本申请涉及摄像技术领域，特别涉及一种变焦结构及摄像装置。
背景技术

具体实施方式
下面将结合本申请实施方式中的附图，对本申请实施方式中的技术方案进行清楚、完整地描述，显然，所描述的实施方式仅仅是本申请一部分实施方式，而不是全部的实施方式。基于本申请中的实施方式，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施方式，都属于本申请保护的范围。
请结合参阅图1及图2，图1是本申请第一实施方式提供的摄像装置的剖面示意图；图2是图1所示的摄像装置的变焦结构的部分结构的立体示意图。
本申请提供一种摄像装置200，其包括图像传感器201、电路板(图未示)及变焦结构100，图像传感器201与电路板电性连接，变焦结构100用于摄取来自被摄物的光，图像传感器201用于接收通过变焦结构100的光，并将所接收到的光转为电信号。
本申请提供的摄像装置200可以包括但不限于变焦结构100的手机(如Android手机、iOS手机等)、平板电脑、移动互联网设备(Mobile Internet Devices，MID)、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑等等，本 申请对此不作限定。
上述变焦结构100，包括第一透镜结构10、第二透镜结构30、移动导板50及第一驱动装置70，第一透镜结构10及第二透镜结构30沿第一方向排列设置，移动导板50包括板体51及间隔设置于板体51上的第一导向部53及第二导向部54，第一导向部53的至少部分及第二导向部54的至少部分均相对第一方向倾斜设置，第一透镜结构10与第一导向部53滑动连接，第二透镜结构30与第二导向部54滑动连接，第一驱动装置70用于驱动第一透镜结构10沿第一方向移动，进而带动移动导板50沿第二方向移动，及第二透镜结构30沿第二导向部54在第一方向上移动，所述第一方向不同于第二方向。
本申请提供的变焦结构100及摄像装置200，在第一驱动装置70驱动第一透镜结构10沿第一方向移动时，能够带动移动导板50沿第二方向移动，以及带动第二透镜结构30沿第二导向部54在第一方向上移动。例如，在本实施方式中，如图3所示，第一滑块13沿第一导向部53于第一方向从A点移动至B点，带动移动导板50沿第二方向从I位置移动至Ⅱ位置(如图3的点划线所示区域)，进而带动第二滑块33沿第二导向部54于第一方向从C点移动至D点。其中，第一驱动装置70驱动第一透镜结构10沿第一方向移动的过程为变焦过程，移动导板50沿第二方向移动进而带动第二透镜结构30沿第一方向移动的过程为第一对焦过程。如此，随着第一透镜结构10移动(即变焦过程)的同时，第二透镜结构30也能够相应移动以调整位置(即第一对焦过程)，使得通过第一透镜结构10的被摄物光线在图像传感器201上能够成像清晰，节省第二透镜结构30的行程需求，即不需要再单独使第二透镜结构30进行大行程的移动，可以减少第二透镜结构30移动行程中的动态倾斜(Tilt)，减少驱动时的动力损耗，节省驱动时所耗费的时间。
本实施方式中，第二方向垂直于第一方向。可以理解，不限制第二方向垂直于第一方向，例如，第二方向与第一方向之间的夹角还可以为锐角或钝角。
第一透镜结构10沿第一方向移动时，能够带动移动导板50沿第二方向移动，可以理解为，第一透镜结构10相对移动导板50移动，第一透镜结构10相对移动导板50的移动路径与第一导向部53的至少部分延伸路径相同。同样的，在移动导板50沿第二方向移动带动第二透镜结构30沿第一方向移动时， 可以理解为第二透镜结构30相对移动导板50移动，第二透镜结构30相对移动导板50的移动路径与第二导向部54的至少部分延伸路径相同。
请参阅图4，在第一透镜结构10相对移动导板50移动的过程中，第一透镜结构10于第一导向部53中的位置与第二透镜结构30于第二导向部54中的位置始终一一对应。例如，在第一透镜结构10相对移动导板50从G1位置移动到N1位置的过程中，第二透镜结构30也相对移动导板50从G2位置移动到N2位置。当第一透镜结构10位于第一导向部53中的G1位置时，第二透镜结构30位于第二导向部54的G2位置，G1位置与G2位置的连线平行于第一方向。当第一透镜结构10位于第一导向部53的N1位置时，第二透镜结构30位于第二导向部54的N2位置，N1位置与N2位置的连线平行于第一方向。其中，第一透镜结构10于第一方向的移动距离，为G1位置与N1位置之间的连线于第一方向的长度。第二透镜结构30从G2位置移动到N2位置的过程中，第二透镜结构30于第一方向的移动距离，为G2位置与N2位置之间的连线于第一方向的长度，在本实施方式中，G1位置与N1位置之间的连线于第一方向的长度小于G2位置与N2位置之间的连线于第一方向的长度。
在本实施方式中，第一导向部53沿直线延伸，第二导向部54沿直线延伸。第一导向部53包括第一端531及第二端533，第一端531及第二端533分别位于第一导向部53的延伸路径的两端，第二端533位于第一端531靠近第二方向的正方向的一侧。第二导向部54包括第三端541及第四端543，第三端541及第四端543分别位于第二导向部54的延伸路径的两端，第四端543位于第三端541靠近第二方向的正方向的一侧。在本实施方式中，第一导向部53的第二端533设置于第一端531朝向第一方向的正方向的一侧，并且，第二导向部54的第四端543设置于第三端541朝向第一方向的正方向的一侧。第一导向部53的延伸路径长度小于第二导向部54的延伸路径长度，第一导向部53沿第一方向的长度(即第一端531与第二端533于第一方向上的距离)小于第二导向部54沿第一方向的长度(即第三端541与第四端543于第一方向上的距离)。如此，第一透镜结构10沿第一方向朝靠近图像传感器201一侧(即第一方向的负方向)移动时，第二透镜结构30也沿第一方向朝靠近图像传感器201一侧(即第一方向的负方向)移动；或者，当第一透镜结构10沿 第一方向朝第一方向的正方向移动时，第二透镜结构30也沿第一方向朝第一方向的正方向移动；并且第二透镜结构30沿第一方向移动的距离大于第一透镜结构10沿第一方向移动的距离。
第一导向部53的延伸路径及第二导向部54的延伸路径需要对应第一透镜结构10与第二透镜结构30于变焦过程及第一对焦过程中的位置关系设置，即第一导向部53的延伸路径需要满足第一透镜结构10相对移动导板50移动的路径，第二导向部54的延伸路径需要满足第二透镜结构30相对移动导板50移动的路径，使得第一滑块13沿第一方向移动一定距离时，第二滑块33亦沿第一方向移动对应距离即可。
可以理解，不限制第一导向部53沿直线延伸，第二导向部54沿直线延伸，例如，在变更实施方式中，第一导向部53沿直线延伸，第二导向部54沿曲线延伸。在变更实施方式中，第一导向部53沿曲线延伸，第二导向部54沿曲线延伸。在变更实施方式中，第一导向部53沿曲线延伸，第二导向部54沿直线延伸。
可以理解，不限制第一导向部53的延伸路径的长度小于第二导向部54的延伸路径的长度，不限制第一导向部53沿第一方向的长度(即第一端531与第二端533于第一方向上的距离)小于第二导向部54沿第一方向的长度(即第三端541与第四端543于第一方向上的距离)。例如，在变更实施方式中，第一导向部53的延伸路径长度可以大于第二导向部54的延伸路径长度。在变更实施方式中，第一导向部53沿第一方向的长度(即第一端531与第二端533于第一方向上的距离)可以大于第二导向部54沿第一方向的长度(即第三端541与第四端543于第一方向上的距离)。
可以理解，不限制第一导向部53的第二端533设置于第一端531朝向第一方向的正方向的一侧，并且，第二导向部54的第四端543设置于第三端541朝向第一方向的正方向的一侧。在变更实施方式中，第一导向部53的第二端533可以但不限于设置于第一端531朝向第一方向的负方向的一侧，并且，第二导向部54的第四端543设置于第三端541朝向第一方向的负方向的一侧。如此，第一透镜结构10沿第一方向的负方向移动时，第二透镜结构30亦沿第一方向的负方向移动；当第一透镜结构10沿第一方向的正方向移动时，第二 透镜结构30亦沿第一方向的正方向移动。
可以理解，不限制第一透镜结构10沿第一方向的负方向移动时，第二透镜结构30亦沿第一方向的负方向移动。在变更实施方式中，当第一透镜结构10沿第一方向的负方向移动时，第二透镜结构30可以沿第一方向的正方向移动；当第一透镜结构10沿第一方向的正方向移动时，第二透镜结构30可以沿第一方向的负方向移动。相应的，将第一导向部53的第二端533设置于第一端531朝向第一方向的负方向的一侧，并将第二导向部54的第四端543设置于第三端541朝向第一方向的正方向的一侧；或者，将第一导向部53的第二端533设置于第一端531朝向第一方向的正方向的一侧，并将第二导向部54的第四端543设置于第三端541朝向第一方向的负方向的一侧。
如图1及图2所示，第一透镜结构10包括固定连接的第一透镜组11、第一滑块13及第一透镜支架15。第一滑块13与第一导向部53滑动连接。具体地，第一导向部53为设置于板体51上的第一狭槽，第一滑块13活动容置于第一狭槽。
第一透镜支架15上开设沿第一方向延伸的第一凹槽151及沿第一方向延伸的第二凹槽153，第二凹槽153设置于第一透镜支架15背离第一凹槽151的一侧，第一透镜组11固定容置于第一凹槽151。第二透镜结构30活动容置于第二凹槽153。如此，第二凹槽153为第二透镜结构30的运动提供导向，便于第一透镜结构10与第二透镜结构30始终同光轴设置，第一透镜结构10沿第一方向移动时，第二透镜结构30亦能在第二凹槽153中移动相应的距离。
可以理解，不限制第一透镜支架15包括第二凹槽153，第二透镜结构30活动容置于第二凹槽153，即第二凹槽153也可以省略，第二透镜结构30满足与第一透镜支架15滑动连接即可。
在本实施方式中，第二透镜结构30包括第二透镜组31、第二滑块33、第二透镜壳体35、弹性元件(图未示)及第二驱动装置(图未示)。第二滑块33与第二透镜壳体35固定连接，第二滑块33与第二导向部54滑动连接，第二透镜壳体35活动容置于第二凹槽153。第二导向部54为设置于板体51上的第二狭槽，第二滑块33活动容置于第二狭槽。第二透镜组31通过弹性元件(图未示)与第二透镜壳体35沿第一方向滑动连接。弹性元件用于为第二透镜组 31提供支撑，并且为第二透镜组31相对第二透镜壳体35的移动预留空间。第二透镜组31用于使被摄体的光线在图像传感器201上清晰成像。第二透镜壳体35用于在变焦过程的同时带动第二透镜组31移动，从而完成第一对焦过程。具体地，在第一透镜结构10沿第一方向的移动(变焦过程)时，第二透镜组31能够随着第二透镜壳体35沿第一方向移动(第一对焦过程)。第二驱动装置用于驱动第二透镜组31相对第二透镜壳体35沿第一方向移动，即在第一对焦过程完成后，第二驱动装置能够驱动第二透镜组31相对第二透镜壳体35沿第一方向移动，进一步调整第二透镜组31与第一透镜结构10之间的距离，也即调整第二透镜组31到图像传感器201的距离，完成第二对焦过程，进一步提升成像的清晰度。相较于现有技术，本申请在进行第二对焦过程之前，使第二透镜结构30随着第一透镜结构10移动一定距离，减少了设置于第二透镜结构30内部的第二透镜组31的行程需求，后续第二透镜组31只需要在第二透镜结构30内部做小范围的调整，进行小行程的对焦与寻焦动作，即能够实现较高的清晰度，如此，减少驱动时的动力损耗，节省驱动时所耗费时间。
在本实施方式中，第一透镜组11与第二透镜组31同光轴(如图1所示L)设置。可以理解，不限制第一透镜组11与第二透镜组31同光轴设置，满足通过第一透镜组11的光线能够经第二透镜组31照射到图像传感器201上即可。
在本实施方式中，弹性元件可以但不限于为弹簧片等。
可以理解，不限制第一导向部53为设置于板体51上的第一狭槽，第一滑块13活动容置于第一狭槽中，满足第一滑块13能够沿第一导向部53滑动的情形均在本申请的保护范围之内，例如，在变更实施方式中，第一导向部53可以但不限于为导杆，第一滑块13活动套设于导杆，使第一滑块13能够第一导向部53移动。同样地，不限制第二导向部54为设置于板体51上的第二狭槽，第二滑块33活动容置于第二狭槽，满足第二滑块33能够沿第二导向部54滑动的情形均在本申请的保护范围之内，例如，在变更实施方式中，第二导向部54可以但不限于为导杆，第二滑块33活动套设于导杆，使第二滑块33能够沿第二导向部54移动。
第一驱动装置70为压电驱动装置，即利用压电陶瓷材料的逆压电效应，当输入一定的电压时，压电驱动装置将产生随电压升高而逐渐增大的变形量， 从而将电能转变成机械运动，具有强度大，功耗低，响应速度快，位移控制精度高等一系列优点。可以理解，不限制第一驱动装置70为压电驱动装置，第一驱动装置70还可以但不限于为步进电动机、直流伺服电动机或交流伺服电动机等，即第一驱动装置70能够驱动第一透镜结构10沿第一方向移动即可。可以理解，不限制第二驱动装置的类型，第二驱动装置可以但不限于为步进电动机、直流伺服电动机或交流伺服电动机等，即第二驱动装置能够驱动第二透镜组31相对第二透镜壳体35沿第一方向移动即可。
