The invention belongs to the technical field of truck cab pedals and especially relates to a multifunctional step pedal for a truck. The pedal comprises a main supporting column. A horizontal connecting rod is welded in the middle of the main supporting column; a first pedal is welded above the main supporting column; a second pedal is welded below the main supporting column; a lower surface of the second pedal is connected with a third pedal; movable connecting plates I are hinged to two ends of the upper surface of the third pedal; movable connecting plates II are hinged to two ends of the lower surface of the second pedal; the movable connecting plate I and the movable connecting plate II are connected with each other in a hinged mode; and a rotary spring is arranged at a connecting position, and the movable connecting plate I and the movable connecting plate II are folded under the action of the rotary spring. By pulling the third pedal upwards, defects in the prior art are overcome, a three-layer step pedal is adopted, the third pedal only needs to be located above a tire in a retracting state, stretch out when needing to go up and down and retract in a driving process, peoplecan go up and down conveniently, and a safety risk is reduced.

    本发明属于货车驾驶室踏板技术领域,具体涉一种货车用多功能台阶踏板,包括主支撑柱,主支撑柱中间焊接有水平连接杆,主支撑柱上方焊接有第一踏板,主支撑柱下方焊接有第二踏板,第二踏板下表面连接有第三踏板,第三踏板上表面两端均铰连接有活动连接板一,第二踏板下表面两端位置均铰连接有活动连接板二,活动连接板一和活动连接板二之间通过铰连接的方式相互连接,且连接处设有回旋弹簧,活动连接板一和活动连接板二在回旋弹簧的作用下折叠,将第三踏板向上拉,克服了现有技术的不足,采用三层式台阶踏板,第三踏板只需要在回缩的状态下位于轮胎上方即可,在需要上下的时候伸出,行驶过程中回缩,即方面了人员的上下,又降低了安全风险。
