Description

透镜驱动装置、摄像装置及移动终端 技术领域
本申请涉及摄像装置领域，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。
因此，现有技术中存在摄像装置的音圈马达使用性能差的问题。

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组件，所以能够通过弹性支撑组件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。也就是说，在本申请中，通过透镜驱动装置的弹性支撑组件代替了原有的音圈马达中的驱动线圈和驱动磁石部分。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。又由于本申请中的弹性支撑组件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，由于仅通过弹性支撑组件对镜头座进行驱动，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申请。
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。
在本申请中，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申请。
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和弹性支撑组件40。镜头座30活动设置在容置空间的内部；弹性支撑组件40支撑在镜头座30与底座20之间或者支撑在镜头座30与外壳10之间，弹性支撑组件40通电以使弹性支撑组件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。
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组件40，所以能够通过弹性支撑组件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。也就是说，在本申请中，通过透镜驱动装置的弹性支撑组件40代替了原有的音圈马达中的驱动线圈和驱动磁石部分。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音圈马达使用性能差的问题。
在本申请的下述实施例中，弹性支撑组件40是设置在镜头座30与底座20之间的。
需要说明的是，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。
在本申请的一个具体实施例中，弹性支撑组件40包括弹性支撑体41和挤压结构42。挤压结构42通电以向弹性支撑体41提供挤压力，当弹性支撑体41受挤压结构42挤压时，弹性支撑体41产生形变并带动镜头座30沿Z轴方向运动。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时，挤压结构42会通电并对弹性支撑体41产生挤压，从而通过弹性支撑体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。当然，在本申请中也可以将挤压结构42设置成其他形式，只要能够控制挤压结构42可以对弹性支撑体41进行挤压即可。
需要指出的是，在本申请中通过设置弹性支撑体41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。
可选地，弹性支撑体41呈环状，且弹性支撑体41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41的连接，可以还可以保证弹性支撑体41在受到挤压结构42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41看成是环状的，并且通过这样设置可以使得弹性支撑体41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41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41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41套设在筒状结构31的外周侧，且弹性支撑体41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41可以更加容易地套设在镜头座30上，并且保证弹性支撑体41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41的一端能够与抵接凸缘32抵接，这样能够保证弹性支撑体41在受力产生形变后，弹性支撑体41能够带动镜头座30一同运动，而不会出现弹性支撑体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。
可选地，沿Z轴方向弹性支撑体41的中间部分的直径大于弹性支撑体41的两端的直径。在本申请中，这样设置的目的是弹性支撑体41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41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41受力产生形变后，弹性支撑体41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41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41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。
当然，在本申请中由于不需要考虑电磁干扰的问题，所以通过可以用塑料材料制作透镜驱动装置的，从而能够提高移动终端天线的db增益。
对于外壳10的材质来说，传统的音圈马达，考虑到增强磁场强度，外壳10通常需要用到磁性材料，以达到挡磁聚磁的作用。而本申请中的外壳10可采用磁性、非磁性金属、或者非金属材料，如塑料材质均可以，外壳10材质选择的灵活性强。
而对于外壳10的形状来说，传统的音圈马达，考虑到磁石、线圈的配合组装工艺，特殊的形状马达，比如圆形马达，需要特殊形状的磁石，才能起到磁感应驱动的效果，但特殊形状的磁石对工艺提出了比较高的要求，难以实现。而本申请中的外壳10则可以实现不同外形结构的马达。
具体地，弹性支撑体41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41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41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，挤压结构42设置在弹性支撑体41的外周侧，或者弹性支撑体41上设置有预埋槽，挤压结构42的至少一部分嵌埋在预埋槽内。在本申请的一个具体实施例中，挤压结构42设置在弹性支撑体41的外周侧。
在本申请的一个具体实施例中，挤压结构42包括SMA丝线421和端脚组件422。SMA丝线421绕设在弹性支撑体41的周向外侧壁上；端脚组件422设置在底座20上，且SMA丝线421的两端分别与端脚组件422连接。在本实施例中SMA丝线421的输入、输出端与端脚组件422进行电连接，并且SMA丝线421与端脚组件422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SMA丝线421的输入、输出端与端脚组件422之间的连接稳定性即可。
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41未受到挤压结构42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41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。
在本申请中端脚组件422向SMA丝线421通电，并且SMA丝线421在通电后发热，根据SMA丝线421热缩冷胀的特性，SMA丝线421能够对绕设的弹性支撑体41施加径向压力而使弹性支撑体41塑性变形，由于弹性支撑体41的上、下端为自由端，因而弹性支撑体41的变形方向为长度方向Z轴，因弹性支撑体41下端与底座20抵接，故弹性支撑体41的Z轴变形即为通过挤压镜头座30使镜头座30沿Z轴移动，弹性支撑体41不同程度的变形与弹片50在Z轴方向的压力的合力形成镜头座30的驱动行程，进而实现镜头自动对焦。
可选地，端脚组件422包括至少两个接线端脚4221，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4221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41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41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41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。
在本申请的一个未图示的实施例中，弹性支撑体41为多个，挤压结构42为多个，多个挤压结构42与多个弹性支撑体41一一对应设置，且多个弹性支撑体41沿镜头座30的周向间隔设置。通过这样设置，可以通过对弹性组件的不同设置方式，使得透镜驱动装置的内部空间具有可变性，从而能够更加灵活地对透镜驱动装置的内部空间进行布局。
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，本申请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。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施方式能够以除了在这里图示或描述的那些以外的顺序实施。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
