优选地，参考图13，该万向连接结构600采用球窝610与万向球头620配合的形式。
根据本发明的一个第一示例，至少一个发光单元P2包括远光单元P2a和远近光单元P2b，支承支架P1包括与其对应的第一支承部100a和第二支承部100b。

具体地，远光单元P2a和远近光单元P2b分别各自设置至少三个 球窝610，用于匹配相应的万向球头620，以分别连接至第一支承部100a和第二支承部100b。

继续参考附图，图9a、9b、9c分别示意出了根据本发明的一个实施例的一种对准机构的沿水平方向转动的示意图。其中OH示意出了近光单元P2a水平面的正向轴线，O’H’示意出了远光单元P2b水平面的正向轴线。轴线OH和O’H‘分别表示相应的发光单元P2的正面朝向。通过轴线OH和O’H’的转动，能够更加清晰的看出支承支架P1带动两个发光单元P2沿着水平方向转动的情况。
并且，由于第二转动部500位于支承支架P1上，因此，当支承支架P1沿着水平方向转动时，带动第二转动部500围绕其与第二推动部P4之间的万向球头520同时沿着水平方向转动。其中，，本领域技术人员应可根据实际情况和需求来确定第一推动部P3和第二推 动部P4各自的最大调节距离。
例如，可基于实际需求，设定所述第一推动部P3的最大调节距离为4-6mm。，第二推动部P4的最大调节距离为4-6mm。又例如，设定所述第二推动部P3向前调节的最大调节距离为4-5mm，向后调节的最大调节距离为5-6mm，等。
并且，本领域技术人员应可根据实际情况和需求来确定支承支架P1沿着水平方向和沿着垂直方向各自的最大调节角度。
例如，设定所述支承支架P1沿水平方向上的最大转动角度为3-5度，所述支承支架P1沿着垂直方向的最大转动角度为3-5度，等。
优选地，所述支承支架P1的所述第一转动部300的转动轴线EE’的位置，可基于所述第一推动部P3的最大调节距离，以及所述支承支架P1的最大转动角度来确定。
例如，假定第一推动部P3的调节距离为s1，支承支架P1沿着水平方向的最大转动角度为α度，则第一转动轴线EE′与第一推动部P3的距离为s1/(tanα)。
更优选地，基于转动轴线EE’的位置，可进一步确定第一转动部300的位置。
接着，参考图17a、17b以及17c。图17a、17b、17c示意出了根据本发明的一个实施例的一种汽车前灯的沿垂直方向转动的示意图。
其中，轴线OV为灯组单元P2在垂直方向的朝向轴线，其用于指示灯组单元P2的正面朝向的方向。通过轴线OV的转动，能够更加清晰的看出当第二转动部500前后运动时，直接带动灯组单元P2在垂直方向转动的情况。

根据本发明的又一个优选实施例，参考图10-图16。根据本发明所述的支承支架P1还包括第二转动部500；所述第二转动部用于使得所述第一支承部100和所述第二支承部200沿垂直方向同步转动。
其中，所述第二转动部500与所述近光单元P2a和所述远光单元P2b分别采用万向连接结构600来连接。
优选地，根据本发明的支承支架P1还具有第一滑动部700，所述第二转动部500具有与所述第一活动部700匹配的第二活动部510，以使得所述第二转动部500可通过所述第一活动部700和所述第二活动部 510的配合，沿着所述支承支架P1的前后方向滑动。

其中，所述第二转动部500沿着所述滑槽结构700前后滑动时，同时推拉所述至少一个发光单元P2围绕各自的所述万向连接结构600沿垂直方向向下或向上倾斜。

根据本发明的一种汽车前灯的对准方法，所述汽车前灯采用如本发明所述的对准机构；其中，所述对准方法包括步骤Step1和Step2。
在Step1中，调节第一推动部P3，使第一推动部P3推拉所述支承支架P1，使得支承支架P1围绕其第一转动部300的转动轴线EE’转动，亦即所述至少一个支承部(100)围绕所述转动轴线同步转动，进而使得所述发光单元(P2)沿水平方向同步转动。
在Step2中，调节第二推动部(P4)，使得第二推动部(P4)沿着所述支承支架(P1)的滑槽结构(700)前后滑动，同时推拉所述至少一个发光单元(P2)围绕各自的所述万向连接结构(600)在垂直方向同步向下或向上倾斜。
本领域技术人员应可理解，步骤Step1和Step2没有先后顺序，可以先执行步骤Step1再执行步骤Step2，也可以先执行步骤Step2再执行步骤Step1；或者，同时执行步骤Step1和Step2。
参考图19，图19示意出了本方案的一个实施例的灯组单元的重心距离的改变。
其中，图19上部示意出了一种现有技术的情况，对于一个发光单元，现有的对准机构的重心位于G1，其垂直调节机构为VA1，转向 点位于PS1，其重心G1距离与转向点的距离为D1；图19的下部示意出了根据本发明的一个实施例的情况，对于一个发光单元，对准机构的重心位于G2，垂直调节机构为VA2(亦即第二推动部P4)，与第二推动部P4对应的转向点为PS2，其重心G2与转向轴PS2的距离为D2。本领域技术人员可以直观看到，虽然两个方案重心位置未变，但本方案中重心与转向轴的距离D2明显小于D1，因此转向点所承受的力矩更小。并且，根据本发明的方案，对于每个发光单元，都可具有两个转向点，其结构更加稳定。
显然，由于支承支架通过其自身的第一转动部连接至罩壳上，从而使得其重心与转动点更加靠近，使得灯组单元重心距离与转动点之间的距离形成的力矩极大的缩小，从而降低了对于支承支架所需承受的重量的要求，亦即，降低了对于支承支架的材料强度的需求，因此能够极大的降低材料的成本。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化涵括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。此外，显然“包括”一词不排除其他单元或步骤，单数不排除复数。系统权利要求中陈述的多个单元或装置也可以由一个单元或装置通过软件或者硬件来实现。第一，第二等词语用来表示名称，而并不表示任何特定的顺序。
