Device for weakening windowing roar and vehicle

Abstract

The invention provides a device for weakening windowing roar and a vehicle. The device for weakening the windowing roar comprises a stand column, and the stand column stretches across a window of a vehicle window and is arranged to move in a controlled or operable mode when the vehicle window is opened so as to divide the window into two parts. According to the scheme, the window is divided into two parts by moving the stand column, which means that the window is divided into two parts, and a wind noise in the vehicle is reduced and the window opening roar is weakened under the condition thatan opening degree of the vehicle window is not adjusted. Moreover, the stand column is hidden or exposed at a B-pillar window frame in the vehicle so that a purpose that attractiveness of the outer vehicle body is not influenced is achieved on the premise of not influencing the sealing performance of the window frame, an appearance of the vehicle body does not need to be changed, and a view in front of the vehicle window is not influenced basically. And the device is simple and ingenious in structural design.

Description

technical field [0001] The invention relates to the technical field of wind noise reduction for vehicles, in particular to a device and a vehicle for reducing the roar of window opening. 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 fue...

AI Technical Summary

Problems solved by technology

In addition to increasing the driving resistance and increasing fuel consumption, the driving condition of the car with the window open will damage the hearing, seriously affect the user experience, and easily lead to fatigue driving, and the low-speed airflow induces structural resonance radiation noise, which generates unsteady load excitation. Vibration of vehicle body leads to occurrence of unsafe factors

The problem of car roar is widespread and has not been effectively solved
