Description

镜头模组
【技术领域】
本实用新型涉及镜头光学成像技术领域，尤其涉及一种镜头模组。
【背景技术】
近年来，智能手机、平板电脑以及相机等电子产品上都安装有高性能镜头模组。在拍照时，如果镜头模组发生抖动会导致拍摄出来的照片模糊，为了保证拍摄图像的质量，镜头模组通常都会具有防抖功能。
现有的防抖方案，通常将驱动线圈和磁钢安装在镜头的侧面，通过侧向推力来调整镜头的位置，以实现镜头模组的防抖功能。但电磁驱动的方式响应相对较慢，而且侧面安装电磁推动装置，需要在底部设置支点结构才能方便的调整摄像头的角度，从而影响用户的操作体验和镜头模组的产品性能，不满足镜头模组快速响应的特点。
因此，有必要提供一种改进的镜头模组来解决上述问题。
【实用新型内容】
本实用新型的目的在于提供一种镜头模组，其具有响应迅速，不需要底部支点结构即可方便和全方位的调整摄像头位置的优点。
本实用新型的目的采用如下技术方案实现：
一种镜头模组，包括具有收容腔的外壳、悬置于所述收容腔内的镜头、环设固定于所述镜头的第一固定块、与所述第一固定块间隔设置且固定于所述外壳的第二固定块、以及设置于所述第一固定块与所述第二固定块之间的压电驱动装置，所述压电驱动装置环设于所述镜头的四周以驱动所述镜头作偏摆运动。
作为一种改进，所述压电驱动装置的延伸方向垂直于所述镜头的光轴。
作为一种改进，所述第一固定块、所述压电驱动装置及所述第二固定块沿所述镜头的光轴方向间隔平行分布。
作为一种改进，所述镜头模组还包括从所述第一固定块上延伸出来并固定于所述压电驱动装置一个表面的第三固定块及从所述第二固定块上延伸出来并固定于所述压电驱动装置另一个表面的第四固定块。
作为一种改进，所述第三固定块固定于所述压电驱动装置的一端，所述第四固定块固定于所述压电驱动装置的另一端。
作为一种改进，所述压电驱动装置包括层叠设置的第一压电片和第二压电片，所述第三固定块固定于所述第二压电片朝向所述第一固定块的一侧，所述第四固定块固定于所述第一压电片朝向所述第二固定块的一侧。
作为一种改进，所述第三固定块与所述第一固定块为一体成型或者分体组装成型；且/或，
所述第四固定块与所述第二固定块为一体成型或者分体组装成型。
作为一种改进，所述压电驱动装置设有多个，多个所述压电驱动装置沿所述镜头的周向均匀间隔分布。
作为一种改进，所述外壳包括侧板及分别连接于所述侧板相对两侧的第一盖板和第二盖板，所述第一盖板、所述侧板及所述第二盖板围合形成所述收容腔，所述第一盖板贯穿设有与所述收容腔连通且与所述镜头正对的通光孔，所述压电驱动装置位于所述镜头与所述侧板之间。
作为一种改进，所述镜头模组还包括连接于所述镜头与所述收容腔内壁之间的弹性支撑件，所述弹性支撑件包括环设固定于所述镜头的内框、环设于所述内框外并与所述内框相间隔的外框、以及连接于所述内框与所述外框之间的柔性连接梁，所述外框与所述外壳固定连接。
作为一种改进，所述柔性连接梁的一端与所述外框连接、另一端沿弧形轨迹延伸至所述内框。
本实用新型实施方式相对于现有技术而言，通过设置与镜头固定连接的第一固定块和与外壳固定连接的第二固定块，第一固定块和第二固定块之间连接有压电驱动装置，当压电驱动装置通入不同极性的电压时，压电驱动装置就会产生形变，进而驱动镜头进行偏摆运动，以此来补偿镜头因抖动而产生的位移，实现镜头模组的防抖功能，以保证拍摄质量。由于设置有可以实现镜头模组防抖功能的压电驱动装置，因此不需要再额外设置支点结构，即可方便的、全方位的调整镜头的位置，而且压电驱动装置响应非常迅速，大大提升了用户的操作体验，同时压电驱动装置可以做的很薄，因此其占用空间小，有助于实现镜头模组的小型化。

【具体实施方式】
下面结合附图和实施方式对本实用新型作进一步说明。
需要说明的是，本实用新型实施例中所有方向性指示（诸如上、下、左、右、前、后、内、外、顶部、底部……）仅用于解释在某一特定姿态（如附图所示）下各部件之间的相对位置关系等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。

请参阅图1-图5，本实用新型实施例提供的一种镜头模组100，适用于电子设备，该镜头模组100包括外壳10、镜头20、第一固定块30、第二固定块40以及压电驱动装置50，外壳10设有收容腔11，镜头20、第一固定块30、第二固定块40以及压电驱动装置50都设置在收容腔11内，镜头20悬置在收容腔11内并可相对外壳10运动，第一固定块30与第二固定块40沿镜头20的光轴方向间隔相对设置，且第一固定块30环设固定于镜头20的外周，第二固定块40固定于外壳10的内壁，压电驱动装置50位于第一固定块30与第二固定块40之间并环设于镜头20的四周，且压电驱动装置50通过第一固定块30与镜头20连接、通过第二固定块40与外壳10连接，压电驱动装置50用于驱动镜头20做偏摆运动。
压电驱动装置50包括沿镜头20的光轴方向层叠设置的第一压电片51和第二压电片52，第一压电片51与第二固定块40连接，第二压电片52与第一固定块30连接。可以理解地，压电驱动装置50的设置方式并不局限于以上所述，例如，在第一压电片51和第二压电片52之间额外设置一可以形变的支撑件也是可以的。
压电驱动装置50具有压电效应，也即，当往第一压电片51和第二压电片52通入不同方向的电压时，第一压电片51和第二压电片52就会产生形变，具体地，第一压电片51和第二压电片52中的一个进行伸长，另一个则进行收缩，使得压电驱动装置50整体上凸或者下凹（即使压电驱动装置50呈拱形），且压电驱动装置50上凸或者下凹程度与通入电压的大小有关，并带动镜头20进行偏摆，以补偿镜头20因抖动而产生的位移，实现了镜头模组100的防抖功能，保障了拍摄质量，由于设置有压电驱动装置50就可以实现防抖功能，因此不需要额外设置支点结构，即可方便的、全方位的调整镜头20的位置，而且第一压电片51和第二压电片52响应非常迅速，可以在很短的时间内产生形变以实现防抖功能，大大提升了用户的操作体验，同时第一压电片51和第二压电片52可以制作的很薄，因此其占用的空间较小，有助于实现镜头模组100的小型化。
电子设备的类型不做限定，例如，电子设备可以是手机或者平板电脑等智能终端，也可以是相机等包括镜头的数码设备。
外壳10和镜头20的形状不做限定，例如，可以是圆筒形，也可以是方形。
优选地，压电驱动装置50的延伸方向与镜头20的光轴垂直，也即，第一压电片51和第二压电片52的延伸方向与镜头20的光轴垂直，因此，当第一压电片51和第二压电片52通入不同方向的电压时，二者就会在与光轴垂直的平面内进行伸长或收缩。
作为本实施例的一种改进方式，外壳10包括侧板12和分别连接于侧板12相对两侧的第一盖板13与第二盖板14，第一盖板13、侧板12以及第二盖板14围合形成收容腔11，第一盖板13贯穿设有与收容腔11连通的通光孔131，该通光孔131与镜头20正对设置。
优选地，侧板12为由四个板体围合而形成的方形框体，第一盖板13和第二盖板14垂直连接在侧板12的两侧，使外壳10整体呈方形，通光孔131沿光轴的方向贯穿第一盖板13，光线可以通过通光孔131进入镜头20。
可以理解地，第一盖板13不是必要的，即不设置第一盖板13也是可以的；而且通光孔131也不是必须的，例如，当第一盖板13是透明板体时，光线也可以通过第一盖板13进入镜头20，透明的第一盖板13整体即为通光孔131，只要能使光线能进入镜头20即可。
本实施例中，镜头模组100还包括柔性电路板60，柔性电路板60的一端穿过侧板12后与镜头20电性连接。
作为本实施例的一种改进方式，镜头模组100还包括从第一固定块30上延伸出来并固定于压电驱动装置50一个表面的第三固定块70和从第二固定块40上延伸出来并固定于压电驱动装置50另一个表面的第四固定块80。
本实施例中，第三固定块70固定于第二压电片52朝向第一固定块30的一侧，第四固定块80固定于第一压电片51朝向第二固定块40的一侧，第三固定块70垂直连接在第二压电片52的一端与第一固定块30之间，第四固定块80垂直连接在第一压电片51远离第三固定块70的一端与第二固定块40之间，也即，压电驱动装置50、第一固定块30及第二固定块40沿镜头20的光轴方向间隔平行分布，使压电驱动装置50与第一固定块30和第二固定块40之间都存在间距，以给压电驱动装置50上凸或者下凹留出空间。可以理解地，第三固定块70不一定要与第二压电片52垂直连接，第四固定块80也不一定要与第一压电片51垂直连接，例如，第三固定块70、第四固定块80、第一压电片51以及第二压电片52装配在一起呈Z字形也是可以的。
优选地，第一固定块30固定连接于镜头20，第二固定块40固定于侧板12的内侧且位于第一固定块30的正下方，也即间隔设于第一固定块30远离第一盖板13的一侧，压电驱动装置50位于镜头20与侧板12之间。可以理解地，第一固定块30和第二固定块40的设置方式并不局限于以上所述，例如，使第二固定块40与镜头20固定连接，第一固定块30与侧板12固定连接，然后使镜头20的一端可活动地穿过第一固定块30也是可以的。
优选地，第三固定块70与第一固定块30为一体成型，第四固定块80与第二固定块40为一体成型。保证了第一固定块30与第三固定块70以及第二固定块40与第四固定块80的整体强度。可以理解的是，第一固定块30与第三固定块70以及第二固定块40和第四固定块80为分体组装成型也是可以的。
作为本实施例的一种改进方式，压电驱动装置50设有多个，多个压电驱动装置50沿镜头20的周向均匀间隔分布，也即，任意相邻两个压电驱动装置50的中心之间的距离都相同，当往多个压电驱动装置50通入大小不同的电压时，各个压电驱动装置50产生的形变量也就不同，镜头20就会从形变量大的一侧朝向形变量小的一侧倾斜（或者从上凸的一侧朝向下凹的一侧倾斜），使镜头20进行偏摆运动，而且由于压电驱动装置设有多个，多个驱动装置50相互配合共同控制镜头20进行偏摆，以全方位的调整镜头20的位置，提升了镜头模组100的防抖效果。具体地，压电驱动装置50设有三个，三个压电驱动装置50的中心连线为一等边三角形，且每个压电驱动装置50的一端都固定连接有一个第三固定块70，另一端都固定连接有一个第四固定块80，三个压电驱动装置50共同控制镜头20运动。可以理解的是，相邻两个压电驱动装置50之间的距离不相同也是可以的。
作为本实施例的一种改进方式，镜头模组100还包括弹性支撑件90，弹性支撑件90位于第一盖板13与第一固定块30之间，且弹性支撑件90可以起到支撑镜头20的作用，从而将镜头20悬置在收容腔11内，该弹性支撑件90包括内框91、外框92以及柔性连接梁93，内框91和外框92都呈环形，内框91环设在镜头20外并与镜头20固定连接，外框92环设在内框91并与内框91相互间隔，外框92固定于侧板12的内壁，柔性连接梁93位于内框91与外框92之间，且柔性连接梁93的一端与外框92固定连接、另一端沿弧形轨迹延伸至内框91。
本实施例中，当压电驱动装置50驱动镜头20运动时，由于内框91是与镜头20固定连接的，因此，内框91会跟随镜头20一起运动，使得柔性连接梁93发生形变，柔性连接梁93优选为由柔性材料制成，且柔性连接梁93沿弧形轨迹从外框92延伸至内框91，增加了柔性连接梁93的长度，从而降低了柔性连接梁93的刚度，有效地避免了由于柔性连接梁93刚度过大而影响镜头20运动的问题。
优选地，柔性连接梁93设有三个，且三个柔性连接梁93均匀间隔设置在内框91与外框92之间，也即，内框91和外框92上均布有三个连接点，柔性连接梁93的一端与内框91上的连接点连接，另一端沿弧形轨迹延伸至外框92上相应的一个连接点，使得三个柔性连接梁93错位设置，因此三个柔性连接梁93的长度互不影响。可以理解的是，柔性连接梁93的数量并不局限于三个，例如一个、两个或者其它数量的多个也是可以的，而且柔性连接梁93也不一定要呈弧形延伸，例如，柔性连接梁93从内框91垂直或者倾斜延伸至外框92也是可以的。
以上所述的仅是本实用新型的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本实用新型创造构思的前提下，还可以做出改进，但这些均属于本实用新型的保护范围。
