Uphill reversing-proof device of motor vehicle

Abstract

The invention discloses an uphill reversing-proof device of motor vehicle, which comprises a braking component, a forward and reverse detection switch, a detection gear set, an isosceles triangle support, two unidirectional gears and two locating adsorption blocks, wherein an input end of the detection gear set is driven by a transmission shaft of the motor vehicle; an output end of the detection gear is a forward and reverse detection wheel; the isosceles triangle support comprises a forward waist frame and a reverse waist frame; the top ends of the forward waist frame and the reverse waist frame are fixedly intersected with each other and in fixed rotating joint with the motor vehicle body; the two unidirectional gears are in rotating joint with the bottom ends of the forward waist frame and the reverse waist frame respectively; an end of each unidirectional gear close to the forward and reverse detection wheel turns inwards; the locating adsorption blocks are fixed in the isosceles triangle support in positions close to the forward waist frame and the reverse waist frame respectively; when the reverse unidirectional gear is meshed with the forward and reverse detection wheel, the reverse locating adsorption block adsorbs the reverse waist frame; and the forward and reverse detection switch is closed to start the braking component to brake. The device can detect whether the motor vehicle is reversed under forward gear or neutral gear situation and automatically drive the braking component to brake.

Description

technical field [0001] The invention relates to the electromechanical field of motor vehicles, in particular to an uphill anti-rollback device for motor vehicles. Background technique [0002] With the development of the economy and the improvement of people's living standards, motor vehicles have become a common means of transportation for people's daily life or business activities. The present motor vehicle generally has a parking brake, which is used to prevent the motor vehicle from moving forward and backward when it stops. The stop and advance of the motor vehicle on the uphill section requires the cooperation of the parking brake. For the driver, in the process of frequently stopping and advancing on the uphill section, there will be greater operating intensity, especially for those with insufficient driving experience. The driver is under a lot of driving pressure, and sometimes even improper operation occurs, and the motor vehicle backs up to cause a traffic accide...

Problems solved by technology

The stop and advance of the motor vehicle on the uphill section requires the cooperation of the parking brake. For the driver, in the process of frequent stop and advance on the uphill section, there will be greater operating intensity, especially for those with insufficient driving experience. The driver is under a lot of driving pressure, and sometimes there may even be improper operation, and the motor vehicle reverses backwards, resulting in a traffic accident of tail bumping.
