[0026] Referring to Figures 1-6 A spoke mounting reinforcing structure, comprising

[0027] A rim 1;

[0028] A hub body 2, spoke discs 3 arranged at both ends of the hub body 2, first and second protruding portions 30 and 32 evenly distributed around the spoke discs 3; first and second recesses 300 and 320 are formed between the first and second protruding portions 30 and 32 and the spoke discs 3, respectively, and the first and second recesses 300 and 320 are in abutment with the first and second inclined sections 500 and 510, respectively, so that the reinforcing member 5 is further fixed on the spoke discs 3.

[0029] Further, the first protruding part 30 and the second protruding part 32 are asymmetric structures, wherein the protruding height of the first protruding part 30 is H1, and the protruding height of the second protruding part 32 is H2, H1 < H2; the advantage of such arrangement is that it can increase the structural rigidity of the spoke disc 3, especially when subjected to greater loads or impacts, it helps to disperse and resist stress, thereby improving the overall structural strength and durability, at the same time, the asymmetric protruding design also helps to optimize the mechanical properties of the spoke disc 3 in a certain direction, such as improving its torsional performance, which is particularly important for bicycle wheels or other rotating parts, in addition, different protruding heights also affect the aerodynamic or hydrodynamic characteristics of the spoke disc 3, which helps to reduce resistance during rotation and improve efficiency, finally, different protruding heights are also used to adapt to different tension of spokes to ensure uniform tension of spokes on the rim, thereby improving the balance and stability of the wheel. In summary, such asymmetric and different height protruding design can improve the performance of the spoke disc 3 in many aspects, including structural strength, mechanical properties, dynamic characteristics, and the convenience of assembly and maintenance.

[0030] A plurality of spoke bodies 4 are connected corresponding to the first protruding part 30 and the second protruding part 32, and the other end of the spoke body 4 is connected with the rim 1; further, the spoke body 4 has a rod end, wherein the rod ends of two spoke bodies 4 arranged on the first protruding part 30 and the second protruding part 32 are stacked and cross-connected.

[0031] A reinforcing member 5 is arranged around the circumference of the spoke disc 3, and is placed between every two groups of first protruding part 30 and second protruding part 32 to enhance the stability and strength of the structure. Further, the reinforcing member 5 is made of carbon fiber material. The reinforcing member 5 includes but is not limited to carbon fiber material.

[0032] The reinforcing member 5 includes a first clamping part 50, a second clamping part 51 and a connecting part 52; wherein the first clamping part 50 includes a first inclined section 500, the second clamping part 51 includes a second inclined section 510, and the connecting part 52 includes a third inclined section 520, the first inclined section 500, the second inclined section 510 and the third inclined section 520 are combined to form a clamping end for clamping the spoke disc 3.

[0033] The first clamping part 50 is mainly used for fixing and supporting from one side of the spoke disc 3, ensuring that the reinforcing part 5 can be stably attached to the spoke disc 3, and the first inclined section 500 is designed to be inclined, which optimizes the force distribution, reduces stress concentration, and improves the stability and durability of the structure; the second clamping part 51 corresponds to the first clamping part 50 and is fixed and supported from the other side of the spoke disc 3, and cooperates with the first clamping part 50 to enhance the stability of the whole structure, and the second inclined section 510 is also designed to be inclined, which cooperates with the first inclined section 500 to bear the force and torque from the spoke disc, and the connecting part 52 serves as a bridge between the first clamping part 50 and the second clamping part 51, and the connecting part 52 not only plays a connecting role, but also enhances the stability and carrying capacity of the whole reinforcing part through its structural design, and the third inclined section 520 in the connecting part 52 optimizes the force path through the inclined design, reduces direct stress, and improves the overall performance of the structure.

[0034] Further, the first inclined section 500 and the second inclined section 510 in the clamping end are both formed at an angle A with the outer ring edge of the spoke disc 3, and 45°≤A≤60°. In one embodiment, in order to ensure the strength of the spoke disc 3, A is about 50 degrees. The advantage of this setting is that the contact area of the clamping end with the outer ring edge of the spoke disc 3 is relatively large, so that the clamping force is more evenly distributed, stress concentration is reduced, and the stability and durability of the structure are improved.

[0035] The above only describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
