Collision safety device of electric car

Abstract

The invention relates to a collision safety device of an electric car. The collision safety device comprises an electric power system of the electric car, a collision sensor and an electric driving motor, wherein the electric car electric power system is used for supplying electric power for all mechanical parts in the electric car, the electric power system of the electric car forms a power supply loop which passes through bumper bars, the collision sensor is a device which has excellent electric conducting performance and can immediately generate broken circuit induction when the electric car is collided, the collision sensor is arranged in each bumper bar, and the electric driving motor is connected with and controlled by the electric power system of the electric car. After a car accident happen, when any one of the front bumper bar and the back bumper bar is collided, the collision safety device can ensure that the power supply system of the electric car immediately stops power supply, thereby immediately avoiding secondary or even more damages or dangers caused by mistakenly or deadly stepping on an accelerator and futher protecting the driving safety.

Description

technical field [0001] The invention relates to a safety device for an electric vehicle, in particular to a safety device for collision of an electric vehicle. Background technique [0002] The development history of electric vehicles has a history of more than 90 years from 1920 to the present, and many large international electric vehicle development companies have joined in the development process, so the development of electric vehicles themselves or related technologies is very rapid. [0003] In recent years, environmental changes, greenhouse effect and energy crisis have all formed the development trend of electric vehicles, especially modern people cannot do without cars, and even in European and American countries there are at least one electric vehicles, while driving For human beings, their gender and age are not limited, especially those who are more than 70 years old are driving. Therefore, in terms of safety, it is a part that is attached great importance to by...

AI Technical Summary

Problems solved by technology

[0004] However, at present, there are a considerable number of cases where electric vehicles rush violently after electric vehicle collisions, and even kill quite a few people; In the event of an accident, due to nervousness, fright, or body stiffness when the airbag explodes, the accelerator pedal is accidentally stepped on or dead, resulting in a second or more collisions with the deformed or damaged body of the car that has already been hit , this is very dangerous for the driver or passengers, and it is also one of the safety precautions that the car factory must pay attention to, especially for elderly or female drivers. This is not a violent rush, but a It's the poor design of the car body and the driver's problem
