具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请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申请，并不用于限定本申请。
相关技术中，镜筒内的镜头在进行组装时，一般都是采用逐层重叠、按特定顺序整体安装的方式。在对液体镜头进行安装时，它需要与传统镜头共同安装，而无法进行单独安装，安装使用极为不便。另外，镜筒内各光学元件由于按顺序安装，彼此之间为了满足成像需要从而在安装时就应满足成像条件。某一个元件的位置发生变化或者安装位置不准确就会导致其他元件相应地可能安装不准确，具有牵一发动而全身的特性，导致后续更新、更换时工序复杂，维护的成本较高。
请参阅图1至图4，为了解决上述技术问题，本申请实施例提出一种镜筒110，该镜筒110包括第一筒体111、连接支架112以及第二筒体113。其中，第一筒体111具有用于安装光学元件的第一安装区1111，连接支架具有用于安装光学元件的容纳区1124，第二筒体113具有用于安装光学元件的第二安装区1131。同时，第二筒体113的光轴114与第一筒体111的光轴114重合，那么，安装于第一筒体111中的光学元件与安装于第二筒体113中的光学元件的光轴114自然也重合，有利于第一筒体111与第二筒体113中的光学元件配合成像。
需要说明的是，第一安装区1111、容纳区1124以及第二安装区1131均是在镜筒110内部根据功能的不同而人为划分出的区域，它们的大小、形状等均没有具体的限定，且它们可能随着镜筒110的使用场景和使用方式的改变而互相切换，因此它们之间并不存在明显的边界。而光轴114是人为规定的虚拟轴线，而并不 是存在于镜筒110中的某个实体。可以理解的是，光学器件安装到镜筒110中时，应使光学器件的光轴114与镜筒110的光轴114重合以达到较好的光学效果。
具体地，连接支架112包括连接板1121以及两个侧壁板1122。该连接板1121具有透光通孔1123，连接板1121的一个表面连接第一筒体111的像侧端，且透光通孔1123的孔壁连接第一筒体111的内周壁。即连接支架112通过连接板1121与第一筒体111连接起来，并且，连接板1121上的透光通孔1123将第第一筒体111的第一安装区1111与连接支架112的容纳区1124连通。这样，经过第一安装区1111的光线就可以透过该透光通孔1123进入到容纳区1124内，便于镜筒110内的不同光学元件配合成像。
而两个侧壁板1122连接连接板1121的背离第一筒体111的表面，且两个侧壁板1122相对设置于透光通孔1123的两侧，第二筒体113的物侧端连接两个侧壁板1122。即连接支架112通过侧壁板1122与第二筒体113连接起来，并且，由于两个侧壁板1122相对设置于透光通孔1123的两侧，也就是说两个侧壁板1122之间具有一定的间距，那么，连接支架112的容纳区1124与第二筒体的第二安装区1131同样也被连接起来。这样，镜筒110内的第一安装区1111、容纳区1124与第二安装区1131均连通，在将镜筒110安装到镜头中进行成像时，由镜筒110的物侧端入射的光线依次穿过第一筒体111的第一安装区1111、连接板1121上的透光通孔1123、连接支架112的容纳区1124、第二筒体113内的第二安装区1131，最后照射到镜筒110的像侧端。
与此同时，由于两个侧壁板1122相对设置于透光通孔1123的两侧，即两个侧壁板1122之间具有一定的间距，那么，在镜筒110的外部，两个侧壁板1122同向的一端与连接板1121以及第二筒体113共同限定出第一插接槽115，且该第一插接槽115与容纳区1124连通。第一插接槽115是容纳区1124与外部的连通口，需要安装到容纳区1124内的光学元件可以由镜筒110的外部，逐步穿过第一插接槽115，进而进入到容纳区1124内，而不需要经过第一筒体111或第二筒体113，也就不会对第一安装区1111与第二安装区1131内的光学元件带来影响或干扰。此处，光学元件的安装可以是手动进行的，也可以是借助动力装置自动进行的。这样，第一筒体111、连接支架112以及第二筒体113内的各光学元件就可以分别在各自的区域内独立安装，互不干扰，安装方便，效率高。并且，各 光学元件与镜筒110之间的安装和固定相对独立，即使某一元件的安装和固定发生变化导致无法准确有效地成像，在后续更换时无需移动甚至破坏其它光学元件，只需移动或更换相应的元件部分，不仅大大减少简化了工序步骤，也极大地降低了成本。
通过调整连接板1121与两个侧壁板1122之间的位置关系，可以改变容纳区1124的容积。例如，将两个侧壁板1122分别向远离容纳区1124中心的方向移动，同时，调整连接板1121的尺寸以使连接板1121与两个侧壁板1122仍然保持连接关系。这样，连接板1121与侧壁板1122之间围设处的空间就会增大，起到了扩大容纳区1124的作用，使连接支架112能够容纳更大尺寸的光学元件，提升了镜筒110的适用场景范围。相反地，当连接支架112内需要容纳的光学元件的尺寸较小时，将两个侧壁板1122分别向靠近容纳区1124中心的方向移动，同时，调整连接板1121的尺寸以使连接板1121与两个侧壁板1122仍然保持连接关系。这样，缩小了容纳区1124的容积，也就减小了镜筒110的尺寸，降低了其加工难度及加工成本。
当光学元件穿过第一插接槽115并设置于容纳区1124时，光学元件可以依靠第一插接槽115对它的支承力来保持平衡和稳定(当然，在其它实施例中，还可以由其它部件来对光学元件进行支承)。为了将光学元件牢靠地固定起来，可以在镜筒110的外侧壁上靠近第一插接槽115的位置设置凸缘部，该凸缘部具有由镜筒110的外侧壁向背离容纳区1124的方向延伸形成的承载面，光学元件就可以通过粘接或其它类似方式与该承载面固定。当镜筒110的筒壁足够厚时，还可以将第一插接槽115的底壁作为承载面来对光学元件进行固定，此时就不再需要依靠凸缘部来对光学元件进行固定了。当需要拆卸取出光学元件时，只需沿着光学元件安装时相反的路径，就可以由第一插接槽115位置处将光学元件取出。
在一个实施例中，两个侧壁板1122的同向的另一端与连接板1121以及第二筒体113共同限定出第二插接槽116。类似地，由于两个侧壁板1122相对设置于透光通孔1123的两侧，即两个侧壁板1122之间具有一定的间距，那么，在镜筒110的外部的另一侧，两个侧壁板1122同向的另一端与连接板1121以及第二筒体113共同限定出第二插接槽116，该第二插接槽116与容纳区1124连通，且第二插接槽116的中心与第一插接槽115的中心的连线与镜筒110内的光轴114相 交。这样，随着光学元件在安装过程中深入到容纳区1124内，光学元件的一端可以承载于第二插接槽116上。类似的，还可以在镜筒110的外侧壁上靠近第二插接槽116的位置设置凸缘部，该凸缘部具有由镜筒110的外侧壁向背离容纳区1124的方向延伸形成的承载面，光学元件就可以通过粘接或其它类似方式与该承载面固定。此时，光学元件的两端分别承载于第一插接槽115以及第二插接槽116上，能够保持平衡和稳定。当需要拆卸光学元件时，既可以沿着光学元件安装时相反的路径，由第一插接槽115位置处将光学元件取出，还可以沿着第二插接槽116的中心与光轴114的连线这条路径，由第二插接槽116位置处将光学元件取出。此时，第一插接槽115与第二插接槽116分别起到了安装入口与拆卸出口的作用，安装与拆卸作业更加灵活。
由于第一插接槽115及第二插接槽116均是由两个侧壁板1122、连接板1121以及第二筒体113共同限定出的，所以第一插接槽115与第二插接槽116分别位于一个穿过镜筒110光轴114的平面的相对两侧，也就是说第二插接槽116的中心和第一插接槽115的中心的连线与镜筒110内的光轴114相交，此处的中心是指插接槽的形心。需要说明的是，由于光学元件的两端可以分别被固定在第一插接槽115与第二插接槽116上的不同位置处，即使第二插接槽116的中心和第一插接槽115的中心的连线不与镜筒110内的光轴114垂直，光学元件也可以被固定在与镜筒110内的光轴114垂直的状态，不至影响光学元件的正常使用。例如，沿平行于镜筒110的光轴114的方向，第一插接槽115的中心比第二插接槽116的中心更靠近镜筒110的物侧端，此时，第二插接槽116的中心和第一插接槽115的中心的连线不与镜筒110内的光轴114垂直，但只需将光学元件固定在第二插接槽116内更靠近镜筒110物侧端的位置上，即可弥补第一插接槽115的中心与第二插接槽116的中心离镜筒110物侧端的差距。
而当第二插接槽116的中心和第一插接槽115的中心的连线与镜筒110内的光轴114垂直时，光学元件的两端可以分别被固定在第一插接槽115与第二插接槽116上对应的位置处，如两端分别被固定在第一插接槽115与第二插接槽116的底壁上即可，便于实际操作。
镜筒110包括位于物侧的入光口117。如本领域技术人员所熟知的，物侧是镜筒110的靠近被拍摄物的一侧，与之相对的，像侧是镜筒110的远离被拍摄物 的一侧。位于物侧的被拍摄物所反射的光线需要进入到镜筒110中才能被镜筒110中的光学元件感应到。因此，镜筒110的物侧开设有入光口117。调节该入光口117的大小，即可改变镜筒110中的入光量。在一个实施例中，镜筒110内的第一安装区1111与容纳区1124的排布方式为：沿平行于镜筒110内的光轴114的方向，第一安装区1111位于容纳区1124以及入光口117之间。即由镜筒110的物侧至像侧方向，依次排列的是镜筒110的入光口117、第一安装区1111以及容纳区1124，此时，由入光口117进入镜筒110的光线先穿过第一安装区1111内的光学元件，再穿过容纳区1124内的光学元件。在其它的实施例中，第一安装区1111与容纳区1124的排布顺序可以有所不同，此时由入光口117进入镜筒110的光线穿过不同光学元件的顺序也会有所不同。
而第二安装区1131与第一安装区1111以及容纳区1124之间的排布关系可以是：沿平行于镜筒110内的光轴114的方向，容纳区1124位于第一安装区1111以及第二安装区1131之间。即由镜筒110的物侧至像侧方向，依次分布的是第一安装区1111、容纳区1124与第二安装区1131，此时，由入光口117进入镜筒110的光线先穿过第一安装区1111内的光学元件，再穿过容纳区1124内的光学元件，随后穿过第二安装区1131内的光学元件。在其它的实施例中，这三个区域的排布顺序可以有所不同，此时由入光口117进入镜筒110的光线穿过不同光学元件的顺序也会有所不同。为了容纳更多数量的光学元件，镜筒110内还可以被分为更多的安装区域。此时各安装区域的排布方式与本实施例中的类似，可以类推得出。
为了节省镜筒110内的空间以缩减镜筒110的整体尺寸，同时也为了使镜筒110具有一定的外观辨识度和吸引力，第一筒体111的垂直于自身的光轴114的直径为第一直径，第二筒体113的垂直于自身的光轴114的直径为第二直径，第一直径小于第二直径。即沿平行于光轴114的方向，由第一筒体111到连接支架112再到第二筒体113，它们的尺寸逐渐增大。此时，连接支架112在尺寸互不相同的第一筒体111与第二筒体113之间起到了过渡作用，由于连接支架112的形状可以是不同于第一筒体111以及第二筒体113的筒状之外的其它任意形状，相较于直径依次变化的筒状而言，连接支架112的加工更加简单方便，成本更低。并且，无论第一直径与第二直径之间的差值有多大，连接支架112都可以很好地 连接第一筒体111与第二筒体113，使整个镜筒110的结构更加稳定。
请参阅图5至图6，本申请实施例的第二个方面提出一种镜头100，该镜头100包括如以上实施例中所述的镜筒110、第一镜片组120、液体镜头模组130以及第二镜片组140。其中，第一镜片组120包括至少一个镜片，第一镜片组120设置于第一安装区1111。液体镜头模组130设置于容纳区1124。第二镜片组140包括至少一个镜片，第二镜片组140设置于第二安装区1131。该镜头100具有第一镜片组120、液体镜头模组130以及第二镜片组140，因此，与之对应的，镜头100中镜筒110的结构包括用于容纳第一镜片组120的第一安装区1111、用于容纳液体镜头模组130的容纳区1124以及用于容纳第二镜片组140的第二安装区1131。当镜头100中还需要有更多的镜片组时，只需要对应采用具有更多安装区的镜筒110即可。
需要说明的是，第一镜片组120以及第二镜片组140中的镜片可以是本领域中常见的采用玻璃或树脂材料制作的镜片，该镜片按照其外形、功能的不同可以分为凸透镜、凹透镜等。当第一镜片组120或第二镜片组140包括多个镜片时，各镜片的种类、形状、大小等可以完全相同，可以部分相同，也可以互不相同。各镜片可以依次层叠安装设置在相应的安装区域内，以共同配合完成镜头100的成像作业。
采用本实施例中的镜头100，镜头100中的液体镜头模组130可以穿过第一插接槽115并设置于容纳区1124，而不再需要与第一镜片组120、第二镜片组140共同安装，安装使用方便快捷。并且，镜头100内的镜片组以及其它可能存在的光学元件与镜筒110本体之间的安装和固定相对独立，即使某一元件的安装和固定发生变化导致无法准确有效地成像，在后续更换时无需移动甚至破坏其它光学元件，只需移动或更换相应的元件部分，不仅大大减少简化了工序步骤，也极大地降低了成本。
请参阅图7至图11，本申请实施例的第四个方面提出一种摄像模组10，该摄像模组10包括如上任一实施例所述的镜头100以及感光芯片200。该感光芯片200用于感应穿过镜头100的光线，且对光线进行成像处理。
液体镜头模组130包括液体镜头131以及镜头支架132。液体镜头131的结构及其使用时的变焦原理如下：液体镜头131包括密闭腔体以及充满该密闭腔体 的导电流体和绝缘流体，该导电流体和该绝缘流体互不相溶并由彼此之间的界面隔开，该导电流体和该绝缘流体的折射率不同。液体镜头131受电极组通电时，其内部的导电流体产生电润湿效应而改变界面与密闭腔体的侧壁的接触角，继而改变界面的形状，以调整光线传播方向，适应调焦或防抖的需要。因此，液体镜头131在安装时需要与电极组或类似的元件电性连接。因此，为了维持液体镜头131在使用时的稳定性和紧密固定性，需要先将液体镜头131安装于镜头支架132上并与镜头支架132电性连接。在一个实施例中，镜头支架132包括第二导线，液体镜头131安装于镜头支架132且与第二导线电连接。随后还需将镜头支架132与电力元件电性连接以维持液体镜头131的正常工作状态，该摄像模组10还包括导线支架300，导线支架300包括第一导线。其中，镜筒110安装于导线支架300，且第二导线与第一导线电连接。这样，就在保证了液体镜头131能够正常工作的前提下，经第二导线、镜头支架132、第一导线、导线支架300最终连接到镜筒110上。
当液体镜头模组130由第一插接槽115安装至容纳区1124后，为了使液体镜头模组130能够具有更好的光学性能，需要对液体镜头模组130进行定位，使液体镜头131的光轴114与镜筒110的光轴114重合。因此，在一个实施例中，侧壁板1122上在远离第一插接槽115的一端设有阻挡块。液体镜头模组130中的镜头支架132带着液体镜头131由第一插接槽115进入到容纳区1124的过程中，阻挡块可阻挡镜头支架132的运动，使得液体镜头模组130停留在特定位置，而当液体镜头131处在此位置时，液体镜头131的光轴114与第一镜片组120的光轴114重合。由此，就可以通过该阻挡块的设置来对液体镜头模组130在容纳区1124内的位置进行定位，使液体镜头131的光轴114与第一镜片组120的光轴114重合，从而使液体镜头模组130能够具有更好的光学性能。
可以理解的使，在其它的实施例中，还可以采用其它多种不同的方式来对液体镜头模组130进行定位，以使液体镜头模组130能够具有更好的光学性能。例如，镜头支架132上设有第一磁吸部，连接支架112内朝向容纳区1124设有第二磁吸部。液体镜头模组130中的镜头支架132带着液体镜头131由第一插接槽115进入到容纳区1124的过程中，第一磁吸部与第二磁吸部之间会由于磁力作用吸合到一起，从而给镜头支架132施加了一个阻力使其停留在特定位置，而当液 体镜头131处在此位置时，液体镜头131的光轴114与第一镜片组120的光轴114重合。由此，就可以通过该第一磁吸部以及第二磁吸部的设置来对液体镜头模组130在容纳区1124内的位置进行定位，使液体镜头131的光轴114与第一镜片组120的光轴114重合，从而使液体镜头模组130能够具有更好的光学性能。
需要说明的是，由于此处是靠第一磁吸部以及第二磁吸部之间的吸合作用实现定位的，因此，第一磁吸部在镜头支架132上的位置、第二磁吸部在连接支架112上的位置均没有特别限制，可以有多种选择，只需要第一磁吸部与第二磁吸部处在相应的位置处即可。例如，第一磁吸部在镜头支架132上位于靠近第一插接槽115的某位置处，相应地，第二磁吸部在连接支架112上位于远离***第一插接槽115的一端的某位置处，这样，第一磁吸部与第二磁吸部吸合时，就可以对液体镜头模组130进行定位，使液体镜头131的光轴114与镜筒110的光轴114重合。同理，第一磁吸部在镜头支架132上的位置、第二磁吸部在连接支架112上的位置还有其它多种选择。
该摄像模组10还包括滤光片400，滤光片400用于对照射向感光芯片200的光线进行滤光处理。滤光片400可以选取投射过的光线的波段范围，其原理是隔绝某一波段的光线，而透过其余波段的光线，通常采用透明的光学材料如玻璃或合成树脂来制作。在摄像模组10中加入滤光片400，可以隔绝某种颜色干扰，使成像效果更加纯净。其中，镜头支架132具有开口部1321，滤光片400连接于镜头支架132的背离液体镜头131的表面，且滤光片400覆盖该开口部1321。这样，滤光片400就处在摄像模组中液体镜头131与镜头支架132之间位置处。穿过液体镜头131的光线依次穿过镜头支架132的开口部1321、滤光片400后最终照射至感光芯片200的表面。
进一步地，滤光片400以及开口部1321共同限定出收容腔，收容腔用于容纳液体镜头131，且液体镜头131由滤光片400承载。通过将液体镜头131收容于收容腔内，可以节省液体镜头131所占用的空间，以减小整个摄像模组10的尺寸。
由于液体镜头模组130在安装完成后是设置在容纳区1124内的，则镜头支架132同样会位于容纳区1124之内，此时，为了在一定程度上消除由于镜筒110的震动而引起的液体镜头131的晃动，在一个实施例中，镜头支架132还包括连 接部1322，镜头支架132配置成设置于容纳区1124后，连接部1322伸出容纳区1124而与导线支架300连接，通过连接部1322实现了容纳区1124内外之间的支撑和传递，将液体镜头131与外部的导线支架300连接，就可以在一定程度上减轻由于镜筒110的震动而对液体镜头131造成的影响。连接部1322的大小和形状不限，但为了更好地实现对镜头支架132的支撑作用，连接部1322可以是在镜头100的两端凸出设置的，且凸出的方向垂直于光轴114。
由于镜头支架132安装在容纳区1124内，而容纳区1124仅在第一插接槽115与第二插接槽116位置处开口与外界连通，因此，镜头支架132上的连接部1322可以由插接槽位置处伸出以便与导线支架300连接。与此同时，考虑到对镜头支架132的支撑稳定性，连接部1322应分别由两边的第一插接槽115与第二插接槽116处伸出。故在一个实施例中，镜头支架132包括两个连接部1322，其中一个连接部1322伸出第一插接槽115而与导线支架300的一端连接，另一个连接部1322伸出第二插接槽116而与导线支架300的另一端连接。这样，两个连接部1322分别由容纳区1124两端的开口处伸出而与导线支架300连接，对镜头支架132的支撑更加平稳、牢固。
当镜头支架132被安装到由连接支架112所限定出的容纳区1124中之后，镜头支架132既可以完全与镜筒110中的连接支架112固定连接，而不与镜筒110外的导线支架300相连；镜头支架132也可以完全与镜筒110外的导线支架300相连，而不与镜筒110固定连接。由于镜筒110外的导线支架300的结构稳定性更强，更不易收到外界影响而发生震动，从而使液体镜头131的工作状态更加稳定不受影响。因此，在一个实施例中，镜头支架132通过两个连接部1322而由导线支架300支撑，以使镜头支架132悬空设置于容纳区1124。即镜头支架132完全与导线支架300连接、支撑，而与镜筒110上的连接支架112没有物理接触。这样，当镜筒110受外力影响发生震动时不会带动液体镜头131震动，液体镜头131工作时的稳定性更佳。
电性连接所需要用到的导线有多种形式，传统的金属线所制成的导线可能会由于长度使用不当造成摄像模组10内出现杂乱感引起零部件的不方便拆装或更换，还可能会导致镜头100前出现导线的黑影影响成像质量。因此，在一个实施例中，第一导线包括第一电性体310以及第二电性体320，第一电性体310靠近 第一插接槽115设置，第二电性体320靠近第二插接槽116设置。第二导线包括第三电性体1323以及第四电性体1324，第三电性体1323伸出第一插接槽115而与第一电性体310电连接，第四电性体1324伸出第二插接槽116而与第二电性体320电连接。本实施例中的导线均采用两两相连的电性体的形式，不会造成摄像模组10内出现杂乱感，零部件的拆装更换方便。并且电性体还不会出现在镜头100前引起黑影影响成像质量。
镜头支架132上的第二导线采用了电性体的形式后，镜头支架132采用第三电性体1323以及第四电性体1324与导线支架300电性连接。而恰好镜头支架132上还设有用于与导线支架300固定支撑的连接部1322，此时，若能将第三电性体1323以及第四电性体1324与连接部1322合二为一，则可以减少摄像模组10内的零部件数量，节约了成本的同时也可以降低零部件出现故障的概率。因此，在一个实施例中，第三电性体1323以及第四电性体1324均用作连接部1322。第三电性体1323伸出第一插接槽115而与第一电性体310电连接，第四电性体1324伸出第二插接槽116而与第二电性体320电连接的同时，第三电性体1323以及第四电性体1324还作为连接部1322而与导线支架300连接支撑。
摄像模组10还包括电路板500以及保护支架600，该电路板500包括芯片安装区510，感光芯片200安装于芯片安装区510且与电路板500电连接，电路板500将感光芯片200上由光信号生成的电信号传递至摄像模组10的其它部件或组件以配合实现成像功能。该保护支架600连接于电路板500，且绕芯片安装区510布置。其中，导线支架300连接于保护支架600的背离电路板500的端部，且第一导线朝靠近电路板500的方向延伸至与电路板500电连接。至此，电路板500、保护支架600、导线支架300与镜头支架132均通过导线电连接串接起来。摄像模组10中的控制单元可随时发出指令控制液体镜头131作出变焦动作，实现摄像模组10中镜头100的变焦功能。
采用本实施例的摄像模组10，摄像模组10中的液体镜头模组130可以穿过第一插接槽115并设置于容纳区1124，而不再需要与第一镜片组120、第二镜片组140共同安装，安装使用方便快捷。并且，摄像模组10内的镜片组以及其它可能存在的光学元件与镜筒110本体之间的安装和固定相对独立，即使某一元件的安装和固定发生变化导致无法准确有效地成像，在后续更换时无需移动甚至破 坏其它光学元件，只需移动或更换相应的元件部分，不仅大大减少简化了工序步骤，也极大地降低了成本。
本申请实施例的第四个方面提出一种电子设备，该电子设备包括如上任一实施例所述的摄像模组10。电子设备可以是手机、平板电脑、笔记本电脑、个人数位助理、智能手环、智能手表等穿戴式设备中利用摄像模组10来实现成像功能的任意一种。
采用本实施例的电子设备，电子设备中的液体镜头模组130可以穿过第一插接槽115并设置于容纳区1124，而不再需要与第一镜片组120、第二镜片组140共同安装，安装使用方便快捷。并且，电子设备内的镜片组以及其它可能存在的光学元件与镜筒110本体之间的安装和固定相对独立，即使某一元件的安装和固定发生变化导致无法准确有效地成像，在后续更换时无需移动甚至破坏其它光学元件，只需移动或更换相应的元件部分，不仅大大减少简化了工序步骤，也极大地降低了成本。
