Description

Technical Field

[0001] This utility model belongs to the field of bicycle parts, specifically, it relates to a new type of high-strength spoke. Background Technology

[0002] In recent years, as cycling has become more competitive and multifunctional, traditional spokes have gradually revealed the following technical bottlenecks under extreme conditions: Existing bicycles use a single carbon fiber reinforced structure, which achieves lightweighting, but is prone to interlaminar delamination failure under impact loads. Experimental data shows that its lateral impact strength is less than 20 kJ / m², making it difficult to meet the requirements of complex road conditions such as mountain bikes. Utility Model Content

[0003] In view of this, the technical problem to be solved by this utility model is to provide a new type of high-strength spoke that can quickly absorb impact energy when subjected to external impact through the special pore structure of the titanium alloy honeycomb layer; and to improve the resistance to lateral bending by setting figure-eight reinforcing strips in the carbon fiber braided layer to form a closed stress ring, thereby enhancing the overall strength and compressive strength of the spoke.

[0004] To solve the above-mentioned technical problems, this utility model discloses a novel high-strength spoke, comprising: a pressure-resistant core layer, a titanium alloy honeycomb layer on the outside of the pressure-resistant core layer, a carbon fiber braided layer on the outside of the titanium alloy honeycomb layer, and transversely tightly arranged figure-eight reinforcing strips inside the carbon fiber braided layer; a nano-ceramic transition layer on the outside of the carbon fiber braided layer, and a rigid protective layer on the outside of the nano-ceramic transition layer.

[0005] According to one embodiment of the present invention, the height of the above-mentioned pressure-resistant core layer is 30%-40% of the total height.

[0006] According to one embodiment of the present invention, the porosity of the titanium alloy honeycomb layer is between 30% and 50%.

[0007] According to one embodiment of the present invention, the thickness of the above-mentioned rigid protective layer is 5-8 μm.

[0008] Compared with the prior art, the present invention can achieve the following technical effects:

[0009] 1) The special porous structure of the titanium alloy honeycomb layer can quickly absorb impact energy when subjected to external impact; by setting figure-eight reinforcing strips in the carbon fiber braided layer to form a closed stress ring, the resistance to lateral bending is improved, and the overall strength and compressive strength of the spokes are enhanced.

[0010] Of course, any product implementing this utility model does not necessarily need to achieve all of the above technical effects at the same time. Attached Figure Description

[0015] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0016] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a novel high-strength spoke according to an embodiment of the present invention. As shown in the figure, a novel high-strength spoke includes: a pressure-resistant core layer 10, a titanium alloy honeycomb layer 20 on the outside of the pressure-resistant core layer 10, a carbon fiber braided layer 30 on the outside of the titanium alloy honeycomb layer 20, and transversely tightly arranged figure-eight shaped reinforcing strips 40 inside the carbon fiber braided layer 30; a nano-ceramic transition layer 50 on the outside of the carbon fiber braided layer 30, and a rigid protective layer 60 on the outside of the nano-ceramic transition layer 50.

[0017] In one embodiment of this utility model, a pressure-resistant core layer 10 is provided, the height of which is 30%-40% of the total height, thereby enhancing the overall strength of the spokes. A titanium alloy honeycomb layer 20 is provided on the outside of the pressure-resistant core layer 10. The porosity of the titanium alloy honeycomb layer 20 is between 30% and 50%. This porosity achieves both lightweight design and allows the titanium alloy honeycomb layer 20 to undergo controllable deformation under external impact, absorbing impact energy.

[0018] Furthermore, a carbon fiber braided layer 30 is provided on the outside of the titanium alloy honeycomb layer 20, and a transversely closely arranged figure-eight reinforcing strip 40 is provided in the carbon fiber braided layer 30. The figure-eight reinforcing strip 40 forms a closed stress ring, which improves the resistance to lateral bending and increases the strength.

[0019] Preferably, a nano-ceramic transition layer 50 is provided on the outside of the carbon fiber braided layer 30, so that the spoke strength gradually increases from the outside to the inside. Finally, a hard protective layer 60 is provided on the outside of the nano-ceramic transition layer 50. The thickness of the hard protective layer 60 is 5-8μm, which is used to protect the spokes.

[0020] In summary, this invention utilizes the unique porous structure of the titanium alloy honeycomb layer 20 to rapidly absorb impact energy when subjected to external impacts; and by setting figure-eight reinforcing strips 4040 within the carbon fiber braided layer 30 to form a closed stress ring, it enhances the resistance to lateral bending, thereby strengthening the overall strength and compressive strength of the spokes.
