Buffer and anti-collision structure of electric vehicle rear axle

Abstract

The invention discloses a buffer and anti-collision structure for the rear axle of an electric vehicle, which includes a balance bar arranged between the rear axle housing and the vehicle frame, and is characterized in that an anti-collision structure is also arranged between the rear axle housing and the vehicle frame. Side impact buffer device; the anti-side impact buffer device includes a lower fixing plate vertically fixed on the rear axle housing, and also includes two buffer springs located on both sides of the lower fixing plate, the buffer springs are coil springs with two ends Act respectively between the lower fixing plate and the vehicle frame; the balance bar includes a lower section of the balance bar connected to the rear axle housing and an upper section of the balance bar connected to the vehicle frame, and a gap between the lower section of the balance bar and the upper section of the balance bar The connection is provided with a spring for cushioning and shock absorption. The invention can relieve the impact force of the side collision of the automobile, improve the safety of the automobile, and has the advantages of simple structure, convenient and quick installation, stable and reliable operation, and the like.

Description

technical field [0001] The invention relates to a rear-drive electric vehicle, in particular to a buffer and anti-collision structure for the rear axle of the electric vehicle. Background technique [0002] An electric vehicle is a vehicle that uses a battery as an energy source, and converts electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed. The first electric car was produced in 1834 and it was driven by a DC motor. Today, electric vehicles have changed dramatically and come in many varieties. Among them, an electric vehicle (EV) refers to a vehicle powered by an on-board power supply, driven by a motor to drive the wheels, and conforms to 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. [0003] In terms of electric vehicles, the ...

AI Technical Summary

Problems solved by technology

[0005] Existing electric vehicles generally imitate the structure research and development of ordinary cars during research and development, and have the following defects: 1. When the car is hit, it is most likely to cause death due to the side impact of the car, and electric cars are heavier than ordinary cars due to their weight. It is light, so it is more likely to cause the death of the driver if it is subjected to a side impact, and the safety is poor
