Description

本発明は、車両用前照灯に関するものである。   The present invention relates to a vehicle headlamp.

車両用前照灯において、自車の視認性を向上させることと先行車や対向車（以下、併せて前方車両とも称する）の運転者にグレアを与えないこととを両立させるために、カットオフラインより上方の照射領域全域を照射するハイビーム用の配光パターンと、前方車両に対応する領域が遮光された部分遮蔽ハイビーム用の配光パターンとを切り替え可能な車両用前照灯が知られている（特許文献１参照）。   In vehicle headlamps, a cut-off line is used to improve the visibility of the vehicle and to prevent glare from being given to the driver of the preceding vehicle or oncoming vehicle (hereinafter also referred to as the forward vehicle). There is known a vehicle headlamp capable of switching between a light distribution pattern for a high beam that irradiates the entire upper irradiation region and a light distribution pattern for a partially shielded high beam in which a region corresponding to a preceding vehicle is shielded. (See Patent Document 1).

しかしながら、本発明者が様々な道路環境で視認性試験を行った結果、街路灯が少なく車両前方の周囲全体が暗い環境において、ハイビームの左側部分が遮蔽された右側ハイビーム配光パターンと、ハイビームの右側部分が遮蔽された左側ハイビーム配光パターンと、遮蔽された領域を持たない通常のハイビーム配光パターンと切り替えた場合、ハイビームの照射領域の上方付近に運転者が違和感を受けることがあった。   However, as a result of the inventor's visibility test in various road environments, in the environment where there are few street lights and the entire surrounding area in front of the vehicle is dark, When switching between the left-side high-beam light distribution pattern with the right-side portion shielded and the normal high-beam light-distribution pattern without the shielded region, the driver may feel uncomfortable near the upper portion of the high-beam irradiation region.

本発明の目的は、ハイビームの配光パターンを切り替えた際に運転者が感じる違和感を軽減することが可能な車両用前照灯を提供することにある。   An object of the present invention is to provide a vehicular headlamp that can reduce a sense of incongruity felt by a driver when a light distribution pattern of a high beam is switched.

上記課題を解決することのできる本発明の車両用前照灯は、光源と、前記光源の前方に配置され、前記光源からの光を前方に投影する投影レンズと、前記投影レンズの後方焦点の近傍に配置され、前記光源からの光が部分的に遮蔽された右側ハイビーム配光パターンと左側ハイビーム配光パターンの少なくとも一方と、前記光源からの光を遮蔽しない通常ハイビーム配光パターンとロービーム配光パターンの少なくとも一方とを切り替え可能な第１の遮蔽部材と、前記投影レンズの後方焦点から前方または後方に所定位置だけ離れた位置に配置され、ハイビームの上方領域を照射する光を遮蔽する第２の遮蔽部材と、を備えるものである。   A vehicle headlamp according to the present invention that can solve the above-described problems is a light source, a projection lens that is disposed in front of the light source and projects light from the light source forward, and a rear focal point of the projection lens. At least one of a right-side high-beam distribution pattern and a left-side high-beam distribution pattern that are arranged in the vicinity and partially shields light from the light source, and a normal high-beam distribution pattern and low-beam distribution that do not block light from the light source A first shielding member capable of switching at least one of the patterns, and a second shielding member arranged at a position away from the rear focal point of the projection lens by a predetermined position forward or backward, and shielding light that irradiates an upper region of the high beam. And a shielding member.

また、本発明の車両用前照灯は、前記第１の遮蔽部材を保持するベースプレートを備え、前記第２の遮蔽部材は、前記ベースプレートに固定されていることが好ましい。   Moreover, the vehicle headlamp according to the present invention preferably includes a base plate that holds the first shielding member, and the second shielding member is fixed to the base plate.

また、本発明の車両用前照灯は、前記投影レンズを保持するレンズホルダを備え、前記第２の遮蔽部材は、前記レンズホルダに固定されていることが好ましい。   The vehicle headlamp of the present invention preferably includes a lens holder that holds the projection lens, and the second shielding member is fixed to the lens holder.

また、本発明の車両用前照灯は、前記第２の遮蔽部材は、金属部材で構成され、撓められた状態で前記レンズホルダに取り付けられていることが好ましい。   In the vehicle headlamp of the present invention, it is preferable that the second shielding member is made of a metal member and attached to the lens holder in a bent state.

本発明の車両用前照明灯によれば、第２の遮蔽部材によって、ハイビームの上方領域を照射する光がカットされる。また、投影レンズの後方焦点から前方または後方に所定距離だけ離れた位置に第２の遮蔽部材が配置されているため、ハイビームの上方領域において、照射領域と非照射領域との境界がぼやけた状態となる。従って、ハイビームの各配光パターンを切り替えた際に運転者がハイビームの上方領域に対して感じていた違和感が軽減される。   According to the vehicle front illumination lamp of the present invention, the light that irradiates the upper region of the high beam is cut by the second shielding member. In addition, since the second shielding member is disposed at a predetermined distance away from the rear focal point of the projection lens forward or backward, the boundary between the irradiation region and the non-irradiation region is blurred in the upper region of the high beam. It becomes. Therefore, the uncomfortable feeling that the driver felt for the upper region of the high beam when switching each light distribution pattern of the high beam is reduced.

第２のシェードユニット５０は、図３に示すように、金属製の長細い薄板をプレスなどで屈曲させることにより一体的に形成されており、光源１１からの光の一部を遮光する遮蔽板部（第２の遮蔽部材の一例）５１と、取付部５２と、遮蔽板部５１と取付部５２とを連結する連結部５３と、を有する。遮蔽板部５１は、矩形板状に形成され、光軸Ａｘに対して垂直になるように設けられている。取付部５２は矩形状に形成され、その面が灯具内で水平方向に沿うように設けられている。また、取付部５２の略中央部には３箇所の貫通孔５２Ａが設けられている。連結部５３は中間部が屈曲されて側面視略Ｌ字状に形成され、その両先端部で遮蔽板部５１と取付部５２とに接続している。   As shown in FIG. 3, the second shade unit 50 is integrally formed by bending a metal thin thin plate with a press or the like, and shields a part of light from the light source 11. Part (an example of a second shielding member) 51, an attachment part 52, and a connecting part 53 that connects the shielding plate part 51 and the attachment part 52. The shielding plate part 51 is formed in a rectangular plate shape and is provided so as to be perpendicular to the optical axis Ax. The attachment portion 52 is formed in a rectangular shape, and the surface thereof is provided in the lamp in the horizontal direction. In addition, three through holes 52 </ b> A are provided at a substantially central portion of the attachment portion 52. The connecting portion 53 is formed in a substantially L shape when viewed from the side by bending an intermediate portion, and is connected to the shielding plate portion 51 and the mounting portion 52 at both ends.

第２のシェードユニット５０は、図１に示すように、取付部５２の貫通孔５２Ａにボルト５２Ｂが挿通しナットで締められることにより、フレーム４１の支持プレート４８に固定される。このため、第２のシェードユニット５０の遮蔽板部５１は投影レンズ３０の後方焦点Ｆ２から灯具前方に所定位置だけ離れた位置に固定支持される。この第２のシェードユニット５０の遮蔽板部５１は、投影レンズ３０の後方焦点Ｆ２から外れた位置で、灯具内で光源１１からの光のうち下方領域を遮蔽するため、結果的に、例えば鉛直仮想スクリーンにおいてハイビームの上方領域を照射する光を遮蔽することになる。   As shown in FIG. 1, the second shade unit 50 is fixed to the support plate 48 of the frame 41 by inserting a bolt 52 </ b> B into the through hole 52 </ b> A of the attachment portion 52 and fastening with a nut. For this reason, the shielding plate 51 of the second shade unit 50 is fixedly supported at a position away from the rear focal point F2 of the projection lens 30 by a predetermined position in front of the lamp. The shielding plate portion 51 of the second shade unit 50 shields the lower region of the light from the light source 11 in the lamp at a position deviated from the rear focal point F2 of the projection lens 30. The light that irradiates the area above the high beam on the virtual screen is shielded.

次に、図４を参照しながら、本実施形態の車両用灯具１Ａにより照射可能な配光パターンについて説明する。
なお、図４は、車両用灯具１Ａの前方２５ｍの位置に配置される仮想鉛直スクリーン上に投影される配光パターンを示している。仮想鉛直スクリーンは、光軸が通る点を原点Ｏと水平方向を規定するＨ軸（横軸）と垂直方向を規定するＶ軸（縦軸）とで規定したものである。 Next, a light distribution pattern that can be irradiated by the vehicle lamp 1A of the present embodiment will be described with reference to FIG.
FIG. 4 shows a light distribution pattern projected on a virtual vertical screen arranged at a position 25 m ahead of the vehicular lamp 1A. In the virtual vertical screen, the point through which the optical axis passes is defined by the origin O, the H axis (horizontal axis) that defines the horizontal direction, and the V axis (vertical axis) that defines the vertical direction.

本実施形態の車両用灯具１Ａは、図４（ａ）〜（ｄ）に示す４つの配光パターンを形成することができる。
図４（ａ）は、通常のロービーム配光パターンＬｏＣを示している。この配光パターンＬｏＣでは、市街地走行時などに前方車両や歩行者にグレアを与えることはない。この配光パターンＬｏＣは、車両用灯具１Ａの第１のシェードユニット４０が、所定の制御ユニットによりロービーム照射モードに設定されことにより得られる。即ち、第１のシェードユニット４０において、ロービーム用の遮蔽板部４３ａが遮光姿勢（図２に図示される水平状態の姿勢）となり、部分ハイビーム用の遮蔽板部４３ｂが退避姿勢（図２に図示される水平から下方に少し回転した姿勢）となり、その結果、ロービーム用の遮蔽板部４３ａがフレーム４１の第１の貫通孔４４の下側部の一部に重なり、その部分で光源１１からの光が遮光されることにより、配光パターンＬｏＣが得られる。 The vehicular lamp 1A according to the present embodiment can form four light distribution patterns shown in FIGS.
FIG. 4A shows a normal low beam light distribution pattern LoC. With this light distribution pattern LoC, glare is not given to the preceding vehicle or pedestrian when traveling in an urban area. The light distribution pattern LoC is obtained by setting the first shade unit 40 of the vehicle lamp 1A to the low beam irradiation mode by a predetermined control unit. That is, in the first shade unit 40, the low-beam shielding plate portion 43a is in the light-shielding posture (horizontal posture shown in FIG. 2), and the partial high-beam shielding plate portion 43b is in the retracted posture (shown in FIG. 2). As a result, the low-beam shielding plate portion 43a overlaps a part of the lower side portion of the first through hole 44 of the frame 41, and the portion from the light source 11 The light distribution pattern LoC is obtained by blocking the light.

図４（ｂ）は、通常のハイビーム配光パターンＨｉＣを示している。この配光パターンＨｉＣは、運転者の前方視界を最大まで確保できる配光パターンである。この配光パターンＨｉＣは、車両用灯具１Ａの第１のシェードユニット４０が、所定の制御ユニットによりハイビーム照射モードに設定されることにより得られる。即ち、第１のシェードユニット４０において、ロービーム用の遮蔽板部４３ａと部分ハイビーム用の遮蔽板部４３ｂとが共に退避姿勢となり、フレーム４１の第１の貫通孔４４に重ならず、これらの遮蔽板部４３ａ，４３ｂにより光源からの光が遮光されない。一方で、第１の貫通孔４４を通過した光は第２のシェードユニット５０の遮蔽板部５１によりその一部が遮光される。このとき、第２のシェードユニット５０の遮蔽板部５１は投影レンズ３０の後方焦点Ｆ２から灯具前方に外れているため、照射領域と非照射領域との境界がぼやけた状態でハイビームの上方領域ＦＡが遮蔽されることになる。   FIG. 4B shows a normal high beam light distribution pattern HiC. This light distribution pattern HiC is a light distribution pattern that can ensure the driver's front view to the maximum. This light distribution pattern HiC is obtained by setting the first shade unit 40 of the vehicular lamp 1A to the high beam irradiation mode by a predetermined control unit. That is, in the first shade unit 40, both the low beam shielding plate portion 43a and the partial high beam shielding plate portion 43b are in the retracted posture and do not overlap the first through hole 44 of the frame 41. The light from the light source is not blocked by the plate portions 43a and 43b. On the other hand, a part of the light that has passed through the first through hole 44 is shielded by the shielding plate portion 51 of the second shade unit 50. At this time, since the shielding plate portion 51 of the second shade unit 50 is out of the lamp front from the rear focal point F2 of the projection lens 30, the upper area FA of the high beam in a state where the boundary between the irradiation area and the non-irradiation area is blurred. Will be shielded.

図４（ｃ）は左側ハイビーム配光パターンＨｉＣＬを示し、図４（ｄ）は右側ハイビーム配光パターンＨｉＣＲを示している。この配光パターンＨｉＣＬは、Ｈ-Ｖ領域のうち右上側領域以外が照射されており、自車線側に先行車や歩行者が存在せず、対向車側に対向車や歩行者が存在する場合に適した配光パターンであり、運転者の前方視認性を確保しつつ、対向車や対向車線の歩行者にグレアを与えないようにしたものである。   FIG. 4C shows the left high beam light distribution pattern HiCL, and FIG. 4D shows the right high beam light distribution pattern HiCR. This light distribution pattern HiCL is irradiated in areas other than the upper right side of the HV area, and there is no preceding vehicle or pedestrian on the own lane side, and there is an oncoming vehicle or pedestrian on the oncoming vehicle side. The light distribution pattern is suitable for the vehicle, and the glare is not given to the oncoming vehicle or the pedestrian in the oncoming lane while ensuring the driver's forward visibility.

一方で、この配光パターンＨｉＣＲは、Ｈ-Ｖ領域のうち左上側領域以外が照射されており、自車線側に先行車や歩行者が存在し、対向車線側に対向車や歩行者が存在しない場合に適した配光パターンであり、配光パターンＨｉＣＬと同様に、運転者の前方視認性を確保しつつ、対向車や対向車線の歩行者にグレアを与えないようにしたものである。   On the other hand, this light distribution pattern HiCR is irradiated in areas other than the upper left area in the HV area, the preceding vehicle and the pedestrian exist on the own lane side, and the oncoming vehicle and the pedestrian exist on the opposite lane side. This is a light distribution pattern suitable for the case where the vehicle does not perform, and, like the light distribution pattern HiCL, glare is not given to the oncoming vehicle or the pedestrian in the oncoming lane while ensuring the driver's forward visibility.

これら配光パターンＨｉＣＬ，ＨｉＣＲは、車両用灯具１Ａの第１のシェードユニット４０が所定の制御ユニットにより、右側または左側ハイビーム照射モードに設定されことにより得られる。即ち、第１のシェードユニット４０において、一対の遮蔽板部４３ａ，４３ｂのうち部分ハイビーム用の遮蔽板部４３ｂのみが遮蔽姿勢となり、フレーム４１の第１の貫通孔４４の下側部のうち左右一方で重なり、その部分で光源からの光が遮光されることにより得られる。ここで、第１のシェードユニット４０の遮蔽板部４３により遮光されず、第１の貫通孔４４を通過した光は第２のシェードユニット５０の遮蔽板部５１により上方領域に向かう光の一部が遮光される。このとき、第２のシェードユニット５０の遮蔽板部５１は投影レンズ３０の後方焦点Ｆ２から灯具前方向に外れた位置に配置されている。このため、照射領域と非照射領域との境界がぼやけた状態でハイビームの上方左領域ＦＬ（図４（ｃ）参照）又は上方右領域ＦＲ（図４（ｄ）参照）が遮蔽される。
なお、以上説明した車両用灯具１Ａは、車両の車幅方向の左右に配置されるものであり、その構造は実質的に左右同等である。車両用灯具１Ａが車幅方向の左側に配置されるものである場合は、左側配光パターンＨｉＣＬを形成できるように遮蔽部材４３ａ，４３ｂの形状を設計し、車両用灯具１Ａが車幅方向の右側に配置されるものである場合は、右側配光パターンＨｉＣＲを形成できるように遮蔽部材４３ａ，４３ｂの形状を設計すれば良い。 These light distribution patterns HiCL and HiCR are obtained by setting the first shade unit 40 of the vehicular lamp 1A to the right or left high beam irradiation mode by a predetermined control unit. That is, in the first shade unit 40, only the partial high beam shielding plate 43b of the pair of shielding plates 43a and 43b is in the shielding posture, and left and right of the lower side portion of the first through hole 44 of the frame 41 On the other hand, they are overlapped, and the light from the light source is shielded at that portion. Here, a part of the light that is not shielded by the shielding plate portion 43 of the first shade unit 40 and that has passed through the first through hole 44 is directed upward by the shielding plate portion 51 of the second shade unit 50. Is shielded from light. At this time, the shielding plate portion 51 of the second shade unit 50 is disposed at a position deviated from the rear focal point F2 of the projection lens 30 in the forward direction of the lamp. For this reason, the upper left region FL (see FIG. 4C) or the upper right region FR (see FIG. 4D) of the high beam is blocked while the boundary between the irradiated region and the non-irradiated region is blurred.
The vehicular lamp 1A described above is arranged on the left and right in the vehicle width direction of the vehicle, and the structure thereof is substantially the same on the left and right. When the vehicular lamp 1A is arranged on the left side in the vehicle width direction, the shapes of the shielding members 43a and 43b are designed so that the left light distribution pattern HiCL can be formed, and the vehicular lamp 1A is arranged in the vehicle width direction. In the case of being arranged on the right side, the shape of the shielding members 43a and 43b may be designed so that the right side light distribution pattern HiCR can be formed.

以上のように、本実施形態の車両用灯具１Ａによれば、第２のシェードユニット５０によって、通常のハイビーム配光パターンＨｉＣや左側ハイビーム配光パターンＨｉＣＬや右側ハイビーム配光パターンＨｉＣＲのハイビームの上方領域を照射する光がカットされる。また、投影レンズ３０の後方焦点Ｆ２から前方に所定距離だけ離れた位置に第２のシェードユニット５０の遮蔽板部５１が配置されているため、照射領域と非照射領域との境界がぼやけた状態となる。したがって、ハイビームの各配光パターンを切り替えた際に運転者がハイビームの上方付近に対して感じていた違和感が軽減される。   As described above, according to the vehicular lamp 1A of the present embodiment, the second shade unit 50 causes the high beam of the normal high beam light distribution pattern HiC, the left high beam light distribution pattern HiCL, and the right high beam light distribution pattern HiCR to be above. The light that illuminates the area is cut. In addition, since the shielding plate portion 51 of the second shade unit 50 is disposed at a predetermined distance forward from the rear focal point F2 of the projection lens 30, the boundary between the irradiation region and the non-irradiation region is blurred. It becomes. Therefore, the uncomfortable feeling that the driver feels in the vicinity of the upper part of the high beam when switching each light distribution pattern of the high beam is reduced.
