  • Patent number: 9857551
    Abstract: A lens module includes a lens barrel, and a lens group received by the lens barrel. The lens barrel includes an first supporter, a second supporter extending vertically from the first supporter, and a receiving space formed by those supporters, the first supporter having a light aperture, the second supporter having an inner surface facing the receiving space. The lens group includes a first lens abutting against the inner surface of the second supporter, a second lens stacked on the first lens and abutting against the inner surface of the second supporter, a third lens stacked on the second lens and abutting against the inner surface of the second supporter, and a fourth lens stacked on the third lens and abutting against the inner surface of the second supporter, for ensuring the concentricity among the lenses and keeping the lens group coaxial with the lens barrel.

  • Patent number: 9817205
    Abstract: The present disclosure discloses a lens module. The lens module includes a lens barrel and a lens group. The lens group is installed inside the lens barrel. The lens barrel includes a first barrel wall extended horizontally and a second barrel wall bended and extended from the first barrel wall. The lens module also includes a stop and a press ring. The stop is fixed on the first barrel wall. The press ring is located on the stop and presses on the stop. The stop and the lens group are lined up in turn from object side to image side. The length of the lens barrel is reduced due to the stop and the press ring, when shaping of lens barrel is being done, production difficulty of shaping is decreased, and the yield of qualified lens barrel is increased.
