Description

一种便携微观成像装置 [技术领域]
本发明属于微观成像领域，具体涉及一种便携微观成像装置。
[背景技术]
显微镜可以对微观结构进行观测。传统显微镜由物镜和目镜组成，用于将微观结构放大后呈现到人眼的明视距离处。数码显微镜使用面阵光电探测器取代人眼进行探测，可以将图像记录成数字图像文件，为信号采集带来了便利。
显微镜的尺寸通常较大，以放置在桌面上的台式显微镜形式最为常见。小型化的便携式的数码显微镜以及与手机配套使用的手机显微镜解决了显微镜的便携性问题，但是仍存在一定的局限性，表现为需要外置光源进行照明，当照明和显微镜本体结合到一起时，还需要包含电池，导致整体结构较大。虽然申请人的在先专利CN108681188A提出了一定的改进方案，但是实际使用用发现，采用其导光反射端和镜头安装孔等结构，当手机的摄像头和照明器距离较近时，通过反射端导向安装孔处的照明光始终有部分不可避免地直接照射入镜头中且比例较高，而不是经显微对象反射到镜头中，导致成像不均匀，成像质量有待提高；另外，镜体的可拆卸安装方式，针对于镜头突出手机机体的机型等，均有待进一步改进。
[发明内容]
针对现有技术以上缺陷或改进需求中的至少一种，本发明提供了一种便携微观成像装置，通过结构的重新优化设计，使得成像装置小巧、轻便、方便、易用、放大倍率大，且针对不同型号的便携设备适应性强，成像质量进一步提高，特别适合作为手机等可移动电子成像设备的增强成像模块。
为实现上述目的，按照本发明的一个方面，提供了一种便携微观成像装置，其可拆卸地连接到具有摄像头和照明器的便携式成像设备，该便携微观成像装置包括镜头和镜体，所述镜头至少部分安装在所述镜体的安装孔中；所述镜头包括透镜、镜头封装；所述镜头正对安装于所述便携式成像设备的摄像头处；
所述镜体由透明或半透明的固体材料制成，其长度方向上的厚度均匀；所述镜体的正面的外表面局部设置有独立的镜面反射层或漫反射层、覆盖所述照明器，所述镜面反射层或漫反射层采用不透光材料制成，与所述镜体的正面外周边之间形成封闭环形透光 圈；

[具体实施方式]
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。此外，下面所描述的本发明各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以相互组合。下面结合具体实施方式对本发明进一步详细说明。
如图1-3所示，本发明的一种便携微观成像装置，其可拆卸地连接到具有摄像头31和照明器32的便携式成像设备3，该便携式成像设备3例如是手机、平板等，其具有摄像头31和照明器32，照明器32例如是闪光灯、补光灯等。
该便携微观成像装置包括镜头1和镜体2，所述镜头1至少部分安装在所述镜体2的安装孔21中；所述镜头1包括透镜、镜头封装；镜头1中的透镜由球面透镜或非球面透镜组成，可以是单片透镜也可以是多片组成透镜组。优选的，镜头1中包含非球面透镜，且由多片透镜组成透镜组。所述镜头封装为镜头1提供机械封装结构。如图3所示，所述镜头1正对安装于所述便携式成像设备3的摄像头31处。
如图1-3所示，所述镜体2由透明或半透明的固体材料制成，其长度方向上的厚度均匀；镜体2同时起到机械结构和光导的作用。镜体2的光导功能是指将便携式成像设备3上的照明器32(例如闪光灯)发出的光导入到镜头1要成像的物体上。所述镜体2的正面20b的外表面局部设置有独立的镜面反射层或漫反射层、覆盖所述照明器32，所述镜面反射层或漫反射层采用不透光材料制成，与所述镜体2的正面20b外周边之间形成封闭环形透光圈。所述镜体2的正面20b的所述镜面反射层或漫反射层的外侧设置文字和/或图案标识。本发明的便携微观成像装置，通过镜体正面反射层与镜体边缘之 间构造的封闭环形透光圈，在使用时导光腔内的照明光从透光圈缝隙中透出，即不损失大量的照明光，又利用照明器营造的光圈使得成像装置产品明亮美观、生动鲜活，具有高科技感，对消费者和旁观者极具吸引力。
如图4-5所示，所述镜体2的安装孔21在镜体的正面20b上的开口尺寸大于所述镜头1的尺寸。
如图4所示，所述镜体2的安装孔21包括一个锥孔211，该锥孔211的最小直径等于所述镜头1的直径，该锥孔211的锥面为透明面或半透明面。
或者如图5所示，所述镜体2的安装孔21包括一个圆柱形沉孔212，该圆柱形沉孔212的直径大于所述镜头1的直径，该圆柱形沉孔212的表面为透明面或半透明面。
如图6所示，为提供均匀明亮的照明，所述镜体2的厚度t(正反面法线方向的厚度)大于或等于3.5mm，同时镜体的正面20b到镜头物方端面10b的距离不超出镜头1的工作距离w，所述镜头的工作距离是指镜头配合所述便携式成像设备工作时能够清晰成像的区域到镜头物方端面10b的距离。本发明的便携微观成像装置，通过反复摸索试验，提出了对镜体厚度和镜头安装位置的具体限制，可以使得导光和成像效果保持在最佳状态。
如图7-8所示，所述镜体2的背面20a以粘贴或吸附的方式与所述便携式成像设备3的安装面可拆卸地连接，且在远离所述镜头1的一端设置有选配件安装槽，用于可拆卸地扩展安装选配件。
如图7所示，所述镜体2的背面20a设置有粘贴层41，所述粘贴层41的外侧用于与所述便携式成像设备3的安装面的重复性粘贴连接，所述粘贴层41对应所述镜头1的安装孔21处设置有开孔。
如图7所示，所述粘贴层41为围绕所述镜头1的环形，所述镜体2的背面20a上对应开设有环形凹槽，所述粘贴层41的部分厚度埋入环形凹槽中，且所述粘贴层41的内侧粘贴连接于环形凹槽和/或卡嵌连接于环形凹槽，所述粘贴层41不覆盖所述便携式成像设备3的照明器32在所述镜体的背面20a的投影区域。
或者如图8所示，所述粘贴层41为长条形，所述粘贴层41的内侧连接于所述镜体的背面20a，所述粘贴层41覆盖所述便携式成像设备3的照明器32在所述镜体的背面20a的投影区域，所述粘贴层41采用透明或半透明材料制成。
所述镜体2的背面20a设置有吸盘(未示出)，所述吸盘的外侧用于与所述便携式 成像设备3的安装面吸附连接，所述吸盘对应所述镜头1的安装孔21处设置有开孔。
所述吸盘为围绕所述镜头1的环形，所述镜体2的背面20a上对应开设有环形凹槽，所述吸盘的部分厚度埋入环形凹槽中，且所述吸盘的内侧连接于环形凹槽，所述吸盘不覆盖所述便携式成像设备3的照明器32在所述镜体的背面20a的投影区域；
或者，所述吸盘为长条形，所述吸盘的内侧连接于所述镜体的背面20a，所述吸盘覆盖所述便携式成像设备3的照明器32在所述镜体的背面20a的投影区域，所述吸盘采用透明或半透明材料制成。
所述镜体也可通过夹持方式与所述便携式成像设备连接。夹持所用夹具可以为夹子，也可以为手机壳，其目的是与便携式成像设备固定，所述夹具与镜体可以为永久式固定连接，也可以是可拆卸式。所述夹具与镜体的固定为可拆卸式时，所述夹具和镜体通过卡扣、螺纹配合、磁铁等方式固定。
与传统的夹具相比，本发明的便携微观成像装置中，镜体的背面以粘贴或吸附的方式与便携式成像设备的安装面可拆卸地连接，通过多种方案的粘贴层或吸盘构造设计，满足了不同型号和规格的便携式成像设备的镜头和照明器对距离和位置的适应性需求，提高了通用性和适应性。
如图9-10所示，所述选配件为脚垫5，所述安装槽为脚垫安装槽，所述脚垫5的部分厚度埋入脚垫安装槽中，且所述脚垫5的内侧可重复性粘贴连接于环形凹槽和/或卡嵌连接于脚垫安装槽中。优选的，所述脚垫为类似硅胶的柔软弹性材料。本发明的便携微观成像装置，还提供了选配件安装槽，可以扩展安装选配件；特别是便携式成像设备的摄像头突出于便携式成像设备的表面时，通过安装选配的脚垫，在镜体和便携式成像设备之间提供支撑，因为此时安装面仅有在镜头附近与便携式成像设备有接触，而安装面的其他位置悬空，而使用脚垫可使镜体在便携式成像设备上安装后更稳定，使用更方便。
本发明的一种便携微观成像装置，通过结构的重新优化设计，使得成像装置小巧、轻便、方便、易用、放大倍率大，且针对不同型号的便携设备适应性强，成像质量进一步提高，特别适合作为手机等可移动电子成像设备的增强成像模块。
本发明的便携微观成像装置，无需设置自身独立光源，通过构造镜体的导光腔体，特别是镜体正面反射层和安装孔的独特构造，无需设置端部导光反射端，即可将便携式 成像设备所带的光源经反射、折射和散射，在镜头附近形成照明光，从而既满足了照明需求，又缩小了成像装置的体积，实现了便携性，同时避免了安装孔处的照明光直接射入镜头，成像均匀，成像质量进一步提高。
本发明的便携微观成像装置体积缩小后，镜头的焦距较小，放大倍率更大，可用于微距成像。
本领域的技术人员容易理解，以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
