Description

Technical Field

[0001] The present application relates to the technical field of photographing equipment, and in particular to a motor, a camera module and an electronic device. Background Art

[0002] With the continuous development of portable electronic devices such as mobile phones, users have higher and higher requirements for the camera performance of portable electronic devices. Electronic devices with optical image stabilization and focusing functions are increasingly popular with users. The traditional camera module includes an anti-shake carrier, a focus carrier, a focus drive mechanism and an anti-shake drive mechanism. The focus carrier is located on the inner side of the anti-shake carrier and is movably connected to the anti-shake carrier. The focus drive mechanism is used to drive the focus carrier to move, and the anti-shake drive mechanism is used to drive the anti-shake carrier and the focus carrier to move. The load of the anti-shake drive mechanism is large, and the anti-shake drive mechanism requires a larger size to generate sufficient driving force. Therefore, the size of the traditional camera module is large. In addition, due to the unreasonable setting of the focus drive mechanism and the anti-shake drive mechanism, the electrical connection method of the focus drive mechanism and the anti-shake drive mechanism and the structure of the motor are relatively complicated. Summary of the invention

[0003] The present application provides a motor, a camera module and an electronic device that are both small in size and simple in structure.

[0004] In a first aspect, the present application provides a motor. The motor includes a base, a focus carrier, an anti-shake carrier, a focus magnetic part, a focus coil, a first anti-shake coil, a second anti-shake coil, a first anti-shake magnetic part, a second anti-shake magnetic part and an electrical connector; the focus carrier is movably connected to the base, the anti-shake carrier is located on the inner side of the focus carrier and is movably connected to the focus carrier; the focus magnetic part is fixedly connected to the base, the focus coil is fixedly connected to the focus carrier, and the focus coil is arranged facing the focus magnetic part, and is used to drive the focus carrier and the anti-shake carrier to move in a first direction relative to the base; the first anti-shake coil is fixedly connected to the focus carrier, the first anti-shake magnetic part is fixedly connected to the anti-shake carrier, the first anti-shake coil is located on one side of the first anti-shake magnetic part, and the first anti-shake coil is arranged facing the first anti-shake magnetic part, and is used to drive The dynamic anti-shake carrier moves along a second direction relative to the focus carrier, and the second direction is different from the first direction; the second anti-shake coil is fixedly connected to the focus carrier, and the second anti-shake magnetic part is fixedly connected to the anti-shake carrier. The second anti-shake coil is located on one side of the second anti-shake magnetic part, and the second anti-shake coil is arranged facing the second anti-shake magnetic part, and is used to drive the anti-shake carrier to move along a third direction relative to the focus carrier, and the third direction is different from both the first direction and the second direction; the electrical connecting part includes 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 focus carrier, and is electrically connected to the focus coil, the first anti-shake coil and the second anti-shake coil, and when the focus carrier moves along the first direction relative to the base, the deformation part deforms.

[0005] It can be understood that the anti-shake carrier is located on the inner side of the focus carrier, that is, the motor is a "focus support anti-shake" motor structure, the first anti-shake coil and the first anti-shake magnetic part can cooperate, and the second anti-shake coil and the second anti-shake magnetic part can cooperate to drive the anti-shake carrier to complete the 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 part in this embodiment is small. Then, the first anti-shake coil, the second anti-shake coil, the second anti-shake coil and the second anti-shake magnetic part need to generate a small driving force, the first anti-shake coil, the second anti-shake coil, the second anti-shake coil and the second anti-shake magnetic part are small in size, and the size of the motor is small, which is conducive to the miniaturization of the motor.

[0006] It can be understood that the first anti-shake coil is located on one side of the first anti-shake magnetic component, and the second anti-shake coil is located on one side of the second anti-shake magnetic component. The first anti-shake coil, the second anti-shake coil, the first anti-shake magnetic component and the second anti-shake magnetic component are arranged reasonably, 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 component and the second anti-shake magnetic component and other structural components can be reduced.

[0007] It can be understood that the structure in which the focus 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. In addition, the deformable portion is connected between the first fixed portion and the second fixed portion, and the deformable portion can be deformed during the process in which the second fixed portion moves along the first direction Z with the focus carrier relative to the base, so as to ensure the electrical connection between the focus coil, the first anti-shake coil, and the second anti-shake coil and the base without affecting the movement of the focus carrier.

[0008] In a possible implementation manner, the first anti-shake coil and the first anti-shake magnetic component are arranged along a first direction.

[0009] It can be understood that by arranging the first anti-shake coil and the first anti-shake magnetic component along the first direction, the size of the motor in the XY direction can be reduced.

[0010] In a possible implementation manner, the second anti-shake coil and the second anti-shake magnetic component are arranged along the first direction.

[0011] It can be understood that by arranging the second anti-shake coil and the second anti-shake magnetic component along the first direction, the size of the motor in the XY direction can be reduced.

[0012] In a possible implementation, the first anti-shake magnetic component is a Halbach magnet array.

[0013] It can be understood that the first anti-shake magnetic component is a Halbach magnet array, and the anti-shake driving force roughly along the second direction generated by the cooperation of the first anti-shake coil and the first anti-shake magnetic component is relatively large, which can drive the anti-shake carrier to complete optical image stabilization.

[0014] In a possible implementation, the second anti-shake magnetic component is a Halbach magnet array.

[0015] It can be understood that the second anti-shake magnetic component is a Halbach magnet array, and the anti-shake driving force roughly along the third direction generated by the cooperation of the second anti-shake coil and the second anti-shake magnetic component is relatively large, which can drive the anti-shake carrier to complete optical image stabilization.

[0016] In a possible implementation, the focus coil is located on one side of the focus magnetic component, and a winding plane of the focus coil is parallel to the first direction.

[0017] It is understandable that during the focusing process, the focusing coil can move along the first direction with the focusing carrier. In other words, during the focusing process, the focusing magnetic member and the focusing coil of this embodiment are dynamic coil designs. In this way, it is possible to avoid the focusing magnetic member from causing magnetic interference to the first anti-shake magnetic member, the second anti-shake magnetic member or other magnetic structural members. In addition, the winding plane of the focusing coil can be parallel to the first direction, which is beneficial to reducing the size of the motor in the XY direction.

[0018] In a possible implementation manner, the deformation portion is provided with a through hole.

[0019] It can be understood that, compared with the electrical connector with a deformation portion without a through hole, the K value of the electrical connector with a deformation portion with a through hole is reduced, wherein the K value is the elastic coefficient. Then, when the deformation portion produces the same deformation amount, the elastic force of the electrical connector of this 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 focus carrier and the anti-shake carrier, the elastic force of the electrical connector is smaller, and the elastic force of the electrical connector has less influence on the focusing process, which is beneficial to improve the stability of the movement of the motor. In addition, the deformation of the electrical connector is caused by the movement of the focus carrier and the anti-shake carrier along the first direction Z, the deformation of the electrical connector is smaller, the driving force required for the deformation is also smaller, and the driving force required to be provided by the focusing magnetic part and the focusing coil is also smaller, which is beneficial to reduce the volume of the focusing magnetic part and the focusing coil.

[0020] In a possible implementation manner, the through hole is a strip-shaped hole, and the through hole extends along the length extension direction of the deformation portion.

[0021] It can be understood that, compared with the solution in which no through hole is set in the deformation part, the through hole of the deformation part in this embodiment makes the deformation part forked, and the width of the deformation part along the second direction or the third direction is smaller. The K value of the electrical connector in this embodiment can be reduced, and the elastic force of the electrical connector can be reduced.

[0022] In one possible implementation, in the thickness direction of the deformation part, the deformation part includes a plurality of layers of deformation sub-parts, the first end of each layer of deformation sub-parts is fixedly connected to the first fixed part, the second end of each layer of deformation sub-parts is fixedly connected to the second fixed part, and the deformation sub-parts of two adjacent layers are spaced apart to form a hollow area.

[0023] It can be understood that, compared with a solution in which the deformation part is not arranged in layers, the deformation part arranged in layers in this embodiment makes the thickness of the deformation part along the first direction smaller, and the K value of the electrical connector of this embodiment can be reduced.

[0024] It can be understood that, compared with an electrical connector without a layered deformation portion, the K value of the electrical connector with a layered deformation portion of the present 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 focus carrier and the anti-shake carrier, the elastic force of the electrical connector is relatively small, and the elastic force of the electrical connector has little effect on the focusing process, which is beneficial to improving the stability of the motor movement. In addition, the deformation of the electrical connector is caused by the movement of the focus carrier and the anti-shake carrier along the first direction, the deformation of the electrical connector is relatively small, the driving force required for the deformation is also relatively small, and the driving force required to be provided by the focus magnetic part and the focus coil is also relatively small, which is beneficial to reducing the volume of the focus magnetic part and the focus coil.

[0025] In a possible implementation manner, at least a portion of the deformation portion is in a spiral shape, a zigzag shape, or a curved shape.

[0026] It is understandable that the deformation portion of the present embodiment can be extended. Compared with the solution in which the deformation portion is not extended, the K value of the electrical connector of the present embodiment can be reduced. In this way, in the process that the second fixed portion of the electrical connector moves along the first direction with the focus carrier and the anti-shake carrier, the elastic force of the electrical connector is small, and the elastic force of the electrical connector has little effect on the focusing process, which is beneficial to improve the stability of the motor movement. In addition, the deformation of the electrical connector is caused by the movement of the focus carrier and the anti-shake carrier along the first direction, the deformation of the electrical connector is small, the driving force required for the deformation is also small, and the driving force required to be provided by the focus magnetic part and the focus coil is also small, which is beneficial to reduce the volume of the focus magnetic part and the focus coil.

[0027] In one possible implementation, the focusing carrier includes a base 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 base plate and are fixedly connected to the base plate; the focusing coil is fixedly connected to the first side plate, and the first anti-shake coil and the second anti-shake coil are fixedly connected to the base plate; the second fixing part 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 a side of the base close to the base and is fixedly connected to the base plate.

[0028] It can be understood that the structure in which the focus 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.

[0029] In one possible implementation, the motor includes a driving chip, which is located on a side of the first part close to the focusing carrier, and the driving chip is fixedly connected and electrically connected to the first part; the focusing coil is electrically connected to the driving chip through the first part of the second fixed part of the electrical connector; 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 fixed part of the electrical connector.

[0030] It is understandable that, compared with the solution where the driving chip is located on the side of the electrical connector away from the focusing carrier, the first portion of the second fixing portion of the electrical connector in this embodiment does not need to be bent at a large angle toward the second portion.

[0031] It is understandable that the driver chip can control the current of the focus coil (e.g., whether current is flowing or the magnitude of the current when energized) through the first part of the second fixed portion of the electrical connector to control the focusing process of the motor. The driver chip can control the current of the first anti-shake coil and the second anti-shake coil (e.g., whether current is flowing or the magnitude of the current when energized) through the second part of the second fixed portion of the electrical connector to control the optical anti-shake process of the motor.

[0032] In one possible implementation, the motor also includes a wiring, which is embedded in the focusing carrier, and the wiring forms a current loop with the first part of the second fixed part of the electrical connector, the focusing coil, and the driving chip, and the wiring forms a current loop with the second part of the second fixed part of the electrical connector, the first anti-shake coil, and the driving chip, and the wiring forms a current loop with the second part of the second fixed part of the electrical connector, the second anti-shake coil, and the driving chip.

[0033] It is understandable that the driver chip can control the current of the focus coil (e.g., whether current is flowing or the magnitude of the current when energized) through the first part of the wiring and the second fixed part of the electrical connector to control the focusing process of the motor. The driver chip can control the current of the first anti-shake coil and the second anti-shake coil (e.g., whether current is flowing or the magnitude of the current when energized) through the second part of the wiring and the second fixed part of the electrical connector to control the optical anti-shake process of the motor.

[0034] In a possible implementation, the second portion of the second fixing part is provided with a pin end; the routing includes a bending portion, and the bending portion and the pin end are arranged along a first direction and fixedly connected to the pin end.

[0035] It can be understood that the bent portion of the wiring makes the connection process between the wiring and the electrical connector simpler.

[0036] In a possible implementation, the motor includes a first guide member, and the focus carrier is movably connected to the base via the first guide member.

[0037] It can be understood that the first guide member can reduce the friction resistance during the relative movement between the focus carrier and the base, reduce the power required to be provided by the focus magnetic member and the focus coil, and thus reduce the size of the focus magnetic member and the focus coil.

[0038] In one possible implementation, the motor includes a focusing magnetic element, which is fixed to the focusing carrier and arranged facing the focusing magnetic element. The magnetic force between the focusing magnetic element and the focusing magnetic element maintains contact between the base, the first guide element and the focusing carrier.

[0039] It is understandable that the magnetic force between the focus magnetic attraction member and the focus magnetic member keeps the base, the first guide member and the focus carrier in contact. During the focusing process of the motor, the focus carrier is not prone to tipping over due to movement.

[0040] In a possible implementation, the focusing magnetic attraction component and the focusing carrier are an integrally formed structure.

[0041] It is understandable that the focus magnetic element and the focus carrier are an integrated structure, which makes the assembly tolerance of the focus magnetic element smaller, thereby reducing the fluctuation of the magnetic force between the focus magnetic element and the focus magnetic element, and improving the movement stability of the motor. Compared with the structure of other focus magnetic solutions, the structure of the focus magnetic solution of this embodiment is simpler.

[0042] 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 arranged opposite to the first groove, and at least part of the first guide is located in the first groove and at least part of the first guide is located in the second groove.

[0043] It can be understood that the first groove and the second groove can limit the first guide member to prevent the first guide member from being separated from between the base and the focusing carrier.

[0044] In a possible implementation, the motor includes a second guide member, and the anti-shake carrier is movably connected to the focus carrier via the second guide member.

[0045] It can be understood that the second guide member can reduce the friction resistance during the relative movement between the focusing carrier and the anti-shake carrier, reduce the power required to be provided by the first anti-shake coil and the first anti-shake magnetic component, and reduce the power required to be provided by the second anti-shake coil and the second anti-shake magnetic component, thereby reducing the size of the first anti-shake coil, the first anti-shake magnetic component, the second anti-shake coil and the second anti-shake magnetic component.

[0046] 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 arranged opposite to the third groove, and at least part of the second guide is located in the third groove and at least part of the second guide is located in the fourth groove.

[0047] It can be understood that the third groove and the fourth groove can limit the second guide member, thereby preventing the second guide member from being separated from between the focusing carrier and the anti-shake carrier.

[0048] In a possible implementation, the second guide member is a single ball or a group of balls.

[0049] It is understandable that the active connection between the focus carrier and the anti-shake carrier is achieved through the second guide member, which can reduce the friction resistance between the second guide member and the anti-shake carrier while ensuring sufficient supporting force, and can reduce the demand for the driving force during the movement of the anti-shake carrier, that is, it is conducive to reducing the size of the first anti-shake coil and / or the first anti-shake magnetic member, the second anti-shake coil and / or the second anti-shake magnetic member, and is conducive to the miniaturization of the motor. For example, compared with the diameter of the traditional large ball, the diameter of each ball in the second guide member of this embodiment is smaller, which is also conducive to shortening the interval between the anti-shake carrier and the base, and is conducive to the thinning of the motor. In addition, the second guide member can provide multi-point support for the anti-shake carrier, which is conducive to dispersing stress, preventing the ball in the second guide member from being deformed when being hit due to excessive concentration of force in a single direction, and can improve the reliability of the second guide member supporting the anti-shake carrier and other structural parts.

[0050] In one possible implementation, the motor includes an anti-shake magnetic component, which is fixed to the focus carrier and arranged facing the first anti-shake magnetic component and the second anti-shake magnetic component. The magnetic force between the anti-shake magnetic component and the first anti-shake magnetic component and the second anti-shake magnetic component maintains contact between the anti-shake carrier, the second guide component and the focus carrier.

[0051] It can be understood that the magnetic force between the first anti-shake magnetic component and the anti-shake magnetic suction component, and the magnetic force between the second anti-shake magnetic component and the anti-shake magnetic suction component enable the anti-shake carrier to be subjected to the anti-shake magnetic force, so that the anti-shake carrier, the second guide component and the focus carrier maintain contact, ensure the connection stability between the anti-shake carrier, the second guide component and the focus carrier, and avoid the anti-shake carrier from escaping from the focus carrier. In addition, compared with the structures of other anti-shake magnetic suction solutions, the structure of the anti-shake magnetic suction solution of this embodiment is simpler.

[0052] In a possible implementation, the motor further includes a reed, one end of which is fixedly connected to the focus carrier, and the other end of which is fixedly connected to the anti-shake carrier.

[0053] It can be understood that, since the reed is connected between the anti-shake carrier and the focus carrier, the movement of the anti-shake carrier causes the reed to undergo elastic deformation and have an elastic force, so that the anti-shake carrier is reset and the anti-shake carrier can return to a position with a displacement of dx. The reed can also provide an anti-torsion force to the anti-shake carrier, hindering the rotation of the anti-shake carrier. In addition, in this embodiment, the first anti-shake coil is located on one side of the first anti-shake magnetic component, and the second anti-shake coil is located on one side of the second anti-shake magnetic component, which can reduce the risk of short circuit between the first anti-shake coil, the second anti-shake coil and the reed and other structural components, thereby improving the reliability of the motor.

[0054] In a second aspect, the present application provides a camera module, which includes a lens and the above-mentioned motor, wherein the lens is fixed to an anti-shake carrier.

[0055] It is understandable that the camera module is small in size and simple in structure.

[0056] In a third aspect, the present application provides an electronic device, which includes a housing and the above-mentioned camera module, wherein the camera module is disposed in the housing.

[0057] It is understandable that the electronic device can have both a smaller size and a simpler structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0092] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application.

[0093] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "install", "connect", "connect", and "connect" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be an electrical connection or a mechanical connection. Among them, "fixed connection" means that the relative position relationship after connection remains unchanged. "Active connection" means that the two components are connected to each other and can move relative to each other after connection. In addition, the two components are obtained by an integrated molding process. The integrated structure means that in the process of forming one of the two components, the component is connected to the other component, and the two components do not need to be connected together by reprocessing (such as bonding, welding, snap connection, screw connection). The relative arrangement of component A and component B can be that component A is projected along the target direction to obtain projection C, and component B is projected along the target direction to obtain projection D, and projection C and projection D can overlap at least in part. In some embodiments, the majority of overlap can be any of the following: projection C is completely located in projection D. Or, projection D is completely located in projection C. Alternatively, projection C and projection D intersect each other, and the intersection area of ​​projection C and projection D accounts for a ratio of projection C or projection D that is greater than 50%.

[0094] The directional terms mentioned in the embodiments of the present application, such as "top", "bottom", "inside", "outside", etc., are only references to the directions of the drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0095] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally indicates that the objects associated before and after are in an "or" relationship. "Multiple" means at least two.

[0096] In addition, in the embodiments of the present application, the limitations of the relative position relationship mentioned, such as parallel, vertical, etc. These limitations are all for the current state of the art, rather than absolutely strict limitations, and a small amount of deviation is allowed, and it is possible to be approximately parallel, approximately vertical, etc. For example, A and B are parallel, which means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. For example, A and B are perpendicular, which means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0097] Figure 1 It is a structural diagram of an electronic device 1000 provided in an embodiment of the present application.

[0098] like Figure 1 As shown, the electronic device 1000 can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, a vehicle-mounted device, a wearable device, an augmented reality (AR) glasses, an AR helmet, a virtual reality (VR) glasses or a VR helmet, etc., which have a camera module. The electronic device 1000 of the embodiment of the present application is described by taking a mobile phone as an example.

[0099] For ease of description, the width direction of the electronic device 1000 is defined as the X-axis. The length direction of the electronic device 1000 is the Y-axis. The thickness direction of the electronic device 1000 is the Z-axis. It is understandable that the coordinate system setting of the electronic device 1000 can be flexibly set according to specific actual needs. In this embodiment, the Z-axis direction is defined as the first direction. The X-axis direction is the second direction. The second direction may be different from the first direction. The Y-axis direction is the third direction. The third direction may be different from both the first direction and the second direction. In other embodiments, the first direction, the second direction and the third direction may be any direction of the coordinate system, and it is only necessary to ensure that the first direction, the second direction and the third direction are different from each other. Specifically, this embodiment is not limited.

[0100] Figure 2 yes Figure 1 The illustrated electronic device 1000 is a partial cross-sectional schematic diagram of an embodiment taken along line AA.

[0101] like Figure 1 and Figure 2As shown, in some embodiments, the electronic device 1000 may include a camera module 100, a housing 200, and a screen 300. The camera module 100 may be a rear camera module 100 or a front camera module 100. It is understood that Figure 1 , Figure 2 The following figures and the related drawings only schematically illustrate some components of the electronic device 1000, and the actual shapes, sizes, positions and structures of these components are not limited to the following. Figure 1 , Figure 2 In addition, when the electronic device 1000 is a device of some other form, the electronic device 1000 may not include the screen 300 .

[0102] like Figure 1 and Figure 2 As shown, in some embodiments, the screen 300 is mounted on the housing 200, and together with the housing 200, encloses the 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. Among them, the screen 300 can be a flat screen or a curved screen.

[0103] For example, the camera module 100 may be located inside 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 shape of the light-transmitting portion 201. Figure 1 The circular shape shown may also be an elliptical or irregular shape. Light from outside the electronic device 1000 may enter the interior of the electronic device 1000 through the light-transmitting portion 201. The camera module 100 may collect light entering the interior of the electronic device 1000. The light-transmitting portion 201 may be a light-transmitting hole or a transparent portion in the housing 200. The specific structure of the light-transmitting portion 201 is not specifically limited in this application.

[0104] Figure 3 yes Figure 1 The camera module 100 shown is a partial structural decomposition schematic diagram in one embodiment.

[0105] like Figure 2 and Figure 3 As shown, exemplarily, the camera module 100 includes a motor 1 and a lens 2. It is understandable that Figure 2 and Figure 3 Only some components of the camera module 100 are schematically shown, and the actual shapes, sizes, positions and structures of these components are not subject to the present invention. Figure 2 and Figure 3 The camera module 100 may also include more or fewer structures. For example, the camera module 100 may also include a variable aperture (not shown in the drawings).

[0106] For example, the lens 2 can be mounted on the motor 1. The motor 1 can also control the lens 2 to move along the first direction Z to achieve focusing (Auto Focus, AF). In other words, the camera module 100 of the present application can control the lens 2 to move along the first direction Z through the motor 1 to achieve focusing 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 perpendicular to the first direction Z (that is, the XY plane) to achieve optical image stabilization (OIS). In this way, when the camera module 100 collects ambient light, if the electronic device 1000 generates jitter on the XY plane due to external force, the motor 1 can be used to control the movement of the lens 2 on the XY plane to offset the jitter stroke of the lens 2 on the XY plane, so as to avoid reducing the position offset of the lens 2 caused by the jitter. In other words, the camera module 100 of the present application can control the movement of the lens 2 on the XY plane through the motor 1 to achieve optical image stabilization of the camera module 100 and improve the imaging quality of the camera module 100.

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

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

[0110] Figure 4 yes Figure 3 The motor 1 shown is a schematic diagram of a partial structural explosion in one embodiment.

[0111] like Figure 4 As shown, exemplarily, the motor 1 includes a base 11, a first guide 121, a second guide 122, a focus carrier 13, a focus drive mechanism 14, an anti-shake carrier 15, an anti-shake drive mechanism 16 and an electrical connection 17. It can be understood that Figure 3 and Figure 4 Only some components of the motor 1 are schematically shown, and the actual shape, size, position and structure of these components may not be affected by the present invention. Figure 3 and Figure 4 Limited by.

[0112] Exemplarily, the focus drive mechanism 14 may include a focus magnetic member 141 and a focus coil 142. In other embodiments, the focus drive mechanism 14 may include more or fewer structures, for example, the focus drive mechanism 14 may also include a focus magnetic member (not shown in the drawings).

[0113] It is understandable that the number of focusing magnetic members 141 may not be limited to Figure 4 As shown in FIG. 1 , the number of focus coils 142 may be limited to Figure 4 In other embodiments, there may be multiple focus magnetic members 141, multiple focus coils 142, and multiple focus magnetic members 141 and multiple focus coils 142 may be arranged in a one-to-one correspondence.

[0114] In other implementations, the focus driving mechanism 14 may also adopt other forms of driving structures, which are not specifically limited in this application.

[0115] Exemplarily, the anti-shake drive mechanism 16 may include a first anti-shake coil 161, a second anti-shake coil 162, a first anti-shake magnetic component 163 and a second anti-shake magnetic component 164. Exemplarily, the first anti-shake coil 161 and the first anti-shake magnetic component 163 may be arranged correspondingly to form a set of drive mechanisms. The second anti-shake coil 162 and the second anti-shake magnetic component 164 may be arranged correspondingly to form a set of drive mechanisms. In other embodiments, the anti-shake drive mechanism 16 may also include more or fewer structures. For example, the anti-shake drive mechanism 16 may also include an anti-shake magnetic conductive component (not shown in the drawings).

[0116] It is understandable that the number of the first anti-shake coils 161 may not be limited to Figure 4 As shown in FIG. 1 , the number of the first anti-shake magnetic member 163 may not be limited to Figure 4 In other implementations, there may be multiple first anti-shake coils 161, multiple first anti-shake magnetic components 163, and multiple first anti-shake coils 161 and first anti-shake magnetic components 163 may be arranged in one-to-one correspondence.

[0117] It is understandable that the number of the second anti-shake coils 162 may not be limited to Figure 4 As shown in FIG. 1 , the number of the second anti-shake magnetic member 164 may not be limited to Figure 4 In other implementations, there may be multiple second anti-shake coils 162, multiple second anti-shake magnetic components 164, and multiple second anti-shake coils 162 and second anti-shake magnetic components 164 may be arranged in one-to-one correspondence.

[0118] In other implementations, the anti-shake driving mechanism 16 may also adopt other forms of driving structures, which are not specifically limited in this application.

[0119] It can be understood that the number of the first guide members 121 and the number of the second guide members 122 can both be plural. For example, in this embodiment, two first guide members 121 and four second guide members 122 are used as an example for illustration.

[0120] Exemplarily, the motor 1 may further include a pressing piece 181 and a housing 182. In other embodiments, the motor 1 may also not include the pressing piece 181 and / or the housing 182.

[0121] Figure 5 yes Figure 4 The shown diagram is a partial structural diagram of the base 11 in one embodiment.

[0122] like Figure 5 As shown, illustratively, the base 11 includes a bottom 111 and a side 112. The side 112 can be located on one side of the bottom 111 and fixedly connected to the bottom 111. In other embodiments, the base 11 can also adopt other structures. It can be understood that although the base 11 is divided into two parts for introduction in this embodiment, it does not affect the fact that the base 11 can be an integrally molded structure, that is, the bottom 111 and the side 112 can be integrally molded. In other embodiments, the base 11 can also be formed by different independent structural parts through an assembly process. The side 112 of the base 11 can be an independent structural part, and is fixedly connected to the bottom 111 by gluing, welding, etc.

[0123] For example, the side portion 112 of the base 11 may be provided with a first groove 1121. In one embodiment, the length extension direction of the first groove 1121 may be the first direction Z. The number of the first grooves 1121 may be the same as the number of the first guide members 121 (see Figure 4 ), for example, the number of the first grooves 1121 may be two. The two first grooves 1121 may be arranged at intervals.

[0124] For example, the side portion 112 of the base 11 may be provided with a first mounting groove 1122, and the first mounting groove 1122 may be located between the two first grooves 1121. In other embodiments, the position of the first mounting groove 1122 is not specifically limited.

[0125] Figure 6 yes Figure 3 The motor 1 shown in FIG. 1 is a schematic diagram of a partial structure of an embodiment of the present invention. Figure 1 .

[0126] like Figure 6As shown, the first guide member 121 may be fixedly connected to the base 11. Exemplarily, at least a portion of the first guide member 121 may be located in the first groove 1121.

[0127] For example, the first guide member 121 may be a sliding shaft structure, and in other embodiments, the first guide member 121 may also be a ball bearing or other structures, which are not specifically limited in the present application.

[0128] Exemplarily, the focusing magnetic member 141 may be mounted on the base 11. In one embodiment, at least a portion of the focusing magnetic member 141 may be located in the first mounting groove 1122. The focusing magnetic member 141 may be a Halbach magnet array. It is understood that the Halbach magnet array can generate a higher intensity magnetic field, and the focusing magnetic member 141 can have a greater magnetic force.

[0129] In other embodiments, the focusing magnetic member 141 may be other types of magnets or magnetic components. For example, the focusing magnetic member 141 may adopt a dual magnet solution, that is, it may be composed of two magnets, which are arranged in a first direction Z and have opposite polarities. It is understood that the polarity direction may be the direction from the North Pole (N) to the South Pole (S), or the direction from the South Pole (S) to the North Pole (N).

[0130] Figure 7 yes Figure 4 The focusing carrier 13 shown is a schematic diagram of a partial structural decomposition in one embodiment. Figure 8 yes Figure 7 The focusing carrier 13 is shown as a schematic structural diagram at another angle.

[0131] like Figure 7 and Figure 8 As shown, exemplarily, the focusing carrier 13 includes a bottom plate 131, a first side plate 132, a second side plate 133, a first protrusion 134, and a second protrusion 135. The first side plate 132 and the second side plate 133 may be located on the same side of the bottom plate 131 and fixedly connected to the bottom plate 131. The first protrusion 134 and the second protrusion 135 may be located on the same side of the bottom plate 131 and fixedly connected to the bottom plate 131. The first protrusion 134 and the second protrusion 135 may be arranged at intervals. In other embodiments, the focusing carrier 13 may also adopt other structures.

[0132] It is understandable 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 parts through an assembly process. For example, the first side plate 132 and the second side plate 133 of the focusing carrier 13 can be two independent structural parts fixed to the bottom plate 131 of the focusing carrier 13 by welding, bonding, etc.

[0133] Exemplarily, the first side plate 132 of the focusing carrier 13 may be provided with a second groove 1321. In one embodiment, the second groove 1321 may extend along the first direction Z. The number of the second grooves 1321 may be the same as that of the first guide member 121 (see Figure 4 ), for example, the number of the second grooves 1321 can be two, and the two second grooves 1321 can be arranged at intervals.

[0134] For example, the bottom plate 131 of the focus carrier 13 may be provided with third grooves 1311. In one embodiment, the number of the third grooves 1311 may be the same as the number of the second guide members 122 (see Figure 4 ), for example, the number of the third grooves 1311 can be four.

[0135] Fig. 9 yes Figure 3 The motor 1 shown in FIG. 1 is a schematic diagram of a partial structure of an embodiment of the present invention. Figure 2 .

[0136] like Fig. 9 As shown, the focus coil 142 may be fixedly connected to the focus carrier 13. For example, the focus coil 142 may be fixedly connected to the first side plate 132.

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

[0138] Exemplarily, the second anti-shake coil 162 may be fixedly connected to the focus carrier 13. The second anti-shake coil 162 may be located on a side of the bottom plate 131 facing the first side plate 132 and the second side plate 133, and may be fixedly connected to the bottom plate 131.

[0139] Exemplarily, at least a portion of the second guide member 122 may be located in the third groove 1311. It is understood that the second guide member 122 may be a ball group, each ball group may include a plurality of balls, the number of balls may be three, ten, etc., which is not specifically limited in this application. In other embodiments, the second guide member 122 may also be a single ball, a sliding shaft or other structures. This is not specifically limited in this application.

[0140] Fig.10 yes Figure 3 The motor 1 shown in FIG. 1 is a schematic diagram of a partial structure of an embodiment of the present invention. Figure 3 .

[0141] like Fig.10 As shown, the focusing carrier 13 can be movably connected to 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 arranged relative to each other. Among them, at least part of the first guide 121 can be located in the first groove 1121, and at least part of it can be located in the second groove 1321.

[0142] It is understandable that the first guide member 121 can reduce the friction resistance when the focus carrier 13 and the base 11 move relative to each other, reduce the power provided by the focus drive mechanism 14, and thus reduce the size of the focus drive mechanism 14. The first groove 1121 and the second groove 1321 can limit the first guide member 121, preventing the first guide member 121 from being separated from between the base 11 and the focus carrier 13.

[0143] In other implementations, the focusing carrier 13 may also be movably connected to the base 11 in other ways. This application does not limit this in detail.

[0144] Fig.11 yes Fig.10 The shown diagram is a partial cross-sectional view of the motor 1 in one embodiment at line BB.

[0145] See also Fig.10 and Fig.11 , and combined with Figure 2 As shown, illustratively, the focus magnetic member 141 can be fixedly connected to the base 11, the focus coil 142 can be fixedly connected to the focus carrier 13, the focus coil 142 can be located on one side of the focus magnetic member 141, the focus coil 142 can be arranged facing the focus magnetic member 141, and the winding plane of the focus coil 142 can be parallel to the first direction Z. It can be understood that the winding plane of the focus coil 142 can be parallel to the first direction, which is conducive to reducing the size of the motor 1 in the XY direction.

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

[0147] Fig.12 yes Figure 3 The partial structure of the motor 1 in one embodiment is shown as follows: Figure 4 .

[0148] like Fig.11 and Fig.12 As shown, the motor 1 further includes a focus magnetic attraction member 191. Exemplarily, the focus magnetic attraction member 191 may be made of a material that can generate magnetic force with a magnet or other magnetic components, such as a ferromagnetic material.

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

[0150] Exemplarily, the focusing magnetic element 191 and the focusing carrier 13 may be an integrally formed structure. It is understandable that the focusing magnetic element 191 is integrally formed with the focusing carrier 13, which can reduce the assembly tolerance of the focusing magnetic element and reduce the fluctuation of the magnetic force.

[0151] In other implementations, the focusing magnetic element 191 may also be fixedly connected to the focusing carrier 13 by welding, gluing, or the like.

[0152] like Fig.11 As shown, exemplarily, the focusing magnetic member 191 can be arranged facing the focusing magnetic member 141. The magnetic force between the focusing magnetic member 191 and the focusing magnetic member 141 enables the base 11, the first guide member 121 and the focusing carrier 13 to maintain contact. It can be understood that in the process of focusing the focusing carrier 13 along the first direction Z, the magnetic force between the focusing magnetic member 191 and the focusing magnetic member 141 enables the base 11, the first guide member 121 and the focusing carrier 13 to maintain contact, which can prevent the focusing carrier 13 from tilting or flipping, thereby improving the stability of the movement of the motor 1.

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

[0154] Exemplarily, during the movement of the focus carrier 13 and the anti-shake carrier 15 relative to the base 11 along the first direction Z, the magnetic force between the focus magnetic member 141 and the focus magnetic member 191 in the X-axis direction may satisfy: -550N (Newton) ≤ Fx ≤ -520N, wherein Fx may represent the component force of the magnetic force of the focus magnetic member 191 in the X-axis direction received by the focus magnetic member 141 when the focus carrier 13 and the anti-shake carrier 15 move relative to the base 11 along the Z-axis direction, and a negative value of Fx means that the component force of the magnetic force of the focus magnetic member 191 received by the focus magnetic member 141 in the X-axis direction is oriented in the negative direction of the X-axis. For example, Fx may be equal to -544N, -538N, -532N, or -528N, 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 member 191 in the Y-axis direction may satisfy: 0≤Fy≤1N, wherein Fy may represent the component force of the magnetic force of the focusing magnetic member 191 in the Y-axis direction received by the focusing magnetic member 141 when the focusing carrier 13 and the anti-shake carrier 15 move relative to the base 11 along the Z-axis direction, and a positive value of Fy means that the component force of the magnetic force of the focusing magnetic member 191 received by the focusing magnetic member 141 in the Y-axis direction is oriented in the positive direction of the Y-axis. For example, Fy may 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 suction member 191 in the Z-axis direction may satisfy: -6N≤Fz≤6N, wherein Fz may represent the component force in the Z-axis direction of the magnetic force of the focusing magnetic suction member 191 received by the focusing magnetic member 141 when the focusing carrier 13 and the anti-shake carrier 15 move relative to the base 11 along the Z-axis direction, and a negative value of Fz means that the component force in the Z-axis direction of the magnetic force of the focusing magnetic suction member 191 received by the focusing magnetic member 141 is oriented in the negative direction of the Z-axis. A positive value of Fz means that the component force in the Z-axis direction of the magnetic force of the focusing magnetic suction member 191 received by the focusing magnetic member 141 is oriented in the positive direction of the Z-axis. For example, Fz may be equal to -5N, -4N, -1N, 3N or 5N, etc.

[0157] For example, the magnetic force between the focus magnetic member 141 and the focus magnetic member 191 is relatively large, and the focus magnetic member 141 can be affected by the magnetic force of the focus magnetic member 191, and the focus carrier 13 and the anti-shake carrier 15 can return to the position where the displacement dz is 0 after the focus is completed. In addition, the base 11, the first guide member 121 and the focus carrier 13 can maintain contact, thereby preventing the focus carrier 13 from tilting or flipping, thereby improving the stability of the movement of the motor 1.

[0158] In other embodiments, dx, Fx, Fy and Fz may satisfy other ranges. Specifically, the present application is not limited thereto.

[0159] Exemplarily, when the focus coil 142 is energized, a focus driving force may be generated between the focus coil 142 and the focus magnetic member 141 , thereby driving the focus carrier 13 and the anti-shake carrier 15 to move along the first direction Z relative to the base 11 .

[0160] Exemplarily, the driving force generated between the focus magnetic part 141 and the focus coil 142 in the X-axis direction may satisfy: -70N≤Fx≤70N, wherein Fx may represent the component force in the X-axis direction of the focus driving force generated between the focus coil 142 and the focus magnetic part 141 on the focus carrier 13 when the focus carrier 13 and the anti-shake carrier 15 move along the Z-axis direction relative to the base 11, and a positive value of Fx means that the component force in the X-axis direction of the focus driving force generated between the focus coil 142 and the focus magnetic part 141 on the focus carrier 13 is oriented in the positive direction of the X-axis. A negative value of Fx means that the component force in the X-axis direction of the focus driving force generated between the focus coil 142 and the focus magnetic part 141 on the focus carrier 13 is oriented in the negative direction of the X-axis. For example, Fx may be equal to -61N, -33N, -17N, 17N, 48N or 61N, etc.

[0161] Exemplarily, the driving force generated between the focus magnetic part 141 and the focus coil 142 in the Y-axis direction may satisfy: -1N≤Fy≤1N, wherein Fy may represent the component force in the Y-axis direction of the focus driving force generated between the focus coil 142 and the focus magnetic part 141 on the focus carrier 13 when the focus carrier 13 and the anti-shake carrier 15 move relative to the base 11 along the Z-axis direction, and a negative value of Fy means that the component force in the Y-axis direction of the focus driving force generated between the focus coil 142 and the focus magnetic part 141 on the focus carrier 13 is oriented in the negative direction of the Y-axis. A positive value of Fy means that the component force in the Y-axis direction of the focus driving force generated between the focus coil 142 and the focus magnetic part 141 on the focus carrier 13 is oriented in the positive direction of the Y-axis. For example, Fy may be equal to -0.7N, -0.5N, -0.1N, 0.1N, 0.3N or 0.6N, etc.

[0162] Exemplarily, the driving force generated between the focus magnetic part 141 and the focus coil 142 in the Z-axis direction may satisfy: 100N≤Fz≤150N, wherein Fz may represent the component force in the Z-axis direction of the focus driving force generated between the focus coil 142 and the focus magnetic part 141 on the focus carrier 13 when the focus carrier 13 and the anti-shake carrier 15 move in the Z-axis direction relative to the base 11, and a positive value of Fz means that the component force in the Z-axis direction of the focus driving force generated between the focus coil 142 and the focus magnetic part 141 on the focus carrier 13 is oriented in the positive direction of the Z-axis. For example, Fz may be equal to 112N, 122N, 129N, 135N or 137N, etc.

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

[0164] In other embodiments, Fx, Fy and Fz may satisfy other ranges. Specifically, the present application is not limited thereto.

[0165] Fig.13 yes Figure 4 The illustrated diagram is a partial structural diagram of an anti-shake carrier 15 in one implementation manner. Fig.14 yes Fig.13 The structure diagram of the anti-shake carrier 15 shown is shown at another angle.

[0166] like Fig.13 and Fig.14 As shown, illustratively, the anti-shake carrier 15 may be substantially quadrilateral.

[0167] For example, the anti-shake carrier 15 may also be provided with a second mounting slot 151. The second mounting slot 151 may be located on one side of the anti-shake carrier 15. In one embodiment, the number of the second mounting slots 151 may be the same as the number of the first anti-shake magnetic member 163 (see Figure 4 ), the second anti-shake magnetic element 164 (see Figure 4 ), the number of the second mounting grooves 151 can be two, and the two second mounting grooves 151 can be respectively located on two sides of the anti-shake carrier 15.

[0168] For example, the anti-shake carrier 15 may be provided with a fourth groove 152. The fourth groove 152 and the second mounting groove 151 may be located on the same side of the anti-shake carrier 15. In one embodiment, the number of the fourth grooves 152 may match the number of the second guide members 122, the number of the fourth grooves 152 may be four, and the four fourth grooves 152 may be located at the four corners of the anti-shake carrier 15, respectively.

[0169] Fig.15 yes Figure 3 The motor 1 shown in FIG. 1 is a schematic diagram of a partial structure of an embodiment of the present invention. Figure 5 .

[0170] like Fig.15 As shown, the first anti-shake magnetic component 163 can be fixedly connected to the anti-shake carrier 15. Exemplarily, the first anti-shake magnetic component 163 can be located in the second mounting slot 151. Among them, the first anti-shake magnetic component 163 can be a Halbach magnet array. In other embodiments, the first anti-shake magnetic component 163 can be other types of magnets or magnetic components. For example, the first anti-shake magnetic component 163 can adopt a dual magnet solution, that is, it is composed of two magnets, and the two magnets are arranged in the second direction X and have opposite polarities.

[0171] like Fig.15 As shown, the second anti-shake magnetic component 164 can be fixedly connected to the anti-shake carrier 15. Exemplarily, the second anti-shake magnetic component 164 can be located in the second mounting slot 151. Among them, the second anti-shake magnetic component 164 can be a Halbach magnet array. In other embodiments, the second anti-shake magnetic component 164 can be other types of magnets or magnetic components. For example, the second anti-shake magnetic component 164 can adopt a dual magnet solution, that is, it is composed of two magnets, and the two magnets are arranged in the third direction Y and have opposite polarities.

[0172] Fig.16 yes Figure 3 The motor 1 shown in FIG. 1 is a schematic diagram of a partial structure of an embodiment of the present invention. Figure 6 . Fig.17 yes Fig.16 The shown diagram is a partial cross-sectional view of an embodiment of the motor 1 at line CC.

[0173] like Fig.16 and Fig.17 As shown, the anti-shake carrier 15 can be located inside the focus carrier 13 and movably connected to the focus carrier 13. In other words, the motor 1 of the present application is a "focus support anti-shake" motor structure. Figure 2 ) can be located on the inner side of the anti-shake carrier 15 and fixedly connected to the anti-shake carrier 15.

[0174] Exemplarily, the anti-shake carrier 15 may be movably connected to the focus carrier 13 via the second guide 122. The fourth groove 152 of the anti-shake carrier 15 may be arranged opposite to the third groove 1311 of the focus carrier 13. At least a portion of the second guide 122 may be located in the third groove 1311, and at least a portion of the second guide 122 may be located in the fourth groove 152.

[0175] It is understandable that the second guide member 122 can reduce the friction resistance when the focus carrier 13 and the anti-shake carrier 15 move relative to each other, reduce the power provided by the anti-shake drive mechanism 16, and thus reduce the size of the anti-shake drive mechanism 16. The third groove 1311 and the fourth groove 152 can limit the second guide member 122, preventing the second guide member 122 from being separated from between the focus carrier 13 and the anti-shake carrier 15.

[0176] It can be understood that the second guide member 122 is a group of balls, and the second guide member 122 is used to realize the movable connection between the focus carrier 13 and the anti-shake carrier 15, which can reduce the friction resistance between the second guide member 122 and the anti-shake carrier while ensuring sufficient supporting force, and can reduce the demand for the driving force during the movement of the anti-shake carrier, that is, it is conducive to reducing 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, which is conducive to realizing the miniaturization of the motor 1. For example, compared with the diameter of the traditional large ball, the diameter of each ball in the second guide member 122 of this embodiment is smaller, which is also conducive to shortening the interval between the anti-shake carrier 15 and the base 11, and is conducive to realizing the thinning of the motor 1. In addition, the second guide member 122 can provide multi-point support for the anti-shake carrier 15, which is conducive to dispersing stress and preventing excessive concentration of force in a single direction from causing the ball in the second guide member 122 to deform when it is hit, thereby improving the support of the second guide member 122 on the anti-shake carrier 15 and the lens 2 (see Figure 2 ) and other structural support reliability.

[0177] In other implementations, the anti-shake carrier 15 may also be movably connected to the focus carrier 13 in other ways. This application does not limit this in detail.

[0178] Fig.18 yes Fig.16 The shown diagram is a partial cross-sectional view of an embodiment of the motor 1 at line DD.

[0179] like Fig.17 and Fig.18 As shown, exemplarily, the first anti-shake coil 161 can be located on one side of the first anti-shake magnetic component 163, the first anti-shake coil 161 can be arranged facing the first anti-shake magnetic component 163, and the first anti-shake coil 161 and the first anti-shake magnetic component 163 can be arranged along the first direction Z. The first anti-shake coil 161 and the first anti-shake magnetic component 163 can cooperate to drive the anti-shake carrier 15 to move relative to the focus carrier 13 along the second direction X. Among them, the first anti-shake coil 161 is arranged facing the first anti-shake magnetic component 163, which means that the winding plane of the first anti-shake coil 161 faces the first anti-shake magnetic component 163. For example, the winding plane of the first anti-shake coil 161 can be arranged parallel to the XY plane.

[0180] Fig.19 yes Fig.16 The shown diagram is a partial cross-sectional view of an embodiment of the motor 1 at line EE.

[0181] like Fig.17 and Fig.19 As shown, exemplarily, the second anti-shake coil 162 can be located on one side of the second anti-shake magnetic part 164, the second anti-shake coil 162 can be arranged facing the second anti-shake magnetic part 164, and the second anti-shake coil 162 and the second anti-shake magnetic part 164 can be arranged along the first direction Z. The second anti-shake coil 162 and the second anti-shake magnetic part 164 can cooperate to drive the anti-shake carrier 15 to move along the third direction Y relative to the focus carrier 13. Among them, the second anti-shake coil 162 is arranged facing the second anti-shake magnetic part 164, which means that the winding plane of the second anti-shake coil 162 faces the second anti-shake magnetic part 164. For example, the winding plane of the second anti-shake coil 162 can be arranged parallel to the XY plane.

[0182] It can be understood that, in this 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 on 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 on 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 XY direction.

[0183] In other implementations, the number of the first anti-shake coils 161 may be two, and the first anti-shake coils 161 may be respectively located on both sides of the first anti-shake magnetic component 163. The number of the second anti-shake coils 162 may be two, and the second anti-shake coils 162 may be respectively located on both sides of the second anti-shake magnetic component 164. This application does not limit this in detail.

[0184] See also Fig.18 and Fig.19 , and combined with Figure 2 As shown, exemplarily, the first anti-shake coil 161 and the first anti-shake magnetic component 163 can cooperate, and the second anti-shake coil 162 and the second anti-shake magnetic component 164 can cooperate, and can be used to drive the anti-shake carrier 15 to drive the lens 2 to move in any direction on the XY plane relative to the base 11 and the focus carrier 13, thereby offsetting the shaking stroke of the lens 2 on the XY plane, thereby realizing optical image stabilization of the camera module 100 and improving the imaging quality of the camera module 100.

[0185] It is understandable that in the solution where the focus carrier 13 is located on the inner side of the anti-shake carrier 15, the anti-shake carrier 15 needs to drive the focus carrier 13 and the lens 2 to move relative to the base 11 on the XY plane. At this time, there are many moving structural parts in the optical image stabilization process and the total weight is large. The anti-shake carrier 15 requires a larger driving force, and the motor 1 requires a larger anti-shake driving mechanism 16 to meet the demand for a larger anti-shake driving force. Therefore, the motor 1 can be provided with a first anti-shake coil 161 on both sides of the first anti-shake magnetic part 163, and a second anti-shake coil 162 on both sides of the second anti-shake magnetic part 164. However, the solution in which the two anti-shake coils are respectively located on both sides of the anti-shake magnetic part 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 complicated.

[0186] It can be understood that in the scheme in which the anti-shake carrier 15 of the present embodiment is located inside the focus carrier 13, the anti-shake drive mechanism 16 does not need to drive the focus carrier 13 to move along the first direction Z, and the maximum driving force that the anti-shake drive mechanism 16 needs to provide is relatively small. It is not necessary to respectively set a first anti-shake coil 161 on both sides of the first anti-shake magnetic component 163 and a second anti-shake coil 162 on both sides of the second anti-shake magnetic component 164. The size of the anti-shake drive mechanism 16 is relatively small, the overall product size of the motor 1 is relatively small, and the assembly process of the motor 1 is relatively simple.

[0187] Fig. 20 yes Fig.16 The shown diagram is a partial cross-sectional view of an embodiment of the motor 1 at line FF.

[0188] like Fig.17 and Fig. 20As shown, illustratively, the motor 1 may further include an anti-shake magnetic attraction member 192. The anti-shake magnetic attraction member 192 may be made of a material that can generate magnetic force with a magnet or other magnetic components, such as a ferromagnetic material.

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

[0190] In other implementations, the anti-shake magnetic component 192 may also be arranged in other ways, for example, the number of the anti-shake magnetic component 192 may be one, the anti-shake magnetic component 192 may be located between the bottom plate 131 and the first anti-shake coil 161, or the anti-shake magnetic component 192 may be located between the bottom plate 131 and the second anti-shake coil 162. This application does not limit this in detail.

[0191] Exemplarily, the anti-shake magnetic component 192 may be located on a side of the first anti-shake coil 161 away from the first anti-shake magnetic component 163, and may be arranged facing the first anti-shake magnetic component 163, and there may be magnetic force between the anti-shake magnetic component 192 and the first anti-shake magnetic component 163. The anti-shake magnetic component 192 may be located on a side of the second anti-shake coil 162 away from the second anti-shake magnetic component 164, and may be arranged facing the second anti-shake magnetic component 164, and there may be magnetic force between the anti-shake magnetic component 192 and the second anti-shake magnetic component 164.

[0192] It can be understood that the magnetic force between the first anti-shake magnetic component 163 and the anti-shake magnetic suction component 192, and the magnetic force between the second anti-shake magnetic component 164 and the anti-shake magnetic suction component 192 enable the anti-shake carrier 15 to be subjected to the anti-shake magnetic force, thereby maintaining contact between the anti-shake carrier 15, the second guide component 122 and the focus carrier 13, ensuring the connection stability between the anti-shake carrier 15, the second guide component 122 and the focus carrier 13, and avoiding the anti-shake carrier 15 from escaping from the focus carrier 15, etc.

[0193] Exemplarily, during the movement of the anti-shake carrier 15 relative to the focus carrier 13 on the XY plane, the anti-shake carrier 15 may satisfy: -0.2 mm ≤ dx ≤ 0.2 mm, where dx may represent the displacement of the anti-shake carrier 15 along the X-axis direction, and a negative value of dx means that the anti-shake carrier 15 moves relative to the focus carrier 13 along the negative direction of the X-axis, and a positive value of dx means that the anti-shake carrier 15 moves relative to the focus carrier 13 along the positive direction of the X-axis.

For example, Fy may 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 focus carrier 13 in the XY plane, the anti-shake magnetic force in the Z-axis direction received by the anti-shake carrier 15 may satisfy: 200N≤Fz≤210N, wherein Fz may represent the component force in the Z-axis direction of the anti-shake magnetic force received by the anti-shake carrier 15 when the anti-shake carrier 15 moves relative to the focus carrier 13 in the XY plane, and a negative value of Fz means that when the anti-shake carrier 15 moves relative to the focus carrier 13 in the XY plane, the component force in the Z-axis direction of the anti-shake magnetic force received by the anti-shake carrier 15 is oriented in the negative direction of the Z-axis.

For example, Fz may be equal to 200N, 204N, 207N, 210N or 215N, etc.

[0197] Illustratively, when the anti-shake carrier 15 moves relative to the focus carrier 13 on the XY plane, the anti-shake magnetic force applied to the anti-shake carrier 15 is relatively large, and the anti-shake carrier 15 can be restored to a position where the displacement dx of the anti-shake carrier 15 is 0 due to the magnetic force.

[0198] In other embodiments, Fx, Fy and Fz may satisfy other ranges. Specifically, the present application is not limited thereto.

[0199] Illustratively, when the first anti-shake coil 161 is energized, an anti-shake driving force may be generated between the first anti-shake coil 161 and the first anti-shake magnetic member 163 , thereby driving the anti-shake carrier 15 to move along the second direction X in the XY plane relative to the focusing carrier 13 .

[0200] Exemplarily, during the movement of the anti-shake carrier 15 relative to the focus carrier 13 along the second direction X, the anti-shake driving force received by the anti-shake carrier 15 in the X-axis direction may satisfy: -100N≤Fx≤-70N, wherein Fx may represent the component force in the X-axis direction of the anti-shake driving force received by the anti-shake carrier 15 when the anti-shake carrier 15 moves relative to the focus carrier 13 along the second direction X, and a negative value of Fx means that when the anti-shake carrier 15 moves relative to the focus carrier 13 along the second direction X, the component force in the X-axis direction of the anti-shake driving force received by the anti-shake carrier 15 is oriented in the negative direction of the X-axis.

For example, Fy may be equal to -1N, -0.8N, -0.4N, 0, 0.4N, 0.8N or 1N, etc.

[0210] In other embodiments, Fx, Fy and Fz may satisfy other ranges. Specifically, the present application is not limited thereto.

[0211] The above specifically introduces the relevant structures of the motor 1 in some embodiments in combination with the relevant drawings. The following will introduce the relevant technical problems that can be solved by the motor 1 in some embodiments in combination with the relevant drawings.

[0212] See also Figures 16 to 19 It can be understood that, in this embodiment, the anti-shake carrier 15 is located on the inner side of the focus carrier 13, that is, the motor 1 of this embodiment is a "focus support anti-shake" motor structure, the first anti-shake coil 161 and the first anti-shake magnetic part can cooperate, the second anti-shake coil 162 and the second anti-shake magnetic part 164 can cooperate, and are used to drive the anti-shake carrier 15 to complete optical image stabilization, that is, the load of the anti-shake driving mechanism 16 of this embodiment is small. Then, the anti-shake driving mechanism 16 needs to generate a small driving force, the size of the anti-shake driving mechanism 16 is small, and the size of the motor 1 is small, which is conducive to the miniaturization of the motor 1. In addition, the anti-shake carrier 15 is movably connected to the focus carrier 13 through a ball group, the friction resistance between the anti-shake carrier 15 and the focus carrier 13 is small, the anti-shake driving force required by the anti-shake carrier 15 is small, the size of the anti-shake driving mechanism 16 is small, and the size of the motor 1 is small, which is conducive to the miniaturization of the motor 1.

[0213] See also Fig.18 and Fig.19 It can be understood that, during the focusing process, the focusing coil 142 can move along the first direction Z with the focusing carrier 13. In other words, during the focusing process, the focusing drive mechanism 14 of this embodiment is a moving coil design. In this way, it is possible to prevent the focusing magnetic component 141 from generating magnetic interference with the first anti-shake magnetic component 163, the second anti-shake magnetic component 164 or other magnetic structural components.

[0214] See also Fig.18 and Fig.19 It can be understood that the focus coil 142 is fixedly connected to the focus carrier 13. The first anti-shake coil 161 and the second anti-shake coil 162 are both fixedly connected to the focus carrier 13, and the motor 1 can electrically connect the focus coil 142, the first anti-shake coil 161 and the second anti-shake coil 162 by arranging a structural member on the focus carrier 13. In this way, compared with the solution of arranging the focus coil 142 on the focus carrier 13 and arranging the first anti-shake coil 161 and the second anti-shake coil 162 on the anti-shake carrier 15, the electrical connection method of the solution of this embodiment is simpler.

[0215] See also Fig.16 , Fig.18 as well as Fig.19It can be understood that by arranging the first anti-shake coil 161 and the first anti-shake magnetic component 163 along the first direction Z, and arranging the second anti-shake coil 162 and the second anti-shake magnetic component 164 along the first direction Z, the size of the motor 1 in the XY direction can be reduced.

[0216] See also Fig.16 , Fig.18 as well as Fig.19 It can be understood that the first anti-shake coil 161 is located on one side of the first anti-shake magnetic component 163, and the second anti-shake coil 162 is located on one side of the second anti-shake magnetic component 164. The anti-shake drive mechanism 16 is arranged reasonably, 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-shake coil 161, the second anti-shake coil 162, the first anti-shake magnetic component 163, and the second anti-shake magnetic component 164 and other structural components can be reduced.

[0217] See also Fig.16 It can be understood that the first anti-shake magnetic component 163 and the second anti-shake magnetic component 164 are both Halbach magnet arrays, and the anti-shake driving force roughly along the second direction X generated by the cooperation of the first anti-shake coil 161 and the first anti-shake magnetic component 163 and the anti-shake driving force roughly along the third direction Y generated by the cooperation of the second anti-shake coil 162 and the second anti-shake magnetic component 164 are relatively large, which can drive the anti-shake carrier 15 to complete optical image stabilization.

[0218] See also Fig.11 It can be understood that the magnetic force between the focus magnetic member 191 and the focus magnetic member 141 maintains contact between the base 11, the first guide member 121 and the focus carrier 13. During the focusing process of the motor 1, the focus carrier 13 is not prone to tipping over due to movement. In addition, the focus magnetic member 191 and the focus carrier 13 are an integrally formed structure, so that the assembly tolerance of the focus magnetic member 191 is small, thereby reducing the fluctuation of the magnetic force between the focus magnetic member 191 and the focus magnetic member 141, and improving the movement stability of the motor 1. Compared with the structures of other focus magnetic attraction schemes, the structure of the focus magnetic attraction scheme of this embodiment is simpler.

[0219] See also Fig.17 and Fig. 20 It can be understood that the magnetic force between the anti-shake magnetic member 192 and the first anti-shake magnetic member 163 and the second anti-shake magnetic member 164 keeps the focus carrier 13, the second guide member 122 and the anti-shake carrier 15 in contact. During the anti-shake process of the motor 1, the anti-shake carrier 15 is not prone to tipping over due to movement. In addition, compared with the structures of other anti-shake magnetic solutions, the structure of the anti-shake magnetic solution of this embodiment is simpler.

[0220] The above text specifically introduces the relevant structures of the motor 1 in some embodiments and the technical problems that the motor 1 in some embodiments can solve in combination with the relevant drawings. The following text will introduce the relevant structures of the motor 1 in some embodiments in combination with the relevant drawings. It can be understood that the relevant designs of the motor 1 shown in the above text can also be directly applied to the structural design of the motor 1 shown below without conflict. Among them, most of the technical contents that are the same as those of the motor 1 shown in the above text will not be repeated below.

[0221] First implementation: Please refer to Figure 21 to Figure 23 , Fig.21 yes Figure 4 The electrical connector 17 shown is a schematic structural diagram of an embodiment. Fig. 22 yes Fig.21 The electrical connector 17 is shown as a schematic structural diagram at another angle. Fig.23 yes Fig.21 The electrical connector 17 is shown in a schematic structural diagram at another angle.

[0222] Exemplarily, the electrical connector 17 includes a first fixing portion 171 , a deformable portion 172 and a second fixing portion 173 , and the deformable portion 172 is connected between the first fixing portion 171 and the second fixing portion 173 .

[0223] Exemplarily, the second fixing portion 173 includes a first portion 1731 and a second portion 1732 . The first portion 1731 may be located at one side of the second portion 1732 and fixedly connected to the second portion 1732 .

[0224] Exemplarily, the second portion 1732 of the second fixing portion 173 may be provided with a pin end 17321 , and the pin end 17321 may be used for fixed connection with other structural members.

[0225] Fig.24 yes Figure 3 The motor 1 shown in FIG. 1 is a schematic diagram of a partial structure of an embodiment of the present invention. Figure 7 .

[0226] like Fig.24 As shown, the motor 1 further includes a driving chip 193, and the driving chip 193 can be fixedly connected to the electrical connector 17. Exemplarily, the driving chip 193 can be fixedly connected to the first portion 1731 of the second fixing portion 173, and electrically connected to the first portion 1731.

[0227] Fig.25 yes Figure 3 The motor 1 shown in FIG. 1 is a schematic diagram of a partial structure of an embodiment of the present invention. Figure 8 .

[0228] like Fig.25As shown, the electrical connector 17 may be located on a side of the bottom 111 of the base 11 close to the side 112 and fixedly connected to the base 11. Exemplarily, the first fixing portion 171 of the electrical connector 17 may be fixedly connected to the base 11. The first fixing portion 171 may be fixedly connected to the bottom 111 of the base 11.

[0229] Fig.26 yes Figure 3 The motor 1 shown in FIG. 1 is a schematic diagram of a partial structure of an embodiment of the present invention. Figure 9 . Fig. 27 yes Fig.26 The shown diagram is a partial cross-sectional view of an embodiment of the motor 1 at line GG.

[0230] like Fig.26 and Fig. 27 As shown, the second fixing portion 173 of the electrical connector 17 can be fixedly connected to the focusing carrier 13. Exemplarily, the first portion 1731 of the second fixing portion 173 can be fixedly connected to the second side plate 133 of the focusing carrier 13, the second portion 1732 of the second fixing portion 173 of the electrical connector 17 can be located on a side of the bottom plate 131 of the focusing carrier 13 close to the base 11, and the second portion 1732 can be fixedly connected to the bottom plate 131. The deformation portion 172 of the electrical connector 17 can be located between the focusing carrier 13 and the bottom 111 of the base 11.

[0231] Exemplarily, the driving chip 193 may be located on a side of the first portion 1731 of the second fixing portion 173 close to the focusing carrier 13. It is understandable that, compared with the solution in which the driving chip 193 is located on a side of the electrical connector 17 away from the focusing carrier 13, the first portion 1731 of the second fixing portion 173 of the electrical connector 17 of this embodiment may not need to be bent at a large angle toward the second portion 1732.

[0232] See also Fig.26 and Fig. 27 , and combined with Fig. 22 and Fig.23 As shown, exemplarily, during the movement of the focusing carrier 13 relative to the base 11 along the first direction Z, the position of the first fixing portion 171 of the electrical connector 17 relative to the base 11 may remain unchanged, and the second fixing portion 173 of the electrical connector 17 may deform as the focusing carrier 13 moves relative to the base 11 along the first direction Z, and the deformation portion 172 of the electrical connector 17 may have an elastic force.

[0233] It can be understood that the focus coil 142 can be electrically connected to the base 11 through the second fixing portion 173 of the electrical connector 17, and the first anti-shake coil 161 and the second anti-shake coil 162 can be electrically connected to the base 11 through the second fixing portion 173 of the electrical connector 17. In this way, the structure of the electrical connection between the focus 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 portion 172 is connected between the first fixing portion 171 and the second fixing portion 173. During the process in which the second fixing portion 173 moves along the first direction Z with the focus carrier 13 relative to the base 11, the deformation portion 172 can be deformed, so that the electrical connection between the focus coil 142, the first anti-shake coil 161 and the second anti-shake coil 162 and the base 11 is ensured, while the movement of the focus carrier 13 is not affected.

[0234] like Figure 21 to Figure 23 As shown, exemplarily, the deformation portion 172 may be provided with a through hole 1721. The through hole 1721 may be a bar-shaped hole, and the through hole 1721 may extend along the length extension direction of the deformation portion 172.

[0235] Exemplarily, the deformation part 172 of the electrical connector 17 of some embodiments is not provided with a through hole 1721. It can be understood that, compared with the solution in which the deformation part 172 is not provided with a through hole 1721, the through hole 1721 of the deformation part 172 in this embodiment makes the deformation part 172 bifurcated, the width of the deformation part 172 along the second direction X or the third direction Y is small, the K value of the electrical connector 17 of this 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 may represent the K value of the electrical connector 17 in the Z-axis direction. Kx may represent the K value of the electrical connector 17 in the X-axis direction. Ky may represent the K value of the electrical connector 17 in the Y-axis direction. For example, Kz may be equal to 2, 3.8, or 4, etc. Kx may be equal to 138, 139.6, or 141, etc. Ky may be equal to 278, 280.4, or 283, etc.

[0237] Exemplarily, the electrical connector 17 having the deformation portion 172 of the through hole 1721 satisfies: 1≤Kz≤3, 55≤Kx≤62, 45≤Ky≤53, for example, Kz may be equal to 1, 2 or 3, etc., Kx may be equal to 56, 58 or 60, etc., Ky may be equal to 46, 48 or 51, etc. In other embodiments, Kz, Kx and Ky may all meet other ranges. Specifically, this application is not limited.

[0238] It is understandable that Fig.21 To Attachment Fig.23 Kz, Kx and Ky are schematically shown in FIG. Fig.21 To Attachment Fig.23 The length of the dotted line does not represent the actual size of Kz, Kx and Ky.

[0239] In one embodiment, a comparison of the K value of the electrical connector 17 of the deformation portion 172 without the through hole 1721 and the K value of the electrical connector 17 of the deformation portion 172 with the through hole 1721 is shown in Table 1 below.

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

[0241] KZ Kx Ky The electrical connector 172 of the deformation portion 172 without the through hole 1721 3.8 139.6 280.4 The electrical connector 17 has a deformable portion 172 with a through hole 1721 2 58 48

[0242] It can be understood that, compared with the electrical connector 17 with the deformation portion 172 without the through hole 1721, the K value of the electrical connector 17 with 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, when the deformation portion 172 produces the same deformation amount, the elastic force of the electrical connector 17 of this embodiment is smaller. In this way, in the process that the second fixing portion 173 of the electrical connector 17 moves along the first direction Z with the focus carrier 13 and the anti-shake carrier 15, the elastic force of the electrical connector 17 is smaller, and the elastic force of the electrical connector 17 has less influence on the focusing process, which is 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 focus 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 also smaller, and the driving force required to be provided by the focus drive mechanism 14 is also smaller, which is beneficial to reduce the volume of the focus drive mechanism 14.

[0243] like Fig.26 and Fig. 27 As shown, exemplarily, the focusing carrier 13 further includes a first convex column 136. In one embodiment, the number of the first convex columns 136 can be multiple, and the multiple first convex columns 136 can be respectively convexly disposed on the first side plate 132, the second side plate 133, the first convex block 134 and the second convex block 135 of the focusing carrier 13.

[0244] Exemplarily, the anti-shake carrier 15 further includes a second convex column 153, and the second convex column 153 may be convexly disposed on one side of the anti-shake carrier 15. In one implementation, the number of the second convex column 153 may be plural.

[0245] Exemplarily, the motor 1 further includes a reed 194. In one embodiment, the number of the reeds 194 may be multiple, for example, the number of the reeds 194 may be four.

[0246] Exemplarily, the reed 194 may be a metal spring structure. The reed 194 may be deformed under external force, in other words, the reed 194 may be stretched or compressed under the action of external force. When the anti-shake carrier 15 does not displace relative to the focus carrier 13, the reed 194 may be in a non-deformed state. In other embodiments, when the anti-shake carrier 15 does not displace relative to the focus carrier 13, the reed 194 may also be in a stretched state or a compressed state.

[0247] Exemplarily, one end of the reed 194 can be sleeved on the first protrusion 136 of the focusing carrier 13 and fixedly connected to the focusing carrier 13, and the other end can be sleeved on the second protrusion 153 of the anti-shake carrier 15 and fixedly connected to the anti-shake carrier 15. The reed 194 can be connected between the focusing carrier 13 and the anti-shake carrier 15.

[0248] It is understandable that, since the reed 194 is connected between the anti-shake carrier 15 and the focus carrier 13, the movement of the anti-shake carrier 15 causes the reed 194 to undergo elastic deformation and have an elastic force, so that the anti-shake carrier 15 is reset, and the anti-shake carrier 15 can return to a position where the displacement dx is 0. The reed 194 can also provide an anti-torsion force to the anti-shake carrier 15, hindering the rotation of the anti-shake carrier 15. In addition, in this embodiment, the first anti-shake coil 161 is located on one side of the first anti-shake magnetic component 163, and the second anti-shake coil 162 is located on one side of the second anti-shake magnetic component 164, which can reduce the risk of short circuits between the first anti-shake coil 161, the second anti-shake coil 162 and the reed 194 and other structural components, thereby improving the reliability of the motor 1.

[0249] Fig.28 yes Figure 3 The motor 1 shown in FIG. 1 is a schematic diagram of a partial structure of an embodiment of the present invention. Figure 10 . Fig.29 yes Figure 3 The motor 1 shown in FIG. 1 is a schematic diagram of a partial structure of an embodiment of the present invention. Figure 10 one.

[0250] See also Fig.28 and Fig.29 , and combined with Fig.26As shown, the motor 1 also includes a wiring 195. The wiring 195 can be embedded in the focus carrier 13. Exemplarily, a portion of the wiring 195 can be embedded in the bottom plate 131 of the focus carrier 13 and exposed relative to the bottom plate 131. A portion of the wiring 195 can be embedded in the first side plate 132 of the focus carrier 13 and exposed relative to the first side plate 132. A portion of the wiring 195 can be embedded in the second side plate 133 of the focus carrier 13 and exposed relative to the second side plate 133. A portion of the wiring 195 can be embedded in the first bump 134 of the focus carrier 13 and exposed relative to the first bump 134. A portion of the wiring 195 can be embedded in the second bump 135 of the focus carrier 13 and exposed relative to the second bump 135.

[0251] For example, the number of the wiring 195 may be multiple. A portion of the wiring 195 may be connected to the focus coil 142 (see Fig.18 ) is electrically connected. A portion of the wiring 195 can be electrically connected to a focus sensor (not shown in the drawings), wherein the focus sensor can detect the position change of the focus carrier 13 and the anti-shake carrier 15 when they move along the first direction Z. A portion of the wiring 195 can be electrically connected to the first anti-shake coil 161 (see Fig.26 ) is electrically connected. A portion of the wiring 195 can be connected to the second anti-shake coil 162 (see Fig.26 ) is electrically connected, and a portion of the wiring 195 can be electrically connected to an anti-shake sensor (not shown in the drawings), and the anti-shake sensor can detect the position change of the anti-shake carrier 15 when it moves on the XY plane.

[0252] Exemplarily, the wiring 195 includes a bent portion 1951, and the bent portion 1951 may be located at one end of the wiring 195. It can be understood that the wiring 195 is embedded in the focus carrier 13, and the structure of the motor 1 is simpler.

[0253] In other embodiments, the wiring 195 may also be fixedly connected to the focus carrier 13 by welding, gluing, etc. The structure and quantity of the wiring 195 may also be different from the attached Fig.28 Different from the illustration, the routing 195 can be flexibly arranged according to actual needs.

[0254] like Fig.29 As shown, the trace 195 can be fixedly connected and electrically connected to the electrical connector 17. Exemplarily, the bent portion 1951 of the trace 195 can be arranged along the first direction Z with the pin end 17321 of the second portion 1732 of the second fixing portion 173, and fixedly connected to the pin end 17321. It can be understood that the bent portion 1951 of the trace 195 makes the connection process between the trace 195 and the electrical connector 17 simpler.

[0255] Exemplarily, the bent portion 1951 may be electrically connected to the pin end 17321 by welding or the like. In other embodiments, the bent portion 1951 may be electrically connected to the pin end 17321 by other means.

[0256] See also Figure 27 to Figure 29 , and combined with Fig.18 As shown, the focus coil 142 can be electrically connected to the driving chip 193 through the first part 1731 of the second fixing part 173 of the electrical connector 17, and the wiring 195 can form a current loop with the first part 1731 of the second fixing part 173 of the electrical connector 17, the focus coil 142, and the driving chip 193. It can be understood that the driving chip 193 can control the current condition of the focus coil 142 (for example, whether the current is passed or the magnitude of the current when the current is passed) through the wiring 195 and the first part 1731 of the second fixing part 173 of the electrical connector 17 to control the focusing process of the motor 1.

[0257] like Figure 26 to Figure 29 As shown, the first anti-shake coil 161 can be electrically connected to the driving chip 193 through the second part 1732 of the second fixed part 173 of the electrical connector 17, and the wiring 195 can form a current loop with the second part 1732 of the second fixed part 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 part 1732 of the second fixed part 173 of the electrical connector 17, and the wiring 195 can form a current loop with the second part 1732 of the second fixed part 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 conditions of the first anti-shake coil 161 and the second anti-shake coil 162 (for example, whether current is passed or the magnitude of the current when it is passed, etc.) through the wiring 195 and the second part 1732 of the second fixed part 173 of the electrical connector 17 to control the optical anti-shake process of the motor 1.

[0258] Second implementation: Please refer to Fig.30 , Fig.30 yes Fig.21 The schematic diagram of the structure of the electrical connector 17 in another embodiment is shown. 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 this embodiment without conflict. Among them, most of the technical contents that are the same as those of the motor 1 shown in the first embodiment will not be repeated in this embodiment.

[0259] Exemplarily, the electrical connector 17 includes a first fixing portion 171 , a deformable portion 172 and a second fixing portion 173 , and the deformable portion 172 is connected between the first fixing portion 171 and the second fixing portion 173 .

[0260] Exemplarily, in the thickness direction of the deformation portion 172 , the deformation portion 172 includes a plurality of deformation sub-portions 1722 .

[0261] Exemplarily, each layer of the deformable sub-portion 1722 includes a first end 17221 and a second end 17222. The first end 17221 of each layer of the deformable sub-portion 1722 can be fixedly connected to the first fixed portion 171, and the second end 17222 of each layer of the deformable sub-portion can be fixedly connected to the second fixed portion 173. The deformable sub-portions 1722 of two adjacent layers can be arranged at intervals to form a hollow area 17223. In other words, the deformable portions 172 of the electrical connector 17 of this embodiment are arranged in layers. In other embodiments, the first end 17221 of each layer of the deformable sub-portion 1722 can be fixedly connected to each other and to the first fixed portion 171. The second end 17222 of each layer of the deformable sub-portion 1722 can be fixedly connected to each other and to the second fixed portion 173.

[0262] For example, compared with a solution in which the deformation portion 172 is not arranged in layers, the deformation portion 172 arranged in layers in this embodiment makes the thickness of the deformation portion 172 along the first direction Z smaller, and the K value of the electrical connector 17 of this embodiment can be reduced.

[0263] It can be understood that, compared with the electrical connector 17 without the layered deformation part 172, the K value of the electrical connector 17 with the layered deformation part 172 of this embodiment is reduced. Fig. 27 ) and anti-shake carrier 15 (see Fig. 27 ) During the movement along the first direction Z, the elastic force of the electrical connector 17 is relatively small, and the elastic force of the electrical connector 17 has relatively small influence on the focusing process, which is beneficial to improving the movement stability 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 relatively small, and the driving force required for the deformation is also relatively small. The driving force required to be provided by the focus driving mechanism 14 is also relatively small, which is beneficial to reducing the volume of the focus driving mechanism 14.

[0264] For example, each layer of the deformable sub-portion 1722 may also be provided with a through hole 17224, and the through hole 17224 of the deformable sub-portion 1722 may be strip-shaped and extend along the length extension direction of the deformable sub-portion 1722. In other embodiments, each layer of the deformable sub-portion 1722 may not be provided with a through hole 17224.

[0265] The third implementation method: Please refer to Fig.31 , Fig.31 yes Fig.21 The schematic diagram of the structure of the electrical connector 17 in another embodiment is shown. It can be understood that the relevant 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 this embodiment without conflict. Among them, most of the technical contents that are the same as those of the motor 1 shown in the first embodiment and / or the second embodiment will not be repeated in this embodiment.

[0266] Exemplarily, the electrical connector 17 includes a first fixing portion 171 , a deformable portion 172 and a second fixing portion 173 , and the deformable portion 172 is connected between the first fixing portion 171 and the second fixing portion 173 .

[0267] For example, at least a portion of the deformable portion 172 may be curved. In other words, the deformable portion 172 of this embodiment may be extended. Compared with a solution in which the deformable portion 172 is not extended, the K value of the electrical connector 17 of this embodiment can be reduced. In this way, when the second fixing portion 173 of the electrical connector 17 moves with the focus carrier 13 (see Fig. 27 ) and anti-shake carrier 15 (see Fig. 27 ) During the movement along the first direction Z, the elastic force of the electrical connector 17 is relatively small, and the elastic force of the electrical connector 17 has relatively small influence on the focusing process, which is beneficial to improving the movement stability 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 relatively small, and the driving force required for the deformation is also relatively small. The driving force required to be provided by the focus driving mechanism 14 is also relatively small, which is beneficial to reducing the volume of the focus driving mechanism 14.

[0268] In other embodiments, at least a portion of the deformation portion 172 may also be in a spiral shape, a zigzag shape, or the like.

[0269] The above text introduces the relevant structures of some embodiments of the motor 1 in combination with the relevant drawings, and the following text introduces the relevant structures of the motor 1 in some embodiments in combination with the relevant drawings. It can be understood that the relevant designs of the motor 1 shown in the above text can also be directly applied to the structural design of the motor 1 shown below without conflict. Among them, most of the technical contents that are the same as those of the motor 1 shown in the above text will not be repeated below.

[0270] Fig.32 yes Figure 3 The structure of the motor 1 shown in one embodiment is schematically shown in FIG. Figure 10 two.

[0271] like Fig.32As shown, illustratively, the pressing piece 181 may be roughly annular. The pressing piece 181 may be fixed to the side of the anti-shake carrier 15 that faces away from the base 11, and the pressing piece 181 may also be fixedly connected to the second side plate 133 of the focus carrier 13. It is understandable that the pressing piece 181 may cooperate with the focus carrier 13 to limit the movement stroke of the anti-shake carrier 15 in the first direction Z to prevent the anti-shake carrier 15 from being separated from the focus carrier 13 during the optical image stabilization process.

[0272] Fig.33 yes Figure 4 The structure of the housing 182 shown is schematically shown at another angle.

[0273] like Fig.33 As shown, illustratively, the housing 182 may include a top 1821, a first side 1822, a second side 1823, a third side 1824, and a fourth side 1825. It is understood that although the housing 182 is divided into five parts for introduction, it does not affect that the housing 182 may be an integrally formed structure. In addition, in other embodiments, the housing 182 may also be formed by different independent structural parts through an assembly process. For example, the first side 1822 and the second side 1823 of the housing 182 may be two independent structural parts fixed to the top 1821 of the housing 182 by welding, bonding, etc.

[0274] Exemplarily, the first side portion 1822 , the second side portion 1823 , the third side portion 1824 , and the fourth side portion 1825 may be located on one side of the top portion 1821 and fixedly connected to the top portion 1821 .

[0275] Fig.34 yes Figure 3 The shown diagram is a partial cross-sectional view of an embodiment of the motor 1 at line HH.

[0276] like Fig.33 and Fig.34 As shown, exemplarily, the shell 182 can be adapted to the shape of the base 11, the shell 182 can be covered on the base 11, and the first side 1822, the second side 1823, the third side 1824 and the fourth side 1825 of the shell 182 can be fixedly connected to the base 11.
