[0013] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0014] Reference Figure 1-4This utility model provides a carbon fiber motorcycle frame, which includes a first beam 1, a second beam 2 fixedly connected to the lower end of the first beam 1, a front stand tube 8 fixedly connected to one end of the first beam 1 and the second beam 2, a side tube 5 fixedly connected to the other end of the first beam 1, and an engine lower support tube 3 fixedly connected to the other end of the second beam 2, forming the main frame of the frame.
[0015] Specifically, a directional rotation shaft 20 is movably connected through the front riser tube 8. A limit ring 15 is fixedly connected to the upper end of the directional rotation shaft 20, and a symmetrical wheel frame 9 is fixedly connected to the lower end of the directional rotation shaft 20 to ensure that the front of the vehicle can turn flexibly and stably.
[0016] Specifically, the side of the first beam 1 is fixedly connected with multiple symmetrical side support rods 14, and the side of the first beam 1 is fixedly connected with multiple symmetrical second reinforcing rods 13. The other end of the second reinforcing rods 13 is fixedly connected to the upper end of the engine lower support tube 3, thereby improving the overall rigidity of the frame.
[0017] Specifically, the other end of the engine lower support tube 3 is fixedly connected to the tail ring beam 4, and the other end of the first beam 1 is fixedly connected to a symmetrical first reinforcing fixing rod 7, with the other end of the first reinforcing fixing rod 7 fixedly connected to one end of the tail ring beam 4.
[0018] Specifically, the other end of the side tube 5 is fixedly connected to the tail support tube 6, which improves the rear layout of the frame.
[0019] Specifically, a symmetrical second shock-absorbing rotating seat 11 is fixedly connected to the tail ring beam 4, and a symmetrical first shock-absorbing rotating seat 10 is fixedly connected to the lower end of the side tube 5, providing a foundation for the subsequent installation of shock-absorbing components.
[0020] Specifically, a first rotating support block 16 is movably connected through the second shock-absorbing rotating seat 11, and a connecting bushing 18 is fixedly connected to the upper end of the first rotating support block 16.

[0021] Specifically, the connecting bushing 18 is movably connected to the connecting rod 19, and the connecting bushing 18 and the connecting rod 19 are movably connected to the shock-absorbing spring 12, thus completing the assembly of the shock-absorbing system.
[0022] Working principle: The frame, consisting of the first beam 1, the second beam 2, the front seat tube 8, the side tubes 5, and the engine lower support tube 3, forms the main framework, bearing the weight of the entire vehicle and its components. The directional rotation shaft 20 inside the front seat tube 8, in conjunction with the limiting ring 15 and the wheel carrier 9, allows for flexible steering of the front end and limits the displacement of the steering shaft, ensuring steering stability. During riding, the side support rod 14, together with the first reinforcing rod 7 and the second reinforcing rod 13, distributes the weight of the engine and other components, as well as the forces generated during riding, to various parts of the frame, enhancing rigidity. The rear ring beam 4 and the rear support tube 6 complete the frame structure, ensuring rear stability. When the vehicle encounters bumps, the first shock-absorbing rotating seat 10 at the lower end of the side tube 5 and the second shock-absorbing rotating seat 11 on the rear ring beam 4, in conjunction with the first rotating support block 16, the second rotating support block 17, the connecting bushing 18, and the connecting rod 19, cause the shock-absorbing spring 12 to compress or extend, absorbing vibrations and reducing the transmission of bumps to the frame and rider, improving riding comfort and handling.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
