Description

Lens, camera module and automobile Technical Field The utility model relates to the technical field of image pickup, in particular to a lens, an image pickup module and an automobile. Background The lens has the function of light transmission and is widely applied to various imaging fields such as vehicle-mounted, security and intelligent manufacturing. The lens is used as a precise optical component, and the imaging performance of the lens is sensitive at different temperatures. The lens comprises a lens barrel and a lens arranged in the lens barrel, the lens is usually arranged in the lens barrel in a mode of being mutually overlapped or embedded, and the lens is axially fixed through the spacer ring, the locking ring and the lens barrel. However, under a high-temperature environment, the lens, the space ring and the lens barrel are expanded and contracted in the axial direction, so that the sizes of the lens, the space ring and the lens barrel in the lens are slightly changed, and the lens, the space ring and the lens barrel are different in size variation caused by temperature change due to different materials of the lens, the space ring and the lens barrel, so that the focal length of the lens is deviated, namely the position of an imaging surface of the lens is deviated, the photosensitive chip cannot capture a clear imaging surface, and finally imaging blurring of the lens is caused. The influence is that the sensitivity of the lens under the high-temperature environment is not satisfied, so that the optical performance of the lens is influenced. Based on this, it is necessary to provide a lens capable of temperature drift compensation in a temperature change environment.
