Abstract
A method for automatic retraction of a pedal of a bicycle. A first electric actuator is provided on a crank, and the pedal is driven to be retracted by the first electric actuator to complete a first retraction, so that long side of the pedal is changed into a front-rear direction from a left-right direction; a second electric actuator mounted on a bicycle frame drives the crank to idle, and the pedal is gradually straightened in the first retraction process to be parallel with the plane of the bicycle frame to complete a second retraction of the pedal. Using this method, the pedal can be conveniently retracted, and the transverse (left-right) occupying space is minimized, thereby facilitating the automatic storage and saving the storage space.
Claims4
A method for automatic retraction of a pedal, comprising a bicycle comprising a bicycle frame, a crank, a central axle, a crankset and the pedal;
- wherein a first electric actuator is provided on a crank, and the pedal is driven by the first electric actuator to retract;
- a second electric actuator is mounted near a central axle of the bicycle frame and drives the central axle to rotate, and then the central axle drives a crankset, the crank and the pedal to rotate around the central axle, so that when the pedal is retracted towards the bicycle frame, a plane of the pedal is gradually straightened to be parallel to a plane of the bicycle frame to complete a complete retraction of the pedal.
