AI Technical Summary

Technical Problem

The connection structure of the main beam tube of traditional electric motorcycles is not firmly fixed, which easily leads to increased gaps and connection failures. Furthermore, it is difficult to adapt to the changes in installation position of different models, resulting in poor structural stability and versatility.

Method used

Featuring a threaded sleeve and bidirectional threaded rod design, it achieves a secure connection through bolt fastening and lever structure. Combined with adjustable extension components, it adapts to main beam tubes of different diameters and positions, providing convenient storage and battery protection functions.

Benefits of technology

It improves the stability and reliability of the main beam tube, reduces the risk of component displacement, enhances the adaptability and practicality of the structure, adapts to dynamic compensation after wear, and ensures the sealing and stability of the connection.

Abstract

The utility model relates to the technical field of structural design and reinforcement of electric motorcycle frames, and discloses an electric motorcycle main beam tube reinforcing device which comprises a frame, two connecting rods are fixedly connected to the inner side wall of the frame respectively, and mounting assemblies are arranged on the surfaces of the connecting rods. A threaded sleeve is arranged on the surface of the mounting assembly, an extending assembly is arranged in the threaded sleeve, the mounting assembly comprises an upper clamping plate and a lower clamping plate which are arranged on the surface of the connecting rod, and the threaded sleeve is rotationally connected to one side of the upper clamping plate. According to the reinforcing device for the main beam tube of the electric motorcycle, the mounting assembly and the connecting rod can be firmly fixed through the fastening effect of the bolts, continuous clamping force can be generated through the threaded meshing structure, the loosening tendency can be effectively resisted even if the motorcycle encounters bumping, vibration and other complex working conditions in the running process, the component displacement risk is greatly reduced, and the service life of the motorcycle is prolonged. And the stability and the reliability of the whole structure in long-term use are obviously enhanced.
