Abstract

The disclosure relates to the technical field of optical systems, and relates to a lens module and an electronic device. The lens module includes a bearing structure, a support frame, a lens barrel, and an adjusting mechanism. The bearing structure includes an upper shell and a base that are connected with each other. In the lens module of the present embodiment, by adopting a bent portion spaced apart from the side wall to cooperate with the focus coil, the internal space of the upper shell can be fully utilized to make the structure between the focus assembly and the upper shell more compact, thereby making the overall structure of the lens module more compact.
