Patent number: 7751131Abstract: A lens module including a lens barrel, multiple lenses, and multiple cushions is provided. The lens barrel has an assembling opening, an inner wall, and multiple positioning structures. The positioning structures are integrally formed on the inner wall. An internal diameter of the positioning structure adjacent to the assembling opening is greater than an internal diameter of the positioning structure far away from the assembling opening. In addition, the lenses are respectively fixed in the corresponding positioning structure along an assembling direction. Each cushion is disposed in a pitch between two adjacent lenses, and each lens assembled in the lens barrel is disposed at a predetermined position through the positioning structures and cushions.Type: GrantFiled: August 20, 2008Date of Patent: July 6, 2010Assignee: AV TECH CorporationInventors: Chun-Ru Huang, Chien-Yueh Chen
