相关申请的交叉引用
本申请要求2020年05月26日提交的中国专利申请202010456521.3、2020年08月26日提交的PCT国际申请PCT/CN2020/111397的权益，该申请的内容通过引用被合并于本申请。
技术领域
本发明涉及车灯部件，具体地，涉及一种调光机构。此外，本发明还涉及一种车灯模组、车灯及车辆。
背景技术
车灯，尤其是前照灯，在使用前或在安装过程中需要将其光形调光校准到标准位置。所以，需要在车灯模组上设置调光机构使得照明单元的投射光形相对于标准位置光形(光形为投射在标准屏幕上的光形，对于前照灯近光或远光标准屏幕是车辆前方25m处的竖直屏幕)或者各照明单元的投射光形之间调整上下或者左右方向的角度，如图1至图3所示，其中，P0为标准位置光形，P1、P2、P3、P4为位置偏移光形，P1所示光形需要向下调光，P2所示光形需要向上调光，P3所示光形需要向右调光，P4所示光形需要向左调光，从而得到位于标准位置的光形P0。
如图4至图7所示，目前车灯模组中所使用的调光机构包括三个球头螺杆组件1，球头螺杆组件1包括球头螺杆101和球头螺母102，球头螺杆101的轴部设置螺纹，通过螺纹和支撑架或灯体连接，球头螺杆101前端设置球头，球头和设置有球窝的球头螺母102配合，球头螺母102和照明单元2固定连接。三个球头螺杆组件1中，其中一个球头螺杆组件1设置为相对支撑架或灯体固定不动的球头螺杆组件1，另外两个球头螺杆组件1设置为能够相对支撑架或灯体前后运动的可调的球头螺杆组件1，其中一个可调的球头螺杆组件1设置在固定的球头螺杆组件1的下方，通过转动该可调的球头螺杆组件1的球头螺杆101使球头螺杆101相对支撑架或灯体前后运动，使得照明单元2绕水平调光轴相对支撑架或灯体上下转动，实现上下方向的调光；另一个可调的球头螺杆组件1设置在固定的球头螺杆组件1的左侧或右侧，通过转动该可调的球头螺杆组件1的球头螺杆101相对支撑架或灯体前后移动，使得照明单元2绕竖直调光轴相对支撑架或灯体左右转动，实现左右方向的调光。其中，水平调光轴是由位于固定的球头螺杆组件1左侧或右侧的可调的球头螺杆组件1的球头球心和固定的球头螺杆组件1的球头球心连接形成的水平轴线，竖直调光轴是由位于固定的球头螺杆组件1下方的可调的球头螺杆组件1的球头球心和固定的球头螺杆组件1的球头球心连接形成的竖直轴线。
上述调光机构虽然能够实现上下和左右方向的调光，但是，还至少存在以下两点不足：第一、为了实现上下和左右调光，必须要将可调的球头螺杆组件1设置在固定的球头螺杆组件1侧面或者下方，使得调光机构整体的上下方向或左右方向的尺寸a(如图7所示)较大，适应不了上下尺寸或左右尺寸越来越小的车灯模组的空间布置要求；第二、如果车灯模组的上下方向或左右方向的尺寸较小，则会使得上下方向的两个球头螺杆组件1之间或左右方向的两个球头螺杆组件1之间的距离L较短，从而使得转动的动力臂较短，可调的球头螺杆组件1前后的少量移动就会使得照明单元2转动较大的角度，调光精度较低。

具体实施方式
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，本发明的保护范围并不局限于下述的具体实施方式。
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“连接”、“相连”应做广义理解，例如，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。
需要理解的是，如图4所示，基于车灯模组，“前”是指光线出射方向所指的方向，“后”是指与“前”相反的方向，“左”是指沿光线出射方向的左侧，“右”是指沿光线出射方向的右侧，“上”是指沿光线出射方向的上方，“下”是指沿光线出射方向的下方，术语为基于附图所示的方向或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
另外需要说明的是，调光机构的理论设计状态指的是本发明的调光机构的各部件之间的位置关系是以不需要上下、左右调光的照明单元为基准的。例如如图39所示的照明单元，其是以透镜5的光轴与车辆前后方向平行时的状态为基准设计各部件之间的位置关系，包括滑槽4与水平面或竖直平面的夹角，柱面槽6021的轴向中心线与两球头螺杆101的球头球心的几何关系等，在将车灯模组安装到车灯上后，由于制造公差或装配公差等原因，在进行调光时，上述位置关系都会改变。当然，该调光机构不仅适用于具有透镜5的照明单元2，还可以适用于其他照明单元，如具有反射式光学元件的照明单元等。
本发明的基本实施方式中，如图8至图18以及图26至图32所示，提供一种调光机构，该调光机构用于对照明单元2进行调光，包括固定球头连接件1a、第一可调球头连接件1b和第二可调球头连接件1c；固定球头连接件1a的一端与照明单元2连接，另一端与支撑架或灯体3连接；第一可调球头连接件1b一端与照明单元2连接，另一端支承在支撑架或灯体3上；照明单元2上设有滑槽4，第二可调球头连接件1c一端与滑槽4滑动连接，另一端支承在支撑架或灯体3上，第二可调球头连接件1c能够相对支撑架或灯体3前后运动，以能够带动滑槽4转动，并能够通过滑槽4的转动带动照明单元2转动而实现第二方向上的调光。
本发明的调光机构通过第二可调球头连接件1c能够实现第二方向上的调光，该第二方向优选为上下方向。本发明的调光机构可以应用于光形具有水平上边界的车灯模组与其他模组调光的情况，由于光形上边界呈水平状态，因此，只需在一个方向上(即上下方向)进行调光，另一个方向(即左右方向)可以不用进行调光。具体地，本发明的调光机构可以应用于辅助近光模组、角灯模组或Bending(弯道照明)模组等。具体光形效果如图40和图41所示，图40中显示为未调整前的主近光光形7和辅助近光光形8，主近光光形7和辅助近光光形8的光形上边界之间不重合，光线照明效果不佳。图41所示为调整后的主近光光形7和辅助近光光形8，两者的光形上边界重合，从而能够使得照明效果更好。
在这里需要说明的是，第一方向和第二方向优选为相互垂直的两个方向，以能够更准确地调整光形的位置。 以下以第一方向和第二方向相互垂直为例进行进一步解释说明。
具体地，第一可调球头连接件1b和第二可调球头连接件1c可以是球头螺杆组件1，也可以是具有球头结构的杆件。固定球头连接件1a可以是任意能够实现支撑架或灯体3与照明单元2固定连接且不会影响固定球头连接件1a和照明单元2之间转动的球头连接件，也可以是如第一可调球头连接件1b和第二可调球头连接件1c一样的球头螺杆组件1或者具有球头结构的杆件。球头螺杆组件1包括球头螺杆101和球头螺母102。具有球头结构的杆件即将球头螺杆组件1的球头螺杆101更换为没有螺纹的杆件。当第一可调球头连接件1b和第二可调球头连接件1c是球头螺杆组件1时，支撑架或灯体3上设有适于球头螺杆101穿过的两个孔，且这两个孔内部均设有与球头螺杆101的外螺纹适配的内螺纹。工作时，旋转球头螺杆101使得球头螺杆组件1前后运动，从而带动照明单元2的转动。当第一可调球头连接件1b和第二可调球头连接件1c为具有球头结构的杆件时，支撑架或灯体3上设有适于第一可调球头连接件1b和第二可调球头连接件1c的杆件插入的两个孔，且该孔的大小设置为不会影响第一可调球头连接件1b或第二可调球头连接件1c在其内部前后方向滑动。工作时，控制球头结构的杆件的前后滑动，从而带动照明单元2的转动。当然，第一可调球头连接件1b和第二可调球头连接件1c还可以是具有球头结构的伸缩件，即将球头螺杆101更换为伸缩杆，伸缩杆可与支撑架或灯体3固定连接，通过伸缩杆的伸缩带动照明单元2的转动。优选地，第一可调球头连接件1b和第二可调球头连接件1c为球头螺杆组件1，可以进行微小调整，使其精度更高。
上述基本实施方式提供的调光机构工作时，以固定球头连接件1a、第一可调球头连接件1b和第二可调球头连接件1c均为球头螺杆组件1为例，当第一方向上需要调光时，固定球头连接件1a中的球头螺杆101的球头及与其配合的球头螺母102形成转动副结构，第一可调球头连接件1b中球头螺杆101的球头及与其配合的球头螺母102形成转动副结构，通过第一可调球头连接件1b的前后运动使得照明单元2以过固定球头连接件1a的球头球心且与第一方向垂直的直线为第一转轴Ⅰ转动，以使照明单元2的光形沿第一方向移动，如图37所示。第二方向上调光时，固定球头连接件1a中球头螺杆101的球头及与其配合的球头螺母102形成转动副结构，第一可调球头连接件1b中球头螺杆101的球头及与其配合的球头螺母102形成转动副结构，第二可调球头连接件1c中球头螺杆101的球头及与其配合的球头螺母102形成转动副结构，通过第二可调球头连接件1c的前后运动使得滑槽4以固定球头连接件1a的球头球心以及第一可调球头连接件1b的球头球心的连线为第二转轴Ⅱ转动，从而带动照明单元2转动，进而使照明单元2的光形沿第二方向移动，如图38所示。
具体地，固定球头连接件1a的球头球心和第一可调球头连接件1b的球头球心的连线即上述第二转轴Ⅱ沿第一方向延伸，第二可调球头连接件1c设于固定球头连接件1a和第一可调球头连接件1b的后方，以能够减小照明单元2在第二方向上的尺寸a＇以及增大第二可调球头连接件1c的球头球心与第二转轴Ⅱ之间的距离L＇，实现照明单元2在第二方向上的小型化以及调光精度。
上述基本实施方式提供的调光机构，通过第一可调球头连接件1b的前后运动带动照明单元2转动以实现第一方向上的调光，通过第二可调球头连接件1c的前后运动带动滑槽4和照明单元2的转动而实现第二方向上的调光。该调光机构不需要将第二可调球头连接件1c沿第二方向设置在固定球头连接件1a的一侧，能够减小照明单元2在第二方向上的尺寸a＇，实现照明单元2在第二方向上的小型化。而且，第二可调球头连接件1c设置在固定球头连接件1a和第一可调球头连接件1b的后方，可增大第二可调球头连接件1c的球头球心与第二转轴Ⅱ之间的距离L＇，即照明单元2在第二方向上转动的动力臂增大，如图12所示，相比现有技术，第二可调球头 连接件1c运动相同的距离，本发明提供的调光机构会使得照明单元2在第二方向上的转动量更小，则第二方向的调光的精度更高。
优选地，固定球头连接件1a和第一可调球头连接件1b均与支撑架或灯体3固定连接，使得固定球头连接件1a和第一可调球头连接件1b不会相对支撑架或灯体前后移动，从而使得本发明的调光机构仅具有在第二方向上的调光功能。该方案适用于光形具有水平上边界的车灯模组的调光，第一可调球头连接件1b固定在支撑架或灯体3上即可，结构简单，制作成本也较低。
为了能够增加第一方向上的调光精度，在本发明的一个具体实施方式中，第一可调球头连接件1b设置在照明单元2上远离固定球头连接件1a的一端。通过将第一可调球头连接件1b设置在照明单元2上远离固定球头连接件1a的一端，可以增加第一方向上的调光时照明单元2转动的动力臂，使得第一可调球头连接件1b运动相同的距离时照明单元2转动的角度更小，从而提高调光的精度。
在本发明的一个具体实施方式中，第一方向为上下方向，第二方向为左右方向；固定球头连接件1a的球头球心、第一可调球头连接件1b的球头球心以及第二可调球头连接件1c的球头球心置于同一竖直平面内，能够减小在上下方向上调光时左右方向上产生的分量。该具体实施方式能够减小照明单元2在左右方向上的尺寸，实现车灯模组在左右方向上的小型化。
为了能够通过第二可调球头连接件1c的前后运动带动滑槽4的转动以实现照明单元2左右方向上的调光，在本发明的一个具体实施方式中，滑槽4与竖直平面之间形成的夹角可以为0°-90°，优选15°-60°。具体地，可以是本领域的技术人员根据实际使用和安装情况具体设定。同样的，滑槽4与竖直平面间的夹角角度也是指在理论设计状态下，滑槽4与竖直平面间的夹角角度，当进行上下、左右调光时，滑槽4摆动，该夹角角度也会变化。
在本发明的一个具体实施方式中，第一方向为左右方向，第二方向为上下方向；如图11所示，固定球头连接件1a的球心、第一可调球头连接件1b的球心以及第二可调球头连接件1c的球心置于同一水平面内，能够减小在左右方向上调光时上下方向上产生的分量。该具体实施方式能够减小照明单元2在上下方向上的尺寸，实现车灯模组在上下方向上的小型化。
为了能够通过第二可调球头连接件1c的前后运动带动滑槽4的转动以实现照明单元2上下方向上的调光，在本发明的一个具体实施方式中，滑槽4与水平面之间形成的夹角可以为0°-90°，优选15°-60°。具体地，可以是本领域的技术人员根据实际使用和安装情况具体设定。同样的，滑槽4与水平面间的夹角角度也是指在理论设计状态下，滑槽4与水平面间的夹角角度，当进行上下、左右调光时，滑槽4摆动，该夹角角度也会变化。
在本发明的一个具体实施方式中，如图13、图17和图18所示，固定球头连接件1a、第一可调球头连接件1b和第二可调球头连接件1c均为球头螺杆组件1，球头螺杆组件1包括球头螺杆101和球头螺母102，滑槽4上设有能够与滑槽4滑动连接的滑块6，滑块6包括与滑槽4滑动连接的滑块底座601和固定于滑块底座601上的固定部602，第二可调球头连接件1c的球头螺母102与固定部602卡接。具体地，固定部602可以是环状结构，第二可调球头连接件1c的球头螺母102上设有卡槽，第二可调球头连接件1c的球头螺母102通过卡槽卡设在固定部602上，防止第二可调球头连接件1c在固定部602上的相对滑动，固定部602的外侧设有适于在滑槽4内滑动的滑块底座601。
在第二可调球头连接件1c前后运动的过程中，第二可调球头连接件1c会带动固定部602运动，从而带动 滑块6前后运动并在滑槽4内滑动，由于滑槽4相比固定球头连接件1a的球心、第一可调球头连接件1b的球心以及第二可调球头连接件1c的球心所在的平面倾斜设置，滑块6的前后运动会使滑槽4以及照明单元2会以固定球头连接件1a的球心以及第一可调球头连接件1b的球心的连接线为第二转轴Ⅱ转动，从而实现第二方向上的调光。如：当第二方向为左右方向时，则照明单元2绕第二转轴Ⅱ转动，从而实现左右方向上的调光；如图9所示，当第二方向为上下方向时，则照明单元2绕第二转轴Ⅱ转动，从而实现上下方向上的调光。
第一方向上调光时，转动第一可调球头连接件1b，第一可调球头连接件1b相对支撑架或灯体3前后运动，带动照明单元2绕过固定球头连接件1a的球心且与第一方向垂直的直线沿第一方向转动，实现第一方向上的调光。此时，照明单元2相对支撑架或灯体3沿第一方向转动，由于滑槽4一体设置于照明单元2，第二可调球头连接件1c以及滑块6相对支撑架或灯体3固定不动，使得滑槽4相对滑块6沿第一方向转动，因此，滑槽4和滑块6之间在第一方向上存在间隙以使两者可以相对运动，例如，如图14、图15所示，第一方向为左右方向时，滑槽4和滑块6之间在左右两侧均设有间隙；再例如，第一方向为上下方向时，滑槽4和滑块6之间在上下两侧均设有间隙。
在本发明的另一个具体实施方式中，如图26至图30所示，固定球头连接件1a、第一可调球头连接件1b和第二可调球头连接件1c均为球头螺杆组件1，球头螺杆组件1包括球头螺杆101和球头螺母102，第二可调球头连接件1c的球头螺母102上设有滑块6，滑块6设在滑槽4内。优选地，滑块6一体设置于球头螺母102。
具体地，此处的滑槽4可以是两个杆状结构形成的适于滑块6卡入的空隙，滑块6远离球头螺母102的一端设有开口，能够使该滑块6具有更好地弹性，以方便将滑块6更好地插入滑槽4中，且能够更好地固定在滑槽4中，使得在未进行调光操作时，滑块6和滑槽的相对位置固定，以保持照明单元2的投射光形的稳定性。
以上两种具体实施方式中，由于滑槽4和滑块6是斜面接触配合，滑槽4相对滑块6在第一方向上相对移动时，也会产生第二方向上的移动，即滑块6相对滑槽4会产生微量的前后运动，使得照明单元2在第二方向上也有微量转动。因此，调光时，优先进行第一方向上的调光，再进行第二方向上的调光，这是因为，在进行第一方向上的调光时，照明单元2在第二方向上也会有微量转动，若先进行第二方向上的调光，照明单元2的投射光形在第二方向上达到标准位置，再进行第一方向上的调光后，其在第二方向上因照明单元2的微量转动又偏离了标准位置，降低了第二方向上的调光准确度。同时，在进行第一方向上的调光时，第二可调球头连接件1c的球头螺杆101和球头螺母102之间会产生应力。
在进行第一方向上的调光时，为了减小照明单元2在第二方向上的微量转动以及第二可调球头连接件1c的球头螺杆101和球头螺母102之间的应力，作为本发明的又一个具体实施方式，如图31和图32所示，固定球头连接件1a和第一可调球头连接件1b为球头螺杆组件1，球头螺杆组件1包括球头螺杆101和球头螺母102；第二可调球头连接件1c设置为球头螺杆101，滑槽4上设有能够与滑槽4滑动连接的滑块6，滑块6包括与滑槽4滑动连接的滑块底座601和固定于滑块底座601上的固定部602，固定部602上设有能够与第二可调球头连接件1c的球头配合的柱面槽6021，第二可调球头连接件1c的球头能够沿着柱面槽6021相对滑动。在进行第一方向上的调光时，照明单元2相对支撑架或灯体3沿第一方向转动，由于滑槽4一体设置于照明单元2上，而第二可调球头连接件1c的球头与滑块6通过柱面槽6021滑动连接，第二可调球头连接件1c相对支撑架或灯体3固定不动，使得滑块6可以随滑槽4一起沿第一方向转动，而第二可调球头连接件1c的球头不动，因此，滑块6相对滑槽4不会产生微量的前后运动或者只是极其微量的前后运动，从而减小了照明单元2在第二方向上的微量 转动，同时，由于第二可调球头连接件1c仅通过球头螺杆101的球头和柱面槽6021的配合与滑块6滑动连接，减小了部件之间的应力。优选地，第二可调球头连接件1c的球头球心设于柱面槽6021的轴向中心线6022上。
在第二可调球头连接件1c前后运动的过程中，第二可调球头连接件1c会带动滑块6前后运动并在滑槽4内滑动，为了使滑槽4适应滑块6的滑动，由于滑槽4相比固定球头连接件1a的球心、第一可调球头连接件1b的球心以及第二可调球头连接件1c的球心所在的平面倾斜设置，滑块6的前后运动会使滑槽4以及照明单元2以固定球头连接件1a的球心以及第一可调球头连接件1b的球心的连线为第二转轴Ⅱ转动，从而实现第二方向上的调光。如：当第二方向为左右方向时，则照明单元2绕第二转轴Ⅱ转动，从而实现左右方向上的调光；当第二方向为上下方向时，则照明单元2绕第二转轴Ⅱ转动，从而实现上下方向上的调光。
在本发明的一个相对优选地实施例中，以第一方向为左右方向为例，如图8至图18所示，调光机构包括固定球头连接件1a、第一可调球头连接件1b和第二可调球头连接件1c，第一可调球头连接件1b与固定球头连接件1a设置在照明单元2的左右两个端部，且两者的球头球心的连线为一条水平线；固定球头连接件1a的一端与照明单元2连接，另一端与支撑架或灯体3连接；第一可调球头连接件1b一端与照明单元2连接，另一端支承在支撑架或灯体3上，第一可调球头连接件1b能够相对支撑架或灯体3前后运动；照明单元2上设有滑槽4，滑槽4上设有能够与滑槽4滑动连接的滑块6，滑块6包括与滑槽4滑动连接的滑块底座601和固定于滑块底座601上的固定部602，第二可调球头连接件1c的一端与固定部602卡接，滑块6与滑槽4之间在左右两侧均设有间隙，第二可调球头连接件1c的另一端支承在支撑架或灯体3上，第二可调球头连接件1c能够相对支撑架或灯体3前后运动，固定球头连接件1a的球心、第一可调球头连接件1b的球心以及第二可调球头连接件1c的球心置于同一水平面内，滑槽4与该水平面之间形成有夹角。
在上述优选实施例提供的调光机构工作时，第一可调球头连接件1b、第二可调球头连接件1c、固定球头连接件1a和支撑架或灯体3通过螺纹进行连接，调光时，支撑架或灯体3作为固定件。左右方向上调光时，转动第一可调球头连接件1b，第一可调球头连接件1b相对支撑架或灯体3前后运动，带动照明单元2绕第一转轴Ⅰ转动，实现左右方向上的调光。此时，照明单元2相对支撑架或灯体3左右转动，由于滑槽4一体设置于照明单元2，第二可调球头连接件1c以及滑块6相对支撑架或灯体3固定不动，使得滑槽4相对滑块6左右转动，因此，滑槽4和滑块6之间在左右方向上存在间隙以使两者可以相对运动，同时，由于滑槽4和滑块6是斜面接触配合，滑槽4相对滑块6会产生左右移动，也会产生上下方向的移动，使得照明单元2在上下方向上也有微量转动。上下方向上调光时，转动第二可调球头连接件1c，第二可调球头连接件1c相对支撑架或灯体3前后运动，滑块6在向上倾斜的滑槽4内前后移动，使得滑槽4绕第二转轴Ⅱ转动，从而带动照明单元2绕第二转轴Ⅱ转动，实现上下方向上的调光。第二可调球头连接件1c向前运动，照明单元2向上转动，第二可调球头连接件1c向后运动，照明单元2向下转动。
在本发明的另一个相对优选地实施例中，以第一方向为左右方向为例，如图26至图30所示，调光机构包括固定球头连接件1a、第一可调球头连接件1b和第二可调球头连接件1c，第一可调球头连接件1b与固定球头连接件1a设置在照明单元2的左右两个端部，且两者的球头球心的连线为一条水平线；固定球头连接件1a的一端与照明单元2连接，另一端与支撑架或灯体3连接；第一可调球头连接件1b一端与照明单元2连接，另一端支承在支撑架或灯体3上，第一可调球头连接件1b能够相对支撑架或灯体3前后运动；照明单元2上设有滑槽4，固定球头连接件1a、第一可调球头连接件1b和第二可调球头连接件1c均为球头螺杆组件1，球头螺杆组件 1包括球头螺杆101和球头螺母102，第二可调球头连接件1c的球头螺母102上设有滑块6，滑块6设在滑槽4内，第二可调球头连接件1c支承在支撑架或灯体3上，其能够相对支撑架或灯体3前后运动，固定球头连接件1a的球心、第一可调球头连接件1b的球心以及第二可调球头连接件1c的球心置于同一水平面内，滑槽4与水平面之间形成有夹角。
在本发明的又一个相对优选地实施例中，如图31和图32所示，以第一方向为左右方向为例，调光机构包括固定球头连接件1a、第一可调球头连接件1b和第二可调球头连接件1c，第一可调球头连接件1b和固定球头连接件1a设置在照明单元2的左右两个端部，且两者的球头球心的连线为一条水平线；固定球头连接件1a的一端与照明单元2连接，另一端与支撑架或灯体3连接；第一可调球头连接件1b一端与照明单元2连接，另一端支承在支撑架或灯体3上，第一可调球头连接件1b能够相对支撑架或灯体3前后运动；固定球头连接件1a和第一可调球头连接件1b均为球头螺杆组件1，球头螺杆组件1包括球头螺杆101和球头螺母102，第二可调球头连接件1c仅包括球头螺杆101，照明单元2上设有滑槽4，滑槽4上设有能够与滑槽4滑动连接的滑块6，滑块6包括与滑槽4滑动连接的滑块底座601和固定于滑块底座601上的固定部602，固定部602上设有能够与第二可调球头连接件1c的球头配合的柱面槽6021，第二可调球头连接件1c的球头能够沿着柱面槽6021相对滑动。第二可调球头连接件1c支承在支撑架或灯体3上，其能够相对支撑架或灯体3前后运动，固定球头连接件1a的球心、第一可调球头连接件1b的球心以及第二可调球头连接件1c的球心置于同一水平面内，滑槽4与该水平面之间形成有夹角。左右方向上调光时，则是转动第一可调球头连接件1b，，第一可调球头连接件1b相对支撑架或灯体3前后运动，带动照明单元2绕第一转轴I转动，此时，照明单元2相对支撑架或灯体3左右转动，实现左右方向上的调光。上下方向上调光时，转动第二可调球头连接件1c，第二可调球头连接件1c相对支撑架或灯体3前后运动，滑块6在向上倾斜的滑槽4内前后移动，使得滑槽4绕第二转轴Ⅱ转动，从而带动照明单元2绕第二转轴Ⅱ转动，实现上下方向上的调光。第二可调球头连接件1c向前运动，照明单元2向上转动，第二可调球头连接件1c向后运动，照明单元2向下转动。
上述三个优选实施例提供的调光机构，通过第一可调球头连接件1b的前后运动带动照明单元2转动以实现左右方向的调光，通过第二可调球头连接件1c的前后运动带动滑槽4上下转动以使照明单元2上下转动而实现上下方向的调光。该调光机构不需要将第二可调球头连接件1c沿上下方向设置在固定球头连接件1a的一侧，能够减小照明单元2在上下方向上的尺寸a＇，实现车灯模组在上下方向上的小型化。而且，第二可调球头连接件1c设置在固定球头连接件1a和第一可调球头连接件1b的正后方，可增大第二可调球头连接件1c的球头球心与第二转轴Ⅱ之间的距离L＇，即照明单元2上下方向转动的动力臂增大，如图12所示，相比现有技术，第二可调球头连接件1c运动相同的距离，本发明提供的调光机构会使得照明单元2在上下方向上的转动量更小，从而使得上下方向上的调光精度更高。同时，将第一可调球头连接件1b设置在远离固定球头连接件1a的一侧，能够增加第一可调球头连接件1b球头球心到第一转轴Ⅰ之间的距离，增加照明单元2左右方向上转动的动力臂，从而提高左右方向上的调光精度。
作为本发明的一个具体结构形式，照明单元2上设有滑槽4，第二可调球头连接件1c的一端通过滑块6与滑槽4滑动连接。
具体地，如图19至图25、图33至图36所示，滑块6包括与滑槽4滑动连接的滑块底座601以及固定于滑块底座601上的固定部602，滑块底座601的两侧形成有滑动部6011，滑块底座601通过该滑动部6011与滑 槽4滑动连接，以能够使滑块6沿着滑槽4滑动。在这里，滑槽4具有导向作用，滑块6的两侧滑动部6011插接入滑槽4内，能够引导滑块6沿着滑槽4的方向滑动。而图19至图25和图33至图36所示的滑块6具有两种结构形式的固定部602，固定部602能够与第二可调球头连接件1c的球头活动连接：第一种结构形式，固定部602形成为环状结构，第二可调球头连接件1c包括球头螺杆101和球头螺母102，其球头螺母102上形成有卡槽，卡槽能够卡入该环状结构内，以使固定部602与第二可调球头连接件1c卡接，第二可调球头连接件1c的球头球心设于环状结构的轴向中心线6022上，固定部602形成为圆环形，第二可调球头连接件1c的球头螺母102上形成有卡槽，该卡槽能够卡入该呈圆环形的固定部602内，以实现第二可调球头连接件1c与固定部602的固定连接，固定部602的四周可以形成有环形圆台，既能够对球头螺母102上用于形成卡槽的卡爪进行一定的限位，也能够对卡槽形成保护。另外，固定部602形成为圆环形，但是该固定部602的两侧形成有凸台6023，凸台6023沿固定部602的轴向延伸，两侧凸台6023的上部形成为开口结构。以上两种结构的固定部602根据实际安装需要选择。第二种结构形式，固定部602形成有柱面槽6021，第二可调球头连接件1c设置为球头螺杆101，第二可调球头连接件1c的球头安装配合在柱面槽6021内且能够沿柱面槽6021滑动。在这里需要说明的是，在该调光机构的理论设计状态下，第二可调球头连接件1c的球头球心位于滑块6的竖直中心面上，滑块6、滑槽4与照明单元2的竖直中心面均重合，柱面槽6021的轴向中心线6022垂直于经过固定球头连接件1a的球头球心与第二可调球头连接件1c的球头球心的竖直平面，其中柱面槽6021的内表面为第二可调球头连接件1c的球头与竖直平面的截线沿轴向中心线6022拉伸形成。此时，在左右调光时，由于滑块6是沿以固定球头连接件1a的球头球心为圆心、以固定球头连接件1a的球头球心与第二可调球头连接件1c的球头球心的连线为半径形成的弧线段的轨迹转动，而轴向中心线6022为直线，第二可调球头连接件1c的球头只能沿直线相对柱面槽6021滑动，使得第二可调球头连接件1c的球头和柱面槽6021之间仍具有一定的应力；或者柱面槽6021的轴向中心线6022形成为以固定球头连接件1a的球头球心为圆心、以固定球头连接件1a的球头球心与第二可调球头连接件1c的球头球心的连线为半径的弧线段，其中柱面槽6021的内表面为第二可调球头连接件1c的球头与竖直平面的截线沿轴向中心线6022拉伸形成，竖直平面为经过固定球头连接件1a的球头球心与第二可调球头连接件1c的球头球心的竖直平面。此时，在左右调光时，滑块6是沿上述弧线段的轨迹转动，第二可调球头连接件1c的球头与柱面槽6021的相对滑动也是沿上述弧线段，使得第二可调球头连接件1c的球头和柱面槽6021之间基本不存在应力，有利于延长零件使用寿命，但考虑零件的制造成本等原因，优选轴向中心线6022为直线的柱面槽6021。柱面槽6021与第二可调球头连接件1c的球头紧密配合，既能够保证第二可调球头连接件1c的球头在柱面槽6021内转动，也能够保证其在柱面槽6021内的滑动。
另外，从图示中还能够看出，固定部602上与第二可调球头连接件1c的卡槽贴靠的平面与滑动部6011的上平面或下平面形成有夹角，该夹角角度与上述滑槽4与水平面间的夹角角度之和为90°，也可以理解为固定部602与滑块底座601之间形成有夹角，该夹角角度与上述滑槽4与水平面间的夹角角度之和为90°，以保证第二可调球头连接件1c水平延伸。
可选地，如图29和图30所示，滑块6形成为连接在球头螺母102上的滑动杆，滑块6能够滑动连接于滑槽4内。因此，滑槽4的结构除了图19至图25、图33至图36中所示的结构外，还可以是图29和图30所示的结构形式，此时滑块6在滑槽4内滑动，也能够引导第二可调球头连接件1c沿着滑槽4滑动。当然，滑块6与滑槽4的配合结构还可以采用其他结构形式，其目的是使滑块6能够沿着滑槽4滑动，从而能够使得第二可调球 头连接件1c沿着滑槽4方向前后移动，均属于本发明的保护范围。
作为本发明的另一个具体结构形式，如图19至图25、图33至图36中所示，滑块底座601远离固定部602的一端端面上设有或一体形成有弹性支承结构6012，弹性支承结构6012抵靠滑槽4的底面并能够形成反向作用力以能够使滑块底座601紧贴滑槽4并能够沿滑槽4滑动。
具体地，弹性支承结构6012为成对的弧形弹性薄片，弧形弹性薄片沿着滑槽4方向延伸。
更具体地，弹性支承结构6012的一侧边沿与滑块底座601的下部边沿连接。可以理解的是，该弹性支承结构6012的一侧边与滑块底座601的下部边沿连接，另一边则与滑块底座601的下表面之间形成空隙，同时该弹性支承结构6012为向下弯曲的曲面结构。当滑动部6011插入滑槽4内，在该弹性支承结构6012的弹性作用力下使得滑动部6011紧贴滑槽4，同时也不会影响滑动部6011在滑槽4内的滑动。在这里需要说明的是，这里所指的“上”、“下”仅是以图21至图25、图33至图36中零件所示的现有位置，并不能够代表零件实际安装后所指的位置。
此外，本发明的实施例还提供一种车灯模组，该车灯模组包括上述各实施例的调光机构和照明单元2，为了能够有效利用车灯模组的内部空间，照明单元2包括散热件201，滑槽4一体式地或者可拆卸地设置在散热件201上。优选为一体式连接，可以减少安装步骤，降低安装难度。
而且，本发明的实施例提供一种车灯，该车灯包括上述各实施例的车灯模组。
本发明的实施例还提供一种车辆，该车辆包括上述实施例的车灯。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于上述实施方式中的具体细节，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，这些简单变型均属于本发明的保护范围。
另外需要说明的是，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，可以通过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。
此外，本发明的各种不同的实施方式之间也可以进行任意组合，只要其不违背本发明的思想，其同样应当视为本发明所公开的内容。
