Problems solved by technology

[0004] However, according to the structure disclosed in Japanese Patent Application Laid-Open No. 2003-72396, since the running wind passing through the radiator grille is changed in direction and enters the air intake port, depending on the weight of the foreign matter mixed in the running wind, different, there is a possibility that the foreign matter enters the air intake together with the direction-changed driving wind
Therefore, the above-mentioned disclosure also has room for improvement on this point

[0039] Below, use Figure 1 to Figure 5 One embodiment of the air intake structure at the front of the vehicle according to the present invention will be described. In addition, arrow FR shown in these drawings indicates the front side in the vehicle front-rear direction, arrow OUT indicates the vehicle width direction outer side, and arrow UP indicates the upper side in the vehicle vertical direction.

[0040] Such as figure 1 As shown, the vehicle front of vehicle 10 is configured to include radiator grille 12 , engine hood / bonnet 14 , radiator 16 , radiator bracket 18 , radiator bracket cover 20 , and intake duct 22 .

[0041] The radiator grill 12 is arranged between a front bumper 24 and a hood 14 which will be described later. In addition, a plurality of grill fins 26 extending in the vehicle width direction are provided on the radiator grill 12 so as to be spaced apart substantially in the vehicle vertical direction. Accordingly, vents 28 communicating in the vehicle...

Abstract

An air intake structure at the front of a vehicle, comprising: a radiator grille disposed on the vehicle front side of a radiator bracket; an engine hood inner panel disposed on the vehicle upper side of the radiator bracket and the radiator grille the radiator bracket cover, which is arranged between the upper end of the radiator bracket and the inner panel of the engine hood, and is formed in a substantially plate shape, the radiator bracket cover has the function of allowing the airflow from the radiator grille to flow to the radiator bracket The cover vent part that flows between the cover and the hood inner panel, and the air guide port that introduces the air flow to the vehicle rear side; the air intake duct that is provided on the vehicle rear side of the radiator bracket For engine introduction, a plurality of upper side bars extending in the front-rear direction of the vehicle and arranged alternately with slits in the vehicle width direction are provided at the cover ventilation part of the radiator bracket cover, and a plurality of slits are arranged in the slits. The lower side rail part extends on the lower side of the vehicle and extends in the front-rear direction of the vehicle.

Description

technical field [0001] The invention relates to an air intake structure at the front of a vehicle. Background technique [0002] Japanese Patent Application Laid-Open No. 2003-72396 discloses an air intake structure at the front of a vehicle. Specifically, it has an engine intake duct disposed on the vehicle upper side of a radiator in an engine room, and a radiator grill disposed on the vehicle front side of the engine intake duct. The intake port of the intake duct for the engine is arranged toward the radiator grill side at a position offset leftward from the center in the vehicle width direction. In addition, in the radiator grill, only a portion corresponding to the intake port of the intake duct for the engine is blocked. [0003] That is, the traveling wind enters the engine compartment through a portion other than the blocked portion of the radiator grill. Therefore, the running wind passing through the radiator grille does not directly enter the air intake, but e...
