The embodiment of the invention provides a transmission mechanism for linear-to-rotary motion of a pedal device of a rail train, the pedal device and the rail train. The linear-to-rotary motion transmission mechanism comprises a U-shaped mounting part, two rotating shafts and two force arm rod, wherein one end of each force arm rod is fixedly connected with a shaft hole of the corresponding rotating shaft, the rotating shafts are connected between two arms of the U-shaped mounting part, the two rotating shafts are arranged in a spaced mode, and the two force arm rods are kept on the same straight line opposite to each other; the two force arm rods are respectively used for bearing external linear motion; the outer groove bottom of the U-shaped mounting part is used for being fixed to an external device; when the force arm rod bears external linear motion, the U-shaped mounting part drives the external device to rotate. The pedal device comprises the linear-to-rotary motion transmission mechanism. The rail train comprises the pedal device. According to the pedal device, a technical problem that an electric height adjusting mechanism of the pedal device is poor in durability is solved.

    本申请实施例提供了一种用于轨道列车脚踏装置的直线转旋转运动的传动机构,脚踏装置及轨道列车。直线转旋转运动的传动机构包括:包括:U形安装件;两个转动轴和两个力臂杆,力臂杆的一端与转动轴轴孔固定连接,转动轴连接在U形安装件的两个臂之间,且两个转动轴间隔设置,两个力臂杆保持为相背的同一直线;其中,两个力臂杆分别用于承载外部的直线运动;其中,U形安装件的外槽底用于与外部的装置固定;在力臂杆承载外部的直线运动时,使得U形安装件带动外部的装置进行旋转。脚踏装置包括上述直线转旋转运动的传动机构。轨道列车包括上述脚踏装置。本申请实施例解决了脚踏装置的电动高度调整机构的耐用性差的技术问题。
