Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power-assisted bicycles, in particular to a belt hook of a park power-assisted bicycle. Background Art
[0002] As the key medium between the frame and the wheelset, the bicycle dropout bears the interaction force between the transmission and the frame. Its original design was to achieve a stable connection between the frame and the wheelset to ensure the normal running of the bicycle. However, in actual use, the problem of the dropout being prone to deformation gradually emerged, becoming a technical problem that needs to be solved urgently in the bicycle field.
[0003] There are two main reasons why the dropout is prone to deformation. On the one hand, the dropout is subject to a huge force between the derailleur and the frame. During riding, especially on rough roads, this force will be further increased, causing the dropout to deform easily. On the other hand, the material and structure of the dropout itself are also important factors affecting its ability to resist deformation. Traditional dropouts are mostly made of metal, which has certain strength and toughness, but is still prone to deformation under long-term high loads.
[0004] Deformation of the dropout not only affects the stability of the bicycle, but also poses a potential threat to the safety of the rider. Once the dropout is deformed, its connection with the frame and wheels becomes unstable, which may cause the derailleur to fail or damage the frame. In emergency situations, such as when falling, the deformed dropout may also aggravate the collision between the derailleur and the ground, resulting in more serious consequences. Utility Model Content
[0005] In view of the problems existing in the above-mentioned background technology, the utility model provides a belt hook for a park power-assisted bicycle, which solves the problem that the hook mouth of the existing bicycle is easily deformed due to uneven force.
