Front air-rectifying structure of automotive vehicle

Abstract

A front air-rectifying structure of an automotive vehicle is provided which can properly suppress the vibration transmissoin to a shutter unit, without damaging the air-guide performance for a shutter unit, thereby preventing any problem from happening to the move of flaps. The front air-rectifying structure of the automotive vehicle comprises an air guide member to guide air flowing in through a grille opening portion toward to the shutter unit. The shutter unit comprises plural flaps, a shutter frame member, and a second support portion to support the air guide member. The air guide member is formed integrally by a lower face portion positioned between an upper grille opening portion and the flaps, a first fixation portion fixed to a first support portion of a shroud member, and a second fixation portion fixed to a second support portion of the shutter unit. The lower face portion in a state of fixation to the second support portion is spaced apart upward from the shutter frame member.

Description

technical field [0001] The present invention relates to an automobile front rectification structure provided with a shutter unit for controlling the flow of outside air flowing into an engine room from, for example, a grill opening formed at the front of the vehicle. Background technique [0002] The front part of the automobile is configured such that outside air can be introduced into the engine room through the opening formed in the grille opening of the bumper, thereby cooling a heat exchanger such as a radiator or an intercooler, and the engine. [0003] In addition, recently, in order to further improve fuel consumption and reduce exhaust gas, automobiles equipped with a louver unit for controlling the flow of outside air flowing in from a grill opening are known. [0004] The louver unit includes a plurality of flaps that are opened and closed according to the oil temperature of circulating oil circulating in the engine and the temperature of cooling water or the vehi...

AI Technical Summary

Problems solved by technology

[0018] However, in Patent Document 4, since the fins are located in front of the siren device, the fins vibrate due to the sound pressure of the siren to generate abnormal noise, or the vibration of the fins is transmitted to the drive mechanism that drives the fins to open and close. problems arise

[0019] In addition, in Patent Document 4, not only the power for opening the flaps is consumed, but also it is necessary to delay the siren sound from the siren device until the flaps are fully opened.

Therefore, it may not be possible to transmit the siren sound with sufficient sound pressure to the outside of the vehicle in front of the vehicle at the desired timing

[0020] In addition, if the flaps are not opened due to a problem with the drive mechanism, it may not be possible to transmit the siren sound to the outside of the vehicle in front of the vehicle with sufficient sound pressure.
