Abstract
Description
Technical Field
[0001] This utility model relates to the field of image acquisition technology, and in particular to a camera device and electronic device. Background Technology
[0002] In related technologies, camera modules typically use voice coil motors to drive the lens structure for autofocus or optical image stabilization. However, when multiple camera modules are installed in an electronic device, and adjacent camera modules are placed close together, magnetic interference may occur between the magnets of the camera modules. This magnetic interference not only affects the driving performance of the voice coil motor, leading to problems such as inaccurate focusing and image stabilization failure, but also forces a sufficient safety distance to be maintained between the two camera modules, which is detrimental to the miniaturization design of electronic devices. Utility Model Content
[0003] This application discloses a camera device and electronic device that can form a magnetic interference-free adjacency interface between adjacent camera modules, thereby solving the magnetic interference problem caused by multiple camera modules being placed close together, and improving the space utilization rate of the camera module.
[0004] To achieve the above objectives, in a first aspect, this application discloses a camera device, comprising:
[0005] Multiple camera modules are arranged adjacent to each other along a first direction, and each camera module includes:
[0006] A lens structure having multiple circumferentially oriented lateral surfaces;
[0007] A power assembly includes a coil and a plurality of magnets, the plurality of magnets being respectively disposed on a portion of the peripheral side surface of the lens structure, the coil being disposed on the plurality of magnets, and the coil being used to cooperate with the magnets when energized to drive the lens structure to move along at least one of the first direction, the second direction, and the third direction.
[0008] In one of the multiple peripheral surfaces of a camera module, at least one peripheral surface is not provided with the magnet, and in two adjacent camera modules, the two peripheral surfaces that are not provided with the magnet face each other and are adjacent to each other;
[0009] The third direction is the optical axis direction, and the first direction, the second direction, and the third direction are perpendicular to each other.
[0010] As an optional implementation, the camera module further includes a magnetic shielding frame, which surrounds the outer periphery of the lens structure so that the plurality of magnets are located within the magnetic shielding frame.
[0011] By adding a magnetic shielding frame to the outer periphery of the lens structure of the camera module, and placing multiple magnets of the power component within this frame, the magnetic field generated by the magnets is effectively confined within the camera module by the shielding and binding effect of the magnetic field. In other words, the presence of the magnetic shielding frame reduces stray magnetic field leakage to the outside. Therefore, the magnetic shielding frame, by eliminating magnets on at least one peripheral side, further enhances the overall electromagnetic interference resistance of the camera device, protecting not only the stability of the camera module itself but also preventing potential interference to other surrounding electronic components.
[0012] As an optional implementation, the spacing between two adjacent camera modules along the first direction is greater than or equal to 0.5 mm.
[0013] By combining two technical solutions—the facing arrangement of the non-magnetic peripheral surfaces and the addition of a magnetic shielding frame—dual anti-magnetic interference protection is achieved. The peripheral surface layout primarily addresses magnetic field interference in the direction of adjacent interfaces, while the magnetic shielding frame absorbs and blocks stray magnetic fields leaking from other directions. This combined effect provides further magnetic field isolation. Therefore, the minimum spacing between two adjacent camera modules along the first direction can be further reduced to 0.5mm. When the camera module is used in electronic devices such as smartphones, more space can be reserved for other components such as batteries.
[0014] As an optional implementation, the spacing between two adjacent camera modules along the first direction is greater than or equal to 1 mm.
[0015] By arranging the non-magnetized peripheral surfaces of two adjacent camera modules facing each other, magnetic interference between the two adjacent camera modules can be effectively reduced or eliminated. This removes the physical distance between the two adjacent camera modules from the safety distance required for magnetic field interference, meaning the minimum distance can be reduced. Therefore, the camera device of this application can effectively control the minimum distance between two adjacent camera modules along the first direction to 1mm. This minimum distance enables a compact layout of multiple camera modules, thus facilitating the miniaturization and thinning of the camera device.
[0016] As an optional implementation, in one of the camera modules, there are three magnets and four peripheral surfaces, wherein each of the three peripheral surfaces is provided with a magnet. Of the three magnets, one magnet is configured as a focusing magnet and the other two magnets are configured as image stabilization magnets. The focusing magnet is configured to cooperate with the corresponding coil to drive the lens structure to move along the third direction, and the image stabilization magnet is configured to cooperate with the corresponding coil to drive the lens structure to move along the first direction and the second direction.
[0017] By employing an optimized configuration of three magnets within a single camera module and dividing the functions of these three magnets, the focusing and image stabilization functions required by the camera module can be fully retained while minimizing the number of magnets. For example, one focusing magnet drives the lens structure to move along a third direction to achieve the focusing function of the camera module, while the other two image stabilization magnets drive the lens structure to move along the first and second directions to achieve the image stabilization function of the camera module. Furthermore, compared to a four-magnet structure, the number of magnets used in the camera device of this application can be effectively reduced, thus lowering material costs. Therefore, the camera device of this application can solve the problem of maintaining focusing and image stabilization functions while reducing the number of magnets.
[0018] As an optional implementation, the lens structure includes an optical lens group, a carrier, and an image stabilization bracket. The carrier carries the optical lens group, and the image stabilization bracket is hollow inside to form a hollow portion. The image stabilization bracket is arranged around the outer periphery of the carrier so that the carrier is located in the hollow portion.
[0019] The image stabilization bracket has a plurality of peripheral side surfaces, wherein the focusing magnet is disposed on one of the peripheral side surfaces of the image stabilization bracket, and the image stabilization bracket has an opening communicating with the hollow portion on the peripheral side surface corresponding to the image stabilization magnet, and the image stabilization magnet is disposed on a portion of the surface of the carrier corresponding to the opening and is at least partially exposed to the opening.
[0020] The lens structure includes optical elements, a carrier, and an image stabilization bracket. The image stabilization bracket is hollow, forming a hollow section. The bracket surrounds the carrier, positioning it within the hollow section. This bracket not only provides support for the carrier but also a stable mounting reference for the image stabilization magnet, ensuring the accuracy of the optical elements' movement. Furthermore, the image stabilization magnet has an opening on its peripheral side that connects to the hollow section. This opening provides ample space for the carrier to move during image stabilization adjustments, preventing structural interference between the magnet and internal components, thus ensuring the reliability and stability of the image stabilization mechanism.
[0021] As an optional implementation, the anti-shake bracket is provided with a guide groove extending along the third direction, and the carrier is slidably disposed in the guide groove by ball bearings, the guide groove being configured to guide the movement of the carrier in the third direction.
[0022] By utilizing the rolling friction of ball bearings instead of sliding friction, the resistance to the carrier's movement along a third direction (optical axis) is reduced, resulting in a smoother motion. Simultaneously, the guide groove provides precise linear guidance for the carrier, ensuring stable movement along the optical axis during focusing and preventing deflection or tilting. Therefore, the solution of incorporating guide grooves on the image stabilization bracket and multiple ball bearings between the guide grooves and the carrier effectively solves the potential jamming problem that may occur in the lens structure during autofocus, significantly improving the focusing speed and response sensitivity of the power unit, thereby enhancing the performance of the camera module.
[0023] As an optional implementation, in one of the camera modules, the coil is arranged around the outer periphery of the lens structure, and the coil includes a plurality of sub-parts connected sequentially along the circumference of the lens structure, and the plurality of sub-parts are respectively arranged in a one-to-one correspondence with a plurality of magnets.
[0024] By designing the coil of the power component as multiple sub-parts connected sequentially along the circumference of the lens structure, and setting each of the multiple sub-parts to correspond one-to-one with a multiple of the magnets, this arrangement can integrate the coils that originally needed to be wound independently into one component. Compared with the solution of multiple independent coils, the integrated structure reduces the number of components and welding points, simplifies the assembly process, and solves the problems of complex assembly and poor consistency of split coils. This is beneficial to improving the production efficiency and product yield of the camera module.
[0025] As an optional implementation, the camera device further includes a circuit board, with multiple camera modules sharing the same circuit board.
[0026] By sharing a single circuit board for multiple camera modules, the control circuitry, power management, and signal transmission paths of these modules can be integrated into a unified control system, facilitating unified control of the camera modules. Compared to a solution where each camera module has its own independent circuit board, sharing a circuit board reduces the amount of board material used and the number of inter-board connectors, thereby lowering the hardware cost of the camera device and improving the flexibility and integration of electronic component layout.
[0027] Secondly, this application also discloses an electronic device, which includes a camera device as described in the first aspect.
[0028] The camera device's non-magnetic side-facing core design allows for a compact arrangement of multiple camera modules within the electronic device, providing more usable space for industrial design. Furthermore, the internal space saved by the camera device can be used to configure larger capacity batteries or better heat dissipation systems, thereby improving the overall space utilization and comprehensive performance of the electronic device.
[0029] Compared with the prior art, the beneficial effects of this application are:
[0030] This application provides a camera device that designs the power components of multiple camera modules to have magnets only on some of their peripheral surfaces, so that at least one peripheral surface in each camera module is free of magnets. These two non-magnetic peripheral surfaces are arranged facing each other and adjacent to each other between two adjacent camera modules. This arrangement creates a magnetically interference-free interface between adjacent camera modules, structurally solving the magnetic interference problem caused by the close proximity of multiple camera modules in existing technologies. Therefore, the camera device of this application can solve the problem of performance degradation due to magnetic interference when pursuing compact arrangement of multiple camera modules in existing camera devices, and also facilitates the miniaturization design of electronic devices.

Detailed Implementation
[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0047] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.
[0048] As described in the background section of this application, multiple camera modules are typically integrated into electronic devices such as smartphones to achieve diverse shooting functions. When these camera modules are arranged close together, the power components (usually containing magnets) inside them that drive the lens structure can generate mutual magnetic interference, affecting the performance of autofocus or optical image stabilization.
[0049] In addition, in order to avoid this magnetic interference, the common solution adopted by related technologies is to reserve a sufficient safety distance, which results in the camera area occupying too much internal space.
[0050] Based on this, this application discloses a camera device and electronic device. By designing the power component of the camera module, a non-magnetic peripheral side is formed on each camera module. By arranging the non-magnetic peripheral sides of adjacent camera modules facing each other, and by utilizing the characteristics of the magnetic shielding frame, the magnetic field interference at the adjacent interface is structurally reduced or even eliminated. This allows the arrangement of multiple camera modules to be more compact, thereby improving the space utilization rate between multiple camera modules.
[0051] The camera device and electronic device of this application will be described in detail below with reference to the accompanying drawings.
[0052] Please refer to the following: Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of a camera device 100 provided in an embodiment of this application. Figure 2 This is a top view of the camera module in the camera device disclosed in the embodiments of this application. Figure 3 yes Figure 2 A cross-sectional view of the camera module in the AA direction. Figure 4 yes Figure 2The image is a cross-sectional view of the camera module in the BB direction. The camera device 100 includes: a plurality of camera modules 2, wherein the plurality of camera modules 2 are arranged adjacently along a first direction F1. Each camera module 2 includes a lens structure 20 and a power assembly 21. The lens structure 20 has a plurality of circumferential surfaces 201 along the circumferential direction. The power assembly 21 includes a coil 210 and a plurality of magnets 211. The plurality of magnets 211 are respectively arranged corresponding to a portion of the circumferential surfaces 201 of the lens structure 20. The coil 210 is arranged corresponding to the plurality of magnets 211. When energized, the coil 210 cooperates with the magnets 211 to drive the lens structure 20 to move along at least one of the first direction F1, the second direction F2, and the third direction F3. In one camera module 2, at least one circumferential surface 201 is not provided with a magnet 211, and in two adjacent camera modules 2, the two circumferential surfaces 201 without magnets 211 face each other and are arranged adjacently.
[0053] The third direction F3 is the optical axis direction, and the first direction F1, the second direction F2, and the third direction F3 are all perpendicular to each other.
[0054] Specifically, the camera module 2 includes a housing 1 and a base 11. As a basic support structure, the installation space 10 formed inside the housing 1 and base 11 provides a basic accommodating environment for multiple camera modules 2, allowing them to be installed and ensuring their stability. In each camera module 2, multiple peripheral surfaces 201 of the lens structure 20 provide a basis for the installation of magnets 211. However, the coil 210 of the power assembly 21 does not correspond to all peripheral surfaces 201 of the lens structure 20, but is only installed on some of them. This means that each camera module 2 necessarily has at least one peripheral surface 201 without a magnet 211. Furthermore, by placing the peripheral surfaces 201 without magnets 211 facing each other and adjacent to each other in two adjacent camera modules 2, a magnetic interference-free interface is formed at the junction of the two camera modules 2. This magnetic interference-free interface eliminates the magnetic interference problem of the voice coil motor when multiple camera modules 2 are placed close together. This eliminates the need for excessive anti-interference space between camera modules 2, allowing for a reduction in the overall size of the camera device 100 and making it suitable for the thinner and lighter design of mobile phones and other electronic devices 200.
[0055] Meanwhile, the non-magnetic interference interface can also ensure the accuracy of the lens structure 20 when it moves along the first, second, and third directions F3 under the drive of the power component 21, avoid driving deviation caused by magnetic interference, ensure stable shooting performance, and even allow the electronic device 200 to integrate more camera modules 2 in a limited space, thereby improving the diversity and competitiveness of the product's shooting functions.
[0056] Understandably, camera devices typically consist of a main camera and multiple secondary cameras, and not every camera needs to be equipped with physical image stabilization. For camera modules 2 that lack image stabilization, a design can be used, for example, with a focusing magnet on one side and no corresponding magnets on the other sides. In this approach, the non-magnetic sides of such camera modules 2 can be joined together with the non-magnetic sides of other camera modules 2, allowing for combinations of three, four, or more camera modules 2, effectively avoiding mutual interference between magnetic fields. This design enables multiple camera modules 2 to be tightly integrated, satisfying the device's needs for different shooting functions while ensuring that each camera module 2 operates independently without interfering with the others.
[0057] It is understandable that the number of peripheral side surfaces 201 of the lens structure 20 can be adjusted according to the overall outline design of the camera module 2, such as three, four or other reasonable numbers, and is not limited to a specific number.
[0058] In some embodiments, the camera device 100 also includes a circuit board 3, which can be shared by the multiple camera modules 2. Sharing the same circuit board 3 allows the control circuitry of each camera module 2 to be integrated. For example, the control chip, power management circuitry, and signal transmission circuitry of the drive coil 210 can be integrated onto the same circuit board 3, forming a unified system. This helps avoid signal interference between the independent circuit boards 3 of each camera module 2. Compared to a design where each camera module 2 has its own independent circuit board 3, this design eliminates the need for a separate substrate for each camera module 2, thus reducing the amount of circuit board material used. Furthermore, because signal and power transmission between multiple boards does not require connectors, the number of inter-board connectors is also reduced, thereby lowering the hardware cost of the camera device 100.
[0059] Meanwhile, the integrated circuit board 3 has a more flexible layout, and the shape of the board and the circuit routing can be adjusted according to the arrangement of multiple modules, which improves the utilization of the internal space of the camera device 100, and can also reduce signal loss and delay caused by inter-board connections, ensuring the synchronization of the driving of each module coil 210.
[0060] It is understood that, as another embodiment, multiple camera modules may not share a circuit board, but each camera module may have its own circuit board.
[0061] In some embodiments, such as Figures 1 to 5 As shown, along the first direction F1, the distance between two adjacent camera modules 2 is greater than or equal to 1mm.
[0062] In this embodiment, the arrangement of adjacent camera modules 2 with their peripheral surfaces 201 facing each other without magnets 211 structurally reduces or eliminates the magnetic force between the two camera modules 2, so that the physical distance between the camera modules 2 is no longer limited by the safety distance required for magnetic field interference. Therefore, the distance between two adjacent camera modules 2 along the first direction F1 can be set to greater than or equal to 1mm. This distance ensures that the two camera modules 2 do not collide physically during assembly, transportation, and use, and also significantly reduces the overall space occupied by the multi-camera setup. This achieves a miniaturized and thinner design of the camera device 100, adapting to the stringent internal space requirements of smartphones and other electronic devices 200. For example, the camera area of a smartphone can be reduced along the width of the smartphone, thereby improving the overall grip or reserving more installation space 10 for other core components.
[0063] In some embodiments, such as Figures 1 to 5 As shown, the camera module 2 also includes a magnetic shielding frame 22, which surrounds the outer periphery of the lens structure 20 so that multiple magnets 211 are located in the magnetic shielding frame 22.
[0064] Specifically, a magnetic shielding frame 22 is provided around the lens structure 20 of each camera module 2 to ensure that all magnets 211 of the power component 21 are located inside the magnetic shielding frame 22. By utilizing the shielding and confining properties of the magnetic shielding frame 22, the magnetic field generated by the magnets 211 is firmly confined inside the camera module 2, reducing stray magnetic field leakage into the external space. Combined with the basic layout of the peripheral surfaces 201 of adjacent camera modules 2 facing each other without magnets, a dual protective structure of non-magnetic adjacent interfaces and internal magnetic field confinement is formed, further enhancing the magnetic field isolation between adjacent camera modules 2.
[0065] Therefore, adding a magnetic shielding frame 22 to the camera module 2 can not only more stably ensure the driving accuracy of the lens structure 20 when it moves along the first direction F1, the second direction F2 and the third direction F3, avoiding focus shift or image stabilization failure caused by magnetic interference, but also prevent the magnetic field of the magnet 211 from spreading to other electronic components around the camera device 100 (such as radio frequency antennas and battery management chips), avoiding problems such as signal attenuation and unstable power supply caused by the magnetic field, thus improving the overall operational reliability of the electronic device 200.
[0066] It is understandable that the enclosure shape of the magnetic shielding frame 22 can be adjusted according to the outer contour of the lens structure 20. For example, when the periphery 201 of the lens structure 20 is quadrilateral, the magnetic shielding frame 22 can be designed as a square closed loop. When the periphery 201 of the lens structure 20 is an arc-shaped segment, polygon, or other shape, the magnetic shielding frame 22 can be set with an enclosure segment of a similar shape.
[0067] In some embodiments, such as Figures 1 to 5 As shown, along the first direction F1, the distance between two adjacent camera modules 2 is greater than or equal to 0.5mm.
[0068] In this embodiment, the magnetic field interference problem between adjacent interfaces is solved because the peripheral surfaces 201 of the multiple camera modules 2, which are not equipped with magnets, are arranged facing each other. The magnetic shielding frame 22 also blocks stray magnetic field leakage from other directions. The combination of the two solutions forms a dual anti-magnetic interference protection, thereby greatly improving the magnetic field isolation effect. This allows adjacent modules to avoid interference without relying on excessively large spacing. Therefore, the spacing between two adjacent camera modules 2 along the first direction F1 can be compressed to greater than or equal to 0.5mm. This spacing ensures that the two modules do not collide physically during assembly and use. At the same time, it avoids thermal expansion and contraction caused by changes in ambient temperature, which would cause the outer shell 1 between the two adjacent camera modules 2 to expand and squeeze. It also maximizes the compression of the space occupied by multiple cameras, thereby reserving more internal space for electronic devices such as smartphones 200. This saved internal space can be used to configure larger capacity batteries, more efficient heat dissipation modules (to prevent the device from overheating), or integrate other functional components (such as macro lenses). At the same time, it can maintain the accuracy of the lens structure 20 in all directions and avoid structural interference caused by excessively small spacing.
[0069] In some embodiments, such as Figures 1 to 5 As shown, this application takes two camera modules as an example, and both camera modules are camera modules with image stabilization function.
[0070] Optionally, the housing 1 of the camera module can be generally square, that is, the housing 1 has approximately four circumferential sides. Then, in a camera module 2, there can be three magnets 211, and the circumferential sides 201 include four, such as... Figure 3 and Figure 4 As shown, each of the three peripheral surfaces 201 is provided with a magnet 211, and one of the three magnets 211 is configured as a focusing magnet 2111. Figure 4 The left side of the cross-section of the camera module), the other two magnets are configured as image stabilization magnets 2112 ( Figure 3 and Figure 4 (The right side of the cross-section of the camera module) The focusing magnet 2111 is configured to cooperate with the corresponding coil 210 to drive the lens structure 20 to move along the third direction F3, and the image stabilization magnet 2112 is configured to cooperate with the corresponding coil 210 to drive the lens structure 20 to move along the first direction F1 and the second direction F2.
[0071] In this embodiment, the lens structure 20 of each camera module 2 has four peripheral side surfaces 201, and magnets 211 are provided on only three of the peripheral side surfaces 201, and the three magnets can be a focusing magnet 2111 and two image stabilization magnets 2112 respectively.
[0072] Since the image stabilization magnet 2112 needs to drive the lens structure 20 to move in the mutually perpendicular first direction F1 and second direction F2, in order to ensure that the lens structure 20 is subjected to uniform force and responds sensitively during image stabilization, the two image stabilization magnets 2112 need to be adjacent and perpendicularly distributed. This distribution allows the lens to remain stable during image stabilization movement and avoids additional shaking caused by uneven force. The focusing magnet 2111 needs to generate a driving force along the third direction F3, so it is set on the peripheral side 201 perpendicular to the plane where the image stabilization magnet 2112 is located. This can avoid magnetic field interference between the focusing magnet 2111 and the image stabilization magnet 2112, and also ensure that the focusing driving force does not affect the image stabilization function.
[0073] Furthermore, the focusing magnet 2111 cooperates with the corresponding coil 210, and when energized, it generates a driving force along the third direction F3 (optical axis direction), thereby driving the lens structure 20 to move along the optical axis to achieve autofocus; the two image stabilization magnets 2112 cooperate with the corresponding coils 210 respectively, and when energized, they can generate driving forces along the first direction F1 and the second direction F2 respectively, thereby driving the lens structure 20 to move in these two directions to achieve optical image stabilization.
[0074] Compared to the four-magnet solution, this solution retains autofocus and optical image stabilization functions completely while eliminating one magnet. Furthermore, the reduced number of magnets not only lowers material costs but also reduces the magnetic field sources around camera module 2, further minimizing magnetic interference between adjacent camera modules 2.
[0075] In some embodiments, the lens structure 20 includes an optical lens group 202, a carrier 203, and an image stabilization bracket 204. The carrier 203 carries the optical lens group 202. The image stabilization bracket 204 is hollow inside to form a hollow portion 2041, and the image stabilization bracket 204 surrounds the outer periphery of the carrier 203 so that the carrier 203 is located in the hollow portion 2041.
[0076] The image stabilization bracket 204 has multiple peripheral side surfaces 201, wherein a focusing magnet 2111 is disposed on one of the peripheral side surfaces 201 of the image stabilization bracket 204, and an opening 2042 communicating with the hollow portion 2041 is provided on the peripheral side surface 201 corresponding to the image stabilization magnet 2112 on the image stabilization bracket 204, and the image stabilization magnet 2112 is disposed on a portion of the surface of the carrier 203 corresponding to the opening 2042 and is at least partially exposed to the opening 2042.
[0077] Specifically, the carrier 203 in the lens structure 20 supports the optical lens group 202, ensuring that the optical lenses maintain a fixed relative position to guarantee image sharpness. The image stabilization bracket 204 has a hollow interior forming a hollow section 2041, which surrounds the outer periphery of the carrier 203, thus providing a stable support frame for the carrier 203 and preventing the carrier 203 from shifting during movement, thereby ensuring the movement accuracy of the lens structure 20.
[0078] Meanwhile, the multiple peripheral surfaces 201 of the image stabilization bracket 204 provide a foundation for the installation of the magnet 211. The focusing magnet 2111 is set on one of the peripheral surfaces 201 of the image stabilization bracket 204, while the peripheral surface 201 on which the image stabilization magnet 2112 is set has an opening 2042 that connects to the hollow part 2041. The image stabilization magnet 2112 is installed on a part of the surface of the carrier 203 corresponding to the opening 2042 and is at least partially exposed. This design allows the image stabilization magnet 2112 to avoid contact with the image stabilization bracket 204 through the opening 2042 when the carrier 203 drives the optical lens group 202 to perform image stabilization displacement along the first direction F1 or the second direction F2, thereby avoiding structural interference and ensuring the normal operation of the image stabilization movement.
[0079] Understandably, the shape of the opening 2042 can be adapted to the shape design of the anti-shake magnet 2112, such as square or round, but all must ensure that the anti-shake magnet 2112 is partially exposed and does not obstruct displacement.
[0080] In some embodiments, please refer to Figures 2 to 6 The image stabilization bracket 204 is provided with a guide groove 205 extending along the third direction F3. The carrier 203 is slidably disposed in the guide groove 205 by means of ball bearings 206. The guide groove 205 is configured to guide the movement of the carrier 203 in the third direction F3.
[0081] Specifically, the image stabilization bracket 204 and the base 11 of the housing 1 share a guide groove 205 extending along the third direction F3. That is, the image stabilization bracket 204 has half a guide groove 205, and the base 11 has half a guide groove 205, together forming a complete guide groove 205. This guide groove 205 provides path constraints for the movement of the carrier 203 along the third direction F3. The carrier 203 is placed on the image stabilization bracket 204, and the optical lens group 202 is mounted on the carrier 203. Therefore, the focusing function of the optical lens group 202 is achieved by the displacement of the carrier 203 along the third direction F3 under the guidance of the image stabilization bracket 204. The ball bearing 206, in cooperation with the guide groove 205, converts the sliding friction between the base 11 and the image stabilization bracket 204 into rolling friction, significantly reducing the movement resistance of the carrier 203. This makes the movement of the image stabilization bracket 204 smoother along the third direction F3, avoiding focusing stuttering.
[0082] Meanwhile, the extension direction of the guide groove 205 strictly conforms to the third direction F3, which can provide precise linear guidance for the carrier 203, ensuring that the carrier 203 does not deflect or tilt when it drives the optical lens group 202 to move along the optical axis, thereby ensuring the accuracy of autofocus. The design of the ball bearing 206 and the guide groove 205, together with the focusing magnet 2111, not only solves the problem of easy jamming in sliding cooperation, but also improves the focusing speed and response sensitivity, allowing the lens structure 20 to quickly and accurately reach the target position when focusing, further enhancing the shooting performance of the camera module 2, and also reducing component wear, thereby extending the service life of the camera module 2.
[0083] It is understandable that the number of guide grooves 205 can be adjusted according to the size, weight and other requirements of the camera module 2, such as symmetrical arrangement at the corners of the camera module 2 or arrangement on a single side.
[0084] In some embodiments, in a camera module 2, a coil 210 is arranged around the outer periphery of a lens structure 20. The coil 210 includes a plurality of sub-parts 2101 connected sequentially along the circumference of the lens structure 20. The plurality of sub-parts 2101 are respectively arranged in a one-to-one correspondence with a plurality of magnets 211.
[0085] Specifically, in a camera module 2, a coil 210 is arranged around the outer periphery of the lens structure 20. The area around the coil 210 covers the area of the circumferential side 201 where the magnet 211 is located, ensuring that the coil 210 and the magnet 211 can form an effective magnetic field. Furthermore, the coil 210 is designed as multiple sequentially connected sub-parts 2101 along the circumference of the lens structure 20, and the number of sub-parts 2101 matches the number of magnets 211 in the camera module 2. Each sub-part 2101 corresponds to one magnet. This integrates multiple independent coils 210 that would otherwise require separate processing and installation into a single structure, avoiding positional deviations that can easily occur when installing individual coils 210.
[0086] Meanwhile, by integrating multiple independent coils 210 into a single structure, it is no longer necessary to solder each independent coil 210 onto the circuit individually, thereby reducing the number of coil 210 components and soldering points, and simplifying the assembly process of the camera module 2. This design not only solves the problem of poor consistency during the assembly of independent coils, but also reduces the risk of poor soldering and desoldering caused by too many soldering points, which is conducive to improving production efficiency and product yield. At the same time, the integrated coil 210 has stronger structural stability, and can always maintain the precise relative position of each sub-part 2101 and the corresponding magnet 211, avoiding uneven driving force caused by coil 210 offset, and ensuring the driving accuracy and response stability of the lens structure 20 when moving along the first direction F1, the second direction F2, and the third direction F3.
[0087] This application also provides an electronic device 200, please refer to [link to relevant documentation]. Figure 7 The electronic device 200 includes the aforementioned camera device 100.
[0088] It is understood that electronic devices may include, but are not limited to, smartphones, tablets, laptops, and drones.
[0089] Taking a smartphone as an example, the camera device 100 is integrated into the camera area of the electronic device 200 (such as the camera module 2 mounting area on the back of the smartphone). Simultaneously, the circuit board 3 of the camera device 100 is electrically connected to the motherboard of the electronic device 200 via a ribbon cable or connector, enabling the device to supply power and control signals to the camera device 100. Because the camera device 100 features a core design where the peripheral sides 201 of adjacent camera modules 2 (without magnets) face each other and are adjacent, a compact arrangement of multiple camera modules 2 can be achieved. Compared to cameras with four-sided magnet modules, this reduces the space occupied by the camera area inside the electronic device 200, thus saving more internal space. Therefore, the electronic device 200 not only optimizes its internal layout due to improved space utilization, but the compact camera arrangement also makes the appearance of the electronic device 200 simpler, thereby improving the overall product performance of the electronic device 200.
