 本发明的实施方式
下面结合附图和实施方式对本发明作进一步说明。
需要说明的是，本发明实施例中所有方向性指示（诸如上、下、内、外、顶部、底部……）仅用于解释在某一特定姿态（如附图所示）下各部件之间的相对位置关系等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
还需要说明的是，当元件被称为“固定于”或“设置于”另一个元件上时，该元件可以直接在另一个元件上或者可能同时存在居中元件。当一个元件被称为“连接”另一个元件，它可以是直接连接另一个元件或者可能同时存在居中元件。
请参阅图1-8，本发明的实施例提供了一种应用于潜望式镜头模组的棱镜装置1，所述应用于潜望式镜头模组的棱镜装置1包括承载架10、复位装置20、支撑件30、若干形状记忆合金线40以及安装于支撑件30上以用于接收光线的棱镜50，支撑件30通过复位装置20可运动地安装于承载架10上，若干形状记忆合金线40连接于承载架10与支撑件30之间用以驱动支撑件30在承载架10内可绕X轴方向转动或者绕Y轴方向转动，使得棱镜50在若干形状记忆合金线40的驱动作用下能自动校正角度，应用该应用于潜望式镜头模组的棱镜装置1的潜望式镜头模组的成像角度更广，其成像效果更好，形状记忆合金线40可由程序发出指令以使其形成记忆效应产生驱动力。本发明中定义沿承载架10的宽度方向为X轴方向，沿承载架10的高度方向为Y轴方向，沿承载架10的长度方向为Z轴方向，X轴方向、Y轴方向和Z轴方向两两相互垂直。
请参阅图2和图3，具体地，承载架10包括侧板11、底板12以及两个第一限位板13，底板12的一端与侧板11的一端垂直连接，两第一限位板13分别与侧板11的另一端和底板12的另一端垂直连接，侧板11之朝向支撑件30的一侧面上设若干卡扣14，所述卡扣14可直接一体成型于侧板11上，也可以通过任意一种现有的装配方式装配于侧板11上，本实施例中的卡扣14安装于侧板11上，这样可以简化承载架10的结构、降低承载架10的制作成本。支撑件30通过若干形状记忆合金线40安装于卡扣14上，两个第一限位板13用于限制支撑件30移出承载架10，底板12上对应复位装置20的表面设有卡槽121，用于对复位装置20进行粗定位，以提高复位装置20与承载架10之间的装配效率和准确度。
请参阅图1、图2和图4，支撑件30包括用于支撑棱镜50的支撑架31以及与承载架10间隔设置的支撑板32，本实施例中支撑板32与承载架10的侧板11平行设置且在支撑板32上设有供支撑架31卡插装配用的安装槽321，支撑架31包括与支撑板32连接的连接部311、用于安装棱镜50的斜板312以及与斜板312两端分别连接且均与斜板312呈夹角设置的第二限位板313，连接部311的一端与斜板312中部连接，连接部311的另一端穿过复位装置20后与支撑板32上的安装槽321卡插连接，连接部311与复位装置20的连接处形成抵接部314，作为优选的实施方式，抵接部314的厚度大于连接部311其他部位的厚度以增加其强度，具体地，抵接部314的顶面和底面高出连接部311其他部位的顶面和底面。两第二限位板313分别与两第一限位板13相对应，以防止应用于潜望式镜头模组的棱镜装置1发生跌落时，支撑架31从承载架10内甩出。
请参阅图5，作为优选的实施方式，支撑板32之朝向侧板11的一侧凸设有若干个分别与各卡扣14相配合且用于固定各形状记忆合金线40的挂钩322，本实施例中形状记忆合金线40、卡扣14和挂钩322的数量都为四个，各形状记忆合金线40的两端分别与相邻两卡扣14固定连接，各形状记忆合金线40的中部与各挂钩322滑动连接，这样，每一条形状记忆合金线40呈V型形状，四个挂钩322分别设置于四边形的四个边，每一挂钩322的横截面呈“L”形，可避免形状记忆合金线40因为晃动而掉出。
请参阅图2和图6，本实施例中，复位装置20包括第一弹性架21及第二弹性架22，优选地，第一弹性架21和第二弹性架22都由单个弹性材料弯折而成，第一弹性架21和第二弹性架22围合形成用于固定支撑架31的连接部311的夹持结构23。
作为优选的实施方式，第一弹性架21包括第一夹持部211、从第一夹持部211两端弯折延伸的两第一延伸部212、连接至第一延伸部212末端的第一弯折部213、从第一弯折部213末端延伸的第二延伸部214以及从第二延伸部214末端弯折而成的第一安装部215。优选地，第一弯折部213为U形结构，U形结构的两端分别连接至第一延伸部212和第二延伸部214，第一延伸部212和第二延伸部214平行设置，第一安装部215与底板12平行并卡设于卡槽121内。
第二弹性架22具有类似结构，包括第二夹持部221、从第二夹持部221两端弯折延伸的两第三延伸部222、连接至第三延伸部222末端的第二弯折部223、从第二弯折部223末端延伸的第四延伸部224以及从第四延伸部224末端弯折而成的第二安装部225。优选地，第二弯折部223为U形结构，U形结构的两端分别连接至第三延伸部222和第四延伸部224，第三延伸部222和第四延伸部224异面设置，第三延伸部222和第四延伸部224与第二弯折部223所在的平面垂直，第二安装部225与底板12平行并卡设于卡槽121内。第一弹性架21的第一夹持部211和第二弹性架22的第二夹持部221分别夹持于连接部311的抵接部314的两侧，共同构成夹持结构23，第一夹持部211和第二夹持部221的延伸方向与抵接部314的延伸方向一致。第一夹持部211和第二夹持部221上均设有分别用于与抵接部314的顶面和底面相抵靠的抵靠部216，抵靠部216的宽度大于第一夹持部211和第二夹持部223其他部位的宽度，与抵接部314的宽度一致，该抵靠部216的设置可以提高支撑架31与复位装置20之间的装配精度及强度。
请参阅图2、图5和图7，四条形状记忆合金线40在应用于潜望式镜头模组的棱镜装置1内等均分设置于支撑板32与侧板11之间，优选地，四个卡扣14分别位于一四边形的四个角，四个挂钩322位于另一四边形的四条边，所述另一四边形靠近该一四边形的中心位置。这样，四条形状记忆合金线40可用于通过支撑件间接驱动棱镜50相对于承载架10实现Y轴方向的推力，带动棱镜50绕X轴转动，四条形状记忆合金线40驱动棱镜50相对于承载架10实现X轴方向的推力，带动棱镜50绕Y轴转动。
具体地，四条形状记忆合金线40可分别定义为第一形状记忆合金线41、第二形状记忆合金线42、第三形状记忆合金线43和第四形状记忆合金线44，其中，第一形状记忆合金线41和第三形状记忆合金线43沿Y轴方向分别设置于侧板11的上下两侧，且第一形状记忆合金线41位于第三形状记忆合金线43上方，第二形状记忆合金线42和第四形状记忆合金线44沿X轴方向分别设置于侧板11的左右两侧，如图7所示的方位，第二形状记忆合金线42位于右侧，第四形状记忆合金线44位于左侧。
具体操作时，如图1所示，当第一形状记忆合金线41通电发热缩短时，支撑件30的支撑板32受到斜向上的拉力并将此力传递至支撑架31的连接部311，从而使得支撑架31绕连接部311的被夹持于复位装置20的夹持结构23内的抵接部314为支点绕X轴沿逆时针方向转动，从而带动棱镜50相对于承载架10实现绕X轴的逆时针方向转动；当第三形状记忆合金线43通电发热缩短时，棱镜50相对于承载架10实现绕X轴作顺时针方向转动；当第二形状记忆合金线42通电发热缩短时，棱镜50可相对于承载架10实现绕Y轴沿一个方向转动；当第四形状记忆合金线44通电发热缩短时时，棱镜50可相对于承载架10实现绕Y轴沿另一相反方向转动。本申请的形状记忆合金线40也可以称之为SMA线，在此不作详细描述。
请参阅图9，本发明还提供一种潜望式镜头模组，该潜望式镜头模组包括框架60、透镜组件70、棱镜系统80以及应用于潜望式镜头模组的棱镜装置1，透镜组件70安装于框架60的中部，棱镜系统80安装于框架60的一端并位于透镜组件70的像侧，应用于潜望式镜头模组的棱镜装置1安装于框架60的另一端并位于透镜组件70的物侧以用于接收光线，光线经应用于潜望式镜头模组的棱镜装置1反射后沿着透镜组件70的轴线方向直线到达棱镜系统80以进行成像，由Y轴方向入射的光线经应用于潜望式镜头模组的棱镜装置1反射后沿Z轴进入到透镜组件70内，沿Z轴进入到透镜组件70内的光线再经棱镜系统80反射后沿X轴方向射出，潜望式镜头模组可应用于具有摄像功能的电子设备中，优选地，该具有摄像功能的电子设备为手机或者相机。
以上所述的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
