Description
Technical Field
[0001] This application belongs to the field of camera technology, and in particular relates to a gimbal module and electronic device. Background Technology
[0002] With the increasing imaging capabilities of mobile terminals, smart wearable devices, and other portable electronic devices, camera modules, in addition to autofocus and imaging, also need to compensate for image shifts caused by hand tremors, device vibrations, or impacts. Gimbal modules can change the camera module's posture by rotating it in different directions and work in conjunction with the control system to achieve image stabilization compensation.
[0003] In related technologies, gimbals typically employ two sets of drive structures, each driving the camera module to move in two mutually perpendicular directions. When both sets of drive structures are concentrated on the same support structure, when one drive structure moves in one direction, it causes relative displacement between the two drive components of the other drive structure. Consequently, the magnetic field coordination between the two drive components of the other drive structure changes, resulting in electromagnetic crosstalk between them.
[0004] In this situation, the control system needs to compensate for this mutual influence, which increases the complexity of the anti-shake control. Summary of the Invention

[0026] The embodiments of this application are described in detail below. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. The accompanying drawings are only used to illustrate the relative relationships between the various structures, and the shape, size, and proportion of each structure can be adjusted according to the installation space and driving requirements of the actual product.
[0027] like Figures 1-15 As shown, this application provides a gimbal module, which includes a camera module 100, an adapter frame 200, and a fixed outer frame 300.
[0028] The camera module 100 includes a bracket 110 for supporting camera functional components. These components may include a lens, a carrier for supporting the lens, a photosensitive element, and structures necessary for autofocus. The specific form of the camera functional components is not limited; the bracket 110 provides overall support for the camera functional components and facilitates attitude adjustment.
[0029] like Figure 2As shown, the adapter frame 200 is fitted onto the bracket 110 and rotatably connected to it. A clearance sufficient for rotation is provided between the adapter frame 200 and the bracket 110, allowing the bracket 110 to rotate relative to the adapter frame 200 around a first axis. The fixed outer frame 300 is fitted onto the adapter frame 200 and rotatably connected to it. A clearance sufficient for rotation is also provided between the fixed outer frame 300 and the adapter frame 200, allowing the adapter frame 200 to rotate relative to the fixed outer frame 300 around a second axis, thereby adjusting the posture of the camera module 100. The bracket 110, adapter frame 200, and fixed outer frame 300 are arranged sequentially from the inside out. Furthermore, the first axis and the second axis are basically perpendicular to each other. Rotation around the first axis clockwise or counterclockwise can be called the first rotation direction, and rotation around the second axis clockwise or counterclockwise can be called the second rotation direction. Regardless of whether the bracket 110 rotates along the first rotation direction, all its movements along the second rotation direction are restricted. Regardless of whether the adapter frame 200 rotates along the second rotation direction, all its movements along the first rotation direction are restricted.
[0030] The bracket 110 is equipped with a first driving member 111, the adapter frame 200 is equipped with a second driving member 211 and a third driving member 212, and the fixed outer frame 300 is equipped with a fourth driving member 310. The first driving member 111 and the second driving member 211 are arranged opposite each other along the direction of the second axis to form a first driving structure, while the third driving member 212 and the fourth driving member 310 are arranged opposite each other along the direction of the first axis to form a second driving structure. Both driving structures can receive control current to generate driving force in corresponding directions.
[0031] like Figures 2-4 As shown, this application may have the following three scenarios in its specific implementation.
[0032] Scenario 1: The bracket 110 rotates relative to the adapter frame 200, while the adapter frame 200 does not rotate relative to the fixed outer frame 300; The first set of drive structures receives control current, and the first drive element 111 interacts with the second drive element 211, driving the bracket 110 to rotate about the first axis relative to the adapter frame 200. The second set of drive structures does not receive control current, and the third drive element 212 and the fourth drive element 310 do not interact, keeping the adapter frame 200 and the fixed outer frame 300 relatively stationary. It should be noted that after the bracket 110 rotates relative to the adapter frame 200 in the first rotation direction under the driving force, the relative position between the two changes, that is, the position of the first drive element 111 relative to the second drive element 211 also changes. However, in the second rotation direction, the position of the first drive element 111 relative to the second drive element 211 remains unchanged. At this time, the adapter frame 200 and the fixed outer frame 300 are relatively stationary. Therefore, regardless of whether it is the first rotation direction or the second rotation direction, the positional relationship between the third driving member 212 and the fourth driving member 310 remains unchanged. Thus, the rotation of the bracket 110 and the first driving member 111 does not affect the positional relationship between the adapter frame 200 and the fixed outer frame 300 (i.e., the third driving member 212 and the fourth driving member 310), and therefore no crosstalk problem will occur.
[0033] Scenario 2: The adapter frame 200 rotates relative to the fixed outer frame 300, while the bracket 110 does not rotate relative to the adapter frame 200; The second set of drive structures receives control current, and the third drive member 212 interacts with the fourth drive member 310, driving the adapter frame 200 to rotate about the second axis relative to the fixed outer frame 300. The first set of drive structures does not receive control current, the first drive member 111 and the second drive member 211 do not interact, and the bracket 110 and the adapter frame 200 are relatively stationary. It should be noted that after the adapter frame 200 is driven and rotates relative to the fixed outer frame 300 in the second rotation direction, the relative position between the two changes, that is, the position of the third drive member 212 relative to the fourth drive member 310 also changes, but in the first rotation direction, the position of the third drive member 212 relative to the fourth drive member 310 does not change. At this time, the bracket 110 and the adapter frame 200 are relatively stationary. Regardless of the first or second rotation direction, the positional relationship between the first driving member 111 and the second driving member 211 remains unchanged. Therefore, the rotation of the adapter frame 200 and the third driving member 212 does not affect the positional relationship between the bracket 110 and the adapter frame 200 (i.e., the first driving member 111 and the second driving member 211), and thus no crosstalk problem will occur.
[0034] Scenario 3: The bracket 110 rotates relative to the adapter frame 200, and the adapter frame 200 rotates relative to the fixed outer frame 300; The first set of drive structures receives control current, and the first drive element 111 interacts with the second drive element 211, driving the bracket 110 to rotate about the first axis relative to the adapter frame 200. Simultaneously, the second set of drive structures receives control current, and the third drive element 212 interacts with the fourth drive element 310, driving the adapter frame 200 to rotate about the second axis relative to the fixed outer frame 300.
[0035] Specifically, as mentioned above, regardless of whether the bracket 110 rotates along the first rotation direction, all its movements along the second rotation direction are restricted. Therefore, the rotation of the bracket 110 around the first axis only affects the positional relationship of the first drive member 111 relative to the second drive member 211 in the first rotation direction. Even if the adapter frame 200 rotates around the second axis, it will not affect the positional relationship of the first drive member 111 relative to the second drive member 211 in the second rotation direction. Similarly, since all its movements along the first rotation direction are restricted regardless of whether the adapter frame 200 rotates along the second rotation direction, the rotation of the adapter frame 200 around the second axis only affects the positional relationship of the third drive member 212 relative to the fourth drive member 310 in the second rotation direction. Even if the bracket 110 rotates around the first axis, it will not affect the positional relationship of the third drive member 212 relative to the fourth drive member 310 in the first rotation direction.
[0036] That is, when the first and second sets of drive structures operate simultaneously under control current, a positional change of the first drive member 111 relative to the second drive member 211 in the first rotational direction does not affect the positional relationship of the third drive member 212 relative to the fourth drive member 310 in the first rotational direction. Therefore, in the first rotational direction, the operation of the first set of drive structures will not generate electromagnetic crosstalk to the operation of the second drive structure. Similarly, a positional change of the third drive member 212 relative to the fourth drive member 310 in the second rotational direction does not affect the positional relationship of the first drive member 111 relative to the second drive member 211 in the second rotational direction. Therefore, in the second rotational direction, the operation of the second drive structure will not generate electromagnetic crosstalk to the operation of the first set of drive structures. In the prior art, since the movement of either the first or second set of drive structures can generate crosstalk to the other, the control system needs to perform additional compensation for the electromagnetic crosstalk between the two sets of drive structures. This application optimizes the prior art, solves the crosstalk problem, and eliminates the need for additional compensation from the control system.
[0037] In order to achieve the aforementioned functions, namely, that all movements of the bracket 110 in the second rotation direction are restricted regardless of whether it rotates in the first rotation direction, and all movements of the adapter frame 200 in the first rotation direction are restricted regardless of whether it rotates in the second rotation direction, the present application also makes the following design.
[0038] In some embodiments, the gimbal module further includes a first positioning part 230, a first connector 500 rotatably connected to the first positioning part 230, a second positioning part 240, and a second connector 600 rotatably connected to the second positioning part 240. For example... Figure 2 , Figure 8 and Figure 9 As shown, the first positioning part 230 and the first connecting member 500 are arranged and abut against each other along the extension direction of the first axis. The first positioning part 230 is fixedly connected to the corresponding inner side of the adapter frame 200, and the first connecting member 500 is fixedly connected to the corresponding outer side of the bracket 110. Thus, the outer side of the bracket 110 is rotatably connected to the inner side of the corresponding adapter frame 200, thereby allowing the bracket 110 to rotate relative to the adapter frame 200 around the first axis. The second positioning part 240 and the second connecting member 600 are arranged and abut against each other along the extension direction of the second axis. The second positioning part 240 is fixedly connected to the corresponding inner side of the fixed outer frame 300, and the second connecting member 600 is fixedly connected to the corresponding outer side of the adapter frame 200. Thus, the inner side of the fixed outer frame 300 is rotatably connected to the corresponding outer side of the adapter frame 200, thereby allowing the adapter frame 200 to rotate relative to the fixed outer frame 300 around the second axis.
[0039] Furthermore, the first connector 500 is provided with a first connecting portion 530, and the first positioning portion 230 is rotatably engaged with the first connecting portion 530. There may be two first connecting portions 530, which are arranged opposite each other on the first shaft and rotatably engaged with the corresponding first positioning portions 230; the first connecting portions 530 and the first positioning portions 230 together form the support position C of the bracket 110 when it rotates relative to the adapter frame 200 (see...). Figure 2 and Figure 7 This allows the bracket 110 to be suspended and supported at the support position C, and the support position C also forms a pivot axis around which the bracket 110 can rotate. That is, the pivot axis formed at the support position C corresponds to the first axis.
[0040] The second connector 600 is provided with a second connecting portion 630, and the second positioning portion 240 is rotatably engaged with the second connecting portion 630. There may be two second connecting portions 630, which are arranged opposite each other on the second shaft and rotatably engaged with their corresponding second positioning portions 240; the second connecting portions 630 and the second positioning portions 240 together form the support position D when the adapter frame 200 rotates relative to the fixed outer frame 300 (see...). Figure 2 and Figure 7 This allows the adapter frame 200 and the camera module 100 suspended within it to be suspended and supported as a whole at the support position D. At the same time, the support position D also forms a pivot axis around which the adapter frame 200 can rotate. That is, the pivot axis formed by the support position D here corresponds to the second axis.
[0041] In one embodiment, both the first connecting portion 530 and the second connecting portion 630 include a rotating arc surface, and both the first positioning portion 230 and the second positioning portion 240 have an abutting arc surface. The rotating arc surface abuts against the corresponding abutting arc surface and allows the rotating arc surface to rotate relative to the abutting arc surface with minimal friction. In related technologies, the rotating arc surface and the abutting arc surface are generally joined by a concave-convex abutment method, which will not be elaborated here.
[0042] In another preferred embodiment, both the first connecting portion 530 and the second connecting portion 630 include a first surface 531, a second surface 532, and a third surface 533 that are interconnected, and the first surface 531, the second surface 532, and the third surface 533 are not coplanar (see [link]). Figure 9 The first positioning part 230 and the second positioning part 240 both have abutting arc surfaces, which abut against the corresponding first surface 531, second surface 532 and third surface 533 respectively, and allow the first surface 531, second surface 532 and third surface 533 to rotate relative to the abutting arc surfaces with less friction. That is, the friction generated between the first surface 531, second surface 532 and third surface 533 as a whole and the abutting arc surface is less than the friction generated between the rotating arc surface and the abutting arc surface.
[0043] Furthermore, this embodiment establishes three dispersed contact positions by setting a first surface 531, a second surface 532, and a third surface 533 that are not coplanar. These three dispersed contact positions constrain the contact arc surface from different directions. Compared to a single constraint on the contact arc surface by a rotating arc surface, this can better restrict all movements of the bracket 110 in the second rotation direction and all movements of the adapter frame 200 in the first rotation direction, resulting in a better anti-crosstalk effect. In particular, the first connecting part 530 and the second connecting part 630 may have other multi-faceted structures. This application does not impose further variations on these structures. The main purpose of this application is to constrain the contact arc surface from multiple directions, thereby improving the positioning effect between the two and preventing swaying (or other movements) between them other than rotation, which would affect the anti-crosstalk effect.
[0044] In some embodiments, the bracket 110 is provided with two opposing first positioning grooves 113 (see Figure 7 The first positioning groove 113 is used to mount the first connector 500 and restrict the position of the first connector 500 relative to the bracket 110. In actual implementation, the first connector 500 can be a sheet-like member capable of elastic deformation in a predetermined direction, so as to assemble with the first positioning groove 113 and achieve miniaturization. More specifically, in conjunction with... Figure 10As shown, the first connector 500 includes two first fixed sections 510 and a first elastic section 520, with the first elastic section 520 connected between the two first fixed sections 510. The two first fixed sections 510 are respectively connected within corresponding first positioning grooves 113, and a first connecting portion 530 is disposed within the first elastic section 520. When the first connecting portion 530 abuts against the first positioning portion 230, the first elastic section 520 can apply an elastic force toward the first positioning portion 230 to the first connecting portion 530. Two opposing second positioning grooves 341 are provided on the inner side of the fixed outer frame 300. The second connector 600 can also be a sheet-like component capable of elastic deformation in a predetermined direction, so as to assemble with the second positioning grooves 341 and achieve miniaturization. The second connector 600 includes two second fixed sections 610 and a second elastic section 620, with the second elastic section 620 connected between the two second fixed sections 610. Two second fixed sections 610 are respectively connected to the corresponding second positioning grooves 341, and a second connecting part 630 is provided in the second elastic section 620. Similarly, when the second connecting part 630 abuts against the second positioning part 240, the second elastic section 620 can apply an elastic force toward the second positioning part 240 to the second connecting part 630.
[0045] like Figure 6 , Figure 10 and Figure 15 As shown, in some embodiments, the first fixing segment 510 is provided with a plurality of mutually spaced first support portions 511. The first support portions 511 abut against the groove wall of the corresponding first positioning groove 113, and the second fixing segment 610 is provided with a plurality of mutually spaced second support portions 611, which abut against the groove wall of the corresponding second positioning groove 341. The first support portions 511 and the second support portions 611 can be protrusions, bosses, or other structures that enable the fixing segment to partially contact the groove wall. When the first connector 500 and the second connector 600 are inserted into the corresponding positioning grooves, the mutually spaced support portions can reduce the contact area between the first connector 500 and the first positioning groove 113, and between the second connector 600 and the second positioning groove 341, thereby reducing the frictional resistance during the assembly process.
[0046] Furthermore, the first support portion 511 separates the first fixing section 510 from the groove wall of the first positioning groove 113, and a first adhesive space a can be formed between the first fixing section 510 and the first positioning groove 113 (see...). Figure 15The second support portion 611 separates the second fixing section 610 from the groove wall of the second positioning groove 341, and a second adhesive space can be formed between the second fixing section 610 and the second positioning groove 341. During assembly, adhesive can be injected from the first positioning groove 113 and the second positioning groove 341. The adhesive can flow along the interval between adjacent support portions and fill the first adhesive space a and the second adhesive space. After the adhesive cures, it can improve the groove wall strength of the first positioning groove 113 and the second positioning groove 341, thereby improving the side wall strength of the bracket 110 and the fixed outer frame 300. In other embodiments, the first support portion 511 can also be provided on the groove wall of the first positioning groove 113, in which case the first support portion 511 abuts against the first fixing section 510; the second support portion 611 can also be provided on the groove wall of the second positioning groove 341, in which case the second support portion 611 abuts against the second fixing section 610. Alternatively, it is permissible for the first support portion 511 to be disposed in the first fixed section 510 and the second support portion 611 to be disposed in the groove wall of the second positioning groove 341; or for the first support portion 511 to be disposed in the groove wall of the first positioning groove 113 and the second support portion 611 to be disposed in the second fixed section 610.
[0047] like Figure 10 As shown, in some preferred embodiments, the first connector 500 further includes two first bending segments 540, each first bending segment 540 being connected between the corresponding first fixed segment 510 and the first elastic segment 520, such that the first fixed segment 510 and the first elastic segment 520 are not coplanar.
[0048] In contrast, if a flat design is adopted in which the first fixed section 510 and the first elastic section 520 are coplanar, the first fixed section 510 must be set close to the side wall of the first positioning groove 113 facing the adapter frame 200 in order to meet the contact requirements between the first elastic section 520 and the first positioning part 230. This means that the wall thickness of the groove wall of the first positioning groove 113 facing the adapter frame 200 needs to be reduced from the initial design stage. When the first elastic section 520 is elastically pre-compressed to deform it, the deformation force will directly act on the part of the first fixed section 510 located in the first positioning groove 113, thereby squeezing the side wall of the first positioning groove 113, which can easily lead to the damage of the side wall.
[0049] This application, by setting a first bending section 540, makes the first fixed section 510 and the first elastic section 520 non-coplanar. As a result, the first fixed section 510 can be basically arranged in the middle part of the side wall of the bracket 110, so that the side wall of the first positioning groove 113 can more evenly resist the elastic force transmitted through the first fixed section 510 when the first elastic section 520 deforms, significantly reducing the risk of damage.
[0050] The second connector 600 also includes two second bending segments 640, each second bending segment 640 connecting between the corresponding second fixed segment 610 and second elastic segment 620, such that the second fixed segment 610 and the second elastic segment 620 are not coplanar. The effect of the second bending segment 640 is the same as that of the first bending segment 540, and will not be described in detail here.
[0051] In actual implementation, the first bending segment 540 and the second bending segment 640 can be circular arc transition structures.
[0052] It should be noted that the first positioning part 230 is a rigid structure, while the first connecting member 500 is an elastic structure. The preload is applied to the first positioning part 230 by the first connecting member 500, and the first elastic segment 520 of the first connecting member 500 protrudes relative to the first fixed segment 510 through the first bending segment 540. Similarly, the second positioning part 240 and the second connecting member 600 have the same structure, and will not be described in detail here.
[0053] In some embodiments, a first hollow groove 521 and a second hollow groove 522 are provided on both the first elastic segment 520 and the second elastic segment 620. The second hollow groove 522 is spaced apart from the first hollow groove 521 in the width direction of the corresponding elastic segment. When the first elastic segment 520 and the second elastic segment 620 are subjected to preload, the deformation is mainly concentrated at the second hollow groove 522 of the first elastic segment 520 and the second elastic segment 620, thereby making the deformation behavior more controllable and easier to occur.
[0054] In actual implementation, the two first hollowed-out grooves 521 are symmetrically distributed about the first positioning part 230 or the second positioning part 240. Through the above symmetrical arrangement, the first elastic segment 520 and the second elastic segment 620 are subjected to pre-pressure, and the force on both sides is more uniform and the deformation distribution is more consistent.
[0055] Simultaneously, each first hollowed-out groove 521 corresponds to two second hollowed-out grooves 522, and the two second hollowed-out grooves 522 are symmetrically distributed about the first hollowed-out grooves 521. This arrangement helps guide deformation to the area where the second hollowed-out grooves 522 are located, making the deformation of the first elastic segment 520 and the second elastic segment 620 more defined and controllable. In actual implementation, the second hollowed-out grooves 522 can be notches formed in the first elastic segment 520 and the second elastic segment 620.
[0056] like Figure 2 and Figures 5-7As shown, in some embodiments, the first driving member 111 includes a first coil, and the second driving member 211 includes a first magnet. A first receiving groove 112 is provided on one side of the bracket 110, and a second receiving groove 221 is provided on the side of the adapter frame 200 corresponding to the first receiving groove 112. The first coil is received in the first receiving groove 112, and the first magnet is received in the second receiving groove 221, so that the first coil and the first magnet are opposite each other.
[0057] When a driving current is applied to the first coil, it interacts with the first magnet to generate a driving force. Since the first coil is located on the bracket 110 and the first magnet is located on the adapter frame 200, this driving force enables the bracket 110 to rotate relative to the adapter frame 200 in a first rotation direction. By changing the magnitude and direction of the driving current in the first coil, the rotational force and direction of the bracket 110 can be adjusted.
[0058] The third driving component 212 includes a second magnet, and the fourth driving component 310 includes a second coil. A third receiving groove 222 is provided on the outer side of the adapter frame 200, and a fourth receiving groove 320 is provided on the side of the fixed outer frame 300 corresponding to the third receiving groove 222. The openings of the third receiving groove 222 and the fourth receiving groove 320 are arranged opposite to each other. The second magnet is received in the third receiving groove 222, and the second coil is received in the fourth receiving groove 320, so that the second magnet and the second coil are opposite each other.
[0059] When a driving current is applied to the second coil, it interacts with the second magnet to generate a driving force. Since the second magnet is located in the adapter frame 200 and the second coil is located in the fixed outer frame 300, this driving force can drive the adapter frame 200 to rotate relative to the fixed outer frame 300 in a second rotation direction. By changing the magnitude and direction of the driving current in the second coil, the rotational force and direction of the adapter frame 200 can be adjusted.
[0060] like Figures 11-14 As shown, in some embodiments, the fixed outer frame 300 is provided with a window 342, and the gimbal module also includes a first electrical connector 810 and a second electrical connector 820 (see...). Figure 5 ) and the first flexible circuit board 700.
[0061] The first electrical connector 810 is located in window 342 and is electrically connected to the fourth drive member 310. Window 342 provides installation and wiring space for the first electrical connector 810, allowing the first electrical connector 810 to extend from the inside of the fixed outer frame 300 to a position that facilitates connection to an external power source.
[0062] In this embodiment, the first electrical connector 810 is used to supply external power to the fourth drive unit 310. The second electrical connector 820 is electrically connected to the first drive unit 111 and the camera module 100. For example, the second electrical connector 820 can be soldered to the corresponding contacts of the first coil and the camera module 100. The first flexible circuit board 700 is electrically connected to the first electrical connector 810 and the second electrical connector 820, respectively. Thus, external power and control signals can be transmitted to the camera module 100, the first drive unit 111, and the fourth drive unit 310 through the first electrical connector 810, the first flexible circuit board 700, and the second electrical connector 820.
[0063] In some embodiments, the first flexible circuit board 700 includes a first segment 710, a second segment 720, and a third segment 730 connected in sequence. The first segment 710 is located at the bottom of the camera module 100 and is electrically connected to the first drive member 111 and the camera module 100. Specifically, the first segment 710 can be connected to a second electrical connector 820, through which electrical connection with the first coil and the camera module 100 is achieved. The second segment 720 extends outward from one side of the first segment 710 and can undergo adaptive deformation when the gimbal module moves. The third segment 730 extends along the outer periphery of the fixed outer frame 300 and is electrically connected to the first electrical connector 810 located in the window 342, thereby leading out the internal wiring.
[0064] Furthermore, the gimbal module also includes a housing 400, which is fitted onto the fixed outer frame 300. The outer wall of the fixed outer frame 300 is provided with a clearance portion 343 spaced apart from the housing 400. This clearance portion 343 can be a space formed by a partial inward recess in the outer wall of the fixed outer frame 300. The third segment 730 is disposed within the clearance portion 343, so that the third segment 730 can undergo adaptive deformation when the adapter frame 200, camera module, etc., move.
[0065] The first segment 710, the second segment 720, and the third segment 730 can be continuously formed from the same flexible substrate. The conductive lines of the first flexible circuit board 700 can be copper foil lines, and an insulating covering layer is provided outside the conductive lines. The corresponding conductive areas can be exposed at the locations where soldering or electrical connection is required, and these conductive areas extend from the outer casing 400.
[0066] In some embodiments, the first electrical connector 810 includes a second flexible circuit board 811 and a reinforcing plate 812. The insulating surface of the second flexible circuit board 811 is fixedly connected to the reinforcing plate 812, and the reinforcing plate 812 is fixedly connected to the housing 400, thereby reliably fixing the second flexible circuit board 811 to the housing 400. The second flexible circuit board 811 is electrically connected to the first flexible circuit board 700 and the fourth drive member 310, forming an interface between the gimbal module and an external power supply or control circuit. The reinforcing plate 812 can improve the rigidity and flatness of the connection area to facilitate welding. At the same time, the reinforcing plate 812 is in close contact with the insulating surface of the second flexible circuit board 811, ensuring electrical insulation even when a metal reinforcing plate 812 is used.
[0067] When the gimbal module is working, the control system provides drive current to the first and second coils according to the attitude change. The bracket 110 and the adapter frame 200 rotate under the corresponding driving force, causing the camera module 100 to change its attitude. The second segment 720 and the third segment 730 of the first flexible circuit board 700 adapt to the movement. Since the first and second drive structures remain relatively stationary when rotating in non-corresponding directions, the movements in the two directions are less likely to couple with each other, resulting in more stable image stabilization.
[0068] It should be noted that the bracket 110, adapter frame 200, fixed outer frame 300, and outer shell 400 can be made of plastic, metal, or composite materials. The first connector 500 and the second connector 600 can be made of stainless steel, copper alloy, or other elastic materials. The first magnet and the second magnet can be made of permanent magnet materials, and the first coil and the second coil can be made of wound coils or planar coils. The adhesive can be selected from thermosetting adhesives, light-curing adhesives, or other structural adhesives depending on the materials of the connectors and the frame.
