Description

Technical Field

[0001] This utility model relates to the field of carbon fiber components, and in particular to a carbon fiber component structure with embedded metal components. Background Technology

[0002] Carbon fiber refers to high-strength, high-modulus fibers with a carbon content of over 90%, boasting the highest temperature resistance among all synthetic fibers. It is produced from acrylic and viscose fibers through high-temperature oxidation and carbonization. Carbon fiber is widely used in numerous fields: aerospace, automotive industry, construction engineering, sporting goods, energy electronics, and more. Primarily composed of carbon, carbon fiber possesses properties such as high-temperature resistance, friction resistance, thermal conductivity, and corrosion resistance. It has a fibrous, flexible shape and can be processed into various fabrics. Due to its graphite microcrystalline structure with preferred orientation along the fiber axis, it exhibits very high strength and modulus along the fiber axis. The main application of carbon fiber is as a reinforcing material in composites with resins, metals, ceramics, and carbon, creating advanced composite materials. Carbon fiber reinforced epoxy resin composites have the highest specific strength and specific modulus among existing engineering materials.

[0003] In bicycle manufacturing, bicycle frames are typically made of carbon fiber. Depending on the product's structural assembly requirements, annular bosses are usually incorporated into the carbon fiber components to assist in securing the bearings during assembly, thus improving the stability of the bearing assembly. However, due to limitations in mold design, after the carbon fiber component is formed, the annular boss becomes tightly stuck in the mold, making demolding difficult. This causes inconvenience in production, and direct demolding can easily damage the annular boss, resulting in a high defect rate, high production costs, and generally lower product quality, making it less competitive and unable to meet current demands. Therefore, it is necessary to research a new technical solution to improve upon these problems. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide a carbon fiber part structure with embedded metal parts. This structure effectively solves the problems in the existing technology where, due to limitations in mold design, the bosses of carbon fiber parts with bosses become tightly stuck in the mold after the carbon fiber parts are formed, making it difficult to disassemble the mold, which causes inconvenience to production. Direct demolding can easily damage the bosses, resulting in a high product defect rate, high production costs, and generally poor product quality, making the product less competitive.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A carbon fiber component structure with an embedded metal part includes a body and a metal part. The body is made of carbon fiber, which is characterized by high strength and lightweight, and has good high-temperature resistance, corrosion resistance, and aging resistance. The body has a first extension, one side of which is planar and has a mounting hole with an internal thread. The metal part is embedded in the mounting hole and includes a main body and a second extension extending rearward from the main body. The front side of the main body has an annular boss, and a buffer layer is stacked on the front side of the annular boss to effectively enhance its buffering performance. A wear-resistant layer is stacked on the front side of the buffer layer to effectively enhance the wear resistance of the annular boss. The second extension has an annular structure, and its outer side has an external thread that mates with the internal thread for a threaded connection. The structure is stable, strong, and easy to assemble.

[0007] As a preferred embodiment, the body includes a connecting portion, two first extension portions and two support portions. The two first extension portions are disposed at both ends of the connecting portion and are arranged symmetrically from left to right. The two support portions are disposed at both ends of the connecting portion and are arranged symmetrically from left to right.

[0008] As a preferred embodiment, the two inner sides of the two first extensions are both planar structures, and mounting holes are provided on the two side surfaces. The inner walls of the two mounting holes are provided with internal threads. There are two metal parts, which are arranged opposite each other and are respectively embedded in the corresponding mounting holes. The external threads on the two metal parts are threadedly connected with the internal threads on the corresponding first extensions.

[0009] As a preferred embodiment, the two first extensions and the connecting portion form a U-shaped structure, and the two supporting portions and the connecting portion form a U-shaped structure.

[0010] As a preferred embodiment, the length of the support portion is longer than the length of the first extension portion.

[0011] As a preferred embodiment, the buffer layer is made of rubber, which has high elasticity and good cushioning, shock absorption, wear resistance, weather resistance and chemical corrosion resistance.

[0012] As a preferred embodiment, the wear-resistant layer is an alumina ceramic coating, which has very high hardness and good wear resistance, high temperature resistance, corrosion resistance and insulation properties.

[0013] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

The second extension has an annular structure, and its outer side has an external thread that engages with the internal thread for a threaded connection. In this product structure, due to the first extension of the main body on one side… The surface is planar, so the mold can be easily removed after the main body is formed, which is convenient for operation, facilitates production, greatly reduces product defect rate, and lowers production costs. Furthermore, the metal parts are threadedly connected and embedded in the mounting holes of the main body, which effectively enhances the stability of the connection structure, increases structural strength, and facilitates quick and easy assembly. The annular boss on the metal parts helps to fix the bearing assembly, the buffer layer effectively enhances the buffering performance of the annular boss, improves the flexibility of bearing rotation, and the wear-resistant layer effectively enhances the wear resistance of the annular boss, extending the product's service life, improving product quality, making the product more competitive, and meeting current needs.

The two support portions 13 and the connecting portion 12 form a U-shaped structure. The length of the support portion 13 is longer than the length of the first extension portion 11.

[0031] The metal part 20 is embedded in the mounting hole 102. The metal part 20 includes a main body 21 and a second extension 22 extending rearward from the main body 21. The front side of the main body 21 is provided with an annular boss 211, which is used to assemble with an external bearing. A buffer layer 30 is stacked on the front side of the annular boss 211 to effectively enhance the buffering performance of the annular boss 211.

Then, screw holes are machined on the side of the first extension 11 of the body 10, thereby forming mounting holes 102 and internal threads 103. Finally, the metal part 20 is installed into the mounting hole 102 of the body 10, and the external threads 221 of the metal part 20 are threadedly connected to the internal threads 103 of the body 10.
