Description

透镜驱动装置、摄像装置及移动终端 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，音圈电机在存在结构及性能不稳定的问题。例如：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。
因此，现有技术中存在摄像装置的音圈马达的使用性能差的问题。

进一步地，底座朝向镜头座的一侧设置有绕线结构，驱动线圈通过绕线结构固 定在底座上。
进一步地，绕线结构包括多个绕线板，多个绕线板沿底座的周向间隔设置，驱动线圈顺次经过多个绕线板并沿底座的周向连续绕设多圈。

进一步地，端脚组件设置在底座上。
进一步地，驱动磁石设置在弹性支撑体的外侧壁上。
进一步地，弹性支撑体的外侧壁具有安装座，安装座朝向驱动线圈一侧的表面为平面，驱动磁石设置在平面上。
进一步地，驱动磁石嵌埋在弹性支撑体的内部。
进一步地，弹性支撑体具有预埋槽，驱动磁石容置在预埋槽内。
进一步地，弹性支撑体呈环状，且弹性支撑体与镜头座的周侧套接。
进一步地，镜头座包括：筒状结构，筒状结构的内部用于容置镜头；抵接凸缘，抵接凸缘设置在筒状结构远离底座的一端，弹性支撑体套设在筒状结构的外周侧，且弹性支撑体远离底座的一端与抵接凸缘抵接。
进一步地，沿Z轴方向弹性支撑体的中间部分的直径大于弹性支撑体的两端的直径。
进一步地，弹性支撑体由硅胶材料或者橡胶材料制成。
进一步地，弹性支撑体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。
进一步地，端脚组件包括至少两个接线端脚，底座朝向镜头座的一侧具有接线凸起，其中一个接线端脚的一端由底座远离接线凸起的一端分别穿过底座和接线凸起并伸出接线凸起。
进一步地，底座朝向镜头座的一侧具有支撑凸环，且弹性支撑体的至少一部分与支撑凸环连接。
进一步地，底座朝向镜头座的一侧还具有至少一个导向柱，抵接凸缘上设置有至少一个与导向柱配合的导向孔。
进一步地，透镜驱动装置还包括弹片，弹片设置在镜头座与外壳之间，为镜头座提供向底座一侧运动的复位力。
进一步地，弹片与镜头座远离底座的一端抵接，且底座朝向镜头座的一侧还具 有固定柱，弹片与固定柱连接。

根据本发明的另一方面，提供了一种移动终端，移动终端包括上述的摄像装置。
应用本发明的技术方案，本申请中的透镜驱动装置包括外壳和底座，外壳罩设在底座上并与底座之间形成容置空间，透镜驱动装置还包括设置在容置空间内的镜头座、弹性支撑体、驱动磁石、驱动线圈以及端脚组件。镜头座活动设置在容置空间的内部；驱动磁石为多个，驱动磁石的至少一部分设置在弹性支撑体的周向侧壁上；驱动线圈通电以使驱动磁石运动，驱动磁石挤压弹性支撑体变形并带动镜头座沿Z轴方向运动；驱动线圈与端脚组件电连接。
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，所以能够使移动终端的镜头安装在镜头座上，并且由于还具有弹性支撑体，所以能够通过弹性支撑体的形变带动镜头座移动，从而带动镜头沿Z轴方向运动，进而实现自动调焦功能。而在本申请中由于还具有驱动线圈和驱动磁石，并且驱动磁石设置在弹性支撑体上，所以通过驱动线圈和驱动磁石的相互感应能够使得驱动磁石产生运动，从而能够使驱动磁石对弹性支撑体产生挤压。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电路结构更加简单。同时还不存在音圈马达的上、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。又由于本申请中的弹性支撑体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。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音圈马达使用性能差的问题。

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。
在本发明中，在未作相反说明的情况下，使用的方位词如“上、下、顶、底”通常是针对附图所示的方向而言的，或者是针对部件本身在竖直、垂直或重力方向上而言的；同样地，为便于理解和描述，“内、外”是指相对于各部件本身的轮廓的内、外，但上述方位词并不用于限制本发明。
为了解决现有技术中摄像装置的音圈马达使用性能差的问题，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4所示，本申请中的透镜驱动装置包括外壳10和底座20，外壳10罩设在底座20上并与底座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、弹性支撑体40、驱动磁石41、驱动线圈42以及端脚组件43。镜头座30活动设置在容置空间的内部；驱动磁石41为多个，驱动磁石41的至少一部分设置在弹性支撑体40的周向侧壁上；驱动线圈42通电以使驱动磁石41运动，驱动磁石41挤压弹性支撑体40变形并带动镜头座30沿Z轴方向运动；驱动线圈42与端脚组件43电连接。
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，并且由于还具有弹性支撑体40，所以能够通过弹性支撑体40的形变带动镜头座30移动，从而带动镜头沿Z轴方向运动，进而实现自动调焦功能。而在本申请中由于还具有驱动线圈42和驱动磁石41，并且驱动磁石41设置在弹性支撑体40上，所以通过驱动线圈42和驱动磁石41的相互感应能够使得驱动磁石41产生运动，从而能够使驱动磁石41对弹性支撑体40产生挤压。并且，由于本申请中不再需要与驱动磁石41和驱动线圈42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电路结构更加简单。同 时还不存在音圈马达的上、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。又由于本申请中的弹性支撑体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。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音圈马达使用性能差的问题。
需要说明的是，在本申请中弹性支撑体40是设置在镜头座30与底座20之间的，并且弹性支撑体40的两端分别与镜头座30和底座20抵接。
并且，在本申请中，外壳10上与底座20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，底座20朝向镜头座30的一侧设置有绕线结构70，驱动线圈42通过绕线结构70固定在底座20上。通过设置绕向结构能够有效地保证驱动线圈42的稳定性，并且保证驱动线圈42与驱动磁石41能够产生稳定的感应。
在本申请的一个具体实施例中，绕线结构70包括多个绕线板71，多个绕线板71沿底座20的周向间隔设置，驱动线圈42顺次经过多个绕线板71并沿底座20的周向连续绕设多圈。通过这样设置，在将驱动线圈42绕向的绕线板71上之后，能够形成一个完整的驱动线圈42，并且这个驱动线圈42能够与不同的驱动磁石41对应，从而能够同时与不同的驱动磁石41产生感应。并且，需要指出的是，此时所有的驱动磁石41均是与驱动线圈42的内周侧相对的。
在本申请的另一个实施例中，绕线结构70包括多个绕线板71，多个绕线板71沿底座20的周向间隔设置，驱动线圈42包括多个驱动子线圈，多个驱动子线圈一一对应绕设在多个绕线板71上，且多个驱动磁石41与多个驱动子线圈一一对应设置。在本实施例中，多个驱动子线圈与多个驱动磁石41的数量是相等的，并且驱动子线圈与驱动磁石41是对应设置的。也就是说在上面的实施例中只有一个线圈，并且一个线圈与多个驱动磁石41对应，而在本实施例中是有多个线圈的。并且，还需要注意的是，在本实施例中绕线板71的数量同样是与驱动磁石41的数量相同的，并且每个驱动子线圈均缠绕在其中一个相对应的绕线板71上。需要指出的是，在上面的实施例中，绕线板71可以是不与驱动磁石41对应的是，而在本实施例中则是需要绕线板71与磁石相对设置。
具体地，端脚组件43设置在底座20上。并且，驱动磁石41设置在弹性支撑体40的外侧壁上。
在本申请的一个具体实施例中，弹性支撑体40的外侧壁具有安装座80，安装座80朝向驱动线圈42一侧的表面为平面，驱动磁石41设置在平面上。通过这样设 置，当驱动线圈42与驱动磁石41产生感应时，驱动磁石41能够通过安装座80的平面对弹性支撑体40进行挤压，这样不仅能够保证弹性支撑体40与驱动磁石41之间的稳定性，以保证驱动磁石41相对弹性支撑体40不会出现偏斜，而且还能够保证弹性支撑体40的受力更加均匀，以保证弹性支撑体40能够沿预设的方向进行变形。因此，通过这样设置有效地保证了透镜驱动装置的使用性能。
当然，在本申请中也可以将驱动磁石41嵌埋在弹性支撑体40的内部。或者是在弹性支撑体40上设置预埋槽，并将驱动磁石41容置在预埋槽内。在本申请中，对于驱动磁石41的安装方式，只要保证驱动磁石41能够沿预设的方向对弹性支撑体40进行挤压，并且能够保证驱动磁石41不会相对透镜支撑体产生滑动，或者说是保证驱动磁石41与弹性支撑体40之间的稳定性即可。
可选地，弹性支撑体40呈环状，且弹性支撑体40与镜头座30的周侧套接。通过这样设置，不仅能够方便镜头座30与弹性支撑体40的连接，可以还可以保证弹性支撑体40在受到驱动磁石41的挤压力而产生形变后，镜头座30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，也可以将弹性支撑体40看成是环状的，并且通过这样设置可以使得弹性支撑体40能够起到防尘的作用，从而提高透镜驱动装置的密封性能。
当然，需要指出的是，在本申请中弹性支撑体40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弹性支撑体40设置成其他形状，例如正多边形的筒状结构31。
在本申请的一个具体实施例中，镜头座30包括筒状结构31和抵接凸缘32。筒状结构31的内部用于容置镜头60；抵接凸缘32设置在筒状结构31远离底座20的一端，弹性支撑体40套设在筒状结构31的外周侧，且弹性支撑体40远离底座20的一端与抵接凸缘32抵接。在本实施例中，设置筒状结构31不仅能够容置移动终端的镜头，而且还能够使弹性支撑体40可以更加容易地套设在镜头座30上，并且保证弹性支撑体40与筒状结构31更加贴合。而通过设置抵接凸缘32则可以保证弹性支撑体40的一端能够与抵接凸缘32抵接，这样能够保证弹性支撑体40在受力产生形变后，弹性支撑体40能够带动镜头座30一同运动，而不会出现弹性支撑体40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。
可选地，沿Z轴方向弹性支撑体40的中间部分的直径大于弹性支撑体40的两端的直径。在本申请中，这样设置的目的是弹性支撑体40主要是通过中间部分的形变来产生沿Z轴方向的延伸，从而使弹性支撑体40能够带动镜头座30实现大行程 驱动。并且，通过这样设置，在弹性支撑体40受力产生形变后，弹性支撑体40中间部分的直径不会过小，从而保证弹性支撑在受到挤压力后不会出现偏斜，进而保证弹性支撑体40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。
可选地，弹性支撑体40由硅胶材料或者橡胶材料制成。通过这样设置，可以降低透镜驱动装置的整体重量，从而在驱动透镜运动时需要的力更小，进而能够提高透镜驱动装置的灵敏度。
具体地，弹性支撑体40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，能够在保证弹性支撑体40的形变性能外，还能够通过填充的液体或者气体来保证弹性支撑体40的支撑效果，并使弹性支撑在不受挤压力时能够具有一定的形状。
可选地，端脚组件43包括至少两个接线端脚431，底座20朝向镜头座30的一侧具有接线凸起21，其中一个接线端脚431的一端由底座20远离接线凸起21的一端分别穿过底座20和接线凸起21并伸出接线凸起21。
具体地，底座20朝向镜头座30的一侧具有支撑凸环22，且弹性支撑体40的至少一部分与支撑凸环22连接。在本申请中，支撑凸环22不仅起到为镜头座30和弹性支撑体40提供安装定位的作用，而且还能够起到密封和防止弹性支撑体40出现弯折或者偏斜的作用。
具体地，底座20朝向镜头座30的一侧还具有至少一个导向柱23，抵接凸缘32上设置有至少一个与导向柱23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23之间始终是保持连接的。也就是说，在本申请中，设置导向柱23的目的是通过导向孔321与导向柱23的配合，使得镜头座30能够套设在导向柱23上，并且在镜头座30的运动过程中，通过导向柱23为镜头座30的运动提供导向作用，从而能够防止镜头的光轴出现偏斜。
可选地，导向柱23为多个，并且导向柱23沿支撑凸环22的外周侧间隔设置。需要说明的是，在本申请的一个具体实施例中，导向柱23为多个并设置在底座20的角部处，并且底座20的每个角部处均设置有一个导向柱23。
具体地，透镜驱动装置还包括弹片50，弹片50设置在镜头座30与外壳10之间，以为镜头座30提供向底座20一侧运动的复位力。通过这样设置，在弹性支撑体40未受到驱动磁石41的挤压力时，镜头座30是受弹片50的作用力的，并且镜头座30的受力方向指向底座20的一侧，也就是说在本申请中弹片50是向镜头座 30提供预紧力的，并且在弹性支撑体40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50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50仅为镜头座30提供弹性力，因此弹片50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。
在本申请的一个具体实施例中，弹片50与镜头座30远离底座20的一端抵接，且底座20朝向镜头座30的一侧还具有固定柱24，弹片50与固定柱24连接。
可选地，固定柱24为多个，底座20的每个角部处分别设置有至少一个固定柱24。
在本申请的一个具体实施例中，弹片50包括：挤压部51，挤压部51呈环形，且挤压部51与镜头座30抵接；连接部52，连接部52为多个，多个连接部52与多个固定柱24一一对应，且连接部52的一端与挤压部51连接，连接部52的另一端与固定柱24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。
3、弹性支撑体本身就有阻尼作用，不需外加阻尼胶。
4、可以做成不同外形结构的马达。
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。
