[0023] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 1-5 As shown, the utility model provides a wave hub 1, including a rim 10 and a spoke 20 connecting a hub 30 and the rim 10. Preferably, the rim 10 and the spoke 20 are integrally formed and made of carbon fiber; further, the rim 10, the spoke 20 and the hub 30 are integrally formed. The rim 10 includes an outer ring tire mounting portion 11 for mounting a tire, an inner ring spoke connecting portion 12 for connecting the spokes, and two rim side walls 13 relatively arranged between the outer ring tire mounting portion 11 and the inner ring spoke connecting portion 12, wherein the outer ring tire mounting portion 11, the inner ring spoke connecting portion 12 and the two rim side walls 13 enclose a cavity. Preferably, the four are integrally formed and made of carbon fiber.

[0026] like Figure 1 , 4 As shown, the wheel rim 10 is provided with a plurality of wheel rim wave shapes 14, which extend from the inner ring spoke connection portion 12 to the two wheel rim side walls 13. Preferably, the wheel rim wave shapes 14 are symmetrically distributed with the center plane of the wheel rim 10 width as the symmetry plane. The wheel rim wave shapes 14 are gradually drawn along the wheel rim side walls 13 at an inclined angle and disappear near the brake edge of the wheel rim 10. The crest line and the trough line of the wheel rim wave shape 14 are arc lines. The wheel rim wave shape 14 can guide the flow direction of the airflow, reduce the wind resistance coefficient of the wheel rim 10, and have a better aerodynamic effect; and the waves on the side of the wheel rim 10 are equivalent to an arch, which increases the side deformation resistance, and the side rigidity of the wheel rim 10 is also improved.

[0027] Further, such as Figure 1 , 4 As shown, the inclination angle e of the wheel rim wave shape 14 relative to the inner ring tangent of the wheel rim 10 at its position is in the range of 20 degrees ≤ e ≤ 70 degrees. The rotation direction of the wheel rim is M, and the inclination angle of the wheel rim wave shape 14 can achieve a better effect of reducing wind resistance.

[0028] like Figure 1 , 3 As shown, the main body of the spoke 20 is in the shape of a flat shaft, and preferably, the cross section of the spoke 20 is in the shape of a water drop. Figure 3As shown, the spoke 20 includes a windward portion 21 located at the front end and facing the wind, a pointed tail portion 23, and two side surfaces 22 connected between the windward portion 21 and the tail portion 23. The flat shaft shape design of the spoke 20 can be used to greatly reduce the wind resistance of the vehicle, especially the flat shaft shape design with a teardrop-shaped cross section further reduces the wind resistance and has a better wind-breaking effect.

[0029] The spoke 20 is provided with a plurality of spoke wave shapes 24, which are perpendicular to the length direction of the spoke 20, so as to guide the airflow direction and reduce the wind resistance coefficient of the spoke 20. The spoke wave shape 24 extends from the windward portion 21 to the two side surfaces 22 and disappears at the tail portion 23. The spoke wave shape 24 can reduce the wind resistance of the spoke 20, thereby reducing the overall wind resistance of the wave hub 1.

[0030] Furthermore, the number of the 20 spokes is 2, 3, 4, 5, 6 or more; in this embodiment, the number of the 20 spokes is 5.

[0031] This embodiment also provides a wheel, comprising the wave hub 1 as described above.

[0032] This embodiment also provides a bicycle, comprising the wheel as described above, wherein one or both of the front and rear wheels are mounted with the wheel along the forward direction.

[0033] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
