Monocoque electric vehicle and assembling method thereof

Abstract

The invention provides a load-bearing electric vehicle and an assembly method thereof. The load-bearing electric vehicle includes a frame assembly, a front compartment assembly and a driver's cab assembly; the frame assembly includes a magnesium alloy welded The main body of the frame and the front suspension and rear suspension made of aluminum alloy welding, the front suspension and rear suspension are fixedly connected to the main body of the frame; the front warehouse assembly and cab assembly are mainly made of carbon fiber composite materials have to. By adopting the load-bearing electric vehicle and its assembly method of the present invention, the frame assembly is jointly made of magnesium alloy and aluminum alloy to ensure the strength of the main body of the frame, and effectively absorb the impact of collisions through the collapse of the aluminum alloys of the front suspension and rear suspension. Kinetic energy, reducing occupant injuries, combined with the front cabin assembly and cab assembly made of carbon fiber composite materials, effectively reducing the weight of the vehicle; simplifying the assembly and manufacturing process through modular design, improving efficiency, and also helping to speed up the follow-up of electric vehicles Industrialization development.

Description

technical field [0001] The invention relates to a light-weight, modular load-carrying electric vehicle and an assembly method thereof. Background technique [0002] The current environmental problems in our country are very serious. Smog is raging in every city, and automobile exhaust is one of the main sources of pollution. Under this background, new energy vehicles are increasingly popular due to their advantages in environmental protection, carbon emissions and noise reduction. The attention of the market and the society, such as low-speed electric vehicles have been rapidly developed in Shandong, Hebei and other places and third-tier cities, but the comfort and craftsmanship of this type of electric vehicles are relatively poor, and the market urgently needs to have higher process quality and appearance. And the driving performance of the electric coupe. [0003] On the other hand, with the gradual reduction of oil reserves, electric vehicles, as one of the representati...

Problems solved by technology

However, this electric vehicle focuses on the free assembly and adjustment of the above four modules, and space adjustment is performed by shrinking the longitudinal beams. However, this design will inevitably make it difficult for the electric vehicle to meet the needs of higher speed driving, and it is also difficult to achieve better driving operation. performance
