Abstract

The invention discloses an adaptive automobile antenna having resistance reduction and noise reduction functions. The adaptive automobile antenna comprises a steamline body appearance and an internal control component, wherein the steamline body appearance is in a half drop shape, the length-variable steamline body appearance comprises a steamline body shell first segment, a steamline body shell second segment and a tail cover, and the internal control component can be used for controlling a tail part of the steamline body appearance to correspondingly extend or shorten according to real-time automobile speed change. The simulation designed appearance for reducing resistance and reducing noise of the automobile antenna is arranged at a rear part of a car roof, so that the aerodynamic resistance and the aerodynamic noise of an automobile during high-speed running can be effectively reduced.

Description

technical field [0001] The invention relates to an adaptive automotive antenna with drag reduction and noise reduction functions, especially for passenger cars and commercial vehicles that need to run at high speed. Background technique [0002] With the development of social economy, cars have entered thousands of households. At the same time, people have higher and higher requirements for the appearance and function of cars. People realize the required functions by integrating cameras, radio antennas and mobile Internet communication antennas into the shark fin shell. The intelligence of automobiles makes more and more components to be integrated in the shark fin shell, and the size of the shark fin shell is also getting larger and larger. [0003] Due to the fixed size of the fin shells, some fin shell rears have a truncated shape that is abruptly interrupted before the airflow separates, which creates unnecessary drag and noise when the car is running at high speeds. ...
