The invention discloses an active resistance reduction shark fin antenna, a method and an automobile, and belongs to the technical field of automobile resistance reduction. Comprising a shark fin antenna, a pressurization gas storage module and a control module, the top of the shark fin antenna is provided with a plurality of gas nozzles, the shark fin antenna is internally provided with a gas injection module, and the gas nozzles are communicated with the gas injection module; a lifting module is arranged at the bottom of the shark fin antenna; the pressurizing gas storage module is communicated with the gas injection module; the control module is used for obtaining a vehicle speed signal and controlling the operation states of the air injection module, the lifting module and the pressurization air storage module according to the vehicle speed signal. The height and the jet speed of the shark fin antenna at the top of the automobile can be actively regulated according to the change of the running speed, the aerodynamic resistance of the whole automobile is reduced, and the purpose of reducing energy consumption is achieved; the problem that wind resistance of an existing vehicle is difficult to reduce is solved.

    本发明公开了一种主动式减阻鲨鱼鳍天线、方法及汽车,属于汽车减阻技术领域。包括鲨鱼鳍天线、增压储气模块和控制模块,所述鲨鱼鳍天线的顶部开设有多个喷气口,所述鲨鱼鳍天线的内部设置有喷气模块,所述喷气口与所述喷气模块连通;所述鲨鱼鳍天线的底部设置有升降模块;所述增压储气模块与所述喷气模块连通;所述控制模块用于获取车速信号,根据车速信号控制所述喷气模块、所述升降模块和所述增压储气模块的运行状态。能够根据行驶速度的变化,主动调控汽车顶部鲨鱼鳍天线的高度和喷气速度,降低整车气动阻力,达到减少能耗的目的;解决现有车辆风阻难以降低的问题。
