  • Patent number: 11516400
    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.

  • Patent number: 11490014
    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.

  • Publication number: 20220146782
    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.
