[0033] The present utility model will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0034] Embodiment 1

[0035] As shown in Figures 1-7 , this embodiment provides an integrated spoke 10, which includes a middle part 101 and two arm parts 102 respectively connected to both ends of the middle part 101. The ends of the two arm parts 102 of the spoke 10 are used to be connected to the rim 20; the middle part 101 of the spoke 10 is used to be connected to the hub 30. As shown in Figure 1 and Figure 2 , the two arm parts 102 of multiple spokes 10 are connected to the rim 20, and the middle parts 101 of multiple spokes 10 are connected to the hub 30. A side cover 40 is installed on the outer side of the hub 30. Thus, the spoke 10, the hub 30 and the side cover 40 are assembled into a whole to form a complete wheel. For example, the side cover 40 is connected to the outer side of the hub 30 by gluing.

[0036] The middle part 101 of the spoke 10 is in the shape of a flat shaft, and the arm part 102 is generally in the shape of a flat shaft. The end of the arm part 102 transitions from the flat shaft shape to the cylindrical shape, so as to facilitate connection with the rim 20 through a connecting piece. The spoke 10 in the shape of a flat shaft has a wind-breaking effect and can better reduce the wind resistance of the spoke 10. The spoke 10 is a fiber spoke, and the fiber spoke is formed by bundling multiple fibers made of a high-strength and high-modulus material and then cured by a strong resin. Preferably, the spoke 10 is a carbon fiber spoke.

[0037] It should be noted that this embodiment is described by taking the spoke 10 made of carbon fiber material as an example. However, it can be expected by those skilled in the art that it is also a feasible solution to use spokes made of other high-strength and high-modulus fiber materials. Among them, high-strength and high-modulus fibers refer to high-performance fiber materials defined under well-known standards in the industry, specifically referring to synthetic fibers or natural fibers with a strength greater than 10 CN / dtex and a modulus greater than 200 CN / dtex.

[0038] Refer to Figures 2-5 , the hub 30 includes a hub body 31 and flanges 32. There is one flange 32 provided at each end of the hub body 31. A plurality of card slots 321 are provided on each flange 32. The number of card slots 321 corresponds to the number of spokes 10, and the shape of the card slots 321 is adapted to the outer shape of the middle part 101 of the spoke 10, so that the spoke 10 can be embedded in the card slot 321 through the middle part 101. In this embodiment, there are 5 card slots 321 provided on each flange 32. The side cover 40 is connected and installed on the flange 32.

[0039] Refer to Figures 4-7 , for the convenience of installation and positioning, a first positioning structure is provided on the middle part 101 of the spoke 10, and a second positioning structure matching the first positioning structure is provided in the card slot 321 of the flange 32. The first positioning structure and the second positioning structure can be a mutually cooperating clamping structure. For example, in this embodiment, the first positioning structure and the second positioning structure can be a convex column and a positioning hole structure that cooperate with each other. Specifically, the first positioning structure is a positioning hole 104, and the second positioning structure is a positioning convex column 323. The positioning convex column 42 is clamped and positioned with the positioning groove 24, so as to realize the installation and positioning of the spoke 10 and the flange 32.

[0040] In this embodiment, the spoke 10 is embedded in the card slot 321 of the hub 30, so that the force between the spoke 10 and the hub 30 changes from the traditional point force to surface force, improving the connection strength; the spoke 10 and the hub 30 are not connected by metal parts, and the spoke 10 does not need to be connected to the hub 30 by gluing. The spoke assembly is convenient and easy to replace; the manufacture of the spoke 10 does not require a secondary forming process, and the manufacturing process is simple; the integral spoke 10 has high rigidity, and after multiple spokes 10 are assembled, the overall rigidity of the wheel set is improved.

[0041] Of course, in some other embodiments, the spoke 10 can be connected to the hub 30 by gluing, thereby enhancing the connection strength between the spoke 10 and the hub 30.

[0042] Referring to Figures 5-7 , in this embodiment, the positioning boss 42 is a columnar structure with an elliptical cross-section, and the positioning hole 104 is an elliptical hole; however, it is not limited thereto. The positioning boss 42 can also be a columnar structure with a circular or regular polygonal cross-section, etc., and the positioning hole 104 can also be a circular hole or a regular polygonal hole. In this embodiment, the positioning boss 42 is a columnar structure with an elliptical cross-section, and the positioning hole 104 is an elliptical hole, with smoother edges and less stress generated by the spoke 10.

[0043] However, in this embodiment, the positioning hole 104 is provided on the middle portion 101 of the spoke 10, which may have an impact on the strength of the middle portion 101 of the spoke 10. Therefore, in this embodiment, a widened convex portion 105 is further provided on the middle portion 101 of the spoke 10. The widened convex portion 105 extends outwardly from the side of the middle portion 101, and the position of the widened convex portion 105 on the middle portion 101 corresponds to the positioning hole 104. A widened groove 324 that cooperates with the widened convex portion 105 is provided on the card slot 321. The widened convex portion 105 and the widened groove 324 are installed and matched, thereby enhancing the installation connection and positioning between the spoke 10 and the flange 32. And the widened convex portion 105 corresponds to the positioning hole 104, which also enhances the strength of the spoke at the positioning hole 104 and reduces the impact on the strength of the spoke 10 caused by the provision of the positioning hole 104 on the middle portion 101 of the spoke 10.

[0044] A thickened convex portion 103 is further provided on the middle portion 101 of the spoke 10. The thickened convex portion 103 extends downward from the lower surface of the middle portion 101, and the position of the thickened convex portion 103 on the middle portion 101 corresponds to the positioning hole 104. A deepened groove 322 that cooperates with the thickened convex portion 103 is provided on the card slot 321. The thickened convex portion 103 and the deepened groove 322 are installed and matched, thereby further enhancing the installation connection and positioning between the spoke 10 and the flange 32. And the thickened convex portion 103 corresponds to the positioning hole 104, which also further enhances the strength of the spoke at the positioning hole 104 and further reduces the impact on the strength of the spoke 10 caused by the provision of the positioning hole 104 on the middle portion 101 of the spoke 10.

[0045] The thickened convex portion 103 also thickens the area of the widened convex portion 105, thereby forming an integral widened and thickened structure for the middle portion 101 of the spoke 10. The widened groove 324 and the deepened groove 322 also form an integral body. Therefore, the widening and thickening effects on the middle portion 101 of the spoke 10 are enhanced, and the installation connection and positioning effects between the spoke 10 and the flange 32 are enhanced.

[0046] Reference Figures 4-5 As shown in Figures 4-5 , the spoke 10 bypasses the hub 30 at a small angle. That is, compared with the straight state where the two arm portions 102 of the spoke 10 are opposite to each other and on the same straight line, one of the two arm portions 102 forms a bending process angle A with respect to the other arm portion, and the angle A is a small angle. For example, the angle A is not greater than 5°. Thus, the spoke 10 provides a centripetal force towards the center of the hub 30 after installation; after multiple spokes 10 are installed on the hub 30, the multiple centripetal forces cancel each other out, thereby providing a stable installation of the spoke 10 on the hub 30.

In this embodiment, the bending process angle A1 of one of the two arm portions 102 of the spoke 10 with respect to the other arm portion is approximately a right angle. For example, the angle A1 is 98°. Thus, the spoke 10 provides a centripetal force towards the center of the hub 30 after installation; after multiple spokes 10 are installed on the hub 30, the multiple centripetal forces cancel each other out, thereby providing a stable installation of the spoke 10 on the hub 30.

In this embodiment, the bending process angle A2 of one of the two arm portions 102 of the spoke 10 with respect to the other arm portion is an obtuse angle. For example, the angle A2 is 155°. Thus, the spoke 10 provides a centripetal force towards the center of the hub 30 after installation; after multiple spokes 10 are installed on the hub 30, the multiple centripetal forces cancel each other out, thereby providing a stable installation of the spoke 10 on the hub 30.

For example, the angle A3 is 226°. Thus, the spoke 10 provides a centripetal force towards the center of the hub 30 after installation; after multiple spokes 10 are installed on the hub 30, the multiple centripetal forces cancel each other out, thereby providing a stable installation of the spoke 10 on the hub 30.
