如图14所示，作为上述实施例的改进技术方案，在至少一个实施例中，所述凹形外壳5在靠近外周区域的外表面上具有半径大于2.5mm的周边外圆角55，所述周边外圆角55沿所述凹形外壳5的外壳顶部51周向延伸；所述周边外圆角55呈凸起状，即从凹形外壳外侧观察时，所述周边外周角55的最顶端不仅超出外壳侧部52的侧部外表面52a而且超出外壳顶部51的顶部外表面51a。该周边外圆角55与外壳顶部51和外壳侧部52是一体模塑成型的，所述周边外圆角55的设计，当电致变色镜元件组装在后视镜组件中时，视觉上可以部分地隐藏后视镜组件后端的塑料件，使后视镜组件整体更加美观。
当本领域技术人员采用如上述实施例所详细描述的电致变色镜元件结构并将其安 装至后视镜外壳内，形成一个完整的具有电致变色功能的后视镜时，还需要清楚知道所描述的电致变色镜元件的各组成部分所采用的可实施材料和电致变色镜元件的电极引出方式，同时为了描述清楚且避免关于电致变色镜各组成部件材料和电极引出方式的讨论过于冗繁，发明人在以下部分进行详细描述：

作为一个可替代的实施方案，所述第二导电夹92的一端延伸到第三表面21b上的外周区域的部分位置，并非直接与第二表面11b上的透明导电层7接触形成电连通，而是进一步地是通过设置导电银浆使第二导电夹92和透明导电层7建立了电连接关系，所述导电银浆设置在电极引出通道与透明导电层连通的位置，即第一边缘表面11c、第二边缘表面21c和密封件3外表面的连通位置，更进一步地，透明导电层7从第二表面11b延伸至第一边缘表面11c，以增大第二导电夹92和透明导电层7的电接触面积。
如图16所示，作为改进的技术方案，在至少一个实施例中，所述凹形外壳5的侧部内表面52b与第二边缘表面21c之间的至少部分区域设有电极引出通道，所述电极采用u型导电夹的方式可拆卸地连接在第二导电基材上，所述u型导电夹包括第一导电夹91和第二导电夹92；该电致变色镜元件的第二导电基板由第二玻璃元件2和沉积在所述第二玻璃元件2第三表面21b上的薄膜叠层8组成，将第二玻璃元件2第三表面21b的部分周边区域进行减薄处理形成凹槽21，以限定出可容纳u型导电夹一端外壳侧部52厚度的空间，减薄处理的方法可选用化学蚀刻或者物理磨砂的方法进行，第三表面21b减薄处理的周边区域宽度小于等于密封件3在该周边区域的宽度，以防止电致变色介质4从凹槽21位置渗漏出空腔4a中，从而无法保证电致变色镜正常工作；薄膜叠层8沉积在第三表面21b并延伸至减薄处理后的凹槽21内，从而提供u型导电夹与薄膜叠层8的有效接触面积，且该u型导电夹与凹槽21部分是紧密配合的，从而有效保证薄膜叠层8和u型导电夹的电连通；所述第一导电夹91的一端延伸到第三表面21b上的凹槽21位置，并与凹槽21上的薄膜叠层8相接触形成电连通，而第一导电夹91的另一端延伸到第四表面21a上的外周区域的部分位置，进一步地通过在该位置处设置与电路板电连通所需的导电线束(未示出)，另外，将第二表面11b上沉积的至少部分透明导电层7采用蚀刻或者掩蔽的方式形成第一不导电区域71，以使第一导电基材和第二导电基材进行电绝缘；同时，所述第二导电夹92的一端延伸到第三表面21b上的凹槽21位置，并通过导电块31与第二表面11b上的透明导电层7形成电连通，所述导电块31至少部分区域埋设在密封件3中，以更好地固定导电块31在第二表面11b和第三表面21b之间，从而有效保证第二导电夹92与透明导电层7形成电连通，而第二导电夹92的另一端延伸到第四表面21a上的外周区域的部分位置，进一步地通过在该位置处设置与电路板电连通所需的导电线束(未示出)，另外，将第三表面21b上沉积的至少部分薄膜叠层8采用蚀刻或者掩蔽的方式形成 第二不导电区域81，以使第一导电基材和第二导电基材进行电绝缘，所述导电块可选用含有铜、银、镍等导电金属及其合金中的至少一种作为导电部件。该实施例中的u型导电夹组装完成后，另外还需要在延伸到第四表面21a的导电夹表面点焊至少一根电极引线，以便与引自电路板的电极引线进行电连接。上述改进的电极引出方式，通过第一导电夹91和第二导电夹92在凹槽21位置可灵活拆卸使用，并非通过密封件3完全固定在第二导电基板上而无法拆卸，或者说，该u型导电夹无需在涂覆密封件3时，即将u型导电夹固定在第二导电基板上，而是可以在整体密封件3涂覆并固化完成后，再进行u型导电夹灵活、快速、分批地进行组装完成，该技术构思可使电致变色镜引出电极的组装和更换更加方便灵活，使损坏后的电极更换成为可能。

作为一个可替代的实施方案，所述第一电极引线96的一端延伸到第三表面21b上的外周区域的部分位置，并固定在密封件3中，并非直接与第三表面21b上的薄膜叠层8相接触形成电连通，而是进一步地是通过设置导电银浆使第一电极引线96和薄膜叠层8建立了电连接关系，所述导电银浆可设置在电极引出通道位置，更进一步地，薄膜叠层8从第三表面21b延伸至第二边缘表面21c，以增大第一电极引线96和薄膜叠层8的电接触面积。所述第二电极引线97的一端延伸到第三表面21b上的外周区域的部分位置，并非直接与第二表面11b上的透明导电层7接触形成电连通，而是进一步地是通过设置导电银浆使第二电极引线97和透明导电层7建立了电连接关系，所述导电银浆可设置在电极引出通道与透明导电层连通的位置，即第一边缘表面11c、第二边缘表面21c和密封件3 外表面的连通位置，更进一步地，透明导电层7从第二表面11b延伸至第一边缘表面11c，以增大第二电极引线97和透明导电层7的电接触面积。
