The present application also claims priority to the Chinese Patent Application No. 202411182301.0, filed on August 26, 2024, and entitled "Driving device, camera module and electronic equipment", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of electronic equipment, and in particular to a driving device, a camera module and an electronic equipment. BACKGROUND

[0003] With the development of camera technology, the requirement for clear imaging is becoming higher and higher, and various functions for improving imaging clarity are introduced into the camera module, such as using a motor with an optical image stabilization (OIS) function. Among them, the motor with the optical image stabilization function mostly uses the electromagnetic action between the coil and the magnet to control the displacement of the optical device in a certain direction to compensate for the shaking during shooting and increase the clarity of the camera module shooting. However, as the requirement for pixels is becoming higher and higher, the lens volume of the camera module is becoming larger and larger, which increases the lens mass. In addition, in order to meet the shooting quality, the aperture of the camera module also becomes larger and larger, and long-stroke optical stabilization is also needed for the large-mass lens. However, due to the installation space limitation of the motor, the size of the motor itself is limited, and when driving the large-aperture or large-mass lens with better optical performance for long-stroke optical stabilization, the driving force is insufficient. In order to use the lens with higher optical performance in a limited space, especially the lens with larger aperture and larger mass, effective optical image stabilization must be performed; these lenses usually need to be stabilized in a longer stroke range to maintain the stability and clarity of the image. In practical applications, the voice coil motor becomes the mainstream solution for anti-shake. Due to the installation space limitation of the motor, the size of the motor itself is limited, and when driving the large-aperture or large-mass lens with better optical performance for long-stroke optical stabilization, the driving force is insufficient.

[0005] The application provides a driving device, a camera module and an electronic device, and solves the problem of insufficient driving force in the prior art.

[0006] The first aspect of the application provides a driving device, comprising: a first base, a second base, a first driving component and a second driving component; the second base comprises a mounting area, the mounting area comprises a mounting sub-area, the mounting sub-area comprises a hole structure, the hole structure is used for mounting a to-be-driven device, the mounting area has a mounting side, the mounting side comprises a first mounting side and a second mounting side; the first driving component is located on the mounting side, and the first driving component is used for driving the second base to move relative to the first base in a first direction, the first direction being a direction from the first mounting side to the second mounting side; the second driving component is located on the mounting side, and the second driving component is used for driving the second base to move relative to the first base in a second direction, the first direction and the second direction having an included angle; wherein a first projection of the first driving component in a first plane is a first projection, a second projection of the second driving component in the first plane is a second projection, and a third projection of the hole structure in the first plane is a third projection, the first plane being parallel to the first direction, and the first plane being parallel to the second direction.

[0007] A first projection of the first projection in a second plane does not coincide with a third projection of the third projection in the second plane, and a second projection of the second projection in the second plane does not coincide with the third projection of the third projection in the second plane, the second plane being parallel to the first direction, and the second plane being perpendicular to the first plane.

[0013] In some implementations, the axial direction of the hole structure is parallel to the thickness direction of the driving device.

[0014] By adopting the technical scheme, the hole structure is used to facilitate installation of the to-be-driven device, and is conducive to ensuring stability of installation of the to-be-driven device on the driving device, and is also conducive to meeting requirements of the to-be-driven device, such as meeting an optical anti-shake function of an optical device.

[0015] In some implementations, the first direction is parallel to the length direction of the driving device; and a distance between the center of the hole structure and one width side of the driving device is greater than a distance between the center of the hole structure and another width side of the driving device.

[0016] By adopting the technical scheme, when the first driving assembly and the second driving assembly are distributed on the installation side, the installation position of the driving device in the electronic device and the space requirement of the driving device in a single direction in the electronic device can be met.

[0017] In some implementations, the first driving assembly includes a first coil assembly and a first magnetic assembly, and the first coil assembly and the first magnetic assembly are matched; one of the first coil assembly and the first magnetic assembly is fixed on the first base, and the other is fixed on the second base.

The fixed positions of the first coil assembly and the first magnetic group assembly (i.e. on the first base or on the second base) can be designed as required; the fixed positions of the second coil assembly and the second magnetic group assembly (i.e. on the first base or on the second base) can be designed as required, thereby improving the design freedom.

[0022] The second coil assembly includes a second coil and a third magnetic yoke, and the second magnetic group assembly includes a second magnet and a fourth magnetic yoke;

[0023] In the thickness direction of the driving device, the second coil is located between the third magnetic yoke and the second magnetic group assembly, and the second magnet is located between the fourth magnetic yoke and the second coil assembly.

[0024] By adopting the technical scheme, the first magnetic yoke and the first magnetic group assembly are attracted to each other, and the third magnetic yoke and the second magnetic group assembly are attracted to each other, thereby providing an attractive force for the first base and the second base in the thickness direction of the driving device, realizing that the first base and the second base can be combined together in the thickness direction of the driving device and maintaining the distance between the two in the thickness direction of the driving device. After the first coil is powered on, the first coil and the first magnetic group assembly interact with each other to realize linear motion of the second base relative to the first base in the first direction; similarly, after the second coil is powered on, the second coil and the second magnetic group assembly interact with each other to realize linear motion of the second base relative to the first base in the second direction, thereby realizing optical anti-shake of the optical device; after the second base moves relative to the first base in the first direction or the second direction, the first magnetic yoke and the first magnetic group assembly are attracted to each other, and the third magnetic yoke and the second magnetic group assembly are attracted to each other, thereby providing a restoring force for the second base and the first base in the first direction or the second direction, i.e. the force required to return to the initial position.

[0025] In some implementations, the first magnetic yoke includes a first magnetic plate and a first protrusion, the first magnetic plate has a first surface facing the first coil, and the first protrusion is disposed on the first surface and protrudes from the first surface.

[0026] By adopting the above technical solution, the first protrusion protrudes from the first surface facing the first coil, which is conducive to increasing the driving force generated when the first coil is energized, and also reduces the influence of the attractive force and the restoring force, thereby meeting the driving force required for long-stroke optical image stabilization of a large-aperture or large-mass lens.

[0027] In some implementations, the first surface is a plane, the first protrusion is located at a middle position of a length direction of the first magnetic plate, and the length direction of the first magnetic plate is parallel to the second direction.

[0028] By adopting the above technical solution, the first protrusion is disposed on the first surface in the form of a plane and at the middle position, which is conducive to increasing the driving force generated when the first coil is energized, and also reduces the influence of the attractive force and the restoring force, thereby meeting the driving force required for long-stroke optical image stabilization of a large-aperture or large-mass lens.

[0029] In some implementations, when the first coil assembly is fixed to the first base, the first magnetic yoke is embedded in the interior of the first base.

[0030] Or, when the first coil assembly is fixed to the second base, the first magnetic yoke is embedded in the interior of the second base.

[0033] By adopting the above technical solution, the second protrusion protrudes from the second surface facing the second coil, which is conducive to increasing the driving force generated when the second coil is energized, and also reduces the influence of the attractive force and the restoring force, thereby meeting the driving force required for long-stroke optical image stabilization of a large-aperture or large-mass lens.

[0034] In some implementations, the second surface is a plane, the second protrusion is located at a middle position of a length direction of the second magnetic plate, and the length direction of the second magnetic plate is parallel to the first direction.

[0035] By adopting the technical scheme, the second protrusion is arranged on the second surface in a planar manner and at the middle position, so that the driving force generated when the second coil is electrified can be increased, and the influence of the attraction force and the restoring force can be reduced, thereby meeting the driving force required when the large-aperture or large-mass lens performs long-stroke optical image stabilization.

[0036] In some implementations, when the second coil assembly is fixed to the first base, the third flux guide yoke is embedded in the interior of the first base.

[0037] Or, when the second coil assembly is fixed to the second base, the third flux guide yoke is embedded in the interior of the second base.

[0042] By adopting the technical scheme, the intermediate support is clamped between the first base and the second base, which is beneficial to decouple the movement of the second base relative to the first direction and the movement of the second base in the second direction, so that the mutual influence between them is reduced or eliminated, thereby improving the overall performance, stability or flexibility of the driving device and improving the effect of long-stroke optical image stabilization of the large-aperture or large-mass lens.

[0043] In some implementations, the driving device further includes a first roller and a second roller, the first roller is located between the intermediate support and the first base.

Of course, the electronic device can also be other devices that need optical image stabilization function and compensate for camera module jitter, such as a drone, a smart robot.

[0183] The mobile phone can be a straight mobile phone or a folding mobile phone. Exemplarily, the electronic device of the embodiments of the present application is described by taking a mobile phone as an example. The electronic device further comprises a display screen 102; as shown in FIG. 2, in some embodiments, the shell 101 comprises a middle frame (not shown), a bezel 103 and a back cover 104. The bezel 103 and the back cover 104 can be an integrally formed structure or can be formed into an integrated structure by assembly. The display screen 102 and the back cover 104 are respectively connected with the bezel 103. The camera module 200 can be mounted on the back of the electronic device and used as a rear camera, or the camera module 200 can be used as a front camera of the electronic device, which is not specifically limited here.

[0184] For ease of description, as shown in FIGS. 1 and 2, the length direction of the electronic device can be defined as the A-A direction, the width direction of the electronic device can be defined as the B-B direction, and the thickness direction of the electronic device, the width direction of the electronic device and the length direction of the electronic device are perpendicular to each other.

[0186] Fig. 3 is a structural schematic diagram of the camera module 200 provided in the embodiments of the present application. As shown in Fig. 3, in some embodiments, the camera module 200 includes a driving device 201, a lens 202 and a photosensitive element (not shown), the lens 202 is mounted on the driving device 201; the driving device 201 can also be referred to as a motor, and the motor can be a voice coil motor; the photosensitive element is located on the image side of the lens 202, and the light reflected by the photographed object passes through the lens 202 to generate an optical image and is projected onto the photosensitive surface of the photosensitive element, and the photosensitive element converts the optical image into an electrical signal, i.e., an analog image signal, and transmits the analog image signal to a processor. The photosensitive element (also referred to as an image sensor) is a kind of semiconductor chip, and the surface thereof contains hundreds of thousands to millions of photodiodes, which will generate electric charges when irradiated by light. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS). The CCD is made of a high-sensitivity semiconductor material and can convert light into electric charges. The charge coupled device is composed of many photosensitive units, usually in units of millions of pixels. When the surface of the photosensitive element is irradiated by light, each photosensitive unit will reflect electric charges on the component, and the signals generated by all the photosensitive units are added together to form a complete picture. The driving device 201 in the embodiments of the present application can be applied to a lens 202 with a large aperture and / or a relatively heavy weight, and it can also realize optical image stabilization of a large-aperture and / or large-mass lens with a long stroke (stroke greater than 300 pm). It can be understood that the driving device in the embodiments of the present application is not limited to electronic devices, but can also be applied to other devices or apparatuses that require optical image stabilization function and compensate for camera module jitter. In some embodiments, when the camera module 200 is used as a rear camera, the rear cover 104 of the shell can be provided with a lens hole, and the lens 202 is arranged opposite to the lens hole, so that the external light enters the lens 202 through the lens hole; a transparent cover can be mounted at the lens hole, and the material of the transparent cover can be glass or plastic.

[0188] In an implementation, a motor-driven optical device with optical image stabilization function moves in two directions to compensate for the shake generated during shooting, thereby increasing the clarity of the camera module. Generally, the motor includes a driving assembly, and the driving assembly includes a coil and a magnet. The motor is provided with the driving assembly on both sides of the optical device in one direction, and the motor is also provided with the driving assembly on both sides of the optical device in another direction, so that the driving assembly is provided in four directions of the optical device. However, as the requirement for pixels is getting higher and higher, the volume of the lens of the camera module is getting larger and larger, so that the mass of the lens is increased. In addition, in order to meet the shooting quality, the aperture of the camera module is also getting larger and larger, and long-stroke optical stabilization is also required for the large-mass lens, wherein the long-stroke refers to the maximum distance of the lens offset from the initial position being greater than 300 μm. However, due to the limitation of the installation space, the size of the motor is limited, and when the large-aperture or large-mass lens with better driving optical performance is driven for long-stroke optical stabilization, the driving force is insufficient.

[0189] Therefore, the embodiment of the present application provides a driving device 201 to solve the problem that the driving assembly is provided in four directions of the optical device in the related embodiment. The driving device 201 provided by the embodiment of the present application is described in detail as follows.

By making the length of the driving device 201 greater than the width of the driving device 201, the size of the driving device 201 in the second direction is smaller than the size in the first direction, which is conducive to realizing that the driving device 201 can have a smaller size in the second direction, and the first driving assembly 305 and the second driving assembly 306 can be arranged in the first direction with appropriate driving force, so as to meet the needs of driving the to-be-driven device, such as meeting the driving force required when the large-aperture or large-mass lens 202 performs long-stroke optical anti-shake. For example, the driving device 201 is in the shape of a cuboid, the first base 301 is in the shape of a cuboid, and the second base 302 is in the shape of a cuboid; the length of the first base 301 is greater than the width of the first base 301, and the length of the second base 302 is greater than the width of the second base 302; the length direction of the first base 301 is parallel to the length direction of the second base 302, and the width direction of the first base 301 is parallel to the width direction of the second base 302; the thickness direction of the first base 301 is parallel to the thickness direction of the second base 302; the first direction is parallel to the length direction of the second base 302, and the second direction is parallel to the width direction of the second base 302. After the camera module 200 is installed in the shell, the length direction of the camera module 200 is parallel to the width direction of the electronic device, so as to reduce the space occupied by the camera module in the length direction of the electronic device; it can be understood that, according to the installation requirement, the length direction of the camera module 200 can also be arranged to be parallel to the length direction of the electronic device, so as to reduce the space occupied by the camera module 200 in the width direction of the electronic device.

[0198] In combination with FIGS. 5 and 6, in the first direction, the hole structure 307 is located between the first mounting side 347 and the second mounting side 348. The hole structure 307 has two opposite sides in the first direction, namely the first mounting side 347 and the second mounting side 348. For example, the hole structure 307 is a circular hole, and the two ends of the diameter of the circular hole parallel to the first direction are respectively referred to as the first end point E and the second end point F; two sides are arranged along the length direction of the second base 302 (parallel to the first direction), and the two opposite sides are respectively referred to as the first side 309 and the second side 310; in the first direction, the first end point E and the first side 309 are located on one side of the hole center O of the circular hole, and the second end point F and the second side 310 are located on the other side of the hole center O of the circular hole; the straight line parallel to the second direction passing through the first end point E is the first straight line L1, and the straight line parallel to the second direction passing through the second end point F is the second straight line L2; the region extending from the first straight line L1 to the direction of the first side 309 is the first mounting side 347 of the mounting area 303, and the region extending from the second straight line L2 to the direction of the second side 310 is the second mounting side 348 of the mounting area 303. The first mounting side 347 and the second mounting side 348 are oppositely arranged, and the regions of the mounting sub-area 308 on the opposite sides in the first direction are respectively the first mounting side 347 and the second mounting side 348. In this way, only the first driving assembly 305 and the second driving assembly 306 need to be arranged on the mounting side 304, so as to reduce the space occupied by the first driving assembly 305 and the second driving assembly 306 in the second direction of the driving device 201. In at least one embodiment, at least one of the opposite sides of the hole structure 307 in the first direction is provided with a driving assembly, and the opposite sides of the hole structure 307 in the second direction are not provided with a driving assembly, that is, the driving assemblies are arranged on the opposite sides of the lens 202 in the first direction, and the driving assemblies are not arranged on the opposite sides of the lens in the second direction. In this way, the driving assemblies are asymmetrically distributed in the driving device 201. Compared with the embodiments in which driving assemblies are arranged in four directions of the optical device, the embodiment is beneficial to reducing the size of the driving device 201 in the second direction, so that the driving device 201 can adapt to smaller asymmetric space sizes in electronic equipment, and the driving device 201 can drive a large-aperture, large-mass lens 202 with better optical performance for optical anti-shake.

[0199] It should be noted that in some other possible embodiments, when the hole structure 307 is a circular hole, the two ends of a chord of the circular hole parallel to the first direction can also be referred to as the first end point E and the second end point F respectively, and the first mounting side 347 and the second mounting side 348 of the mounting side 304 are defined according to the above description. In addition, when the hole structure 307 is a rectangular hole, the two opposite sides of the rectangular hole in the first direction are the first mounting side 347 and the second mounting side 348 of the mounting side 304 respectively. It can be understood that although in the embodiments of the present application, the two opposite sides of the hole structure 307 in the second direction are not provided with the first driving assembly 305 or the second driving assembly 306, so as to reduce the overall size of the driving device 201 in the second direction, and meet the requirement of driving force of the large-aperture or large-mass lens 202 for long-stroke optical anti-shake. However, in some other possible application scenarios, the two opposite sides of the hole structure 307 in the second direction can also be provided with the first driving assembly 305 or the second driving assembly 306.

[0200] In some embodiments, as shown in FIGS. 5 and 6, the first driving assembly 305 can be completely located on the mounting side 304, and the second driving assembly 306 can be completely located on the mounting side 304. In this way, the size of the driving device 201 in the second direction can be reduced, so that the driving device 201 can be adapted to smaller asymmetric space size in the electronic device, and the driving device 201 can drive the large-aperture, large-mass lens 202 with better optical performance for optical anti-shake.

[0201] In some embodiments, one of the first mounting side 347 and the second mounting side 348 is provided with the first driving assembly 305, and the other is provided with the second driving assembly 306; or, at least one of the first mounting side 347 and the second mounting side 348 is provided with the first driving assembly 305 and the second driving assembly 306. The distribution design of the first driving assembly 305 and the second driving assembly 306 on the mounting side 304 can meet different requirements, such as the balance of the movement of the second base 302 in different directions, the balance of the overall mass of the driving device 201, the requirement of the driving force of the driving device 201 in different directions, the installation position of the driving device 201 in the electronic device, and the space requirement in a single direction in the electronic device, etc.

[0202] When one of the first mounting side 347 and the second mounting side 348 is provided with the first driving assembly 305 and the other is provided with the second driving assembly 306, the driving device 201 can include one first driving assembly 305 and one second driving assembly 306. In an embodiment, as shown in FIG. 6, the first driving assembly 305, the hole structure 307 and the second driving assembly 306 are arranged in the first direction in sequence, so that the distribution design of the first driving assembly 305 and the second driving assembly 306 on the mounting side 304 can meet the installation position of the driving device 201 in the electronic device and the space requirement in a single direction in the electronic device, etc. For example, the length side of the driving device 201 is parallel to the length direction of the driving device 201, and the width side of the driving device 201 is parallel to the width direction of the driving device 201; in the first direction, the distance D2 between the center of the hole structure 307 and one width side of the driving device 201 is greater than the distance D1 between the center of the hole structure 307 and the other width side of the driving device 201, so that the center of the hole structure 307 does not coincide with the center of the second base 302, and the hole structure 307 is designed eccentrically relative to the center of the second base 302, so that the installation position of the driving device 201 in the electronic device and the space requirement in a single direction in the electronic device can be met, and the driving device 201 can adapt to different installation occasions; because the first driving assembly 305 and the second driving assembly 306 are placed in different ways, in FIG. 6, the area occupied by the first mounting side 347 of the second base 302 on which the first driving assembly 305 is located can be smaller than the area occupied by the second mounting side 348 on which the second driving assembly 306 is located.

[0203] When at least one of the first mounting side 347 and the second mounting side 348 is provided with the first driving assembly 305 and the second driving assembly 306, and the driving device 201 includes one first driving assembly 305 and one second driving assembly 306, at this time, one of the first mounting side 347 and the second mounting side 348 is provided with the first driving assembly 305 and the second driving assembly 306, and the other is not provided with the first driving assembly 305 and the second driving assembly 306, so that the distribution design of the first driving assembly 305 and the second driving assembly 306 on the mounting side 304 can meet the installation position of the driving device 201 in the electronic device and the space requirement in a single direction in the electronic device, etc.

[0204] In another embodiment, FIG. 7 is a structural schematic diagram of a second positional relationship among the first driving assembly 305, the second driving assembly 306 and the hole structure 307 according to the embodiments of the present application. As shown in FIG. 7, the second mounting side 348 is provided with one first driving assembly 305 and one second driving assembly 306, the first mounting side 347 is not provided with the first driving assembly 305 and the second driving assembly 306, and the hole structure 307, the first driving assembly 305 and the second driving assembly 306 are arranged in the first direction in sequence. For example, in the first direction, the distance D2 between the center of the hole structure 307 and one width side of the driving device 201 is greater than the distance D1 between the center of the hole structure 307 and the other width side of the driving device 201, so that the center of the hole structure 307 does not coincide with the center of the second base 302, and the hole structure 307 is designed to be eccentric relative to the center of the second base 302, so as to meet the installation position of the driving device 201 in the electronic device and the space requirement in a single direction in the electronic device, and the driving device 201 can adapt to different installation occasions. It should be noted that in some other possible embodiments, one of the first mounting side 347 and the second mounting side 348 can be provided with one or more first driving assemblies 305 and one or more second driving assemblies 306, for example, 2-3 first driving assemblies 305 and 2-3 second driving assemblies 306, and the other can not be provided with the first driving assembly 305 and the second driving assembly 306.

[0205] In yet another embodiment, FIG. 8 is a structural schematic diagram of a third positional relationship among the first driving assembly 305, the second driving assembly 306 and the hole structure 307 according to the embodiments of the present application. As shown in FIG. 8, the second mounting side 348 is provided with one first driving assembly 305 and one second driving assembly 306, and the first mounting side 347 is not provided with the first driving assembly 305 and the second driving assembly 306. The hole structure 307, the second driving assembly 306 and the first driving assembly 305 are arranged in the first direction in sequence. For example, in the first direction, the distance D2 between the center of the hole structure 307 and one width side of the driving device 201 is greater than the distance D1 between the center of the hole structure 307 and the other width side of the driving device 201, so that the center of the hole structure 307 does not coincide with the center of the second base 302, and the hole structure 307 is designed to be eccentric relative to the center of the second base 302, so as to meet the installation position of the driving device 201 in the electronic device and the space requirement in a single direction in the electronic device, so that the driving device 201 can adapt to different installation occasions. It should be noted that in some other possible embodiments, one of the first mounting side 347 and the second mounting side 348 can be provided with one or more first driving assemblies 305 and one or more second driving assemblies 306, and the other can be provided with one first driving assembly 305 or one second driving assembly 306.

[0206] When at least one of the first mounting side 347 and the second mounting side 348 is provided with the first driving assembly 305 and the second driving assembly 306, and the driving device 201 includes two first driving assemblies 305 and two second driving assemblies 306, at this time, the first mounting side 347 is provided with one first driving assembly 305 and one second driving assembly 306; and the second mounting side 348 is provided with one first driving assembly 305 and one second driving assembly 306.

[0207] In still another embodiment, FIG. 9 is a structural schematic diagram of a fourth positional relationship among the first driving assembly 305, the second driving assembly 306 and the hole structure 307 according to an embodiment of the present application. As shown in FIG. 9, the whole formed by the first driving assembly 305 and the second driving assembly 306 located at the first mounting side 347 is arranged in a center-symmetrical manner with respect to the whole formed by the first driving assembly 305 and the second driving assembly 306 located at the second mounting side 348. In this way, the first driving assembly 305 and the second driving assembly 306 are distributed on the mounting side 304, which can meet the balance of the second base 302 in different directions, the balance of the overall mass of the driving device 201, the requirement of the driving force of the driving device 201 in different directions, the installation position of the driving device 201 in the electronic equipment and the space requirement of the driving device 201 in a single direction in the electronic equipment, etc. For example, as shown in FIG. 9, the first driving assembly 305 and the second driving assembly 306 located at the first mounting side 347 are arranged in the second direction, and the first driving assembly 305 and the second driving assembly 306 located at the second mounting side 348 are arranged in the second direction. The line between the first driving assembly 305 located at the first mounting side 347 and the first driving assembly 305 located at the second mounting side 348 intersects with the line between the second driving assembly 306 located at the first mounting side 347 and the second driving assembly 306 located at the second mounting side 348, so that the first driving assembly 305 located at the first mounting side 347 and the first driving assembly 305 located at the second mounting side 348 are arranged diagonally, and the second driving assembly 306 located at the first mounting side 347 and the second driving assembly 306 located at the second mounting side 348 are arranged diagonally, thereby ensuring the stability of the movement of the second base 302.

[0208] It should be noted that in some other possible embodiments, among the first mounting side 347 and the second mounting side 348, the first driving assembly 305 and the second driving assembly 306 can be arranged in one of them, and the other one can only have the first driving assembly 305 or only have the second driving assembly 306. Specifically, it can be designed according to the requirement. In still some possible embodiments, the whole formed by the first driving assembly 305 and the second driving assembly 306 located at the first mounting side 347 can be arranged in an axial-symmetrical manner with respect to the whole formed by the first driving assembly 305 and the second driving assembly 306 located at the second mounting side 348.

[0209] Figure 10 is an exploded view of the driving device 201 according to an embodiment of the present application. As shown in Figure 10, in the embodiment of the present application, the first driving assembly 305 includes a first coil assembly 312 and a first magnetic assembly 313, and the first coil assembly 312 and the first magnetic assembly 313 cooperate with each other. One of the first coil assembly 312 and the first magnetic assembly 313 is fixed on the first base 301, and the other is fixed on the second base 302. The second driving assembly 306 includes a second coil assembly 314 and a second magnetic assembly 315, and the second coil assembly 314 and the second magnetic assembly 315 cooperate with each other. One of the second coil assembly 314 and the second magnetic assembly 315 is fixed on the first base 301, and the other is fixed on the second base 302. By using the cooperation of the first coil assembly 312 and the first magnetic assembly 313, the linear motion of the second base 302 relative to the first base 301 in the first direction can be achieved. By using the cooperation of the second coil assembly 314 and the second magnetic assembly 315, the linear motion of the second base 302 relative to the first base 301 in the second direction can be achieved, thereby achieving optical anti-shake of the optical device. The fixed positions of the first coil assembly 312 and the first magnetic assembly 313 (i.e., on the first base 301 or on the second base 302) can be designed according to needs. The fixed positions of the second coil assembly 314 and the second magnetic assembly 315 (i.e., on the first base 301 or on the second base 302) can be designed according to needs, thereby improving the degree of freedom of design.

[0210] For example, as shown in Figure 10, the first coil assembly 312 is fixed on the first base 301, and the first magnetic assembly 313 is fixed on the second base 302. The second coil assembly 314 is fixed on the first base 301, and the first magnetic assembly 313 is fixed on the second base 302. In this way, the main board of the electronic device can be electrically connected to the first coil assembly 312 and the second coil assembly 314, respectively, to control the driving device 201.

[0211] It should be noted that in some other possible embodiments, the first coil assembly 312 can be fixed on the second base 302, and the first magnetic assembly 313 can be fixed on the first base 301. The second coil assembly 314 can be fixed on the second base 302, and the first magnetic assembly 313 can be fixed on the first base 301.

[0212] Referring to FIG. 10, in the embodiment of the present application, the first coil assembly 312 includes the first coil 316 and the first magnetic yoke 317, and the first magnetic assembly 313 includes the first magnet 318 and the second magnetic yoke 319; in the thickness direction of the driving device 201, the first coil 316 is located between the first magnetic yoke 317 and the first magnetic assembly 313, and the first magnet 318 is located between the second magnetic yoke 319 and the first coil assembly 312. The second coil assembly 314 includes the second coil 320 and the third magnetic yoke 321, and the second magnetic assembly 315 includes the second magnet 322 and the fourth magnetic yoke 323; in the thickness direction of the driving device 201, the second coil 320 is located between the third magnetic yoke 321 and the second magnetic assembly 315, and the second magnet 322 is located between the fourth magnetic yoke 323 and the second coil assembly 314. In this way, the first magnetic yoke 317 and the first magnetic assembly 313 are attracted to each other, and the third magnetic yoke 321 and the second magnetic assembly 315 are attracted to each other, thereby providing an attractive force in the thickness direction of the driving device 201 for the first base 301 and the second base 302 to be attracted to each other, so that the first base 301 and the second base 302 can be combined together in the thickness direction of the driving device 201, and the distance between the two in the thickness direction of the driving device 201 is maintained. When the first coil 316 is energized, the first coil 316 and the first magnetic assembly 313 interact with each other to achieve linear motion of the second base 302 relative to the first base 301 in the first direction; similarly, when the second coil 320 is energized, the second coil 320 and the second magnetic assembly 315 interact with each other to achieve linear motion of the second base 302 relative to the first base 301 in the second direction, thereby achieving optical anti-shake of the optical device; after the second base 302 moves relative to the first base 301 in the first direction or the second direction, and the two are offset in the first direction or the second direction, the first magnetic yoke 317 and the first magnetic assembly 313 are attracted to each other, and the third magnetic yoke 321 and the second magnetic assembly 315 are attracted to each other, thereby providing a restoring force in the first direction or the second direction for the second base 302 and the first base 301, i.e., the force required to return to the original position.

[0213] For example, as shown in FIG. 10, in the thickness direction of the driving device 201, the first coil 316 is located between the first magnetic yoke 317 and the first magnet 318, and the second coil 320 is located between the third magnetic yoke 321 and the second magnet 322. The first coil 316 and the second coil 320 are electrically connected to the main board, respectively. The first coil assembly 312 further comprises a first sensing element 324, which detects the position information of the first magnetic assembly 313 by sensing the change of the feedback magnetic flux, so that the driving device 201 can control the movement amount of the second base 302 relative to the first base 301 in the first direction. The second coil assembly 314 further comprises a second sensing element 325, which detects the position information of the second magnetic assembly 315 by sensing the change of the feedback magnetic flux, so that the driving device 201 can control the movement amount of the second base 302 relative to the first base 301 in the second direction; thereby realizing the accurate control of the position of the lens 202 and realizing the anti-shake of the lens 202. The first sensing element 324 can be a Hall sensor or a tunnel magnetoresistance sensor; the second sensing element 325 can be a Hall sensor or a tunnel magnetoresistance sensor.

[0214] For example, as shown in FIG. 10, the first coil assembly 312 comprises two first magnetic yokes 317, which are respectively arranged corresponding to the two different surfaces of the first coil 316, so as to improve the driving force. The first magnetic yoke 317 can be embedded in the interior of the first base 301. For example, the material of the first base 301 is plastic, and the first magnetic yoke 317 is embedded in the interior of the first base 301 by insert injection molding, so as to simplify the assembly and ensure the stability of the fixed position of the first magnetic yoke 317. It can be understood that when the first magnetic yoke 317 is embedded in the first base 301 by insert injection molding, the first magnetic yoke 317 can be completely embedded in the first base 301, or a part of the first magnetic yoke 317 can be embedded in the first base 301, and the other part can be exposed on the surface of the first base 301. The first magnet 318 can be provided with two pieces. One piece of the first magnet 318 has the N pole facing the second base 302 and the S pole facing the first coil 316; the other piece of the first magnet 318 has the S pole facing the second base 302 and the N pole facing the first coil 316. It can be understood that the two first magnets 318 can be an integral structure or a split structure. It should be noted that in some other possible embodiments, the first magnetic yoke 317 can also be fixed to the surface of the first base 301 by adhesion.

[0215] Exemplarily, referring to FIG. 10, the second coil assembly 314 includes two third flux concentrating yokes 321, which are respectively arranged corresponding to the two different surfaces of the second coil 320, so as to improve the driving force. The third flux concentrating yokes 321 can be embedded in the interior of the first base 301. For example, the first base 301 is made of plastic, and the third flux concentrating yokes 321 are embedded in the interior of the first base 301 by insert injection molding, so as to simplify the assembly and ensure the stability of the fixed position of the third flux concentrating yokes 321. It can be understood that when the third flux concentrating yokes 321 are embedded in the first base 301 by insert injection molding, the third flux concentrating yokes 321 can be completely embedded in the first base 301, or a part of the third flux concentrating yokes 321 can be embedded in the first base 301, and the other part can be exposed on the surface of the first base 301. The second magnet 322 can be provided with two pieces. One of the second magnets 322 has the N pole facing the second base 302 and the S pole facing the second coil 320. The other of the second magnets 322 has the S pole facing the second base 302 and the N pole facing the second coil 320. It can be understood that the two second magnets 322 can be an integral structure or a split structure. It should be noted that in some other possible embodiments, the third flux concentrating yokes 321 can also be fixed to the surface of the first base 301 by adhesion.

[0216] Referring to FIG. 10, the driving device 201 further includes an intermediate support 326, which is located between the first base 301 and the second base 302 in the thickness direction of the driving device 201. The intermediate support 326 is configured to move together with the second base 302 relative to the first base 301 in the second direction. The intermediate support 326 is movably connected with the second base 302, so that the second base 302 can move relative to the intermediate support 326 in the first direction. By clamping the intermediate support 326 between the first base 301 and the second base 302, the decoupling of the movement of the second base 302 relative to the first direction and the movement of the second base 302 in the second direction is facilitated, so that the mutual influence between them is reduced or eliminated, thereby improving the overall performance, stability or flexibility of the driving device 201, and improving the effect of long-stroke optical image stabilization of the large-aperture or large-mass lens 202. Exemplarily, the intermediate support 326 includes a frame structure, i.e., the intermediate support 326 adopts a closed quadrilateral, such as a rectangle, formed by four bars 346 connected end to end. Of course, the intermediate support 326 can also be a U-shaped structure formed by three bars 346 connected in sequence.

[0217] Referring to FIG. 10, the first roller 327 is arranged between the intermediate support 326 and the first base 301 to enable relative movement between the intermediate support 326 and the first base 301 in the second direction; the second roller 328 is arranged between the intermediate support 326 and the second base 302 to enable relative movement between the intermediate support 326 and the second base 302 in the first direction. Since the intermediate support 326 is adopted, the first roller 327 can be conveniently arranged between the intermediate support 326 and the first base 301, and the second roller 328 can be conveniently arranged between the intermediate support 326 and the second base 302, and the influence between the movement of the first roller 327 and the movement of the second roller 328 can be reduced or eliminated, thereby improving the overall performance, stability or flexibility of the driving device 201, and improving the effect of long-stroke optical anti-shake of the large-aperture or large-mass lens 202. For example, the driving device 201 includes a plurality of first rollers 327, for example, the driving device 201 includes 4 first rollers 327, and the 4 first rollers 327 are located at the four corners of the first base 301; the driving device 201 includes a plurality of second rollers 328, for example, the driving device 201 includes 4 second rollers 328, and the 4 second rollers 328 are located at the four corners of the second base 302, so as to realize the smoothness of the movement of the first base 301 relative to the second base 302 in the first direction and the second direction. It should be noted that in some other possible embodiments, the number of first rollers 327 is not limited to 4, but can also be 6 or 8, etc.; the number of second rollers 328 is not limited to 4, but can also be 6 or 8, etc. Since the first magnetic yoke 317 is attracted to the first magnetic assembly 313, and the third magnetic yoke 321 is attracted to the second magnetic assembly 315, the first roller 327 can be pressed between the first base 301 and the intermediate support 326, and the second roller 328 can be pressed between the second base 302 and the intermediate support 326, so that the first base 301 and the intermediate support 326 can move relative to each other, and the intermediate support 326 and the second base 302 can move relative to each other, thereby realizing the decoupling anti-shake effect of the driving device 201 in the first direction and the second direction, and reducing the risk of crosstalk in the optical anti-shake process.

[0218] Referring to FIG. 10, the first roller 327 is a ball bearing; the second roller 328 is a ball bearing. The ball bearing is used in the form of a ball to provide low-friction support and guidance during movement, reduce friction and vibration, provide precise movement control, and ensure smooth displacement.

[0219] It should be noted that in some other possible embodiments, the first roller 327 can be a slide shaft; and the second roller 328 can be a slide shaft. In this way, the slide shafts can ensure stability and accuracy in long-stroke movement. It can be understood that in one drive device 201, the type of the first roller 327 selected can be the same as the type of the second roller 328 selected, i.e., both are selected to be a ball bearing; or both are selected to be a slide shaft; or one is selected to be a ball bearing and the other is selected to be a slide shaft. The specific selection can be made according to actual needs.

For example, the orthographic projection of the second protrusion 344 in a second specified plane is a quadrilateral, such as a square or a rectangle. The second specified plane is perpendicular to the thickness direction of the driving device 201, and the second specified plane can be any plane perpendicular to the thickness direction of the driving device 201.

When 3D printing is used, the material of the shell 300, the material of the moving frame 301 and the material of the intermediate support 318 are not limited to plastic, but can also be ceramic or non-magnetic metal, etc. In addition, in some other possible embodiments, the shell 300 can also be provided with the rib structure 319, such as the rib structure 319 provided on the outer shell 315 and / or the base 314.

[0246] Fig. 25 is an exploded view of the driving device 201 according to an embodiment of the present application. As shown in Figs. 24 and 25, the driving device 201 further comprises a first roller 320 and a second roller 321. The first roller 320 is located between the base 314 and the intermediate support 318, and the second roller 321 is located between the intermediate support 318 and the moving frame 301. Thanks to the intermediate support 318, the first roller 320 can be conveniently arranged between the intermediate support 318 and the base 314, and the second roller 321 can be conveniently arranged between the intermediate support 318 and the moving frame 301. In this way, the influence between the movement of the first roller 320 and the movement of the second roller 321 can be reduced or eliminated, thereby improving the overall performance, stability or flexibility of the driving device 201, and improving the effect of long-stroke optical image stabilization for a lens 202 with a large aperture or a large mass. In addition, the first coil assembly 308 is biased toward the first magnetic assembly 307 on the first mounting surface in the thickness direction of the driving device 201, and the second coil assembly 310 is biased toward the second magnetic assembly 309 on the first mounting surface in the thickness direction of the driving device 201. In this way, the second roller 321 can be kept between the intermediate support 318 and the moving frame 301, and the first roller 320 can be kept between the intermediate support 318 and the base 314, so as to ensure that the moving frame 301 can move relative to the intermediate support 318, and the intermediate support 318 and the moving frame 301 can move together relative to the base 314.

[0247] For example, the driving device 201 comprises a plurality of first rollers 320 and a plurality of second rollers 321. For example, the driving device 201 comprises four first rollers 320, which are located at four corners of the base 314, and the driving device 201 comprises four second rollers 321, which are located at four corners of the moving frame 301. In this way, the stability of the movement of the base 314 relative to the moving frame 301 in the first direction and the second direction is achieved. It should be noted that in some other possible embodiments, the number of first rollers 320 is not limited to four, but can also be six or eight, etc. The number of second rollers 321 is not limited to four, but can also be six or eight, etc.

[0248] In some embodiments, the first roller 320 is a ball bearing, and the second roller 321 is a ball bearing. In this way, low-friction support and guidance are provided during movement, friction and vibration are reduced, precise movement control is provided, and smooth displacement is ensured. For example, the ball bearing has a spherical structure, so that the flexibility of the movement of the moving frame 301 is improved.

[0249] It should be noted that in some other possible embodiments, the first roller 320 can be a slide shaft, and the second roller 321 can be a slide shaft; the form of slide shaft can ensure stability and accuracy in long-stroke movement. It can be understood that in one drive device 201, the type of the first roller 320 selected and the type of the second roller 321 selected can be the same, or can be different, i.e., both are selected as a ball bearing; or both are selected as a slide shaft; or one is selected as a ball bearing and the other is selected as a slide shaft; the specific selection can be made according to actual needs.

[0250] In combination with FIGS. 24 and 25, in some embodiments, the first coil assembly 308 includes a first coil 322 having a coil hole 324 and a first magnetic yoke 323; the first magnetic assembly 307 includes a first magnet 325. The presence of the coil hole 324 of the first coil 322 enables the magnetic field to act more concentratedly on a certain part in the first coil 322; this design also helps to reduce energy loss and improve the overall performance of the system. The first coil 322 corresponds to the first coil 316 in the first embodiment. The first magnetic yoke 323 corresponds to the first magnetic yoke 317 in the first embodiment. The first magnet 325 corresponds to the first magnet 318 in the first embodiment.

[0251] In combination with FIGS. 24 and 25, in some embodiments, the second coil assembly 310 includes a second coil 326 having a coil hole 324 and a second magnetic yoke 327; the second magnetic assembly 309 includes a second magnet 328. The presence of the coil hole 324 enables the magnetic field to act more concentratedly on a certain part in the second coil 326; this design also helps to reduce energy loss and improve the overall performance of the system. The second magnetic yoke 327 corresponds to the third magnetic yoke 321 in the first embodiment. The second coil 326 corresponds to the second coil 320 in the first embodiment.

[0252] Referring to FIGS. 24 and 25, the driving device 201 further comprises a third magnetic yoke 329. The third magnetic yoke 329 is arranged on the side of the first magnetic element 325 on the mounting surface 306 of the base 314, which is opposite to the first coil assembly 308. The third magnetic yoke 329 is also arranged on the side of the second magnetic element 328 on the mounting surface 306 of the base 314, which is opposite to the first coil assembly 308. The third magnetic yoke 329 guides and concentrates the magnetic field of the first magnetic element 325 and the second magnetic element 328. For example, the third magnetic yoke 329 can be embedded in the base 314, so that the third magnetic yoke 329 does not occupy the space in the thickness direction of the driving device 201. For example, the third magnetic yoke 329 can be embedded in the base 314 by insert molding. It can be understood that the third magnetic yoke 329 can also be arranged on the base 314 in other ways, for example, a recess is formed on the base 314, and the third magnetic yoke 329 is arranged in the recess. In addition, the side of the first magnetic element 325 on the mounting surface 306 of the housing 315, which is opposite to the first coil assembly 308, can also be provided with a third magnetic yoke 329. The side of the second magnetic element 328 on the mounting surface 306 of the housing 315, which is opposite to the second coil assembly 310, can also be provided with a third magnetic yoke 329. The third magnetic yoke 329 corresponds to the second magnetic yoke 319 and the fourth magnetic yoke 323 in the first embodiment.

[0253] Referring to FIGS. 24 and 25, the driving device 201 further comprises a first circuit board 330. The first circuit board 330 is electrically connected to the main board. The first circuit board 330 can be a hard circuit board. The first circuit board 330 is fixed to the housing 300, for example, the first circuit board 330 is fixedly connected to the housing 315. The housing 315 has a wire passing hole 331. The wire passing hole 331 is used to facilitate the electrical connection between the first coil 322 and the second coil 326 and the first circuit board 330. The first coil 322 and the first circuit board 330 can be connected by a flexible circuit board, which facilitates the movement of the moving frame 301. The first coil assembly 308 further comprises a first sensing element 332. The first sensing element 332 detects the position information of the first magnetic assembly 307 relative to the first coil assembly 308 by sensing the change of the feedback magnetic flux. The driving device 201 can control the movement amount of the moving frame 301 relative to the base 314 in the first direction, so as to correct and feedback the position of the lens 202. For example, the first sensing element 332 can be a Hall sensor or a tunnel magnetoresistance sensor. The first sensing element 332 is fixed to the moving frame 301, and the first sensing element is located in the coil hole 324 of the first coil 322.

[0254] As shown in FIGS. 24 and 25, the second coil 326 and the first circuit board 330 can be connected through a flexible circuit board, which facilitates the movement of the moving frame 301. The second coil assembly 310 further includes a second sensing element 333, which detects the position information of the second magnetic assembly 309 relative to the second coil assembly 310 by sensing the change of the feedback magnetic flux, so that the driving device 201 can control the movement amount of the moving frame 301 relative to the base 314 in the second direction to correct and feedback the position of the lens 202; thereby achieving accurate control of the position of the lens 202 and realizing the anti-shake of the lens 202. For example, the second sensing element 333 can be a Hall sensor or a tunnel magnetoresistance sensor, and the second sensing element 333 is fixed on the moving frame 301 and located in the coil hole 324 of the second coil 326. It should be noted that the second coil 326 and the first circuit board 330 can also be connected through other flexible connection modes, such as a flexible flat cable. The second sensing element 333 corresponds to the second sensing element 325 in the first embodiment.

[0255] For the convenience of description and distinction between the two mounting surfaces 306, the mounting surface 306 located on the base 314 is referred to as the first mounting surface, and the mounting surface 306 located on the housing 315 is referred to as the second mounting surface.

[0256] As shown in FIGS. 24 and 25, in some embodiments, the moving frame 301 is a plate-shaped structure, which facilitates the installation of the first coil assembly 308 and the second coil assembly 310 for the installation of the driving device. In the thickness direction of the driving device 201, the distance between the first coil assembly 308 and the first magnetic assembly 307 located on the first mounting surface is less than the distance between the first coil assembly 308 and the first magnetic assembly 307 located on the second mounting surface; and the first coil assembly 308 is located on the side of the moving frame 301 facing the first mounting surface. In this way, the first coil assembly 308 is biased towards the first magnetic assembly 307 on the first mounting surface in the thickness direction of the driving device 201, so that the first magnetic yoke 323 is attracted to the first magnet 325 on the first mounting surface of the base 314, which facilitates the attraction between the moving frame 301 and the housing 300. In addition, the first roller 320 can be pressed between the base 314 and the intermediate support 318, and the second roller 321 can be pressed between the moving frame 301 and the intermediate support 318, so that the base 314 and the intermediate support 318 can move relative to each other, and the intermediate support 318 and the moving frame 301 can move relative to each other, thereby realizing the decoupling anti-shake effect of the driving device 201 in the first direction and the second direction, and reducing the risk of crosstalk in the optical anti-shake process. The intermediate support 318 corresponds to the intermediate support 325 in the first embodiment.

[0257] In combination with FIG. 24 and FIG. 25, in some embodiments, in the thickness direction of the driving device 201, the distance between the second coil assembly 310 and the second magnetic assembly 309 on the first mounting surface is less than the distance between the second coil assembly 310 and the second magnetic assembly 309 on the second mounting surface; the moving frame 301 is a plate structure, and the second coil assembly 310 is located on the side of the moving frame 301 facing the first mounting surface. In this way, the second coil assembly 310 is biased towards the second magnetic assembly 309 on the first mounting surface in the thickness direction of the driving device 201, so that the second magnetic yoke 327 is attracted to the second magnet 328 on the first mounting surface of the base 314, which helps to ensure that the moving frame 301 and the housing 300 can be attracted to each other; in addition, the first roller 320 can be pressed between the base 314 and the intermediate support 318, and the second roller 321 can be pressed between the moving frame 301 and the intermediate support 318, so that the base 314 and the intermediate support 318 can move relative to each other, and the intermediate support 318 and the moving frame 301 can move relative to each other, thereby achieving decoupling and anti-shake effect of the driving device 201 in the first direction and the second direction, and reducing the risk of crosstalk occurring in the optical anti-shake process. The first roller 320 corresponds to the first roller 327 in the first embodiment; the second roller 321 corresponds to the second roller hole 328 in the first embodiment.

[0258] Referring to FIG. 25, in some embodiments, the first magnet 325 can be a multi-pole magnet, and the second magnet 328 can be a multi-pole magnet; when the first magnet 325 and the second magnet 328 are multi-pole magnets, the driving device 201 can provide a more uniform magnetic field or a stronger local magnetic field in a limited space, thereby achieving improved driving force. For example, the multi-pole magnet has a plurality of magnetic poles on each of the two opposite surfaces of the magnet; in the thickness direction of the driving device 201, each magnetic pole of one surface is magnetically opposite to each corresponding magnetic pole of the other surface. The second magnet 328 corresponds to the second magnet 322 in the first embodiment.

[0259] It should be noted that in some other possible embodiments, the first magnets 325 are single-pole magnets, and the second magnets 328 are single-pole magnets, which can meet different design requirements. A single-pole magnet has only one magnetic pole on each of the two opposite faces of the magnet. When the first magnets 325 are single-pole magnets, the number of the first magnets 325 in the first magnetic assembly 307 is multiple, for example, two, and the two first magnets 325 are arranged side by side, and the magnetic poles of the two first magnets 325 facing the same side are opposite. When the second magnets 328 are single-pole magnets, the number of the second magnets 328 in the second magnetic assembly 309 is multiple, for example, two, and the two second magnets 328 are arranged side by side, and the magnetic poles of the two second magnets 328 facing the same side are opposite. It can be understood that in one drive device 201, the type of the first magnets 325 and the type of the second magnets 328 can be the same or different, that is, both are multi-pole magnets, or both are single-pole magnets, or one is a multi-pole magnet and the other is a single-pole magnet, which can be selected according to actual needs.

[0260] FIG. 26 is a state diagram of the cooperation of the first coil assembly 308 and the second coil assembly 310 in the first form in the embodiment of the application; as shown in FIG. 26, the first magnetic yoke 323 is arranged at the hole center of the coil hole 324 of the first coil 322; the second magnetic yoke 327 is arranged at the hole center of the coil hole 324 of the second coil 326; in this way, the first magnetic yoke 323 and the first magnet 325 on the base 314 can be directly attracted to each other, and the second magnetic yoke 327 and the second magnet 328 on the base 314 are attracted to each other, so that the moving frame 301 can be adsorbed on the shell 300, but the moving frame 301 can move in the first direction when the first coil assembly 308 is powered, and the moving frame 301 can also move in the second direction when the second coil assembly 310 is powered. For example, the first magnetic yoke 323 is in a sheet structure, and the second magnetic yoke 327 is in a sheet structure, and the larger area of the first magnetic yoke 323 and the larger area of the second magnetic yoke 327, that is, the length and the width, are parallel to the first direction and the second direction, respectively, so that the first magnet 325 on the base 314 and the first magnetic yoke 323 can have a strong magnetic attraction force; the second magnet 328 on the base 314 and the second magnetic yoke 327 can also have a strong magnetic attraction force.

[0261] Figure 27 is a diagram showing the cooperation between the first coil assembly 308 and the second coil assembly 310 in the second form of the embodiment of the present application. As shown in Figure 27, the first coil 322 is provided with a plurality of first flux-concentrating yokes 323, at least two of which are spaced apart in the length direction of the first coil 322, which is parallel to the first direction. The second coil 326 is provided with a plurality of second flux-concentrating yokes 327, at least two of which are spaced apart in the length direction of the second coil 326, which is parallel to the second direction. The provision of the plurality of first flux-concentrating yokes 323 and the plurality of second flux-concentrating yokes 327 can also ensure that the intermediate support 318 is pressed between the moving frame 301 and the base 314. The moving frame 301 can move in the first direction when the first coil assembly 308 is energized, and the moving frame 301 can also move in the second direction when the second coil assembly 310 is energized. For example, the number of the first flux-concentrating yokes 323 is two, and the number of the second flux-concentrating yokes 327 is two. The first flux-concentrating yokes 323 are in the form of a sheet, and the second flux-concentrating yokes 327 are also in the form of a sheet. The larger faces of the first flux-concentrating yokes 323 and the larger faces of the second flux-concentrating yokes 327, i.e. the faces formed by the length and the width, are parallel to the thickness direction of the driving device 201. In this way, the first magnet 325 on the base 314 can have sufficient magnetic attraction with the first flux-concentrating yokes 323, and the second magnet 328 on the base 314 can also have sufficient magnetic attraction with the second flux-concentrating yokes 327.

[0262] Figure 28 is a diagram showing the cooperation of the first coil assembly 308 and the second coil assembly 310 in the third form of the embodiment of the application. As shown in Figure 28, the first coil 322 comprises an outer coil portion 334 and an inner coil portion 335 connected in series, the outer coil portion 334 of the first coil 322 is sleeved outside the inner coil portion 335 of the first coil 322, and a first magnetic yoke 323 is arranged between the outer coil portion 334 of the first coil 322 and the inner coil portion 335 of the first coil 322, and the first magnetic yoke 323 between the outer coil portion 334 of the first coil 322 and the inner coil portion 335 of the first coil 322 is annular. The second coil 326 comprises an outer coil portion 334 and an inner coil portion 335 connected in series, the outer coil portion 334 of the second coil 326 is sleeved outside the inner coil portion 335 of the second coil 326, and a second magnetic yoke 327 is arranged between the outer coil portion 334 of the second coil 326 and the inner coil portion 335 of the second coil 326, and the second magnetic yoke 327 between the outer coil portion 334 of the second coil 326 and the inner coil portion 335 of the second coil 326 is annular. The first magnetic yoke 323 and the second magnetic yoke 327 arranged in this way can also ensure that the middle support 318 is pressed between the moving frame 301 and the base 314, and the moving frame 301 can move in the first direction under the condition that the first coil assembly 308 is powered on, and the moving frame 301 can also move in the second direction under the condition that the second coil assembly 310 is powered on. For example, the first magnetic yoke 323 adopts a sheet structure to form an annular shape. From the center of the coil hole 324 of the first coil 322 to the outside, the order is the inner coil portion 335, the first magnetic yoke 323, and the outer coil portion 334, the first magnetic yoke 323 is sleeved outside the inner coil portion 335, and the outer coil portion 334 is sleeved outside the first magnetic yoke 323. Therefore, since the first magnetic yoke 323 is annular, the first magnet 325 on the base 314 and the first magnetic yoke 323 can have sufficient magnetic attraction. Similarly, the second magnetic yoke 327 adopts a sheet structure to form an annular shape. From the center of the coil hole 324 of the second coil 326 to the outside, the order is the inner coil portion 335, the second magnetic yoke 327, and the outer coil portion 334, the second magnetic yoke 327 is sleeved outside the inner coil portion 335, and the outer coil portion 334 is sleeved outside the second magnetic yoke 327. Therefore, since the second magnetic yoke 327 is annular, the second magnet 328 on the base 314 and the second magnetic yoke 327 can have sufficient magnetic attraction.

[0263] Figure 29 is a state diagram of the cooperation of the first coil assembly 308 and the second coil assembly 310 in the fourth form of the embodiment of the application. Referring to Figure 29, the first coil 322 includes two coil layers 336 connected in series, and the two coil layers 336 of the first coil 322 are stacked in the thickness direction of the driving device 201. A first magnetic yoke 323 is arranged between the two coil layers 336 of the first coil 322, and the first magnetic yoke 323 between the two coil layers 336 of the first coil 322 is annular. The second coil 326 includes two coil layers 336 connected in series, and the two coil layers 336 of the second coil 326 are stacked in the thickness direction of the driving device 201. A second magnetic yoke 327 is arranged between the two coil layers 336 of the second coil 326, and the second magnetic yoke 327 between the two coil layers 336 of the second coil 326 is annular. The first magnetic yoke 323 and the second magnetic yoke 327 arranged in this way can also ensure that the middle support 318 is pressed between the moving frame 301 and the base 314. The moving frame 301 can move in the first direction when the first coil assembly 308 is energized, and the moving frame 301 can also move in the second direction when the second coil assembly 310 is energized. For example, the first magnetic yoke 323 adopts a sheet structure to form an annular shape, and the larger area of the first magnetic yoke 323 is parallel to the first direction and the second direction, respectively. In this way, the first magnetic stone 325 on the base 314 can have sufficient magnetic attraction with the first magnetic yoke 323. Similarly, the second magnetic yoke 327 adopts a sheet structure to form an annular shape, and the larger area of the second magnetic yoke 327 is parallel to the first direction and the second direction, respectively. In this way, the second magnetic stone 328 on the base 314 can have sufficient magnetic attraction with the second magnetic yoke 327.

For example, the side of the moving frame 301 facing the base 314 can also have the first annular groove 342 and the second annular groove 343, the first annular groove 342 is located in the circumferential direction of the first winding column 339, and the second annular groove 343 is located in the circumferential direction of the second winding column 340, so as to facilitate the reduction of the thickness of the driving device 201. The first sensing element 332 corresponds to the first sensing element 324 in the first embodiment.

The intermediate support 318 cooperates with the first rod structure 344, the second rod structure 345 and the third rod structure 346, so that one side of the length direction of the intermediate support 318 is open, which is beneficial to avoid other components of the driving device 201 and reduce interference. For example, the side of the length direction of the intermediate support 318 is open and faces the first circuit board 330.

The material of the rib structure 319 can be metal, which can be aluminum alloy, copper, titanium, stainless steel, etc. For example, the number of the strip structures 352 embedded in the moving frame 301 is four, and the four strip structures 352 are connected end to end to form a closed quadrilateral structure, so that the overall strength of the moving frame 301 can be improved when the rib structure 319 is embedded in the moving frame 301. It should be noted that for the intermediate support 318, since it adopts a three-rod structure connection mode, the number of the strip structures 352 embedded in the corresponding intermediate support 318 is three, and the three strip structures 352 are connected, and the strip structures 352 are embedded in the first rod structure 344, the second rod structure 345 and the third rod structure 346, respectively. The rib structure 319 corresponds to the rib structure 338 in the first embodiment. The strip structure 352 corresponds to the strip structure 339 in the first embodiment.

[0272] Fig. 36 is a structural schematic view of a first positional relationship among the first driving assembly 304, the second driving assembly 305 and the hole structure 313 in the embodiments of the present application. Fig. 37 is a top view of Fig. 36. As shown in Figs. 36 and 37, in some embodiments, the moving frame 301 is provided with a mounting area 311 for mounting a device to be driven, and the mounting area 311 includes a mounting sub-area 312. The mounting sub-area 312 is used to facilitate the mounting of the device to be driven, and is conducive to ensuring the stability of the mounting of the device to be driven on the driving device 201, and is also conducive to meeting the requirements of the device to be driven, such as meeting the optical anti-shake function of the optical device. The mounting sub-area 312 includes the hole structure 313. The mounting area 311 corresponds to the mounting area 303 in the first embodiment. The mounting sub-area 313 corresponds to the mounting sub-area 308 in the first embodiment.

[0273] As shown in FIG. 36 and FIG. 37, the mounting area 311 has a mounting side 353, the first driving assembly 304 is located on the mounting side 353, and the second driving assembly 305 is located on the mounting side 353; the mounting side 353 includes a first mounting side 354 and a second mounting side 355, the direction from the first mounting side 354 to the second mounting side 355 is parallel to the length direction of the driving device 201; the first driving assembly 304 has a first projection in a first plane, the second driving assembly 305 has a second projection in the first plane, and the hole structure 313 has a third projection in the first plane, the first plane is parallel to the first direction, and the first plane is parallel to the second direction; the first projection in the first plane does not coincide with the third projection in the first plane, the second projection in the first plane does not coincide with the third projection in the first plane, a second plane is parallel to the length direction of the driving device 201, the second plane is perpendicular to the first plane, and the length direction of the driving device 201 is parallel to the first direction. In the embodiment of the present application, the first driving assembly 304 and the second driving assembly 305 responsible for movement in different directions are mounted on the mounting side 353, the direction from the first mounting side 354 to the second mounting side 355 is parallel to the length direction of the driving device 201, the first projection in the first plane does not coincide with the third projection in the first plane, and the second projection in the first plane does not coincide with the third projection in the first plane, so that the first driving assembly 304 and the second driving assembly 305 are distributed in the length direction of the driving device 201, thereby facilitating the reduction of the overall size of the driving device 201 in the width direction, so that the driving device 201 can meet the size limitation in the width direction, and still use the first driving assembly 304 and the second driving assembly 305 to meet the driving force required by the driving device 201 to drive the to-be-driven device (such as the lens 202 or the optical device of the image sensor). The mounting side 353 corresponds to the mounting side 304 in the first embodiment. The first driving assembly 304 corresponds to the first driving assembly 305 in the first embodiment; the second driving assembly 305 corresponds to the second driving assembly 306 in the first embodiment. The first mounting side 354 corresponds to the first mounting side 347 in the first embodiment; and the second mounting side 355 corresponds to the second mounting side 348 in the first embodiment.

[0274] For example, the first direction is parallel to the length direction of the driving device 201, and the second direction is parallel to the width direction of the driving device 201. Thus, the first driving assembly 304 drives the moving frame 301 to move along the length direction of the driving device 201, and the second driving assembly 305 drives the moving frame 301 to move along the width direction of the driving device 201. The first orthographic projection in the second plane and the third orthographic projection in the second plane can be separated from each other or have only one common point. The second orthographic projection in the second plane and the third orthographic projection in the second plane can be separated from each other or have only one common point. The number of the first driving assembly 304 is one or more, for example, 1, 2 or 3, etc. The number of the second driving assembly 305 is one or more, for example, 1, 2 or 3, etc.

[0275] It should be noted that in some other possible embodiments, the second direction can be parallel to the length direction of the driving device 201, and the first direction can be parallel to the width direction of the driving device 201. In addition, it should be noted that in the embodiments of the present application, the first driving assembly 304 is located on the mounting side 353, and the second driving assembly 305 is located on the mounting side 353. The connection relationship between the first driving assembly 304 and the second driving assembly 305 and the moving frame 301 is not limited, but the spatial relative position relationship of the first driving assembly 304 and the second driving assembly 305 is limited with reference to the first mounting side 354 and the second mounting side 355 of the moving frame 301.

[0276] In some embodiments, the length of the driving device 201 is greater than the width of the driving device 201, which is conducive to achieving that the driving device 201 can be small in width, and the first driving assembly 304 and the second driving assembly 305 can be arranged in the length direction to have appropriate driving force to meet the needs of driving the to-be-driven device, such as the driving force required for long-stroke optical anti-shake of a lens 202 with a large aperture or a large mass. For example, the driving device 201 is in the shape of a cuboid, the base 314 is in the shape of a cuboid, and the moving frame 301 is in the shape of a cuboid. The length of the base 314 is greater than the width of the base 314, and the length of the moving frame 301 is greater than the width of the moving frame 301. The length direction of the base 314 is parallel to the length direction of the moving frame 301, the width direction of the base 314 is parallel to the width direction of the moving frame 301, the thickness direction of the base 314 is parallel to the thickness direction of the moving frame 301, the first direction is parallel to the length direction of the moving frame 301, and the second direction is parallel to the width direction of the moving frame 301. After the camera module 200 is installed in the shell 101, the length direction of the camera module 200 is parallel to the width direction of the electronic device, so that the space occupied by the camera module in the length direction of the electronic device can be reduced. It can be understood that, according to the installation requirements, the length direction of the camera module 200 can also be parallel to the length direction of the electronic device to reduce the space occupied by the camera module 200 in the width direction of the electronic device.

[0277] It should be noted that, in some other possible embodiments, the length of the driving device 201 can also be equal to the width of the driving device 201, which, in combination with the at least two first magnetic assemblies 307 and the at least two second magnetic assemblies 309, can meet the driving force required for long-stroke optical anti-shake of a to-be-driven device (such as a lens 202 with a large aperture and / or a large mass).

[0278] In combination with FIG. 36 and FIG. 37, the hole structure 313 is located between the first mounting side 354 and the second mounting side 355 in the length direction of the driving device 201. The hole structure 313 is opposite to the first mounting side 354 and the second mounting side 355 in the length direction of the driving device 201. For example, the hole structure 313 is a circular hole, and the two ends of the diameter of the circular hole parallel to the length direction of the driving device 201 are respectively referred to as the first end point E and the second end point F; two sides are arranged in the length direction of the moving frame 301, and the opposite two sides are respectively referred to as the first side edge 356 and the second side edge 357; in the length direction of the driving device 201, the first end point E and the first side edge 356 are located on one side of the hole center O of the circular hole, and the second end point F and the second side edge 357 are located on the other side of the hole center O of the circular hole; the straight line passing through the first end point E and parallel to the width direction of the driving device 201 is the first straight line L1, and the straight line passing through the second end point F and parallel to the second direction is the second straight line L2; the region extending from the first straight line L1 to the direction of the first side edge 356 is the first mounting side 354 of the mounting area 311, and the region extending from the second straight line L2 to the direction of the second side edge 357 is the second mounting side 355 of the mounting area 311. The first mounting side 354 and the second mounting side 355 are oppositely arranged, and the regions of the mounting sub-area 312 on the opposite sides in the length direction of the driving device 201 are respectively the first mounting side 354 and the second mounting side 355. In this way, the first driving assembly 304 and the second driving assembly 305 are arranged on the mounting side 353, so as to reduce the space occupied by the first driving assembly 304 and the second driving assembly 305 in the width direction of the driving device 201. In at least one embodiment, the driving assembly is arranged on at least one of the opposite sides of the hole structure 313 in the first direction, and the driving assembly is not arranged on the opposite sides of the hole structure 313 in the second direction, that is, the driving assembly is arranged on the opposite sides of the lens 202 in the length direction of the driving device 201, and the driving assembly is not arranged on the opposite sides of the lens 202 in the width direction. In this way, the driving assembly is asymmetrically distributed in the driving device 201. Compared with other embodiments in which the driving assembly is arranged in four directions of the optical device, the embodiment is beneficial to reduce the size of the driving device 201 in the width direction, so that the driving device 201 can adapt to smaller asymmetric space size in the electronic equipment, and the driving device 201 can drive the lens 202 with larger aperture and larger mass to have better optical performance. The hole structure 313 corresponds to the hole structure 313 in the first embodiment. The first side edge 356 corresponds to the first side edge 309 in the first embodiment. The second side edge 357 corresponds to the second side edge 310 in the first embodiment.

[0279] It should be noted that when the hole structure 313 is a rectangular hole, the two opposite sides of the rectangular hole in the length direction of the driving device 201 are respectively the first mounting side 354 and the second mounting side 355 of the mounting side 353. It can be understood that although in the embodiment of the present application, the first driving assembly 304 or the second driving assembly 305 is not mounted on the two opposite sides of the hole structure 313 in the width direction of the driving device 201, so as to reduce the overall size of the driving device 201 in the second direction and meet the requirement of driving force when the lens 202 with a larger aperture or a larger mass performs long-stroke optical anti-shake. However, in some other possible application scenarios, the first driving assembly 304 or the second driving assembly 305 can also be mounted on the two opposite sides of the hole structure 313 in the width direction of the driving device 201.

[0280] In some embodiments, as shown in FIGS. 36 and 37, the first driving assembly 304 can be completely located on the mounting side 353, and the second driving assembly 305 can be completely located on the mounting side 353. In this way, the size of the driving device 201 in the second direction can be reduced, so that the driving device 201 can be adapted to smaller asymmetric space sizes in electronic devices, and the driving device 201 can drive the lens 202 with a larger aperture and a larger mass to perform optical anti-shake with better optical performance.

[0281] Referring to FIG. 37, the first driving assembly 304 is located at the first mounting side 354, and the second driving assembly 305 is located at the second mounting side 355. For example, the driving device 201 can include a first driving assembly 304 and a second driving assembly 305, as shown in FIG. 37, the first driving assembly 304, the hole structure 313 and the second driving assembly 305 are arranged in sequence in the length direction of the driving device 201, so that the first driving assembly 304 and the second driving assembly 305 are distributed on the mounting side 353, which can meet the installation position of the driving device 201 in the electronic equipment and the space requirement in a single direction in the electronic equipment, etc. The length side of the driving device 201 is parallel to the length direction of the driving device 201, and the width side of the driving device 201 is parallel to the width direction of the driving device 201; in the length direction of the driving device 201, the distance D2 between the center O of the hole structure 313 and one width side of the driving device 201 is greater than the distance D1 between the center O of the hole structure 313 and the other width side of the driving device 201, so that the center O of the hole structure 313 does not coincide with the center of the moving frame 301, and the hole structure 313 is designed eccentrically relative to the center of the moving frame 301, so as to meet the installation position of the driving device 201 in the electronic equipment and the space requirement in a single direction in the electronic equipment, so that the driving device 201 can adapt to different installation occasions, and the asymmetric distribution of the driving assemblies in the driving device 201 is realized, which is beneficial to the miniaturization of the driving device 201 and improves the space utilization of the camera module 200; because the first driving assembly 304 and the second driving assembly 305 are placed in different ways, in FIG. 37, the area occupied by the first mounting side 354 where the first driving assembly 304 is located on the moving frame 301 can be smaller than the area occupied by the second mounting side 355 where the second driving assembly 305 is located.

[0282] FIG. 38 is a structural schematic view of a second positional relationship among the first driving assembly 304, the second driving assembly 305 and the hole structure 313 in the embodiments of the present application; as shown in FIG. 38, in some other embodiments, the first driving assembly 304 and the second driving assembly 305 are both located on the second mounting side 355. For example, the second mounting side 355 is provided with one first driving assembly 304 and one second driving assembly 305, and the first mounting side 354 is not provided with the first driving assembly 304 and the second driving assembly 305, and the hole structure 313, the first driving assembly 304 and the second driving assembly 305 are sequentially arranged in the length direction of the driving device 201. For example, in the length direction of the driving device 201, the distance D2 between the center O of the hole structure 313 and one width side of the driving device 201 is greater than the distance D1 between the center O of the hole structure 313 and the other width side of the driving device 201, so that the center O of the hole structure 313 does not coincide with the center of the moving frame 301, and the hole structure 313 is designed to be eccentric relative to the center of the moving frame 301, so as to meet the installation position of the driving device 201 in the electronic device and the space requirement in a single direction in the electronic device, so that the driving device 201 can adapt to different installation occasions, and the asymmetric distribution of the driving assemblies in the driving device 201 is combined, which is beneficial to the miniaturization of the driving device 201 and improves the space utilization of the camera module 200. It should be noted that in some other possible embodiments, one of the first mounting side 354 and the second mounting side 355 can be provided with one or more first driving assemblies 304 and one or more second driving assemblies 305, for example, 2-3 first driving assemblies 304 and 2-3 second driving assemblies 305, and the other one can not be provided with the first driving assembly 304 and the second driving assembly 305.

[0283] FIG. 39 is a structural schematic view of a third positional relationship among the first driving assembly 304, the second driving assembly 305 and the hole structure 313 according to some embodiments of the present application. As shown in FIG. 39, in some embodiments, the first driving assembly 304 and the second driving assembly 305 are both located on the second mounting side 355. For example, the second mounting side 355 is provided with one first driving assembly 304 and one second driving assembly 305, and the first mounting side 354 is not provided with the first driving assembly 304 and the second driving assembly 305. The hole structure 313, the second driving assembly 305 and the first driving assembly 304 are arranged in sequence in the length direction of the driving device 201. For example, in the length direction of the driving device 201, the distance D2 between the center O of the hole structure 313 and one width side of the driving device 201 is greater than the distance D1 between the center O of the hole structure 313 and the other width side of the driving device 201. In this way, the center O of the hole structure 313 is not coincident with the center of the moving frame 301, and the hole structure 313 is designed to be eccentric relative to the center of the moving frame 301. Thus, the installation position of the driving device 201 in the electronic device and the space requirement of the driving device 201 in a single direction in the electronic device can be satisfied, and the driving device 201 can be adapted to different installation occasions. In combination with the asymmetric distribution of the driving assemblies in the driving device 201, the size of the driving device 201 can be miniaturized, and the space utilization of the camera module 200 can be improved. It should be noted that in some other possible embodiments, one of the first mounting side 354 and the second mounting side 355 can be provided with one or more first driving assemblies 304 and one or more second driving assemblies 305, and the other one can be provided with one first driving assembly 304 or one second driving assembly 305.

[0284] Figure 40 is a structural schematic diagram of a fourth positional relationship among the first driving assembly 304, the second driving assembly 305 and the hole structure 313 according to an embodiment of the present application. As shown in Figure 40, in some embodiments, the whole formed by the first driving assembly 304 and the second driving assembly 305 located at the first mounting side 354 is arranged in a center symmetry with the whole formed by the first driving assembly 304 and the second driving assembly 305 located at the second mounting side 355. In this way, the first driving assembly 304 and the second driving assembly 305 are distributed on the mounting side 353, which can meet the balance of the movement of the moving frame 301 in different directions, the balance of the overall mass of the driving device 201, the requirement of the driving force of the driving device 201 in different directions, the installation position of the driving device 201 in the electronic device and the space requirement of the driving device 201 in a single direction in the electronic device, etc. For example, as shown in Figure 40, the first driving assembly 304 and the second driving assembly 305 located at the first mounting side 354 are arranged in the width direction of the driving device 201, and the first driving assembly 304 and the second driving assembly 305 located at the second mounting side 355 are arranged in the width direction of the driving device 201. The line between the first driving assembly 304 located at the first mounting side 354 and the first driving assembly 304 located at the second mounting side 355 intersects with the line between the second driving assembly 305 located at the first mounting side 354 and the second driving assembly 305 located at the second mounting side 355, which realizes the diagonal arrangement between the first driving assembly 304 located at the first mounting side 354 and the first driving assembly 304 located at the second mounting side 355 and the diagonal arrangement between the second driving assembly 305 located at the first mounting side 354 and the second driving assembly 305 located at the second mounting side 355, thereby ensuring the stability of the movement of the moving frame 301.

In this way, the first driving assembly 304 and the second driving assembly 305 are distributed on the mounting side 353, which can meet different requirements, such as the balance of the movement of the moving frame 301 in different directions, the balance of the overall mass of the driving device 201, the requirement of the driving force of the driving device 201 in different directions, the installation position of the driving device 201 in the electronic device and the space requirement of the driving device 201 in a single direction in the electronic device, etc.

[0286] Fig. 42 is a structural diagram of another driving device 201 according to an embodiment of the present application. As shown in Fig. 42, in another possible implementation, two mounting surfaces 306 are respectively fixed with first coil assemblies 308, and the moving frame 301 is fixed with a first magnetic assembly 307. Two mounting surfaces 306 are respectively fixed with second coil assemblies 310, and the moving frame 301 is fixed with a second magnetic assembly 309. In this way, the two first coil assemblies 308 respectively cut the magnetic induction lines, and the two second coil assemblies 310 respectively cut the magnetic induction lines, thereby facilitating the driving device 201 to meet the driving force required for driving the to-be-driven device (such as the lens 202 or the optical device of the image sensor). For example, the first magnetic assembly 307 is located between the two first coil assemblies 308 cooperating with the first magnetic assembly 307, and the second magnetic assembly 309 is located between the two second coil assemblies 310 cooperating with the second magnetic assembly 309. The first coil assembly 308 corresponds to the first coil assembly 312 in the first embodiment, and the second coil assembly 310 corresponds to the second coil assembly 314 in the first embodiment.
