The embodiment of the invention discloses a vehicle door inner plate, a vehicle door and a vehicle. The vehicle door inner plate comprises a connecting part, a transition part and a side wall; the connecting part is connected with the bottom of the vehicle door outer plate, the transition part is formed by extending from the connecting part to the side away from the vehicle door outer plate, and the side wall is formed by extending from the transition part upwards in the direction away from the vehicle door outer plate; and the transition part is provided with a first water leakage hole, and the lower part of the side wall is provided with a second water leakage hole. According to the vehicle door inner plate, the vehicle door and the vehicle, the first water leakage hole and the second water leakage hole are formed in the transition part and the lower portion of the side wall respectively, the number of the holes is increased, the single area of the holes is reduced, high-frequency noise is reduced to medium frequency, and the NVH performance is improved.

    本公开实施例公开了一种车门内板、车门及车辆,车门内板包括连接部、过渡部和侧壁,所述连接部与车门外板的底部连接,所述过渡部由所述连接部向远离所述车门外板的一侧延伸形成,所述侧壁由所述过渡部向上且远离所述车门外板的方向延伸形成;其中,所述过渡部设置有第一漏水孔,所述侧壁下部设置有第二漏水孔。基于本公开上述实施例提供的车门内板、车门及车辆,通过在过渡部和侧壁下部分别设置第一漏水孔和第二漏水孔,增多开孔数,使得开孔的单体面积减小,使高频噪声降低成中频,提升NVH性能。
