Embodiment Construction

[0052] figure 1 A schematic schematic showing a simplified model of window-opening wind noise generation for a vehicle. Such as figure 1As shown in Fig. 1, when the window is opened at high speed, the tangential flow at the front edge of the vehicle window falls off due to the lack of a surface to continue to adhere to, resulting in a vortex, which moves further backwards and expands, impacting the cavity in the car and the rear edge of the window . The cavity in the car is impacted by the vortex, and the regular expansion and contraction of 10-20Hz (referred to as pressure fluctuation) occurs due to the inability to release the pressure in time. The vortex impinging on the rear edge of the window is reflected by the wall of the rear edge, forming a positive excitation to the front vortex, which further intensifies the vortex shedding at the front edge of the window. It is precisely because of the violent impact and extrusion of the vortex on the cavity in the car that the ...

Abstract

The invention provides a jet flow device and a vehicle. The jet flow device comprises a jet flow nozzle used for jetting air flow, Wherein the jet flow nozzle is arranged at the front edge of a vehicle window; and an airflow outlet of the jet flow nozzle faces the rear edge of the vehicle window so as to enable the airflow jetted from the jet flow nozzle to be jetted from the front edge of the vehicle window to the rear edge of the vehicle window, and wind vibration vortexes are prevented from being formed between the front edge and the rear edge of the vehicle window by utilizing the airflowjetted from the jet flow nozzle. According to the scheme of the embodiment of the invention, the jet flow device destroys conditions for generating wind vibration by adopting a vehicle window front edge jet flow mode, so that the roar of the vehicle is reduced, the influence on the front view after the window is opened is extremely small, and the attractiveness of the vehicle window is not influenced basically. Particularly, after the vehicle window is closed, the attractiveness of the vehicle window is not influenced due to the fact that the airflow inlet and the airflow outlet are hidden, and when the vehicle window is opened, the attractiveness is not influenced greatly due to the fact that the design of the jet flow nozzle is basically flush with one side of the window frame.

Description

technical field [0001] The invention relates to the technical field of wind noise reduction for vehicles, in particular to a jet device and a vehicle. Background technique [0002] When the car is running at high speed, the friction between the airflow and the body will produce wind noise. The wind noise outside the car is transmitted to the inside of the car and becomes the main noise source in the car. When the car window is opened, the inside of the car is connected with the outside of the car, and a cavity is formed inside the car body. At this time, the airflow acts on the car body, which will form a roar in the car, that is, wind vibration noise. [0003] At present, consumers pay more attention to the ride comfort and driving safety of the car when purchasing a car. The roar of the car has always been one of the comfort issues that consumers mainly complain about. In addition to increasing the driving resistance and increasing fuel consumption, the driving condition...
