Frame structure of scooter type locomotive

Abstract

The invention relates to a frame structure of a scooter type locomotive, which can be connected with an engine bracket and comprises a first frame, wherein the first frame comprises a head pipe, a left upper pipe, a right upper pipe, a connecting assembly, a left lower pipe and a right lower pipe, wherein the left upper pipe and the right upper pipe are fixedly connected to the head pipe respectively by one ends and respectively extend rearwards and downwards; the connecting assembly, the left upper pipe and the right upper pipe form a triangular structure and are connected to the engine bracket; the left lower pipe and the right lower pipe are positioned under the left upper pipe and the right upper pipe, fixedly connected to the head pipe respectively by one ends and connected to the connecting assembly by the other ends; accordingly, the left upper pipe and the right upper pipe can bear external force or vibration in the length direction to improve the strength of the frame structure of the scooter type locomotive.

Description

technical field [0001] The present invention relates to a scooter frame structure, especially a structure assembled between the head tube and the engine bracket, so as to directly bear external force or vibration in the length direction, and enhance the frame structure The frame structure of the scooter locomotive with high strength. Background technique [0002] Scooter-type locomotives are one of the most common personal vehicles, which have the advantages of small body size, low fuel consumption, and good handling. [0003] Such as Figure 8 Shown is a frame structure 40 of an existing scooter type locomotive, which has a front pipe 41, a main pipe 42, a side pipe 43, a curved section 44 and an engine hanging plate 45, the side pipe The front end of 43 is bent and connected to the main pipe 42, and the rear end extends to the curved section 44, and the engine suspension plate 45 is assembled on the curved section 44 to install the engine and connect the rear wheel of the...

AI Technical Summary

Problems solved by technology

[0004] The side pipe 43 will be subjected to the external force and vibration caused by the front wheel and the rear wheel of the locomotive respectively at the bends near the front end and the rear end, and will be subject to bending moment or shear force, so that the overall vehicle frame structure 40 is susceptible to damage. The action of the force or vibration causes mechanical fatigue or damage at the bend, and the curved and extended frame structure 40 is not only unable to provide good body rigidity, but also has poor handling of the Scooter type locomotive. , and the curved structure will make the assembly of the frame structure 40 more complicated, which is not conducive to the improvement of assembly or production efficiency
