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。
如图1至图7所示，本发明第一方面提供一种远光车灯光学元件，包括依次相连的远光入光部12、光通道11和远光出光部15，所述远光入光 部12设置为能够使射入的光线汇聚并出射至所述光通道11，并经所述光通道11射至所述远光出光部15；其中，还包括与所述光通道11相连的辅助点亮结构，所述辅助点亮结构包括辅助点亮入光部13和与所述辅助点亮入光部13相配合的辅助点亮出光部14，所述辅助点亮入光部13设置为能够使射入的光线经过至少一次反射后射至所述光通道11，并经所述光通道11射至所述辅助点亮出光部14。
本发明通过设置辅助点亮结构，使得在近光照明模式下，所述远光车灯光学元件所在的远光照明单元也能被点亮，从而能够提高车灯的整体造型美观度；通过设置辅助点亮出光部14，使其能够与远光出光部15分开设置，使得所述辅助点亮结构在配光过程中可调节的参数增多，能够提高其配光的灵活度，容易将辅助点亮结构的出射光线调节到想要的位置，从而能够实现更好的点亮效果。
具体地，所述辅助点亮入光部13包括第一反射面132和第二反射面133，所述第一反射面132能够将射入的光线反射至所述第二反射面133，所述第二反射面133能够将所述第一反射面132反射至第二反射面133的光线反射至所述光通道11，并经所述光通道11射至所述辅助点亮出光部14。其中，第一反射面132和第二反射面133可以为一体成型，也可以为分开设置，当第一反射面132和第二反射面133分开设置时，第二反射面133优选与光通道11一体成型，能够将第一反射面132的出射光线更高效地传输至光通道11，同时使得远光车灯光学元件的结构更加稳定。
优选地，如图1、图2和图4所示，所述第一反射面132位于所述第二反射面133上方，所述第一反射面132为向前凸出的曲面，使得经第一反射面132反射后的光线能够更好地射至第二反射面133，所述第二反射面133为由上向下向前倾斜的平面，结构简单，容易加工。当然，第二反射面133也可以为其它可以将光线反射至光通道11的曲面，使得经第二反射面133反射后的光线能够更多地射至光通道11，并经光通道11射至辅助点亮 出光部14。
具体地，如图1至图4所示，所述辅助点亮入光部13还包括入光面131，所述入光面131一侧可与所述第一反射面132相连，另一侧可与所述第二反射面133相连，所述第一反射面132能够将由所述入光面131射入的光线反射至所述第二反射面133，所述第二反射面133将射入的光线反射至所述光通道11，并经所述光通道11射至所述辅助点亮出光部14。其中，所述入光面131优选为平面，使得结构简单、容易制造，当然，也可以为向后凸出的曲面，或者也可以在入光面131处设置能够将光线进行汇聚的聚光结构，例如聚光杯结构，使得经入光面131射入的光线能够更多的射至第一反射面132，从而提高光线的利用率。
优选地，所述辅助点亮入光部13设在所述光通道11的后端且位于所述远光入光部12的上方；对应地，所述辅助点亮出光部14设在所述远光出光部15的上方且位于所述远光出光部15的后方，使得辅助点亮入光部13的出射光线能够经光通道11射至辅助点亮出光部14。所述辅助点亮入光部13位于所述远光入光部12的上方，能够使得辅助点亮结构的出射光线投射到配光屏幕水平轴线下方的区域内，也即投射到近光光形的区域内，从而不会影响近光照明。当然，所述辅助点亮入光部13也可以位于所述远光入光部12的下方、左侧或右侧，使得辅助点亮结构的出射光线投射到近光光形区域以外的不影响近光照明的区域。其中，辅助点亮结构的出射光线形成的光形的亮度较低，具体可以根据远光光形和近光光形的亮度、以及相关照明要求来确定，确保其亮度不会影响车辆的近光光形的光照强度和均匀性，也不会影响到附近其他车辆。辅助点亮出光部14设在远光出光部15的上方且位于远光出光部15的后方，使得辅助点亮出光部14与远光出光部15分开设置，使得所述辅助点亮结构在配光过程中可调节的参数增多，能够提高其配光的灵活度，容易将辅助点亮结构的出射光线调节到想要的位置，从而能够实现更好的点亮效果。
优选地，所述辅助点亮出光部14的出光面上设有凹凸结构141。所述凹凸结构141可以是如图5至图7所示的呈条纹状的凹凸结构141，也可以是呈网格状的凹凸结构141，还可以是呈锯齿状的凹凸结构141。通过设置该凹凸结构141，可以使得由辅助点亮出光部14的出光面射出的光线更加发散，从而使得经辅助点亮出光部14射出的光线更加均匀。其中，所述辅助点亮出光部14优选为与所述光通道11形成为一体的平面，使得经辅助点亮出光部14射出的光线更加发散和均匀。
在上述实施方式的基础上，具体地，所述远光入光部12为聚光杯结构，所述聚光杯结构的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；远光入光部12可以为实心体的聚光杯结构，也可以为具有凹腔的聚光杯结构，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；或者所述远光入光部12为向后凸出的凸起结构。所述远光入光部12的数量为一个或多个，当其为多个时，多个远光入光部12可以设置为一排，也可以设置为多排。
优选地，所述远光出光部15的出光面为与所述光通道11形成为一体的两侧向前弯曲的顺滑曲面，使得其能够与次级光学元件更好地配合，从而形成清晰的远光光形。
具体地，所述远光车灯光学元件的后端设有安装部16，所述安装部16上设有安装孔。通过设置安装部16，便于本发明的远光车灯光学元件的安装。更具体地，如图1和图2所示，所述远光车灯光学元件后端一体成型有所述安装部16，所述安装部16为U形安装板，所述U形安装板上设有多个所述安装孔，所述U形安装板上还设有定位销。
优选地，所述远光车灯光学元件为一体成型件，使得本发明远光车灯光学元件的集成化程度高，减少安装零部件的数量，保证各部件的相对位置精度，确保光形的稳定性，且便于加工成型，能够降低制造成本。
本发明第二方面提供一种车辆远光照明单元，如图8至图12所示，包 括第一方面所述的远光车灯光学元件，所述远光车灯光学元件前方设有透镜21，其后方分别设有远光光源5和辅助点亮光源6，所述远光光源5与所述远光入光部12对应设置，所述辅助点亮光源6与所述辅助点亮入光部13对应设置。在近光照明模式下，所述车辆远光照明单元只开启辅助点亮光源6，辅助点亮光源6发出的光线经辅助点亮入光部13反射至光通道11，并依次经光通道11、辅助点亮出光部14射至透镜21，最后经透镜21的出光面射出，使得车外的人看到近光照明模式下远光照明单元的透镜21也是发光的，从而使得在近光照明模式下，所述车辆远光照明单元也能被点亮。在远光照明模式下，开启远光光源5，所述远光光源5发出的光线经远光入光部12汇聚后射至光通道11，并依次经光通道11、远光出光部15射至透镜21，最后经透镜21的出光面射出形成远光光形，此时，辅助点亮光源6可以开启，也可以关闭。其中，辅助点亮光源6优选为亮度可以调节的光源，使得可以根据实际需要选择合适的亮度，以确保其亮度不会影响车辆的近光光形的光照强度和均匀性，也不会影响到附近其他车辆。
通过设置第一方面所述的远光车灯光学元件，使得在近光照明模式下，所述车辆远光照明单元也能被点亮，从而能够提高车灯的整体造型美观度。

优选地，所述支撑部22和所述透镜21为一体成型，可以通过嵌件注塑或双色注塑一体成型，且所述透镜21成型于所述支撑部22前端，通过设置支撑部22，便于透镜21的安装。其中，所述支撑部22可以为表面设 有遮光涂层的透光制件，也可以为不透光制件，从而能够减少从透镜21的出光面之外射出的杂散光，避免影响远光照明效果。
本发明第三方面提供一种车灯，包括第二方面所述的车辆远光照明单元。
通过设置第二方面所述的车辆远光照明单元，使得在近光照明模式下，所述车辆远光照明单元也能被点亮，从而能够提高车灯的整体造型美观度。
