Description

透镜驱动装置、摄像装置以及移动终端 技术领域
本发明涉及摄像装置领域，具体而言，涉及一种透镜驱动装置、摄像装置以及移动终端。
背景技术
摄像机或者照相机，通常会采用焦距可调或者自动对焦的镜头，而调节的过程则是改变镜头的位置，用于驱动镜头移动通常是用驱动马达。目前，手持式摄像装置—尤其是手机的摄像头的自动调焦基本全部使用音圈电机(Voice Coil Motor，VCM)来完成，音圈马达是一个由线圈和磁石组成的系统。通电后的线圈在磁场中会受到电磁力，由于电磁力的作用驱使绕线载体沿镜头光轴方向(即Z轴)作直线移动，绕线载体最终停留于环状线圈与驱动磁石之间产生的电磁力与上弹簧及下弹簧的弹性力的合力达到相均衡状态时的位置点。
虽然音圈电机具有技术成熟、成本低、噪音低等优点，但是随着摄像装置对摄像要求的增加，音圈电机在存在磁干扰、推力不足、结构及性能不稳定的问题。例如：双摄马达被开发应用于各种中高端手机中，但实际运用过程中存在一定的困扰难点，特别是两颗双摄马达彼此间存在一定程度的磁干扰现象，影响双摄马达效果的正常发挥，音圈马达无法避免该缺陷，同时，各种改进方案都容易造成马达结构复杂，组装工艺难度的提升；音圈马达中各个部品之间的电气性导通和连接组装均通过焊接、热铆、点胶等方式实现，同时线圈通电需要通过上/下弹簧连通，导致线圈通电的通路较长，由于音圈马达部品数较多，需要焊接、热铆、点胶处较多，当手机一旦在受到跌落撞击等外力时，马达由于外力震荡容易导致内部焊接点或点胶处拉扯脱落或弹簧变形等现象，最终马达内部的电气性能和组合结构受到破坏，影响马达正常性能的发挥，给拍摄效果带来不利后果。
目前镜头的OIS防抖基本常用的有两种技术，一种是SHIFT(平移式)方式，另一种是TITLE(移轴式)方式。其中，平移式通过直接平移镜头来补偿运动，而移轴式则是选择倾斜镜头来补偿。SHIFT方式的工作原理是在整个平台上有二组音圈马达，就是X、Y轴控制抖动，Z轴控制的是AF。二组马达的驱动方式都是线圈驱动式。Z轴的工作原理和正常的AF工作原理是一致的。TITLE方式的光学防抖功能工作原理是在一个运动载体上有四组线圈，通过四组线圈的分别通电，进行控制AF过程中的光轴变化。从运用来说，SHIFT和TITLE在防抖功能方面来说，都可以达到光学防抖的效果，目前市场上的手机基本运用了都是该两种方式中的其中一种。 同时，主要采用悬丝等支撑的平移型防抖结构，利用电流改变悬丝的长度，带动镜头沿X-Y轴反向移动，减少光轴中心与被摄物之间移动的幅度。而现有的移轴型防抖结构，普遍结构复杂，不利于组装工艺。
因此，现有技术中存在摄像装置的驱动装置使用性能差的问题。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
需要指出的是，除非另有指明，本申请使用的所有技术和科学术语具有与本申请所属技术领域的普通技术人员通常理解的相同含义。

为了解决现有技术中摄像装置的驱动装置使用性能差的问题，本申请提供了一种透镜驱动装置、摄像装置以及移动终端。
需要指出的是，本申请中的移动终端具有摄像装置，并且，本申请中的摄像装置具有下述的透镜驱动装置。
如图1至图11所示，本申请中的透镜驱动装置包括外壳10和底座组件20，外壳10罩设在底座组件20上并与底座组件20之间形成容置空间，透镜驱动装置还包括设置在容置空间内的镜头座30和第一弹性支撑组件40。镜头座30活动设置在容置空间的内部；第一弹性支撑组件40为多个，多个第一弹性支撑组件40支撑在镜头座30与底座组件20之间或者支撑在镜头座30与外壳10之间，多个第一弹性支撑组件40绕镜头座30的周缘设置，且多个第一弹性支撑组件40中的至少一个第一弹性支撑组件40通电以使第一弹性支撑组件40的至少一部分产生形变并带动镜头座30沿Z轴方向运动或者带动镜头座30相对Z轴偏斜。
使用本申请中的透镜驱动装置时，由于镜头驱动装置具有镜头座30，所以能够使移动终端的镜头安装在镜头座30上，并且由于还具有多个第一弹性支撑组件40，所以能够通过第一弹性支撑组件40的形变带动镜头座30移动，从而带动镜头座30沿Z轴方向运动或者相对Z轴方向产生偏斜，进而实现自动调焦功能或者防抖功能。 当多个第一弹性支撑组件40的变形量相同时，多个第一弹性支撑组件40能够带动镜头座30沿Z轴方向运动并实现AF驱动。而当多个第一弹性支撑组件40的变形量不同时，能够实现移轴防抖功能。也就是说，在本申请中，通过透镜驱动装置的第一弹性支撑组件40代替了原有的音圈马达中的驱动线圈、驱动磁石部分以及悬丝防抖部分。并且，由于本申请中不再需要与驱动磁石和驱动线圈相配合的弹簧等结构，所以本申请中的透镜驱动装置相对现有的音圈马达的结构更加简单。同时还不存在磁铁，所以不会产生对内或对外的磁干扰问题。并且，本申请中的透镜驱动装置没有磁路设计问题，整个行程力度平均推力较电磁方式大，因此与现有的音圈马达相比更有效率。并且，没有音圈马达的上、下弹簧设计，跌落和滚筒等测试不会有弹簧变形、镍或异物脱落问题。又由于本申请中的第一弹性支撑组件40本身就具有阻尼作用，因此本申请中的透镜驱动装置不再需要外加阻尼胶。在本申请中，由于仅通过第一弹性支撑组件40对镜头座30进行驱动，所以与音圈马达的电磁驱动方式相比，需要的组件更少，所以能够有利于镜头驱动装置的小型化。因此，本申请中的透镜驱动装置有效地解决了现有技术中摄像装置的驱动装置使用性能差的问题。
需要指出的是，在本申请中，当多个第一弹性支撑组件40的变形量不同并且能够带动镜头座30相对Z轴产生偏斜时，此时的防抖形式为移轴式防抖。
在本申请的下述实施例中，第一弹性支撑组件40是设置在镜头座30与底座之间的。
需要说明的是，在本申请中，外壳10上与底座相对的一面具有开口结构，并且，开口结构能够对移动终端的镜头进行避让。
具体地，镜头座30的每个角部处分别对应至少一个第一弹性支撑组件40。通过这样设置可以有效地保证当多个第一弹性支撑组件40的变形量相同并带动镜头座30沿Z轴方向运动时，可以有效地保证镜头座30受力的稳定性，以及防止此时的镜头座30不会产生偏斜。
并且，在本申请的一个具体实施例中，第一弹性支撑体41组件为4个，并且镜头座30的每个角部处分别具有一个第一弹性支撑体41组件。
具体地，第一弹性支撑组件40包括第一弹性支撑体41和第一挤压结构42。第一挤压结构42通电以向第一弹性支撑体41提供挤压力，当第一弹性支撑体41受第一挤压结构42挤压时，第一弹性支撑体41产生形变并带动镜头座30运动。也就是说，在本申请中的透镜驱动装置中，当需要对镜头进行调焦或者防抖时，第一挤压 结构42会通电并对第一弹性支撑体41产生挤压，从而通过多个第一弹性支撑体41的形变带动镜头座30运动，进而使得镜头座30能够带动镜头沿Z轴方向运动或者相对Z轴方向偏斜。当然，在本申请中也可以将第一挤压结构42设置成其他形式，只要能够控制第一挤压结构42可以对第一弹性支撑体41进行挤压即可。
在本申请的一个具体实施例中，镜头座30包括第一筒状结构31和第一抵接凸缘32。第一筒状结构31的内部用于容置镜头50；第一抵接凸缘32设置在第一筒状结构31远离底座组件20的一端，且第一弹性支撑体41支撑在第一抵接凸缘32和底座组件20之间。在本实施例中，设置第一筒状结构31能够容置移动终端的镜头。而通过设置第一抵接凸缘32则可以保证第一弹性支撑体41的一端能够与第一抵接凸缘32抵接，这样能够保证第一弹性支撑体41在受力产生形变后，第一弹性支撑体41能够带动镜头座30一同运动，而不会出现第一弹性支撑体41相对镜头座30运动的情况，以保证透镜驱动装置的性能稳定。
优选地，第一抵接凸缘32和底座组件20对应第一弹性支撑体41分别设置有定位槽60，第一弹性支撑体41的两端分别伸入对应的定位槽60并分别与第一抵接凸缘32和底座组件20抵接。在本申请中，当多个第一弹性支撑体41的变形量不同时，镜头座30会相对Z轴方向产生偏斜，所以通过设置定位槽60能够保证在镜头座30相对Z轴方向产生偏斜时，第一弹性支撑体41与镜头座30接触的部分不会相对镜头座30滑动，而是始终保持在定位槽60的内部。
优选地，第一弹性支撑体41的两端对应定位槽60分别设置有定位凸缘411，定位凸缘411的至少一部分伸入定位槽60的内部。
优选地，第一抵接凸缘32的定位槽60和底座组件20的定位槽60的内部分别设置有定位柱61，第一弹性支撑体41的两端分别对应定位柱61设置有定位孔412。通过这样设置可以进一步有效地保证第一弹性支撑体41与镜头座30之间接触的稳定性。
在本申请的一个具体实施例中，第一挤压结构42包括第一SMA丝线421和第一端脚组件422。第一SMA丝线421绕设在第一弹性支撑体41的周向外侧壁上；第一端脚组件422设置在底座组件20上，且第一SMA丝线421与第一端脚组件422电连接。并且，第一SMA丝线421的两端分别由第一弹性支撑体41沿Z轴方向的两端伸出，透镜驱动装置还包括连接臂70、连接环71、第一FPC板72。连接臂70为多个，多个连接臂70与多个第一弹性支撑组件40一一对应，且第一SMA丝线421靠近底座组件20的一端通过对应的连接臂70与第一端脚组件422电连接；连 接环71分别与不同的第一SMA丝线421远离底座组件20的一端电连接；第一FPC板72设置在底座组件20上，且第一FPC板72分别与连接环71以及不同的第一端脚组件422电连接。
优选地，多个第一弹性支撑组件40的第一弹性支撑体41绕连接环71的周向间隔设置，且连接环71的外周缘具有多个连接凸起，连接凸起与SMA丝线或者第一FPC板72电连接。
具体地，第一FPC板72与连接环71连接的一端和第一FPC板72朝向底座组件20延伸的一端具有沿Z轴弯折成型的缓冲段721，且缓冲段721为弓形段。通过这样设置，当镜头座30沿Z轴方向运动或沿Z轴移轴运动时，第一FPC板72的缓冲段721能够进行延伸或者收缩，从而保证第一SMA丝线421和第一端脚组件422之间电连接的稳定性。
可选地，底座组件20包括本体部21，第一弹性支撑体41支撑在第一抵接凸缘32和本体部21之间。并且，底座组件20还包括支撑架22，支撑架22设置在本体部21和镜头座30之间，且第一弹性支撑体41的两端分别与第一抵接凸缘32和支撑架22抵接。
在本申请的一个具体实施例中，透镜驱动装置还包括第二弹性支撑组件80，第二弹性支撑组件80支撑在本体部21和支撑架22之间，且第二弹性支撑组件80通电以使第二弹性支撑组件80的至少一部分产生形变并带动支撑架22沿Z轴方向运动。并且，第二弹性支撑组件80包括：第二弹性支撑体81，本体部21朝向支撑架22的一侧具有支撑凸环211，第二弹性支撑体81靠近本体部21的一端套设在支撑凸环211上；第二挤压结构82，第二挤压结构82通电以向第二弹性支撑体81提供挤压力，当第二弹性支撑体81受第二挤压结构82挤压时，第二弹性支撑体81产生形变并带动支撑架22运动。
在本申请的一个具体实施例中，第二挤压结构82包括第二SMA丝线821和第二端脚组件822。第二SMA丝线821绕设在第二弹性支撑体81的周向外侧壁上；第二端脚组件822设置在本体部21上，且第二SMA丝线821的两端分别与第二端脚组件822连接。在本实施例中第二SMA丝线821的输入、输出端与第二端脚组件822进行电连接，并且第二SMA丝线821与第二端脚组件822之间的连接方式可以是焊接或者是通过夹头、卡扣等方式进行连接，只要保证第二SMA丝线821的输入、输出端与端脚组件之间的连接稳定性即可。
并且，在本申请中透镜驱动装置还可以包括第二FPC板，并且第二FPC板用 于连接第二SMA丝线和第二端脚组件。
需要指出的是，在本申请中通过设置第一弹性支撑体41和第二弹性支撑体81还可以使摄像装置跌落过程中受到的冲力小，并能起到一定的缓冲防振作用，同时，跌落和滚筒等测试不会有镍或异物脱落问题，能保护马达内部结构，也无需再额外设置阻尼胶，既简化组装工艺又能提高结构稳定性。
并且，需要说明的是，在本申请中第二弹性支撑体81的直径是大于第一弹性支撑体41的。
可选地，支撑架22包括第二筒状结构221和第二抵接凸缘222。第二筒状结构221朝向第二弹性支撑体81延伸并伸入第二弹性支撑体81的内部；第二弹性支撑体81远离本体部21的一端与第二抵接凸缘222抵接。
具体地，本体部21朝向镜头座30的一侧还具有至少一个导向柱212，第一抵接凸缘32具有与导向柱212间隙配合的导向孔321。需要说明的是，在镜头座30运动的过程中，镜头座30与导向柱212之间始终是不接触的，以使镜头座30能顺利向Z轴方向运动。在本申请中，设置导向柱212的目的是通过导向孔321与导向柱212的间隙配合，使得镜头座30能够套设于导向柱212中，在镜头座30的运动过程中，通过导向柱212为镜头座30的运动提供导向和抗扭作用。
当然，在本申请中，根据实际的使用情况也可以将镜头座30设置成是与导向柱212能够接触的。
具体地，导向柱212朝向导向孔321的一端具有收缩段，收缩段伸入导向孔321，且收缩段与导向孔321的周向内侧壁之间具有活动间隙。通过这样设置，当多个第一弹性支撑体41的变形量不同时，镜头座30会相对Z轴方向出现偏斜，此时镜头座30同时也会相对导向柱212出现偏斜，因此通过在收缩段和导向孔321之间设置活动间隙，可以为镜头座30的运动提供避让空间。
优选地，支撑架22具有用于避让导向柱212的让位孔223，导向柱212穿过让位孔223并伸入导向孔321，且导向柱212与让位孔223之间间隙配合。当然，在本申请中，当导向柱212穿过让位孔223后，也可以不进入导向孔321。
优选地，第一弹性支撑体41和第二弹性支撑体81呈环状。通过这样设置，不仅能够方便支撑架22与第二弹性支撑体81的连接，可以还可以保证第二弹性支撑体81在受到第二挤压结构82的挤压力而产生形变后，支撑架22能够更加均匀的受力，从而保证镜头座30的运动不会产生偏斜，以保证移动终端的对焦效果和拍摄效果。从另一方面来说，也可以将第二弹性支撑体81看成是环状的，并且通过这样设 置可以使得第二弹性支撑体81能够起到防尘的作用，从而提高透镜驱动装置的密封性能。
并且第一弹性支撑体41和第二弹性支撑体81中间部分的直径大于两端的直径。也就是说，沿Z轴方向第一弹性支撑体41和第二弹性支撑体81的中间部分的直径分别大于两端的直径。在本申请中，这样设置的目的是第一弹性支撑体41和第二弹性支撑体81主要是通过中间部分的形变来产生沿Z轴方向的延伸，从而能够带动镜头座30实现大行程驱动。并且，通过这样设置，在第一弹性支撑体41和第二弹性支撑体81受力产生形变后，第一弹性支撑体41和第二弹性支撑体81中间部分的直径不会过小，从而保证第一弹性支撑体41和第二弹性支撑体81在受到挤压力后不会出现偏斜，进而保证第一弹性支撑体41和第二弹性支撑体81的稳定性，并保证透镜支撑体的调焦稳定性，保证移动终端的拍摄效果，防止拍摄出的图像模糊。
当然，需要指出的是，在本申请中第一弹性支撑体41和第二弹性支撑体81的形状并不限制于环状或者圆筒状，而且还可以根据实际的设计需求将第一弹性支撑体41和第二弹性支撑体81设置成其他形状，例如正多边形的筒状结构。
可选地，第一弹性支撑体41和第二弹性支撑体81的内部具有填充空间，填充空间的内部填充有液体或者气体。通过这样设置，能够在保证第一弹性支撑体41和第二弹性支撑体81的形变性能外，还能够通过填充的液体或者气体来保证第一弹性支撑体41和第二弹性支撑体81的支撑效果，并使第一弹性支撑体41和第二弹性支撑体81在不受挤压力时能够具有一定的形状。
在本申请的一个具体实施例中，透镜驱动装置还包括防抖结构，防抖结构设置在底座组件20远离镜头座30的一端，防抖结构与底座组件20驱动连接，以使防抖结构能够带动底座组件20沿X轴和/或Y轴方向运动。需要说明的是，在本申请中，通过设置防抖结构能够使透镜驱动装置在具有轴移式防抖功能的同时，还能够具有平移式的防抖功能。并且，在本实施例中防抖结构包括丝线、簧片、基板组件、压片组件以及滚珠组件。丝线与簧片固定连接；压片组件的至少一部分设置在基板组件朝向簧片的一侧，压片组件与丝线电连接，以使丝线在电流的作用下收缩或者膨胀并带动簧片的至少一部分沿预定方向移动；滚珠组件设置在簧片朝向基板组件的一侧，滚珠组件的至少一部分与簧片连接，且滚珠组件的至少另一部分与基板组件滚动接触，以使滚珠组件相对基板组件滑动。使用本实施例中的防抖结构时，在压片组件通电后，丝线能够在电流的作用下收缩或者膨胀并带动簧片的至少一部分沿运动的方向移动。因此，通过调节电流的大小能够控制簧片的至少一部分能够沿X 轴和Y轴方向运动，从而实现防抖的目的。并且，由于在本实施例中防抖结构还具有滚珠组件，而现有技术中防抖结构通常使用的是IOS防抖支座。也就是说，现有的防抖结构在簧片运动的过程中簧片通过IOS防抖支座与基板组件接触，此时为平动摩擦。而在本实施例中由于滚珠组件与基板组件之间是滚动接触的，因此有效地降低了簧片的驱动阻力，进而提高了防抖结构的防抖补偿精度，使拍照或摄像获得更好的图像质量，同时，簧片达到指定的位置需要的电流更小，功耗更低。当然，在本申请中，也可以使用IOS防抖支座代替滚珠组件。
需要说明的是，在本申请中透镜驱动装置的第一弹性支撑组件40、第二弹性支撑组件80以及防抖结构之间一共具有四种组成形式。第一种形式为单一的只具有第一弹性支撑组件40的形式，此组成形式能够在实现自动对焦的同时还具有移轴式防抖的功能。第二种形式为在第一种形式的基础上增加第二弹性支撑组件80，并能够实现大行程的自动对焦。第三种形式为在第一种形式的基础上增加防抖结构，从而实现平移式防抖和移轴式防抖的双重防抖。第四种形式则同时包括第一弹性支撑组件40、第二弹性支撑组件80和防抖组件。并且，在第一种形式和第三种形式中，底座组件20不具有支撑架22。而在第二种形式和第四种形式中，底座组件20则具有支撑架22。并且还需要说明的是，当底座组件20具有支撑架22时，底座组件20的定位槽60和定位柱61设置在支撑架22远离第二弹性支撑组件80的一侧。当底座组件20不具有支撑架22时，底座组件20的定位槽60和定位柱61设置在本体部21上。并且，第一种形式和第三种形式的透镜驱动装置的第一弹性支撑组件、连接臂、连接环以及第一FPC板之间的位置关系如图7所示。第二种形式和第四种形式的透镜驱动装置的第一弹性支撑组件、连接臂、连接环以及第一FPC板之间的位置关系如图8所示。
具体地，透镜驱动装置还包括弹片90，弹片90设置在镜头座30与外壳10之间，为镜头座30提供向底座组件20一侧运动的复位力。通过这样设置，在第一弹性支撑体41以及第二弹性支撑体81未受到挤压结构的挤压力时，镜头座30是受到弹片90的作用力，并且镜头座30的受力方向指向底座组件20的一侧，也就是说在本申请中弹片90是向镜头座30提供预紧力，并且在第一弹性支撑体41和第二弹性支撑体81产生形变带动镜头座30完成对焦后，并且需要使镜头座30回复至对焦前的位置时，弹片90对镜头座30的作用力能够加快镜头座30的复位速度，从而能够提高透镜驱动装置的响应速度。
还需要指出的是，在本申请中，弹片90仅为镜头座30提供弹性力，因此弹片 90不需要连电，因此与传统的音圈马达相比，本申请中的透镜驱动装置不需要设计复杂的电路结构。
具体地，弹片90与镜头座30远离底座组件20的一端抵接，且底座组件20朝向镜头座30的一侧还具有固定柱23，弹片90与固定柱23连接。
具体地，固定柱23为多个，底座组件20的每个角部处分别设置有至少一个固定柱23。
在本申请的一个具体实施例中，弹片90包括挤压部和连接部。挤压部呈环形，且挤压部与镜头座30抵接；连接部为多个，多个连接部与多个固定柱23一一对应，且连接部的一端与挤压部连接，连接部的另一端与固定柱23连接。
从以上的描述中，可以看出，本发明上述的实施例实现了如下技术效果：
1、结构简单组装容易，电路走线简单，电路稳定。
2、没有磁铁不会产生对内或对外的磁干扰问题。
3、没有磁路设计问题，整个行程力度平均推力较磁电方式大，比磁电方式更有效率。
4、没有音圈马达的上、下弹簧设计，跌落和滚筒等测试不会有弹簧变形、镍或异物脱落问题。
6、弹性支撑体本身就有阻尼作用，不需外加阻尼胶。
7、可以使用塑料做马达外壳，对移动终端天线db增益有帮助。
8、可以做成不同外形结构的马达。
9、弹性支撑体还可有防尘圈的作用，防尘效果比磁电方式更好。
10、相同镜头直径的马达完成品尺寸面积可以比磁电方式尺寸小。
显然，上述所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
