具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施 例，都属于本申请保护的范围。
以下结合附图，详细说明本申请各实施例提供的技术方案。
本申请实施例公开了一种轨道灯，如图1至图6所示，包括导轨1、驱动电源2以及光源模组3。通常情况下轨道灯均为长条形结构，为了便于描述其结构，本实施例中采用长度方向X、宽度方向Y以及厚度方向Z来界定轨道灯。
导轨1是轨道灯的基础结构，用于固定驱动电源2以及光源模组3，同时导轨1也为驱动电源2提供电力。具体地，如图1、5、6所示，导轨1包括沿长度方向X延伸的轨道外壳10、绝缘件12以及导电线缆14。
其中，轨道外壳10通常为铝挤外壳，铝挤外壳具有良好的外观以及结构强度，还具有优良的加工成型工艺，综合性能较佳。轨道外壳10围绕形成容纳腔10a，容纳腔10a包括在厚度方向Z上的连接开口100以及与连接开口100相对的腔底102，容纳腔10a还包括在宽度方向Y上临近连接开口100且相对设置的两个腔壁104。绝缘件12用于固定导电线缆14，并隔绝电能防止短路。具体地，绝缘件12固定在容纳腔10a内，此时绝缘件12可以固定在腔底102上，也可以固定在腔壁104上。绝缘件12朝向容纳腔10a的中心的一侧设置有线缆槽120，导电线缆14固定在线缆槽120内。导电线缆14自身具有沿长度方向X延伸的裸露导电面，其导电面上任何一点均能够输送电能。需要说明的是，在有些实施例中，轨道外壳10也可能采用绝缘材料制造，此时也可以不设置绝缘件12，而是将导电线缆14直接固定在轨道外壳10上。
本实施例中的驱动电源2用于由导轨获取电能并输送至光源模组3。具体地，如图2、3、5、6所示，驱动电源2包括驱动外壳20、弹性导电端子22以及输出端子24，除此之外通常还包括驱动板28。驱动外壳20内可以设置端子导向槽200对弹性导电端子22进行导向，弹性导电端子22设置在端子导向槽200内且仅能够沿端子导向槽200弹出驱动外壳20。根据导电线缆14所处位置的不同，端子导向槽200的延伸方向也不同。例如，当导电线缆14沿厚度方向Z设置在腔底102的一侧时，端子导向槽200也沿厚度方向Z设置，而 当导电线缆14沿宽度方向Y设置在腔壁104的一侧时，端子导向槽200也沿宽度方向Y设置。
驱动板28也安装在驱动外壳20内，用于进行电源转换以及控制。为了便于弹性导电端子22以及驱动板28安装入驱动外壳20，本实施例中的驱动外壳20可以分为上壳20a和下壳20b两部分，两部分通过螺丝、卡扣等结构进行连接。
如图3所示，光源模组3通常包括发光组件30以及输入端子32，发光组件30与输入端子32电性连接。在驱动电源2安装完成后再将光源模组3的输入端子32与输出端子24连接即可实现光源模组3的电性连接过程。输入端子32与输出端子24可以采用公母端子结构，也可以采用插脚与金属弹片的配合结构，除此之外还可采用金手指连接、插针连接甚至焊接等各种连接结构。
本实施例中，线缆槽120与弹性导电端子22上可以设置导向面进行配合，在将驱动电源2由连接开口100放入容纳腔10a时，随着驱动电源2的逐渐深入，弹性导电端子22能够在导向面的导向下朝驱动外壳20内缩回，而在弹性导电端子22越过导向面后利用其自身的弹力能够沿宽度方向Y再次弹出并伸入线缆槽120内并与导电线缆14电性连接，驱动电源2与导轨1的电性连接过程十分简便，极大地节省了装配时间。
输出端子24设置在驱动外壳20在厚度方向Z的一侧并与弹性导电端子22电性连接，例如，弹性导电端子22与输出端子24同时与驱动板28电性连接。
如图2、3、6所示，本实施例中弹性导电端子22可以包括导电销220、弹性件222以及导电片224。导电销220用于伸出驱动外壳10并与导电线缆14电性连接。在导电销220上设置有抵接部220a，弹性导电端子22被设置在端子导向槽200内时，弹性件222的两端分别抵接抵接部220a以及端子导向槽200并对导电销220施加伸出驱动外壳10的作用力。弹性件222可以采用弹簧、弹片等各种弹性结构。导电片224设置在抵接部220a背离弹性件222的一侧 并在导电销220电性连接导电线缆14时抵接抵接部220a。此时输出端子24可与导电片224电性连接，以获得稳定的电性连接结构。
导电片224上可以设置装配缺口224a，导电销220由装配缺口224a伸入，这样导电片224至少可以由导电销220的两侧与抵接部220a进行抵接配合，因此能够提升电连接的稳定性。为了固定导电片224，可以在端子导向槽200上设置卡接口200a，导电片224卡接固定在卡接口200a内。此外，还可以将导电片224的两端弯曲或折叠，使导电片224由片状变为立体结构，进一步提升稳定性。
在本实施例中，导向面可以仅设置在线缆槽120上，例如将线缆槽120的卡钩边缘设计为弧形或斜向延伸的第一导向面120a。导向面也可以仅设置在弹性导电端子22上，例如将导电销220的端部设计为弧形的第二导向面220b。当然，第一导向面120a与第二导向面220b也可以同时存在，以提供更为优异的导向效果。并且，本实施例中导向面的具体形状也没有特别限制，只要能够实现导向功能均可。
电性连接需要形成回路，因此通常要同时连接电性相反的两极。在本实施例中，为了提高安全性，单条导电线缆14可以仅作为一极使用。因此为了形成回路，本实施例中的导电线缆14包括电性相反的第一导电线缆14a以及第二导电线缆14b，第一导电线缆14a与第二导电线缆14b在厚度方向Z上要相互错开，即距离连接开口100的距离不同。弹性导电端子22也同样包括第一弹性导电端子22a以及第二弹性导电端子22b，第一弹性导电端子22a与第二弹性导电端子22b的结构可以完全相同，但在厚度方向Z上也要相互错开。当驱动电源2安装至预定位置时，第一弹性导电端子22a与第一导电线缆14a电性连接，第二弹性导电端子22b与第二导电线缆14b电性连接，从而形成连接回路。
更进一步地，为了提高电连接的稳定性，本实施例还可以同时设置两个第一导电线缆14a以及两个第二导电线缆14b，两个第一导电线缆14a沿宽度方 向Y相对设置，两个第二导电线缆14b也沿宽度方向Y相对设置。
与此同时，在驱动电源2上，第一弹性导电端子22a以及第二弹性导电端子22b的数量同样均为两个，两个第一弹性导电端子22a沿宽度方向Y相背设置且分别与不同的第一导电线缆14a电性连接，两个第二弹性导电端子22b也沿宽度方向Y相背设置且分别与不同的第二导电线缆14b电性连接。两侧的弹性导电端子22的固定结构可以完全相同，也可以有所不同，只要对于电连接性能没有实质影响即可。例如通过分别设置在两侧的绝缘件12进行固定。
这样当驱动电源2伸入容纳腔10a内时可以同时与分设在的两个弹性导电端子22电性连接，相当于形成了两个相互并联的电路，因此安全性可以成倍提升。绝缘件12可以通过卡接的方式固定在腔壁104上，例如在墙壁104上设置第一卡槽104a，将绝缘件12卡接在第一卡槽104a内。
在本实施例中，为了快速安装驱动电源2，可以在导轨1的腔底102上设置第一磁性件16。与固定绝缘件12的方式相同，可以在腔底102上设置第二卡槽102a，将第一磁性件16通过第二卡槽102a卡接固定在腔底102上。与此同时，在驱动电源2内设置第二磁性件26，第二磁性件26可以固定在电源外壳20背离输出端子24的一侧。
当将驱动电源2由连接开口100放入时，第一磁性件16与第二磁性件26能够产生磁性吸附作用并使二者快速接近并最终固定连接在一起。而在磁性吸附过程中，弹性导电端子22与导电线缆14之间也会自动完成电性连接。当需要移动驱动电源2的位置时，只需要克服摩擦力拉动驱动电源2便可实现。在本实施例中，第一磁性件16以及第二磁性件26可以均为磁体，但这样成本较高。优选地，第一磁性件16可以采用磁性金属板，例如铁板，磁性金属板可以沿长度方向X延伸至导轨1的任意位置，第二磁性件26则采用磁石等磁体，利用磁体吸附磁性金属板。由于磁性金属板的价格低廉，因此可以有效降低成本。磁体可以通过卡钩等结构规定在驱动外壳20上。
光源模组3可以采用射灯、筒灯等，也可以采用线性模块，线性模块的光 源模组3通常还包括透镜34，透镜34用于为光源组件30配光，为了固定透镜，可以在腔壁104上设置卡条104b等结构来卡接固定透镜34，透镜34被固定后会覆盖连接开口100。此时可以将发光组件30与透镜34固定连接在一起，以提升二者的结构稳定性。
本申请实施例所提供的轨道灯能够节省装配时间。
本申请上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
