Embodiment Construction

[0019] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0020] Referring to the accompanying drawings, the vehicle vibration and noise reduction system according to the embodiment of the present invention includes a duct 10 connected to the interior of the vehicle at one end, and a blower assembly 20 for forcing out the air entering the duct 10 in the vehicle.

[0021] The air intake 12 installed at one end of the duct 10 is provided at the rear of the vehicle, which allows the interior air of the vehicle to be introduced into the duct 10, and if the vehicle has a rear window 8 installed behind the rear seat, the air intake can be provided at the rear under the windowsill. The air inlet 12 has a mesh-type cover to prevent foreign materials from entering the conduit 10 . The duct 10 serves as a passage through which air entering the interior of the vehicle from the intake port 12 is exhausted to the ou...

Abstract

The present invention relates to a system and method for reducing buffeting noise of a vehicle, the buffeting noise reducing system comprises: a duct configured for air to pass therethrough, with an air intake at one end disposed inside the vehicle, a blast blower component comprises a housing, the housing is used as air chamber and connected to the other end of the duct, and an air outlet that is connected with an outer side of the vehicle, a blower fan is mounted inside of inner the blower fan, a blower motor for rotating the blower fan, wherein, when generating buffeting noise, the inner air of the vehicle guided by an air inlet in the pipeline is discharged to the outer side of the vehicle through driving of the fan motor, thus reducing the noise.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2006-0105832 filed on October 30, 2006 at the Korean Intellectual Property Office, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to vibration noise reduction systems and methods in vehicles. In particular, the present invention relates to a vehicle vibration noise reduction system and method that reduces vibration noise generated when an air intake such as a sunroof or a rear side door window on a side of a vehicle is opened. Background technique [0004] During driving, when only the sunroof is open or only one rear side door window is open, there is a problem of generating vibration noise. The problem is known to be caused by vibrations caused by vortices of air entering through open windows and sunroofs. However, such vibration noise can be eliminated when other air in...
