The following describes the camera module provided in the embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 1 to 13, an embodiment of the present application discloses a camera module, which is applied to an electronic device. The disclosed camera module includes a module housing 100, a lens assembly, and a drive mechanism.

The module housing 100 provides an installation foundation for the lens assembly, the driving mechanism, and other components of the camera module. The module housing 100 defines an accommodating space, and the lens assembly is movably disposed in the accommodating space, that is, the lens assembly can move in the accommodating space.

The driving mechanism includes a magnet assembly and a coil assembly, one of the magnet assembly and the coil assembly is disposed on the module housing 100, and the other is disposed on the lens assembly.

The magnet group includes a first magnet 311, a second magnet 312, a third magnet 313, a fourth magnet 314, a fifth magnet 315, a sixth magnet 316, a seventh magnet 317, and an eighth magnet 318 surrounding the lens assembly; the coil assembly includes a first coil 321, a second coil 322, a third coil 323, a fourth coil 324, a fifth coil 325, a sixth coil 326, a seventh coil 327, and an eighth coil 328 surrounding the lens assembly.

The first magnet 311 is arranged opposite to the first coil 321, the second magnet 312 is arranged opposite to the second coil 322, the third magnet 313 is arranged opposite to the third coil 323, the fourth magnet 314 is arranged opposite to the fourth coil 324, the fifth coil 325 is arranged opposite to the fifth magnet 315, the sixth magnet 316 is arranged opposite to the sixth coil 326, the seventh coil 327 is arranged opposite to the seventh magnet 317, and the eighth coil 328 is arranged opposite to the eighth magnet 318. Since the first magnet 311 is aligned with the first coil 321, the first coil 321 is located in the magnetic field generated by the first magnet 311, and the first coil 321 is matched with the first magnet 311. The other coils are correspondingly located in the magnetic field of the corresponding magnets, and are not described in detail herein.

Specifically, the magnetic induction line of the first magnet 311 needs to pass through the first coil 321, and the arrangement direction of the two magnetic poles in the first magnet 311 is the same as the direction of the current in the first coil 321, and of course, other coils and other magnets are arranged in the same manner as the first magnet 311 and the first coil 321, which is not limited herein.

With the coil assembly energized, the lens assembly is driven in motion. At this time, when the coil group is energized, only one of the coils may be energized, several of the coils may be energized, or all of the coils may be energized.

In the embodiment disclosed by the application, under the condition that the coil group is electrified, the electrified coil group can generate ampere force in a magnetic field generated by the magnet group, and the ampere force can drive the lens assembly to move. Coil assembly and magnet group can drive the opposite direction motion of camera lens subassembly along the shake of camera module to can compensate the shake amount of camera module, and then can realize the anti-shake function of camera module, with the shooting quality that improves the camera module.

In addition, when the direction of the current introduced into the coil group is changed, the direction of the ampere force is changed, so that the lens assembly is flexible to reverse, and the anti-shaking effect is better.

In addition, every coil corresponds a magnet, and consequently coil assembly and magnet group can produce the ampere force of a plurality of directions to drive camera subassembly and move along a plurality of directions, and then improved the motion range of lens subassembly, further improved the anti-shake performance of camera module.

The coil assembly and the magnet assembly can drive the lens assembly to move in multiple directions, and a specific driving manner is provided herein, but other manners may also be adopted, and the present disclosure is not limited thereto. Specifically, as shown in fig. 4 and 5, when the first coil 321 and the fifth coil 325 are energized, the lens assembly can be driven to move along the first axis by the ampere force generated by the first coil 321 and the fifth coil 325, so that the first coil 321 and the fifth coil 325 need to generate the ampere force in the same direction to move the lens assembly toward the same direction. The first coil 321 and the fifth coil 325 are thus distributed on the first axis, i.e. the first coil 321 and the fifth coil 325 are also arranged opposite to each other. The first coil 321 and the fifth coil 325 are disposed to face each other, and thus the corresponding first magnet 311 and the corresponding fifth magnet 315 are also disposed to face each other.

As shown in fig. 4, the ampere force generated by the first coil 321 and the fifth coil 325 drives the lens assembly to move in the positive direction of the first axis. As shown in fig. 5, when the first coil 321 and the fifth coil 325 are applied with the opposite current as in fig. 4, the ampere force generated by the first coil 321 and the fifth coil 325 drives the lens assembly to move along the reverse direction of the first axis, and the positive direction and the negative direction face the opposite directions.

As shown in fig. 10 and 11, when the second coil 322 and the sixth coil 326 are energized, the lens assembly is driven to rotate along the second axis by the ampere force generated by the second coil 322 and the sixth coil 326, so that the second coil 322 and the sixth coil 326 need to generate the ampere force in the same direction to rotate the lens assembly in the same direction. The second coil 322 and the sixth coil 326 are thus distributed on the second axis, i.e. the second coil 322 and the sixth coil 326 are also arranged opposite to each other. The second coil 322 and the sixth coil 326 are disposed in facing relation, and therefore their respective second magnet 312 and sixth magnet 316 are also disposed in facing relation.

As shown in fig. 10, the ampere force generated by second coil 322 and sixth coil 326 drives the lens assembly in a positive direction about the second axis. As shown in fig. 11, when the currents of the second coil 322 and the sixth coil 326 are opposite to those of fig. 10, the ampere force generated by the second coil 322 and the sixth coil 326 drives the lens assembly to rotate around the negative direction of the second axis. Alternatively, the positive direction of the second axis may be clockwise and the negative direction of the second axis may be counter-clockwise.

As shown in fig. 6 and 7, with the third coil 323 and the seventh coil 327 energized, the ampere force generated by the third coil 323 and the seventh coil 327 may drive the lens assembly to move along the third axis. Therefore, the third coil 323 and the seventh coil 327 need to generate an ampere force in the same direction to move the lens assembly toward the same direction. The third coil 323 and the seventh coil 327 are thus distributed in the direction of the third axis, i.e. the third coil 323 and the seventh coil 327 are also arranged directly opposite one another. The third coil 323 and the seventh coil 327 are disposed to face each other, and therefore the corresponding third magnet 313 and seventh magnet 317 are also disposed to face each other.

As shown in FIG. 6, the ampere force generated by third coil 323 and seventh coil 327 drives the lens assembly in the positive direction along the third axis. As shown in fig. 7, when the third coil 323 and the seventh coil 327 are energized with an opposite current as in fig. 6, the ampere force generated by the third coil 323 and the seventh coil 327 drives the lens assembly to move in the opposite direction of the third axis.

With the fourth and

eighth coils

324, 328 energized, the ampere force generated by the fourth and

eighth coils

324, 328 may drive the lens assembly to rotate along the fourth axis, as shown in fig. 12 and 13. The fourth coil 324 and the eighth coil 328 need to generate an ampere force in the same direction to rotate the lens assembly in the same direction. The fourth coil 324 and the eighth coil 328 are therefore distributed over the fourth axis, i.e. the fourth coil 324 and the eighth coil 328 are also arranged opposite one another. The fourth coil 324 and the eighth coil 328 are disposed in facing relation, and therefore their respective fourth magnet 314 and eighth magnet 318 are also disposed in facing relation.

As shown in fig. 12, the ampere force generated by the fourth coil 324 and the eighth coil 328 drives the lens assembly in a positive direction about the fourth axis. When the fourth coil 324 and the eighth coil 328 are energized with opposite currents as in fig. 12, as shown in fig. 13, the ampere force generated by the fourth coil 324 and the eighth coil 328 drives the lens assembly to rotate in the negative direction about the fourth axis. Alternatively, the positive direction of the fourth axis may be clockwise and the negative direction of the fourth axis may be counter-clockwise.

In the above description, the first coil 321 and the fifth coil 325 are opposed to each other, the third coil 323 and the seventh coil 327 are opposed to each other, and when the first coil 321, the third coil 323, the fifth coil 325 and the seventh coil 327 are energized, the ampere force generated by the first coil 321, the third coil 323, the fifth coil 325 and the seventh coil 327 drives the lens assembly to rotate about the optical axis direction thereof. At this time, the directions of the ampere forces generated by the first coil 321 and the fifth coil 325 are opposite, the directions of the ampere forces generated by the third coil 323 and the seventh coil 327 are opposite, and the directions of the ampere forces generated by the first coil 321, the third coil 323, the fifth coil 325 and the seventh coil 327 are all tangential to the lens assembly, so that the lens assembly is driven to rotate around the optical axis direction thereof.

As shown in fig. 8, the ampere force generated by the first coil 321, the third coil 323, the fifth coil 325, and the seventh coil 327 drives the lens assembly to rotate about the positive direction of the optical axis thereof. As shown in fig. 9, the ampere force generated by the first, third, fifth and

seventh coils

321, 323, 325 and 327 drives the lens assembly in the negative direction about its optical axis.

The optical axis is intersected with a first plane, and the first plane is a plane where the first axis, the second axis, the third axis and the fourth axis are located. Alternatively, the first and second axes may be parallel, or the first and second axes intersect. The third axis and the fourth axis may be parallel, or the third axis and the fourth axis may intersect, without limitation.

In this scheme, first coil 321 and fifth coil 325 can drive the lens assembly to move along the first axis, second coil 322 and sixth coil 326 can drive the lens assembly to rotate along the second axis, third coil 323 and seventh coil 327 can drive the lens assembly to move along the third axis, fourth coil 324 and eighth coil 328 can drive the lens assembly to rotate along the fourth axis, first coil 321, third coil 323, fifth coil 325 and seventh coil 327 can drive the lens assembly to rotate along its optical axis direction, therefore, different combinations of coil group and magnet group can realize five-axis anti-shake of camera module, and then increase the shake adjusting range of lens assembly, further improve the anti-shake function of camera module, further improve the shooting quality of camera module.

In addition, the movement on the first axis, the second axis, the third axis and the fourth axis is driven by two pairs of coils and two pairs of magnets, so that the stress of the lens assembly is relatively balanced, and the driving precision of the lens assembly is improved.

In addition, because the sensitization chip 500 of actual camera module is the cuboid usually, when the camera module takes place the shake, the transmission direction of the light of camera module can take place the skew, therefore the camera lens subassembly rotates along its optical axis and can make the transmission direction of the light of camera module be difficult to take place the slope, has further improved the shooting quality of camera module.

In another alternative embodiment, the first axis, the second axis, the third axis and the fourth axis intersect two by two. In this scheme, the directions of the first axis, the second axis, the third axis and the fourth axis are all inconsistent. This scheme can further increase the angle that the camera module anti-shake, further improves the shooting performance of camera module.

Alternatively, the included angle between two adjacent axes may be 30 °, 45 ° or 60 °, and of course, other angles are also possible, which is not limited herein.

Further, the first axis and the third axis may be perpendicular, and the second axis and the fourth axis may be perpendicular. At this moment, the movement range of the lens assembly is further increased, and the anti-shake angle of the camera module is further increased.

One of the fifth coil 325 and the fifth magnet 315 is disposed at the fifth side. One of the sixth coil 326 and the sixth magnet 316 is disposed on the sixth side surface. One of the seventh coil 327 and the seventh magnet 317 is disposed at the seventh side surface. One of the eighth coil 328 and the eighth magnet 318 is disposed at the eighth side.

The direction of the magnetic induction line of one of the first magnets 311 is opposite to the direction of the magnetic induction line of the other first magnet 311.

The direction of the lines of magnetic induction of one of the second magnets 312 is opposite to the direction of the lines of magnetic induction of the other second magnet 312.
