Abstract: A lens driving device includes first and second support frames, lens barrel, anti-shake magnets, anti-shake coils, flexible PCB, metal sheets, and support assembly including support member and first and second guiding posts. Support member includes support plate and first and second support walls. First soft protruding rubbers are respectively provided at positions of top surface of first support frame corresponding first support walls, and second soft protruding rubbers are respectively provided at positions of inner wall of second support frame corresponding to two sides of each second support wall. Compared with the prior art, lens driving device of the present disclosure makes impact limit position of first support walls closer to deflection axis position in first direction, and makes impact limit positions of second support walls closer to deflection axis position in second direction to reduce speed of limit impact, thereby reducing risk of generating particles due to impact.

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 camera lens includes a mounting housing, a lens module, an image stabilization module, first and second support shafts fixed to the mounting housing opposite to each other along one of diagonals of the mounting housing, and third and fourth support shafts fixed to the frame opposite to each other along another diagonal of the mounting housing. The mounting housing is formed by sequentially connecting first to fourth frame plates. The image stabilization module includes a frame, a movable frame, first and second image stabilization coils, and first and second magnets. The movable frame has first to fourth rotation holes. The first to fourth support shafts are respectively rotatably fit within the first to fourth rotation holes. The camera lens of the present disclosure can solve the problems of great process difficulty and high cost in the related art when the camera lens performs the optical image stabilization.

Abstract: A lens prism module related to the field of shooting equipment and includes a fixed base, a rotating base rotatably connected with the fixed base, a prism disposed on the rotating base, and a driving assembly for driving the rotating base to rotate. The rotating base includes rotating shafts rotatably connected with the fixed base. The rotating base is recessed to form rotating grooves. A bottom portion of each of the rotating grooves is configured as a first curve surface structure. A front end of each of the rotating shafts is configured as a second curve surface structure. The front end of each of the rotating shafts is disposed in a corresponding rotating groove for realizing rotation of the rotating base, which allows the rotating base to rotate on the rotating shafts and makes the lens prism module respond quickly when performing the optical image stabilization function.

Abstract: A lens driving device includes a lens module, a first support frame, a second support frame sleeved on the first support frame, a support assembly for suspending the first support frame inside the second support frame, a first flexible printed circuit board (PCB) including folding portions, a second flexible PCB opposite to and independent from the first flexible PCB, and a driving assembly. Each folding portion includes a first fixing portion attached to the first support frame, a second fixing portion attached to the shell, and bent portions connecting the first fixing portion with the second fixing portion by bending. The two flexible PCBs are separately provided in the lens driving device to prevent the risk of disengagement when the two flexible PCBs move, and the folding portions prevent the first flexible PCB from being pulled by the movement of the lens module to be disconnected.
