Problems solved by technology

In order to ensure that the vehicle frame can meet the size and requirements of the vehicle frame design during welding, it is necessary to apply tooling or tires that prevent thermal deformation of metal materials during welding. Designing and manufacturing these tooling or tires will increase the production cost of the metal vehicle frame
Moreover, the metal vehicle frame itself is spliced ​​and welded by thousands of extruded profiles, stamped plates or various mechanically cut parts. Any processing method of these parts requires special processing. Equipment, personnel, molds and molds will increase the cost and time of vehicle skeleton processing
[0005] Furthermore, since the vehicle frame is welded by metal later, the metal material itself has the problem of elastic deformation. Under the influence of long-term force deformation, the vehicle frame will be deformed or even twisted as a whole. When the skeleton is distorted or deformed, both the driving comfort and safety will be greatly reduced
[0006] At the same time, the profile, plate and related parts of the vehicle frame made of metal materials are facing the threat of oxidation and corrosion. In order to deal with the problem of oxidation and corrosion of metal materials, manufacturers need to carry out a series of anti-oxidation treatments on metal materials , this process step will cause serious environmental pollution, if the lack of formal protective measures will seriously damage the health of the operator, and will also increase the cost of the vehicle skeleton
[0007] In addition, due to the technological structure of the metal skeleton and various surface plastic coverings, a more cumbersome assembly process and corresponding labor costs are required during the assembly process
[0008] Finally, the parts and components of the metal vehicle frame are generally produced in different places, and are gathered to the final production place through long-term transportation. The loss caused by the transportation itself and the transportation process will also increase the cost of the entire motor vehicle and cause certain environmental problems. burden

Description

technical field [0001] The present invention relates to the technical field of various power-driven motor vehicles, in particular to the integrated body and frame of motorcycle-type motor vehicles that are driven by electricity or fuel, and aim at carrying and transporting people and things quickly. and its production method. Background technique [0002] In traditional vehicles driven by electricity or fuel, regardless of the power transmission method, the vehicle frame used to carry people, objects and power parts is generally welded with metal materials. Wherein the vehicle frame of automobile or motorcycle needs to use a large amount of metal materials (steel, aluminum, etc.) to be welded. [0003] Since the vehicle frame needs to carry the metal shell, passengers, goods and power parts, it requires very high firmness of the carrying body to ensure the safety of passengers and goods. In this way, the metal-welded vehicle frame needs to use a large number of profiles an...
