Description

  The present invention relates to a vehicle headlamp that is mounted on the front surface of a vehicle in which a lamp unit is accommodated in a space formed by a housing and a translucent cover that covers an opening on the front surface of the housing.

  In recent years, vehicle headlamps (so-called LED headlamps) using light-emitting diodes (hereinafter referred to as LEDs) as light sources are known. Thus, when the light source is an LED, there is an advantage that less power consumption is required compared to a conventional halogen headlamp or the like in which the light source is a halogen lamp.

  In the case of a halogen lamp, since it has a filament, light is radiated in all directions around it. However, in the case of an LED, since the irradiation range is narrow, there is a feature that irradiation directivity is high. For this reason, the reflector that reflects the light of the light source can also be configured in a compact manner. Particularly, when a plurality of lamp units are provided in the lamp housing, the degree of freedom of arrangement increases and the degree of freedom in design can be improved. There is also.

  Patent Document 1 below discloses a projector in which a plurality of so-called projector-type lamp units each including an LED light source, a reflector, and an inner lens are provided in the lamp housing, taking advantage of the LED headlamp as described above. .

  Also, in recent years, the so-called adaptive front-lighting system (Adaptive Front-lighting) that changes the irradiation direction of the lamp unit according to the running state of the vehicle (for example, interlocking with the steering operation or the monitoring result outside the vehicle). System (hereinafter abbreviated as AFS) is also known.

  Here, it is conceivable to employ AFS in a vehicle headlamp having a plurality of light sources (lamp units) in a lamp housing. In this case, a drive unit (motor, drive mechanism, etc.) for changing the irradiation direction of the lamp unit is shared by a plurality of lamp units arranged in parallel in the vehicle width direction, and the direction of the lamp unit is changed integrally. With this configuration, it is not necessary to provide an AFS drive unit for each of the plurality of lamp units, which is considered to be advantageous in terms of cost. Japanese Patent Application Laid-Open Publication No. 2004-228561 discloses a structure in which a plurality of lamp units are rotated by a common drive unit.

Japanese Patent No. 4102240 Japanese Patent No. 4908282

  However, as described above, when the AFS is adopted in the vehicle headlamp having a plurality of lamp units, the lamp unit rotated by the drive unit and the lamp housing as the headlamp constituent member do not interfere with each other. It is necessary to. Therefore, it is conceivable to arrange the lamp housing at a position far away from the lamp unit. In this case, however, the size of the lamp unit increases the size of the entire vehicle headlamp.

  In addition, the vehicle headlamp also has a role as a design portion of the front portion of the vehicle. In recent years, there has been a demand for providing a decorative member as a headlamp component in the lamp housing because of the design needs of the vehicle. There is. In view of this, it is conceivable to employ an AFS in which a lamp housing for a high beam and a lamp housing for a low beam are juxtaposed in the vehicle width direction, and further, the decorative member is juxtaposed in the vehicle width direction.

  In this case, in order to prevent the lamp unit and the decorative member from interfering with each other, it is conceivable that the decorative member is arranged at a position far away from the lamp unit. As a result, the overall size of the vehicle headlamp is increased.

  For this reason, when adopting AFS in a vehicle headlamp having a plurality of lamp units, from the viewpoint of avoiding an increase in the size of the vehicle headlamp, the lamp unit and the headlight constituent members (lamp housing and decorative member) It is necessary to set the rotation center and the rotation locus appropriately on the lamp unit side so that they do not interfere with each other.

  Further, when the LED headlamp is adopted, as described above, although power consumption is small, there is a demerit that the LED is weak against heat, and it is necessary to provide a heat radiating member such as a heat radiating fin (heat sink).

  The heat dissipating fins constituting the heat dissipating member are generally made of a metal having a high thermal conductivity (that is, a heavy weight). However, when AFS is adopted, the weight is caused by the heat dissipating fins. In order to smoothly rotate the enlarged lamp unit, it is necessary to consider the setting of the center of gravity position. The setting of the position of the center of gravity needs to be considered in conjunction with avoiding the increase in the size of the vehicle headlamp described above, while ensuring the heat dissipation that is a function of the radiation fin.

  Although Patent Documents 1 and 2 disclose that a lamp unit having a plurality of LED light sources is integrally rotated or tilted, the rotation center and rotation in consideration of avoiding an increase in the size of a vehicle headlamp. There is no disclosure regarding the setting of the trajectory and the setting of the center of gravity in consideration of smoothly rotating the lamp unit.

  The present invention is a vehicle capable of smoothly rotating the lamp unit in the AFS while avoiding an increase in size due to prevention of interference with the headlight constituent member and optimizing the heat dissipation of the lamp unit. The purpose of this is to provide a headlight.

  The vehicle headlamp according to the present invention includes a lamp unit housed in a space formed by a housing and a translucent cover that covers an opening on the front surface of the housing, and is mounted on the vehicle front surface. In addition, the lamp unit includes a first LED lamp unit and a second LED lamp unit located outside the first LED lamp unit in the vehicle width direction. The LED lamp unit is provided with a lamp rotation drive unit that integrally rotates around a rotation axis extending in the substantially vertical direction from the initial position toward the outside in the vehicle width direction according to the vehicle running state, The LED lamp unit is configured to irradiate the light of the first LED light source upward from below to the reflector inclined forward and upward, and downward from the first LED light source. The second LED lamp unit has a metal second heat dissipating member that extends from the second LED light source to the rear of the vehicle, and has the first LED. A headlamp constituent member is provided on the inner side in the vehicle width direction of the lamp unit, and the rotation shaft is located at an end position of the first and second LED lamp units on the headlamp constituent member side. Is also arranged behind the vehicle.

  According to this configuration, it is possible to smoothly rotate the lamp unit in the AFS while optimizing the heat dissipation of the lamp unit while avoiding an increase in size due to prevention of interference with the headlight component. The vehicle headlamp which can be provided can be provided.

  Specifically, by extending the first heat radiating member below the first LED light source and extending the second heat radiating member behind the second LED light source, the first heat radiating member and the second heat radiating member are respectively It extends in the direction opposite to the irradiation direction of 1 LED light source and 2nd LED light source. Thereby, the heat emitted from the first and second LED light sources can be efficiently radiated from the back side (opposite the side irradiated with the light), and the heat dissipation performance for the first and second LED light sources can be optimized. Can do.

  Then, by disposing the pivot shaft at the rear of the vehicle from the end position on the headlamp component side, the end position is changed from the initial position to the headlight when the first and second LED lamp units are rotated. It can be displaced toward the vehicle width direction outer side opposite to the lamp component. In other words, the first and second LED lamp units can be rotated outward in the vehicle width direction while avoiding interference with the headlight component members, even if the headlight component members are not arranged at positions far away from the lamp unit. A turning trajectory that can be moved can be set.

  Accordingly, the first and second LED lamp units can be rotated outward in the vehicle width direction without causing an increase in the size of the lamp housing, and as a result, an increase in the size of the entire vehicle headlamp is avoided. be able to.

  Further, as described above, by extending the metal second heat radiating member behind the second LED light source, the center of gravity position of the assembly in which the first and second LED lamp units are integrated is closer to the rear of the vehicle. Although it is set, an effect that it can be brought close to the position of the center of gravity can be obtained by arranging the rotation shaft at the rear of the vehicle. In this way, the rotation of the first and second LED lamp units in the AFS can be made smooth by bringing the rotation shaft closer to the position of the center of gravity.

  In one embodiment of the present invention, the headlamp component is a decorative member.

  According to this configuration, the design of the vehicle headlamp can be enhanced by the decorative member while avoiding an increase in the size of the entire vehicle headlamp.

On the other hand, the second LED lamp unit has an inner lens that condenses the light of the second LED light source, condenses the light of the second LED light source with the lens, and forwards the vehicle from the translucent cover. It is configured to fire.

  According to this configuration, since the inner lens is provided only in the second LED lamp unit, when the first and second LED lamp units are arranged on both sides in the vehicle width direction of the vehicle front portion, One inner lens is arranged on each side in the vehicle width direction. For this reason, when the vehicle is viewed from the front, the inner lens can be used to make a design reminiscent of the eyes of a person or an animal, and the role as a design part of a vehicle headlamp can be effectively exhibited. be able to.

  On the other hand, the reflector of the first LED lamp unit only reflects the vicinity of the first LED light source below it, and the presence of the first LED lamp unit is not noticeable when the first LED light source does not emit light such as during the daytime. Become. Therefore, the degree of freedom in designing the vehicle headlamp can be improved by the amount that the presence of the first LED lamp unit is not noticeable.

  In one embodiment of the present invention, a black member that is reflected on the reflector when the first LED light source is not emitting light is provided.

  According to this configuration, when the first LED light source is not emitting light, the black member is reflected on the reflector, thereby making the first LED lamp unit less noticeable. Thereby, the design freedom of the vehicle headlamp can be further improved.

  In one embodiment of the present invention, the black member is a cover member that covers the first heat radiating member from above.

  According to this configuration, by covering the first heat radiating member with the cover member, it is possible to improve the appearance when the vehicle is viewed from the front. And the effect of improving the design freedom of a vehicle headlamp more using a cover member can also be acquired simultaneously.

  According to the present invention, it is possible to smoothly rotate the lamp unit in the AFS while optimizing the heat dissipation of the lamp unit while avoiding an increase in size due to the prevention of interference with the headlight component. The vehicle headlamp which can be provided can be provided.

Thereby, the heat generated from the first and second LED light sources 71 and 81 can be efficiently radiated from the back side (opposite the side irradiated with light), and the heat radiated to the first and second LED light sources 71 and 81. Sex can be optimized.

  Then, the rotation shafts 15a and 15b are disposed behind the end position P on the decorative member 10 side so that the end position P is set to the initial position when the first and second LED lamp units 7 and 8 are rotated. It can be displaced from the position toward the outside in the vehicle width direction opposite to the decorative member 10. That is, the first and second LED lamps can be avoided while avoiding interference with the decorative member 10 as shown by a two-dot chain line in FIG. 7 without arranging the decorative member 10 at a position far away from the first LED lamp unit 7. A rotation trajectory TR that can rotate the units 7 and 8 outward in the vehicle width direction can be set.
