Technical Field

[0002] The present application relates to the field of camera technology, and in particular to a camera module and an electronic device. Background Art

[0003] As smartphone cameras become increasingly powerful, major manufacturers are placing more stringent demands on the imaging quality of camera modules. Traditional camera modules consist of a housing, a voice coil motor, and a module circuit board. The voice coil motor is mounted on the module circuit board and serves to support the lens. The housing is soldered to the module circuit board and covers the voice coil motor. However, to ensure that the housing can be tinned during the soldering process, the surface of the housing needs to be electroplated with nickel. Due to the high cost of partial nickel plating on the housing, the entire surface of the housing is nickel-plated. This weakly magnetic nickel layer attracts the magnet inside the voice coil motor, generating magnetic interference.

[0004] Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide a camera module and an electronic device, wherein the housing of the camera module is not likely to generate magnetic interference to the magnetic parts of the voice coil motor, so that the camera module can obtain a better shooting experience.

[0006] In a first aspect, the present application provides a camera module. The camera module includes a voice coil motor, a lens, a module circuit board, and an image sensor;

[0007] The voice coil motor includes a base, a drive mechanism, and a housing. The lens is mounted on the drive mechanism, which is connected to the base. The base and the image sensor are both located on a module circuit board. The image sensor is located on the light-emitting side of the lens. The housing is fixed to the base and covers at least a portion of the drive mechanism.

[0008] The base includes a plastic part and a metal part, and the metal part is fixed to the plastic part; the shell includes a metal part, and the metal part is fixedly connected to the metal part, and the metal part is electrically connected to the ground pin of the module circuit board.

[0009] It is understandable that by fixing the metal part on the plastic part, the metal part can improve the strength of the plastic part. In this case, the overall strength of the base formed by the plastic part and the metal part is higher.

[0010] In one embodiment, the housing can be directly fixedly connected to the module circuit board by soldering. In the soldering process, nickel plating is required on the surface of the housing to ensure that the housing can be tinned during the soldering process, thereby ensuring the reliability of the connection between the housing and the module circuit board. Since the cost of nickel plating in a local area of ​​the housing is relatively high, the entire housing is generally directly nickel-plated to reduce costs. However, after the housing is nickel-plated, the nickel will produce magnetic interference to the magnetic parts of the voice coil motor, thereby affecting the operation of the voice coil motor. In this embodiment, a metal part is fixed on the plastic part, and the metal part is used to fix it to the metal part of the housing. At this time, the housing does not need to be nickel-plated as a whole. The housing will no longer produce magnetic interference to the magnetic parts of the voice coil motor, and the cost investment will no longer be increased due to nickel plating.

[0011] In one embodiment, the housing can be directly fixed to the module circuit board by soldering. Understandably, the small area of ​​the module circuit board's pin terminals makes assembly of the housing and the module circuit board more difficult. In this embodiment, a metal component is fixed to the plastic component and then fixedly connected to the metal portion of the housing. The size of the metal component can be set to be sufficiently large as required to ensure that the housing can be easily fixed to the metal component, thus resolving the problem of the housing being difficult to securely connect due to the small area of ​​the module circuit board's pin terminals.

[0012] It is understood that by electrically connecting the metal piece to the ground pin of the module circuit board, and then fixing the metal portion of the housing to the metal piece, the metal portion of the housing can be connected to the ground pin of the module circuit board through the metal piece, and the metal portion of the housing is grounded. In this way, when the camera module is used in an electronic device, the grounding of the housing can prevent other components of the electronic device from generating radio frequency interference and electrostatic interference on the camera module.

[0013] It can be understood that the metal parts of the base of this embodiment have the function of "one thing for multiple uses". On the one hand, the metal parts can improve the overall strength of the base to avoid damage to the base. On the other hand, the metal parts can be used to fix the metal part of the shell, thereby replacing the solution of directly fixing the shell to the module circuit board by soldering. In this case, the shell does not need to be nickel-plated as a whole. The shell will no longer generate magnetic interference to the magnetic parts of the voice coil motor, nor will the cost investment be increased due to nickel plating. On the other hand, the metal parts can serve as a transitional structural part for the metal part of the shell to be connected to the ground pin of the module circuit board.

[0014] In some possible implementations, the metal portion is fixedly connected to the metal component by laser welding.

[0015] It is understandable that, in one embodiment, the housing can be directly fixedly connected to the module circuit board by soldering. In the soldering process, nickel plating is required on the surface of the housing to ensure that the housing can be tinned during the soldering process, thereby ensuring the reliability of the connection between the housing and the module circuit board. Since the cost of nickel plating in a local area of ​​the housing is relatively high, the entire housing is generally directly nickel-plated to reduce costs. However, after the housing is nickel-plated, the nickel will produce magnetic interference to the magnetic parts of the voice coil motor, thereby affecting the operation of the voice coil motor. In this embodiment, a metal part is fixed on the plastic part, and the metal part is used to fix it to the metal part of the housing. At this time, the housing does not need to be nickel-plated as a whole. The housing will no longer produce magnetic interference to the magnetic parts of the voice coil motor, nor will the cost investment be increased due to nickel plating.

[0016] In some possible implementations, the housing includes a top plate and a side frame, wherein the side frame is connected to the periphery of the top plate; a surface of the side frame away from the top plate is provided with a protrusion, and the protrusion constitutes at least a part of the metal part.

[0017] In some possible embodiments, the metal part includes a fixing area and a first connection area, the first connection area is connected to the periphery of the fixing area; the fixing area is fixed to the plastic part, the first connection area extends relative to the side of the plastic part, and the first connection area is fixedly connected to the protrusion by laser welding.

[0018] It is understandable that by arranging the first connection area to protrude relative to the side of the plastic component, the fixed connection between the first connection area and the bump can be facilitated, that is, the difficulty of assembling the first connection area and the bump is reduced.

[0019] In some possible embodiments, the metal part also includes a second connection area, which is connected to the periphery of the fixed area and is spaced apart from the first connection area, and the second connection area is exposed relative to the side of the plastic part; the second connection area is fixedly connected to the ground pin of the module circuit board by soldering.

[0020] It is understandable that by exposing the second connection area relative to the side of the plastic component, the second connection area can be easily fixedly connected to the ground pin of the module circuit board, which reduces the difficulty of assembling the second connection area and the ground pin of the module circuit board.

[0021] In some possible implementations, the second connection region is bent away from the module circuit board and fixed to the side surface of the plastic component. This allows a larger area of ​​the second connection region to be exposed relative to the side surface of the plastic component, further facilitating a secure connection between the second connection region of the metal component and the ground pin of the module circuit board, resulting in a more stable and secure connection.

[0022] In some possible implementations, the voice coil motor further includes a buffer component, which is made of insulating material; the buffer component is connected to the inner surface of the housing, and the buffer component is arranged opposite to the driving mechanism.

[0023] It is understood that in one embodiment, black paint is applied to the inner surface of the housing to prevent the voice coil motor's wiring from short-circuiting due to contact with the housing. In addition, a buffer is attached to the voice coil motor's drive mechanism to prevent the drive mechanism from being damaged by impacting the housing during movement. It is understood that the scheme of applying black paint and attaching a buffer will greatly increase the investment cost of the camera module. In this embodiment, a buffer is fixed to the inner surface of the housing, and the material of the buffer is an insulating material. In this way, the buffer on the housing can not only prevent the voice coil motor's wiring from short-circuiting due to contact with the housing, but also prevent the drive mechanism from being damaged by impacting the housing during movement. The housing has the function of "one thing for multiple uses". In addition, this embodiment can also roughly save the cost of applying black paint, thereby greatly reducing the cost of the camera module.

[0024] In some possible implementations, the buffer component is formed into an integrated structure with the housing through an injection molding process, so that the connection between the buffer component and the housing is more stable and reliable.

[0025] In some possible embodiments, the camera module includes electronic components, which are fixed to the module circuit board and electrically connected to the module circuit board; at least a portion of the metal part is exposed relative to the bottom surface of the plastic part and is fixed on the module circuit board, and a portion of the metal part surrounds the electronic components.

[0026] It is understandable that by setting a portion of the metal parts of the base around the electronic components, when the camera module swings or collides, the position where the module circuit board is fixedly connected to the electronic components can be prevented from being deformed, thereby avoiding the risk of cracking the solder joints between the module circuit board and the base, thereby improving the reliability of the camera module. Therefore, the metal parts of the base of this embodiment not only have the multiple functions mentioned above, but also have the function of improving the reliability of the camera module. In addition, the electronic components and the metal parts of the base have an overlapping area in the optical axis direction of the camera module, so that the height of the camera module can be reduced.

[0027] In some possible embodiments, the electronic components include a driver chip, which is electrically connected to the voice coil motor through a module circuit board. The driver chip is used to calculate the anti-shake data of the voice coil motor, and / or, calculate the focus data, and / or control the current conditions.

[0028] In some possible embodiments, the plastic member is provided with a receiving groove, the opening of which is located on the bottom surface of the plastic member, and the electronic component is at least partially located within the receiving groove. It is understood that, along the optical axis of the camera module, the electronic component and the plastic member of the base have an overlapping area, thereby further reducing the height of the camera module.

[0029] In some possible implementations, the driving mechanism includes an anti-shake bracket, a first anti-shake coil, a first anti-shake magnetic component, a second anti-shake coil, and a second anti-shake magnetic component;

[0030] The first anti-shake magnetic component and the second anti-shake magnetic component are fixed to the anti-shake bracket at intervals;

[0031] The anti-shake bracket is movably connected to the plastic component. The first anti-shake coil and the second anti-shake coil are fixed to the plastic component at intervals. The first anti-shake coil is arranged facing the first anti-shake magnetic component and is used to drive the anti-shake bracket to move relative to the base in a first direction. The second anti-shake coil is arranged facing the second anti-shake magnetic component and is used to drive the anti-shake bracket to move relative to the base in a second direction, and the second direction intersects the first direction.

[0032] The driving mechanism also includes a focusing bracket, a focusing magnetic part and a focusing coil. The focusing bracket is located on the inner side of the anti-shake bracket, the focusing magnetic part is fixed to the focusing bracket, and the focusing coil is fixed to the anti-shake bracket and arranged facing the focusing magnetic part. It is used to drive the focusing bracket to move relative to the anti-shake bracket along a third direction, and the third direction intersects with the second direction and the first direction.

[0033] It can be understood that when the anti-shake bracket moves relative to the base along the first direction Y, the movement direction of the anti-shake bracket is perpendicular to the magnetic gap between the first anti-shake magnetic component and the first anti-shake coil. The above-mentioned magnetic gap is not affected by the movement of the anti-shake bracket. Therefore, the problem of a rapid decrease in driving force due to an increase in the magnetic gap can be avoided, thereby ensuring that the anti-shake driving force of the voice coil motor is large and the driving force is relatively stable, which is conducive to the long-stroke design of the voice coil motor's optical image stabilization function.

[0034] It can be understood that when the anti-shake bracket moves relative to the base in the second direction X, the movement direction of the anti-shake bracket is perpendicular to the magnetic gap between the second anti-shake magnetic component and the second anti-shake coil. The above-mentioned magnetic gap is not affected by the movement of the anti-shake bracket. Therefore, the problem of a rapid decrease in driving force due to an increase in the magnetic gap can be avoided, thereby ensuring that the anti-shake driving force of the voice coil motor is large and relatively stable, which is conducive to the long-stroke design of the voice coil motor's optical image stabilization function.

[0035] It is understandable that in some embodiments, the anti-shake bracket is located on the inner side of the focus bracket. In this case, when the camera module needs to focus, the focus bracket needs to drive the anti-shake bracket and the lens to move along the third direction. As a result, the weight of the mover formed by the focus bracket, the anti-shake bracket, and the lens is relatively heavy, which requires the focus drive assembly to increase the driving force by increasing the volume. Therefore, this arrangement is not conducive to the lightweight and miniaturized design of the voice coil motor. In this embodiment, by arranging the focus bracket on the inner side of the anti-shake bracket. In this case, when the camera module needs to focus, the focus bracket needs to drive the lens to move along the third direction Z. In this way, the mover in the focusing process of this embodiment can omit the anti-shake bracket, that is, the weight of the mover formed by the focus bracket and the lens is relatively light, which is conducive to the miniaturization of the focus drive assembly. The voice coil motor of this embodiment can achieve a lightweight and miniaturized design.

[0036] It is understandable that, compared to the solution where the anti-shake bracket is located inside the focus bracket, the anti-shake bracket requires at least two anti-shake drive assemblies to drive the anti-shake bracket in the XY plane. As a result, the voice coil motor requires at least two sets of wiring to provide signals and power to the anti-shake drive assemblies. Moreover, at least two sets of wiring must pass through the focus bracket. Therefore, the power supply configuration of this solution is relatively complex, increasing the difficulty of setting up the voice coil motor. However, in this embodiment, by placing the focus bracket inside the anti-shake bracket, since the focus bracket requires a set of focus drive assemblies to drive the focus bracket in the third direction Z, the voice coil motor also requires a set of wiring to provide signals and power to the focus drive assembly, that is, a set of wiring must pass through the anti-shake bracket. Therefore, the power supply scheme of the solution of this embodiment is relatively simple, which can greatly reduce the difficulty of setting up the voice coil motor.

[0037] In some possible implementations, the plane in which the wire of the focus coil is wound (i.e., the winding plane) may be parallel to the third direction Z. In this case, the focus coil is arranged vertically, so that the focus coil occupies a smaller area in the XY plane, which is beneficial to the miniaturization of the voice coil motor. The focus magnetic part may include two opposite polarity directions, both of which are perpendicular to the third direction Z. In this case, the focus magnetic part can be arranged vertically, thereby reducing the space occupied by the focus magnetic part in the XY plane, facilitating the miniaturization design of the voice coil motor.

[0038] It is understood that both the focus drive assembly and the anti-shake drive assembly of the voice coil motor utilize a moving magnet design. The voice coil motor's drive in the first direction Y, second direction X, and third direction Z is independently controlled by a set of drive components (including coils and magnetic components). Specifically, when the focus bracket of the voice coil motor moves relative to the anti-shake bracket in the third direction Z for autofocus, the relative position of the anti-shake bracket and the base is not affected, and the magnetic gap width of the anti-shake drive assembly is not likely to change. Similarly, when the anti-shake bracket moves relative to the base in the first direction Y and / or second direction X for optical image stabilization, the focus bracket moves with the anti-shake bracket, and the relative position of the two is not affected, and the magnetic gap width of the focus drive assembly is not likely to change. Therefore, the focus drive assembly and the anti-shake drive assembly of the voice coil motor are decoupled, and they do not interfere with each other during movement, which helps ensure the driving accuracy of the voice coil motor.

[0039] In some possible implementations, the first anti-shake coil, first anti-shake magnetic component, second anti-shake coil, and second anti-shake magnetic component of the voice coil motor can all be arranged roughly in the XY plane. By increasing the width of the magnetic components (i.e., the dimension of the first anti-shake magnetic component in the first direction Y and the dimension of the second anti-shake magnetic component in the second direction X), the motion range of the anti-shake bracket in the first direction Y and / or the second direction X can be increased, which facilitates achieving a long-stroke design for optical image stabilization without increasing the height of the voice coil motor. Furthermore, since the motion resistance of the voice coil motor during optical image stabilization is primarily due to the sliding friction between the support component and the mating structural component and is unrelated to the motion range, the resistance does not increase significantly during long-stroke optical image stabilization, thereby enabling a long-stroke design for optical image stabilization without significantly increasing the driving force.

[0040] In some possible implementations, the driving mechanism further includes a guide bracket, and the guide bracket is L-shaped;

[0041] The guide bracket includes a first supporting portion, a first connecting portion, a second supporting portion, a second connecting portion and a third supporting portion connected in sequence. The first supporting portion, the second supporting portion and the third supporting portion are connected to the plastic portion through multiple first supporting members, and are connected to the anti-shake bracket through multiple second supporting members, so that the relative movement direction of the anti-shake bracket and the guide bracket is different from the relative movement direction of the guide bracket and the base; the first connecting portion and the second connecting portion are made of metal material.

[0042] It is understood that, compared to a solution in which plastic is integrally injection-molded onto a metal frame, with a portion of the metal frame and the plastic forming the first and second connecting portions, the first and second connecting portions of this embodiment comprise only the metal frame, i.e., no longer include the injection-molded plastic. This eliminates the problem of the plastic shrinking due to cooling and pulling on the metal frame, thus preventing the guide bracket from losing dimensional accuracy due to deformation.

[0043] As can be understood, the L-shaped guide bracket is significantly smaller than a frame-shaped structure, saving space on both sides, thereby facilitating the miniaturization of the voice coil motor and camera module. Furthermore, since the three support sections of the guide bracket (i.e., the first, second, and third support sections) correspond to the three corners of the anti-shake bracket, the first anti-shake magnetic element and the first anti-shake coil are located between the first and second support sections, and the second anti-shake magnetic element and the second anti-shake coil are located between the second and third support sections, the guide bracket can ensure the reliable connection between the anti-shake bracket and the base while reducing its size. This provides stable support and accurate guidance, ensuring the stability of the relative positions of the first anti-shake magnetic element and the first anti-shake coil, and the second anti-shake magnetic element and the second anti-shake coil, thereby ensuring smooth and reliable optical image stabilization of the voice coil motor.

[0044] In some possible embodiments, the guide bracket includes a metal frame, a first plastic block, a second plastic block, and a third plastic block; the metal frame is L-shaped, and includes a first long segment and a second long segment, wherein the second end of the first long segment is connected to the first end of the second long segment; the first plastic block wraps the first end of the first long segment, the second plastic block wraps the second end of the first long segment and the first end of the second long segment, and the third plastic block wraps the second end of the second long segment;

[0045] The first end of the first long strip segment of the metal skeleton and the first plastic block constitute the first support part of the guide bracket, the second end of the first long strip segment of the metal skeleton, the first end of the second long strip segment and the second plastic block constitute the second support part of the guide bracket, the second end of the second long strip segment of the metal skeleton and the third plastic block constitute the third support part of the guide bracket, the middle part of the first long strip segment of the metal skeleton constitutes the first connecting part of the guide bracket, and the middle part of the second long strip segment of the metal skeleton constitutes the second connecting part of the guide bracket.

[0046] It can be understood that the structure of the guide bracket in this embodiment is relatively simple.

[0047] In some possible implementations, the anti-shake bracket includes an insulating body and a metal insert, wherein the metal insert is embedded in the insulating body; and the metal insert is grounded.

[0048] It is understood that, on the one hand, by embedding the metal insert in the insulating body, the metal insert can improve the strength of the insulating body, thereby enhancing the overall strength of the anti-shake bracket formed by the insulating body and the metal insert. On the other hand, by grounding the metal insert, it is less likely to interfere with the RF signal of the camera module.

[0049] In some possible implementations, the driving mechanism includes a focus circuit board and a focus drive chip, the focus coil and the focus drive chip are fixed to the focus circuit board, and the focus circuit board is fixed to the anti-shake bracket;

[0050] The anti-shake bracket includes a first conductive member, which is embedded in the insulating body and electrically connected to the negative power supply of the focus drive chip through the focus circuit board; the metal insert is electrically connected to the first conductive member.

[0051] It is understood that the metal insert can be directly grounded through the first conductive member of the anti-shake bracket. This metal insert grounding method can reuse the first conductive member of the anti-shake bracket, meaning that no additional components are required. The metal insert grounding method of this embodiment is relatively simple, with a high component utilization rate, meaning that the first conductive member of the anti-shake bracket has a "single object, multiple uses" function.

[0052] In some possible embodiments, the metal insert has a protruding block on its surface, and the first conductive member has a recessed area. The protruding block is located within the recessed area and contacts the wall of the recessed area. It is understood that the electrical connection between the metal insert and the first conductive member in this embodiment is relatively simple.

[0053] In some possible implementations, the protruding block is riveted into the recessed area. This makes the connection between the metal insert and the first conductive member more reliable and more secure. In this case, the electrical connection between the metal insert and the first conductive member is more reliable.

[0054] In some possible implementations, the anti-shake bracket further includes a second conductive member, the second conductive member being embedded in the insulating body and electrically connected to a positive power supply terminal of the focus driver chip via a focus circuit board; the anti-shake bracket is provided with a first connecting hole, the first connecting hole connecting the interior and exterior of the anti-shake bracket, and the first end of the first conductive member and the first end of the second conductive member extending into the first connecting hole;

[0055] A first isolation groove is provided on the hole wall of the first communicating hole. The first isolation groove is located between the first end portion of the first conductive member and the first end portion of the second conductive member.

[0056] It is understandable that by providing a first isolation groove between the first end of the first conductive member and the first end of the second conductive member, the first isolation groove can be used to prevent the first end of the first conductive member and the first end of the second conductive member from being too close to each other when the anti-shake bracket undergoes high-temperature carbonization, thereby preventing a micro short circuit from occurring. Therefore, in this embodiment, the distance between the first end of the first conductive member and the first end of the second conductive member can be set relatively close. In this way, the size of the first connecting hole can be set relatively small. The first connecting hole occupies less space in the anti-shake bracket, which means that the anti-shake bracket can free up more space to arrange other components of the voice coil motor.

[0057] In some possible embodiments, the anti-shake bracket further includes a third conductive member and a fourth conductive member, both of which are embedded in the insulating body, and the third conductive member is electrically connected to the SDA terminal of the I2C signal of the focus driver chip via the focus circuit board. The fourth conductive member is electrically connected to the SCL terminal of the I2C signal of the focus driver chip via the focus circuit board; the anti-shake bracket is provided with a second connecting hole, the second connecting hole connecting the interior and exterior of the anti-shake bracket and spaced apart from the first connecting hole, and the first end of the third conductive member and the first end of the fourth conductive member extend into the second connecting hole;

[0058] A second isolation groove is provided on the hole wall of the second communicating hole. The second isolation groove is located between the first end of the third conductive component and the first end of the fourth conductive component.

[0059] It is understandable that by providing a second isolation groove between the first end of the third conductive member and the first end of the fourth conductive member, the second isolation groove can be used to prevent the first end of the third conductive member and the first end of the fourth conductive member from being close to each other when the anti-shake bracket undergoes high-temperature carbonization, thereby preventing a micro-short circuit from occurring due to the close distance between them. Therefore, the distance between the first end of the third conductive member and the first end of the fourth conductive member in this embodiment can be set relatively close. In this way, the size of the second connecting hole can be set relatively small. The second connecting hole occupies less space in the anti-shake bracket, which means that the anti-shake bracket can free up more space to arrange other components of the voice coil motor.

[0060] In some possible implementations, the metal insert is made of a magnetic conductive material, and the first anti-shake magnetic component and the second anti-shake magnetic component are both disposed opposite to the metal insert.

[0061] It is understood that the metal insert can be used to increase the magnetic field strength of the first and second anti-shake magnetic components. Furthermore, the metal insert can generate an attractive force between the first and second anti-shake magnetic components, thereby preventing the first and second anti-shake magnetic components from separating from the anti-shake bracket.

[0062] In some possible implementations, the anti-shake bracket is connected to the focus bracket via a plurality of third support members;

[0063] The third support member includes a shaft body and a protrusion. The protrusion is protruding from the first end surface of the shaft body. Part of the peripheral side surface of the shaft body is fixedly connected to the anti-shake bracket. The protrusion is inserted into the fixing hole of the anti-shake bracket.

[0064] It can be understood that by inserting the protrusion of the third support member into the fixing hole of the anti-shake bracket, the connection between the third support member and the anti-shake bracket is made more stable, that is, the third support member is prevented from tilting relative to the anti-shake bracket to a large extent.

[0065] In some possible implementations, the module circuit board is provided with a first avoidance space, and an opening of the first avoidance space is located on a surface of the module circuit board facing the base;

[0066] The anti-shake bracket includes a fixing portion, and the fixing hole is located on the fixing portion;

[0067] The metal part includes a sinking portion, which is arranged opposite to the fixing portion. The sinking portion sinks toward the first avoidance space and is located in the first avoidance space. The sinking portion surrounds a second avoidance space, and at least part of the fixing portion is located in the second avoidance space.

[0068] It can be understood that in this embodiment, a first avoidance space is first provided in the module circuit board so that the sinking portion can sink into the first avoidance space and be located in the first avoidance space, and the sinking portion can enclose a second avoidance space. At this time, the fixed portion of the anti-shake bracket fixedly connected to one end of the third support member is set in the second avoidance space, so that space can be freed up between the module circuit board and the third support member. The freed up space can be used to increase the length of the third support member. In this way, this embodiment can improve the overall strength of the base through metal parts, and while not occupying the space between the module circuit board and the third support member, it can also greatly increase the length of the third support member, thereby greatly improving the stability of the focusing bracket through the longer third support member, that is, the focusing bracket is not prone to overturning.

[0069] In some possible implementations, the camera module includes a first sub-reed and a second sub-reed, and the first sub-reed and the second sub-reed are both connected to the anti-shake bracket and the focus bracket;

[0070] The first sub-reed and the second sub-reed are located on the same side of the focusing bracket and are arranged adjacent to each other;

[0071] A portion of the first sub-reed is recessed in a direction away from the second sub-reed to form a first recessed area. A portion of the second sub-reed is recessed in a direction away from the first sub-reed to form a second recessed area. The first recessed area and the second recessed area enclose a first glue dispensing space. A first glue material is disposed in the first glue dispensing space.

[0072] It will be appreciated that the first adhesive material connecting the first and second sub-springs prevents them from shaking, thereby improving the stability of the connection between them. Furthermore, compared to a case where the first and second sub-springs are parallel and enclose a glue dispensing space, the glue dispensing space in this embodiment is larger. This prevents glue from overflowing onto the side of the first sub-spring away from the second sub-spring during the dispensing process. Furthermore, during the focusing process of the focusing bracket, the first adhesive material is less likely to become debonded due to collision with the focusing bracket, resulting in a more stable and reliable connection between the first and second sub-springs in this embodiment. Furthermore, during the dispensing process, glue is less likely to overflow onto the side of the second sub-spring away from the first sub-spring. Furthermore, during the anti-shake operation of the anti-shake bracket, the first adhesive material is less likely to become debonded due to collision with the anti-shake bracket, resulting in a more stable and reliable connection between the first and second sub-springs in this embodiment.

[0073] In some possible implementations, the voice coil motor further includes a limit bracket, the limit bracket including a top plate and side frames, the side frames being connected to a periphery of the top plate, the top plate being fixed to a top surface of the anti-shake bracket, and the side frames being fixed to a side surface of the anti-shake bracket, the anti-shake bracket and the top plate of the limit bracket cooperating to limit a movement range of the focus bracket in the third direction;

[0074] The side frame includes a first side portion and a second side portion, the second side portion is connected to the first side portion, and the first side portion and the second side portion are respectively fixed to the side surfaces of two adjacent side portions of the anti-shake bracket;

[0075] The top plate is provided with a positioning hole, the first side portion is provided with a first mounting hole, and the second side portion is provided with a second mounting hole;

[0076] A first mounting block and a second mounting block are respectively protruded from the side surfaces of two adjacent sides of the anti-shake bracket, and a positioning block is protruded from the top surface of the anti-shake bracket. The first mounting block is located in the first mounting hole, and the second mounting block is located in the second mounting hole. The positioning blocks are inserted into the positioning holes.

[0077] In the second direction, the size of the first mounting hole is larger than the size of the first mounting block and the size of the second mounting block. In the third direction, the size of the first mounting hole is larger than the size of the first mounting block and the size of the positioning block.

[0078] In the third direction, the size of the second mounting hole is larger than the size of the second mounting block and the size of the positioning block.

[0079] It is understood that in one embodiment, the first mounting block of the anti-shake bracket is tightly fitted with the first mounting hole of the limit bracket, and the second mounting block of the anti-shake bracket is tightly fitted with the second mounting hole of the limit bracket, thereby ensuring a stable connection between the limit bracket and the anti-shake bracket. In this embodiment, during assembly of the limit bracket and the anti-shake bracket, to ensure that the first mounting block of the anti-shake bracket fits tightly with the first mounting hole of the limit bracket, and the second mounting block of the anti-shake bracket fits tightly with the second mounting hole of the limit bracket, the limit bracket needs to be assembled onto the anti-shake bracket from the top along the third direction Z. In this case, during assembly, the first side edge of the limit bracket is likely to come into contact with the first mounting block of the anti-shake bracket, and the second side edge of the limit bracket is likely to come into contact with the second mounting block of the anti-shake bracket. This not only increases the difficulty of assembling the limit bracket and the anti-shake bracket, but also easily causes the limit bracket to deform due to squeezing, which poses a risk of irreversible deformation. Even if the limit bracket is assembled onto the anti-shake bracket, it is difficult to position the limit bracket, which is not conducive to subsequent welding operations. In this embodiment, the first mounting hole is configured such that, in the second direction, the size of the first mounting block is larger than the size of the first mounting block and the size of the second mounting block. In the third direction, the size of the first mounting hole is larger than the size of the first mounting block and the size of the positioning block. Furthermore, in the third direction, the size of the second mounting hole is larger than the size of the second mounting block and the size of the positioning block. Consequently, during assembly of the position-limiting bracket and the anti-shake bracket, the position-limiting bracket can first be moved relative to the anti-shake bracket in the second direction X to fit the first mounting block into the first mounting hole. The position-limiting bracket can then be moved relative to the anti-shake bracket in the first direction Y to fit the second mounting block into the second mounting hole. The position-limiting bracket can then be moved relative to the anti-shake bracket in the third direction Z to insert the positioning block into the positioning hole. Finally, glue can be filled into the first and second mounting holes, so that the first mounting block is glued to the wall of the first mounting hole, and the second mounting block is glued to the wall of the second mounting hole. This ensures a stable connection between the position-limiting bracket and the anti-shake bracket. It can be understood that this embodiment of the position-limiting bracket and the anti-shake bracket can prevent deformation of the position-limiting bracket due to squeezing during assembly.

[0080] In some possible embodiments, the camera module further includes a variable aperture located on the side of the lens. The variable aperture has an aperture whose size can be automatically adjusted. Light can enter the lens through the aperture of the variable aperture. The variable aperture is used to adjust the amount of light entering, allowing the camera module to maintain consistent image quality under various brightness conditions.

[0081] In a second aspect, an embodiment of the present application further provides an electronic device, comprising a device housing and any one of the above-mentioned camera modules, wherein the camera module is disposed in the device housing. The electronic device provides a better shooting experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0126] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0127] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the two are connected to each other and the relative position relationship after connection remains unchanged. "Sliding connection" means that the two are connected to each other and can slide relative to each other after connection. The directional terms mentioned in the embodiments of the present application, such as "top", "bottom", "up", "down", "inside", "outside", etc., are only referenced to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. "Multiple" means at least two. A and / or B include three schemes, specifically Scheme A, Scheme B and Scheme AB. Among them, "electrical connection" means that electrical signals can be conducted between each other. In addition, the two components are integrated into an integrated structure through an integrated molding process, which means that in the process of forming one of the two components, the component is connected to the other component, and there is no need to connect the two components together through further processing (such as bonding, welding, snap connection, screw connection).

[0128] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of the features.

[0129] In addition, in the embodiments of the present application, the mathematical concepts mentioned, such as parallel and perpendicular, are all in terms of the current state of the art, rather than being absolutely strict definitions in a mathematical sense. A small amount of deviation is allowed, and being approximately parallel or approximately perpendicular is acceptable. For example, A and B are parallel, which means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. For example, A and B are perpendicular, which means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0130] It is understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.

[0131] FIG1 is a schematic structural diagram of an electronic device 1000 provided in an embodiment of the present application.

[0132] As shown in FIG1 , in some embodiments, electronic device 1000 may be a device with a camera function, such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, an in-vehicle device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses, or a VR helmet. The electronic device 1000 in the embodiment shown in FIG1 is described using a mobile phone as an example.

[0133] FIG2 is a partial cross-sectional schematic diagram of the electronic device 1000 shown in FIG1 taken along line AA in some embodiments.

[0134] As shown in Figures 1 and 2, in some embodiments, the electronic device 1000 may include a camera module 100, a device housing 200, and a screen 300. The camera module 100 may be a rear camera module or a front camera module. It should be noted that Figure 1 and the related figures below only schematically illustrate some components included in the electronic device 1000, and the actual shape, actual size, actual position and actual structure of these components are not limited by Figure 1 and the figures below. In addition, when the electronic device 1000 is a device of some other form, the electronic device 1000 may also not include the screen 300.

[0135] The device housing 200 may include a frame 201 and a back cover 202. The back cover 202 is fixed to the frame 201. For example, the back cover 202 may be fixed to the frame 201 by gluing, snapping, or the like. The back cover 202 may also be integrally formed with the frame 201, i.e., the back cover 202 and the frame 201 form a single, integral structure.

[0136] In some embodiments, the screen 300 can be located on the side of the frame 201 away from the back cover 202. In this case, the screen 300 and the back cover 202 can be located on either side of the frame 201. The screen 300, the frame 201, and the back cover 202 together enclose the interior of the electronic device 1000. The interior of the electronic device 1000 can be used to house components of the electronic device 1000, such as a battery, a receiver, or a microphone. The screen 300 can be flat or curved.

[0137] For example, the camera module 100 can be located inside the electronic device 1000. The camera module 100 can be located on the side of the screen 300 facing the back cover 202. The back cover 202 can have a light hole 203. The shape of the light hole 203 is not limited to the circular shape shown in FIG1. ​​The light hole 203 connects the interior of the electronic device 1000 to the exterior of the electronic device 1000. Light from outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light hole 203. The camera module 100 can collect light entering the interior of the electronic device 1000.

[0138] FIG3 is a schematic structural diagram of some embodiments of the camera module 100 shown in FIG1 , and FIG4 is a schematic partial decomposition diagram of some embodiments of the camera module 100 shown in FIG3 .

[0139] As shown in Figures 3 and 4, the camera module 100 includes a voice coil motor 1, a lens 2, a module circuit board 3, an image sensor 4, electronic components 5, a filter holder 6a, a filter 6b, and a variable aperture 7. The image sensor 4 is also called a photosensitive chip or a photosensitive element. The image sensor 4 is used to collect ambient light and convert the image information carried by the ambient light into an electrical signal. The electronic component 5 can be a capacitor, inductor, resistor, or chip. Figure 4 schematically illustrates the electronic component 5 with a dotted frame.

[0140] It is understood that the camera module 100 may include fewer or more structures. For example, the camera module 100 may include fewer structures. For example, the camera module 100 may not include the electronic component 5, and / or the filter holder 6a, and / or the filter 6b, and / or the variable aperture 7.

[0141] It will be understood that, for ease of description, the camera module 100 will be defined as having a first direction Y, a second direction X, and a third direction Z. The first direction Y may be the width direction of the camera module 100, the second direction X may be the length direction of the camera module 100, and the second direction X is perpendicular to the first direction Y. The third direction Z may be the height direction of the camera module 100, and the third direction Z is perpendicular to the first direction Y and the second direction X. In other embodiments, the coordinate system of the camera module 100 may be flexibly configured according to specific practical needs.

[0142] FIG5 is a partial cross-sectional schematic diagram of the camera module 100 shown in FIG3 taken along line BB in some embodiments.

[0143] As shown in Figure 5, the image sensor 4 can be mounted on the module circuit board 3 and electrically connected to the module circuit board 3. In this case, signals can be transmitted between the image sensor 4 and the module circuit board 3. Furthermore, the electronic component 5 is also mounted on the module circuit board 3 and electrically connected to the module circuit board 3. In this case, signals can be transmitted between the electronic component 5 and the module circuit board 3.

[0144] Illustratively, the filter holder 6a is fixedly connected to the module circuit board 3. The filter holder 6a and the image sensor 4 are located on the same side of the module circuit board 3. The filter holder 6a is provided with a light passage 61a. The filter 6b is fixedly connected to the filter holder 6a. The filter 6b can be located within the light passage 61a. The filter 6b is also positioned opposite the image sensor 4. The filter 6b can be used to filter infrared light, blue light, and other light from light entering the image sensor 4, thereby ensuring that the image sensor 4 has excellent imaging quality.

[0145] As shown in Figure 5, the voice coil motor 1 is fixed to the module circuit board 3. The voice coil motor 1 and the image sensor 4 are located on the same side of the module circuit board 3. The lens 2 is mounted on the voice coil motor 1. The image sensor 4 is located on the light-emitting side of the lens 2. It can be understood that in the third direction Z, the image sensor 4, the optical filter 6b, and the lens 2 are arranged in sequence. In this case, the image sensor 4 is located on the light-emitting side of the lens 2. The optical filter 6b is located between the lens 2 and the image sensor 4.

[0146] It is understood that the lens 2 can be used to collect ambient light. The optical axis direction of the lens 2 can be parallel to the third direction Z of the camera module 100. The optical axis direction of the lens 2 is the same as the optical axis direction of the camera module 100.

[0147] It can be understood that compared with the solution of fixing the voice coil on the filter holder, this embodiment avoids the stacking of the voice coil motor 1 and the filter holder 6a in the third direction Z by fixing the voice coil motor 1 on the module circuit board 3, that is, the voice coil motor 1 and the filter holder 6a can be staggered in the XY plane, thereby greatly reducing the height of the camera module 100.

[0148] It is understandable that the voice coil motor 1 can be a focus voice coil motor. In this way, the voice coil motor 1 can achieve auto focus (AF) by controlling the movement of the lens 2 along the third direction Z. The voice coil motor 1 can also be an anti-shake voice coil motor. In this way, the voice coil motor 1 can control the movement of the lens 2 along a plane perpendicular to the third direction Z (i.e., the XY plane). When the camera module 100 collects ambient light, if the electronic device 1000 vibrates in the XY plane due to external force, the movement of the lens 2 in the XY plane can be controlled by the voice coil motor 1 to offset the shaking stroke of the lens 2 in the XY plane, thereby avoiding or reducing the position offset of the lens 2 caused by the shaking. In other words, the camera module 100 of the present application can control the movement of the lens 2 in the XY plane through the voice coil motor 1 to achieve optical image stabilization (OIS) of the camera module 100 and improve the imaging quality of the camera module 100. The voice coil motor 1 can also be a voice coil motor 1 with integrated anti-shake and focus. In this way, the voice coil motor 1 can achieve both autofocus and optical image stabilization by controlling the lens 2. This embodiment is described by taking an example where the voice coil motor 1 is an integrated anti-shake and focus voice coil motor 1.

[0149] It is understood that the voice coil motor 1 can be a motor driven by the force generated by the combination of a coil and a magnetic component. Specifically, the driving force of the voice coil motor 1 can be the force used to drive the lens 2 for focus and / or the force used to drive the lens 2 for anti-shake. When the voice coil motor 1 integrates focus and anti-shake, the force driving the lens 2 for focus and the force driving the lens 2 for anti-shake can be different, but at least one of the force driving the lens 2 for focus or the force driving the lens 2 for anti-shake can be the force generated by the combination of the coil and the magnetic component. For example, the force driving the lens 2 for focus is the force generated by the combination of the coil and the magnetic component, while the force driving the lens 2 for anti-shake can be the force generated by the combination of the coil and the magnetic component, or it can be the force generated by other structural components (such as the expansion and contraction force of a shape memory alloy (SMA)).

[0150] 3 and 4 , the variable aperture 7 may be located on the light-incoming side of the lens 2. In the third direction Z, the image sensor 4, the filter 6b, the lens 2, and the variable aperture 7 are arranged in sequence.

[0151] It is understood that the variable aperture 7 has an aperture 7a whose size can be automatically adjusted. Light can enter the lens 2 through the aperture 7a of the variable aperture 7. The variable aperture 7 is used to adjust the amount of light entering, so that the camera module 100 can maintain consistent shooting quality under various brightness conditions.

[0152] The above text generally introduces the structure of the camera module 100 in conjunction with the relevant drawings. The following text will specifically introduce the structure of the voice coil motor 1 in conjunction with the relevant drawings.

[0153] FIG. 6 is a partially exploded schematic diagram of the voice coil motor 1 shown in FIG. 4 in some embodiments.

[0154] As shown in Figure 6 , the voice coil motor 1 includes a base 10, a drive mechanism 20, and a housing 30. The drive mechanism 20 is used to mount the lens 2. The drive mechanism 20 is connected to the base 10. By controlling the movement of the lens 2 relative to the base 10, the drive mechanism 20 achieves both focusing and optical image stabilization. It will be appreciated that the structure of the drive mechanism 20 will be described in detail below in conjunction with the accompanying drawings. This description will not be repeated here. Furthermore, Figure 6 schematically illustrates the drive mechanism 20 with a dashed box.

[0155] FIG. 7 is a partially exploded schematic diagram of the base 10 shown in FIG. 6 in some embodiments.

[0156] As shown in Figure 7, the base 10 includes a plastic part 11 and a metal part 12. For example, the metal part 12 can be made of stainless steel or the like.

[0157] As shown in FIG7 , the plastic part 11 includes a side surface 111 and a top surface 112 and a bottom surface 113 disposed opposite each other. The side surface 111 connects the top surface 112 and the bottom surface 113. The plastic part 11 is provided with a first through hole 114. The first through hole 114 forms an opening in the top surface 112 and the bottom surface 113 of the plastic part 11. In this case, the plastic part 11 can be generally annular.

[0158] As shown in Figure 7, the metal component 12 includes a fixed area 121, a first connection area 122, and a second connection area 123. The first connection area 122 and the second connection area 123 are spaced apart and connected to the periphery of the fixed area 121. It is understood that the number of first connection areas 122 is not limited to the eight shown in Figure 7. This application does not specify the specific number. Furthermore, the number of second connection areas 123 is not limited to the one shown in Figure 7. This application does not specify the specific number either.

[0159] For example, the first connection region 122 may protrude relative to a side surface of the fixing region 121. In this case, the first connection region 122 may be disposed parallel to the fixing region 121.

[0160] For example, the second connection area 123 may protrude relative to the top surface of the fixing area 121. In other words, the second connection area (123) is bent relative to the fixing area 121 along the third direction Z. In this case, the second connection area 123 may be arranged perpendicular to the fixing area 121.

[0161] FIG8 is a schematic structural diagram of the base 10 shown in FIG6 at another angle.

[0162] As shown in FIG8 , the metal member 12 is fixed to the plastic member 11. The metal member 12 can be disposed around the first through hole 114 of the plastic member 11. The metal member 12 can be used to improve the overall strength of the base 10.

[0163] In one embodiment, the fixing region 121 of the metal component 12 can be fixed to the bottom surface 113 of the plastic component 11. In this case, the fixing region 121, the first connection region 122, and the second connection region 123 of the metal component 12 can all be exposed relative to the plastic component 11. Furthermore, the first connection region 122 of the metal component 12 can extend relative to the side surface 111 of the plastic component 11. The second connection region 123 of the metal component 12 can be exposed relative to the side surface 111 of the plastic component 11 and fixed to the side surface 111 of the plastic component 11.

[0164] In one embodiment, a portion of the metal member 12 is embedded within the plastic member 11. For example, a portion of the fixing region 121 of the metal member 12 is embedded within the plastic member 11. Both the first connection region 122 and the second connection region 123 of the metal member 12 may be exposed relative to the plastic member 11. Furthermore, the first connection region 122 of the metal member 12 may extend relative to the side surface 111 of the plastic member 11. The second connection region 123 of the metal member 12 may be exposed relative to the side surface 111 of the plastic member 11 and fixed thereto.

[0165] As shown in Figure 5, the drive mechanism 20 is connected to the base 10. The lens 2 is mounted on the drive mechanism 20. Thus, the drive mechanism 20 can drive the lens 2 to move relative to the base 10. Furthermore, the base 10 is disposed on the module circuit board 3. The base 10 and the image sensor 4 can be located on the same side of the module circuit board 3. It is understood that the lens 2 is disposed opposite the optical filter 6b through the first through hole 114 of the base 10. Thus, light collected by the lens 2 can be projected onto the optical filter 6b through the first through hole 114 of the base 10, and the light can then pass through the optical filter 6b and be projected onto the image sensor 4.

[0166] For example, the metal member 12 of the base 10 can be fixed to the module circuit board 3 by adhesive. The metal member 12 of the base 10 is staggered with the image sensor 4 and the electronic components 5. In other words, the metal member 12 of the base 10 is arranged away from the image sensor 4 and the electronic components 5 (see Figure 4).

[0167] For example, a portion of the filter holder 6a can pass through the first through-hole 114 of the plastic component 11 and enter the interior of the voice coil motor 1. In this case, a portion of the filter holder 6a is located within the voice coil motor 1. This allows the filter holder 6a and the voice coil motor 1 to overlap in the third direction Z, significantly reducing the height of the camera module 100.

[0168] As shown in Figure 6, the housing 30 includes a top plate 31 and side frames 32, with the side frames 32 connected to the periphery of the top plate 31. For example, both the side frames 32 and the top plate 31 can be made of metal. In this case, the side frames 32 and the top plate 31 constitute the metal portion 36 of the housing 30. In other embodiments, a portion of the top plate 31 and / or the side frames 32 is made of metal and a portion is made of insulating material. The portion made of metal constitutes the metal portion 36 of the housing 30.

[0169] In this embodiment, the side frame 32 and the top plate 31 are integrally formed structural members. In other embodiments, the side frame 32 can also be connected to the periphery of the top plate 31 by other processes (such as welding, bonding, or fastening, etc.).

[0170] As shown in FIG6 , in one embodiment, a bump 35 is provided on the surface of the side frame 32 away from the top plate 31. The bump 35 is made of metal. The bump 35 constitutes at least a portion of the metal portion 36. It will be understood that when both the side frame 32 and the top plate 31 are made of metal, the bump 35, the side frame 32, and the top plate 31 together constitute the metal portion 36. When both the side frame 32 and the top plate 31 are made of insulating materials, the bump 35 constitutes the entire metal portion 36.

[0171] It is understandable that the protrusion 35, the side frame 32 and the top plate 31 can be an integrally formed structural member. In other embodiments, the protrusion 35 can also be protruded on the surface of the side frame 32 away from the top plate 31 by other processes (such as welding, bonding or fastening, etc.).

[0172] As shown in Figures 5 and 6, the top plate 31 is provided with a second through hole 33. The second through hole 33 can pass through the top surface and the bottom surface of the top plate 31. In this case, the top plate 31 can be substantially annular.

[0173] Furthermore, the side frame 32 of the housing 30 is fixed to the base 10 and covers at least a portion of the voice coil motor 1. A portion of the lens 2 can extend outside the housing 30 through the second through hole 33 of the top plate 31 of the housing 30. The housing 30 can be used to protect the voice coil motor 1.

[0174] FIG9 is a schematic structural diagram of the camera module 100 shown in FIG3 in some embodiments.

[0175] As shown in Figures 8 and 9 , the bump 35 is exemplarily fixedly connected to the first connection area 122 of the metal member 12 of the base 10 by laser welding. At this point, the housing 30 is fixedly connected to the module circuit board 3 via the metal member 12 of the base 10. Figure 9 schematically distinguishes the bump 35 from the side frame 32 using dotted lines.

[0176] In one embodiment, the side frame 32 can be directly fixedly connected to the module circuit board 3 by soldering. It is understood that during the soldering process, the side frame 32 surface must be nickel-plated to ensure that the side frame 32 can be tinned during the soldering process, thereby ensuring a reliable connection between the side frame 32 and the module circuit board 3. Because nickel plating in a localized area of ​​the side frame 32 is costly, the entire housing 30 is typically nickel-plated to reduce costs. However, nickel plating on the side frame 32 can cause magnetic interference with the magnetic components of the voice coil motor 1, thereby affecting the operation of the voice coil motor 1. In this embodiment, the side frame 32 is fixedly connected to the first connection area 122 of the metal component 12 of the base 10 by laser welding. This eliminates the need for nickel plating on the housing 30, preventing magnetic interference with the voice coil motor 1 and reducing the cost of nickel plating.

[0177] In other embodiments, the protrusion 35 may also be fixed to the first connection region 122 of the metal member 12 of the base 10 in other fixing manners.

[0178] In other embodiments, when the surface of the side frame 32 away from the top plate 31 does not have the protrusion 35 , the side frame 32 can be directly fixedly connected to the first connection area 122 of the metal member 12 of the base 10 by laser welding.

[0179] Exemplarily, the second connection area 123 of the metal part 12 of the base 10 is fixedly connected to the ground pin 3a of the module circuit board 3. Exemplarily, the second connection area 123 of the metal part 12 can be fixedly connected to the ground pin 3a of the module circuit board 3 by soldering. It can be understood that the side frame 32 of the housing 30 is connected to the ground pin 3a of the module circuit board 3 through the metal part 12. At this time, the top plate 31 and the side frame 32 of the housing 30 are grounded as a whole. In this way, when the camera module 100 is applied to the electronic device 1000, by grounding the housing 30, other components of the electronic device 1000 can be prevented from generating radio frequency interference and electrostatic interference to the camera module 100. In addition, during the soldering process, the connectivity between the metal part 12 and the module circuit board 3 can be improved by nickel plating on the metal part 12. Since the plastic part 11 is located between the nickel of the metal part 12 and the voice coil motor 1 , the nickel of the metal part 12 is farther away from the voice coil motor 1 . In addition, the area of ​​the nickel of the metal part 12 is smaller, so the magnetic interference of the nickel of the metal part 12 on the voice coil motor 1 is smaller.

[0180] In other embodiments, the second connection area 123 of the metal member 12 of the base 10 may also be fixedly connected to the ground pin 3a of the module circuit board 3 by conductive adhesive.

[0181] It can be understood that the second connection area 123 of the metal part 12 of this embodiment is bent in a direction away from the module circuit board 3, so that the area of ​​the second connection area 123 exposed relative to the side 111 of the plastic part 11 is larger, which is more conducive to the fixed connection between the second connection area 123 of the metal part 12 and the ground pin 3a of the module circuit board 3, that is, the connection is more stable and firmer.

[0182] It can be understood that the metal part 12 of the base 10 of this embodiment has the function of "one thing for multiple uses". On the one hand, the metal part 12 of the base 10 can improve the overall strength of the base 10 to prevent damage to the base 10. On the other hand, the metal part 12 can be used to fix the metal part 36 of the shell 30, thereby replacing the solution of directly fixing the shell 30 to the module circuit board 3 by soldering. In this case, the shell 30 does not need to be nickel-plated as a whole. The shell 30 will no longer generate magnetic interference with the magnetic parts of the voice coil motor 1, and the cost investment will no longer be increased due to nickel plating. On the other hand, the metal part 12 of the base 10 can serve as a transitional structural part for the shell 30 to be connected to the ground pin 3a of the module circuit board 3.

[0183] Fig. 10 is a schematic structural diagram of the housing 30 shown in Fig. 6 at another angle. Fig. 11 is a schematic structural diagram of the housing 30 shown in Fig. 6 at yet another angle.

[0184] As shown in Figures 10 and 11, the housing 30 further includes a buffer member 34. For example, the buffer member 34 is made of an insulating material, such as plastic. In other embodiments, a metal sheet, such as a steel sheet, may also be embedded in the buffer member 34.

[0185] The buffer member 34 is fixed to the inner surface of the housing 30. The buffer member 34 is disposed opposite the drive mechanism 20. For example, the buffer member 34 can be integrally formed with the housing 30 through an injection molding process. In other embodiments, the buffer member 34 can also be fixed to the inner surface of the housing 30 through bonding or other fixing methods. The details are not further described here.

[0186] As shown in Figures 10 and 11 , the buffer 34 exemplarily includes a first sub-buffer 341, a second sub-buffer 342, a third sub-buffer 343, and a fourth sub-buffer 344. The first sub-buffer 341, the second sub-buffer 342, the third sub-buffer 343, and the fourth sub-buffer 344 can be provided separately, all connected as a single unit, or at least two connected as a single unit. This application does not limit this in detail.

[0187] The first sub-buffer 341, the second sub-buffer 342, the third sub-buffer 343, and the fourth sub-buffer 344 are respectively connected to the first side wall 321, the second side wall 322, the third side wall 323, and the fourth side wall 324 of the side frame 32. The first side wall 321 and the third side wall 323 are disposed opposite each other. The second side wall 322 and the fourth side wall 324 are disposed opposite each other. The third side wall 323 and the fourth side wall 324 are connected between the first side wall 321 and the second side wall 322. In other embodiments, the buffer 34 may also include a fifth sub-buffer (not shown). The fifth sub-buffer is connected to the inner surface of the top plate 31.

[0188] In one embodiment, the inner surface of the housing 30 is coated with black paint to prevent short circuits in the voice coil motor 1's wiring due to contact with the housing 30. Furthermore, a buffer is attached to the drive mechanism 20 of the voice coil motor 1 to prevent damage to the drive mechanism 20 from impacting the housing 30 during movement. It is understandable that coating the housing 30 with black paint and attaching a buffer significantly increase the investment cost of the camera module 100. In this embodiment, a buffer 34 made of an insulating material is fixed to the inner surface of the housing 30. This buffer 34 on the housing 30 not only prevents short circuits in the voice coil motor 1's wiring due to contact with the housing 30, but also prevents damage to the drive mechanism 20 from impacting the housing 30 during movement. The housing 30 thus serves multiple purposes. Furthermore, this embodiment substantially eliminates the cost of coating the housing with black paint, significantly reducing the cost of the camera module 100.

[0189] Fig. 12 is a schematic diagram of a portion of the structure of the camera module 100 shown in Fig. 3 in some embodiments. Fig. 13 is a schematic diagram of a portion of the cross-section of the camera module 100 shown in Fig. 3 taken along CC in some embodiments.

[0190] As shown in Figures 12 and 13, in one embodiment, a portion of the metal part 12 of the base 10 is arranged around the electronic component 5. In this way, when the camera module 100 swings or collides, the position of the module circuit board 3 that is fixedly connected to the electronic component 5 can be prevented from being deformed, thereby avoiding the risk of cracking the solder joint between the module circuit board 3 and the base 10, thereby improving the reliability of the camera module 100. Therefore, the metal part 12 of the base 10 of this embodiment not only has the multiple functions mentioned above, but also has the function of improving the reliability of the camera module 100. In addition, the electronic component 5 and the metal part 12 of the base 10 have an overlapping area in the Z-axis direction, so that the height of the camera module 100 in the Z-axis direction can be reduced.

[0191] In one embodiment, the electronic component 5 includes a driver chip 5a. The driver chip 5a is electrically connected to the voice coil motor 1 through the module circuit board 3. The driver chip 5a can be used to calculate the anti-shake data of the voice coil motor 1, and / or the focus data, and / or the current control. For example, the driver chip 5a can calculate the anti-shake offset of the voice coil motor 1, and / or the focus movement distance, and / or whether current is flowing or the current size when it is energized. In this way, when the camera module 100 swings or collides, the position of the module circuit board 3 that is fixed to the driver chip 5a can be prevented from deformation, thereby avoiding the risk of cracking the solder joint between the module circuit board 3 and the base 10, thereby improving the reliability of the camera module 100. Therefore, the metal part 12 of this embodiment not only has the multiple functions mentioned above, but also has the function of improving the reliability of the camera module 100.

[0192] As shown in FIG13 , in one embodiment, a receiving groove 115 is provided on the plastic member 11 of the base 10, with the opening of the receiving groove 115 located at the bottom surface 113 of the plastic member 11. At least a portion of the electronic component 5 is located within the receiving groove 115. It will be appreciated that, in the Z-axis direction, the electronic component 5 and the plastic member 11 of the base 10 have an overlapping area, thereby further reducing the height of the camera module 100.

[0193] An embodiment of the voice coil motor 1 is described in detail below with reference to the relevant drawings.

[0194] FIG14 is a schematic structural diagram of the base 10 shown in FIG6 in one embodiment.

[0195] As shown in FIG14 , in some embodiments, the plastic member 11 of the base 10 may include a first side portion 11a, a second side portion 11b, a third side portion 11c, and a fourth side portion 11d. The first side portion 11a and the third side portion 11c are disposed opposite each other. The second side portion 11b and the fourth side portion 11d are disposed opposite each other. The second side portion 11b and the fourth side portion 11d are connected between the first side portion 11a and the third side portion 11c.

[0196] In some embodiments, the plastic member 11 of the base 10 may be provided with a plurality of first grooves 116. For example, there may be three first grooves 116, each located at the junction of the first side 11a and the fourth side 11d, the junction of the first side 11a and the second side 11b, and the junction of the second side 11b and the third side 11c. The first grooves 116 may be recessed from the top surface of the plastic member 11 toward the interior of the plastic member 11, with the first grooves 116 extending parallel to the first direction Y. The plastic member 11 may include a plurality of first stopper groups, each corresponding to the plurality of first grooves 116. Each first stopper group includes two first stoppers 117 protruding from the top surface of the plastic member 11, with the two first stoppers 117 located at either end of the corresponding first groove 116. For example, the arrangement of the two first stoppers 117 may be parallel to the extension direction of the first grooves 116.

[0197] In some embodiments, the base 10 further includes a plurality of conductive members 118. The plurality of conductive members 118 may be embedded in the plastic member 11. The plurality of conductive members 118 may form a plurality of transmission channels for signal transmission or current transmission. For example, the conductive members 118 may be arranged in the first side 11a and the second side 11b of the plastic member 11. For example, portions of the ends of the conductive members 118 may be exposed from the outer periphery of the plastic member 11, and portions of the ends of the conductive members 118 may be exposed from the upper surface of the plastic member 11.

[0198] It can be understood that in the drawings of this embodiment, for simplicity of illustration, when the drawings include the same structure, some structures may be labeled and some structures may not be labeled, or all structures may be labeled.

[0199] FIG. 15 is a partially exploded schematic diagram of the driving mechanism 20 shown in FIG. 6 in some embodiments.

[0200] As shown in FIG15 , in some embodiments, the drive mechanism 20 includes an anti-shake drive module 21 and a focus drive module 22. The anti-shake drive module 21 drives the lens 2 for optical image stabilization, while the focus drive module 22 drives the lens 2 for autofocus. The anti-shake drive module 21 and the focus drive module 22 form an integrated drive mechanism 20. Thus, compared to a drive mechanism 20 in which the anti-shake drive module 21 and the focus drive module 22 are separately provided, the voice coil motor 1 of this embodiment is smaller in size, facilitating a miniaturized design of the voice coil motor 1 and thereby saving internal space in electronic devices.

[0201] It is understandable that the drive mechanism 20 may further include more structures. For example, the drive mechanism 20 includes a position limiting bracket 23. The structure of the position limiting bracket 23 will be described in detail below with reference to the relevant drawings. No further details will be given here.

[0202] For example, the anti-shake driving module 21 may include an anti-shake driving assembly 211, a guide bracket 212, an anti-shake bracket 213, a first support member 214, and a second support member 215. There may be multiple first support members 214 and second support members 215, for example, three are used in this embodiment.

[0203] Illustratively, the anti-shake drive assembly 211 includes a first anti-shake coil 2111, a first anti-shake magnetic component 2112, a second anti-shake coil 2113, and a second anti-shake magnetic component 2114. The first anti-shake coil 2111 and the first anti-shake magnetic component 2112 are arranged in correspondence to form one drive assembly, and the second anti-shake coil 2113 and the second anti-shake magnetic component 2114 are arranged in correspondence to form another drive assembly.

[0204] It is understandable that the anti-shake driving module 21 may further include more structures. For example, the anti-shake driving module 21 may further include a first anti-shake sensor 216 and a second anti-shake sensor 217 .

[0205] For example, the focus driving module 22 may include a focus bracket 221, a focus driving assembly 222, a circuit board assembly 223, and a third support member 224. The number of the third support members 224 may be two.

[0206] For example, the focus drive assembly 222 may include a focus coil 2221, a focus magnetic component 2222, and a focus magnetic conductive component 2223. The circuit board assembly 223 includes a focus circuit board 2231, a focus drive chip 2232, a focus sensor 2233, and a focus magnetic component 2234. In other embodiments, the circuit board assembly 223 may not include the focus sensor 2233 and / or the focus magnetic component 2234.

[0207] FIG16 is a first schematic diagram of a partial structure of the voice coil motor 1 shown in FIG6 in one embodiment.

[0208] As shown in FIG16 , in some embodiments, a plurality of first support members 214 can be mounted in a one-to-one correspondence within the plurality of first grooves 116 . Part of the outer surface of the first support member 214 protrudes relative to the top surface of the plastic member 11 . The first support member 214 is positioned between two corresponding first stoppers 117 . The two first stoppers 117 are used to position the first support member 214, thereby stabilizing the relative position between the first support member 214 and the base 10 and preventing the first support member 214 from falling out. In some embodiments, the first support member 214 can also be fixedly connected to the base 10 by methods such as gluing or welding.

[0209] Exemplarily, the first support member 214 can adopt a sliding shaft structure, such as a cylindrical structure. When the first support member 214 is installed in the first groove 116, the axial direction of the sliding shaft is parallel to the extension direction of the first groove 116. Alternatively, the first support member 214 can also adopt a ball structure. In this case, the first support member 214 can include a plurality of balls. When the first support member 214 is installed in the first groove 116, the arrangement direction of the plurality of balls is parallel to the extension direction of the first groove 116. Among them, the plurality of first support members 214 can all adopt a sliding shaft structure, or all adopt a ball structure, or adopt a combination structure of a sliding shaft and a ball. This embodiment of the present application does not strictly limit this. At this time, the plurality of first support members 214 can include at least one of a sliding shaft or a ball.

[0210] In some other embodiments, the plurality of first support members 214 may also form an integrated structural member together with the base 10 , which will not be described in detail here.

[0211] In some embodiments, the first anti-shake coil 2111 is mounted on the first side 11 a of the plastic component 11 to be fixed to the base 10 . The second anti-shake coil 2113 is mounted on the second side 11 b of the plastic component 11 to be fixed to the base 10 .

[0212] In some embodiments, the first anti-shake sensor 216 is fixed to the first edge 11a of the plastic component 11 and is located inside the first anti-shake coil 2111. The first anti-shake sensor 216 is used to implement position detection and can be a Hall sensor or a tunnel magneto-resistance (TMR) sensor.

[0213] In some embodiments, the second anti-shake sensor 217 is fixed to the second edge 11b of the plastic component 11 and is located inside the second anti-shake coil 2113. The second anti-shake sensor 217 is used to detect position and can be a Hall sensor or a TMR sensor.

[0214] Fig. 17 is a schematic diagram of the structure of the guide bracket 212 shown in Fig. 15 in one embodiment. Fig. 18 is a schematic diagram of the structure of the guide bracket 212 shown in Fig. 17 from another angle.

[0215] As shown in Figures 17 and 18, in some embodiments, the guide bracket 212 can be roughly L-shaped. The guide bracket 212 can include a first support portion 2121, a first connecting portion 2122, a second support portion 2123, a second connecting portion 2124, and a third support portion 2125, which are connected in sequence. The first support portion 2121, the second support portion 2123, and the third support portion 2125 are arranged in pairs, with the first connecting portion 2122 connecting the first support portion 2121 and the second support portion 2123, and the second connecting portion 2124 connecting the second support portion 2123 and the third support portion 2125. The first connecting portion 2122 and the second connecting portion 2124 can be arranged at an angle. For example, the first connecting portion 2122 and the second connecting portion 2124 can be arranged perpendicular to each other or approximately perpendicular to each other.

[0216] As shown in Figures 17 and 18 , the guide bracket 212 can, for example, be provided with a plurality of second grooves 2126. The plurality of second grooves 2126 are disposed on the same side of the guide bracket 212. The number of second grooves 2126 can be three, one located in the first support portion 2121, the second support portion 2123, and the third support portion 2125. The second grooves 2126 can extend parallel to the second direction X. The second grooves 2126 can be recessed from a side surface of the corresponding support portion toward the interior of the support portion. The guide bracket 212 can also include a plurality of second stopper groups, each corresponding to the plurality of second grooves 2126. Each second stopper group includes two protruding second stoppers 2128, one located at each end of the corresponding second groove 2126. For example, the arrangement of the two second stoppers 2128 can be parallel to the extension direction of the second grooves 2126.

[0217] As shown in Figures 17 and 18 , the guide bracket 212 can further include a plurality of first chutes 2127, which are arranged away from the plurality of second grooves 2126. The number of first chutes 2127 can be three, with the three first chutes 2127 respectively located on the first support portion 2121, the second support portion 2123, and the third support portion 2125. The first chutes 2127 can extend parallel to the first direction Y. The first chutes 2127 can be recessed from the other side surface of the corresponding support portion toward the interior of the support portion. The first chutes 2127 can extend through the corresponding support portion, forming a through-groove.

[0218] As shown in Figures 17 and 18, by way of example, the first support portion 2121 and the second support portion 2123 can be located on one side of the first connecting portion 2122 in the first direction Y, that is, the first connecting portion 2122 is arranged to avoid the space directly opposite the first supporting portion 2121 and the second supporting portion 2123, and the first supporting portion 2121, the first connecting portion 2122, and the second supporting portion 2123 can be roughly U-shaped. The second support portion 2123 and the third support portion 2125 can be located on one side of the second connecting portion 2124 in the second direction X, that is, the second connecting portion 2124 is arranged to avoid the space directly opposite the second supporting portion 2123 and the third supporting portion 2125, and the second supporting portion 2123, the second connecting portion 2124, and the third supporting portion 2125 can be roughly U-shaped.

[0219] Exemplarily, the first connection portion 2122 and the second connection portion 2124 are made of metal.

[0220] It will be appreciated that, compared to a solution in which plastic is integrally injection-molded onto a metal frame, and a portion of the metal frame and the plastic thereon form the first connecting portion 2122 and the second connecting portion 2124, the first connecting portion 2122 and the second connecting portion 2124 of this embodiment comprise only the metal frame, i.e., no longer comprise injection-molded plastic. This eliminates the problem of the plastic shrinking due to cooling and pulling on the metal frame, thus preventing deformation of the guide bracket 212 resulting in a loss of dimensional accuracy.

[0221] It is understood that although the metal frames of the first connecting portion 2122 and the second connecting portion 2124 no longer include injection-molded plastic, the metal frames of the first supporting portion 2121, the second supporting portion 2123, and the third supporting portion 2125 may include injection-molded plastic. Because the lengths of the first supporting portion 2121, the second supporting portion 2123, and the third supporting portion 2125 are shorter than those of the first connecting portion 2122 and the second connecting portion 2124, the metal frames of the first supporting portion 2121, the second supporting portion 2123, and the third supporting portion 2125 are less likely to deform due to cooling of the plastic.

[0222] The structure of the guide bracket 212 is described in detail below with reference to the relevant drawings.

[0223] FIG19 is a schematic exploded view of the guide bracket 212 shown in FIG17 in one embodiment.

[0224] As shown in FIG19 , in some embodiments, the guide bracket 212 includes a metal frame 212a, a first plastic block 212b, a second plastic block 212c, and a third plastic block 212d. For example, the metal frame 212a can be formed by bending or stamping an integral metal member 12, i.e., the metal frame 212a is an integrated structure.

[0225] It can be understood that the metal skeleton 212a of the guide bracket 212 includes a first long segment 2121a and a second long segment 2122a.

[0226] The first end 2123a and the second end 2124a of the first elongated segment 2121a are bent relative to the middle portion of the first elongated segment 2121a in the first direction Y. In other words, the first end 2123a and the second end 2124a of the first elongated segment 2121a can be located on the same side of the middle portion of the first elongated segment 2121a in the first direction Y. In this case, the first elongated segment 2121a is generally U-shaped.

[0227] The first end 2125a and the second end 2126a of the second elongated segment 2122a are bent relative to the middle portion of the second elongated segment 2122a in the second direction X. In other words, the first end 2125a and the second end 2126a of the second elongated segment 2122a may be located on the same side of the middle portion of the second elongated segment 2122a in the second direction X. In this case, the second elongated segment 2122a is generally U-shaped.

[0228] The second end 2124a of the first elongated segment 2121a is connected to the first end 2125a of the second elongated segment 2122a. The metal frame 212a of the guide bracket 212 can be substantially L-shaped. For example, the first elongated segment 2121a and the second elongated segment 2122a can be arranged perpendicular to each other or substantially perpendicular to each other.

[0229] As shown in Figure 19, the first plastic block 212b wraps around the first end 2123a of the first elongated segment 2121a. The second plastic block 212c wraps around the second end 2124a of the first elongated segment 2121a and the first end 2125a of the second elongated segment 2122a. The third plastic block 212d wraps around the second end 2126a of the second elongated segment 2122a. In other words, the first end 2123a of the first elongated segment 2121a is embedded in the first plastic block 212b. The second end 2124a of the first elongated segment 2121a and the first end 2125a of the second elongated segment 2122a are both embedded in the second plastic block 212c. The second end 2126a of the second elongated segment 2122a is embedded in the third plastic block 212d.

[0230] For example, a hole is formed in the first end 2123a of the first elongated segment 2121a and the first plastic block 212b is embedded in the hole to provide a more secure connection between the first plastic block 212b and the first end 2123a of the first elongated segment 2121a. It is understood that the second end 2124a of the first elongated segment 2121a, the first end 2125a of the second elongated segment 2122a, and the second end 2126a of the second elongated segment 2122a can all refer to the arrangement of the first end 2123a of the first elongated segment 2121a.

[0231] It is understood that the first end 2123a of the first elongated segment 2121a of the metal frame 212a and the first plastic block 212b form the first support portion 2121 of the guide bracket 212 (see Figures 17 and 18). The second end 2124a of the first elongated segment 2121a of the metal frame 212a, the first end 2125a of the second elongated segment 2122a, and the second plastic block 212c form the second support portion 2123 of the guide bracket 212 (see Figures 17 and 18). The second end 2126a of the second elongated segment 2122a of the metal frame 212a and the third plastic block 212d form the third support portion 2125 of the guide bracket 212 (see Figures 17 and 18). The middle portion of the first elongated segment 2121a of the metal frame 212a forms the first connecting portion 2122 of the guide bracket 212 (see Figures 17 and 18). The middle portion of the second elongated segment 2122a of the metal frame 212a forms the second connecting portion 2124 of the guide bracket 212 (see FIG. 17 and FIG. 18 ).

[0232] It is understood that the three second grooves 2126 of this embodiment can be respectively provided on the first plastic block 212b, the second plastic block 212c, and the third plastic block 212d. The three second stopper groups can also be respectively provided on the first plastic block 212b, the second plastic block 212c, and the third plastic block 212d. The three first sliding grooves 2127 can also be respectively provided on the first plastic block 212b, the second plastic block 212c, and the third plastic block 212d.

[0233] FIG. 20 is a second schematic diagram of a partial structure of the voice coil motor 1 shown in FIG. 6 in one embodiment.

[0234] Referring to FIG. 20 , in conjunction with FIG. 18 , in some embodiments, a guide bracket 212 is mounted on the base 10. The first support portion 2121 corresponds to the connection between the first side 11a and the fourth side 11d of the plastic component 11, the second support portion 2123 corresponds to the connection between the first side 11a and the second side 11b, and the third support portion 2125 corresponds to the connection between the second side 11b and the third side 11c. The three first guide slots 2127 of the guide bracket 212 correspond to the three first grooves 116 of the base 10, and the first support members 214 mounted in the first grooves 116 partially engage with the first guide slots 2127. At this point, the first support portion 2121, the second support portion 2123, and the third support portion 2125 of the guide bracket 212 are connected to the base 10 via the multiple first support members 214. The guide bracket 212 is slidably connected to the base 10 via a plurality of first support members 214, and the relative sliding direction between the guide bracket 212 and the base 10 is parallel to the guiding direction of the first support members 214. Specifically, when the first support members 214 are configured as sliding shafts, the axial direction of the sliding shafts is the guiding direction of the first support members 214; when the first support members 214 are configured as ball bearings, the arrangement direction of the plurality of balls is the guiding direction of the first support members 214.

[0235] When the first support member 214 utilizes a sliding shaft structure, the guide bracket 212 and the first support member 214 maintain linear contact during relative motion, thereby reducing the risk of dents caused by excessive impact pressure and improving reliability. In some embodiments, the width of the contact area between the first support member 214 and the guide bracket 212 can be increased to further improve the reliability of the structural fit.

[0236] As shown in FIG20 , the guiding directions of the plurality of first support members 214 are illustratively parallel to the first direction Y, so that the guide bracket 212 can slide relative to the base 10 along the first direction Y. In some embodiments, the first support members 214 can also serve as position limiters for other structural members in a direction perpendicular to their guiding directions. For example, the provision of the first support members 214 allows the guide bracket 212 and the base 10 to be mutually limited in the second direction X.

[0237] For example, the first connection portion 2122 is provided corresponding to the first side 11a of the plastic component 11 and can be located on a side of the first anti-shake coil 2111 that is away from the third side 11c of the plastic component 11. The second connection portion 2124 is provided corresponding to the second side 11b of the plastic component 11 and can be located on a side of the second anti-shake coil 2113 that is away from the fourth side 11d of the plastic component 11.

[0238] In some embodiments, the cooperation between the multiple first support members 214 and the guide bracket 212 includes a tight fit and a loose fit to reduce the difficulty of assembly. For example, in conjunction with Figure 18, the multiple first chutes 2127 of the guide bracket 212 include at least one "V"-shaped groove and at least one "U"-shaped groove or "L"-shaped groove. When the "V"-shaped groove cooperates with the first support member 214, the side groove walls of the first chutes 2127 contact the first support member 214, achieving a tight fit. For example, the first chutes 2127 located at the first support portion 2121 and the second support portion 2123 are "V"-shaped grooves. When the "U"-shaped groove or "L"-shaped groove cooperates with the first support member 214, the bottom groove walls of the first chutes 2127 contact the first support member 214, achieving a loose fit. For example, the first chutes 2127 located at the third support portion 2125 are "U"-shaped grooves. In some other embodiments, the tight fit and loose fit designs between the multiple first support members 214 and the guide bracket 212 may have other implementation schemes, such as a combination of two loose fits and one tight fit, or changes in the arrangement positions of the tight fit and the loose fit, etc. The embodiments of the present application do not strictly limit this.

[0239] Referring to FIG. 20 , in conjunction with FIG. 17 , in some embodiments, a plurality of second support members 215 can be mounted in a one-to-one correspondence to a plurality of second grooves 2126 of the guide bracket 212 . In this case, the three second support members 215 are mounted on the first support portion 2121 , the second support portion 2123 , and the third support portion 2125 of the guide bracket 212 , respectively. Part of the outer surface of the second support member 215 protrudes relative to the surface of the corresponding support portion of the guide bracket 212 . The second support member 215 is positioned between two corresponding second stoppers 2128 . The two second stoppers 2128 are used to limit the second support member 215 so that the relative position between the second support member 215 and the guide bracket 212 is more stable, preventing the second support member 215 from falling out. In some embodiments, the second support member 215 can also be fixedly connected to the guide bracket 212 by methods such as dispensing glue or welding.

[0240] Exemplarily, the second support member 215 can adopt a sliding shaft structure, such as a cylindrical structure. When the second support member 215 is installed in the second groove 2126, the axial direction of the sliding shaft is parallel to the extension direction of the second groove 2126. Alternatively, the second support member 215 can also adopt a ball structure. In this case, the second support member 215 can include a plurality of balls. When the second support member 215 is installed in the second groove 2126, the arrangement direction of the plurality of balls is parallel to the extension direction of the second groove 2126. Alternatively, the plurality of second support members 215 adopt a combined structure of sliding shafts and balls. The sliding shaft structure and the ball structure can refer to the aforementioned structure and will not be described in detail here. At this time, the plurality of second support members 215 can include at least one of sliding shafts or balls.

[0241] In some other embodiments, the plurality of second support members 215 may also form an integrally formed structural member together with the guide bracket 212 , which will not be described in detail here.

[0242] Figure 21 is a partially exploded view of an embodiment of the anti-shake bracket 213 shown in Figure 15. Figure 22 is a schematic structural diagram of the anti-shake bracket 213 shown in Figure 15 from another angle.

[0243] As shown in FIG. 21 and FIG. 22 , the anti-shake bracket 213 includes an insulating body 2131 and a metal insert 2132 .

[0244] In one embodiment, the insulating body 2131 may be generally annular. For example, the insulating body 2131 may include a first side 2131a, a second side 2131b, a third side 2131c, and a fourth side 2131d. The first side 2131a and the third side 2131c of the anti-shake bracket 213 are disposed opposite each other. The second side 2131b and the fourth side 2131d of the anti-shake bracket 213 are disposed opposite each other. The second side 2131b and the fourth side 2131d of the anti-shake bracket 213 are connected between the first side 2131a and the third side 2131c of the anti-shake bracket 213.

[0245] Illustratively, the anti-shake bracket 213 has an active space 2133 located between the first side 2131a and the third side 2131c, and between the second side 2131b and the fourth side 2131d. That is, the first side 2131a, the second side 2131b, the third side 2131c, and the fourth side 2131d surround the active space 2133. The active space 2133 extends through the anti-shake bracket 213 in the third direction Z.

[0246] Illustratively, the anti-shake bracket 213 may be provided with a plurality of second sliding grooves 2134, which are arranged toward the same side of the anti-shake bracket 213. The number of second sliding grooves 2134 may be three, and the three second sliding grooves 2134 are respectively located at the connection between the first side 2131a and the fourth side 2131d of the anti-shake bracket 213, the connection between the first side 2131a and the second side 2131b of the anti-shake bracket 213, and the connection between the second side 2131b and the third side 2131c of the anti-shake bracket 213. The extension direction of the second sliding grooves 2134 may be parallel to the second direction X.

[0247] For example, the first side portion 2131a is provided with a first mounting groove 2135a, which is located between the two second sliding grooves 2134. The second side portion 2131b is provided with a second mounting groove 2135b, which is located between the two second sliding grooves 2134. The second mounting groove 2135b and the first mounting groove 2135a are arranged on the same side of the anti-shake bracket 213.

[0248] Exemplarily, the fourth side portion 2131d is provided with a third mounting groove 2135c, the opening of which faces the activity space 2133.

[0249] For example, the fourth side portion 2131d further includes a first sliding groove 2136. There may be two first sliding grooves 2136. The two first sliding grooves 2136 are located on either side of the third mounting groove 2135c. The extending direction of the first sliding grooves 2136 may be parallel to the third direction Z.

[0250] Exemplarily, the bottom wall of the first sliding shaft groove 2136 is further provided with a fixing hole 2137 , that is, the opening of the fixing hole 2137 is located at the bottom wall of the first sliding shaft groove 2136 .

[0251] As shown in Figure 21, the metal insert 2132 includes a first metal member 2132a and a second metal member 2132b. The second metal member 2132b is connected to one end of the first metal member 2132a. For example, the first metal member 2132a and the second metal member 2132b may be arranged at an angle. For example, the first metal member 2132a and the second metal member 2132b may be arranged perpendicularly or approximately perpendicularly to each other.

[0252] It is understood that the first metal member 2132a and the second metal member 2132b of the metal insert 2132 can be an integrally formed structure. For example, the first metal member 2132a and the second metal member 2132b of the metal insert 2132 can be formed by bending or stamping the integral metal member 12. This can reduce the number of processing steps for the first metal member 2132a and the second metal member 2132b of the metal insert 2132, thereby reducing processing costs. In other embodiments, the first metal member 2132a and the second metal member 2132b of the metal insert 2132 can also be connected to form a single unit by welding, bonding, snap-fitting, or the like. This application does not limit this in detail.

[0253] In this embodiment, the metal insert 2132 is embedded in the insulating body 2131 and can be formed into an integral structure with the insulating body 2131 through methods such as insert molding. In this case, the metal insert 2132 is embedded in the insulating body 2131. In this way, the metal insert 2132 can improve the overall strength of the anti-shake bracket 213.

[0254] For example, the first metal member 2132a of the metal insert 2132 can be embedded in the first side 2131a of the insulating body 2131. The second metal member 2132b of the metal insert 2132 can be embedded in the second side 2131b of the insulating body 2131. In other embodiments, at least a portion of the first metal member 2132a of the metal insert 2132 can be fixed to the bottom wall of the first mounting groove 2135a by bonding or other means. At least a portion of the second metal member 2132b of the metal insert 2132 can also be fixed to the bottom wall of the second mounting groove 2135b by bonding or other means.

[0255] As shown in FIG21 , in some embodiments, the anti-shake bracket 213 further includes a first conductive member 2138a, a second conductive member 2138b, a third conductive member 2138c, and a fourth conductive member 2138d, which are spaced apart. The first conductive member 2138a can serve as a transmission channel for the negative power supply (i.e., the ground line). The second conductive member 2138b can serve as a transmission channel for the positive power supply. The third conductive member 2138c can serve as a transmission channel for the SDA (serial data) signal of the I2C signal. The fourth conductive member 2138d can serve as a transmission channel for the SCL (serial clock) signal of the I2C signal.

[0256] The first conductive member 2138a, the second conductive member 2138b, the third conductive member 2138c, and the fourth conductive member 2138d can be formed into an integrally formed structure with the insulating body 2131 through insert molding or other methods. In this case, the first conductive member 2138a, the second conductive member 2138b, the third conductive member 2138c, and the fourth conductive member 2138d can be embedded in the insulating body 2131.

[0257] FIG. 23 is a schematic diagram of a partial structure of the anti-shake bracket 213 shown in FIG. 15 in one embodiment.

[0258] As shown in Figure 23, the metal insert 2132 of the anti-shake bracket 213 is electrically connected to the first conductive member 2138a of the anti-shake bracket 213. It can be understood that since the first conductive member 2138a of the anti-shake bracket 213 is a transmission channel for the negative pole of the power supply (i.e., the ground wire), the metal insert 2132 of the anti-shake bracket 213 can be grounded through the first conductive member 2138a of the anti-shake bracket 213, that is, the metal insert 2132 is grounded. At this time, the metal insert 2132 is not likely to interfere with the radio frequency signal of the camera module 100.

[0259] For example, the second metal member 2132b of the metal insert 2132 is electrically connected to the first conductive member 2138a of the anti-shake bracket 213. It is understood that because the second metal member 2132b and the first metal member 2132a of the metal insert 2132 are integrally formed, when the second metal member 2132b of the metal insert 2132 is electrically connected to the first conductive member 2138a of the anti-shake bracket 213, the first metal member 2132a of the metal insert 2132 is also electrically connected to the first conductive member 2138a of the anti-shake bracket 213.

[0260] In other embodiments, the first metal member 2132 a of the metal insert 2132 may also be electrically connected to the first conductive member 2138 a of the anti-shake bracket 213 .

[0261] As shown in FIG21 , in some embodiments, a protruding block 2132c is provided on the surface of the metal insert 2132 of the anti-shake bracket 213. It is understood that the number, position, and shape of the protruding blocks 2132c are not specifically limited.

[0262] As shown in Figure 21, in some embodiments, the first conductive member 2138a of the anti-shake bracket 213 has a recessed area 2138e. It is understood that the number, position and shape of the recessed areas 2138e can be adapted to the number, position and shape of the protruding blocks 2132c.

[0263] As shown in FIG23 , and in combination with FIG21 , the protruding block 2132 c is located within the recessed area 2138 e and contacts the wall of the recessed area 2138 e. For example, the protruding block 2132 c can be riveted into the recessed area 2138 e. This makes the connection between the first conductive member 2138 a of the anti-shake bracket 213 and the metal insert 2132 of the anti-shake bracket 213 more stable. In other embodiments, the metal insert 2132 of the anti-shake bracket 213 can also be electrically connected to the first conductive member 2138 a of the anti-shake bracket 213 by welding, conductive adhesive, or the like. This application does not limit this in detail.

[0264] FIG. 24 is a third schematic diagram of a partial structure of the voice coil motor 1 shown in FIG. 6 in one embodiment.

[0265] 24 and in combination with FIG22 , the first anti-shake magnetic component 2112 can be installed in the first installation slot 2135a to be fixed to the anti-shake bracket 213. The first anti-shake magnetic component 2112 can be a magnet or other magnetic component.

[0266] In addition, the second anti-shake magnetic component 2114 can be installed in the second installation groove 2135b to be fixed to the anti-shake bracket 213. The second anti-shake magnetic component 2114 can be a magnet or other magnetic components.

[0267] 21 , in one embodiment, the metal insert 2132 of the anti-shake bracket 213 is made of a magnetic conductive material, such as silicon steel sheets and alloys formed by various iron products and rare earth elements.

[0268] For example, the first metal member 2132a of the metal insert 2132 is disposed opposite the first anti-shake magnetic member 2112. It is understood that the first metal member 2132a of the metal insert 2132 can be used to increase the magnetic field strength of the first anti-shake magnetic member 2112. Furthermore, the first metal member 2132a of the metal insert 2132 can generate an attractive force with the first anti-shake magnetic member 2112, thereby preventing the first anti-shake magnetic member 2112 from separating from the anti-shake bracket 213.

[0269] For example, the second metal member 2132b of the metal insert 2132 is disposed opposite the second anti-shake magnetic member 2114. It is understood that the second metal member 2132b of the metal insert 2132 can be used to increase the magnetic field strength of the second anti-shake magnetic member 2114. Furthermore, the second metal member 2132b of the metal insert 2132 can generate an attractive force with the second anti-shake magnetic member 2114, thereby preventing the second anti-shake magnetic member 2114 from separating from the anti-shake bracket 213.

[0270] FIG25 is a schematic structural diagram of the third support member 224 shown in FIG15 at another angle.

[0271] As shown in FIG. 25 , the third support member 224 adopts a sliding shaft structure.

[0272] Illustratively, the third support member 224 includes a shaft body 2241 and a protrusion 2242. The shaft body 2241 includes a peripheral side surface 2243 and a first end surface 2244 and a second end surface 2245 disposed opposite to each other. The protrusion 2242 is protruded from the first end surface 2244 of the shaft body 2241. In one embodiment, the shaft body 2241 and the protrusion 2242 are both substantially cylindrical.

[0273] As shown in Figures 24 and 25 , there are two third support members 224. The two third support members 224 are fixed in the two first sliding shaft grooves 2136 in a one-to-one correspondence.

[0274] Illustratively, the peripheral side surface 2243 of the shaft body 2241 of the third support member 224 is fixed to the side wall of the first sliding shaft groove 2136. In one embodiment, the peripheral side surface 2243 of the shaft body 2241 of the third support member 224 can be fixed to the side wall of the first sliding shaft groove 2136 by adhesive.

[0275] For example, the protrusion 2242 of the third support member 224 is inserted into the fixing hole 2137 of the anti-shake bracket 213. For example, the protrusion 2242 of the third support member 224 can be tightly matched with the fixing hole 2137 of the anti-shake bracket 213.

[0276] It can be understood that by inserting the protrusion 2242 of the third support member 224 into the fixing hole 2137 of the anti-shake bracket 213, the connection between the third support member 224 and the anti-shake bracket 213 is made more stable, that is, the third support member 224 is prevented from tilting relative to the anti-shake bracket 213 to a large extent.

[0277] FIG26 is a schematic diagram of the assembly structure of the circuit board assembly 223 and the focusing coil 2221 shown in FIG15 .

[0278] As shown in FIG26 , in some embodiments, the focus driver chip 2232 and focus sensor 2233 of the circuit board assembly 223 are both fixed to the focus circuit board 2231 and electrically connected to the focus circuit board 2231. The focus coil 2221 is fixed to the focus circuit board 2231 and electrically connected to the focus circuit board 2231. It is understood that the input and output ends of the focus coil 2221 can form a current loop with the focus driver chip 2232 through the focus circuit board 2231. In this case, the focus driver chip 2232 can control the current flow through the focus coil 2221 (e.g., whether current is flowing or the amount of current flowing when current is flowing) through the focus circuit board 2231. For example, the focus coil 2221 can be arranged around the focus driver chip 2232 and focus sensor 2233. In this way, the focus driver chip 2232 and focus sensor 2233 can effectively utilize the space inside the focus coil 2221, thereby significantly improving the space utilization of the voice coil motor 1.

[0279] Illustratively, the focus magnet 2234 is fixed to the side of the focus circuit board 2231 facing away from the focus coil 2221. The focus magnet 2234 is made of a material capable of generating magnetic attraction with a magnet or other magnetic component, such as a ferromagnetic material. Furthermore, the focus magnet 2234 can also serve to increase the structural strength of the circuit board assembly 223 and reduce the risk of deformation of the focus circuit board 2231.

[0280] In other embodiments, the circuit board assembly 223 may also include a reinforcement member (not shown). The reinforcement member is fixed to the side of the focus circuit board 2231 facing away from the focus coil 2221 to increase the structural strength of the circuit board assembly 223 and reduce the risk of deformation of the focus circuit board 2231. It is understood that the position, size, and shape of the reinforcement member are not specifically limited in this embodiment.

[0281] FIG27 is a schematic structural diagram of a portion of the voice coil motor 1 shown in FIG26 at another angle.

[0282] As shown in Figures 25 and 26, the circuit board assembly 223 is illustratively installed in the third mounting slot 2135c of the anti-shake bracket 213 to secure it to the anti-shake bracket 213. At this point, the focus coil 2221 is secured to the anti-shake bracket 213 via the focus circuit board 2231. It will be appreciated that at least a portion of the circuit board assembly 223 is located in the third mounting slot 2135c, making the circuit board assembly 223 and the anti-shake bracket 213 compact, thereby improving space utilization.

[0283] Exemplarily, the focusing circuit board 2231 and the focusing magnetic member 2234 of the circuit board assembly 223 can be fixed in the third mounting groove 2135c by adhesive.

[0284] Figure 28 is a fourth schematic diagram of a partial structure of the voice coil motor 1 shown in Figure 6 in one embodiment. Figure 29 is a partial cross-sectional view of a portion of the voice coil motor 1 shown in Figure 28 at position DD in one embodiment. Figure 30 is a partial cross-sectional view of a portion of the voice coil motor 1 shown in Figure 28 at position EE in one embodiment.

[0285] As shown in Figures 28 to 30, in some embodiments, the anti-shake bracket 213 is movably connected to the base 10. The anti-shake bracket 213 is located on the side of the three supporting portions (i.e., the first supporting portion 2121, the second supporting portion 2123, and the third supporting portion 2125) of the guide bracket 212, facing away from the base 10. Specifically, the connection between the first side 2131a and the fourth side 2131d of the anti-shake bracket 213 corresponds to the first supporting portion 2121 of the guide bracket 212, the connection between the first side 2131a and the second side 2131b of the anti-shake bracket 213 corresponds to the second supporting portion 2123 of the guide bracket 212, and the connection between the second side 2131b and the third side 2131c of the anti-shake bracket 213 corresponds to the third supporting portion 2125 of the guide bracket 212. At this time, the three supporting portions of the guide bracket 212 (ie, the first supporting portion 2121 , the second supporting portion 2123 and the third supporting portion 2125 ) are located between the anti-shake bracket 213 and the base 10 .

[0286] The three second sliding grooves 2134 of the anti-shake bracket 213 correspond one-to-one with the three second grooves 2126 of the guide bracket 212. The second support member 215, mounted in the second groove 2126, partially fits into the second sliding groove 2134. The first support portion 2121, the second support portion 2123, and the third support portion 2125 of the guide bracket 212 are connected to the anti-shake bracket 213 via the multiple second support members 215. The anti-shake bracket 213 is slidably connected to the guide bracket 212 via the multiple second support members 215, with the relative sliding direction parallel to the guiding direction of the second support members 215. When the second support member 215 employs a sliding shaft structure, the axial direction of the sliding shaft serves as the guiding direction of the second support member 215. When the second support member 215 employs a ball bearing structure, the arrangement direction of the multiple balls serves as the guiding direction of the second support member 215.

[0287] When the second support member 215 utilizes a sliding shaft structure, the anti-shake bracket 213 and the second support member 215 maintain linear contact during relative motion, thereby reducing the risk of dents caused by excessive impact pressure and improving reliability. In some embodiments, the width of the contact area between the second support member 215 and the anti-shake bracket 213 can be increased to further enhance the reliability of the structural fit.

[0288] For example, as shown in Figures 28 to 30, the guiding directions of the plurality of second support members 215 are parallel to the second direction X, so that the anti-shake bracket 213 can slide relative to the guide bracket 212 along the second direction X. In some embodiments, the second support members 215 can also serve as position limiters for other structural members in a direction perpendicular to their guiding directions. For example, the provision of the second support members 215 allows the anti-shake bracket 213 and the guide bracket 212 to limit each other in the first direction Y. In other embodiments, other limiting structures can also be provided between the anti-shake bracket 213 and the guide bracket 212 to achieve mutual position limiting of the two in the first direction Y, and this embodiment of the present application is not strictly limited to this.

[0289] In the embodiment of the present application, the guiding directions of the multiple first support members 214 differ from the guiding directions of the multiple second support members 215, so that the relative motion direction of the anti-shake bracket 213 and the guide bracket 212 differs from the relative motion direction of the guide bracket 212 and the base 10, and the anti-shake bracket 213 can move in the XY plane relative to the base 10. The guiding directions of the multiple first support members 214 and the guiding directions of the multiple second support members 215 can be perpendicular to each other, or they can intersect but not be perpendicular to each other, and this embodiment of the present application does not impose a strict limitation on this.

[0290] In the above embodiment, the guiding directions of the multiple first support members 214 are parallel to the first direction Y, and the guiding directions of the multiple second support members 215 are parallel to the second direction X, so that the anti-shake bracket 213 can move along the second direction X relative to the guide bracket 212, and the anti-shake bracket 213 and the guide bracket 212 can move together along the first direction Y relative to the base 10.

[0291] In other embodiments, the guiding directions of the plurality of first support members 214 may also be parallel to the second direction X, and the guiding directions of the plurality of second support members 215 may also be parallel to the first direction Y, so that the anti-shake bracket 213 can move relative to the guide bracket 212 in the first direction Y, and the anti-shake bracket 213 and the guide bracket 212 can move together relative to the base 10 in the second direction X. In this case, the extension directions of the plurality of first grooves 116 of the base 10 and the directions of the plurality of first guide slots 2127 of the guide bracket 212 change in accordance with the guiding directions of the plurality of first support members 214, that is, change to be parallel to the second direction X; the extension directions of the plurality of second grooves 2126 of the guide bracket 212 and the directions of the plurality of second guide slots 2134 of the anti-shake bracket 213 change in accordance with the guiding directions of the plurality of second support members 215, that is, change to be parallel to the first direction Y.

[0292] As shown in Figures 28 and 30, in some embodiments, the first side 2131a of the anti-shake bracket 213 is set to correspond to the first connecting portion 2122 of the guide bracket 212, and is arranged corresponding to the first side 11a of the base 10. The second side 2131b of the anti-shake bracket 213 is set to correspond to the second connecting portion 2124 of the guide bracket 212, and is arranged corresponding to the second side 11b of the base 10. Therefore, the anti-shake bracket 213 and the guide bracket 212 are compactly arranged, which is conducive to the miniaturized design of the voice coil motor 1.

[0293] As shown in Figures 28 to 30, in some embodiments, the first connection portion 2122 of the guide bracket 212 is located on the side of the first anti-shake magnetic component 2112 facing away from the active space 2133, and the second connection portion 2124 is located on the side of the second anti-shake magnetic component 2114 facing away from the active space 2133. In this embodiment, the first connection portion 2122 and the second connection portion 2124 of the guide bracket 212 are arranged in an outwardly wound manner, staggered with the first anti-shake magnetic component 2112 and the second anti-shake magnetic component 2114 in the third direction Z. This helps reduce the height of the voice coil motor 1 and achieve miniaturization.

[0294] In this embodiment, the guide bracket 212 is L-shaped, which is significantly smaller in size than a frame-shaped structure and can save space on both sides, thereby facilitating the miniaturization of the voice coil motor 1 and the camera module 100 . In addition, since the three supporting parts of the guide bracket 212 (i.e., the first supporting part 2121, the second supporting part 2123 and the third supporting part 2125) are arranged corresponding to the three corners of the anti-shake bracket 213, the first anti-shake magnetic part 2112 and the first anti-shake coil 2111 are located between the first supporting part 2121 and the second supporting part 2123, and the second anti-shake magnetic part 2114 and the second anti-shake coil 2113 are located between the second supporting part 2123 and the third supporting part 2125, the guide bracket 212 can ensure the connection reliability of the anti-shake bracket 213 and the base 10 while reducing the volume, and can achieve the functions of stable support and accurate guidance, ensuring the stability of the relative positions of the first anti-shake magnetic part 2112 and the first anti-shake coil 2111 and the relative positions of the second anti-shake magnetic part 2114 and the second anti-shake coil 2113, so that the optical anti-shake movement of the voice coil motor 1 is smooth and reliable.

[0295] Furthermore, the voice coil motor 1 utilizes a dual-layer design consisting of a guide bracket 212 and an anti-shake bracket 213. Each bracket layer cooperates with the supporting components and adjacent structural components to provide guidance in one direction. This prevents crosstalk between the two guiding directions, thereby facilitating precise guidance for optical image stabilization. The guiding action of the multiple first supporting members 214 allows the guide bracket 212 and the anti-shake bracket 213 to move together relative to the base 10 in a first direction Y. The guiding action of the multiple second supporting members 215 allows the anti-shake bracket 213 to move relative to the guide bracket 212 in a second direction X. Consequently, the coordinated structure of the base 10, the first supporting members 214, the guide bracket 212, the second supporting members 215, and the anti-shake bracket 213 allows the voice coil motor 1 to achieve precise guidance during optical image stabilization, thereby resolving the issue of excessive lens 2 tilt during optical image stabilization associated with conventional voice coil motors 1.

[0296] Referring to FIG. 29 , in conjunction with FIG. 20 and FIG. 24 , in some embodiments, the first anti-shake magnetic component 2112 is fixed to the anti-shake bracket 213 , the first anti-shake coil 2111 is fixed to the base 10 , and the first anti-shake coil 2111 is disposed facing the first anti-shake magnetic component 2112 to drive the anti-shake bracket 213 to move relative to the base 10 in a first direction Y. The first anti-shake magnetic component 2112 and the first anti-shake coil 2111 are arranged in a third direction Z. The first anti-shake coil 2111 is disposed facing the first anti-shake magnetic component 2112, meaning that the winding plane of the first anti-shake coil 2111 faces the first anti-shake magnetic component 2112. For example, the winding plane of the first anti-shake coil 2111 can be disposed parallel to the XY plane.

[0297] For example, a first anti-shake sensor (not shown) may be fixed to the base 10 , and the position change of the anti-shake bracket 213 in the first direction Y may be detected by using the first anti-shake sensor.

[0298] In this embodiment, when the anti-shake bracket 213 moves relative to the base 10 along the first direction Y, the movement direction of the anti-shake bracket 213 is perpendicular to the magnetic gap between the first anti-shake magnetic component 2112 and the first anti-shake coil 2111. The above-mentioned magnetic gap is not affected by the movement of the anti-shake bracket 213. Therefore, the problem of a rapid decrease in driving force due to an increase in the magnetic gap can be avoided, thereby ensuring that the anti-shake driving force of the voice coil motor 1 is large and the driving force is relatively stable, which is conducive to the long-stroke design of the optical image stabilization function of the voice coil motor 1.

[0299] Among them, the first anti-shake magnetic component 2112 can have two opposite polarity directions (as shown by the arrows in the figure), and the polarity direction of the first anti-shake magnetic component 2112 is set perpendicular to the winding plane of the first anti-shake coil 2111. Among them, the coils in the two sections of the first anti-shake coil 2111 can be respectively set to correspond to the two polarity directions of the first anti-shake magnetic component 2112, and the currents in the coils in the two sections flow in opposite directions. The side of the first anti-shake magnetic component 2112 facing the first anti-shake coil 2111 includes a north pole (N) and a south pole (S), and the side of the first anti-shake magnetic component 2112 facing away from the first anti-shake coil 2111 correspondingly includes a south pole (S) and a north pole (N).

[0300] Exemplarily, the first anti-shake magnetic component 2112 may include one or more magnets, and the first anti-shake magnetic component 2112 may have various implementation structures. For example, the first anti-shake magnetic component 2112 may be a Halbach magnet array. In another example, the first anti-shake magnetic component 2112 may adopt a dual magnet structure, for example, consisting of two magnets, the two magnets arranged in the first direction Y and having opposite polarity directions. In another example, the first anti-shake magnetic component 2112 may include at least three magnets, wherein the polarization directions of the two adjacent magnets located on the edges are opposite and perpendicular to the arrangement direction of the three magnets, and the polarization direction of the magnet located in the middle is directed from one magnet to the other magnet. In another example, the first anti-shake magnetic component 2112 may also adopt a single magnet structure, for example, consisting of a single magnet including two parts with opposite polarity directions, and the magnet may be manufactured using a bipolar magnetization process.

[0301] In some embodiments, a first anti-shake magnetic component (not shown) is fixed to the base 10. The first anti-shake magnetic component is arranged facing the first anti-shake magnetic component 2112. The magnetic force between the first anti-shake magnetic component and the first anti-shake magnetic component 2112 causes the anti-shake bracket 213 to move closer to the base 10.

[0302] Referring to FIG. 30 , in conjunction with FIG. 20 and FIG. 24 , in some embodiments, the second anti-shake magnetic member 2114 is fixed to the anti-shake bracket 213 , the second anti-shake coil 2113 is fixed to the base 10 , and the second anti-shake coil 2113 is disposed facing the second anti-shake magnetic member 2114 to drive the anti-shake bracket 213 to move relative to the base 10 in the second direction X. The second anti-shake magnetic member 2114 and the second anti-shake coil 2113 are arranged in the third direction Z. The second anti-shake coil 2113 being disposed facing the second anti-shake magnetic member 2114 means that the winding plane of the second anti-shake coil 2113 faces the second anti-shake magnetic member 2114. For example, the winding plane of the second anti-shake coil 2113 can be disposed parallel to the XY plane.

[0303] For example, a second anti-shake sensor (not shown) fixed to the base 10 can be used to detect a position change of the anti-shake bracket 213 in the second direction X.

[0304] In this embodiment, when the anti-shake bracket 213 moves relative to the base 10 in the second direction X, the movement direction of the anti-shake bracket 213 is perpendicular to the magnetic gap between the second anti-shake magnetic component 2114 and the second anti-shake coil 2113. The above-mentioned magnetic gap is not affected by the movement of the anti-shake bracket 213. Therefore, the problem of a rapid decrease in driving force due to an increase in the magnetic gap can be avoided, thereby ensuring that the anti-shake driving force of the voice coil motor 1 is large and relatively stable, which is conducive to the long-stroke design of the optical image stabilization function of the voice coil motor 1.

[0305] Driven by the first anti-shake magnetic element 2112, the first anti-shake coil 2111, the second anti-shake magnetic element 2114, and the second anti-shake coil 2113, the anti-shake bracket 213 can drive the focus bracket 221 and the lens 2 to move relative to the base 10 in the second direction X and / or the first direction Y, thereby achieving movement in the XY plane. In this case, the voice coil motor 1 can achieve optical image stabilization for the camera module 100. Based on the layout and other related designs of the first anti-shake magnetic element 2112, the first anti-shake coil 2111, the second anti-shake magnetic element 2114, and the second anti-shake coil 2113, the voice coil motor 1 can achieve a long-stroke design for optical image stabilization, providing a better shooting experience.

[0306] In this embodiment, the direction in which the first anti-shake coil 2111 and the first anti-shake magnetic component 2112 drive the anti-shake bracket 213 to move is perpendicular to the direction in which the second anti-shake coil 2113 and the second anti-shake magnetic component 2114 drive the anti-shake bracket 213 to move; in some other embodiments, the direction in which the first anti-shake coil 2111 and the first anti-shake magnetic component 2112 drive the anti-shake bracket 213 to move is perpendicular to the direction in which the second anti-shake coil 2113 and the second anti-shake magnetic component 2114 drive the anti-shake bracket 213 to move but are not perpendicular to each other.

[0307] Exemplarily, the second anti-shake magnetic element 2114 can have two opposite polarity directions, and the polarity direction of the second anti-shake magnetic element 2114 is arranged perpendicular to the winding plane of the second anti-shake coil 2113. The coils in the two sections of the second anti-shake coil 2113 can respectively correspond to the two polarity directions of the second anti-shake magnetic element 2114, and the currents in the coils in the two sections flow in opposite directions. The side of the second anti-shake magnetic element 2114 facing the second anti-shake coil 2113 includes a north pole (N) and a south pole (S), and the side of the second anti-shake magnetic element 2114 facing away from the second anti-shake coil 2113 includes a south pole (S) and a north pole (N) respectively.

[0308] Exemplarily, the second anti-shake magnetic component 2114 may include one or more magnets, and the implementation structure of the second anti-shake magnetic component 2114 may be various. For example, the second anti-shake magnetic component 2114 is a Halbach magnet array. For another example, the second anti-shake magnetic component 2114 may adopt a dual magnet structure, for example, consisting of two magnets, the two magnets are arranged in the second direction X, and the polarity directions are opposite. For example, the second anti-shake magnetic component 2114 may include at least three magnets, and among the three adjacent magnets, the polarization directions of the two magnets located on the edges are opposite and perpendicular to the arrangement direction of the three magnets, and the polarization direction of the magnet located in the middle is directed from one magnet to the other magnet. In other embodiments, the second anti-shake magnetic component 2114 may also adopt a single magnet structure, for example, consisting of a magnet, the magnet includes two parts with opposite polarity directions, and the magnet can be made using a bipolar magnetization process.

[0309] In some embodiments, a second anti-shake magnetic component (not shown) is fixed to the base 10. The second anti-shake magnetic component is arranged facing the second anti-shake magnetic component 2114. The magnetic force between the second anti-shake magnetic component and the second anti-shake magnetic component 2114 causes the anti-shake bracket 213 to move closer to the bottom plate of the base 10.

[0310] As shown in Figures 29 and 30 , the first anti-shake coil 2111, first anti-shake magnetic element 2112, second anti-shake coil 2113, and second anti-shake magnetic element 2114 of the voice coil motor 1 are all roughly arranged in the XY plane. By increasing the width of the magnetic elements (i.e., the dimension of the first anti-shake magnetic element 2112 in the first direction Y and the dimension of the second anti-shake magnetic element 2114 in the second direction X), the motion range of the anti-shake bracket 213 in the first direction Y and / or the second direction X can be increased, facilitating a long-stroke design for optical image stabilization without increasing the height of the voice coil motor 1. Furthermore, since the motion resistance of the voice coil motor 1 during optical image stabilization is primarily due to the sliding friction between the support and mating structural components and is unrelated to the motion range, the resistance does not increase significantly during long-stroke optical image stabilization, thus enabling a long-stroke design for optical image stabilization without significantly increasing the driving force.

[0311] FIG31 is a schematic structural diagram of the focusing bracket 221 and the focusing magnetic conductive member 2223 shown in FIG15 at another angle.

[0312] As shown in FIG31 , in some embodiments, the focus bracket 221 can be generally frame-shaped and have an installation space 2211. The focus bracket 221 is provided with a fourth installation slot 2212 and a second slide slot 2213. The openings of the fourth installation slot 2212 and the second slide slot 2213 can be disposed away from the installation space 2211.

[0313] For example, there are two second sliding shaft grooves 2213, which are located on both sides of the fourth mounting groove 2212. The extension direction of the two second sliding shaft grooves 2213 may be parallel to the third direction Z.

[0314] It is understandable that the installation space 2211 of the focus bracket 221 is used to install the lens 2. Exemplarily, the central axis of the focus bracket 221 is parallel to the optical axis of the lens 2.

[0315] FIG32 is a fifth schematic diagram of a partial structure of the voice coil motor 1 shown in FIG6 in one embodiment.

[0316] As shown in FIG. 31 and FIG. 32 , in some embodiments, the focusing magnetic member 2222 may be installed in the fourth installation slot 2212 of the focusing bracket 221 to be fixed to the focusing bracket 221 .

[0317] As shown in Figures 31 and 32, in some embodiments, the focusing magnetic conductive member 2223 is fixed on the focusing bracket 221 and is arranged opposite to the focusing magnetic member 2222. For example, the focusing magnetic conductive member 2223 can be formed into an integrally formed structural member with the focusing bracket 221 by means of insert-molding or the like. At this time, the focusing magnetic conductive member 2223 is embedded in the focusing bracket 221. In other embodiments, the main part of the focusing magnetic conductive member 2223 can be located between the focusing magnetic member 2222 and the bottom wall of the fourth mounting slot 2212. Among them, the focusing magnetic conductive member 2223 can be fixed to the focusing bracket 221 by means of bonding or the like, and the focusing magnetic member 2222 can be fixed to the focusing magnetic conductive member 2223 by means of bonding or the like.

[0318] Fig. 33 is a sixth schematic diagram of a partial structure of the voice coil motor 1 shown in Fig. 6 in one embodiment. Fig. 34 is a partial cross-sectional view of a portion of the voice coil motor 1 shown in Fig. 33 at position FF in one embodiment.

[0319] As shown in Figures 33 and 34, in some embodiments, the focus bracket 221 is mounted inside the anti-shake bracket 213, with the focus magnetic member 2222 positioned opposite the focus coil 2221. Furthermore, the two second slide slots 2213 of the focus bracket 221 correspond to the two first slide slots 2136 of the anti-shake bracket 213. A portion of one of the third support members 224 is positioned within one of the second slide slots 2213, while a portion of the other third support member 224 is positioned within one of the second slide slots 2213. The walls of the second slide slots 2213 can slide relative to the third support members 224.

[0320] It is understood that the focus bracket 221 is slidably connected to the anti-shake bracket 213 via the third support member 224, and the relative sliding direction between the two is parallel to the guide direction of the third support member 224, that is, the third direction Z. Specifically, when the third support member 224 adopts a sliding shaft structure, the axial direction of the sliding shaft is the guide direction of the third support member 224; when the third support member 224 adopts a ball bearing structure, the arrangement direction of the multiple balls is the guide direction of the third support member 224.

[0321] As shown in Figure 34, the focus coil 2221 is fixed to the anti-shake bracket 213, and the focus magnetic member 2222 is fixed to the focus bracket 221. The focus coil 2221 is arranged facing the focus magnetic member 2222, and is used to drive the focus bracket 221 to move relative to the anti-shake bracket 213 in the third direction Z. When the focus bracket 221 moves relative to the anti-shake bracket 213 in the third direction Z, the focus bracket 221 can drive the lens 2 mounted thereon to move in the third direction Z. At this time, the voice coil motor 1 can achieve automatic focus of the camera module 100. The focus coil 2221 is arranged facing the focus magnetic member 2222, which means that the winding plane of the focus coil 2221 faces the focus magnetic member 2222. For example, a focus sensor 2233 (see figure) fixed to the focus circuit board 2231 can be used to detect position changes of the focus bracket 221 in the third direction Z.

[0322] In this embodiment, during the movement of the focusing bracket 221 relative to the anti-shake bracket 213, the movement direction of the focusing bracket 221 is perpendicular to the magnetic gap between the focusing magnetic member 2222 and the focusing coil 2221. The above-mentioned magnetic gap is not affected by the movement of the focusing bracket 221. Therefore, the problem of a rapid decrease in driving force due to an increase in the magnetic gap can be avoided, thereby ensuring that the focus driving force of the voice coil motor 1 is large and the driving force is relatively stable, which is conducive to the long-stroke design of the focus function of the voice coil motor 1.

[0323] As shown in Figures 32 and 34, the focusing magnetic member 2222 can have two opposite polarity directions, and the polarity direction of the focusing magnetic member 2222 is arranged perpendicular to the winding plane of the focusing coil 2221. Among them, the coils in the two sections of the focusing coil 2221 can be respectively arranged corresponding to the two polarity directions of the focusing magnetic member 2222, and the currents in the coils in the two sections flow in opposite directions. It can be understood that the polarity direction can be the direction of the North Pole (N) toward the South Pole (S), or the direction of the South Pole (S) toward the North Pole (N). At this time, the side of the focusing magnetic member 2222 facing the focusing coil 2221 includes the North Pole (N) and the South Pole (S), and the side of the focusing magnetic member 2222 facing away from the focusing coil 2221 correspondingly includes the South Pole (S) and the North Pole (N).

[0324] Exemplarily, the focusing magnetic member 2222 may include one or more magnets, and the implementation structure of the focusing magnetic member 2222 may be various. For example, in some embodiments, the focusing magnetic member 2222 may adopt a dual magnet solution, for example, consisting of two magnets, the two magnets are arranged in a third direction Z, and the polarity directions are opposite. In other embodiments, the focusing magnetic member 2222 is a Halbach magnet array. In other embodiments, the focusing magnetic member 2222 may adopt a single magnet solution, for example, consisting of a magnet, the magnet including two parts with opposite polarity directions. The magnet can be made using a bipolar magnetization process.

[0325] As shown in Figure 34, in some embodiments, a magnetic attraction force is formed between the focusing magnetic member 2222 and the focusing magnetic suction member 2234, so that the focusing bracket 221 tends to approach the third edge 2131c of the anti-shake bracket 213, and the focusing bracket 221, the third support member 224 and the anti-shake bracket 213 maintain contact. The third support member 224 can better guide the focusing bracket 221 to move along the third direction Z relative to the anti-shake bracket 213.

[0326] As shown in Figures 29, 30, and 34, the focus drive assembly 222 and the anti-shake drive assembly 211 of the voice coil motor 1 are both moving magnet designs. The drive of the voice coil motor 1 in the first direction Y, the second direction X, and the third direction Z is independently controlled by a set of drive components (including coils and magnetic components). Specifically, when the focus bracket 221 of the voice coil motor 1 moves relative to the anti-shake bracket 213 in the third direction Z for autofocus, the relative position of the anti-shake bracket 213 and the base 10 is not affected, and the magnetic gap width of the anti-shake drive assembly is not likely to change. Similarly, when the anti-shake bracket 213 moves relative to the base 10 in the first direction Y and / or the second direction X for optical image stabilization, the focus bracket 221 moves with the anti-shake bracket 213, and the relative position of the two is not affected. The magnetic gap width of the focus drive assembly 222 is not likely to change. Therefore, the focus drive assembly 222 and the anti-shake drive assembly of the voice coil motor 1 are decoupled, and they do not interfere with each other during movement, which helps ensure the driving accuracy of the voice coil motor 1.

[0327] In addition, since the focus bracket 221 is located inside the anti-shake bracket 213, the focus coil 2221 is fixed to the anti-shake bracket 213, and the focus magnetic member 2222 is fixed to the focus bracket 221, the optical image stabilization movable subassembly of the voice coil motor 1 wraps around the focus movable subassembly. It is understandable that when the focus bracket 221 is located inside the anti-shake bracket 213, the anti-shake bracket 213 can be arranged around the focus bracket 221. Surrounding can mean that the anti-shake bracket 213 is arranged around the focus bracket 221, or it can be arranged around a portion of the anti-shake bracket 213 around the focus bracket 221. In this embodiment, the anti-shake bracket 213 is ring-shaped. In this case, the anti-shake bracket 213 is arranged around the focus bracket 221.

[0328] It will be appreciated that in some embodiments, the anti-shake bracket 213 is located inside the focus bracket 221. In this case, when the camera module 100 needs to focus, the focus bracket 221 needs to drive the anti-shake bracket 213 and the lens 2 in the third direction. This makes the actuator composed of the focus bracket 221, the anti-shake bracket 213, and the lens 2 relatively heavy, requiring the focus drive assembly 222 to increase its size to increase its driving force. Therefore, this arrangement is detrimental to the lightweight and compact design of the voice coil motor 1. In this embodiment, the focus bracket 221 is located inside the anti-shake bracket 213. In this case, when the camera module 100 needs to focus, the focus bracket 221 needs to drive the lens 2 in the third direction Z. This allows the anti-shake bracket 213 to be omitted from the actuator during the focusing process. This means that the actuator composed of the focus bracket 221 and the lens 2 is relatively lightweight, facilitating the compact design of the focus drive assembly 222. The voice coil motor 1 of this embodiment can be lightweight and compact.

[0329] It can be understood that, compared to the solution where the anti-shake bracket 213 is located inside the focus bracket 221, the anti-shake bracket 213 requires at least two anti-shake drive assemblies to propel the anti-shake bracket 213 in the XY plane. Consequently, the voice coil motor 1 requires at least two sets of wiring to provide signals and power to the anti-shake drive assemblies. Furthermore, at least two sets of wiring must pass through the focus bracket 221. Therefore, this solution's power supply configuration is relatively complex, increasing the difficulty of setting up the voice coil motor 1. In contrast, this embodiment places the focus bracket 221 inside the anti-shake bracket 213. Since the focus bracket 221 requires a set of focus drive assemblies 222 to propel it in the third direction Z, the voice coil motor 1 also requires a set of wiring to provide signals and power to the focus drive assemblies 222. This wiring also requires a set of wiring to pass through the anti-shake bracket 213. Therefore, the power supply configuration of this embodiment is relatively simple, significantly reducing the difficulty of setting up the voice coil motor 1.

[0330] As shown in FIG34 , the plane on which the wire of the focus coil 2221 is wound (i.e., the winding plane) can be parallel to the third direction Z. In this case, the focus coil 2221 is arranged vertically, so that the focus coil 2221 can occupy a smaller area in the XY plane, which is beneficial to the miniaturization of the voice coil motor 1. The focus magnetic member 2222 can include two opposite polarity directions, both of which are perpendicular to the third direction Z. In this case, the focus magnetic member 2222 can be arranged vertically, thereby reducing the space occupied by the focus magnetic member 2222 in the XY plane, facilitating the miniaturization design of the voice coil motor 1.

[0331] FIG. 35 is a partially exploded view of the voice coil motor 1 shown in FIG. 6 in one embodiment.

[0332] As shown in FIG. 35, by way of example, the limiting bracket 23 includes a top plate member 231 and side frames 232. The side frames 232 are connected to the periphery of the top plate member 231. In the present embodiment, the side frames 232 are integrally formed with the top plate member 231. In other embodiments, the side frames 232 can also be connected to the periphery of the top plate member 231 by other processes (such as welding, bonding or snap-fitting, etc.).

[0333] By way of example, the top plate member 231 includes a first plate member 2311, a second plate member 2312, and a third plate member 2313 that are connected in sequence. Among them, the first plate member 2311 of the top plate member 231 is disposed opposite to the third plate member 2313. The top plate member 231 is generally in a "C" shape.

[0334] By way of example, the side frames 232 include a first side portion 2321 and a second side portion 2322. Among them, the first side portion 2321 can be connected between the first plate member 2311 and the third plate member 2313. The second side portion 2322 can be connected to the periphery of the third plate member 2313.

[0335] By way of example, the first side portion 2321 is provided with first mounting holes 2323. The number of the first mounting holes 2323 is two. The two first mounting holes 2323 are spaced apart on both sides of the first side portion 2321. The shape of the first mounting holes 2323 is a rectangular hole. In other embodiments, the number, shape, and position of the first mounting holes 2323 are not specifically limited.

[0336] By way of example, the first mounting holes 2323 include a first hole wall 2331 and a second hole wall 2332 that are disposed opposite to each other, and a third hole wall 2333 and a fourth hole wall 2334 that are disposed opposite to each other. Among them, the third hole wall 2333 and the fourth hole wall 2334 of the first mounting holes 2323 are connected between the first hole wall 2331 and the second hole wall 2332 of the first mounting holes 2323.

[0337] By way of example, the second side portion 2322 is provided with second mounting holes 2324. The number of the second mounting holes 2324 is two. The two second mounting holes 2324 are spaced apart on both sides of the second side portion 2322. The shape of the second mounting holes 2324 is a rectangular hole. In other embodiments, the number, shape, and position of the second mounting holes 2324 are not specifically limited.

[0338] By way of example, the second mounting holes 2324 include a first hole wall 2335 and a second hole wall 2336 that are disposed opposite to each other, and a third hole wall 2337 and a fourth hole wall 2338 that are disposed opposite to each other. Among them, the third hole wall 2337 and the fourth hole wall 2338 of the second mounting holes 2324 are connected between the first hole wall 2335 and the second hole wall 2336 of the second mounting holes 2324.

[0339] As shown in Figure 35 , the anti-shake bracket 213 exemplarily includes two first mounting blocks 241. The two first mounting blocks 241 are spaced apart and located on either side of the third side 2131c of the anti-shake bracket 213. The first mounting blocks 241 are rectangular. In other embodiments, the number, shape, and location of the first mounting blocks 241 are not specifically limited.

[0340] Exemplarily, the first mounting block 241 includes a first side surface 2411 and a second side surface 2412 disposed opposite to each other, and a third side surface 2413 and a fourth side surface 2414 disposed opposite to each other. The third side surface 2413 and the fourth side surface 2414 of the first mounting block 241 are connected between the first side surface 2411 and the second side surface 2412 of the first mounting block 241.

[0341] As shown in FIG35 , the anti-shake bracket 213 illustratively includes two second mounting blocks 242 . The two second mounting blocks 242 are spaced apart and located on either side of the fourth side 2131 d of the anti-shake bracket 213 . The second mounting blocks 242 are rectangular in shape. In other embodiments, the number, shape, and location of the second mounting blocks 242 are not specifically limited.

[0342] Exemplarily, the second mounting block 242 includes a first side surface 2421 and a second side surface 2422 disposed opposite to each other, and a third side surface 2423 and a fourth side surface 2424 disposed opposite to each other. The third side surface 2423 and the fourth side surface 2424 of the second mounting block 242 are connected between the first side surface 2421 and the second side surface 2422 of the second mounting block 242.

[0343] FIG36 is a seventh schematic diagram of a partial structure of the voice coil motor 1 shown in FIG6 in one embodiment.

[0344] As shown in FIG36 , the limit bracket 23 is fixed to the side of the anti-shake bracket 213 facing away from the base 10. The limit bracket 23 and the anti-shake bracket 213 can cooperate to limit the movement of the focus bracket 221 in the third direction Z, thereby preventing the focus bracket 221 from separating from the limit bracket 23 and making the relative movement between the focus bracket 221 and the limit bracket 23 more reliable.

[0345] For example, the top plate 231 is fixed to the top surface of the anti-shake bracket 213. The first side portion 2321 is fixed to the side of the third side portion 2131c of the anti-shake bracket 213. The second side portion 2322 is fixed to the side of the fourth side portion of the anti-shake bracket. In this way, the first side portion 2321 and the second side portion 2322 are respectively fixed to the side of two adjacent sides of the anti-shake bracket 213.

[0346] For example, the limiting bracket 23 can be fixedly connected to the insulating body 2131 (see Figure 21) of the anti-shake bracket 213 using adhesive. Alternatively, the limiting bracket 23 can be fixedly connected to the metal insert 2132 (see Figure 21) of the anti-shake bracket 213 by welding. This provides a more secure connection between the limiting bracket 23 and the anti-shake bracket 213, thereby preventing the limiting bracket 23 from falling off the anti-shake bracket 213.

[0347] For example, the limiting bracket 23 may be fixedly connected to the third support member 224 (see FIG. 34 ) by welding. This provides a more secure connection between the third support member 224 and the anti-shake bracket 213, thereby preventing the third support member 224 (see FIG. 34 ) and the anti-shake bracket 213 from falling off or tilting.

[0348] Illustratively, the first plate 2311 of the top plate 231 of the position-limiting bracket 23 is disposed corresponding to the second edge 2131b of the anti-shake bracket 213. The second plate 2312 of the top plate 231 of the position-limiting bracket 23 is disposed corresponding to the first edge 2131a of the anti-shake bracket 213. The third plate 2313 of the top plate 231 of the position-limiting bracket 23 is disposed corresponding to the fourth edge 2131d of the anti-shake bracket 213.

[0349] 36 and FIG35 , the first mounting block 241 of the anti-shake bracket 213 is located in the first mounting hole 2323 of the position limiting bracket 23 , and the second mounting block 242 of the anti-shake bracket 213 is located in the second mounting hole 2324 of the position limiting bracket 23 .

[0350] Illustratively, the first side surface 2411 of the first mounting block 241 is disposed opposite the first hole wall 2331 of the first mounting hole 2323. The second side surface 2412 of the first mounting block 241 is disposed opposite the second hole wall 2332 of the first mounting hole 2323. The third side surface 2413 of the first mounting block 241 is disposed opposite the third hole wall 2333 of the first mounting hole 2323. The fourth side surface 2414 of the first mounting block 241 is disposed opposite the fourth hole wall 2334 of the first mounting hole 2323.

[0351] Illustratively, the first side surface 2421 of the second mounting block 242 is disposed opposite the first hole wall 2335 of the second mounting hole 2324. The second side surface 2422 of the second mounting block 242 is disposed opposite the second hole wall 2336 of the second mounting hole 2324. The third side surface 2423 of the second mounting block 242 is disposed opposite the third hole wall 2337 of the second mounting hole 2324. The fourth side surface 2424 of the second mounting block 242 is disposed opposite the fourth hole wall 2338 of the second mounting hole 2324.

[0352] In one embodiment, the first mounting block 241 of the anti-shake bracket 213 is tightly fitted with the first mounting hole 2323 of the limiting bracket 23, and the second mounting block 242 of the anti-shake bracket 213 is tightly fitted with the second mounting hole 2324 of the limiting bracket 23, thereby ensuring a stable connection between the limiting bracket 23 and the anti-shake bracket 213. It is understood that in this embodiment, during the assembly process of the limiting bracket 23 and the anti-shake bracket 213, in order to ensure that the first mounting block 241 of the anti-shake bracket 213 is tightly fitted with the first mounting hole 2323 of the limiting bracket 23, and the second mounting block 242 of the anti-shake bracket 213 is tightly fitted with the second mounting hole 2324 of the limiting bracket 23, the limiting bracket 23 needs to be assembled onto the anti-shake bracket 213 from the top along the third direction Z. At this time, during the assembly process, the first side portion 2321 of the limiting bracket 23 can easily press against the first mounting block 241 of the anti-shake bracket 213, and the second side portion 2322 of the limiting bracket 23 can easily press against the second mounting block 242 of the anti-shake bracket 213, thereby increasing the difficulty of assembling the limiting bracket 23 and the anti-shake bracket 213 on the one hand, and easily causing the limiting bracket 23 to deform due to extrusion on the other hand, and there is a risk that the deformation cannot be restored. Even if the limiting bracket 23 is assembled on the anti-shake bracket 213, the position of the limiting bracket 23 is difficult to locate, which is not conducive to subsequent welding operations. Based on this problem, the present application proposes a structure of a limiting bracket 23 and an anti-shake bracket 213 to facilitate the assembly of the limiting bracket 23 and the anti-shake bracket 213, and the limiting bracket 23 is not easily deformed. The details are as follows.

[0353] As shown in Figure 35, the top plate 231 is provided with positioning holes 2325. Exemplarily, there are two positioning holes 2325. Positioning holes 2325 are cylindrical in shape. Positioning holes 2325 are located on the second plate 2312 of the top plate 231. In other embodiments, the number, shape, and location of positioning holes 2325 are not specifically limited.

[0354] As shown in Figure 35, the anti-shake bracket 213 includes a positioning block 243. Exemplarily, the number of the positioning blocks 243 is two. The two positioning blocks 243 are respectively and spaced apart and protruded from the top surface of the first side 2131a of the anti-shake bracket 213. The top surface of the first side 2131a is the surface of the first side 2131a facing away from the guide bracket 212. The shape of the positioning block 243 is cylindrical. In other embodiments, the number, position and shape of the positioning holes 2325 are not specifically limited. For example, the two positioning blocks 243 are respectively and spaced apart and protruded from the top surface of the second side 2131b of the anti-shake bracket 213.

[0355] As shown in FIG35 , by way of example, in the second direction X, the distance between the first hole wall 2331 and the second hole wall 2332 of the first mounting hole 2323 is a first distance (i.e., the size of the first mounting hole 2323 in the second direction X). The distance between the first side surface 2411 and the second side surface 2412 of the first mounting block 241 is a second distance (i.e., the size of the first mounting block 241 in the second direction X). The height of the second mounting block 242 is a first height (i.e., the size of the second mounting block 242 in the second direction X).

[0356] The first distance is greater than or equal to the sum of the second distance and the first height.

[0357] As shown in FIG35 , by way of example, in the third direction Z, the distance between the third hole wall 2333 and the fourth hole wall 2334 of the first mounting hole 2323 is the third distance (i.e., the dimension of the first mounting hole 2323 in the third direction Z). In the third direction Z, the distance between the third side surface 2413 and the fourth side surface 2414 of the first mounting block 241 is the fourth distance (i.e., the dimension of the first mounting block 241 in the third direction Z). In the third direction Z, the height of the positioning block 243 is the second height (i.e., the dimension of the positioning block 243 in the third direction Z).

[0358] The third distance is greater than or equal to the sum of the fourth distance and the second height.

[0359] As shown in FIG35 , illustratively, in the third direction Z, the distance between the third hole wall 2337 and the fourth hole wall 2338 of the second mounting hole 2324 is a fifth distance (i.e., the dimension of the second mounting hole 2324 in the third direction Z). The distance between the third side surface 2423 and the fourth side surface 2424 of the second mounting block 242 is a sixth distance (i.e., the dimension of the second mounting block 242 in the third direction Z). The fifth distance is greater than or equal to the sum of the sixth distance and the second height.

[0360] It will be appreciated that during the assembly process of the position-limiting bracket 23 and the anti-shake bracket 213, the position-limiting bracket 23 can first be moved relative to the anti-shake bracket 213 in the second direction X so that the first mounting block 241 is assembled into the first mounting hole 2323. The position-limiting bracket 23 can then be moved relative to the anti-shake bracket 213 in the first direction Y so that the second mounting block 242 is assembled into the second mounting hole 2324. The position-limiting bracket 23 can then be moved relative to the anti-shake bracket 213 in the third direction Z so that the positioning block 243 is inserted into the positioning hole 2325. Finally, glue is filled into the first mounting hole 2323 and the second mounting hole 2324 so that the first mounting block 241 is glued to the wall of the first mounting hole 2323 and the second mounting block 242 is glued to the wall of the second mounting hole 2324, thereby ensuring a stable connection between the position-limiting bracket 23 and the anti-shake bracket 213. It is understandable that, during the assembly process of the position-limiting bracket 23 and the anti-shake bracket 213 in this embodiment, the position-limiting bracket 23 can be prevented from being deformed due to extrusion.

[0361] It can be understood that this embodiment can stably connect the limit bracket 23 and the anti-shake bracket 213 through the cooperation between the first mounting block 241 and the first mounting hole 2323, the cooperation between the second mounting block 242 and the second mounting hole 2324, and the cooperation between the positioning block 243 and the positioning hole 2325.

[0362] The above description specifically introduces several embodiments of the voice coil motor 1 in conjunction with the relevant drawings. The following description specifically introduces several embodiments of the voice coil motor 1 and the module circuit board 3 in conjunction with the relevant drawings.

[0363] FIG37 is a partial cross-sectional view of the camera module 100 shown in FIG3 in one embodiment.

[0364] As shown in Figure 37, for example, the module circuit board 3 is provided with a first avoidance space 3b. The opening of the first avoidance space 3b is located on the surface of the module circuit board 3 facing the base 10. The first avoidance space 3b can be a groove structure or a hole structure.

[0365] The insulating body 2131 of the anti-shake bracket 213 includes a fixing portion 126 . One end of the third support member 224 is fixed to the fixing portion 126 . In this embodiment, a fixing hole 2137 for plugging into the third support member 224 is located on the fixing portion 126 .

[0366] Furthermore, the metal member 12 of the base 10 includes a sunken portion 124. The sunken portion 124 is disposed opposite the fixed portion 126. The sunken portion 124 descends toward the first escape space 3b and is located within the first escape space 3b. The sunken portion 124 encloses a second escape space 125. The second escape space 125 is configured to accommodate at least a portion of the fixed portion 126. In other words, at least a portion of the fixed portion 126 is located within the second escape space 125.

[0367] It will be appreciated that in this embodiment, by first providing a first escape space 3b in the module circuit board 3, the sunken portion 124 can sink into the first escape space 3b and be located within the first escape space 3b, thereby enclosing a second escape space 125. Subsequently, the fixing portion 126 of the anti-shake bracket 213, which is fixedly connected to one end of the third support member 224, is positioned within the second escape space 125, thereby freeing up space between the module circuit board 3 and the third support member 224. This freed-up space can be used to increase the length of the third support member 224. In this way, this embodiment improves the overall strength of the base 10 through the metal member 12. While not occupying the space between the module circuit board 3 and the third support member 224, the length of the third support member 224 can also be significantly increased. The longer third support member 224 significantly improves the stability of the focus bracket 221, making it less likely to tip over.

[0368] It is understood that when the third support member 224 is tilted at a first angle along a certain direction with its bottom as a fixed point, the tilt distance at the top of the longer third support member 224 is shorter, while the tilt distance at the top of the shorter third support member 224 is longer. Therefore, compared with the shorter third support member 224, the longer third support member 224 has better guidance accuracy. The longer third support member 224 of this embodiment provides better guidance accuracy.

[0369] Fig. 38 is a schematic diagram of a portion of the structure of the driving mechanism 20 shown in Fig. 6 in one embodiment. Fig. 39 is a schematic diagram of a portion of the structure of the driving mechanism 20 shown in Fig. 38 at another angle.

[0370] As shown in Figures 38 and 39, in some embodiments, the fourth side 2131d of the anti-shake bracket 213 further includes a first connecting hole 127a and a second connecting hole 127b spaced apart from each other. The first connecting hole 127a and the second connecting hole 127b extend through the fourth side 2131d in the second direction X. In this case, the first connecting hole 127a and the second connecting hole 127b connect the movable space 2133 to the exterior of the anti-shake bracket 213. The first connecting hole 127a is located between one of the first slide shaft grooves 2136 and the first mounting groove 2135a. The second connecting hole 127b is located between the other first slide shaft groove 2136 and the third mounting groove 2135c.

[0371] FIG40 is a schematic diagram of a partial structure of the driving mechanism 20 shown in FIG39 in one embodiment.

[0372] 39 and 40 , for example, the first end 128a of the first conductive member 2138a and the first end 128b of the second conductive member 2138b extend into the first connecting hole 127a. The first end 128c of the first conductive member 2138a and the first end 128d of the second conductive member 2138b may be spaced apart.

[0373] In addition, the first end 128c of the third conductive member 2138c and the first end 128d of the fourth conductive member 2138d extend into the second connecting hole 127b. The first end 128c of the third conductive member 2138c and the first end 128d of the fourth conductive member 2138d may be spaced apart.

[0374] It will be appreciated that the anti-shake bracket 213 of this embodiment is provided with both the first connecting hole 127a and the second connecting hole 127b. In other embodiments, the anti-shake bracket 213 may be provided with only the first connecting hole 127a or the second connecting hole 127b. In this case, the first end 128a of the first conductive member 2138a and the first end 128b of the second conductive member 2138b extend into the first connecting hole 127a, or the first end 128c of the third conductive member 2138c and the first end 128d of the fourth conductive member 2138d extend into the second connecting hole 127b.

[0375] As shown in Figures 38 to 40, by way of example, the first end 128a of the first conductive member 2138a can be electrically connected to the negative power supply terminal of the focus driver chip 2232 via the focus circuit board 2231. The first end 128b of the second conductive member 2138b can be electrically connected to the positive power supply terminal of the focus driver chip 2232 via the focus circuit board 2231. The first end 128c of the third conductive member 2138c can be electrically connected to the SDA terminal of the I2C signal of the focus driver chip 2232 via the focus circuit board 2231. The first end 128d of the fourth conductive member 2138d can be electrically connected to the SCL terminal of the I2C signal of the focus driver chip 2232 via the focus circuit board 2231. In other embodiments, the first conductive member 2138a, the second conductive member 2138b, the third conductive member 2138c, and the fourth conductive member 2138d can also serve as transmission channels for other functions. This application does not limit this in detail.

[0376] FIG41 is a schematic diagram of the partial structure of the driving mechanism 20 shown in FIG38 at another angle.

[0377] 41 and in combination with FIG40 , illustratively, the wall of the first communication hole 127a is provided with a first isolation groove 131. The first isolation groove 131 is located between the first end 128a of the first conductive member 2138a and the first end 128b of the second conductive member 2138b.

[0378] It is understandable that when the anti-shake bracket 213 is carbonized at high temperature, the first isolation groove 131 can prevent a micro short circuit from occurring between the first end 128a of the first conductive member 2138a and the first end 128b of the second conductive member 2138b.

[0379] 41 and in combination with FIG40 , illustratively, the wall of the second communication hole 127b is provided with a second isolation groove 141. The second isolation groove 141 is located between the first end 128c of the third conductive member 2138c and the first end 128d of the fourth conductive member 2138d.

[0380] It is understandable that when the anti-shake bracket 213 is carbonized at high temperature, the second isolation groove 141 can prevent a micro short circuit from occurring between the first end 128 c of the third conductive member 2138 c and the first end 128 d of the fourth conductive member 2138 d.

[0381] FIG42 is a schematic diagram of a partial structure of the camera module 100 shown in FIG3 in some embodiments.

[0382] As shown in FIG42 , in some embodiments, the camera module 100 includes a plurality of second reeds 132. This embodiment illustrates that the number of the second reeds 132 is four. In other embodiments, the number of the second reeds 132 is not specifically limited.

[0383] The arrangement plane of the multiple second springs 132 can be perpendicular to the third direction Z and located on the side of the anti-shake bracket 213 facing away from the module circuit board 3. That is, the multiple second springs 132 can be arranged in the XY plane. Some second springs 132 connect the first side 2131a of the anti-shake bracket 213 to the base 10, while other second springs 132 connect the second side 2131b of the anti-shake bracket 213 to the base 10. The multiple second springs 132 can be arranged in the space above the first side 2131a and second side 2131b of the anti-shake bracket 213 to improve space utilization in the camera module 100. The multiple second springs 132 can provide an elastic force to return the anti-shake bracket 213 to its equilibrium position when it moves relative to the base 10 and leaves the equilibrium position. In some embodiments, the second springs 132 can be made of a conductive material to ensure signal transmission.

[0384] Furthermore, as shown in conjunction with Figures 38 and 40 , the first conductive member 2138a, the second conductive member 2138b, the third conductive member 2138c, and the fourth conductive member 2138d of the anti-shake bracket 213 can be electrically connected to the plurality of second reeds 132 in a one-to-one correspondence, and are electrically connected to the module circuit board 3 via the plurality of second reeds 132 and the conductive members of the base 10. In this way, the focus driver chip 2232 can be electrically connected to the module circuit board 3 via the focus circuit board 2231, the first conductive member 2138a, the second conductive member 2138b, the third conductive member 2138c, the fourth conductive member 2138d of the anti-shake bracket 213, the plurality of second reeds 132, and the conductive members of the base 10.

[0385] FIG43 is a schematic diagram of a partial structure of the camera module 100 shown in FIG3 in some embodiments.

[0386] As shown in Figure 43, in some embodiments, the camera module 100 includes a plurality of first reeds 133. The arrangement plane of the plurality of first reeds 133 can be perpendicular to the third direction Z, and be located on the side of the focusing bracket 221 facing away from the module circuit board 3. That is, the plurality of first reeds 133 can be arranged in the XY plane. The plurality of first reeds 133 connect the anti-shake bracket 213 and the focusing bracket 221. Among them, the plurality of first reeds 133 are used to provide an elastic force to move the focusing bracket 221 back to the equilibrium position when the focusing bracket 221 moves relative to the anti-shake bracket 213 and leaves the equilibrium position. In some embodiments, the first reeds 133 can be made of conductive material to take into account the signal transmission function.

[0387] Illustratively, the plurality of first reeds 133 include a first sub-reed 1331 , a second sub-reed 1332 , a third sub-reed 1333 and a fourth sub-reed 1334 that are spaced apart.

[0388] For example, the first sub-reed 1331 can serve as a transmission channel for the negative power supply of the driver chip of the variable aperture 7. The second sub-reed 1332 can serve as a transmission channel for the positive power supply of the driver chip of the variable aperture 7. The third sub-reed 1333 can serve as a transmission channel for the SDA signal of the driver chip of the variable aperture 7. The fourth sub-reed 1334 can serve as a transmission channel for the SCL signal of the driver chip of the variable aperture 7.

[0389] As shown in Figures 38 and 40, by way of example, the first sub-spring 1331, the second sub-spring 1332, the third sub-spring 1333 and the fourth sub-spring 1334 can be electrically connected one-to-one to the first conductive member 2138a, the second conductive member 2138b, the third conductive member 2138c and the fourth conductive member 2138d of the anti-shake bracket 213, and electrically connected to the module circuit board 3 through multiple second springs 132 and the conductive members of the base 10.

[0390] As shown in FIG43 , the first sub-spring 1331 and the second sub-spring 1332 are disposed adjacent to each other. FIG43 illustrates that the first sub-spring 1331 and the second sub-spring 1332 are located on the same side of the focus bracket 221 and are disposed close to the first edge 2131a of the anti-shake bracket 213 .

[0391] A portion of the first sub-spring 1331 is recessed away from the second sub-spring 1332 to form a first recessed area 134a. A portion of the second sub-spring 1332 is recessed away from the first sub-spring 1331 to form a second recessed area 134b. The first and second recessed areas 134a and 134b define a first adhesive dispensing space 134. A first adhesive material 135 is disposed within the first adhesive dispensing space 134. The first adhesive material 135 connects the first sub-spring 1331 and the second sub-spring 1332.

[0392] It will be appreciated that the first adhesive material 135 connecting the first and second sub-springs 1331, 1332 prevents them from shaking, thereby improving the stability of the connection between them. Furthermore, compared to a case where the first and second sub-springs 1331, 1332 are arranged parallel to each other to form a glue dispensing space, the volume of the glue dispensing space in this embodiment is larger. This prevents glue from overflowing onto the side of the first sub-spring 1331 facing away from the second sub-spring 1332 during the glue dispensing process. Furthermore, during the focusing process of the focusing bracket 221, the first adhesive material 135 is less likely to become debonded due to collision with the focusing bracket 221. This embodiment provides a more stable and reliable connection between the first and second sub-springs 1331, 1332. Furthermore, during the glue dispensing process, glue is less likely to overflow onto the side of the second sub-spring 1332 facing away from the first sub-spring 1331. At this time, during the anti-shake process of the anti-shake bracket 213 , the first adhesive 135 is not easily debonded due to collision with the anti-shake bracket 213 . In this embodiment, the connection between the first sub-spring 1331 and the second sub-spring 1332 is more stable and reliable.

[0393] As shown in Figure 43, the third and fourth sub-springs 1333 and 1334 are positioned adjacent to each other. Figure 43 illustrates that the third and fourth sub-springs 1333 and 1334 are located on the same side of the focus bracket 221, and are positioned near the third edge 2131c of the anti-shake bracket 213. It is understood that the connection between the third and fourth sub-springs 1333 and 1334 can be similar to the connection between the first and second sub-springs 1331 and 1332. Details will not be repeated here.
