Abstract

The invention discloses a camera module with a heating device. The camera module comprises a camera lens assembly and the heating device, wherein the camera lens assembly comprises a lens cone, a lens group, a compression ring, a space ring and a lens base; parts or all of the compression ring, the lens cone, the space ring and the lens base are conductive parts, and parts or all of the compression ring, the lens group, the lens cone, the space ring and the lens base are heat conduction parts; the heating device comprises a coil for generating an alternating magnetic field, and an inverter or a transformer; and the heating device is used for generating a magnetic field so as to generate an eddy current in a conductive part in the camera lens assembly, and then the heat conduction parts in the camera lens assembly are heated so as to partially or completely heat the camera lens assembly. According to the camera module, the problem that a camera module in the prior art does not have a heating function or the heating function of an existing camera module is improved can be solved, and frost or water mist formed inside or outside the camera lens assembly can be quickly removed.

Description

technical field [0001] The invention relates to the technical field of camera devices, in particular to a camera module with a heating device. Background technique [0002] With the advancement of science and technology and the development of optoelectronic technology, the camera lens as an image acquisition port has ushered in rapid development in popular fields such as smart home, automatic driving, security monitoring, and drones. Since the camera lens is the core component of the optical imaging system , plays a key role in image quality. [0003] With the popularization of camera lenses in all walks of life, the application scenarios are becoming more and more extensive. For lenses used outdoors, when encountering cold or humid weather or when the environment is switched from hot to cold, due to the change of the temperature difference in the use environment, the air in the When water vapor encounters a cold lens, it condenses into a layer of fine water droplets, which...
