[0139] One embodiment of this disclosure provides an imaging lens driving module, comprising an imaging lens, a lens carrier, a frame element, a sphere assembly, a circuit board, an elastic guide piece, and a driving unit. The imaging lens has an optical axis. The lens carrier is used to mount the imaging lens, and the frame element is disposed opposite to the lens carrier. The sphere assembly is disposed between the lens carrier and the frame element, wherein the sphere assembly is in physical contact with both the lens carrier and the frame element. The circuit board is disposed on the image side of the imaging lens. The elastic guide piece is used to connect the lens carrier and the circuit board, and the elastic guide piece includes a movable end, a fixed end, a connecting portion, and an elastic portion. The movable end is coupled and fixed to the lens carrier without relative displacement, the fixed end is coupled and fixed to the circuit board without relative displacement, and the connecting portion is connected to the movable end. The elastic portion connects the fixed end and the connecting portion, extends along a direction parallel to the optical axis, and includes at least two meandering branch segments. The at least two meandering branch segments extend toward the fixed end, and when viewed from a specific direction, they overlap. The driving unit is used to drive the lens carrier to move relative to the circuit board in a direction parallel to the optical axis or perpendicular to the optical axis, and the driving unit includes a first coil and a first magnet. The first coil is disposed at the movable end of the elastic guide plate, and the first magnet is disposed at a mounting part of the frame element, with the first magnet facing and corresponding to the first coil. In this way, the sphere assembly provides the lens carrier with a translational degree of freedom relative to the frame element in the direction parallel to the optical axis, and the elastic guide plate can reduce or even counteract the tensile force on the fixed end, improving the stability of the imaging lens driving module.

[0140] Specifically, the circuit board can be a printed circuit board (PCB), a flexible printed circuit board (FPC), a rigid-flex board, or a ceramic substrate, but is not limited thereto. The elastic conductor can be in the form of a thin sheet, but is not limited thereto. Furthermore, when the movable end moves with the lens carrier during autofocus, both the connecting part and the elastic part can provide deformation margin to ensure that the elastic conductor does not break and that the fixed end is not affected by tensile forces. Specifically, the movable end can be the point where the elastic conductor is adhered to the lens carrier, but is not limited thereto. The fixed end can be the point where the elastic conductor is soldered to the circuit board, but is not limited thereto. At least two meandering branch segments are in a meandering curve shape; the meandering curve shape can be a paperclip shape, a crab claw shape, etc., and the specific direction can be a direction orthogonal to the optical axis or a direction orthogonal to the elastic conductor, but is not limited thereto. In addition, the upper-wide and lower-narrow design of the elastic part can improve the performance of the elastic conductor in absorbing tensile forces.

[0141] Furthermore, the elastic portion of the elastic conductor may also include a node. The at least two meandering branches converge at the node as they extend toward the fixed end, and after converging at the node, the at least two meandering branches move away from the branch and further extend toward the fixed end, approaching each other. This facilitates a configuration design that balances electrical connection requirements with tensile strength buffering performance. The node configuration enhances the structural strength between the connected meandering branches, improving the elastic conductor's ability to absorb tensile forces during autofocus (AF) or optical image stabilization (OIS) movements.

[0142] Furthermore, the elastic portion may also include a reinforcing portion and an auxiliary restraint member. The reinforcing portion connects to at least one of the at least two meandering branch segments, and the auxiliary restraint member is coupled to the reinforcing portion and the at least one of the at least two meandering branch segments, such that there is a second included angle between the reinforcing portion and the at least one of the at least two meandering branch segments. The configuration of the reinforcing portion enhances the structural strength of the connected meandering branch segments and improves the performance of the elastic conductor sheet in absorbing tensile forces. Specifically, the reinforcing portion may be a side facade extending from the meandering branch segment after it has turned at an angle, but this is not a limitation.

[0143] Furthermore, the elastic wire piece may further comprise a primary restraining member. The primary restraining member is coupled to the connecting portion and the elastic portion, and makes the connecting portion and the elastic portion form a first included angle. Thereby, the bending degree of the elastic wire piece can be restricted to conform to the wiring design in a limited space and improve the space utilization efficiency. Specifically, the primary restraining member may be an iron piece with a turning angle, which is used to restrict the bending degree of the elastic wire piece, but is not limited thereto.

[0144] Specifically, the driving unit may further comprise a second coil. The second coil is disposed on a surface of the circuit substrate, and the first magnet faces the first coil and the second coil simultaneously and is arranged correspondingly to the first coil and the second coil. Specifically, the Lorentz force generated by the electromagnetic interaction between the first coil and the first magnet pushes the lens carrier to move relative to the frame element in the direction parallel to the optical axis.

[0145] Furthermore, the driving unit may further comprise a third coil and a second magnet.
