Description

光学变焦马达、摄像装置及光学变焦马达的组装方法 技术领域
本申请涉及潜望式对焦装置领域，具体而言，涉及一种光学变焦马达、摄像装置及光学变焦马达的组装方法。
背景技术
近年来随着市场需求，手机摄像头为适应新的发展趋势，具有高像素、大光圈、超薄型的要求。
现有的自动对焦装置均是利用音圈马达同镜头以及影像传感器、电路板累加高度形成，由于手机像素的提高以及产品高度要求越来越薄，现有技术在产品的使用上出现瓶颈。大光圈以及高像素的镜头整体的光学高度比较高，造成现有累计的产品高度无法满足超薄的手机机身的需求。同时由于影像传感器的组装会出现偏差，造成光线中心和影像传感器中心无法重合，影响了影像传感器的成像质量，导致最终输出的照片达不到最佳的效果。
由于手机厚度的限制，采用常规竖向放置(即在手机表面上朝向外部)的手机摄像头焦距较小，光学变焦能力有限。而本申请的潜望式摄像头区别于传统镜头的竖向排列方式，在手机内横向排放，并增加了光学转换部件，由光学变焦马达、镜头组、棱镜等组成，以特殊的光学三棱镜让光线折射进入镜头组，实现成像，能够达到较高的光学变焦倍数，使镜头能够清晰拍摄到更远处的景物。潜望式结构，应用到智能手机上具有良好的运用前景。
在此，本申请旨在通过设计出一种具潜望式功能的光学变焦马达，配以棱镜部分的功能辅助，最终实现将马达平行放置在手机上，进一步使得手机高度得以大大降低，实现超薄机身及高质量光学变焦成像的效果。

需要指出的是，本申请中的摄像装置包括但并不限于具有拍照功能的智能手机。并且，在将本申请中的光学变焦马达使用在智能手机上时，不仅可以提高智能手机的相机模块的使用性能，而且还能够有效地减少智能手机的整体厚度，并且能够有效地解决智能手机后置摄像头外凸的问题，即解决智能手机的后置摄像头突出于智能手机的后壳。
还需要说明的是，本申请中的摄像装置除了应用在手机领域外，还可以应用在平板、电脑、汽车电子等微型影像照相领域。
如图1至图10所示，本申请中的光学变焦马达包括外壳10、底座20、透镜支撑体30、多个驱动磁石40、多个驱动线圈50、多个侧向磁石60以及多个侧向线圈70。底座20设置在外壳10的下方并与外壳10之间形成容置空间，外壳10包括顶壁111和周向侧壁112，顶壁111与底座20相对设置，且顶壁111通过周向侧壁112与底座20连接，周向侧壁112的一个侧壁上具有开口部113；透镜支撑体30活动设置在容置空间内；驱动磁石40设置在透镜支撑体30上；驱动线圈50设置在底座20上且对应驱动磁石40，驱动线圈50通电以使透镜支撑体30向靠近或远离开口部113的方向运动；周向侧壁112的一组相对设置的两个侧壁上分别各设置有至少一个侧向磁石60，且侧向磁石60和开口部113分别设置在不同的侧壁上；侧向线圈70设置在透镜支撑体30上，且多个侧向线圈70对应多个侧向磁石60设置。
使用上述结构的光学变焦马达时，由于底座20的周向侧壁112的一个侧壁上具有开口部113，所以与传统的开口设置在顶部的光学变焦马达相比在将本申请中的光学变焦马达安装在摄像装置上时，可以通过改变光学变焦马达的安装方向来减少摄像装置的整体厚度，同时这样设置还能够提高平行于手机方向的摄像装置的可变焦驱动空间范围，为清晰捕获更远处景物创造了有利条件，可获得更为完美的图像成像效果。又由于在本申请中分别设置有多个驱动磁石40、多个驱动线圈50、多个侧向磁石60以及多个侧向线圈70，所以通过驱动磁石40和驱动线圈50的配合能够驱动透镜支撑体30在容置空间中移动，达到驱动镜头的光学变焦的目的。而通过侧向磁石60和侧向线圈70的配合能够通过驱动透镜支撑体30来调整透镜支撑体30相对开口部113的位置，从而保证了光学变焦马达的防抖性能。因此，达到了驱动镜头的光学变焦目的，同时具有有效的防抖功能，而且使用本申请的结构来有效地降低摄像装置的整体厚度，解决了手机厚度的限制问题，克服了常规竖向放置即在手机表面上朝向外部的摄像头所导致可变焦范围狭窄，光学变焦能力不足的问题。
需要说明的是在本申请中，外壳10的一组相对设置的侧壁上可以均设置有开口部113，且另一组相对设置的侧壁上设置有侧向磁石60。
需要指出的是，在本申请中透镜支撑体30的所有运动的运动方向均是与底座20平行的。并且在本申请中侧向线圈70与侧向磁石60之间的安装位置是可以互换的，但需要说明的是，互换后的侧向线圈70的固定及电气导通方式会有一定的复杂性。另外，互换后的侧向磁石60会一定程度存在对底座20上的位置传感器200造成磁气干扰，影响反馈精度。
如图11所示，还需要说明的是，在将本申请中的光学变焦马达以及使用在具有拍照功能的手机上时，需要特别注意光学变焦马达的安装方向。在进行组装时，需要将光学变焦马达与手机后壳平行设置或者与手机屏幕平行设置，也有是说当使用本申请中的光学变焦马达时，在驱动透镜支撑体30进行对焦时，透镜支撑体30的运动方向是与手机后壳或者手机屏幕是平行的。此时，为了保证手机的相机模块的正常使用，在实际摄像过程中，除了需要使用本申请中的光学变焦马达的同时，还要搭配棱镜马达100与棱镜系统一同使用，即在镜头末端增加一个45度的棱镜采光的驱动系统。其结构特征为，棱镜马达100的入射面平行于手机后壳或者手机屏幕并能够对待拍摄的目标进行采集，并且棱镜马达100的反射面对准屏蔽罩11的开口部113即镜头。具体的实现途径为，沿着一条与机身平行的光学轴线对准镜头，然后通 过棱镜的反射将进入摄像头内的光线反射到光学变焦镜头和图像传感器上，如此一来即可创造出比传统摄像头的竖向安装方向即在手机表面上朝向外部更长的等效焦距。
具体地，透镜支撑体30悬浮设置在底座20上方，且透镜支撑体30与底座20之间具有安装间隙。由于透镜支撑体30在运动的过程中其运动的方向相对于底座20始终是平行的，所以通过设置安装间隙可以有效地减少透镜支撑体30与底座20之间的摩擦，进而能够有效地保证光学变焦马达的使用寿命。并且，通过这样设置还可以减少底座20对透镜支撑体30的运动产生的影响，进而保证透镜支撑体30的运动更加灵敏。
具体地，光学变焦马达还包括多个悬丝80，底座20位于外壳10内的部分的各角部处均对应设置有一个悬丝80，透镜支撑体30的多个角部与多个悬丝80对应支撑，以使透镜支撑体30悬浮设置。通过设置悬丝80不仅能够实现光学变焦马达中的电连接，而且由于透镜支撑体30是悬浮设置在底座20上方的，所以通过悬丝80能够保证透镜支撑体30与底座20之间的连接，并且还可以通过悬丝80对透镜支撑体30的运动进行一定的限位作用以及对透镜支撑体30提供支撑力。
具体地，外壳10包括屏蔽罩11、框架12、多个磁石背板13。屏蔽罩11具有顶壁111和周向侧壁112：框架12位于容置空间内且与顶壁111连接，侧向磁石60位于框架12靠近底座20的一侧；磁石背板13与侧向磁石60对应设置，且磁石背板13位于周向侧壁112与侧向磁石60之间，磁石背板13是隔磁材料制成的。通过设置屏蔽罩11，可以有效地对光学变焦马达中的其他组件起到保护作用。而通过设置框架12和多个磁石背板13可以有效地对侧向磁石60进行固定。并且，通过设置磁石背板13还可以对侧向磁石60起到隔磁的作用，这样不仅能够保证侧向磁石60的使用效果，而且还可以减少侧向磁石60对摄像装置的其他组件产生影响。
可选地，框架12与侧向磁石60卡接。
可选地，磁石背板13与侧向磁石60卡接。
可选地，磁石背板13与框架12连接。
在本申请的一个具体实施例中，框架12与磁石背板13连接，并且侧向磁石60设置在磁石背板13上并通过框架12和磁石背板13分别对侧向磁石60进行卡接，在使得侧向磁石60保持固定的同时还可以使得侧向磁石60对准侧向线圈70。
具体地，磁石背板13的至少三个边缘处具有翻边131，以围成用于容置侧向磁石60的腔体，且磁石背板13的至少一个边缘处设置有卡接凸起132，卡接凸起132与框架12的卡槽121配合；或者框架12具有朝向底座20的卡口122，侧向磁石60的边缘卡接在卡口122处。通过这样设置，可以有效地保证磁石背板13或者框架12对侧向磁石60的固定效果，有效地保证了侧向磁石60的稳定性，并且在光学变焦马达受到撞击或者震动时，可以保证侧向磁石60与屏蔽罩11之间不会出现相对晃动。
可选地，翻边131的宽度等于侧向磁石60的厚度。通过这样设置，可以有效地对侧向磁石60起到保护作用，并且通过这样设置还能够对透镜支撑体30的运动起到一定的限位作用。翻边131能够很好地托住侧向磁石60。进一步可选地，翻边131的外伸端向上翻折，以包裹住侧向磁石60的边缘，以防止侧向磁石60脱出。
当然，根据实际的使用情况，翻边131的宽度也可以小于或者大于侧向磁石60的厚度，但是需要保证磁石背板13对侧向磁石60的固定效果。
在本申请的一个具体实施例中，框架12与屏蔽罩11之间通过焊接连接。
如图12所示，在本申请的另一个具体的实施例中，框架12远离透镜支撑体30的一侧具有胶水槽123，框架12与屏蔽罩11之间通过胶水粘接。通过使用胶水粘接的方式，可以更加容易地使屏蔽罩11与框架12之间保持连接。
具体地，如图7所示，底座20具有PCB板21，驱动线圈50与PCB板21电连接，底座20的至少一部分伸出至外壳10的外侧，以使PCB板21的引脚25裸露在外壳10的外侧。在这里需要指出的是，由于在本申请中光学变焦马达安装在摄像装置内部的方式与传统的光学变焦马达安装在摄像装置中的方式是不同的，在本申请中PCB板21以及底座20伸出外壳10的外侧的部分是不具有弯折部分的，这样设置可以有效地减少光学变焦马达的整体厚度。
可选地，周向侧壁112远离顶壁111的边缘处预留有至少一个让位缺口114，底座20经让位缺口114处伸出至外壳10的外侧。通过这样设置，可以使光学变焦马达通过底座20以及PCB板21伸出外壳10的外侧的部分与摄像装置实现电连接。
如图1和图2所示，在本申请的一个具体实施例中屏蔽罩11具有三个让位缺口114，且具有让位缺口114的周向侧壁112与具有开口部113的周向侧壁112不是同一侧壁。

需要说明的是，如图21所示，在本申请中容置凹槽34内还设置有注胶孔342，从而可以通过向注胶孔342中注胶以增强对导磁板35的固定。
具体地，容置凹槽34的槽底还设置有导磁板35，驱动磁石40位于导磁板35与驱动线圈50之间。通过设置导磁板35，这样能够在不影响驱动磁石40和驱动线圈50之间的感应的同时还能够对驱动磁石40起到一定的固定作用，从而能够有效地防止驱动磁石40从透镜支撑体30上掉落。
需要说明的是，此时导磁板35与透镜支撑体30可以是一体结构。
当然，如图22和图23所示，导磁板35与透镜支撑体30也可以是分体结构，此时导磁板35的边缘处设置有安装槽36，透镜支撑体30具有嵌入安装槽36内的安装凸起341。
具体地，多个驱动线圈50为两组，两组驱动线圈50与两个容置凹槽34一一对应设置，且各组内均设置有至少两个驱动线圈50，且同组内的多个驱动线圈50彼此电连接。通过这样设置，能够保证两组驱动线圈50可以分别与不同的容置凹槽34中的驱动磁石40产生感应，从而保证驱动磁石40和驱动线圈50之间的感应更加灵敏。
具体地，各组内均有两个驱动线圈50，且所有驱动线圈50分别位于底座20的四个角部处，其中一组的两个驱动线圈50通电时的电流方向相反。并且另一组的两个驱动线圈50通电时的电流方向相同。这两组驱动线圈50分别与其对应驱动磁石40相配合，以满足左手定则。

具体地，PCB板21具有多个与悬丝80配合的第一连通孔211。
具体地，底座20的座体22具有多个与悬丝80配合的第二连通孔221。

具体地，透镜支撑体30设置有多个定位缺口31，各定位缺口31内设置有至少一个挂线柱38，多个侧向线圈70套设在挂线柱38上并与多个定位缺口31对应卡接。需要说明的是，当侧向线圈70安装在挂线柱38上之后，挂线柱38是突出于侧向线圈70的，这样可以通过挂线柱38对侧向线圈70进行保护，防止对侧向线圈产生撞击。
如图16所示，透镜支撑体30对应侧向线圈70的位置处设置有至少一个点胶孔381。通过这样设置可以进一步保证侧向线圈70安装在透镜支撑体30上的稳定性。
可选地，透镜支撑体30的角部处具有至少一个限位角39。通过这样设置，可以有效地对透镜支撑体的运动进行限位。
如图13所示，各磁石背板13均各具有至少一个连通侧向磁石60和周向侧壁112的点胶缝133。通过这样设置，可以有效地保证侧向磁石60与磁石背板13连接的稳定性。

需要指出的是，其中一个位置传感器200是霍尔芯片，每个霍尔芯片上具有多个霍尔元件，与每个霍尔芯片连接的引脚25分别控制霍尔芯片上VCC接入电路的电压供电电压、VDD器件内部的工作电压即芯片的工作电压、SDA串行数据线以及SCL时钟数据线。并且，每个霍尔元件分别与一组串联的侧向线圈70连接，从而对透镜支撑体30在垂直于侧向线圈70方向上的抖动造成的位置偏差进行补正。
