Description

TECHNICAL FIELD

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

[0002] With the rapid development of electronic technology, users have higher and higher requirements for electronic devices with photographing and filming functions. The electronic device includes a camera module, and a motor in the camera module can realize an optical image stabilization (OIS) function. The optical image stabilization refers to reducing the phenomenon of instrument jitter in the process of capturing optical signals through optical components, such as lens settings, in a camera or other similar imaging instruments, thereby improving the imaging quality.

[0003] The motor in the camera module in the related art is prone to rotation and crosstalk problems when performing anti-shake in different directions, thereby affecting the anti-shake effect and resulting in low imaging quality. SUMMARY

[0004] Embodiments of the present application aim to provide a motor, a camera module and an electronic device to avoid the problems of rotation and crosstalk of the motor when performing anti-shake in different directions, thereby improving the imaging quality. The specific technical solutions are as follows:

[0005] Embodiments of the first aspect of the present application provide a motor, which includes a fixed assembly, a movable assembly, a guide and a driving assembly. The movable assembly is arranged opposite to the fixed assembly. The guide is arranged between the fixed assembly and the movable assembly and is respectively connected with the two assemblies in sliding mode, so that the movable assembly can move relative to the fixed assembly along a first direction or a second direction. The driving assembly is arranged between the fixed assembly and the movable assembly and is respectively connected with the two assemblies, and is used for driving the movable assembly to move along the first direction or the second direction. The first direction, the second direction and the optical axis direction are perpendicular to each other.

[0006] It can be seen from the above that the motor of the embodiment of the application comprises a fixed assembly, a movable assembly, a guide and a driving assembly; the movable assembly is arranged opposite to the fixed assembly, the guide is arranged between the two and is in sliding connection with the two respectively, the guide has a guiding effect, so that the movable assembly can move relative to the fixed assembly in a first direction or a second direction; the driving assembly is arranged between the fixed assembly and the movable assembly and is connected with the two respectively, and is used for driving the movable assembly to move in the first direction or the second direction; the driving assembly cooperates with the guide, so that the movable assembly moves relative to the fixed assembly in the first direction or the second direction under the driving of the driving assembly and the guiding effect of the guide; that is, when the movable assembly moves in the first direction, it does not move in the second direction, and when it moves in the second direction, it does not move in the first direction, thereby realizing decoupling of the movement of the movable assembly, so that the movements of the movable assembly in the first direction and the second direction do not affect each other, the problem of rotation and cross talk of the motor in the related art when performing anti-shake in different directions is avoided, and the imaging quality is improved, thereby achieving the optical anti-shake effect of decoupling.

[0007] In some embodiments of the application, the guide comprises a first part and a second part arranged in connection;

[0008] The first part extends in the first direction and is in sliding connection with the movable assembly;

[0009] The second part extends in the second direction and is in sliding connection with the fixed assembly.

[0010] As can be seen from the above, the first part extends in the first direction to realize the movement of the movable assembly relative to the fixed assembly in the first direction, and the second part extends in the second direction to realize the movement of the movable assembly relative to the fixed assembly in the second direction, thereby realizing decoupling of the movement of the movable assembly; the first part is in sliding connection with the movable assembly, and the second part is in sliding connection with the fixed assembly, so that the movement process is smooth in the sliding connection mode, which is beneficial to improving the anti-shake effect and thereby further improving the imaging quality.

[0011] In some embodiments of the application, the movable assembly comprises:

[0012] a base arranged opposite to the fixed assembly and connected with the driving assembly;

[0013] a first connecting piece fixedly connected with the base and in sliding connection with the first part of the guide, so that the base moves in the first direction under the action of the driving assembly.

[0014] As can be seen from the above, compared with the direct connection of the guide and the base, the first connecting piece is separately arranged, the connection between the base and the guide is realized through the first connecting piece, the arrangement mode is more flexible, and maintenance is facilitated.

[0015] In some embodiments of the present application, the fixing assembly comprises:

[0016] The housing is arranged opposite to the base and connected with the driving assembly;

[0017] The second connecting piece is fixedly connected with the housing and slidingly connected with the second part of the guide piece, so that the base and the guide piece move along the second direction under the action of the driving assembly.

[0018] As can be seen from the above, compared with the direct connection of the guide piece and the housing, the second connecting piece is separately arranged, and the connection between the housing and the guide piece is realized through the second connecting piece, so that the arrangement is more flexible and convenient for maintenance.

[0019] In some embodiments of the present application, the number of the first connecting piece and the second connecting piece is at least two;

[0020] The at least two first connecting pieces are arranged at intervals along the first direction;

[0021] The at least two second connecting pieces are arranged at intervals along the second direction.

[0022] As can be seen from the above, by arranging at least two connecting points in the first direction and the second direction, the shaking between the guide piece and the base or the housing can be prevented, and the guiding effect of the guide piece can be more accurate.

[0023] In some embodiments of the present application, the motor further comprises a support piece;

[0024] The support piece is arranged between the fixing assembly and the movable assembly and is arranged at intervals with the guide piece, and is used for supporting the fixing assembly and the movable assembly together with the guide piece.

[0025] As can be seen from the above, the support piece is arranged between the fixing assembly and the movable assembly and is arranged at intervals with the guide piece, and the support piece and the guide piece provide dispersed support points, provide support force in the moving process, and can prevent the overturning caused by the too concentrated or uneven support points between the fixing assembly and the movable assembly. The support piece has the effect of preventing overturning and can improve the stability of the anti-shake feature. At the same time, the support piece and the guide piece are arranged in the same layer, which is a single-layer design, and is beneficial to reduce the size of the motor in the optical axis direction.

[0026] In some embodiments of the present application, the movable assembly is provided with a first accommodating groove;

[0027] The fixing assembly is provided with a second accommodating groove, and the second accommodating groove and the first accommodating groove are arranged opposite to each other;

[0028] The support member is disposed in the first receiving groove and the second receiving groove.

[0029] As can be seen from the above, the first and second receiving grooves have a limiting function for the support member, preventing it from detaching from the fixed and movable components during the movement of the movable component. Simultaneously, the support member being positioned within the first and second receiving grooves helps save space in the motor's optical axis direction, facilitating the miniaturization of the motor design.

[0030] In some embodiments of this application, a first metal sheet is provided in the first receiving groove;

[0031] The second receiving groove is provided with a second metal sheet;

[0032] The support component is a ball bearing, which is in rolling connection with the first metal sheet and the second metal sheet.

[0033] As can be seen from the above, the ball bearings are spherical, which provides strong pressure resistance. The placement of the first and second metal plates ensures that the surfaces of both the movable and fixed components that contact the ball bearings are flat metal planes. These flat metal planes have high rigidity, reducing the risk of dents. Simultaneously, the flat ball bearings also reduce frictional resistance, making the movement of the movable components smoother and improving the stability of the anti-shake characteristics.

[0034] In some embodiments of this application, the driving component includes:

[0035] At least two magnets are fixedly connected to the movable component;

[0036] At least two coils are fixedly connected to the fixing assembly and are arranged opposite to the at least two magnets in the optical axis direction; the coils are configured to generate an interaction force with the magnets arranged opposite to them in the first direction or the second direction when they are energized.

[0037] As can be seen from the above, since the coil and the fixed component are fixedly connected, and the magnet and the movable component are fixedly connected, the direction of the interaction force generated between the magnet and the coil can be controlled by controlling the on and off state of the coil, so that the magnet drives the movable component to move along the first direction or the second direction under the action of the coil.

[0038] In some embodiments of this application, the at least two magnets include:

[0039] The first magnet has its N pole and S pole distributed along the first direction;

[0040] The second magnet has its N pole and S pole distributed along the second direction.

[0041] As can be seen from the above, the N pole and S pole of the first magnet are distributed along the first direction, which is used to generate an interaction force with the coil in the first direction, so that the movable component moves together with the first magnet in the first direction; the N pole and S pole of the second magnet are distributed along the second direction, which is used to generate an interaction force with the coil in the second direction, so that the movable component moves together with the magnet in the second direction.

[0042] In some embodiments of this application, the motor further includes: a sensor;

[0043] The sensors are configured in a one-to-one correspondence with the coils;

[0044] The sensor is located between the fixed component and the magnet, and is surrounded by the coil.

[0045] As can be seen from the above, placing the sensor at the center of the coil and using the sensor to sense changes in magnetic flux to adjust and correct the lens position results in better image stabilization.

[0046] In some embodiments of this application, the driving component further includes: a magnetic conductive sheet;

[0047] The magnetic conductive sheet is disposed opposite to the magnet, located between the fixing component and the coil, and is fixedly connected to the fixing component.

[0048] As can be seen from the above, the magnetic guide plate can concentrate and confine the magnetic field of the magnet, thereby improving the efficiency of the motor. At the same time, the magnet has a magnetic attraction to the magnetic guide plate. The two are arranged opposite each other, and the magnetic attraction causes the movable component to press against the guide (L-shaped sliding shaft) and the support (ball bearings), providing the guiding function and the reaction force required for movement.

[0049] In some embodiments of this application, a first through hole is provided at the center of the movable component;

[0050] The fixing component has a second through hole at its center; the second through hole corresponds to the position of the first through hole.

[0051] The guide is positioned at the edge of the movable component and the fixed component;

[0052] The guide and the drive assembly are spaced apart from the first through hole and the second through hole;

[0053] The at least two magnets and the at least two coils are disposed on both sides of the first through hole and the second through hole.

[0054] As can be seen from the above, with this configuration, the lens can be placed within the first and second through holes and connected to the base. The base then moves the lens to achieve optical image stabilization. The guide component is located at the edge and does not occupy the lens's space. Furthermore, this configuration saves more space and allows for more even force distribution on the movable components.

[0055] An embodiment of the second aspect of this application provides a camera module, including a lens and a motor according to any embodiment of the first aspect; the lens is fixedly connected to a movable component of the motor.

[0056] As can be seen from the above, the camera module of this application embodiment includes a lens and a motor of any of the above embodiments. The driving component of the motor cooperates with the guide component, so that the movable component moves relative to the fixed component in the first direction or the second direction under the drive of the driving component and the guidance of the guide component. That is, when the movable component moves in the first direction, it does not move in the second direction, and when it moves in the second direction, it does not move in the first direction. This achieves decoupling of the movement of the movable component, so that the movement of the movable component in the first direction and the second direction does not affect each other. This avoids the problem of rotation and crosstalk that easily occurs when the motor performs image stabilization in different directions in the related technology, thereby improving the image quality and achieving the decoupled optical image stabilization effect.

[0057] An embodiment of the third aspect of this application provides an electronic device including a camera module according to any embodiment of the second aspect.

[0058] As can be seen from the above, the electronic device of this application embodiment includes the camera module of any of the above embodiments. The motor in the camera module achieves decoupling of the movement of the movable component, so that the movement of the movable component in the first direction and the second direction does not affect each other. This avoids the problem of rotation and crosstalk that the motor is prone to when performing image stabilization in different directions in the related technology, thereby improving the image quality and achieving the decoupled optical image stabilization effect, thereby improving the image quality of the electronic device.

Detailed Implementation

[0077] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0078] To facilitate a clear description of the technical solutions in the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with essentially the same function and effect. For example, "first swing arm" and "second swing arm" are used to distinguish different swing arms, but do not limit their order. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or position, and that "first" and "second" do not necessarily imply that they are different.

[0079] It should be noted that, in this application, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplarily" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0080] With the rapid development of electronic technology, users have increasingly higher requirements for electronic devices with photo and video recording functions, demanding higher resolution in both photography and video recording. Electronic devices include camera modules, and the motors within these modules can implement optical image stabilization (OIS). OIS refers to the use of optical components, such as lenses, in cameras or other similar imaging instruments to reduce instrument shake during the capture of optical signals, thereby improving image quality. However, in related technologies, the motors in camera modules are prone to rotation and crosstalk problems when performing stabilization in different directions, affecting the stabilization effect and resulting in low image quality. To address these technical problems, this application provides a motor, a camera module, and an electronic device.

[0081] For ease of explanation, the following embodiments use a mobile phone as an example to illustrate the structure of the electronic device.

[0082] This application provides an electronic device with a shooting function. Specifically, the electronic device can be a portable electronic device or other suitable electronic device. For example, the electronic device can be a mobile phone, tablet personal computer, laptop computer, personal digital assistant (PDA), camera, personal computer, laptop computer, in-vehicle equipment, intelligent robot, automotive electronics, wearable device, augmented reality (AR) glasses, AR helmet, virtual reality (VR) glasses, or VR helmet, etc. This application does not limit the specific type of electronic device.

[0083] like Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of an electronic device according to an embodiment of this application. Figure 2 for Figure 1 The exploded structural diagram shows that the electronic device includes a screen 10, a back cover 20, a camera module 30, a motherboard 40, and a camera decorative cover 50. It is understandable that... Figure 1 and Figure 2 This illustration schematically shows some components of an electronic device, the actual shape, size, location, and construction of which are not subject to change. Figure 1 and Figure 2 The limitations. In some other examples, the electronic device may also not include the screen 10 and the camera cover 50.

[0084] Screen 10 is used to display images, videos, etc. Screen 10 includes a light-transmitting cover 11 and a display screen 12. The light-transmitting cover 11 and the display screen 12 are stacked together. The light-transmitting cover 11 is mainly used to protect the display screen 12 and prevent dust. The material of the light-transmitting cover 11 includes, but is not limited to, glass. The display screen 12 can be a flexible display screen or a rigid display screen. For example, the display screen 12 can be an Organic Light-Emitting Diode (OLED) display screen, an Active-Matrix Organic Light-Emitting Diode (AMOLED) display screen, a mini-organic light-emitting diode (MLED) display screen, a microorganic light-emitting diode (LED) display screen, a quantum dot light-emitting diode (QLED) display screen, or a liquid crystal display (LCD).

[0085] The back cover 20 is used to protect the internal electronic components of the electronic device. The back cover 20 includes a back cover 21 and a frame 22. The back cover 21 is located on the side of the display screen 12 away from the light-transmitting cover plate 11 and is stacked on top of the light-transmitting cover plate 11 and the display screen 12. The frame 22 is located between the back cover 21 and the light-transmitting cover plate 11 and is fixed to the back cover 21. For example, the frame 22 can be fixed to the back cover 21 by adhesive. Alternatively, the frame 22 can be integrally formed with the back cover 21, i.e., the frame 22 and the back cover 21 are a single integral structure. The light-transmitting cover plate 11 is fixed to the frame 22 by adhesive. The light-transmitting cover plate 11, the back cover 21, and the frame 22 form an internal housing space for the electronic device. This internal housing space houses the display screen 12.

[0086] The camera module 30 is used to capture photos / videos. The camera module 30 integrates a motor. The motor is used to achieve functions such as automatic focusing (AF), optical image stabilization (OIS), and wide-angle tracking. The camera module 30 is fixed within the internal housing of the electronic device.

[0087] The electronic device also includes a middle plate 23. The middle plate 23 is fixed around the inner surface of the frame 22. For example, the middle plate 23 can be fixed to the frame 22 by welding. The middle plate 23 can also be integrally formed with the frame 22. The middle plate 23 serves as the structural "skeleton" of the electronic device, and the camera module 30 can be fixed and supported on the middle plate 23 by means of threaded connection, snap-fit, welding, etc.

[0088] In some embodiments of this application, such as Figure 2 As shown, the camera module 30 is fixed to the surface of the middle plate 23 near the back cover 21. The light-incident surface of the camera module 30 faces the back cover 21. The back cover 21 has a mounting opening 60. A camera decorative cover 50 covers and is fixed to the mounting opening 60. The camera decorative cover 50 is used to protect the camera module 30. In some embodiments, the camera decorative cover 50 protrudes to the side of the back cover 21 away from the light-transmitting cover plate 11. This configuration increases the mounting space of the camera module 30 within the electronic device along the thickness direction of the electronic device. In other embodiments, the camera decorative cover 50 may also be flush with the back cover 21 or recessed into the internal receiving space of the electronic device. The camera decorative cover 50 has a light-transmitting window 51. The light-transmitting window 51 allows light from the scene to pass through and enter the light-incident surface of the camera module 30. The camera module 30 can be used as a rear camera module or as a front camera module; Figure 2 In the illustrated embodiment, the camera module 30 is used as a rear camera module for an electronic device.

[0089] In some other embodiments of this application, the camera module 30 is fixed to the surface of the middle plate 23 near the light-transmitting cover plate 11. The light-incident surface of the camera module 30 faces the light-transmitting cover plate 11. The display screen 12 is provided with a light path avoidance hole (not shown in the figure). This light path avoidance hole allows light from the scene to pass through the light-transmitting cover plate 11 and then enter the light-incident surface of the camera module 30. In this way, the camera module 30 is used as a front-facing camera module for an electronic device.

[0090] The motherboard 40 is fixed within the internal cavity of the electronic device. For example, the motherboard 40 can be fixed to the middle plate 23 by means of threaded connection, snap-fit, or other methods. When the electronic device does not include the middle plate 23, the motherboard 40 can also be fixed to the surface of the display screen 12 near the back cover 21 by means of threaded connection, snap-fit, or other methods.

[0091] like Figure 3 As shown, Figure 3This is an internal circuit diagram of an electronic device according to an embodiment of this application. The electronic device also includes a computing control unit 41, which can be disposed on the motherboard 40 or on other circuit boards within the electronic device, such as the circuit board where the Universal Serial Bus (USB) device is located. The computing control unit 41 can be an application processor (AP). The computing control unit 41 is electrically connected to the camera module 30. The computing control unit 41 is used to receive and process electrical signals containing image information from the camera module 30. The computing control unit 41 is also used to control the movement of the drive motor of the camera module 30 to achieve AF (Automatic Focusing) movement and / or OIS (Optical Image Stabilization) movement.

[0092] The camera module 30 can be a periscope camera module or a vertical camera module. For example... Figure 4 and Figure 5 As shown, Figure 4 This is a schematic diagram of the structure of the camera module 30 according to an embodiment of this application. Figure 5 This is a schematic diagram of the motor from a first perspective according to an embodiment of this application. For ease of description below, the first direction, the second direction, and the optical axis direction are defined to be perpendicular to each other. The camera module 30 includes a lens 31 and a motor; the motor includes a fixed component 100 and a movable component 200. The lens 31 is fixedly connected to the movable component 200 of the motor and is disposed in the first through hole 212 and the second through hole 112. During optical image stabilization, the fixed component 100 is fixedly connected to the circuit board (not shown in the figure) and remains fixed. The movable component 200 drives the lens 31 to move relative to the fixed component 100 to achieve optical image stabilization. Specifically, the lens 31 can be fixedly connected to the base 210 of the movable component 200.

[0093] The structure of the motor in the embodiments of this application will be described in detail below.

[0094] like Figures 5 to 7 As shown, Figure 6 for Figure 4 A schematic diagram of the exploded structure from a second-person perspective. Figure 7 for Figure 5This application discloses an exploded structural diagram from a first-person perspective, illustrating a motor comprising a fixed component 100 (stator), a movable component 200 (mover), a guide member 300, and a drive component 400. Specifically, the movable component 200 is disposed opposite to the fixed component 100; the guide member 300 is disposed between the fixed component 100 and the movable component 200 and slidably connected to both, enabling the movable component 200 to move relative to the fixed component 100 along a first direction or a second direction; the drive component 400 is disposed between the fixed component 100 and the movable component 200 and connected to both, for driving the movable component 200 to move along the first direction or the second direction.

[0095] The motor in this embodiment includes a fixed component 100, a movable component 200, a guide member 300, and a drive component 400. The movable component 200 is disposed opposite to the fixed component 100, and the guide member 300 is disposed between the two and slidably connected to both. The guide member 300 has a guiding function, enabling the movable component 200 to move relative to the fixed component 100 along a first direction or a second direction. The drive component 400 is disposed between the fixed component 100 and the movable component 200 and connected to both, for driving the movable component 200 to move along the first direction or the second direction. The drive component 400 cooperates with the guide member 300. This allows the movable component 200 to move relative to the fixed component 100 along a first or second direction under the drive of the drive component 400 and the guidance of the guide component 300. That is, when the movable component 200 moves along the first direction, it does not move in the second direction, and when it moves along the second direction, it does not move in the first direction. This achieves decoupling of the movement of the movable component 200, so that the movement of the movable component 200 in the first and second directions does not affect each other. This avoids the problem of rotation and crosstalk that easily occurs when the motor performs image stabilization in different directions in related technologies, thereby improving the imaging quality and achieving a decoupled optical image stabilization effect.

[0096] In some embodiments of this application, such as Figures 5 to 7As shown, the guide member 300 includes a first part 310 and a second part 320 connected together. The first part 310 extends along a first direction and is slidably connected to the movable component 200. The second part 320 extends along a second direction and is slidably connected to the fixed component 100. The first part 310 extends along the first direction to realize the movement of the movable component 200 relative to the fixed component 100 in the first direction, and the second part 320 extends along the second direction to realize the movement of the movable component 200 relative to the fixed component 100 in the second direction, thereby decoupling the movement of the movable component 200. The slidable connection between the first part 310 and the movable component 200, and the slidable connection between the second part 320 and the fixed component 100, ensures smooth movement and improves image stabilization, thereby further improving image quality.

[0097] Optionally, such as Figure 7 As shown, the guide 300 can be an L-shaped shaft, which is an integral structure that is easy to process and install; the first part 310 and the second part 320 can be cylindrical, which is conducive to sliding.

[0098] In some embodiments of this application, such as Figure 6 and Figure 7 As shown, the movable component 200 includes a base 210 (Carrier) and a first connector 220 (Shaft Holer). The base 210 is disposed opposite to the fixed component 100 and connected to the drive component 400. The first connector 220 is fixedly connected to the base 210 and slidably connected to the first part 310 of the guide component 300, so that the base 210 moves in a first direction under the action of the drive component 400. Compared with the guide component 300 and the base 210 being directly connected, the first connector 220 is set separately, and the connection between the base 210 and the guide component 300 is realized through the first connector 220. The setting method is more flexible and easier to maintain.

[0099] In some embodiments of this application, such as Figure 6 and Figure 7 As shown, the fixing component 100 includes a housing 110 and a second connecting member 120 (shaft hub 2). The housing 110 is disposed opposite to the base 210 and connected to the drive component 400. The second connecting member 120 is fixedly connected to the housing 110 and slidably connected to the second part 320 of the guide member 300, so that the base 210 and the guide member 300 move in a second direction under the action of the drive component 400. Compared with the guide member 300 and the housing 110 being directly connected, the second connecting member 120 is set separately to realize the connection between the housing 110 and the guide member 300, which is a more flexible setting method and facilitates maintenance.

[0100] In addition, the first connector 220 and the second connector 120 are both slidably connected to the guide 300, and the first connector 220 is fixedly connected to the base 210 and the second connector 120 is fixedly connected to the housing 110, thereby achieving decoupling of the movement of the movable component 200 relative to the fixed component 100.

[0101] Optionally, the first connector 220 and the second connector 120 can be bushings, making their connection with the L-shaped slide shaft smoother. The L-shaped slide shaft and the bushing cooperate with each other, providing limiting and guiding functions, enabling the movable component 200 to move in a straight line, and achieving decoupling of the movement of the movable component 200.

[0102] In some embodiments of this application, such as Figure 6 and Figure 7 As shown, the number of first connectors 220 and second connectors 120 can both be at least two; at least two first connectors 220 are spaced apart along a first direction; at least two second connectors 120 are spaced apart along a second direction. This arrangement provides at least two connection points in both the first and second directions, which can prevent the guide 300 from shaking with the base 210 or the housing 110, and can make the guiding function of the guide 300 more accurate.

[0103] In some embodiments of this application, such as Figures 6 to 8 As shown, Figure 7 for Figure 5 According to the AA cross-sectional view, the motor also includes a support member 500. The support member 500 is disposed between the fixed component 100 and the movable component 200, and spaced apart from the guide member 300, for jointly supporting the fixed component 100 and the movable component 200 together with the guide member 300. The support member 500 and the guide member 300 provide distributed support points, providing support force during movement, which can prevent overturning caused by the support points between the fixed component 100 and the movable component 200 being too concentrated or uneven. The support member 500 has the function of preventing overturning, which can improve the stability of the anti-shake characteristics. At the same time, the support member 500 and the guide member 300 are arranged in the same layer, which is a single-layer design, which helps to reduce the size of the motor in the optical axis direction.

[0104] In some embodiments of this application, such as Figures 7 to 9 As shown, Figure 9 for Figure 5The exploded structural diagram from a second perspective shows that the movable component 200 has a first receiving groove 211; the fixed component 100 has a second receiving groove 111, which is arranged opposite to the first receiving groove 211; the support member 500 is disposed within the first receiving groove 211 and the second receiving groove 111. The first receiving groove 211 and the second receiving groove 111 limit the support member 500, preventing it from dislodging from between the fixed component 100 and the movable component 200 during movement. Simultaneously, the placement of the support member 500 within the first receiving groove 211 and the second receiving groove 111 helps save space in the motor's optical axis direction, facilitating miniaturization of the motor design.

[0105] Optionally, the support member 500 may be configured to contact the bottom of the first receiving groove 211 and the second receiving groove 111 respectively.

[0106] like Figures 7 to 9 As shown, optionally, the first receiving groove 211 can be formed on the housing 110, and the second receiving groove 111 can be formed on the base 210. The base 210 is also provided with a third receiving groove 213 for receiving the magnet 410 in the drive assembly 400, and the housing 110 is also provided with a fourth receiving groove 113 for receiving the coil 420 in the drive assembly 400. The structure of the drive assembly 400 will be described in detail later. A first recessed structure 214 can be provided on the base 210 at a position corresponding to the guide member 300, and a second recessed structure 114 can be provided on the housing 110 at a position corresponding to the guide member 300. The first recessed structure 214 and the second recessed structure 114 are arranged opposite to each other, providing receiving space for the guide member 300, the first connector 220, and the second connector 120. Figures 10 to 12 As shown, Figure 10 This is a schematic diagram of the motor structure in this embodiment, omitting the housing 110, the magnetic sheet 430, and the second metal sheet 130. Figure 11 for Figure 10 Rear view, Figure 12 for Figure 5 In the rear view, the support 500, guide 300, first connector 220, second connector 120 and drive assembly 400 are all embedded in the base 210 or housing 110, which can reduce the distance between the base 210 and housing 110 and save space for the motor in the optical axis direction.

[0107] Optionally, such as Figure 9 and Figure 10As shown, the movable component 200 has a first through hole 212 at its center; the fixed component 100 has a second through hole 112 at its center; the second through hole 112 corresponds to the first through hole 212; the guide member 300 is disposed at the edge of the movable component 200 and the fixed component 100; the guide member 300, the drive component 400, and the first through hole 212 and the second through hole 112 are spaced apart. This arrangement... Figure 4 The lens 31 can be disposed within the first through hole 212 and the second through hole 112, and connected to the base 210. The base 210 drives the lens 31 to move to achieve optical image stabilization. The guide member 300 is disposed at the edge and does not occupy the space of the lens 31. Specifically, the first through hole 212 can be formed on the base 210, and the second through hole 112 can be formed on the housing 110. The base 210 and the housing 110 can be rectangular. The motor is not a symmetrical structure, but adopts an eccentric structure design, which is conducive to the miniaturization of the motor size and improves the space utilization of the camera module 30.

[0108] In some embodiments of this application, reference is returned. Figure 8 and Figure 9 The first receiving groove 211 may contain a first metal sheet 230 (Enhance Yoke); the second receiving groove 111 may contain a second metal sheet 130 (Enhance Yoke); the support member 500 may be a ball bearing 510 (Ceramic Ball), which is in rolling connection with the first metal sheet 230 and the second metal sheet 130. The ball bearing 510 is spherical and has high pressure resistance. The arrangement of the first metal sheet 230 and the second metal sheet 130 ensures that the surfaces of the movable component 200 and the fixed component 100 that contact the ball bearing 510 are both flat metal surfaces. The high rigidity of the flat metal surfaces reduces the risk of dents. Simultaneously, the flat ball bearing 510 also reduces frictional resistance, making the movement of the movable component 200 smoother and improving the stability of the anti-shake characteristics.

[0109] Optionally, the base 210 and the housing 110 can be made of plastic; the first metal sheet 230 is fixedly connected to the base 210 by injection molding, and the second metal sheet 130 is fixedly connected to the housing 110 by injection molding; the injection molding connection method has high reliability and can directly fix the base 210 and the housing 110 to the first metal sheet 230 and the second metal sheet 130 during the preparation of the base 210 and the housing 110 without additional fixing steps, which helps to improve production efficiency.

[0110] In other embodiments of this application, the support member 500 may also be a support column or a support block, etc., and this application does not limit it in this way.

[0111] like Figures 7 to 9As shown, the first receiving groove 211 and the second receiving groove 111 are circular grooves. During the movement of the movable component 200, the ball 510 rolls in the first receiving groove 211 and the second receiving groove 111. The circular shape of the first receiving groove 211 and the second receiving groove 111 can prevent the ball 510 from making sharp corner contact with the side walls of the first receiving groove 211 and the second receiving groove 111, making the ball 510 less prone to damage and helping to improve the service life of the motor.

[0112] In other embodiments of this application, the first receiving groove 211 and the second receiving groove 111 may also be elliptical grooves or square grooves, etc., and this application does not limit them.

[0113] In some embodiments of this application, such as Figure 9 and Figure 10 As shown, the drive assembly 400 includes at least two magnets 410 and at least two coils 420. The at least two magnets 410 are fixedly connected to the movable assembly 200. The at least two coils 420 are fixedly connected to the fixed assembly 100 and are arranged opposite to the at least two magnets 410 in the optical axis direction. The coils 420 are configured to generate an interaction force with the oppositely arranged magnets 410 in a first direction or a second direction when energized. Since the coils 420 and the fixed assembly 100 are fixedly connected, and the magnets 410 and the movable assembly 200 are fixedly connected, the direction of the interaction force between the magnets 410 and the coils 420 can be controlled by controlling the energization of the coils 420, so that the magnets 410, under the force of the coils 420, drive the movable assembly 200 to move in the first direction or the second direction.

[0114] Optionally, the magnet 410 can be fixedly connected to the base 210 by adhesive bonding; the coil 420 can be fixedly connected to the housing 110 by adhesive bonding.

[0115] In some embodiments of this application, such as Figure 13 and Figure 14 As shown, Figure 13 This is a schematic diagram of the motor structure in this embodiment, omitting the housing 110 and the magnetic sheet 430. Figure 14The diagram illustrates the interaction force pattern between the coil 420 and the magnet 410 in this embodiment. At least two magnets 410 include a first magnet 411 and a second magnet 412. The first magnet 411 has its N and S poles distributed along a first direction; the second magnet 412 has its N and S poles distributed along a second direction. The N and S poles of the first magnet 411, distributed along the first direction, generate an interaction force with the coil 420 in that direction, causing the movable component 200 to move together with the first magnet 411 along the first direction. The N and S poles of the second magnet 412, distributed along the second direction, generate an interaction force with the coil 420 in that direction, causing the movable component 200 to move together with the magnet 410 along the second direction.

[0116] The following is based on Figure 14 Taking the arrangement shown as an example, the motion principle of the motor in this embodiment of the application will be explained.

[0117] The N and S poles of the first magnet 411 and the second magnet 412 are arranged as follows: Figure 14 As shown, the coil 420 corresponding to the first magnet 411 is the first coil 421, and the coil 420 corresponding to the second magnet 412 is the second coil 422. When a clockwise current is applied to the coil 420, the first magnet 411 and the first coil 421 generate an interaction force in the first direction. The force on the first coil 421 is to the right, and the force on the first magnet 411 is to the left. Since the fixed component 100 is stationary, the first coil 421 is fixedly connected to the fixed component 100 and cannot move. The first magnet 411 drives the movable component 200 fixedly connected to it to move to the left, in the following direction: Figure 14 The direction indicated by the hollow arrow next to the first magnet 411; at the same time, since the first connector 220 is fixedly connected to the base 210 and the second connector 120 is fixedly connected to the housing 110, the second connector 120 has a limiting effect on the movement of the guide 300 in the first direction, so that the guide 300 cannot move in the first direction, then the first connector 220 drives the base 210 to slide along the first part 310 of the guide 300.

[0118] When a clockwise current is applied to coil 420, the second magnet 412 and the second coil 422 generate an interaction force in the second direction. The force on the second coil 422 is upward, and the force on the magnet 410 is downward. Since the fixed component 100 is stationary, the second coil 422 is fixedly connected to the fixed component 100 and cannot move. The second magnet 412 drives the movable component 200 fixedly connected to it to move downward, in the following direction: Figure 14The direction indicated by the hollow arrow next to the second magnet 412; at the same time, since the first connector 220 is fixedly connected to the base 210 and the second connector 120 is fixedly connected to the housing 110, the first connector 220 has a limiting effect on the movement of the guide 300 along the second direction, so that the guide 300 moves along the second direction with the first connector 220 and the base 210, and the second connector 120 slides relative to the second part 320 of the guide 300.

[0119] It should be noted that the terms "up," "down," "left," and "right" used here all refer to... Figure 14 The directions corresponding to "up", "down", "left" and "right" may change under other perspectives, so please confirm according to the actual situation.

[0120] Optionally, such as Figure 14 As shown, at least two magnets 410 and at least two coils 420 are disposed on both sides of the first through hole 212 and the second through hole 112; this arrangement saves more space and allows the force on the movable component 200 to be more even. Optionally, the first coil 421 and the second coil 422 can have the same structure and be arranged perpendicular to each other to provide driving force in the first OIS direction and the second OIS direction.

[0121] In some embodiments of this application, such as Figure 14 As shown, the motor also includes a sensor 600; the sensor 600 is configured in a one-to-one correspondence with the coil 420; the sensor 600 is located between the fixed component 100 and the magnet 410, and is surrounded by the coil 420. By designing the sensor 600 at the center of the coil 420, the sensor 600 senses changes in magnetic flux, and adjusts and corrects the position of the lens 31, resulting in better image stabilization.

[0122] Optionally, the sensor 600 can be a Hall sensor or a TMR sensor (Tunnel MagnetoResistance Sensor). The coil 420 and magnet 410, combined with the position feedback from the Hall sensor or TMR sensor, can achieve precise control of the lens 31's image stabilization position, improving the user experience. The type of sensor 600 corresponding to different coils 420 can be the same or different; this application does not limit this. The sensor 600 can be adhesively fixed to the housing 110.

[0123] In some embodiments of this application, reference is returned. Figure 9The drive assembly 400 also includes a magnetic sheet 430; the magnetic sheet 430 is disposed opposite to the magnet 410, located between the fixed assembly 100 and the coil 420, and is fixedly connected to the fixed assembly 100. The magnetic sheet 430 can concentrate and confine the magnetic field of the magnet 410, thereby improving the efficiency of the motor. At the same time, the magnet 410 has a magnetic attraction to the magnetic sheet 430. The two are disposed opposite to each other, and the magnetic attraction causes the movable assembly 200 to press the guide member 300 (L-shaped sliding shaft) and the support member 500 (ball bearing 510), providing the reaction force required for guidance and movement.

[0124] In this embodiment of the motor, the drive component 400 cooperates with the guide component 300, so that the movable component 200 moves relative to the fixed component 100 along a first direction or a second direction under the drive of the drive component 400 and the guidance of the guide component 300; that is, when the movable component 200 moves along the first direction, it does not move in the second direction, and when it moves along the second direction, it does not move in the first direction, thus achieving decoupling of the movement of the movable component 200, so that the movement of the movable component 200 in the first direction and the second direction do not affect each other, avoiding the problem of rotation and crosstalk that easily occurs when the motor performs image stabilization in different directions in related technologies, thereby improving the imaging quality and achieving a decoupled optical image stabilization effect. Meanwhile, since the guide 300 and the support 500 are set on the same layer, both located between the movable component 200 and the fixed component 100, they can provide support. Furthermore, the guide 300, the first connector 220, the second connector 120, and the drive component 400 are all set by embedding them into the base 210 or the housing 110, which reduces the thickness of the motor in the optical axis direction and facilitates the miniaturization of the motor. This allows for the driving of large-aperture / high-mass lenses with better optical performance to achieve optical image stabilization within a smaller size, ensuring higher performance within the same space.

[0125] The motors in this application embodiment are particularly suitable for electronic products that need to drive large-mass optical devices to achieve long-stroke optical image stabilization photography functions; they are also suitable for closed-loop optical image stabilization motors for electronic device cameras, as well as other similar application scenarios.

[0126] The camera module 30 of this application embodiment includes a lens 31 and a motor of any of the above embodiments. The driving component 400 of the motor cooperates with the guide 300, so that the movable component 200 moves relative to the fixed component 100 in a first direction or a second direction under the drive of the driving component 400 and the guidance of the guide 300. That is, when the movable component 200 moves in the first direction, it does not move in the second direction, and when it moves in the second direction, it does not move in the first direction. This achieves decoupling of the movement of the movable component 200, so that the movement of the movable component 200 in the first direction and the second direction do not affect each other. This avoids the problem of rotation and crosstalk that easily occurs when the motor performs image stabilization in different directions in related technologies, thereby improving the image quality and achieving a decoupled optical image stabilization effect.

[0127] The electronic device of this application embodiment includes a camera module 30 of any of the above embodiments. The motor in the camera module 30 decouples the movement of the movable component 200, so that the movement of the movable component 200 in the first direction and the second direction does not affect each other. This avoids the problem of rotation and crosstalk that the motor is prone to when performing image stabilization in different directions in the related art, thereby improving the image quality and achieving the decoupled optical image stabilization effect, thereby improving the image quality of the electronic device.
