Abstract

This invention provides a spoke-based wind resistance reduction structure, comprising a head, a neck, a middle section, and a threaded connection. The neck is integrally connected to the bottom surface of the head, and the cross-section of the neck is smaller than that of the head. The middle section is integrally connected to the bottom surface of the neck, and includes a first plane and a second plane, which flatten the middle section, and its cross-section is smaller than that of the neck. The threaded connection is integrally connected to the bottom surface of the middle section, and its cross-section is smaller than that of the threaded connection. This allows the spoke-based wind resistance reduction structure to be installed between the hub and the rim. The flat, streamlined middle section, combined with a short spoke cap, ensures that its exposed length is lower than or equal to the rim surface. Furthermore, the first and second planes of the middle section enable the flat, streamlined middle section to achieve the effect of minimizing wind resistance.

Description

Technical Field

[0001] This utility model relates to an improvement of the spoke structure for reducing wind resistance, and more particularly to a spoke design that can achieve the lowest possible wind resistance. Background Technology

[0002] The wind resistance caused by bicycle wheelsets mainly comes from two sources: the numerous spokes and the spoke caps exposed on the rim.

[0003] However, the spokes currently available on the market for bicycles are limited by the manufacturing process, which means that the spokes cannot fully and effectively conform to aerodynamics, resulting in limited effectiveness in reducing wind resistance. Utility Model Content

[0004] The main purpose of this utility model is to provide a spoke structure that reduces wind resistance, in which a flat, streamlined middle section is fully installed between the hub and the rim, and a short spoke cap is used in conjunction with the flat, streamlined middle section so that the exposed length is lower than or equal to the surface of the rim, thereby achieving the effect of minimizing wind resistance.

[0005] To achieve the above objectives, this utility model provides a spoke-based wind resistance reduction structure, comprising: a head, a neck, a middle section, and a threaded connection. The neck is integrally connected to the bottom surface of the head, and the cross-section of the neck is smaller than that of the head. The middle section is integrally connected to the bottom surface of the neck, and the middle section includes a first plane and a second plane, which flatten the middle section, and the cross-section of the middle section is smaller than that of the neck. The threaded connection is integrally connected to the bottom surface of the middle section, and the cross-section of the middle section is smaller than that of the threaded connection.

[0006] In one embodiment of the above-mentioned spoke-reducing wind resistance structure, the length of the head is 1.3mm to 1.7mm, preferably 1.5mm.

[0007] In one embodiment of the above-mentioned spoke-reducing wind resistance structure, the outer periphery of the neck is provided with a plurality of cross-sections, making the neck a polygonal prism.

[0008] In one embodiment of the aforementioned spoke-reducing wind resistance structure, the neck is bent.

[0009] In one embodiment of the above-mentioned spoke-reducing wind resistance structure, the length of the middle section is 220mm to 290mm, preferably 260mm.

[0010] In one embodiment of the above-mentioned spoke-reducing wind resistance structure, a first connecting section is provided between the middle section and the neck, the length of the neck is 4mm to 6mm, preferably 5mm; the total length of the neck and the first connecting section is 5mm to 10mm, preferably 6mm.

[0011] In one embodiment of the above-mentioned spoke-reducing wind resistance structure, a second connecting section is provided between the middle section and the threaded section, the length of the threaded section is 8mm to 10mm, preferably 9mm; the total length of the threaded section and the second connecting section is 10mm to 15mm, preferably 10mm.

[0012] This utility model's spoke-reducing wind resistance structure effectively improves upon the shortcomings of conventional technology. It can be installed between the hub and the rim, and by combining a flat, streamlined middle section with a short spoke cap, the exposed length of which is lower than or equal to the rim surface. Furthermore, by utilizing the first and second planes of the middle section, the flat, streamlined middle section achieves the effect of minimizing wind resistance. Attached Figure Description

[0018] Please see Figures 1 to 3 The figures shown are side views of the present invention. Figure 1 A side view of the present invention. Figure 2 And a schematic diagram of the usage state of this utility model. As shown in the figure: This utility model provides a spoke-reducing wind resistance structure, which includes at least a head 1, a neck 2, a middle section 3, and a screw connection 4.

[0019] The neck 2 is integrally connected to the bottom surface of the head 1, and the cross-section of the neck 2 is smaller than that of the head 1.

[0020] The middle section 3 is integrally connected to the bottom surface of the neck 2. The middle section 3 includes a first plane 31 and a second plane 32. The first plane 31 and the second plane 32 make the middle section 3 flat, and the cross section of the middle section 3 is smaller than the cross section of the neck 2.

[0021] The threaded part 4 is integrally connected to the bottom surface of the middle section 3, and the cross-section of the middle section 3 is smaller than the cross-section of the threaded part 4.

[0022] In this embodiment, the spoke wind resistance reduction structure of this utility model is mainly formed by straight drawing. When in use, the head 1 and the neck 2 are assembled to the hub 5 of the rim 7, and the screw part 4 is used to assemble the required spoke cap 6 to the rim 7. Thus, the spoke wind resistance reduction structure of this utility model can be completely installed between the hub 5 and the rim 7. By using the first plane 31 and the second plane 32, the flat and streamlined middle section 3 can achieve the effect of reducing wind resistance to the minimum.

[0023] In one embodiment of the present invention, the difference from the above embodiment is that the length of the head 1 is 1.3mm to 1.7mm, preferably 1.5mm.

[0024] In one embodiment of the present invention, the difference from the above embodiment is that the length of the middle section 3 is 220mm to 290mm, preferably 260mm.

[0025] In one embodiment of the present invention, the difference from the above embodiment is that a first connecting segment 21 is provided between the middle section 3 and the neck 2, the length of the neck 2 is 4mm to 6mm, preferably 5mm; the total length of the neck 2 and the first connecting segment 21 is 5mm to 10mm, preferably 6mm.

[0026] In one embodiment of the present invention, the difference from the above embodiment is that a second connecting section 41 is provided between the middle section 3 and the threaded section 4, the length of the threaded section 4 is 8mm to 10mm, preferably 9mm; the total length of the threaded section 4 and the second connecting section 41 is 10mm to 15mm, preferably 10mm.

[0027] Based on the above embodiments, after deducting the length of the head 1, neck 2, and screw connection 4 from the total length of the spoke wind resistance reduction structure of this utility model, the length of the middle section 3 can be close to 100% of the total length of the spoke wind resistance reduction structure of this utility model. This allows the middle section 3 to have a maximized length design in the spoke wind resistance reduction structure of this utility model, so that the spoke wind resistance reduction structure of this utility model can be completely installed between the hub 5 and the rim 7. By utilizing the first plane 31 and the second plane 32, the flat and streamlined middle section 3 can be combined with a short spoke cap 6, so that its exposed length is lower than or equal to the surface of the rim 7, thereby achieving the effect of minimizing wind resistance.

[0028] In addition, the first connecting section 21 and the second connecting section 41 can also serve as auxiliary reinforcing structures for connecting the neck 2 and the screwed part 4 to the middle section 3, respectively, so as to maintain the overall rigidity of the spoke wind resistance reduction structure of the present invention and prevent the spoke wind resistance reduction structure of the present invention from having strength problems due to the flat and streamlined middle section 3.

[0029] In one embodiment of this utility model, the difference from the above embodiment is that the outer periphery of the neck 2 is provided with a plurality of cut surfaces 22, making the neck 2 a polygonal prism. In this way, when the head 1 and the neck 2 are assembled to the hub 5, the cut surfaces 22 can be used to securely assemble the neck 2 to the joint of the hub 5 without causing damage to the hub 5.

[0030] Please see Figure 4 The diagram shown is a side view of another embodiment of the present invention. In this embodiment, the difference from the above embodiment is that the neck 2 can be bent according to the actual application requirements, so that the spoke wind resistance reduction structure of the present invention can be applied to different types of hubs 5 and can meet the actual application requirements.

[0031] In summary, the spoke-reducing wind resistance structure of this utility model effectively improves upon the shortcomings of conventional technology. It can be installed between the hub and the rim, and by combining a flat, streamlined middle section with a short spoke cap, the exposed length of which is lower than or equal to the rim surface. Furthermore, by utilizing the first and second planes of the middle section, the flat, streamlined middle section achieves the effect of minimizing wind resistance.

[0032] The above description is only a preferred embodiment of the present utility model and should not be construed as limiting the technical scope of the present utility model. Therefore, all equivalent modifications made with reference to the present utility model, as well as the methods used, effects achieved, and results of implementation, should still fall within the protection scope of the present utility model and are hereby described together.
