Description
Technical Field
[0001] The present application relates to the field of imaging, and in particular to a driving motor and related products. Background Art
[0002] With the popularity and development of smart phones, mobile phone photography has become a common way of shooting, and users have higher and higher requirements for the shooting quality of electronic devices. At present, telephoto lenses on the market usually adopt a periscope structure to achieve miniaturization. The periscope structure usually includes a light folding element and a lens group arranged from the object side to the image side, and the light folding element is driven by an anti-shake motor to achieve optical image stabilization. However, the current anti-shake motor has low driving accuracy and high focus offset, resulting in poor final image quality. Summary of the invention
[0003] The embodiments of the present application provide a driving motor and related products including the driving motor, aiming to provide a driving motor and related products including the driving motor with high anti-shake accuracy and small focus offset.
[0004] In the first aspect, a driving motor is provided. The driving motor has a light inlet and a light outlet. The driving motor comprises: a base; a first bracket movably connected to the base, the first bracket comprising a mounting bevel, the side of the mounting bevel facing the light inlet and the light outlet is the mounting side, and the mounting side is used to mount the first optical element; and a first driving mechanism, which is used to drive the first bracket to rotate around a first axis relative to the base, and the first axis is parallel to the mounting bevel; wherein, light is incident on the driving motor from the light inlet along a first direction, and after being reflected by the first optical element, the light is emitted from the driving motor from the light outlet along a second direction, the first direction intersects with the second direction, and the first axis is located on the mounting side of the mounting bevel and is perpendicular to the plane where the first direction and the second direction are located.
[0005] It can be understood that compared with some driving motors driving the first optical element to rotate relative to the base around the first axis to achieve the optical image stabilization function. Among them, the first axis is perpendicular to the plane where the first direction and the second direction are located, and the first axis is located on the mounting bevel of the mover, or on the side of the mounting bevel facing away from the light exit hole. This makes the focus offset larger when the driving motor drives the first optical element to rotate around the first axis for optical image stabilization, which makes the modulation transfer function of the entire camera module drop significantly, and the anti-shake accuracy is low, affecting the imaging quality. The first axis of the driving motor in this embodiment is located on the side of the mounting bevel close to the light exit hole, that is, the mounting side of the mounting bevel. The first axis is perpendicular to the plane where the first direction and the second direction are located. In this way, when the driving motor drives the first optical element to rotate around the first axis, the focus offset is small, thereby effectively reducing the influence of the focus offset on the modulation transfer function, which is beneficial to improve the anti-shake accuracy of the entire camera module and improve the imaging quality.
[0006] In one possible implementation, the drive motor also includes a second bracket and a second drive mechanism, the second bracket is movably connected between the base and the first bracket, the second drive mechanism is used to drive the second bracket and the first bracket to rotate around a second axis relative to the base, the second axis passes through the mounting bevel and is parallel to the second direction.
[0007] It is understandable that, compared to some driving motors driving the first optical element to rotate around the second axis to achieve the optical image stabilization function, the second axis is parallel to the first direction. Such anti-shake will cause the exit surface of the first optical element to have an inclination angle with the incident surface of the subsequent focusing component, thereby causing the modulation transfer function of the entire camera module to drop significantly, and the anti-shake accuracy is low, affecting the imaging quality. In this embodiment, the second axis of the driving motor is parallel to the second direction. When the first optical element rotates around the second axis driven by the driving motor for anti-shake, the exit surface of the first optical element can always remain parallel to the incident surface of the subsequent focusing component, thereby effectively improving the overall anti-shake accuracy of the driving motor, reducing the impact on the modulation transfer function, and helping to improve the imaging quality of the camera module.

The drive motor also includes a first group of support members, the first group of support members includes a plurality of first support members, some of the first support members are connected between the first connection portion and the second bracket, and another part of the first support members are connected between the second connection portion and the second bracket. In this way, the first connection portion of the first bracket can be movably connected to the second bracket through a part of the first support members, and the second connection portion can be movably connected to the second bracket through another part of the first support members. At the same time, both the first connection portion and the second connection portion can be arranged close to the light exit hole, so as to facilitate the first axis to be arranged on the installation side of the installation slope to improve the anti-shake accuracy.

In this way, when the first optical element is mounted on the driving motor, the center point of the second group of supports is located on the installation side, and the center point of the second group of supports is relatively close to the center of gravity of the first optical element, the first bracket and the second bracket as a whole. In this way, on the one hand, the anti-interference ability of the driving motor can be effectively enhanced when rotating around the second axis for anti-shake; on the other hand, the power consumption of the driving motor can also be reduced, which is conducive to extending the battery life of the electronic device and improving the user experience.

[0030] In a possible implementation, the distance between the first axis and the mounting bevel is greater than 0.01 mm; and / or the distance between the first axis and the mounting bevel is greater than or equal to 5 mm. In this way, the first axis can be located on the mounting side and have a certain distance from the mounting bevel, which is conducive to reducing the focus offset, thereby effectively reducing the impact of the focus offset on the modulation transfer function, which is conducive to improving the anti-shake accuracy of the entire camera module and improving the imaging quality.
[0031] In a possible implementation, the first bracket and the light inlet are arranged in a first direction, the first bracket and the light outlet are arranged in a second direction, a first connection part and a second connection part are provided on a side of the first bracket close to the light outlet, the first connection part and the second connection part are opposite and spaced apart, and the arrangement direction of the first connection part and the second connection part is parallel to the first axis; the driving motor also includes a first group of support members, the first group of support members includes a plurality of first support members, the first connection part is rotatably connected to the base through a part of the first support members, and the second connection part is rotatably connected to the base through another part of the first support members. In this way, the first bracket is directly and movably connected to the base, which is conducive to reducing the error between the first bracket and the base caused by assembly, etc., and improving the movement accuracy.
[0032] In the second aspect, an anti-shake component is provided. The anti-shake component includes a first optical element and the above-mentioned driving motor, the first optical element includes an optical path folding element, the optical path folding element includes a first surface, a second surface and a third surface, the first surface is perpendicular to the third surface, the second surface is arranged toward the first surface and the third surface, and connects the first surface and the second surface, the first surface and the third surface are both transmissive surfaces, the second surface is a reflective surface, the first surface is arranged opposite to the light inlet hole, and the third surface is arranged opposite to the light outlet hole; the first optical element has a light inlet axis and a light outlet axis, the light inlet axis is parallel to the first direction, and the light outlet axis is parallel to the second direction.
[0033] It can be understood that the first axis of the drive motor of the anti-shake assembly of this embodiment is located on the side of the mounting bevel close to the light exit hole, that is, the mounting side of the mounting bevel. The first axis is perpendicular to the plane where the first direction and the second direction are located. In this way, when the drive motor drives the first optical element to rotate around the first axis, the focus offset is small, thereby effectively reducing the influence of the focus offset on the modulation transfer function, which is beneficial to improving the anti-shake accuracy of the entire camera module and improving the imaging quality.
[0034] In a third aspect, an anti-shake component is provided. The anti-shake component includes a first optical element and the above-mentioned driving motor, the first optical element includes an optical path folding element, the optical path folding element includes a reflecting surface and a mounting surface, the reflecting surface is arranged opposite to the mounting surface, the mounting surface faces the mounting inclined surface of the first bracket, and is fixedly connected to the mounting inclined surface, and the reflecting surface is arranged opposite to the mounting inclined surface; the first optical element has a light input axis and a light output axis, the light input axis is parallel to the first direction, and the light output axis is parallel to the second direction.
[0035] It can be understood that the first axis of the drive motor of the anti-shake assembly of this embodiment is located on the side of the mounting bevel close to the light exit hole, that is, the mounting side of the mounting bevel. The first axis is perpendicular to the plane where the first direction and the second direction are located. In this way, when the drive motor drives the first optical element to rotate around the first axis, the focus offset is small, thereby effectively reducing the influence of the focus offset on the modulation transfer function, which is beneficial to improving the anti-shake accuracy of the entire camera module and improving the imaging quality.
[0036] Secondly, compared to the anti-shake component whose optical path folding element is a reflective prism, the first surface, the second surface and the third surface of the reflective prism are all solid surfaces, and the transmission of light between the first surface and the third surface is all located inside the reflective prism. The refractive index inside the reflective prism is relatively high, which increases the optical path requirement of the entire camera module, the focusing path of the focusing component is longer, and the overall size of the module is longer. The optical path folding element in this embodiment is a reflective plane mirror, and the reflecting surface of the optical path folding element is exposed to the air. In this way, the transmission of light between the light inlet and the light outlet is all located in the air. The refractive index in the air is relatively low, which is conducive to reducing the optical path requirement of the camera module, thereby shortening the focusing path of the focusing component, and is conducive to reducing the size of the entire module in the second direction, thereby realizing the miniaturization of the camera module.
[0037] In a possible implementation, the drive motor also includes an optical mount, at least a portion of which is fixedly connected between the optical path folding element and the mounting bevel, and the strength of the optical mount is greater than the strength of the portion of the first bracket where the mounting bevel is located.
[0038] It is understandable that, compared with the direct contact between the optical path folding element and the mounting bevel of the first bracket, the strength of the portion of the first bracket where the mounting bevel is located is relatively low, making the portion where the mounting bevel is located susceptible to deformation due to impact or in a high temperature environment, thereby affecting the surface accuracy of the contact surface between the optical path folding element and the mounting bevel, and reducing the optical quality. The optical path folding element of this embodiment is indirectly fixed to the mounting bevel through an optical mounting part, the optical path folding element is not in direct contact with the mounting bevel, and the strength of the optical mounting part is relatively high, making the optical mounting part less susceptible to deformation due to impact or in a high temperature environment, which is beneficial to ensuring the surface accuracy of the contact surface between the optical path folding element and the optical mounting part, and ensuring the optical quality of the optical path folding element.
[0039] In one possible implementation, the optical mounting member includes a first mounting member and a second mounting member, the first mounting member and the second mounting member are spaced apart, at least a portion of the first mounting member is fixedly connected between the optical path folding element and the mounting bevel, and at least a portion of the second mounting member is fixedly connected between the optical path folding element and the mounting bevel.
[0040] It can be understood that compared to the optical mounting part which is a whole, that is, the first mounting part and the second mounting part are integrally formed. When the driving motor is hit, the stress of the optical mounting part is more concentrated and will be transmitted inward to the first optical element, causing the first optical element to be pulled, affecting the surface accuracy of the first optical element and reducing the optical quality. In this embodiment, the optical mounting part is arranged as two independent and separately arranged first mounting parts and second mounting parts. In this way, when the driving motor is hit, the first mounting part and the second mounting part can respectively withstand stresses in different directions, thereby preventing the first optical element from being pulled by stresses in different directions, thereby reducing its own surface accuracy and affecting the optical quality.
[0041] In a possible implementation, the first optical element further includes a first lens, which is located on the light incident side of the optical path folding element, and has a positive optical power. In this way, the first lens can have a light-gathering effect, and the first lens can allow as much external light as possible to enter the optical path folding element, thereby increasing the amount of light entering the entire first optical element, which is beneficial to increasing the amount of light entering the subsequent focusing assembly.
[0042] In a possible implementation, the first optical element further includes a second lens, which is located on the light-emitting side of the optical path folding element, and has a negative optical power. In this way, the second lens has an astigmatism effect, and the second lens can diffuse as much light as possible emitted by the optical path folding element, thereby increasing the light output of the entire first optical element, which is beneficial to increasing the light input of the subsequent focusing component.
[0043] In a possible implementation, the projection point of the first axis on the plane where the first direction and the second direction are located is the first point, and the distance between the first point and the light-emitting axis is less than or equal to 3 mm. In this way, the distance between the first point and the light-emitting axis is relatively close, which is conducive to improving the anti-shake accuracy of the anti-shake component.
[0044] In a possible implementation, the driving motor further includes a second bracket and a second driving mechanism, the second bracket is movably connected between the base and the first bracket, and the second driving mechanism is used to drive the second bracket and the first bracket to rotate relative to the base around a second axis, the second axis intersects with the first axis, the second axis passes through the light exit hole and the mounting inclined surface, and is parallel to the second direction; the distance between the second axis and the light exit axis is less than or equal to 3 mm. In this way, the distance between the second axis and the light exit axis is relatively close, which is conducive to improving the anti-shake accuracy of the anti-shake component.
[0045] In a possible implementation, the drive motor further includes a second set of support members, and the second bracket is slidably connected to the base through the second set of support members; the distance between the center point of the second set of support members and the center of gravity of the first bracket, the second bracket, and the first optical element as a whole is less than or equal to 0.3 mm. In this way, the distance between the center point of the second set of support members and the center of gravity of the first bracket, the second bracket, and the first optical element as a whole is relatively close. On the one hand, it can effectively enhance the anti-interference ability of the drive motor when rotating around the second axis for anti-shake; on the other hand, it can also reduce the power consumption of the drive motor, which is conducive to extending the battery life of the electronic device and improving the user experience.
[0046] In a fourth aspect, a camera module is provided. The camera module includes a focusing assembly, an image sensor and the above-mentioned anti-shake assembly, the focusing assembly is located on the light-emitting side of the anti-shake assembly, and the image sensor is located on the light-emitting side of the focusing assembly. It can be understood that the first axis of the driving motor of the camera module of this embodiment is located on the side of the mounting bevel close to the light-emitting hole, that is, the mounting side of the mounting bevel. The first axis is perpendicular to the plane where the first direction and the second direction are located. In this way, when the driving motor drives the first optical element to rotate around the first axis, the focus offset is small, thereby effectively reducing the influence of the focus offset on the modulation transfer function, which is beneficial to improving the anti-shake accuracy of the entire camera module and improving the imaging quality.
[0047] In a fifth aspect, an electronic device is provided. The electronic device comprises a device housing and the above-mentioned camera module, wherein the camera module is arranged in the device housing. The camera module of the electronic device in this embodiment has high anti-shake accuracy and high imaging quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0113] The embodiments of the present application are described below in conjunction with the accompanying drawings in the embodiments of the present application.
[0114] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the relative position relationship after connection remains unchanged. "Rotational connection" means that the two are connected to each other and can rotate relative to each other after connection. "Sliding connection" means that the two are connected to each other and can slide relative to each other after connection. The directional terms mentioned in the embodiments of the present application, such as "up", "down", "left", "right", "inside", "outside", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. "Multiple" means at least two.
[0115] In the embodiments of the present application, the terms "first", "second", "third", and "fourth" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first", "second", "third", and "fourth" may explicitly or implicitly include one or more of the features.
[0116] In the implementation manner of the present application, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.
[0117] References to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in another embodiment", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.
[0118] It is to be understood that the specific implementations described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.
[0119] Figure 1 It is a structural diagram of an implementation of an electronic device 1000 provided in an implementation manner of the present application. Figure 2 yes Figure 1 The cross-sectional structure diagram of an electronic device 1000 in one embodiment is shown along AA.
[0120] like Figure 1 and Figure 2 As shown, the electronic device 1000 can be a device with a camera module, such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, a vehicle-mounted device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses or a VR helmet. Figure 1 The electronic device 1000 in the illustrated embodiment is described by taking a mobile phone as an example.
[0121] like Figure 1 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 1 The following figures and the related drawings only schematically illustrate some components of the electronic device 1000, and the actual shapes, sizes, positions and structures of these components are not subject to Figure 1 In addition, when the electronic device 1000 is a device of some other form, the electronic device 1000 may not include the screen 300 .
[0122] For ease of description, the width direction of the electronic device 1000 is defined as the X axis. The length direction of the electronic device 1000 is defined as the Y axis. The thickness direction of the electronic device 1000 is defined as the Z axis. It is understood that the coordinate system setting of the electronic device 1000 can be flexibly set according to specific actual needs.
[0123] In this embodiment, the device housing 200 may include a frame 201 and a back cover 202. The back cover 202 is fixed to the frame 201. Exemplarily, the back cover 202 may be fixedly connected to the frame 201 by adhesive. The back cover 202 may also be an integrally formed structure with the frame 201, that is, the back cover 202 and the frame 201 are an integral structure.
[0124] In addition, the screen 300 may be located on a side of the frame 201 away from the back cover 202. In this case, the screen and the back cover 202 are located on both sides of the frame 201. The screen 300, the frame 201 and the back cover 202 together enclose the interior of the electronic device 1000. The interior of the electronic device 1000 may be used to place components of the electronic device 1000, such as a battery, a receiver or a microphone. The screen 300 may be a flat screen or a curved screen.
[0125] For example, the camera module 100 may be a periscope camera module. The camera module 100 may be located inside the electronic device 1000. The camera module 100 may be fixed to the side of the screen 300 facing the back cover 202. The back cover 202 may be provided with a light-transmitting hole 203. The shape of the light-transmitting hole 203 is not limited to the shape of the light-transmitting hole 203. Figure 1 The light-transmitting hole 203 connects the inside of the electronic device 1000 to the outside of the electronic device 1000. Light outside the electronic device 1000 can enter the inside of the electronic device 1000 through the light-transmitting hole 203. The camera module 100 can collect ambient light entering the inside of the electronic device 1000.
[0126] Figure 3 yes Figure 2 The illustrated diagram is a schematic structural diagram of an anti-shake component of the camera module 100 in some implementations. Figure 4 yes Figure 3 The illustrated diagram is a schematic diagram of the exploded structure of an anti-shake component in some implementations.
[0127] like Figures 2 to 4 As shown, the camera module 100 may include an anti-shake component 1, a focus component 2, and an image sensor 3. Light outside the electronic device 1000 may enter the inside of the electronic device 1000 through the light-transmitting hole 203, and then pass through the anti-shake component 1 and the focus component 2 in sequence, and finally be imaged on the image sensor 3. Exemplarily, the anti-shake component 1, the focus component 2, and the image sensor 3 may be arranged in sequence along the X-axis direction.
[0128] In some embodiments, one or more lenses / prisms with a reflective function may be additionally provided between the focusing assembly 2 and the image sensor 3 to change the propagation path of the light between the focusing assembly 2 and the image sensor 3, so that after the light is emitted from the focusing assembly 2, it may be reflected once or multiple times and finally enter the image sensor 3. In this way, the overall light path of the camera module 100 becomes longer, which is conducive to increasing the zoom multiple of the camera module 100.
[0129] Exemplarily, the anti-shake assembly 1 may include a driving motor 1a and a first optical element 1b. The first optical element 1b may be mounted on the driving motor 1a. The driving motor 1a may drive the first optical element 1b to rotate around a first axis (not shown) and / or a second axis (not shown) to achieve optical image stabilization (OIS) of the camera module 100 and improve the imaging quality of the camera module 100.
[0130] Exemplarily, the focus assembly 2 may include a focus motor (not shown) and a second optical element (not shown). The second optical element may be mounted on the focus motor. The focus motor may control the second optical element to move along the optical axis to achieve auto focus (AF). The second optical element may include at least one lens. The first optical element and the second optical element may together constitute an optical system of the camera module 100.
[0131] Figure 5 yes Figure 3 The illustrated diagram is a schematic diagram of the exploded structure of the first optical element 1b of the anti-shake assembly 1 in some embodiments. Figure 6 yes Figure 3 The illustrated diagram is a partial cross-sectional structural diagram of an embodiment of the anti-shake assembly 1 cut along B1 - B1 .
[0132] like Figure 5 and Figure 6As shown, the first optical element 1b may include an incident surface 101, a reflective surface 102 and an exit surface 103. Light may enter the interior of the first optical element 1b from the incident surface 101 of the first optical element 1b, and after being reflected by the reflective surface 102, be emitted from the exit surface 103. The light-incoming axis T1 of the first optical element 1b may be perpendicular to the incident surface 101. The light-exiting axis T2 of the first optical element 1b may be perpendicular to the exit surface 103. In this embodiment, the light-incoming axis T1 of the first optical element 1b may be parallel to the Z-axis direction, and the light-exiting axis T2 may be parallel to the X-axis direction. Among them, the first optical element 1b may include an optical path folding element 104 and a first lens 105. The first lens 105 may be fixed on the light-incoming side of the optical path folding element 104. At this time, the incident surface of the first lens 105 may constitute the incident surface 101 of the first optical element 1b.
[0133] Exemplarily, the optical path folding element 104 may be a reflective prism. The cross-section of the optical path folding element 104 may be a triangle. Among them, the optical path folding element 104 may include a first surface 1041, a second surface 1042 and a third surface 1043. The first surface 1041 and the third surface 1043 may be perpendicular to each other. The second surface 1042 may be connected between the first surface 1041 and the third surface 1043. The first surface 1041 may be perpendicular to the light input axis. The third surface 1043 may be perpendicular to the light output axis. Both the first surface 1041 and the third surface 1043 may be transmission surfaces. The second surface 1042 may be a reflection surface. In this way, light may enter the interior of the optical path folding element 104 from the first surface 1041, and after being reflected by the second surface 1042, it may be emitted from the third surface 1043. At this time, the second surface 1042 of the optical path folding element 104 may constitute the reflection surface 102 of the first optical element 1b. The third surface 1043 of the optical path folding element 104 may constitute the exit surface 103 of the first optical element 1b.
[0134] For example, the cross section of the light path folding element 104 may be an isosceles triangle, that is, the angle between the second surface 1042 and the first surface 1041 may be 45°, and the angle between the second surface 1042 and the third surface 1043 may also be 45°. At this time, after the light is reflected by the second surface 1042, the deflection angle of the light may be 90° (e.g. Figure 6 In other embodiments, the angle between the second surface 1042 and the first surface 1041 may be other angles, which is not specifically limited in the present application.
[0135] Exemplarily, the first lens 105 can be located on the light incident side of the optical path folding element 104. The first lens 105 can be fixedly connected to the first surface 1041 of the optical path folding element 104 by bonding or the like. The first lens 105 can be a lens with positive optical power. In this way, the first lens 105 can have a focusing effect, and the first lens 105 can allow as much external light as possible to enter the optical path folding element 104, thereby increasing the amount of light entering the entire first optical element 1b, which is beneficial to increasing the amount of light entering the subsequent focusing component 2.
[0136] In some embodiments, the first optical element 1b may further include a second lens 106. The second lens 106 may be a lens with negative optical power. The second lens 106 may be located on the light-emitting side of the optical path folding element 104. The second lens 106 may be fixedly connected to the third surface 1043 of the optical path folding element 104 by bonding or the like. In this way, the second lens 106 has a light astigmatism effect, and the second lens 106 may diffuse as much light as possible emitted from the optical path folding element 104, thereby increasing the light output of the entire first optical element 1b, which is beneficial to increasing the light input of the subsequent focusing assembly 2. At this time, the exit surface of the second lens 106 may constitute the exit surface 103 of the first optical element 1b.
[0137] Figure 7a yes Figure 6 A simplified schematic diagram of the first optical element 1b is shown. Figure 7b yes Figure 7a The structure shown is a schematic diagram of the structure from another perspective. It should be noted that Figure 7a The first optical element 1b in the figure only illustrates the light path folding element 104 and the first lens 105, and the light path folding element 104 only illustrates the second surface 1042 (ie, the reflective surface 102 of the first optical element 1b).
[0138] like Figure 7a and Figure 7bAs shown, the first optical element 1b can rotate around the first axis R1 (i.e., nodding motion). The plane where the light input axis T1 and the light output axis T2 are located is the reference plane M0. The first axis R1 can be perpendicular to the light input axis T1, and also perpendicular to the light output axis T2, that is, the first axis R1 can be perpendicular to the reference plane M0. The intersection of the light output axis T2 and the reflective surface 102 is the first intersection G1. The straight line L0 intersects with the edge line of the first lens 105 close to the focusing assembly 2, and is parallel to the light input axis T1. The straight line L0 intersects with the light output axis T2 at the second intersection G2. Exemplarily, the straight line L0 can coincide with the exit surface 103, that is, the intersection of the light output axis T2 and the exit surface 103 is the second intersection G2. The intersection of the light input axis T1 and the incident surface 101 is the third intersection G3. The intersection of the straight line L0 and the incident surface 101 is the fourth intersection G4. At this time, the first intersection G1, the second intersection G2, the third intersection G3 and the fourth intersection G4 are all on the reference plane M0. It should be understood that the first axis R1 and the light input axis T1 can be perpendicular to each other and can be completely perpendicular or approximately perpendicular, for example, the deviation is within 1°. The first axis R1 and the light output axis T2 are also perpendicular to each other and are also applicable to the above definition, which will not be repeated here.
[0139] Exemplarily, the projection point of the first axis R1 on the reference plane M0 is the first point. The first point may be located in the area defined by the straight line L1, the straight line L2, and the straight line L3. Wherein, the straight line L1 and the straight line L2 are both parallel to the light-emitting axis T2. The straight line L1 is located on the side of the light-emitting axis T2 close to the first lens 105. The straight line L2 is located on the side of the light-emitting axis T2 facing away from the first lens 105. The straight line L1 intersects the reflective surface 102 at point k1. The straight line L2 intersects the reflective surface at point k2. The distances from the straight line k1 and the straight line k2 to the light-emitting axis T2 are both 3 mm. The straight line L3 is parallel to the light-incoming axis T1. The distance between the straight line L3 and the light-incoming axis T1 is 20 mm.
[0140] It should be noted that the area defined by the straight line L1, the straight line L2 and the straight line L3 includes the area enclosed by the straight line L1, the straight line L2 and the straight line L3 and the boundaries where the straight line L1, the straight line L2 and the straight line L3 are located. In other words, the first point can be located on the image side of the reflective surface 102, and the distance between the first point and the light-emitting axis T2 can be less than or equal to 3 mm. The distance between the first point and the second intersection G2 in the X-axis direction can be less than or equal to 20 mm. In this embodiment, the first axis R1 can pass through the second intersection G2, that is, the first axis R1 can be located on the exit surface 103 of the first optical element 1b.
[0141] Figure 7c It is a simplified schematic diagram of the first optical element 1 b of the anti-shake assembly 1 rotating around the first axis R1 to perform anti-shake in some implementation modes. Figure 7d yes Figure 7aThe simplified schematic diagram of the first optical element 1b rotating around the first axis R1 for anti-shake is shown. It should be noted that: Figure 7c and Figure 7d The diagrams on the left side of the middle are schematic diagrams when the first optical element 1b is shaking and the anti-shake is not turned on, and the diagrams on the right side are schematic diagrams when the first optical element 1b is shaking and the anti-shake is turned on.
[0142] like Figure 7a , Figure 7c as well as Figure 7d As shown, when the electronic device 1000 shakes in a direction parallel to the reference plane M0 and the anti-shake function of the driving motor 1a is not turned on, the focus of the first optical element 1b is the first original focus P0. It should be understood that the light emitted by the first optical element 1b will produce multiple focuses, that is, the driving motor 1a has multiple first original focuses P0 when the anti-shake function is not turned on, and only one of the first original focuses P0 is shown here. When the electronic device 1000 shakes in a direction parallel to the reference plane M0 and the anti-shake function of the driving motor 1a is turned on, the driving motor 1a can drive the first optical element 1b to rotate around the first axis R1 to compensate for the image drift on the image plane caused by the shaking of the electronic device 1000, so as to achieve anti-shake.
[0143] It is understandable that, in some embodiments, the first axis R1' is located on the reflective surface 102 of the first optical element 1b, or on the side of the reflective surface 102 facing away from the exit surface 103. However, after the first optical element 1b rotates around the first axis R1' for anti-shake, the first focus P1' generated by the first optical element 1b has a larger offset than the first original focus P0, which causes a significant decrease in the modulation transfer function (MTF) of the camera module 100 as a whole, affecting the imaging quality.
[0144] In this embodiment, the first axis R1 may be located on the side of the reflective surface 102 facing the emission surface 103, that is, on the image side of the reflective surface 102 (at Figure 7a In this way, the first axis R1 is located on the side of the reflective surface 102 of the first optical element 1b facing the exit surface 103, so that after the first optical element 1b rotates around the first axis R1 for anti-shake, the first focus P1 generated by the first optical element 1b has a smaller offset than the first original focus P0, which is beneficial to improving the anti-shake accuracy of the camera module 100, while reducing the influence of the focus offset on the modulation transfer function, which is beneficial to improving the imaging quality.
[0145] In addition, the first axis R1 in this embodiment may pass through the second intersection G2, that is, the first axis R1 may be located on the exit surface 103 of the first optical element 1b. In this way, the focus offset caused by the rotation of the first optical element 1b around the first axis R1 is smaller, which is conducive to further reducing the influence of the focus offset on the modulation transfer function, so as to further improve the imaging quality.
[0146] Figure 8 yes Figure 7a A simplified schematic diagram of the first optical element 1b is shown. Figure 9a It is a simplified schematic diagram of the first optical element 1b of the anti-shake assembly 1 rotating around the second axis R2 for anti-shake in some implementation modes. Figure 9b yes Figure 8 The simplified schematic diagram of the first optical element 1b rotating around the second axis R2 for anti-shake is shown. Figure 8 The first optical element 1b in the figure only illustrates the light path folding element 104 and the first lens 105, and the light path folding element 104 only illustrates the second surface 1042 (ie, the reflective surface 102 of the first optical element 1b). Figure 9a and Figure 9b The diagrams on the left side of the middle are schematic diagrams when the first optical element 1b is shaking and the anti-shake is not turned on, and the diagrams on the right side are schematic diagrams when the first optical element 1b is shaking and the anti-shake is turned on.
[0147] like Figures 8 to 9b As shown, the first optical element 1b can rotate around the second axis R2 (i.e., a shaking motion). Among them, the second axis R2 can be parallel to the light-emitting axis T2, that is, the second axis R2 can be parallel to the X-axis direction. The distance between the second axis R2 and the light-emitting axis T2 can be less than or equal to 3 mm, that is, the second axis R2 can be located in a cylindrical space with a radius of 3 mm and the light-emitting axis T2 as the center axis. Exemplarily, the second axis R2 can coincide with the light-emitting axis T2. It should be understood that the second axis R2 can be completely parallel to the light-emitting axis T2 or approximately parallel, for example, the deviation is within 1°. When the electronic device 1000 shakes in a direction parallel to the reference plane M0 and the first optical element 1b is not anti-shake, the exit surface M1 of the anti-shake component 1 can be parallel to the incident surface M2 of the focusing component 2. Among them, the exit surface M1 of the anti-shake component 1 is parallel to the exit surface 103 of the first optical element 1b. When the driving motor 1a turns on the anti-shake function, the driving motor 1a can drive the first optical element 1b to rotate around the second axis R2 to compensate for the image drift on the image plane caused by the shaking of the electronic device 1000, so as to achieve anti-shake.
[0148] It is understandable that in some embodiments, the second axis R2' coincides with the light input axis G1 of the first optical element 1b, that is, the second axis R2' may be parallel to the Z-axis direction. However, when the first optical element 1b rotates around the second axis R2', the exit surface M1' of the anti-shake component 1 forms an angle with the incident surface M2 of the focusing component 2, so that there is a large inclination angle between the first optical element 1b and the focusing component 2, the optical quality of the camera module 100 is greatly reduced, the imaging quality is low, and the focus offset is large, so that the overall modulation transfer function of the camera module 100 is greatly reduced, affecting the imaging quality.
[0149] In this embodiment, the second axis R2 can be parallel to the light-emitting axis T2, that is, the second axis R2 can be perpendicular to the exit surface 103 of the first optical element 1b and the incident surface M2 of the focusing assembly 2. In this way, when the first optical element 1b rotates around the second axis R2, the exit surface M1 of the anti-shake assembly 1 can always remain parallel to the light-emitting axis T2, and remain perpendicular to the incident surface M2 of the focusing assembly 2, so that the inclination angle between the first optical element 1b and the focusing assembly 2 can be effectively reduced, the anti-shake accuracy of the camera module 100 can be improved, the optical quality of the camera module 100 can be reduced, and the focus offset can be small, which is conducive to reducing the influence of the focus offset on the modulation transfer function, thereby improving the imaging quality of the camera module 100.
[0150] In addition, the distance between the second axis R2 and the light output axis T2 can be less than or equal to 3 mm, so that the second axis R2 can be set close to the light output axis T2, thereby better reducing the impact of focus offset on the modulation transfer function, which is beneficial to improving the imaging quality of the camera module 100.
[0151] Please also read Figure 2 , Figure 7a as well as Figure 8 It can be understood that, compared with the camera module that additionally sets a reflective prism between the focus component and the image sensor and controls the displacement of the image sensor to achieve optical image stabilization, the module volume is larger. The camera module 100 in this embodiment realizes optical image stabilization of the entire camera module 100 by setting a driving motor 1a to drive the first optical element 1b to rotate around the first axis R1, and / or drives the first optical element 1b to rotate around the second axis R2, so that there is no need to additionally set a prism between the focus component 2 and the image sensor 3. The module volume is small, which is conducive to realizing the miniaturization of the camera module 100.
[0152] Secondly, the first axis R1 in this embodiment is perpendicular to both the light input axis T1 and the light output axis T2 (that is, parallel to the Y-axis direction in this embodiment), and is located on the side of the reflective surface 102 of the first optical element 1b close to the exit surface 103, that is, the image side of the reflective surface 102. The second axis R2 is parallel to the light output axis T2. In this way, whether the first optical element 1b rotates around the first axis R1 or the second axis R2, the focus offset is small, and at the same time, the exit surface M1 of the anti-shake component 1 can always remain parallel to the incident surface M2 of the focusing component 2, thereby effectively improving the anti-shake accuracy of the camera module 100, reducing the influence of the focus offset and inclination angle on the overall modulation transfer function of the camera module 100, and improving the imaging quality of the camera module 100.
[0153] In other words, the camera module 100 in this embodiment performs anti-shake by controlling the first optical element 1b to rotate around the first axis R1 and / or the second axis R2, and the first axis R1 is parallel to the Y-axis direction, the second axis R2 is parallel to the X-axis direction, and the first axis R1 is located on the side of the reflective surface 102 facing the exit surface 103 (that is, the image side of the reflective surface 102), so that the focus offset of the camera module 100 is small when performing optical image stabilization, so that it can have a higher anti-shake accuracy, and the camera module 100 has better imaging quality.
[0154] The above specifically introduces the structure of the electronic device 1000, the structure of the camera module 100 and the anti-shake principle of the first optical element 1b of the camera module 100. The following will specifically introduce the structure of the driving motor 1a in the camera module 100 in conjunction with the relevant drawings.

The length direction of the drive motor 1a, that is, the length direction of the electronic device 1000, is the Y-axis direction.

The extension plate 31b may be fixedly connected to the third sub-plate 313, and bend relative to the third sub-plate 313 in a direction toward the first sub-plate 311.

Fig.15 In the figure, the frame portion 10a and the bottom portion 10b of the base 10 are schematically divided by dotted lines.
[0170] like Figures 14 to 16As shown, the main plate 31a of the circuit board 31 can be arranged around the outer peripheral side of the frame 10a and fixedly connected to the frame 10a. Among them, the first sub-plate 311, the second sub-plate 312 and the third sub-plate 313 can be fixed to the first side portion 11, the second side portion 12 and the third side portion 13 in sequence.

At least a portion of the first sub-coil 3221 can be located in the first avoidance hole 111. At least a portion of the second sub-coil 3222 can be located in the third avoidance hole 131.

At this time, the first side wall 512 , the second side wall 513 and the support portion 511 may together enclose the installation space 51 a of the first bracket 51 .
[0184] Exemplarily, the first connecting portion 515 may be located on the side of the first side wall 512 facing away from the second side wall 513, and fixedly connected to the end of the first side wall 512 away from the third side wall 514. The second connecting portion 516 may be located on the side of the second side wall 513 facing away from the first side wall 512, and fixedly connected to the end of the second side wall 513 away from the third side wall 514.

[0189] Exemplarily, the first group of magnetic parts 53 may include a first magnet 531 and a second magnet 532. Both the first magnet 531 and the second magnet 532 may be magnets with unipolar magnetization. The polarization direction of the first magnet 531 may be opposite to the polarization direction of the second magnet 532. Wherein, the polarization direction refers to the direction in which the N pole points to the S pole in the same magnet. For example, the portion of the first magnet 531 facing the first side wall 512 is the S pole, and the portion of the first magnet 531 facing away from the first side wall 512 is the N pole. The portion of the second magnet 532 facing the first side wall 512 may be the N pole. The portion of the second magnet 532 facing away from the first side wall 512 may be the S pole.

The two N poles and the two S poles may form a magnetic field together.
[0190] Exemplarily, the plurality of first balls 551 in the plurality of first support members may be disposed in the first sliding groove 5152 of the first connecting portion 515. The first sliding groove 5152 may be a "V"-shaped groove, that is, the cross-sectional shape of the first sliding groove 5152 is a "V"-shaped groove. At this time, a tight fit may be achieved between the plurality of first balls 551 and the first sliding groove 5152. Exemplarily, the size of the first balls 551 located at both ends of the first sliding groove 5152 among the plurality of first balls 551 may be slightly larger than the size of the other first balls 551 in the first sliding groove 5152. In this way, the first balls 551 with smaller sizes may increase the span between the first balls 551 located at both ends of the first sliding groove 5152, and may also prevent the plurality of first balls 551 from getting stuck when sliding in the first sliding groove 5152.
[0191] Exemplarily, the plurality of second balls 552 in the plurality of first support members may be disposed in the second sliding groove 5162 of the second connecting portion 516.

The first connection portion 515 can be rotatably connected to the first part 521 of the second bracket 52 through a plurality of first balls 551, that is, the plurality of first balls 551 can be connected between the first connection portion 515 and the wall surface of the first space 521a. At this time, the first part 521 can half surround the first connection portion 515. In this way, the structure of the first part 521 and the first connection portion 515 is more compact, which is conducive to realizing the miniaturization of the drive motor 1a.
[0203] Exemplarily, the opening of the first sliding groove 5152 of the first connecting portion 515 and the opening of the first guide groove 5214 of the first portion 521 may be arranged opposite to each other. The first sliding groove 5152 and the first guide groove 5214 may constitute the first ball groove 501 together. The first ball groove 501 may be in an arc shape. At this time, the center of the circle where the centers of the plurality of first balls 551 are located is the first rotation center O1. The first connecting portion 515 of the first bracket 51 may rotate around the first rotation center O1 relative to the first portion 521 of the second bracket 52. It should be understood that when the sizes of the plurality of first balls 551 are not exactly the same (for example, the size of the first balls 551 located at both ends of the first ball groove 501 is larger than the size of the remaining first balls 551), the center of the circle where the centers of the plurality of first balls 551 with larger sizes are located may be taken as the first rotation center O1. In some embodiments, the center of the circle where the groove wall fitting curve of the first ball groove 501 is located may also be taken as the first rotation center O1.
[0204] Exemplarily, the second connection portion 516 of the first bracket 51 may be installed in the second space 522a of the second portion 522. The second connection portion 516 may be rotatably connected to the second portion 522 of the second bracket 52 via a plurality of second balls 552.

The second sliding groove 5162 and the second guide groove 5224 can together form the second ball groove 502. The second ball groove 502 can be in an arc shape. At this time, the center of the circle where the centers of the plurality of second balls 552 are located constitutes the second rotation center O2. The second connecting portion 516 of the first bracket 51 can rotate around the second rotation center O2 relative to the second portion 522 of the second bracket 52.
[0206] Exemplarily, the straight line where the first rotation center O1 and the second rotation center O2 are located may coincide with the first axis R1. The first axis R1 may be parallel to the Y-axis direction. The first bracket 51 may rotate around the first axis R1 relative to the second bracket 52. Exemplarily, the first axis R1 may pass through the first connecting portion 515 and the second connecting portion 516. In some embodiments, the first axis R1 may not pass through the first connecting portion 515 and the second connecting portion 516. The first axis R1 may also be located on the side of the first connecting portion 515 and the second connecting portion 516 that is away from the mounting inclined surface 511a.
[0207] Exemplarily, one of the first guide groove 5214 and the second guide groove 5224 may be a "V"-shaped groove. In this way, on the one hand, one of the first guide groove 5214 and the second guide groove 5224 is a "V"-shaped groove, which can automatically correct the relative position of the actual first rotation center N1 and the theoretical first rotation center N1, so that the movement of the first bracket 51 rotating relative to the second bracket 52 can be smoother; on the other hand, it can also avoid that the first guide groove 5214 and the second guide groove 5224 are both "V"-shaped grooves, causing the first bracket 51 to get stuck when rotating relative to the second bracket 52. In other embodiments, one of the first sliding groove 5152 and the second sliding groove 5162 of the first bracket 51 can also be a "V"-shaped groove.

[0211] like Figure 32 to Figure 34As shown, the second bracket 52 can be located on a side of the base 10 close to the light exit hole 20b of the housing 20. The second bracket 52 can be rotatably connected to the base 10 through a plurality of third balls 561. Among them, the opening of the third guide groove 5215 of the second bracket 52 can be arranged opposite to the opening of the first slide groove 112 of the base 10. The third guide groove 5215 can form a third ball groove 503 together with the first slide groove 112. The opening of the fourth guide groove 5216 of the second bracket 52 can be arranged opposite to the opening of the second slide groove 113 of the base 10. The fourth guide groove 5216 can form a fourth ball groove 504 together with the second slide groove 113. The opening of the fifth guide groove 5225 of the second bracket 52 can be arranged opposite to the opening of the third slide groove 132 of the base 10. The fifth guide groove 5225 can form a fifth ball groove 505 together with the third slide groove 132. The opening of the sixth guide groove 5226 of the second bracket 52 can be arranged opposite to the opening of the fourth slide groove 133 of the base 10. The sixth guide groove 5226 can form a sixth ball groove 506 together with the fourth slide groove 133. The four third balls 561 can be located in the third ball groove 503, the fourth ball groove 504, the fifth ball groove 505 and the sixth ball groove 506 in a one-to-one correspondence.
[0212] Among them, the first part 521 of the second bracket 52 can be rotatably connected to the first side portion 11 of the base 10 through part of the third balls 561. The second part 522 of the second bracket 52 can be rotatably connected to the third side portion 13 of the base 10 through another part of the third balls 561. The centers of the plurality of third balls 561 can be located on the same plane. The center of the circle where the centers of the plurality of third balls 561 are located is the third rotation center O3, that is, the center of the second group of support members 56. The second axis R2 can vertically pass through the plane where the centers of the plurality of third balls 561 are located. The second axis R2 can also pass through the third rotation center O3. At this time, the second bracket 52 can rotate around the second axis R2 relative to the base 10. The third rotation center O3 can be located on the side of the mounting bevel 511a of the first bracket 51 close to the light exit hole 20b, that is, the mounting side 51b of the first bracket 51. The second axis R2 can pass through the mounting bevel 511a and be parallel to the second direction (that is, the X-axis direction in this embodiment).
[0213] Exemplarily, two of the third guide groove 5215, the fourth guide groove 5216, the fifth guide groove 5225 and the sixth guide groove 5226 may be "V"-shaped grooves. In this way, on the one hand, two of the third guide groove 5215, the fourth guide groove 5216, the fifth guide groove 5225 and the sixth guide groove 5226 are "V"-shaped grooves, which can automatically correct the relative position of the actual third rotation center O3 and the theoretical third rotation center O3, so that the movement of the second bracket 52 relative to the base 10 can be smoother; on the other hand, it can also avoid that the third guide groove 5215, the fourth guide groove 5216, the fifth guide groove 5225 and the sixth guide groove 5226 are all "V"-shaped grooves or three of them are "V"-shaped grooves, which causes the second bracket 52 to get stuck when rotating relative to the base 10. In other embodiments, two of the first slide groove 112, the second slide groove 113, the third slide groove 132 and the fourth slide groove 133 of the first bracket 51 may also be "V"-shaped grooves. At least two of the third guide groove 5215 , the fourth guide groove 5216 , the fifth guide groove 5225 and the sixth guide groove 5226 of the second bracket 52 are “V”-shaped grooves.
[0214] In some embodiments, the middle portion 5212 of the first portion 521 may be located in the first avoidance groove 114 of the first side portion 11. The middle portion 5222 of the second portion 522 may be located in the second avoidance groove 134 of the third side portion 13. In this way, the first side portion 11 of the base 10 may semi-surround the first portion 521 of the second bracket 52. The third side portion 13 of the base 10 may semi-surround the second portion 522 of the second bracket 52. The second bracket 52 may utilize the length dimension of the base 10, and the arrangement of the second bracket 52 and the base 10 is more compact, which is conducive to realizing the miniaturization of the drive motor 1a.
[0215] like Fig.31a , Fig.32 and Fig.33 As shown, the magnetic attraction component 40 can generate a magnetic attraction force along the X-axis direction with the first group of magnetic components 53, thereby providing pre-pressure for the mover 50, so that the multiple first balls 551 and the second balls 552 can maintain contact with the first bracket 51 and the second bracket 52, and at the same time, the multiple third balls 561 can maintain contact with the second bracket 52 and the base 10.
[0216] Fig.35a yes Figure 3 The illustrated schematic diagram is a cross-sectional structural diagram of an embodiment of the anti-shake assembly 1 cut along B1 - B1 . Fig.35b yes Figure 3 The illustrated diagram is a cross-sectional structural diagram of an embodiment of the anti-shake assembly 1 cut along B2-B2.
[0217] like Fig.35a and Fig.35b As shown, the first optical element 1b can be installed in the installation space 51a of the first bracket 51. Exemplarily, the first optical element 1b can be fixedly connected to the first side wall 512 and the second side wall 513 of the first bracket 51 by bonding or the like. The reflective surface 102 of the first optical element 1b can face the mounting bevel 511a of the first bracket 51. It should be noted that when the first optical element 1b is installed in the first bracket 51, and the reflective surface 102 of the first optical element 1b is directly opposite to the mounting bevel 511a, the reflective surface of the first optical element 1b and the mounting bevel 511a can fit together, or there is a small gap. The small gap can be formed by an air gap or the thickness of a fixing member (such as a glue layer, etc.). At this time, the small gap between the reflective surface 102 and the mounting bevel 511a can be ignored, and the reflective surface 102 is regarded as coinciding with the mounting bevel 511a. That is, the first axis R1 can be located on the side of the reflective surface 102 close to the light exit hole 20b.
[0218] Exemplarily, the light input axis T1 of the first optical element 1b may pass through the light input hole 20a and the mounting bevel 511a. The light input axis T1 may be parallel to the first direction (i.e., the Z-axis direction in this embodiment). The light output axis T2 of the first optical element 1b may pass through the mounting bevel 511a and the light output hole 20b. The light output axis T2 may be parallel to the second direction (i.e., the X-axis direction in this embodiment). The first axis R1 may be perpendicular to the plane where the light input axis T1 and the light output axis T2 are located. The second axis R2 may coincide with the light output axis T2.
[0219] For example, the distance between the first axis R1 and the installation inclined surface 511 a may be greater than 0.01 mm. In some embodiments, the distance between the first axis R1 and the installation inclined surface 511 a may be greater than or equal to 5 mm.
[0220] Exemplarily, the center of gravity of the mover 50 and the first optical element 1b as a whole can be located on the side of the mounting bevel 511a of the mover 50 close to the light exit hole 20b, that is, the mounting side 51b of the first bracket 51. The distance between the third rotation center O3 and the center of gravity of the mover 50 and the first optical element 1b as a whole can be less than or equal to 0.3 mm. It should be noted that the center of gravity of the mover 50 and the first optical element 1b as a whole can also be approximately regarded as the center of gravity of the first bracket 51, the second bracket 52 and the first optical element 1b of the mover 50 as a whole.
[0221] For example, the first axis R1 may intersect with the second axis R2. In some embodiments, the first axis R1 and the second axis R2 may both pass through the third rotation center O3 and overlap. In some other embodiments, the first axis R1 may not intersect with the second axis R2. This application does not limit this.
[0222] When a signal is applied to the first drive coil 321, the first group of magnetic parts 53 can cooperate with the first drive coil 321 to generate a driving force along the Z-axis direction, so as to drive the first bracket 51 to rotate relative to the second bracket 52 around the first axis R1, that is, the first bracket 51 rotates relative to the stator around the first axis R1. At this time, the first group of magnetic parts 53 and the first drive coil 321 can together constitute the first driving mechanism of the drive motor 1a. The second sensor 332 can cooperate with the first group of magnetic parts 53 to detect the magnetic field strength of the first group of magnetic parts 53 at different angles of rotation of the first bracket 51 around the first axis R1, so as to detect the angle of rotation of the first bracket 51 around the first axis R1. In other words, the first optical element 1b can rotate relative to the stator around the first axis R1 under the action of the mover 50, thereby achieving anti-shake.
[0223] When a signal is applied to the second drive coil 322, the first sub-magnetic member 541 of the second group of magnetic members 54 can cooperate with the first sub-coil 3221 of the second drive coil 322 to generate a first driving force along the Z-axis direction. The second sub-magnetic member 542 of the second group of magnetic members 54 can cooperate with the second sub-coil 3222 of the second drive coil 322 to generate a second driving force along the Z-axis direction. The direction of the first driving force is opposite to the direction of the second driving force, so that the first bracket 51 can drive the second bracket 52 to rotate relative to the base 10 around the second axis R2, that is, the first bracket 51 can drive the second bracket 52 to rotate relative to the stator around the second axis R2. At this time, the second group of magnetic members 54 and the second drive coil 322 can jointly constitute the second driving mechanism of the drive motor 1a. The first sensor 331 can cooperate with the first sub-magnetic member 541, and the third sensor 333 can cooperate with the second sub-magnetic member 542 to jointly detect the magnetic field strength when the first bracket 51 rotates around the second axis R2 at different angles, so as to detect the angle of rotation of the first bracket 51 around the second axis R2. In other words, the first optical element 1 b can rotate relative to the stator around the second axis R2 under the action of the mover 50 , thereby achieving anti-shake.
[0224] It can be understood that compared with some driving motors, the mover drives the first optical element to rotate relative to the stator around the first axis, and rotates around the second axis to realize the optical image stabilization function. Among them, the first axis is parallel to the Y-axis direction. The first axis is located on the mounting bevel of the mover, or on the side of the mounting bevel facing away from the light exit hole. The second axis is parallel to the Z-axis direction. This makes the focus offset larger when the driving motor drives the first optical element to rotate around the first axis and / or around the second axis for optical image stabilization, which makes the modulation transfer function of the entire camera module drop significantly, the anti-shake accuracy is low, and the imaging quality is affected. The first axis R1 of the driving motor 1a in this embodiment is located on the side of the mounting bevel 511a close to the light exit hole 20b, that is, the mounting side 51b of the mounting bevel 511a. The first axis R1 is parallel to the Y-axis direction. In this way, when the mover 50 of the driving motor 1a drives the first optical element 1b to rotate around the first axis R1, the focus offset is small, so that the influence of the focus offset on the modulation transfer function can be effectively reduced, which is beneficial to improving the anti-shake accuracy of the entire camera module 100 and improving the imaging quality. At the same time, the mover 50 drives the first optical element 1b to rotate around the second axis R2 relative to the stator, and the second axis R2 is parallel to the X-axis direction. In this way, when the mover 50 of the driving motor 1a drives the first optical element 1b to rotate around the second axis R2, the exit surface of the anti-shake component 1 can always remain perpendicular to the light output axis T2, so that the inclination angle between the anti-shake component 1 and the focusing component 2 can be effectively reduced, and the focus offset is reduced, which is beneficial to improving the anti-shake accuracy of the entire camera module 100. The optical quality of the camera module 100 is high, which is beneficial to improving the imaging quality.
[0225] In other words, the driving motor 1a in this embodiment can effectively improve the overall anti-shake accuracy of the driving motor 1a and reduce the impact on the modulation transfer function by setting the first axis R1 parallel to the Y-axis direction and the second axis R2 parallel to the X-axis direction, and the first axis R1 is located on the installation side 51b of the installation slope 511a of the mover 50, thereby improving the imaging quality of the camera module 100.
[0226] Secondly, when the mover 50 of the driving motor 1a in this embodiment drives the stator to rotate around the second axis R2, the third rotation center O3 is located on the mounting side 51b of the mounting slope 511a of the mover 50, so that the third rotation center O3 can be closer to the center of gravity of the mover 50 and the first optical element 1b as a whole. In this way, on the one hand, the anti-interference ability of the driving motor 1a when rotating around the second axis R2 for anti-shake can be effectively enhanced; on the other hand, the power consumption of the driving motor 1a can also be reduced, which is conducive to extending the battery life of the electronic device 1000 and improving the user experience. Among them, the distance between the third rotation center O3 and the center of gravity of the mover 50 and the first optical element 1b as a whole can be less than or equal to 0.03 mm.
[0227] In addition, compared to the driving motor in which the first axis is parallel to the Y-axis direction and the first axis is located on the mounting bevel of the mover, or on the side of the mounting bevel facing away from the light exit hole, the first axis R1 of the driving motor 1a in this embodiment is located on the mounting side 51b of the mounting bevel 511a, thereby increasing the distance between the first group of magnetic parts 53 and the first axis R1, that is, increasing the driving force arm when the first group of magnetic parts 53 drives the first bracket 51 to rotate relative to the second bracket 52 around the first axis R1. In this way, under the condition that the total weight of the mover 50 and the first optical element 1b is the same, the driving motor 1a of this embodiment can generate a greater thrust for anti-shake and achieve large-angle anti-shake. Under the condition that the anti-shake angle is the same, the mover 50 of the driving motor 1a of this embodiment can bear the heavier first optical element 1b, which is beneficial to improving the optical quality of the entire camera module 100.
[0228] In addition, multiple groups of magnetic components of the driving motor 1a in this embodiment (i.e., the first group of magnetic components 53 and the second group of magnetic components 54 in this embodiment) are all arranged on the first bracket 51, so that integrated transmission can be achieved, which is beneficial to improving the smoothness of the operation of the driving motor 1a during anti-shake performance.
[0229] In some embodiments, the end of the third side wall 514 of the first bracket 51 away from the light inlet hole 20a may be provided with an anti-collision protrusion 5142 ( Fig.22a and Figure 22b The anti-collision protrusion 5142 is also shown from another perspective. The second side portion 12 of the base 10 may be provided with a limiting hole 122 ( Fig.14 The limiting hole 122 is also shown from another perspective. At least a portion of the anti-collision protrusion 5142 of the first bracket 51 can be located in the limiting hole 122 of the base 10. In this way, when the first bracket 51 rotates relative to the base 10 around the first axis R1, the anti-collision protrusion 5142 can cooperate with the limiting hole 122, thereby effectively preventing the first bracket 51 from rotating relative to the base 10 around the first axis R1 at an excessively large angle, causing the first optical element 1b to collide with the stator of the driving motor 1a and be damaged, which is beneficial to extending the service life of the camera module 100.
[0230] In other embodiments, Fig.36a and Fig.36bAs shown, the extension portion 222 of the base plate 22 may be provided with a first protrusion 2221 and a second protrusion 2222. The first protrusion 2221 may be provided toward the first side wall 512 of the first bracket 51. The second protrusion 2222 may be provided toward the second side wall 513 of the first bracket 51. The first side wall 512 of the first bracket 51 may be provided with a first limiting groove 512a. At least a portion of the first protrusion 2221 may be located in the first limiting groove 512a. The second side wall 513 of the first bracket 51 may be provided with a second limiting groove 513a. At least a portion of the second protrusion 2222 may be located in the second limiting groove 513a. In this way, when the first bracket 51 is moved relative to the stator around the second axis R2 (please refer to FIG. 2 ) under the action of the second bracket 52 Fig.35a When the camera module 100 is rotated (as shown in the figure), the first protrusion 2221 can cooperate with the first limiting groove 512a, and the second protrusion 2222 can cooperate with the second limiting groove 513a, thereby effectively preventing the first bracket 51 from rotating too much relative to the stator around the second axis R2, causing the first optical element 1b to collide with the stator of the driving motor 1a and be damaged, which is beneficial to extending the service life of the camera module 100.
[0231] Fig.37 yes Fig.10 The shown schematic diagram is a cross-sectional structure of a drive motor 1a in another embodiment cut along DD. Fig.38 yes Fig.10 The shown schematic cross-sectional structure diagram of the drive motor 1a in another embodiment is cut along CC.
[0232] like Fig.37 and Fig.38 As shown, the structure of the drive motor 1a in this embodiment is similar to Fig.10The structure of the driving motor 1a shown is substantially the same, and the same parts are not repeated. The difference is that the first group of magnetic parts 53 of the driving motor 1a in this embodiment can also include a third magnet 533. The third magnet 533 can be located between the first magnet 531 and the second magnet 532. The first magnet 531, the third magnet 533 and the second magnet 532 can be arranged in sequence along the Z-axis direction. The third magnet 533 can be a magnet with a single pole magnetization. The polarization direction of the third magnet 533 can be perpendicular to the polarization direction of the first magnet 531. For example, the portion of the first magnet 531 facing the first side wall 512 is the S pole, and the portion of the first magnet 531 facing away from the first side wall 512 is the N pole. The portion of the second magnet 532 facing the first side wall 512 can be the S pole. The portion of the second magnet 532 facing away from the first side wall 512 can be the N pole. The portion of the third magnet 533 facing the first magnet 531 can be the N pole. The portion of the third magnet 533 facing the second magnet 532 can be the S pole. At this time, the plurality of magnets of the first group of magnetic members 53 (ie, the first magnet 531 , the second magnet 532 , and the third magnet 533 in this embodiment) may form a Halbach array.
[0233] It can be understood that the first group of magnetic members 53 in this embodiment adopts a Halbach array to set a plurality of magnets. When the overall size of the first group of magnetic members 53 is the same, the driving force generated by the first group of magnetic members 53 in this embodiment using the Halbach array and the first driving coil 321 is greater. In this way, under the condition that the total weight of the mover 50 and the first optical element 1b is the same, the mover 50 in this embodiment can drive the first optical element 1b to rotate around the first axis R1 (please refer to Fig.35a ) can be rotated to a larger angle to achieve large-angle anti-shake. Under the condition of the same rotation angle, the mover 50 in this embodiment can bear the heavier first optical element 1b, which is beneficial to improving the optical quality of the entire camera module 100.
[0234] In some embodiments, the first sub-magnetic member 541 and the second sub-magnetic member 542 of the second group of magnetic members 54 can also be provided with a plurality of magnets using a Halbach array. The magnetic field direction of the first sub-magnetic member 541 can be opposite to the magnetic field direction of the second sub-magnetic member 542. The structures of the first sub-magnetic member 541 and the second sub-magnetic member 542 are substantially the same as those of the first group of magnetic members 53, and the same parts are not repeated here.
[0235] In some embodiments, the first group of magnetic parts 53 can also cooperate with the first drive coil 321 to generate a driving force parallel to the Y-axis direction, so that the first bracket 51 can be driven to drive the second bracket 52 to rotate relative to the base 10 around the second axis R2. At this time, the first group of magnetic parts 53 and the first drive coil 321 can jointly constitute the second drive mechanism of the drive motor 1a. The first sub-magnetic part 541 of the second group of magnetic parts 54 can also cooperate with the first sub-coil 3221 of the second drive coil 322 to generate a first driving force along the Z-axis direction. The second sub-magnetic part 542 of the second group of magnetic parts 54 can also cooperate with the second sub-coil 3222 of the second drive coil 322 to generate a second driving force along the Z-axis direction. Among them, the direction of the first driving force is the same as the direction of the second driving force. In this way, the first sub-magnetic part 541 and the second sub-magnetic part 542 of the second group of magnetic parts 54 can respectively cooperate with the first sub-coil 3221 and the second sub-coil 3222 to jointly drive the first bracket 51 to rotate relative to the second bracket 52 around the first axis R1. At this time, the second group of magnetic components 54 and the second driving coil 322 can together constitute the first driving mechanism of the driving motor 1 a.
[0236] In other embodiments, the first group of magnetic components 53 and the first drive coil 321 can also be arranged on the side of the first bracket 51 facing away from the light inlet 20a. The first group of magnetic components 53 can generate a driving force along the X-axis direction with the first drive coil 321, thereby driving the first bracket 51 to rotate around the first axis R1 relative to the second bracket 52. Alternatively, the positions of the first group of magnetic components 53 and the first drive coil 321 can be kept unchanged, and a fourth group of magnetic components and a third drive coil can be arranged on the side of the first bracket 51 facing away from the light inlet 20a. The fourth group of magnetic components can cooperate with the third drive coil to generate a driving force along the X-axis direction. In this way, the first group of magnetic components 53 and the fourth group of magnetic components can cooperate with the first drive coil 321 and the third drive coil respectively to jointly drive the first bracket 51 to rotate around the first axis R1 relative to the second bracket 52, which is conducive to increasing the driving force for the first bracket 51 to rotate relative to the second bracket 52 and realizing large-angle anti-shake.
[0237] Fig.39 yes Figure 3 The illustrated schematic diagram is a cross-sectional structure diagram of another embodiment of the anti-shake assembly 1 cut along B1 - B1 . Fig.40 yes Fig.39 A schematic diagram of a partial exploded structure of the anti-shake component 1 is shown.
[0238] like Fig.39 and Fig.40 As shown, the structure of the anti-shake component 1 in this embodiment is similar to Figure 3The structures of the anti-shake assembly 1 shown are roughly the same, and the same parts will not be repeated. The differences between the two will be mainly introduced below. The optical path folding element 104 of the anti-shake assembly 1 in this embodiment can be a reflective plane mirror. The reflective plane mirror may include a reflective surface 1044 and a mounting surface 1045 that are arranged opposite to each other. The reflective surface 1044 of the reflective plane mirror may face the light inlet 20a and the light outlet 20b. The mounting surface 1045 of the optical path folding element 104 may face the mounting bevel 511a of the first bracket 51. The mounting surface 1045 of the optical path folding element 104 may be fixedly connected to the mounting bevel 511a of the first bracket 51. The reflective surface 1044 of the optical path folding element 104 may be set at an angle with the surface of the first lens 105 facing the optical path folding element 104. For example, the reflective surface 1044 may be at an angle of 45° with the surface of the first lens 105 facing the optical path folding element 104. At this time, the reflective surface 1044 of the reflective plane mirror may constitute the reflective surface 102 of the first optical element 1b.
[0239] It can be understood that, compared with the anti-shake component whose optical path folding element is a reflective prism, the first surface, the second surface and the third surface of the reflective prism are all solid surfaces, and the transmission of light between the first surface and the third surface is all located inside the reflective prism. The refractive index inside the reflective prism is relatively high, which increases the optical path requirement of the entire camera module, the focusing path of the focusing component is relatively long, and the overall size of the module is relatively long. In this embodiment, the optical path folding element 104 is a reflective plane mirror, and the reflecting surface 1044 of the optical path folding element 104 is exposed to the air. In this way, the transmission of light between the light inlet 20a and the light outlet 20b is all located in the air. The refractive index in the air is relatively low, which is conducive to reducing the optical path requirement of the camera module 100, thereby shortening the focusing path of the focusing component 2, and is conducive to reducing the size of the entire module in the X-axis direction, realizing the miniaturization setting of the camera module 100.
[0240] In some embodiments, Figure 40 to Figure 42 As shown, Fig.41 yes Fig.40 The schematic diagram of the assembly structure of the first optical element 1b of the anti-shake assembly 1 and the optical mounting member 70 is shown. Fig.42 yes Fig.40 The illustrated schematic cross-sectional structure diagram of the assembly structure of the optical mounting member 70 of the anti-shake assembly 1b and a partial structure of the driving motor 1a in some embodiments.
[0241] Exemplarily, the driving motor 1a may further include an optical mounting component 70. The optical mounting component 70 may be a steel sheet. The strength of the optical mounting component 70 may be greater than the strength of the portion of the first bracket 51 where the mounting bevel 511a is located. At least a portion of the optical mounting component 70 may be located between the optical path folding element 104 and the mounting bevel 511a. In other words, the optical path folding element 104 may be indirectly fixed to the mounting bevel 511a through the optical mounting component 70. In this way, compared with the direct contact between the optical path folding element 104 and the mounting bevel 511a of the first bracket 51, the strength of the portion of the first bracket 51 where the mounting bevel 511a is located is lower, making the portion where the mounting bevel 511a is located susceptible to deformation due to impact or in a high temperature environment, thereby affecting the surface accuracy of the contact surface between the optical path folding element 104 and the mounting bevel 511a (that is, the mounting surface 1045 of the optical path folding element 104 in this embodiment) and reducing the optical quality. In this embodiment, the optical path folding element 104 is indirectly fixed to the mounting bevel 511a through the optical mounting member 70. The optical path folding element 104 is not in direct contact with the mounting bevel 511a, and the optical mounting member 70 has a high strength, so that the optical mounting member 70 is not easily deformed due to impact or in a high temperature environment, which is conducive to ensuring the surface accuracy of the contact surface between the optical path folding element 104 and the optical mounting member 70 (that is, the mounting surface 1045 of the optical path folding element 104 in this embodiment) and ensuring the optical quality of the optical path folding element 104. In other embodiments, the optical mounting member 70 can also be a glue layer. The optical path folding element 104 can be bonded and fixed to the mounting bevel 511a through the optical mounting member 70.
[0242] Exemplarily, the optical mounting member 70 may include a first mounting member 71 and a second mounting member 72. Among them, the first mounting member 71 may include a first limiting portion 711, a second limiting portion 712, a connecting portion 713 and a mounting portion 714. The first limiting portion 711 of the first mounting member 71 may be fixedly connected to the surface of the first bracket 51 facing away from the bottom 10b of the base 10. The second limiting portion 712 of the first mounting member 71 may be fixedly connected to the surface of the first side wall 512 of the first bracket 51 facing away from the third side wall 514. The mounting portion 714 of the first mounting member 71 may be fixedly connected to the mounting inclined surface 511a of the first bracket 51. The connecting portion 713 of the first mounting member 71 may be connected between the first limiting portion 711, the second limiting portion 712 and the mounting portion 714. It should be understood that the structure of the second mounting member 72 is substantially the same as that of the first mounting member 71, and the same parts are not repeated. The second limiting portion 712 of the second mounting member 72 may be fixedly connected to the surface of the second side wall 513 facing away from the third side wall 514. The mounting surface 1045 of the optical path folding element 104 can be fixedly connected to the surface of the mounting portion 714 of the first mounting member 71 facing away from the mounting inclined surface 511a and the surface of the mounting portion 724 of the second mounting member 72 facing away from the mounting inclined surface 511a. The first lens 105 can be fixedly connected to the first limiting portion 711 of the first mounting member 71 and the first limiting portion 721 of the second mounting member 72.
[0243] It can be understood that compared to the optical mounting member 70 which is a whole, that is, the first mounting member 71 and the second mounting member 72 are integrally formed. When the driving motor 1a is hit, the stress of the optical mounting member 70 is relatively concentrated and will be transmitted inward to the first optical element 1b, causing the first optical element 1b to be pulled, affecting the surface accuracy of the first optical element 1b and reducing the optical quality. In this embodiment, the optical mounting member 70 is configured as two independent and separately arranged first mounting members 71 and second mounting members 72. In this way, when the driving motor 1a is hit, the first mounting member 71 and the second mounting member 72 can respectively withstand stresses in different directions, thereby preventing the first optical element 1b from being pulled by stresses in different directions, thereby reducing its own surface accuracy and affecting the optical quality.
[0244] Secondly, the optical mount 70 cooperates with the first bracket 51 by setting a plurality of limit parts, which, on the one hand, increases the fixing area of the optical mount 70, the first bracket 51 and the first optical element 1b, which is beneficial to improve the structural stability between the optical mount 70, the first optical element 1b and the mover 50; on the other hand, the setting of the plurality of limit parts also facilitates the positioning and assembly between the optical mount 70, the first optical element 1b and the mover 50, which is beneficial to improve the assembly accuracy.
[0245] Exemplarily, the connection portion 713 of the first mounting member 71 can be bent in a direction away from the mounting portion 714. At this time, the connection portion 713 of the first mounting member 71 can be roughly bent into a "U" shape. The first bracket 51 can also be provided with a fourth avoidance hole 517. A portion of the connection portion 713 of the first mounting member 71 can be located in the fourth avoidance hole 517. In this way, by bending part of the first mounting member 71, the first mounting member 71 can also have the function of buffering and releasing stress, thereby effectively improving the overall structural stability of the anti-shake assembly 1. At the same time, the first bracket 51 is also provided with a fourth avoidance hole 517 for avoiding the connection portion 713 of the first mounting member 71, so that the structure between the first mounting member 71 and the first bracket 51 is more compact, which is conducive to realizing the miniaturization of the drive motor 1a.
[0246] Exemplarily, the connection portion 713 of the second mounting member 72 may be bent in a direction away from the mounting portion 714. At this time, the connection portion 713 of the second mounting member 72 may also be bent roughly into a "U" shape. The first bracket 51 may also be provided with a fifth avoidance hole 518. A portion of the connection portion 713 of the second mounting member 72 may be located in the fifth avoidance hole 518.
[0247] In some embodiments, the connection portion 713 of the first mounting member 71 may be provided with one or more through holes, so that the first mounting member 71 can better buffer and release stress.
[0248] The above text, in combination with the relevant drawings, specifically introduces an implementation mode of the mover 50 of the driving motor 1a, as well as the configuration of the driving motor 1a including the mover 50 in various anti-shake components 1. The following text will further introduce several configuration modes of the mover 50 of the driving motor 1a in combination with the relevant drawings.
[0249] The second implementation mode, the same technical contents as the first implementation mode are not repeated here: Fig.43 yes Fig. 20 The structure diagram of the mover 50 in the second embodiment is shown. Fig.44 yes Fig.43 The exploded structural diagram of the mover 50 is shown. Fig.45 yes Fig.44 The structure diagram of the first bracket 51 of the mover 50 shown in another viewing angle. Fig.46 yes Fig.44 The structure diagram of the second bracket 52 of the mover 50 shown in another viewing angle.
[0250] like Figure 43 to Figure 46As shown, the first bracket 51 in this embodiment may not be provided with the first mounting groove and the second mounting groove. The second bracket 52 may also be provided with a fourth mounting groove 5217 and a fifth mounting groove 5227. The fourth mounting groove 5217 may be provided in the middle portion 5212 of the first portion 521 of the second bracket 52. The opening of the fourth mounting groove 5217 may be formed on the surface of the middle portion 5212 of the first portion 521 facing away from the second portion 522. The fifth mounting groove 5227 may be provided in the middle portion 5222 of the second portion 522 of the second bracket 52. The opening of the fifth mounting groove 5227 may be formed on the surface of the middle portion 5222 of the second portion 522 facing away from the first portion 521. In some embodiments, the mover 50 may further include a magnetic conductive member 58. The magnetic conductive member 58 may be fixed to the third mounting groove 5141 of the first bracket 51.
[0251] Exemplarily, the mover 50 may further include a second reinforcement member 59. The second reinforcement member 59 may be a steel sheet. The second reinforcement member 59 may have magnetic conductivity. The second reinforcement member 59 may be embedded in the second bracket 52 by injection molding or the like. Part of the second reinforcement member 59 may be exposed through the fourth mounting groove 5217 and the fifth mounting groove 5227.
[0252] Fig.47 yes Fig.10 The shown schematic cross-sectional structure diagram of the drive motor 1 a in the second embodiment is cut along DD. Fig.48 yes Fig.10 The shown schematic cross-sectional structure diagram of the drive motor 1a in the second embodiment is taken along CC.
[0253] like Fig.47 and Fig.48 As shown, the first sub-magnetic member 541 and the second sub-magnetic member 542 of the second group of magnetic members 54 can be fixed to the second bracket 52, and are respectively located in the fourth mounting groove 5217 and the fifth mounting groove 5227. The first group of magnetic members 53 can be fixed to the first bracket 51, and are located in the third mounting groove 5141. At this time, the first group of magnetic members 53 can be arranged in the second direction (also the X-axis direction in this embodiment) with the mounting bevel 511a of the first bracket 51. The first sub-magnetic member 541, the mounting bevel 511a of the first bracket 51, and the second sub-magnetic member 542 can be arranged in the third direction (also the Y-axis direction in this embodiment) in sequence.
[0254] When a signal is applied to the first driving coil 321, the first group of magnetic members 53 can cooperate with the first driving coil 321 to generate a driving force along the Z-axis direction, thereby driving the first bracket 51 to rotate relative to the second bracket 52 around the first axis R1, that is, the first bracket 51 rotates relative to the stator around the first axis R1. In other words, the first optical element 1b can rotate relative to the stator around the first axis R1 under the action of the mover 50, thereby achieving anti-shake.
[0255] When a signal is applied to the second drive coil 322, the first sub-magnetic component 541 of the second group of magnetic components 54 can cooperate with the first sub-coil 3221 of the second drive coil 322 to generate a first driving force along the Z-axis direction.
