[0159] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0160] For ease of understanding, the technical terms involved in this application are explained and described below.

[0161] Lens: A component that uses the refraction principle of the lens to allow the light of the scene to pass through the lens and form a clear image on the focusing plane.

[0162] Optical axis (OA): The direction in which light is transmitted by an optical system, with reference to the principal ray of the central field of view. For symmetrical transmission systems, it generally coincides with the centerline of rotation of the optical system. For off-axis and reflective systems, the optical axis may also appear as a broken line.

[0163] Object side and image side: With the lens as the boundary, the side where the object is located is the object side, and the surface of the lens close to the object side can be called the object side; with the lens as the boundary, the side where the image of the object is located is the image side, and the surface of the lens close to the image side can be called the image side.

[0164] 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 a lens or lens group to the focal point when an infinitely distant scene forms a clear image on the focal plane through a lens or lens group. It can also be understood as the vertical distance from the optical center (optical center) of a lens or lens group to the focal plane. From a practical point of view, it can be understood as the distance from the center of the lens to the imaging plane.

[0165] Effective focal length (EFL): The distance from the principal plane of an optical system to the corresponding focus.

[0166] Equivalent focal length: The viewing angle of the image on the image sensor of different sizes is converted into the focal length of the optical lens corresponding to the same imaging viewing angle on the 135 camera module. The converted focal length is the 135 equivalent focal length, that is, the equivalent focal length. That is, the 135 camera module is used as a standard to convert the focal length of the non-135 camera module into the focal length of the 135 camera module. Equivalent focal length = effective focal length of the 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 camera module to the diagonal length of the image sensor of the 135 camera module. For example, the effective focal length of the optical lens = 31mm, the diagonal length of the image sensor of the non-135 camera module is 4.8mm, and the diagonal length of the image sensor of the 135 camera module is 43.27mm, then the equivalent focal length = 31*43.27 / 4.8≈280mm.

[0167] Focus: Focus is also called light and focusing. The process of changing the distance between the object and the distance between the objects through the camera's focus mechanism to make the image of the object clear is called focusing. Usually, digital cameras have a variety of focusing methods, including automatic focus, manual focus, or multiple focus methods.

[0168] Auto focus (AF): Auto focus uses the principle of light reflection from the object to form an image on the image sensor after the reflected light passes through the lens, and then the object distance of the object is obtained through computer processing, and then the lens is automatically moved according to the object distance to complete the focusing. The function of auto focus is to make objects at different distances appear clear on the image sensor. The camera module usually uses a power structure such as a voice coil motor (VCM) to control the optical lens to move forward and backward along the optical axis to adjust the distance between the lens and the image sensor, thereby achieving auto focus.

[0169] Refractive index: If light enters a non-absorbing homogeneous material, light reflection and refraction will occur at its interface. The refractive index n is equal to the ratio of the speed of light in a vacuum, c, to the speed of light in the medium, v. In fact, the refractive index is measured by measuring the deflection angle caused by the refraction of the light beam at the interface. The formula describing the deflection is called Snell's law.

[0170] Total internal reflection (TIR): also known as total internal reflection, is an optical phenomenon. When light enters a medium with a higher refractive index from 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 medium with a lower refractive index. In other words, 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 of it is reflected back into the original medium.

[0171] The aperture number (F-number, Fno) is a relative value obtained by dividing the focal length of the lens by the diameter of the lens (the inverse of the relative aperture). The smaller the aperture F number, the more light enters in the same unit time. The larger the aperture number, the smaller the aperture, the greater the depth of field, and the less obvious the blur in the photo.

[0172] See also Figure 1(a) in the figure is a camera module 1 of the related art, comprising an optical lens 11, an image sensor 12, a focus motor and an anti-shake motor, wherein the optical lens 11 comprises a triangular prism 11a, a first lens group 11b and a second lens group 11c arranged in sequence, and the image sensor 12 and the image side of the second lens group 11c are arranged facing each other. The focus 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 achieve focusing. The anti-shake motor is used to drive the triangular prism 11a to tilt around two axes (parallel axes of the Y axis and the Z axis) to achieve optical image stabilization.

[0173] See also Figure 1 (b) in the figure shows another camera module 2 of the related art, comprising an optical lens 21, an image sensor 22, a focus motor and an anti-shake motor. The optical lens 21 comprises a power prism 21a, a first lens group 21b, a second lens group 21c and a triangular prism 21d arranged in sequence, and the light-emitting side of the triangular prism 21d faces the image sensor 22. The focus motor is used 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 used to drive the image sensor 22 to move on a plane parallel to the XY plane to achieve optical anti-shake.

[0174] The above two optical lenses or camera modules can achieve a certain long focal length shooting effect, but it is difficult to have a large aperture, ultra-long focal length, large target surface, and small size. Optical lenses or camera modules with large apertures can increase the amount of light entering to increase the brightness of the shooting picture, achieve a shallow depth of field effect, and enhance macro shooting capabilities. Camera modules with large target surfaces can achieve high-precision and high-resolution picture shooting. Optical lenses or camera modules with small volumes occupy less space in the device housing, giving the electronic device a better appearance.

[0175] See also Figure 2 In (a) and (b), the embodiment of the present application provides an electronic device 10, including a device housing 200 and a camera module 100, wherein the camera module 100 is disposed in the device housing 200. The device housing 200 is used to mount the components of the electronic device 10 and provide protection to reduce the damage of the components caused by external influences. The camera module 100 is used for shooting to capture still images or videos. The device housing 200 may be provided with one or more camera modules 100.

[0177] Take the electronic device 10 as an example, which is a mobile phone. 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 shell 210 and a middle frame 220. The display screen 300 and the back shell 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 bonding or the like. The middle frame 220 and the back shell 210 can be connected by bonding, snapping or the like. The middle frame 220 and the back shell 210 can also be an integrally formed structure. The camera module 100 can be arranged on the back shell 210 as a rear camera module. The electronic device 10 can also include devices such as a battery, a mainboard, an earpiece, a speaker, a gyroscope, an accelerometer, etc., which can be arranged in the middle frame 220.

[0178] In some embodiments, see Figures 3 to 5 The camera module 100 includes an optical lens 110, an image sensor 120, a focus motor 130, and an anti-shake motor 140. The image sensor 120 is located at the light-emitting side 110a of the optical lens 110. The optical lens 110 images the photographed scene on the photosensitive surface of the image sensor 120. The image sensor 120 utilizes the photoelectric conversion function of the photoelectric device to convert the light image on the photosensitive surface of the image sensor 120 into an electrical signal to capture an image or video. The focus 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 image stabilization.

[0179] In some embodiments, the image sensor 120 may be a charge coupled device (CCD), a complementary metal oxide semiconductor (CMOS), or a thin film transistor (TFT), etc. A filter 121 may be provided on one side of the photosensitive surface of the image sensor 120, such as a blue glass (BG) infrared cutoff filter.

[0180] See also Figures 4 to 6The embodiment of the present application provides an optical lens 110, including: a folding lens 111, a lens group 112 and an optical folding member 113. The folding lens 111 has a first transmission surface 111a, a first reflection surface 111b, a second reflection surface 111c and a second transmission surface 111d. The first transmission surface 111a and the second reflection surface 111c are located on the object side 111e of the folding lens 111, the second reflection surface 111c is located in the paraxial region, and the first transmission surface 111a is arranged around the second reflection surface 111c. The first reflection surface 111b and the second transmission surface 111d are located on the image side 111f of the folding lens 111, the second transmission surface 111d is located in the paraxial region, and the first reflection surface 111b is arranged around the second transmission surface 111d. The lens group 112 is located on the image side of the folding lens 111, and the light emitted from the second transmission surface 111d can be projected onto the object side 112a of the lens group 112. The light emitted from the lens group 112 can be reflected at least twice in the light folding element 113 before being emitted.

[0181] The second reflective surface 111 c is located in the paraxial region, and the second transmissive surface 111 d is located in the paraxial region. The paraxial region is a region close to the optical axis A1 of the folding lens 111 .

[0182] The lens group 112 may include one or more optical lenses 1121. When the lens group 112 includes a plurality of optical lenses 1121, the plurality of optical lenses 1121 may be stacked along the optical axis A2 direction 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.

[0183] The light-emitting side of the optical folding member 113 can serve as the light-emitting side 110 a of the optical lens 110 , and is disposed facing the image sensor 120 .

[0184] The optical lens 110 provided in the embodiment of the present application is combined with a folding lens 111, a lens group 112 and an optical folding element 113. The incident light is incident and refracted at the first transmission surface 111a of the folding lens 111, and is reflected by the first reflection surface 111b and the second reflection surface 111c in sequence, and then refracted and emitted at the second transmission surface 111d. After the light passes through the lens group 112, it is reflected multiple times in the optical folding element 113 and then emitted. The folding lens 111 can achieve two light reflections and a large aperture, the lens group 112 can achieve light gathering and adjustment, and the optical folding element 113 can achieve multiple light reflections. The optical lens 110 has a long back focus magnification optical path and a large equivalent focal length. It can be used in combination with an image sensor 120 with a large target surface to achieve high-precision and high-resolution shooting. Utilizing the folded optical paths of the folding lens 111 and the optical folding element 113, combined with Figure 3, so that the height and volume of the optical lens 110 and the camera module 100 are smaller, and the shoulder height D1 of the camera module 100 is lower.

[0185] For example, the equivalent focal length of the optical lens 110 of this embodiment can be greater than or equal to 200 mm, and the optical lens 110 can be called an ultra-telephoto optical lens. Compared with the aperture number (Fno) of the optical lens of the related art of 3.5, the aperture number of the optical lens 110 of this embodiment can reach 2.6, and the light input can be increased by 80%.

[0186] The optical lens 110 of this embodiment can be used in combination with an image sensor 120 with a large target surface, such as an image sensor 120 with 50 million pixels and a pixel size of 0.7 microns, to achieve high-precision and high-resolution photography.

[0187] Compared with electronic devices with camera modules in related technologies, when the camera module 100 with the optical lens 110 in this embodiment is applied to the electronic device 10, the area of ​​the main circuit board occupied by the camera module 100 is reduced by more than 30%, the occupied area is small, and the structure is compact.

[0188] In some embodiments, see Figure 5 The folding reflective lens 111 is a Cassegrain folding reflective lens, which can be composed of one or two lenses. In the case where the folding reflective 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. The incident light is incident and refracted on the first transmission surface 111a of the folding reflective lens 111, and after being reflected by the first reflection surface 111b and the second reflection surface 111c in sequence, it is refracted and emitted from the second transmission surface 111d.

[0189] In some embodiments, see Figure 5 , the diameter of the catadioptric lens 111 is greater than or equal to more than twice the diameter of the lens group 112. The diameter of the catadioptric lens 111 is the effective aperture of the first transmission 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 used to refract or reflect light. Limiting the diameter of the catadioptric lens 111 to the above range can achieve a large aperture, which is beneficial to increase the amount of light entering to increase the brightness of the captured image, achieve a shallow depth of field effect, and enhance macro shooting capabilities.

[0190] In some embodiments, see Figure 5The light folding member 113 may be a prism. The light folding member 113 has a third transmission surface 113a and a fourth transmission surface 113b. The third transmission surface 113a and the image side surface 112b of the lens group 112 are arranged to face each other. The prism is easy to position and assemble, so that the multiple reflection surfaces of the light folding member 113 are maintained at a predetermined position and angle. After the light emitted from the lens group 112 passes through the third transmission surface 113a along a predetermined direction, it is reflected multiple times in the light folding member 113, and then passes through the fourth transmission surface 113b to emit out of the light folding member 113 along a predetermined direction. The prism can realize multiple light reflections to form a long back focus magnification optical path, and can be used in combination with the image sensor 120 with a large target surface. The image sensor 120 and the fourth transmission surface 113b of the light folding member 113 are arranged to face each other.

[0191] In some embodiments, see Figure 5 The light folding element 113 is a prism, and the angle between the plane where the third transmission surface 113a is located and the first reflection surface of the prism through which the light emitted from the lens group 112 passes is in the range of [25°, 35°]. When the light enters the prism and shines on the reflection surface, the incident angle will be greater than the critical angle, and total reflection can occur on the reflection surface of the prism.

[0192] In other embodiments, when light enters the prism and strikes the reflective surface, when the incident angle is less than the critical angle, a reflective layer may be provided on the reflective surface so that more light is reflected on the reflective surface.

[0193] There are multiple optional implementations when setting the third transmission surface 113a and the fourth transmission surface 113b of the prism. Two implementations are given as examples below.

[0194] The third transmission surface 113a and the fourth transmission surface 113b of the first prism are arranged as follows: Figure 4 , Figure 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 optical folding member 113 are arranged opposite to each other. When a trapezoidal prism is used, the image sensor 120 and the lens group 112 can be arranged adjacent to each other 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.

[0195] Exemplarily, 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 optical folding element 113, and the image sensor 120 with a large target surface can be arranged on the fourth transmission surface 113b of the optical folding element 113.

[0196] The third transmission surface 113a and the fourth transmission surface 113b of the second prism are arranged in such a way that a predetermined angle is formed between 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. When the optical lens 110 is applied to the camera module 100, the image sensor 120 and the fourth transmission surface 113b of the optical folding member 113 are arranged opposite to each other. 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.

[0197] For the above two configurations 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 through an 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 from the lens group 112 enters the prism, and after multiple reflections from the prism, the light emits the prism at the fourth transmission surface 113b, so that more prism light is projected on the photosensitive surface of the image sensor 120.

[0198] There are multiple optional implementations when setting the focus motor 130 , and four implementations are given as examples below.

[0199] First implementation of the focus motor 130: see Figure 4 , the optical axis A2 of the lens group 112 coincides with the optical axis A1 of the catadioptric lens 111, and the focus 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 focus motor 130 adjusts the positions of the catadioptric lens 111 and the lens group 112 in the optical axis direction, so that the distance between the optical center of the optical lens 110 and the image sensor 120 is adjusted to achieve focusing.

[0200] Second implementation of the focus motor 130: The focus motor 130 is used to drive the image sensor 120 to move along the optical axis A5 direction of the image sensor 120. The focus motor 130 adjusts the position of the image sensor 120 in the optical axis direction, so that the distance between the optical center of the optical lens 110 and the image sensor 120 is adjusted to achieve focusing.

[0201] The third implementation of the focus motor 130: The focus motor 130 is used to drive the optical folding member 113 to move along the optical axis A5 direction of the image sensor 120. The position of the optical folding member 113 in the optical axis direction is adjusted by the focus motor 130, and the distance between the lens group 112 and the optical folding member 113 is also changed synchronously, so that the distance between the optical center of the optical lens 110 and the image sensor 120 is adjusted to achieve focusing. The optical folding member 113 can be a trapezoidal prism or a parallelogram prism.

[0202] A fourth implementation of the focus motor 130: the catadioptric lens 111 and the lens group 112 are arranged in groups, and the focus motor 130 is used to drive the lens group 112 to move along the optical axis A2 direction of the lens group 112. The focus motor 130 adjusts the position of the lens group 112 in the optical axis direction, so that the distance between the optical center of the optical lens 110 and the image sensor 120 is adjusted to achieve focusing.

[0203] The above-mentioned various focus motors 130 can be implemented by voice coil motors, piezoelectric motors, shape memory alloy motors, etc. The focus motor 130 drives the moving part to move, and the position sensor (such as a Hall sensor) can be used to detect the position of the moving part, and the position information of the moving part is fed back to the controller, and the controller controls the focus motor 130 to work, so that the moving part moves accurately to the predetermined position.

[0204] There are multiple optional implementations when setting the anti-shake motor 140 , and two implementations are given as examples below.

[0205] The first implementation method of the anti-shake motor 140: Figure 4 The anti-shake motor 140 is used to drive the image sensor 120 to move on a plane perpendicular to the optical axis of the image sensor 120. The anti-shake motor 140 drives the image sensor 120 to translate and / or rotate on a predetermined plane, so that the image sensor 120 is motion-compensated and optical anti-shake is achieved.

[0206] A second implementation of the anti-shake motor 140: the optical axis A2 of the lens group 112 coincides with the optical axis A1 of the catadioptric lens 111, and the anti-shake motor 140 is used to drive the catadioptric lens 111 and the lens group 112 to move on a plane perpendicular to the optical axis of the lens group 112. The anti-shake motor 140 drives the lens group 112 and the catadioptric lens 111 to translate and / or rotate on a predetermined plane, so that the lens group 112 and the catadioptric lens 111 are compensated for their motion, thereby achieving optical anti-shake.

[0207] The above-mentioned various anti-shake motors 140 can be implemented by voice coil motors, piezoelectric motors, shape memory alloy motors, etc. The anti-shake motor 140 drives the moving part to move, and the position of the moving part 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, and the controller controls the anti-shake motor 140 to work, so that the moving part moves accurately to the predetermined position.

[0208] It is understandable that the above-mentioned multiple focus motors 130 and multiple anti-shake motors 140 can be used in combination as needed.

[0209] For example, see Figure 4The camera module 100 of this embodiment adopts the first focus motor 130 and the first anti-shake motor 140. The focus motor 130 drives the reflective lens 111 and the lens group 112 to move along the optical axis A2 direction of the lens group 112, and the anti-shake motor 140 drives the image sensor 120 to move on the plane perpendicular to the optical axis.

[0210] Exemplarily, the camera module 100 of this embodiment adopts a first focus motor 130 and a second anti-shake motor 140. The focus motor 130 drives the reflective lens 111 and the lens group 112 to move along the optical axis A2 direction of the lens group 112, and the anti-shake motor 140 drives the reflective lens 111 and the lens group 112 to move on a plane perpendicular to the optical axis of the lens group 112.

[0211] Exemplarily, the camera module 100 of this embodiment adopts the second focus motor 130 and the first anti-shake motor 140. The focus 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 on the plane perpendicular to the optical axis.

[0212] Exemplarily, the camera module 100 of this embodiment adopts a second focus motor 130 and a second anti-shake motor 140. The focus motor 130 drives the image sensor 120 to move along the optical axis, and the anti-shake motor 140 drives the reflective lens 111 and the lens group 112 to move on a plane perpendicular to the optical axis of the lens group 112.

[0213] Exemplarily, the camera module 100 of this embodiment uses the third focus motor 130 and the first anti-shake motor 140. The focus motor 130 drives the optical folding member 113 to move along the optical axis A5 direction of the image sensor 120, and the anti-shake motor 140 drives the image sensor 120 to move on the plane perpendicular to the optical axis. The optical folding member 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.

[0214] Exemplarily, the camera module 100 of this embodiment uses the third focus motor 130 and the second anti-shake motor 140. The focus motor 130 drives the optical folding member 113 to move along the optical axis A5 direction of the image sensor 120, and the anti-shake motor 140 drives the catadioptric lens 111 and the lens group 112 to move on the plane perpendicular to the optical axis of the lens group 112. The optical folding member 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.

[0215] Exemplarily, the camera module 100 of this embodiment adopts the fourth focus motor 130 and the first anti-shake motor 140, the reflective lens 111 and the lens group 112 are arranged in groups, the focus motor 130 drives the lens group 112 to move along the optical axis, and the anti-shake motor 140 drives the image sensor 120 to move on the plane perpendicular to the optical axis.

[0216] Exemplarily, the camera module 100 of this embodiment adopts the fourth focus motor 130 and the second anti-shake motor 140, the reflective lens 111 and the lens group 112 are arranged in groups, the focus motor 130 drives the lens group 112 to move along the optical axis, and the anti-shake motor 140 drives the reflective lens 111 and the lens group 112 to move on the plane perpendicular to the optical axis of the lens group 112.

[0217] In some embodiments, see Figure 4 , Figure 5 The object side surface 112a of the lens group 112 and the second transmission surface 111d are arranged facing each other, and the optical axis A2 of the lens group 112 coincides with the optical axis A1 of the catadioptric lens 111. The outgoing light of the catadioptric lens 111 can directly enter the lens group 112.

[0218] In some embodiments, see Figure 4 , Figure 5 , Figure 7 The folding reflective lens 111 can be installed on a structural member (such as a carrier or a seat), and the structural member has an inner circumferential surface and an annular supporting surface. The inner circumferential surface corresponds to the outer circumferential surface of the folding reflective lens 111, and the annular supporting surface corresponds to the first reflecting surface 111b. The folding reflective lens 111 is precisely positioned in the structural member through its shape.

[0219] The lens group 112 can be installed on the above-mentioned structural member, and the active alignment (AA) process can be used to achieve the coincidence of the axes of the catadioptric lens 111 and the lens group 112. The optical lens 1121 can be installed in the lens barrel 1122, and the lens barrel 1122 is installed at a predetermined position to facilitate the positioning and assembly of the lens group 112.

[0220] There are a variety of optional implementations for setting the light folding element 113. The light folding element 113 can be a trapezoidal prism, a parallelogram prism, a triangular prism, or a combination of multiple reflectors, and can be set as needed.

[0221] In some embodiments, see Figure 4 , Figure 5 The light folding member 113 is a trapezoidal prism, and has a third transmission surface 113a and a fourth transmission surface 113b. The third transmission surface 113a and the fourth transmission surface 113b can be located on the same side of the trapezoidal prism, and the lens group 112 and the image sensor 120 are arranged adjacent to each other. The light emitted by the lens group 112 enters from the third transmission surface 113a of the light folding member 113, and after multiple reflections, is emitted from the fourth transmission surface 113b to the image sensor 120. The light folding member 113 can realize light folding, so that the camera module 100 occupies a smaller space.

[0222] For example, see Figure 5The shape of the trapezoidal prism can be an isosceles trapezoid, and the length of the lower base of the isosceles trapezoid is greater than the length of the upper base. The trapezoidal prism has a third transmission surface 113a, a third reflection surface 113c, a fourth reflection surface 113d, a fifth reflection surface 113e and a fourth transmission surface 113b. The third transmission surface 113a, the fourth reflection surface 113d and the fourth transmission surface 113b can be coplanar and located at the lower base of the isosceles trapezoid. The third reflection surface 113c and the fifth reflection surface 113e are respectively located at the two waist positions of the isosceles trapezoid. 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 photosensitive surface of the image sensor 120. The light emitted from the lens group 112 enters the first transmission surface 111 a , is reflected by the third reflection surface 113 c , the fourth reflection surface 113 d , and the fifth reflection surface 113 e in sequence, and then is emitted from the fourth transmission surface 113 b to the image sensor 120 .

[0223] Exemplarily, the shape of the trapezoidal prism can be an isosceles trapezoid, and the length of the lower base of the isosceles trapezoid is greater than the length of the upper base. The trapezoidal prism has a third transmission surface, a third reflection surface, a fourth reflection surface, a fifth reflection surface, a sixth reflection surface, a seventh reflection surface and a fourth transmission surface 113b. The third transmission surface, the fourth reflection surface, the sixth reflection surface and the fourth transmission surface can be coplanarly arranged and located at the lower base of the isosceles trapezoid. The fifth reflection surface is located at the upper base of the isosceles trapezoid. The third reflection surface and the seventh reflection surface are respectively located at the two waist positions of the isosceles trapezoid. 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 photosensitive surface of the image sensor 120. The light emitted by the lens group 112 enters the first transmission surface 111a, and after being reflected by the third reflection surface to the seventh reflection surface in sequence, it is emitted from the fourth transmission surface 113b to the image sensor 120.

[0224] In other embodiments, the light folding member 113 may include a plurality of reflectors, each of which has a reflective surface, and the plurality of reflectors are arranged at predetermined positions and angles, so that incident light in a predetermined direction can be reflected by the plurality of reflectors and output outgoing light in a predetermined direction. The plurality of reflectors may be arranged in the form of a trapezoidal prism, a parallelogram prism, a triangular prism, etc.

[0225] The following describes a first embodiment of the camera module 100. Figure 3 , Figure 4 , Figure 7 The focus motor 130 drives the catadioptric lens 111 and the lens group 112 to move to achieve focusing, and the anti-shake motor 140 drives the image sensor 120 to move to achieve optical image stabilization.

[0226] In some embodiments, see Figure 4 , Figure 7 , Figure 8, the optical axis A2 of the lens group 112 coincides with the optical axis A1 of the folding lens 111, and the camera module 100 also includes a first carrier 151 and a first base 152. The folding lens 111 and the lens group 112 are both arranged on the first carrier 151, and the two remain relatively stationary. The first carrier 151 is slidably mounted on the first base 152 along the direction of the optical axis A2 of the lens group 112; the focus motor 130 is used to drive the first carrier 151 to move relative to the first base 152. The first carrier 151 is driven by the focus motor 130 to move along the optical axis A2 of the lens group 112, and then the folding lens 111 and the lens group 112 are driven to move along the optical axis, so as to adjust the distance between the optical center of the optical lens 110 and the image sensor 120 to achieve focusing.

[0227] For example, see Figure 4 , Figure 7 The first base 152 includes a seat 1521 and a cover 1522. The folding lens 111 and the lens group 112 can be arranged on the seat 1521. The cover 1522 is connected to the seat 1521. The cover 1522 can surround most of the area of ​​the first carrier 151 to protect the first carrier 151. The cover 1522 has an opening 1522a, and the object side surface 111e of the folding lens 111 is exposed at the opening 1522a. The flange of the opening 1522a of the cover 1522 cooperates with the limiting portion 1513 of the first carrier 151 to limit the movement range of the first carrier 151 and prevent the first carrier 151 from slipping out of the opening 1522a. The seat 1521 has a through hole 1521a, and one end of the first carrier 151 can be inserted into the through hole 1521a. The lens group 112 is assembled at the through hole 1521a. The first carrier 151 has a first opening 151 a and a second opening 151 b opposite to each other. The object side surface 111 e of the folding lens 111 is exposed at the first opening 1641 a , and one end of the lens group 112 can be aligned with the second opening 1641 b .

[0228] For example, see Figure 4 , Fig. 9 , Fig.10 The focus motor 130 is a moving magnet 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 first carrier 151, and the focus coil 132 is disposed on the first base 152. The focus magnet 131 and the focus coil 132 are disposed facing each other, and the two cooperate to generate a Lorentz force to drive the first carrier 151 to move along the optical axis. The first carrier 151 has a positioning groove 1514, and the focus magnet 131 can be positioned and installed in the positioning groove 1514. The first base 152 has a positioning portion 1521b, and the focus coil 132 can be sleeved on the positioning portion 1521b.

[0229] In some embodiments, see Figure 4In the case where the catadioptric lens 111 and the lens group 112 are both arranged on the first carrier 151, the focus motor 130, the lens group 112 and the image sensor 120 are arranged in sequence along the first direction X, the focus motor 130 is located on one side of the first carrier 151 along the first direction X, and the focus motor 130 is arranged at a position of the lens group 112 away from the image sensor 120. By occupying a certain space, the focus motor 130 can generate a certain Lorentz force to drive the lens group 112 and the catadioptric lens 111 to move.

[0230] Exemplarily, the diameter of the lens group 112 is smaller than the diameter of the catadioptric lens 111. The shape of the first carrier 151 can be set according to the outer contours of the catadioptric lens 111 and the lens group 112. The focus motor 130 can be located at a position of the first carrier 151 away from the catadioptric lens 111 and arranged adjacent to the lens group 112, which can better utilize the surrounding space of the first carrier 151 and make the size of the camera module 100 in the first direction X smaller.

[0231] In some embodiments, see Figures 8 to 10 A support member 153 is provided on one side of the first base 152 close to the focus motor 130, and the first carrier 151 and the support member 153 are slidably matched. The camera module 100 further includes a constraint component 154, which is used to press the first carrier 151 toward the support member 153 along the first direction X. The first carrier 151 can be slidably installed on the first base 152 along a predetermined direction, and the constraint component 154 keeps the first carrier 151 and the support member 153 in a squeezing trend, thereby reducing the overturning of the first carrier 151 and improving the movement reliability of the first carrier 151.

[0232] Exemplarily, the support member 153 may be a sliding column, which extends along the moving direction of the first carrier 151 and is mounted on the first base 152. The first carrier 151 has slots 1511 and mating surfaces 1512 arranged at intervals. One of the sliding columns is slidably matched with the wall of the slot 1511, and the other sliding column is slidably matched with the mating surface 1512, so that the first carrier 151 can be slidably mounted on the first base 152 along a predetermined direction.

[0233] In some embodiments, see Figures 8 to 10 The restraining assembly 154 includes a first magnetic member 1541 and a second magnetic member 1542 . The first magnetic member 1541 is disposed on the first carrier 151 , and the second magnetic member 1542 is disposed on the first base 152 . The first magnetic member 1541 and the second magnetic member 1542 are arranged at intervals along the first direction X. Through the magnetic attraction of the first magnetic member 1541 and the second magnetic member 1542 , the first carrier 151 is pressed toward 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 .

[0234] One of the first magnetic member 1541 and the second magnetic member 1542 may be a magnet, and the other may be a magnetic conductive member. The magnetic conductive member may be a structure made of pure iron, low carbon steel, silicon steel, or the like. Alternatively, the first magnetic member 1541 and the second magnetic member 1542 may be magnets that can attract each other.

[0235] The first magnetic member 1541 may be fixed at a corresponding slot of the first carrier 151 . The second magnetic member 1542 may be fixed at a corresponding slot of the first base 152 .

[0236] Exemplarily, the focus motor 130 is a voice coil motor, the first magnetic member 1541 is a magnet, and the second magnetic member 1542 is a magnetic conductive member. The first magnetic member 1541 and the focus magnet 131 of the focus motor 130 need to be avoided to reduce magnetic interference to the focus motor 130. The first magnetic member 1541 and the focus motor 130 are arranged along the optical axis A2 direction of the lens group 112. The first base 152 is provided with two support members 153 at intervals, and the first base 152 is provided with two support members 153, and each support member 153 is adjacent to a second magnetic member 1542. The first carrier 151 is correspondingly provided with two first magnetic members 1541. Through the two groups of first magnetic members 1541 and second magnetic members 1542, the first carrier 151 is reliably maintained on the first base 152 and is not easy to overturn.

[0237] In some embodiments, see Figures 8 to 10 The focus motor 130 includes a focus magnet 131 and a focus coil 132. One of the focus magnet 131 and the focus coil 132 is disposed on the first carrier 151, and the other is disposed on the first base 152. The focus magnet 131 and the focus coil 132 are disposed facing each other along the first direction X. The focus magnet 131 and the focus coil 132 cooperate to generate an electromagnetic driving force required for the first carrier 151 to move. The first magnetic member 1541 is a magnet, and the second magnetic member 1542 is a magnetic conductive member. The projection of at least one second magnetic member 1542a on a vertical plane in the first direction X intersects with the projection of the focus motor 130 on the vertical plane in the first direction X. There is a magnetic attraction between the first magnetic member 1541 and the second magnetic member 1542, and there is also a magnetic attraction between the focusing magnet 131 and at least one second magnetic member 1542a. By increasing the magnetic attraction, the first carrier 151 can be reliably pressed toward the first base 152 along the first direction X, so that the first carrier 151 is not easily overturned.

[0238] For example, see Figures 8 to 10 The second magnetic member 1542a is a magnetic conductive member, wherein one second magnetic member 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 to generate magnetic attraction between the second magnetic member 1542a and the focusing magnet 131.

[0239] For example, see Figures 11 to 13 , the first magnetic component 1541 is a magnet, and the second magnetic component 1542 / 1542a is a magnetic conductive component. The second magnetic component 1542a is installed on the first base 152. The second magnetic component 1542a can be H-shaped or U-shaped. The second magnetic component 1542a includes two vertical arms and a horizontal arm, and the two ends of the horizontal arm are respectively connected to the two vertical arms. The two vertical arms are respectively arranged in a one-to-one correspondence with the two first magnetic components 1541 of the first carrier 151, and a magnetic attraction is formed between the vertical arms and the first magnetic components 1541. The horizontal arm and the focusing magnet 131 are correspondingly arranged along the first direction X to form a magnetic attraction. Thereby, a larger force is formed between the first carrier 151 and the first base 152.

[0240] In some embodiments, see Figure 3 , Figure 4 The side of the first base 152 away from the focus motor 130 along the first direction X is an arc surface 152a, and the side of the first base 152 close to the focus motor 130 along the first direction X is a flat surface 152b. Figure 2 , the camera module 100 is assembled in the device housing 200 of the electronic device 10, such as the decorative shell 211 of the camera module 100, the arc surface 152a of the first base 152 can be arranged facing the edge of the opening 2111 of the decorative shell 211, and the plane 152b of the first base 152 can be away from the edge of the opening 2111 of the decorative shell 211, so that the focus motor 130 does not occupy too much space of the decorative shell 211. The arc surface 152a and the plane 152b can be formed on the outer peripheral surface of the cover 1522.

[0241] In some embodiments, see Figure 7 , Fig.14 , Fig.15 The camera module 100 further includes a second carrier 155 and a second base 156. The image sensor 120 is disposed on the second carrier 155. The second carrier 155 can move on a first plane relative to the second base 156. The anti-shake motor 140 is used to drive the second carrier 155 to move on the first plane. The first plane is parallel to the photosensitive surface of the image sensor 120. The anti-shake motor 140 drives the second carrier 155 to move, and then drives the image sensor 120 to translate and / or rotate on the first plane, so that the image sensor 120 can be compensated for motion and optical image stabilization can be achieved.

[0242] The focus motor 130 drives the catadioptric lens 111 and the lens group 112 to move to achieve focusing, and the anti-shake motor 140 drives the image sensor 120 to move on the first plane to achieve optical anti-shake. The anti-shake motor 140 and the focus motor 130 are separately arranged, and the combination of Figure 3, so that the shoulder height D1 of the camera module 100 is relatively low. In the scenario of the camera module 100 with a long focal length, the image sensor 120 is driven to move by the anti-shake motor 140 instead of driving the catadioptric lens 111 and the lens group 112 to move. The anti-shake motor 140 has a small load and good reliability.

[0243] In some embodiments, see Figure 3 , Figure 7 The second base 156 is provided with a first shell 1563 and a second shell 1564, the first shell 1563 and the second shell 1564 are connected, and the first shell 1563 and the second shell 1564 jointly surround the focus motor 130, the second carrier 155 and the image sensor 120 to protect these components.

[0244] In some embodiments, see Fig.14 , Fig.15 A first reed 157 is provided on the side of the second base 156 away from the image sensor 120, and a second reed 158 is provided on the second carrier 155. The first reed 157 and the second reed 158 are connected by a plurality of connecting wires 159, which can pass through the second base 156. The connecting wires 159 are used to suspend the second reed 158 on the first reed 157, and then suspend the second carrier 155 on the second base 156. The second carrier 155 can move relative to the second base 156 within a certain range, so that the anti-shake motor 140 can drive the second carrier 155 and the image sensor 120 to move relative to the second base 156.

[0245] In some embodiments, see Fig.15 The first reed 157 may include a frame portion 1571 and a winding portion 1572, and each of the four corners of the frame portion 1571 is provided with a winding portion 1572. The frame portion 1571 may be roughly C-shaped or other shapes. The winding portion 1572 may be S-shaped or W-shaped or other shapes. The number of the second reeds 158 may be two. The two ends of each second reed 158 are arranged in a one-to-one correspondence with the two winding portions 1572, and each winding portion 1572 is connected to the end of the second reed 158 of the corresponding winding portion 1572 by a connecting wire 159.

[0246] In some embodiments, see Fig.14 (a) Fig.15 The second base 156 has a plurality of retaining walls 1561, which enclose a receiving cavity 1562, and the second carrier 155 is located in the receiving cavity 1562. An anti-collision portion 1551 is provided at a corner of the second carrier 155. When the second carrier 155 moves relative to the second base 156, the anti-collision portion 1551 of the second carrier 155 can contact the retaining wall 1561 of the second base 156, thereby protecting the second carrier 155.

[0247] In some embodiments, see Fig.15 , Fig.16 The anti-shake motor 140 includes a first anti-shake magnet 141, a first anti-shake coil 142, a second anti-shake magnet 143, a second anti-shake coil 144, a third anti-shake magnet 145 and a third anti-shake coil 146. The first anti-shake magnet 141, the second anti-shake magnet 143 and the third anti-shake magnet 145 are all arranged on the second base 156. The first anti-shake coil 142, the second anti-shake coil 144 and the third anti-shake coil 146 are all arranged on the second carrier 155. The first anti-shake magnet 141 and the first anti-shake coil 142 are arranged opposite to each other, the second anti-shake magnet 143 and the second anti-shake coil 144 are arranged opposite to each other, and the third anti-shake magnet 145 and the third anti-shake coil 146 are arranged opposite to each other. The anti-shake motor 140 adopts a dynamic voice coil motor. Through three sets of anti-shake coils and anti-shake magnets, the second carrier 155 can be translated in any direction on the first plane and rotated on the first plane.

[0248] The first anti-shake magnet 141 , the second anti-shake magnet 143 and the third anti-shake magnet 145 may be respectively disposed in corresponding slots of the second base 156 .

[0249] Exemplarily, the first anti-shake coil 142 extends along the first direction X, and the first anti-shake coil 142 and the second carrier 155 are aligned at the center of the first direction X. The first anti-shake magnet 141 and the first anti-shake coil 142 cooperate to generate a Lorentz force along the second direction Y to drive the second carrier 155 to move along the second direction Y. The first direction X and the second direction Y are perpendicular to each other.

[0250] The second anti-shake coil 144 extends along the second direction Y, and the second anti-shake coil 144 and the second carrier 155 are aligned at the center of the second direction Y. The second anti-shake magnet 143 and the second anti-shake coil 144 cooperate to generate a Lorentz force along the first direction X to drive the second carrier 155 to move along the first direction X.

[0251] The first anti-shake magnet 141 cooperates with the first anti-shake coil 142, and the second anti-shake magnet 143 cooperates with the second anti-shake coil 144, so that the second carrier 155 can be translated in any direction on the first plane. The first direction X and the second direction Y are both parallel to the first plane.

[0252] The third anti-shake magnet 145 and the third anti-shake coil 146 are respectively distributed at the center of the first direction X, and the third anti-shake magnet 145 and the third anti-shake coil 146 are respectively distributed at the center of the second direction Y. The third anti-shake magnet 145 and the third anti-shake coil 146 cooperate to generate a Lorentz force torque on the first plane to drive the second carrier 155 to rotate a predetermined angle on the first plane.

[0253] In some embodiments, see Fig.15, Fig.16 The image sensor 120 has four sides 120a, and the first anti-shake coil 142, the second anti-shake coil 144 and the third anti-shake coil 146 are respectively located outside three of the sides 120a; the lens group 112 or the focus motor 130 is located outside another side 120a. The three groups of anti-shake coils and the focus motor 130 in the anti-shake motor 140 correspond to the four sides 120a of the image sensor 120, respectively, and the space around the optical lens 110 is fully utilized to arrange the focus motor 130 and the anti-shake motor 140, so that the size of the camera module 100 in the direction of the optical axis A2 of the lens group 112 is small.

[0254] In some embodiments, see Figure 7 , Fig. 9 The camera module 100 further includes a first carrier 151 and a first base 152. The first base 152 is provided with a first conductive portion 161. The first conductive portion 161 is electrically connected to the focus motor 130. Fig.14 , the second carrier 155 is connected with a first flexible board 162, and the first flexible board 162 is electrically connected to the electrical devices on the second carrier 155; the camera module 100 also includes a first circuit board 163, and the first circuit board 163 is electrically connected to the first conductive part 161 and the first flexible board 162 respectively. The control signal and the electric energy are transmitted to the first conductive part 161 and the first flexible board 162 through the first circuit board 163. The control signal and the electric energy are transmitted to the focus motor 130 of the first base 152 by the first conductive part 161 to drive the focus motor 130 to work. The control signal and the electric energy are transmitted to the electrical devices of the second carrier 155 by the first flexible board 162, and the electrical devices may be the image sensor 120 and the anti-shake motor 140, to drive the electrical devices to work.

[0255] The first conductive part 161 may be a conductor or a flexible board. The conductor and the first base 152 may be molded by insert injection molding, and the metal conductor is placed in an injection mold to mold the first base 152, so that the conductor is embedded in the first base 152. The first circuit board 163 may be electrically connected to the first conductive part 161 and the first flexible board 162 respectively by welding.

[0256] In some embodiments, see Fig.14 In (b) and (c), the second carrier 155 is connected to a pair of first flexible plates 162, each of which is bent, and the reaction force is small when the first carrier 151 moves on the first plane. The paired first flexible plates 162 are symmetrically arranged, and the symmetry plane passes through the center of the image sensor 120 and is parallel to the first direction X. It can realize the transmission of control signals and electric energy to the electrical devices of the second carrier 155, and can also make the force on the second carrier 155 symmetrical, so as to facilitate driving the second carrier 155 to move on the first plane.

[0257] In some embodiments, see Fig.14 In (c), one end of the first flexible board 162 is connected to the second carrier 155, and the other end is located on the side of the second base 156 away from the second carrier 155. The first flexible board 162 is bent at least three times outside the second base 156. The first flexible board 162 includes a first section 1621, a second section 1622 and a third section 1623 connected end to end in sequence. The first section 1621 is roughly L-shaped, and the plane where it is located is parallel to the XZ plane. The first section 1621 is connected to the second carrier 155. The second section 1622 extends along the second direction Y, and the plane where it is located is parallel to the YZ plane. The third section 1623 extends along the first direction X, and the plane where it is located is parallel to the XY plane. The third section 1623 is connected to the first circuit board 163. The two parts are located in different planes, that is, there is a bend between the two parts. The bending setting of the first flexible board 162 makes the reaction force smaller when the first carrier 151 moves on 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 both parallel to the first plane.

[0258] In some embodiments, see Figure 3 , Figure 4 , Figure 7 , further comprising a third base 164, the optical folding member 113 is mounted on the third base 164, and 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, so that the optical lens 110, the focus motor 130 and the anti-shake motor 140 are combined to form a modular camera module 100. The third base 164 has a slot, and the optical folding member 113 can be installed in the slot.

[0259] It can be understood that the optical folding element 113 in the first camera module 100 can be in the form of a trapezoidal prism, a parallelogram prism, or the like.

[0260] The following describes a second embodiment of the camera module 100. Figures 17 to 19 The folding lens 111 and the lens group 112 are grouped together, the focus motor 130 drives the lens group 112 to move to achieve focusing, and the anti-shake motor 140 drives the image sensor 120 to move to achieve optical image stabilization.

[0261] In some embodiments, see Figures 17 to 19, the optical axis A2 of the lens group 112 coincides with the optical axis A1 of the folding lens 111, and the camera module 100 also includes a first carrier 151 and a first base 152. The folding lens 111 and the lens group 112 are arranged in groups. The folding 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 slidably mounted on the first carrier 151 along the direction of the optical axis A2 of the lens group 112; the focus motor 130 is used to drive the first carrier 151 to move relative to the first base 152. The folding lens 111 and the lens group 112 are driven by the focus motor 130 to move along the optical axis, and the distance between the optical center of the optical lens 110 and the image sensor 120 is adjusted to achieve focusing. The focus motor 130 only needs to drive the lens group 112 and the first carrier 151 to move, and there is no need to drive the folding lens 111 to move. The load is small and the required driving force can be small.

[0262] The focus motor 130 drives the lens group 112 to move to achieve focusing, and the anti-shake motor 140 drives the image sensor 120 to move to achieve optical image stabilization, which can reduce the stroke and load weight of the focus motor 130, and the implementation difficulty of the focus motor 130 is relatively low.

[0263] In some embodiments, see Fig.18 , Fig.19 In the case where the lens group 112 is disposed on the first carrier 151, the focus motor 130 can be disposed on the periphery of the lens group 112. The focus motor 130 only needs to drive the lens group 112 and the first carrier 151, and the load is small. A focus motor 130 of a smaller size can provide a certain electromagnetic driving force to drive the first carrier 151 and the lens group 112 to move.

[0264] Exemplarily, a focusing coil 132 is disposed outside the first carrier 151, and two groups of focusing magnets 131 are disposed on the first base 152. The two groups of focusing magnets 131 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 cooperate with the focusing coil 132 to drive the first carrier 151 and the lens group 112 to move along the optical axis A2 to achieve focusing.

[0265] It can be understood that when the second camera module 100 is provided with the anti-shake motor 140 , reference can be made to the embodiment of providing the anti-shake motor 140 in the first camera module 100 .

[0266] 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 on the first seat 1641. The first seat 1641 has a first mouth 1641a, and the object side surface 111e of the catadioptric lens 111 is exposed at the first mouth 1641a. The first seat 1641 has a second mouth 1641b, and one end of the lens group 112 can be aligned with the second mouth 1641b. The optical folding member 113 is disposed on the second seat 1642. The first seat 1641 and the second seat 1642 are mounted on the third seat 1643, and the anti-shake motor 140 and the image sensor 120 are disposed on the third seat 1643. The optical lens 110, the focus motor 130, and the anti-shake motor 140 are combined to form a modular camera module 100. Different seats can be connected by bonding or other methods.

[0267] In some embodiments, see Fig.19 , Fig. 20 The light folding member 113 is a parallelogram prism, and has a third transmission surface 113a and a fourth transmission surface 113b. The third transmission surface 113a and the fourth transmission surface 113b are respectively located on two opposite sides of the parallelogram prism, and the lens group 112 and the image sensor 120 are located on two opposite sides of the parallelogram prism. The light emitted by the lens group 112 enters from the third transmission surface 113a of the light folding member 113, and after multiple reflections, it is emitted from the fourth transmission surface 113b to the image sensor 120. The light folding member 113 can realize light folding, so that the camera module 100 occupies a smaller space.

[0268] Exemplarily, a parallelogram prism is used, and the parallelogram 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 first side. The third reflection surface 113c is located at one of the second sides, and the sixth reflection surface 113f is located at the other second side. 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 photosensitive surface of the image sensor 120. The light emitted from the lens group 112 enters the first transmission surface 111a, is reflected by the third reflection surface 113c, the fourth reflection surface 113d, the fifth reflection surface 113e, and the sixth reflection surface 113f in sequence, and then is emitted from the fourth transmission surface 113b to the image sensor 120.

[0269] It is understandable that the optical folding element 113 in the second camera module 100 may also be in the form of a trapezoidal prism, and specific reference is made to the previous embodiment.

[0270] The following is an example of a third camera module 100. Figure 21 to Figure 23 The focus motor 130 drives the image sensor 120 to move to achieve focusing, and the anti-shake motor 140 drives the image sensor 120 to move to achieve optical image stabilization.

[0271] In some embodiments, the camera module 100 further includes a first bracket 171 and a second bracket 172, the image sensor 120 is mounted on the first bracket 171, and the first bracket 171 is slidably mounted on the second bracket 172 along the optical axis A5 direction of the image sensor 120; the focus motor 130 is used to drive the first bracket 171 to move along the optical axis A5 direction of the image sensor 120. The focus motor 130 drives the first bracket 171 to move along the optical axis A5 of the image sensor 120, and then drives the image sensor 120 to move along the optical axis A5, adjusts the distance between the optical center of the optical lens 110 and the image sensor 120, and achieves focusing.

[0272] Exemplary, combined Figure 24 to Figure 26 The focus motor 130 is a dynamic voice coil motor, and includes a focus magnet 131 and a focus coil 132. The focus magnet 131 is disposed on the second bracket 172, and the focus coil 132 is disposed on the first bracket 171. The focus magnet 131 and the focus coil 132 are disposed facing each other, and the two cooperate to generate a Lorentz force along the optical axis A5 direction to drive the first bracket 171 to move along the optical axis A5 direction.

[0273] In some embodiments, see Figure 24 to Figure 26 The second bracket 172 is provided with a sliding post 1721, and the first bracket 171 has a sliding groove 1711 and a matching surface 1712 arranged at intervals, wherein one sliding post 1721 is slidably matched with the wall of the sliding groove 1711, and the other sliding post is slidably matched with the matching surface 1712, so that the first bracket 171 can be slidably installed on the second bracket 172 along a predetermined direction.

[0274] In some embodiments, see Figure 24 to Figure 26The camera module 100 further includes a third bracket 173 and a fourth bracket 174. The third bracket 173 is located between the second bracket 172 and the fourth bracket 174. The second bracket 172 and the third bracket 173 are supported by a first ball 175, and the second bracket 172 can translate relative to the third bracket 173 along the first axis A6. The third bracket 173 and the fourth bracket 174 are supported by a second ball 176, and the third bracket 173 can translate relative to the fourth bracket 174 along the second axis A7. There is a predetermined angle between the first axis A6 and the second axis A7. The anti-shake motor 140 is used to drive the second bracket 172 to move relative to the fourth bracket 174 on the first plane, and the first axis A6 and the second axis A7 are parallel to the first plane. The first plane is parallel to the XY plane.

[0275] The second bracket 172, the third bracket 173 and the fourth bracket 174 are combined with the first ball 175 and the second ball 176. The third bracket 173 is located between the second bracket 172 and the fourth bracket 174, so that the second bracket 172 can be translated relative to the fourth bracket 174 in any direction on the first plane. The first bracket 171 is installed on the second bracket 172, and the image sensor 120 is installed on the first bracket 171, so that the image sensor 120 can be translated in any direction on the first plane. The anti-shake motor 140 drives the second bracket 172 and the first bracket 171 to move, that is, the anti-shake motor 140 drives the focus motor 130 to move, and then drives the image sensor 120 to translate on the first plane (the plane perpendicular to the optical axis of the image sensor 120), so that the image sensor 120 motion is compensated and optical anti-shake is achieved.

[0276] The focus motor 130 drives the image sensor 120 to move to achieve focusing, and the anti-shake motor 140 drives the image sensor 120 to move to achieve optical image stabilization. The focus motor 130 does not need to drive the catadioptric lens 111 and the lens group 112 with a large load to move. The structure of the focus motor 130 is relatively simple and the assembly difficulty is relatively low.

[0277] In some embodiments, see Fig.25 , Fig.26The third bracket 173 has a first guide groove 1731 on one side facing the second bracket 172, and the second bracket 172 has a second guide groove 1722 on one side facing the third bracket 173. The first guide groove 1731 and the second guide groove 1722 are arranged correspondingly and both extend in the direction of the first axis A6. The first ball 175 is arranged between the wall surface of the first guide groove 1731 and the wall surface of the second guide groove 1722. The second bracket 172 and the third bracket 173 are kept at a distance, and the first ball 175 is kept moving in the area defined by the first guide groove 1731 and the second guide groove 1722. The second bracket 172 can move relative to the third bracket 173 in the direction of the first axis A6, but cannot move in other directions. By arranging multiple groups of first guide grooves 1731, second guide grooves 1722 and first balls 175, the second bracket 172 can move smoothly.

[0278] The third bracket 173 has a third guide groove 1732 on one side facing the fourth bracket 174, and the fourth bracket 174 has a fourth guide groove 1741 on one side facing the third bracket 173. The third guide groove 1732 and the fourth guide groove 1741 are arranged correspondingly and both extend in the direction of the second axis A7. The second ball 176 is arranged between the wall surface of the third guide groove 1732 and the wall surface of the fourth guide groove 1741. The third bracket 173 and the fourth bracket 174 are kept at a distance, and the second ball 176 is kept moving in the area defined by the third guide groove 1732 and the fourth guide groove 1741. The third bracket 173 can move relative to the fourth bracket 174 in the direction of the second axis A7, but cannot move in other directions. By arranging multiple groups of the third guide groove 1732, the fourth guide groove 1741 and the second ball 176, the third bracket 173 can move smoothly.

[0279] The second bracket 172 can move relative to the third bracket 173 along the direction of the first axis A6, and the third bracket 173 can move relative to the fourth bracket 174 along the direction of the second axis A7, so that the second bracket 172 can translate relative to the fourth bracket 174 in any direction on the first plane.

[0280] In some embodiments, see Fig.25 , Fig.26The anti-shake motor 140 includes a first anti-shake magnet 141, a first anti-shake coil 142, a second anti-shake magnet 143 and a second anti-shake coil 144. The first anti-shake magnet 141 and the second anti-shake magnet 143 are both arranged on the second bracket 172, the first anti-shake coil 142 and the second anti-shake coil 144 are both arranged on the fourth bracket 174, the first anti-shake magnet 141 and the first anti-shake coil 142 are arranged facing each other, and the second anti-shake magnet 143 and the second anti-shake coil 144 are arranged facing each other. The anti-shake motor 140 adopts a moving magnet voice coil motor. Through two sets of anti-shake coils and anti-shake magnets, the second bracket 172 can be translated in any direction on the first plane relative to the fourth bracket 174.

[0281] The first anti-shake magnet 141 and the first anti-shake coil 142 may be respectively disposed in corresponding slots of the second bracket 172 .

[0282] Exemplarily, the first anti-shake coil 142 extends along the first direction X, and the first anti-shake coil 142 and the second bracket 172 are aligned at the center of the first direction X. The first anti-shake magnet 141 and the first anti-shake coil 142 cooperate to generate a Lorentz force along the second direction Y to drive the second bracket 172 to move along the second direction Y. The first direction X and the second direction Y are perpendicular to each other. The first direction X is parallel to the first axis A6, and the second direction Y is parallel to the second axis A7.

[0283] The second anti-shake coil 144 extends along the second direction Y, and the second anti-shake coil 144 and the second bracket 172 are respectively aligned at the center of the second direction Y. The second anti-shake magnet 143 and the second anti-shake coil 144 cooperate to generate a Lorentz force along the first direction X to drive the second bracket 172 to move along the first direction X.

[0284] The first anti-shake magnet 141 cooperates with the first anti-shake coil 142, and the second anti-shake magnet 143 cooperates with the second anti-shake coil 144, so that the second bracket 172 can be translated in any direction on the first plane. The first direction X and the second direction Y are both parallel to the first plane.

[0285] In some embodiments, see Fig.25 , Fig.26 The image sensor 120 has four side edges 120a, and the first anti-shake magnet 141 and the second anti-shake magnet 143 are respectively located outside two adjacent side edges 120a; Fig. 22 The focus motor 130 and the lens group 112 are respectively located outside the other two adjacent side edges 120a. The space around the optical lens 110 is fully utilized to arrange the focus motor 130 and the anti-shake motor 140, so that the camera module 100 occupies less space.

[0286] In some embodiments, see Fig.25 , Fig.26The third bracket 173 includes a first connecting arm 1733 and a second connecting arm 1734 connected to each other. The first connecting arm 1733 is located on the side of the first anti-shake magnet 141 away from the image sensor 120, and the second connecting arm 1734 is located on the side of the second anti-shake magnet 143 away from the image sensor 120. The first connecting arm 1733 and the second connecting arm 1734 can be arranged in an L shape, occupying a small space. The third bracket 173, combined with the first ball 175 and the second ball 176, can make the second bracket 172 translate relative to the third bracket 173 in any direction along the first plane. The first connecting arm 1733 can extend along the first direction X, and the second connecting arm 1734 can extend along the second direction Y.

[0287] When the second bracket 172, the third bracket 173 and the fourth bracket 174 are provided with the sliding groove and the ball, the first connecting arm 1733 is away from one end of the second connecting arm 1734, the second connecting arm 1734 is away from one end of the first connecting arm 1733, and the connecting position of the first connecting arm 1733 and the second connecting arm 1734 can be provided with a first guide groove 1731 and a third guide groove 1732 respectively. The first guide groove 1731 and the third guide groove 1732 are located on opposite sides of the third bracket 173. The second bracket 172 is provided with the second guide groove 1722 corresponding to the position of the first guide groove 1731, and the first ball 175 is provided at the first guide groove 1731 and the second guide groove 1722, so that the second bracket 172 can move smoothly relative to the third bracket 173. The fourth bracket 174 is provided with a fourth guide groove 1741 at a position corresponding to the third guide groove 1732 , and the second ball 176 is disposed at the third guide groove 1732 and the fourth guide groove 1741 , so that the third bracket 173 can move smoothly relative to the fourth bracket 174 .

[0288] In some embodiments, see Fig.24 , Fig.25 The first bracket 171 is connected to a pair of second flexible plates 181, and each second flexible plate 181 is bent so that the reaction force is small when the first bracket 171 and the image sensor 120 move. The paired second flexible plates 181 are arranged symmetrically, and the symmetry plane passes through the center of the image sensor 120 and is parallel to the second direction Y. It can realize the transmission of control signals and electric energy to the electrical components of the first bracket 171, and can also make the force of the first bracket 171 symmetrical, so as to facilitate driving the first bracket 171 to move in three directions.

[0289] In some embodiments, see Fig.24 , Fig.25, one end of the second flexible board 181 is electrically connected to the electrical device on the first bracket 171, and the other end is located on the side of the fourth bracket 174 away from the first bracket 171. The second flexible board 181 is bent at least five times. The second flexible board 181 includes a first section 1811, a second section 1812, a third section 1813, a fourth section 1814, a fifth section 1815 and a sixth section 1816 connected end to end in sequence. The first section 1811 extends along the first direction X, and the plane where it is located is parallel to the XY plane. The first section 1811 is connected to the first bracket 171. The second section 1812 extends along the second direction Y, and the plane where it is located is parallel to the YZ plane. The third section 1813 extends along the second direction Y, and the plane where it is located is parallel to the XY plane. The third section 1813 is located on the side of the fourth bracket 174 away from the first bracket 171. The fourth section 1814 is roughly L-shaped, and the plane where it is located is parallel to the YZ plane. The second section 1812 and the fourth section 1814 are coplanar. The fifth section 1815 extends along the first direction X, and the plane where it is located is parallel to the XZ plane. The sixth section 1816 extends along the second direction Y, and the plane where it is located is parallel to the XY plane. The sixth section 1816 is connected to the second circuit board 183. The two parts are located in different planes, that is, there is a bend between the two parts. The bending setting of the second flexible board 181 makes the reaction force smaller when the first bracket 171 and the image sensor 120 move. 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. The fourth bracket 174 has an avoidance groove 1744, and the third section 1813 can be arranged in the avoidance groove 1744 to reduce the size of the camera module 100 in the third direction Z.

[0290] In some embodiments, see Fig.25 The fourth bracket 174 is provided with a second conductive portion 182, and the second conductive portion 182 is electrically connected to the anti-shake motor 140; Fig.23 The camera module 100 further includes a second circuit board 183, which is electrically connected to the second conductive portion 182 and the second flexible board 181, respectively. The control signal and the electric energy are transmitted to the second conductive portion 182 and the second flexible board 181 through the second circuit board 183. The second conductive portion 182 transmits the control signal and the electric energy to the anti-shake motor 140 of the fourth bracket 174 to drive the anti-shake motor 140 to work. The second flexible board 181 transmits the control signal and the electric energy to the electrical components of the first bracket 171, such as the image sensor 120 and the focus motor 130, to drive the electrical components to work.

[0291] The second conductive part 182 may be a conductor or a flexible board. The conductor and the fourth bracket 174 may be molded by insert injection molding, and the metal conductor is placed in an injection mold to injection mold the fourth bracket 174, so that the conductor is embedded in the fourth bracket 174. The second circuit board 183 may be electrically connected to the second conductive part 182 and the second flexible board 181 respectively by welding.

[0292] In some embodiments, see Fig.25 , Fig.26 The fourth bracket 174 is provided with a protective shell 184, the first bracket 171, the second bracket 172 and the third bracket 173 are all located in the protective shell 184, and the second flexible board 181 is bent outside the protective shell 184. The protective shell 184 isolates the bracket and the second flexible board 181, reducing the interference and squeezing damage of the second flexible board 181 during the movement of the second bracket 172 relative to the fourth bracket 174.

[0293] In some embodiments, see Fig. 22 , Fig.23 The fourth bracket 174 is provided with a first shell 1742 and a second shell 1743, and the first shell 1742 and the second shell 1743 jointly surround the protective shell 184, the second flexible plate 181, and the components in the protective shell 184 (such as the first bracket 171, the second bracket 172, the third bracket 173, the focus motor 130, the anti-shake motor 140, and the image sensor 120) to protect these components.

[0294] In some embodiments, see Figure 21 to Figure 23 , the optical axis A2 of the lens group 112 coincides with the optical axis A1 of the catadioptric lens 111, the camera module 100 further comprises a base 185, the catadioptric lens 111, the lens group 112 and the optical folding member 113 are all disposed on the base 185, and the fourth bracket 174 is disposed on the base 185. The optical lens 110, the focus motor 130 and the anti-shake motor 140 are combined to form a modular camera module 100.

[0295] Exemplarily, the base 185 includes a first seat 1851 and a second seat 1852, and the catadioptric lens 111 and the lens group 112 are mounted in the first seat 1851. The optical folding member 113 is mounted in the second seat 1852. The first seat 1851 and the second seat 1852 are connected to realize the positioning and assembly of the catadioptric lens 111, the lens group 112 and the optical folding member 113. The focus motor 130 and the anti-shake motor 140 can be mounted in the second seat 1852. Different seats can be connected by bonding or other means. The first seat 1851 has a first mouth 1851a, and the object side surface 111e of the catadioptric lens 111 is exposed in the first mouth 1851a. The first seat 1851 has a second mouth 1851b, and one end of the lens group 112 can be aligned with the second mouth 1851b. The optical folding member 113 is arranged in the second seat 1642.

[0296] It can be understood that the optical folding element 113 in the third camera module 100 can be in the form of a trapezoidal prism, a parallelogram prism, etc., and specific reference is made to the previous embodiments.

[0297] The following is an introduction to a fourth embodiment of the camera module 100. Figure 27 to Figure 29 A light reflecting member 114 is disposed between the folding lens 111 and the lens group 112 , the lens group 112 is driven by the focus motor 130 to move to achieve focusing, and the image sensor 120 is driven by the anti-shake motor 140 to move to achieve optical anti-shake.

[0298] In some embodiments, see Figures 28 to 30 In the case where a light reflecting member 114 is provided between the folding and reflecting lens 111 and the lens group 112, the light reflecting member 114 is located on the image side of the folding and reflecting lens 111, and the light reflecting member 114 is used to fold the light emitted from the second transmission surface 111d to the lens group 112, and a predetermined angle is formed between the optical axis A2 of the lens group 112 and the optical axis A1 of the folding and reflecting lens 111. The optical axis A1 of the folding and reflecting lens 111 and the optical axis A2 of the lens group 112 may be perpendicular to each other or may not be perpendicular to each other. The light emitted from the folding and reflecting lens 111 is reflected by the light reflecting member 114 and then enters the lens group 112. The light reflecting member 114 may be a prism or a reflector.

[0299] Exemplarily, the light reflecting member 114 is a right-angle prism, and the optical axis A2 of the lens group 112 is perpendicular to the optical axis A1 of the folding lens 111 .

[0300] In some embodiments, see Figures 28 to 30 The light folding member 113 may be a triangular prism, and the light folding member 113 has a third transmission surface 113a and a fourth transmission surface 113b, and the third transmission surface 113a and the fourth transmission surface 113b are respectively located on two adjacent sides of the triangular prism. The light emitted from the lens group 112 enters from the third transmission surface 113a of the light folding member 113, and after multiple reflections, is emitted from the fourth transmission surface 113b to the image sensor 120. The light folding member 113 can realize light folding, so that the camera module 100 occupies less space.

[0301] Exemplarily, a triangular prism is used, and the triangular prism has a third transmission surface 113a, a third reflection surface 113c, a fourth reflection surface 113d and a fourth transmission surface 113b. The third reflection surface 113c and the fourth transmission surface 113b can be coplanar and located at one side of the triangle. The third transmission surface 113a and the fourth reflection surface 113d are respectively located at the other two sides of the triangle. A reflection layer can be provided on the fourth reflection surface 113d. 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 photosensitive surface of the image sensor 120. The light emitted by the lens group 112 enters the first transmission surface 111a, and after being reflected by the third reflection surface 113c and the fourth reflection surface 113d in sequence, it is emitted from the fourth transmission surface 113b to the image sensor 120.

[0302] In some embodiments, see Fig.28 , Fig.29, Fig.31 A light reflecting member 114 is provided between the folding and reflecting lens 111 and the lens group 112. The camera module 100 includes a first carrier 151 and a first base 152. The lens group 112 is provided on the first carrier 151. The first carrier 151 is slidably mounted on the first carrier 151 along the direction of the optical axis A2 of the lens group 112. The focus motor 130 is used to drive the first carrier 151 to move relative to the first base 152. The first carrier 151 is driven by the focus motor 130 to move along the optical axis A2 of the lens group 112, and then the lens group 112 is driven to move along the optical axis A2, so as to adjust the distance between the optical center of the optical lens 110 and the image sensor 120 and achieve focusing. Under the same volume or the same shoulder height D1, the stroke of the lens group 112 of the camera module 100 of this embodiment can be set to be larger, so as to achieve a larger equivalent focal length, such as 300 mm.

[0303] For example, see Fig.28 , Fig.31 The first base 152 includes a seat 1521 and a cover 1522. The cover 1522 is connected to the seat 1521. The seat 1521 and the cover 1522 can surround the first carrier 151 to protect the first carrier 151. The cover 1522 can limit the movement range of the first carrier 151.

[0304] For example, see Fig.31 The focus motor 130 is a moving magnet 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 first carrier 151, and the focus coil 132 is disposed on the first base 152. The focus magnet 131 and the focus coil 132 are disposed facing each other. The two cooperate to generate a Lorentz force to drive the first carrier 151 to move along the optical axis A2 direction of the lens group 112. The focus motors 130 are arranged in pairs and spaced apart. Fig.29 The arrangement direction of the focus motor 130, the optical axis A2 of the lens group 112, and the optical axis A1 of the folding lens 111 are perpendicular to each other, so that the shoulder height of the camera module 100 is small.

The first plane is parallel to the photosensitive surface of the image sensor 120. The anti-shake motor 140 drives the second carrier 155 to move, thereby driving the image sensor 120 to translate and / or rotate on a plane perpendicular to the optical axis, so that the image sensor 120 can be compensated for motion and optical image stabilization can be achieved.
