Therefore, the statements "in one embodiment", "in some embodiments", "in other some embodiments", "in other some embodiments" and the like appearing in different places in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized. The terms "include", "contain", "have" and their variants mean "include but not limited to", unless otherwise specifically emphasized.

[0141] Referring to FIG. 1, a gimbal camera module 10 in the related art includes a first support 11, a second support 12, a camera module 13, an anti-shake motor 14, and a flexible circuit board 15. The first support 11 can rotate relative to the second support 12 around a first axis X and a second axis Y. The camera module 13 is mounted on the first support 11 and includes a lens and an image sensor. The anti-shake motor 14 is arranged between the first support 11 and the second support 12 and is configured to drive the first support 11 to rotate around the first axis X and the second axis Y, so that the camera module 13 can rotate around the first axis X and the second axis Y, and motion compensation can be achieved in a shaking scene. The plane in which the first axis X and the second axis Y are located is perpendicular to the axis (third axis Z) of the camera module 13. The flexible circuit board 15 is arranged beside the camera module 13 and is S-shaped. The flexible circuit board 15 is located outside the second support 12. One end of the flexible circuit board 15 is configured to be connected to an external circuit board, and the other end is connected to the camera module 13. The flexible circuit board 15 can be used as a medium for transmitting current to the image sensor and the lens focusing motor of the camera module 13, and the flexible circuit board 15 can reduce the resistance moment of the camera module 13 when rotating.

[0142] In the plane in which the first axis X and the second axis Y are located, the area occupied by the flexible circuit board 15 is equivalent to the area occupied by the camera module 13. When applied to an electronic device (such as a mobile phone), the flexible circuit board 15 occupies a large space, which is not conducive to arranging a large-area image sensor. When the camera module 13 rotates around the first axis X or the second axis Y, the flexible circuit board 15 will be deformed and generate a large resistance moment. This is not conducive to the anti-shake motor 14 driving the camera module 13 to rotate by a large angle for anti-shake, and the optical anti-shake effect is poor.

[0143] Referring to FIG. 2, a folding circuit board 20 in the related art includes a fixed plate 21, a connecting portion 22, and a movable plate 23. The fixed plate 21 and the movable plate 23 are connected by the connecting portion 22. The connecting portion 22 has a first folding portion 22a extending along a first axis X and a second folding portion 22b extending along a second axis Y. One end of the first folding portion 22a is connected to one end of the second folding portion 22b. The first axis X and the second axis Y are different. The plane in which the first axis X and the second axis Y are located is perpendicular to the axis (third axis Z) of the camera module. The fixed plate 21 is configured to be connected to an external circuit board, and the movable plate 23 is configured to mount an image sensor 24. The folding circuit board 20 can be used as a medium for transmitting current to the image sensor 24. The movable plate 23 can be driven to rotate around the first axis X and the second axis Y by an anti-shake motor, so that the image sensor 24 can rotate around the first axis X and the second axis Y, and motion compensation can be achieved in a shaking scene. The connecting portion 22 of the folding circuit board 20 can reduce the resistance moment of the image sensor 24 when rotating to a certain extent.

[0144] The first folding part 22a and the second folding part 22b are long in length. The first folding part 22a and the second folding part 22b are arranged on the outer periphery of the movable plate 23, occupy a large area in the plane of the first axis X and the second axis Y, and occupy a large space when applied to an electronic device (such as a mobile phone), which is not conducive to arranging a large-area image sensor 24. When the movable plate 23 rotates around the first axis X or the second axis Y, the stress state of the first folding part 22a and the second folding part 22b affects each other, and the long first folding part 22a and the second folding part 22b will be deformed, generating a large resistance moment. It is not conducive to the driving of the image sensor 24 by the anti-shake motor to rotate by a large angle for anti-shake, and the optical anti-shake effect is poor.

[0145] Referring to (a) and (b) in FIG. 3, an embodiment of the present application provides an electronic device 1, which includes a device shell 2000 and a camera 1000 arranged on the device shell 2000. The device shell 2000 is used to mount the components of the electronic device 1 and provide protection, reducing the damage of the components caused by external influences. The camera 1000 is used to take pictures to capture still images or videos. The device shell 2000 can be configured with one or more cameras 1000.

[0146] The electronic device 1 can be a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer, an electronic book reader, a netbook, a personal digital assistant, a wearable device, an augmented reality (AR) device, a virtual reality (VR) device, a television, a drone, a sports camera, a driving recorder, a vehicle-mounted device, a robot, a teller machine, etc.

[0147] Taking the electronic device 1 as a mobile phone as an example. The electronic device 1 includes a camera 1000, a device shell 2000, and a display screen 3000. The device shell 2000 includes a back cover 2100 and a middle frame 2200. The display screen 3000 and the back cover 2100 are arranged on opposite sides of the middle frame 2200, respectively. The display screen 3000 and the middle frame 2200 can be connected by adhesion or the like. The middle frame 2200 and the back cover 2100 can be connected by adhesion, buckling or the like. The middle frame 2200 and the back cover 2100 can also be an integral structure.

[0148] As shown in (a) of FIG. 3, the camera 1000 can be arranged on the middle frame 2200 as a front-facing camera. As shown in (b) of FIG. 3, the camera 1000 can be arranged on the back cover 2100 as a rear-facing camera.

[0149] The electronic device 1 can further include a battery, a mainboard, an earpiece, a loudspeaker, a gyroscope, an accelerometer, an ambient light sensor, and the like, which can be disposed on the middle frame 2200. The mainboard can be provided with a processor, and the driving chip can be disposed on the camera 1000.

[0150] In some embodiments, the camera 1000 includes an anti-shake gimbal 100 and a camera module 200. The camera module 200 is disposed on the anti-shake gimbal 100. The anti-shake gimbal 100 is used to drive the camera module 200 to rotate around a predetermined axis within a certain range, so as to make the camera module 200 perform motion compensation in a shaking scene, and realize optical anti-shake. This scheme is suitable for photographing or video shooting in a shaking scene such as user motion and handheld electronic device 1.

[0151] In some embodiments, the camera module 200 includes an image sensor 210 and a lens 220. The light receiving surface of the image sensor 210 is perpendicular to the third axis Z, and the image sensor 210 and the light exit side of the lens 220 are oppositely disposed. The lens 220 images the shooting scene on the light receiving surface of the image sensor 210. The image sensor 210 converts the light image on the light receiving surface of the image sensor 210 into an electrical signal by using the photoelectric conversion function of the photoelectric device, so as to capture an image or a video.

[0152] The lens 220 can include one or more optical lenses. When the lens 220 includes multiple optical lenses, the multiple optical lenses can be stacked along the optical axis direction of the lens 220. By designing the number of optical lenses and the parameters of each lens, a lens 220 with different characteristics such as wide-angle, standard, and telephoto can be obtained.

[0153] The image sensor 210 can be a charge coupled device (CCD), a complementary metal oxide semiconductor (CMOS), or a thin film transistor (TFT), and the like.

[0154] In order to facilitate the description of the positions and directions of the folding circuit board structure 150, the anti-shake gimbal 100, and the camera module 200 provided in the embodiments of the present application, the directions of the first axis X and the second axis Y are defined as two directions on a reference plane. The direction perpendicular to the reference plane is defined as the third axis Z. The optical axis / axis of the camera module 200 in the initial state without shaking is the third axis Z. The first axis X and the second axis Y form a predetermined included angle, such as 80°, 90°, 120°, and the like. The first axis X and the second axis Y form a 90° angle, and the first axis X, the second axis Y, and the third axis Z are perpendicular to each other.

[0155] In the setting of the anti-shake gimbal 100, referring to FIGS. 4-9, the anti-shake gimbal 100 comprises a first support 110, a second support 120, an intermediate support 130, a first anti-shake motor 140, and a folding circuit board structure 150. The first support 110 is movably mounted on the second support 120 through the intermediate support 130, and the first support 110 can rotate relative to the second support 120 around a first axis X and a second axis Y. The first support 110 is used to mount a camera module 200, and the camera module 200 can rotate relative to the second support 120 around the first axis X and the second axis Y following the first support 110.

[0156] The first support 110 and the camera module 200 can be an assembled structure, and part of the structure of the first support 110 and the camera module 200 can also be an integrated structure. The second support 120 can be directly or indirectly mounted on the shell of an electronic device. For example, the second support 120 is mounted on a predetermined part, and the predetermined part is mounted on the shell of the electronic device, so that the second support 120 is indirectly mounted on the shell of the electronic device.

[0157] The first anti-shake motor 140 is used to drive the first support 110 or the camera module 200 to rotate within a certain range around the first axis X and the second axis Y, so as to make the camera module 200 do motion compensation to realize optical anti-shake in a shaking scene.

[0158] When the camera module 200 rotates around the first axis X and the second axis Y, the folding circuit board structure 150 can realize the transmission of current and / or electrical signals between the outside of the anti-shake gimbal 100 and the camera module 200. In combination with FIG. 6, external current can be transmitted to the image sensor 210 through the folding circuit board structure 150. The image electrical signal of the image sensor 210 can be transmitted to the outside of the anti-shake gimbal 100, such as to the mainboard, through the folding circuit board structure 150.

[0159] FIG. 10(a)-(f) are simulation diagrams of the first support 110 of the anti-shake gimbal 100 rotating to a plurality of positions relative to the second support 120 around the first axis X. The first support 110 can rotate within a certain angle range around the first axis X. As shown in FIG. 10(a), the first support 110 is in an initial position. In combination with FIG. 10(b), (c), the first support 110 rotates around the first axis X towards one side. As shown in FIG. 10(d), the first support 110 is in the initial position. In combination with FIG. 10(e), (f), the first support 110 rotates around the first axis X towards the other side.

[0160] Figures 11(a) to (f) are respectively simulation diagrams of the first support 110 in the anti-shake holder 100 rotating to a plurality of positions relative to the second support 120 about the second axis Y. The first support 110 can rotate within a certain angle range about the second axis Y. As shown in Figure 11(a), the first support 110 is in an initial position. In combination with Figures 11(b) and (c), the first support 110 rotates about the second axis Y to one side. As shown in Figure 11(d), the first support 110 is in the initial position. In combination with Figures 11(e) and (f), the first support 110 rotates about the second axis Y to the other side.

[0161] In order to facilitate the camera module 200 being mounted on the first support 110, in some embodiments, referring to Figures 5 and 6, the first support 110 has a first accommodating cavity 111, and the camera module 200 is at least partially arranged in the first accommodating cavity 111. The first support 110 serves as a carrier of the camera module 200 and protects the camera module 200. The first support 110 can rotate relative to the second support 120 about the first axis X and the second axis Y, so that the camera module 200 rotates relative to the second support 120 about the first axis X and the second axis Y.

[0162] For example, in the case that the first support 110 and the camera module 200 are in an assembled structure, the first support 110 can be in a frame shape, and the camera module 200 is fixed inside the first support 110.

[0163] In order to facilitate the first support 110 being mounted on the second support 120, in some embodiments, referring to Figures 5 and 6, the second support 120 has a second accommodating cavity 121, and the first support 110 is at least partially arranged in the second accommodating cavity 121, and the first anti-shake motor 140 is arranged in the second accommodating cavity 121. The first support 110 and the first anti-shake motor 140 are arranged in the second accommodating cavity 121 of the second support 120, and the second support 120 protects the first support 110 and the first anti-shake motor 140.

[0164] For example, the second support 120 can be in a frame shape, and the first support 110 is located inside the second support 120.

[0165] In the setting of the intermediate support 130, referring to FIG. 5, the intermediate support 130 comprises a body part 131, a first extension arm 132 and a second extension arm 133. In combination with FIG. 6 and FIG. 7, the lens 220 in the camera module 200 is close to the surface of the object to be photographed, which is called the lens object side 200a. The body part 131 is arranged on the side of the lens object side 200a of the camera module 200, and the body part 131 and the lens object side 200a are spaced apart, so that the first support 110 can rotate in a certain space, and the body part 131 is avoided from colliding with the first support 110 when the first support 110 rotates. In combination with (a) to (f) in FIG. 10, in the process of rotating the first support 110 around the first axis X, the first support 110 and the body part 131 avoid each other and cannot interfere with each other.

[0166] One end of the first extension arm 132 is connected to the body part 131, and the other end of the first extension arm 132 is hinged to the first support 110, and the hinge axis of the first extension arm 132 serves as the first axis X of the first support 110 relative to the second support 120. One end of the second extension arm 133 is connected to the body part 131, and the other end of the second extension arm 133 is hinged to the second support 120, and the hinge axis of the second extension arm 133 serves as the second axis Y of the first support 110 relative to the second support 120.

[0167] Referring to FIG. 7 to FIG. 9, in the process of rotating the first support 110 around the first axis X relative to the second support 120, the second extension arm 133 remains stationary relative to the second support 120, and the first extension arm 132 does not follow the first support 110 to rotate around the first axis X, so that the intermediate support 130 remains stationary relative to the second support 120.

[0168] In the process of rotating the first support 110 around the second axis Y relative to the second support 120, the first extension arm 132 follows the first support 110 to rotate around the second axis Y, and the second extension arm 133 rotates around the second axis Y relative to the second support 120, so that the intermediate support 130 follows the first support 110 to rotate around the second axis Y.

[0169] In the setting of the shape of the body part 131, referring to FIG. 5 and FIG. 7, the body part 131 can be arranged along the edge of the lens object side 200a of the camera module 200. The body part 131 can be arranged along the edge of the lens object side 200a to form a straight line, a curve or a structure of multiple lines, or can be arranged along the edge of the lens object side 200a to form a ring structure. The body part 131 can avoid the optical path of the camera module 200, and external light can smoothly enter the camera module 200 for optical imaging. When the intermediate support 130 is applied to the anti-shake gimbal 100 or the camera device 1000, the body part 131 and the lens object side 200a of the camera module 200 are arranged to be spaced apart.

[0170] In setting the shape of the body part 131, the body part 131 can be linear, arc-shaped, ring-shaped, or multi-segmented. The body part 131 is arranged at a predetermined distance position on the lens object side 200a of the camera module 200, and the specific shape is set as needed, and the body part 131 needs not to block the light path of the camera module 200.

[0171] For example, the body part 131 can be located on a reference plane, and the first axis X and the second axis Y are parallel to the reference plane. Arranging the body part 131 on the reference plane makes the structure compact, facilitating the molding and assembly of the body part 131. In addition, the body part 131 can also be arranged as a three-dimensional structure, having multiple components located on different planes, and the multiple components are connected.

[0172] In setting the positions of the first extension arm 132 and the second extension arm 133, the first extension arm 132 and the second extension arm 133 are connected to the side edge 131a of the body part 131 away from the axis (third axis Z) of the camera module 200. Arranging the first extension arm 132 and the second extension arm 133 on the outer side of the body part 131 can make the folded circuit board structure 150 smaller in limited space, and occupy less space. This facilitates the hinged assembly of the first extension arm 132 and the first support 110, and the hinged assembly of the second extension arm 133 and the second support 120.

[0173] In setting the shape of the first extension arm 132 and the second extension arm 133, the first extension arm 132 and the second extension arm 133 can extend along the direction of the third axis Z. This makes it easy to mold the intermediate support 130, facilitates the hinged assembly of the first extension arm 132 to the first support 110 and the hinged assembly of the second extension arm 133 to the second support 120, occupies less space, and makes the structure compact. In addition, the first extension arm 132 and the second extension arm 133 can also extend at an angle relative to the third axis Z.

[0174] In order to make the intermediate support 130 occupy less space, in some embodiments, referring to FIGS. 8 and 9, the projection of the intermediate support 130 on the vertical plane of the third axis Z is located within the projection of the second support 120. Limiting the intermediate support 130 within the range of the second support 120 can reduce the space occupied by the intermediate support 130, make the structure of the anti-shake holder 100 compact, and meet the requirement that the first support 110 is supported by the intermediate support 130 on the second support 120, so that the first support 110 can rotate relative to the second support 120 around the first axis X and the second axis Y.

[0175] In setting the number of the first extension arm 132 and the second extension arm 133, the number of the first extension arm 132 is at least one, and the number of the second extension arm 133 is at least one.

[0176] In some embodiments, referring to FIG. 5, FIG. 7 and FIG. 9, the first extension arms 132 are arranged in pairs and are spaced apart along the direction of the first axis X. Two first extension arms 132 are hinged to the first support 110, so that the intermediate support 130 is stably rotated relative to the first support 110 about the first axis X, and the connection reliability is improved.

[0177] In other embodiments, the intermediate support 130 can be provided with one first extension arm 132, which is hinged to the first support 110, so that the intermediate support 130 is rotated relative to the first support 110 about the first axis X.

[0178] In some embodiments, referring to FIG. 5, FIG. 8 and FIG. 9, the second extension arms 133 are arranged in pairs and are spaced apart along the direction of the second axis Y. Two second extension arms 133 are hinged to the second support 120, so that the intermediate support 130 is stably rotated relative to the second support 120 about the second axis Y, and the connection reliability is improved.

[0179] In other embodiments, the intermediate support 130 can be provided with one second extension arm 133, which is hinged to the second support 120, so that the intermediate support 130 is rotated relative to the second support 120 about the second axis Y.

[0180] In order to facilitate the assembly of the intermediate support 130 between the first support 110 and the second support 120, in some embodiments, referring to FIG. 5, FIG. 7 and FIG. 9, the first support 110 is provided with a first mounting slot 112, and the first extension arm 132 is hinged to the first mounting slot 112 through a first support part 134, which is arranged on the first extension arm 132 and located in the first mounting slot 112. The first extension arm 132 is hinged to the first mounting slot 112 of the first support 110 through the first support part 134, which is easy to assemble in structure, can stably rotate the first extension arm 132 relative to the first support 110 about the first axis X, and reduce the friction between the first extension arm 132 and the first support 110 during relative movement.

[0181] The second support 120 is provided with a second mounting slot 122, and the second extension arm 133 is hinged to the second mounting slot 122 through a second support part 135, which is arranged on the second extension arm 133 and located in the second mounting slot 122. The second extension arm 133 is hinged to the second mounting slot 122 of the second support 120 through the second support part 135, which is easy to assemble in structure, can stably rotate the second extension arm 133 relative to the first support 110 about the second axis Y, and reduce the friction between the second extension arm 133 and the second support 120 during relative movement. The first support part and the second support part can be bearings or balls.

[0182] For example, referring to FIG. 5, the number of the first extension arms 132 can be one or two. The first support 110 has a first mounting slot 112 corresponding to the first extension arm 132. The first bearing is a bearing. The bearing includes an outer ring 134a, an inner ring 134b, and a plurality of rolling elements between the outer ring 134a and the inner ring 134b. The first extension arm 132 is provided with a connecting column, the inner ring 134b of the bearing is fixed on the connecting column 134c, and the outer ring 134a of the bearing is fixed (such as welding, gluing, etc.) in the first mounting slot 112. The rotation connection between the first extension arm 132 and the first support 110 around the first axis X is realized by the bearing, and the movement friction between the first extension arm 132 and the first support 110 is small.

[0183] For example, the pair of first extension arms 132 are arranged at intervals along the first axis X, and the first support 110 has two first mounting slots 112. The first bearing is a ball bearing, the first extension arm 132 is provided with a ball bearing, and the shape of the first mounting slot 112 and the shape of the ball bearing exposed outside the first extension arm 132 are matched, so that the ball bearing can move relative to the wall surface of the first mounting slot 112. The rotation connection between the first extension arm 132 and the first support 110 around the first axis X is realized by the ball bearing, and the movement friction between the first extension arm 132 and the first support 110 is small.

[0184] In some embodiments, referring to FIGS. 5 and 6, the first support 110 is in the shape of a frame, and the first mounting slot 112 is located on the outer side of the first support 110. The first extension arm 132 and the first bearing 134 can be arranged on the outer periphery of the first support 110, so that the first support 110 occupies a smaller area and has a compact structure.

[0185] In some embodiments, referring to FIGS. 5 and 6, the second support 120 is in the shape of a frame, and the second mounting slot 122 is located on the inner side of the second support 120. The second extension arm 133 and the second bearing 135 can be arranged on the inner periphery of the second support 120, so that the second support 120 occupies a smaller area and has a compact structure.

[0186] When the first anti-shake motor 140 is arranged, the first anti-shake motor 140 can be a voice coil motor (VCM), a piezoelectric motor, or a shape memory alloy (SMA) motor. The above anti-shake motors can drive the first support 110 or the camera module 200 to rotate within a certain range around the first axis X and the second axis Y, so as to compensate for the movement of the camera module 200 in a shaking scene and realize optical anti-shake.

[0187] When the first anti-shake motor 140 is arranged between the first support 110 and the second support 120, referring to FIG. 12 and FIG. 13, the first anti-shake motor 140 includes a first rotary driving part 140a and a second rotary driving part 140b, the first rotary driving part 140a is used to drive the camera module 200 to rotate relative to the second support 120 around the first axis X, and the second rotary driving part 140b is used to drive the first support 110 or the camera module 200 to rotate relative to the second support 120 around the second axis Y.

The first support 110 is directly driven by the first rotary driving part 140a to rotate relative to the second support 120 around the first axis X. The first support 110 is directly driven by the second rotary driving part 140b to rotate relative to the second support 120 around the second axis Y. This assembly mode occupies a smaller space or area, so that the anti-shake holder 100 or the camera device 1000 has a compact structure.

[0190] The second assembly mode of the first anti-shake motor 140: referring to FIG. 13, the camera module 200 is arranged on the first support 110, the fixed part of the first rotary driving part 140a is fixed on the intermediate support 130, and the movable part of the first rotary driving part 140a is fixed on the first support 110.

The intermediate support 130 is driven by the second rotary driving part 140b to rotate relative to the second support 120 around the second axis Y, so as to make the first support 110 connected with the intermediate support 130 rotate relative to the second support 120 around the second axis Y. This assembly mode can also realize the rotation of the first support 110 relative to the second support 120 around the first axis X and the second axis Y.

[0191] The first anti-shake motor 140 is a voice coil motor, and the first assembly mode of the first anti-shake motor 140 is taken as an example for description below.

[0192] Referring to FIG. 5, FIG. 6 and FIG. 9, the first anti-shake motor 140 comprises a first magnetic assembly 141 and a second magnetic assembly 142 arranged adjacently.

The center of the first anti-shake coil 1412 is at a certain distance from the first axis X or the second axis Y, so that the first Lorentz force can generate a moment around the first axis X or the second axis Y. By changing the current direction of the first anti-shake coil 1412, the direction of the first Lorentz force can be changed to be positive or negative along the third axis Z.

The first anti-shake coil 1412 and the second anti-shake coil 1422 are subjected to Lorentz force, and the first anti-shake magnetic member 1411 and the second anti-shake magnetic member 1421 are subjected to the reaction force of the Lorentz force, so that the first support 110 is rotated relative to the second support 120 around the first axis X and the second axis Y.

[0200] For example, the first magnetic assembly 141 and the second magnetic assembly 142 are arranged on opposite sides of the first axis X respectively.

The number of the first magnetic assembly 141 is at least one, and the number of the second magnetic assembly 142 is at least one. By changing the number of the first magnetic assembly 141 and the second magnetic assembly 142, or changing the input current of the anti-shake coil, the driving torque of the first support 110 can be changed.

[0203] For example, referring to FIG. 6, two first magnetic assemblies 141 and two second magnetic assemblies 142 are arranged on the first support 110 and the second support 120, wherein one first magnetic assembly 141 is arranged on each of two opposite first side walls, and one second magnetic assembly 142 is arranged on each of the other two opposite first side walls.

The first circuit suspension wire 152 and the second circuit suspension wire 153 are electrically connected through the first communication part 151.

[0213] Among them, the first communication part 151, the first circuit suspension wire 152 and the second circuit suspension wire 153 all have conductive traces, so that the first circuit suspension wire 152 and the second circuit suspension wire 153 are electrically connected through the first communication part 151, and the transmission of electric current and / or electric signal can be realized.

[0214] The first circuit suspension wire 152 is divided into the first fixed part 1521, the first flexible part 1522 and the first connecting part 1523, and the second circuit suspension wire 153 is divided into the second fixed part 1531, the second flexible part 1532 and the second connecting part 1533, which is for the convenience of describing the structure and function of each part. The first fixed part 1521, the first flexible part 1522 and the first connecting part 1523 can be an integral structure. The second fixed part 1531, the second flexible part 1532 and the second connecting part 1533 can be an integral structure.

[0215] The first flexible part 1522 is bent to extend at least partially along the third axis Z. The first flexible part 1522 can be bent to extend along the third axis Z partially, or can be bent to extend along the third axis Z entirely.

[0216] The second flexible part 1532 is bent to extend at least partially along the third axis Z. The second flexible part 1532 can be bent to extend along the third axis Z partially, or can be bent to extend along the third axis Z entirely.

[0217] The first flexible part 1522 (the second flexible part 1532) is bent to extend at least partially along the third axis Z. The center lines of the plurality of bending sections of the first flexible part 1522 (the second flexible part 1532) can be parallel to the third axis Z, or the center lines of the plurality of bending sections of the first flexible part 1522 (the second flexible part 1532) can form a predetermined angle with the third axis Z, so that the opposite ends of the part extending along the third axis Z are located on different vertical planes of the third axis Z.

[0218] The two components or the two positions are electrically connected, which can be direct electrical connection, or indirect electrical connection through a predetermined conductive structure between the two components or the two positions. The electrical connection between the first fixed part 1521 and the electrical device (such as the camera module 200) can be direct electrical connection or indirect electrical connection. In the embodiments shown in FIGS. 5, 6 and 15, the first fixed part 1521 and the camera module 200 are indirectly electrically connected through the conductor 182.

[0219] The second fixed part 1531 can be used for direct electrical connection or indirect electrical connection with an external circuit board (such as a driving circuit board 180), and the folding circuit board structure 150 is used to establish electrical connection between the camera module 200 and the external circuit board, so as to realize the transmission of current and / or electrical signal. The driving circuit board 180 can be connected with the main board of the electronic device. In the embodiment shown in FIG. 4, the second fixed part 1531 is electrically connected with the driving circuit board 180.

[0220] The folding circuit board structure 150 provided by the embodiment of the present application is connected in structure and electricity between the first circuit suspension wire 152 and the second circuit suspension wire 153 through the first communication part 151, and can realize the transmission of current and / or electrical signal. When the folding circuit board structure 150 is applied to the anti-shake holder 100 or the camera device 1000, the first support 110 can rotate relative to the second support 120 around the first axis X and the second axis Y, the first fixed part 1521 in the first circuit suspension wire 152 is electrically connected with the camera module 200, and the second fixed part 1531 in the second circuit suspension wire 153 is electrically connected with the external circuit board. During the rotation of the first support 110 relative to the second support 120, the external current can be transmitted to the electric device (the camera module 200) of the first support 110 through the second circuit suspension wire 153, the first communication part 151 and the first circuit suspension wire 152, so as to realize the power supply to the electric device. The electrical signal of the camera module 200 can be transmitted to the outside through the first circuit suspension wire 152, the first communication part 151 and the second circuit suspension wire 153. The first flexible part 1522 in the first circuit suspension wire 152 extends at least partially along the third axis Z in a bending manner, the second flexible part 1532 in the second circuit suspension wire 153 extends at least partially along the third axis Z in a bending manner, so as to realize the flexible deformation of the first circuit suspension wire 152 and the second circuit suspension wire 153. The folding circuit board structure 150 has a small size in the direction of the first axis X and the second axis Y, so as to realize the miniaturization of the anti-shake holder 100 or the camera device 1000. There is no need to arrange a large-area redundant flexible circuit board 15 beside the camera module 13 in the related art as shown in FIG. 1 to realize the flexible deformation.

[0221] When the folding circuit board structure 150 is applied to the anti-shake holder 100, in combination with FIGS. 4, 15 to 17, the anti-shake holder 100 includes the first support 110, the second support 120, the intermediate support 130, the first anti-shake motor 140 and the folding circuit board structure 150. The first communication part 151 of the folding circuit board structure 150 is fixed on the intermediate support 130, the first fixed part 1521 of the first circuit suspension wire 152 is fixed on the first support 110, and the second fixed part 1531 of the second circuit suspension wire 153 is fixed on the second support 120.

[0222] During the rotation of the first support 110 relative to the second support 120 around the first axis X and the second axis Y, the first communication part 151 is kept on the intermediate support 130, the first fixed part 1521 is kept on the first support 110, and the second fixed part 1531 is kept on the second support 120, so as to allow the first flexible part 1522 and the second flexible part 1532 to deform flexibly. Moreover, the folding circuit board structure 150 can establish reliable electrical connection between the external circuit board and the electric device (such as the camera module 200) on the first support 110, so as to realize the transmission of current and / or electrical signal.

[0223] In the case that the first anti-shake coil 1412 and the second anti-shake coil 1422 of the first anti-shake motor 140 are arranged on the first support 110, the external current is transmitted to the first anti-shake coil 1412 and the second anti-shake coil 1422 through the folded circuit board structure 150. The first anti-shake coil 1412 and the second anti-shake coil 1422 arranged on the first support 110 are also the electric devices on the first support 110.

[0224] For example, the first fixed part 1521 in the first line suspension wire 152 is connected with a predetermined conductive structure (such as a wire), a part of the conductive structure is in conductive connection with the first anti-shake coil 1412, and another part of the conductive structure is in conductive connection with the second anti-shake coil 1422. The external current is transmitted to the first anti-shake coil 1412 and the second anti-shake coil 1422 through the second line suspension wire 153, the first communication part 151, the first line suspension wire 152, and the predetermined conductive structure, so as to drive the first anti-shake motor 140 to work.

[0225] For example, the folded circuit board structure 150 further includes a plurality of connection arms in conductive connection with the first communication part 151, wherein at least one connection arm is in conductive connection with the first anti-shake coil 1412, and another at least one connection arm is in conductive connection with the second anti-shake coil 1422. The external current is transmitted to the first anti-shake coil 1412 and the second anti-shake coil 1422 through the second line suspension wire 153, the first communication part 151, and the connection arms, so as to drive the first anti-shake motor 140 to work. The connection arms can be flexible suspension wires in a folded form, and the connection arms have conductive traces through which the second line suspension wire 153, the first communication part 151, and the connection arms are in conduction.

[0226] Referring to FIGS. 5, 7-9, in the case that the intermediate support 130 includes a body part 131, a first extension arm 132, and a second extension arm 133, one end of the first extension arm 132 is connected to the body part 131, and the other end of the first extension arm 132 is hinged to the first support 110, and the hinged axis of the first extension arm 132 serves as a first axis X of rotation of the first support 110 relative to the second support 120. One end of the second extension arm 133 is connected to the body part 131, and the other end of the second extension arm 133 is hinged to the second support 120, and the hinged axis of the second extension arm 133 serves as a second axis Y of rotation of the first support 110 relative to the second support 120. In combination with FIG. 15, the first communication part 151 is fixed to the body part 131 and is allowed to move with the body part 131 during the rotation of the first support 110 relative to the second support 120.

[0227] The first communication part 151 and the body part 131 are shaped to be stacked together, and the first communication part 151 is stably connected to the body part 131. For example, the first communication part 151 and the body part 131 can both be ring-shaped. Alternatively, the first communication part 151 and the body part 131 can have other same shapes. The first communication part 151 and the body part 131 can be fixed by adhesion or other methods.

[0228] In some embodiments, the first communication part 151 can be arranged on the reference plane, and the first axis X and the second axis Y are parallel to the reference plane. Arranging the first communication part 151 on the reference plane can make the structure compact, and facilitate the molding and assembly of the first communication part 151.

[0229] In some embodiments, the first communication part 151 can be arranged on the reference plane, and the first axis X and the second axis Y are parallel to the reference plane. Arranging the first communication part 151 on the reference plane can make the structure compact, and facilitate the molding and assembly of the first communication part 151.

[0230] In some embodiments, the first communication part 151 can be arranged on the reference plane, and the first axis X and the second axis Y are parallel to the reference plane. Arranging the first communication part 151 on the reference plane can make the structure compact, and facilitate the molding and assembly of the first communication part 151.

[0231] In some embodiments, the first communication part 151 can be arranged on the reference plane, and the first axis X and the second axis Y are parallel to the reference plane. Arranging the first communication part 151 on the reference plane can make the structure compact, and facilitate the molding and assembly of the first communication part 151.

[0232] In some embodiments, the first communication part 151 can be arranged on the reference plane, and the first axis X and the second axis Y are parallel to the reference plane. Arranging the first communication part 151 on the reference plane can make the structure compact, and facilitate the molding and assembly of the first communication part 151.

[0233] In some embodiments, the first communication part 151 can be arranged on the reference plane, and the first axis X and the second axis Y are parallel to the reference plane. Arranging the first communication part 151 on the reference plane can make the structure compact, and facilitate the molding and assembly of the first communication part 151.

[0234] In some embodiments, the first communication part 151 can be arranged on the reference plane, and the first axis X and the second axis Y are parallel to the reference plane. Arranging the first communication part 151 on the reference plane can make the structure compact, and facilitate the molding and assembly of the first communication part 151. In some embodiments, the first communication part 151 can be arranged on the reference plane, and the first axis X and the second axis Y are parallel to the reference plane. Arranging the first communication part 151 on the reference plane can make the structure compact, and facilitate the molding and assembly of the first communication part 151.

[0235] Compared with the prior art shown in FIG. 1, the first communication part 151, the first line suspension 152 and the second line suspension 153 are limited in the range of the second support 120 in the embodiment shown in FIG. 4, which can reduce the space occupied by the first communication part 151, the first line suspension 152 and the second line suspension 153, make the anti-shake holder 100 or the camera device 1000 compact in structure, and form reliable electrical connection between the anti-shake holder 100 and the camera module 200.

[0236] When the first line suspension 152 and the second line suspension 153 are arranged, the number of the first line suspension 152 is at least one, and the number of the second line suspension 153 is at least one. By a predetermined number of line suspensions, a predetermined number of conductive traces can be arranged.

[0237] For example, referring to (a) and (b) in FIG. 14, the first line suspension 152 is arranged in pairs, and the second line suspension 153 is arranged in pairs. The first line suspension 152 and the second line suspension 153 are both arranged in pairs on the first communication part 151, and more conductive traces can be arranged on the folded circuit board structure 150 to realize the transmission of multiple current and / or electrical signals, and to supply power or feedback electrical signals to more positions, thereby improving the reliability of the circuit.

[0238] For example, referring to (a) and (b) in FIG. 18, the number of the first line suspension 152 and the second line suspension 153 is one, and the first line suspension 152 and the second line suspension 153 are connected to the first communication part 151.

[0239] In some embodiments, referring to FIG. 15 and FIG. 16, the folded circuit board structure 150 includes the first communication part 151, the first line suspension 152 and the second line suspension 153. The intermediate support 130 includes a body part 131, a first extension arm 132 and a second extension arm 133. The first extension arm 132 is hinged to the first support 110, and the hinge axis of the first extension arm 132 serves as a first axis X of rotation of the first support 110 relative to the second support 120. The second extension arm 133 is hinged to the second support 120, and the hinge axis of the second extension arm 133 serves as a second axis Y of rotation of the first support 110 relative to the second support 120. The first line suspension 152 is arranged adjacent to the first extension arm 132, and the second line suspension 153 is arranged adjacent to the second extension arm 133.

[0240] The corresponding adjacent arrangement of different line suspensions in the folded circuit board structure 150 and different extension arms of the intermediate support 130 is beneficial to the stress decoupling of different line suspensions when the first support 110 rotates relative to the second support 120 about the first axis X and the second axis Y, and the stress states of the first line suspension 152 and the second line suspension 153 do not affect each other.

[0241] When the first support 110 rotates relative to the second support 120 around the first axis X, the intermediate support 130 does not follow the first support 110 to rotate around the first axis X, the first wire suspension 152 adjacent to the first extension arm 132 is flexibly deformed, and the second wire suspension 153 adjacent to the second extension arm 133 is not deformed or has a small deformation. When the first support 110 rotates relative to the second support 120 around the second axis Y, the intermediate support 130 follows the first support 110 to rotate around the second axis Y, the second wire suspension 153 adjacent to the second extension arm 133 is flexibly deformed, and the first wire suspension 152 adjacent to the first extension arm 132 is not deformed or has a small deformation.

[0242] Figures 10(a) to (f) are simulation diagrams of the first support 110 in the anti-shake holder 100 rotating relative to the second support 120 around the first axis X to a plurality of positions, respectively. As can be seen from Figures 10(a) to (f), during the rotation of the first support 110 relative to the second support 120 around the first axis X, the first wire suspension 152 has a change from gray to white, indicating that the first wire suspension 152 is flexibly deformed. The second wire suspension 153 remains gray, indicating that the second wire suspension 153 is not deformed or has a small deformation.

[0243] Figures 11(a) to (f) are simulation diagrams of the first support 110 in the anti-shake holder 100 rotating relative to the second support 120 around the second axis Y to a plurality of positions, respectively. As can be seen from Figures 11(a) to (f), during the rotation of the first support 110 relative to the second support 120 around the second axis Y, the second wire suspension 153 has a change from gray to white, indicating that the second wire suspension 153 is flexibly deformed. The first wire suspension 152 remains gray, indicating that the first wire suspension 152 is not deformed or has a small deformation.

[0244] This can reduce the resistance torque of the first support 110 during rotation, which is conducive to reducing the required driving torque, so that the first anti-shake motor 140 can drive the camera module 200 to rotate for anti-shake by a large angle, and the optical anti-shake effect is good.

[0245] In some embodiments, referring to Figures 14(b) and 16, the angle between the length direction of the first connecting portion 1523 of the first wire suspension 152 and the first axis X is in the range of [0°, 90°] in the vertical plane of the third axis Z. The relative position of the first wire suspension 152 and the first axis X is thus limited. When the first support 110 rotates relative to the second support 120 around the first axis X, the first wire suspension 152 is flexibly deformed to a small extent, and the resistance torque generated by the first wire suspension 152 is small.

[0246] For example, referring to FIG. 14, the length direction of the first connecting portion 1523 is parallel to or coincides with the first axis X. In addition, the length direction of the first connecting portion 1523 can also form a predetermined angle with the first axis X. In the embodiment shown in FIG. 19, the length direction of the first connecting portion 1523 forms a 90° angle with the first axis X.

[0247] In some embodiments, referring to (b) in FIG. 14 and FIG. 17, the angle between the length direction of the second connecting portion 1533 of the second circuit suspension wire 153 and the second axis Y is in the range of [0°, 90°] in the vertical plane of the third axis Z. Thus, the relative position of the second circuit suspension wire 153 and the second axis Y is defined. When the first support 110 rotates relative to the second support 120 about the second axis Y, the second circuit suspension wire 153 deforms less flexibly, and the second circuit suspension wire 153 generates a smaller resistance torque, which is conducive to reducing the required driving torque.

[0248] For example, the length direction of the second connecting portion 1533 is parallel to or coincides with the second axis Y. In addition, the length direction of the second connecting portion 1533 can also form a predetermined angle with the second axis Y.

[0249] When the first flexible portion 1522 is provided, referring to (a) in FIG. 14, the first flexible portion 1522 can include a plurality of first sub-segments 1522a connected in sequence, wherein at least one first sub-segment 1522a extends in the direction of the third axis Z. In addition, at least one first sub-segment 1522a extends in the direction of the first axis X, extends in the direction of the second axis Y, extends in a straight line, extends in an arc line, or extends in a spiral line.

[0250] The plurality of first sub-segments 1522a of the first flexible portion 1522 can be provided in a predetermined shape as needed, so as to realize the diversification of the first flexible portion 1522. When the folded circuit board structure 150 is applied to the anti-shake holder 100 or the camera device 1000, the plurality of first sub-segments 1522a of the first flexible portion 1522 can deform flexibly, so as to reduce the resistance torque suffered by the first support 110 when rotating.

[0251] In the case that the first sub-segment 1522a extends in the direction of the third axis Z (or the direction of the first axis X or the direction of the second axis Y), the center lines of the plurality of bending segments in the first sub-segment 1522a can be parallel to the third axis Z (or the first axis X or the second axis Y), or the center lines of the plurality of bending segments in the first sub-segment 1522a can form an acute angle with the third axis Z (or the first axis X or the second axis Y), so that the opposite ends of the first sub-segment 1522a are located on different vertical planes of the third axis Z (or the first axis X or the second axis Y), respectively.

[0252] In the case that the first sub-section 1522a extends along a straight line, the first sub-section 1522a can extend along any direction in a straight line. In the case that the first sub-section 1522a extends along an arc, the first sub-section 1522a can extend along any direction in a circular arc, an elliptical arc, or the like. In the case that the first sub-section 1522a extends along a spiral line, the first sub-section 1522a can extend along any direction in a spiral line.

[0253] For example, referring to (a) of FIG. 14, the first flexible part 1522 includes three first sub-sections 1522a connected in sequence, and the shapes of the three first sub-sections 1522a are respectively a bent extension along the third axis Z, a straight-line extension along the third axis Z, and a bent extension along the third axis Z, in the direction from the first connecting part 1523 to the third connecting part 1573.

[0254] For example, referring to FIG. 20, the first flexible part 1522 includes three first sub-sections 1522a connected in sequence, and the shapes of the three first sub-sections 1522a are respectively a bent extension along the third axis Z, a straight-line extension along the third axis Z, and a bent extension along the second axis Y, in the direction from the first connecting part 1523 to the third connecting part 1573.

[0255] For example, referring to FIG. 21, the first flexible part 1522 includes three first sub-sections 1522a connected in sequence, and the shapes of the three first sub-sections 1522a are respectively a bent extension along the second axis Y, a straight-line extension along the third axis Z, and a bent extension along the third axis Z, in the direction from the first connecting part 1523 to the third connecting part 1573.

[0256] In the case that the second flexible part 1532 is provided, referring to (a) of FIG. 14, the second flexible part 1532 includes a plurality of second sub-sections 1532a connected in sequence, at least one of which extends along the third axis Z in a bent manner. In addition, at least one of the second sub-sections 1532a extends along the first axis X in a bent manner, extends along the second axis Y in a bent manner, extends along a straight line, extends along an arc, or extends along a spiral line.

[0257] The plurality of second sub-sections 1532a of the second flexible part 1532 can be provided in a predetermined shape as needed, so as to realize the diversification of the second flexible part 1532. In the case that the folded circuit board structure 150 is applied to the anti-shake holder 100 or the camera device 1000, the plurality of second sub-sections 1532a of the second flexible part 1532 can be deformed in a flexible manner, so as to reduce the resistance moment suffered by the first support 110 when the first support 110 rotates. The specific arrangement of the second sub-sections 1532a can refer to the embodiments of the first sub-sections 1522a described above, and will not be described herein again.

[0258] In the setting of the first connecting part 1523 and the second connecting part 1533, referring to (a) of FIG. 14 and FIG. 17, the first connecting part 1523 and the second connecting part 1533 are both connected to the side edge 151a of the first communicating part 151 away from the axis (third axis Z) of the camera module 200, and the first connecting part 1523 and the second connecting part 1533 both extend away from the axis (third axis Z) of the camera module 200.

[0259] The first connecting part 1523 is connected to the first flexible part 1522, and the second connecting part 1533 is connected to the second flexible part 1532. The first connecting part 1523 and the second connecting part 1533 are located on the side of the first communicating part 151 away from the camera module 200, so as to facilitate the arrangement of the first flexible part 1522 and the second flexible part 1532 at a position outside the axis (third axis Z) of the camera module 200 of the first support 110, i.e., in the region between the first support 110 and the second support 120. When the first support 110 rotates relative to the second support 120 about the first axis X or the second axis Y, the first flexible part 1522 or the second flexible part 1532 is allowed to deform flexibly. The first connecting part 1523 and the second connecting part 1533 can be in the shape of a strip or other shapes.

[0260] In order to reduce the moment of resistance of the rotation of the first support 110, in some embodiments, referring to (a) and (b) of FIG. 14, the first connecting part 1523 is connected to the first communicating part 151 at a position corresponding to the first axis X, and the second connecting part 1533 is connected to the first communicating part 151 at a position corresponding to the second axis Y.

[0261] The first connecting part 1523 is limited to the position corresponding to the first axis X, thereby defining the first line suspension wire 152 on the first axis X. When the first support 110 rotates about the first axis X, the first line suspension wire 152 deforms flexibly less. The second axis Y is limited to the position corresponding to the second axis Y, thereby defining the second line suspension wire 153 on the second axis Y. When the first support 110 rotates about the second axis Y, the second line suspension wire 153 deforms flexibly less. The reduction of the moment of resistance of the rotation of the first support 110 facilitates the reduction of the required driving moment, so that the first anti-shake motor 140 can drive the camera module 200 to rotate for anti-shake by a large angle, and the optical anti-shake effect is good.

[0262] In the case where the first axis X and the second axis Y are perpendicular to each other, the positions of the first connecting part 1523 and the second connecting part 1533 are orthogonally arranged with the third axis Z as the center, i.e., the first line suspension wire 152 and the second line suspension wire 153 are orthogonally arranged with the third axis Z as the center.

[0263] For example, the first pair of suspension wires 152 are arranged along the first axis X, and the second pair of suspension wires 153 are arranged along the second axis Y. The first pair of suspension wires 152 are arranged along the first axis X, and the second pair of suspension wires 153 are arranged along the second axis Y, so that the deformation of the first pair of suspension wires 152 and the second pair of suspension wires 153 can be reduced to reduce the resistance torque when the first support 110 rotates relative to the second support 120.

[0264] In other embodiments, the first connecting portion 1523 can be connected to the first connecting portion 151 at a position not corresponding to the first axis X, or the second connecting portion 1533 can be connected to the first connecting portion 151 at a position not corresponding to the second axis Y, so that the electrical connection between the outside of the anti-shake holder 100 and the camera module 200 can be maintained during the rotation of the first support 110 relative to the second support 120, and the transmission of current and / or electrical signals can be realized.

[0265] In some embodiments, referring to (a) and (b) of FIG. 14, FIG. 16, and FIG. 17, the first fixed portion 1521 of the first pair of suspension wires 152 is located on the first axis X, i.e., the first axis X passes through the first fixed portion 1521. When the first support 110 rotates relative to the second support 120 around the first axis X, the intermediate support 130 remains stationary, the first support 110 rotates relative to the first extension arm 132, the first fixed portion 1521 remains on the first support 110, the first flexible portion 1522 has small flexible deformation, and the first pair of suspension wires 152 generates small resistance torque, which is beneficial to reduce the required driving torque.

[0266] The second fixed portion 1531 of the second pair of suspension wires 153 is located on the second axis Y, i.e., the second axis Y passes through the second fixed portion 1531. When the first support 110 rotates relative to the second support 120 around the second axis Y, the second extension arm 133 rotates relative to the second support 120, the second fixed portion 1531 remains on the second support 120, the second flexible portion 1532 has small flexible deformation, and the second pair of suspension wires 153 generates small resistance torque, which is beneficial to reduce the required driving torque.

[0267] When the first fixed portion 1521 is arranged, referring to FIG. 14 and FIG. 15, the first fixed portion 1521 can be in a sheet shape, a bent shape, etc., so that the first fixed portion 1521 avoids the surrounding structures such as the first flexible portion 1522 and the first support member 134 of the intermediate support 130, and adjusts the first fixed portion 1521 to a predetermined position to realize the fixation of the first fixed portion 1521 and the first support 110 and the electrical connection with the camera module 200. The first fixed portion 1521 can be welded or fixed in other ways on the first support 110 and electrically connected with the camera module 200.

[0268] For example, referring to FIGS. 14 and 15, the first fixed part 1521 is in a sheet shape, the first fixed part 1521 is parallel to the axis (third axis Z) of the camera module 200, and the first fixed part 1521 is linearly arranged along the direction of the third axis Z. The first flexible part 1522 is arranged adjacent to the first supporting part 134 of the intermediate support 130, and the first flexible part 1522 avoids the first supporting part 134. Referring to FIG. 16, the first fixed part 1521 can be connected through a predetermined conductive structure (such as a conductor 182) and a circuit board for mounting an image sensor.

[0269] For example, the first fixed part 1521 is in a bent shape, the first fixed part 1521 avoids the first flexible part 1522 and the first supporting part 134, and the end of the first fixed part 1521 is directly connected to the circuit board for mounting the image sensor.

[0270] When the second fixed part 1531 is arranged, referring to FIGS. 4, 14 and 16, the second fixed part 1531 can be in a sheet shape, a bent shape, etc., so that the second fixed part 1531 avoids the surrounding structures such as the second flexible part 1532 and the second supporting part 135 of the intermediate support 130, and the second fixed part 1531 is adjusted to a predetermined position to realize the fixation of the second fixed part 1531 and the second support 120 and the electrical connection with an external circuit board (such as a driving circuit board 180) or other circuit boards. The second fixed part 1531 can be welded or fixed in other ways on the second support 120 and electrically connected with the external circuit board or other circuit boards.

[0271] For example, referring to FIG. 17, the second fixed part 1531 is in a sheet shape, the second fixed part 1531 is parallel to the axis (third axis Z) of the camera module 200, and the second fixed part 1531 is linearly arranged along the direction of the third axis Z. The second flexible part 1532 is arranged adjacent to the second supporting part 135 of the intermediate support 130, and the second flexible part 1532 avoids the second supporting part 135. For example, the second fixed part 1531 has a first arm and a second arm in an L-shaped distribution, one end of the first arm and one end of the second arm are connected, the first arm is linearly extended in a direction away from the axis of the camera module 200, and the second arm is linearly extended along the direction of the third axis Z. The L-shaped second fixed part 1531 is adopted, so that the second supporting part 135 of the intermediate support 130 is located in the L-shaped space of the second fixed part 1531, and the second supporting part 135 can be avoided. In the embodiment shown in FIG. 4, the second fixed part 1531 can be located on the outer surface of the second support 120, which facilitates the conductive connection (such as welding) of the second fixed part 1531 with the external circuit board 180 arranged outside the second support 120.

[0272] In another embodiment, the second fixing part 1531 can also be located on the inner surface of the second support 120, and a predetermined part of the external circuit board 180 is located on the inner surface of the second support 120, and the second fixing part 1531 and the predetermined part of the external circuit board 180 are conductively connected.

Two exemplary implementation manners of the folded circuit board structure 150 are given below.

[0274] The first implementation manner of the folded circuit board structure 150: referring to FIG. 22, the first communication part 151, the first line suspension 152 and the second line suspension 153 are all flexible boards. The flexible boards are easy to manufacture, and the first line suspension 152, the first communication part 151 and the second line suspension 153 are sequentially electrically connected through conductive traces on the flexible boards.

The first connecting part 1523 and the second connecting part 1533 can also be provided with a protective layer 151b to protect the first connecting part 1523 and the second connecting part 1533.

[0276] The second implementation manner of the folded circuit board structure 150: the folded circuit board structure 150 is a rigid-flexible combined board, the first communication part 151 is a rigid board, and the first line suspension 152 and the second line suspension 153 are both flexible boards.

[0277] The rigid-flexible combined board is a circuit board combining a rigid board and a flexible board. The first communication part 151 is provided as a rigid board, which can reduce the collision damage of the first connecting part 1523 during the movement of the first support 110. The first line suspension 152 and the second line suspension 153 are provided as flexible boards, so that the first line suspension 152 or the second line suspension 153 can be flexibly deformed during the movement of the first support 110.

[0278] In order to realize the three-axis rotation of the anti-shake holder 100 or the camera device 1000, in some embodiments, referring to FIGS. 23 to 25, on the basis of the anti-shake holder 100 including the first support 110, the second support 120, the intermediate support 130, the first anti-shake motor 140 and the folded circuit board structure 150, the anti-shake holder 100 further includes a base 160 and a second anti-shake motor 170. The second support 120 is arranged on the base 160, and the second support 120 can rotate relative to the base 160 around the third axis Z. The second anti-shake motor 170 is used to drive the second support 120 to rotate around the third axis Z.

[0279] The first support 110 is used for mounting the camera module 200, the camera module 200 can rotate with the first support 110 relative to the second support 120 around the first axis X and the second axis Y, and the camera module 200 can also rotate with the second support 120 relative to the base 160 around the third axis Z. The first anti-shake motor 140 can drive the first support 110 or the camera module 200 to rotate within a certain range around the first axis X and the second axis Y, and the second anti-shake motor 170 can drive the second support 120 to rotate within a certain range around the third axis Z, so as to make the camera module 200 do three-axis motion compensation to realize optical anti-shake in a shaking scene.

[0280] On the basis that the folding circuit board structure 150 comprises the first communication part 151, the first line suspension 152 and the second line suspension 153, in combination with FIGS. 26 to 28, the folding circuit board structure 150 further comprises a second communication part 156 and a third line suspension 157 connected in sequence, and the second communication part 156 is connected with the second line suspension 153. The second communication part 156 is fixed on the second support 120, and the third line suspension 157 is located between the base 160 and the second support 120.

[0281] When the second support 120 rotates relative to the base 160 around the third axis Z, the third line suspension 157 can be flexibly deformed relative to the base 160. The third line suspension 157 is located between the base 160 and the second support 120, and the third line suspension 157 occupies a small space, which is conducive to miniaturization of the anti-shake gimbal 100 or the camera device 1000.

[0282] In the process that the camera module 200 can rotate around the first axis X, the second axis Y and the third axis Z, the folding circuit board structure 150 can realize transmission of current and / or electrical signals between the outside of the anti-shake gimbal 100 and the camera module 200.

[0283] The external current can be transmitted from the outside to the inside through the folding circuit board structure 150 to the power-consuming device (such as the camera module 200) on the first support 110. The transmission path of the external current is: the third line suspension 157, the second communication part 156, the second line suspension 153, the first communication part 151 and the first line suspension 152, and then to the camera module 200.

[0284] The electrical signals of the image sensor 210 can be transmitted to the outside of the anti-shake gimbal 100 through the folding circuit board structure 150. The outward transmission path of the electrical signals of the image sensor 210 is: the first line suspension 152, the first communication part 151, the second line suspension 153, the second communication part 156 and the third line suspension 157, and then to the outside of the anti-shake gimbal 100.

[0285] The folded circuit board structure 150 can be a single-piece structure or an assembled structure. For example, the first connecting portion 151, the first line suspension wire 152, and the second line suspension wire 153 are a single-piece structure. The second connecting portion 156 and the third line suspension wire 157 are also a single-piece structure. The second line suspension wire 153 and the second connecting portion 156 can be connected by welding, joints, or other methods.

[0286] When setting the base 160, referring to Figures 23 and 24, the base 160 can be frame-shaped, and the second support 120 can be set inside the base 160. The bottom surface of the second support 120 and the bottom surface of the base 160 are set opposite to each other, and the second support 120 can move inside the base 160.

[0287] To facilitate the assembly of the intermediate bracket 130 between the first bracket 110 and the second bracket 120, in some embodiments, referring to FIG25, the first bracket 110 has a first mounting groove 112, and a first extension arm 132 is hinged to the first mounting groove 112 via a first support member 134, which is disposed on the first extension arm 132 and located within the first mounting groove 112. The second bracket 120 has a second mounting groove 122, and a second extension arm 133 is hinged to the second mounting groove 122 via a second support member 135, which is disposed on the second extension arm 133 and located within the second mounting groove 122.

[0288] Referring to Figures 24 and 29, the first mounting groove 112 has a first opening 1121, and a first limiting member 113 is provided at the first opening 1121. The first limiting member 113 is used to limit the first support member 134 to be located at the first mounting groove 112. The first support member 134 on the first extension arm 132 is inserted into the first mounting groove 112 through the first opening 1121, and then the first limiting member 113 is fixed at the first opening 1121, so that the first support member 134 is limited at the first mounting groove 112, which facilitates the assembly of the first support member 134 onto the first bracket 110. The first limiting member 113 can be assembled onto the first bracket 110 by means of snap-fit, adhesive, etc.

[0289] Referring to Figures 24, 25, 29, and 30, the second mounting groove 122 has a second opening 1221, and a second limiting member 123 is provided at the second opening 1221. The second limiting member 123 is used to limit the second support member 135 to be located at the second mounting groove 122. The second support member 135 on the second extension arm 133 is inserted into the second mounting groove 122 through the second opening 1221, and then the second limiting member 123 is fixed at the second opening 1221, so that the second support member 135 is limited at the second mounting groove 122, which facilitates the assembly of the second support member 135 onto the second bracket 120. The second limiting member 123 can be assembled onto the second bracket 120 by means of snap-fit, adhesive, or other methods.

[0290] In the setting of the second anti-shake motor 170, referring to FIG. 24 and FIG. 25, the second anti-shake motor 170 can be a voice coil motor, a piezoelectric motor or a shape memory alloy motor. The above anti-shake motors can all drive the second support 120 to rotate within a certain range around the third axis Z, and perform motion compensation of the camera module 200 in a shaking scene, thereby realizing optical anti-shake.

[0291] Hereinafter, the second anti-shake motor 170 is taken as an example of a voice coil motor.

[0292] Referring to FIG. 25 and FIG. 31, the second anti-shake motor 170 comprises a third magnetic assembly 170a, which comprises a third anti-shake magnetic piece 171 and a third anti-shake coil 172. One of the third anti-shake magnetic piece 171 and the third anti-shake coil 172 is arranged on the second support 120, and the other is arranged on the base 160. The third anti-shake magnetic piece 171 and the third anti-shake coil 172 cooperate to drive the second support 120 to rotate around the third axis Z.

[0293] The third anti-shake magnetic piece 171 and the third anti-shake coil 172 in the third magnetic assembly 170a are arranged in a spaced-apart manner. The center of the third anti-shake magnetic piece 171 and the center of the third anti-shake coil 172 are both arranged in a spaced-apart manner with respect to the third axis Z. The energized third anti-shake coil 172 is subjected to a third Lorentz magnetic force in the magnetic field of the third anti-shake magnetic piece 171, and can generate a third torque for driving the second support 120 to rotate around the third axis Z with respect to the base 160. By changing the current direction of the third anti-shake coil 172, the direction of the third Lorentz force can be changed to generate third torques in different directions. The number of the third magnetic assemblies 170a is at least one. By changing the number of the third magnetic assemblies 170a or changing the input current of the third anti-shake coil 172, the driving torque of the second support 120 can be changed.

[0294] For example, three sets of third magnetic assemblies 170a are arranged on the second support 120 and the base 160, and the three sets of third magnetic assemblies 170a are arranged in a ring around the axis (third axis Z) of the camera module 200.

[0295] For example, one set of third magnetic assemblies 170a is arranged on the second support 120 and the base 160, and the third magnetic assembly 170a is arranged in a spaced-apart manner with respect to the axis (third axis Z) of the camera module 200.

[0296] In order to reduce the frictional force of the movement of the second support 120 with respect to the base 160, in some embodiments, referring to FIG. 31, a support portion 161 is arranged between the bottom surfaces of the base 160 and the second support 120 in the direction of the third axis Z.

[0297] During the movement of the second support 120 relative to the base 160, the support portions 161 are located between the second support 120 and the base 160, which improves the stability of the movement of the second support 120 relative to the base 160. The support portions 161 can be protruding portions with smooth contact surfaces or balls, and the support portions 161 can be arranged on the second support 120 or the base 160. The friction between the second support 120 and the base 160 during the movement is small, which reduces the driving power consumption.

[0298] For example, three support portions 161 are arranged between the base 160 and the bottom surface of the second support 120, and the three support portions 161 form three point surface contact positions distributed around the axis of the camera module 200, so that the second support 120 can stably move relative to the base 160 and the shaking of the second support 120 during the movement is reduced.

[0299] In order to limit the second support 120 on the base 160, in some embodiments, referring to FIG. 31, the base 160 is provided with a third limiting member 162 for limiting the second support 120 on the base 160 along the third axis Z.

[0300] The third limiting member 162 can make the second support 120 and the base 160 have a tendency to approach each other, so that the second support 120 can stably move relative to the base 160, and the movement stability of the second support 120 is improved.

[0301] In the case where the support portions 161 are arranged between the base 160 and the bottom surface of the second support 120 along the third axis Z, the third limiting member 162 can keep the plurality of support portions 161 arranged between the second support 120 and the base 160, so that the second support 120 can stably move relative to the base 160.

[0302] For example, referring to FIG. 31, the second anti-shake motor 170 is a voice coil motor, the third anti-shake magnetic member 171 in the third magnetic assembly 170a is arranged on the second support 120, and the third limiting member 162 can be a magnetic conducting member (such as a steel sheet) arranged on the base 160. The magnetic conducting member and the third anti-shake magnetic member 171 are arranged opposite to each other and magnetically adsorbed, so that the second support 120 is pressed on the base 160 along the third axis Z.

[0303] For example, the third limiting member 162 can be a spring arranged on the base 160, and the free end of the spring abuts against the second support 120, so that the second support 120 is limited on the base 160 and cannot be separated from the base 160.

[0304] In order to realize the transmission of current / electric signal in the three-axis rotating anti-shake holder 100 or the camera device 1000, in some embodiments, referring to FIGS. 24-26, on the basis of the folding circuit board structure 150 including the first communication part 151, the first line suspension 152 and the second line suspension 153, the folding circuit board structure 150 further includes a second communication part 156 and one or more third line suspensions 157. The second communication part 156 is connected with the second line suspension 153. The third line suspension 157 includes a third fixed part 1571, a third flexible part 1572 and a third connecting part 1573 connected in sequence, the third flexible part 1572 is at least partially bent and extended along the vertical direction of the third axis Z, and the third connecting part 1573 is connected with the second communication part 156. In combination with FIGS. 27 and 28, the third line suspension 157 and the second line suspension 153 are electrically connected through the second communication part 156.

[0305] In the above embodiment, the second communication part 156 and the third line suspension 157 both have conductive traces, so that the third line suspension 157 and the second line suspension 153 are electrically connected through the second communication part 156, thereby realizing the transmission of current and / or electric signal.

[0306] The third line suspension 157 is divided into the third fixed part 1571, the third flexible part 1572 and the third connecting part 1573 for the convenience of describing the structure and function of each part. The third fixed part 1571, the third flexible part 1572 and the third connecting part 1573 can be an integral structure.

[0307] The third flexible part 1572 is at least partially bent and extended along the vertical direction of the third axis Z, which can be that a part of the third flexible part 1572 is bent and extended along the vertical direction of the third axis Z, or that the whole third flexible part 1572 is bent and extended along the vertical direction of the third axis Z. The vertical direction of the third axis Z is any direction in the plane of the first axis X and the second axis Y, such as the parallel direction of the first axis X, the parallel direction of the second axis Y, etc.

[0308] The folding circuit board structure 150 is applied to the three-axis rotation anti-shake holder 100 or the camera device 1000, the first support 110 can rotate relative to the second support 120 around the first axis X and the second axis Y, the second support 120 can rotate relative to the base 160 around the third axis Z, the third fixed part 1571 in the third line suspension wire 157 is fixed with the base 160 and electrically connected with the external circuit board. In the process of rotating the camera module 200 around the first axis X, the second axis Y or the third axis Z, the external current can be transmitted to the camera module 200 through the third line suspension wire 157, the second communication part 156, the second line suspension wire 153, the first communication part 151 and the first line suspension wire 152, and power supply to the camera module 200 is realized. The electrical signal of the image sensor 210 can be transmitted to the outside of the anti-shake holder 100 through the first line suspension wire 152, the first communication part 151, the second line suspension wire 153, the second communication part 156 and the third line suspension wire 157. When the second support 120 rotates relative to the base 160 around the third axis Z, the third line suspension wire 157 is flexibly deformed.

[0309] When the second communication part 156 is arranged, referring to FIGS. 26 and 28, the second communication part 156 can be arranged along the outer side surface of the second support 120. The second communication part 156 can be arranged in a straight line, a curve or a plurality of lines along the outer side surface of the second support 120, or can be arranged in a ring shape along the outer side surface of the second support 120.

[0310] When the third flexible part 1572 is arranged, referring to FIGS. 26 and 32, the third flexible part 1572 can be bent and arranged along the first axis X or the second axis Y between the second support 120 and the base 160, and the third flexible part 1572 can be flexibly deformed and occupies a small space.

[0311] In order to arrange more conductive traces on the folding circuit board structure 150, in some embodiments, referring to FIGS. 26 and 28, pairs of third line suspension wires 157 are arranged at intervals and connected with the second communication part 156. Arranging more conductive traces on the folding circuit board structure 150 can realize the transmission of multiple currents and / or electrical signals, can supply power or feedback electrical signals to more positions, and can improve the reliability of the circuit.

[0312] When detecting the rotation position of the first support 110 relative to the second support 120 around the first axis X, there are various optional implementation manners. Two optional implementation manners are exemplarily given below.

[0313] The first method for detecting the rotational position of the first support 110 relative to the second support 120 around the first axis X is as follows: Referring to Figures 33(a) and (b), a first mounting portion 154 is connected to the first connecting portion 151 near the first axis X, and a first position sensor 154a is provided on the first mounting portion 154; referring to Figure 29, a first detection magnet 154b is provided on the first support 110, and the first detection magnet 154b and the first position sensor 154a are arranged facing each other. The first detection magnet 154b and the first position sensor 154a cooperate to detect the rotational position of the first support 110 around the first axis X. The first mounting portion 154 extends at least partially along the direction of the third axis Z, and the first position sensor 154a is provided on the portion of the first mounting portion 154 that extends along the direction of the third axis Z.

[0314] During the rotation of the first support 110 relative to the second support 120 around the first axis X driven by the first anti-shake motor 140, the intermediate support 130 does not rotate with the first support 110. The intermediate support 130 and the first position sensor 154a are stationary components, while the first detection magnet 154b is a moving component that rotates with the first support 110 around the first axis X. The first position sensor 154a can detect the change in the magnetic field of the first detection magnet 154b, and thus determine the rotational position of the first support 110 around the first axis X.

[0315] The first position sensor 154a can be a Hall sensor, a magnetoresistive sensor, etc. The first detection magnet 154b can extend along the direction of the third axis Z. The first position sensor 154a and the first detection magnet 154b can be disposed between the first bracket 110 and the second bracket 120, and need to avoid the first line suspension wire 152.

[0316] Referring to Figures 25 and 27, the first mounting portion 154 can be a flexible plate, and the intermediate bracket 130 has a first support arm 136 connected to the main body portion 131. The flexible first mounting portion 154 can be fixed on the first support arm 136. Alternatively, the first mounting portion 154 can also be a rigid plate.

[0317] The second implementation of the rotation position detection of the first support 110 relative to the second support 120 around the first axis X is described with reference to (a) and (b) of FIG. 33. The first communication portion 151 is connected with a second mounting portion 155 near the second axis Y, and the second mounting portion 155 is provided with a second position sensor 155a. In combination with FIG. 24, the first support 110 is provided with a second detection magnet 155b, and the second detection magnet 155b and the second position sensor 155a are arranged to face each other. The second detection magnet 155b and the second position sensor 155a cooperate to detect the rotation position of the first support 110 around the first axis X. The second mounting portion 155 extends at least partially along the third axis Z, and the second position sensor 155a is arranged on the portion of the second mounting portion 155 extending along the third axis Z.

[0318] During the driving of the first support 110 relative to the second support 120 around the first axis X by the first anti-shake motor 140, the intermediate support 130 does not rotate with the first support 110, and the intermediate support 130 and the second position sensor 155a are stationary components, and the second detection magnet 155b is a movable component and rotates with the first support 110 around the first axis X. The second position sensor 155a can detect the magnetic field change of the second detection magnet 155b, and the rotation position of the first support 110 around the first axis X can be obtained.

[0319] The second position sensor 155a can be a Hall sensor, a magnetoresistance sensor, etc. The second detection magnet 155b can extend along the third axis Z. The second position sensor 155a and the second detection magnet 155b can be arranged between the first support 110 and the second support 120, and need to avoid the second wire suspension 153.

[0320] Referring to FIG. 25, the second mounting portion 155 can be a flexible plate, and the intermediate support 130 has a second support arm 137 connected with the body portion 131. The flexible second mounting portion 155 can be fixed on the second support arm 137. Alternatively, the second mounting portion 155 can also be a rigid plate.

[0321] It can be understood that the above two implementation modes of the rotation position detection of the first support 110 relative to the second support 120 around the first axis X can be selected, or both of the two implementation modes can be used.
