Description

Technical Field

[0001] This application relates to the field of shooting equipment technology, specifically the design of a motor, a camera module, and an electronic device. Background Technology

[0002] With the widespread adoption and development of smartphones, mobile phone photography has become a common way for people to take pictures, and phones with optical zoom or focusing functions are increasingly popular among users. Typically, the camera module in a mobile phone uses a magnet and a coil to generate Lorentz force, driving the movement of a lens array to achieve optical zoom or focusing. However, when the coil is energized, the magnetic effect of the current generates a magnetic push / attraction force on the magnet, causing the lens array to tip over and affecting the use of the camera module. Summary of the Invention

[0003] This application provides a motor, a camera module, and an electronic device. The motor includes a base, a carrier, a first coil, a second coil, a first magnetic component, and a second magnetic component. Through the design of the coil and the magnetic component, the magnetic force exerted on the first magnetic component by the first coil is opposite in direction to the magnetic force exerted on the second magnetic component by the second coil, thereby reducing the magnetic interference of the coil on the magnetic component and facilitating the balance of the carrier.

[0004] In a first aspect, this application provides a motor. The motor includes a base, a carrier, a first coil, a second coil, a first magnetic element, and a second magnetic element; the base includes a connected bottom and a first side portion, the first side portion and the bottom portion being arranged at an angle; the carrier is connected to the base, and the carrier can move relative to the base along a first direction; the first coil and the second coil are both mounted on the first side portion, and the first coil and the second coil are arranged in the first direction; the first magnetic element and the second magnetic element are both mounted on the side of the carrier near the first side portion, the first magnetic element and the first coil are facing each other, the second magnetic element and the second coil are facing each other, and both the first magnetic element and the second magnetic element are Heilbeck magnets; the first magnetic element includes a first magnet and a second magnet arranged in the first direction, the first magnet and the second magnet both having magnetic pole faces facing the first coil, and the polarity directions of the first magnet and the second magnet are opposite; the second magnetic element includes a third magnet and a fourth magnet arranged in the first direction, the polarity direction of the third magnet is opposite to the polarity direction of the first magnet, and the polarity direction of the fourth magnet is opposite to the polarity direction of the second magnet.

[0005] In this application, since both the first and second magnetic components are Heilbeck magnets, the first and second magnetic components can generate a stronger magnetic field under the same size, thereby increasing the Lorentz force generated by the interaction between the driving magnet and the driving coil, and thus increasing the driving force of the driving coil to drive the carrier to move relative to the base, which helps to make up for the problem of insufficient power of the motor driving on one side.

[0006] In this application, by controlling the directions of the current flowing through the first coil and the second coil to be opposite, the force generated by the first coil and acting on the first magnetic component due to the magnetic effect of the current is opposite in direction to the force generated by the second coil and acting on the second magnetic component. This reduces or even eliminates the pushing or attracting force of the drive coil on the drive magnet, thereby reducing or even avoiding the risk of the drive coil causing the carrier to tip over. Specifically, due to the magnet arrangement characteristics in the Helbeck magnet, when the directions of the current flowing through the first coil and the second coil are opposite, the interaction between the first coil and the first magnetic component generates a Lorentz force parallel to the first direction. Since the first coil is fixed to the base, the first magnetic component experiences a force in the opposite direction. Similarly, the interaction between the second coil and the second magnet generates a Lorentz force parallel to the first direction. Since the second coil is fixed to the base, the second magnetic component experiences a force in the opposite direction, and the two forces are in the same direction.

[0007] In some possible implementations, the first coil includes a first long side, a first short side, a second long side, and a second short side connected end to end, with the first long side facing the first magnet and the second long side facing the second magnet; and / or, the second coil includes a third long side, a third short side, a fourth long side, and a fourth short side connected end to end, with the third long side facing the third magnet and the fourth long side facing the fourth magnet.

[0008] In this implementation, by aligning the first long side with the first magnet and the second long side with the second magnet, the magnetic field interaction between the first coil and the first magnetic component after energization is enhanced, thereby increasing the magnitude of the Lorentz force and thus the driving force on the first magnetic component. Similarly, by aligning the third long side with the third magnet and the fourth long side with the fourth magnet, the magnetic field interaction between the second coil and the second magnetic component after energization is enhanced, thereby increasing the magnitude of the Lorentz force and thus the driving force on the second magnetic component.

[0009] In some possible implementations, the first magnet has a first magnetization direction and a first polarity direction, which are set at a non-90° angle; the second magnet has a second magnetization direction and a second polarity direction, which are set at a non-90° angle; and the components of the first magnetization direction in the first direction and the components of the second magnetization direction in the first direction point in the same direction.

[0010] In this implementation, since the first magnetization direction of the first magnet is deviated from the center of the first magnetic element, the magnetic field lines of the N pole face of the first magnet pointing towards the S pole face of the second magnet are squeezed toward the center of the first magnetic element, thereby increasing the magnetic flux density on one side of the first magnetic element, and thus increasing the magnetic flux density perpendicular to the first coil. When the first coil is energized, the first magnetic element can generate a larger Lorentz force in the first coil, which is beneficial to provide a stronger driving force.

[0011] In some possible implementations, the third magnet has a third magnetization direction and a third polarity direction, which are set at a non-90° angle; the fourth magnet has a fourth magnetization direction and a fourth polarity direction, which are set at a non-90° angle; and the components of the third magnetization direction in the first direction and the components of the fourth magnetization direction in the first direction point in the same direction.

[0012] In this implementation, since the third magnetization direction of the fourth magnet is offset from the center of the second magnetic element, the magnetic field lines of the N pole of the fourth magnet pointing towards the S pole of the third magnet are squeezed toward the center of the second magnetic element, thereby increasing the magnetic flux density on one side of the second magnetic element, and thus increasing the magnetic flux density perpendicular to the second coil. When the second coil is energized, the second magnetic element can generate a larger Lorentz force in the second coil, which is beneficial to provide a stronger driving force.

[0013] In some possible implementations, the first magnetic element further includes a fifth magnet located between the first and second magnets, the polarity of which is different from that of the first and second magnets; and / or, the second magnetic element further includes a sixth magnet located between the third and fourth magnets, the polarity of which is different from that of the third and fourth magnets.

[0014] In this implementation, the fifth magnet in the first magnetic component guides the magnetic fields of the first and second magnets, thus enhancing the magnetic field exerted by the first magnetic component on the first coil. Similarly, the sixth magnet in the second magnetic component guides the magnetic fields of the third and fourth magnets, further enhancing the magnetic field exerted by the second magnetic component on the second coil.

[0015] In some possible implementations, the first magnetic element further includes a fifth magnet and a seventh magnet, both of which are located between the first magnet and the second magnet. The fifth magnet is closer to the first magnet than the seventh magnet. The polarity of the fifth magnet is the same as that of the first magnet, and the polarity of the seventh magnet is the same as that of the second magnet.

[0016] In this implementation, by increasing the number of magnets, the magnetic field strength of the first magnetic component can be enhanced, thereby increasing the Lorentz force generated by the combined action of the first magnetic component and the first coil, and thus increasing the driving force of the drive assembly.

[0017] In some possible implementations, the second magnetic element also includes a sixth magnet and an eighth magnet, both of which are located between the third magnet and the fourth magnet. The sixth magnet is closer to the third magnet than the eighth magnet. The polarity of the sixth magnet is the same as that of the third magnet, and the polarity of the eighth magnet is the same as that of the fourth magnet.

[0018] In this implementation, by increasing the number of magnets, the magnetic field strength of the second magnetic component can be enhanced, thereby increasing the Lorentz force generated by the combined action of the second magnetic component and the second coil, and thus increasing the driving force of the drive assembly.

[0019] In some possible implementations, the fifth magnet has a fifth magnetization direction and a fifth polarization direction, which are set at a non-90° angle to each other, and / or the seventh magnet has a seventh magnetization direction and a seventh polarization direction, which are set at a non-90° angle to each other.

[0020] In this implementation, the N-pole of the fifth magnet faces the same direction as the N-pole of the first magnet. This allows the fifth magnet to work with the first magnet to provide a magnetic field perpendicular to the first coil. Furthermore, the fifth magnet enhances the compression effect of the magnetic field lines of the first magnet, thereby further increasing the magnetic flux density of the first magnetic component on the first coil side, and consequently increasing the Lorentz force generated by the interaction between the first magnetic component and the first coil. Similarly, the seventh and second magnets also enhance the Lorentz force generated by the interaction between the first magnetic component and the first coil.

[0021] In some possible implementations, the sixth magnet has a sixth magnetization direction and a sixth polarization direction, which are set at a non-90° angle to each other, and / or the eighth magnet has an eighth magnetization direction and an eighth polarization direction, which are set at a non-90° angle to each other.

[0022] In this implementation, the S-pole face of the sixth magnet faces the same direction as the S-pole face of the third magnet. This allows the sixth magnet to work with the third magnet to provide a magnetic field perpendicular to the first coil. Furthermore, the sixth magnet enhances the squeezing effect of the magnetic field lines of the third magnet, thereby further increasing the magnetic flux density of the second magnetic component on the second coil side, and consequently increasing the Lorentz force generated by the combined action of the second magnetic component and the second coil. Similarly, the eighth and fourth magnets also enhance the Lorentz force generated by the combined action of the second magnetic component and the second coil.

[0023] In some possible implementations, the first magnetic component and the second magnetic component are separate structures, so that the combination of the first magnetic component and the second magnetic component is more flexible.

[0024] In some other possible implementations, the first magnetic component and the second magnetic component are integrated into one structure, which facilitates the installation of the first magnetic component and the second magnetic component.

[0025] In some possible implementations, the second and third magnets are separate structures, which allows for flexible arrangement of the second and third magnets.

[0026] In some other possible implementations, the second and third magnets are integrated into a single structure.

[0027] In this implementation, since the polarity directions of the second magnet and the third magnet are the same, designing the second magnet and the third magnet as an integral structure helps to avoid the mutual repulsion between the second magnet and the third magnet, thus facilitating installation.

[0028] In some possible implementations, the motor also includes a housing and a first shielding plate. The housing is connected to the base to enclose and form a receiving space. The receiving space houses the carrier, the first coil, the second coil, the first magnetic element, the second magnetic element, and the first shielding plate. The first shielding plate is located on the side of the first coil and the second coil away from the first magnetic element and the second magnetic element.

[0029] In this implementation, the first shielding plate can be positioned facing the drive coil to shield it, thereby reducing the noise generated when the drive coil is operating. By designing the first shielding plate, the first and second coils can be shielded, reducing the noise from the first and second coils after they are energized from passing through the housing, thus reducing the background noise and consequently reducing the noise generated during motor operation.

[0030] In some possible implementations, the orthographic projections of the first coil and the second coil onto the first shielding plate fall within the shielding plate, so that the first shielding plate can better shield and cover the first coil and the second coil, which is beneficial to improving the effect of shielding the noise generated by the operation of the first coil and the second coil.

[0031] In some possible implementations, the thickness of the first shielding plate is greater than or equal to 0.25 mm.

[0032] In this implementation, since the motor adopts a single-sided drive method, the driving force required on one side is higher, which causes the first coil and the second coil to generate more noise when they are working. By designing the thickness of the first shielding plate to meet the above dimensions, the noise generated by the first coil and the second coil can be effectively shielded.

[0033] The design of the first shielding plate can reduce the noise generated by the motor to less than or equal to decibels, thereby improving the quietness of the motor operation and enhancing the user experience of camera modules and electronic devices.

[0034] In some possible implementations, the first side portion includes a first support plate and a second support plate arranged in a first direction, with the first support plate and the second support plate spaced apart. The first coil and the second coil are both located between the first support plate and the second support plate. The first shielding plate is located between the first side portion and the inner wall of the outer shell, and the first shielding plate covers the gap between the first support plate and the second support plate in the first direction.

[0035] In this implementation, the first shielding plate covers the gap between the first support plate and the second support plate in the first direction, so that the first shielding plate, the first support plate, the second support plate, the first carrier and the bottom can enclose and form a space to accommodate the first coil and the second coil. In terms of spatial design, it can form a wrapping effect on the first coil and the second coil, which is beneficial to improving the shielding effect on the noise generated by the operation of the first coil and the second coil.

[0036] In some possible implementations, at least a portion of the first coil and the second coil are embedded within the first side portion.

[0037] In this implementation, the first coil and the second coil can be integrally formed with the first side portion through injection molding to improve the installation stability of the first coil and the second coil. Since the first side portion can reinforce the installation of the first coil and the second coil, and can cover at least a portion of the first coil and the second coil, the vibration generated by the first coil and the second coil during operation is reduced, which helps to reduce the noise generated by the first coil and the second coil during operation. Therefore, the first shielding plate does not need to be designed to be very thick to achieve the expected noise shielding effect.

[0038] In some possible implementations, the motor also includes a position detection component, which includes a magnetic grating and a tunnel magnetoresistive sensor; the magnetic grating is mounted on the carrier and extends along a first direction, the tunnel magnetoresistive sensor is mounted on the base, and the position detection component is used to detect the position of the tunnel magnetoresistive sensor relative to the magnetic grating in order to detect the position of the carrier relative to the base.

[0039] In this implementation, the position detection component can detect the position of the carrier relative to the base by sensing the position of the tunnel magnetoresistive sensor relative to the magnetic grating. This helps the auxiliary drive component to drive the carrier's movement. By feeding back the carrier's position, the movement accuracy of the carrier is improved, thereby improving the quality of the camera module's optical zoom / focus.

[0040] In this implementation, due to the installation of the tunnel magnetoresistive sensor and the magnetic grating, during the movement of the carrier relative to the base along the first direction, the tunnel magnetoresistive sensor can detect the position of the tunnel magnetoresistive sensor relative to the magnetic grating by sensing the change in the magnetic field of the magnetic grating, thereby detecting the position of the carrier relative to the base, improving the position detection accuracy of the carrier, and helping to improve the quality of optical zoom / focusing of the camera module.

[0041] In some possible implementations, the carrier includes a first carrier, a second carrier, a third carrier, and a fourth carrier connected end to end in sequence. The first carrier is closer to the first side relative to the third carrier. A first magnetic component and a second magnetic component are installed on the side of the first carrier facing away from the third carrier. A magnetic grating is installed on the first carrier.

[0042] In this implementation, since the magnetic grating is installed on the first carrier, the tunnel magnetoresistive sensor and the circuit board are both located close to the magnetic grating, so that the tunnel magnetoresistive sensor, the magnetic grating, the driving magnet and the driving coil are concentrated near the first side of the carrier. This allows the tunnel magnetoresistive sensor and the magnetic grating to be kept away from external magnetic interference sources on the side of the second side of the motor facing away from the first side, which helps to reduce the risk of magnetic interference to the tunnel magnetoresistive sensor and the magnetic grating.

[0043] In some possible implementations, the motor also includes a second shielding plate, which includes a first sub-plate and a second sub-plate, connected in an L-shape; the second shielding plate is installed on the bottom side of the first carrier, the magnetic grating is installed on the second shielding plate, the first sub-plate is located between the magnetic grating and the first magnetic element and the second magnetic element, the second sub-plate is located between the magnetic grating and the coil, and the tunnel magnetoresistive sensor is installed at the bottom.

[0044] In this implementation, the first sub-board can be located between the magnetic grating and the first and second magnetic components to reduce magnetic field interference between the magnetic grating and the first and second magnetic components. The second sub-board can be located on the side of the magnetic grating facing away from the third carrier to shield the magnetic fields of the first and second magnetic components, thereby reducing magnetic field interference of the first and second magnetic components on the magnetic grating.

[0045] In this implementation, the second sub-board of the second shielding plate can be located between the magnetic grating and the driving coil, so that the second sub-board can isolate the magnetic grating and the driving coil, reduce the magnetic field interference between the driving coil and the magnetic grating after the driving coil is energized, and improve the stability of the position detection of the position detection component.

[0046] In some possible implementations, the motor further includes a first connector and a second connector, which are spaced apart. Both the first connector and the second connector are used to connect the carrier and the base. The first connector is a sliding shaft, a spring, a suspension wire, or a ball bearing. And / or, the second connector is a sliding shaft, a spring, a suspension wire, or a ball bearing.

[0047] In this implementation, by setting the first and second connecting members as sliding shafts and respectively disposed within the first and second sliding grooves, the stability of the carrier moving relative to the base along the first direction is improved. When the first and second connecting members are springs or suspension wires, the carrier does not need to be provided with the first and second sliding grooves. Furthermore, the springs or suspension wires can not only guide the movement of the carrier, but also limit the movement stroke of the carrier through their elasticity.

[0048] In some possible implementations, the first side portion includes a first support plate and a second support plate arranged in a first direction, with the first support plate and the second support plate spaced apart. The base also includes a second side portion, which is arranged opposite to the first side portion and connected to the bottom. The second side portion includes a third support plate, a connecting plate, and a fourth support plate arranged in the first direction, with the connecting plate connecting between the third support plate and the fourth support plate. The carrier includes a first carrier portion, a second carrier portion, a third carrier portion, and a fourth carrier portion connected end to end in sequence. The first carrier portion is equipped with a first magnetic component and a second magnetic component. At least a portion of the first carrier portion is located between the first support plate and the second support plate. The second carrier portion is closer to the bottom than the fourth carrier portion. At least a portion of the third carrier portion is located between the third support plate and the fourth support plate.

[0049] In this implementation, by installing at least a portion of the first carrier between the first support plate and the second support plate, and installing at least a portion of the third carrier between the third support plate and the fourth support plate, the extra space occupied by the carrier is reduced, thereby improving space utilization and facilitating the miniaturization design of the motor.

[0050] In some possible implementations, the motor further includes a first connector and a second connector, which are spaced apart. Both the first and second connectors are used to connect the carrier and the base. The first connector is a sliding shaft, and the second connector is a sliding shaft. The second carrier portion is provided with a first sliding groove, or the first carrier portion is provided with a first sliding groove, or the first carrier portion and the second carrier portion enclose each other to form a first sliding groove. The second carrier portion is provided with a second sliding groove, or the third carrier portion is provided with a second sliding groove, or the third carrier portion and the second carrier portion enclose each other to form a second sliding groove. The opening of the first sliding groove faces the bottom, and the extension direction of the first sliding groove is parallel to the first direction. The first connector is installed in the first sliding groove and is located between the carrier and the bottom. The opening of the second sliding groove faces the bottom, and the extension direction of the second sliding groove is parallel to the first direction. The second connector is installed in the second sliding groove and is located between the carrier and the bottom.

[0051] In this implementation, by setting the first connector and the second connector as sliding shafts and respectively set in the first sliding groove and the second sliding groove, it is beneficial to improve the stability of the carrier moving relative to the base in the first direction, thereby improving the quality of optical zoom / focusing of the camera module.

[0052] In some possible implementations, the first groove is a U-shaped groove or an L-shaped groove, and the second groove is a V-shaped groove; or, the first groove is a V-shaped groove, and the second groove is a U-shaped groove or an L-shaped groove.

[0053] In this implementation, since one of the first slide groove and the second slide groove can be a U-shaped groove or an L-shaped groove, and the other can be a V-shaped groove, the stability of the connection between the first slide shaft and the second slide shaft and the carrier can be enhanced, thereby improving the stability of the carrier installed on the base, improving the stability of the carrier moving relative to the base in the first direction, and thus improving the quality of optical zoom / focusing of the camera module.

[0054] In some possible implementations, the motor further includes a first buffer, a second buffer, a third buffer, and a fourth buffer; the first buffer is disposed on the surface of the first carrier facing the first support plate, and / or, the first buffer is disposed on the surface of the first support plate facing the first carrier; the second buffer is disposed on the surface of the first carrier facing the second support plate, and / or, the second buffer is disposed on the surface of the second support plate facing the first carrier; the third buffer is disposed on the surface of the third carrier facing the third support plate, and / or, the third buffer is disposed on the surface of the third support plate facing the third carrier; the fourth buffer is disposed on the surface of the third carrier facing the fourth support plate, and / or, the fourth buffer is disposed on the surface of the fourth support plate facing the third carrier.

[0055] In this implementation, since the two surfaces of the first carrier opposite each other along the first direction can be respectively provided with a first buffer and a second buffer, and the two surfaces of the third carrier opposite each other along the first direction can be respectively provided with a third buffer and a fourth buffer, the first buffer can buffer the collision between the first carrier and the first support plate, the second buffer can buffer the collision between the first carrier and the second support plate, the third buffer can buffer the collision between the third carrier and the third support plate, and the fourth buffer can buffer the collision between the third carrier and the fourth support plate during the movement of the carrier relative to the base along the first direction. This reduces the risk of collision damage between the carrier and the base and helps to improve the service life of the motor.

[0056] In some possible implementations, the motor also includes a balancing assembly that connects the third load to the bottom and is used to generate a force acting on the third load toward the bottom, and / or, the balancing assembly is used to generate a force acting on the bottom toward the third load.

[0057] In this implementation, the first and second magnetic components are installed on the first carrier section, while no magnetic component is installed on the third carrier section. This results in a greater load on the first carrier section than on the third carrier section, which may cause balance disturbances in the carrier's movement. By designing a balancing component, a force can be applied between the third carrier section and the bottom to generate opposing forces between them, thereby pulling the third carrier section towards the bottom, which is equivalent to adding a load to the third carrier section. This balances the loads of the first and third carrier sections. At this time, the pressure between the first carrier section and the first connecting member, and the pressure between the third carrier section and the second connecting member, can be close to or even completely the same. This balances the frictional force experienced by the carrier on the first carrier section side and the frictional force experienced on the third carrier section side during movement, which is beneficial to improving the carrier's movement balance.

[0058] In some possible implementations, the balancing component includes a balancing magnet and a magnetic body, with the balancing magnet and the magnetic body at least partially facing each other, and the balancing magnet attracting the magnetic body; the balancing magnet is mounted on a third carrier, and the magnetic body is mounted on the bottom; or, the balancing magnet is mounted on the bottom, and the magnetic body is mounted on the third carrier.

[0059] In this implementation, by setting a balancing magnet and a magnetic body, the magnetic attraction between them can be used to pull the third carrier towards the bottom, thereby balancing the load of the first and third carriers. Since the balancing magnet and the magnetic body can still generate magnetic attraction even when spaced apart, the design of the balancing magnet and the magnetic body will not cause frictional interference to the movement of the carrier relative to the base.

[0060] In some possible implementations, the balancing component includes an elastic element that connects the third load to the bottom and is in a stretched state.

[0061] In this implementation, because the elastic element is in a stretched state, it can exert its elastic recovery force on the third load and the bottom, generating opposing forces between them to pull the third load towards the bottom, thereby balancing the load of the first and third loads. Furthermore, since the elastic element can deform in various directions, it can be pulled in the first direction when the carrier moves relative to the base, without interfering with the carrier's movement. The elastic element can also limit the carrier's movement relative to the base through its elasticity, confining it within its stroke range, which is beneficial for collision prevention.

[0062] In some possible implementations, the motor is a single-sided drive motor, which drives the first and second magnetic components after being energized by the first and second coils, thereby causing the carrier to move relative to the base.

[0063] In this implementation, since the motor in the camera module is a single-sided drive motor and the drive component is installed on the side of the carrier facing away from the side camera module, the magnetic interference source in the side camera module is far away from the camera module when the drive component is working. This reduces the risk of magnetic interference to the drive component in the camera module, thereby improving the stability of the motor-driven carrier movement and improving the quality of optical zoom / focus achieved by the camera module.

[0064] Secondly, this application provides a camera module. The camera module includes a lens, an image sensor (as described in any of the aforementioned motors), the image sensor being located on the image side of the lens, and at least a portion of the lens being mounted on the carrier of the motor.

[0065] In this application, the smoothness of motor drive is improved by designing the motor, thereby improving the quality of optical zoom / focus achieved by the camera module.

[0066] Thirdly, this application provides an electronic device. The electronic device includes a housing and the aforementioned camera module, with the camera module mounted on the housing.

[0067] In this application, the user experience of electronic devices is improved by enhancing the quality of optical zoom / focus in the camera module.

[0068] In some possible implementations, the electronic device also includes a side-mounted camera module, which is mounted in the housing and located on one side of the second side of the base of the motor in the camera module.

[0069] In this implementation, since the motor in the camera module is a single-sided drive motor and the drive component is installed on the side of the carrier facing away from the side camera module, the magnetic interference source in the side camera module is far away from the camera module when the drive component is working. This reduces the risk of magnetic interference to the drive component in the camera module, thereby improving the stability of the motor-driven carrier movement and improving the quality of optical zoom / focus achieved by the camera module.

[0103] The embodiments of this application are described below with reference to the accompanying drawings.

[0104] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. 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. "Multiple" refers to at least two.

[0105] The directional terms mentioned in the embodiments of this application, such as "upper", "lower", "inner", "outer", "top", "bottom", "side", etc., are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0106] In the embodiments of this application, the relative positional relationships mentioned, such as parallel, perpendicular, and aligned, are defined in relation to the current technological level, rather than being absolutely strict. Slight deviations are permissible; approximations of parallelism, perpendicularity, or alignment are all acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0107] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0108] Please refer to the following: Figure 1A and Figure 1B , Figure 1A This is a schematic diagram of the structure of the electronic device 1000 provided in some embodiments of this application; Figure 1B yes Figure 1A A partial exploded view of the electronic device 1000 shown.

[0109] In some embodiments, the electronic device 1000 can be a mobile phone, tablet personal computer, laptop computer, smart screen, personal digital assistant (PDA), camera, personal computer, laptop computer, in-vehicle equipment, wearable device, augmented reality (AR) glasses, AR helmet, virtual reality (VR) glasses, or VR helmet, or other devices with camera functions. Figure 1A In this embodiment, the electronic device 1000 is a mobile phone as an example for description. Of course, other types of electronic devices 1000 can also adopt a similar structure, which will not be described in detail below.

[0110] Understandable, Figure 1A and Figure 1B The electronic device 1000 is shown only schematically, and the actual shape, size, location, and construction of these components are not subject to change. Figure 1A and Figure 1B The limitations of electronic device 1000 may also include, compared to Figure 1A and Figure 1B More or fewer parts.

[0111] In some embodiments, the electronic device 1000 may include a camera module 100, a screen 200, and a housing 300. The screen 200 is used to display images, videos, etc. The screen 200 may include a light-transmitting panel 2001 and a display screen 2002. The light-transmitting panel 2001 and the display screen 2002 are stacked and fixedly connected. The light-transmitting panel 2001 mainly serves to protect the display screen 2002 from dust. The material of the light-transmitting panel 2001 includes, but is not limited to, glass. The display screen 2002 may be a flexible display screen or a rigid display screen. For example, the display screen 2002 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 micro organic light-emitting diode (MOLED) display screen, a quantum dot light-emitting diode (QLED) display screen, a liquid crystal display (LCD), etc.

[0112] For example, the housing 300 is used to protect the internal electronic components of the electronic device 1000. The housing 300 may include a cover plate 3001, a frame 3002, and a camera decorative element 3003. The cover plate 3001 is located on the side of the display screen 2002 away from the light-transmitting panel 2001, and is stacked with the light-transmitting panel 2001 and the display screen 2002. The frame 3002 is fixed to the cover plate 3001. For example, the frame 3002 can be fixedly connected to the cover plate 3001 by adhesive. The frame 3002 may also be integrally formed with the cover plate 3001, that is, the frame 3002 and the cover plate 3001 are a single structure. The frame 3002 is located between the cover plate 3001 and the light-transmitting panel 2001. The light-transmitting panel 2001 can be fixed to the frame 3002 by adhesive. The light-transmitting panel 2001, the cover plate 3001, and the frame 3002 form an internal accommodating space of the electronic device 1000. The internal space accommodates the display screen 2002. The cover plate 3001 can be made of materials such as metal, plastic, or glass. The cover plate 3001 can be a single-material panel or a panel structure composed of multiple materials and panels. The cover plate 3001 has a mounting opening 3001a, and the camera decorative piece 3003 covers and is fixed to the mounting opening 3001a.

[0113] For example, camera module 100 is used to capture photos / videos. For example, camera module 100 is mounted within housing 300, located within the internal accommodating space of electronic device 1000. Camera module 100 can be used as a rear-facing camera. For example, the light-incident surface of camera module 100 faces camera trim 3003. Camera trim 3003 is used to protect camera module 100.

[0114] In some embodiments, the camera trim 3003 protrudes from the side of the cover plate 3001 away from the light-transmitting panel 2001. This increases the mounting space for the camera module 100 in the thickness direction of the electronic device 1000. In other embodiments, the camera trim 3003 may be flush with the cover plate 3001 or recessed into the internal accommodating space of the electronic device 1000.

[0115] The camera decorative element 3003 has a light-transmitting hole 3003a. The light-transmitting hole 3003a allows light from objects to enter the light-receiving surface of the camera module 100. In some other embodiments, the electronic device 1000 may not include the camera decorative element 3003. In this case, the cover plate 3001 no longer has a mounting opening 3001a, but the light-transmitting hole 3003a is provided on the cover plate 3001, allowing light from objects to enter the light-receiving surface of the camera module 100.

[0116] In some embodiments, the camera module 100 can also be used as a front-facing camera. For example, the light-incident surface of the camera module 100 faces the light-transmitting panel 2001. The display screen 2002 is provided with a light-path obstruction hole. This light-path obstruction hole allows light from the scene to pass through the light-transmitting panel 2001 and then enter the light-incident surface of the camera module 100.

[0117] In other embodiments, the electronic device 1000 may further include one or more other camera modules, illustratively speaking. Figure 1A and Figure 1B The illustrated electronic device 1000 may include two camera modules 100. The two camera modules 100 may be of the same type, for example, both may be periscope cameras. Alternatively, the two camera modules 100 may be of different types, for example, one camera module 100 may be a periscope camera and the other may be a vertical camera; this embodiment does not strictly limit the types.

[0118] The two camera modules 100 can be set side by side and flush (e.g.) Figure 1A and Figure 1B As shown), in some other embodiments, the two camera modules 100 may also be arranged in a staggered manner, that is, one camera module 100 may be closer to the top side of the electronic device 1000 than the other camera module 100.

[0119] When both camera modules 100 are periscope cameras, the optical path refraction directions of the two camera modules 100 can be the same (e.g., Figure 1A and Figure 1B As shown), in some other embodiments, the optical path refraction directions of the two camera modules 100 may not be consistent; for example, the optical path refraction directions of the two camera modules 100 may be opposite, i.e. Figure 1A and Figure 1B One of the two camera modules 100 shown can be rotated 180°.

[0120] It should be noted that, Figure 1A and Figure 1B The number, type, and arrangement of the camera modules 100 shown are for illustrative purposes only and do not limit the design of the camera modules 100 in the electronic device 1000 of this application. In some other embodiments, the electronic device 1000 may include only one camera module 100.

[0121] In some embodiments, such as Figure 1BAs shown, the electronic device 1000 may further include a circuit assembly 400 and an image processor 500. The circuit assembly 400 and the image processor 500 are located within the internal accommodating space of the electronic device 1000. The image processor 500 is fixed to and electrically connected to the circuit assembly 400. The image processor 500 is communicatively connected to the camera module 100. The image processor 500 is used to acquire image data from the camera module 100 and process the image data. The communication connection between the camera module 100 and the image processor 500 may include data transmission via electrical connections such as wiring, or data transmission via coupling or other methods. It is understood that the camera module 100 and the image processor 500 may also achieve a communication connection through other methods capable of data transmission.

[0122] In some embodiments, the electronic device 1000 may further include an analog-to-digital converter (also known as an A / D converter, not shown in the figure). The analog-to-digital converter is connected between the camera module 100 and the image processor 500. The analog-to-digital converter is used to convert the signal generated by the camera module 100 into a digital image signal and transmit it to the image processor 500, whereby the image processor 500 processes the digital image signal and finally displays the image or video on the screen 200.

[0123] In some embodiments, the electronic device 1000 may further include a memory (not shown in the figure), which is communicatively connected to the image processor 500. The image processor 500 processes the digital image signal and then transmits the image to the memory, so that the image can be retrieved from the memory and displayed on the screen 200 at any time when it is needed to view the image later. In some embodiments, the image processor 500 may also compress the processed digital image signal before storing it in the memory to save memory space.

[0124] In some other embodiments, the electronic device 1000 may also not include the screen 200.

[0125] Understandable, Figure 1A and Figure 1B The installation position of the camera module 100 in the illustrated embodiment of the electronic device 100 is merely illustrative, and this application does not strictly limit the installation position of the camera module 100. In some other embodiments, the camera module 100 may also be installed in other locations on the electronic device 1000, such as the upper middle or upper right corner of the back of the electronic device 1000. In some other embodiments, the electronic device 1000 may include a terminal body and an auxiliary component that can rotate, move, or be detached relative to the terminal body, and the camera module 100 may also be disposed on the auxiliary component.

[0126] Please refer to the following: Figures 1A to 2A , Figure 2A yes Figure 1A The electronic device 1000 shown is cut along line AA in some embodiments.

[0127] In some embodiments, the camera module 100 may include a motor 20, an optical path folding element 30, a lens 40, and an image sensor 50. The optical path folding element 30, the lens 40, and the image sensor 50 may be arranged sequentially along the optical axis. At least a portion of the lens in the lens 40 may be mounted within the motor 20, which can drive the lens 40 to move along the optical axis to achieve focusing or zooming. It should be noted that... Figure 2A The dotted line with an arrow indicates the direction of optical transmission.

[0128] For ease of description, a coordinate system is defined, wherein the direction in which the motor 20 drives the lens 40 to move is defined as the X-axis direction, also known as the first direction X; the direction in which light rays are incident from the outside to the optical path deflection element 30 is defined as the Z-axis direction, also known as the second direction Z; and the direction perpendicular to both the X-axis and Z-axis directions is defined as the Y-axis direction, also known as the third direction Y. It should be noted that the coordinate system defined in this embodiment is only used to illustrate the relative positions between the various figures. In other embodiments, the coordinate system may be defined in other ways, which are not limited here.

[0129] In this embodiment, the optical path folding element 30 is used to fold the light rays incident along the second direction Z to be transmitted along the first direction X, so that the light rays can pass through the lens 40 and be incident on the image sensor 50. The optical path folding element 30 plays the role of optical path folding, thereby reducing the length of the camera module 100 and facilitating the miniaturization of the camera module 100.

[0130] For example, the optical path reversing element 30 can be a prism, a mirror, a combination of a prism and a lens, or a combination of a mirror and a lens, etc. In some other embodiments, the camera module 100 may not include the optical path reversing element 30. In this case, the optical axis direction of the lens 40 is the direction of light incidence, and the camera module 100 is a vertical camera.

[0131] In some embodiments, the camera module 100 may also include a rear prism (not shown in the figure), which may be located between the lens 40 and the image sensor 50. The rear prism is used to fold the optical path to further reduce the overall length of the camera module 100, which is beneficial for miniaturization of the camera module 100. In addition, due to the arrangement of the rear prism, the image sensor 50 is tilted, thereby reducing the height of the image sensor 50 in the camera module 100, which is beneficial for reducing the shoulder height of the camera module 100, thus facilitating the thinner and lighter design of the camera module 100.

[0132] Please refer to the following: Figure 2Aand Figure 2B , Figure 2B yes Figure 1A An example diagram showing the relative positions of the two camera modules 100 in some embodiments of the electronic device 1000. It should be noted that, for ease of description, in the following text, Figure 2B The camera module 100 on the right side is called camera module 100, and the camera module 100 on the right side is called side camera module 600. The term "side" only refers to the camera module 100 located next to the left camera module 100, and does not contain any other meaning or functional description.

[0133] In some embodiments, the motor 20 may include a base 1, a carrier 2, and a drive assembly 3. The drive assembly 3 may be mounted on the side of the carrier 2 facing away from the side-mounted camera module 600. The drive assembly 3 may include a drive coil 31 and a drive magnet 32, which are positioned opposite each other. The drive magnet 32 ​​and the drive coil 31 may be mounted on the carrier 2. The motor 20 may be a single-sided drive motor 20, which drives the drive magnet 32 ​​to move the carrier 2 relative to the base 1 along a first direction X after the drive coil 31 is energized.

[0134] In this embodiment, since the motor 20 in the camera module 100 is a single-sided drive motor 20, and the drive component 3 is installed on the side of the carrier 2 facing away from the side camera module 600, when the drive component 3 is working, the magnetic interference source in the side camera module 600 that affects the camera module 100 is far away, reducing the risk of magnetic interference to the drive component 3 in the camera module 100, thereby improving the stability of the motor 20 driving the carrier 2, which is beneficial to improving the quality of optical zoom / focus achieved by the camera module 100.

[0135] In some examples, the side-mounted camera module 600 may include a first driving component 6001, a second driving component 6002, and a side-mounted carrier 6003. The first driving component 6001 and the second driving component 6002 may be mounted on opposite sides of the side-mounted carrier 6003. In this embodiment, since the driving component 3 in the camera module 100 is mounted on the side of the carrier 2 facing away from the side-mounted camera module 600, the magnetic interference of the driving component 3 on the side-mounted camera module 600 is also relatively small. Therefore, the first driving component 6001 and the second driving component 6002 can be mounted on opposite sides of the side-mounted carrier 6003 respectively, which is beneficial to improving the magnetic drive capability of the side-mounted camera module 600.

[0136] In other examples, the side-mounted camera module 600 may only include the first drive component 6001, which may be mounted on the side of the side-mounted carrier 6003 facing away from the camera module 100. That is, the side-mounted camera module 600 also drives the side-mounted carrier 6003 through a single-sided drive. In this embodiment, due to the drive design of the side-mounted camera module 600, the distance between the magnetic interference source in the side-mounted camera module 600 and the drive component 3 in the camera module 100 is further increased, further reducing the risk of magnetic interference to the drive component 3 in the camera module 100. This improves the smoothness of the movement of the carrier 2 driven by the motor 20, which is beneficial for improving the quality of optical zoom / focus achieved by the camera module 100.

[0137] It should be noted that the magnetic interference source of the driving component 3 of the side camera module 100 in the side camera module 600 can also be the image stabilization driving component (not shown in the figure), circuit components, etc., and is not limited here.

[0138] It should be noted that the relative positions of the side camera module 600 and the camera module 100 are only schematic. In some other embodiments, the side camera module 600 may also be mounted in other postures relative to the camera module 100, which is not limited here.

[0139] Please refer to the following: Figure 3 and Figure 4 , Figure 3 yes Figure 2B A schematic diagram of the motor 20 in some embodiments of the camera module 100 shown; Figure 4 yes Figure 3 The diagram shows a partial structural exploded view of the motor 20 in some embodiments.

[0140] Understandable, Figure 3 and Figure 4 The motor 20 is shown only schematically, and the actual shape, size, location, and construction of these components are not subject to change. Figure 3 and Figure 4 Due to limitations, motor 20 can also include, compared to Figure 3 and Figure 4 More or fewer parts.

[0141] In some embodiments, the motor 20 may further include a first connector 4a, a second connector 4b, a first circuit board 5, a position detection component 6, a first shielding plate 7, a second shielding plate 8, a magnetic conductive plate 9, and a housing 10. The drive coil 31 may include a first coil 311 and a second coil 312, and the drive magnet 32 ​​may include a first magnetic element 321 and a second magnetic element 322.

[0142] For example, the outer shell 10 can be connected to the base 1 to enclose and form a receiving space 14. The receiving space 14 can accommodate the carrier 2, the first connector 4a, the second connector 4b, the first circuit board 5, the position detection component 6, the first shielding plate 7, the second shielding plate 8, the magnetic plate 9, and the drive component 3.

[0143] For example, the carrier 2 can be connected to the base 1 via the first connector 4a and the second connector 4b, and the drive assembly 3 can drive the carrier 2 to move relative to the base 1 in the first direction X via the first connector 4a and the second connector 4b.

[0144] For example, the drive coil 31 can be installed on the base 1, and the drive magnet 32 ​​can be installed on the carrier 2. When the drive coil 31 is energized, it interacts with the drive magnet 32 ​​to generate a Lorentz force, which drives the drive magnet 32 ​​to move the carrier 2.

[0145] For example, the first shielding plate 7 can be located on the side of the drive coil 31 that is away from the drive magnet 32. The first shielding plate 7 can be arranged facing the drive coil 31 to shield the drive coil 31, thereby reducing the noise generated when the drive coil 31 is working.

[0146] For example, the magnetic plate 9 can be equipped with a driving magnet 32 ​​to improve the directivity of the magnetic field of the driving magnet 32, which is beneficial to increasing the magnitude of the Lorentz force generated by the interaction between the driving magnet 32 ​​and the driving coil 31.

[0147] For example, the position detection component 6 may include a magnetic grating 61 and a tunnel magnetoresistive (TMR) sensor. The magnetic grating 61 may be mounted on the carrier 2, and the tunnel magnetoresistive sensor 62 may be mounted on the first circuit board 5, which in turn may be mounted on the carrier 2. In this embodiment, the position detection component 6 can detect the position of the carrier 2 relative to the base 1 by sensing the position of the tunnel magnetoresistive sensor 62 relative to the magnetic grating 61. This facilitates the auxiliary drive component 3 in driving the carrier 2 to move. By providing feedback on the position of the carrier 2, the movement accuracy of the carrier 2 is improved, thereby enhancing the optical zoom / focus quality of the camera module 100.

[0148] For example, the second shielding plate 8 can be used to wrap at least a portion of the magnetic grating 61 to block magnetic field interference between the magnetic grating 61 and the drive assembly 3, thereby reducing the risk of magnetic interference.

[0149] Please see Figure 5A and Figure 5B , Figure 5A yes Figure 3 The diagram shows the structure of the base 1 in some embodiments of the motor 20. Figure 5B yes Figure 5AThe diagram shows the structure of base 1 from another perspective.

[0150] In some embodiments, the base 1 may include a bottom 11, a first side 12, and a second side 13, the first side 12 and the second side 13 being connected to opposite sides of the bottom 11. The first side 12 and the second side 13 may be arranged in a third direction Y.

[0151] For example, the first side portion 12 may include a first support plate 121 and a second support plate 122 arranged in the first direction X. The first support plate 121 and the second support plate 122 may be arranged at intervals.

[0152] The first support plate 121 may have a first mounting portion 1211 protruding toward the second side 13, and the first mounting portion 1211 may be connected to the bottom 11.

[0153] The second support plate 122 may have a second mounting portion 1221 protruding toward the second side portion 13, and the second mounting portion 1221 may be connected to the bottom 11.

[0154] The second mounting portion 1221 and the first mounting portion 1211 can be arranged facing each other. "Facing each other" means that, along the first direction X, the orthographic projection of the first mounting portion 1211 onto the second support plate 122 at least partially overlaps with the second mounting portion 1221.

[0155] For example, the second side portion 13 may include a third support plate 131, a connecting plate 132, and a fourth support plate 133 arranged in the first direction X. The connecting plate 132 may be connected between the third support plate 131 and the fourth support plate 133.

[0156] The third support plate 131 may have a third mounting portion 1311 protruding toward the first side portion 12, and the third mounting portion 1311 may be connected to the bottom 11.

[0157] The fourth support plate 133 may have a fourth mounting portion 1331 protruding toward the first side portion 12, and the fourth mounting portion 1331 may be connected to the bottom 11.

[0158] The fourth mounting part 1331 may be disposed directly opposite to the third mounting part 1311. "Dealt directly opposite" means that, along the first direction X, the orthographic projection of the third mounting part 1311 onto the fourth support plate 133 at least partially coincides with the fourth mounting part 1331.

[0159] For example, the bottom 11 may expose the first side 12 in the third direction Y, that is, in the third direction Y, the length of the bottom 11 is greater than the maximum distance between the first side 12 and the second side 13, and a portion of the bottom 11 extends beyond the first side 12.

[0160] Please refer to the following: Figure 6 and Figure 7 , Figure 6 yes Figure 5A The diagram shows the structural schematic of the mounting portion of the base 1 in some embodiments; Figure 7 yes Figure 6 The diagram shown is a partial structural decomposition diagram in some embodiments.

[0161] In some embodiments, the first connector 4a and the second connector 4b may be arranged at intervals, the first connector 4a may be connected to the first side 12, and the second connector 4b may be connected to the second side 13.

[0162] For example, the first connector 4a can be connected between the first mounting portion 1211 and the second mounting portion 1221, and the second connector 4b can be connected between the third mounting portion 1311 and the fourth mounting portion 1331. In this embodiment, the design of the first mounting portion 1211 and the second mounting portion 1221 facilitates the installation of the first connector 4a, and the design of the third mounting portion 1311 and the fourth mounting portion 1331 facilitates the installation of the second connector 4b.

[0163] Among them, the first connecting member 4a can be a sliding shaft, and the second connecting member 4b can be a sliding shaft.

[0164] In some embodiments, the first circuit board 5 may be mounted on the bottom 11, and the tunnel magnetoresistive sensor 62 may be mounted on the first circuit board 5 so that the first circuit board 5 can power the tunnel magnetoresistive sensor 62.

[0165] For example, the first circuit board 5 may be partially mounted between the first support plate 121 and the second support plate 122, and a portion of the first circuit board 5 may extend out relative to the first side 12 along the third direction Y-direction away from the second side 13.

[0166] The edge of the first circuit board 5 facing away from the second side 13 can be flush with the edge of the bottom 11 facing away from the second side 13.

[0167] In some embodiments, the first coil 311 and the second coil 312 may be arranged in the first direction X, and both the first coil 311 and the second coil 312 may be mounted on the first side portion 12.

[0168] For example, the first coil 311 and the second coil 312 can both be installed between the first support plate 121 and the second support plate 122.

[0169] The first coil 311 and the second coil 312 can be electrically connected to the first circuit board 5 so that the first circuit board 5 can supply power to the first coil 311 and the second coil 312.

[0171] In some embodiments, the motor 20 may further include a second circuit board 15, on which the first coil 311 and the second coil 312 may be mounted. The second circuit board 15 may be fixed to the first side portion 12 to achieve fixed mounting of the first coil 311 and the second coil 312.

[0172] In other embodiments, the first coil 311 and the second coil 312 can be at least partially embedded in the first side portion 12 to achieve fixed installation of the first coil 311 and the second coil 312. Alternatively, the first coil 311 and the second coil 312 can be integrally formed with the first side portion 12 through injection molding to improve the installation stability of the first coil 311 and the second coil 312.

[0173] Please refer to the following: Figures 9A to 10 , Figure 9A yes Figure 3 The schematic diagram of the carrier 2 in some embodiments of the motor 20 shown is shown. Figure 9B yes Figure 9A A schematic diagram of the structure of carrier 2 from another perspective; Figure 10 yes Figure 9A The diagram shows a cross-section of carrier 2 along line BB in some embodiments.

[0174] In some embodiments, the carrier 2 may include a first carrier portion 21, a second carrier portion 22, a third carrier portion 23, and a fourth carrier portion 24 connected end-to-end. The first carrier portion 21 and the third carrier portion 23 may be arranged in a third direction Y, and the second carrier portion 22 and the fourth carrier portion 24 may be arranged in a second direction Z. The first carrier portion 21, the second carrier portion 22, the third carrier portion 23, and the fourth carrier portion 24 may be arranged to form a receiving space 25, which may be used to mount at least a portion of the lenses in the lens 40 described above.

[0175] For example, the surface of the first carrier 21 facing away from the second carrier 22 may be provided with a first receiving groove 211, and the opening of the first receiving groove 211 may face away from the second carrier 22.

[0176] For example, the surface of the first carrier 21 facing away from the fourth carrier 24 may be provided with a second receiving groove 212, and the opening of the second receiving groove 212 may face away from the fourth carrier 24.

[0177] In some embodiments, the carrier 2 is provided with a first groove 26 and a second groove 27 on the side near the second carrier portion 22.

[0178] In some examples, the second carrier 22 may be provided with a first groove 26. In other examples, the first carrier 21 may be provided with a first groove 26. In still other examples, the first carrier 21 and the second carrier 22 may be enclosed to form the first groove 26. The opening of the first groove 26 may face away from the fourth carrier 24.

[0179] In some examples, the second carrier 22 may be provided with a second groove 27. In other examples, the third carrier 23 may be provided with a second groove 27. In still other examples, the second carrier 22 and the third carrier 23 may be enclosed to form the second groove 27. The opening of the second groove 27 may face away from the fourth carrier 24.

[0180] The extension directions of the first groove 26 and the second groove 27 can be parallel to the first direction X.

[0181] In some examples, the first groove 26 can be a U-shaped groove or an L-shaped groove, and the second groove 27 can be a V-shaped groove.

[0182] In other examples, the first groove 26 can be a V-groove, and the second groove 27 can be a U-groove or an L-groove.

[0183] In some other examples, the first slide 26 and the second slide 27 may also have other shapes, and the shapes of the first slide 26 and the second slide 27 may be the same or different, which is not limited here.

[0184] In some embodiments, the carrier 2 may have a first reinforcing plate 28 and a second reinforcing plate 29. The first reinforcing plate 28 may be embedded within the second carrier portion 22 to improve the structural strength of the second carrier portion 22. The second reinforcing plate 29 may be embedded within the fourth carrier portion 24 to improve the structural strength of the fourth carrier portion 24.

[0185] In some embodiments, the two surfaces of the first carrier 21 opposite to each other along the first direction X may be provided with a first buffer 16a and a second buffer 16b, respectively. The two surfaces of the third carrier 23 opposite to each other along the first direction X may be provided with a third buffer 16c and a fourth buffer 16d, respectively.

[0186] Please refer to the following: Figures 11A to 13 , Figure 11A yes Figure 9A The diagram shows a partial structural schematic of the mounting portion of carrier 2 in some embodiments. Figure 11B yes Figure 11A A schematic diagram of the structure shown from another perspective; Figure 12 yes Figure 11A The diagram shown is a partial structural breakdown of the structure in some embodiments. Figure 13 yes Figure 11A The diagram shown is a cross-section along line CC in some embodiments.

[0187] In some embodiments, the first magnetic element 321 and the second magnetic element may both be mounted on one side of the carrier 2.

[0188] For example, the magnetic guide plate 9 can be installed in the first receiving groove 211, and the first magnetic element 321 and the second magnetic element 322 can both be installed in the first receiving groove 211 and partially covered by the magnetic guide plate 9. In this embodiment, by installing the first magnetic element 321 and the second magnetic element 322 in the first receiving groove 211, not only can the installation stability of the first magnetic element 321 and the second magnetic element 322 be improved, but it is also beneficial to reduce the space occupied by the first magnetic element 321 and the second magnetic element 322, thereby facilitating the miniaturization design of the motor 20.

[0189] The magnetic plate 9 can be C-shaped so that it can wrap around the first magnetic component 321 and the second magnetic component 322, thereby improving the installation stability of the first magnetic component 321 and the second magnetic component.

[0190] In some embodiments, the magnetic grating 61 may be mounted on the carrier 2. Specifically, the magnetic grating 61 may be mounted on the first carrier portion 21 and extended along the first direction X.

[0191] For example, the magnetic grating 61 can be installed in the second receiving groove 212, which can improve the stability of the installation of the magnetic grating 61 and reduce the space occupied by the magnetic grating 61, thereby facilitating the miniaturization design of the motor 20.

[0192] The second shielding plate 8 may include a first sub-plate 81 and a second sub-plate 82, with the first sub-plate 81 and the second sub-plate 82 connected in an L-shape. The second shielding plate 8 may be installed in the second receiving groove 212, and the magnetic grating 61 may be installed on the second shielding plate 8. The first sub-plate 81 may be located between the magnetic grating 61 and the first magnetic element 321 and the second magnetic element 322 to reduce magnetic field interference between the magnetic grating 61 and the first magnetic element 321 and the second magnetic element 322.

[0193] The second sub-plate 82 can be located on the side of the magnetic grating 61 facing away from the third carrier 23, so as to block the magnetic fields of the first magnetic element 321 and the second magnetic element 322, thereby reducing the magnetic field interference of the first magnetic element 321 and the second magnetic element 322 on the magnetic grating 61.

[0194] Please refer to the following: Figures 14 to 16 , Figure 14 yes Figure 11AThe structure shown is installed at Figure 6 The diagram shown is a structural schematic in some embodiments; Figure 15 yes Figure 14 The diagram shown is a partial structural breakdown of the structure in some embodiments. Figure 16 yes Figure 14 The diagram shown is a cross-section along line DD in some embodiments.

[0195] In some embodiments, the carrier 2 may be mounted on the base 1. At least a portion of the first carrier 21 may be located between the first support plate 121 and the second support plate 122, the second carrier 22 may be closer to the bottom 11 than the fourth carrier 24, and at least a portion of the third carrier 23 may be located between the third support plate 131 and the fourth support plate 133.

[0196] In this embodiment, by installing at least a portion of the first carrier 21 between the first support plate 121 and the second support plate 122, and installing at least a portion of the third carrier 23 between the third support plate 131 and the fourth support plate 133, the extra space occupied by the carrier 2 is reduced, thereby improving space utilization and facilitating the miniaturization design of the motor 20.

[0197] In some embodiments, the first connector 4a and the second connector 4b can both be used to connect the carrier 2 and the base 1. Specifically, the first connector 4a can be installed within the first sliding groove 26, and the second connector 4b can be installed within the second sliding groove 27. Both the first connector 4a and the second connector 4b can be sliding shafts.

[0198] In this embodiment, by setting the first connector 4a and the second connector 4b as sliding shafts and respectively set in the first sliding groove 26 and the second sliding groove 27, it is beneficial to improve the stability of the carrier 2 moving relative to the base 1 in the first direction X, thereby improving the quality of optical zoom / focusing of the camera module 100.

[0199] In this embodiment, since one of the first sliding groove 26 and the second sliding groove 27 can be a U-shaped groove or an L-shaped groove, and the other can be a V-shaped groove, the stability of the connection between the first sliding shaft and the second sliding shaft and the carrier 2 can be enhanced, thereby improving the stability of the carrier 2 installed on the base 1 and the stability of the carrier 2 moving relative to the base 1 in the first direction X, thereby improving the quality of optical zoom / focusing of the camera module 100.

[0200] In this embodiment, due to the installation of the tunnel magnetoresistive sensor 62 and the magnetic grating 61, during the movement of the carrier 2 relative to the base 1 along the first direction X, the tunnel magnetoresistive sensor 62 can detect the position of the tunnel magnetoresistive sensor 62 relative to the magnetic grating 61 by sensing the change in the magnetic field of the magnetic grating 61, thereby detecting the position of the carrier 2 relative to the base 1. This improves the position detection accuracy of the carrier 2 and is beneficial to improving the quality of optical zoom / focusing of the camera module 100. For example, through the cooperation of the tunnel magnetoresistive sensor 62 and the magnetic grating 61, the position detection accuracy can be improved to 3μm, 2μm, or 1μm, etc.

[0201] Furthermore, since the magnetic grating 61 is mounted on the first carrier 21, the tunnel magnetoresistive sensor 62 and the circuit board are both positioned close to the magnetic grating 61. This allows the tunnel magnetoresistive sensor 62, the magnetic grating 61, the driving magnet 32, and the driving coil 31 to be concentrated near the first side 12 of the carrier 2. As a result, the tunnel magnetoresistive sensor 62 and the magnetic grating 61 can be kept away from external magnetic interference sources on the side of the second side 13 of the motor 20 facing away from the first side 12, which helps to reduce the risk of magnetic interference to the tunnel magnetoresistive sensor 62 and the magnetic grating 61.

[0202] In other embodiments, the first connecting member 4a may also be a ball bearing, a spring, or a suspension wire, and the second connecting member 4b may also be a ball bearing, a spring, or a suspension wire. It should be noted that when the first connecting member 4a and the second connecting member 4b are springs or suspension wires, the carrier 2 does not need to be provided with the first sliding groove 26 and the second sliding groove 27. Moreover, the spring or suspension wire can not only guide the movement of the carrier 2, but also limit the movement stroke of the carrier 2 through the elasticity of the spring or suspension wire.

[0203] In some embodiments, the second sub-plate 82 of the second shielding plate 8 can be located between the magnetic grating 61 and the driving coil 31, so that the second sub-plate 82 can separate the magnetic grating 61 and the driving coil 31, reduce the magnetic field interference between the driving coil 31 and the magnetic grating 61 after the driving coil 31 is energized, and improve the stability of the position detection of the position detection component 6.

[0204] Please refer to the following: Figure 9A , Figure 9B and Figure 14In this embodiment, since the two surfaces of the first carrier 21 opposite to each other along the first direction X can be respectively provided with a first buffer 16a and a second buffer 16b, and the two surfaces of the third carrier 23 opposite to each other along the first direction X can be respectively provided with a third buffer 16c and a fourth buffer 16d, the first buffer 16a can play a collision buffering role between the first carrier 21 and the first support plate 121, the second buffer 16b can play a collision buffering role between the first carrier 21 and the second support plate 122, the third buffer 16c can play a collision buffering role between the third carrier 23 and the third support plate 131, and the fourth buffer 16d can play a collision buffering role between the third carrier 23 and the fourth support plate 133, thereby reducing the risk of collision damage between the carrier 2 and the base 1 and improving the service life of the motor 20.

[0205] In other embodiments, the first buffer 16a may also be disposed on the surface of the first support plate 121 facing the first carrier 21, the second buffer 16b may also be disposed on the surface of the second support plate 122 facing the first carrier 21, the third buffer 16c may also be disposed on the surface of the third support plate 131 facing the third carrier 23, and the fourth buffer 16d may also be disposed on the surface of the fourth support plate 133 facing the third carrier 23.

[0206] In some other embodiments, the number of the first buffer 16a, the second buffer 16b, the third buffer 16c, and the fourth buffer 16d can all be two. Specifically, one first buffer 16a is mounted on the surface of the first carrier 21 facing the first support plate 121, and the other first buffer 16a is disposed on the surface of the first support plate 121 facing the first carrier 21; one second buffer 16b is disposed on the surface of the first carrier 21 facing the second support plate 122, and the other second buffer 16b is disposed on the surface of the second support plate 122 facing the first carrier 21; one third buffer 16c is disposed on the surface of the third carrier 23 facing the third support plate 131, and the other third buffer 16c is disposed on the surface of the third support plate 131 facing the third carrier 23; one fourth buffer 16d is disposed on the surface of the second carrier 22 facing the fourth support plate 133, and the other fourth buffer 16d is disposed on the surface of the fourth support plate 133 facing the third carrier 23.

[0207] Please refer to the following: Figures 16 to 17B , Figure 17A yes Figure 14 The diagram shows the structure in which the driving magnet 32 ​​and the driving coil 31 are matched in some embodiments. Figure 17B yes Figure 17A The diagram shows the structure from another perspective.

[0208] In some embodiments, the first magnetic element 321 can be arranged opposite to the first coil 311, and the second magnetic element 322 can be arranged opposite to the second coil 312, which is conducive to the generation of Lorentz force, thereby facilitating the movement of the carrier 2 relative to the base 1.

[0209] For example, both the first magnetic element 321 and the second magnetic element 322 can be Heilbeck magnets. The first magnetic element 321 includes a first magnet 3211 and a second magnet 3212 arranged in the first direction X. Both the first magnet 3211 and the second magnet 3212 have magnetic pole faces facing the first coil 311. The polarity direction of the first magnet 3211 is opposite to that of the second magnet 3212. The second magnetic element 322 includes a third magnet 3221 and a fourth magnet 3222 arranged in the first direction X. The polarity direction of the third magnet 3221 is opposite to that of the first magnet 3211, and the polarity direction of the fourth magnet 3222 is opposite to that of the second magnet 3212.

[0210] It should be noted that polarity refers to the direction in which one magnetic pole faces of a magnet points to another magnetic pole face. Specifically, inside a magnet, the direction from the S pole to the N pole is the polarity of that magnet.

[0211] In this embodiment, since both the first magnetic element 321 and the second magnetic element 322 are Helbeck magnets, they can generate a stronger magnetic field for the same size. This increases the Lorentz force generated by the interaction between the driving magnet 32 ​​and the driving coil 31, thereby increasing the driving force of the driving coil 31 in moving the carrier 2 relative to the base 1. This helps to compensate for the insufficient power of the motor 20's unilateral drive. For example, the driving force can be increased to over 50 mN using Helbeck magnets.

[0212] Furthermore, by controlling the directions of the current flowing through the first coil 311 and the second coil 312 to be opposite, the force generated by the first coil 311 and acting on the first magnetic element 321 due to the magnetic effect of the current (see [link to documentation]). Figure 17B The force generated by F21 in the second coil 312 and acting on the second magnetic element 322 (see F21 in the second coil 312) (see F21 in the second coil 312) Figure 17BThe directions of F22 in the first coil 31 and the second coil 312 are opposite, thereby reducing or even eliminating the pushing or attracting force of the driving coil 31 on the driving magnet 32, thus reducing or even avoiding the risk of the driving coil 31 causing the carrier 2 to tip over. Due to the magnet arrangement characteristics in the Heilbeck magnet, when the current directions of the first coil 311 and the second coil 312 are opposite, the interaction between the first coil 311 and the first magnetic element 321 can generate a Lorentz force parallel to the first direction X. Since the first coil 311 is fixed to the base 1, the first magnetic element 321 will be subjected to a force in the opposite direction (see [reference]). Figure 17B In F11), the second coil 312 interacts with the second magnet 3212 to generate a Lorentz force parallel to the first direction X. Since the second coil 312 is fixed to the base 1, the second magnetic component 322 will be subjected to a force in the opposite direction (see F11). Figure 17B The forces in F11 and F12 are in the same direction.

[0213] For example, the first coil 311 includes a first long side 3111, a first short side 3112, a second long side 3113, and a second short side 3114 connected end to end. The first long side 3111 is directly opposite the first magnet 3211, and the second long side 3113 is directly opposite the second magnet 3212. The second coil 312 includes a third long side 3121, a third short side 3122, a fourth long side 3123, and a fourth short side 3124 connected end to end. The third long side 3121 is directly opposite the third magnet 3221, and the fourth long side 3123 is directly opposite the fourth magnet 3222.

[0214] In this embodiment, by aligning the first long side 3111 with the first magnet 3211 and the second long side 3113 with the second magnet 3212, the magnetic field interaction between the first coil 311 and the first magnetic component 321 after energization is enhanced, thereby increasing the magnitude of the Lorentz force and thus the driving force on the first magnetic component 321. Similarly, by aligning the third long side 3121 with the third magnet 3221 and the fourth long side 3123 with the fourth magnet 3222, the magnetic field interaction between the second coil 312 and the second magnetic component 322 after energization is enhanced, thereby increasing the magnitude of the Lorentz force and thus the driving force on the second magnetic component 322.

[0215] Specifically, with Figure 17A and Figure 17B For example, consider the marking of current and polarity. Figure 17A The dashed line with an arrow indicates the direction of the current. Figure 17BThe dashed line with an arrow indicates force. The magnetic pole face of the first magnet 3211 facing the first long side 3111 of the first coil 311 is the S pole. When used with the first coil 311, it can generate a Lorentz force opposite to the direction of F11. The magnetic pole face of the second magnet 3212 facing the second long side 3113 of the first coil 311 is the N pole. When used with the first coil 311, it can generate a Lorentz force opposite to the direction of F11. Thus, the interaction between the first coil 311 and the first magnetic element 321 can generate a force F11 that drives the first magnetic element 321. The magnetic pole face of the third magnet 3221 facing the third long side 3121 of the second coil 312 is the N pole. In conjunction with the second coil 312, it can generate a Lorentz force opposite to the direction of F12. The magnetic pole face of the fourth magnet 3222 facing the fourth long side 3123 of the second coil 312 is the S pole. In conjunction with the second coil 312, it can generate a Lorentz force opposite to the direction of F12. Thus, the interaction between the second coil 312 and the second magnetic element 322 can generate a force F12 that drives the second magnetic element 322. In this way, the drive coil 31 can drive the magnet 32 ​​to move the carrier 2 relative to the base 1 along the D0 direction (see [link to documentation]). Figure 16 )sports.

[0216] In some other embodiments, the first coil 311 and the second coil 312 can be directly printed on a flexible printed circuit board to achieve a smaller size design, which is beneficial to the miniaturization design of the motor 20.

[0217] It should be noted that, Figures 16 to 17B The diagram illustrates that the motor 20 may include a first coil 311 and a second coil 312. It is understood that in other embodiments, the motor 20 may also include more coils, such as a third coil, a fourth coil, etc., which are not limited here. In some embodiments, the number of coils and magnetic components may be the same. Multiple coils arranged along the first direction X sequentially change the current direction, and the corresponding magnetic components are designed with magnetic poles so that the direction of the Lorentz force generated after the interaction between each coil and its corresponding magnetic component is consistent. In other embodiments, the number of coils and magnetic elements may be different. One magnetic element may correspond to multiple coils with the same current direction. For example, the motor 20 may include a first coil 311, a second coil 312, and a third coil. The size of the second coil 312 and the third coil is smaller than that of the first coil 311. The current direction of the second coil 312 and the third coil is the same, while the current direction of the second coil 312 is opposite to that of the first coil 311. The second coil 312 and the third coil are arranged in the second direction Z, and the second coil 312 and the first coil 311 are arranged in the first direction X. The first coil 311 is directly opposite to the first magnetic element 321, and the second coil 312 and the third coil are directly opposite to the second magnetic element 322.

[0218] It should be noted that in the embodiments of this application, the number of the first magnetic element 321 and the second magnetic element 322 is not limited. It can be understood that in some other embodiments, the number of magnets in the first magnetic element 321 and the second magnetic element 322 can be other, as long as the magnetic element and the coil can cooperate to drive the carrier 2, and the magnetic force influence on the magnetic element caused by the magnetic effect of the current in the coil can be weakened or even eliminated.

[0219] For example, the first magnetic element 321 includes a first magnet 3211, a fifth magnet 3213, and a second magnet 3212 arranged in the first direction X. The polarity direction of the fifth magnet 3213 is different from that of the first magnet 3211 and the second magnet 3212. The second magnetic element 322 includes a third magnet 3221, a sixth magnet 3223, and a fourth magnet 3222 arranged in the first direction X. The polarity direction of the sixth magnet 3223 is different from that of the third magnet 3221 and the fourth magnet 3222.

[0220] In this embodiment, in the first magnetic component 321, the fifth magnet 3213 is designed to guide the magnetic fields of the first magnet 3211 and the second magnet 3212, which helps to enhance the magnetic field exerted by the first magnetic component 321 on the first coil 311. In the second magnetic component 322, the sixth magnet 3223 is designed to guide the magnetic fields of the third magnet 3221 and the fourth magnet 3222, which helps to enhance the magnetic field exerted by the second magnetic component 322 on the second coil 312.

[0221] In some embodiments, the first magnetic element 321 and the second magnetic element 322 can be a separate structure, so that the combination of the first magnetic element 321 and the second magnetic element 322 is more flexible.

[0222] In other embodiments, the first magnetic component 321 and the second magnetic component 322 can be an integral structure, which facilitates the installation of the first magnetic component 321 and the second magnetic component 322. The first magnetic component 321 and the second magnetic component 322 can be manufactured into an integral structure by means of bonding, welding, etc.

[0223] In some embodiments, the second magnet 3212 and the third magnet 3221 can be a separate structure, which is beneficial for the flexible arrangement of the second magnet 3212 and the third magnet 3221.

[0224] In other embodiments, the second magnet 3212 and the third magnet 3221 can be an integral structure.

[0225] In this embodiment, since the polarity direction of the second magnet 3212 is the same as that of the third magnet 3221, designing the second magnet 3212 and the third magnet 3221 as an integral structure helps to avoid the mutual repulsion between the second magnet 3212 and the third magnet 3221, thereby facilitating installation.

[0226] The second magnet 3212 and the third magnet 3221 can be made into an integral structure by means of bonding, welding or other methods, or the second magnet 3212 and the third magnet 3221 can be a whole magnet, of which part is the second magnet 3212 and the other part is the third magnet 3221.

[0227] It should be noted that in this embodiment, the camera module 100 is illustrated with the driving magnet 32 ​​and driving coil 31 mounted on the side of the carrier 2 near the first side 12. In other embodiments, the number of driving magnets 32 and driving coils 31 can both be two, with one driving magnet 32 ​​and driving coil 31 mounted on the side of the carrier 2 near the first side 12 and the other driving magnet 32 ​​and driving coil 31 mounted on the side of the carrier 2 near the second side 13. In this embodiment, the dual-sided mounting design of the driving magnets 32 and driving coils 31 ensures that the force exerted by the driving coils 31 on the driving magnets 32 due to the magnetic effect of the current on both sides of the carrier 2 is balanced, improving the balance of both sides of the carrier 2 and thus improving the overall balance of the carrier 2. This is beneficial for improving the optical zoom / focus quality of the camera module 100.

[0228] Understandably, in order to reduce or even eliminate the impact of external magnetic interference on the operation of the driving magnet 32 ​​and the driving coil 31 of the camera module 100, a single-sided driving motor 20 design can be adopted, that is, the driving magnet 32 ​​and the driving coil 31 are only installed on one side of the carrier 2, for example, the side of the carrier 2 near the first side 12 in this embodiment. If the impact of external magnetic interference is small, a dual-sided driving motor 20 design can be adopted, that is, a driving magnet 32 ​​and a driving coil 31 are provided on both opposite sides of the carrier 2, for example, in Figure 2B In the scenario shown, the side camera module 600 can adopt the above-mentioned design of driving magnet 32 ​​and driving coil 31, and be installed on both sides to improve driving balance.

[0229] Please see Figure 18 , Figure 18 yes Figure 14 The diagram shows a schematic representation of the mating structure between the driving magnet 32 ​​and the driving coil 31 in some other embodiments. It should be noted that... Figure 18 The driving component 3 shown may include Figure 17A and Figure 17B Some features of the driving component 3 shown are described below; the same features will not be repeated here.

[0230] In some embodiments, the first magnet 3211 may have a first magnetization direction and a first polarization direction, which are arranged at a non-90° angle. The second magnet 3212 may have a second magnetization direction and a second polarization direction, which are arranged at a non-90° angle. The components of the first magnetization direction in the first direction X and the components of the second magnetization direction in the first direction X point in the same direction.

[0231] It should be noted that the magnetization direction of a magnet is the direction of the internal magnetic field lines of the magnet. By using an oblique magnetization method, the magnetization direction of the magnet can be made not perpendicular to the magnetic pole surface. In the accompanying drawings of the embodiments of this application, the magnetization direction of the magnet is indicated by a dashed line with an arrow.

[0232] In this embodiment, since the first magnetization direction of the first magnet 3211 is deviated from the center of the first magnetic element 321, the magnetic field lines of the N pole surface of the first magnet 3211 pointing towards the S pole surface of the second magnet 3212 are squeezed toward the center of the first magnetic element 321, thereby increasing the magnetic flux density on one side of the first magnetic element 321, and further increasing the magnetic flux density perpendicular to the first coil 311. When the first coil 311 is energized, a larger Lorentz force can be generated in the first coil 311 through the action of the first magnetic element 321, which is beneficial to provide a stronger driving force.

[0233] In some embodiments, the third magnet 3221 may have a third magnetization direction and a third polarity direction, which are not at a 90° angle. The fourth magnet 3222 may have a fourth magnetization direction and a fourth polarity direction, which are not at a 90° angle. The components of the third magnetization direction in the first direction and the components of the fourth magnetization direction in the first direction have the same orientation.

[0234] In this embodiment, since the third magnetization direction of the fourth magnet 3222 is deviated from the center of the second magnetic element 322, the magnetic field lines of the N pole surface of the fourth magnet 3222 pointing towards the S pole surface of the third magnet 3221 are squeezed toward the center of the second magnetic element 322, thereby increasing the magnetic flux density on one side of the second magnetic element 322, and further increasing the magnetic flux density perpendicular to the second coil 312. When the second coil 312 is energized, a larger Lorentz force can be generated in the second coil 312 through the action of the second magnetic element 322, which is beneficial to provide a stronger driving force.

[0235] It should be noted that, in some embodiments, Figure 18The first magnetic element 321 and the second magnetic element 322 shown may include only two magnets. In some other embodiments, the first magnetic element 321 and the second magnetic element 322 may also include a greater number of magnets. See details. Figure 19A and Figure 19B .

[0236] Please refer to the following: Figure 19A and Figure 19B , Figure 19A yes Figure 14 The diagram shows the structure in which the driving magnet 32 ​​and the driving coil 31 are matched in some other embodiments. Figure 19B yes Figure 14 The diagram shows a schematic representation of the mating structure between the driving magnet 32 ​​and the driving coil 31 in some embodiments. It should be noted that... Figure 19A and Figure 19B The driving component 3 shown may include Figure 18 Some features of the driving component 3 shown are described below; the same features will not be repeated here.

[0237] In some embodiments, the first magnetic element 321 may further include a fifth magnet 3213 and a seventh magnet 3214, both of which are located between the first magnet 3211 and the second magnet 3212. The fifth magnet 3213 is closer to the first magnet 3211 than the seventh magnet 3214. The polarity direction of the fifth magnet 3213 is the same as that of the first magnet 3211, and the polarity direction of the seventh magnet 3214 is the same as that of the second magnet 3212.

[0238] In this embodiment, by increasing the number of magnets, the magnetic field strength of the first magnetic element 321 can be enhanced, thereby increasing the Lorentz force generated by the combined action of the first magnetic element 321 and the first coil 311, and thus increasing the driving force of the driving component 3.

[0239] For example, the fifth magnet 3213 may have a fifth magnetization direction and a fifth polarization direction, wherein the fifth magnetization direction and the fifth polarization direction are set at an angle other than 90°, and / or, the seventh magnet 3214 may have a seventh magnetization direction and a seventh polarization direction, wherein the seventh magnetization direction and the seventh polarization direction are set at an angle other than 90°.

[0240] In this embodiment, the N-pole surface of the fifth magnet 3213 is oriented in the same direction as the N-pole surface of the first magnet 3211. This allows the fifth magnet 3213 to work with the first magnet 3211 to provide a magnetic field perpendicular to the first coil 311. Furthermore, the fifth magnet 3213 enhances the compression effect of the magnetic field lines of the first magnet 3211, thereby further increasing the magnetic flux density of the first magnetic element 321 on the side of the first coil 311, and consequently increasing the Lorentz force generated by the combined action of the first magnetic element 321 and the first coil 311. Similarly, the seventh magnet 3214 and the second magnet 3212 also enhance the Lorentz force generated by the combined action of the first magnetic element 321 and the first coil 311.

[0241] It should be noted that, in the embodiments of this application, in the first magnetic element 321, the component of the first magnetization direction in the first direction may be opposite to the component of the fifth magnetization direction in the first direction, and the component of the second magnetization direction in the first direction may be opposite to the component of the seventh magnetization direction in the first direction. In some other embodiments, the component of the first magnetization direction in the first direction may be the same as the component of the fifth magnetization direction in the first direction, and the component of the second magnetization direction in the first direction may be the same as the component of the seventh magnetization direction in the first direction.

[0242] In some embodiments, the second magnetic element 322 may further include a sixth magnet 3223 and an eighth magnet 3224, both of which are located between the third magnet 3221 and the fourth magnet 3222. The sixth magnet 3223 is closer to the third magnet 3221 than the eighth magnet 3224. The polarity direction of the sixth magnet 3223 is the same as that of the third magnet 3221, and the polarity direction of the eighth magnet 3224 is the same as that of the fourth magnet 3222.

[0243] In this embodiment, by increasing the number of magnets, the magnetic field strength of the second magnetic element 322 can be enhanced, thereby increasing the Lorentz force generated by the combined action of the second magnetic element 322 and the second coil 312, and thus increasing the driving force of the drive assembly 3.

[0244] For example, the sixth magnet 3223 has a sixth magnetization direction and a sixth polarization direction, which are set at a non-90° angle to each other, and / or the eighth magnet 3224 has an eighth magnetization direction and an eighth polarization direction, which are set at a non-90° angle to each other.

[0245] In this embodiment, the orientation of the S-pole surface of the sixth magnet 3223 is the same as that of the S-pole surface of the third magnet 3221. This allows the sixth magnet 3223 and the third magnet 3221 to jointly provide a magnetic field perpendicular to the first coil 311. Furthermore, the sixth magnet 3223 enhances the compression effect of the magnetic field lines of the third magnet 3221, thereby further increasing the magnetic flux density of the second magnetic element 322 on the side of the second coil 312, and consequently increasing the Lorentz force generated by the combined action of the second magnetic element 322 and the second coil 312. Similarly, the eighth magnet 3224 and the fourth magnet 3222 also enhance the Lorentz force generated by the combined action of the second magnetic element 322 and the second coil 312.

[0246] It should be noted that, in the embodiments of this application, in the second magnetic element 322, the component of the third magnetization direction in the first direction may be opposite to the component of the sixth magnetization direction in the first direction, and the component of the fourth magnetization direction in the first direction may be opposite to the component of the eighth magnetization direction in the first direction. In some other embodiments, the component of the third magnetization direction in the first direction may be the same as the component of the sixth magnetization direction in the first direction, and the component of the fourth magnetization direction in the first direction may be the same as the component of the eighth magnetization direction in the first direction.

[0247] It should be noted that in the first magnetic component 321 and the second magnetic component 322, the angles between the magnetic field lines of the magnet and the polarity direction can be the same (see [reference]). Figure 19A They can also be different (see...). Figure 19B (This is not restricted.)

[0248] Please refer to the following: Figure 20 and Figure 21 , Figure 20 yes Figure 14 The diagram shown is a cross-section of the structure along line DD in some other embodiments; Figure 21 yes Figure 14 The diagram shown is a cross-section along line DD in some other embodiments.

[0249] In some embodiments, the motor 20 may also include a balancing assembly 17, which may connect the third carrier 23 and the bottom 11, and may be used to generate opposing forces acting between the third carrier 23 and the bottom 11.

[0250] In this embodiment, since the first carrier portion 21 of the carrier 2 is equipped with a first magnetic element 321 and a second magnetic element 322, while the third carrier portion 23 of the carrier 2 is not equipped with a magnetic element, the load on the carrier 2 in the first carrier portion 21 is greater than the load on the third carrier portion 23. This may cause balance interference to the movement of the carrier 2. By designing the balancing component 17, it can act between the third carrier portion 23 and the bottom 11 to generate opposing forces between the third carrier portion 23 and the bottom 11, thereby pulling the third carrier portion 23 toward the bottom 11, which is equivalent to increasing the load on the third carrier portion 23, thereby balancing the loads of the first carrier portion 21 and the third carrier portion 23. At this time, the pressure between the first carrier portion 21 and the first connecting member 4a and the pressure between the third carrier portion 23 and the second connecting member 4b can be close or even completely the same, thereby balancing the frictional force on the first carrier portion 21 side and the frictional force on the third carrier portion 23 side when the carrier 2 moves, which is beneficial to improving the movement balance of the carrier 2.

[0251] For example, the balancing component 17 can generate a force acting on the third load 23 pointing towards the bottom 11, or the balancing component 17 can be used to generate a force acting on the bottom 11 pointing towards the third load 23, or the balancing component 17 can both generate a force acting on the third load 23 pointing towards the bottom 11 and generate a force acting on the bottom 11 pointing towards the third load 23.

[0252] In some examples (see) Figure 20 The balancing component 17 may include an elastic element 171. The elastic element 171 may connect the third carrier 23 and the bottom 11, and the elastic element 171 is in a stretched state.

[0253] In this embodiment, since the elastic element 171 is in a stretched state, it can act on the third carrier 23 and the bottom 11 through its elastic recovery force, generating opposing forces between the third carrier 23 and the bottom 11 to pull the third carrier 23 toward the bottom 11, thereby balancing the load of the first carrier 21 and the third carrier 23. Furthermore, since the elastic element 171 can deform in various directions, it can be pulled in the first direction X when the carrier 2 moves relative to the base 1, without interfering with the movement of the carrier 2. Moreover, the elastic element 171 can also limit the movement of the carrier 2 relative to the base 1 through its elasticity, confining the carrier 2 within its range of motion, which is beneficial for collision prevention.

[0254] It should be noted that, Figure 20 The elastic element 171 is only shown schematically, and its shape and number are not limited. It is understood that the elastic element 171 can also be other shapes, such as Z-shaped, C-shaped, etc., and the elastic element 171 can also be other numbers, such as 2, 3, or more.

[0255] In other examples (see Figure 21 The balancing assembly 17 may include a balancing magnet 172 and a magnetic body 173, with the balancing magnet 172 and the magnetic body 173 at least partially facing each other. The balancing magnet 172 magnetically attracts the magnetic body 173. Alternatively, the balancing magnet 172 is mounted on the third carrier 23, and the magnetic body 173 is mounted on the bottom 11; or, the balancing magnet 172 is mounted on the bottom 11, and the magnetic body 173 is mounted on the third carrier 23.

[0256] In this embodiment, by setting a balancing magnet 172 and a magnetic body 173, the magnetic attraction between them can be used to pull the third carrier 23 toward the bottom 11, thereby balancing the load of the first carrier 21 and the third carrier 23. Since the balancing magnet 172 and the magnetic body 173 can still generate magnetic attraction even when spaced apart, the design of the balancing magnet 172 and the magnetic body 173 will not cause frictional interference to the movement of the carrier 2 relative to the base 1.

[0257] Please refer to the following: Figure 4 , Figure 22A and Figure 22B , Figure 22A yes Figure 3 The diagram shows a schematic of the structure of the motor 20 in some embodiments, in which the housing 10 is fitted with the first shielding plate 7. Figure 22B yes Figure 22A The diagram shown is a cross-section along line EE in some embodiments.

[0258] In some embodiments, the housing 10 may include a first side panel 101, a second side panel 102, a front panel 103, a rear panel 104, and a top panel 105. The first side panel 101 and the second side panel 102 are spaced apart in a third direction Y. The front panel 103 is connected between the first side panel 101 and the second side panel 102. The rear panel 104 is also connected between the first side panel 101 and the second side panel 102, and the front panel 103 and the rear panel 104 are spaced apart in a first direction X. The first side panel 101, the second side panel 102, the front panel 103, and the rear panel 104 may enclose a space having two opposing openings in the second direction Z. The top panel 105 covers one of the openings and is simultaneously connected to one side of the first side panel 101, the second side panel 102, the front panel 103, and the rear panel 104.

[0259] The front plate 103 may have a first through hole 1031, and the rear plate 104 may have a second through hole 1041. The first through hole 1031 and the second through hole 1041 may be arranged opposite each other along the first direction X, so that when the motor 20 is mounted with at least part of the lens 40, light can pass through the first through hole 1031 and the second through hole 1041 in sequence.

[0260] The side of the first side plate 101 facing away from the top plate 105 may have a slot 1011.

[0261] In some embodiments, the first shielding plate 7 may be installed on the inner wall of the housing 10. Specifically, the first shielding plate 7 may be installed on the surface of the first side plate 101 facing the second side plate 102.

[0262] The first shielding plate 7 can be fixedly installed on the inner wall of the outer shell 10 by means of bonding, welding or other methods.

[0263] Please refer to the following: Figure 3 , Figure 23 and Figure 24 , Figure 23 yes Figure 3 A partial structural schematic diagram of the motor 20 shown in one embodiment, cut along line FF. Figure 24 yes Figure 3 The diagram shown is a structural schematic of the motor 20 without the first shielding plate 7 in some embodiments.

[0264] In some embodiments, the first shielding plate 7 may be located between the first side portion 12 and the inner wall of the outer casing 10, and the first shielding plate 7 may be arranged directly opposite the first coil 311 and the second coil 312.

[0265] In this embodiment, by designing the first shielding plate 7, the first coil 311 and the second coil 312 can be shielded to reduce the noise of the first coil 311 and the second coil 312 after being energized passing through the outer casing 10, which can reduce the background noise and thus reduce the noise generated by the motor 20 during operation.

[0266] For example, the orthographic projections of the first coil 311 and the second coil 312 on the first shielding plate 7 can fall within the shielding plate, so that the first shielding plate 7 can better shield and cover the first coil 311 and the second coil 312, which is beneficial to improving the effect of shielding the noise generated by the operation of the first coil 311 and the second coil 312.

[0267] The first shielding plate 7 covers the gap between the first support plate 121 and the second support plate 122 in the first direction X, so that the first shielding plate 7, the first support plate 121, the second support plate 122, the first carrier 21 and the bottom 11 can enclose and form a space to accommodate the first coil 311 and the second coil 312. The spatial design can form a wrapping effect on the first coil 311 and the second coil 312, which is beneficial to improving the shielding effect on the noise generated by the operation of the first coil 311 and the second coil 312.

[0268] The thickness of the first shielding plate 7 can be greater than or equal to 0.25 mm (see [link]). Figure 24(L1 in the text). For example, the thickness of the first shielding plate 7 can be, but is not limited to, 0.25 mm, or 0.27 mm, or 0.29 mm, or 0.30 mm, or 0.32 mm, or 0.34 mm, or 0.35 mm, or 0.36 mm, or other values ​​greater than 0.25 mm.

[0269] In this embodiment, since the motor 20 adopts a single-sided drive method, the driving force required on one side is higher, which causes the first coil 311 and the second coil 312 to generate greater noise when they are working. By designing the thickness of the first shielding plate 7 to meet the above dimensions, the noise generated by the first coil 311 and the second coil 312 can be effectively shielded.

[0270] The design of the first shielding plate 7 can reduce the noise generated by the motor 20 to less than or equal to 23 decibels, thereby improving the quietness of the motor 20 and enhancing the user experience of the camera module 100 and electronic device 1000.

[0271] In some other embodiments, when the first coil 311 and the second coil 312 employ Figure 8B As shown, when the first coil 311 and the second coil 312 are at least embedded in the first side portion 12, the first side portion 12 can reinforce the installation of the first coil 311 and the second coil 312, and can cover at least a portion of the first coil 311 and the second coil 312. This results in less vibration generated by the operation of the first coil 311 and the second coil 312, which helps to reduce the noise generated by the operation of the first coil 311 and the second coil 312. Therefore, the first shielding plate 7 does not need to be designed to be very thick to achieve the expected noise shielding effect. For example, the thickness of the first shielding plate 7 can be less than 0.25 mm, and the noise generated by the motor 20 during operation can be less than or equal to 23 decibels.

[0272] In some embodiments, the edge of the first circuit board 5 facing away from the second side 13 can extend through a slot 1011 in the first side plate 101 of the housing 10.

[0273] In this embodiment, since the first side plate 101 of the outer casing 10 is provided with a slot 1011, the first circuit board 5 can be ejected from the outer casing 10 through the slot 1011. Correspondingly, pins can be provided on the part of the first circuit board 5 that is exposed outside the outer casing 10, so that the first circuit can be connected to other circuits, such as power supply circuits, control circuits, etc. The partial exposure of the first circuit board 5 is beneficial to shorten the wiring distance.

[0274] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0275] It should be noted that all the above figures are exemplary illustrations of this application and do not represent the actual size of the product. Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application.

[0276] The above are merely some embodiments and implementation methods of this application. The scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
