[0113] Furthermore, in one embodiment of the present application, the base 212 includes a base body 2121 and an anti-shake coil mounting area 2122 disposed on the base body 2121. The anti-shake coil mounting area 2122 is disposed on the top surface of the base body 2121, and the anti-shake coil portion 27 is disposed within the anti-shake coil mounting area 2122. The base 212 further includes a base boss 2123, which is integrally disposed on the base body 2121 and extends toward the object side. The base boss 2123 is located near a corner of the base body 2121.

[0114] The housing 211 and base 212 of the fixed portion 21 are both stators. When the driving device 20 drives the optical lens 10 to move, the fixed portion 21 remains relatively fixed, and other components move relative to the fixed portion 21. In one embodiment of the present application, the photosensitive component 30 is fixed to the base 212 of the fixed portion 21, and thus the photosensitive component 30 also becomes a relatively fixed part. The housing 211 and the base 212 each have a light hole to allow imaging light to enter the optical lens 10 fixed to the driving device 20 and to exit the optical lens 10 to enter the photosensitive component 30.

[0115] As shown in Figures 2 to 4, in one embodiment of the present application, the anti-shake frame 23 is movably connected to the base 212 of the fixed part 21, the focusing carrier 22 is movably connected to the anti-shake frame 23, and the optical lens 10 is fixed to the focusing carrier 22, so that when the focusing carrier 22 is driven by the driving device 20, the optical lens 10 moves with the focusing carrier 22.

[0116] In one embodiment of the present application, the focusing carrier 22 includes a carrier body 221, wherein the optical lens 10 is fixed to the carrier body 221, and the carrier body 221 has a through hole suitable for accommodating the optical lens 10, and the optical lens 10 is fixed in the through hole of the focusing carrier 22. Specifically, the optical lens 10 can be fixed to the focusing carrier 22 by, for example, bonding or welding with an adhesive medium, or can be fixed to the focusing carrier 22 by integrally forming the lens barrel of the optical lens 10 and the focusing carrier 22. The present application is not limited thereto.

[0117] The focus carrier 22 is movably arranged on the inner side of the anti-shake frame 23, and the anti-shake frame 23 is movably arranged between the focus carrier 22 and the fixed part 21. In one embodiment of the present application, the anti-shake frame 23 is movably arranged above the base 212, and the anti-shake frame 23 includes a frame body 231, and the frame body 231 has a accommodating cavity 2310. The focus carrier 22 is accommodated in the accommodating cavity 2310 of the anti-shake frame 23.

[0118] It is understood that in the embodiment of the present application, the focus carrier 22 can be driven independently to move relative to the anti-shake frame 23, or it can be driven by the anti-shake frame 23 to move together with the anti-shake frame 23. Furthermore, by driving the focus carrier 22 and / or the anti-shake frame 23 to move, the optical lens 10 is driven to move, thereby achieving the focusing and / or anti-shake functions.

[0119] Specifically, when the anti-shake frame 23 remains stationary and the focusing carrier 22 is driven to move relative to the anti-shake frame 23, the focusing carrier 22 can drive the optical lens 10 to move along the optical axis to achieve the focusing function; when the anti-shake frame 23 is driven to move relative to the base 212, the anti-shake frame 23 can drive the focusing carrier 22 and the optical lens 10 to move in a plane perpendicular to the optical axis to achieve the anti-shake function.

[0120] 2 and 3 , in one embodiment of the present application, the magnet portion 25 , the focus coil portion 26 , and the anti-shake coil portion 27 form a drive assembly of the drive device 20 , which can drive the focus carrier 22 and the anti-shake frame 23 to move.

[0121] The magnet portion 25 is mounted on the anti-shake frame 23, the focus coil portion 26 is mounted on the focus carrier 22 and faces the magnet portion 25, and the anti-shake coil portion 27 is mounted on the base 212 of the fixed portion 21 and faces the magnet portion 25. In a specific example 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. In other words, the focus coil portion 26 and the magnet portion 25 are positioned horizontally opposite each other, while the anti-shake coil portion 27 and the magnet portion 25 are positioned vertically opposite each other.

[0122] In one embodiment of the present application, the focus carrier 22 further includes a focus coil placement location 223 disposed on a sidewall of the carrier body 221, and the focus coil portion 26 is disposed in the focus coil placement location 223. Of course, the focus coil portion 26 can be directly wound around the sidewall of the focus carrier 22, or can be prefabricated and then mounted on the sidewall of the focus carrier 22, and this application does not impose any restrictions on this.

[0123] It can be understood that in the present application, the focusing coil portion 26 can be a hollow surrounding coil, that is, the focusing coil portion 26 is a single coil, which is arranged in a surrounding manner on the side wall of the focusing carrier 22; the focusing coil portion 26 can also be a hollow planar coil, that is, the number of the focusing coil portion 26 is at least one, which is arranged in a planar attachment manner on the side wall of the focusing carrier 22.

[0124] In a specific example of the present application, the focusing coil placement position 223 is formed by a groove that is recessed inwardly on the side wall of the carrier body 221, so that when the focusing coil part 26 is arranged at the focusing coil placement position 223, it will not protrude from the side wall of the carrier body 221, thereby avoiding an increase in the lateral size of the driving device 20.

[0125] Among them, in an embodiment of the present application, the anti-shake frame 23 further includes a magnet placement groove 232, and the magnet part 25 is disposed in the magnet placement groove 232. The magnet placement groove 232 has an opening in the horizontal direction facing the focusing carrier 22 and an opening in the height direction facing the base 212, so that the side and bottom surfaces of the magnet part 25 disposed in the magnet placement groove 232 are exposed.

[0126] Furthermore, the side surface of the magnet part 25 facing the focusing coil part 26 is exposed and not covered by the anti-shake frame 23, so that the distance between the focusing coil part 26 and the magnet part 25 can be designed to be smaller, thereby reducing the lateral dimension (dimension in the horizontal direction) of the driving device 20; the bottom surface of the magnet part 25 facing the anti-shake coil part 27 is exposed, so that the distance between the anti-shake coil part 27 and the magnet part 25 can be designed to be smaller, thereby reducing the height dimension (dimension in the Z-axis direction) of the driving device 20.

[0127] The focusing coil part 26 generates a magnetic field under current excitation and interacts with the magnetic field of the magnet part 25. Then, the focusing coil part 26 is driven, and the focusing coil part 26 moves in the Z-axis direction. The focusing carrier 22 moves with the focusing coil part 26, thereby realizing the focusing function; the anti-shake coil part 27 generates a magnetic field under current excitation and interacts with the magnetic field of the magnet part 25. Then, the magnet part 25 is driven, and the magnet part 25 moves in the X-axis direction and / or Y-axis direction. The anti-shake frame 23 moves with the magnet part 25, and the focusing carrier 22 disposed on the anti-shake frame 23 moves with the anti-shake frame 23, thereby realizing the anti-shake function.

[0128] In the embodiment of the present application, the magnet part 25 is reused. The magnet part 25 is used to interact with the focusing coil part 26 during the process of realizing the focusing function and is also used to interact with the anti-shake coil part 27 during the process of realizing the anti-shake function, making the structural design of the driving device 20 intensive and miniaturized.

[0129] As shown in FIGS. 2 to 6, in an embodiment of the present application, 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 in the magnet placement groove 232 of the anti-shake frame 23 in a counterclockwise order. The second magnet 252 and the third magnet 253 are relatively disposed on both sides of the first magnet 251, and the three are arranged in a substantially "匚" shape structure.

[0130] The focusing coil unit 26 includes a pair of focusing coils 261. The focusing coils 261 surround the side wall of the focusing carrier 22 and are disposed within the focusing coil placement positions 223 provided on the side wall of the focusing carrier 22. The focusing coils 261 are configured to be disposed opposite to the second magnet 252 and the third magnet 253 in the horizontal direction. When the focusing coils 261 are excited by current, magnetic fields are generated and interact with the second magnet 252 and the third magnet 253, thereby driving the relative movement of the focusing coil unit 26 and the focusing carrier 22 with respect to the magnet unit 25 and the anti-shake frame 23.

[0131] The anti-shake coil unit 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 within the anti-shake coil placement position 2122 of the base 212. The first anti-shake coil 271 is disposed opposite to the first magnet 251 in the height direction. The second anti-shake coil 272 is fixed within the anti-shake coil placement position 2122 of the base 212. The second anti-shake coil 272 is disposed opposite to the second magnet 252 in the height direction. The third anti-shake coil 273 is fixed within the anti-shake coil placement position 2122 of the base 212. The third anti-shake coil 273 is disposed opposite to the third magnet 253 in the height direction.

[0132] 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 disposed on both sides of the first anti-shake coil 271, and the three are arranged in a substantially "匚"-shaped structure. Further, the first anti-shake coil 271, the second anti-shake coil 272, and the third anti-shake coil 273 are laid flat on the top surface of the base 212.

[0133] The first anti-shake coil 271 is disposed opposite to the first magnet 251, the second anti-shake coil 272 is disposed opposite to the second magnet 252, and the third anti-shake coil 273 is disposed opposite to the third magnet 253. Thus, when the first anti-shake coil 271, the second anti-shake coil 272, and the third anti-shake coil 273 are excited by current respectively, magnetic fields are generated and interact with the magnetic fields of the first magnet 251, the second magnet 252, and the third magnet 253, thereby driving the relative movement of the magnet unit 25, the anti-shake frame 23, the focusing coil unit 26, and the focusing carrier 22 with respect to the base 212 of the fixed part 21.

[0134] When the anti-shake frame 23 is driven to move horizontally along the X-axis, the second magnet 252 interacts with the second anti-shake coil 272, and the third magnet 253 interacts with the third anti-shake coil 273 to generate a driving force along the X-axis. When the anti-shake frame 23 is driven to move horizontally along the Y-axis, the first magnet 251 interacts with the first anti-shake coil 271 to generate a driving force along the Y-axis. In this application, the length of the first magnet 251 is parallel to the X-axis, and the lengths of the second magnet 252 and the third magnet 253 are parallel to the Y-axis.

[0135] That is, when the anti-shake frame 23 is driven to move horizontally along the X-axis, both the second magnet 252 and the third magnet 253 participate in the operation. However, when the anti-shake frame 23 is driven to move horizontally along the Y-axis, only the first magnet 251 participates in the operation because there is no magnet on the opposite side of the first magnet 251, resulting in a relatively small driving force in this direction. To address this issue, in this application, the first magnet 251 is implemented as a multi-pole magnet to increase the magnetic thrust generated by the interaction between the first magnet 251 and the first anti-shake coil 271. For example, the first magnet 251 can be a quadrupole magnet.

[0136] As shown in Figure 5, in one embodiment of the present application, the first magnet 251 includes a first magnetic part 251a and a second magnetic part 251b. The first magnetic part 251a and the second magnetic part 251b are stacked in the horizontal direction (perpendicular to the optical axis). The second magnetic part 251b is located on the side of the first magnetic part 251a away from the optical axis. The second magnetic part 251b is located on the side of the first magnetic part 251a away from the focusing carrier 22. The first magnetic part 251a is located between the focusing carrier 22 and the second magnetic part 251b. The top of the first magnetic part 251a is the N pole, and the bottom of the first magnetic part 251a is the S pole. The magnetic pole of the first magnetic part 251a is directed downward, the top of the second magnetic part 251b is the S pole, the bottom of the second magnetic part 251b is the N pole, and the magnetic pole of the second magnetic part 251b is directed upward. In this way, the first magnet 251 has an N pole and an S pole on the side facing the first anti-shake coil 271. It should be noted that, in this application, the magnetic pole direction (NS) refers to the direction extending from the N pole to the S pole.

[0137] Of course, in the present application, the second magnet 252 and the third magnet 253 can be implemented as two-pole magnets, with the side of the second magnet 252 closer to the optical axis being the north pole and the side farther from the optical axis being the south pole; and the side of the third magnet 253 closer to the optical axis being the north pole and the side farther from the optical axis being the south pole. It is understood that in the present application, the second magnet 252 and the third magnet 253 can also be multi-pole magnets, such as quadrupole magnets, and this application does not limit this.

[0138] Furthermore, in one embodiment of the present application, the length of the first anti-shake coil 271 is greater than the length of the second anti-shake coil 272 and the third anti-shake coil 273, so as to increase the magnetic thrust generated when the first magnet 251 interacts with the first anti-shake coil 271.

[0139] In the present application, the second magnet 252 and the third magnet 253 of the magnet unit 25 are reused. The second magnet 252 and the third magnet 253 are used to interact with the focus coil unit 26 during the focus function, and are also used to interact with the anti-shake coil unit 27 during the anti-shake function. In other words, the second magnet 252 and the third magnet 253 can simultaneously provide the magnetic fields required by the focus coil unit 26 and the anti-shake coil unit 27.

[0140] Since the first magnet 251 is not used to drive the focusing coil part 26 and the focusing carrier 22 to move, the height dimension of the first magnet 251 is smaller than that of the second magnet 252 and the third magnet 253, and the height of the top surface of the first magnet 251 is also lower than that of the top surfaces of the second magnet 252 and the third magnet 253.

[0141] As mentioned 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. It is understood that 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.

[0142] In another embodiment of the present application, the magnet portion 25 may also include only two magnets, a first magnet 251 and a second magnet 252. In this case, the anti-shake coil portion 27 includes a first anti-shake coil 271 opposite to the first magnet 251 and a second anti-shake coil 272 opposite to the second magnet 252. Reducing one magnet (the third magnet 253) can further reduce the size of the driving device 20, but it also reduces the driving force of the driving device 20, so that when the focusing function is implemented, only one side is provided with the focus coil 261 and the second magnet 252 for driving. Due to the interaction between the 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 imaging of the camera module 1.

[0143] 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.

[0144] In one embodiment of the present application, the driving device 20 includes a first side 201, a second side 202, a third side 203 and a fourth side 204 arranged in sequence around its circumference, wherein the first magnet 251 is arranged on the first side 201 of the driving device 20, the second magnet 252 is arranged on the second side 202 of the driving device 20 adjacent to the first side 201, the third magnet 253 is arranged on the fourth side 204 of the driving device 20 opposite to the second side 202, and the third side 203 is not provided with a magnet.

[0145] As shown in Figures 5 and 6, the focusing coil 261 is circumferentially arranged on the first side 201, the second side 202, the third side 203 and the fourth side 204 of the driving device 20, wherein the focusing coil 261 includes a first focusing coil portion 2611 located on the first side 201, a second focusing coil portion 2612 located on the second side 202, a third focusing coil portion 2613 located on the third side 203 and a fourth focusing coil portion 2614 located on the fourth side 204. It can be seen that the first focusing coil portion 2611 arranged on the same side is in the magnetic field range of the first magnet 251, the second focusing coil portion 2612 is in the magnetic field range of the second magnet 252, and the fourth focusing coil portion 2614 is in the magnetic field range of the third magnet 253. That is to say, after the focusing coil 261 is energized, the magnetic field generated by the first focusing coil portion 2611 interacts with the magnetic field of the first magnet 251, the magnetic field generated by the second focusing coil portion 2612 interacts with the magnetic field of the second magnet 252, and the magnetic field generated by the fourth focusing coil portion 2614 interacts with the magnetic field of the third magnet 253.

[0146] However, since in this application, the magnet portion 25 is only arranged on three sides of the driving device 20, no magnet is arranged on the opposite side of the first magnet 251, that is, no magnet is arranged on the third side 203 opposite to the first side 201. This means that after the focusing coil 261 is energized, only the three sides of the focusing carrier 22 are affected by the driving force, and the focusing carrier 22 will tilt under the action of the asymmetric force.

[0147] Furthermore, under the action of the driving force, the focus carrier 22 will produce translational movement along the Z-axis and rotational movement around the Z-axis. That is, the focus carrier 22 will be subjected to translational thrust and rotational thrust. When implementing the focusing function, it is necessary to minimize the rotational movement of the focus carrier 22 around the Z-axis. Because there is no magnet on the opposite side of the first magnet 251, when one side of the focus carrier 22 is subjected to the driving force generated by the interaction between the first magnet 251 and the first focus coil portion 2611, the other side of the focus carrier 22 opposite to the first side is not subjected to the driving force. That is, there are no mutually symmetrical forces on the two opposite sides of the focus carrier 22 to offset the effect of the rotational force, and the rotational movement of the focus carrier 22 around the Z-axis cannot be reduced, which makes the focus carrier 22 prone to dynamic posture differences.

[0148] In the present application, the second magnet 252 and the third magnet 253 of the magnetic unit 25 are reused, while the first magnet 251 of the magnetic unit 25 is not reused. That is, the first magnet 251 is only used to interact with the first anti-shake coil 271 during the anti-shake function. Therefore, by reducing the interaction between the first magnet 251 and the first focus coil unit 2611 of the focus coil 261, the effect of the driving force generated by the first magnet 251 and the first focus coil unit 2611 on the focus carrier 22 can be reduced, thereby preventing the focus carrier 22 from experiencing dynamic posture differences such as tilt or rotation under the action of asymmetric forces.

[0149] As shown in FIG6 , in one embodiment of the present application, the first focus coil portion 2611 of the focus coil 261 includes a straight side segment 2611a parallel to the length direction of the first magnet 251, and oblique side segments 2611b and 2611c connected to the straight side segment 2611a and forming a certain angle with the length direction of the first magnet 251. There are two oblique side segments 2611b and 2611c, and the two oblique side segments 2611b and 2611c extend from opposite ends of the straight side segment 2611a toward the optical axis. In other words, the first focus coil portion 2611 includes a straight side segment 2611a and two oblique side segments 2611b and 2611c connected to the straight side segment 2611a. In a specific example of the present application, the oblique side segments 2611b and 2611c can be straight segments, or they can be curved segments, which is not limited in the present application.

[0150] It can be understood that, on the one hand, when the magnetic field lines of the magnet are perpendicular to the plane of the coil, the magnetic flux passing through the coil is maximum, and the effective reaction between the magnet and the coil is strongest. Therefore, the straight-side segment 2611a of the first focusing coil portion 2611 and the magnetic field lines of the first magnet 251 are perpendicular to each other. When the straight-side segment 2611a of the first focusing coil portion 2611 is longer, more magnetic field lines pass through the focusing coil 261, the greater the magnetic flux passing through the focusing coil 261, the stronger the effective reaction between the focusing coil 261 and the first magnet 251, the stronger the interaction between the focusing coil 261 and the first magnet 251, and the greater the impact on the focusing carrier 22.

[0151] On the other hand, when viewing the plane along the optical axis, that is, when viewing from above, the straight side segment 2611a of the first focusing coil portion 2611 is closer to the first magnet 251, and the oblique side segments 2611b and 2611c of the first focusing coil portion 2611 are farther from the first magnet 251, that is, the distance from the straight side segment 2611a to the first magnet 251 is smaller than the distance from the two oblique side segments 2611b and 2611c to the first magnet 251, and the effective reaction between the straight side segment 2611a of the first focusing coil portion 2611 and the first magnet 251 is greater. When the length of the straight side segment 2611a of the first focusing coil part 2611 is longer, the length of the two oblique side segments 2611b and 2611c connected to it is shorter, the interaction between the straight side segment 2611a of the first focusing coil part 2611 and the first magnet 251 is stronger, the interaction between the focusing coil 261 and the first magnet 251 is stronger, and the impact on the focusing carrier 22 is greater.

[0152] In summary, the present application reduces the effective interaction between the first magnet 251 and the focusing coil 261 by shortening the length of the straight-side segment 2611a of the first focusing coil portion 2611. In a specific example of the present application, the length of the straight-side segment 2611a of the first focusing coil portion 2611 is shorter than the length of the oblique-side segments 2611b and 2611c, with the straight-side segment 2611a being shortened to its minimum length. In a specific example of the present application, the length of the straight-side segment 2611a ranges from 0.1 mm to 1 mm; further, the length of the straight-side segment 2611a ranges from 0.2 mm to 0.4 mm. This reduces the magnetic field lines through which the focusing coil 261 passes, thereby reducing the effective interaction between the focusing coil 261 and the first magnet 251. Furthermore, the further the first coil portion is from the first magnet 251, the weaker the interaction between the focusing coil 261 and the first magnet 251, thereby reducing the impact of asymmetric forces on the focusing carrier 22. Furthermore, this design can also effectively reduce the resistance value of the non-needed area. It is understandable that the size of the straight edge segment 2611a cannot be infinitely small to avoid making the manufacturing and molding of the focus coil 261 more difficult.

[0153] In another specific example of the present application, the first focusing coil portion 2611 of the focusing coil 261 is an arc-shaped structure or an approximately arc-shaped structure. At this time, the first focusing coil portion 2611 does not have a straight edge segment 2611a, which can better achieve the effect of reducing the effective reaction between the first magnet 251 and the focusing coil 261.

[0154] Continuing with reference to FIG6 , in one embodiment of the present application, the focus coil 261 has a symmetrical structure, namely, the second focus coil portion 2612 is symmetrically arranged with the fourth focus coil portion 2614, and the first focus coil portion 2611 is symmetrically arranged with the third focus coil portion 2613. In a specific example of the present application, the second focus coil portion 2612 of the focus coil 261 has only straight-side segments and no oblique-side segments, namely, the second focus coil portion 2612 extends along the length of the second magnet 252 and is arranged parallel to the length of the second magnet 252; the fourth focus coil portion 2614 of the focus coil 261 has only straight-side segments and no oblique-side segments, namely, the fourth focus coil portion 2614 extends along the length of the third magnet 253 and is arranged parallel to the length of the third magnet 253.

[0155] The sum of the magnetic thrust F2 generated by the interaction between the second focus coil unit 2612 and the second magnet 252, and the magnetic thrust F3 generated by the interaction between the fourth focus coil unit 2614 and the third magnet 253, is more than 20 times the magnetic thrust F1 generated by the interaction between the first focus coil unit 2611 and the first magnet 251. In other words, the greater the ratio of the sum of F2 and F3 to F1, the weaker the interaction between the first focus coil unit 2611 and the first magnet 251, and the smaller the asymmetric force on the focus carrier 22, thereby preventing the focus carrier 22 from causing tilting or rotation.

[0156] It is understood that the lengths of the first magnet 251, the second magnet 252, the third magnet 253, and the second and fourth focus coil sections 2612, 2614 are determined by the size of the drive device 20. In the present application, the magnitude of the magnetic thrust F1 generated by the interaction between the first focus coil section 2611 and the first magnet 251 is adjusted by adjusting the length of the straight-side segment 2611a of the first focus coil section 2611.

[0157] In one embodiment of the present application, the carrier body 221 includes a first side wall 2210, a second side wall 2211, a third side wall 2212 and a fourth side wall 2213 arranged in sequence around its circumference, wherein the first side wall 2210 and the third side wall 2212 are opposite to each other, and the second side wall 2211 and the fourth side wall 2213 are opposite to each other. The focusing coil 261 is arranged around the first side wall 2210, the second side wall 2211, the third side wall 2212 and the fourth side wall 2213 of the carrier body 221. The first focusing coil portion 2611 of the focusing coil 261 is located on the first side wall 2210, the second focusing coil portion 2612 of the focusing coil 261 is located on the second side wall 2211, the third focusing coil portion 2613 of the focusing coil 261 is located on the third side wall 2212, and the fourth focusing coil portion 2614 of the focusing coil 261 is located on the fourth side wall 2213. The first focusing coil portion 2611, the second focusing coil portion 2612, the third focusing coil portion 2613 and the fourth focusing coil portion 2614 of the focusing coil 261 are adapted to the shapes of the first side wall 2210, the second side wall 2211, the third side wall 2212 and the fourth side wall 2213 of the focusing carrier 22.

[0158] In a specific example of the present application, the first side wall 2210 and the third side wall 2212 are concave structures, the first side wall 2210 and the third side wall 2212 have openings facing the optical axis, and the first side wall 2210 and the third side wall 2212 are symmetrically arranged relative to the through hole of the focusing carrier 22; the second side wall 2211 and the fourth side wall 2213 are planar structures, and the second side wall 2211 and the fourth side wall 2213 are symmetrically arranged relative to the through hole of the focusing carrier 22.

[0159] Furthermore, as shown in FIG2 , in one embodiment of the present application, the drive device 20 further includes a magnetic conductive member 28 disposed between the magnet portion 25 and the anti-shake frame 23 to enhance the magnetic field strength of the magnet portion 25. The magnetic conductive member 28 includes a first magnetic conductive member 281, a second magnetic conductive member 282, and a third magnetic conductive member 283. The first magnetic conductive member 281 acts on the first magnet 251, the second magnetic conductive member 282 acts on the second magnet 252, and the third magnetic conductive member 283 acts on the third magnet 253. In one specific example of the present application, the magnetic conductive member 28 is fixed to the magnet mounting slot 232 of the anti-shake frame 23 by bonding or other means. In another specific example of the present application, the magnetic conductive member 28 is embedded in the frame body 231 of the anti-shake frame 23 by, for example, insert molding.

[0160] The first magnetic conductive member 281 is arranged on the side of the first magnet 251 away from the first anti-shake coil 271, that is, the first magnetic conductive member 281 is arranged above the first magnet 251. This arrangement can, on the one hand, concentrate the magnetic lines of force of the first magnet 251 downward to increase the magnetic field strength of the first magnet 251; on the other hand, it can also prevent the magnetic force of the first magnet 251 from overflowing, thereby preventing the interaction between the first magnet 251 and the focusing coil 261, and preventing the focusing carrier 22 from being subjected to asymmetric forces. In a specific example of the present application, the first magnetic conductive member 281 is a U-shaped structure with an opening facing the first anti-shake coil 271. The first magnetic conductive member 281 can cover the top and side surfaces of the first magnet 251 to prevent the magnetic force of the first magnet 251 from overflowing. In another specific example of the present application, the first magnetic conductive member 281 is a planar structure that only covers the top surface of the first magnet 251.

[0161] The second magnetic conductive member 282 is disposed on the side of the second magnet 252 away from the focus coil 261, that is, on the side of the second magnet 252 away from the second focus coil portion 2612, thereby increasing the magnetic field strength on the side of the second magnet 252 facing the focus coil 261. The third magnetic conductive member 283 is disposed on the side of the third magnet 253 away from the focus coil 261, that is, on the side of the third magnet 253 away from the fourth focus coil portion 2614, thereby increasing the magnetic field strength on the side of the third magnet 253 facing the focus coil 261. Furthermore, the second magnet 252 can also be fixed to the second magnetic conductive part 282 through the magnetic attraction between the second magnetic conductive part 282, or the second magnet 252 can be more firmly adsorbed on the frame body 231 through the magnetic attraction between the second magnetic conductive part 282; the third magnet 253 can also be fixed to the third magnetic conductive part 283 through the magnetic attraction between the third magnetic conductive part 283 or be more firmly adsorbed on the frame body 231.

[0162] It is understandable that, in the present application, the magnetic conductive member 28 may not contain magnetism, for example, the magnetic conductive member 28 may be made of ferrite, or the magnetic conductive member 28 itself may be a permanent magnet, and the present application does not impose any limitation on this.

[0163] As shown in Figures 2, 4, and 7 to 11, in one embodiment of the present application, a suspension portion 24 is provided on the focus carrier 22, the anti-shake frame 23, and the base 212, such that the focus carrier 22 is suspended in the anti-shake frame 23, and the anti-shake frame 23 is suspended in the base 212. The suspension portion 24 includes a first suspension portion 241 and a side suspension portion 242. The first suspension portion 241 is connected between the focus carrier 22 and the anti-shake frame 23 to restrict movement of the focus carrier 22 along the optical axis. The focus carrier 22 is suspended within the anti-shake frame 23 via the first suspension portion 241. The side suspension portion 242 is connected between the anti-shake frame 23 and the base 212 to restrict movement of the anti-shake frame 23 in directions perpendicular to the optical axis (X-axis and Y-axis directions). The anti-shake frame 23 is suspended within the base 212 via the side suspension portion 242.

[0164] Specifically, in one embodiment of the present application, the first suspension portion 241 includes a first spring piece 2414 and a second spring piece 2415 which are arranged at intervals on the driving device 20 along the optical axis direction. The first spring piece 2414 is arranged on the object side of the focusing carrier 22, and the second spring piece 2415 is arranged on the image side of the focusing carrier 22, so as to suspend the focusing carrier 22 in a resettable manner in the anti-shake frame 23. The focusing carrier 22 is suspended in the anti-shake frame 23 under the action of the first spring piece 2414 and the second spring piece 2415.

[0165] Among them, the first spring piece 2414 and the second spring piece 2415 are generally thin-sheet structures. The first spring piece 2414 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 2415 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.

[0166] More specifically, in one embodiment of the present application, the first suspension portion 241 includes an outer profile 2411 fixed to the anti-shake frame 23, an inner profile 2412 fixed to the focus carrier 22, and a deformable portion 2413 integrally connecting the outer profile 2411 and the inner profile 2412. The deformable portion 2413 extends in a curved manner from the outer profile 2411 to the inner profile 2412 to reserve sufficient space for the movement of the focus carrier 22. This not only ensures the movement range of the focus carrier 22, but also reduces the driving resistance of the focus carrier 22, thereby improving the optical focus sensitivity of the driving device 20.

[0167] It is understood that the longer the deformable portion 2413 is and the more bends it has, the smaller the deformation of the deformable portion 2413 itself will be after deformation, making it easier for the deformable portion 2413 to return to its original position after being stretched. In one specific example of the present application, the deformable portion 2413 is an elastic linear structure made of an elastic material (such as rubber, plastic, etc.); in another specific example of the present application, the deformable portion 2413 can also be an elastic linear structure made of a rigid material (such as metal, etc.).

[0168] The outer profile 2411 of the first spring piece 2414 is fixed to the top surface of the anti-shake frame 23, the inner profile 2412 of the first spring piece 2414 is fixed to the top surface of the focus carrier 22, and the deformed portion 2413 of the first spring piece 2414 integrally connects the outer profile 2411 and the inner profile 2412 of the first spring piece 2414. The outer profile 2411 of the second spring piece 2415 is fixed to the bottom surface of the anti-shake frame 23, the inner profile 2412 of the second spring piece 2415 is fixed to the bottom surface of the focus carrier 22, and the deformed portion 2413 of the second spring piece 2415 integrally connects the outer profile 2411 and the inner profile 2412 of the second spring piece 2415. This arrangement allows the focus carrier 22 to be clamped between the first spring piece 2414 and the second spring piece 2415, so that the focus carrier 22 is suspended within the anti-shake frame 23.

[0169] The inner profile 2412 and outer profile 2411 of the first elastic piece 2414 can be fixedly attached to the focus carrier 22 and the anti-shake frame 23 by means such as, but not limited to, bonding or hot riveting. The inner profile 2412 and outer profile 2411 of the second elastic piece 2415 can be fixedly attached to the focus carrier 22 and the anti-shake frame 23 by means such as, but not limited to, bonding or hot riveting. When the focus carrier 22 is driven to move along the Z-axis, the first elastic piece 2414 and the second elastic piece 2415 deform to accumulate elastic force. When the focus carrier 22 stops being driven, the accumulated elastic force of the first elastic piece 2414 and the second elastic piece 2415 is released, thereby driving the focus carrier 22 to return to its original position.

[0170] Furthermore, in one embodiment of the present application, the first spring clip 2414 can have an integrated structure, and the second spring clip 2415 can have a split structure, and the second spring clip 2415 can be used to achieve circuit conduction of the drive device 20; the first spring clip 2414 can always maintain good consistency during installation, so that the entire plane of the first spring clip 2414 produces less installation tolerance. In another embodiment of the present application, the first spring clip 2414 has a split structure, and the second spring clip 2415 has a split structure, and both the first spring clip 2414 and the second spring clip 2415 can be used to achieve circuit conduction of the drive device 20.

[0171] The first spring piece 2414 has a symmetrical structure. When the focus carrier 22 moves along the Z-axis, the symmetrical first spring piece 2414 can suppress the focus carrier 22 from rotating about the Z-axis. In one specific example of the present application, the first spring piece 2414 has a split structure, which includes four first spring pieces arranged at 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 a symmetrical restoring force for the focus carrier 22. In another specific example of the present application, the first spring piece 2414 has a split structure, which includes two first spring pieces symmetrically arranged between the focus carrier 22 and the anti-shake frame 23; or, in yet another specific example of the present application, the first spring piece 2414 has a one-piece structure, which has a common inner profile 2412, four outer profiles 2411, and four deformable portions 2413.

[0172] The second spring piece 2415 has a symmetrical structure. When the focus carrier 22 moves along the Z-axis, the symmetrical second spring piece 2415 can suppress the focus carrier 22 from rotating about the Z-axis. In a specific example of the present application, the second spring piece 2415 has a split structure, which includes two parts arranged symmetrically about the axis, namely, a first lower spring piece 24151 and a second lower spring piece 24152. The axisymmetric second spring piece 2415 can further improve the flatness of the second spring piece 2415, thereby reducing the tilt tolerance of the drive device 20 and improving the assembly accuracy of the drive device 20. In a specific example of the present application, the first lower spring piece 24151 and the second lower spring piece 24152 extend along the length direction of the second magnet 252 and the third magnet 253, and the first lower spring piece 24151 and the second lower spring piece 24152 are symmetrically distributed relative to the center line of the first magnet 251. That is, the first lower elastic piece 24151 and the second lower elastic piece 24152 are symmetrically arranged on the bottom surface of the focusing carrier 22 .

[0173] In one embodiment of the present application, each portion of the second elastic piece 2415, namely the first lower elastic piece 24151 and the second lower elastic piece 24152, respectively, has two outer profiles 2411, two deformable portions 2413, and an inner profile 2412. One end of the inner profile 2412 is connected to one deformable portion 2413, the other end of which is connected to one outer profile 2411; the other end of the inner profile 2412 is connected to another deformable portion 2413, the other end of which is connected to another outer profile 2411. In other words, the structure of the first lower elastic piece 24151 and the second lower elastic piece 24152 is: outer profile 2411, deformable portion 2413, inner profile 2412, deformable portion 2413, and outer profile 2411.

[0174] Specifically, the first lower elastic piece 24151 of the second elastic piece 2415 includes a first outer profile 2411a, a second outer profile 2411b, a first inner profile 2412a, a first deformation portion 2413a connecting the first inner profile 2412a and the first outer profile 2411a, and a second deformation portion 2413b connecting the first inner profile 2412a and the second outer profile 2411b.

[0175] The first inner profile 2412a is fixed to the focus carrier 22, and the first outer profile 2411a and the second outer profile 2411b are fixed to the anti-shake frame 23. In a specific example of the present application, the first outer profile 2411a and the second outer profile 2411b are fixed to two opposite sides of the anti-shake frame 23, for example, the first side 201 and the third side 203 opposite thereto.

[0176] The second lower elastic piece 24152 of the second elastic piece 2415 includes a third outer profile 2411c, a fourth outer profile 2411d, a second inner profile 2412b, a third deformable portion 2413c connecting the second inner profile 2412b and the third outer profile 2411c, and a fourth deformable portion 2413d connecting the second inner profile 2412b and the fourth outer profile 2411d. The second inner profile 2412b is fixed to the focus carrier 22, while the third outer profile 2411c and the fourth outer profile 2411d are fixed to the anti-shake frame 23. In a specific example of the present application, the third outer profile 2411c and the fourth outer profile 2411d are fixed to opposite sides of the anti-shake frame 23, for example, the first side 201 and the opposing third side 203.

[0177] The first lower spring piece 24151 and the second lower spring piece 24152 of the second spring piece 2415 are positioned opposite each other near the second magnet 252 and the third magnet 253. The second magnet 252 and the third magnet 253 are positioned on opposite sides of the focus coil 261. When the focus coil 261 is energized, the second magnet 252 and the third magnet 253 interact with the focus coil 261, generating symmetrical forces that drive the focus coil 261 and the focus carrier 22 along the optical axis. The first lower spring piece 24151 and the second lower spring piece 24152 of the second spring piece 2415 thus generate symmetrical restoring forces, ensuring smooth movement of the focus carrier 22.

[0178] As shown in Figures 10 and 11, in one embodiment of the present application, a side suspension portion 242 is provided on the side walls of the anti-shake frame 23 and the base 212. A first elastic piece 2414 is provided on the top surface of the anti-shake frame 23, and a second elastic piece 2415 is provided on the bottom surface of the anti-shake frame 23. The side suspension portion 242 extends from the bottom surface of the anti-shake frame 23 to the side of the anti-shake frame 23. One end of the side suspension portion 242 is connected to the anti-shake frame 23, and the other end is connected to the base 212. This supports and limits the anti-shake frame 23, not only helping to improve the structural stability of the drive device 20, but also enabling the anti-shake frame 23 to move and reset within a certain range of travel.

[0179] Referring to Figures 7 to 10 , the side suspension portion 242 includes at least two side springs. Each side spring includes a first connection end 2425 connected to the anti-shake frame 23, a second connection end 2426 connected to the base 212, and an elastically deformable portion 2427 integrally connecting the first connection end 2425 and the second connection end 2426. The elastically deformable portion 2427 includes a plurality of interconnected curved segments extending in the X direction and a plurality of interconnected curved segments extending in the Y direction. The plurality of interconnected curved segments extending in the X direction and the plurality of interconnected curved segments extending in the Y direction are interconnected. The elastically deformable portion 2427 deforms when 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 suspension portion 242.

[0180] The side suspension portion 242 includes a planar structure 242a and an upright structure 242b that are perpendicular or approximately perpendicular to each other. The first connecting end 2425 and the second connecting end 2426 extend horizontally to form the planar structure 242a, and the elastic deformation portion 2427 extends vertically to form the upright structure 242b. Specifically, the side suspension portion 242 includes the planar structure 242a that connects the anti-shake frame 23 and the base 212, and the upright structure 242b that bends from the planar structure 242a and extends vertically. In a specific example of the present application, the planar structure 242a extends horizontally and is integrally connected to the second elastic plate 2415, while the upright structure 242b bends from the planar structure 242a and extends vertically. Alternatively, the multiple side elastic plates are formed by bending the horizontal plane where the second elastic plate 2415 is located upward in the vertical direction.

[0181] A bending portion 2428 is defined between the first connection end 2425 and the elastic deformation portion 2427 , and a bending portion 2428 is defined between the second connection end 2426 and the elastic deformation portion 2427 to bend the side suspension portion 242 from extending horizontally to extending in a height direction.

[0182] In one embodiment of the present application, the side suspension portion 242 includes four side springs, two of which are disposed on one side of the anti-shake frame 23, and the other two of which are symmetrically disposed on the other side of the anti-shake frame 23 opposite to the first side. For example, in a specific example of the present application, two of the four side springs are disposed on the first side 201, and the other two of which are symmetrically disposed on the third side 203 opposite to the first side 201.

[0183] Furthermore, in one embodiment of the present application, the elastic deformation portions 2427 of the four side springs are symmetrically arranged on one side of the anti-shake frame 23 where the first magnet 251 is located and the other side opposite to the first side, for example, the first side 201 and the third side 203 .

[0184] The planes on which the elastic deformation portions 2427 of the two side elastic sheets located on the same side overlap with each other; the planes on which the elastic deformation portions 2427 of the two side elastic sheets located on opposite sides overlap with each other. For example, in a specific example of the present application, the elastic deformation portions 2427 of two of the four side elastic sheets are located on the first side 201, and the elastic deformation portions 2427 of the two side elastic sheets located on that side overlap with each other; the elastic deformation portions 2427 of the other two of the four side elastic sheets are located on the third side 203, and the elastic deformation portions 2427 of the two side elastic sheets located on that side overlap with each other; and the plane on which the elastic deformation portion 2427 of one of the side elastic sheets located on the first side 201 and the plane on which the elastic deformation portion 2427 of one of the side elastic sheets located on the third side 203 are parallel to each other.

[0185] The plane of the vertical structure 242b formed by the elastic deformation portion 2427 of each side spring piece is parallel to the length direction of the first magnet 251. When viewed along the height direction, the length direction of the vertical structure 242b formed by the elastic deformation portion 2427 of each side spring piece is the same as the length direction of the first magnet 251.

[0186] As shown in Figures 8A and 8B, Figure 8B is an enlarged schematic diagram of the circular area A in Figure 8A. Looking at its plane along the height direction, that is, from a top-down perspective, the upright structure 242b has a certain width W1 along the length direction of the first magnet 251, and the upright structure 242b has a certain width W2 along the width direction of the first magnet 252 (or along the length direction of the second magnet 252 and the third magnet 253). Among them, the width W1 of the upright structure 242b along the length direction of the first magnet 251 is greater than the width W2 of the upright structure 242b along the length direction of the second magnet 252 or the third magnet 253, that is, W1>W2.

[0187] The length of the first magnet 251 is oriented along the X-axis, while the length of the second magnet 252 or the third magnet 253 is oriented along the Y-axis. This indicates that the width of the elastically deformable portion 2427 of the side suspension 242 differs along the X-axis and Y-axis directions. Consequently, the K value of the elastically deformable portion 2427 of the side suspension 242 differs significantly between the K value in the X-axis and the K value in the Y-axis directions. When viewed from the height, the K value is smaller in directions where the elastically deformable portion 2427 is smaller, and larger in directions where the elastically deformable portion is wider.

[0188] Among them, when looking at the plane along the height direction, that is, from a top-down perspective, the direction in which the elastic deformation part 2427 has a smaller width is the same as the direction in which the anti-shake coil part 27 drives the first magnet 251 to move; the direction in which the elastic deformation part 2427 has a larger width is the same as the direction in which the anti-shake coil part 27 drives the second magnet 252 or the third magnet 253 to move.

[0189] In a specific example of the present application, the width of the elastic deformation part 2427 of the side suspension part 242 along the Y-axis direction is small, and the K value of the elastic deformation part 2427 is small, so it can be deformed under the action of a small driving force. Therefore, the first magnet 251 is arranged along the X-axis direction, and the driving force along the Y-axis direction is generated by the action of the first magnet 251 and the first anti-shake coil 271 to drive the elastic deformation part 2427 to deform; the width of the elastic deformation part 2427 of the side suspension part 242 along the X-axis direction is large, and it can be deformed under the action of a large driving force. Therefore, the second magnet 252 and the third magnet 253 are arranged along the Y-axis direction, and the second magnet 252, the third magnet 253 interact with the second anti-shake coil 272, and the third anti-shake coil 273 to generate a driving force along the X-axis direction to drive the elastic deformation part 2427 to deform.

[0190] Furthermore, when viewed along the height direction, the direction in which the elastically deformable portion 2427 has a smaller width corresponds to the direction in which the first magnet 251 is driven; the direction in which the elastically deformable portion 2427 has a larger width corresponds to the direction in which the second magnet 252 or the third magnet 253 is driven. In a specific example of the present application, the direction in which the elastically deformable portion 2427 has a smaller width corresponds to the Y-axis direction, and the direction in which the first magnet 251 and the first anti-shake coil 271 interact to generate the driving force is the Y-axis direction; the direction in which the elastically deformable portion 2427 has a larger width corresponds to the X-axis direction, and the direction in which the second magnet 252, the third magnet 253, the second anti-shake coil 272, and the third anti-shake coil 273 interact to generate the driving force is the X-axis direction.

[0191] This arrangement can determine the magnets to be arranged in the direction according to the thickness of the elastic deformation portion 2427 along the X-axis and Y-axis directions. On the one hand, the functions of the various parts of the side suspension portion 242 are more fully utilized. On the other hand, when the driving device 20 in this embodiment is applied to the array module, the camera module monomer of another array module can be placed in close proximity to the side of the camera module 1 in this embodiment without interference. The arrangement of this application also helps to reduce costs.

[0192] In the present application, each side spring piece of the side suspension portion 242 can be connected to the first spring piece 2414 or the second spring piece 2415 as a whole. It is understood that each side spring piece of the side suspension portion 242 can be formed by bending again after being integrally formed with the first spring piece 2414 or the second spring piece 2415. Each side spring piece of the side suspension portion 242 can also be manufactured and formed first and then connected to the first spring piece 2414 or the second spring piece 2415 by welding or other methods. This application does not limit this.

[0193] However, when the side suspension portion 242 and the first elastic piece 2414 are integrally connected, the side suspension portion 242 is closer to the object side of the drive device 20, and the bearing surface of the side suspension portion 242 is higher. If the height of the base 212 is relatively low, the elastic deformation portion 2427 of the side suspension portion 242 needs to be extended to a longer length so that the second connection end 2426 of the side suspension portion 242 can be connected to the base 212. However, this situation will cause the elastic deformation portion 2427 of the side suspension portion 242 to extend to a very long length, which will reduce controllability and increase manufacturing difficulty. If the height of the base 212 is increased and extended toward the object side, the reliability of the base 212 will be reduced, which will in turn reduce the reliability of the entire drive device 20. Furthermore, if the circuit conduction of the drive device 20 is achieved through the first elastic piece 2414 and the side suspension portion 242, the conductive structure will become more complex, resulting in increased costs.

[0194] In the present application, a structure is adopted in which the side suspension portion 242 and the second elastic plate 2415 are integrally connected. That is, the side suspension portion 242 and the second elastic plate 2415 are integrally connected. The side suspension portion 242 extends from the image side of the driving device 20 toward the object side. The side suspension portion 242 extends from the bottom surface of the anti-shake frame 23 to the side surface of the anti-shake frame 23. The anti-shake frame 23 is suspended within the base 212 by the side suspension portion 242. Furthermore, the second connection end 2426 of the side suspension portion 242 is fixedly attached to the base boss 2123 of the base 212 by means such as, but not limited to, bonding or hot riveting. The first connection end 2425 of the side suspension portion 242 is indirectly fixed to the anti-shake frame 23 by being connected to the second elastic plate 2415.

[0195] The plane where the second connection end 2426 of the base boss 2123 is connected is lower than the plane where the first connection end 2425 of the anti-shake frame 23 is connected. This arrangement allows the supporting surface of the side suspension portion 242 on the base 212 to be lower, making the base 212 easier to form and more reliable.

[0196] Furthermore, the height of the side suspension portion 242 extending from the side of the anti-shake frame 23 is lower than the top surface of the anti-shake frame 23. In other words, when the side suspension portion 242 and the second elastic piece 2415 are integrally connected, the height extension of the elastic deformation portion 2427 of the side suspension portion 242 can be further shortened, thereby improving the controllability of the side suspension portion 242 and simplifying its manufacturing. Of course, the second elastic piece 2415 is closer to the base 212, allowing a simpler conductive structure to achieve circuit conductivity in the drive device 20.

[0197] It can be understood that the elastic deformation portion 2427 of the side suspension portion 242 in the present application extends toward the object side along the height direction. Since the extension height of the elastic deformation portion 2427 is relatively short, compared with the prior art, the present application cancels the setting of damping rubber at the top of the elastic deformation portion 2427, thereby reducing the space required for setting the damping rubber in the driving device 20, thereby achieving a reduction in the size of the driving device 20.

[0198] The side suspension portion 242 and the second elastic piece 2415 are integrally formed. Bending the side suspension portion 242 significantly increases the K value (elastic modulus) of the side suspension portion 242 and the second elastic piece 2415, thereby supporting the entire anti-shake frame 23 and suspending the anti-shake frame 23 within the base 212. Furthermore, the elastically deformable portion 2427 of the side suspension portion 242 can extend to a smaller height, thereby reducing costs.

[0199] As shown in Figures 7 and 9, in one embodiment of the present application, the side suspension portion 242 includes a first side elastic piece 2421, a second side elastic piece 2422, a third side elastic piece 2423, and a fourth side elastic piece 2424. The first side elastic piece 2421, the second side elastic piece 2422, and the first lower elastic piece 24151 of the second elastic piece 2415 are connected together to form a first lower suspension assembly 2401, and the third side elastic piece 2423, the fourth side elastic piece 2424, and the second lower elastic piece 24152 of the second elastic piece 2415 are connected together to form a second lower suspension assembly 2402. The first lower suspension assembly 2401 and the second lower suspension assembly 2402 are symmetrically arranged. That is, the first side spring clip 2421 and the second side spring clip 2422 are disposed on one side of the drive device 20, and the third side spring clip 2423 and the fourth side spring clip 2424 are disposed on the opposite side of the drive device 20, so that the anti-shake frame 23 is subjected to symmetrical restoring forces after movement. In a specific example of the present application, the first side spring clip 2421 and the second side spring clip 2422 are respectively located on the side proximate to the second magnet 252, and the third side spring clip 2423 and the fourth side spring clip 2424 are respectively located on the side proximate to the third magnet 253. That is, the first lower suspension assembly 2401 extends along the length of the second magnet 252, and the second lower suspension assembly 2402 extends along the length of the third magnet 253, and the first lower suspension assembly 2401 and the second lower suspension assembly 2402 are symmetrical with each other.

[0200] Specifically, the first connecting end 2425 of the first side elastic piece 2421 is indirectly connected to the anti-shake frame 23 by connecting to the first outer profile 2411a of the second elastic piece 2415, and the second connecting end 2426 of the first side elastic piece 2421 is directly connected to the base 212; the first connecting end 2425 of the second side elastic piece 2422 is indirectly connected to the anti-shake frame 23 by connecting to the second outer profile 2411b of the second elastic piece 2415, and the second connecting end 2426 of the second side elastic piece 2422 is connected to the base 212. ; The first connection end 2425 of the third side spring clip 2423 is indirectly connected to the anti-shake frame 23 by connecting to the third outer profile 2411c of the second spring clip 2415, and the second connection end 2426 of the third side spring clip 2423 is directly connected to the base 212; the first connection end 2425 of the fourth side spring clip 2424 is indirectly connected to the anti-shake frame 23 by connecting to the fourth outer profile 2411d of the second spring clip 2415, and the second connection end 2426 of the fourth side spring clip 2424 is directly connected to the base 212.

[0201] Among them, the second connection end 2426 of the first side spring clip 2421, the second connection end 2426 of the second side spring clip 2422, the second connection end 2426 of the third side spring clip 2423 and the second connection end 2426 of the fourth side spring clip 2424 are fixed to the base boss 2123, so that the first side spring clip 2421, the second side spring clip 2422, the third side spring clip 2423 and the fourth side spring clip 2424 are connected to the base 212.

[0202] Referring to FIG9 , in one embodiment of the present application, at least a portion of the second elastic piece 2415 and at least a portion of the side suspension portion 242 form a lower suspension assembly. Alternatively, the drive device 20 includes at least one lower suspension assembly, which includes a lower elastic piece and at least two side elastic pieces integrally connected to the lower elastic piece. The at least one lower suspension assembly is disposed between the base 212 and the anti-shake frame 23 to support and limit the position of the anti-shake frame 23. It will be understood that in the present application, the structures of the lower elastic piece and the two side elastic pieces can all follow the structure of the side suspension portion 242 and the second elastic piece 2415 described above.

[0203] There are at least two lower suspension assemblies, symmetrically arranged on the bottom surface of the anti-shake frame 23. The anti-shake frame 23 is suspended within the base 212 by the lower suspension assemblies. When the driving assembly drives the anti-shake frame 23 to move relative to the base 212, at least two side springs of the lower suspension assemblies deform to accumulate elastic force. When the anti-shake frame 23 is no longer driven, the accumulated elastic force of the at least two side springs of the lower suspension assemblies is released, thereby driving the anti-shake frame 23 to return to its original position.

[0204] In a specific example of the present application, there are two lower suspension assemblies, including a first lower suspension assembly 2401 and a second lower suspension assembly 2402. The lower springs include a first lower spring 24151 and a second lower spring 24152, and at least two side springs include a first side spring 2421, a second side spring 2422, a third side spring 2423, and a fourth side spring 2424. The first side spring 2421, the second side spring 2422, and the first lower spring 24151 are connected to form the first lower suspension assembly 2401; the third side spring 2423, the fourth side spring 2424, and the second lower spring 24152 are connected to form the second lower suspension assembly 2402. The first lower suspension assembly 2401 and the second lower suspension assembly 2402 are symmetrically arranged between the anti-shake frame 23 and the base 212 to provide a more symmetrical restoring force for the anti-shake frame 23.

[0205] It is understood that in the present application, the at least two side springs include a planar structure 242a connecting the base 212 and the lower spring, a vertical structure 242b bent from the planar structure 242a and extending in the height direction, and a bent portion 2428 connecting the planar structure 242a and the vertical structure 242b, wherein the planar structures 242a of the at least two side springs are located on the same side of the bent portion 2428. In other words, when the at least one lower suspension assembly is laid flat on a horizontal surface, the planar structure 242a of each side spring is disposed on the same side of the vertical structure 242b, and the vertical structure 242b of each side spring is bent from the same side of the planar structure 242a in the same direction. This arrangement can improve the consistency and flatness of the at least one lower suspension assembly.

[0206] The lower spring piece is arranged between at least two side spring pieces. The lower spring piece includes an inner profile 2412, two deformation portions 2413 connected to the inner profile 2412, and two outer profiles 2411 connected to the two deformation portions 2413. The planar structures 242a of the two side spring pieces extend in the same direction and are respectively connected to the two outer profiles 2411.

[0207] Specifically, each side spring plate includes a first connecting end 2425 connected to the outer profile 2411 of the lower spring plate 2415, a second connecting end 2426 connected to the base 212, and an elastic deformation portion 2427 integrally connecting the first connecting end 2425 and the second connecting end 2426. The first connecting end 2425 and the second connecting end 2426 extend in the horizontal direction to form a planar structure 242a, and the elastic deformation portion 2427 extends in the height direction to form an upright structure 242b.

[0208] More specifically, a bending portion 2428 is provided between the first connection end 2425 and the elastic deformation portion 2427 , and a bending portion 2428 is provided between the second connection end 2426 and the elastic deformation portion 2427 . The bending portion 2428 bends each side spring sheet from extending in the horizontal direction along the same direction to extending in the height direction.

[0209] Continuing with reference to FIG9 , in one embodiment of the present application, the planar structures 242a of the first side spring piece 2421 and the second side spring piece 2422 are both located on the same side of the bending portion 2428, and the first side spring piece 2421 and the second side spring piece 2422 are bent in the same direction. The planar structures 242a of the third side spring piece 2423 and the fourth side spring piece 2424 are both located on the same side of the bending portion 2428, and the third side spring piece 2423 and the fourth side spring piece are bent in the same direction. In another embodiment of the present application, the planar structures 242a of the first side spring piece 2421, the second side spring piece 2422, the third side spring piece 2423, and the fourth side spring piece 2424 are all located on the same side of the bending portion 2428, and the first side spring piece 2421, the second side spring piece 2422, the third side spring piece 2423, and the fourth side spring piece 2424 are all bent in the same direction.

[0210] The two side springs integrally connected to the lower spring extend in the same direction, and the elastic deformation portions 2427 of the two side springs are located on the same side of the first connecting end 2425 and the second connecting end 2426. In other words, the elastic deformation portions 2427 of the two side springs bend in the same direction. For example, in a specific example of the present application, the planar structure 242a of the first side spring 2421 and the second side spring 2422 forming the first lower suspension assembly 2401 are disposed on the same side of the upright structure 242b, i.e., the first side spring 2421 and the second side spring 2422 bend in the same direction; and the planar structure 242a of the third side spring 2423 and the fourth side spring 2424 forming the second lower suspension assembly 2402 are disposed on the same side of the upright structure 242b, i.e., the third side spring 2423 and the fourth side spring 2424 bend in the same direction.

[0211] It can be understood that in the present application, the planar structure 242a of the first side spring clip 2421, the second side spring clip 2422, the third side spring clip 2423, and the fourth side spring clip 2424 can also be set on the same side of the vertical structure 242b, that is, the first side spring clip 2421, the second side spring clip 2422, the third side spring clip 2423 and the fourth side spring clip 2424 are all bent in the same direction.

[0212] In the present application, the structural design of bending in the same direction can effectively improve the design difficulty of the bending jig, making it easier to demold the side suspension portion 242 or at least two side springs or the lower suspension component, thereby improving yield and reducing costs. This is because in order to ensure that the elastic deformation portion 2427 can be bent within 90°±3°, the jig design must be bent beyond 100°, and the elastic deformation portion 2427 can only be controlled near 90° after rebounding. If the bending direction of the elastic deformation portion 2427 is inconsistent, it will cause the jig to be unable to be demolded due to the different bending directions, resulting in reduced yield and increased costs.

[0213] In a specific example of the present application, the first side spring piece 2421 and the second side spring piece 2422 extend along the Y-axis direction, the upright structure 242b of the first side spring piece 2421 is located on the left side of the planar structure 242a, and the bent portion 2428 of the first side spring piece 2421 is located on the left side of the planar structure 242a; the upright structure 242b of the second side spring piece 2422 is located on the left side of the planar structure 242a, and the bent portion 2428 of the second side spring piece 2422 is located on the left side of the planar structure 242a, and the upright structure 242b of the first side spring piece 2421 and the upright structure 242b of the second side spring piece 2422 are respectively bent from the left side of the planar structure 242a along the horizontal direction toward the height direction. That is, the elastic deformation portion 2427 of the first side spring piece 2421 is located to the left of the first connection end 2425 and the second connection end 2426 of the first side spring piece 2421, and the elastic deformation portion 2427 of the second side spring piece 2422 is located to the left of the first connection end 2425 and the second connection end 2426 of the second side spring piece 2422. The elastic deformation portion 2427 of the first side spring piece 2421 and the elastic deformation portion 2427 of the second side spring piece 2422 are both bent from the left side along the horizontal direction toward the height direction. Of course, the elastic deformation portion 2427 of the first side spring piece 2421 and the elastic deformation portion 2427 of the second side spring piece 2422 can also be bent from the right side along the horizontal direction toward the height direction, and this application does not limit this.

[0214] Similarly, the third side spring piece 2423 and the fourth side spring piece 2424 extend along the Y-axis direction, the upright structure 242b of the third side spring piece 2423 is located on the left side of the planar structure 242a, and the bent portion 2428 of the third side spring piece 2423 is located on the left side of the planar structure 242a; the upright structure 242b of the fourth side spring piece 2424 is located on the left side of the planar structure 242a, and the bent portion 2428 of the fourth side spring piece 2424 is located on the left side of the planar structure 242a. The upright structure 242b of the third side spring piece 2423 and the upright structure 242b of the fourth side spring piece 2424 are bent from the left side of the planar structure 242a along the horizontal direction toward the height direction. That is to say, the elastic deformation portion 2427 of the third side spring piece 2423 is located on the left side of the first connection end 2425 and the second connection end 2426 of the third side spring piece 2423, and the elastic deformation portion 2427 of the fourth side spring piece 2424 is located on the left side of the first connection end 2425 and the second connection end 2426 of the fourth side spring piece 2424. The elastic deformation portion 2427 of the third side spring piece 2423 and the elastic deformation portion 2427 of the fourth side spring piece 2424 are both bent from the left side along the horizontal direction toward the height direction. Of course, the elastic deformation part 2427 of the third side spring piece 2423 and the elastic deformation part 2427 of the fourth side spring piece 2424 can also be bent from the right side along the horizontal direction toward the height direction. This application does not impose any restrictions on this. As shown in Figures 7, 8A and 10, the plane where the elastic deformation part 2427 of the first side spring piece 2421 is located is parallel to the plane where the elastic deformation part 2427 of the second side spring piece 2422 is located, and the plane where the elastic deformation part 2427 of the third side spring piece 2423 is located is parallel to the plane where the elastic deformation part 2427 of the fourth side spring piece 2424 is located. The elastic deformation parts 2427 of the four side spring pieces are arranged on the side where the first magnet 251 is located and the other side opposite to this side.

[0215] The elastic deformation portion 2427 of the first side spring piece 2421 is located on the side where the first magnet 251 is located, for example, the first side 201, and the plane where the elastic deformation portion 2427 of the first side spring piece 2421 is located is parallel to the length direction of the first magnet 251; the elastic deformation portion 2427 of the second side spring piece 2422 is located on the other side opposite to the side where the first magnet 251 is located, for example, the third side 203 opposite to the first side 201, and the plane where the elastic deformation portion 2427 of the second side spring piece 2422 is located is parallel to the plane where the elastic deformation portion 2427 of the first side spring piece 2421 is located; the first lower spring piece 24152 is located on the bottom surface of the anti-shake frame 23 and close to the fourth side 204.

[0216] Furthermore, the elastic deformation portion 2427 of the third side spring piece 2423 is located on the side where the first magnet 251 is located, for example, the first side 201, and the plane where the elastic deformation portion 2427 of the third side spring piece 2423 is located is parallel to the length direction of the first magnet 251; the elastic deformation portion 2427 of the fourth side spring piece 2424 is located on the side opposite to the side where the first magnet 251 is located, for example, the third side 203 opposite to the first side 201, and the plane where the elastic deformation portion 2427 of the fourth side spring piece 2424 is located is parallel to the plane where the elastic deformation portion 2427 of the third side spring piece 2423 is located; the second lower spring piece 24151 is located on the bottom surface of the anti-shake frame 23 and close to the second side 202.

[0217] That is to say, the first side spring clip 2421 and the third side spring clip 2423 are arranged on the same side of the first magnet 251, and the second side spring clip 2422 and the fourth side spring clip 2424 are arranged on the opposite side of the first magnet 251. The plane where the elastic deformation part 2427 of the first side spring clip 2421 is located, the plane where the elastic deformation part 2427 of the second side spring clip 2422 is located, the plane where the elastic deformation part 2427 of the third side spring clip 2423 is located, and the plane where the elastic deformation part 2427 of the fourth side spring clip 2424 is located are parallel to the length direction of the first magnet 251, so as to provide a more symmetrical reset force for the anti-shake frame 23.

[0218] It is worth mentioning that in the present application, the circuit conduction of the drive device 20 can be achieved by the second side spring piece 2422 and the fourth side spring piece 2424 disposed on the opposite side of the first magnet 251, which can improve the space utilization of the drive device 20. Of course, the circuit conduction of the drive device 20 can also be achieved by the first side spring piece 2421, the second side spring piece 2422, the third side spring piece 2423, and the fourth side spring piece 2424, and this application does not limit this.

[0219] As shown in FIG4 , the frame body 231 further includes a first notch 2311, a second notch 2312, a third notch 2313, and a fourth notch 2314 at its four corners. The first notch 2311, the second notch 2312, the third notch 2313, and the fourth notch 2314 can be recessed inward from the first side 201 and the third side 203, or can be recessed inward from the second side 202 and the fourth side 204. The first notch 2311, the second notch 2312, the third notch 2313, and the fourth notch 2314 can provide accommodation space for the first side spring clip 2421, the second side spring clip 2422, the third side spring clip 2423, and the fourth side spring clip 2424. That is, the recessed direction of the notch is the same as the extending direction of the first side spring clip 2421, the second side spring clip 2422, the third side spring clip 2423, and the fourth side spring clip 2424.

[0220] Furthermore, the elastically deformable portions 2427 of the first side spring piece 2421, the second side spring piece 2422, the third side spring piece 2423, and the fourth side spring piece 2424 are disposed within the first, second, third, and fourth constrictions 2311, 2312, 2313, and 2314 of the frame body 231 to prevent the elastically deformable portions 2427 of the four side spring pieces from contacting the anti-shake frame 23 during deformation and causing damage. In other words, each side spring piece has only two fixed ends, and the endpoints of the elastically deformable portions 2427 of each side spring piece are suspended and do not contact other structures.

[0221] In summary, the object side of the focus carrier 22 is provided with a first elastic plate 2414 extending in the horizontal direction, and the image side of the focus carrier 22 is provided with a second elastic plate 2415 extending in the horizontal direction and a plurality of side elastic plates extending in the height direction and integrally connected to the second elastic plate 2415. The plurality of side elastic plates are formed by bending the horizontal plane on which the second elastic plate 2415 is located upward in the height direction. The plane on which the plurality of side elastic plates are located is arranged parallel to the focusing axis of the optical lens 10 installed in the drive device 20, that is, parallel to the optical axis. Therefore, the elastic deformation direction of the plurality of side elastic plates is consistent with the radial direction of the optical lens 10, thereby realizing the anti-shake function. Similarly, the first elastic plate 2414 and the second elastic plate 2415 are arranged along the radial direction of the optical lens 10, and their elastic deformation direction is consistent with the optical axis direction of the optical lens 10, thereby realizing the focusing function.

[0222] As shown in Figures 1, 2, 4 and 11, in one embodiment of the present application, the driving device 20 further includes an anti-shake circuit board 29, the anti-shake circuit board 29 is arranged on the base 212, and the anti-shake coil part 27 is arranged on and electrically connected to the anti-shake circuit board 29, for realizing circuit conduction between the anti-shake coil part 27 and the anti-shake circuit board 29.

[0223] Furthermore, in one embodiment of the present application, the side suspension portion 242 further includes an electrical connection portion 2429, which is integrally bent downward from the second connection end 2426 and extends to the anti-shake circuit board 29, so as to realize circuit conduction between the focusing coil 261 and the anti-shake circuit board 29 through the second spring piece 2415 and the side suspension portion 242.

[0224] The focus coil 261 is mounted on the focus carrier 22. The sidewalls of the focus carrier 22 have at least two winding posts 222. One end of the focus coil 261 is wound around the focus carrier 22, while the other end is wound around the winding posts 222. The focus coil 261, mounted on the winding posts 222, can contact a second spring 2415. The second spring 2415 is integrally connected to the first connection end 2425 of the side suspension 242. The side suspension 242 conducts current from the anti-shake circuit board 29 to the focus coil 261 via the integrally connected second connection end 2426 and electrical connection 2429.

[0225] At least two side springs in the side suspension portion 242 are provided with electrical connection portions 2429. The side springs provided with the electrical connection portions 2429 can be disposed on the side opposite the first magnet 251 to avoid interference with the arrangement of the first magnet 251, thereby improving the space utilization of the drive device 20. In a specific example of the present application, the second side spring 2422 and the fourth side spring 2424, which are disposed on the opposite side of the first magnet 251, are provided with electrical connection portions 2429. Specifically, the electrical connection portion 2429 of the second side spring 2422 is integrally bent downward and extended from the second connection end 2426 of the second side spring 2422, and is electrically connected to the anti-shake circuit board 29; the electrical connection portion 2429 of the fourth side spring 2424 is integrally bent downward and extended from the second connection end 2426 of the fourth side spring 2424, and is electrically connected to the anti-shake circuit board 29.

[0226] Since the second spring piece 2415 and the plurality of side spring pieces are closer to the anti-shake circuit board 29 , the complexity of the circuit of the driving device 20 can be reduced, thereby reducing the cost.

[0227] It is understood that the anti-shake circuit board 29 can extend downward and be electrically connected to the chip circuit board 32 of the photosensitive component 30 to achieve circuit conduction of the driving device 20. Of course, the anti-shake circuit board 29 can also extend directly outward to the motherboard of an electronic device (such as a mobile phone) and be directly electrically connected to the electronic device motherboard to achieve independent control of the driving device 20 and the photosensitive component 30.

[0228] In one embodiment of the present application, the driving device 20 further includes a position sensing unit (not shown), and the position sensing element can be a Hall element, a driving IC or a TMR. The position sensing unit includes a focus position sensing unit (not shown) and an anti-shake position sensing unit (not shown). Among them, the focus position sensing unit is arranged relative to the second magnet 252 or the third magnet 253. When the focus carrier 22 moves, the relative position of the focus position sensing unit and the second magnet 252 or the third magnet 253 changes. According to the strength of the magnetic field of the second magnet 252 or the third magnet 253 sensed by the focus position sensing unit, the position of the focus carrier 22 can be determined, and then the current of the focus coil 261 is adjusted to move the focus carrier 22 to the required position.

[0229] The anti-shake position sensing unit is arranged relative to the first magnet 251, and the anti-shake position sensing unit is arranged relative to the second magnet 252 or the third magnet 253. When the anti-shake frame 23 moves, the relative position of the anti-shake position sensing unit and the first magnet 251, the second magnet 252 or the third magnet 253 changes. According to the strength of the magnetic field of the first magnet 251, the second magnet 252 or the third magnet 253 sensed by the anti-shake position sensing unit, the position of the anti-shake frame 23 can be determined, and then the current of the anti-shake coil unit 27 can be adjusted to make the anti-shake frame 23 move to the required position.
