【発明の属する技術分野】
本発明は、車両用ランプ装置に関する。
【０００２】
【従来の技術】
自動車の前部には、例えばフォグランプ、デイタイムランニングランプ（ＤＲＬ）、曲路灯等のランプが設置される。また、ランプの中には、回動機構により、ステアリング角度やターンシグナルスイッチ等に連動して水平方向で回動し、光照射方向を必要な角度だけ車両の旋回方向へ変化させるようにしたものもある（例えば、特許文献１参照。）。
【０００３】
【特許文献１】
特開平１１−２４５７１６号公報。
【０００４】
【発明が解決しようとする課題】
しかしながら、このような従来の構造にあっては、例えば車両の前部に複数のランプを設置しようとする場合、設置するランプの数の分だけ広い設置スペースが必要となり、車両の構造によっては、そのスペースの確保が困難である。また、そのランプが回動する構造の場合は、それぞれのランプに回動機構が必要となり、スペースの確保が更に困難になると共に車体重量の増加も招く。
【０００５】
本発明は、このような従来の技術に着目してなされたものであり、設置するランプの数を増やしても設置スペースを増やす必要がなく、或いは増やしたランプが回動する構造でも、駆動機構を増やす必要のない車両用ランプ装置を提供するものである。
【０００６】
【課題を解決するための手段】
請求項１の発明にあっては、駆動機構により回動軸を中心にして正逆方向に回動可能な回動体を車体に設け、該回動体の回動方向における異なる位置に複数のランプを設け、回動体を回動させることにより、所定のランプを車両前方へ向けて点灯可能である車両用ランプ装置であって、車両の旋回方向に連動して回動体を水平方向で回動させ、ランプの光照射方向を車両の旋回方向へ可変とすることを特徴とする。
【０００８】
請求項２の発明にあっては、回動体の少なくとも一部に回動軸を中心にした円筒側面を有し、該円筒側面に複数のランプの照射部を設けたことを特徴とする。
【０００９】
請求項３の発明にあっては、ランプの照射部が回動体の円筒側面から突出しないことを特徴とする。
【００１０】
請求項４の発明にあっては、ランプの一つがＬＥＤランプであることを特徴とする。
【００１１】
請求項５の発明にあっては、ランプの一つがプロジェクタランプであることを特徴とする。
【００１２】
【発明の効果】
請求項１に記載の発明によれば、１つの回動体に複数のランプを設け、回動体を回動させることにより、所定のランプだけを車両前方へ向けて点灯させるようにしたため、一組の回動体と駆動機構のスペースだけあれば良く、設置するランプの数が増えても、それ以上設置スペースを増やす必要はない。
【００１３】
また、請求項１に記載の発明によれば、点灯させるランプを選択するために回動体を回動させる駆動機構を利用して、点灯中のランプの光照射方向を車両の旋回方向に応じて変化させることができる。従って、設置されるランプの複数が回動する構造であっても、駆動機構は１つで済み、設置スペースを増加する必要はない。
【００１４】
請求項２に記載の発明によれば、回動体の円筒側面にランプの照射部を設けた構造のため、回動体を回動させることにより、各ランプを同じ位置で点灯させることができ、車体への組み込みも容易である。
【００１５】
請求項３に記載の発明によれば、ランプの照射部が回動体の円筒側面から突出しないため、回動体の円筒側面と車体との隙間を小さくした状態で、円筒側面の必要な部分だけを車体から露出させることができる。従って、回動体と円筒側面の隙間から埃や水が侵入しづらくなる。
【００１６】
請求項４に記載の発明によれば、ランプの一つとして設置されるＬＥＤランプは全体が薄型のため、回動体に設置しても、他のランプの設置の邪魔にならない。
【００１７】
請求項５に記載の発明によれば、ランプの一つとして設置されるプロジェクタランプは照射部としての集光レンズが小さいため、円筒側面に設置し易い。
【００１８】
【発明の実施の形態】
以下、この発明の一実施形態を図１〜図８に基づいて説明する。自動車の前部におけるバンパの下部には、本実施形態に係るランプ装置１が、左右に一対設置されている。このランプ装置１は、曲路灯として使用されるプロジェクタランプ２と、デイタイムランニングランプ（ＤＲＬ）として使用されるＬＥＤランプ３との２つを備えた構造になっている。
【００１９】
まず、このランプ装置１の構造としては、回動体４を備えている。回動体４は、約２４０°の角度範囲の円筒側面５と、それに対応する上下面を有している。回動体４の上下面の中心には回動軸６、７がそれぞれ形成されている。回動体４の上下の回動軸６、７は、車体に固定されたフレーム８に形成された上下の支持孔９、１０へ回動自在に挿入されている。
【００２０】
回動体４の下側の回動軸７は、駆動機構１１に連結されている。駆動機構１１は、モータ１２と、減速ギア部１３と、出力軸１４とから構成されており、出力軸１４が回動体４の下側の回動軸７と結合されている。従って、モータ１２を正逆方向へ回動させることにより、回動体４を左右に必要な角度だけ回動させることができる。駆動機構１１は、下側からブラケット１５により覆われている。
【００２１】
そして、このように左右に回動自在な回動体４は、その円筒側面５の一部を車体前部のパネル１６に形成された窓１７から前方へ露出させた状態になっている。図６〜図９はパネル１６の一部だけを図示している。パネル１６の窓１７の縁部と、回動体４との隙間Ｓは小さく、ここから埃や水が侵入しづらくなっている。
【００２２】
回動体４の内部には、下側の回動軸７に相当する部分に、概略楕円反射面を有するリフレクタ１８と、その第一焦点Ｐ１に位置するバルブ１９とが設置されている。リフレクタ１８の反射先の円筒側面５には凹んだ状態の開口２０が形成され、そこに集光レンズ２１が設置されている。この集光レンズ２１の先端は、円筒側面５の表面と一致しており、円筒側面５から突出しない。このリフレクタ１８、バルブ１９、集光レンズ２１によりプロジェクタランプ２が構成される。バルブ１９からの光は、リフレクタ１８で反射された後、第二焦点Ｐ２を経て、集光レンズ２１より照射される。
【００２３】
このような構造のプロジェクタランプ２のため、「照射部」としての集光レンズ２１の径Ｄ（図４参照）は小さく、円筒側面５に設置し易い。また、この集光レンズ２１が円筒側面５から突出しないため、円筒側面５とパネル１６との隙間Ｓを小さくするうえで支障にならない。
【００２４】
また、円筒側面５には、集光レンズ２１と９０°相違する位置に別の開口２２が形成され、そこにＬＥＤランプ３が設けられている。ＬＥＤランプ３は、円筒側面５と同じ円筒表面を有するアウタレンズ２３を「照射部」として円筒側面５の開口２２に嵌合させ、内部には面状に配したＬＥＤ２４が設けられている。このＬＥＤランプ３は、光源としてＬＥＤ２４を利用しているため、全体が薄型で、回動体４に設置しても、他のプロジェクタランプ２の邪魔にならない。このＬＥＤランプ３のアウタレンズ２３も円筒側面５から突出していないため、円筒側面５とパネル１６との隙間Ｓを小さくするうえで支障にならない。
【００２５】
そして、回動体４の円筒側面５に各ランプ２、３の照射部をそれぞれ設けたため、回動体４を回動させることにより、各ランプ２、３を同じ位置に露出させることができ、車体への組み込みも容易である。
【００２６】
このように、回動体４の円筒側面５には２つのランプ２、３が設置されており、フォグランプとしてのプロジェクタランプ２を使用する場合は、駆動機構１１により、回動体４を回動させて、プロジェクタランプ２の集光レンズ２１をパネル１６の窓１７から露出させ、点灯させれば良い。このプロジェクタランプ２を使用する場合は、駆動機構１１がステアリングに設けられた図示せぬ舵角センサーからの信号により制御される。すなわち、直線路走行時は、舵角がゼロのため、集光レンズ２１が真っ直ぐ前方を向いた状態となり（図６参照）、曲路走行時は、車両の旋回方向に向けてステアリングの舵角に相当する分だけ回動体４が回動し、集光レンズ２１からの光照射方向を車両の旋回方向へ変化させることができる（図７参照）。
【００２７】
そして、昼間時において、デイタイムランニングランプとしてのＬＥＤランプ３を利用する場合は、回動体４を９０°回動させて、ＬＥＤランプ３をパネル１６の窓１７から露出させ、点灯すれば良い（図８参照）。
【００２８】
以上説明したように、この実施形態によれば、１つの回動体４に２つのランプ２、３を設け、回動体４を回動させることにより、必要なランプだけを前方へ向けて点灯させるため、設置するランプ２、３が２つでも、一組の回動体４と駆動機構１１を設けるスペースだけあれば良い。また、この回動体４内に組み込み可能であれば、３つ以上のランプを設けることも可能で、その場合も、既存の設置スペース以上にスペースを拡大する必要はない。
【００２９】
更に、点灯させるランプを選択するために回動体４を回動させる駆動機構１１を利用して、点灯中のランプの光照射方向を車両の旋回方向に応じて変化できるようになっているため、仮に設置されるランプのうちの複数が、それぞれ車両旋回方向へ回動させる構造であっても、駆動機構１１は１つで済み、設置スペースの増加はない。

Japanese Patent Application Laid-Open No. 11-245716.
[0004]
[Problems to be solved by the invention]
However, in such a conventional structure, for example, when installing a plurality of lamps at the front of the vehicle, a large installation space is required for the number of lamps to be installed, and depending on the structure of the vehicle, It is difficult to secure the space. Further, in the case of a structure in which the lamp is rotated, a rotation mechanism is required for each lamp, and it becomes more difficult to secure a space and an increase in the weight of the vehicle body is caused.
[0005]
The present invention has been made paying attention to such a conventional technique, and it is not necessary to increase the installation space even if the number of lamps to be installed is increased, or the drive mechanism has a structure in which the increased lamps rotate. It is an object to provide a vehicular lamp device that does not need to be increased.
[0006]
[Means for Solving the Problems]
In the first aspect of the invention, the vehicle body is provided with a rotating body that can be rotated in the forward and reverse directions around the rotation axis by the drive mechanism, and a plurality of lamps are provided at different positions in the rotating direction of the rotating body. A vehicle lamp device capable of lighting a predetermined lamp toward the front of the vehicle by rotating the rotating body, wherein the rotating body is rotated in the horizontal direction in conjunction with the turning direction of the vehicle; The light irradiation direction of the lamp is variable in the turning direction of the vehicle .
[0008]
The invention according to claim 2 is characterized in that at least a part of the rotating body has a cylindrical side surface with the rotation axis as a center, and a plurality of lamp irradiation portions are provided on the cylindrical side surface.
[0009]
The invention of claim 3 is characterized in that the irradiation part of the lamp does not protrude from the cylindrical side surface of the rotating body.
[0010]
The invention according to claim 4 is characterized in that one of the lamps is an LED lamp.
[0011]
The invention according to claim 5 is characterized in that one of the lamps is a projector lamp.
[0012]
【The invention's effect】
According to the first aspect of the present invention, since a plurality of lamps are provided on one rotating body and only the predetermined lamps are lit toward the front of the vehicle by rotating the rotating body, Only the space for the rotating body and the drive mechanism is required, and even if the number of lamps to be installed is increased, it is not necessary to further increase the installation space.
[0013]
According to the first aspect of the present invention, the light irradiation direction of the lamp that is lit is set according to the turning direction of the vehicle by using a drive mechanism that rotates the rotating body to select the lamp to be lit. Can be changed. Therefore, even if a plurality of installed lamps rotate, only one drive mechanism is required, and there is no need to increase the installation space.
[0014]
With the invention according to claim 2, since the structure provided with the irradiation of the lamp to the cylindrical side surface of the rotating body, by rotating the rotating body, it is possible to turn on the respective lamp in the same position, the vehicle body Easy to incorporate into
[0015]
According to the third aspect of the present invention, since the irradiation part of the lamp does not protrude from the cylindrical side surface of the rotating body, only a necessary portion of the cylindrical side surface is provided in a state where the gap between the cylindrical side surface of the rotating body and the vehicle body is reduced. It can be exposed from the car body. Accordingly, it is difficult for dust and water to enter from the gap between the rotating body and the cylindrical side surface.
[0016]
According to the fourth aspect of the present invention, since the LED lamp installed as one of the lamps is thin as a whole, even if it is installed on the rotating body, it does not interfere with the installation of other lamps.
[0017]
According to the fifth aspect of the present invention, the projector lamp installed as one of the lamps is easy to install on the cylindrical side surface because the condensing lens as the irradiation unit is small.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. A pair of lamp devices 1 according to the present embodiment are installed on the left and right at the lower part of the bumper in the front part of the automobile. The lamp device 1 has a structure including two projector lamps 2 used as a curved lamp and an LED lamp 3 used as a daytime running lamp (DRL).
[0019]
First, the structure of the lamp device 1 includes a rotating body 4. The rotating body 4 has a cylindrical side surface 5 having an angle range of about 240 ° and upper and lower surfaces corresponding thereto. Rotating shafts 6 and 7 are formed at the centers of the upper and lower surfaces of the rotating body 4, respectively. The upper and lower rotary shafts 6 and 7 of the rotary body 4 are rotatably inserted into upper and lower support holes 9 and 10 formed in a frame 8 fixed to the vehicle body.
[0020]
A rotating shaft 7 on the lower side of the rotating body 4 is connected to the drive mechanism 11. The drive mechanism 11 includes a motor 12, a reduction gear unit 13, and an output shaft 14, and the output shaft 14 is coupled to the rotating shaft 7 below the rotating body 4. Therefore, by rotating the motor 12 in the forward and reverse directions, the rotating body 4 can be rotated by a necessary angle to the left and right. The drive mechanism 11 is covered with a bracket 15 from below.
[0021]
In this way, the rotating body 4 that can rotate left and right is in a state in which a part of the cylindrical side surface 5 is exposed forward from a window 17 formed in the panel 16 at the front of the vehicle body. 6 to 9 show only a part of the panel 16. A gap S between the edge of the window 17 of the panel 16 and the rotating body 4 is small, and it is difficult for dust and water to enter from here.
[0022]
Inside the rotating body 4, a reflector 18 having a substantially elliptical reflecting surface and a valve 19 positioned at the first focal point P <b> 1 are installed in a portion corresponding to the lower rotating shaft 7. A concave opening 20 is formed in the cylindrical side surface 5 of the reflector 18 where the light is reflected, and a condenser lens 21 is provided there. The tip of the condensing lens 21 coincides with the surface of the cylindrical side surface 5 and does not protrude from the cylindrical side surface 5. The reflector 18, the bulb 19, and the condenser lens 21 constitute a projector lamp 2. The light from the bulb 19 is reflected by the reflector 18 and then irradiated from the condenser lens 21 through the second focal point P2.
[0023]
Because of the projector lamp 2 having such a structure, the diameter D (see FIG. 4) of the condenser lens 21 as the “irradiation unit” is small and can be easily installed on the cylindrical side surface 5. In addition, since the condenser lens 21 does not protrude from the cylindrical side surface 5, there is no problem in reducing the gap S between the cylindrical side surface 5 and the panel 16.
[0024]
Further, another opening 22 is formed in the cylindrical side surface 5 at a position that is 90 ° different from the condensing lens 21, and the LED lamp 3 is provided there. In the LED lamp 3, an outer lens 23 having the same cylindrical surface as the cylindrical side surface 5 is fitted as an “irradiation part” into the opening 22 of the cylindrical side surface 5, and an LED 24 arranged in a planar shape is provided inside. Since the LED lamp 3 uses the LED 24 as a light source, the entire LED lamp 3 is thin and does not interfere with other projector lamps 2 even when installed on the rotating body 4. Since the outer lens 23 of the LED lamp 3 does not protrude from the cylindrical side surface 5, there is no problem in reducing the gap S between the cylindrical side surface 5 and the panel 16.
[0025]
And since the irradiation part of each lamp | ramp 2 and 3 was each provided in the cylindrical side surface 5 of the rotation body 4, by rotating the rotation body 4, each lamp | ramp 2 and 3 can be exposed to the same position, and to a vehicle body Is easy to incorporate.
[0026]
Thus, the two lamps 2 and 3 are installed on the cylindrical side surface 5 of the rotating body 4. When the projector lamp 2 as a fog lamp is used, the rotating body 4 is rotated by the drive mechanism 11. The condenser lens 21 of the projector lamp 2 may be exposed from the window 17 of the panel 16 and lighted. When the projector lamp 2 is used, the drive mechanism 11 is controlled by a signal from a steering angle sensor (not shown) provided in the steering. That is, when traveling on a straight road, the steering angle is zero, so that the condenser lens 21 faces straight forward (see FIG. 6), and when traveling on a curved road, the steering angle of the steering toward the turning direction of the vehicle. The rotating body 4 rotates by an amount corresponding to, and the direction of light irradiation from the condenser lens 21 can be changed to the turning direction of the vehicle (see FIG. 7).
[0027]
When the LED lamp 3 is used as a daytime running lamp at daytime, the rotating body 4 is rotated 90 ° to expose the LED lamp 3 from the window 17 of the panel 16 and light up ( (See FIG. 8).
[0028]
As described above, according to this embodiment, two lamps 2 and 3 are provided on one rotating body 4, and only the necessary lamps are lit forward by rotating the rotating body 4. Even if there are two lamps 2 and 3 to be installed, it suffices if there is only a space for providing a set of the rotating body 4 and the drive mechanism 11. Further, if it can be incorporated in the rotating body 4, it is possible to provide three or more lamps, and in that case, it is not necessary to expand the space beyond the existing installation space.
[0029]
Furthermore, since the drive mechanism 11 that rotates the rotating body 4 is used to select the lamp to be lit, the light irradiation direction of the lit lamp can be changed according to the turning direction of the vehicle. Even if a plurality of lamps to be installed are each configured to rotate in the vehicle turning direction, only one drive mechanism 11 is required, and there is no increase in installation space.
