Abstract: The invention provides a lens module, including: a lens assembly having an optical axis; a first bracket; a first elastic plate suspending the lens assembly in the first bracket; a second bracket; a suspending wire; and a driving assembly for driving the lens assembly to move along the optical axis relative to the first bracket, and for driving the lens assembly to move in a direction perpendicular to the optical axis. The second elastic plate is fixed on the second bracket, and includes a fixed part fixedly connected to the second bracket and a deformation part. The deformation part performs elastic deformation along the optical axis relative to the fixed part for reducing the bending force of the suspending wire. Compared with prior art, a lens module of the present invention has an improved image optical stabilization function.

Abstract: A lens prism module relates to the field of shooting equipment and includes a fixed base, a rotating base, a mounting base, a prism, and a driving assembly. The rotating base includes rotating shafts rotatably connected with the fixed base and a connecting shaft rotatably connected with the mounting base. An axis of the connecting shaft is perpendicular to an axis of each rotating shaft. An accommodating groove accommodating the connecting shaft is provided on the mounting base. Positioning holes are on a top surface and a bottom surface of the accommodating groove. Two ends of the connecting shaft are separately rotatably disposed on a corresponding positioning hole. On a premise of realizing rotation of the mounting base, a part of the connecting shaft is hidden in the accommodating groove to reduce a volume of an overall structure of the lens prism module, thereby realizing requirements of miniaturization design.

Abstract: A lens prism module relates to the field of shooting equipment and includes a fixed base, a rotating base, a prism, and a driving assembly. The rotating base includes rotating shafts connected with the fixed base. The rotating base is recessed to form rotating grooves. A bottom portion of each rotating groove includes supporting surface structures disposed obliquely with respect to an axis of the rotating shafts. One end of each rotating shaft is of a curved surface structure. Each curved surface structure is tangent to a corresponding supporting surface structure for realizing rotation of the rotating base, which reduce resistance of rotation, reduces a driving force for driving rotation of the rotating base, so that the lens prism module responds quickly when performing an optical image stabilization function. Meanwhile, it limits shaking of the rotating shafts and the rotating shafts are stably rotatably connected with the rotating base.
