相关申请的交叉引用
本申请要求2020年11月16日提交的中国专利申请202011280925.8的权益，该申请的内容通过引用被合并于本申请。
技术领域
本发明涉及车灯，具体地，涉及一种远近光一体车灯光学元件。本发明还涉及一种车灯模组、一种车灯和一种车辆。
背景技术
当今汽车的车灯呈现出明显的小型化趋势，这就要求车灯模组的结构更加精简化和集成化，车灯模组中各零部件的布置也更加紧凑。
中国专利CN106439672B公开了一种LED光源车灯模组，如图1所示，近光聚光器1和远光聚光器2上下设置，近光聚光器1和远光聚光器2的后端分别设置有近光LED电路板7和远光LED电路板6，近光LED电路板7和远光LED电路板6固定在散热器5上，透镜3安装在透镜卡圈4上，并通过透镜卡圈4固定在散热器5上，形成了一种结构紧凑的车灯模组。但该车灯模组的零件数量还是较多，车灯光学元件的集成度还不高。
为了车灯模组紧凑的结构和实现远近光光形的衔接，现有的车灯模组中各零件之间的间隙通常设置的较小。如图1所示的车灯模组中，近光聚光器1和远光聚光器2靠得很近，近光聚光器1前端下边界的截止线结构和远光聚光器2前端上边界的截止线结构接触安装，还形成了如下缺点：(1)如图2所示，在使用远光照明功能时，远、近光光源是同时打开的，近光聚光器1前端下边界的截止线结构对应形成了近光光形51的上边界截止线53，远光聚光器2前端的上边界的截止线结构对应形成了远光光形52的下端边界，近光光形51和远光光形52通过上述两个边界衔接。但这种光形的衔接没有光形之间的重叠过渡，在衔接处会产生衔接暗区54，使得远、近光之间的衔接不够好。(2)由于近光聚光器1和远光聚光器2前端相互接触，在车辆行驶发生振动时，近光聚光器1和远光聚光器2的前端接触处会发生相互撞击发生磨损，甚至出粉，使得正常的近光 光形和/或远光光形发生变化，甚至导致车灯模组因近光光形和/或远光光形不符合法规要求而失效。
现有的车灯光学元件已经不能适应当今车灯小型化的发展趋势需求，市场迫切需要一种集成度更高，远、近光光形衔接更好的车灯光学元件。
发明内容
本发明所要解决的技术问题是提供一种远近光一体车灯光学元件，该远近光一体车灯光学元件的集成度高，所形成的远、近光光形衔接好。

本发明还要解决的技术问题是提供一种车辆，其车灯的尺寸小，照明光形好。
为了解决上述技术问题，本发明一方面提供了一种远近光一体车灯光学元件，包括一体成型的近光入光部、远光入光部、第一通光部、第二通光部、第三通光部和透镜部；所述近光入光部位于所述第一通光部的后端，所述远光入光部位于所述第二通光部的后端，所述第二通光部位于所述第一通光部的下侧，所述第一通光部与所述第二通光部之间形成材料分界面，所述材料分界面上设有截止线结构，所述第三通光部位于所述第一通光部和所述第二通光部的前端，所述透镜部位于所述第三通光部的前端；所述第一通光部和所述第二通光部由不同的透明材料成型，且所述第一通光部的折射率大于所述第二通光部的折射率。
优选地，所述第三通光部和所述透镜部由同一种透明材料成型。在该优选技术方案中，第三通光部和透镜部采用同一种透明材料成型，能够避免在第三通光部与透镜部之间形成分界面，导致光线通过时产生反射，影响光效。另外，同一种材料的第三通光部和透镜部加工也更加方便。
进一步优选地，所述第一通光部、所述第三通光部和所述透镜部由同一种透明材料成型，所述第二通光部由另一种透明材料成型；所述第二通光部与所述第三通光部之间形成远光初级出光面，所述截止线结构形成于所述材料分界面的前边沿。在该优选技术方案中，同一种材料的第一通光部、第三通光部和透镜部， 减少了近光光线通过时的反射，提高了光效，也方便了加工。第二通光部与第三通光部之间的远光初级出光面有利于远光光线的再次配光。
进一步地，所述近光入光部和所述第一通光部由同一种透明材料成型，所述远光入光部和所述第二通光部由同一种透明材料成型。通过该优选技术方案，近光入光部与第一通光部之间，以及远光入光部与第二通光部之间均没有分界面，有利于提高远近光光线的光效。
优选地，所述近光入光部、所述远光入光部和所述第一通光部由同一种透明材料成型。在该优选技术方案中，由于通常入光部的结构比较复杂，近光入光部和远光入光部由同一种材料成型，加工更加方便，加工成本也较低。
作为一种优选方案，所述近光入光部、远光入光部和所述第二通光部由同一种透明材料成型。在该优选技术方案中，同样地，近光入光部和远光入光部由同一种材料成型，加工更加方便。

优选地，所述近光入光部的下侧和第一通光部下侧的后部设置有Ⅲ区结构，所述第二通光部的上侧的相应位置设置有对应的凹腔。通过该优选技术方案，通过近光入光部导入的近光光线中的一部分能够进入Ⅲ区结构，并通过Ⅲ区结构射出，经透镜部投射后形成近光Ⅲ区光线。
优选地，所述第一通光部由PC或者PMMA成型，所述第二通光部由硅胶成型。在该优选技术方案中，PC材料和PMMA材料的折射率均大于硅胶材料的折射率，并且，硅胶材料的耐温性能较高，在用于紧挨着光源的入光部时，能够提高入光部的耐温性，有助于降低入光部的受热变形。
本发明第二方面提供了一种车灯模组，该车灯模组包括光源模块和本发明第一方面所提供的远近光一体车灯光学元件。
本发明第三方面提供了一种车灯，该车灯中使用了本发明第二方面所提供的车灯模组。
本发明第四方面提供了一种车辆，该车辆使用了本发明第三方面所提供的车灯。
通过上述技术方案，本发明的远近光一体车灯光学元件，将近光入光部、远光入光部、第一通光部、第二通光部、第三通光部和透镜部集成到一个光学元件上，形成了同时具有近光光学通道、远光光学通道和透镜功能的光学元件，集成度更高，各光学部分之间的定位精度更高，所形成的近光光形和远光光形的稳定性更高。本发明的远近光一体车灯光学元件，第一通光部的折射率大于第二通光部的折射率，从第一通光部通过的光线照射到第一通光部和第二通光部之间的材料分界面时能够产生全反射，全部被反射回第一通光部，一方面提高了近光的光学效率，另一方面材料分界面上的截止线结构对应形成了近光明暗截止线，还避免了近光光线进入第二通光部，在远光光形区域形成杂散光；从第二通光部通过的光线照射到第一通光部和第二通光部之间的材料分界面时，一部分光线能够经分界面的折射后进入第一通光部继续向前传播，照射到远光光形和近光光形之间的过渡区域，改善远、近光光形之间的衔接。本发明的车灯模组，仅通过光源模块和本发明的远近光一体车灯光学元件就能够形成远近光光形，结构更加简单，不仅远、近光光形衔接好，而且，避免了传统车灯模组不同光学元件之间的定位误差，光形精度更好，稳定性也更高。本发明的车灯和车辆，由于使用了本发明的车灯模组和车灯，也具有上述优点。

下面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，本发明的保护范围并不局限于下述的具体实施方式。
如图3至图6所示，本发明的远近光一体车灯光学元件的一个实施例，包括一体成型的近光入光部11、远光入光部12、第一通光部21、第二通光部22、第三通光部23和透镜部3。近光入光部11成型于第一通光部21的后端，通过 近光入光部11能够导入近光光源发出的近光光线，并传递到第一通光部21中；远光入光部12成型于第二通光部22的后端，通过远光入光部12以能够导入远光光源发出的远光光线，并传递到第二通光部22中；第二通光部22成型于第一通光部21的下侧，且第三通光部23成型于第一通光部21和第二通光部22的前端，第一通光部21和第二通光部22中的光线均能够进入第三通光部23；第三通光部23的前端与透镜部3成型为一体，第三通光部23中的光线能够传递到透镜部3，由透镜出光面31射出，形成照明光形，照明光形包括近光光形和远光光形。第一通光部21与第二通光部22之间的分界面形成了材料分界面24，材料分界面24上设置有截止线结构241，由近光入光部11导入的光线经截止线结构241的遮挡后由透镜部3射出，形成带有明暗截止线的近光光形。由远光入光部12导入的光线由透镜部3射出，形成远光光形。第一通光部21和第二通光部22由不同的透明材料加工成型，并且，第一通光部21的折射率大于第二通光部22的折射率，这样，从第一通光部21中通过的近光光线照射到第一通光部21和第二通光部22之间的材料分界面24时能够产生全反射而反射回第一通光部21，减小了第一通光部21中近光光线的损失，提高了近光光效，并防止近光光线进入第二通光部22中，形成远光照明区域中的杂散光。由设定形状的材料分界面24形成的截止线结构241还能够对应形成近光明暗截止线。而从第二通光部22中通过的远光光线照射到第一通光部21和第二通光部22之间的材料分界面24时则不会产生全反射，这样，从第二通光部22中通过的光线中的一部分能够进入第一通光部12中，并通过透镜出光面31射出。近光入光部11和远光入光部12带有入光结构，入光结构可以是聚光杯，也可以是入光面为平面、凹面或者凸面的其它入光结构；近光入光部11和远光入光部12的入光结构可以相同，也可以不同。透镜部3的透镜出光面31可以为向前凸出的球面，也可以是向前凸出的椭球面或者自由曲面等。透镜部3能够起到普通透镜的作用，能够对通过的光线进行汇聚和投射，以形成符合法规要求的照明光形。本发明的远近光一体车灯光学元件可以通过嵌件注塑或者双色注塑的方式一体成型，也可以其他适合的方式一体成型。如图7所示，近光光源发出的光线由近光入光部11导入，并传输到第一通光部21，第一通光部21中的部分近光光线照射到第一通光部21和第二通光部22的分界面，也就是材料分界面24时会产生全反射，因而这部分近光光线全部被反射回第一通光部21而不能进入第二通光部22中，第一通光部 21中的近光光线经截止线结构241的遮挡后进入第三通光部23，并经过透镜部3的折射而投射出去，形成如图24中的带有明暗截止线53的近光光形51。如图8所示，远光光源发出的光线由远光入光部12导入，并传输到第二通光部22，第二通光部22中的远光光线照射到材料分界面24时不会产生全反射，其中的部分光线能够在材料分界面24发生折射而进入第一通光部21中。第二通光部22中的远光光线进入第三通光部23，并经过透镜部3的折射而投射出去，形成如图24中的远光光形52。进入第一通光部21中的远光光线通过第三通光部23的传输，并经过透镜部3投射至如图24中的远近光重叠区55。这样，当近光光源和远光光源同时发光时，就能够形成如图24所示的没有衔接暗区、远近光光形衔接良好的照明光形。
在本发明的远近光一体车灯光学元件的一些实施例中，如图3至图8所示，第三通光部23和透镜部3由同一种透明材料制成。同一种透明材料的第三通光部23和透镜部3可以一次性加工成型，加工更加方便。同一种透明材料的第三通光部23和透镜部3连接部位没有分界面，光线通过时不会因分界面的反射而产生光损，提高了光效。
在本发明的远近光一体车灯光学元件的一些实施例中，如图3至图13所示，第一通光部21、第三通光部23和透镜部3均由同一种透明材料制成，第二通光部22由另一种透明材料制成，第一种透明材料的折射率大于第二种透明材料的折射率。第一通光部21中的近光光线照射到材料分界面24时，能够产生全反射，第二通光部22中的远光光线照射到材料分界面24时，则不会产生全反射。第二通光部22与第三通光部23之间形成远光初级出光面221，远光光线通过远光初级出光面221时能够产生折射，因而，远光初级出光面221能够起到对远光进行再次配光的作用，也就是说，通过调整远光初级出光面221的形状，能够调节远光光形的光分布，使其符合法规要求。远光初级出光面221的形状可以根据配光的需要进行设置，优选设置为由前向后内凹的弧面。截止线结构241形成于材料分界面24的前边沿。截止线结构241可以由材料分界面24设置成与明暗截止线相对应的形状而成。
作为本发明的远近光一体车灯光学元件的一种具体实施方式，如图3-图6所示，近光入光部11、第一通光部21、第三通光部23和透镜部3由同一种透明材料制成，远光入光部12和第二通光部22由另一种透明材料制成。这样，由近 光入光部11、第一通光部21、第三通光部23和透镜部3组成的近光通道就由同一种透明材料制成，近光通道中没有材料的分界面形成的反射，近光的光效更高。在由远光入光部12、第二通光部22、第三通光部23和透镜部3组成的远光通道中，远光入光部12和第二通光部22由同一种透明材料制成，第三通光部23和透镜部3由另一种透明材料制成，远光通道中也仅存在第二通光部22和第三通光部23之间的远光初级出光面221。远光初级出光面221为两种不同透明材料的分界面，由于第二通光部22的折射率小于第三通光部23的折射率，远光光线从第二通光部22进入第三通光部23时不会产生全反射，但能够产生折射。这样，远光初级出光面221就能够起到对远光光形进行再次配光的作用。
作为本发明的远近光一体车灯光学元件的一种具体实施方式，如图17-图19所示，近光入光部11、远光入光部12、第一通光部21、第三通光部23和透镜部3由同一种透明材料制成，第二通光部22由另一种透明材料制成。这样，整个车灯光学元件除了第二通光部22外均由同一种透明材料制成，第二通光部22由另一种透明材料制成，而第二通光部22的结构比较简单，车灯光学元件的加工比较方便，加工成本也较低。远光入光部12与第二通光部22之间的交界面可以设置为垂直于远光通道方向的平面，以减少对所通过的远光光线的反射。也可以设置为特定的曲面，以对通过的光线进行相应的调整，提高光线的均匀性。
作为本发明的远近光一体车灯光学元件的另一种具体实施方式，如图20-图22所示，近光入光部11、远光入光部12和第二通光部22由同一种透明材料制成，第一通光部21、第三通光部23和透镜部3由另一种透明材料制成。近光入光部11与第一通光部21之间的分界面可以设置为垂直于近光通道方向的平面，以减少近光光线通过时的反射，也可以设置为特定的曲面，以对通过的光线进行相应的调整，提高光线的均匀性。由于近光入光部11和远光入光部12的结构通常比较复杂，由同一种透明材料制作的近光入光部11和远光入光部12可以一次注塑成型，使得车灯光学元件的加工更加方便。
在本发明的远近光一体车灯光学元件的一些实施例中，如图14-图16所示，第三通光部23为空腔结构。空腔结构可以设置为第三通光部23下部盲孔状的空腔区231，在空腔区231的两侧为形成在第一通光部21和第二通光部22与透镜部3之间的支撑边框232，在空腔区231的顶部也形成为第一通光部21与透镜部3之间的支撑边框232。空腔结构也可以设置为位于第三通光部23中间部位 的上下通透的空腔区231，在空腔区231的两侧为形成在第一通光部21和第二通光部22与透镜部3之间的支撑边框232。空腔区231的后端与第一通光部21和第二通光部22之间以及空腔区231的前端与透镜部3之间均形成了能够调整光形分布的配光面，增加了车灯光学元件的配光参数。同时，空腔区231的存在还能够节省制作车灯光学元件的原料，减轻车灯光学元件的重量。
在本发明的远近光一体车灯光学元件的一些实施例中，如图9和图10所示，第二通光部22上侧的前端设置有凸起的50L结构222，50L结构222可以由与第二通光部22相同的材料形成，在第一通光部21的下侧与50L结构222相对应的位置设置有与50L结构222形状相对应的凹窝。50L结构222与对应的凹窝紧密接触，近光光线通过第一通光部21时，50L结构222能够对通过的近光光线进行折射，使得光线偏离近光光形中的50L区域，降低50L区域的亮度，使得近光光形的50L暗区的亮度符合法规要求。
在本发明的远近光一体车灯光学元件的一些实施例中，如图11-图13所示，近光入光部11和第一通光部21下侧的后部设置有Ⅲ区结构25。具体地，近光入光部11设置有近光聚光杯，近光聚光杯的下部向前延伸，形成聚光杯延伸部251，第一通光部21下侧的后部设置有与聚光杯延伸部251相连接的Ⅲ区通光部252，Ⅲ区通光部252的前端形成为Ⅲ区出光面253。第二通光部22的上侧与Ⅲ区结构25相对应位置设置有与Ⅲ区结构25的外形相对应的Ⅲ区凹腔223。近光光线从近光聚光杯导入时，部分近光光线通过聚光杯延伸部251进入Ⅲ区通光部252，并从Ⅲ区出光面253射出，进入第二通光部22的内部，通过远光初级出光面221、第三通光部23和透镜部3，由透镜出光面31射出，形成照射道路标记牌的近光Ⅲ区光线。
作为本发明的远近光一体车灯光学元件的一种具体实施方式，第一通光部21由PC材料或者PMMA材料制作而成，第二通光部22由硅胶材料制作而成。PC和PMMA的折射率均大于硅胶的折射率，在PC或者PMMA中传输的光线照射到PC与硅胶的分界面或者PMMA与硅胶的分界面时能够产生全反射，在硅胶中传输的光线照射到PC与硅胶的分界面或者PMMA与硅胶的分界面时则不会产生全反射。而硅胶的耐温性能更好，更能够耐受光源产生的较高的温度。
如图23所示，本发明的车灯模组的一个实施例，其中的光学结构仅包含光源模块4和本发明任一实施例的远近光一体车灯光学元件，模组的结构更加简 单。光源模块4上设置有与近光入光部11上入光结构数量相同的近光光源，近光光源发出的光线能够经过远近光一体车灯光学元件的传输和投射，形成如图24中所示的近光光形51。光源模块4上设置有与远光入光部12上入光结构数量相同的远光光源，远光光源发出的光线能够经过远近光一体车灯光学元件的传输和投射，形成如图24中所示的远光光形52。光源模块4上的近光光源和远光光源能够分别进行控制，当近光光源单独打开时，所形成的近光光形51能够用于车辆的近光照明；当光源模块4上的近光光源和远光光源同时打开时，近光光形51与远光光形52相互组合，形成如图24所示的用于车辆远光照明的光形。由于使用了本发明的远近光一体车灯光学元件，远近光通道的定位精度更高，近光光形51和远光光形52的稳定性更高，并且能够在近光光形51与远光光形52之间形成远近光重叠区55，避免了在近光光形51与远光光形52之间存在的衔接暗区，两者衔接良好，照明效果更好。
本发明所提供的远近光一体车灯光学元件，将由近光入光部11、远光入光部12、第一通光部21、第二通光部22、第三通光部23和透镜部3集成为一体的远近光一体车灯光学元件，车灯光学元件的集成度更高，远近光通道的定位精度和稳定性也更高。第一通光部21的折射率大于第二通光部22的折射率，从第一通光部21中通过的近光光线照射在第一通光部21与第二通光部22之间的材料分界面24上时能够产生全反射，提高了近光的光效，并能够通过材料分界面24上的截止线结构241形成近光明暗截止线，还能够避免近光光线进入远光通道形成杂散光；从第二通光部22中通过的远光光线照射在第一通光部21与第二通光部22之间的分界面上时能够折射进入第一通光部21，经透镜部3投射至近光光形与远光光形之间的远近光重叠区55，克服了传统远近光光形之间存在衔接暗区的缺陷。在本发明的远近光一体车灯光学元件的优选实施例中，硅胶材料成型的入光部具有更好的耐温性能，能够防止入光部工作在光源产生的较高的温度环境下产生变形。空腔结构的第三通光部23能够增加本发明的远近光一体车灯光学元件的配光参数。50L结构和Ⅲ区结构的设置增加了本发明的远近光一体车灯光学元件的功能，进一步提高了本发明的远近光一体车灯光学元件的集成度。本发明的车灯模组，结构更加简单，体积更小，光形更加稳定，照明效果也更好。
本发明的车灯和本发明的车辆，分别使用了本发明任一实施例的车灯模组 和车灯，也具有上述优点。
在本发明的描述中，参考术语“一个实施例”、“一些实施例”、“一种具体实施方式”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本发明中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于此。在本发明的技术构思范围内，可以对本发明的技术方案进行多种简单变型，包括各个具体技术特征以任何合适的方式进行组合，为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。但这些简单变型和组合同样应当视为本发明所公开的内容，均属于本发明的保护范围。
