Adjusting support, eight-direction adjusting mechanism and engineering van

Abstract

The invention relates to an adjusting support, an eight-direction adjusting mechanism and an engineering van, and aims at providing the adjusting support simple in structure and applicable, the eight-direction adjusting mechanism and the engineering van. Thus, a driver adjusts the position of an operating platform according to personal details, the control comfort is improved, the production efficiency is improved accordingly, and enterprise benefits are increased. According to the technical scheme, the adjusting support is characterized by being provided with an upper adjusting support and alower adjusting support, and an up-and-down adjusting structure, an upper-and-down adjusting assisting structure and an inclination adjusting structure are arranged between the upper adjusting supportand the lower adjusting support; the up-and-down adjusting structure is provided with a first connecting rod and a second connecting rod, the two ends of the first connecting rod and the two ends ofthe second connecting rod are rotationally connected with the upper adjusting support and the lower adjusting support through pin shafts respectively, and a four-link mechanism is formed by the upperadjusting support, the lower adjusting support, the connecting rod I and the connecting rod II; an up-and-down position locking structure is arranged between the upper adjusting support and the loweradjusting support. The adjusting support and the eight-direction adjusting mechanism are suitable for the technical field of large engineering vans.

Description

technical field [0001] The invention relates to an adjustment bracket, an eight-way adjustment mechanism and an engineering vehicle. It is suitable for the technical field of large-scale engineering vehicles. Background technique [0002] At present, the right side of the cab seat of most engineering vehicles is equipped with an independent control platform, which is generally equipped with operating handles, hand brakes, electrical switches, warning lights and other components. The main function of this control platform is to allow the driver to operate the construction vehicle comfortably, stably and efficiently. [0003] At present, the control platform position adjustment mechanism on the right side of the seat in most engineering vehicle cabs has the following methods: 1. On the right side of the seat, it is fixed on the cab floor and cannot be adjusted; 2. On the right side of the seat, It is fixed on the seat frame and can be adjusted in two directions in the height...

AI Technical Summary

Problems solved by technology

Such position adjustment mainly has the following disadvantages: 1. The angle of the vertical plane cannot be adjusted, that is, the inclination angle of the control platform cannot be adjusted, which does not meet the optimal ergonomics and the driver's operating habits; 2. The angle of the horizontal plane cannot be adjusted, that is, the tilt angle of the control platform The angle with the driver's legs cannot be adjusted, which cannot meet the comfort requirements of drivers with different body shapes and different control habits

Affects the driver's handling comfort, thereby affecting production efficiency
