背景技术Background technique

目前，在摄像头模组中，有一些后焦较大的镜片组，由于镜片组的后焦较长，则摄像在光轴方向的尺寸会比较大。同时在实现自动对焦时，对焦行程长，模组沿着镜片组光轴方向的尺寸要预留对焦的空间，使得模组的外形结构在镜片组光轴方向较大。At present, in the camera module, there are some lens groups with a larger back focus. Since the back focus of the lens group is longer, the size of the camera in the optical axis direction will be larger. At the same time, when auto-focusing is realized, the focusing stroke is long, and the size of the module along the optical axis of the lens group should reserve space for focusing, so that the shape and structure of the module are larger in the optical axis direction of the lens group.

具体实施方式Detailed ways

下面详细描述本公开的实施例，参考附图描述的实施例是示例性的，下面详细描述本公开的实施例。The embodiments of the present disclosure are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary, and the embodiments of the present disclosure are described in detail below.

下面参考图1描述根据本公开实施例的摄像头模组1，该摄像头模组1可以应用在电子设备中，电子设备还可以进一步地包括：本体，摄像头模组1设置于本体内。The following describes a camera module 1 according to an embodiment of the present disclosure with reference to FIG. 1. The camera module 1 can be applied to an electronic device, and the electronic device may further include a body in which the camera module 1 is disposed.

如图1所示，根据本公开实施例的摄像头模组1包括：镜片组10、光路改变组件20和图像传感器30。从物侧物体反射的光线经过镜片组10后,光路改变组件20将出射的光线传递给图像传感器30，以供图像传感器30处理。As shown in FIG. 1, the camera module 1 according to the embodiment of the present disclosure includes: a lens group 10, an optical path changing component 20 and an image sensor 30. After the light reflected from the object-side object passes through the lens group 10, the light path changing component 20 transmits the emitted light to the image sensor 30 for processing by the image sensor 30.

具体地，如图1所示，光路改变组件20具有多个光学面，至少一个光学面位于镜片组10的像侧。图像传感器30设置于最后的光学面的出射侧。也就是说，外部光线从物侧进入镜片组10之后通过光路改变组件20的第一光学面210反射，然后传至光路改变组件20的最后的光学面进行反射，再传至图像传感器30，如此设置的光路改变组件20可以通过改变光线传递路线，可以有效实现光线的传递，以及可以减小镜片组10的轴向长度，可以减小镜片组10的后焦长度，从而可以减小摄像头模组1沿光轴方向的长度，可以实现摄像头模组1光轴方向小型化设计的目标。Specifically, as shown in FIG. 1, the optical path changing component 20 has a plurality of optical surfaces, and at least one optical surface is located on the image side of the lens group 10. The image sensor 30 is provided on the exit side of the last optical surface. That is, the external light enters the lens group 10 from the object side and is reflected by the first optical surface 210 of the optical path changing component 20, and then transmitted to the last optical surface of the optical path changing component 20 for reflection, and then transmitted to the image sensor 30. The set optical path changing component 20 can effectively realize the transmission of light by changing the light transmission route, and can reduce the axial length of the lens group 10, and can reduce the back focus length of the lens group 10, thereby reducing the camera module 1 The length along the optical axis can achieve the goal of miniaturization of the camera module 1 in the optical axis direction.

而且，在此基础上，摄像头模组1还包括：驱动组件，驱动组件设置在光路改变组件20，以驱动光路改变组件20沿光轴方向移动。将多个光学面看成一个整体，通过驱动组件驱动光路改变组件20沿着镜片组10光轴方向进行移动。这样驱动组件通过驱动光路改变组件20的方式来实现自动对焦，避免了移动质量较大的镜片组10，如此，该摄像头模组1不仅可以减小沿镜片组10光轴方向的尺寸，也可以实现更快的自动对焦功能。Moreover, on this basis, the camera module 1 further includes a driving component, which is arranged in the optical path changing component 20 to drive the optical path changing component 20 to move along the optical axis direction. Considering the multiple optical surfaces as a whole, the optical path changing component 20 is driven to move along the optical axis direction of the lens group 10 through the driving component. In this way, the driving component realizes auto-focusing by driving the optical path changing component 20, which avoids moving the lens group 10 with a larger mass. In this way, the camera module 1 can not only reduce the size along the optical axis of the lens group 10, but also Achieve faster autofocus function.

由此，区别于传统驱动镜片组的方式，本公开的镜片组10可以固定不动，而光路改变组件20在驱动组件的驱动下沿图像传感器30成像的光轴方向进行移动，驱动组件带动光路改变组件20移动来实现光程的距离变化，例如，在光路改变组件20中的光学面个数为两个时，光路改变组件20移动1X的距离，光程可以相应地增加2X，比传统的沿着镜片组光轴直线式对焦的方式节省了一倍的移动距离。Therefore, different from the traditional way of driving the lens group, the lens group 10 of the present disclosure can be fixed, and the optical path changing component 20 moves along the optical axis of the image sensor 30 under the driving of the driving component, and the driving component drives the optical path. The movement of the component 20 is changed to realize the distance change of the optical path. For example, when the number of optical surfaces in the optical path changing component 20 is two, the optical path changing component 20 moves a distance of 1X, and the optical path can be increased by 2X accordingly, which is higher than the traditional one. The linear focusing method along the optical axis of the lens group saves twice the moving distance.

另外，光路改变组件20中光学面个数为两个以上时，当光路改变组件20移动一定的距离，光程会增加相应光学面个数乘以光路改变组件20移动的距离。In addition, when the number of optical surfaces in the optical path changing component 20 is more than two, when the optical path changing component 20 moves a certain distance, the optical path will increase the corresponding number of optical surfaces multiplied by the moving distance of the optical path changing component 20.

如此，通过本公开的方式，可以缩短光路改变组件20移动距离，可以进一步地缩短对焦时间，从而提高摄像头模组1的性能，而且此种方式也可以避免移动质量较大的镜片组10，可以提高摄像头模组1的可靠性。由此，摄像头模组1同时通过两个光学面改变光路，移动光路改变组件20的方式来实现自动对焦，避免了移动质量较大的镜片组10，并且光路改变组件20对后焦的光路折叠作用，可以缩减摄像头模组1的体积，因此，该摄像头模组1不仅可以减小沿镜片组10光轴方向的长度，实现更快的自动对焦功能，也可以减小自身体积，在使用时会更加轻便。In this way, through the method of the present disclosure, the moving distance of the optical path changing assembly 20 can be shortened, the focusing time can be further shortened, thereby improving the performance of the camera module 1, and this method can also avoid moving the lens group 10 with a larger mass. Improve the reliability of the camera module 1. As a result, the camera module 1 simultaneously changes the optical path through two optical surfaces and moves the optical path changing component 20 to achieve autofocus, avoiding moving the lens group 10 with a larger mass, and the optical path changing component 20 folds the optical path of the back focus. It can reduce the volume of the camera module 1. Therefore, the camera module 1 can not only reduce the length along the optical axis of the lens group 10 to achieve faster autofocus function, but also reduce its own volume. Will be more portable.

如图1所示，光路改变组件20包括多个光学改变元件，每个光学改变元件至少具有一个光学面。这样通过多个光学改变元件的光学面改变光路，可以减小沿着镜片组10光轴方向的模组长度。而且，通过设置多个光学改变元件，可以增加光路改变组件20的布置灵活性，可以提高光路改变组件20的布置可靠性。As shown in FIG. 1, the optical path changing assembly 20 includes a plurality of optical changing elements, and each optical changing element has at least one optical surface. In this way, the optical path is changed by the optical surfaces of the multiple optical changing elements, and the length of the module along the optical axis of the lens group 10 can be reduced. Moreover, by arranging a plurality of optical changing elements, the flexibility of the arrangement of the optical path changing assembly 20 can be increased, and the reliability of the arrangement of the optical path changing assembly 20 can be improved.

根据本公开的一个可选实施例，多个所述光学改变元件均为棱镜。采用棱镜的方式可以使得光路改变组件20结构简单，易于布置，而且此种结构的光路改变组件20可以方便驱动组件驱动。According to an optional embodiment of the present disclosure, a plurality of the optical changing elements are all prisms. The use of a prism can make the light path changing component 20 simple in structure and easy to arrange, and the light path changing component 20 of this structure can facilitate the driving of the component.

下面结合附图详细描述一种光学改变元件为棱镜的具体实施例。A specific embodiment in which the optical changing element is a prism will be described in detail below with reference to the accompanying drawings.

如图1所示，光路改变组件20包括：两个棱镜，两个棱镜分别为第一棱镜21和第二棱镜22，第一棱镜21设置于镜片组10的像侧，第一棱镜21具有第一光学面210，第二棱镜22位于第一棱镜21的第一光学面210的出射侧，第二棱镜22具有第二光学面220。也就是说，光路改变组件20包括第一棱镜21和第二棱镜22，其中第一棱镜21放置在镜片组10的一侧，第一棱镜21具有第一光学面210，外部光线进入镜片组10之后通过第一棱镜21的第一光学面210反射，第二棱镜22位于第一棱镜21的第一光学面210的出射侧，第二棱镜22具有第二光学面220，外部光线经第一棱镜21的第一光学面210反射后，通过第二棱镜22的第二光学面220射出，这样通过两个光学面对光路的改变，可以将光线传递至图像处理器30，而且采用第一棱镜21和第二棱镜22的组合可以更好地减小沿着镜片组10光轴方向的模组长度。As shown in FIG. 1, the optical path changing component 20 includes two prisms. The two prisms are a first prism 21 and a second prism 22. The first prism 21 is arranged on the image side of the lens group 10, and the first prism 21 has a An optical surface 210, the second prism 22 is located on the exit side of the first optical surface 210 of the first prism 21, and the second prism 22 has a second optical surface 220. That is, the optical path changing component 20 includes a first prism 21 and a second prism 22, wherein the first prism 21 is placed on one side of the lens group 10, the first prism 21 has a first optical surface 210, and external light enters the lens group 10. It is then reflected by the first optical surface 210 of the first prism 21, the second prism 22 is located on the exit side of the first optical surface 210 of the first prism 21, the second prism 22 has a second optical surface 220, and external light passes through the first prism After the first optical surface 210 of 21 is reflected, it is emitted through the second optical surface 220 of the second prism 22. In this way, the light can be transmitted to the image processor 30 through the change of the optical path through the two optical surfaces, and the first prism 21 is used. The combination with the second prism 22 can better reduce the length of the module along the optical axis of the lens group 10.

其中，如图1所示，第一光学面对应第一棱镜的第一光学面220，第一棱镜21和第二棱镜22在垂直于光轴的方向间隔设置，镜片组10和图像传感器30在垂直于光轴的方向间隔设置。换言之，最后的发射光学面就是第二发射光学面220，第一棱镜21和第二棱镜22垂直于光轴的方向放置，且第一棱镜21和第二棱镜22之间有距离间隔，镜片组10和图像传感器30也垂直于光轴的方向放置，且镜片组10和图像传感器30之间也有间隔。如此设置的摄像头模组1结构简单且紧凑，可以有效缩短其在光轴方向上的延伸长度。Wherein, as shown in FIG. 1, the first optical surface corresponds to the first optical surface 220 of the first prism, the first prism 21 and the second prism 22 are arranged at intervals in the direction perpendicular to the optical axis, the lens group 10 and the image sensor 30 It is arranged at intervals in the direction perpendicular to the optical axis. In other words, the last emitting optical surface is the second emitting optical surface 220. The first prism 21 and the second prism 22 are placed perpendicular to the optical axis, and there is a distance between the first prism 21 and the second prism 22. The lens group 10 and the image sensor 30 are also placed perpendicular to the direction of the optical axis, and there is also an interval between the lens group 10 and the image sensor 30. The camera module 1 thus arranged has a simple and compact structure, and can effectively shorten its extension length in the optical axis direction.

具体地，如图1所示，第一棱镜21和第二棱镜22均为直角棱镜，第一棱镜21具有第一直角面211、第二直角面212和第一斜面，第二棱镜22具有第三直角面221、第四直角面222和第二斜面，第一直角面211与第四直角面222平行且共面，第二直角面212与第三直角面221平行，第一直角面211垂直于光轴，第一斜面为第一光学面210，第二斜面为第二光学面220。这样设置，第一棱镜21和第二棱镜22布置合理，可以使得光线在反射组件光路改变组件20内有效反射传递，而且也可以更好地方便反射组件光路改变组件20的设置，可以使得摄像头模组1结构更加紧凑。Specifically, as shown in FIG. 1, the first prism 21 and the second prism 22 are both right-angled prisms. The first prism 21 has a first right-angled surface 211, a second right-angled surface 212, and a first inclined surface, and the second prism 22 has a first right-angled surface. The three right-angled surfaces 221, the fourth right-angled surface 222 and the second inclined surface, the first right-angled surface 211 and the fourth right-angled surface 222 are parallel and coplanar, the second right-angled surface 212 is parallel to the third right-angled surface 221, and the first right-angled surface 211 is perpendicular On the optical axis, the first inclined surface is the first optical surface 210 and the second inclined surface is the second optical surface 220. With this arrangement, the first prism 21 and the second prism 22 are reasonably arranged, which can effectively reflect and transmit the light in the optical path changing assembly 20 of the reflective assembly, and it can also better facilitate the setting of the optical path changing assembly 20 of the reflective assembly, which can make the camera model Group 1 has a more compact structure.

当然，棱镜的数量不限于两个，如图2所示，在上一个实施例的基础上，光路改变组件20还包括：第三棱镜23，第三棱镜23位于第二棱镜22的第二光学面的出射侧，第三棱镜23具有第三光学面230。也就是说，当光线从第二棱镜22的第二光学面射出后，经过第三棱镜23的第三光学面230，将光线传递至图像处理器30，由此，设置第三棱镜23，通过第三光学面230的光路传递，也可以将光线传递至图像处理器30，而且采用第三棱镜23可以更好地减小沿着镜片组10光轴方向的模组长度。Of course, the number of prisms is not limited to two. As shown in FIG. 2, based on the previous embodiment, the optical path changing component 20 further includes: a third prism 23, which is located on the second optical surface of the second prism 22 On the exit side, the third prism 23 has a third optical surface 230. That is to say, after the light is emitted from the second optical surface of the second prism 22, it passes through the third optical surface 230 of the third prism 23 and transmits the light to the image processor 30, thereby setting the third prism 23 to pass through the third optical surface. The light path transmission of the optical surface 230 can also transmit the light to the image processor 30, and the use of the third prism 23 can better reduce the length of the module along the optical axis of the lens assembly 10.

其中，如图2所示，第三光学面230为最后的光学面，镜片组10、图像传感器30和第三棱镜23在垂直于光轴的方向间隔设置，图像传感器30位于镜片组10和第三棱镜23之间。如此设置第三棱镜23的位置，可以使得摄像头模组1结构简单且紧凑，并且也可以有效缩短其在光轴方向上的延伸长度。Wherein, as shown in FIG. 2, the third optical surface 230 is the final optical surface, the lens group 10, the image sensor 30, and the third prism 23 are arranged at intervals in a direction perpendicular to the optical axis, and the image sensor 30 is located in the lens group 10 and the third prism. Between 23. Setting the position of the third prism 23 in this way can make the structure of the camera module 1 simple and compact, and can also effectively shorten its extension length in the optical axis direction.

根据本公开的另一个可选实施例，多个光学改变元件均为反射镜。当然，除了使用棱镜，也可以用反射镜替代，反射镜的效果与棱镜的效果相同，采用反射镜的方式可以使得光路改变组件20结构简单，易于布置，而且此种结构的光路改变组件20也可以方便驱动组件驱动。需要说明的是，在光学改变元件为反射镜时，其也可以按照图1和图2所示的布置棱镜的方式进行布置。According to another optional embodiment of the present disclosure, the plurality of optical changing elements are all mirrors. Of course, in addition to using a prism, a mirror can also be used instead. The effect of the mirror is the same as that of the prism. The use of a mirror can make the light path changing assembly 20 simple in structure and easy to arrange, and the light path changing assembly 20 of this structure is also It is convenient to drive the component drive. It should be noted that when the optical changing element is a reflecting mirror, it can also be arranged in the manner of arranging prisms as shown in FIG. 1 and FIG. 2.

根据本公开的再一个可选实施例，多个光学改变元件的一部分为棱镜且另一部分为反射镜。也就是说，此种方式采用了棱镜和反射镜的组合。同样，效果与均设为棱镜和均设为反射镜的效果相同，易于布置，可以方便驱动组件驱动。需要说明的是，在部分光学改变元件为反射镜时，其也可以按照图1和图2所示的布置棱镜的方式进行布置。According to still another optional embodiment of the present disclosure, a part of the plurality of optical changing elements is a prism and the other part is a mirror. In other words, this method uses a combination of prisms and mirrors. Similarly, the effect is the same as that of both prisms and mirrors. It is easy to arrange and can facilitate driving components. It should be noted that when some of the optical changing elements are mirrors, they can also be arranged in the manner of arranging prisms as shown in FIG. 1 and FIG. 2.

其中，光学改变组件20还可以仅包括一个光学改变元件，该光学改变元件可以为棱镜，棱镜具有至少两个光学面。例如，如图3所示，棱镜可以呈倒梯形，其具有两个相对的光学面。将棱镜设为至少两个光学面，通过至少两个光学面的光路改变，可以减小镜片组10的轴向长度，从而可以减小摄像头模组1沿着镜片组10光轴方向的模组长度，从而可以实现摄像头模组1光轴方向小型化设计的目标。The optical changing component 20 may also include only one optical changing element, and the optical changing element may be a prism, and the prism has at least two optical surfaces. For example, as shown in FIG. 3, the prism may be in the shape of an inverted trapezoid, which has two opposing optical surfaces. The prism is set to at least two optical surfaces. By changing the optical paths of the at least two optical surfaces, the axial length of the lens group 10 can be reduced, so that the module of the camera module 1 along the optical axis of the lens group 10 can be reduced. Length, so as to achieve the goal of miniaturization in the direction of the optical axis of the camera module 1.

根据本公开的一个可选实施例，驱动组件可以为多个，多个驱动组件可以与多个光学改变元件一一对应，这样每个光学改变元件均对应有一个驱动组件，这样可以采用单独驱动或者同步驱动的方式，从而可以保证光路改变组件20的调节灵活性。According to an optional embodiment of the present disclosure, there may be multiple drive assemblies, and the multiple drive assemblies may correspond to multiple optical changing elements one-to-one, so that each optical changing element corresponds to one drive assembly, so that a separate drive can be used. Or the synchronous driving mode can ensure the adjustment flexibility of the optical path changing assembly 20.

例如，如图1所示，驱动组件为两个，第一棱镜21和第二棱镜22分别设置于两个驱动组件上，两个驱动组件同步驱动第一棱镜21和第二棱镜22沿光轴方向移动。也就是说，需要两个驱动组件，第一棱镜21和第二棱镜22可以直接设置于两个驱动组件上，两个驱动组件同步驱动第一棱镜21和第二棱镜22作为一个整体沿光轴方向移动，通过两个驱动组件同步驱动光路改变组件20的方式，可以减小沿着镜片组10光轴方向的模组长度，也可以实现自动对焦，从而避免移动质量较大的镜片组10。For example, as shown in FIG. 1, there are two driving components, the first prism 21 and the second prism 22 are respectively arranged on the two driving components, and the two driving components synchronously drive the first prism 21 and the second prism 22 along the optical axis. Move in direction. In other words, two driving components are required. The first prism 21 and the second prism 22 can be directly arranged on the two driving components, and the two driving components synchronously drive the first prism 21 and the second prism 22 as a whole along the optical axis. Directional movement, by synchronously driving the optical path changing assembly 20 by the two driving components, the length of the module along the optical axis of the lens group 10 can be reduced, and auto-focusing can also be realized, thereby avoiding the movement of the lens group 10 with larger mass.

根据本公开的另一个可选实施例，驱动组件仅为一个，光路改变组件20整体设置于驱动组件。如此设置的驱动组件结构简单，可以实现整体驱动，而且可以降低成本。According to another optional embodiment of the present disclosure, there is only one driving component, and the optical path changing component 20 is integrally disposed in the driving component. The drive assembly thus arranged has a simple structure, can realize overall drive, and can reduce costs.

可选地，驱动组件为音圈马达、压电马达和步进马达中的至少一种。也就是说，通过音圈马达、压电马达和步进马达中的一种，其中：音圈马达主要应用于小行程、高速、高加速运动，适合用于狭小的空间，最常见的是手机摄像头中的自动对焦功能就是完全由整个驱动器来完成的；压电马达功率密度比普通马达高得多，输出多为低速大推力，可实现直接驱动负载，并且内部不存在磁场，机械振动频率在可听范围外，因此对外界的电磁干扰和噪声影响很小；步进电机外表温度在摄氏80-90度完全正常，力矩会随转速的升高而下降，在低速时可以正常运转。Optionally, the driving component is at least one of a voice coil motor, a piezoelectric motor, and a stepping motor. That is to say, through one of voice coil motors, piezoelectric motors and stepping motors, among them: voice coil motors are mainly used in small strokes, high speed, high acceleration motion, suitable for small spaces, the most common is mobile phones The autofocus function in the camera is completely completed by the entire driver; the power density of the piezoelectric motor is much higher than that of the ordinary motor, and the output is mostly low-speed and high-thrust, which can directly drive the load, and there is no internal magnetic field. The mechanical vibration frequency is Outside the audible range, it has little impact on external electromagnetic interference and noise; the surface temperature of the stepper motor is completely normal at 80-90 degrees Celsius, and the torque will decrease with the increase of the speed, and it can operate normally at low speeds.

具体地，镜片组10包括：镜筒和多个透镜，多个透镜设置于镜筒内且在光轴方向层叠设置。这样可以使得多个透镜能够使得将物侧的光线有效传递至反射组件光路改变组件20，而且也有利于镜头镜片组10和反射组件光路改变组件20的布置。Specifically, the lens group 10 includes a lens barrel and a plurality of lenses, and the plurality of lenses are arranged in the lens barrel and stacked in the optical axis direction. In this way, a plurality of lenses can effectively transmit the light on the object side to the optical path changing assembly 20 of the reflective assembly, and it is also beneficial to the arrangement of the lens lens group 10 and the optical path changing assembly 20 of the reflective assembly.
