Definitions

  • This application relates to the field of camera modules, and more specifically, to light-converting modules and their assembly methods, reflection modules, reflection systems, camera modules, and periscope camera modules.
  • Camera modules are an essential component of mobile electronic devices. With the further development of camera module technology, user demands for them are becoming increasingly sophisticated. The development of camera products not only needs to meet high-performance requirements such as background blur, night shooting, and dual-camera zoom, but also needs to meet the requirements of miniaturization, portability, and compactness. In particular, periscope camera modules, through their optical path bends, achieve a longer focal length by folding the optical path, thus simultaneously meeting the demands for high zoom and a slim design, and have broad market prospects.

Since the prism or mirror itself does not have optical power, its rotation only changes the direction of light propagation and does not affect the convergence state of the light. Therefore, when the prism or mirror is driven to rotate around the first direction X or around the second direction Y, the propagation of the light will not be distorted, thus keeping the value of the modulation transfer function (MTF) stable.

  • This asymmetrical light distribution disrupts the uniform reception of light rays from different fields of view by the lens module 77101.
  • the light deflection in the edge fields of view is further amplified, ultimately leading to a significant attenuation of the modulation transfer function (MTF) value.
  • MTF modulation transfer function
  • the rotation of the reflective element 7711 and the second lens 7713 around the second direction Y is equivalent to rotation within a plane parallel to the photosensitive chip. Only the image plane angle rotates; there is no shift in the image plane height. Due to the inherent symmetry of the second lens 7713's structure, its beam-expanding effect on light remains symmetrical in the horizontal direction. When edge rays from both sides of the central field of view pass through the rotated second lens 7713, their exit angle and propagation direction are not additionally disturbed, maintaining a near-original optical path symmetry.

Specifically, if only the reflective element 13 is driven to rotate around the first axis A1 and/or around the second axis A2, while the first lens 11 and the second lens 12 remain fixed, then the first lens 11 and the second lens 12 need to be fixed by the fixing assembly 60, so that the first lens 11 is located on the light-incident side of the reflective element 13 and the second lens 12 is located on the light-outceasing side of the reflective element 13.

  • the first lens 11 and the second lens 12 are mounted on the movable carrier 20. Since the size of the movable carrier 20 is smaller than that of the fixed assembly 60, the first lens 11 and the second lens 12 do not need to have large dimensions for mounting and fixing, which helps to reduce the size and weight of the first lens 11 and the second lens 12. In addition, the gap between the first lens 11, the reflecting element 13, and the second lens 12 can be smaller, which helps to make the structure of the reflecting system 1 more compact, thereby reducing the size of the camera module 2 along the first axis A1 and along the third axis A3.

  • the second optical axis OA2 is parallel to the third axis A3.
  • the first lens 11 has positive optical power, which allows it to focus light rays. This means that light rays along the first optical axis OA1 are focused after passing through the first lens 11, thus increasing the amount of light entering the camera module 2 without changing its physical aperture. In other words, it is equivalent to increasing the effective aperture of the camera module 2. It should be understood that compared to a lens without positive optical power, the first lens 11 with positive optical power in this embodiment can capture more light under the same lighting conditions, thereby improving the imaging quality of the camera module 2. It is worth mentioning that increasing the amount of light entering the camera is particularly important for improving the imaging quality of the camera module 2 in low-light environments.
  • the light rays converged by the first lens 11 remain converged after being reflected by the reflecting element 13, thus requiring a smaller size for the second lens 12.
  • the dimensions of each optical lens in the lens module 101 along the direction parallel to the first axis A1 are quite close to the dimensions of the second lens 12 along the same direction. Therefore, under the condition that the light rays are converged by the first lens 11, it also helps to reduce the effective optical diameter of each optical lens in the lens module 101 of the camera module 2 along the direction parallel to the first axis A1, thereby reducing the shoulder height h of the camera module 2. This facilitates the miniaturization of the camera module 2 and caters to the trend of thinner and lighter electronic devices.
  • the light incident onto the reflective element 13 is converged by the first lens 11, so that the reflection point of the converged light at the outermost edge of the reflective element 13 is closer to the first optical axis OA1.

  • the object side and image side of the first lens 11 are both convex, which allows light to be refracted twice when it passes through the first lens 11. This is beneficial to enhance the light-gathering effect of the first lens 11, and to further reduce the distance between the first lens 11 and the reflecting element 13, making the structure of the reflecting system 1 more compact and facilitating the miniaturization of the camera module 2.
  • the second lens 12 has negative optical power, which expands the light beam, so that the light along the second optical axis OA2 is expanded after passing through the second lens 12. It should be understood that if there is no second lens 12 or the second lens 12 does not have the function of expanding the beam, the light beam that is converged by the first lens 11 will still be in a converged state after being reflected by the reflective element 13 and will propagate to the various optical lenses of the lens module 101. That is to say, the light beam before reaching the lens module 101 is still in a converged state, which results in a small coverage area of the light beam reaching the lens module 101.
  • the reflective element 13 moves during optical image stabilization, for example, rotating around the first axis A1 and/or around the second axis A2, the light beam is relatively concentrated. Even a small stroke of the reflective element 13 can easily cause a large change in the relative position of the light beam on the lens module 101, resulting in a large drop in the MTF (Modulation Transfer Function) of the camera module 2, and ultimately a decrease in the sharpness of the image. Furthermore, both camera modules are overly sensitive to shaking, which reduces image stability and causes more severe image shakiness during shooting.
  • MTF Modulation Transfer Function
  • the light rays converged by the first lens 11 are diffused after passing through the second lens 12, increasing the coverage area of the light reaching the lens module 101.
  • the increased light coverage area means that the movement of the reflective element 13 has a relatively small impact on the position of the light rays on the lens module 101.
  • the light rays are diffused by the second lens 12 before reaching the lens module 101, preventing the light rays from concentrating on a very small area. Consequently, when the reflective element 13 is driven for optical image stabilization, the MTF drop value of the camera module 2 is smaller, resulting in better image clarity.
  • the camera module 2 has a more moderate response to shaking, which helps improve image stability and makes the image more stable during shooting. That is, the difference between the MTF design value per unit shaking angle and the static MTF design value of the camera module 2 is smaller, allowing the camera module 2 to obtain clearer images in motion or vibration scenarios.

That is, during optical image stabilization, the first lens 11, the reflective element 13, and the second lens 12 are all fixed to the movable carrier 20, so that the relative position and relative angle between the first lens 11, the reflective element 13, and the second lens 12 are stable.
  • the propagation path and propagation angle of the light can be kept stable during the process of light passing through the first lens 11 and entering the reflective element 13, and then being reflected by the reflective element 13 to the second lens 12. This not only improves the clarity of the image, but also enhances the overall image quality.
  • the moving carrier 20 only supports the rotation of the reflective element 13 around the first axis A1 and/or around the second axis A2, while the first lens 11 and the second lens 12 remain fixed, the relative position and angle between the reflective element 13 and the first lens 11 and the second lens 12 will change. Consequently, the propagation path and angle of light between the first lens 11 and the reflective element 13, as well as between the reflective element 13 and the second lens 12, will also change. This may result in light having a propagation path and angle beyond the image stabilization requirements after passing through the convergence, reflection, and expansion of the reflective assembly 10, thus adversely affecting the performance of the entire camera module 2.
  • the focusing position of light when it exits the lens module 101 and reaches the imaging module 105 also changes, which may cause the imaging focus to deviate from the optimal imaging plane, resulting in problems such as blurring, distortion, or astigmatism in the final image of the camera module 2, affecting the imaging quality of the camera module 2.
  • the movable carrier 20 is adapted to carry and drive the first lens 11, the reflective element 13 and the second lens 12 to rotate synchronously around the first axis A1 and/or synchronously around the second axis A2, so that the propagation path and angle of light between the first lens 11 and the reflective element 13, as well as the propagation path and angle of light between the reflective element 13 and the second lens 12, are stable.
  • This helps to reduce the movement of the light focusing position when the light passes through the lens module 101 and is emitted to the imaging module 105, so that the imaging focus approaches the optimal imaging plane, thereby reducing imaging defects such as blurring, distortion or astigmatism caused by changes in the propagation path and propagation angle of light, and thus improving the imaging quality of the camera module 2.
  • the scheme in this application that allows the first lens 11, the reflective element 13 and the second lens 12 to move synchronously optimizes the overall performance and reliability of the reflection system 1, which is beneficial to improving the overall quality of the final image of the camera module 2 and to achieving high-quality image output in low light environments and in motion or vibration scenarios.

  • the reflective element 13 is driven to rotate around the first axis A1 and/or around the second axis A2, while the first lens 11 and the second lens 12 remain fixed, the light may, after passing through the convergence, reflection, and expansion of the reflective assembly 10, produce propagation paths and angles beyond the requirements of image stabilization, adversely affecting the performance of the entire camera module 2. Therefore, when designing the reflective system 1, it is necessary to further consider how to compensate for or eliminate the adverse effects caused by changes in the propagation path and angle of the light.
  • the movable carrier 20 drives the reflective assembly 10 to move synchronously, ensuring that the propagation path and angle of light between the first lens 11 and the reflective element 13, as well as between the reflective element 13 and the second lens 12, remain unchanged.

与现有技术相比，本发明的有益效果在于：
当旋转框架被驱动绕第一旋转轴转动时，旋转框架的旋转方向被旋转引导轴限制为仅能够实现绕第一旋转轴进行转动，而不会存在摇摆运动的干扰，以提高反射模块的转动精度。
活动组件得以承载反射元件并带动反射元件绕第二方向旋转，使得成像模块的成像面上的图像产生绕第二方向旋转的效果，进而得以补偿摄像模组在使用过程中的旋转抖动和倾斜抖动，起到减少相差，提高成像质量的效果。
第一透镜具有正光焦度，得以对光线进行收束，在不改变摄像模组的物理光阑孔径的基础上起到增加进光量的作用。并且，经过第一透镜收束的光线在被反射元件反射后仍保持收束的状态，因而所需的第二透镜的尺寸也较小，有利于减小第二透镜沿平行于第一轴A1方向的尺寸，也有利于减小摄像模组的镜头模块中的各个光学透镜沿平行于第一轴A1方向的光学有效径，进而得以降低摄像模组的总高和肩高，有利于实现摄像模组的小型化，得以迎合电子设备轻薄化的发展趋势。
第一透镜、反射元件和第二透镜被设置于活动载体，并通过第一驱动组件和第二驱动组件驱动第一透镜、反射元件和第二透镜一起旋转运动，以减小光线传播路径和传播角度变化而引起的像糊、畸变或像散等成像缺陷。
第一透镜、反射元件和第二透镜均被固定于活动载体，使得反射镜与第一透镜和第二透镜的相对位置和相对角度稳定，当第一透镜、反射元件和第二透镜被驱动一起旋转运动时，可以保持光线的传播路径和传播角度的稳定性，不仅提高了成像的清晰度，还增强了图像的整体质量。

申请概述
潜望式摄像模组主要通过转折光路的方案来实现长焦距拍摄。潜望式摄像模组通过光路的弯折来增大模组的焦距，而其高度尺寸却与直线式模组相近，因此，能满足终端设备的尺寸要求。
具体地，潜望式摄像模组在镜头组件的物侧设置有棱镜，其中，棱镜将入射到摄像模组物侧的光线进行反射，以改变光线的方向，使得被转折的光线通过镜头组件和滤色片后到达感光芯片，进而使得摄像模组能够以横放的方式安装于电子设备中，以保障潜望式摄像模组在满足长焦距拍摄效果的同时降低潜望式摄像模组的高度。
因此，潜望式摄像模组能够通过转变入射光线的角度，合理改变较长的镜头结构，降低模组高度，在很大程度上实现终端设备小型化以及光学变焦的要求。这里，“摄像模组以横放的方式安装于电子设备中”是指：摄像模组以其镜头组件和感光芯片的光轴与电子设备(例如，手机)的厚度方向偏离，例如，呈90度角，的方式安装于电子设备中。
目前的潜望式摄像模组依旧不能很好地满足市场的要求。应可以理解，在潜望式摄像模组的光学系统中，光圈会直接影响潜望式摄像模组的夜景、抓拍、背景虚化、视频等功能，而且使用大光圈(光圈F值更小)镜头拍摄时可以增加照片的虚化背景并突显主体，还可以提高快门速度和对焦速度，并获得较好的成像质量。
然而，对潜望式摄像模组的大光圈需求与终端设备的小型化和轻薄化发展趋势以及驱动力需求相矛盾。其中，由于棱镜的入光面和出光面尺寸的限制，导致棱镜接收光线的面积受限，进而导致镜头的进光量少，有效光圈小，从而带来了暗光效果差/虚化效果不佳等问题。
随着潜望式摄像模组的光圈变大，棱镜的尺寸也需要随之增大，这使得棱镜的重量也会更大，进而使得潜望式摄像模组的尺寸和重量增加。而且，当通过马达驱动棱镜移动以实现潜望式摄像模组的光学防抖功能时，更大尺寸和更大重量的棱镜对马达的推力提出了更高的要求。由于棱镜的尺寸和重量增大，使得棱镜在潜望式摄像模组中所占用的空间更多，进而造成马达能够利用的空间更少，影响驱动效果。增大驱动力和减小安装空间的双重要求无疑对马达提出了更高的要求。
在本申请的一个实施例中，在反射元件的入光侧设置具有非平面面型的光矫正元件，以调整射向反射元件的光线的方向，实现光线收束，并通过对光线的收束增加进光量，使得潜望式摄像模组在不增加模组高度尺寸的情况下增大有效光圈；在反射元件的出光侧也设置具有非平面面型的光矫正元件，以调整反射元件反射的光线，实现光线扩束，使得反射元件反射的光线按照预设的方式出射至镜头模块。
进一步地，设置在反射元件的入光侧的光矫正元件可以通过一体成型的方式或者成型后贴附的方式设置于反射元件。然而，应可以理解，当光矫正元件紧贴于反射元件(例如，棱镜)时，光矫正元件的与棱镜相贴的面为平面，没有与反射元件相紧贴的面能够形成光矫正面；相应地，光矫正元件仅能够对光线进行单次矫正，可能使得矫正的效果不明显。
相应地，本申请进一步提出：光矫正元件在设置时与反射元件相间隔，使得光矫正元件的朝向反射元件的面也能够有选择地设置非平面面型，增加光矫正元件对光线的矫正次数，提高矫正效果。
进一步地，当反射元件被实施为棱镜时，在棱镜的入光侧的表面和出光侧的表面分别设置有光矫正元件，这会进一步增加反射元件的尺寸和重量，进而导致潜望式摄像模组的尺寸和重量增加。
基于此，本申请提出了一种光转折模块，其包括：反射元件、第一透镜，以及，第二透镜。所述第一透镜位于所述反射元件的入光侧，且与所述反射元件相间隔；所述第一透镜的至少一个侧面具有非平面面型。所述第二透镜位于所述反射元件的出光侧，且与所述反射元件相间隔。所述第二透镜的至少一个侧面具有非平面面型。所述第一透镜被用作位于反射元件的入光侧的光矫正元件；所述第二透镜被用作位于反射元件的出光侧的光矫正元件；能够增大镜头模块的进光量，使得所述潜望式摄像模组在不增加模组高度的情况下，实现大光圈，提升镜头的成像效果。且所述第一透镜与所述反射元件之间的间隔，以及，所述第二透镜与所述反射元件之间的间隔为所述第一透镜的朝向所述反射元件的面型设计和所述第二透镜的朝向所述反射元件的面型设计提供了可选择性，提高了所述第一透镜的朝向所述反射元件的面型设计和所述第二透镜的朝向所述反射元件的面型的设计灵活性。
在介绍本申请的基本原理之后，下面将参考附图来具体介绍本申请的各种非限制性实施例。
名词解释
为方便理解，下面先对本申请所涉及的技术术语进行解释和描述。
1.镜头：是利用透镜的折射原理，使景物光线通过后在聚焦平面上形成清晰的影像的部件。
2.光轴：为光学系统传导光线的方向，参考中心视场的主光线。对于对称透射系统，一般与光学系统旋转中心线重合。对于离轴和反射系统，光轴也会呈现为折线。
3.物侧、像侧：以透镜为界，被摄物体所在的一侧为物侧，透镜靠近物侧的表面可以称为物侧面；以透镜为界，被摄物体的图像所在的一侧为像侧，透镜靠近像侧的表面可以称为像侧面。
4.焦距(focal length)：也称为焦长，是光学系统中衡量光的聚集或发散的度量方式，指无限远的景物通过透镜或透镜组在焦平面结成清晰影像时，透镜或透镜组的光学中心至焦点的距离，也可以理解为透镜或透镜组的光学中心至焦平面的垂直距离。从实用的角度可以理解为镜头中心至成像平面的距离。
5.光阑(diaphragm)：指用来限制成像光束大小或成像空间单位的光学组件中光学元件的边缘、框架或特别设置的带孔屏障。
6.光圈(aperture)：是用来控制光线透过镜头，进入机身内感光面光量的装置，它通常是在镜头内。表达光圈大小用F/数值表示。
7.光圈F值：等于镜头焦距除以入瞳直径。在镜头焦距不变的情况下，入瞳直径越大，则光圈越大，光圈F值越小，进光量越多，画面比较亮，主体背景虚化越大；相反，入瞳直径越小，则光圈越小，光圈F值越大，进光量越少，画面比较暗，主体前后越清晰。
8.光学总长(total track length，TTL)：指从镜筒头部至成像面的总长度，是形成相机高度的主要因素。
9.感度：单位抖动角度下MTF设计值与静态下MTF设计值之间的差值。
10.MTF(Modulation Transfer Function)：调制传递函数，描述光学系统成像质量的重要指标。
为了便于描述，界定反射模块8810和潜望摄像模组沿相互垂直的第一光轴OA1、第二光轴OA2和第 三轴OA3延伸分布。其中，沿第三轴OA3延伸界定潜望摄像模组的宽度，沿第二光轴OA2延伸界定潜望 摄像模组的长度，沿第一光轴OA1延伸界定潜望摄像模组的高度(厚度)。

为了便于描述，界定所述潜望式摄像模组991沿相互垂直的第一轴Z1、第二轴Y1和第三轴X1延伸分布。所述潜望式摄像模组991沿所述第三轴X1延伸界定所述潜望式摄像模组991的宽度，沿所述第二轴Y1延伸界定所述潜望式摄像模组991的长度，沿所述第一轴Z1延伸界定所述潜望式摄像模组991的高度(厚度)。所述第一方向D1平行于所述第一轴Z1；所述第二方向D2平行于所述第二轴Y1；界定平行于所述第三轴X1的方向为第三方向D3。相应地，所述第一方向D1垂直于所述第二方向D2。
所述光转折模块9910、所述镜头模块9920和所述感光模块9930沿所述第二轴Y1被装配于所述基座9950。所述基座9950包括第一空间99501、第二空间99502和第三空间99503。所述第一空间99501、所述第二空间99502和所述第三空间99503沿所述第二轴Y1依次排布。所述第一空间99501、所述第二空间99502和所述第三空间99503可以由相互独立的构件组合而成，也可以由一体式的构件形成，本申请对此不作限制。所述第一空间99501适于收容所述光转折模块9910；所述第二空间99502适于收容所述镜头模块9920。相应地，所述光转折模块9910被安装于所述第一空间99501；所述镜头模块9920被安装于所述第二空间99502；所述感光模块9930被安装于所述第三空间99503。
在本申请的一个实施例中，所述基座9950可以为一体式结构也可以为分体式结构。例如，所述基座9950为一体式结构，所述光转折模块9910和所述镜头模块9920安装于所述基座9950；例如，所述基座9950为分体式结构，所述基座9950包括第一基座9951和第二基座9952，所述光转折模块9910安装于所述第一基座9951，所述镜头模块9920安装于所述第二基座9952。
所述光转折模块9910包括：反射元件9911、第一透镜9912，以及，第二透镜9913。所述第一透镜9912位于所述反射元件9911的入光侧，且与所述反射元件9911相间隔；所述第一透镜9912的至少一个侧面具有非平面面型。所述第二透镜9913位于所述反射元件9911的出光侧，且与所述反射元件9911相间隔。所述第二透镜9913的至少一个侧面具有非平面面型。所述反射元件9911被配置为将沿所述第一方向D1入射的光线R转折为沿所述第二方向D2出射的光线R。所述第一透镜9912被用作位于所述反射元件9911的入光侧的光矫正元件；所述第二透镜9913被用作位于所述反射元件9911的出光侧的光矫正元件。所述光转折模块9910能够增大所述镜头模块9920的进光量，使得所述潜望式摄像模组991在高度尺寸不变的情况下，实现大光圈，提升所述潜望式摄像模组991的成像效果。
所述第一透镜9912与所述反射元件9911之间的间隔，以及，所述第二透镜9913与所述反射元件9911之间的间隔为所述第一透镜9912的朝向所述反射元件9911的面型设计和所述第二透镜9913的朝向所述反射元件9911的面型设计提供了可选择性，提高了所述第一透镜9912的朝向所述反射元件9911的面型设计和所述第二透镜9913的朝向所述反射元件9911的面型的设计灵活性。
应可以理解，本申请中所述第一透镜9912与所述反射元件9911相间隔是指所述第一透镜9912与所述反射元件9911的至少一部分之间具有一定间隙，而并非所述第一透镜9912与所述反射元件9911之间完全不接触；所述第二透镜9913与所述反射元件9911相间隔是指所述第二透镜9913与所述反射元件9911的至少一部分之间具有一定间隙，而并非所述第二透镜9913与所述反射元件9911之间完全不接触。
具体地，所述第一透镜9912被配置为收束光线R；所述第二透镜9913被配置为扩束光线R，使得光线R沿所述第一方向D1入射至所述第一透镜9912并经所述第一透镜9912收束后从所述第一透镜9912射出，到达所述反射元件9911，进而经由所述反射元件9911反射后沿所述第二方向D2射出，到达所述第二透镜9913并经所述第二透镜9913扩束后射出。
本申请考虑到如果所述第一透镜9912或所述第二透镜9913仅能够对光线R进行单次矫正，可能使得矫正的效果不明显，本申请提出：可将所述第一透镜9912的入光面和出光面都设计为非平面，将所述第二透镜9913的入光面和出光面都设计为非平面，使得所述潜望式摄像模组991在所述反射元件9911的入光侧或者出光侧对光线R多次光矫正，能够在一定程度上提高矫正效果。由此可见，所述反射元件9911和所述光矫正元件的配置结构和布设方式允许单个光矫正元件在所述反射元件9911的入光侧和/或出光侧能够对光线R进行多次矫正。
相应地，所述第一透镜9912具有第一透镜一侧面99121和第一透镜二侧面99122，其中，所述第一透镜一侧面99121背离所述反射元件9911，所述第一透镜二侧面99122朝向所述反射元件9911；所述第一透镜一侧面99121被配置为对光线R进行收束；所述第一透镜二侧面99122被配置为对光线R进行再次收束。所述第一透镜9912具有正光焦度，能够通过对光线R进行多次收束，能够使得更大范围的光线R进入所述第一透镜9912中，以增加进光量，进而实现大光圈，这意味着在相同的光线R条件下，可以捕获更多的光线R，从而提高成像的亮度。而且，在低光环境下，增大光圈可以捕获更多的光线R，这对于提升所述潜望式摄像模组991在暗光条件下的成像质量尤为重要。
在本申请的一个实施例中，在所述第一透镜9912的入光侧设置光阑，这样，光阑的大小不会被所述潜望式摄像模组991的高度尺寸所限制，这使得增加光阑的孔径以提升所述潜望式摄像模组991的进光量时不会导致所述潜望式摄像模组991的高度尺寸增加。也就是，在不增加所述潜望式摄像模组991的高度尺寸的情况下增大有效光圈。在本实施例中，光圈即光阑，它限制了整个光学系统的进光量。
具体地，所述第一透镜一侧面99121具有凸面的面型，所述第一透镜二侧面99122具有凸面的面型；也就是，所述第一透镜9912为双面凸出的透镜。
进一步地，本申请的双面凸出的所述第一透镜9912能有效地将光线R汇聚于一点。单面凸出的透镜同样具有正光焦度，但相比双面凸出的所述第一透镜9912，其焦距可能会更长，即对光线R的收束作用相对较弱。而且，双面凸出的所述第一透镜9912因为所述第一透镜一侧面99121和所述第一透镜二侧面99122都具有凸面面型，可以对光线R进行两次折射，通常能更有效地收束光线R，以使得更大范围的光线R进入所述潜望式摄像模组991内。而单面凸出的透镜由于一个面是平面，对光线R的折射作用只有一次，其收束效果可能不如双面凸出的所述第一透镜9912强烈。
所述第二透镜9913具有第二透镜一侧面99131和第二透镜二侧面99132，其中，所述第二透镜一侧面99131朝向所述反射元件9911，所述第二透镜二侧面99132背离所述反射元件9911；所述第二透镜一侧面99131被配置为对光线R进行扩束；所述第二透镜二侧面99132被配置为对光线R进行再次扩束。所述第二透镜9913具有负光焦度，能够通过将由所述反射元件9911出射的光线R进行扩束，控制出射的光线R以趋近于平行所述第二方向D2的角度进入所述镜头模块9920。应可以理解，在本申请中所述的趋近于平行，即两条直线近似平行或完全平行，也就是，两条直线间存在0°-5°的夹角的情况也被称为平行。
具体地，所述第二透镜一侧面99131具有凹面的面型，所述第二透镜二侧面99132具有凹面的面型。
应可以理解，若不设置所述第二透镜9913，则光线R经过所述第一透镜9912的收束后到达所述反射元件9911，并在所述反射元件9911处被反射后直接到达所述镜头模块9920，这样，到达所述镜头模块9920的光线R仍然处于收束状态，如图3所示；在这样的情况下，如果所述反射元件9911在进行光学防抖操作时发生移动，边缘各个方向光线R的偏转角度是不同的。具体地，因为所有光线R都是中心方向汇聚，但是防抖时所有光线R会朝向同一方向偏移，从而导致边缘各个方向光线R经过所述反射元件9911之后偏转角度不同，光学系统的MTF的掉落值较大，即，OIS感度较高。这里，MTF可以通过光学系统仿真得出，MTF的掉落值即单位抖动角度下MTF与静态MTF设计值的差值，也可以被称为光学防抖(Optical Image StabiliZ1er，OIS)感度。
如图4所示，图4中通过带箭头的虚线示意光线R的路径。设置了所述第二透镜9913后，所述第二透镜9913可以将光线R进行扩束，使得由所述第二透镜9913出射的光线R为趋近于平行所述第二方向D2的光线R，此时，即使所述反射元件9911在进行OIS操作时发生移动，这些移动对光线R在所述镜头模块9920上的位置影响相对较小，因为光线R已经预先被扩散，边缘各个位置出射光线R更趋近于平行光线R，进而在所述反射元件9911被驱动以进行光学防抖时，光学系统的MTF的掉落值较小，即OIS感度较小。
也就是，光线R在经过所述光转折模块9910时，先通过所述第一透镜9912进行光线R收束，然后通过所述反射元件9911被反射，再通过所述第二透镜9913进行光线R扩束，然后进入所述镜头模块9920内。这样，有利于缩小所述镜头模块9920内多个透镜的光学有效径，进而减小所述镜头模块9920的高度，降低镜头用驱动元件的肩高，进而也可以降低所述潜望式摄像模组991的总高度。其中，降低镜头用驱动元件的肩高，即，降低镜头用驱动元件的肩高在所述潜望式摄像模组991中所占据的高度空间。
换言之，所述潜望式摄像模组991依靠所述第一透镜9912收束光线R以增大进光量，实现所述潜望式摄像模组991的大光圈。利用所述第二透镜9913扩束光线R以使得光线R以趋近平行于所述第二方向D2入射到所述镜头模块9920，以尽可能地降低MTF的掉落值，提高所述潜望式摄像模组991的成像效果。进一步地，由于光线R经过所述第一透镜9912的收束作用，使得光线R在所述反射元件9911反射后仍处于收束状态，即使光线R经过了所述第二透镜9913的扩束，光线R在进入所述镜头模块9920时的范围也小于光线R进入所述第一透镜9912时的范围，这样，有利于缩小所述镜头模块9920内多个透镜的光学有效径，进而减小所述镜头模块9920的高度，降低镜头用驱动元件的肩高。
相应地，所述第一透镜9912被进一步配置为使得经过其收束后的光线R沿着与所述第一方向D1相交的方向射出；所述第二透镜9913被进一步配置为使得经过其扩束后的光线R沿着趋近于与所述第二方向D2平行的方向射出。
值得一提的是，本申请考虑到所述光转折模块9910的整体重量和尺寸将影响所述潜望式摄像模组991的整体重量和尺寸，且会影响驱动力大小和驱动部件的安装空间，本申请提出：以平面反射镜作为所述反射元件9911，所述平面反射镜具有反射面99111。相比于棱镜，所述平面反射镜的重量较小，甚至所述平面反射镜、所述第一透镜9912和所述第二透镜9913的总重量小于具有同等尺寸所述反射面99111的棱镜的重量，使得所述潜望式摄像模组991能够在实现大光圈的同时尽可能地将所述光转折模块9910的重量和尺寸控制在一定范围内，进而尽可能地不增大所述潜望式摄像模组991的尺寸和重量，还尽可能地不提高对驱动力的要求。
所述反射面99111与所述第一方向D1和所述第二方向D2具有一定夹角，其中，所述反射面99111与所述第一方向D1之间的夹角为30°-60°，所述反射面99111与所述第二方向D2之间的夹角为30°-60°。在本申请的一个示例中，所述反射面99111与所述第一方向D1之间的夹角为45°，所述反射面99111与所述第二方向D2之间的夹角为45°。
所述第一透镜9912沿所述第二方向D2设置，所述第二透镜9913沿所述第一方向D1设置，所述平面反射镜的所述反射面99111与所述第一透镜9912和所述第二透镜9913之间也存在夹角。
为了进一步降低所述反射元件9911的重量，可选地，所述反射元件9911的主要制成材料为树脂材料，或者，其他重量较轻的材料。为了满足所述反射面99111面型的高精度要求，可以通过注塑工艺形成所述反射元件9911。
为了提高成像质量，可选地，可在所述反射面99111上设置高反射膜层。相应地，在本申请的一实施方式中，所述光转折模块9910还包括高反射膜层，所述高反射膜层设置于所述反射元件9911的所述反射面99111。
所述光转折模块9910还包括反射支架9914和转折模块用驱动元件。所述反射支架9914具有支撑部99141、第一安装部99142和第二安装部99143，其中，所述第一安装部99142自所述支撑部99141向所述光转折模块9910的入光侧延伸；所述第二安装部99143自所述支撑部99141向所述光转折模块9910的出光侧延伸。所述反射元件9911被安装于所述支撑部99141，其中，所述支撑部99141具有倾斜面991411，便于所述反射元件9911以特定角度稳定地布置于所述支撑部99141。所述反射元件9911安装于所述支撑部99141的所述倾斜面991411。进一步地，所述倾斜面991411与所述第一方向D1之间具有一定夹角，所述反射面99111与所述第二方向之间具体一定夹角。所述第一透镜9912被安装于所述第一安装部99142。所述第二透镜9913被安装于所述第二安装部99143。所述转折模块用驱动元件被配置为驱动所述反射支架9914移动，进而通过所述反射支架9914带动所述反射元件9911、所述第一透镜9912和所述第二透镜9913移动，以进行光学防抖。
应可以理解，本申请中的所述转折模块用驱动元件可以被实施为音圈(Voice Coil Montor，VCM)马达、线性记忆合金(shape memorY1 alloY1，SMA)马达、压电马达等等，本申请对此不做限制。

在本申请的一个示例中，所述第一镜头组9921为固定镜头组，所述第二镜头组9922为对焦镜头组。相应地，所述第一镜头组9921被固定于所述基座9950；所述第二镜头组9922可活动地设置于所述基座9950。所述第二镜头组9922能够通过镜头用驱动元件被驱动而沿着光轴方向运动，以通过调节所述第一镜头组9921和所述第二镜头组9922的相对位置的方式改变所述潜望式摄像模组991的整体光学性能，同时，所述第二镜头组9922和所述感光芯片9932的相对位置能够被改变，如此，所述潜望式摄像模组991的成像模式能够被切换。
应可以理解，本申请中的所述镜头用驱动元件可以被实施为音圈(Voice Coil Montor，VCM)马达、线性记忆合金(shape memory alloy，SMA)马达、压电马达等等，本申请对此不做限制。
具体地，在所述潜望式摄像模组991中，通过驱动所述第二镜头组9922沿光轴方向移动，所述潜望式摄像模组991能够实现长焦成像模式。当所述潜望式摄像模组991处于所述长焦成像模式时，所述第二镜头组9922距离所述第一镜头组9921较远且距离所述感光芯片9932较近，所述潜望式摄像模组991能够拍摄长距的物体并清晰成像。

根据本申请的另一方面，本申请还提出了一种潜望式摄像模组的组装方法。如图5所示，所述潜望式摄像模组的组装方法被阐明。具体地，本申请采用模块化组装的方式，即，先将光转折模块9910、镜头模块9920和感光模块9930分别独立组装为单独的模块，然后再将模块组装于一体，以形成高度集成化的潜望式摄像模组991。通过上述的模块化组装方式，可以减少各个模块之间的组装公差。
相应地，所述潜望式摄像模组的组装方法包括步骤：S110，分别形成光转折模块9910、镜头模块9920和感光模块9930；S120，将所述镜头模块9920安装于所述光转折模块9910的出光侧；以及，S130，将所述感光模块9930安装于所述镜头模块9920的出光侧。
在步骤S110中，通过本申请提出的光转折模块的组装方法形成所述光转折模块9910。具体地，如图6所示，所述光转折模块的组装方法，包括步骤：S112，将第二透镜9913安装于所述反射元件9911的出光侧，且与所述反射元件9911相间隔，其中，所述第二透镜9913的至少一个侧面具有非平面面型；和，S113，将第一透镜9912安装于所述反射元件9911的入光侧，且与所述反射元件9911相间隔，其中，所述第一透镜9912的至少一个侧面具有非平面面型。所述光转折模块的组装方法，还包括步骤：S111，将反射元件9911安装于反射支架9914。具体地，将所述反射元件9911安装于所述反射支架9914的支撑部99141。
在步骤S112中，将所述第二透镜9913安装于所述反射元件9911的出光侧。具体地，在将所述第二透镜9913安装于所述反射元件9911的出光侧的过程中，将所述第二透镜9913与所述反射元件9911的出光侧对准后，通过粘接介质将所述第二透镜9913粘接固定于所述反射支架9914，以形成光转折模块半成品。更具体地，将所述第二透镜9913固定地安装于所述反射支架9914的第二安装部99143。在步骤S113中，将所述第一透镜9912安装于所述反射元件9911的入光侧。具体地，在申请的一个实施例中，通过主动校准的方式将所述第一透镜9912安装于所述反射元件9911的入光侧。更具体地，在所述第一透镜9912与所述第二透镜9913的相对位置没有确定前，先将所述第一透镜9912、所述反射元件9911、所述第二透镜9913、所述镜头模块9920的第一镜头组9921、所述镜头模块9920的第二镜头组9922和感光芯片9932依次排列，构成待组装的潜望式长焦光学成像系统，然后，对所述感光芯片9932通电，以获取的实测长焦成像结果，进而基于实测长焦成像结果，校准所述第一透镜9912和所述光转折模块半成品的相对位置；最后，基于主动校准后的所述第一透镜9912和所述光转折模块半成品的相对位置，通过粘接介质将所述第一透镜9912固定于所述反射支架9914，以形成所述光转折模块9910。进一步具体地，可通过主动校准的方式将所述第一透镜9912固定地安装于所述反射支架9914的第一安装部99142。值得注意的是，在本申请的该实施例中，所述第一透镜9912和所述第二透镜9913的安装方式不同，所述第一透镜9912在安装过程中通过主动校准的方法进行安装；所述第二透镜9913在安装过程中不进行主动校准。
应可以理解，在组装多个部件的过程中，例如，组装所述第一透镜9912、所述反射元件9911、所述第二透镜9913的过程中，会产生组装公差的累积，而且，所述第一透镜9912、所述第二透镜9913在组装过程中会有倾斜、偏心等情况出现，影响成像效果。在将所述第二透镜9913安装于所述反射元件9911后，通过主动校准的方式来组装所述第一透镜9912能够在组装过程中对成效效果进行补偿，以提高成像质量。
值得一提的是，在本申请的该实施例中，先安装所述第二透镜9913，再通过主动校准的方式安装所述第一透镜9912可以简化组装过程。具体地，所述第二透镜9913设置在所述反射元件9911与所述镜头模块9920之间，受到位于其两侧的所述反射元件9911和所述镜头模块9920之间的空间约束，其调整较为困难，不便于被通过主动校准的方式精细地调整。且由于所述第二透镜9913被沿竖直的方向设置，即，所述第一方向D1设置，在对所述第二透镜9913通过主动校准的方式进行安装时，还需要将用于夹持所述第二透镜9913的设备的夹爪旋转一定的角度，例如，9990度，造成设备更加复杂。如果选择先安装所述第一透镜9912，再通过主动校准的方式安装所述第二透镜9913，无疑会导致操作不便，操作难度和复杂度增加，还容易对其他部件产生影响，特别是与其紧邻的部件。
由于所述第一透镜9912位于所述潜望式摄像模组991的前端，即，靠近被射物体的一端，更便于被设备夹取并调整，并达到较好的校准效果。因此，先安装所述第二透镜9913，再通过主动校准的方式安装所述第一透镜9912的组装方法不仅操作简单，而且能够通过对所述第一透镜9912的主动校准的安装方式对光学系统进行补偿，有利于提高成像效果。
在本申请的另一个实施例中，先组装所述第二透镜9913、所述第一透镜9912和所述反射元件9911，以形成所述光转折模块9910；其中，所述第一透镜9912和所述第二透镜9913的安装顺序不限。在后续对所述光转折模块9910、所述镜头模块9920和所述感光模块9930进行组装的过程中，通过主动校准的方式确定所述光转折模块9910、所述镜头模块9920和所述感光模块9930的位置，并实现光转折模块9910、所述镜头模块9920和所述感光模块9930的组装。在该组装方法中，需要保证所述光转折模块9910、所述镜头模块9920和所述感光模块9930各自的组装精度，然后，再进行主动校准和粘接固定，以提高成像质量。
相应地，在本申请的该实施例中，步骤S110中，通过另一种光转折模块的组装方法形成所述光转折模块9910。另一种光转折模块的组装方法包括步骤：
将所述反射元件9911安装于反射支架9914；
将所述第二透镜9913对准所述反射元件9911的出光侧后通过粘接介质将所述第二透镜9913固定地安置于所述反射支架9914，更具体地，将所述第二透镜9913固定地安装于所述反射支架9914的第二安装部99143；
将所述第一透镜9912对准所述反射元件9911的入光侧后通过粘接介质将所述第一透镜9912固定地安置于所述反射支架9914，更具体地，将所述第一透镜9912固定地安装于所述反射支架9914的第一安装部99142，以形成所述光转折模块9910。
应该可以理解，在另一种光转折模块的组装方法中，并不限定所述第一透镜9912和所述第二透镜9913的安装顺序。也就是，在本申请的一个实施例中，可以先组装所述第二透镜9913于所述反射支架9914，后组装所述第一透镜9912于所述反射支架9914。在本申请的另一个实施例中，可以先组装所述第一透镜9912于所述反射支架9914，后组装所述第二透镜9913于所述反射支架9914。在本申请的再一个实施例中，可以同时组装所述第一透镜9912和所述第二透镜9913于所述反射支架9914，本申请对此不做限制。
所述光转折模块的组装方法，还包括步骤：S114，将光转折模块用驱动元件安装于所述反射支架9914。
综上，根据本申请实施例的光转折模块9910及其组装方法和潜望式摄像模组991及其组装方法被阐明。所述潜望式摄像模组991采用了特定的光学系统设计，使得其能够实现大光圈。
一种反射模块8810，如图7至图18所示，包括：光路转折元件8811，用于将沿第一光轴OA1入射的光线反射至沿第二光轴OA2出射；旋转框架8813，耦接于光路转折元件8811，并支承光路转折元件8811绕第一旋转轴C1转动，其中，第一旋转轴C1平行于第二光轴OA2且与第二光轴OA2不共线；基座8814，用于容纳旋转框架8813；旋转驱动部8817，被配置为驱动旋转框架8813相对于基座8814绕第一旋转轴C1转动；旋转支撑部8815，沿平行于第一光轴OA1方向被压接于旋转框架8813和基座8814之间，并与旋转框架8813和基座8814二者中的至少一个保持摩擦接触；旋转支撑部8815包括沿平行于第一旋转轴C1方向间隔设置的旋转引导轴88151和旋转支撑件88152，第一旋转轴C1穿过旋转引导轴88151的中心和旋转支撑件88152的中心，其中，旋转引导轴88151沿平行于第一旋转轴C1的方向延伸。
应可以理解，当相机被无意地摇晃时(例如由于用户的手抖)，在图像传感器上形成的图像可能不稳定。在这种情况下，根据示例性实施例，潜望摄像模组可以实现用于校正该不稳定图像(即，光学图像稳定，以下称为“光学防抖”)的功能。在一些实施例中，潜望摄像模组可以通过驱动反射模块8810来实现光学防抖功能。
在一些实施例中，光学防抖功能可以通过旋转反射模块8810来实现。例如，当潜望摄像模组抖动时，反射模块8810可以在预定范围内旋转，以光学稳定不稳定的图像。这里，反射模块8810可以绕一个或多个轴进行转动。例如，当光轴平行于第二光轴OA2时，反射模块8810可以围绕平行于第二光轴OA2的第一旋转轴C1进行旋转运动；反射模块8810可以围绕平行于第一光轴OA1的第三旋转轴进行摇摆运动；反射模块8810可以围绕平行于第三轴OA3的第二旋转轴C2进行俯仰运动，其中，第一光轴OA1、第二光轴OA2和第三轴OA3相互垂直。具体地，措辞“摇摆”可以指示反射模块8810的左右摇摆运动，措辞“俯仰”可以指示反射模块8810的上下俯仰运动，措辞“旋转”可以指示反射模块8810的平行于图像传感器的成像面的旋转运动。然而，潜望摄像模组的不稳定图像大多是由用户手抖造成的平行于图像传感器的成像面的旋转抖动，因此针对旋转抖动的补偿对于潜望摄像模组来说更为重要。
倘若驱动旋转框架8813承载光路转折元件8811并带动光路转折元件8811仅实现绕平行于第一光轴OA1的第三旋转轴进行摇摆运动，由于图像传感器的成像面平行于第一光轴OA1和第三轴OA3所在的平面，光阑所在的平面也是平行于第一光轴OA1和第三轴OA3所在的平面，因此在光路转折元件8811绕第三旋转轴进行摇摆运动之后，图像传感器的成像面投影到第一光轴OA1和第三轴OA3所在的平面上时会丢失一部分的成像信息，而且，一部分参与成像的光线在光阑处也会被遮挡，使得光路转折元件8811绕第三旋转轴进行旋转运动过程中的MTF轴值小于物距无穷远(INF状态)时的MTF轴值，即光路转折元件8811绕平行于第一光轴OA1的第三旋转轴进行摇摆运动会引起潜望摄像模组的性能降低，影响最终成像质量。
在本申请中，旋转框架8813得以承载光路转折元件8811并带动光路转折元件8811绕平行于第二光轴OA2的第一旋转轴C1进行旋转运动，使得图像传感器的成像面上的图像可以产生绕第一旋转轴C1进行旋转的效果，进而补偿潜望摄像模组在使用过程中的旋转抖动，起到减少相差，提高成像质量的效果。具体地，由于图像传感器的成像面平行于第一光轴OA1和第三轴OA3所在的平面，光阑所在的平面也是平行于第一光轴OA1和第三轴OA3所在的平面，因此在光路转折元件8811绕第一旋转轴C1旋转运动之后，图像传感器的成像面投影到第一光轴OA1和第三轴OA3所在的平面上时的像面的大小不会改变，像面信息仍然完整，而且，参与成像的光线在光阑处也不会损失。这样，可以使得光路转折元件8811绕第一旋转轴C1的旋转运动时的MTF轴值和物距无穷远(INF状态)时的MTF轴值一致，即光路转折元件8811绕第一旋转轴C1的旋转运动在没有性能降低的情况下可以完全保持相同的图像质量。换言之，光路转折元件8811绕第一旋转轴C1的旋转运动只存在像面角度的旋转，不存在像面高度位置的偏移，因此不影响MTF轴值。其中，MTF称为调制传递函数，是对镜头分辨能力精确、量化评价的可视化表现。
值得一提的是，因为潜望摄像模组的光圈更小，在夜景或视频拍摄时出现抖动使得成像效果会更差。通过旋转框架8813承载光路转折元件8811绕第一旋转轴C1进行旋转运动，还有利于修正潜望摄像模组在低光照环境下和视频拍摄时产生的旋转抖动，进而有利于提高设备的夜景拍摄和视频拍摄的性能，进而得以满足更广泛的使用需求。
在一些实施例中，光路转折元件8811将沿第一光轴OA1入射的光线转折为沿第二光轴OA2出射的光线。光路转折元件8811可以为转折光路的反射镜或棱镜，为了便于描述，本申请的实施例以光路转折元件8811被实施为反射镜为例。
光路转折元件8811包括反射面和安装面，安装面与旋转框架8813耦接以通过旋转框架8813支承光路转折元件8811，反射面相对第一光轴OA1和第二光轴OA2倾斜一定角度延伸。沿第一光轴OA1入射的光线到达反射面后并被反射面转折光路，使得光线沿第二光轴OA2出射。
如前述可知，在本申请中，反射模块8810绕平行于第二光轴OA2的第一旋转轴C1和绕平行于第三轴OA3的第二旋转轴C2转动，分别以第一旋转轴C1和第二旋转轴C2方向校正反射模块8810的姿势，以能够在两个方向上补偿潜望摄像模组的抖动。进一步地，反射模块8810绕第一旋转轴C1的旋转运动结合反射模块8810绕第二旋转轴C2的俯仰运动，有利于使得潜望摄像模组的抖动补偿更加全方向，进而得以更好的补偿由于设备旋转或用户手抖引起的图像模糊，产生更高质量的图像。其中，第一旋转轴C1平行于第二光轴OA2，且第一旋转轴C1与第二光轴OA2不共线；第二旋转轴C2平行于第三轴OA3，在一些实施例中，第二旋转轴C2与第三轴OA3不共线；在另一些实施例中，第二旋转轴C2与第三轴OA3共线。更进一步地，反射模块8810绕第一旋转轴C1进行旋转运动，反射模块8810绕第二旋转轴C2进行俯仰运动。
如图10至图12所示，在一些实施例中，旋转支撑部8815沿平行于第一光轴OA1的方向被压接于旋转框架8813和基座8814之间，并与旋转框架8813和基座8814二者中的至少一个保持摩擦接触，以支撑旋转框架8813在基座8814内绕第一旋转轴C1的旋转运动。具体地，旋转支撑部8815被压接于旋转框架8813的底部和基座8814的上部之间，相较于旋转框架8813和基座8814直接接触，通过旋转支撑部8815被压接于旋转框架8813和基座8814之间，使得旋转支撑部8815得以沿平行于第一光轴OA1方向支撑旋转框架8813，以减小旋转框架8813、旋转支撑部8815和基座8814之间的接触面积，进而有利于减小摩擦力，使得旋转框架8813更为平稳地绕第一旋转轴C1进行旋转运动，还有利于减小旋转框架8813旋转运动时所需的功耗。
在一些实施例中，旋转支撑部8815包括沿第二光轴OA2方向间隔设置的旋转引导轴88151和旋转支撑件88152，其中，第一旋转轴C1穿过旋转引导轴88151的中心和旋转支撑件88152的中心。这样，旋转引导轴88151和旋转支撑件88152可以沿平行于第一旋转轴C1的方向对齐，以使得旋转框架8813可以绕第一旋转轴C1进行转动，提高旋转框架8813的转动精度。
具体地，旋转引导轴88151沿平行于第一旋转轴C1的方向延伸，换言之，旋转引导轴88151在沿平行于第一光轴OA1方向的投影具有与第一旋转轴C1平行的边。这样，当旋转框架8813被驱动绕第一旋转轴C1转动时，旋转框架8813的旋转方向被旋转引导轴88151限制为仅能够实现绕第一旋转轴C1进行转动，而不会存在摇摆运动的干扰，以提高反射模块8810的转动精度。
更具体地，旋转引导轴88151具有沿平行于第一旋转轴C1方向延伸的长度，以使得旋转引导轴88151与旋转框架8813和基座8814二者中的至少一个具有沿平行于第一旋转轴C1方向延伸的摩擦接触线。更进一步地，多条沿平行于第一旋转轴C1方向延伸的摩擦接触线可以组成沿平行于第一旋转轴C1方向延伸的摩擦接触面。换言之，旋转引导轴88151与旋转框架8813和基座8814二者中的至少一个为面摩擦接触或线摩擦接触。
进一步地，旋转引导轴88151为轴对称形状，旋转引导轴88151的对称轴与第一旋转轴C1重合，即旋转引导轴88151相对于第一旋转轴C1为轴对称的结构。例如，旋转引导轴88151可以被实施为圆柱体或圆柱体的一部分。进一步地，旋转支撑件88152为旋转对称形状，旋转支撑件88152具有一平行于第一光轴OA1的旋转对称轴，即旋转支撑件88152相对于旋转对称轴为旋转对称的结构。例如，旋转支撑件88152可以被实施为球或球的一部分。
应可以理解，倘若旋转框架8813与旋转引导轴88151之间仅为点摩擦接触，由于点摩擦接触无法限制旋转框架8813的转动方向，因此当旋转框架8813被驱动绕第一旋转轴C1转动时，旋转框架8813可能会存在绕第三旋转轴转动的摇摆运动趋势，这使得旋转框架8813的旋转运动会存在摇摆运动的干扰，影响反射模块8810的转动精度。
而在本申请中，旋转引导轴88151具有沿平行于第一旋转轴C1方向延伸的长度，以使得旋转引导轴88151与旋转框架8813和基座8814二者中的至少一个具有沿平行于第一旋转轴C1方向延伸的摩擦接触线，进而通过旋转引导轴88151限制旋转框架8813的旋转方向为仅能够实现绕第一旋转轴C1转动，而不会存在摇摆运动的干扰，以提高反射模块8810的防抖精度。
在一些实施例中，旋转引导轴88151具有第一中心轴，第一中心轴穿过旋转引导轴88151的中心。旋转支撑件88152具有第二中心轴，第二中心轴穿过旋转支撑件88152的中心。其中，第一中心轴、第二中心轴和第一旋转轴C1重合。换言之，第一旋转轴C1穿过旋转引导轴88151的中心和旋转支撑件88152的中心。
在一些实施例中，旋转引导轴88151具有沿平行于第一光轴OA1方向延伸的第一高度，旋转支撑件88152具有沿平行于第一光轴OA1方向延伸的第二高度。其中，第一高度等于第二高度，以使得旋转引导轴88151和旋转支撑件88152能够平稳地支撑旋转框架8813，以减小旋转框架8813产生倾斜的风险。
应可以理解，旋转支撑件88152可以与旋转引导轴88151具有相同的结构，也可以具有不同的结构。在本申请中，旋转支撑件88152沿平行于第一光轴OA1的方向延伸，并与旋转框架8813和基座8814二者中的至少一个具有摩擦接触点。更进一步地，多个摩擦接触点可以组成摩擦接触线。换言之，旋转支撑件88152与旋转框架8813和基座8814二者中的至少一个为点摩擦接触或线摩擦接触。由于面摩擦产生的摩擦力大于线摩擦产生的摩擦力，线摩擦产生的摩擦力大于点摩擦产生的摩擦力，因此，本申请中可通过旋转支撑件88152减小旋转框架8813、旋转支撑部8815和基座8814之间的摩擦力，进而减少驱动旋转框架8813绕第一旋转轴C1进行转动所需要的功耗。
进一步地，旋转引导轴88151和旋转支撑件88152的材质可以与旋转框架8813或基座8814的材质相同，例如树脂，旋转引导轴88151和旋转支撑件88152在旋转框架8813或基座8814注塑的过程中一体成型。当然，旋转引导轴88151和旋转支撑件88152的材质也可以是不同材质，例如金属，旋转引导轴88151和旋转支撑件88152嵌入旋转框架8813或基座8814中并通过嵌件注塑工艺一体成型。
如图7、图9和图11所示，在一些实施例中，旋转引导轴88151被实施为凸轴881511，凸轴881511沿平行于第一旋转轴C1的方向延伸，以使得凸轴881511具有沿平行于第一旋转轴C1方向延伸的长度。旋转支撑件88152被实施为凸台881521，凸台881521沿平行于第一光轴OA1的方向延伸。凸轴881511和凸台881521沿平行于第一光轴OA1的方向突出于旋转框架8813和基座8814二者中的一个。进一步地，旋转框架8813和基座8814二者中的另一个设置有导轨88141和导槽88142，以使得凸轴881511被设置于导轨88141中，凸台881521被设置于导槽88142中。这样，凸轴881511沿平行于第一光轴OA1方向与导轨88141的表面摩擦接触；凸台881521沿平行于第一光轴OA1方向与导槽88142的表面摩擦接触。
具体地，凸轴881511具有平行于第二光轴OA2和第三轴OA3所在平面内延伸的第一平面8815111，和沿平行于第一光轴OA1方向突出于第一平面8815111的第一弧面8815112，其中，第一平面8815111与旋转框架8813朝向基座8814一侧的表面一体地连接。基座8814朝向旋转框架8813一侧的表面具有导轨88141，导轨88141沿平行于第一旋转轴C1的方向延伸。凸轴881511的第一弧面8815112与导轨88141的内表面摩擦接触，以通过凸轴881511和导轨88141限定旋转框架8813的转动方向，即当旋转框架8813被驱动绕第一旋转轴C1转动时，旋转框架8813的旋转方向被凸轴881511限制为仅能够实现绕第一旋转轴C1进行转动，而不会存在摇摆运动的干扰，以提高反射模块8810的旋转运动精度。
更具体地，凸台881521具有平行于第二光轴OA2和第三轴OA3所在平面内延伸的第二平面8815211，和沿平行于第一光轴OA1方向突出于第二平面8815211表面的第二弧面8815212，其中，第二平面8815211与旋转框架8813朝向基座8814一侧的表面一体地连接。基座8814朝向旋转框架8813一侧的表面具有导槽88142，凸台881521的第二弧面8815212与导槽88142的内表面摩擦接触，以减小旋转框架8813、旋转支撑部8815和基座8814之间的摩擦力。
在一些实施例中，第一中心轴穿过第一平面8815111上的凸轴881511的中心，第二中心轴穿过第二平面8815211上的凸台881521的中心。其中，第一中心轴与第二中心轴重合并形成第一旋转轴C1。换言之，第一旋转轴C1穿过凸轴881511的中心和凸台881521的中心。
当然，凸轴881511和凸台881521也可以被设置为沿平行于第一光轴OA1方向突出于基座8814朝向旋转框架8813的表面，旋转框架8813朝向基座8814的表面对应地设置有导轨88141和导槽88142，凸轴881511被设置于导轨88141内并与导轨88141的表面摩擦接触，凸台881521被设置于导槽88142内并与导槽88142的表面摩擦接触。进一步地，通过控制凸轴881511、凸台881521、导轨88141和导槽88142的加工精度，有利于提高反射模块8810的组装精度，还有利于提高旋转框架8813的旋转运动的可控性和可靠性。更进一步地，凸轴881511和凸台881521的配合还得以减小旋转框架8813、旋转支撑部8815和基座8814的组装公差，减小组装难度。
如图12所示，在一些实施例中，旋转引导轴88151被实施为滚轴881512，滚轴881512沿平行于第一旋转轴C1方向延伸，以使得滚轴881512具有沿平行于第一旋转轴C1方向延伸的长度，旋转支撑件88152被实施为滚珠881522。滚轴881512和滚珠881522沿平行于第一光轴OA1的方向被压接于旋转框架8813和基座8814之间，进一步地，旋转框架8813朝向基座8814的表面具有第一上导轨881323和第一上导槽881324，基座8814朝向旋转框架8813的表面对应地设置有第一下导轨881411和第一下导槽881421，第一上导轨881323和第一下导轨881411沿平行于第一光轴OA1的方向相对设置，第一上导槽881324和第一下导槽881421沿平行于第一光轴OA1的方向相对设置，滚轴881512被可活动地夹持于第一上导轨881323和第一下导轨881411之间，滚轴881512被可活动地夹持于第一上导槽881324和第一下导槽881421之间。

滚珠881522具有第二弧形表面，第二弧形表面分别与第一上导槽881324的内表面和第一下导槽881421的内表面摩擦接触。这样，不仅减小了摩擦力，还得以减小旋转框架8813、旋转支撑部8815和基座8814的组装公差，减小组装难度。
当然，在一些实施例中，旋转引导轴88151被实施为凸轴881511，旋转支撑件88152被实施为滚珠881522；或者，旋转引导轴88151被实施为滚轴881512，旋转支撑件88152被实施为凸台881521，本申请对此不做限制。
进一步地，上述的凸轴881511、滚轴881512可以被实施为圆柱形、半圆柱形等，上述的凸台881521、滚珠881522可以被实施为球形、半球形等，上述的导轨88141、导槽88142分别可以被实施为四棱锥形、圆柱形、半球形、矩形等形状的槽，本申请对此不做具体限制。
如图9、图10和图13所示，在一些实施例中，旋转驱动部8817包括至少一旋转磁石88171和至少一旋转线圈88172，至少一旋转磁石88171和至少一旋转线圈88172沿平行于第一光轴OA1的方向相对设置，至少一旋转磁石88171和至少一旋转线圈88172相互作用以驱动旋转框架8813绕第一旋转轴C1相对于基座8814转动。其中，至少一旋转磁石88171被设置于旋转框架8813和基座8814二者中的一个，至少一旋转线圈88172被设置于旋转框架8813和基座8814二者中的另一个。
进一步地，旋转框架8813朝向基座8814一侧的表面具有磁石槽，至少一旋转磁石88171被设置于旋转框架8813的磁石槽内。与之对应的，基座8814朝向旋转框架8813一侧的表面具有线圈槽，至少一旋转线圈88172被设置于线圈槽内。这样，可以使得反射模块8810的结构更加紧凑，避免增加反射模块8810的高度。
具体地，至少一旋转磁石88171包括沿平行于第三轴OA3方向间隔设置的第一旋转磁石881711和第二旋转磁石881712，至少一旋转线圈88172包括沿平行于第三轴OA3方向间隔设置的第一旋转线圈881721和第二旋转线圈881722，其中，第一旋转磁石881711和第一旋转线圈881721沿第一光轴OA1方向相对设置，第二旋转磁石881712和第二旋转线圈881722沿平行于第一光轴OA1方向相对设置。当第一旋转线圈881721和第二旋转线圈881722通电后，第一旋转磁石881711和第一旋转线圈881721相互作用，第二旋转磁石881712和第二旋转线圈881722相互作用，以驱动旋转框架8813绕第一旋转轴C1转动。
在一些实施例中，旋转磁石88171与旋转支撑部8815位于旋转框架8813同侧，例如，旋转磁石88171与旋转支撑部8815位于旋转框架8813的底部。进一步地，第一旋转磁石881711、第二旋转磁石881712与旋转支撑部8815位于旋转框架8813的底部，第一旋转磁石881711和第二旋转磁石881712沿平行于第三轴OA3的方向位于旋转支撑部8815的两侧。这样，当第一旋转磁石881711和第二旋转磁石881712产生驱动力时，驱动力作用于旋转支撑部8815的两侧，以通过旋转支撑部8815提供平稳地支撑，使得旋转框架8813能够绕旋转支撑部8815提供的第一旋转轴C1进行转动。
第一旋转磁石881711和第二旋转磁石881712包括沿平行于第一光轴OA1方向布置的第一磁性区和第二磁性区，其中，第一磁性区和第二磁性区磁极设置相反，例如，第一磁性区为N极，第二磁性区为S极。第一旋转磁石881711和第二旋转磁石881712的磁极相对于平行于第二光轴OA2方向对称设置，例如，第一旋转磁石881711的第一磁性区和第二磁性区沿平行于第一光轴OA1的方向叠置，第二旋转磁石881712的第一磁性区和第二磁性区沿平行于第一光轴OA1的方向叠置。第一旋转磁石881711朝向第一旋转线圈881721的一侧为第一磁性区，第一旋转磁石881711远离第一旋转线圈881721的一侧为第二磁性区，第二旋转磁石881712朝向第二旋转线圈881722的一侧为第一磁性区，第二旋转磁石881712远离第二旋转线圈881722的一侧为第二磁性区。进而通过第一旋转磁石881711和第一旋转线圈881721的配合，以及第二旋转磁石881712和第二旋转线圈881722的配合，得以更为可靠、平稳地驱动旋转框架8813相对基座8814绕第一旋转轴C1进行旋转运动。值得一提的是，旋转磁石88171还包括位于第一磁性区和第二磁性区之间的中性区。
进一步地，第一旋转磁石881711和第二旋转磁石881712还可以为多极磁石，即第一旋转磁石881711和第二旋转磁石881712包括多个第一磁性区和第二磁性区。例如，第一旋转磁石881711朝向第一旋转线圈881721的一侧为沿平行于第二光轴OA2方向设置的第一磁性区和第二磁性区，第一旋转磁石881711远离第一旋转线圈881721的一侧为沿平行于第二光轴OA2方向设置的第二磁性区和第一磁性区，其中，第一旋转磁石881711朝向第一旋转线圈881721的一侧的第一磁性区与第一旋转磁石881711远离第一旋转线圈881721的一侧的第二磁性区相对，第一旋转磁石881711朝向第一旋转线圈881721的一侧的第二磁性区与第一旋转磁石881711远离第一旋转线圈881721的一侧的第一磁性区相对。第二旋转磁石881712朝向第二旋转线圈881722的一侧为沿平行于第二光轴OA2方向设置的第一磁性区和第二磁性区，第二旋转磁石881712远离第二旋转线圈881722的一侧为沿平行于第二光轴OA2方向设置的第二磁性区和第一磁性区，其中，第二旋转磁石881712朝向第二旋转线圈881722的一侧的第一磁性区与第二旋转磁石881712远离第二旋转线圈881722的一侧的第二磁性区相对，第二旋转磁石881712朝向第二旋转线圈881722的一侧的第二磁性区与第二旋转磁石881712远离第二旋转线圈881722的一侧的第一磁性区相对。当第一旋转磁石881711和第二旋转磁石881712为多极磁石时，有利于提高旋转磁石88171的磁场强度，提供反射模块8810旋转运动的驱动力。
应可以理解，从平行于第二光轴OA2方向看，在旋转框架8813绕第一旋转轴C1进行旋转运动的过程中，第一旋转磁石881711和第一旋转线圈881721之间的距离的变化与第二旋转磁石881712和第二旋转线圈881722之间的距离的变化相反。具体地，当旋转框架8813绕第一旋转轴C1顺时针转动时，第一旋转磁石881711与第一旋转线圈881721之间的距离增大，第二旋转磁石881712与第二旋转线圈881722之间的距离减小。当旋转框架8813绕第一旋转轴C1逆时针转动时，第一旋转磁石881711与第一旋转线圈881721之间的距离减小，第二旋转磁石881712与第二旋转线圈881722之间的距离增大。
在一些实施例中，旋转磁石88171采用高性能的永磁材料，包括但不限于：钕铁硼永磁材料、铁氧体永磁材料等，以使旋转磁石88171具有较高的磁能积和矫顽力，得以在保证旋转磁石88171具有较强磁力的基础上使得旋转磁石88171具有较小的体积，进而既有利于提高旋转磁石88171和旋转线圈88172之间的驱动力，又有利于使得反射模块8810的结构更为紧凑，有利于减小反射模块8810的整体尺寸。
如图9、图10和图14所示，在一些实施例中，反射模块8810还包括活动载体8812、俯仰支撑部8816和俯仰驱动部8818，其中，光路转折元件8811、活动载体8812、俯仰支撑部8816、旋转框架8813、旋转支撑部8815和基座8814沿平行于第一光轴OA1的方向依次设置。具体地，活动载体8812被可活动地设置于旋转框架8813，活动载体8812可带动光路转折元件8811相对于旋转框架8813绕第二旋转轴C2进行俯仰运动，旋转框架8813可带动活动载体8812和光路转折元件8811相对于基座8814绕第一旋转轴C1进行旋转运动。俯仰支撑部8816被压接于活动载体8812和旋转框架8813之间，第二旋转轴C2穿过俯仰支撑部8816的中心，第二旋转轴C2平行于第三轴OA3，俯仰驱动部8818被配置为驱动活动载体8812带动光路转折元件8811绕第二旋转轴C2进行俯仰运动。应可以理解，沿平行于第一光轴OA1方向，当俯仰支撑部8816的中心所在的高度与光路转折元件8811的中心所在的高度对齐，第二旋转轴C2平行于第三轴OA3且与第三轴OA3共线，以提高活动载体8812绕第二旋转轴C2的转动精度。
当然，在一些实施例中，沿平行于第一光轴OA1方向，当俯仰支撑部8816的中心所在的高度与光路转折元件8811的中心所在的高度不对齐，第二旋转轴C2平行于第三轴OA3且与第三轴OA3不共线，以简化反射模块8810的结构，方便制造。
具体地，活动载体8812包括一体连接的载体主体88121和载体侧壁88122，其中，载体主体88121包括承载部881213、载体背部881211和载体底部881212，承载部881213相对第一光轴OA1和第二光轴OA2倾斜一定角度延伸，光路转折元件8811的安装面被固定于承载部881213，以将光路转折元件8811安置于活动载体8812。载体背部881211位于垂直于第二光轴OA2的平面，载体底部881212位于垂直于第一光轴OA1的平面，载体背部881211所在的平面与载体底部881212所在的平面相互垂直。载体侧壁88122包括沿平行于第三轴OA3方向间隔设置的第一载体侧壁881221和第二载体侧壁881222，第一载体侧壁881221和第二载体侧壁881222分别连接载体背部881211和载体底部881212。进一步地，第一载体侧壁881221和第二载体侧壁881222分别具有自载体底部881212沿第一光轴OA1方向向内凹陷的第一凹部8812211和第二凹部8812221。应可以理解，载体背部881211位于活动载体8812的背部，即沿平行于第二光轴OA2方向远离光路转折元件8811的一侧；载体底部881212位于活动载体8812的底部，即沿平行于第一光轴OA1方向远离光路转折元件8811的一侧。
旋转框架8813包括框架主体88131和自框架主体88131沿第一方向延伸的支撑臂88132，支撑臂88132包括第一支撑臂881321和第二支撑臂881322，其中，第一支撑臂881321和第二支撑臂881322沿第三轴OA3方向间隔设置。应可以理解，框架主体88131在第二光轴OA2和第三轴OA3所在的平面内延伸，第一支撑臂881321和第二支撑臂881322相对于框架主体88131凸起地形成。
进一步地，第一支撑臂881321与第一凹部8812211对应并伸入第一凹部8812211，第二支撑臂881322与第二凹部8812221对应并伸入第二凹部8812221。俯仰支撑部8816被夹持于第一支撑臂881321与第一凹部8812211之间和第二支撑臂881322与第二凹部8812221之间，即第一俯仰支撑件88161被夹持于第一支撑臂881321与第一凹部8812211之间，第二俯仰支撑件88162被夹持于第二支撑臂881322与第二凹部8812221之间，以支撑活动载体8812相对于旋转框架8813绕第二旋转轴C2的转动。
其中，俯仰支撑部8816包括沿平行于第三轴OA3方向间隔设置的第一俯仰支撑件88161和第二俯仰支撑件88162，第一俯仰支撑件88161被夹持于第一支撑臂881321与第一凹部8812211之间，以保持与第一支撑臂881321和第一凹部8812211的摩擦接触；第二俯仰支撑件88162被夹持于第二支撑臂881322与第二凹部8812221之间，以保持与第二支撑臂881322和第二凹部8812221的摩擦接触。第二旋转轴C2延伸的假想线穿过第一俯仰支撑件88161和第二俯仰支撑件88162，以使得第一俯仰支撑件88161和第二俯仰支撑件88162支撑活动载体8812绕第二旋转轴C2进行俯仰运动。其中，第二旋转轴C2平行于第三轴OA3。
在一些实施例中，第一俯仰支撑件88161和第二俯仰支撑件88162被实施为第一俯仰滚珠881611和第二俯仰滚珠881621。进一步地，结合图15所示，第一凹部8812211具有第一上滑槽88122111，第一支撑臂881321具有第一下滑槽8813211，第一上滑槽88122111和第一下滑槽8813211沿第一光轴OA1方向相对设置，第一俯仰滚珠881611可滚动地位于第一上滑槽88122111和第一下滑槽8813211之间；第二凹部8812221具有第二上滑槽88122211，第二支撑臂881322具有第二下滑槽8813221，第二上滑槽88122211和第二下滑槽8813221沿平行于第一光轴OA1的方向相对设置，第二俯仰滚珠881621可滚动地位于第二上滑槽88122211和第二下滑槽8813221之间。
在一些实施例中，第一俯仰支撑件88161和第二俯仰支撑件88162被实施为第一俯仰凸块和第二俯仰凸块。进一步地，第一俯仰凸块和第二俯仰凸块沿平行于第一光轴OA1方向突出于活动载体8812和旋转框架8813二者中的一个，活动载体8812和旋转框架8813二者中的另一个设置有滑槽，第一俯仰凸块和第二俯仰凸块与滑槽的内表面保持摩擦接触。其中，第一俯仰凸块被压接于活动载体8812的第一凹部8812211和旋转框架8813的第一支撑臂881321之间，第二俯仰凸块被压接于活动载体8812的第二凹部8812221和旋转框架8813的第二支撑臂881322之间。
当然，在一些实施例中，第一俯仰支撑件88161被实施为俯仰滚珠881522，第二俯仰支撑件88162被实施为俯仰凸块；或者，第一俯仰支撑件88161被实施为俯仰凸块，第二俯仰支撑件88162被实施为俯仰滚珠881522，本申请对此不做限制。
在一些实施例中，结合图16所示，沿第一光轴OA1方向看，第一俯仰支撑件88161和第二俯仰支撑件88162分别位于旋转引导轴88151和第二旋转支撑部8815的两侧，即旋转引导轴88151和旋转支撑件88152沿第一光轴OA1方向的投影落于第一俯仰支撑件88161和第二俯仰支撑件88162沿第一光轴OA1方向的投影之间，以避免活动载体8812和旋转框架8813受到偏置的支撑力作用而产生倾斜。
进一步地，第一俯仰支撑件88161和第二俯仰支撑件88162沿平行于第一光轴OA1方向投影的连线的假想线，与旋转引导轴88151和旋转支撑件88152沿平行于第一光轴OA1方向投影的连线的假想线相互垂直。这样，可以将旋转框架8813和活动载体8812的运动分解为绕两个相互垂直的第一旋转轴C1和第二旋转轴C2的转动，减小了旋转框架8813和活动载体8812在第三旋转轴的运动分量，进而提高了旋转框架8813和活动载体8812的旋转运动和俯仰运动的驱动精度，还可以减小旋转框架8813和活动载体8812倾斜的风险。
在一些实施例中，俯仰支撑部8816与俯仰驱动部8818位于活动载体8812的异侧，其中，俯仰支撑部8816被设置于活动载体8812的底部，俯仰驱动部8818被设置于活动载体8812的背部，以使得反射模块8810的结构更加紧凑，空间安排更加合理。
如图11、图12、图14和图17所示，在一些实施例中，俯仰驱动部8818包括至少一个俯仰磁石88181和至少一个俯仰线圈88182，至少一个俯仰磁石88181和至少一个俯仰线圈88182沿平行于第二光轴OA2的方向相对设置。其中，至少一个俯仰磁石88181被设置于活动载体8812的载体背部881211，并在载体背部881211沿平行于第三轴OA3方向和平行于第一光轴OA1方向延伸，至少一个俯仰线圈88182被设置于基座8814朝向活动载体8812一侧的表面，并在基座8814朝向活动载体8812一侧的表面上沿平行于第三轴OA3方向和平行于第一光轴OA1方向延伸。至少一个俯仰线圈88182和至少一个俯仰磁石88181相互作用以驱动活动载体8812绕第二旋转轴C2进行俯仰运动。
在一些实施例中，至少一俯仰磁石88181被设置于活动载体8812的背部，至少一旋转磁石88171被设置于所述旋转框架8813的底部，即至少一俯仰磁石88181与至少一旋转磁石88171异侧设置，以避免产生磁干扰。
其中，俯仰磁石88181可以为多极磁石，即俯仰磁石88181包括多个第三磁性区和第四磁性区，其中，第三磁性区和第四磁性区磁极设置相反，例如，第三磁性区为N极，第四磁性区为S极。俯仰磁石88181朝向俯仰线圈88182的一侧为沿平行于第一光轴OA1方向设置的第三磁性区和第四磁性区，俯仰磁石88181远离俯仰线圈88182的一侧为沿平行于第一光轴OA1方向设置的第四磁性区和第三磁性区，其中，俯仰磁石88181朝向俯仰线圈88182的一侧的第三磁性区与俯仰磁石88181远离俯仰线圈88182的一侧的第四磁性区沿平行于第二光轴OA2方向相对设置，俯仰磁石88181朝向俯仰线圈88182的一侧的第四磁性区与俯仰磁石88181远离俯仰线圈88182的一侧的第三磁性区沿平行于第二光轴OA2方向相对设置。当俯仰磁石88181为多极磁石时，有利于提高俯仰磁石88181的磁场强度，提供反射模块8810俯仰运动的驱动力。值得一提的是，俯仰磁石88181还包括位于第三磁性区和第四磁性区之间的中性区。
沿第三轴OA3方向看，在活动载体8812绕第二旋转轴C2进行俯仰运动的过程中，俯仰磁石88181朝向俯仰线圈88182一侧的第三磁性区与俯仰线圈88182之间的距离的变化，与俯仰磁石88181朝向俯仰线圈88182一侧的第四磁性区与俯仰线圈88182之间的距离的变化相反。具体地，当活动载体8812绕第二旋转轴C2顺时针转动时，俯仰磁石88181朝向俯仰线圈88182一侧的第三磁性区与俯仰线圈88182之间的距离增大，俯仰磁石88181朝向俯仰线圈88182一侧的第四磁性区与俯仰线圈88182之间的距离减小。当活动载体8812绕第二旋转轴C2逆时针转动时，俯仰磁石88181朝向俯仰线圈88182一侧的第三磁性区与俯仰线圈88182之间的距离减小，俯仰磁石88181朝向俯仰线圈88182一侧的第四磁性区与俯仰线圈88182之间的距离增大。
当然，俯仰磁石88181也可以单极磁石，即俯仰磁石88181包括一个第三磁性区和第四磁性区，本申请对此不做限制。
在一些实施例中，俯仰磁石88181采用高性能的永磁材料，包括但不限于：钕铁硼永磁材料、铁氧体永磁材料等，以使俯仰磁石88181具有较高的磁能积和矫顽力，得以在保证俯仰磁石88181具有较强磁力的基础上使得俯仰磁石88181具有较小的体积，进而既有利于提高俯仰磁石88181和俯仰线圈88182之间的驱动力，又有利于使得反射模块8810的结构更为紧凑，有利于减小反射模块8810的整体尺寸。
应可以理解，至少一个俯仰磁石88181的数量可以为一个，也可以为两个；与之对应的，至少一个俯仰线圈88182的数量可以为一个，也可以为两个。例如，如图18所示，至少一个俯仰磁石88181的数量为一个，包括第一俯仰磁石881811，第一俯仰磁石881811被设置于活动载体8812的载体背部881211；至少一个俯仰线圈88182的数量为两个，包括第一俯仰线圈881821和第二俯仰线圈881822，第一俯仰线圈881821和第二俯仰线圈881822被设置于基座8814朝向载体背部881211的表面，以使得第一俯仰线圈881821、第二俯仰线圈881822与第一磁石俯仰磁石88181沿平行于第二光轴OA2方向相对设置，第一俯仰线圈881821、第二俯仰线圈881822和第一俯仰磁石881811相互作用以驱动活动载体8812绕第二旋转轴C2进行俯仰运动。
进一步地，第一俯仰线圈881821与第二俯仰线圈881822沿平行于第三轴OA3方向间隔设置，并且沿平行于第二光轴OA2方向，第一俯仰线圈881821与第一俯仰磁石881811的第三磁性区和第四磁性区相对，第二俯仰线圈881822与第一俯仰磁石881811的第三磁性区和第四磁性区相对。这样，可以通过第一俯仰线圈881821与第一俯仰磁石881811和第二俯仰线圈881822与第一俯仰磁石881811之间的相互作用，增加活动载体8812进行俯仰运动时的驱动力，增大活动载体8812绕第二旋转轴C2转动的俯仰角度。
在一些实施例中，俯仰驱动部8818与旋转驱动部8817异侧设置。具体地，俯仰驱动部8818位于光路转折元件8811的背部，旋转驱动部8817位于光路转折元件8811的底部。更具体地，俯仰驱动部8818的俯仰磁石88181被设置于活动载体8812的载体背部881211，旋转驱动部8817的旋转磁石88171被设置于旋转框架8813的底部。这样，一方面，俯仰磁石88181和旋转磁石88171分别被设置于活动载体8812和旋转框架8813，而且分别位于活动载体8812的背部和旋转框架8813的底部，可以避免俯仰磁石88181与旋转磁石88171之间产生磁干扰；另一方向，旋转磁石88171和俯仰磁石88181异侧设置，可以在活动载体8812的背部为俯仰磁石88181提供更大的安置空间，以增大俯仰磁石88181的尺寸，提高俯仰运动时的驱动力，实现更大的俯仰运动角度；再一方面，俯仰磁石88181和旋转磁石88171分别被设置于两个部件上，可以实现俯仰运动和旋转运动的分开驱动，相互之间不易产生干涉。
在一些实施例中，俯仰驱动部8818和俯仰支撑部8816位于活动载体8812的异侧。具体地，俯仰驱动部8818被设置于活动载体8812的载体背部881211，俯仰支撑部8816被设置于活动载体8812的载体底部881212。这样，可以在活动载体8812的背部为俯仰磁石88181提供更大的安置空间，以增大俯仰磁石88181的尺寸，提高俯仰运动时的驱动力，实现更大的俯仰运动角度。而且，通过俯仰驱动部8818和俯仰支撑部8816的配合，得以更为可靠、平稳地驱动活动载体8812相对旋转框架8813绕第二旋转轴C2进行俯仰运动。
在一些实施例中，旋转支撑部8815与旋转驱动部8817位于旋转框架8813的同侧。具体地，旋转支撑部8815和旋转驱动部8817均被设置于旋转框架8813的底部。这样，可以在活动载体8812的背部为俯仰磁石88181提供更大的安置空间，以增大俯仰磁石88181的尺寸，提高俯仰运动时的驱动力，实现更大的俯仰运动角度。进一步地，通过旋转驱动部8817和旋转支撑部8815的配合，得以更为可靠、平稳地驱动旋转框架8813相对于基座8814绕第一旋转轴C1进行旋转运动。
在一些实施例中，如图18所示，至少一旋转磁石88171被设置于活动载体8812和基座8814二者中的一个，至少一旋转线圈88172被设置于活动载体8812和基座8814二者中的另一个，至少一旋转磁石88171和至少一旋转线圈88172沿第一方向相对设置，至少一旋转磁石88171和至少一旋转线圈88172相互作用以驱动旋转框架8813绕第一旋转轴C1相对于基座8814转动。这样，至少一旋转磁石88171和至少一俯仰磁石88181均被活动载体8812，以使得反射模块8810的结构更加紧凑。进一步地，至少一旋转磁石88171和至少一俯仰磁石88181被设置于活动载体8812的不同侧，例如，至少一旋转磁石88171被设置于活动载体8812的底部，至少一俯仰磁石88181被设置于活动载体8812的背部，以避免至少一旋转磁石88171和至少一俯仰磁石88181之间产生磁干扰。
进一步地，活动载体8812的载体底部881212设置有磁石槽，至少一旋转磁石88171被设置于活动载体8812的磁石槽内。与之对应的，基座8814朝向活动载体8812一侧的表面具有线圈槽，至少一旋转线圈88172被设置于线圈槽内。旋转框架8813的框架主体88131的中部具有开口结构，以使得至少一旋转磁石88171和至少一旋转线圈88172得以通过旋转框架8813的开口结构沿平行于第一光轴OA1方向相对设置，这样，可以使得反射模块8810的结构更加紧凑，避免增加反射模块8810的高度。
具体地，至少一旋转磁石88171包括沿平行于第三轴OA3方向间隔设置的第一旋转磁石881711和第二旋转磁石881712，至少一旋转线圈88172包括沿平行于第三轴OA3方向间隔设置的第一旋转线圈881721和第二旋转线圈881722，其中，第一旋转磁石881711和第一旋转线圈881721沿第一光轴OA1方向相对设置，第二旋转磁石881712和第二旋转线圈881722沿平行于第一光轴OA1的方向相对设置。当第一旋转线圈881721和第二旋转线圈881722通电后，第一旋转磁石881711和第一旋转线圈881721相互作用，第二旋转磁石881712和第二旋转线圈881722相互作用，以驱动旋转框架8813绕第一旋转轴C1转动。
如图11至图13所示，在一些实施例中，反射模块8810还包括磁吸磁石88123和磁轭88143，磁吸磁石88123被设置于活动载体8812和基座8814二者中的一个，磁轭88143被设置于活动载体8812和基座8814二者中的另一个。磁吸磁石88123与磁轭88143之间产生沿平行于第一光轴OA1方向的磁吸力，在磁吸力的作用下旋转框架8813得以被夹持于活动载体8812和基座8814之间，俯仰支撑部8816得以被压接于活动载体8812和旋转框架8813之间，旋转支撑部8815得以被压接于旋转框架8813和基座8814之间。
这样，通过磁吸磁石88123和磁轭88143的相互作用，得以向活动载体8812提供沿平行于第一光轴OA1的磁吸力，在磁吸力的作用下活动载体8812、俯仰支撑部8816、旋转框架8813、旋转支撑部8815和基座8814得以被层叠设置。
应可以理解，俯仰支撑部8816和旋转支撑部8815得以在磁吸力的作用下被可靠地夹持于活动载体8812、旋转框架8813和基座8814之间，进而在潜望摄像模组受到例如跌落、撞击等外力的情况下，有利于提高活动载体8812、旋转框架8813和基座8814之间附接的可靠性，得以减小活动载体8812、旋转框架8813和基座8814相脱离的风险。
在一些实施例中，磁轭88143为沿平行于第二光轴OA2和第三轴OA3所在平面上延伸的结构，磁轭88143通过嵌件注塑工艺被内嵌于基座8814内，以减小磁轭88143所占用的空间，进而减小反射模块8810的尺寸。进一步地，活动载体8812的载体底部881212沿平行于第一光轴OA1方向朝向基座8814延伸一突起，旋转框架8813的框架主体88131形成一开口，以使得突起可以穿过开口朝向基座8814延伸。更进一步地，突起的端部向内凹陷形成凹槽，磁吸磁石88123被设置于凹槽内，这样，可以使得磁吸磁石88123的位置更加靠近磁轭88143，以增加磁吸磁石88123与磁轭88143之间产生的磁吸力。
进一步地，沿平行于第三轴OA3方向，磁吸磁石88123被设置于第一旋转磁石881711和第二旋转磁石881712之间，以保持磁吸磁石88123和磁轭88143之间产生的磁吸力对于活动载体8812的作用点位于载体底部881212的中间部位，避免活动载体8812产生倾斜。
如图9、图14和图17所示，在一些实施例中，反射模块8810还包括位置感测组件8819，位置感测组件8819包括至少一旋转感测元件88191和至少一俯仰感测元件88193，其中，至少一旋转感测元件88191用于感测活动载体8812绕第一旋转轴C1转动的信息，至少一俯仰感测元件88193用于感测活动载体8812绕第二旋转轴C2转动的信息。
进一步地，位置感测组件8819还包括至少一旋转感测磁石88192，至少一旋转感测磁石88192被设置于活动载体8812和基座8814二者中的一个，至少一旋转感测元件88191被设置于活动载体8812和基座8814二者中的另一个，至少一旋转感测磁石88192和至少一旋转感测元件88191相对设置，以通过至少一旋转感测元件88191感测至少一旋转感测磁石88192的磁场信息。
其中，至少一旋转感测元件88191包括第一旋转感测元件881911和第二旋转感测元件881912，至少一旋转感测磁石88192包括第一旋转感测磁石881921和第二旋转感测磁石881922，第一旋转感测磁石881921被设置于第一载体侧壁881221朝向基座8814一侧的表面，第一旋转感测元件881911被设置于基座8814朝向第一载体侧壁881221的表面，第一旋转感测磁石881921与第一旋转感测元件881911沿平行于第三轴OA3方向相对设置。第二旋转感测磁石881922被设置于第二载体侧壁881222朝向基座8814一侧的表面，第二旋转感测元件881912被设置于基座8814朝向第二载体侧壁881222的表面，第二旋转感测磁石881922与第二旋转感测元件881912沿平行于第三轴OA3方向相对设置。
应可以理解，活动载体8812在绕第一旋转轴C1进行旋转运动时，可能会存在绕第二旋转轴C2进行俯仰运动的干扰，进而会影响旋转感测元件88191的感测精度。因此，为了提高旋转感测元件88191的感测精度，需要降低活动载体8812绕第一旋转轴C1进行旋转运动时可能存在的绕第二旋转轴C2进行俯仰运动的干扰。
具体地，第一旋转感测元件881911获取第一旋转磁石881711的第一旋转磁场信息T1，第二旋转感测元件881912获取第二旋转磁石881712的第二旋转磁场信息T2，得以通过第一旋转磁场信息T1与第二旋转磁场信息T2计算获得活动载体8812绕第一旋转轴C1转动的信息，并排除活动载体8812绕第二旋转轴C2转动的信息干扰。在活动载体8812绕第一旋转轴C1进行旋转运动的过程中如果存在绕第二旋转轴C2的俯仰运动，第一旋转感测元件881911与第一旋转磁石881711之间存在一定的倾斜角度，第二旋转感测元件881912与第二旋转磁石881712之间存在一定的倾斜角度。换言之，第一旋转感测元件881911沿平行于第一光轴OA1方向的中线与第一旋转感测磁石881921沿平行于第一光轴OA1的中线不平行，第二旋转感测元件881912沿平行于第一光轴OA1方向的中线与第二旋转感测磁石881922沿平行于第一光轴OA1方向的中线不平行。这会导致第一旋转感测元件881911和第二旋转感测元件881912的感测结果易于受到活动载体8812绕第二旋转轴C2转动的影响。
在本申请中，通过第一旋转感测元件881911和第二旋转感测元件881912的配合，得以减小感测活动载体8812在绕第一旋转轴C1进行旋转运动的过程中存在的绕第二旋转轴C2的俯仰运动的影响。具体的，第一旋转感测元件881911得以获取第一旋转感测磁石881921的第一旋转磁场信息T1，第二旋转感测元件881912得以获取第二旋转感测磁石881922的第二旋转磁场信息T2，计算活动载体8812绕第一旋转轴C1进行旋转运动的中心值Tm，Tm＝(T1+T2)/2；进一步的，第一旋转感测元件881911获取的关于活动载体8812绕第一旋转轴C1进行旋转运动的行程信息为T1-Tm，第二旋转感测元件881912获取的关于活动载体8812绕第一旋转轴C1进行旋转运动的行程信息为T2-Tm；更进一步的，活动载体8812绕第一旋转轴C1进行旋转运动的行程信息为(T1-Tm)+(T2-Tm)，即第一旋转感测元件881911和第二旋转感测元件881912获取的活动载体8812绕第一旋转轴C1进行旋转运动的行程信息之和。
应可以理解，在活动载体8812同时存在绕第一旋转轴C1的旋转运动和绕第二旋转轴C2的俯仰运动时，第一旋转磁场信息T1和第二旋转磁场信息T2中会包含有绕第二旋转轴C2的俯仰运动的行程信息，并且第一旋转磁场信息T1中包含的俯仰运动的行程信息与第二旋转磁场信息T2中包含的俯仰运动的行程信息相反，进而通过计算(T1+T2)/2得以抵消俯仰运动的行程信息，以使得Tm中不再存在俯仰运动的行程信息的干扰，有利于提高第一旋转感测元件881911和第二旋转感测元件881912的感测结果的精确性，进而有利于实现对反射模块8810的更为精准的闭环控制。
值得一提的是，前文所述的(T1+T2)、(T1-Tm)、(T2-Tm)、(T1-Tm)+(T2-Tm)并非简单直接相加减，而是包含复杂的算法处理过程的。具体的，计算转动角度的过程可能包括但不限于：881.对磁场信息的数据预处理步骤，例如将第一旋转感测元件881911和第二旋转感测元件881912的输出信号转化为数字信号，对信号进行滤波和放大等处理；882.对数据进行中心化处理或者零均值化处理，或者进行平移处理；883.根据反射系统所处的外界环境对检测结果进行校准；884.在计算过程中调试优化算法。

具体的计算方法可参考第一旋转磁场信息T1与第二旋转磁场信息T2的计算方式，本申请不再进行赘述。
进一步地，旋转感测元件88191可以被设置于旋转线圈88172的内部，以减小旋转感测元件88191所占用的空间，为旋转线圈88172提供更大的空间位置。当然，旋转感测元件88191也可以被设置于旋转线圈88172的外部，以减小旋转线圈88172通电后对俯仰感测元件88193产生的干扰，有利于提高旋转感测元件88191的感测精度。

具体地，如图18所示，俯仰感测元件88193被设置于第一俯仰线圈881821和第二俯仰线圈881822之间，俯仰感测元件88193与俯仰磁石88181沿平行于第二光轴OA2方向相对设置。这样，一方面可以通过俯仰感测元件88193对俯仰磁石88181的俯仰运动进行感测；另一方面可以减小第一俯仰线圈881821和第二俯仰线圈881822通电后产生的磁场对俯仰感测元件88193的干扰，以实现提高俯仰感测元件88193的感测精度。
值得一提的是，反射模块8810也可以包括俯仰感测磁石，俯仰感测磁石被设置于活动载体8812的载体背部881211，俯仰感测元件88193被设置于基座8814朝向载体背部881211一侧的表面，以使得俯仰感测磁石与俯仰感测元件88193沿平行于第二光轴OA2的方向相对设置，以通过俯仰感测元件88193获取俯仰感测磁石的磁场信息。进一步地，俯仰磁石88181和俯仰感测磁石分开设置，得以减小俯仰磁石88181的磁场对俯仰感测磁石的磁场的影响，有利于提高俯仰感测元件88193的感测精度。
进一步地，俯仰感测元件88193可以被设置于俯仰线圈88182的内部，以减小俯仰感测元件88193所占用的空间，为俯仰线圈88182提供更大的空间位置。当然，俯仰感测元件88193也可以被设置于俯仰线圈88182的外部，以减小俯仰线圈88182通电后对俯仰感测元件88193产生的影响，有利于提高俯仰感测元件88193的感测精度。
更进一步地，旋转感测磁石88192、旋转磁石88171、俯仰感测磁石和俯仰磁石88181可以分别被设置于活动载体8812的不同侧，有利于避免磁石之间的相互干扰，进而提高反射模块8810的驱动精度和控制精度。
值得一提的是，旋转感测元件88191和俯仰感测元件88193可以使用相同的元件，也可以使用不同的元件，例如霍尔、驱动IC、TMR、或旋转陀螺仪等。
在一些实施例中，旋转感测元件88191和俯仰感测元件88193的数量和为至少三个，得以通过计算提高旋转感测元件88191和俯仰感测元件88193的感测精度，提高反射模块8810的闭环控制精度。
在一些实施例中，反射模块8810还包括驱动电路，驱动电路电连接于旋转线圈88172、俯仰线圈88182、旋转感测元件88191和俯仰感测元件88193并提供电流，使得旋转线圈88172和旋转磁石88171相互配合以驱动旋转框架8813绕第一旋转轴C1进行旋转运动，以及使得俯仰线圈88182和俯仰磁石88181相互配合以驱动活动载体8812绕第二旋转轴C2进行俯仰运动。进一步地，还可以使得旋转感测元件88191和俯仰感测元件88193感测旋转框架8813和活动载体8812的行程信息，以提高反射模块8810的闭环控制精度。值得一提的是，驱动电路可以被实施为嵌入于基座8814的导电金属嵌件，也可以被实施为贴附于基座8814的柔性线路板，本申请对此不做具体限制。
在一些实施例中，反射模块8810还包括缓冲部，缓冲部包括第一缓冲件，第一缓冲件设置于活动载体8812和旋转框架8813二者中的至少一个，使得第一缓冲件位于活动载体8812和旋转框架8813之间，在活动载体8812绕第二旋转轴C2进行俯仰运动的过程中，第一缓冲件首先与活动载体8812或旋转框架8813接触，进而得以起到缓冲的作用，避免活动载体8812和旋转框架8813直接碰撞，有利于保护活动载体8812和旋转框架8813，以降低活动载体8812和旋转框架8813受损的风险，延长反射模块8810的使用寿命。此外，第一缓冲件间隔于活动载体8812和旋转框架8813之间，得以起到小噪音的效果，有利于提高用户体验。
具体地，第一缓冲件被设置于活动载体8812的载体底部881212朝向旋转框架8813的表面，第一缓冲件也可以被设置于旋转框架8813朝向活动载体8812的载体底部881212的表面，以使得活动载体8812绕第二旋转轴C2进行俯仰运动的过程中，第一缓冲件首先与活动载体8812或旋转框架8813接触，进而得以起到缓冲的作用。

进一步地，第二导磁件88102通过嵌件注塑工艺一体成型于旋转框架8813，第二导磁件88102的至少一部分位于旋转磁石88171远离旋转线圈88172的一侧。这样，第二导磁件88102可以使得旋转磁石88171的磁力更加集中，避免旋转磁石88171的磁力外溢，增加旋转磁石88171的磁场强度。
具体地，第一导磁件88101包括第一导磁部881011、第二导磁部881012、第三导磁部881013和第四加强部881014，第一导磁部881011在平行于第一光轴OA1和第三轴OA3所在的平面内延伸，第一导磁部881011被设置于俯仰磁石88181远离俯仰线圈88182的一侧，以通过第一导磁部881011使得俯仰磁石88181的磁力更加集中，避免俯仰磁石88181的磁力外溢，增加俯仰磁石88181的磁场强度，进而提高驱动活动载体8812绕第二旋转轴C2转动时的驱动力。
第二导磁部881012自第一导磁部881011所在的平面沿平行于第二光轴OA2的方向弯折，第二导磁部881012在平行于第一光轴OA1和第二光轴OA2所在的平面内延伸。第二导磁部881012的数量为两个，两个第二导磁部881012分别被设置于第一旋转感测磁石881921远离第一旋转感测元件881911的一侧，和第二旋转感测磁石881922远离第二旋转感测元件881912的一侧。以通过第二导磁部881012件使得第一旋转感测磁石881921和第二旋转感测磁石881922的磁力更加集中，避免第一旋转感测磁石881921和第二旋转感测磁石881922的磁力外溢，增加第一旋转感测磁石881921和第二旋转感测磁石881922的磁场强度，进而提高旋转感测元件88191的感测精度。
第三导磁部881013自第一导磁部881011所在的平面沿平行于第二光轴OA2方向和平行于第一光轴OA1方向进行两次弯折，第三导磁部881013在平行于第二光轴OA2和第三轴OA3所在的平面内延伸。第三导磁件被设置于磁吸磁石88123远离磁轭88143的一侧，以通过第三导磁件使得磁吸磁石88123的磁力更加集中，避免磁吸磁石88123的磁力外溢，增加磁吸磁石88123的磁场强度，进而提高磁吸磁石88123与磁轭88143之间产生的磁吸力。

应可以理解，第一导磁部881011、第二导磁部881012、第三导磁部881013和第四加强部881014可以为一体式结构，也可以为分体式结构。
具体地，第二导磁件88102在平行于第二光轴OA2和第三轴OA3所在的平面内延伸，第二导磁件88102被设置于旋转磁石88171远离旋转线圈88172的一侧，以通过第二导磁件88102使得旋转磁石88171的磁力更加集中，避免旋转磁石88171的磁力外溢，增加旋转磁石88171的磁场强度，进而提高驱动活动载体8812绕第一旋转轴C1转动时的驱动力。
值得一提的是，第一导磁件88101和第二导磁件88102可以不含有磁性，如第一导磁件88101和第二导磁件88102可以由铁氧体制成，或者，第一导磁件88101和第二导磁件88102本身可以为永磁体。
在一些实施例中，反射模块8810还包括第一透镜，第一透镜被活动载体8812支撑靠近物侧设置，第一光轴OA1穿过光路转折元件8811和第一透镜，活动载体8812适于承载并带动第一透镜和光路转折元件8811同步地绕第一旋转轴C1进行旋转运动和/或同步地绕第二旋转轴C2进行俯仰运动。
应可以理解，活动载体8812承载并带动第一透镜和光路转折元件8811同步绕第一旋转轴C1进行旋转运动和/或同步地绕第二旋转轴C2进行俯仰运动，有利于减小潜望摄像模组的整体尺寸。具体的，倘若仅驱动光路转折元件8811绕第一旋转轴C1和/或绕第二旋转轴C2进行转动，而第一透镜固定不动，则第一透镜需要通过基座8814固定于光路转折元件8811的入光侧，为了避免活动载体8812旋转时与第一透镜产生干涉，需要在第一透镜和活动载体8812之间预留较大的间隙，这势必会导致反射模块8810的高度尺寸增加。并且由于基座8814具有较大的尺寸，进而导致第一透镜可能需要较大的尺寸才能适配安装于基座8814，不利于实现潜望摄像模组的小型化和轻量化。
本申请中，第一透镜安装于活动载体8812，由于活动载体8812的尺寸小于基座8814，因而第一透镜采用较小的尺寸即得以实现安装固定，有利于减小第一透镜的尺寸，以及减轻第一透镜的重量。此外，第一透镜和光路转折元件8811之间无需预留较大的间隙以供光路转折元件8811单独转动，即第一透镜和光路转折元件8811之间的间隙得以更小，有利于使得反射模块8810的结构更为紧凑。
在一些实施例中，第一透镜具有至少一凸面，使得第一透镜具有正光焦度，以用于对光线收束。值得一提的是，第一透镜界定第一光轴OA1。应可以理解，沿第一光轴OA1的光线在经过第一透镜后被收束，得以在不改变潜望摄像模组的物理光阑孔径的基础上起到增加进光量的作用，也就是说，等效于增大潜望摄像模组的有效光圈。
进一步地，经过第一透镜收束的光线在被光路转折元件8811反射后仍保持收束的状态，因而有利于减小潜望摄像模组的镜头模块8820中的各个光学透镜沿第一光轴OA1方向的尺寸，进而得以降低潜望摄像模组的肩高，有利于实现潜望摄像模组的小型化。
更进一步地，光线经过第一透镜收束后入射至光路转折元件8811，使得收束后的光线在光路转折元件8811上的最边缘位置的反射点更靠近第一光轴OA1，也就是说，相较于光线平行入射至光路转折元件8811，本申请所需的光路转折元件8811的反射面的面积更小，有利于减小光路转折元件8811的尺寸，得以降低潜望摄像模组的总高。
在一些实施例中，第一透镜为非切边透镜，有利于降低第一透镜的加工难度，进而降低反射模块8810的生产成本。在另一些实施例中，第一透镜为切边透镜，有利于减小反射模块8810沿平行于第一光轴OA1方向的尺寸。本申请对此不做具体限制。
在一些实施例中，活动载体8812和旋转框架8813适于承载并带动第一透镜和光路转折元件8811同步地绕第一旋转轴C1进行旋转运动和/或同步地绕第二旋转轴C2进行俯仰运动，使得第一透镜和光路转折元件8811之间的相对位置和相对角度稳定。也就是说，光线在经过第一透镜入射至光路转折元件8811的过程中，可以保持光线的传播路径和传播角度的稳定性，不仅有利于提高潜望摄像模组的成像清晰度，还有利于增强潜望摄像模组的图像整体质量。
在本申请中，活动载体8812和旋转框架8813适于承载并带动第一透镜和光路转折元件8811同步地绕第一旋转轴C1进行旋转运动和/或绕第二旋转轴C2进行俯仰运动，使得光线在第一透镜和光路转折元件8811之间的传播路径和角度稳定，进而有利于减小光线在传播至感光模块8830时光线聚焦位置的移动量，得以提高潜望摄像模组的最终成像质量。
值得一提的是，通过活动载体8812承载第一透镜和光路转折元件8811同步运动，还得以减少在防抖操作过程中需要考虑的变量，有利于简化驱动结构以及提高可靠性，并且得以降低反射模块8810以及潜望摄像模组的研发难度和制造难度，有利于降低时间成本和生产成本。
在一些实施例中，活动载体8812包括支架，支架一体或分体地设置于活动载体8812。具体的，支架具有第一固定部，用于安装第一透镜，活动载体8812得以带动支架同步地绕第一旋转轴C1进行旋转运动和/或同步地绕第二旋转轴C2进行俯仰运动，进而使得第一透镜和光路转折元件8811同步运动。
在一些实施例中，第一固定部与活动载体8812的承载部881213之间界定第一空隙，第一透镜的至少部分伸入第一空隙内，进而在沿平行于第一光轴OA1的方向上，使得第一固定部、第一透镜、光路转折元件8811和活动载体8812的排布更为紧凑，有利于减小反射模块8810沿平行于第一光轴OA1方向的尺寸，得以减小潜望摄像模组的高度。
在一些实施例中，反射模块8810还包括第二透镜，第二透镜被活动载体8812支撑靠近像侧设置，第二光轴OA2穿过光路转折元件8811和第二透镜，光路转折元件8811被活动载体8812支撑位于第一透镜和第二透镜之间，以将物侧入射的光线反射至像侧，活动载体8812适于承载并带动第一透镜、光路转折元件8811和第二透镜同步地绕第一旋转轴C1进行旋转运动和/或同步地绕第二旋转轴C2进行俯仰运动，参考上述第一透镜和光路转折元件8811同步运动的内容，不再赘述。
在一些实施例中，第二透镜具有至少一凹面，使得第二透镜具有负光焦度，以用于对光线扩束。值得一提的是，第二透镜界定第二光轴OA2。具体地，第二透镜具有负光焦度，得以对光线进行扩束，使得沿第二光轴OA2的光线在经过第二透镜后被扩束。
应可以理解，通过设置具有扩束作用的第二透镜，经由第一透镜收束的光线得以在经过第二透镜被扩散，增加了到达感光芯片的光线的覆盖面积，进而光路转折元件8811的运动行程对光线在图像传感器上的位置影响相对较小。潜望摄像模组的单位抖动角度下MTF设计值与静态下MTF设计值之间的差值较小，使得潜望摄像模组在运动、振动或抖动的使用场景下得以获取更为清晰的图像。
在一些实施例中，支架还具有和第一固定部相连的第二固定部，用于安装第二透镜，进而使得第一透镜、光路转折元件8811和第二透镜同步运动，参考上述内容，不再赘述。
在一些实施例中，提供一种潜望摄像模组，包括上述的反射模块8810，用于将沿第一光轴OA1入射的光线反射至沿第二光轴OA2出射；镜头模块8820，被配置为接收来自反射模块8810的光线并将光线继续沿第二光轴OA2传播；感光模块8830，感光模块8830被配置为接收光线并进行成像；基体8850，基体8850具有容置腔，反射模块8810和镜头模块8820被设置于容置腔内，反射模块8810的基座8814一体或分体设置于基体8850；以及壳体8840，壳体8840罩设于基体8850。
在一些实施例中，镜头模块8820包括沿第二光轴OA2依次设置的多个透镜，多个透镜中的至少一个可以被驱动在基体8850的容置腔内沿平行于第二光轴OA2方向移动，以实现光学变焦和/或光学对焦功能。当然，多个透镜中的至少一个可以被固定于基体8850的容置腔内，本申请对此不做限制。
进一步地，镜头模块8820还可以包括对焦驱动马达，以驱动多个透镜中的至少一个沿平行于第二光轴OA2方向移动，其中，对焦驱动部可以被实施为VCM马达、SMA马达或压电马达。
在一些实施例中，感光模块8830包括线路板、图像传感器和多个电子元件。具体的，图像传感器和多个电子元件电连接于线路板，图像传感器用于接收反射模块8810采集的外界光线成像，并且通过线路板与外部的电子设备电连接。应可以理解，多个电子元件包括但不限于电阻、电容等无源电子器件和驱动芯片、存储芯片等。
进一步地，感光模块8830还包括一滤光组件，滤光组件包括一滤光元件，滤光元件用于对进入图像传感器的入射光线进行过滤，以滤除入射光线中例如红外光线等成像不需要的杂光。应可以理解，滤光元件被保持于图像传感器的感光路径上，并且设置于镜头模块8820和图像传感器之间。
更进一步地，滤光组件还包括一滤光支架，滤光支架具有一通光孔，滤光元件被安装固定于滤光支架，并且与图像传感器的至少部分感光区域相对应，穿过镜头模块8820的入射光线通过通光孔入射至图像传感器。其中，滤光元件可以被正贴或者倒贴于滤光支架。滤光支架被固定于线路板。值得一提的是，感光模块8830通过滤光支架固定于滤光元件的像侧；感光模块8830也可以通过芯片线路板固定于滤光元件的像侧，本申请对此不作具体限制。
一种反射模块771，如图19-图33所示，包括：反射元件7711、固定组件7760、活动组件7720、驱动组件7780和支承件7762，反射元件7711用于将沿第一方向X入射的光线反射至第二方向Y。固定组件7760具有内部空间7761，活动组件7720被可活动地设置于内部空间7761内，以承载反射元件7711；驱动组件7780被配置为驱动活动组件7720相对于固定组件7760绕第二方向Y旋转；支承件7762被设置于固定组件7760和活动组件7720之间，沿着第二方向Y延伸的假想线穿过支承件7762。在至少一个实施例中，沿着第二方向Y延伸的假想线穿过支承件7762和反射元件7711。
应可以理解，摄像模组抖动是摄像模组的意外运动，例如，当摄像模组被手持操作时而产生的。为了减少潜望摄像模组生成的图像中的抖动影响，通常对上下摇摆和左右摇摆进行补偿，如图20所示。然而，在潜望摄像模组的使用过程中，设备旋转、倾斜或是由用户手抖造成的大多为平行于成像模块的成像面的转动，因此针对旋转抖动的补偿对于潜望摄像模组来说更为重要。
本申请中，如图21所示，活动组件7720得以承载反射元件7711并带动反射元件7711绕第二方向Y旋转，使得成像模块77105的成像面上的图像产生绕第二方向Y旋转的效果，进而得以补偿摄像模组772在使用过程中的旋转抖动和倾斜抖动，起到减少相差，提高成像质量的效果。在本申请中，反射元件7711绕第二方向Y的旋转运动能够实现旋转方向的补偿，其中，由于像面位于第一方向X和第三方向Z所在的平面，光阑所在平面也是第一方向X和第三方向Z所在的平面，反射元件7711绕第二方向Y之后的像面投影到原先的第一方向X和第三方向Z所在的平面上并不会影响到像面的大小，同时参与成像的光线在光阑处也不会损失，进而使得反射元件7711绕第二方向Y的旋转运动时的MTF轴值和物距无穷远(INF状态)时的MTF轴值一致，即反射元件7711绕第二方向Y的旋转运动在没有性能降低的情况下完全保持相同的图像质量。换言之，反射元件7711绕第二方向Y的旋转运动只存在像面角度的旋转，不存在像面高度位置的偏移，因此不影响MTF轴值。其中，MTF(Modulation Transfer Function)称为调制传递函数，是对摄像模组772分辨能力精确、量化评价的可视化表现。
然而，驱动反射元件7711绕第一方向X的旋转运动能够实现左右摇摆方向的补偿，其中，由于像面位于第一方向X和第三方向Z所在的平面，反射元件7711绕第一方向X之后的像面投影到原先的第一方向X和第三方向Z所在的平面上，这会导致像面的信息会丢失一部分。进一步地，由于光阑所在平面也是第一方向X和第三方向Z所在的平面，反射元件7711绕第二方向Y的旋转运动并不会损失有益光线，但反射元件7711绕第一方向X的旋转运动会使得原先一部分参与成像的光线被挡住，进而使得反射元件7711绕第一方向X的旋转运动时的MTF轴值小于物距无穷远(INF状态)时的MTF轴值，即反射元件7711绕第一方向X的旋转运动会降低性能，影响图像质量。
值得一提的是，因为潜望摄像模组772的光圈更小，在夜景或视频拍摄时出现抖动使得成像效果会更差。通过活动组件7720承载反射元件7711绕第二方向Y旋转，还有利于修正摄像模组772在低光照环境下和视频拍摄时产生的旋转和抖动，进而有利于提高设备的夜景拍摄和视频拍摄的性能，进而得以满足更广泛的使用需求。
在一些实施例中，如图22和图23所示，固定组件7760、支承件7762和活动组件7720依次沿第二方向Y层叠设置，支承件7762支撑活动组件7720相对固定组件7760绕第二方向Y旋转。也就是说，固定组件7760和活动组件7720分别位于支撑件的沿第二方向Y的相对两侧，支承件7762得以使固定组件7760和活动组件7720沿第二方向Y保持间隔设置，有利于避免活动组件7720绕第二方向Y旋转的过程中与固定组件7760产生干涉。应可以理解，相较于固定组件7760和活动组件7720直接接触，本实施例中，支承件7762夹设于固定组件7760和活动组件7720之间，进而支承件7762得以沿第二方向Y支撑活动组件7720，减小固定组件7760、支承件7762和活动组件7720之间的接触面积，进而有利于减小摩擦力，使得活动组件7720更为顺滑得绕第二方向Y旋转。
在一些实施例中，如图23和图24所示，反射模块771还包括辅助支撑部7772，支承件7762沿第二方向Y凸出于固定组件7760或活动组件7720，以在固定组件7760和活动组件7720的相对面形成支点，辅助支撑部7772可活动地安装于固定组件7760和活动组件7720之间，以支撑活动组件7720绕支点旋转。也就是说，固定组件7760和活动组件7720中的一者设有支承件7762，支承件7762得以与固定组件7760和活动组件7720中的另一者相抵，以形成支点，进而活动组件7720得以绕支点相对固定组件7760旋转。应可以理解，支承件7762在固定组件7760和活动组件7720之间起到了转轴的作用，以使得活动组件7720相对固定组件7760绕第二方向Y旋转。
进一步地，如图26-图29所示，固定组件7760和活动组件7720中的另一者设有转轴槽77511，转轴槽77511用于容置支承件7762，得以对支承件7762起到限位作用，使得活动组件7720稳定地相对固定组件7760绕第二方向Y旋转。更进一步地，辅助支撑部7772与支承件7762相配合，得以为活动组件7720提供支撑平面，以平稳支撑活动组件7720的运动。
在一些实施例中，如图26所示，辅助支撑部7772包括两个辅助滚珠77721，支承件7762至少部分偏离两个辅助滚珠77721的连线，进而使得支承件7762的支点和两个辅助滚珠77721的支点，三个支点不共线，有利于更稳定地支撑活动组件7720。应可以理解，两个辅助滚珠77721的支点是指辅助滚珠77721与活动组件7720的接触点，或辅助滚珠77721与固定组件7760的接触点。
在一些实施例中，支承件7762的中心至两个辅助滚珠77721中心的距离相等，使得支承件7762的支点至两个辅助滚珠77721的支点的距离相等，进而有利于使支承件7762和辅助滚珠77721提供的支撑力在活动组件7720上分布更为均匀，以提高活动组件7720在绕第二方向Y旋转时的稳定性和可靠性，减小活动组件7720因受力不均而产生歪斜的风险，进而有利于提高反射模块771的可控性，以及提高摄像模组772的成像质量。
在一些实施例中，如图26和图27所示，活动组件7720设有至少二辅助前槽77512，固定组件7760设有至少二辅助后槽7763，辅助前槽77512和辅助后槽7763沿第二方向Y相对设置，辅助滚珠77721可活动地被夹持于辅助前槽77512和辅助后槽7763之间，得以限制至少二辅助滚珠77721在活动组件7720和固定组件7760之间的位置。
在一些实施例中，至少二辅助前槽77512和至少二辅助后槽7763中的一者是直线槽，并且沿以第二方向Y的假想线为圆心的虚拟圆的切线方向延伸，也就是说，在沿第二方向Y上，虚拟圆的圆心的投影与支承件7762的中心的投影重合或趋近重合。应可以理解，支承件7762与转轴槽77511之间的限位关系提供了活动组件7720绕第二方向Y旋转的转轴，至少二辅助滚珠77721仅起到在固定组件7760上辅助支撑活动组件7720的作用，至少二辅助前槽77512和至少二辅助后槽7763中的一者设置为直线槽得以降低加工难度，有利于提高生产效率以及降低生产成本。进一步地，为减小由于辅助滚珠77721而产生的阻力，辅助滚珠77721被松配地容置于直线槽，辅助滚珠77721与直线槽最少状态下仅一点接触，辅助滚珠77721与直线槽最多状态下仅三点接触。
在一个具体实施例中，直线槽具有两个长边槽壁和两个短边槽壁，两个长边槽壁相对设置，两个短边槽壁分别连接两个长边槽壁，两个长边槽壁相互平行且分别沿虚拟圆的切线方向延伸。两个短边槽壁与两个长边槽壁的连接处可以为弧形连接，也就是说，直线槽为圆角矩形的形状，进而有利于降低直线槽的加工难度。进一步地，圆角矩形可以避免辅助滚珠77721在撞击到短边槽壁与长边槽壁的连接处的位置时产生凹坑。
应可以理解，至少二辅助前槽77512和至少二辅助后槽7763中的另一者是圆柱槽、球面槽或者方形槽，以使活动组件7720和固定组件7760中的一者与辅助滚珠77721的接触点保持稳定，进而有利于减小辅助滚珠77721的不规则运动，提高对活动组件7720的支撑的稳定性。
值得一提的是，支承件7762可以被实施为主滚珠，也就是说，固定组件7760和活动组件7720之间设有一个主滚珠和至少两个辅助滚珠77721，以用于支撑活动组件7720，并使得活动组件7720相对固定组件7760绕第二方向Y旋转。
在另一些实施例中，辅助滚珠77721可以设置为三个及以上，对应的，辅助前槽77512和辅助后槽7763也相应设置为三个及以上，本申请对此不做具体限制。
在一些实施例中，如图22-图25所示，活动组件7720包括旋转板7750和活动载体7730，活动载体7730和旋转板7750沿第二方向Y依次设置于固定组件7760，活动载体7730上具有倾斜设置的装载面77321，装载面77321用于固定反射元件7711，以使活动载体7730承载并带动反射元件7711一同旋转。反射模块771还包括转轴支撑部7771，转轴支撑部7771设置于旋转板7750和活动载体7730之间，以支承活动载体7730相对旋转板7750绕第三方向Z旋转运动，其中，第三方向Z垂直于第一方向X和第二方向Y。
其中，反射元件7711绕第三方向Z的旋转运动结合反射元件7711绕第二方向Y的旋转运动，可以提供更加全方向的抖动补偿，可以更好的补偿由于设备旋转或用户手抖引起的图像模糊。
应可以理解，活动组件7720整体相对固定组件7760绕第二方向Y旋转，以使得反射元件7711绕第二方向Y旋转，进而成像面上的图像得以绕沿第二方向Y延伸的假想线旋转，起到补偿由设备旋转或者用户手抖引起的图像模糊。进一步地，活动载体7730相对旋转板7750绕第三方向Z旋转，以使得反射元件7711绕第三方向Z旋转，进而成像面上的图像得以绕沿第三方向Z延伸的假想线旋转，进一步提高摄像模组772的防抖效果，以减少像差，提高图像质量。
在一些实施例中，如图30和图31所示，活动载体7730包括主体部7732、第一侧部7733和第二侧部7734。具体的，装载面77321倾斜的设置于主体部7732，第一侧部7733和第二侧部7734沿第三方向Z相对设置地位于主体部7732的两侧，使得第一侧部7733、第二侧部7734和装载面77321之间形成容纳腔7731，容纳腔7731用于容置反射元件7711。
进一步地，如图31所示，第一侧部7733和第二侧部7734的朝向固定组件7760的表面，分别凹陷地形成一第一凹槽77331和一第二凹槽77341。旋转板7750包括板体7751、第一支架部7752和第二支架部7753，具体的，第一支架部7752和第二支架部7753沿第三方向Z相对设置地位于板体7751的两侧，并且从板体7751向活动载体7730沿第二方向Y延伸，使得第一支架部7752伸入第一侧部7733的第一凹槽77331中，第二支架部7753延伸入第二侧部7734的第二凹槽77341中，进而旋转板7750得以支撑活动载体7730。应可以理解，旋转板7750的第一支架部7752和第二支架部7753既得以在第二方向Y上对活动载体7730起到支撑作用，还得以在第一方向X上对活动载体7730起到支撑作用，有利于避免活动载体7730脱离旋转板7750，提高活动载体7730、旋转板7750以及固定组件7760之间的连接可靠性。
在一些实施例中，如图31所示，转轴支撑部7771包括至少二转轴滚珠77711，旋转板7750设有至少二转轴后槽7754，活动载体7730设有至少二转轴前槽7735，转轴前槽7735和转轴后槽7754沿第二方向Y相对设置，使得转轴滚珠77711可活动地夹持于转轴前槽7735和转轴后槽7754之间，并且至少二转轴滚珠77711被沿着第三方向Z的假想线穿过，以支撑活动载体7730相对旋转板7750绕第三方向Z的转动。在至少一个实施例中，沿着第三方向Z延伸的假想线穿过两个转轴滚珠77711和反射元件7711。
应可以理解，在活动载体7730和旋转板7750之间设置转轴滚珠77711，有利于减小活动载体7730和旋转板7750之间的摩擦力，使得活动载体7730相对旋转板7750绕第三方向Z的转动更为顺滑，同时有利于减小驱动活动载体7730旋转所需的驱动力，进而得以提高活动载体7730绕第三方向Z旋转的稳定性和可靠性。

应可以理解，辅助前槽77512和转轴后槽7754分别位于旋转板7750的板体7751沿第二方向Y的相对两侧，辅助前槽77512用于和固定组件7760上的辅助后槽7763配合以夹持辅助滚珠77721，进而辅助滚珠77721和支承件7762得以配合共同支撑旋转板7750和活动载体7730，使得旋转板7750和活动载体7730绕穿过支承件7762的沿第二方向Y延伸的假想线旋转；转轴后槽7754用于和活动载体7730上的转轴前槽7735配合以夹持转轴滚珠77711，进而两个转轴滚珠77711得以支撑活动载体7730，使得活动载体7730绕穿过转轴滚珠77711的沿第三方向Z延伸的假想线旋转。
在一些实施例中，如图26和图31所示，反射模块771还包括磁吸磁石77373和磁轭7764，磁吸磁石77373被设置于固定组件7760和活动载体7730二者中的一个，磁轭7764被设置于固定组件7760和活动载体7730二者中的另一个，磁吸磁石77373与磁轭7764之间产生沿第二方向Y的磁吸力，在磁吸力的作用下活动载体7730被支撑于旋转板7750。也就是说，通过磁吸磁石77373和磁轭7764的相互作用，得以向活动载体7730提供沿第二方向Y朝向固定组件7760的磁吸力，在磁吸力的作用下旋转板7750被支撑于活动载体7730和固定组件7760之间。应可以理解，磁吸力还有利于使辅助滚珠77721夹持于旋转板7750和固定组件7760之间，以及有利于使转轴滚珠77711夹持于活动载体7730和旋转板7750之间，并且在摄像模组772受到外力的情况下，有利于提高活动载体7730、旋转板7750和固定组件7760之间附接的可靠性，减小活动载体7730、旋转板7750和固定组件7760相脱离的风险。
在一些实施例中，如图26和图31所示，活动载体7730还包括第一延伸部77371和第二延伸部77372，第一延伸部77371和第二延伸部77372沿第三方向Z相对设置，第一延伸部77371和第二延伸部77372位于主体部7732沿第二方向Y朝向固定组件7760的表面，并且第一延伸部77371和第二延伸部77372沿第二方向Y延伸。旋转板7750的板体7751上开设有沿第二方向Y贯穿的避让孔77513，避让孔77513适于使第一延伸部77371和第二延伸部77372穿过，使得第一延伸部77371和第二延伸部77372与固定组件7760沿第二方向Y相对设置。进一步地，磁吸磁石77373设置于第一延伸部77371的末端和第二延伸部77372的末端，固定组件7760上设置有与磁吸磁石77373相对的磁轭7764。通过磁吸磁石77373和磁轭7764的相互作用，得以使活动载体7730和旋转板7750沿第二方向Y层叠地附接于固定组件7760。

在一个具体实施例中，如前文所述，活动载体7730的第一侧部7733的外表面和第二侧部7734的外表面各设有一个第一驱动磁石77811。进一步地，两个第一感测元件7792设置于固定组件7760上沿第三方向Z与活动载体7730相对的内表面，使得两个第一感测元件7792与两个第一驱动磁石77811沿第三方向Z分别相对设置，使得所述第一感测元件7792获取所述第一驱动磁石77811的第一磁场信息，以感测活动载体7730绕第二方向Y旋转的行程。也就是说，第一驱动磁石77811同时用作第一感测磁石7791，即其中一个第一驱动磁石77811用作第一旋转感测磁石77911，另一个第一驱动磁石77811用作第二旋转感测磁石77912，以减少反射模块771的零件数量，降低反射模块771的生产成本。
进一步地，第一驱动磁石77811的磁极沿第一方向X具有较长的尺寸，进而在活动载体7730绕第二方向Y旋转的过程中，第一感测元件7792得以始终与第一驱动磁石77811保持相对设置，使得第一感测元件7792始终位于第一驱动磁石77811的磁场区域内，有利于提高第一感测元件7792的感测结果的精确性，实现对反射模块771更好的闭环控制。
值得一提的是，第一感测元件7792可以被设置于第一驱动线圈77812外，以减小第一驱动线圈77812产生的磁场对第一感测元件7792的影响，有利于提高第一感测元件7792的感测精度；第一感测元件7792也可以被设置于第一驱动线圈77812内，以使得反射模块771的结构更为紧凑，本申请对此不作具体限制。
在另一个具体实施例中，第一旋转感测磁石77911以独立于第一驱动磁石77811的方式被设置于第一侧部7733，第二旋转感测磁石77912以独立于第一驱动磁石77811的方式被独立设置于第二侧部7734，以减小第一驱动磁石77811和第一驱动线圈77812之间的磁场对第一感测磁石7791的磁场的影响，有利于提高第一感测元件7792的感测精度。
在一个具体实施例中，如图25所示，如前文所述，主体部7732的底面设有一个第二驱动磁石77821。进一步地，第二感测元件7794设置于固定组件7760上沿第一方向X与活动载体7730相对的内表面，使得第二感测元件7794与第二驱动磁石77821沿第一方向X相对设置，使得所述第二感测元件7794获取所述第二驱动磁石77821的第二磁场信息，以感测活动载体7730绕第三方向Z旋转的行程。也就是说，第二驱动磁石77821同时用作第二感测磁石7793，以减少反射模块771的零件数量，降低反射模块771的生产成本。
进一步地，第二驱动磁石77821的磁极沿第二方向Y具有较长的尺寸，进而在活动载体7730绕第三方向Z旋转的过程中，第二感测元件7794得以始终与第二驱动磁石77821保持相对设置，使得第二感测元件7794始终位于第二驱动磁石77821的磁场区域内，有利于提高第二感测元件7794的感测结果的精确性，实现对反射模块771更好的闭环控制。
值得一提的是，第二感测元件7794可以被设置于第二驱动线圈77822外，以减小第二驱动线圈77822产生的磁场对第二感测元件7794的影响，有利于提高第二感测元件7794的感测精度；第二感测元件7794也可以被设置于第二驱动线圈77822内，以使得反射模块771的结构更为紧凑，本申请对此不作具体限制。
在另一个具体实施例中，第二旋转感测磁石77912以独立于第二驱动磁石77821的方式被设置于主体部7732的底侧，以减小第二驱动磁石77821和第二驱动线圈77822之间的磁场对第二感测磁石7793的磁场的影响，有利于提高第二感测元件7794的感测精度。
应可以理解，第一旋转感测磁石77911、第二旋转感测磁石77912分别设置于活动载体7730的第一侧部7733和第二侧部7734，第二感测磁石7793设置于活动载体7730的底侧，也就是说，第一旋转感测磁石77911、第二旋转感测磁石77912和第二感测磁石7793分别设置于活动载体7730的不同侧，有利于避免各个感测磁石的磁场相互干扰，有利于提高感测组件7790的感测精度，进而得以提高反射模块771的控制的精准性和可靠性。
在一些实施例中，如图26和图31所示，反射模块771还包括缓冲件77201，缓冲件77201包括第一缓冲部772011，第一缓冲部772011设置于活动载体7730和旋转板7750二者中的至少一个，使得第一缓冲部772011位于活动载体7730和旋转板7750之间，在活动载体7730绕第三方向Z旋转的过程中，第一缓冲部772011首先与活动载体7730或旋转板7750接触，进而得以起到缓冲的作用，避免活动载体7730与旋转板7750碰撞，有利于保护活动载体7730和旋转板7750，以降低活动载体7730和旋转板7750受损的风险，延长摄像模组772的使用寿命。此外，第一缓冲部772011间隔于活动载体7730和旋转板7750之间，得以起到小噪音的效果，有利于提高用户体验。
在一些实施例中，如图23和图27所示，缓冲件77201还包括第二缓冲部772012，第二缓冲部772012设置于旋转板7750和固定组件7760二者中的至少一个，使得第二缓冲部772012位于旋转板7750和固定组件7760之间，在旋转板7750绕第二方向Y旋转的过程中，第二缓冲部772012首先与旋转板7750或固定组件7760接触，进而得以起到缓冲的作用，避免旋转板7750和固定组件7760碰撞，有利于保护旋转板7750和固定组件7760，以降低旋转板7750和固定组件7760受损的风险，延长摄像模组772的使用寿命。此外，第二缓冲部772012间隔于旋转板7750和固定组件7760之间，得以起到小噪音的效果，有利于提高用户体验。
在一些实施例中，如图25、图28和图30所示，缓冲件77201还包括第三缓冲部772013，第三缓冲部772013设置于活动载体7730和固定组件7760二者中的至少一个，使得第三缓冲部772013位于活动载体7730和固定组件7760之间，在活动载体7730沿第一方向X运动的过程中，第三缓冲部772013首先与活动载体7730或固定组件7760接触，以避免活动载体7730与固定组件7760相撞。应可以理解，在摄像模组772跌落的情况下，跌落冲击较大可能造成活动载体7730脱离固定组件7760，进而导致活动载体7730与固定组件7760产生碰撞。也就是说，第三缓冲部772013得以起到缓冲作用，避免活动载体7730与固定组件7760相撞，有利于保护活动载体7730和固定组件7760，以降低活动载体和固定组件7760受损的风险，延长摄像模组772的使用寿命。此外，第三缓冲部772013间隔于活动载体7730和固定组件7760之间，得以起到减小噪音的效果，有利于提高用户体验感。
在一些实施例中，如图25和图28所示，第三缓冲部772013可被设置于活动载体7730的底部和固定组件7760之间。在一些实施例中，如图30所示，第三缓冲部772013也可以被设置于活动载体7730的顶部与固定组件7760之间。
在一些实施例中，如图24所示，反射模块771还包括第一透镜7712和第二透镜7713，第一透镜7712被活动组件7720支撑靠近物侧设置，第二透镜7713被活动组件7720支撑靠近像侧设置，反射元件7711被活动组件7720支撑位于第一透镜7712和第二透镜7713之间，以将物侧入射的光线反射至像侧，活动组件7720适于承载并带动第一透镜7712、反射元件7711和第二透镜7713同步地绕第二方向Y和/或同步地绕第三方向Z转动。
应可以理解，活动组件7720承载并带动第一透镜7712、反射元件7711和第二透镜7713同步地绕第二方向Y和/或同步地绕第三方向Z旋转，有利于减小摄像模组772的整体尺寸。具体的，倘若仅驱动反射元件7711绕第二方向Y和/或绕第三方向Z旋转，而第一透镜7712和第二透镜7713固定不动，则第一透镜7712和第二透镜7713需要通过固定组件7760分别固定于反射元件7711的入光侧和出光侧，并且第一透镜7712、第二透镜7713和活动组件7720之间需要预留较大的间隙，以避免活动组件7720旋转时与第一透镜7712和第二透镜7713产生干涉，但是，这势必会导致反射模块771的高度尺寸和长度尺寸增加。并且在第一透镜7712和第二透镜7713安装于固定组件7760的情况下，由于固定组件7760具有较大的尺寸，进而导致第一透镜7712和第二透镜7713可能需要较大的尺寸才能适配安装于固定组件7760，不利于实现摄像模组772的小型化和轻量化。
而本申请中，第一透镜7712和第二透镜7713安装于活动组件7720，由于活动组件7720的尺寸小于固定组件7760，因而第一透镜7712和第二透镜7713采用较小的尺寸即得以实现安装固定，有利于减小第一透镜7712和第二透镜7713的尺寸，以及减轻第一透镜7712和第二透镜7713的重量。此外，第一透镜7712、反射元件7711和第二透镜7713之间的间隙得以更小，有利于使得反射模块771的结构更为紧凑。
在一些实施例中，如图22所示，第一透镜7712具有至少一凸面，使得第一透镜7712具有正光焦度，以用于对光线收束；第二透镜7713具有至少一凹面，使得第二透镜7713具有负光焦度，以用于对光线扩束。值得一提的是，第一透镜7712界定第一光轴OA1，第二透镜7713界定第二光轴OA2，第一光轴OA1平行于第一方向X，第二光轴OA2平行于第二方向Y。应可以理解，沿第一光轴OA1的光线在经过第一透镜7712后被收束，得以在不改变摄像模组772的物理光阑孔径的基础上起到增加进光量的作用，也就是说，等效于增大摄像模组772的有效光圈。
进一步地，经过第一透镜7712收束的光线在被反射元件7711反射后仍保持收束的状态，因而所需的第二透镜7713的光学有效径也较小，即有利于减小第二透镜7713沿第一方向X的尺寸。并且，镜头模块77101中的各个光学透镜沿第一方向X与第二透镜7713沿第一方向X的尺寸较为接近，因而也有利于减小摄像模组772的镜头模块77101中的各个光学透镜沿第一方向X的尺寸，进而得以降低摄像模组772的肩高，有利于实现摄像模组772的小型化。
更进一步地，相较于光线平行入射至反射元件7711，本申请中，光线经过第一透镜7712收束后入射至反射元件7711，使得收束后的光线在反射元件7711上的最边缘位置的反射点更靠近第一光轴OA1，也就是说，所需的反射元件7711的反射面77131的面积更小，有利于减小反射元件7711的尺寸，得以降低摄像模组772的总高。
在至少一个实施例中，第一透镜7712的物侧面和像侧面均为凸面，使得光线经过第一透镜7712时得以产生两次折射，有利于增强第一透镜7712对光线的汇聚效果，进而减小第一透镜7712和反射元件7711之间的距离，使得反射模块771的结构更为紧凑。
如前文所述，第二透镜7713具有负光焦度，得以对光线进行扩束，使得沿第二光轴OA2的光线在经过第二透镜7713后被扩束。应可以理解，倘若没有第二透镜7713或第二透镜7713不具有扩束的作用，则经过第一透镜7712收束的光线在被反射元件7711反射后，将仍以收束的状态传播至镜头模块77101的各个光学透镜，进而导致到达镜头模块77101的光线的覆盖面积小，可能使摄像模组772都对抖动的反应过于敏感，会降低图像稳定性，导致在拍摄时画面晃动更为严重。
而本申请中，通过设置具有扩束作用的第二透镜7713，经由第一透镜7712收束的光线得以在经过第二透镜7713被扩散，增加了到达镜头模块77101的光线的覆盖面积，进而反射元件7711的运动行程对光线在镜头模块77101上的位置影响相对较小。摄像模组772的单位抖动角度下MTF设计值与静态下MTF设计值之间的差值较小，使得摄像模组772在运动、振动或抖动的使用场景下得以获取更为清晰的图像。
在一些实施例中，如图24所示，第一透镜7712和/或第二透镜7713为非切边透镜，也就是说，第一透镜7712沿第二方向Y的尺寸L771等于沿第三方向Z的尺寸L772；第二透镜7713沿第一方向X的尺寸L773等于沿第三方向Z的尺寸L774，有利于降低第一透镜7712和第二透镜7713的加工难度，进而降低反射模块771的生产成本。
在另一些实施例中，如图24所示，第一透镜7712和/或第二透镜7713为切边透镜，也就是说，第一透镜7712沿第二方向Y的尺寸L771小于沿第三方向Z的尺寸L772。第二透镜7713沿第一方向X的尺寸L773小于沿第三方向Z的尺寸L774，进而有利于减小反射模块771沿第一方向X的尺寸，以及减小反射模块771沿第二方向Y的尺寸。
在一些实施例中，活动组件7720适于承载并带动第一透镜7712、反射元件7711和第二透镜7713同步地绕第二方向Y旋转和/或同步地第三方向Z旋转，使得第一透镜7712、反射元件7711的第二透镜7713之间的相对位置和相对角度稳定。也就是说，光线在经过第一透镜7712入射至反射元件7711，再经由反射元件7711反射至第二透镜7713的过程中，可以保持光线的传播路径和传播角度的稳定性，不仅提高了成像的清晰度，还增强了图像的整体质量。
应可以理解，倘若在进行光学防抖操作时，活动组件7720仅承载反射元件7711绕第二方向Y旋转和/或绕第三方向Z旋转，第一透镜7712和第二透镜7713固定不动，则会导致光线在第一透镜7712和反射元件7711之间的传播路径和角度，以及光线在反射元件7711和第二透镜7713之间的传播路径和角度也会随之变化。可能导致光线在经过第一透镜7712、反射元件7711和第二透镜7713的收束、反射和扩束后产生防抖需求之外的传播路径和角度，进而整个摄像模组772可能出现成像出现像糊、像散或畸变等问题，影响最终成像质量。
然而，在本申请中，活动组件7720适于承载并带动第一透镜7712、反射元件7711和第二透镜7713同步地绕第二方向Y旋转和/或同步地绕第三方向Z旋转，使得光线在第一透镜7712、反射元件7711和第二透镜7713之间的传播路径和角度稳定，进而有利于减小光线在经过镜头模块77101出射至成像模块77105时光线聚焦位置的移动，得以提高摄像模组772的成像质量。此外，通过活动组件7720承载第一透镜7712、反射元件7711和第二透镜7713同步运动，还得以减少在防抖操作过程中需要考虑的变量，有利于降低反射模块771以及摄像模组772的设计难度和制造难度，得以降低人工成本、时间成本和生产成本，以及有利于简化驱动结构以及提高可靠性。
在一些实施例中，如图24和图32所示，活动组件7720还包括支架7740，支架7740一体或分体地设置于活动组件7720的活动载体7730，支架7740具有第一装载部7741和第二装载部7742，第一装载部7741与活动载体7730的装载面77321沿第一方向X相对设置，用于安装第一透镜7712，第二装载部7742与装载面77321沿第二方向Y相对设置，用于安装第二透镜7713，在活动载体7730带动支架7740的情况下，第一透镜7712、反射元件7711和第二透镜7713同步运动。进一步地，活动载体7730和支架7740为一体结构或分体结构。
应可以理解，活动载体7730适于被驱动以相对于旋转板7750绕第三方向Z旋转，支架7740一体或分体地固定于活动载体7730，以使得支架7740和活动载体7730一同绕第二方向Y旋转和/或绕第三方向Z旋转。进一步地，反射元件7711固定于活动载体7730的装载面77321，第一透镜7712固定于支架7740的第一装载部7741，进而使得第一透镜7712和反射元件7711得以沿第一方向X相对设置，光线得以沿第一光轴OA1从第一透镜7712射至反射元件7711。更进一步地，第二透镜7713固定于支架7740的第二装载部7742，进而使得第二透镜7713和反射元件7711得以沿第二方向Y相对设置，光线得以沿第二光轴OA2从反射元件7711射至第二透镜7713。值得一提的是，通过活动载体7730和支架7740得以使第一透镜7712、反射元件7711和第二透镜7713作为整体被驱动以绕第二方向Y旋转和/或绕第三方向Z旋转，有利于简化反射模块771的结构，降低反射模块771的复杂性。
在一个具体实施例中，活动载体7730和支架7740分体设置，以便于分别在活动载体7730上安装反射元件7711，以及在支架7740上安装第一透镜7712和第二透镜7713，有利于降低安装难度，并且两个工序得以同时进行，有利于提高生产效率。
在另一个具体实施例中，活动载体7730和支架7740一体成型，有利于减少零件数量，进而减少安装工序，提高生产效率。
在一些实施例中，如图22和图24所示，第一装载部7741与活动载体7730的装载面77321之间界定第一空间77381，第一透镜7712的至少部分伸入第一空间77381内，进而在沿第一方向X上，使得第一装载部7741、第一透镜7712、反射元件7711和活动载体7730的排布更为紧凑，有利于减小反射模块771的高度，进而减小摄像模组772的总高；第二装载部7742与活动载体7730的装载面77321之间界定第二空间77382，第二透镜7713的至少部分伸入第二空间77382内，进而在沿第二方向Y上，使得活动载体7730、反射元件7711、第二装载部7742和第一透镜7712的排布更为紧凑，有利于减小反射模块771的长度，进而减小摄像模组772的长度。
在至少一个实施例中，如图22和图24所示，反射元件7711被实施为反射镜，包括反射面77131和固定面77132，反射面77131用于反射光线，固定面77132用于和活动载体7730的装载面77321相固定。应可以理解，相较于棱镜，本实施例中的反射镜具有更轻的重量和更小的尺寸，得以减小反射模块771在摄像模组772中的占用空间，有利于实现摄像模组772的小型化。此外，驱动反射镜所需的马达尺寸和动力也更小，并且有利于提高防抖的效果。
具体的，如图22所示，反射镜的反射面77131和第一装载部7741之间具有较大的第一空间77381，以使得第一透镜7712的物侧面得以容纳于第一装载部7741和反射面77131之间的第一空间77381内。同样的，反射面77131和第二装载部7742之间也具有较大的第二空间77382，第二透镜7713的像侧面得以容纳于反射面77131和第二装载部7742之间的第二空间77382内，使得第一透镜7712、反射镜和第二透镜7713的排布更为紧凑，有利于减小反射模块771的整体体积，进而得以减小摄像模组772的整体尺寸。
值得一提的是，反射元件7711也可以被实施为棱镜，本申请对此不作具体限制。
在一些实施例中，如图24和图32所示，支架7740还包括一对支架侧部7743，两个支架侧部7743沿平行于第二轴方向相对设置，支架侧部7743一体连接第一装载部7741和第二装载部7742，有利于提高第一装载部7741和第二装载部7742的连接强度，进而有利于提高支架7740的整体结构强度。进一步地，活动载体7730具有定位部7736，定位部7736与支架侧部7743相安装适配，使得支架7740固接于活动载体7730。应可以理解，通过定位部7736和支架侧部7743相配合得以起到限位的作用，得以提高反射模块771的可靠性。
在至少一个实施例中，如图30所示，定位部7736设置于活动载体7730的第一侧部7733和第二侧部7734，使得支架7740的一个支架侧部7743适于和第一侧部7733相连，支架7740的另一个支架侧部7743适于和第二侧部7734相连，进而支架7740得以架设于活动载体7730，使得第一透镜7712和反射元件7711沿第一方向X相对设置，第二透镜7713和反射元件7711沿第二方向Y相对设置。
在一些实施例中，活动组件7720的旋转中心与活动组件7720的重心趋近重合。值得一提的是，活动组件7720的重心是指第一透镜7712、反射元件7711、第二透镜7713、第一驱动磁石77811、第二驱动磁石77821、第一感测磁石7791、第二感测磁石7793、支架7740和活动载体7730的整体的重心。应可以理解，在第一驱动组件7781和第二驱动组件7782驱动活动组件7720绕第二方向Y和/或绕第三方向Z旋转时，倘若重心与旋转中心的距离较大，进而可能需要克服因重力产生的扭矩，造成驱动所需的电流增大。并且在反射模块771因外力晃动时，因重力产生的扭矩会驱使活动组件7720相对固定组件7760活动，进而可能发出异响，影响用户的使用体验。而本实施例中，活动组件7720的旋转中心与活动组件7720的重心趋近重合，有利于使活动组件7720在不受驱动力时保持稳定，在需要绕第二方向Y和/或绕第三方向Z旋转一进行防抖操作时快速响应，有利于提高反射模块771的可靠性。
进一步地，活动组件7720的旋转中心与反射元件7711的中心重合，使得反射元件7711被驱动绕第二方向Y和/或绕第三方向Z旋转的过程中，反射元件7711得以反射所有进入反射模块771的光线，有利于提高成型效果。应可以理解的，倘若活动组件7720的旋转中心与反射元件7711的中心重合偏差较大，则在反射元件7711旋转后，可能有部分光线无法被反射，或者无法到达成像面，进而摄像模组772的成像像面的裁切角增大，进而影响成像效果。
更进一步地，活动组件7720绕第二方向Y旋转的旋转轴与第二透镜7713界定的第二光轴OA2之间的距离小于0.5mm，优选的，活动组件7720绕第二方向Y旋转的旋转轴与第二光轴OA2重合，得以进一步提高摄像模组772的成像效果。
值得一提的是，支承件7762被沿第二方向Y设置于所述活动载体7730的背侧，沿着第二方向Y的假想线穿过支承件7762、反射元件7711和第二透镜7713；且活动组件7720绕第二方向Y旋转的旋转轴与第二透镜7713界定的第二光轴OA2之间的距离尽可能地同轴。这样能够避免因旋转轴偏移导致的光线非对称性传播，进而避免产生非对称像差。而且，还能够避免边缘视场因光路非对称扭曲产生的相位畸变或局部MTF衰减，实现防抖过程中提高成像质量稳定性的技术效果。
具体地，本申请是在设有第一透镜7712、反射元件7711和第二透镜7713的光学架构基础上设计了适配的驱动方案，以实现反射元件7711和第二透镜7713同步地绕第二方向Y转动，进而实现减小MTF值衰减的效果。
值得一提的是，如果反射模块771仅设置反射元件7711进行反射，而在第二透镜7713反射元件7711的入光侧或出光侧不单独设置透镜，反射模块771仅对光线进行反射，而不会通过曲面结构或折射介质对光线产生偏折作用。由于棱镜或反射镜本身不具备光焦度，其旋转运动仅改变光路的传播方向而不会影响光线的会聚状态。因此，当驱动棱镜或反射镜绕第一方向X转动时，或绕第二方向Y转动时，光线的传播不会产生畸变，从而使得调制传递函数(MTF)的数值保持稳定。这种特性使得反射模块771仅设置反射元件7711的潜望式光学防抖系统在补偿抖动时，无需考虑因棱镜转动引入的像差或光路偏移，最终确保成像分辨力与画面清晰度不会因防抖动作而产生可观测的下降。
换言之，对于反射模块771仅设置反射元件7711的潜望摄像模组来说，仅配置棱镜或反射镜对光线反射，且入光侧与出光侧未设置独立透镜，即常规潜望摄像模组仅改变光线的传播方向而不改变光学特性以维持成像功能。其中，棱镜或反射镜不论绕哪个轴线转动以进行光学防抖时，由于未引入面型或折射介质对光线进行偏折，其转动过程中不会因光学路径的变化导致调制传递函数(MTF)值下降，从而保障了成像质量的稳定性。
而本申请的反射模块771在第二透镜7713反射元件7711的入光侧设置了第一透镜7712，在第二透镜7713反射元件7711的出光侧设置了第二透镜7713，且第二透镜7713第二透镜7713因其扩束作用显著降低了光学防抖过程中的MTF值的衰减，是提升动态成像稳定性的关键设计。如果第二透镜7713反射元件7711与第二透镜7713第二透镜7713被同步驱动以补偿抖动，第二透镜7713第二透镜7713的旋转方向将直接影响光路的偏折方向和偏折角度，从而在动态场景中引入残余像差或局部MTF值下降，进而影响光学防抖的成像效果。
更具体地，由于第二透镜7713位于反射元件7711像侧的光路上，第二透镜7713绕第一方向X的转动使得光线在感光芯片的长度方向进行偏移，进而使得光线在水平方向发生非对称性偏移。具体表现为：中心视场左右两侧的边缘光线在通过旋转后的第二透镜7713时，因透镜对光线的偏折作用，其光线的出射方向产生偏差，导致光线在进入镜头模块77101时呈现左右分散不均衡的状态。这种非对称的光线分布会破坏镜头模块77101对不同视场光线的均匀接收，尤其在动态补偿过程中，边缘视场的光线偏移量被进一步放大，最终导致调制传递函数(MTF)的数值出现显著衰减。换言之，第二透镜7713绕第一方向X的旋转虽能补偿机械抖动，但会因第二透镜7713的旋转方向引入额外的光学像差，使得动态MTF值相比静态设计值产生更大程度的下降，即MTF的掉点高，进而导致图像清晰度劣化。
反射元件7711和第二透镜7713绕第二方向Y转动相当于在平行于感光芯片的平面内进行旋转，只存在像面角度的旋转，不存在像面高度位置的偏移。由于第二透镜7713本身结构的对称性，第二透镜7713对光线的扩束作用在水平方向上仍保持对称性，中心视场左右两侧的边缘光线经过旋转后的第二透镜7713时，光线的出射角度与传播方向未受额外干扰，仍能维持接近原始设计的光路对称状态。这种对称性确保了光线在进入镜头模块77101时，使得光线的覆盖范围及光线分布均匀性得以保留，从而避免因非对称偏移导致的相位畸变或像差放大。因此，在不同视场下，MTF的掉点小。换言之，第二透镜7713绕第二方向Y的旋转既实现了抖动补偿，又规避了光线传播的非对称扰动，最终使MTF值维持在较高水平，成像质量不受动态场景的影响。
相应地，在本申请实施例中，支承件7762被沿第二方向Y设置于所述活动载体7730的背侧，沿着第二方向Y的假想线穿过支承件7762、反射元件7711和第二透镜7713，通过将旋转的第二方向Y约束于贯穿支承件7762、反射元件7711和第二透镜7713，能够避免因旋转轴偏移导致的光线非对称性传播，进而避免产生非对称像差。而且，支承件7762、活动组件7720、反射元件7711和第二透镜7713同轴既能够实现抖动补偿功能，又能够避免边缘视场因光路非对称扭曲产生的相位畸变或局部MTF衰减，实现防抖过程中提高成像质量稳定性的技术效果。
一种摄像模组772，如图1和图22所示，包括：如上的反射模块771；镜头模块77101，镜头模块77101被保持于反射模块771的光反射路径上；以及成像模块77105，成像模块77105接收镜头模块77101出射的光线进行成像；基座77106，基座77106具有容置腔771061，反射模块771和镜头模块77101被设置于容置腔771061内，反射模块771的固定组件7760一体或分体设置于基座77106；壳体77107，壳体77107罩设于基座77106。
应可以理解，反射模块771的活动组件7720得以承载反射元件7711并带动反射元件7711绕第二方向Y旋转，使得成像模块77105的成像面上的图像产生绕第二方向Y旋转的效果，进而得以补偿摄像模组772在使用过程中的旋转抖动和倾斜抖动，有利于减少相差，提高摄像模组772的最终成像质量。
在一些实施例中，如图22所示，镜头模块77101包括多个透镜，镜头模块77101用于将光线成像在成像模块77105的成像面上。具体的，镜头模块77101包括第一镜头组771011和第二镜头组771012，第一镜头组771011与第二镜头组771012沿第二光轴OA2方向依次设置。
在一个具体实施例中，第一镜头组771011为固定镜头组，第二镜头组771012为对焦镜头组，也就是说，第一镜头组771011被固定于基座77106，第二镜头组771012被承载于镜头载体77102，通过对焦驱动组件77104得以驱动镜头载体77102承载第二镜头组771012沿第二方向Y运动，进而得以实现潜望式摄像模组772的光学对焦功能，以及切换摄像模组772的成像模式。其中，对焦驱动组件77104包括对焦线圈771041和对焦磁石771042。
在一些实施例中，如图34所示，镜头载体77102沿第三方向Z的一侧设置有一对对焦磁石771042和对焦线圈771041，有利于减小镜头模块77101沿第三方向Z的尺寸，进一步实现摄像模组772的小型化。在另一些实施例中，镜头载体77102沿第三方向Z相对的两侧各设置有一对对焦磁石771042和对焦线圈771041以向镜头载体77102和第二镜头组771012提供更大的驱动力。
应可以理解，镜头模块77101还可以包括第三镜头组和/或第四镜头组，第三镜头组和/或第四镜头组可以沿第二方向Y运动，以实现光学变焦功能，本申请对此不作具体限制。
在一些实施例中，镜头载体77102的底面和基座77106之间设有支持件77103，以支承并引导镜头载体77102相对基座77106沿第二方向Y运动，有利于提高镜头载体77102和基座77106之间相对运动的可靠性，以及减小相对运动时的摩擦阻力。可以理解是，支持件77103可以被实施为导杆或者滚珠，本申请对此不作具体限制。
在一个具体实施例中，如图34所示，镜头载体77102的底面由导杆771031和镜头滚珠771032共同支撑。具体的，基座77106上设有导杆771031，导杆771031沿第二方向Y延伸，镜头载体77102的底面的沿第三方向Z的一侧设有导槽771021，导杆771031适配安装于导槽771021，进而通过导槽771021和导杆771031的配合得以引导镜头载体77102相对基座77106沿第二方向Y移动。进一步的，镜头载体77102的底面还设有至少一镜头滚珠771032，镜头滚珠771032得以与导杆771031配合以为镜头载体77102提供支撑平面，有利于更稳定地支撑镜头载体77102的运动。
在一个具体实施例中，如图35所示，镜头载体77102的底面的沿第三方向Z的一侧设有两个沿第二方向Y间隔设置的镜头滚珠771032，具体的，其中一个镜头滚珠771032紧配于镜头载体77102和基座77106之间，另一个镜头滚珠771032松配于镜头载体77102和基座77106之间。应可以理解，其中一个镜头滚珠771032紧配，进而得以与导杆771031配合以支承镜头载体77102顺滑移动的基础上，另一个镜头滚珠771032松配，进而得以在镜头模块77101受到外力时辅助支承镜头载体77102，也就是说，两个镜头滚珠771032得以分担冲击力，进而降低镜头载体77102、镜头滚珠771032或基座77106受到损坏的风险。
在另一个具体实施例中，镜头载体77102的底面由两根导杆771031支撑。具体地，基座77106上设有两根沿第三方向Z间隔设置的导杆771031，并且两根导杆771031均沿第二方向Y延伸，镜头载体77102的底面设有两个沿第三方向Z间隔设置的导槽771021，导杆771031适配安装于导槽771021，进而通过导杆771031和导槽771021的配合得以支撑镜头载体77102，并且引导镜头载体77102相对基座77106沿第二方向Y移动。
在另一个具体实施例中，镜头载体77102的底面由至少三个镜头滚珠771032支撑。具体地，镜头载体77102的底面的沿第三方向Z的一侧设有至少一个镜头滚珠771032，镜头载体77102的底面的沿第三方向Z的另一侧设有两个沿第二方向Y间隔设置的镜头滚珠771032。应可以理解的，至少三个镜头滚珠771032不共线，得以为镜头载体77102提供支撑平面，有利于更稳定地支撑镜头载体77102的运动。进一步的，为限制至少三镜头滚珠771032在镜头载体77102和基座77106之间的位置，镜头载体77102的底面以及基座77106的面向镜头载体77102的表面分别开设有滚珠槽771022，以容置镜头滚珠771032，进而通过镜头滚珠771032和滚珠槽771022的配合得以支撑镜头载体77102，并且引导镜头载体77102相对基座77106沿第二方向Y移动。
在本申请的另一个实施例中，提供另一种摄像模组772，其包括：如上的反射模块771；镜头模块77101，镜头模块77101被保持于反射模块771的光反射路径上；光路转折元件；以及成像模块77105，成像模块77105的成像面与第一方向X垂直，成像模块77105接收镜头模块77101出射的光线进行成像。在该实施例中，反射元件7711用于将沿第一方向X入射的光线反射至第二方向Y，光路转折元件用于将沿第二方向Y传播的光线反射至沿第一方向X，成像模块77105用于接收来自第一方向X的光线。光路转折元件可以被实施为三棱镜，也可以被实施为反射镜。
可以理解的是，通过在摄像模组772中设置反射元件7711和光路转折元件，可以将光线进行多次反射，通过将光路折叠，可以满足摄像模组772较长的光学镜头总长(TTL)需求。进一步地，反射元件7711可以将光线由第一方向X反射至第二方向Y，光路转折元件可以将光线由第二方向Y反射至第一方向X，从而使得成像模块77105的成像面可以在垂直于第一方向X的平面设置。相对于传统的长焦摄像模组772，本申请中的成像模块77105的成像面可以不用受限于摄像模组772在垂直于第二方向Y上的尺寸限制，成像模块77105的成像面可以实现更大尺寸的设计。
在该实施例中，当第一驱动组件7781驱动活动组件7720和反射元件7711绕第二方向Y旋转运动时，能够实现旋转方向的补偿，应可以理解，像面位于第二方向Y和第三方向Z所在的平面，光阑所在平面也是第二方向Y和第三方向Z所在的平面，反射元件7711绕第二方向Y之后的像面经过光路转折元件反射后投影到原先的第二方向Y和第三方向Z所在的平面上并不会影响到像面的大小，同时参与成像的光线在光阑处也不会损失，进而使得反射元件7711绕第二方向Y的旋转运动时的MTF轴值和物距无穷远(INF状态)时的MTF轴值一致，即反射元件7711绕第二方向Y的旋转运动在没有性能降低的情况下完全保持相同的图像质量。
值得一提的是，镜头模块77101的驱动组件还可以被实施为SMA马达(Small Motor Actuator)、压电马达等，本申请对此不做限制。
在一些实施例中，成像模块77105包括一芯片线路板、感光芯片和多个电子元件。具体的，感光芯片和多个电子元件电连接于芯片线路板，感光芯片用于接收反射模块771采集的外界光线成像，并且通过芯片线路板与外部的电子设备电连接。应可以理解，多个电子元件包括但不限于电阻、电容等无源电子器件和驱动芯片、存储芯片等。
进一步地，成像模块77105还包括一滤光组件，滤光组件包括一滤光元件，滤光元件用于对进入感光芯片的入射光线进行过滤，以滤除入射光线中例如红外光线等成像不需要的杂光。应可以理解，滤光元件被保持于感光芯片的感光路径上，并且设置于镜头模块77101和感光芯片之间。
更进一步地，滤光组件还包括一滤光元件支架，滤光元件支架具有一通光孔，滤光元件被安装固定于滤光元件支架且对应于感光芯片的至少感光区域，穿过镜头模块77101的入射光线通过通光孔入射至感光芯片。具体的，滤光元件可以被正贴或者倒贴于滤光元件支架。
在一个具体实施例中，滤光元件支架被固定于芯片线路板。值得一提的是，感光组件通过滤光元件支架固定于滤光元件的像侧；感光组件也可以通过芯片线路板固定于滤光元件的像侧，本申请对此不作具体限制。
一种反射系统1，如图36-图51所示，包括：反射组件10、活动载体20、旋转支架50、固定组件60、第一驱动组件81和第二驱动组件82。反射组件10包括第一透镜11、反射元件13和第二透镜12。第一透镜11被活动载体20支撑靠近物侧设置，第二透镜12被活动载体20支撑靠近像侧设置，反射元件13被活动载体20支撑位于第一透镜11和第二透镜12之间，以将物侧入射的光线反射至像侧。活动载体20被可活动地设置于旋转支架50。旋转支架50被可活动地设置于固定组件60。第一驱动组件81被配置为驱动旋转支架50相对于固定组件60绕第一轴A1旋转；第二驱动组件82被配置为驱动活动载体20相对于旋转支架50绕第二轴A2旋转。其中，第一轴A1穿过第一透镜11和反射元件13，第三轴A3穿过第二透镜12和反射元件13，第三轴A3垂直于第一轴A1和第二轴A2。
应可以理解，如图36和图37所示，活动载体20承载并带动第一透镜11、反射元件13和第二透镜12同步地绕第一轴A1旋转和/或同步地绕第二轴A2旋转，还有利于减小摄像模组2的整体尺寸。具体的，倘若仅驱动反射元件13绕第一轴A1旋转和/或绕第二轴A2旋转，而第一透镜11和第二透镜12固定不动，则第一透镜11和第二透镜12需要通过固定组件60以进行固定，使得第一透镜11位于反射元件13的入光侧，第二透镜12位于反射元件13的出光侧，并且第一透镜11和活动载体20之间需要预留较大的间隙，第二透镜12和活动载体20之间也需要预留较大的间隙，以避免活动载体20带动反射元件13在绕第一轴A1旋转和/或绕第二轴A2旋转时与第一透镜11和第二透镜12产生干涉，但是，这势必会增加反射系统1沿平行于第一轴A1的尺寸和沿平行于第三轴A3的尺寸，即导致反射系统1的高度尺寸和长度尺寸增加。并且在第一透镜11和第二透镜12安装于固定组件60的情况下，由于固定组件60需要容置活动载体20和其他器件，因而固定组件60具有较大的尺寸，进而导致第一透镜11和第二透镜12可能需要较大的尺寸才能适配安装于固定组件60，造成反射系统1的尺寸进一步增大，反射系统1的重量也会增加，不利于实现摄像模组2的小型化和轻量化。
而本申请中，如图36和图37所示，第一透镜11和第二透镜12安装于活动载体20，由于活动载体20的尺寸小于固定组件60，因而第一透镜11和第二透镜12无需具有较大的尺寸以用于安装固定，有利于减小第一透镜11和第二透镜12的尺寸，以及减轻第一透镜11和第二透镜12的重量。此外，第一透镜11、反射元件13和第二透镜12之间的间隙得以更小，有利于使得反射系统1的结构更为紧凑，进而得以减小摄像模组2沿平行于第一轴A1的尺寸以及沿平行于第三轴A3的尺寸。
在一些实施例中，如图37、图38和图40所示，第一透镜11具有至少一凸面，使得第一透镜11具有正光焦度，以用于对光线收束；第二透镜12具有至少一凹面，使得第二透镜12具有负光焦度，以用于对光线扩束。值得一提的是，第一透镜11界定第一光轴OA1，第二透镜12界定第二光轴OA2，第一光轴OA1平行于第一轴A1，第二光轴OA2平行于第三轴A3。
也就是说，第一透镜11具有正光焦度，得以对光线进行收束，使得沿第一光轴OA1的光线在经过第一透镜11后被收束，得以在不改变摄像模组2的物理光阑孔径的基础上起到增加进光量的作用，也就是说，等效于增大摄像模组2的有效光圈。应可以理解，相较于不具有正光焦度的透镜，本实施例中具有正光焦度的第一透镜11得以在相同的光线条件下，捕获更多的光量，进而有利于提高摄像模组2的成像质量。值得一提的是，增加进光量对提升摄像模组2在低光照环境下的成像质量尤为重要。
进一步的，经过第一透镜11收束的光线在被反射元件13反射后仍保持收束的状态，因而所需的第二透镜12的尺寸也较小，有利于减小第二透镜12沿平行于第一轴A1方向的尺寸。值得一提的是，镜头模块101中的各个光学透镜沿平行于第一轴A1方向的尺寸与第二透镜12沿平行于第一轴A1方向的尺寸较为接近，因而在光线被第一透镜11收束的条件下，也有利于减小摄像模组2的镜头模块101中的各个光学透镜沿平行于第一轴A1方向的光学有效径，进而得以降低摄像模组2的肩高h，有利于实现摄像模组2的小型化，得以迎合电子设备轻薄化的发展趋势。
更进一步的，相较于光线平行入射至反射元件13，本申请中，入射至反射元件13的光线经过第一透镜11收束，使得收束后的光线在反射元件13上的最边缘位置的反射点更靠近第一光轴OA1，也就是说，所需的反射元件13的反射面131的面积更小，有利于减小反射元件13的尺寸，有利于降低摄像模组2的总高H。
在一个具体实施例中，第一透镜11的物侧面为凸面，第一透镜11的像侧面为凸面。在另一个具体实施例中，第一透镜11的物侧面为凸面，第一透镜11的像侧面为凹面。在本申请中，透镜的凸面和凹面根据透镜的中心区域部分的凹凸为依据，即透镜中物侧面向物侧突出为凸面，向像侧突出为凹面；透镜中像侧面向物侧突出为凹面，向像侧突出为凸面。
其中，第一透镜11的物侧面和像侧面均为凸面，使得光线经过第一透镜11时得以产生两次折射，有利于增强第一透镜11对光线的汇聚效果，有利于进一步减小第一透镜11和反射元件13之间的距离，使得反射系统1的结构更为紧凑，有利于实现摄像模组2的小型化。
如前文所述，第二透镜12具有负光焦度，得以对光线进行扩束，使得沿第二光轴OA2的光线在经过第二透镜12后被扩束。应可以理解，倘若没有第二透镜12或第二透镜12不具有扩束的作用，则经过第一透镜11收束的光线在被反射元件13反射后，将仍以收束的状态传播至镜头模块101的各个光学透镜，也就是说，到达镜头模块101前的光线仍处于汇聚状态，进而导致到达镜头模块101的光线的覆盖面积小。在上述情况下，倘若反射元件13在进行光学防抖操作时产生运动，例如绕第一轴A1旋转和/或绕第二轴A2旋转，由于光线较为集中，反射元件13较小行程的运动都易于引起光线在镜头模块101上的相对位置产生较大的变化，从而导致摄像模组2的MTF(Modulation Transfer Function，调制传递函数)的掉落值较大，最终成像的清晰度变差。并且，摄像模组2都对抖动的反应过于敏感，会降低图像稳定性，导致在拍摄时画面晃动更为严重。
而本申请中，通过设置具有扩束作用的第二透镜12，经由第一透镜11收束的光线得以在经过第二透镜12被扩散，增加了到达镜头模块101的光线的覆盖面积。即使反射元件13在进行光学防抖操作时产生运动，由于光线覆盖面积增大，反射元件13的运动行程对光线在镜头模块101上的位置影响相对较小。也就是说，光线在到达镜头模块101前已经被第二透镜12扩散，得以避免光线集中在一个非常小的区域上，进而在反射元件13被驱动以进行光学防抖时，摄像模组2的MTF的掉落值较小，最终成像的清晰度更好。并且，摄像模组2对抖动的反应较为适中，有利于提高图像稳定性，使得在拍摄时画面更为稳定。也就是说，摄像模组2的单位抖动角度下MTF设计值与静态下MTF设计值之间的差值较小，使得摄像模组2在运动或振动的使用场景下得以获取更为清晰的图像。
在一个具体实施例中，第二透镜12的物侧面为凹面，第二透镜12的像侧面为凹面。在另一个具体实施例中，第二透镜12的物侧面为凸面，像侧面为凹面。
在一些实施例中，如图36和图37所示，活动载体20适于承载并带动反射组件10运动，使得第一透镜11、反射元件13和第二透镜12同步地绕第一轴A1旋转和/或同步地绕第二轴A2旋转。也就是说，在进行光学防抖操作时，第一透镜11、反射元件13和第二透镜12均被固定于活动载体20，使得第一透镜11、反射元件13的第二透镜12之间的相对位置和相对角度稳定，当第一透镜11、反射元件13和第二透镜12被驱动一起旋转运动时，使得光线在经过第一透镜11入射至反射元件13，再经由反射元件13反射至第二透镜12的过程中，可以保持光线的传播路径和传播角度的稳定性，不仅提高了成像的清晰度，还增强了图像的整体质量。
应可以理解，倘若在进行光学防抖操作时，活动载体20仅承载反射元件13绕第一轴A1旋转和/或绕第二轴A2旋转，第一透镜11和第二透镜12固定不动，则会导致反射元件13与第一透镜11和第二透镜12之间的相对位置和相对角度产生变化，进而光线在第一透镜11和反射元件13之间的传播路径和角度，以及光线在反射元件13和第二透镜12之间的传播路径和角度也会随之变化。可能导致光线在经过反射组件10的收束、反射和扩束后产生防抖需求之外的传播路径和角度，进而对整个摄像模组2的性能造成不良影响。例如，由于光线的传播路径和角度发生变化，使得光线在经过镜头模块101出射至成像模块105时光线聚焦的位置也产生改变，进而可能导致成像焦点偏离最佳成像平面，造成摄像模组2的最终成像出现像糊、畸变或像散等问题，影响摄像模组2的成像质量。
然而，在本申请中，活动载体20适于承载并带动第一透镜11、反射元件13和第二透镜12同步地绕第一轴A1旋转和/或同步地绕第二轴A2旋转，使得光线在第一透镜11和反射元件13之间的传播路径和角度，以及光线在反射元件13和第二透镜12之间的传播路径和角度稳定，进而有利于减小光线在经过镜头模块101出射至成像模块105时光线聚焦位置的移动，使得成像焦点趋近最佳成像平面，以减小光线的传播路径和传播角度变化而引起的像糊、畸变或像散等成像缺陷，得以提高摄像模组2的成像质量。
相较于仅驱动反射元件13旋转的方案，本申请中，第一透镜11、反射元件13和第二透镜12同步运动的方案得以优化反射系统1的整体性能和可靠性，有利于提高摄像模组2的最终成像的整体质量，有利于在低光照环境下，以及运动或振动的使用场景下实现高质量的图像输出。
值得一提的是，通过活动载体20承载整个反射组件10同步运动，还得以减少在防抖操作过程中需要考虑的变量，进而有利于简化反射系统1的设计。应可以理解，如前文所述，倘若仅驱动反射元件13绕第一轴A1旋转和/或绕第二轴A2旋转，而第一透镜11和第二透镜12固定不动，则可能导致光线在经过反射组件10的收束、反射和扩束后产生防抖需求之外的传播路径和角度，对整个摄像模组2的性能造成不良影响，进而在设计反射系统1时，需要进一步考虑如何弥补或消除由光线的传播路径和角度变化造成的不良影响。
而本申请中，活动载体20驱动反射组件10同步运动，使得光线在第一透镜11和反射元件13之间的传播路径和角度，以及在反射元件13和第二透镜12之间的传播路径和角度保持不变，进而得以避免设置额外的结构或者算法以对光线的传播路径和角度进行优化，有利于降低反射系统1以及摄像模组2的设计难度和制造难度，得以降低人工成本、时间成本和生产成本。此外，第一透镜11、反射元件13和第二透镜12均安装于活动载体20，通过驱动活动载体20即得以实现第一透镜11、反射元件13和第二透镜12的同步运动，有利于简化驱动结构以及提高可靠性。
在一些实施例中，如图37-图40所示，活动载体20包括旋转载体30和安装架40，旋转载体30具有安装面321，安装面321用于固定反射元件13，安装架40具有第一安装部41和第二安装部42，第一安装部41与安装面321沿第一轴A1相对设置，用于安装第一透镜11，第二安装部42与安装面321沿第三轴A3相对设置，用于安装第二透镜12，在旋转载体30带动安装架40的情况下，第一透镜11、反射元件13和第二透镜12同步运动，其中，旋转载体30和安装架40为一体结构或分体结构。
应可以理解，旋转载体30适于被驱动以相对于旋转支架50绕第二轴A2旋转，安装架40一体或分体地固定于旋转载体30，以使得安装架40和旋转载体30一同绕第一轴A1旋转和/或绕第二轴A2旋转。进一步的，反射元件13固定于旋转载体30的安装面321，第一透镜11固定于安装架40的第一安装部41，进而使得第一透镜11和反射元件13得以沿第一轴A1相对设置，光线得以沿第一光轴OA1从第一透镜11射至反射元件13。更进一步的，第二透镜12固定于安装架40的第二安装部42，进而使得第二透镜12和反射元件13得以沿第三轴A3相对设置，光线得以沿第二光轴OA2从反射元件13射至第二透镜12。值得一提的是，通过旋转载体30和安装架40得以使反射组件10作为整体被驱动以绕第一轴A1旋转和/或绕第二轴A2旋转，有利于简化反射系统1的结构，降低反射系统1的复杂性。
在一个具体实施例中，旋转载体30和安装架40分体设置，以便于分别在旋转载体30上安装反射元件13，以及在安装架40上安装第一透镜11和第二透镜12，有利于降低反射组件10的安装难度，并且两个工序得以同时进行，有利于提高生产效率。
在另一个具体实施例中，旋转载体30和安装架40一体成型，有利于减少零件数量，减少安装工序。
在一些实施例中，如图41所示，第一安装部41具有用于安装第一透镜11的第一开口411，第一开口411在平行于第二轴A2和第三轴A3的平面内延伸，第二安装部42具有用于安装第二透镜12的第二开口421，第二开口421在平行于第一轴A1和第二轴A2的平面内延伸。
应可以理解，第一开口411在垂直于第一轴A1的平面内延伸，有利于在第一透镜11安装于第一开口411的条件下，使得第一透镜11界定的第一光轴OA1更趋近平行于第一轴A1；同样的，第二开口421在垂直于第三轴A3的平面内延伸，有利于在第二透镜12安装于第二开口421的条件下，使得第二透镜12界定的第二光轴OA2更趋近平行于第二轴A2。
进一步的，如图41所示，第一开口411沿平行于第三轴A3的内径尺寸D1大于第二开口421沿平行于第一轴A1的内径尺寸D2，以使得第一透镜11沿平行于第三轴A3的尺寸大于第二透镜12沿平行于第一轴A1的尺寸；第一开口411沿平行于第二轴A2的内径尺寸D3大于第二开口421沿平行于第一轴A1的内径尺寸D2，以使得第一透镜11沿平行于第二轴A2的尺寸大于第二透镜12沿平行于第一轴A1的尺寸，进而使得第一透镜11具有较大的尺寸，有利于使更多的光线通过第一透镜11，以实现增大光圈的效果。
应可以理解，第一透镜11得以对光线进行收束，有利于减小光线射至第二透镜12上的区域面积，进而得以减小第二透镜12沿平行于第一轴A1的尺寸，以及有利于减小镜头模块101沿平行于第一轴A1的尺寸，得以降低摄像模组2的肩高h，有利于实现电子设备的轻薄化。
值得一提的是，在一些实施例中，第一透镜11和/或第二透镜12为非切边透镜时，第一开口411沿平行于第三轴A3的内径尺寸D1等于第一开口411沿平行于第二轴A2的内径尺寸D3。第二开口421沿平行于第一轴A1的内径尺寸D2等于第二开口421沿平行于第二轴A2的内径尺寸D4。
当然，在一些实施例中，第一透镜11和/或第二透镜12为切边透镜时，第一开口411沿平行于第三轴A3的内径尺寸D1小于第一开口411沿平行于第二轴A2的内径尺寸D3。第二开口421沿平行于第一轴A1的内径尺寸D2小于第二开口421沿平行于第二轴A2的内径尺寸D4。
在一些实施例中，如图37所示，第一安装部41与旋转载体30的安装面321之间界定第一空间21，第一透镜11的至少部分伸入第一空间21内，进而在沿平行于第一轴A1的方向上，使得第一安装部41、第一透镜11、反射元件13和旋转载体30的排布更为紧凑，有利于减小反射系统1的高度，进而减小摄像模组2的总高H；第二安装部42与旋转载体30的安装面321之间界定第二空间22，第二透镜12的至少部分伸入第二空间22内，进而在沿平行于第三轴A3的方向上，使得旋转载体30、反射元件13、第二安装部42和第一透镜11的排布更为紧凑，有利于减小反射系统1的长度，进而减小摄像模组2的长度，得以实现摄像模组2的小型化。
具体的，在第一透镜11的像侧面被实施为凸面时，第一透镜11的像侧面得以从第一开口411所在的平面朝反射元件13所在的方向凸出，以容置于第一空间21内。在第一透镜11的像侧面被实施为凹面时，第一透镜11的像侧面的边缘得以从第一开口411所在的平面朝反射元件13所在的方向延伸，以容置于第一空间21内。在第二透镜12的物侧面被实施为凹面时，第二透镜12的物侧面的边缘得以从第二开口421所在的平面朝反射元件13所在的方向延伸，以容置于第二空间22内。
在至少一个实施例中，反射元件13被实施为反射镜。应可以理解，相较于棱镜，本实施例中的反射镜具有更轻的重量和更小的尺寸，得以减小反射系统1在摄像模组2中的占用空间，有利于实现摄像模组2的小型化。此外，驱动反射镜所需的马达尺寸和动力也更小，并且有利于提高防抖的效果。
具体的，倘若使用棱镜作为反射元件13，在棱镜被安装于旋转载体30的安装面321的情况下，棱镜会占据较多的第一空间21和第二空间22，也就是说，棱镜的入射面会比较贴近第一安装部41，棱镜的出射面会比较贴近第二安装部42，进而导致第一透镜11难以延伸入第一空间21内，第二透镜12难以延伸入第二空间22内，不利于实现反射系统1的小型化。
而本实施例中，反射元件13被实施为反射镜，包括反射面131和固定面132，反射面131用于反射光线，固定面132用于和旋转载体30的安装面321相固定。应可以理解，反射镜得以占用较少的第一空间21和第二空间22，也就是说，反射镜的反射面131和第一安装部41之间具有较大的空间，反射面131和第二安装部42之间也具有较大的空间，以使得第一透镜11的物侧面得以容纳于第一安装部41和反射面131之间的第一空间21内，第二透镜12的像侧面得以容纳于反射面131和第二安装部42之间的第二空间22内，使得第一透镜11、反射镜和第二透镜12的排布更为紧凑，有利于减小反射系统1的整体体积，进而得以减小摄像模组2的总高H、肩高h和长度。
在一些实施例中，如图37和图40所示，反射镜的反射面131的面积大于固定面132的面积，应可以理解，固定面132的面积减小有利于减小旋转载体30的安装面321的面积，进而减小安装面321和反射镜在旋转载体30中的占用空间，以使旋转载体30具有更多的空间以安装反射系统1其他器件，例如第一驱动组件81、第二驱动组件82、感测组件90等，进而使得反射系统1的结构更为紧凑，有利于实现摄像模组2的小型化。进一步的，反射镜的反射面131积较大，有利于对进入反射系统1的光线尽可能多地进行反射，得以提高反射系统1的性能。
更进一步的，如图37和图40所示，反射镜还包括连接面133，连接面133用于连接反射面131和固定面132，以使得反射镜具有一定厚度，进而提高反射镜的结构强度。在至少一个实例中，反射镜的靠近第一透镜11一侧的连接面133沿平行于第一轴A1的方向延伸以连接反射面131和固定面132，靠近第二透镜12一侧的连接面133沿平行于第三轴A3的方向延伸，以连接反射面131和固定面132，并且连接面133得以与旋转载体30相固接，在保证反射镜的体积较小的情况下进一步提高反射镜和旋转载体30的连接强度和连接可靠性。
值得一提的是，反射元件13也可以被实施为棱镜，包括玻璃棱镜和塑料棱镜，本申请对此不作具体限制。
在一些实施例中，如图40和图41所示，安装架40还包括一对安装架侧部43，两个安装架侧部43沿平行于第二轴A2方向相对设置，安装架侧部43一体连接第一安装部41和第二安装部42，有利于提高第一安装部41和第二安装部42的连接强度，进而有利于提高安装架40的整体结构强度。进一步的，旋转载体30具有台阶部36，台阶部36与安装架侧部43相安装适配，使得安装架40固接于旋转载体30。应可以理解，通过台阶部36和安装架侧部43相配合得以起到限位的作用，有利于避免在生产安装和使用过程中，安装架40和旋转载体30产生相对移动，得以提高反射系统1的可靠性，并且有利于降低安装架40和旋转载体30的组装难度，提高反射系统1的生产效率。
在一些实施例中，如图42-图45所示，旋转载体30包括载体主体32、第一载体侧部33和第二载体侧部34。具体的，安装面321倾斜的设置于载体主体32，第一载体侧部33和第二载体侧部34沿第二轴A2的方向相对设置地位于载体主体32的两侧，使得第一载体侧部33、第二载体侧部34和安装面321之间形成容纳腔31，容纳腔31用于容置反射元件13。第一载体侧部33和第二载体侧部34分别设有一台阶部36，使得安装架40的一个安装架侧部43适于和第一载体侧部33相连，安装架40的另一个安装架侧部43适于和第二载体侧部34相连，进而安装架40得以架设于旋转载体30，使得第一透镜11和反射元件13沿第一轴A1相对设置，第二透镜12和反射元件13沿第三轴A3相对设置。
在一些实施例中，如图44所示，旋转载体30还包括第三载体侧部35，第三载体侧部35连接第一载体侧部33和第二载体侧部34，以提高旋转载体30的结构强度。并且第三载体侧部35位于远离反射系统1出射光线的一侧，进而得以在载体主体32、第一载体侧部33、第二载体侧部34和第三载体侧部35之间形成用于容纳反射元件13的容纳腔31。在至少一个具体实施例中，第三载体侧部35用于安装第一驱动组件81的至少部分，和/或第二驱动组件82的至少部分。

进一步的，如图45和图46所示，旋转载体30的第一凹部331面向第一支架侧部52的底面具有内凹的第一上槽3311，第二凹部341面向第二支架侧部53的底面具有内凹的第二上槽3411。旋转支架50的第一支架侧部52面向第一上槽3311的顶面具有内凹的第一下槽521，第二支架侧部53面向第二上槽3411的顶面具有内凹的第二下槽531。应可以理解，第一上槽3311和第一下槽521之间形成一运动空间，第二上槽3411和第二下槽531之间也形成一运动空间，得以使两个第一支撑元件71被分别设置于第一上槽3311和第一下槽521之间以及第二上槽3411和第二下槽531之间。其中，第一支撑元件71可以被实施为滚珠。也就是说，两个滚珠被分别地设置于第一载体侧部33和第一支架侧部52之间以及第二载体侧部34和第二支架侧部53之间。
值得一提的是，两个第一支撑元件71间隔地位于第二轴A2所在的直线上，以使被支撑于两个第一支撑元件71的旋转载体30得以相对旋转支架50绕第二轴A2旋转。
其中，沿着第二轴A2延伸的假想线穿过两个第一支撑元件71。进一步地，沿着第二轴A2延伸的假想线穿过两个第一支撑元件71和反射元件13。
在一些实施例中，如图48所示，固定组件60包括基底62和围绕基底62设置的第一基座侧部63、第二基座侧部64和第三基座侧部65，具体的，第一基座侧部63和第二基座侧部64沿第二轴A2的方向相对设置地位于基底62的两侧，第三基座侧部65连接第一基座侧部63和第二基座侧部64，并且第三基座侧部65位于远离反射系统1出射光线的一侧，使得固定组件60形成一用于容纳旋转支架50、活动载体20和反射组件10的安装空间61。
进一步的，如图47和图48所示，固定组件60的基底62和旋转支架50的支架主体51中的一者凸出地设有转轴件511，转轴件511沿平行于第一轴A1的方向延伸，并且转轴件511位于第一轴A1所在的直线上。其中，沿着第一轴A1延伸的假想线穿过转轴件511。进一步地，沿着第一轴A1延伸的假想线穿过转轴件511和反射元件13。基底62和支架主体51中的另一者设有定位槽624，定位槽624用于容置转轴件511，进而通过转轴件511得以使旋转支架50相对固定组件60绕第一轴A1旋转。更进一步的，基底62和支架主体51之间设有至少二个第二支撑元件72。其中，第二支撑元件72被实施为辅助滚珠，以用于支撑旋转支架50相对于固定组件60绕第一轴A1旋转。
在一些实施例中，沿平行于第一轴A1的方向，沿着第一轴A1延伸的假想线的投影与沿着第二轴A2延伸的假想线的投影不重叠。
应可以理解，为限制至少二辅助滚珠在固定组件60和旋转支架50之间的位置，固定组件60的基底62的顶面具有至少二辅助下槽621，旋转支架50的支架主体51的底面具有至少二辅助上槽512，至少二辅助上槽512和至少二辅助下槽621相对设置，以形成运动空间，使得至少二辅助滚珠被设置于旋转支架50的至少二辅助上槽512和固定组件60的至少二辅助下槽621之间。进一步的，辅助上槽512和辅助下槽621可以被实施为弧形槽或者直线形槽或者圆形槽，本申请对此不作具体限制。
值得一提的是，转轴件511可以被实施为主滚珠，也就是说，基底62和支架主体51之间设有一个主滚珠和至少两个辅助滚珠，以用于支撑旋转支架50，并使得旋转支架50相对固定组件60绕第一轴A1旋转。
在一些实施例中，如图43-图47所示，旋转载体30还包括第一凸部371和第二凸部372，第一凸部371和第二凸部372沿第二轴A2的方向相对设置，第一凸部371和第二凸部372位于载体主体32的底部并朝向固定组件60的基底62，并且第一凸部371和第二凸部372沿平行于第一轴A1的方向延伸。旋转支架50的支架主体51上开设有沿平行于第一轴A1的方向贯穿的避让孔513，避让孔513适于使第一凸部371和第二凸部372穿过，使得第一凸部371和第二凸部372与基底62沿第一轴A1的方向相对设置。
进一步的，第一凸部371和第二凸部372设置有磁吸磁石373，基底62上设置有与磁吸磁石373相对的磁轭622。应可以理解，通过磁吸磁石373和磁轭622的相互作用，得以向旋转载体30提供沿平行于第一轴A1朝向基底62的磁吸力，在磁吸力的作用下旋转支架50被支撑于旋转载体30和基底62之间。磁吸力还有利于使辅助滚珠夹持于旋转支架50和基底62之间，并且在摄像模组2受到外力的情况下，有利于减小活动载体20、旋转支架50和固定组件60相脱离的风险。
在一些实施例中，如图40和图42反射系统1还包括补强件623，补强件623嵌设于固定组件60的基底62，得以提高固定组件60的结构强度，有利于更好地支承反射系统1。在至少一个实施例中，磁轭622与补强件623一体弯折成型，磁轭622和补强件623在沿第一轴A1的方向上位于不同高度平面上。具体地，磁轭622所在平面与磁吸磁石373所在平面之间的距离小于补强件623所在平面与磁吸磁石373所在平面之间的距离。这样，一方面，磁轭622与补强件623的制造更加简单；另一方面，有利于增大磁轭622与磁吸磁石373之间的磁吸力，进而减小活动载体20与固定组件60相脱离的风险。
在至少一个实施例中，如图45所示，第一凸部371和第二凸部372间隔地位于第一凹部331和第二凹部341之间，使得旋转支架50和旋转载体30的结构更为紧凑。此外，第一凹部331和第二凹部341的间距相较于第一凸部371和第二凸部372的间距更大，也就是说，旋转支架50的第一支架侧部52和第一凹部331之间的支点，以及第二支架侧部53和第二凹部341之间的支点，这两个支点的间距较大，有利于旋转支架50更为稳定地支承活动载体20，减小活动载体20相对旋转支架50歪斜的风险。
在一些实施例中，如图42和图43所示，第一驱动组件81包括相对设置的至少一第一驱动线圈812和至少一第一驱动磁石811，第一驱动线圈812和第一驱动磁石811适于配合驱动活动载体20和旋转支架50绕第一轴A1旋转；第二驱动组件82包括相对设置的至少一第二驱动线圈822和至少一第二驱动磁石821，第二驱动线圈822和第二驱动磁石821适于配合驱动活动载体20绕第二轴A2旋转。
进一步的，反射系统1还包括驱动电路，驱动电路电连接于第一驱动线圈812和第二驱动线圈822并提供电流，使得第一驱动线圈812和第一驱动磁石811相互配合，以驱动旋转支架50绕第一轴A1旋转，以及使得第二驱动线圈822和第二驱动磁石821相互配合，以驱动活动载体20绕第二轴A2旋转。值得一提的是，驱动电路可以被实施为贴附于固定组件60的柔性线路板或者嵌入于固定组件60的导电金属嵌件。
在一些实施例中，如图42和图43所示，第一驱动磁石811和第二驱动磁石821设置于旋转载体30的第三载体侧部35的外表面，即第三载体侧部35上背离反射元件13的一侧的表面，第一驱动线圈812和第二驱动线圈822设置于固定组件60的第三基座侧部65的内表面，即第三基座侧部65上朝向反射元件13的一侧的表面。并且，第一驱动磁石811和第一驱动线圈812沿平行于第三轴A3的方向相对设置，进而在第一驱动线圈812通电后得以驱动旋转支架50和活动载体20绕第一轴A1旋转，即使得反射元件13绕第一轴A1旋转；第二驱动磁石821和第二驱动线圈822沿平行于第三轴A3的方向相对设置，进而在第二驱动线圈822通电后得以驱动活动载体20绕第二轴A2旋转，即使得反射元件13绕第二轴A2旋转。
也就是说，第一驱动组件81和第二驱动组件82同侧设置，即均被设置于活动载体20的背部。应可以理解，活动载体20的背部为沿第三轴A3第三载体侧部35背离反射元件13的一侧。第一支撑元件71、第二支撑元件72和转轴件511同侧设置，例如，均被设置于活动载体20的底部。应可以理解，活动载体20的底部为沿第一轴A1载体主体32背离反射元件13的一侧。更进一步地，第一驱动组件81和第二驱动组件82统称为驱动部，第一支撑元件71、第二支撑元件72和转轴件511统称为支撑部，其中，驱动部与支撑部异侧设置，驱动部被设置于活动载体20的背部，支撑部被设置于活动载体20的底部，以减小驱动部与支撑部之间的干涉，还有利于降低反射系统1沿平行于第一轴A1上侧方向的尺寸，进而有利于降低摄像模组2的总高H。

应可以理解，相较于第一驱动磁石811和第二驱动磁石821仅设置在第一载体侧部33和第二载体侧部34的其中一者，本实施例中，第一载体侧部33和第二载体侧部34均设有一组第一驱动磁石811和第二驱动磁石821，得以使活动载体20的受力更为均匀，有利于提高反射系统1驱动的可靠性。此外，相较于在第三载体侧部35设置第一驱动磁石811和第二驱动磁石821，本实施例中，在第一载体侧部33和第二载体侧部34设置第一驱动磁石811和第二驱动磁石821，有利于增长第一驱动组件81至第一轴A1的力臂，以及增长第二驱动组件82至第二轴A2的力臂，进而使反射系统1得以提供更大的防抖行程。
在另一些实施例中，旋转载体30的第一载体侧部33和第二载体侧部34各设有一个第一驱动磁石811，第三载体侧部35设有一个第二驱动磁石821；第一基座侧部63和第二基座侧部64各设有一个第一驱动线圈812，第三基座侧部65的内侧设有一个第二驱动线圈822。并且，第一驱动磁石811和第一驱动线圈812沿平行于第二轴A2的方向相对设置，进而在第一驱动线圈812通电后得以驱动旋转支架50和活动载体20绕第一轴A1旋转，即使得反射元件13绕第一轴A1旋转；第二驱动磁石821和第二驱动线圈822沿平行于第三轴A3的方向相对设置，进而在第二驱动线圈822通电后得以驱动活动载体20绕第二轴A2旋转，即使得反射元件13绕第二轴A2旋转。应可以理解，第一驱动磁石811和第二驱动磁石821设置于旋转载体30的不同侧部，有利于降低反射系统1沿平行于第一轴A1方向的尺寸，进而有利于降低摄像模组2的总高H，此外，第一驱动磁石811和第二驱动磁石821不同侧设置，有利于避免第一驱动组件81和第二驱动组件82之间的磁场产生干扰，进而得以提高反射系统1的驱动的可靠性。进一步的，如前文所述，第一支撑元件71设置于旋转载体30的第一凹部331、第二凹部341和旋转支架50的第一支架侧部52和第二支架侧部53之间，第二支撑元件72设置于旋转支架50的支架主体51和固定组件60的基底62之间。
在另一些实施例中，两个第一驱动磁石811沿平行于第二轴A2的方向间隔设置于旋转支架50的底面，即朝向固定组件60的基底62的表面，两个第一驱动线圈812沿平行于第二轴A2的方向间隔设置于基底62，第一驱动磁石811和第一驱动线圈812沿平行于第一轴A1的方向相对设置，进而在第一驱动线圈812通电后得以驱动旋转支架50和活动载体20绕第一轴A1旋转，即使得反射元件13绕第一轴A1旋转。至少一个第二驱动磁石821设置于第三载体侧部35的外表面，即第三载体侧部35上背离反射元件13的表面，至少一个第二驱动线圈822设置于第三基座侧部65，第二驱动磁石821和第二驱动线圈822沿平行于第三轴A3的方向相对设置，进而在第二驱动线圈822通电后得以驱动活动载体20绕第二轴A2旋转，即使得反射元件13绕第二轴A2旋转。应可以理解，第一驱动磁石811和第二驱动磁石821不同侧设置，有利于避免第一驱动组件81和第二驱动组件82之间的磁场产生干扰，进而得以提高反射系统1的驱动的可靠性。进一步的，如前文所述，第一支撑元件71设置于旋转载体30的第一凹部331、第二凹部341和旋转支架50的第一支架侧部52和第二支架侧部53的之间，第二支撑元件72设置于旋转支架50的支架主体51的固定组件60的基底62之间。
在一个具体实施例中，旋转载体30的第一凹部331面向第一支架侧部52的侧面具有内凹的第一转轴上槽，第二凹部341面向第一支架侧部52的侧面具有内凹的第二转轴上槽，旋转支架50的第一支架侧部52面向第一转轴上槽的侧面具有内凹的第一转轴下槽，第二支架侧部53面向第二转轴上槽的侧面具有内凹的第二转轴下槽。具体地，第一转轴上槽和第一转轴下槽沿平行于第三轴A3的方向相对设置，第二转轴上槽和第二转轴下槽沿平行于第三轴A3的方向相对设置，使得第一转轴上槽和第一转轴下槽之间形成一滚珠运动空间，第二转轴上槽和第二转轴下槽之间也形成一滚珠运动空间，进而两个转轴滚珠被分别设置于第一转轴上槽和第一转轴下槽之间以及第二转轴上槽和第二转轴下槽之间。值得一提的是，两个转轴滚珠间隔地位于第二轴A2所在的直线上，以使被支撑于两个转轴滚珠的旋转载体30得以相对旋转支架50绕第二轴A2旋转。
在另一些实施例中，旋转支架50设置于旋转载体30的第三载体侧部35和固定组件60的第三基座侧部65之间，应可以理解，通过设置在旋转载体30中的磁吸磁石373和设置在固定组件60的磁轭622之间的吸引力，得以使旋转载体30和旋转支架50附接于固定组件60。进一步的，旋转载体30的第一载体侧部33和第二载体侧部34各设有一第一驱动磁石811，第一基座侧部63和第二基座侧部64各设有一第一驱动线圈812，第一驱动磁石811和第一驱动线圈812沿平行于第二轴A2的方向相对设置，进而在第一驱动线圈812通电后得以驱动旋转支架50和活动载体20绕第一轴A1旋转，即使得反射元件13绕第一轴A1旋转。旋转支架50的外表面，即远离旋转载体30的表面设有第二驱动磁石821，固定组件60的第三基座侧部65的内表面设有一第二驱动线圈822，第二驱动磁石821和第二驱动线圈822沿平行于第三轴A3的方向相对设置，进而在第二驱动线圈822通电后得以驱动活动载体20绕第二轴A2旋转，即使得反射元件13绕第二轴A2旋转。应可以理解，第一驱动磁石811和第二驱动磁石821设置于旋转载体30的各个侧部，有利于降低反射系统1沿平行于第一轴A1方向的尺寸，进而有利于降低摄像模组2的总高H，此外，第一驱动磁石811和第二驱动磁石821不同侧设置，有利于避免第一驱动组件81和第二驱动组件82之间的磁场产生干扰，进而得以提高反射系统1的驱动的可靠性。进一步的，一对沿第一轴A1方向对准的转轴滚珠被夹持于旋转载体30的第三载体侧部35和旋转支架50之间，以支撑旋转载体30相对旋转支架50绕第一轴A1旋转；一对沿第二轴A2方向对准的转轴滚珠被夹持于旋转支架50和固定组件60的第三基座侧部65之间，以支撑旋转支架50相对固定组件60绕第二轴A2旋转。
在另一些实施例中，旋转支架50设置于旋转载体30的第三载体侧部35和固定组件60的第三基座侧部65之间，应可以理解，通过设置在旋转载体30中的磁吸磁石373和设置在固定组件60的磁轭622之间的吸引力，得以使旋转载体30和旋转支架50附接于固定组件60。进一步的，旋转载体30的第一载体侧部33和第二载体侧部34各设有一第一驱动磁石811，第一基座侧部63的内侧和第二基座侧部64各设有一第一驱动线圈812，第一驱动磁石811和第一驱动线圈812沿平行于第二轴A2的方向相对设置，进而在第一驱动线圈812通电后得以驱动旋转支架50和活动载体20绕第一轴A1旋转，即使得反射元件13绕第一轴A1旋转。旋转载体30的载体主体32的底面，即朝向基座的基底62的表面设有第二驱动磁石821，基底62上设有第二驱动线圈822，第二驱动磁石821和第二驱动线圈822沿平行于第一轴A1的方向相对设置，进而在第二驱动线圈822通电后得以驱动活动载体20绕第二轴A2旋转，即使得反射元件13绕第二轴A2旋转。应可以理解，第一驱动磁石811和第二驱动磁石821不同侧设置，有利于避免第一驱动组件81和第二驱动组件82之间的磁场产生干扰，进而得以提高反射系统1的驱动的可靠性。进一步的，一对沿第一轴A1方向对准的转轴滚珠被夹持于旋转载体30的第三载体侧部35和旋转支架50之间，以支撑旋转载体30相对旋转支架50绕第一轴A1旋转；一对沿第二轴A2方向对准的转轴滚珠被夹持于旋转支架50和固定组件60的第三基座侧部65之间，以支撑旋转支架50相对固定组件60绕第二轴A2旋转。
在一些实施例中，如图42-图45，以及图49-图50所示，反射系统1还包括感测组件90，感测组件90包括设置于固定组件60的第一感测元件92和第二感测元件94，以及设置于活动载体20的第一感测磁石91和第二感测磁石93，并且，第一感测元件92和第一感测磁石91沿平行于第二轴A2的方向相对设置，使得第一感测元件92获取第一感测磁石91的第一磁场信息，以感测活动载体20绕第一轴A1旋转的行程，第二感测元件94和第二感测磁石93沿平行于第三轴A3的方向相对设置，使得第二感测元件94获取第二感测磁石93的第二磁场信息，以感测活动载体20绕第二轴A2旋转的行程。
应可以理解，通常情况下活动载体20同时存在绕第一轴A1旋转和绕第二轴A2旋转，因此，为提高第一感测磁石91和第一感测元件92对活动载体20绕第一轴A1旋转行程的感测准确性，需要降低活动载体20绕第二轴A2旋转产生的对第一感测磁石91和第一感测元件92的影响；同样的，为提高第二感测磁石93和第二感测元件94对活动载体20绕第二轴A2旋转行程的感测准确性，需要降低活动载体20绕第一轴A1旋转产生的对第二感测磁石93和第二感测元件94的影响。
在一些实施例中，第一感测磁石91包括在平行于第二轴A2的方向上间隔设置的第一旋转感测磁石911和第二旋转感测磁石912，第一感测元件92包括第一旋转感测元件921和第二旋转感测元件922，并且，第一旋转感测元件921和第一旋转感测磁石911沿平行于第二轴A2的方向相对设置，第二旋转感测元件922和第二旋转感测磁石912沿平行于第二轴A2的方向相对设置，第一旋转感测元件921获取第一旋转感测磁石911的第一旋转磁场信息T1，第二旋转感测元件922获取第二旋转感测磁石912的第二旋转磁场信息T2，得以通过第一旋转磁场信息T1与第二旋转磁场信息T2计算获得活动载体20绕第一轴A1旋转的行程。
在一个具体实施例中，第一旋转感测磁石911设置于旋转载体30的第一载体侧部33，第二旋转感测磁石912设置于第二载体侧部34，并且第一旋转感测磁石911和第二旋转感测磁石912沿平行于第二轴A2的方向相对设置。第一旋转感测元件921设置于固定组件60的第一基座侧部63，得以与第一旋转感测元件921相对设置，第二旋转感测元件922设置于第二基座侧部64，得以与第二旋转感测元件922相对设置。
应可以理解，由于第一载体侧部33和第二载体侧部34的可用空间较小，因而对第一旋转感测磁石911和第二旋转感测磁石912的体积造成限制，并且在活动载体20运动的过程中，第一旋转感测元件921和第二感测元件94相对第一旋转感测磁石911和第二旋转感测磁石912的位移较大。这使得，在活动载体20绕第一轴A1旋转运动的过程中存在绕第二轴A2旋转的运动时，第一旋转感测元件921与第一旋转感测磁石911的相对边之间存在一定的倾斜角度，第二旋转感测元件922与第二旋转感测磁石912的相对边之间存在一定的倾斜角度，换言之，第一旋转感测元件921的中线与第一旋转感测磁石911的两个磁极的中线不平行，第二旋转感测元件922的中线与第二旋转感测磁石912的两个磁极的中线不平行，导致第一旋转感测元件921和第二旋转感测元件922的感测结果易于受到活动载体20绕第二轴A2旋转的影响。
倘若仅在第一载体侧部33或第二载体侧部34设置一第一感测磁石91，由于第一感测磁石91和第一感测元件92的感测结果易于受到活动载体20绕第二轴A2旋转的影响，将导致第一感测元件92的感测精确度下降，不利于反射系统1的控制。而本申请中，通过在旋转载体30的第一载体侧部33设置第一旋转感测磁石911，在第二载体侧部34设置第二旋转感测磁石912，进而通过第一旋转感测磁石911和第一旋转感测元件921的配合，以及第二旋转感测磁石912和第二旋转感测元件922的配合，得以减小感测活动载体20在绕第一轴A1旋转运动的过程中受到绕第二轴A2旋转的运动造成的影响。
具体的，第一旋转感测元件921获取第一旋转感测磁石911的第一旋转磁场信息T1，第二旋转感测元件922获取第二旋转感测磁石912的第二旋转磁场信息T2，得以计算活动载体20绕第一轴A1旋转的中心值Tm，Tm＝(T1+T2)/2；进一步的，第一旋转感测元件921获取的关于活动载体20绕第一轴A1旋转的行程信息为T1-Tm，第二旋转感测元件922获取的关于活动载体20绕第一轴A1旋转的行程信息为T2-Tm；更进一步的，活动载体20绕第一轴A1旋转的行程信息为(T1-Tm)+(T2-Tm)，即第一旋转感测元件921和第二旋转感测元件922获取的活动载体20绕第一轴A1旋转的行程信息之和。
应可以理解，在活动载体20同时存在绕第一轴A1旋转和绕第二轴A2旋转时，第一旋转磁场信息T1和第二旋转磁场信息T2中将包含有绕第二轴A2旋转的行程信息，并且第一旋转磁场信息T1中包含绕第二轴A2旋转的行程信息与第二旋转磁场信息T2中包含的绕第二轴A2旋转的行程信息相反，进而通过计算(T1+T2)/2得以抵消绕第二轴A2旋转的行程信息，以使得Tm中不再存在绕第二轴A2旋转的行程信息的干扰，以避免活动载体20绕第二轴A2的旋转对第一旋转感测元件921和第二旋转感测元件922的感测结果产生干扰，有利于提高第一旋转感测元件921和第二旋转感测元件922的感测结果的精确性，实现对反射系统1更好的闭环控制。
值得一提的是，前文所述的(T1+T2)、(T1-Tm)、(T2-Tm)以及(T1-Tm)+(T2-Tm)并非简单直接相加减，而是包含复杂的算法处理过程的。具体的，计算转动角度的过程可能包括但不限于：1.对磁场信息的数据预处理步骤，例如将第一旋转感测元件921和第二旋转感测元件922的输出信号转化为数字信号，对信号进行滤波和放大等处理；2.对数据进行中心化处理或者零均值化处理，或者进行平移处理；3.根据反射系统1所处的外界环境对检测结果进行校准；4.在计算过程中调试优化算法。
在一些实施例中，第一旋转感测磁石911与第二旋转感测磁石912相对于第三轴A3对称设置，其中，第一旋转感测磁石911和第二旋转感测磁石912均为多极磁石，具有沿平行于第二轴A2方向和沿平行于第三轴A3方向的N极区和S极区，并且，第一旋转感测磁石911和第二旋转感测磁石912的N极区和S极区相对第三轴A3对称分布。第一旋转感测元件921与第一旋转感测磁石911的N极区和S极区中的至少一者沿平行于第二轴A2的方向相对，以感测第一旋转磁场信息T1；第二旋转感测元件922与第二旋转感测磁石912的N极区和S极区中的至少一者沿平行于第二轴A2的方向相对，以感测第二旋转磁场信息T2。并且，如图51所示，在第一旋转感测元件921与N极区和S极区中的一者相对的条件下，第二旋转感测元件922与N极区和S极区中的另一者相对，也就是说，第一旋转感测元件921和第二旋转感测元件922分别与不同的磁极沿平行于第二轴A2的方向相对，进而在活动载体20同时存在绕第一轴A1旋转和绕第二轴A2旋转时，第一旋转磁场信息T1中包含绕第二轴A2旋转的行程信息与第二旋转磁场信息T2中包含的绕第二轴A2旋转的行程信息相反。
进一步的，在活动载体20绕第一轴A1的旋转运动中存在绕第二轴A2的旋转运动时，第一旋转感测元件921和第二旋转感测元件922所获取的第一旋转磁场信息T1中包含的绕第二轴A2旋转的行程信息与第二旋转磁场信息T2中包含的绕第二轴A2旋转的行程信息相反。
例如，在活动载体20绕第一轴A1旋转运动时，如果第一旋转感测元件921所面对的第一旋转感测磁石911的N极区的面积增大、S极区的面积减小，则第二旋转感测元件922所面对的第二旋转感测磁石912的N极区的面积减小、S极区的面积增大。反之，如果第一旋转感测元件921所面对的第一旋转感测磁石911的S极区的面积增大、N极区的面积减小，则第二旋转感测元件922所面对的第二旋转感测磁石912的S极区的面积减小、N极区的面积增大。也就是说，在活动载体20绕第一轴A1旋转运动时，第一旋转感测元件921相对第一旋转感测磁石911，和第二旋转感测元件922相对第二旋转感测磁石912，朝不同的磁极方向移动。
应可以理解，当活动载体20绕第一轴A1的旋转运动中不存在绕第二轴A2的旋转运动的干扰时，第一旋转感测元件921的沿第一轴A1方向的中线与第一旋转感测磁石911的两个磁极的中线平行，第二旋转感测元件922的沿第一轴A1方向的中线与第二旋转感测磁石912的两个磁极的中线平行，以提高第一旋转感测元件921和第二旋转感测元件922的感测精度。
应可以理解，第一旋转感测磁石911和第二旋转感测磁石912为多极磁石，以提供更加均匀和稳定的磁场分布。由于多极磁石的充磁过程使得第一旋转感测磁石911和第二感测磁石93均包括N极区、S极区，及位于N极区与S极区之间的中性区，当活动载体20绕第一轴A1的旋转运动中不存在绕第二轴A2的旋转运动的干扰时，第一旋转感测磁石911的中性区与第一旋转感测元件921的沿第一轴A1方向的中线平行，第二旋转感测磁石912的中性区与第二旋转感测元件922的沿第一轴A1方向的中线平行，进而得以提高第一旋转感测元件921和第二旋转感测元件922的感测精度。
在一些实施例中，如图42所示，如前文所述，两个第一驱动磁石811沿平行于第二轴A2的方向间隔设置于第三载体侧部35，一个第二驱动磁石821位于两个第一驱动磁石811之间。进一步的，第二感测元件94设置于固定组件60的第三基座侧部65，使得第二感测元件94与第二驱动磁石821沿平行于第三轴A3的方向相对设置，使得所述第二感测元件94获取所述第二驱动磁石821的第二磁场信息，以感测所述活动载体20绕第二轴A2旋转的行程。也就是说，第二驱动磁石821同时用作第二感测磁石93，以减少反射系统1的零件数量，降低反射系统1的生产成本。应可以理解，第二驱动磁石821的磁极沿平行于第一轴A1的方向分布，在活动载体20绕第二轴A2旋转的过程中，第二驱动磁石821相对第二感测元件94运动，第二感测元件94得以感测第二驱动磁石821的磁场信息的变化，进而感测活动载体20绕第二轴A2旋转的行程。
进一步的，第二驱动磁石821的磁极沿平行于第一轴A1的方向具有较长的尺寸，进而在活动载体20绕第二轴A2旋转的过程中，第二感测元件94得以始终与第二驱动磁石821保持相对设置，使得第二感测元件94始终位于第二驱动磁石821的磁场区域内，并且第二感测元件94与第二驱动磁石821的相对位置受活动载体20绕第一轴A1旋转的影响较小，有利于提高第二感测元件94的感测结果的精确性，实现对反射系统1更好的闭环控制。
值得一提的是，第二感测磁石93也可以另外设置于旋转载体30，例如，第二感测磁石93以独立于第二驱动磁石821的方式被设置于第三载体侧部35，并且，第二感测元件94与第二感测磁石93沿平行于第三轴A3的方向相对设置，使得所述第二感测元件94获取所述第二驱动磁石821的第二磁场信息，以感测所述活动载体20绕第二轴A2旋转的行程。应可以理解，第二感测磁石93和第二驱动磁石821分别设置，得以减小第二驱动磁石821和第二驱动线圈822之间的磁场对第二感测磁石93的磁场的影响，有利于提高第二感测元件94的感测精度。
其中，第二感测元件94可以被设置于第二驱动线圈822内，以使得反射系统1的结构更为紧凑；第二感测元件94也可以被设置于第二驱动线圈822外，以减小第二驱动线圈822产生的磁场对第二感测元件94的影响，有利于提高第二感测元件94的感测精度，本申请对此不作具体限制。
应可以理解，第一旋转感测磁石911、第二旋转感测磁石912和第二感测磁石93分别设置于旋转载体30的不同侧，有利于避免各个感测磁石的磁场相互干扰，有利于提高感测组件90的感测精度，进而得以提高反射系统1的控制的精准性和可靠性。
在一些实施例中，活动载体20的旋转中心与活动载体20的重心趋近重合。值得一提的是，活动载体20的重心是指反射组件10以及第一驱动磁石811、第二驱动磁石821、第一感测磁石91和第二感测磁石93安装于活动载体20后整体的重心。应可以理解，倘若重心与旋转中心的距离较大，由于重力的影响会形成扭矩，进而在第一驱动组件81的第二驱动组件82驱动活动载体20绕第一轴A1和/或绕第二轴A2旋转时，可能需要克服因重力产生的扭矩，造成驱动所需的电流增大。并且在反射系统1因外力晃动时，因重力产生的扭矩会驱使活动载体20和旋转支架50相对固定组件60活动，进而可能发出异响，并且可能会缩短反射系统1的使用寿命。而本实施例中，活动载体20的旋转中心与活动载体20的重心趋近重合，有利于使活动载体20在不受驱动力时保持稳定，在受到第一驱动组件81和第二驱动组件82的驱动力时快速响应，有利于提高反射系统1的可靠性。
进一步的，活动载体20的旋转中心与反射元件13的中心重合，使得反射元件13被驱动绕第一轴A1和/或绕第二轴A2旋转的过程中，反射元件13得以反射所有进入反射系统1的光线，进而减小摄像模组2的成像像面的裁切角，有利于提高成像效果。
更进一步的，如图36和图38所示，第一轴A1与第一透镜11界定的第一光轴OA1之间的距离小于0.5mm，第三轴A3与第二透镜12界定的第二光轴OA2之间的距离小于0.5mm。优选的，第一轴A1与第一光轴OA1重合，第三轴A3与第二光轴OA2重合，得以进一步提高摄像模组2的成像效果。
一种摄像模组2，如图36-图38所示，包括：如上的反射系统1；镜头模块101，镜头模块101被保持于反射系统1的光反射路径上；以及成像模块105，成像模块105接收镜头模块101出射的光线进行成像；基座106，基座106具有容置腔1063，反射系统1和镜头模块101被设置于容置腔1063内，反射系统1的固定组件60一体或分体设置于基座106；壳体107，壳体107罩设于基座106。
应可以理解，如前文所述，通过反射系统1的第一透镜11得以对光线进行收束，有利于减小光线射至第二透镜12上的区域面积，进而得以减小第二透镜12沿平行于第一轴A1的尺寸。进一步的，镜头模块101中的各个光学透镜沿平行于第一轴A1方向的尺寸与第二透镜12沿平行于第一轴A1方向的尺寸较为接近，因而在光线被第一透镜11收束的条件下，也有利于减小镜头模块101中的各个光学透镜沿平行于第一轴A1方向的光学有效径，进而得以降低摄像模组2的肩高h，有利于实现摄像模组2的小型化。
在一些实施例中，如图36-图38所示，壳体107包括主壳体部1072和副壳体部1073，副壳体部1073沿第一轴A1凸出地位于主壳体部1072上设置反射系统1的一端，主壳体部1072界定主腔室10721，主腔室10721用于容纳基座106，副壳体部1073界定副腔室10731，副腔室10731与主腔室10721连通，反射系统1的至少部分延伸入副腔室10731；主壳体部1072的上内表面与基座106的下内表面的间距记为H1，副壳体部1073沿第三轴A3相对设置的两个内表面的间距记为H2，满足：H2＞H1。
应可以理解，主壳体部1072的上内表面与基座106的下内表面的间距H1较小，得以在保证镜头模块101容纳于主腔室10721的基础上，减小摄像模组2沿平行于第一轴A1方向的尺寸。进一步的，副壳体部1073沿第三轴A3相对设置的两个内表面的间距H2较大，可以将尺寸较大的第一透镜11容置于副腔室10731中，以起到增大光圈的效果。
在一些实施例中，如图36和图37，所示，镜头模块101包括多个透镜，镜头模块101用于将光线成像在成像模块105的成像面上。具体的，镜头模块101包括第一镜头组1011和第二镜头组1012，第一镜头组1011与第二镜头组1012沿光轴方向依次设置。
在一个具体实施例中，第一镜头组1011为固定镜头组，第二镜头组1012为对焦镜头组，也就是说，第一镜头组1011被固定于基座106，第二镜头组1012被承载于镜头载体102，通过对焦驱动组件104得以驱动镜头载体102承载第二镜头组1012沿平行于第三轴A3方向运动，进而通过调节第一镜头组1011和第二镜头组1012的相对位置得以实现潜望式摄像模组2的光学对焦功能，此外，第二镜头组1012和成像模块105的成像面的相对位置也得以进行调整，以切换摄像模组2的成像模式。
应可以理解，镜头模块101还可以包括第三镜头组和/或第四镜头组，第三镜头组和/或第四镜头组可以沿平行于第三轴A3方向运动，以实现光学变焦功能，本申请对此不作具体限制。
在一些实施例中，如图52和图53所示，对焦驱动组件104包括对焦线圈1041和对焦磁石1042。具体的，对焦线圈1041设置于镜头载体102、基座106中的一者，对焦磁石1042设置于镜头载体102、基座106中的另一者，并且对焦线圈1041和对焦磁石1042沿平行于第一轴A1的方向相对设置，或对焦线圈1041和对焦磁石1042沿平行于第二轴A2的方向相对设置，进而对焦线圈1041和对焦磁石1042的配合得以驱动镜头载体102和第二镜头组1012沿平行于第三轴A3方向运动。
在一个具体实施例中，如图52和图53所示，镜头载体102沿平行于第二轴A2方向的一侧设置有一对对焦磁石1042和对焦线圈1041，以使镜头模块101的结构更为紧凑，有利于进一步实现摄像模组2的小型化。在另一个具体实施例中，镜头载体102沿平行于第二轴A2方向相对的两侧各设置有一对对焦磁石1042和对焦线圈1041，以向镜头载体102和第二镜头组1012提供更大的驱动力，提高摄像模组2的对焦操作的稳定性和可靠性。
在一些实施例中，镜头载体102的底面和基座106之间设有支承件103，以支承镜头载体102相对基座106沿平行于第三轴A3方向运动，有利于减小镜头载体102和基座106之间的摩擦阻力，提高镜头载体102和基座106之间相对运动的可靠性。可以理解是，支承件103可以被实施为导杆或者滚珠，本申请对此不作具体限制。
在一个具体实施例中，如图53所示，镜头载体102的底面的一侧设有导槽1021，导槽1021沿平行于第三轴A3的方向延伸，基座106上设有导杆1031，导杆1031适配安装于导槽1021，进而通过导槽1021和导杆1031的配合得以引导镜头载体102相对基座106沿平行于第三轴A3的方向移动。进一步的，镜头载体102的底面的另一侧设有两个镜头滚珠1032，两个镜头滚珠1032沿平行于第三轴A3的方向间隔设置，并且，其中一个镜头滚珠1032紧配于镜头载体102和基座106之间，得以支承镜头载体102，另一个镜头滚珠1032松配于镜头载体102和基座106之间，得以在镜头模块101受到外力时辅助支承镜头载体102。
应可以理解，倘若仅设置一个镜头滚珠1032，则在摄像模组2跌落时，镜头载体102倾斜后的压力集中于一个镜头滚珠1032，进而对镜头滚珠1032造成冲击，容易导致镜头载体102、镜头滚珠1032或基座106受到损坏，例如产生凹坑、裂纹等。而本申请的实施例中，两个镜头滚珠1032沿平行于第三轴A3的方向间隔设置，并且，其中一个镜头滚珠1032紧配，另一个镜头滚珠1032松配，进而在通过一个镜头滚珠1032和导杆1031配合以支承镜头载体102顺滑移动的基础上，得以在摄像模组2跌落时通过两个镜头滚珠1032对镜头载体102提供支撑，也就是说，两个镜头滚珠1032得以分担冲击力，进而降低镜头载体102、镜头滚珠1032或基座106受到损坏的风险。
值得一提的是，为限制至少二镜头滚珠1032在镜头载体102和基座106之间的位置，镜头载体102的底面开设有滚珠槽1022，以容置镜头滚珠1032。应可以理解，可以通过调节滚珠槽1022的深度，使得两个滚珠槽1022的深度不一致，以实现一个镜头滚珠1032紧配于镜头载体102和基座106之间，另一个镜头滚珠1032松配于镜头载体102和基座106之间，进而得以使两个镜头滚珠1032的尺寸一致，有利于减少零件种类，降低装配难度；也可以通过一个镜头滚珠1032被实施为尺寸较大的滚珠，另一个镜头滚珠1032被实施为尺寸较小的滚珠，而两个滚珠槽1022的深度一致，得以在实现一个镜头滚珠1032紧配于镜头载体102和基座106之间，另一个镜头滚珠1032松配于镜头载体102和基座106之间的基础上，降低镜头载体102的加工难度。
值得一提的是，镜头模块101的驱动组件还可以被实施为SMA马达(Small Motor Actuator)、压电马达等，本申请对此不做限制。

应可以理解，旋转支架50绕第一轴A1旋转时，旋转支架50的四个平行于第一轴A1延伸的棱边处容易与基座106的侧壁产生碰撞，因而第一缓冲部2011设置于旋转支架50的四个平行于第一轴A1延伸的棱边处，以避免棱边与基座106相撞。此外，第一缓冲部2011也可以设置于旋转支架50的沿平行于第二轴A2方向相对设置的侧壁，和/或基座106的沿平行于第二轴A2方向相对设置的侧壁，以避免旋转支架50与基座106相撞。

应可以理解，活动载体20绕第二轴A2旋转时，活动载体20的其中两个平行于第二轴A2延伸的棱边处容易与旋转支架50的顶面产生碰撞，因而第二缓冲部2012设置于活动载体20的四个平行于第二轴A2延伸的棱边处，以避免棱边与旋转支架50的顶面相撞。此外，第二缓冲部2012也可以设置于旋转支架50的顶面，即旋转支架50上沿平行于第一轴A1的方向和活动载体20相对的表面；或者活动载体20的底面，即活动载体20上沿平行于第一轴A1的方向和旋转支架50相对的表面，以避免活动载体20与旋转支架50相撞。
