Abstract

The invention provides a light-weight electric vehicle. The technical solution innovatively designs the chassis and suspension structure of the vehicle. The chassis completely covered with disc-shaped metal in the prior art is improved into a cross-beam structure, and the battery box is disassembled at the same time. It is a number of strip-shaped modules, which are used to connect two main beams, so that the battery box is not only used to hold batteries, but also serves as a part of the chassis mechanical structure to carry gravity, thereby reducing the amount of metal used in the vehicle chassis. On this basis, in order to improve the stability of the vehicle, the present invention decomposes the electric motor group into four independent electric motors, and each electric motor forms an independent power module with one wheel, thereby making the weight distribution more uniform; it is better than the electric motor through the connecting rod Hanging under the support frame, the center of gravity is lower, which helps to alleviate the instability caused by the lightweight design of the vehicle. The invention achieves outstanding technical effects through innovative technical improvements, and has good promotion prospects.

Description

technical field [0001] The patent of the present invention relates to the technical field of electric vehicles, in particular to a lightweight electric vehicle. Background technique [0002] An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but the current technology is still immature. Pure electric vehicles, compared with fuel vehicles, the main difference (difference) lies in the four major components, drive motor, speed controller, power battery, and on-board charger. Electric vehicles use fuel cells as the power source. The chemical reaction process of the battery will not produce harmful products, so the pollution of electric vehicles is extremely small. Since the energy conversion efficiency of the battery is 2 to 3 times...
