The current periscopic long-focus optical lens can achieve long-focus shooting, so that the thickness of the device housing does not need to be too large. How to provide an optical lens and a camera module with a large aperture, long focal length, large target surface and small volume has become a problem that the industry needs to face. SUMMARY

[0004] Embodiments of the present application provide an optical lens, a camera module and an electronic device, which can achieve a large aperture, long focal length, large target surface and small volume.

[0005] Embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, the present application provides an optical lens, comprising: a catadioptric lens, a lens group and a light folding member. The catadioptric lens has a first transmission surface, a first reflection surface, a second reflection surface and a second transmission surface. The first transmission surface and the second reflection surface are located on the object side of the catadioptric lens, and the second reflection surface is located in the paraxial region. The first transmission surface is arranged around the second reflection surface. The first reflection surface and the second transmission surface are located on the image side of the catadioptric lens, and the second transmission surface is located in the paraxial region. The first reflection surface is arranged around the second transmission surface. The lens group is located on the image side of the catadioptric lens. The light rays emitted by the second transmission surface can be projected to the object side of the lens group. The light rays emitted by the lens group can be emitted after being reflected at least twice in the light folding member.

[0007] The optical lens provided by the embodiment of the present application combines a catadioptric lens, a lens group and a light folding piece. Incident light is refracted at a first transmission surface of the catadioptric lens, and is reflected at a first reflection surface and a second reflection surface in turn, and is refracted out at a second transmission surface. After the light passes through the lens group, the light is reflected multiple times in the light folding piece and is emitted. The catadioptric lens can realize twice light reflection and a large aperture, the lens group can realize light gathering and adjustment, and the light folding piece can realize multiple light reflection. The optical lens has a long back focal magnification optical path, a large equivalent focal length, and can be used in combination with a large target surface image sensor to realize high-precision and high-resolution shooting. The folded optical paths of the catadioptric lens and the light folding piece make the height and volume of the optical lens and the camera module small, and the shoulder height of the camera module low.

The focusing motor only needs to drive the lens group and the first carrier to move, without driving the catadioptric lens to move, so the load is smaller, and the required driving force can be smaller. By driving the lens group to move to achieve focusing by the focusing motor, and driving the image sensor to move to achieve optical anti-shake by the anti-shake motor, the stroke and the load weight of the focusing motor can be reduced, and the implementation difficulty of the focusing motor is lower.

[0069] In an optional implementation, in the case that the lens group is arranged on the first carrier, the focusing motor can be arranged on the outer periphery of the lens group. The focusing motor only needs to drive the lens group and the first carrier, and the load is smaller. A smaller focusing motor can provide a certain electromagnetic driving force to drive the first carrier and the lens group to move.

[0070] In an alternative implementation, the first carrier is provided with a focusing coil, and the first base is provided with two focusing magnets, which are arranged along the radial direction of the lens group on both sides of the lens group. The two focusing magnets and the focusing coil cooperate to drive the first carrier and the lens group to move along the optical axis, thereby achieving focusing.

The first seat has a first opening through which the object side of the catadioptric lens is exposed. The first seat has a second opening through which one end of the lens group is aligned. The light folding element is arranged in the second seat. The first seat and the second seat are mounted on the third seat, and the image sensor and the anti-shake motor are arranged in the third seat.

[0072] In an alternative implementation, the camera module further includes a first support and a second support.

The anti-shake motor drives the second support and the first support to move, i.e., the anti-shake motor drives the focusing motor to move, and then drives the image sensor to translate on the first plane, so as to compensate for the movement of the image sensor and realize optical anti-shake. The focusing motor drives the image sensor to move to realize focusing, and the anti-shake motor drives the image sensor to move to realize optical anti-shake, so the focusing motor does not need to drive the heavy load of the catadioptric lens and the lens group to move, the structure of the focusing motor is relatively simple, and the assembly difficulty is relatively small.

[0150] For the convenience of understanding, the technical terms involved in the present application will be explained and described below.

[0151] Lens: is a component that uses the refraction principle of lens to make the light rays of the scene pass through the lens to form a clear image on the focusing plane.

[0152] Optical axis (OA): The direction in which an optical system transmits light, referenced to the chief ray of the central field of view. For symmetrical transmissive systems, it generally coincides with the center of rotation of the optical system. For off-axis and reflective systems, the optical axis also appears as a broken line.

[0153] Object side, image side: The side where the object is located is called the object side, and the surface of the lens close to the object side can be called the object side surface. The side where the image of the object is located is called the image side, and the surface of the lens close to the image side can be called the image side surface.

[0154] Focal length: Also known as focal length, it is a measure of the convergence or divergence of light in an optical system. It refers to the distance from the optical center of the lens or lens group to the focal point when an infinite distant object passes through the lens or lens group and forms a clear image on the focal plane. It can also be understood as the vertical distance from the optical center (optical center) of the lens or lens group to the focal plane. From a practical point of view, it can be understood as the distance from the lens center to the imaging plane.

[0155] Effective focal length (EFL): The distance from the principal plane of the optical system to the corresponding focal point.

[0156] Equivalent focal length: The angle of view imaged on different size image sensors is converted into the focal length of the optical lens corresponding to the same angle of view imaged on a 135 camera module. This converted focal length is the 135 equivalent focal length, which is the equivalent focal length. That is, the 135 camera module is used as a standard to convert the focal length of a non-135 specification camera module into the focal length of a 135 camera module. Equivalent focal length = effective focal length of optical lens * focal length coefficient (or focal length multiple), where the focal length coefficient is the ratio of the diagonal length of the image sensor of the non-135 specification camera module to the diagonal length of the image sensor of the 135 specification camera module. For example, the effective focal length of the optical lens is 31mm, the diagonal length of the image sensor of the non-135 specification camera module is 4.8mm, and the diagonal length of the image sensor of the 135 specification camera module is 43.27mm. Then the equivalent focal length = 31*43.27 / 4.8≈280mm.

[0157] Focus: Focus, also known as focusing or focusing. The process of changing the position of the object distance and the distance between the camera and the object to make the photographed object clear is called focusing. Generally, digital cameras have multiple focusing methods, including automatic focusing, manual focusing, or multiple focusing methods.

[0158] Auto focus (AF): Auto focus is to use the light reflection principle of the object, the reflected light through the lens on the image sensor imaging and receiving, and then through the computer processing to get the object distance, and then according to the object distance to automatically move the lens to complete the focusing. The role of auto focus is to make different distance objects on the image sensor imaging clearly. The camera module usually controls the optical lens to move along the optical axis direction by the power structure such as voice coil motor (VCM) to adjust the distance between the lens and the image sensor, so as to realize auto focus.

[0159] Refractive index: If the light enters a certain non-absorbing uniform material, the reflection and refraction of light will occur at its interface. The refractive index n is equal to the ratio of the speed of light in vacuum c and the speed of light in medium v. In fact, the measurement of refractive index is measured by measuring the deflection angle caused by the refraction of light beam at the interface, and the formula describing the deflection degree is called Snell's law.

[0160] Total internal reflection (TIR): also known as total internal reflection, is an optical phenomenon. When light enters from a medium with a higher refractive index to a medium with a lower refractive index, if the incident angle is greater than a certain critical angle (the light is far away from the normal), the refracted light will disappear, and all the incident light will be reflected without entering the low refractive index medium. That is, total reflection refers to the phenomenon that when light is emitted from a dense medium (i.e. the refractive index of light in this medium is larger) to the interface of a sparse medium (i.e. the refractive index of light in this medium is smaller), all the light is reflected back into the original medium.

[0161] F-number (F-number, Fno), is the relative value (the reciprocal of relative aperture) of the focal length of the lens / the diameter of the lens. The smaller the F number, the more light is admitted in the same unit of time. The larger the F number, the smaller the aperture, the larger the depth of field, and the less obvious the blurring effect of the photograph.

[0162] Referring to (a) in FIG. 1, a camera module 1 of the related art includes an optical lens 11, an image sensor 12, a focusing motor and an anti-shake motor, the optical lens 11 includes a triangular prism 11a, a first lens group 11b and a second lens group 11c arranged in sequence, the image sensor 12 and the second lens group 11c are arranged to face each other on the image side. The focusing motor is used to drive the second lens group 11c to move along the optical axis to change the distance between the optical center of the optical lens 11 and the image sensor 12 to realize focusing. The anti-shake motor is used to drive the triangular prism 11a to tilt around two axes (parallel axes of Y axis and Z axis) to realize optical anti-shake.

[0163] Referring to (b) in FIG. 1, another camera module 2 of the related art includes an optical lens 21, an image sensor 22, a focusing motor, and an anti-shake motor. The optical lens 21 includes a power prism 21a, a first lens group 21b, a second lens group 21c, and a triangular prism 21d arranged in sequence. The triangular prism 21d is arranged opposite to the image sensor 22 on the light exit side. The focusing motor is configured to drive the second lens group 21c to move along the optical axis to change the distance between the optical center of the optical lens 21 and the image sensor 22 to achieve focusing. The anti-shake motor is configured to drive the image sensor 22 to move in a plane parallel to the XY plane to achieve optical anti-shake.

[0164] The above two optical lenses or camera modules can achieve certain telephoto shooting effects, but it is difficult to have large aperture, ultra-long focal length, large target surface, and small size. The optical lens or camera module with large aperture can improve the light amount to improve the brightness of the captured image, achieve a shallow depth of field effect, and improve the macro shooting capability. The camera module with a large target surface can achieve high-precision and high-resolution image capture. The optical lens or camera module with small size occupies less space in the device shell, so that the electronic device has a better appearance.

[0165] Referring to (a) and (b) in FIG. 2, an electronic device 10 is provided, which includes a device shell 200 and a camera module 100. The camera module 100 is arranged in the device shell 200. The device shell 200 is configured to mount components of the electronic device 10 and provide protection to reduce damage to the components caused by external factors. The camera module 100 is configured to capture still images or videos. The device shell 200 can be provided with one or more camera modules 100.

[0166] The electronic device 10 can be a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer, an e-book reader, a netbook, a personal digital assistant, a wearable device, an augmented reality (AR) device, a virtual reality (VR) device, a television, a drone, a sports camera, a drive recorder, a vehicle-mounted device, a robot, a kiosk, or the like.

[0167] Take the mobile phone as an example. The electronic device 10 includes a camera module 100, a device housing 200, and a display screen 300. The device housing 200 includes a back cover 210 and a middle frame 220. The display screen 300 and the back cover 210 are respectively arranged on opposite sides of the middle frame 220. The display screen 300 and the middle frame 220 can be connected by adhesion or the like. The middle frame 220 and the back cover 210 can be connected by adhesion, buckling or the like. The middle frame 220 and the back cover 210 can also be an integrally formed structure. The camera module 100 can be arranged on the back cover 210 as a rear camera module. The electronic device 10 can also include a battery, a mainboard, a receiver, a loudspeaker, a gyroscope, an accelerometer and the like. These devices can be arranged on the middle frame 220.

[0168] In some embodiments, referring to FIGS. 3-5, the camera module 100 includes an optical lens 110, an image sensor 120, a focusing motor 130, and an anti-shake motor 140. The image sensor 120 is located on the light exit side 110a of the optical lens 110. The optical lens 110 images the shooting object on the photosensitive surface of the image sensor 120. The image sensor 120 converts the light image on the photosensitive surface of the image sensor 120 into an electrical signal by using the photoelectric conversion function of the photoelectric device to capture an image or a video. The focusing motor 130 is used to adjust the distance between the optical center of the optical lens 110 and the image sensor 120 to achieve focusing. The anti-shake motor 140 is used to drive the image sensor 120 and / or the optical lens 110 to move to achieve optical anti-shake.

[0169] In some embodiments, the image sensor 120 can be a charge coupled device (CCD), a complementary metal oxide semiconductor (CMOS), or a thin film transistor (TFT), etc. The photosensitive surface side of the image sensor 120 can be provided with a filter 121, such as a blue glass (BG) infrared cut filter.

[0170] Referring to FIGS. 4-6, an optical lens 110 is provided, which includes a catadioptric lens 111, a lens group 112, and a light folding element 113. The catadioptric lens 111 has a first transmissive surface 111a, a first reflective surface 111b, a second reflective surface 111c, and a second transmissive surface 111d. The first transmissive surface 111a and the second reflective surface 111c are located on an object side surface 111e of the catadioptric lens 111, and the second reflective surface 111c is located in a near-axis region, and the first transmissive surface 111a is arranged around the second reflective surface 111c. The first reflective surface 111b and the second transmissive surface 111d are located on an image side surface 111f of the catadioptric lens 111, and the second transmissive surface 111d is located in a near-axis region, and the first reflective surface 111b is arranged around the second transmissive surface 111d. The lens group 112 is located on the image side of the catadioptric lens 111, and light rays emitted by the second transmissive surface 111d can be projected to an object side surface 112a of the lens group 112. Light rays emitted by the lens group 112 can be emitted after being reflected at least twice in the light folding element 113.

[0171] The second reflective surface 111c is located in a near-axis region, and the second transmissive surface 111d is located in a near-axis region. The near-axis region is a region close to the optical axis A1 of the catadioptric lens 111.

[0172] The lens group 112 can include one or more optical lenses 1121. When the lens group 112 includes multiple optical lenses 1121, the multiple optical lenses 1121 can be stacked along the optical axis A2 of the lens group 112. The object side surface 112a of the lens group 112 is the object side surface of the first optical lens in the lens group 112. The image side surface 112b of the lens group 112 is the image side surface of the last optical lens in the lens group 112.

[0173] The light emitting side of the light folding element 113 can serve as the light emitting side 110a of the optical lens 110, and is arranged opposite to the image sensor 120.

[0174] The optical lens 110 provided by the embodiment of the present application combines the catadioptric lens 111, the lens group 112 and the light folding member 113. The incident light is refracted at the first transmission surface 111a of the catadioptric lens 111, is reflected at the first reflection surface 111b and the second reflection surface 111c in sequence, and is refracted at the second transmission surface 111d to be emitted. After the light passes through the lens group 112, the light is emitted after being reflected multiple times in the light folding member 113. The catadioptric lens 111 can realize twice light reflection and a large aperture, the lens group 112 can realize light gathering and adjustment, and the light folding member 113 can realize multiple light reflection. The optical lens 110 has a long back focal magnification optical path, a large equivalent focal length, and can be used in combination with a large target surface image sensor 120 to realize high-precision and high-resolution shooting. By using the folded optical paths of the catadioptric lens 111 and the light folding member 113, in combination with FIG. 3, the height and volume of the optical lens 110 and the camera module 100 are small, and the shoulder height D1 of the camera module 100 is low.

[0175] For example, the equivalent focal length of the optical lens 110 of the embodiment can be greater than or equal to 200 mm, and the optical lens 110 can be referred to as a super telephoto optical lens. Compared with the aperture number (Fno) of 3.5 of the related art optical lens, the aperture number of the optical lens 110 of the embodiment can reach 2.6, and the light intake brightness can be improved by 80%.

[0176] The optical lens 110 of the embodiment can be used in combination with a large target surface image sensor 120, such as a 50-megapixel, 0.7-micron pixel size image sensor 120, to realize high-precision and high-resolution shooting.

[0177] Compared with the electronic device having the camera module of the related art, when the camera module 100 having the optical lens 110 of the embodiment is applied to the electronic device 10, the area of the camera module 100 on the main circuit board is reduced by more than 30%, and the occupied area is small and the structure is compact.

[0178] In some embodiments, referring to FIG. 5, the catadioptric lens 111 is a Cassegrain catadioptric lens, which can be composed of one or two lenses. In the case where the catadioptric lens 111 includes two lenses, the two lenses can be connected. The first reflection surface 111b can be an annular spherical surface or an annular aspherical surface. The second reflection surface 111c can be a circular spherical surface or a circular aspherical surface. In this way, the incident light is refracted at the first transmission surface 111a of the catadioptric lens 111, is reflected at the first reflection surface 111b and the second reflection surface 111c in sequence, and is refracted at the second transmission surface 111d to be emitted.

[0179] In some embodiments, referring to FIG. 5, the diameter of the catadioptric lens 111 is greater than or equal to 2 times the diameter of the lens group 112. The diameter of the catadioptric lens 111 is the effective aperture of the first transmissive surface 111a of the catadioptric lens 111. The diameter of the lens group 112 is the effective aperture of the first lens in the lens group 112. The effective aperture of an optical element refers to the physical aperture of the optical element for refracting or reflecting light. Defining the diameter of the catadioptric lens 111 in the above range can achieve a large aperture, which is conducive to increasing the amount of light to improve the brightness of the captured image, achieving a shallow depth of field effect, and improving the macro shooting capability.

[0180] In some embodiments, referring to FIG. 5, the light folding element 113 can be a prism. The light folding element 113 has a third transmissive surface 113a and a fourth transmissive surface 113b. The third transmissive surface 113a is arranged opposite to the image side surface 112b of the lens group 112. The prism is easy to position and assemble, and the multiple reflective surfaces of the light folding element 113 are kept at a predetermined position and angle. The light emitted by the lens group 112 passes through the third transmissive surface 113a in a predetermined direction, then passes through the light folding element 113 multiple times by reflection, and then passes through the fourth transmissive surface 113b to exit the light folding element 113 in a predetermined direction. The prism can achieve multiple light reflections, form a long back focal length magnification optical path, and be used in combination with a large target area image sensor 120. The image sensor 120 is arranged opposite to the fourth transmissive surface 113b of the light folding element 113.

[0181] In some embodiments, referring to FIG. 5, the light folding element 113 is a prism, and the included angle between the plane where the third transmissive surface 113a is located and the first reflective surface of the prism through which the light emitted by the lens group 112 passes is in the range of [25°, 35°]. When the light enters the prism and is incident on the reflective surface, the incident angle will be greater than the critical angle, so that total reflection occurs on the reflective surface of the prism.

[0182] In other embodiments, when the light enters the prism and is incident on the reflective surface, a reflective layer can be arranged on the reflective surface to reflect more light on the reflective surface when the incident angle is less than the critical angle.

[0183] When the third transmissive surface 113a and the fourth transmissive surface 113b of the prism are arranged, there are multiple optional implementation manners. Two implementation manners are exemplarily given below.

[0184] The third transmission surface 113a and the fourth transmission surface 113b of the first prism are arranged in the following manner: referring to FIG. 4 and FIG. 5, the first optical axis A3 corresponding to the third transmission surface 113a and the second optical axis A4 corresponding to the fourth transmission surface 113b are parallel. When the optical lens 110 is applied to the camera module 100, the image sensor 120 and the fourth transmission surface 113b of the light folding element 113 are arranged oppositely. When a trapezoidal prism is used, the image sensor 120 and the lens group 112 can be arranged adjacently on the same side of the trapezoidal prism, so that the camera module 100 occupies less space. When a parallelogram prism is used, the image sensor 120 and the lens group 112 can be arranged on opposite sides of the parallelogram prism, so that the camera module 100 occupies less space.

[0185] For example, the distance between the first optical axis A3 and the second optical axis A4 can be greater than or equal to 8.5 mm, so that the lens group 112 can be arranged on the third transmission surface 113a of the light folding element 113, and the image sensor 120 with a large target surface can be arranged on the fourth transmission surface 113b of the light folding element 113.

[0186] The third transmission surface 113a and the fourth transmission surface 113b of the second prism are arranged in the following manner: the first optical axis A3 corresponding to the third transmission surface 113a and the second optical axis A4 corresponding to the fourth transmission surface 113b form a predetermined angle. When the optical lens 110 is applied to the camera module 100, the image sensor 120 and the fourth transmission surface 113b of the light folding element 113 are arranged oppositely. When a triangular prism is used, the image sensor 120 and the lens group 112 can be arranged on different sides of the triangular prism, so that the camera module 100 occupies less space.

[0187] For the above two arrangements of the third transmission surface 113a and the fourth transmission surface 113b, when the prism is applied to the camera module 100, the optical axis A2 of the lens group 112 coincides with the first optical axis A3 of the prism, which can be achieved by optical axis alignment process. The second optical axis A4 of the prism is perpendicular to the photosensitive surface of the image sensor 120, and the second optical axis A4 coincides with the center of the photosensitive surface of the image sensor 120. More light emitted by the lens group 112 enters the prism, and after multiple reflections in the prism, the light is emitted from the prism at the fourth transmission surface 113b, so that more light emitted by the prism is projected on the photosensitive surface of the image sensor 120.

[0188] There are various optional implementation manners for arranging the focusing motor 130, and four implementation manners are exemplarily given below.

[0189] The first implementation of the focusing motor 130: referring to FIG. 4, the optical axis A2 of the lens group 112 and the optical axis A1 of the catadioptric lens 111 coincide, and the focusing motor 130 is used to drive the catadioptric lens 111 and the lens group 112 to move along the optical axis A2 of the lens group 112. The position of the catadioptric lens 111 and the lens group 112 in the optical axis direction is adjusted by the focusing motor 130, so that the distance between the optical center of the optical lens 110 and the image sensor 120 is adjusted, and focusing is achieved.

[0190] The second implementation of the focusing motor 130: the focusing motor 130 is used to drive the image sensor 120 to move along the optical axis A5 of the image sensor 120. The position of the image sensor 120 in the optical axis direction is adjusted by the focusing motor 130, so that the distance between the optical center of the optical lens 110 and the image sensor 120 is adjusted, and focusing is achieved.

[0191] The third implementation of the focusing motor 130: the focusing motor 130 is used to drive the light folding member 113 to move along the optical axis A5 of the image sensor 120. The position of the light folding member 113 in the optical axis direction is adjusted by the focusing motor 130, so that the distance between the lens group 112 and the light folding member 113 is also synchronously changed, the distance between the optical center of the optical lens 110 and the image sensor 120 is adjusted, and focusing is achieved. The light folding member 113 can be a trapezoidal prism or a parallelogram prism.

[0192] The fourth implementation of the focusing motor 130: the catadioptric lens 111 and the lens group 112 are arranged in groups, and the focusing motor 130 is used to drive the lens group 112 to move along the optical axis A2 of the lens group 112. The position of the lens group 112 in the optical axis direction is adjusted by the focusing motor 130, so that the distance between the optical center of the optical lens 110 and the image sensor 120 is adjusted, and focusing is achieved.

[0193] The above-mentioned various focusing motors 130 can be implemented in the form of a voice coil motor, a piezoelectric motor, a shape memory alloy motor, etc. The movement of the driven part driven by the focusing motor 130 can be detected by a position sensor (such as a Hall sensor), and the position information of the driven part is fed back to the controller, so that the controller controls the working of the focusing motor 130 to accurately move the driven part to the predetermined position.

[0194] There are various optional implementation modes when the anti-shake motor 140 is arranged, and two implementation modes are exemplarily given below.

[0195] The first implementation of the anti-shake motor 140: referring to FIG. 4, the anti-shake motor 140 is used to drive the image sensor 120 to move in the optical axis vertical plane of the image sensor 120. The image sensor 120 is translated and / or rotated on the predetermined plane by the anti-shake motor 140, so that the image sensor 120 is moved to compensate, and optical anti-shake is achieved.

[0196] The second implementation of the anti-shake motor 140: the optical axis A2 of the lens group 112 and the optical axis Al of the catadioptric lens 111 coincide, and the anti-shake motor 140 is used to drive the catadioptric lens 111 and the lens group 112 to move in the optical axis vertical plane of the lens group 112. By driving the lens group 112 and the catadioptric lens 111 to translate and / or rotate in a predetermined plane by the anti-shake motor 140, the motion compensation of the lens group 112 and the catadioptric lens 111 is achieved, and optical image stabilization is realized.

[0197] The above-mentioned various anti-shake motors 140 can be implemented in the form of a voice coil motor, a piezoelectric motor, a shape memory alloy motor, etc. The movement of the moving part driven by the anti-shake motor 140 can be detected by a position sensor (such as a Hall sensor), and the position information of the moving part is fed back to the controller, so that the controller controls the anti-shake motor 140 to work, and the moving part is accurately moved to the predetermined position.

[0198] It can be understood that the above-mentioned various focusing motors 130 and various anti-shake motors 140 can be used in combination as needed.

[0199] For example, referring to FIG. 4, the camera module 100 of the embodiment adopts the first focusing motor 130 and the first anti-shake motor 140. The focusing motor 130 drives the catadioptric lens 111 and the lens group 112 to move along the optical axis A2 of the lens group 112, and the anti-shake motor 140 drives the image sensor 120 to move in the optical axis vertical plane.

[0200] For example, the camera module 100 of the embodiment adopts the first focusing motor 130 and the second anti-shake motor 140. The focusing motor 130 drives the catadioptric lens 111 and the lens group 112 to move along the optical axis A2 of the lens group 112, and the anti-shake motor 140 drives the catadioptric lens 111 and the lens group 112 to move in the optical axis vertical plane of the lens group 112.

[0201] For example, the camera module 100 of the embodiment adopts the second focusing motor 130 and the first anti-shake motor 140. The focusing motor 130 drives the image sensor 120 to move along the optical axis, and the anti-shake motor 140 drives the image sensor 120 to move in the optical axis vertical plane.

[0202] For example, the camera module 100 of the embodiment adopts the second focusing motor 130 and the second anti-shake motor 140. The focusing motor 130 drives the image sensor 120 to move along the optical axis, and the anti-shake motor 140 drives the catadioptric lens 111 and the lens group 112 to move in the optical axis vertical plane of the lens group 112.

[0203] Exemplarily, the camera module 100 of the embodiment adopts the third focusing motor 130 and the first anti-shake motor 140. The focusing motor 130 drives the light folding element 113 to move along the optical axis A5 of the image sensor 120, and the anti-shake motor 140 drives the image sensor 120 to move in the plane perpendicular to the optical axis. The light folding element 113 can be a trapezoidal prism, a parallelogram prism, etc., and the first optical axis A3 and the second optical axis A4 need to be parallel.

The focusing motor 130 is located at one side of the first carrier 151 along the first direction X. The focusing motor 130 is arranged at a position away from the image sensor 120. The focusing motor 130 occupies a certain space to generate a certain Lorentz force to drive the lens group 112 and the folded catadioptric lens 111 to move.

The camera module 100 further comprises a constraint assembly 154 for pressing the first carrier 151 towards the support 153 along the first direction X. The first carrier 151 is slidingly mounted on the first base 152 along a predetermined direction, and the constraint assembly 154 keeps a pressing tendency between the first carrier 151 and the support 153, which reduces the overturning of the first carrier 151 and improves the movement reliability of the first carrier 151.

[0222] For example, the support 153 can be a slide column extending along the moving direction of the first carrier 151, and the slide column is mounted on the first base 152. The first carrier 151 is provided with a plurality of spaced-apart slide grooves 1511 and a plurality of mating surfaces 1512. One of the slide columns is slidingly fitted with the wall surface of the slide groove 1511, and the other slide column is slidingly fitted with the mating surface 1512, so that the first carrier 151 is slidingly mounted on the first base 152 along a predetermined direction.

[0223] In some embodiments, referring to FIGS. 8-10, the constraint assembly 154 comprises a first magnetic member 1541 and a second magnetic member 1542. The first magnetic member 1541 is arranged on the first carrier 151, and the second magnetic member 1542 is arranged on the first base 152. The first magnetic member 1541 and the second magnetic member 1542 are spaced apart along the first direction X. The magnetic attraction between the first magnetic member 1541 and the second magnetic member 1542 presses the first carrier 151 towards the first base 152 along the first direction X, so that the first carrier 151 is not easily overturned relative to the first base 152.

[0224] One of the first magnetic member 1541 and the second magnetic member 1542 can be a magnet, and the other can be a magnetic conductive member.

[0226] Exemplarily, the focusing motor 130 is a voice coil motor, the first magnetic member 1541 is a magnet, and the second magnetic member 1542 is a magnetic conducting member. The first magnetic member 1541 and the focusing magnet 131 of the focusing motor 130 need to be kept away from each other, so as to reduce the magnetic interference on the focusing motor 130. The first magnetic member 1541 and the focusing motor 130 are arranged along the optical axis A2 of the lens group 112. The first base 152 is provided with two support members 153, and the first base 152 is provided with the two support members 153. Each support member 153 is arranged adjacent to one second magnetic member 1542. The first carrier 151 is provided with two first magnetic members 1541 correspondingly. Through the two groups of first magnetic members 1541 and second magnetic members 1542, the first carrier 151 can be reliably kept on the first base 152 and is not easy to overturn.

[0227] In some embodiments, referring to FIGS. 8-10, the focusing motor 130 includes a focusing magnet 131 and a focusing coil 132. One of the focusing magnet 131 and the focusing coil 132 is arranged on the first carrier 151, and the other is arranged on the first base 152. The focusing magnet 131 and the focusing coil 132 are arranged facing each other along the first direction X. The focusing magnet 131 and the focusing coil 132 cooperate to generate an electromagnetic driving force required for the movement of the first carrier 151. The first magnetic member 1541 is a magnet, and the second magnetic member 1542 is a magnetic conducting member. The projection of at least one second magnetic member 1542a on the vertical plane of the first direction X intersects with the projection of the focusing motor 130 on the vertical plane of the first direction X. There is a magnetic attraction force between the first magnetic member 1541 and the second magnetic member 1542, and there is also a magnetic attraction force between the focusing magnet 131 and the at least one second magnetic member 1542a. By increasing the magnetic attraction force, the first carrier 151 can be reliably pressed towards the first base 152 along the first direction X, so that the first carrier 151 is not easy to overturn.

[0228] Exemplarily, referring to FIGS. 8-10, the second magnetic member 1542a is a magnetic conducting member. One of the second magnetic members 1542a is mounted on the first base 152 and is arranged corresponding to the focusing magnet 131 of the first carrier 151 along the first direction X, so as to generate a magnetic attraction force between the second magnetic member 1542a and the focusing magnet 131.

[0229] For example, referring to FIGS. 11-13, the first magnetic member 1541 is a magnet, and the second magnetic member 1542 / 1542a is a magnetic conductive member. The second magnetic member 1542a is installed on the first base 152, and can be in an H shape or a U shape. The second magnetic member 1542a includes two vertical arms and a horizontal arm, and the two ends of the horizontal arm are connected to the two vertical arms, respectively. The two vertical arms are arranged one-to-one corresponding to the two first magnetic members 1541 of the first carrier 151, and a magnetic attraction force is formed between the vertical arm and the first magnetic member 1541. The horizontal arm and the focusing magnet 131 are arranged corresponding to each other along the first direction X to form a magnetic attraction force. Thus, a larger acting force is formed between the first carrier 151 and the first base 152.

[0232] The focusing motor 130 drives the catadioptric lens 111 and the lens group 112 to move to realize focusing, and the anti-shake motor 140 drives the image sensor 120 to move on the first plane to realize optical anti-shake. The anti-shake motor 140 and the focusing motor 130 are arranged separately, and in combination with FIG. 3, the shoulder height D1 of the camera module 100 is low. In the scene of the long focal length camera module 100, the anti-shake motor 140 drives the image sensor 120 to move, instead of driving the catadioptric lens 111 and the lens group 112 to move, and the load of the anti-shake motor 140 is small, and the reliability is good.

The first flexible plate 162 includes a first segment 1621, a second segment 1622, and a third segment 1623 connected in sequence. The first segment 1621 is substantially L-shaped, and the plane thereof is parallel to the XZ plane. The first segment 1621 is connected to the second carrier 155. The second segment 1622 extends along the second direction Y, and the plane thereof is parallel to the YZ plane. The third segment 1623 extends along the first direction X, and the plane thereof is parallel to the XY plane. The third segment 1623 is connected to the first circuit board 163. Two parts are located in different planes, that is, there is a bend between the two parts. The first flexible plate 162 is bent to reduce the reaction force when the first carrier 151 moves in the first plane. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The first direction X and the second direction Y are parallel to the first plane.

[0248] In some embodiments, referring to FIGS. 3, 4, and 7, the third base 164 is further included. The light folding element 113 is mounted on the third base 164. The first base 152 and the second base 156 are both connected to the third base 164. The first base 152 and the second base 156 are fixed on the third base 164 to combine the optical lens 110, the focusing motor 130, and the anti-shake motor 140 to form the modular camera module 100. The third base 164 has a slot, and the light folding element 113 can be mounted in the slot.

[0249] It can be understood that the light folding element 113 in the first camera module 100 can adopt a trapezoidal prism, a parallelogram prism, or the like.

[0250] The following describes an embodiment of a second camera module 100. Referring to FIGS. 17 to 19, the catadioptric lens 111 and the lens group 112 are both driven by the focusing motor 130 to move the lens group 112 to achieve focusing, and are driven by the anti-shake motor 140 to move the image sensor 120 to achieve optical anti-shake.

[0251] In some embodiments, referring to FIGS. 17-19, the optical axis A2 of the lens group 112 and the optical axis Al of the catadioptric lens 111 coincide, and the camera module 100 further includes a first carrier 151 and a first base 152. The catadioptric lens 111 and the lens group 112 are arranged in groups. The catadioptric lens 111 is fixed to the first base 152. The lens group 112 is arranged on the first carrier 151. The first carrier 151 is slidingly mounted on the first carrier 151 along the optical axis A2 of the lens group 112; the focusing motor 130 is configured to drive the first carrier 151 to move relative to the first base 152. By driving the catadioptric lens 111 and the lens group 112 to move along the optical axis by the focusing motor 130, the distance between the optical center of the optical lens 110 and the image sensor 120 is adjusted to achieve focusing. The focusing motor 130 only needs to drive the lens group 112 and the first carrier 151 to move, without driving the catadioptric lens 111 to move, so the load is smaller and the required driving force can be smaller.

[0252] The catadioptric lens 111 and the lens group 112 are driven to move by the focusing motor 130 to achieve focusing, and the image sensor 120 is driven to move by the anti-shake motor 140 to achieve optical anti-shake, which can reduce the stroke and load weight of the focusing motor 130, and the focusing motor 130 is easier to implement.

[0253] In some embodiments, referring to FIGS. 18 and 19, in the case where the lens group 112 is arranged on the first carrier 151, the focusing motor 130 can be arranged on the periphery of the lens group 112. The focusing motor 130 only needs to drive the lens group 112 and the first carrier 151, so the load is smaller, and a smaller focusing motor 130 can be used to provide a certain electromagnetic driving force to drive the first carrier 151 and the lens group 112 to move.

[0254] For example, the first carrier 151 is provided with a focusing coil 132, and the first base 152 is provided with two groups of focusing magnets 131, which are arranged on both sides of the lens group 112 along the radial direction of the lens group 112. The two groups of focusing magnets 131 and the focusing coil 132 cooperate to drive the first carrier 151 and the lens group 112 to move along the optical axis A2 to achieve focusing.

[0255] It can be understood that the second camera module 100 can refer to the embodiments of the first camera module 100 when setting the anti-shake motor 140.

[0256] In some embodiments, the third base 164 includes a first seat 1641, a second seat 1642, and a third seat 1643. The catadioptric lens 111 is disposed in the first seat 1641. The first seat 1641 has a first opening 1641a, and the object side 111e of the catadioptric lens 111 is exposed at the first opening 1641a. The first seat 1641 has a second opening 1641b, and one end of the lens group 112 is alignable with the second opening 1641b. The light folding element 113 is disposed in the second seat 1642. The first seat 1641 and the second seat 1642 are mounted to the third seat 1643, and the image sensor 120 and the anti-shake motor 140 are disposed in the third seat 1643. The optical lens 110, the focus motor 130, and the anti-shake motor 140 are combined to form the modular camera module 100. The different seats can be connected by bonding or other means.

[0257] In some embodiments, referring to FIGS. 19 and 20, the light folding element 113 is a parallelogram prism. The light folding element 113 has a third transmission surface 113a and a fourth transmission surface 113b, which are respectively located at opposite sides of the parallelogram prism. The lens group 112 and the image sensor 120 are located at the opposite sides of the parallelogram prism. The light emitted by the lens group 112 enters the third transmission surface 113a of the light folding element 113, and is sequentially reflected by multiple reflection surfaces before being emitted by the fourth transmission surface 113b to the image sensor 120. The light folding element 113 can achieve light folding, so that the camera module 100 occupies less space.

[0258] For example, the parallelogram prism has a pair of first sides and a pair of second sides. The parallelogram prism has a third transmission surface 113a, a third reflection surface 113c, a fourth reflection surface 113d, a fifth reflection surface 113e, a sixth reflection surface 113f, and a fourth transmission surface 113b. The third transmission surface 113a and the fourth reflection surface 113d are located at one of the first sides, and the fifth reflection surface 113e and the fourth transmission surface 113b are located at the other of the first sides. The third reflection surface 113c is located at one of the second sides, and the sixth reflection surface 113f is located at the other of the second sides. The optical axis A2 of the lens group 112 is perpendicular to the third transmission surface 113a. The fourth transmission surface 113b is parallel to the light receiving surface of the image sensor 120. The light emitted by the lens group 112 enters the first transmission surface 111a, and is sequentially reflected by the third reflection surface 113c, the fourth reflection surface 113d, the fifth reflection surface 113e, and the sixth reflection surface 113f before being emitted by the fourth transmission surface 113b to the image sensor 120.

[0259] It can be understood that the light folding element 113 in the second camera module 100 can also adopt the trapezoidal prism mode, which is described in the previous embodiments.

[0260] The third embodiment of the camera module 100 is described below. Referring to FIGS. 21-23, the image sensor 120 is moved by the focus motor 130 to achieve focusing, and the image sensor 120 is moved by the anti-shake motor 140 to achieve optical anti-shake.

[0261] In some embodiments, the camera module 100 further includes a first support 171 and a second support 172. The image sensor 120 is mounted on the first support 171, and the first support 171 is slidingly mounted on the second support 172 along the optical axis A5 of the image sensor 120. The focus motor 130 is configured to drive the first support 171 to move along the optical axis A5 of the image sensor 120. The first support 171 is driven by the focus motor 130 to move along the optical axis A5 of the image sensor 120, thereby driving the image sensor 120 to move along the optical axis A5, adjusting the distance between the optical center of the optical lens 110 and the image sensor 120, and achieving focusing.

[0262] For example, referring to FIGS. 24-26, the focus motor 130 is a moving-coil voice coil motor. The focus motor 130 includes a focus magnet 131 and a focus coil 132. The focus magnet 131 is disposed on the second support 172, and the focus coil 132 is disposed on the first support 171. The focus magnet 131 and the focus coil 132 are arranged to face each other, and the two cooperate to generate a Lorentz force along the optical axis A5 to drive the first support 171 to move along the optical axis A5.

[0263] In some embodiments, referring to FIGS. 24-26, the second support 172 is provided with a slide post 1721, and the first support 171 has a slide groove 1711 and a mating surface 1712 arranged at intervals. One of the slide post 1721 and the wall surface of the slide groove 1711 slidingly cooperates, and the other of the slide post and the mating surface 1712 slidingly cooperates, so that the first support 171 can be slidingly mounted on the second support 172 in a predetermined direction.

[0264] In some embodiments, referring to FIGS. 24-26, the camera module 100 further includes a third support 173 and a fourth support 174. The third support 173 is located between the second support 172 and the fourth support 174. The second support 172 and the third support 173 are supported by first rolling balls 175, and the second support 172 can translate along a first axis A6 relative to the third support 173. The third support 173 and the fourth support 174 are supported by second rolling balls 176, and the third support 173 can translate along a second axis A7 relative to the fourth support 174.

The first axis A6 and the second axis A7 are both parallel to the first plane. The first plane is parallel to the XY plane.

[0265] The second support 172, the third support 173 and the fourth support 174 combine the first ball 175 and the second ball 176, and the third support 173 is located between the second support 172 and the fourth support 174, so that the second support 172 can move in any direction in the first plane relative to the fourth support 174. The first support 171 is mounted on the second support 172, and the image sensor 120 is mounted on the first support 171, so that the image sensor 120 can move in any direction in the first plane. The second support 172 and the first support 171 are driven to move by the anti-shake motor 140, i.e. the anti-shake motor 140 drives the focusing motor 130 to move, and then drives the image sensor 120 to move in the first plane (the vertical plane of the optical axis of the image sensor 120), so that the image sensor 120 moves to compensate, and optical image stabilization is achieved.

[0266] The image sensor 120 is driven to move by the focusing motor 130 to achieve focusing, and the image sensor 120 is driven to move by the anti-shake motor 140 to achieve optical image stabilization. The focusing motor 130 does not need to drive the fold-back catadioptric lens 111 and the lens group 112 to move, the structure of the focusing motor 130 is relatively simple, and the assembly difficulty is relatively small.

[0267] In some embodiments, referring to FIGS. 25 and 26, the side of the third support 173 facing the second support 172 has a first guide groove 1731, and the side of the second support 172 facing the third support 173 has a second guide groove 1722.

The second support 172 and the third support 173 are kept at a distance, the first ball 175 moves in the area defined by the first guide groove 1731 and the second guide groove 1722, and the second support 172 can move along the direction of the first axis A6 relative to the third support 173, but cannot move in other directions. By arranging multiple sets of the first guide groove 1731, the second guide groove 1722 and the first ball 175, the second support 172 can move stably.

[0268] The third bracket 173 has a third guide slot 1732 on the side facing the fourth bracket 174, the fourth bracket 174 has a fourth guide slot 1741 on the side facing the third bracket 173, the third guide slot 1732 and the fourth guide slot 1741 are correspondingly arranged and both extend along the direction of the second axis A7, and the second ball 176 is arranged between the wall surface of the third guide slot 1732 and the wall surface of the fourth guide slot 1741.

[0278] In some embodiments, referring to FIG. 24 and FIG. 25, the first support 171 is connected with a pair of second flexible plates 181, each of which is arranged in a bent manner, so that the reaction force is small when the first support 171 and the image sensor 120 move. The pair of second flexible plates 181 are symmetrically arranged, and the symmetry plane passes through the center of the image sensor 120 and is parallel to the second direction Y. The pair of second flexible plates 181 can realize the transmission of control signals and electric energy to the power consuming devices of the first support 171, and can also make the force on the first support 171 symmetric, facilitating the driving of the first support 171 to move in three directions.

[0279] In some embodiments, referring to FIG. 24 and FIG. 25, one end of the second flexible plate 181 is electrically connected to the electric device on the first support 171, and the other end is located on the side of the fourth support 174 away from the first support 171.

The sixth segment 1816 is connected to the second circuit board 183. Two parts are located in different planes, that is, there is a bend between the two parts. The bending arrangement of the second flexible plate 181 makes the reaction force smaller when the first support 171 and the image sensor 120 move.

The control signal and the electric energy are transmitted to the second conductive part 182 and the second flexible plate 181 through the second circuit board 183. The control signal and the electric energy are transmitted to the anti-shake motor 140 of the fourth support 174 by the second conductive part 182 to drive the anti-shake motor 140 to work. The control signal and the electric energy are transmitted to the electric device, such as the image sensor 120 and the focusing motor 130, of the first support 171 by the second flexible plate 181 to drive the electric device to work.

[0286] It can be understood that the light folding piece 113 in the third camera module 100 can adopt a trapezoidal prism, a parallelogram prism or the like. For details, refer to the previous embodiments.

[0287] The fourth embodiment of the camera module 100 is introduced below. Referring to FIGS. 27-29, a light reflection member 114 is arranged between the catadioptric lens 111 and the lens group 112. The lens group 112 is driven to move by the focusing motor 130 to achieve focusing, and the image sensor 120 is driven to move by the anti-shake motor 140 to achieve optical anti-shake.
