Wherein, the first bracket 300 has a first side and a second side opposite to each other, the first anti-shake assembly 400 is disposed on the first side, and the second anti-shake assembly 500 is disposed on the second side. It can be understood that the first anti-shake assembly 400 and the second anti-shake assembly 500 are disposed on the same bracket and located on opposite sides of the first bracket 300. Compared with the related art in which the first anti-shake assembly 400 and the second anti-shake assembly 500 are respectively disposed on different supports, one support can be omitted, and the structure of the photographing device 20 can be simplified.

In addition, long-term research by the inventor finds that the elastic sheet type driving motor of some mobile phones usually uses the elastic sheet structure and the suspension ring line structure to realize the displacement of the driving motor in the horizontal direction and the vertical direction so as to drive the displacement of the lens in the horizontal direction and the vertical direction, but the problem of fracture of the elastic sheet structure and/or the suspension ring line is easy to occur in the process of realizing the displacement in the horizontal direction; the ball formula actuating motor of some cell-phones adopts a plurality of balls usually to realize the displacement of the horizontal direction of actuating motor and vertical direction in order to drive the horizontal direction of camera lens and vertical direction's displacement, however in the displacement process who realizes vertical direction, thereby a plurality of balls can strike each other and make a plurality of balls pit appear easily and lead to rolling problem not smooth and easy.

The first carrier 411 may be a regular shape, for example, the first carrier 411 may be a rectangular frame-structured first carrier 411. Of course, the first carrier 411 may also be a rounded rectangle or an irregular shape.

The second carrier 412 may be disposed in the through hole of the first carrier 411 and may move within the through hole. The lens 100 can be disposed on the second carrier 412, and when the second carrier 412 moves, the lens 100 can be driven to move. For example, the second supporting member 412 may also be a rectangular frame structure, the second supporting member 412 may be provided with a through hole, and the lens 100 may be inserted into the through hole and fixed to a hole wall of the through hole.

The guide 413 is stacked on a portion of the first carrier 411 in a direction parallel to the optical axis of the lens 100, such that a portion of the first carrier 411 is exposed outside the guide 413. For example, the guide 413 may include a first side and a second side connected to each other, which may have a substantially "L" shaped configuration. Compared with the guide piece 413 with a rectangular structure in the related art, the guide piece 413 of the embodiment of the present application can reduce the volume of the guide piece 413, thereby reducing the space occupation of the guide piece 413 on the first anti-shake assembly 400, and facilitating the miniaturization of the first anti-shake assembly 400.

As shown in fig. 4, the first anti-shake assembly 400 may further include a magnetic assembly 440, and the magnetic assembly 440 may be a permanent magnet or an electromagnet, which may generate a magnetic field. Wherein the magnetic assembly 440 may be disposed on the carrier 410, and the magnetic assembly 440 may include a plurality of magnetic members, each of which may include two magnets of opposite magnetic polarities.

The first driving module 420 is located in the magnetic field generated by the magnetic element 440, and the first driving module 420 can drive the carrier 410 to move along the direction parallel to the optical axis of the lens 100 under the action of the magnetic element 440. For example, the first driving module 420 may further include a first conductive member 422, the first conductive member 422 is disposed opposite to the magnetic assembly 440 in a direction perpendicular to the optical axis of the lens 100, based on fleming's left-hand rule, the first conductive member 422 may generate a magnetic field after being energized, the magnetic field generated by the first conductive member 422 may interact with the magnetic field of the magnetic assembly 440 to generate a first acting force (or a magnetic acting force) perpendicular to the optical axis of the lens 100, the elastic structure 421 may generate an elastic acting force perpendicular to the lens 100, the first acting force and the elastic acting force act on the carrier 410 at the same time, and the carrier 410 may move up and down under the driving of the first acting force and the elastic acting force, so as to drive the lens 100 to move up and down, thereby implementing auto-focusing of the lens 100 and/or compensating for shaking of the lens 100 in the vertical direction.

The first driving module 420 may include two first conductive members 422, and the two first conductive members 422 are disposed on two sides of the second supporting member 412 in a direction perpendicular to the optical axis of the lens 100. The two first conductive members 422 may have the same structure, for example, both first conductive members 422 may have the ring structure shown in fig. 9. Of course, the two first conductive members 422 may have a single rod structure or a double rod structure. In some embodiments, the two first conductive members 422 may have different structures, for example, one first conductive member 422 may have a ring structure, and the other first conductive member 422 may have a single rod structure or a double rod structure.

The magnetic assembly 440 may include a first magnetic member 441, a second magnetic member 442, and a third magnetic member 443, and the first magnetic member 441, the second magnetic member 442, and the third magnetic member 443 may be disposed on the first carrier 411.

A first conductive member 422 is positioned within the magnetic field generated by the first magnetic member 441, and a first conductive member 422, when energized, generates a magnetic field that interacts with the magnetic field generated by the first magnetic member 441 and pushes the second load bearing member 412.

Wherein the first magnetic member 441 may include a first magnet 4411 and a second magnet 4412, the magnetism of the first magnet 4411 is opposite to that of the second magnet 4412, for example, the first magnet 4411 may be a south pole, and the second magnet 4412 may be a north pole; or the first magnet 4411 may be a north pole and the second magnet 4412 may be a south pole. And the first magnet 4411 and the second magnet 4412 are disposed in a stacked manner in a direction parallel to the optical axis of the lens. A portion of one first conductive member 422 is disposed opposite the first magnet 4411 and a portion of one first conductive member 422 is disposed opposite the second magnet 4412. Taking the first conductive member 422 as an annular structure as an example, the first conductive member 422 may include a first portion and a second portion disposed in a direction perpendicular to the optical axis of the lens 100, the first portion being disposed opposite to the first magnet 4411, and a third portion and a fourth portion disposed in a direction parallel to the optical axis of the lens 100, the second portion being disposed opposite to the second magnet 4412.

The second magnetic member 442 is disposed opposite to the other first conductive member 422 in a direction perpendicular to the optical axis of the lens 100. So that the other first conductive member 422 is located in the magnetic field generated by the second magnetic member 442, the other first conductive member 422 can generate a magnetic field when being powered on, interact with the magnetic field generated by the second magnetic member 442, and generate a pushing force on the second bearing member 412, and the second bearing member 412 moves up and down relative to the first bearing member 411 under the action of the pushing force applied by the two second conductive members and the elastic force generated by the elastic structure.

The pushing force generated by the other first conductive member 422 on the second bearing member 412 may be equal to the pushing force generated by the one first conductive member 422 on the second bearing member 412, so that the two sides of the second bearing member 412 are stressed in a balanced manner and move up and down at the same speed. Of course, the pushing force of the other first conductive member 422 on the second bearing member 412 may be different from the pushing force of the one first conductive member 422 on the second bearing member 412, so that the two sides of the second bearing member 412 are unbalanced and move up and down at different speeds, thereby realizing the deflection of the second bearing member 412 by a certain angle.

In the embodiment of the present application, the second magnetic member 442 may have the same structure as the first magnetic member 441, for example, the second magnetic member 442 may include a third magnet 4421 and a fourth magnet 4422, the third magnet 4421 has a magnetic property opposite to that of the fourth magnet 4422, for example, the third magnet 4421 may have a south pole, and the fourth magnet 4422 may have a north pole; or the third magnet 4421 may be a north pole and the fourth magnet 4422 may be a south pole. And a third magnet 4421 and a fourth magnet 4422 are disposed in a stacked manner in a direction parallel to the optical axis of the lens.
