Abstract
The present invention provides an optical collection module, including a bracket, a rotating assembly, a driving assembly for driving the rotating assembly to rotate, and a restoring module. The rotating assembly includes a main body and a prism installed to the main body. The driving assembly includes a magnet and several coils. The main body is rotatably mounted on the bracket. The magnet is installed to one of the bracket and the main body; the coils are installed to the other of the bracket and the main body. The magnet includes two polar faces along the polarization direction; the coils are opposite to one of the polar faces of the magnet. The invention cooperates with the coils through the magnet to make the rotating assembly rotate in multiple directions relative to the mounting plate, thereby the moving range of prism increases accordingly.
