Abstract: Provided is a camera module, including: a shell; a lens assembly movable relative to the shell; a focusing and driving assembly; an image stabilization and driving assembly; and a supporting and guiding assembly for supporting the lens assembly and guide a movement of the lens assembly. The supporting and guiding assembly comprises a first magnetic portion fixed to the lens assembly, a second magnetic portion fixed to the shell and spaced from and opposite to the first magnetic portion, and a ball provided between the first magnetic portion and the second magnetic portion. The lens assembly is connected to the shell through the supporting and guiding assembly in a rollable way. According to the present invention, the ball is arranged between the first magnetic portion and the second magnetic portion to guide the lens assembly to achieve restoration, thereby saving an inner space and facilitating assembling thereof.

Abstract: The invention provides a prism module and a folded lens. The prism module includes a housing having an accommodation cavity, a prism assembly, a rotation shaft for rotationally connecting the prism assembly and the housing, a driving assembly for driving the prism assembly to rotate around the rotation shaft and a restoring assembly for resetting the prism assembly. The restoring assembly includes a first magnet and a second magnet. The first magnet is fixed on the prism assembly, and the second magnet is fixed on the housing and is set opposite to the first magnet with distance. The prism module of the invention can realize the resetting of the prism assembly, with small space occupation and convenient for assembly.

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.
