Description

Technical Field

[0001] The utility model relates to the technical field of double-beam frame structures for two-wheeled vehicles, in particular to a double-beam frame structure for an electric motorcycle. Background Art

[0002] The frame is a frame-type structure that spans the front and rear axles of the vehicle, commonly known as the beam. It is the base of the vehicle body, just like the human skeleton, supporting and connecting the various assemblies of the vehicle body, so that each assembly maintains a relatively correct installation position and carries various loads inside and outside the vehicle body. Therefore, it must have sufficient strength and rigidity to withstand the load of the vehicle body and the impact from the wheels;

[0003] At present, many two-wheeled vehicle frames use a tubular cradle structure to install batteries. The batteries that need to be installed on the two-wheeled vehicle are installed at the bottom of the cradle frame structure or the bottom of the seat. However, the strength and rigidity of this frame are relatively poor, which affects the stability of the vehicle body. Therefore, we propose a double-beam frame structure for electric motorcycles.
