A tire rim structure including an annular inner ring (2) provided on the inner ring of a tire body (1) and a circular outer ring (3) provided on the outside of the tire body (1), fixedly connected to the annular inner ring (2), and formed by stamping. The annular inner ring (2) includes an annular inner ring body (21) formed by extrusion, an annular left ring (22) provided at one side of the annular inner ring body (21) and formed by extrusion, and an annular right ring (23) provided at the other side of the annular inner ring body (21), connected to the circular outer ring (3), and formed by extrusion. A shaft hole (31) is provided at the middle part of the circular outer ring (3). By breaking down a tire rim into the annular inner ring body (21), the left ring (22), the right ring (23), and the outer ring (3) connected to the right ring, each of the components composing the tire rim can be processed and formed via extrusion or stamping processes, this provides increased consistency compared with an existing tire rim that is integrally processed and formed via a casting process, thus allowing for increased structural strength and simplified manufacturing process. |
