Description

初级光学元件、初级光学组件、光学组件、车灯照明装置及车辆 技术领域
本发明涉及车灯，具体地，涉及一种初级光学元件。此外，本发明还涉及包含该初级光学元件的初级光学组件、包含该初级光学组件的光学组件，以及包含该光学组件的车灯照明装置和车辆。
背景技术
在车灯技术领域，车灯照明装置一般用于汽车前照灯照明，具有光源、初级光学元件和透镜或相当结构的零件形成的次级出光元件。初级光学元件一般都是由透明材质的玻璃、硅胶或塑料制造而成的，能够将光源射出的光线进行初级配光(比如聚焦、准直等)，因此，初级光学元件对车灯照明效果的好坏起到了很大的作用，而初级光学元件的定位和安装可靠性对车灯光形的精度和车灯照明效果影响很大。同时，设置在初级光学元件上的任何一个部件都会对光线的初级配光产生影响，过多的安装结构和定位结构会对初级光学元件的配光效果产生或多或少的影响。
现有技术中，车灯的初级光学元件在入光部通常设置有聚光结构，以对光源发出的光线进行汇聚和准直，提高光线的利用率，但是其结构比较复杂，制作工艺要求较高，加工难度较大，且制作工序较为繁琐。对于近光照明模式中，有些光线并不要求很高的照度，满足光形均匀性要求即可，不需要初级光学元件中的入光部结构太复杂。基于上述原因，车灯中开始逐渐使用导光条，导光条呈柱形，其一端设置光源、另一端与出光部连接，以能够在近光照明模式下直接对光源发出的光线进行汇聚、传播。
但是，目前已有的含有导光条的初级光学元件仍存在光学效率和光学效果较差的缺陷。此外，随着车灯造型的小型化和扁平化，市场对小型车灯照明装置的需求越来越多，这对车灯光学元件等光学零部件之间的位置精度要求也越来越高，现有技术提供的初级光学元件及其他定位结构和限制结构难以有效保证初级光学元件的安装效果，尤其缺乏能够应用在小型化车灯照明装置中的光学元件安装结构，从而使得车灯照明装置的照明效果不理想、光学效率较差。

本发明第一方面提供一种初级光学元件，参见图1至图10所示，包括初级光学元件主体，初级光学元件主体包括由后向前设置的导光部101和融合出光部102，融合出光部102的前端面设置为出光面1021，导光部101包括沿左右方向依次排列的多个导光柱，融合出光部102沿上下方向的厚度大于导光部101沿上下方向的厚度，融合出光部102能够将多个导光柱传输至该融合出光部102的光线进行融合后经出光面1021出射。
本发明中，初级光学元件1可以选用硅胶、PC、PMMA等透明材料制成，优选为采用硅胶制成，使得初级光学元件1具有耐温高、透过率高的效果。
本发明所提供的初级光学元件1中，参见图9，导光柱的后端面形成为入光面1013，在应用于车灯照明装置时，每个入光面1013的后端分别设置有相应的光源(即下文的近光光源7)，近光光源7发出的光线经相应的入光面1013入射至导光柱内，并经该导光柱传输至融合出光部102内，由于融合出光部102的厚度增高，各导光柱传输至融合出光部102的光线不仅能够在该融合出光部102内融合使得传输至出光面1021的光线分布较为均匀，而且能够使得从出光面1021出射的光线更加扩散，有利于近光光形的上边界下方的光形柔化，从而使得初级光学元件1的光学效率高且形成的近光光形效果佳。
在本发明初级光学元件1的第一种优选实施例中，参见图1至图7，多个导光柱包括两个侧边导光柱1011和至少一个中间导光柱1012，至少一个中间导光柱1012沿左右方向依次排列在两个侧边导光柱1011之间，侧边导光柱1011的外侧面设置为从该侧边导光柱1011的后端先沿直线向前延伸、再沿曲线向外侧弯曲延伸至融合出光部102的后侧。侧边导光柱1011的外侧面具体指的是该侧边导光柱1011上远离中间导光柱1012的侧面，例如位于左侧的侧边导光柱1011的外侧面即为该侧边导光柱1011的左侧面。多个导光柱设置为沿左右方向依次排列，使得初级光学元件1能够满足车灯造型的小型化和扁平化的结构设计要求，同时侧边导光柱1011的外侧面设置为从后端先沿直线向前延伸、再沿曲线向外侧弯曲延伸至融合出光部102的后侧，使得侧边导光柱1011的外侧轮廓向两侧逐渐弯曲，能够增加近光光形两侧的照明范围，改善光形效果。
在本发明中间导光柱1012的一些优选实施例中，中间导光柱1012设置为左侧面与右侧面之间的距离由后向前逐渐增大，以能够使得该中间导光柱1012与其相邻的导光柱之间形成导光柱间隙，同时也能够使得入射至中间导光柱 1012的入光面1013的光线尽可能多的在其内部发生全反射并向前传输。此时，侧边导光柱1011的内侧面也可以设置为由后向前倾斜设置，以使得相邻的中间导光柱1012之间、侧边导光柱1011与该侧边导光柱1011相邻的中间导光柱1012之间均形成楔形的导光柱间隙，以防止各导光柱之间窜光，降低光学效率。
优选情况下，中间导光柱1012的左侧面与右侧面形成的夹角大小为2°-4°，侧边导光柱1011与该侧边导光柱1011相邻的中间导光柱1012之间的间隙夹角θ的大小，即侧边导光柱1011与其相邻的中间导光柱1012之间的导光柱间隙的角度为5°-10°，以提高入射至侧边导光柱1011和中间导光柱1012的光线在相应的导光柱内进行全反射的效率，进一步提高光线在初级光学元件1中的光学效率。
在本发明初级光学元件1的第二种优选实施例中，出光面1021设置为前凸曲面，使得出射的光线更汇聚，以提高初级光学元件1的光学效率。
优选情况下，参见图1、图2、图21和图22，出光面1021的底部形成有截止线结构，截止线结构包括中心截止线结构1022和位于中心截止线结构1022两侧的截止线外侧延伸结构1026，截止线外侧延伸结构1026与中心截止线结构1022顺滑连接，以能够使得出光面1021出射的光线经下文中的次级光学元件3(例如透镜)投射形成的光形上具有明暗截止线b，可以根据光形的要求进行相应的结构设计。具体地，出光面1021的底部形成有截止线结构时，中心截止线结构1022用于形成近光光形中部的主近光光形的上边界，即光形的明暗截止线b的中间一部分，其对应形成的上边界为两侧有段差且通过斜线连接的截止线形状。
进一步优选地，融合出光部102的前端底部设置有一个凹坑，以作为50L暗区形成结构1023，减少射至50L暗区的光线，控制50L暗区的亮度，以使得近光光形符合法规要求。
本发明中，导光部101可以设置为在融合出光部102的后端沿上下方向的中部与融合出光部102连接；也可以设置为导光部101的底面与融合出光部102底面持平，以能够在出光面1021的底部形成有截止线结构时，保证所形成的近光光形上明暗截止线b的形状与位置。
在出光面1021的底部形成有截止线结构时，为了改善明暗截止线b处的色散现象，提高驾驶员的视觉感受，本发明中出光面1021的一些优选实施例中，参见图5，出光面1021包括主出光面1024和位于主出光面1024下侧的次出光面1025，次出光面1025设置为由上至下逐渐向后下方倾斜，截止线结构设置在次出光面1025上。此时，次出光面1025能够使得经截止线结构的光线向前上方倾斜进入次级光学元件3，可以尽量避免这部分光线从次级光学元件3的下半部分射出，使得形成的明暗截止线b的颜色得以改善，提高驾驶员的视觉感受。优选情况下，主出光面1024与次出光面1025之间设有过渡面，过渡面优选设置为圆弧面，以能够将主出光面1024与次出光面1025顺滑连接。
作为本发明中初级光学元件1的一种相对优选的具体实施结构，初级光学元件1包括初级光学元件主体，初级光学元件主体包括由后向前设置的导光部101和融合出光部102，融合出光部102沿上下方向的厚度大于导光部101沿上下方向的厚度，融合出光部102的前端面设置为出光面1021，导光部101包括沿左右方向依次排列的三个导光柱，三个导光柱为两个侧边导光柱1011和一个中间导光柱1012，侧边导光柱1011和中间导光柱1012的后端面形成为入光面1013，侧边导光柱1011的外侧面设置为从该侧边导光柱1011的后端先沿直线向前延伸、再沿曲线向外侧弯曲延伸至融合出光部102的后侧，中间导光柱1012的左侧面与右侧面之间的距离由后向前逐渐增大，且形成大小为2°-4°的夹角，侧边导光柱1011与中间导光柱1012之间的导光柱间隙的角度为5°-10°，出光面1021设置为前凸曲面，出光面1021包括主出光面1024和位于主出光面1024下侧的次出光面1025，次出光面1025设置为由上至下逐渐向后下方倾斜，次出光面1025的底部设置有截止线结构，截止线结构包括中心截止线结构1022和位于中心截止线结构1022两侧的截止线外侧延伸结构1026，截止线外侧延伸结构1026与中心截止线结构1022顺滑连接，融合出光部102的前端底部设置有50L暗区形成结构1023。
上述初级光学元件1所对应的近光光源7发出的光线，经相应的入光面1013入射至侧边导光柱1011和中间导光柱1012内，并经该导光柱传输至融合出光部102内，融合出光部102使得各导光柱传输至融合出光部102的光线在该融合出光部102内进行融合后，从出光面1021出射，同时经截止线结构的作用，使得出光面1021出射的光线形成明暗截止线，50L暗区形成结构1023能够有效控制50L暗区的亮度，以使得形成的近光光形符合法规要求。
本发明的初级光学元件1在安装于车灯照明装置中时，可以采用常规的安装方式，与车灯照明装置内的其它部件连接固定，优选为将初级光学元件1安装在初级光学元件支架2上，此时，初级光学元件1与初级光学元件支架2形 成为初级光学组件。

在车灯使用过程中，通常设置有次级光学元件3，太阳光照射至次级光学元件3会在车灯内部聚焦形成高温，而车灯内部的零件多为塑料材质，在高温下会出现熔化现象，不仅会损坏车灯，还存在一定的安全隐患。因此，在车灯内易聚焦的区域可以设置防太阳光聚焦板207，以减少传导至易熔化的零部件上的热量，降低车灯损坏风险，提高安全性。作为本发明中初级光学元件支架2的第二种优选实施例，初级光学元件支架2上设置有防太阳光聚焦板207，此时，防太阳光聚焦板207优选采用金属材料制成，例如采用ADC材料制成，不仅轻质经济，而且导热性能好。
进一步优选地，参见图12，支撑板202的底部设置有加强结构2022，以能够增强支撑板202的结构强度，从而提高对融合出光部102的支撑稳定性。
作为本发明中初级光学元件支架2的一种相对优选的具体实施结构，初级光学元件支架2适用于包括导光部101和融合出光部102的初级光学元件1，导光部101具有多个导光柱，初级光学元件支架2包括用于插接初级光学元件主体的初级光学元件主体容纳腔201和位于初级光学元件主体容纳腔201内的支撑板202，初级光学元件主体容纳腔201的后端设置有多个截面周长由前向后逐渐减小的正棱台形通孔203，每个正棱台形通孔203的后端开口设置为能够对导光柱进行限位的导光柱限位孔2031，正棱台形通孔203的数量大于或等于导光柱的数量，初级光学元件支架2上设置有防太阳光聚焦板207，初级光学元件主体容纳腔201的外侧设置有卡块2011，初级光学元件主体容纳腔201的前端形成有初级光学元件后移限位面2012，支撑板202的底部设置有加强结构2022。
上述初级光学元件支架2能够将相应的初级光学元件主体安装在该初级光学元件主体容纳腔201内，使得初级光学元件1前端的融合出光部102支撑在支撑板202上，导光柱的后端***导光柱限位孔2031进行限位，使得初级光学元件1的安装结构稳定性好、位置精度高，提高光学效率、改善车灯的照明效果。
本发明第三方面提供一种初级光学组件，包括上述任意一项技术方案所述的初级光学元件1和用于安装初级光学元件1的初级光学元件支架2。在利用初级光学元件支架2对初级光学元件1进行安装时，初级光学元件支架2可以采用现有技术中的安装支架，为了进一步提高初级光学元件1安装使用时的结构稳定性和形成的光形稳定性，初级光学元件支架2优选为采用本发明中上述任意一项技术方案所述的初级光学元件支架2。
为了便于初级光学元件1与初级光学元件支架2的安装连接，作为本发明中初级光学组件的第一种优选实施例，参见图16至图30，结合图8至图10，初级光学元件1还包括与初级光学元件主体连接的初级光学元件安装部103，融合出光部102的左右侧面和顶面均与初级光学元件安装部103连接、底面与初级光学元件安装部103之间形成有插板孔1031，结合图11至图15，初级光学元件主体容纳腔201内设置有支撑板202，支撑板202能够插接在插板孔1031内，从而将融合出光部102支撑在支撑板202上。在初级光学元件主体从初级光学元件支架2前侧***初级光学元件主体容纳腔201时，相应地，支撑板202插接在插板孔1031内，融合出光部102支撑在支撑板202上，使得初级光学元件1与初级光学元件支架2的安装连接更加稳固，从而提高初级光学元件1的光学稳定性。
可以理解的是，本发明的初级光学组件中，上述初级光学元件1与初级光学元件支架2的安装连接方式，可以适用于多种结构的初级光学元件1和/或初级光学元件支架2，并不局限于仅为本发明中所述的结构形式。具体地，初级光学组件可以包括初级光学元件1和用于安装初级光学元件1的初级光学元件支架2，初级光学元件1包括初级光学元件主体和与初级光学元件主体连接的初级光学元件安装部103，初级光学元件主体包括由后向前设置的导光部101和出光部，出光部的前端面设置为出光面1021，出光部的左右侧面和顶面均与初级光学元件安装部103连接、底面与初级光学元件安装部103之间形成有插板孔1031；初级光学元件支架2包括用于容纳初级光学元件主体的初级光学元件主体容纳腔201，初级光学元件主体容纳腔201内设置有支撑板202，以能够在初级光学元件主体安装在初级光学元件主体容纳腔201的状态下，使得支撑板202插接在插板孔1031内，出光部支撑在支撑板202上。此时，初级光学元件1与初级光学元件支架2的连接能够实现两者稳固的安装固定，提高初级光学元件1的光学稳定性。因此，下述的插板孔1031、支撑板202、初级光学元件主体容纳腔201和初级光学元件安装部103的优选结构形式也适用于该初级光学组件。
本发明中，参见图17和图18，插板孔1031的下端设置为支撑板接触面，其与支撑板202的底面接触，且支撑板接触面的结构设计为与支撑板202的底面相适应。例如，支撑板202设计为中间低、两边高的结构，相应地，支撑板接触面也设计为中间低、两边高的结构，以使得支撑板202与插板孔1031插接结构更加稳定。
优选情况下，初级光学元件主体容纳腔201的外侧设置有卡块2011，初级光学元件安装部103上设置有与卡块2011相匹配的卡槽1032。通过卡块2011与卡槽1032的配合，以限制初级光学元件1相对初级光学元件支架2向前移动，不易产生相对于初级光学元件支架2的位移。相应地，参见图26和图27，初级光学元件主体容纳腔201的前端形成有初级光学元件后移限位面2012，与初级光学元件安装部103的内端面抵接，以用于限制初级光学元件1相对初级光学元件支架2向后移动。卡槽1032具体可以设置为分布在初级光学元件安装部103的各个侧壁上，并在初级光学元件主体容纳腔201的外侧设置相应的卡块2011，以提高初级光学元件1与初级光学元件支架2安装后的结构稳定性。
在上述初级光学元件1的第二种优选实施例的基础上，参见图21和图22，出光面1021的底部形成有中心截止线结构1022和位于中心截止线结构1022两侧的截止线外侧延伸结构1026，作为本发明中初级光学组件的第二种优选实施例，支撑板202的前端面设置为内凹曲面，且该支撑板202顶面的前端两侧分别设置有外侧延伸截止线结构2021，外侧延伸截止线结构2021能够与中心截止线结构1022衔接以形成组合截止线结构，代替中心截止线结构1022与截止线外侧延伸结构1026形成的截止线结构。由于初级光学元件1的出光面1021为前凸曲面，通常情况下，中心截止线结构1022两边向外延伸形成为截止线外侧延伸结构1026，中心截止线结构1022与截止线外侧延伸结构1026相配合使得近光光形上的明暗截止线b易出现如图19所示的两侧翘起、不平整的现象。因此，需要将中心截止线结构1022的外侧设置为由前向后内凹的曲线才能使得明暗截止线b的两侧比较平整，本发明通过在初级光学元件支架2上用于支撑初级光学元件1的融合出光部102的支撑板202的前端设置内凹曲线形状的外侧延伸截止线结构2021，即将支撑板202的前端面的顶面两端作为外侧延伸截止线结构2021，与中心截止线结构1022衔接形成组合截止线结构，以形成如图20所示的两侧较为平整的明暗截止线b。
优选情况下，支撑板202的顶面上位于截止线外侧延伸结构1026和外侧延伸截止线结构2021之间的区域设置有镀铝层，以能够提高照射在该区域内的光线的反射率，使得照射在该区域内的光线被反射后继续向前传播，提高光学效率。
作为本发明中初级光学组件的一种相对优选的具体实施结构，包括初级光学元件1和初级光学元件支架2，初级光学元件1包括初级光学元件主体和与初级光学元件主体连接的初级光学元件安装部103，初级光学元件主体包括由后向 前设置的导光部101和融合出光部102，融合出光部102沿上下方向的厚度大于导光部101沿上下方向的厚度，融合出光部102的前端面设置为出光面1021，导光部101包括沿左右方向依次排列的三个导光柱，三个导光柱为两个侧边导光柱1011和一个中间导光柱1012，侧边导光柱1011和中间导光柱1012的后端面形成为入光面1013，侧边导光柱1011的外侧面设置为从该侧边导光柱1011的后端先沿直线向前延伸、再沿曲线向外侧弯曲延伸至融合出光部102的后侧，中间导光柱1012的左侧面与右侧面之间的距离由后向前逐渐增大，且形成大小为2°-4°的夹角，侧边导光柱1011与中间导光柱1012之间的导光柱间隙的角度为5°-10°，出光面1021设置为前凸曲面，出光面1021包括主出光面1024和位于主出光面1024下侧的次出光面1025，次出光面1025设置为由上至下逐渐向后下方倾斜，次出光面1025的底部设置有截止线结构，截止线结构包括中心截止线结构1022和位于中心截止线结构1022两侧的截止线外侧延伸结构1026，截止线外侧延伸结构1026与中心截止线结构1022顺滑连接，融合出光部102的前端底部设置有50L暗区形成结构1023，融合出光部102的左右侧面和顶面均与初级光学元件安装部103连接、底面与初级光学元件安装部103之间形成有插板孔1031，插板孔1031的下端设置为与支撑板202的底面结构相匹配的支撑板接触面，初级光学元件安装部103上设置有与卡块2011相匹配的卡槽1032；

上述的初级光学组件安装过程为：将初级光学元件支架2从初级光学元件1的后侧与初级光学元件1插接，使得初级光学元件主体容纳腔201从初级光学元件1的后侧插接于初级光学元件安装部103的内腔，初级光学元件主体安装在该初级光学元件主体容纳腔201内，支撑板202插接在插板孔1031内，使得支撑板202的底面与支撑板接触面贴合、顶面与融合出光部102的底面贴合，以使得外侧延伸截止线结构2021与中心截止线结构1022具有中心截止线结构和外侧延伸截止线结构相接处a，以形成组合截止线结构，同时将卡块2011卡接入对应的卡槽1032内，初级光学元件后移限位面2012与初级光学元件安装部103的内端面抵接，侧边导光柱1011与中间导光柱1012的后端分别从对应的正棱台形通孔203的前端***并限定在导光柱限位孔2031上，以形成初级光学组件。
在上述初级光学元件1、初级光学元件支架2及两者形成的初级光学组件的基础上，可将初级光学元件1以初级光学组件的形式安装于车灯照明装置中。优选情况下，根据车灯造型的小型化和扁平化要求和市场对小型车灯照明装置的需求，本发明第四方面提供了一种光学组件，参见图31至图41，以将初级光学元件1、初级光学元件支架2、次级光学元件3和次级光学元件支架4安装为一体，使得车灯照明装置的零部件之间结构更加紧凑、位置精度更高。
作为本发明中光学组件的第一种优选实施例，参见图31至图33，次级光学元件支架4上设置有用于容纳初级光学组件的初级光学组件容纳腔401，次级光学元件3安装在初级光学组件容纳腔401的前端，初级光学元件1与初级光学组件容纳腔401上设置有定位限制结构，以能够在初级光学组件置于初级光学组件容纳腔401内时限制该初级光学组件的自由度，从而提高初级光学组件与次级光学元件支架4之间连接的结构稳定性和相对位置精度，进而提高初级光学元件1和次级光学元件3之间的相对位置精度，以提高形成的近光光形效果。
可以理解的是，本发明的光学组件中，上述初级光学组件和次级光学元件支架4的安装连接方式，可以适用于多种结构的初级光学组件和/或次级光学元件支架4，并不局限于仅为本发明中所述的结构形式，其中，初级光学组件由初级光学元件支架2与初级光学元件1插接形成即可。具体地，光学组件可以包括初级光学元件1、次级光学元件3、用于安装初级光学元件1的初级光学元件支架2和用于安装次级光学元件3的次级光学元件支架4，初级光学元件1包括初级光学元件主体，初级光学元件主体包括由后向前设置的导光部101和出光部，出光部的前端面设置为出光面1021；初级光学元件支架2包括初级光学元件主体容纳腔201，初级光学元件支架2能够与初级光学元件1插接，以使得初级光学元件主体安装在该初级光学元件主体容纳腔201内形成为初级光学组件；次级光学元件支架4上设置有用于容纳初级光学组件的初级光学组件容纳腔401，次级光学元件3安装在初级光学组件容纳腔401的前端，初级光学元 件1与初级光学组件容纳腔401上设置有定位限制结构，以能够在初级光学组件置于初级光学组件容纳腔401内时限制该初级光学组件的自由度。此时，定位限制结构能够提高初级光学组件与次级光学元件支架4之间连接的结构稳定性和相对位置精度，进而提高初级光学元件1和次级光学元件3之间的相对位置精度，以提高形成的近光光形效果。因此，下述的定位限制结构的优选结构形式也适用于该光学组件。
本发明中，定位限制结构可以是设置在初级光学元件1与初级光学组件容纳腔401上的任意一种相互配合进行连接限位的结构。优选情况下，定位限制结构包括位于初级光学组件容纳腔401上的限位腔402和位于初级光学元件1上的限位块1033，限位腔402与限位块1033相匹配。初级光学组件置于初级光学组件容纳腔401内时，限位块1033卡接在相应的限位腔402内。由于初级光学元件安装部103的材料一般为硅胶，限位块1033优选设置为具有一定厚度的方块状，使得限位块1033与限位腔402的定位更加准确，若限位块1033的厚度较薄，容易产生形变的现象，不利于其定位安装。限位块1033的长、宽、厚均优选设置为大于或等于2mm，示例性地，可设置为长(上下方向)约7.5mm、宽(左右方向)约5mm、厚(前后方向)约4mm。
具体地，参见图8，限位块1033位于初级光学元件1的前端的左右两侧，以使得对初级光学组件的限位作用更加平衡，初级光学组件与次级光学元件支架4限位安装精度更高。在初级光学元件1包括初级光学元件安装部103时，限位块1033设置为位于初级光学元件安装部103的前端的左右两侧。

进一步具体地，定位限制结构还可以包括以下结构：参见图8和图32，初级光学元件1的前端设置有位于限位块1033上侧和/或下侧的初级光学元件前移限位面1036，初级光学组件容纳腔401的后端设置有与初级光学元件前移限位面1036相匹配的容纳腔前移限位面4011，以使得初级光学组件安装在初级光学组件容纳腔401内时，初级光学元件前移限位面1036与容纳腔前移限位面4011抵接，以限制初级光学组件向前移动的自由度。
作为本发明中光学组件的第二种优选实施例，参见图34至图37，次级光学元件支架4的后端设置有导向销404，初级光学元件支架2上设置有与导向销404匹配的导向孔206，以便于在将初级光学组件与次级光学元件支架4安装时进行快速导向和预定位。优选情况下，导向孔206和导向销404安装后两者之间不贴合，具有一定的间隙，从而导向孔206和导向销404相配合只起导向和预定位作用，不起精确定位作用。
作为本发明中光学组件的一种相对优选的具体实施结构，包括初级光学元件1、用于安装初级光学元件1的初级光学元件支架2、次级光学元件3和用于安装次级光学元件3的次级光学元件支架4；

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。
