Description

照相机用透镜驱动装置、照相机及电子设备 技术领域
本发明涉及照相机用透镜驱动装置领域，尤其涉及一种防止图像抖动为得到清晰的图像的透镜驱动装置、照相机及电子设备。
 背景技术
随着拍摄技术的迅速发展，对照片品质的要求变得比以往高，特别是在拍摄夜景时，为了提高暗处的拍摄品质，需要追加明亮的透镜或图像抖动防止功能，使用了图像抖动校正的透镜驱动装置被广泛地应用于许多拍摄装置及便携式电子设备。
适用于通常的便携式电子设备的透镜驱动装置的驱动机构一般由线圈和磁钢形成，线圈固定于透镜架的外周。在向线圈施加电流时，由于电磁力的作用，线圈使透镜架移动而沿着透镜的光轴方向移动，从而能够进行对焦。但是，在用户手持电子设备的同时进行拍摄时，无法避免基于手抖的透镜驱动装置的抖动。因此，存在透镜向与透镜的光轴正交的方向不断移动的情况。这样，在透镜驱动装置中，不会抑制拍摄图像的紊乱，拍摄到的图像的质量降低。
另外，在一般的线式手抖校正装置中，透镜的移动和调整方向相对于光轴为平行移动，相对于光学传感器也是平行移动，因此光学校正量在换算照相机的抖动角度或抖动移动量时存在校正量不足的担忧，并且为了增加向与光轴正交的方向的抖动校正量，存在与旋转式手抖校正装置相比透镜驱动装置的最大外形进一步扩大的可能性。
现状的旋转轴式手抖动校正装置在透镜驱动装置的上部双重地设置金属的悬架且设置球轴承，是能够从四角分别自由地以双轴的对角线旋转的构造，但必须以位于远离驱动用电路的高位置的保持部件为起点来驱动透镜模块，在需要刚性高的保持方法、或无法以透镜的大致主点为起点的情况下，存在无法对光学传感器进行最有效的校正的可能性。
因此，需要提供一种能够解决以上的课题的新的透镜驱动装置。

 本发明的实施方式
下面，一边参照图面一边对本发明进行详细说明。
图1～图5是表示本发明的透镜驱动装置100的附图。
透镜驱动装置100具备壳体10、透镜模块30、电路板固定用基座40、支承部件41、磁性体60以及驱动线圈70。
在壳体10具有收容空间13，壳体10具备固定用基座11、用于与固定用基座11配合地形成收容空间13的罩12、以及电路板80。
电路板固定用基座40具备固定于电路板固定用基座40的电路板80以及驱动线圈70。
支承部件41以透镜模块30能够沿着与透镜的光轴正交的方向相对于电路板固定用基座40自如地转动的方式对透镜模块30和第二支承框架21进行支承。第二支承框架21上可以设置有固定支承部件41的对支承部件41的方向进行限制的槽42。
支承部件41可以是轴销。轴销即支承部件41至少设置4个，与此相对，设置于电路板固定用基座40及透镜模块30上，并且一同通过透镜模块的主点附近，即配置在相对于主点附近成为大致对称的位置，通过对设置于电路板固定用基座40的两个支承部件41和支承部件的方向进行限制的槽42，对转动的轴进行限制，通过轴销即支承部件41的滚动，透镜模块30能够在基于与透镜的光轴正交的方向的、被限制的第一旋转光轴方向43及被限制的第二旋转光轴44内自如地转动。
另外，相对于光轴方向，按照电路板固定用基座40、4个支承部件41、第二支承框架21、透镜模块30以及设置于透镜模块30上的第一支承框架20的顺序进行组装，通过向设置于透镜模块30的支承部件41和设置于电路板固定用基座40及第二支承框架21的支承部件进行吸引限制的磁性体60的磁作用，这些部件以无论朝向哪个方向都不脱离的方式在光轴方向上被吸附。
磁钢61安装并固定于设置在透镜模块30上的第一支承框架20。
弹簧片50连接透镜模块30和电路板固定用基座40。
弹簧片50使用磁性材料，能够通过向支承部件41和设置于电路板固定用基座40及第二支承框架21的支承部件进行吸引限制的磁性体60的磁作用，以这些部件无论朝向哪个方向都不脱离的方式在光轴方向上具有吸附力，在透镜模块向光轴方向垂直方向转动时具有向光轴中心拉拽的功能。
就透镜驱动装置100而言，磁轭91至少设置两个且相对于光轴大致旋转对称，磁轭91安装并固定于第一支承框架20，并且在与磁轭91同样地至少设置两个且相对于光轴大致旋转对称的磁钢61和透镜模块30转动时，具有向转动中心拉拽的功能。
驱动线圈70设置于在电路板固定用基座40固定的电路板80，分别对应地设置于磁钢61的外侧。
驱动线圈70可以是与安装并固定于电路板固定用基座40上的电路板80一体化的线圈绕组，也可以是直接形成于电路板80上的导电性图案。通过驱动线圈70与磁钢61之间的电磁作用，第一支承框架20能够沿着与透镜的光轴正交的方向相对于电路板固定用基座40旋转移动，因此实现了能够调整透镜的光轴相对于透镜的大致主点转动的机构。
在透镜驱动装置100还设置有电路板80。
电路板80与驱动线圈70连接。
以与驱动线圈70对置的方式，磁钢61相对于各个驱动线圈设置有两个，并且配置在相对于透镜的光轴大致旋转对称、即相对于中心线大致旋转对称的位置。
驱动线圈70与设置于电路板固定用基座40的与外部连接的连接端子14连接，但也可以与具有驱动用电路的磁检测元件连接，具有第二驱动用电路的磁检测元件81为一个例子，也可以是兼磁检测的驱动IC。具有第二驱动用电路的磁检测元件81位于与磁钢61对置的位置，能够检测与透镜模块40一起移动的磁钢61的位置。
在透镜的光轴因手抖而移动的情况下、或者存在移动的倾向的情况下，能够使电流流入设置在透镜模块的重心位置31的水平附近的驱动线圈70，驱动线圈70被固定，因此基于作用力及反作用力的原理，透镜模块30及第二支承框架21能够分别相对于移动物即透镜模块30的大致主点高效地保持均衡的同时转动，另外能够抑制透镜的光轴的移动倾向。因此，能够对透镜的光轴的移动进行调整。
上述透镜驱动装置100例如可以用于图8所示的所谓的智能手机、所谓的功能手机、或者平板设备等便携信息设备200用的拍摄装置300。
根据本发明的透镜驱动装置100，能够实现对透镜的光轴的移动的调整，因此能够达成抖动防止的目的，能够提高拍摄图像的品质。
以上仅是本发明的优选的实施方式，本发明的保护范围并不限定于上述实施方式，本领域的技术人员基于本发明所公开的内容而作出的同等的修改或变形全部包含在本申请的权利要求书所记载的本发明中。
