, FIG. 1 is a schematic view showing a front headlamp of a vehicle, FIG. 2 is a sectional view showing an internal structure of a left headlamp, and FIG. It is explanatory drawing of the spread of light distribution.

  In FIG. 1, reference numeral 1 denotes a vehicle, and headlamps 2 </ b> L and 2 </ b> R are provided on the left and right sides of the vehicle 1, respectively.

  Each of the headlamps 2L and 2R is provided with a first headlamp main body 3 on the center side of the vehicle 1 and adjacent to the first headlamp main body 3 on the outside of the vehicle 1 with a second headlamp main body. In addition, a hazard lamp 5 is provided outside the second headlamp body 4 and is integrally covered with a lens cover 6.

  The structure of the headlamps 2L and 2R will be described with reference to FIG. 2 by taking the left headlamp 2L as an example.

  The first headlamp main body 3 disposed on the center side of the vehicle 1 includes a first light source 7 and a first reflector 8 that reflects light from the first light source 7 forward. It is configured and is lit when forming a traveling beam.

  The second headlamp body 4 disposed outside the vehicle 1 adjacent to the first headlamp body 3 has a second light source 9 and the light from the second light source 9 forward. A second reflector 10 that reflects, a cylindrical member 11 that extends forward from the front edge of the second reflector 10, and a projection lens 12 that is fixed to the front end of the cylindrical member 11. It is turned on when a traveling beam and a passing beam are formed.

  The cylindrical member 11 of the second headlamp main body 4 is formed with a substantially circular side projection hole 13 for projecting light to the side of the cylindrical member 11 on the side surface on the first headlamp main body 3 side. Has been.

  Moreover, the vehicle center side edge part of the 1st reflector 8 of the 1st headlamp main body 3 is extended ahead, and is for the side part projection which reflects the light from the side part projection hole 13 toward a vehicle side. A reflector 14 is formed.

  The first headlamp main body 3, the second headlamp main body 4, and the hazard lamp 5 are provided with extensions 15 around the lamps and between the lamps. In addition to being prevented, the decorativeness is improved. The extension 15 is provided between the first headlamp body 3 and the second headlamp body 4 so as not to interfere with the projection light directed from the side projection hole 13 to the side projection reflector 14. A gap 16 is formed.

  In the headlamps 2L and 2R configured as described above, only the second headlamp main body 4 is lit when passing the beam.

  For this reason, the second light source 9 of the second headlamp body 4 is turned on, and the light from the second light source 9 is reflected forward by the second reflector 10, and passes through the cylindrical member 11 and the projection lens 12. Is projected forward.

  Further, as shown by the arrow in FIG. 2, light is projected from the tubular member 11 toward the side projection reflector 14 of the first headlamp main body 3 through the side projection hole 13. Reflected by the side projection reflector 14 and projected to the side of the vehicle.

  Since the side of the vehicle is illuminated by the light from the side projection holes 13, for example, as shown in the spread of light distribution in FIG. 3, the spread of light distribution of the headlamps 2L and 2R is the conventional spread (see FIG. Compared to (shown by a broken line in 3), the side can be illuminated widely. That is, according to the present embodiment, the visibility on the side of the vehicle is greatly improved with a simple structure without using a new light source, a drive mechanism, or the like, while effectively using the light amount of the conventional light source. Thus, the visibility at the time of turning or jumping out of an obstacle can be greatly improved.

  On the other hand, in the case of a traveling beam, in addition to the second headlamp body 4 described above, the first headlamp body 3 is also lit, and the light from the first light source 7 is reflected forward by the first reflector 8. And projected forward.

  Even during this traveling beam, the second headlamp body 4 is lit in the same way as during the passing beam, so the visibility on the side of the vehicle is greatly improved, and visibility during turning, jumping out of obstacles, etc. Can greatly improve the performance.

  In the present embodiment, the side projection hole 13 of the cylindrical member 11 is simply formed by forming a hole, but as shown by the broken line in FIG. A guide portion 20 for guiding the light in the cylindrical member 11 to the side projection reflector 14 may be provided in the portion.
