Anti-rolling auxiliary device for electric vehicle driven by push rod motor

Abstract

The invention discloses an anti-rolling auxiliary device for an electric vehicle driven by a push rod motor, which comprises a power supply, a deceleration device, a control mechanism, a driving device and a supporting wheel. When the electric vehicle lightly brakes to decelerate, the driving device can move the supporting wheel down to a position close to the ground, and the supporting wheel is only close to the ground without contact, effectively preventing the wearing of the supporting wheel. When the electric vehicle is completely braked to the bottom, the support wheels are completely on the ground, so that the ground can be supported by the support wheels to prevent sideways during temporary parking, without the need for the user's feet to support the ground. Among them, the driving device uses the push rod motor to cooperate with the swing rod, and the traction line is connected to the middle part of the swing rod. By controlling the push rod motor to push the swing rod, the swing rod is used to pull and swing the bracket to drive the support wheel to move up and down. The swing rod uses Based on the principle of leverage, it effectively reduces the load on the push rod motor and prolongs the service life of the entire driving device.

Description

technical field [0001] The invention belongs to an auxiliary anti-falling device for an electric vehicle driven by a push rod motor. Background technique [0002] With the gradual improvement of people's living standards, pedal electric bicycles (abbreviated electric vehicles) have become the most widely used daily means of transportation for people. Therefore, improving the safety performance of the vehicle and eliminating its potential safety hazards are closely related to millions of households. Before the present invention was made, the existing electric vehicles had the following disadvantages during driving: when temporarily parking, both feet of the driver need to leave the foot-stepping area and stretch out to the ground to support the vehicle. In this state, because the position supported by the feet has exceeded the width of the vehicle, it will cause some inconvenience to the driver: if it is rainy, the shoes and trousers will be wet by the rain and the water flow...

AI Technical Summary

Problems solved by technology

Before the present invention was made, the existing electric vehicles had the following disadvantages during driving: when temporarily parking, both feet of the driver need to leave the foot-stepping area and extend to the ground to support the vehicle

[0005] During the driving process of the electric vehicle, the user will decelerate many times, and the number of riding stops will be less, and the user does not need the support wheel to touch the ground during the deceleration process, only when the user stops, the support wheel needs to be on the ground to prevent the electric vehicle from falling sideways , so the supporting wheels touch the ground every time they decelerate, but the electric vehicle does not completely stop moving forward, so that the supporting wheels wear out rapidly during the deceleration process

[0006] Secondly, stepping on the pedal with a purely mechanical structure causes the support wheel to support the ground, which requires a lot of force. If the user exerts force on one side for a long time, it is easy to make one leg weak and cause discomfort in use.
