Description

Technical Field

[0001] This application relates to the field of shooting equipment technology, specifically to a motor, camera module and electronic equipment. Background Technology

[0002] With the development of technology, more and more electronic devices are equipped with periscope cameras to achieve long-range shooting. However, the image stabilization motors in current periscope cameras are prone to power fluctuations during operation, resulting in poor image stabilization and affecting image quality. Summary of the Invention

[0003] This application provides a motor, a camera module, and an electronic device. The motor includes a base, a first mover, and a second mover. The first mover carries an optical path folding element, and the second mover carries a lens assembly. The motor drives the first mover to rotate relative to the base via a magnetic drive to achieve optical image stabilization, and drives the second mover to shift relative to the base via a magnetic drive to achieve optical focusing. This application designs the magnetic pole distribution of the magnets in the magnetic drive structure that drives the first and second movers to reduce the interference of the magnetic field of the second mover on the movement of the first mover, thereby improving the stability of optical image stabilization and improving shooting quality.

[0004] In a first aspect, this application provides a motor. The motor includes: a base, a first mover, a first coil, two second coils, a second mover, and two third coils. The first mover is movably mounted on the base and is equipped with a first magnet group and two second magnet groups, which are spaced apart along a first direction. The first coil is fixed to the base and is arranged opposite to the first magnet group, forming a first driving member. The first driving member is used to drive at least a portion of the first mover to rotate relative to the base about a first axis, which is parallel to the first direction. The two second coils are fixed to the base and are arranged opposite to the two second magnet groups, forming a second driving member. The second driving member is used to drive at least a portion of the first mover to rotate relative to the base about a second axis, which intersects the first axis. The second mover is movably mounted on the base and is arranged spaced apart from the first mover along a second direction, which intersects the first direction. The second mover is equipped with two third magnet groups, which are arranged opposite to each other along the first direction. Two third coils are fixed to opposite sides of the base along a first direction and are arranged opposite to two third magnet groups, forming a third driving element. The third driving element is used to drive the second mover to move relative to the base along a second direction. Each second magnet group includes a second magnet with its magnetic poles pointing perpendicular to the second coil. The second magnets in the two second magnet groups are rotationally symmetrical about a second axis. Each third magnet group includes a third magnet, and the magnetic poles of the two third magnets arranged opposite to each other in the two third magnet groups point in the same direction and are perpendicular to the third coil.

[0005] In this application, since the center of the first magnet group is located between the two third magnet groups in the first direction, the magnetic pole orientation design of the two third magnet groups allows one of the first magnet group and the two third magnet groups to have magnetic attraction and the other to have magnetic repulsion. This makes the direction of the component of the first magnetic force perpendicular to the first axis and parallel to the second direction opposite to the direction of the component of the second magnetic force perpendicular to the first axis and parallel to the second direction. This reduces or even eliminates the magnetic interference caused by the first mover driving the optical path folding element to rotate relative to the base around the first axis, and improves the smoothness and accuracy of the motor driving the optical path folding element to rotate around the first axis.

[0006] In this application, since two second magnet groups are spaced apart along the first direction, and two third magnet groups are arranged opposite each other along the first direction, the magnetic pole pointing design of the two second and three magnet groups ensures that when there is magnetic attraction between the second and third magnet groups on one side, there is also magnetic attraction between the second and third magnet groups on the other side. Conversely, when there is magnetic repulsion between the second and third magnet groups on one side, there is also magnetic repulsion between the second and third magnet groups on the other side. Therefore, the direction of the component of the third magnetic force perpendicular to the second axis and the first direction is the same as the direction of the component of the fourth magnetic force perpendicular to the second axis and the first direction. This reduces or even eliminates the magnetic interference caused by the first mover driving the optical path folding element to rotate relative to the base around the second axis, improving the smoothness and accuracy of the motor-driven optical path folding element rotating around the second axis.

[0007] In some possible implementations, the second and third magnet groups are arranged at intervals along the second direction, which helps to reduce magnetic interference between the second and third magnet groups. This not only improves the stability of the motor driving the first mover to rotate the optical path folding element around the second axis, but also improves the stability of the motor driving the second mover to move at least part of the lens group along the second direction.

[0008] In some possible implementations, along the first direction, the projections of the second magnet group and the third magnet group partially overlap, so that the arrangement space of the third magnet group can reuse the space of the second magnet group, which is beneficial to reducing the length of the motor in the second direction.

[0009] In some possible implementations, the second axis is parallel to the second direction, that is, the motor can drive the optical path folding element to achieve head swinging motion, so that the output axis of the optical path folding element remains unchanged during the optical image stabilization process, thereby improving the quality of optical image stabilization.

[0010] In some possible implementations, the second magnet group and the second coil are arranged opposite each other along the first direction, that is, the two second magnet groups are located on both sides of the first mover along the first direction.

[0011] In some other possible implementations, the second magnet group and the second coil are arranged opposite each other along a second direction, that is, the second magnet group can be located on the back side of the first mover.

[0012] In some possible implementations, the second axis is parallel to the third direction, and the third direction intersects both the first and second directions. In other words, the first mover achieves optical image stabilization by shaking its head.

[0013] In some possible implementations, the second magnet group and the second coil are arranged opposite each other along a third direction, that is, the second magnet group is located at the bottom of the first mover.

[0014] In some other possible implementations, the second magnet group and the second coil are arranged opposite each other along a second direction, that is, the second magnet group is located on the back side of the first mover.

[0015] In some possible implementations, the first magnet group and the first coil are arranged opposite each other along the second direction, that is, the first magnet group is located on the back side of the first mover.

[0016] In some other possible implementations, the first magnet group and the first coil are arranged opposite each other along a third direction, which intersects both the first and second directions. That is, the first magnet group can be located at the bottom of the first mover.

[0017] In some possible implementations, the first mover includes: a first carrier, with a first magnet group fixed to the first carrier; a second carrier, movably mounted to the first carrier and movably mounted to the base, with two second magnet groups fixed to the second carrier; and a first support member, supported between the first carrier and the second carrier, the first support member including a first support portion and a second support portion spaced apart in a first direction, with a first shaft passing through the first support portion and the second support portion; the motor further includes: a second support member, supported between the second carrier and the base, with a second shaft passing through the second support member.

[0018] In this implementation, the first support and the second support are used to support the first carrier and the second carrier, providing rotational support for the first carrier to rotate about the first axis relative to the second carrier. This can improve the stability of the first carrier rotating about the first axis relative to the second carrier, thereby improving the stability of optical image stabilization when the motor is applied to the camera module.

[0019] In some possible implementations, the first mover further includes a first pre-compression component, which comprises a first magnetic attractor and a first magnetic component, one of which is fixed to a first carrier and the other to a second carrier. The first magnetic attractor and the first magnetic component are arranged opposite each other along a second direction. Along a third direction, the first magnetic attractor and the first magnetic component have different dimensions, with the larger one extending beyond the smaller one at both ends of the third direction, and the extensions are different. The third direction intersects both the first and second directions. Alternatively, the first magnetic attractor and the first magnetic component are arranged opposite each other along a third direction. Along the second direction, the first magnetic attractor and the first magnetic component have different dimensions, with the larger one extending beyond the smaller one at both ends of the second direction, and the extensions are different.

[0020] In this implementation, the design of the first magnetic attracting magnet and the first magnetic component provides a magnetic attraction force that brings the first carrier and the second carrier closer together. This allows the first support component to be stably supported between the first and second carriers, thereby improving the stability of the first carrier rotating relative to the second carrier around the first axis. Furthermore, during the rotation of the first carrier relative to the second carrier around the first axis, the first magnetic attracting magnet and the first magnetic component can also provide a magnetic restoring torque to the first carrier through magnetic attraction, thus facilitating the return of the first carrier to center.

[0021] In this implementation, by using the different sizes of the first magnetic magnet and the first magnetic component, with the larger one extending beyond the smaller one at both ends, it is possible to ensure that the relative area between the first magnetic magnet and the first magnetic component remains essentially unchanged during the rotation of the first carrier relative to the second carrier around the first axis, thereby reducing the sensitivity to the installation tolerances of the first magnetic magnet and the first magnetic component.

[0022] In this implementation, by using a first magnetic attracting magnet and a first magnetic component with different sizes, the larger one extends beyond the smaller one at both ends, and the extension sizes are different. This ensures that the magnetic restoring torque of the first pre-pressed component is 0 when the first carrier does not rotate relative to the second carrier, under the influence of interference from other magnets. This can prevent the first carrier from detaching from the second carrier after the motor is powered off, thus avoiding the optical path folding element from being biased.

[0023] In some possible implementations, the first magnetic magnet is fixed to the first carrier, and the first magnetic component is fixed to the second carrier. The first magnetic component is made of soft magnetic material, which can reduce magnetic interference from other magnets to the first magnetic magnet.

[0024] In some possible implementations, the first magnetic magnet and the first magnetic component are spaced apart, which helps to reduce the sensitivity of the first preload component to the installation tolerance of the first magnetic magnet and the first magnetic component, thereby helping the first preload component to provide more stable magnetic preload and magnetic restoring torque.

[0025] In some possible implementations, the motor further includes a second preload component, which comprises a second magnetic attractor and a second magnetic element. The second magnetic attractor is fixed to the base, and the second magnetic element is fixed to the second carrier. The second magnetic attractor and the second magnetic element are arranged opposite each other along a second direction, or they are arranged opposite each other along a third direction, which intersects both the first and second directions.

[0026] In this implementation, the second preload member can provide preload to magnetically attract the first mover to the second sidewall of the base, thereby ensuring the installation stability between the first mover, the second support member and the base.

[0027] In some possible implementations, the motor also includes two third magnetic components, which are fixed to the base and arranged at intervals in the first direction. The third magnetic components are located on the side of the second coil facing away from the second magnet group, and the two third magnetic components are arranged opposite to the second magnet group one by one.

[0028] In this implementation, the third magnetic component interacts with the second magnet group to generate a magnetic attraction force, thereby providing a magnetic restoring force for the first mover to rotate relative to the base around the second axis. This not only improves the stability of the first mover's rotation relative to the base around the second axis but also enhances the second mover's centering capability. Due to the design of the third magnetic component, the magnetic restoring torque required for the first mover's rotation relative to the base around the second axis does not solely rely on the second preload component. Therefore, the design of the third magnetic component reduces sensitivity to the installation tolerances of the second magnetic magnet and the second magnetic component, further contributing to the stability of the first mover's rotation relative to the base around the second axis.

[0029] The third magnetic component may have an opening to prevent the magnetic attraction of the third magnetic component to the second magnet group from being too large, thereby reducing the risk of the first mover rotating around the second axis relative to the base due to excessive magnetic attraction, and facilitating a smoother rotation of the first mover around the second axis relative to the base.

[0030] In some possible implementations, the motor also includes a first damping adhesive that elastically connects the second carrier and the base, so that the first damping adhesive can provide damping for the rotation of the first mover relative to the base about the second axis, thereby improving the stability of the first mover's rotation about the second axis relative to the base. Furthermore, the first damping adhesive can also provide a restoring torque for the rotation of the first mover relative to the base about the second axis, improving the first mover's return-to-center capability.

[0031] In some possible implementations, the first mover includes: a first carrier, with two second magnet groups fixed to the first carrier; a second carrier, movably mounted to the first carrier and movably mounted to the base, with the first magnet groups fixed to the second carrier; and a first support member, supported between the first carrier and the second carrier, with a second shaft passing through the first support member; the motor further includes: a second support member, supported between the second carrier and the base, the second support member including a third support portion and a fourth support portion spaced apart in a first direction, with the first shaft passing through the third support portion and the fourth support portion.

[0032] In this implementation, the arrangement of the first carrier, the second carrier, the first support member, and the second support member is designed so that the motor can drive the first carrier to rotate the optical path folding element relative to the base around the second axis, and can also drive the second carrier to rotate the first carrier and the optical path folding element together relative to the base around the first axis, thereby achieving optical image stabilization with two-axis rotation.

[0033] In some possible implementations, the motor includes: a base, a first mover, a first coil, two second coils, a second mover, and two third coils. The first mover is movably mounted on the base and has a first magnet group and two second magnet groups arranged at intervals along a first direction. The first coil is fixed to the base and is positioned opposite to the first magnet group, forming a first driving member. The first driving member drives at least a portion of the first mover to move relative to the base in a direction parallel to a third axis. The two second coils are fixed to the base and are positioned opposite to the two second magnet groups, forming a second driving member. The second driving member drives at least a portion of the first mover to move relative to the base in a direction parallel to a fourth axis, which intersects the third axis. The second movers are movably mounted on the base and are arranged at intervals with the first mover in a second direction, which intersects the first direction. The second movers have two third magnet groups arranged opposite to each other along the first direction. Two third coils are fixed to opposite sides of the base along a first direction and are arranged opposite to two third magnet groups, forming a third driving element. This third driving element drives the second mover to move relative to the base along a second direction. Each third magnet group includes a third magnet, and the magnetic poles of the two opposing third magnets in the two third magnet groups point in the same direction and are perpendicular to the third coils. The center line connecting the two second magnet groups has a perpendicular bisector, and each second magnet group includes a second magnet. The second magnets in the two second magnet groups are mirror-symmetrical about the perpendicular bisector.

[0034] In this application, optical image stabilization is achieved by designing a first driving member and a second driving member to drive the first mover to move relative to the base along the third and fourth axes. Through the magnetic force design between the third and second magnet groups, the forces exerted by the two third magnet groups on the two second magnet groups can cancel each other out in a direction parallel to the fourth axis, thereby reducing or even eliminating magnetic interference from the second mover to the first mover, and thus improving the smoothness of the motor in achieving optical image stabilization.

[0035] Secondly, this application provides a camera module. The camera module includes an optical path folding element, a lens group, an image sensor, and a motor as described in any of the first aspects. The optical path folding element is mounted on a first moving part, at least a portion of the lens group is mounted on a second moving part, and the image sensor is located on the side of the lens group facing away from the optical path folding element.

[0036] In this application, by designing the magnet arrangement of the motor, the magnetic interference caused by the motor driving the first mover to rotate around the first and second axes is reduced or even eliminated, thereby improving the stability of the camera module in achieving optical image stabilization, and thus enhancing the shooting stability of the camera module.

[0037] In some possible implementations, the lens group includes multiple mirror groups, with the mirror group closest to the optical path folding element being the first mirror group, which is fixed to the second mover.

[0038] In this implementation, when the second mover approaches the first mover, the torque interference of the second mover on the first mover can be basically eliminated. Therefore, by designing the first mirror group as a moving group, the third magnet group in the second mover can be closer to the first mover. This is beneficial to weaken or even eliminate the magnetic interference of the second mover on the first mover through the magnetic pole design of the magnet.

[0039] Thirdly, this application provides an electronic device. The electronic device includes an image processor and a camera module as described in any of the second aspects, wherein the image processor is communicatively connected to an image sensor.

[0040] In this application, by designing the magnet arrangement of the motor, the magnetic interference caused by the motor driving the first mover to rotate around the first and second axes is reduced or even eliminated, thereby improving the stability of the camera module in achieving optical image stabilization, thus enhancing the shooting stability of the camera module and improving the shooting experience of the electronic device.

[0048] Please refer to the following: Figure 1A and Figure 1B , Figure 1A This is a schematic diagram of the structure of the electronic device 1000 provided in some embodiments of this application; Figure 1B yes Figure 1A A partial exploded view of the electronic device 1000 shown.

[0049] In some embodiments, the electronic device 1000 can be a mobile phone, tablet personal computer, laptop computer, smart screen, personal digital assistant (PDA), camera, personal computer, laptop computer, in-vehicle equipment, wearable device, augmented reality (AR) glasses, AR helmet, virtual reality (VR) glasses, or VR helmet, or other devices with camera functions. Figure 1A In this embodiment, the electronic device 1000 is a mobile phone as an example for description. Of course, other types of electronic devices 1000 can also adopt a similar structure, which will not be described in detail below.

[0050] Understandable Figure 1A and Figure 1B The electronic device 1000 is shown only schematically, and the actual shape, size, location, and construction of these components are not subject to change. Figure 1A and Figure 1B Due to limitations, electronic device 1000 may also include, compared to Figure 1A and Figure 1B More or fewer parts.

[0051] In some embodiments, the electronic device 1000 may include a camera module 100, a screen 200, and a housing 300. The screen 200 is used to display images, videos, etc. The screen 200 may include a light-transmitting panel 2001 and a display screen 2002. The light-transmitting panel 2001 and the display screen 2002 are stacked and fixedly connected. The light-transmitting panel 2001 mainly serves to protect the display screen 2002 from dust. The material of the light-transmitting panel 2001 includes, but is not limited to, glass. The display screen 2002 may be a flexible display screen or a rigid display screen. For example, the display screen 2002 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MLED) display screen, a micro organic light-emitting diode (MOLED) display screen, a quantum dot light-emitting diode (QLED) display screen, a liquid crystal display (LCD), etc.

[0052] For example, the housing 300 is used to protect the internal electronic components of the electronic device 1000. The housing 300 may include a cover plate 3001, a frame 3002, and a camera trim 3003. The cover plate 3001 is located on the side of the display screen 2002 away from the light-transmitting panel 2001, and is stacked with the light-transmitting panel 2001 and the display screen 2002. The frame 3002 is fixed to the cover plate 3001. For example, the frame 3002 can be fixedly connected to the cover plate 3001 by adhesive. The frame 3002 may also be integrally formed with the cover plate 3001, that is, the frame 3002 and the cover plate 3001 are a single structure. The frame 3002 is located between the cover plate 3001 and the light-transmitting panel 2001. The light-transmitting panel 2001 can be fixed to the frame 3002 by adhesive. The light-transmitting panel 2001, the cover plate 3001, and the frame 3002 enclose the internal mounting space of the electronic device 1000. The internal installation space accommodates the display screen 2002. The cover plate 3001 can be made of materials such as metal, plastic, or glass. The cover plate 3001 can be a single-material panel or a panel structure composed of multiple materials and panels. The cover plate 3001 has a mounting opening 3004, and the camera decorative piece 3003 covers and is fixed to the mounting opening 3004.

[0053] For example, camera module 100 is used to capture photos / videos. For example, camera module 100 is mounted within housing 300, located within the internal mounting space of electronic device 1000. Camera module 100 can be used as a rear-facing camera. For example, the light-incident surface of camera module 100 faces camera trim 3003. Camera trim 3003 is used to protect camera module 100.

[0054] In some embodiments, the camera trim 3003 protrudes from the side of the cover plate 3001 away from the light-transmitting panel 2001. This increases the mounting space of the camera module 100 in the thickness direction of the electronic device 1000. In other embodiments, the camera trim 3003 may be flush with the cover plate 3001 or recessed into the internal mounting space of the electronic device 1000.

[0055] The camera decorative element 3003 has a light-transmitting hole 3005. The light-transmitting hole 3005 allows light from objects to enter the light-receiving surface of the camera module 100. In some other embodiments, the electronic device 1000 may not include the camera decorative element 3003. In this case, the cover plate 3001 no longer has a mounting opening 3004, but the light-transmitting hole 3005 is provided on the cover plate 3001, allowing light from objects to enter the light-receiving surface of the camera module 100.

[0056] In some embodiments, the camera module 100 can also be used as a front-facing camera. For example, the light-incident surface of the camera module 100 faces the light-transmitting panel 2001. The display screen 2002 is provided with a light-path obstruction hole. This light-path obstruction hole allows light from the scene to pass through the light-transmitting panel 2001 and then enter the light-incident surface of the camera module 100. In some embodiments, the electronic device 1000 may also include one or more other camera modules (not shown in the figures), which are not strictly limited in this application.

[0057] In some embodiments, such as Figure 1B As shown, the electronic device 1000 may further include a circuit board assembly 400 and an image processor 500. The circuit board assembly 400 and the image processor 500 are located within the internal mounting space of the electronic device 1000. The image processor 500 is fixed to and electrically connected to the circuit board assembly 400. The image processor 500 is communicatively connected to the camera module 100. The image processor 500 is used to acquire image data from the camera module 100 and process the image data. The communication connection between the camera module 100 and the image processor 500 may include data transmission via electrical connections such as wiring, or data transmission via coupling or other methods. It is understood that the camera module 100 and the image processor 500 may also achieve a communication connection through other methods capable of data transmission.

[0058] In some embodiments, the electronic device 1000 may further include an analog-to-digital converter (also known as an A / D converter, not shown in the figure). The analog-to-digital converter is connected between the camera module 100 and the image processor 500. The analog-to-digital converter is used to convert the signal generated by the camera module 100 into a digital image signal and transmit it to the image processor 500, whereby the image processor 500 processes the digital image signal and finally displays the image or video on the screen 200.

[0059] In some embodiments, the electronic device 1000 may further include a memory (not shown in the figure), which is communicatively connected to the image processor 500. The image processor 500 processes the digital image signal and then transmits the image to the memory, so that the image can be retrieved from the memory and displayed on the screen 200 at any time when it is needed to view the image later. In some embodiments, the image processor 500 may also compress the processed digital image signal before storing it in the memory to save memory space.

[0060] In some other embodiments, the electronic device 1000 may also not include the screen 200.

[0061] Understandable Figure 1A and Figure 1BThe installation position of the camera module 100 in the illustrated embodiment of the electronic device 100 is merely illustrative, and this application does not strictly limit the installation position of the camera module 100. In some other embodiments, the camera module 100 may also be installed in other locations on the electronic device 1000, such as the upper middle or upper right corner of the back of the electronic device 1000. In some other embodiments, the electronic device 1000 may include a terminal body and an auxiliary component that can rotate, move, or be detached relative to the terminal body, and the camera module 100 may also be disposed on the auxiliary component.

[0062] Please see Figure 2A and Figure 2B , Figure 2A yes Figure 1B A schematic diagram of the optical path of the camera module 100 in some embodiments of the electronic device 1000 shown; Figure 2B yes Figure 2A The diagram shows a pivot axis for image stabilization in some embodiments of the camera module 100.

[0063] Please see Figure 2A In some embodiments, the camera module 100 may include a motor 10, an optical path folding element 20, a lens group 30, and an image sensor 40. The optical path folding element 20, the lens group 30, and the image sensor 40 are arranged sequentially at intervals along the optical path direction of the camera module 100. Both the optical path folding element 20 and the lens group 30 are mounted on the motor 10. It should be noted that the optical path direction of the camera module 100 is such that light enters from the outside, is reflected by the optical path folding element 20, passes through the lens group 30, and reaches the image sensor 40. Figure 2A The diagram uses a dashed line with an arrowhead.

[0064] For ease of description, a three-dimensional coordinate system is defined in this application. The input optical axis direction of the optical path folding element 20 is defined as the third direction Z (also known as the Z-axis direction), the output optical axis direction of the optical path folding element 20 is defined as the second direction X (also known as the X-axis direction), and the direction intersecting both the third direction Z and the second direction X is defined as the first direction Y (also known as the Y-axis direction). The third direction Z, the second direction X, and the first direction Y can be mutually perpendicular. It is understood that in some other embodiments, other references may be used to define the coordinate system, which is not limited here.

[0065] For example, the optical path folding element 20 is used to fold the optical path of the received light and transmit it to the lens group 30, thereby adjusting the light incident in the third direction Z to be transmitted along the second direction X. Optical path folding, also known as optical path reversal, refers to changing the transmission path of light. For example, the optical path folding element 20 may include a prism (e.g., a right-angle prism or a triangular prism) or a reflective element such as a mirror. In some other embodiments, the optical path folding element 20 may also be referred to as an optical folding element.

[0066] The optical path folding element 20 may further include a prism and one or more lenses. The lenses may be fixedly mounted on the light-incident side and / or the light-exit side of the prism to optimize the imaging effect of the camera module. For example, a lens with positive optical power may be provided on the light-incident side of the prism, that is, a power lens may be provided on the light-incident side of the prism to achieve a large aperture design.

[0067] For example, the lens group 30 is used to transmit the light reflected by the optical path folding element 20 to the image sensor 40, thereby imaging the scene on the object side onto the image plane on the image side. Here, the object side refers to the side where the subject is located, and the image side is the side where the image of the subject is located. The lens group 30 can also perform certain processing on the light reflected by the optical path folding element 20, such as aberration correction and chromatic aberration ablation.

[0068] The lens group 30 may include at least one lens (or lens element), which may be different or the same. In this embodiment, the number of lenses and lens materials included in the lens group 30 are not specifically limited. The number of lenses can be set according to actual needs, or a combination of solid lenses (with fixed lens parameters) and / or liquid lenses (with dynamically adjustable lens parameters) can be used.

[0069] It should be noted that, Figure 2A and Figure 2B The number of lenses in the intermediate lens group 30 is only illustrative and is not limited. It is understood that in some other embodiments, the number of lenses may be more or less.

[0070] For example, the image sensor 40 is disposed on the image side of the lens group 30 and is mainly used for imaging. Specifically, the image sensor 40 has an image acquisition area (also called a photosensitive area or photosensitive surface), through which the image sensor 40 acquires the received light. The image sensor 40 is a device with photoelectric conversion function, capable of converting the light signal acquired on the image acquisition area into an electrical signal proportional to the light signal. The image sensor 40 can be a CCD image sensor 40 composed of a charge-coupled device (CCD) or a CMOS image sensor 40 composed of a complementary metal oxide semiconductor (CMOS).

[0071] In some other embodiments, the camera module 100 may further include a second optical path folding element (not shown in the figure). The second optical path folding element may be located between the lens group 30 and the image sensor 40 to fold the optical path between the lens group 30 and the image sensor 40, thereby increasing the optical path length within the camera module 100 and reducing the length dimension of the camera module 100 (i.e., the dimension in the second direction X). In addition, due to the provision of the second optical path folding element, the image sensor 40 can be laid flat or tilted, thereby reducing the thickness of the image sensor 40 in the camera module 100 (i.e., the dimension in the third direction Z), which is beneficial for achieving a thinner and lighter design of the camera module 100.

[0072] In this application, the optical path folding element 20, the lens group 30, and the image sensor 40 are arranged sequentially along the optical path direction. The imaging principle of the camera module 100 is as follows: the light entering the camera module 100 from the object side is folded by the optical path folding element 20, and the folded light is projected onto the image sensor 40 through the lens group 30 to achieve imaging of the object.

[0073] To reduce image blur caused by camera shake during shooting and improve image quality, periscope camera modules 100 generally have optical image stabilization. For periscope camera modules 100, a motor 10 is typically used to drive the optical path folding element 20 to rotate in order to compensate for camera shake.

[0074] Please see Figure 2BIn some embodiments, the optical path folding element 20 can be mounted on the motor 10. The motor 10 can drive the optical path folding element 20 to rotate around a first axis L1 and around a second axis L2, thereby achieving anti-shake compensation. That is, the motor 10 can realize the rotation of the optical path folding element 20 in two degrees of freedom, i.e., the motor 10 can control the optical path folding element 20 to rotate around two axes. In this embodiment, the motion performed by the optical path folding element 20 under the drive of the motor 10 can also be called a two-degree-of-freedom axis-shifting rotation motion. Correspondingly, the motor 10 can be called a two-axis rotary voice coil motor.

[0075] For example, the first axis L1 may be parallel to the first direction Y, and the second axis L2 may be parallel to the third direction Z or the second direction X.

[0076] It should be noted that the position of the axis through which the motor 10 drives the optical path folding element 20 to rotate can be designed to any position. The rotation of the optical path folding element 20 around the first axis L1 is also called a nodding motion. When the second axis L2 is parallel to the second direction X, the rotation of the optical path folding element 20 around the second axis L2 is also called a swaying motion. When the second axis L2 is parallel to the third direction Z, the rotation of the optical path folding element 20 around the second axis L2 is also called a head-shaking motion.

[0077] It should be noted that, Figure 2A and Figure 2B This illustration only shows some of the components included in the camera module 100. The actual shape, size, position, and structure of these components are not subject to change. Figure 2A and Figure 2B Due to limitations, camera module 100 can also include, compared to Figure 2A and Figure 2B More or fewer parts.

[0078] Next, we will introduce the magnet arrangement in motor 10.

[0079] Please refer to the following: Figures 3 to 5B , Figure 3 yes Figure 1A A schematic diagram of the camera module 100 in some embodiments of the electronic device 1000 shown; Figure 4A yes Figure 3 A partial structural diagram of the camera module 100 shown in some embodiments after being cut open along line A1-A1; Figure 4B yes Figure 3 A partial structural diagram of the camera module 100 shown in some embodiments after being cut open along line A2-A2; Figure 5A yes Figure 3 A partial structural diagram of the camera module 100 shown in some embodiments after being cut open along line BB; Figure 5B yes Figure 3The diagram shows the arrangement of the magnets of the motor 10 in the camera module 100 in some embodiments.

[0080] Please see Figure 4A In some embodiments, the motor 10 may include a base assembly 1, a first mover 2, and a second mover 3. Both the first mover 2 and the second mover 3 are movably mounted on the base assembly 1, and are spaced apart in a second direction X. The first mover 2 carries the optical path folding element 20, causing it to rotate relative to the base assembly 1 about a first axis L1 or a second axis L2, thereby achieving optical image stabilization. The second mover 3 carries at least a portion of the lens group 30, causing it to move relative to the base assembly 1 along the second direction X, thereby achieving optical focusing.

[0081] For example, the first mover 2 may be equipped with a first magnet group 231. The base assembly 1 may include a base 11 and a first coil 121. The first coil 121 is fixed to the base 11 and is arranged opposite to the first magnet group 231, forming a first driving member 4. The first driving member 4 is used to drive the first carrier 232 to drive the optical path folding element 20 to rotate relative to the base 11 around the first axis L1.

[0082] It should be noted that "the first coil 121 and the first magnet group 231 are arranged opposite each other" means that the orthographic projection of the first coil 121 in a certain direction toward the first magnet group 231 at least partially falls on the first magnet group 231. In the following text, "arranged opposite each other" means that the orthographic projection of one of them in a direction toward the other at least partially falls on the other. Furthermore, "arranged directly opposite each other" means that the orthographic projection of one of them in a direction toward the other completely falls on the other.

[0083] Please see Figure 4B For example, the first mover 2 may also be equipped with two second magnet groups 241, which are arranged at intervals along the first direction Y. The base assembly 1 may also include two second coils 122, which are fixed to the base 11 and arranged opposite to the two second magnet groups 241, forming a second driving member 5. The second driving member 5 is used to drive at least a portion of the first mover 2 to rotate relative to the base 11 about a second axis L2. The two-axis rotation of the optical path folding element 20 can be achieved through the second driving member 5 and the first driving member 4, thereby realizing optical image stabilization.

[0084] Please see Figure 5AFor example, the second mover 3 may be equipped with two third magnet groups 31, which are arranged opposite each other along the first direction Y. The base assembly 1 may also include two third coils 123, which are fixed to opposite sides of the base 11 along the first direction Y and are arranged opposite to the two third magnet groups 31, forming a third driving member 6. The third driving member 6 is used to drive the second mover 3 to move relative to the base 11 along the second direction X, thereby realizing optical focusing.

[0085] Please see Figure 4B and Figure 5B For ease of description, let's use Figure 5B Taking the perspective shown as an example, the second magnet group 241 on the left is the second magnet group 241a, and the second magnet group 241 on the right is the second magnet group 241b; the third magnet group 31 on the left is the third magnet group 31a, and the third magnet group 31 on the right is the third magnet group 31b.

[0086] In some embodiments, the third magnet group 31a has a first magnetic force on the first magnet group 231, and the third magnet group 31b has a second magnetic force on the first magnet group 231. The first magnetic force has a first component force, which is perpendicular to the first axis L1 and parallel to the second direction X (see...). Figure 5B (F11 in the text). The second magnetic force has a second component force, which is perpendicular to the first axis L1 and parallel to the second direction X (see F11 in the text). Figure 5B (F12 in the text). The first and second component forces point in opposite directions.

[0087] In this embodiment, through the above-described magnet design, the first magnetic force will generate a first torque on the first magnet group 231 rotating around the first axis L1, and the second magnetic force will generate a second torque on the first magnet group 231 rotating around the first axis L1. The direction of the first torque is opposite to the direction of the second torque, so that the first torque and the second torque at least partially cancel each other out. This reduces or even eliminates the magnetic interference of the third magnet group 31a and the third magnet group 31b on the rotation of the first magnet group 231 around the first axis L1. In other words, it reduces or even eliminates the magnetic interference of the first mover 2 driving the optical path folding element 20 to rotate relative to the base 11 around the first axis L1, and improves the smoothness and accuracy of the motor 10 driving the optical path folding element 20 to rotate around the first axis L1.

[0088] In some embodiments, the third magnet group 31a has a third magnetic force on the second magnet group 241a, and the third magnet group 31b has a fourth magnetic force on the second magnet group 241b. The third magnetic force has a third component force, which is perpendicular to the second axis L2 and perpendicular to the first direction Y (see...). Figure 5B (F21 in the text), the fourth magnetic force has a fourth component force, which is perpendicular to the second axis L2 and perpendicular to the first direction Y (see F21 in the text). Figure 5BIn F22), the third component force and the fourth component force point in the same direction.

[0089] In this embodiment, through the above-described magnet design, the third magnetic force will generate a third torque on the second magnet group 241a rotating around the second axis L2, and the fourth magnetic force will generate a fourth torque on the second magnet group 241b rotating around the second axis L2. The direction of the third torque is the same as the direction of the fourth torque, and the second magnet group 241a and the second magnet group 241b are located on both sides of the second axis L2, so that the third torque and the fourth torque at least partially cancel each other out. This reduces or even eliminates the magnetic interference of the third magnet group 31a and the third magnet group 31b on the second magnet group 241a and the second magnet group 241b. That is, it reduces or even eliminates the magnetic interference of the first mover 2 driving the optical path folding element 20 to rotate relative to the base 11 around the second axis L2, and improves the smoothness and accuracy of the motor 10 driving the optical path folding element 20 to rotate around the second axis L2.

[0090] Please see Figures 4B to 5B In some embodiments, each third magnet group 31 includes a third magnet 311, and the magnetic poles of the two third magnets 311 arranged opposite each other in the two third magnet groups 31 point in the same direction and are perpendicular to the third coil.

[0091] In this embodiment, since the center of the first magnet group 231 is located between the two third magnet groups 31 in the first direction Y, through the magnetic pole orientation design of the two third magnet groups 31, one of the first magnet group 231 and the two third magnet groups 31 exerts magnetic attraction, and the other exerts magnetic repulsion. This allows the first magnetic force to have a component perpendicular to the first axis L1 and parallel to the second direction X (see...). Figure 5B The direction of F11 in the figure is related to the component of the second magnetic force perpendicular to the first axis L1 and parallel to the second direction X (see [reference]). Figure 5B The F12 in the middle is opposite to the direction, thereby reducing or even eliminating the magnetic interference caused by the first mover 2 driving the optical path folding element 20 to rotate relative to the base 11 around the first axis L1, and improving the smoothness and accuracy of the motor 10 driving the optical path folding element 20 to rotate around the first axis L1.

[0092] For example, the magnet closest to the first magnet group 231 in the third magnet group 31 is the third magnet 311, and the magnetic poles of the third magnet 311 in the two third magnet groups 31 point in the same direction and are both perpendicular to the third coil 123.

[0093] For example, in the two third magnet groups 31, the magnets whose magnetic poles are perpendicular to the third coil 123 are all third magnets 311, and the magnetic poles of the third magnets 311 arranged opposite each other along the first direction Y have the same direction.

[0094] In some embodiments, each second magnet group 241 may include a second magnet 2411, the magnetic poles of which are perpendicular to the second coil 122. The second magnets 2411 in the two second magnet groups 241 may be rotationally symmetrical about the second axis L2. In other words, after one second magnet group 241 is rotated about the second axis L2 by a certain angle, the second magnets 2411 in the two second magnet groups 241 coincide, and the magnetic poles of the two coincident second magnets 2411 point in the same direction.

[0095] It should be noted that after a second magnet group 241 rotates around the second axis L2 by a certain angle, the second magnets 2411 in the two second magnet groups 241 overlap. However, it is not required that the two overlap completely, and deviations in size are allowed.

[0096] In this embodiment, since the two second magnet groups 241 are spaced apart in the first direction Y, and the two third magnet groups 31 are arranged opposite each other along the first direction Y, due to the magnetic pole pointing design of the two second magnet groups 241 and the two third magnet groups 31, when there is magnetic attraction between the second magnet group 241 and the third magnet group 31 on one side, there is also magnetic attraction between the second magnet group 241 and the third magnet group 31 on the other side. When there is magnetic repulsion between the second magnet group 241 and the third magnet group 31 on one side, there is also magnetic repulsion between the second magnet group 241 and the third magnet group 31 on the other side. Therefore, the component of the third magnetic force perpendicular to the second axis L2 and perpendicular to the first direction Y (see...) Figure 5B The direction of F21 in the figure is related to the component of the fourth magnetic force perpendicular to the second axis L2 and perpendicular to the first direction Y (see [reference]). Figure 5B The direction of F22 in the first moving part 2 is the same, thereby reducing or even eliminating the magnetic interference caused by the first moving part 2 driving the optical path folding element 20 to rotate relative to the base 11 around the second axis L2, and improving the smoothness and accuracy of the motor 10 driving the optical path folding element 20 to rotate around the second axis L2.

[0097] For example, with Figure 5B Taking the embodiment shown as an example, after the second magnet group 241a rotates around the second axis L2 by a certain angle, it can coincide with the second magnet group 241b, wherein the magnetic poles of the two coinciding second magnets 2411 point in the same direction.

[0098] For example, the magnetic poles of the two second magnets 2411 arranged opposite each other in the two second magnet groups 241 point in the same direction and are perpendicular to the second coil 122.

[0099] Each second magnet group 241 includes at least two second magnets 2411, and the magnetic poles of each second magnet 2411 are perpendicular to the second coil 122. The second magnets 2411 arranged opposite each other in the two second magnet groups 241 have the same magnetic pole orientation.

[0100] In the two second magnet groups 241, the magnets whose magnetic poles are perpendicular to the second coil 122 are all second magnets 2411, and the magnetic poles of the second magnets 2411 that are arranged opposite each other along the first direction Y have the same magnetic pole direction.

[0101] It should be noted that, Figure 5B The magnetic pole markings of each magnet are for illustrative purposes only. In some other embodiments, the N pole and S pole may be interchanged.

[0102] All of these need to be explained. Figure 5B The illustration uses a Hellbeck magnet group as an example, where the magnetic pole of the central magnet in each magnet group points parallel to the arrangement direction of the magnets on either side. In some other embodiments, the magnet group may not include the central magnet.

[0103] Please refer to the following: Figures 5B to 6B , Figure 6A This is a simulation diagram of the magnetic interference between the second mover 3 and the first mover 2 in some other embodiments; Figure 6B yes Figure 5B The above is a simulation diagram of the magnetic interference between the second mover 3 and the first mover 2 in the embodiment shown.

[0104] It should be noted that, Figure 6A and Figure 6B The solid line represents the torque variation with rotation angle when the first mover 2 rotates alone without the second mover 3; the dashed line represents the torque variation with rotation angle when the first mover 2 rotates when the motor 10 includes the first mover 2 and the second mover 3, and the second mover 2 is in a position close to the first mover 2; the dotted line represents the torque variation with rotation angle when the first mover 2 rotates when the motor 10 includes the first mover 2 and the second mover 3, and the second mover 2 is in a position far from the first mover 2. The difference in the vertical axis between the dashed line and the solid line represents the torque interference value of the second mover 3 on the first mover 2 when it is close to the first mover 2, and the difference in the vertical axis between the dotted line and the solid line represents the torque interference value of the second mover 3 on the first mover 2 when it is far from the first mover 2.

[0105] Please see Figure 5B and Figure 6A In some other embodiments, in the two third magnet groups 31, the magnetic poles of the magnets that are perpendicular to the third coil 123 and are arranged opposite each other have different magnetic pole orientations. In the two second magnet groups 241, the magnetic poles of the magnets that are perpendicular to the second coil 122 and are located on the same side of the second magnet group 241 have the same magnetic pole orientation. Figure 6A The simulation results are as follows: When the second mover 3 approaches the first mover 2, the difference in the vertical coordinate between the dashed line and the solid line is significant, indicating that the torque interference of the second mover 3 on the first mover 2 is relatively large.

[0106] Please refer to the following: Figure 5B and Figure 6B , Figure 6B This application Figure 5B According to the simulation results of the corresponding embodiment, it can be seen that in the embodiment of this application, when the second mover 3 is close to the first mover 2, the difference in the vertical coordinate between the dashed line and the solid line is close to 0, indicating that the torque interference of the second mover 3 on the first mover 2 is very small.

[0107] Therefore, through the magnetic pole design of the second magnet group 241 and the third magnet group 31 in the embodiments of this application, when the second mover 3 is close to the first mover 2, the magnetic interference of the third magnet group 31 in the second mover 3 on the first magnet group 231 and the second magnet group 241 in the first mover 2 can be significantly reduced, so as to reduce or even eliminate the torque interference of the second mover 3 on the first mover 2.

[0108] Please see Figure 4A For example, the lens group 30 may include a first lens group 301 and a second lens group 302, the first lens group 301 and the second lens group 302 are arranged at intervals in the second direction X, the first lens group 301 is fixed to the second mover 3, and the second lens group 302 is fixed to the base 11.

[0109] The lens group 30 may include multiple lens groups, with the first lens group 301 being the one closest to the optical path folding element 20. The motor 10 can drive the first lens group 301 to move along the second direction X to achieve focusing, thereby improving the imaging effect of the camera module 100. Specifically, the first lens group 301 can achieve focusing along the second direction X, thereby improving the sharpness of the camera module 100; alternatively, the first lens group 301 can achieve zooming along the second direction X, thereby changing the focal length of the camera module 100 to adapt to various shooting scenarios.

[0110] In this embodiment, by Figure 6B Simulation results show that when the second mover 3 approaches the first mover 2, the torque interference of the second mover 3 on the first mover 2 can be basically eliminated. Therefore, by designing the first mirror group 301 as a moving group, the third magnet group 31 in the second mover 3 can be closer to the first mover 2. This is beneficial to weaken or even eliminate the magnetic interference of the second mover 3 on the first mover 2 through the magnetic pole design of the magnet.

[0111] It should be noted that in this embodiment, the first lens group 301 can move along the second direction X to achieve focusing. In other embodiments, focusing can also be achieved by moving other lens groups along the second direction X, or by moving multiple lens groups along the second direction X, or by moving some lenses in a certain lens group along the second direction X.

[0112] Please see Figure 5BIn some embodiments, the second magnet group 241 and the third magnet group 31 can be arranged at intervals along the second direction X, which helps to reduce the magnetic interference between the second magnet group 241 and the third magnet group 31. This not only improves the stability of the motor 10 driving the first mover 2 to rotate the optical path folding element 20 around the second axis L2, but also improves the stability of the motor 10 driving the second mover 3 to move at least part of the lens group 30 along the second direction X.

[0113] For example, along the second direction X, the spacing between the second magnet group 241 and the third magnet group 31 (see [reference]). Figure 5B Within the range of d) less than or equal to 10 mm, it can not only reduce the magnetic interference between the second magnet group 241 and the third magnet group 31, but also facilitate the reduction or even elimination of the magnetic interference of the third magnet group 31 on the second magnet group 241 through the magnetic pole pointing design of the second magnet group 241 and the third magnet group 31.

[0114] For example, the value of d can be, but is not limited to, 1 mm, or 1.5 mm, or 3 mm, or 3.5 mm, or 4 mm, or 4.5 mm, or 5 mm, or 6 mm, or 7 mm, or 8 mm, or 9 mm, or 10 mm, or other values ​​less than 10 mm.

[0115] Please see Figure 4B and Figure 5B In some embodiments, the second axis L2 is parallel to the second direction X, that is, the motor 10 can drive the optical path folding element 20 to achieve head swinging motion, so that the output axis of the optical path folding element 20 remains unchanged during the optical image stabilization process, thereby improving the quality of optical image stabilization.

[0116] For example, the second magnet group 241 and the second coil 122 can be arranged opposite each other along the first direction Y. That is, the two second magnet groups 241 are located on both sides of the first mover 2 along the first direction Y.

[0117] Please see Figure 4A and Figure 5B For example, the first magnet group 231 and the first coil 121 can be arranged opposite each other along the third direction Z. That is, the first magnet group 231 is located at the bottom of the first mover 2. At this time, the first magnet group 231 and the two second magnet groups 241 are located on different sides of the first mover 2, which can reduce the magnetic interference between the first magnet group 231 and the second magnet group 241.

[0118] Please refer to the following: Figures 7A to 8B , Figure 7A yes Figure 3 A schematic diagram of the arrangement of magnets in motor 10 of camera module 100 in some other embodiments; Figure 7B yes Figure 3A schematic diagram of the arrangement of magnets in motor 10 of camera module 100 in some other embodiments; Figure 8A yes Figure 3 A schematic diagram of the arrangement of magnets in motor 10 of camera module 100 in some other embodiments; Figure 8B yes Figure 3 The diagram shows the arrangement of magnets in the motor 10 of the camera module 100 in some embodiments. It should be noted that the coils are not shown in the diagram for clarity in illustrating the magnet arrangement.

[0119] It should be noted that, Figures 7A to 8B It can include Figure 5B Some features in the illustrated embodiments are described above; the same features will not be repeated here.

[0120] Please see Figure 7A In some embodiments, along the first direction Y, the projections of the second magnet group 241 and the third magnet group 31 can partially overlap, so that the arrangement space of the third magnet group 31 can reuse the space of the second magnet group 241, which is beneficial to reducing the length of the motor 10 in the second direction X.

[0121] Please see Figure 7B In other embodiments, the first magnet group 231 and the first coil 121 can be arranged opposite each other along the second direction X. That is, the first magnet group 231 can be located on the back side of the first mover 2. In this case, the first magnet group 231 and the two second magnet groups 241 are located on different sides of the first mover 2, which can reduce the magnetic interference between the first magnet group 231 and the second magnet group 241.

[0122] Please see Figure 8A In some embodiments, the second magnet group 241 and the second coil 122 can be arranged opposite to each other along the second direction X. That is, the second magnet group 241 can be located on the back side of the first mover 2. In this case, the first magnet group 231 and the two second magnet groups 241 are located on different sides of the first mover 2, which can reduce the magnetic interference between the first magnet group 231 and the second magnet group 241. In addition, the second magnet groups 241 do not need to be arranged on both sides of the first mover 2 in the first direction Y, and the second coil 122 does not need to be arranged on both sides of the base assembly 1 in the first direction Y, thus enabling a thinner design of the motor 10 in the first direction Y.

[0123] In the two second magnet groups 241, the magnetic poles of the second magnets that are set opposite to each other along the first direction Y point in opposite directions.

[0124] Please see Figure 8BIn some embodiments, the second magnet group 241 and the second coil 122 can be arranged opposite each other along the second direction X, and the first magnet group 231 and the first coil 121 can be arranged opposite each other along the second direction X. That is, the second magnet group 241 and the first magnet group 231 are both located on the back side of the first mover 2. This design is not only beneficial to the thinning design of the motor 10 in the first direction Y, but also beneficial to the thinning design of the motor 10 in the third direction Z.

[0125] In the two second magnet groups 241, the magnetic poles of the second magnets that are set opposite to each other along the first direction Y point in opposite directions.

[0126] Please refer to the following: Figures 9A to 10B , Figure 9A yes Figure 3 A schematic diagram of the arrangement of magnets in motor 10 of camera module 100 in some other embodiments; Figure 9B yes Figure 3 A schematic diagram of the arrangement of magnets in motor 10 of camera module 100 in some other embodiments; Figure 10A yes Figure 3 A schematic diagram of the arrangement of magnets in motor 10 of camera module 100 in some other embodiments; Figure 10B yes Figure 3 The diagram shows the arrangement of magnets in the motor 10 of the camera module 100 in some embodiments. It should be noted that the coils are not shown in the diagram for clarity in illustrating the magnet arrangement.

[0127] It should be noted that, Figures 9A to 10B It can include Figure 5B Some features in the illustrated embodiments are described above; the same features will not be repeated here.

[0128] In some embodiments, the second axis L2 can be parallel to the third direction Z, that is, the first mover 2 achieves optical image stabilization by shaking its head.

[0129] Please see Figure 9A In some embodiments, the first magnet group 231 and the first coil 121 can be arranged opposite each other along the second direction X, and the second magnet group 241 and the second coil 122 can be arranged opposite each other along the third direction Z. In this case, the first magnet group 231 and the two second magnet groups 241 are located on different sides of the first mover 2, which can reduce the magnetic interference between the first magnet group 231 and the second magnet group 241. In addition, the first mover 2 does not need to be provided with the second magnet groups 241 on both sides of the first direction Y, and the base assembly 1 does not need to be provided with the second coils 122 on both sides of the first direction Y, thus enabling a thinner design of the motor 10 in the first direction Y.

[0130] In each second magnet group 241, the magnetic poles of the second magnets closest to the second axis L2 point in opposite directions.

[0131] Please see Figure 9B In other embodiments, the first magnet group 231 and the first coil 121 can be arranged opposite each other along the third direction Z, and the second magnet group 241 and the second coil 122 can be arranged opposite each other along the third direction Z. This design not only facilitates the thinning design of the motor 10 in the first direction Y, but also facilitates the miniaturization design of the motor 10 in the second direction X.

[0132] In each second magnet group 241, the magnetic poles of the second magnets closest to the second axis L2 point in opposite directions.

[0133] Please see Figure 10A In some embodiments, the first magnet group 231 and the first coil 121 can be arranged opposite each other along the third direction Z, and the second magnet group 241 and the second coil 122 can be arranged opposite each other along the second direction X. In this case, the first magnet group 231 and the two second magnet groups 241 are located on different sides of the first mover 2, which can reduce the magnetic interference between the first magnet group 231 and the second magnet group 241. In addition, the first mover 2 does not need to be provided with the second magnet groups 241 on both sides of the first direction Y, and the base assembly 1 does not need to be provided with the second coils 122 on both sides of the first direction Y, thus enabling a thinner design of the motor 10 in the first direction Y.

[0134] In each second magnet group 241, the magnetic poles of the second magnets closest to the other second magnet group 241 point in opposite directions.

[0135] Please see Figure 10B In some embodiments, the first magnet group 231 and the first coil 121 can be arranged opposite each other along the second direction X, and the second magnet group 241 and the second coil 122 can be arranged opposite each other along the second direction X. This design not only facilitates the thinning design of the motor 10 in the first direction Y, but also facilitates the thinning design of the motor 10 in the third direction Z.

[0136] In each second magnet group 241, the magnetic poles of the second magnets closest to the other second magnet group 241 point in opposite directions.

[0137] Next, we will introduce the design of the motor 10 driving the optical path folding element 20 to rotate around the first axis L1.

[0138] Please refer to the following: Figures 11 to 13B , Figure 11 yes Figure 3 A schematic diagram of the motor 10 in some embodiments of the camera module 100 shown; Figure 12 yes Figure 11 A schematic diagram of the structure of the first mover 2 in some embodiments of the motor 10 shown; Figure 13A yes Figure 12The diagram shows the structure of the first moving part 2 after being cut along line C1-C1 in some embodiments; Figure 13B yes Figure 12 The diagram shows the structure of the first moving part 2 after being cut open along line C2-C2 in some embodiments.

[0139] In some embodiments, the first mover 2 may include a first carrier 232, a second carrier 242, and a first support member 21, with a first magnet group 231 fixed to the first carrier 232. The second carrier 242 is movably mounted to the first carrier 232 and to the base 11, with two second magnet groups 241 fixed to the second carrier 242. The first support member 21 is supported between the first carrier 232 and the second carrier 242, and includes a first support portion 211 and a second support portion 212 spaced apart in a first direction Y, with a first shaft L1 passing through the first support portion 211 and the second support portion 212.

[0140] In this embodiment, the first support portion 211 and the second support portion 212 support the first carrier 232 and the second carrier 242, providing rotational support for the first carrier 232 to rotate relative to the second carrier 242 around the first axis L1. This can improve the stability of the first carrier 232 rotating relative to the second carrier 242 around the first axis L1, thereby improving the stability of optical image stabilization when the motor 10 is applied to the camera module 100.

[0141] For example, the first mover 2 may further include a first pre-compression member 22, which includes a first magnetic attracting magnet 233 and a first magnetic element 243, one of which is fixed to the first carrier 232 and the other is fixed to the second carrier 242. The first magnetic attracting magnet 233 and the first magnetic element 243 are arranged opposite to each other along the support arrangement direction of the first carrier 232, the first support member 21 and the second carrier 242.

[0142] In this embodiment, the design of the first magnetic attracting magnet 233 and the first magnetic element 243 provides a magnetic attraction force that brings the first carrier 232 and the second carrier 242 closer together. This allows the first support member 21 to be stably supported between the first carrier 232 and the second carrier 242, thereby improving the stability of the first carrier 232 rotating relative to the second carrier 242 around the first axis L1. Furthermore, during the rotation of the first carrier 232 relative to the second carrier 242 around the first axis L1, the first magnetic attracting magnet 233 and the first magnetic element 243 can also provide a magnetic restoring torque to the first carrier 232 through magnetic attraction, thus facilitating the centering of the first carrier 232.

[0143] The first magnetic magnet 233 and the first magnetic component 243 can be arranged at intervals, which helps to reduce the sensitivity of the first preload component 22 to the installation tolerance of the first magnetic magnet 233 and the first magnetic component 243, thereby helping the first preload component 22 to provide more stable magnetic preload and magnetic restoring torque.

[0144] The first magnetic magnet 233 can be fixed to the first carrier 232, and the first magnetic component 243 can be fixed to the second carrier 242. The first magnetic component 243 is made of soft magnetic material, which can reduce the magnetic interference of the first magnetic magnet 233 from other magnets.

[0145] In the direction perpendicular to the first axis L1 and perpendicular to the arrangement direction of the first magnetic magnet 233 and the first magnetic element 243, the first magnetic magnet 233 and the first magnetic element 243 have different sizes, with the larger one extending beyond the smaller one at both ends.

[0146] In this embodiment, the above design ensures that during the rotation of the first carrier 232 relative to the second carrier 242 around the first axis L1, the area of ​​the directly facing region between the first magnetic magnet 233 and the first magnetic component 243 remains basically unchanged, thereby reducing the sensitivity to the installation tolerance of the first magnetic magnet 233 and the first magnetic component 243.

[0147] In particular, along the direction perpendicular to the first axis L1 and perpendicular to the arrangement direction of the first magnetic attracting stone 233 and the first magnetic element 243, the two ends of the larger of the first magnetic attracting stone 233 and the first magnetic element 243 are different in size from the smaller one. This ensures that the magnetic restoring torque of the first pre-compression member 22 is 0 when the first carrier 232 is not rotating relative to the second carrier 242 under the influence of other magnetic interference. This can prevent the first carrier 232 from detaching from the second carrier 242 after the motor 10 is powered off, which would cause the optical path folding element 20 to be biased.

[0148] For example, the first magnetic attracting stone 233 and the first magnetic element 243 can be arranged opposite each other along the second direction X. Along the third direction Z, the first magnetic attracting stone 233 and the first magnetic element 243 have different sizes, with the larger one extending beyond the smaller one at both ends in the third direction Z, and the extensions at both ends are different.

[0149] Please refer to the following: Figure 14A and Figure 14B , Figure 14A This is a simulation diagram illustrating the variation of the magnetic restoring torque provided by the first preload member 22 with installation tolerance in some other embodiments; Figure 14B yes Figure 13B The simulation diagram shows the variation of the magnetic restoring torque provided by the first preloaded component 22 with the installation tolerance.

[0150] It should be noted that, Figure 14A and Figure 14B Different lines represent the variation of the magnetic restoring torque provided by the first preloaded component 22 with the rotation angle under different installation tolerances. The direction and the number together represent the installation tolerance values ​​in different directions. Specifically, when the magnetic restoring torque on the vertical axis is 0 mN / mm, the smaller the absolute value of the difference between the vertical axis and the line with no tolerance on the horizontal axis, the smaller the deviation of the rotation angle, which allows the first carrier 232 to have a better centering effect.

[0151] Please see Figure 14A In other embodiments, the first magnetic attracting stone 233 and the first magnetic element 243 are arranged opposite each other. No direction is designed perpendicular to the first axis L1 and perpendicular to the arrangement direction of the first magnetic attracting stone 233 and the first magnetic element 243. The first magnetic attracting stone 233 and the first magnetic element 243 have different sizes; the larger one extends beyond the smaller one at both ends, and the extent of the extension at both ends is different. Figure 14A Simulation results show that the installation tolerance of the first preloaded component 22 in the second direction X will significantly affect the magnetic restoring torque of the first preloaded component 22, and the rotation angle offset is greater than 0.5° when the magnetic restoring torque is 0 mN / mm.

[0152] Please see Figure 14B , Figure 14B according to Figure 13B The simulation of the embodiment shown shows that, under different directions and different installation tolerances, the rotation angle offset of the magnetic restoring torque of the first preload 22 is less than 0.5° when it is 0mN / mm, which can improve the centering effect of the first carrier 232 and prevent the optical path folding element 20 carried by the first carrier 232 from being biased when the motor 10 is powered off.

[0153] Please refer to the following: Figures 15A to 17B , Figure 15A yes Figure 12 The diagram shown is a partial structural exploded view of the first mover 2 in some embodiments. Figure 15B yes Figure 15A A schematic diagram of the structure of the first mover 2 from another perspective; Figure 16A yes Figure 15A The diagram shown is a structural schematic of the first load-bearing component 23 in some embodiments; Figure 16B yes Figure 16A The diagram shown is a partial structural exploded view of the first load-bearing component 23 in some embodiments. Figure 17A yes Figure 15A The diagram shown is a structural schematic of the second support component 24 in some embodiments; Figure 17B yes Figure 17A The second support component 24 shown is a partial structural exploded view in some embodiments.

[0154] Please see Figure 15A and Figure 15B In some embodiments, the first moving part 2 may include a first bearing component 23, a first support member 21, and a second bearing component 24. The first support member 21 may be supported between the first bearing component 23 and the second bearing component 24.

[0155] Please see Figure 16A and Figure 16B For example, the first carrier component 23 may include a first carrier 232, a first magnet group 231, a first magnetic attracting magnet 233, a first sensing magnet 234, and two first elastic members 235. The first magnet group 231, the first magnetic attracting magnet 233, the first sensing magnet 234, and the two first elastic members 235 are all mounted on the first carrier 232.

[0156] The first carrier 232 may include a first main body 2321, a first plate 2322, a second plate 2323, a first extension arm 2324, and a second extension arm 2325. The first plate 2322 and the second plate 2323 may be arranged opposite to each other along a first direction Y, and the first main body 2321 may be connected between the first plate 2322 and the second plate 2323. The first extension arm 2324 may be connected to the side of the first plate 2322 facing away from the second plate 2323, and the second extension arm 2325 may be connected to the side of the second plate 2323 facing away from the first plate 2322.

[0157] The first body 2321 may have a bearing surface 2326 for bearing the optical path folding element 20. A first magnet group 231 and a first sensing magnet 234 may be installed on the side of the first body 2321 facing away from the bearing surface 2326 along the third direction Z. A first magnetic attraction magnet 233 may be installed on the side of the first body 2321 facing away from the bearing surface 2326 along the second direction X.

[0158] The first extension arm 2324 and the second extension arm 2325 may be provided with grooves for accommodating the first support portion 211 and the second support portion 212, respectively.

[0159] Please see Figure 13A and Figure 16B One first elastic element 235 can be installed on the side of the first plate 2322 facing away from the second plate 2323, and the other first elastic element 235 can be installed on the side of the second plate 2323 facing away from the first plate 2322. This allows the two first elastic elements 235 to connect between the first carrier 232 and the second carrier 242, providing elastic restoring force to the first carrier 232, improving its centering ability, and providing resistance to the first carrier 232, thereby improving the stability of the first carrier 232 rotating relative to the second carrier 242 around the first axis L1.

[0160] Please refer to the following: Figure 17A and Figure 17B For example, the second carrier component 24 may include a second carrier 242, two second magnet groups 241, a first magnetic element 243, a second magnetic element 244, and a second sensing magnet 245. The two second magnet groups 241, the first magnetic element 243, the second magnetic element 244, and the second sensing magnet 245 may all be fixed to the second carrier 242.

[0161] The second carrier 242 may include a third plate 2421, a fourth plate 2422 and a fifth plate 2423. The third plate 2421 and the fifth plate 2423 may be arranged opposite to each other along the first direction Y, and the fourth plate 2422 may be connected between the third plate 2421 and the fifth plate 2423.

[0162] The two second magnet groups 241 can be installed on the side of the third plate 2421 facing away from the fifth plate 2423 and the side of the fifth plate 2423 facing away from the third plate 2421, respectively.

[0163] The first magnetic component 243 and the second magnetic component 244 can be installed on opposite sides of the fourth plate 2422.

[0164] The second sensing magnet 245 can be mounted on the same side of the fourth plate 2422 as the second magnetic component 244.

[0165] Next, we will introduce the design of the motor 10 driving the optical path folding element 20 to rotate around the second axis L2.

[0166] Please refer to the following: Figures 18 to 21 , Figure 18 yes Figure 3 The diagram shows a partial structural exploded view of the motor 10 in some embodiments. Figure 19 yes Figure 18 An exploded view of part of the structure of the base assembly 1 in some embodiments of the motor 10 shown; Figure 20A yes Figure 19 The diagram shows a structural schematic of the base assembly 1 in some embodiments where the second support member 7 is installed; Figure 20B yes Figure 20A A schematic diagram of the structure shown from another perspective; Figure 21 yes Figure 20A The diagram shows a structural schematic of the base assembly 1 in some embodiments, in which the first moving part 2 is mounted.

[0167] Please see Figure 4A and Figure 18In some embodiments, the motor 10 may further include a second support 7, which can be supported between the first mover 2 and the base assembly 1, with the second shaft L2 passing through the second support 7. The design of the second support 7 provides rotational support for the first mover 2 to rotate relative to the base assembly 1 about the second shaft L2, thereby improving the stability of the first mover 2 rotating relative to the base assembly 1 about the second shaft L2.

[0168] Please see Figure 19 In some embodiments, the base assembly 1 may include a base 11, a circuit assembly 12, a second magnetic magnet 13, a first damping adhesive 14, a buffer 15, and a guide 16.

[0169] For example, circuit assembly 12 may include a first coil 121, two second coils 122, two third coils 123, a first position sensor 124, and a second position sensor 125.

[0170] Please see Figure 20A and Figure 20B For example, the base 11 may include a bottom wall 111, a first side wall 112, a second side wall 113, a third side wall 114, a first partition arm 115, and a second partition arm 116. The first side wall 112, second side wall 113, third side wall 114, first partition arm 115, and second partition arm 116 may all protrude from the same side of the bottom wall 111, forming a receiving space 117. The first side wall 112 and third side wall 114 may be arranged opposite each other along a first direction Y. The second side wall 113 may be connected between the first side wall 112 and the third side wall 114. The first partition arm 115 may be connected to the side of the first side wall 112 facing the third side wall 114, and the second partition arm 116 may be connected to the side of the third side wall 114 facing the first side wall 112, and the first partition arm 115 and second partition arm 116 may be arranged opposite each other along the first direction Y.

[0171] The second magnetic magnet 13 can be installed on the second side wall 113.

[0172] The second support member 7 can be installed on the second side wall 113.

[0173] The second support member 7 may include a third support part 71, a fourth support part 72 and a fifth support part 73, and the third support part 71, the fourth support part 72 and the fifth support part 73 may be located on different sides of the second magnetic magnet 13.

[0174] The first coil 121 can be installed on the bottom wall 111.

[0175] The two second coils 122 can be installed on the first side wall 112 and the third side wall 114 respectively.

[0176] The two third coils 123 can be installed on the first side wall 112 and the third side wall 114 respectively, and the third coils 123 and the second coils 122 are arranged at intervals along the second direction X.

[0177] The first position sensor 124 can be installed on the bottom wall 111.

[0178] The second position sensor 125 can be installed on the second side wall 113.

[0179] The first damping adhesive 14 can be installed on the second sidewall 113.

[0180] The number of buffer members 15 can be two, and the two buffer members 15 are respectively installed on the side of the first partition arm 115 and the second partition arm 116 facing the second side wall 113.

[0181] The guide member 16 can be two in number. Both guide members 16 can be installed on the bottom wall 111 and located between the two third coils 123. The two guide members 16 are arranged at intervals along the first direction Y. The guide members 16 are used to guide the second mover 3 to move relative to the base 11 along the second direction X.

[0182] Please see Figure 21 In some embodiments, the first damping adhesive 14 can be elastically connected to the second carrier 242 and the base 11, so that the first damping adhesive 14 can provide damping for the rotation of the first mover 2 relative to the base 11 about the second axis L2, thereby improving the stability of the rotation of the first mover 2 relative to the base 11 about the second axis L2. In addition, the first damping adhesive 14 can also provide a restoring torque for the rotation of the first mover 2 relative to the base 11 about the second axis L2, thereby improving the return-to-center capability of the first mover 2.

[0183] Please see Figure 22A and Figure 22B , Figure 22A The simulation results are for the steady-state current of the motor 10 driving the first mover 2 to rotate about the second axis L2 relative to the base 11 in some other embodiments; Figure 22B yes Figure 21 The simulation results show the steady-state current of the motor 10 driving the first mover 2 to rotate relative to the base 11 about the second axis L2.

[0184] It should be noted that, Figure 22A and Figure 22B The horizontal axis represents the number of motors 10 used in the test, and the vertical axis represents the steady-state current of each motor 10 driving the first mover 2 to rotate relative to the base 11 around the second axis L2. The smaller the difference in steady-state current between motors 10 with different numbers, the better the consistency of the motor 10 control characteristics.

[0185] Please see Figure 22A In some other embodiments, the first moving element 2 is not connected to the base 11 by a first damping adhesive 14. Figure 22A Simulations show that the difference in steady-state currents between the multiple motors 10 driving the first mover 2 to rotate about the second axis L2 relative to the base 11 is significant. Therefore, Figure 22A The control characteristics of the motor 10 in the corresponding embodiment have poor consistency.

[0186] Please see Figure 22B ,correspond Figure 21 The motor 10 shown can be elastically connected to the second carrier 242 and the base 11 via a first damping adhesive 14, so that the first damping adhesive 14 can provide damping for the rotation of the first mover 2 relative to the base 11 around the second axis L2, thereby improving the stability of the rotation of the first mover 2 relative to the base 11 around the second axis L2. Figure 22B Simulation results show that the difference between the steady-state currents of multiple motors 10 driving the first mover 2 to rotate about the second axis L2 relative to the base 11 is small, which significantly improves the consistency of the control characteristics of the motors 10. Furthermore, in this embodiment, the value of the steady-state current of each motor 10 driving the first mover 2 to rotate about the second axis L2 relative to the base 11 is relatively small compared to... Figure 22A The corresponding embodiments are significantly reduced, and therefore, power consumption is also reduced through the design of the first damping adhesive 14.

[0187] Please refer to the following: Figure 23A and Figure 23B , Figure 23A yes Figure 11 A partial structural diagram of the motor 10 shown in some embodiments after being cut open along line D1-D1. Figure 23B yes Figure 11 The diagram shows a partial structural schematic of the motor 10 as shown after being cut along line D2-D2 in some embodiments.

[0188] In some embodiments, the second magnetic magnet 13 installed on the base 11 and the second magnetic element 244 installed on the second carrier 242 can be arranged opposite to each other along the second direction X to form a second pre-pressure element 8, so as to provide a pre-pressure to magnetically attract the first mover 2 to the second side wall 113 of the base 11, thereby making the installation stability between the first mover 2, the second support element 7 and the base 11.

[0189] For example, the second magnetic element 244 can be a soft magnetic material. Since the first magnet group 231 is installed on the first carrier 232 and the second magnet group 241 is installed on the second carrier 242, installing the second magnetic attracting magnet 13 on the base 11 can reduce the magnetic interference of the first magnet group 231 and the second magnet group 241 on the second magnetic attracting magnet 13. This reduces the sensitivity of the second preload member 8 to the installation tolerance of the second magnetic attracting magnet 13 and the second magnetic element 244, which is beneficial to providing more stable magnetic attraction. This is not only beneficial to the stability of the first mover 2 rotating around the second axis L2 relative to the base 11, but also beneficial to improving the return-to-center capability of the second mover 3.

[0190] In some embodiments, the base assembly 1 may further include two third magnetic elements 17, which are fixed to the base 11 and arranged at intervals in the first direction Y. The third magnetic elements 17 are located on the side of the second coil 122 facing away from the second magnet group 241, and the two third magnetic elements 17 are arranged opposite to the second magnet group 241.

[0191] In this embodiment, the third magnetic element 17 interacts with the second magnet group 241 to generate a magnetic attraction force, thereby providing a magnetic restoring force for the rotation of the first mover 2 relative to the base 11 around the second axis L2. This not only improves the stability of the rotation of the first mover 2 relative to the base 11 around the second axis L2, but also enhances the centering capability of the second mover 3. Due to the design of the third magnetic element 17, the magnetic restoring torque required for the rotation of the first mover 2 relative to the base 11 around the second axis L2 does not rely solely on the second preload element 8. Therefore, the design of the third magnetic element 17 reduces the sensitivity to the installation tolerances of the second magnetic attracting magnet 13 and the second magnetic element 244, which is beneficial to the stability of the rotation of the first mover 2 relative to the base 11 around the second axis L2.

[0192] For example, the third magnetic element 17 may have an opening to prevent the magnetic attraction force of the third magnetic element 17 on the second magnet group 241 from being too large, thereby reducing the risk of resistance to the rotation of the first mover 2 relative to the base 11 around the second axis L2 caused by the excessive magnetic attraction force, which is conducive to a smoother rotation of the first mover 2 relative to the base 11 around the second axis L2.

[0193] Please see Figure 24A and Figure 24B , Figure 24A This is a simulation diagram showing the variation of the magnetic restoring torque of the motor 10 driving the first mover 2 to rotate relative to the base 11 about the second axis L2 as a function of installation tolerance in some other embodiments. Figure 24B yes Figure 23B The simulation diagram shown in the embodiment illustrates the variation of the magnetic restoring torque of the motor 10 driving the first mover 2 to rotate relative to the base 11 about the second axis L2 with the installation tolerance.

[0194] It should be noted that, Figure 24A The different lines represent the variation of the magnetic restoring torque on the first mover 2 with the rotation angle under different installation tolerances of the second preloaded component 8. The direction combined with the number indicates the installation tolerance value in different directions.

[0195] Figure 24B Different lines represent the changes in magnetic restoring torque experienced by the first mover 2 with rotation angle under different installation tolerances of the two third magnetic components 17. The direction combined with the number indicates the installation tolerance value in different directions; same direction indicates that the two third magnetic components 17 have installation tolerances in the same direction, and opposite direction indicates that the two third magnetic components 17 have installation tolerances in opposite directions.

[0196] When the magnetic restoring torque on the vertical axis is 0 mN / mm, the smaller the absolute value of the difference between the vertical axis and the line without tolerance on the horizontal axis, the smaller the deviation of the rotation angle, which enables the first mover 2 to have a better centering effect.

[0197] Please see Figure 24A In some other embodiments, the motor 10 does not have a third magnetic element 17, so the magnetic restoring torque for the first mover 2 to rotate relative to the base 11 about the second axis L2 is provided solely by the second preload element 8. Figure 24A The simulation results show that the magnetic restoring torque of the first mover 2 rotating about the second axis L2 relative to the base 11 is significantly affected by the installation tolerance in the first direction Y, with a rotation angle difference of about 1.5°.

[0198] Please see Figure 24B , Figure 24B Corresponding to Figure 23B The embodiment shown reduces the sensitivity of the magnetic restoring torque of the first mover 2 rotating relative to the base 11 about the second axis L2 to the installation tolerance through the design of the second preload member 8 and the third magnetic member 17. Taking the installation tolerance of the two third magnetic members 17 as an example, from Figure 24B Simulation results show that when both first magnetic components 243 have an installation tolerance of 0.025mm in the positive direction of the first direction Y, the magnetic restoring torque of the first mover 2 rotating relative to the base 11 about the second axis L2 is most affected by the installation tolerance in the first direction Y. However, the difference in rotation angle is less than 0.5°. It can be seen that the sensitivity of the magnetic restoring torque of the first mover 2 rotating relative to the base 11 about the second axis L2 to the installation tolerance is significantly reduced, which enables the first mover 2 to have a better centering effect.

[0199] Please refer to the following: Figure 13B and Figure 23AIn some embodiments, the first magnet group 231 and the first sensing magnet 234 installed on the first carrier 232 are exposed on the second carrier 242 via the bottom of the first carrier 232, so that the first magnet group 231 can be arranged relative to the first coil 121 installed on the bottom wall 111 along the third direction Z to form the first driving member 4, and the first sensing magnet 234 can be arranged relative to the first position sensor 124 installed on the bottom wall 111 along the third direction Z to realize position detection.

[0200] In this embodiment, the first driving member 4 can drive the first carrier 232 to rotate relative to the base 11 around the first axis L1. At the same time, the first position sensor 124 detects the magnetic field of the first sensing magnet 234, which can obtain the position change of the first carrier 232 relative to the base 11, thereby obtaining the angle of rotation of the first carrier 232 relative to the base 11 around the first axis L1. This not only provides rotation angle analysis for the motor 10 to achieve optical image stabilization, but also provides rotation angle feedback during the process of the motor 10 performing optical image stabilization, so as to achieve closed-loop control and improve the accuracy of optical image stabilization.

[0201] Please refer to the following: Figure 13A and Figure 25 , Figure 25 yes Figure 11 The diagram shows a partial structural schematic of the motor 10 in some embodiments after being cut open along line D3-D3.

[0202] In some embodiments, the second sensing magnet 245 mounted on the second carrier 242 can be arranged opposite to the second position sensor 125 mounted on the second sidewall 113 of the base 11 along the second direction X, so that the second position sensor 125 can detect the magnetic field of the second sensing magnet 245 and obtain the position change of the second carrier 242 relative to the base 11, thereby obtaining the angle of rotation of the second carrier 242 relative to the base 11 about the second axis L2. This not only provides rotation angle analysis for the motor 10 to achieve optical image stabilization, but also provides rotation angle feedback during the optical image stabilization process of the motor 10, so as to achieve closed-loop control and improve the accuracy of optical image stabilization.

[0203] The structure of motor 10 in some embodiments has been described above. The structure of motor 10 in other embodiments will be described below.

[0204] Please refer to the following: Figure 26A and Figure 26B , Figure 26A yes Figure 3 A partial structural schematic diagram of the camera module 100 shown in some embodiments after being cut open along line A1-A1; Figure 26B yes Figure 3 The diagram shows a partial structural representation of the camera module 100 as shown after it has been cut open along line A2-A2 in some other embodiments.

[0205] It should be noted that, Figure 26A and Figure 26B The motor 10 in the camera module 100 shown may include some features of any of the motors 10 in the foregoing embodiments, and the same features will not be described again here.

[0206] In some embodiments, the first support member 21 can be supported between the first carrier 232 and the second carrier 242 of the first mover 2, and the second shaft L2 passes through the first support member 21. The second support member 7 can be supported between the second carrier 242 and the base 11. The second support member 7 may include a third support portion 71 and a fourth support portion 72 spaced apart in the first direction Y, and the first shaft L1 passes through the third support portion 71 and the fourth support portion 72.

[0207] In this embodiment, the arrangement of the first carrier 232, the second carrier 242, the first support member 21 and the second support member 7 is designed so that the motor 10 can drive the first carrier 232 to drive the optical path folding element 20 to rotate relative to the base 11 around the second axis L2, and can drive the second carrier 242 to drive the first carrier 232 and the optical path folding element 20 to rotate together relative to the base 11 around the first axis L1, thereby achieving optical image stabilization with two-axis rotation.

[0208] For example, the first magnet group 231 can be fixed to the side of the second carrier 242 facing the second sidewall 113 of the base 11, and the first coil 121 can be fixed to the second sidewall 113 of the base 11, so that the first magnet group 231 and the first coil 121 can be arranged opposite to each other along the second direction X, and form the first driving member 4. The first driving member 4 is used to drive the second carrier 242 to drive the first carrier 232 and the optical path folding element 20 to rotate relative to the base 11 around the first axis L1.

[0209] In this configuration, one of the first magnetic attracting magnet 233 and the first magnetic component 243 is installed at the bottom of the second carrier 242, and the other is installed on the bottom wall 111 of the base 11, so that the first magnetic attracting magnet 233 and the first magnetic component 243 are arranged opposite each other along the third direction Z to form the first pre-compression component 22. The first pre-compression component 22 provides magnetic restoring torque for the first mover 2 to rotate relative to the base 11 around the first axis L1, thereby improving the centering capability of the first mover 2.

[0210] Along the second direction X, the first magnetic attractor 233 and the first magnetic element 243 have different dimensions. The larger one extends beyond the smaller one in the second direction X at both ends, and the extent of the extension is different. This helps to reduce the sensitivity of the magnetic restoring torque provided by the first preload element 22 to installation tolerances.

[0211] For example, two second magnet groups 241 can be installed on both sides of the first carrier 232 along the first direction Y, and two second coils 122 can be installed on both sides of the base 11 along the first direction Y, so that the two second magnet groups 241 and the two second coils 122 can be arranged opposite to each other and combined to form a second driving member 5. The second driving member 5 is used to drive the first carrier 232 to drive the optical path folding element 20 to rotate relative to the base 11 around the second axis L2.

[0212] Among them, one of the second magnetic magnet 13 and the second magnetic component 244 can be installed on the first carrier 232 and the other can be installed on the second carrier 242. The second magnetic magnet 13 and the second magnetic component 244 can be arranged opposite to each other along the second direction X to form the second pre-compression component 8. The second pre-compression component 8 can provide magnetic restoring torque for the first carrier 232 to rotate relative to the base 11 around the second axis L2, thereby improving the centering ability of the first carrier 232.

[0213] It should be noted that the embodiments of this application illustrate some embodiments of the motor 10. In other embodiments, the specific structure of the motor 10 may be further customized. Figures 7A to 10B The arrangement of the magnets shown has been adjusted schematically.

[0214] The following describes the magnet arrangement design for achieving optical image stabilization in the motor in other embodiments.

[0215] Please refer to the following: Figures 27A to 29 , Figure 27A This is a schematic diagram of the magnet in the motor 10 provided in this application in some other embodiments; Figure 27B This is a schematic diagram of the magnet in the motor 10 provided in this application in some other embodiments; Figure 28A This is a schematic diagram of the magnet in the motor 10 provided in this application in some other embodiments; Figure 28B This is a schematic diagram of the magnet in the motor 10 provided in this application in some other embodiments; Figure 29 This is a schematic diagram of the magnet in the motor 10 provided in this application in some other embodiments.

[0216] In some embodiments, the motor 10 can be used to drive the first mover 2 to move relative to the base 11 along the third and fourth axes, thereby achieving optical image stabilization.

[0217] For example, a first driving member is used to drive at least a portion of the first mover 2 to move relative to the base 11 in a direction parallel to a third axis, and a second driving member is used to drive at least a portion of the first mover 2 to move relative to the base 11 in a direction parallel to a fourth axis, which intersects the third axis.

[0218] Each third magnet group 31 includes a third magnet 311, and the magnetic poles of the two third magnets 311 arranged opposite each other in the two third magnet groups 31 point in the same direction and are perpendicular to the third coil 123.

[0219] In this embodiment, the design of the third magnet group 31 enables the forces exerted by the two third magnet groups 31 on the first magnet group 231 to be opposite in direction in the direction parallel to the third axis, thereby reducing or even eliminating the magnetic interference of the second mover 3 on the first magnet group 231.

[0220] For example, a fifth magnetic force exists between the third magnet group 31 and the second magnet group 241 on one side of the motor 10. The force exerted by the fifth magnetic force on the second magnet group 241 has a seventh component force, which is parallel to the fourth axis. A sixth magnetic force exists between the third magnet group 31 and the second magnet group 241 on the other side of the motor 10. The force exerted by the sixth magnetic force on the second magnet group 241 has an eighth component force, which is parallel to the fourth axis, and the direction of the eighth component force is opposite to that of the seventh component force.

[0221] The center line connecting the two second magnet groups 241 has a perpendicular bisector. Each second magnet group 241 includes a second magnet 2411. The second magnets 2311 in the two second magnet groups 241 are mirror-symmetrical about the perpendicular bisector, so that the direction of the eighth component force can be opposite to the direction of the seventh component force, thereby reducing or even eliminating the magnetic interference of the second mover on the second magnet group 241.

[0222] It should be noted that the mirror symmetry of the second magnets 2311 in the two second magnet groups 241 about the perpendicular bisector means that after mirror symmetry, the second magnet 2311 in one of the second magnet groups 241 coincides with the second magnet 2311 in the other second magnet group 241, and the magnetic poles of the two coincident second magnets 2311 point in the same direction. However, the overlap of the two second magnets 2311 does not require them to be completely identical; dimensional deviations are allowed.

[0223] Please see Figure 27A The first magnet group 231 can be arranged opposite to the first coil 121 along the third direction Z, and correspondingly, the third axis is parallel to the second direction X. The second magnet group 241 can be arranged opposite to the second coil 122 along the first direction Y, and correspondingly, the fourth axis is parallel to the third direction Z.

[0224] Specifically, the magnetic force exerted by the third magnet group 31a on the first magnet group 231 has a fifth component force parallel to the third axis (see [link to relevant documentation]). Figure 27A (F41 in the text), the magnetic force exerted by the third magnet group 31b on the first magnet group 231 has a sixth component force parallel to the third axis (see F41 in the text). Figure 27A(F42 in the equation), the sixth component force points in the opposite direction to the fifth component force.

[0225] The magnetic force exerted by the third magnet group 31a on the second magnet group 241a has a seventh component force parallel to the fourth axis (see [link]). Figure 27A In F51), the magnetic force exerted by the third magnet group 31b on the second magnet group 241b has an eighth component force parallel to the fourth axis (see F51). Figure 27A (F61 in the equation), the eighth component force points in the opposite direction to the seventh component force.

[0226] Each second magnet group 241 has a second magnet 2411, the magnetic pole direction of the second magnet 2411 is perpendicular to the second coil 122, and the magnetic poles of the second magnets 2411 arranged opposite to each other along the first direction Y in the two second magnet groups 241 have opposite magnetic pole directions.

[0227] Understandably, in subsequent embodiments, all can be achieved through... Figure 27A The same principle is used in the embodiment to reduce or even eliminate the magnetic interference of the second mover 3 on the first mover 2.

[0228] Please see Figure 27B The first magnet group 231 can be arranged opposite to the first coil 121 along the third direction Z, and correspondingly, the third axis is parallel to the second direction X. The second magnet group 241 can be arranged opposite to the second coil 122 along the second direction X, and correspondingly, the fourth axis is parallel to the third direction Z.

[0229] Each second magnet group 241 has a second magnet 2411, the magnetic pole of the second magnet 2411 is perpendicular to the second coil 122, and the magnetic poles of the second magnets 2411 arranged opposite each other in the first direction Y in the two second magnet groups 241 have the same magnetic pole direction.

[0230] Please see Figure 28A The first magnet group 231 can be arranged opposite to the first coil 121 along the second direction X, and correspondingly, the third axis is parallel to the third direction Z. The second magnet group 241 can be arranged opposite to the second coil 122 along the third direction Z, and correspondingly, the fourth axis is parallel to the second direction X.

[0231] Each second magnet group 241 has a second magnet 2411, the magnetic pole of the second magnet 2411 is perpendicular to the second coil 122, and the magnetic poles of the second magnets 2411 arranged opposite each other in the first direction Y in the two second magnet groups 241 have the same magnetic pole direction.

[0232] Please see Figure 28BThe first magnet group 231 can be arranged opposite to the first coil 121 along the third direction Z, and correspondingly, the third axis is parallel to the second direction X. The second magnet group 241 can be arranged opposite to the second coil 122 along the second direction X, and correspondingly, the fourth axis is parallel to the first direction Y.

[0233] Each second magnet group 241 has a second magnet 2411, the magnetic pole of the second magnet 2411 is perpendicular to the second coil 122, and the magnetic poles of the second magnet 2411 in each second magnet group 241 that are close to another magnet group have the same magnetic pole orientation.

[0234] Please see Figure 29 The first magnet group 231 can be arranged opposite to the first coil 121 along the second direction X, and correspondingly, the third axis is parallel to the third direction Z. The second magnet group 241 can be arranged opposite to the second coil 122 along the second direction X, and correspondingly, the fourth axis is parallel to the first direction Y.

[0235] Each second magnet group 241 has a second magnet 2411, the magnetic poles of the second magnet 2411 are perpendicular to the second coil 122, and the magnetic poles of the two inner second magnets 2411 in the two second magnet groups 241 are in the same direction.
