Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 to 3, the embodiment provides a heating deicing, defrosting and fogging structure for a vehicle-mounted lens, the heating deicing, defrosting and fogging structure is arranged in a front camera shell 1 and a rear camera shell 2, a sealing ring 3 is arranged at a joint of the front camera shell 1 and the rear camera shell 2, the front camera shell 1 and the rear camera shell 2 are clamped and connected to form a sealed cavity, a first PCB 4 and a second PCB 5 are placed in the cavity, the first PCB 4 is connected with a lens barrel 6, the other end of the lens barrel 6 is embedded with a lens 7, the lens 7 penetrates through the front camera shell 1 and protrudes outwards, the second PCB 5 is connected with a connector 8, and the connector 8 penetrates through the rear camera shell 2 and is communicated with an external power supply.

The lens barrel 6 is sleeved with a flexible heating module 9, the flexible heating module 9 is electrically connected with the first PCB 4, the first PCB 4 is connected with the second PCB 5 through a wire, so far, the flexible heating module 9 obtains power through the first PCB 4, the flexible heating module 9 has the working characteristic that the heat is generated when the flexible heating module is electrified, the lens barrel 6 conducts heat to the lens 7, the temperature of the lens 7 can be gently promoted, and therefore heat energy is provided when the visual field of the camera is covered by ice, snow and fog, the lens 7 is cleaned, and the visual field is clear.
