Description

Technical Field

[0001] This utility model relates to the field of bicycle rack technology, specifically to a bicycle rack with a spool. Background Technology

[0002] Over the past decade, the field of sports bicycle technology has experienced unprecedented rapid development, with significant changes in bicycle design and construction. These changes have presented new challenges to the compatibility and functionality of bicycle accessories. Particularly in the bicycle rack sector, existing rack products on the market are generally ill-suited for modern sports bicycles.

[0003] Firstly, from a materials application perspective, early bicycle frames were primarily made of aluminum alloy. Thanks to aluminum alloy's excellent machinability and relatively low cost, manufacturers could easily create mounting holes in the frame to accommodate various racks. However, with the gradual decrease in the cost of carbon fiber materials and their prominent lightweight and high-strength characteristics, modern sports bicycle frames have widely adopted carbon fiber. While carbon fiber frames possess superior performance, their unique material properties make it extremely difficult to pre-drill rack mounting holes in the frame. Furthermore, the slender structure of carbon fiber tubes cannot withstand the weight and pressure of traditional racks, thus limiting the possibility of installing racks on carbon fiber frames.

[0004] Secondly, the evolution of bicycle types has also brought new problems. In recent years, full-suspension mountain bikes have become widely popular due to their excellent shock absorption and handling. The frames of these bikes use a soft-connection design with shock absorption, which is fundamentally incompatible with the rigid connection between the fixed rear wheel end and the frame end used in traditional racks on the market. This makes it impossible to effectively install existing racks on full-suspension bikes.

[0005] Furthermore, the wheel diameter and tire width of mountain bikes have also increased significantly, gradually transitioning from the traditional 26-inch wheel diameter to 27.5-inch and even the current 29-inch wheel diameter, resulting in a situation where all three wheel diameters coexist in the market. This change directly affects the adaptability of rack installation, because the design of traditional racks did not take into account the diversity of wheel diameters, making it difficult to achieve stable and suitable installation on bicycles with different wheel diameters.

[0006] In summary, due to the combined effects of material innovation, changes in frame design, and the diversity of wheel diameters, traditional bicycle racks can no longer meet the installation requirements of modern sports bicycles. Against this backdrop, developing a bicycle rack that can overcome these challenges and is compatible with various types of modern sports bicycles is particularly important and urgent. Therefore, we propose a bicycle rack with a thru-axle. Utility Model Content

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. This utility model can achieve the connection between the connecting plate and the shelf fork by installing a fixed shaft.
