Description

Technical Field

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

[0002] With the development of technology, the shooting functions of mobile phones and other electronic devices have become increasingly powerful. The shooting function of electronic devices is an important factor affecting the user experience. Optical image stabilization is an important function to improve the shooting quality. Optical image stabilization refers to the use of optical components, such as lens settings, in cameras or other similar imaging instruments to avoid or reduce the instrument shake that occurs during the capture of optical signals, thereby improving image quality.

[0003] In existing technologies, image stabilization is generally achieved through a stabilization motor. A stabilization motor typically consists of a movable carrier and a fixed, immovable component, which are usually "softly" connected by a suspension wire. When the carrier moves relative to the fixed component, the fixed component supports the carrier, preventing the carrier from detaching from the fixed component and allowing it to move near it, or the carrier is supported on the fixed component.

[0004] However, the suspension wire fixing method may cause the carrier to sway or deflect relative to the base, resulting in poor anti-shake performance of the anti-shake motor. Summary of the Invention

[0005] The purpose of this application is to provide a stabilization motor, a camera module, and an electronic device.

[0006] In a first aspect, embodiments of this application provide a stabilization motor, including a base, a carrier, a connecting component, and a first magnetic component. The base has a receiving space; the carrier is located in the receiving space and has an optical space for mounting an optical lens, and the carrier has a centerline passing through the optical space; the connecting component connects the base and the carrier, enabling the carrier to rotate relative to the base around the centerline of the carrier; the first magnetic component is arranged around the optical space, and the first magnetic component includes a first magnetic element and a second magnetic element. The first magnetic element is fixed to the base, and the second magnetic element is fixed to the carrier. The first magnetic element and the second magnetic element attract each other, causing the carrier to be held against the base by the connecting component.

[0007] In this embodiment, by setting a connecting component, the carrier can rotate relative to the base. The connecting component can support the carrier in the circumferential direction of the base and can also support the carrier in the axial direction of the base, so that the carrier maintains a stable relative position with respect to the base.

[0008] The carrier can float relative to the base due to the attraction of the first magnetic component, forming a soft connection between the carrier and the base, and generating pre-pressure between them. Furthermore, by rationally positioning the first magnetic component, it reuses the height space of the optical space along the extension direction of the centerline. In the image stabilization motor, there is no need to provide additional space for the first magnetic component, which helps to reduce the height of the image stabilization motor and facilitates its thinner design.

[0009] In some embodiments, there are multiple first magnetic elements and multiple second magnetic elements. One first magnetic element and one second magnetic element face each other and form a magnetic attraction structure. Multiple magnetic attraction structures are arranged at intervals around the optical space.

[0010] For example, multiple sets of magnetic structures can be evenly spaced.

[0011] For example, multiple sets of magnetic structures can be arranged around the center line of the optical space.

[0012] In this embodiment, multiple sets of magnetic attraction can generate pre-pressure to connect the carrier to the base. Multiple sets of magnetic attraction structures form multiple forces between the base and the carrier. Multiple sets of magnetic attraction structures can cooperate with each other to position the base on the carrier in multiple directions and keep the relative position of the base and the carrier stable in multiple directions. When the position of the carrier deviates from the base, the multiple sets of magnetic attraction structures have a tendency to make the carrier automatically return to the center.

[0013] In some embodiments, the magnetic attraction directions of the first and second magnetic elements of the multiple magnetic attraction structures intersect with the center line of the carrier, and the resultant force direction of the multiple magnetic attraction structures is parallel to the center line of the carrier and faces the light entrance of the optical space.

[0014] For example, the resultant force direction of multiple magnetic attraction structures coincides with the centerline of the carrier.

[0015] In this embodiment, the multiple sets of magnetic attraction structures apply forces to the base and the carrier in the same direction, making the forces on the base and the carrier more uniform and simple, which is beneficial for controlling the direction of the resultant force on the carrier.

[0016] In some embodiments, the first magnetic element has a first surface and the second magnetic element has a second surface. The first surface and the second surface are disposed opposite to each other. The first surface is curved and concave away from the second surface, and the second surface is curved and convex toward the first surface.

[0017] For example, the first and second surfaces can each be spheres, and the centers of the first and second surfaces can coincide.

[0018] In this embodiment, the distance between the first magnetic component and the second magnetic component remains constant and will not change due to the relative rotation of the carrier and the base, nor will it collide with the carrier due to the relative rotation of the carrier and the base. This is beneficial for reducing the distance between the first magnetic component and the second magnetic component, thereby saving space. Furthermore, it is also beneficial for the carrier to move in multiple directions and at large angles relative to the base.

[0019] In some embodiments, in multiple sets of magnetic attraction structures, the first and second magnetic elements of each set of magnetic attraction structures are arranged in the direction of rotation of the base and the carrier.

[0020] In this embodiment, the resultant force point of the first magnetic attraction component coincides with the rotation center point of the base and the carrier. When the carrier moves relative to the base, the carrier is not easily deflected or deviated from the base, which is conducive to the carrier moving in a more accurate manner and facilitates the motion control of the carrier.

[0021] In some embodiments, one of the first magnetic element and the second magnetic element includes a magnetic absorbing sheet that is not magnetic and is made of a ferromagnetic material, and the other of the first magnetic element and the second magnetic element includes a magnet that is magnetic.

[0022] For example, the first magnetic element may include a magnetic chuck, and the second magnetic element may include a magnet.

[0023] For example, a magnet can be a single magnet block; or, a magnet can be multiple magnet blocks, such as a Heilbeck magnet array.

[0024] In this embodiment, the magnetic absorbing sheet is easy to manufacture, its shape is easy to control, and it is easy to manufacture a thinner magnetic absorbing sheet, which is beneficial to reducing the space occupied by the first magnetic component and the second magnetic component, and is beneficial to the miniaturization design of the anti-shake motor.

[0025] In some embodiments, the magnetic absorbing sheet may have a first through hole located in the middle of the magnetic absorbing sheet.

[0026] In this embodiment, the magnetic absorbing sheet forms a ring structure. When the magnetic absorbing sheet is attracted, it can form a ring magnetic circuit. During the relative movement between the magnetic absorbing sheet and the magnet, the magnetic absorbing sheet has a better return-to-center ability, which is beneficial to keeping the position of the carrier relative to the base stable.

[0027] In some implementations, the magnetic chuck may not have a first through hole, which helps to create a stronger attraction between the magnetic chuck and the magnet.

[0028] In some embodiments, the width of the magnet is greater than the width of the magnetic chuck; and / or, the height of the magnetic chuck is greater than the height of the magnet; wherein the width direction of the magnetic chuck is parallel to the width direction of the corresponding magnet; the height direction of the magnetic chuck is parallel to the height direction of the corresponding magnet, and the width direction of the magnetic chuck is perpendicular to the height direction of the magnetic chuck.

[0029] In this embodiment, when the magnet and the magnetic chuck move relative to each other in the length direction (e.g., rotate), the magnet's longer length and stronger magnetism facilitate the magnetic chuck's return to its centered position after moving relative to the magnet, thus facilitating the centering of the carrier relative to the base after movement. Furthermore, when the magnet and the magnetic chuck move relative to each other in the height direction (e.g., rotate), the magnetic chuck's greater height and stronger magnetic attraction between the magnetic chuck and the magnet facilitate the magnetic chuck's return to its centered position after moving relative to the magnet, thus facilitating the centering of the carrier relative to the base after movement.

[0030] In some implementations, when the width of the magnet is greater than the width of the magnetic chuck, the ratio of the width of the magnet to the width of the magnetic chuck is greater than or equal to 1.5.

[0031] In this embodiment, by optimizing the width ratio of the magnet and the magnetic absorbing sheet, the magnet and the magnetic absorbing sheet are made to have suitable magnetic attraction force and centering ability.

[0032] In some implementations, when the height of the magnetic accumulator is greater than the height of the magnet, the ratio of the height of the magnetic accumulator to the height of the magnet is greater than or equal to 1.5.

[0033] In this embodiment, by optimizing the height ratio of the magnet and the magnetic absorbing plate, the magnet and the magnetic absorbing plate are made to have suitable magnetic attraction force and centering ability.

[0034] In some embodiments, the first magnetic component further includes a shield that covers the side of the magnet away from the magnetic absorbing sheet.

[0035] For example, the first magnetic element includes a magnetic absorbing sheet, and the second magnetic element includes a magnet. A shielding cover is disposed on the side of the second magnetic element opposite to the first magnetic element.

[0036] In this embodiment, the anti-shake motor generally contains other components that have magnetic fields or utilize magnetic fields. The magnet of the first magnetic component is magnetic, and a shield is provided on the side facing away from the magnetic absorbing sheet to prevent the magnetism of the magnet from affecting other magnetic fields on the side of the magnet facing away from the magnetic absorbing sheet, thereby improving the reliability of the anti-shake motor.

[0037] In some embodiments, the carrier and the base are connected by a connecting component ball, and the carrier and the base are rotatable about a first direction, a second direction and a third direction. The first direction is parallel to the centerline of the carrier, and the second and third directions are perpendicular to the first direction and different from the third direction.

[0038] In this embodiment, the carrier can rotate relative to the base in at least three directions. When multiple rotational movements are combined, the carrier can rotate omnidirectionally relative to the base. The carrier has a high degree of freedom, which improves the anti-shake capability of the anti-shake motor.

[0039] In some embodiments, the connecting assembly includes a plurality of ball bearings that are rotatably connected between the base and the carrier; the number of first magnetic elements is plurality of, with at least one ball bearing located between two first magnetic elements.

[0040] For example, the first magnetic element and the ball element are arranged alternately around the optical space.

[0041] In this embodiment, the connection points between the carrier and the base and the points where the connecting force is applied are arranged alternately along the circumference of the carrier, making the force on the carrier more balanced and the movement of the carrier relative to the base more stable.

[0042] In some embodiments, the base includes a first wall, the carrier includes a second wall, and the connecting component abuts against the first wall and the second wall, wherein the first wall and / or the second wall are both spherical.

[0043] In this embodiment, the distance between the first and second walls remains constant during relative movement, resulting in more accurate and stable movement of the carrier relative to the base. When there are multiple ball grooves and multiple second walls, i.e., the anti-shake motor includes multiple rolling connection structures, the centers of the balls on the multiple first walls can coincide, and also coincide with the centers of the balls on the multiple second walls. This allows the carrier to rotate about the axial direction of the base and about any radial direction of the base. It is understood that the radial direction of the base is perpendicular to its axial direction.

[0044] In some embodiments, the anti-shake motor further includes a second magnetic component, which includes a third magnetic element and a fourth magnetic element. The third magnetic element is fixedly connected to the base, and the fourth magnetic element is fixedly connected to the carrier. The third magnetic element and the fourth magnetic element repel each other.

[0045] For example, the repulsive forces of the third and fourth magnetic elements coincide with the centerline of the carrier.

[0046] In this embodiment, since the third and fourth magnetic components repel each other, the third magnetic component supports the fourth magnetic component, that is, the base supports the carrier, and the base supports the carrier through the connecting assembly. The second magnetic component causes the carrier to press against the base through the connecting assembly. Furthermore, the closer the third and fourth magnetic components are, the greater the repulsive force between them, which is beneficial to improving the vibration and impact resistance of the camera module.

[0047] In some embodiments, the projection of the outline edge of the third magnetic element overlaps the projection of the outline edge of the fourth magnetic element in the direction of the centerline of the carrier.

[0048] In this embodiment, when the carrier rotates relative to the base, the fourth magnetic element moves relative to the third magnetic element. The third magnetic element has a larger area, which allows it to exert a repulsive force on the fourth magnetic element after the fourth magnetic element moves. Furthermore, the larger area of ​​the fourth magnetic element facilitates the centering of the third magnetic element relative to the fourth magnetic element, thereby helping the carrier return to the center position of the base.

[0049] In some embodiments, the ratio of the diameter of the third magnetic element to the diameter of the fourth magnetic element is in the range of 1.5 to 2.

[0050] In this embodiment, by optimizing the ratio of the diameter of the third magnetic component to the diameter of the fourth magnetic component, the third magnetic component is made to have a suitable size relative to the fourth magnetic component, which is beneficial to make the third magnetic component and the fourth magnetic component have a suitable repulsive force and return capability.

[0051] In some embodiments, the surface of the third magnetic element facing the fourth magnetic element is called the third surface, and the surface of the fourth magnetic element facing the third magnetic element is called the fourth surface; wherein, the third surface is a curved surface and is recessed away from the fourth magnetic element; and / or, the fourth surface is a curved surface and is protruding towards the third magnetic element.

[0052] In this embodiment, when the third surface is a concave curved surface, it is beneficial to center the magnetic force direction of the third and fourth magnetic components. Furthermore, it helps to prevent collisions caused by the movement of the fourth magnetic component relative to the third magnetic component, and it also helps to reduce the distance between the third and fourth magnetic components.

[0053] When the fourth surface is curved, the magnetic force of the third magnetic component is more concentrated at the end closest to the fourth magnetic component, which helps to center the magnetic force direction of the third and fourth magnetic components. Furthermore, it helps to prevent collisions caused by the movement of the fourth magnetic component relative to the third magnetic component and helps to reduce the distance between the third and fourth magnetic components.

[0054] In some embodiments, the third magnetic element is a ring structure, and the ratio of the outer diameter to the inner diameter of the third magnetic element is greater than or equal to 1.3.

[0055] In this embodiment, the magnetic field of the third magnetic element is stronger at the ring structure, and the magnetic repulsion between the third and fourth magnetic elements is more easily centered. This is beneficial for maintaining the stability of the repulsion between the fourth and third magnetic elements, and also for the fourth magnetic element to return to center after moving relative to the third magnetic element.

[0056] By optimizing the ratio of the outer diameter to the inner diameter of the third magnetic component, a suitable magnetic repulsion force and centering capability are achieved between the third and fourth magnetic components.

[0057] In some embodiments, the image stabilization motor may further include a focusing motor, which is fixedly connected to the carrier and located in the receiving space; wherein the first magnetic component is located on the side of the focusing motor near the light inlet of the optical space.

[0058] In this embodiment, the distance between the first magnetic component and the position of the first magnetic component is set, which is beneficial for the arrangement of components such as the focusing motor and further improves the space utilization.

[0059] Secondly, embodiments of this application provide a camera module, including an optical lens, a sensor assembly, and a stabilization motor as described in any embodiment of the first aspect, wherein the optical lens and the sensor assembly are fixed to a carrier, and the optical lens is located in an optical space.

[0060] The camera module in this embodiment is easy to design in a thinner form.

[0061] Thirdly, embodiments of this application provide an electronic device, including a device housing and a camera module as provided in the second aspect, wherein the camera module is disposed in the device housing.

[0062] The electronic device in this embodiment is easy to design in a thinner form. Attached Figure Description

[0087] The embodiments of this application are described below with reference to the accompanying drawings.

[0088] In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," "joining," and "joining" should be interpreted broadly. For example, "joining" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be an electrical connection or a mechanical connection. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Movable connection" refers to a connection where the relative positional relationship can change after connection. "Rotary connection" refers to a connection where the relative positional relationship can change. "Sliding connection" refers to a connection where the relative positional relationship can change. Furthermore, the integrated structure obtained by a one-piece molding process means that during the formation of one of the two components, that component is connected to the other component without requiring further processing (such as bonding, welding, snap-fit ​​connections, or screw connections) to connect the two components. Components A and B can be arranged relative to each other such that component A is projected along the target direction to obtain projection C, and component B is projected along the target direction to obtain projection D, with projection C and projection D at least largely overlapping. In some embodiments, the majority overlap can be any of the following: projection C is entirely within projection D; or projection D is entirely within projection C; or projection C and projection D intersect each other, and the intersection area of ​​projection C and projection D accounts for more than 50% of projection C or projection D.

[0089] The directional terms mentioned in the embodiments of this application, such as "top," "bottom," "inner," "outer," "upper," and "lower," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0090] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship. "Multiple" means at least two.

[0091] Furthermore, the limitations on relative positional relationships mentioned in the embodiments of this application, such as parallelism and perpendicularity, are all relative to the current technological level and are not absolutely strict limitations. Slight deviations are allowed; approximations of parallelism or perpendicularity are acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0092] Figure 1 This is a schematic diagram of the structure of an electronic device 1000 provided in an embodiment of this application.

[0093] like Figure 1 As shown, the electronic device 1000 can be a mobile phone, tablet personal computer, laptop computer, personal digital assistant (PDA), camera, personal computer, laptop computer, in-vehicle equipment, wearable device, augmented reality (AR) glasses, AR helmet, virtual reality (VR) glasses, or VR helmet, or other devices with camera functions. Figure 1 The electronic device 1000 of the embodiment shown is illustrated using a mobile phone as an example.

[0094] Figure 2 yes Figure 1 The electronic device 1000 shown is a partial cross-sectional view in one embodiment.

[0095] like Figure 1 and Figure 2 As shown, the electronic device 1000 may include a camera module 100, a device housing 200, and a screen 300. The camera module 100 may be a rear camera module or a front camera module. Figure 2 Camera module 100 is schematically shown using a dashed box. It is understandable that... Figure 1 The accompanying drawings below only schematically illustrate some components included in the electronic device 1000; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 As well as the accompanying drawings below. Furthermore, when the electronic device 1000 is a device of some other form, the electronic device 1000 may not include the screen 300.

[0096] like Figure 1 and Figure 2 As shown, in some embodiments, the screen 300 is mounted on the device housing 200 and together with the device housing 200 encloses the interior of the electronic device 1000. The interior of the electronic device 1000 can be used to house components of the electronic device 1000, such as a battery, receiver, or microphone. The screen 300 can be a flat screen or a curved screen.

[0097] For example, the camera module 100 may be located inside the electronic device 1000. The device housing 200 has a light-transmitting portion 2001. The shape of the light-transmitting portion 2001 is not limited to that of the attached device. Figure 1 The shape shown can be a circle, an ellipse, or an irregular shape. Light from outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting part 2001. The camera module 100 can capture the light entering the interior of the electronic device 1000.

[0098] like Figure 2 As shown, the camera module 100 includes a sensor assembly 10 and an optical lens 20 arranged sequentially from the image side to the object side. The sensor assembly 10 can be used to convert image information carried by ambient light into electrical signals. The camera module 100 can have a length direction, a width direction, and a height direction. The width direction of the camera module 100 is parallel to the X direction, the length direction is parallel to the Y direction, and the height direction is parallel to the Z direction.

[0099] It is understood that the optical lens 20 and the sensor assembly 10 can form an integrated camera module 100. In this way, compared with a camera module 100 in which the optical lens 20 and the sensor assembly 10 are set separately, the camera module 100 in this embodiment is smaller in size, which is conducive to the miniaturization of the camera module 100, thereby saving internal space of the electronic device 1000 and providing a better user experience.

[0100] For example, sensor assembly 10 includes at least a photosensitive element. The photosensitive element utilizes the photoelectric conversion function of an optoelectronic device to convert the light image on the photosensitive surface into an electrical signal that is proportional to the light image. For example, the photosensitive element can be a charge-coupled device (CCD), a complementary metal-oxide-semiconductor (CMOS), etc.

[0101] For example, the optical lens 20 may include at least one lens. The lenses of the optical lens 20 may be grouped into one lens group or multiple lens groups. When the optical lens 20 includes multiple lens groups, at least one lens group can move along the optical axis. For example, as... Figure 2 As shown, the optical lens 20 includes a first lens 201 and a second lens 202.

[0102] Understandably, the camera module 100 may also include a drive motor, which drives the lens group in the optical lens 20 that can move along the optical axis to achieve zoom or focus.

[0103] It is understood that the optical lens 20 may have an incident light side and an exit light side, and at least part of the light rays enter the optical lens 20 from the incident light side, pass through the optical lens 20, and then enter the sensor assembly 10 from the exit light side of the optical lens 20. For example, the light rays may enter the photosensitive element of the sensor assembly 10 along a first direction (i.e., the Z direction).

[0104] like Figure 2As shown, the camera module 100 also includes a stabilization motor 30. The sensor assembly 10 can be mounted on the stabilization motor 30. The stabilization motor 30 can control the sensor assembly 10 to move along a plane perpendicular to the first direction (i.e., the XY plane) and around the first direction to achieve optical image stabilization (OIS). Thus, when the camera module 100 captures ambient light, if the electronic device 100 shakes due to external forces, the stabilization motor 30 can control the sensor assembly 10 to move in the XY plane and around the first direction to counteract the shaking travel of the optical lens 20, thereby reducing the positional offset of the camera module 100 caused by shaking. In other words, the camera module 100 of this application can control the sensor assembly 10 to move in the XYZ space through the stabilization motor 30 to achieve optical image stabilization of the camera module 100, and has strong stabilization capabilities, improving the image quality of the camera module 100, enhancing the shooting function of the electronic device 1000, and providing a good user experience.

[0105] For example, the anti-shake motor 30 can control the sensor assembly 10 to rotate along the X, Y and Z directions.

[0106] It is understood that the above description only illustrates one embodiment of the sensor component 10 applied to the camera module 100. In other embodiments, the sensor component 10 may also be applied to camera modules 100 with other structures. Specifically, this application does not limit the application.

[0107] In this embodiment, the side of the camera module 100 facing away from the screen 300 is designated as the "top", and the side facing the screen 300 is designated as the "bottom".

[0108] Please refer to the following: Figure 3 and Figure 4 , Figure 3 yes Figure 2 The diagram shows the structure of the camera module 100 in some embodiments. Figure 4 yes Figure 3 The image shows an exploded view of the camera module 100 in some embodiments.

[0109] In some embodiments, the image stabilization motor 30 of the camera module 100 may further include a housing assembly 1, a first magnetic assembly 2, a second magnetic assembly 3, and a connecting assembly 4. The housing assembly 1 serves as a support structure for the camera module 100, and the first magnetic assembly 2, the second magnetic assembly 3, and the connecting assembly 4 can all be mounted on the housing assembly 1.

[0110] The housing assembly 1 may include a base 11, a carrier 12, and a bottom shell 13.

[0111] In some embodiments, the image stabilization motor 30 of the camera module 100 may further include a drive magnetic component 5. The drive magnetic component 5 may be mounted on the housing component 1 for image stabilization of the camera module 100.

[0112] In some embodiments, the camera module 100 may further include a focusing motor 40 for mounting the lens of an optical lens to achieve focusing of the optical lens.

[0113] In some embodiments, an optical space 12a may be formed inside the camera module 100, and the optical space 12a is used to mount an optical lens. The camera module 100 may have a light inlet 50 in the optical space 12a, and the light inlet 50 is used to allow light to enter the optical space 12a so as to facilitate imaging by the camera module 100.

[0114] Please see Figure 5A and Figure 5B , Figure 5A yes Figure 4 The diagram shows the structure of the base 11 in some embodiments; Figure 5B yes Figure 5A A structural diagram from another perspective. Among them, Figure 5B The viewpoint shown is Figure 5A The base 11 shown is viewed from the perspective after being flipped.

[0115] In some embodiments, the base 11 may include a top 111 and a side 112, the side 112 of the base 11 surrounding the top 111 of the base 11 and fixedly connected to the top 111 of the base 11. The top 111 and the side 112 of the base 11 may form a receiving space 11a, which may communicate with the external space of the base 11.

[0116] For example, the base 11 may have a first opening 113 and a second opening 114. The first opening 113 may be located at the top 111 of the base 11, and at the middle of the top 111. The second opening 114 may be located at the bottom, at the end of the bottom facing away from the top 111 of the base 11. The first opening 113 and the second opening 114 may be arranged opposite to each other, and both the first opening 113 and the second opening 114 communicate with the receiving space 11a and the external space of the base 11. The base 11 may have an axial direction, which may be parallel to the opening direction of the first opening 113. For example, the arrangement direction of the first opening 113 and the second opening 114 may be parallel to the axial direction of the base 11 and parallel to the Z-direction.

[0117] For example, the first opening 113 can be approximately circular, and the second opening 114 can be approximately rectangular. For example, the area of ​​the first opening 113 can be smaller than the area of ​​the second opening 114.

[0118] For example, the base 11 may have ball grooves 115. The ball grooves 115 may be formed on the top 111 of the base 11 and located on the inner side of the top 111 of the base 11. There may be multiple ball grooves 115, which are spaced apart circumferentially on the base 11. For example, there may be four ball grooves 115.

[0119] The ball groove 115 may include a first wall surface 1151 and a side wall surface 1152, with the side wall surface 1152 connected to and surrounding the first wall surface 1151. For example, the side wall surface 1152 may be an annular curved surface. The first wall surface 1151 may be a sphere. The center of the sphere of the first wall surface 1151 may be located within the receiving space 11a. When there are multiple ball grooves 115, the multiple first walls 1151 may share a common center.

[0120] For example, the base 11 may have a first receiving groove 116. The first receiving groove 116 may be formed on the top 111 of the base 11 and located on the inner side of the top 111 of the base 11. There may be multiple first receiving grooves 116, which are spaced apart circumferentially on the base 11. For example, there may be four first receiving grooves 116.

[0121] The first receiving groove 116 and the ball groove 115 are arranged circumferentially on the base 11. When there are multiple first receiving grooves 116 and multiple ball grooves 115, the multiple first receiving grooves 116 and multiple ball grooves 115 can be arranged alternately.

[0122] For example, the base 11 may also have a second receiving groove 117. The second receiving groove 117 may be formed on the side 112 of the base 11. The second receiving groove 117 may include multiple slots.

[0123] For example, the second receiving slot 117 may include a first slot 1171, a second slot 1172, and a third slot 1173. The first slot 1171, the second slot 1172, and the third slot 1173 may all be approximately rectangular. The first slot 1171 and the third slot 1173 may be arranged opposite to each other, and the second slot 1172 may be located between the first slot 1171 and the second slot 1172. The dimensions of the second slot 1172 may be approximately the same, and the dimensions of the first slot 1171 may be smaller than the dimensions of the second slot 1172 and the third slot 1173.

[0124] Please refer to the following: Figures 5A to 6 , Figure 6 yes Figure 5A The base 11 shown is an exploded structural diagram in some embodiments.

[0125] In some embodiments, the base 11 may include a main housing 1191, an insert 1192, and a support 1193.

[0126] For example, the main housing 1191 can serve as the main component of the base 11, and the first opening 113 can be formed in the main housing 1191. The main housing 1191 can have a first surface 1191a, which can be a curved surface. The first surface 1191a can surround the first opening 113 and be located on the outer side of the main housing 1191 opposite to the first opening 113. For example, the first surface 1191a can be an annular spherical surface. The main housing 1191 can have fixing grooves 1191b. There can be multiple fixing grooves 1191b, which are arranged at intervals around the first surface 1191a.

[0127] For example, the insert 1192 can be an annular member, and the insert 1192 can be used to form a partial structure of the top 111 of the base 11. The insert 1192 can include an annular portion 1192a and a fixing portion 1192b, with the fixing portion 1192b fixedly connected to the annular portion 1192a. There can be multiple fixing portions 1192b, which are spaced apart around the annular portion 1192a. The annular portion 1192a has a second surface 1192c, which can be an annular surface. For example, the first surface 1191a can be an annular spherical surface.

[0128] The insert 1192 can be a one-piece molded structural component. The insert 1192 can be made of metal to improve its wear resistance. In other embodiments, the insert 1192 can also be a separate structural component.

[0129] For example, the support member 1193 can be generally a frame structure. The support member 1193 may include a frame 1193a and a boss 1193b, the boss 1193b being fixedly connected to the frame 1193a. The boss 1193b protrudes relative to the frame 1193a. The boss 1193b is used to fixably connect to the side portion 112 of the base 11 and is located on the side of the base 111 facing the receiving space 11a. The boss 1193b and the top 111 of the base 11 may be spaced apart. There may be multiple bosses 1193b, spaced apart circumferentially along the base 11. For example, there may be four bosses 1193b.

[0130] Please refer to the following: Figure 5A and Figure 6 In some embodiments, the insert 1192 and the support 1193 are respectively fixedly connected to the main housing 1191.

[0131] For example, the insert 1192 may surround the first opening 113 and mate with the main housing 1191. The insert 1192 may be mounted on the top side of the main housing 1191 and form part of the structure of the top 111 of the base 11.

[0132] The fixing portion 1192b of the insert 1192 can be located in the fixing groove 1191b of the main housing 1191. The fixing groove 1191b is filled with adhesive material to bond the fixing portion 1192b, thereby fixing the insert 1192 to the main housing 1191. The second surface 1192c of the insert 1192 abuts against the first surface 1191a of the main housing 1191. The first surface 1191a and the second surface 1192c can fit together to position the insert 1192 on the main housing 1191. A portion of the second surface 1192c can form the first wall surface 1151 of the ball groove 115. When the insert 1192 is made of a wear-resistant material such as metal, the first wall surface 1151 of the ball groove 115 is also a wear-resistant surface. When the first wall surface 1151 of the ball groove 115 rubs against other components, it helps to extend the service life of the ball groove 115.

[0133] For example, the support member 1193 can be installed on the bottom side of the main housing 1191 and is disposed opposite to the insert 1192. The frame 1193a of the support member 1193 is fixedly connected to the bottom end of the main housing 1191 and forms the second opening 114 of the base 11. The boss portion 1193b of the support member 1193 is located inside the main housing 1191.

[0134] Please see Figure 7 and Figure 8 , Figure 7 yes Figure 4 The schematic diagram of the carrier 12 shown in some embodiments is shown. Figure 8 yes Figure 7 A schematic diagram of the structure of the carrier 12 shown from another perspective. Wherein, Figure 7 The viewpoint shown is Figure 8 The perspective of the carrier 12 after it has been flipped.

[0135] In some embodiments, the carrier 12 may generally include a top 121 and a side 122, with the side 122 surrounding the top 121 and fixedly connected to the top 121. The top 121 and side 122 of the carrier 12 may form an optical space 12a, which may communicate with the external space of the carrier 12. The optical space 12a may be used to mount the optical lens of the camera module 100.

[0136] For example, the light inlet 50 can be formed on the carrier 12. The light inlet 50 can be located at the middle of the top 121 of the carrier 12. The carrier 12 can also have a third opening 123, which can be located at opposite ends of the carrier 12 to the light inlet 50. The third opening 123 can be located at the bottom end of the side 122 of the carrier 12. The carrier 12 can have an axial direction (i.e., the direction of extension of the centerline), which can be parallel to the opening direction of the light inlet 50, and the centerline of the carrier 12 can coincide with the centerline of the light inlet 50. For example, the axial direction of the carrier 12 is parallel to the Z direction. For example, the arrangement direction of the light inlet 50 and the third opening 123 is parallel to the axial direction of the carrier 12.

[0137] For example, the carrier 12 may have a third receiving groove 124. The third receiving groove 124 may be formed on the top 121 of the carrier 12 and located on the side surface opposite to the optical space 12a. There may be multiple third receiving grooves 124, arranged at intervals along the circumference of the carrier 12. For example, the number of third receiving grooves 124 may correspond to the number of first receiving grooves 116, such as four third receiving grooves. The third receiving groove 124 may be generally rectangular.

[0138] For example, the carrier 12 may have a second wall surface 125. The second wall surface 125 may be spherical. The second wall surface 125 is located at the top 121 of the carrier 12 and is on the side of the top 121 of the carrier 12 that faces away from the third receiving groove 124. There may be multiple second wall surfaces 125. For example, each second wall surface 125 may correspond one-to-one with a ball bearing groove 115. For instance, there may be four second wall surfaces 125. The second wall surfaces 125 and the third receiving grooves 124 may be spaced apart around the light inlet 50. When both the number of second wall surfaces 125 and the number of third receiving grooves 124 are multiple, the multiple second wall surfaces 125 and the multiple third receiving grooves 124 are arranged alternately.

[0139] The second wall surface 125 may be coplanar with the outer surface of the top 121 of the carrier 12, i.e., the two together form a spherical surface. In some other examples, the second wall surface 125 may also be recessed relative to the surface of the top 121 of the carrier 12, forming a groove.

[0140] For example, the carrier 12 may have a fourth receiving groove 126. The fourth receiving groove 126 may be formed on the side 122 of the carrier 12. The fourth receiving groove 126 may include a plurality of sub-grooves.

[0141] For example, the fourth receiving slot 126 may include a first sub-slot 1261, a second sub-slot 1262, and a third sub-slot 1263. The first sub-slot 1261, the second sub-slot 1262, and the third sub-slot 1263 may all be generally rectangular slots. The first sub-slot 1261 and the third sub-slot 1263 may be arranged opposite to each other, and the second sub-slot 1262 may be located between the first sub-slot 1261 and the second sub-slot 1262. The dimensions of the first sub-slot 1261, the second sub-slot 1262, and the third sub-slot 1263 may be approximately the same.

[0142] For example, the carrier 12 may further include a shock absorber 127. The shock absorber 127 is fixedly connected to the side portion 122 of the carrier 12 and is located on the side of the side portion 122 of the carrier 12 facing away from the optical space 12a, and the shock absorber 127 protrudes relative to the side portion 122 of the carrier 12. There may be multiple shock absorbers 127, which are spaced apart circumferentially along the carrier 12. For example, there may be four shock absorbers 127.

[0143] The anti-collision part 127 may include a protrusion 1271 and an anti-collision pad 1272. The protrusion 1271 is fixedly connected to the side 122 of the carrier 12, and the anti-collision pad 1272 is fixed to the top or bottom surface of the protrusion 1271 in the axial direction of the carrier 12. The hardness of the anti-collision pad 1272 may be lower than that of the protrusion 1271. The anti-collision pad 1272 may be elastic or flexible.

[0144] In some embodiments, the carrier 12 can be integrally molded by insert injection molding. The second wall surface 125 can be formed into a metal insert to improve the wear resistance of the second wall surface 125. Additionally, this also improves the structural strength of the carrier 12.

[0145] Please see Figure 9 , Figure 9 yes Figure 4 The diagram shows the structure of the first magnetic component 2 in some embodiments.

[0146] In some embodiments, the first magnetic component 2 may include a first magnetic element 21 and a second magnetic element 22, at least one of which is magnetic. The third magnetic element 31 and the fourth magnetic element 32 are mutually attractive.

[0147] In some embodiments, the second magnetic element 22 may be magnetic, for example, it may be made of a magnetic material. The first magnetic element 21 may not be magnetic. For example, the first magnetic element 21 may be made of a metallic material with magnetic permeability. Alternatively, the first magnetic element 21 may be made of a non-magnetic ferromagnetic material. For example, the material of the first magnetic element 21 may be a steel sheet. This allows the first magnetic elements 21 to attract each other. In this case, the shape of the first magnetic element 21 is more flexible and can be flexibly configured according to requirements.

[0148] In some other embodiments, the second magnetic element 22 is made of a non-magnetic ferromagnetic material, while the first magnetic element 21 is made of a magnetic material. Alternatively, both the first magnetic element 21 and the second magnetic element 22 are made of magnetic materials.

[0149] For example, the first magnetic element 21 may include a magnetic absorbing sheet 211. The magnetic absorbing sheet 211 is non-magnetic. The first magnetic element 21 may be generally a thin plate structure. The magnetic absorbing sheet 211 may have a first through hole 2111 located at the center of the magnetic absorbing sheet 211. In some examples, the magnetic absorbing sheet 211 may not have a first through hole 2111, which is beneficial for creating a stronger attractive force between the magnetic absorbing sheet 211 and the magnet 221.

[0150] For example, the second magnetic element 22 may include a magnet 221. The magnet 221 is magnetic. The magnet 221 may be generally a thin plate structure. For example, the magnet 221 may be a single magnet block. In other examples, the magnet 221 may also be multiple magnet blocks, such as a Hellbeck magnet array.

[0151] For example, there can be multiple first magnetic elements 21 and multiple second magnetic elements 22. The number of first magnetic elements 21 and the number of second magnetic elements 22 are the same, and the first magnetic elements 21 and the second magnetic elements 22 can be configured in a one-to-one correspondence.

[0152] For example, a first magnetic element 21 and a second magnetic element 22 are arranged opposite to each other. The first magnetic element 21 and the second magnetic element 22 are arranged opposite to each other and spaced apart, and the first magnetic element 21 and the second magnetic element 22 can form a set of magnetic attraction structures, and multiple first magnetic elements 21 and multiple second magnetic elements 22 can form multiple sets of magnetic attraction structures.

[0153] In each set of magnetic attraction structures, in the direction of the thickness of the first magnetic element 21 and the second magnetic element 22, the edge area of ​​the first magnetic element 21 is greater than the edge area of ​​the second magnetic element 22.

[0154] In some embodiments, the surface of the first magnetic element 21 facing the second magnetic element 22 is called the first surface 212, and the surface of the second magnetic element 22 facing the first magnetic element 21 is called the second surface 222. The first surface 212 and the second surface 222 can each be curved surfaces, the first surface 212 can be a concave surface, and the second surface 222 can be a convex surface. The curvature centers of the first surface 212 and the second surface 222 can be located on the side of the second magnetic element 22 away from the first magnetic element 21.

[0155] For example, the first surface 212 and the second surface 222 can each be a sphere, and the centers of the first surface 212 and the second surface 222 can coincide.

[0156] Please refer to the following: Figure 10 , Figure 10 yes Figure 3 A cross-sectional view of a portion of the structure of the camera module 100 shown, cut along point AA. Figure 1 .

[0157] In some embodiments, the carrier 12 is located inside the base 11 and is movably connected to the base 11.

[0158] In some embodiments, the carrier 12 is located within the receiving space 11a of the base 11. The light inlet 50 of the carrier 12 is disposed on the same side as the first opening 113 of the base 11, and the third opening 123 of the carrier 12 is disposed on the same side as the second opening 114 of the base 11. The top 121 of the carrier 12 is opposite to and spaced apart from the top 111 of the base 11, and the side portion 122 of the carrier 12 is spaced apart from and opposite to the side portion 112 of the base 11.

[0159] In some embodiments, the carrier 12 and the base 11 are movably connected by a connecting component 4.

[0160] For example, the connecting component 4 may include a plurality of ball bearings 41. The ball bearings 41 may be divided into multiple groups, each group including one or more balls. It is understood that the balls may be made of wear-resistant materials, and this embodiment does not specifically limit this. For example, the ball bearing 41 may be an individual spherical ball. In some other examples, the ball bearing 41 may also be a protrusion formed on the base 11 or the carrier 12.

[0161] In this configuration, the ball groove 115 of the base 11 is disposed opposite to the second wall surface 125 of the carrier 12, thus the first wall surface 1151 and the second wall surface 125 are disposed opposite to each other. A ball bearing 41 can be accommodated within the ball groove 115, and the ball bearing 41 rolls between the first wall surface 1151 and the second wall surface 125, and the ball bearing 41 is capable of rolling relative to the first wall surface 1151 and / or the second wall surface 125. For example, one ball groove 115 can accommodate one ball, but is not limited to this.

[0162] In this configuration, a second wall surface 125, a ball groove 115, and the ball bearings 41 therein can constitute a set of rolling connection structures. When there are multiple second wall surfaces 125, ball grooves 115, and ball bearings 41, multiple sets of rolling connection structures can be formed. Under the action of the first magnetic component 2, the ball bearings 41 abut against the first wall surface 1151 and the second wall surface 125 respectively. In this case, multiple sets of rolling connection structures can have multiple connection points between the base 11 and the carrier 12, making the connection between the base 11 and the carrier 12 more stable and reliable.

[0163] For example, as described above, both the first wall surface 1151 and / or the second wall surface 125 can be spherical. For instance, when both the first wall surface 1151 and the second wall surface 125 are spherical, their centers can coincide. In this case, the distance between the first wall surface 1151 and the second wall surface 125 remains constant during relative movement, resulting in more accurate and stable movement of the carrier 12 relative to the base 11. When there are multiple ball grooves 115 and multiple second wall surfaces 125, i.e., the anti-shake motor 30 includes multiple rolling connection structures, the centers of the multiple first wall surfaces 1151 can coincide, and also coincide with the centers of the multiple second wall surfaces 125. This allows the carrier 12 to rotate about the axial direction of the base 11 and in any radial direction of the base 11. It is understood that the radial direction of the base 11 is perpendicular to its axial direction.

[0164] For example, the carrier 12 and the base 11 can rotate about a first direction, a second direction, and a third direction. The first direction is parallel to the centerline of the carrier 12, and the second and third directions are perpendicular to the first direction and different from each other. For example, the second direction and the third direction can be perpendicular. For example, the first direction can be parallel to the Z direction, the second direction can be parallel to the X direction, and the third direction can be parallel to the Y direction.

[0165] In this embodiment, by setting the connecting component 4, the carrier 12 can rotate relative to the base 11. The connecting component 4 can support the carrier 12 in the circumferential position of the base 11 and can also support the carrier 12 in the axial position of the base 11, so that the carrier 12 maintains a stable relative position with respect to the base 11.

[0166] Please refer to the following: Figure 11 and Figure 12 , Figure 11 yes Figure 3 A cross-sectional view of a portion of the structure of the camera module 100 shown, cut along point BB. Figure 1 ; Figure 12 yes Figure 3 A cross-sectional view of a portion of the structure of the camera module 100 shown, cut along point CC. Figure 1 .

[0167] In some embodiments, the first magnetic assembly 2 provides pre-stress for the connection between the carrier 12 and the base 11. The first magnetic element 21 is mounted on the base 11, and the second magnetic element 22 is mounted on the carrier 12. The first magnetic element 21 and the second magnetic element 22 are arranged opposite each other. Due to the magnetic attraction between the first magnetic element 21 and the second magnetic element 22, the first magnetic assembly 2 can attract the carrier 12 to the base 11.

[0168] For example, the first magnetic element 21 is located in the first receiving groove 116, and the second magnetic element 22 is located in the third receiving groove 124.

[0169] In this first magnetic assembly 2, both the first magnetic element 21 and the second magnetic element 22 have a thickness direction, a length direction, and a width direction, and their thickness directions, length directions, and width directions are parallel. The thickness direction, length direction, and width direction of the first magnetic element 21 and the second magnetic element 22 can be perpendicular to each other. The length direction of the first magnetic element 21 and the second magnetic element 22 can be circumferential around the center line of the optical space 12a, the thickness direction of the first magnetic element 21 and the second magnetic element 22 can be the arrangement direction of the first magnetic element 21 and the second magnetic element 22, and the length direction of the first magnetic element 21 and the second magnetic element 22 can be perpendicular to the length direction and the thickness direction.

[0170] In some embodiments, when there are multiple first magnetic elements 21 and multiple second magnetic elements 22, that is, when the first magnetic component 2 includes multiple sets of magnetic attraction structures, the multiple sets of magnetic attraction structures can be arranged around the optical space 12a of the carrier 12.

[0171] For example, the multiple sets of magnetic attraction structures of the first magnetic component 2 can be arranged around the center line of the optical space 12a. The first magnetic component 2 is located on the light-incident side of the carrier 12 near the optical lens. The height space occupied by the first magnetic component 2 coincides with a portion of the height space occupied by the optical space 12a.

[0172] For example, multiple sets of magnetic attraction structures can be evenly spaced. In this case, each set of magnetic attraction can generate a pre-pressure that connects the carrier 12 to the base 11. The multiple sets of magnetic attraction structures form multiple forces between the base 11 and the carrier 12. These multiple sets of magnetic attraction structures can cooperate with each other to position the base 11 on the carrier 12 in multiple directions, maintaining a stable relative position between the base 11 and the carrier 12 in multiple directions. When the position of the carrier 12 deviates from that of the base 11, the multiple sets of magnetic attraction structures have a tendency to automatically return the carrier 12 to its center. For example, the multiple sets of magnetic attraction structures have the ability to return to center in the direction around the centerline of the optical space 12a (i.e., the Z direction) and in directions perpendicular to the centerline of the optical space 12a (such as the X and Y directions).

[0173] For example, the magnetic force directions of multiple sets of magnetic attraction structures can all point to the same point on the center line of the carrier 12. For instance, the magnetic attraction directions of the first magnetic element 21 and the second magnetic element 22 of the multiple sets of magnetic attraction structures intersect the center line of the carrier 12 at the same point.

[0174] For example, the resultant force direction of the multiple sets of magnetic attraction structures coincides with the center line of the carrier 12. At this time, the multiple sets of magnetic attraction structures exert the same force on the base 11 and the carrier 12, making the force on the base 11 and the carrier 12 more uniform and simple, which is beneficial to controlling the direction of the resultant force on the carrier 12.

[0175] For example, in multiple sets of magnetic attraction structures, the arrangement direction of the first magnetic element 21 and the second magnetic element 22 in each set of magnetic attraction structures is pointed towards the rotation center of the base 11 and the carrier 12. At this time, the resultant force point of the first magnetic attraction assembly coincides with the rotation center point of the base 11 and the carrier 12. When the carrier 12 moves relative to the base 11, the carrier 12 is not easily deflected or deviated relative to the base 11, which is conducive to the carrier 12 moving in a more accurate manner and facilitates the motion control of the carrier 12.

[0176] For example, when the first surface 212 and the second surface 222 are both curved surfaces, the first surface 212 is recessed away from the second surface 222, and the second surface 222 is protruding towards the first surface 212. In this case, the distance between the first magnetic element 21 and the second magnetic element 22 remains unchanged and will not change due to the relative rotation of the carrier 12 and the base 11, nor will it collide due to the relative rotation of the carrier 12 and the base 11. This helps to reduce the distance between the first magnetic element 21 and the second magnetic element 22, thereby saving space. Furthermore, it also facilitates multi-directional and large-angle movement of the carrier 12 relative to the base 11.

[0177] It is understandable that tolerances and deviations may exist during the manufacturing and assembly of the image stabilization motor. In this application, terms such as "coincident", "intersecting", and "parallel" are relative to the current technological level and are not absolute and strict limitations. A small amount of deviation is allowed, and all situations within the range of deviation are within the protection scope of this application.

[0178] In some other embodiments, when the number of the first magnetic element 21 and the number of the second magnetic element 22 is one, the first magnetic element 21 and / or the second magnetic element 22 are annular and arranged around the optical space 12a.

[0179] In this embodiment, the carrier 12 can float relative to the base 11 by the attraction force of the first magnetic component 2, the carrier 12 is softly connected to the base 11, and the carrier 12 and the base 11 are subjected to pre-pressure.

[0180] Furthermore, by rationally setting the position of the first magnetic component 2, the first magnetic component 2 reuses the height space of the optical space 12a in the extension direction of the center line of the optical space 12a. In the image stabilization motor 30, there is no need to provide additional space for the setting of the first magnetic component 2, which helps to reduce the height of the image stabilization motor 30 and facilitates the thinner design of the image stabilization motor 30.

[0181] In some embodiments, as described above, one of the first magnetic element 21 and the second magnetic element 22 includes a magnetic absorbing sheet 211 and the other includes a magnet 221. In this case, the magnetic absorbing sheet 211 is easy to manufacture, its shape is easy to control, and it is easy to manufacture a thinner magnetic absorbing sheet, which is beneficial to reducing the space occupied by the first magnetic element 21 and the second magnetic element 22, and is beneficial to the miniaturization design of the anti-shake motor 30.

[0182] For example, when the magnetic absorbing piece 211 has a first through hole 2111, the magnetic absorbing piece 211 forms a ring structure. When the magnetic absorbing piece 211 is attracted, it can form a ring magnetic circuit. During the relative movement of the magnetic absorbing piece 211 and the magnet 221, the magnetic absorbing piece 211 has a better centering ability, which is beneficial to keep the position of the carrier 12 relative to the base 11 stable.

[0183] Please continue reading. Figure 12 .

[0184] In some embodiments, at least one ball bearing 41 is located between two first magnetic bearings 21.

[0185] For example, multiple ball bearings 41 and multiple first magnetic components 21 are arranged alternately and spaced apart. Multiple rolling connection structures and magnetic attraction structures are arranged alternately along the circumference of the base 11. The rolling connection structure is the connection contact support point between the carrier 12 and the base 11, and the magnetic attraction structure is the point where the connection force between the carrier 12 and the base 11 is applied. At this time, the connection points and the points where the connection force is applied between the carrier 12 and the base 11 are arranged alternately along the circumference of the carrier 12, the force on the carrier 12 is more balanced, and the movement of the carrier 12 relative to the base 11 is more stable.

[0186] In some other examples, the multiple ball bearings 41 and the multiple first magnetic elements 21 are not arranged alternately. For example, multiple ball bearings 41 may be located between two first magnetic elements 21. This embodiment does not impose strict limitations on this.

[0187] Please refer to the following: Figure 4 and Figure 13 , Figure 13 yes Figure 3 A cross-sectional view of a portion of the structure of the camera module 100 shown, cut along point AA. Figure 2 .

[0188] In some embodiments, in the camera module 100, the focus motor 40 and the sensor assembly 10 can be fixedly connected to the carrier 12.

[0189] For example, the focusing motor 40 may be generally annular, forming a mounting space 40a for mounting the lens element of the optical lens. The focusing motor 40 is located within the optical space 12a of the carrier 12 and is fixedly connected to the side 122 of the carrier 12. For example, the focusing motor 40 is bonded to the carrier 12 by filling the space between the focusing motor 40 and the side 122 of the carrier 12 with adhesive. Thus, the focusing motor 40 can move with the carrier 12 relative to the base 11.

[0190] For example, the sensor assembly 10 may include a photosensitive element. The sensor assembly 10 may be fixedly connected to the end of the focusing motor 40 facing away from the light entrance port 50, with the photosensitive element facing the light entrance port 50 so that light passes through the mounting space 40a from the light entrance port 50 and enters the photosensitive element. The sensor assembly 10 may be fixedly connected to the focusing motor 40 by adhesive, thus the sensor assembly 10 is fixedly connected to the carrier 12. Furthermore, the sensor assembly 10 is capable of moving relative to the base 11 along with the carrier 12.

[0191] In some embodiments, the bottom shell 13 may be fixedly connected to the base 11. Exemplarily, the bottom shell 13 may be generally plate-shaped. The bottom shell 13 may be fixed to the second opening 114 of the base 11 and spaced apart from the sensor assembly 10. The bottom shell 13 is also spaced apart from the carrier 12.

[0192] Please see Figure 14 , Figure 14 yes Figure 4 The diagram shows the structure of the second magnetic component 3 in some embodiments.

[0193] In some embodiments, the second magnetic component 3 may include a third magnetic element 31 and a fourth magnetic element 32. The third magnetic element 31 and the fourth magnetic element 32 may be disposed opposite to each other. Both the third magnetic element 31 and the fourth magnetic element 32 may be made of magnetic materials and both possess magnetic properties.

[0194] For example, the third magnetic element 31 may be generally disk-shaped. The fourth magnetic element 32 may be generally block-shaped. In the thickness direction of the third magnetic element 31 and the fourth magnetic element 32, the edge contour area of ​​the third magnetic element 31 is larger than the edge contour area of ​​the fourth magnetic element 32. In some other examples, the edge contour area of ​​the fourth magnetic element 32 may be larger than the edge contour area of ​​the third magnetic element 31.

[0195] For example, the surface of the third magnetic member 31 facing the fourth magnetic member 32 is the third surface 311, which can be a plane. For example, the third surface 311 can be a circular plane. In some other examples, the third surface 311 can also be a curved surface, with the third surface 311 recessed away from the third magnetic member 31. For example, the third surface 311 is a sphere. When the third surface 311 is a concave curved surface, it is beneficial to center the magnetic directions of the third magnetic member 31 and the fourth magnetic member 32. Furthermore, it is beneficial to avoid collisions caused by the movement of the fourth magnetic member 32 relative to the third magnetic member 31, and to reduce the distance between the third magnetic member 31 and the fourth magnetic member 32.

[0196] For example, the surface of the fourth magnetic member 32 facing the third magnetic member 31 is the fourth surface 321, which can be a plane. In some other examples, the fourth surface 321 can also be a curved surface, protruding towards the third magnetic member 31. For example, the fourth surface 321 is a hemisphere.

[0197] Please see Figure 15 , Figure 15 yes Figure 3 A cross-sectional view of a portion of the structure of the camera module 100 shown, cut along point AA. Figure 3 .

[0198] In some embodiments, the second magnetic component 3 is installed inside the housing component 1, that is, the second magnetic component 3 is located in the accommodating space. The third magnetic component 31 can be fixedly connected to the base 11, and the fourth magnetic component 32 can be fixedly connected to the carrier 12. The third magnetic component 31 and the fourth magnetic component 32 are arranged opposite to each other and spaced apart, and the third magnetic component 31 and the fourth magnetic component 32 repel each other.

[0199] For example, the third magnetic component 31 can be mounted on the side of the bottom housing 13 facing the light inlet 50, and the fourth magnetic component 32 can be mounted on the side of the sensor assembly 10 facing the bottom housing 13. In this example, the fourth magnetic component 32 is fixedly connected to the carrier 12 via the sensor assembly 10 and the focus motor 40, reducing the number of components connecting the carrier 12 and the fourth magnetic component 32 and simplifying the structure of the camera module 100. In other examples, the fourth magnetic component 32 can also be fixed to the carrier 12 via structural components or directly.

[0200] For example, the third magnetic element 31 and the fourth magnetic element 32 are arranged parallel to the axial direction of the carrier 12, and the repulsive force of the third magnetic element 31 and the fourth magnetic element 32 coincides with the axis of the carrier 12. For example, the center line of the optical space 12a can pass through the third magnetic element 31 and the fourth magnetic element 32. It is understood that the spaces in the camera module 100 used for mounting the sensor assembly 10 and for mounting the second magnetic assembly 3 are not part of the optical space 12a.

[0201] In this embodiment, since the third magnetic component 31 and the fourth magnetic component 32 repel each other, the third magnetic component 31 supports the fourth magnetic component 32, that is, the base 11 supports the carrier 12, and the base 11 supports the carrier 12 through the connecting component 4. The second magnetic component 3 causes the carrier 12 to press against the base 11 through the connecting component 4. Furthermore, the closer the third magnetic component 31 and the fourth magnetic component 32 are, the greater the repulsive force between them, which is beneficial to improving the vibration resistance and impact resistance of the camera module 100.

[0202] Additionally, the first magnetic component 2 (see also...) Figure 11 The first magnetic component 2 and the second magnetic component 3 are located at opposite ends of the carrier 12 in its axial direction. The first magnetic component 2 provides attractive force and the second magnetic component 3 provides repulsive force, making the movable connection between the carrier 12 and the base 11 more reliable.

[0203] In some embodiments, in the arrangement direction of the third magnetic element 31 and the fourth magnetic element 32, the projection of the outline edge of the third magnetic element 31 covers the projection of the outline edge of the fourth magnetic element 32. This coverage, as referred to in this application, may also include situations where the projections of the third magnetic element 31 and the fourth magnetic element 32 are misaligned or deviated due to manufacturing or assembly tolerances. Therefore, when the carrier 12 rotates relative to the base 11, the fourth magnetic element 32 moves relative to the third magnetic element 31. The third magnetic element 31 has a larger area, enabling it to exert a repulsive force on the fourth magnetic element 32 after the fourth magnetic element 32 moves. Furthermore, the larger area of ​​the fourth magnetic element 32 facilitates the centering of the third magnetic element 31 relative to the fourth magnetic element 32, thereby helping the carrier 12 return to the center position of the base 11.

[0204] In addition, compared with the embodiment where the fourth magnetic element 32 has a larger area, in this embodiment, the third magnetic element 31 is fixed and the magnetic field range is larger. During the movement of the fourth magnetic element 32 relative to the third magnetic element 31, the position of the fourth magnetic element 32 has less impact on the magnetic repulsion between the two, which is conducive to the stability of the third magnetic element 31 and the fourth magnetic element 32 during relative movement, and thus conducive to the stability of the carrier 12 and the base 11 during relative movement.

[0205] It is understood that, as mentioned above, the multiple magnetic attraction structures of the first magnetic component 2 can be arranged around the centerline of the optical space 12a. The first magnetic component 2 is located on the light-incident side of the carrier 12 near the optical lens. Here, the light-incident side of the first magnetic component 2 near the optical lens refers to the direction of extension of the centerline of the carrier 12 (such as the Z direction), and the first magnetic component 2 is at least closer to the light-incident port 50 than the sensor component 10.

[0206] Please see Figure 16 , Figure 16 yes Figure 4The diagram shows a structural schematic of the driving magnetic component 5 in some embodiments.

[0207] In some embodiments, the driving magnetic component 5 may include a driving magnet 51 and a driving coil 52.

[0208] The driving magnet 51 may include a first driving magnet 511, a second driving magnet 512, and a third driving magnet 513. The driving coil 52 includes a first driving coil 521, a second driving coil 522, and a third driving coil 523.

[0209] Please see Figure 17 and Figure 18 , Figure 17 yes Figure 3 The camera module 100 shown is a cross-sectional view taken along point AA in some embodiments. Figure 18 yes Figure 3 The camera module 100 shown is a cross-sectional view taken along DD in some embodiments.

[0210] In some embodiments, the driving magnetic component 5 may be mounted on the housing component 1.

[0211] For example, the drive coil 52 can be installed in the second receiving slot 117 of the base 11. For instance, the first drive coil 521 can be installed in the first slot 1171, the second coil can be installed in the second slot 1172, and the third coil can be installed in the third slot 1173.

[0212] For example, the driving magnet 51 can be installed in the fourth receiving slot 126 of the carrier 12. For instance, the first driving magnet 511 is installed in the first sub-slot 1261, the second driving magnet 512 is installed in the second sub-slot 1262, and the third driving magnet 513 is installed in the third sub-slot 1263.

[0213] For example, a driving magnet 51 and a driving coil 52 are correspondingly arranged to form a driving structure. For instance, a first driving coil 521 is arranged corresponding to a first driving magnet 51, a second driving coil 522 is arranged corresponding to a second driving magnet 51, and a third driving coil 523 is arranged corresponding to a third driving magnet 51. Each driving structure can drive the carrier 12 to rotate relative to the base 11 in one direction. Through the three driving structures, the carrier 12 can rotate relative to the base 11 in three directions. For example, the three directions can be perpendicular to each other.

[0214] Please refer to the following: Figure 11 and Figure 19 , Figure 19 yes Figure 4 The diagram shows a partial structural representation of the first magnetic component 2 in some other embodiments. Figure 19 The first magnetic component 2 shown in the embodiment includes Figure 9 Most of the technical features of the first magnetic component 2 shown in the embodiment will not be repeated here for the same technical features. The following mainly describes the differences between the two.

[0215] Figure 19 The first magnetic component 2 shown in the embodiment and Figure 9 The main difference of the first magnetic component 2 shown in the embodiment lies in the size setting.

[0216] In some embodiments, in the first magnetic component 2, the length of the magnet 221 is greater than the length of the magnetic chuck 211, and the width of the magnet 221 is less than the width of the magnetic chuck 211. In this case, when the magnet 221 and the magnetic chuck 211 move relative to each other in the length direction (e.g., rotate), the longer length of the magnet 221 results in stronger magnetism, which helps the magnetic chuck 211 return to its centered position after moving relative to the magnet 221, thus facilitating the centering of the carrier 12 relative to the base 11 after movement. Furthermore, when the magnet 221 and the magnetic chuck 211 move relative to each other in the height direction (e.g., rotate), the higher height of the magnetic chuck 211 results in stronger magnetic attraction between the magnetic chuck 211 and the magnet 221, which helps the magnetic chuck 211 return to its centered position after moving relative to the magnet 221, thus facilitating the centering of the carrier 12 relative to the base 11 after movement.

[0217] For example, the width ratio of the magnet 221 to the width of the magnetic absorbing piece 211 is greater than or equal to 1.5. In this case, by optimizing the width ratio of the magnet 221 and the magnetic absorbing piece 211, the magnet 221 and the magnetic absorbing piece 211 can have suitable magnetic attraction force and centering ability.

[0218] For example, the height ratio of the magnetic chuck 211 to the height of the magnet 221 is greater than or equal to 1.5. In this case, by optimizing the height ratio of the magnet 221 and the magnetic chuck 211, the magnet 221 and the magnetic chuck 211 can have suitable magnetic attraction and centering ability.

[0219] Please see Figure 20 , Figure 20 yes Figure 4 The diagram shows a partial structural schematic of the first magnetic component 2 in some embodiments. Figure 20 The first magnetic component 2 shown in the embodiment includes Figure 9 Most of the technical features of the first magnetic component 2 shown in the embodiment will not be repeated here for the same technical features. The following mainly describes the differences between the two.

[0220] Figure 20 The first magnetic component 2 shown in the embodiment and Figure 9 The main difference of the first magnetic component 2 shown in the embodiment lies in the structural design.

[0221] In some embodiments, the first magnetic component 2 further includes a shield 223, which covers the side of the magnet 221 away from the magnetic absorbing sheet 211.

[0222] For example, a magnet 221 may include multiple magnets and form a Heilbeck magnet array.

[0223] For example, the first magnetic element 21 includes a magnetic absorbing sheet 211, and the second magnetic element 22 includes a magnet 221. A shielding cover 223 is disposed on the side of the second magnetic element 22 opposite to the first magnetic element 21.

[0224] In this embodiment, the anti-shake motor 30 generally contains other components that have magnetic fields or utilize magnetic fields. The magnet 221 of the first magnetic component 2 has magnetism. A shield 223 is provided on the side facing away from the magnetic absorbing sheet 211 to prevent the magnetism of the magnet 221 from affecting other magnetic fields on the side of the magnet 221 facing away from the magnetic absorbing sheet 211, thereby improving the reliability of the anti-shake motor 30.

[0225] Please see Figure 21 , Figure 21 yes Figure 4 The diagram shows a partial structural representation of the second magnetic component 3 in some other embodiments. Figure 21 The second magnetic component 3 shown in the embodiment includes Figure 14 Most of the technical features of the second magnetic component 3 shown in the embodiment will not be repeated here for the same technical features. The following mainly describes the differences between the two.

[0226] Figure 21 The second magnetic component 3 shown in the embodiment and Figure 14 The main difference of the second magnetic component 3 shown in the embodiment lies in the shape setting.

[0227] In some embodiments, in the second magnetic component 3, the fourth surface 321 of the fourth magnetic element 32 is curved and protrudes towards the third magnetic element 31. Exemplarily, the fourth surface 321 is a conical surface or a spherical surface.

[0228] In this embodiment, the magnetic force of the third magnetic element 31 is more concentrated at the end near the fourth magnetic element 32, which helps to center the magnetic force directions of the third magnetic element 31 and the fourth magnetic element 32. Furthermore, it helps to prevent collisions caused by the movement of the fourth magnetic element 32 relative to the third magnetic element 31, and helps to reduce the distance between the third magnetic element 31 and the fourth magnetic element 32.

[0229] In some embodiments, the third magnetic element 31 may include multiple magnets, and the third magnetic element 31 is formed by splicing multiple magnets together.

[0230] Please see Figure 22 , Figure 22 yes Figure 4The diagram shows a partial structural schematic of the second magnetic component 3 in some embodiments. Figure 22 The second magnetic component 3 shown in the embodiment includes Figure 14 Most of the technical features of the second magnetic component 3 shown in the embodiment will not be repeated here for the same technical features. The following mainly describes the differences between the two.

[0231] Figure 22 The second magnetic component 3 shown in the embodiment and Figure 14 The main difference of the second magnetic component 3 shown in the embodiment lies in the shape setting.

[0232] In some embodiments, the third magnetic element 31 in the second magnetic component 3 is a ring structure. For example, the third surface 311 is a ring-shaped plane. In this case, the magnetic field of the third magnetic element 31 is stronger at the ring structure, and the magnetic repulsion between the third magnetic element 31 and the fourth magnetic element 32 is more easily centered. This is beneficial for maintaining the stability of the repulsion between the fourth magnetic element 32 and the third magnetic element 31, and also for the fourth magnetic element 32 to return to center after moving relative to the third magnetic element 31.

[0233] For example, the ratio of the outer diameter to the inner diameter of the third magnetic element 31 is greater than or equal to 1.3. In this case, by optimizing the ratio of the outer diameter to the inner diameter of the third magnetic element 31, a suitable magnetic repulsion force and centering ability are achieved between the third magnetic element 31 and the fourth magnetic element 32.

[0234] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0235] It should be noted that all the above figures are exemplary illustrations of this application and do not represent the actual size of the product. Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application.

[0236] The above are merely some embodiments and implementation methods of this application. The scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
