Electric vehicle stall protection device capable of automatically decelerating

Abstract

The invention relates to the technical field of electric vehicles, and discloses an electric vehicle stall protection device capable of automatically decelerating. The device comprises a rotating shaft, a shell fixedly sleeves the rotating shaft, a connecting pipe is fixedly connected to the interior of the shell, a connecting rod is movably connected to the interior of the connecting pipe, and abalancing weight is fixedly connected to the exterior of the connecting rod. A copper rod is fixedly connected to the interior of the balancing weight, an N pole is fixedly connected to the interior of the shell, an S pole is fixedly connected to the interior of the shell, and a second spring is movably connected to the interior of the shell. When the rotating shaft is in a normal rotating speed state, through the interaction among the rotating shaft, an electric wire, a spring I, a movable block and an electrorheological body, the rotating shaft does not influence the normal use of the electric vehicle when being in a normal rotating speed range, so that the situation that the use of a stall protection device limits the normal use of the electric vehicle is avoided, and the electric vehicle can meet the requirement of daily use.

Description

Technical field[0001]The present invention relates to the field of electric vehicles, in particular, an electric vehicle stall protection device capable of automatically decelerating.Background technique[0002]In recent years, with the continuous improvement of people's living standards, the automobile gradually enters the home of the people, and has become the daily poec tools of most people, but with the increase in the use of automobiles, the environmental pollution is more serious, so the country begins Advocating green and environmentally friendly life, and electric cars should come into such a situation.[0003]Electric cars use the battery to provide power sources for the driving of the car during use, thereby reducing the use of fuels while reducing exhaust emissions, in line with national green environmental life. In the process of using the electric vehicle, the power output is too large due to some external factors or the inside of the electric vehicle, so that the driving s...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an electric vehicle stall protection device capable of automatic deceleration, which has the advantage of being able to slow down the rotation speed of the rotation shaft in time when the rotation speed of the rotation shaft exceeds the normal value, and solves the problem of During the driving process, due to some external factors or internal problems of the electric vehicle, the rotation speed of the power shaft exceeds the normal driving speed range, resulting in the excessive speed of the electric vehicle or the situation that the speed cannot be controlled, which makes the electric vehicle in use. There are safety hazards
