[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] like Figures 1 to 7 As shown, the utility model provides a carbon fiber spoke disk, comprising: a disk body 100 made of carbon fiber material, a mounting hole 110 is opened in the middle of the disk body 100, the periphery of the disk body 100 is composed of a first carbon fiber sheet 140 and a second carbon fiber sheet 150, an installation space for embedding the spoke 200 is formed between the first carbon fiber sheet 140 and the second carbon fiber sheet 150, the installation space comprises a first embedding groove 121 and a second embedding groove 122, the first embedding groove 121 and the second embedding groove 122 are alternately arranged along the circumference of the disk body 100, and the width b of the second embedding groove 122 is greater than the width a of the first embedding groove 121.

[0030] In this embodiment, four first embedding grooves 121 are provided on the circumference of the disc body 100, and four second embedding grooves 122 are provided on the disc body 100. The first embedding grooves 121 and the second embedding grooves 122 are evenly arranged around the disc body 100, so that the spokes 200 can maintain appropriate tension and symmetry after installation to provide good wheel running performance and durability. Lightweight is an important feature of carbon fiber bicycles. The disc body 100 made of carbon fiber weighs only 8 to 10 grams and has high strength, which meets the lightweight requirements of carbon fiber bicycles. In addition, carbon fiber materials have excellent vibration absorption capabilities, which can reduce the vibration and noise generated by the wheel set during driving.

[0031] like Figure 5 As shown, in this embodiment, the first embedding groove 121 is obliquely arranged on the side of the disk body 100. The two ends of the first embedding groove 121 are respectively a first end and a second end, the height of the first end is lower than the second end, the first ends of two adjacent first embedding grooves 121 are lower than the second ends, and the first ends and the second ends of two adjacent first embedding grooves 121 are connected to each other to form a second embedding groove 122.

[0032] The first embedded groove 121 fixes one spoke 200, and the second embedded groove 122 fixes two spokes 200. In this embodiment, the first embedded groove 121 and the second embedded groove 122 can effectively disperse the tension and torsion of the spoke 200, so that it is evenly distributed in the entire spoke system, reducing the risk of local stress concentration, and extending the service life of the wheel set. At the same time, the groove design can make the installation and replacement process of the spoke 200 simpler and faster, reduce the complexity of the operation when maintaining and replacing the spoke 200, and improve the maintenance efficiency.

[0033] In this embodiment, during use, the carbon fiber spokes 200 can be fixed in the first embedding grooves 121, and the spokes 200 in two adjacent first embedding grooves 121 are staggered in the second embedding grooves 122. In the above embodiment, the first end and the second end of the two adjacent first embedding grooves 121 are connected by a transition curved surface, thereby preventing the carbon fiber spokes 200 from being scratched by the transition between the first embedding grooves 121 and the second embedding grooves 122 or preventing the spokes 200 from being bent and deformed.

[0034] The depth of the first embedding groove 121 and the second embedding groove 122 is 5-7 mm. In this embodiment, the depth of the first embedding groove 121 and the second embedding groove 122 should properly accommodate the spoke 200 so that the spoke 200 can be installed firmly and positioned correctly to ensure the structural strength and stability of the wheel set.

[0035] The thickness of the first carbon fiber sheet 140 and the second carbon fiber sheet 150 is 0.4-0.8 mm. In this embodiment, the weight of the plate body 100 is only 8-10 g due to the use of carbon fiber material. The first carbon fiber sheet 140 and the second carbon fiber sheet 150 are thin and have high strength to meet the use requirements.

[0036] The mounting hole 110 is provided with a rotation-stopping surface, and the mounting hole 110 is a regular polygon. In this embodiment, the mounting hole 110 is a regular hexagon, and the corners are provided with rounded corners. The mounting hole 110 is a polygon, which can effectively prevent the disk body 100 from rotating around the rotating axis during the assembly process. At the same time, it simplifies the installation process. In other embodiments, the mounting hole 110 is a square, and the corners are provided with rounded corners.

[0037] The circumferential side of the mounting hole 110 protrudes toward both ends to form mounting portions 130, and the width c between the two ends of the mounting portion 130 is not less than the width b of the second embedding groove 122. In this embodiment, the installation portion 130 can increase the length of the mounting hole 110, increase the contact surface between the mounting hole 110 and the rotating shaft, make the load distribution more reasonable, and improve the structural strength of the disk body 100, and the width between the two ends of the mounting portion 130 is greater than or equal to the second embedding groove 122, which can maintain the distance between the first embedding groove 121 and the second embedding groove 122 and other parts, prevent the first embedding groove 121 and the second embedding groove 122 from being squeezed, and protect the structure of the first embedding groove 121 and the second embedding groove 122.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
