Description

  The present invention relates to a vehicle headlamp structure in which a headlight bulb and a position bulb are configured as separate rooms.

Conventionally, a high beam dedicated reflector is arranged in front, and a low beam dedicated reflector is arranged behind it, and the front projected area of the low beam dedicated reflector is made larger than the front projected area of the high beam dedicated reflector. A vehicle headlight structure hidden by a high beam dedicated reflector is known. With such a structure, an effect is obtained that the low beam bulb cannot be seen from the outside and the light emitting surface looks substantially donut-shaped (see, for example, Patent Document 1).
JP 2002-216509 A

  When a structure that is attached so that the low beam bulb itself cannot be seen from the front side of the vehicle body as in the conventional example is applied to a position valve that originally has a low light quantity, the direct light from the bulb cannot be used, and the light quantity is reduced. Therefore, it is not preferable for fulfilling the function of displaying the position.

  The present invention has been made in view of the above-described circumstances, and makes it difficult to see the position bulb from the outside, makes it possible to obtain a novel and design effect on the light emitting surface, and even a bulb with a small amount of light. An object of the present invention is to provide a vehicle headlamp structure capable of ensuring a sufficient amount of light and sufficiently functioning as a position light.

In order to solve the above-described problems, the present invention is provided with a headlight bulb, a position bulb, a housing for housing the headlight bulb and the position bulb, a front of the headlight bulb and the position bulb, and transmits light. The housing includes a headlight reflector that reflects light from the headlight bulb, and a position bulb reflector that is a separate chamber through the headlight bulb reflector and the partition. In the vehicle headlamp structure, the partition portion extends to the lens, and a vertical wall portion that is positioned in front of the position valve and functions as a reflector of the position valve is provided integrally with the housing. Along the plane perpendicular to the longitudinal direction of the vehicle, The housing behind the position valve is provided with a reflector portion, and the position valve is partially covered by the vertical wall portion when viewed from the front, and is arranged in such a manner that the upper portion of the position valve is exposed. Features.
According to this configuration, the light of the position bulb can be blocked by the partition portion and the vertical wall portion provided integrally with the housing, and the light emitting surface of the position bulb as seen from the front of the vehicle body is not noticeable. Become.

Further, the vertical wall portion may be formed so as to be inclined upward in the vehicle body relative to the horizontal direction.
According to this structure, the light of the position valve irradiated to the front of the vehicle body can be blocked by the vertical wall portion. On the other hand, the vertical wall portion can be formed in the mold dividing direction.

  Furthermore, you may make the upper end position of the said vertical wall part the same height as the valve center position of the said position valve.

Moreover, you may form the light-shielding part which is the space which shields light between the said vertical wall part and the said partition part.
According to this configuration, the light of the headlight bulb and the light of the position bulb can be more clearly partitioned by the space that blocks the light.

Further, the position valve may be accommodated in the position valve reflector portion with its long axis extending in the vertical direction.
According to this structure, the reflector located in the back surface of a position valve can be used effectively.

Further, the lens may be diamond cut at a portion in front of the vertical wall portion.
According to this configuration, the vertical wall portion can be made inconspicuous.

Still further, a labyrinth-structured ventilation hole can be provided in the position valve reflector.
According to this configuration, it is possible to make the lens in front of the position valve difficult to be fogged due to condensation or the like.

In the vehicle headlamp structure according to the present invention, the partition portion extends to the lens, and the vertical wall portion located in front of the position valve is provided integrally with the housing. By dividing the light emitting surface of the position bulb by the partitioning portion and blocking a part of the light of the position bulb by the vertical wall portion, the light emitting surface of the position light can be elongated to enhance the design and commercial properties. Further, since it is not necessary to provide a cover at a part of the front of the lens of the position valve or to provide a reflector or a separate plate for the lens, the alignment of the lens and the cover is not complicated and the number of parts does not increase.
In addition, because the position valve itself is partially exposed, part of the direct light from the position valve can be used, and the axis of the position valve is along a plane perpendicular to the longitudinal direction of the vehicle. Since the reflector part is provided in the housing, the light of the part where the position valve is hidden behind the vertical wall part can also be reflected and irradiated to the outside.

  Further, since the vertical wall portion is formed so as to be inclined upward toward the front of the vehicle body with respect to the horizontal direction, the position light is blocked by blocking the light of the position valve irradiated toward the front of the vehicle body by the vertical wall portion. The light emitting surface can be elongated to enhance the design and commercial properties. Further, by forming the vertical wall portion in the mold dividing direction, the vertical wall portion can be formed integrally with the housing without the need for post-processing, and the manufacturing cost can be reduced.

  Further, since a light shielding portion that is a space that blocks light is formed between the vertical wall portion and the partition portion, the light from the headlight bulb and the light from the position bulb are shielded from light that is a space that blocks light. The section can be partitioned more clearly, and the light emitting surface of the position light can be seen more clearly and elongated.

  In addition, since the position valve is accommodated in the position valve reflector portion with its long axis extending in the vertical direction, light can be reflected on the entire surface of the reflector located on the back surface of the position valve. Thereby, compared with the case where a position valve is accommodated along the front-back direction, the emitted light amount can be increased. Furthermore, an irradiation area can be increased using a reflector on the back surface.

  Furthermore, since the lens is diamond-cut at a portion in front of the vertical wall portion, appearance can be improved by making the vertical wall portion inconspicuous. In addition, the light emitting surface of the position light can be shown more clearly and elongated.

  Furthermore, since the position valve reflector is provided with a labyrinth-structured ventilation hole, it is possible to improve the function of the position light by making it difficult for the lens in front of the position valve to be fogged by condensation or the like.

More specifically, each of the upper side portion 66A and the lower side portion 66B of the housing 66 has a V-shape that is inclined obliquely upward from the central portion toward both sides. The upper end of each of the portion 66A and the lower side portion 66B is inclined obliquely downward from the upper end so as to be connected linearly. The outer shape of the housing 66 substantially matches the outer shape of the headlamp 25 as shown in FIG.

As shown in FIG. 3, the housing 66 has left and right partition portions 72 extending from the side portions 66C on both sides toward the upper side portion 66A. In addition, left and right vertical wall portions 74 are formed in the housing 66 so as to extend from the left and right partition portions 72 along the upper side portion 66A substantially parallel to the outside of the vehicle body.
The housing 66 is divided into respective chambers by the partition portion 72 and the vertical wall portion 74. More specifically, as shown in FIG. 3, the housing 66 includes a headlight bulb reflector 100 for reflecting the light from the headlight bulb 68 toward the front of the vehicle body, and the light from the position bulb 70 to the front of the vehicle body. There are provided two position bulb reflectors 150 for reflecting the light, and a headlight bulb 68 and a light shielding portion 200 for blocking the light from the position bulb 70.

  As shown in FIG. 3, the headlight bulb reflector unit 100 has an outer edge portion defined by an upper side portion 66A, a lower side portion 66B, a side side portion 66C, and a partition portion 72. The distance from the light valve 68 to the outer edge is substantially equal. Further, as shown in FIGS. 5 and 6, the front end of the partition 72 at the front of the vehicle body extends to a position in contact with the inner surface of the lens 64 with the lens 64 attached thereto, and is a headlight bulb reflector. The internal space of the section 100 and other internal spaces are partitioned by the partition portion 72 so as to be separate rooms.

  On the other hand, as shown in FIG. 3, the surface of the housing 66 of the headlight bulb reflector 100 is provided with a plurality of bending lines 102 extending in the vehicle body vertical direction at intervals in the vehicle width direction. ing. This surface is a reflector 104 that reflects the light of the headlight bulb 68 toward the front of the vehicle body. By providing the plurality of bending lines 102, the reflecting surface of the reflector 104 can be configured as an assembly of a plurality of planes, and it is easier to collect light toward the front of the vehicle body and the head when viewed through the transparent lens 64. The appearance of the light valve reflector 100 is improved.

  As shown in FIG. 4, the housing 66 has an arm shape that is recessed toward the rear of the vehicle body (the right direction in FIG. 4) in the headlight bulb reflector unit 100. A substantially vertical plane is formed on the arm-shaped bottom portion 106 (right side portion in FIG. 4), and a headlight bulb 68 is detachably attached to the plane in the longitudinal direction of the vehicle body.

  As shown in FIG. 3, the position valve reflector 150 has an outer edge portion defined by a partition 72, an upper side 66A, a side side 66C, and a vertical wall 74. It is formed in an elongated shape that rises upward. Further, as shown in FIGS. 6 and 7, the front end portion of the vertical wall portion 74 in the front of the vehicle body extends to a position almost in contact with the inner surface of the lens 64 with the lens 64 attached, and is used for the position valve. The internal space of the reflector unit 150 and the other internal space are divided into separate rooms by the vertical wall unit 74 and the partition unit 72 described above.

  Further, as shown in FIG. 6, the housing 66 is recessed obliquely downward and rearward of the vehicle body at an inclination of about 15 ° with respect to the vertical line P in the position valve reflector 150. The vertical wall portion 74 and the upper wall surface 152 of the position valve reflector portion 150 are formed so as to be parallel to the direction X of the depression and to be inclined upward in the horizontal direction with respect to the vehicle body. A plane that is substantially orthogonal to the direction X of the depression is formed at the bottom 156 of the depression, and on this plane, the long axis of the position valve 70 (the same axis as the depression direction X in FIG. 6) extends along the depression direction X. It is attached detachably. That is, the inner surface of this recess serves as the reflector 154 of the position valve 70. In particular, since the position valve 70 is not attached to the reflector 154 located behind the position valve 70, the entire surface functions as a reflector, so that the amount of light irradiated to the front of the vehicle body can be increased. it can.

  As shown in FIG. 6, the recess of the position valve reflector 150 can be easily formed by molding the vertical wall 74, the upper wall 152, and the bottom 156 by removing the molding die in the recess direction X. Can be formed. That is, the housing 66 is integrally molded with resin or the like, and the mold is divided and pulled out in three directions 174, which are the same as the front direction 170, the rear direction 172, and the recess direction X shown in FIG. Can be molded.

  When the position valve reflector 150 is viewed from the front side of the vehicle body, the lower portion of the position valve 70 is hidden by the vertical wall 74 as shown in FIG. About half is visible in front view. Therefore, since only the bulb sphere extending upward in the columnar shape is visible, the reflector axis on the back is not perforated while the bulb axis is viewed as if extending toward the front. It can be secured sufficiently. More specifically, the vertical wall portion 74 is inclined upward toward the front of the vehicle body so as to be at the same height as the center position (light emitting portion) of the position bulb 70.

  As shown in FIG. 3, the light shielding part 200 is defined by a side part 66C, a partition part 72, and a vertical wall part 74, and has a substantially triangular shape when viewed from the front. As shown in FIG. 6, the light-shielding portion 200 has a cross-sectional shape in which the partition portion 72 extending forward of the vehicle body and the vertical wall portion 74 having an inclination as described above have a triangular shape. The light shielding part 200 is shielded from light from the headlight bulb 68 and the position valve 70 by the partition part 72 and the vertical wall part 74, so that the light does not enter the light shielding part 200. That is, when the light shielding part 200 is viewed from the front of the vehicle body, the light shielding part 200 looks dark.

  As shown in FIG. 2, a diamond cut 65 is applied to the lens 64 positioned in front of the light shielding unit 200. The diamond cut 65 is formed in the same triangular shape as the light shielding portion 200. By applying this diamond cut 65, the light passing through the diamond cut 65 portion of the lens 64 can be diffusely reflected, and the light shielding portion 200 can be seen darker when viewed from the front of the vehicle body. The portion 74 is made inconspicuous in design. Here, the diamond cut referred to in this specification means a lens provided with a plurality of irregularities on the surface or inner surface of the lens 64. The plurality of projections and depressions are of such a degree that light passing therethrough can be diffusely reflected, and may be formed by integral molding or cut by post-processing.

The housing 66 has various shapes based on its function.
As shown in FIG. 5, a wiring support portion 182 is integrally formed in the housing 66 on the rear side of the headlight bulb reflector portion 100. The wiring 180 is connected to the headlight bulb 68, the position bulb 70, and the like. The wiring support portions 182 are provided symmetrically at two locations on the left and right sides of the housing 66 so that the wiring 180 can be pushed from above without being used with a screw or the like and can be clapped.

  The headlamp 25 can adjust (aim) the direction of the headlight in three stages in the vertical direction. That is, as shown in FIG. 5, a support portion 190 that protrudes toward the rear of the vehicle body is integrally provided on the upper portion of the housing 66, and the housing 66 main body is supported by the support portion 190. On the other hand, a stay pipe 192 extending toward the front of the vehicle body is provided on the vehicle body frame side, and a support portion 190 is hooked through a rubber 198 inserted into the stay pipe 192.

  Further, as shown in FIG. 4, an adjusting portion 194 for aiming is integrally formed on the lower side of the housing 66, and an adjusting nut 196 for fixing the housing 66 is formed on the adjusting portion 194. The position of the aiming can be adjusted by loosening the adjustment nut 196. Further, a gap is provided between the front top cover 37B and the lens 64 so that the front top cover 37B and the lens 64 do not interfere with each other during aiming adjustment.

Further, as shown in FIG. 7, a ventilation hole 153 that communicates the inside and the outside of the position valve reflector 150 is formed integrally with the housing 66 on the upper wall surface 152 of the position valve reflector 150. Yes. The ventilation hole 153 protrudes in a pipe shape from the upper wall surface 152 to the rear part of the housing 66, and an air hole 158 is formed therein. A labyrinth pipe 160 is attached to the tip of the ventilation hole 153 to prevent intrusion of rainwater and dust. The labyrinth pipe 160 has a structure in which the flow path to the outside air is curved to the left and right so that the lens 64 positioned in front of the position valve reflector 150 is not fogged due to condensation or the like.
The headlight bulb reflector 100 also has a similar structure so that the interior thereof is not fogged.

  According to the vehicle headlamp structure according to the embodiment of the present invention, the front end of the partition 72 extends to the inner surface of the lens 64 and is positioned in front of the position valve 70 to serve as the reflector 154 of the position valve 70. Since the functioning vertical wall portion 74 is provided integrally with the housing 66, the partition wall 72 and the vertical wall portion 74 provided integrally with the housing 66 block the light of the headlight bulb 68 and the position bulb 70, thereby preventing the position. It is possible to elongate the light emitting surface of the light and enhance the design and commercial properties. Further, since it is not necessary to provide a cover in front of the lens 64 of the position valve 70 or to provide a reflector or a separate plate for the lens, the lens and the cover are complicated to be combined and the number of parts is increased. Absent.

  Further, since the position valve 70 itself is partially exposed, a part of the direct light of the position valve 70 can be used, and the axis X of the position valve 70 extends along the upper wall surface 152 perpendicular to the front-rear direction of the vehicle. 74 and the housing behind the position valve 70 are provided with the reflector portion which is the upper wall surface 152, so that the position valve 70 can also reflect the light hidden in the vertical wall portion 74 to irradiate the outside. .

  Further, since the vertical wall portion 74 is formed so as to be inclined upward in the horizontal direction with respect to the horizontal direction, the position light is blocked by blocking the light of the position valve 70 irradiated to the front of the vehicle body by the vertical wall portion 74. The light emitting surface can be elongated to enhance the design and commercial properties. Further, by forming the vertical wall portion 74 in the mold dividing direction, the vertical wall portion 74 can be formed integrally with the housing 66 without the need for post-processing, and the manufacturing cost can be reduced.

  Further, since the upper end position of the vertical wall portion 74 is set to the same height as the valve center position of the position valve 70, the light emitting surface of the position valve 70 viewed from the front of the vehicle body becomes inconspicuous, and the position light The light emission intensity of the light emitting surface can be made uniform. As a result, the spherical shape of the position valve 70 is not conspicuous, and the appearance can be improved.

  In addition, since the light shielding portion 200 that is a space for blocking light is formed between the vertical wall portion 74 and the partition portion 72, the light from the headlight bulb 68 and the light from the position bulb 70 are transmitted by the light shielding portion 200. It can be partitioned more clearly, and the slender shape of the position light can be seen more clearly.

  Further, since the position valve 70 is accommodated in the position valve reflector 150 with the long axis X extending in the vertical direction, light can be reflected on the entire surface of the reflector 154 located on the back surface of the position valve 70. Thereby, the emitted light quantity can be increased compared with the case where the position valve 70 is accommodated along the front-rear direction. Furthermore, an irradiation area can be increased using the reflector 154 on the back surface.

  Further, since the lens 64 is provided with a diamond cut 65 at a portion in front of the vertical wall portion 74, appearance can be improved by making the vertical wall portion inconspicuous. In addition, the light emitting surface of the position light can be shown more clearly and elongated.

  Furthermore, since the labyrinth pipe 160 having the labyrinth structure is provided in the position valve reflector 150, the function of the position light can be improved by making the lens 64 in front of the position valve 70 difficult to be fogged by condensation or the like. .

While the embodiments of the present invention have been described above, various modifications and changes can be made based on the technical idea of the present invention.
In the present embodiment, the light-shielding portion 200 and the diamond cut 65 have a substantially triangular shape. However, by forming the vertical wall portion 74, the position light is elongated and the outer shape thereof can be seen clearly. As long as there is any other shape, for example, a shape having corners of a square or more may be used. Moreover, it may be a rounded shape instead of a polygon.

  Further, the upper end position of the vertical wall portion 74 is set to the same height as the valve center position of the position valve 70, but if the light quantity of the position valve 70 can be sufficiently secured, it is higher than the valve center position, that is, the position The light emitting surface of the bulb 70 may be further hidden. As a result, the light emission surface of the position valve 70 viewed from the front of the vehicle body can be made less noticeable, and the light emission intensity of the light emission surface of the position light can be made more uniform. As a result, the spherical shape of the position valve 70 is not conspicuous, and the appearance can be improved.
