此外，在本发明的描述中，除非另有说明，“多个”的含义是两个或两个以上。
如图1至图13所示，本发明车灯光学元件总成的一种实施例。
参见图1至图3，本实施例的车灯光学元件总成包括初级光学元件组件1和次级光学元件组件2。初级光学元件组件1包括初级光学元件11和第一支架12，第一支架12支撑初级光学元件11。次级光学元件组件2包括次级光学元件21和第二支架22，第二支架22支撑次级光学元件21。第一支架12与第二支架22配合连接，使初级光学元件11与次级光学元件21相对固定。由此，通过第一支架12与第二支架22的配合连接，将初级光学元件11与次级光学元件21装配成一整体结构而直接确定了两者的相对位置，实现了初级光学元件11与次级光学元件21之间的直接定位。参见图11和图12，将本实施例的车灯光学元件总成安装到线路板3及散热器4上时，由于初级光学元件11与次级光学元件21之间存在固定的装配定位关系，不会因与线路板3及散热器4的装配而使两者之间产生定位误差，因此能够保证初级光学元件11与次级光学元件21的定位精度和安装可靠性，从而保证车灯光形的准确性 和功能稳定性。
本实施例的车灯光学元件总成安装在线路板3上时，初级光学元件11位于线路板3与次次级光学元件21之间，线路板3上光源发出的光线依次经过初级光学元件11和次级光学元件21后射出，形成车灯照明光形。本文中，为便于描述，定义线路板3、初级光学元件11和次级光学元件21的排布方向为从后至前，即线路板3位于初级光学元件11的后方，次级光学元件21位于初级光学元件11的前方，在水平面内与前后方向垂直的为左右方向，在竖直平面内与前后方向垂直的为上下方向。
参见图4至图8，本实施例中，优选地，初级光学元件组件1中的第一支架12包括支撑架121和限位件122，限位件122固设于初级光学元件11，支撑架121设有限位槽123，限位件122与限位槽123配合连接，并且，限位件122与支撑架121相对固定。由此，通过限位件122与支撑架121的配合连接，使得初级光学元件11与支撑架121相对固定，实现了将初级光学元件11定位支撑在第一支架12上，即，限位件122和支撑架121装配在一起构成支撑初级光学元件11的第一支架12。在一种较佳的实施方式中，支撑架121的上表面部分下沉形成限位槽123，使得限位槽123的底面123a朝上且为水平面，限位件122的下表面122a为水平面，限位件122置于限位槽123中，且限位件122的下表面122a与限位槽123的底面123a接触配合。
为增加限位件122与支撑架121之间装配定位的准确性，优选地，限位件122设有第一定位孔124，限位槽123内设有第一定位销125，第一定位销125与第一定位孔124插接配合。在将限位件122安装到支撑架121上时，通过第一定位销125与第一定位孔124的插接配合，可以限定限位件122与支撑架121的相对位置，对限位件122进行准确定位，从而实现初级光学元件11与第一支架12之间的准确定位。
进一步，为确保初级光学元件11与第一支架12之间定位和安装的可靠性，优选地，限位件122可以设有两个，两个限位件122分别相对设于所述初级光学元件11的左、右两侧，支撑架121上设有两个分别与两个限位件122配合连接的限位槽123，两个限位槽123分别设于支撑架121的左、右两侧，两个限位槽123内均设有第一定位销125，分别与两个限位件122上的第一定位孔124插接配合。由此，初级光学元件11通过左、右两个限位件122共同支撑定位在支撑架121上，且两个限位件122分别通过第一定位孔124与第一定位销125的插接配合实现与支撑架121之间的定位，能够有效增加初级光学元件11与第一支架12之间定位的精确性和安装的可靠性。
进一步，为便于装配、防止产生过定位，优选地，两个限位件122其中一个限位件122上的第一定位孔124为圆孔，且另一个限位件122上的第一定位孔124为腰形孔，两个限位槽123内第一定位销125的断面形状均为圆形，一个第一定位销125与为圆孔的第一定位孔124配合插接，另一个第一定位销125与为腰形孔的第一定位孔124配合插接。通过第一定位销125与为腰形孔的第一定位孔124的配合插接，可以补偿限位件122与支撑架121的加工误差，使两者的装配更容易。
本实施例中，优选地，次级光学元件组件2中的次级光学元件21与第二支架22可以为一体成型的整体件。
参见图1、图2、图9和图10，本实施例中，优选地，次级光学元件组件2中的第二支架22设有插槽221，第一支架12与插槽221插接配合，且第一支架12具有与插槽221内侧的表面相接触的定位面。通过第一支架12的定位面与插槽221内侧表面的接触配合，可以限定第一支架12与第二支架22的相对位置，使得第一支架12与第二支架22相对固定，实现第一支架12与第二支架22之间的装配定位，具有安装方便、定位可靠的优点。
本实施例中，与初级光学元件组件1中初级光学元件21的左、右两侧分别设有一个限位件122相匹配地，第二支架22的左、右两侧分别设有一个插槽221，两个插槽221之间为供初级光学元件组件1***的装配空间。两个限位件122分别装配到支撑架121上对应的限位槽123内后，与支撑架121构成整体***相应的插槽221中，从而实现第一支架12与第二支架22的装配，初级光学元件11则位于两个插槽221之间的装配空间内。
为便于第一支架12与第二支架22的装配，并使得次级光学元件21位于初级光学元件11的前方，优选地，次级光学元件21设于第二支架22的前端，插槽221贯通第二支架22的后端面22a且从后向前延伸。由此，使得第一支架12能够从插槽221的后端***插槽221内并沿图3中箭头所示方向向前进入插槽221内，直至第一支架12的定位面与插槽221内侧的表面接触配合到位，支撑在第一支架12上表面的初级光学元件11则位于次级光学元件21的后方。
为保证第一支架12的定位面与插槽221内侧表面的接触配合能够有效限定第一支架12与第二支架22的相对位置，优选地，插槽221内侧的表面形成有前表面221a、上表面221b和下表面221c，第一支架12的定位面包括位于第一支架12前端面的前定位面、位于第一支架12上表面的上定位面以及位于第一支架12下表面的下定位面，其中，前定位面与插槽221内侧的前表面221a相接触，以限制第一支架12相对第二支架22向前移动；上定位面与插槽 221内侧的上表面221b相接触，以限制第一支架12相对第二支架22向上移动；下定位面与插槽221内侧的下表面221c相接触，以限制第一支架12相对第二支架22向下移动。本实施例中，支撑架121位于限位槽123正前方的前端面121a构成第一支架12的前定位面；限位件122装配到支撑架121上的限位槽123内后，限位件122的上表面122b高于支撑架121的上表面，因此限位件122的上表面122b构成第一支架12的上定位面；支撑架121的下表面121b构成第一支架12的下定位面。参见图2，在一种较佳的实施方式中，插槽221内侧的上表面221b有部分凹陷而不与限位件122的上表面122b接触配合，插槽221内侧的下表面221c有部分凹陷而不与支撑架121的下表面121b接触配合，由此可以减小插槽221内侧的上表面221b与限位件122的上表面122b的接触面积、插槽221内侧的下表面221c与支撑架121的下表面121b的接触面积，形成小面积接触定位，小面积的接触面的加工精度更容易保证，可使得第一支架12的定位面与插槽221内侧的表面之间更好地干涉，从而使定位更精准。
进一步，本实施例中，优选地，插槽221沿左右方向贯通第二支架22，第一支架12的左、右两侧分别设有一个卡合部126，两个卡合部126相对的内侧面126a分别与第二支架22的左侧面22b、右侧面22c相接触，以限制第一支架12相对第二支架22左右移动。在一种较佳的实施方式中，两个卡合部126分别设于支撑架121的左、右两侧侧面上且均向前延伸至支撑架121前端面121a的前方，装配后，支撑架121的前端面121a与插槽221内侧的前表面221a相接触，两个卡合部126则位于第二支架22的外侧，且两个卡合部126的内侧面126a分别与第二支架22的左侧面22b、右侧面22c位于插槽221前方的区域相接触配合。为使第一支架12的卡合部126能够通过插槽221的后端到达插槽221前方外侧，第二支架22的后端设有前后贯通第一支架22的通槽222，通槽222的开口朝向插槽221并在插槽221的外侧与插槽221的后端相连通，当支撑架121和限位件122***插槽221内时，位于支撑架121侧面的卡合部126从通槽222通过并到达插槽221前方外侧。
参见图5、图10和图12，本实施例中，优选地，第一支架12的后端具有用于与线路板3的表面3a相对接的后定位面，第二支架22的后端面22a上设有用于与线路板3的表面3a相对接的突出部223。在将本实施例的车灯光学元件总成安装在线路板3上时，通过第一支架12的后定位面与线路板3的表面3a接触配合、第二支架22后端的突出部223与线路板3的表面3a对接配合，可以限制第一支架12相对第二支架22向后移动，并将车灯光学元件总成定位在线路板3的表面3a上。本实施例中，支撑架121的后端面121c构成第一支架12的后定位面。优选地，可以在第二支架22的后端面22a上的左、右两侧分别设置一个突出部 223。通过在第二支架22的后端面22a上设置与线路板3的表面3a相对接的突出部223，避免了第二支架22的后端面22a整体与线路板3的表面3a相接触，减小了第二支架22后端与线路板3表面3a的接触面积，形成小面积接触定位，小面积的接触面的加工精度更容易保证，可使得突出部223与线路板3的表面3a之间更好地干涉，从而使定位更精准。
为增加车灯光学元件总成与线路板3之间装配定位的准确性，参见图12和图13，优选地，第一支架12的后端延伸有第二定位销127，线路板3设有第二定位孔31，第二定位销127用于与第二定位孔31插接配合。在将本实施例的车灯光学元件总成安装在线路板3上时，通过第二定位销127与第二定位孔31的插接配合，可以限定车灯光学元件总成与线路板3的相对位置，对车灯光学元件总成进行准确定位，从而实现车灯光学元件总成与线路板3之间的准确定位。为确保车灯光学元件总成与线路板3之间定位和安装的可靠性，优选地，第一支架12的后端可以延伸有两个第二定位销127，两个第二定位销127分别位于第一支架12的后端的左、右两侧。相应地，线路板3设有两个第二定位孔31，分别与两个第二定位销127插接配合。
进一步，为便于装配、防止产生过定位，优选地，线路板3上的两个第二定位孔31其中一个为圆孔，且另一个为腰形孔，第一支架12后端的两个第二定位销127的断面形状均为圆形，一个第二定位销127与为圆孔的第二定位孔31配合插接，另一个第二定位销127与为腰形孔的第二定位孔31配合插接。通过第二定位销127与为腰形孔的第二定位孔31的配合插接，可以补偿第一支架12与线路板3的加工误差，使两者的装配更容易。
本实施例的车灯光学元件总成装配完成后，需要将装配完成的车灯光学元件总成安装到线路板3和散热器4上。参见图11、图12和图13，在安装本实施例的车灯光学元件总成时，可以先将线路板3预定位在散热器4上，优选地，散热器4设有至少一个定位凸起41，线路板3上设有供定位凸起41***的定位槽32，通过定位凸起41与定位槽32的插接配合，实现线路板3与散热器4的预定位。由于本实施例的车灯光学元件总成中初级光学元件11与次级光学元件21的相对位置已确定，因此线路板3与散热器4的定位不需要特别高的定位精度，使得车灯光学元件总成在线路板3与散热器4上的安装过程十分简单便捷。线路板3与散热器4预定位完成后，将车灯光学元件总成定位在线路板3的表面3a上，具体为，将第一支架12后端的两个第二定位销127分别与线路板3上的两个第二定位孔31插接配合，并使第一支架12的后定位面与线路板3的表面3a接触配合、第二支架22后端的突出部223与线路板3的表面3a对接配合。然后将车灯光学元件总成与线路板3、散热器4固定连接即可完成车 灯光学元件总成的安装。
为实现本实施例的车灯光学元件总成与线路板3、散热器4之间的固定连接，参见图1，本实施例的车灯光学元件总成在第二支架22的后端开设有第一螺纹孔224，参见图11和图12，线路板3上开设有第二螺纹孔33，第一螺纹孔224和第二螺纹孔33相对接且供螺纹连接件5穿过，散热器4上开设有与螺纹连接件5配合连接的第三螺纹孔(图中未示出)，由此，通过螺纹连接件5依次连接第一螺纹孔224、第二螺纹孔33和第三螺纹孔，可以实现本实施例的车灯光学元件总成与线路板3、散热器4之间的紧固连接，从而完成本实施例的车灯光学元件总成的安装。
综上，本实施例的车灯光学元件总成，通过第一支架12与第二支架22的配合连接，将初级光学元件11与次级光学元件21装配成一整体结构而直接确定了两者的相对位置，实现了初级光学元件11与次级光学元件21之间的直接定位。并且，通过第一支架12的前定位面(支撑架121的前端面121a)与第二支架22插槽221内侧的前表面221a相接触限制了第一支架12相对第二支架22向前移动，通过第一支架12的上定位面(限位件122的上表面122b)与插槽221内侧的上表面221b相接触限制了第一支架12相对第二支架22向上移动，通过第一支架12的下定位面(支撑架121的下表面121b)与插槽221内侧的下表面221c相接触限制了第一支架12相对第二支架22向下移动，通过第一支架12上两个卡合部126相对的内侧面126a分别与第二支架22的左侧面22b、右侧面22c相接触限制了第一支架12相对第二支架22左右移动，通过第一支架12的后定位面(支撑架121的后端面121c)与线路板3的表面3a接触配合、第二支架22后端的突出部223与线路板3的表面3a对接配合限制了第一支架12相对第二支架22向后移动，由此，实现了第一支架12与第二支架22在前后、上下、左右方向上的相对固定，保证了第一支架12与第二支架22全方位定位精度以及安装稳定性，即保证了初级光学元件11与次级光学元件21的定位精度以及安装稳固性，使得车灯光学元件总成在长时间使用后仍能保持初级光学元件11与次级光学元件21的相对位置不变，从而保证车灯光形的准确性和稳定性。此外，将初级光学元件组件1和次级光学元件组件2装配成一整体结构、确定了初级光学元件11与次级光学元件21的相对位置后，再将该整体结构安装到线路板3和散热器4上，可降低线路板3与散热器4的定位精度要求，使得安装过程更为简单便捷。
