Description

Technical Field

[0001] This invention relates to the field of camera technology, and more particularly to a camera module and electronic device. Background Technology

[0002] Mobile phones, cameras, computers, and other electronic devices typically have camera modules so users can take photos anytime, anywhere. During shooting, the camera module may shake due to external vibrations, affecting image quality.

[0003] Many image stabilization technologies have emerged in the market, such as micro-gimbal stabilization. Current micro-gimbals feature a hinge that connects to other structural components of the camera module. The camera module rotates around this hinge to achieve image stabilization. However, current micro-gimbals suffer from issues such as insufficiently smooth rotation and severe wear, resulting in a relatively high failure rate. Therefore, it is necessary to provide a camera module with a micro-gimbal that ensures smooth rotation, avoids wear issues, and improves the reliability and lifespan of the camera module's micro-gimbal. Summary of the Invention

[0004] This application provides a camera module and electronic device. The micro-gimbal in this application can drive the camera body to rotate along the axis, ensuring smooth rotation, avoiding wear and tear, and achieving image stabilization.

[0005] In a first aspect, embodiments of this application provide a camera module, which includes a housing, a camera body, and a micro-gimbal. The camera body is located inside the housing and includes a lens and a photosensitive element. The micro-gimbal includes a driving component, an adapter, two first springs, and two second springs. The two first springs are respectively arranged along a first direction on both sides of the camera body. One end of each first spring is fixedly connected to the camera body, and the other end is fixedly connected to the adapter. The two second springs are respectively arranged along a second direction on both sides of the camera body. The second direction intersects the first direction. One end of the second spring is fixedly connected to the adapter, and the other end of the second spring is fixedly connected to the housing. The driving member is used to drive the camera body to rotate around a first axis, which is parallel to the first direction. When the camera body rotates around the first axis, the first spring deforms. Alternatively, the driving member is also used to drive the camera body, the adapter, and the first spring to rotate around a second axis, which is parallel to the second direction. When the camera body rotates around the second axis, the second spring deforms. The photosensitive element is located on the image side of the lens. The lens may include lenses, and the number of lenses in the lens may be one, two, or three, etc. Multiple lenses are arranged sequentially in the optical axis direction, and light passes through each lens sequentially to form an image on the photosensitive element. The second direction may be perpendicular to the first direction.

[0006] In this embodiment, the driving component drives the lens and photosensitive element of the camera module to rotate together to achieve image stabilization. The positions of the lens and photosensitive element are relatively fixed in the non-focusing / non-optical axis direction, so that the image quality and image stabilization effect will not decrease at the edge of the image. This avoids the problem of mismatch between the lens and the principal angle of the photosensitive element when only the lens or only the photosensitive element is moved for image stabilization.

[0007] In this embodiment, one end of the first spring is fixedly connected to the camera body, and the other end of the first spring is fixedly connected to the adapter. One end of the second spring is fixedly connected to the adapter, and the other end of the second spring is fixedly connected to the housing. By setting the adapter, the second spring is connected to the camera body through the adapter and the first spring. In this way, the rotation of the camera body along the first axis will not affect the rotation of the camera body along the second axis (without the adapter, both first springs and both second springs are fixed to the camera body. When the camera body rotates along the first axis, it will affect the rotation along the second axis. The rotation in the two directions will interfere with each other, affecting the image stabilization effect). The adapter helps to avoid interference when the camera body rotates in multiple directions at the same time.

[0008] In this embodiment, the two first springs deform (e.g., torsional deformation) to form a first axis, and the two second springs deform to form a second axis. Both the first and second axes are virtual axes. When the camera body rotates around the first or second axis, there is no relative rotation between structural components, which avoids the unsmooth rotation caused by the use of solid rotating shafts in current micro-gimbals, as well as the wear problem of solid rotating shafts. In this embodiment, the processing precision requirements for the first springs used to form the first axis and the second springs used to form the second axis are low, resulting in high manufacturing yield and low cost.

[0009] In one possible implementation, the first reed includes a first movable part, a second movable part, and a first connecting part. One end of the first movable part is fixed to the first connecting part, and the other end of the first movable part is fixedly connected to the camera body. One end of the second movable part is fixed to the first connecting part, and the other end of the second movable part is fixedly connected to the camera body. The first connecting part is fixed to the adapter, and the first axis passes through the first connecting part. Both the first and second movable parts are fixedly connected to the first connecting part, forming a first axis at the first connecting part. The camera body rotates around the first axis without relative friction between structural components, avoiding the uneven rotation caused by the solid rotating shaft used in current micro-gimbals and the wear problem of solid rotating shafts. In this embodiment, the processing precision requirements for the first movable part, the second movable part, and the first connecting part used to form the first axis are low, resulting in high manufacturing yield and low cost.

[0010] In one possible implementation, the first reed includes a third movable part, which forms an "I" shaped structure, a "Y" shaped structure, or a "T" shaped structure with the first movable part and the second movable part.

[0011] In one possible implementation, the first movable part and the second movable part are symmetrical structures, and the first movable part and the second movable part have a balanced effect on the camera body, which is beneficial to the stable rotation and image stabilization of the camera body.

[0012] In one possible implementation, the first reed further includes a first suspension member, one end of which is fixedly connected to the first movable part, and the other end of which is fixedly connected to the second movable part. The first suspension member is fixed to the camera body. In this embodiment, the micro-gimbal is used to suspend the camera body. Since the camera body is relatively heavy, the first suspension member increases the connection area between the micro-gimbal and the camera body, thus preventing the connection point from easily breaking.

[0013] In one possible implementation, the first reed further includes a first stator and a second stator. The third movable portion includes a first sub-part and a second sub-part. One end of the first sub-part is fixedly connected to the first connecting portion, and the other end of the first sub-part is fixedly connected to the first stator. The first stator is fixedly connected to the adapter. One end of the second sub-part is fixedly connected to the first connecting portion, and the other end of the second sub-part is fixedly connected to the second stator. The second stator is fixedly connected to the adapter. The first sub-part, the second sub-part, the first movable portion, and the second movable portion can form a structure centered on the first connecting portion, i.e., an "I"-shaped structure, which facilitates the formation of the first axis. The first sub-part and the first movable portion can extend in the same direction, and the second sub-part and the second movable portion can extend in the same direction.

[0014] In other embodiments, the third movable part may also include a sub-part, the first reed includes a stator, one end of the sub-part is connected to the first connecting part, and the other end of the sub-part is connected to the stator. The sub-part, the first movable part, and the second movable part form a structure that extends in three different directions with the first connecting part as the center, namely a "Y"-shaped structure or a "T"-shaped structure.

[0015] In one possible implementation, the second reed includes a fourth movable part, a fifth movable part, and a second connecting part. One end of the fourth movable part is fixed to the second connecting part, and the other end of the fourth movable part is fixed to the adapter. One end of the fifth movable part is fixed to the second connecting part, and the other end of the fifth movable part is fixed to the adapter. The second connecting part is fixed to the housing, and the second axis passes through the second connecting part. Both the fourth and fifth movable parts are fixedly connected to the second connecting part, forming a second axis at the second connecting part. The camera body rotates around the second axis without relative friction between structural components, avoiding the uneven rotation caused by the solid rotating shaft in current micro-gimbals and the wear problem of solid rotating shafts. In this embodiment, the processing precision requirements for the fourth movable part, fifth movable part, and second connecting part used to form the second axis are low, resulting in high manufacturing yield and low cost.

[0016] In one possible implementation, the second reed includes a sixth movable part, which forms an "I" shaped structure, a "Y" shaped structure, or a "T" shaped structure with the fourth movable part and the fifth movable part.

[0017] In one possible implementation, the fourth and fifth movable parts are symmetrical in structure, and their effects on the camera body are balanced, which is beneficial for the stable rotation and image stabilization of the camera body.

[0018] In one possible implementation, the second spring further includes a second suspension member, one end of which is fixedly connected to the fourth movable part, and the other end of which is fixedly connected to the fifth movable part. The second suspension member is fixed to the adapter. In this embodiment, the micro-gimbal is used to suspend the camera body. Since the camera body is relatively heavy, the second suspension member increases the connection area between the micro-gimbal and the camera body, thus preventing the connection point from easily breaking.

[0019] In one possible implementation, the second reed further includes a third stator and a fourth stator. The sixth movable part includes a third sub-part and a fourth sub-part. One end of the third sub-part is fixedly connected to the second connecting part, and the other end of the third sub-part is fixedly connected to the third stator. The third stator is fixedly connected to the housing. One end of the fourth sub-part is fixedly connected to the second connecting part, and the other end of the fourth sub-part is fixedly connected to the fourth stator. The fourth stator is fixedly connected to the housing. The third sub-part, the fourth sub-part, the fourth movable part, and the fifth movable part can form a structure centered on the second connecting part, i.e., an "I"-shaped structure, which is beneficial for forming the second axis. The extension directions of the third sub-part and the fourth movable part can be the same, and the extension directions of the fourth sub-part and the fifth movable part can be the same.

[0020] In other embodiments, the sixth movable part may also include a sub-part, the second reed includes a stator, one end of the sub-part is connected to the second connecting part, and the other end of the sub-part is connected to the stator. The sub-part, the fourth movable part, and the fifth movable part form a structure that extends in three different directions with the second connecting part as the center, namely a "Y"-shaped structure or a "T"-shaped structure.

[0021] In one possible implementation, the first spring is a one-piece molded structure, or the second spring is a one-piece molded structure, which makes the first and second springs have high structural strength, which is beneficial to improving the reliability of the micro-gimbal suspension housing and the camera body, and preventing the micro-gimbal from losing its image stabilization function due to breakage of the first and second springs.

[0022] In one possible implementation, the adapter includes a first adapter portion and a second adapter portion spaced apart, a first spring connecting the first adapter portion and the second adapter portion, one second spring fixed to the first adapter portion, and the other second spring fixed to the second adapter portion. The first spring connecting the first adapter portion and the second adapter portion helps to reduce the manufacturing cost of the adapter.

[0023] In one possible implementation, the micro-gimbal includes a damping element located between the first spring and the camera body, or between the second spring and the adapter, or between the adapter and the camera body. The number of damping elements can be one, two, or three, etc., and this application does not limit this. Providing a damping element between the first spring and the camera body, or between the second spring and the adapter, or between the adapter and the camera body, can constrain the rotation of the camera body, requiring it to overcome a certain damping force and rotate smoothly, preventing arbitrary rotation. The damping element can be a damping adhesive, etc.

[0024] In one possible implementation, the number of damping elements is at least two, and the at least two damping elements are symmetrically distributed around the center of the camera body. Having at least two damping elements provides sufficient damping force. The symmetrical distribution of at least two damping elements around the center of the camera body helps to provide a uniform damping force to the system, improving the system's balance.

[0025] In one possible implementation, the driving component includes a magnetic component fixed to the housing. The magnetic component provides a magnetic field, and the camera body includes a coil. When energized, the coil can move under the magnetic field and drive the camera body to rotate. Alternatively, the driving component includes a coil fixed to the housing, and the camera body includes a magnetic component providing a magnetic field. When energized, the coil can move under the magnetic field and drive the camera body to rotate. In this embodiment, a driving method involving interaction between a magnetic component and a coil can be used, resulting in low power consumption. The camera body may contain a coil or a magnetic component. When a coil is present within the camera body, the driving component can be set as a magnetic component, interacting with the coil within the camera body, reducing the number of coils. When a magnetic component is present within the camera body, the driving component can be set as a coil, interacting with the magnetic component within the camera body, reducing the number of magnetic components. This facilitates miniaturization of the micro-gimbal and the overall structure of the camera module, and saves costs.

[0026] In one possible implementation, the driving element includes a magnetic element fixed to the housing, with the first axis passing through the center of the magnetic element. The first axis passing through the center of the magnetic element helps to avoid friction between the coil and the magnetic element during coil movement, thus preventing motion interference between the coil and the magnetic element.

[0027] In one possible implementation, the driving element includes a coil, or the camera body includes a coil. The magnetic element includes a first magnetic part and a second magnetic part. The first magnetic part includes a first end and a second end disposed opposite to each other, and the second magnetic part includes a third end and a fourth end disposed opposite to each other. Along the optical axis of the lens, the first end, the second end, the third end, and the fourth end are arranged sequentially. The distance between the first end and the coil is greater than the distance between the second end and the coil, and the distance between the third end and the coil is less than the distance between the fourth end and the coil. A first axis passes through the center of the magnetic element, making it easier for the first end and the fourth end to interfere with the coil. Understandably, the greater distance between the first end and the coil than the greater distance between the second end and the coil allows the surface of the first magnetic part facing the coil to be inclined, and the greater distance between the first end and the coil than the greater distance between the second end and the coil helps to avoid motion interference between the first end and the coil as the camera body rotates. The distance between the third end and the coil is less than the distance between the fourth end and the coil, which allows the surface of the second magnetic part facing the coil to be inclined. The distance between the fourth end and the coil is greater than the distance between the third end and the coil, which helps to avoid motion interference between the fourth end and the coil as the coil rotates with the camera body.

[0028] In one possible implementation, the magnetic component includes a first magnetic part and a second magnetic part, which are spaced apart along the optical axis of the lens. At least a portion of the first reed or at least a portion of the second reed is located between the first magnetic part and the second magnetic part. The fact that at least a portion of the first reed is located between the first magnetic part and the second magnetic part, and at least a portion of the second reed is located between the first magnetic part and the second magnetic part, allows for partial overlap between the first reed, the second reed, and the magnetic component in the direction perpendicular to the optical axis. This helps reduce the size of the micro-gimbal in the direction perpendicular to the optical axis, achieving miniaturization of the micro-gimbal, reducing its space occupation within the electronic device, and improving the space utilization of the electronic device.

[0029] Secondly, this application provides an electronic device, including an image processor and a camera module as described in any of the foregoing embodiments. The image processor is communicatively connected to the camera module, and is used to acquire image data from the camera module and process the image data. The electronic device can be a mobile phone, camera, computer, etc. Attached Figure Description

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] like Figure 1 As shown, Figure 1This is a structural schematic diagram of an electronic device 100. This application provides an electronic device 100, which can be a mobile phone, camera, tablet computer, laptop, wearable device, or other device with photographic or video recording functions. This application describes the electronic device 100 as a mobile phone as an example.

[0051] The electronic device 100 may include a housing 10, a camera module 20, and an image processor 30. The camera module 20 and the image processor 30 are located within the housing 10, and the camera module 20 and the image processor 30 are communicatively connected. The camera module 20 is used to acquire image data and input the image data to the image processor 30, which is used to process the image data acquired from the camera module 20. The communication connection between the camera module 20 and the image processor 30 may include data transmission via electrical connections such as wiring, or data transmission via coupling or other methods. It is understood that the camera module 20 and the image processor 30 may also be connected via other methods capable of data transmission.

[0052] The image processor 30 performs a series of complex mathematical algorithms to optimize digital image signals and then transmits the processed signals to the display for showing. The image processor 30 can be an image processing chip or a digital signal processing chip, capable of processing both image and digital signals. Its function is to transmit the data obtained by the image sensor of the camera module 20 to the central processing unit in a timely and rapid manner and to refresh the image sensor. Therefore, the quality and stability of the chip directly affect the image quality (such as color saturation and sharpness).

[0053] In one specific embodiment, the camera module 20 can be disposed on the back of the electronic device 100, serving as a rear camera. In other embodiments, the camera module 20 can also be disposed on the front of the electronic device 100, serving as a front camera. Both the front and rear cameras can be used for selfies or for the photographer to capture images of other objects.

[0054] Understandable Figure 1 The installation position of the camera module 20 in the illustrated embodiment of the electronic device 100 is merely illustrative, and this application does not strictly limit the installation position of the camera module 20. In some other embodiments, the camera module 20 may also be installed in other positions of the electronic device 100, such as the upper middle or upper right corner of the electronic device 100. Alternatively, the camera module 20 may not be mounted on the main body of the phone, but on an auxiliary component that is movable or rotatable relative to the phone, such as an auxiliary component that can extend, retract, or rotate from the main body of the phone.

[0055] In some embodiments, the electronic device 100 may further include an analog-to-digital converter (also known as an A / D converter). Figure 1 (Not shown). An analog-to-digital converter is connected between the camera module 20 and the image processor 30. The analog-to-digital converter is used to convert the signal generated by the camera module 20 into a digital image signal and transmit it to the image processor 30. The image processor 30 then processes the digital image signal and finally displays the image or video on the display.

[0056] In some embodiments, the electronic device 100 may further include a memory ( Figure 1 (Not shown) The memory is communicatively connected to the image processor 30. After processing the digital image signal, the image processor 30 transmits the image to the memory so that the image can be retrieved from the memory and displayed on the monitor at any time when it is needed to view the image later. In some embodiments, the image processor 30 also compresses the processed digital image signal before storing it in the memory to save memory space.

[0057] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, Figure 2 for Figure 1 The diagram shown illustrates the structure of the camera module 20. Figure 3 yes Figure 2 A partial structural diagram of the camera module 20 shown. Figure 3 This is to allow for a clearer view of the internal structure of the casing 210. Figure 2 The diagram shown is a structural schematic of the camera module 20 after removing the housing 210. Figure 4 for Figure 3 A top view of part of the structure of the camera module 20 shown. Figure 4 To see the structure of the first reed 51 more clearly, Figure 3 Top view after removing drive component 52. Figure 5 for Figure 3 The image shows a cross-sectional view of the camera module 20 at point AA. Figure 5 Shot 40 in the video is only illustrative. Figure 5 The lens of lens 40 is not shown.

[0058] The camera module 20 may include a housing 210, a camera body 220, and a micro-gimbal 50. The camera body 220 is located inside the housing 210. The micro-gimbal 50 connects the housing 210 and the camera body 220 and is used to drive the movement of the camera body 220 to achieve image stabilization. The camera body 220 may include a lens 40 and a photosensitive element 60. The lens 40 may include at least one lens; exemplarily, the number of lenses may be one, two, or three. The photosensitive element 60 is relatively fixed in position to the lens 40 and is located on the image side of the lens 40. Light entering the camera module 20 passes sequentially through the lens of the lens 40 and the photosensitive element 60, and an image is formed on the photosensitive element 60.

[0059] The micro-gimbal 50 may include two first springs 51, two second springs 53, an adapter 54, and a drive unit 52. The two first springs 51 are arranged along a first direction A1 on both sides of the camera body 220, with one end of each spring fixedly connected to the camera body 220 and the other end fixedly connected to the adapter 54. The two second springs 53 are arranged along a second direction A2 on both sides of the camera body 220, with one end of each spring fixedly connected to the adapter 54 and the other end fixedly connected to the housing 210. The second direction A2 intersects the first direction A1; exemplarily, the second direction A2 is perpendicular to the first direction A1.

[0060] See Figure 4 In some embodiments, the adapter 54 may include a first adapter portion 541 and a second adapter portion 542 spaced apart, a first spring 51 connecting the first adapter portion 541 and the second adapter portion 542, a second spring 53 fixed to the first adapter portion 541, and another second spring 53 fixed to the second adapter portion 542. The first spring 51 connecting the first adapter portion 541 and the second adapter portion 542 helps to save manufacturing costs for the adapter 54.

[0061] See Figure 2 and Figure 3 The driving component 52 may include a magnetic component 521 and a coil 522. The magnetic component 521 may be fixed to the inner wall of the housing 210, and the coil 522 may be fixed to the outer wall of the camera body 220. The magnetic component 521 and the coil 522 are correspondingly arranged. When current is passed through the coil 522, a magnetic field is generated, which interacts with the magnetic field of the magnetic component 521 to drive the camera body 220 to rotate. Multiple magnetic components 521 and coils 522 may be provided, and this application does not limit this.

[0062] In other embodiments, the driving element 52 may also be a shape memory alloy. This application does not limit the driving form of the driving element 52, as long as it can drive the camera body 220 to move.

[0063] The driving component 52 can be used to drive the camera body 220 to rotate around the first axis X, which is parallel to the first direction A1. When the camera body 220 rotates around the first axis X, the first spring 51 deforms, and the deformation can be in the form of torsional deformation or the like. The first axis X can be perpendicular to the optical axis O of the lens 40.

[0064] Alternatively, the driving component 52 can also be used to drive the camera body 220, the adapter 54, and the first spring 51 to rotate around the second axis Y. The second axis Y is parallel to the second direction A2. When the camera body 220 rotates around the second axis Y, the second spring 53 deforms, and the deformation can be in the form of torsional deformation or the like. The second axis Y can be perpendicular to the optical axis O of the lens 40.

[0065] Understandably, the driving element 52 can drive the camera body 220 to rotate around the first axis X, or the driving element 52 can drive the camera body 220 to rotate around the second axis Y, or the driving element 52 can drive the camera body 220 to rotate around the first axis X and around the second axis Y.

[0066] In this embodiment, the drive unit 52 can drive the lens 40 and the photosensitive element 60 to rotate together, achieving image stabilization. The lens 40 and the photosensitive element 60 are relatively fixed in the non-focusing / non-optical axis direction, so that the image quality and image stabilization effect will not degrade at the image edges. This avoids the problem of mismatch between the lens of the lens 40 and the principal angle of the photosensitive element 60 caused by only driving the lens 40 or only driving the photosensitive element 60 to move for image stabilization. The drive unit 52 drives the overall movement of the lens 40 and the photosensitive element 60 to achieve image stabilization without affecting the imaging quality of the camera module 20. One end of the first spring 51 is fixedly connected to the camera body 220, and the other end of the first spring 51 is fixedly connected to the adapter 54. One end of the second spring 53 is fixedly connected to the adapter 54, and the other end of the second spring 53 is fixedly connected to the housing 210. By setting the adapter 54, the second spring 53 is connected to the camera body 220 through the adapter 54 and the first spring 51. In this way, the rotation of the camera body 220 along the first axis X will not affect the rotation of the camera body 220 along the second axis Y (when the adapter 54 is not set, both first springs 51 and both second springs 53 are fixed to the camera body 220. When the camera body 220 rotates along the first axis X, it will affect the rotation along the second axis Y. The rotation in the two directions will interfere and affect the image stabilization effect). The setting of the adapter 54 helps to avoid interference when the camera body 220 rotates in multiple directions at the same time.

[0067] The arrangement of the two first springs 51 in this embodiment enables the micro-gimbal 50 to form a first axis X, and the arrangement of the two second springs 53 enables the micro-gimbal 50 to form a second axis Y. Both the first axis X and the second axis Y are virtual axes. When the camera body 220 rotates around the first axis X or the second axis Y, there is no relative rotation between structural components, which avoids the problem of uneven rotation caused by the use of solid rotating shafts in current micro-gimbals, as well as the wear problem of solid rotating shafts. In this embodiment, the processing accuracy requirements for the first springs 51 used to form the first axis X and the second springs 53 used to form the second axis Y are low, the manufacturing yield is high, and the cost is low.

[0068] See Figure 5 and Figure 6 , Figure 6 for Figure 3 The diagram shows an exploded view of the camera module 20. The camera body 220 may include a motor 61, and the lens of the lens 40 is located within the motor 61. The motor 61 may include a protective housing 611, a movable part 612, and a fixed part 613. The fixed part 613 is fixedly connected to the circuit board 62 (the camera body 220 may also include the circuit board 62). The movable part 612 and the fixed part 613 are movably connected. The movable part 612 may be located within the protective housing 611 and can move relative to the fixed part 613 to drive the lens of the lens 40 to move along the optical axis O, achieving focusing. The photosensitive element 60 may be fixed to the circuit board 62.

[0069] See Figure 4 and Figure 7 , Figure 7 for Figure 6 The diagram shows an exploded view of the micro-gimbal 50. The first spring 51 may include a first movable part 511, a second movable part 512, and a first connecting part 514. One end of the first movable part 511 is fixed to the first connecting part 514, and the other end of the first movable part 511 is used to fixally connect to the camera body 220. One end of the second movable part 512 is fixed to the first connecting part 514, and the other end of the second movable part 512 is used to fixally connect to the camera body 220. The first connecting part 514 can fix the adapter 54, and the first axis X passes through the first connecting part 514. Exemplarily, the first adapter 541 and the second adapter 542 are connected as one unit, and the first adapter 541 is fixed to the adapter 54.

[0070] In some embodiments, the first reed 51 may further include a third movable portion 513, which may form an "I" shape, a "Y" shape, or a "T" shape with the first movable portion 511 and the second movable portion 512. Understandably, the first connecting portion 514 may be fixed to the adapter 54 via the third movable portion 513.

[0071] For example, the first reed 51 may further include a first stator 515 and a second stator 516, and the third movable part 513 may include a first sub-part 517 and a second sub-part 518. The first sub-part 517 and the second sub-part 518 are located on opposite sides of the first axis X. One end of the first sub-part 517 is fixedly connected to the first connecting part 514, and the other end of the first sub-part 517 is fixedly connected to the first stator 515. The first stator 515 is fixedly connected to the adapter 54. One end of the second sub-part 518 is fixedly connected to the first connecting part 514, and the other end of the second sub-part 518 is fixedly connected to the second stator 516. The second stator 516 is fixedly connected to the adapter 54.

[0072] The first sub-part 517 is provided correspondingly to the first movable part 511. The extension directions of the first sub-part 517 and the first movable part 511 can be the same or different. The second sub-part 518 is provided correspondingly to the second movable part 512. The extension directions of the second sub-part 518 and the second movable part 512 can be the same or different. The first sub-part 517, the second sub-part 518, the first movable part 511 and the second movable part 512 are distributed around the first connecting part 514 to form an "I" shaped structure.

[0073] In other embodiments, the third movable part 513 may also include a sub-part, the first spring 51 includes a stator, one end of the sub-part is connected to the first connecting part 514, and the other end of the sub-part is connected to the stator. The sub-part, the first movable part 511 and the second movable part 512 form a structure that extends in three different directions with the first connecting part 514 as the center, that is, a "Y" shaped structure or a "T" shaped structure.

[0074] In some embodiments, the first movable part 511 and the second movable part 512 are symmetrically structured. The first sub-part 517 and the second sub-part 518 may also be symmetrically structured. The symmetrical structure of the first movable part 511 and the second movable part 512 ensures that the effects of the first movable part 511 and the second movable part 512 on the camera body are balanced, which can increase the structural stability of the first spring 51, facilitate the stable rotation and image stabilization of the camera body 220, and improve the image stabilization effect.

[0075] Understandably, the first movable part 511, the second movable part 512, and the third movable part 513 may have telescopic deformation characteristics, which is beneficial to provide a movement margin for the movement of the first movable part 511, the second movable part 512, and the third movable part 513, and to prevent the first movable part 511, the second movable part 512, and the third movable part 513 from being pulled during movement, thus affecting the rotational anti-shake of the camera module 20.

[0076] See Figure 3 and Figure 5In some embodiments, the first reed 51 and the driving member 52 are arranged sequentially at intervals along the optical axis O, and the first axis X does not pass through the driving member 52. Both the first reed 51 and the driving member 52 can be set close to the camera body 220, which is beneficial to reducing the size of the camera module 20 in the direction perpendicular to the optical axis O, and is beneficial to the miniaturization of the camera module 20.

[0077] See Figure 4 , Figure 7 and Figure 8 As shown, Figure 8 for Figure 3 The diagram shows a structural schematic of the camera module 20 from another angle. The second spring 53 may include a fourth movable part 531, a fifth movable part 532, and a second connecting part 534. One end of the fourth movable part 531 is fixed to the second connecting part 534, and the other end of the fourth movable part 531 is fixed to the adapter 54. One end of the fifth movable part 532 is fixed to the second connecting part 534, and the other end of the fifth movable part 532 is fixed to the adapter 54. The second connecting part 534 is fixed to the housing 210, and the second axis Y passes through the second connecting part 534.

[0078] In some embodiments, the second reed 53 further includes a sixth movable portion 533, which forms an "I" shaped structure, a "Y" shaped structure, or a "T" shaped structure with the fourth movable portion 531 and the fifth movable portion 532. Understandably, the second connecting portion 534 can be fixed to the housing 210 through the sixth movable portion 533.

[0079] For example, the second reed 53 may further include a third stator 535 and a fourth stator 536. The sixth movable part 533 includes a third sub-part 537 and a fourth sub-part 538, which are located on opposite sides of the second axis Y. One end of the third sub-part 537 is fixedly connected to the second connecting part 534, and the other end of the third sub-part 537 is fixedly connected to the third stator 535, which is fixedly connected to the housing 210. One end of the fourth sub-part 538 is fixedly connected to the second connecting part 534, and the other end of the fourth sub-part 538 is fixedly connected to the fourth stator 536, which is fixedly connected to the housing 210.

[0080] The third sub-part 537 is provided correspondingly to the fourth movable part 531. The extension directions of the third sub-part 537 and the fourth movable part 531 can be the same or different. The fourth sub-part 538 is provided correspondingly to the fifth movable part 532. The extension directions of the fourth sub-part 538 and the fifth movable part 532 can be the same or different. The third sub-part 537, the fourth sub-part 538, the fourth movable part 531 and the fifth movable part 532 are distributed around the second connecting part 534 to form an "I" shaped structure.

[0081] In other embodiments, the sixth movable part 533 may also include a sub-part, the second reed 53 includes a stator, one end of the sub-part is connected to the second connecting part 534, and the other end of the sub-part is connected to the stator. The sub-part, the fourth movable part 531 and the fifth movable part 532 form a structure centered on the second connecting part 534 and extending in three different directions, that is, forming a "Y" shaped structure or a "T" shaped structure.

[0082] In some embodiments, the fourth movable part 531 and the fifth movable part 532 are symmetrical. The third sub-part 537 and the fourth sub-part 538 can also be symmetrical. The symmetrical structure of the fourth movable part 531 and the fifth movable part 532 can increase the structural stability of the second spring 53, which is beneficial to the stable rotation and image stabilization of the camera body 220 and improves the image stabilization effect.

[0083] Understandably, the fourth movable part 531, the fifth movable part 532, and the sixth movable part 533 may have telescopic deformation characteristics, which is beneficial to provide a movement margin for the movement of the fourth movable part 531, the fifth movable part 532, and the sixth movable part 533, and to prevent the fourth movable part 531, the fifth movable part 532, and the sixth movable part 533 from being pulled during movement, thus affecting the rotational anti-shake of the camera module 20.

[0084] See Figure 7 The first spring 51 may further include a first suspension member 519, one end of which is fixedly connected to a first movable part 511, and the other end of which is fixedly connected to a second movable part 512. The first suspension member 519 is fixed to the camera body 220. Understandably, the first suspension member 519 may be fixed to the surface of the camera body 220 or embedded in the camera body 220. The second spring 53 may include a second suspension member 539, one end of which is fixedly connected to a fourth movable part 531, and the other end of which is fixedly connected to a fifth movable part 532. The second suspension member 539 is fixed to the adapter 54. Understandably, the second suspension member 539 may be fixed to the surface of the adapter 54 or embedded in the adapter 54.

[0085] In this embodiment, the micro-gimbal 50 is used to suspend the camera body 220. The camera body 220 is relatively heavy. By setting a first suspension member 519 or a second suspension member 539 (understandably, either the first suspension member 519 or the second suspension member 539 can be set, or both can be set), the connection area between the micro-gimbal 50 and the camera body 220 is increased, avoiding the problem that the connection between the micro-gimbal 50 and the camera body 220 is prone to breakage.

[0086] In some embodiments, the first spring 51 and the second spring 53 can be integrally molded, which makes the first spring 51 and the second spring 53 have high structural strength, prevents the first spring 51 and the second spring 53 from breaking, and helps to improve the reliability of the micro-gimbal 50 suspension housing 210 and the camera body 220.

[0087] like Figure 9 As shown, Figure 9 This is a schematic diagram of another camera module 20. The micro-gimbal 50 may also include a damping element 55, which may be a damping adhesive. The damping element 55 is used to provide sufficient damping force for the camera module 20. The damping element 55 may be located between the first spring 51 and the camera body 220. For example, the damping element 55 may be located between the first stator 515 and the camera body 220, or the damping element 55 may be located between the second stator 516 and the camera body 220. The damping element 55 may also be located between the second spring 53 and the adapter 54. For example, the damping element 55 may be located between the third stator 535 and the adapter 54, or the damping element 55 may be located between the fourth stator 536 and the adapter 54. The damping element 55 may also be located between the adapter 54 and the camera body 220. The number of damping elements 55 may be one, two, or three, etc., and this application does not limit this. When the number of damping elements 55 is at least two, at least two damping elements 55 are symmetrically distributed around the center of the camera body 220.

[0088] Damping elements 55 are provided between the first reed 51 and the camera body 220, between the second reed 53 and the adapter 54, or between the adapter 54 and the camera body 220. These damping elements constrain the rotation of the camera body 220, ensuring it overcomes a certain damping force and rotates smoothly, preventing arbitrary rotation. Having at least two damping elements 55 provides sufficient damping force. The symmetrical distribution of at least two damping elements 55 around the center of the camera body 220 helps provide a uniform damping force and improves system balance.

[0089] Understandably, Figure 9 The number and position of the damping elements 55 are only schematic representations, and this application does not limit the arrangement of the damping elements 55.

[0090] like Figure 6 and Figure 10A As shown, Figure 10A for Figure 3 The diagram shows a partial structural schematic of the camera module 20. The driving component 52 may include a magnetic component 521 (without a coil 522, i.e., without it). Figure 6The coil 522 and magnetic element 521 are fixed to the housing 210. The magnetic element 521 can be used to provide a magnetic field. The camera body 220 may include a coil 420, which can be fixed inside the motor 61. When energized, the coil 420 can move under the magnetic field and drive the camera body 220 to rotate around the first axis X or the second axis Y.

[0091] In other embodiments, see, for example Figure 6 and Figure 10B , Figure 10B This is a partial structural diagram of another camera module 20. The driving component 52 may include a coil 522 (without the magnetic component 521, i.e., the magnetic component 521 is removed). Figure 6 The magnetic component 521) and coil 522 can be fixed to the housing 210. The camera body 220 can include a magnetic component 430, which is used to provide a magnetic field. When energized, the coil 522 can move under the magnetic field and drive the camera body 220 to rotate around the first axis X or the second axis Y.

[0092] In this embodiment, a driving method involving the interaction of magnetic components and coils can be used, resulting in low power consumption. The camera module 20 may contain coils or magnetic components within its camera body 220. When a coil is present within the camera body 220, the driving component 52 can be configured as a magnetic component, interacting with the coil within the camera body 220, thus reducing the number of coils. Similarly, when a magnetic component is present within the camera body 220, the driving component 52 can be configured as a coil, interacting with the magnetic component within the camera body 220, further reducing the number of magnetic components. This facilitates the miniaturization of the micro-gimbal 50 and the overall structure of the camera module 20, while also saving costs.

[0093] like Figure 11 As shown, Figure 11 for Figure 3 The simulation effect diagram of the camera module 20 shown. Figure 11 In diagram (a1), the camera module 20 rotates around the second axis Y for image stabilization, with the resonant frequency of the image stabilization motor being 70Hz. In diagram (a2), the camera module 20 rotates around the first axis X for image stabilization, with the resonant frequency of the image stabilization motor being 82Hz. Based on the bandwidth requirements of the image stabilization algorithm for the camera module 20 and the requirement for system consistency under various gravity attitudes, image stabilization with a resonant frequency between 60Hz and 90Hz provides better image stabilization performance. The image stabilization micro-gimbal involved in this invention meets this requirement.

[0094] like Figure 12 and Figure 13 As shown, Figure 12 This is a schematic diagram of another type of camera module 20. Figure 13 yes Figure 12 The diagram shows the structure of the micro-gimbal 50. Figure 12 and Figure 13The camera module 20 shown is Figure 3 The difference in the camera module 20 shown is that, Figure 3 The first spring 51 of the camera module 20 shown is located below the drive member 52, and the first axis X does not pass through the drive member 52. Figure 12 and Figure 13 The first axis X shown passes through the center of the magnetic element 521 of the drive element 52, which helps to avoid the coil 522 from contacting the magnetic element 521 and causing friction when it moves with the camera body 220, prevents motion interference between the coil 522 and the magnetic element 521, helps to reduce the distance between the magnetic element 521 and the coil 522, and provides sufficient driving force to achieve a larger anti-shake angle.

[0095] Understandably, Figure 12 and Figure 13 A driving element 52 is also provided on the side where the first reed 51 is located. The positional relationship between the first reed 51 and the driving element 52 can be referred to the positional relationship between the second reed 53 and the driving element 52.

[0096] The magnetic component 521 may include a first magnetic part 5211 and a second magnetic part 5212. The first magnetic part 5211 and the second magnetic part 5212 may be in contact or spaced apart in the optical axis direction O. This embodiment of the application takes the first magnetic part 5211 and the second magnetic part 5212 being spaced apart in the optical axis O as an example. At least a portion of the first spring 51 or at least a portion of the second spring 53 is located between the first magnetic part 5211 and the second magnetic part 5212. In the direction perpendicular to the optical axis O, the first spring 51 or the second spring 53 can partially overlap with the magnetic component 521. This helps to reduce the size of the micro-gimbal 50 in the direction perpendicular to the optical axis, achieving miniaturization of the micro-gimbal 50, reducing the space occupied by the micro-gimbal 50 within the electronic device 100, and improving the space utilization rate of the electronic device 100.

[0097] like Figure 14 As shown, Figure 14 yes Figure 12 The image shows a cross-sectional view of the camera module 20 at point BB. Figure 14 Shot 40 in the video is only illustrative. Figure 14 The lens of lens 40 is not shown. The first magnetic part 5211 includes a first end 5213 and a second end 5214 disposed opposite to each other. The second magnetic part 5212 includes a third end 5215 and a fourth end 5216 disposed opposite to each other. In the optical axis direction O, the first end 5213, the second end 5214, the third end 5215 and the fourth end 5216 are arranged sequentially. The distance between the first end 5213 and the coil 522 is greater than the distance between the second end 5214 and the coil 522, and the distance between the third end 5215 and the coil 522 is less than the distance between the fourth end 5216 and the coil 522.

[0098] The first axis X is located between the first magnetic part 5211 and the second magnetic part 5212. This can be understood as the first axis X passing through the center of the magnetic component 521, making it easier for the first end 5213 and the fourth end 5216, which are away from the first axis X, to interfere with the coil 522. Alternatively, the second axis Y is located between the first magnetic part 5211 and the second magnetic part 5212. This can also be understood as the second axis Y passing through the center of the magnetic component 521, making it easier for the first end 5213 and the fourth end 5216, which are away from the second axis Y, to interfere with the coil 522. Understandably, the distance between the first end 5213 and the coil 522 is greater than the distance between the second end 5214 and the coil 522. This allows the surface of the first magnetic part 5211 facing the coil 522 to be inclined, and the distance between the first end 5213 and the coil 522 to be greater than the distance between the second end 5214 and the coil 522. This helps to avoid motion interference between the first end 5213 and the coil 522 during the rotation of the coil 522 with the lens 40. The distance between the third end 5215 and the coil 522 is smaller than the distance between the fourth end 5216 and the coil 522, which allows the surface of the second magnetic part 5212 facing the coil 522 to be inclined. The distance between the fourth end 5216 and the coil 522 is greater than the distance between the third end 5215 and the coil 522, which helps to avoid motion interference between the fourth end 5216 and the coil 522 during the rotation of the coil 522 with the lens 40.

[0099] In this embodiment, a coil 522 is provided outside the camera body 220 as an example. In other embodiments, the magnetic component may also interact with the coil 420 inside the camera body 220.

[0100] like Figure 15 As shown, Figure 15 This is a schematic diagram of the structure of a driving component 52. The first magnetic part 5211 and the second magnetic part 5212 of the magnetic component 521 can contact each other. The distance between the first end 5213 and the coil 522 is greater than the distance between the second end 5214 and the coil 522. The distance between the third end 5215 and the coil 522 is less than the distance between the fourth end 5216 and the coil 522.

[0101] like Figure 16 As shown, Figure 16 This is a schematic diagram of another type of driving component 52. The first magnetic part 5211 and the second magnetic part 5212 of the magnetic component 521 are in partial contact. The distance between the first end 5213 and the coil 522 is greater than the distance between the second end 5214 and the coil 522. The distance between the third end 5215 and the coil 522 is less than the distance between the fourth end 5216 and the coil 522.

[0102] like Figure 17 As shown, Figure 17 for Figure 12 The simulation effect diagram of the camera module 20 shown. Figure 17In diagram (b1), the camera module 20 rotates around the second axis Y for image stabilization, with the resonant frequency of the image stabilization motor being 72.6 Hz. In diagram (b2), the camera module 20 rotates around the first axis X for image stabilization, with the resonant frequency of the image stabilization motor being 87 Hz. Based on the bandwidth requirements of the image stabilization algorithm for the camera module 20 and the requirement for system consistency under various gravity attitudes, image stabilization with a resonant frequency between 60 Hz and 90 Hz provides better image stabilization performance. The image stabilization micro-gimbal involved in this invention meets this requirement.

[0103] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
