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 optical system 2-50 may further include a first position sensing assembly configured to sense the movement of the supporting frame 2-54 (the first movable assembly) relative to the fixed assembly 2-FA, and the first position sensing assembly can be electrically connected to the first elastic elements 2-561 and the second elastic elements 2-562. Specifically, as shown in FIG. 12, the first position sensing assembly includes a first position sensor 2-SR, which is fixedly disposed on the supporting frame 2-54 and configured to sense the change in the magnetic field of the first driving magnets 2-MG1 so as to obtain the position or angle of the supporting frame 2-54 relative to the base 2-58.

In some embodiments, the first position sensing assembly may further include an inertial sensor (not shown in the figures), and the optical system 2-50 may further include a control circuit (not shown in the figure) configured to control the first driving assembly 2-DA1 to drive the supporting frame 2-54 to move relative to the base 2-58 according to an image signal captured in advance by the optical system 2-50 or an inertial signal from the inertial sensor.

Please refer to FIG. 14 and FIG. 15. FIG. 14 is an exploded diagram of the optical module 2-100 according to an embodiment of the present disclosure, and FIG. 15 is an enlarged schematic diagram of the optical system 2-50 according to an embodiment of the present disclosure.
