具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅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作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。
相关技术中的眼镜，在生产、制造以及使用过程中，通常只适应于固定尺寸头围的用户，而用户的身体尺寸千差万别，这导致眼镜的适用性差。当用户购买的眼镜的两个镜腿间距较近时，无法佩戴。基于此，本申请的发明人提出了本申请各实施例的转轴机构、镜架、眼镜以及智能眼镜，以期改善上述缺陷，提供眼镜的镜架的适用性。以下结合附图具体描述本申请的各实施例。
参阅图1，本实施例提供一种眼镜10，其中，眼镜10包括镜架30和镜片20，镜片20可以装配于镜架30上。其中，镜片20可以是平光镜片、近视镜片、老花镜片、滤光镜片、彩色镜片等各类镜片，在此不做限定。镜片20可以是玻璃、树脂等材质，在此不做限定。在其他的一些实施方式中，也可以不设置镜片20，此时眼镜10可以仅作为用户的一种装饰性用具。
镜架30包括镜腿50、镜框40以及转轴机构100，其中镜框40用于安装镜片20，镜腿50连接镜框40并用于供用户进行穿戴。需要说明的是，镜框40以及镜腿50均可以是由金属、塑料、陶瓷等各种材质制成，在此不做限定。镜框40可以包括两个独立的框体结构，用于安装两块彼此分离的镜片20，并分别与用户的左眼以及右眼对应。
镜腿50可以为两个，两个镜腿50分别设置于镜框40的相对的两侧，并与镜框40连接。两个镜腿50大致呈对称结构布置，镜腿50通过转轴机构100铰接于镜框40，以便于收纳镜腿50。具体而言，镜框40设置有延伸部41，延伸部41相对于镜框40弯折设置，转轴机构100设置于延伸部41的远离镜框40的一端，镜腿50连接转轴机构100，镜腿50的远离转轴机构100的一端弯折形成耳挂55，耳挂55适于悬挂于用户的耳部。
具体而言，本实施例中，请一并参阅图2和图3，延伸部41包括第一底壳42和第一盖板43，第一底壳42内形成第一内容腔44，第一内容腔44用于装配转轴机构100的一部分，第一盖板43可以与第一底壳42形成装配，并至少部分的封闭第一内容腔44。第一内容腔44可以贯穿第一底壳42的一端，以使转轴机构100可以伸入第一内容腔44内形成安装。
镜腿50包括第二底壳51和第二盖板52，第二底壳51内形成第二内容腔53，第二内容腔53位于第二底壳51的靠近延伸部41的一端，第二内容腔53用于装配转轴机构100的一部分，第二盖板52可以与第二底壳51形成装配，并至少部分的封闭第二内容腔53。第二内容腔53可以贯穿第二底壳51的一端，以使转轴机构100可以伸入第二内容腔53内形成安装。
参阅图4，转轴机构100包括固定支架110、内折支架130、外翻支架150以及弹性件170， 其中，内折支架130转动连接于固定支架110，外翻支架150转动设置于内折支架130，弹性件170设置于内折支架130和外翻支架150之间，用于形成对外翻支架150的回复力。
本实施例中，如图5所示，固定支架110包括呈角度连接的第一固定板111、第二固定板112、第一安装部113以及第二安装部114，第一固定板111和第二固定板112之间形成的夹角例如可以是85°-95°，第一安装部113和第二安装部114连接于第二固定板112，第一安装部113和第二安装部114位于第二固定板112的同侧，且第一安装部113和第二安装部114与第一固定板111位于第二固定板112的同侧，第一安装部113和第二安装部114相对设置，并用于与内折支架130形成装配，以使内折支架130与固定支架110转动连接。具体的，第一安装部113设置有第一通孔1131，第二安装部114设置有第二通孔1141，第一通孔1131和第二通孔1141同轴设置。
第一安装部113与第一固定板111之间形成第一间隙116，第二安装部114与第一固定板111之间形成第二间隙117，第一间隙116和第二间隙117大致等宽设置，第一间隙116和第二间隙117可以供容置部分的内折支架130。第二固定板112还具有端面1123，端面1123位于第二固定板112的远离第一固定板111的一端，且端面1123大致与第二固定板112所在平面相互垂直。
固定支架110的第一固定板111连接有第一连接部115，第一连接部115用于与延伸部41连接，第一连接部115相对于第一固定板111弯折设置，且大致与第二固定板112所在平面相互平行，这种设置方式，可以减小第一连接部115占用的体积。连接时，第一连接部115可以伸入第一内容腔44，并与第一底壳42装配固定，例如通过螺钉固定，这样第一连接部115可以完全隐藏于延伸部41内部，外部无法看到，保证整个镜架30的外观的一致性。作为一种更为具体的实施方式，第一连接部115包括两个悬耳，每个悬耳上开设有通孔，通孔的轴线大致与第二固定板112所在平面相互垂直，当第一连接部115伸入第一内容腔44内时，可以通过螺钉穿过通孔，将第一连接部115固定于固定支架110。在其他的一些实施方式中，第一连接部115也可以设置成卡接结构，直接通过卡合固定的方式与延伸部41连接。
请一并参阅图5和图6，内折支架130包括第一转动部131、第二转动部135以及挡板138，第一转动部131转动连接固定支架110，具体地，第一转动部131嵌入第一安装部113和第二安装部114之间，转轴机构100还包括一销钉180，销钉180穿过第一通孔1131以及第二通孔1141，并连接于第一转动部131，使得第一转动部131转动装配于第一安装部113和第二安装部114。
作为一种更为具体的实施方式，请继续参阅图6和图7，第一转动部131包括第三板体1311、第四板体1312以及弧形板1313，第四板体1312与第三板体1311相对设置，第三板体1311开设有第三通孔1314，第四板体1312开设有第四通孔1315，第三通孔1314和第四通孔1315同轴设置，且与第一通孔1131和第二通孔1141同轴设置，销钉180同时穿过第一通孔1131、第二通孔1141、第三通孔1314以及第四通孔1315，第三板体1311、第四板体1312、第一安装部113以及第二安装部114形成转动副，这样第一转动部131可以相对于固定支架110转动。
请结合图5、图6以及图7，弧形板1313连接于第三板体1311和第四板体1312之间，弧形板1313至少部分位于第一安装部113以及第二安装部114之间，弧形板1313大致呈圆弧形结构，并且弧形板1313在转动过程中，可以嵌入第一间隙116和第二间隙117内。
由于内折支架130在相对固定支架110转动的过程中，仅需要转动大致80°-100°的范围即可，因此参阅图5和图7，固定支架110还可以包括限位件118，限位件118用于限制第一转动部131的转动角度，避免第一转动部131相对于固定支架110转动过大的角度，反而不便于收纳。限位件118可以设置于第一转动部131的转动路径上，当第一转动部131转动过程中与限位件118接触时，即可以实现限位功能。作为一种更为具体的实施方式，本实施例中，限位件118设置于弧形板1313的转动路径上，这种设置方式，限位件118不会影响销钉180的动作，避免因设置限位件118而与其他零部件产生干涉。具体地，限位件118连接 于第二固定板112，并与第一安装部113和第二安装部114位于第二固定板112的同侧，限位件118设置于第一间隙116和/或第二间隙117内，在弧形板1313转动过程中，弧形板1313可以与限位件118抵接形成限位。可以理解的是，限位件118可以仅设置于第一间隙116内，或者仅设置于第二间隙117内，均可以实现限位效果。本实施例中，为了保证固定支架110的外观一致性，同时避免在弧形板1313与限位件118接触过程中，受力不均，限位件118设置为两个，两个限位件118分别设置于第一间隙116内和第二间隙117内，这样，当弧形板1313与限位件118接触时，同时与两个限位件118抵接，弧形板1313两端的受力均衡，避免出现歪斜等现象。
请继续参阅图7，弧形板1313与第一固定板111和第二固定板112之间均具有间隙119，即弧形板1313和第一固定板111以及第二固定板112之间均未直接接触，间隙119可以供设置柔性电路板80等其他的元器件。需要说明的是，弧形板1313与第一固定板111之间的间隙119与弧形板1313与第二固定板112之间的间隙119是相互连通的。间隙119的设置还便于弧形板1313的转动，避免弧形板1313在转动过程中与第一固定板111或第二固定板112发生干涉。
请再次参阅图6，第二转动部135包括相对设置的第一板体1351和第二板体1352，第一板体1351以及第二板体1352用于转动连接外翻支架150。第一板体1351和第二板体1352均连接于第一转动部131，具体的，第一板体1351连接第三板体1311并大致位于同一平面，第二板体1352连接第四板体1312并大致位于同一平面，第一板体1351具有第一台阶面13511，第二板体1352具有第二台阶面(图未示出)，第一台阶面13511和第二台阶面可以共面设置，且第一台阶面13511和第二台阶面均可以与第二固定板112的远离第一固定板111的端面1123配合。具体的，第一转动部131相对于固定支架110转动的过程中，第一台阶面13511和第二台阶面可以转动至与第二安装板1514所在平面相互平行，也可以转动至与第二安装板1514所在平面相互垂直，当第一台阶面13511和第二台阶面转动至与第二安装板1514所在平面相互垂直时，第一台阶面13511和第二台阶面可以抵持于端面1123，此时受到端面1123的限制，第一转动部131无法继续转动，进而实现对第一转动部131的转动角度的限制。
限位件118和端面1123可以共同限定内折支架130的主动角度，使得第一转动部131可以转动的角度大致为80°-100°，特别的，第一转动部131可以转动的角度大致为90°。在第一转动部131转动过程中，当第一台阶面和第二台阶面转动至与第二固定板112所在表面相互平行时，内折支架130处于展平状态(如图7所示状态)，当第一台阶面和第二台阶面转动至与第二固定板112所在表面相互垂直时，内折支架130处于内折状态(如图8所示状态)。如图9所示，当内折支架130相对于固定支架110内折时，延伸部41和镜架腿之间会形成缝隙X，此时弧形板1313位于缝隙X处，可以对缝隙X形成遮挡，相当于弧形板1313的至少一部分外露作为转轴机构100或镜架30的部分外观面，这样可以避免转轴机构100的内部结构外露，提高外观一致性；同时也防止灰尘等异物进入到第一通孔1131、第二通孔1141内卡死销钉180，造成转动困难。当内折支架130处于展平状态时，延伸部41和镜架腿大致位于同一直线上，此时延伸部41和镜架腿之间形成的缝隙很小或者不存在缝隙。
请再次参阅图6，第一板体1351和第二板体1352之间形成空腔1316，空腔1316连通间隙119，当眼镜10为智能眼镜10时，空腔1316和间隙119可以作为设置柔性电路板80等零部件的通道。同时，空腔1316还可以具有开口1317，开口1317连通空腔1316。在一些实施方式中，为了便于柔性电路板80等的设置，参阅图5，第二固定板112的朝向第一转动部131的表面设置有避让槽1121，避让槽1121可以通过在第二固定板112的表面开凿形成，也可以有第二固定板112的朝向第一转动部131的表面直接凹陷形成避让槽1121，避让槽1121与间隙119以及空腔1316连通，通过设置避让槽1121，当柔性电路板80经过第二固定板112时，可以对柔性电路板80进行更好的限位，同时也可以通过厚度更厚的柔性电路板80，便于应用更大的光机60。
请继续参阅图6，挡板138连接于第二转动部135并位于第二转动部135的远离第一转 动部131的一侧，挡板138朝向远离第一转动部131的一侧伸出。作为一种更为具体的实施方式，本实施例中，内折支架130还包括一连接板1353，连接板1353连接于第一板体1351和第二板体1352之间，第一板体1351、第二板体1352以及连接板1353共同围成空腔1316。挡板138连接于连接板1353并朝向远离第一转动部131的一侧伸出，挡板138与连接板1353之间形成大致为90°的夹角。且挡板138邻近于开口1317设置，挡板138所在平面与第一台阶面13511和第二台阶面大致相互平行。
请一并参阅图7和图10，外翻支架150包括相连接的第二连接部151和第三连接部155，第二连接部151转动设置于内折支架130。在一些实施方式中，外翻支架150可以通过销轴与内折支架130的第二转动部135枢接，实现相互转动。
本实施例中，结合图6和图7，第二转动部135设置有第一弧形限位槽1355，第一弧形限位槽1355可以同时开设于第二转动部135的第一板体1351和第二板体1352，且第一板体1351开设的第一弧形限位槽1355与第二板体1352上开设的第一弧形限位槽1355位置对应，即第一板体1351开设的第一弧形限位槽1355在第二板体1352所在平面的正投影与第二板体1352开设的第一弧形限位槽1355可以完全重合。同样的，第二板体1352开设的第一弧形限位槽1355在第一板体1351所在平面的正投影与第一板体1351开设的第一弧形限位槽1355可以完全重合。第一弧形限位槽1355所在的弧线可以是圆弧，且第一弧形限位槽1355所在弧线的圆心位于内折支架130的外侧，内折支架130的外侧与镜腿50的外侧为同侧。
如图7所示，转轴机构100还包括限位销190，本实施例中，限位销190为与第一弧形限位槽1355配合的弧形销，并且第一弧形限位槽1355的弧长大于限位销190的弧长，以使得限位销190可以嵌入第一弧形限位槽1355。限位销190可以在第一弧形限位槽1355内沿第一弧形限位槽1355的延伸方向滑动，限位销190同时连接第二连接部151，这样当第二连接部151受外力时，带动限位销190在第一弧形限位槽1355内滑动，此时第二连接部151相对于第二转动部135转动，实现外翻支架150相对于内折支架130之间的相对转动。可以理解的是，外翻支架150相对于内折支架130转动时，朝向内折支架130的外侧转动。
需要说明的是，外翻支架150相对于内折支架130的可转动角度受到第一弧形限位槽1355的弧长的限定，当限位销190到达第一弧形限位槽1355的两个端点时，即为外翻支架150相对内折支架130转动时的最大转动角度。这种设置方式，既实现了外翻支架150与内折支架130的转动连接，又可以限定外翻支架150和内折支架130之间的转动角度。
限位销190可以与第二连接部151固定连接，例如通过一体成型的方式结合，也可以采用卡接的方式相对固定。为了便于装配限位销190，本实施例中，如图10所示，第二连接部151包括第五板体1511、第六板体1512、第一安装板1513和第二安装板1514，第五板体1511和第六板体1512相对设置，第三连接部155连接于第五板体1511和第六板体1512，第一安装板1513连接于第五板体1511和第六板体1512之间，且第一安装板1513与第五板体1511和第六板体1512之间大致形成90°夹角。第二安装板1514连接于第五板体1511和第六板体1512之间，且第二安装板1514与第五板体1511和第六板体1512之间大致形成90°夹角。第一安装板1513和第二安装板1514相互连接且形成大致为90°的夹角。
装配时，第五板体1511靠近第一板体1351，并且可以与第一板体1351贴合，第六板体1512靠近第二板体1352，并且可以与第二板体1352贴合，其中，第五板体1511和第六板体1512可以位于第一板体1351和第二板体1352之间。本实施例中，第一板体1351和第二板体1352可以位于第五板体1511和第六板体1512之间，即第二转动部135可以嵌入第五板体1511和第六板体1512之间形成的空间内。
外翻支架150的第五板体1511和第六板体1512设置有与第一弧形限位槽1355配合的第二弧形限位槽1515，第二弧形限位槽1515的设置位置与第一弧形限位槽1355的位置对应，以使得限位销190可以至少部分嵌入第二弧形限位槽1515。第二弧形限位槽1515可以与第一弧形限位销190具有相同的弧度和弧长，且第一弧形限位槽1355和第二弧形限位槽1515的圆心可以重合。限位销190可以是两个，一个限位销190穿设于第一板体1351开设的第一 弧形限位槽1355以及第五板体1511开设的第二弧形限位槽1515，另一个限位销190穿设于第二板体1352开设的第一弧形限位槽1355以及第六板体1512开设的第二弧形限位槽1515，使得限位销190同时连接内折支架130和外翻支架150，且两个限位销190可以保持同步的运动。这种设置方式的好处在于装配时，只需将限位销190退出，既可以分离内折支架130和外翻支架150，拆卸方便，便于组装、维修等。
需要说明的是，在其他的一些实施方式中，限位销190也可以不是弧形销，此时限位销190可以设置成圆销、方形销等，只需保证限位销190可以在第一弧形限位槽1355和第二弧形限位槽1515内滑动即可。
第三连接部155位于第二连接部151的远离内折支架130的一侧，并用于与镜腿50连接，本实施例中，第三连接部155连接于第二安装板1514，第三连接部155形成有一安装腔，第二安装板1514设置有缺口，缺口连通安装腔，挡板138可以越过第二连接部151，并从缺口穿过进而覆盖安装腔，挡板138和第三连接部155之间形成安装空间1551，安装空间1551用于设置弹性件170。本实施例中安装腔即为安装空间1551。第三连接部155还设置有第五通孔1552和第六通孔1553，第五通孔1552和第六通孔1553分别位于安装腔的相对的两侧，第五通孔1552和第六通孔1553用于用镜腿50实现连接，具体地，第三连接部155可以伸入第二内容腔53内，通过螺钉穿过第五通孔1552和第六通孔1553连接镜腿50的第二底壳52以及第二盖板53，实现与镜腿50的相对固定。
弹性件170用于提供弹性回复力，如图7所示，弹性件170设置于安装空间1551内，弹性件170的两端分别抵接于挡板138和第三连接部155，以为第三连接部155以及外翻支架150提供回复力，当外翻支架150相对于内折支架130外翻时，外翻支架150相对于内折支架130转动，外翻支架150的第三连接部155朝向靠近挡板138的方向转动，弹性件170被第三连接部155挤压发生形变，此时弹性件170向外翻支架150施加反向的回复力，以使外翻支架150具有恢复到初始状态的趋势。这样设置的好处在于，当用户在佩戴眼镜10的过程中，需要扩展镜腿50的张开角度时，可以向内折支架130的外侧翻转外翻支架150，扩大两个镜腿50之间的间距，此时外翻支架150相对于内折支架130外翻(如图11所示状态)，由于弹性件170提供外翻支架150的复位力，当用户佩戴上眼镜10后，外翻支架150在复位力作用下，会使得两个镜腿50夹住用户的头部，提高眼镜10佩戴过程的稳定性，同时不会使得镜腿50过渡的向外侧扩展。
本实施例中，由于挡板138越过第二连接部151后与第三连接部155形成安装空间1551，因此弹性件170设置于第三连接部155和挡板138之间，实现了对弹性件170的隐藏，提高整个转轴机构100的外观一致性。同时，由于第三连接部155位于第二连接部151的远离内折支架130的一侧，也就是远离第二连接部151与内折支架130的转动轴线的位置，因此在保证外翻支架150的外翻角度固定的情况下，第三连接部155的转动路径更长，对弹性件170的压缩量更大，能够提供更大的回复力，因此弹性件170不需要使用弹性系数过大的材料或结构，降低制造成本，也使得用户在外翻外翻支架150时变得更加轻松。
可以理解的是，弹性件170可以是弹簧、板簧等装置，本实施例中，作为一种方式，弹性件170为蛇形板簧结构，其安装于安装空间1551内，蛇形板簧的两个自由端分别抵接挡板138和第三连接部155。采用蛇形板簧具有以下优点：弹性件170与挡板138和第三连接部155的接触面积更大，同时弹性系数更大。
当内折支架130处于展平状态，且外翻支架150未相对于内折支架130转动时，第一安装板1513与与第二固定板112大致处于相互平行的状态，此时限位销190位于第一弧形限位槽1355的靠近销钉180的轴线的端部，当内折支架130处于展平状态，且外翻支架150相对于内折支架130外翻时，第一安装板1513与第二固定板112之间形成夹角，且第一安装板1513与内折支架130之间会形成缝隙，该缝隙形成于外翻支架150与内折支架130之间，若缝隙外露，不利于转轴机构100的防尘，也不美观。
因此，在一个更为具体的实施方式中，参阅图7，第二固定板112的远离第一固定板111 的一端至少部分嵌入外翻支架150形成遮挡部1122，具体的，遮挡部1122可以部分的嵌入第五板体1511和第六板体1512之间，外翻支架150相对于内折支架130朝向内折支架130的外侧转动时，遮挡部1122可以遮盖外翻支架150与内折支架130之间形成的缝隙，这样可以提高整个转轴机构100的外观一致性。
进一步地，为了防止遮挡部1122伸入外翻支架150的过程时，外翻支架150外翻过程中，与第一安装板1513发生干涉，本实施例中，第一安装板1513的远离第三连接部155的一端可以弯折形成一台阶，第二固定板112的远离第一固定板111的一端朝向相反的方向弯折形成遮挡部1122，遮挡部1122可以嵌入到台阶处，这样，当外翻支架150与内折支架130未发生相对转动时，外翻支架150的第一安装板1513可以与第二固定板112抵接或者邻近于第二固定板112，当外翻支架150相对于内折支架130外翻时，外翻支架150的第一安装板1513与内折支架130间形成缝隙，此时遮挡部1122外露作为转轴机构100的部分外观面，整体更加美观。
在另一个实施例中，如图12所示，眼镜10还可以是智能眼镜，智能眼镜可以包括镜架30、显示部70、光机60以及柔性电路板80(图13中示出)，其中镜架30的结构可以参阅前述内容，在此不再赘述。
光机60设置于镜腿50，并用于调制图像光，以在显示部70投影形成图像，光机60可以是各类型的光机60系统，在此不做具体限定，其中光机60可以是一个也可以是两个，或者为多个，本实施例中，光机60为一个，设置于一个镜腿50上，并负载于镜腿50的顶部。显示部70设置于镜框40，其中显示部70可以是一半透半反镜片20，例如显示部70可以透过除红光外的可见光光线，并可以反射红光光线，光机60调制的图像光可以使用红光，图像光投影到显示部70时被反射入人眼，用户可以观看到光机60投影的内容，同时环境光中的非红光的可见光可以透过显示部70进入人眼，用户可以在观看光机60投影内容的同时看到环境中的物体。在另一种实施方式中，镜框40上可以设置普通镜片20，显示部70同时设置于镜框40，并位于镜片20前方，形成一相对于镜片20独立的显示界面。在此均不做具体限定。
柔性电路板80(Flexible Printed Circuit，FPC)的一端电性连接光机60，另一端电性连接显示部70，以在光机60和显示部70之间形成信号传输路径，其中柔性电路板80可以沿镜腿50走线，并经过转轴机构100。例如：在一种实施方式中，柔性电路板80可以沿镜腿50并贴设于镜腿50表面走线。
为了便于隐藏柔性电路板80，同时起到对柔性电路板80的保护作用，本实施例中，参阅图13，柔性电路板80连接光机60后，可以从第二底壳51和第二盖板52之间的缝隙内走线，延伸至转轴机构100处，柔性电路板80在经过转轴机构100时，可以按以下方式走线：柔性电路板80贴设于挡板138并从开口1317进入空腔1316内，经过间隙119后绕过内折支架130的弧形板1313从固定支架110穿出后进入第一底壳42和第一盖板43之间的缝隙，并继续延伸至镜框40与显示部70电性连接。由于柔性电路板80在经过转轴机构100走线时，均是从空腔1316和间隙119中经过，因此不会影响外翻支架150、内折支架130的转动，既实现了对柔性电路板80的隐藏和保护，也不会对转轴机构100的正常转动造成影响、干涉。
需要说明的是，本实施例提供的智能眼镜10可以是基于虚拟现实技术(Virtual Reality，VR)的智能眼镜10，其是一种可以创建和体验虚拟世界的计算机仿真系统，它利用计算机生成一种模拟环境，使用户沉浸到该环境中。虚拟现实技术就是利用现实生活中的数据，通过计算机技术产生的电子信号，将其与各种输出设备结合使其转化为能够让人们感受到的现象，这些现象可以是现实中真真切切的物体，也可以是我们肉眼所看不到的物质，通过三维模型表现出来。
也可以是基于增强现实(Augmented Reality，AR)技术的智能眼镜10，其是一种将虚拟信息与真实世界巧妙融合的技术将虚拟显示的内容在现实实景中叠加的技术。它通过计算机技术生成虚拟的信息，如视觉图像、声音等；然后将虚拟的信息应用到真实的世界。虚拟现 实技术不仅展现了真实世界的信息，而且还可以将虚拟的信息同时显示出来，两种信息相互补充、叠加。
还可以是基于混合现实(Mixed Reality，MR)技术的智能眼镜10，其通过在虚拟环境中引入现实场景信息，在虚拟世界、现实世界和用户之间搭起一个交互反馈的信息回路，以增强用户体验的真实感。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
