The invention provides an inflation-free explosion-proof inner tube for a light vehicle, and relates to the technical field of tires, the inflation-free explosion-proof inner tube for the light vehicle comprises an annular tire body, the tire body comprises a first-stage elastic deformation part, a second-stage elastic deformation part and a third-stage elastic deformation part, the second-stage elastic deformation part is connected between the first-stage elastic deformation part and the third-stage elastic deformation part, the part, used for making contact with the inner surface of the outer tire, of the first-stage elastic deformation part is of a regular hexagon or regular triangle or regular quadrangle honeycomb structure, and the second-stage elastic deformation part is provided with an annular cavity structure. The inner wall of the cavity structure is connected with a first supporting rib structure, one side of the first supporting rib structure is connected to the inner wall, close to the first-stage elastic deformation part, of the cavity structure, and the other side of the first supporting rib structure is connected to the inner wall, close to the third-stage elastic deformation part, of the cavity structure. Compared with an existing solid tire, the inflation-free explosion-proof inner tube for the light vehicle has the advantages of being good in slow inflation performance and safer and more stable in running.

    本发明提供了一种轻型车用免充气防爆内胎,涉及轮胎技术领域,所述轻型车用免充气防爆内胎包括一圆环形胎体,胎体包括一级弹性变形部、二级弹性变形部和三级弹性变形部,二级弹性变形部连接于一级弹性变形部与三级弹性变形部之间,且一级弹性变形部用于与外胎内表面接触的部分为正六边形或正三角形或正四边形的蜂窝状结构,二级弹性变形部开设有呈环形的空腔结构,且空腔结构的内壁连接有第一支撑筋结构,第一支撑筋结构的一侧连接于空腔结构靠近一级弹性变形部方向的内壁,且另一侧连接于空腔结构靠近三级弹性变形部方向的内壁。本发明的轻型车用免充气防爆内胎相比于现有实心轮胎,具有缓充性能好、行驶更安全更平稳的优势。
