The invention provides an electric vehicle rear wheel frame structure capable of freely switching between a single wheel and double wheels. The electric vehicle rear wheel frame structure comprises a left supporting arm, a right supporting arm, two rear wheels, a turbine motor and a supporting plate, wherein the upper ends of the left supporting arm and the right supporting arm are movably connected with the supporting plate, and the lower ends of the left supporting arm and the right supporting arm are respectively connected with one rear wheel; the turbine motor is erected between the left supporting arm and the right supporting arm, and the turbine motor is in transmission connection with the left supporting arm and the right supporting arm; guide grooves which are linearly distributed are preset in the lower surface of the supporting plate, a roller is connected to the upper end of the left supporting arm and the upper end of the right supporting arm in a penetrating mode, the roller is pre-embedded in the guide grooves and drives the left supporting arm and the right supporting arm to move in the direction of the guide grooves, and thus the single-wheel and double-wheel free switching is achieved, vertical erecting of the rear wheels can still be achieved in a rear wheel mode, and the use safety of the wheels is ensured.

    本发明提出一种单双轮自由切换的电动车后轮车架结构,包括左支撑臂、右支撑臂、两个后轮、涡轮电机和支撑板;其中,左支撑臂和右支撑臂的上端与支撑板活动连接,左支撑臂和右支撑臂的下端分别连接一个后轮;涡轮电机架设于左支撑臂和有支撑臂之间,并且涡轮电机实现与左支撑臂和右支撑臂的传动连接;支撑板下表面预设有直线排布的导槽,左支撑臂和右支撑臂的上端穿接有一个辊,辊预埋于导槽内,带动左支撑臂和右支撑臂沿导槽方向的移动,以提出一种实现单轮,双轮自由切换,并且在后轮模式下,仍然可以实现后轮竖直的架设,保证轮子的使用安全。
