 本发明的最佳实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
如图1至图4所示，本发明实施例提供了一种胶囊内窥镜，所述胶囊内窥镜包括胶囊壳体1和胶囊内核2；所述胶囊壳体1包括外壳11和透明前盖12；所述胶囊内核2包括天线22、电池23、N块PCB电路板24及第一摄像模块25、第一照明模块26、图像处理模块、信号传输模块和控制模块，其中N为正整数，且N≥2，，所述第一摄像模块25、所述第一照明模块26、所述FPC软排线27、所述图像处理模块、所述信号传输模块和所述控制模块集成在所述PCB电路板24上；所述外壳11近所述透明前盖12的端部设置有至少两个第一凸台111和至少两个第一凹槽112；第M块PCB电路板24M设置有至少两个第二凹槽24M1，其中M为正整数，且2≤M≤N，组装时，所述第二凹槽24M1与所述第一凸台111相配合，以使所述胶囊内核2装入所述外壳11内，组装完毕后，所述第一凸台111用于支撑所述第M块PCB电路板24M；所述第一摄像模块25集成在所述第M块PCB电路板24M上；所述胶囊内窥镜还包括定位构件3，所述定位构件3设置有至少两个第二凸台31，所述第二凸台31限位在所述第一凹槽112和第二凹槽24M1构成的限位槽内，所述第二凸台31的下表面与所述第一凹槽112的底面相抵接，所述定位构件3的底面与所述第M块PCB电路板24M的上表面相抵接，以使所述胶囊内核2在所述胶囊壳体1的圆周方向、径向方向和轴向方向上定位。
具体地，本实施例的胶囊内窥镜中以3块PCB电路板为例，即胶囊内核2包括从上往下平行设置的第一块PCB电路板241、第二块PCB电路板242和第三块PCB电路板243，所述第一照明模块26集成在所述第一块PCB电路板241上，所述第一摄像模块25和图像处理模块集成在所述第二块PCB电路板242上，所述信号传输模块和控制模块集成在第三块PCB电路板243上。本实施例中，第二块PCB电路板242以开设两个第二凹槽2421为例，两个第二凹槽2421均匀分布在第二块PCB电路板242的圆周上。
所述外壳11近所述透明前盖12的端部的内壁上设置有第一凸台111和第一凹槽112，第一凸台111的数量、第一凹槽112的数量分别与第二凹槽24M1的数量相同，本实施例中，第一凸台111和第一凹槽112分别为两个。两个第一凸台111均匀分布在外壳11内壁的圆周上，两个第一凹槽112均匀分布在外壳11内壁的圆周上，第一凸台111与第一凹槽112可以紧邻设置，也可以相隔一定距离设置，具体可以根据胶囊内窥镜的整体结构来设计。
定位构件3设置有第二凸台31，第二凸台31的数量与第二凹槽24M1的数量相同，本实施例中，第二凸台31为两个。
组装时，第二凹槽2421与第一凸台111相配合，且第二凹槽2421的尺寸大于第一凸台111的尺寸，保证在组装时，第二凹槽2421与第一凸台111存在一定间隙，以第二块PCB电路板242在垂直外壳11的轴向方向上顺利通过外壳11的内侧，从而实现胶囊内核2装入外壳11中；之后旋转所述胶囊内核2，使所述第二块PCB电路板242的下表面抵接在所述第一凸台111上，所述第二凹槽2421与所述外壳11的第一凹槽112形成限位槽，该限位凹槽的形状和尺寸分别与第二凸台31的形状和尺寸相适配；将定位构件3的第二凸台31置于所述第二凹槽24M1与所述外壳11的第一凹槽112形成的限位槽内，所述第二凸台31的下表面与所述第一凹槽112的底面相抵接，所述定位构件3的底面与所述第二块PCB电路板242的上表面相抵接，以使所述胶囊内核2在所述胶囊壳体1的圆周方向、径向方向和轴向方向上定位。
需要说明的是，组装时，胶囊内核2可以从外壳11的前端往下装入外壳11内，也可以从外壳11的后端往上装入外壳11内。对于胶囊内核2从外壳11的前端往下装入外壳11时，从第M+1块PCB电路板到最后一块PCB电路板中的每一块PCB电路板要避开第一凸台111，避开的方式可以是缩小第M+1块PCB电路板到最后一块PCB电路板中的每一块PCB电路板的尺寸，也可以是在第M+1块PCB电路板到最后一块PCB电路板中的每一块PCB电路板上开设凹槽，也可以是其他方式，在此对避开的方式不做限定。对于胶囊内核2从外壳11的后端往上装入外壳11时，胶囊壳体1包括后盖，外壳11的前端和后端都是开口的，后盖用于封住外壳11的后端，胶囊内核2从外壳11的后端往上装入外壳11内，之后用后盖将外壳11的后端封住。
本发明实施例提供的一种胶囊内窥镜，第二凹槽2421形成对第一凸台111的避让，保证了在组装时，第二块PCB电路板242在垂直外壳11的轴向方向上顺利通过外壳11的内侧，从而实现胶囊内核2装入外壳11中；胶囊内核2装入外壳11后，第二块PCB电路板242的下表面抵接在所述第一凸台111上，所述第二凹槽2421与所述外壳11的第一凹槽112形成限位槽，定位构件3的第二凸台31卡在所述第二凹槽24M1与所述外壳11的第一凹槽112形成的限位槽内，所述第二凸台31的下表面与所述第一凹槽112的底面相抵接，所述定位构件3的底面与所述第二块PCB电路板242的上表面相抵接，实现了所述胶囊内核2在所述胶囊壳体1的圆周方向、径向方向和轴向方向上定位。因此该胶囊内窥镜的结构稳定。
如图5和图7所示，在一些实施例中，所述透明前盖12的内壁设置有第一台阶面121，所述第一台阶面121抵接在所述外壳11的端面及所述第二凸台31的上表面，以使所述第M块PCB电路板24M在所述胶囊壳体1的轴向上定位；所述外壳11近所述透明前盖12的端部的外周设置有第三台阶面114，所述透明前盖12的端部与所述第三台阶面114配合。
本实施例中，第M块PCB电路板24M以第二块PCB电路板242为例，第一台阶面121抵接在所述外壳11的端面及所述第二凸台31的上表面，以使所述第二块PCB电路板242在所述胶囊壳体1的轴向上定位，透明前盖12的端部与所述第三台阶面114配合，进而得到结构更稳定的胶囊内窥镜。
如图6a和图6b所示，在一些实施例中，所述胶囊内核2包括FPC软排线27，每两块所述PCB电路板24之间通过所述FPC软排线27连接；所述外壳11开设有导向槽113，组装时，所述导向槽113用于与所述FPC软排线27配合，引导所述胶囊内核2装入所述外壳11内；组装完毕后，所述FPC软排线27限位在所述导向槽113内。
具体地，可以在外壳11上开设一凹槽作为导向槽，如图6a所示；也可以设置两条导向筋，该两条导向筋与外壳内壁形成导向槽，如图6b所示。导向槽113起导向作用，导向槽113的宽度大于FPC软排线27的宽度。组装时，FPC软排线27的一边沿着导向槽113的一边装入，同时第M块PCB电路板24M的第二凹槽24M1刚好对准外壳11的第一凸台111，将胶囊内核2装入外壳11内；当所述第M块PCB电路板24M的下表面超过所述第一凸台111的上表面时，旋转所述胶囊内核2，当旋转到一定角度时，胶囊内核2的FPC软排线27的另一边被导向槽113的另一边限位，使胶囊内核2停止转动，此时第M块PCB电路板的第二凹槽刚好与外壳11的第一凹槽形成限位槽，定位构件3的第二凸台可顺利的卡入此限位槽内，使所述胶囊内核2在所述胶囊壳体1的圆周方向上定位，因此胶囊内窥镜结构更稳定。
在一些实施例中，所述定位构件3包括至少两个定位块30，每个所述定位块30设置至少一个所述第二凸台31。
定位块30的个数可以根据需要进行设定。本实施例中，如图7所示，以定位构件3包括两个定位块30，每个定位块30设置有一个第二凸台31为例。定位块30的第二凸台31卡在所述第二凹槽24M1与所述外壳11的第一凹槽112形成的限位槽内，所述第二凸台31的下表面与所述第一凹槽112的底面相抵接，所述定位块30的底面与所述第二块PCB电路板242的上表面相抵接，实现了所述胶囊内核2在所述胶囊壳体1的圆周方向和径向方向上定位。因此该胶囊内窥镜的结构稳定。
如图8所示，在一些实施例中，所述胶囊壳体1还包括透明后盖13，所述透明后盖13的内壁设置有第二台阶面图中未示出；所述胶囊内核2还包括第二摄像模块28，所述第二摄像模块28集成在第P块PCB电路板24P上，其中M＜P≤N；所述第P块PCB电路板24P的下表面与所述外壳11近所述透明后盖13的端面相抵接，所述第二台阶面131与所述第P块PCB电路板24P的上表面相抵接，使所述第P块PCB电路板24P在胶囊壳体1的轴向方向上定位，从而实现了双镜头胶囊内窥镜的结构稳定性。所述外壳11近所述透明后盖13的端部的外周设置有第四台阶面在图中未示出，所述透明后盖13的端部与所述第四台阶面配合，提高了双镜头胶囊内窥镜的结构稳定性。
如图9所示，进一步地，所述电池23为聚合物锂电池，所述聚合物锂电池的外壳为塑料，所述聚合物锂电池的形状为不规则形状；所述胶囊内核2包括磁铁21，所述磁铁21的形状与所述聚合物锂电池的形状相适配。
具体地，电池23和磁铁21设置在第R块PCB电路板和第Q块PCB电路板之间，R、Q为正整数，R≥M，Q≤P，由于第M块PCB板和第P块PCB板已限位，电池23的上下两个端面可以不用分别与第R块PCB电路板和第Q块PCB电路板的端面相抵接，从而使电池23的端面可以是自由曲面的可能性，从而使电池23的形状可以是不规则的形状。
聚合物锂电池与氧化银电池相比，具有质量小，负载能力强，能量密度高等优点，从而能较大减小胶囊内窥镜的重量；为了减轻胶囊内窥镜的重量，聚合物锂电池采用塑料外壳包裹，塑料外壳包裹的聚合物锂电池为不规则的形状，会浪费胶囊内窥镜的内部空间，将磁铁21的形状做成与聚合物锂电池的形状相适配，从而充分利用胶囊内窥镜的内部空间，提高磁铁21的磁性。
如图8所示，在一些实施例中，所述天线22布置在所述胶囊壳体1和所述胶囊内核2的间隙中，从而达到节省胶囊内窥镜空间的目的。 比如，对于双镜头的胶囊内窥镜，天线22布置在胶囊壳体1和胶囊内核2的间隙，从而达到节省胶囊内窥镜空间的目的。
在一些实施例中，所述第一照明模块26集成在第一块PCB电路板241上，所述第一块PCB电路板241开设有第一通孔，所述第一摄像模块25的摄像头穿过所述第一通孔，所述第一块PCB电路板241的下表面通过粘接剂固接在所述第一摄像模块25的台阶面上，提高了胶囊内窥镜的结构稳定性。
在一些实施例中，所述胶囊内核2还包括第二照明模块和第二摄像模块，所述第二照明模块集成在最后一块PCB电路板上，所述最后一块PCB电路板开设有第二通孔，所述第二摄像模块的摄像头穿过所述第二通孔，所述最后一块PCB电路板的下表面通过粘接剂固接在所述第二摄像模块的台阶面上，实现了双镜头胶囊内窥镜的结构稳定性。
如图10所示，本发明实施例提供一种胶囊内窥镜的组装方法，应用上述任一实施例所述的胶囊内窥镜，包括如下步骤：
S11：将第M块PCB电路板24M的第二凹槽24M1对准外壳11的第一凸台111，将胶囊内核2装入所述外壳11内；
S12：当所述第M块PCB电路板24M的下表面超过所述第一凸台111的上表面时，旋转所述胶囊内核2，使所述第M块PCB电路板24M的下表面抵接在所述第一凸台111上，所述第二凹槽24M1与所述外壳11的第一凹槽112形成限位槽；
S13：将定位构件3的第二凸台31置于所述第二凹槽24M1与所述外壳11的第一凹槽112形成的限位槽内，所述第二凸台31的下表面与所述第一凹槽112的底面相抵接，所述定位构件3的底面与所述第M块PCB电路板24M的上表面相抵接，以使所述胶囊内核2在所述胶囊壳体1的圆周方向、径向方向和轴向方向上定位。
本发明实施例提供的胶囊内窥镜的组装方法，组装时，第二凹槽24M1形成对第一凸台111的避让，保证了在组装时，第M块PCB电路板24M在垂直外壳11的轴向方向上顺利通过外壳11的内侧，从而实现胶囊内核2装入外壳11中；胶囊内核2装入外壳11后，将第M块PCB电路板24M的下表面抵接在所述第一凸台111上，所述第二凹槽24M1与所述外壳11的第一凹槽112形成限位槽，将定位构件3的第二凸台31卡在所述第二凹槽24M1与所述外壳11的第一凹槽112形成的限位槽内，所述第二凸台31的下表面与所述第一凹槽112的底面相抵接，所述定位构件3的底面与所述第M块PCB电路板24M的上表面相抵接，实现了所述胶囊内核2在所述胶囊壳体1的圆周方向和径向方向上定位；最后在外壳的前端和后端分别盖上透明前盖和后盖，完成胶囊内窥镜的组装，该组装方法简单，得到的胶囊内窥镜的结构稳定。需要说明的是，胶囊内核2也可以从外壳11的前端往下装入外壳11内，这时，从第M+1块PCB电路板到最后一块PCB电路板中的每一块PCB电路板要避开第一凸台111，避开的方式可以是缩小第M+1块PCB电路板到最后一块PCB电路板中的每一块PCB电路板的尺寸，也可以是在第M+1块PCB电路板到最后一块PCB电路板中的每一块PCB电路板上开设凹槽，也可以是其他方式，在此对避开的方式不做限定，这种情况下，后盖与外壳的后端可以一体成型，也可以分开设置，不做限定。
