The invention provides an inflation-free explosion-proof inner tube for a four-wheeler, and relates to the technical field of tires, the inflation-free explosion-proof inner tube for the four-wheeler comprises an annular tire body, the tire body comprises a first elastic structure, a second elastic structure and a third elastic structure, the second elastic structure is connected between the first elastic structure and the third elastic structure, and the third elastic structure is connected between the first elastic structure and the third elastic structure. The part, used for making contact with the inner surface of the outer tire, of the first elastic structure is of a regular hexagon or regular triangle or regular quadrilateral honeycomb structure, a first cavity structure is formed in the second elastic structure, and a plurality of columnar first supporting ribs are connected to the inner wall of the first cavity structure at intervals; one end of the first supporting rib is connected to the inner wall, close to the first elastic structure, of the first cavity structure, and the other end of the first supporting rib is connected to the inner wall, close to the third elastic structure, of the first cavity structure. Compared with an existing tire, the inflation-free explosion-proof inner tube for the four-wheeler has the advantages of being resistant to puncture, free of tire burst and good in slow inflation performance.

    本发明提供了一种四轮车用免充气防爆内胎,涉及轮胎技术领域,所述四轮车用免充气防爆内胎包括圆环形胎身,胎身包括第一弹性结构、第二弹性结构和第三弹性结构,第二弹性结构连接于第一弹性结构和第三弹性结构之间,且第一弹性结构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,第二弹性结构开设有第一空腔结构,且所述第一空腔结构的内壁间隔连接有多个呈柱状的第一支撑筋,所述第一支撑筋的一端连接于所述第一空腔结构靠近所述第一弹性结构方向的内壁,且另一端连接于所述第一空腔结构靠近所述第三弹性结构方向的内壁。本发明的四轮车用免充气防爆内胎相比于现有轮胎,具有不怕扎刺、不会爆胎、缓充性能好的优势。
