相关申请的交叉引用
本申请要求2020年09月29日提交的中国专利申请202011050923.X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，涉及一种车灯光学元件。本发明还涉及一种车灯模组和一种车灯。
背景技术
汽车的车灯造型越来越窄长化，即上下尺寸越来越小，左右尺寸越来越大，随着车灯的小型化，对于车灯前后尺寸也要求越来越小。上述上下、左右、前后均和整车方位一致。
车灯光学元件是一种用于收集、传导、汇聚光源发出的光线，以形成所需的光分布的光学元件。为适应车灯外形的发展趋势，车灯光学元件也呈现出上下尺寸越来越小、左右尺寸越来越大、前后尺寸越来越小的趋势。
聚光器是一种常用的尺寸较小的车灯光学元件。通常的聚光器的结构如图1所示，进光口6设置在聚光器1a的后端，出光口7设置在聚光器1a的前端，光源设置在进光口6处，光源发出的光线经过进光口6进入导光部4，经过导光部4的传输和折射，从出光口7射出。这样的结构不仅使得聚光器1a的前后尺寸较长，而且，由于光源需要设置在进光口6的后方，光源及与光源连接的散热器结构进一步增加了车灯的前后尺寸，限制了车灯前后尺寸的减少。
近来也出现了一种弯折式的聚光器，如图2所示，进光口6设置在聚光 器1b的下端，出光口7设置在聚光器1b的前端，光源设置在进光口6处，光源发出的光线从进光口6进入导光部4，经过反射面的反射后从出光口7射出。这样的结构减小了聚光器1b的前后尺寸，但上下设置的聚光杯2使得聚光器1b的上下尺寸较大，而且，在进光口6的下方还需要设置光源及与光源连接的散热器结构，进一步增加了车灯的上下尺寸。
现有的车灯光学元件已经不能适应当今车灯造型发展趋势的需求，阻碍了车灯造型的发展，市场迫切需要一种应用于前后尺寸和上下尺寸均较小的窄长造型车灯的车灯光学元件。
发明内容
本发明所要解决的技术问题是提供一种车灯光学元件，该车灯光学元件的前后尺寸和上下尺寸均较小。
本发明进一步所要解决的技术问题是提供一种车灯模组，该车灯模组的前后尺寸和上下尺寸均较小。
本发明还要解决的技术问题是提供一种车灯，该车灯具有前后尺寸和上下尺寸较小，左右尺寸较大的扁平状造型。
为了解决上述技术问题，本发明一方面提供了一种车灯光学元件，包括入光部、出光面和反射面，所述入光部设置在所述出光面的侧方，所述反射面设置为能够将从所述入光部射入的光线反射向所述出光面，以能够通过所述出光面射出。
优选地，所述反射面为相对于所述入光部和所述出光面倾斜设置的平面。在该优选技术方案中，倾斜设置的平面状的反射面能够将从入光部射入的光线反射向出光面，并以总体上垂直于出光面的方向由出光面射出，出射光线分布较均匀。
优选地，所述入光部包括分设在所述出光面两侧方的第一入光部和第二入光部，所述反射面包括能够将从所述第一入光部射入的光线反射向所述出 光面的第一反射面和能够将从所述第二入光部射入的光线反射向所述出光面的第二反射面。在该优选技术方案中，通过分设在出光部的两侧方的第一入光部和第二入光部能够导入更多的光源发出的光线，提高从出光面射出的光线的强度。同时，在保证出光强度的基础上，能够减少设置在同一侧的入光部的数目，进一步减小车灯光学元件的前后尺寸。
优选地，本发明的车灯光学元件还包括透镜部分；所述透镜部分与所述出光面一体连接，能够将从所述出光面射出的光线投射出去，形成照明光形。通过该优选技术方案，透镜部分能够实现普通透镜的功能，将射向出光面的光线投射出去，形成照明光形。出光面与透镜部分的一体连接，不仅能够提高透镜部分与出光面之间相对位置的稳定性，而且能够简化车灯模组的结构。
进一步优选地，所述透镜部分包括透镜入光面和透镜出光面，所述透镜入光面与所述出光面一体连接。通过该优选技术方案，透镜入光面与出光面的一体连接结构，使得入射光线经过反射面的反射后，能够直接进入透镜部分，减少了通常的车灯光学元件出光面和透镜的入光面对光线的反射作用，能够提高车灯模组的光效。
进一步地，所述透镜入光面与所述出光面相重合。在该优选技术方案中，透镜入光面与出光面相重合的结构，使得透镜部分与车灯光学元件的其他部分融合为一个整体，提高了车灯光学元件的整体稳定性，并能够简化车灯光学元件的制造工艺。
优选地，所述透镜入光面大于所述出光面，所述出光面一体连接在所述透镜入光面的上部或者下部。通过该优选技术方案，透镜入光面除了与出光面连接的部分外，还在连接部分的下方或者上方保留有部分透镜入光面，能够通过该部分透镜入光面接受其它入射光线，使得透镜部分还能够用于实现其它照明功能。
优选地，所述出光面上设有截止线结构。在该优选技术方案中，截止线结构能够形成近光照明光形或远光照明光形中的明暗截止线，实现近光照明 功能或远光照明功能。
本发明第二方面提供了一种车灯模组，该车灯模组中使用了本发明第一方面所提供的车灯光学元件。
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。
通过上述技术方案，本发明的车灯光学元件，将入光部设置在出光面的侧方，减小了车灯光学元件的前后尺寸和上下尺寸，使得车灯光学元件具有前后尺寸和上下尺寸较小，左右尺寸较大的扁平状结构。同时，使得车灯的光源和光源的散热器结构也能够设置在车灯光学元件的侧方，能够更好地适应当今的扁平状的车灯造型趋势。将入光部分设于出光面左右两侧的结构，能够进一步缩短车灯光学元件的前后尺寸，适应车灯造型需要。在出光面一体连接透镜部分的设置，使得本发明的车灯光学元件同时实现了透镜的功能，且结构稳定性更高，车灯结构也更加简单。透镜部分透镜入光面的一部分与出光面一体连接的结构，使得车灯光学元件的透镜部分可以作为普通透镜来使用，用于实现其它照明功能。本发明的车灯模组，采用了本发明的车灯光学元件，前后尺寸和上下尺寸更小，左右尺寸更大，符合当今车灯的造型趋势。本发明的车灯由于使用了本发明的车灯模组，也具有上述优点。
有关本发明的其它技术特征和技术效果，将在下文的具体实施方式中进一步说明。

具体实施方式
在本发明中，在未作相反说明的情况下，使用的方位词如“前、后、上、下、左、右”所指示的方位或位置关系是基于本发明的车灯正常安装在车辆上后的方位或位置关系。其中，方位词“前”所指示的方向为车辆的正常行驶方向。对本发明的车灯光学元件和车灯模组及其零部件的方位或位置关系的描述与其实际使用中的安装方位一致。
术语“第一”、“第二”仅用于描述的目的，而不能理解为指示或暗示相对重要性或隐含指明所指示的技术特征的数量，因此，限定有“第一”、“第二”的特征可以明示或隐含地包括一个或更多个所述特征。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“设置”或“连接”应做广义理解，例如，术语“连接”可以是固定连接，也可以是可拆卸连接，或者是一体连接；可以是直接连接，也可以是通过中间媒介间接连接，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
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，本发明的车灯光学元件的一个实施例，包括入光部1、出光面2和反射面3。入光部1为适于导入光源所发出的光线的结构，具体地，入光部1可以是聚光杯结构，还可以是入光面为平面、凹面或者凸面的其它入光结构。入光部1可以仅设置一个，也可以设置有多个。出光面2为适于导出光线的平面或者曲面，适应当今车灯的扁平状的造型，出光面2通常设 置为长条形。入光部1设置在出光面2的侧方。通常地，出光面2设置在车灯光学元件的前端，入光部1可以设置在车灯光学元件的左侧，也可以设置在车灯光学元件的右侧。反射面3为能够将从入光部1射入的光线反射向出光面2的反射面，优选地，可以在反射面3上设置增反膜来提高反射率。反射面3可以设置为平面、柱面、凹面、凸面或者是自由曲面。如图7所示，入光部1能够导入光源5发出的光线，使得光源5发出的光线射向反射面3，并经过反射面3反射后射向出光面2，并通过出光面2射出。在车灯光学元件具有多个入光部1时，不同的光源5发出的光线能够从不同的入光部1导入，经车灯光学元件的传输和折射、反射面3的反射后，通过出光面2射出，形成分布均匀的出射光线。
在本发明的车灯光学元件的一些实施例中，如图3、图4、图6-图8所示，反射面3为倾斜设置在入光部1和出光面2相对侧的平面。本实施例的车灯光学元件整体设置为棱柱形，反射面3、入光部1和出光面2形成在棱柱的不同侧面上，反射面3相对于入光部1所在的面和出光面2均倾斜设置。根据入光部1所在的面与出光面2之间的夹角的不同或者根据车灯配光过程中对光线传输方向的不同要求，反射面3可以与入光部1所在的面及出光面2呈现不同的倾斜度。平面状的反射面3能够将从入光部1照射来的光线反射向出光面2，并以总体垂直于出光面的方向从出光面2射出。平面状的反射面3设置简单，同时不改变入射光线原有的光分布。
作为本发明的车灯光学元件的一种具体实施方式，如图9-图11所示，入光部1包括分别设置的第一入光部11和第二入光部12；反射面3也包括分别设置的第一反射面31和第二反射面32。第一入光部11设置在车灯光学元件的右侧，第一反射面31相对于第一入光部11和出光面2设置，能够将经由第一入光部11导入的光线反射向出光面2，并通过出光面2射出。第二入光部12设置在车灯光学元件的左侧，第二反射面32相对于第二入光部12和出光面2设置，能够将经由第二入光部12导入的光线反射向出光面2，并通过 出光面2射出。经由第一入光部11导入的光线与经由第二入光部12导入的光线可以照射到出光面2的不同区域，相互组合形成分布均匀的光线通过出光面2射出。经由第一入光部11导入的光线与经由第二入光部12导入的光线也可以各自照射在整个出光面2上，二者相互叠加形成分布均匀的光线通过出光面2射出。将入光部1分别设置在车灯光学元件的左右两侧的结构可以减少在车灯光学元件的同一侧设置的入光部1的数量，进一步减小车灯光学元件的前后尺寸。
在本发明的车灯光学元件的一些实施例中，如图12-图17所示，本发明的车灯光学元件还包括透镜部分4。透镜部分4与出光面2一体连接，由入光部1导入的光线经反射面3反射后射向透镜部分4，在透镜部分4的汇聚作用下投射出去，形成照明光形。透镜部分4可以与车灯光学元件的其他部分(下文称为聚光器部分)使用相同的透明材料一体浇注而成。在车灯光学元件上一体设置透镜部分4，能够代替传统的车灯模组中的透镜，简化车灯模组的结构，提高车灯模组结构的稳定性。
在本发明的车灯光学元件的一些实施例中，如图12-图17所示，透镜部分4包括透镜入光面41和透镜出光面42，车灯光学元件聚光器部分的出光面2与透镜部分的透镜入光面41一体连接，使得聚光器部分的出光面2仅成为一个虚拟面。经反射面3反射来的光线能够直接进入透镜部分4，通过透镜出光面42投射出去，形成照明光形。这样，就能够避免传统的车灯模组中光线需要经过车灯光学元件的出光面射出，再经过透镜的入光面射入所引起的光耗，提高车灯模组的光效。
作为本发明的车灯光学元件的一种具体实施方式，透镜入光面41与出光面2相重合，使得车灯光学元件的聚光器部分与透镜部分4之间形成平滑的过渡。这样形成的车灯光学元件的重心位于结构的几何中心，安装稳定性更高。
在本发明的车灯光学元件的一些实施例中，如图12-图17所示，车灯光 学元件透镜部分4的透镜入光面41大于聚光器部分的出光面2，即透镜入光面41的宽度和高度均大于出光面2的宽度和高度。出光面2一体连接在透镜入光面41的上部或者下部，使得出光面2仅成为一个虚拟面，而透镜入光面41的部分实体面得以保留。通过保留的部分透镜入光面41还能够射入光线，使得车灯光学元件的透镜部分还可以当普通透镜来使用，用于实现其它照明功能。这样，在使用本实施例的车灯光学元件组成车灯模组时，远光光源发出的光线可以由入光部1导入，经反射面3反射后通过透镜部分4的投射，形成远光照明光形；近光光源发出的光线可以经过近光初级光学元件汇聚后射向保留的部分透镜入光面41，经透镜部分4的投射，形成近光照明光形。这样还可以省略远近光一体车灯模组的透镜，简化远近光一体车灯模组的结构。
作为本发明的车灯光学元件的一种具体实施方式，如图18所示，在出光面2上设有截止线结构21。截止线结构21可以设置在出光面2的上侧边缘或者下侧边缘。设置在出光面2上的截止线结构21可以通过对通过出光面2射出的光线进行遮挡的方式形成明暗截止线，以形成带有明暗截止线的近光照明光形或远光照明光形，也可以通过对邻近的近光光源发出的光线进行遮挡的方式形成近光照明光形或远光照明光形的明暗截止线。这样，就可以省略车灯模组的截止线结构，简化车灯模组的结构。
在本发明的车灯模组中，使用了本发明任一实施例的车灯光学元件。
在本发明的车灯模组的一些实施例中，如图19、图20所示，包括光源5、车灯光学元件和透镜6。车灯光学元件包括入光部1、反射面3和出光面2，入光部1为设置在车灯光学元件右侧的聚光杯，每个聚光杯处设置一个光源5，光源5发出的光线经聚光杯导入后射向反射面3，经反射面3的反射后射向车灯光学元件前端的出光面2。出光面2的下侧边缘设置有截止线结构21，截止线结构21设置在透镜6的光轴61上，射向出光面2的光线经过截止线结构21的遮挡后射向透镜6，在透镜6的作用下投射出去，形成带有明暗截止 线的近光照明光形。
在本发明的车灯模组的一些实施例中，如图21、图22所示，包括近光光源51、近光反射镜7、远光光源52、车灯光学元件和透镜6。车灯光学元件包括入光部1、出光面2和反射面3，入光部1设置在车灯光学元件的右侧，出光面2设置在车灯光学元件的前端，反射面3斜向设置在车灯光学元件的左后侧，以将从入光部1射入的光线反射向出光面2。出光面2的上侧边缘处设置有截止线结构21，截止线结构21也可以从出光面21向后延伸至反射面3的边缘。出光面2上侧边缘处的截止线结构21设置在透镜6的光轴61附近，且位于透镜6的焦点附近。远光光源52设置在入光部1处，远光光源52发出的光线从入光部1射入，经过反射面3的反射后通过出光面2射向透镜6，在透镜6的作用下投射出去，形成具有明暗截止线的远光照明光形。近光光源51设置在近光反射镜7的第一焦点处，且位于透镜6的光轴61上，近光反射镜7的第二焦点与透镜6的焦点相重合。近光光源51发出的光线经过近光反射镜7的汇聚、截止线结构21的遮挡后射向透镜6，在透镜6的作用下投射出去，由于近光照明光形的照射角度相比远光照明光形的照射角度要大，因此，将车灯光学元件的前端向左右两侧延伸，使截止线结构21向左右两侧延长，以形成具有明暗截止线的近光照明光形。
本发明所提供的车灯光学元件，入光部1设置在车灯光学元件的侧方，减少了车灯光学元件后方或者下方的结构，因而能够减小车灯光学元件的前后尺寸和上下尺寸，使得车灯光学元件具有前后尺寸和上下尺寸较小，左右尺寸较大的扁平状结构。同时，使得车灯的光源和光源的散热器结构也能够随着入光部1设置在车灯光学元件的侧方，使得车灯的外形能够更好地适应当今的扁平状的车灯造型趋势。在本发明的车灯光学元件的优选实施例中，将入光部1分别设置在车灯光学元件左右两侧的结构，能够进一步缩短车灯光学元件的前后尺寸，适应车灯造型需要。聚光器部分与透镜部分4一体连接的结构，使得本发明的车灯光学元件同时实现了透镜的功能，且结构稳定 性更高，能够省略传统车灯中的透镜，使得车灯结构更加简单，结构的稳定性也更高。透镜部分4的透镜入光面41的一部分与出光面2一体连接的结构，使得车灯光学元件的透镜部分4还可以当普通透镜来使用，用于实现其它照明功能。在出光面2的边缘设置的截止线结构21，能够形成近光照明光形中的明暗截止线，省略传统车灯中的遮光板，简化车灯的结构。本发明的车灯模组，采用了本发明的车灯光学元件，前后尺寸和上下尺寸更小，左右尺寸更大，符合当今车灯的造型趋势。采用本发明的车灯光学元件优选实施例的车灯模组，也同时具有各优选实施例所具有的优点。
本发明的车灯，使用了本发明任一实施例的车灯模组，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。
