Light-weight electric automobile

Abstract

The invention discloses a light-weight electric automobile. The light-weight electric automobile is characterized in that: an automobile body cover member of the electric automobile is made of a high-intensity compound material; an automobile body framework has a high-intensity aluminum alloy space structure; and the automobile body cover member is connected with the automobile body framework through a high-molecule adhesive. The automobile body cover member and the automobile body framework of the whole automobile are made of whole new materials; compared with the weight of a whole steel pure electric automobile in the same type, the weight of the whole automobile having the light-weight design is reduced by 40 to 45 percent, so an aim of light-weight design is fulfilled to the maximum extent, and the investment cost of an automobile body die is low; by adopting an advanced adhering process, the investment cost of welding equipment can be reduced, and the intensity of the whole automobile body can be enhanced. A very good energy-saving effect is achieved, and the continuation running mileage of the whole automobile is increased.

Description

technical field [0001] The invention relates to a lightweight designed pure electric vehicle, in particular to a miniaturized 2-seater and 4-seater passenger electric vehicle. Background technique [0002] At present, the power batteries used in pure electric vehicles are mainly lead-acid, nickel-metal hydride and lithium batteries, and their mass specific capacities are 30-40wh / kg, 45-60wh / kg, 80-110wh / kg, respectively. At present, the mass specific capacity of fossil fuels represented by gasoline and diesel fuel converted by internal combustion engines is about 3000wh / kg, and the mass specific capacity of petrochemical fuels is 30-100 times that of power batteries. Therefore, pure electric vehicles at this stage generally have the defects of large curb weight, short mileage on a single charge, and high power consumption per kilometer, which restricts the popularization and application of electric vehicles. The invention greatly reduces the curb weight through the lightwei...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a lightweight electric vehicle, which mainly uses a new type of high-strength composite material body cover, a high-strength lightweight aluminum alloy skeleton space structure, and a bonding process of high-strength polymer glue. Lightweight design of the whole vehicle, improving the strength and torsional rigidity of the whole vehicle, in order to solve the problem of increased curb weight of pure electric vehicles due to the low mass-to-capacity of the power battery itself, short driving range, and a large proportion of battery cost, etc. problem, realize the energy saving and zero emission of the whole vehicle
