Technical Field

[0002] At present, electronic devices such as mobile phones and tablet computers need to maintain stable shooting quality under different brightness conditions. In order to achieve this goal, some camera modules are provided with a variable aperture (VA) on the light-entering side of the optical lens. The size of the light hole of the variable aperture can be changed. In a high-brightness environment, the size of the light hole can be reduced so that relatively less light enters the optical lens. In a low-brightness environment, the size of the light hole can be increased so that relatively more light enters the optical lens. This achieves the adjustment of the amount of light entering the optical lens and ensures the shooting quality.

[0003] In addition, some camera modules are also integrated with a drive motor, which is used to drive the movement of the optical lens to achieve automatic focusing (AF) and optical image stabilization (OIS), thereby ensuring the shooting clarity of the electronic device.

[0004] For camera modules that integrate both a variable aperture and a drive motor, since there are many drive components, how to simplify the circuit design of the camera module has become one of the important topics in the industry. Utility Model Content

[0072] The base 02 is disposed on a circuit board 09 . A photosensitive element 091 is disposed on the circuit board 09 . The photosensitive element 091 is located in a relief opening 020 on the base 02 , and the photosensitive element 091 is located on the image side of the optical lens 05 .

[0073] The housing 01 is disposed on the base 02, and the housing 01 and the base 02 enclose a housing cavity 011. The motion seat 03 and the lens seat 04 are both disposed in the housing cavity 011, the motion seat 03 is disposed on the base 02, the lens seat 04 is disposed on the motion seat 03, and the lens seat 04 is provided with a lens mounting hole 041, in which the optical lens 05 is mounted.

[0074] The focus driver 08 is used to drive the lens holder 04 to move along the axial direction Z of the variable aperture 06 relative to the moving holder 03, wherein the focus driver 08 includes a focus drive coil 081 disposed on the moving holder 03, and a first magnet 082 disposed on the lens holder 04. When focusing, the focus drive coil 081 is energized, and the magnetic field of the first magnet 082 interacts with the focus drive coil 081, so that the lens holder 04 moves along the axial direction Z, thereby driving the optical lens 05 to move along the axial direction Z, so as to achieve the focus of the camera module.

[0075] The anti-shake driver 07 is used to drive the moving seat 03 to move relative to the base 02 in a direction perpendicular to the axial direction Z, wherein the anti-shake driver 07 includes an anti-shake driving coil 071 disposed on the base 02, and a second magnet 072 disposed on the moving seat 03. During anti-shake, the anti-shake driving coil 071 is energized, and the magnetic field of the second magnet 072 interacts with the anti-shake driving coil 071, so that the moving seat 03 moves in a direction perpendicular to the axial direction Z, thereby driving the optical lens 05 to move in a direction perpendicular to the axial direction Z, so as to achieve anti-shake of the camera module.

[0076] The variable aperture 06 is disposed on the lens holder 04 and is located at the light incident side of the optical lens 05 . The variable aperture 06 is used to adjust the amount of light entering the optical lens 05 .

The anti-shake driving device 6 is used to drive the moving seat 2 to move relative to the base 1 along the direction perpendicular to the axial direction Z. Among them, the "vertical" in the direction perpendicular to the axial direction Z can be either absolutely vertical or approximately vertical (with a deviation within 3 degrees).

[0096] In some embodiments, Figure 5 and Figure 6 As shown, the lens driving device 700 also includes a shell 9, which is arranged on the base 1. The shell 9 and the base 1 form a accommodating space, which is used to accommodate the moving seat 2, the lens seat 3, the focus driving device 5 and the anti-shake driving device 6.

[0097] Fig.10 for Figure 6 A schematic diagram of the structure of the variable aperture 4 of the camera module 300, Fig.11 for Fig.10 Exploded view of the variable aperture 4 in the Fig.12 for Fig.10 DD cross-sectional view of variable aperture 4 in Fig.13 for Fig.10 The structure diagram of the variable aperture 4 after removing the top plate 48 is shown in FIG. Figure 10 to Figure 13 As shown, the variable aperture 4 includes an aperture base 41, an aperture driver 42, an aperture rotor 43 arranged on the aperture base 41, and blades 44 arranged on the aperture rotor 43. The aperture driver 42 is used to drive the variable aperture 4 to change the amount of light passing through. Specifically, the aperture driver 42 is used to drive the aperture rotor 43 to rotate relative to the aperture base 41, and the blades 44 can move with the aperture rotor 43 to change the amount of light passing through.

[0098] Among them, Fig.11 and Fig.12 As shown, the aperture base 41 includes a light-transmitting cylinder 411 and a bearing flange 412 disposed at a first end edge of the light-transmitting cylinder 411 . The bearing flange 412 extends radially along the light-transmitting cylinder 411 . The cylinder hole of the light-transmitting cylinder 411 is a light-transmitting hole of the variable aperture 4 .

[0099] The aperture rotor 43 is annular and rotatably sleeved on the second end of the light-transmitting cylinder 411. The aperture driver 42 is disposed between the bearing flange 412 and the aperture rotor 43. The aperture driver 42 includes an aperture driving coil 421 disposed on the aperture rotor 43 and a first magnet 422 disposed on the bearing flange 412, and the aperture driving coil 421 and the first magnet 422 are disposed opposite to each other.

[0100] like Fig.13 As shown, the blade 44 is located at the end surface of the second end of the light-transmitting tube 411, and the blade 44 is connected to the aperture rotor 43 through a connecting structure. The blade 44 has a swing end 441 and a connecting end 442. The swing end 441 of the blade 44 is arranged close to the axis 40 of the light-transmitting tube 411, and the connecting end 442 of the blade 44 is arranged away from the axis 40 of the light-transmitting tube 411.

[0101] The connection structure includes an arc groove 443 arranged at the connection end 442 of the blade 44, and a sliding column 431 arranged on the aperture rotor 43. One end of the arc groove 443 is arranged close to the axis 40 of the light-transmitting tube 411, and the other end is arranged away from the axis 40 of the light-transmitting tube 411. The sliding column 431 slides in cooperation with the arc groove 443.

[0102] When the variable aperture 4 adjusts the light transmittance of the optical lens 400, the aperture driving coil 421 is energized, and the magnetic field of the first magnet 422 interacts with the aperture driving coil 421, causing the aperture rotor 43 to rotate relative to the light tube 411. The aperture rotor 43 drives the slide post 431 to slide along the arc groove 443, and the blade 44 swings under the action of the slide post 431, so that the swing end 441 of the blade 44 is away from or close to the axis 40 of the light tube 411, so as to adjust the size of the light hole of the variable aperture 4, thereby changing the light transmittance of the variable aperture 4.

[0103] Among them, Fig.13 As shown, there are multiple blades 44 , for example, six blades 44 , and the multiple blades 44 are arranged along the circumferential direction of the aperture rotor 43 .

[0104] Of course, in the aperture driver 42, the positions of the aperture drive coil 421 and the first magnet 422 can also be interchanged, that is, the aperture drive coil 421 is disposed on the bearing flange 412, and the first magnet 422 is disposed on the aperture rotor 43. In the connection structure, the positions of the slide post 431 and the arc groove 443 can also be interchanged, that is, the arc groove 443 is disposed on the aperture rotor 43, and the slide post 431 is disposed on the blade 44.

[0105] In some embodiments, Fig.11 and Fig.13 As shown, the bearing flange 412 is provided with a plurality of limiting bosses 413 (eg Fig.13 ), the plurality of limiting bosses 413 are arranged along the circumference of the light-through cylinder 411, and a limiting space is formed between two adjacent limiting bosses 413. The edge of the aperture rotor 43 is provided with a rotor flange 432, and the rotor flange 432 extends into the limiting space. In this way, the limiting bosses 413 can limit the rotation angle range of the aperture rotor 43, so that the swing amplitude of the blades 44 can be accurately controlled to meet the adjustment of the size of the light-through hole.

Compared with placing the aperture elastic member 47 flat relative to the bearing flange 412, placing the aperture elastic member 47 upright relative to the bearing flange 412 can reduce the space occupied by the aperture elastic member 47.

[0108] The plane where the circuitous line is located is parallel to the axial direction Z of the variable aperture 4 , and can be absolutely parallel or approximately parallel (for example, the deviation is 5 degrees), which is not specifically limited here.

In this arrangement, on the one hand, the top plate 48 can limit the blade 44 to prevent the blade 44 from being separated from the aperture rotor 43, and on the other hand, the top plate 48 can also protect the blade 44 to prevent the blade 44 from being damaged.

[0110] In some embodiments, a top plate groove 481 is provided at the edge of the top plate 48, and a limiting column 4131 is provided on the limiting boss 413, and the limiting column 4131 is disposed in the top plate groove 481. In this way, the limiting column 4131 can play a role in rotation limiting the top plate 48, thereby preventing the top plate 48 from rotating relative to the aperture base 41.

The moving seat limiting portion 11 is used to limit the movement of the moving seat 2 perpendicular to the axial direction Z.

[0124] Among them, Fig.21 As shown, the moving seat limiting part 11 includes a limiting platform 111 and a limiting rib 112, the limiting platform 111 is arranged at the corner 12 of the base 1, the limiting rib 112 is arranged at the side 13 of the base 1, and the limiting platform 111 and the limiting rib 112 are arranged along the circumferential direction of the base 1. Of course, the structure of the moving seat limiting part 11 is not limited to this, and can also be set to other structures according to actual conditions.

[0126] During anti-shake, the anti-shake drive coil 611 is energized, and the magnetic field of the third magnet 612 interacts with the anti-shake drive coil 611, causing the moving seat 2 to move in a direction perpendicular to the axial direction Z, thereby driving the lens seat 3 and the optical lens 400 to move in a direction perpendicular to the axial direction Z to achieve anti-shake of the camera module 300.

[0127] Of course, the locations of the anti-shake driving coil 611 and the third magnet 612 may also be swapped, that is, the anti-shake driving coil 611 is disposed on the moving seat 2 , and the third magnet 612 is disposed on the base 1 .

With such an arrangement, the camera module 300 can achieve anti-shake in the first direction X and the second direction Y.

[0129] In some embodiments, Fig.21 , Fig.23 and Fig.24 As shown, Fig.23 for Fig.21 Schematic diagram of the base 1 and the slide 7 being installed together, Fig.24 for Fig.21 The schematic diagram of the structure of the bottom of the motion base 2 of the camera module 300 in FIG. The base 1 is provided with a second sliding shaft 14 and a sliding seat 7, the second sliding shaft 14 extends along the second direction Y, and the sliding seat 7 is provided with a first sliding groove 71, the first sliding groove 71 is slidably matched with the second sliding shaft 14, so that the sliding seat 7 is slidably connected with the base 1 along the second direction Y.

The moving seat 2 is provided with a second slide groove 25, which slides with the third slide shaft 72 so that the moving seat 2 is slidably connected with the slide seat 7 along the first direction X.

[0131] When the camera module 300 needs to be anti-shake in the second direction Y, the anti-shake driving device 6 at the second side 132 drives the slide 7 to move relative to the base 1 along the second direction Y, the slide 7 drives the moving seat 2 to move relative to the base 1 along the second direction Y, and the moving seat 2 drives the lens seat 3 and the optical lens 400 to move relative to the base 1 along the second direction Y, thereby realizing anti-shake of the camera module 300 in the second direction Y.

[0132] When the camera module 300 needs to be anti-shake in the first direction X, the anti-shake driving device 6 at the first side edge 131 drives the moving seat 2 to move relative to the slide seat 7 along the first direction X, and the moving seat 2 drives the lens seat 3 and the optical lens 400 to move relative to the slide seat 7 along the first direction X, thereby achieving anti-shake of the camera module 300 in the first direction X.

[0133] By providing the second sliding shaft 14, the second sliding shaft 14 can guide the sliding seat 7, so that the sliding seat 7 drives the moving seat 2 to move more smoothly in the second direction Y. By providing the third sliding shaft 72, the third sliding shaft 72 can guide the moving seat 2, so that the moving seat 2 can move more smoothly in the first direction X.

[0135] In some embodiments, Fig.21 As shown, the slide 7 is in an "L" shape, a portion of the slide 7 is located at the first side 131 of the base 1, and another portion of the slide 7 is located at the second side 132 of the base 1. By setting the slide 7 in an "L" shape, the space occupied by the slide 7 on the base 1 can be reduced. Of course, the slide 7 is not limited to being set in an "L" shape, and can also be set in other shapes according to actual conditions.

[0136] In some embodiments, Fig.25 and Fig.26 As shown, Fig.25 for Fig.23 The schematic diagram of the structure of the base 1 after removing the anti-shake drive coil 611 and the slide seat 7 is shown. Fig.26 for Fig.25 The exploded view of the base 1 and the pins arranged on the base 1 in FIG. The base 1 has a plurality of corner portions 12 along the circumference, and a first pin 15 is arranged at the plurality of corner portions 12. The first pin 15 has a first connection end 151 and a second connection end 152. The second connection end 152 is an external connection end and is electrically connected to the module circuit board 600. Figure 6 and Fig.21 As shown, the first connection end 151 is electrically connected to the variable aperture 4 and the focus driving device 5 through the connecting line 8.

[0137] Among them, Fig.25 and Fig.26As shown, the base 1 has a rectangular outline, and the base 1 has four corners 12 along the circumferential direction, and first pins 15 are provided at three corners 12. The three corners 12 are respectively provided with a first pin 15 at a corner 12a, a corner 12b, and a corner 12c, and two first pins 15 are provided at the corner 12b. Of course, the outline of the base 1 is not limited to a rectangle, and can also be set to other polygons, such as a hexagon, a pentagon, etc. In addition to providing the first pins 15 at the three corners 12 of the base 1, the first pins 15 can also be provided at four or two corners 12 of the base 1, which can be determined according to actual conditions.

[0138] By electrically connecting the first connection end 151 of the first pin 15 to the variable aperture 4 and the focus driving device 5, that is, the variable aperture 4 and the focus driving device 5 share the first pin 15, the number of pins of the lens driving device 700 can be reduced, thereby simplifying the circuit design of the lens driving device 700. By arranging multiple first pins 15 at multiple corners 12 of the base 1, it is convenient to electrically connect the first pins 15 to the connecting circuit 8, and there is no need to arrange a conductive member and an intermediate connecting circuit 8 between the first pin 15 and the connecting circuit 8, which simplifies the circuit design of the lens driving device 700, thereby simplifying the circuit design of the entire camera module 300, and further facilitating the working reliability of the circuit of the camera module 300.

[0139] In some embodiments, Fig.21 , Fig.25 and Fig.26 As shown, the first pin 15 is embedded in the base 1, and the first connection end 151 is exposed from the surface of the base 1 and connected to the connection line 8, and the second connection end 152 extends out of the base 1. By embedding the first pin 15 in the base 1, it is not only possible to avoid the first pin 15 from occupying additional space outside the base 1, making the structure of the lens driving device 700 more compact, but the base 1 can also protect the embedded first pin 15, reducing corrosion damage to the first pin 15 by the outside.

[0140] In some embodiments, Fig.25 As shown, a portion of the first pin 15 is embedded in the limiting platform 111, and the first connection end 151 is exposed from the end surface of the limiting platform 111. This arrangement can make the first connection end 151 closer to the motion seat 2, shorten the path of the connection line 8, and make the connection between the first connection end 151 and the connection line 8 more convenient. Of course, the first connection end 151 is not limited to being located on the limiting platform 111, and can also be set at other positions of the base 1.

The first terminal 82 is electrically connected to the focus driving device 5 through a focus wire 85. The second terminal 83 is arranged on the lens seat 3 and is electrically connected to the variable aperture 4. The second terminal 83 is electrically connected to the first terminal 82 through a second elastic wire 86. Figure 6 and Fig.10 As shown, the second terminal 83 is electrically connected to the external connection end of the variable aperture 4 (such as the second connection ear 462 of the variable aperture 4).

[0142] By arranging the first elastic wire 84 between the first terminal 82 and the connection contact 81, the first elastic wire 84 not only plays the role of electrical connection, but also elastically deforms when the moving seat 2 moves along the direction perpendicular to the axial direction Z, so as to provide a reset force to the moving seat 2. By arranging the second elastic wire 86 between the second terminal 83 and the first terminal 82, the second elastic wire 86 not only plays the role of electrical connection, but also elastically deforms when the lens holder 3 moves along the axial direction Z, so as to provide a reset force to the lens holder 3.

[0143] Each first pin 15 is electrically connected to the focus driving device 5 and the variable aperture 4 through the connecting line 8. For example, Figure 15 to Figure 18 As shown, the four first pins 15 are electrically connected to the focus driving device 5 and the variable aperture 4 through the connecting circuits 8, respectively. In two of the connecting circuits 8, the first terminal 82 is arranged on the side of the moving seat 2 close to the first side 131, and the first elastic wiring 84 can be elastically deformed in the second direction Y to provide a restoring force to the moving seat 2 in the second direction Y. In the other two connecting circuits 8, the first terminal 82 is arranged on the side of the moving seat 2 close to the second side 132, and the first elastic wiring 84 can be elastically deformed in the first direction X to provide a restoring force to the moving seat 2 in the first direction X.

[0144] like Fig.15 and Fig.16 As shown, the connection contact 81 is welded to the first connection end 151, but it is not limited thereto. In addition to welding, the connection contact 81 can also be connected to the first connection end 151 by a fastener (such as a screw). Fig.15 and Fig.16 As shown, the connection pad 81 is a sheet-like structure, but is not limited thereto. In addition to the sheet-like structure, the connection pad 81 may also be a block-like structure, a columnar structure, etc.

By arranging the transfer wiring 88 and the transfer terminal 87, the transfer terminal 87 can be arranged at the end position of the second elastic wiring 86, and the first terminal 82 can be arranged at other positions on the moving seat 2, thereby facilitating the arrangement of the first terminal 82 on the moving seat 2, and further facilitating the arrangement of the first elastic wiring 84 between the first terminal 82 and the connecting contact 81.

[0146] In some embodiments, Fig.16 and Fig.17 As shown, the transfer wiring 88 is at least partially embedded in the motion seat 2. The transfer wiring 88 can be fully embedded in the motion seat 2 or partially embedded in the motion seat 2, which is not specifically limited here. By embedding the transfer wiring 88 at least partially in the motion seat 2, the space occupied by the transfer wiring 88 outside the motion seat 2 can be reduced, and the motion seat 2 can also protect the embedded transfer wiring 88, reducing corrosion damage to the transfer wiring 88 by the outside world.

[0147] In some embodiments, Fig.16 , Fig.17 and Fig.18 As shown, the focus driving device 5 includes a first control unit 52, the first control unit 52 is electrically connected to the focus driver 51, the focus wiring 85 is electrically connected to the first control unit 52, and the first control unit 52 is arranged on the side wall of the moving seat 2. By arranging the first control unit 52 on the side wall of the moving seat 2, the occupied space of the first control unit 52 on the moving seat 2 in the direction perpendicular to the axial direction Z can be reduced, thereby reducing the squeezing of the first control unit 52 on the setting space of the lens seat 3, which is conducive to the optimal arrangement of the lens seat 3.

[0148] In some embodiments, Fig.16 and Fig.18 As shown, the first control unit 52 is a driving chip, a coil avoidance opening 26 is provided on the side wall of the moving seat 2, and a focus driving coil 511 of the focus driver 51 is provided on the first control unit 52, and the focus driving coil 511 extends into the lens seat mounting hole 21 through the coil avoidance opening 26. By providing the focus driving coil 511 on the first control unit 52, the space occupied by the focus driving coil 511 and the first control unit 52 on the moving seat 2 can be reduced, thereby making the moving seat 2 more compact.

[0149] In some embodiments, Fig.16 , Fig.17 and Fig.18 As shown, the focus wiring 85 is embedded in the moving seat 2, and the focus wiring 85 has a control unit connection end 851, and the control unit connection end 851 is exposed from the side wall of the moving seat 2 and is electrically connected to the first control unit 52. By embedding the focus wiring 85 in the moving seat 2, the space occupied by the focus wiring 85 outside the moving seat 2 can be reduced, and the moving seat 2 can also protect the embedded focus wiring 85, reducing corrosion damage to the focus wiring 85 by the outside world.

[0177] Focus control: The processor 800 sends a focus instruction to the control unit 610, the control unit 610 obtains the position information of the lens mount 3, and then determines whether focus control is required based on the position information of the lens mount 3; if focus control is required, the control unit 610 performs a control operation based on the position information of the lens mount 3, and after the operation is completed, sends a control instruction to the first control unit 52, and after receiving the control instruction, the first control unit 52 sends a drive signal to the focus driver 51, and then the focus driver 51 drives the lens mount 3 to focus; if focus control is not required, the control unit 610 continues to obtain the position information of the lens mount 3 to determine whether focus control is required.

[0178] The position information of the lens mount 3 can be detected by the first position sensor 522 .

[0179] Control of the variable aperture 4: The processor 800 sends an aperture value adjustment instruction to the control unit 610, and the control unit 610 sends a control instruction to the third control unit 49. After receiving the control instruction, the third control unit 49 controls the aperture driver 42 in a closed loop to achieve the target aperture value.

Then, the anti-shake driver 61 drives the moving seat 2 to move to achieve anti-shake.

[0181] Among them, the posture information of the electronic device can be detected by the gyroscope 900.

[0182] Fig.31 FIG. 8 is a connection architecture diagram of a camera module 300 and a processor 800 of an electronic device in a second embodiment of the present application. Fig.32 1 is a circuit connection schematic diagram between the camera module 300 and the processor 800 of the electronic device in the second embodiment of the present application. The main difference between the camera module 300 in the second embodiment and the camera module 300 in the first embodiment is that the structure of the anti-shake driving device 6 and the connection method with the module circuit board 600 are different, as described below:

[0183] like Fig.31 and Fig.32 As shown, a control unit 610 and an external terminal 620 are provided on the module circuit board 600. The control unit 610 is electrically connected to the external terminal 620, the variable aperture 4 of the lens driving device 700, and the focus driving device 5 respectively.

[0185] In this embodiment, the anti-shake driver 61 is controlled by the second control unit 62 instead of the control unit 610, which can reduce the amount of calculation of the control unit 610, thereby facilitating the control unit 610 to better control the variable aperture 4 and the focus driving device 5. Since the sub-pins 161 of the second pin 16 are all electrically connected to the second control unit 62, the number of components connected between the second pin 16 and the anti-shake driving device 6 is reduced, thereby facilitating the reduction of the number of sub-pins 161 in the second pin 16, and facilitating the simplification of the circuit design of the camera module 300.

[0186] In some embodiments, Fig.33 As shown, Fig.33 for Fig.32 Schematic diagram of the composition of the first control unit 52, the second control unit 62, and the third control unit 49. The second control unit 62 includes a second controller 621 and a second position sensor 60, the second position sensor 60 and the anti-shake driver 61 are electrically connected to the second controller 621, respectively, and the second position sensor 60 is used to detect the position of the moving seat 2 relative to the base 1 in the direction perpendicular to the axial direction Z.

[0187] Since the second control unit 62 includes the second controller 621 and the second position sensor 60, that is, the second control unit 62 has a position detection function, the second control unit 62 can realize closed-loop control of the anti-shake driver 61 according to the data detected by the second position sensor 60, thereby making the anti-shake control of the anti-shake drive device 6 more precise.

[0188] In some embodiments, Fig.21 , Fig. 22 and Fig.32 As shown, a second pin 16 is provided at the first side 131 or the second side 132, and the second pin 16 is connected to the anti-shake driving device 6 (that is, Fig.32 In this way, the anti-shake driving devices 6 located at the first side 131 and the second side 132 share the second pin 16, which can reduce the number of sub-pins 161 of the second pin 16, thereby further simplifying the circuit design of the camera module 300.

[0189] In some embodiments, Fig.31 and Fig.32 As shown, the first connection line 650 includes an I2C / I3C line, a VCM VDD line, and a DGND line. The anti-shake driving device 6 and the photosensitive element 500 share at least part of the I2C / I3C line and the DGND line. This arrangement can further simplify the circuit design of the camera module 300.

[0190] The control process of the camera module 300 in the second embodiment of the present application is introduced below: Fig.34 As shown, Fig.34 This is a control flow chart of the camera module 300 in the second embodiment of the present application.

[0191] Focus control: The processor 800 sends a focus instruction to the control unit 610, the control unit 610 obtains the position information of the lens mount 3, and then determines whether focus control is required based on the position information of the lens mount 3; if focus control is required, the control unit 610 performs a control operation based on the position information of the lens mount 3, and after the operation is completed, sends a control instruction to the first control unit 52, and after receiving the control instruction, the first control unit 52 sends a drive signal to the focus driver 51, and then the focus driver 51 drives the lens mount 3 to focus; if focus control is not required, the control unit 610 continues to obtain the position information of the lens mount 3 to determine whether focus control is required.

[0192] The position information of the lens mount 3 can be detected by the first position sensor 522 .

[0193] Control of the variable aperture 4: The processor 800 sends an aperture value adjustment instruction to the control unit 610, and the control unit 610 sends a control instruction to the third control unit 49. After receiving the control instruction, the third control unit 49 controls the aperture driver 42 in a closed loop to achieve the target aperture value.

[0194] Anti-shake control: After the processor 800 enters the anti-shake control mode, the processor 800 calculates the movement amount of the motion seat 2 according to the posture information of the electronic device and the position information of the motion seat 2, and then the processor 800 sends a control signal that the motion seat 2 needs to move.

[0196] Fig.35 FIG. 8 is a connection architecture diagram of a camera module 300 and a processor 800 of an electronic device in a third embodiment of the present application. Fig.36 : This is a circuit connection schematic diagram between the camera module 300 in the third embodiment of the present application and the processor 800 of the electronic device. The main difference between the camera module 300 in the second embodiment and the camera module 300 in the second embodiment is that the connection method between the variable aperture 4, the focus driving device 5 and the anti-shake driving device 6 and the pins is different, as described below:

[0197] like Fig.35 and Fig.36 As shown, an external terminal 620 is provided on the module circuit board 600, and the variable aperture 4, focus drive device 5 and anti-shake drive device 6 of the lens drive device 700 are electrically connected to the external terminal 620 through the second connecting line 660 on the module circuit board 600, and the external terminal 620 is electrically connected to the processor 800.

[0198] Among them, Fig.35 As shown, the focus drive device 5 includes a first control unit 52 and a focus drive 51 electrically connected to the first control unit 52.

[0199] The anti-shake drive device 6 includes a second control unit 62 and an anti-shake driver 61 electrically connected to the second control unit 62. The anti-shake driver 61 is used to drive the moving seat 2 to move relative to the base 1 in a direction perpendicular to the axial direction Z. The second control unit 62 is used to send a driving signal to the anti-shake driver 61 to make the anti-shake driver 61 work.

[0200] The variable aperture 4 includes a third control unit 49 and an aperture driver 42 electrically connected to the third control unit 49. The aperture driver 42 is used to drive the aperture rotor 43 to rotate relative to the aperture base 41. The third control unit 49 is used to send a driving signal to the aperture driver 42 according to the target aperture value to be adjusted, so that the aperture driver 42 works. The first control unit 52, the second control unit 62, and the third control unit 49 are all electrically connected to the external terminal 620 through the second connecting line 660.

[0201] In this embodiment, the variable aperture 4, the focus drive device 5, and the anti-shake drive device 6 are controlled by their own control modules and do not need to be controlled by the control unit 610 on the module circuit board 600. In this way, there is no need to set the control unit 610 on the module circuit board 600, which not only saves space on the module circuit board 600, but also simplifies the circuit design on the module circuit board 600, thereby simplifying the circuit design of the camera module 300.

[0202] In some embodiments, Fig.36 As shown, the variable aperture 4 and the focus driving device 5 form a first module, and at least part of the first pins 15 are common pins of the first module and the second control unit 62. This arrangement can further reduce the number of pins of the lens driving device 700, thereby simplifying the circuit design of the camera module 300.

[0203] In some embodiments, Fig.36As shown, a portion of the first pins 15 are common pins and are electrically connected to the first control unit 52 , the second control unit 62 and the third control unit 49 , and another portion of the first pins 15 are electrically connected to the first control unit 52 and the third control unit 49 .

[0204] By making a part of the first pins 15 as shared pins, the number of pins of the lens driving device 700 can be reduced, and non-shared pins can be respectively set for the first module and the anti-shake driving device 6 to meet different configuration requirements of the first module and the anti-shake driving device 6, such as different configuration requirements of the power supply voltage.

[0205] For example, Fig.36 As shown, there are four first pins 15, three of which are common pins, which are electrically connected to the first control unit 52, the second control unit 62, and the third control unit 49 through the I2C / I3C line and the DGND line, and another first pin 15 is electrically connected to the first control unit 52 and the third control unit 49 through the AF / VA VDD line. A third pin is also provided on the base 1, and the third pin is electrically connected to the second control unit 62 through the VCM VDD line. The second connection trace 660 includes the I2C / I3C line, the VCM VDD line, the AF / VA VDD line, and the DGND line.

[0206] In some embodiments, the first control unit 52 includes a first controller 521 and a first position sensor 522, the first position sensor 522 and the focus driver 51 are electrically connected to the first controller 521, respectively, and the first position sensor 522 is used to detect the position of the lens mount 3 relative to the motion seat 2 in the axial direction Z; the second control unit 62 includes a second controller 621 and a second position sensor 60, the second position sensor 60 and the anti-shake driver 61 are electrically connected to the second controller 621, respectively, and the second position sensor 60 is used to detect the position of the motion seat 2 in a direction perpendicular to the axial direction Z; the third control unit 49 includes a third controller 491 and a third position sensor 492, the third position sensor 492 and the aperture driver 42 are electrically connected to the third controller 491, respectively, and the third position sensor 492 is used to detect the position of the aperture rotor 43 relative to the aperture base 41.

[0207] With such an arrangement, the first control unit 52, the second control unit 62, and the third control unit 49 can have a position detection function, so that the first control unit 52 can implement closed-loop control of the focus driver 51 according to the data detected by the first position sensor 522, the second control unit 62 can implement closed-loop control of the anti-shake driver 61 according to the data detected by the second position sensor 60, and the third control unit 49 can implement closed-loop control of the aperture driver 42 according to the data detected by the third position sensor 492, thereby making the focus control of the focus drive device 5, the adjustment control of the aperture value of the variable aperture 4, and the anti-shake control of the anti-shake drive device 6 more precise.

[0208] The control process of the camera module 300 in the third embodiment of the present application is introduced below: Fig.37 As shown, Fig.37 This is a control flow chart of the camera module 300 in the third embodiment of the present application.

[0211] Anti-shake control: After the processor 800 enters the anti-shake control mode, the processor 800 calculates the movement amount of the motion seat 2 according to the posture information of the electronic device and the position information of the motion seat 2, and then the processor 800 sends a control signal that the motion seat 2 needs to move. After receiving the control signal, the second control unit 62 controls the anti-shake driver 61 in a closed loop to move the motion seat 2 to the target position. Then, the processor 800 obtains the position information of the motion seat 2 to perform the next round of anti-shake control.

[0212] Among them, the posture information of the electronic device can be detected by the gyroscope 900.
