Buffering anti-collision structure of electric vehicle rear axle

Abstract

The invention discloses a buffering anti-collision structure of an electric vehicle rear axle. The buffering anti-collision structure comprises a balancing pole arranged between a rear axle casing and a vehicle frame. The buffering anti-collision structure is characterized in that a lateral collision preventing buffering device is further arranged between the rear axle casing and the vehicle frame. The lateral collision preventing buffering device comprises a lower fixed plate vertically fixed on the rear axle casing and further comprises two buffer springs located on the two sides of the lower fixed plate. The buffer springs are spiral springs, the two ends of the buffer springs respectively act on the lower fixed plate and the vehicle frame, the balancing pole comprises a balancing pole lower section connected to the rear axle casing and a balancing pole upper section connected to the vehicle frame, and a buffering spring is connected between the balancing pole lower section and the balancing pole upper section. The buffering anti-collision structure can relieve automobile lateral impact force, improve automobile safety and further have the advantages of being simple in structure and convenient and quick to install and working stably and reliably.

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
