Description

[0001] This application is a divisional application. The original application has the application number 202110486281.6 and the original application date is April 30, 2021. The entire contents of the original application are incorporated herein by reference. Technical Field

[0002] This application relates to the field of camera technology, and more particularly to a stabilization motor, camera module, and electronic device. Background Technology

[0003] With the widespread adoption and development of smartphones, mobile phone photography has become a common way for people to take pictures, and phones with optical image stabilization are increasingly favored by users. Optical image stabilization technology is gradually evolving from the electromagnetic force suspension-type image stabilization technology of traditional voice coil motors (VCM) to the thermoelectric image stabilization technology of shape memory alloy (SMA) motors.

[0004] Traditional SMA motors consist of a drive electrode layer and multiple SMA wires. The drive electrode layer has multiple electrode plates. These electrode plates provide drive electrodes for multiple SMA wires. However, because the multiple electrode plates in the drive electrode layer are arranged in an interlaced and disordered manner, the SMA motor requires many leads to be arranged in the peripheral area of ​​the drive electrode layer to meet electrical connection requirements, thus making the structure of the SMA motor complex. Summary of the Invention

[0005] This application provides a simple image stabilization motor, camera module, and electronic device.

[0006] In a first aspect, embodiments of this application provide a stabilization motor. The stabilization motor includes a bridging layer, an electrode assembly, a spring, and multiple SMA wires. The electrode assembly is stacked on one side of the bridging layer. The spring is located on the side of the electrode assembly away from the bridging layer. The multiple SMA wires are arranged around the spring. One end of each SMA wire is connected to the spring, and the other end is connected to the electrode assembly.

[0007] The electrode assembly includes a common electrode and a drive electrode spaced apart. A reed contacts the common electrode. The drive electrode includes a first conductive sheet and a second conductive sheet spaced apart. The bridging layer includes a bridging member. The bridging member connects the first conductive sheet and the second conductive sheet. The SMA line includes a first SMA line. One end of the first SMA line is connected to the reed, and the other end is connected to the second conductive sheet. The first conductive sheet is used to connect external components of the stabilization motor. The common electrode, the reed, the first SMA line, the first conductive sheet, the second conductive sheet, and the bridging member form a partial current loop.

[0008] It is understandable that by providing a bridging layer on one side of the electrode assembly and using the bridging components of the bridging layer to connect the first and second conductive plates of the drive electrode, on the one hand, the problem of the first and second conductive plates being difficult to connect when spaced apart can be solved in the compact structure of the electrode assembly, that is, the positional constraints of the first and second conductive plates can be released; on the other hand, the surrounding area of ​​the drive electrode layer does not need to be arranged with many leads to meet the electrical connection requirements. In this way, the arrangement of the drive electrodes on the electrode assembly is more regular, and the structure of the anti-shake motor is relatively simple.

[0009] Furthermore, compared to the approach of arranging leads around the driving electrode layer, this approach, although adding a bridging layer to the thickness of the stabilization motor, allows for a significantly smaller bridging layer. In this case, the volume of the bridging layer is negligible compared to the overall volume of the stabilization motor. Therefore, the size of the stabilization motor in this approach can be greatly reduced, meaning the stabilization motor can be miniaturized.

[0010] Furthermore, when a signal is applied to the current loop formed by the common electrode, the reed, the first SMA line, the first conductive sheet, the second conductive sheet, and the bridging element, the first SMA line is energized and heated, causing it to contract and thus generating a corresponding tension on the reed. The reed can move to any position relative to the electrode assembly. When the reed is used to fix the lens of the camera module, because the reed can move to any position relative to the electrode assembly, it can drive the lens to move to any position relative to the electrode assembly, enabling the lens of the camera module to achieve optical image stabilization.

[0011] In one possible implementation, the bridging layer includes a first sublayer and a second sublayer stacked together. Electrode assemblies are stacked on the second sublayer. The first sublayer includes a conductive portion. The second sublayer includes an adhesive portion and first and second conductive posts spaced apart. The adhesive portion is made of an insulating material. The adhesive portion is stacked on the conductive portion. Electrode assemblies are stacked on the adhesive portion. Both the first and second conductive posts are embedded in the adhesive portion, and both the first and second conductive posts are also connected to the conductive portion. The conductive portion, the first conductive post, and the second conductive post form a bridging member.

[0012] Understandably, on the one hand, the adhesive portion can insulate and separate the conductive portion from the electrode assembly. On the other hand, the first conductive sheet and the second conductive sheet can be connected through the conductive portion, the first conductive post, and the second conductive post. The bridging layer has a "multi-purpose" effect. In addition, the structure of the bridging member formed by the conductive portion, the first conductive post, and the second conductive post is relatively simple and easy to implement.

[0013] In one possible implementation, the first sublayer further includes a flat portion, a first connecting portion, and a second connecting portion. The flat portion is disposed opposite to the conductive portion. The first connecting portion connects the conductive portion and the flat portion. The second connecting portion connects the conductive portion and the flat portion. The flat portion, the first connecting portion, the second connecting portion, and the conductive portion form a ring.

[0014] Understandably, on the one hand, since the flat portion, the first connecting portion, the second connecting portion, and the conductive portion can form a ring, the conductive portion is part of the ring structure; a single conductive portion cannot form a ring structure. Thus, when the conductive portion transmits a signal, it is less likely to form a ring current, which is beneficial for signal transmission. On the other hand, the flat portion, the first connecting portion, the second connecting portion, and the conductive portion can form a complete plane, resulting in a high degree of flatness in the first sub-layer.

[0015] In one feasible implementation, the first sublayer does not include a flat portion, a first connecting portion, or a second connecting portion. The conductive portion has a ring-shaped structure. It is understood that the conductive portion can form a complete plane, resulting in a high degree of flatness in the first sublayer.

[0016] In one feasible embodiment, both the first and second connecting portions are made of insulating material. The flat portion is made of conductive material. The flat portion is grounded.

[0017] Understandably, on the one hand, both the flat portion and the conductive portion are made of conductive materials. In this case, it is easy to use the same material for both the flat portion and the conductive portion, which can reduce the types of materials and lower the cost, and also make the hardness of the flat portion and the conductive portion compatible, thereby improving the hardness uniformity of the first sublayer.

[0018] In addition, by grounding the flat section, the pulse width modulation (PWM) signal is less likely to be electromagnetically coupled in the flat section, and the flat section is less likely to affect the normal operation of other components.

[0019] In one possible implementation, the image stabilization motor also includes a substrate. A first sublayer is fixed to the substrate by an insulating adhesive layer. The substrate is grounded. The image stabilization motor also includes a conductive element. The conductive element connects the flat portion to the substrate.

[0020] It is understandable that the flat portion can be grounded through structures such as conductive components and substrates. This method is relatively simple and easy to implement.

[0021] In one feasible approach, the conductive element is a solder joint.

[0022] Understandably, this solution connects the planar portion to the substrate using welding processes (such as laser welding or brazing). In this case, the solder joint formed between the planar portion and the substrate is a conductive element. The connection method between the planar portion and the substrate is relatively simple and easy to implement. Furthermore, the connection stability between the planar portion and the substrate is relatively reliable.

[0023] In one feasible implementation, the flat portion, the first connecting portion, and the second connecting portion are all made of insulating material. This prevents electromagnetic coupling of the PWM signal within the flat portion, thus minimizing the impact of the flat portion on the normal operation of other components.

[0024] In one feasible implementation, the flat portion, the first connecting portion, and the second connecting portion are all made of conductive materials. This prevents the PWM signal from easily undergoing electromagnetic coupling in the flat portion, thus minimizing the impact of the flat portion on the normal operation of other components.

[0025] In one possible embodiment, the electrode assembly further includes a first electrode sheet and a second electrode sheet spaced apart. The first and second electrode sheets are also spaced apart from the driving electrode and the common electrode. The first and second electrode sheets are located between a second conductive sheet and a fourth conductive sheet.

[0026] The first electrode is used to transmit serial data (SDA) signals of the internal integrated circuit (I2C) bus to the lens motor. The second electrode is used to transmit the serial clock (SCL) signal of the I2C signal to the lens motor.

[0027] It is understandable that setting a first electrode plate and a second electrode plate in the electrode assembly can improve the integration of the image stabilization motor, thereby simplifying the way the lens motor is electrically connected to external devices. As a result, when the image stabilization motor is used in the camera module, the structure of the camera module is relatively simple.

[0028] In addition, by grounding the flat portion, the PWM signal is less likely to undergo electromagnetic coupling in the flat portion, and the flat portion is less likely to affect the normal operation of the first electrode plate and the second electrode plate.

[0029] In one feasible embodiment, the common electrode includes a third conductive sheet and a fourth conductive sheet disposed opposite to and spaced apart from each other. The third and fourth conductive sheets are located between the first and second conductive sheets. The first, second, third, and fourth conductive sheets enclose a light-transmitting area.

[0030] Understandably, when the first and second conductive sheets are located on opposite sides of the light-transmitting area, the distance between them is relatively large, making it more difficult to connect them. The bridging component in this implementation can also connect the distant first and second conductive sheets, thus solving the problem of their difficult connection.

[0031] Additionally, the reed includes a main body, a first spring arm, and a second spring arm. The first and second spring arms are respectively connected to opposite sides of the main body. The first spring arm is elastically connected to a third conductive sheet. The second spring arm is elastically connected to a fourth conductive sheet. The main body and the electrode assembly are spaced apart.

[0032] It is understandable that by setting a first spring arm elastically connected to the third conductive sheet, a second spring arm elastically connected to the fourth conductive sheet, and spacing the main body and electrode assembly apart, the main body of the reed can move to any position relative to the electrode assembly when a force is applied to it. When the main body of the reed is used to fix the lens of the camera module, because the main body of the reed can move to any position relative to the electrode assembly, it can drive the lens to move to any position relative to the electrode assembly, thus enabling optical image stabilization of the camera module's lens.

[0033] In one possible implementation, the driving electrode further includes an electrode W1, which is spaced apart from both the first and second conductive sheets. The electrode W1 is located between the first and fourth conductive sheets. The SMA line also includes a fourth SMA line, one end of which is connected to a reed, and the other end of which is connected to the electrode W1. The common electrode, the reed, the fourth SMA line, and the electrode W1 form a partial current loop.

[0034] Understandably, when a signal is applied to the current loop formed by the common electrode, the reed, the fourth SMA line, and the W1 electrode, the fourth SMA line is energized and heated, causing it to contract and thus generating a corresponding tension on the reed. The reed can move to any position relative to the electrode assembly. When the reed is used to fix the lens of the camera module, because the reed can move to any position relative to the electrode assembly, it can drive the lens to move to any position relative to the electrode assembly, enabling the lens of the camera module to achieve optical image stabilization.

[0035] In one possible implementation, the driving electrode further includes a W2 electrode. The W2 electrode is spaced apart from both the first and second conductive sheets. The W2 electrode is located on one side of the first and second conductive sheets. A portion of the W2 electrode is located between the third and fourth conductive sheets, and the W2 electrode is positioned closer to the third conductive sheet than the fourth conductive sheet. The SMA line also includes a second SMA line. One end of the second SMA line is connected to a reed, and the other end is connected to the W2 electrode. The common electrode, the reed, the second SMA line, and the W2 electrode form a partial current loop.

[0036] Understandably, when a signal is applied to the common electrode, the reed, the second SMA line, and the W2 electrode, the second SMA line is energized and heated, causing it to contract and thus generating a corresponding tension on the reed. The reed can move to any position relative to the electrode assembly. When the reed is used to fix the lens of the camera module, because the reed can move to any position relative to the electrode assembly, it can drive the lens to move to any position relative to the electrode assembly, enabling the lens of the camera module to achieve optical image stabilization.

[0037] In one possible implementation, the driving electrode further includes a W3 electrode. The W3 electrode is spaced apart from the first and second conductive sheets. The W3 electrode is located between the first and fourth conductive sheets. The SMA line also includes a third SMA line. One end of the third SMA line is connected to a reed, and the other end is connected to the W3 electrode. The common electrode, the reed, the third SMA line, and the W3 electrode form a partial current loop.

[0038] Understandably, when a signal is applied to the common electrode, the reed, the third SMA line, and the W3 electrode, the third SMA line is energized and heated, causing it to contract and thus generating a corresponding tension on the reed. The reed can move to any position relative to the electrode assembly. When the reed is used to fix the lens of the camera module, because the reed can move to any position relative to the electrode assembly, it can drive the lens to move to any position relative to the electrode assembly, enabling the lens of the camera module to achieve optical image stabilization.

[0039] In one possible embodiment, the electrode assembly further includes a third electrode and a fourth electrode spaced apart. The third and fourth electrode plates are also spaced apart from the drive electrode and the common electrode. The third and fourth electrode plates are located on the side of the third conductive sheet away from the light-transmitting area. The third electrode plate is used to provide a positive terminal for power to the lens motor. The fourth electrode plate is used to provide a negative terminal for power to the lens motor.

[0040] It is understandable that setting a third and fourth electrode plate in the electrode assembly can improve the integration of the image stabilization motor, thereby simplifying the way the lens motor is electrically connected to external devices. Consequently, when the image stabilization motor is used in the camera module, the structure of the camera module is relatively simple.

[0041] Secondly, embodiments of this application provide a camera module. The camera module includes a lens and the aforementioned image stabilization motor. The lens is fixed to a spring of the image stabilization motor.

[0042] Understandably, when the structure of the image stabilization motor is relatively simple, the complexity of the camera module structure can also be reduced significantly. Furthermore, when the size of the image stabilization motor can be significantly reduced, the size of the camera module can also be significantly reduced, which facilitates miniaturization of the camera module.

[0043] In addition, when the lens is fixed to the reed, since the reed can move to any position relative to the electrode assembly, the reed can drive the lens to move to any position relative to the electrode assembly, thus enabling the lens of the camera module to achieve optical image stabilization.

[0044] In one possible implementation, the camera module further includes a module circuit board, a photosensitive chip, a bracket, and a light filter. The photosensitive chip is fixed to and electrically connected to the module circuit board. The bracket is fixed to the module circuit board. The light filter is fixed to the bracket and positioned opposite to the photosensitive chip. The image stabilization motor is fixed to the bracket. The first conductive plate of the image stabilization motor and the common electrode of the electrode assembly are both electrically connected to the module circuit board.

[0045] It is understandable that the module circuit board, common electrode, spring, first SMA line, first conductive sheet, second conductive sheet, and bridging component form a partial current loop. At this time, the module circuit board can transmit signals to the first SMA line.

[0046] In one possible implementation, the camera module also includes a lens motor. The lens motor is fixed to the image stabilization motor. The lens is fixed to the lens motor. The lens motor is used to drive the lens to move along the optical axis of the camera module.

[0047] Understandably, the camera module can achieve both autofocus and optical image stabilization. Its rich functionality better meets user needs.

[0048] In one possible implementation, the lens motor includes a base, a lower spring, an upper spring, a movable bracket, a first coil, a first magnet, and a motor bracket. The base includes a subbase and multiple positioning posts. The multiple positioning posts are fixed to the subbase. Each positioning post has a first stepped surface and a second stepped surface spaced apart. The subbase is fixed to the spring of the image stabilization motor. The lower spring includes a first ring body and multiple spaced-apart first connecting feet. The first connecting feet are connected to the periphery of the first ring body. The multiple first connecting feet are fixed one-to-one with the multiple first stepped surfaces. The upper spring includes a second ring body and multiple spaced-apart second connecting feet. The second connecting feet are connected to the periphery of the second ring body. The multiple second connecting feet are fixed one-to-one with the multiple second stepped surfaces.

[0049] A movable support is connected between the first ring and the second ring. A first coil is fixed to the movable support. The lens is fixed to the movable support. The motor support is fixed to the bridging layer of the image stabilization motor. A first magnet is fixed to the inner side of the motor support and is positioned opposite to the first coil.

[0050] Thirdly, embodiments of this application provide a camera module. The camera module includes a module circuit board, a stabilization motor, and a housing. The housing is fixed to the module circuit board. The housing is grounded through the module circuit board. The stabilization motor is fixed to the module circuit board and located inside the housing.

[0051] The image stabilization motor includes a bridging layer, electrode assemblies, reeds, and multiple SMA wires. The electrode assemblies are stacked on one side of the bridging layer. The reeds are located on the side of the electrode assemblies away from the bridging layer. Multiple SMA wires are arranged around the reeds. One end of each SMA wire is connected to the reed, and the other end is connected to the electrode assembly.

[0052] The electrode assembly includes a common electrode and a drive electrode spaced apart. A reed contacts the common electrode. The drive electrode includes a first conductive sheet and a second conductive sheet spaced apart. The common electrode and the first conductive sheet are connected to the module circuit board.

[0053] The bridging layer comprises a first sublayer and a second sublayer stacked together. Electrode assemblies are stacked on the second sublayer.

[0054] The first sublayer includes a conductive portion, a planar portion, a first connecting portion, and a second connecting portion. The planar portion is disposed opposite to the conductive portion. The first connecting portion connects the conductive portion and the planar portion. The second connecting portion connects the conductive portion and the planar portion. The planar portion, the first connecting portion, the second connecting portion, and the conductive portion form a ring. The first connecting portion and the second connecting portion are both made of insulating material. The planar portion is made of conductive material.

[0055] The second sublayer includes an adhesive portion and a first conductive post and a second conductive post spaced apart. The adhesive portion is made of an insulating material. The adhesive portion is stacked on top of the conductive portion. Electrode assemblies are stacked on the adhesive portion. Both the first and second conductive posts are embedded in the adhesive portion. The first conductive post connects the conductive portion to the first conductive sheet. The second conductive post connects the conductive portion to the second conductive sheet.

[0056] The SMA line includes a first SMA line. One end of the first SMA line is connected to a spring, and the other end is connected to a second conductive sheet. The module circuit board, the common electrode of the electrode assembly, the spring, the first SMA line, the first conductive sheet, the second conductive sheet, the first conductive post, the second conductive post, and the conductive part form a partial current loop.

[0057] The anti-shake motor also includes conductive components. These components connect the flat portion to the housing.

[0058] It is understandable that by providing a bridging layer on one side of the electrode assembly, and using the first conductive post, the second conductive post, and the conductive part of the bridging layer to connect the first conductive sheet and the second conductive sheet of the driving electrode, on the one hand, in the compact structure of the electrode assembly, the problem of the first conductive sheet and the second conductive sheet being difficult to connect when set apart can be solved, that is, the positional constraints of the first conductive sheet and the second conductive sheet can be released; on the other hand, the surrounding area of ​​the driving electrode layer does not need to be arranged with many leads to meet the electrical connection requirements. In this way, the arrangement of the driving electrodes on the electrode assembly is more regular, and the structure of the anti-shake motor is relatively simple.

[0059] Furthermore, compared to the approach of arranging leads around the driving electrode layer, this approach, although adding a bridging layer to the thickness of the stabilization motor, allows for a significantly smaller bridging layer. In this case, the volume of the bridging layer is negligible compared to the overall volume of the stabilization motor. Therefore, the size of the stabilization motor in this approach can be greatly reduced, meaning the stabilization motor can be miniaturized.

[0060] Furthermore, when a signal is applied to the current loop formed by the module circuit board, the common electrode of the electrode assembly, the reed, the first SMA line, the first conductive sheet, the second conductive sheet, the first conductive post, the second conductive post, and the conductive part, the first SMA line is energized and heated, causing it to contract and thus generating a corresponding pulling force on the reed. The reed can move to any position relative to the electrode assembly. When the reed is used to fix the lens of the camera module, because the reed can move to any position relative to the electrode assembly, the reed can drive the lens to move to any position relative to the electrode assembly, enabling the lens of the camera module to achieve optical image stabilization.

[0061] Furthermore, by grounding the flat section through the housing, the PWM signal is less likely to undergo electromagnetic coupling within the flat section, thus reducing the likelihood of the flat section interfering with the normal operation of other components. Additionally, the flat section can be grounded through conductive components and the housing. This method is relatively simple and easy to implement.

[0062] In one feasible approach, the conductive element is a solder joint.

[0063] Understandably, this solution connects the flat portion to the outer casing using welding processes (such as laser welding or brazing). In this case, the weld joint formed between the flat portion and the outer casing is a conductive element. The connection method between the flat portion and the outer casing is relatively simple and easy to implement. Furthermore, the connection stability between the flat portion and the outer casing is relatively reliable.

[0064] In one possible embodiment, the electrode assembly further includes a first electrode sheet and a second electrode sheet spaced apart. The first and second electrode sheets are also spaced apart from the driving electrode and the common electrode. The first and second electrode sheets are located between a second conductive sheet and a fourth conductive sheet.

[0065] The first electrode is used to transmit serial data (SDA) signals of the internal integrated circuit (I2C) bus to the lens motor. The second electrode is used to transmit the serial clock (SCL) signal of the I2C signal to the lens motor.

[0066] It is understandable that setting a first electrode plate and a second electrode plate in the electrode assembly can improve the integration of the image stabilization motor, thereby simplifying the way the lens motor is electrically connected to external devices. As a result, when the image stabilization motor is used in the camera module, the structure of the camera module is relatively simple.

[0067] In addition, the flat part of this solution is grounded through the outer casing, so the PWM signal is less likely to be electromagnetically coupled in the flat part, and the flat part is less likely to affect the normal operation of the first electrode plate and the second electrode plate.

[0068] In one feasible embodiment, the common electrode includes a third conductive sheet and a fourth conductive sheet disposed opposite to and spaced apart from each other. The third and fourth conductive sheets are located between the first and second conductive sheets. The first, second, third, and fourth conductive sheets enclose a light-transmitting area.

[0069] Understandably, when the first and second conductive sheets are located on opposite sides of the light-transmitting area, the distance between them is relatively large, making it more difficult to connect them. The bridging component in this implementation can also connect the distant first and second conductive sheets, thus solving the problem of their difficult connection.

[0070] Additionally, the reed includes a main body, a first spring arm, and a second spring arm. The first and second spring arms are respectively connected to opposite sides of the main body. The first spring arm is elastically connected to a third conductive sheet. The second spring arm is elastically connected to a fourth conductive sheet. The main body and the electrode assembly are spaced apart.

[0071] It is understandable that by setting a first spring arm elastically connected to the third conductive sheet, a second spring arm elastically connected to the fourth conductive sheet, and spacing the main body and electrode assembly apart, the main body of the reed can move to any position relative to the electrode assembly when a force is applied to it. When the main body of the reed is used to fix the lens of the camera module, because the main body of the reed can move to any position relative to the electrode assembly, it can drive the lens to move to any position relative to the electrode assembly, thus enabling optical image stabilization of the camera module's lens.

[0072] In one possible embodiment, the electrode assembly further includes a third electrode and a fourth electrode spaced apart. The third and fourth electrode plates are also spaced apart from the drive electrode and the common electrode. The third and fourth electrode plates are located on the side of the third conductive sheet away from the light-transmitting area. The third electrode plate is used to provide a positive terminal for power to the lens motor. The fourth electrode plate is used to provide a negative terminal for power to the lens motor.

[0073] It is understandable that setting a third and fourth electrode plate in the electrode assembly can improve the integration of the image stabilization motor, thereby simplifying the way the lens motor is electrically connected to external devices. Consequently, when the image stabilization motor is used in the camera module, the structure of the camera module is relatively simple.

[0074] Fourthly, embodiments of this application provide an electronic device. The electronic device includes a housing and a camera module as described above. The camera module is disposed within the housing.

[0075] Understandably, when the structure of the camera module is relatively simple, the complexity of the electronic device's structure can also be reduced to a greater extent. Attached Figure Description

The electronic device 100 includes a housing 10, a screen 20, a main circuit board 30, and a camera module 40. It should be noted that... Figure 1 , Figure 2 The accompanying drawings below only schematically illustrate some components included in the electronic device 100; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 , Figure 2 As defined in the accompanying drawings below. Furthermore, since the main circuit board 30 and the camera module 40 are internal structures of the electronic device 100, Figure 1 The main circuit board 30 and the camera module 40 are schematically shown by dashed lines. In other embodiments, when the electronic device 100 is a device of some other form, the electronic device 100 may not include the screen 20 and the main circuit board 30.

[0108] Exemplarily, the housing 10 includes a frame 11 and a back cover 12. The back cover 12 is fixedly connected to one side of the frame 11. The screen 20 is fixed to the side of the frame 11 away from the back cover 12. The screen 20, the frame 11, and the back cover 12 together enclose the interior of the electronic device 100. The interior of the electronic device 100 can be used to house components of the electronic device 100, such as a battery, receiver, or microphone. The screen 20 can be used to display images, etc. The screen 20 can be a flat screen or a curved screen. The display of the screen 20 can be an organic light-emitting diode (OLED) display, or an active-matrix organic light-emitting diode (AMOLED) display, or a liquid crystal display (LCD), etc.

[0109] Please refer to it again. Figure 1 and Figure 2 The main circuit board 30 is fixed inside the electronic device 100. The main circuit board 30 may be equipped with chips such as a central processing unit (CPU), a graphics processing unit (GPU), or universal flash storage (UFS).

[0110] Additionally, the camera module 40 is located inside the electronic device 100. The camera module 40 can be used to capture ambient light from outside the electronic device 100. The camera module 40 can be a rear-facing camera module or a front-facing camera module. Figure 2 The illustrated ordinary camera module (with the optical axis of the camera module oriented in the thickness direction of the electronic device 100) can also be a periscope camera module (for example, with the optical axis of the camera module oriented in the width direction of the electronic device 100). Furthermore, the camera module 40 is electrically connected to the host circuit board 30. In this way, signals can be transmitted between the camera module 40 and the host circuit board 30.

[0111] For example, the back cover 12 is provided with a light-transmitting hole 13. The light-transmitting hole 13 penetrates two opposite surfaces of the back cover 12. In addition, the electronic device 100 also includes a camera trim 53 and a cover plate 52. The cover plate 52 is fixedly connected to the inner surface of the camera trim 53. A portion of the camera trim 53 is fixed to the inner surface of the back cover 12. A portion of the camera trim 53 contacts the wall of the light-transmitting hole 13. The camera trim 53 and the cover plate 52 separate the interior of the electronic device 100 from the exterior of the electronic device 100. The camera trim 53 and the cover plate 52 prevent water or dust from entering the interior of the electronic device 100 through the light-transmitting hole 13. Furthermore, the cover plate 52 is made of a transparent material (e.g., glass or plastic). Ambient light from outside the electronic device 100 can pass through the cover plate 52 and enter the interior of the electronic device 100. The camera module 40 collects the ambient light entering the interior of the electronic device 100.

[0112] Please see Figure 3 and Figure 4 , Figure 3 yes Figure 1 A schematic diagram of the camera module 40 of the electronic device 100 shown. Figure 4 yes Figure 3 The diagram shows a partial exploded view of the camera module 40. The camera module 40 includes a module circuit board 41, a stabilization motor 42, a lens assembly 43, a photosensitive chip 44, a bracket 450, a filter 460, and a housing 470. The photosensitive chip 44, also known as an image sensor or photosensitive element, is used to collect ambient light and convert the image information carried by the ambient light into electrical signals.

[0113] Please see Figure 5 and combined Figure 4 As shown, Figure 5 yes Figure 3 The diagram shows a partial cross-sectional view of the camera module 40 at the BB line. The photosensitive chip 44 is fixed to and electrically connected to the module circuit board 41. At this time, the photosensitive chip 44 and the module circuit board 41 can transmit signals to each other.

[0114] Additionally, the bracket 450 is fixed to the module circuit board 41. The bracket 450 and the photosensitive chip 44 are located on the same side of the module circuit board 41. The bracket 450 has a light-transmitting hole 4501. The filter 460 is fixed to the bracket 450 and located within the light-transmitting hole 4501. The filter 460 is also disposed opposite to the photosensitive chip 44. The filter 460 can be used to filter infrared light or blue light from ambient light, thereby ensuring that the photosensitive chip 44 has better imaging quality. In other embodiments, when the camera module 40 has other structures, the arrangement of the bracket 450 and the filter 460 can be flexibly configured according to requirements. Furthermore, in some camera module structures, the camera module may not include the bracket 450 and the filter 460.

[0115] Additionally, the image stabilization motor 42 is fixed to the side of the bracket 450 away from the module circuit board 41. The image stabilization motor 42 is used for optical image stabilization (OIS). The image stabilization motor 42 can be electrically connected to the module circuit board 41. In this case, the module circuit board 41 can transmit signals to the image stabilization motor 42.

[0116] Please refer to it again. Figure 5 and combined Figure 4 As shown, the lens assembly 43 includes a lens motor 431 and a lens 432.

[0117] The lens 432 is mounted on the lens motor 431. The lens motor 431 is used to drive the lens 432 to move along the optical axis of the camera module 40 to achieve autofocus (AF).

[0118] In this embodiment, the lens motor 431 is electrically connected to the image stabilization motor 42. The module circuit board 41 can transmit signals to the lens motor 431 via the image stabilization motor 42. For example, the module circuit board 41 can transmit an internal integrated circuit (I2C) signal to the lens motor 431 via the image stabilization motor 42. In this case, the lens motor 431 can control the lens 432 to move along the optical axis of the camera module 40 according to the I2C signal to achieve autofocus. The module circuit board 41 can also transmit power to the lens motor 431 via the image stabilization motor 42 to enable the lens motor 431 to operate.

[0119] Additionally, the lens 432 is also fixed to the side of the image stabilization motor 42 away from the module circuit board 41. It should be noted that the connection method between the lens 432 and the image stabilization motor 42 will be described in detail below with reference to the accompanying drawings. It will not be repeated here. The image stabilization motor 42 is used to drive the lens 432 to move in a plane perpendicular to the optical axis of the lens 432 to achieve optical image stabilization. For example, when the electronic device 100 shakes due to external forces, the image stabilization motor 42 can adjust the position of the lens 432 to avoid or reduce positional shift of the lens 432 caused by shaking, thereby improving the imaging quality of the camera module 40.

[0120] Please refer to it again. Figure 5 and combined Figure 4 As shown, the housing 470 is fixed to the module circuit board 41. The housing 470 has a through hole 4701. Part of the lens 432 extends out of the housing 470 through the through hole 4701. Exemplarily, the housing 470 can be grounded. For example, the housing 470 can be electrically connected to the ground point of the module circuit board 41. In this way, the housing 470 can shield electromagnetic waves outside the housing 470 to prevent external electromagnetic waves from interfering with the operation of the image stabilization motor 42 and the lens motor 431.

[0121] In other embodiments, the housing 470 may also be fixed to the bracket 450.

[0122] Combination Figure 2 As shown, the module circuit board 41 is fixed inside the electronic device 100. The lens 432 faces the cover plate 52 to receive ambient light passing through the cover plate 52. The module circuit board 41 can be electrically connected to the host circuit board 30. In this way, the module circuit board 41 and the host circuit board 30 can transmit signals to each other.

[0123] Please see Figure 6 , Figure 6 yes Figure 4 The image shows a partially exploded view of the lens assembly 43. The lens motor 431 includes a base 4311, a lower spring 4312, an upper spring 4313, a movable bracket 4314, a first coil 4315, a first magnet 4316, a second coil 4317, a second magnet 4318, and a motor bracket 4319.

[0124] The base 4311 includes a base 4341 and positioning posts 4342 fixedly connected to one side of the base 4341. Exemplarily, there are four positioning posts 4342. The four positioning posts 4342 are respectively located at the four corners of the base 4341.

[0125] The lower spring 4312 includes a first ring body 4351 and a plurality of spaced-apart first connecting feet 4352. The first connecting feet 4352 are connected to the periphery of the first ring body 4351. For example, the number of first connecting feet 4352 is four.

[0126] Furthermore, the upper spring 4313 includes a second ring body 4361 and a plurality of spaced-apart second connecting feet 4362. The second connecting feet 4362 are connected to the periphery of the second ring body 4361. Exemplarily, the number of second connecting feet 4362 is four.

[0127] Please see Figure 7 and combined Figure 6 As shown, Figure 7 yes Figure 4 The diagram shows a partial structural schematic of the lens assembly 43. Each positioning post 4342 has a first stepped surface 4343 and a second stepped surface 4344 spaced apart. In other words, the first stepped surface 4343 and the second stepped surface 4344 have a height difference along the length of the positioning post 4342.

[0128] Multiple first connecting feet 4352 are fixed to multiple first step surfaces 4343 respectively. The first ring body 4351 is located in the area enclosed by multiple positioning posts 4342.

[0129] Please see Figure 8 and combined Figure 6 and Figure 7 As shown, Figure 8 yes Figure 4 The diagram shows a partial structural schematic of the lens assembly 43. Multiple second connecting feet 4362 are fixed one-to-one with multiple second step surfaces 4344. The second ring body 4361 is located within the area enclosed by multiple positioning posts 4342.

[0130] Additionally, the movable bracket 4314 is connected between the first ring body 4351 and the second ring body 4361. It should be understood that, since the lower spring 4312 and the upper spring 4313 are elastic, when a force is applied to the movable bracket 4314, the movable bracket 4314 can overcome the elastic force of the lower spring 4312 and the upper spring 4313 and move up and down.

[0131] Additionally, the first coil 4315 and the second coil 4317 are fixed to the movable bracket 4314. The first coil 4315 and the second coil 4317 are arranged opposite to each other. The lens 432 is fixed to the movable bracket 4314.

[0132] Please refer to it again. Figure 5 and combined Figure 8As shown, the base 4311 is fixed to the image stabilization motor 42. At this time, the lens 432 is fixedly connected to the image stabilization motor 42 via the base 4311. The motor bracket 4319 is fixed to the image stabilization motor 42. Part of the lens 432 passes through the motor bracket 4319 and extends out of the motor bracket 4319.

[0133] Additionally, the first magnet 4316 and the second magnet 4318 are fixed to the motor bracket 4319. The first magnet 4316 is disposed opposite to the first coil 4315. The second magnet 4318 is disposed opposite to the second coil 4317. It is understood that when a signal is applied to the second magnet 4318 and the second coil 4317, the first magnet 4316 can cooperate with the first coil 4315, and the second magnet 4318 can cooperate with the second coil 4317 to push the movable bracket 4314 to move along the optical axis of the camera module 40, thereby pushing the lens 432 to move along the optical axis of the camera module 40.

[0134] In other embodiments, when the lens motor 431 has a different structure, the lens 432 can also be directly fixedly connected to the image stabilization motor 42.

[0135] Please see Figure 9 , Figure 9 yes Figure 4 The diagram shows a partially exploded view of the image stabilization motor 42. The image stabilization motor 42 includes a substrate 421, a first adhesive layer 422, a bridging layer 423, an electrode assembly 424, a spring 425, and SMA lines 426. The SMA lines 426 are made of shape memory alloys (SMA), such as nickel-titanium alloy. SMA is a general term for a class of metals with shape memory effects. In this embodiment, there are four SMA lines 426. The SMA lines 426 include a first SMA line 4264, a second SMA line 4262, a third SMA line 4263, and a fourth SMA line 4261. In other embodiments, the number of SMA lines 426 is not specifically limited.

[0136] The substrate 421 is annular. The substrate 421 includes an upper surface 4211 and a lower surface 4212 disposed opposite to each other. The substrate 421 can be made of metal, such as steel plate. This provides the substrate 421 with good hardness. Exemplarily, the substrate 421 has a first through hole 4213 and a second through hole 4214 spaced apart. Both the first through hole 4213 and the second through hole 4214 penetrate the upper surface 4211 and the lower surface 4212 of the substrate 421. The first through hole 4213 and the second through hole 4214 are located on both sides of the substrate 421.

[0137] Please see Figure 10 and combined Figure 9 As shown, Figure 10yes Figure 4 The diagram shows a partial structural schematic of the anti-shake motor 42. The first adhesive layer 422 is annular. The first adhesive layer 422 is fixed to the upper surface 4211 of the substrate 421. The first adhesive layer 422 may partially or completely cover the upper surface 4211 of the substrate 421. The first adhesive layer 422 avoids the first through-hole 4213 and the second through-hole 4214 of the substrate 421. The first adhesive layer 422 is made of insulating material.

[0138] Please see Figure 11 and combined Figure 9 As shown, Figure 11 yes Figure 9 The diagram shows an exploded view of the bridging layer 423. The bridging layer 423 is annular. It includes a first sublayer 4231 and a second sublayer 4232 stacked together. Both the first sublayer 4231 and the second sublayer 4232 are annular. Furthermore, the first sublayer 4231 includes a conductive portion 4233, a first connecting portion 4234, a planar portion 4235, and a second connecting portion 4236.

[0139] Please see Figure 12 and combined Figure 11 As shown, Figure 12 yes Figure 4 The diagram shows a partial structural representation of the anti-shake motor 42. The conductive portion 4233, the first connecting portion 4234, the flat portion 4235, and the second connecting portion 4236 are connected sequentially. The conductive portion 4233 and the flat portion 4235 are positioned opposite each other. The second connecting portion 4236 is also connected to the end of the conductive portion 4233 away from the first connecting portion 4234. Furthermore, the conductive portion 4233, the first connecting portion 4234, the flat portion 4235, and the second connecting portion 4236 are fixed to the surface of the first adhesive layer 422 away from the substrate 421. Since the first adhesive layer 422 is an insulating material, the conductive portion 4233 and the substrate 421 can be insulated from each other.

[0140] In this embodiment, the conductive portion 4233 is part of a ring-shaped structure, but it is not a continuous ring. The conductive portion 4233 can be arc-shaped, strip-shaped, etc. It should be understood that when the first sub-layer 4231 only includes the conductive portion 4233, that is, it does not include the first connecting portion 4234, the flat portion 4235, and the second connecting portion 4236, the conductive portion 4233 is arc-shaped and cannot completely cover the first adhesive layer 422 in a ring shape. As a result, the flatness of the first sub-layer 4231 is poor, which is not conducive to the high-precision setting of the anti-shake motor 42. In this embodiment, by sequentially connecting the first connecting portion 4234, the flat portion 4235, and the second connecting portion 4236 to the conductive portion 4233, the conductive portion 4233, the first connecting portion 4234, the flat portion 4235, and the second connecting portion 4236 form a ring, thereby achieving a ring-shaped coverage of the first adhesive layer 422, which significantly improves the flatness of the first sublayer 4231.

[0141] Furthermore, both the first connecting portion 4234 and the second connecting portion 4236 can be made of insulating materials. For example, the first connecting portion 4234 and the second connecting portion 4236 can be formed by curing insulating adhesive. In this case, while the flat portion 4235 improves the flatness of the first sublayer 4231, the flat portion 4235 and the conductive portion 4233 can be insulated from each other through the first connecting portion 4234 and the second connecting portion 4236, so that the conductive portion 4233 will not form a continuous ring structure due to the presence of the flat portion 4235.

[0142] In other embodiments, the first sublayer 4231 may also omit the first connecting portion 4234, the second connecting portion 4236, or the flat portion 4235.

[0143] In other embodiments, when the first sublayer 4231 does not include the first connecting portion 4234, the second connecting portion 4236, or the flat portion 4235, the conductive portion 4233 can also be directly formed into a ring structure.

[0144] For example, the material of the flat portion 4235 is the same as the material of the conductive portion 4233. For instance, both the flat portion 4235 and the conductive portion 4233 can be made of metal. The metal material can be copper, gold, silver, or aluminum, etc. In this way, on the one hand, the cost of the first sublayer 4231 will not significantly increase due to the increase in the type of material; on the other hand, the hardness of the flat portion 4235 is relatively consistent with the hardness of the conductive portion 4233, which can ensure that the first sublayer 4231 has better uniformity. In other embodiments, the material of the flat portion 4235 can also be other conductive materials, but it can be different from the conductive material of the conductive portion 4233. Furthermore, the material of the flat portion 4235 can also be an insulating material.

[0145] Please refer to it again. Figure 11 The second sublayer 4232 includes an adhesive portion 4237, a first conductive post 4238, and a second conductive post 4239. The adhesive portion 4237 is annular. The adhesive portion 4237 includes an upper surface 4271 and a lower surface 4272 disposed opposite to each other. The adhesive portion 4237 is made of an insulating material. The first conductive post 4238 and the second conductive post 4239 are both made of conductive materials.

[0146] For example, the adhesive portion 4237 can be integrally formed with the first connecting portion 4234 and the second connecting portion 4236.

[0147] Please see Figure 13 and combined Figure 12 As shown, Figure 13 yes Figure 9 The diagram shows a cross-sectional view of the bridging layer at the CC line. It should be noted that... Figure 13 The diagram illustrates a structure enclosed by two small dashed circles and another by two large dashed circles. The larger dashed circles are enlarged versions of the smaller ones. When the same diagram appears in the accompanying figures, its meaning is the same as... Figure 13 Same. This will not be repeated below.

[0148] In this configuration, the adhesive portion 4237 is fixed to the surface of the first sublayer 4231 away from the first adhesive layer 422. The adhesive portion 4237 covers the conductive portion 4233, the first connecting portion 4234, the flat portion 4235, and the second connecting portion 4236 of the first sublayer 4231 to improve the flatness of the second sublayer 4232. At this time, the upper surface 4271 of the adhesive portion 4237 faces away from the first sublayer 4231, and the lower surface 4272 of the adhesive portion 4237 faces the first sublayer 4231.

[0149] Furthermore, the first conductive post 4238 and the second conductive post 4239 are both embedded in the adhesive portion 4237 at intervals. The first conductive post 4238 and the second conductive post 4239 are located on opposite sides of the adhesive portion 4237. One end of each of the first conductive post 4238 and the second conductive post 4239 is exposed relative to the upper surface 4271 of the adhesive portion 4237 and connected to the conductive portion 4233 of the first sub-layer 4231. The other end of each of the first conductive post 4238 and the second conductive post 4239 is also exposed relative to the lower surface 4272 of the adhesive portion 4237 and connected to the conductive portion 4233 of the first sub-layer 4231. In this way, the first conductive post 4238 and the second conductive post 4239 can be electrically connected through the conductive portion 4233. At this time, the first conductive post 4238, the second conductive post 4239, and the conductive portion 4233 form a bridging member 4230. For example, the bridging member 4230 can be a "U" shaped structure. In other embodiments, the bridging member 4230 may also be of other shapes.

[0150] Please see Figure 14 , Figure 14 yes Figure 9 An enlarged schematic diagram of the electrode assembly 424 is shown. The electrode assembly 424 is annular. Exemplarily, the electrode assembly 424 has an "inner circle, outer square" structure. The electrode assembly 424 has a light-transmitting region 490. The light-transmitting region 490 is used to allow ambient light passing through the lens 432 to pass through the electrode assembly 424.

[0151] Electrode assembly 424 includes a first side 1 and a second side 2 disposed opposite to each other, and a third side 3 and a fourth side 4 disposed opposite to each other. The first side 1 and the second side 2 are connected between the third side 3 and the fourth side 4. The first side 1, the second side 2, the third side 3, and the fourth side 4 enclose a light-transmitting area 490. Furthermore, the connection between the first side 1 and the fourth side 4 forms a first corner 5 of the electrode assembly 424. The connection between the first side 1 and the third side 3 forms a second corner 6 of the electrode assembly 424. The connection between the second side 2 and the third side 3 forms a third corner 7 of the electrode assembly 424. The connection between the second side 2 and the fourth side 4 forms a fourth corner 8 of the electrode assembly 424.

[0152] In this embodiment, the electrode assembly 424 includes a first type of electrode 4241, a second type of electrode 4242, a third type of electrode 4243, and a fourth type of electrode 4244 spaced apart. Exemplarily, the first type of electrode 4241 may be the drive electrode (also called the wire electrode or W electrode) of the image stabilization motor 42. The second type of electrode 4242 may be the common electrode (also called the COM electrode or Opin electrode) of the image stabilization motor 42. The third type of electrode 4243 may be electrically connected to the lens motor 431 for supplying power to the lens motor 431 (see [link to documentation]). Figure 5 The third type electrode 4243 can be electrically connected to the lens motor 431 via a flexible printed circuit (FPC), wires, etc. The fourth type electrode 4244 can be electrically connected to the lens motor 431 to provide I2C signals. Figure 5 Power is transmitted. Exemplarily, the fourth type electrode 4244 can be electrically connected to the lens motor 431 via a flexible printed circuit (FPC), wires, etc. In other embodiments, the electrode assembly 424 may not include the third type electrode 4243 and the fourth type electrode 4244.

[0153] The first type of electrode 4241 includes W0 electrode 45, W1 electrode 46, W2 electrode 47 and W3 electrode 48 arranged at intervals.

[0154] Please refer to it again. Figure 14The WO electrode 45 includes a first conductive sheet 451, a second conductive sheet 452, and a first fixed claw 453, which are spaced apart and arranged opposite to each other. The first conductive sheet 451 is part of the first side 1 of the electrode assembly 424. The second conductive sheet 452 is part of the second side 2 of the electrode assembly 424, and one end of the second conductive sheet 452 forms part of the first triangular portion 7 of the electrode assembly 424, while the other end of the second conductive sheet 452 is close to the fourth corner portion 8 of the electrode assembly 424. The first fixed claw 453 is fixed to the second conductive sheet 452. In this embodiment, the first fixed claw 453 may have a bent structure. In other embodiments, the first fixed claw 453 may have other structures.

[0155] Additionally, the first conductive sheet 451 includes a connecting segment 4511 and an extension segment 4512. The connecting segment 4511 of the first conductive sheet 451 is bent and connected to the extension segment 4512 of the first conductive sheet 451. Exemplarily, the connecting segment 4511 and the extension segment 4512 of the first conductive sheet 451 can be arranged at right angles.

[0156] In this configuration, electrode W1 46 is located on one side of the first conductive sheet 451 of electrode W0 45. Electrode W1 46 includes a connecting section 461, an extension section 462, and a second retaining claw 463. The connecting section 461 of electrode W1 46 is part of the first side 1 of electrode assembly 424. One end of the extension section 462 of electrode W1 46 is bent and connected to the connecting section 461 of electrode W1 46. The other end of the extension section 462 of electrode W1 46 is part of the first corner 5 of electrode assembly 424. Exemplarily, the extension section 462 of electrode W1 46 is arranged at a right angle to the connecting section 461 of electrode W1 46.

[0157] Additionally, the second fixed jaw 463 is fixed to the extension 462 of the W1 electrode 46. In this embodiment, the second fixed jaw 463 may have a bent structure. In other embodiments, the second fixed jaw 463 may also have other structures.

[0158] In this configuration, electrode W2 47 is located on one side of the first conductive sheet 451 and the second conductive sheet 452. Specifically, electrode W2 47 is located on the side of the first conductive sheet 451 of electrode W0 45 away from electrode W1 46. Electrode W2 47 includes a connecting section 471, an extension section 472, and a third retaining claw 473. The connecting section 471 of electrode W2 47 is part of the first side 1 of electrode assembly 424. A portion of the extension section of electrode W2 47 is part of the third side 3 of electrode assembly 424. One end of the extension section 472 of electrode W2 47 is bent and connected to the connecting section 471 of electrode W2 47. The other end of the extension section 472 of electrode W2 47 is part of the third triangular portion 7 of electrode assembly 424.

The connecting section 481 of the W3 electrode 48 is located between the first conductive sheet 451 of the W0 electrode 45 and the connecting section 461 of the W1 electrode 46. The extension section 482 of the W3 electrode 48 is located inside the extension section 462 of the W1 electrode 46. The connecting section 481 of the W3 electrode 48 is part of the first side 1 of the electrode assembly 424. One end of the extension section 482 of the W3 electrode 48 is bent and connected to the connecting section 481 of the W3 electrode 48. The other end of the extension section 482 of the W3 electrode 48 forms part of the first corner 5 of the electrode assembly 424. The other end of the extension section 482 of the W3 electrode 48 is spaced apart from the other end of the extension section 462 of the W1 electrode 46. For example, the extension 482 of the W3 electrode 48 is arranged at a right angle to the connection section 481 of the W3 electrode 48.

[0161] Additionally, the fourth fixed jaw 483 is fixed to the extension 482 of the W3 electrode 48. In this embodiment, the fourth fixed jaw 483 may have a bent structure. In other embodiments, the fourth fixed jaw 483 may also have other structures.

The other end of the extension section 4912 of the third conductive sheet 491 forms part of the third side 3 of the electrode assembly 424. The extension section 4912 of the third conductive sheet 491 is located outside the extension section 472 of the W2 electrode 47. For example, the extension 4912 of the third conductive sheet 491 is arranged at a right angle to the connecting section 4911 of the third conductive sheet 491.

[0164] Additionally, the fourth conductive sheet 492 is part of the fourth side 4 of the electrode assembly 424.

[0167] Please see Figure 15 and combined Figure 14 As shown, Figure 15 yes Figure 14The diagram shows the structure of the electrode assembly 424 from another angle. A first electrode plate 493 is located between and spaced apart from the second conductive plate 452 and the fourth conductive plate 492.

[0168] The second electrode plate 494 is located on the side of the first electrode plate 493 away from the second conductive plate 452, that is, the second electrode plate 494 is located outside the first electrode plate 493. The second electrode plate 494 is the fourth corner portion 8 of the electrode assembly 424. The second electrode plate 494 includes a connecting section 4941 and an extension section 4942.

[0172] Please see Figure 16 and combined Figure 14 and Figure 15 As shown, Figure 16 yes Figure 3 The diagram shows a partial structural schematic of the camera module 40. The base plate 421 of the image stabilization motor 42 is fixed to the surface of the bracket 450 away from the module circuit board 41. In addition, the extension 4512 of the first conductive sheet 451 of W0 electrode 45, the second conductive sheet 452 of W0 electrode 45, the extension 462 of W1 electrode 46, the extension 472 of W2 electrode 47, the extension 482 of W3 electrode 48, the extension 4912 of the third conductive sheet 491 of the second type electrode 4242, the fourth conductive sheet 492 of the second type electrode 4242, the extension 4932 of the first electrode sheet 493 of the third type electrode 4243, the extension 4942 of the second electrode sheet 494 of the third type electrode 4243, the extension 4952 of the third electrode sheet 495 of the fourth type electrode 4244, and the extension 4962 of the fourth electrode sheet 496 of the fourth type electrode 4244 are all fixed to the upper surface 4271 of the adhesive part 4237.

[0173] Furthermore, the connection segments 4511 of the first conductive sheet 451 of the W0 electrode 45, 461 of the W1 electrode 46, 471 of the W2 electrode 47, 481 of the W3 electrode 48, 4911 of the third conductive sheet 491 of the second type electrode 4242, 4951 of the third electrode sheet 495 of the fourth type electrode 4244, and 4961 of the fourth electrode sheet 496 of the fourth type electrode 4244 are located on one side of the bridging layer 423, pass through the first through hole 4213 of the substrate 421, and are electrically connected to the module circuit board 41. At this time, the module circuit board 41 can transmit signals to the W0 electrode 45, W1 electrode 46, W2 electrode 47, W3 electrode 48, second type electrode 4242, and fourth type electrode 4244.

[0174] Please see Figure 17 and combined Figure 16 As shown, Figure 17 yes Figure 16 The diagram shows a partial cross-sectional view of the camera module 40 along the DD line. The extension 4512 of the first conductive piece 451 of the WO electrode 45 is also connected to the first conductive post 4238 of the bridging layer 423. The second conductive piece 452 of the WO electrode 45 is connected to the second conductive post 4239 of the bridging layer 423. Thus, the first conductive piece 451 of the WO electrode 45 can be electrically connected to the second conductive piece 452 of the WO electrode 45 through the first conductive post 4238, the conductive portion 4233 of the bridging layer 423, and the second conductive post 4239.

[0175] Please see Figure 18 and combined Figure 15 As shown, Figure 18 yes Figure 16 The diagram shows a partial view of the camera module 40 from another angle. The connection segment 4931 of the first electrode piece 493 of the third type electrode 4243 and the connection segment 4941 of the second electrode piece 494 of the third type electrode 4243 are located on the other side of the bridging layer 423, passing through the second through-hole 4214 of the substrate 421 and electrically connected to the module circuit board 41. At this time, the module circuit board 41 can also transmit signals to the third type electrode 4243.

[0176] Please see Figure 19 , Figure 19 yes Figure 9 The diagram shows an enlarged view of the spring 425. The spring 425 is ring-shaped. The spring 425 includes a main body 4251, a first spring arm 4252, and a second spring arm 4253. Both the first spring arm 4252 and the second spring arm 4253 can be L-shaped. The spring 425 is made of a conductive material.

[0177] The main body 4251 includes a first side portion 4254 and a second side portion 4255 disposed opposite to each other, and a third side portion 4256 and a fourth side portion 4257 disposed opposite to each other. The third side portion 4256 and the fourth side portion 4257 are connected between the first side portion 4254 and the second side portion 4255.

[0178] In addition, the main body 4251 is provided with a first movable claw 4281, a second movable claw 4282, a third movable claw 4283, and a fourth movable claw 4284 spaced apart. The first movable claw 4281 and the second movable claw 4282 are located at the connection between the second side 4255 and the third side 4256. The third movable claw 4283 and the fourth movable claw 4284 are located at the connection between the first side 4254 and the fourth side 4257. The shapes of the first movable claw 4281, the second movable claw 4282, the third movable claw 4283, and the fourth movable claw 4284 are not limited to... Figure 19 The block shape shown can be flexibly configured as needed.

[0179] The first spring arm 4252 includes a first fixed end 4285 and a second fixed end 4286. The first fixed end 4285 is fixedly connected to the first side portion 4254 of the main body portion 4251. The second fixed end 4286 is located on the same side as the third side portion 4256. The first spring arm 4252 is inclined relative to the main body portion 4251.

[0180] Additionally, the second spring arm 4253 includes a third fixed end 4287 and a fourth fixed end 4288. The third fixed end 4287 is fixed to the second side portion 4255 of the main body portion 4251. The fourth fixed end 4288 is located on the same side as the fourth side portion 4257. The second spring arm 4253 is inclined relative to the main body portion 4251.

[0181] Please see Figure 20 and combined Figure 16 and Figure 19 As shown, Figure 20 yes Figure 3 The diagram shows a partial structural schematic of the camera module 40. A spring 425 is disposed on the side of the electrode assembly 424 away from the bridging layer 423. The second fixed end 4286 of the first spring arm 4252 of the spring 425 is fixed to the extension 4912 of the third conductive sheet 491 of the second type electrode 4242. The second spring arm 4253 of the spring 425 is fixed to the fourth conductive sheet 492 of the second type electrode 4242 (see reference). Figure 16(Mainly). A height difference is formed between the first fixed end 4285 and the second fixed end 4286 of the first spring arm 4252. The height of the first fixed end 4285 of the first spring arm 4252 can be understood as the distance between the first fixed end 4285 of the first spring arm 4252 and the electrode assembly 424; the height of the second fixed end 4286 of the first spring arm 4252 can be understood as the distance between the second fixed end 4286 of the first spring arm 4252 and the electrode assembly 424.

[0182] Furthermore, a height difference is formed between the third fixed end 4287 and the fourth fixed end 4288 of the second spring arm 4253. The height of the third fixed end 4287 of the second spring arm 4253 can be understood as the distance between the third fixed end 4287 of the second spring arm 4253 and the electrode assembly 424; the height of the fourth fixed end 4288 of the second spring arm 4253 can be understood as the distance between the fourth fixed end 4288 of the second spring arm 4253 and the electrode assembly 424.

[0183] Understandably, due to the height difference between the first fixed end 4285 and the second fixed end 4286 of the first spring arm 4252, and the height difference between the third fixed end 4287 and the fourth fixed end 4288 of the second spring arm 4253, the first spring arm 4252 is elastically connected to the third conductive sheet 491 of the second type electrode 4242. The second spring arm 4253 is elastically connected to the fourth conductive sheet 492. The main body 4251 of the spring sheet 425 is spaced apart from the electrode assembly 424, meaning that the main body 4251 of the spring sheet 425 does not contact the electrode sheets of the electrode assembly 424. Furthermore, since the spring sheet 425 is made of a conductive material, the third conductive sheet 491 of the second type electrode 4242, the spring sheet 425, and the fourth conductive sheet 492 of the second type electrode 4242 can be electrically connected to each other.

[0184] In other embodiments, the arrangement of the reed 425 structure can also refer to the lower reed 4312 of the lens motor 431 (see [link]). Figure 6 The structure can be arranged in a way that allows for multiple spaced-apart first connecting feet on the main body 4251 of the reed 425. Alternatively, the structure of the bracket 450 can also be referenced to the base 4311 of the lens motor 431 (see [link]). Figure 6 The structural arrangement is as follows. For example, the bracket 450 is provided with multiple positioning posts. The connection stability of the spring 425 is improved by fixing the first connecting foot of the spring 425 to the positioning posts of the bracket 450.

[0185] In other embodiments, a matching structure may also be provided between the reed 425 and the electrode assembly 424 to improve the connection stability of the reed 425.

[0186] Please refer to it again. Figure 20 and combined Figure 14 and Figure 17 As shown, one end of the first SMA line 4264 is fixed to and electrically connected to the first fixed claw 453 of the WO electrode 45. The other end of the first SMA line 4264 is fixed to and electrically connected to the fourth movable claw 4284 of the spring 425. Thus, the module circuit board 41, the third conductive sheet 491 of the second type electrode 4242, the spring 425, the first SMA line 4264, the second conductive sheet 452 of the WO electrode 45, the second conductive post 4239, the conductive portion 4233 of the bridging layer 423, the first conductive post 4238, and the first conductive sheet 451 of the WO electrode 45 constitute a first current loop. It is understood that the connection method between the first SMA line 4264 and the first fixed claw 453 and the fourth movable claw 4284 of the spring 425 is not specifically limited in this application.

[0187] Furthermore, one end of the second SMA line 4262 is fixed to and electrically connected to the third fixed claw 473 of the W2 electrode 47. The other end of the second SMA line 4262 is fixed to and electrically connected to the second movable claw 4282 of the spring 425. Thus, the module circuit board 41, the third conductive sheet 491 of the second type electrode 4242, the spring 425, the second SMA line 4262, and the W2 electrode 47 constitute a second current loop. It is understood that this application does not impose specific limitations on the connection method between the second SMA line 4262 and the third fixed claw 473 and the second movable claw 4282 of the spring 425.

[0188] Furthermore, one end of the third SMA line 4263 is fixed to and electrically connected to the fourth fixed claw 483 of the W3 electrode 48. The other end of the third SMA line 4263 is fixed to and electrically connected to the third movable claw 4283 of the spring 425. Thus, the module circuit board 41, the third conductive sheet 491 of the second type electrode 4242, the spring 425, the third SMA line 4263, and the W3 electrode 48 constitute a third current loop. It is understood that this application does not impose specific limitations on the connection method between the third SMA line 4263 and the fourth fixed claw 483 and the third movable claw 4283 of the spring 425.

[0189] In this circuit, one end of the fourth SMA line 4261 is fixed to and electrically connected to the second fixed claw 463 of the W1 electrode 46. The other end of the fourth SMA line 4261 is fixed to and electrically connected to the first movable claw 4281 of the spring 425. Thus, the module circuit board 41, the third conductive sheet 491 of the second type electrode 4242, the spring 425, the fourth SMA line 4261, and the W1 electrode 46 constitute a fourth current loop. It is understood that the connection method between the fourth SMA line 426 and the second fixed claw 463 and the first movable claw 4281 of the spring 425 is not specifically limited in this application.

[0190] It is understandable that by transmitting pulse width modulation (PWM) signals in the first, second, third, and fourth current loops, the first SMA line 4264, second SMA line 4262, third SMA line 4263, and fourth SMA line 4261 can be scaled. In this way, the first SMA line 4264, second SMA line 4262, third SMA line 4263, and fourth SMA line 4261 can drive the reed 425 to move relative to the substrate 421.

[0191] Please refer to it again. Figure 21 and combined Figure 20 As shown, Figure 21 yes Figure 5 The diagram shows a partial structural schematic of the camera module 40. The base 4311 of the lens motor 431 is fixed to the main body 4251 of the spring 425. At this time, the lens 432 is fixed to the main body 4251 of the spring 425 via the base 4311. It can be understood that when the first SMA line 4264, the second SMA line 4262, the third SMA line 4263, and the fourth SMA line 4261 move the spring 425, the lens 432 can also move relatively. Thus, when the electronic device 100 vibrates, the first SMA line 4264, the second SMA line 4262, the third SMA line 4263, and the fourth SMA line 4261 can move the spring 425 relative to the substrate 421 to counteract or reduce the displacement of the lens 432 caused by vibration, thereby ensuring better imaging quality of the camera module 40.

[0192] Additionally, the motor bracket 4319 is fixed to the adhesive portion 4237 of the bridging layer 423. Since the motor bracket 4319 is fixed with the first magnet 4316 and the second magnet 4318, part of the structure of the lens motor 431 does not need to be fixed to the main body 4251 of the reed 425. The main body 4251 of the reed 425 is less prone to material fatigue.

[0193] In this embodiment, the structure of a stabilization motor 42 is specifically described with reference to the accompanying drawings. The stabilization motor 42 has a bridging layer 423. The first conductive post 4238, the second conductive post 4239, and the conductive part 4233 of the bridging layer 423 are used to connect the first conductive piece 451 and the second conductive piece 452 of the WO electrode 45. On the one hand, in the compact structure of the electrode assembly 424, the problem of the first conductive piece 451 and the second conductive piece 452 being difficult to connect when they are spaced apart can be solved, that is, the positional constraints of the first conductive piece 451 and the second conductive piece 452 can be released. On the other hand, the surrounding area of ​​the electrode assembly 424 does not need to be arranged with many leads to meet the electrical connection requirements. In this way, the electrode pieces on the electrode assembly 424 are arranged more regularly, and the structure of the stabilization motor 42 is relatively simple.

[0194] Furthermore, compared to the scheme of arranging leads in the peripheral area of ​​the driving electrode layer, although this scheme adds a bridging layer 423 to the thickness of the image stabilization motor 42, the thickness of the bridging layer 423 can be made significantly smaller. Therefore, compared to the overall volume of the image stabilization motor 42, the volume of the bridging layer 423 is negligible. Thus, the volume of the image stabilization motor 42 in this scheme can be significantly reduced, meaning the image stabilization motor 42 can be miniaturized.

[0195] It is understood that the bridging layer 423 in this embodiment is used to electrically connect two conductive sheets. In other embodiments, the bridging layer 423 can also be used to electrically connect more than two conductive sheets.

[0196] It is understood that the anti-shake motor 42 in this embodiment only illustrates one bridging layer 423. In other embodiments, the number of bridging layers 423 may be greater than one. Each bridging layer 423 can be used to achieve an electrical connection between two conductive sheets.

[0197] In this embodiment, when PWM signals are transmitted through the first, second, third, and fourth current loops, electromagnetic radiation is generated in these loops. Within the radiation space of these loops, independent metal components will generate electromagnetic coupling. The voltage generated by these independent metal components has nowhere to dissipate. At this time, the magnetic field generated by these independent conductive components will interfere with the third type electrode 4243 (see [reference]). Figure 14 The interference pulses on the I2C signal of the third electrode 4243, caused by the interference on the I2C signal of the third electrode 4243, will lead to abnormal I2C bus communication. Please refer to [link / reference]. Figure 12In this embodiment, the flat portion 4235 of the bridging layer 423 provides better flatness for the first sublayer 4231 of the bridging layer 423, while the flat portion 4235 is not electrically connected to external devices, forming an isolated metal part. Thus, when electromagnetic coupling occurs in the flat portion 4235 of the bridging layer 423, it will interfere with the third type electrode 4243 (see [link to documentation]). Figure 14 The I2C signal on the bridging layer 423 causes abnormal I2C bus communication. Several implementation methods will be described in detail below with reference to the accompanying drawings. Each implementation method can effectively solve the problem that electromagnetic coupling in the flat portion 4235 of the bridging layer 423 affects the normal operation of the lens assembly 43.

[0198] For the first implementation method, please refer to Figure 22 , Figure 22 yes Figure 3 This is a partial structural schematic diagram of another embodiment of the camera module 40 shown. The image stabilization motor 42 also includes a conductive element 51. The conductive element 51 is fixedly connected to the flat portion 4235 of the bridging layer 423 and the substrate 421. In this case, the flat portion 4235 of the bridging layer 423 can be grounded to the substrate 421 through the conductive element 51. Exemplarily, the flat portion 4235 of the bridging layer 423 can be fixedly connected to the substrate 421 by welding. In this case, the conductive element 51 is a solder joint. It should be noted that the number, position, size, and shape of the conductive elements 51 are not limited to... Figure 22 The quantity, position, size, and shape indicated.

[0199] Understandably, when the flat portion 4235 of the bridging layer 423 is grounded to the substrate 421 via the conductive element 51, the voltage generated by the electromagnetic coupling in the flat portion 4235 of the bridging layer 423 can flow out through the conductive element 51 and the substrate 421. In this way, the flat portion 4235 of the bridging layer 423 is less likely to interfere with the I2C signals on the first electrode plate 493 and the second electrode plate 494 of the third type electrode 4243, thereby ensuring normal I2C bus communication.

[0200] Please see Figure 23 , Figure 23 yes Figure 14 The waveform of the interference signal of the anti-shake motor 42 shown is measured on the first electrode plate 493 of the third type electrode 4243. Figure 23This illustration shows that when the flat portion 4235 of the bridging layer 423 is not connected to the conductive element 51 of the substrate 421, the first electrode plate 493 of the third type electrode 4243 exhibits a significant interference signal during the test period. The peak value of the interference signal can reach 300 millivolts (mV). The interference signal significantly interferes with the SDA signal on the first electrode plate 493 of the third type electrode 4243. It should be noted that the 300 millivolts (mV) in this embodiment was measured under specific testing conditions. In other embodiments, the peak value of the interference signal may be other values.

[0201] Please see Figure 24 , Figure 24 yes Figure 22 The waveform of the interference signal of the anti-shake motor 42 shown is measured on the first electrode plate 493 of the third type electrode 4243. Figure 24 The diagram illustrates the interference signal waveform measured on the third type electrode 4243 when the conductive element 51 is fixedly connected to the flat portion 4235 of the bridging layer 423 and the substrate 421. According to... Figure 24 It can be seen that during the test period, the interference signal waveform on the first electrode plate 493 of the third type electrode 4243 basically disappeared, indicating that the interference signal on the first electrode plate 493 of the third type electrode 4243 was basically eliminated, thus ensuring normal I2C bus communication.

[0202] Understandably, by Figure 23 and Figure 24 It can be seen that by fixing the conductive member 51 between the flat portion 4235 of the bridging layer 423 and the substrate 421, the flat portion 4235 of the bridging layer 423 is less likely to interfere with the SDA signal on the first electrode piece 493 of the third type electrode 4243, thereby ensuring normal I2C bus communication.

[0203] For example, the interference signal waveform on the third type electrode 4243 can be measured by an oscilloscope or other equipment to ensure the accuracy of the measured interference wave of the third type electrode 4243.

[0204] In other embodiments, the interference signal interference to the second electrode plate 494 of the third type electrode 4243 is substantially eliminated by measuring the interference signal waveform on the second electrode plate 494 of the third type electrode 4243.

[0205] For the second implementation method, please refer to [link / reference]. Figure 25 , Figure 25 yes Figure 3The diagram shows a partial cross-sectional view of another embodiment of the camera module 40 at the BB line. The image stabilization motor 42 also includes a conductive element 51. The conductive element 51 is fixedly connected between the flat portion 4235 of the bridging layer 423 and the housing 470. In this case, the flat portion 4235 of the bridging layer 423 can be grounded to the housing 470 through the conductive element 51. Exemplarily, the flat portion 4235 of the bridging layer 423 can be fixedly connected to the housing 470 by welding (e.g., laser welding, brazing). In this case, the conductive element 51 is a solder joint. It should be noted that the number, position, size, and shape of the conductive elements 51 are not limited to... Figure 22 The quantity, position, size, and shape indicated.

[0206] Understandably, when the flat portion 4235 of the bridging layer 423 is grounded to the housing 470 via the conductive element 51, the voltage generated by electromagnetic coupling in the flat portion 4235 of the bridging layer 423 can flow out through the conductive element 51 and the housing 470. In this way, the flat portion 4235 of the bridging layer 423 is less likely to interfere with the I2C signal on the third type electrode 4243, thereby ensuring normal I2C bus communication.

[0207] The above description, in conjunction with the accompanying drawings, details two grounding methods for the flat portion 4235 of the bridging layer 423 to address the issue of electromagnetic coupling affecting the normal operation of I2C bus communication. It is understood that in other embodiments, the grounding method of the flat portion 4235 of the bridging layer 423 is not specifically limited. For example, the flat portion 4235 of the bridging layer 423 can be electrically connected to a grounding point via an FPC, wires, or other conductive components 51. The location of the grounding point is not limited to the substrate 421 and the housing 470 mentioned in the two embodiments above. The grounding point can be any grounding location within the camera module 40, or even any grounding location within the electronic device 100.

[0208] For the third implementation method, please refer to [link / reference]. Figure 26 , Figure 26 yes Figure 4 This is a partial structural diagram of another embodiment of the anti-shake motor 42 shown. The first connecting portion 4234 and the second connecting portion 4236 of the bridging layer 423 are both made of conductive material. In this case, the flat portion 4235 of the bridging layer 423 is electrically connected to the conductive portion 4233 of the bridging layer 423 through the first connecting portion 4234 and the second connecting portion 4236. In this case, the flat portion 4235 of the bridging layer 423 is no longer an independent metal component. The first sub-layer 4231 of the bridging layer 423 is a single conductive layer. Thus, the flat portion 4235 of the bridging layer 423 is less prone to electromagnetic coupling. The flat portion 4235 of the bridging layer 423 will not interfere with the I2C signal on the third type electrode 4243, thereby ensuring that I2C bus communication can function normally.

[0209] For the fourth implementation method, please refer to [the relevant documentation]. Figure 26 The flat portion 4235 of the bridging layer 423 is made of an insulating material (e.g., plastic). In this case, electromagnetic coupling will not occur in the flat portion 4235 of the bridging layer 423. Thus, the flat portion 4235 of the bridging layer 423 will not interfere with the I2C signal on the third type electrode 4243, thereby ensuring that I2C bus communication can function normally.

[0210] The above describes several implementation methods, each of which can solve the problem that electromagnetic coupling in the flat portion 4235 of the bridging layer 423 affects the normal operation of I2C bus communication. In other implementation methods, the above problem can also be solved in other ways. For example, please refer to... Figure 27 , Figure 27 yes Figure 3 This is a partial structural schematic diagram of another embodiment of the camera module 40 shown. By increasing the thickness D of the adhesive portion 4237 of the second sub-layer 4232 of the bridging layer 423, the distance between the first electrode piece 493 and the second electrode piece 494 of the third type electrode 4243 and the flat portion 4235 is increased. This reduces or prevents the flat portion 4235 of the bridging layer 423 from interfering with the I2C signals on the first electrode piece 493 and the second electrode piece 494, thereby ensuring that the I2C bus communication can work normally.

[0211] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
