Description

Camera module Technical Field The utility model relates to the technical field of camera shooting, in particular to a camera shooting module. Background Along with the popularization of automation and intelligence of automobiles, an on-board monitoring system becomes one of the standard of contemporary automobiles, and a camera module becomes one of indispensable elements in the on-board monitoring system. The camera module applied to the automobile generally has defrosting and defogging functions, and the defrosting and defogging functions are realized mainly by adding a heating element in the camera module to heat the lens. However, because the heating element is arranged outside the lens, and the heating element is of a flexible structure, the position of the heating element needs to be controlled when the lens is assembled with the shell, and the heating element is prevented from influencing the alignment assembly of the lens and the shell, so that the assembly efficiency and the assembly precision of the lens and the shell are seriously influenced. And the electric connection of the heating element is complicated in a welding mode, so that the cost and the yield of the camera module are further affected. Disclosure of utility model The utility model aims to at least solve one of the technical problems in the prior art, and provides an image pickup module which comprises a lens, a chip assembly, a heating element and a flexible circuit board, wherein the lens comprises a lens barrel and a lens accommodated in the lens barrel, the barrel wall of the lens barrel is provided with a wire groove, the chip assembly comprises a first circuit board, a photosensitive chip and a row of plug connectors, the first circuit board comprises an upper surface facing the lens and a lower surface deviating from the upper surface, the photosensitive chip is arranged in the middle of the upper surface and faces the lens barrel, the row of plug connectors are arranged on the lower surface, the upper shell is of a hollow structure with two open ends, the upper shell is fixedly connected with the outer side wall of the lens barrel, the bottom surface of the upper shell is arranged on the periphery of the upper surface through first glue, the number of the first glue is multiple and is distributed at intervals, an avoidance groove is formed between the adjacent first glue, the heating element comprises a heating sheet and a flexible circuit board, the heating sheet is arranged in the lens barrel and is close to the lens, one end of the flexible circuit board is sequentially connected with the lens barrel, and the other end of the flexible circuit board passes through the wire groove and the wire groove to be connected with the row of plug connectors.
