Abstract

The invention relates to a camera module which comprises a plate spring structure (1), a lens, a lens base (2), a circuit board (3) and a bottom plate, wherein the lens, the plate spring structure (1), the circuit board (3) and the bottom plate are sequentially connected with the lens base (2); and the plate spring structure (1) is positioned between the lens seat (2) and the circuit board (3). The plate spring structure supports the circuit board, can ensure the balance of internal and external clamping forces after the circuit board AA is completed, prevents the circuit board from deviating due to downward pressure during welding, and is beneficial to ensuring the imaging quality of the module. And meanwhile, the plate spring structure can be beneficial to preventing the fixing material from flowing downwards, and pollution to the interior of the module is avoided.

Description

technical field [0001] The invention relates to the field of optics, in particular to a camera module. Background technique [0002] Recently, with the rapid development of imaging modules, their application fields have become more and more extensive, and the requirements for their imaging quality have become higher and higher. For example, in the field of vehicle-mounted camera modules, higher requirements are placed on the imaging effects of the camera modules. Therefore, in the assembly process of the high-pixel camera module, the assembly process requirements are more stringent, especially the control of focusing precision and the protection of dust will directly affect the image quality and pass rate, which puts forward higher requirements for the structure of the module. Require. Correspondingly, in order to meet the high requirements for the camera module, the camera module needs to have the function of precise zooming in a short time. Therefore, a leaf spring is a...
