Technical Field

[0001] The invention relates to the technical field of bicycle accessories, and in particular to a bicycle wheel rim structure. Background Art

[0002] At present, bicycle wheel rims are mainly spoke-type wheels 90, such as Fig.10 As shown, the combination of the rim 91, the hub 92 and the spokes 93 of the spoke-type wheel leads to complicated processing and high cost. There are a large number of spokes arranged radially. If one of them is damaged, the structure will be unbalanced and unstable. In addition, when the bicycle falls, the spokes are inserted into the parking posts of other bicycles, making it difficult to lift it up, posing a safety hazard. Therefore, the knife-wheel type wheel came into being. However, the existing knife-wheel type wheel is completely bilaterally symmetrical, has a relatively simple structure and poor balance, is relatively heavy, and increases the burden of long-term cycling.

[0003] Therefore, how to provide a bicycle rim structure with a stable structure, light overall weight and high stability is a problem that needs to be solved urgently by those skilled in the art. Summary of the invention
