摘要： An optical element driving mechanism includes a fixed assembly, a movable assembly, a driving assembly and a circuit assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The driving assembly includes a first coil group which has a plurality of first coils and a magnetic module which has a magnetic element and a first conductive element. The circuit assembly includes a first circuit member electrically connected to the first conductive element and a second circuit member electrically connected to the first coils. When the magnetic module is located in different positions relative to the first coil group, the first conductive element is electrically connected to different first coils in sequence, so that the first coil is electrically connected to the first circuit member and the second circuit member, and other first coils remain open.

摘要： The present invention relates to an aperture unit having an optical axis. The aperture unit includes a fixed portion, a guiding element, a first blade and a driving assembly. The guiding element is movably connected to the fixed portion, and the first blade is movably connected to the guiding element and the fixed portion. The driving assembly is disposed on the guiding element for driving the guiding element to move relative to the fixed portion in a first moving dimension. When the guiding element moves relative to the fixed portion in the first moving dimension, the first blade is driven by the guiding element to move relative to the fixed portion in a second moving dimension, and the first moving dimension and the second moving dimension are different.

摘要： A driving mechanism is provided, including a fixed part, a movable part connected to the fixed part, and a driving assembly configured to impel the movable part relative to the fixed part, so that the driving mechanism is switchable between an open state and a closed state. The fixed part has a plurality of holes. When the driving mechanism is in the open state, light propagates through the driving mechanism via the holes, and when the driving mechanism is in the closed state, the holes are blocked by the movable part.
