本发明提出一种摄像头升降装置，应用于智能终端。
参见图1和图2，本发明实施例中，所述摄像头升降装置包括：
壳体10，所述壳体10形成有容纳腔，且开设有连通所述容纳腔的安装口1511；
摄像头模组30，所述摄像头模组30安装于所述容纳腔内，并邻近所述安装口1511；
驱动模组50，所述驱动模组50安装于所述容纳腔内，且位于所述摄像头模组30背离所述安装口1511的一端，所述驱动模组50包括定子51和动子53，所述定子51连接于所述壳体10，所述动子53连接所述驱动模组50；
所述定子51和所述动子53二者之一包括线圈组件531，二者之另一包括磁体组件511，对所述线圈组件531进行通电，通电的所述线圈组件531在所述磁体组件511产生的磁场中受到安培力作用，所述线圈组件531和所述磁体组件511可进行相对运动，以使所述动子53相对所述定子51进行往复运动，所述动子53驱动所述摄像头模组30至少部分伸出所述安装口1511，或隐藏于所述壳体10内。
本发明技术方案中，摄像头模组30具有拍摄的功能，驱动模组50的定子51和动子53二者之一包括线圈组件531，二者之另一包括磁体组件511，由于线圈组件531在通电的情况下能够在磁体组件511产生的磁场中受到安培力的作用，从而使得线圈组件531能相对磁体组件511进行运动，即，动 子53和定子51之间能够产生相对运动，将定子51连接于壳体10，能使动子53相对定子51进行往复运动。当需要利用该摄像头模组30进行拍照或摄像时，控制所述驱动模组50的动子53相对定子51运动，使摄像头模组30部分伸出于安装口1511，该伸出的部分能够获取外部信息，以实现拍照或摄像的操作；当使用完毕后，控制驱动模组50的动子53相对定子51反向运动，使摄像头模组30隐藏于壳体10内，该摄像头模组30不占用壳体10表面空间，从而使得壳体10表面的空间能够被充分利用，实现全面屏。
驱动模组50位于摄像头模组30背离安装口1511的一端，不仅能节省摄像头模组30侧向的安装空间，且使得驱动模组50沿运动方向将驱动力直接专递至摄像头模组30，使得驱动模组50驱动效率高，节省能耗。
进一步地，本发明技术方案中通过动子53相对定子51做往复运动而组成的直线电机结构，能直接对摄像头模组30进行驱动，无需设置中间的传动机构，使得摄像头升降装置结构简单、运动过程中噪音小，且响应速度块，使用寿命长。
进一步地，所述磁体组件511延伸形成条状，所述线圈组件531套设于所述定子51的外侧，并沿所述磁体组件511的延伸方向往复运动。
线圈组件531形成呈中空的环形结构，磁体组件511穿设于该线圈组件531所围合的区域内，使得动子53对定子51的驱动效果更均匀，动子53的运动过程平稳。可以理解地，还可以将线圈组件531设置于磁体组件511的一侧，通电的线圈组件531也能在磁体组件511产生的磁场内进行往复运动。
将线圈组件531在所述驱动模组50运动方向上的延伸长度设置为大于所述磁体组件511在所述驱动模组50运动方向上的延伸长度；或所述线圈组件531在所述驱动模组50运动方向上的延伸长度与所述磁体组件511在所述驱动模组50运动方向上的延伸长度一致。当线圈组件531相对磁体组件511运动使摄像头模组30缩回于壳体10内时，线圈组件531能将磁体组件511完全罩盖，以节省该驱动模组50的占用空间，从而使得该摄像头升降装置的空间利用率高。
参见图3和图4该实施例中，磁体组件511设于定子51，线圈组件531设于动子53，线圈组件531相对磁体组件511运动，从而带动摄像头模组30运动。由于定子51和动子53两者之间进行相对运动，本发明另一实施例中， 可以将线圈组件531设于定子51，将磁体组件511设于动子53，即，线圈组件531与壳体10相连接，保持线圈组件531与壳体10的相对位置不变，将摄像头模组30连接于磁体组件511，磁体组件511相对线圈组件531运动，从而带动摄像头模组30运动。
所述磁体组件511包括至少两磁铁5111和至少一磁轭5113，所述磁铁5111和所述磁轭5113沿所述磁体组件511的延伸方向间隔设置，相邻两所述磁铁5111的极性相反。
进一步地，参见图5，所述磁体组件511包括三磁铁5111，三磁铁5111沿所述磁体组件511的延伸方向依次排列，相邻两所述磁铁5111的极性相反。三磁铁5111依次排列，使得线圈组件531能延伸磁体组件511的延伸方向运动的距离更长，能够推动摄像头模组30达到指定位置，且驱动效率高。
更进一步地，所述磁体组件511包括多个磁轭5113，每一所述磁铁5111的两端均设有所述磁轭5113。磁轭5113由导磁材料作成，作用是将磁铁5111发散的磁场聚磁到动子53与定子51间的气隙中，从而增强气隙磁场的磁通密度，达到提升线性电机的驱动力的目的。
由于永磁体不易失磁也不易被磁化，能够保证该驱动模组50的工作效率和使用寿命。优选地，所述磁铁5111为永磁体。
若该永磁体在使用过程中磁性流失较大，可以采用轴向充磁的方式对磁铁5111进行充磁，使得该驱动模组50能够保证传动的准确性。
进一步地，磁性组件还包括第一套管(未图示)，该第一套管套设于磁铁5111和磁轭5113所组成的结构的外侧，该第一套管不仅能对磁铁5111和磁轭5113进行保护，还能够为线圈组件531提供导向作用，使得线圈组件531的运动过程更加顺畅。
该第一套管的内壁面与磁铁5111和磁轭5113所组成的结构外形相匹配，且该第一套管的外壁面与线圈组件531的内壁面的形状相匹配，并与线圈组件531的内壁面形成间隙，以使线圈组件531能相对第一套管进行往复运动。
本发明实施例中，磁体组件511的横截面为方形，以使得该驱动模组50能够充分利用容纳腔内部的空间。
继续参见图5，本发明实施例中，所述线圈组件531包括三所述线圈5311，三所述线圈5311均套设于所述磁体组件511的外侧，并沿所述磁体组件511 的延伸方向并列设置，三所述线圈5311可沿所述磁体组件511的延伸方向往复运动，相邻两所述线圈5311中电流的方向相反。
具体可以为将相邻两个线圈5311反向绕制，正接串联；或者相邻两个线圈5311同向绕制，反接串联。
线圈5311的数量也可以为更多或更少，具体根据摄像头模组30的行程需求和容纳空间内尺寸进行选择。
可选地，线圈5311与磁铁5111的数量一致，从而能更充分利用驱动模组50的结构和安装空间。
进一步地，线圈组件531还包括第二套管(未图示)，该第二套管套设于磁体组件511的外侧，线圈5311绕制于第二套管。该第二套管用于固定线圈5311，使得线圈5311能于第二套管上绕制均匀、排列整齐，使得线圈5311各处密度相等，从而提高驱动模组50的使用性能。
进一步地，所述驱动模组50还包括安装座54，所述安装座54固定于所述容纳内，所述定子51背离所述摄像头模组30的一端固定于所述安装座54。
该安装座54具体包括第一侧板和第二侧板，该第一侧板和第二侧板相连接且成夹角设置，第一侧板与壳体10的内表面平行，且通过螺钉固定于壳体10的内表面，第二侧板垂直于第一侧板，定子51背离摄像头模组30的端部固定于第二侧板，该第二侧板能够对驱动模组50进行固定，且延伸至对动子53的端部进行止挡。动子53驱动摄像头模组30运动过程中，动子53相对定子51朝向远离第二侧板方向运动，将摄像头模组30推出至部分伸出安装口1511外侧；动子53相对定子51朝向第二侧板方向运动，直至动子53由该第二侧板止挡，而使摄像头组件缩回于容纳腔内，或摄像头组件部分嵌设于安装口1511，且与壳体10的外表面平齐。
进一步地，驱动模组50还可以设置相配合的导向柱和导向孔。可以将导向柱固定于壳体10或固定于定子51，在动子53上设置导向孔，导向柱配合穿过导向孔，以对动子53的运动进行导向。可以将导向柱的一端固定于安装口1511所在平面，导向柱的另一端固定于安装座54，使得导向柱的轴线与动子53的运动方向一致。该导向柱可以为两个，两导向柱分别位于摄像头模组30的两侧，从而使得驱动模组50和摄像头模组30的运动更加稳定。可以在导向孔内设置滑动轴承，使得驱动模组50和摄像头模组30的运动过程更加 平稳，噪音更小。
本发明实施例中，壳体10包括相对设置的前壳(未图示)和后壳13，以及设于所述前壳和所述后壳13之间的中框15，所述前壳、后壳13和中框15共同围合形成所述容纳腔，所述前壳设有显示屏，所述安装口1511设于所述中框15。
在需要使用摄像头功能时，驱动驱动模组50，使摄像头模组30部分伸出于中框15，不会占用前壳的空间，能够在前壳上能尽可能大的设置显示屏，实现全面屏结构。
中框15包括相对设置的顶壁151和底壁153，以及相对设置的第一侧壁155和第二侧壁157，该顶壁151、第一侧壁155、底壁153和第二侧壁157依次首尾相连，且宽度一致，顶壁151和底壁153的延伸长度小于第一侧壁155和第二侧壁157的延伸长度。可选地，安装口1511开设于顶壁151，摄像头模组30可由安装口1511伸出于顶壁151，或隐藏于壳体10内。
根据设计需要，还可以将安装口1511设置于底壁153、第一侧壁155或第二侧壁157，均在本发明的保护范围内。
容纳腔内还可以设置滑轨(未图示)，摄像头模组30安装于滑轨，并在动子53的驱动下沿滑轨运动，以伸出安装口1511或隐藏于壳体10内，从而更进一步保证摄像头模组30运动的稳定性。该滑轨可以包括用于容纳腔摄像头模组30的容纳槽，也可以仅包括挡柱或挡板，对摄像头模组30的运动进行限位。
本发明实施例中，摄像头模组30与动子53可以通过胶黏剂粘结。具体地，所述摄像头模组30背离所述安装口1511的一端粘贴于所述动子53。将摄像头模组30和动子53通过胶黏剂灌封起来，以使动子53运动过程中能带动摄像头模组30运动，且能起到防震、隔热以及绝缘等目的。
摄像头模组30和动子53的连接结构还可以通过卡扣和卡槽相配合实现。所述摄像头模组30和所述动子53二者之一设有卡扣，二者之另一设有卡槽，所述卡扣卡持于所述卡槽。
可选地，在驱动模组50的动子53上设置卡扣，在摄像头模组30上设置相应的卡槽，将卡扣卡持于卡槽以实现动子53与摄像头模组30的固定连接。该实施例使得驱动模组50可以驱动不同结构的摄像头模组30，无需根据不同 的摄像头模组30制作专用的驱动模组50，只需要在摄像头模组30上制作出相应的卡槽即可，使得驱动模组50与摄像头模组30连接方便，且同一驱动模组50能够适应不同结构的摄像头模组30，节约制作成本。
可选地，所述动子53还包括保护壳533，所述线圈组件531设于所述保护壳533内，所述摄像头模组30包括安装壳31和摄像头(未图示)，所述安装壳31连接于所述壳体10，所述摄像头安装于所述安装壳31，所述保护壳533与所述安装壳31为一体结构，所述动子53通过所述保护壳533驱动所述摄像头模组30运动，以使所述摄像头伸出于所述安装口1511或隐藏于所述壳体10内。
该实施例中，将动子53的保护壳533与摄像头模组30的安装壳31制作为一体结构。在生产过程中，通过一道工序直接制作出一体的保护壳533和安装壳31，在安装过程中，将线圈组件531安装于所述保护壳533内，将摄像头安装于安装壳31内，从而保证线圈组件531运动过程中，能够带动摄像头进行运动，且安装过程简单。
所述容纳腔内安装有主板，所述摄像头升降装置还包括柔性电路板，所述柔性电路板电性连接所述主板和所述摄像头模组30，所述柔性电路板具有折弯部，所述动子53相对所述定子51往复运动过程中，所述摄像头模组30带动所述柔性电路板运动，使所述弯折部伸展或折叠。
摄像头模组30和主板通过该柔性电路板电性导通，由于柔性电路板具有良好的可变形能力，在摄像头模组30的运动过程中，摄像头模组30与主板之间的距离改变，柔性电路板上的弯折部能够进行折叠或拉伸，而不影响其上的导电结构，从而能够保证动子53带动摄像头模组30运动过程中，摄像头模组30和主板之间电性连接的有效性，使得摄像头模组30与主板的电性连接不会在摄像头模组30的频繁运动过程中损坏，提高摄像头升降装置的使用寿命。该折弯部可以为设置于柔性电路板上的多条折痕，折痕的延伸方向与摄像头模组30的运动方向相垂直。
具体地，驱动模组50固定于后壳13的内表面，柔性电路板可以位于驱动模组50与前壳之间，且一端连接摄像头模组30，另一端连接主板。也可以为，柔性电路板具有朝向不同方向延伸的多段式结构，柔性电路板由摄像头模组30的侧面与摄像头模组30进行电连接，并能绕开驱动模组50与主板实 现电连接，在驱动模组50驱动摄像头模组30运动过程中，在摄像头模组30靠近主板运动的过程中，柔性电路板上的弯折部于折痕处进行折叠；在摄像头模组30远离主板运动的过程中，柔性电路板上的弯折部于折痕处进行伸展。
