Problems solved by technology
Different types of vehicle-mounted cameras correspond to different types and specifications of lenses. When replacing a vehicle-mounted camera, because the size of the lens is different from the total optical length, a camera housing that meets the size of the external thread column of the lens is required for matching during installation. At the same time, due to the requirements of different optical total lengths of the lens, it is necessary to adjust the optical total length of the lens after installation.

The embodiment of the invention provides a vehicle-mounted camera lens mounting structure which comprises a shell, a photosensitive assembly arranged in the shell and a lens arranged on the shell opposite to the photosensitive assembly, a threaded hole is formed in the shell, an external threaded column is arranged at one end of the lens, and the structure further comprises a reducing sleeve. The outer side wall and the inner hole wall of the reducing sleeve are respectively provided with an external thread and an internal thread, and the reducing sleeve is in threaded connection with the threaded hole in the shell through the external thread and is in threaded connection with the external threaded column at one end of the lens through the internal thread. In practical application, different reducing sleeves can be replaced according to practical needs to be matched with lenses of different specifications, so that the lenses are convenient to replace, the trouble of replacing an adaptive shell is saved, the replacement difficulty is reduced, meanwhile, a plurality of reducing sleeves with different axial lengths can be designed for selection, and the cost is reduced. The optical total length of the lens can be flexibly adjusted according to different requirements, so that the lens can be conveniently used after being replaced, and platform interchange of the lens is realized.
Description
technical field [0001] Embodiments of the present invention relate to the field of vehicle camera technology, and in particular to a vehicle camera lens installation structure. Background technique [0002] A vehicle camera is an electronic device installed in a vehicle to monitor and record traffic and driving conditions, providing a safe guarantee for vehicle driving. Existing vehicle-mounted cameras usually include a housing, a lens disposed at one end of the housing, and a photosensitive component disposed in the housing. The inner end of the lens is provided with an externally threaded column for corresponding screw connection with the threaded hole provided on the housing. The screwing depth of the external threaded column of the lens in the threaded hole can adjust the distance between the lens and the photosensitive component accordingly to achieve the best shooting effect. [0003] As vehicle-mounted cameras become more and more popular in people's daily traffic an...
