The invention relates to a getting-on and off pedal device and a vehicle provided with the pedal device. The getting-on and off pedal device comprises a bracket, wherein a rigid pedal is movably assembled on the bracket; a transmission plate is assembled on the bracket along the front-back direction in a guiding manner; the front end of the transmission plate is hinged with the rigid pedal to drive the rigid pedal to extend out of and retract into the bracket; the front end of the bracket is provided with a supporting structure, the height of the supporting structure is less than that of the hinged axis of the transmission plate and the rigid pedal, the supporting structure provides support for the rigid pedal when the transmission plate drives the rigid pedal to stretch out so as to enable the front end of the rigid pedal to descend under the action of gravity, and the supporting structure provides support for the rigid pedal when the transmission plate drives the rigid pedal to retract so as to enable the rigid pedal to overcome the gravity to ascend. The height of the supporting structure is less than the height of the hinged axis of the transmission plate and the rigid pedal, so that the part, which is located between the hinged axis of the transmission plate and the rigid pedal and the supporting structure, of the rigid pedal does not rub the bracket in the process that the rigid pedal stretches out of and retracts into the bracket.
本发明涉及一种上下车踏板装置及安装有该踏板装置的车辆。上下车踏板装置包括支架,支架上活动装配有刚性脚踏板,支架上沿前后方向导向装配有传动板,传动板前端与刚性脚踏板铰接以带动刚性脚踏板伸出和缩回支架,支架前端设有支撑结构,支撑结构的高度低于传动板与刚性脚踏板铰接轴线的高度且支撑结构在传动板带动刚性脚踏板伸出时给刚性脚踏板提供支撑以使刚性脚踏板前端靠重力下降,在传动板带动刚性脚踏板缩回时给刚性脚踏板提供支撑以使刚性脚踏板克服重力上升。支撑结构的高度低于传动板与刚性脚踏板铰接轴线的高度,因此刚性脚踏板在伸出和缩回支架的过程中,处于传动板与刚性脚踏板铰接轴线与支撑结构之间的部分均不会与支架发生摩擦。
