Technical Field

[0002] The present application relates to the technical field of photographing equipment, and in particular to a motor, a camera module and an electronic device. Background Art

[0003] In recent years, with the development of optical imaging technology, people have higher and higher requirements for the camera functions of portable electronic devices, requiring the camera modules configured in electronic devices to be able to achieve shooting at different focal lengths, such as telephoto shooting and macro shooting.

[0004] Typically, a camera module uses a motor to drive the movement of optical elements to achieve switching between shooting modes with different focal lengths. However, currently, since the motor has no self-locking capability or has poor self-locking capability, its reliability is poor and there is a risk of collision in shooting modes with different focal lengths. Summary of the Invention

[0005] The present application provides a motor, a camera module, and an electronic device. The motor includes a fixed base, a moving platform, a drive assembly, and a self-locking assembly. The self-locking assembly is mounted on the moving platform and can stably lock the moving platform and the fixed base by inserting a pin into a pin hole in the fixed base.

[0006] In the first aspect, the present application provides a motor. The motor includes a fixed base, a moving platform, a driving assembly and a self-locking assembly. The moving platform is connected to the fixed base, the moving platform is used to carry the optical element, and drive the optical element to move relative to the fixed base, the fixed base is provided with a plurality of pin holes, and the plurality of pin holes are arranged at intervals along the moving direction of the moving platform, wherein the motor has a light entrance hole, and the axial direction of the light entrance hole intersects with the moving direction of the moving platform. The driving assembly connects the moving platform and the fixed base, and is used to drive the moving platform to move relative to the fixed base. The self-locking assembly is installed on the moving platform, and the self-locking assembly includes a magnetic drive component, a pin shaft and a protruding magnetic attraction component. Among them, the magnetic drive component is used to drive the pin shaft to extend relative to the moving platform and insert into the pin hole to lock the moving platform and the fixed base, and the protruding magnetic attraction component is used to lock the pin shaft in the pin hole.

[0007] In the present application, the extended magnetic attraction part can attract the magnet after the pin shaft is extended, so that the pin shaft can maintain a stable state of being inserted into the pin hole, thereby improving the stability of the locking motion carrier and the fixed base. In addition, after the power is cut off for the coil in the magnetic drive part, although the coil no longer generates magnetic thrust on the magnet to push the pin shaft, the extended magnetic attraction part can attract the magnet, so that the pin shaft can still remain inserted into the pin hole, which is beneficial to saving energy. In addition, when the magnetic drive part drives the pin shaft to extend close to the extended limit position of the pin shaft, the extended magnetic attraction part can complete the locking of the pin shaft by magnetically attracting the magnet, thereby realizing auxiliary locking of the pin shaft at the extended limit position.

[0008] In some possible implementations, the magnetic drive component is further used to drive the pin shaft to retract relative to the moving platform to disengage from the pin hole, thereby unlocking the moving platform and the fixed base.

[0009] In this implementation, the pin can be driven to extend and retract by the magnetic drive component, so that the locking and unlocking of the moving platform and the fixed base are quick.

[0010] In some possible implementations, the moving platform has a bearing surface, the bearing surface faces away from the bottom wall of the fixed base, and the bearing surface is inclined relative to the bottom wall of the fixed base, and the bearing surface is used to bear the optical element.

[0011] In this implementation, since the optical element needs to change the direction of light incident through the through-hole in order to reflect the incident light to the image sensor, the optical element needs to be provided with a reflective surface that is inclined relative to the bottom wall of the fixed base. The moving stage is configured to conform to the optical element, and the optical element is mounted on a tilted supporting surface. The supporting surface is arranged corresponding to the reflective surface of the optical element, thereby improving the installation stability of the optical element. In addition, the optical element is mounted on the tilted supporting surface so that it is placed in the gap between the optical element and the fixed base, thereby improving the space utilization of the motor.

[0012] The moving platform has a receiving space, which is located between the bearing surface and the bottom wall of the fixed base and is used to receive the self-locking component.

[0013] In this implementation, by utilizing the portion of the moving platform between the supporting surface and the fixed base to provide a storage space, the space utilization of the moving platform is improved. The self-locking assembly is housed in the moving platform's storage space, which reduces the size of the motor and facilitates a slimmer and lighter motor design. Furthermore, since the self-locking assembly moves with the moving platform, installing it within the internal space of the moving platform also improves the stability of the combined movement of the self-locking assembly and the moving platform.

[0014] The moving platform may have reinforcing ribs, which are located in the inner space of the moving platform to separate the inner space of the moving platform into two receiving spaces to respectively receive the two self-locking components.

[0015] In this implementation, the provision of reinforcing ribs not only enhances the structural strength of the moving platform, but also separates the two self-locking components to reduce interference between the two self-locking components.

[0016] In some possible implementations, the driving assembly and the pin hole are located on different sides of the motion platform.

[0017] In this implementation, by locating the pin hole and the drive assembly on different sides of the motion platform, the extension of the pin in the self-locking assembly can be prevented from interfering with the installation space of the drive assembly. Furthermore, this can prevent the motion platform from being oversized on one side due to the installation of too many components, thereby improving space utilization.

[0018] In some possible implementations, the drive assembly includes a drive coil and a drive magnet, one of which is connected to a fixed base and the other is connected to a moving platform. The magnetic pole surface of the drive magnet is arranged non-perpendicular to the direction of movement of the pin shaft.

[0019] In this implementation, by setting the magnetic pole surface of the driving magnet, the direction of the magnetic field of the driving magnet can be made to intersect with the movement direction of the pin shaft, so that the direction of magnetic interference of the driving magnet on the magnet in the magnetic drive component intersects with the direction of movement of the pin shaft driven by the magnet, which can reduce the magnetic interference of the magnetic field of the driving magnet on the magnetic drive component, thereby reducing the impact on the extension and retraction of the pin shaft, so as to reduce the interference with the locking effect of the moving platform and the fixed base.

[0020] Among them, the magnetic pole surface of the driving magnet can be set parallel to the movement direction of the pin shaft to further reduce the component size of the magnetic field of the driving magnet in the movement direction of the pin shaft, thereby further reducing the magnetic interference of the magnetic field of the driving magnet on the magnetic drive component, and further reducing the impact on the extension and retraction of the pin shaft, so as to further reduce the interference with the locking effect of the moving platform and the fixed base.

[0021] In some possible implementations, the motor further includes a detection component, which is extended along the movement direction of the moving platform relative to the fixed base, and the detection component is used to detect the position of the fixed base on the moving platform.

[0022] In this implementation, the detection component is extended along the movement direction of the moving platform relative to the fixed base, so that the detection component can detect the position of the moving platform along the entire movement path of the moving platform, which is beneficial to improving the position detection accuracy of the moving platform, thereby improving the accuracy of the pin shaft aligning with the pin hole.

[0023] In some possible implementations, the detection component includes a tunnel magnetoresistance and a magnetic grating, the tunnel magnetoresistance is installed on the moving platform, the magnetic grating is installed on the fixed base, the magnetic grating extends along the movement direction of the moving platform relative to the fixed base, and the tunnel magnetoresistance and the magnetic grating are arranged opposite to each other.

[0024] In this implementation, the tunnel magnetoresistance can move with the moving platform. Within the entire range of the tunnel magnetoresistance movement, there is a part of the magnetic grid that is arranged opposite to the tunnel magnetoresistance, so that the position of the tunnel magnetoresistance can be obtained through the part where the magnetic grid and the tunnel magnetoresistance are opposite, and then the position of the moving platform relative to the fixed base can be determined to achieve position detection and alignment of the pin shaft and the pin hole.

[0025] Wherein, along the moving direction of the moving platform relative to the fixed base, the self-locking component and the magnetic grid are arranged at intervals.

[0026] In this implementation, along the direction of movement of the moving platform relative to the fixed base, the self-locking component is spaced apart from the magnetic grid, which can reduce the magnetic interference of the magnetic grid on the magnetic drive component, thereby reducing the impact on the extension and retraction of the pin shaft, so as to reduce the interference with the locking effect of the moving platform and the fixed base.

[0027] Among them, along the stacking direction of the driving component and the moving platform, the self-locking component can be arranged at intervals from the magnetic grid.

[0028] In this implementation, by spacing the self-locking component and the magnetic grid in multiple directions, the magnetic interference of the magnetic grid on the magnetic drive component can be reduced or even avoided, thereby reducing the impact on the extension and retraction of the pin shaft, thereby reducing the interference with the locking effect of the moving platform and the fixed base.

[0029] In some possible implementations, the self-locking assembly is configured to receive a control command and drive the pin to retract and disengage from the pin hole. The driving assembly is configured to drive the movable platform to move relative to the fixed base after the pin has disengaged from the pin hole. The detection assembly is configured to detect position information of the fixed base during the movement of the movable platform relative to the fixed base, and the position information of the fixed base is used to assist in aligning the pin with the pin hole. After the pin is aligned with the pin hole, the self-locking assembly is configured to drive the pin to extend and insert into the pin hole. The driving assembly is configured to stop driving the movable platform after the pin is inserted into the pin hole.

[0030] In this implementation, through the cooperation of the self-locking component, the driving component and the detection component, the orderly unlocking and locking of the moving platform and the fixed base can be achieved, so as to realize the orderly switching of the lens of the camera module in the electronic device.

[0031] In some possible implementations, along the moving direction of the moving stage relative to the fixed base, a distance between two pin holes at two ends of the plurality of pin holes is greater than or equal to 9000 μm.

[0032] In this implementation, the motor can drive the optical elements to achieve long-distance movement through the motion stage, providing sufficient layout space for lenses with different focal lengths, reducing or even avoiding structural layout interference between lenses with different focal lengths, and facilitating the switching of lenses with different focal lengths.

[0033] In some possible implementations, the load capacity of the motion platform is greater than or equal to 2000 mg.

[0034] In this implementation, the load capacity of the moving platform refers to the weight that it can carry for the optical element, that is, the moving platform provided in this application can drive an optical element with a weight greater than or equal to 2000 mg to move relative to a fixed base, thereby realizing super-heavy load movement.

[0035] In some possible implementations, the magnetic drive component includes a coil and a magnet, with the extended magnetic attraction component located on the side of the magnet facing the pin hole. The coil is fixed to the motion platform, and the magnet is fixedly connected to the pin. The coil is configured to pass a first current through the coil to push the magnet to extend the pin, and to pass a second current through the coil to pull the magnet to retract the pin. The second current has a direction opposite to that of the first current.

[0036] In this implementation, the drive pin can be extended and retracted by energizing and reversing the coil, allowing for quick locking and unlocking of the moving platform and fixed base. Furthermore, by setting the coil to be fixed and the magnet to move relative to the coil—a fixed-coil, moving-magnet design—this facilitates the coil's circuit connection, preventing coil movement from pulling on the coil's wiring harness, and improving the stability of the coil-driven magnet.

[0037] In some possible implementations, the magnetic drive component includes a coil and a magnet, and the extended magnetic component is located on the side of the magnet facing the pin hole. The coil is fixed to the moving carrier, and the magnet is fixedly connected to the pin shaft. The coil is annular, and the magnet and the coil are arranged coaxially. When the pin shaft is in a retracted state, the end portion of the magnet away from the extended magnetic component is located inside the coil, and the end portion of the magnet close to the extended magnetic component is exposed from the coil. And / or, when the pin shaft is in an extended state, the end portion of the magnet away from the extended magnetic component is located inside the coil.

[0038] In this implementation, the magnetic drive element adopts a cannon-barrel structure, enabling a dynamic magnetic ejection drive design with an outer coil and an inner magnet. By partially exposing the magnet to the coil when the pin is extended or retracted, the coupling between the coil and the magnet is enhanced, thereby improving the pin's extension and retraction efficiency. For example, the speed and stability of the coil pushing the magnet to extend and retract the pin are increased.

[0039] In some possible implementations, the magnetic drive component includes a coil and a magnet, with the extended magnetic attraction component located on the side of the magnet facing the pin hole. The coil is fixed to the moving platform, and the magnet is fixed to the pin. The coil is annular, and the magnet and coil are coaxially arranged. When the pin is retracted, the ratio of the length of the magnet exposed from the coil to the length of the magnet is within a range of 20% to 60%.

[0040] In this implementation, when the pin is in a retracted state, the ratio of the length of the portion of the magnet exposed from the coil to the length of the magnet can be in the range of 20% to 60%, which is beneficial to improving the effect of driving the magnet to extend the pin after the coil is energized.

[0041] In some possible implementations, when the pin is in the extended state, the ratio of the length of the portion of the magnet exposed from the coil to the length of the magnet is in a range of 50% to 90%.

[0042] In this implementation, when the pin is in the extended state, the ratio of the length of the portion of the magnet exposed from the coil to the length of the magnet can be in the range of 50% to 90%, which is beneficial to improving the effect of driving the magnet to retract the pin after the coil is energized.

[0043] In some possible implementations, the ratio of the outer diameter of the magnet to the outer diameter of the coil is in a range of 40% to 90%.

[0044] In this implementation, the ratio of the outer diameter of the magnet to the outer diameter of the coil can be in the range of 40% to 90%, which can improve the coupling effect between the coil and the magnet, thereby improving the effect of extending and retracting the pin.

[0045] In some possible implementations, the pin is coaxially arranged with the magnet.

[0046] In this implementation, by arranging the magnet and the pin coaxially, when the coil drives the magnet to move, the movement direction of the magnet can be aligned with the axis of the pin, thereby making the movement of the pin driven by the magnet more stable and reducing the resistance brought by the pin to the magnet, which is conducive to the efficient extension and retraction of the pin.

[0047] Wherein, the pin shaft is penetrated by the magnet.

[0048] In this implementation, by passing the magnet through the pin, the stability of the connection between the pin and the magnet can be improved, the overall stiffness of the magnet and the pin can be improved, and the magnet can be set close to the center of the pin. The pin can guide the movement of the magnet, which is beneficial to improving the balance of the movement of the pin driven by the magnet.

[0049] In some possible implementations, the pole face of the magnet is perpendicular to the axis of the pin, and the coil is spaced apart and positioned on either side of the magnet's pole face, with the coil's winding plane parallel to the magnet's pole face. The coil is configured to generate a Lorentz force under the action of the magnet when energized. Within the pin's range of extension and retraction, the magnet and coil are at least partially positioned opposite each other.

[0050] In this implementation, after the coil is energized, it can generate a Lorentz force under the action of the magnetic field of the magnet. Since the coil is fixed to the mounting base, the magnet is pushed out or pulled back under the reaction force of the Lorentz force, thereby realizing the extension and retraction of the pin shaft.

[0051] In some possible implementations, the pole surface of the magnet is perpendicular to the axis of the pin shaft, the coil is spaced apart and arranged on one side of the pole surface of the magnet, and the coil is used to generate a magnetic force along the axis of the pin shaft when energized.

[0052] In this implementation, the coil can generate a magnetic field on the winding surface facing the magnet after being energized. Depending on the direction of the current, the coil can interact with the magnet to generate magnetic repulsion to push the magnet, or generate magnetic attraction to pull the magnet, thereby realizing the extension and retraction of the pin shaft.

[0053] In some possible implementations, the self-locking assembly further includes a mounting base, which is mounted on the moving platform. The mounting base includes a bottom wall, a first side wall, and a second side wall, the bottom wall being mounted on the moving platform, the first side wall and the second side wall being located on the same side of the bottom wall and connected to opposite ends of the bottom wall, the first side wall being closer to the pin hole than the second side wall, the bottom wall, the first side wall, and the second side wall enclosing a mounting space, the mounting space accommodating at least a portion of the magnetic drive component and the pin shaft, wherein the coil is fixed to the bottom wall and / or the second side wall.

[0054] In this implementation, the mounting seat can play a role in stably mounting the magnetic drive component and the pin, and provide stable support for the extension and retraction of the pin.

[0055] In some possible implementations, the first side wall is provided with a first guide hole, and the second side wall is provided with a second guide hole. The first guide hole and the second guide hole are both connected to the installation space. The inner diameter of the first guide hole and the inner diameter of the second guide hole are both larger than the outer diameter of the pin shaft and smaller than the outer diameter of the magnet. The first guide hole and the second guide hole are used to pass through the pin shaft.

[0056] In this implementation, the design of the first guide hole and the second guide hole can guide the extension and retraction of the pin, thereby improving the stability of the extension and retraction of the pin. By setting the inner diameter of the first guide hole to be smaller than the outer diameter of the magnet, when the pin is extended, the first side wall can pass through the limiting magnet, thereby limiting the length of the pin extension to prevent the pin from over-extending and colliding with other components. By setting the inner diameter of the second guide hole to be larger than the outer diameter of the magnet, when the pin is retracted, the second side wall can pass through the limiting magnet, thereby limiting the position of the pin retraction to prevent the pin from falling off through the second limiting hole.

[0057] In some possible implementations, the self-locking assembly further includes a balancing magnetic element, which is disposed on a side of the bottom wall facing away from the installation space. The magnet covers at least a portion of the balancing magnetic element during movement.

[0058] In this implementation, the balancing magnetic attraction component can adsorb the magnet toward the bottom wall to prevent the magnet and the pin from offsetting during movement, thereby improving the stability of the coil-driven magnet to drive the pin movement, and facilitating the pin to align with the pin hole and accurately insert it into the pin hole.

[0059] In some possible implementations, the self-locking assembly further includes a retractable magnetic member, which is used to lock the pin shaft in the moving platform after the pin shaft is retracted and disengaged from the pin hole.

[0060] In this implementation, the retractable magnetic part can attract the magnet after the pin is retracted, so that the pin can maintain a stable retracted state, thereby preventing the pin from affecting the relative movement between the moving platform and the fixed base. In addition, after the coil in the magnetic drive is powered off, although the coil no longer generates a magnetic attraction force on the magnet to pull the pin, the retractable magnetic part can attract the magnet, so that the pin can still maintain a retracted state after the coil is powered off, which is beneficial to saving energy. In addition, when the magnetic drive drives the pin to retract close to the retracted limit position of the pin, the retracted magnetic part can complete the locking of the pin by magnetically attracting the magnet, thereby achieving auxiliary locking of the pin at the retracted limit position. Through the joint action of the extended magnetic part and the retracted magnetic part, the two-speed power-off self-locking of the self-locking component can be achieved, so as to achieve energy saving of the self-locking component.

[0061] In some possible implementations, the self-locking assembly further includes a buffer member, which is disposed around a portion of the pin shaft for insertion into the pin hole.

[0062] In this implementation, the buffer member can reduce the impact force when the pin shaft is inserted into the pin hole, so as to protect the pin shaft and the fixed base and increase the life of the motor.

[0063] In a second aspect, the present application provides a camera module, comprising a lens and a motor according to any one of claims 1 to 4, wherein the lens comprises an optical element and a lens group, the optical element being mounted on a motion stage of the motor, and the lens group being located on the image side of the optical element.

[0064] In this implementation, the optical element is used to change the direction of light so that the light entering through the through hole can be reflected to the image sensor. For example, the optical element may include a prism or a reflector.

[0065] The optical element may include a prism and a lens. The lens of the optical element may be connected to the prism of the optical element and move along with the prism of the optical element, so that the focal length of the lens can be changed when the optical element moves along with the motion stage.

[0066] The lens of the optical element may be located on the object side of the prism of the optical element, or may be located on the image side of the optical element, or the optical element may have multiple lenses, some of which are located on the object side of the prism of the optical element and others are located on the image side of the prism of the optical element.

[0067] In some possible implementations, the lens further includes a first lens group and a second lens group, the first lens group and the second lens group being spaced apart along the direction of motion of a motion stage of a motor. The motion stage is configured to drive the optical element to a first position to receive light passing through the first lens group. The motion stage is further configured to drive the optical element to a second position to receive light passing through the second lens group.

[0068] In this implementation, the motion stage drives the optical element to move, so that the optical element can be combined with different lenses at different positions to form lenses with different focal lengths. For example, in a first position, the first lens group, the optical element, and the lens group can form a first lens with a first focal length; in a second position, the second lens group, the optical element, and the lens group can form a second lens with a second focal length. The first focal length is different from the second focal length. Therefore, by driving the optical element to move to different positions by the motion stage, it is possible to switch between different lenses, for example, to switch between the first lens and the second lens. By analogy, by setting more lens groups, it is also possible to switch between lenses with more focal lengths.

[0069] The first and second lens groups can be mounted on a decorative piece or cover plate and positioned in corresponding through-holes, allowing the optical element to be moved to different through-holes to switch lenses. For example, the first lens group can be mounted in one through-hole, and the second lens group can be mounted in another through-hole.

[0070] The first lens group and the second lens group may be the same or different.

[0071] In a third aspect, the present application provides an electronic device, comprising a housing and a camera module according to claim 1 or 2, wherein the camera module is mounted on the housing.

[0072] In this implementation, a pin inserted into a pin hole achieves physical, mechanical, and stable self-locking. Specifically, the self-locking assembly locks the moving stage to the fixed base, thereby achieving self-locking of the motor and, in turn, stabilizing the lens. This helps improve the reliability of the lens when the electronic device is shaken or dropped. For example, when the pin is inserted into the pin hole, the moving stage and the fixed base are locked, ensuring reliability against manual shaking and a one-meter drop.

[0106] It will be understood that Figures 1A and 1B only schematically illustrate some components included in the electronic device 1000, and the actual shape, actual size, actual position and actual structure of these components are not limited by Figures 1A and 1B. The electronic device 1000 may also include more or fewer components compared to Figures 1A and 1B.

[0107] 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, and the like. The screen 200 may include a translucent panel 2001 and a display screen 2002. The translucent panel 2001 and the display screen 2002 are stacked and fixedly connected. The translucent panel 2001 is primarily used to protect and dustproof the display screen 2002. The material of the translucent 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 may 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 (OLED) display screen, a micro organic light-emitting diode (OLED) display screen, a micro organic light-emitting diode (OLED) display screen, a quantum dot light-emitting diode (QLED) display screen, a liquid crystal display (LCD), etc.

[0108] Exemplarily, 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 decorative element 3003. The cover plate 3001 is located on a 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. Exemplarily, the frame 3002 may be fixed to the cover plate 3001 by adhesive. The frame 3002 may also be integrally molded with the cover plate 3001, i.e., the frame 3002 and the cover plate 3001 form a single, integral structure. The frame 3002 is located between the cover plate 3001 and the light-transmitting panel 2001. The light-transmitting panel 2001 may be fixed to the frame 3002 by adhesive. The light-transmitting panel 2001, the cover plate 3001, and the frame 3002 enclose the internal storage space of the electronic device 1000. This internal space accommodates the display screen 2002. The cover plate 3001 can be made of metal, plastic, glass, or other materials. It can be a single-material plate or a structure composed of multiple panels. The cover plate 3001 has a mounting opening, and the decorative member 3003 covers and is fixed to the mounting opening.

[0109] Illustratively, the camera module 100 is used to capture photos / videos. Illustratively, the camera module 100 is installed within the housing 300, located within the internal storage space of the electronic device 1000. The camera module 100 can function as a rear-facing camera. For example, the light-entering surface of the camera module 100 faces the decorative element 3003. The decorative element 3003 is used to protect the camera module 100.

[0110] In some embodiments, the decorative member 3003 protrudes to the side of the cover plate 3001 away from the light-transmitting panel 2001. In this way, the decorative member 3003 can increase the installation space for the camera module 100 in the thickness direction of the electronic device 1000. In other embodiments, the decorative member 3003 can also be flush with the cover plate 3001 or recessed into the internal storage space of the electronic device 1000.

[0111] The decorative member 3003 is provided with a through hole 3004. Through hole 3004 allows light from a scene to enter the light-entering surface of the camera module 100. In other embodiments, the electronic device 1000 may not include the decorative member 3003. In this case, the cover plate 3001 is no longer provided with a mounting opening, and instead, the through hole 3004 is provided therein, allowing light from a scene to enter the light-entering surface of the camera module 100.

[0112] In some examples, there may be multiple through holes 3004 , and different through holes 3004 may correspond to different lenses. For example, different through holes 3004 may correspond to lenses with different focal lengths.

[0113] In other examples, the number of the through hole 3004 may be one, and different areas of the through hole 3004 may correspond to different lenses. For example, different areas of the through hole 3004 may correspond to lenses 20 with different focal lengths.

[0114] It should be noted that, in the embodiments described below, one through hole 3004 is used to illustrate the configuration of a lens with one focal length.

[0115] In other embodiments, the camera module 100 can also be used as a front-facing camera. For example, the light-entering surface of the camera module 100 faces the light-transmitting panel 2001. The display screen 2002 is provided with a light path avoidance hole. This light path avoidance hole allows scene light to pass through the light-transmitting panel 2001 and then enter the light-entering surface of the camera module 100. In other embodiments, the electronic device 1000 may also include one or more other camera modules (not shown in the figure), which is not strictly limited in the embodiments of the present application.

[0116] In some embodiments, as shown in FIG1B , the electronic device 1000 may further include a circuit board 400 and an image processor 500, wherein the circuit board 400 and the image processor 500 are located in the internal accommodation space of the electronic device 1000, and the image processor 500 is fixed to the circuit board 400 and electrically connected to the circuit board 400. The image processor 500 is communicatively connected to the camera module 100. The image processor 500 is used to obtain image data from the camera module 100 and process the image data. Among them, the communication connection between the camera module 100 and the image processor 500 may include data transmission through electrical connection methods such as wiring, and data transmission may also be achieved through coupling and other methods. It is understandable that the camera module 100 and the image processor 500 may also achieve communication connection through other methods that can achieve data transmission.

[0117] In some embodiments, the electronic device 1000 may further include an analog-to-digital converter (also referred to as an A / D converter, not shown). 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. The image processor 500 then processes the digital image signal and ultimately displays the image or video on the screen 200.

[0118] In some embodiments, the electronic device 1000 may further include a memory (not shown), which is communicatively connected to the image processor 500. The image processor 500 processes the digital image signal and then transfers the image to the memory, so that the image can be retrieved from the memory at any time when the image is needed and displayed on the screen 200. 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.

[0119] In some other embodiments, the electronic device 1000 may not include the screen 200 .

[0120] It is understood that the installation position of the camera module 100 of the electronic device 1000 in the embodiment shown in Figures 1A and 1B is merely illustrative, and the present 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 positions of the electronic device 1000, for example, the camera module 100 may be installed in 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 be rotated, moved or disassembled relative to the terminal body, and the camera module 100 may also be set on the auxiliary component.

[0121] Please refer to Figure 2A and Figure 2B in combination. Figure 2A is a schematic diagram of the partial structure of the electronic device 1000 shown in Figure 1A cut along line AA; Figure 2B is a schematic diagram of the structural layout of the motor 10 in some embodiments of the electronic device 1000 shown in Figure 2A.

[0122] In some embodiments, the camera module 100 may include a lens 20 and a motor 10. The lens 20 may include an optical element 201, a lens group 202, and an image sensor 203. The optical element 201 may be mounted on the motor 10. The optical element 201, the lens group 202, and the image sensor 203 are spaced apart along the optical path of the lens 20.

[0123] Exemplarily, the motor 10 may include a fixed base 1 , a moving platform 2 , a driving component 3 , a self-locking component 4 and a detection component 5 .

[0124] The moving platform 2 can be connected to the fixed base 1, and the moving platform 2 is used to carry the optical element 201. The driving assembly 3 is used to drive the moving platform 2 to drive the optical element 201 to move relative to the fixed base 1. The motor 10 can have a light entrance hole (not shown in the figure), and the axial direction of the light entrance hole intersects with the movement direction of the moving platform 2. At this time, the camera module 100 is a periscope camera module 100. There are multiple through holes 3004 on the decorative part 3003, and the arrangement direction of the multiple through holes 3004 is the same as the movement direction of the moving platform 2.

[0125] In this embodiment, the moving platform 2 can drive the optical element 201 to move relative to the fixed base 1 to change the position of the optical element 201, thereby changing the through hole 3004 corresponding to the optical element 201, and the distance between the optical element 201 and the lens group 202, thereby realizing the change of the focal length of the camera module 100, that is, realizing the switching of the lens, for example, realizing the switching between telephoto shooting and macro shooting.

[0126] The light entrance hole of the motor 10 can be provided corresponding to the through hole 3004 to allow light entering through the through hole 3004 to pass through. The light entrance hole of the motor 10 can be an open hole, or an unenclosed area of ​​the motor 10, as long as it can allow light entering through the through hole 3004 to pass through.

[0127] The load capacity of the motion platform 2 can be greater than or equal to 2000 mg. In this embodiment, the load capacity of the motion platform 2 refers to the weight that the motion platform 2 can bear. That is, the motion platform 2 provided in the embodiment of the present application can drive an optical element 201 weighing greater than or equal to 2000 mg to move relative to the fixed base 1, achieving super-heavy load motion. For example, the load capacity of the motion platform 2 can be 2000 mg, 2500 mg, or 3000 mg.

[0128] It should be noted that the load capacity of the moving platform 2 can be greater than or equal to 2000 mg, which means that the moving platform 2 has a large load capacity, and does not limit the optical element 201 carried by the moving platform 2. It can be understood that the moving platform 2 can also carry lighter optical elements 201, such as optical elements 201 weighing less than 2000 mg.

[0129] The optical element 201 is used to change the direction of light so that the light entering through the through hole 3004 can be reflected to the image sensor 203. For example, the optical element 201 may include a prism or a reflector.

[0130] In some examples, the optical element 201 may include a prism and a lens. The lens of the optical element 201 may be connected to the prism of the optical element 201 and move along with the prism of the optical element 201, so that the focal length of the lens 20 can be changed when the optical element 201 moves along with the motion stage 2.

[0131] In which, the lens of the optical element 201 can be located on the object side of the prism of the optical element 201, or, it can be located on the image side of the optical element 201, or the optical element 201 has multiple lenses, some of which are located on the object side of the prism of the optical element 201, and the other parts are located on the image side of the prism of the optical element 201.

[0132] It should be noted that by changing the distance between the optical element 201 and the lens group 202 , the focal length of the lens 20 can be changed, thereby achieving switching of the lens 20 .

[0133] It should be noted that, in this embodiment, the optical element 201 may also be a combination of a reflector and a lens, which is not limited here.

[0134] In other examples, the lens 20 may further include a first lens group 204 and a second lens group 205. The first lens group 204 and the second lens group 205 may be spaced apart along the direction of motion of the motion stage 2. The motion stage 2 is configured to move the optical element 201 to a first position to receive light passing through the first lens group 204. The motion stage 2 is also configured to move the optical element 201 to a second position to receive light passing through the second lens group 205.

[0135] In this embodiment, the motion stage 2 drives the optical element 201 to move, so that the optical element 201 can be combined with different lenses at different positions to form lenses 20 with different focal lengths. For example, in the first position, the first lens group 204, the optical element 201, and the lens group 202 can form a first lens with a first focal length; in the second position, the second lens group 205, the optical element 201, and the lens group 202 can form a second lens with a second focal length. The first focal length is different from the second focal length. Therefore, by driving the optical element 201 to move to different positions by the motion stage 2, it is possible to switch between different lenses 20, for example, to switch between the first lens and the second lens. By analogy, by setting more lens groups, it is also possible to switch between lenses 20 with more focal lengths.

[0136] The first lens group 204 and the second lens group 205 can be mounted on the decorative member 3003 or the cover plate 3001 and arranged corresponding to the through holes 3004, so that the optical element 201 can be moved to different through holes 3004 to achieve switching of the lens 20. For example, the first lens group 204 can be mounted in one through hole 3004, and the second lens group 205 can be mounted in another through hole 3004.

[0137] The first lens group 204 and the second lens group 205 may be the same or different.

[0138] The optical element 201 may include a prism or a reflector and a lens, or may include only a prism or a reflector.

[0139] The fixed base 1 may be provided with a plurality of pin holes 11, which are spaced apart along the direction of movement of the moving platform 2 relative to the fixed base 1. Each pin hole 11 may correspond to a through hole 3004 on the cover 3001. A self-locking assembly 4 may be mounted on the moving platform 2. The self-locking assembly 4 may include a pin 41 that can extend and retract relative to the moving platform 2. When the pin 41 extends, it can extend into the pin hole 11 to lock the moving platform 2 and the fixed base 1. When the pin 41 retracts, it can disengage from the pin hole 11 to unlock the moving platform 2 and the fixed base 1.

[0140] It should be noted that a pin hole 11 can be set corresponding to a through hole 3004 on the cover plate 3001, which means that when the pin shaft 41 is inserted into the pin hole 11, light can be incident on the optical element 201 through the through hole 3004 corresponding to the pin hole 11 in which the pin shaft 41 is inserted, and reflected to the image sensor 203 through the optical element 201.

[0141] In this embodiment, the insertion of the pin 41 into the pin hole 11 achieves a physical, mechanical, and stable self-locking mechanism. Specifically, the self-locking assembly 4 locks the moving stage 2 to the fixed base 1, thereby achieving self-locking of the motor 10 and, in turn, stabilizing the lens 20. This improves the reliability of the lens 20 when the electronic device 1000 is shaken or dropped. For example, when the pin 41 is inserted into the pin hole 11, the moving stage 2 and the fixed base 1 are locked, ensuring reliability against manual shaking and a one-meter drop.

[0142] The pin 41 can extend by at least 900 μm to improve the stable locking of the pin 41 and the pin hole 11 .

[0143] Among them, one through hole 3004 can be provided corresponding to a plurality of pin holes 11 to improve the locking stability of the moving platform 2 and the fixed base 1 at each through hole 3004 .

[0144] In the direction of motion of the movable stage 2 relative to the fixed base 1, the spacing between two pin holes 11 at the ends of the plurality of pin holes 11 is greater than or equal to 9000 μm. In other words, the spacing between two through holes 3004 at the ends of the plurality of through holes 3004 is greater than or equal to 9000 μm along the direction of motion of the movable stage 2 relative to the fixed base 1.

[0145] In this embodiment, the motor 10 can drive the optical element 201 to achieve long-distance movement through the motion platform 2, providing sufficient layout space for lenses 20 with different focal lengths, reducing or even avoiding structural layout interference between lenses 20 with different focal lengths, and facilitating the switching of lenses 20 with different focal lengths.

[0146] Among them, the detection component 5 is used to detect the position of the moving platform 2 relative to the fixed base 1, so as to assist in aligning the pin shaft 41 and the pin hole 11, which is beneficial to the accuracy of inserting the pin shaft 41 into the pin hole 11, reducing or even avoiding the accidental collision of the pin shaft 41 with the fixed base 1 when extending, and thus helping to improve the service life of the motor 10.

[0147] It can be understood that in some other embodiments, the pin hole 11 can be provided on the moving platform 2 , and correspondingly, the self-locking component 4 is provided on the fixed base 1 .

[0148] In some embodiments, the pin holes 11 can be provided on both sides of the moving platform 2, the self-locking assembly 4 is provided corresponding to the pin holes 11, and the driving assembly 3 can be provided on the bottom side of the moving platform 2. In other words, the pin shaft 41 in the self-locking assembly 4 extends toward both sides of the moving platform 2.

[0149] In this embodiment, by arranging the pin hole 11 and the drive assembly 3 on different sides of the motion platform 2, it is possible to prevent the extension of the pin shaft 41 in the self-locking assembly 4 from interfering with the installation space of the drive assembly 3. In addition, it is possible to avoid the motion platform 2 being excessively large on one side due to the installation of too many components, thereby improving space utilization.

[0150] Illustratively, two groups of pin holes 11 are provided corresponding to each through hole 3004 , and the two groups of pin holes 11 are symmetrically arranged on both sides of the corresponding moving platform 2 , which is beneficial to improving the stability of the self-locking component 4 locking the moving platform 2 and the fixed base 1 .

[0151] The detection component 5 can be adaptively arranged according to the installation gap of the motor 10 to improve the space utilization of the motor 10.

[0152] Please refer to Figure 3A and Figure 3B in combination. Figure 3A is a structural schematic diagram of the motor 10 in the electronic device 1000 shown in Figure 2A in some embodiments; Figure 3B is a partial structural decomposition schematic diagram of the motor 10 shown in Figure 3A in some embodiments.

[0153] For ease of illustration, in the embodiment of the present application, a rectangular coordinate system is established with the direction of motion of the moving stage 2 relative to the fixed base 1 as the X-axis, the width direction of the motor 10 as the Y-axis, and the thickness direction of the motor 10 as the Z-axis. It is understood that in other embodiments, the coordinate system can also be established with other references, which is not limited here.

[0154] In some embodiments, the motor 10 may further include a control circuit 6, which may be mounted on the fixed base 1. The control circuit 6 may be electrically connected to the drive assembly 3. In this embodiment, the control circuit 6 is used to control the drive assembly 3 to drive the motion stage 2 to move relative to the fixed base 1.

[0155] Exemplarily, the control circuit 6 may also be electrically connected to the detection component 5 .

[0156] In this embodiment, the control circuit 6 is also used to receive the position of the moving platform 2 detected by the detection component 5, so as to assist in determining whether the moving platform 2 has moved to the set position, and whether the pin shaft 41 is aligned with the pin hole 11, which is beneficial to improving the accuracy of the pin shaft 41 being inserted into the pin hole 11.

[0157] The control circuit 6 can also be electrically connected to the self-locking component 4 to control the extension and retraction of the pin 41 in the self-locking component 4 .

[0158] It should be noted that the control instructions and signal processing of the control circuit 6 can be implemented by a processor in the electronic device 1000 , or by a control chip integrated in the control circuit 6 .

[0159] Please refer to Figures 3B to 4B in combination. Figure 4A is a structural schematic diagram of the fixed base 1 in the motor 10 shown in Figure 3A in some embodiments; Figure 4B is a partial structural decomposition schematic diagram of the fixed base 1 shown in Figure 4A in some embodiments.

[0160] In some embodiments, the fixed base 1 may include a first portion 1a and a second portion 1b, wherein the first portion 1a of the fixed base 1 is connected to the second portion 1b of the fixed base 1. The first portion 1a of the fixed base 1 may be connected to the moving platform 2, and the second portion 1b of the fixed base 1 may be provided with a pin hole 11.

[0161] Exemplarily, the first portion 1 a of the fixed base 1 may have an accommodating space 12 , and the accommodating space 12 may accommodate the moving platform 2 , the self-locking component 4 , the detection component 5 and the driving component 3 .

[0162] The first portion 1 a of the fixed base 1 may be mounted with a guide member 13 and connected to the moving platform 2 via the guide member 13 , so that the moving platform 2 can move relative to the fixed base 1 along the extension direction of the guide member 13 .

[0163] It should be noted that the drawings in this application illustrate linear displacement and do not limit the motion of the moving platform 2 relative to the fixed base 1. This motion can be, but is not limited to, linear or curved motion. In other embodiments, the guide member 13 can also be curved or shaped, as long as it can guide the moving platform 2. In other words, the motor 10 provided in this embodiment of the application can also be used in scenarios involving large-angle rotation.

[0164] For example, the first portion 1a of the fixed base 1 and the second portion 1b of the fixed base 1 may be connected along the thickness direction of the motor 10. The top side of the second portion 1b of the fixed base 1 may cover a portion of the moving stage 2.

[0165] In this embodiment, the first part 1a of the fixed base 1 is connected to the second part 1b of the fixed base 1 along the thickness direction of the motor 10, which is conducive to the installation of the moving platform 2, the self-locking component 4, the detection component 5 and the driving component 3 in the accommodating space 12. Specifically, before the first part 1a of the fixed base 1 is connected to the second part 1b of the fixed base 1, the moving platform 2, the self-locking component 4, the detection component 5 and the driving component 3 can be installed in the accommodating space 12, and then the second part 1b of the fixed base 1 is fixedly connected to the first part 1a of the fixed base 1 to achieve at least partial sealing of the moving platform 2, the self-locking component 4, the detection component 5 and the driving component 3.

[0166] Among them, after the first part 1a of the fixed base 1 is connected to the second part 1b of the fixed base 1, the first part 1a of the fixed base 1 can block the side of the pin hole 11 away from the accommodating space 12, so as to achieve sealing of the outside of the pin hole 11 and prevent external impurities from entering the accommodating space 12 through the outside of the pin hole 11, thereby achieving dust prevention.

[0167] In some other embodiments, the pin hole 11 may be provided in the first portion 1 a of the fixed base 1 , and / or the guide member 13 may be provided in the second portion 1 b of the fixed base 1 .

[0168] Please refer to FIG. 2A and FIG. 5A in combination. FIG. 5A is a schematic structural diagram of the moving platform 2 in the motor 10 shown in FIG. 3A in some embodiments.

[0169] In some embodiments, the moving stage 2 has a supporting surface 21 facing away from the bottom wall 14 of the fixed base 1 and tilted relative to the bottom wall 14 of the fixed base 1 . The supporting surface 21 is used to support the optical element 201 .

[0170] In this embodiment, because optical element 201 needs to redirect light incident through through-hole 3004 in order to reflect the incident light toward image sensor 203, optical element 201 is required to be provided with a reflective surface that is inclined relative to bottom wall 14 of fixed base 1. Motion stage 2 is contoured to optical element 201, thereby designing an inclined support surface 21 for mounting optical element 201. Support surface 21 is configured to correspond to the reflective surface of optical element 201, thereby improving the mounting stability of optical element 201. Furthermore, by mounting optical element 201 on inclined support surface 21, positioning it in the gap between optical element 201 and fixed base 1, the space utilization of motor 10 is improved.

[0171] The optical element 201 may be installed on the optical element 201 by, but not limited to, plugging, snapping, bonding, etc.

[0172] Please refer to Figures 5A to 6. Figure 5B is a structural diagram of the motion platform 2 shown in Figure 5A from another perspective; Figure 6 is a structural diagram of the motion platform 2 shown in Figure 5B installed with the self-locking component 4.

[0173] In some embodiments, the moving platform 2 may have a receiving space 22 , which is located between the carrying surface 21 and the bottom wall 14 of the fixed base 1 and is used to receive the self-locking component 4 .

[0174] In this embodiment, by utilizing the portion of the moving platform 2 between the supporting surface 21 and the fixed base 1 to provide a receiving space 22, the space utilization of the moving platform 2 is improved. By accommodating the self-locking assembly 4 in the receiving space 22 of the moving platform 2, the size of the motor 10 is reduced, facilitating a slimmer design for the motor 10. Furthermore, since the self-locking assembly 4 moves with the moving platform 2, installing the self-locking assembly 4 within the interior space of the moving platform 2 also improves the stability of the self-locking assembly 4 and the moving platform 2.

[0175] Illustratively, the moving platform 2 may have a reinforcing rib 23 , which is located in the inner space of the moving platform 2 to separate the inner space of the moving platform 2 into two receiving spaces 22 for respectively receiving the two self-locking components 4 .

[0176] In this embodiment, the reinforcement ribs 23 are provided to not only enhance the structural strength of the moving platform 2 but also to separate the two self-locking components 4 to reduce interference between the two self-locking components 4 .

[0177] The moving platform 2 is provided with an opening 24 communicating with the receiving space 22 , and the opening 24 is provided corresponding to the pin 41 of the self-locking component 4 , so that the pin 41 of the self-locking component 4 can extend and retract through the opening 24 .

[0178] Please refer to Figures 7A to 7C in combination. Figure 7A is a structural schematic diagram of the self-locking component 4 in the motor 10 shown in Figure 3A in some embodiments; Figure 7B is a structural schematic diagram of the self-locking component 4 shown in Figure 7A in some embodiments; Figure 7C is a structural schematic diagram of the self-locking component 4 shown in Figure 7A cut along line BB in some embodiments.

[0179] In some embodiments, the self-locking assembly 4 may further include a magnetic drive component 42 , an extending magnetic component 43 , a mounting seat 44 , a retracting magnetic component 45 , a balancing magnetic component 46 and a buffer component 47 .

[0180] Exemplarily, the mounting base 44 can be mounted on the moving platform. The mounting base 44 may include a bottom wall 441, a first side wall 442, and a second side wall 443. The bottom wall 441 is mounted on the moving platform. The first side wall 442 and the second side wall 443 are located on the same side of the bottom wall 441 and connected to opposite ends of the bottom wall 441. The first side wall 442 is closer to the pin hole 11 than the second side wall 443. The bottom wall 441, the first side wall 442, and the second side wall 443 are surrounded to form an installation space 444. The installation space 444 accommodates at least a portion of the magnetic drive component 42 and the pin shaft 41.

[0181] In this embodiment, the mounting seat 44 can play a role in stably mounting the magnetic drive component 42 and the pin shaft 41 , and provides stable support for the extension and retraction of the pin shaft 41 .

[0182] Among them, the first side wall 442 can be provided with a first guide hole 4421, and the second side wall 443 can be provided with a second guide hole 4431. The first guide hole 4421 and the second guide hole 4431 are both connected to the installation space 444. The inner diameter of the first guide hole 4421 and the inner diameter of the second guide hole 4431 are both larger than the outer diameter of the pin shaft 41. The first guide hole 4421 and the second guide hole 4431 are used to pass through the pin shaft 41.

[0183] In this embodiment, the design of the first guide hole 4421 and the second guide hole 4431 can serve as a guide for the extension and retraction of the pin shaft 41, thereby improving the stability of the extension and retraction of the pin shaft 41.

[0184] The cross-sectional shape of the first guide hole 4421 can be circular, elliptical, V-shaped, U-shaped, etc. The cross-sectional shape of the second guide hole 4431 can be circular, elliptical, V-shaped, U-shaped, etc.

[0185] The second side wall 443 and the bottom wall 441 may be a split structure, that is, the second side wall 443 may be detachably connected to the bottom wall 441 .

[0186] In this embodiment, the second side wall 443 is detachably connected to the bottom wall 441 so that the magnetic drive component 42 and the pin shaft 41 can be installed in the installation space 444 before the second side wall 443 is installed on the bottom wall 441. The installation of the second side wall 443 on the bottom wall 441 can fix the magnetic drive component 42 and the pin shaft 41, which is beneficial to improving the stability of the extension and retraction of the pin shaft 41.

[0187] Please refer to FIG. 7A , FIG. 7C and FIG. 8 . FIG. 8 is a schematic structural diagram of the motor 10 shown in FIG. 3A when the pin 41 is retracted, taken along line CC in some embodiments.

[0188] In some embodiments, the magnetic drive component 42 can be used to drive the pin shaft 41 to extend relative to the moving platform 2 and insert into the pin hole 11 to lock the moving platform 2 and the fixed base 1. The magnetic drive component 42 is also used to drive the pin shaft 41 to retract relative to the moving platform 2 to disengage from the pin hole 11 to unlock the moving platform 2 and the fixed base 1.

[0189] Exemplarily, the magnetic drive component 42 may include a coil 421 and a magnet 422. The coil 421 may be fixed to the motion platform 2 by being fixed to the mounting base 44, and the magnet 422 may be fixedly connected to the pin 41. The coil 421 is configured to pass a first current through the magnet 422 to extend the pin 41, and the coil 421 is further configured to pass a second current through the magnet 422 to retract the pin 41. The direction of the second current is opposite to that of the first current.

[0190] In this embodiment, the extension and retraction of the driving pin 41 can be achieved by energizing and reversing the coil 421 , so that the locking and unlocking of the moving platform 2 and the fixed base 1 are quick.

[0191] In addition, in this embodiment, by setting the coil 421 fixed and the magnet 422 moving relative to the coil 421, that is, a fixed coil and moving magnet design, it is beneficial to the circuit connection of the coil 421, avoiding the movement of the coil 421 pulling the wiring harness connection of the coil 421, and is beneficial to improving the stability of the coil 421 driving the magnet 32.

[0192] In some other embodiments, the magnet 422 can be fixedly mounted on the mounting base 44, and the coil 421 can be fixedly connected to the pin 41, thereby realizing a fixed magnet moving coil design, which is beneficial to reducing the driving force required to drive the pin 41, thereby achieving energy saving and faster extension and retraction of the pin 41.

[0193] In other embodiments, the magnetic drive member 42 may be used only to drive the pin 41 to extend relative to the moving platform 2 and insert into the pin hole 11, thereby locking the moving platform 2 and the fixed base 1. The retraction of the pin 41 can be achieved by other means. For example, an elastic member can be provided to elastically connect the pin 41 and the mounting base 44. When the coil 421 is energized, it can drive the magnet 422 to compress the elastic member and drive the pin 41 to extend. When the coil 421 is de-energized, the elastic member drives the pin 41 to retract due to its elastic restoring force.

[0194] In the embodiment of the present application, in the state shown in Figures 7A, 7C, and 8, the magnetic drive member 42 can drive the pin shaft 41 to extend and insert into the pin hole 11 on the fixed base 1, thereby converting to the state shown in Figures 9A to 10, thereby locking the moving platform 2 and the fixed base 1. In addition, in the state shown in Figures 9A to 10, the magnetic drive member 42 can also drive the pin shaft 41 to retract and disengage from the pin hole 11, thereby converting to the state shown in Figures 7A, 7C, and 8, thereby unlocking the moving platform 2 and the fixed base 1.

[0195] Please refer to Figures 9A to 10 in combination. Figure 9A is a structural schematic diagram of some embodiments after the pin shaft 41 in the self-locking component 4 shown in Figure 3A is extended; Figure 9B is a structural schematic diagram of some embodiments after the self-locking component 4 shown in Figure 9A is cut along line DD; Figure 10 is a structural schematic diagram of some embodiments when the motor 10 shown in Figure 3A is cut along line CC when the pin shaft 41 is extended.

[0196] In some embodiments, the outer diameter of the portion of the pin shaft 41 inserted into the pin hole 11 may be smaller than the inner diameter of the pin hole 11 .

[0197] In this embodiment, the outer diameter of the portion of the pin shaft 41 inserted into the pin hole 11 is designed to be smaller than the inner diameter of the pin hole 11, so as to provide a radial margin space for the pin shaft 41, thereby reducing or even avoiding the risk of the pin shaft 41 colliding with the fixed base 1 during the process of inserting the pin shaft 41 into the pin hole 11.

[0198] For example, the buffer member 47 may be disposed around the portion of the pin shaft 41 for inserting into the pin hole 11 .

[0199] In this embodiment, the buffer member 47 can reduce the impact force when the pin shaft 41 is inserted into the pin hole 11 , so as to protect the pin shaft 41 and the fixed base 1 and increase the service life of the motor 10 .

[0200] The outer diameter of the buffer 47 may be smaller than the inner diameter of the pin hole 11 to provide a radial margin for the buffer 47 , thereby reducing or even preventing the pin shaft 41 from colliding with the fixed base 1 and causing shaking during the insertion of the pin hole 11 .

[0201] The material of the buffer member 47 may include rubber, silicone and other materials having a buffering effect.

[0202] In some embodiments, the extended magnetic member 43 may be mounted on the mounting base 44 and located on a side of the pin shaft 41 facing the pin hole 11 .

[0203] In this embodiment, the extended magnetic component 43 can magnetically attract the magnet 422 after the pin shaft 41 is extended, so that the pin shaft 41 can maintain a stable state of being inserted into the pin hole 11, thereby improving the stability of the locking motion carrier 2 and the fixed base 1. In addition, after the coil 421 in the magnetic drive component 42 is powered off, although the coil 421 no longer generates a magnetic thrust on the magnet 422 to push the pin shaft 41, the extended magnetic component 43 can magnetically attract the magnet 422, so that the pin shaft 41 can still remain inserted into the pin hole 11, which is beneficial to saving energy. In addition, when the magnetic drive component 42 drives the pin shaft 41 to extend close to the extended limit position of the pin shaft 41, the extended magnetic component 43 can complete the locking of the pin shaft 41 by magnetically attracting the magnet 422, thereby achieving auxiliary locking of the pin shaft 41 at the extended limit position.

[0204] Exemplarily, the protruding magnetic member 43 may be mounted on the first side wall 442 , and the protruding magnetic member 43 may be disposed around the first guide hole 4421 to avoid structural interference between the protruding magnetic member 43 and the pin shaft 41 .

[0205] The extended magnetic member 43 is arranged on the surface of the first side wall 442 away from the second side wall 443 to avoid collision between the magnet 422 and the extended magnetic member 43 when the pin shaft 41 is extended, thereby improving the service life of the extended magnetic member 43 and the magnet 422.

[0206] The extended magnetic member 43 may have magnetic force, or the extended magnetic member 43 may have magnetic conductivity.

[0207] In an embodiment of the present application, in the states shown in Figures 7A, 7C and 8, the driving component 3 can also drive the moving platform 2 to move so that the pin shaft 41 is set corresponding to another through hole, and after the pin shaft 41 is set corresponding to another through hole, the magnetic drive component 42 can drive the pin shaft 41 to extend and insert into the pin hole 11 on the fixed base 1, thereby locking the moving platform 2 and the fixed base 1, for example, realizing the locking of the moving platform 2 and the fixed base 1 in the position shown in Figures 11A and 11B.

[0208] Please refer to Figures 2A, 11A and 11B in combination. Figure 11A is a structural schematic diagram of the moving platform 2 in the motor 10 shown in Figure 3A moving to another position in some embodiments; Figure 11B is a structural schematic diagram of the motor 10 shown in Figure 11A in some embodiments when the pin shaft 41 is extended along line EE.

[0209] In some embodiments, the self-locking assembly 4 can lock the moving platform 2 and the fixed base 1 at different positions.

[0210] In this embodiment, driven by the driving component 3, the moving platform 2 can move relative to the fixed base 1, so that the pin shaft 41 of the self-locking component 4 corresponds to different pin holes 11 settings, and the pin shaft 41 is inserted into the small holes at different positions to enable the self-locking component 4 to lock the moving platform 2 and the fixed base 1 at different positions, so that the camera module 100 can be locked under different focal length lenses 20, providing stability of the lens 20 in the camera module 100.

[0211] Please refer again to Figures 7B to 8. In some embodiments, the coil 421 can be fixedly engaged with the mounting base 44. The bottom wall 441 of the mounting base 44 can be provided with a mounting groove 4411. The mounting groove 4411 is recessed in the bottom wall 441 so that the mounting groove 4411 is close to the inner side wall of the first side wall 442 to form a limiting step. By arranging the coil 421 corresponding to the mounting groove 4411, the second side wall 443 and the bottom wall 441 can jointly engage and fix the coil 421 to the mounting groove 4411, thereby achieving the limited fixation of the coil 421 in the axial direction of the pin 41, so as to prevent the coil 421 from moving relative to the mounting base 44 after power is supplied.

[0212] Among them, the second side wall 443 can be provided with a limit block 4432, and the limit block 4432 can be protruded on the surface of the second side wall 443 facing the first side wall 442. The limit block 4432 can limit the coil 421, and realize the limit fixation of the coil 421 in the radial direction of the pin shaft 41 to avoid the coil 421 from shaking relative to the mounting seat 44 after being energized. Therefore, the joint limiting effect of the limit block 4432 and the mounting groove 4411 can further improve the stability of the installed coil 421.

[0213] In other embodiments, the coil 421 may be bonded to the bottom wall 441 and / or the second side wall 443 to achieve fixation of the coil 421 in a simple fixing manner.

[0214] Illustratively, the inner diameters of the first guide hole 4421 and the second guide hole 4431 may both be smaller than the outer diameter of the magnet 422 .

[0215] In this embodiment, by setting the inner diameter of the first guide hole 4421 to be smaller than the outer diameter of the magnet 422, the first side wall 442 can pass through the limiting magnet 422 when the pin 41 is extended, thereby limiting the extension length of the pin 41 and preventing the pin 41 from overextending and colliding with other components. By setting the inner diameter of the second guide hole 4431 to be larger than the outer diameter of the magnet 422, the second side wall 443 can pass through the limiting magnet 422 when the pin 41 is retracted, thereby limiting the retracted position of the pin 41 and preventing the pin 41 from falling off through the second limiting hole.

[0216] In some embodiments, the retractable magnetic member 45 can be mounted on the mounting base 44 and located on a side of the magnet 422 facing away from the protruding magnetic member 43 .

[0217] In this embodiment, the retracting magnetic component 45 can magnetically attract the magnet 422 after the pin 41 is retracted, so that the pin 41 can maintain a stable retracted state, thereby preventing the pin 41 from affecting the relative movement between the moving platform 2 and the fixed base 1. In addition, after the coil 421 in the magnetic drive component 42 is powered off, although the coil 421 no longer generates a magnetic attraction force on the magnet 422 to pull the pin 41, since the retracting magnetic component 45 can magnetically attract the magnet 422, the pin 41 can still maintain a retracted state after the coil 421 is powered off, which is beneficial to saving energy. In addition, when the magnetic drive component 42 drives the pin 41 to retract close to the retracted limit position of the pin 41, the retracting magnetic component 45 can complete the locking of the pin 41 through the magnetic attraction magnet 422, thereby achieving auxiliary locking of the pin 41 at the retracted limit position. Through the combined action of the extended magnetic member 43 and the retracted magnetic member 45 , two-stage power-off self-locking of the self-locking assembly 4 can be achieved, thereby realizing energy saving of the self-locking assembly 4 .

[0218] Exemplarily, the retractable magnetic member 45 can be installed on the second side wall 443 , and the retractable magnetic member 45 can be arranged around the second guide hole 4431 to avoid structural interference between the retractable magnetic member 45 and the pin shaft 41 .

[0219] The retractable magnetic member 45 is arranged on the surface of the second side wall 443 away from the first side wall 442 to avoid collision between the magnet 422 and the retractable magnetic member 45 when the pin shaft 41 is retracted, thereby improving the service life of the retractable magnetic member 45 and the magnet 422.

[0220] The retractable magnetic member 45 may have magnetic force, or the retractable magnetic member 45 may have magnetic conductivity.

[0221] In some embodiments, the balancing magnetic component 46 may be disposed on the bottom wall 441 , and the magnet 422 covers at least a portion of the balancing magnetic component 46 during movement.

[0222] In this embodiment, the balancing magnetic attraction part 46 can adsorb the magnet 422 toward the bottom wall 441 to prevent the magnet 422 and the pin shaft 41 from offsetting during movement, thereby improving the stability of the coil 421 driving the magnet 32 ​​to drive the pin shaft 41 to move, and is conducive to the pin shaft 41 to align with the pin hole 11 and accurately insert it into the pin hole 11.

[0223] Among them, the balancing magnetic component 46 can be arranged on the side of the bottom wall 441 away from the installation space 444 to avoid the balancing magnetic component 46 occupying the space of the installation space 444, thereby avoiding the balancing magnetic component 46 from occupying the movement space of the magnet 422 or the pin shaft 41, and avoiding the balancing magnetic component 46 from colliding with the magnet 422 or the pin shaft 41, thereby improving the service life of the balancing magnetic component 46.

[0224] For example, a groove may be provided on a surface of the bottom wall 441 facing away from the installation space 444 to accommodate the balancing magnetic element 46 .

[0225] In some embodiments, the coil 421 can be annular, and the magnet 422 is coaxially arranged with the coil 421. When the pin 41 is in the retracted state, the end of the magnet 422 away from the extended magnetic member 43 is located inside the coil 421, and the end of the magnet 422 near the extended magnetic member 43 is exposed from the coil 421. When the pin 41 is in the extended state, the end of the magnet 422 away from the extended magnetic member 43 is located inside the coil 421.

[0226] In this embodiment, the magnetic drive element 42 has a cannon-like structure to implement a dynamic magnetic ejection drive design with an outer coil 421 and an inner magnet 422. By designing so that the magnet 422 is partially exposed from the coil 421 when the pin 41 is in both the extended and retracted states, the coupling between the coil 421 and the magnet 422 is enhanced, thereby improving the effectiveness of extending and retracting the pin 41. For example, the speed and stability of the coil 421 pushing the magnet 422 to drive the pin 41 to extend and retract are increased.

[0227] When the pin 41 is in the retracted state, the ratio of the length of the portion of the magnet 422 exposed from the coil 421 to the length of the magnet 422 can be in the range of 20% to 60%, which is beneficial for improving the effect of driving the magnet 32 ​​to extend the pin 41 after the coil 421 is energized. For example, when the pin 41 is in the retracted state, the ratio of the length of the portion of the magnet 422 exposed from the coil 421 to the length of the magnet 422 can be 20%, 30%, 35%, 40%, 45%, 55%, 60%, or other values ​​between 20% and 60%.

[0228] When the pin 41 is in the extended state, the ratio of the length of the portion of the magnet 422 exposed from the coil 421 to the length of the magnet 422 can be in the range of 50% to 90%, which is conducive to improving the effect of driving the magnet 32 ​​to retract the pin 41 after the coil 421 is energized. For example, when the pin 41 is in the extended state, the ratio of the length of the portion of the magnet 422 exposed from the coil 421 to the length of the magnet 422 can be 50%, 60%, 70%, 75%, 80%, 85%, 90%, or other values ​​between 50% and 90%.

[0229] The ratio of the outer diameter of the magnet 422 to the outer diameter of the coil 421 can be in the range of 40% to 90%, which can improve the coupling effect between the coil 421 and the magnet 422, thereby improving the effect of extending and retracting the pin 41. For example, the ratio of the outer diameter of the magnet 422 to the outer diameter of the coil 421 can be 40%, 50%, 60%, 65%, 70%, 75%, 85%, 90%, or other values ​​between 40% and 90%.

[0230] In some embodiments, the magnet 422 may be coaxially disposed with the pin 41 .

[0231] In this embodiment, by coaxially arranging the magnet 422 and the pin 41, when the coil 421 drives the magnet 32 ​​to move, the movement direction of the magnet 422 can be aligned with the axis of the pin 41, thereby making the movement of the pin 41 driven by the magnet 422 more stable and reducing the resistance brought by the pin 41 to the magnet 422, which is conducive to the efficient extension and retraction of the pin 41.

[0232] For example, the pin 41 may be provided with a magnet 422 .

[0233] In this embodiment, by passing the magnet 422 through the pin 41, the stability of the connection between the pin 41 and the magnet 422 can be improved, the overall stiffness of the magnet 422 and the pin 41 can be improved, and the magnet 422 can be set close to the center of the pin 41. The pin 41 can guide the movement of the magnet 422, which is beneficial to improving the balance of the movement of the pin 41 driven by the magnet 422.

[0234] The pin 41 may include a first portion 41a, a second portion 41b, and a third portion 41c connected in sequence along the direction from the second side wall 443 to the first side wall 442. The outer diameter of the second portion 41b of the pin 41 may be greater than the outer diameter of the first portion 41a of the pin 41.

[0235] In this embodiment, by setting the outer diameter of the second part 41b of the pin 41 to be larger than the outer diameter of the first part 41a of the pin 41, the second part 41b of the pin 41 can form a limit for the magnet 422 at the connection between the first part 41a of the pin 41 and the second part 41b of the pin 41, which is beneficial to the stable connection and installation of the pin 41 and the magnet 422, and reduces the risk of the magnet 422 falling off after the pin 41 is extended and retracted multiple times.

[0236] The outer diameter of the second portion 41 b of the pin 41 may be greater than the outer diameter of the third portion 41 c of the pin 41 , and the buffer member 47 may be sleeved on the third portion 41 c of the pin 41 .

[0237] In this embodiment, by setting the outer diameter of the second part 41b of the pin 41 to be larger than the outer diameter of the third part of the pin, so that at the connection between the second part 41b of the pin 41 and the third part 41c of the pin 41, the second part 41b of the pin 41 can form a limit for the buffer 47, which is beneficial to the stable connection and installation of the buffer 47 and the pin 41, and reduces the risk of the buffer 47 falling off after the pin 41 is extended and retracted multiple times.

[0238] It should be noted that the shapes of the pin 41, magnet 422 and coil 421 in the embodiments of the drawings of this application are only for illustration and do not limit the shapes of the pin 41, magnet 422 and coil 421. As long as the pin 41 and the magnet 422 can be connected in coordination and the magnet 422 and the coil 421 can be coupled, it will be sufficient.

[0239] The cross-sectional shape of the pin 41 may be, but is not limited to, circular, square, or prismatic.

[0240] The cross-sectional shape of the magnet 422 may be, but is not limited to, circular, square, or prismatic.

[0241] The cross-sectional shape of the coil 421 may be, but is not limited to, circular, square, or prismatic.

[0242] Please refer to Figure 2B, Figure 12A and Figure 12B in combination. Figure 12A is a structural schematic diagram of the second part 1b of the fixed base 1 in the motor 10 shown in Figure 3A in some embodiments for installing the magnetic grid 52; Figure 12B is an installation schematic diagram of the self-locking component 4, the driving component 3 and the detection component 5 in the motor 10 shown in Figure 3A in some embodiments.

[0243] In some embodiments, the detection component 5 may be extended along the movement direction of the moving platform 2 relative to the fixed base 1 , and the detection component 5 is used to detect the position of the fixed base 1 on the moving platform 2 .

[0244] In this embodiment, the detection component 5 is extended along the movement direction of the moving platform 2 relative to the fixed base 1, so that the detection component 5 can realize position detection of the moving platform 2 throughout the entire movement path of the moving platform 2, which is beneficial to improving the position detection accuracy of the moving platform 2, thereby improving the accuracy of aligning the pin shaft 41 with the pin hole 11.

[0245] Exemplarily, the detection component 5 may include a tunneling magnetoresistance (TMR) 51 and a magnetic grating 52, the tunneling magnetoresistance 51 is installed on the moving platform 2, the magnetic grating 52 is installed on the fixed base 1, the magnetic grating 52 is extended along the movement direction of the moving platform 2 relative to the fixed base 1, and the tunneling magnetoresistance 51 and the magnetic grating 52 are arranged opposite to each other.

[0246] In this embodiment, the tunnel magnetic resistor 51 can move with the moving platform 2. Within the entire range of movement of the tunnel magnetic resistor 51, there is a part of the magnetic grid 52 that is arranged opposite to the tunnel magnetic resistor 51, so that the position of the tunnel magnetic resistor 51 can be obtained through the part where the magnetic grid 52 and the tunnel magnetic resistor 51 are opposite, and then the position of the moving platform 2 relative to the fixed base 1 can be determined to achieve position detection and alignment of the pin shaft 41 and the pin hole 11.

[0247] In which, along the moving direction of the moving platform 2 relative to the fixed base 1, the self-locking component 4 can be spaced apart from the magnetic grid 52.

[0248] In this embodiment, along the movement direction of the moving platform 2 relative to the fixed base 1, the self-locking component 4 is spaced apart from the magnetic grid 52, which can reduce the magnetic interference of the magnetic grid 52 on the magnetic drive component 42, thereby reducing the impact on the extension and retraction of the pin shaft 41, so as to reduce the interference with the locking effect of the moving platform 2 and the fixed base 1.

[0249] In which, along the stacking direction of the driving component 3 and the moving platform 2, the self-locking component 4 can be spaced apart from the magnetic grid 52.

[0250] In this embodiment, by spacing the self-locking component 4 and the magnetic grid 52 in multiple directions, the magnetic interference of the magnetic grid 52 on the magnetic drive component 42 can be reduced or even avoided, thereby reducing the impact on the extension and retraction of the pin shaft 41, thereby reducing the interference with the locking effect of the moving platform 2 and the fixed base 1.

[0251] The magnetic grid 52 may be at least partially embedded in the fixed base 1 .

[0252] In this embodiment, the second portion 1b of the fixed base 1 may be provided with a receiving groove 15 (see FIG. 4B ), with the opening of the receiving groove 15 facing the moving stage 2. By installing at least a portion of the magnetic grid 52 within the receiving groove 15, the magnetic grid 52 is embedded in the fixed base 1, thereby improving the installation stability of the magnetic grid 52. Moreover, by accommodating at least a portion of the magnetic grid 52 in the receiving groove 15, the exposure of the magnetic grid 52 from the fixed base 1 can be reduced or even avoided, thereby reducing the interference of the magnetic grid 52 with the movement of the moving stage 2 relative to the fixed base 1. In addition, embedding the magnetic grid 52 in the fixed base 1 can also save space and improve the space utilization of the motor 10.

[0253] In some other embodiments, the detection component 5 may also be a Hall detector to detect the position of the moving stage 2 .

[0254] Please refer to Figures 2A, 2B and 12B in combination. In some embodiments, the driving component 3 may include a driving coil 31 and a driving magnet 32, one of the driving coil 31 and the driving magnet 32 ​​is connected to the fixed base 1, and the other is connected to the moving platform 2.

[0255] In some examples, the driving coil 31 may be connected to the moving stage 2 , and the driving magnet 32 ​​may be connected to the fixed base 1 .

[0256] In this embodiment, the driving coil 31 is connected to the moving stage 2 , which can reduce the extra load of the moving stage 2 , and is conducive to the moving stage 2 being able to carry a heavier optical element 201 .

[0257] In the range of movement of the moving platform 2 relative to the fixed base 1 , part of the driving magnet 32 ​​is arranged opposite to the driving coil 31 .

[0258] In this embodiment, the driving magnet 32 ​​covers the entire range of movement of the driving coil 31, so that within the range of movement of the moving platform 2, the driving magnet 32 ​​can push the driving coil 31 to drive the moving platform 2 to move through the Lorentz force, which is beneficial to improving the stability of the driving component 3 driving the moving platform 2 to move.

[0259] In other examples, the driving magnet 32 ​​may be connected to the moving stage 2 , and the driving coil 31 may be connected to the fixed base 1 .

[0260] In this embodiment, the driving coil 31 is connected to the fixed base 1 so that the driving coil 31 does not need to move relative to the fixed base 1 , thereby avoiding the problem of harness connection movement caused by the movement of the driving coil 31 .

[0261] In some embodiments, the magnetic pole surface of the driving magnet 32 ​​may be arranged non-perpendicular to the movement direction of the pin 41 .

[0262] In this embodiment, by setting the magnetic pole surface of the driving magnet 32, the direction of the magnetic field of the driving magnet 32 ​​can be made to intersect with the movement direction of the pin shaft 41, so that the direction of the magnetic interference of the driving magnet 32 ​​on the magnet 422 in the magnetic drive component 42 intersects with the direction in which the magnet 422 drives the pin shaft 41 to move. The magnetic interference of the magnetic field of the driving magnet 32 ​​on the magnetic drive component 42 can be reduced, thereby reducing the influence on the extension and retraction of the pin shaft 41, so as to reduce the interference with the locking effect of the moving platform 2 and the fixed base 1.

[0263] It should be noted that the magnetic pole surface of the driving magnet 32 ​​can be a surface facing the self-locking component 4 and a surface facing away from the self-locking component 4. For example, the surface of the driving magnet 32 ​​facing the self-locking component 4 can be an N pole (not shown in the figure), and the surface of the driving magnet 32 ​​facing away from the self-locking component 4 can be an S pole (not shown in the figure). It is understood that the magnetic pole surface of the driving magnet 32 ​​can also be in other forms, for example, the S pole and N pole of the driving magnet 32 ​​can be interchangeable.

[0264] Among them, the magnetic pole surface of the driving magnet 32 ​​can be set parallel to the movement direction of the pin shaft 41 to further reduce the component size of the magnetic field of the driving magnet 32 ​​in the movement direction of the pin shaft 41, thereby further reducing the magnetic interference of the magnetic field of the driving magnet 32 ​​on the magnetic drive component 42, and further reducing the influence on the extension and retraction of the pin shaft 41, so as to further reduce the interference with the locking effect of the moving platform 2 and the fixed base 1.

[0265] Please refer to FIG. 2A , FIG. 12B and FIG. 13 . FIG. 13 is a schematic diagram of the installation of the self-locking component 4 , the driving component 3 , the detecting component 5 and the control circuit 6 in the motor 10 shown in FIG. 3A in some embodiments.

[0266] In some embodiments, the self-locking assembly 4 can be used to receive control instructions and drive the pin 41 to retract and disengage from the pin hole 11, thereby unlocking the moving stage 2 from the fixed base 1. Furthermore, the driving assembly 3 can be used to drive the moving stage 2 to move relative to the fixed base 1 after the pin 41 disengages from the pin hole 11, thereby switching the lens 20.

[0267] The detection assembly 5 is used to detect the position of the fixed base 1 during the movement of the moving platform 2 relative to the fixed base 1. This position information is used to assist in aligning the pin 41 with the pin hole 11. After the pin 41 is aligned with the pin hole 11, the self-locking assembly 4 is used to drive the pin 41 to extend and insert into the pin hole 11. The driving assembly 3 is used to stop driving the moving platform 2 after the pin 41 is inserted into the pin hole 11.

[0268] In this embodiment, through the cooperation of the self-locking component 4, the driving component 3 and the detection component 5, the orderly unlocking and locking of the moving platform 2 and the fixed base 1 can be achieved, so as to orderly realize the switching of the lens 20 of the camera module 100 in the electronic device 1000.

[0269] Illustratively, the control circuit 6 can receive control instructions from the processor in the electronic device 1000 to control the movement of the self-locking component 4 and the driving component 3, and the control circuit 6 can also receive the position information of the moving platform 2 detected by the detection component 5, and feed back the position information of the moving platform 2 to the processor to assist the processor in achieving logical control.

[0270] Specifically, the control logic of the motor 10 may include steps S10 , S20 , S30 , and S40 (not shown in the figure).

[0271] S10 , the detection component 5 detects the position information of the moving stage 2 .

[0272] The detection component 5 can confirm whether the pin 41 of the self-locking component 4 installed in the motion platform 2 is aligned with the pin hole 11 on the fixed base 1 by detecting the position information of the motion platform 2, and can also confirm which pin hole 11 the pin 41 is aligned with. The detection signal of the detection component 5 can be transmitted to the processor through the control circuit 6, so that the processor can process the detection signal of the detection component 5 to obtain the position information of the motion platform 2.

[0273] S20, the driving motor 10 drives the moving platform 2 to move relative to the fixed base 1, and the self-locking component 4 drives the pin shaft 41 to extend and insert into the pin hole 11 according to the position information of the moving platform 2 detected by the detection component 5, thereby completing the self-locking of the moving platform 2 and the fixed base 1.

[0274] Among them, when the moving platform 2 and the fixed base 1 are in an unlocked state, the driving motor 10 can drive the moving platform 2 to move relative to the fixed base 1 under the control of the control circuit 6, and when the pin shaft 41 is aligned with the pin hole 11, the control circuit 6 can transmit a control instruction to the self-locking component 4 to drive the pin shaft 41 to extend and insert into the pin hole 11.

[0275] Among them, when the pin shaft 41 is aligned with the pin hole 11, the control circuit 6 can control the pin shaft 41 to continue to be aligned with the pin hole 11 until the self-locking component 4 drives the pin shaft 41 to extend and insert into the pin hole 11, which can improve the accuracy of the pin shaft 41 inserted into the pin hole 11.

[0276] S30 , the self-locking component 4 drives the pin 41 to retract according to the control instruction of the switching lens 20 , thereby unlocking the moving stage 2 and the fixed base 1 .

[0277] The control circuit 6 can receive a control instruction for switching the lens 20 and transmit it to the self-locking component 4 so that the magnetic drive component 42 is reversely energized and the drive pin 41 is retracted to complete unlocking.

[0278] S40 , repeating steps S10 , S20 and S30 , and the moving platform 2 and the fixed base 1 perform the self-locking / unlocking action again at other positions.

[0279] The electronic device 1000 can be locked at different lenses 20 and switched between lenses 20 with different focal lengths through the above steps S10 , S20 and S30 .

[0280] Please refer to Figure 2B in conjunction with Figure 14. Figure 14 is a schematic diagram illustrating the structural layout of motor 10 in electronic device 1000 shown in Figure 2A in alternative embodiments. It should be noted that Figure 14 includes most of the technical features of motor 10 shown in Figures 2B and 3A. Only the differences between the two are described here, and the common features are not repeated.

[0281] In some embodiments, the drive assembly 3 can be disposed on both sides of the motion platform 2, the pin hole 11 can be disposed on the bottom side of the motion platform 2, and the self-locking assembly 4 can be disposed corresponding to the pin hole 11. In other words, the pin hole 11 can be disposed on the bottom wall 14 of the fixed base 1, and the pin shaft 41 of the self-locking assembly 4 extends toward the bottom wall 14 of the fixed base 1.

[0282] In this embodiment, the staggered arrangement of the drive assembly 3 and the self-locking assembly 4 helps reduce or even avoid structural interference between the self-locking assembly 4 and the drive assembly 3, and also reduces signal crosstalk between the drive assembly 3 and the self-locking assembly 4. In addition, since two sets of drive assemblies 3 can be provided on either side of the motion stage 2, this helps improve the balance of the motion stage 2 relative to the fixed base 1 and increases the power driving the motion stage 2.

[0283] It should be noted that the self-locking component 4 in the motor 10 shown in the embodiment of Figure 14 may include at least some of the technical features of the self-locking component 4 in the aforementioned embodiment, the driving component 3 in the motor 10 shown in the embodiment of Figure 14 may include at least some of the technical features of the driving component 3 in the aforementioned embodiment, the detection component 5 in the motor 10 shown in the embodiment of Figure 14 may include at least some of the technical features of the detection component 5 in the aforementioned embodiment, the moving platform 2 in the motor 10 shown in the embodiment of Figure 14 may include at least some of the technical features of the moving platform 2 in the aforementioned embodiment, and the fixed base 1 in the motor 10 shown in the embodiment of Figure 14 may include at least some of the technical features of the fixed base 1 in the aforementioned embodiment.

[0284] Please refer to Figure 15, which is a schematic diagram of the structure of the self-locking assembly 4 shown in Figure 7A, taken along line BB, in other embodiments. The self-locking assembly 4 shown in the embodiment of Figure 15 can include most of the technical features of the self-locking assembly 4 shown in the embodiment of Figure 7C. Only the differences between the two are described here, and the common parts are not repeated.

[0285] In some embodiments, the magnetic pole surface of the magnet 422 can be perpendicular to the axis of the pin 41. The coil 421 can be spaced apart and positioned on one side of the magnetic pole surface of the magnet 422, with the winding plane of the coil 421 parallel to the magnetic pole surface of the magnet 422. The coil 421 is configured to generate a Lorentz force under the action of the magnet 422 when energized. Within the range of movement of the pin 41 for extension and retraction, the magnet 422 and the coil 421 are at least partially positioned opposite each other.

[0286] In this embodiment, after the coil 421 is energized, it can generate a Lorentz force under the action of the magnetic field of the magnet 422. Since the coil 421 is fixed to the mounting base 44, the magnet 422 is pushed and extended, or pulled and retracted under the reaction force of the Lorentz force, thereby realizing the extension and retraction of the pin shaft 41.

[0287] It should be noted that the magnetic pole surfaces of the magnet 422 may be the N pole and the S pole as shown in FIG. 15 . It is understandable that in other embodiments, the N pole and the S pole of the magnet 422 may be interchangeable.

[0288] The coil 421 may be a runway-type coil. When the coil 421 is energized, the magnetic field of the magnet 422 generates a Lorentz force, which pushes the magnet 422 to drive the pin 41 to extend and retract.

[0289] Please refer to Figure 16, which is a schematic diagram of the structure of the self-locking assembly 4 shown in Figure 7A, taken along line BB, in further embodiments. The self-locking assembly 4 shown in the embodiment of Figure 16 can include most of the technical features of the self-locking assembly 4 shown in the embodiment of Figure 7C. Only the differences between the two are described here, and the common parts are not repeated.

[0290] In some embodiments, the magnetic pole surface of the magnet 422 is perpendicular to the axis of the pin 41, and the coil 421 is spaced apart on one side of the magnetic pole surface of the magnet 422. The coil 421 is configured to generate a magnetic force along the axis of the pin 41 when energized. The magnet 422 and the coil 421 form a counter-attraction structure, which can attract and repel the magnet 422 by changing the direction of the magnetic field of the coil 421, thereby driving the pin 41 to extend and retract.

[0291] In this embodiment, the coil 421 can generate a magnetic field on the winding surface facing the magnet 422 after being energized. Depending on the direction of the energized current, the coil 421 can interact with the magnet 422 to generate a magnetic repulsive force to push the magnet 422, or generate a magnetic attractive force to pull the magnet 422, thereby realizing the extension and retraction of the pin shaft 41.

[0292] It should be noted that the magnetic pole surfaces of the magnet 422 may be the N pole and the S pole as shown in FIG. 16 . It is understandable that in other embodiments, the N pole and the S pole of the magnet 422 may be interchangeable.

[0293] It should be noted that the self-locking component 4 provided in the embodiment of the present application can be completely decoupled from other parts in the camera module 100, and the self-locking component 4 can be effectively transplanted into other usage scenarios that require self-locking.

That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.
