Abstract

Technical Field
[0001] The utility model belongs to the technical field of automobile decorations and relates to a heating and defogging power circuit structure for a camera area on a vehicle pillar decoration plate. Background Art
[0002] With the improvement of the application of automobile intelligence, more and more vehicles are applying assisted driving and surround view functions. Cameras are essential components for realizing the above functions. Vehicles realize assisted driving and surround view functions through the image information outside the vehicle collected by the camera. The viewing angle area of the camera to collect images is not allowed to be blocked, otherwise the assisted driving function will not be able to be used normally. Because the camera generates heat when working, the air in the cavity enveloping the camera is heated, while the temperature of the pillar outer panel is still low. When the temperature difference between the air in the cavity enveloping the camera and the pillar outer panel reaches the fogging condition, fog will form in the camera window area of the pillar outer panel, thereby blocking the camera and the assisted driving function cannot be used normally. Although the fog will dissipate after a period of time and the assisted driving function will resume normal use, it gives customers a poor experience. Some customers will also think that there is a problem with the quality of the car, which affects the customer experience and the reputation of the car manufacturer. The camera area on the outer panel of the pillar needs to be defogged. Heating with a heating wire is one of the methods. The heating wire needs to have an electrical circuit connected to the body circuit. The existing conductive circuit connecting the heating wire requires the wire terminal to be soldered to the heating wire, which requires welding equipment. The overall structure is complex and the manufacturing cost is high. Utility Model Content
