The second elastic member 620 may be a suspension wire having both elasticity and rigidity so as to support the first bracket 300 such that the first bracket 300 is floated with respect to the second bracket 400.

Further, the number of the first elastic members 610 may be plural, and a plurality of the first elastic members 610 are distributed along the circumference of the second stent 400. In this scheme, the number of the first elastic members 610 is plural, so that the supporting force provided for the second bracket 400 is balanced, and the supporting function of the second bracket 400 is better.

In another alternative embodiment, the first elastic element 610, the second elastic element 620 and the third elastic element 630 are electrically connected in sequence, the second elastic element 620 is electrically connected to the second coil group 530, and the third elastic element 630 is electrically connected to the first coil group 520.

Alternatively, the first elastic member 610 may be connected to a circuit structure of the camera module to supply power to the first coil set 520, the second coil set 530, and the third coil set 540.

In another alternative embodiment, each of the first elastic members 610 may be electrically connected to one electrode of the first coil group 520 and the second coil group 530. At this time, each of the first elastic members 610 is electrically connected to one electrode, so that a cross-current phenomenon between the electrodes in the first coil group 520 and the second coil group 530 can be realized.

In another alternative embodiment, the first coil set 520 may include at least two first sub-coils disposed opposite to each other, and the magnet set 510 may include at least two magnets disposed opposite to each other, and each magnet may be disposed opposite to one first sub-coil. At this time, the directions of the ampere forces generated by the at least two oppositely arranged first sub-coils are the same.

In this scheme, two at least first sub-coils can be located the both sides that carry on the back of the body of camera lens subassembly to make the lens subassembly atress balanced, thereby prevent that the slope from appearing in the lens subassembly, and then make the lens subassembly remove more steadily.

In another alternative embodiment, the second coil group 530 may include at least four second sub-coils disposed around the first carrier 300, and the magnet group 510 may include at least four magnets disposed around the first carrier 300, each of the second sub-coils being disposed opposite to one of the magnets. With one pair of opposing second sub-coils energized, the first carrier 300 is driven to move along a first axis (an axis shown as the X-axis in fig. 6). With the other pair of opposing second sub-coils energized, the first carrier 300 is driven to move along the second axis (the axis shown as the Y-axis in fig. 6). The first plane is a plane in which the first axis and the second axis are located, and the first axis and the second axis intersect.

In addition, the forces of the two opposing second sub-coils are more even.

The first support 300 in the above-mentioned scheme is not limited to move along the first axis and the second axis, and by the mutual matching of the two adjacent second sub-coils, the movement of the first support 300 on the first plane can be realized, so that the movement range of the lens assembly is increased.

In another alternative embodiment, the third coil set 540 may include at least four third sub-coils surrounding the second carrier 400, each third sub-coil being disposed opposite one of the magnets, and the second carrier 400 is driven to rotate along the first axis when one pair of the opposite third sub-coils is energized.

Wherein the two third sub-coils driving the second carrier 400 to rotate along the first axis are distributed along the second axis. Two third sub-coils driving the second carrier 400 to rotate along the second axis are distributed along the first axis.

Alternatively, since the moving directions of the two first sub-coil driving lens assemblies are the same, the two first sub-coils may share the same set of electrodes, and the first coil set 520 requires two electrodes, a positive electrode and a negative electrode. The second coil group 530 has four second sub-coils, and since the two second sub-coils disposed opposite to each other drive the first yoke 300 to move in the same direction, the two first sub-coils disposed opposite to each other share the same group of electrodes. At this time, two pairs of electrodes, i.e., four electrodes, are required for the four second sub-coils, so that six first elastic members 610 are required to meet the power supply requirements of the first coil group 520 and the second coil group 530.

In the present application, in order to balance the force applied to the second bracket 400, eight first elastic members 610 are provided, and two first elastic members 610 form a group and are supported at one corner of the second bracket 400, at this time, six first elastic members 610 are used for both supporting and supplying power, and the remaining two are used for only supporting and not supplying power. When the camera module needs to increase its anti-shake direction, the remaining two first elastic members 610 may be used to electrically connect with the added coils. Since the third coil set 540 is directly disposed on the circuit board, power does not need to be supplied through the first elastic member 610, and the first elastic member 610 is only used for supplying power to the first coil set 520 and the second coil set 530.

In the above embodiment, the at least four second sub-coils and the at least four third sub-coils may be located on the same side of the second support 400, so that the at least four second sub-coils and the at least four third sub-coils are distributed in a staggered manner to form a ring structure, and interference easily occurs between the second coil group 530 and the third coil group 540.

Based on this, in another alternative embodiment, at least four second sub-coils may be located on the same plane and on the surface of the second bracket 400 on the side facing the first bracket 300. At this time, the second coil group 530 is located between the first bracket 300 and the second bracket 400, that is, below the magnet group 510, and the third coil group 540 is disposed around the outside of the second coil group 530.

In this scheme, the mounting position of the second coil assembly 530 is not easy to occupy the mounting position of the third coil assembly 540, so that the second coil assembly 530 and the third coil assembly 540 are not easy to interfere, thereby improving the assembling performance of the camera module.

Alternatively, the second coil assembly 530 may be disposed on a surface of a flat plate, and a surface of the flat plate facing away from the second coil assembly 530 is attached to the second bracket 400.

In another alternative embodiment, the camera module disclosed in the present application may further include a circuit board 700, and the circuit board 700 is located in the inner cavity and disposed in the module housing 100. The third coil set 540 may be disposed on the circuit board 700 and electrically connected to the circuit board 700. At this time, the third coil assembly 540 is close to the circuit board 700, and thus the third coil assembly 540 is directly disposed on the circuit board 700, so that a fixing member of the third coil assembly 540 does not need to be disposed, and the structure of the camera module is simpler and more compact.

Alternatively, the circuit board 700 may have a ring-shaped structure so as to be disposed around the second bracket 400; or the circuit board 700 may be multiple, each third sub-coil corresponds to one circuit board 700, and each circuit board 700 is attached to the corresponding inner side wall of the module housing 100.

In the above embodiment, the first coil set 520 and the second coil set 530 are both powered by the circuit board 700, that is, the first elastic member 610 is electrically connected to the circuit board. At this time, it is not necessary to provide an additional circuit structure for supplying power to the first coil assembly 520 and the second coil assembly 530, so that the structure of the camera module is simpler.

The detecting element 800 may be a hall chip, and of course, may also be other types of chips, which is not limited herein.

In a specific operation process, the circuit board 700 may further be provided with a control chip, the control chip is electrically connected to the circuit board 700, and the control chip may control the current of the coil assembly according to a detection signal of the gyroscope or the detection element 800, so as to generate magnetic fields with different strengths in different regions, and further generate appropriate motion for counteracting the influence caused by external shaking.

When the gyroscope inside the electronic equipment or the camera module detects the inclination of the camera module, the gyroscope transmits data such as the inclination angle of the camera module to the control chip, the control chip inputs corresponding angle compensation amount, and the control chip outputs corresponding current, so that the corresponding coil group is controlled to be electrified, and then the lens assembly is driven to move.

When the lens assembly moves, the detection element 800 can detect the deflection angle of the lens assembly, and a detection signal can be fed back to the control chip, so that the deflection angle of the lens assembly is corrected.

Specifically, the number of the sensing elements 800 may be plural, and the plural sensing elements 800 are respectively installed at the center positions of the corresponding third sub-coils.
