Integrated upper pipe wrapping structure of bicycle and integrated frame

The utility model provides an integrated upper pipe wrapping structure of a bicycle and an integrated frame, and belongs to the technical field of bicycles. The integrated frame mainly comprises an integrated upper pipe wrapping structure and an integrated lower pipe wrapping structure, inner frames are designed at the front ends of an upper pipe and a lower pipe, the two inner frames are welded through hydraulic integrated forming, and a head pipe is embedded and fixed in the inner frames. Through the structural design that the upper pipe and the lower pipe wrap the pipe, the density and the strength of the head assembly can be improved, welding beads do not appear on the two sides of the head pipe end, front-end wiring is conducted, and the attractiveness is improved; moreover, by changing the length of the head tube and the large bending angle of the upper tube, the integrated frame structure can be suitable for various models. 本实用新型提出了一种自行车的一体式上管包管结构及一体式车架，属于自行车技术领域。本一体式车架主要包括一体式上管包管结构和一体式下管包管结构，通过在上管和下管的
