Description

[0002] With the increasing popularity of mobile electronic devices, the technology behind camera modules used in these devices to help users capture images has rapidly developed and progressed. Currently, consumers are demanding increasingly advanced and diverse features in camera modules for mobile devices (e.g., smartphones), such as focus and image stabilization.

[0003] When using a mobile electronic device to shoot objects at different distances, the distance between the optical lens and the photosensitive component is adjusted through a driving device to achieve the focusing function.

[0004] When using mobile electronic devices to take pictures, the physiological tremors of a certain frequency that exist in the human body under normal circumstances and the shaking caused by movement will cause the camera effect to deteriorate. Therefore, mobile electronic devices are usually equipped with anti-shake devices to make the optical lens translate or rotate relative to the photosensitive component to achieve the anti-shake function.

[0100] Exemplary drive device

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.

The carrier body 221 has a through hole suitable for accommodating the optical lens 10. The side extension portion 222 is located above the carrier body 221 (object side). The side extension portion 222 and the carrier body 221 form a space that can accommodate the anti-shake frame 23.

The suspension portion 24 includes a first spring piece 241 and a second spring piece 242, which are spaced apart along the height direction of the driving device 20. The first spring piece 241 is located on the object side of the focus carrier 22, and the second spring piece 242 is located on the image side of the focus carrier 22, so as to repositionably suspend the focus carrier 22 within the anti-shake frame 23.

[0108] Specifically, the first spring piece 241 and the second spring piece 242 have a thin sheet-like structure as a whole. The first spring piece 241 is respectively connected to the top surface of the anti-shake frame 23 and the top surface of the focusing carrier 22, and the second spring piece 242 is respectively connected to the bottom surface of the anti-shake frame 23 and the bottom surface of the focusing carrier 22 to support and limit the movement of the focusing carrier 22, which not only helps to improve the structural stability of the driving device 20, but also enables the focusing carrier 22 to move within a certain range of travel.

[0109] Specifically, in one embodiment of the present application, the suspension portion 24 includes an outer profile fixed to the anti-shake frame 23, an inner profile fixed to the focus carrier 22, and a deformation portion integrally connecting the outer profile and the inner profile. The deformation portion extends from the outer profile to the inner profile in a bent manner so as to reserve sufficient space for the movement of the focus carrier 22. This not only provides a guarantee for the movement stroke of the focus carrier 22, but also reduces the driving resistance of the focus carrier 22 and improves the optical focus sensitivity of the drive device 20. It can be understood that when the length of the deformation portion is longer and the deformation portion is more bent, the deformation of the deformation portion itself is small after the deformation occurs, and it is easier to reset after the deformation portion is stretched. In a specific example of the present application, the deformation portion is an elastic linear structure made of an elastic material (such as rubber, plastic, etc.); in another specific example of the present application, the deformation portion can also be an elastic linear structure made of a rigid material (such as metal, etc.).

[0110] Furthermore, the outer contour of the first spring piece 241 is fixed to the top surface of the anti-shake frame 23, the inner contour of the first spring piece 241 is fixed to the top surface of the focus carrier 22, and the deformed portion of the first spring piece 241 integrally connects the outer contour of the first spring piece 241 and the inner contour of the first spring piece 241. The outer contour of the second spring piece 242 is fixed to the bottom surface of the anti-shake frame 23, the inner contour of the second spring piece 242 is fixed to the bottom surface of the focus carrier 22, and the deformed portion of the second spring piece 242 integrally connects the outer contour of the second spring piece 242 and the inner contour of the second spring piece 242. This arrangement allows the focus carrier 22 to be clamped between the first spring piece 241 and the second spring piece 242, so that the focus carrier 22 is suspended within the anti-shake frame 23.

[0111] More specifically, in one embodiment of the present application, the inner and outer contours of the first spring piece 241 can be fixedly attached to the focus carrier 22 and the anti-shake frame 23 by means of, but not limited to, bonding or hot riveting; the inner and outer contours of the second spring piece 242 can be fixedly attached to the focus carrier 22 and the anti-shake frame 23 by means of, but not limited to, bonding or hot riveting. When the focus carrier 22 is driven to move along the Z-axis, the first and second spring pieces 241, 242 deform to accumulate elastic force. When the focus carrier 22 stops being driven, the accumulated elastic force of the first and second spring pieces 241, 242 is released, thereby driving the focus carrier 22 to return to its original position.

[0112] Furthermore, in one embodiment of the present application, the first spring clip 241 has a split structure, and the second spring clip 242 has an integrated structure. The first spring clip 241 can be used to achieve circuit conduction of the drive device 20; the second spring clip 242 can always maintain good consistency during installation, so that the entire plane of the second spring clip 242 produces less installation tolerance. In another embodiment of the present application, the first spring clip 241 has an integrated structure, and the second spring clip 242 has a split structure. The second spring clip 242 can be used to achieve circuit conduction of the drive device 20; the first spring clip 241 can always maintain good consistency during installation, so that the entire plane of the first spring clip 241 produces less installation tolerance. In another embodiment of the present application, both the first spring clip 241 and the second spring clip 242 have split structures, and both the first spring clip 241 and the second spring clip 242 can be used to achieve circuit conduction of the drive device 20. In another embodiment of the present application, the first spring clip 241 and the second spring clip 242 both have an integrated structure, and the first spring clip 241 and the second spring clip 242 can always maintain good consistency during the installation process, so that the entire plane of the first spring clip 241 and the second spring clip 242 produces less installation tolerance.

[0113] As shown in Figures 2 and 3, in one embodiment of the present application, a first spring piece 241 connects the focus carrier 22 and the anti-shake frame 23 so that the focus carrier 22 is suspended in the anti-shake frame 23. The first spring piece 241 includes a first portion 2411, a second portion 2412, a third portion 2413, and a fourth portion 2414, which are arranged in a counterclockwise direction. The first portion 2411, the second portion 2412, the third portion 2413, and the fourth portion 2414 are respectively connected to the four corners of the focus carrier 22 and the anti-shake frame 23 to provide more stable support for the focus carrier 22 and also provide symmetrical restoring force for the focus carrier 22.

[0114] Specifically, in one embodiment of the present application, the first portion 2411, the second portion 2412, the third portion 2413, and the fourth portion 2414 are arranged axially symmetrically with respect to the X-axis or the Y-axis, that is, the first spring piece 241 is an axisymmetric structure. In other words, the first portion 2411, the second portion 2412, the fourth portion 2414, and the third portion 2413 are symmetrically arranged on both sides. When the focus carrier 22 moves along the Z-axis, the axisymmetric first spring piece 241 can suppress the focus carrier 22 from rotating about the Z-axis. Furthermore, the axisymmetric first spring piece 241 can further improve the flatness of the first spring piece 241, thereby reducing the tilt tolerance of the drive device 20 and improving the assembly accuracy of the drive device 20.

[0115] With further reference to Figures 4, 9, and 10, the support portion 201 is disposed between the anti-shake frame 23 and the fixed portion 21, with the anti-shake frame 23 supported on the fixed portion 21 by the support portion 201. Specifically, the support portion 201 is disposed between the anti-shake frame 23 and the base 212, with the anti-shake frame 23 supported on the base 212 by the support portion 201. This prevents friction between the anti-shake frame 23 and the base 212 when the anti-shake frame 23 moves relative to the base 212, and the anti-shake frame 23 is movably supported on the base 212. In one specific example, the support portion 201 provides an air gap of a fixed size between the anti-shake frame 23 and the base 212, thereby reducing friction that may be generated when the anti-shake frame 23 moves relative to the base 212.

[0116] During the movement of the anti-shake frame 23 relative to the base 212, the support portion 201 can consistently support the anti-shake frame 23, ensuring smooth movement. Specifically, the support portion 201 includes at least three ball bearings 2011, which are clamped between the top surface of the base 212 and the bottom surface of the anti-shake frame 23 and move along the X-axis and Y-axis directions. In a specific example of the present application, the base 212 includes a lower ball bearing track 2122, and the anti-shake frame 23 includes an upper ball bearing track 232. The upper ball bearing track 232 is located on the bottom surface of the anti-shake frame 23, while the lower ball bearing track 2122 is located on the top surface of the base 212. The position of the upper ball bearing track 232 corresponds to the position of the lower ball bearing track 2122, and the upper ball bearing track 232 and the lower ball bearing track 2122 extend perpendicularly to each other, forming a cross shape. In other embodiments of the present application, the upper ball track 232 and the lower ball track 2122 may also be groove structures, and the balls 2011 move in the horizontal direction in the grooves.

[0117] Specifically, the balls 2011 are accommodated between the upper ball track 232 and the lower ball track 2122 and are allowed to move along the upper ball track 232 and the lower ball track 2122. In this way, the balls 2011 are movably held between the base 212 and the anti-shake frame 23, thereby constantly supporting the anti-shake frame 23. Furthermore, when the anti-shake frame 23 is driven to move relative to the base 212, the balls 2011 move between the upper ball track 232 and the lower ball track 2122 in the shape of a cross without causing interference.

[0118] More specifically, there are at least three upper ball bearing tracks 232 and at least three lower ball bearing tracks 2122, each located at the corners of the base 212 and the anti-shake frame 23. In one specific example of the present application, there are four upper ball bearing tracks 232 and four lower ball bearing tracks 2122, each located at the four corners of the base 212 and the anti-shake frame 23. There are four balls 2011, each located between the four upper ball bearing tracks 232 and the four lower ball bearing tracks 2122, to provide more stable support for the anti-shake frame 23.

[0119] As shown in Figures 1 to 7, a magnet 25 is mounted on the anti-shake frame 23, a focus coil 26 is mounted on the focus carrier 22 and faces the magnet 25, and an anti-shake coil 27 is mounted on the base 212 of the fixed portion 21 and faces the magnet 25. When energized by an electric current, the focus coil 26 generates a magnetic field that interacts with the magnetic field of the magnet 25, driving the focus coil 26 and causing it to move along the Z-axis. The focus carrier 22 moves with it, thereby achieving the focusing function. When energized by an electric current, the anti-shake coil 27 generates a magnetic field that interacts with the magnetic field of the magnet 25, driving the magnet 25 and causing it to move along the X-axis and / or Y-axis. The anti-shake frame 23 moves with the magnet 25, and the focus carrier 22, suspended from the anti-shake frame 23, moves with it, thereby achieving the anti-shake function. In the embodiment of the present application, the magnet portion 25 is reused. The magnet portion 25 is used to interact with the focus coil portion 26 in the process of realizing the focusing function, and is also used to interact with the anti-shake coil portion 27 in the process of realizing the anti-shake function, so that the structural design of the driving device 20 is intensive and miniaturized.

[0120] In one embodiment of the present application, the magnet portion 25 is fixed to the anti-shake frame 23, the focus coil portion 26 is fixed to the side of the focus carrier 22, and the anti-shake coil portion 27 is fixed to the top surface of the base 212. The side of the magnet portion 25 facing the focus coil portion 26 is exposed and not covered by the anti-shake frame 23. This allows the distance between the focus coil portion 26 and the magnet portion 25 to be designed to be small, thereby reducing the lateral dimension (horizontal dimension) of the driving device 20. The bottom surface of the magnet portion 25 facing the anti-shake coil portion 27 is exposed. This allows the distance between the anti-shake coil portion 27 and the magnet portion 25 to be designed to be small, thereby reducing the height dimension (Z-axis dimension) of the driving device 20.

[0121] In a specific example, the magnet part 25 includes a first magnet 251, a second magnet 252, and a third magnet 253. The first magnet 251, the second magnet 252, and the third magnet 253 are fixed to the anti-shake frame 23 in a counterclockwise order. The second magnet 252 and the third magnet 253 are disposed oppositely on both sides of the first magnet 251, and the three are arranged in a substantially "匚"-shaped structure.

[0122] The focusing coil part 26 includes a first focusing coil 261 and a second focusing coil 262. The first focusing coil 261 and the second focusing coil 262 are respectively fixed to opposite sides of the focusing carrier 22. Specifically, the first focusing coil 261 is fixed to the focusing carrier 22 and is opposite to the second magnet 252, and the second focusing coil 262 is fixed to the focusing carrier 22 and is opposite to the third magnet 253. Among them, the first focusing coil 261 and the second magnet 252 are disposed oppositely in the horizontal direction, and the second focusing coil 262 and the third magnet 253 are disposed oppositely in the horizontal direction. The first focusing coil 261 and the second focusing coil 262 can both be coil windings. The axis direction of the winding of the first focusing coil 261 and the axis direction of the winding of the second focusing coil 262 are respectively perpendicular to the Z-axis direction (substantially perpendicular to the Z-axis (optical axis) direction), and the axis direction of the winding of the first focusing coil 261 and the axis direction of the winding of the second focusing coil 262 are parallel to each other. Among them, the first focusing coil 261 and the second magnet 252 are disposed oppositely, and the second focusing coil 262 and the third magnet 253 are disposed oppositely. Thus, the first focusing coil 261 and the second focusing coil 262 respectively generate magnetic fields under current excitation and interact with the second magnet 252 and the third magnet 253, thereby driving the focusing coil part 26 and the focusing carrier 22 to move relative to the magnet part 25 and the anti-shake frame 23.

[0123] The anti-shake coil part 27 includes a first anti-shake coil 271, a second anti-shake coil 272, and a third anti-shake coil 273. The first anti-shake coil 271 is fixed to the fixing part 21 and is opposite to the first magnet 251. The second anti-shake coil 272 is fixed to the fixing part 21 and is opposite to the second magnet 252. The third anti-shake coil 273 is fixed to the fixing part 21 and is opposite to the third magnet 253. That is, the first anti-shake coil 271 and the first magnet 251 are arranged opposite to each other in the height direction, the second anti-shake coil 272 and the second magnet 252 are arranged opposite to each other in the height direction, and the third anti-shake coil 273 and the third magnet 253 are arranged opposite to each other in the height direction. Specifically, the first anti-shake coil 271, the second anti-shake coil 272, and the third anti-shake coil 273 are fixed to the top surface of the base 212 in a counterclockwise order. The second anti-shake coil 272 and the third anti-shake coil 273 are arranged on both sides of the first anti-shake coil 271, and the three are arranged in a substantially "匚"-shaped structure. The first anti-shake coil 271, the second anti-shake coil 272, and the third anti-shake coil 273 can all be coil windings. The axis direction of the winding of the first anti-shake coil 271, the axis direction of the winding of the second anti-shake coil 272, and the axis direction of the winding of the third anti-shake coil 273 are respectively parallel to the Z-axis direction (substantially parallel to the Z-axis (optical axis) direction). The axis direction of the winding of the first anti-shake coil 271, the axis direction of the winding of the second anti-shake coil 272, and the axis direction of the winding of the third anti-shake coil 273 are parallel to each other, and the first anti-shake coil 271, the second anti-shake coil 272, and the third anti-shake coil 273 are laid flat on the base 212. Among them, the first anti-shake coil 271 is arranged opposite to the first magnet 251, the second anti-shake coil 272 is arranged opposite to the second magnet 252, and the third anti-shake coil 273 is arranged opposite to the third magnet 253. Thus, the first anti-shake coil 271, the second anti-shake coil 272, and the third anti-shake coil 273 respectively generate magnetic fields under current excitation and interact with the first magnet 251, the second magnet 252, and the third magnet 253, so as to drive the magnet part 25, the anti-shake frame 23, the focus coil part 26, and the focus carrier 22 to move relative to the base 212 of the fixing part 21.

[0124] In this application, the second magnet 252 and the third magnet 253 of the magnet unit 25 are reused. They interact with the focus coil unit 26 during the focus function and with the anti-shake coil unit 27 during the anti-shake function. In one embodiment of this application, the second magnet 252 and the third magnet 253 are multi-pole magnets (quadrupole magnets as shown in FIG6 ). This allows them to simultaneously provide the magnetic fields required by the focus coil unit 26 and the anti-shake coil unit 27. Furthermore, since the first magnet 251 is not used to drive the focus coil unit 26 and the focus carrier 22, its height is smaller than that of the second magnet 252 and the third magnet 253. The top surface of the first magnet 251 is also lower than that of the second magnet 252 and the third magnet 253.

[0125] In one embodiment of the present application, as described above, the magnetic portion 25 includes three magnets: a first magnet 251, a second magnet 252, and a third magnet 253. The magnetic portion 25 is only provided on three sides of the driving device 20. One side of the driving device 20 is not provided with the magnetic portion 25, and no magnet is provided on the side opposite the first magnet 251. In this case, when the driving device 20 in this embodiment is applied to an array module, the camera module of another array module can be provided on the side of the driving device 20 where the magnetic portion 25 is not provided. In this way, the magnetic portion 25 of the driving device 20 will not cause magnetic field interference to the adjacent camera module.

[0126] In another embodiment of the present application, the magnet portion 25 may include only two magnets, a first magnet 251 and a second magnet 252. In this case, the focus coil portion 26 also includes only a first focus coil 261 disposed opposite the second magnet 252, and the anti-shake coil portion 27 includes a first anti-shake coil 271 disposed opposite the first magnet 251 and a second anti-shake coil 272 disposed opposite the second magnet 252. Reducing one magnet (the third magnet 253) can further reduce the size of the drive device 20, but also reduces the driving force of the drive device 20. As a result, when the focus function is implemented, only one side is provided with the first focus coil 261 and the second magnet 252 for driving. Due to the interaction between the first focus coil 261 and the second magnet 252, the focus carrier 22 is prone to tilt relative to the Z-axis (optical axis), ultimately causing blurred images from the camera module 1.

[0127] In another embodiment of the present application, the magnetic portion 25 may further include a fourth magnet, so that magnets are provided on all four sides of the driving device 20, and the magnetic portion 25 includes four magnets. However, when magnets are provided on all four sides of the driving device 20, when the driving device 20 is used in an array module, the coil-magnet pair cannot be set on the side of the camera module adjacent to the driving device 20 and adjacent to the fourth magnet, so as to avoid electromagnetic interference between the fourth magnet pair and the coil-magnet pair of the camera module adjacent to the fourth magnet.

[0128] Continuing to refer to Figures 1 to 3, the driving device 20 also includes a position sensing unit 28 for obtaining position information of the optical lens 10. The position sensing unit 28 can obtain the position information of the optical lens 10 in the Z-axis direction and / or the XY plane (the plane where the X-axis and Y-axis are located) and provide the driving device 20 with position information to adjust the position of the optical lens 10, forming a closed-loop control, thereby accelerating the focusing speed and improving the imaging quality.

[0129] The position sensing unit 28 includes a focus position sensing unit 281, which is disposed on one side of the focus carrier 22 along the height direction (Z-axis direction). The focus position sensing unit 281 includes a focus position sensing element 2811 and a focus position sensing magnet 2813. The focus position sensing element 2811 can be a Hall element, a driver IC, a TMR, or other element capable of sensing a magnetic field. The focus position sensing element 2811 and the focus position sensing magnet 2813 are arranged on one side of the focus carrier 22 along the height direction, the focus position sensing element 2811 is arranged in one of the focus carrier 22 and the anti-shake frame 23, and the focus position sensing magnet 2813 is arranged in the other of the focus carrier 22 and the anti-shake frame 23. The focus position sensing element 2811 and the focus position sensing magnet 2813 are arranged opposite to each other along the height direction, and the focus position sensing element 2811 is arranged in the magnetic field of the focus position sensing magnet 2813, so that the focus position sensing element 2811 obtains the position information of the focus position sensing element 2811 relative to the focus position sensing magnet 2813 or obtains the position information of the focus position sensing magnet 2813 relative to the focus position sensing element 2811 by sensing the magnetic field information of the focus position sensing magnet 2813.

[0130] In the present application, the focus position sensing magnet 2813 cannot be replaced by the first magnet 251, the second magnet 252 or the third magnet 253 in the magnet part 25. When the focus position sensing element 2811 is directly facing the first magnet 251, the second magnet 252 or the third magnet 253 in the height direction, the magnetic field directions of the first magnet 251, the second magnet 252 and the third magnet 253 are difficult to meet the working requirements of the focus position sensing element 2811. The detailed reasons are further explained below.

[0131] In one embodiment of the present application, the focus position sensing element 2811 is fixed to the side extension portion 222 of the focus carrier 22, the focus position sensing magnet 2813 is fixed to the top of the anti-shake frame 23, and the focus position sensing element 2811 is located above the focus position sensing magnet 2813, so that the focus position sensing element 2811 and the focus position sensing magnet 2813 are arranged on one side of the focus carrier 22 along the height direction, the focus position sensing element 2811 is arranged above the side extension portion 222, and the focus position sensing magnet 2813 is arranged below the side extension portion 222. When the focusing carrier 22 is driven by the focusing coil portion 26 and the magnet portion 25 to move in the height direction (Z-axis direction), the focusing position sensing element 2811 moves in the height direction relative to the focusing position sensing magnet 2813, and the focusing position sensing element 2811 moves away from or close to the focusing position sensing magnet 2813 in the Z-axis direction. The focusing position sensing element 2811 senses the change in the magnetic field of the focusing position sensing magnet 2813, and then obtains the change in position information of the focusing position sensing element 2811 and the focusing carrier 22.

[0132] In one embodiment of the present application, the projection of the focus position sensing element 2811 along the height direction at least partially falls within the focus position sensing magnet 2813. In a specific example, the projection of the focus position sensing element 2811 along the height direction falls within the focus position sensing magnet 2813, so that the focus position sensing element 2811 can obtain stronger magnetic field information.

[0133] The focus position sensing unit 281 further includes a focus circuit board 2812 that provides a conducting circuit for the focus position sensing element 2811 . The focus position sensing element 2811 is electrically connected to the focus circuit board 2812 . The focus circuit board 2812 is fixed to the side extension portion 222 of the focus carrier 22 . In a specific example of the present application, the focus circuit board 2812 is fixed above the side extension portion 222 (in the object side direction), and the focus position sensing element 2811 is fixed above the focus circuit board 2812, so that the focus position sensing element 2811 is fixed above the side extension portion 222, and the focus position sensing magnet 2813 is located below the focus position sensing element 2811 and is fixed to the top of the anti-shake frame 23, so that the distance between the focus position sensing element 2811 and the focus position sensing magnet 2813 can be designed to be larger. When the focus carrier 22 is driven by the focus coil portion 26 and the magnet portion 25 to move in the height direction, the focus position sensing element 2811 moves away from or close to the focus position sensing magnet 2813. In another specific example of the present application, the focus position sensing element 2811 can be fixed below the focus circuit board 2812, so that the focus position sensing element 2811 is fixed below the side extension 222, and the focus position sensing magnet 2813 is located below the focus position sensing element 2811 and is fixed to the top of the anti-shake frame 23, so that the focus position sensing element 2811 can be closer to the focus position sensing magnet 2813, and the position sensing magnet can provide the focus position sensing element 2811 with stronger magnetic field information.

[0134] As shown in Figures 3 and 7, the focusing carrier 22 also includes a focusing conductive component 223 fixed to the carrier body 221. The focusing conductive component 223 includes a first focusing conductive part 2231 and a second focusing conductive part 2232. The first focusing conductive part 2231 and the second focusing conductive part 2232 are embedded in the carrier body 221 by, for example, insert molding. The focusing conductive component 223 is electrically connected to the focusing circuit board 2812 and the focusing coil part 26. Specifically, the first focusing conductive member 2231 is electrically connected to the focusing circuit board 2812 and the first focusing coil 261, and the second focusing conductive member 2232 is electrically connected to the focusing circuit board 2812 and the second focusing coil 262, so that the focusing position sensing element 2811 and the first focusing coil 261 and the second focusing coil 262 of the focusing coil portion 26 are electrically connected, the first focusing coil 261 and the second focusing coil 262 are connected in series through leads, and the first focusing coil 261 is electrically connected to the second focusing coil 262, so that the focusing position sensing element 2811 can adjust the current direction and / or current magnitude of the first focusing coil 261 and the second focusing coil 262 of the focusing coil portion 26.

[0135] 3 , the focus position sensing element 2811 is disposed between the first portion 2411 and the fourth portion 2414. The first portion 2411, second portion 2412, third portion 2413, and fourth portion 2414 of the first spring 241 are electrically connected to the focus circuit board 2812, thereby providing circuit conduction for the focus circuit board 2812. The focus position sensing element 2811 is electrically connected to the focus circuit board 2812. The first portion 2411, second portion 241, fourth portion 2414, and third portion 2413 are located on either side of the focus position sensing element 2811 and are electrically connected to the focus circuit board 2812. The first portion 2411, second portion 2412, third portion 2413, and fourth portion 2414 are not connected to each other to avoid circuit shorting.

[0136] In one embodiment of the present application, the focus position sensing portion 281 and the first magnet 251 are located on the same side of the focus carrier 22, and the focus position sensing portion 281 is arranged above the first magnet 251, so that at least one side of the driving device 20 is not provided with a magnet, so that when the driving device 20 in this embodiment is used in the array module, the camera module unit of another array module can be arranged on the side of the driving device 20 where the magnet portion 25 is not provided. In this way, the magnet portion 25 of the driving device 20 will not cause magnetic field interference to the adjacent camera module.

[0137] In one embodiment of the present application, the focus position sensing magnet 2813 is arranged above the first magnet 251. Since the height of the top surface of the first magnet 251 is lower than the top surfaces of the second magnet 252 and the third magnet 253, there is a larger space above the first magnet 251 for setting the focus position sensing magnet 2813, and the height of the driving device 20 can be lowered.

[0138] Since the distance between the focus position sensing magnet 2813 and the first magnet 251 is set relatively close, in order to ensure that both the focus position sensing magnet 2813 and the first magnet 251 can be well fixed to the anti-shake frame 23, the focus position sensing magnet 2813 is implemented as a two-pole magnet, and the first magnet 251 is implemented as a multi-pole magnet. For example, the first magnet 251 can be a four-pole magnet. 6 , viewed from the direction in the figure, the focus position sensing magnet 2813 has an S pole (South Pole) located at the top and an N pole (North Pole) located at the bottom, and the magnetic pole direction (NS) of the focus position sensing magnet 2813 is upward, and the magnetic pole direction of the focus position sensing magnet 2813 is parallel to the height direction, so that the focus position sensing element 2811 can obtain effective magnetic field information; the first magnet 251 includes a first magnetic portion 2511 and a second magnetic portion 2512, and the first magnetic portion 2511 and the second magnetic portion 2512 are stacked in the horizontal direction (perpendicular to the optical axis), and the second magnetic portion 2512 is located on a side of the first magnetic portion 2511 away from the optical axis, and the second magnetic portion 2512 is located on a side of the first magnetic portion 2511 away from the focus carrier 22, and the first magnetic portion 2511 is located between the focus carrier 22 and the second magnetic portion 2512. Viewed from the direction in the figure, The first magnetic portion 2511 has an S pole at its top and an N pole at its bottom. The magnetic pole of the first magnetic portion 2511 is directed upward. The second magnetic portion 2512 has an N pole at its top and an S pole at its bottom. The magnetic pole of the second magnetic portion 2512 is directed downward. Thus, the first magnet 251 has both an N pole and an S pole on the side facing the first anti-shake coil 271. Note that, in this application, the magnetic pole direction (NS) refers to the direction from the N pole toward the S pole.

[0139] In one embodiment of the present application, the magnetic pole direction of the focus position sensing magnet 2813 is the same as the magnetic pole direction of the first magnetic portion 2511 of the first magnet 251. In this way, the focus position sensing magnet 2813 can be arranged on the inner side closer to the focus carrier 22, and the focus position sensing element 2811 is also arranged on the inner side of the focus carrier 22 closer to the optical axis corresponding to the focus position sensing magnet 2813, so that the size of the driving device 20 can be designed to be smaller.

[0140] 6, in one embodiment of the present application, the second magnet 252 includes a third magnetic portion 2521 and a fourth magnetic portion 2522. The third magnetic portion 2521 and the fourth magnetic portion 2522 are stacked in a direction parallel to the optical axis. The third magnetic portion 2521 is located on a side of the fourth magnetic portion 2522 away from the second anti-shake coil 272, and the fourth magnetic portion 2522 is located between the third magnetic portion 2521 and the second anti-shake coil 272. As viewed in the direction of the figure, the third magnetic portion 2521 The left side (the side close to the first focusing coil 261) is the N pole, the right side (the side away from the first focusing coil 261) of the third magnetic part 2521 is the S pole, the left side (the side close to the first focusing coil 261) of the fourth magnetic part 2522 is the S pole, and the right side (the side away from the first focusing coil 261) of the fourth magnetic part 2522 is the N pole. In this way, the side of the second magnet 252 facing the second anti-shake coil 272 has an N pole and an S pole, and the side of the second magnet 252 facing the first focusing coil 261 also has an N pole and an S pole.

[0141] The third magnet 253 includes a fifth magnetic portion 2531 and a sixth magnetic portion 2532. The fifth magnetic portion 2531 and the sixth magnetic portion 2532 are stacked in a direction parallel to the optical axis. The fifth magnetic portion 2531 is located on the side of the sixth magnetic portion 2532 away from the third anti-shake coil 273, and the sixth magnetic portion 2532 is located between the fifth magnetic portion 2531 and the third anti-shake coil 273. As viewed in the figure, the left side of the fifth magnetic portion 2531 (away from the second focus) The right side of the fifth magnetic part 2531 (the side close to the first focusing coil 261) is the N pole, the left side of the sixth magnetic part 2532 (the side away from the first focusing coil 261) is the N pole, and the right side of the sixth magnetic part 2532 (the side close to the first focusing coil 261) is the S pole. In this way, the side of the second magnet 252 facing the second anti-shake coil 272 has an N pole and an S pole, and the side of the second magnet 252 facing the first focusing coil 261 also has an N pole and an S pole.

[0142] In another embodiment of the present application, the magnetic pole direction of the focus position sensing magnet 2813 may also be opposite to the direction shown in Figure 6, and the magnetic pole direction of the focus position sensing magnet 2813 may be downward, that is, the magnetic pole above the focus position sensing magnet 2813 is the N pole, and the magnetic pole below the focus position sensing magnet 2813 is the S pole. Correspondingly, the top of the first magnetic portion 2511 of the first magnet 251 is the N pole, the bottom of the first magnetic portion 2511 of the first magnet 251 is the S pole, the top of the second magnetic portion 2512 of the first magnet 251 is the S pole, and the bottom of the second magnetic portion 2512 of the first magnet 251 is the N pole. The magnetic pole direction of the first magnetic portion 2511 is downward, and the magnetic pole direction of the second magnetic portion 2512 is upward. In other words, the magnetic pole direction of the focus position sensing magnet 2813 is consistent with the magnetic pole direction of the first magnetic portion 2511 located on the inner side of the first magnet 251, so that the focus position sensing magnet 2813 can be set closer to the inner side of the focus carrier 22. Similarly, the magnetic pole directions of the second magnet 252 and the third magnet 253 can also be set oppositely, and the design can be based on the needs.

[0143] In one embodiment of the present application, as shown in Figures 1, 5, and 8, the anti-shake frame 23 includes a frame body 231 and a first magnetic conductive member 233 fixed to the frame body 231. The first magnetic conductive member 233 is disposed between the focus position sensing magnet 2813 and the first magnet 251. The first magnetic conductive member 233 is made of a material having magnetic conductivity, such as stainless steel (SUS430). The first magnetic conductive member 233 reduces the effect of the magnetic field of the first magnet 251 on the focus position sensing element 2811. In a specific example of the present application, the first magnetic conductive member 233 is embedded in the frame body 231 through a process such as insert molding. The focus position sensing magnet 2813 is disposed above the first magnetic conductive member 233, and the first magnet 251 is disposed below the first magnetic conductive member 233. Specifically, the focus position sensing magnet 2813 and the first magnet 251 can also be fixed by the first magnetic conductive member 233. The focus position sensing magnet 2813 is fixed above the first magnetic conductive member 233 by magnetic attraction, and the first magnet 251 is fixed below the first magnetic conductive member 233 by magnetic attraction. The focus position sensing magnet 2813 can be closely attached to the upper surface of the first magnetic conductive member 233, and the first magnet 251 can be closely attached to the lower surface of the first magnetic conductive member 233.

[0144] Continuing with Figures 5 and 8 , the anti-shake frame 23 also includes a second magnetic conductive member 234 and a third magnetic conductive member 235 fixed to the frame body 231. The second magnetic conductive member 234 and the third magnetic conductive member 235 can be embedded in the frame body 231 through a process such as insert molding. The second magnetic conductive member 234 is positioned on the side of the second magnet 252 away from the first focus coil 261, thereby increasing the magnetic field strength on the side of the second magnet 252 facing the first focus coil 261. The third magnetic conductive member 235 is positioned on the side of the third magnet 253 away from the second focus coil 262, thereby increasing the magnetic field strength on the side of the third magnet 253 facing the second focus coil 262. Specifically, the second magnet 252 can also be fixed to the second magnetic conductive part 234 through the magnetic attraction between it and the second magnetic conductive part 234, or the second magnet 252 can be more firmly adsorbed on the frame body 231 through the magnetic attraction between it and the second magnetic conductive part 234; the third magnet 253 can also be fixed to the third magnetic conductive part 235 through the magnetic action between it and the third magnetic conductive part 235, or be more firmly adsorbed on the frame body 231.

[0145] The second magnetic conductive part 234 and the third magnetic conductive part 235 are arranged on both sides of the first magnetic conductive part 233. The second magnetic conductive part 234 and the third magnetic conductive part 235 can be respectively connected to the two ends of the first magnetic conductive part 233. The second magnetic conductive part 234 and the third magnetic conductive part 235 extend integrally from the two ends of the first magnetic conductive part 233, so that the first magnetic conductive part 233, the second magnetic conductive part 234 and the third magnetic conductive part 235 can be fixed in the frame body 231 as a component, simplifying the manufacturing process. In one embodiment of the present application, the anti-shake frame 23 also includes a connecting member 236 connecting the second magnetic conductive member 234 and the third magnetic conductive member 235. The connecting member 236 is fixed to the opposite side of the first magnetic conductive member 233. By setting the connecting member 236, the first magnetic conductive member 233, the second magnetic conductive member 234, the third magnetic conductive member 235 and the connecting member 236 form an annular structure, so that the annular structure is embedded in the frame body 231 through processes such as insert molding, which can enhance the structural strength of the frame body 231, wherein the shape of the annular structure is close to a rectangle.

[0146] In one embodiment of the present application, the frame body 231 includes a first side portion 2311, a second side portion 2312, a third side portion 2313, and a fourth side portion 2314, which are arranged in sequence counterclockwise. The second side portion 2312 and the fourth side portion 2314 are arranged on opposite sides of the first side portion 2311. The third side portion 2313 is on the opposite side of the first side portion 2311. The first side portion 2311, the second side portion 2312, the third side portion 2313, and the fourth side portion 2314 are integrally connected. The top surface of the first side portion 2311 is lower than the top surfaces of the second side portion 2312 and the fourth side portion 2314. The focus position sensing portion 281 includes a focus position sensing element 2811 and a focus position sensing magnet 2813, which are arranged opposite to each other in the height direction. The focus position sensing magnet 2813 is arranged on the first side portion 2311.

[0147] Specifically, as shown in Figures 1, 2, 3, 5, and 8, the first magnet 251 is fixed to the first side portion 2311, the second magnet 252 is fixed to the second side portion 2312, and the third magnet 253 is fixed to the fourth side portion 2314. The top surface of the first magnet 251 is lower than the top surfaces of the second magnet 252 and the third magnet 253. The focus position sensing magnet 2813 is disposed above the first magnet 251. Since the first side portion 2311 has a lower top surface, a certain space is provided above the first side portion 2311 for disposing the focus position sensing magnet 2813 and the focus position sensing element 2811, without causing the height dimension of the driving device 20 to be designed to be larger.

[0148] The first magnetic conductive member 233 is fixed to the first side portion 2311 and thus fixed to the frame body 231, the second magnetic conductive member 234 is fixed to the second side portion 2312 and thus fixed to the frame body 231, the third magnetic conductive member 235 is fixed to the fourth side portion 2314 and thus fixed to the frame body 231, and the connecting member 236 is fixed to the third side portion 2313 and thus fixed to the frame body 231.

[0149] As shown in Figures 1, 2, and 11, in one embodiment of the present application, the position sensing unit 28 further includes an anti-shake position sensing unit 282. The anti-shake position sensing unit 282 is arranged relative to the magnet portion 25 along the height direction. The anti-shake position sensing unit 282 is arranged on the base 212. When the anti-shake frame 23 moves, the relative position of the anti-shake position sensing unit 282 and the magnet portion 25 changes. Based on the strength of the magnetic field of the magnet portion 25 sensed by the anti-shake position sensing unit 282, the position of the anti-shake frame 23 can be determined, and the current of the focus coil portion 26 and the anti-shake coil portion 27 can be adjusted to move the anti-shake frame 23 to the desired position. In the present application, the anti-shake position sensing unit 282 can be a component that can sense a magnetic field, such as a Hall element, a driver IC, or a TMR.

[0150] Specifically, in one embodiment of the present application, the anti-shake position sensing unit 282 includes a first anti-shake position sensing element 2821 and a second anti-shake position sensing element 2822. The first anti-shake position sensing element 2821 is disposed in a height direction opposite to the first magnet 251, and the second anti-shake position sensing element 2822 is disposed in a height direction opposite to the second magnet 252 or the third magnet 253. The first anti-shake position sensing element 2821 and the second position sensing element sense position information of the anti-shake frame 23 along the X-axis and Y-axis directions. For example, in one specific example of the present application, the first anti-shake position sensing element 2821 is disposed within the first anti-shake coil 271 so as to be disposed in a height direction opposite to the first magnet 251, and the second anti-shake position sensing element 2822 is disposed within the third anti-shake coil 273 so as to be disposed in a height direction opposite to the third magnet 253.

[0151] More specifically, in one embodiment of the present application, a groove is provided on the base 212, and the first anti-shake position sensing element 2821 and the second anti-shake position sensing element 2822 are provided in the groove of the base 212 to prevent the first anti-shake position sensing element 2821 and the second anti-shake position sensing element 2822 from protruding from the top surface of the base 212, thereby increasing the height of the driving device 20.

[0152] In one embodiment of the present application, the base 212 includes a base body 2121, a magnetic component 2123 and a base conductive component 2124, wherein the magnetic component 2123 and the base conductive component 2124 are arranged on the base body 2121, and the magnetic component 2123 and the base conductive component 2124 have a certain height difference on the base body 2121 to avoid interference between the two. For example, in a specific example of the present application, the magnetic component 2123 is arranged higher than the base conductive component 2124, which not only prevents interference between the magnetic component 2123 and the base conductive component 2124, but also makes the distance between the magnetic component 2123 and the magnet part 25 closer, thereby having a better magnetic effect. In another specific example of the present application, the magnetic component 2123 can be arranged lower than the base conductive component 2124, and the present application does not impose any restrictions on this.

[0153] More specifically, in one embodiment of the present application, the magnetic assembly 2123 is embedded in the base body 2121 through an insert molding process. The magnetic assembly 2123 is only arranged relative to the second magnet 252 and the third magnet 253 of the magnetic portion 25 in the height direction, so as to generate a magnetic attraction force along the height direction (Z-axis direction) between the magnetic assembly 2123 and the second magnet 252 and the third magnet 253. On the one hand, the magnetic attraction force clamps the support portion 201 between the base body 2121 and the anti-shake frame 23; on the other hand, after the anti-shake frame 23 moves, the magnetic attraction force maintains the anti-shake frame 23 in a certain position, where the position can be the initial position before the anti-shake frame 23 is driven. In another embodiment of the present application, the magnetic assembly 2123 can also be fixed to the base body 2121 by gluing or welding, etc., which is not limited by the present application.

[0154] Of course, it can also be said that the side of the base body 2121 opposite to the second magnet 252 and the third magnet 253 is provided with the magnetic attraction component 2123, and the side of the base body 2121 opposite to the first magnet 251 is not provided with the magnetic attraction component 2123.

[0155] Furthermore, the magnetic component 2123 may not contain magnetism. For example, the magnetic component 2123 may be made of ferrite, or the magnetic component 2123 itself may be a permanent magnet. When the magnetic component 2123 is located in the magnetic field of the second magnet 252 and the third magnet 253, it is acted upon by the magnetic force of the second magnet 252 and the third magnet 253. The magnetic component 2123 forms a mutual attraction with the second magnet 252 and the third magnet 253 to limit the position of the second magnet 252 and the third magnet 253 relative to the magnetic component 2123 (the base body 2121), so that the second magnet 252 and the third magnet 253 will basically not separate from the driving device 20 when they are not acted upon by the focusing coil portion 26.

[0156] As shown in Figures 9 and 10, in one embodiment of the present application, the magnetic attraction component 2123 includes a first magnetic attraction portion 21231 and a second magnetic attraction portion 21232. The first magnetic attraction portion 21231 and the second magnet 252 are arranged relative to each other in the height direction, and the second magnetic attraction portion 21232 and the third magnet 253 are arranged relative to each other in the height direction. The first magnetic attraction portion 21231 and the second magnetic attraction portion 21232 are arranged on opposite sides of the base body 2121, that is, the first magnetic attraction portion 21231 and the second magnetic attraction portion 21232 are arranged relative to each other with respect to the X-axis direction or the Y-axis direction. This arrangement ensures that the first magnetic force F1 generated by the interaction between the first magnetic portion 21231 and the second magnet 252 and the second magnetic force F2 generated by the interaction between the second magnetic portion 21232 and the third magnet 253 are symmetrical. This means that the first magnetic force F1 and the second magnetic force F2 are symmetrical forces. The anti-shake frame 23 maintains balance under the action of the symmetrical magnetic forces (the first magnetic force F1 and the second magnetic force F2) on opposite sides, preventing tilt. Furthermore, in a specific example of the present application, the first magnetic portion 21231 and the second magnetic portion 21232 are symmetrically arranged relative to the X-axis or the Y-axis.

[0157] Furthermore, as mentioned above, a first magnetic attraction force along the height direction is generated between the first magnetic attraction part 21231 of the magnetic attraction component 2123 and the second magnet 252, and a second magnetic attraction force along the height direction is generated between the second magnetic attraction part 21232 of the magnetic attraction component 2123 and the third magnet 253. Under the action of the first magnetic attraction force and the second magnetic attraction force, the ball 2011 always remains clamped between the base body 2121 and the anti-shake frame 23, and the lower ball track 2122 is located on the top surface of the base body 2121. That is to say, the ball 2011 always supports the anti-shake frame 23 through the action of the magnetic attraction force.

[0158] Specifically, the magnetic assembly 2123 is only disposed relative to the second magnet 252 and the third magnet 253 of the magnetic portion 25 along the height direction, and is not disposed relative to the first magnet 251 of the magnetic portion 25 along the height direction. In other words, the magnetic attraction force is only generated between the first magnetic portion 21231 and the second magnet 252, and between the second magnetic portion 21232 and the third magnet 253. In other words, the magnetic assembly 2123 is disposed on the side of the base body 2121 that is opposite to the second magnet 252 and the third magnet 253, and is not disposed on the side of the base body 2121 that is opposite to the first magnet 251. This is because, in this application, the first magnet 251, the second magnet 252, and the third magnet 253 are respectively arranged on three sides of the anti-shake frame 23. When the first magnet 251, the second magnet 252, and the third magnet 253 all generate magnetic attraction with the magnetic assembly 2123, only the three sides of the anti-shake frame 23 are affected by the magnetic attraction, causing the anti-shake frame 23 to tilt under the action of the asymmetric magnetic attraction. To avoid this, only the second magnet 252, the third magnet 253 and the magnetic assembly 2123 generate symmetrical magnetic attraction, so that the anti-shake frame 23 can remain stable under the action of the symmetrical magnetic attraction.

[0159] More specifically, the first magnetic portion 21231 and the second magnetic portion 21232 are only located on opposite sides of the base body 2121 and do not extend to the corners of the base body 2121. This means that the first magnetic portion 21231 and the second magnetic portion 21232 are only attracted by the magnetic force of the second magnet 252 and the third magnet 253, and not by the magnetic force of the first magnet 251, thereby generating an asymmetric magnetic attraction force. Furthermore, the structural arrangement in which the first magnetic portion 21231 and the second magnetic portion 21232 do not extend to the corners of the base body 2121 can also provide a certain placement position for the support portion 201, making the structure of the drive device 20 more compact.

[0160] Furthermore, in one embodiment of the present application, the magnetic assembly 2123 includes an even number of magnetic parts 21233, and the even number of magnetic parts 21233 are symmetrically arranged on opposite sides of the base body 2121 to generate a symmetrical magnetic force. Moreover, the even number of magnetic parts 21233 have the same shape, thereby providing a uniform and stable magnetic force, so that the anti-shake frame 23 is smoothly adsorbed to the base 212. In a specific example of the present application, the number of magnetic parts 21233 is four, the first magnetic part 21231 includes two magnetic parts 21233, the second magnetic part 21232 includes two magnetic parts 21233, and the four magnetic parts 21233 are symmetrically arranged below the second magnet and the third magnet. In another specific example of the present application, the number of magnetic members 21233 is two, the first magnetic portion 21231 includes one magnetic member 21233, the second magnetic portion 21232 includes one magnetic member 21233, and the two magnetic members 21233 are symmetrically arranged below the second magnet and the third magnet.

[0161] In one embodiment of the present application, the magnetic assembly 2123 is a split structure, which includes a first magnetic component 21233a, a second magnetic component 21233b, a third magnetic component 21233c, and a fourth magnetic component 21233d. The first magnetic portion 21231 includes the first magnetic component 21233a and the second magnetic component 21233b, which are symmetrically arranged below the second magnet 252; the second magnetic portion 21232 includes the third magnetic component 21233c and the fourth magnetic component 21233d, which are symmetrically arranged below the third magnet 253. Among them, the first magnetic member 21233a and the second magnetic member 21233b extend along the length direction of the second magnet 252, and the first magnetic member 21233a and the second magnetic member 21233b are arranged at intervals in the length direction of the second magnet 252. The first magnetic member 21233a and the second magnetic member 21233b have a certain interval in the extension direction so that the first magnetic member 21233a and the second magnetic member 21233b do not contact each other, so as to avoid the first magnetic member 21233a and the second magnetic member 21233b being connected as a whole, causing the magnetic attraction force between the first magnetic member 21233a and the second magnet 252 to be too large, thereby affecting the driving of the driving device 20. Effect: The third magnetic component 21233c and the fourth magnetic component 21233d extend along the length direction of the third magnet 253, and the third magnetic component 21233c and the fourth magnetic component 21233d are arranged at intervals in the length direction of the third magnet 253. The third magnetic component 21233c and the fourth magnetic component 21233d have a certain interval in the extension direction so that the third magnetic component 21233c and the fourth magnetic component 21233d do not contact each other. The third magnetic component 21233c and the fourth magnetic component 21233d are connected as a whole, resulting in excessive magnetic attraction between the third magnet 253, thereby affecting the driving effect of the driving device 20.

[0162] Furthermore, the first magnetic member 21233a and the second magnetic member 21233b are separately provided, and are located at opposite ends of the second magnet 252 along the length of the second magnet 252. The third magnetic member 21233c and the fourth magnetic member 21233d are separately provided, and are located at opposite ends of the third magnet 253 along the length of the third magnet 252. The length direction of the second magnet 252 and the third magnet 253 is the X-axis direction, and the width direction of the second magnet 252 and the third magnet 253 is the Y-axis direction. It is understood that below the second magnet 252, the first magnetic member 21233a and the second magnetic member 21233b are symmetrically arranged along the Y-axis; below the third magnet 253, the third magnetic member 21233c and the fourth magnetic member 21233d are symmetrically arranged along the Y-axis; the first magnetic member 21233a and the third magnetic member 21233c are arranged opposite each other along the X-axis; and the second magnetic member 21233b and the fourth magnetic member 21233d are arranged opposite each other along the X-axis. This arrangement allows the second magnet 252 and the third magnet 253 to generate magnetic attraction forces along the X-axis and / or along the Y-axis with the four magnetic members 21233, or in other words, allows the second magnet 252 and the third magnet 253 to generate magnetic attraction forces with component forces along the X-axis and / or along the Y-axis with the four magnetic members 21233.

[0163] When the anti-shake coil portion 27 is not excited by current, the split magnetic assembly 2123 can generate magnetic attraction forces along the X-axis and Y-axis directions (or force components along the X-axis and Y-axis directions) between the first magnetic component 21233a, the second magnetic component 21233b and the second magnet 252, and between the third magnetic component 21233c, the fourth magnetic component 21233d and the third magnet 253. Under the action of these magnetic attraction forces, the anti-shake frame 23 can be maintained at the center position of the driving device 20 (i.e., a position substantially coinciding with the optical axis). In other words, under the action of these magnetic attraction forces, the anti-shake frame 23 can be reset to the center position of the driving device 20.

[0164] In one embodiment of the present application, the upper surface of the magnetic component 21233 is wrapped by the base body 2121, as shown in Figure 10; in other embodiments of the present application, the upper surface of the magnetic component 21233 may also be exposed and not wrapped by the base body 2121, and the present application is not limited to this.

[0165] Continuing with FIG9 , in one embodiment of the present application, the base conductive component 2124 is embedded in the base main body 2121 by, for example, insert molding, to provide a base 212 with a conductive function, so that the anti-shake coil portion 27 and the anti-shake position sensing portion 282 can be electrically connected to the chip circuit board 32 of the photosensitive component 30 through the base conductive component 2124 of the base 212. Furthermore, the base conductive component 2124 is embedded in the base main body 2121 by insert molding, and the base 212 is suitable for providing two flat mounting surfaces for mounting and fixing the anti-shake coil portion 27, the anti-shake position sensing portion 282, and the photosensitive component 30. This not only reduces the number of components of the driving device 20 and the assembly complexity of the driving device 20, but also protects the base conductive component 2124.

[0166] Specifically, in one embodiment of the present application, the magnetic component 2123 and the base conductive component 2124 use different materials, wherein the magnetic component 2123 uses a magnetic conductive material so that the magnetic component 2123 can generate a magnetic attraction force with the second magnet 252 and the third magnet 253 of the magnetic part 25; the base conductive component 2124 uses a non-magnetic conductive material for signal conduction, thereby achieving the advantages of independent function and simplified assembly of the driving device 20. In other words, the base conductive component 2124 cannot generate a magnetic attraction force with the magnetic part 25 and thus be magnetically attracted to each other.

[0167] More specifically, the base conductive component 2124 includes a conductive portion 21241 and a plurality of pins 21242, which are integrally formed from a conductive material. The conductive portion 21241 is embedded in the base body 2121, for example, by insert molding, while the plurality of pins 21242 are exposed and not covered by the base body 2121. The plurality of pins 21242 are electrically connected to the chip circuit board 32 of the photosensitive component 30, thereby electrically connecting the anti-shake coil unit 27, the anti-shake position sensing unit 282, and the chip circuit board 32. It is understood that the number of conductive portions 21241 and the number of pins 21242 are related to the number of circuits required by the anti-shake coil unit 27 and the anti-shake position sensing unit 282, and this application does not impose any restrictions on this.

[0168] As shown in Figures 2, 3, and 11, in one embodiment of the present application, the driving device 20 further includes a side connection portion 29, which is provided on the side walls of the anti-shake frame 23 and the base 212. The side connection portion 29 is generally a thin sheet-like structure, with one end of the side connection portion 29 connected to the side wall of the anti-shake frame 23 and the other end of the side connection portion 29 connected to the side wall of the base 212, thereby supporting and limiting the anti-shake frame 23. This not only helps to improve the structural stability of the driving device 20, but also enables the anti-shake frame 23 to move and reset within a certain range of travel.

[0169] Specifically, in one embodiment of the present application, the side connection portion 29 includes a first connection end fixed to the anti-shake frame 23, a second connection end fixed to the base 212, and an elastically deformable portion integrally connecting the first and second connection ends. The elastically deformable portion includes a plurality of interconnected bent segments extending in the X-direction and a plurality of interconnected bent segments extending in the Y-direction, wherein the plurality of interconnected bent segments extending in the X-direction and the plurality of interconnected bent segments extending in the Y-direction are interconnected. The elastically deformable portion deforms after being stretched in the X- and Y-directions, generating corresponding restoring forces in the X- and Y-directions, causing the anti-shake frame 23 to return to its original position (i.e., the position of the anti-shake frame 23 before movement) under the action of the side connection portion 29.

[0170] More specifically, as shown in Figure 11, in one embodiment of the present application, the side connection portion 29 includes a first side spring clip 291, a second side spring clip 292, a third side spring clip 293, and a fourth side spring clip 294. The first side spring clip 291 and the second side spring clip 292 are disposed on one side of the drive device 20, while the third side spring clip 293 and the fourth side spring clip 294 are disposed on the opposite side of the drive device 20. This ensures that the anti-shake frame 23 is subjected to symmetrical restoring forces after movement. Alternatively, the first side spring clip 291, the second side spring clip 292, the third side spring clip 293, and the fourth side spring clip 294 are symmetrically disposed relative to the X-axis or the Y-axis.

[0171] Furthermore, in one embodiment of the present application, the first connection end of the first side spring clip 291 is electrically connected to the first part 2411 of the first spring clip 241, and the second connection end of the first side spring clip 291 is electrically connected to the base conductive component 2124 of the base 212; the first connection end of the second side spring clip 292 is electrically connected to the second part 2412 of the first spring clip 241, and the second connection end of the second side spring clip 292 is electrically connected to the base conductive component 2124 of the base 212; the first connection end of the third side spring clip 293 is electrically connected to the third part 2413 of the first spring clip 241, and the second connection end of the third side spring clip 293 is electrically connected to the base conductive component 2124 of the base 212; the first connection end of the fourth side spring clip 294 is electrically connected to the fourth part 2414 of the first spring clip 241, and the second connection end of the fourth side spring clip 294 is electrically connected to the base conductive component 2124 of the base 212, so as to achieve circuit conduction of the driving device 20. That is to say, the first spring clip 241 is electrically connected to the focusing circuit board 2812 and the side connection part 29, and the side connection part 29 is electrically connected to the first spring clip 241 and the base conductive component 2124, and the circuit conduction of the driving device 20 is achieved through the first spring clip 241 and the side connection part 29.

[0172] It is understood that the side connection portion 29 can provide a more symmetrical restoring force for the anti-shake frame 23 and also realize the electrical connection of the driving device 20. Furthermore, the side connection portion 29 is provided on the side wall of the driving device 20, and the first elastic piece 241 is provided on the top of the driving device 20, thereby preventing interference or short circuit between the two and thus preventing the driving effect from being affected.

[0173] Array module

[0174] The array module is a multi-camera module including two or more camera module units. For example, the array module may include two camera module units and can be called a dual-camera module, or the array module may include three camera module units and can be called a triple-camera module. In the present application, the array module may also include four, five or more camera module units, but the present application is not limited to this.

[0175] FIG12 shows a schematic top view of the array module 2 of the present application. The array module 2 includes a first camera module 20a and a second camera module 20b. The first camera module 20a includes a first photosensitive component, a first optical lens 22a held on the photosensitive path of the first photosensitive component, and a first driving device 21a for driving the first optical lens 22a to move to achieve optical performance adjustment. The second camera module 20b includes a second photosensitive component, a second optical lens 22b held on the photosensitive path of the second photosensitive component, and a second driving device 21b for driving the second optical lens 22b to move to achieve optical performance adjustment. The first camera module 20a uses the aforementioned driving device 20 of the present application as the first driving device 21a. In other words, the first driving device 21a is implemented as the aforementioned driving device 20 of the present application. The first camera module 20a is the aforementioned camera module 1 equipped with the driving device 20 of the present application.

[0176] In one embodiment of the present application, the array module 2 also includes a module bracket 20c, the first camera module 20a and the second camera module 20b are accommodated in the module bracket 20c and fixed to the module bracket 20c. In a specific example of the present application, the module bracket 20c includes a bracket frame portion 21c and a bracket connecting portion 22c. The bracket connecting portion 22c is integrally connected to the bracket frame portion 21c and divides the bracket frame portion 21c into two module accommodating areas. The first camera module 20a and the second camera module 20b are respectively installed in the two module accommodating areas of the module bracket 20c.

[0177] As shown in Figure 12, the first camera module 20a is adjacent to the second camera module 20b, and the magnet part 25 is not set on the adjacent side of the first camera module 20a and the second camera module 20b. In other words, the first magnet 251 of the magnet part 25 is set on the opposite side of the adjacent side of the driving device 20 (first driving device 21a), and the second magnet 252 and the third magnet 253 are respectively set on the adjacent sides of the adjacent side of the driving device 20.

[0178] The second drive device 21b includes at least one drive magnet 211b and a drive coil disposed opposite the at least one drive magnet 211b. The drive magnet 211b and the drive coil cooperate to drive the second optical lens 22b to move. In one embodiment of the present application, the at least one drive magnet 211b includes a drive magnet 211b disposed on the adjacent side of the second drive device 21b and the drive device 20. Since the magnet portion 25 is not disposed on the adjacent side of the drive device 20, the magnet portion 25 of the drive device 20 generates low or no electromagnetic interference with the drive magnet 211b and the drive coil of the second drive device 21b. The drive magnet 211b of the second drive device 21b also generates low or no electromagnetic interference with the magnet portion 25, the focus coil portion 26, and the anti-shake coil portion 27 of the drive device 20.

[0179] To be suitable for use in the array module 2, with reference to Figures 1 to 11 , the drive device 20 (first drive device 21a) described herein may further have the following characteristics. In one embodiment of the present invention, a connector 236 secured to the third side portion 2313 is disposed on a side of the drive device 20 proximate to the second drive device 21b. The connector 236 may be made of a magnetically permeable material, thereby providing a magnetic barrier and reducing electromagnetic interference between the drive device 20 and the second drive device 21b.

[0180] In one embodiment of the present application, as shown in Figures 3 and 11, since the focus position sensing element 2811 and the focus circuit board 2812 are arranged above the first magnet 251, and the focus position sensing element 2811, the focus circuit board 2812, and the first magnet 251 are located in the extension direction of the first camera module 20a and the second camera module 20b, therefore, in order to enable the first part 2411, the second part 2412, the third part 2413 and the fourth part 2414 of the first spring clip 241 to respectively provide the focus position sensing element 2811 and the focus circuit board 2812 with conductive circuits, the first spring clip 241 is symmetrical about the extension direction of the first camera module 20a and the second camera module 20b, especially the second part 2412 and the third part 2413 are symmetrical about the extension direction of the first camera module 20a and the second camera module 20b, so that the second part 2412 and the third part 2413 can be electrically connected to the focus circuit board 2812.

[0181] Furthermore, the side connection portion 29 is also symmetrical about the direction in which the first camera module 20a and the second camera module 20b extend, such that the first side spring clip 291, the second side spring clip 292, the third side spring clip 293, and the fourth side spring clip 294 of the side connection portion 29 can be electrically connected to the first portion 2411, the second portion 2412, the third portion 2413, and the fourth portion 2414 of the first spring clip, respectively. The first side spring clip 291 and the fourth side spring clip 254 are symmetrical about the direction in which the first camera module 20a and the second camera module 20b extend, while the second side spring clip 292 and the third side spring clip 253 are symmetrical about the direction in which the first camera module 20a and the second camera module 20b extend. Specifically, the first side spring clip 291 and the second side spring clip 292 are disposed on the side of the drive device 20 where the second magnet 252 is disposed, and the third side spring clip 293 and the fourth side spring clip 294 are disposed on the side of the drive device 20 where the third magnet 253 is disposed. The configuration of the side connection portion 29 can also provide sufficient space for the ball 2011 and optimize the spatial structure of the driving device 20 .
