TECHNICAL FIELD

[0002] The present application relates to the technical field of shooting devices, in particular to a camera module and an electronic device. BACKGROUND

[0003] With the continuous development of portable electronic devices such as mobile phones, users have higher and higher requirements for the long-focus macro shooting performance of portable electronic devices. In order to meet the needs of users, long-focus macro camera modules have become an indispensable part of electronic devices. However, due to the unreasonable structure of the existing long-focus macro camera module, the movement stroke of the motor driving lens during focusing is large.

[0004] SUMMARY

[0005] The present application provides a camera module and an electronic device with a small movement stroke during focusing.

[0006] In a first aspect, the present application provides a camera module. The camera module comprises a motor, a first lens, a second lens, a prism assembly and an image sensor assembly, the first lens and the second lens are installed on the motor; the prism assembly comprises an incident surface and an exit surface, the incident surface of the prism assembly is arranged to face the first lens, and the exit surface of the prism is arranged to face the image sensor assembly; after the light enters the camera module, it passes through the second lens, the first lens and the incident surface of the prism assembly in sequence and then enters the prism assembly, the light is reflected multiple times inside the prism assembly and then is emitted from the exit surface of the prism assembly and imaged on the image sensor assembly; the motor comprises a base, a shake reduction driving mechanism, a shake reduction support, a focusing support and a focusing driving mechanism, the shake reduction support is movably connected to the base, and the focusing support is movably connected to the shake reduction support; the first lens is fixed to the shake reduction support, the second lens is fixed to the focusing support, the shake reduction driving mechanism is used to drive the shake reduction support to drive the first lens, the focusing support and the second lens to move relative to the base along a first direction and / or a second direction, and the focusing driving mechanism is used to drive the focusing support to drive the second lens to move relative to the shake reduction support along a third direction, so that the second lens is close to or away from the first lens, wherein the first direction, the second direction and the third direction are different from each other.

[0007] It can be understood that the motor can control the first lens and the second lens to move in the first direction and / or the second direction to achieve optical anti-shake. In this way, when the camera module collects ambient light, if the camera module is shaken in the first direction and / or the second direction due to external force, the motor can control the first lens and the second lens to move in the first direction and / or the second direction to offset the shaking distance of the first lens and the second lens in the first direction and / or the second direction, so as to avoid or reduce the positional bias of the first lens and the second lens caused by shaking. In other words, the camera module of the present application can control the first lens and the second lens to move in the first direction and / or the second direction by the motor to achieve optical image stabilization of the camera module and improve the imaging quality of the camera module.

[0008] It can be understood that when the camera module is working, the first lens remains stationary in the third direction, and the second lens moves in the third direction to achieve autofocus, and the structure of the camera module is reasonably arranged. In this way, the movement distance of the second lens in the third direction is the focusing stroke of the camera module. Since the movement distance of the second lens is small, the focusing stroke of the camera module is also small, and the space requirement of the camera module in the third direction is also small, which can realize the miniaturization of the camera module.

[0009] It can be understood that the group arrangement of the first lens and the second lens of the camera module can avoid the anti-shake image rotation problem of the camera module, and the user's focusing experience is better.

[0010] In a possible implementation, during the focusing process of the camera module from a long shot to a close shot, the first lens remains stationary in the third direction, and the second lens moves away from the first lens in the third direction, and the distance between the first lens and the second lens increases; during the focusing process of the camera module from a close shot to a long shot, the first lens remains stationary in the third direction, and the second lens moves towards the first lens in the third direction, and the distance between the first lens and the second lens decreases.

[0011] It can be understood that when the camera module switches to shooting in a long-focus state, the second lens moves towards the image side of the camera module in the third direction to change the focal length of the camera module, which can realize focusing and shooting of the camera module in the long-focus state.

[0012] It can be understood that when the camera module switches to shooting in a macro state, the second lens moves towards the object side of the camera module in the third direction to change the focal length of the camera module, which can realize focusing and shooting of the camera module in the macro state.

[0013] In a possible implementation, the anti-shake support includes a mounting hole, the focusing support includes a mounting space, and the mounting hole and the mounting space are oppositely arranged; the first lens is fixed in the mounting hole of the anti-shake support, and the second lens is fixed in the mounting space of the focusing support.

[0014] It can be understood that, by setting the mounting hole and the mounting space to be oppositely arranged, the optical axis of the first lens and the optical axis of the second lens are substantially parallel. Exemplarily, the optical axis directions of the first lens and the second lens can be substantially parallel to the third direction, that is, the optical axis directions of the first lens and the second lens can both be substantially parallel to the thickness direction of the electronic device, the diameters of the first lens and the second lens are not limited by the thickness of the electronic device, the lens does not need to be cut to a specific diameter range in the thickness direction of the electronic device, the first lens and the second lens are symmetrical in the second direction and the third direction, and the camera module has no imaging ST separation and poor resolution.

[0015] In a possible implementation, a fixing block is protruded from the hole wall of the mounting hole of the anti-shake support; and the first lens is fixed to the fixing block and at least partially located on the side of the fixing block facing the base.

[0016] It can be understood that, the first lens is fixedly connected to the fixing block to achieve fixed connection with the anti-shake support, and the connection with the anti-shake support is more reliable.

[0017] In a possible implementation, the mounting hole forms a first opening on the anti-shake support, and the first lens does not protrude out of the first opening.

[0018] It can be understood that, in the process of focusing of the second lens, since the first lens does not protrude out of the first opening, the first lens and the second lens will not collide, thereby avoiding damage to the first lens or the second lens.

[0019] In a possible implementation, the first lens has a negative optical power, and the second lens has a positive optical power.

[0020] It can be understood that, by reasonably configuring the optical powers of the first lens and the second lens and setting the first lens and the second lens to have opposite optical powers, focusing and macro focusing are facilitated, the focusing stroke is reduced, the focusing capability is improved, the overall image quality of a picture in close-range imaging of the camera module is improved, the light amount of the system is increased, macro imaging is promoted, and the difference in imaging quality between long-range shooting and close-range shooting is balanced, so that good picture quality is achieved when shooting objects at different distances, and the imaging clarity is high.

[0021] It can be understood that, when the first lens has a negative optical power and the second lens has a positive optical power, the second lens can be used for converging light beams, so that the diameter of the light beams entering the first lens is small, the aperture of the first lens is no longer the maximum limit of the light passing aperture, the miniaturization and large-aperture design of the camera module are facilitated, the light passing aperture is effectively increased, a small aperture number is achieved, and the focusing capability is enhanced, which is conducive to macro shooting.

[0022] In a possible implementation, the second lens includes a first lens and a second lens, the first lens includes a third lens, the first lens, the second lens and the third lens are arranged in sequence, the first lens has positive refractive power, the second lens has negative refractive power, and the third lens has negative refractive power.

[0023] It can be understood that, by reasonably configuring the refractive power of the first lens, the second lens and the third lens, the miniaturization, large aperture and long focus of the camera module can be achieved, the focusing process from a long shot to a close shot of the camera module can be implemented, and the imaging quality of the camera module can be improved.

[0024] In a possible implementation, the focal length f1 of the first lens of the camera module and the effective focal length EFL of the camera module satisfy: f1 / EFL > -1.

[0025] It can be understood that, by reasonably limiting the range of f1 / EFL, the aperture number can be reduced, the design of a large aperture can be achieved, the light aperture of the camera module can be improved, and the good imaging quality of the camera module can be ensured.

[0026] In a possible implementation, the focal length f2 of the second lens of the camera module and the effective focal length EFL of the camera module satisfy: f2 / EFL ≤ 0.9.

[0027] It can be understood that, by limiting the range of f2 / EFL, the camera module can balance the image quality difference between long shot and close shot under small assembly sensitivity, and more uniform image quality can be obtained.

[0028] It can be understood that, by reasonably limiting the ranges of f1 / EFL and f2 / EFL, the refractive power of the first lens and the second lens can be reasonably configured, the focusing stroke of the camera module can be shortened, the focusing ability of the camera module can be improved, the camera module can be used for shooting in a macro state, and good image quality and high imaging clarity can be obtained when shooting objects at different distances.

[0029] In a possible implementation, the second lens includes at least one lens with an Abbe number less than 40.

[0030] It can be understood that the second lens can include at least one lens with high dispersion, and by limiting the Abbe number of at least one lens in the second lens to be less than 40, the chromatic aberration in the camera module can be reduced, and the camera module can have good imaging quality.

[0031] In a possible implementation, the camera module satisfies: FOV < 50°, where FOV is the field of view of the camera module when the object distance is infinity.

[0032] It can be understood that, by setting the field of view of the camera module, the camera module can have a long focus characteristic.

[0033] In a possible implementation, the camera module satisfies: Fno < 3.6, where Fno is the F-number of the camera module.

[0034] It can be understood that the smaller the value of Fno of the camera module is, the larger the aperture of the camera module is; the larger the value of Fno of the camera module is, the smaller the aperture of the camera module is. By limiting the value of Fno of the camera module, the camera module has the characteristic of large aperture.

[0035] In a possible implementation, the motor further includes a guide support, a plurality of first connecting members, and a plurality of second connecting members. The guide support is located between the anti-shake support and the base. The guide support is connected to the base through the plurality of first connecting members, and is connected to the anti-shake support through the plurality of second connecting members, so that the relative movement direction of the anti-shake support and the guide support is different from the relative movement direction of the guide support and the base.

[0036] It can be understood that the guide support can ensure the connection reliability of the anti-shake support and the base, and can realize the functions of stable support and accurate guidance, to ensure the stability of the relative positions of the first anti-shake coil and the first anti-shake magnetic member and the relative positions of the second anti-shake coil and the second anti-shake magnetic member. The motor can realize accurate guidance in the optical anti-shaking process through the cooperation of the base, the first connecting members, the guide support, the second connecting members, and the anti-shake support, thereby solving the problem of excessive lens tilting in the optical anti-shaking process of the traditional motor, and making the optical anti-shaking movement of the camera module stable and reliable.

[0037] In a possible implementation, the base includes a plurality of first grooves, the guide support includes a plurality of second grooves and a plurality of third grooves, and the anti-shake support includes a plurality of fourth grooves. The plurality of first connecting members and the plurality of second grooves are one-to-one correspondingly arranged, at least part of the first connecting member is located in the first groove of the base, and at least part of the first connecting member is located in the second groove of the guide support. The plurality of second connecting members and the plurality of third grooves and the plurality of fourth grooves are one-to-one correspondingly arranged, at least part of the second connecting member is located in the third groove of the guide support, and at least part of the second connecting member is located in the fourth groove of the anti-shake support.

[0038] It can be understood that the first groove can limit and guide the first connecting member, and the first connecting member can move in the second groove in the second direction. Therefore, the guide support can also slide relative to the base in a direction parallel to the second direction. The third groove can limit and guide the second connecting member, and the second connecting member can move in the fourth groove in the first direction. Therefore, the anti-shake support can slide relative to the base in a direction parallel to the first direction.

[0039] In a possible implementation, the anti-shake support is movably connected to the base through a rolling member.

[0040] It can be understood that, compared with the scheme that the anti-shake support is movably connected to the base through the second connecting member, the guide support and the first connecting member, the scheme that the anti-shake support is movably connected to the base through the rolling member has a simpler structure, thereby realizing miniaturized arrangement of the motor and the camera module.

[0041] In a possible implementation, the base comprises a first rolling groove, and the anti-shake support comprises a second rolling groove; at least part of the rolling member is located in the first rolling groove of the base, and at least part of the rolling member is located in the second rolling groove of the anti-shake support.

[0042] It can be understood that the rolling member can roll in the first direction and / or the second direction in the first rolling groove, and the second rolling groove of the anti-shake support can limit the rolling member. It can be understood that the anti-shake support and the rolling member can move together in any direction on the -plane relative to the base, and the relative movement between the anti-shake support and the base can be more controllable.

[0043] In a possible implementation, the anti-shake driving mechanism comprises a first anti-shake coil, a first anti-shake magnetic member, a second anti-shake coil and a second anti-shake magnetic member; the first anti-shake coil and the second anti-shake coil are fixed to the base, and the first anti-shake magnetic member and the second anti-shake magnetic member are fixed to the anti-shake support; the first anti-shake coil is arranged to face the first anti-shake magnetic member, to drive the anti-shake support to move in the first direction relative to the base, and the second anti-shake coil is arranged to face the second anti-shake magnetic member, to drive the anti-shake support to move in the second direction relative to the base.

[0044] It can be understood that, under the driving of the first anti-shake coil, the first anti-shake magnetic member, the second anti-shake coil and the second anti-shake magnetic member, the anti-shake support can drive the first lens to move in the first direction and / or the second direction relative to the base, thereby realizing movement of the first lens on the -plane.

[0045] In a possible implementation, the anti-shake driving mechanism comprises a first anti-shake sensor, which is fixed to the base and located on the inner side of the first anti-shake coil, to detect the position change of the anti-shake support in the first direction; and the anti-shake driving mechanism comprises a second anti-shake sensor, which is fixed to the base and located on the inner side of the second anti-shake coil, to detect the position change of the anti-shake support in the second direction.

[0046] It can be understood that the first anti-shake sensor and the second anti-shake sensor can detect the position change of the anti-shake support, and the camera module can adjust the position of the anti-shake support according to the detection result, thereby achieving better optical anti-shake effect.

[0047] In a possible implementation, the motor further includes a focusing circuit board fixed to the anti-shake support; the focusing driving mechanism includes a focusing coil and a focusing magnetic piece, the focusing coil is fixed to the focusing circuit board, and the focusing magnetic piece is fixed to the focusing support, the focusing coil is arranged to face the focusing magnetic piece, and is used to drive the focusing support to move relative to the anti-shake support along the third direction.

[0048] It can be understood that the focusing coil and the focusing magnetic piece drive the focusing support to move along the third direction, thereby driving the second lens to move along the third direction, and thus realizing the auto-focusing of the camera module. It can be understood that the smaller distance change can realize the larger focal length change, which is beneficial to improve the focusing capability of the camera module. It can be understood that the second lens with a shorter focusing stroke can realize the auto-focusing of the motor in the macro state, thereby improving the imaging quality of the camera module in the macro state.

[0049] In a possible implementation, the incident surface and the exit surface are located on the same side of the prism assembly.

[0050] It can be understood that the light rays can realize at least three reflections in the prism assembly, and the camera module has a longer light path stroke, which is beneficial to the shooting of the camera module in the long-focus state.

[0051] In a possible implementation, the incident surface and the exit surface are located on different sides of the prism assembly.

[0052] It can be understood that the light rays can realize at least two reflections in the prism assembly, and the camera module has a longer light path stroke, which is more beneficial to the shooting of the camera module in the long-focus state.

[0053] In a possible implementation, the prism assembly includes a prism and a prism support, the prism is mounted on the prism support; the prism includes a first surface, a second surface, a first side surface and a second side surface, the first side surface and the second side surface connect the first surface and the second surface, and the first surface and the second surface are arranged back to back; the prism assembly further includes a light shield fixed to the first surface of the prism, and the light shield divides the first surface into the incident surface and the exit surface.

[0054] It can be understood that the light rays can be folded at least three times inside the prism after entering the prism. In this way, the light path stroke of the camera module is large, and the shooting in the long-focus state can be realized, thereby improving the imaging quality of the camera module in the long-focus state.

[0055] In a possible implementation, the image sensor assembly comprises an image sensor and a circuit board, the circuit board comprises a first board part, a second board part and a third board part, the second board part connects the first board part and the third board part, and the first board part and the third board part are oppositely and spacedly arranged; the image sensor is fixed to one side of the first board part of the circuit board facing the third board part and electrically connected to the circuit board; and the prism assembly is fixed to the third board part of the circuit board and at least partially located between the first board part and the third board part.

[0056] It can be understood that, by fixing the image sensor assembly and the prism assembly together and by making the exit surface of the prism assembly face the image sensor, the reflection path of the light in the prism assembly is long, the long-focus characteristic of the camera module is met, and the long-focus shooting performance of the camera module is improved.

[0057] In a possible implementation, the prism assembly comprises a prism and a prism support, and the prism is mounted on the prism support; the prism comprises a first surface, a second surface, a first side surface and a second side surface, the first side surface and the second side surface connect the first surface and the second surface, the first surface and the second surface are oppositely arranged, and the first side surface and the second side surface are oppositely arranged; a part of the first surface forms the entrance surface, and a part of the second surface forms the exit surface.

[0058] It can be understood that, after entering the prism, the light can be reflected at least four times in the prism. In this way, the light path of the camera module is long, the shooting in the long-focus state can be implemented, and the imaging quality of the camera module in the long-focus state is improved.

[0059] It can be understood that, compared with the scheme in which the entrance surface and the exit surface of the prism are located on the same surface, the scheme in which the entrance surface and the exit surface of the prism are located on different surfaces can make the light be reflected at least four times in the prism, can have a longer total light path length, and has higher imaging quality in the long-focus state.

[0060] In a second aspect, the present application provides an electronic device. The electronic device comprises a shell and the camera module described above, and the camera module is arranged in the shell.

[0061] It can be understood that, the electronic device has a reasonable structure, the optical image stabilization performance and the auto-focusing performance of the electronic device are both good when the electronic device is shooting, and the user experience is good. In addition, the focusing stroke of the camera module is short, the size requirement of the camera module in the thickness direction of the electronic device is small, and the thinness of the electronic device is facilitated.

[0120] For the convenience of understanding, the following will first explain and describe the English abbreviations and related technical terms involved in the embodiments of the present application.

[0121] Object side, with the lens as the boundary, the side where the object to be imaged is located is the object side.

[0122] Image side, with the lens as the boundary, the side where the image of the object to be imaged is located is the image side.

[0123] Object side surface, with the lens as the boundary, the side where the object to be imaged is located is the object side, and the surface of the lens close to the object side is called the object side surface, also known as the object plane.

[0124] Image side surface, with the lens as the boundary, the side where the image of the object to be imaged is located is the image side, and the surface of the lens close to the image side is called the image side surface, also known as the image plane.

[0125] Optical axis, a light ray perpendicular to the center of the ideal lens. When the light rays parallel to the optical axis enter the convex lens, the ideal convex lens should converge all the light rays to a point behind the lens. This point where all the light rays converge is called the focal point. When the light rays propagate along the optical axis, their transmission direction does not change.

[0126] Focal length, also known as focal length, is a measure of the convergence or divergence of light in an optical system. It refers to the vertical distance from the optical center of the lens or lens group to the focal plane when an infinite distant object passes through the lens or lens group to form a clear image on the focal plane. For thin lenses, the focal length is the distance from the lens center to the imaging plane. For thick lenses or lens groups, the focal length is equal to the effective focal length, which is the distance between the rear principal plane of the lens or lens group and the imaging plane.

[0127] Effective focal length (EFL), defined as the distance from the center of the camera module to the focal point.

[0128] Focal power, defined as the difference between the image-side and object-side convergence of the light beam, is the reciprocal of the focal length of the lens, which represents the ability of the optical system to bend light.

[0129] Positive focal power, also known as positive refractive power, indicates that the lens has a positive focal length and can converge light.

[0130] Negative focal power, also known as negative refractive power, indicates that the lens has a negative focal length and can diverge light.

[0131] Aperture, which is used to control the amount of light that passes through the lens into the body of the camera, is usually inside the lens.

[0132] F-number, also known as F-number, is the relative value (the reciprocal of the relative aperture) derived from the focal length of the lens / the diameter of the entrance pupil of the lens. The smaller the F-number, the more light enters in the same unit of time. The larger the F-number, the smaller the depth of field, and the background content of the photograph will be blurred, similar to the effect of a long focal length lens.

[0133] Field of view (FOV), in optical instruments, is the angle formed by the two edges of the maximum range of the object image that can pass through the lens of the optical instrument, with the lens as the vertex. The size of the field of view determines the range of the optical instrument's field of view. The larger the field of view, the larger the field of view, and the smaller the optical magnification.

[0134] Imaging height (IH), which represents half the diagonal length of the effective pixel area on the photosensitive chip, is also the radius of the imaging circle.

[0135] Abbe number (Abbe), also known as dispersion coefficient, is the ratio of the difference in refractive index of optical materials at different wavelengths, representing the degree of dispersion of the material.

[0136] Refractive index (Nd), defined as the absolute value of the ratio of the propagation speed of light in a material to the speed of light in a vacuum, is an indicator of the material's propagation speed and bending degree of light.

Among them, "fixed connection" refers to the relative position relationship of the connection and the connection. "Movable connection" refers to the relative movement of the connection and the connection. "Sliding connection" refers to the relative sliding of the connection and the connection. In addition, the integrated structure of two components obtained by one-piece forming process means that during the formation of one of the two components, the component is connected with the other component, and the two components are connected together by reprocessing (such as bonding, welding, buckling connection, screw connection) method. Component A and component B are relatively arranged, which can be that component A projects to projection C along the target direction, component B projects to projection D along the target direction, and projection C and projection D can at least mostly overlap.

For those skilled in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0140] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not intended to describe a particular order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a class, and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally means that the front and rear associated objects are in an "or" relationship.

[0142] FIG. 1 is a structural schematic diagram of an electronic device 1000 provided by an embodiment of the present application.

[0143] As shown in FIG. 1, the electronic device 1000 can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, a vehicle-mounted device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses, or a VR helmet, etc. The electronic device 1000 provided by the embodiments of the present application takes a mobile phone as an example for illustration.

[0144] FIG. 2 is a partial cross-sectional schematic diagram of the electronic device 1000 shown in FIG. 1 in an embodiment at A-A line.

[0145] As shown in FIGS. 1 and 2, in some embodiments, the electronic device 1000 can include a camera module 100, a housing 200, and a screen 300. The camera module 100 can be a rear camera module 100 or a front camera module 100. It can be understood that FIG. 1 and the related drawings below only schematically show some components included in the electronic device 1000, and the actual shape, actual size, actual position, and actual structure of these components are not limited by FIG. 1 and the drawings below. In addition, when the electronic device 1000 is some other form of device, the electronic device 1000 can also not include the screen 300.

[0146] It can be understood that, hereinafter, for the convenience of description, the camera module 100 is defined to have a first direction X, a second direction Y and a third direction Z, which are different from each other. For example, the first direction X can be a length direction of the camera module 100, the second direction Y can be a width direction of the camera module 100, the second direction Y is perpendicular to the first direction X, and the third direction Z can be a height direction of the camera module 100, the third direction Z is perpendicular to the first direction X and the second direction Y. In other embodiments, the coordinate system of the camera module 100 can be flexibly set according to actual needs.

[0147] As shown in FIGS. 1 and 2, in some embodiments, the screen 300 is mounted to the shell 200 and cooperates with the shell 200 to enclose an interior of the electronic device 1000. The interior of the electronic device 1000 can be used to place devices of the electronic device 1000, such as a battery, a receiver or a microphone, etc. The screen 300 can be a flat screen or a curved screen.

[0148] For example, the camera module 100 can be located in the interior of the electronic device 1000. The shell 200 has a light-transmitting portion 201. The shape of the light-transmitting portion 201 is not limited to the circular shape shown in FIG. 1, but can also be an elliptical shape or an irregular shape. Light outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting portion 201. The camera module 100 can collect the light entering the interior of the electronic device 1000. The light-transmitting portion 201 can be a light-transmitting hole or a transparent portion in the shell 200. The specific structure of the light-transmitting portion 201 is not limited herein.

[0149] FIG. 3 is a structural schematic diagram of the camera module 100 shown in FIG. 1 in an embodiment. FIG. 4 is a partially exploded schematic diagram of the camera module 100 shown in FIG. 3 in an embodiment.

[0150] As shown in FIGS. 3 and 4, the camera module 100 includes a motor 1, a first lens 2, a second lens 3, a prism assembly 4 and an image sensor assembly 5. It can be understood that the camera module 100 can also include fewer or more structures. For example, the camera module 100 can also include a variable aperture (not shown in the drawings).

[0151] In an embodiment, the first lens 2 and the second lens 3 can be mounted on the motor 1.

[0152] The motor 1 can control the first lens 2 and the second lens 3 to move along a plane perpendicular to the third direction Z (i.e., the X-Y plane) to achieve optical image stabilization. In this way, when the camera module 100 collects ambient light, if the electronic device 1000 is subject to external forces and moves in the X-Y plane, the motor 1 can control the first lens 2 and the second lens 3 to move in the X-Y plane to offset the movement of the first lens 2 and the second lens 3 in the X-Y plane, so as to avoid or reduce the positional deviation of the first lens 2 and the second lens 3 caused by the movement. In other words, the camera module 100 can control the first lens 2 and the second lens 3 to move in the X-Y plane by the motor 1 to achieve optical image stabilization (OIS) of the camera module 100, and improve the imaging quality of the camera module 100.

[0153] In addition, the motor 1 can also control the second lens 3 to move along the third direction Z to achieve auto focus (AF). It can be understood that, compared with the scheme that the motor 1 controls the first lens 2 and the second lens 3 to move along the third direction Z at the same time, the motor 1 of the embodiment can not need to control the first lens 2 to move along the third direction Z, so that the focusing stroke of the camera module 100 is shorter.

[0154] As shown in FIGS. 2 and 4, the motor 1 has a clearance space 1a. The clearance space 1a can connect the inside of the motor 1 to the outside of the motor 1.

[0155] As shown in FIGS. 2 and 4, the prism assembly 4 includes a prism 41 and a prism holder 42, and the prism 41 can be fixedly connected to the prism holder 42.

[0156] The prism 41 has an incident surface S7 and an exit surface S11. The incident surface S7 and the exit surface S11 of the prism 41 can be located on the same side of the prism 41. In other embodiments, the incident surface S7 and the exit surface S11 of the prism 41 can be located on different sides of the prism 41, respectively.

[0157] As shown in FIGS. 2 and 4, at least part of the prism assembly 4 can be located in the clearance space 1a of the motor 1. In this way, on the one hand, the prism assembly 4 can make better use of the clearance space 1a of the motor 1, and improve the space utilization of the motor 1. On the other hand, the prism assembly 4 and the motor are arranged more compactly, which is conducive to the miniaturization of the camera module 100. In addition, at least part of the motor 1 is arranged opposite the incident surface S7 of the prism 41, so that the light passing through the first lens 2 and the second lens 3 can enter the prism 41.

[0158] As shown in FIGS. 2-4, the image sensor assembly 5 is disposed opposite the exit surface S11 of the prism 41, such that light rays passing through the prism 41 can enter the image sensor assembly 5.

[0159] It can be understood that, for example, light rays enter the camera module 100 from the light-transmitting portion 201 of the electronic device 1000, pass through the second lens 3, the first lens 2, and the entrance surface S7 of the prism 41 in sequence, and then enter the interior of the prism 41. After at least three reflections in the interior of the prism 41, the light rays pass through the exit surface S11 of the prism 41 to reach the image sensor assembly 5, which converts image information carried by the light rays into electrical signals.

[0160] FIG. 5 is a partially exploded schematic view of the motor 1 shown in FIG. 4, according to an embodiment.

[0161] As shown in FIG. 5, for example, the motor 1 includes an anti-shake module 1b and a focusing module 1c.

The anti-shake driving mechanism 14 includes a first anti-shake coil 141, a first anti-shake magnetic member 142, a second anti-shake coil 143, and a second anti-shake magnetic member 144. The first anti-shake coil 141 and the first anti-shake magnetic member 142 are disposed in correspondence to form a set of driving mechanisms, and the second anti-shake coil 143 and the second anti-shake magnetic member 144 are disposed in correspondence to form another set of driving mechanisms. The number of the first connecting member 131 and the second connecting member 132 can each be multiple, for example, three in the present embodiment. The number of the third connecting member 133 can be multiple, for example, two in the present embodiment.

FIG. 19 is a partial cross-sectional view of the camera module 100 shown in FIG. 18 along the line C-C in an embodiment. FIG. 20 is a partial cross-sectional view of the camera module 100 shown in FIG. 18 along the line D-D in an embodiment.

[0209] As shown in FIGS. 18-20, the anti-shake bracket 16 can be movably connected to the base 11 through the guide bracket 15, and the anti-shake bracket 16 can be located on the side of the guide bracket 15 away from the base 11. The three guide blocks 151 of the guide bracket 15 are located between the anti-shake bracket 16 and the base 11, the third groove 1514 of the guide bracket 15 is provided corresponding to the three fourth grooves 164 of the anti-shake bracket 16, and the second connecting member 132 mounted in the third groove 1514 can be at least partially embedded in the fourth groove 164. At this time, the anti-shake bracket 16 is connected to the three guide blocks 151 of the guide bracket 15 through the plurality of second connecting members 132.

[0210] It can be understood that the guide bracket 15 can ensure the connection reliability of the anti-shake bracket 16 and the base 11, and can realize the functions of stable support and accurate guidance, thereby ensuring the stability of the relative positions of the first anti-shake coil 141 and the first anti-shake magnetic member 142 and the relative positions of the second anti-shake coil 143 and the second anti-shake magnetic member 144. The cooperation of the base 11, the first connecting member 131, the guide bracket 15, the second connecting member 132 and the anti-shake bracket 16 can realize accurate guidance during optical anti-shake, thereby solving the problem of excessive lens tilt in the conventional motor optical anti-shake, and making the optical anti-shake movement of the camera module 100 stable and reliable.

[0211] Exemplarily, the plurality of first connecting members 131 are located in the first groove 113, the plurality of second connecting members 132 are located in the fourth groove 164 whose extension direction is parallel to the first direction X, and the anti-shake bracket 16 can move relative to the base 11 in a direction perpendicular to the third direction Z (i.e., the X-Y plane). In this way, the relative movement direction of the anti-shake bracket 16 and the guide bracket 15 is different from the relative movement direction of the guide bracket 15 and the base.

[0212] As shown in FIGS. 18-20, the first lens 2 can be fixedly connected with the anti-shake bracket 16.

[0213] For example, the first lens 2 can be located in the mounting hole 16a of the anti-shake bracket 16, the first lens 2 can be fixed to the fixed block 161a, and the first lens 2 does not protrude out of the first opening 162a. In an embodiment, a part of the first lens 2 can be located on the side of the fixed block 161a facing the base 11, and is fixedly connected to the surface of the fixed block 161a facing the base 11. In other embodiments, the connection position of the first lens 2 and the anti-shake bracket 16 is not specifically limited.

[0214] It can be understood that, in the process of focusing of the second lens 3, since the first lens 2 does not protrude out of the first opening 162a, no collision will occur between the first lens 2 and the second lens 3, thereby avoiding damage to the first lens 2 or the second lens 3.

[0215] It can be understood that, the first lens 2 is fixedly connected to the fixed block 161a to achieve fixed connection with the anti-shake bracket 16, and the connection with the anti-shake bracket 16 is more reliable.

[0216] For example, the first anti-shake coil 141 and the first anti-shake magnetic member 142 are arranged in the third direction Z, the first anti-shake coil 141 is arranged to face the first anti-shake magnetic member 142, and is used to drive the anti-shake bracket 16 and the first lens 2 to move relative to the base 11 along the first direction X. Wherein, the first anti-shake coil 141 is arranged to face the first anti-shake magnetic member 142, which means that the winding plane of the first anti-shake coil 141 faces the first anti-shake magnetic member 142. For example, the winding plane of the first anti-shake coil 141 can be arranged parallel to the X-Y plane.

[0217] For example, the first anti-shake sensor 145 can be used to detect the position change of the anti-shake bracket 16 in the first direction X.

[0218] For example, the second anti-shake coil 143 and the second anti-shake magnetic member 144 are arranged in the third direction Z, the second anti-shake coil 143 is arranged to face the second anti-shake magnetic member 144, and is used to drive the anti-shake bracket 16 and the first lens 2 to move relative to the base 11 along the second direction Y. Wherein, the second anti-shake coil 143 is arranged to face the second anti-shake magnetic member 144, which means that the winding plane of the second anti-shake coil 143 faces the second anti-shake magnetic member 144. For example, the winding plane of the second anti-shake coil 143 can be arranged parallel to the X-Y plane.

[0219] For example, the second anti-shake sensor 146 (see FIG. 12) can be used to detect the position change of the anti-shake bracket 16 in the second direction Y.

[0220] It can be understood that the first anti-shake sensor 145 and the second anti-shake sensor 146 can detect the position change of the anti-shake holder 16, and the camera module 100 can adjust the position of the anti-shake holder 16 according to the detection result, so as to achieve better optical anti-shake effect.

[0221] It can be understood that under the driving of the first anti-shake coil 141, the first anti-shake magnetic member 142, the second anti-shake coil 143 and the second anti-shake magnetic member 144, the anti-shake holder 16 can drive the first lens 2 to move relative to the base 11 along the first direction X and / or the second direction Y, so as to realize the movement of the first lens 2 in the X-Y plane.

[0222] It can be understood that the direction in which the first anti-shake coil 141 and the first anti-shake magnetic member 142 drive the anti-shake holder 16 and the first lens 2 to move can be perpendicular to the direction in which the second anti-shake coil 143 and the second anti-shake magnetic member 144 drive the anti-shake holder 16 and the first lens 2 to move. In other embodiments, the direction in which the first anti-shake coil 141 and the first anti-shake magnetic member 142 drive the anti-shake holder 16 to move can also intersect but not be perpendicular to the direction in which the second anti-shake coil 143 and the second anti-shake magnetic member 144 drive the anti-shake holder 16 to move.

[0223] It can be understood that under the action of the first anti-shake coil 141, the first anti-shake magnetic member 142, the second anti-shake coil 143 and the second anti-shake magnetic member 144, the anti-shake holder 16 can drive the first lens 2 to move relative to the base 11 in a direction perpendicular to the third direction Z (i.e., the X-Y plane). Based on the two groups of driving mechanisms of the first anti-shake coil 141 and the first anti-shake magnetic member 142, the second anti-shake coil 143 and the second anti-shake magnetic member 144, the anti-shake holder 16 and the first lens 2 can realize large-stroke movement in the X-Y plane.

[0224] FIG. 21 is a structural enlarged schematic view of the focusing circuit board 23 shown in FIG. 5 from another angle.

[0225] As shown in FIG. 21, the focusing circuit board 23 may, for example, be substantially in the shape of a "mouth" with a notch. The outer side of at least part of the focusing circuit board 23 is provided with a reinforcing plate.

[0226] For example, the focusing circuit board 23 includes a first fixed part 231 and a second fixed part 232. The first fixed part 231 and the second fixed part 232 can be located on both sides of the notch.

[0227] FIG. 22 is a partial structural assembly view of the motor 1 shown in FIG. 5 in an embodiment.

[0228] Referring to FIG. 22, and in combination with FIG. 14, the focusing circuit board 23 can be fixed to the anti-shake bracket 16. Exemplarily, a portion of the focusing circuit board 23 is fixed to the side plate 162 of the anti-shake bracket 16 and is located at the inner side of the anti-shake bracket 16. A portion of the focusing circuit board 23 is also fixed to the first protrusion 163a and the second protrusion 163b of the anti-shake bracket 16. Among them, a portion of the focusing circuit board 23 is located between the first protrusion 163a and the side plate 162, a portion is located between the first protrusion 163a and the second protrusion 163b, and a portion is located between the second protrusion 163b and the side plate 162.

[0229] Exemplarily, the focusing coil 221 can be fixedly connected to the focusing circuit board 23 and electrically connected to the focusing circuit board 23. In an embodiment, the focusing coil 221 can be fixedly connected to the side of the first fixed portion 231 away from the side plate 162 of the anti-shake bracket 16.

[0230] Exemplarily, the focusing drive mechanism 22 further comprises a focusing sensor 24. The focusing sensor 24 can be fixedly connected to the focusing circuit board 23 and electrically connected to the focusing circuit board 23. In an embodiment, the focusing sensor 24 can be fixedly connected to the side of the first fixed portion 231 away from the side plate 162 of the anti-shake bracket 16 and is located at the inner side of the focusing coil 221.

[0231] FIG. 23 is a partial structural assembly view seven of the motor 1 shown in FIG. 5 in an embodiment.

[0232] As shown in FIG. 23, exemplarily, the focusing bracket 21 can be generally frame-shaped, and the focusing bracket 21 has a mounting space 21a.

[0233] Exemplarily, the focusing bracket 21 comprises a plurality of second mounting grooves 211.

[0234] Exemplarily, the number of the second mounting grooves 211 can be two. The two second mounting grooves 211 can be arranged back to the mounting space 21a and are spaced apart.

[0235] Exemplarily, the focusing magnetic member 222 can be fixedly connected to the focusing bracket 21. Exemplarily, the focusing magnetic member 222 can be fixed to the focusing bracket 21 by adhesion or the like.

[0236] Exemplarily, the focusing magnetic member 222 can be a magnet or a component with magnetism. In the embodiment, the focusing magnetic member 222 comprises two magnets arranged along the third direction Z.

[0237] FIG. 24 is a partial structural assembly view two of the camera module 100 shown in FIG. 4 in an embodiment. FIG. 25 is a partial cross-sectional schematic view of the camera module 100 shown in FIG. 24 in an embodiment at the line E-E.

[0238] As shown in FIG. 24 and FIG. 25, the focusing holder 21 can be slidingly connected to the anti-shake holder 16. Exemplarily, two first mounting slots 165 of the anti-shake holder 16 correspond to two second mounting slots 211 (see FIG. 23) of the focusing holder 21. Among them, two third connecting members 133 are mounted in the first mounting slots 165 of the anti-shake holder 16 and at least partially embedded in the second mounting slots 211 of the focusing holder 21. The relative sliding direction of the anti-shake holder 16 and the focusing holder 21 can be parallel to the third direction Z. In other embodiments, the third connecting members 133 can be fixedly connected to the second mounting slots 211 of the focusing holder 21 and at least partially embedded in the first mounting slots 165 of the anti-shake holder 16.

[0239] Exemplarily, a buffer (not shown in the drawings) is arranged between the anti-shake holder 16 and the focusing holder 21, which can reduce the collision between the anti-shake holder 16 and the focusing holder 21, thereby avoiding damage to the anti-shake holder 16 and the focusing holder 21.

[0240] As shown in FIG. 25, exemplarily, the focusing coil 221 can be arranged corresponding to the focusing magnetic member 222.

[0241] Exemplarily, the second lens 3 can be fixedly connected to the focusing holder 21. The mounting space 21a of the focusing holder 21 can be used to mount the second lens 3. At least part of the second lens 3 can be located outside the focusing holder 21.

[0242] Exemplarily, the mounting space 21a of the focusing holder 21 can be arranged opposite to the mounting hole 16a of the anti-shake holder 16. In this way, the optical axis of the first lens 2 can be substantially parallel to the optical axis of the second lens 3.

[0243] As shown in FIG. 25, the focusing coil 221 is fixed to the focusing circuit board 23, the focusing magnetic member 222 is fixed to the focusing holder 21, and the focusing coil 221 faces the focusing magnetic member 222 for driving the focusing holder 21 to move along the third direction Z relative to the anti-shake holder 16. When the focusing holder 21 moves along the third direction Z relative to the anti-shake holder 16, the focusing holder 21 can drive the second lens 3 mounted thereon to move along the third direction Z, at this time, the motor 1 can realize the auto-focusing of the camera module 100. It can be understood that the focusing coil 221 facing the focusing magnetic member 222 means that the winding plane of the focusing coil 221 faces the focusing magnetic member 222.

[0244] Exemplarily, the focusing sensor 24 can be used to detect the position change of the focusing holder 21 in the third direction Z. In this way, the camera module 100 can adjust the position of the focusing holder 21 according to the detection result of the focusing sensor 24, so as to achieve better focusing effect.

[0245] It can be understood that the focusing driving mechanism 22 drives the focusing support 21 to move along the third direction Z, thereby driving the second lens 3 to move along the third direction Z, and thus achieving the auto-focusing of the camera module 100. In this case, when the second lens 3 is auto-focused, the relative distance between the first lens 2 and the second lens 3 in the third direction Z will change, and a smaller distance change can achieve a larger focal length change, which is conducive to improving the focusing capability of the camera module 100. It can be understood that the second lens 3 with a shorter focusing stroke can achieve the auto-focusing of the motor 1 in the macro state, thereby improving the imaging quality of the camera module 100 in the macro state.

[0246] FIG. 26 is a partial cross-sectional schematic view of an embodiment of the camera module 100 shown in FIG. 24 at the F-F line.

[0247] As shown in FIGS. 25 and 26, the first anti-shake coil 141 and the first anti-shake magnetic member 142 are correspondingly arranged, and the second anti-shake coil 143 and the second anti-shake magnetic member 144 are correspondingly arranged. The first anti-shake coil 141 and the first anti-shake magnetic member 142, and the second anti-shake coil 143 and the second anti-shake magnetic member 144 jointly drive the anti-shake support 16 to move along the X-Y plane, thereby driving the first lens 2 to move along the X-Y plane, and thus achieving the optical anti-shake of the camera module 100.

[0248] It can be understood that, compared with the split motor 1 in which the anti-shake module 1b and the focusing module 1c are separately arranged, the integrated motor 1 formed by the anti-shake module 1b and the focusing module 1c has a smaller volume, which is conducive to the miniaturization of the camera module 100, thereby saving the internal space of the electronic device 1000. In addition, the integrated motor 1 reduces one motor compared with the split motor, which can reduce the manufacturing cost of the camera module 100.

[0249] It can be understood that, compared with the scheme of achieving the optical anti-shake and the auto-focusing by driving the same lens through the anti-shake module 1b and the focusing module 1c, the scheme of achieving the optical anti-shake and the auto-focusing by driving the first lens 2 through the anti-shake module 1b and driving the second lens 3 through the focusing module 1c can drive only the second lens 3 to move along the third direction Z when the camera module 100 is focused, and the first lens 2 does not need to move along the third direction Z. In this way, the focusing stroke of the camera module 100 is the distance of the movement of the second lens 3 along the optical axis direction thereof, and compared with the camera module 100 with the same imaging quality, the focusing stroke of the camera module 100 of the present embodiment is shorter.

[0250] It can be understood that the group arrangement of the first lens 2 and the second lens 3 of the camera module 100 can avoid the anti-shake image rotation problem of the camera module 100, and the user has a better focusing experience.

[0251] It can be understood that the optical axis directions of the first lens 2 and the second lens 3 can be substantially parallel to the thickness direction of the electronic device 1000, the diameters of the first lens 2 and the second lens 3 are not limited by the thickness of the electronic device 1000, the lenses do not need to be cut to a specific diameter range in the thickness direction of the electronic device 1000, the first lens 2 and the second lens 3 are symmetrical in the second direction Y and the third direction Z, and the camera module 100 has no imaging ST separation and poor resolution.

[0252] FIG. 27 is a partial structure assembly view III of the camera module 100 shown in FIG. 4 in an embodiment.

[0253] As shown in FIG. 27, the pressing piece 17 can be fixed to the side of the anti-shake bracket 16 away from the base 11, for example. It can be understood that the pressing piece 17 can cooperate with the anti-shake bracket 16 to limit the movement stroke of the focusing bracket 21 in the third direction Z, so as to prevent the focusing bracket 21 from being separated from the anti-shake bracket 16 during focusing.

[0254] FIG. 28 is a structure enlarged schematic view of the shell 18 shown in FIG. 5 from another angle.

[0255] As shown in FIG. 28, the shell 18 can be substantially a square cover, for example.

[0256] The shell 18 is provided with a through hole 181, and part of the structure of the motor 1 can be exposed through the through hole 181, for example.

[0257] The shell 18 is provided with a buffer piece 182, which is located inside the shell 18 and on one side of the through hole 181, for example.

[0258] FIG. 29 is a partial cross-sectional schematic view of the camera module 100 shown in FIG. 3 in an embodiment at the G-G line.

[0259] As shown in FIGS. 28 and 29, the shell 18 can be adapted to the shape of the base 11, and the shell 18 can be covered on the base 11, for example. The shell 18 can be fixedly connected with the base 11 by gluing or the like. The shell 18 can be assembled and cooperated with the base 11 to jointly encapsulate and protect the internal structure of the motor 1.

[0260] Part of the structure of the focusing bracket 21 and the second lens 3 can be exposed through the through hole 181 of the shell 18, for example.

[0261] The buffer piece 182 can be spaced apart from the pressing piece 17, for example. It can be understood that the buffer piece 182 can prevent the collision between the pressing piece 17 and the shell 18.

[0262] FIG. 30 is a partial exploded schematic view of the prism assembly 4 shown in FIG. 4 in an embodiment.

[0263] As shown in FIG. 30, the prism assembly 4 comprises a prism 41, a prism holder 42 and a light shield 43.

The first surface 411, the first side surface 413, the second surface 412 and the second side surface 414 can be connected in sequence.

[0268] It can be understood that the light shield 43 separates the first surface 411, thereby forming the incident surface S7 and the exit surface S11 arranged at intervals. That is, the light shield 43 can be located between the incident surface S7 and the exit surface S11 of the prism 41, preventing light from being emitted from the prism 41 in advance from the part between the incident surface S7 and the exit surface S11.

[0269] It can be understood that the incident surface S7 and the exit surface S11 of the prism 41 in the present embodiment are both located on the first surface 411 of the prism 41, that is, the incident surface S7 and the exit surface S11 are located on the same side of the prism assembly 4. In other embodiments, the incident surface S7 and the exit surface S11 of the prism 41 can be located on the first surface 411 of the prism 41 and on any one of the second surface 412, the first side surface 413 and the second side surface 414 of the prism 41, respectively.

[0293] Exemplarily, the light enters the inside of the camera module 100 from the second lens 3, and then enters the inside of the prism 41 in sequence after passing through the first lens 2 and the incident surface S7 of the prism 41. After entering the prism 41, the light can be reflected on a part of the first side surface 413, a part of the first surface 411 and a part of the second side surface 414 of the prism 41 in sequence, and the light after at least three times of reflection can be emitted from the exit surface S11 of the prism 41 and reach the image sensor 51 through the filter 52. The image sensor 51 converts the image information carried by the light into an electrical signal, thereby realizing imaging.

[0294] It can be understood that the light can be folded at least three times in the inside of the prism 41 after entering the prism 41. In this way, the light path of the camera module 100 is long, and the camera module 100 can realize shooting in a long-focus state, thereby improving the imaging quality of the camera module 100 in the long-focus state. In other embodiments, the light can be folded twice in the inside of the prism 41. At this time, the exit surface S11 of the prism 41 can be a part of the second side surface 414 of the prism 41, and the image sensor 51 of the image sensor assembly 5 can be arranged to face the second side surface 414.

[0295] It can be understood that in an embodiment, the first lens 2 and the second lens 3 are driven to move on the X-Y plane by the anti-shake module 1b to realize optical anti-shake, the second lens 3 is driven to move along the third direction Z by the focusing module 1c to realize automatic focusing, and the anti-shake module 1b and the focusing module 1c are integrated into one structure. The motor 1 has a simple structure, a small size and a low manufacturing cost.

[0296] It can be understood that when the camera module 100 switches to shooting in the long-focus state, the focusing module 1c can drive the second lens 3 to move in the third direction Z to the image side of the camera module 100, change the focal length of the camera module 100, and enable the camera module 100 to focus and shoot in the long-focus state. In addition, by setting the motor 1 to be fixedly connected with the prism assembly 4, and the incident surface S7 of the prism 41 to face the first lens 2 and the second lens 3, and by setting the image sensor assembly 5 to be fixedly connected with the prism assembly 4, and the emergent surface S11 of the prism 41 to face the image sensor 51, the reflection path of light in the prism 41 is long, the long-focus characteristic of the camera module 100 is met, and the long-focus shooting performance of the camera module 100 is improved.

[0297] It can be understood that when the camera module 100 switches to shooting in the macro state, the focusing module 1c can drive the second lens 3 to move in the third direction Z to the object side of the camera module 100, change the focal length of the camera module 100, and enable the camera module 100 to focus and shoot in the macro state.

[0298] It can be understood that when the camera module 100 is working, the first lens 2 remains stationary in the third direction Z, and the second lens 3 moves in the third direction Z to achieve focusing. The structure of the camera module 100 is reasonably arranged, so that the movement distance of the second lens 3 in the third direction Z is the focusing stroke of the camera module 100. Since the movement distance of the second lens 3 is small, the focusing stroke of the camera module 100 is also small, and the space requirement of the camera module 100 in the third direction Z is also small, which enables the miniaturization of the camera module 100 and the thinness of the electronic device 1000.

[0299] The structures of the related components of the camera module 100 are specifically introduced above. The structure of the camera module 100 and the setting of the related optical parameters will be specifically introduced below with reference to the drawings.

[0300] Exemplarily, the first lens 2 and the second lens 3 can have opposite optical powers. Exemplarily, the first lens 2 can have a positive optical power, and the second lens 3 can have a negative optical power, or the first lens 2 can have a negative optical power, and the second lens 3 can have a positive optical power. It can be understood that by reasonably configuring the optical powers of the first lens 2 and the second lens 3, and setting the first lens 2 and the second lens 3 to have opposite optical powers, the focusing and macro focusing can be achieved, the focusing stroke can be reduced, the focusing ability can be improved, the overall image quality of the camera module 100 when imaging a close-range scene can be improved, the light amount of the system can be increased, the macro imaging can be promoted, and the difference in imaging quality between long-range shooting and close-range shooting can be balanced. When shooting objects at different distances, the image quality is good, and the imaging clarity is high.

[0301] It can be understood that when the first lens 2 has a negative focal length and the second lens 3 has a positive focal length, the second lens 3 can be used for light beam convergence, so that the diameter of the light beam entering the first lens 2 is smaller, the aperture of the first lens 2 is no longer the maximum limit of the light aperture, which is beneficial to the miniaturization and large aperture design of the camera module 100, effectively increases the light aperture, realizes a smaller aperture number, and can enhance the focusing ability, which is beneficial to realize macro shooting.

[0302] In an embodiment, the first lens 2 can include at least one lens, the second lens 3 can include at least one lens, and the first lens 2 can include at least one lens with a negative focal length. Illustratively, the second lens 3 includes a first lens L1 and a second lens L2, the first lens 2 includes a third lens L3, the first lens L1, the second lens L2 and the third lens L3 can be arranged in order from the object side to the image side, the first lens L1 can have a positive focal length, the second lens L2 can have a negative focal length, and the third lens L3 can have a negative focal length. It can be understood that reasonable configuration of the focal lengths of the first lens L1, the second lens L2 and the third lens L3 is beneficial to realize the miniaturization, large aperture and long focal length of the camera module 100, and is beneficial to the realization of the focusing process of the camera module 100 from the distance to the close range and the improvement of the imaging quality of the camera module 100.

[0303] Illustratively, the second lens 3 can include at least one lens with an Abbe number less than 40. For example, the Abbe number of the lens of the second lens 3 can be equal to 5, 10, 22, 38 or 39, etc. It can be understood that the second lens 3 can include at least one lens with high dispersion, and by limiting the Abbe number of at least one lens in the second lens 3 to be less than 40, it is beneficial to reduce the chromatic aberration in the camera module 100, so that the camera module 100 has good imaging quality.

[0304] Illustratively, the second lens 3 can include a lens with a positive focal length, and the material of the lens with the smallest focal length is glass. By setting the lens with the smallest focal length and a positive focal length in the second lens 3 to be glass material, it is beneficial to reduce the size of the camera module 100, realize the miniaturization of the camera module 100, and reduce the temperature drift coefficient, reduce the temperature drift effect, and improve the imaging quality of the camera module 100.

[0305] Illustratively, the Abbe number of the lens in the first lens 2 is different from the Abbe number of the prism 41 of the prism assembly 4, which is beneficial to correct the chromatic aberration from infinity to micro distance, thereby improving the imaging quality of the camera module 100.

[0306] Exemplarily, the camera module 100 can satisfy: f1 / EFL>-1, where f1 is the focal length of the first lens 2, and EFL is the effective focal length of the camera module 100. For example, the value of f1 / EFL can be equal to -0.999, -0.88, -0.7, 0.56, -0.3, or -0.1, etc. In other embodiments, the value of f1 / EFL can also satisfy other ranges. It can be understood that by reasonably limiting the range of f1 / EFL, it is beneficial to reduce the aperture number, realize the design of large aperture, improve the light aperture of the camera module 100, and ensure the good imaging quality of the camera module 100.

[0307] Exemplarily, the camera module 100 can satisfy: f2 / EFL≤0.9, where f2 is the focal length of the second lens 3. For example, the value of f2 / EFL can be equal to 0.001, 0.11, 0.23, 0.38, 0.45, 0.5, 0.66, 0.75, 0.88, or 0.9, etc. In other embodiments, the value of f2 / EFL can also satisfy other ranges. It can be understood that by limiting the range of f2 / EFL, the camera module 100 can balance the image quality difference between long-range shooting and close-range shooting of the camera module 100 under smaller assembly sensitivity, and obtain more uniform image quality.

[0308] It can be understood that by reasonably limiting the ranges of f1 / EFL and f2 / EFL, the optical powers of the first lens 2 and the second lens 3 can be reasonably configured, which is beneficial to shorten the focusing stroke of the camera module 100, improve the focusing ability of the camera module 100, realize the shooting of the camera module 100 in the macro state, and have good image quality when shooting objects at different distances.

[0309] Exemplarily, the second lens 3 includes at least one lens with positive optical power, and the ratio of the focal length of the at least one lens with positive optical power in the second lens 3 to the effective focal length EFL of the camera module 100 is less than 1. It can be understood that by setting the ratio of the focal length of the at least one lens with positive optical power in the second lens 3 to the effective focal length EFL of the camera module 100 to be less than 1, it can be ensured that the second lens 3 with a smaller number of lenses can provide sufficient optical power for the camera module 100, and the size of the second lens 3 can be reduced, which is beneficial to realize macro shooting and long-focus and miniaturization design of the camera module 100.

[0310] Exemplarily, the camera module 100 can satisfy: FOV<50°, where FOV is the field of view of the camera module 100. For example, the value of FOV can be equal to 49.9, 30, 23, 18, 10, 8, 5.3, 3.8, or 0.6, etc. It can be understood that by setting the field of view of the camera module 100, the camera module 100 has long-focus characteristics.

[0311] Exemplarily, the camera module 100 can satisfy: IH>2mm, wherein IH is the maximum image height of the camera module 100. For example, the value of IH can be equal to 2.01, 2.38, 3.54, 4.36, 6.66 or 8.88, etc. It can be understood that by reasonably limiting the range of IH, the camera module 100 has the characteristics of a large target surface, and is conducive to achieving a higher imaging magnification and improving the resolving power of the camera module 100.

[0312] Exemplarily, the camera module 100 can satisfy: L / IH>2, wherein L is the total optical path length of the light in the prism 41 of the prism assembly 4. For example, the value of L / IH can be equal to 2.1, 3.8, 4.5, 5.87, 6.66 or 8.88, etc. It can be understood that the total optical path length L of the light in the prism 41 is greater than twice the image height IH, which is conducive to folding and increasing the optical path of the light, and is conducive to achieving the long-focus characteristics and miniaturization of the camera module 100.

[0313] Exemplarily, the camera module 100 can satisfy: Fno<3.6, wherein Fno is the aperture number of the camera module 100. For example, the value of Fno can be equal to 0.5, 0.99, 1.53, 1.66, 2.38, 2.66, 3.02 or 3.59, etc. It can be understood that the smaller the value of Fno of the camera module 100, the larger the aperture of the camera module 100; the larger the value of Fno of the camera module 100, the smaller the aperture of the camera module 100. By limiting the value of Fno of the camera module 100, the camera module 100 has the characteristics of a large aperture.
