The invention relates to a wind resistance reducing device, method and system and a vehicle, and relates to the technical field of vehicles. The wind resistance reducing device (10) comprises a telescopic piece (11) and a driving mechanism (12). The telescopic piece (11) is arranged at the tail part of the vehicle (1); the driving mechanism (12) is used for driving the telescopic piece (11) to be switched between an extending state and a retracting state relative to the vehicle (1); the length of the vehicle (1) when the telescopic piece (11) is in the stretching-out state is larger than the length of the vehicle (1) when the telescopic piece (11) is in the retracting state. As a result, it is possible to achieve lower wind resistance while maintaining a graceful shape of the vehicle.
本申请涉及一种降风阻装置、方法、系统及车辆,涉及车辆技术领域。该降风阻装置(10)包括:伸缩件(11)和驱动机构(12);伸缩件(11)设置于车辆(1)的尾部;驱动机构(12)用于驱动伸缩件(11)相对于车辆(1)在伸出状态与缩回状态切换;车辆(1)在伸缩件(11)处于伸出状态下的长度大于在伸缩件(11)处于缩回状态下的长度。由此,可以在车辆保持优美造型的同时实现更低的风阻。
