Abstract

The invention relates to a lens module. The lens module comprises a lens (11) and a lens base (12) fixedly connected with the lens (11); a lens barrel (111) of the lens (11) is provided with a connecting portion (1111) welded to the lens base (12); and an annular groove (1111a) is arranged on the side of the connecting portion (1111) along the axial direction of the lens (11). The connection between the lens and the lens base is achieved by means of welding, therefore, the problem of influence on the lens precision caused by glue shrink and the like generated by the curing process of the glueis avoided; especially when connected by laser welding, the welding spot area is small; and the generated internal stress is correspondingly reduced through the evenly distributed welding points, which benefits ensuring the structural precision and stability of the lens module disclosed by the invention.

Description

technical field

[0001] The invention relates to the field of optics, in particular to a lens module. Background technique

[0002] With the development of artificial intelligence and the emphasis on car driving safety, the assembly requirements of vehicle-mounted modules (cameras) continue to increase, and it has become a trend to improve the reliability of modules (cameras) and reduce costs; at present, ordinary vehicle-mounted modules (Camera), in the assembly process of the lens and the mirror base, it is mainly fixed by threads and glue; or the lens and the mirror base are only fixed by glue. However, in the existing assembly method of the mirror base and the lens, glue is used for bonding, so that the curing time of the glue is longer in the manufacturing process, which prolongs the production cycle. Moreover, as time increases, the adhesive force of the glue will decrease, which will affect the reliability of the product after a long time. In addition, as the require...
