Abstract

Disclosed is an urban rail vehicle adjustable driver pedal. The upper portion of a base of the pedal is connected with a four-linkage lifting mechanism. The upper end of the four-linkage lifting mechanism is connected with a rotating mechanism. The rotating mechanism is fixedly connected with a pedal lower cover shell. A pedal upper cover shell is fixedly connected with the upper part of the rotating mechanism. The pedal is connected with a rotating skeleton of the rotating mechanism, and the pedal and the rotating skeleton are lifted synchronously. Tension springs are arranged between the pedal upper cover shell and the rotating mechanism as well as between the base of the pedal and the lifting mechanism correspondingly. A telescopic pneumatic rod is connected with the position between the base of the pedal and a rotating shaft of the rotating mechanism. According to the urban rail vehicle adjustable driver pedal, through the lifting mechanism and the rotating mechanism, the lifting function and the angle adjusting function of the pedal are achieved, requirements of human-machine engineering of all rail vehicle drivers of different heights are met, a more comfortable working environment is provided for the foot part of each rail vehicle driver, and installation and maintenance are convenient.

Description

technical field [0001] The invention belongs to an urban rail transit driver's pedal, and in particular relates to an adjustable driver's pedal for urban rail vehicles that can be used for lifting height and adjusting angle. Background technique [0002] In recent years, with the continuous development and construction of rail transit in major and medium cities, the market demand for various components of rail transit vehicles has become increasingly strong. As an important functional component of urban rail vehicles, adjustable driver pedals provide rail vehicle drivers with foot rest and comfort. corresponding work services. The existing driver's pedals do not have the function of simultaneously raising and lowering the height and adjusting the angle, and cannot meet the ergonomic requirements of all rail vehicle drivers of different heights; they cannot provide a more comfortable working environment for the feet of rail vehicle drivers, which is inconvenient Installation...
