The invention provides a tire body structure and a non-pneumatic tire. The tire body structure comprises a head part and a neck part, the neck part is arranged on the inner circumferential surface ofthe head part and protrudes towards the radial inner side of the tire, and the inner circumferential surface of the head part, the side surface of the neck part and the inner circumferential surface of the neck part jointly define a matching part matched with a rim; a plurality of radial center holes and a plurality of radial side holes are evenly distributed in the inner circumferential face of the neck part at intervals along the whole circumference of the tire, the radial center holes are located in the axial center of the inner circumferential face of the neck part, and the radial side holes are symmetrically formed in the two sides of the radial center holes and distributed alternately with the radial center holes in the circumferential direction of the tire, the radial center holes and the radial side holes are perpendicular to the inner circumferential face of the neck part and extend towards the radial outer side of the tire; a plurality of axial holes are formed in the side surface of the head part and are communicated with the radial central holes in a one-to-one correspondence manner; the phenomenon of ring slipping between the tire and a rim can be avoided, it is ensured that the tire has good buffer performance and durability, and the endurance mileage of a vehicle is increased.

    本发明提出了一种轮胎胎体结构及免充气轮胎,该胎体包括头部和颈部,颈部设在头部内周面上并向轮胎径向内侧凸出,头部内周面、颈部侧面和颈部内周面共同限定出与轮辋配合的配合部;颈部内周面具有沿轮胎全圆周均匀间隔分布的若干径向中心孔和若干径向边孔,若干径向中心孔位于颈部内周面的轴向中心位置,若干径向边孔对称布置在若干径向中心孔的两侧且在轮胎周向上与若干径向中心孔交替分布,径向中心孔和径向边孔均垂直于颈部内周面向轮胎径向外侧延伸;头部侧面具有若干轴向孔,若干轴向孔与若干径向中心孔一一对应地相贯通;可避免轮胎与轮辋发生滑圈的现象,确保轮胎具有良好的缓冲性能和耐久性能,提升车辆的续航里程。
