　図１は、実施の形態に係る車両用灯具１０の概略正面図である。図２は、図１に示される車両用灯具１０のＡ－Ａ線による水平断面を示す概略図である。 FIG. 1 is a schematic front view of a vehicle lamp 10 according to the embodiment. FIG. 2 is a schematic view showing a horizontal cross section taken along line AA of the vehicle lamp 10 shown in FIG.
　車両用灯具１０は、車両前方の左右に配置される一対の前照灯ユニットを有する車両用前照灯装置である。一対の前照灯ユニットは概ね左右対称の構造を有し、実質的に同一の構成であるため、図１および図２には車体前方から見て左側に位置する車両用灯具を示す。よって、図１および図２において左側が車幅方向外側にあたり、右側が車幅方向内側にあたる。 The vehicle lamp 10 is a vehicle headlamp device having a pair of headlamp units arranged on the left and right in front of the vehicle. Since the pair of headlight units have a substantially symmetrical structure and substantially the same configuration, FIGS. 1 and 2 show a vehicular lamp located on the left side when viewed from the front of the vehicle body. Therefore, in FIGS. 1 and 2, the left side corresponds to the outside in the vehicle width direction, and the right side corresponds to the inside in the vehicle width direction.
　車両用灯具１０は、前面開口１３を有する灯具ボディ１２と、前面開口１３を覆うように灯具ボディ１２に取り付けられた前面カバー１４と、を備える。灯具ボディ１２は、車体に取付可能に構成され、前面カバー１４は、灯具ボディ１２を介して車体に取り付けられる。灯具ボディ１２と前面カバー１４とによって灯具筐体が構成され、灯具筐体の内部空間が灯室１６として形成されている。灯具ボディ１２は、例えば、樹脂材料で形成されている。前面開口１３は、車両前方側に開口している。前面カバー１４は、透光性を有する樹脂やガラス等で形成されている。 The vehicle lamp 10 includes a lamp body 12 having a front opening 13, and a front cover 14 attached to the lamp body 12 so as to cover the front opening 13. The lamp body 12 is configured to be attachable to the vehicle body, and the front cover 14 is attached to the vehicle body via the lamp body 12. A lamp housing is configured by the lamp body 12 and the front cover 14, and an internal space of the lamp housing is formed as a lamp chamber 16. The lamp body 12 is formed of, for example, a resin material. The front opening 13 is open toward the front of the vehicle. The front cover 14 is formed of a translucent resin, glass, or the like.
　車両用灯具１０は、可動灯具ユニット１８および固定灯具ユニット２０を備え、これらは灯室１６内に配置されている。一例として、可動灯具ユニット１８は、前照灯として機能し、固定灯具ユニット２０は、クリアランスランプ及び／またはデイライトランニングランプ、またはその他の標識灯として機能する。限定的ではない例として、可動灯具ユニット１８が車幅方向外側に配置され、固定灯具ユニット２０が車幅方向内側に配置されている。 The vehicle lamp 10 includes a movable lamp unit 18 and a fixed lamp unit 20, which are arranged in the lamp room 16. As an example, the movable lamp unit 18 functions as a headlight, and the fixed lamp unit 20 functions as a clearance lamp and / or a daylight running lamp, or other marker lamp. As a non-limiting example, the movable lamp unit 18 is arranged outside in the vehicle width direction, and the fixed lamp unit 20 is arranged inside in the vehicle width direction.

Specifically, for example, the movable lamp unit 18 is supported by the lamp body 12 so as to be tiltable with respect to the lamp body 12 for optical axis adjustment. The fixed lamp unit 20 is fixedly supported on the lamp body 12. Therefore, the fixed lamp unit 20 does not move with respect to the lamp body 12.
　また、車両用灯具１０は、図２に示されるように、灯具ボディ１２の前方に配置されたブラケット２２と、ブラケット２２に装着されたワイヤーハーネス２４と、を備える。可動灯具ユニット１８と固定灯具ユニット２０は、互いに隣接して、ブラケット２２の前方に配置されている。 As shown in FIG. 2, the vehicular lamp 10 includes a bracket 22 disposed in front of the lamp body 12 and a wire harness 24 mounted on the bracket 22. The movable lamp unit 18 and the fixed lamp unit 20 are arranged adjacent to each other and in front of the bracket 22.
　ブラケット２２は、前面カバー１４側を向く前面２２ａと、灯具ボディ１２側を向く背面２２ｂとを有する。ブラケット２２の一部分（例えば、車幅方向外側の半分）が可動灯具ユニット１８の後方に位置し、ブラケット２２の他の一部分（例えば、車幅方向内側の半分）が固定灯具ユニット２０の後方に位置する。ブラケット２２の背面２２ｂは、灯具ボディ１２の背部と向かい合っている。ブラケット２２は、例えば樹脂材料で形成されている。ブラケット２２は、配線支持ブラケットまたはボディ側ブラケットと呼ぶこともできる。 The bracket 22 has a front surface 22a facing the front cover 14 and a rear surface 22b facing the lamp body 12. A part of the bracket 22 (for example, the outer half in the vehicle width direction) is located behind the movable lamp unit 18, and another part (for example, an inner half in the vehicle width direction) is located behind the fixed lamp unit 20. I do. The back surface 22 b of the bracket 22 faces the back of the lamp body 12. The bracket 22 is formed of, for example, a resin material. The bracket 22 can also be called a wiring support bracket or a body side bracket.
　ブラケット２２は、灯室１６を後方スペース４０と前方スペース４２に仕切る仕切板とも言える。後方スペース４０は、ブラケット２２と灯具ボディ１２との間の領域にあたる。後方スペース４０には、ワイヤーハーネス２４の大半の部分が収容されうる。前方スペース４２は、ブラケット２２と前面カバー１４との間の領域にあたり、可動灯具ユニット１８および固定灯具ユニット２０が配置される。 The bracket 22 can also be said to be a partition plate that partitions the lamp room 16 into a rear space 40 and a front space 42. The rear space 40 corresponds to a region between the bracket 22 and the lamp body 12. The rear space 40 can accommodate most of the wire harness 24. The front space 42 corresponds to a region between the bracket 22 and the front cover 14, and the movable lamp unit 18 and the fixed lamp unit 20 are arranged.
　詳細は後述するが、ワイヤーハーネス２４は、可動灯具ユニット１８の後方でブラケット２２の背面２２ｂに設けられ、固定灯具ユニット２０の後方でブラケット２２の背面２２ｂから前面２２ａへと延びている。ブラケット２２は、固定灯具ユニット２０の後方に位置する開口部２３を有する。ワイヤーハーネス２４は、ブラケット２２の背面２２ｂに配策され、開口部２３を通じてブラケット２２の背面２２ｂから前面２２ａへと案内されている。なお以下では、他のワイヤーハーネスと区別するために、ワイヤーハーネス２４を第１ワイヤーハーネス２４と称することがある。 As will be described later in detail, the wire harness 24 is provided on the rear surface 22 b of the bracket 22 behind the movable lamp unit 18, and extends from the rear surface 22 b of the bracket 22 to the front surface 22 a behind the fixed lamp unit 20.

The details of the current plate 32 will be described later.
　図３および図４は、実施の形態に係るブラケット２２を示す概略斜視図である。図３には、ブラケット２２の前面２２ａが示され、図４には、ブラケット２２の背面２２ｂが示されている。 FIGS. 3 and 4 are schematic perspective views showing the bracket 22 according to the embodiment. 3 shows a front surface 22a of the bracket 22, and FIG. 4 shows a rear surface 22b of the bracket 22.

　図３および図４には、ブラケット２２とともに第１ワイヤーハーネス２４が示されている。第１ワイヤーハーネス２４は、複数のコネクタ２４ａ～２４ｇを有する。第１ワイヤーハーネス２４は、第１コネクタ２４ａから延び、途中で複数本のコードへと分岐し、各コードの末端に残りのコネクタ２４ｂ～２４ｇが設けられている。 FIGS. 3 and 4 show the first wire harness 24 together with the bracket 22.

The first wire harness 24 extends from the first connector 24a, branches into a plurality of cords along the way, and the remaining connectors 24b to 24g are provided at the ends of each cord.
　第１コネクタ２４ａ、第２コネクタ２４ｂ、第３コネクタ２４ｃは、ブラケット２２の前面２２ａ側に配置されている。第１コネクタ２４ａは、上述のように、第２ワイヤーハーネス２６に接続される。第２コネクタ２４ｂは、第１ワイヤーハーネス２４を可動灯具ユニット１８に接続するために設けられている。第３コネクタ２４ｃは、第１ワイヤーハーネス２４を固定灯具ユニット２０に接続するために設けられている。 The first connector 24a, the second connector 24b, and the third connector 24c are arranged on the front surface 22a side of the bracket 22.

　第１ワイヤーハーネス２４は、互いに間隔を空けてコードに沿って設けられた複数のコードクランプ４４を有し、これらコードクランプ４４は、ブラケット２２の背面２２ｂ側に固定されている。 The first wire harness 24 has a plurality of cord clamps 44 provided along the cords at intervals from each other, and these cord clamps 44 are fixed to the back surface 22 b side of the bracket 22.
　図５（ａ）から図５（ｃ）は、実施の形態に係るコネクタ保持構造２８を説明するための概略図である。コネクタ保持構造２８は、ブラケット２２の表面（例えば、前面２２ａまたは背面２２ｂ）に形成された凸部または凹部を含む。コネクタ保持構造２８は、互いに接続される２つのコネクタが正規に嵌合しているとき、それらコネクタを所定位置に保持するように形状が定められている。コネクタ保持構造２８は、それら２つのコネクタの接続が不完全であるとき（いわゆる半嵌合であるとき）、所定位置から外れて位置するように構成されている。言い換えれば、２つのコネクタの接続が不完全であるとき、それらコネクタの結合体がコネクタ保持構造２８に収まらないように、コネクタ保持構造２８の形状および寸法が定められている。 FIGS. 5A to 5C are schematic diagrams for explaining the connector holding structure 28 according to the embodiment. The connector holding structure 28 includes a convex portion or a concave portion formed on the surface (for example, the front surface 22a or the rear surface 22b) of the bracket 22. The connector holding structure 28 is shaped such that when two connectors to be connected to each other are properly fitted, the connectors are held at predetermined positions. The connector holding structure 28 is configured to be located out of a predetermined position when the connection between the two connectors is incomplete (so-called half-fitting). In other words, the shape and dimensions of the connector holding structure 28 are determined so that when the connection between the two connectors is incomplete, the combined body of the connectors does not fit in the connector holding structure 28.
　図５（ａ）には、２つのコネクタ（例えば、第１ワイヤーハーネス２４の第１コネクタ２４ａと第２ワイヤーハーネス２６の相手コネクタ２６ａ）が正規に嵌合し、従って、第１ワイヤーハーネス２４と第２ワイヤーハーネス２６が完全に接続された状態が示されている。２つのコネクタは、いずれか一方がオス型コネクタであり、他方がメス型コネクタである。一方のコネクタ、例えば第１コネクタ２４ａが、装着部４６を有し、装着部４６を介してブラケット２２に固定されている。装着部４６は、基準位置４８を定める。２つのコネクタの接続作業を容易にするために、装着部４６は、固定されたコネクタがブラケット２２に対して多少の動きを可能とするように構成されている。 In FIG. 5A, two connectors (for example, the first connector 24a of the first wire harness 24 and the mating connector 26a of the second wire harness 26) are properly fitted. The state where the second wire harness 26 is completely connected is shown. One of the two connectors is a male connector, and the other is a female connector. One connector, for example, the first connector 24 a has a mounting portion 46 and is fixed to the bracket 22 via the mounting portion 46. The mounting section 46 defines a reference position 48. To facilitate the work of connecting the two connectors, the mounting portion 46 is configured such that the fixed connector allows some movement with respect to the bracket 22.
　図５（ａ）に示されるように、コネクタ保持構造２８は、ブラケット２２の表面に形成されたコネクタ保持凸部５０を有する。距離Ｐは、基準位置４８からコネクタ保持凸部５０までの距離を表し、距離Ｑは、２つのコネクタが正規に嵌合したときの基準位置４８から相手コネクタ２６ａの端面５２までの距離を表す。ここでは、端面５２からコードが延びている。コネクタ保持構造２８は、距離Ｐが距離Ｑと等しくなるように設計されている。すなわち、コネクタ保持凸部５０は、距離Ｐが距離Ｑと等しくなるようにブラケット２２の表面に形成されている。したがって、２つのコネクタが正規に嵌合したとき、これらコネクタは、コネクタ保持構造２８にちょうど収まっている。 5A, the connector holding structure 28 has a connector holding projection 50 formed on the surface of the bracket 22. The distance P represents the distance from the reference position 48 to the connector holding projection 50, and the distance Q represents the distance from the reference position 48 to the end face 52 of the mating connector 26a when the two connectors are properly fitted. Here, the cord extends from the end face 52. The connector holding structure 28 is designed such that the distance P is equal to the distance Q. That is, the connector holding projection 50 is formed on the surface of the bracket 22 such that the distance P is equal to the distance Q. Thus, when the two connectors are properly mated, they are just seated in the connector holding structure 28.
　ところが、図５（ｂ）に示されるように、２つのコネクタがしっかりと接続されていない場合には、基準位置４８から相手コネクタ２６ａの端面５２までの距離Ｒは、当然、距離Ｑより長くなる。よって、距離Ｒは、距離Ｐより長い。そうすると、２つのコネクタの結合体は、コネクタ保持凸部５０に妨げられて、コネクタ保持構造２８に収まらない。このように半嵌合となっている２つのコネクタはコネクタ保持構造２８から外れてしまう。作業者は、コネクタの半嵌合を目視により容易に確認することができる。その場合、作業者は、コネクタを接続し直して、正規に嵌合することができる。 However, as shown in FIG. 5B, when the two connectors are not securely connected, the distance R from the reference position 48 to the end surface 52 of the mating connector 26a is naturally longer than the distance Q. . Therefore, the distance R is longer than the distance P. Then, the combined body of the two connectors is blocked by the connector holding projection 50 and does not fit in the connector holding structure 28. The two connectors that are half-fitted in this way come off the connector holding structure 28. An operator can easily confirm the half-fitting of the connector visually. In that case, the worker can reconnect the connector and fit properly.
　図５（ｃ）に示されるように、コネクタ保持構造２８は、ブラケット２２の表面に形成されたコネクタ保持凹部５３を有してもよい。例えば、コネクタ保持凹部５３の一端を基準位置４８とすることができる。同様にして、基準位置４８からコネクタ保持凹部５３の他端までの距離Ｐが、正規に嵌合した２つのコネクタの長さに相当する距離Ｑと等しくなるように、コネクタ保持構造２８（すなわちコネクタ保持凹部５３の形状および寸法）が設計されてもよい。 コ ネ ク タ As shown in FIG. 5C, the connector holding structure 28 may have a connector holding recess 53 formed on the surface of the bracket 22. For example, one end of the connector holding recess 53 can be set as the reference position 48. Similarly, the connector holding structure 28 (that is, the connector holding structure 28) is set so that the distance P from the reference position 48 to the other end of the connector holding recess 53 is equal to the distance Q corresponding to the length of the two properly fitted connectors. The shape and dimensions of the holding recess 53 may be designed.
　こうしたコネクタ保持構造２８は、例示した特定の２つのコネクタには限定されず、任意の２つのコネクタのためにブラケット２２の前面２２ａ及び／または背面２２ｂに設けられてもよい。あるいは、必要とされる場合には、コネクタ保持構造２８は、車両用灯具１０内の任意の壁面、または任意の部材の表面に設けられてもよい。 The connector holding structure 28 is not limited to the specific two connectors illustrated, and may be provided on the front surface 22a and / or the rear surface 22b of the bracket 22 for any two connectors. Alternatively, if necessary, the connector holding structure 28 may be provided on any wall surface in the vehicle lamp 10 or on the surface of any member.
　図６は、図１に示される車両用灯具１０のＢ－Ｂ線による鉛直断面を示す概略図である。図６を参照して、整流板３２について、さらに説明する。 FIG. 6 is a schematic view showing a vertical cross section of the vehicle lamp 10 shown in FIG. 1 taken along line BB. Referring to FIG. 6, the current plate 32 will be further described.
　図６に示されるように、可動灯具ユニット１８は、複数のサブアセンブリ（１８ａ～１８ｃ）を備える。複数のサブアセンブリは相互に相対位置が固定されている。可動灯具ユニット１８は、限定しない例として、階段状に配置された３つのサブアセンブリを備え、以下ではこれらを、第１サブアセンブリ１８ａ、第２サブアセンブリ１８ｂ、第３サブアセンブリ１８ｃと表記することがある。すなわち、最も上方の第１サブアセンブリ１８ａが最も後方に配置され、最も下方の第３サブアセンブリ１８ｃが最も前方に配置されている。 可 動 As shown in FIG. 6, the movable lamp unit 18 includes a plurality of sub-assemblies (18a to 18c). The plurality of subassemblies have fixed relative positions to each other. The movable lamp unit 18 includes, as a non-limiting example, three sub-assemblies arranged in a stepped manner, and these are hereinafter referred to as a first sub-assembly 18a, a second sub-assembly 18b, and a third sub-assembly 18c. There is. That is, the uppermost first sub-assembly 18a is disposed at the rearmost position, and the lowermost third subassembly 18c is disposed at the frontmost position.
　各サブアセンブリは、放熱部５６を有する発光素子搭載部５４を備える。また、各サブアセンブリは、光源５８と、少なくとも１つの光学部材（例えば、リフレクタ６０、投影レンズ６２）とを備える。 Each subassembly includes a light emitting element mounting section 54 having a heat radiating section 56. Each subassembly includes a light source 58 and at least one optical member (for example, the reflector 60 and the projection lens 62).
　発光素子搭載部５４は、光源５８を支持する支持面を提供し、放熱部５６と一体形成されている。放熱部５６は、発光素子搭載部５４から後方に向けて延びる複数の放熱フィンを有する。各放熱フィンは鉛直面と平行であってもよい。発光素子搭載部５４および放熱部５６は、光源５８が発生する熱を放熱する放熱部材としても機能し、ヒートシンクとも呼ばれる。発光素子搭載部５４および放熱部５６は、例えばアルミニウムまたはアルミニウム合金などの高熱伝導率をもつ金属材料で形成され、例えばダイキャスト法により製造されている。また、発光素子搭載部５４は、リフレクタ６０および投影レンズ６２を支持するように構成されている。 The light emitting element mounting section 54 provides a support surface for supporting the light source 58 and is formed integrally with the heat radiating section 56. The heat radiating portion 56 has a plurality of heat radiating fins extending rearward from the light emitting element mounting portion 54. Each radiating fin may be parallel to the vertical plane. The light emitting element mounting portion 54 and the heat radiating portion 56 also function as a heat radiating member for radiating heat generated by the light source 58, and are also called a heat sink. The light emitting element mounting portion 54 and the heat radiating portion 56 are formed of a metal material having a high thermal conductivity such as aluminum or an aluminum alloy, and are manufactured by, for example, a die casting method. Further, the light emitting element mounting section 54 is configured to support the reflector 60 and the projection lens 62.
　光源５８は、例えば、発光ダイオード（ＬＥＤ）などの半導体発光素子５８ａと、半導体発光素子５８ａを支持する基板５８ｂとを有する。基板５８ｂは、セラミックなどで形成された熱伝導性絶縁基板である。基板５８ｂには、半導体発光素子５８ａに電力を伝達する電極（図示せず）が形成されている。光源５８は、半導体発光素子５８ａの光出射面が車両上方に向けられ、半導体発光素子５８ａの照射軸が略車両上下方向に延びた状態で、発光素子搭載部５４に搭載されている。 The light source 58 includes, for example, a semiconductor light emitting device 58a such as a light emitting diode (LED) and a substrate 58b supporting the semiconductor light emitting device 58a. The substrate 58b is a heat conductive insulating substrate formed of ceramic or the like. An electrode (not shown) for transmitting power to the semiconductor light emitting element 58a is formed on the substrate 58b. The light source 58 is mounted on the light emitting element mounting part 54 with the light emitting surface of the semiconductor light emitting element 58a directed upward of the vehicle and the irradiation axis of the semiconductor light emitting element 58a extending substantially in the vertical direction of the vehicle.
　リフレクタ６０は、光源５８の出射光を投影レンズ６２へと反射するように光源５８の上方に配置されている。リフレクタ６０は、光源５８に対向する内面に反射面が形成された反射部材であり、反射面は例えば回転楕円面の一部で構成されている。また、投影レンズ６２は、リフレクタ６０からの反射光を灯具前方に投影するように光源５８に対して前方に配置されている。投影レンズ６２は、一例として、前方側表面が凸面で後方側表面が平面の平凸非球面レンズであり、透明樹脂材料で形成されている。 The reflector 60 is disposed above the light source 58 so as to reflect the light emitted from the light source 58 to the projection lens 62. The reflector 60 is a reflection member having a reflection surface formed on an inner surface facing the light source 58, and the reflection surface is formed by, for example, a part of a spheroid. Further, the projection lens 62 is disposed forward of the light source 58 so as to project the reflected light from the reflector 60 forward of the lamp. As an example, the projection lens 62 is a plano-convex aspheric lens having a convex front surface and a flat rear surface, and is formed of a transparent resin material.
　なお、可動灯具ユニット１８は、上述の具体例には限られず、他の公知の構成を適宜採用することもできる。 The movable lamp unit 18 is not limited to the specific example described above, and other known configurations may be appropriately adopted.
　送風機３０は、上述のように、ブラケット２２に設置され、可動灯具ユニット１８の後方に配置されている。送風機３０は、ブラケット２２の前面２２ａに吹出口３０ａを有し、ブラケット２２の背面２２ｂに吸気口３０ｂを有する。よって、吸気口３０ｂは、後方スペース４０から吸気し、吹出口３０ａは、前方スペース４２へと空気を吹き出す。送風機３０は、例えば軸流ファンであり、ブラケット２２の送風機取付穴に取り付けられた薄型のファンであってもよい。送風機３０は、第３サブアセンブリ１８ｃとほぼ同じ高さに配置され、吹出口３０ａは、第３サブアセンブリ１８ｃの後方に位置する。 The blower 30 is installed on the bracket 22 and is arranged behind the movable lamp unit 18 as described above. The blower 30 has an air outlet 30 a on the front surface 22 a of the bracket 22 and an air inlet 30 b on the rear surface 22 b of the bracket 22. Therefore, the air inlet 30b draws air from the rear space 40, and the air outlet 30a blows air to the front space 42. The blower 30 is, for example, an axial fan, and may be a thin fan mounted on a blower mounting hole of the bracket 22. The blower 30 is arranged at substantially the same height as the third subassembly 18c, and the outlet 30a is located behind the third subassembly 18c.
　整流板３２は、吹出口３０ａの周囲に沿って吹出口３０ａの下側に設けられている。整流板３２は、吹出口３０ａの全周のうち例えば１／２から１／４にわたって設けられている。整流板３２は、ブラケット２２の一部としてブラケット２２に一体形成されており、ブラケット２２の前面２２ａから前方に延出している。整流板３２は、送風機３０の下側に位置するので、可動灯具ユニット１８より下方、すなわち第３サブアセンブリ１８ｃより下方に位置し、灯具ボディ１２の底部に近接している。整流板３２の下面と灯具ボディ１２との間を通る空気流れを抑制するために、整流板３２と灯具ボディ１２の底部との隙間は、なるべく小さい（例えば、５ｍｍ以下）が望ましい。吹出口３０ａが円形であるため、整流板３２は、円筒状に湾曲しているが、平板など他の形状を有してもよい。 The rectifying plate 32 is provided below the outlet 30a along the periphery of the outlet 30a. The current plate 32 is provided, for example, over 1/2 to 1/4 of the entire circumference of the outlet 30a. The current plate 32 is formed integrally with the bracket 22 as a part of the bracket 22, and extends forward from a front surface 22 a of the bracket 22. Since the current plate 32 is located below the blower 30, it is located below the movable lamp unit 18, that is, below the third subassembly 18 c, and is close to the bottom of the lamp body 12. In order to suppress the air flow passing between the lower surface of the current plate 32 and the lamp body 12, the gap between the current plate 32 and the bottom of the lamp body 12 is desirably as small as possible (for example, 5 mm or less). Since the air outlet 30a is circular, the current plate 32 is curved in a cylindrical shape, but may have another shape such as a flat plate.
　また、ブラケット２２には、送風機３０による空気循環を促進するための開口部６４が送風機３０より上方に設けられている。開口部６４を通じて前方スペース４２から後方スペース４０へと空気が流れることができる。 開口 Further, an opening 64 for promoting air circulation by the blower 30 is provided in the bracket 22 above the blower 30. Air can flow from the front space 42 to the rear space 40 through the opening 64.
　図６に示されるように、送風機３０は、灯室１６内に空気流れ６６（実線の矢印で示す）を生成する。空気流れ６６は、送風機３０の吹出口３０ａから前方スペース４２に送出される。整流板３２が吹出口３０ａの下側に設けられ、そのため整流板３２より下方に向かう流れは抑制されるので、空気流れ６６は前方および上方へと流れる。空気流れ６６は、各サブアセンブリ（１８ａ～１８ｃ）の放熱部５６へと吹き付けられる。空気流れ６６は、放熱部５６と熱交換をしながら放熱部５６の近傍を通過し、放熱部５６から熱を運び去る。 As shown in FIG. 6, the blower 30 generates an air flow 66 (indicated by solid arrows) in the lamp room 16. The air flow 66 is sent from the outlet 30 a of the blower 30 to the front space 42. Since the current plate 32 is provided below the air outlet 30a, the flow downward from the current plate 32 is suppressed, so that the air flow 66 flows forward and upward. The air flow 66 is blown to the heat radiating portion 56 of each sub-assembly (18a to 18c). The air flow 66 passes near the heat radiating portion 56 while exchanging heat with the heat radiating portion 56 and carries away heat from the heat radiating portion 56.
　こうして放熱部５６を冷却した空気流れ６６は、開口部６４を通じて後方スペース４０へと戻る。送風機３０は、吸気口３０ｂから後方スペース４０の空気を吸い込み、空気流れ６６が送風機３０から再び前方に送出される。 空 気 The air flow 66 that has cooled the radiator 56 returns to the rear space 40 through the opening 64. The blower 30 sucks the air in the rear space 40 from the intake port 30b, and the air flow 66 is sent out from the blower 30 forward again.
　仮に、整流板３２が存在しなかったとすると、破線の矢印で図示されるように、送風機３０のごく近傍で吹出口３０ａから吸気口３０ｂへと流れが循環しうる。このような循環流れは、可動灯具ユニット１８の冷却への寄与が小さい。整流板３２は、こうした局所的な循環流を抑制し、可動灯具ユニット１８に向かう空気流れ６６を増加する。よって、整流板３２を設けることにより、車両用灯具１０の冷却効率が高まる。また、整流板３２は、ブラケット２２に一体形成されているので、整流板３２を別部品として用意する場合に比べて、製造コストを低減することができる。 Assuming that the rectifying plate 32 does not exist, the flow may circulate from the outlet 30a to the inlet 30b in the immediate vicinity of the blower 30, as shown by the dashed arrow. Such a circulating flow has a small contribution to the cooling of the movable lamp unit 18. The current plate 32 suppresses such local circulation flow and increases the air flow 66 toward the movable lamp unit 18. Therefore, by providing the current plate 32, the cooling efficiency of the vehicle lamp 10 is increased. Further, since the current plate 32 is formed integrally with the bracket 22, the manufacturing cost can be reduced as compared with the case where the current plate 32 is prepared as a separate component.
　なお、整流板３２の配置は、吹出口３０ａの下側には限られず、可動灯具ユニット１８と送風機３０との位置関係に応じて、吹出口３０ａの上方または側方など吹出口３０ａの周囲の一部に形成されてもよい。必要とされる場合には、整流板３２が、吹出口３０ａの全周を囲んでいてもよい。 Note that the arrangement of the current plate 32 is not limited to the lower side of the outlet 30a, but may be located above the outlet 30a or around the outlet 30a, such as the side, depending on the positional relationship between the movable lamp unit 18 and the blower 30. It may be formed partially. If necessary, the current plate 32 may surround the entire circumference of the outlet 30a.
　図７から図９は、実施の形態に係る車両用灯具１０の製造方法における各工程を示す概略斜視図である。まず、図７に示されるように、灯具ボディ１２が用意される。灯具ボディ１２には、可動灯具ユニット１８の光軸調整に使用される２本の調整ねじ６８が設けられている。２本の調整ねじ６８は水平方向に並んでいる。また、第１ワイヤーハーネス２４が装着されたブラケット２２が用意される（図３および図４参照）。ブラケット２２には、送風機３０、レベリングアクチュエータ３４、内部電子機器３６ａ、３６ｂが取り付けられ、これらと第１ワイヤーハーネス２４が予め接続されている。 FIGS. 7 to 9 are schematic perspective views showing steps in a method of manufacturing the vehicle lamp 10 according to the embodiment. First, as shown in FIG. 7, a lamp body 12 is prepared. The lamp body 12 is provided with two adjustment screws 68 used for adjusting the optical axis of the movable lamp unit 18. The two adjustment screws 68 are arranged in a horizontal direction. Further, the bracket 22 to which the first wire harness 24 is attached is prepared (see FIGS. 3 and 4). The blower 30, the leveling actuator 34, and the internal electronic devices 36a and 36b are attached to the bracket 22, and the first wire harness 24 is connected thereto in advance.
　図８に示されるように、灯具ボディ１２の前方にブラケット２２が配置される。ブラケット２２は、例えばねじ留めなど適宜の方法で灯具ボディ１２に固定される。また、外部電子機器２７が灯具ボディ１２の底面に取り付けられる。第１ワイヤーハーネス２４の第１コネクタ２４ａが、外部電子機器２７から延びる第２ワイヤーハーネス２６の相手コネクタ２６ａと接続される。接続された第１コネクタ２４ａおよび相手コネクタ２６ａは、ブラケット２２上のコネクタ保持構造２８にちょうど収まっている。 ブ ラ ケ ッ ト As shown in FIG. 8, the bracket 22 is disposed in front of the lamp body 12. The bracket 22 is fixed to the lamp body 12 by an appropriate method such as screwing. The external electronic device 27 is attached to the bottom surface of the lamp body 12. The first connector 24a of the first wire harness 24 is connected to the mating connector 26a of the second wire harness 26 extending from the external electronic device 27. The connected first connector 24 a and the mating connector 26 a are just fitted in the connector holding structure 28 on the bracket 22.
　ブラケット２２は前面２２ａを前に向けて灯具ボディ１２に固定されるので、第１ワイヤーハーネス２４の第１コネクタ２４ａは、作業者にとって手前側に配置される。よって、第１コネクタ２４ａと相手コネクタ２６ａとの接続作業は容易である。同様に、第２コネクタ２４ｂおよび第３コネクタ２４ｃも手前側に配置されるので、以降の接続作業が容易である。その他のコネクタ（２４ｄ～２４ｇ）を含む第１ワイヤーハーネス２４の大部分と、これらコネクタに予め接続された各機器は、ブラケット２２の背面２２ｂに装着されているから、ブラケット２２と灯具ボディ１２との間に収納されている。よって、これらは以降の作業の妨げにならない。 Because the bracket 22 is fixed to the lamp body 12 with the front surface 22a facing forward, the first connector 24a of the first wire harness 24 is arranged on the near side for the operator. Therefore, the connection work between the first connector 24a and the mating connector 26a is easy. Similarly, since the second connector 24b and the third connector 24c are also arranged on the near side, subsequent connection work is easy. Most of the first wire harness 24 including other connectors (24d to 24g) and each device connected in advance to these connectors are mounted on the back surface 22b of the bracket 22, so that the bracket 22, the lamp body 12, It is stored between. Therefore, they do not hinder subsequent work.
　また、灯具ボディ１２の２本の調整ねじ６８が送風機３０の両側に位置している。レベリングシャフト３８は、２本の調整ねじ６８のうち車幅方向内側に位置するほうの調整ねじ６８の鉛直方向上方に位置している。 Also, two adjusting screws 68 of the lamp body 12 are located on both sides of the blower 30. The leveling shaft 38 is located vertically above the adjustment screw 68 located on the inner side in the vehicle width direction of the two adjustment screws 68.
　次に、図９に示されるように、可動灯具ユニット１８がブラケット２２の前方に配置される。このとき、可動灯具ユニット１８は、２本の調整ねじ６８とレベリングシャフト３８の合計３つの支持点で支持されるようにして、灯具ボディ１２に支持される。レベリングアクチュエータ３４がレベリングシャフト３８を前後に進退させることによって、可動灯具ユニット１８は、灯具ボディ１２に対して傾動可能となっている。第１ワイヤーハーネス２４の第２コネクタ２４ｂは、可動灯具ユニット１８側の第３ワイヤーハーネス７０と接続される。 Next, as shown in FIG. 9, the movable lamp unit 18 is arranged in front of the bracket 22. At this time, the movable lamp unit 18 is supported by the lamp body 12 so as to be supported by a total of three support points of the two adjusting screws 68 and the leveling shaft 38. When the leveling actuator 34 moves the leveling shaft 38 back and forth, the movable lamp unit 18 can tilt with respect to the lamp body 12. The second connector 24b of the first wire harness 24 is connected to the third wire harness 70 on the movable lamp unit 18 side.
　続いて、固定灯具ユニット２０が、可動灯具ユニット１８に隣接してブラケット２２の前方に配置される。固定灯具ユニット２０は、例えばねじ留めなど適宜の方法で灯具ボディ１２に固定される。第１ワイヤーハーネス２４は、可動灯具ユニット１８の後方でブラケット２２の背面２２ｂに設けられ、固定灯具ユニット２０の後方でブラケット２２の背面２２ｂから前面２２ａへと延びている。第１ワイヤーハーネス２４の第３コネクタ２４ｃは、固定灯具ユニット２０側のワイヤーハーネスと接続される。さらに続いて、灯具ボディ１２に前面カバー１４が取り付けられる。その結果、図１および図２に示されるように、車両用灯具１０が得られる。 Next, the fixed lamp unit 20 is disposed in front of the bracket 22 adjacent to the movable lamp unit 18. The fixed lamp unit 20 is fixed to the lamp body 12 by an appropriate method such as screwing. The first wire harness 24 is provided on the rear surface 22 b of the bracket 22 behind the movable lamp unit 18, and extends from the rear surface 22 b of the bracket 22 to the front surface 22 a behind the fixed lamp unit 20. The third connector 24c of the first wire harness 24 is connected to the wire harness on the fixed lamp unit 20 side. Subsequently, the front cover 14 is attached to the lamp body 12. As a result, as shown in FIGS. 1 and 2, a vehicle lamp 10 is obtained.
　上述のように、第１ワイヤーハーネス２４の大半の部分がブラケット２２の背面２２ｂに装着されている。第１ワイヤーハーネス２４のうちブラケット２２の背面２２ｂに装着された部分は、ブラケット２２が灯具ボディ１２に取り付けられたとき、ブラケット２２と灯具ボディ１２との間の後方スペース４０に収められることになる。第１ワイヤーハーネス２４は、ブラケット２２の背面２２ｂから開口部２３を通じて前面２２ａへと案内されている。第１コネクタ２４ａ、第２コネクタ２４ｂ、第３コネクタ２４ｃを含む第１ワイヤーハーネス２４の残りの部分は、前方スペース４２に配置される。しかし、第１ワイヤーハーネス２４の残部は、固定灯具ユニット２０の後方に配置されているから、可動灯具ユニット１８の可動範囲の外側に配置されることになる。 As described above, most of the first wire harness 24 is mounted on the back surface 22 b of the bracket 22. The portion of the first wire harness 24 attached to the back surface 22 b of the bracket 22 is accommodated in the rear space 40 between the bracket 22 and the lamp body 12 when the bracket 22 is attached to the lamp body 12. . The first wire harness 24 is guided from the rear surface 22 b of the bracket 22 to the front surface 22 a through the opening 23. The remaining portion of the first wire harness 24 including the first connector 24a, the second connector 24b, and the third connector 24c is disposed in the front space 42. However, the remaining portion of the first wire harness 24 is disposed behind the fixed lamp unit 20, and thus is disposed outside the movable range of the movable lamp unit 18.
　可動灯具ユニット１８および固定灯具ユニット２０は、第１ワイヤーハーネス２４および第２ワイヤーハーネス２６を介して外部電子機器２７に接続される。同様に、送風機３０などブラケット２２に設置された各機器も、第１ワイヤーハーネス２４および第２ワイヤーハーネス２６を介して外部電子機器２７に接続される。よって、車両用灯具１０は、外部電子機器２７を通じて給電され、外部電子機器２７により制御されることができる。 The movable lamp unit 18 and the fixed lamp unit 20 are connected to the external electronic device 27 via the first wire harness 24 and the second wire harness 26. Similarly, each device installed on the bracket 22 such as the blower 30 is also connected to the external electronic device 27 via the first wire harness 24 and the second wire harness 26. Therefore, the vehicle lamp 10 is supplied with power through the external electronic device 27 and can be controlled by the external electronic device 27.
　以上説明したように、実施の形態に係る車両用灯具１０によると、第１ワイヤーハーネス２４は、可動灯具ユニット１８の後方でブラケット２２の背面２２ｂに設けられ、固定灯具ユニット２０の後方でブラケット２２の背面２２ｂから前面２２ａへと延びている。したがって、ブラケット２２を利用して、可動灯具ユニット１８の可動範囲を避けるように第１ワイヤーハーネス２４を配置することができる。そのため、可動灯具ユニット１８と第１ワイヤーハーネス２４との干渉による第１ワイヤーハーネス２４の損傷や断線のリスクを低減し、第１ワイヤーハーネス２４を保護することができる。 As described above, according to the vehicle lamp 10 according to the embodiment, the first wire harness 24 is provided on the back surface 22 b of the bracket 22 behind the movable lamp unit 18, and the bracket 22 is provided behind the fixed lamp unit 20. Extends from the back surface 22b to the front surface 22a. Therefore, the first wire harness 24 can be arranged using the bracket 22 so as to avoid the movable range of the movable lamp unit 18. Therefore, the risk of damage or disconnection of the first wire harness 24 due to interference between the movable lamp unit 18 and the first wire harness 24 can be reduced, and the first wire harness 24 can be protected.
　可動灯具ユニット１８とブラケット２２の間には、第３ワイヤーハーネス７０が配置されている。このように、一部の配線が、可動灯具ユニット１８の周囲に配置されてもよい。しかし、本実施の形態によれば、第１ワイヤーハーネス２４など他の配線は、可動灯具ユニット１８の可動範囲を避けて配置されるので、可動灯具ユニット１８の周囲に配置される配線は必要最小限とすることができる。このように配線を整理して配置したことにより、可動灯具ユニットとの間に起こりうる干渉による配線の損傷や断線のリスクを低減し、車両用灯具１０内の配線を保護することができる。 第 A third wire harness 70 is disposed between the movable lamp unit 18 and the bracket 22. In this way, some wiring may be arranged around the movable lamp unit 18. However, according to the present embodiment, the other wires such as the first wire harness 24 are arranged so as to avoid the movable range of the movable lamp unit 18, so that the wires arranged around the movable lamp unit 18 are the minimum necessary. Limit. By arranging and arranging the wirings in this way, the risk of wiring damage and disconnection due to interference that may occur with the movable lamp unit can be reduced, and the wiring in the vehicle lamp 10 can be protected.
　また、コネクタ保持構造２８は、ワイヤーハーネスのコネクタと相手コネクタとが正規に嵌合しているとき両コネクタを所定位置に保持するとともに、両コネクタが半嵌合であるとき所定位置から外れて位置するように構成されている。これにより、コネクタの接続作業に際して半嵌合品を容易に発見し、その場で修正することができる。そのため、車両用灯具１０の製造工程から、半嵌合品を検査する専用の工程を省略することができる。これは、車両用灯具１０の製造コストの低減に役立ちうる。 Further, the connector holding structure 28 holds both connectors in a predetermined position when the connector of the wire harness and the mating connector are properly fitted, and is positioned out of the predetermined position when both connectors are half-fitted. It is configured to be. As a result, a semi-fitted product can be easily found during the connector connection operation, and can be corrected on the spot. Therefore, a dedicated process for inspecting a semi-fitted product can be omitted from the manufacturing process of the vehicle lamp 10. This can help reduce the manufacturing cost of the vehicle lamp 10.
　さらに、ブラケット２２は、吹出口３０ａからの空気流が可動灯具ユニット１８に向かうように吹出口３０ａの周囲の少なくとも一部に形成された整流板３２を備える。これにより、送風機３０のごく近傍で生じうる局所的な循環流が抑制され、可動灯具ユニット１８および固定灯具ユニット２０に向かう空気流が増加され、車両用灯具１０の冷却効率が高まる。 ブ ラ ケ ッ ト Furthermore, the bracket 22 includes a rectifying plate 32 formed at least partially around the outlet 30a so that the airflow from the outlet 30a is directed to the movable lamp unit 18. This suppresses a local circulating flow that can occur very close to the blower 30, increases the airflow toward the movable lamp unit 18 and the fixed lamp unit 20, and increases the cooling efficiency of the vehicle lamp 10.
