本发明提出一种纽扣电池组件，用以安装于含有用电器件的电子设备主体中，以向用电器件提供电能。
在本发明实施例中，如图1至图4所示，该纽扣电池组件包括导线连接座和纽扣电池50；
所述导线连接座包括外接板和固定环20；
所述纽扣电池50包括电芯51、金属外壳52和与所述金属外壳52密封连接的盖壳53；
所述电芯51的一极与所述金属外壳52电导通，所述电芯51的另外一极与所述盖壳53导通；
所述金属外壳52包括柱状主体和向外凸出的凸台521；
所述外接板包括绝缘本体10、金属弹性结构40、至少一个第一电极金属连接区13和至少一个第二电极金属连接区14；
所述绝缘本体10具有相背设置的导通面11和外接面12；
所述导通面11设置有所述金属弹性结构40，用于在发生弹性变化时电性接触所述盖壳53；
所述外接面12设置至少一个所述第一电极金属连接区13和至少一个所述第二电极金属连接区14；
至少一个所述第一电极金属连接区13与所述金属弹性结构40电导通；
固定环20，连接于所述外接板，并位于所述外接板的导通面11一侧， 所述固定环20沿所述外接板的周向延伸，以与所述外接板围合形成安装槽30，所述安装槽30用以收纳固定所述凸台521，并与所述凸台521电导通；
至少一个所述第二电极金属连接区14与所述固定环20电导通。
绝缘本体10可为圆形板，也可为方形板，具体不做限制。第一电极金属连接区13用以供用电设备的电极线焊接或者抵触接触电导通，用电设备的电极线可以是正极线，也可以是负极线，在此不做限制；具体举例说明，当第一电极金属连接区13与纽扣电池50的正极电导通，供用电设备的正极线与之进行焊接或者抵触接触电导通；当第一电极金属连接区13与纽扣电池50的负极电导通，供用电设备的负极线与之进行焊接或者抵触接触电导通。
固定环20的形状与绝缘本体10的形状对应，如圆环或方形环，以使固定环20与绝缘本体10所围合形成的安装槽30更加规整，举例而言，绝缘本体10设置为圆形板，固定环20设置为圆环，以使安装槽30与圆扣状的纽扣电池50适配。安装槽30可用以容置纽扣电池50整体，也可进容置纽扣电池50的端部，在此不做限制。纽扣电池50的一端装入安装槽30后，纽扣电池50的端面抵接于导通面11，纽扣电池50的其中一电极形成于该端面，该电极可以是正极，也可以是负极，具体不做限制。
导通面11与纽扣电池50接触的目的是为了更好地固定纽扣电池50，因此，导通面11与纽扣电池50可以直接接触，也可以间接接触，或者不接触，只需满足能稳定地确定纽扣电池50能够很好地稳固固定在安装槽30即可。优选地，导通面11是绝缘的，第一金属弹性结构40与纽扣电池50一极电接触后，通过绝缘本体10内部走线与第一电极金属连接区13形成电导通。
第二电极金属连接区14用以供用电设备的电极线焊接或者抵触接触电导通，可以是正极线，也可以是负极线，在此不做限制；具体举例说明，当第二电极金属连接区14与纽扣电池50的正极电导通，供用电设备的正极线与之进行焊接或者抵触接触电导通；当第二电极金属连接区14与纽扣电池50的负极电导通，供用电设备的负极线与之进行焊接或者抵触接触电导通。
纽扣电池50装入安装槽30后，正极抵接于绝缘本体10上的第一金属弹性结构40，负极抵接于固定环20，即纽扣电池50的正极可与绝缘本体10上 的第一电极金属连接区13电导通，从而焊接于第一电极金属连接区13的正极线可与纽扣电池50的正极电导通；纽扣电池50的负极可与绝缘本体10上的第二电极金属连接区14电导通，从而焊接于第二电极金属连接区14的负极线可与纽扣电池50的负极电导通，以使纽扣电池50与用电设备可通过纽扣电池50导向连接座形成电流回路。
由于用电设备的正极线和负极线都可焊接于绝缘本体10，因此可进一步降低用电设备与纽扣电池50的连接难度，提高连接效率和连接强度。与传统焊接在纽扣电池50的两个端面相比，本申请可以直接在一个面进行焊接，特别在自动化焊接的过程中可以一个步骤完成，提高了焊接效率，进一步，绝缘本体10上面的所述第一电极金属连接区13和所述第二电极金属连接区14的材质为铜、镍、锡或这些元素的合金。第一电极金属连接区13和第二电极金属连接区14用以供电极线焊接并导电，而铜、镍、锡能降低焊接时的连接难度，以进一步提高焊接效率。
此外，在更换纽扣电池50时，也无需再操作电极线，只需拆装纽扣电池50即可，进一步提高了纽扣电池50的更换效率。
进一步，为了便于进行焊接，本申请的第一电极金属连接区13和第二电极金属连接区14设置在同侧相邻的位置，这样便于进行自动焊接，也就是说可以同时完成用电设备的正极线和负极线的焊接。
当然，为了更好的适应各种设备，本申请的第一电极金属连接区13和第二电极金属连接区14可以设置多个，优选的，设置一个第一电极金属连接区13和两个第二电极金属连接区14，其中一个第一电极金属连接区13和一个第二电极金属连接区14设置在同侧相邻的位置，这样可以便于焊接；另外一个第二电极金属连接区14设置在与第一电极金属连接区13相对的另外一侧，这样可以便于进行抵触接触，使其在抵触接触的时候受力比较均匀。
可以理解为设置一个正极金属连接区和两个负极金属连接区，或两个正极金属连接区和一个负极金属连接区，其中一个正极金属连接区和一个负极金属连接区设置同侧相邻位置，另外一个正极金属连接区或负极金属连接区设置在另外一侧相对的位置，具体使用过程中，如果外接用电设备采用焊接的方式，可以优选的选择使用同侧相邻的正极金属连接区和负极金属连接区 可以便于焊接；如果是进行抵触电导通的方式，可以优选的选择使用两侧相对的正极金属连接区和负极金属连接区可以便于抵触电导通受力的时候均匀性，进而提高稳定性。
本发明纽扣电池组件使绝缘本体10和固定环20围合形成安装槽30，以供纽扣电池50的端部安装，纽扣电池50的端部装入安装槽30后，位于该端部的其中一电极可与金属弹性结构40电导通，从而使外接面12的第一电极金属连接区13可与纽扣电池50的一电极导通；另外一极与固定环20电导通，从而使外接面12的第二电极金属连接区14可与纽扣电池50的另外一电极导通；第一电极金属连接区13、第二电极金属连接区14用以供用电设备的正、负电极线焊接或者抵接接触，用电设备的电极线与第一电极金属连接区13、第二电极金属连接区14焊接后，可与纽扣电池50的电极导通，从而实现用电设备与纽扣电池50的电导通；由于用电设备的电极线是焊接于绝缘本体10，焊接固定或抵接接触的难度更小，因此焊接效率更高，从而可提高纽扣电池50与用电设备的安装连接效率。
此外，由于用电设备的电极线并不是直接焊接于纽扣电池50，若纽扣电池50的电能耗尽或出现故障，可通过从纽扣电池50导线连接座拆装纽扣电池50来实现更换，从而降低了纽扣电池50的更换难度，以提高对纽扣电池50的更换效率。
所述金属弹性结构40用以与装入所述安装槽30的纽扣电池50端部抵接。金属弹性结构40可为另外连接于绝缘本体10的导电金属弹性结构40，金属弹性结构40的具体形式不做限制，只需满足具有弹性并翘向安装槽30即可。金属弹性结构40可保证与纽扣电池50的抵接，从而提高绝缘本体10与纽扣电池50的电导通稳定性。
在一实施例中，如图1至图3所示，所述固定环20周向上的两相对位置分别凸设有扣板22，两所述扣板22扣接于所述外接面12。扣板22用以实现固定环20与绝缘本体10的固定连接，扣板22可与固定环20一体注塑成型，以提高结构强度，且降低加工难度。两扣板22连接于固定环20周向上的两相对位置，可增加固定环20与绝缘本体10的连接部位和外接面12积，以提高连接强度。扣板22扣接于绝缘本体10的外接面12后，可实现固定环20与外接面12的电性导通。
具体地，如图1至图3所示，所述绝缘本体10的周壁开设有定位槽15，所述扣板22的固定端与所述定位槽15配合。扣板22穿过定位槽15后再扣接于绝缘本体10，定位槽15能防止固定环20产生沿绝缘本体10周向转动的趋势，从而可提高固定环20与绝缘本体10的连接稳定性。
在实际应用中，如1图至图3所示，所述绝缘本体10的周壁开设有限位槽16，所述固定环20凸设有与所述限位槽16适配的限位筋23，所述限位筋23与所述限位槽16配合。限位筋23与限位槽16能增加固定环20与绝缘本体10在周向上的配合面积，以提高配合稳定性。限位筋23的数量可为两个，两限位筋23分设于固定环20周向上的两相对位置，限位槽16的数量和位置与限位筋23对于，以进一步增加固定环20与绝缘本体10的配合面积和配合位置，提高配合稳定性。
在一实施例中，如图2和图3所示，所述固定环20临近所述安装槽30槽口的一端沿径向朝内凸出，以形成固定台阶24，所述固定台阶24用以卡紧装入所述凸台521。纽扣电池50的凸台521与固定台阶24配合，以提高纽扣电池50与纽扣电池50导线连接座的配合稳固性。固定台阶24沿固定环20的周向延伸，凸台521沿纽扣电池50的周向延伸，以增加固定环20与纽扣电池50的配合面积，提高配合强度。
在一实施例中，如图2和图3所示，所述固定环20临近所述安装槽30槽口的一端开设有变形槽25，以供所述固定环20弹性扩张。纽扣电池50装入安装槽30时，需要将固定环20沿径向朝外挤压，以顺利进入安装槽30的槽口。变形槽25为固定环20的扩张变形提供了变形空间，从而使固定环20更容易弹性扩张，以使纽扣电池50进入安装槽30的过程更加简单方便。纽扣电池50进入安装槽30后，固定环20会产生沿径向朝内压固的趋势，从而可使固定环20卡紧纽扣电池50，以提高纽扣电池50的安装稳定性。
在一实施例中，如图1所示，所述固定环20连接于所述外接面12，所述外接面12设有接触点17，所述接触点17与所述固定环20电导通，并且所述接触点17与所述第二电极金属连接区14电导通。
结合上述扣板22的实施例，应该理解为扣板22不仅仅起到支撑固定连接的作用，还用以将固定环20与纽扣电池50的凸台521抵触接触形成的电导通传递到接触点17，以实现纽扣电池50的一极与第二电极金属连接区14 的电导通。
具体地，扣板22与接触点17之间的连接方式为焊接，以降低连接难度，能够有效的减少接触电阻，并提高连接强度。
优选的，本申请的绝缘本体10为PCBA板与PCB板，便于其他电子设备直接集成在上面，提高空间使用率。
具体地，所述纽扣电池50导线连接座还包括安装于所述外接面12的电路保护芯片，所述电路保护芯片与所述第一导通电路导通。电路保护芯片用以保护用电设备与纽扣电池50之间的电流稳定性，防止纽扣电池50或用电设备其中一者故障时对另一者造成损坏，以提高纽扣电池50导线连接座的电流传递稳定性。
在实际应用中，第一电极金属连接区13和第二电极金属连接区14上可分别设置正极标识和负极标识，以供焊接人员分辨，进一步降低焊接难度。
本发明还提出一种电子设备，该电子设备包括含有用电器件的电子设备主体以及如上所述的纽扣电池组件，该纽扣电池组件的具体结构参照上述实施例，由于本电子设备采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
其中，所述纽扣电池组件位于所述电子设备主体内，且所述用电器件的其中一极与所述第一电极金属连接区13电导通；另外一极与所述第二电极金属连接区14电导通。
以上所述仅为本发明的可选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
