The invention relates to a vehicle comprising a body structure with a noise-proof seal. The vehicle body structure includes: an outer panel; the C-column inner plate is connected to the inner side of the outer plate, a vehicle body cavity is defined by the C-column inner plate and the outer plate, and the C-column inner plate is provided with a mounting opening suitable for mounting an environment part; the wheel cover inner plate is connected to the bottom of the C column inner plate and connected to the inner side of the outer plate; the noise-proof sealing part is adjacent to the bottom of the C column inner plate, extends in the vehicle body cavity in the longitudinal direction, and is tightly clamped between the outer plate and the C column inner plate; the anti-noise seal includes a sealing foam disposed outside the mounting opening and at least one expansion sheet disposed forward and/or rearward of the sealing foam. According to the vehicle, wheel noise can be prevented from being transmitted from the vehicle body side rear area to the interior of the compartment in an economical mode, and therefore the NVH performance of the vehicle is effectively improved.

    本发明涉及一种包括带有防噪声密封件的车身结构的车辆。该车身结构包括:外板;C柱内板,其连接至外板的内侧,并与外板限界出车身空腔,其中,该C柱内板设置有适于安装环境件的安装开口;轮罩内板,其连接至C柱内板的底部,并连接至外板的内侧;以及防噪声密封件,其邻近于C柱内板的底部在该车身空腔中沿所述纵向方向延伸,并紧密夹置于外板与C柱内板之间,其中,该防噪声密封件包括布置于该安装开口的外侧的密封泡棉以及布置于该密封泡棉的前方和/或后方的至少一个膨胀片。根据本发明的车辆能够以经济的方式阻止车轮噪声从车身侧后部区域向车厢内部传递,因此有效地改善了车辆的NVH性能。
