For ease of description, the side of the optical lens 10 facing the subject is the object side, and the side of the optical lens 10 facing the photosensitive component 30 is the image side. The optical axis direction includes the direction along the optical axis pointing to the image side (referred to as the image side in this application), and the direction along the optical axis pointing to the object side (referred to as the object side in this application). The horizontal direction is perpendicular to the optical axis direction, and the height direction is along the optical axis direction.

[0152] The driving device 20 further includes a lens focusing part 23 and a chip anti-shake part 24, wherein the lens focusing part 23 can drive the optical lens 10 to move in the Z-axis direction to adjust the distance between the optical lens 10 and the photosensitive component 30, thereby realizing the focusing function of the optical lens 10; wherein the chip anti-shake part 24 can drive the photosensitive component 30 to translate in the X-axis and Y-axis directions and / or rotate around the Z-axis direction to realize the translational anti-shake and / or rotational anti-shake function of the photosensitive component 30. In the embodiment of the present application, the X-axis direction and the Y-axis direction are perpendicular to each other, and the Z-axis direction is perpendicular to the plane where the X-axis direction and the Y-axis direction are located. In other words, the X-axis, Y-axis and Z-axis constitute a three-dimensional coordinate system, the XOY plane where the X-axis direction and the Y-axis direction are located is also called the plane where the horizontal direction is located, and the Z-axis approaches the optical axis direction or is parallel to the optical axis.

[0153] As shown in Figures 2 to 12B, in one embodiment of the present application, the driving device 20 includes a lens focusing portion 23 and a chip anti-shake portion 24. The optical lens 10 is disposed in the lens focusing portion 23, which is configured to drive the optical lens 10 to move to achieve an optical focus function; the photosensitive component 30 is disposed in the chip anti-shake portion 24, which is configured to drive the photosensitive component 30 to move to achieve an optical anti-shake function. The driving device 20 includes an object side, an image side, and a first side 101, a second side 102, a third side 103, and a fourth side 104 surrounding the driving device in a clockwise direction.

[0154] In one embodiment of the present application, the driving device 20 further includes a housing 22, wherein the housing 22 is fixed to the photosensitive component 30, and the housing 22 includes a housing body 221, and the housing body 221 includes an annular side wall 2211 and a top 2212. The annular side wall 2211 and the top 2212 form an accommodating cavity, which accommodates the lens focusing part 23, the chip anti-shake part 24 and the base 21. On the one hand, it can prevent dust from entering, and on the other hand, it can prevent the components from falling off during impact.

[0155] In one embodiment of the present application, the driving device 20 further includes a base 21, which is fixedly connected to the housing 22, that is, the base 21 and the housing 22 are both stators. When the camera module 1 performs the optical focus function and the optical image stabilization function, the lens focus part 23 and the chip image stabilization part 24 can be driven to move relative to the base 21. Furthermore, the base 21 is arranged between the lens focus part 23 and the chip image stabilization part 24, that is, the lens focus part 23 is arranged on the object side of the base 21, and the chip image stabilization part 24 is arranged on the image side of the base 21. The base 21 is movably connected to the lens focus part 23 and the chip image stabilization part 24, respectively, so that the lens focus part 23 and the chip image stabilization part 24 can move relative to the base 21.

[0156] Specifically, the base 21 includes an upward extension portion 211, a top lateral extension portion 212, and a bottom lateral extension portion 213. The upward extension portion 211 integrally extends from the bottom lateral extension portion 213 along the optical axis toward the object side. In a specific example of the present application, there are four upward extension portions 211, which are respectively arranged at the four corners of the bottom lateral extension portion 213, including a first upward extension portion 2111, a second upward extension portion 2112, a third upward extension portion 2113, and a fourth upward extension portion 2114.

[0157] The bottom side lateral extension portion 213 extends in the horizontal direction and is a horizontal hollow ring. In a specific example of the present application, the bottom side lateral extension portion 213 is located on three sides of the base 21, and one side of the base 21 is not provided with the bottom side lateral extension portion 213, that is, the base 21 has an opening, and the opening faces the side where the bottom side lateral extension portion 213 is not provided.

[0158] The top lateral extension 212 extends horizontally from the upward extension 211 and connects two adjacent upward extensions 211. The top lateral extension 212 is higher than the bottom lateral extension 213. In a specific example of the present application, there is one top lateral extension 212, which is disposed on the side of the base 21 where the bottom lateral extension 213 is not disposed, that is, the top lateral extension 212 is disposed on the side where the opening of the base 21 is located. In other words, the top lateral extension 212 and the bottom lateral extension 213 are disposed on opposite sides. In a specific example of the present application, the top lateral extension 212 is disposed on the first side 101, and the bottom lateral extension 213 is disposed on the third side 103 opposite the first side 101.

[0159] Furthermore, the base 21 also includes a mounting portion 214 for a focusing magnet 2321, which is disposed on a side wall of the base 21. The two adjacent upwardly extending portions 211 and the top lateral extending portion 212 constitute the mounting portion 214 for the focusing magnet 2321. For example, in a specific example of the present application, the first upwardly extending portion 2111, the second upwardly extending portion 2112, and the top lateral extending portion 212 located on the first side 101 constitute the mounting portion 214 for the focusing magnet 2321.

[0160] As shown in Figures 4 to 7, in one embodiment of the present application, the lens focusing part 23 includes a focusing movable part 231, a focusing driving part 232 and a focusing conductive part 233, wherein the lens is coupled to the focusing movable part 231, the focusing conductive part 233 provides driving power for the lens focusing part 23, and the focusing driving part 232 drives the focusing movable part 231 to move relative to the base 21, thereby driving the optical lens 10 to move along the optical axis direction to realize the optical focusing function.

[0161] Furthermore, the lens focusing portion 23 is disposed on the object side of the base 21, and the chip anti-shake portion 24 is disposed on the image side of the base 21, so that the optical lens 10 is disposed on the light-sensing path of the photosensitive component 30. The base 21 remains stationary, and when the focus movable portion 231 is driven to move relative to the base 21, the focus movable portion 231 can drive the optical lens 10 to move relative to the photosensitive component 30 along the optical axis, thereby realizing the optical focus function of the camera module 1.

[0162] In one embodiment of the present application, a movable focus portion 231 is disposed on the object side of the base 21. The movable focus portion 231 has a peripheral side located between the object side and the image side of the movable focus portion 231. The peripheral side of the movable focus portion 231 includes a first side 101, a second side 102, a third side 103, and a fourth side 104 arranged in a clockwise direction. The movable focus portion 231 includes a focus carrier 2311. A receiving space is formed between the base 21 and the housing 22. The focus carrier 2311 is received in the receiving space and is movable relative to the housing 22 and the base 21. The focus carrier 2311 has a mounting cavity 23111 in its central portion. The optical lens 10 is disposed in the mounting cavity 23111 so that the optical lens 10 can move with the movement of the focus carrier 2311. Furthermore, there is a certain gap between the focusing carrier 2311 and the outer shell 22 and the base 21 so that no interference occurs when the focusing carrier 2311 moves relative to the outer shell 22 and the base 21 .

[0163] Furthermore, the focusing carrier 2311 further includes an anti-collision boss 23112, which is respectively arranged at the object side end and the image side end of the focusing carrier 2311, so that the focusing carrier 2311 will not directly collide with the base 21 and the outer shell 22 when moving along the optical axis, thereby avoiding damage to the optical lens 10 arranged on the focusing carrier 2311 due to collision.

[0164] The focusing carrier 2311 further includes a focusing coil 2322 mounting portion 23113 , which is located on a side wall of the focusing carrier 2311 . The focusing coil 2322 mounting portion 23113 is arranged opposite to the focusing magnet 2321 mounting portion 214 .

[0165] In one embodiment of the present application, a focus drive unit 232 is disposed between the focus movable unit 231 and the base 21, and the focus drive unit 232 is capable of driving the focus movable unit 231 to move relative to the base 21 along the optical axis. The focus drive unit 232 includes a focus coil 2322 and a focus magnet 2321. The focus magnet 2321 and the focus coil 2322 are disposed opposite each other. The focus magnet 2321 is disposed on the base 21, and the focus coil 2322 is disposed on the focus movable unit 231. In a specific example of the present application, the focus coil 2322 is disposed on the focus coil 2322 mounting portion 23113 of the focus carrier 2311, and the focus magnet 2321 is disposed on the focus magnet 2321 mounting portion 214 of the base 21, so that the focus magnet 2321 and the focus coil 2322 are disposed opposite each other along the optical axis. When the focusing coil 2322 is energized, the magnetic field generated interacts with the magnetic field of the focusing magnet 2321, and the generated driving force drives the focusing carrier 2311 to move along the optical axis.

[0166] Specifically, as shown in Figures 4 and 6, in one embodiment of the present application, the number of focusing coils 2322 and focusing magnets 2321 is one, wherein the focusing coil 2322 is a single-sided coil, the focusing coil 2322 is arranged on a side wall of the focusing carrier 2311, and the focusing magnet 2321 is arranged on a side wall of the same side of the base 21 opposite thereto, for example, the focusing coil 2322 is arranged on the focusing coil 2322 mounting portion 23113 of the first side 101 of the focusing carrier 2311, and the focusing magnet 2321 is arranged on the focusing magnet 2321 mounting portion 214 of the first side 101 of the base 21, that is, the focusing drive portion 232 is only arranged on one side of the drive device 20, for example, the first side 101, the second side 102, the third side 103 or the fourth side 104, so as to reduce the lateral size of the drive device 20.

[0167] More specifically, in one embodiment of the present application, the focusing magnet 2321 extends along the optical axis to the chip anti-shake part 24, that is, the focusing magnet 2321 passes through the lens focusing part 23 and the chip anti-shake part 24 along the optical axis, and the focusing magnet 2321 can participate in the work when realizing the optical focusing and optical anti-shake functions.

[0168] In one embodiment of the present application, the focusing conductive portion 233 is disposed between the focusing carrier 2311 and the base 21, and is coupled to the focusing carrier 2311 and the base 21, respectively. The focusing conductive portion 233 includes a focusing circuit board 2331 and a conductive terminal 2332. The base 21 further includes a conductive element (not shown). The focusing circuit board 2331 is electrically connected to the focusing coil 2322 and the conductive element of the base 21. The conductive terminal 2332 is electrically connected to the conductive element of the base 21 and the circuit board assembly 32 of the photosensitive component 30 to achieve circuit conduction of the lens focusing portion 23. It is understandable that the conductive element of the base 21 can be disposed on the surface of the base 21, or can be integrally formed on the base 21 using an insert injection molding process. This application does not impose any restrictions on this.

[0169] The focus circuit board 2331 is disposed between the bottom surface of the focus carrier 2311 and the top surface of the base 21. Alternatively, the focus circuit board 2331 can also be disposed on the top surface of the focus carrier 2311 and the top surface of the base 21, so as to achieve circuit conduction between the focus coil 2322 and the conductive elements of the base 21 through the focus circuit board 2331. The conductive terminals 2332 are disposed on the side of the base 21 and extend downward to the photosensitive component 30, so as to achieve circuit conduction between the conductive elements of the base 21 and the circuit board assembly 32 of the photosensitive component 30 through the conductive terminals 2332.

[0170] Specifically, the focusing circuit board 2331 includes a connecting end 23313, an extension end 23311 and a bending end 23312, wherein the number of the connecting ends 23313 is two, and the two connecting ends 23313 are electrically connected to the focusing coil 2322 and the conductive element of the base 21 respectively; the number of the extension ends 23311 is at least two, and at least two extension ends 23311 extend integrally from the two connecting ends 23313 in the horizontal direction. For example, in a specific example of the present application, the extension end 23311 can extend in the X-axis direction, or in the Y-direction, or in both the X-axis direction and the Y-axis direction, so that when the focusing carrier 2311 moves along the optical axis, the focusing circuit board 2331 can also produce a certain deformation accordingly; the number of the bending end 23312 is at least one, and at least one bending end 23312 is arranged between at least two extension ends 23311, so that the focusing circuit board 2331 can produce a larger deformation. Furthermore, the deformation of the focusing circuit board 2331 is greater than the moving stroke of the focusing carrier 2311 .

[0171] It is understandable that the focusing circuit board 2331 is disposed on the side of the focusing carrier 2311 adjacent to the side where the focusing coil 2322 is located to facilitate electrical connection between the focusing circuit board 2331 and the focusing coil 2322. For example, there are two focusing circuit boards 2331, and the two focusing circuit boards 2331 are respectively disposed on opposite sides of the focusing carrier 2311. That is, when the focusing coil 2322 is disposed on the first side 101 of the focusing carrier 2311, the two focusing circuit boards 2331 are respectively disposed on the second side 102 and the fourth side 104 adjacent to the first side 101. The focusing circuit board 2331 can be implemented as a flexible printed circuit (FPC) or a rigid-flexible board.

[0172] As shown in Figures 3 to 6, in one embodiment of the present application, the lens focusing portion 23 further includes a focus holding portion 234, so that the focus carrier 2311 is always maintained in the base 21 during the movement process. Furthermore, the focus holding portion 234 includes a focus magnetic member 2341 and a focus support member 2342. The focus magnetic member 2341 is disposed on one side of the peripheral side of the focus movable portion 231, and the focus support member 2342 is disposed on one side of the peripheral side of the focus movable portion 231. The focus support member 2342 and the focus magnetic member 2341 are disposed on opposite sides of the focus movable portion 231. In a specific example of the present application, a focus magnetic member 2341 is disposed on the focus movable portion 231. The focus magnetic member 2341 is disposed opposite the focus magnet 2321. A horizontal magnetic attraction force is generated between the focus magnetic member 2341 and the focus magnet 2321, causing the focus magnetic member 2341 and the focus magnet 2321 to attract each other horizontally. This ensures that the focus carrier 2311 is always retained within the base 21. Furthermore, the magnetic attraction force allows the focus carrier 2311 to return to its initial position after movement.

[0173] In one embodiment of the present application, the focusing magnetic member 2341 is disposed on a side wall of the focusing carrier 2311, and the focusing magnetic member 2341 is disposed on a side where the focusing magnet 2321 is located, so that the focusing magnetic member 2341 and the focusing magnet 2321 can be disposed relative to each other. For example, the focusing magnet 2321 is disposed on the first side 101, and the focusing magnetic member 2341 is also disposed on the first side 101. The direction of the magnetic attraction generated between the focusing magnetic member 2341 and the focusing magnet 2321 is perpendicular to the optical axis, and the magnetic attraction forces the focusing carrier 2311 to be retained on one side of the base 21. In another specific example of the present application, the direction of the magnetic attraction generated between the focusing magnetic member 2341 and the focusing magnet 2321 is an acute angle with the optical axis, and the component of the magnetic attraction forces in the direction perpendicular to the optical axis retains the focusing carrier 2311 to one side of the base 21.

[0174] Furthermore, the focus magnetic attraction member 2341 and the focus driving unit 232 are arranged on the same side of the lens focus part 23. For example, the focus magnetic attraction member 2341 and the focus driving unit 232 are both arranged on the first side 101 of the lens focus part 23. Specifically, the focus coil 2322 has a side close to the focus magnet 2321 and a side away from the focus magnet 2321. The focus magnetic attraction member 2341 is arranged on the side of the focus coil 2322 away from the focus magnet 2321, and the focus magnetic attraction member 2341 is arranged opposite to the focus magnet 2321. In a specific example of the present application, the focus magnetic attraction member 2341 can be integrally formed on the focus carrier 2311 by an insert injection molding process. Of course, in another specific example of the present application, the focus magnetic attraction member 2341 can also be fixed to the focus carrier 2311 by bonding, welding, etc., and the present application does not limit this.

[0175] In the present application, the focusing magnetic attraction component 2341 can be a component that can be attracted by the focusing magnet 2321, such as a metal such as an iron sheet, or a magnet with an opposite magnetic pole to the focusing magnet 2321.

[0176] Continuing with Figures 3 to 6 , in one embodiment of the present application, a focus support member 2342 is disposed on one side of the circumference of the movable focus portion 231. The focus support member 2342 is disposed between the focus carrier 2311 and the base 21. The focus carrier 2311 is always supported on the base 21 by the focus support member 2342. The focus support member 2342 is clamped between the movable focus portion 231 and the base 21 by the focus magnetic member 2341. The focus support member 2342 includes a first ball mounting portion 23421, a second ball mounting portion 23422, and a focus ball 23423 clamped between the first ball mounting portion 23421 and the second ball mounting portion 23422. The first ball mounting portion 23421 is arranged on a side wall of the focusing carrier 2311, and the second ball mounting portion 23422 is arranged on a side wall of the base 21. The first ball mounting portion 23421 and the second ball mounting portion 23422 are arranged on the same side of the lens focusing part 23, and the focusing ball 23423 is clamped between the first ball mounting portion 23421 and the second ball mounting portion 23422 to improve the stability of the movement of the focusing base 21 during the optical focusing process and improve the imaging quality.

[0177] Specifically, the first ball mounting portion 23421 forms a track along the Z-axis, and the second ball mounting portion 23422 forms a track along the Z-axis. Since the focus ball 23423 is positioned within the track along the Z-axis, its motion trajectory is confined to the track along the Z-axis, allowing it to move within the track, providing support for the movement of the focus carrier 2311. Two focus balls 23423 are respectively positioned within the first and second ball mounting portions 23421, 23422 to accommodate the required travel range of the focus carrier 2311. Furthermore, a baffle is positioned within the second ball mounting portion 23422, separating it into two mounting areas. The two focus balls 23423 are housed in the two mounting areas, preventing them from colliding during movement and potentially tilting the focus carrier 2311.

[0178] More specifically, the number of focus support members 2342 is two, namely, the number of first ball mounting portions 23421 is two, and the number of second ball mounting portions 23422 is two. The two first ball mounting portions 23421 and the two second ball mounting portions 23422 are respectively disposed on the second side 102 and the fourth side 104 of the movable focus portion 231. In a specific example of the present application, the two second ball mounting portions 23422 are respectively disposed on two adjacent upwardly extending portions 211, and the two first ball mounting portions 23421 are disposed opposite thereto on the focus carrier 2311 to provide more stable support for the movement of the focus carrier 2311. For example, in a specific example of the present application, the two second ball mounting portions 23422 are respectively arranged on the third upward extension portion 2113 and the fourth upward extension portion 2114 located on the second side 102 and the fourth side 104, and the two first ball mounting portions 23421 are respectively arranged on the side walls of the focusing carrier 2311 located on the second side 102 and the fourth side 104, and the two second ball mounting portions 23422 are arranged opposite to the two first ball mounting portions 23421.

[0179] In one embodiment of the present application, the focus support member 2342 and the focus driving unit 232 are located on opposite sides of the lens focus portion 23. For example, in a specific example of the present application, the focus driving unit 232 is disposed on the first side 101 of the lens focus portion 23, and the focus support member 2342 is disposed on the second side 102 and the fourth side 104 of the lens focus portion 23. This is because the focus driving unit 232 is only disposed on one side of the lens focus portion 23 in the present application. When the focus driving unit 232 drives the focus carrier 2311 to move, the focus carrier 2311 and the optical lens 10 may tilt. To avoid this problem, the focus support member 2342 is disposed on the opposite side of the focus driving unit 232. The focus support member 2342 provides support for the focus carrier 2311, thereby allowing the focus carrier 2311 and the optical lens 10 to move stably.

[0180] Furthermore, the first ball mounting portion 23421 and the second ball mounting portion 23422 have a certain height difference. When the first ball mounting portion 23421 moves relative to the second ball mounting portion 23422 along the optical axis under the drive of the focus drive portion 232, the focus ball 23423 always remains between the first ball mounting portion 23421 and the second ball mounting portion 23422 and does not fall off. In a specific example of the present application, the height of the second ball mounting portion 23422 is greater than the height of the first ball mounting portion 23421. This not only provides the required travel distance for the first ball mounting portion 23421 and the focus ball 23423, but also ensures that the focus ball 23423 is always maintained between the first ball mounting portion 23421 and the second ball mounting portion 23422 during its movement, preventing it from falling off.

[0181] In one embodiment of the present application, the focus support member 2342 and the focus magnetic member 2341 are arranged on opposite sides of the lens focus portion 23, so that the focus support member 2342 is clamped between the focus carrier 2311 and the base 21 through the force between the focus magnetic member 2341 and the focus magnet 2321. For example, the focus magnetic member 2341 is arranged on the first side 101 of the focus movable part 231, and the focus support member 2342 is arranged on the second side 102 and the fourth side 104 of the focus movable part 231. The focus magnetic member 2341 and the focus driving part 232 are arranged on the same side of the circumference of the focus movable part 231, and the focus support member 2342 and the focus driving part 232 are arranged on opposite sides of the circumference of the focus movable part 231.

[0182] The first ball mounting portion 23421 has an opening facing the focusing magnetic member 2341, and the second ball mounting portion 23422 has an opening facing away from the focusing magnetic member 2341. A horizontal magnetic attraction force is generated between the focusing magnetic member 2341 and the focusing magnet 2321. This magnetic attraction force clamps the focusing ball 23423 between the openings of the first ball mounting portion 23421 and the second ball mounting portion 23422. Alternatively, the first ball mounting portion 23421 on the focusing carrier 2311 is located outside the second ball mounting portion 23422 on the base 21, meaning the distance from the first ball mounting portion 23421 to the optical axis is less than the distance from the second ball mounting portion 23422 to the optical axis. Of course, the distance from the first ball mounting portion 23421 to the focusing magnetic attraction component 2341 is greater than the distance from the second ball mounting portion 23422 to the focusing magnetic attraction component 2341 .

[0183] Among them, the first ball mounting part 23421 has an opening facing the common magnet, and the second ball mounting part 23422 has an opening facing away from the common magnet. The focusing ball 23423 is clamped between the opening of the first ball mounting part 23421 and the opening of the second ball mounting part 23422 under the action of the focusing magnetic attraction component 2341.

[0184] As shown in FIG6 , in one embodiment of the present application, the lens focusing portion 23 further includes a focus sensing unit 235 , which includes a focus sensing element 2351 and a focus sensing magnet 2352 . The focus sensing element 2351 and the focus sensing magnet 2352 are arranged relative to each other, wherein the focus sensing element 2351 is arranged on one of the focus carrier 2311 and the base 21 , and the focus sensing magnet 2352 is arranged on the other of the focus carrier 2311 and the base 21 . When the focus carrier 2311 moves, the relative position of the focus sensing element 2351 and the focus sensing magnet 2352 changes. Based on the strength of the magnetic field of the focus sensing magnet 2352 sensed by the focus sensing element 2351 , the position of the focus carrier 2311 can be determined, and the current of the focus coil 2322 can be adjusted to move the focus carrier 2311 to the desired position. In the present application, the focus sensing element 2351 can be a Hall element, a driver IC, or a TMR.

[0185] In a specific example of the present application, the focus sensing element 2351 is arranged on the base 21, the focus induction magnet 2352 is arranged on the focus carrier 2311, the focus sensing element 2351 is electrically connected to the conductive element of the base 21, and is electrically connected to the circuit board component 32 of the photosensitive component 30 through the conductive terminal 2332 to achieve circuit conduction of the focus sensing element 2351.

[0186] Furthermore, the focus sensing unit 235 and the focus driving unit 232 are disposed on opposite sides of the lens focusing portion 23. For example, the focus sensing unit 235 is disposed on the third side 103 of the lens focusing portion 23, and the focus driving unit 232 is disposed on the first side 101 of the lens focusing portion 23 opposite to the third side 103.

[0187] In a specific example of the present application, two focus support members 2342 are respectively arranged on the left and right sides of the focus sensing part 235, which on the one hand provide stable support for the focus carrier 2311, and on the other hand make the structure of the lens focus part 23 more compact.

[0188] In a specific example of the present application, the focus magnet 2321 and the focus sensing magnet 2352 are disposed on opposite sides to avoid magnetic interference between the focus sensing magnet 2352 and the focus magnet 2321. For example, the focus magnet 2321 and the focus sensing magnet 2352 may be disposed on opposite sides of the lens focus portion 23, or the focus magnet 2321 and the focus sensing magnet 2352 may be disposed on adjacent sides of the lens focus portion 23, and the present application does not impose any limitation thereto.

[0189] As shown in Figures 8 to 10B, in one embodiment of the present application, the chip anti-shake portion 24 includes an anti-shake movable portion 241, an anti-shake driving portion 242, an anti-shake conductive portion 243, and an anti-shake holding portion 244. The photosensitive chip 31 is directly or indirectly fixed to the anti-shake movable portion 241. The anti-shake conductive portion 243 provides driving power for the chip anti-shake portion. The anti-shake driving portion 242 drives the anti-shake movable portion 241 to move relative to the base 21, thereby driving the photosensitive component 30 to move perpendicular to the optical axis, thereby realizing the chip anti-shake function.

[0190] As shown in Figures 7 to 11A, the lens focusing portion 23 is disposed on the object side of the base 21, and the chip anti-shake portion 24 is disposed on the image side of the base 21, so that the optical lens 10 is disposed in the light-sensing path of the photosensitive component 30. The base 21 remains stationary. When the chip anti-shake portion 24 is driven to move relative to the base 21, the anti-shake movable portion 241 can drive the photosensitive chip 31 to move relative to the base 21 in a direction perpendicular to the optical axis, thereby realizing the chip anti-shake function of the camera module 1.

[0191] The anti-shake movable portion 241 includes an anti-shake movable carrier 2411. The anti-shake movable carrier 2411 is in a hollow square ring shape with a through hole in the middle. The through hole forms a light window to allow light passing through the optical lens 10 to enter the photosensitive component 30.

[0192] The movable anti-shake carrier 2411 is located below the base 21 and is movably connected to the base 21, capable of moving relative to the base 21 in a direction perpendicular to the optical axis. The housing 22 is fixedly connected to the base 21. Both the housing 22 and the base 21 serve as stators, forming a housing space between the housing 22 and the base 21. The movable anti-shake carrier 2411 is accommodated within the housing space and is movable relative to the housing 22 and the base 21. A certain gap exists between the movable anti-shake carrier 2411 and the housing 22 and the base 21 to ensure that the movable anti-shake carrier 2411 does not interfere with the housing 22 and the base 21 when moving relative to the housing 22 and the base 21.

[0193] In some embodiments, as shown in FIG11A , the housing 22 includes a housing body 221 and a housing bottom plate 222 . The housing body 221 includes an annular sidewall 2211 and a top 2212 . The top 2212 of the housing body 221 has a through hole for accommodating the optical lens 10 . The top 2212 extends inward from the top of the annular sidewall 2211 . The housing bottom plate 222 is in the shape of an annular sheet and is disposed at the bottom end of the annular sidewall 2211 . The housing bottom plate 222 can be a structural member independent of the housing body 221 and fixed to the housing body 221 . The housing bottom plate 222 is disposed below the movable anti-shake carrier 2411 and has a certain gap therebetween. The housing body 221 and the top 2212 , the base 21 , and the housing bottom plate 222 constitute a housing space, including an upper housing space and a lower housing space. The upper housing space accommodates the lens focusing unit 23. Specifically, the focusing carrier 2311 is located within the upper housing space and is movable along the optical axis relative to the housing 22 and base 21. The lower housing space accommodates the chip anti-shake unit 24. Specifically, the movable anti-shake carrier 2411 is located within the lower housing space and is movable perpendicular to the optical axis relative to the housing 22 and base 21. The housing bottom plate 222 is provided to retain the chip anti-shake unit 24 within the lower housing space, preventing it from falling off during movement of the drive device 20.

[0194] The movable anti-shake carrier 2411 is fixed to the photosensitive component 30. In some embodiments, the outer edge of the lower surface of the movable anti-shake carrier 2411 extends downward to form a ring-shaped support arm, which is fixed to the circuit board of the photosensitive chip 31. In some embodiments, the through hole of the movable anti-shake carrier 2411 can be used to accommodate a portion of the photosensitive component 30.

[0195] In one embodiment of the present application, as shown in Figures 8 to 10B , an anti-shake drive unit 242 is disposed between the anti-shake movable unit 241 and the base 21. The anti-shake movable unit 241 is capable of driving the anti-shake movable unit 241 to move relative to the base 21 in a direction perpendicular to the optical axis. The anti-shake drive unit 242 includes a plurality of anti-shake coils 2421 and a plurality of anti-shake magnets 2422, which are disposed opposite each other. Multiple anti-shake magnets 2422 are arranged on the base 21, the base 21 has an anti-shake magnet mounting part, multiple anti-shake magnets 2422 are arranged on the anti-shake magnet mounting part of the base 21, multiple anti-shake coils 2421 are arranged on the anti-shake movable part 241, multiple anti-shake coils 2421 are arranged on the anti-shake movable carrier 2411, multiple anti-shake magnets 2422 are arranged opposite to the multiple anti-shake coils 2421, when the multiple anti-shake coils 2421 are energized, they generate magnetic field force with the multiple anti-shake magnets 2422, which is used to provide driving force for optical image stabilization, so that the anti-shake movable carrier 2411 moves relative to the base 21 in a direction perpendicular to the optical axis to achieve anti-shake.

[0196] In a specific example of the present application, the anti-shake magnet mounting portion of the base 21 is disposed on the lower surface of the bottom lateral extension portion 213. The plurality of anti-shake magnets 2422 may be four, disposed on four sides, and arranged opposite the plurality of anti-shake coils 2421 to provide anti-shake driving force for the anti-shake movable carrier 2411.

[0197] Multiple anti-shake coils 2421 are disposed on the anti-shake circuit board 2412, and are electrically conductive to the anti-shake circuit board 2412. The multiple anti-shake coils 2421 can be planar annular coils, matching the number of the multiple anti-shake magnets 2422 and arranged one-to-one. They are disposed below the multiple anti-shake magnets 2422, such that the multiple anti-shake coils 2421 are within the magnetic field of the multiple anti-shake magnets 2422. The multiple anti-shake coils 2421 and the anti-shake circuit board 2412 are disposed on the anti-shake movable carrier 2411. In some embodiments, the multiple anti-shake coils 2421 are embedded in the anti-shake circuit board 2412, forming a planar coil.

[0198] In some embodiments, at least one of the multiple anti-shake magnets 2422 extends toward the object side to form a common magnet with the focus magnet 2321. In a specific example of the present application, one of the anti-shake magnets 2422 extends upward and serves as a focus magnet 2321 to form a common magnet. The common magnet runs through the lens focus part 23 and the chip anti-shake part 24 along the optical axis. When realizing the optical focus and optical anti-shake functions, the common magnet can participate in the work. Among them, the focus coil 2322 and the common magnet are arranged relative to each other in the horizontal direction, and the anti-shake coil 2421 and the common magnet are arranged relative to each other in the height direction. The common magnet interacts with the focus coil 2322 and the anti-shake coil 2421 respectively, driving the focus carrier 2311 and the anti-shake movable carrier 2411 to move relative to the base 21.

[0199] In one embodiment of the present application, as shown in FIG10B , a shared magnet is disposed adjacent to and opposite the focus coil 2322. The shared magnet includes upper and lower magnetic poles along the optical axis, the side surfaces of which correspond to the focus coil 2322. This shared magnet provides the magnetic field required for the focus carrier to move along the optical axis, thereby driving the focus carrier 2311 to move up and down along the optical axis, thereby achieving optical focus. An anti-shake coil 2421 is disposed on the movable anti-shake carrier 2411, opposite the shared magnet and other anti-shake magnets. The shared magnet includes inner and outer magnetic poles perpendicular to the optical axis, while the other anti-shake magnets include inner and outer magnetic poles perpendicular to the optical axis. The inner and outer magnetic poles of the shared magnet and the inner and outer magnetic poles of the other anti-shake magnets provide the magnetic field required for the movable anti-shake carrier 2411 to move perpendicular to the optical axis, thereby corresponding to the anti-shake coil 2421 and driving the movable anti-shake carrier 2411 to move perpendicular to the optical axis, thereby achieving optical image stabilization.

[0200] As shown in Figures 9 to 10B , the bottom lateral extension 213 of the base 21 extends horizontally, forming a horizontal hollow ring with four corners. Two corners on one end, close to and facing the focus coil 2322, extend from the bottom lateral extension 213 along the optical axis toward the object side to form a first upward extension 2111 and a second upward extension 2112. Two corners on the other end, away from and facing away from the focus coil 2322, extend from the bottom lateral extension 213 along the optical axis toward the object side to form a third upward extension 2113 and a fourth upward extension 2114. A top lateral extension 212 extends horizontally from the top ends of the first and second upward extensions 2111 and 2112, connecting the first and second upward extensions 2111 and 2112. The top lateral extension 212 is disposed on the first side 101 of the base 21, and the bottom lateral extension 213 is disposed on the third side 103 opposite the first side 101. The top lateral extension 212 is higher than the bottom lateral extension 213. The top lateral extension 212, the first upward extension 2111, and the second upward extension 2112 form a mounting position 214 for a focusing magnet 2321, which is used to accommodate and mount the focusing magnet 2321, such that the focusing magnet 2321 is disposed opposite the focusing coil 2322.

[0201] In some embodiments, the shared magnet is arranged at the mounting position of the focusing magnet 2321, that is, the mounting position of the focusing magnet is also the mounting position of the shared magnet. The shared magnet is a rectangular parallelepiped structure, which is defined as high along the optical axis, the long side in the horizontal direction is defined as long, and the short side is defined as wide. The upper and lower magnetic poles are located on the side surface formed by the length and height, and the extreme end face of the lower magnetic pole is the lower side surface formed by the length and width. The first upward extending portion 2111 and the second upward extending portion 2112 have inner surfaces arranged opposite to each other, and the side surface formed by the width and height of the shared magnet is fixedly connected to the inner surfaces of the first upward extending portion 2111 and the second upward extending portion 2112, and the lower surface of the top lateral extending portion 212 is fixedly connected to the upper surface formed by the length and width of the shared magnet.

[0202] In some embodiments, the bottom lateral extension portion 213 is located on three sides of the base 21, and one side of the base 21 is not provided with the bottom lateral extension portion 213, that is, the base 21 has an opening, and the opening faces the side where the bottom lateral extension portion 213 is not provided. The top lateral extension portion 212 is provided on the side where the bottom lateral extension portion 213 is not provided, that is, the top lateral extension portion 212 is provided on the side where the opening of the base 21 is located. In other words, the top lateral extension portion 212 and the bottom lateral extension portion 213 are provided on opposite sides. The shared magnet is provided on the side where the bottom lateral extension portion 213 is not provided, that is, the shared magnet is provided on the side where the opening of the base 21 is located, and the shared magnet extends downward from the top lateral extension portion 212 and is fixedly installed in the installation position. The other anti-shake magnets 2422 except the common magnet are respectively arranged on the bottom side lateral extension part 213 located on the three sides of the base 21, wherein the lower surface of the bottom side lateral extension part 213 has an anti-shake magnet mounting position, and the other anti-shake magnets 2422 except the common magnet are arranged on the anti-shake magnet mounting position, and together with the common magnet constitute the magnet required for anti-shake, provide an optical anti-shake magnetic field, and are arranged opposite to the anti-shake coil 2421. When the anti-shake coil 2421 is energized, it drives the anti-shake movable carrier 2411 to move in a direction perpendicular to the optical axis.

[0203] Furthermore, as shown in Figures 9 and 10B, the downward extension height of the shared magnet is greater than the height of the first upward extension portion 2111 and the second upward extension portion 2112, that is, the lower surface of the shared magnet is lower than the lower surfaces of the first upward extension portion 2111 and the second upward extension portion 2112, leaving the lower surface of the shared magnet directly exposed. The inner and outer magnetic poles of the shared magnet are arranged in close proximity to the anti-shake coil 2421, providing a sufficient anti-shake magnetic field. On the other hand, the shared magnet extends downward from the top lateral extension portion 212 and is arranged in close proximity to the focus coil 2322. The side dimensions formed in the length-to-height direction cover the focus coil 2322. That is, the upper and lower magnetic poles provide a sufficient optical focus magnetic field to meet the requirements of the single focus magnet 2321 coil providing a sufficiently large focus driving force for the focus carrier 2311, thereby achieving the requirements of the optical lens 10 moving up and down along the optical axis and the movement range.

[0204] Furthermore, the height distance between the shared magnet and its corresponding anti-shake coil 2421 is consistent with the height distance between the other anti-shake magnets 2422 and their corresponding anti-shake coils 2421. To minimize the structure, the anti-shake magnets 2422, other than the shared magnet, are flat rectangular parallelepipeds, smaller in height. They cover the anti-shake coils 2421 in both length and width, providing the magnetic field required for anti-shake. This reduces the height of the base 21, achieving a compact and miniaturized module structure.

[0205] In one embodiment of the present application, the plurality of anti-shake magnets 2422 further include other magnets in addition to the common magnet, wherein the height of the common magnet is higher than that of the other magnets.

[0206] In one embodiment of the present application, the plurality of anti-shake magnets 2422 further include other magnets in addition to the common magnet, and the projected area of ​​the common magnet along the height direction is smaller than the projected area of ​​the other magnets along the height direction.

[0207] The shared magnet is positioned on the side not provided with the bottom lateral extension 213, occupying a certain height and thickness. The other components of the lens focusing portion 23 are positioned on the remaining three sides of the base 21, ensuring a reasonable arrangement of the components. In some embodiments, the focusing conductive portion 233 is positioned between the focusing carrier 2311 and the base 21, coupling to the focusing carrier 2311 and the base 21 respectively. The focusing conductive portion 233 is positioned on the remaining three sides of the base 21 not provided with the shared magnet to avoid interference and ensure a reasonable layout of the circuits.

[0208] As shown in Figure 4, the focusing conductive part 233 includes a focusing circuit board 2331 and a conductive terminal 2332. The focusing circuit board 2331 is electrically connected to the focusing coil 2322 and the conductive element of the base 21. The conductive terminal 2332 is electrically connected to the conductive element of the base 21 and the circuit board assembly 32 of the photosensitive component 30 to achieve circuit conduction of the lens focusing part 23.

[0209] The focus circuit board 2331 is disposed between the bottom surface of the focus carrier 2311 and the top surface of the base 21. Alternatively, the focus circuit board 2331 may be disposed on the top surface of the focus carrier 2311 and the top surface of the base 21, so as to achieve electrical conduction between the focus coil 2322 and the conductive elements of the base 21 through the focus circuit board 2331. Conductive terminals 2332 are disposed on the side of the base 21 not provided with the shared magnet and extend downwardly to the photosensitive assembly 30, so as to achieve electrical conduction between the conductive elements of the base 21 and the circuit board assembly 32 of the photosensitive assembly 30 through the conductive terminals 2332.

[0210] It is understandable that the focusing circuit board 2331 is arranged on the side of the focusing carrier 2311 adjacent to the side where the focusing coil 2322 is located, that is, the focusing circuit board is arranged on the side of the base 21 adjacent to the common magnet, to facilitate the electrical connection between the focusing circuit board 2331 and the focusing coil 2322. For example, there are two focusing circuit boards 2331, and the two focusing circuit boards 2331 are respectively arranged on opposite sides of the focusing carrier 2311, that is, when the focusing coil 2322 is arranged on the first side 101 of the focusing carrier 2311, the two focusing circuit boards 2331 are respectively arranged on the second side 102 and the fourth side 104 adjacent to the first side 101. Among them, the focusing circuit board 2331 can be implemented as a flexible printed circuit (FPC) or a soft-rigid combination board.

[0211] In one embodiment of the present application, the lens focusing portion 23 further includes a focus retaining portion 234 so that the focus carrier 2311 is always maintained in the base 21 during the movement. Furthermore, the focus retaining portion 234 includes a focus magnetic attraction member 2341 and a focus support member 2342, wherein the focus magnetic attraction member 2341 is provided on the focus carrier 2311, and the focus magnetic attraction member 2341 is arranged relative to the common magnet so that a horizontal magnetic attraction force is generated between the focus magnetic attraction member 2341 and the common magnet. On the one hand, the focus carrier 2311 is always maintained in the base 21, and on the other hand, the focus carrier 2311 can return to its initial position after movement through the action of the magnetic attraction force.

[0212] In one embodiment of the present application, a focus support member 2342 is disposed between the focus carrier 2311 and the base 21, and the focus carrier 2311 is always supported on the base 21 via the focus support member 2342. The focus support member 2342 is disposed on one side of the circumference of the focus movable portion 231, wherein the focus support member 2342 and the shared magnet are located on opposite sides of the focus movable portion 231. The focus support member 2342 includes a first ball mounting portion 23421, a second ball mounting portion 23422, and a focus ball 23423 disposed between the first ball mounting portion 23421 and the second ball mounting portion 23422. The first ball mounting portion 23421 is arranged on a side wall of the focusing carrier 2311, the second ball mounting portion 23422 is arranged on a side wall of the base 21, the first ball mounting portion 23421 and the second ball mounting portion 23422 are arranged on the same side of the focusing drive portion 232, and the focusing ball 23423 is clamped between the first ball mounting portion 23421 and the second ball mounting portion 23422 to improve the stability of the movement of the focusing base 21 during the optical focusing process and improve the imaging quality.

[0213] In one embodiment of the present application, as shown in Figures 4 to 6 , the shared magnet and the focus magnetic member 2341 are located on the same side of the focus movable portion 231, while the focus magnetic member 2341 and the focus support member 2342 are located on opposite sides of the focus movable portion 231. This allows the focus support member 2342 to be clamped between the focus movable portion 231 and the base 21 under the magnetic attraction of the shared magnet and the focus magnetic member 2341.

[0214] In one embodiment of the present application, the focus support member 2342 and the focus drive unit 232 are disposed on opposite sides of the lens focus portion 23. The shared magnet is disposed on the side not provided with the bottom-side lateral extension 213, and the focus support member 2342 is disposed on the side of the base 21 not provided with the shared magnet. Furthermore, the focus support member 2342 is disposed on the side facing away from the shared magnet. Specifically, the focus drive unit 232 is disposed on the first side 101 of the lens focus portion 23, and the focus support member 2342 is disposed on the second side 102 and the fourth side 104 of the lens focus portion 23. This is because in the present application, the focus driving unit 232 is only provided on one side of the lens focus part 23. When the focus driving unit 232 drives the focus carrier 2311 to move, the focus carrier 2311 and the optical lens 10 will tilt. In order to avoid this problem, the focus support member 2342 is provided on the opposite side of the focus driving unit 232, and the focus support member 2342 provides support for the focus carrier 2311, so that the focus carrier 2311 and the optical lens 10 can move stably.

[0215] In some embodiments, the first ball mounting portion 23421 has an opening facing the common magnet, and the second ball mounting portion 23422 has an opening facing away from the common magnet. A horizontal magnetic attraction force is generated between the focusing magnetic attraction member 2341 and the focusing magnet 2321. Under the action of the magnetic attraction force, the focusing ball 23423 is clamped between the opening of the first ball mounting portion 23421 and the opening of the second ball mounting portion 23422. In other words, the first ball mounting portion 23421 on the focusing carrier 2311 is located outside the second ball mounting portion 23422 on the base 21, that is, the distance between the first ball mounting portion 23421 and the optical axis is less than the distance between the second ball mounting portion 23422 and the optical axis.

[0216] In one embodiment of the present application, as shown in Figure 6, the lens focusing part 23 further includes a focus sensing part 235, and the focus sensing part 235 includes a focus sensing element 2351 and a focus sensing magnet 2352. The focus sensing element 2351 and the focus sensing magnet 2352 are arranged relative to each other, wherein the focus sensing element 2351 is arranged in one of the focus carrier 2311 and the base 21, and the focus sensing magnet 2352 is arranged in the other of the focus carrier 2311 and the base 21. When the focus carrier 2311 moves, the relative position of the focus sensing element 2351 and the focus sensing magnet 2352 changes. According to the strength of the magnetic field of the focus sensing magnet 2352 sensed by the focus sensing element 2351, the position of the focus carrier 2311 can be determined, and then the current of the focus coil 2322 is adjusted to move the focus carrier 2311 to the required position. In some embodiments, the focus sensing magnet 2352 and the common magnet are arranged on opposite sides to avoid magnetic interference between the focus sensing magnet 2352 and the focus magnet 2321.

[0217] The anti-shake magnet 2422 is shared with the focus magnet 2321, meaning that the lens focus portion 23 and the chip anti-shake portion 24 share some magnets. This shared magnet not only provides the magnetic field required by the focus coil 2322, working with it to achieve lens focus, but also provides the magnetic field required by the anti-shake coil 2421, working with it to achieve chip anti-shake. This reduces the number of structural components, resulting in a more compact structure and smaller optical components, thereby miniaturizing the drive device 20 and the module structure.

[0218] By installing the common magnet on the mounting position formed by the first upward extension part 2111, the second upward extension part 2112 and the top horizontal extension part 212, the common magnet passes through the lens focusing part 23 and the chip anti-shake part 24 along the optical axis. While providing a sufficiently large focusing magnetic field, the distance from the anti-shake coil 2421 also meets the requirements of providing a sufficient anti-shake magnetic field, so that it only occupies a certain height and thickness in a single direction, reducing the lateral size of the driving device 20, and reserving space for the arrangement of other components in the remaining directions, so as to achieve a reasonable configuration of the focusing and anti-shake components while making full use of the internal structure.

[0219] In a specific example of the present application, as shown in Figures 8 to 11A, the anti-shake conductive portion 243 includes a conductive downward extension and a conductive lateral extension (not shown in the figures). The conductive lateral extension is electrically connected to the anti-shake coil 2421, and the conductive downward extension is electrically connected to the circuit board of the photosensitive chip 31. The anti-shake conductive portion 243 constitutes a part of the anti-shake circuit, connecting the anti-shake circuit board 2412 and the circuit board of the photosensitive chip 31. In some embodiments, the anti-shake conductive portion 243 is disposed within the anti-shake movable carrier 2411 by insert injection molding. The conductive lateral extension is partially exposed on the upper surface of the anti-shake movable carrier 2411 and is electrically connected to the anti-shake coil 2421. The conductive downward extension is disposed within the annular support arm of the anti-shake movable carrier 2411, with the lower surface partially exposed for circuit connection to the chip circuit board 321 of the photosensitive chip 31.

[0220] In a specific example of the present application, as shown in Figures 8 to 11A, a gap exists between the anti-shake coil 2421 and the anti-shake magnet 2422, which are supported and held by an anti-shake retaining portion 244. This means that the anti-shake magnet 2422 and the anti-shake coil 2421 are supported by the anti-shake retaining portion 244 and can move relative to each other. The anti-shake magnet 2422 is disposed on the base 21, and the anti-shake coil 2421 is disposed on the anti-shake movable carrier 2411. A gap exists between the base 21 and the anti-shake movable carrier 2411. The anti-shake movable carrier 2411 is connected to the base 21 via the anti-shake retaining portion 244, allowing the anti-shake movable carrier 2411 to move horizontally relative to the base 21 perpendicular to the optical axis. Furthermore, the anti-shake retaining portion 244 includes an anti-shake magnetic attraction member 2441 and an anti-shake support member 2442. Among them, the anti-shake magnetic component 2441 is arranged on the anti-shake movable carrier 2411, corresponding to the position of the anti-shake magnet 2422, so that a magnetic force parallel to the optical axis is generated between the anti-shake magnetic component 2441 and the anti-shake magnet 2422, so that the anti-shake movable carrier 2411 can return to its initial position after movement.

[0221] In one embodiment of the present application, the anti-shake magnetic attraction component 2441 is arranged on the anti-shake movable carrier 2411, corresponding to the position of the anti-shake magnet 2422. The anti-shake magnetic attraction component 2441 can be a component that generates magnetic attraction with the anti-shake magnet 2422, such as an iron sheet, etc., which is mutually attracted to the anti-shake magnet 2422. In some embodiments, the anti-shake magnetic attraction component 2441 can be integrally formed with the anti-shake movable carrier 2411 through an insert injection molding process. Of course, in another specific example of the present application, the anti-shake magnetic attraction component 2441 can also be fixed to the anti-shake movable carrier 2411 by bonding, welding, etc., and the present application does not limit this.

[0222] The anti-shake support member 2442 is disposed between the base 21 and the movable anti-shake carrier 2411. The anti-shake support member is disposed between the lower surface of the base 21 and the upper surface of the movable anti-shake carrier 2411. The anti-shake support member 2442 includes a ball groove 24421 and anti-shake balls 24422. The ball groove 24421 is disposed on the base 21 or the movable anti-shake carrier 2411 and is used to accommodate the anti-shake balls 24422. The anti-shake balls 24422 support the movable anti-shake carrier 2411 and maintain a certain gap between the base 21.

[0223] In one embodiment of the present application, as shown in Figures 7 and 8, a ball groove 24421 is provided on the movable anti-shake carrier 2411, extending upward from the movable anti-shake carrier 2411. The ball groove 24421 is provided on the outer side of the anti-shake coil 2421 on the movable anti-shake carrier 2411, and is used to accommodate anti-shake balls 24422. There can be four ball grooves 24421, which are symmetrically arranged on the upper surface of the movable anti-shake carrier 2411, and can be arranged at the four corners of the upper surface of the movable anti-shake carrier 2411. A boss corresponding to the ball groove 24421 is formed on the lower surface of the base 21 extending downward. The anti-shake balls 24422 are arranged in the ball groove 24421 and move therein. The anti-shake ball 24422 is accommodated within the ball groove 24421, with one end of the anti-shake ball 24422 contacting the ball groove 24421 and the other end contacting a boss on the lower surface of the base 21. The height of the ball groove 24421 is lower than the diameter of the anti-shake ball 24422, leaving a portion of the anti-shake ball 24422 exposed within the ball groove 24421. Due to the support provided by the anti-shake ball 24422, the movable anti-shake carrier 2411 is movably connected to the base 21 through the anti-shake ball 24422, maintaining a gap between the two. The provision of the boss on the base 21 allows the anti-shake ball 24422 to support and maintain the gap between the movable anti-shake carrier 2411 and the base 21 while reducing the size of the anti-shake ball 24422 and the ball groove 24421. In other embodiments, the ball groove 24421 may also be provided on the base 21.

[0224] The magnetic attraction force between the anti-shake magnetic component 2441 and the anti-shake magnet 2422 is used, on the one hand, to drive the anti-shake movable carrier 2411 to reset, and on the other hand, to put the anti-shake ball 24422 in a clamped state. The anti-shake ball 24422 is always clamped between the anti-shake movable carrier 2411 and the base 21 to prevent the anti-shake ball 24422 from falling off.

[0225] In one embodiment of the present application, as shown in FIG10A , the chip anti-shake portion 24 further includes an anti-shake sensing unit 245. The anti-shake sensing unit 245 includes an anti-shake position sensing element 2451 and an anti-shake position sensing magnet 2452. The anti-shake position sensing element 2451 includes an X-direction sensing element and a Y-direction sensing element. The anti-shake position sensing element 2451 and the anti-shake position sensing magnet 2452 are disposed relative to each other. The anti-shake position sensing element 2451 is disposed on a movable anti-shake carrier 2411, and the anti-shake position sensing magnet 2452 is disposed on the base 21. When the movable anti-shake carrier 2411 moves, the relative position of the anti-shake position sensing element 2451 and the anti-shake position sensing magnet 2452 changes. The position of the movable anti-shake carrier 2411 is determined based on the strength of the magnetic field of the anti-shake position sensing magnet 2452 sensed by the anti-shake position sensing element 2451, and the current of the anti-shake coil 2421 is adjusted to move the movable anti-shake carrier 2411 to the desired position. In some embodiments, the anti-shake position sensing magnet 2452 is shared with the anti-shake magnet 2422 to reduce the number of components. In some embodiments, the anti-shake position sensing element 2451 can be a Hall element, a driver IC, or a TMR.

[0226] Referring to Figures 11A to 13, the camera module 1 also includes a photosensitive component 30, and the optical lens 10 is arranged on the photosensitive path of the photosensitive component 30, so that the photosensitive component 30 can receive the light converged by the optical lens 10 for imaging. In a specific example, the optical lens 10 is fixed to the focusing movable part 231 of the driving device 20, and the photosensitive component 30 is fixed to the anti-shake movable part 241 of the driving device 20, so that the optical lens 10 is maintained on the photosensitive path of the photosensitive component 30. The lens focusing part 23 of the driving device 20 includes a focus movable part 231 movably arranged on the object side of the base 21 and a focus driving part 232 arranged between the focus movable part 231 and the base 31, and the focus driving part 232 is suitable for driving the focus movable part 231 to move relative to the base 21. The driving device 20 is suitable for driving the optical lens 10 to move along the optical axis of the optical lens 10; the lens anti-shake part 24 of the driving device 20 includes an anti-shake movable part 241 and an anti-shake driving part 242, and the anti-shake movable part 241 is movably arranged on the object side of the base 21. It is movably arranged on the image side of the base 21, and the anti-shake movable part 241 includes an anti-shake movable carrier 2411, and the anti-shake driving part 242 is arranged between the anti-shake movable carrier 2411 and the base 21, wherein the chip anti-shake driving part 242 includes an anti-shake magnet 2422 and an anti-shake coil 2421 that are relatively arranged, the anti-shake magnet 2422 is arranged on the base 21, and the anti-shake coil 2421 is arranged on the anti-shake movable carrier 2411, and the driving device 20 is suitable for driving the photosensitive component 30 to move in a plane perpendicular to the optical axis.

[0227] As shown in Figures 11A to 13, the photosensitive component 30 includes a circuit board assembly 32, a photosensitive chip 31 electrically connected to the circuit board assembly 32, and an electronic component 34. The photosensitive chip 31 is used to receive the external light image collected by the optical lens 10 and is electrically connected to the external mobile electronic device through the circuit board assembly 32. In one embodiment of the present application, the electronic component 34 can be one or more of passive electronic components such as resistors and capacitors and active electronic components such as driver chips and memory chips.

[0228] The photosensitive component 30 also includes a filter component 33, which includes a filter element 331. The filter element 331 is held on the photosensitive path of the photosensitive chip 31. The filter element 331 is arranged between the optical lens 10 and the photosensitive chip 31, and is used to filter the incident light entering the photosensitive chip 31, filtering out stray light such as infrared light that is not necessary for imaging. In one embodiment of the present application, the filter element 331 is fixed to the anti-shake movable carrier 2411 of the driving device 20 and corresponds to at least the photosensitive area of ​​the photosensitive chip 31, so that the filter element 331 moves with the movement of the anti-shake movable carrier 2411; in another embodiment of the present application, the filter component 33 also includes a filter element bracket 332. The filter element 331 is installed and fixed to the filter element bracket 332 and corresponds to at least the photosensitive area of ​​the photosensitive chip 31. The filter element bracket 332 has a light hole that passes through the optical lens 10. The incident light from the lens 10 is incident on the photosensitive chip 31 through the light hole. The filter element 331 can be attached to the filter element bracket 332 upright or upside down. Furthermore, the filter element bracket 332 is fixed to the circuit board assembly 32, as shown in Figure 11A or Figure 12A. By setting the filter element bracket 332, the area size of the filter element 331 can be reduced, thereby reducing the cost of the filter assembly 33, and the height of the filter element 331 can be reduced, thereby reducing the risk of collision between the optical lens 10 and the filter element 331 assembly.

[0229] The circuit board assembly 32 includes a chip circuit board 321 and a connecting circuit board 322. The chip circuit board 321 is electrically connected to the connecting circuit board 322, and the photosensitive chip 31 is electrically connected to the chip circuit board 321, so that the photosensitive chip 31 is suitable for being electrically connected to an external mobile electronic device through the connecting circuit board 322. Specifically, the photosensitive chip 31 is fixed to the chip circuit board 321, the filter element bracket 332 is fixed to the chip circuit board 321, and the electronic component 34 is fixed to the chip circuit board 321 and electrically connected to the chip circuit board 321. Furthermore, the chip circuit board 321 is fixed to the anti-shake movable carrier 2411 of the anti-shake movable part 241, and the anti-shake conductive part 243 is electrically conductive with the chip circuit board 321.

[0230] The connecting circuit board 322 includes an inner circuit board 3221, an outer circuit board 3223 and a flexible conductive mechanism 3222 connecting the inner circuit board 3221 and the outer circuit board 3223. The chip circuit board 321 is fixed to the inner circuit board 3221. The chip circuit board 321 is located above the inner circuit board 3221. In one embodiment of the present application, on at least one side of the circuit board assembly 32, the size of the chip circuit board 321 is larger than the size of the inner circuit board 3221, that is, the long side size of the chip circuit board 321 is larger than the long side size of the inner circuit board 3221 and / or the wide side size of the chip circuit board 321 can be larger than the inner circuit board 3221. The wide side size of the circuit board 3221, in other words, the area of ​​the chip circuit board 321 can be larger than the area of ​​the inner circuit board 3221. In the present application, by adding a chip circuit board 321 fixed to the inner circuit board 3221, the inner circuit board 3221 does not need to be directly fixed to the photosensitive chip 31, the electronic component 34 and / or the filter element bracket 332, and the size of the chip circuit board 321 can be larger than the size of the inner circuit board 3221, so that the size of the inner circuit board 3221 can be designed to be smaller, so that the size of the connecting circuit board 322 can be designed to be smaller, and further, the size of the camera module 1 can be designed to be smaller. In a specific example of the present application, electrical conduction between the chip circuit board 321 and the inner circuit board 3221 is achieved by providing an electrical connection medium such as solder paste between the chip circuit board 321 and the inner circuit board 3221.

[0231] In another embodiment of the present application, as shown in Figures 12A and 12B, the chip circuit board 321 has a through hole, and the photosensitive chip 31 is accommodated in the through hole, thereby reducing the overall height of the photosensitive assembly 30. Specifically, the chip circuit board 321 is fixed to the front side of the inner circuit board 3221. Through the through hole, the chip circuit board 321 and the inner circuit board 3221 form a chip accommodating cavity. The photosensitive chip 31 is accommodated in the accommodating cavity and fixed to the inner circuit board 3221. The photosensitive chip 31 is further directly electrically connected to the chip circuit board 321. In other embodiments, the photosensitive chip 31 can also be directly electrically connected to the inner circuit board 3221. In this embodiment, the electronic component 34 is fixed and electrically connected to the chip circuit board 321, and the filter element bracket 332 is fixed to the chip circuit board 321. In this way, the size of the inner circuit board 3221 can be designed to be smaller. In other embodiments of the present application, the electronic component 34 can also be fixed to the inner circuit board 3221 and accommodated in the through hole of the chip circuit board 321, or, part of the electronic component 34 is fixed to the inner circuit board 3221, and part of the electronic component 34 is fixed to the chip circuit board 321.

[0232] Continuing with reference to Figure 13, the flexible conductive mechanism 3222 electrically connects the inner circuit board 3221 and the outer circuit board 3223. The flexible conductive mechanism 3222 is easy to deform. When the inner circuit board 3221 moves relative to the outer circuit board 3223, the inner circuit board 3221 is subject to less resistance. Therefore, when the driving device 20 drives the chip circuit board 321 fixed with the photosensitive chip 31 to move, the resistance generated by the movement of the inner circuit board 3221 fixed to the chip circuit board 321 is less, and thus the driving force of the driving device 20 can be designed to be smaller, thereby reducing the size of the driving device 20.

[0233] In one embodiment of the present application, both outer circuit board 3223 and inner circuit board 3221 have rectangular circumferential shapes when viewed from above. Outer circuit board 3223 has a through hole, which is preferably rectangular and larger than that of inner circuit board 3221. Thus, inner circuit board 3221 and flexible conductive mechanism 3222 are disposed within the through hole. Due to the annular shape of outer circuit board 3223, the area for disposing conductive circuits is reduced. In a specific example of the present application, to maintain a relatively small overall size of circuit board assembly 32, the thickness of outer circuit board 3223 is increased, exceeding that of inner circuit board 3221. This allows for the placement of more layers of conductive circuits within outer circuit board 3223, thereby satisfying the need for disposing electrical conductors within a narrower width. The thickness of outer circuit board 3223 is greater than that of inner circuit board 3221 , so that the bottom surface of inner circuit board 3221 can be positioned higher than the bottom surface of outer circuit board 3223 .

[0234] The connecting circuit board 322 further includes a connecting tape 3224 , which is fixed to one side of the external circuit board 3223 and electrically connected to the external circuit board 3223 . The circuit board assembly 32 is electrically connected to the external mobile electronic device via the connecting tape 3224 .

[0235] The flexible conducting mechanism 3222 includes at least two flexible conducting arms 32221, which extend in the X direction and the Y direction between the inner circuit board 3221 and the outer circuit board 3223 and connect the inner circuit board 3221 and the outer circuit board 3223. The flexible conducting arms 32221 can realize the electrical conduction function by setting electrical wires to electrically connect the inner circuit board 3221 and the outer circuit board 3223. In one embodiment of the present application, the at least two flexible conducting arms 32221 include two flexible conducting arms 32221 disposed on opposite sides of the inner circuit board 3221. Specifically, the flexible conducting mechanism 3222 includes four flexible conducting arms 32221, which are respectively located on four sides of the inner circuit board 3221 and connect the inner circuit board 3221 and the outer circuit board 3223. This ensures that the support provided by the outer circuit board 3223 to the inner circuit board 3221 via the flexible conducting mechanism 3222 is relatively stable and symmetrical. Of course, in the present application, the flexible conducting mechanism 3222 may also include two, three, or more flexible conducting arms 32221, and the present application is not limited thereto.

[0236] In one embodiment of the present application, the flexible conductive arm 32221 may include one or more flexible electrical connectors. When the number of flexible electrical connectors is designed to be large, more conductive circuits can be provided between the inner circuit board 3221 and the outer circuit board 3223. Specifically, the number of flexible electrical connectors in the flexible conductive arm 32221 is determined according to the circuit requirements of the photosensitive chip 31.

[0237] Continuing with reference to Figures 11A and 12A, the outer circuit board 3223 is fixed to the outer shell 22, for example, the outer circuit board 3223 is fixed to the outer shell body 221 or the outer shell bottom plate 222 of the outer shell 22, so that the outer circuit board 3223 is a relatively fixed part in the camera module 1, and the inner circuit board 3221 directly or indirectly fixed to the anti-shake movable carrier 2411 is a relatively movable part. Since the inner circuit board 3221 and the outer circuit board 3223 are connected and electrically conductive through a flexible conductive mechanism 3222 that is easy to deform, the resistance to movement of the inner circuit board 3221 is low. The shell 22 has a accommodating cavity to accommodate the base 21 and the chip anti-shake part 24. The base 21 is fixed to the shell 22, and the external circuit board 3223 is indirectly fixed to the base 21 by being fixed to the shell 22. In other embodiments of the present application, the external circuit board 3223 can also be directly fixed to the base 21, that is, the external circuit board 3223 is fixed to the base 21 including the above-mentioned indirect and direct situations.

[0238] In one embodiment of the present application, the photosensitive component 30 further includes a base 35, the outer circuit board 3223 is fixed to the base 35, and the base 35 is fixed to the housing 22, so that the base 35 and the housing 22 form a relatively closed space, preventing dust and other dirt from entering the photosensitive component 30 through the gap between the inner circuit board 3221 and the outer circuit board 3223. In a specific example, there is an air gap between the inner circuit board 3221 and the base 35, and the inner circuit board 3221 is higher than the outer circuit board 3223, that is, the distance between the bottom surface of the inner circuit board 3221 and the top surface of the base 35 is greater than the distance between the bottom surface of the inner circuit board 3221 and the top surface of the base 35. In this way, when the inner circuit board 3221 moves, no friction occurs between the inner circuit board 3221 and the base 35, thereby reducing the resistance to movement. In this example, the flexible conducting arm 32221 connects the inner circuit board 3221 and the outer circuit board 3223 at an angle, wherein the end of the flexible conducting arm 32221 connected to the inner circuit board 3221 is higher than the end connected to the outer circuit board 3223 .

[0239] In other words, in the present application, the outer circuit board 3223 can be fixed to a relatively fixed part of the driving device 20 (for example, the outer shell 22, the base 35, the base 21 and other components are relatively fixed parts of the driving device 20), and the inner circuit board 3221 is fixed to the anti-shake movable carrier 2411 (the inner circuit board 3221 can be directly fixed to the anti-shake movable carrier 2411, or it can be indirectly fixed to the anti-shake movable carrier 2411 by being fixed to the chip circuit board 321), and the chip anti-shake movable carrier 2411 is held on the base 21 by the anti-shake holding part 244, so that the inner circuit board 3221 can be maintained at a position higher than the outer circuit board 3223, that is, the bottom surface of the inner circuit board 3221 can be higher than the bottom surface of the outer circuit board 3223, so that the inner circuit board 3221 is not easily affected by friction resistance during movement.

[0240] The anti-shake holding part 244 includes an anti-shake magnetic component 2441 arranged on the anti-shake movable carrier 2411 and an anti-shake supporting component 2442 arranged between the base 21 and the anti-shake movable carrier 2411. The magnetic attraction force generated between the anti-shake magnetic component 2441 and the anti-shake magnet 2422 causes the anti-shake movable carrier 2411 to be adsorbed toward the base 21 and causes the anti-shake supporting component 2442 to be clamped by the anti-shake movable carrier 2411 and the base 21. At the same time, the height of the internal circuit board 3221 is maintained by the magnetic attraction between the anti-shake magnetic component 2441 and the anti-shake magnet 2422.

[0241] In one embodiment of the present application, circuit board assembly 32 further includes an inner reinforcing plate 323 secured to the back of inner circuit board 3221 and an outer reinforcing plate 324 secured to the back of outer circuit board 3223 to enhance the structural strength of the connection between circuit board 322. Both inner and outer reinforcing plates 323 and 324 may be made of stainless steel. Outer reinforcing plate 324 is annular and similar in shape to outer circuit board 3223. In this embodiment, an air gap is provided between inner reinforcing plate 323 and base 35. The distance between the bottom surface of inner reinforcing plate 323 and the top surface of base 35 is greater than the distance between the bottom surface of outer reinforcing plate 324 and the top surface of base 35. This prevents friction between inner reinforcing plate 323 and base 35 when inner circuit board 3221 moves, reducing resistance to movement. In this embodiment, inner circuit board 3221 may also be higher than outer circuit board 3223.

Those skilled in the art should understand that the present application is not limited to the above-described embodiments.
