## Abstract

The present invention provides a lens assembly and a mobile terminal. The lens assembly includes a lens and a protective casing. The lens and the protective casing are fixedly connected to the mobile terminal separately. The lens is sheathed in the protective casing. A spacing exists between the protective casing and the lens. In the lens assembly and the mobile terminal provided in this embodiment, when the lens assembly is impacted, the protective casing receives the impact first and is deformed. Without direct connection or contact between the lens and the protective casing, a force received by the protective casing will not be directly transmitted to the lens, and the lens will not be pressed to deform by the protective casing, thereby avoiding a circumstance in which the deformation of the lens makes the mobile terminal unable to accurately recognize an obstacle.

## Claims
