摘要

A photosensitive element driving mechanism includes a fixed assembly, a first movable assembly and a first driving assembly. The first movable assembly is movable relative to the fixed assembly, and the first movable assembly is configured to be connected to a photosensitive element. The photosensitive element corresponds to an optical element. The first driving assembly is configured to drive the first movable assembly to move relative to the fixed assembly. The first movable assembly includes a heat dissipation structure corresponding to the first driving assembly, the optical element or the photosensitive element.

說明書

The outer ring portion of the fourth elastic element 2-106 is connected to the frame 2-104, the outer ring portion of the fourth elastic element 2-110 is connected to the base 2-112, and the inner ring portion of the fourth elastic element 2-106 and the inner ring portion of the fourth elastic element 2-110 are connected to the upper and lower sides of the holder 2-108 so that the holder 2-108 is suspended in the frame 2-104. In addition, the second movable assembly 2-MA2 further includes four suspension wires 2-116 (the third elastic elements), one end of the suspension wire 2-116 is connected to the fourth elastic element 2-106, and the other end is connected to the base 2-112, so that the frame 2-104 and the holder 2-108 can move in the X-axis or the Y-axis.

The third driving assembly 2-DA3 includes a circuit board 2-114 and second driving magnets 2-MG2, and the circuit board 2-114 has a third driving coil 2-1141, so that the third driving assembly 2-DA3 is configured to drive the second movable assembly 2-MA2 to move in the X-axis or the Y-axis relative to the base 2-112.
