背景技术
轨道灯具为满足快速拆装的需求，采用铜片从轨道上取电，铜片的固定多采用压簧结构，通过压簧顶住铜片，灯具安装到轨道上时，铜片与轨道铜条过盈配合，弹簧始终处于压缩状态，从而使铜片贴紧铜条以满足取电的要求。
目前，市场上的新式轨道灯具，为满足轨道超薄超窄的需求，将轨道灯具的尺寸进行缩小，由于尺寸受限，无法在轨道灯具内放置压簧结构实现取电，因此，只能通过铜片自身的塑性变形来满足从轨道取电的需求。然而，由于铜片塑性回弹性较差，很难回弹或回弹性不够，使得通过铜片自身变形回弹来顶住轨道铜条以实现取电的可靠性不高，同时，对铜片进行一次安装后，铜片变形，凸点下移，再次进行安装时，可能造成取电困难，不利于灯具的反复安装。
有鉴于此，确有必要对轨道灯提出改进，以解决上述问题。

请参阅图1至图3所示，本申请揭示了一种轨道灯100，用于对外界进行可移动式的照明。轨道灯100包括轨道200和与轨道200可拆卸连接的灯具300，外部电源与轨道200连接，轨道200与灯具300电性连接，通过轨道200向灯具300供电，实现灯具300发光并对被照物进行照明。
其中，灯具300包括电连接装置1、壳体2和发光组件3，壳体2内设有收容空间(未图示)，电连接装置1与壳体2相匹配并设于壳体2的顶部，使得部分电连接装置1能够收 容在该收容空间内，同时对该收容空间进行遮盖，电连接装置1远离壳体2的一侧与轨道200电接触，发光组件3收容在该收容空间内并与电连接装置1电性连接，如此设置，以实现轨道200通过电连接装置1对发光组件3进行供电。
具体请参阅图2和图3所示，电连接装置1包括基板11，基板11与壳体2连接并遮盖收容在壳体2内的发光组件3，基板11上设有锁扣14，轨道200上设有锁扣槽203，当基板11与轨道200连接时，锁扣14收容在锁扣槽203内，具体的，锁扣14设有两个，且设于灯具300的长边方向的两端，锁扣槽203设有一个且设于轨道200的中部位置并沿轨道200进行延伸，基板11上还设有与轨道200电连接的取电结构12，且取电结构12的延伸方向与锁扣14的延伸方向相同。如此设置，一方面通过锁扣14实现了灯具300与轨道200的固定连接，另一方面通过取电结构12实现了轨道200对灯具300进行供电。
因轨道200的具体结构、锁扣14的具体结构、发光组件3的具体结构、基板11的具体结构以及基板11和壳体2的连接关系均可按照现有的技术方案进行设计，此处不再详细描述。
本申请的主要改进点在于取电结构12、取电结构12和发光组件3的连接关系以及取电结构12与基板11的连接关系，故以下说明书部分将对取电结构12的具体结构、取电结构12分别与基板11和发光组件3的连接关系进行详细描述。
请参阅图3至图6并结合图9所示，电连接装置1包括基板11、插接固定在基板11上的取电结构12以及设于基板11与取电结构12之间的弹性件15，取电结构12设有凸部121，以与轨道200内的输电条201电性接触，弹性件15配置为在凸部121与输电条201相互挤压时产生弹性形变，使得凸部121与输电条201保持相互抵接，如此设置，使得输电条201能够持续的向取电结构12输电，保证电连接装置1与轨道200之间的连接稳定性。
具体的，取电结构12包括水平延伸的支撑板122和分别与支撑板122的两端垂直连接的连接部123，其中，支撑板122与基板11平行设置，且支撑板122设于基板11远离发光组件3的一侧，连接部123垂直于支撑板122设置。基板11上开设有供连接部123穿过的穿孔112，穿孔112贯穿基板11，且穿孔112的尺寸略大于连接部123的尺寸，使得连接部123能够穿过基板11并在穿孔112内移动，如此设置，使得取电结构12能够相对于基板11移动，当受到外力时，取电结构12压缩弹性件15并相对于基板11移动，当外力消失时，弹性件15推动取电结构12恢复至初始状态。
本实施例中，连接部123设有两个，且两个连接部123分别与支撑板122的两端连接，即取电结构12呈倒“U”型设置，穿孔112设有与连接部123相匹配的两个，使得两个连接部123均能够穿过穿孔112以伸入收容空间内，当然，在其他实施例中，连接部123可以仅设有一个，也可以设有三个，只要连接部123能够对基板11的两侧进行连接，并能够在穿孔112内移动即可，此处不做限制。
凸部121设于支撑板122上并自支撑板122朝向轨道200方向延伸，使得当电连接装置 1与轨道200连接时，凸部121能够与输电条201抵接，以实现电连接装置1与轨道200之间的电能输送，具体的，支撑板122呈平板状设置，凸部121呈椭圆状设置，凸部121设于支撑板122的中间位置且尺寸远小于支撑板122的尺寸，当然，当其他实施例中，凸部121可以设于支撑板122上的边缘位置，且凸部121的形状可以呈长条形或其它形状，此处不做限制。
在轨道灯100的长度方向上，弹性件15设于两个穿孔112之间，且一端与支撑板122抵接，另一端与基板11抵接，当电连接装置1与轨道200连接时，输电条201与凸部121抵接，并向凸部121施加压力，使得支撑板122朝向基板11的方向移动，此时弹性件15被挤压，直至输电条201对支撑板122施加的力与弹性件15的弹力相平衡，提高了凸部121与输电条201之间的连接稳定性；当电连接装置1与轨道200拆分时，凸部121与输电条201分离，弹性件15推动支撑板122朝向远离基板11的方向移动，使得取电结构12恢复至初始状态，以便于电连接装置1的再次安装。
具体的，弹性件15在支撑板122和基板11之间呈拱形设置，且弹性件15的最高点与支撑板122上对应凸部121的位置处相抵接，即弹性件15与基板11之间距离最大的位置处与支撑板122抵接。弹性件15自基板11朝向支撑板122的方向延伸，弹性件15远离基板11的一侧面设有抵接面124，该抵接面124能够与支撑板122贴合接触。在电连接装置1的短边方向上，弹性件15的尺寸与支撑板122的尺寸相匹配，使得电连接装置1与轨道200连接时，弹性件15不会与轨道200接触。
本实施例中，由于弹性件15远离基板11的一侧设有抵接面124，因此当取电结构12与弹性件15抵接时，抵接面124能够与支撑板122贴合，即弹性件15和取电结构12之间面接触，以增加弹性件15和取电结构12之间的抵接稳定性，使得弹性件15与取电结构12之间的受力面积增大。当然，在其他实施例中，弹性件15上也可以不设置抵接面124，即弹性件15与支撑板122之间呈线接触，此处不做限制。
本实施例中，在投影方向上，弹性件15和支撑板122均呈长条状设置，轨道200上设有导电槽202，输电条201收容在导电槽202内，弹性件15和支撑板122至少部分伸入导电槽202内，并使得凸部121与输电条201抵接，当然，在其他实施例中，轨道200上也可以不设置导电槽202，电连接装置1与轨道200组装时，凸部121直接与输电条201抵接，此处不做限制。
基板上还设有凸台113，凸台113自基板11朝向轨道200方向延伸，弹性件15自凸台113朝向远离基板11的方向延伸，输电条201设于导电槽202的底部，当电连接装置1与轨道200连接时，凸台113、弹性件15和部分取电结构12均能够伸入导电槽202内并使得取电结构12的凸部121与输电条201抵接，一方面避免在安装时操作人员碰触到输电条201，另一方面实现电连接装置1和轨道200之间的限位以及电连接。
本实施例中，取电结构12设有两个，两个取电结构12均设于基板11远离发光组件3 的一侧且位于基板11的同一端，以分别传输正极电流和负极电流，导电槽202和输电条201相对应的设有两个，且导电槽202自轨道200朝向远离基板11的方向凹陷，输电条201设于导电槽202的底部，以实现对发光组件3的供电，当然，在其它实施例中，取电结构12的数量可以设为其他数量，且取电结构12的位置可以设于基板11的中部位置，也可以设于壳体2的侧边，即取电结构12自电连接装置1朝向壳体2的方向延伸并穿过壳体2向外伸出，此时，至少部分壳体2收容在轨道200内，且轨道200内的输电条201相对应的设于轨道200的内侧面，使得取电结构12能够与输电条201抵接，此处不做限制。
本实施例中，弹性件15为具有塑性形变的塑料件，例如：聚碳酸酯材料制成的塑料件，当然，在其他实施例中，弹性件15可以为具有弹性的橡胶制品，弹性件15还可以为其他具有弹性的零件，例如体积小，弹性好的扭簧或弹簧，只要能够实现在组装时，取电结构12压缩弹性件15，在外力消失时，弹性件15能够推动取电结构12移动即可，此处不做限制。
本实施例中，弹性件15与基板11一体成型设置，以降低电连接装置1的生产成本，同时提高了电连接装置1的稳定性，当然，在其他实施例中，弹性件15可以通过连接胶或其它部件固定在基板11上，例如，弹性件15通过螺钉固定在基板11上，此处不做限制。
请参阅图3和图4并结合图7和图8所示，电连接装置1还包括电路板13，电路板13收容在壳体2的收容空间内，且电路板13的一端与连接部123远离支撑板122的一端连接、另一端与发光组件3连接，以实现取电结构12和发光组件3之间的电性连接。具体的，电路板13与连接部123焊接且未与壳体2或基板11连接，使得取电结构12能够带动电路板13在轨道200内同步移动，一方面实现了取电结构12和电路板13的稳定连接，另一方面避免连接部123从穿孔112中脱落。电路板13和发光组件3之间通过柔性导线(未图示)连接，使得电路板13在与发光组件3电性连接的同时能够相对于发光组件3移动，其中，柔性导线为能够导电以及变形的软线。
组装时，首先将连接部123穿过穿孔112，并将连接部123远离支撑板122的另一端与电路板13焊接，随后将电路板13与发光组件3通过柔性导线连接，随后将基板11与壳体2进行组装，然后将支撑板122和弹性件15与轨道200上的导电槽202相对应，并对灯具300施加压力，使得支撑板122伸入导电槽202内并使得凸部121与输电条201抵接，同时挤压弹性件15，直至锁扣14能够收容在锁扣槽203内并转动锁扣14，实现电连接装置1与轨道200的锁紧，实现灯具300与轨道200的电性连接；拆卸时，转动锁扣14，使得锁扣14从锁扣槽203中脱落，此时，取电结构12在弹性件15的推动下向外伸出至初始位置，便于灯具300再次组装。
综上所述，本申请的电连接装置1通过在取电结构12和基板11之间设置弹性件15，使得取电结构12能够在受到外部压力时朝向基板11移动，当外部压力消失时，取电结构12能够在弹性件15的作用下朝向远离基板11的方向移动，避免了取电结构12变形，同时，实现了电连接结构的反复安装使用；通过在基板11上设置穿孔112，使得取电结构12与基 板11活动连接，进一步避免了取电结构12在受到外力后变形；通过将电路板13设置为与连接部123焊接，实现了电路板13和取电结构12之间的稳定连接；通过柔性导线连接电路板13和发光组件3，实现了电路板13能够相对于发光组件3移动；通过将取电结构12设为U型，使得取电结构12与基板11的连接更稳定。
以上实施例仅用以说明本申请的技术方案而非限制，尽管参照较佳实施例对本申请进行了详细说明，本领域的普通技术人员应当理解，可以对本申请的技术方案进行修改或者等同替换，而不脱离本申请技术方案的精神和范围。
