Description

Technical Field

[0001] This disclosure relates to the field of camera module technology, and more particularly to a periscope camera module and electronic device. Background Technology

[0002] With the development of mobile smart terminal technology, terminal devices are increasingly demanding higher imaging quality for long-distance shooting scenarios. Periscope camera modules, by reversing the optical path and adjusting it to be parallel to the camera body plane, can extend the total optical length without increasing the thickness of the camera body, and are widely used in telephoto shooting on smart terminals.

[0003] Currently, most periscope camera modules adopt an integrated structure, with all internal components integrated into the module cavity, which is embedded in the smart terminal body. The total optical length and the horizontal space occupied by the module are fixed values.

[0004] However, higher optical zoom ratios and larger image sensors require longer overall optical lengths. The overall optical length of the integrated periscope camera module is limited by the fixed horizontal space of the smart terminal body, making it difficult to flexibly adjust and extend, and thus difficult to adapt to the ever-increasing demand for telephoto imaging.

[0022] As mentioned earlier, with the development of mobile smart terminal technology, the imaging quality requirements of terminal devices for long-distance shooting scenarios are constantly increasing. Periscope camera modules, by reversing the optical path and adjusting it to be parallel to the body plane, can extend the total optical length without increasing the thickness of the body, and are widely used in telephoto shooting of smart terminals. Currently, most existing periscope camera modules adopt an integrated structure, with all internal components integrated into the module cavity, which is embedded in the smart terminal body. Its total optical length and the lateral space occupied by the module are fixed values. However, higher optical zoom ratios and larger image sensors require longer total optical lengths. The total optical length of the integrated periscope camera module is limited by the fixed lateral space of the smart terminal body, and cannot be flexibly adjusted and extended, making it difficult to adapt to the ever-increasing demand for telephoto imaging.

[0023] This disclosure provides a periscope camera module and an electronic device. The periscope camera module includes: a housing, a base, a driving component, an imaging component, and an image sensor; both the housing and the base are cylindrical structures with one open end, and the inner cross-sectional dimension of the housing is larger than the outer cross-sectional dimension of the base; the base is used to connect with the electronic device, and the base is at least partially fitted inside the housing, with the open end of the base located inside the housing; the imaging component is at least partially disposed inside the housing and connected to the inner side of the closed end of the housing, and the image sensor is disposed at the closed end of the base, with the optical axis of the image sensor coaxial with the output optical axis of the imaging component; the output end of the driving component is connected to the housing for transmission, and the driving component is used to drive the housing to move relative to the base in a direction parallel to the output optical axis. Through the split-nested housing and base structure, combined with the driving component that can drive the housing to reciprocate along the output optical axis, a periscope camera module structure with variable axial optical length is provided. This periscope camera module extends the imaging component through the outer shell, which can physically lengthen the total axial length of the imaging optical path and linearly increase the axial distance between the imaging component and the image sensor. This provides a physical space basis for the adaptation of large-size photosensitive image sensors and long-focal-length optical imaging systems, thereby improving the quality of long-focal-length imaging.

[0024] The periscope camera module 100 and electronic device 200 provided in this disclosure are described below through embodiments.

[0025] Figure 1 This is a schematic diagram of the structure of a periscope camera module 100 provided in an embodiment of this disclosure. Figure 2 This is an exploded view of a periscope camera module 100 disclosed herein. Figures 1 to 2As shown, the periscope camera module 100 includes a housing 1, a base 2, a drive assembly (not shown), an imaging assembly 3, and an image sensor 4. Both the housing 1 and the base 2 are cylindrical structures with one open end, and the cross-sectional dimension of the inner cavity of the housing 1 is larger than the outer cross-sectional dimension of the base 2. The base 2 is used to connect to the electronic device 200. The base 2 is at least partially fitted inside the housing 1, with the open end of the base 2 located inside the housing 1; the imaging assembly 3 is at least partially disposed inside the housing 1 and connected to the inner side of the closed end of the housing 1. The image sensor 4 is disposed at the closed end of the base 2, and the optical axis of the image sensor 4 is coaxial with the output optical axis of the imaging assembly 3. The output end of the drive assembly is connected to the housing 1 via a transmission, and the drive assembly is used to drive the housing 1 to move relative to the base 2 in a direction parallel to the output optical axis.

[0026] Both the outer casing 1 and the base 2 are single-ended cylindrical structures, open at one end and closed at the other. The central axes of both the outer casing 1 and the base 2 are parallel to the output optical axis of the imaging component 3. Preferably, the central axes of both the outer casing 1 and the base 2 are coaxial with the output optical axis of the imaging component 3. For example, the cross-section of the cylindrical structures of the outer casing 1 and the base 2 can be square, and the overall structure can adopt a cuboid-shaped cylindrical configuration to fit the internal installation space of the electronic device 200. Within the cross-section perpendicular to the output optical axis, the inner cavity cross-sectional dimension of the outer casing 1 is larger than the outer contour cross-sectional dimension of the base 2, providing a structural space basis for the nested sliding fit between the outer casing 1 and the base 2.

[0027] The base 2 can be fixedly connected to the body of the electronic device 200 to achieve the positioning and installation of the camera module inside the electronic device 200. The electronic device 200 includes, but is not limited to, smartphones, tablets, and portable shooting devices. The open end of the base 2 is positioned facing the closed end of the housing 1, and the base 2 is at least partially fitted into the inner cavity of the housing 1. The open end of the base 2 is entirely located within the inner cavity of the housing 1, thereby forming a nested mating structure in which the housing 1 can slide relative to the base 2 along the direction of the emitted optical axis.

[0028] In one example, such as Figure 2As shown, the base 2 adopts a split-type assembly structure, including a first base sub-shell 21 and a second base sub-shell 22. The first base sub-shell 21 and the second base sub-shell 22 are mutually matching semi-cylindrical configurations, and their axial extension directions are both parallel to the output optical axis of the imaging component 3. The splicing surfaces of the first base sub-shell 21 and the second base sub-shell 22 are parallel to the output optical axis, and they can be fixed together by adhesive, snap-fit ​​connection, laser welding, or threaded fastening, forming a complete sealed cylindrical inner cavity after splicing. The assembled base 2 is a single-end cylindrical structure with one open end and the other closed end. The first base sub-shell 21 has an integral closed end face at one axial end, which constitutes the closed end of the base 2 and is used for positioning and mounting the image sensor 4. The other axial ends of the first base sub-shell 21 and the second base sub-shell 22 together form the open end of the base 2, which faces the closed end of the outer shell 1. The outer cross-sectional dimension of the assembled base 2 is smaller than the inner cross-sectional dimension of the outer shell 1. The base 2 is at least partially fitted into the inner cavity of the outer shell 1, and the open end of the base 2 is entirely located within the inner cavity of the outer shell 1, thereby forming a nested fit structure in which the outer shell 1 can slide freely relative to the base 2 along the axial direction.

[0029] Imaging component 3 is at least partially housed within the inner cavity of housing 1, and is connected to the inner surface of the closed end of housing 1, allowing imaging component 3 to move synchronously with housing 1 along the outgoing optical axis. Image sensor 4 is mounted on the closed end of base 2, with its photosensitive surface facing the open end of base 2. The optical axis of image sensor 4 is coaxial with the outgoing optical axis of imaging component 3, so that the imaging light emitted from imaging component 3 is incident along the optical axis onto the photosensitive surface of image sensor 4, completing photoelectric signal conversion and image acquisition.

[0030] Image sensor 4 can be directly mounted inside the closed end of base 2. Alternatively, image sensor 4 can be mounted on the outer surface of the closed end of base 2, which is the side of the closed end of base 2 facing away from its open end. A light-transmitting hole is formed at the closed end of base 2 corresponding to the photosensitive area of ​​image sensor 4. The central axis of the light-transmitting hole is coaxial with the output optical axis of imaging assembly 3 and the optical axis of image sensor 4. The effective aperture of the light-transmitting hole is not less than the maximum size of the photosensitive surface of image sensor 4, to completely cover the photosensitive surface area. Imaging light emitted from imaging assembly 3 can pass through the light-transmitting hole and enter the photosensitive surface of image sensor 4 without obstruction, completing photoelectric signal conversion and image acquisition.

[0031] The fixed end of the drive component can be connected to the body or base 2 of the electronic device 200, and the output end of the drive component is connected to the housing 1 via a transmission connection. The drive component can output a linear reciprocating drive force along the direction of the emitted optical axis to drive the housing 1 to reciprocate linearly relative to the base 2 in a direction parallel to the emitted optical axis. For example, the drive component can be a voice coil motor, a stepper screw mechanism, or a piezoelectric drive device, etc. When the housing 1 moves towards the closed end of the base 2, the nesting overlap length between the housing 1 and the base 2 increases, and the overall axial length of the module shortens, entering a retracted state in the non-shooting state. When the housing 1 moves away from the closed end of the base 2, the nesting overlap length between the housing 1 and the base 2 decreases, and the overall axial length of the module increases, entering an extended state in the shooting state.

[0032] In this embodiment, a periscope camera module 100 with variable axial optical length is provided by means of a split nested shell 1 and base 2 structure, in conjunction with a drive component that can drive the shell 1 to reciprocate along the direction of the outgoing optical axis. This periscope camera module 100, by extending the imaging component 3 through the shell 1, can physically lengthen the axial length of the imaging optical path, linearly increasing the axial distance between the imaging component 3 and the image sensor 4. This provides a physical space basis for the adaptation and application of large-size photosensitive image sensors and long-focal-length optical imaging systems, thereby improving the quality of long-focal-length imaging.

[0033] In one possible implementation, such as Figure 2 As shown, the periscope camera module 100 also includes a first guide rail 5. The first guide rail 5 is disposed on the inner side wall of the housing 1, and the extending direction of the first guide rail 5 is parallel to the emitted optical axis. The first guide rail 5 is used to cooperate with the first guide rail mating part disposed on the electronic device 200, so that the housing 1 moves relative to the base 2 in a direction parallel to the emitted optical axis under the drive of the drive component.

[0034] The first guide rail 5 and the first guide rail mating part can form a sliding guide fit to limit the movement direction of the housing 1 relative to the base 2. The first guide rail 5 is disposed on the inner side wall of the housing 1, and the extension direction of the first guide rail 5 is parallel to the output optical axis of the imaging component 3. The first guide rail mating part is disposed in the corresponding area of ​​the electronic device 200 corresponding to the placement position of the first guide rail 5, and the first guide rail mating part is a sliding fit structure adapted to the first guide rail 5. The first guide rail 5 can be in the form of a raised rail body, a grooved rail body, a sliding column guide rail, etc., and correspondingly, the first guide rail mating part can be in the form of a groove structure, a raised structure, or a guide hole structure, etc.

[0035] The first guide rail 5 extends at least partially beyond the open end of the housing 1, reaching the outside of the housing 1 and engaging with the first guide rail mating part on the electronic device 200, so that the housing 1 moves relative to the base 2 in a direction parallel to the emitted optical axis under the drive of the drive assembly. The extension length of the first guide rail 5 can be adapted to the maximum extension stroke of the housing 1 to ensure that the first guide rail 5 and the first guide rail mating part maintain a stable engagement relationship in both the retracted and extended states of the housing 1. At least one set of first guide rails 5 can be arranged circumferentially along the inner sidewall of the housing 1, with corresponding first guide rail mating parts arranged one-to-one with the first guide rail 5, to radially limit and guide the linear reciprocating motion of the housing 1 relative to the base 2.

[0036] In this embodiment of the present disclosure, the guiding and cooperating structure formed by the first guide rail 5 and the first guide rail mating part can accurately limit and guide the reciprocating motion of the outer shell 1 along the direction of the outgoing optical axis, constrain the radial offset and attitude deflection of the outer shell 1 during the movement, ensure the coaxiality and motion stability of the optical axis during the extension and retraction of the outer shell 1, and thus ensure the quality of telephoto imaging.

[0037] In one possible implementation, the imaging component 3 includes a prism 31 and an imaging lens 32. Both the prism 31 and the imaging lens 32 are disposed inside the housing 1. The prism 31 is used to refract the incident light to the outgoing optical axis, and the imaging lens 32 is used to focus the refracted incident light onto the photosensitive surface of the image sensor 4.

[0038] Both the prism 31 and the imaging lens 32 are housed within the inner cavity of the housing 1. A light-entry aperture is provided on the side wall of the housing 1. The effective aperture diameter of the light-entry aperture is not less than the maximum outline size of the light-entry surface of the prism 31, and the light-entry surface of the prism 31 faces the light-entry aperture. When the periscope camera module 100 is in shooting mode, the driving component can drive the housing 1 to extend, exposing the light-entry aperture outside the electronic device body 201, so that ambient light can enter the light-entry surface of the prism 31 without obstruction through the light-entry aperture. The light-exiting surface of the prism 31 faces the light-entry side of the imaging lens 32. The prism 31 is used to refract the ambient light incident perpendicular to the outgoing optical axis, so that the refracted light enters the imaging lens 32 along the outgoing optical axis.

[0039] An imaging lens 32 is arranged between the prism 31 and the image sensor 4 along the outgoing optical axis. The imaging lens 32 receives the incident light rays refracted by the prism 31 and focuses these rays onto the photosensitive surface area of ​​the image sensor 4. The prism 31 can be an optical prism configuration capable of 90° optical path refracting. The imaging lens 32 can be a fixed-focus lens group or a zoom lens group, with the optical axis of the lens group coaxial with the outgoing optical axis of the imaging assembly 3 and the optical axis of the image sensor 4 to ensure coaxiality of the optical path transmission.

[0040] In this embodiment, by configuring a combined optical structure of a prism 31 and an imaging lens 32 inside the telescopic housing 1, external incident light can be deflected along the periscope optical path to the outgoing optical axis aligned with the telescopic direction of the module. The deflected light is then focused and converged onto the photosensitive surface of the image sensor 4 by the imaging lens 32. This design can accommodate axially telescopic camera module structures, achieving a compact periscope optical path, and ensures stable transmission and precise focusing of imaging light when the housing 1 telescopically changes the length of the optical path. This provides a stable optical foundation for imaging schemes using a large-size image sensor 4 with a high-magnification telephoto lens.

[0041] In one possible implementation, such as Figure 2 As shown, the periscope camera module 100 also includes a connecting spring 6, an inner shell 7, and a lens actuator. The inner shell 7 has a cylindrical structure, and the outer cross-sectional dimension of the inner shell 7 is smaller than the inner cavity cross-sectional dimension of the base 2. The first end of the inner shell 7 is at least partially fitted inside the outer shell 1, and the second end of the inner shell 7 is at least partially fitted inside the base 2. The lens actuator, prism 31, and imaging lens 32 are all disposed inside the inner shell 7. One end of the connecting spring 6 is connected to the outer shell 1, and the other end of the connecting spring 6 is connected to the inner shell 7. A second guide rail (not shown in the figure) is provided on the outer side wall of the inner shell 7, and a second guide rail mating part (not shown in the figure) is provided inside the base 2 to cooperate with the second guide rail. The extension direction of the second guide rail is parallel to the output optical axis.

[0042] The inner shell 7 has a cylindrical structure, and its outer cross-sectional dimension is smaller than that of the inner cavity of the base 2, providing a suitable space for the inner shell 7 to move relative to the base 2 along the axial direction of the emitted optical axis. The inner shell 7 is disposed within the nested cavity formed by the outer shell 1 and the base 2, with at least a partial first end of the inner shell 7 fitted inside the outer shell 1 and at least a partial second end fitted inside the base 2. The lens actuator, prism 31, and imaging lens 32 are all disposed within the internal cavity of the inner shell 7. The lens actuator is used to drive the movement of the prism 31 and the imaging lens 32 to achieve focusing and / or optical image stabilization adjustment.

[0043] Figure 3 This is a schematic diagram of the exploded structure of an inner shell 7 provided in this disclosure. Figure 4 This is a schematic diagram of the exploded structure of another inner shell 7 provided in this disclosure. Figure 5 This is another exploded structural diagram of the inner shell 7 provided in this disclosure. For example... Figures 3 to 5As shown, the inner shell 7 adopts a split-assembly structure, including a first inner shell sub-shell 71 and a second inner shell sub-shell 72. The first inner shell sub-shell 71 and the second inner shell sub-shell 72 are mutually matching semi-cylindrical configurations, and their axial extension directions are both parallel to the output optical axis of the imaging component 3. The splicing surface of the first inner shell sub-shell 71 and the second inner shell sub-shell 72 is parallel to the output optical axis, and the two can be fixed together by adhesive, snap-fit ​​connection, laser welding or threaded fastening, and together they enclose a complete sealed cylindrical inner cavity. After splicing, the inner shell 7 is a cylindrical structure to accommodate the lens actuator, prism 31 and imaging lens 32.

[0044] One end of the connecting spring 6 is connected to the outer shell 1, and the other end is connected to the inner shell 7. When the outer shell 1 moves along the output optical axis, the inner shell 7 is linked with the outer shell 1 through the connecting spring 6, and moves synchronously with the outer shell 1 along the output optical axis. The connecting spring 6 has elastic deformation capability, and can adapt to the slight radial and circumferential offsets relative to the output optical axis during the movement between the outer shell 1 and the inner shell 7 through its own slight elastic deformation. This flexibly eliminates the constraint redundancy generated during the transmission process and reduces the adverse effects of over-positioning on the smoothness of the module's telescopic movement. Furthermore, the connecting spring 6 can form a preset elastic preload after assembly, providing continuous adaptation preload for the connection interface between the outer shell 1 and the inner shell 7. This preload can compensate for the guide rail fit clearance, reduce the radial movement and axial loosening of the inner shell 7 during axial movement along the output optical axis, and maintain the attitude stability of the optical components inside the inner shell 7.

[0045] The outer wall of the inner shell 7 is provided with a second guide rail (not shown in the figure), the extension direction of which is parallel to the output optical axis of the imaging component 3. The inner wall of the base 2 is provided with a second guide rail mating part (not shown in the figure) corresponding to the arrangement position of the second guide rail. The second guide rail and the second guide rail mating part form a sliding fit structure, which can accurately guide and radially limit the linear movement of the inner shell 7 relative to the base 2, ensuring that the optical axis of the internal optical element and the optical axis of the image sensor 4 remain coaxial during the movement of the inner shell 7.

[0046] In this embodiment, the lens actuator, prism 31, and imaging lens 32 are integrated through the inner shell 7, which reduces accumulated assembly tolerances, ensures the consistency of the relative positions of each optical element, and effectively protects the components inside the inner shell 7, reducing the impact of external vibrations and dust, avoiding mechanical damage during assembly, ensuring the operational stability of the components, and extending their service life. The flexible linkage between the outer shell 1 and the inner shell 7 is achieved through the connecting spring 6, ensuring the synchronization of the extension and retraction movements of the inner shell 7 and the outer shell 1 along the output optical axis, and effectively isolating vibration interference generated by the movement of the outer shell 1, thus improving the smoothness of the module's extension and retraction movement and imaging stability. A sliding fit pair is provided between the inner shell 7 and the base 2 along the output optical axis, providing precise guidance and full-stroke radial limit for the axial movement of the inner shell 7, ensuring the coaxial accuracy of the optical axis of the internal optical elements and the output optical axis. This improves the focusing accuracy and optical image stabilization performance of the module during the full-stroke extension and retraction process, while also enhancing the structural reliability and imaging stability of the module under complex working conditions.

[0047] In one possible implementation, the periscope camera module 100 also includes a circuit board 9. One end of the circuit board 9 is connected to the inner housing 7, and the other end of the circuit board 9 is connected to the base 2. The circuit board 9 includes a bendable structure.

[0048] The first end of circuit board 9 is fixedly mounted to the inner shell 7, and the lines at this end form a stable electrical connection with the lens actuator, drive coil, and other electrical components built into the inner shell 7. This connection is used to transmit power supply and drive control signals to the components built into the inner shell 7, while simultaneously receiving feedback signals from the optical components. The second end of circuit board 9 is fixedly mounted to the base 2, and the lines at this end can electrically interface with the main control circuit of the electronic device 200 or the image sensor 4 circuit on the side of the base 2, completing the signal interaction and power supply circuit setup. In one example, circuit board 9 is a flexible printed circuit board (FPCB).

[0049] The circuit board 9 is equipped with a bendable structure, which can be located in the middle section of the circuit board 9. The bendable structure can be one or a combination of U-shaped bends, S-shaped redundant bends, and wavy deformation sections. The extension length of the bend is adapted to the maximum extension stroke of the inner shell 7 relative to the base 2, so as to ensure that the bendable structure has sufficient deformation margin throughout the entire stroke range of the inner shell 7 in both contracted and extended states. The bendable structure is housed in the nested fit gap between the inner shell 7 and the base 2, and its bending deformation direction is adapted to the extension and contraction direction of the inner shell 7. When the inner shell 7 reciprocates linearly along the output optical axis with the outer shell 1, the axial relative displacement between the inner shell 7 and the base 2 is compensated in real time through the elastic bending deformation of its own bendable structure.

[0050] In this embodiment, the circuit board 9 is connected to the inner shell 7 and the base 2. The middle section of the circuit board 9 includes a bendable structure, which enables stable electrical conduction between the internal electrical components of the inner shell 7 and the circuitry on the side of the base 2, facilitating the interaction of power supply, drive control signal transmission, and optical component feedback signals. Furthermore, the elastic bending deformation of the bendable structure in the middle of the circuit board 9 can compensate for the axial relative displacement between the inner shell 7 and the base 2 in real time, ensuring stable circuit transmission during the relative telescopic movement of the inner shell 7 and the base 2, and guaranteeing the continuity and reliability of the electrical connection during the reciprocating linear telescopic movement of the periscope camera module 100.

[0051] In one possible implementation, such as Figures 3 to 5 As shown, the inner housing 7 includes a first sub-housing 711 and a second sub-housing 712. The lens actuator includes a focusing drive assembly and an image stabilization drive assembly. The image stabilization drive assembly is disposed in the first sub-housing 711, and the focusing drive assembly is disposed in the second sub-housing 712. The image stabilization drive assembly is used to drive the prism 31 to rotate around the X-axis and / or Y-axis, and the focusing drive assembly is used to drive the imaging lens to move along the Z-axis. The Z-axis is parallel to the output optical axis, and the X-axis, Y-axis, and Z-axis are perpendicular to each other.

[0052] The inner shell 7 includes a first sub-shell 711 and a second sub-shell 712. The cavities of the first sub-shell 711 and the second sub-shell 712 are interconnected to allow the imaging optical path to be transmitted unobstructed along the outgoing optical axis. For example, the inner shell 7 may be an integrally formed cylindrical component, with a partition (such as a light-transmitting opening) integrally provided in its inner cavity. Figure 3 (As shown). The internal cavity of the inner shell 7 is directly divided by a partition to form an independent first sub-shell 711 and a second sub-shell 712. The two sub-shells share the outer side wall and main structure of the inner shell 7, and the light path is transmitted along the output optical axis through the light-transmitting openings on the partition. In other embodiments, the inner shell 7 can also adopt an embedded module assembly form, with the module pre-set with an integral inner shell 7 main body. The first sub-shell 711 and the second sub-shell 712 are independent functional carrying modules. After the corresponding components are pre-assembled, they are then assembled into the inner cavity of the inner shell 7 main body in sequence or simultaneously. The inner shell 7 can also adopt a split independent assembly form, with the first sub-shell 711 and the second sub-shell 712 being separately formed split cylindrical components. The two are combined to form a complete inner shell 7 by positioning buckles, adhesive fixing, thread fastening, or nesting.

[0053] The image stabilization drive assembly is mounted in a separate cavity of the first sub-housing 711, and the focus drive assembly is mounted in a separate cavity of the second sub-housing 712. The focus drive assembly and the image stabilization drive assembly are physically separated into separate cavities to avoid mechanical interference between moving parts and to reduce electromagnetic crosstalk between different drive units.

[0054] The image stabilization drive assembly is used to drive the prism 31 to rotate around the X-axis and / or Y-axis, wherein the X-axis, Y-axis and Z-axis are mutually perpendicular, and the X-axis and Y-axis are both perpendicular to the output optical axis, corresponding to the horizontal and vertical compensation directions of the image, respectively. By changing the deflection attitude of the prism 31, the optical path folding angle is adjusted to achieve optical image stabilization compensation.

[0055] The focusing drive assembly is used to drive the imaging lens 32 to reciprocate linearly along the Z-axis, wherein the Z-axis is set parallel to the output optical axis of the imaging assembly 3, and the focusing adjustment is achieved by changing the axial position of the imaging lens 32.

[0056] In this embodiment, the focusing drive assembly and the image stabilization drive assembly are independently arranged in separate cavities through the inner shell 7 structure of the divided cavity, realizing a modular isolation design for the focusing and image stabilization functions. This effectively avoids mechanical interference between the moving parts of the two drive units and reduces electromagnetic crosstalk between the drive coils, improving the control accuracy and response speed of focusing and image stabilization adjustment, thereby improving focusing accuracy and imaging stability in telephoto shooting scenarios. Furthermore, the pre-assembled modular design reduces the overall assembly tolerance of the module, improves the assembly consistency of optical components and drive components, and facilitates individual functional debugging and subsequent maintenance.

[0057] In one possible implementation, such as Figure 3 As shown. The image stabilization drive assembly includes a prism carrier 10, a mounting base 11, a first drive magnet 12, and a first drive coil 13 disposed on the circuit board 9. The mounting base 11 is disposed within the first sub-housing 711, the prism carrier 10 is disposed within the mounting base 11, and the prism 31 is connected to the prism carrier 10. The first drive magnet 12 is connected to the prism carrier 10 and is used to cooperate with the first drive coil 13 to drive the prism carrier 10 to rotate relative to the mounting base 11, and / or the first drive magnet 12 is connected to the mounting base 11 and is used to cooperate with the first drive coil 13 to drive the mounting base 11 to rotate relative to the first sub-housing 711.

[0058] Mounting base 11, serving as the primary load-bearing structure of the anti-shake drive assembly, is rotatably mounted within the inner cavity of the first sub-housing 711. Prism carrier 10, serving as the secondary load-bearing structure, is also rotatably mounted within the inner cavity of mounting base 11. Prism 31 is fixedly embedded in a pre-set mounting position within prism carrier 10, maintaining a fixed relative position. Prism 31, prism carrier 10, and mounting base 11 form a hierarchical movable load-bearing structure, providing freedom of movement for multi-dimensional angular rotation adjustment of prism 31.

[0059] The first driving magnet 12 can be fixedly connected to the prism carrier 10 and / or to the mounting base 11. The first driving coil 13 is fixed to the corresponding inner wall position of the circuit board 9, and the working surfaces of the first driving coil 13 and the first driving magnet 12 are arranged opposite to each other to form an electromagnetic driving pair. The circuit of the first driving coil 13 is electrically connected to the circuit board 9 and can receive a preset driving control current. After being energized, the first driving coil 13 can generate a driving magnetic field that interacts with the permanent magnet magnetic field of the first driving magnet 12. By controlling the magnitude, direction and timing of the current, the magnitude and direction of the electromagnetic torque can be adjusted, thereby driving the prism carrier 10 to deflect and rotate relative to the mounting base 11, and / or driving the mounting base 11 to deflect and rotate relative to the first sub-housing 711, ultimately causing the prism 31 to deflect at a preset angle, changing the folding angle of the optical path, and realizing optical image stabilization compensation.

[0060] The first drive coil 13 can be fixed to the inner wall of the circuit board 9 by means of patch bonding or slot limiting. The first drive magnet 12 can be fixed to the prism carrier 10 and / or mounting base 11 by means of bonding or embedding. The magnetization direction of the first drive magnet 12 is adapted to the magnetic field direction of the first drive coil 13 to ensure the output efficiency of the driving force.

[0061] In this embodiment, by employing an electromagnetic drive scheme using a first driving coil 13 and a first driving magnet 12, high-precision, fast-response closed-loop adjustment of the prism 31's displacement can be achieved, improving the compensation accuracy and response speed of optical image stabilization, adapting to the shake compensation requirements of shooting scenarios, and ensuring imaging accuracy. Furthermore, the hierarchical movable support structure of the mounting base 11 and the prism carrier 10 provides stable structural support for the multi-dimensional displacement adjustment of the prism 31, ensuring the attitude stability of the prism 31 during image stabilization adjustment. This, in turn, improves focusing accuracy and imaging stability in telephoto shooting scenarios.

[0062] In one possible implementation, such as Figure 3As shown. The first driving magnet 12 includes an X-direction driving magnet 121 and a Y-direction driving magnet 122, and the first driving coil 13 includes an X-direction driving coil 131 and a Y-direction driving coil 132. The X-direction driving magnet 121 is disposed on the side wall of the mounting base 11 facing the inner side wall of the first sub-housing 711, and the X-direction driving coil 131 is disposed on the circuit board 9 at a position opposite to the X-direction driving magnet 121. The mounting base 11 is provided with a first groove for accommodating a ball bearing 14, which is used to rotate the mounting base 11 around the Y-axis under the drive of the X-direction driving magnet 121. The Y-direction driving magnet 122 is disposed on the end face of the prism carrier 10 facing the inner end face of the first sub-housing 711, and the Y-direction driving coil 132 is disposed on the circuit board 9 at a position opposite to the Y-direction driving magnet 122. The prism carrier 10 is provided with a boss 16, and the mounting base 11 is provided with a second groove 17. The second groove 17 is used to cooperate with the boss 16 so that the prism carrier 10 can rotate around the X axis under the drive of the Y-direction driving magnet 122.

[0063] The X-direction driving magnet 121 is disposed on the outer sidewall of the mounting base 11 facing the inner sidewall of the first sub-housing 711 in the X direction. The X-direction driving coil 131 is fixed on the circuit board 9 and arranged opposite to the X-direction driving magnet 121. The working surfaces of the X-direction driving coil 131 and the X-direction driving magnet 121 are parallel and opposite to each other, forming an electromagnetic engagement to drive the mounting base 11 to rotate around the Y-axis. The mounting base has a first groove on the sidewall opposite to the inner sidewall of the first sub-housing 711 in the Y direction. The first groove can be a spherical groove. Part of the ball 14 is embedded in the first groove, and the ball 14 contacts the inner sidewall of the first sub-housing 711 in the Y direction to rotatably support the mounting base 11 on the first sub-housing 711, forming a rolling support limiting structure. When a driving current is applied to the X-direction driving coil 131, the generated electromagnetic force acts on the X-direction driving magnet 121, forming a torque around the Y-axis to drive the mounting base 11 to rotate around the Y-axis. Multiple sets of ball bearings 14 can be arranged at intervals, and multiple sets of corresponding first grooves can also be arranged to improve the smoothness of the movement of the mounting base 11.

[0064] The Y-direction driving magnet 122 is disposed on the outer end face of the prism carrier 10 facing the inner end face of the first sub-shell 711 in the Y direction. The Y-direction driving coil 132 is fixed on the circuit board 9 and arranged opposite to the Y-direction driving magnet 122. The working surfaces of the Y-direction driving coil 132 and the Y-direction driving magnet 122 are parallel and opposite to each other, forming an electromagnetic engagement to drive the prism carrier 10 to rotate around the X-axis. The prism carrier 10 is provided with a boss 16, and the mounting base 11 is provided with a corresponding second groove 17 that mates with the boss 16. The second groove 17 and the boss 16 are fitted together to form a rotation support and limiting structure. When a driving current is applied to the Y-direction driving coil 132, the generated electromagnetic force acts on the Y-direction driving magnet 122, forming a torque around the X-axis to drive the prism carrier 10 to rotate around the X-axis. The cross-section of the boss 16 can be trapezoidal or arc-shaped, etc., and the cross-section of the second groove 17 is adapted to the boss 16 to ensure smooth rotation.

[0065] Optionally, the control circuits of the X-direction drive coil 131 and the Y-direction drive coil 132 are independent of each other, and independent drive currents can be applied to them respectively to realize individual adjustment or synchronous linkage adjustment in the X-axis and Y-axis directions.

[0066] In this embodiment, by cooperating with the X-direction drive coil 131 and the X-direction drive magnet 121, and with the Y-direction drive coil 132 and the Y-direction drive magnet 122, independent control of the prism 31's pitch and yaw rotation in both directions is achieved, improving the adjustment accuracy and control flexibility of optical image stabilization. Furthermore, the dual-axis independent drive structure enables more flexible image stabilization compensation strategies, adapting to the shake compensation needs of different shooting scenarios. Through the rolling guide structure of the ball bearing 14 and the first groove, and the sliding guide structure of the boss 16 and the second groove 17, precise axis positioning and degree-of-freedom limitation are provided for the rotation in both dimensions. This reduces motion friction resistance, improves the response speed and smoothness of angle adjustment, and strictly constrains the rotational posture of moving parts, ensuring the optical axis stability of the prism 31 during image stabilization adjustment and avoiding image degradation caused by optical axis deviation. This further improves the image clarity and stability in dynamic shooting and telephoto shooting scenarios.

[0067] In one possible implementation, such as Figures 4 to 5As shown. The focusing drive assembly includes: an imaging lens carrier 18 and a second drive magnet 19, with a second drive coil 20 disposed on a circuit board 9. The imaging lens carrier 18 is disposed within a second sub-housing 712, and the imaging lens 32 is disposed within the imaging lens carrier 18. The second drive magnet 19 is disposed on the sidewall of the imaging lens carrier 18 facing the inner sidewall of the second sub-housing 712, and the second drive coil 20 is disposed on the circuit board 9 at a position opposite to the second drive magnet 19. A third guide rail 23 is disposed inside the second sub-housing 712, and the imaging lens carrier 18 is provided with a third guide rail mating part 24 that mates with the third guide rail 23. The extending direction of the third guide rail 23 is parallel to the output optical axis.

[0068] An imaging lens carrier 18 is disposed within the second sub-housing 712, and the imaging lens carrier 18 has a hollow cylindrical structure. An imaging lens 32 is fixedly mounted within the hollow cavity of the imaging lens carrier 18, and the optical axis of the imaging lens 32 is coaxially aligned with the output optical axis of the imaging assembly 3. A second driving magnet 19 is fixed to the outer wall of the imaging lens carrier 18 facing the second driving coil 20. The second driving coil 20 is fixed to the circuit board 9 and arranged opposite to the second driving magnet 19. The working surfaces of the second driving coil 20 and the second driving magnet 19 are directly opposite each other, forming an axial electromagnetic drive pair. Multiple sets of the second driving coil 20 and the second driving magnet 19 can be arranged circumferentially to improve the uniformity of the driving force output and prevent uneven loading of the imaging lens carrier 18. A third guide rail 23 is fixedly disposed on the inner wall of the second sub-housing 712, and the extension direction of the third guide rail 23 is parallel to the output optical axis of the imaging assembly 3. A third guide rail mating part 24, adapted to and cooperating with the third guide rail 23, is correspondingly disposed on the outer wall of the imaging lens carrier 18. The third guide rail 23 and the third guide rail mating part 24 engage to form a sliding guide pair, which is used to constrain the movement trajectory of the imaging lens carrier 18 and limit its radial offset and circumferential deflection except for axial movement. At least one set of third guide rails 23 can be arranged at circumferential intervals along the second sub-housing 712, and the corresponding third guide rail mating parts 24 are arranged one-to-one with the third guide rails 23. The circuit of the second drive coil 20 is electrically connected to the circuit board 9 and can receive focus control signals. When a drive current is applied to the second drive coil 20, the drive magnetic field generated by the second drive coil 20 interacts with the permanent magnet magnetic field of the second drive magnet 19 to generate an electromagnetic driving force along the Z-axis. This can then drive the imaging lens carrier 18 to reciprocate linearly along the extension direction of the third guide rail 23, thereby driving the imaging lens 32 to adjust its axial position along the output optical axis, changing the axial distance between the imaging lens 32 and the image sensor 4, and realizing focus adjustment.

[0069] In this embodiment, the electromagnetic interaction between the second driving magnet 19 and the second driving coil 20 enables high-precision displacement adjustment of the imaging lens 32 along the output optical axis, improving focusing accuracy and speed in telephoto shooting scenarios. Furthermore, the sliding guide pair formed by the third guide rail 23 and the third guide rail mating part 24 constrains the movement trajectory of the imaging lens carrier 18, effectively preventing radial offset and circumferential deflection of the imaging lens 32 during focusing adjustment, ensuring the coaxiality of the optical axis of the imaging lens 32 with the output optical axis throughout the entire focusing stroke. This further improves driving efficiency and long-term operational reliability, enhancing the module's focusing performance and image clarity.

[0070] Figure 6 This is a schematic diagram of the structure of an electronic device with the periscope camera module in an extended state, according to an embodiment of this disclosure. Figure 7 This is a schematic diagram of the structure of an electronic device provided in this disclosure, where the periscope camera module is in a retracted state. Figures 6 to 7 As shown. The electronic device 200 includes an electronic device body 201 and a periscope camera module 100 as described in any of the above embodiments. The specific structure of the periscope camera module 100 can be referred to in the above embodiments.

[0071] The base 2 of the periscope camera module 100 is fixedly connected to the electronic device body 201 to realize the positioning and installation of the periscope camera module 100 inside the electronic device body 201, and to provide a stable support foundation for the telescopic movement of the periscope camera module 100.

[0072] The fixed end of the drive component of the periscope camera module 100 is assembled and fixed to the electronic device body 201. The electrical connection end of the drive component forms a stable electrical connection with the main control circuit of the electronic device body 201 to receive the drive control signal output by the electronic device body 201, thereby realizing the controllable adjustment of the reciprocating motion of the periscope camera module 100 housing 1 along the direction of the emitted optical axis.

[0073] The electronic device body 201 has through holes corresponding to the housing 1 of the periscope camera module 100. The cross-sectional dimension of the through holes is larger than or equal to the outer cross-sectional dimension of the housing 1, providing sufficient clearance for the reciprocating linear movement of the housing 1 relative to the electronic device body 201, allowing the housing 1 to smoothly switch between extended and retracted states through the through holes. When the periscope camera module 100 is in shooting mode, the housing 1 can be driven by the drive component to extend outward through the through holes, exposing the light-entry through holes on the housing 1 to the outside of the electronic device body 201, thus ensuring normal incident light from the outside. In non-shooting mode, the housing 1 can retract the imaging component 3 into the electronic device body 201, completing the module's storage.

[0074] The adaptive connection structure between the electronic device body 201 and the periscope camera module 100 ensures the stability of the module's telescopic movement, the reliability of the electrical connection, and the integrity of the optical path transmission, thereby enhancing the scene adaptability and user experience of the electronic device 200's shooting function. Furthermore, by incorporating the aforementioned axially telescopic periscope camera module 100, the electronic device 200 boasts a compact overall structure, effectively reducing its internal space occupation and aligning with the trend towards thinner and lighter designs. Simultaneously, the module assembly and integration process is relatively simple, reducing manufacturing costs.

[0075] The electronic device 200 provided in this embodiment can accommodate the layout requirements of a large-size photosensitive image sensor and a long-focal-length optical imaging system within a limited body thickness, alleviating the design limitations imposed by body thickness on the total length of the long-focal-length imaging optical path. In shooting mode, the extension of the housing 1 physically lengthens the axial length of the imaging optical path, improving image resolution and quality in long-focal-length shooting scenarios. In non-shooting mode, the retraction of the housing 1 allows for module storage, accommodating the slim and lightweight design requirements of the electronic device 200. This further enhances the scene adaptability and user experience of the electronic device 200's shooting function.

[0076] It should be noted that, depending on the implementation needs, the various components / steps described in the embodiments of this disclosure can be broken down into more components / steps, or two or more components / steps or parts of the operation of components / steps can be combined into new components / steps to achieve the purpose of the embodiments of this disclosure.
