TECHNICAL FIELD

[0002] The present application relates to the technical field of shooting devices, and in particular to a motor, a camera module and an electronic device. BACKGROUND

[0003] With the continuous development of portable electronic devices such as mobile phones, users have higher and higher requirements for the shooting performance of portable electronic devices. Electronic devices with optical image stabilization and focusing functions are increasingly favored by users. A traditional camera module includes an anti-shake carrier, a focusing carrier, a focusing driving mechanism and an anti-shake driving mechanism. The focusing carrier is located on the inner side of the anti-shake carrier and movably connected to the anti-shake carrier. The focusing driving mechanism is used to drive the focusing carrier to move, and the anti-shake driving mechanism is used to drive the anti-shake carrier and the focusing carrier to move. The load of the anti-shake driving mechanism is large, and the anti-shake driving mechanism needs a large size to generate sufficient driving force, so the size of the traditional camera module is large. In addition, due to the unreasonable arrangement of the focusing driving mechanism and the anti-shake driving mechanism, the electrical connection mode of the focusing driving mechanism and the anti-shake driving mechanism and the structure of the motor are complex. SUMMARY

[0004] The present application provides a motor, a camera module and an electronic device which have a small size and a simple structure.

[0005] In a first aspect, the present application provides a motor. The motor comprises a base, a focusing carrier, an anti-shake carrier, a focusing magnetic piece, a focusing coil, a first anti-shake coil, a second anti-shake coil, a first anti-shake magnetic piece, a second anti-shake magnetic piece, and an electrical connecting piece. The focusing carrier is movably connected to the base, and the anti-shake carrier is located on the inner side of the focusing carrier and movably connected to the focusing carrier. The focusing magnetic piece is fixedly connected to the base, and the focusing coil is fixedly connected to the focusing carrier and faces the focusing magnetic piece, and is used to drive the focusing carrier and the anti-shake carrier to move relative to the base along a first direction. The first anti-shake coil is fixedly connected to the focusing carrier, the first anti-shake magnetic piece is fixedly connected to the anti-shake carrier, the first anti-shake coil is located on one side of the first anti-shake magnetic piece, the first anti-shake coil faces the first anti-shake magnetic piece, and is used to drive the anti-shake carrier to move relative to the focusing carrier along a second direction, the second direction being different from the first direction. The second anti-shake coil is fixedly connected to the focusing carrier, the second anti-shake magnetic piece is fixedly connected to the anti-shake carrier, the second anti-shake coil is located on one side of the second anti-shake magnetic piece, the second anti-shake coil faces the second anti-shake magnetic piece, and is used to drive the anti-shake carrier to move relative to the focusing carrier along a third direction, the third direction being different from the first direction and the second direction. The electrical connecting piece comprises a first fixed part, a deformation part, and a second fixed part. The first fixed part is fixedly connected to the base, the second fixed part is fixedly connected to the focusing carrier, and the electrical connecting piece is electrically connected to the focusing coil, the first anti-shake coil, and the second anti-shake coil. When the focusing carrier moves relative to the base along the first direction, the deformation part deforms.

[0006] It can be understood that the anti-shake carrier is located on the inner side of the focusing carrier, that is, the motor is a motor structure of "focusing anti-shake", the first anti-shake coil and the first anti-shake magnetic piece can cooperate, the second anti-shake coil and the second anti-shake magnetic piece can cooperate, and are used to drive the anti-shake carrier to complete optical anti-shake, that is, the load of the first anti-shake coil, the second anti-shake coil, the second anti-shake coil, and the second anti-shake magnetic piece in the embodiment is small. Therefore, the driving force generated by the first anti-shake coil, the second anti-shake coil, the second anti-shake coil, and the second anti-shake magnetic piece is small, the size of the first anti-shake coil, the second anti-shake coil, the second anti-shake coil, and the second anti-shake magnetic piece is small, and the size of the motor is small, which is beneficial to realize the miniaturization of the motor.

[0007] It can be understood that the first anti-shake coil is located on one side of the first anti-shake magnetic piece, the second anti-shake coil is located on one side of the second anti-shake magnetic piece, and the first anti-shake coil, the second anti-shake coil, the first anti-shake magnetic piece, and the second anti-shake magnetic piece are reasonably arranged, the structure of the motor is simpler, and the assembly process of the motor can be simplified. In addition, the risk of short circuit between the first anti-shake coil, the second anti-shake coil, the first anti-shake magnetic piece, and the second anti-shake magnetic piece and other structural pieces can be reduced.

[0008] It can be understood that the structure of the electrical connection between the focusing coil, the first anti-shake coil and the second anti-shake coil and the base is relatively simple, and the structure of the motor is relatively simple. In addition, the deformation part is connected between the first fixed part and the second fixed part, and the deformation part can be deformed during the movement of the second fixed part along the first direction Z with the focusing carrier relative to the base, so as to ensure the electrical connection between the focusing coil, the first anti-shake coil and the second anti-shake coil and the base, and can not affect the movement of the focusing carrier.

[0009] In a possible implementation, the first anti-shake coil and the first anti-shake magnetic piece are arranged along the first direction.

[0010] It can be understood that by arranging the first anti-shake coil and the first anti-shake magnetic piece along the first direction, the size of the motor in the X-Y direction can be reduced.

[0011] In a possible implementation, the second anti-shake coil and the second anti-shake magnetic piece are arranged along the first direction.

[0012] It can be understood that by arranging the second anti-shake coil and the second anti-shake magnetic piece along the first direction, the size of the motor in the X-Y direction can be reduced.

[0013] In a possible implementation, the first anti-shake magnetic piece is a Halbach magnet array.

[0014] It can be understood that the first anti-shake magnetic piece is a Halbach magnet array, and the first anti-shake coil and the first anti-shake magnetic piece cooperate to generate a relatively large anti-shake driving force along the second direction, which can drive the anti-shake carrier to complete optical anti-shake.

[0015] In a possible implementation, the second anti-shake magnetic piece is a Halbach magnet array.

[0016] It can be understood that the second anti-shake magnetic piece is a Halbach magnet array, and the second anti-shake coil and the second anti-shake magnetic piece cooperate to generate a relatively large anti-shake driving force along the third direction, which can drive the anti-shake carrier to complete optical anti-shake.

[0017] In a possible implementation, the focusing coil is located on one side of the focusing magnetic piece, and the winding plane of the focusing coil is parallel to the first direction.

[0018] It can be understood that during focusing, the focusing coil can move along the first direction with the focusing carrier, in other words, during focusing, the focusing magnetic piece and the focusing coil of the present embodiment are designed as moving coils. In this way, the focusing magnetic piece can avoid magnetic interference with the first anti-shake magnetic piece, the second anti-shake magnetic piece or other magnetic structural pieces. In addition, the winding plane of the focusing coil can be parallel to the first direction, which is beneficial to reduce the size of the motor in the X-Y direction.

[0019] In a possible implementation, the deformation portion is provided with a through hole.

[0020] It can be understood that, compared with the electrical connector of the deformation portion without the through hole, the K value of the electrical connector of the deformation portion with the through hole is reduced, where the K value is the elastic coefficient. Then, in the case that the same deformation amount of the deformation portion is generated, the elastic force of the electrical connector of the embodiment is smaller. In this way, in the process that the second fixed portion of the electrical connector moves along the first direction Z with the focusing carrier and the anti-shake carrier, the elastic force of the electrical connector is smaller, the influence of the elastic force of the electrical connector on the focusing process is smaller, and thus the stability of the movement of the motor is improved. In addition, the deformation of the electrical connector is caused by the movement of the focusing carrier and the anti-shake carrier along the first direction Z, the deformation of the electrical connector is smaller, the driving force required by the deformation is smaller, and the driving force required to be provided by the focusing magnetic member and the focusing coil is smaller, which is beneficial to reducing the volume of the focusing magnetic member and the focusing coil.

[0021] In a possible implementation, the through hole is a strip-shaped hole, and the through hole extends along the length extension direction of the deformation portion.

[0022] It can be understood that, compared with the scheme in which the deformation portion is not provided with the through hole, the through hole of the deformation portion in the embodiment is arranged in a bifurcated manner, the width of the deformation portion along the second direction or the third direction is smaller, the K value of the electrical connector of the embodiment can be reduced, and the elastic force of the electrical connector can be reduced.

[0023] In a possible implementation, in the thickness direction of the deformation portion, the deformation portion includes a plurality of deformation sub-portions, the first end portion of each deformation sub-portion is fixedly connected with the first fixed portion, the second end portion of each deformation sub-portion is fixedly connected with the second fixed portion, and the adjacent two deformation sub-portions are arranged in a spaced manner to form a hollow region.

[0024] It can be understood that, compared with the scheme in which the deformation portion is not arranged in a layered manner, the deformation portion arranged in a layered manner in the embodiment has a smaller thickness along the first direction, and the K value of the electrical connector of the embodiment can be reduced.

[0025] It can be understood that, compared with the electrical connector of the deformation portion without the layered arrangement, the K value of the electrical connector of the deformation portion arranged in a layered manner in the embodiment is reduced. In this way, in the process that the second fixed portion of the electrical connector moves along the first direction with the focusing carrier and the anti-shake carrier, the elastic force of the electrical connector is smaller, the influence of the elastic force of the electrical connector on the focusing process is smaller, and thus the stability of the movement of the motor is improved. In addition, the deformation of the electrical connector is caused by the movement of the focusing carrier and the anti-shake carrier along the first direction, the deformation of the electrical connector is smaller, the driving force required by the deformation is smaller, and the driving force required to be provided by the focusing magnetic member and the focusing coil is smaller, which is beneficial to reducing the volume of the focusing magnetic member and the focusing coil.

[0026] In a possible implementation, at least part of the deformation portion is in a spiral shape, a polyline shape, or a curved shape.

[0027] It can be understood that the deformation portion in the embodiment can be elongated. Compared with the case where the deformation portion is not elongated, the K value of the electrical connector in the embodiment can be reduced. In this way, during movement of the second fixing portion of the electrical connector along the first direction with the focusing carrier and the anti-shake carrier, the elastic force of the electrical connector is smaller, the influence of the elastic force of the electrical connector on the focusing process is smaller, and thus the stability of movement of the motor is improved. In addition, the deformation of the electrical connector is caused by movement of the focusing carrier and the anti-shake carrier along the first direction, the deformation of the electrical connector is smaller, the driving force required for the deformation is smaller, and the driving force required to be provided by the focusing magnetic member and the focusing coil is smaller, which is beneficial to reducing the volume of the focusing magnetic member and the focusing coil.

[0028] In a possible implementation, the focusing carrier includes a bottom plate, a first side plate, and a second side plate, the first side plate and the second side plate are located on the same side of the bottom plate and are fixedly connected to the bottom plate, the focusing coil is fixedly connected to the first side plate, the first anti-shake coil and the second anti-shake coil are fixedly connected to the bottom plate, and the second fixing portion includes a first part and a second part, the first part is fixedly connected to the second side plate, and the second part is located on the side of the bottom plate close to the base and is fixedly connected to the bottom plate.

[0029] It can be understood that the structure in which the focusing coil, the first anti-shake coil, and the second anti-shake coil are electrically connected to the base is relatively simple, and the structure of the motor is relatively simple.

[0030] In a possible implementation, the motor includes a driving chip, the driving chip is located on the side of the first part close to the focusing carrier, the driving chip is fixedly connected to and electrically connected to the first part, the focusing coil is electrically connected to the driving chip through the first part of the second fixing portion of the electrical connector, and the first anti-shake coil and the second anti-shake coil are electrically connected to the driving chip through the second part of the second fixing portion of the electrical connector.

[0031] It can be understood that, compared with the case where the driving chip is located on the side of the electrical connector away from the focusing carrier, the first part of the second fixing portion of the electrical connector in the embodiment can not need to be bent by a large angle in the direction close to the second part.

[0032] It can be understood that the driving chip can control the focusing process of the motor by controlling the current situation (for example, whether to pass current or the size of the current when passing current, etc.) of the focusing coil through the first part of the second fixed part of the electrical connector. The driving chip can control the optical anti-shake process of the motor by controlling the current situation (for example, whether to pass current or the size of the current when passing current, etc.) of the first anti-shake coil and the second anti-shake coil through the second part of the second fixed part of the electrical connector.

[0033] In a possible implementation, the motor further includes a wire, the wire is embedded in the focusing carrier, the wire and the first part of the second fixed part of the electrical connector, the focusing coil, and the driving chip form a current loop, the wire and the second part of the second fixed part of the electrical connector, the first anti-shake coil, and the driving chip form a current loop, and the wire and the second part of the second fixed part of the electrical connector, the second anti-shake coil, and the driving chip form a current loop.

[0034] It can be understood that the driving chip can control the focusing process of the motor by controlling the current situation (for example, whether to pass current or the size of the current when passing current, etc.) of the focusing coil through the wire and the first part of the second fixed part of the electrical connector. The driving chip can control the optical anti-shake process of the motor by controlling the current situation (for example, whether to pass current or the size of the current when passing current, etc.) of the first anti-shake coil and the second anti-shake coil through the wire and the second part of the second fixed part of the electrical connector.

[0035] In a possible implementation, the second part of the second fixed part is provided with a pin end; the wire includes a bent part, the bent part is arranged along a first direction with the pin end and is fixedly connected with the pin end.

[0036] It can be understood that the bent part of the wire makes the connection process between the wire and the electrical connector simpler.

[0037] In a possible implementation, the motor includes a first guide, and the focusing carrier is movably connected to the base through the first guide.

[0038] It can be understood that the first guide can reduce the frictional resistance when the focusing carrier and the base move relative to each other, reduce the power required to be provided by the focusing magnetic member and the focusing coil, and thus reduce the size of the focusing magnetic member and the focusing coil.

[0039] In a possible implementation, the motor includes a focusing magnetic attraction member, the focusing magnetic attraction member is fixed to the focusing carrier and faces the focusing magnetic member, and the magnetic force between the focusing magnetic attraction member and the focusing magnetic member keeps the base, the first guide, and the focusing carrier in contact.

[0040] It can be understood that the magnetic force between the focusing magnetic attraction member and the focusing magnetic member makes the base, the first guide member and the focusing carrier keep in contact. During the focusing of the motor, the focusing carrier is not easy to be overturned or the like due to movement.

[0041] In a possible implementation, the focusing magnetic attraction member and the focusing carrier are in an integrated structure.

[0042] It can be understood that the focusing magnetic attraction member and the focusing carrier are in an integrated structure, so that the assembly tolerance of the focusing magnetic attraction member is small, thereby reducing the fluctuation of the magnetic force between the focusing magnetic attraction member and the focusing magnetic member, and improving the movement stability of the motor. Compared with other focusing magnetic attraction scheme structures, the focusing magnetic attraction scheme structure of the embodiment is simpler.

[0043] In a possible implementation, the base is provided with a first groove, the focusing carrier is provided with a second groove, the second groove is oppositely arranged with the first groove, and at least part of the first guide member is located in the first groove and at least part of the first guide member is located in the second groove.

[0044] It can be understood that the first groove and the second groove can limit the first guide member, preventing the first guide member from being separated from between the base and the focusing carrier.

[0045] In a possible implementation, the motor includes a second guide member, and the anti-shake carrier is movably connected to the focusing carrier through the second guide member.

[0046] It can be understood that the second guide member can reduce the frictional resistance when the focusing carrier and the anti-shake carrier relatively move, reduce the power required to be provided by the first anti-shake coil and the first anti-shake magnetic member in cooperation, and reduce the power required to be provided by the second anti-shake coil and the second anti-shake magnetic member in cooperation, thereby reducing the sizes of the first anti-shake coil, the first anti-shake magnetic member, the second anti-shake coil and the second anti-shake magnetic member.

[0047] In a possible implementation, the focusing carrier is provided with a third groove, the anti-shake carrier is provided with a fourth groove, the fourth groove is oppositely arranged with the third groove, and at least part of the second guide member is located in the third groove and at least part of the second guide member is located in the fourth groove.

[0048] It can be understood that the third groove and the fourth groove can limit the second guide member, preventing the second guide member from being separated from between the focusing carrier and the anti-shake carrier.

[0049] In a possible implementation, the second guide member is a single ball or a group of balls.

[0050] It can be understood that the movable connection of the focus carrier and the anti-shake carrier through the second guide piece can reduce the frictional resistance between the second guide piece and the anti-shake carrier while ensuring sufficient supporting force, can reduce the requirement for the size of the driving force during the movement of the anti-shake carrier, that is, is conducive to reducing the size of the first anti-shake coil and / or the first anti-shake magnetic piece, the second anti-shake coil and / or the second anti-shake magnetic piece, and is conducive to realizing the miniaturization of the motor. Illustratively, compared with the diameter of the traditional large ball, the diameter of each ball in the second guide piece of the embodiment is smaller, which is also conducive to shortening the interval between the anti-shake carrier and the base, and is conducive to realizing the thinness of the motor. In addition, the second guide piece can provide multi-point support for the anti-shake carrier, which is conducive to dispersing stress and preventing the balls in the second guide piece from being deformed due to excessive concentration of force in a single direction, and can improve the reliability of the second guide piece in supporting the anti-shake carrier and other structural pieces.

[0051] In a possible implementation manner, the motor comprises an anti-shake magnetic attraction piece, the anti-shake magnetic attraction piece is fixed to the focus carrier and is arranged to face the first anti-shake magnetic piece and the second anti-shake magnetic piece, and the magnetic force between the anti-shake magnetic attraction piece and the first anti-shake magnetic piece and the second anti-shake magnetic piece causes the anti-shake carrier, the second guide piece and the focus carrier to remain in contact.

[0052] It can be understood that the magnetic force between the first anti-shake magnetic piece and the anti-shake magnetic attraction piece and the magnetic force between the second anti-shake magnetic piece and the anti-shake magnetic attraction piece enable the anti-shake carrier to be subjected to an anti-shake magnetic force, so that the anti-shake carrier, the second guide piece and the focus carrier remain in contact, ensuring the stability of the connection between the anti-shake carrier, the second guide piece and the focus carrier, and avoiding the anti-shake carrier from being detached from the focus carrier and the like. In addition, compared with the structures of other anti-shake magnetic attraction schemes, the structure of the anti-shake magnetic attraction scheme of the embodiment is simpler.

[0053] In a possible implementation manner, the motor further comprises a spring piece, one end of the spring piece is fixedly connected to the focus carrier, and the other end of the spring piece is fixedly connected to the anti-shake carrier.

[0054] It can be understood that, since the spring piece is connected between the anti-shake carrier and the focus carrier, the movement of the anti-shake carrier causes the spring piece to elastically deform and have an elastic force, so that the anti-shake carrier is reset and can return to a position with a displacement dx. The spring piece can also provide a torsional resistance to the anti-shake carrier to hinder the rotation of the anti-shake carrier. In addition, in the embodiment, the first anti-shake coil is located on one side of the first anti-shake magnetic piece, and the second anti-shake coil is located on one side of the second anti-shake magnetic piece, which can reduce the risk of short circuit of the first anti-shake coil, the second anti-shake coil and the spring piece and the like, and improve the reliability of the motor.

[0055] In a second aspect, the present application provides a camera module. The camera module comprises a lens and the motor described above, and the lens is fixed to the anti-shake carrier.

[0056] It can be understood that the camera module has a small size and a simple structure.

[0057] In a third aspect, the present application provides an electronic device. The electronic device comprises a housing and the camera module described above, and the camera module is arranged in the housing. It can be understood that the electronic device can have a small size and a simple structure. BRIEF DESCRIPTION OF DRAWINGS

[0100] FIG. 2 is a partial cross-sectional view of the electronic device 1000 shown in FIG. 1, in an embodiment at line A-A.

[0101] As shown in FIGS. 1 and 2, in some embodiments, the electronic device 1000 can include a camera module 100, a housing 200, and a screen 300. The camera module 100 can be a rear camera module 100 or a front camera module 100. It can be understood that FIGS. 1 and 2 and the relevant drawings below only schematically show 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 FIGS. 1 and 2 and the relevant drawings below. In addition, when the electronic device 1000 is some other form of device, the electronic device 1000 can also not include the screen 300.

[0102] As shown in FIGS. 1 and 2, in some embodiments, the screen 300 is mounted to the housing 200 and cooperates with the housing 200 to enclose an interior of the electronic device 1000. The interior of the electronic device 1000 can be used to place components of the electronic device 1000, such as a battery, a receiver, or a microphone, etc. The screen 300 can be a flat screen or a curved screen.

[0103] For example, the camera module 100 can be located in the interior of the electronic device 1000. The housing 200 has a light-transmitting portion 201. The shape of the light-transmitting portion 201 is not limited to the circular shape shown in FIG. 1, but can also be an elliptical shape or an irregular shape. Light outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting portion 201. The camera module 100 can collect the light entering the interior of the electronic device 1000. The light-transmitting portion 201 can be a light-transmitting hole or a transparent portion in the housing 200. The specific structure of the light-transmitting portion 201 is not limited in particular.

[0104] FIG. 3 is a partial structure exploded view of the camera module 100 shown in FIG. 1, in an embodiment.

It can be understood that FIG. 2 and FIG. 3 only schematically show some components included in the camera module 100, and the actual shape, actual size, actual position and actual structure of these components are not limited by FIG. 2 and FIG. 3 and the following drawings. The camera module 100 can also include more or less structures. For example, the camera module 100 can also include a variable aperture (not shown in the drawings).

[0106] The lens 2 can be mounted on the motor 1, for example. The motor 1 can also control the lens 2 to move along the first direction Z to realize auto focus (AF), for example. In other words, the camera module 100 of the present application can control the lens 2 to move along the first direction Z by the motor 1 to realize auto focus of the camera module 100, and improve the imaging quality of the camera module 100.

[0107] In addition, the motor 1 can control the lens 2 to move along a plane (i.e. X-Y plane) perpendicular to the first direction Z to realize optical image stabilization (OIS). In this way, when the camera module 100 collects ambient light, if the electronic device 1000 produces a shaking in the X-Y plane due to external force, the motor 1 can control the lens 2 to move in the X-Y plane to offset the shaking stroke of the lens 2 in the X-Y plane, so as to avoid reducing the position offset of the lens 2 due to shaking. In other words, the camera module 100 of the present application can control the lens 2 to move in the X-Y plane by the motor 1 to realize optical image stabilization of the camera module 100, and improve the imaging quality of the camera module 100.

[0108] The length direction of the motor 1 can be the X axis, for example. The width direction of the motor 1 can be the Y axis. The thickness direction of the motor 1 can be the Z axis. In other embodiments, the coordinate system of the motor 1 can be flexibly set according to specific actual needs.

[0109] The motor 1 can control the lens 2 to move along the X axis direction, the Y axis direction or the Z axis direction, for example.

[0132] It can be understood that although the focusing carrier 13 is divided into five parts for introduction, it does not affect that the focusing carrier 13 can be an integrally formed structure. In addition, in other embodiments, the focusing carrier 13 can also be formed by different independent structural members through an assembly process. For example, the first side plate 132 and the second side plate 133 of the focusing carrier 13 can be fixed to the bottom plate 131 of the focusing carrier 13 by welding, bonding, or the like.

[0135] FIG. 9 is a partial structural schematic diagram II of the motor 1 shown in FIG. 3 in an embodiment.

[0136] As shown in FIG. 9, the focusing coil 142 can be fixedly connected with the focusing carrier 13. Exemplarily, the focusing coil 142 can be fixedly connected with the first side plate 132.

[0137] Exemplarily, the first anti-shake coil 161 can be fixedly connected with the focusing carrier 13. The first anti-shake coil 161 can be located on the side of the bottom plate 131 facing the first side plate 132 and the second side plate 133, and fixedly connected with the bottom plate 131.

[0140] FIG. 10 is a partial structural schematic diagram III of the motor 1 shown in FIG. 3 in an embodiment.

[0141] As shown in FIG. 10, the focusing carrier 13 can be movably connected with the base 11 through the first guide 121. Exemplarily, the first groove 1121 of the base 11 and the second groove 1321 of the focusing carrier 13 can be oppositely arranged. At least part of the first guide 121 can be located in the first groove 1121, and at least part can be located in the second groove 1321.

[0142] It can be understood that the first guide 121 can reduce the frictional resistance when the focusing carrier 13 and the base 11 move relatively, reduce the power provided by the focusing driving mechanism 14, and thus reduce the size of the focusing driving mechanism 14. The first groove 1121 and the second groove 1321 can limit the first guide 121, and prevent the first guide 121 from being separated from the base 11 and the focusing carrier 13.

[0143] In other embodiments, the focusing carrier 13 can be movably connected to the base 11 in other ways. The specific embodiments are not limited herein.

[0144] FIG. 11 is a partial cross-sectional view of the motor 1 shown in FIG. 10 in an embodiment at line B-B.

[0145] Referring to FIGS. 10 and 11, and in combination with FIG. 2, the focusing magnetic member 141 can be fixedly connected to the base 11, and the focusing coil 142 can be fixedly connected to the focusing carrier 13. The focusing coil 142 can be located on one side of the focusing magnetic member 141, and can face the focusing magnetic member 141. The winding plane of the focusing coil 142 can be parallel to the first direction Z. It can be understood that the winding plane of the focusing coil 142 can be parallel to the first direction, which is beneficial to reduce the size of the motor 1 in the X-Y direction.

[0146] The focusing magnetic member 141 and the focusing coil 142 can cooperate to drive the focusing carrier 13 and the anti-shake carrier 15 to move along the first direction Z relative to the base 11. When the focusing carrier 13 and the anti-shake carrier 15 move along the first direction Z relative to the base 11, the anti-shake carrier 15 can drive the lens 2 to move along the first direction Z. At this time, the motor 1 can realize the focusing of the camera module 100. It can be understood that the focusing magnetic member 141 faces the focusing coil 142, which means that the focusing magnetic member 141 faces the winding plane of the focusing coil 142.

[0147] FIG. 12 is a partial structure diagram of the motor 1 shown in FIG. 3 in an embodiment.

[0148] As shown in FIGS. 11 and 12, the motor 1 further includes a focusing magnetic member 191. The focusing magnetic member 191 can be made of a material capable of generating a magnetic force with a magnet or other magnetic component, such as a ferromagnetic material.

[0149] The focusing magnetic member 191 can be fixed to the focusing carrier 13. The focusing magnetic member 191 can be fixedly connected to the first side plate 132 of the focusing carrier 13 and located between the second grooves 1321 of the first side plate 132.

[0150] Exemplarily, the focusing magnetic suction piece 191 and the focusing carrier 13 can be an integrally formed structure. It can be understood that the focusing magnetic suction piece 191 is integrally formed on the focusing carrier 13, which can reduce the assembly tolerance of the focusing magnetic suction piece and reduce the fluctuation of the magnetic force.

[0151] In other embodiments, the focusing magnetic suction piece 191 can also be fixedly connected to the focusing carrier 13 by welding, gluing or the like.

[0152] As shown in FIG. 11, exemplarily, the focusing magnetic suction piece 191 can be arranged to face the focusing magnetic piece 141. The magnetic force between the focusing magnetic suction piece 191 and the focusing magnetic piece 141 keeps the base 11, the first guide 121 and the focusing carrier 13 in contact. It can be understood that, during the focusing of the focusing carrier 13 along the first direction Z, the magnetic force between the focusing magnetic suction piece 191 and the focusing magnetic piece 141 keeps the base 11, the first guide 121 and the focusing carrier 13 in contact, which can prevent the focusing carrier 13 from tilting or overturning, thereby improving the stability of the movement of the motor 1.

[0153] Exemplarily, during the movement of the focusing carrier 13 and the anti-shake carrier 15 (see FIG. 2) relative to the base 11 along the first direction Z, the focusing carrier 13 and the anti-shake carrier 15 can satisfy: -0.5 mm (millimeter) ≤ dz ≤ 0.5 mm, where dz can represent the displacement of the focusing carrier 13 and the anti-shake carrier 15 relative to the base 11 along the Z-axis direction, and the negative value of dz means that the focusing carrier 13 and the anti-shake carrier 15 move relative to the base 11 along the negative direction of the Z-axis, and the positive value of dz means that the focusing carrier 13 and the anti-shake carrier 15 move relative to the base 11 along the positive direction of the Z-axis. For example, dz can be equal to -0.4 mm, -0.1 mm, 0, 0.2 mm, 0.3 mm or 0.4 mm, etc.

[0154] Exemplarily, during the movement of the focusing carrier 13 and the anti-shake carrier 15 relative to the base 11 along the first direction Z, the magnetic force of the focusing magnetic piece 141 and the focusing magnetic suction piece 191 in the X-axis direction can satisfy: -550 N (Newton) ≤ Fx ≤ -520 N, where Fx can represent the component of the magnetic force of the focusing magnetic suction piece 191 on the focusing magnetic piece 141 in the X-axis direction when the focusing carrier 13 and the anti-shake carrier 15 move relative to the base 11 along the Z-axis direction, and the negative value of Fx means that the component of the magnetic force of the focusing magnetic suction piece 191 on the focusing magnetic piece 141 in the X-axis direction is towards the negative direction of the X-axis. For example, Fx can be equal to -544 N, -538 N, -532 N or -528 N, etc.

[0155] Exemplarily, during the movement of the focusing carrier 13 and the anti-shake carrier 15 relative to the base 11 along the first direction Z, the magnetic force between the focusing magnetic member 141 and the focusing magnetic attraction member 191 in the Y-axis direction can satisfy: 0≤Fy≤1N, where Fy can represent the component of the magnetic force of the focusing magnetic attraction member 191 on the focusing magnetic member 141 in the Y-axis direction during the movement of the focusing carrier 13 and the anti-shake carrier 15 relative to the base 11 along the Z-axis direction. The positive value of Fy means that the component of the magnetic force of the focusing magnetic attraction member 191 on the focusing magnetic member 141 in the Y-axis direction is towards the positive direction of the Y-axis. For example, Fy can be equal to 0.3N, 0.4N, 0.5N, 0.6N or 0.7N, etc.

[0156] Exemplarily, during the movement of the focusing carrier 13 and the anti-shake carrier 15 relative to the base 11 along the first direction Z, the magnetic force between the focusing magnetic member 141 and the focusing magnetic attraction member 191 in the Z-axis direction can satisfy: -6N≤Fz≤6N, where Fz can represent the component of the magnetic force of the focusing magnetic attraction member 191 on the focusing magnetic member 141 in the Z-axis direction during the movement of the focusing carrier 13 and the anti-shake carrier 15 relative to the base 11 along the Z-axis direction. The negative value of Fz means that the component of the magnetic force of the focusing magnetic attraction member 191 on the focusing magnetic member 141 in the Z-axis direction is towards the negative direction of the Z-axis. The positive value of Fz means that the component of the magnetic force of the focusing magnetic attraction member 191 on the focusing magnetic member 141 in the Z-axis direction is towards the positive direction of the Z-axis. For example, Fz can be equal to -5N, -4N, -1N, 3N or 5N, etc.

[0157] Exemplarily, the magnetic force between the focusing magnetic member 141 and the focusing magnetic attraction member 191 is large, the focusing magnetic member 141 can be subjected to the magnetic force of the focusing magnetic attraction member 191, and the focusing carrier 13 and the anti-shake carrier 15 can return to the position with the displacement dz of 0 after the focusing is completed. In addition, the base 11, the first guide member 121 and the focusing carrier 13 can maintain the contact, so as to prevent the focusing carrier 13 from tilting or overturning, and thus the stability of the movement of the motor 1 is improved.

[0158] In other embodiments, dx, Fx, Fy and Fz can satisfy other ranges. The present application is not limited in this regard.

[0159] Exemplarily, under the condition that the focusing coil 142 is energized, the focusing driving force can be generated between the focusing coil 142 and the focusing magnetic member 141, so as to drive the focusing carrier 13 and the anti-shake carrier 15 to move relative to the base 11 along the first direction Z.

[0160] Exemplarily, the driving force generated between the focusing magnetic member 141 and the focusing coil 142 in the X-axis direction can satisfy: -70N≤Fx≤70N, where Fx can represent the component of the focusing driving force generated between the focusing coil 142 and the focusing magnetic member 141 in the X-axis direction, which the focusing carrier 13 receives when the focusing carrier 13 and the anti-shake carrier 15 move relative to the base 11 in the Z-axis direction. The positive value of Fx means that the component of the focusing driving force generated between the focusing coil 142 and the focusing magnetic member 141 in the X-axis direction, which the focusing carrier 13 receives, is towards the positive direction of the X-axis. The negative value of Fx means that the component of the focusing driving force generated between the focusing coil 142 and the focusing magnetic member 141 in the X-axis direction, which the focusing carrier 13 receives, is towards the negative direction of the X-axis. For example, Fx can equal to -61N, -33N, -17N, 17N, 48N or 61N, etc.

[0161] Exemplarily, the driving force generated between the focusing magnetic member 141 and the focusing coil 142 in the Y-axis direction can satisfy: -1N≤Fy≤1N, where Fy can represent the component of the focusing driving force generated between the focusing coil 142 and the focusing magnetic member 141 in the Y-axis direction, which the focusing carrier 13 receives when the focusing carrier 13 and the anti-shake carrier 15 move relative to the base 11 in the Z-axis direction. The negative value of Fy means that the component of the focusing driving force generated between the focusing coil 142 and the focusing magnetic member 141 in the Y-axis direction, which the focusing carrier 13 receives, is towards the negative direction of the Y-axis. The positive value of Fy means that the component of the focusing driving force generated between the focusing coil 142 and the focusing magnetic member 141 in the Y-axis direction, which the focusing carrier 13 receives, is towards the positive direction of the Y-axis. For example, Fy can equal to -0.7N, -0.5N, -0.1N, 0.1N, 0.3N or 0.6N, etc.

[0162] Exemplarily, the driving force generated between the focusing magnetic member 141 and the focusing coil 142 in the Z-axis direction can satisfy: 100N≤Fz≤150N, where Fz can represent the component of the focusing driving force generated between the focusing coil 142 and the focusing magnetic member 141 in the Z-axis direction, which the focusing carrier 13 receives when the focusing carrier 13 and the anti-shake carrier 15 move relative to the base 11 in the Z-axis direction. The positive value of Fz means that the component of the focusing driving force generated between the focusing coil 142 and the focusing magnetic member 141 in the Z-axis direction, which the focusing carrier 13 receives, is towards the positive direction of the Z-axis. For example, Fz can equal to 112N, 122N, 129N, 135N or 137N, etc.

[0163] Exemplarily, the focusing carrier 13 can complete focusing because the focusing driving force generated between the focusing coil 142 and the focusing magnetic member 141, which the focusing carrier 13 receives, is large.

[0164] In other embodiments, Fx, Fy, and Fz can each satisfy other ranges. The present application is not limited specifically.

[0170] As shown in FIG. 15, the first anti-shake magnetic member 163 can be fixedly connected with the anti-shake carrier 15. The first anti-shake magnetic member 163 can be located in the second mounting slot 151, for example. The first anti-shake magnetic member 163 can be a Halbach magnet array, for example. In other embodiments, the first anti-shake magnetic member 163 can be other types of magnets or components with magnetism. For example, the first anti-shake magnetic member 163 can adopt a double-magnet scheme, that is, composed of two magnets, the two magnets are arranged in the second direction X and have opposite polarities.

[0171] As shown in FIG. 15, the second anti-shake magnetic member 164 can be fixedly connected with the anti-shake carrier 15. The second anti-shake magnetic member 164 can be located in the second mounting slot 151, for example. The second anti-shake magnetic member 164 can be a Halbach magnet array, for example. In other embodiments, the second anti-shake magnetic member 164 can be other types of magnets or components with magnetism. For example, the second anti-shake magnetic member 164 can adopt a double-magnet scheme, that is, composed of two magnets, the two magnets are arranged in the third direction Y and have opposite polarities.

[0172] Fig. 16 is a schematic diagram of a partial structure of the motor 1 shown in Fig. 3 in an embodiment. Fig. 17 is a schematic diagram of a partial cross-section of the motor 1 shown in Fig. 16 at the line C-C in an embodiment.

[0173] As shown in Figs. 16 and 17, the anti-shake carrier 15 can be located at the inner side of the focusing carrier 13 and movably connected with the focusing carrier 13. In other words, the motor 1 of the present application is a motor structure of "focusing carrier anti-shake". The lens 2 (see Fig. 2) can be located at the inner side of the anti-shake carrier 15 and fixedly connected with the anti-shake carrier 15.

[0174] Exemplarily, the anti-shake carrier 15 can be movably connected with the focusing carrier 13 through the second guide 122. The fourth groove 152 of the anti-shake carrier 15 can be oppositely arranged with the third groove 1311 of the focusing carrier 13. At least part of the second guide 122 can be located in the third groove 1311 and at least part of the second guide 122 can be located in the fourth groove 152.

[0175] It can be understood that the second guide 122 can reduce the frictional resistance when the focusing carrier 13 and the anti-shake carrier 15 move relative to each other, reduce the driving force required to be provided by the anti-shake driving mechanism 16, and thus reduce the size of the anti-shake driving mechanism 16. The third groove 1311 and the fourth groove 152 can limit the second guide 122, so as to prevent the second guide 122 from being separated from between the focusing carrier 13 and the anti-shake carrier 15.

[0176] It can be understood that the second guide 122 is a group of balls, the movable connection between the focusing carrier 13 and the anti-shake carrier 15 is achieved through the second guide 122, the frictional resistance between the second guide 122 and the anti-shake carrier can be reduced while ensuring sufficient supporting force, the requirement for the size of the driving force during the movement of the anti-shake carrier can be reduced, that is, the size of the first anti-shake coil 161 and / or the first anti-shake magnetic member 163, the second anti-shake coil 162 and / or the second anti-shake magnetic member 164 can be reduced, and the motor 1 can be miniaturized. Exemplarily, compared with the diameter of a large ball in the prior art, the diameter of each ball in the second guide 122 in the embodiment is smaller, and the interval between the anti-shake carrier 15 and the base 11 can be shortened, and the motor 1 can be thinned. In addition, the second guide 122 can provide multi-point support for the anti-shake carrier 15, so as to disperse stress and prevent the balls in the second guide 122 from being deformed due to excessive concentration of force in a single direction, and the reliability of the second guide 122 in supporting the anti-shake carrier 15 and other structural members such as the lens 2 (see Fig. 2) can be improved.

[0177] In other embodiments, the anti-shake carrier 15 can also be movably connected with the focusing carrier 13 in other manners. The specific manners are not limited in the present application.

[0178] Fig. 18 is a partial cross-sectional schematic view of an embodiment of the motor 1 shown in Fig. 16 at line D-D.

[0179] As shown in Figs. 17 and 18, exemplarily, the first anti-shake coil 161 can be located at one side of the first anti-shake magnetic member 163, the first anti-shake coil 161 can be arranged facing the first anti-shake magnetic member 163, and the first anti-shake coil 161 and the first anti-shake magnetic member 163 can be arranged along the first direction Z. The first anti-shake coil 161 and the first anti-shake magnetic member 163 can cooperate to drive the anti-shake carrier 15 to move relative to the focusing carrier 13 along the second direction X. Wherein, the first anti-shake coil 161 is arranged facing the first anti-shake magnetic member 163, which means that the winding plane of the first anti-shake coil 161 faces the first anti-shake magnetic member 163. For example, the winding plane of the first anti-shake coil 161 can be arranged parallel to the X-Y plane.

[0180] Fig. 19 is a partial cross-sectional schematic view of an embodiment of the motor 1 shown in Fig. 16 at line E-E.

[0181] As shown in Figs. 17 and 19, exemplarily, the second anti-shake coil 162 can be located at one side of the second anti-shake magnetic member 164, the second anti-shake coil 162 can be arranged facing the second anti-shake magnetic member 164, and the second anti-shake coil 162 and the second anti-shake magnetic member 164 can be arranged along the first direction Z. The second anti-shake coil 162 and the second anti-shake magnetic member 164 can cooperate to drive the anti-shake carrier 15 to move relative to the focusing carrier 13 along the third direction Y. Wherein, the second anti-shake coil 162 is arranged facing the second anti-shake magnetic member 164, which means that the winding plane of the second anti-shake coil 162 faces the second anti-shake magnetic member 164. For example, the winding plane of the second anti-shake coil 162 can be arranged parallel to the X-Y plane.

[0182] It can be understood that, in the present embodiment, the first anti-shake coil 161 and the first anti-shake magnetic member 163 are arranged along the first direction Z, and the first anti-shake coil 161 is located at one side of the first anti-shake magnetic member 163. The second anti-shake coil 162 and the second anti-shake magnetic member 164 are arranged along the first direction Z, and the second anti-shake coil 162 is located at one side of the second anti-shake magnetic member 164. In this way, it is beneficial to reduce the size of the motor 1 in the X-Y direction.

[0183] In other embodiments, the number of the first anti-shake coils 161 can be two, and the first anti-shake coils 161 can be respectively located at two sides of the first anti-shake magnetic member 163. The number of the second anti-shake coils 162 can be two, and the second anti-shake coils 162 can be respectively located at two sides of the second anti-shake magnetic member 164. The specific number of the first anti-shake coils 161 and the second anti-shake coils 162 is not limited in the present application.

[0184] Referring to FIGS. 18 and 19, and in combination with FIG. 2, the first anti-shake coil 161 and the first anti-shake magnetic member 163 can cooperate, and the second anti-shake coil 162 and the second anti-shake magnetic member 164 can cooperate, which can be used to drive the anti-shake carrier 15 to drive the lens 2 to move relative to the base 11 and the focusing carrier 13 in the X-Y plane in any direction, so as to offset the shaking stroke of the lens 2 in the X-Y plane, and thus realize optical anti-shake of the camera module 100 and improve the imaging quality of the camera module 100.

[0185] It can be understood that in the scheme in which the focusing carrier 13 is located inside the anti-shake carrier 15, the anti-shake carrier 15 needs to drive the focusing carrier 13 and the lens 2 to move relative to the base 11 in the X-Y plane. At this time, there are more moving structural members in the optical anti-shake process, the total weight is larger, the anti-shake carrier 15 needs a larger driving force, and the motor 1 needs a larger anti-shake driving mechanism 16 to meet the requirement of the larger anti-shake driving force. Therefore, the motor 1 can be provided with one first anti-shake coil 161 on each side of the first anti-shake magnetic member 163, and one second anti-shake coil 162 on each side of the second anti-shake magnetic member 164. However, the scheme in which the two anti-shake coils are respectively located on the two sides of the anti-shake magnetic member increases the size of the motor 1 in the second direction X and the third direction Y, which is not conducive to the miniaturization of the motor 1, and the assembly process of the motor 1 is more complex.

[0186] It can be understood that in the scheme in which the anti-shake carrier 15 of the present embodiment is located inside the focusing carrier 13, the anti-shake driving mechanism 16 does not need to drive the focusing carrier 13 to move in the first direction Z, the maximum driving force required by the anti-shake driving mechanism 16 is smaller, and it can not be necessary to provide one first anti-shake coil 161 on each side of the first anti-shake magnetic member 163 and one second anti-shake coil 162 on each side of the second anti-shake magnetic member 164, the size of the anti-shake driving mechanism 16 is smaller, the overall size of the motor 1 is smaller, and the assembly process of the motor 1 is simpler.

[0187] FIG. 20 is a partial cross-sectional schematic view of one embodiment of the motor 1 shown in FIG. 16 at the F-F line.

[0188] As shown in FIGS. 17 and 20, the motor 1 can also include an anti-shake magnetic attraction member 192. The anti-shake magnetic attraction member 192 can be made of a material capable of generating a magnetic force with a magnet or other magnetic component, such as a ferromagnetic material, etc.

[0189] Exemplarily, the anti-shake magnetic attraction member 192 can be fixed to the focusing carrier 13, and the anti-shake magnetic attraction member 192 can be located on the side of the bottom plate 131 of the focusing carrier 13 close to the first anti-shake coil 161 and the second anti-shake coil 162. In an embodiment, the number of anti-shake magnetic attraction members 192 can be multiple. For example, the number of anti-shake magnetic attraction members 192 can be four. Two anti-shake magnetic attraction members 192 can be located between the bottom plate 131 and the first anti-shake coil 161, and two anti-shake magnetic attraction members 192 can be located between the bottom plate 131 and the second anti-shake coil 162.

[0190] In other embodiments, the anti-shake magnetic attraction member 192 can also have other arrangement modes. For example, the number of anti-shake magnetic attraction members 192 can be one, the anti-shake magnetic attraction member 192 can be located between the bottom plate 131 and the first anti-shake coil 161, or the anti-shake magnetic attraction member 192 can be located between the bottom plate 131 and the second anti-shake coil 162. The specific embodiments are not limited herein.

[0191] Exemplarily, the anti-shake magnetic attraction member 192 can be located on the side of the first anti-shake coil 161 away from the first anti-shake magnetic member 163 and face the first anti-shake magnetic member 163, and the anti-shake magnetic attraction member 192 and the first anti-shake magnetic member 163 can have a magnetic force. The anti-shake magnetic attraction member 192 can be located on the side of the second anti-shake coil 162 away from the second anti-shake magnetic member 164 and face the second anti-shake magnetic member 164, and the anti-shake magnetic attraction member 192 and the second anti-shake magnetic member 164 can have a magnetic force.

[0192] It can be understood that the magnetic force between the first anti-shake magnetic member 163 and the anti-shake magnetic attraction member 192 and the magnetic force between the second anti-shake magnetic member 164 and the anti-shake magnetic attraction member 192 enable the anti-shake carrier 15 to be subjected to an anti-shake magnetic force, so that the anti-shake carrier 15, the second guide member 122 and the focusing carrier 13 remain in contact, the connection stability between the anti-shake carrier 15, the second guide member 122 and the focusing carrier 13 is ensured, and the anti-shake carrier 15 is prevented from being separated from the focusing carrier 15 and the like.

[0193] Exemplarily, during the movement of the anti-shake carrier 15 relative to the focusing carrier 13 in the X-Y plane, the anti-shake carrier 15 can satisfy -0.2mm≤dx≤0.2mm, where dx can represent the displacement of the anti-shake carrier 15 in the X-axis direction, and the negative value of dx indicates that the anti-shake carrier 15 moves in the negative direction of the X-axis relative to the focusing carrier 13, and the positive value of dx indicates that the anti-shake carrier 15 moves in the positive direction of the X-axis relative to the focusing carrier 13. For example, dx can be equal to -0.16mm, -0.1mm, 0, 0.1mm or 0.16mm, etc.

[0194] Exemplarily, during the movement of the anti-shake carrier 15 relative to the focusing carrier 13 in the X-Y plane, the anti-shake magnetic force received by the anti-shake carrier 15 in the X-axis direction can satisfy: -20N≤Fx≤20N, where Fx can represent the component of the anti-shake magnetic force received by the anti-shake carrier 15 in the X-axis direction when the anti-shake carrier 15 moves relative to the focusing carrier 13 in the X-Y plane.

The positive value of Fx means that the component of the anti-shake magnetic force received by the anti-shake carrier 15 in the X-axis direction is towards the positive direction of the X-axis when the anti-shake carrier 15 moves relative to the focusing carrier 13 in the X-Y plane. For example, Fx can be equal to -14N, -13N, -0.2N, 0, 0.2N, or 13N, etc.

For example, Fy can be equal to -12N, -10N, -6N, 0, 5N, 8N, or 12N, etc.

[0196] Exemplarily, during the movement of the anti-shake carrier 15 relative to the focusing carrier 13 in the X-Y plane, the anti-shake magnetic force received by the anti-shake carrier 15 in the Z-axis direction can satisfy: 200N≤Fz≤210N, where Fz can represent the component of the anti-shake magnetic force received by the anti-shake carrier 15 in the Z-axis direction when the anti-shake carrier 15 moves relative to the focusing carrier 13 in the X-Y plane. The negative value of Fz means that the component of the anti-shake magnetic force received by the anti-shake carrier 15 in the Z-axis direction is towards the negative direction of the Z-axis when the anti-shake carrier 15 moves relative to the focusing carrier 13 in the X-Y plane. The positive value of Fz means that the component of the anti-shake magnetic force received by the anti-shake carrier 15 in the Z-axis direction is towards the positive direction of the Z-axis when the anti-shake carrier 15 moves relative to the focusing carrier 13 in the X-Y plane. For example, Fz can be equal to 200N, 204N, 207N, 210N, or 215N, etc.

[0197] Exemplarily, during the movement of the anti-shake carrier 15 relative to the focusing carrier 13 in the X-Y plane, the anti-shake magnetic force acting on the anti-shake carrier 15 is greater, and the anti-shake carrier 15 can be restored to the position where the displacement dx of the anti-shake carrier 15 is 0 by the magnetic force.

[0198] In other embodiments, Fx, Fy and Fz can all satisfy other ranges. The present application is not limited in particular.

[0199] Exemplarily, under the condition that the first anti-shake coil 161 is powered, an anti-shake driving force can be generated between the first anti-shake coil 161 and the first anti-shake magnetic piece 163, thereby driving the anti-shake carrier 15 to move relative to the focusing carrier 13 in the X-Y plane along the second direction X.

[0200] Exemplarily, during the movement of the anti-shake carrier 15 relative to the focusing carrier 13 along the second direction X, the anti-shake driving force acting on the anti-shake carrier 15 in the X-axis direction can satisfy: -100N≤Fx≤-70N, where Fx can represent the component of the anti-shake driving force acting on the anti-shake carrier 15 in the X-axis direction when the anti-shake carrier 15 moves relative to the focusing carrier 13 along the second direction X, and the negative value of Fx indicates that the component of the anti-shake driving force acting on the anti-shake carrier 15 in the X-axis direction is directed towards the negative direction of the X-axis when the anti-shake carrier 15 moves relative to the focusing carrier 13 along the second direction X.

The positive value of Fy indicates that the component of the anti-shake driving force acting on the anti-shake carrier 15 in the Y-axis direction is directed towards the positive direction of the Y-axis when the anti-shake carrier 15 moves relative to the focusing carrier 13 along the second direction X. For example, Fy can be equal to -1N, -0.8N, -0.4N, 0, 0.4N, 0.8N or 1N, etc.

[0204] In other embodiments, Fx, Fy, and Fz can all satisfy other ranges. The present application is not limited in this regard.

[0205] Exemplarily, under the condition that the second anti-vibration coil 162 is energized, the anti-vibration driving force can be generated between the second anti-vibration coil 162 and the second anti-vibration magnetic member 164, so as to drive the anti-vibration carrier 15 to move relative to the focusing carrier 13 along the third direction Y in the X-Y plane.

The positive value of Fz means that the component of the anti-shake driving force in the Z-axis direction that the anti-shake carrier 15 receives when the anti-shake carrier 15 moves relative to the focusing carrier 13 along the third direction Y is towards the positive direction of the Z-axis. For example, Fz can equal to -26N, -18N, -5N, -0.1N, 0, 10N, 23N or 26N, etc.

[0209] It can be understood that the larger the anti-shake driving force in the third direction Y that the anti-shake carrier 15 receives, the more the anti-shake carrier 15 can move relative to the focusing carrier 13 along the third direction Y.

[0210] In other embodiments, Fx, Fy and Fz can all satisfy other ranges. The present application is not limited in this regard.

[0211] The above describes the related structure of the motor 1 in some embodiments in combination with related drawings, and the following describes the related technical problems that the motor 1 in some embodiments can solve in combination with related drawings.

[0212] Please refer to FIG. 16 to FIG. 19, it can be understood that, in the embodiment, the anti-vibration carrier 15 is located at the inner side of the focusing carrier 13, that is, the motor 1 of the embodiment is a motor structure of "focusing-to-anti-vibration", the first anti-vibration coil 161 and the first anti-vibration magnetic member can cooperate, the second anti-vibration coil 162 and the second anti-vibration magnetic member 164 can cooperate, for driving the anti-vibration carrier 15 to complete optical anti-vibration, that is, the load of the anti-vibration driving mechanism 16 of the embodiment is smaller. Then, the driving force required by the anti-vibration driving mechanism 16 is smaller, the size of the anti-vibration driving mechanism 16 is smaller, and the size of the motor 1 is smaller, which is beneficial to realize the miniaturization of the motor 1. In addition, the anti-vibration carrier 15 is movably connected with the focusing carrier 13 through the ball group, the frictional resistance between the anti-vibration carrier 15 and the focusing carrier 13 is smaller, the anti-vibration driving force required by the anti-vibration carrier 15 is smaller, the size of the anti-vibration driving mechanism 16 is smaller, and the size of the motor 1 is smaller, which is beneficial to realize the miniaturization of the motor 1.

[0213] Please refer to FIG. 18 and FIG. 19, it can be understood that, in the focusing process, the focusing coil 142 can move along the first direction Z with the focusing carrier 13, in other words, in the focusing process, the focusing driving mechanism 14 of the embodiment is a moving coil design. In this way, it can be avoided that the focusing magnetic member 141 generates magnetic interference to the first anti-vibration magnetic member 163, the second anti-vibration magnetic member 164 or other magnetic structural members.

[0214] Please refer to FIG. 18 and FIG. 19, it can be understood that, the focusing coil 142 is fixedly connected with the focusing carrier 13. The first anti-vibration coil 161 and the second anti-vibration coil 162 are both fixedly connected with the focusing carrier 13, and the motor 1 can be electrically connected with the focusing coil 142, the first anti-vibration coil 161 and the second anti-vibration coil 162 by arranging structural members on the focusing carrier 13. In this way, compared with the scheme of arranging the focusing coil 142 on the focusing carrier 13 and arranging the first anti-vibration coil 161 and the second anti-vibration coil 162 on the anti-vibration carrier 15, the electrical connection mode of the scheme of the embodiment is simpler.

[0215] Please refer to FIG. 16, FIG. 18 and FIG. 19, it can be understood that, by arranging the first anti-vibration coil 161 and the first anti-vibration magnetic member 163 along the first direction Z, and arranging the second anti-vibration coil 162 and the second anti-vibration magnetic member 164 along the first direction Z, the size of the motor 1 in the X-Y direction can be reduced.

[0216] Please refer to FIG. 16, FIG. 18 and FIG. 19, it can be understood that the first anti-vibration coil 161 is located on one side of the first anti-vibration magnetic member 163, and the second anti-vibration coil 162 is located on one side of the second anti-vibration magnetic member 164. The anti-vibration driving mechanism 16 is more reasonable in arrangement, the structure of the motor 1 is simpler, and the assembly process of the motor 1 can be simplified. In addition, the risk of short circuit between the first anti-vibration coil 161, the second anti-vibration coil 162, the first anti-vibration magnetic member 163, the second anti-vibration magnetic member 164 and other structural members can be reduced.

[0217] Please refer to FIG. 16, it can be understood that the first anti-vibration magnetic member 163 and the second anti-vibration magnetic member 164 are both Halbach magnet arrays. The anti-vibration driving force generated by the cooperation of the first anti-vibration coil 161 and the first anti-vibration magnetic member 163 is approximately along the second direction X, and the anti-vibration driving force generated by the cooperation of the second anti-vibration coil 162 and the second anti-vibration magnetic member 164 is approximately along the third direction Y. The anti-vibration driving force is larger, which can drive the anti-vibration carrier 15 to complete optical anti-vibration.

[0218] Please refer to FIG. 11, it can be understood that the magnetic force between the focusing magnetic attraction member 191 and the focusing magnetic member 141 makes the base 11, the first guide member 121 and the focusing carrier 13 keep in contact. During the focusing process of the motor 1, the focusing carrier 13 is not easy to be tilted or the like due to movement. In addition, the focusing magnetic attraction member 191 and the focusing carrier 13 are integrally formed, so that the assembly tolerance of the focusing magnetic attraction member 191 is small, thereby reducing the fluctuation of the magnetic force between the focusing magnetic attraction member 191 and the focusing magnetic member 141, and improving the movement stability of the motor 1. Compared with other focusing magnetic attraction schemes, the focusing magnetic attraction scheme of the present embodiment is simpler in structure.

[0219] Please refer to FIG. 17 and FIG. 20, it can be understood that the magnetic force between the anti-vibration magnetic attraction member 192 and the first anti-vibration magnetic member 163, the second anti-vibration magnetic member 164 makes the focusing carrier 13, the second guide member 122 and the anti-vibration carrier 15 keep in contact. During the anti-vibration process of the motor 1, the anti-vibration carrier 15 is not easy to be tilted or the like due to movement. In addition, compared with other anti-vibration magnetic attraction schemes, the anti-vibration magnetic attraction scheme of the present embodiment is simpler in structure.

[0220] The above describes the related structure of the motor 1 in some embodiments and the technical problems solved by the motor 1 in some embodiments in combination with related drawings.

Exemplarily, the first fixed part 171 of the electric connector 17 can fixedly connect the base 11. The first fixed part 171 can be fixedly connected with the bottom 111 of the base 11.

[0229] FIG. 26 is a partial structural schematic diagram nine of the motor 1 shown in FIG. 3 in an embodiment. FIG. 27 is a partial sectional schematic diagram of the motor 1 shown in FIG. 26 in an embodiment.

[0230] As shown in FIG. 26 and FIG. 27, the second fixed part 173 of the electric connector 17 can be fixedly connected with the focusing carrier 13. Exemplarily, the first part 1731 of the second fixed part 173 can be fixedly connected with the second side plate 133 of the focusing carrier 13, and the second part 1732 of the second fixed part 173 of the electric connector 17 can be located on the side of the bottom plate 131 of the focusing carrier 13 close to the base 11, and the second part 1732 can be fixedly connected with the bottom plate 131. The deformation part 172 of the electric connector 17 can be located between the focusing carrier 13 and the bottom 111 of the base 11.

[0231] Exemplarily, the driving chip 193 can be located on the side of the first part 1731 of the second fixed part 173 close to the focusing carrier 13. It can be understood that, compared with the scheme that the driving chip 193 is located on the side of the electric connector 17 away from the focusing carrier 13, the first part 1731 of the second fixed part 173 of the electric connector 17 in the embodiment can not need to be bent by a larger angle towards the direction of the second part 1732.

[0232] Please refer to FIG. 26 and FIG. 27, and combine with FIG. 22 and FIG. 23, it is exemplarily shown that, in the process that the focusing carrier 13 moves relative to the base 11 along the first direction Z, the position of the first fixed part 171 of the electric connector 17 relative to the base 11 can be unchanged, the second fixed part 173 of the electric connector 17 can move along with the focusing carrier 13 relative to the base 11 along the first direction Z, and the deformation part 172 of the electric connector 17 can be deformed, and the deformation part 172 can have elastic force.

[0233] It can be understood that the focusing coil 142 can be electrically connected with the base 11 through the second fixed part 173 of the electric connector 17, and the first anti-shake coil 161 and the second anti-shake coil 162 can be electrically connected with the base 11 through the second fixed part 173 of the electric connector 17. In this way, the structure of the electric connection between the focusing coil 142, the first anti-shake coil 161 and the second anti-shake coil 162 and the base 11 is relatively simple, and the structure of the motor 1 is relatively simple. In addition, the deformation part 172 is connected between the first fixed part 171 and the second fixed part 173, and in the process that the second fixed part 173 moves along with the focusing carrier 13 relative to the base 11 along the first direction Z, the deformation part 172 can be deformed, which can ensure the electrical connection between the focusing coil 142, the first anti-shake coil 161 and the second anti-shake coil 162 and the base 11, and can not affect the movement of the focusing carrier 13.

[0234] As shown in FIG. 21 to FIG. 23, exemplarily, the deformation part 172 can be provided with a through hole 1721. The through hole 1721 can be a strip-shaped hole, and the through hole 1721 can extend along the length extension direction of the deformation part 172.

[0235] Exemplarily, the deformation portion 172 of the electrical connector 17 of some embodiments is not provided with the through hole 1721. It can be understood that, compared with the scheme that the deformation portion 172 is not provided with the through hole 1721, the through hole 1721 of the deformation portion 172 in the embodiment makes the deformation portion 172 be bifurcated, the width of the deformation portion 172 along the second direction X or the third direction Y is smaller, the K value of the electrical connector 17 of the embodiment can be reduced, and the elastic force of the electrical connector 17 can be reduced, wherein the K value is the elastic coefficient.

[0236] Exemplarily, the electrical connector 17 of the deformation portion 172 without the through hole 1721 satisfies: 2≤Kz≤5, 137≤Kx≤142, 278≤Ky≤283, wherein Kz can represent the K value of the electrical connector 17 in the Z-axis direction. Kx can represent the K value of the electrical connector 17 in the X-axis direction. Ky can represent the K value of the electrical connector 17 in the Y-axis direction. For example, Kz can be equal to 2, 3.8 or 4, etc. Kx can be equal to 138, 139.6 or 141, etc. Ky can be equal to 278, 280.4 or 283, etc.

[0237] Exemplarily, the electrical connector 17 of the deformation portion 172 with the through hole 1721 satisfies: 1≤Kz≤3, 55≤Kx≤62, 45≤Ky≤53, for example, Kz can be equal to 1, 2 or 3, etc., Kx can be equal to 56, 58 or 60, etc., and Ky can be equal to 46, 48 or 51, etc. In other embodiments, Kz, Kx and Ky can all satisfy other ranges. The specific embodiments are not limited herein.

[0238] It can be understood that Kz, Kx and Ky are schematically given by the dashed lines with arrows in FIGS. 21-23. The length of the dashed lines in FIGS. 21-23 does not represent the actual size of Kz, Kx and Ky.

[0239] In an embodiment, the K values of the electrical connector 17 of the deformation portion 172 without the through hole 1721 and the K values of the electrical connector 17 of the deformation portion 172 with the through hole 1721 are compared as shown in Table 1.

[0240] Table 1 Comparison of K values of the electrical connector 17 of the deformation portion 172 without the through hole 1721 and the K values of the electrical connector 17 of the deformation portion 172 with the through hole 1721

[0241] It can be understood that, compared with the electrical connector 17 of the deformation portion 172 without the through hole 1721, the K value of the electrical connector 17 of the deformation portion 172 with the through hole 1721 is reduced in the Z-axis direction, the X-axis direction and the Y-axis direction. Then, in the case that the same deformation amount of the deformation portion 172 is generated, the elastic force of the electrical connector 17 of the present embodiment is smaller. In this way, in the process that the second fixed portion 173 of the electrical connector 17 moves with the focusing carrier 13 and the anti-shake carrier 15 along the first direction Z, the elastic force of the electrical connector 17 is smaller, the influence of the elastic force of the electrical connector 17 on the focusing process is smaller, thereby being beneficial to improve the stability of the movement of the motor 1. In addition, the deformation of the electrical connector 17 is caused by the movement of the focusing carrier 13 and the anti-shake carrier 15 along the first direction Z, the deformation of the electrical connector 17 is smaller, the driving force required by the deformation is smaller, and the driving force required to be provided by the focusing driving mechanism 14 is smaller, which is beneficial to reduce the volume of the focusing driving mechanism 14.

[0242] As shown in FIGS. 26 and 27, the focusing carrier 13 exemplarily further comprises a first protruding column 136. In an embodiment, the number of the first protruding column 136 can be multiple, and the multiple first protruding columns 136 can be respectively protruded on the first side plate 132, the second side plate 133, the first protruding block 134 and the second protruding block 135 of the focusing carrier 13.

[0243] Exemplarily, the anti-shake carrier 15 further comprises a second protruding column 153, which can be protruded on one side of the anti-shake carrier 15. In an embodiment, the number of the second protruding column 153 can be multiple.

[0244] Exemplarily, the motor 1 further comprises a spring 194. In an embodiment, the number of the spring 194 can be multiple, for example, the number of the spring 194 can be four.

[0245] Exemplarily, the spring 194 can adopt a metal spring structure. The spring 194 can be deformed under external force, in other words, the spring 194 can be stretched or compressed under the action of external force. When the anti-shake carrier 15 does not displace relative to the focusing carrier 13, the spring 194 can be in a state of no deformation. In other embodiments, when the anti-shake carrier 15 does not displace relative to the focusing carrier 13, the spring 194 can also be in a state of being stretched or compressed.

[0246] Exemplarily, one end of the spring 194 can be sleeved on the first protruding column 136 of the focusing carrier 13 and fixedly connected with the focusing carrier 13, and the other end can be sleeved on the second protruding column 153 of the anti-shake carrier 15 and fixedly connected with the anti-shake carrier 15, and the spring 194 can be connected between the focusing carrier 13 and the anti-shake carrier 15.

[0247] It can be understood that, since the leaf spring 194 is connected between the anti-shake carrier 15 and the focusing carrier 13, the movement of the anti-shake carrier 15 causes the leaf spring 194 to elastically deform and have an elastic force, so that the anti-shake carrier 15 is reset and can return to the position where the displacement dx is 0. The leaf spring 194 can also provide an anti-torsion force to the anti-shake carrier 15 to hinder the rotation of the anti-shake carrier 15. In addition, in the embodiment, the first anti-shake coil 161 is located on one side of the first anti-shake magnetic member 163, and the second anti-shake coil 162 is located on one side of the second anti-shake magnetic member 164, which can reduce the risk of short circuit between the first anti-shake coil 161, the second anti-shake coil 162 and the structural members such as the leaf spring 194, and improve the reliability of the motor 1.

[0249] Please refer to FIGS. 28 and 29, and in combination with FIG. 26, the motor 1 further includes a wire 195. The wire 195 can be embedded in the focusing carrier 13. Exemplarily, a part of the wire 195 can be embedded in the bottom plate 131 of the focusing carrier 13 and exposed relative to the bottom plate 131. A part of the wire 195 can be embedded in the first side plate 132 of the focusing carrier 13 and exposed relative to the first side plate 132.

[0252] In other embodiments, the wires 195 can be fixedly connected to the focusing carrier 13 by welding, gluing or the like. The wires 195 can have different structures, numbers, etc. and can be arranged flexibly according to actual needs.

[0253] As shown in FIG. 29, the wires 195 can be fixedly connected to and electrically connected with the electrical connector 17. Exemplarily, the bent portions 1951 of the wires 195 can be arranged along the first direction Z and fixedly connected to the pin ends 17321 of the second portions 1732 of the second fixed portions 173 of the electrical connector 17. It can be understood that the bent portions 1951 of the wires 195 make the connection process between the wires 195 and the electrical connector 17 simpler.

[0254] Exemplarily, the bent portions 1951 can be electrically connected to the pin ends 17321 by welding or the like. In other embodiments, the bent portions 1951 can be electrically connected to the pin ends 17321 by other manners.

[0255] Please refer to FIGS. 27-29 and FIG. 18, the focusing coil 142 can be electrically connected to the driving chip 193 through the first portions 1731 of the second fixed portions 173 of the electrical connector 17, and the wires 195 can form a current loop with the first portions 1731 of the second fixed portions 173 of the electrical connector 17, the focusing coil 142 and the driving chip 193. It can be understood that the driving chip 193 can control the current situation (e.g. whether to pass current or the size of the current when passing current, etc.) of the focusing coil 142 through the wires 195 and the first portions 1731 of the second fixed portions 173 of the electrical connector 17, to control the focusing process of the motor 1.

[0256] As shown in FIGS. 26-29, the first anti-shake coil 161 can be electrically connected to the driving chip 193 through the second portions 1732 of the second fixed portions 173 of the electrical connector 17, and the wires 195 can form a current loop with the second portions 1732 of the second fixed portions 173 of the electrical connector 17, the first anti-shake coil 161 and the driving chip 193. The second anti-shake coil 162 can be electrically connected to the driving chip 193 through the second portions 1732 of the second fixed portions 173 of the electrical connector 17, and the wires 195 can form a current loop with the second portions 1732 of the second fixed portions 173 of the electrical connector 17, the second anti-shake coil 162 and the driving chip 193. It can be understood that the driving chip 193 can control the current situation (e.g. whether to pass current or the size of the current when passing current, etc.) of the first anti-shake coil 161 and the second anti-shake coil 162 through the wires 195 and the second portions 1732 of the second fixed portions 173 of the electrical connector 17, to control the optical anti-shake process of the motor 1.

[0257] Second embodiment: please refer to FIG. 30, which is a structural schematic diagram of the electric connector 17 shown in FIG. 21 in another embodiment. It can be understood that the relevant design of the motor 1 in the first embodiment can also be directly applied to the structural design of the motor 1 shown in the present embodiment without conflict. Among them, the technical contents of the motor 1 in the first embodiment will not be repeated in the present embodiment.

[0258] Exemplarily, the electric connector 17 includes a first fixed part 171, a deformation part 172, and a second fixed part 173, and the deformation part 172 is connected between the first fixed part 171 and the second fixed part 173.

[0259] Exemplarily, in the thickness direction of the deformation part 172, the deformation part 172 includes a plurality of layers of deformation sub-parts 1722.

[0260] Exemplarily, each layer of the deformation sub-part 1722 includes a first end part 17221 and a second end part 17222. The first end part 17221 of each layer of the deformation sub-part 1722 can be fixedly connected with the first fixed part 171, and the second end part 17222 of each layer of the deformation sub-part can be fixedly connected with the second fixed part 173. The deformation sub-parts 1722 of adjacent two layers can be spaced apart to form a hollow region 17223. In other words, the deformation part 172 of the electric connector 17 in the present embodiment is arranged in layers. In other embodiments, the first end part 17221 of each layer of the deformation sub-part 1722 can be fixedly connected with each other and with the first fixed part 171. The second end part 17222 of each layer of the deformation sub-part 1722 can be fixedly connected with each other and with the second fixed part 173.

[0261] Exemplarily, compared with the scheme that the deformation part 172 is not arranged in layers, the deformation part 172 arranged in layers in the present embodiment makes the thickness of the deformation part 172 in the first direction Z smaller, and the K value of the electric connector 17 in the present embodiment can be reduced.

[0262] It can be understood that, compared with the electrical connector 17 without the layered deformation portion 172, the K value of the electrical connector 17 with the layered deformation portion 172 in the embodiment is reduced. In this way, during the movement of the second fixing portion 173 of the electrical connector 17 along the first direction Z with the focusing carrier 13 (see FIG. 27) and the anti-shake carrier 15 (see FIG. 27), the elastic force of the electrical connector 17 is smaller, the influence of the elastic force of the electrical connector 17 on the focusing process is smaller, and thus the stability of the movement of the motor 1 is improved. In addition, the deformation of the electrical connector 17 is caused by the movement of the focusing carrier 13 and the anti-shake carrier 15 along the first direction Z, the deformation of the electrical connector 17 is smaller, the driving force required for the deformation is smaller, and the driving force required to be provided by the focusing driving mechanism 14 is smaller, which is beneficial to reduce the size of the focusing driving mechanism 14.

[0263] Exemplarily, each layer of the deformation sub-portion 1722 can also be provided with a through hole 17224, and the through hole 17224 of the deformation sub-portion 1722 can be in a strip shape and can extend along the length extension direction of the deformation sub-portion 1722. In other embodiments, each layer of the deformation sub-portion 1722 can also not be provided with the through hole 17224.

[0264] Third embodiment: please refer to FIG. 31, which is a structural schematic diagram of the electrical connector 17 in another embodiment shown in FIG. 21. It can be understood that the related design of the motor 1 in the first embodiment and / or the second embodiment can also be directly applied to the structural design of the motor 1 shown in the embodiment without conflict. In addition, the same technical contents as those of the motor 1 shown in the first embodiment and / or the second embodiment will not be described herein.

[0265] Exemplarily, the electrical connector 17 includes a first fixing portion 171, a deformation portion 172, and a second fixing portion 173, and the deformation portion 172 is connected between the first fixing portion 171 and the second fixing portion 173.

[0266] Exemplarily, at least part of the deformation portion 172 can be curved. In other words, the deformation portion 172 of the present embodiment can be elongated. Compared with the case where the deformation portion 172 is not elongated, the K value of the electrical connector 17 of the present embodiment can be reduced. In this way, during the movement of the second fixing portion 173 of the electrical connector 17 along the first direction Z with the focus carrier 13 (see FIG. 27) and the anti-shake carrier 15 (see FIG. 27), the elastic force of the electrical connector 17 is smaller, and the influence of the elastic force of the electrical connector 17 on the focusing process is smaller, thereby facilitating the improvement of the stability of the movement of the motor 1. In addition, the deformation of the electrical connector 17 is caused by the movement of the focus carrier 13 and the anti-shake carrier 15 along the first direction Z, and the deformation of the electrical connector 17 is smaller, and the driving force required for the deformation is smaller, and the driving force required to be provided by the focusing driving mechanism 14 is smaller, thereby facilitating the reduction of the size of the focusing driving mechanism 14.

[0267] In other embodiments, at least part of the deformation portion 172 can also be spiral, polyline, etc.

[0268] The above describes the related structures in some embodiments of the motor 1 in combination with the related drawings, and the related structures of the motor 1 in some embodiments will be described in combination with the related drawings. It can be understood that the related designs of the motor 1 shown in the foregoing can also be directly applied to the structural design of the motor 1 shown in the following without conflict.

The pressing piece 181 can be fixed to the side of the anti-shake carrier 15 away from the base 11, and the pressing piece 181 can also be fixedly connected with the second side plate 133 of the focus carrier 13. It can be understood that the pressing piece 181 can cooperate with the focus carrier 13 to limit the movement stroke of the anti-shake carrier 15 in the first direction Z, so as to prevent the anti-shake carrier 15 from being separated from the focus carrier 13 during the optical anti-shake process.

It can be understood that although the housing 182 is divided into five portions for introduction, the housing 182 can be a one-piece structure. In addition, in other embodiments, the housing 182 can also be formed by different independent structural members through an assembly process. For example, the first side portion 1822 and the second side portion 1823 of the housing 182 can be fixed to the top portion 1821 of the housing 182 by welding, bonding, or the like.

[0273] As shown in FIG. 33, the housing 182 can include a top portion 1821, a first side portion 1822, a second side portion 1823, a third side portion 1824, and a fourth side portion 1825.
