Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to a camera module and electronic device. Background Technology

[0002] Cameras in electronic products such as laptops, tablets, and mobile phones need to have multiple degrees of freedom to meet functions such as autofocus and optical image stabilization, thereby improving the quality and effect of captured images or videos. Currently, camera driving is usually achieved through motors, which can achieve translation in space.

[0003] In existing technology, motors used to drive cameras include magnets and coils. The magnets are typically connected to the camera, and the coils are typically connected to a fixed structure of the electronic product. The positional relationship between the magnet and the coil ensures that when the coil is energized, the magnet and coil can generate relative displacement, thereby allowing the camera to move relative to the housing. The magnets are configured as bipolar magnets. Specifically, if the magnet and the coil are positioned opposite each other in the Z-axis, the magnet has N and S poles at both ends in the Y-axis perpendicular to the Z-axis. The N and S poles located at the same end of the magnet in the Y-axis are positioned opposite each other in the Z-axis. To reduce magnetic resistance along the magnetic field lines, a magnetic guide plate is placed on the side of the magnet facing away from the coil, and the magnetic guide plate is spaced apart from the magnet. The placement of the magnetic guide plate results in a larger motor size in the Z-axis direction. Since the thickness of electronic devices is usually in the same direction as the Z-axis, the placement of the magnetic guide plate increases the thickness of the electronic device.

[0004] Therefore, there is an urgent need for a miniaturized camera module and electronic device. Utility Model Content

[0054] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0055] This embodiment provides a camera module that has a small thickness, meeting the requirements for thinness and lightness.

[0056] For example, such as Figures 1 to 13As shown, the camera module includes a housing 100, a camera 200, and an image stabilization drive mechanism 300. The housing 100 has a lens hole 110. For ease of description, in this embodiment, the length direction of the housing 100 can be defined as the second direction Y, the width direction as the third direction Z, and the thickness direction as the first direction X. That is, any two of the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The length and width of the housing 100 can be the same, in which case the housing 100 is square. Typically, the length of the housing 100 is greater than its width. In this embodiment, the lens hole 110 is located on one of the housing walls in the thickness direction of the housing 100.

[0057] In some alternative embodiments, such as Figure 2 As shown, the lens hole 110 is formed in the first shell wall 120 of the housing 100. One end of the camera 200 is located inside the housing 100, and the other end extends out of the housing 100 through the lens hole 110.

[0058] For example, such as Figure 2 and Figure 3 As shown, the image stabilization drive mechanism 300 includes a magnet assembly 310 and a coil assembly 320. The magnet assembly 310 and the coil assembly 320 are disposed opposite to each other in a first direction X. The camera 200 is connected to one of the magnet assembly 310 and the coil assembly 320, and the other of the magnet assembly 310 and the coil assembly 320 is connected to the housing 100. Exemplarily, in this embodiment, the magnet assembly 310 is fixedly connected to the camera 200, and the coil assembly 320 is fixedly connected to the housing 100. The magnet assembly 310 includes a ring-shaped Hellbeck array. The Hellbeck array is fitted onto the camera 200. The coil assembly 320 is disposed on the magnetic field enhancement side of the Hellbeck array.

[0059] For ease of understanding, this embodiment describes the Hellbeck array, a magnetic structure that achieves directional enhancement of the magnetic field through a special arrangement of magnets. Specifically, the core principle of the Hellbeck array is to use a special arrangement of permanent magnets to significantly enhance the magnetic field on one side while almost eliminating it on the other. In this embodiment, the side with enhanced magnetic field is referred to as the magnetic field enhancement side, and the other side as the weak magnetic field side. For example, in... Figure 4 The magnet assembly 310 in the shown orientation has a magnetic field enhancement side above it and a weak magnetic field side below it. The design of the Hellbeck array requires periodic changes in the magnetization directions of adjacent magnets to achieve directional enhancement through magnetic field superposition and cancellation effects.

[0060] In this embodiment, the coil assembly 320 includes a plurality of anti-shake coils 321, which are spaced apart around the periphery of the camera 200 along the circumferential direction of the camera 200. Each anti-shake coil 321 is configured to cooperate with the Helbeck array to drive the magnet assembly 310 and the coil assembly 320 to move relative to each other in the anti-shake direction of the camera 200, thereby realizing the anti-shake function of the camera module.

[0061] The camera module provided in this embodiment includes an image stabilization drive mechanism 300 for implementing the image stabilization function of the camera module. The image stabilization drive mechanism 300 includes a magnet assembly 310 and a coil assembly 320. The magnet assembly 310 includes a Heilbeck array, which gives the magnet assembly 310 a magnetic field enhancement side. By placing the coil assembly 320 on the magnetic field enhancement side, the coil assembly 320 and the magnet assembly 310 can generate a large driving force. Therefore, it is not necessary to set a magnetic guide plate on the side of the magnet assembly 310 facing away from the coil assembly 320. This makes the size of the image stabilization drive mechanism 300 smaller in the first direction X, and thus the thickness of the housing 100 smaller, which is beneficial for the miniaturization and thinning of the camera module.

[0062] In this embodiment, by setting multiple anti-shake coils 321 and winding them around the periphery of the camera 200, the camera 200 can be driven in the second direction Y and the third direction Z, making the anti-shake adjustment of the camera 200 more flexible.

[0063] For example, such as Figures 6 to 10 As shown, the magnet assembly 310 includes multiple first main magnets 311, multiple second main magnets 312, and multiple auxiliary magnets 313 arranged in the same layer. The first main magnets 311 and second main magnets 312 have opposite polarities. For example, the first main magnet 311 may be an N magnet and the second main magnet 312 a S magnet; alternatively, the first main magnet 311 could also be an S magnet and the second main magnet 312 an N magnet. It should be noted that the arrangement of multiple first main magnets 311, multiple second main magnets 312, and multiple auxiliary magnets 313 in the same layer can be understood as the top (or bottom) surfaces of all three magnets being located on the same plane. This design ensures that the overall thickness of the magnet assembly 310 is not too large, meaning that the size of the magnet assembly 310 in the first direction X is not excessive, facilitating miniaturization and allowing for a thinner camera module.

[0064] like Figure 7As shown, multiple first main magnets 311 and multiple second main magnets 312 are alternately arranged along a first circumferential direction. A secondary magnet 313 is provided between any adjacent first main magnet 311 and second main magnet 312 along the first circumferential direction, so that the first main magnets 311, second main magnets 312, and secondary magnets 313 cooperate to form a Hellbeck array. It should be noted that one or more secondary magnets 313 may be provided between the first main magnet 311 and second main magnet 312. In this embodiment, one secondary magnet 313 is provided between the first main magnet 311 and the second main magnet 312. It should be noted that in this embodiment, the circumferential direction of the Hellbeck array is referred to as the first circumferential direction.

[0065] It should be noted that, in order to form the Heilbeck array, the magnetization directions of the first main magnet 311 and the secondary magnet 313, which are adjacent upwards in the first ring, are different; specifically, they are perpendicular to each other. Similarly, the magnetization directions of the second main magnet 312 and the secondary magnet 313 are also different, specifically, they are perpendicular to each other. Optionally, the magnetization directions of the first main magnet 311 and the second main magnet 312 are opposite, that is, the magnetization direction of the first main magnet 311 is opposite to the magnetization direction of the second main magnet 312.

[0066] Optionally, the first main magnet 311 is a magnet that releases magnetic field lines outward, and the magnetization direction of the auxiliary magnet 313 located between the first main magnet 311 and the second main magnet 312 is towards the first main magnet 311, so as to form a Heilbeck array. It is understood that the magnetization direction of the auxiliary magnet 313 located between the first main magnet 311 and the second main magnet 312 can also be towards the second main magnet 312, in which case the second main magnet 312 is a magnet that releases magnetic field lines outward; this embodiment does not limit this.

[0067] Optionally, the first main magnet 311 is a magnet that releases magnetic field lines outward. The magnetization direction of the auxiliary magnet 313 located between the first main magnet 311 and the second main magnet 312 is towards the first main magnet 311, and the magnetization direction of the first main magnet 311 is towards the first housing wall 120, with the image stabilization coil 321 located on the side of the auxiliary magnet 313 facing the first housing wall 120. With this configuration, the magnetic field enhancement side of the first main magnet 311 faces the first housing wall 120. The first housing wall 120 through which the camera 200 passes is typically located near the outer surface of the electronic device and usually does not house magnetic components. Therefore, the influence on other magnetic components can be reduced, and other magnetic components will not affect the magnetic field of the magnet assembly 310, further improving the imaging effect and reliability of the camera module.

[0068] In this embodiment, the coil assembly 320 is located on the magnetic field enhancement side of the Hellbeck array and is spaced apart from the magnet assembly 310. When energized, the coil assembly 320 interacts with the magnet assembly 310, and the coil assembly 320 and the magnet assembly 310 move relative to each other. Thus, the camera 200 is connected to the coil assembly 320 or the magnet assembly 310, and the coil assembly 320 or the magnet assembly 310 can drive the camera 200 to move, thereby achieving the corresponding function. It should be noted that the special arrangement of the magnets in the Hellbeck array is equivalent to reducing the magnetic circuit resistance on the magnetic field enhancement side of the Hellbeck array, allowing more magnetic lines of force to pass through the magnetic field enhancement side.

[0069] The image stabilization drive mechanism 300 provided in this embodiment consists of a first main magnet 311, a second main magnet 312, and a secondary magnet 313 of the magnet assembly 310, which cooperate to form a Hellbeck array. This allows the magnetic field strength of the magnet assembly 310 to be concentrated on one side, meaning the magnetic field strength on the enhanced side of the magnet assembly 310 is greater than that on the opposite side. The coil assembly 320 is located on the enhanced side of the Hellbeck array. On the one hand, this reduces the magnetic circuit resistance, thereby increasing the interaction force between the magnet assembly 310 and the coil assembly 320, resulting in a larger thrust generated by the image stabilization drive mechanism 300. On the other hand, the magnet assembly 310 has a weak magnetic field side. Placing other magnetic components of the electronic device close to the weak magnetic field side of the magnet assembly 310 can reduce the influence and interference of the image stabilization drive mechanism 300 on these magnetic components. It also avoids interference from other magnetic components on the image stabilization drive mechanism 300, ensuring that both the image stabilization drive mechanism 300 and the magnetic components can work normally, resulting in high reliability and enabling the camera module to achieve high image quality.

[0070] Optionally, when the electronic device has two anti-shake drive mechanisms 300, the weak magnetic field sides of the two anti-shake drive mechanisms 300 are arranged facing each other, and the two magnetic field enhancement sides are arranged opposite each other, so as to reduce the mutual influence and interference between the two anti-shake drive mechanisms 300.

[0071] In this embodiment, by setting the magnet assembly 310 in a ring shape, the size of the magnet assembly 310 in the length or width direction of the image stabilization drive mechanism 300 is not too large, which is conducive to the miniaturization of the image stabilization drive mechanism 300. It can also set more first main magnets 311, secondary magnets 313 and second main magnets 312 in a limited space, thereby providing a larger driving force to suit the heavier camera 200.

[0072] In some alternative embodiments, such as Figure 9As shown, each image stabilization coil 321 and the magnet assembly 310 at least partially overlap in the first direction X, that is, each image stabilization coil 321 is at least partially opposite to the magnet assembly 310 in the first direction X. It should be noted that the at least partial overlap of each image stabilization coil 321 and the magnet assembly 310 in the first direction X can be understood as follows: the projection of the image stabilization coil 321 along the first direction X onto a plane perpendicular to the first direction X at least partially overlaps with the projection of the magnet assembly 310 along the first direction X onto a plane perpendicular to the first direction X. In other words, the image stabilization coil 321 is not offset from the magnet assembly 310 in the first direction X.

[0073] By setting each stabilization coil 321 to at least partially overlap with the magnet assembly 310 in the first direction X, the space on one side of the magnet assembly 310 in the first direction X can be fully utilized. Compared with the staggered arrangement, the length and width of the stabilization drive mechanism 300 can be smaller, thus utilizing the miniaturization of the stabilization drive mechanism 300.

[0074] In one embodiment, the number of stabilization coils 321 and auxiliary magnets 313 are the same and correspond one-to-one. The projection of the stabilization coil 321 along the first direction X onto the feature plane is the first projection, and the projection of the first main magnet 311 adjacent to the auxiliary magnet 313 corresponding to the stabilization coil 321 along the first direction X onto the feature plane is the second projection. The first projection and the second projection at least partially overlap. It should be noted that the feature plane is a plane perpendicular to the first direction X. In this embodiment, the feature plane is a virtual plane created to describe the projection and is not a real plane. Figure 9 As can be seen, one end of the anti-shake coil 321 and one end of the first main magnet 311 have a portion that overlaps in the projection of the first direction X.

[0075] By setting the first projection and the second projection to at least partially overlap, the size of the anti-shake coil 321 can be larger, allowing for a larger current through the anti-shake coil 321, thereby increasing the driving force generated by the anti-shake drive mechanism 300. Furthermore, the magnetic field lines generated by the adjacent first main magnet 311 and second main magnet 312 move in the direction of originating from one end of either the first main magnet 311 or the second main magnet 312, crossing the auxiliary magnet 313 between them, and returning to the other end of either the first main magnet 311 or the second main magnet 312. That is, the magnetic flux density at the end of the first main magnet 311 near the auxiliary magnet 313 and the end of the second main magnet 312 near the auxiliary magnet 313 are both very high. Since at least a portion of the anti-shake coil 321 can be aligned with the end of the first main magnet 311 near the auxiliary magnet 313, the magnetic flux density passing through the anti-shake coil 321 is relatively high. According to the Lorentz force calculation formula, this allows for a larger driving force to be generated between the anti-shake coil 321 and the magnet assembly 310.

[0076] Optionally, the projection of the image stabilization coil 321 along the first direction X onto the feature plane is the first projection, and the projection of the second main magnet 312 adjacent to the auxiliary magnet 313 corresponding to the image stabilization coil 321 along the first direction X onto the feature plane is the third projection, and the first projection and the third projection at least partially overlap.

[0077] Similar to the first main magnet 311, by setting the first projection and the third projection to at least partially overlap, the size of the anti-shake coil 321 can be larger, allowing for a larger current through the anti-shake coil 321, thereby increasing the driving force generated by the anti-shake drive mechanism 300. Furthermore, the magnetic field lines generated by the adjacent first main magnet 311 and second main magnet 312 move in the direction of originating from one end of either the first main magnet 311 or the second main magnet 312, crossing the secondary magnet 313 between them, and returning to the other end of either the first main magnet 311 or the second main magnet 312. That is, the magnetic flux density at the end of the first main magnet 311 near the secondary magnet 313 and the end of the second main magnet 312 near the secondary magnet 313 are both very high. Since at least a portion of the anti-shake coil 321 can be aligned with the end of the second main magnet 312 near the secondary magnet 313, the magnetic flux density passing through the anti-shake coil 321 is relatively large. According to the Lorentz force calculation formula, this allows for a larger driving force to be generated between the anti-shake coil 321 and the magnet assembly 310.

[0078] For example, one end of the image stabilization coil 321 is opposite to the first main magnet 311 in the first direction X, and the other end is opposite to the second main magnet 312 in the first direction X, so that a greater driving force can be generated between the image stabilization coil 321 and the magnet assembly 310.

[0079] In one possible implementation, the projection of the image stabilization coil 321 along the first direction X onto the feature plane is the first projection, and the projection of the auxiliary magnet 313 corresponding to the image stabilization coil 321 along the first direction X onto the feature plane is the fourth projection, and the first projection and the fourth projection at least partially overlap.

[0080] By setting the first projection and the corresponding fourth projection to at least partially overlap, the stabilization coil 321 can be located on one side of the auxiliary magnet 313 and directly opposite the auxiliary magnet 313 in the first direction X, thus making full use of the space on one side of the auxiliary magnet 313. Furthermore, the magnetic field lines generated by the adjacent first main magnet 311 and second main magnet 312 move from one of the first main magnet 311 and the second main magnet 312, cross the auxiliary magnet 313 between them, and return to the other of the first main magnet 311 and the second main magnet 312. The stabilization coil 321 is configured with a magnetic field enhancement side cut opposite to the auxiliary magnet 313, allowing more magnetic field lines to pass through the stabilization coil 321, thereby increasing the interaction force between the stabilization coil 321 and the magnet assembly 310, enabling the stabilization drive mechanism 300 to have a larger driving force.

[0081] Optionally, such as Figure 7 As shown, the surface of the image stabilization coil 321 facing the center of the coil assembly 320 is a concave avoidance surface 3211. The avoidance surface 3211 can be used to avoid the camera 200, so that the size of the image stabilization coil 321 can be larger without affecting the installation position of the camera 200.

[0082] In some alternative embodiments, such as Figure 9 As shown, the coil assembly 320 includes four image stabilization coils 321. The four image stabilization coils 321 are a first image stabilization coil 322 and a second image stabilization coil 323 arranged opposite each other in the second direction Y, and a third image stabilization coil 324 and a fourth image stabilization coil 325 arranged opposite each other in the third direction Z. The first image stabilization coil 322, the fourth image stabilization coil 325, the second image stabilization coil 323, and the third image stabilization coil 324... Figure 9 The directions shown are set sequentially at intervals in a clockwise direction.

[0083] When the first stabilization coil 322 and the second stabilization coil 323 are energized, and the third stabilization coil 324 and the fourth stabilization coil 325 are not energized, the coil assembly 320 and the magnet assembly 310 move relative to each other in the third direction Z. That is, the coil assembly 320 and the magnet assembly 310 cooperate to generate a driving force in the third direction Z. By setting two stabilization coils, the magnitude of the driving force generated in the third direction Z can be increased, and higher reliability can be achieved.

[0084] When the third stabilization coil 324 and the fourth stabilization coil 325 are energized, and the first stabilization coil 322 and the second stabilization coil 323 are not energized, the coil assembly 320 and the magnet assembly 310 move relative to each other in the second direction Y. That is, the coil assembly 320 and the magnet assembly 310 cooperate to generate a driving force along the second direction Y. By providing two stabilization coils, the third stabilization coil 324 and the fourth stabilization coil 325, the magnitude of the driving force generated in the second direction Y can be increased, and higher reliability can be achieved.

[0085] In this embodiment, by setting the first anti-shake coil 322, the second anti-shake coil 323, the third anti-shake coil 324 and the fourth anti-shake coil 325, driving forces in the positive and negative directions of the second direction Y and the positive and negative directions of the third direction Z can be provided, so that the anti-shake drive mechanism 300 can realize the anti-shake of the camera module.

[0086] In some optional embodiments, the coil assembly 320 includes a plurality of anti-shake coils 321. When the plurality of anti-shake coils 321 are simultaneously energized, the coil assembly 320 and the magnet assembly 310 rotate relative to each other; that is, one of the coil assembly 320 and the magnet assembly 310 rotates about an axis in a first direction X. When the plurality of anti-shake coils 321 are simultaneously energized, since the plurality of anti-shake coils 321 are spaced apart along a first circumferential direction, the positional interaction of the plurality of anti-shake coils 321 can generate torque, thereby generating a driving force for rotation.

[0087] It should be noted that the rotation of the coil assembly 320 and the magnet assembly 310 can be understood as one of the two rotating while the other remains stationary. The axis of rotation passes through the center of either the coil assembly 320 or the magnet assembly 310 to prevent displacement in the second direction Y and the third direction Z during rotation.

[0088] For example, when the coil assembly 320 includes a first anti-shake coil 322, a second anti-shake coil 323, a third anti-shake coil 324, and a fourth anti-shake coil 325, the first anti-shake coil 322, the second anti-shake coil 323, the third anti-shake coil 324, and the fourth anti-shake coil 325 are simultaneously energized, which can generate a driving force for rotation.

[0089] Corresponding to coil assembly 320, such as Figure 10 As shown, the magnet assembly 310 may include two first main magnets 311, two second main magnets 312, and four auxiliary magnets 313. The arrangement of the two first main magnets 311, the two second main magnets 312, and the four auxiliary magnets 313 is as follows: Figure 7As shown. The first main magnet 311 is an N magnet, and the second main magnet 312 is an S magnet. The magnetic field lines emitted by the first main magnet 311 cross the secondary magnet 313 and return to the second main magnet 312. Figure 10 The thick black arrows indicate the magnetization direction of each of the above magnets.

[0090] Optionally, this embodiment provides a method for controlling the energization of the coil assembly 320, in conjunction with... Figure 10 The magnet assembly 310 shown is detailed in Table 1. In the table, +X represents the positive direction of the second direction Y, and -X represents the negative direction of the second direction Y; +Y represents the positive direction of the third direction Z, and -Y represents the positive direction of the third direction Z; +Z represents counter-clockwise rotation, and -Z represents counter-clockwise rotation. The "+" and "-" signs corresponding to the anti-shake coil 321 indicate opposite current directions. For example, in... Figure 9 In the text, "+" indicates that the current direction in the image stabilization coil 321 is clockwise, "-" indicates that the current direction in the image stabilization coil 321 is counterclockwise, and "NA" indicates that the image stabilization coil 321 is not energized.

[0093] As can be seen from Table 1, when the current direction in the first anti-shake coil 322 and the fourth anti-shake coil 325 is... Figure 9 The clockwise direction shown in the diagram indicates that the current direction in the second anti-shake coil 323 and the third anti-shake coil 324 is [clockwise direction].

Figure 9 When rotating clockwise in the indicated direction, it can produce... Figure 9 The driving force for clockwise rotation in the indicated orientation.

[0094] In some alternative embodiments, such as Figure 10 As shown, the secondary magnet 313 is in contact with the adjacent first main magnet 311, so that within a limited space, the sizes of both the secondary magnet 313 and the first main magnet 311 can be relatively large, or, with fixed sizes, the combined space occupied by the two can be relatively small. For example, the secondary magnet 313 and the adjacent first main magnet 311 can be fixedly connected or tightly abutted, and this embodiment does not limit this. When the secondary magnet 313 and the first main magnet 311 are fixedly connected, the overall integrity of the magnet assembly 310 can be improved.

[0095] Similarly, the secondary magnet 313 is in contact with the adjacent second main magnet 312, so that within a limited space, the sizes of both the secondary magnet 313 and the second main magnet 312 can be relatively large, or, with fixed sizes, the combined space occupied by the two can be relatively small. For example, the secondary magnet 313 and the adjacent second main magnet 312 can be fixedly connected or tightly abutted, and this embodiment does not limit this. When the secondary magnet 313 and the second main magnet 312 are fixedly connected, the overall integrity of the magnet assembly 310 can be improved.

[0096] In some alternative embodiments, such as Figure 10 As shown, the magnet assembly 310 is annular, and its outer contour is polygonal. This makes the magnet assembly 310 regular and facilitates its positioning and assembly in electronic devices. It is understood that the outer contour of the magnet assembly 310 can also be circular, elliptical, etc., and this embodiment does not limit this. In this embodiment, both the outer and inner contours of the magnet assembly 310 are octagonal.

[0097] In one embodiment, such as Figure 10 As shown, the magnet assembly 310 is annular, and its inner contour is polygonal. This makes the magnet assembly 310 regular and facilitates its positioning and assembly in electronic devices. Of course, it is understood that the inner contour of the magnet assembly 310 can also be circular, elliptical, etc., and this embodiment does not limit it to this.

[0098] Optionally, such as Figure 11 As shown, the first main magnet 311 has a first end face 3111 and a second end face 3112 arranged at an angle, and the auxiliary magnet 313 adjacent to the first main magnet 311 has a third end face 3131 and a first side face 412. The first end face 3111 and the third end face 3131 are parallel and in contact, and the second end face 3112 and the first side face 412 are coplanar. Thus, on the one hand, the first main magnet 311 and the auxiliary magnet 313 have a large contact area, improving the reliability of their connection; on the other hand, the coplanarity of the second end face 3112 and the first side face 412 makes the connection position of the first main magnet 311 and the auxiliary magnet 313 more neat, resulting in fewer sharp edges in the magnet assembly 310, and thus a neater overall outline of the magnet assembly 310, facilitating assembly in electronic devices.

[0099] In some alternative embodiments, please continue to refer to Figure 11The second main magnet 312 has a fourth end face 3121 and a fifth end face 3122 arranged at an angle. The auxiliary magnet 313 adjacent to the second main magnet 312 has a sixth end face 3133 and a first side face 412. The fourth end face 3121 and the sixth end face 3133 are parallel and in contact, and the fifth end face 3122 and the first side face 412 are coplanar. In this way, on the one hand, the second main magnet 312 and the auxiliary magnet 313 have a large contact area, which improves the reliability of their connection; on the other hand, the coplanarity of the fifth end face 3122 and the first side face 412 makes the connection position of the second main magnet 312 and the auxiliary magnet 313 more neat, resulting in fewer sharp edges in the magnet assembly 310, and thus making the overall outline of the magnet assembly 310 more neat, which is convenient for assembly in electronic devices.

[0100] In one possible implementation, such as Figure 10 As shown, the length of the first main magnet 311 in the first ring direction is greater than the length of the secondary magnet 313 in the first ring direction. This makes the first main magnet 311 larger, so as to generate sufficient magnetic field lines.

[0101] Optionally, such as Figure 10 As shown, the length of the second main magnet 312 in the circumferential direction of the Hellbeck array is greater than the length of the secondary magnet 313 in the circumferential direction of the Hellbeck array. This arrangement makes the second main magnet 312 larger, so as to generate sufficient magnetic field lines.

[0102] For example, please continue to see Figure 10 The length of the first main magnet 311 in the upward direction of the first ring is equal to the length of the second main magnet 312 in the upward direction of the first ring. This arrangement facilitates the mutual induction between the first main magnet 311 and the second main magnet 312.

[0103] In one embodiment, such as Figure 2As shown, the camera module also includes a support structure 400 suspended within the housing 100. It should be noted that "support structure 400 suspended within housing 100" means that the support structure 400 does not directly contact the inner wall of housing 100, and the support structure 400 is movable relative to housing 100. The camera 200 is mounted on the support structure 400, and at least a portion of the camera 200 extends out of housing 100. That is, a lens hole 110 is provided on one wall of housing 100, and the camera 200 extends out of housing 100 after passing through the lens hole 110, ensuring that housing 100 does not obstruct the wide-angle view of camera 200. In this embodiment, the image stabilization drive mechanism 300 is located within housing 100, the magnet assembly 310 is located on the support structure 400, and the coil assembly 320 is connected to housing 100. Since the housing 100 is usually fixedly installed in electronic devices, when the coil assembly 320 is energized, the magnet assembly 310 and the support structure 400 move relative to the housing 100, thereby causing the camera 200 to move relative to the housing 100, achieving the purpose of image stabilization for the camera 200.

[0104] For example, such as Figure 2 As shown, the housing 100 includes a lower housing 140 and an upper housing 130. The lower housing 140 is fixedly connected to the upper housing 130 to form an accommodating space, and the camera 200 extends out from one wall of the upper housing 130.

[0105] Optionally, the magnet assembly 310 can be fixedly connected to the support structure 400 by means of adhesive, snap-fit, or other methods. The coil assembly 320 can also be directly bonded or indirectly connected to the inner wall of the housing 100 through other structures.

[0106] For example, this embodiment provides a support structure 400, such as Figure 3 As shown, the support structure 400 includes a support body and a plurality of limiting structures 430 disposed on one side of the support body. The plurality of limiting structures 430 are spaced apart along a first circumferential direction, which is the same as the circumferential direction of the support body. The plurality of limiting structures 430 cooperate with the support body to form a limiting space for mounting the magnet assembly 310. At least a portion of the magnet assembly 310 is located in the limiting space and connected to the limiting structures 430, thereby fixing the magnet assembly 310 on the support structure 400.

[0107] By setting multiple limiting structures 430, the material consumption of the support structure 400 can be reduced while ensuring the fixed magnet assembly 310, thus reducing the cost of the support structure 400. In addition, the weight of the support structure 400 can be lighter, which is beneficial to the lightweighting of the support structure 400 and the camera module.

[0108] For example, such as Figure 3As shown, the limiting structure 430 is a protrusion disposed on the support body, and the magnet assembly 310 can be bonded to the support body and the protrusion with adhesive. It should be noted that the height of the limiting structure 430 can be greater than, less than or equal to the thickness of the magnet assembly 310, and this embodiment does not limit this.

[0109] In some optional embodiments, the support structure 400 is a one-piece structure to improve the integrity of the support structure 400 and facilitate its assembly.

[0110] For ease of description, in this embodiment, the length direction of the housing 100 can be defined as the second direction Y, the width direction of the housing 100 as the third direction Z, and the thickness direction of the housing 100 as the first direction X. The length and width of the housing 100 can be the same, in which case the housing 100 is square. Typically, the length of the housing 100 is greater than its width. In this embodiment, the lens hole 110 is formed on one of the housing walls in the thickness direction of the housing 100.

[0111] Optionally, please continue to see Figure 4 and Figure 5 The coil assembly 320 is connected to the first shell wall 120 of the housing 100 (e.g., Figure 2 As shown), the limiting structure 430 has a first groove 431 on the surface facing the first shell wall 120, such as... Figure 5 As shown, the camera module also includes a first rolling element 800 that is rotatably placed in the first groove 431 and in contact with the first shell wall 120.

[0112] By rotatably positioning the first rolling element 800 between the limiting structure 430 and the first housing wall 120, when the camera 200 moves relative to the first housing wall 120 in a direction perpendicular to the first direction X, the first rolling element 800 rotates within the first groove 431. This limits the distance between the limiting structure 430 and the first housing wall 120 in the first direction X, resulting in rolling friction between the support structure 400 and the housing 100. This reduces the resistance during the movement of the support structure 400, thereby reducing the required driving force and lowering the energy consumption of the camera module. Furthermore, the placement of the first rolling element 800 limits the minimum distance between the coil assembly 320 and the magnet assembly 310, preventing them from coming into contact and causing the support structure 400 to become immobile, thus ensuring high reliability.

[0113] Optionally, each limiting structure 430 may be provided with a first rolling element 800 between itself and the first shell wall 120, or a portion of the limiting structures 430 may be provided with a first rolling element 800 between itself and the first shell wall 120. This embodiment does not limit this.

[0114] For example, the first rolling element 800 includes, but is not limited to, balls such as rollers. Alternatively, as... Figure 3 As shown, the first groove 431 is a triangular pyramidal groove to prevent the first rolling member 800 from rolling out of the first groove 431. Furthermore, the triangular pyramidal groove requires less space and can be set on the smaller limiting structure 430.

[0115] In some optional embodiments, the support structure 400 has a limiting groove 440 on its surface facing the first shell wall 120, and at least a portion of the magnet assembly 310 is placed in the limiting groove 440. By providing the limiting groove 440, the support structure 400 can be positioned more precisely, thereby facilitating the assembly of the magnet assembly 310 on the support structure 400. Furthermore, by providing the limiting groove 440, the magnets in the magnet assembly 310 that are not in direct contact with the limiting structure 430 (the first main magnet 311, the secondary magnet 313, or the second main magnet 312) can be limited by the limiting groove 440, preventing the magnets from moving.

[0116] Optionally, such as Figure 3 As shown, the limiting groove 440 is a shallow groove provided on the support body of the support structure 400, and a part of the magnet assembly 310 is located in the limiting groove 440.

[0117] In some alternative embodiments, please continue to refer to Figure 3 The support structure 400 can be provided with either a limit structure 430 or a limit groove 440. Of course, it is understandable that the support structure 400 can also be provided with only the limit structure 430, or the support structure 400 can be provided with only the limit groove 440.

[0118] To improve the fixing effect of the camera 200, for example, such as Figure 3 As shown, the support structure 400 is provided with an extension 410. The extension 410 extends toward the first shell wall 120. The extension 410 is provided with a mounting hole 411, into which the camera 200 is mounted. By providing the extension 410, the connection area between the support structure 400 and the camera 200 can be increased, reducing the risk of the camera 200 tilting and improving the connection strength between the camera 200 and the support structure 400. In this embodiment, the extension 410 is provided on the bracket body.

[0119] Optionally, such as Figure 4As shown, the magnet assembly 310 is sleeved on the outer periphery of the extension 410, and the surface of the extension 410 facing the magnet assembly 310 is inclined. The magnet assembly 310 is disposed on the outer periphery of the extension 410, allowing the extension 410 to both fix the camera 200 and limit the movement of the magnet assembly 310, thus enriching the functionality of the extension 410. The inclined surface facilitates the guidance of the magnet assembly 310 when it is assembled onto the support structure 400, thereby simplifying its installation. It should be noted that the inclined direction of the inclined surface is such that the end of the inclined surface closest to the first shell wall 120 is inclined towards the camera 200.

[0120] Optionally, such as Figure 3 As shown, the extension 410 includes a first side surface 412 opposite to the first main magnet 311, a second side surface 413 opposite to the second main magnet 312, and a third side surface 414 opposite to the auxiliary magnet 313. The first side surface 412 is planar to better fit the shape of the first main magnet 311 and guides the first main magnet 311 during assembly. The second side surface 413 is planar to better fit the shape of the second main magnet 312 and guides the second main magnet 312 during assembly. The third side surface 414 is planar to better fit the shape of the auxiliary magnet 313 and guides the auxiliary magnet 313 during assembly.

[0121] The camera module in this embodiment also has a focus adjustment function. For example, as shown... Figure 2 As shown, the camera module also includes a focusing mechanism 500. The focusing mechanism 500 is suspended within the housing 100, specifically meaning that it does not directly contact the inner wall of the housing 100. The focusing mechanism 500 is used to drive the camera 200 to move in the focusing direction to adjust the focal length between the camera 200 and the object. The focusing direction is the same as the axial direction of the camera 200, that is, the focusing direction is the first direction X.

[0122] Optionally, please continue to see Figure 4 The focusing mechanism 500 includes a focusing magnet 510, a focusing coil 520, and a focusing connector 530. One of the focusing magnet 510 and the focusing coil 520 is connected to the housing 100, and the other is connected to the focusing connector 530. The focusing connector 530 is connected to the support structure 400, for example, it is fixedly connected to the support structure 400. The focusing magnet 510 and the focusing coil 520 cooperate to drive the focusing connector 530 to move relative to the housing 100 in the focusing direction, thereby causing the camera 200 to move relative to the housing 100 in the focusing direction, achieving focal length adjustment. When the focusing coil 520 is energized, it interacts with the focusing magnet 510 to generate a driving force in the focusing direction.

[0123] By setting the focusing mechanism 500, the camera 200 can be driven to move in the first direction X. By setting the image stabilization driving mechanism 300, the camera 200 can move in the second direction Y and the third direction Z. It can also rotate around the axis in the first direction X, giving the camera 200 multiple degrees of freedom, making the camera 200 more flexible and improving the image quality.

[0124] In some alternative embodiments, such as Figure 5 As shown, the focusing connector 530 includes a first connecting portion 531 and a second connecting portion 532 that are vertically connected. The first connecting portion 531 is located on the side of the support structure 400 facing away from the first shell wall 120 of the housing 100 and is connected to the support structure 400. A focusing coil 520 or a focusing magnet 510 is connected to the second connecting portion 532. In this embodiment, the second connecting portion 532 is disposed opposite to the side wall of the housing 100; that is, the focusing coil 520 and the focusing magnet 510 are located on one side of the camera 200. This makes the distribution of components within the housing 100 more rational, fully utilizes the internal space of the housing 100, and facilitates the thinning and miniaturization of the camera module.

[0125] Optionally, both the first connecting part 531 and the second connecting part 532 can be plate bodies, and this embodiment does not limit this. In this embodiment, the focusing magnet 510 is fixedly connected to the second connecting part 532, and the focusing coil 520 is fixedly connected to the side wall of the housing 100.

[0126] Optionally, an internal support member 700 is provided inside the housing 100, such as... Figure 12 As shown, the inner support member 700 includes a support plate 710 and a first column 720 and a second column 730 disposed on the support plate 710. The support plate 710 is fixedly connected to the first shell wall 120. The first column 720 and the second column 730 are located on the side of the support plate 710 facing away from the first shell wall 120 and extend along the thickness direction of the shell 100. The coil assembly 320 is fixedly connected to the support plate 710, thereby indirectly fixedly connected to the shell 100 through the support plate 710. The support plate 710 has a hole (not shown) for the camera 200 to pass through, and this hole is coaxially arranged with the camera 200 hole.

[0127] To reduce the frictional force when the focusing connector 530 moves relative to the housing 100, in this embodiment, as follows: Figure 5 As shown, a second rolling element 900 is provided between the second connecting portion 532 of the focusing connector 530 and the first column 720. Specifically, as... Figure 13 As shown, the second connecting part 532 is provided with a first V-shaped groove 5321 facing the first column 720, such as Figure 12As shown, the first column 720 is provided with a second V-groove 721 facing the second connecting portion 532. The second rolling element 900 is rotatably disposed between the first V-groove 5321 and the second V-groove 721 to limit its movement through the first V-groove 5321 and the second V-groove 721. By providing the second rolling element 900, the frictional force when the focusing connecting member 530 moves relative to the housing 100 can be reduced, thereby achieving the purpose of reducing the energy consumption of the camera module.

[0128] In some alternative embodiments, the camera module also includes a circuit board assembly 600 connected to the housing 100, and each image stabilization coil and focus coil 520 of the coil assembly 320 are electrically connected to the circuit board assembly 600.

[0129] For example, such as Figure 2 As shown, the circuit board assembly 600 includes a first circuit board 610 and a second circuit board 620 electrically connected.

[0130] In some optional embodiments, multiple image stabilization coils 321 are fixedly connected to the first circuit board 610, and the focusing coil 520 is also fixedly connected to the second circuit board 620, so that the first circuit board 610, the second circuit board 620, the focusing coil 520 and the image stabilization coil 321 are connected into an integrated structure, which reduces the number of components in the camera module and facilitates the assembly and disassembly of the camera module.

[0131] This embodiment also provides an electronic device, which includes the above-described image stabilization drive mechanism; or, the electronic device includes the above-described camera module.

[0132] When the electronic device provided in this embodiment includes an image stabilization drive mechanism, it can reduce mutual interference between image stabilization drive mechanisms and has high reliability. When the electronic device includes a camera module, the imaging effect is better.

[0133] It should be noted that when the camera module includes a housing, the housing may be part of the device housing of the electronic device, or the housing may be fixedly connected to the device housing of the electronic device.
