Abstract: An optical driving assembly includes an optical element having an optical axis, an optical sensor, and a driving module driving optical sensor to translate along a direction perpendicular to the optical axis. The driving module includes a fixation member provided with a moving cavity, a moving member provided in the first moving cavity and movably connected to the fixation member along a first direction and provided with a second moving cavity, a supporting member provided in the second moving cavity and movably connected to the moving member along a second direction and supporting the optical sensor, and first and second driving assemblies. The first and second driving assemblies include first and second shape memory alloy wires. The optical sensor can linearly move in two directions perpendicular to the optical axis, achieving optical image stabilization and independent movements in two directions that are not affected by each other.
