Description

一种具有可脱卸外置摄像头的拍摄设备保护壳 技术领域
本发明涉及手机附件技术领域，具体涉及一种具有可脱卸外置摄像头的拍摄设备保护壳。
背景技术
手机在最早面世时，仅作为一种可以在较广范围内使用的便携式电话终端使用。随着科技的进步和经济的发展，手机的功能越来越强大，已经成为生活必需品。目前手机分为智能手机和非智能手机，由于智能手机的主频较高，运行速度快，处理程序任务更快速，日常更加方便，所以现在智能手机的市场占有率更高。智能手机是指像个人电脑一样，具有独立的操作系统，独立的运行空间，可以由用户自行安装软件、游戏、导航等第三方服务商提供的程序，并可以通过移动通讯网络来实现无线网络接入手机类型的总称。
智能手机最基本的一个功能就是拍摄功能，如今手机的拍照功能越来越强大、像素越来越高，正逐渐取代一般的家庭相机成为大众首选的拍照工具。但手机上集成的拍照功能由于在设计时，受到手机尺寸和重量的限制，一般只能进行简单的拍摄。但这种传统的定焦手机镜头已经满足不了人们对更高生活品质的追求，于是出现了手机外接摄像头，人们可以根据拍摄需要，随意选择自己需要的特殊镜头，一般特殊镜头包括2X变焦、4X变焦，微距，鱼眼，广角等。
现有手机外置摄像头与手机的固定方式有多种，大多是采用旋转定位 结构，将外置摄像头转动定位在手机壳上。但其定位结构复杂，不仅造价成本高，也拉低消费者的使用体验，常常因为镜头旋转定位结构损坏，外置摄像头与手机内置摄像头不能精确定位，导致整个外置摄像头设备无法正常使用，造成资源浪费。
例如，中国专利文献CN204465641U中公开了一种多镜头转盘手机壳，其在手机壳上设置一个转盘并在转盘上设置若干镜头，由此实现在使用该手机壳时通过旋转转盘即可进行镜头切换的操作。转盘在手机壳上的连接方式为：转盘在靠近手机壳壳体的一面开设不规则凹槽，在凹槽的边沿开设一组圆弧形凹槽，圆弧形凹槽数量和位置与光学镜头数量和位置对应。在手机壳壳体靠近转盘的一面的固定孔上固定设有一伸缩定位杆，伸缩杆的长度小于外壳的长度，弹簧设置伸缩杆底部与外壳底部的内表面之间。
但上述专利，当转动转盘时，伸缩定位杆主体不动，但仍要承受转盘转动时产生的旋转力矩。由此，常常在使用一段时间后，伸缩定位杆开始松动，导致转动不顺利，无法正常定位。

在本发明中，镜头座轴与滑块是用螺丝固定的。
在本发明中，第一阶梯孔和第二阶梯孔分别设置在镜头座及镜头盖的中心位置。
在本发明中，第一弹性件采用复位簧。
本发明技术方案，具有如下优点：
1.在本发明中，通过将镜头座定位在枢转定位元件上与壳本体连接，并沿枢转定位元件轴向设置第一弹性件，使得镜头座在以枢转定位元件为中心转动时，仅需要克服第一定位部与第一定位配合部之间的静摩擦力和第一弹性件的偏压力，而避免对第一弹性元件产生旋转力矩，避免第一弹性件因旋转力矩作用而发生损毁，从而使镜头座转动更加顺滑，使采用本发明中外置摄像头拍摄设备的保护壳使用寿命极大地延长，其结构简单，因此又节约了生产成本，提高了市场占有率。
2.在本发明中，增加镜头盖对镜头座中处于非使用状态的光学镜头加以保护。镜头盖的定位是通过在镜头盖中心设置向内侧延伸的第二阶梯孔，第二阶梯孔置于镜头座的第一阶梯孔内限位，且将第一弹性件置于第二阶梯孔与枢转定位元件的第一防脱结构之间，使得镜头座牢固的定位在枢转定位元件上，且安装结构简单不易损毁。

4.本发明中，枢转定位元件是非转动的中心定位元件。枢转定位元件中的镜头座轴与滑块连接时，采用了异形限位的结构，即在镜头座轴与滑 块上的轴座接触面上设置匹配的轴向平面，限位镜头座轴为非转动中心定位轴。进一步保护了镜头座轴内部设置的第一弹性件，不会产生轴向旋转力矩而发生损毁。
在本发明中，外置摄像头可通过手机保护壳上的滑槽和导轨做左右推移，镜头座可以360度自由旋转，从而达到互换镜头的目的。镜头座在滑轨上有两个定位点，方便切换镜头座在使用位置或非使用位置。同样镜头座360度转动也有定位点，以精准定位每组镜头的位置和手机内置摄像头的位置对准。

实施例1
如图1-3所示，本发明的一种具有可脱卸外置摄像头的拍摄设备保护壳，包括开设有拍摄设备内置摄像头位置孔的壳本体，还包括外置摄像头组，所述外置摄像头组包括：
镜头座21，其上具有第一阶梯孔211，以及若干环绕第一阶梯孔211设置的光学镜头；
枢转定位元件，其两端分别设有第一防脱结构和第二防脱结构，中部设有转动定位部，所述转动定位部位于第一阶梯孔211内，所述第一防脱结构和第二防脱结构分别位于第一阶梯孔211的两端，将镜头座21限位在所述转动定位部上，所述第二防脱结构与壳本体连接；
第一弹性件22，设置在所述第一防脱结构与所述第一阶梯孔211的台阶之间，其偏压力作用在所述镜头座21上；
第一定位结构，包括第一定位部和若干第一定位配合部，所述第一定位部和第一定位配合部设置在所述镜头座21、所述壳本体二者之上，或设置在所述镜头座21、所述第二防脱结构二者之上，所述镜头座21在外力作用下，沿所述枢转定位元件的轴向方向做远离所述壳本体的移动时，克服所述第一弹性件22的弹力，所述第一定位部与对应的所述第一配合定位部脱离结合，所述镜头座21在外力作用下可相对所述壳本体旋转；当所述镜头座21旋转到选定的所述光学镜头与内置摄像头位置孔对准且外力消失时，所述镜头座21在所述第一弹性件22的弹力作用下，使所述第一定位部与对应的所述第一配合定位部对准结合，将所述镜头座21限位在所述壳本体上。
上述方案为本发明的核心方案，通过将镜头座21定位在枢转定位元件上与壳本体连接，并沿枢转定位元件轴向设置第一弹性件22，使得镜头座21在以枢转定位元件为中心转动时，仅需要克服第一定位部与第一定位配合部之间的静摩擦力和第一弹性件22的偏压力，而避免对第一弹性元件产生旋转力矩，避免第一弹性件因旋转力矩作用而发生损毁，从而使镜头座21转动更加顺滑，使采用本发明中外置摄像头拍摄设备的保护壳使用寿命极大地延长，其结构简单，因此又节约了生产成本，提高了市场占有率。
在本发明中，所述拍摄设备为手机。
在本发明中，所述枢转定位元件中包括三部分，分别为限位镜头座为中心转动的转动定位部、分别位于转动定位部上下两端的第一防脱结构和第二防脱结构，所述第一防脱结构和第二防脱结构用来防止镜头座从转动定位部中脱出。具体的，本实施例中枢转定位元件采用了镜头座轴23，其中镜头座轴23的第一端设有凸缘231作为第一防脱结构，中部为转动定位部。在第二防脱结构的上端面设置轴座用于将镜头座轴23的第二端置于其 中限位，并采用螺钉固定连接第二防脱结构和镜头座轴23。第二防脱结构上的轴座沿竖直方向的长度与镜头座轴23的长度依据实际需要进行调整，本实施例中，参看附图3，镜头座轴23的长度大于轴座的长度，这样便于后续安装第二定位部。本实施例中枢转定位元件的结构简单，安装方便。作为变形实施方式，枢转定位元件还可以由螺钉构成，螺帽作为第一防脱结构，螺杆作为转动定位部，与第二防脱结构可以采用螺纹连接的方式。
在本发明中，第二防脱结构可以采用尺寸大于所述镜头座21中的第一阶梯孔211孔径的长条板、圆形板或异形板，板上设有与镜头座轴23连接的连接结构。
在本发明中，第一定位部为设置在第二防脱结构上的定位凸起33，第一配合定位部为设置在镜头座21上的定位孔，且所述定位孔是盲孔。当所述镜头座21在外力作用下，沿所述镜头座轴23的轴向方向做远离所述壳本体的移动时，克服所述第一弹性件22的弹力，定位凸起33与对应的定位孔脱离结合，镜头座21在外力作用下相对所述壳本体及镜头座轴23旋转；当镜头座21旋转到选定的所述光学镜头与内置摄像头位置孔对准时，让外力消失，此时，镜头座21在第一弹性件22的弹力作用下，使定位凸起33与对应的定位孔对准结合，即定位凸起33滑入定位孔内，将镜头座21限位在壳本体上。另外，本实施例中，镜头座21上设有三组光学镜头，相应的，镜头座21上的定位孔也配套设有三个，分别用于定位三组光学镜头与手机内置摄像头的位置。参看附图1，可以看到本实施例中包含三组光学镜头，每组光学镜头分别包括两个独立的光学镜头。
在本发明中，外置摄像头组中还增设镜头盖24，所述镜头盖24具有一向所述镜头盖24内侧延伸的第二阶梯孔241，所述第二阶梯孔241置入镜头座21的第一阶梯孔211内防脱限位，所述镜头座轴23的转动定位部位于第二阶梯孔241内，所述第一弹性件22设置在所述第一防脱结构与所述第二阶梯孔241的台阶211a之间。增加镜头盖24对镜头座23中处于非使 用状态的光学镜头加以保护。镜头盖24的定位是通过在镜头盖24中心设置向内侧延伸的第二阶梯孔241，第二阶梯孔241置于镜头座21的第一阶梯孔211内限位，且将第一弹性件22置于第二阶梯孔241与枢转定位元件的第一防脱结构之间，使得镜头座21牢固的定位在枢转定位元件上，且安装结构简单不易损毁。作为变形实施例，本发明中所述第一弹性件22可采用一个较大尺寸复位压簧直接套装在镜头座轴23上，也可以采用多组小尺寸复位簧均布在镜头座23周围实施。
在本发明中，所述外置摄像头组还可拆卸的连接在所述壳本体上。具体设置结构为：首先将第二防脱结构设置为滑块3，所述滑块3为大体规矩的长条状，且上下边沿上分布四个限位凸起31；在壳本体上设有滑槽122，所述滑槽122的两侧设有导轨，所述滑槽122呈长条状，且上下边沿具有与所述限位凸起31形状相匹配的四个凹槽123；所述滑块3可从所述滑槽122的一端装入或脱出滑槽122内，并沿滑轨往返移动。滑块3上端面设有轴座，镜头座轴23置于轴座内限位，且轴座内设有四个螺钉安装孔，镜头座轴23第一端上也配套设有四个螺纹孔，二者借助螺钉固定连接。镜头座轴23的第一端沿轴线方向设有盲孔232，滑块3上配套设有滑块通孔32，所述盲孔232与所述滑块通孔32相通构成一个安装槽；在安装槽内，设置弹簧35作为第二弹性件，在弹簧35末端安装滚珠34作为第二定位部，相应的在滑槽122槽底上设置两个限位凹槽作为第二配合定位部，其中，第一限位凹槽124用于当外置摄像头组处于拍摄位置时限位，第二限位凹槽125用于当外置摄像头组处于非拍摄位置时限位。另外，所述滑块通孔32的孔径要小于所述滚珠34的直径，以防滚珠34从滑块通孔32中脱出。作为变形实施例，滚珠34还可以采用弹销、或半球形圆凸代替；弹簧35也可采用多组小尺寸压簧组合设置在安装槽内实施。
在本发明中，所述壳本体是复合式结构，包括适于包裹拍摄设备边框的壳软胶11和适于定位外置摄像头组的壳硬胶12，二者采用粘结定位。所 述壳软胶11上成型有第一位置孔111，所述壳硬胶12上成型有第二位置孔121，所述内置摄像头位置孔由所述第一位置孔111、所述第二位置孔121重合组成，所述滑槽122成型在所述壳硬胶12上。所述壳软胶11上对应所述滑槽122的位置还设有与所述第一位置孔111相通的条形孔112。
在本发明中，所述滑块3上的轴座的座槽呈圆形，且沿座槽轴向设有定位平面；所述镜头座轴23沿轴向设有适于与座槽内的定位平面相匹配的定位台面。镜头座轴23与滑块3通过二者之间设置的定位台面可不发生相对转动。
本实施例在具体实施时，参考图1-3，当需要将外置摄像头与手机壳壳本体进行连接时，将滑块3放置在壳本体滑槽122的最右端，并使滑块3四个角上的限位凸起31与滑槽122上的四个凹槽123位置对准，此时滑块的四个限位凸起31落入滑槽122上下两端的导轨内，向左推拉外置摄像头将滑块3限位在导轨内，此时，滚珠34被顶在滑块通孔32内未伸出，弹簧35在盲孔232内处于强压缩状态；继续向左推拉外置摄像头，当滚珠34与第二限位凹槽125位置重合时，滚珠34部分伸出滑块通孔32，并落入第二限位凹槽125内限位，滑块3与滑槽122位置相对固定，此时，外置摄像头处于非拍摄位置。当需要使用外置摄像头进行拍摄时，对外置摄像头施加一定向左的推拉力，滚珠34在推拉力作用下从第二限位凹槽125内脱出并缩回滑块通孔32内，继续向左推拉，当滚珠34与第一限位凹槽124位置重合时，滚珠34部分伸出滑块通孔32，并落入第一限位凹槽124内限位，滑块3与滑槽122位置相对固定，此时，外置摄像头处于拍摄位置。
在选择需要的光学镜头组时，对镜头座21施加一定的旋转力，镜头座21以镜头盖24的第二阶梯孔为转动中心转动，镜头座21上的定位孔逐渐与滑块3上的定位凸起33脱离，且镜头座21带动镜头盖24沿镜头座轴23轴向做远离壳本体的运动；继续旋转镜头座21，当镜头座21上的下一个定位孔与滑块3上的定位凸起33位置对准时，在第一弹性件22也就是复位 簧的作用下，定位孔与定位凸起33对准结合，如此往复，实现光学镜头组的选择和定位。
本实施例中镜头盖24可旋转，也可通过第二阶梯孔的台阶211a与滑块3上的轴座固定连接。
实施例2
本实施例2与实施例1不同之处在于，所述壳本体是一体式结构。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
