Electric vehicle safe driving gear engaging mechanism and application thereof

Abstract

The invention relates to the technical field of electric vehicles, and discloses an electric vehicle safe driving gear engaging mechanism and an application thereof. The electric vehicle safe drivinggear engaging mechanism comprises a driving shaft and a shell. A conveying belt is in transmission connection with an outer side of the driving shaft, and a driven shaft is in transmission connectionwith the side, away from the driving shaft, of the conveying belt. According to the electric vehicle safe driving gear engaging mechanism and the application thereof, when a vehicle speed exceeds a safe gear shifting speed, the driving shaft drives the driven shaft to rotate through the conveying belt at the moment, the rotating disc is further driven to rotate, a positive electrode contact can make contact with a first negative electrode contact or a second negative electrode contact under the action of a centrifugal force at the moment, and therefore an effect that an electromagnetic deviceis powered on is achieved. When the vehicle speed exceeds the safe gear shifting speed, the electromagnetic device is electrified, and an electromagnet is attracted to move towards the electromagneticdevice so that a limiting block moves into a groove, the bottom of a gear lever is clamped, and an effect of preventing a driver from changing gears suddenly in a rapid driving process of the vehicleis achieved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a gear-engaging mechanism for safe driving of electric vehicles and its application. Background technique [0002] Electric vehicles refer to vehicles powered by on-board power supplies, driven by motors to drive wheels, and meeting the requirements of road traffic safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic. Electric vehicles are mainly divided into: pure electric vehicles, hybrid vehicles, and fuel cell vehicles. With the needs of environmental protection and the depletion of crude oil resources, electric vehicles have become a national An industry that focuses on supporting development. [0003] At present, electric vehicles only have three gears: forward, reverse and stop, and there is no structural connection between the shifter, brake and accelerator of electric vehicles, so the drive...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a gear-shifting mechanism for safe driving of an electric vehicle and its application, which has the advantage of preventing the driver from suddenly changing gears during the fast driving of the vehicle, and solves the problem of sudden shifting of the fast-moving electric vehicle. This will cause a sharp increase in the reverse direction current of the motor, causing the contacts of the reverse contactor to burn out, which will seriously cause traffic accidents
