    Abstract: A driving mechanism for driving an optical element is provided, including a fixed part, a movable part, a bobbin, and a driving assembly. The movable part is movably connected to the fixed part and holds the optical element. The bobbin is disposed on the fixed part or the movable part. The driving assembly drives the movable part to move relative to the fixed part and has a coil disposed on the bobbin. The fixed part has a main body, and the main body forms a recess for receiving the bobbin.

    Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed part, a movable part, a first driving assembly, and a strengthening member. The fixed part includes a first base. The movable part is connected to an optical element with an optical axis. The movable part is movable relative to the fixed part, and the movable part is accommodated in the fixed part. The first driving assembly drives the movable part to move relative to the fixed part. The first driving assembly is disposed in the first base. The strengthening member is embedded in the first base. When viewed along a direction that is perpendicular to the optical axis, the strengthening member at least partially overlaps the first driving assembly. When viewed along the optical axis, the strengthening member does not overlap the first driving assembly.

    Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed portion, a first movable portion, a second movable portion, a first driving assembly, and a second driving assembly. The first movable portion is movable relative to the fixed portion. The second movable portion is used for holding an optical element having a main axis, and is movable relative to the first movable portion. The first driving assembly is used for driving the first movable portion to move in a first dimension relative to the fixed portion, and the second driving assembly is used for driving the second movable portion to move in a second dimension relative to the fixed portion. The first dimension and the second dimension are different.

    Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a movable part and a fixed part. The movable part holds an optical element with an optical axis and moves relative to the fixed part. The fixed part includes a bottom unit, which is integrally formed. The bottom unit includes a base member, a circuit member, and a driving coil assembly. The driving coil assembly is electrically connected to the circuit member. The circuit member and the driving coil assembly are located at the base member. The driving coil assembly includes a connection wire, a plurality of first driving coils, and a plurality of second driving coils. The first driving coils are connected via the connection wire. The second driving coils are located between the first driving coils and the circuit member. When viewed along a direction that is perpendicular to the optical axis, the second driving coils partially overlap the connection wire.
