Description

  The present invention relates to a vehicle body side structure that reduces a wind slob generated when a window opening that is opened and closed by raising and lowering a window glass is opened.

  Generally, a front side door and a rear side door are provided on the side of a vehicle body. For example, as disclosed in Patent Document 1, the rear side door is configured such that an opening surrounded by a window frame provided above a door main body is partitioned by a door partition sash in front and rear of a vehicle body, and a front rear window serving as one opening is formed. An opening and a rear partition opening are formed. The front rear window opening is opened and closed by a rising and lowering window glass, and a partition glass, which is a fixed window glass, is provided in the rear partition opening.

  In such a vehicle, when the vehicle travels within a predetermined speed range with the rear window opening opened, the traveling wind vibrates in the vehicle width direction behind the rear window opening, and the vibration of the air is used as an excitation source. Windslobes occur. That is, the separation vortex generated on the front end side of the rear window opening due to traveling moves rearward, and the frequency component due to pressure fluctuations generated by colliding with the door partition sash disposed at the rear end of the rear window opening has a rear component. Feedback is made to the front end side of the window opening, and a separation vortex of the same frequency is generated again. The cavity tone resulting from the pressure fluctuation at the specific frequency due to the feedback is coupled with the resonance frequency in the vehicle interior, so that the sound pressure level increases rapidly and wind slob is generated.

  There exists patent document 2 as an example of the apparatus which reduces this wind slob. This wind slob reducing device is provided with a deflector that is rotatable about an axis extending in the vertical direction on the vehicle front end side of the rear window opening that opens and closes by raising and lowering the window glass and on the inner side of the window glass. When the opening is opened, the deflector is displaced to the outside of the vehicle, so that the air flow that flows behind the vehicle body along the rear window opening is deflected to the outside of the vehicle compartment by the deflector, and the amount of air flow that hits the door partition sash is reduced. Reduce the wind slob by reducing it.

  Further, the wind slob reducing device of Patent Document 3 is provided with a blower provided with a blower and a duct inside the B pillar, and blows the wind sent from the blower out of the passenger compartment to the rear of the passenger compartment. The airflow flowing along the outside of the rear window opening is deflected when the window opening is opened, reducing the amount of air hitting the door partition sash at the rear end of the rear window opening and reducing the wind slob.
