Description

[Technical field]

[0001] The present application is in the technical field of cameras, and more particularly, to camera structures and electronics. [Background technology]

[0002] With the development of electronic devices, people have higher and higher requirements for the shooting performance of electronic devices, and the application of micro gimbals in electronic devices can greatly improve the image quality experience of consumers when shooting handheld. The amount of shaking corresponding to hand shake can generally be decomposed into three directions of X, Y, and Z in space, and there are a total of six degrees of freedom (movement along the three axes of X / Y / Z and rotations Rx, Ry, and Rz around the three axes of X / Y / Z). Among them, except for the axial shake in the focus direction (Z axis), the other five degrees of freedom all have a significant impact on handheld shooting, especially night shooting and video shooting, and ultimately affect the shooting effect and consumer experience. The micro gimbal camera used in current electronic devices (e.g., mobile phones) is based on a two-axis gimbal, which can only correct shakes in four degrees of freedom and cannot correct the shake (Rz) caused by rotation around the Z axis, so when shake in the Rz direction occurs, the image quality of the micro gimbal camera is reduced.

It should be understood that the terms used in this manner may be substituted for each other where appropriate, so that the embodiments of the present application may be performed in an order other than that shown or described herein, and that the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited, for example, the first object may be one or more.

[0026] The camera structure and electronic device provided in the embodiments of the present application will be described in detail below with reference to the drawings according to specific embodiments and their application scenarios.

[0027] Please refer to FIG. 1 to FIG. 3d, in which FIG. 1 is a structural diagram of a camera structure provided in an embodiment of the present application. FIG. 2 is an exploded view of a camera structure provided in an embodiment of the present application. FIG. 3a is a top view of a camera structure provided in an embodiment of the present application. FIG. 3b is a cross-sectional view in the AA direction of FIG. 3a. FIG. 3c is a cross-sectional view in the BB direction of FIG. 3a. FIG. 3d is a bottom view of a camera structure provided in an embodiment of the present application. The camera structure provided in the embodiment of the present application includes a universal shaft 2, a gimbal outer support 9 and an intra-gimbal support 5 housed in the gimbal outer support 9, a gimbal carrier 10, a first driving mechanism 101, a second driving mechanism 102, and a camera module 103.

[0028] Wherein, the camera module 103 is movably connected to the gimbal outer support 9, and the camera module 103 is fixedly connected to the gimbal carrier 10. The universal shaft 2 has two supports 25 distributed in the axial direction of a first axis that are hingedly connected to the gimbal outer support 9, and the universal shaft 2 has two supports 25 distributed in the axial direction of a second axis that are hingedly connected to the gimbal inner support 5, where the first axis and the second axis intersect. The first driving mechanism 101 is connected to the gimbal outer support 9 and the gimbal inner support 5, respectively, for driving the gimbal inner support 5 to rotate about the first axis and / or the second axis relative to the gimbal outer support 9.

[0029] Also, the gimbal carrier 10 is slidably connected to the bottom of the intra-gimbal support 5. A second drive mechanism 102 is connected to the intra-gimbal support 5 and the gimbal carrier 10, respectively, for driving the gimbal carrier 10 to rotate relative to the intra-gimbal support 5 about a third axis, where the third axis is perpendicular to the first axis and the second axis, respectively.

[0030] In a specific implementation, the first axis may extend in the same direction as line H shown in Fig. 1, the second axis may extend in the same direction as line M shown in Fig. 1, and the third axis may be the Z axis shown in Fig. 1. Of course, in practice, the first axis and the second axis do not need to be perpendicular to each other, for example, the included angle between the first axis and the second axis is greater than 0° and less than 180°.

[0031] In practice, driving the intra-gimbal support 5 to rotate around the first axis and / or the second axis relative to the gimbal outer support 9 may be interpreted as driving the intra-gimbal support 5 to rotate around the X-axis or the Y-axis relative to the gimbal outer support 9, where the gimbal outer support 9 may have a rectangular structure, and the X-axis and Y-axis are respectively parallel to two mutually perpendicular rectangular sides of the gimbal outer support 9.

[0032] Specifically, the intra-gimbal support 5 has rotation components along the X-axis and Y-axis directions in the process of rotating about the first axis relative to the gimbal outer support 9. Similarly, the intra-gimbal support 5 also has rotation components along the X-axis and Y-axis directions in the process of rotating about the second axis relative to the gimbal outer support 9. In this case, if it is necessary to drive the rotation of the intra-gimbal support 5 only about the X-axis relative to the gimbal outer support 9, it is possible to realize driving of the rotation of the intra-gimbal support 5 about the X-axis relative to the gimbal outer support 9 by canceling out the component along the Y-axis direction in the process of rotating the intra-gimbal support 5 about the first axis relative to the gimbal outer support 9 and the component along the Y-axis direction in the process of rotating the intra-gimbal support 5 about the second axis relative to the gimbal outer support 9.

[0033] The above-mentioned camera module 103 being fixedly connected to the gimbal carrier 10 may be understood as the outer wall of the camera module 103 being bonded to the inner wall of the gimbal carrier 10 and fixedly connected thereto.

[0034] In practice, as shown in Figures 1 and 2, the camera structure provided in the embodiment of the present application may include a case 1, which may include a top case 1a and a bottom case 1b. The bottom case 1b is recessed away from the top case 1a to form an accommodation space between the top case 1a and the bottom case 1b, and the universal shaft 2, the gimbal outer support 9, the gimbal inner support 5 accommodated in the gimbal outer support 9, the gimbal carrier 10, the first driving mechanism 101, the second driving mechanism 102, and the camera module 103 can be accommodated in the accommodation space of the case 1. In addition, the top case 1a, the universal shaft 2, the gimbal outer support 9, the gimbal inner support 5, and the gimbal carrier 10 are all provided with light passing holes, so that the lowest camera module 103 collects image information through the light passing holes, and thus the head part of the camera module 103 (i.e., the upper part along the Z axis in Figure 1) is exposed to the top case 1a through the light passing holes.

[0035] In this way, the camera structure provided in the embodiment of the present application can be sealed as a whole by the case 1, and the case 1 can also protect the camera module 103 and the like therein.

[0036] In a specific implementation, the first drive mechanism 101 and the second drive mechanism 102 may each be a motor drive mechanism, an electromagnetic drive mechanism, etc., and for convenience of explanation, the following embodiments will be described simply by giving an example in which the first drive mechanism 101 and the second drive mechanism 102 are electromagnetic drive mechanisms, and no specific limitations are made here.

[0037] Among the coordinate axes shown in FIG. 1, Rx, Ry, and Rz represent the directions of rotation around the X-axis, Y-axis, and Z-axis, respectively.

[0038] In the embodiment of the present application, the second driving mechanism independently drives the gimbal carrier to rotate in the Rz axis direction to realize shake compensation for the Rz axis, so that the Rz axis shake compensation system is independent of the Rx and Ry shake compensation systems. In this way, when the image stabilization function is performed in the Rx and Ry axis directions, the Rz position feedback system is not affected, so that the accuracy of the Rz axis shake compensation is effectively improved, and even if camera shake occurs during night photography or video shooting, the shooting image quality is effectively improved, and the consumer experience is further improved.

[0039] The above-mentioned universal shaft 2 has two support parts 25 distributed in the axial direction of the first axis that are hinged to the gimbal outer support 9, and two support parts 25 distributed in the axial direction of the second axis that are hinged to the gimbal inner support 5, which may be interpreted as follows: The two support parts 25 distributed in the axial direction of the first axis of the universal shaft 2 constitute a first rotation axis, and when these two support parts 25 are hinged to the gimbal outer support 9, the universal shaft 2 can rotate about the first rotation axis relative to the gimbal outer support 9, and the two support parts 25 distributed in the axial direction of the second axis of the universal shaft 2 constitute a second rotation axis, and when these two support parts 25 are hinged to the gimbal outer support 5, the universal shaft 2 can rotate about the second rotation axis relative to the gimbal outer support 5, and the gimbal inner support 5 can rotate about the first rotation axis and the second rotation axis, respectively, relative to the gimbal outer support 9.

[0040] Based on this, the camera module 103 can be rotated in the RZ axis direction relative to the gimbal in-support 5 by the gimbal carrier 10. Therefore, the camera module 103 can rotate in the Rx, Ry, and Rz axis directions. In actual shooting, shake parameters such as the camera shake direction and shake distance can be obtained, and based on this, the camera structure provided in the embodiment of the present application can be controlled to rotate in the Rx, Ry, and Rz directions by the corresponding rotation amounts, thereby realizing image stabilization along the Rx, Ry, and Rz axis directions.

[0041] Optionally, as shown in FIG. 6a, a first accommodating space 905 is provided between a first inner wall of the gimbal outer support 9 and a first outer wall of the gimbal inner support 5, and the first driving mechanism 101 and the second driving mechanism 102 are arranged in the first accommodating space 905.

[0042] In a specific implementation, the head portion of the camera module 103 can extend outside the gimbal outer support 9 through a light passing hole on the upper side of the gimbal outer support 9; that is, the first driving mechanism 101 and the second driving mechanism 102 can be aligned with the tail portion of the camera module 103 (i.e., downward along the Z axis in FIG. 1); in this way, the electromagnetic driving modules in the first driving mechanism 101 and the second driving mechanism 102 can be arranged in an area away from the head portion of the gimbal, leaving more non-magnetic area in the head portion of the gimbal, and increasing the types of selectable driving motors for the camera module mounted on the gimbal; for example, an Optical Image Stabilization (OIS) camera module can be selected and mounted. In this way, by incorporating the image stabilization functions along the Rx, Ry, and Rz directions of the camera structure provided in the embodiments of the present application, a camera system with 5-axis image stabilization (i.e., image stabilization along the X, Y, Rx, Ry, and Rz directions, respectively) can be constructed, and the camera system can be driven respectively to compensate for the shake of the 5 degrees of freedom individually or jointly, thereby avoiding the influence of the time lag and the compensation state that cannot be switched in a timely manner that exists in the motion compensation synthesis, improving the quality of the captured images and videos, especially the shooting quality when camera shake occurs during night shooting can be more effectively improved, and the overall usage experience of consumers can be improved.

[0043] Optionally, as shown in FIG. 2 and FIG. 3b, the first driving mechanism 101 includes a first yoke 22, a first driving coil group 7, and a first magnet group 21; The first driving coil group 7 is fixed to the gimbal outer support 9, the first yoke 22 is fixed to the first outer wall of the gimbal inner support 5, the first magnet group 21 is fixed to the first yoke 22, and the first magnet group 7 and the first driving coil group 7 are fitted to each other; At least two coils in the first drive coil group 7 are spaced apart in a first direction, the first direction being perpendicular to the third axis (z-axis), and the first drive coil group 7 is distributed on opposite sides of an axis of symmetry of the gimbal intra-support 5, the axis of symmetry being the same direction as the direction from the first outer wall of the gimbal intra-support 5 to the first inner wall of the gimbal extra-support 9; Here, when current is passed through the first drive coil group 7, an interaction force is generated between the first drive coil group 7 and the first magnet group 21, and the first magnet group 21 drives the gimbal intra-support 5 to rotate around the first axis and / or the second axis relative to the gimbal outer support 9 based on the interaction force (it may also be interpreted that the first drive coil group 7 drives the gimbal intra-support 5 to rotate around the first axis and / or the second axis relative to the gimbal outer support 9 based on the interaction force).

[0044] In a specific implementation, the first direction may be the same direction as the Y-axis shown in Figure 1, and the first magnet group 21 and the first drive coil group 7 being arranged in a compatible manner may be interpreted as meaning that the magnetic field generated by the first drive coil group 7 can act on the first magnet group 21 and a magnetic circuit is generated between the first yoke 22 and the first magnet group 21, or that the magnets in the first magnet group 21 and the coils in the first drive coil group 7 are arranged in one-to-one correspondence, and the corresponding magnets and coils are arranged directly opposite each other.

[0045] In practice, a current whose magnitude and direction can be controlled can be passed through the first drive coil group 7, thereby generating an interaction force whose direction and magnitude can be controlled between the first magnet group 21 fixed to the first yoke 22 and the first drive coil group 7 fixed to the gimbal outer support 9, and the first yoke 22 (first magnet group 21) can be driven to generate Rx- and Ry-axis rotational motion whose direction can be controlled relative to the gimbal outer support 9, and the gimbal inner support 5 (camera module 103) can be directly linked to generate Rx- and Ry-axis rotational motion to perform image stabilization along the Rx and Ry axes. 5 and 6b, the first magnet group 21 includes two first magnets (21A and 21B, respectively), and the first drive coil group 7 includes two first coils (7A and 7B, respectively). In this case, the first coil 7A and the first magnet 21A are provided facing each other, and the first coil 7B and the first magnet 21B are provided facing each other. When the force receiving directions of the first magnets 21A and 21B are the same as the Z axis or the same as the -Z axis, the gimbal inner support 5 is driven to rotate in the Ry direction relative to the gimbal outer support 9, and when the force receiving directions of the first magnets 21A and 21B are different, i.e., one is the same as the Z axis and the other is the same as the -Z axis, the gimbal inner support 5 is driven to rotate in the Rx axis direction relative to the gimbal outer support 9.

[0046] In a specific implementation, a second through hole 903 may be drilled in the gimbal outer support 9, so that the coils in the first drive coil group 7 are respectively fitted into the second through hole 903, and further a fixed connection between the first drive coil group 7 and the gimbal outer support 9 is realized.

[0047] In addition, the above-mentioned first yoke 22 being fixed to the first outer wall of the gimbal support 5 may also mean that the first yoke 22 is directly or indirectly fixed to the first outer wall of the gimbal support 5, and for example, as shown in Figure 7e, a rolling support 18 fixed to the gimbal support 5 may be provided, whereby the first yoke 22 is fixed to the gimbal support 5 by the rolling support 18.

[0048] Furthermore, in order to realize the flow of controllable current of magnitude and direction to the first drive coil group 7, the first drive coil group 7 may be connected to a first drive circuit board 601, which may be attached to the outside of the gimbal outer support 9, and the first drive coil group 7 is attached to the first drive circuit board 601 through the second through hole 903, thereby providing a controllable current of magnitude and direction to the first drive coil group 7 by the first drive circuit board 601.

[0049] In practice, the magnitude and direction of the current flowing through the first drive coil group 7 may be controlled by a controller in an electronic device equipped with a 3-axis gimbal provided in the embodiments of the present application. In this case, a first interface 603 may be provided on the outside of the first drive circuit board 601, thereby realizing a data communication connection with the controller in the electronic device through the first interface 603. Specifically, as shown in FIG. 6b, the first interface 603 may be connected to the first drive circuit board 601 via a connection plate 602.

[0050] In practical use, a first group of position feedback elements (8A and 8B) may be attached to the first drive circuit board 601, whereby the first group of position feedback elements (8A and 8B) detect the amount of rotation of the gimbal inner support 5 relative to the gimbal outer support 9 along the Rx and Ry axes, making it easier to accurately control the amount of rotation.

[0051] In practice, as shown in FIG. 6b, the first position feedback element group 8 may be a Hall element and may be disposed within the magnetic field range of the first magnet group 21 and the first driving coil group 7, thereby detecting the change in the magnetic field to measure the displacement amount of the first magnet group 21 relative to the first yoke 22, and based on this, the rotation amount along the Rx-axis and Ry-axis directions of the gimbal inner support 5 relative to the gimbal outer support 9 is measured.

[0052] Of course, in a specific implementation, the first position feedback element group 8 may be a driving chip, which can not only control the flow of a controllable current of magnitude and direction to the first driving coil group 7, but can also feedback the amount of rotation in the Rx-axis and Ry-axis directions.

[0053] Optionally, the first driving mechanism 101 further includes an outer yoke 24 , which is fixed to the gimbal outer support 9 and forms a magnetic circuit together with the first magnet group 21 .

[0054] In practice, the outer yoke 24 may be fixed to the outside of the first driving circuit board 601, as shown in FIG. 6b.

[0055] The outer yoke 24 serves to increase the driving force of the first driving mechanism 101, and improve the image stabilization effect along the Rx-axis and Ry-axis directions of the camera structure provided in the embodiment of the present application.

[0056] Optionally, the second driving mechanism 102 includes a second yoke (in this embodiment, the second yoke and the first yoke are the same yoke 22), a second driving coil group 15, and a second magnet group 17; The second drive coil group 15 is fixed to the gimbal carrier 10, the second yoke 22 is fixed to the first outer wall of the gimbal inner support 5, and the second magnet group 17 is fixed to the second yoke 22, and the second magnet group 17 and the second drive coil group 15 are fitted to each other; At least two coils in the second drive coil group 15 are spaced apart in a first direction, the first direction being perpendicular to the third axis, and the second drive coil group 15 are distributed on opposite sides of an axis of symmetry of the gimbal carrier 10, the axis of symmetry being the same as the direction from the first outer wall of the gimbal intra-support 5 to the first inner wall of the gimbal extra-support 9; Here, when current is passed through the second drive coil group 15, an interaction force is generated between the second drive coil group 15 and the second magnet group 17, and based on the interaction force, the second magnet group 17 drives the gimbal carrier 10 to rotate around the third axis relative to the gimbal internal support 5.

[0057] It should be noted that in the embodiment of the present application, the first yoke and the second yoke are the same yoke 22, and the first magnet group 21 and the second magnet group 17 are fixed to the opposite sides of the yoke 22, respectively, thus reducing the number of yokes in the camera structure provided in the embodiment of the present application, thereby reducing the volume and reducing the cost. Of course, if space and cost allow, the first yoke and the second yoke may be different yokes, and are not specifically limited here.

[0058] In practice, as shown in Fig. 7b, a through hole may be provided in the first yoke 22, so that a locking structure 502 extending from the first outer wall of the gimbal intra-support 5 is locked in the through hole. In addition, the gimbal carrier 10 is movably connected to the bottom of the gimbal intra-support 5, so that the second drive coil group 15 fixed to the gimbal carrier 10 is positioned between the first outer wall of the gimbal intra-support 5 and the first yoke 22. Furthermore, when a controllable current having a magnitude and a direction is applied to the second drive coil group 15, an interaction force is generated between the second drive coil group 15 and the second magnet group 17 fixed to the side of the first yoke 22 facing the second drive coil group 15, so that the second magnet group 17 can drive the gimbal carrier 10 to rotate around the third axis relative to the gimbal intra-support 5 based on the interaction force.

[0059] Furthermore, in order to realize a controllable flow of current of magnitude and direction into the second drive coil group 15, the second drive coil group 15 may be connected to a second drive circuit board 13, which may be attached to the outer wall of the gimbal carrier 10, and the second drive coil group 15 may be attached to the second drive circuit board 13, and a second drive chip 16 connected to the second drive coil group 15 is provided on the second drive circuit board 13, thereby controlling the magnitude and direction of the current input to the second drive coil group 15 by the second drive chip 16.

[0060] Furthermore, in practical use, a second position feedback element group may be attached to the second drive circuit board 13 (in this embodiment, the second position feedback element group and the second drive chip 16 are the same component), whereby the amount of rotation of the gimbal carrier 10 along the third axis relative to the gimbal intra-support 5 is obtained by the second drive chip 16, making it easier to accurately control the amount of Rz-axis rotation.

[0061] Of course, in a specific implementation, the second position feedback element group may be a component different from the second driving chip 16. For example, the second position feedback element group may include a Hall element and be arranged within the magnetic field range of the second driving coil group 15 and the second magnet group 17, thereby detecting changes in the magnetic field to measure the displacement amount of the second driving coil group 15 relative to the second yoke 22, and based on this, the rotation amount of the gimbal carrier 10 along the Rz axis direction relative to the gimbal intra-support 5 is measured.

[0062] In a specific implementation, the first position feedback element group 8 may be a driving chip, which can not only control the input of a current whose magnitude and direction can be controlled to the second driving coil group 15, but can also feedback the amount of rotation in the Rx and Ry directions.

[0063] 7a, the second drive circuit board 13 may have a bent structure so as to be attached to adjacent side walls (e.g., the first outer wall and the bottom wall shown in FIG. 7a) of the gimbal carrier 10. A circuit board reinforcement member 12 that matches the structure of the second drive circuit board 13 may be provided, and the second drive circuit board 13 is attached to the circuit board reinforcement member 12, thereby improving the structural strength of the second drive circuit board 13.

[0064] Optionally, the second drive mechanism 102 further includes an inner yoke (not shown), which is fixed to the gimbal carrier 10 and forms a magnetic circuit together with the second magnet group 17.

[0065] In practice, the inner yoke may be fixed to the side of the second drive circuit board 13 facing away from the second drive coil group 15; for example, as shown in FIG. 7a, a groove 1004 is provided on the outer wall of the gimbal carrier 10, whereby the inner yoke is fitted into the groove 1004 and sandwiched between the gimbal carrier 10 and the second drive circuit board 13.

[0066] The inner yoke 4 serves to increase the driving force of the second driving mechanism 102, and improve the image stabilization effect along the Rz axis direction of the camera structure provided in the embodiment of the present application.

[0067] Optionally, as shown in FIG. 4A and FIG. 4B, a first through hole 251 is formed in each of the support parts 25, and the axial direction of the first through hole 251 is perpendicular to the third axis. The camera structure further comprises an intermediate connection structure including a clamping part 3 (e.g., a U-shaped arm) and a first ball 4; The first ball 4 is inserted into the first through hole 251 and is sandwiched between both side walls of the clamping portion 3. Here, the clamping portion 3 is for fixed connection to the gimbal outer support 9 or the gimbal inner support 5 .

[0068] Specifically, as shown in Fig. 4a, the four corners of the universal shaft 2 extend in the direction opposite to the z-axis and are connected to one intermediate connection structure each. In assembly, the first ball 4 may be first inserted into the first through hole 251, and then inserted into the clamping part 3 as a whole.

[0069] Furthermore, as shown in FIG. 4c, the opposing side walls of the clamping portion 3 may be recessed in a direction away from each other, so that when the first ball 4 is engaged in the clamping portion 3, it can be engaged at a permanent position within the clamping portion 3; specifically, the opposing side walls of the clamping portion 3 are provided with ball retaining structures 303 and 307, respectively, of which 307 is located on the opposite side of 303, and 303 is elastically connected to the side wall on which 307 is located, so that the first ball 4 and the support portion 25 can be easily assembled; and an opening 306 is provided at the bottom of the clamping portion 3 to reduce the elastic force between the opposing side walls of the clamping portion 3.

[0070] Further, as shown in FIG. 4c, FIG. 4d and FIG. 4e, the intermediate connection structure further includes a guide plate 302, the guide plate 302 is fixedly connected to the first side wall of the clamping portion 3 and extends in a direction approaching the second side wall of the clamping portion 3, the first side wall of the clamping portion 3 and the second side wall of the clamping portion 3 are opposite side walls of the clamping portion 3; and / or The intermediate connection structure further includes a regulating plate 304, which is fixed to one end of the clamping part 3 away from the universal shaft 2 (e.g., the bottom of the groove of the U-shaped arm), thereby regulating the rotation angle of the support part 25 when the support part 25 rotates relative to the clamping part 3 to be smaller than a predetermined angle.

[0071] In practice, the first side wall of the clamping portion 3 may be located on the side of the clamping portion 3 that is away from the center of the universal shaft 2, and the number of the guide plates 302 is two, and the two guide plates 302 are located on opposite sides of the first side wall of the clamping portion 3, thereby playing the role of a guide so that the support portion 25 is aligned between the two guide plates 302 during assembly.

[0072] In addition, one end of the regulating plate 304 that is not fixed to the clamping portion 3 may be tilted outward, so that when the support portion 25 rotates a predetermined angle around the first ball 4, the support portion 25 abuts against the regulating plate 304, thereby regulating further rotation of the support portion 25.

[0073] Optionally, as shown in Figures 5 and 6a, the gimbal outer support 9 and the gimbal inner support 5 are provided with locking grooves (501, 901) that fit the clamping portion 3, and the clamping portion 3 is locked into the locking grooves (501, 901), thereby hinge-connecting the support portion 25 to the gimbal outer support 9 or the gimbal inner support 5.

[0074] Specifically, the two support portions 25 in the axial direction of the first axis of the universal shaft 2 are respectively engaged in two locking grooves 901 on the diagonal of the gimbal outer support 9, and the two support portions 25 in the axial direction of the second axis of the universal shaft 2 are respectively engaged in two locking grooves 501 on the diagonal of the gimbal inner support 5.

[0075] In this embodiment, by opening locking grooves (501, 901) in the gimbal outer support 9 and the gimbal inner support 5, the height of the universal shaft 2, the gimbal outer support 9 and the gimbal inner support 5 in the z-axis direction can be reduced, and the overall size of the camera structure provided in the examples of this application can be further reduced.

[0076] Optionally, as shown in FIG. 8b, the camera module 103 includes a camera component 20 and a first circuit board 23; The camera component 20 is fixed to the gimbal carrier 10 , the first circuit board 23 is fixed to the side of the camera component 20 remote from the gimbal carrier 10 , and the first circuit board 23 is movably connected to the gimbal outer support 9 .

[0077] In implementation, the first circuit board 23 can transmit data signals and electrical signals of the camera component 20, the first circuit board 23 is fixed to the side of the camera component 20 away from the gimbal carrier 10, and the first circuit board 23 is movably connected to the gimbal outer support 9, so that the first circuit board 23 can rotate following the gimbal carrier 10.

[0078] Further, as shown in FIG. 8a, the first circuit board 23 includes a first sub-circuit board 2301, a second sub-circuit board 2303 and a flexible wiring 2302; The second sub-circuit board 2303 surrounds the first sub-circuit board 2301, and the first sub-circuit board 2301 and the second sub-circuit board 2303 are in the same plane. The first sub-circuit board 2301 and the second sub-circuit board 2303 are movably connected via a flexible wiring 2302 .

[0079] In a specific implementation, the flexible wiring 2302 may be a planar spring structure, so that the first sub-circuit board 2301 and the second sub-circuit board 2303 can move relative to each other.

[0080] In addition, the second sub-circuit board 2303 may be provided with pads 2306 for connecting to an interface or connector, and the second sub-circuit board 2303 extends out of the case 1 from the bottom opening of the case 1, so that the pads 2306 are located outside the case 1, and the pads 2306 can connect the first circuit board 23 to the internal circuit of an electronic device equipped with the camera structure provided in the embodiments of the present application.

[0081] In this embodiment, a flexible wiring 2302 is connected between a first sub-circuit board 2301 and a second sub-circuit board 2303 which are in the same plane, and the flexible wiring 2302 has a planar spring structure, thereby realizing an elastic connection between the first sub-circuit board 2301 and the second sub-circuit board 2303, thereby reducing the space occupied by the first circuit board 23, and the dual camera component 20 can also be elastically connected to the gimbal outer support 9 by the first circuit board 23 to maintain the posture of the camera component 20.

[0082] Optionally, as shown in FIG. 7a and FIG. 7b, at least two first arc-shaped backing plates 504 are provided at the bottom of the gimbal inner support 5, and the ring on which the at least two first arc-shaped backing plates 504 are located is coaxial with the third axis; At least two second arc-shaped backing plates 1002 are provided on the gimbal carrier 10 in one-to-one correspondence with the at least two first arc-shaped backing plates 504, and one first arc-shaped backing plate 504 and one second arc-shaped backing plate 1002 form one arc-shaped backing plate group; The camera arrangement further comprises a second ball 11, A second ball 11 is sandwiched within each of the groups of arcuate backing plates.

[0083] The second ball 11 is only able to rotate around the z-axis under the restrictive action of the group of arc-shaped contact plates, so that when the gimbal carrier receives a force, it can only rotate around the z-axis, improving the accuracy of image stabilization in the Rz-axis direction.

[0084] Furthermore, a rotation restricting portion 1003 may be provided at one end of the second arcuate contact plate 1002 to restrict the amount of rotation of the gimbal carrier 10 relative to the in-gimbals support 5 along the Rz axis direction.

[0085] Of course, in a specific implementation, the rotation of the gimbal carrier 10 around the z-axis relative to the gimbal internal support 5 may be restricted by providing a slide rail and slider between the gimbal internal support 5 and the gimbal carrier 10, and a detailed description thereof will be omitted here.

[0086] Optionally, as shown in FIG. 7c, the camera structure further comprises a rolling support 18, The rolling support 18 is fixed to the gimbal in-support 5 and abuts against the side of the gimbal carrier 10 facing away from the gimbal in-support 5, thereby restricting the movement of the gimbal carrier 10 along the direction of the third axis.

[0087] In this embodiment, the gimbal carrier 10 is sandwiched between the rolling supports 18 and the intra-gimbal supports 5 to restrict the movement of the camera module 103 along the z-axis axial direction by the intra-gimbal supports 5, further improving the precision of the camera structure.

[0088] Furthermore, as shown in FIG. 7d, a groove or a through hole may be opened in the bottom surface of the gimbal carrier 10 that is bonded to the rolling support 18, and a second ball 19 is sandwiched in the groove or through hole, thereby reducing the friction force between the rolling support 18 and the gimbal carrier 10, and further improving the sensitivity with which the second driving mechanism 102 drives the gimbal carrier 10.

[0089] Specifically, as shown in FIG. 7e, the rolling support 18 has an integral structure, and specifically includes an engagement structure 1801 for engaging with the gimbal support 5, a platform 1803 for supporting the second ball 19, and a mounting plate 1805 for fixing the first yoke 22, and a third through hole is drilled in the mounting plate 1805, so that the locking structure on the gimbal support 5 passes through the third through hole and is fixedly connected to the mounting plate 1805 and the first yoke 22, respectively.

[0090] The first yoke 22 may be fixed to the gimbal intra-support 5 by being sandwiched between the gimbal intra-support 5 and a mounting plate 1805, and the mounting plate 1805 is provided with a spacing portion 1808 protruding in a direction away from the gimbal carrier 10, which spacing portion 1808 separates the mounting plate 1805 into two parts, so that when the first magnet group 21 is mounted on the side of the mounting plate 1805 facing away from the gimbal carrier 10, the magnets in the first magnet group 21 are separated by the spacing portion 1808 and the magnets in the first magnet group 21 are each restricted at this portion, thereby increasing the fixing strength of the magnets in the first magnet group 21.

[0091] From the above, the camera structure provided in the embodiment of the present application has the following beneficial effects: It can drive the rotation of the camera module in the Rx, Ry, and Rz directions. In addition to preventing the vibration in the Rx, Ry, and Rz directions, it can also prevent the translational vibration in the axial direction of the X-axis and Y-axis by incorporating corresponding algorithm processing, so that it can have a total of five axial anti-shake effects. By providing the electromagnetic driving module (the first driving mechanism and the second driving mechanism) on one side of the camera structure, more non-magnetic areas can be freed up on the other three sides of the camera structure, which contributes to the layout of the multi-axis anti-shake mechanism. By adopting the planar spring circuit board structure, the circuit board is arranged in a planar manner in the bottom space of the gimbal, and there is no need to bend the circuit board several times, thus reducing the occupied space of the circuit board, reducing the overall volume of the camera structure, and further freeing up more space for the layout of other devices, such as increasing the size and capacity of the battery, thereby extending the duration of the mobile phone and indirectly improving the consumer's continuous use experience. A gimbal carrier structure and its driving structure capable of rotating in the Rz direction are provided in the middle of the camera structure, and are independent of the movements of Rx and Ry, so that crosstalk caused by three-axis synchronous driving can be effectively reduced. The second driving coil group 15 and driving elements are provided on the gimbal carrier 10, and can be routed from the first circuit board 23 and connected to an external circuit, while the first driving coil group 7 and the first position feedback element group 8 are provided on one side of the camera structure and fixed to the gimbal outer support 9, and can be directly routed and connected to an external circuit. A two-sided clamping support structure for clamping the first ball 4 is adopted, which can reduce the influence of interlocking shake in multiple degrees of freedom, reduce the change of camera external parameters, and strongly support the multi-camera fusion algorithm.

[0092] An embodiment of the present application further provides an electronic device comprising any of the camera structures in Figs. 1 to 8b.
