The embodiment of the invention provides a steering wheel and a motor vehicle, the steering wheel comprises a frame, a foaming body and a functional pad, the foaming body is integrally molded by placing the frame in a foaming mold, and a step part with a first surface profile and an accommodating groove with a second surface profile are formed on a rim; the radius of the first surface profile is larger than that of the second surface profile, the functional pad is arranged in the containing groove, at least part of the step part extends to the other side of the normal extension direction of the end of the containing groove adjacent to the step part to form an elastic part, a deformation gap is formed between the elastic part and the second surface profile, and the end of the functional pad is arranged in the deformation gap. The end portion of the functional pad extends into the gap between the elastic portion and the containing groove, when the elastic portion is pressed, the elastic portion and the functional pad deform synchronously, dents cannot be formed between the elastic portion and the functional pad, and the uneven hand feeling of the steering wheel can be improved. Even if the functional pad is pulled, the surface can still be kept flush with the first surface profile surface.

    本说明书实施例提供一种方向盘及机动车辆,方向盘包括框架、发泡体和功能垫,发泡体由框架置于发泡模具中一体模制成型,在轮辋上形成具有第一表面轮廓的台阶部和第二表面轮廓的容置槽,第一表面轮廓的半径大于第二表面轮廓的半径,功能垫设置在容置槽中,台阶部至少部分延伸到与之毗邻的容置槽的端部的法线延伸方向的另一侧形成弹性部,弹性部和第二表面轮廓之间形成形变间隙,功能垫的端部布置于形变间隙内。功能垫的端部伸入弹性部与容置槽之间的间隙中,当弹性部受到压力时与功能垫同步形变,不会在两者之间形成凹痕,可以改善方向盘凹凸不平的手感,同时在后续的拉伸包覆过程中,即使功能垫被拉扯也依然能保持表面与第一表面轮廓表面齐平。
