The invention discloses a spare tire groove structure which comprises a first plane extending in the X direction and the Y direction, a groove body sunken downwards in the Z direction is formed in the first plane, the groove bottom is a second plane extending in the X direction and the Y direction, the second plane is in a composite shape, the front side in the X direction is semicircular, the rear side in the X direction is rectangular, and the groove side wall is a third curved surface extending in the Z direction. The third curved surface is connected with the first plane and the second plane at least on the two sides in the Y direction and the front side in the X direction, upwards-protruding reinforcing ribs are arranged on the second plane at least, and the reinforcing ribs at least comprise middle reinforcing ribs; the middle reinforcing ribs are in an H shape, two longitudinal convex ribs of the H shape extend in the Y direction, and one transverse convex rib extends in the X direction. The spare tire groove structure has the beneficial effects that a scheme which is simple to design and manufacture and light in weight is provided, the local mode of the spare tire groove is improved, and the problem of resonance of the spare tire groove in the running process of an automobile is avoided.
本发明公开了一种备胎槽结构,包括沿X向和Y向延伸的第一平面,第一平面上设有向Z向下方凹陷的槽体,槽底为沿X向和Y向延伸的第二平面,第二平面的形状复合形状,X向的前侧为半圆形,后侧为矩形,槽侧壁为沿Z向延伸的第三曲面,第三曲面至少在Y向两侧和X向前侧与第一平面和第二平面连接,至少在第二平面上设有上凸的加强筋,加强筋至少包括中部加强筋;中部加强筋的形状为“H”形,“H”形的两条纵向凸筋沿Y向延伸,一条横向凸筋沿X向延伸。本发明的有益效果是:提供了设计制造简单且兼顾轻量化的方案,提高备胎槽的局部模态,避免汽车在行驶过程中出现备胎槽共振问题。
