Disruption device, vehicle and method for disrupting wind vibration of vehicle

Abstract

The invention provides a spoiler for a vehicle and a method for spoiling the wind vibration of the vehicle. The turbulence device includes: a turbulence net fixing member, the turbulence net fixing member includes a fixed end fixedly arranged in the side window sash of the vehicle and a movable end which is pullably arranged in the side window sash, The fixed end has an accommodating cavity; one end of the turbulence net is rolled into the accommodating cavity of the fixed end, and the other end is connected to the movable end, and the turbulent net is set to follow the movable end in an operable or controlled manner. Pulling from a fully stowed state received within the side window sash to an unfolded state at least partially covering the area where the side window window of the vehicle is located, or returning from the unfolded state to the fully stowed state. According to the solution of the present invention, by installing a spoiler device in the side window frame, when the side window is opened and wind vibration is generated, the spoiler net rolled up in the accommodation cavity at the fixed end is pulled out, so as to play the role of spoiler , so that the vehicle has no wind vibration phenomenon at 30-110km / h.

Description

technical field [0001] The invention relates to the technical field of vehicle wind noise reduction, in particular to a spoiler device, a vehicle and a method for using the spoiler device to disrupt wind vibration of the vehicle. Background technique [0002] At present, consumers pay more attention to the ride comfort and driving safety of cars when purchasing cars, and the wind noise problem of cars has always been one of the comfort problems that consumers mainly complain about. In addition to increasing the driving resistance and increasing fuel consumption, the driving condition of the car with the window open can also cause hearing loss due to wind-induced noise, seriously affect the user experience, and easily lead to fatigue driving, and the low-speed airflow induces structural resonance radiation noise, resulting in unsteady loads Exciting the body vibration leads to the occurrence of unsafe factors. The problem of automobile wind vibration noise is widespread and ...
