Description

Technical Field

[0001] The present application belongs to the technical field of camera modules, and in particular, relates to an anti-shake focus driver and a camera module. Background Art

[0002] The optical image stabilization mechanism of the camera module mainly reduces the problem of blurred images caused by factors such as shaking by moving the optical elements of the camera module; among them, the optical image stabilization mechanism can be divided into two anti-shake compensation modes: lens movement and image sensor movement. In the anti-shake mechanism based on the lens movement anti-shake principle, a lens translation mechanism is usually provided to drive the lens to translate in a plane parallel to the plane where the image sensor is located to achieve translational anti-shake compensation. At the same time, since the lens also needs to move along the optical axis to focus, a focusing mechanism will also be connected to the lens to drive the lens to move in the direction of the optical axis of the image sensor.

[0003] Usually, the focus mechanism is connected to the lens as a whole, and then the focus mechanism and the lens are placed on the moving parts of the anti-shake mechanism as a whole to realize the integrated installation of the focus and anti-shake functional structures, which makes the anti-shake mechanism load heavier, and increases the difficulty of controlling the anti-shake movement accuracy to a certain extent, making the anti-shake effect unsatisfactory. On the other hand, the focus and anti-shake drive mechanisms mostly adopt the mode of magnets and coils, and generate a variable magnetic field that interacts with the magnetic field of the magnet by passing a controllable direct current into the coil, thereby driving the movement of the moving parts in the focus and anti-shake mechanisms; generally speaking, in order to facilitate the configuration of electrical signals and reduce the difficulty of arranging conductive lines and the risk of mutual interference, passive components such as magnets are usually concentrated on the lens, which further increases the overall weight of the lens and the components mounted thereon, and further increases the load of the moving part of the anti-shake mechanism, which also aggravates the difficulty of controlling the anti-shake movement accuracy to a certain extent.

[0054] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0055] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0056] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0057] The focus mechanism and anti-shake mechanism of some camera modules respectively drive the lens to move along the optical axis direction of the lens and the orthogonal direction of the optical axis to achieve focus and anti-shake compensation operations, thereby obtaining high-quality shooting images. Usually, in order to reduce the volume specifications of the module, the focus mechanism and the anti-shake mechanism are often integrated to a certain extent, such as directly connecting the focus mechanism to the lens, and then installing the focus mechanism on the moving part of the anti-shake mechanism, so that the lens and the connected anti-shake mechanism and focus mechanism are installed in the module as a whole based on the anti-shake mechanism. However, this integrated structure requires the moving part of the anti-shake mechanism to bear the weight of the lens and the focus mechanism, which increases the difficulty of controlling the motion accuracy of the moving part of the anti-shake mechanism to a certain extent, which increases the risk of fluctuations in the anti-shake effect and reduces the stability and reliability of the anti-shake operation.

[0058] To this end, the embodiments of the present application provide an anti-shake focus driver and a camera module, which are intended to reduce the load on the moving parts of the anti-shake mechanism of the camera module based on the lens movement anti-shake principle to a certain extent, so as to improve the anti-shake and focus operation accuracy, thereby improving the anti-shake and focus quality and maintaining the anti-shake stability and reliability.

[0059] Figure 1 A schematic diagram of the structure of an anti-shake focus driver in an embodiment of the present application is shown; Figure 2 Shows Figure 1 A schematic diagram of the structure of an anti-shake driving component of an anti-shake focus driver; Figure 3 Shows Figure 2 Schematic diagram of the electrical connection structure of the anti-shake drive component.

[0060] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 , Fig. 9 and Fig.11 In some embodiments, the anti-shake focus driver is used to move the lens to achieve focus and anti-shake operations of the camera module; the anti-shake focus driver can be configured to be directly connected to the lens to achieve focus movement of the lens in the direction along the optical axis F of the camera module, and to achieve anti-shake movement of the lens in the orthogonal plane of the optical axis F. It is worth noting that in order to avoid unclear definitions and considering the defect that this application mainly aims at achieving focus and anti-shake operations by lens movement, the optical axis F mentioned in the embodiments of this application is the optical axis of the lens of the camera module.

[0061] Specifically, the anti-shake focus driver may include a focus base 1, an anti-shake base 2, a focus drive component 3, an anti-shake carrier 4, an anti-shake drive component 5, and a drive circuit 6; wherein the anti-shake carrier 4, the anti-shake base 2, and the anti-shake drive component 5 cooperate to form an anti-shake module to achieve an anti-shake function, and the anti-shake module is used to carry the lens to move in an orthogonal plane to the optical axis F to achieve anti-shake movement. The anti-shake base 2, the focus drive component 3, and the focus base 1 cooperate to form a focus module to achieve a focus function, and the focus module is used to carry the anti-shake carrier 4, the anti-shake base 2, the anti-shake drive component 5, and the lens to move together along the direction of the optical axis F to achieve focus movement. It is worth noting that, in order to facilitate the passage of light, a first light-transmitting window 21 is provided on the anti-shake base 2, a second light-transmitting window 41 is provided on the anti-shake carrier 4, and a third light-transmitting window 11 is provided on the focusing base 1, and the first light-transmitting window 21, the second light-transmitting window 41 and the third light-transmitting window 11 can be arranged relatively to each other, and the lens is matched and installed on the anti-shake carrier 4, and the light output end of the lens is matched and connected with the second light-transmitting window, so that the lens can be stably introduced into the camera module, and the focusing and anti-shake functions based on lens movement can be realized.

[0062] The focus base 1 is the basic bearing component of the anti-shake focus actuator, and is the basis for the focus and anti-shake operations of the anti-shake focus actuator, that is, the movement of the lens along the optical axis F and in the direction orthogonal to the optical axis F is implemented relative to the focus base 1. The focus base 1 is also the installation base of the anti-shake focus actuator, and can be installed in the camera module through the focus base 1.

[0063] The anti-shake base 2 is a mover for the focusing operation, which is movably connected to the focusing base 1, and the moving direction is the direction of the optical axis F; and the anti-shake base 2 is also the basic carrier of the anti-shake function mechanism, and is internally configured with a cavity for accommodating the anti-shake function mechanism, which is used to install the anti-shake carrier 4, the anti-shake drive assembly 5 and the lens, so that the anti-shake carrier 4, the anti-shake drive assembly 5 and the lens can be moved along the direction of the optical axis by the anti-shake base 2 to realize the focusing operation.

[0064] The focus driving assembly 3 is connected between the focus base 1 and the anti-shake base 2 to provide a driving force to directly drive the anti-shake base 2 to reciprocate along the direction of the optical axis F relative to the focus base 1 .

[0065] The anti-shake carrier 4 is a mover for anti-shake operation, which can move relative to the anti-shake base 2 in a plane orthogonal to the optical axis F, and the anti-shake carrier 4 is configured as a lens mounting carrier, carrying the lens to move in a plane orthogonal to the optical axis F to achieve anti-shake operation.

[0066] The anti-shake driving component 5 is connected between the anti-shake carrier 4 and the anti-shake base 2, and provides a driving force to directly drive the anti-shake carrier 4 to reciprocate relative to the anti-shake base 2 along multiple directions orthogonal to the optical axis F. Generally speaking, the anti-shake driving component 5 may include an anti-shake magnet 51 and an anti-shake coil 52 that are relatively arranged, the anti-shake magnet 51 may be arranged on the anti-shake base 2, and the anti-shake coil 52 may be arranged on the anti-shake carrier 4, so that the direction and magnitude of the force applied to the energized anti-shake coil 52 in the magnetic field of the anti-shake magnet 51 can be adjusted by adjusting the magnitude and direction of the current loaded on the anti-shake coil 52, thereby driving the anti-shake carrier 4 to translate in a plane orthogonal to the optical axis F.

[0067] Among them, the relatively heavy anti-shake magnet 51 can be arranged on the anti-shake base 2, and the relatively light anti-shake coil 52 can be arranged on the anti-shake carrier 4, so that the anti-shake carrier 4 can only carry the lens and the anti-shake coil 52, so as to achieve a relatively low load, thereby reducing the difficulty of controlling the high-frequency anti-shake movement accuracy to a certain extent, and facilitating the maintenance of a good anti-shake effect and stability; at the same time, since the load of the anti-shake carrier 4 is reduced, the demand for anti-shake driving force can also be relatively reduced, thereby reducing the specifications and performance configuration requirements of the anti-shake coil 52 and the anti-shake magnet 51 to a certain extent. It is worth noting that although the load of the focus module is increased by carrying the anti-shake module and the lens through the focus module, considering that the moving part of the focus module mainly moves back and forth in the direction of the optical axis F and the action frequency is lower than the anti-shake action frequency, it will not cause a significant adverse effect on the focus quality, and the influence of the increased load can be weakened by slightly increasing the focus driving power; thereby the focus quality can be maintained as a whole and the anti-shake quality can be improved.

[0068] The driving circuit 6 is a driving execution element for anti-shake and focus operations, and is respectively connected to the anti-shake coil 52 and the focus driving component 3, so as to load the control signals sent by the external control unit onto the anti-shake coil 52 and the focus driving component 3, respectively, to control the movement direction and amplitude of the anti-shake base 2 and the anti-shake carrier 4.

[0069] In the embodiment of the present application, the anti-shake base is set as a mover that can move along the optical axis, and carries the anti-shake carrier, the anti-shake drive component and the lens, so that the anti-shake function structure is integrated into the focus function mechanism, and the integrated multiplexing of the focus and anti-shake functions and structures is realized, thereby reducing the space occupation requirement; at the same time, the anti-shake carrier that needs high-frequency multi-directional movement can only carry the lens and the anti-shake voice coil, so that the load is at a lower level, which can reduce the difficulty of anti-shake precision control to a certain extent, and help to improve the anti-shake effect and maintain the stability of the anti-shake effect; on the other hand, by using the anti-shake base as a mover in the focus function mechanism with a relatively low movement frequency and fewer directions, and carrying the lens, the anti-shake carrier, the anti-shake magnet and other anti-shake related components, it is possible to relatively reduce the load of the anti-shake function mechanism while maintaining the stability of the focus function effect, thereby helping to improve the anti-shake effect of the integrated anti-shake focus drive as a whole.

[0070] See also Figure 1 and Figure 2 In some embodiments, the anti-shake magnet 51 and the anti-shake coil 52 can be arranged relative to each other along the direction of the optical axis F, that is, the anti-shake coil 52 can be arranged at the bottom of the anti-shake carrier 4, and the anti-shake magnet 51 can be arranged at the inner lower part of the anti-shake base 2, so that there is no need to reserve space for installing the anti-shake coil 52 and the anti-shake magnet 51 in the translation direction of the carrier 4, thereby relatively reducing the width of the anti-shake base 2 in the translation direction of the carrier 4. On the whole, the width specification of the anti-shake focus drive can be reduced, and the demand for the size of the installation space can be reduced, which helps to expand the application scope of the anti-shake focus drive to a certain extent.

[0071] Figure 4 Shows Figure 2 A schematic diagram of the arrangement of the anti-shake magnet and the anti-shake coil of the anti-shake drive assembly; Fig. 9 Shows Figure 1 A schematic diagram of the structure of an anti-shake carrier of an anti-shake focus driver; Fig.11 Shows Figure 1 Schematic diagram of the structure of the focus base of the anti-shake focus drive.

[0072] See also Figure 1 , Figure 4 , Fig. 9 and Fig.11 In some embodiments, in order to improve the movement efficiency and accuracy of the anti-shake carrier 4 in the orthogonal plane of the optical axis F, the anti-shake driving component 5 can be set to a mode of driving the anti-shake carrier 4 to move in two vertical directions in the orthogonal plane of the optical axis F.

[0073] To this end, the anti-shake magnet 51 may include a first magnet 511 and a second magnet 512, and the anti-shake coil 52 may correspondingly include a first coil 521 and a second coil 522. The first magnet 511 is opposite to the first coil 521, and the force exerted on the first coil 521 when powered on in the magnetic field of the first magnet 511 is configured as a driving force for driving the anti-shake carrier 4 to move along a first direction X orthogonal to the optical axis F; the second magnet 512 is opposite to the second coil 522, and the force exerted on the second coil 522 when powered on in the magnetic field of the second magnet 512 is configured as a driving force for driving the anti-shake carrier 4 to move along a second direction Y orthogonal to the optical axis F, and the first direction X and the second direction Y are perpendicular.

[0074] Generally speaking, the first magnet 511 and the second magnet 512 can be set as magnets of the same specifications, and the two can be set in the same plane; the first coil 521 and the second coil 522 can also be set as coils of the same specifications, and the two can be set in the same plane; wherein, the spacing between the first magnet 511 and the first coil 521 is consistent with the spacing between the second magnet 512 and the second coil 522, so that the forces of the anti-shake magnet 51 in two orthogonal directions can be coplanar, thereby ensuring the stability of the posture of the anti-shake carrier 4.

[0075] In some embodiments, in order to improve the force balance of the anti-shake carrier 4 during translation and maintain its translation posture, the forces applied to the anti-shake carrier 4 by the anti-shake driving component 5 can be configured as two symmetrical forces, and the directions of the two forces are the same. Specifically, the forces along the first direction X are configured as two symmetrical forces about the center of the anti-shake carrier, and the forces along the second direction Y are also configured as two symmetrical forces about the center of the anti-shake carrier.

[0076] To this end, the first magnet 511 and the second magnet 512 can be set as two respectively, the first coil 521 and the second coil 522 can also be set as two, and the two first magnets 511 are symmetrically arranged about the central axis of the circular first light-transmitting window 21, and the two second magnets 512 are symmetrically arranged about the central axis of the first light-transmitting window 21; accordingly, each first magnet 511 is configured with a relatively arranged first coil 521, and each second magnet 512 is also configured with a relatively arranged second coil 522.

[0077] In some embodiments, the anti-shake base 2 can be set as a rectangular piece for easy assembly. In order to reduce the overall width of the anti-shake base 2, the four corners of the rectangular anti-shake base 2 can be used as the installation area of ​​the anti-shake magnet 51, so that there is no need to leave space in the four sides of the rectangular area to place the anti-shake magnet 51, which can reduce the width of the anti-shake base 2 to a certain extent; the size of the first light-transmitting window 21 can also be relatively increased when the specifications of the anti-shake base 2 are the same, so as to reduce the risk of blocking the light passing through the lens, so as to improve the maximum light transmittance of the camera module and help improve the shooting quality.

[0078] Figure 5 Shows Figure 1 Schematic diagram of the structure of the anti-shake base of the anti-shake focus drive.

[0079] See also Figure 4 and Figure 5 In some embodiments, anti-shake magnet installation grooves 22 may be respectively provided at the four corner areas of the inner bottom of the anti-shake base 2 for installing and fixing the anti-shake magnet 51. Specifically, first magnet installation grooves 221 may be provided at two corner areas on a diagonal line of the anti-shake base 2, and one first magnet 511 may be installed respectively; second magnet installation grooves 222 may be provided at two corner areas on another diagonal line of the anti-shake base 2, and one second magnet 512 may be installed respectively.

[0080] Generally speaking, the anti-shake base 2 can be set to a square shape, and the first light-transmitting window 21 on the anti-shake base 2 can be set at the center of the anti-shake base 2, so that the two first magnets 511 are symmetrically arranged about the central axis of the anti-shake base 2, and the two second magnets 512 are also symmetrically arranged about the central axis of the anti-shake base 2, so that it is convenient to maintain the driving effect of the force of the two groups of the first magnets 511 and the first coil 521 balanced, and it is also possible to maintain the driving effect of the force of the two groups of the second magnets 512 and the second coil 522 balanced, so as to ensure the stability of the posture of the anti-shake carrier 4. On the other hand, it is also convenient for the force between the first magnet 511 and the first coil 521 to maintain an orthogonal state with the force between the second magnet 512 and the second coil 522.

[0081] See also Figure 1 and Figure 2In some embodiments, in order to achieve stable support of the anti-shake carrier 4 and smooth movement of the anti-shake base 2, an elastic support member 53 can be connected between the anti-shake base 2 and the anti-shake carrier 4 so that the anti-shake carrier 4 can be movably mounted on the anti-shake base 2; and the elastic deformation direction of the elastic support member 53 can be set to be orthogonal to the optical axis F, so as to synchronously generate a reset force when the anti-shake carrier 4 moves in a direction perpendicular to the optical axis F, thereby prompting the anti-shake carrier 4 to reset.

[0082] Among them, the reset force is roughly opposite to the direction of the force between the anti-shake magnet 51 and the energized anti-shake coil 52, that is, they serve as resistance to each other, so that the moving speed of the anti-shake carrier 4 will not change suddenly, but maintain a relatively stable and smooth change, thereby maintaining the accuracy of the anti-shake movement, avoiding the picture jump of the image sensor, and ensuring the shooting quality.

[0083] In some embodiments, the elastic support member 53 can be configured as a rod 531, and the rod 531 can generate radial elastic deformation to generate a restoring force. The two ends of the rod 531 are respectively connected to the anti-shake carrier 4 and the anti-shake base 2, and the anti-shake carrier 4 is supported along the axial direction of the rod 531.

[0084] Generally speaking, the rods 531 can be provided in a plurality and evenly arranged between the anti-shake base 2 and the anti-shake carrier 4; for example, the number of the rods 531 can be set to four, which are respectively arranged at the four corners of the anti-shake base 2. Alternatively, the number of the rods 531 can be set to eight, and two rods 531 can be respectively arranged at each corner of the anti-shake base 2.

[0085] Typically, the material of the rod 531 can be set to a material with good elasticity and rigidity, such as a hard metal rod, so as to maintain the support and elastic reset performance of the rod.

[0086] In some embodiments, the anti-shake carrier 4 can also be slidably disposed on the anti-shake base 2 through other structures, and the elastic support member 53 only provides a reset force; for example, the anti-shake carrier 4 can be slidably embedded in the anti-shake base 2, or can also be slidably disposed on the anti-shake base 2 through a sliding assembly, a suspension assembly, a rolling support assembly, etc. In coordination, the elastic support member 53 can be a spring, a reed, etc.

[0087] Figure 7 Shows Figure 5 A schematic structural diagram of a first conductive circuit embedded in an anti-shake base of an anti-shake focus driver; Figure 8 Shows Figure 7Schematic diagram of the distribution state of the first conductive circuit in FIG.

[0088] See also Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 In some embodiments, in order to simplify the spatial arrangement of the electrical connection structure of the anti-shake coil 52 and reduce the risk of interference, the elastic support member 53 can be used as a conductive member, and the anti-shake coil 52 and the first conductive circuit 23 set on the anti-shake base 2 are electrically connected through the elastic support member 53. The first conductive circuit 23 on the anti-shake base 2 is connected to the signal connection terminal 61 set on the focusing base 1 through a flexible spring wire 24 with conductive ability, so that it is directly connected to the anti-shake coil 52 on the anti-shake carrier 4 without setting a flying wire, thereby reducing the risk of interference with the anti-shake movement process of the anti-shake carrier 4 through a simple conductive structure.

[0089] In some embodiments, the first end of the spring wire 24 can be configured as an external signal end 241 for connecting to the signal connection terminal 61 on the focusing base 1, and the end of the rod 531 connected to the anti-shake base 2 is electrically connected to the second end of the spring wire 24, and the second end of the rod 531 is electrically connected to the anti-shake coil 52, thereby avoiding the risk of interference with the anti-shake carrier 4 caused by the direct connection of the spring wire 24 to the anti-shake coil 52, simplifying the electrical connection structure of the anti-shake coil 52 to a certain extent, thereby improving the smoothness of the movement of the anti-shake carrier 4 to a certain extent.

[0090] In some embodiments, in order to further reduce the risk of the spring wire 24 penetrating deeply into the anti-shake base 2 and interfering with surrounding structures, the first conductive circuit 23 can be pre-buried in the anti-shake base 2, and an inner joint 231 and an outer joint 232 are respectively provided on the inner and outer sides of the anti-shake base 2 for connecting the rod 531 and the spring wire 24.

[0091] Among them, the inner joint 231 matches the fixed position of the rod 531, so as to electrically connect the end of the rod 531 located on the anti-shake base 2; the outer joint 232 can be set on the anti-shake base 2 away from the moving range of the anti-shake carrier 4, so that when the outer joint 232 is connected to the spring wire 24, the spring wire 24 does not need to go deep into the anti-shake base and can maintain a certain distance from the anti-shake carrier, reducing the risk of interference.

[0092] At the same time, by pre-embedding the first conductive line 23 in the anti-shake base 2, the insulation performance can be improved, the risk of line short circuit can be reduced, the reliability of electrical signal transmission can be improved, and the stability of the anti-shake effect can be ensured.

[0093] Generally speaking, a third pad 242 may be provided at the second end of the spring wire 24 to connect to the signal connection terminal 61 .

[0094] In some embodiments, in order to improve the reliability of fixation and electrical connection between the rod 531 and the inner joint 231, the inner joint 231 can be set as a first soldering pad 231a with a central opening, and the end of the rod 531 can be embedded in the first soldering pad 231a and fixed by welding.

[0095] In some embodiments, a fixing groove 231b may be further opened at the bottom of the anti-shake base 2 to expose the first welding pad 231a, so as to facilitate the fixation of the rod 531 and to leave a swing space for the rod 531 to a certain extent, thereby reducing the influence of the anti-shake base 2 on the anti-shake deformation of the rod 531.

[0096] In some embodiments, in order to improve the convenience and stability of the electrical connection between the rod 531 and the anti-shake coil 52, the anti-shake driving assembly 5 may further include a connecting spring 54, which is disposed on the anti-shake carrier 4 and serves as an electrical connection medium between the anti-shake coil 52 and the rod 531. The connecting spring 54 is an elastically deformable member, which is electrically connected between the anti-shake coil 52 and the rod 531, so that the deformation stress of the rod 531 can be absorbed by the deformation of the connecting spring 54, so as to reduce the risk of destructive deformation or even fracture of the rod 531.

[0097] Figure 6 Shows Figure 1 Schematic diagram of the structure of the connecting spring in the anti-shake drive assembly. Figure 1 , Figure 6 and Figure 7 In some embodiments, in order to improve the performance of the connecting spring 54 in absorbing the deformation stress of the rod 531, an elastic connecting arm 541 can be provided on the connecting spring 54, extending toward the outside of the connecting spring 54 to obtain a larger deformation amplitude, thereby obtaining a greater adaptability through the elastic deformation of the elastic connecting arm 541, and having the ability to absorb a larger range of deformation stress, thereby improving the stability of the anti-shake effect.

[0098] Generally speaking, the elastic connecting arm 541 can be configured to be a continuous multi-section zigzag shape, thereby improving the deformation capability.

[0099] In some embodiments, in order to reduce the influence of interference factors such as vibration and swing of the elastic connecting arm 541 on the anti-shake effect, the elastic connecting arm 541 can be set to two branches, which are respectively connected to the two sides of the rod 531, so that the connecting spring 54, the two elastic connecting arms 541 and the rod 531 form an annular structure, thereby limiting the vibration and swing amplitude of the elastic connecting arm 51; on the other hand, the structural stability can be further enhanced through the synchronous deformation of the two elastic connecting arms 541, thereby ensuring the support stability of the rod 531, that is, ensuring the stability of the support height of the anti-shake carrier 4.

[0100] In some embodiments, in order to improve the connection convenience and fixing stability between the rod 531 and the elastic connecting arm 541, a second welding pad 542 with a central opening can be connected between the two elastic connecting arms 541, and the rod 531 can be embedded in the second welding pad 542 and fixed by welding.

[0101] In some embodiments, the connecting spring piece 54 may be riveted onto the anti-shake carrier 4 , and the fixing strength of the connecting spring piece 54 may be improved by glue dispensing.

[0102] A through hole 543 may also be provided on the connecting spring 54 to accommodate more adhesive material and enhance the bonding stability between the connecting spring 54 and the anti-shake carrier 4 .

[0103] In some embodiments, in order to facilitate installation, the connecting spring 54 or the elastic connecting arm 541 can be extended out of the side edge of the anti-shake carrier 4, so that the rod 531 is arranged on the axial outside of the anti-shake carrier 4, which can reduce the difficulty of installing the rod 531 and can also reduce the risk of collision between the rod 531 and the anti-shake carrier 4 to a certain extent.

[0104] In some embodiments, in order to prevent the installation of the rod 531 from increasing the width of the anti-shake base 2, an avoidance groove 42 along the optical axis F can be opened on the circumferential side of the anti-shake carrier 4, and the rod 531 can be arranged in the avoidance groove 42, and a certain gap is reserved between the rod 531 and the side wall of the avoidance groove 42 as an avoidance space, leaving deformation space for the rod 531.

[0105] In some embodiments, for ease of installation, the connecting spring 54 can be installed on an end surface of the anti-shake carrier 4 away from the anti-shake coil 52, that is, configured to be installed on an end surface of the lens, thereby providing a larger installation operation space.

[0106] Generally speaking, in order to prevent the connecting spring 54 and its riveting and glue-dispensing structure from protruding from the end face of the anti-shake carrier 4 and causing interference risk, a sunken groove 43 can be opened on the end face of the anti-shake carrier 4 to accommodate and fix the connecting spring 54.

[0107] See also Figure 1 , Figure 3 , Figure 6 and Figure 7 In some embodiments, in order to facilitate the electrical connection between the connecting spring 54 and the anti-shake coil 52, a second conductive circuit 44 may be pre-buried in the anti-shake carrier 4, and the two ends of the second conductive circuit 44 are respectively connected to the connecting spring 54 and the anti-shake coil 52, thereby further simplifying the electrical connection structure of the anti-shake coil 52, improving the simplicity of the electrical connection in the anti-shake function mechanism, and reducing the risk of interference.

[0108] Generally speaking, a connection clamp 544 may be provided on the connection spring 54 , and the end of the second conductive line 44 may be clamped in the clamp 544 and welded to improve the stability of the electrical connection.

[0109] Fig.10 Shows Figure 1 A structural schematic diagram of the assembly state of the guide member of the anti-shake focus actuator; Fig.11 Shows Figure 1 Schematic diagram of the structure of the focus base of the anti-shake focus drive.

[0110] See also Figure 1 , Figure 3 , Fig.10 and Fig.11 In some embodiments, a cavity with a certain depth may be provided in the focus base 1 to accommodate and install the anti-shake base 2 and cooperate to realize the reciprocating movement of the anti-shake base 2 in the direction of the optical axis F. Accordingly, the focus driving assembly 3 may be connected between the side wall 17 of the focus base 1 and the side wall of the anti-shake base 2 to drive the anti-shake base 2 to move along the optical axis F.

[0111] Specifically, the focus drive assembly 3 may include a third magnet 31 and a third coil 32 that are relatively arranged. The third magnet 31 may be arranged on the anti-shake base 2, and the third coil 32 may be arranged on the focus base 1. The third coil is connected to the drive circuit 6 to be powered on to obtain a drive signal, wherein the magnetic field force of the third magnet 31 applied to the third coil 32 in the powered-on state is the driving force for the movement of the anti-shake base 2, and is configured to be a force that drives the anti-shake base 2 to move along the direction of the optical axis F relative to the focus base 1.

[0112] In some embodiments, in order to maintain the stability of the moving posture of the anti-shake base 2 in the direction along the optical axis F, a guide member 12 can be connected between the anti-shake base 2 and the focusing base 1 to limit the swing amplitude of the anti-shake base 2 in the non-optical axis direction.

[0113] See also Figure 2 , Figure 3 , Figure 7 , Fig.10 and Fig.11 In some embodiments, the guide member 12 may include a plurality of balls 121 abutting between the side wall 17 of the anti-shake base 2 and the focusing base 1; generally speaking, the plurality of balls 121 may be rolled and clamped between the side wall 17 of the anti-shake base 2 and the focusing base 1, so as to keep the anti-shake base 2 moving stably along the direction of the optical axis F based on the side wall 17 of the focusing base 1.

[0114] It is worth noting that a steel sheet 16 or a magnet may be provided on the side wall 17 of the focusing base 1 , opposite to the third magnet 31 , and maintaining mutual attraction, so as to tighten the anti-shake base 2 on the side wall 17 of the focusing base 1 and press the multiple balls 121 .

[0115] Typically, the plurality of balls 121 may be arranged in three numbers, with non-collinear intervals arranged between the side wall of the anti-shake base 2 and the side wall 17 of the focusing base 1, thereby forming three non-collinear fulcrums, ensuring that the distance between the side surface of the anti-shake base 2 and the inner side surface of the side wall 17 of the focusing base 1 is stable, thereby ensuring the stability of the focusing movement posture of the anti-shake base 2.

[0116] In some embodiments, in order to prevent the ball 121 from losing its position during rolling, a first guide groove 25 along the optical axis F can be opened on the circumferential side of the anti-shake base 2, and the ball 121 can be rotatably arranged in the first guide groove 25, so that the ball 121 can only roll along the direction of the optical axis F.

[0117] Furthermore, a second guide groove 13 along the optical axis F may also be provided on the inner side surface of the side wall 17 of the focusing base 1 to accommodate the ball 121 , so that the ball 121 can only roll along the direction of the optical axis F.

[0118] In some embodiments, a first guide groove 25 may be further provided on the anti-shake base 2, and a second guide groove 13 opposite to the first guide groove 25 may be provided on the focusing base 1. The ball 121 may be rollably abutted between the first guide groove 25 and the second guide groove 13, thereby guiding the ball 121 along the optical axis F and synchronously limiting the movement range of the anti-shake base 2 in a direction orthogonal to the optical axis F to ensure focusing stability.

[0119] In some embodiments, the guide member 12 may also adopt a guiding structure in the form of a guide rod; for example, a guide rod may be arranged on the focusing base 1 along the direction of the optical axis F, a guide hole may be opened on the anti-shake base 2, and the guide rod may be passed through the guide hole, thereby ensuring the stability of the focusing movement direction of the anti-shake base 2.

[0120] In some embodiments, an installation window 14 may be opened on the side wall 17 of the focus base 1 to accommodate the installation of the third coil 32, thereby reducing the thickness of the side wall 17 of the focus base 1 to a certain extent, thereby reducing the overall width of the anti-shake focus driver as a whole.

[0121] In some embodiments, in order to simplify the structure and reduce the weight of the focusing base 1 , the side wall 17 of the focusing base 1 may be provided as only one side, which is used for guiding in cooperation with the anti-shake carrier 4 .

[0122] Generally speaking, limiting side plates 18 can be respectively provided on the other three sides of the focusing base 1 to limit the position of the anti-shake base 2 and to limit the external structure from extending into the range of the focusing base 1 to ensure the reliability of focusing and anti-shake operations.

[0123] In some embodiments, the driving circuit 6 is used to receive an external driving signal, and load the corresponding driving signal to the anti-shake coil 52 and the third coil 32 respectively, so as to achieve anti-shake and focusing actions.

[0124] Specifically, the driving circuit 6 can be configured as a circuit structure for transmitting a driving signal to the anti-shake coil 52 and the third coil 32, and is provided with a signal connection terminal 61, which is electrically connected to the external signal terminal 241 of the first end of the spring wire 24 and the third coil 32 respectively; in the assembled state, the signal connection terminal 61 is connected to an external control unit to obtain a driving signal.

[0125] Generally speaking, the signal connection terminal 61 can be installed on the focusing base 1 as a stable connection end connecting the spring wire 24 and the third coil 32, and can also be used as a terminal for connecting to an external control system and receiving a control signal.

[0126] Alternatively, the driving circuit 6 can also be configured as a complete control system with an on-site MCU controller, which is directly set in the anti-shake and focus driver and directly connected to the external signal end 241 of the spring wire 24 and the third coil 32 respectively to implement the control of anti-shake and focus actions.

[0127] See also Figure 1 , Figure 2 and Figure 7 In some embodiments, in order to accurately obtain the position of the anti-shake carrier, a first magnetic field sensor can be set on the anti-shake carrier 2 and connected to an external control unit or an on-site MCU controller to detect the magnetic field signal of the first magnet in real time as a detection signal for feedback closed-loop control of the anti-shake action, which helps to improve the anti-shake shift accuracy.

[0128] Similarly, in order to accurately obtain the position of the anti-shake base, a second magnetic field sensor 33 can be set on the focusing base 1 and connected to an external control unit or an on-site MCU controller to detect the magnetic field signal of the third magnet 31 in real time as a detection signal for feedback closed-loop control of the focusing action, which helps to improve the focus shift accuracy.

[0129] See also Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 In some embodiments, in order to improve the accuracy of magnetic field detection, a magnetic focusing sheet 26 can be provided on the anti-shake base 2 and placed on one side of the anti-shake magnet 51 to improve the uniformity of the magnetic field distribution of the anti-shake magnet 51 and improve the reliability of magnetic field strength detection, thereby improving the anti-shake accuracy control.

[0130] In some embodiments, the anti-shake coil 52 may be integrated on a printed circuit board 523 to form a printed circuit board coil.

[0131] See also Figure 5 , Fig. 9 , Fig.10 , Fig.12 and Fig.13 In some embodiments, in order to improve the position stability and impact resistance of the anti-shake carrier 4 and the components installed thereon, a cover plate 45 can be provided on the anti-shake carrier 4 to close the cavity provided in the anti-shake carrier 4 and to constrain and protect the components installed on the anti-shake carrier 4 therein.

[0132] Generally speaking, the cover sheet 45 is provided with a hook 452 , and the anti-shake carrier 4 is provided with a slot 47 , so that the cover sheet 45 can be installed by snapping the hook 452 into the slot 47 .

[0133] In some embodiments, a positioning groove 46 may be provided on the anti-shake carrier 4 , and a positioning column 451 is provided on the cover plate 45 . The positioning column 451 may be embedded in the positioning groove 46 to ensure the fixed state and stable position of the cover plate 45 .

[0134] In some embodiments, a housing 15 may be further configured on the focus base 1 to protect the anti-shake focus driver as a whole.

[0135] Generally speaking, the housing 15 can be positioned and installed by relying on the side wall 17 on the focusing base 1 and the limiting side plate 18 respectively, so as to prevent the housing 15 from affecting the focusing and anti-shake operations.

[0136] On the other hand, an embodiment of the present application provides a camera module, which adopts the above-mentioned anti-shake focus driver and also includes a lens and an image sensor; the lens can be installed on the anti-shake carrier 4, and the image sensor is arranged on the light output side of the lens, and the light passing through the lens can be projected onto the image sensor to achieve imaging; the focusing base 1 can be installed on the internal supporting structure of the camera module, and the lens can be installed on the anti-shake carrier 4.

[0137] When implementing the focusing operation, the external control device can load electrical signals to the anti-shake coil and the focus drive component through the driving circuit respectively, so as to control the anti-shake carrier to carry the lens and move it in a direction orthogonal to the optical axis of the lens to achieve anti-shake, and can also control the anti-shake base to carry the lens and move back and forth in the direction of the optical axis to achieve focusing.
