Technical Field

Background

In the related art, the motion camera includes a main board, a lens module communicatively connected to the main board, and a housing accommodating the main board and the lens module. Wherein the housing is made of a plastic material and only the partial assembly is made of hardware made of a metal material. Or the movement is formed by die casting of an aluminum alloy material, core components such as the main board and the lens assembly are fixed on the movement, and the outer surface of the movement is coated with plastic to form a shell.

In the working process of the motion camera, the main board and the lens module generate a large amount of heat, and the working performance of the main board and the lens module is reduced by the heat, so that the operation experience of a user is influenced.
