LENS ASSEMBLY, CAMERA MODULE AND ELECTRONIC DEVICE

This application provides a lens assembly, a camera module, and an electronic device. The lens assembly includes a housing, a fastening base, a first lens, a second lens, and a driving mechanism. The fastening base is slidably connected to the housing and is located inside the housing. The first lens is fastened to the fastening base, the second lens is fastened to the housing, and the second lens is located on an image side of the first lens. The driving mechanism is configured to enable the housing to slide relative to the fastening base, and a distance between the second lens and the first lens in an optical axis direction of the lens assembly increases or decreases. On the one hand, a quasi-focus position of the lens assembly is changed by increasing or decreasing the distance between the first lens and the second lens, which is conducive to macro and telescopic photographing of the lens assembly, and greatly improves user experience. On the other hand, the housing is slidably connected to the fastening base, and a movement distance of the housing relative to the fastening base may be longer, which is more conducive to macro and telescopic photographing.
