技术领域
本发明涉及车灯，具体地，涉及一种车辆前照灯光学系统。此外，本发明还涉及一种车辆前照灯及车辆。
背景技术
目前，车灯越来越趋向于小型化和造型多样化的发展。但是，在现有汽车车灯照明光学系统中，远近光的实现方式主要是通过透镜式和反射式两种，受限于透镜或反射镜的尺寸，其车灯远近光模组的用于出光的出光口的上下开口尺寸很难做到很小，从而限制了汽车车灯造型的小型化和多样化设计。
另外，汽车车灯需要进行调光，由于车灯越来越趋向于小型化，使得造型空间越来越小，从而导致传统的调光机构与车灯灯壳发生干涉而无法进行调光，影响到部分零部件的布局，同时也给车灯的设计带来了较大的局限性。

以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。
本发明提供一种车辆前照灯光学系统，包括多个模组和设于各所述模组前方的配光镜4，所述多个模组包括至少一个远光模组1、至少一个主近光模组3、至少一个辅助近光模组2，所述配光镜4为窄长形配光镜，各所述模组沿着所述配光镜4的长度方向间隔设置，其中，各所述模组的出光口的上下开口尺寸都很小，即各所述模组均为小开口模组。
通过设置多个小开口模组，使得车辆前照灯光学系统的上下高度能够做到很小，能够与窄长形配光镜4相适应，使得车辆前照灯整体外观呈窄长形，能够在造型上提高视觉效果，从而实现车辆前照灯小型化和造型多样化的设计；通过设置远光模组1、主近光模组3和辅助近光模组2，能够同时实现远光、主近光和辅助近光的照明功能，满足车辆前照灯功能多样化的设计需求。其中，如图17和图18所示，远光模组1形成远光光形b，主近光模组3和辅助近光模组2配合形成近光光形a，主近光模组3形成主近光光形a1，即近光中心区域光形，辅助近光模组2形成辅助近光光形a2，即近光展宽区域光形。
如图3至图7所示，所述远光模组1包括远光光学元件和至少一个远光光源1141，所述远光光学元件包括远光通光部111和出光部112，所述远光通光部111后端设有至少一个远光聚光部110，所述远光聚光部110、远光通光部111和出光部112依次连接且一体成型，所述远光聚光部110与所述远光光源1141一一对应，所述远光光源1141发出的光线经所述远光聚光部110汇聚后，并依次经所述远光通光部111和所述出光部112射出形成远光光形b，远光光形b最后经配光镜4射出，配光镜4能够调节远光光形b的照度和均匀性。
通过设置远光聚光部110和远光通光部111，能够对远光光源1141发出的光线在上下方向上进行很好的汇聚，使得出光部112的出光面的上下高度可以做到很小，并且远光聚光部110和远光通光部111的上下高度也可以做到很小，从而使得整个远光模组的上下高度能够做到很小，从而实现远光模组的小开口设计；通过将远光聚光部110、远光通光部111和出光部112一体成型，即将初级光学元件和次级光学元件集成为一体，集成化程度高，减少了零部件的数量，使得远光模组体积减小，且仅需一次安装即可，避免了二次安装误差，能够保证两者的相对位置精度，从而更好地确保光形的稳定性。
其中，所述远光聚光部110可以有多种形式，例如，远光聚光部110可以为实心体的聚光杯结构，其外部轮廓面为由后向前口径逐渐增大的曲面，其入光面可以为平面，也可以为曲面；或者为具有凹腔的聚光杯结构，其外部轮廓面为由后向前口径逐渐增大的曲面，其入光端设有凹腔，凹腔开口朝后开设，凹腔内设有向后凸出的凸起；或者远光聚光部110为向后凸出的凸起结构。远光聚光部110优选为向后凸出的凸起结构。当然，该远光聚光部1102可以为多个，多个远光聚光部110可以设置为一排，也可以设置为多排。
具体地，所述出光部112具有远光出光面1120，所述远光出光面1120为凸透镜出光面，使得远光光源1141发出的光线依次经远光聚光部110、远光通光部111和出光部112后形成远光光形b。
优选地，所述远光通光部111外表面设有不透光层1110，能够减少从出光部112的远光出光面1120之外射出的杂散光，避免影响远光照明效果。其中，所述不透光层1110与所述远光通光部111优选为双色注塑一体成型，加工方便，使得不透光层1110与远光通光部111的连接更牢靠，无需进行装配，减少了装配零部件的数量。
优选地，所述远光光源1141适于独立控制亮灭，使得在远光照明时，通过控制各个远光光源1141的亮灭，来控制车灯的照射区域，以避开对向行驶车辆所在区域，避免产生炫目的问题，从而达到智能防炫目的效果，实现ADB远光照明，其形成的ADB光形如图19所示。
进一步地，所述远光模组1还包括远光线路板114和远光散热器113，所述远光光源1141安装在远光线路板114上，所述远光光学元件和远光线路板114均安装在远光散热器113上。
如图14至图16所示，所述主近光模组3包括近光光学元件和至少一个近光光源351，所述近光光学元件包括光通道33，所述光通道33包括形成为一体的第一光通道331和第二光通道332，所述第一光通道331后端 一体成型有至少一个近光聚光部32，所述第二光通道332前端形成有近光出光面34，所述近光聚光部32与所述近光光源351一一对应；所述近光聚光部32和第一光通道331均位于所述近光出光面34的光轴340上方，且所述近光聚光部32的光轴320相对于所述近光出光面34的光轴340倾斜设置，所述第一光通道331的下表面形成为反射部3311，所述反射部3311与所述第二光通道332的后端面相交处设有截止部3312，所述近光光源351发出的光线经所述近光聚光部32汇聚后，依次经所述第一光通道331和第二光通道332，并经所述近光出光面34射出形成主近光光形a1，主近光光形a1最后经配光镜4射出，配光镜4能够调节主近光光形a1的照度和均匀性。
通过设置近光聚光部32和光通道33，能够对近光光源351发出的光线在上下方向上进行很好的汇聚，使得近光出光面34的上下高度可以做到很小，并且近光聚光部32和光通道33的上下高度也可以做到很小，从而使得整个主近光模组3的上下高度能够做到很小，从而实现主近光模组3的小开口设计；通过设置形成为一体的近光聚光部32和光通道33，将初级光学元件和次级光学元件集成为一体，集成化程度高，减少了零部件的数量，使得主近光模组3的体积减小，且仅需一次安装即可，避免了二次安装误差，能够保证两者的相对位置精度，从而更好地确保光形的稳定性；通过将近光聚光部32和第一光通道331均设在近光出光面34的光轴340上方，且近光聚光部32的光轴320相对于近光出光面34的光轴340倾斜设置，使得近光聚光部32汇聚的光线能够依次经第一光通道331和第二光通道332，并经近光出光面34射出形成主近光光形a1，还能够使得第一光通道331的出射光线更多的射入第二光通道332并通过近光出光面34射出，从而提高光效，并且能够节省材料，降低生产成本。
其中，近光光源351发出的光线的具体路径为：近光聚光部32汇聚的光线一部分进入第一光通道331后直接射至第二光通道332，并经近光出光面34射至水平0度线的下方区域，另一部分光线射至第一光通道331的下表面，这部分光线能够经反射部3311反射至第二光通道332，并经近光出光面34射至水平0度线的下方区域，还有一部分光线经截止部3312射至第二光通道332，并经近光出光面34射出后形成位于水平0度线附近的近光截止线，从而近光聚光部32汇聚的光线最终经近光出光面34射出形成如图17所示的具有明暗截止线的主近光光形a1。由此，通过设置反射部3311，使得射至第一光通道331下表面的光线能够反射至第二光通道332，并经近光出光面34射出，能够增加进入第二光通道332的光线；通过设置截止部3312，截止部3312与近光截止线的形状相适应，使得射至截止部3312的光线经近光出光面34射出后形成近光截止线，无需另外采用遮光板进行遮挡形成截止线，同时也无需设置驱动机构来驱动遮光板实现远近光切换，消除了机械故障，减少了零部件，精简了结构，使得空间利用效率和配光效率更高。
需要说明的是，近光聚光部32和近光出光面34均具有焦点，近光聚光部32的光轴320是指过近光聚光部32的焦点的轴线，近光出光面34的光轴340是指过近光出光面34的焦点沿前后方向延伸的轴。近光出光面34可以为凸透镜出光面，也可以为菲涅尔透镜出光面。截止部3312设在近光出光面34的焦点处，使得近光聚光部32汇聚的光线能够更加集中地射向截止部3312，形成具有清晰明暗截止线的主近光光形a1。截止部3312可以根据实际需要设置为具有左右高低落差的形状或者直线形状或其它满足照明需求的形状。
可选地，近光聚光部32可以有多种形式，例如，近光聚光部32可以为实心体的聚光杯结构，其外部轮廓面为由后向前口径逐渐增大的曲面，其入光面可以为平面，也可以为曲面；或者为具有凹腔的聚光杯结构，其外部轮廓面为由后向前口径逐渐增大的曲面，其入光端设有凹腔，凹腔开口朝后开设，凹腔内设有向后凸出的凸起；或者近光聚光部32为向后凸出的凸起结构。该近光聚光部32可以为多个，多个近光聚光部32可以设置为一排，也可以设置为多排。
进一步地，所述主近光模组3还包括近光线路板35和近光散热器31，所述近光光源351安装在近光线路板35上，所述近光光学元件和近光线路板35均安装在近光散热器31上。
如图8至图13所示，所述辅助近光模组2包括辅助近光初级光学元件、透镜和至少一个辅助近光光源2141，所述辅助近光初级光学元件包括辅助近光通光部216和至少一个辅助近光聚光部215，所述辅助近光通光部216后端与所述辅助近光聚光部215一体成型，所述辅助近光通光部216前端形成有辅助近光初级出光面2160，所述辅助近光聚光部215与所述辅助近光光源2141一一对应，所述辅助近光光源2141发出的光线经所述辅助近光聚光部215汇聚后射至所述辅助近光通光部216，经所述辅助近光初级出光面2160射出后照射到所述透镜上，并经所述透镜折射后形成辅助近光光形a2，辅助近光光形a2最后经配光镜4射出，配光镜4能够调节辅助近光光形a2的照度和均匀性。
通过设置辅助近光通光部216和辅助近光聚光部215，能够对辅助近光光源2141发出的光线在上下方向上 进行很好的汇聚，使得透镜的出光面的上下高度可以做到很小，并且辅助近光通光部216和辅助近光聚光部215的上下高度也可以做到很小，从而使得整个辅助近光模组2的上下高度能够做到很小，从而实现辅助近光模组2的小开口设计。
其中，所述辅助近光聚光部215可以有多种形式，例如，辅助近光聚光部215可以为实心体的聚光杯结构，其外部轮廓面为由后向前口径逐渐增大的曲面，其入光面可以为平面，也可以为曲面；或者为具有凹腔的聚光杯结构，其外部轮廓面为由后向前口径逐渐增大的曲面，其入光端设有凹腔，凹腔开口朝后开设，凹腔内设有向后凸出的凸起；或者辅助近光聚光部215为向后凸出的凸起结构。当然，该辅助近光聚光部215可以为多个，多个辅助近光聚光部215可以设置为一排，也可以设置为多排。
具体地，所述辅助近光通光部216前端下边沿设有辅助近光截止线结构，辅助近光截止线结构与辅助近光截止线的形状相适应，使得射至辅助近光截止线结构的光线经其所述透镜射出后形成辅助近光截止线，所述辅助近光截止线结构优选设在所述透镜的焦点处，使得辅助近光聚光部215汇聚的光线能够更加集中地射向辅助近光截止线结构，形成具有清晰明暗截止线的辅助近光光形a2。其中，辅助近光截止线结构可以根据实际需要设置为具有左右高低落差的形状或者直线形状或其它满足照明需求的形状。
具体地，所述透镜后端设有用于支撑该透镜的支撑部211，所述支撑部211内设有贯通其前后两端的空腔，所述辅助近光光学元件位于所述空腔内。所述支撑部211与所述透镜优选为一体成型，支撑部211优选为不透光材质，能够减少从透镜的出光面之外射出的杂散光，避免影响辅助近光照明效果，当然，支撑部211也可以为表面设有遮光涂层的透光材质。
进一步地，所述辅助近光模组2还包括辅助近光线路板214和辅助近光散热器213，所述辅助近光光源2141安装在辅助近光线路板214上，所述辅助近光初级光学元件、透镜和辅助近光线路板214均安装在辅助近光散热器213上。
图8至图11所示为辅助近光模组2的一种具体结构，其中，所述透镜为弧形透镜212，所述弧形透镜212的纵截面为平凸面或双凸面，所述弧形透镜212由所述纵截面以其焦点所在的竖直轴线为旋转轴旋转而成。通过设置弧形透镜212，能够使其折射出的光线扩散范围进一步增大，从而使得辅助近光光源2141发出的光线经其折射后形成展宽角度较宽的辅助近光光形a2，从而能够拓宽车辆前方的横向照明区域，为驾驶者提供较宽的照明视野。辅助近光模组模组2与主近光照明模组3相配合，使得车辆前方的照明区域更宽、更亮。
优选地，所述辅助近光通光部216下表面设有III区结构217，所述III区结构217具有III区下表面2171，所述III区下表面2171与所述辅助近光通光部216下表面之间形成III区出光面2172。辅助近光聚光部215汇聚的部分光线射至III区结构217，经III区出光面2172射出后进入弧形透镜212，并经弧形透镜212折射后形成近光III区光形。

作为一种具体实施例，如图1和图2所示，所示车辆前照灯光学系统包括三个远光模组1、一个主近光模组3和两个辅助近光模组2，两个辅助近光模组2位于该三个远光模组1和该主近光模组3之间，三个远光模组1分别为第一远光模组11、第二远光模组12和第三远光模组13，两个辅助近光模组2分别为第一辅助近光模组21和第二辅助近光模组22，第一辅助近光模组21的结构如图8至图11所示，所述辅助近光通光部216下表面设有III区结构217，第二辅助近光模组22的结构如图12至图13所示。
上述各模组均包括散热器，优选地，至少一个所述模组的散热器后端设有调光系统5。
具体地，如图20至图38所示，所述调光系统5包括左右调光机构和上下调光机构，所述左右调光机构包括固定架52和沿左右方向设置的左右调光螺钉51，固定架52与车辆前照灯的壳体固定连接，或者与车辆前照灯的相对于车辆前照灯的壳体固定不动的其它零部件固定连接，所述左右调光螺钉51可转动安装在所述固定架52上，所述上下调光机构包括支撑架54、沿上下方向设置的上下调光螺钉53以及与所述上下调光螺钉53螺纹连接的螺纹连接件55，所述支撑架54滑动安装在所述固定架52上并与所述左右调光螺钉51的螺杆513螺纹连接，所述上下调光螺钉53可转动安装在所述支撑架54上，所述螺纹连接件55固定在所述散热器上；转动所述 上下调光螺钉53，所述螺纹连接件55上下移动以带动所述散热器上下移动，以使所述散热器绕上下调光轴线620旋转，即整个模组绕上下调光轴线620旋转进行上下调光；转动所述左右调光螺钉51，所述上下调光机构左右移动，所述上下调光机构的上下调光螺钉53带动所述散热器左右移动，以使所述散热器绕左右调光轴线560旋转，即整个模组绕左右调光轴线560旋转进行左右调光。
本发明的调光系统5设在散热器后端，不会影响到模组其它零部件的设计及布局，且调光系统5整体结构紧凑，占用空间小，基本不增加模组的上下和左右方向的尺寸，从而不会影响车辆前照灯整体的造型设计，给车辆前照灯的设计带来了更大的设计空间；通过设置左右调光螺钉51和上下调光螺钉53，可以转动调光螺钉带动散热器左右或上下旋转，从而带动整个模组左右或上下旋转，实现模组的左右和上下调光，调光方便。
具体地，所述左右调光螺钉51的螺杆513和所述支撑架54螺纹配合，所述支撑架54上设有与左右调光螺钉51的螺杆513相配合的螺纹孔543，所述支撑架54滑动安装在所述固定架52上，所述固定架52和所述支撑架54中的一者沿左右方向设有滑块522，另一者设有与所述滑块522相配合的滑槽542。如图24至图26、图36和图37所示，所述固定架52上沿左右方向设有滑块522，所述支撑架54上设有与所述滑块522相配合的滑槽542，转动所述左右调光螺钉51，所述左右调光螺钉51的螺杆513带动所述支撑架54左右移动，即带动所述上下调光机构左右移动，通过设置滑块522和滑槽542，使得支撑架54能够沿着固定架52左右滑动，从而使得支撑架54左右移动更顺畅，左右调光更加方便容易。
具体地，如图20至图26、图32至图34所示，所述散热器上设有第一散热翅片61，所述螺纹连接件55的左右两侧固定在所述第一散热翅片61上，其前后两侧与所述第一散热翅片61之间均设有间隙551。具体地，所述螺纹连接件55的左右两侧均设有贯通其前后两侧的通槽552，所述第一散热翅片61上设有安装孔，所述螺纹连接件55插入所述安装孔内并通过所述通槽552卡接在所述安装孔的左右侧壁上，且所述螺纹连接件55的前后两侧与所述安装孔的前后侧壁之间均设有间隙551。由于上下调光螺钉53不能上下移动，因此，当转动上下调光螺钉53，上下调光螺钉53的螺杆533能够带动螺纹连接件55上下移动，而螺纹连接件55卡接在第一散热翅片61上，进而能够带动散热器上下移动，使得散热器绕上下调光轴线620旋转进行上下调光。另外，由于左右调光时，左右调光螺钉51带动支撑架54左右移动，该螺纹连接件55也随支撑架54一起左右直线移动，而散热器绕左右调光轴线560沿弧线转动，因此，散热器相对螺纹连接件55在前后方向上是有运动分量的，如果螺纹连接件55的前后左右都与散热器固定，散热器就会实现不了转动，因此，该螺纹连接件55的左右两侧固定在第一散热翅片61上，其前后两侧与第一散热翅片61之间存在间隙551，没有接触，使得散热器能更好地转动。当然，所述螺纹连接件55也可以通过其它结构使其左右两侧固定在所述第一散热翅片61上，例如，所述螺纹连接件55的左右两侧均设有卡接块，所述安装孔的左右两侧壁上均设有卡接槽，所述螺纹连接件55通过卡接块卡接在所述卡接槽内以固定在所述第一散热翅片61上，其同样属于本发明的保护范围。另外，所述螺纹连接件55上设有螺纹孔，所述螺纹连接件55的前后两侧均设有与所述螺纹孔相连通的开口，以使螺纹连接件55容易发生变形，便于插入第一散热翅片61上的安装孔，从而与第一散热翅片61卡接。
具体地，如图24和图25所示，所述调光系统5还包括旋转架56，所述旋转架56上沿上下方向设有旋转轴，所述固定架52上设有与所述旋转轴相配合的通孔523，所述左右调光轴线560为所述旋转轴的中心轴线，所述散热器适于带动所述旋转架56左右移动，以使所述旋转架56带动所述散热器绕所述左右调光轴线560旋转。优选地，如图25至图27、图29至图31所示，所述旋转轴为螺钉柱562，所述螺钉柱562通过螺钉563安装在所述通孔523内，从而避免螺钉柱562从固定架52的通孔523内脱出，便于旋转架56在固定架52上的安装定位。更优选地，所述螺钉柱562外表面设有多个与所述通孔523线接触的筋条5621，能够保证螺钉柱562的中心轴线与通孔523的中心轴线相重合，使得螺钉柱562在通孔523内能够更好地绕其自身中心轴线转动。
具体地，如图23、图29和图32所示，所述散热器上设有第二散热翅片62，所述第二散热翅片62的左右两侧分别设有同轴的圆柱凸块621，所述旋转架56的左右两端分别设有与对应侧的所述圆柱凸块621相配合的圆孔561，所述上下调光轴线620为所述圆柱凸块621的中心轴线。上下调光时，转动上下调光螺钉53，上下调光螺钉53的螺杆533带动散热器上下移动，由于固定架52与旋转架56连接，旋转架56与第二散热翅片62连接，固定架52限制了散热器的上下移动，从而使得第二散热翅片62的左右两侧的圆柱凸块621在圆孔561内绕其自身中心轴线转动，即散热器绕上下调光轴线620旋转，从而实现上下调光。
进一步地，所述第二散热翅片62和所述旋转架56中的一者设有凸块622，另一者设有与所述凸块622相配合的凹槽564，以使所述散热器和所述旋转架56能够同步转动以及沿左右方向同步移动。如图27至图29所示，第二散热翅片62上设有沿前后方向延伸的凸块622，旋转架56上设有与所述凸块622相配合的沿前后方向 延伸的凹槽564。左右调光时，转动左右调光螺钉51，左右调光螺钉51的螺杆513带动上下调光机构左右移动，上下调光机构的上下调光螺钉53带动散热器左右移动，第二散热翅片62上的凸块622带动凹槽564进而带动旋转架56左右同步移动，由于旋转架56上沿上下方向设有旋转轴，固定架52上设有与旋转轴相配合的通孔523，固定架52限制了旋转架56的左右移动，从而使得旋转架56绕左右调光轴线560旋转，旋转架56上的凹槽564带动凸块622进而带动散热器绕左右调光轴线560同步旋转，从而实现左右调光。
当然，也可以不设第二散热翅片62，可以在第一散热翅片61的左右两侧分别设同轴的圆柱凸块621，以及在第一散热翅片61上设沿前后方向延伸的凸块622，以与旋转架56相配合，同样能够实现上下和左右调光。更进一步地，也可以不用设旋转架56，可以在固定架52的左右两端分别设与对应侧的圆柱凸块621相配合的圆孔561，在第一散热翅片61上沿上下方向设旋转轴，在固定架52上设与旋转轴相配合的通孔523，也同样能够实现上下和左右调光，这些变型方式也同样属于本发明的保护范围。
优选地，如图25、图35至图38所示，所述左右调光螺钉51和所述上下调光螺钉53的螺钉头上均设有限位面，所述左右调光螺钉51和所述上下调光螺钉53的螺杆上均设有卡槽，所述左右调光螺钉51通过其限位面515和安装在其卡槽5131内的止退垫圈514安装在所述固定架52上，使得左右调光螺钉51能够在固定架52上转动，不能沿左右方向移动，所述上下调光螺钉53通过其限位面534和安装在其卡槽5331内的止退垫圈535安装在所述支撑架54上，使得上下调光螺钉53能够在支撑架54上转动，不能沿上下方向移动。
优选地，如图20、图21、图25、图35和图37所示，所述左右调光螺钉51的螺钉头上设有左右调光工具插孔511，调光工具插入左右调光工具插孔511，通过转动调光工具带动左右调光螺钉51转动，所述上下调光螺钉53的螺钉头上设有上下调光工具插孔531，所述调光工具插入上下调光工具插孔531，通过转动调光工具带动上下调光螺钉53转动。所述调光工具插孔可以为多边形孔，例如六角形孔，也可以为条形孔或十字形孔，调光工具可以为与调光工具插孔相配合的螺丝刀，通过将螺丝刀插入调光工具插孔，转动螺丝刀来带动左右调光螺钉51和上下调光螺钉53转动。
优选地，如图20至图26、图35至图37所示，所述左右调光螺钉51的螺钉头外圈设有左右调光齿轮512，所述固定架52上设有左右调光工具导套521，调光工具插入左右调光工具导套521，通过拨动左右调光齿轮512带动左右调光螺钉51转动，上下调光螺钉53的螺钉头外圈设有上下调光齿轮532，所述支撑架54上设有上下调光工具导套541，所述调光工具插入上下调光工具导套541，通过拨动上下调光齿轮532带动上下调光螺钉53转动。通过设置调光工具导套，便于调光工具插入，从而能更好地拨动调光齿轮转动。调光工具可以为与调光齿轮相配合的螺丝刀，螺丝刀头部与调光齿轮啮合，通过将螺丝刀插入调光工具导套与调光齿轮啮合，转动螺丝刀来带动左右调光螺钉51和上下调光螺钉53转动。
