Description

  The present invention belongs to the technical field of a vehicle housing to be mounted on a vehicle door.

  In general, this type of housing is known in which an opening is formed toward the front side of the door mirror in the vehicle traveling direction and is incorporated as a side turn signal (side turn lamp). And these side blinkers can secure a legal direction indication function by irradiating light from the end of the door mirror opposite to the vehicle body side toward the rear of the vehicle. A door mirror having a function of emitting light toward the front in the vehicle traveling direction is known, and there is a door mirror that improves the design of the entire door mirror.

As such a side blinker, for example, a light guide for irradiating light rearward from the projecting side end of the door mirror is disposed along the outer surface of the side blinker housing. There is known a configuration in which light is emitted toward the vehicle traveling direction side of the door mirror by covering the outer surface of the door mirror with a light emitting film and causing the light emitting film to emit light with electric energy. In this case, an outer plate is further attached to the outer surface of the light-emitting film, so that the light-emitting film is protected and light of the light-emitting film is transmitted through the outer plate and emitted to the outside. (For example, refer to Patent Document 1).
However, the intended Patent Document 1, the structure is not only complicated, the light emitting film is like planar those provided for covering the outer surface side of the light guide, thus inevitably visually perceived depth It was inferior in design property because it became a light emission without.

Therefore, for example, the light source for irradiating the front in the vehicle traveling direction is exposed from the inner housing, and the light source mounting surface formed on the inner housing is configured to have a three-dimensional unevenness, and further the film forming process is performed on the inner housing In order to reflect the light from the light source, it has been proposed to perform a three-dimensional irradiation with a depth (see, for example, Patent Document 2).

JP 2000-103287 A JP 2004-276768 A

Although this was excellent in design and high evaluation because it can irradiate three-dimensionally with respect to the front in the vehicle traveling direction, the light source that illuminates the front is exposed from the inner housing. The illumination becomes brighter than the surroundings and the light is unevenly scattered, resulting in a lack of uniformity, and the three-dimensional inner housing can also be seen through the outer lens. There is a demand for the appearance of a housing that can be irradiated uniformly while performing a three-dimensional irradiation with a sense, and there is a problem that the present invention does not solve.

Each of the first light sources 6a has a function as a direction indicator for instructing the vehicle to travel in the left-right direction. The first light source 6a irradiates and visually recognizes the lateral and lateral sides of the vehicle body. It meets the above standards.

  On the lamp base end 3b side, a second light source (in the present embodiment, constituted by one light emitting diode) 6b of the present invention is located between the outer housing 4 and the outer lens 5. In this embodiment, the second light source 6b is disposed on the base end side of the lamp base end portion 3b and radiates light toward the lamp outer end portion 3d. It is installed.

As shown in FIGS. 4 and 5, 7 and 8 are first and second light control bodies of a box that internally reflects the light from the second light source 6 b. Since the first and second light control bodies 7 and 8 have the same structure, the first light control body 7 will be described here, and a detailed description of the second light control body 8 will be omitted. The first light control body 7 is a long object in the left-right direction, and a base end side surface 7b is formed on the base end portion 7a of the first light control body 7, and the front-back direction of the base end side surface 7b is formed. A light irradiation hole 7c for mounting the second light source 6b so as to look into the inner surface of the first light control body 7 is formed in a semicircular cutout in the center portion. And the bottom part located under the base end side surface 7b is opened to form an opening 7d. And the site | part which opposes the base end side surface 7b on both sides of the opening part 7d becomes the inclined shape which inclined so that it might become high toward the other end part 7e of the 1st light control body 7, and inside this inclined part Is formed with a first reflecting surface 7f that reflects light from the second light source 6b toward the upper side of the base end surface 7b. A portion of the upper surface of the first light control body 7 adjacent to the base end side surface 7b is inclined so as to become higher from the base end side surface 7b toward the other end portion 7e. On the inner side, a second reflecting surface 7g that receives light reflected by the first reflecting surface 7f and reflects it in the longitudinal direction of the first light control body 7 is formed.
The first reflecting surface 7f and the second reflecting surface 7g are embodiments of the first light reflecting portion of the present invention.

  Further, a portion of the second reflecting surface 7g from the end on the other end 7e side to the other end 7e of the first light control body 7 is inclined so as to be lowered toward the other end 7e. A third light reflecting portion of the present invention is formed on the inner side of the inclined portion and reflects the light reflected by the second reflecting surface 7g toward the lower direction of the first light control body 7. A reflection surface 7h is formed. The third reflection surface 7h is inclined more gently than the second reflection surface 7g, and the inclination angle is set so that the reflected light from the second reflection surface 7g is reflected downward.

  On the other hand, from the end on the other end 7e side of the first reflecting surface 7f toward the other end 7e, a bottom surface portion 7j is formed in a plate shape in the horizontal direction, and at the center in the front-rear direction of the bottom surface portion 7j. As shown in FIG. 6, a strip-shaped light emission hole 7i is cut out in the left-right direction.

  The inner side surface of the first light control body 7 has, for example, a textured shape so as to scatter light, and a film is formed thereon to form a light scattering reflection surface. Therefore, the light emitted from the second light source is reflected while being scattered on the inner surface of the first light control body 7.

  As described above, since the first light control body 7 and the second light control body 8 have the same shape, the second light control body 8 is abutted in a direction in which the top and bottom of the first light control body 7 are reversed. When assembled, as shown in FIG. 7, the semicircular light irradiation hole 7 c formed in the base end portion 7 a of the first light control body 7 and the base end portion 8 a of the second light control body 8 are formed. The light irradiation hole 8c is abutted to form a perfect circular hole, and the second light source 6b is assembled here, so that the light from the second light source 6b is emitted from the first light control body 7 and the second light control body 8. Light is irradiated toward the inner surface.

  In the state where the first light control body 7 and the second light control body 8 are assembled in this way, the light from the second light source 6b and the first reflection surface 7f formed on the first light control body 7 and the first light control body 7b. The first reflective surface 8f formed on the two-light controller 8 is irradiated, the light irradiated on the first reflective surface 7f is reflected on the second reflective surface 7g, and the light irradiated on the first reflective surface 8f is second reflected. The light reflected by the surface 8g is reflected on the second reflecting surface 7g, and then incident on the third reflecting surface 7h. The reflected light on the second reflecting surface 8g is reflected downwardly from the first light control body 7. The light enters the three reflecting surfaces 8h and is reflected upward in the second light control body 8. Further, the reflected light is emitted from a light emission hole 7 i formed in the first light control body 7 and a light emission hole 8 i formed in the second light control body 8.

  On the other hand, reference numeral 9 denotes an inner lens that is assembled between the outer housing 4 and the outer lens 5 as shown in FIGS. The inner lens 9 is formed with a groove portion 9a protruding in a groove shape toward the outer housing side at an intermediate portion in the vertical direction. The first light control body 7 and the second light control body are respectively formed above and below the groove portion 9a. 8 is arranged. The inner lens 9 is formed on the outer lens 5 side so that the outer housing 4, the second light source 6 b, the first light control body 7, and the second light control body 8 pass through the outer lens 5. And cannot be seen from the outside. The groove 9a formed in the inner lens 9 has, for example, a textured surface so that light is reflected while being scattered, and a film is further formed thereon to form the third light reflection according to the present invention. The inner lens reflecting surface 9b which is the embodiment of the portion is configured.

On the back surface (side surface of the outer housing) of the groove portion 9a, a projection 9c is formed in the vertical central portion that protrudes in a vertical cross-section toward the outer lens side (see FIG. 9A). Light passage holes 9d and 9e through which light emitted from the light emission holes 7i and 8i formed in the first and second light control bodies 7 and 8 respectively pass are formed in the upper and lower side surfaces of the groove 9a. .
In addition, the shape of the projection part 9c does not need to be a bowl shape, and may be configured to bulge to the outer lens side in a semicircular cross section as shown in FIG. 9B.

  The inner lens 9 is disposed so that the groove portion 9a fills the space S formed between the first light control body 7 and the second light control body 8. At this time, the inner lens 9, The light control body 7 and the second light control body 8 include light emission holes 7 i and 8 i formed in the first light control body 7 and second light control body 8 and light passage holes 9 d and 9 e formed in the inner lens 9. The light is emitted from the light emitting holes 7i and 8i through the light passing holes 9d and 9e formed in the inner lens 9, so that the inner lens reflecting surface 9b and the protrusion are formed. The portion 9 c is irradiated, and light from the inner lens reflecting surface 9 b and the protruding portion 9 c is reflected in the direction of the outer lens 5.

  Incidentally, when the inner surface of the first light control body 7 and the second light control body 8 and the groove portion 9a of the inner lens 9 are formed as film-formation light scattering surfaces, the surface where light enters is light such as wrinkles in this embodiment. It is formed by forming a scattering surface and further forming a film (in this case, the material forming the first and second light control bodies and the inner housing may be translucent or non-translucent). The first light control body 7, the second light control body 8, and the inner lens 9 are formed of a translucent resin material, and the light incident surface is a light scattering surface, and the back surface is formed. You may make it become a reflective surface, and you may comprise a back surface as a light-scattering reflective surface.

  In the first embodiment of the present invention configured as described above, a first light source 6a and a second light source 6b are incorporated in a lamp 3 incorporated in the mirror housing 2 as a lamp unit. 6a serves as a legal function as a left and right traveling direction indicator of the vehicle, and the second light source 6b functions as a light source that illuminates the front in the vehicle traveling direction to improve visibility from the front. Here, the second light source 6b irradiates the inner side surfaces of the first and second light control bodies 7 and 8 without directly irradiating the front in the vehicle traveling direction. Here, the light from the second light source 6b is reflected by the first reflection surface 7f formed on the first light control body 7 and the first reflection surface 8f formed on the second light control body 8, and further the second reflection surface. 7g, reflected by the second reflecting surface 8g, and further reflected in the vertical direction by the third reflecting surface 7h, the third reflecting surface 8h, and reflected by the inner lens formed on the inner lens 9 from the light emitting holes 7i, 8i. The light is directed toward the surface 9b and the protrusion 9c, and light is directed toward the outer lens 5 by the inner lens reflecting surface 9b and the protrusion 9c, and light is emitted to the outside through the outer lens.

  Therefore, the light from the outer lens 5 is not emitted directly from the second light source, but is emitted to the outside as reflected light that is reflected a plurality of times by the first and second light control bodies 7 and 8 and the inner lens 9. Therefore, it becomes light with soft uniformity and can be a side blinker with high design.

  Moreover, since the inner surfaces of the first and second light control bodies 7 and 8 and the outer lens side surface of the inner lens 9 are all light scattering surfaces and light reflecting surfaces, the light from the second light source 6b is Since the light is reflected while being sufficiently scattered, the light visually recognized from the outside can be uniform with no light unevenness.

  Then, only the reflected light from the inner lens reflecting surface 9b of the inner lens 9 is visually recognized from the outside, and this makes it possible to obtain strip-shaped light with a clear outline.
