The pedal mechanism comprises a pedal component and a driving mechanism which are arranged on a backrest framework, the driving mechanism is connected with the pedal component and drives the pedal component to rotate, open and close, and the pedal mechanism further comprises the crumple protection mechanism connected between the driving mechanism and the pedal component. The crumple protection mechanism absorbs overload pressure transmitted by the pedal component side and provides a buffer stroke for opening and closing of the pedal component, and overload damage of the driving mechanism is avoided. The crumple protection mechanism is additionally arranged between the pedal component and the driving motor, so that the pedal mechanism absorbs energy when reverse input is performed on the driving motor end, and the protection mechanism is used for protecting the motor after the reverse input is released.
本发明公开了具备溃缩保护构件的脚蹬机构,包括设置在靠背骨架上的脚蹬构件及驱动机构,所述驱动机构与所述脚蹬构件相连并驱使脚蹬构件旋转开合,还包括:连接在所述驱动机构与所述脚蹬构件间的溃缩保护机构,所述溃缩保护机构吸收所述脚蹬构件侧传递的过载压力并为脚蹬构件的开合提供缓冲行程,避免驱动机构过载损坏。通过在脚蹬构件和驱动电机之间增设溃缩保护机构,使脚蹬机构在对驱动电机端反向输入时进行吸能,当反向输入释放后保护机构归为保护电机。
