Automatic manual accelerator control device and usage method

Abstract

The invention provides a manual and automatic integrated accelerator control device and a use method. The device comprises a vehicle frame, a pedal, an accelerator cable, a connecting rod mechanism, a limiting block, a brake cable, an accelerator executer and a cable blocking plate. One end of the pedal is hinged to the vehicle frame, and the other end of the pedal drives the accelerator cable to move through the connecting rod mechanism. An extension rod of the accelerator executer drives the pedal through the brake cable. The connecting rod mechanism comprises a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, a first connecting rod assembly, a second connecting rod assembly and a reset spring. According to the manual and automatic integrated accelerator control device and the use method, when manual accelerator control is adopted, the connecting rod mechanism is driven to move by stepping the pedal with the foot, and therefore the opening degree of an accelerator is controlled through the accelerator cable; when automatic accelerator control is adopted, the length of the brake cable is changed through the movement of the extension rod of the accelerator executer, the angle of the pedal is continuously changed along with stretching and contacting of the brake cable, and therefore the effect of automatic accelerator control can be the same as that of manual accelerator control. According to the manual and automatic integrated accelerator control device and the use method, an existing mechanism of a tractor can be utilized to the maximum, the device is simple, and control is easy.

Description

technical field [0001] The invention relates to an intelligent agricultural machine, in particular to a manual-automatic integrated throttle control device and a use method thereof. Background technique [0002] With the development of agricultural intelligence, automatic driving has become one of the development trends of agricultural equipment intelligence. Tractor is an important agricultural equipment, in order to realize automatic driving, the accelerator control device must be modified to realize automatic control of tractor running speed. The tractor has a high degree of mechanization, and the throttle control device has a compact structure. If the existing mechanism is completely replaced, the cost and operation difficulty will be greatly increased, and the reliability will be reduced. Therefore, there is a need for a manual and automatic throttle control. On the one hand, it can maximize the use of the existing mechanical structure and retain the manual throttle ...

AI Technical Summary

Problems solved by technology

[0003] A search of existing technologies found that there is still a large gap in the technical field of automatic throttle control for tractors, and most tractors are still at the level of manual throttle control

The automatic throttle control technology applied in industrial vehicles and construction machinery basically replaces the original manual throttle control device with new electromechanical equipment, and does not retain the manual throttle control function.
